Under the drive of the motor 5, the driving wheel 6 drives the driven wheel 7 to rotate, the driven wheel 7 drives the wheel shaft 11 to rotate, and the wheel shaft 11 drives the pulley 4 to rotate, so that the moving seat 3 moves along the direction of the track 1.

[0035] In this embodiment, preferably, the moving mechanism includes a gear 12 provided outside the pulley 4. The gear 12 is coaxially connected to the wheel shaft 11, and a rack 13 meshing with the gear 12 is provided outside the track 1.

[0036] The moving mechanism includes a gear 12 and a rack 13. The gear 12 is located outside the pulley 4 and is coaxially connected to the wheel shaft 11. It can be that the gear 12 is sleeved at the end of the wheel shaft 11. The rack 13 is located outside the track 1 and is arranged to match the gear 12. The gear 12 and the rack 13 are meshed with each other. Under the drive of the motor 5, the driving wheel 6 drives the driven wheel 7 to rotate, the driven wheel 7 drives the wheel shaft 11 to rotate, and the wheel shaft 11 drives the pulley 4 to rotate, so that the moving seat 3 moves along the direction of the track 1. At the same time, the wheel shaft 11 drives the gear 12 to rotate. When the moving seat 3 moves along the direction of the track 1, the gear 12 and the rack 13 remain in meshed connection, making the movement more stable, and when the moving seat 3 is in a stationary state, it plays a certain limiting role.

[0037] In this embodiment, preferably, the moving mechanism includes a pin hole 14 provided inside the track 1 and a positioning pin 15 provided outside the moving seat 3. The positioning pin 15 can be telescopically inserted into the pin hole 14.

[0038] The moving mechanism includes a pin hole 14 and a positioning pin 15. The pin hole 14 is opened on the inner side of the track 1, and several pin holes 14 may be arranged at intervals along the direction of the track 1. The positioning pin 15 is telescopically arranged, and a spring pin structure may be adopted. The positioning pin 15 and the pin hole 14 are matched with each other and are movably inserted. The positioning pin 15 is installed on the outer side of the moving seat 3 and may be aligned with the central axis of the moving seat 3. When the moving seat 3 moves along the direction of the track 1, the positioning pin 15 is retracted due to the extrusion on the inner side of the track 1. When it reaches the specified position, the moving seat 3 stops moving, and the positioning pin 15 is aligned with the pin hole 14 corresponding to this position. The positioning pin 15 is reset and extended to be inserted into the pin hole 14, so as to play a limiting role and improve the accuracy of position adjustment.

[0039] In this embodiment, preferably, the moving mechanism includes a pin rail 16 slidably connected to the positioning pin 15. The pin rail 16 is arranged along the inner side of the track 1, and the pin holes 14 are distributed at intervals in the pin rail 16.

[0040] The moving mechanism includes a pin rail 16. The pin rail 16 is located on the inner side of the track 1 and is arranged along the direction of the track 1. Several pin holes 14 are distributed at intervals in the pin rail 16. In the actual use scenario, the positions of the pin holes 14 can be preset according to the combustible area to ensure that the fire extinguisher 2 can move to the most suitable fire extinguishing position. The positioning pin 15 may be located in the pin rail 16, and the inner shape of the pin rail 16 matches the end shape of the positioning pin 15. The inner side of the pin rail 16 is smooth to reduce the friction between the positioning pin 15 and the pin rail 16 during sliding connection. When the moving seat 3 moves along the direction of the track 1, the positioning pin 15 is retracted due to the extrusion on the inner side of the pin rail 16, and the positioning pin 15 slides along the direction of the pin rail 16, playing a certain guiding role and at the same time reducing the resistance when the moving seat 3 moves.

[0041] In this embodiment, preferably, the moving mechanism includes a control unit connected to the motor 5, a temperature sensing unit 17 arranged at intervals below the track 1, and a travel unit corresponding to the position of the temperature sensing unit 17. The temperature sensing unit 17 and the travel unit are connected to the control unit.

[0042] The moving mechanism includes a control unit, a temperature sensing unit 17, and a travel unit. The control unit can use a single-chip microcomputer and has the functions of receiving information and controlling execution. The temperature sensing unit 17 can use a temperature sensor and has the function of feedback temperature information. The travel unit can use an infrared sensor and has the function of feedback position information. The control unit is located in the moving seat 3 and is connected to the motor 5. The temperature sensing unit 17 is installed on the track 1 and is arranged downward facing the track 1. The travel unit is installed on the track 1 and is arranged inward facing the track 1. The temperature sensing units 17 are arranged at intervals along the direction of the track 1 and correspond to the positions of the travel units. The temperature sensing unit 17, the travel unit, and the control unit are connected. When a sudden fire occurs, the temperature sensing unit 17 above the fire point feeds back the current temperature information. The control unit compares the current temperature information with a preset temperature threshold. If it exceeds the preset temperature threshold, the control unit controls the motor 5 to start and drives the moving seat 3 to move until the travel unit feeds back that the moving seat 3 has reached the target position, and then the control unit controls the motor 5 to turn off, so that the fire extinguisher 2 moves to above the fire point by itself, realizing automatic control.

[0043] In this embodiment, preferably, the moving mechanism includes a limiting rod 18 arranged in parallel above the track 1. The cross-section of the limiting rod 18 is an L-shaped structure and is buckled with the top of the fixed seat 8.
