Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy and hydropower equipment, specifically a clog-proof water diversion device for water conservancy and hydropower. Background Technology

[0002] Water conservancy and hydropower refers to the construction and management of projects that utilize water resources for power generation, irrigation, water supply, flood control, and pollution prevention. It aims to promote the sustainable use of water resources and improve the water resource security capacity for economic and social development. It is a broad and important field that covers multiple aspects such as the development, utilization, protection, and management of water resources, as well as the construction and operation of water conservancy projects.

[0003] In the construction of water conservancy and hydropower projects, corresponding water diversion devices are needed to draw water from lakes and other bodies of water. The existing water diversion devices mainly operate by using water pumps to draw water. However, in actual use, they still have shortcomings. Because the water contains aquatic plants, garbage and other debris, as the water pump is running, these debris will be adsorbed on the outer surface of the filter screen, causing the filter screen to become clogged. At this time, the water diversion efficiency of the water pump will decrease or even fail to work properly. Therefore, improvements are needed. Utility Model Content

[0006] As a preferred embodiment of this utility model, a water pump is fixedly installed on the inner wall of the right side of the sealed box, and a suction pipe is fixedly installed on the left end of the water pump. The other end of the suction pipe passes through the water inlet pipe and extends to the top of the inner surface of the water inlet pipe. The outer surface of the suction pipe and the inner surface of the top end of the water inlet pipe are fixedly sleeved together. A water outlet pipe is fixedly installed on the top end of the water pump. The top end of the water outlet pipe passes through the sealed box and extends to the outside of the sealed box. The outer surface of the water outlet pipe and the inner surface of the top end of the sealed box are fixedly sleeved together.

[0007] As a preferred embodiment of this utility model, a connector is fixedly installed on the right side of the middle front end of the sealing box, and the outer surface of the connector is fixedly connected to the outer surface of the water outlet pipe. Lifting lugs are fixedly installed on the front side of the middle of the upper and lower ends of the sealing box, respectively.

[0008] As a preferred embodiment of this utility model, a second motor is fixedly installed on the top of the inner wall on the right side of the counterweight base, and a lead screw is fixedly sleeved on the other end of the output shaft of the second motor.

[0009] As a preferred embodiment of this utility model, a rectangular block is threaded onto the middle of the outer surface of the lead screw, the top of the rectangular block is movably connected to the bottom of the water pipe, and a diagonal rod is hinged to the bottom of the rectangular block.

[0010] As a preferred embodiment of this utility model, a water-blocking plate is hinged to the bottom end of the inclined rod, the outer surface of the water-blocking plate and the inner surface of the counterweight base are movably connected, and a plug rod is fixedly installed at each of the four corners of the bottom end of the water-blocking plate, the bottom end of the plug rod penetrating the counterweight base and extending to the outside of the counterweight base.

[0013] 1. This utility model includes a scraper, a crossbar, a first motor, a rotating rod, and a round rod. When the first motor is started, the rotating shaft will drive the rotating rod to rotate. Since the round rod and the rotating rod are fixedly connected and the round rod and the crossbar are movably connected, the round rod will rotate along with the rotating rod. This causes the round rod to exert a thrust on the crossbar, pushing the crossbar and the scraper to move along the outer surface of the filter screen. In this way, the scraper can clean the filter screen and prevent it from becoming clogged.

[0014] 2. This utility model, by setting up a lead screw, a rectangular block, a diagonal rod, a water-blocking plate, and a plug rod, will cause the lead screw to rotate when the second motor is started. Since the outer surface of the lead screw and the inner surface of the rectangular block are threaded together, the rectangular block will move along with the top of the diagonal rod under the action of the lead screw. This will cause the bottom of the diagonal rod to exert a pulling force on the water-blocking plate, pulling the water-blocking plate and moving the plug rod, thereby retracting the plug rod and improving the convenience of removing the water-drawing device from the water.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6As shown, this utility model provides a clog-resistant water diversion device for water conservancy and hydropower, including a water diversion pipe 1, a sealing box 2 fixedly installed at the top of the water diversion pipe 1, a counterweight base 3 fixedly installed at the bottom of the water diversion pipe 1, a filter screen 4 fixedly sleeved inside the left end of the water diversion pipe 1, a fixing frame 5 fixedly installed at the top of the left end of the counterweight base 3, a scraper 6 movably sleeved on the rear side of the outer surface of the fixing frame 5, the right end of the scraper 6 movably connected to the left end of the water diversion pipe 1, the sealing box 2, the counterweight base 3, and the filter screen 4, a crossbar 7 fixedly installed at the top of the scraper 6, and the left end of the crossbar 7 movably sleeved inside... A limit frame 8 is connected to the bottom end of the limit frame 8 and the top end of the sealing box 2. A first motor 9 is fixedly installed on the left side of the top end inside the sealing box 2. A rotating shaft 10 is fixedly sleeved on the other end of the output shaft of the first motor 9. The top end of the rotating shaft 10 passes through the sealing box 2 and extends to the outside of the sealing box 2 and is fixedly sleeved with a rotating rod 11. The bottom end of the rotating rod 11 is movably connected to the top end of the sealing box 2. The top end of the rotating rod 11 is movably connected to the bottom end of the crossbar 7. A round rod 12 is fixedly sleeved inside the rotating rod 11. The outer surface of the round rod 12 is movably sleeved with the inner surface of the right end of the crossbar 7.

