Technical Field
The invention relates to the field of constructional engineering equipment, and particularly discloses a foundation pit drainage device.
Background
The foundation pit is a space below the ground excavated for constructing a building foundation and a basement. Because the construction process of the foundation pit is long, and the building construction process is also long later, if the construction process meets rainwater weather, a large amount of water can be accumulated in the foundation pit, and great influence is caused on the construction, so that drainage work needs to be done after the foundation pit is constructed. In the prior art, a water pump is generally adopted for pumping water, impurities and sludge in water are easy to block when the water pump pumps water, so that water pumping is interrupted, and the efficiency is very influenced.
Disclosure of Invention
In view of the above, the present invention is directed to a foundation pit drainage device, so as to solve the technical problem that sludge in water is likely to cause blockage of a water pumping device.
In order to achieve the purpose, the invention provides the following technical scheme:
a foundation pit drainage device comprises a vertical rail arranged on the inner wall of a foundation pit and a drainer arranged on the vertical rail, wherein the drainer comprises a buoyancy bottom plate, an outer shell, a water pumping device and a filtering device; the buoyancy bottom plate is arranged at the bottom of the outer shell, the water pumping device is fixedly arranged in the outer shell, and a water inlet pipe and a water outlet pipe are arranged on the water pumping device; the outside of shell body is provided with the water installations of slope, the water installations incurve is formed with the water route, and water installations's upper end and inlet tube intercommunication, water installations's lower extreme are provided with the water inlet, and the water inlet flushes with the side of buoyancy bottom plate, filter equipment sets up on the water inlet.
Optionally, the vertical rail includes two sliding rails on two sides and a transverse bridge for connecting the two sliding rails; the sliding rail is provided with a first sliding groove, and a second sliding groove is horizontally arranged on the first sliding groove in a penetrating mode.
Optionally, one side of the outer shell facing the vertical rail is provided with a pulley unit, the pulley unit comprises a plurality of first supports, a second support, a first pulley and a second pulley, two of the first supports are arranged on the side wall of the outer shell, the second support is horizontally connected to the two first supports in a rotating manner, the second pulley and the two first pulleys are arranged on the first supports, the first pulleys can slide in the first sliding grooves, and the second pulleys can slide in the second sliding grooves.
Optionally, the filter device comprises a filter screen.
Optionally, be equipped with annular guide rail groove along circumference on water installations, buoyancy bottom plate and the filter screen, be provided with annular chain of leading in the guide rail groove, it includes a plurality of chains and ball to lead the chain, the both ends of chain are connected with two adjacent balls respectively, the vertical pole of scraping that is equipped with on the ball, scrape the outer wall laminating that the pole can with water installations, shell body or filter screen.
Optionally, a plurality of square openings have been seted up on water installations's the shell, are provided with a plurality of wares of dialling in the water installations, the ware of dialling includes pivot and blade, the vertical rotation setting of pivot is in water installations, the blade sets up in the pivot along circumference, and the pivot is arranged at the bend department in water route and two relative blades respectively towards the both ends of water route bend, the blade can stretch out adjacent square opening and stir the scraping rod.
Optionally, the guide track groove is not completely cylindrical.
The working principle and the beneficial effects of the scheme are as follows:
1. in the scheme, the vertical rail is arranged, the outer shell and the buoyancy bottom plate are arranged on the vertical rail, the buoyancy bottom plate can float on the water surface, and the water inlet of the water inlet device is flush with the buoyancy bottom plate; therefore, when accumulated water exists in the foundation pit, the water inlet of the water inlet device is located on the uppermost layer of the accumulated water, the common silt on the uppermost layer of the accumulated water is minimum, and the accumulated water is not easy to block when flowing in from the water inlet because the foundation pit is generally free of garbage and the floating objects are also minimum. Simultaneously, when ponding degree of depth changed, the buoyancy bottom plate can drive whole shell body and rise or descend along with ponding volume change, guarantees that the water inlet is located surface of water department all the time.
2. The scheme is also provided with a guide chain, a rotating shaft, blades and other structures, when water flows exist in the water inlet device, the rotating shaft is arranged at the bent part of the water path, so that the water flows can push the blades to rotate; when the blade rotates, it can stir and scrape the pole and remove, just can scrape silt etc. on the filter screen when scraping the pole and removing.
3. The vertical rail in this scheme can also be done the stair and use, and when pumping device, filter equipment etc. broke down, maintenance personal can climb to the bottom through vertical rail and maintain.
4. Water installations's water route bending, debris such as silt, silt can be detained in the bend department in water route in this scheme, avoids silt to get into pumping device as far as possible.
5. Guide rail groove in this scheme is incomplete cylinder, leads including the ball in the chain, because ball and guide rail groove are the cambered surface, so the ball is more smooth and easy when removing, is difficult to appear phenomenons such as the card is dun.
