Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a combined energy dissipation and power generation device installed on the surface of an overflow dam. Background Technology

[0002] In water conservancy and hydropower projects, overflow dams are a common type of water conservancy structure, serving as both water-retaining and water-releasing structures. When the water level exceeds the safe level, water flows out from the overflow dam, which is commonly referred to as water discharge. When water discharge begins, different water levels and flow velocities all have a certain scouring effect on the overflow surface and its sides. When the water level is high and the flow velocity is too great, the scouring of the overflow dam to a certain extent will cause some damage to the overflow dam surface. The overflow surface is not easy to repair, so it is necessary to consider solving the energy dissipation problem of traditional overflow surfaces. In addition, considering that the water flow on the overflow surface has a certain kinetic energy, direct energy dissipation would result in energy waste. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a combined energy dissipation and power generation device installed on the spillway surface to solve the aforementioned technical problems.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0005] A combined energy dissipation and power generation device installed on the surface of an overflow dam includes a dual-purpose rotational and translational energy dissipation and power generation device. The dual-purpose rotational and translational energy dissipation and power generation device includes an energy dissipation and power generation plate and a rotational and translational combined system. The energy dissipation and power generation plate includes a wall with multiple water passage holes. Each water passage hole contains a door and a hydroelectric power generation device, with the hydroelectric power generation device located inside the door. The rotational and translational combined system enables the energy dissipation and power generation plate to rotate and move back and forth relative to the overflow dam body.

[0006] Preferably, the rotation and translation system includes a first translation push-pull system and a telescopic rotation system. The first translation push-pull system includes a first push-pull support, a first translation push-pull telescopic rod, and a first shaft disposed at the power output end of the first translation push-pull telescopic rod. A first rotational power device capable of driving the first translation push-pull telescopic rod to rotate is disposed within the first push-pull support, and a groove cooperating with the first shaft is disposed on the back of the wall. The telescopic rotation system includes a rotation support, a rigid telescopic rod, and a second shaft. A second rotational power device capable of driving the rigid telescopic rod to rotate is disposed within the rotation support, and a groove cooperating with the second shaft is disposed on the back of the wall.

[0007] Preferably, the rotation and translation system further includes a second translation push-pull system. The telescopic rotation system is located between the first translation push-pull system and the second translation push-pull system. The second translation push-pull system includes a second push-pull support, a second translation push-pull telescopic rod, and a third shaft disposed at the power output end of the second translation push-pull telescopic rod. The second push-pull support is provided with a third rotational power device capable of driving the second translation push-pull telescopic rod to rotate. The back of the wall is provided with a channel that cooperates with the third shaft.

[0008] Preferably, the power output end of the second rotary power device is equipped with a rotating shaft, and the rigid telescopic rod is connected to the rotating shaft.

[0009] Preferably, it also includes a left energy dissipation plate and a right energy dissipation plate, which are disposed on both sides of the energy dissipation and power generation device 1. A water inlet is formed between the left and right energy dissipation plates. When the energy dissipation and power generation plate moves forward to its limit position, the wall can block the water inlet. When the energy dissipation and power generation plate moves backward to its limit position, there is a distance between the wall and the water inlet, allowing the water inlet to be open.

[0010] Preferably, the left and right energy dissipation plates are symmetrically arranged relative to the wall; a left rotation power device is provided on the side of the left energy dissipation plate away from the wall, the left rotation power device is located on the overflow dam body, and the power output end of the left rotation power device is connected to the left energy dissipation plate; a right rotation power device is provided on the side of the right energy dissipation plate away from the wall, the right rotation power device is located on the overflow dam body, and the power output end of the right rotation power device is connected to the right energy dissipation plate.

[0011] Preferably, the first rotary power device, the second rotary power device, the third rotary power device, the left rotary power device, and the right rotary power device are all electric motors.

[0012] Preferably, the water passage is a gradient hole, wherein the area of ​​the end of the gradient hole near the inner side of the wall is smaller than the area of ​​the other end.

[0013] Preferably, the door is connected to the wall via an elastic pivot. In its original state, the door is perpendicular to the water passage and blocks the water passage. When water flows through the water passage and impacts the door, the elastic pivot is squeezed by the water pressure, causing the door to rotate and opening the water passage.

[0014] Preferably, the door is a double door.

[0015] The combined energy dissipation and power generation device installed on the spillway dam surface provided by this invention has at least the following functions when in use.

[0016] 1. Power Generation Function of the Device: The power generation function of this invention is mainly realized by a hydroelectric power generation device located on the rotary-translational dual-purpose energy dissipation power generation device. Multiple small hydroelectric power generation devices can be used in this application to achieve the power generation function. The hydroelectric power generation device is located at the bottom of the water passage hole and operates in conjunction with a door installed inside the water passage hole to achieve the corresponding power generation function. When water flows through the rotary-translational dual-purpose energy dissipation power generation device, it impacts the hydroelectric power generation device, converting the kinetic potential energy of the water flow into electrical energy to generate electricity. The generated electricity can be used for the real-time operation of the device or stored in a storage tank for later use. When there is no water flow, the door is closed, providing a certain degree of protection for the power generation device and improving the durability of the device.

