Description

River Power Generation System {SYSTEM FOR GENERATING POWER BY RIVER FLOW}

This utility model relates to power generation technology, and more particularly to river water generation system.

Along with the decline of traditional energy such as oil and coal, the state of the world's energy crisis is getting worse. Therefore, the development and use of renewable energy has received special attention. Hydropower is an important component of natural renewable energy and is already one of the main groups of renewable energy generation in the future. The current hydroelectric power generation system has various advantages such as being clean, having a large amount of storage, and being able to obtain and use it indefinitely, and are widely used in regions rich in hydro resources such as rivers and lakes.

The devices commonly used in river power generation in the prior art are turbo-machines, and the main components include vane wheels, power shafts, bearing seats, power output wheels, generators and the like. At the time of work, the rotor wheel is rotated using the water stream, and the electric shaft connected to the rotor wheel turns the generator to convert the kinetic energy of the stream into electrical energy.

However, there is a problem in the river power generation method, because the angle in the water of the medium wing is constantly changed during the movement of the wing wheel, the use of the kinetic energy of the water flow is insufficient, and also the volume of the turbo machine Because of the limitation of size and size, it is difficult to make full use of the river's water flow kinetic energy. In addition, existing river water generators are expensive and difficult to realize because many require dams.

The purpose of this utility model is to provide a kind of river power generation system to increase the utilization rate of the kinetic energy of the water stream to increase the amount of power generation.

In order to realize the above object, the utility model includes a rotary plate fixedly mounted with water flow,

Float floating on the stream,

A blind plate mounted to the floating body,

A flexible chain having one end fixedly connected to the floating body and the other end wound on the rotating plate, and

It includes a generator connected to the rotating shaft of the rotating plate through a transmission,

Inserting the shielding plate in the water flow at the time of power generation, the shielding plate is pushed by the water flow and pulls the floating body to run forward in accordance with the flow of the water stream,

Pull the flexible chain wound when the float moves forward with the flow of water to rotate the rotating plate,

It provides a river power generation system, characterized in that the generator generates power during the rotation of the rotating plate.

As can be seen from the above technical solution, the present practical solution is a technology for generating the horizontal motion of the floating body by the rotation of the rotating plate through the flexible chain by pushing the shielding plate through the water flow to horizontally move the floating body, The angle in the water of the wing wheel of the turbomachine of the technology is constantly changed to overcome the problem that the kinetic energy of the water flow cannot be fully utilized. Although the width of the floating body of this utility model can be made very wide, it is preferable to be close to the area of water flow. This utility model can fully utilize the kinetic energy of water flow, improve the amount of power generation, and can be easily applied to various water bodies.

Hereinafter, the utility model will be described in more detail by combining specific embodiments and drawings.

Example 1 of a river power generation system

BRIEF DESCRIPTION OF THE DRAWINGS It is a figure which shows the structure of Example 1 of the river water power generation system of this utility model. The system can be installed in a body of water having an arbitrary water flow kinetic energy to generate a constant flow of water in the river. The system specifically comprises a rotary plate 3, a float 1, a blind plate 2, a flexible chain 4 and a generator 5. Among them, the rotating plate 3 is fixedly mounted relative to the water flow. For example, it can be anchored to a riverbed or to a dam or riverside. The generator 5 is connected to the rotary shaft of the rotary plate 3 via the transmission 8, and can be generated by rotating the generator 5 when the rotary plate 3 rotates. Preferably, the rotating plate 3 is floated on the steel surface. Specifically, the rotation may be transmitted in the form of a support, a pulley or a gear. The floating body 1 is floating on the water stream. Specifically, the hull used normally can be made into the floating body 1, and such a hull can be called a power generation line. The shield plate 2 is attached to the floating body 1. When power generation, the shielding plate (2) is to be inserted into the water stream, and the direction of the shielding plate and the flow direction of the water stream should have a constant narrow angle. In a comparatively preferred manner, when the direction of the obstruction plate 2 and the flow direction of the current are about 90 degrees, the kinetic energy of the current can be obtained as much as possible. Can be. One end of the flexible chain 4 is connected to the floating body 1, and the other end of the flexible chain 4 is wound on the rotating plate 3. When the floating body 1 runs forward under the propulsion of the water flow, the flexible chain 4 wound up is pulled to rotate the rotating plate 3.

