[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1 Please see Figure 1-5 The present invention provides the following technical solution: a water supply device for dam fill material of a hydropower station, including a top box 1, a plurality of support columns 5 fixedly installed below the top box 1, a second nozzle 3 fixedly installed below the top box 1 and between the plurality of support columns 5, a water spraying and filtering mechanism 2 is provided near the center of the top box 1, and an auxiliary recycling mechanism 4 is provided below the second nozzle 3. The water spray filtration mechanism 2 includes a first pump body 21, which is fixedly installed on the top of the top box 1. Electric telescopic rods 26 are provided on both sides of the first pump body 21. Water supply pipes 23 are provided at both ends of the top box 1. A first nozzle 25 is fixedly installed below the water supply pipes 23. The electric telescopic rods 26 and the water supply pipes 23 are connected by a moving plate 27. A water inlet pipe 28 is provided diagonally above the first pump body 21. A filter assembly 29 is provided on one side of the water inlet pipe 28.
[0021] Specifically, sealing rings 24 are fixedly installed at both ends of the top box 1 and on the outside of the water supply pipe 23. By adopting the above technical solution, water leakage can be prevented through the sealing rings 24, thereby ensuring the normal operation of the work.
[0022] Specifically, a limiting ring 22 is fixedly installed on the outer side of the end of the water supply pipe 23 away from the first nozzle 25. By adopting the above technical solution, the movement of the water supply pipe 23 can be limited by the limiting ring 22 to prevent it from deviating from the preset track and to ensure the safety and stability of the water addition range adjustment process.
[0023] Specifically, the filter assembly 29 includes a connecting box 294. The liquid outlet of the first pump body 21 is connected to the water inlet pipe 28 through the connecting box 294. A filter screen 293 is fixedly installed on the inner side of the connecting box 294. By adopting the above technical solution, impurities in the water can be intercepted through the cooperation of the filter screen 293 and other structures, thereby reducing the possibility of blockage and damage inside the device.
[0024] Specifically, a threaded block 291 is installed on the top of the connecting box 294 by means of threads. By adopting the above technical solution, the threaded block 291 can be unscrewed when needed to remove impurities and other objects blocked by the filter screen 293, thus better meeting the needs of the work.
[0025] Specifically, a motor 295 is fixedly installed on the side of the connecting box 294 away from the water inlet pipe 28, and a cleaning brush 292 is fixedly installed on the side of the output end of the motor 295 and on the side of the filter screen 293 close to the water inlet pipe 28. By adopting the above technical solution, impurities on the filter screen 293 can be removed by the cooperation of the motor 295 and the cleaning brush 292, preventing the filter screen 293 from being blocked and maintaining stable water supply efficiency.
[0026] In this embodiment, when it is necessary to add water to the fill material of the hydropower station dam using the device, the loading vehicle carrying the fill material needs to be driven to the bottom of the top box 1, and the water inlet pipe 28 in the water spraying and filtering mechanism 2 is connected to the external water source through the pipeline. Then, the two electric telescopic rods 26 are activated, thereby driving the two moving plates 27 connected to them to move. The moving plates 27 then pull the water supply pipe 23 and the first nozzle 25 fixed below it to move, thereby adjusting the spray range. The first pump body 21 is activated. Under the action of the first pump body 21, the external water enters the connecting box 294 in the filter assembly 29 through the water inlet pipe 28. The filter screen 293 fixed inside the connecting box 294 will intercept impurities in the water. At the same time, the motor 295 is activated, and its output end drives the cleaning brush 292 to rotate, removing the impurities attached to the filter screen 293 and preventing the filter screen 293 from clogging.
[0027] Water then passes through the first pump body 21 into the top box 1, and then passes through the second nozzle 3 and the first nozzle 25 under the two water supply pipes 23 respectively, spraying onto the filling material inside the vehicle to add water. When needed, the staff can unscrew the threaded block 291 on the top of the connecting box 294 to remove the impurities intercepted by the filter screen 293. The limiting ring 22 prevents the water supply pipe 23 from detaching from the top box 1, the sealing ring 24 prevents leakage, and the support column 5 provides support.
