DETAILED DESCRIPTION

[0023] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides a safe and stable cable tray through improvement. The technical solution of the utility model is:

[0025] like Figures 1 to 4 As shown, a safe and stable cable bridge comprises a bridge body 1, a cover plate 2 and a mounting rod 3. The bridge body 1 is a hollow rectangular structure. The cover plate 2 is movably mounted on the top of the bridge body 1. There are multiple mounting rods 3, and multiple mounting rods 3 are fixedly mounted on the external ceiling. The bridge body 1 is movably mounted between multiple mounting rods 3. The bottom of the bridge body 1 is provided with multiple heat dissipation ports 4. The heat dissipation ports 4 are rectangular grooves. A mounting shaft 5 is movably mounted on one side of the heat dissipation port 4. The mounting shaft 5 is a cylindrical structure, and the mounting shaft 5 is a torsion spring shaft. A sealing plate 6 is fixedly sleeved on the mounting shaft 5. The sealing plate 6 is a rectangular plate adapted to the heat dissipation port 4. Baffles 15 are fixedly mounted on both sides of the sealing plate 6. An electric telescopic rod 7 is fixedly installed inside the frame body 1, and a push rod 8 is fixedly installed on the output end of the electric telescopic rod 7. The push rod 8 is a rod with a rectangular structure, and one end of the push rod 8 is in contact with the top of the sealing plate 6. A temperature detector and a controller are also provided inside the bridge body 1. The cable is installed inside the bridge body 1. When the internal temperature of the bridge body 1 is high, the temperature detector will detect it, and then the electric telescopic rod 7 can be started by the controller. The electric telescopic rod 7 drives the push rod 8 to move downward, and the push rod 8 moves downward to squeeze the sealing plate 6. After the sealing plate 6 is squeezed, it will flip with the installation axis 5 as the base point, so that the heat dissipation port 4 can be opened, so that the inside of the bridge body 1 can be cooled.

[0026] A first mounting groove 9 is provided inside the bridge body 1 at a position corresponding to the heat dissipation port 4. The first mounting groove 9 is a groove of a rectangular structure. The first mounting groove 9 is communicated with the interior of the heat dissipation port 4. A reel 10 is movably installed inside the first mounting groove 9 through a torsion spring. The reel 10 is a cylindrical structure. A dustproof net 11 is wound on the reel 10. The other end of the dustproof net 11 is fixedly connected to the sealing plate 6. When the sealing plate 6 is flipped over, the dustproof net 11 will be pulled down from the reel 10, thereby blocking the heat dissipation port 4. At this time, the air entering the interior of the bridge body 1 through the heat dissipation port 4 will be filtered to prevent dust from entering the interior of the bridge body 1.

[0027] When heat is discharged next time, the cleaning brush 13 will be moved out again under the action of the return spring 14, thereby cleaning the dustproof net 11 again, achieving the effect of automatically cleaning the dustproof net 11 after use.

[0028] The mounting rod 3 is a hollow rectangular structure. An opening 16 is provided on the mounting rod 3 at a position corresponding to the bridge body 1. A support block 17 is movably installed inside the opening 16. The support block 17 is a trapezoidal structure block. The downward side wall of the support block 17 is an inclined surface. A pull rod 18 is movably installed at a position corresponding to the support block 17 on the mounting rod 3. The pull rod 18 is a cylindrical rod. The pull rod 18 passes through the inner and outer side walls of the mounting rod 3. A connecting block 19 is fixedly installed between the pull rod 18 and the support block 17. The pull rod 18 is sleeved with a support spring located inside the mounting rod 3. Spring 20. When the height of the bridge body 1 needs to be adjusted, the bridge body 1 can be directly pushed upward. The upward movement of the bridge body 1 can squeeze the inclined surface of the support block 17, so that the support block 17 can be moved to the inside of the mounting rod 3, and at the same time squeeze the support spring 20. When the bridge body 1 moves to the appropriate position, the support block 17 loses the squeezing force and will be reset under the action of the support spring 20. At this time, the bridge body 1 can be supported by the support block 17, thereby achieving the effect of arbitrarily adjusting the installation height of the bridge body 1.

[0029] The specific working methods are:

[0030] When the internal temperature of the bridge body 1 is high, the temperature detector will detect it, and then the electric telescopic rod 7 can be started through the controller, and the electric telescopic rod 7 drives the push rod 8 to move downward. The downward movement of the push rod 8 will squeeze the sealing plate 6. After being squeezed, the sealing plate 6 will flip with the mounting shaft 5 as the base point, so that the heat dissipation port 4 can be opened, so that the interior of the bridge body 1 can be dissipated. At the same time, the dustproof net 11 will also be pulled down from the winding shaft 10, so as to block the heat dissipation port 4. At this time, the air entering the interior of the bridge body 1 through the heat dissipation port 4 will be filtered to prevent dust from entering the interior of the bridge body 1;

[0031] When the heat dissipation is completed, the electric telescopic rod 7 drives the push rod 8 to reset, and the sealing plate 6 will also reset under the action of the mounting shaft 5. When the sealing plate 6 flips upward, the winding shaft 10 will rewind the dustproof net 11. At this time, the cleaning brush 13 can clean the surface of the dustproof net 11 and clean the dust remaining on the dustproof net 11. Then the cleaning brush 13 will be reset under the pressure of the sealing plate 6 and squeeze the reset spring 14. When the heat is dissipated next time, the cleaning brush 13 will be moved out under the action of the reset spring 14, thereby cleaning the dustproof net 11 again, achieving the effect of automatically cleaning the dustproof net 11 after use.
