Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a medicine room equipped with a disaster prevention device, and more particularly to a medicine room equipped with a disaster prevention device used in a medicine refrigerator or the like.

In warehouses in hospitals and the like where chemicals such as formalin, ether, alcohol, etc. are stored, there is a risk that the chemicals will volatilize toxic gas or catch fire if the containers are damaged. Therefore, in order to minimize damage in such a situation, it is conceivable to divide the storage warehouse into multiple areas and store items in each area. However, if each area is in the form of a completely independent small room, opening and closing the door will be a hassle in warehouses where people frequently come and go, and it will not be possible to respond quickly when changing the layout of the warehouse. It is also unfavorable in terms of cost. Therefore, ideally, during normal times, the warehouse can be used freely without any partition walls, and when a disaster occurs, a partition wall that isolates only the area where the disaster occurred should be lowered from the ceiling. Preferably if you have the facilities. However, such disaster prevention equipment requires the provision of partition walls that can be raised and lowered at all locations within the warehouse, making the structure of the equipment complex and extremely expensive, making the present invention impractical. was created in view of these circumstances, and the purpose is to propose a chemical room equipped with a disaster prevention device that allows easy access to the divided areas of the room and allows for relatively flexible changes to the indoor layout. It is said that

In order to achieve the above object, the present invention provides a shutter device that closes a room partitioned into a plurality of areas by a partition wall, and a built-in shutter disposed on the ceiling of the doorway of each area by hanging the built-in shutter. , an air supply device that supplies air with an air outlet in each area, a fire extinguishing system that has an extinguishing agent outlet in each area, a sensor installed in each area to detect the occurrence of an abnormality, and a sensor that detects the detection signal. It is characterized by comprising a control device that controls the operation of the air supply device, exhaust device, shutter device, and fire extinguishing device in the area where the abnormality occurs when an abnormality occurs.

Preferred embodiments of a chemical room equipped with a disaster prevention device according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a plan view showing a divided structure of a drug warehouse, and FIG. 2 is a system diagram of its disaster prevention device. Warehouse 1 as shown in Figure 1
0 has four storage chambers 14 by two partition walls 12 and 12.
The building is divided into 16 common spaces (corridors, etc.). Each storage chamber 14 and the common space 16 communicate with each other through an open entrance/exit portion 14A, and a shutter device described later is disposed in this entrance/exit portion 14A. Next, the supply and exhaust system for the storage chamber 14 will be explained with reference to FIG. Storage room 14
An air outlet 18 is provided in the ceiling 15 of the building, and from this air outlet 18, a filter 20, a fan 22, and a damper 24 are supplied.
The air taken in is supplied into the room through the route (duct 25). In addition, an air suction port 26 is provided in the ceiling 15,
Indoor air is exhausted from this air blowing port 26 through a path (duct 27) including a damper 28, a fan 30, and an exhaust port 32. Further, a fire extinguishing agent outlet 34 is provided in the ceiling 15, and a halogen gas extinguishing agent is jetted from a gas cylinder 36 from the extinguishing agent outlet 34.

A temperature detection sensor 38 is provided on the ceiling 15, and a detection signal from this sensor 38 is sent to the control device 4o. The control device 40 controls the opening and closing of the extinguishing agent on-off valve 35 , the damper 24 of the air supply duct 25 , and the damper 28 of the exhaust duct 27 . A gas detection sensor 42 is also provided in the storage chamber 14, and a detection signal from this sensor 42 is sent to the control device 40. The control device 4o further drives and controls the air supply fan 22 and the exhaust fan 3o. When the temperature detection sensor 38 detects the occurrence of a fire and when the gas detection sensor 42 detects the occurrence of toxic gas, a signal is sent from the control device 4o to a warning device (not shown), and the warning device emits a warning sound to notify the occurrence of an abnormal situation. etc. will occur. Note that an air conditioner 41 is installed in each storage room 14 to maintain the room at a predetermined temperature and humidity.

Furthermore, a shutter device 48 is provided on the ceiling 15 at the boundary line 14A between the storage room 14 and the shared space 6 (the entrance/exit area). The shape of the shutter device 48 is shown in FIG. 3, and is composed of a winding portion 5o and a flexible shutter 52, and the shutter 52 is made of a noncombustible material such as glass fiber, asbestos fiber, or metal fiber. Ru. The winding shaft 54 of the winding section 50 is operated to wind up and rewind by a motor (not shown), and the shutter 52 is wound up and stored, or unwound and hung down. At the top of the shank device 48, a roller 53 is provided.
．． 53 may be provided so that its installation position can be changed in the left-right direction along the guide rail 55 shown in FIG. The operation of the shank device 48 is controlled by the control device 40.

Further, an air outlet 56 is provided on the ceiling of the common space 16, and air is supplied from the air outlet 56 through a path (duct 57) of a filter 58, a fan 60, and a damper 62. The intake fan 60 and the damper 62 are connected to the control device 40
It is controlled by

The operation of the embodiment according to the present invention constructed as described above is as follows. First, in normal times, the shutter device 4
The shutter 52 of No. 8 is in a rolled up state, so that the user can freely go in and out of the storage room 14 from the common space 16.

Next, when toxic gas is generated due to damage to the container, etc., the gas sensor 42 detects this and sends a detection signal to the control device 40. Based on this signal, the control device 40 operates the shutter device 48 of the storage chamber 14 in the gas generation area,
The shutter 52 is lowered to isolate the area from other areas. At the same time, the control device 40 fully opens the damper 28 and causes the fan 3 to open.
By operating 0, toxic gas is discharged to the outside, and at the same time, the damper 24 is fully opened and the fan 22 is operated to introduce fresh air into the room. This quickly restores the contaminated room to its original state.

Next, when the temperature detection sensor 38 detects the occurrence of a fire, a signal is sent from the control device 40 to the shutter device 48 of the corresponding storage chamber 14, and the shutter 52 is lowered.

In this state, the storage room 14 where the fire occurred is isolated from other storage rooms 14 and the common space 16, and the spread of the fire is prevented. At the same time, the control device 40 sends a stop signal to the fan 22.30 and a close signal to the damper 24.28, thereby stopping the air supply and exhaust system. Next, the extinguishing agent on/off valve 35 is opened in response to a signal from the control device 40, and the extinguishing agent is sprayed from the air outlet 34 to quickly extinguish the fire. High-pressure air is blown from the outlet 56 to create a positive pressure in the common space 16, and it is possible to prevent smoke, toxic gas, etc. from entering the evacuation passage. Such positive pressure control is performed by the control device 4.
This is done by a signal from 0.

As explained above, according to the chemical room equipped with the disaster prevention device according to the present invention, the room is divided into multiple areas by partition walls, and a shutter device is provided at the entrance/exit of each area, so that when an abnormal situation occurs, Since the shutter of the shutter device in the relevant area is hung down to block the damage, it is possible to prevent the damage from spreading to the area. Further, since the shutter device is rolled up during normal times, it is easy to enter and exit each area.
