Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a cable tray structure. Background Technology

[0002] In modern infrastructure and industrial production systems, cables play a crucial role in power transmission and signal transmission. Cable trays, as important facilities for supporting and protecting cables, have a rich and complex history of development and application.

[0003] Existing technology publication CN212518250U discloses a cable tray structure, relating to the field of cable tray technology, which facilitates cable maintenance by workers. It includes a frame and a cover plate. The frame includes a rectangular base plate and vertical plates disposed on both sides of the base plate, forming a cavity for cable placement between the base plate and the two vertical plates. The frame contains a separating assembly for separating cables. The separating assembly includes multiple separating plates slidably connected to the base plate, and the separating plates are movable along the width direction of the base plate. Separating grooves for cable placement are formed between adjacent separating plates. This application can separate various types of cables, thereby reducing the operational difficulty during cable maintenance.

[0004] However, existing cable tray structures typically use connecting parts and bolts for connection and fixation during installation. This installation method leads to cumbersome operation steps and high installation difficulty. Furthermore, because a large number of cables need to be installed in the cable tray, and the cable tray cannot automatically extinguish the fire in the early stages of a fire to prevent the fire from spreading, the cable tray has poor safety. Therefore, we propose a new cable tray structure. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This utility model provides a cable tray structure, which has the following advantages:

[0017] (1) This type of cable tray structure, through the setting of locking slots, connecting rods and latches, allows the workers to insert the connecting rod of one cable tray body into one side of the other cable tray body when installing the cable tray. At this time, the connecting rod will retract inward, and the latch on the connecting rod will be inserted into the locking slot. At this time, the two cable trays can be connected. When disassembly is required, the workers only need to press the latch, at which time the latch will disengage from the locking slot, and then pull out the connecting rod to complete the disassembly. This method simplifies the operation steps of installing and disassembling cable trays, thus making it convenient for workers to install and disassemble cable trays.

[0018] (2) This type of cable tray structure, through the installation of fire extinguishing tank, exhaust pipe, solenoid valve and fire detector, when the cable tray and cable are installed and the cable catches fire during the power supply process, the fire detector will detect it. At this time, the solenoid valve will be activated, and the carbon dioxide inside the fire extinguishing tank will enter the gas supply pipe through the exhaust pipe. At this time, the jet head will spray carbon dioxide to the fire position, thereby extinguishing the fire source. This allows the cable tray to automatically extinguish the fire in the early stage and prevent the fire from spreading, thus improving the safety of the cable tray. Attached Figure Description

[0026] Furthermore, a jet nozzle 14 is installed on the outside of the gas supply pipe 13. Multiple jet nozzles 14 are provided, and the multiple jet nozzles 14 are the same size. Carbon dioxide can be sprayed out evenly through the jet nozzles 14, thereby better extinguishing the fire source.

[0027] Furthermore, the top of the mounting bracket 2 is integrally connected to the mounting plate 3, and the top of the mounting plate 3 has a mounting opening 4. During installation, the mounting plate 3 is positioned in the installation position, and then the bolts are inserted into the mounting opening 4 for tightening.

[0028] Furthermore, the fire detector 15 has a detection port 17 on its outer side. Multiple detection ports 17 are arranged at equal intervals. When the cable catches fire, the smoke can quickly enter the fire detector 15 through the detection port 17.

[0029] Furthermore, the cable tray body 1 is made of metal material, and the outer surface of the cable tray body 1 is smooth. The cable tray body 1 made of metal material is more robust and durable.

[0030] Furthermore, there are two locking ports 5, which are symmetrically arranged, and the latch 7 can be engaged through the locking ports 5.

[0031] Furthermore, the cable tray body 1 and the connecting rod 6 are an integral structure. The width of the connecting rod 6 is adapted to the inner width of the cable tray body 1. When the connecting rod 6 of one cable tray body 1 is inserted into the side of the other cable tray body 1, the connecting rod 6 will retract inward, and the latch 7 on the connecting rod 6 will be inserted into the locking hole 5. At this time, the two cable trays can be connected.

[0032] Working Principle: After installation, the installation, fixation, and safety protection of this utility model are checked first. When installing the cable tray, the worker inserts the connecting rod 6 of one cable tray body 1 into one side of the other cable tray body 1. At this time, the connecting rod 6 will retract inward, and the locking buckle 7 on the connecting rod 6 will be inserted into the locking port 5. At this time, the two cable trays can be connected. When the cable tray and cable are installed, and the cable catches fire during the power supply process, the fire detector 15 will detect it. At this time, the solenoid valve 12 will be activated, and the carbon dioxide inside the fire extinguisher 10 will enter the gas supply pipe 13 through the exhaust pipe 11. At this time, the jet nozzle 14 will spray carbon dioxide to the fire position, thereby extinguishing the fire source. This allows the cable tray to automatically extinguish the fire in the early stage and prevent the fire from spreading. When disassembly is required, the worker only needs to press the locking buckle 7, at which time the locking buckle 7 will disengage from the locking port 5, and then the connecting rod 6 can be pulled out to complete the disassembly.
