Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering drainage, and in particular to an automatic drainage system for water conservancy engineering construction. Background Art

[0002] In the construction of agricultural water conservancy projects, it is necessary to open corresponding drainage and irrigation channels according to irrigation requirements. At the same time, in order to meet the connectivity between multiple drainage and irrigation channels and the diversion of water bodies, corresponding water storage pits are often set up between multiple drainage and irrigation channels, and the drainage system is used to send the water in the water storage pits to adjacent drainage and irrigation channels to achieve overall irrigation needs.

[0003] The current drainage system is generally a drainage pipe installed at the bottom of the water storage pit or a water pump installed around the water storage pit. There is a problem of blockage when draining water through the drainage pipe, and when the water flow is large or there is heavy rain, the drainage speed is difficult to keep up with the rising speed of the accumulated water. At this time, the water in the water storage pit is easy to overflow and flood the surrounding roads and farmland. Although the drainage speed is faster when using a water pump to pump water, manual control of the water pump switch is required, and there is a problem of untimely drainage. If the water content is small, using a water pump will also result in serious energy waste.

DETAILED DESCRIPTION

[0037] Reference Figure 1-Figure 13 An automatic drainage system for water conservancy project construction includes a water retaining support plate 1, a water pump and a drainage pipe 2. The water pump can specifically adopt an IS125-100-315C model water pump. The drainage pipe 2 is a pipe for automatic drainage arranged at the bottom of a water storage pit. According to the specific situation, a corresponding straight pipe or curved pipe is selected to transport the accumulated water in the water storage pit to an adjacent drainage irrigation channel or elsewhere. When using the device, the water retaining support plate 1 is fixed in the water storage pit, and one end of its opening is directed toward the drainage irrigation channel directly connected to the water storage pit. Irrigation canal is used to collect water in the drainage irrigation canal. The water retaining support plate 1 can be of the same size as the opened water storage pit. At this time, the water retaining support plate 1 can also be used to support the water storage pit to improve its stability. After the installation of the water retaining support plate 1 is completed, the water pump is placed on the ground outside the water storage pit, and the water pump suction port is connected to the bottom of the water storage pit through a water pipe. The discharge port of the water pump inputs the pumped water to other places through another water pipe, so as to keep the water in the water storage pit at a stable liquid level.

[0038] The utility model also includes a drainage connection part, which is used to connect the water retaining support plate 1 with the drainage pipe 2 and discharge the water in the water retaining support plate 1. The drainage connection part includes a connecting pipe 3 which is threadedly and sealingly connected to the water retaining support plate 1, and a threaded inner pipe 4 which is threadedly matched with the drainage pipe 2 is fixedly installed at the bottom of the connecting pipe 3. When the water retaining support plate 1 is fixed in the water storage pit, the threaded inner pipe 4 is first aligned with the drainage pipe 2, and then the connecting pipe 3 is rotated to make it close to the drainage pipe 2 on the water retaining support plate 1. The connection between the connecting pipe 3 and the drainage pipe 2 is realized by utilizing the design of the threaded inner pipe 4. The top of the connecting pipe 3 is sealed and rotatably connected to the water inlet pipe 7, and a plurality of water inlet holes 8 are provided on the side wall of the water inlet pipe 7. An annular connecting groove 5 is provided on the side wall of the end of the connecting pipe 3 away from the threaded inner pipe 4, and an annular sealing member 6 fixedly connected to the water inlet pipe 7 is installed in the annular connecting groove 5 for sealing and rotation. Through the cooperation between the annular connecting groove 5 and the annular sealing member 6, the water inlet pipe 7 can be rotated relative to the connecting pipe 3, and the sealing of the connection between the two can be ensured. After the connection between the connecting pipe 3 and the drain pipe 2 is completed, the accumulated water in the water storage pit can enter the water inlet pipe 7 through multiple water inlet holes 8 and be discharged from the drain pipe 2. By controlling the installation height of the bottom of the water inlet hole 8, the highest water level in the water storage pit can be set. When the water level in the water storage pit is higher than the bottom height of the water inlet hole 8, the water inlet hole 8 can be automatically drained.

