[0002] A lot of rainwater will accumulate in the building foundation pit on rainy days, and water pumping equipment is needed to extract the water in the foundation pit. In order to facilitate the movement of the extraction position, the existing water pumping equipment will set the pumping tank on a cart. The water tank is provided with a filtering structure to filter and intercept the sediment in the water. However, when cleaning the internal filter, it is necessary to disassemble the filter box and take out the internal filter for cleaning. The cleaning is inconvenient and the practicality is poor. For this reason, we propose a water pumping equipment with a filtering structure.

Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a technical solution: a water extraction device with a filtering structure, comprising a cart 1, a water tank 2 is fixedly installed on the top of the cart 1, a pump body 3 is fixedly installed on the top of the water tank 2, a filter box 4 is fixedly installed on the top of the water tank 2, a water extraction pipe 5 is embedded on the top of the filter box 4, the input end of the pump body 3 is embedded in the bottom of the filter box 4, a cleaning port 6 is provided on the front side of the bottom of the filter box 4, a sealing plate 7 is attached to the front side of the bottom of the filter box 4, mounting holes are provided at the four corners of the sealing plate 7, bolts are provided in the mounting holes, the top ends of the bolts are screwed to the bottom of the filter box 4, a through hole is provided on the left side wall of the filter box 4, a rotating sealing ring 10 is provided in the through hole, a rotating rod 8 is provided in the filter box 4, the right end of the rotating rod 8 is rotatably connected to the right side wall of the inner part of the filter box 4 through a bearing, a filter screen 9 is fixedly installed on the side wall of the rotating rod 8, the left end of the rotating rod 8 passes through the rotating sealing ring 10 and extends to the outside, and the middle part of the front side of the bottom of the filter box 4 is in an empty state;

[0020] A drain pipe with a switch valve may also be provided on the side wall of the water tank 2 .

[0021] The pumping pipe 5 is a hose, which is convenient for workers to hold the end and move it to the pumping position in the foundation pit.

[0022] A cross bar 11 is fixedly installed on the left end of the rotating rod 8, and vertical plates 12 are integrally formed at the upper and lower ends of the side walls of the cross bar 11. A spring 13 is fixedly installed on the left side of the vertical plate 12, and a connecting plate 14 is fixedly installed on the left end of the spring 13. A cross column 15 is fixedly installed on the inner end of the connecting plate 14. A slide groove 16 is provided on the right end of the cross column 15. The inner side wall of the slide groove 16 is slidably installed on the side wall of the cross bar 11. An L-shaped rod 17 is fixedly installed on the top of the side wall of the cross column 15. A positioning groove 18 is provided on the outer left side wall of the filter box 4. The spring 13 is in an extended and elongated state, and the right end of the L-shaped rod 17 is inserted into the positioning groove 18.

[0023] Figure 2 , 4 In the embodiment, since the rotating rod 8 and the cross bar 11 cannot move left and right, the spring 13 can cause the cross column 15 to have a rightward pressure, thereby causing the right end of the L-shaped rod 17 to be inserted into the positioning groove 18. Figure 3 The position of the middle filter screen 9 is positioned.

[0024] Specifically, the cross bar 11 is a square bar, and the inner side wall of the slide groove 16 is a square shape matching the cross bar 11 .

[0025] By configuring the cross bar 11 to be in a square bar shape, the cross bar 11 and the rotating rod 8 can be driven to rotate simultaneously when the cross column 15 is rotated, thereby preventing the spring 13 from being twisted radially.

[0026] Specifically, a rubber pad 19 is fixedly mounted on the top of the sealing plate 7 , and the top of the rubber pad 19 is tightly fitted to the bottom of the filter box 4 .

[0027] The rubber pad 19 is used to increase the sealing effect of the cleaning port 6 .

[0028] Specifically, a rectangular ring 20 is integrally formed on the inner wall of the filter box 4 , and the rectangular ring 20 is located on the upper side of the filter screen 9 .

[0029] The rectangular ring 20 can shield the gap between the filter screen 9 and the inner wall of the filter box 4 to prevent water from falling through the gap.

[0030] Specifically, the top of the rectangular ring 20 is provided with an inner concave surface 21 .

[0031] The provision of the inner concave surface 21 can prevent sewage from accumulating on the top of the rectangular ring 20 .

[0032] Specifically, a push frame 22 is fixedly installed on the top left side of the cart 1.

[0033] Working principle: The staff pushes the whole device to the periphery of the foundation pit, then moves the end of the hand-held pumping pipe 5 to the position in the foundation pit to be pumped, turns on the pump body 3, and the pump body 3 generates suction to extract the accumulated water in the foundation pit through the pumping pipe 5. The accumulated water enters the filter box 4, and the sediment can be intercepted by the filter screen 9. The filtered water enters the water tank 2 through the pump body 3;

[0034] When the filter screen 4 needs to be cleaned, the sealing plate 7 and the filter box 4 can be disassembled to open the cleaning port 6, and then the cross column 15 is moved to the left to make the L-shaped rod 17 disengage from the positioning groove 18, and then the cross column 15 is rotated to drive the cross bar 11 and the rotating rod 8 to rotate, so that the filter screen 4 can be cleaned. Figure 3 The left end of the middle filter 9 is rotated to the cleaning port 6 to clean it. Figure 3 The front and rear length of the middle cleaning port 6 can be set a little longer, which is convenient for the staff to operate and clean.
