[0001] The utility model relates to the technical field of water conservancy construction, in particular to a water conservancy construction drainage device. Background Art

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. They mainly include flood control, waterlogging removal, irrigation, power generation, water supply, reclamation, soil and water conservation, immigration and water resource protection. Once the foundation pit contains a large amount of water, drainage equipment is needed to drain the water to avoid the accumulation of puddles that affect the normal construction of water conservancy.

[0003] A water conservancy construction drainage equipment is disclosed in a Chinese utility model patent with publication number CN218712566U, which specifically relates to the technical field of water conservancy construction drainage, including a movable support plate, a pump is installed above the movable support plate, and the input end of the pump is fixedly connected to a floating drainage component; the floating drainage component includes a suction hose fixedly connected to the input end of the pump, and one end of the suction hose is fixedly connected to a connecting pipe.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: although the connecting pipe in the above-mentioned device floats in the water, some floating objects on the water surface in the foundation pit can still easily cause the connecting pipe to be blocked, and after the water level drops, the sediment content at the bottom of the foundation pit is relatively high, and the sediment can easily block the connecting pipe and even damage the pump. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a water conservancy construction drainage equipment.

[0006] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a water conservancy construction drainage equipment, comprising a base plate, a moving wheel fixed to the bottom of the base plate, a pushing frame fixed to the side wall of the base plate, and a pump fixed to the upper surface of the base plate, the upper surface of the base plate is fixed with a mounting plate, the mounting plate is installed with an adjusting component, the adjusting component comprises a rotating shaft which is arranged through and rotatably connected to the side wall of the mounting plate, a hand wheel fixed to the end of the rotating shaft, and a winding roller fixedly sleeved on the rotating shaft, a drainage pipe is fixed to the side of the pump away from the drainage pipe, a water suction hose is fixed to the winding roller, and a mounting block is fixedly sleeved on one end of the water suction hose away from the pump, a mounting groove is opened at the bottom of the mounting block, a filter screen is arranged on the inner wall of the mounting groove, a cleaning brush is arranged in the mounting groove, the bristles of the cleaning brush are pressed against the lower surface of the filter screen, and a driving component for driving the cleaning brush to move is installed on the mounting block.

[0007] By adopting the above technical solution, when the foundation pit needs to be drained, the staff moves the bottom plate to a suitable position by pushing the frame, and then adjusts the length of the water suction hose by the hand wheel to make the water suction hose enter the water in the foundation pit, and discharges the water in the foundation pit through the pump. When the water flows into the water suction hose, it is filtered through the filter, which reduces the probability of mud and sand clogging the water suction hose and even damaging the pump. When pumping for a long time, mud and sand are easy to clog the filter. At this time, the staff drives the cleaning brush to move through the driving assembly, thereby brushing the filter, reducing the probability of mud and sand clogging the mesh of the filter.

[0008] Furthermore, a slide groove is provided on the inner wall of the mounting groove, and the driving assembly includes a slider fixed to the side wall of the cleaning brush and slidably connected to the slide groove, and a waterproof motor fixed to the side wall of the mounting block, and the output shaft of the waterproof motor passes through the side wall of the mounting block and is rotatably connected. The driving assembly also includes a threaded rod that is penetrated by the slider and threadedly connected, one end of the threaded rod is fixed to the end of the output shaft of the waterproof motor, and the other end of the threaded rod is rotatably connected to the inner wall of the slide groove.

[0009] By adopting the above technical solution, when the filter needs to be cleaned, the staff only needs to drive the threaded rod to rotate through the waterproof motor. Since the threaded rod is threadedly connected to the slider, and the slider is slidably connected to the slide groove, the slider moves axially along the threaded rod, thereby driving the cleaning brush to clean the surface of the filter, reducing the probability of filter clogging.

[0010] Furthermore, the area of ​​a mesh hole on the filter screen is 1-2 square millimeters.

[0011] By adopting the above technical solution, the mesh is set to an area of ​​1-2 square millimeters, which is conducive to the filter net intercepting small particles of mud and sand and other impurities, reducing the probability of mud, sand, gravel and other particles entering the drainage hose and causing blockage, which is conducive to the smooth progress of drainage work.

[0012] Furthermore, a waterproof protective shell for covering the waterproof motor is fixed to the side wall of the mounting block.

[0013] By adopting the above technical solution, the waterproof protective shell provides waterproof protection for the waterproof motor, reducing the probability of the waterproof motor being damaged by water or external force.

[0014] Furthermore, a counterweight block is provided on the fixing sleeve of the side wall of the mounting block.

