Farmers open the water valve to irrigate the fields. However, when farmers apply pesticides, for the sake of convenience, they will directly take water from the water diversion channel, and farmers often casually discard pesticide bags into the water diversion channel. In addition, since most water diversion channels are open-air, other garbage such as floating weeds and withered leaves often floats in the water diversion channel. Among them, after long-term use of the water diversion channel, silt will also precipitate at the bottom of the water diversion channel. Therefore, the water diversion channel often becomes blocked due to these garbage and silt.

Detailed implementation manners

[0041] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0042] In the embodiment of the present invention, through a water diversion structure for water conservancy and hydropower projects, when using the water diversion channel 1 for agricultural irrigation, generally, water in the river needs to be introduced into the water diversion channel 1, and a water valve is installed on the water diversion channel 1. Farmers open the water valve to irrigate the fields. However, when farmers spray pesticides, for the sake of convenience, they will directly take water from the water diversion channel 1, and farmers often discard pesticide bags into the water diversion channel 1 at will. In addition, since most of the water diversion channels 1 are open-air, there are often floating weeds, dead leaves and other garbage in the water diversion channel 1. Among them, after the water diversion channel 1 is used for a long time, silt will also precipitate at the bottom of the water diversion channel 1. Therefore, the water diversion channel 1 often has a blockage phenomenon due to these garbage and silt.

[0043] To solve the above technical problems, the overall concept of the present invention is as follows: By providing a cleaning unit 2 and a power generation unit 3 on the water diversion canal 1, when water flows through the water diversion canal 1, the water in the canal flows through the power generation unit 3, thereby driving the power generation unit 3 to move and generate electricity. While generating electricity, the power generation unit 3 provides power for the cleaning unit 2, so that the power generation unit 3 drives the cleaning unit 2 to reciprocate in the water diversion canal 1, thereby achieving the effect of cleaning the garbage and silt in the water diversion canal 1, so as to avoid the phenomenon of blockage of the water diversion canal 1 due to garbage and sedimented silt.

[0044] To better understand the above technical solution, the following will specifically describe the above technical solution in conjunction with the accompanying drawings of the specification and specific embodiments.

[0045] The present invention provides a water diversion structure for water conservancy and hydropower projects, including a water diversion canal 1, and further including:

[0046] A cleaning unit 2, the cleaning unit 2 is arranged in the water diversion canal 1, and the cleaning unit 2 cleans the floating garbage and sedimented silt in the water diversion canal 1;

[0047] A power generation unit 3, the power generation unit 3 is located on one side of the cleaning unit 2, and the power generation unit 3 provides power for the cleaning unit 2.

[0048] When using the water diversion canal 1 for agricultural irrigation, it is generally necessary to introduce water from the river into the water diversion canal 1, and install a water valve on the water diversion canal 1. Farmers open the water valve to irrigate the fields. However, when farmers apply pesticides, for the sake of convenience, they will directly take water from the water diversion canal 1, and farmers often discard the pesticide bags into the water diversion canal 1 at will. In addition, since most of the water diversion canals 1 are open-air, there are often other garbage such as floating weeds and withered leaves in the water diversion canal 1. After a long time of use of the water diversion canal 1, silt will also precipitate at the bottom of the water diversion canal 1. Therefore, the water diversion canal 1 often becomes blocked due to these garbage and silt.

[0049] Therefore, the present invention provides a cleaning unit 2 and a power generation unit 3 on the water diversion canal 1. When water flows through the water diversion canal 1, the water in the water diversion canal 1 flows through the power generation unit 3, thereby driving the power generation unit 3 to move and generate electricity. While generating electricity, the power generation unit 3 provides power for the cleaning unit 2, so that the power generation unit 3 drives the cleaning unit 2 to reciprocate in the water diversion canal 1, thereby achieving the effect of cleaning the garbage and silt in the water diversion canal 1, so as to avoid the phenomenon of blockage of the water diversion canal 1 due to garbage and sedimented silt.

[0050] As a specific embodiment of the present invention, the cleaning unit 2 includes:

[0051] A fixing frame 21, the fixing frame 21 is arranged on the water diversion canal 1;

[0052] A reciprocating lead screw 22 is provided on a fixed frame 21.

