Description

Technical Field

[0001] This utility model belongs to the field of deep foundation pit drainage technology, and in particular relates to a deep foundation pit drainage device. Background Technology

[0002] An excavation pit is an underground space excavated for the construction of a building's foundation and basement. During rainy days, water may accumulate in the excavation pit, which can affect its use. Therefore, it is necessary to drain the excavation pit.

[0003] For example, Chinese patent CN220352867U discloses a deep foundation pit drainage device, including a movable base plate and movable wheels disposed on the lower surface of the movable base plate. A water pump is fixed to the upper surface of the movable base plate by bolts. A water pump has a suction hose at its inlet and a drainage hose at its outlet, and a filter cylinder is disposed at the end of the suction hose furthest from the water pump. A winding mechanism for winding the suction hose and drainage hose is disposed on the upper surface of the movable base plate. The winding mechanism includes a mounting frame fixed to the upper surface of the movable base plate and a winding roller rotatably disposed on the inner wall of the mounting frame. Two symmetrical limiting discs are fixed to the outer surface of the winding roller. Compared with the prior art, this deep foundation pit drainage device effectively solves the defect of the prior art in being unable to automatically wind up the suction hose and drainage hose by setting up a winding mechanism, providing great convenience for operators.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has several drawbacks in use. For example, since it rests at the edge of the pit, the filter cartridge still requires manual placement by workers. It cannot automatically place the filter cartridge near the center of the pit, making it inconvenient to use. Furthermore, when the hollow positioning plate and filter cartridge are placed in the pit, both have a certain height. If the water level in the pit is below the rotating pipe, pumping will cease, resulting in a significant amount of water remaining in the pit and ineffective pumping. Therefore, we propose a deep pit drainage device. Utility Model Content

[0006] The purpose of this invention is to provide a deep foundation pit drainage device to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a deep foundation pit drainage device, including a movable base, and further comprising:

[0066] It is worth noting that the distance between the scraper 30 and the bottom of the pit is 2-3cm, so that the remaining small amount of water can seep into the soil of the pit and will not affect the normal use of the pit.

[0067] Working Principle: During use, the operator holds handle 5 and pushes the entire device to the edge of the pit, bringing the U-shaped frame 8 close to the pit. Then, the side of the movable base 1 furthest from the pit is fixed to the ground using two fixing nails to prevent tilting. The operator then powers on and starts the first servo motor 4. The output shaft of the first servo motor 4 drives the second bevel gear 22 to rotate. Under meshing action, the second bevel gear 22 drives the first bevel gear 21 to rotate. The first bevel gear 21 drives the threaded rod 19 to rotate. Under the action of the thread, the threaded rod 19 moves the T-shaped rod 6 on the guide rod 17. At this time, the U-shaped frame 8 will move towards the pit until it is directly above the pit. Then, the operator powers on and starts the second servo motor 9. The output shaft of the second servo motor 9 drives the rotating roller 10 to rotate. At this time, the second flexible hose 11, wrapped around the rotating roller 10, will slowly unfold under the gravity of the pumping pipe 12. The pumping pipe 12 will then move downwards until the pumping pipe... The pump 12 enters the water in the foundation pit, and the positioning cone 25 at the bottom of the pump 12 will insert into the soil at the bottom of the foundation pit. The limiting plate 27 will contact the bottom of the foundation pit, creating a gap between the scraper 30 and the bottom of the foundation pit. Then, the operator can power on and start the rotary motor 24, which will drive the scraper 30 to rotate. At the same time, the operator can power on and start the water pump 15. At this time, the water in the foundation pit will enter the pump 12. Under the action of the filter plate 26, the water in the water can be filtered. Impurities are cleaned, and the rotation of the scraper 30 prevents impurities from adhering to the filter plate 26, ensuring that water can smoothly enter the water pumping pipe 12 through the filter plate 26. Subsequently, the water in the water pumping pipe 12 will enter the second hose 11, the water in the second hose 11 will enter the through hole 28, the water in the through hole 28 will enter the fixed pipe 13, the water in the fixed pipe 13 will enter the first hose 7, and the water in the first hose 7 will be pumped by the water pump 15 to the drain pipe 16 and discharged to the outside of the pit.