In the power generation process of the river water power generation system of the present embodiment, specifically, the blind plate is first inserted into the water stream, and the blind plate moves the floating body forward under the propulsion of the water stream. The float pulls on the flexible chain and is released from the rotor, which rotates along the direction in which the rotor is released and rotates the generator to generate electricity.

The river power generation system of the present embodiment is generated by rotating the rotor and the generator to the power line running in the forward flow. Since the shielding plate is in current water flow and the angle does not change, the power can be generated by using the kinetic energy of the water flow sufficiently, and the amount of power generated can be significantly increased. Floating bodies are constantly floating in the water stream, which can reduce low drag and are not easily corroded or broken. In addition, the system is simple and easy to construct a large-scale hydroelectric power plant in a large body of water. It is particularly suitable for installation in the Yellow River. Since the ship is not suitable to operate in the Yellow River, it is possible to build a power plant composed of the river power generation system of the present embodiment using a large body of water. Install several sets of rotating plates and power lines in parallel, or install a blanking plate or floating body with a width of water flow, or install the rotating plates and power lines in series so that the operating range of the power lines does not overlap in the direction of the flow of water. Thus, water resources can be utilized to the maximum.

Example 2 of a river power generation system

2 is a view showing the structure of a second embodiment of the river power generation system of the utility model. This embodiment is based on the first embodiment, and further provided with a first power unit 6. The first power unit 6 may be an electric motor or the like, for example. The first power unit 6 may be connected to the rotating plate 3 to drive and rotate the rotating plate 3 when power generation is stopped. The rotation of the rotating plate 3 winds up the flexible chain 4 to draw the floating body back in the direction of the rotating plate 3 so that the flexible chain 4, which is released during power generation, is wound on the rotating plate 3 again.

The technical scheme of the present embodiment can not only generate power while driving in a forward flow, but also can flow back to the starting point by driving the power unit so that the power can be generated again.

It is preferable to reduce the low drag force by removing the shielding plate 2 from the water during the process of the floating body 1 flows back when the power generation stops. Specifically, the portion approaching one end of the obstruction plate 2 is pivotally connected to the floating body 1, and the pivot shaft 7 is horizontally installed so that the third power unit 9 is connected to the pivot shaft 7. Can be connected. When the floating body 1 runs countercurrently and stops power generation, the pivot shaft 7 is rotated by the third power unit 9, and thus, the shielding plate 2 can be rotated until it exits from the water flow. As shown in FIG. 3, the blocking plate 2 is rotated to the surface of the water.

In the above embodiment, the shield plate pivotally connected to the floating body can be easily changed in position. When generating power while driving forward, the screen is inserted into the water, and when the power generation is stopped while driving in reverse flow, the screen is removed from the water to reduce the low effort. Furthermore, when the power is generated according to the flow, it is possible to adjust the magnitude of the propulsion force received by the screen by adjusting the insertion angle of the screen, thereby controlling the running speed of the floating body to adapt to various actual needs.

Embodiment 3 of a river power generation system

4 is a view showing the structure of a third embodiment of the river power generation system of the utility model. This embodiment is similar to the second embodiment. One end of the obstruction plate 2 is pivotally connected to the floating body 1, and the distinction point is that the pivot shaft 7 is vertically mounted so that the floating body 1 flows backward and the power generation shaft is stopped. The third power unit 9 connected to the driving shaft pivots the pivot shaft 7 so that the shield plate 2 coincides with the flow direction of the water flow. That is, as shown in FIG. 4, the shielding plate 2 is rotated to be substantially parallel to the flow direction of the water flow.

The technical solution of the present embodiment can reduce the low force of the floating body in the reverse flow by rotating the screen to reduce the force required to rotate the screen.

