Technical Field

The invention belongs to the technical field of railway traffic signals, and particularly relates to a maintenance-free waterproof and breathable method for a security detector and a switch machine.

Technical Field

The secret detector and the point switch in the turnout switching equipment are widely applied to various complex outdoor environments at home and abroad. Rainwater and moisture can enter the machine from the space between the exposed moving parts of the switch machine and the main machine shell or enter the machine when the cover is opened during maintenance. During daily maintenance, the phenomenon of condensation of water drops, ice particles or frost is often found after the cover is opened. The situation can lead to corrosion of parts in the machine, and cause jamming of a moving mechanism and poor electrical contact, thereby generating serious quality hidden trouble.

The field maintenance time is short, the number of equipment to be maintained is large, and the field requirement cannot be met by manual maintenance. Therefore, a method for self-reducing humidity in the machine and ventilating without opening the cover is required.

Disclosure of Invention

The invention aims to provide a maintenance-free secret detector and a waterproof and breathable method of a point switch, which can be applied to a switch which has higher humidity in a machine, has breathable requirement, high waterproof performance level, convenient installation and strong applicability, and can automatically reduce the humidity in the machine and ventilate without opening a cover.

The invention aims to realize the purpose, and relates to a waterproof and breathable method of a maintenance-free secret detector and a switch machine, which is characterized in that: comprises a ventilating cover, a sealing gasket, a steel wire mesh, a spongy cushion, a sponge cover and a fastening piece group; ventilative lid bottom surface and sealed the pad fixing are first whole, and wire net and foam-rubber cushion fix the bottom at the sponge lid and form the second wholly, and there is the connecting hole at first whole and the whole center of second, and fastener group fastens through first whole and the whole central connecting hole of second.

The center of the breathable cover is a breathable cover mounting hole, and a polygonal folding breathable groove is formed in the periphery of the breathable cover mounting hole.

An outlet is formed on one side of the ventilation cover of the multi-edge folding ventilation groove.

In the multilateral folding ventilative inslot, there is the reference column ventilative lid mounting hole edge.

The multi-side folding ventilation grooves are symmetrical to connecting lines of the positioning columns and the ventilation cover mounting holes, and two sides of the connecting lines are folded for multiple times to finally form a groove-shaped structure which is combined at the bottom and is opened at the outer side.

The center of the sponge cover is provided with a sponge cover mounting hole, and the sponge cover mounting hole and the ventilation cover mounting hole are concentric mounting holes and are connected through a fastener group.

Air holes are arranged around the sponge cover mounting hole.

The invention has the advantages that: because the external sealing gasket is adopted to prevent external rainwater from entering the machine and the ventilation grooves of the labyrinth long channels, the external sealing gasket can effectively prevent rainwater from entering the machine. Adopt the reference column to realize ventilative lid installation locate function to can not influence waterproof performance. The novel air conditioner is convenient to install and high in applicability, and automatically reduces the humidity in the air conditioner and ventilates without opening the cover.