[0053] A scraper 23 is provided on the reciprocating lead screw 22. A first wire mesh 231 is provided on the scraper 23. The scraper 23 is used to remove floating garbage and deposited silt in the diversion channel 1.

[0054] As a specific embodiment of the present invention, the power generation unit 3 includes:

[0055] A housing 31 is provided on the diversion channel 1.

[0056] A first rotating shaft 32 is located inside the housing 31 and is rotatably connected to the housing 31.

[0057] Propeller blades 33 are provided on the first rotating shaft 32.

[0058] A filter plate 34 is provided on the housing 31.

[0059] A generator set 35 is provided outside the diversion channel 1 and is connected to the first rotating shaft 32.

[0060] An energy storage box 36 is located on one side of the generator set 35 and is connected to the generator set 35.

[0061] In the present invention, a housing 31 is fixedly connected inside the diversion channel 1. A first rotating shaft 32 is rotatably connected inside the housing 31. Propeller blades 33 are provided on the first rotating shaft 32. A filter plate 34 is fixedly connected to the housing 31. A generator set 35 is provided outside the diversion channel 1. The generator set 35 is connected to the first rotating shaft 32. An energy storage box 36 is provided on one side of the generator set 35 and is connected to the generator set 35. A fixed frame 21 is fixedly connected to the diversion channel 1. A reciprocating lead screw 22 is rotatably connected to the fixed frame 21. A scraper 23 is provided on the reciprocating lead screw 22. A first wire mesh 231 is fixedly connected to the side of the scraper 23 away from the bottom of the diversion channel 1.

[0062] When the field needs to be irrigated, the water in the river flows into the diversion canal 1, passes through the filter plate 34 and flows into the housing 31. Since a first rotating shaft 32 is rotatably connected in the housing 31 and propeller blades 33 are provided on the first rotating shaft 32, when the water flows through the housing 31, the water flow pushes the propeller blades 33 to drive the first rotating shaft 32 to rotate. The first rotating shaft 32 is connected to the generator set 35, and the first rotating shaft 32 causes the generator set 35 to generate electricity and store the electric energy in the energy storage box 36. On the one hand, the fields are often far from the residential housing areas, so most farmers need to ride electric vehicles to the fields. If the electric vehicles run out of power, the farmers can charge the electric vehicles through the energy storage box 36 to prevent the farmers from being unable to ride home due to the lack of power of the electric vehicles. On the other hand, during the autumn harvest, in order to rush to harvest the crops, the farmers often need to harvest the crops at night. The farmers can connect their self - carried lighting facilities to the energy storage box 36 to provide a certain amount of lighting for working in the fields at night. While the first rotating shaft 32 is connected to the generator set 35 to generate electricity, the first rotating shaft 32 is also connected to the reciprocating lead screw 22. Therefore, the rotation of the first rotating shaft 32 drives the reciprocating lead screw 22 to rotate together. Since a scraper 23 is provided on the reciprocating lead screw 22, the rotation of the reciprocating lead screw 22 drives the scraper 23 to reciprocate in the diversion canal 1. A first wire mesh 231 is fixedly connected above the scraper 23, so that while the first wire mesh 231 clears the floating garbage in the diversion canal 1, the water flow can smoothly flow through the scraper 23. The lower part of the scraper 23 scrapes the silt deposited at the bottom of the diversion canal 1, thereby preventing the diversion canal 1 from being blocked due to excessive garbage and deposited silt in the diversion canal 1.

[0063] As a specific embodiment of the present invention, a drain pipe 4 is provided on the diversion canal 1, and a second rotating shaft 41 is rotatably connected in the drain pipe 4, and a spiral blade 42 is fixedly connected to the second rotating shaft 41.

[0064] As a specific embodiment of the present invention, a mud guard 5 is fixedly connected to the diversion canal 1, and the mud guard 5 is rotatably connected to the reciprocating lead screw 22.

[0065] As a specific embodiment of the present invention, a collection box 6 is provided on the mud guard 5, and a second wire mesh 61 is provided on the collection box 6.

