Description

Technical Field

[0001] The utility model relates to the technical field of water accumulation removal, in particular to a device for removing water accumulation inside a tunnel. Background Art

[0002] Tunnels are engineering buildings buried in the ground, and are a form of human use of underground space. The structure of a tunnel consists of two parts: the main building and the ancillary equipment. The main building consists of the tunnel body and the tunnel door, and the ancillary equipment includes the car shelter, fire-fighting facilities, emergency communications and drainage facilities. Long tunnels also have special ventilation and lighting equipment. The original meaning is that there is water on the ground that has not been drained, or there is water on the ground, which is accumulated due to blockage or failure to drain.

[0003] When water accumulates in a tunnel due to heavy rainfall, it is necessary to clear the water in the tunnel in time. Generally, a pump is used to pump out the water inside the tunnel. Generally, a protective cover filter is installed at the water inlet end of the pump to filter out larger impurities in the accumulated water. However, most of the protective covers are spirally connected to the pumping pipe. If they are placed in the accumulated water for a long time, the sand and stones in the accumulated water will enter the spiral connection between the protective cover and the pumping pipe, making it inconvenient to disassemble and assemble the protective cover. Therefore, a device for removing water from the tunnel is proposed. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a device for removing water accumulation inside a tunnel, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a device for clearing water inside a tunnel, comprising: a carriage, a water pump, a water pumping pipe, a connecting cover, a connecting frame and a pull rod, a water pump is installed on one side of the interior of the carriage, a water pumping pipe is installed at the water inlet end of the water pump, a connecting cover is installed at the end of the water pumping pipe away from the water pump, connecting frames are symmetrically installed on the connecting cover, and pull rods are slidably connected to the interiors of the two connecting frames.

[0006] As a further technical solution of the utility model, a water storage frame is installed on the other side of the interior of the carriage, a water outlet pipe is installed on the front side of the water storage frame near the bottom, and a cover is spirally connected to one end of the water outlet pipe away from the water storage frame.

[0007] As a further technical solution of the utility model, the water outlet end of the water pump is fixedly connected to the water storage frame, a threaded rod is installed on the inner wall of one side of the carriage, a baffle is installed at one end of the threaded rod, and a baffle plate is threadedly connected to the threaded rod.

[0008] As a further technical solution of the utility model, a protective cover is provided at one end of the water pumping pipe, a filter screen is installed on the protective cover, filter holes of the same size are evenly arranged on the filter screen, and partitions are installed on both of the pull rods.

[0009] As a further technical solution of the utility model, springs are installed inside the two connecting frames, the two pull rods pass through the springs, the two partitions are located inside the connecting frames, and sockets compatible with the pull rods are provided on the left and right sides of the protective cover.

[0010] As a further technical solution of the utility model, the spring is located between the partition and the connecting frame, the front and back sides of the protective cover are symmetrically provided with protrusions, and the inner wall of the connecting cover is symmetrically provided with grooves adapted to the protrusions.

[0011] The utility model provides a device for removing water accumulation inside a tunnel, which has the following beneficial effects compared with the prior art:

[0012] 1. The tunnel internal water removal device designed in this invention is equipped with a connecting cover, a connecting frame and a pull rod. The protective cover is installed at one end of the water pumping pipe. The pull rod is pulled, and the pull rod slides inside the connecting frame and withdraws from the sockets on the left and right sides of the protective cover to separate the protective cover from the water pumping pipe. When installing the protective cover, the pull rod is inserted into the socket on the protective cover to fix the protective cover on the water pumping pipe to prevent sand and stones in the accumulated water from getting stuck in the connection between the protective cover and the water pumping pipe, making it easier to disassemble and assemble the protective cover and the water pumping pipe.

[0013] 2. The tunnel internal water removal device designed in this invention has baffles and springs. When the pull rod slides in the connecting frame, the baffle squeezes the spring, and the pull rod withdraws from the socket on the protective cover. When the pull rod is released, the elastic force of the spring resets the pull rod. When the protective cover is installed, the elastic force of the spring keeps the pull rod inserted into the socket on the protective cover at all times, thereby connecting the protective cover and the water extraction pipe.
