[0002] With the development of intelligent buildings, a single building often contains AC high-voltage systems, low-voltage systems, DC high-voltage systems, and various automation systems, such as building automation systems, office automation systems, and communication automation systems. Therefore, it is necessary to lay various types of cables simultaneously, including AC high-voltage cables, DC high-voltage cables, and low-voltage cables such as communication cables and control cables. These different types of cables need to be laid separately during the wiring design, hence the widespread use of cable trays for cable routing.

[0003] According to Chinese Patent Publication No. CN 212935444 U, a cable box body is disclosed. The cable box body includes a bottom, a first side, and a second side. The first and second side are arranged parallel to each other on opposite sides of the bottom, forming a U-shaped structure. A first reinforcing structure and a first heat dissipation structure are provided on the first side; a second reinforcing structure and a second heat dissipation structure are provided on the second side. This utility model embodiment of the cable tray, by providing a first reinforcing structure and a first heat dissipation structure, and a second reinforcing structure and a second heat dissipation structure on the first and second side of the cable box respectively, enhances the structural strength of the cable tray and provides better heat dissipation.

[0004] However, the aforementioned device cannot dissipate heat, causing the internal temperature of the cable to rise, which can lead to serious safety problems such as short circuits or fires. Utility Model Content

[0005] The purpose of this invention is to provide a protective cable tray to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a protective cable tray, including a fixing cover, a support rod fixedly connected to the top center of the fixing cover, and a side fixing plate fixedly connected to the right side of the support rod;

A support plate is fixedly connected to the right side of the retaining plate. A sliding groove is provided on the top of the support plate. A slider is movably connected to the surface of the sliding groove. A compression spring is fixedly connected to the right side of the slider. A fixing block is fixedly connected to the top right side of the support plate. One end of the compression spring is fixedly connected to the left side of the fixing block. Threaded holes are provided on both sides of the top of the fixing cover. Bolts are threaded into the internal threads of the threaded holes.

[0008] Preferably, a cable tray body is provided on the top of the support plate, and a top cover is movably connected to the top of the cable tray body.

[0009] Preferably, a base plate is movably connected to the bottom of the cable tray body, and a cooling air device is fixedly connected to the top interior of the cable tray body.

[0010] Preferably, the cooling device has a fan shaft internally connected to it, and fan blades are fixedly connected to the surface of the fan shaft, with multiple fan blades provided.

[0011] Preferably, the surface of the base plate is provided with heat dissipation holes, and multiple heat dissipation holes are provided.

[0012] Preferably, nuts are fixedly connected to both sides of the interior of the base plate, and multiple nuts are provided.

[0013] Preferably, hexagonal head bolts are movably connected to the outer sides of the top cover, and the number of nuts is equal to the number of hexagonal head bolts.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] Firstly, this utility model features a side fixing plate fixedly connected to the right side of a support rod, an installation box on the right side of the fixing plate, a support plate fixedly connected to the right side of the clamping plate, a sliding groove on the top of the support plate, a slider movably connected to the surface of the sliding groove, a compression spring fixedly connected to the right side of the slider, and a fixing block fixedly connected to the top right side of the support plate. One end of the compression spring is fixedly connected to the left side of the fixing block. The cable tray can be steadily lifted by the sliding groove on the support plate. The size can be adjusted by the left and right movement of the slider in the sliding groove and the compression spring, thus pressing down the cable tray. This design is suitable for cable trays of different sizes, making the cable tray more stable when installed on the support plate. It also ensures that the cable tray remains stable in various environments, preventing cable damage or safety accidents caused by shaking or displacement, and improving the efficiency and reliability of the electrical system.

[0016] Secondly, this utility model features a cooling device fixedly connected to the top of the cable tray body. This cooling device can reduce the operating temperature of the cables or related equipment, preventing damage or performance degradation caused by overheating, effectively improving service life, and avoiding accelerated aging of the insulation material and reduced insulation performance when the cable is running in a high-temperature environment. Furthermore, the surface of the base plate has heat dissipation holes, which mainly promote air circulation inside the cable tray. During power transmission, the cable will heat up due to the current passing through it. If the heat cannot be dissipated in time, it will cause the internal temperature of the cable tray to rise, posing a potential threat to the insulation layer and overall performance of the cable. The heat dissipation holes can effectively dissipate the heat, thereby effectively reducing the internal temperature of the cable tray and ensuring the safe and stable operation of the cable tray and the cables on it.
