[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 , an explosion-proof motor overload detection device based on temperature monitoring, comprising a motor body 1, support frames 2 are provided on both sides of the bottom end of the motor body 1, monitors 4 are provided on both sides of the top end of the motor body 1, a connecting plate 5 is provided between the monitors 4, a controller 6 is provided on the top end of the connecting plate 5, an intelligent timer 7 is provided on the controller 6, an alarm 8 is provided on the side of the top end of the connecting plate 5, a monitoring probe 9 is provided in the monitor 4, one end of the monitoring probe 9 is against the motor body 1, a card slot 10 is provided on both sides of the monitor 4, a mounting bracket 3 is provided on both sides of the motor body 1, and the mounting bracket 3 is provided on both sides of the motor body 1. A fixed rod 11 is provided on the inner side, and a spring 12 is provided on the fixed rod 11. A movable plate 13 is provided at one end of the fixed rod 11, and the movable plate 13 is slidably connected to the fixed rod 11. A side plate 14 is provided on one side of the movable plate 13, and a card block 15 is provided on one side of the side plate 14. One end of the card block 15 is against the inside of the card slot 10. A pull plate 16 is provided between the movable plates 13, and a handle 17 is provided in the middle of one side of the pull plate 16. The intelligent timer 7, alarm 8, and monitor 4 are all electrically connected to the controller 6. There are multiple monitoring probes 9, and they are evenly arranged inside the monitor 4.

[0025] In actual use of the above structure, the monitor 4 is installed on the motor body 1. During installation, the monitor 4 is covered on the motor body 1 and the monitor 4 is limited and fixed by the block 15 so that it can be firmly fixed on the motor body 1. When the motor body 1 is running, the monitoring probe 9 in the monitor 4 can monitor the motor body 1 and use the intelligent timer 7 to time. When it is detected that the motor body 1 is in a high temperature state for a long time, the controller 6 transmits a signal and turns on the alarm 8. The alarm 8 sounds an alarm, thereby quickly reminding people to avoid the motor body 1 being damaged by being in a high temperature device for a long time, and effectively preventing the motor body 1 from being overloaded. When the monitor 4 needs to be disassembled, it is only necessary to manually pull the handle 17. The handle 17 drives the movable plate 13 through the pull rod. The movable plate 13 squeezes the spring 12 on the fixed rod 11. At the same time, the movable plate 13 will drive the side plate 14 and the block 15, so that the block 15 exits the slot 10. At this time, the monitor 4 loses its limit and the monitor 4 can be easily removed from the motor body 1.

[0026] In this embodiment, the handle 17 is rotatably connected to the pull plate 16, and the handle 17 is provided with anti-slip grooves. When the monitor 4 is disassembled, the handle 17 is pulled and then rotated so that both sides of the handle 17 are against the mounting bracket 3 to prevent the spring 12 from rebounding, thereby facilitating the disassembly of the monitor 4.

[0027] In this embodiment, a plurality of fixing rods 11 and springs 12 are provided and evenly arranged in the mounting frame 3 , thereby improving the stability of the movable plate 13 when sliding.

[0028] In this embodiment, the support frame 2 is detachably connected to the motor body 1 , and a mounting hole is provided on the support frame 2 to facilitate installation of the support frame 2 .

[0029] Furthermore, the present invention is improved in that the inner wall of the monitor 4 is attached to the outer wall of the motor body 1 .

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