[0024] When the first motor 9 starts, the rotating shaft 10 will drive the rotating rod 11 and the round rod 12 to rotate. Since the round rod 12 is movably sleeved inside the crossbar 7, the outer surface of the round rod 12 will generate a thrust on the inner surface of the crossbar 7. The thrusting crossbar 7 moves along the outer surface of the limiting frame 8. Since the crossbar 7 and the scraper 6 are fixedly connected, the scraper 6 will move along the outer surface of the fixed frame 5 under the drive of the crossbar 7, thereby cleaning the filter screen 4. This will prevent the filter screen 4 from becoming clogged and affecting the normal operation of the water intake device.

[0025] A water pump 13 is fixedly installed on the right inner wall of the sealed box 2. A suction pipe 14 is fixedly installed on the left end of the water pump 13. The other end of the suction pipe 14 passes through the water inlet pipe 1 and extends to the top of the inner surface of the water inlet pipe 1. The outer surface of the suction pipe 14 and the inner surface of the top of the water inlet pipe 1 are fixedly sleeved. A water outlet pipe 15 is fixedly installed on the top of the water pump 13. The top of the water outlet pipe 15 passes through the sealed box 2 and extends to the outside of the sealed box 2. The outer surface of the water outlet pipe 15 and the inner surface of the top of the sealed box 2 are fixedly sleeved.

[0026] When the water pump 13 starts, the water inside the water inlet pipe 1 will be discharged through the water inlet pipe 14 and the water outlet pipe 15, thus completing the water inlet operation.

[0027] A connector 16 is fixedly installed on the right side of the front middle of the sealing box 2. The outer surface of the connector 16 is fixedly connected to the outer surface of the water outlet pipe 15. Lifting lugs 17 are fixedly installed on the front side of the middle of the upper and lower ends of the sealing box 2.

[0028] The presence of connector 16 facilitates the connection of water pipes, while the presence of lug 17 facilitates the connection of lifting ropes.

[0029] The second motor 18 is fixedly installed on the top of the inner wall on the right side of the counterweight base 3, and the other end of the output shaft of the second motor 18 is fixedly connected to the lead screw 19.

[0030] When the second motor 18 starts, it will cause the lead screw 19 to rotate.

[0031] Among them, a rectangular block 20 is threaded in the middle of the outer surface of the lead screw 19, the top of the rectangular block 20 is movably connected to the bottom of the water pipe 1, and a diagonal rod 21 is hinged to the bottom of the rectangular block 20.

[0032] When the lead screw 19 rotates, the rectangular block 20, which is threadedly connected to the lead screw 19, will move along with the top of the diagonal rod 21.

[0033] Among them, the bottom end of the diagonal rod 21 is hinged to a water-blocking plate 22, the outer surface of the water-blocking plate 22 and the inner surface of the counterweight base 3 are movably connected, and the four corners of the bottom end of the water-blocking plate 22 are respectively fixedly installed with insert rods 23, the bottom end of the insert rods 23 penetrates the counterweight base 3 and extends to the outside of the counterweight base 3.

[0034] When the top of the diagonal rod 21 moves, the bottom of the diagonal rod 21 will exert a pulling force on the water-blocking plate 22, which will pull the water-blocking plate 22 and move the insertion rod 23.

[0035] Among them, the bottom of the inner walls on the left and right sides of the counterweight base 3 is respectively provided with limiting grooves 24, and the bottom of the limiting groove 24 is movably sleeved with a limiting block 25. The outer surface of the limiting block 25 is fixedly connected to the outer surface of the water-proof plate 22.

[0036] The inner surface of the limiting groove 24 and the outer surface of the limiting block 25 are both smooth, thus ensuring that the limiting block 25 will not get stuck when it moves along the inside of the limiting groove 24.

[0037] Working principle and usage process of this utility model:

[0038] First, the operator connects the water pipe and connector 16, then connects the hoisting rope and hoisting lug 17. The water intake device is then placed in the water and secured with the insertion rod 23. At this point, the water pump 13 is started, allowing water to be discharged from the water intake pipe 1, suction pipe 14, outlet pipe 15, and connector 16 after being filtered through the filter screen 4, thus completing the water intake operation. During the operation of the water pump 13, the operator starts the first motor 9, causing the rotating shaft 10 to drive the rotating rod 11 and the round rod 12 to rotate. This causes the outer surface of the round rod 12 to generate a thrust on the inner surface of the crossbar 7, pushing the crossbar 7 and the scraper 6 to move along the outer surface of the filter screen 4, thereby cleaning the filter screen 4 and preventing water plants, debris, and other impurities from adhering to the outer surface of the filter screen 4 and causing blockage.

[0039] After the water diversion is completed, the operator stops the water pump 13 and the first motor 9 and starts the second motor 18, causing the lead screw 19 to rotate. At this time, the rectangular block 20 threaded onto the outer surface of the lead screw 19 will move along the bottom of the water pipe 1, causing one end of the inclined rod 21 to move. This will cause the other end of the inclined rod 21 to exert a pulling force on the water baffle plate 22, pulling the water baffle plate 22 and the insertion rod 23 to move upward along the inner surface of the counterweight base 3, thereby retracting the insertion rod 23 and preventing it from remaining stuck at the bottom of the water when the water diversion device is retrieved, which would cause trouble for the retrieval.
