Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and hydropower generation, and in particular to a water conservancy and hydropower generation unit. Background Art

[0002] Hydropower is a renewable energy source with less impact on the environment. It has a power generation efficiency of over 90%, low power generation cost, fast power generation start-up, and can be completed within minutes. It is easy to adjust and has the lowest cost per unit of output power. In addition to providing cheap electricity, it also has the following advantages: controlling flooding, providing irrigation water, and improving river navigation. The relevant projects also improve the transportation, power supply and economy of the region, especially the development of tourism and aquaculture.

[0003] There are many existing technologies for hydropower generating units, such as:

[0004] Chinese patent publication number CN216447038U discloses a water conservancy and hydropower generator set, including a turbine, an upper mounting seat and a lower mounting seat, and also a one-way valve. The top and bottom of the turbine are respectively provided with an upper mounting seat and a lower mounting seat, and the upper mounting seat and the lower mounting seat both include an inner mounting plate, an outer mounting plate and a seismic isolation support. The inner mounting plate of the upper mounting seat is welded to the top of the turbine shell, and the inner mounting plate of the lower mounting seat is welded to the bottom of the turbine shell, and the seismic isolation support is respectively arranged between the corresponding inner mounting plate and the outer mounting plate. The overall water conservancy and hydropower generator set is stable and efficient in use, and can perform good shock-absorbing treatment on the turbine set for mechanical energy of water conservancy power generation, thereby greatly increasing the stability and safety of the dam building for long-term use, and has high practicality.

[0005] Chinese patent publication number CN112253354A discloses a water conservancy power generation equipment with a debris processing function, including a vertical mounting part and a base fixed at the lower part of the vertical mounting part for fixing the vertical mounting part, an interception component for separating water flow and debris is movably installed on the side of the vertical mounting part facing the water flow, and a water wheel component that rotates when the water flow passes is installed below the vertical mounting part; when the water flow passes through the interception component, the interception component is used to block the debris in the water flow, and at the same time, when the water flow passes through the water wheel component, the flow kinetic energy of the water flow is used to drive the water wheel component to rotate, and the water wheel component drives the generator set to rotate to cut the magnetic flux lines to generate electricity; at the same time, a transmission structure drives the interception component to continuously swing up and down and flip back and forth, and the separated, intercepted and fished debris is poured into the debris transfer mechanism, and the poured debris is transferred out of the water flow by the debris transfer mechanism, which has the function of integrating water purification and power generation.

[0006] At present, when the existing hydropower generation equipment is in use, the water flow drives the turbine to rotate, so that the turbine generates power to drive the generator to rotate and generate electricity. However, since there are often garbage objects floating in the river, when passing through the turbine, it is easy to cause the turbine to be entangled, affecting the rotation of the turbine and reducing the power generation efficiency. Now, a barrier fence is set at the end of the power generation equipment to block the garbage. At the same time, the operating personnel are required to salvage the garbage at the end of the barrier fence regularly, which is inconvenient. Moreover, when the aquatic plants in the water follow the flow of the water body, since some fish feed on the aquatic plants, it is easy to salvage all the aquatic plants when salvaging floating objects, thereby affecting the ecology.

[0007] In view of this, we propose a water conservancy and hydropower generation unit. Summary of the invention

[0009] To achieve the above-mentioned object, the present invention provides a water conservancy and hydroelectric power generation unit, comprising a machine body and a support fixing plate arranged on a side away from the end of the machine body, wherein the machine body is a hollow structure with an opening at the bottom, a power generation unit is arranged at the opening at the bottom of the machine body, and the power generation unit is symmetrically arranged, and water flows through the machine body to impact the turbine of the power generation unit to rotate and generate electricity, and a barrier fence is arranged at the end of the power generation unit, and the barrier fence is used to prevent floating objects from flowing into the power generation unit, and a collection tank is arranged above the barrier fence;

[0010] A power assembly is provided at the end of the barrier fence, and the power assembly rotates under the impact of the water flow. A garbage cleaning assembly is provided between the power assemblies, and the power assembly drives the garbage cleaning assembly to reciprocate in the vertical direction when rotating. When the garbage cleaning assembly moves from under the water flow to near the end of the collecting trough, the garbage floating on the water surface gathers inside the garbage cleaning assembly, and the garbage cleaning assembly automatically pushes the garbage to fall into the collecting trough for collection. A dividing assembly is provided at the bottom of the garbage cleaning assembly, and the dividing assembly is used to cut the aquatic plants floating in the middle of the water body, so that the aquatic plants flow to the downstream of the river in the form of multiple segments.