Example 4 of a river power generation system

5 is a view showing the structure of a fourth embodiment of the river power generation system of the utility model. This embodiment is based on Example 1. The shielding plate 2 is fixed to the floating body 1, and when the floating body 1 is a hull, the direction of the shielding plate 2 and the direction of a hull become perpendicular | vertical. When the floating body 1 runs in the forward direction, the direction of the obstruction plate 2 and the water flow becomes vertical, so that the maximum flow propulsion force can be obtained. When the power generation of the floating body 1 is stopped and the reverse flow operation is required, the third power unit 9 installed in the floating body 1 can drive the main body of the floating body 1 to the rotation plate 2. It can rotate with the shielding plate 2 until it is substantially parallel with the flow direction of this stream, that is, with the flow direction of the stream.

The technical solution of this embodiment can reach the object of reducing the low effort when the power generation line is returned by rotating the power generation unit body.

Example 5 of a river power generation system

6 is a diagram showing the structure of a fifth embodiment of the river power generation system of the utility model. In the specific application process, the combination of the shielding plate, the floating body, and the rotating plate may be changed in various ways. For example, the number of shielding plates is not limited to one, and several shielding plates can be installed in a floating body. The shielding plate may be installed in parallel or in series depending on the flow direction of the water flow, or may be at an angle, and may be determined according to a specific situation. The combination of the rotating plate and the float can also change.

As shown in FIG. 6 of the present embodiment, the number of the rotating plates 3 may be one, and two flexible chains, that is, the first flexible chain 41 and the second flexible chain 42, are paralleled thereon. I can wind it up. Any one of these flexible chains is wound and the other chain is unrolled. One end of the first flexible chain 41 and the second flexible chain 42 is connected to one float, that is, the first float 11 and the second float 12. For example, when the first flexible chain 41 is in a wound state, the first floating body 11 connected thereto moves forward under the propulsion of water flow, and the wound first flexible chain 41 is released to rotate the rotating plate 3. To generate power by turning the generator (5). The second flexible chain 42 is in the unrolled state, and the second flexible chain 42 is wound around the rotary plate 3 under the propulsion of the rotating rotary plate 3 to pull the second floating body 12 to run backward. The first floating body 11 and the second floating body 12 alternately run along the flow and flow back.

In the course of the work of the river water power generation system of the present embodiment, two floats alternately run along the flow and flow back. As the floating floating body develops, it attracts the other floating body to perform the reverse flow. Referring to the operation of the first floating body as a specific working process as follows.

At the time of power generation, the first floater inserts the shielding plate into the water stream and causes the direction of the shielding plate and the flow direction of the stream to form the first low effort angle. It is preferable that the direction of the shielding plate and the flow direction of the water flow generally make 90 degrees. In this way, the kinetic energy of the water stream can be obtained to the maximum, so that the screen plate can move forward by attracting the first floating body connected to it under the propulsion of the water stream. The first floating body running in the forward direction rotates the rotating plate while pulling the first flexible chain from the rotating plate 3. The rotating rotating plate 3 generates power by turning the generator while pulling the second flexible chain while winding the second flexible chain to the rotating plate to drive the second float connected to the second flexible chain back to the rotating plate. The back floating running second floater removes the shielding plate connected to it from the water stream or rotates it to form a second low effort angle with the direction of the water flow. The second low drag angle should be smaller than the first low drag angle and preferably parallel to the direction of the water flow. In this way, the driving force of the water flow of the first floating body to the obstruction plate is significantly larger than the driving force of the second floating object to the obstruction plate. After the second float returns to the rotating plate, the second float moves forward again and pulls the first floating body to the rotating plate. In this repetitive replacement, the rotating plate rotates in the forward and reverse directions to drive the generator.

In this embodiment, two floats are connected to one rotating plate so that one flows forward while the other flows back, and the two floating bodies are driven to each other, thereby rotating the rotating plate alternately. Specifically, by installing the deflecting device 100 between the generator and the rotating plate, it is possible to drive continuously the generator in the same direction by adjusting the rotation direction of the rotating plate.