[0015] By adopting the above technical solution, the counterweight block increases the weight of the mounting block, which is conducive to the water suction hose with adjusted length to sink quickly to a predetermined depth.

[0016] Furthermore, a positioning assembly is installed on the rotating shaft, and the positioning assembly includes a positioning nut sleeved on the rotating shaft and threadedly connected to the rotating shaft.

[0017] By adopting the above technical solution, after the staff adjusts the length of the water suction hose, the staff needs to tighten the positioning nut so that the side wall of the positioning nut is pressed against the side wall of the mounting plate, thereby limiting the rotation of the shaft and reducing the probability of the water suction hose moving due to automatic rotation of the shaft.

[0018] Furthermore, the rotating shaft is sleeved with an annular gasket located between the positioning nut and the mounting plate.

[0019] By adopting the above technical solution, the annular gasket is made of rubber material, and its surface has a large friction coefficient. The side wall of the positioning nut cooperates with the side wall of the mounting plate and presses against the annular gasket, thereby increasing the friction between the side wall of the positioning nut and the side wall of the mounting plate and reducing the probability of the positioning nut rotating. In addition, the annular gasket also reduces the wear between the side wall of the positioning nut and the side wall of the mounting plate.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when it is necessary to drain the foundation pit, the staff moves the bottom plate to a suitable position by pushing the frame, and then adjusts the length of the water pump hose by the hand wheel, so that the water pump hose enters the water in the foundation pit, and the water in the foundation pit is discharged by the pump. When the water flows into the water pump hose, it is filtered by the filter, which reduces the probability of mud and sand blocking the water pump hose and even damaging the pump. When pumping for a long time, mud and sand are easy to block the filter. At this time, the staff drives the cleaning brush to move through the driving component, so as to brush the filter, which reduces the probability of mud and sand blocking the mesh of the filter.

[0022] 2. In this application, when the filter needs to be cleaned, the staff only needs to drive the threaded rod to rotate through the waterproof motor. Since the threaded rod is threadedly connected to the slider, and the slider is slidably connected to the slide groove, the slider moves along the axial direction of the threaded rod, thereby driving the cleaning brush to clean the surface of the filter, reducing the probability of clogging of the filter;

[0023] 3. In this application, the mesh holes are set to an area of ​​1-2 square millimeters, which is conducive to the filter to intercept small particles of mud and sand and other impurities, reducing the probability of mud, sand, gravel and other particles entering the drainage hose and causing blockage, which is conducive to the smooth progress of drainage work.

The mounting plate 5 is a rectangular plate-like structure, and the mounting plate 5 is fixed on the upper surface of the bottom plate 1.

[0032] The adjustment assembly 6 is mounted on the mounting plate 5, and includes a rotating shaft 61, a hand wheel 62, and a winding roller 63. The rotating shaft 61 is a horizontally arranged round rod-shaped structure, and the rotating shaft 61 is arranged through the side wall of the mounting plate 5 and is rotatably connected. The hand wheel 62 is fixed to the end of the rotating shaft 61, and the axis of the hand wheel 62 coincides with the axis of the rotating shaft 61. The winding roller 63 is a round roller-shaped structure, and the winding roller 63 is fixedly sleeved on the rotating shaft 61, and the axis of the winding roller 63 coincides with the axis of the rotating shaft 61.

[0033] The drain pipe 7 is a horizontally arranged circular tubular structure, and the drain pipe 7 is fixed to the side of the pump 4 away from the winding roller 63. The water suction hose 8 is fixed to the side of the pump 4 away from the drain pipe 7, and the water suction hose 8 is sleeved on the winding roller 63. The mounting block 9 is a rectangular parallelepiped structure, and the mounting block 9 is fixedly sleeved on the end of the water suction hose 8 away from the pump 4. The bottom of the mounting block 9 is provided with a mounting groove 91, and the inner wall of the mounting groove 91 is provided with a sliding groove 92. The filter screen 10 is a mesh structure, and the filter screen 10 is arranged on the inner wall of the mounting groove 91. The cleaning brush 11 is arranged in the mounting groove 91, and the bristles of the cleaning brush 11 are pressed against the lower surface of the filter screen 10.

[0034] The driving assembly 12 is mounted on the mounting block 9 and is used to drive the cleaning brush 11 to move. The driving assembly 12 includes a slider 121, a waterproof motor 122, and a threaded rod 123. The slider 121 is a rectangular parallelepiped structure. The slider 121 is fixed on the side wall of the cleaning brush 11, and the slider 121 is slidably connected to the slide groove 92. The waterproof motor 122 is fixed on the side wall of the mounting block 9, and the output shaft of the waterproof motor 122 penetrates the side wall of the mounting block 9 and is rotatably connected. The threaded rod 123 is a horizontally arranged rod-shaped structure. The threaded rod 123 penetrates and is threadedly connected on the slider 121. One end of the threaded rod 123 is fixed to the end of the output shaft of the waterproof motor 122, and the other end of the threaded rod 123 is rotatably connected to the inner wall of the slide groove 92, and the axis of the threaded rod 123 coincides with the axis of the output shaft of the waterproof motor 122.

