An ecological flow regulating device for a hydropower station based on photovoltaic power generation

Abstract

This invention discloses an ecological flow control device for hydropower stations based on photovoltaic power generation, which relates to the field of water conservancy and hydropower engineering technology. This photovoltaic-based ecological flow control device for hydropower stations achieves debris removal under different flow conditions by setting monitoring and positioning components. During operation, a first flow meter monitors the water flow velocity in the drainage pipe in real time and feeds the data back to the control module. The control module judges the degree of blockage in the filter bucket based on the flow velocity change. When the flow velocity drops to a set threshold, the positioning component opens, and the mounting plate descends due to the elasticity of a first spring, causing the second inclined end face gear ring to mesh with the first inclined end face gear ring. Then, the control module starts the drive motor to rotate the connecting rod and scraper for scraping and cleaning. This design fully utilizes water flow energy for normal cleaning, ensuring cleaning effectiveness under different flow conditions and guaranteeing the long-term stable operation of the ecological flow control system.

Description

Technical Field

[0001] This invention relates to the field of water conservancy and hydropower engineering technology, specifically to an ecological flow regulation device for hydropower stations based on photovoltaic power generation. Background Technology

[0002] Ecological flow refers to the volume and flow of water that needs to be retained or released within a river channel to maintain the basic functions and health of aquatic ecosystems such as rivers and lakes. However, the construction of hydropower stations and dams alters the natural hydrological state of rivers. When a hydropower station is in operation, a large amount of water is intercepted and diverted for power generation, leading to a sharp decrease in water volume, a plunge in water level, and even the drying up of the riverbed downstream of the dam, severely damaging the downstream ecological environment. Therefore, hydropower stations must continuously release a certain amount of ecological flow downstream.

[0003] Existing ecological flow control devices for photovoltaic power stations have the following problems: existing devices generally directly control the opening and closing of ecological water pipes to discharge water downstream and protect downstream river channels. Referring to the ecological water discharge pipe for centralized development of hydropower stations disclosed in patent application CN212358185U and the intelligent ecological flow control method and system for hydropower stations disclosed in patent application CN114876719B, the power generation is calculated by monitoring the ecological discharge flow and the output value of the turbine generator set, and then the valve is controlled to control the ecological discharge flow, and the water is discharged directly through the discharge pipe. However, in daily operation, the water flow of the hydropower station inevitably carries various debris, including aquatic plants, plastic waste and other suspended solids and bedloads. When the water flows downstream through the ecological flow pipe, these debris will enter the pipe with the water flow and deposit, entangle or jam at bends, diameter changes, valve sealing surfaces or gate guide rails, etc., affecting the opening and closing accuracy of the control device, and even causing valve jamming, poor sealing and flow channel blockage.

[0004] However, existing devices using the above technology typically intercept debris by setting up a debris-blocking net. However, the debris-blocking net cannot adaptively clean itself according to the degree of debris accumulation. This results in high labor intensity, low efficiency, and difficulty in ensuring maintenance frequency in remote hydropower stations. Once debris accumulates and becomes overloaded, it can easily cause the debris-blocking net to become clogged, leading to poor flow or even equipment jamming, which seriously affects the operational stability of the ecological flow control system. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an ecological flow control device for hydropower stations based on photovoltaic power generation. This solves the problems of existing ecological control devices being unable to adaptively clean according to the degree of debris accumulation, resulting in high labor intensity, low efficiency, and difficulty in ensuring maintenance frequency in remote hydropower stations.

[0016] Beneficial effects This invention provides an ecological flow regulation device for hydropower stations based on photovoltaic power generation. Compared with existing technologies, it has the following advantages: 1. This photovoltaic-powered hydropower station ecological flow control device achieves flexible debris removal under different flow conditions by setting up monitoring, positioning, and limiting components. During operation, the first flow meter monitors the water flow velocity in the drainage pipe in real time and feeds the data back to the control module. The control module autonomously judges the degree of blockage in the filter bucket based on the flow velocity change. When the flow velocity drops to a set threshold, the positioning component opens, and the elastic force of the first spring causes the mounting plate to descend, allowing the second inclined end face gear ring to mesh with the first inclined end face gear ring. Then, the control module starts the drive motor to drive the connecting rod to rotate. The meshing of the second and first inclined end face gear rings drives the drive shaft and scraper to rotate, scraping away the debris accumulated on the right side of the filter bucket. This design makes full use of water flow energy for normal cleaning, and only activates the drive motor when needed, effectively reducing system energy consumption while ensuring the cleaning effect under different flow conditions. This ensures the long-term stable operation of the ecological flow control system and is particularly suitable for remote hydropower stations and other places where maintenance is inconvenient.

