[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a water supply and drainage device for a deep foundation pit.

[0027] The utility model provides Figure 1-3 A water supply and drainage device for a deep foundation pit shown in the figure includes a drainage shell 1, first filter screens 2 are fixedly penetrated on the upper ends of both sides of the drainage shell 1, collecting boxes 3 are contacted on the lower ends of both sides of the drainage shell 1, mounting plates 25 are fixedly provided at the bottoms of the two collecting boxes 3, mounting bolts 26 are threadedly provided between the mounting plates 25 and the drainage shell 1, through holes are opened at the lower ends of the collecting boxes 3, second filter screens 4 are fixedly penetrated on the lower ends of both sides of the drainage shell 1, and the second filter screen 4 is arranged in cooperation with the through holes, a water pump 5 is fixedly provided on the inner wall of the drainage shell 1, a water suction pipe 6 is fixedly penetrated inside the water pump 5, the upper end of the water suction pipe 6 passes through the drainage shell 1 and extends to the outside, and cleaning brushes 7 are contacted on the sides away from the two first filter screens 2.

[0028] When draining the inside of the foundation pit, the drainage shell 1 is placed inside the foundation pit, so that the water inside the foundation pit enters the drainage shell 1 through the first filter screen 2, and the water is sucked to the outside of the foundation pit through the water pump 5 and the suction pipe 6. While draining, the cleaning brush 7 starts to move, so that the cleaning brush 7 moves longitudinally and pushes and cleans the impurities accumulated on the outside of the first filter screen 2. At the same time, the cleaning brush 7 can push the impurities into the collection box 3, remove the impurities, reduce the accumulation of impurities inside the foundation pit, and ensure that impurities cannot accumulate in large quantities on the outside of the first filter screen 2, thereby ensuring that the water can stably and normally enter the drainage shell 1 and be discharged.

[0029] In order to drive the cleaning brush 7 to reciprocate during the drainage process, as shown in FIG. Figure 1-3 As shown, a pushing cleaning mechanism is provided on the top of the cleaning brush 7, and the pushing cleaning mechanism includes a double-axis motor 8, which is fixedly arranged on the top of the drainage housing 1, and cross bars 9 are fixedly arranged on the output ends on both sides, and a waterproof cover 24 is fixedly arranged on the top of the drainage housing 1, and the waterproof cover 24 is arranged on the outside of the double-axis motor 8 and is rotatably sleeved on the outside of the cross bar 9, and a rotating plate 10 is fixedly arranged on one end of the two cross bars 9 away from each other, and a connecting rod 11 is fixedly arranged on the side wall of the rotating plate 10, and a push plate 12 is rotatably sleeved on the outside of the connecting rod 11;

[0030] A support rod 13 is rotatably sleeved at the inner lower end of the push plate 12, and connecting plates 14 are fixedly provided at both ends of the support rod 13. A connecting frame 15 is fixedly provided at the bottom of the two connecting plates 14. The inner wall of the connecting frame 15 is fixedly connected to the cleaning brush 7 through a telescopic rod 16, and a spring 17 is sleeved at the sleeve end of the telescopic rod 16. A vertical rod 18 is fixedly provided on the top of the collecting box 3, and a slide plate 19 is slidably sleeved on the rod wall of the vertical rod 18, and the slide plate 19 is fixedly connected to the connecting frame 15.

[0031] While drainage is in progress, the dual-axis motor 8 starts working, causing the two cross bars 9 to rotate. At this time, the rotating plate 10 rotates. Through the connection between the rotating plate 10 and the connecting rod 11, the connecting frame 15 can drive the cleaning brush 7 to move longitudinally under the support of the vertical rod 18 and the slide plate 19. At the same time, under the elastic support of the telescopic rod 16 and the spring 17, the cleaning brush 7 can push down the impurities on the outside of the first filter screen 2 and stably push the impurities into the collection box 3. Since the rotating plate 10 continues to rotate and the support rod 13 and the push plate 12 rotate relative to each other, the connecting frame 15 can drive the cleaning brush 7 to move back and forth longitudinally to effectively clean the impurities.

[0032] In order to avoid the backflow of impurities and the overflow of impurities after they are pushed into the collecting box 3, Figure 1-2As shown, a fixing rod 20 is fixedly provided at the upper end of the inner wall of the collecting box 3, a baffle 21 is rotatably sleeved on the rod wall of the fixing rod 20, a torsion spring 22 is sleeved on the rod wall of the fixing rod 20, two ends of the torsion spring 22 are respectively fixedly connected to the baffle 21 and the fixing rod 20, a limiting plate 23 is provided in contact with the top of the baffle 21, and the limiting plate 23 is fixedly connected to the inner wall of the collecting box 3.

[0033] When the cleaning brush 7 pushes the impurity soldier down to contact the collection box 3, the cleaning brush 7 pushes the baffle 21, causing the baffle 21 to rotate around the fixed rod 20 and twist the torsion spring 22. At this time, the cleaning brush 7 can drive the impurities into the collection box 3, so that the impurities can enter the collection box 3 stably. When the cleaning brush 7 moves upward, with the cooperation of the torsion spring 22 and the limit plate 23, the baffle 21 rebounds to its original position and seals the top of the collection box 3 to minimize the backflow of impurities and overflow.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
