Description

Technical Field

[0001] The present invention relates to the technical field of cable trays, and in particular to self-cleaning and dust-proof cable trays. Background Art

[0002] Cable trays can be used to support cables. Due to their special structure, cable trays can act as a skeleton for cables, effectively attaching and supporting cables to buildings. At the same time, they can also independently support cables to pass through various tunnels or caves. Cable trays can isolate cables from the outside world and wrap and protect cables.

[0003] After searching, the disclosure (announcement) number CN220358741U discloses a plug-in dust-proof cable tray, including a tray shell, a shell cover is provided on the top of the tray shell, and ventilation and heat dissipation holes are equidistantly provided on both side walls of the tray shell... This application can better prevent dust in the external environment from entering the tray shell by arranging a frame and a dust-proof filter at the ventilation and heat dissipation holes, so it can have a better dust-proof effect. By arranging positioning columns, positioning holes, fixing blocks, sockets, U-shaped plates, plug-in rods, trapezoidal shift blocks, first springs, trapezoidal stops, pull blocks and second springs, the frame can be disassembled and assembled more conveniently. When the mesh of the dust filter is clogged and the ventilation and heat dissipation effect is affected, the frame together with the dust filter can be removed from the tray shell more conveniently, so it is convenient to clean the dust filter. This application does not have a device for automatically cleaning the dust filter. When cleaning the dust filter, the dust filter needs to be disassembled and cleaned. After the dust filter is disassembled, it needs to be installed again. The operation is cumbersome, and manual cleaning after disassembly increases the workload of the personnel, which is time-consuming and labor-intensive.

[0004] In summary, how to automatically clean the dust filter without removing it and reduce the workload of workers is a technical problem that needs to be solved urgently. To this end, we propose a self-cleaning dustproof cable tray. Utility Model Content

[0008] According to the technical solution provided in the embodiment of the present application, the transmission assembly includes a rectangular plate, a second transmission belt and a first transmission belt. Two rectangular plates are symmetrically fixedly connected on the front and rear sides of the bottom end face of the bridge body. A rotating rod is rotatably connected between the two adjacent rectangular plates. The rotating rod and the screw rod are connected by the second transmission belt, and the two rotating rods are connected by the first transmission belt.

[0009] According to the technical solution provided in the embodiment of the present application, threaded holes are symmetrically provided on the horizontal plate, and fixing bolts are inserted into the internal threads of the threaded holes. Limiting grooves are symmetrically provided on the top of the frame, and the lower ends of the fixing bolts extend to the inside of the limiting grooves.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The control motor works in conjunction with the transmission assembly to drive the two screws to rotate in the same direction. The rotation of the screw drives the sliding block to move inside the sliding groove. The movement of the sliding block drives the fixed plate and the brush to move. The brush can brush off the dust on the surface of the dust filter, thereby ensuring the heat dissipation effect. In summary, compared with the existing technology, the operation of disassembling the dust filter is eliminated, and the automatic cleaning of the dust filter is realized, saving time and effort.