[0011] As a further improvement of the technical solution, symmetrical water-gathering plates are hinged on both sides of the body. By adjusting the angle of the water-gathering plates, the flowing water is gathered so that the water body is concentrated through the opening at the bottom of the body, thereby increasing the impact force of the water flow on the power generation group. A drainage trough is provided at the end of the water-gathering plate. When the water flow increases, the river water is drained through multiple channels through the drainage trough.

[0012] As a further improvement of the present technical solution, the power assembly includes a fixed frame arranged at the end of the body, a fan blade is rotatably provided at the center of the fixed frame, and the fan blade is driven to rotate when the water flow impacts the fan blade. The end of the fan blade passes through the fixed frame and is provided with a driving gear at the end. A symmetrical driven gear is provided on the inner side of the driving gear. When the driving gear rotates, it drives the driven gear to mesh and rotate, and a half gear is provided at the end of the driven gear.

[0013] As a further improvement of the present technical solution, the garbage cleaning assembly includes a gear rod arranged between the half gears, and a collecting frame is provided at the bottom of the gear rod. When the half gears rotate, the gear rod is driven to move in a vertical direction. When the gear rod drives the collecting frame to move away from the water flow direction, the collecting frame collects floating objects on the surface of the water flow.

[0014] As a further improvement of the present technical solution, a servo motor is provided at the bottom of the gear rod, a water-proof shell is provided outside the servo motor, the output end of the servo motor passes through the collecting frame and a screw is provided at the end, and when the output end of the servo motor drives the screw to rotate, a push plate provided on the surface of the screw reciprocates in a horizontal direction.

[0015] As a further improvement of the technical solution, through holes are opened at the bottom of the collection frame, and the through holes are arranged in an array. When the collection frame is away from the water flow, the water flows out through the through holes.

[0016] As a further improvement of the technical solution, symmetrical limiting rods are provided on both sides of the bottom of the machine body, and the collection frame moves on the surfaces of the limiting rods, and the moving direction of the collection frame is limited by the limiting rods.

[0018] As a further improvement of the technical solution, an elastic member is provided between the cutting knife and the fixed block, and when the collecting frame approaches the water body in a vertical direction, the cutting knife cuts the aquatic plants attached to the surface of the barrier.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the water conservancy and hydropower generating unit, when the water flow hits the fan blades, the fan blades drive the driving gear to rotate, and the driven gears on both sides of the driving gear mesh and rotate. Since a half gear is provided at the end of the driven gear, when the driven gear rotates, the half gear drives the gear rod to reciprocate in the vertical direction. Since a barrier fence is provided at the end of the power generation group, the garbage floating on the water surface is blocked by the barrier fence to prevent the garbage from flowing to the power generation group and winding around the turbine group. When the gear rod moves away from the water surface, the gear rod drives the collection frame to move upward, and the collection frame automatically collects the garbage floating on the water surface, thereby reducing the labor intensity of the operators, facilitating the real-time collection of garbage, and improving the garbage collection efficiency.

[0021] 2. In the water conservancy and hydropower generating unit, the collecting frame drives the cutting knife to move downward in the vertical direction. An elastic part is provided between the cutting knife and the fixed block. When the cutting knife rotates and cuts, the elastic part limits the cutting knife, thereby improving the cutting force of the cutting knife. During the downward movement of the cutting knife, the mechanical energy cutting force on the water plants adsorbed on the surface of the barrier fence is applied, so that the water plants are divided into multiple sections. The water plants divided into multiple sections will not entangle the turbine of the power generating unit. The cut water plants flow downstream through the barrier fence to feed the fish downstream, thereby protecting the ecological environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Hydropower is a renewable energy source with less impact on the environment. Its power generation efficiency is as high as over 90%. It has low power generation cost, fast power generation start-up, can complete power generation within a few minutes, is easy to adjust, and has the lowest cost per unit of output power. When the existing hydropower generation equipment is in use, the turbine is driven by water flow to rotate, so that the turbine generates power to drive the generator to rotate and generate electricity. However, since there are often garbage objects floating in the river, when passing through the turbine, it is easy to cause the turbine to be entangled, affecting the rotation of the turbine and reducing the power generation efficiency. At present, a barrier fence is set at the end of the power generation equipment to block the garbage. At the same time, the operating personnel are required to regularly salvage the garbage at the end of the barrier fence, which is inconvenient. Moreover, when the aquatic plants in the water follow the flow of the water body, since some fish feed on the aquatic plants, it is easy to salvage all the aquatic plants when salvaging the floating objects, thereby affecting the ecology.

