Its function is to absorb and buffer the structural deformation caused by temperature changes, equipment vibration and other factors, and it undertakes important tasks such as regulating water flow, flood control and drainage. However, there are often water seepage problems at the expansion joints of existing pump station plants, which not only affects the normal operation of the plant, but may also have adverse effects on environmental sanitation. In order to solve this technical problem, a drainage component 2 is added on this basis.

[0026] More specifically:

Its function is to absorb and buffer the structural deformation caused by factors such as temperature changes and equipment vibration. However, the existence of expansion joints may also cause water infiltration problems, posing a potential threat to the normal operation of the pump station. By using arc-shaped stainless steel grooves to seal the expansion joints, it can better adapt to the deformation of the expansion joints and ensure the sealing effect. At the same time, stainless steel materials have good corrosion resistance and durability, and can maintain sealing performance for a long time, effectively preventing water from penetrating into the pump station through the expansion joints. The staff uses a cutting machine to cut a 3*3 cm groove along the wall. The depth and width of the groove ensure that the fixing part 21 can be smoothly installed and fixed therein. The fixing part 21 is an internal hollow cylindrical structure. A fixing chuck 23 is inserted into the inside of the fixing part 21. A plurality of rectangular grooves 24 are provided in an annular manner on the inner side of the end of the fixing chuck 23, which can allow the fixing chuck 23 to deform to a certain extent. The conical groove 26 provided on the inner side of the end of the rotating cover 22 is a conical structure. The inner wall surface of the conical groove 26 provided on the rotating cover 22 is in contact with the truncated cone structure at the end of the fixing chuck 23. By rotating the rotating cover 22 on the inner side of the end of the fixing part 21, The rotating cover 22 is rotated to move toward the inside of the fixing member 21, and then the conical groove 26 opened in the rotating cover 22 squeezes the end of the fixing chuck 23, so that the fixing chuck 23 clamps the rod-shaped structure at the end of the fixing ring 25, and the guide tube 1 can be fixed. The rotating cover 22 is rotated in the opposite direction to reduce the pressure of the rotating cover 22 on the end of the fixing chuck 23, thereby reducing the pressure of the inner side of the end of the fixing chuck 23 on the outer side of the end of the fixing ring 25, so as to realize the rapid disassembly of the guide tube 1. The function of the guide tube 1 is to remove the infiltrated The water flow entering the pump station is guided to the collection bucket 27 placed at the preset water pump layer. The installation of the guide pipe 1 can ensure that the water can flow smoothly into the collection bucket 27 to avoid the water flow being retained inside the pump station or causing other safety hazards. The fixing ring 25 and the guide pipe 1 can be quickly installed and disassembled by rotating the rotating cover 22, which is convenient for the staff to disassemble and maintain the guide pipe 1 at a later stage. When the guide pipe 1 is damaged, the guide pipe 1 can be disassembled in time to reduce the economic losses caused by the damage of the guide pipe 1.

[0031] In an optional embodiment, a booster rod 28 is rotatably connected to the inner side of the end of the rotating cover 22 .

[0032] In the present embodiment: an assist rod 28 is rotatably connected to the outer side of the end of the rotating cover 22. The assist rod 28 is a rod-shaped structure. The staff can rotate the assist rod 28 to make the assist rod 28 and the rotating cover 22 be in the same horizontal plane. The staff can hold the assist rod 28 to rotate the rotating cover 22, and then disassemble the guide tube 1 more labor-savingly, thereby increasing the work efficiency of the staff. At the same time, when the assist rod 28 is not needed, the assist rod 28 can be rotated to be perpendicular to the rotating cover 22 and stored, thereby saving the space occupied by the assist rod 28 and increasing the practicality of the device.

[0033] Going further:

[0034] In an optional embodiment, the outer side of one end of the fixing clamp 23 is annularly fixedly connected to the limiting block 29 , and the inner side of the end of the fixing member 21 is annularly provided with a limiting groove 210 .

[0035] In the present embodiment: the outer side of the end of the fixing chuck 23 is annularly fixedly connected to the limiting block 29, and the inner side of the end of the fixing piece 21 is annularly provided with a limiting groove 210. When the staff inserts the fixing chuck 23 into the fixing piece 21, the limiting block 29 is correspondingly inserted into the limiting groove 210 provided in the fixing piece 21, so that when the staff rotates the rotating cover 22, the fixing chuck 23 will not be driven to rotate, thereby increasing the squeezing efficiency of the fixing chuck 23, and can increase the fixing efficiency of the rod-shaped structure at the end of the fixing ring 25.

[0036] Going further:

[0037] In an optional embodiment, a plurality of cement casting grooves 211 are provided on the outer side of the end of the fixing member 21 .

[0038] In this embodiment: a plurality of cement casting grooves 211 are opened on the inner side of the end of the fixing piece 21. The staff installs the fixing piece 21 inside the groove opened in the wall, and then injects cement into the groove. At the same time, the cement can penetrate into the cement casting groove 211 opened by the fixing piece 21, thereby increasing the firmness of the fixing piece 21 and preventing the fixing piece 21 from falling off from the groove.

A plurality of cement casting grooves 211 are provided on the inner side of the end of the fixing part 21. The staff installs the fixing part 21 inside the groove provided in the wall, and then injects cement into the groove. At the same time, the cement can penetrate into the cement casting groove 211 provided in the fixing part 21, thereby increasing the firmness of the fixing part 21 and preventing the fixing part 21 from falling off from the groove. A protective elbow 212 is provided at the bend of the guide tube 1. The protective elbow 212 is a thickened fixing device.
