Description

Technical Field

[0001] This application relates to the field of cable tray technology, and in particular to a corrosion-resistant and fireproof cable tray. Background Technology

[0002] Corrosion-resistant and fireproof cable trays are a type of equipment used for cable laying and support. They are mainly used in environments that require corrosion and fire protection. These cable trays are usually made of a variety of materials to improve their corrosion resistance, fire resistance, and mechanical strength.

[0003] Because cable trays are used for loading and unloading cable equipment, there is a small probability of short circuits during transmission between cables. When the current carried by a cable exceeds its rated value, it will heat up. Furthermore, cables will age over time, resulting in reduced insulation. Improper cable laying or connection may also lead to localized fires. Utility Model Content

[0004] This application aims to address the technical problems of the low probability of short circuits during cable transmission, overheating when the current carried by the cable exceeds the rated value, aging of the cable after long-term use leading to reduced insulation, and the potential for localized fires due to improper cable laying or connection. The application provides a corrosion-resistant and fireproof cable tray.

[0005] This application employs the following technical means to solve the technical problem:

[0006] A corrosion-resistant and fireproof cable tray includes a lower groove, an upper cover, heat dissipation holes, a left locking groove, and a right locking groove;

[0007] The lower groove is designed with a concave structure, and the upper cover covers the lower groove to form an opening structure with a cavity, which is used for loading and unloading cables.

[0008] The heat dissipation holes are located on the left and right side walls of the lower groove and extend through the inside and outside.

[0009] The left and right locking slots are both located in the lower slot and are symmetrically arranged on the left and right sides of the lower slot relative to the center.

[0010] Furthermore, both the left and right locking slots are provided with barbs, which are located at the top middle of the left and right locking slots and expose a portion of the space.

[0011] Furthermore, both the left and right locking slots are provided with openings, and the openings of the left and right locking slots are respectively aligned with the heat dissipation holes of the lower slot.

[0012] Furthermore, the left locking groove and the right locking groove are arranged in an enclosing structure.

[0013] Furthermore, both the left and right locking grooves have dense mesh at their barbs.

[0014] Furthermore, the dense net is laid flat at the opening position of the top barb of the left lock groove and the right lock groove, and a bearing is provided at the bottom of one side of the dense net, so that the dense net rotates with the bearing on one side of the opening.

[0015] This application provides a corrosion-resistant and fireproof cable tray with the following advantages: It comprises a lower groove, a top cover, heat dissipation holes, a left locking groove, and a right locking groove; the lower groove is concave, and the top cover fits over the lower groove to form a cavity-shaped structure for loading and unloading cables; the heat dissipation holes are located on the left and right side walls of the lower groove and extend through the inside and outside; the left and right locking grooves are both located within the lower groove and are symmetrically arranged on the left and right sides of the lower groove relative to the center; both the left and right locking grooves have barbs located at the top center of the left and right locking grooves and partially exposed; both the left and right locking grooves have openings aligned with the heat dissipation holes adjacent to the lower groove; this design effectively addresses the technical problems of current cable transmission, such as the low probability of short circuits, overheating when the current exceeds the rated value, aging and reduced insulation due to prolonged use, and potential localized fires caused by improper cable laying or connection.

[0023] Reference Appendix Figure 1-2 This is a schematic diagram of the structure of the corrosion-resistant and fireproof cable tray in one embodiment of this application;

[0024] A corrosion-resistant and fireproof cable tray includes a lower groove 1, an upper cover 7, heat dissipation holes 6, a left locking groove 2 and a right locking groove 3;

[0025] The lower groove 1 is provided with a concave structure, and the upper cover 7 covers the lower groove 1 to form an opening structure with a cavity, which is used for loading and unloading cables;

[0026] The heat dissipation holes 6 are located on the left and right side walls of the lower groove 1 and extend through the inside and outside.

[0027] The left locking groove 2 and the right locking groove 3 are both located in the lower groove 1 and are arranged symmetrically with respect to the center on the left and right sides of the lower groove 1.

[0028] The left locking groove 2 and the right locking groove 3 are arranged in an enclosing structure.

[0029] In this embodiment, both the left locking groove 2 and the right locking groove 3 are provided with barbs 4, which are located at the top middle of the left locking groove 2 and the right locking groove 3 and expose a portion of the space.

[0030] Specifically, the cable is inserted into the lower groove 1. When inserting the cable into the lower groove 1, it can be rotated to either the left locking groove 2 or the right locking groove 3, or into the gap between the left locking groove 2 and the right locking groove 3. After the three parts of the cable, the left locking groove 2, the right locking groove 3 and the gap are inserted, the upper cover 7 is attached to the lower groove 1 to confine the three parts of the cable within the cable tray. In addition, the design of the barb 4 can prevent the sudden emergence of the cable's fire source and can also prevent the cable from being scattered. In the middle of the barb 4, the user can take out or insert the cable.

[0031] In this embodiment, both the left locking groove 2 and the right locking groove 3 are provided with openings, and the openings of the left locking groove 2 and the right locking groove 3 are respectively aligned with the heat dissipation holes 6 of the lower groove 1.

[0032] Specifically, when a fire occurs due to aging or a broken circuit in the cable, an opening is provided to prioritize fire evacuation of the cable. After the flames are evacuated through the opening, they can be led out through the heat dissipation hole 6 at the nearest ventilation location, which has a better fire resistance than ordinary cable trays.

[0033] In this embodiment, both the left locking groove 2 and the right locking groove 3 have a dense mesh 9 at their barbs 4.

[0034] In this embodiment, the dense net 9 is laid flat at the opening 5 position of the top barb 4 of the left locking groove 2 and the right locking groove 3, and a bearing 8 is provided at the bottom of one side of the dense net 9. The dense net 9 rotates on one side of the opening 5 along with the bearing 8.

[0035] Specifically, through the mesh 9, the user can rotate the mesh 9 away from the opening 5 in the barb 4 via the bearing 8 when installing the cable, and install the cable into the left locking groove 2 and the right locking groove 3. Then, the mesh 9 is moved from the distance of the opening 5 into the opening 5 via the bearing 8, which has the effect of limiting and preventing the fire source from leaking to other cable areas.

[0036] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