[0017] 2. Energy dissipation function of the device: The energy dissipation principle of the present invention is to reduce the flow velocity of the upstream flow of the overflow dam by using an energy dissipation plate. In the initial state, the energy dissipation plate is perpendicular to the water flow direction. When the water flows through the energy dissipation plate, it consumes part of the kinetic energy of the water flow, thereby achieving energy dissipation.

[0018] As the water flow velocity increases, the operating state of the device can be adjusted, moving the energy dissipation and power generation plate backward. The main process involves the first translational push-pull system retracting its first telescopic rod, causing the energy dissipation and power generation plate to move backward. The second translational push-pull system operates synchronously with the first system, arranged symmetrically to prevent the energy dissipation and power generation plate from shifting during the translation process. At this time, the rigid telescopic rod on the telescopic rotation system retracts, controlling the rotating shaft 1-2bb to rotate clockwise, ultimately causing the device to move backward.

[0019] When the water flow velocity decreases, the energy dissipation and power generation plate moves forward. The main process is that the first translational push-pull telescopic rod of the first translational push-pull system extends forward, and the energy dissipation and power generation plate moves forward. The second translational push-pull system operates synchronously with the first translational push-pull system. At this time, the rigid telescopic rod on the telescopic rotation system extends, controlling the rotating shaft to rotate counterclockwise, ultimately causing the device to move forward.

[0020] 3. Flood discharge function of the device

[0021] The flood discharge function of this invention is mainly realized when the upstream water level of the overflow dam is very high, and the inflow water level and flow velocity on the overflow surface are also very high. At this time, the water flow has a great impact on the overall device. In order to ensure that the overall device does not affect the flood discharge of the upstream flow, the device needs to be operated from the initial state to the flood discharge state.

[0022] The process from the initial state to the flood control state: The first and second side sliding push-pull systems are not operational. The rigid telescopic rods on the telescopic rotation system retract, and the rotating shaft rotates counterclockwise. At this time, the wall rotates around the second and first axes, thus coordinating with the overall rotation, thereby allowing the energy dissipation and power generation panel to rotate backward to its lowest position. This state is the flood control state. Of course, it is also possible to directly retract the rigid telescopic rods without rotating the rotating shaft, but the energy dissipation and power generation panel cannot rotate to its lowest position.

[0023] The process of returning to the initial state from the flood discharge state: The first translation push-pull system and the second translation push-pull system do not operate. The rigid telescopic rod on the telescopic rotation system extends, and at the same time, the support rotation axis rotates clockwise and counterclockwise. At this time, the reinforced concrete wall rotates around the second axis and the first axis to cooperate with the overall rotation, thereby realizing the forward rotation of the energy dissipation and power generation panel to the upright state. At this time, the state is restored to the initial state.

[0024] In summary, the combined energy dissipation and power generation device installed on the spillway face not only solves the energy dissipation problem of traditional spillway faces but also generates electricity, thus saving energy. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] For examples, please refer to Figures 1-14This embodiment provides a combined energy dissipation and power generation device installed on the surface of an overflow dam, including a rotary and translational dual-purpose energy dissipation and power generation device 1, a left energy dissipation plate 3, and a right energy dissipation plate 2. The left and right energy dissipation plates are arranged on both sides of the energy dissipation and power generation device 1. The rotary and translational dual-purpose energy dissipation and power generation device includes an energy dissipation and power generation plate 1-1 and a rotary and translational combined system 1-2. The energy dissipation and power generation plate includes a wall 1-1a, on which multiple water passage holes 1-1b are provided. A door 1-1c and a hydroelectric power generation device 1-3 are arranged in the water passage holes. The hydroelectric power generation device is located inside the door, where the inside of the door refers to the side of the door facing away from the water flow direction. The rotary and translational system includes a first translational push-pull system 1-2a, a second translational push-pull system 1-2c, and a telescopic rotary system 1-2b. The telescopic rotary system is located between the first translational push-pull system and the second translational push-pull system, preferably in the middle position. The first translational push-pull system... The push-pull system 1-2a includes a first push-pull support 1-2aa, a first translational push-pull telescopic rod 1-2ab, and a first shaft 1-2ac disposed at the power output end of the first translational push-pull telescopic rod. A first rotary power device capable of driving the first translational push-pull telescopic rod to rotate is disposed within the first push-pull support. A groove 1-1d cooperating with the first shaft is disposed on the back side of the wall. Here, the back side of the wall refers to the side of the wall facing away from the water flow direction. The second translational push-pull system has the same structure as the first translational push-pull system and will not be described again here. The telescopic rotation system includes a rotary support 1-2ba, a rigid telescopic rod 1-2bc, and a second shaft 1-2bd. A second rotary power device capable of driving the rigid telescopic rod to rotate is disposed within the rotary support. A groove cooperating with the second shaft is disposed on the back side of the wall. In this embodiment, both the translational push-pull rod and the rigid telescopic rod can be electric telescopic rods or electric hydraulic rods.

