Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of railway traffic signals, and particularly relates to a waterproof and breathable method for a maintenance-free detector and a switch machine, which can reduce the daily maintenance work of the detector and the switch machine and improve the working reliability of the detector and the switch machine. Technical Background
[0002] The detectors and switch machines in the turnout conversion equipment are widely used in various complex outdoor environments at home and abroad. Rainwater and moisture can enter the machine from between the exposed moving parts of the detector and the switch machine and the main body housing, or enter the machine when the maintenance cover is opened. When performing daily maintenance, it is often found that there are phenomena such as water droplets, ice particles or frost condensation after opening the cover. This situation will corrode the internal components of the machine, resulting in jamming of the moving mechanism and poor electrical contact, posing serious quality hazards.
[0003] The on-site maintenance time is tight, and the number of equipment to be maintained is large. Manual maintenance is not sufficient to meet the on-site needs. Therefore, it is necessary to seek a method to reduce the internal humidity of the machine and ventilate and exchange air without opening the cover. Summary of the Invention
[0004] The purpose of the present invention is to provide a waterproof and breathable method for a maintenance-free detector and a switch machine, which can be applied to the situation with high internal humidity of the machine, ventilation requirements, high waterproof performance level, easy installation, strong applicability, and can reduce the internal humidity of the machine and ventilate and exchange air without opening the cover.
[0005] The purpose of the present invention is achieved as follows. It relates to a waterproof and breathable method for a maintenance-free detector and a switch machine, which is characterized in that it includes a breathable cover, a sealing gasket, a wire mesh, a sponge gasket, a sponge cover, and a fastener group; the bottom surface of the breathable cover and the sealing gasket are fixed as a first integral body, the wire mesh and the sponge gasket are fixed at the bottom of the sponge cover to form a second integral body, there are connection holes at the centers of the first integral body and the second integral body, and the fastener group is fastened through the connection holes at the centers of the first integral body and the second integral body.
[0006] The center of the breathable cover is a breathable cover installation hole, and a multi-sided folding breathable groove is formed around the breathable cover installation hole.
[0007] An outlet is formed on one side of the breathable cover of the multi-sided folding breathable groove.
[0008] In the multi-sided folding breathable groove, there are positioning posts on the edge of the breathable cover installation hole.
[0009] The multi-sided folding breathable groove is symmetrical to the connection line between the positioning post and the breathable cover installation hole. The two sides of the connection line are folded multiple times, and finally a groove-shaped structure that is merged at the bottom and open on the outside is formed.
[0010] The center of the sponge cover is a sponge cover mounting hole. The sponge cover mounting hole and the air permeable cover mounting hole are concentric mounting holes, and they are connected by a fastener group.
[0011] There are air holes around the sponge cover mounting hole.
[0012] The advantages of the present invention are as follows: Due to the adoption of an external gasket to block external rainwater from entering the machine and the ventilation grooves of the labyrinth long channel, it can effectively prevent rainwater from entering the machine. The positioning posts are used to achieve the positioning function of the air permeable cover installation, and the waterproof performance is not affected. It is easy to install and has strong applicability. It can reduce the humidity inside the machine and ventilate and exchange air by itself without opening the cover.

Detailed Embodiment
[0019] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined purpose, the following details the specific implementation manner, structural features and their effects of the present invention in conjunction with the accompanying drawings and embodiments.
[0020] As Figure 2 shown, the waterproof and breathable method of the maintenance-free detector and switch machine of the present invention includes: air permeable cover 2-1, gasket 2-2, wire mesh 2-3, sponge pad 2-4, sponge cover 2-5, fastener group 2-6; the bottom surface of the air permeable cover 2-1 and the gasket 2-2 are fixed as a first integral body, the wire mesh 2-3 and the sponge pad 2-4 are fixed at the bottom of the sponge cover 2-5 to form a second integral body, there are connection holes at the centers of the first integral body and the second integral body, and the fastener group 2-6 is fastened through the connection holes at the centers of the first integral body and the second integral body.
[0021] The described breathable cover 2-1 is a circular cover. The center of the breathable cover 2-1 is the breathable cover mounting hole 3-3. A polygonal folding breathable groove 3-1 is formed around the breathable cover mounting hole 3-3. An outlet is formed on one side of the breathable cover 2-1 of the polygonal folding breathable groove 3-1. Inside the polygonal folding breathable groove 3-1, there are positioning posts 3-2 on the edge of the breathable cover mounting hole 3-3.
[0022] The described polygonal folding breathable groove 3-1 is symmetrical to the connecting line of the positioning post 3-2 and the breathable cover mounting hole 3-3. The two sides of the connecting line are folded multiple times, and finally a groove-shaped structure that merges at the bottom and opens on the outside is formed.
[0023] The center of the described sponge cover 2-5 is the sponge cover mounting hole 4-1. The sponge cover mounting hole 4-1 and the breathable cover mounting hole 3-3 are concentric mounting holes, and they are connected by a fastener group 2-6. There are equally spaced breathable holes 4-2 around the sponge cover mounting hole 4-1.
[0024] As Figure 1 shown, during installation, the breathable cover 2-1 and the gasket 2-2 are installed on the outside of the cover of the airtight detector 1-1. The wire mesh 2-3, the sponge pad 2-4, and the sponge cover 2-5 are installed on the inside of the cover of the airtight detector 1-1. The fastener group 2-6 passes through all the breathable cover mounting holes 3-3 on the breathable device 1-2 and the cover of the airtight detector 1-1 for clamping at both ends, and finally fastening is achieved.
[0025] Figure 3 The positioning posts 3-2 on the breathable cover 2-1 ensure that the air vents face downwards and enable quick installation. The entire breathable device achieves double-layer sealing inside and outside the machine, effectively blocking rainwater from entering the machine while ensuring air circulation.
[0026] As Figure 3 shown, the breathable groove 3-1 on the breathable cover 2-1 is a labyrinthine long channel. Air enters through the breathable groove 3-1, passes through the holes on the gasket 2-2 and the cover of the airtight detector 1-1, the wire mesh 2-3, and the sponge pad 2-4, and finally enters the machine through the breathable holes 4-2 on the sponge cover 2-5, and flows out of the machine through another breathable device on the cover of the airtight detector 1-1 along the opposite path.
[0027] The breathable device 1-2 can prevent rainwater outside the machine from rebounding or seeping into the machine. In a humid environment, the wire mesh 2-3 and the sponge pad 2-4 further serve the purpose of dust and waterproof vapor. The breathable holes 4-2 on the sponge cover 2-5 are conducive to the air circulation inside the machine.
[0028] The above examples are only illustrative of the present invention and do not constitute a limitation on the protection scope of the present invention. Any design identical or similar to the present invention falls within the protection scope of the present invention.