[0039] The drainage opening and closing part is used to control the switch of multiple water inlet holes 8. The drainage opening and closing part includes an outer sleeve 11 rotatably connected to the water retaining support plate 1. An annular groove 9 is provided on the water retaining support plate 1, and a rotating ring 10 fixedly connected to the outer sleeve 11 is sealed and rotatably installed in the annular groove 9. The inner diameter of the outer sleeve 11 is the same as the outer diameter of the water inlet pipe 7. The advantage of the size design here is that the sealing between the outer sleeve 11 and the water inlet pipe 7 can be ensured when the two are fitted. A plurality of alignment holes 12 corresponding to the corresponding water inlet holes 8 are provided on the side wall of the outer sleeve 11. When the alignment holes 12 are relative to the water inlet holes 8, the water inlet pipe 7 is in an open state, and the accumulated water can be discharged therethrough. When the alignment holes 12 and the water inlet holes 8 are completely staggered, the outer sleeve 11 shields the water inlet pipe 7, and the accumulated water cannot enter the water inlet pipe 7 at this time.

[0040] Two guide blocks 13 are fixedly installed on the inner wall of the outer sleeve 11, and two guide grooves 14 matching the corresponding guide blocks 13 are provided on the side wall of the water inlet pipe 7, and arc grooves 15 are provided on the side wall of the two guide grooves 14 away from the end of the drain pipe 2, and the depth of the guide grooves 14 is equal to the length of the threaded inner pipe 4. Through this design, after the threaded inner pipe 4 is completely connected to the drain pipe 2, the guide block 13 can be moved to the end of the guide groove 14 away from the drain pipe 2 and opposite to the arc groove 15. In the process of the guide block 13 moving along the guide groove 14, since the outer sleeve 11 remains stationary, the water inlet pipe 7 can remain Stationary, that is, the rotation of the connecting pipe 3 will not drive the water inlet pipe 7 to rotate at the same time, thereby ensuring that the positions of the water inlet hole 8 and the alignment hole 12 will not change. The water inlet pipe 7 is kept in an open state during and after the installation process. The angle of the arc groove 15 is greater than or equal to the angle of the water inlet hole 8. When the guide block 13 enters the arc groove 15, the rotation of the outer sleeve 11 will first drive the guide block 13 to rotate in the arc groove 15. Therefore, the outer sleeve 11 rotates relative to the water inlet pipe 7, thereby causing the alignment hole 12 to deflect relative to the water inlet hole 8, allowing the outer sleeve 11 to shield the water inlet pipe 7, so that the water inlet pipe 7 is in a closed state.

[0041] The silt cleaning and crushing part is used to remove the silt and impurities in the water inlet pipe 7. The silt cleaning and crushing part includes a mounting rod 16 fixedly installed in the connecting pipe 3, and a screw rod 17 is rotatably installed on the mounting rod 16. A movable plate 18 is threadedly installed at one end of the water inlet pipe 7. A fixed rod 19 is fixedly installed on the mounting rod 16. A through hole 20 that slidably cooperates with the fixed rod 19 is opened on the movable plate 18. When the screw rod 17 rotates, the movement direction of the movable plate 18 is limited due to the cooperation between the through hole 20 and the fixed rod 19. At this time, the movable plate 18 moves along the screw rod 17 from the end of the water inlet pipe 7 away from the connecting pipe 3 to the end close to the connecting pipe 3. In this process, the silt and impurities in the water inlet pipe 7 can be transported to the connecting pipe 3, so as to avoid the problem that the silt and impurities continue to accumulate in the water inlet pipe 7, causing it to be blocked and affecting the drainage speed.

[0042] A positioning plate 21 is fixedly installed at the end of the screw rod 17 away from the movable plate 18, and a torsion spring 22 is installed between the positioning plate 21 and the mounting rod 16. With the cooperation of the positioning plate 21 and the torsion spring 22, the screw rod 17 can be kept stationary on the mounting rod 16 when not driven by external force, so that the movable plate 18 can be kept in the water inlet pipe 7 at a position away from the end of the drainage pipe 2, thereby avoiding the problem that the sludge and impurities accumulated at the end of the movable plate 18 away from the drainage pipe 2 are difficult to be discharged later due to the movement of the movable plate 18 during the process of discharging accumulated water in the water inlet pipe 7.

