Detailed Description
For the purpose of making apparent the objects, technical solutions and advantages of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present invention and the descriptions thereof are for illustrating the present invention only and are not to be construed as limiting the present invention.
Examples
As shown in fig. 1, the embodiment is a car as a house energy storage system, which comprises a battery pack 1 and a water pressure structure with a pressure water source, which are all arranged in the car as a house, and also comprises a water pressure conduit and a first three-way valve 4, wherein the water pressure conduit is arranged between the water pressure structure and the battery pack 1 through connection so as to keep water supply communication; the battery pack 1 is internally provided with a fire detection pipe 13, the battery pack 1 is provided with a water inlet and a water outlet which are communicated with the fire detection pipe 13, and the water inlet and the water outlet are respectively connected with an inlet pipe 11 and an outlet pipe 12; the hydraulic line is kept connected to the inlet pipe 11 and the outlet pipe 12 by means of the first three-way valve 4.
The fire detection tube 13 technology originated in the 20 th century as part of an automatic fire extinguishing system intended to respond and control fires promptly. With the continued development of technology, these systems have become more efficient and reliable, becoming an important component of modern automatic fire suppression systems. The fire detection tube 13 is widely used in commercial buildings, industrial facilities, warehouses, vehicles, and home environments. They are particularly suitable for areas where conventional smoke detectors cannot be or are inconvenient to install, providing a reliable means of fire control for a variety of applications. The fire detection tube 13 is typically made of polyvinyl chloride (PVC), polyethylene (PE) or other similar heat sensitive plastic. These materials are capable of rapidly softening and melting at high temperatures. The melting temperature of the different materials is between 57 ℃ and 260 ℃, and the materials with different melting temperatures can be selected according to the specific application requirements. The diameter, length and thickness of the fire detection tube 13 can be customized as desired, and is designed to be lightweight and easy to install. When the preset trigger temperature is reached, the fire tube 13 melts, causing the internal extinguishing agent (e.g., water, foam or dry powder) to be released and sprayed directly onto the fire source. This quick response mechanism allows the fire tube 13 to effectively control the fire during the early stages of the fire. When the car as a house energy storage system works, the fire detecting tube 13 is used for directly sensing the heating condition inside the battery in the battery pack 1. The battery pack 1 is an energy storage unit of the system, and the hydraulic structure is connected with the battery pack 1 through a hydraulic conduit so as to ensure water supply connectivity. The hydraulic structure is communicated with the hydraulic guide pipe, the hydraulic guide pipe is used for maintaining the battery pack to apply hydraulic pressure, when the battery pack 1 is abnormally high in temperature and reaches the trigger temperature, the fire detection pipe 13 is melted at high temperature to cause damage, a water source in the hydraulic structure is conveyed into the battery pack 1 along the first three-way valve 4 through hydraulic pressure, and the fire detection pipe 13 is filled with the water source to rapidly cool and extinguish fire.
Further, in order to enable the pressurized water source to be flushed into the battery pack 1 more quickly, the device further comprises a buffer device which is communicated with the water pressure conduit; the inside of the fire detection tube 13 is provided with air pressure, and the fire detection tube 13 is used for keeping the pressure load of the air pressure in the tube through the air tightness of the buffer device. The system is set to be in a pressure balance state of air pressure and water pressure, and a certain amount of water pressure and air pressure load are maintained in the system. The control of the air pressure in the fire detecting tube 13 is realized through air sealing, and the balance of the water pressure and the air pressure is adjusted by the buffer device. The fire detection tube 13 is positioned in the battery pack 1 and is provided with air pressure in the tube, the air pressure is communicated with the water inlet and the water outlet, the air is sealed through the buffer device, and the air pressure in the fire detection tube 13 is maintained. The water inlet and the water outlet are connected to the battery pack 1, respectively, so that water can enter and exit the battery pack 1. When the hydraulic buffer device works, the water delivery pressure of the hydraulic structure is started, so that the hydraulic pressure structure keeps delivering hydraulic pressure load to the buffer device, and the buffer device is in a state of keeping the balance of air pressure and water pressure. When the battery pack 1 is abnormally high in temperature or rapidly fires, the fire detection pipe 13 is melted at high temperature, and the pipe body of the fire detection pipe 13 is melted and broken, so that gas in the fire detection pipe 13 flows out rapidly, the initially set gas pressure value is reduced rapidly, the buffer device is changed into a pressure imbalance state, the gas pressure value is far lower than the water pressure value, the pressure load in the device is inclined towards the battery pack 1, a water source in the water pressure structure is conveyed into the battery pack 1 along the first three-way valve 4 through water pressure, and the fire detection pipe 13 is filled with the water source for rapid cooling and fire extinguishing. In a specific implementation, in order to increase the cooling efficiency and speed up the fire extinguishing, the first three-way valve 4 may be a mixed three-way water valve, which allows the fluid to flow out from one of the outlets, while the other outlet is kept open, so that the pressurized water source can reach the inside of the battery pack 1 through the fire detection tube 13 more quickly.
