The utility model belongs to the field of fire detection and positioning technology, and in particular, a positioning mechanism for fire detection. In view of the problem that the existing fire hydrants are inconvenient to fix and cannot be adjusted after fixation, and need to be released for adjustment, which reduces work efficiency, the following scheme is proposed, which includes a base box, a winding mechanism is provided in the base box, and two adjusting rods are connected to the winding mechanism. The tops of the two adjusting rods are connected to a clamping seat, and two strip holes are provided on the top of the base box.

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] Reference Figure 1-4 , a positioning mechanism used for fire detection, plays a vital role in the field of fire detection.
[0022] As one of the core components of the mechanism, the positioning ring 1 plays a key role in connecting and supporting the other components. Multiple support legs 3 are mounted on the positioning ring 1, providing stable support for the entire positioning mechanism, ensuring stability in various complex testing environments.
[0023] The support legs 3 are usually made of high-strength materials, have good load-bearing capacity and stability, and can withstand various forces to which the positioning mechanism is subjected during operation.
[0024] The positioning ring 1 houses an annular rotating chamber 8 and an annular transmission chamber 9. The annular rotating chamber 8 accommodates the rotation of multiple adjusting screws 10, allowing them to rotate freely within it. The annular transmission chamber 9, responsible for transmitting power, houses key components such as the rotating ring 11 and the adjusting motor 14.
[0025] Multiple adjusting screws 10 are rotatably disposed within the annular rotating chamber 8 and extend into the annular transmission chamber 9. The movable frame 4 in the connection mechanism is threadedly sleeved on the adjusting screws 10. The movable frame 4 is designed in a U-shape, which can not only closely cooperate with the adjusting screws 10 to achieve stable thread transmission, but also provide good connection and support for the positioning wheel 5.
[0026] The positioning wheel 5 is rotatably connected to the movable frame 4 so that the positioning wheel 5 can be adjusted along with the movable frame 4 , thereby adapting to positioning detection of fire pipes 2 of different sizes.
[0027] A rotating ring 11 is rotatably mounted within the annular transmission chamber 9. This rotating ring 11 is a key component in power transmission. An adjustment motor 14 is also fixedly mounted within the annular transmission chamber 9 and connected to the rotating ring 11 via a rotating mechanism. A driving gear 15 within the rotating mechanism is mounted on the adjustment motor 14. A side ring gear 16 is mounted on the rotating ring 11 and meshes with the driving gear 15. When the adjustment motor 14 is activated, the driving gear 15 rotates the side ring gear 16, thereby rotating the rotating ring 11 within the annular transmission chamber 9.
[0028] The transmission mechanism includes a transmission gear 13 mounted on the adjustment screw 10. A surface gear ring 12 is provided on the rotating ring 11, meshing with the transmission gear 13. When the rotating ring 11 rotates, the surface gear ring 12 drives the transmission gear 13, which in turn rotates the adjustment screw 10 within the annular rotating chamber 8. In this way, the power of the adjustment motor 14 is transmitted to the adjustment screw 10, achieving position adjustment of the positioning wheel 5.
[0029] One of the movable frames 4 is provided with a moving motor 7 connected to the positioning wheel 5, and the moving motor 7 can provide power for the positioning wheel 5, so that the positioned fire-fighting pipe 2 can be moved, thereby improving the detection efficiency and flexibility.
[0030] Each positioning wheel 5 is equipped with a protective cover 6 made of rubber, which offers excellent elasticity and wear resistance. This rubber cover 6 effectively reduces the friction of the fire pipe 2. Furthermore, the surface of the cover 6 features anti-slip grooves, which increase the friction between the positioning wheel 5 and the fire pipe 2, ensuring smooth movement of the fire pipe 2.
[0031] When the utility model is used, Figure 1 As shown, the fire-fighting pipe 2 is in the positioning ring 1, and the multiple positioning wheels 5 can spread away or shrink close to achieve the clamping and positioning of the fire-fighting pipe 2. Therefore, the device can adapt to the clamping and positioning of fire-fighting pipes 2 of various sizes within a certain range. After clamping and positioning, the mobile motor 7 can be started, and the mobile motor 7 can drive one of the positioning wheels 5 to rotate. When the positioning wheel 5 rotates, the fire-fighting pipe 2 can be moved relative to the positioning ring 1. The operator standing near the positioning ring 1 does not need to move to realize the overall detection of the fire-fighting pipe 2.
[0032] The steps for spreading the multiple positioning wheels 5 away or shrinking them are as follows: starting the adjusting motor 14, the adjusting motor 14 can drive the driving gear 15 to rotate, the driving gear 15 can cooperate with the side ring gear 16 to drive the rotating ring 11 to rotate, and the rotating ring 11 can drive the adjusting screw 10 to rotate with the help of the surface ring gear 12 and the transmission gear 13. When the adjusting screw 10 rotates, the movable frame 4 can drive the positioning wheels 5 to complete the position adjustment.
[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