[0043] A rotating groove is provided on the side wall of the end of the mounting rod 16 away from the movable plate 18, and a connecting ring 23 is sealingly and rotatably connected in the rotating groove, and a sealing sleeve 24 is fixedly mounted on the connecting ring 23 and is sealingly and rotatably connected to the positioning plate 21. Through the design of the sealing sleeve 24, the torsion spring 22 and the positioning plate 21 can be shielded, thereby avoiding the problem of sludge and impurities being stuck on the torsion spring 22 during the process of discharging sludge and impurities, resulting in great difficulty in the subsequent resetting of the torsion spring 22.

[0044] A rotating disk 27 is rotatably mounted on the movable plate 18, and a plurality of cutting blades 28 are fixedly mounted on one end of the rotating disk 27 away from the movable plate 18. A driving assembly matched with the rotating disk 27 is mounted on the movable plate 18, and a mounting ring 26 is fixedly mounted on the side wall of the rotating disk 27. A mounting groove 25 rotatably matched with the mounting ring 26 is provided on the side wall of the movable plate 18. The diameter of the mounting groove 25 and the inner diameter of the rotating disk 27 are both larger than the diameter of the screw rod 17. When the movable plate 18 moves in the water inlet pipe 7 to push the sludge and impurities, the rotating disk 27 is rotated to drive the plurality of cutting blades 28 to rotate, so that large pieces of sludge and large-sized impurities (such as weeds, plastic bags, etc.) can be cut into smaller pieces, so that they can be discharged smoothly from the drain pipe 2 later.

[0045] The driving assembly is composed of a fixed gear ring 29, a T-ring 30, a driving gear ring 31, a connecting gear 32, a protrusion 33 and a spiral groove 34. The fixed gear ring 29 is fixedly mounted on the side wall of the mounting ring 26. The T-ring 30 is rotatably connected in the movable plate 18, and the T-ring 30 is coaxial with the through hole 20. The driving gear ring 31 is fixedly mounted on the T-ring 30. The connecting gear 32 is rotatably mounted between the fixed gear ring 29 and the driving gear ring 31, and the two ends of the connecting gear 32 are respectively meshed with the fixed gear ring 29 and the driving gear ring 31. The protrusion 33 is fixedly mounted on the driving gear ring 31. On the inner wall of the gear ring 31, a spiral groove 34 is provided on the fixed rod 19, and the spiral groove 34 cooperates with the protrusion 33. When the movable plate 18 moves in the water inlet pipe 7, the driving gear ring 31 moves relative to the fixed rod 19 at the same time. At this time, under the cooperation of the protrusion 33 and the spiral groove 34, the driving gear ring 31 rotates, and then drives the rotating disk 27 to rotate through the cooperation of the connecting gear 32 and the fixed gear ring 29, so that the multiple cutting blades 28 rotate during the movement of the movable plate 18, so as to realize the cutting and crushing of sludge and impurities in the process of pushing them.

[0046] The floating control part controls the rotation of the outer sleeve 11 by the water level height in the water retaining support plate 1. The floating control part includes a floating plate 36 slidably installed in the water retaining support plate 1. Two lifting blocks 41 are fixedly installed on the side wall of the floating plate 36. Two lifting grooves 42 corresponding to the lifting blocks 41 are provided on the inner wall of the water retaining support plate 1. The moving direction of the floating plate 36 in the water retaining support plate 1 can be limited by the cooperation between the lifting blocks 41 and the lifting grooves 42. The floating plate 36 is made of buoyant material and has a certain weight. It can maintain its position at the bottom of the water retaining support plate 1 when it is not subject to buoyancy. When the accumulated water is higher than the set water level, the floating plate 36 can move upward along the water retaining support plate 1 under the action of buoyancy.

