Description

Technical Field

[0001] This utility model belongs to the field of power tunnel technology, specifically a power tunnel ventilation device. Background Technology

[0002] The electrical tunnel contains a large number of cables, which generate heat during use. Therefore, in addition to considering the cable laying requirements, the design of the electrical tunnel also requires the installation of ventilation devices to facilitate rapid air exchange and heat dissipation inside the tunnel, in order to ensure the safe operation of the cables inside.

[0003] In the current technology, when the ventilation device exhausts the hot air from the power tunnel to the outside, it also discharges dust particles from inside the tunnel into the atmosphere, causing pollution to the outside environment. Existing methods of installing filter screens at the ventilation openings of power tunnels to filter airborne particles are also used. However, although the filter screens and other filtering devices have a good filtration effect, they are also easy to clog. Once the mesh holes are blocked, they need to be replaced or the dust particles on the mesh need to be shaken off and cleared, which increases manpower and labor costs. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the existing technology and provide a ventilation device for power tunnels. This invention utilizes a movable filter screen at the air outlet. Once the filter screen is covered in dust, it can be moved to one side, and the dust can be dislodged by tapping it with a rod. This allows for repeated use, reducing replacement frequency and thus reducing manpower and labor costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a power tunnel ventilation device, comprising a ventilation hood located on the air outlet of the power tunnel, with ventilation openings on the front and rear sides of the ventilation hood, a fan installed inside the ventilation openings, and a filtration mechanism and a dust removal structure installed inside the ventilation hood; the filtration mechanism includes a first roller, a second roller, and a filter cloth, with the first roller and the second roller respectively located on the left and right sides of the air outlet, the filter cloth being wound around the first roller and the second roller, and the second roller being driven to rotate by a driver; the filter cloth located on the lower side is close to the air outlet, and the dust removal structure includes a tapping rod for tapping the filter cloth.

[0006] Preferably, the dust removal structure further includes a turntable disposed at one end of the second roller, the turntable having a plurality of protrusions on its outer periphery; one end of the knocking rod rests on the filter mesh, the other end abuts between the protrusions of the turntable, the middle part of the knocking rod is rotatably connected to the ventilation hood, and the knocking rod has a thrust spring on the side near the filter mesh.

[0007] Preferably, the ventilation hood has an inverted U-shaped baffle on the air outlet, and the ventilation outlet is located between the filter mesh on the upper and lower sides and within the area surrounded by the inverted U-shaped baffle.

[0008] Preferably, the vertical plate of the inverted U-shaped baffle has a through-slit, through which the filter mesh on the lower side passes.

[0009] Preferably, the air outlet is provided with limiting grooves on both sides, and the filter mesh is provided with rubber strips on both sides that cooperate with the limiting grooves.

[0010] Preferably, a storage box is provided below the filter mesh, and the storage box is arranged vertically and vertically corresponding to the knocking rod.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] (1) The second roller is driven to rotate by the driver, and the filter cloth is moved on the air outlet with the cooperation of the first roller. After the filter cloth at the air outlet is full of dust, it can be turned to one side. The dust can be removed by tapping the filter cloth with the knocking rod of the dust removal structure, so that it can be recycled, reducing the replacement frequency and reducing manpower and labor costs.

[0013] (2) The rotating protrusion of the turntable causes one end of the knocking rod to move up and down repeatedly, so that the other end of the knocking rod can continuously hit the filter cloth to remove dust. The structure is simple and practical.

[0014] (3) Use an inverted U-shaped baffle to separate the air outlet and the ventilation opening to facilitate the exhaust of gas.

[0015] (4) Rubber strips that fit into the limiting grooves are provided on both sides of the filter cloth to facilitate the movement of the filter cloth.

[0016] (5) A storage box is provided below the filter screen. The dust that is knocked off falls into the storage box and is collected and processed. Attached Figure Description