[0037] The purpose of this embodiment is to provide a water conservancy and hydropower generation unit, referring to Figure 1-Figure 7 As shown, it includes a body 100 and a supporting fixing plate 104 arranged at a side away from the end of the body 100. The body 100 is a hollow structure with an opening at the bottom. A power generation group 101 is arranged at the opening at the bottom of the body 100. The power generation group 101 is symmetrically arranged. Water flows through the body 100 to impact the turbine of the power generation group 101 to rotate and generate electricity. A barrier fence 102 is arranged at the end of the power generation group 101. The barrier fence 102 is used to prevent floating objects from flowing into the power generation group 101. A collection tank 103 is arranged above the barrier fence 102.

[0038] A power assembly 300 is provided at the end of the barrier fence 102, and the power assembly 300 rotates under the impact of the water flow. A garbage cleaning assembly 400 is provided between the power assemblies 300. When the power assembly 300 rotates, it drives the garbage cleaning assembly 400 to reciprocate in the vertical direction. When the garbage cleaning assembly 400 moves from under the water flow to near the end of the collecting trough 103, the garbage floating on the water surface gathers inside the garbage cleaning assembly 400, and the garbage cleaning assembly 400 automatically pushes the garbage to drop into the collecting trough 103 for collection. A splitting assembly 500 is provided at the bottom of the garbage cleaning assembly 400, and the splitting assembly 500 is used to cut the aquatic plants floating in the middle of the water body, so that the aquatic plants flow to the downstream of the river in the form of multiple segments.

[0039] The improvement of this embodiment is that when the water flow hits the fan blade 301, the fan blade 301 drives the driving gear 302 to rotate, and the driven gears 303 on both sides of the driving gear 302 engage and rotate. Since a half gear 304 is provided at the end of the driven gear 303, when the driven gear 303 rotates, the half gear 304 drives the gear rod 401 to reciprocate in the vertical direction. Since a barrier fence 102 is provided at the end of the power generation group 101, the barrier fence 102 is used to block the garbage floating on the water surface to prevent the garbage from flowing to the power generation group 101 and winding around the turbine group. When the gear rod 401 moves away from the surface of the water body, the gear rod 401 drives the collecting frame 402 to move upward, and the collecting frame 402 automatically collects the garbage floating on the surface of the water body, thereby reducing the labor intensity of the operators, facilitating the real-time collection of garbage, and improving the garbage collection efficiency.

[0040] In water conservancy projects, when the water flow in a river is small, the impact force of the river on the turbine of the generator set 101 is small, so in order to improve the power generation efficiency of the generator set, symmetrical water-collecting plates 200 are hinged on both sides of the body 100. By adjusting the angle of the water-collecting plates 200, the flowing water is gathered, so that the water body is concentrated through the bottom opening of the body 100, thereby increasing the impact force of the water flow on the generator set 101. A drainage trough 201 is opened at the end of the water-collecting plate 200. When the water flow increases, the river water is drained through multiple channels through the drainage trough 201, and the river is blocked by the generator set 101 to make the water in the river converge. The converged water flow has a large water potential difference, and when it flows through the body 100, it strengthens the impact force on the turbine of the generator set 101, thereby increasing the rotation speed of the turbine and improving the power generation efficiency of the generator set 101.