[0066] In the present invention, a drain pipe 4 is fixedly connected to the diversion canal 1. A second rotating shaft 41 is rotatably connected inside the drain pipe 4, and a spiral blade 42 is fixedly connected to the second rotating shaft 41. A mud guard 5 is fixedly connected inside the diversion canal 1. One end of the mud guard 5 is rotatably connected to a reciprocating lead screw 22. A collection box 6 is arranged above the mud guard 5, and the collection box 6 is slidably connected to the mud guard 5 through a buckle. A second wire mesh 61 is fixedly connected to the collection box 6. When the reciprocating lead screw 22 rotates to drive the scraper 23 to perform a reciprocating motion inside the diversion canal 1, the scraper 23 will push the floating garbage inside the diversion canal 1 into the collection box 6. At the same time, the second wire mesh 61 on the collection box 6 also facilitates the flow of water through the collection box 6. The second wire mesh 61 intercepts the garbage, thereby collecting the floating garbage. After the collection box 6 collects the garbage, it is slid off from the mud guard 5, and then the garbage inside the collection box 6 is processed; the sludge at the bottom of the diversion canal 1 is scraped off below the scraper 23. The scraper 23 continues to move forward, and the flowing water passes through the first wire mesh 231 above the scraper 23. The sludge deposited below the scraper 23 is pushed into the drain pipe 4. The flowing water pushes the second rotating shaft 41 inside the drain pipe 4 to drive the spiral blade 42 to rotate together, so as to quickly discharge the sludge into the field through the spiral blade 42. Since most of the sludge in the diversion canal 1 flows in from the river and has certain nutrients, directly discharging the sludge into the field can improve the soil quality of the field. Since the mud guard 5 is located on one side of the drain pipe 4, the mud guard 5 can block the sludge scraped by the scraper 23, so that the sludge moves into the drain pipe 4, thereby discharging the vast majority of the sludge.

[0067] As a specific implementation manner of the present invention, a mounting frame 7 is hinged to the scraper 23, and a mud stirrer 8 is rotatably connected to the mounting frame 7.

[0068] In the present invention, a mounting frame 7 is hinged to the scraper 23, and a mud stirrer 8 is rotatably connected to the mounting frame 7. Before the scraper 23 scrapes the sludge at the bottom of the diversion canal 1, the movement of the scraper 23 drives the water flow to drive the mud stirrer 8 to rotate. The mud stirrer 8 stirs the deposited sludge, reduces the resistance of the sludge to the scraper 23, and facilitates the scraper 23 to scrape the sludge.

[0069] As a specific implementation manner of the present invention, one end of the first rotating shaft 32 is rotatably connected to a docking shell 9. A pin 10 is arranged inside the docking shell 9. A circular groove 321 is formed on the first rotating shaft 32. The first rotating shaft 32 is rotatably connected to the reciprocating lead screw 22, and one end of the reciprocating lead screw 22 is located inside the circular groove 321. Through holes 221 for the pin 10 to pass through are formed on both the first rotating shaft 32 and the reciprocating lead screw 22.

[0070] Most of the garbage and sediment in the water diversion channel 1 take some time to generate. Continuously cleaning the water diversion channel 1 with the scraper 23 will affect the power generation of the power generation unit 3. Therefore, in the present invention, a docking shell 9 is rotatably connected to one end of the first rotating shaft 32 close to the reciprocating lead screw 22. A pin 10 is arranged in the docking shell 9. A circular groove 321 is formed on the first rotating shaft 32. The first rotating shaft 32 is rotatably connected to the reciprocating lead screw 22. One end of the reciprocating lead screw 22 is located in the circular groove 321. Through holes 221 for the pin 10 to pass through are formed on both the first rotating shaft 32 and the reciprocating lead screw 22. When it is necessary to clean the garbage and silt in the water diversion channel 1, the pin 10 is made to pass through the through hole 221, so that the first rotating shaft 32 and the reciprocating lead screw 22 are connected to each other. The first rotating shaft 32 drives the reciprocating lead screw 22 to rotate. After the cleaning is completed, the pin 10 is removed from the through hole 221 to disconnect the first rotating shaft 32 from the reciprocating lead screw 22, thereby achieving the effect of periodically cleaning the water diversion channel 1. Using the pin 10 to connect and disconnect the first rotating shaft 32 and the reciprocating lead screw 22 is economical and simple to operate.