[0043] In actual manufacturing, the power output end of the second rotary power device can be directly connected to the rigid telescopic rod, or a rotating shaft 1-2bb can be installed on it, with the rigid telescopic rod connected to the rotating shaft.

[0044] A water inlet is formed between the left and right energy dissipation plates. When the energy dissipation and power generation plate moves forward to its limit position, the wall can block the water inlet. When the energy dissipation and power generation plate moves backward to its limit position, there is a distance between the wall and the water inlet, allowing the water inlet to be open. In this embodiment, the left and right energy dissipation plates are preferably arranged symmetrically with respect to the wall. A left rotation power device 3-2 is provided on the side of the left energy dissipation plate away from the wall, and the left rotation power device is installed on the overflow dam body 7. The power output end of the left rotation power device is connected to the left energy dissipation plate. A right rotation power device 2-2 is provided on the side of the right energy dissipation plate away from the wall, and the right rotation power device is installed on the overflow dam body. The power output end of the right rotation power device is connected to the right energy dissipation plate. The power output end of the left rotation power device can be directly connected to the left energy dissipation plate or connected through the left rotation shaft 3-3. The power output end of the right rotation power device can be directly connected to the right energy dissipation plate or connected through the right rotation shaft 2-3. This is well known to those skilled in the art and will not be described in detail here.

[0045] The aforementioned combined energy dissipation and power generation device installed on the spillway face has at least the following functions when in use:

[0046] 1. Power Generation Function of the Device: The power generation function of this invention is mainly realized by the hydroelectric power generation devices 1-3 located on the rotary-translational dual-purpose energy dissipation power generation device 1. In this embodiment, multiple small hydroelectric power generation devices can be used to realize the power generation function. The hydroelectric power generation devices are located at the bottom of the water passage hole and work in conjunction with the door installed in the water passage hole to realize the corresponding power generation function. When water flows through the rotary-translational dual-purpose energy dissipation power generation device 1, the door opens, impacting the hydroelectric power generation device, and the kinetic potential energy of the water flow is converted into electrical energy to generate electricity; the generated electricity can be used for the real-time operation of the device or stored in the energy storage tank for later use. The hydroelectric power generation device can be divided into four levels in the longitudinal direction to adapt to power generation under different water levels. When there is no water flow, the door is closed, which provides a certain degree of protection for the power generation device and improves the durability of the device.

[0047] 2. Energy dissipation function of the device: The energy dissipation principle of this invention is to reduce the flow velocity of the upstream flow of the overflow dam by using energy dissipation plates. Figure 9 This is the initial state of the entire device. At this time, the center lines of the energy dissipation and power generation plate 1-1, the right energy dissipation plate 2, and the left energy dissipation plate 3 are on a straight line, all perpendicular to the direction of water flow. The water flows through the entire device and crashes back and forth in the middle of the device, consuming some of the kinetic energy of the water flow, thereby achieving energy dissipation.

[0048] As the water flow velocity increases, the operating state of the device can be adjusted, moving the energy dissipation and power generation plate backward. The main process involves the first translational push-pull system 1-2a's first translational push-pull telescopic rod 1-2ab retracting backward, causing the energy dissipation and power generation plate 1-1 to move backward. The second translational push-pull system 1-2c operates synchronously with the first translational push-pull system 1-2a, arranged symmetrically to prevent the energy dissipation and power generation plate 1-1 from shifting during the translation process. At this time, the rigid telescopic rod 1-2bc on the telescopic rotation system 1-2b retracts, and the rotating shaft 1-2bb mounted on the rotating support 1-2ba rotates clockwise, coordinating with the left and right translational push-pull systems. The final operating state of the device is as follows: Figure 11 state.

[0049] When the water flow velocity decreases, the energy dissipation and power generation plate 1-1 moves forward. The main process is that the first translational push-pull telescopic rod 1-2ab of the first translational push-pull system 1-2a extends forward, and the energy dissipation and power generation plate 1-1 moves forward. The second translational push-pull system 1-2c operates synchronously with the first translational push-pull system 1-2a. At this time, the rigid telescopic rod 1-2bc on the telescopic rotation system 1-2b extends, and the rotating shaft 1-2bb installed on the rotating support 1-2ba rotates counterclockwise, realizing the cooperation with the left and right translational push-pull systems. Finally, the device returns to its operating state. Figure 9 state.

