Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering and construction, in particular to an anti-blocking device for a fine sand foundation pit drainage pump. Background Art

[0002] Deep excavations in industrial buildings, such as thermal power plants, often require drainage. Conventional drainage methods involve placing a drainage pump directly into a sump. However, this traditional method has drawbacks: large amounts of sediment entering the pump can easily clog it, causing it to burn out, impacting drainage efficiency and posing a significant risk to site safety. Therefore, we have developed an anti-clogging device for fine sand foundation pit drainage pumps to address these issues. Utility Model Content

[0003] The purpose of the utility model is to provide an anti-blocking device for fine sand foundation pit drainage pumps, so as to solve the problem proposed in the above background technology that a large amount of mud and sand in the water enters the pump, which can easily block the drainage pump, causing the pump to burn out, affecting the foundation pit drainage efficiency, and posing a greater risk to on-site safety.

[0004] To achieve the above object, the present invention provides the following technical solution: a device for preventing blockage of a fine sand foundation pit drainage pump, comprising a drag box, wherein a cavity is integrally formed inside the drag box, and the upper end of the cavity is open;

[0005] Also includes:

[0006] A water inlet is provided on the surface of the drag box. There are several water inlets evenly distributed on the surface of the drag box, and the water inlets are connected to the inside of the cavity. A sand-proof net is provided on the surface of the drag box, and the sand-proof net is nested around the outside and bottom of the drag box. A horizontal board is placed on the upper end of the drag box, and a rope is wrapped around the surface of the horizontal board. A water pump is movably placed inside the drag box, and the other end of the rope is connected to the water pump.

[0007] Preferably, the surface of the inner cavity of the drag box is integrally formed with a reinforcement wall.

[0008] Preferably, a first fixing bracket is installed at the upper end of the inner cavity of the tow box, a limit block is provided on the surface of the inner cavity of the tow box, and the first fixing bracket is attached to the upper end surface of the limit block, and a second fixing bracket is movably installed at the bottom end of the inner cavity of the tow box.

[0009] Preferably, fixed frames are symmetrically provided on both sides of the upper end of the drag box, and the two ends of the transverse plate are movably engaged in the interior of the two fixed frames.

[0010] Preferably, a bottom plate is movably placed at the inner bottom end of the drag box, and a handle is provided at the upper end of the bottom plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. By setting up a drag box, placing the water pump in the inner cavity of the drag box, and setting several water inlets on the surface of the drag box, and covering the outside of the drag box with a layer of spinning net, the drag box equipped with the water pump is placed in the foundation pit, and the accumulated water enters the interior of the drag box from the water inlet, and is extracted by the water pump, while the impurities, sediment and larger particles in the water will be intercepted by the sand control net. Only water can pass through the sand control net and enter the interior of the drag box from the water inlet to be extracted by the water pump, thereby reducing the situation where a large amount of sediment enters the water pump and causes damage to the pump body.

[0013] 2. By setting a horizontal board on the drag box and connecting the water pump and the horizontal board with a rope, the water pump can be placed and fixed. When it is not needed, the water pump can be taken out from the inside of the drag box by lifting the horizontal board, which makes it convenient for the staff to take and place the water pump. At the same time, a bottom plate is placed at the bottom end of the inside of the drag box, and a handle is set on the surface of the bottom plate. When the drag box is taken out of the water after the extraction is completed, the bottom plate can be taken out from the inside of the drag box. The bottom plate brings out the residual mud and sand inside the drag box, which makes it convenient to clean the inside of the drag box. BRIEF DESCRIPTION OF THE DRAWINGS
