Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pits, and particularly relates to a device for draining water in a building foundation pit. Background Art

[0002] When it rains or there is a lot of groundwater, there will be a lot of accumulated water inside the foundation pit, and the accumulated water will cause the water content of the surrounding soil to increase, resulting in a decrease in the strength of the soil. If the water is not drained in time, the soil around the foundation pit is prone to collapse under the action of its own gravity and external loads, endangering the safety of construction workers and surrounding buildings.

[0003] Currently, when draining the water inside the foundation pit, a water pump is basically used to pump it out of the foundation pit. However, most of the existing water pumps have a mesh cover or are directly used at the water intake. When sinking into the foundation pit, it is easy to touch the bottom, and then be buried at the bottom of the foundation pit, causing the water pump to be blocked; in addition, since the accumulated water in the foundation pit is often relatively turbid and contains some impurities and silt, it will cause the water intake on the pipeline to be blocked, thus affecting the drainage work. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that most of the existing water pumps are provided with a mesh cover at the water intake. When sinking into the foundation pit, it is easy to touch the bottom, and then be buried at the bottom of the foundation pit, causing the water pump to be blocked. Moreover, the accumulated water in the foundation pit is often relatively turbid and contains some impurities and silt, which will cause the water intake on the pipeline to be blocked.

[0005] To solve the above technical problems, the technical solution provided by the utility model is a device for draining water in a building foundation pit, including a water pump body. The water intake end of the water pump body is connected with a water suction pipe, and a sealing head is arranged at one end of the water suction pipe. The water suction pipe is connected with a filtering mechanism, which is composed of an overall bracket and movable filter plates symmetrically arranged on both sides of the overall bracket. The overall bracket is in an overall U-shaped frame structure, and a bottom filter plate is arranged at the bottom of the overall bracket at the opening of the U-shaped structure. A water guide pipe is arranged in the middle of the overall bracket, and a plurality of water inlets are arranged at the bottom of the water guide pipe. A connecting seat is arranged above the water guide pipe on the overall bracket. The sealing head is inserted into the connecting seat, and a fixing cap is connected to the outside of the connecting seat by a thread; on both sides of the movable filter plates, both sides are slidably connected with both sides of the U-shaped structure of the overall bracket through guiding sliders. Force-bearing plates are arranged on one side of the guiding sliders at both ends of the movable filter plates, and telescopic cylinders are connected to the bottom of the force-bearing plates on the inner side of the overall bracket.

[0006] Preferably, positioning grooves are arranged on both sides of the connecting seat, and corresponding positioning blocks are arranged on both sides of the sealing head at the positioning groove positions.

[0007] Preferably, the top of the fixing cap is a limiting structure that slopes inward from the edge, and the inner diameter of the top of the fixing cap is the same as the outer diameter of the sealing head. An installation opening staggered with the positioning groove is provided at the top of the fixing cap.

[0008] Preferably, the length of the water guide pipe is less than or equal to the length between the overall support and the bottom filter plate.

[0009] Preferably, the width of the movable filter plate matches the width of the overall support, and the length of the movable filter plate is greater than the length of the overall support. The length by which the movable filter plate is greater than the overall support matches the distance that the telescopic cylinder extends.

[0010] Preferably, the length of the force-bearing plate is less than 1 / 2 of the thickness of the overall support, and the diameter of the connected telescopic cylinder is less than 1 / 2 of the thickness of the overall support.

[0011] Preferably, a sealing box is provided at the inner side of the overall support where the telescopic cylinder is located.

[0012] The advantages of the present utility model compared with the prior art are as follows:

[0013] The equipment for foundation pit drainage of the present utility model is provided with a filtering mechanism for extending the pumping length at the water pump suction pipe, thereby avoiding the suction port being buried in the bottom of the foundation pit during operation. Through the movable filter plates arranged on both sides, impurities and silt can be filtered. At the same time, due to the extension and retraction of the telescopic cylinder, the movable filter plates can move up and down, thereby flushing in the water of the foundation pit, effectively reducing impurities, silt, etc. attached to the movable filter plates.