[0017] 2. This photovoltaic-based hydropower station ecological flow control device, through the installation of an impeller, scraper, and cleaning arc plate, can clean debris on the right side of the filter bucket using water flow. When the water flow velocity in the ecological flow pipe is high, the water flow impacts the impeller to rotate, driving the scraper and cleaning arc plate to rotate automatically, continuously scraping away debris on the right side of the filter bucket. This design achieves adaptive online cleaning of the filter bucket. This design makes full use of water flow energy for normal cleaning, avoiding problems such as poor flow and equipment jamming caused by debris accumulation, and avoiding filter bucket blockage and control failure caused by debris accumulation.

[0018] 3. This photovoltaic-based hydropower station ecological flow control device achieves centralized collection of debris by setting up a storage bin and an arc-shaped filter plate. During use, the debris scraped off by the arc plate is carried by the water flow into the feed trough and then into the storage bin. The water then flows back to the ecological flow pipe after being filtered by the arc-shaped filter plate, while the debris is intercepted by the arc-shaped filter plate in the storage bin. When it is necessary to clean the debris, the bolts can be removed to remove the entire storage bin and open it for cleaning. This design achieves centralized collection and convenient cleaning of debris and has good practicality. Attached Figure Description

Furthermore, the flow rate of the water in the ecological flow pipe 1 can be monitored by the first flow meter 34, and the flow rate data will then be fed back to the control module 312 so that the control module 312 can determine the blockage of the filter hopper 310. When the water flow rate is too low to be driven by the impeller 36 to drive the scraper 311 to clean and scrape off the debris, causing the filter hopper 310 to be blocked by debris, the second inclined end face gear ring 315 will be activated to drive the first inclined end face gear ring 314 to rotate the scraper 311 to scrape off the debris on the right side of the filter hopper 310. The detection end of the second flow meter 35 penetrates the interior of the drain pipe 6 and extends into the interior of the ecological flow pipe 1. The flow rate in the drain pipe 6 can be monitored by the second flow meter 35, which makes it convenient for the control module 312 to determine the opening and closing size of the partition mechanism 2.

[0028] The isolation mechanism 2 includes an isolation valve plate 24 disposed on the left side inside the ecological flow pipe 1 for controlling the water flow rate inside the ecological flow pipe 1. A rear seal 21 is fixedly installed on the left end of the rear side of the ecological flow pipe 1, and a front seal 23 is fixedly installed on the left end of the front side of the ecological flow pipe 1. A valve motor 22 for driving the isolation valve plate 24 to rotate is fixedly installed at the front end of the front seal 23. The rear end of the rod of the isolation valve plate 24 penetrates the interior of the ecological flow pipe 1 and is rotatably installed inside the rear seal 21. The front end of the rod of the isolation valve plate 24 penetrates the interior of the ecological flow pipe 1 and is rotatably installed at the output end of the valve motor 22. The connection between the rod of the isolation valve plate 24 and the ecological flow pipe 1 is sealed with a sealed bearing. The valve motor 22 can drive the isolation valve plate 24 to rotate to control the water flow rate inside the ecological flow pipe 1.

[0029] By setting up monitoring, positioning, and limiting components, flexible debris removal under different flow conditions is achieved. During use, the first flow meter 34 monitors the water flow velocity in the drain pipe 6 in real time and feeds the data back to the control module 312. The control module 312 autonomously judges the degree of blockage of the filter hopper 310 based on the flow velocity change. When the flow velocity drops to a set threshold, the positioning component is opened, and the elastic force of the first spring 33 causes the mounting plate 320 to drop, allowing the second inclined end face gear ring 315 to mesh with the first inclined end face gear ring 314. Then, the control module 312... 2. The drive motor 321 is started to drive the connecting rod 319 to rotate. The second inclined end face gear ring 315 meshes with the first inclined end face gear ring 314 to drive the shaft rod 37 and scraper 311 to rotate, scraping and cleaning the debris accumulated on the right side of the filter hopper 310. This design makes full use of water flow energy for normal cleaning, and only activates the drive motor 321 when needed, which effectively reduces system energy consumption. At the same time, it ensures the cleaning effect under different flow conditions and ensures the long-term stable operation of the ecological flow control system. It is especially suitable for remote hydropower stations and other places where maintenance is inconvenient.

