Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a precipitation filtering device for tunnel engineering. Background Art

[0002] A hydraulic tunnel is a water tunnel dug in a mountain or underground. It can be used for irrigation, power generation, water supply, water discharge, water transfer, construction diversion and navigation. During tunnel excavation, a temporary water collection well is often set up 50 cm below the excavation surface to collect seepage water, which is then pumped out of the working surface through a drainage pipe connected to a pump.

[0003] However, the drainage pipes currently used only perform simple filtration before pumping out the water, but this method has obvious disadvantages: as the drainage operation proceeds, debris in the water tends to gradually settle on the surface of the filter pipe, forming a covering layer, which causes the filter holes to be blocked, seriously affecting the smoothness of the water flow, thereby reducing the drainage efficiency, and requiring workers to go down the well regularly to replace and clean them, which not only increases the workload, but may also delay the construction progress due to the problem of water accumulation, which has an adverse impact on the overall efficiency of the tunnel operation.

[0004] Therefore, it is urgent to make improvements to the above deficiencies in order to enhance the anti-clogging ability and ensure efficient and stable drainage operations. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the utility model provides a precipitation filtering device for tunnel engineering, which performs secondary filtration on sewage by arranging a water filter pipe and a filter sleeve, and drives the filter sleeve to rotate by a rotating ring and a driving assembly, thereby achieving good filtering effect, and solving the problem in the prior art that impurities are easily accumulated on the outside of the water filter pipe and cause drainage blockage.

[0006] A precipitation filtering device for tunnel engineering comprises a working box, a water filter pipe and a bottom plate, a check valve is arranged in the working box, the outlet end of the check valve is fixedly connected to a drainage pipe, the other end of the drainage pipe extends out of the working box and is connected to a water pump arranged on the ground, one end of the water filter pipe is fixedly connected to the base, the other end of the water filter pipe extends into the working box and is connected to the inlet end of the check valve, the upper and lower ends of the outer wall of the water filter pipe between the working box and the bottom plate are respectively rotatably connected to two rotating rings through bearings, the upper and lower ends of the two rotating rings are symmetrically arranged, a filter sleeve is detachably connected between the two rotating rings, and a driving component for driving the rotating ring to rotate is connected to the rotating ring.

[0007] A further technical solution is: the cross-section of the rotating ring is a T-shaped structure, and an annular limiting groove is opened at the opposite end of the outer side wall of the two rotating rings. The top and bottom ends of the filter sleeve are respectively embedded in the limiting groove and fixedly connected to the limiting groove by a first bolt.

[0008] A further technical solution is: the filter sleeve is assembled by a plurality of arc-shaped filter plates surrounding the limiting groove, and a plurality of filter holes are evenly opened on the filter plates.

[0009] A further technical solution is that a docking block and a docking groove are respectively arranged on the left and right sides of each filter plate.

[0010] A further technical solution is that an anti-slip pad is arranged on the side wall of the limiting groove.

[0011] A further technical solution is: a fixing rod is arranged between the working box and the bottom plate, a mounting groove is arranged in one side of the fixing rod close to the filter sleeve, and a cleaning brush for cleaning the surface of the filter sleeve is connected to the mounting groove through a second bolt.

[0017] During the drainage process, the motor is started to drive the transmission rod to rotate, and the second gear set on the outer wall of the transmission rod meshes with the first gear ring on the outer wall of the rotating ring, thereby driving the filter sleeve on the rotating ring to rotate, so that the debris adsorbed on the outer wall of the filter sleeve will fall off as the filter sleeve rotates, avoiding the accumulation of debris on the surface of the filter sleeve and causing blockage.