As a specific embodiment, in a specific implementation, it is preferable that the battery pack 1 is provided with an abnormal current detection device and a circuit breaker in signal connection. When a fire breaks out inside a lithium iron phosphate battery, some complex electrochemical reactions are usually accompanied. These reactions can lead to the generation of electrical currents, the fire conditions of which mainly include short-circuit faults and battery chemical reaction faults. A path is formed between the positive electrode and the negative electrode of the battery when a short circuit fault occurs, so that the current in the battery may be increased; the fire may cause thermal decomposition or oxidation-reduction reactions of the internal materials of the battery, which may generate electrons and ions. These electron and ion flows may also constitute an electrical current. Therefore, the abnormal current detection device can monitor whether the abnormal current exists in the battery pack in real time, can sense the change of the current, and triggers corresponding reaction when the abnormal current level exceeds a set threshold value. Once an abnormal current is detected, the system triggers the action of the circuit breaker, which will cut off the connection of the battery pack to other circuits. A circuit breaker is an electrical protection device commonly used to interrupt an electrical circuit to prevent the risk of overcurrent. When abnormal fire of the lithium battery is detected, the rapid isolation of the battery pack and the circuit protection of the system are realized through the rapid action of the circuit breaker, so that the risk of fire spread can be rapidly reduced, and the coping capacity of the system to emergency is improved.
Further, as a possible embodiment, the hydraulic pressure conduit includes a first conduit 2 and a second conduit 21, and the battery pack 1, the first conduit 2, the buffer device, the second conduit 21, and the hydraulic structure are sequentially in communication; the buffer device comprises a buffer bottle 6 and a bottleneck valve 5, the pipe body ends of the first guide pipe 2 and the second guide pipe 21 respectively extend to the lower part and the upper part of the inside of the buffer bottle 6, and the bottleneck valve 5 is arranged at the bottleneck of the buffer bottle 6 and used for keeping the buffer bottle 6 open and closed. The division of the hydraulic pressure conduit into the first conduit 2 and the second conduit 21 serves to promote flexibility in pressure load regulation so that the transfer of hydraulic pressure can be controlled more accurately when dealing with fire. The introduction of the buffer device improves the control of the system on the gas pressure in the battery pack 1, and the gas sealing in the buffer bottle 6 is realized through the opening and sealing of the bottle mouth valve 5, so that the gas pressure can be orderly regulated and controlled. The bottleneck valve 5 is designed for controlling the state of the buffer bottle 6, and can be opened for air pressure regulation and control and closed for preventing air leakage. This design helps to respond quickly when needed and ensures an effective containment of the gas. The pipe ends of the first pipe 2 and the second pipe 21 extend to the lower part and the upper part of the inside of the buffer bottle 6, respectively, because water is accumulated in the lower part of the inside of the buffer bottle 6 and gas is accumulated in the upper part of the inside of the buffer bottle 6. The bottleneck valve 5 is used for sealing the buffer bottle 6 to keep the pressure load state. After the abnormally high temperature battery pack 1 and the fire detection tube 13 are repaired, the bottle opening valve 5 is opened to perform air injection on the fire detection tube 13 so as to maintain the air pressure load again.