[0030] The second embodiment differs from the first embodiment in that: the cleaning assembly includes an impeller 36 fixedly installed at the right end of the shaft 37 to drive the shaft 37 to rotate; a scraper 311 fixedly installed at the right end of the shaft 37 to scrape off debris from the right side of the filter hopper 310; a cleaning arc plate 313 fixedly installed at the end of the scraper 311 away from the shaft 37 to scrape debris into the storage mechanism 4; and a replaceable blade made of SK2 high carbon steel is provided on the inner side of the cleaning arc plate 313 to cut tangled aquatic plants and other debris, which is convenient and quick; a support frame 39 fixedly installed inside the ecological flow pipe 1 to improve the stability of the shaft 37 when rotating; the left end of the shaft 37 passes through the inner side of the support frame 39 and is fixedly installed on the right side of the impeller 36; the right end of the shaft 37 passes through the left side of the filter hopper 310 and is fixedly installed on the left side of the scraper 311; the left side of the scraper 311 is close to the right side of the filter hopper 310; and the left side of the cleaning arc plate 313 is close to the right side of the support frame 39.

[0031] By setting up an impeller 36, scraper 311, and cleaning arc plate 313, the water flow can clean the debris on the right side of the filter bucket 310. When the water flow velocity in the ecological flow pipe 1 is high, the water flow impacts the impeller 36 to rotate, driving the scraper 311 and cleaning arc plate 313 to rotate automatically, continuously scraping away the debris on the right side of the filter bucket 310. This design realizes the adaptive online cleaning of the filter bucket 310. This design makes full use of water flow energy for normal cleaning, avoiding the problems of poor flow and equipment jamming caused by debris accumulation, and avoiding the blockage and control failure of the filter bucket 310 caused by debris accumulation.

[0032] The third embodiment differs from the second embodiment in that: the storage mechanism 4 includes a mounting frame 41 bolted to the front and rear sides of the ecological flow pipe 1. A storage box 42 for storing miscellaneous items is bolted inside the mounting frame 41, facilitating disassembly and cleaning of the internal debris. A feed chute 410 is provided at the right end of both the front and rear sides of the ecological flow pipe 1, and a side groove 44 for draining water into the ecological flow pipe 1 is provided at the left end of both sides. A sealing gasket is provided inside the side groove 44 to improve the sealing effect between the side groove 44 and the first sealing frame 45. The storage box 42... A slot 46 is provided at the left end of the side near the ecological flow pipe 1. An arc-shaped filter plate 43 for filtering out impurities and storing them in the storage box 42 is installed inside the slot 46 by bolts. A first sealing frame 45 is fixedly installed on the side of the slot 46 near the ecological flow pipe 1. A second sealing frame 48 is fixedly installed on the right end of the storage box 42 near the ecological flow pipe 1. A rubber pad is provided on the outside of the second sealing frame 48 to improve the sealing performance of the second sealing frame 48 and the sealing groove 49. A connecting groove 47 is provided at the right end of the storage box 42 near the ecological flow pipe 1. Sealing grooves 49 are provided at the right ends of both the front and rear sides of the ecological flow pipe 1.

[0033] The second sealing frame 48 is close to the inner side of the sealing groove 49 on the side near the ecological flow pipe 1. The first sealing frame 45 is close to the ecological flow pipe 1 on the side that penetrates the interior of the side groove 44 and extends into the interior of the ecological flow pipe 1. Debris will flow through the feed trough 410 and the connecting groove 47 into the storage box 42 for storage. The outer side of the first sealing frame 45 is close to the inner side of the side groove 44. Water will flow back into the interior of the ecological flow pipe 1 through the arc-shaped filter plate 43 and the guide of the first sealing frame 45.

[0034] The energy storage mechanism 5 includes a connecting plate 52 fixedly installed on the right side of the front of the ecological flow pipe 1. A battery 51 for storing electrical energy is fixedly installed on the front of the connecting plate 52, and a shell is provided on the outside of the battery 51 to protect the battery 51 from impact damage. The input end of the battery 51 is electrically connected to a line 54, and the material of the line 54 is RVVP type shielded cable, which has strong weather resistance and is suitable for long-term outdoor use. One end of the line 54 is electrically connected to a photovoltaic panel 53 for directly converting solar radiation energy into DC power. The photovoltaic panel 53 is an existing device that directly converts solar radiation energy into DC power to power the device through the photovoltaic effect, which will not be described in detail here.

