Description

Sump drainage device

Technical Field

The utility model relates to the field of water supply and drainage equipment, in particular to a sump drainage device.

Background

When the foundation pit is excavated in the building engineering, if the underground water level is higher, and the base elevation is below the underground water level, a drainage mode needs to be set. The water collecting pit is a simple and convenient mode and is suitable for the condition that the buried depth of the substrate is less than 5 m. The water collecting pit drainage method, also known as Ming drainage method, is to set a water collecting pit at the bottom of the pit, and to excavate a drainage ditch along the periphery or center of the pit bottom to make water flow into the water collecting pit, and then to pump away the water by a sewage pump (submersible sewage pump). The pumped water should be led to a place far away from the foundation pit so as to prevent the pumped water from flowing back into the foundation pit. When construction is carried out in rainy season, a intercepting ditch is excavated or a soil dike is built around a foundation pit or at the upstream of ground water so as to prevent the ground water from flowing into the foundation pit. The method is suitable for coarse-grained soil layers and also for clay layers with low water permeability.

In the prior art, a drainage pump is directly placed in a water collection pit, the drainage pump is easily damaged when being positioned in the water collection pit for a long time, the directly placed drainage pump is positioned at the bottom of the water collection pit, and sediment and dregs deposited at the bottom easily cause blockage of the drainage pump.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

The utility model provides a sump pit drainage device, includes sump pit 1, be provided with elevating gear 3 on the 1 inner wall of sump pit, elevating gear 3 includes lifter plate 6, rope 7, power unit 2, locking mechanism 205, demountable installation has drain pump 5 on the lifter plate 6, be provided with the spout 8 of vertical direction on the inner wall of sump pit 1, lifter plate 6 and spout 8 sliding connection, the one end and the lifter plate 6 of rope 7 are connected, the other end and the power unit 2 of rope 7 are connected.

Further, power unit 2 includes rocking arm 201, pivot 204, fixed block 202, support 203 is fixed by sump 1, support 203 and fixed block 202 fixed connection, pivot 204 runs through fixed block 202 and rotates with fixed block 202 to be connected, pivot 204 one end is connected with rocking arm 201, pivot 204 is connected with rope 7.

Further, the locking mechanism 205 includes a fixing shaft 207, a plurality of through holes 206 are formed in the fixing block 202 around the rotating shaft 204, and the through holes 206 are detachably connected to the fixing shaft 207.

Further, the device also comprises a cover plate 9, and the cover plate 9 is positioned at the upper part of the water collecting pit 1.

Further, the cover plate 9 is a net-shaped steel cover plate and a cement cover plate.

Further, the rope 7 is a hemp rope or a nylon rope.

Further, a net-shaped metal protective cover is arranged at the water inlet of the drainage pump 5.

Further, the drainage pump 5 is an electric submersible pump with the model number of WQ12-33-4 KW.

According to the sump drainage device provided by the utility model, when the sump 1 needs to pump water, the drainage pump 5 is started, the rocker arm 201 on the power mechanism 2 is rotated, the rope 7 wound on the rotary pump 204 is released, the lifting plate 6 starts to descend under the influence of gravity under the condition that the lifting plate 6 is not pulled by the rope 7, and people can slowly rotate the rocker arm 201 to avoid damaging the drainage pump 5. When the lifting plate 6 is placed at half height of the sump 1, the fixing shaft 207 is inserted into the through hole 206 nearest to the rocker arm 201, people should pay attention to the direction, the direction is the direction in which the rocker arm 201 puts down the lifting plate 6 to rotate, the fixing shaft 207 is used for blocking the autorotation of the rocker arm 201 driven by the gravity of the lifting plate 6, after the rocker arm 201 is locked, the lifting plate 6 is located in the clear middle part, the work in the place where bottom silt is mainly gathered is avoided, the risk of blockage of the drainage pump 5 is reduced, the drainage pipe 4 of the drainage pump 5 extends out of the water surface to complete drainage, after the drainage of the water surface is gradually reduced, the height of the lifting plate 6 can be properly reduced again until the water surface is close to the bottom, and the operation is stopped. At the in-process of sump pit 1 ponding again, rotate rocking arm 201, slowly twine rope 7 in pivot 204, lifter plate 6 also upwards moves under the pulling force effect of rope 7, until shifting out sump pit 1, at this moment sump pit 1 can't influence drain pump 5 at the water of ponding in-process, has avoided drain pump 5's corruption, has prolonged the life of drain pump greatly.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