[0071] As a specific embodiment of the present invention, a groove 91 is formed in the docking shell 9. A first spring 11 and a ball 12 are arranged in the groove 91. One end of the first spring 11 is fixedly connected to the inner surface of the groove 91. The other end of the first spring 11 is in contact with the ball 12. Two-thirds of the ball 12 is located in the groove 91. A card slot 101 matching the ball 12 is formed on the pin 10.

[0072] In the present invention, a groove 91 is formed in the docking shell 9. The first spring 11 and the ball 12 are arranged in the groove 91. A card slot 101 matching the ball 12 is formed on the pin 10. When the pin 10 is inserted into the docking shell 9 to connect the first rotating shaft 32 and the reciprocating lead screw 22, the pin 10 presses the ball 12 in the groove 91 to move into the groove 91. When the pin 10 moves to a certain position, the ball 12 is pressed into the card slot 101 by the elastic force of the first spring 11 to prevent the first rotating shaft 32 from driving the docking shell 9 to rotate and causing the pin 10 to fall off. Fixing the pin 10 by the ball 12 and the card slot 101 does not prevent the pin 10 from being pulled out. Since two-thirds of the ball 12 is located in the groove 91, the ball 12 will not fall out after the pin 10 is pulled out.

[0073] As a specific embodiment of the present invention, a cross-shaped sliding groove 322 is formed on the first rotating shaft 32. A second spring 13 and a cross-shaped slider 14 are arranged in the cross-shaped sliding groove 322. One end of the second spring 13 is fixedly connected to the cross-shaped sliding groove 322. The other end of the second spring 13 is fixedly connected to the cross-shaped slider 14. The cross-shaped slider 14 is fixedly connected to the propeller blade 33.

[0074] In the present invention, a cross chute 322 is provided on the first rotating shaft 32. A second spring 13 and a cross slider 14 are arranged in the cross chute 322. One end of the second spring 13 is fixedly connected to the inner wall of the cross chute 322, and the other end of the second spring 13 is fixedly connected to the cross slider 14. The cross slider 14 is fixedly connected to the propeller blade 33. When water flows into the housing 31, the filter plate 34 filters the garbage in the water flow. However, it is inevitable that some garbage will still enter the housing 31. If the garbage gets stuck in the propeller blade 33, at this time, the propeller blade 33 will be subjected to a greater impact force of the water flow due to being stuck by the garbage. When the impact force of the water flow is greater than the elastic force of the second spring 13, the water flow will push a single propeller blade 33 to drive the cross slider 14 to slide in the cross chute 322, so that the blocked propeller blade 33 moves radially relative to the other propeller blade 33, facilitating the garbage to flow out from the gap between the propeller blades 33, thereby enabling the water flow to wash out the stuck garbage from the housing 31, enabling the propeller blade 33 to rotate again. At the same time, the cross slider 14 prevents the propeller blade 33 from moving laterally relative to the first rotating shaft 32.

[0075] Working principle: When using the water diversion canal 1 for agricultural irrigation, generally, water in the river needs to be introduced into the water diversion canal 1. A water valve is installed on the water diversion canal 1, and farmers open the water valve to irrigate the fields. However, when farmers spray pesticides, for the sake of convenience, they will directly take water from the water diversion canal 1 and often casually discard the pesticide bags into the water diversion canal 1. In addition, since most of the water diversion canals 1 are open-air, there are often other garbage such as floating weeds and withered leaves in the water diversion canal 1. Among them, after the water diversion canal 1 has been used for a long time, silt will also accumulate at the bottom of the water diversion canal 1. Therefore, the water diversion canal 1 is often blocked due to these garbage and silt.

[0076] Therefore, in the present invention, a cleaning unit 2 and a power generation unit 3 are provided on the water diversion canal 1. After water flows through the water diversion canal 1, the water flow in the canal passes through the power generation unit 3, thereby driving the power generation unit 3 to move and generate electricity. While generating electricity, the power generation unit 3 provides power for the cleaning unit 2, enabling the power generation unit 3 to drive the cleaning unit 2 to reciprocate in the water diversion canal 1, thereby achieving the effect of cleaning the garbage and silt in the water diversion canal 1 and avoiding the phenomenon that the water diversion canal 1 is blocked due to garbage and deposited silt.