[0035] By setting up a storage bin 42 and an arc-shaped filter plate 43, the debris is collected centrally. When in use, the debris scraped off by the arc plate 313 is carried by the water flow into the feed trough 410 and then into the storage bin 42. The water then flows back to the ecological flow pipe 1 after being filtered by the arc-shaped filter plate 43, while the debris is intercepted by the arc-shaped filter plate 43 and stored in the storage bin 42. When it is necessary to clean the debris, the bolts can be removed to remove the entire storage bin 42 and open it for cleaning. This design achieves centralized collection and convenient cleaning of debris and is highly practical.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] In use, the operator installs the drain pipe 6 to the hydropower station pipeline and then connects and fixes the ecological flow pipe 1 to the discharge pipe. Simultaneously, the energy storage mechanism 5 is installed in a suitable location. Solar energy is converted into DC power by the photovoltaic panel 53 and stored in the battery 51 via the line 54, providing clean energy for the various electrical components of the device. When water flows through the ecological flow pipe 1, the second flow meter 35 monitors the water flow in the drain pipe 6 and sends feedback to the control module 312. Based on the water flow in the drain pipe 6, the valve motor 22 is activated, driving the isolation valve plate 24 to rotate and open the ecological flow pipe 1. Debris is filtered down by the filter hopper 310. When the water flow velocity in the ecological flow pipe 1 is high, the water impacts the impeller 36, causing it to rotate and drive the scraper 3... 11. The cleaning arc plate 313 rotates automatically, continuously scraping away debris on the right side of the filter hopper 310. The filter hopper 310 drives the cleaning arc plate 313 to scrape and cut the debris. The cut debris is carried by the water flow into the feed trough 410 and into the storage bin 42. Then, the water flows back to the ecological flow pipe 1 after being filtered by the arc-shaped filter plate 43, while the debris is intercepted in the storage bin 42 by the arc-shaped filter plate 43. At the same time, the first flow meter 34 monitors the water flow rate in the drain pipe 6 in real time and feeds the data back to the control module 312. The control module 312 autonomously judges the degree of blockage of the filter hopper 310 based on the flow rate change. When the flow rate drops to the set threshold, the telescopic rod 323 is activated to drive the rack plate 322 forward, which in turn drives the gear disk 324 to position the positioning plate 3. 25. Rotation causes the mounting plate 320 to leave the top surface of the latching block 339. When the latching block 339 releases its restraint on the mounting plate 320, the elastic force of the first spring 33 can push the mounting plate 320 down. Then, the mounting plate 320 will drive the second inclined end face gear ring 315 to descend and mesh with the first inclined end face gear ring 314. At the same time, the rack plate 322 will continue to move forward, contacting the abutment rod 346 and pushing forward. Then, the abutment rod 346 will drive the upper end of the rack plate 322 to move forward, causing the guide block 326 to move down. At the same time, the bottom end of the rack plate 322 will drive the crossbar 332 to move the positioning latching plate 334 backward through the first groove plate 331. The mounting plate 320 will be locked in place by the positioning groove 335 for restraint. At the same time, the mounting plate 320 will be located in the positioning frame 3. Within 36, the screw drive unit 343 can then be activated to move the slider 338 downwards, pressing the mounting plate 320 into position via the positioning frame 336. This prevents the meshing of the second inclined end face gear ring 315 and the first inclined end face gear ring 314 from loosening. Then, the control module 312 activates the drive motor 321 to rotate the connecting rod 319. The meshing of the second inclined end face gear ring 315 and the first inclined end face gear ring 314 drives the drive shaft 37 and scraper 311 to rotate, scraping away debris accumulated on the right side of the filter hopper 310. When the isolation valve plate 24 opens to a large angle and the water flow rate in the drain pipe 6 is fast, the telescopic rod 323 is activated to move the rack plate 322 backwards, causing the gear disc 324 to rotate and reposition the positioning plate 325.Simultaneously, the rack plate 322 and positioning plate 334 are reset via the second spring 330 and the damping reset slide rail 333. Then, the screw drive unit 343 is activated, causing the positioning frame 336 to move the mounting plate 320 upwards via the slider 338. At the same time, the mounting plate 320 pushes open the locking block 339 and enters the slot 342. Then, the elastic force of the third spring 341 resets the locking block 339, fixing the mounting plate 320 in place for future use.