[0050] 3. Flood discharge function of the device

[0051] The flood discharge function of this invention is mainly achieved when the upstream water level of the spillway is very high, and the inflow water level and velocity on the spillway surface are also very high. At this time, the water flow has a great impact on the overall device. In order to ensure that the overall device does not affect the flood discharge of the upstream flow, it is necessary to start the device from its initial state ( Figure 9 ) Operation to flood control state ( Figure 12 ).

[0052] The process from the initial state to the flood control state: The first translational push-pull system 1-2a and the second translational push-pull system 1-2c are not operating. The rigid telescopic rod 1-2bc on the telescopic rotation system 1-2b retracts, and at the same time, the rotating shaft 1-2bb rotates counterclockwise. At this time, the wall 1-1a rotates around the second shaft 1-2bd and the first shaft 1-2ac, thus coordinating with the overall rotation, thereby enabling the energy dissipation and power generation panel 1-1 to rotate backward to the lowest position. This state is the flood control state. Of course, it is also possible to directly retract the rigid telescopic rod without rotating the rotating shaft, but the energy dissipation and power generation panel cannot rotate to the lowest position.

[0053] The process of returning to the initial state from the flood discharge state: The first translational push-pull system 1-2a and the second translational push-pull system 1-2c do not operate. The rigid telescopic rod 1-2bc on the telescopic rotation system 1-2b extends. At the same time, the support rotation shaft 1-2bb rotates clockwise and counterclockwise. At this time, the reinforced concrete wall 1-1a rotates around the second axis 1-2bd and the first axis 1-2ac, thereby coordinating the overall rotation, and thus realizing the forward rotation of the energy dissipation and power generation panel 1-1 to the upright state. At this time, the state is restored to the initial state.

[0054] 4. Fish passage function of the device

[0055] As the overall device is continuously adjusted and transformed, it only remains in the initial state ( Figure 9 In the current state (rotational and translational dual-purpose energy dissipation and power generation device 1, right energy dissipation plate 2, and left energy dissipation plate 3), the center lines are aligned, and the device completely covers the overflow dam surface in the direction perpendicular to the water flow. At this time, fish cannot pass through the device. When the device begins to change direction, a channel for fish to pass through appears on the overflow dam surface, allowing fish to pass through. For example... Figure 13 As shown, the fish can swim back and forth in a staggered pattern in a channel without any devices to achieve the fish passage function of the device; as Figure 14 During flood discharge, the overflow dam has channels on both sides, allowing fish to flow freely.

[0056] In the above embodiments, the first, second, third, left, and right rotating power devices can all be motors. The water passage is preferably a gradient hole, with the area of ​​one end of the gradient hole near the inner side of the wall being smaller than the area of ​​the other end. This reduces the cross-sectional area of ​​the water flowing out of the gradient hole, increases the flow velocity, and thus improves the power generation effect. The door can be connected to the wall via a flexible rotating shaft. In its original state, the door is perpendicular to the water passage, blocking it. When water flows through the water passage and impacts the door, the flexible rotating shaft is squeezed by water pressure, causing the door to rotate and open the water passage. The door is preferably a double door to facilitate opening under water impact. In this case, the double door installed on the gradient section of the gradient hole can also use an existing spring-loaded rotating double door system.

[0057] The aforementioned dual-purpose rotation and translation energy dissipation and power generation device can be a reinforced concrete structure, mainly composed of an energy dissipation and power generation plate, a rotation and translation combined system, and a hydroelectric power generation device. The hydroelectric power generation device can be a small-scale device, allowing water to enter the gradual change orifice in a relatively stable flow state, reducing the scouring force of the water flow on the device. The energy dissipation and power generation plate can be [length missing]. ( —Width of the spillway face, in units ), width is The height is ( —Maximum water depth of the spillway.

[0058] In practical applications, an upstream velocity meter 4, a downstream velocity meter 5, and a water level gauge 6 can be installed on the spillway. The upstream velocity meter 4 is installed upstream of the spillway to facilitate monitoring changes in upstream flow velocity; the downstream velocity meter 5 is installed downstream of the spillway to facilitate monitoring changes in downstream flow velocity; and the water level gauge 6 is installed upstream of the spillway to facilitate monitoring upstream water level. Of course, the spillway wing walls 8 on both sides of the spillway should be installed close to the energy dissipation plate; these are well known to those skilled in the art and will not be elaborated upon here.

[0059] It should be noted that the above-mentioned rotation and translation combination system can also use other structures, as long as it can realize the functions of power generation, energy dissipation, flood discharge and fish passage relative to the spillway dam body. In addition, the rotation and translation dual-purpose energy dissipation and power generation device can also be used alone to realize the functions of energy dissipation and power generation.