[0035] When the foundation pit needs to be drained, the staff moves the bottom plate 1 to a suitable position by pushing the frame 3, and then adjusts the length of the suction hose 8 by the hand wheel 62, so that the suction hose 8 enters the water in the foundation pit, and the water in the foundation pit is discharged through the pump 4. When the water flows into the suction hose 8, it is filtered through the filter 10, which reduces the probability of mud and sand clogging the suction hose 8 or even damaging the pump 4. When pumping water for a long time, mud and sand are easy to clog the filter. At this time, the staff drives the threaded rod 123 to rotate through the waterproof motor 122. Since the threaded rod 123 is threadedly connected to the slider 121, and the slider 121 is slidably connected to the slide groove 92, the slider 121 moves axially along the threaded rod 123, thereby driving the cleaning brush 11 to brush the surface of the filter 10, reducing the probability of mud and sand clogging the mesh of the filter 10.

[0036] In order to facilitate the smooth progress of drainage, the area of ​​a mesh hole on the filter 10 is 1-2 square millimeters. The mesh hole is set to an area of ​​1-2 square millimeters, which is conducive to the filter 10 to intercept small particles of mud and other impurities, thereby reducing the probability of mud, sand, gravel and other particles entering the drainage hose and causing blockage, thereby facilitating the smooth progress of drainage.

[0037] In order to protect the waterproof motor 122, a waterproof protective shell 13 for covering the waterproof motor 122 is fixed to the side wall of the mounting block 9. The waterproof protective shell 13 provides waterproof protection for the waterproof motor 122, reducing the probability of the waterproof motor 122 being damaged by water or external forces.

[0038] In order to make the water suction hose 8 sink quickly to the predetermined depth, a counterweight block 14 is fixedly sleeved on the side wall of the mounting block 9. The counterweight block 14 increases the weight of the mounting block 9, thereby facilitating the water suction hose 8 with adjusted length to sink quickly to the predetermined depth.

[0039] In order to reduce the probability of the rotating shaft 61 rotating automatically, a positioning assembly 15 is installed on the rotating shaft 61, and the positioning assembly 15 includes a positioning nut 151 and an annular gasket 152. The positioning nut 151 is sleeved on the rotating shaft 61 and threadedly connected to the rotating shaft 61, and the axis of the positioning nut 151 coincides with the axis of the rotating shaft 61. The annular gasket 152 is sleeved on the rotating shaft 61, and the annular gasket 152 is arranged between the positioning nut 151 and the mounting plate 5. After the staff has adjusted the length of the water suction hose 8, the staff needs to tighten the positioning nut 151 so that the side wall of the positioning nut 151 cooperates with the side wall of the mounting plate 5 and presses against the annular gasket 152, thereby limiting the rotation of the rotating shaft 61, thereby reducing the probability of the water suction hose 8 moving due to the automatic rotation of the rotating shaft 61. The annular gasket 152 is made of rubber material, and its surface has a large friction coefficient, which increases the friction between the side wall of the positioning nut 151 and the side wall of the mounting plate 5, and reduces the probability of the positioning nut 151 rotating. In addition, the annular gasket 152 also reduces the wear between the side wall of the positioning nut 151 and the side wall of the mounting plate 5.

[0040] The use principle of a water conservancy construction drainage equipment in the present embodiment is as follows: when it is necessary to drain the foundation pit, the staff moves the bottom plate 1 to a suitable position by pushing the frame 3, and then adjusts the length of the water suction hose 8 by the hand wheel 62, so that the water suction hose 8 enters the water in the foundation pit, and the water in the foundation pit is discharged through the pump 4. When the water flow enters the water suction hose 8, it is filtered through the filter 10, which reduces the probability of mud and sand clogging the water suction hose 8 or even damaging the pump 4. When pumping water for a long time, mud and sand are easy to clog the filter. At this time, the staff drives the threaded rod 123 to rotate through the waterproof motor 122. Since the threaded rod 123 is threadedly connected to the slider 121, and the slider 121 is slidably connected to the slide groove 92, the slider 121 moves axially along the threaded rod 123, thereby driving the cleaning brush 11 to scrub the surface of the filter 10, reducing the probability of mud and sand clogging the mesh of the filter 10.