The technical solution of the present embodiment can reduce the installation of the power unit, thereby lowering the cost of the installation. Specifically, when building a power plant, several sets of river power generation systems can be installed. For example, several floats can be installed in parallel on the surface of the water and run simultaneously to form a hydropower plant of a certain size.

Example 6 of a river power generation system

7 is a view showing the structure of one embodiment of a specific embodiment 6 of the river water power generation system of the utility model. This embodiment is similar to the solution of Example 5. The number of rotor plates 3 is one, and is connected to the generator 5 via the clutch 10 and the transmission 8. Two flexible chains, that is, the first flexible chain 41 and the second flexible chain 42, can be wound independently through the pulley on the turntable 3. One of the flexible chains is wound and the other flexible chain is unrolled. One float, that is, the first float 11 and the second float 12, is connected to one end of each flexible chain. One of the floats runs forward under the propulsion of the water stream, and is generated by rotating the generator by rotating the rotor as the flexible chain connected to it is released. The other floating body is driven by the rotating rotating plate (3) to run countercurrent. The two floaters alternately run with flow and backflow. The distinction between this embodiment and the fifth embodiment is that the flexible chain of the two floaters is connected to the rotor plate 3 through a pulley, and the running range of the two floaters does not overlap each other in the flow direction of the water stream. As shown in FIG. 7, the first flexible chain 41 of the first floating body 11 is connected to the rotating plate 3 installed on the riverside through the first pulley 101, and the second floating body 12 is connected to the rotating plate 3. The second flexible chain 42 is connected to the rotating plate 3 installed on the riverside via the second pulley 102, the third pulley 103, and the fourth pulley 108. The travel lines of the first floating body 11 and the second floating body 12 do not overlap each other in series.

8 is a view showing the structure of another embodiment of the specific embodiment 6 of the river power generation system of the utility model. Among them, the first float and the second float have a constant distance in the direction of the water flow, and are separated from each other without influence. The first flexible chain and the second flexible chain are connected to the turntable through a properly installed pulley.

The technical solution of the present embodiment can be continuously generated by rotating the alternator alternately with each other, it is possible to avoid tangling or affecting each other between the flexible chain of the float because the operating range does not overlap each other.

Example 7 of a river power generation system

9 is a diagram showing the structure of a seventh embodiment of a river power generation system of the utility model. In this embodiment, there are two rotating plates, namely, the first rotating plate 31 and the second rotating plate 32. On each of them one flexible chain, ie a first flexible chain 41 and a second flexible chain 42, is wound. One of the flexible chains is wound and the other is unrolled. The number of generators 5 is one, and the first transmission device 81 and the second transmission 82 which are respectively connected to the rotational shafts of the first rotating plate 31 and the second rotating plate 32 are respectively the first clutch device 104. And a second clutch device 105 to the generator 5. The first clutch device 104 and the second clutch device 105 may specifically be clutches or ratchet wheels. The other end of the rotating shaft of the first rotating plate 31 is connected to the fourth power unit 106, and the other end of the rotating shaft of the second rotating plate 32 is connected to the fifth power unit 107. One float, that is, the first float and the second float, is connected to one end of each flexible chain, and the flexible chains of the two floats are connected to their turntables through pulleys, respectively. One of the floats is generated by rotating the generator by rotating the rotating plate connected to it while driving forward under the propulsion of the current. The rotating plate connected to the other float rotates under the drive of its power unit and draws the float connected to it to run countercurrent. It is preferable that the running range of the two floats does not overlap each other in the flow direction of the water stream.

Furthermore, in the embodiment, a combination of two alternating rotary plates, a flexible chain, and a floating body is used to generate power by turning one generator into two rotary plates. The clutch controls the joining and blocking of the rotor and generator. Rotating plates, clutch units, generators, and power units can be fixed on the riverside. And pulleys and flexible chains can connect the floats. The two floats alternately flow forward or return back to each other. In addition, the back flow of the floating body can be driven by the power unit. It is desirable that the speed at which the float returns to backflow is faster than the forward running speed of the other floats. This ensures time for the returned floating body to pick up the obstruction plate, thus ensuring the continuous development of the generator.