[0077] In the present invention, a housing 31 is fixedly connected inside the water diversion canal 1. A first rotating shaft 32 is rotatably connected inside the housing 31. Propeller blades 33 are provided on the first rotating shaft 32. A filter plate 34 is fixedly connected to the housing 31. A generator set 35 is arranged outside the water diversion canal 1 and is connected to the first rotating shaft 32. An energy storage tank 36 is arranged on one side of the generator set 35 and is connected to the generator set 35. A fixing frame 21 is fixedly connected to the water diversion canal 1. A reciprocating lead screw 22 is rotatably connected to the fixing frame 21. A scraping plate 23 is provided on the reciprocating lead screw 22. A first wire mesh 231 is fixedly connected to the side of the scraping plate 23 away from the bottom of the water diversion canal 1;

[0078] When the field needs to be irrigated, the water of the river flows into the water diversion canal 1 and flows into the housing 31 through the filter plate 34. Since the first rotating shaft 32 is rotatably connected inside the housing 31 and the propeller blades 33 are provided on the first rotating shaft 32, when the water flows through the housing 31, the water flow pushes the propeller blades 33 to drive the first rotating shaft 32 to rotate. The first rotating shaft 32 is connected to the generator set 35, and the first rotating shaft 32 causes the generator set 35 to generate electricity and store the electric energy in the energy storage tank 36. On the one hand, the fields are often far from the residential areas, so most farmers need to ride electric bicycles to the fields. If the electric bicycles run out of power, the farmers can charge the electric bicycles through the energy storage tank 36 to prevent the farmers from being unable to ride home due to the lack of power of the electric bicycles. On the other hand, during the autumn harvest, in order to rush to harvest the crops, the farmers often need to harvest the crops at night. The farmers can connect their self - carried lighting facilities to the energy storage tank 36 to provide certain lighting for working in the fields at night. While the first rotating shaft 32 is connected to the generator set 35 to generate electricity, the first rotating shaft 32 is also connected to the reciprocating lead screw 22. Therefore, the rotation of the first rotating shaft 32 drives the reciprocating lead screw 22 to rotate together. Since the scraping plate 23 is provided on the reciprocating lead screw 22, the rotation of the reciprocating lead screw 22 drives the scraping plate 23 to reciprocate in the water diversion canal 1. The first wire mesh 231 is fixedly connected above the scraping plate 23, so that while the first wire mesh 231 clears the floating garbage in the water diversion canal 1, the water flow can flow through the scraping plate 23 smoothly. The lower part of the scraping plate 23 scrapes the silt deposited at the bottom of the water diversion canal 1, thereby preventing the water diversion canal 1 from being blocked due to excessive garbage and deposited silt in the water diversion canal 1.

[0079] In the present invention, a drain pipe 4 is fixedly connected to the diversion canal 1. A second rotating shaft 41 is rotatably connected inside the drain pipe 4, and a spiral blade 42 is fixedly connected to the second rotating shaft 41. A mud guard 5 is fixedly connected inside the diversion canal 1. One end of the mud guard 5 is rotatably connected to the reciprocating lead screw 22. A collection box 6 is provided above the mud guard 5, and the collection box 6 is slidably connected to the mud guard 5 through a buckle. A second wire mesh 61 is fixedly connected to the collection box 6. When the reciprocating lead screw 22 rotates to drive the scraper 23 to reciprocate inside the diversion canal 1, the scraper 23 will push the floating garbage inside the diversion canal 1 into the collection box 6. At the same time, the second wire mesh 61 on the collection box 6 also facilitates the water flow through the collection box 6. The second wire mesh 61 intercepts the garbage, thereby collecting the floating garbage. After the collection box 6 collects the garbage, it is slid off from the mud guard 5, and then the garbage inside the collection box 6 is processed; the silt at the bottom of the diversion canal 1 is scraped off below the scraper 23. The scraper 23 continues to move forward, and the water flows through the first wire mesh 231 above the scraper 23. The silt deposited below the scraper 23 is pushed into the drain pipe 4. The water flow pushes the second rotating shaft 41 inside the drain pipe 4 to drive the spiral blade 42 to rotate together, so as to quickly discharge the silt into the field through the spiral blade 42. Since most of the silt in the diversion canal 1 flows in from the river and has certain nutrients, directly discharging the silt into the field can improve the soil quality of the field. Since the mud guard 5 is located on one side of the drain pipe 4, the mud guard 5 can block the silt scraped by the scraper 23, so that the silt moves into the drain pipe 4, thereby discharging the vast majority of the silt.