[0041] When the water flows, in order to facilitate the automatic collection of garbage on the surface of the water flow, the power component 300 includes a fixed frame arranged at the end of the body 100, and a fan blade 301 is rotatably arranged at the center of the fixed frame. When the water flow hits the fan blade 301, it is driven to rotate. The end of the fan blade 301 passes through the fixed frame and is provided with a driving gear 302 at the end. A symmetrical driven gear 303 is provided on the inner side of the driving gear 302. When the driving gear 302 rotates, it drives the driven gear 303 to mesh and rotate. The ends of the driven gears 303 are all provided with half gears 304. The garbage cleaning component 400 includes a gear rod 401 arranged between the half gears 304. A collecting frame 402 is provided at the bottom of the gear rod 401. When the half gear 304 rotates, it drives the gear rod 401 to move in a vertical direction. When the gear rod 401 drives the collecting frame 402 to move away from the water flow direction, the collecting frame 402 Floating objects on the surface of the water flow are collected. When the water flow impacts the fan blades 301, the fan blades 301 drive the driving gear 302 to rotate, and the driven gears 303 on both sides of the driving gear 302 mesh and rotate. Since a half gear 304 is provided at the end of the driven gear 303, when the driven gear 303 rotates, the half gear 304 drives the gear rod 401 to reciprocate in the vertical direction. Since a barrier fence 102 is provided at the end of the power generation group 101, the barrier fence 102 is used to block the garbage floating on the water surface to prevent the garbage from flowing to the power generation group 101 and winding around the turbine group. When the gear rod 401 moves away from the surface of the water body, the gear rod 401 drives the collecting frame 402 to move upward, and the collecting frame 402 collects the garbage floating on the surface of the water body, thereby reducing the labor intensity of the operators, facilitating the real-time collection of garbage, and improving the garbage collection efficiency.

[0042] Taking into account that when the garbage collection is completed, since most of the floating objects are irregular in shape, in order to enable the garbage to be quickly collected into the collection tank 103, a servo motor is provided at the bottom of the gear rod 401, and a waterproof shell is provided on the outside of the servo motor. The output end of the servo motor passes through the collection frame 402 and a screw 404 is provided at the end. When the output end of the servo motor drives the screw 404 to rotate, the push plate 405 provided on the surface of the screw 404 reciprocates in the horizontal direction. When the collection frame 402 moves to the end of the collection tank 103, the servo motor drives the screw 404 to rotate, and the push plate 405 provided on the surface of the screw 404 moves in the horizontal direction. The push plate 405 pushes the garbage on the surface of the collection frame 402, so that the garbage is away from the surface of the collection frame 402 and falls into the collection tank 103, which is convenient for collecting floating garbage.

[0043] During the downward movement of the push plate 405 in the vertical direction, in order to reduce the resistance of the water to the push plate 405, a through hole 403 is opened at the bottom of the collecting frame 402, and the through holes 403 are arranged in an array. When the collecting frame 402 is away from the water flow, the water flows out through the through holes 403. By opening a plurality of through holes 403 on the surface of the collecting frame 402, during the downward movement of the collecting frame 402, the water can quickly enter the collecting frame 402 through the through holes 403, thereby reducing the resistance of the water to the bottom of the collecting frame 402, making it easier for the collecting frame 402 to automatically reciprocate to collect garbage floating on the water surface, thereby improving the collection efficiency of garbage floating on the water surface.

[0044] During the movement of the collecting frame 402, in order to avoid the displacement direction of the collecting frame 402, symmetrical limit rods 105 are provided on both sides of the bottom of the body 100, and the collecting frame 402 moves on the surface of the limit rods 105, and the moving direction of the collecting frame 402 is limited by the limit rods 105. When the gear rod 401 drives the collecting frame 402 to move in the vertical direction, the two sides of the collecting frame 402 slide on the outer wall of the limit rod 105, and its moving path is limited by the limit rods 105, thereby avoiding the position deviation of the collecting frame 402 during the movement, and ensuring the efficiency of automatic cleaning of floating garbage.