More, as a specific application, the upper side wall of the inside of the buffer bottle 6 is further provided with a pressure sensor 61 with a pressure gauge for respectively monitoring the variation of the air pressure and the water pressure in the buffer bottle 6. When the battery pack 1 is in the monitoring air pressure state, whether the potential high-temperature damage condition of the fire detection tube 13 is about to exist or not can be estimated by observing whether the air pressure value has abnormal fluctuation or not, so that the possible abnormal high temperature of the battery pack 1 can be judged in advance. When the fire detection tube 13 is damaged due to abnormal high temperature, and the air pressure value suddenly drops, the water source in the buffer bottle 6 is immediately conveyed into the battery pack 1 by the water pressure at the moment, if the total water source in the water pressure structure is continuously supplied with water in the process of monitoring the water pressure by the pressure sensor 61, if the water pressure value is kept at a stable value in a plurality of seconds, the abnormal high temperature of the current battery pack 1 is automatically judged to be still continuous, and the battery pack 1 of the current motor home can be judged to need better fire-fighting facilities in advance.
Further, as a possible embodiment, the battery pack 1 includes a battery connector 14 and a plurality of individual batteries connected in sequence, each of the individual batteries being connected by the battery connector 14; each independent battery is internally provided with a U-shaped fire detection tube 13, and each independent battery is provided with two sub-ports which are respectively connected with two ends of the internal fire detection tube 13; the inlet pipe 11 and the outlet pipe 12 are connected to sub-ports of the individual cells at the head end and the tail end, respectively. Through the battery connector 14, the individual batteries can be assembled into the battery pack 1 in a sequential connection manner, and the connection manner makes the system easier to maintain and expand, and simultaneously, can effectively manage a plurality of battery units, and simultaneously, obviously promotes the detection range and the detection probability of abnormal high temperature in the battery pack 1. The fire detection tube 13 is arranged in each independent battery in a U-shaped tube mode, and the tube body of the fire detection tube 13 can be divided into each independent battery to a larger extent on the premise of not increasing the complexity of the tube body, so that the probability of detecting abnormal high temperature points in each independent battery is obviously improved. Preferably, in a specific application, as shown in fig. 4, a battery interlayer 15 is further provided in this embodiment, and a gap capable of placing the battery interlayer 15 and allowing a fire extinguishing water source to pass through is left between different independent batteries, and surrounding states are completed below and around each independent battery through the battery interlayer 15. After the water source gushes into the battery pack 1, because the fire detection pipe 13 is damaged, the fire extinguishing water source can gush out from the damaged independent battery, and the damaged independent battery can be soaked under the surrounding of the battery interlayer 15, so that each face of the independent battery can keep contact with the fire extinguishing water source, the effect of cooling and fire extinguishing can be optimal, and meanwhile, the accuracy of selecting cooling and fire extinguishing for the damaged independent battery can be improved, so that the water source can be concentrated in the damaged independent battery at the first time.
Further, in the above embodiment, the outlet pipe 12 is withdrawn from the first three-way valve 4, the tail of the first pipe 2 is used as the inlet pipe 11, the sub-port at the end of the battery pack 1 is connected with an outlet pipe 17, and the end pipe body of the outlet pipe 17 is provided with a valve 16. In operation, the diaphragm water pump 3 is pressurized by hydraulic pressure by activating a pressure switch provided in the diaphragm water pump, and the fire detection pipe 13 in the battery pack 1 is kept under an air pressure load. When the battery pack 1 is abnormally high in temperature, the fire detection pipe 13 is damaged, the air pressure load suddenly drops instantly, and the pressure water source is quickly charged into the battery pack under the action of the water pressure load. After the water source has been flushed to the outlet conduit 17 of the terminal end port of the battery 1, the water flow is led away with the valve 16 kept open.
