Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit anti-blocking devices, in particular to a foundation pit dewatering anti-blocking device. Background Technique

[0002] In order to prevent the foundation pit from accumulating water caused by rain or groundwater seepage, which affects the construction progress, a drainage system is usually set at the bottom of the foundation pit, and the accumulated water is discharged from the foundation pit through a water extraction pipe. However, since there is a lot of sediment at the bottom of the foundation pit, and there may even be construction waste, this may cause blockage during the drainage process. Therefore, a foundation pit dewatering anti-blocking device is needed to solve this problem.

[0003] After retrieval, a foundation pit dewatering anti-blocking device with the publication number CN220598554U includes a foundation pit body. Both ends of the foundation pit body are fixedly connected with enclosing plates. The tops of the two enclosing plates are both fixedly connected with adjusting plates. An adjusting block is installed between the two adjusting plates through an adjusting mechanism. The bottom end of the adjusting block is fixedly connected with a moving plate. Through the coordinated use of a first motor, a bidirectional screw rod, a rotating screw sleeve, an adjusting rod and a flipping rod, the adjusting block is driven to move. During the movement of the adjusting block, the moving plate will be driven to move, so as to lift the garbage inside the foundation pit body and improve the cleaning effect of the garbage inside the butt pit.

[0030] Working principle: First, through the filter screen inside the filter screen plate 12, the garbage can be retained on the upper side of the filter screen plate 12. The accumulated water filtered from the garbage is pumped into the drain pipe 14 by the water pump 13 and conveyed upward. Connect an external hose to the top end of the drain pipe 14 to drain the water to a designated position. When a certain amount of garbage has accumulated, start the double-shaft motor 8, so that the two transmission rods 9 drive the driving bevel gears 10 to rotate, thereby causing the two driven bevel gears 15 to drive the corresponding rotating rods 6 to rotate, and further causing the two spur gears 7 to rotate in opposite directions, resulting in the rack 4 sliding upward in the chute frame 3 and driving the filter screen plate 12 to move upward to the outside of the foundation pit main body 1, so that the staff can clean the retained garbage. Press both pressing blocks 18 into the connecting block 11 to squeeze the springs 19 and cause one end of the L-shaped insertion rod 20 to disengage from the slot 17, thereby releasing the limit on the filter screen plate 12. Then move the filter screen plate 12 upward to remove the filter screen plate 12 from between the two chute frames 3, so as to carefully clean the filter screen inside the filter screen plate 12, avoid excessive dirt on the filter screen, corrode the filter screen, and affect the service life of the filter screen.
