Description

Technical Field

[0001] The utility model belongs to the field of foundation pit drainage devices, in particular to a foundation pit drainage anti-blocking device. Background Art

[0002] The pump is one of the important facilities for foundation pit drainage. The water in the foundation pit is pumped out by the pump to ensure that the foundation pit can remain dry, stable and safe during the construction process. However, due to the presence of particles such as silt in the foundation pit, the pump is prone to sucking in silt while pumping out the water, which can easily cause the pump to become blocked. Therefore, a filter screen or other device is usually used to filter the water to prevent the pump from being blocked by silt and affecting the construction progress.

[0003] According to Chinese patent application No.: 202320429909.3, an anti-blocking foundation pit drainage device is disclosed, wherein a drainage pump is arranged inside the drainage box, a water inlet end of the drainage pump is connected to a connecting pipe and one end of the connecting pipe passes through one side of the drainage box, a water outlet end of the drainage pump is connected to an outlet pipe and one end of the outlet pipe passes through the other side of the drainage box, an inlet pipe is arranged at one end of the connecting pipe, an anti-blocking component is installed at the upper end of the inlet pipe, the anti-blocking component includes a connecting plate installed on the upper surface of the inlet pipe by screws, a crushing motor is arranged on the upper surface of the connecting plate; a filtering component is arranged on the lower surface of the inlet pipe, and when the crushing motor is working, the crushing blade arranged outside the rotating shaft will crush the mud or sand and gravel impurities entering the inlet pipe, so as to avoid the impurities from entering the inlet pipe and the connecting pipe and causing blockage, thereby affecting the drainage of the foundation pit;

[0004] The comparative case effectively solves the problem that the filter screen of the foundation pit drainage device in the prior art is prone to clogging, and has the advantage of being able to prevent impurities from entering the water inlet pipe and avoiding clogging of the foundation pit drainage device. Although this anti-clogging device can achieve anti-clogging effects through crushing and cleaning, the inlet of the water inlet pipe can only clean the debris on its surface through the cleaning plate, so that the debris will continue to be adsorbed on the surface of the filter screen, and the debris cannot be thoroughly cleaned, which is prone to clogging.

The debris is blocked by the filter assembly 312 and adsorbed on the surface of the filter screen. The servo motor 321 drives the main shaft 322 to rotate, so that the crushing knife 323 can crush the smaller debris such as mud and sand entering the inner cavity of the tube body 311.

The servo motor 321 drives the main shaft 322 to rotate, so that the crushing knife 323 can crush the silt and other smaller particles entering the inner cavity of the pipe body 311. When the scraper 331 is in contact with the filter screen, the scraper 331 can clean the filter screen while rotating. When the scraper 331 rotates, the connecting rod 334 can also be used to drive the crushing knife 332 to rotate, so that the crushing knife 332 can crush the debris adsorbed on the surface of the filter screen, thereby cleaning the debris and preventing the debris from being adsorbed on the surface of the filter screen and affecting the drainage efficiency. After the debris crushed by the crushing knife 332 enters the inner cavity of the tube body 311, it is crushed again by the crushing knife 323, thereby preventing the debris and sand from clogging the drainage component 2.