[0080] In the present invention, a mounting frame 7 is hinged to the scraper 23, and a mud agitator 8 is rotatably connected to the mounting frame 7. Before the scraper 23 scrapes the silt at the bottom of the diversion canal 1, the movement of the scraper 23 drives the water flow to drive the mud agitator 8 to rotate. The mud agitator 8 agitates the deposited silt, reduces the resistance of the silt to the scraper 23, and facilitates the scraper 23 to scrape the silt.

[0081] Most of the garbage and sediment in the water diversion channel 1 takes some time to generate. Continuously cleaning the water diversion channel 1 with the scraper 23 will affect the power generation of the power generation unit 3. Therefore, in the present invention, a docking shell 9 is rotatably connected to one end of the first rotating shaft 32 close to the reciprocating lead screw 22. A plug 10 is arranged in the docking shell 9. A circular groove 321 is formed on the first rotating shaft 32. The first rotating shaft 32 is rotatably connected to the reciprocating lead screw 22. One end of the reciprocating lead screw 22 is located in the circular groove 321. Through holes 221 through which the plug 10 can pass are formed on both the first rotating shaft 32 and the reciprocating lead screw 22. When it is necessary to clean the garbage and silt in the water diversion channel 1, the plug 10 is made to pass through the through hole 221, so that the first rotating shaft 32 and the reciprocating lead screw 22 are connected to each other. The first rotating shaft 32 drives the reciprocating lead screw 22 to rotate. After the cleaning is completed, the plug 10 is removed from the through hole 221 to disconnect the first rotating shaft 32 from the reciprocating lead screw 22, thereby achieving the effect of periodically cleaning the water diversion channel 1. Using the plug 10 to connect and disconnect the first rotating shaft 32 and the reciprocating lead screw 22 is economical and simple to operate.

[0082] In the present invention, a groove 91 is formed in the docking shell 9. A clamping ball 12 of a first spring 11 is arranged in the groove 91. A clamping groove 101 matching with the clamping ball 12 is formed on the plug 10. When the plug 10 is inserted into the docking shell 9 to connect the first rotating shaft 32 and the reciprocating lead screw 22, the plug 10 presses the clamping ball 12 in the groove 91 to move into the groove 91. When the plug 10 moves to a certain position, the clamping ball 12 is pressed into the clamping groove 101 due to the elastic force of the first spring 11 to prevent the first rotating shaft 32 from driving the docking shell 9 to rotate and causing the plug 10 to fall off. Fixing the plug 10 through the clamping ball 12 and the clamping groove 101 does not prevent the plug 10 from being pulled out. Since two-thirds of the clamping ball 12 is located in the groove 91, when the plug 10 is pulled out, the clamping ball 12 will not fall out.

[0083] In the present invention, a cross-shaped sliding groove 322 is formed on a first rotating shaft 32. A second spring 13 and a cross-shaped slider 14 are arranged in the cross-shaped sliding groove 322. One end of the second spring 13 is fixedly connected to the inner wall of the cross-shaped sliding groove 322, and the other end of the second spring 13 is fixedly connected to the cross-shaped slider 14. The cross-shaped slider 14 is fixedly connected to a propeller blade 33. When water flows into a housing 31, a filter plate 34 filters the garbage in the water flow. However, it is inevitable that some garbage still enters the housing 31. If the garbage jams the propeller blade 33, at this time, the propeller blade 33 will be subjected to a greater impact force of the water flow due to being jammed by the garbage. When the impact force of the water flow is greater than the elastic force of the second spring 13, the water flow will push a single propeller blade 33 to drive the cross-shaped slider 14 to slide in the cross-shaped sliding groove 322, so that the blocked propeller blade 33 moves radially relative to another propeller blade 33, facilitating the garbage to flow out from the gap between the propeller blades 33, thereby enabling the water flow to wash out the jammed garbage from the housing 31, enabling the propeller blade 33 to rotate again. At the same time, the cross-shaped slider 14 prevents the propeller blade 33 from moving laterally relative to the first rotating shaft 32.
