[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, a deep foundation pit drainage device for building construction includes: a pump body 1 for pumping water; a filter shell 2 located at the bottom of the pump body 1; a collection box 3 detachably connected to the end of the filter shell 2; a locking assembly 4 connecting the collection box 3 and the filter shell 2; and a fixing mechanism 5 located on the side wall of the filter shell 2.

[0024] When water accumulates in the foundation pit, this device is placed into the water. This device will drain the water and filter out large particles of mud and sand, ensuring the safe use of the pump body 1. The pump body 1 in this device is preferably a submersible pump.

[0025] The filter housing 2 is used for preliminary filtration of accumulated water to prevent large particles of stone from being sucked into the pump body 1. The filter housing 2 is detachably connected to the pump body 1. Two connecting columns 21 are provided at the top of the filter housing 2, pointing vertically upwards. Two connecting plates 11 are provided on the side wall of the pump body 1. The connecting columns 21 pass through the connecting plates 11, thereby restricting the rotation of the connecting plates 11 and the pump body 1. Nuts 211 are screwed onto the connecting columns 21, with the bottom of the nuts 211 pressing against the upper part of the connecting plates 11, thus connecting the pump body 1 and the filter housing 2. The pump body 1 then pumps out the water that has entered the filter housing 2. The nuts 211 and the connecting columns 21 are treated with galvanizing and painting for rust prevention, and are regularly maintained and rust-proofed.

[0026] The bottom of the pump body 1 extends into the filter housing 2. The pump body 1 pumps the water that has entered the filter housing 2 into the collection pit. The outlet of the pump body 1 is located outside the filter housing 2. A drain pipe is connected to the outlet of the pump body 1. The drain pipe extends to the nearby collection pit, thereby realizing the transfer of water.

[0027] The filter housing 2 has a first filter screen 22 on both sides. Water enters the filter housing 2 through the first filter screen 22. The first filter screen 22 intercepts large stones. There are gaps between the large stones, which do not affect the normal water pumping operation. There are two sets of first filter screens 22, located on both sides of the pump body 1. The two sets of first filter screens 22 serve as backups for each other to ensure the normal operation of water pumping and filtration. The top of the filter housing 2 has two mounting holes 23, located on both sides of the pump body 1. The mounting holes 23 are located behind the first filter screen 22 and are rectangular through holes that penetrate the top of the filter housing 2.

[0028] like Figure 2 As shown, the collection box 3 is used to filter out smaller particles. The collection box 3 is detachably connected to the mounting hole 23. An opening 31 is provided on the side of the collection box 3 facing the first filter screen 22. Water that has passed through the first filter screen 22 enters the collection box 3 through the opening 31. A second filter screen 32 is provided on the side of the collection box 3 away from the opening 31. The aperture of the second filter screen 32 is smaller than that of the first filter screen 22. The second filter screen 32 filters the water again. While particles passing through the first filter screen 22 will not immediately have a fatal impact on the normal operation of the pump body 1, the second filter screen 32 intercepts even smaller impurities, further optimizing water quality and extending the service life of the pump body 1. By using the first filter screen 22 and the second filter screen 32 to filter impurities in the water in stages, it effectively prevents debris from clogging the water inlet channel, improving the smoothness of pumping water from deep foundation pits.

[0029] The collection box 3 is equipped with a separating block 33, which reduces the amount of impurities entering the collection box 3 and flowing out again. The separating block 33 spans the entire opening 31 and is fixed to the bottom of the opening 31. The side of the separating block 33 facing the first filter screen 22 is a slope, and the side of the separating block 33 facing the second filter screen 32 is a vertical surface. Small particles of debris entering the collection box 3 can overcome the slope under the impact of the subsequent water flow. When there is too much debris in the collection box 3, the collection box 3 is removed from the filter shell 2. When disassembling the collection box 3, the vertical surface blocks the debris, reducing the amount of debris that enters the filter shell 2 due to the shaking during the disassembly of the collection box 3, thereby further protecting the pump body 1. After the collection box 3 is removed, the debris intercepted by the second filter screen 32 can be emptied.

[0030] Locking component 4 is used to temporarily secure collection box 3. For example... Figure 3 As shown, the locking component 4 includes a connecting hole 41 and a folding pin 42. The connecting hole 41 is located on the top of the collection box 3 and on the outside of the collection box 3. The bottom of the folding pin 42 is located on the top of the filter shell 2. The folding pin 42 passes through the connecting hole 41 and can press the collection box 3 without upward external force.

[0031] The folding pin 42 includes a positioning block 421 and a bending block 422. The bottom of the positioning block 421 is fixed to the filter shell 2, and the top of the positioning block 421 is connected to the bending block 422 via a rotating shaft 423. Both the positioning block 421 and the rotating shaft 423 can pass through the connecting hole 41, and the height of the positioning block 421 is greater than the height of the connecting hole 41. When installing and removing the collection box 3, the bending block 422 is placed vertically so that both the bending block 422 and the positioning block 421 pass through the connecting hole 41. Then, the bending block 422 is rotated so that it is perpendicular to the positioning block 421. At this time, the bending block 422 is in contact with the top of the collection box 3, and the bending block 422 applies downward pressure to the collection box 3.

[0032] The fixing mechanism 5 temporarily fixes the filter shell 2 in the deep foundation pit where no foundation layer has been poured. For example... Figure 4 As shown, the fixing mechanism 5 includes a fixing block 51, a positioning cone 52, a spring 53, a pressing rod 54, and a protective shell 55. The fixing block 51 is fixedly connected to the side wall of the filter shell 2. The positioning cone 52 passes through the fixing block 51, and its bottom can be inserted into a deep pit. The spring 53 is located at the top of the positioning cone 52, and the pressing rod 54 is attached to the top of the spring 53. The protective shell 55 surrounds the spring 53, and the pressing rod 54 is screwed to the protective shell 55. In use, rotating the pressing rod 54 moves it downward, causing the spring 53 to contract, thereby allowing the positioning cone 52 to be inserted into the deep pit. The spring 53 can increase the downward pressure, making the filter shell 2 more securely fixed.

[0033] The lower part of the pressing rod 54 is threaded, while the upper part is a smooth round rod, allowing the worker to operate it in a standing position. The threads of the pressing rod 54 are regularly cleaned and rust-proofed.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