Further, as one possible embodiment of the hydraulic structure, the hydraulic structure comprises a water supply tank and a diaphragm pump 3 with a pressure switch, the second conduit 21 is connected to the water outlet of the water supply tank toward one end of the hydraulic structure, and the diaphragm pump 3 is provided on the second conduit 21. The water supply tank adopts a mutually communicated upper and lower layered structure, the upper layer is a first tank body 31 communicated with an external water source, and the lower layer is a second tank body 32 communicated with the second guide pipe 21. The design improves the utilization rate of the system to the water source and ensures that enough water resources are supplied in the fire extinguishing process. The second conduit 21 ensures communication between the water pressure structure and the water source by being connected to the water outlet of the water supply tank, while facilitating the operation of the diaphragm water pump 3. The diaphragm pump 3 is a pump that pushes liquid through movement of a diaphragm, and is generally capable of providing a relatively uniform flow rate, and is capable of better preventing cross-contamination of the liquid in the pump with outside air or other substances due to isolation of the diaphragm. The diaphragm pump 3 is designed with a pressure switch so that the pump can provide a hydraulic load to the system by opening the pressure switch when the system is required for preliminary work so that the buffer bottle 6 maintains pressure balance by the water pressure and the air pressure. By introducing the water supply tank and the diaphragm water pump 3, the system increases the management and regulation capability of the water source, and ensures that the system can timely and effectively provide enough water flow for fire extinguishment when a fire occurs. These design elements help to improve the fire extinguishing efficiency of the system and the utilization rate of water resources, and increase the reliability of the system. The working process of the pressure switch is as follows: when the fire detecting pipe 13 is not damaged, a certain air pressure exists in the system, the pressure switch can automatically supply water to apply pressure, the pressure load is preset to the maximum value, and when the applied pressure reaches the maximum value, the pressure switch can be automatically disconnected, so that the system is kept in a standby state, and the condition of overvoltage of the system can be avoided while the pressure load of the system is kept. When the fire detecting tube 13 is broken, the pressure load of the first conduit 2 is reduced, and the water pressure load of the second conduit 21 is also reduced, so that the pressure switch can be restored to the closed state. In a specific use, the diaphragm pump 3 has a certain adsorption force to the water source in the hydraulic structure, so that the water source can enter the second conduit 21 more effectively.
Further, as a possible embodiment, the water supply tank is configured as an upper and lower layered structure, the upper layer is a first tank 31 communicating with an external water source, and the lower layer is a second tank 32 communicating with the second conduit 21. The first tank 31 on the upper layer is communicated with an external water source, and the system can acquire a fresh water source in time by being connected with the external water source. The lower second tank 32 communicates with the second conduit 21 so that water flow can enter the hydraulic structure in order to supply water to the system in the event of a fire. The upper box body and the lower box body are communicated with each other, so that the system is allowed to more flexibly regulate and control water flow distribution, and the stability of the system is improved. Even when the water source is in supply, the stored water source in the second tank 32 may still provide the system with a certain amount of cooling and fire extinguishing capability, and this redundancy helps to reduce the single point failure risk of the system. Meanwhile, the first box body 31 is communicated with an external water source, so that the maintenance and the management of the water supply tank are facilitated, and the system can be periodically checked and maintained through the external water source, so that the system can be in a good working state at any time.
In the specific implementation process, as the fire-extinguishing water source is directly connected into the water storage tank of the motor home, the second guide pipe 21 is connected to the bottom of the second box 32, and meanwhile, as part of water source at the bottom is below the interface, part of water remains in the second box 32 at the lower layer in the process of extracting the fire-extinguishing water source by the diaphragm water pump 3, and therefore, the connection port of the second guide pipe 21 and the second box 32 can be provided with a certain height on the second box 32. When the fire-extinguishing water source of the first tank 31 is used up, a part of the water source still remains at the bottom of the second tank 32, so as to perform emergency cooling fire-extinguishing work when the water source is nearly used up. In the specific setting process of the system, a sudden stop switch can be arranged on the diaphragm water pump 3, when the fire or abnormal high temperature phenomenon of the battery pack is controlled or extinguished, a user can stop the diaphragm water pump 3 by manually closing the sudden stop switch, and the diaphragm water pump can be arranged at corners or other hidden places of the system in the installation process, so that the occupied space of the system is saved.
