Evenly distributed filter screens 5 are fixedly connected through the top of the top plate 4, and a fan 18 is fixedly connected to the middle of the bottom of the top plate 4.

[0030] The cable tray mainly consists of a tray 1, a top plate 4, and a middle plate 6. Cables can be placed on the middle plate 6 inside the tray 1. The middle plate 6 is slidably connected to the sliding groove 11 on the fixing block 10 via limiting blocks 7 on both sides. This sliding connection allows the middle plate 6 to move flexibly between the fixing blocks 10, facilitating adjustment of the position of the middle plate 6 according to the number and size of the cables. A sliding rod 12 passes through the middle plate 6, and a lower locking block 8 fixedly connected to the top and bottom of its outer wall can restrict the position of the upper pressure plate 14. The upper pressure plate 14 can be positioned in the top of the outer wall of the sliding rod 12. The slide bar 12 slides between the middle and bottom. Spring 13 is sleeved on the top and bottom of the outer ring of the slide bar 12. In its natural state, spring 13 will lift the upper pressure plate 14 a certain distance. When it is necessary to fix the cable, the cable is placed on the middle plate 6, and then the upper pressure plate 14 is pressed down. The second rubber pad 15 at the bottom of the upper pressure plate 14 will contact the cable. At the same time, spring 13 is compressed, and the first rubber pad 9 at the top of the lower clamping block 8 will also contact the cable. The upper and lower rubber pads cooperate to clamp and fix the cable under the elastic force of spring 13. The setting of the rubber pads can also prevent the cable sheath from being damaged.

[0031] L-shaped blocks 16 are fixedly connected to both sides of the bottom of the top plate 4. Baffles 17 are fixedly connected to both sides of the top of the bridge frame 1, and the baffles 17 are slidably connected to the L-shaped blocks 16. Evenly distributed limiting blocks 7 are fixedly connected to both sides of the middle plate 6, and the limiting blocks 7 are slidably connected to the slide groove 11.

[0032] Each side of the cable tray 1 is fixedly connected to a second connecting plate 3 at one end and a first connecting plate 2 at the other end. The first connecting plate 2 and the second connecting plate 3 are slidably connected. This sliding connection method allows multiple cable trays 1 to be easily connected together, and the length of the cable tray can be extended according to actual installation needs to adapt to different laying environments and cable laying length requirements. A uniformly distributed filter screen 5 is fixedly connected through and to the top of the top plate 4. The filter screen 5 can prevent large foreign objects from entering the cable tray, providing initial protection. A fan 18 is fixedly connected to the bottom center of the top plate 4. During operation, the fan 18 allows air to circulate inside the cable tray. Heat is generated during cable operation, and the fan 18 can extract the hot air from inside the cable tray. At the same time, cool air from the outside can enter the cable tray through the gaps in the filter screen 5, forming an air circulation that dissipates heat and helps keep the cable within a suitable operating temperature range. The L-shaped blocks 16 on both sides of the bottom of the top plate 4 are slidably connected to the baffles 17 on both sides of the top of the cable tray 1. This connection method facilitates the installation and removal of the top plate 4 and keeps the top plate 4 in a relatively stable position on the cable tray 1, ensuring that the fan 18 and the filter screen 5 can function properly.

[0033] Working principle: This cable tray mainly consists of a tray 1, a top plate 4, and a middle plate 6. Cables can be placed on the middle plate 6 inside the tray 1.

This sliding connection allows the middle plate 6 to move flexibly between the fixing blocks 10, facilitating adjustment of the position of the middle plate 6 according to the number and size of the cables. A sliding rod 12 passes through the middle plate 6, and a lower locking block 8 fixedly connected to the top and bottom of its outer wall can restrict the position of the upper pressure plate 14. The upper pressure plate 14 can be positioned between the top and middle of the outer wall of the sliding rod 12. The bottom of the cable tray 1 slides, and spring 13 is fitted onto the top and bottom of the outer ring of the slide rod 12. In its natural state, spring 13 will cause the upper pressure plate 14 to rise a certain distance. When it is necessary to fix the cable, the cable is placed on the middle plate 6, and then the upper pressure plate 14 is pressed down. The second rubber pad 15 at the bottom of the upper pressure plate 14 will contact the cable, and at the same time, spring 13 is compressed. The first rubber pad 9 at the top of the lower clamping block 8 will also contact the cable. The upper and lower rubber pads cooperate, and the cable is clamped and fixed under the elastic force of spring 13. The rubber pads can also prevent the cable sheath from being damaged. Both ends of the cable tray 1 are fixed. A second connecting plate 3 is connected to the top plate 4, and a first connecting plate 2 is fixedly connected to the other side. The first connecting plate 2 and the second connecting plate 3 are slidably connected.

A uniformly distributed filter screen 5 is fixedly connected through and to the top of the top plate 4. The filter screen 5 can prevent large foreign objects from entering the cable tray, providing initial protection. A fan 18 is fixedly connected to the bottom center of the top plate 4. When the fan 18 is working, it can make the cable tray... The airflow inside the cable tray generates heat during cable operation. The fan 18 can extract the hot air from inside the cable tray, while cool air from the outside can enter the cable tray through the gaps in the filter 5, forming an air circulation that dissipates heat and helps keep the cables within a suitable operating temperature range. The L-shaped blocks 16 on both sides of the bottom of the top plate 4 are slidably connected to the baffles 17 on both sides of the top of the cable tray 1. This connection method facilitates the installation and removal of the top plate 4 and keeps the top plate 4 in a relatively stable position on the cable tray 1, ensuring that the fan 18 and the filter 5 can function properly.