[0047] A touch switch electrically connected to the water pump is fixedly installed on the water retaining support plate 1, and the touch switch corresponds to the position of the floating plate 36. When the floating plate 36 moves up to a certain distance, it triggers the touch switch. At this time, the touch switch can control the operation of the water pump to automatically extract and discharge excess accumulated water. It has high sensitivity and can effectively avoid the problem of excessive water level in the water storage pit overflowing and flooding surrounding roads and farmland.

[0048] A rotating rod 35 is rotatably installed on the water retaining support plate 1, and a thread groove is provided on the rotating rod 35 to match the thread of the floating plate 36. The bottom height of the thread groove is consistent with the top height of the water inlet pipe 7, and the top height of the thread groove is consistent with the installation height of the touch switch. Therefore, when the floating plate 36 moves up to the maximum distance, the water pump can pump water. In addition, the specific pumping time of the water pump can be controlled according to the different heights of the touch switch installed in the water retaining support plate 1, as long as the installation height of the touch switch is less than or equal to the top height of the thread groove.

[0049] The water retaining support plate 1 is provided with an installation cavity 37 which cooperates with the rotating rod 35, and the installation cavity 37 is communicated with the annular groove 9. A driving gear 38 is installed in the installation cavity 37 through the rotation of the rotating shaft, and a belt transmission structure 39 is installed between the driving gear 38 and the bottom of the rotating rod 35. A connecting gear ring 40 which meshes with the driving gear 38 is fixedly installed on the side wall of the rotating ring 10. When the accumulated water begins to increase, the floating plate 36 moves up under the action of buoyancy. When the floating plate 36 moves up to a certain height, the cooperation between the floating plate 36 and the threaded groove on the rotating rod 35 makes the rotating rod 35 starts to rotate, and then drives the driving gear 38 to rotate under the action of the belt transmission structure 39, so that the outer sleeve 11 rotates by utilizing the meshing effect of the driving gear 38 and the connecting gear ring 40. At the initial stage of the rotation of the outer sleeve 11, the guide block 13 slides in the arc groove 15, so that the outer sleeve 11 rotates relative to the water inlet pipe 7, so that the alignment hole 12 and the water inlet hole 8 are staggered to close the water inlet pipe 7. At this time, the accumulated water will not enter the water inlet pipe 7. The belt transmission structure 39 is a prior art, and its working principle and specific structure are not described here.

[0050] As the outer sleeve 11 continues to rotate, the guide block 13 moves to the maximum distance in the arc groove 15. At this time, the outer sleeve 11 drives the water inlet pipe 7 to rotate at the same time, so the connecting pipe 3 rotates relative to the water inlet pipe 7, and the screw rod 17 also rotates relative to the movable plate 18. At this time, the movable plate 18 moves in the water inlet pipe 7 toward the end close to the drain pipe 2, pushing the sludge and impurities in the water inlet pipe 7. At the same time, during the movement of the movable plate 18, the driving gear ring 31 moves relative to the fixed rod 19 at the same time, and the driving gear ring 31 rotates by the cooperation of the protrusion 33 and the spiral groove 34, so that the rotating disk 27 on the movable plate 18 rotates, and the multiple cutting blades 28 thereon are used to cut and crush the sludge and impurities, and As the movable plate 18 moves, the crushed sludge and impurities are sent into the connecting pipe 3. When the floating plate 36 moves to the maximum stroke, the movable plate 18 also moves to the maximum stroke in the water inlet pipe 7. At this time, the floating plate 36 touches the touch switch, and the water pump runs to extract and discharge excess water. When the accumulated water is extracted, the water level drops and the floating plate 36 moves down. At this time, the water inlet pipe 7 is opened, and part of the accumulated water enters the water inlet pipe 7 to flush the cut and crushed sludge and impurities. At the same time, the movable plate 18 is reset. At this time, the excess water is effectively discharged, which can ensure that the water body in the water storage pit is at a stable height. At the same time, the inside of the water inlet pipe 7 is also effectively unblocked, which can ensure that it maintains a good drainage volume in the future.

It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