As a specific application, the external water source communicated with the first box 31 is a caravan water storage tank arranged in the caravan. The commonly used water storage tank of the caravan can be loaded with tens to hundreds of liters of water, and the water storage tank of the caravan is communicated with the system, so that the system can conveniently acquire a water source from the water storage tank of the caravan, the water source carried by the caravan can be conveniently utilized when the caravan runs or stops, dependence on external water sources is reduced, and the system can still use the water source carried by the caravan to carry out emergency fire extinguishing under the condition that the water source is not easily available in some remote areas. Meanwhile, the water storage tank of the caravan can provide larger water capacity for the system, so that the available water source is increased during fire extinguishment, and the fire extinguishment efficiency is improved, especially in the fire extinguishment process requiring a longer time. Because the limo water storage tank is a part of the limo, the system has certain mobility, so that the system can be moved to different positions more easily when needed, and emergency situations in different scenes can be well adapted. Further, in the embodiment, on one hand, the battery pack 1 is located in a sealed metal box in a motor home, the fire detection tube 13 is located in the upper half part of the battery pack 1, after the fire detection tube 13 is broken, the fire extinguishing water source can submerge the whole battery pack, and the fire extinguishing water source can be ensured to cover the whole area of the battery pack, so that full coverage is realized in the fire extinguishing process. On the other hand, in the course of cooling and extinguishing the fire by the fire extinguishing water source, the fire extinguishing water source consumes the abnormally high temperature or the heat of ignition generated by the battery pack 1 by evaporation. In a reference background of about 25 degrees at normal temperature and 1 atmosphere at normal pressure, the heat of vaporization per kilogram of water is about 2200-2300 kilojoules, i.e., 1 kilogram of water is completely vaporized and can consume about 627 watts of heat energy. While battery 1 uses lithium iron phosphate cells with an energy density of up to about 180 watt-hours per kilogram of cell. Therefore, in practical application, at least about 3.4 kg of total heat of the lithium iron phosphate battery can be consumed per kg of water under the condition that additional water is not taken into account. And in the actual process, the specific heat consumption heat of water is also involved, so that the heat consumed by each kilogram of water can be more. The hundreds of liters of water that can be stored on a caravan is sufficient to prevent the abnormal high temperature conditions of the battery multiple times, thus enhancing the system's ability to handle multiple potential fire events over a longer period of use. The present embodiment generally consumes heat released at abnormally high temperatures or fires generated by the battery pack 1 by means of evaporation. The evaporation heat of the water causes the water to change from a liquid state to a gaseous state, absorbing heat, thereby reducing the temperature of the surrounding environment, preventing the spread of fire, and rapidly reducing the temperature of the battery pack.
Further, as a supplementary embodiment, the device further comprises a pressure measuring conduit 22 and a second three-way valve 41, wherein the side wall of the first box 31 is sequentially communicated with the side walls of the pressure measuring conduit 22 and the second conduit 21, and the side walls of the pressure measuring conduit 22 and the second conduit 21 are communicated through the second three-way valve 41; the diaphragm water pump 3 is arranged on the second conduit 21 between the second box 32 and the second three-way valve 41; the pressure measuring conduit 22 is provided with a pressure measuring valve 51 for detecting water pressure and opening and closing the passage of the pressure measuring conduit 22. The pressure measuring conduit 22 is used for periodically detecting the water pressure load capacity of the diaphragm water pump 3 under the cooperation of the second three-way valve 41. In particular applications, the second three-way valve 41 may alternatively be a switching three-way valve, in which case the valve element or disc may be rotated or moved to cause fluid to flow from one outlet to the other; when the valve spool or disc is in a particular position, it directs fluid to one outlet port and the other outlet port is closed. When the valve spool or disc rotates or moves, it will switch the outlet and change the direction of fluid flow. In operation, when the diaphragm pump 3 on the second conduit 21 is pressure-loaded, the second three-way valve 41 is switched so that water flows not to the buffer bottle 6 but to the pressure measuring conduit 22. Since the pressure measuring conduit 22 is flowing to the first tank 31, the detection of the water pressure intensity can be maintained in a circulating manner. When the pressure measuring valve 51 is used for measuring that the water pressure normally needs to restore the pressure load maintenance of the system, the second three-way valve 41 is adjusted to adjust the passage from the pressure measuring conduit 22 to the buffer bottle 6, and then the branch of the pressure measuring conduit 22 is closed, so that the diaphragm water pump 3 can be normally started. The pressure measuring valve 51 typically has a built-in pressure measuring device that can directly measure the pressure of the fluid as it passes through. They are typically used to monitor the pressure in the system and communicate this information to a monitoring system or meter via an internal sensor.