[0028] Example 2 The difference between this embodiment and embodiment 1 is that the auxiliary recycling mechanism 4 includes a support platform 41. The support platform 41 is fixedly installed directly below multiple pillars 5. A water storage tank 46 is provided on the inner side of the support platform 41. A load-bearing steel mesh 42 is fixedly installed on the inner side of the top of the water storage tank 46. By adopting the above technical solution, the water that is accidentally spilled can be recycled through the cooperation of the load-bearing steel mesh 42 and the water storage tank 46, thereby reducing the waste of water resources and better meeting the needs of the work.
[0029] Specifically, ramps 43 are fixedly installed on both sides of the support platform 41. By adopting the above technical solution, it is convenient for the loading vehicle to climb onto the support platform 41, which better meets the needs of the work.
[0030] Specifically, a second pump body 47 is fixedly installed on the inner side of the support platform 41 and below the water storage tank 46. A hose 45 is fixedly installed on one side of the liquid outlet end of the second pump body 47. By adopting the above technical solution, it is convenient for staff to take water from the water storage tank 46, which better meets the needs of the work.
[0031] Specifically, a mesh 44 is fixedly installed on the side of the hose 45 away from the second pump body 47. By adopting the above technical solution, the mesh 44 can prevent external impurities from entering the hose 45, thereby preventing the hose 45 from becoming clogged.
[0032] In this embodiment, when adding water, the loader needs to climb onto the support platform 41 in the auxiliary recycling mechanism 4. The ramp 43 reduces the difficulty of climbing onto the support platform 41. Then, some of the water that is accidentally spilled during the water adding process will pass through the load-bearing steel mesh 42 and enter the water storage tank 46 for recycling, thereby reducing water waste. When the recycled water needs to be used, the staff will align the end of the hose 45 with the required position and start the second pump body 47. Then the water will pass through the second pump body 47 and the hose 45 and be discharged, thereby using the recycled water. The mesh 44 plays the role of isolating impurities.
[0033] The working principle and usage process of this invention are as follows: When it is necessary to use the device to add water to the fill material of the hydropower station dam, the loading vehicle carrying the fill material needs to be driven to the bottom of the top box 1, and the water inlet pipe 28 in the water spraying and filtering mechanism 2 is connected to the external water source through the pipeline. Then, the two electric telescopic rods 26 are activated, thereby driving the two moving plates 27 connected to them to move. The moving plates 27 then pull the water supply pipe 23 and the first nozzle 25 fixed below it to move, thereby adjusting the spray range. The first pump body 21 is activated. Under the action of the first pump body 21, the external water enters the connecting box 294 in the filter assembly 29 through the water inlet pipe 28. The filter screen 293 fixed inside the connecting box 294 will intercept impurities in the water. At the same time, the motor 295 is activated, and its output end drives the cleaning brush 292 to rotate, removing the impurities attached to the filter screen 293 and preventing the filter screen 293 from clogging.
[0034] Water then passes through the first pump body 21 into the top box 1, and then passes through the second nozzle 3 and the first nozzle 25 under the two water supply pipes 23 respectively, spraying onto the filling material inside the vehicle to add water. When needed, the staff can unscrew the threaded block 291 on the top of the connecting box 294 to remove the impurities intercepted by the filter screen 293. The limiting ring 22 prevents the water supply pipe 23 from detaching from the top box 1, the sealing ring 24 prevents leakage, and the support column 5 provides support.
[0035] When adding water, the loader needs to climb onto the support platform 41 in the auxiliary recycling mechanism 4. The ramp 43 reduces the difficulty of climbing onto the support platform 41. Then, some of the water that is accidentally spilled during the water adding process will pass through the load-bearing steel mesh 42 and enter the water storage tank 46 for recycling, thereby reducing water waste. When the recycled water needs to be used, the staff will align the end of the hose 45 with the required position and start the second pump body 47. Then the water will pass through the second pump body 47 and the hose 45 and be discharged, thereby using the recycled water. The screen 44 plays the role of isolating impurities.
