The controller control circuit can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0035] Working principle:

[0036] Before actually using the automatic temperature rise detection and alarm device for cable trays, first open a through hole on the surface of the control box 10 to ensure that the wires connected to the external alarm and the temperature sensing cable 9 can be inserted into the control box 10. The gap between the through hole and the wire is sealed with high-temperature resistant glue. The wires connected to the external alarm are electrically connected to the controller. When the temperature sensing cable 9 needs to be installed, the operator slides the multiple sets of socket plates 7 horizontally by hand. When the multiple sets of socket plates 7 are in contact with each other, the operator can move one end of the temperature sensing cable 9 by hand to pass through the multiple sets of through holes 8 at one time. Then, the sleeve 13 is fitted onto one end of the temperature sensing cable 9, and the two sets of T-shaped rods 14 are released. The two sets of telescopic springs 16 can be pushed by their own elastic force. Move the two sets of arc-shaped clamps 15 to stably clamp one end of the temperature-sensing cable 9. Then move the multiple sets of socket plates 7. When the multiple sets of socket plates 7 are moved to the appropriate positions, the threaded through holes 19 and the threads of the fastening bolts 20 engage. The operator, wearing heat-resistant gloves, rotates the fastening bolts 20 clockwise. The fastening bolts 20 allow the brake plate 18 to move down. When the brake plate 18 contacts the upper part of the multiple sets of socket plates 7, the position of the multiple sets of socket plates 7 is fixed. At this point, the temperature-sensing cable 9 is installed. When the cable inside the box 1 generates high temperature, the temperature-sensing cable 9 can send a signal to the controller. The controller activates the external alarm. The operator can hear the sound emitted by the external alarm. The sound allows for timely response. The second ball bearing 22 prevents the brake plate 18 from obstructing the rotation of the fastening bolt 20. Multiple sets of first ball bearings 12 prevent multiple sets of socket plates 7 from scratching the temperature sensing cable 9. The installation block 5, crossbar 6, and socket plate 7 facilitate the installation of the temperature sensing cable 9, making the installation of the temperature sensing cable 9 of the automatic temperature rise detection alarm device for cable trays more convenient. At the same time, when the box 1 is used in a coal mine, a large amount of coal dust will enter the box 1. Due to the presence of multiple sets of hollow grooves 2, some coal dust will be moved out of the box 1 through the multiple sets of hollow grooves 2. When it is necessary to clean the coal dust remaining inside the box 1, the operator wears heat-resistant gloves and moves the two sets of limit plates 24 back and forth. The limiting plate 24 can move the two sets of scrapers 3 inside the box 1 through four sets of connecting rods 23. During this process, the two sets of scrapers 3 can push out the residual coal powder inside the box 1 through multiple sets of hollow grooves 2. After use, the two sets of limiting plates 24 are reset, and then the two sets of connecting screws 25 and four sets of connecting nuts 26 are engaged by the threads. The operator can rotate the four sets of connecting nuts 26 clockwise and counterclockwise by hand. When the four sets of connecting nuts 26 contact the two sets of limiting plates 24, the two sets of scrapers 3 are stably fixed and ready for the next use. The hollow grooves 2 and scrapers 3 provide a cleaning structure, which can facilitate the cleaning of coal powder inside the cable tray box and improve the practicality of the automatic temperature rise detection and alarm device for the cable tray box.