[0045] Since the barrier fence 102 is provided at the end of the power generation group 101, in addition to the garbage floating on the water surface, there are also water plants floating in the water flow. When the collecting frame 402 moves up to collect the floating garbage, the water plants follow the water flow to the end of the barrier fence 102. Since the water plants are tough, during the downward movement of the collecting frame 402, the water plants will be pushed by the bottom of the collecting frame 402, so that the water trough is accumulated at the bottom of the collecting frame 402, resulting in the bottom of the barrier fence 102 being blocked, affecting the impact force of the water flow on the turbine group of the power generation group 101. Therefore, the dividing component 500 includes a fixed block set at the bottom of the collecting frame 402, and the fixed blocks are arranged in a linear array. Support rods 501 are provided between the fixed blocks. A cutting knife 502 is provided on the surface of the support rod 501. The cutting knife 502 rotates on the surface of the support rod 501. When the collecting frame 402 moves up in the vertical direction, the water plants on the water body surface and floating in the middle of the water body are collected by the collecting frame 402. The collecting frame 402 moves to When the collecting trough 103 reaches the end, the garbage and aquatic plants are pushed into the collecting trough 103 by the push plate 405 for collection. When the floating objects are cleaned up, the floating garbage and aquatic plants are concentrated and blocked by the barrier fence 102 while the collecting frame 402 is away from the water flow. When the collecting frame 402 moves downward, the bottom of the collecting frame 402 presses the garbage floating on the surface of the water flow. At this time, the floating garbage moves irregularly due to the pressing pressure of the bottom of the collecting frame 402 and drills out from the bottom of the collecting frame 402. Due to the large buoyancy of the floating garbage, the floating objects float on the surface of the water flow again. At the same time, the collecting frame 402 drives the cutting knife 502 to move downward in the vertical direction, and the aquatic plants adsorbed on the surface of the barrier fence 102 are cut by the cutting force of the cutting knife 502, so that the aquatic plants are divided into multiple sections. The aquatic plants divided into multiple sections will not entangle the turbine of the power generation group 101, and thus flow downstream through the barrier fence 102, so that the aquatic plants feed the fish downstream, thereby protecting the ecological environment.

[0046] Taking into account that the thickness of the rhizomes of aquatic plants vary during their growth, in order to facilitate the rapid cutting of the aquatic plants, an elastic member 503 is provided between the cutting knife 502 and the fixed block. When the collecting frame 402 approaches the water body in the vertical direction, the cutting knife 502 cuts the aquatic plants attached to the surface of the barrier fence 102. In the process of the collecting frame 402 driving the cutting knife 502 to move downward, the cutting knife 502 squeezes and cuts the aquatic plants attached to the surface of the barrier fence 102. In order to increase the cutting force of the cutting knife 502, an elastic member 503 is provided between the cutting knife 502 and the fixed block. When the cutting knife 502 rotates and cuts, the elastic member 503 limits the cutting knife 502, thereby increasing the cutting force of the cutting knife 502 and facilitating the rapid cutting and segmentation of aquatic plants with thicker rhizomes.

[0047] In summary, the working principle of the present invention is as follows: the body 100 is fixed by the support fixing plate 104, and the water flow impacts the turbine of the power generation group 101, so that the turbine drives the generator shaft to rotate to generate electricity. By setting a barrier fence 102 at the end of the power generation group 101, the garbage floating in the water flow and the aquatic plants in the water are blocked to prevent the garbage from adhering to the surface of the power generation group 101 and affecting the power generation efficiency. At the same time, during the flow of water, when the water flow impacts the fan blade 301, the fan blade 301 drives the driving gear 302 to rotate, and the driven gears 303 on both sides of the driving gear 302 engage and rotate. Since a half gear 304 is provided at the end of the driven gear 303, when the driven gear 303 rotates, the half gear 304 drives the gear rod 401 to reciprocate in the vertical direction. Since a barrier fence 102 is provided at the end of the power generation group 101, the garbage floating on the water surface is blocked by the barrier fence 102 to prevent the garbage from flowing to the power generation group 101 and winding around the turbine group. When the gear rod 40 When the collecting frame 402 moves away from the surface of the water body, the gear rod 401 drives the collecting frame 402 to move upward, and the collecting frame 402 automatically collects the garbage floating on the surface of the water body, thereby reducing the labor intensity of the operators, facilitating the real-time collection of garbage, and improving the collection efficiency of garbage. When the collecting frame 402 moves downward, the bottom of the collecting frame 402 presses the garbage floating on the surface of the water flow. At this time, the floating garbage moves irregularly due to the pressing force of the bottom of the collecting frame 402, and drills out from the bottom of the collecting frame 402. Due to the large buoyancy of the floating garbage, the floating objects float on the surface of the water flow again. At the same time, the collecting frame 402 drives the cutting knife 502 to move downward in the vertical direction, and the water grass adsorbed on the surface of the barrier fence 102 is cut by the cutting force of the cutting knife 502, so that the water grass is divided into multiple sections. The water grass divided into multiple sections will not entangle the turbine of the power generation group 101, and thus flow downstream through the barrier fence 102, so that the water grass feeds the fish downstream, which is convenient for maintaining the balance of the ecological environment.
