[0054] Correspondingly, the plurality of sliding tubes 103 are sequentially sleeved, so that the automatic lifting rod 10 has small volume in the retracted state, and is convenient for storage and transportation. The sleeving design between the fixed tube 102 and the plurality of sliding tubes 103 and the cooperation of the driving mechanism 101 make the lifting process stable and small in shaking, and ensure the safety of the lifting process. Wherein, the fixed tube 102 and the sliding tube 103 can be made of carbon fiber T300 material, so that the structure of the automatic lifting rod 10 meets the requirements of high strength and light weight.

Wherein, the winding and unwinding assembly can be arranged on the fixed tube 102, and the guide wheel set can be arranged on the plurality of sliding tubes 103.

[0056] Correspondingly, by controlling the winding or releasing state of the winding and unwinding assembly, the precise movement of the plurality of sliding tubes 103 in the vertical direction can be realized, so as to realize the precise control of the plurality of sliding tubes 103. And the winding and unwinding assembly and the traction assembly are compactly arranged on the fixed tube 102 and the plurality of sliding tubes 103, so that the automatic lifting rod 10 occupies smaller space and can be applied to various working environments. In addition, the traction rope always keeps a suitable path under the guidance of the guide wheel set, avoiding the swing or disengagement of the traction rope, and ensuring the stability and reliability of the lifting process.

The guide pulley set can include a first pulley arranged at the upper end of the fixed tube 102, a second pulley arranged at the lower end of each sliding tube 103, and a third pulley arranged at the upper end of each sliding tube 103; the second end of the traction rope is first wound around the first pulley, then sequentially wound around the second pulley and the third pulley on each sliding tube 103 in the outward-to-inward direction, and finally connected with the upper end of the innermost sliding tube 103. Of course, the driving mechanism 101 can also be other existing structures, such as the structure in CN102654278A.

[0058] In some embodiments, a plurality of lifting legs 16 are arranged below the support base 13, and the lifting legs 16 can be connected with the ground foundation through a bolt assembly. For example, the lifting legs 16 include four, and the four lifting legs 16 are arranged in a rectangular shape. Correspondingly, the lifting legs 16 are used to support the support base 13, and by the lifting cooperation of the plurality of lifting legs 16, the horizontal angle of the support base 13 can be adjusted according to the ground conditions, and then the vertical angle of the automatic lifting rod 10 is adjusted. The height of the lifting leg 16 can be adjusted according to the ground conditions, so that it can adapt to various complex terrains, including uneven terrains, to ensure the stability of the entire device and effectively reduce the safety hazards caused by uneven ground. The height of the lifting leg 16 can be manually adjusted, or a hydraulic or electric drive system can be provided to realize automatic adjustment.

[0059] For example, referring to Figure 5 , the lifting leg 16 includes a top plate 161, a connecting pipe 162, an adjusting rod 163 and a bottom plate 164 arranged in sequence from top to bottom, the bottom plate 164 is connected with the lower end of the adjusting rod 163, the upper end of the adjusting rod 163 is arranged in the inner cavity of the connecting pipe 162 and is threadedly connected with the connecting pipe 162, the upper end of the connecting pipe 162 is connected with the top plate 161, and the top plate 161 is connected with the bottom of the support base 13.

[0061] Correspondingly, the gimbal mounting plate 111, as an intermediate connecting component, can firmly mount the detector gimbal 112 and the detector device 12 on the upper end of the automatic lifting pole 10, ensuring the stability of the detector device 12 during lifting and rotating. The detector gimbal 112 can rotate in the horizontal and vertical directions, so that the detector device 12 can be monitored in all directions in multiple dimensions, which is particularly suitable for fire monitoring in complex environments.

[0063] In some embodiments, referring to Figure 4 , the support base 13 includes a support frame 131 arranged horizontally and a support plate 132 fixed on the top of the support frame 131. Correspondingly, the support frame 131 is usually made of high-strength material and has high carrying capacity, which can bear the weight of the automatic lifting pole 10 and its load. The support plate 132 is fixed on the top of the support frame 131, which further enhances the rigidity of the support base 13 and ensures that the device will not be deformed during operation due to external forces. At the same time, the support plate 132 also provides a large support area to facilitate the installation of components such as the automatic lifting pole 10 and the control cabinet 15.

[0064] In some embodiments, referring to Figure 1 , the lower end of the automatic lifting pole 10 is detachably connected with the support plate 132. Correspondingly, the detachable connection allows the automatic lifting pole 10 to be separated from the support base 13 during transportation, reducing the overall volume and facilitating transportation and storage. In the installation site, the automatic lifting pole 10 can be quickly connected with the support base 13 according to actual needs, simplifying the installation process and improving the installation efficiency. When a component of the automatic lifting pole 10 or the support base 13 is damaged, the detachable connection design allows quick replacement of the damaged component without the need to replace the entire device. For example, the lower end of the automatic lifting pole 10 is connected with the support plate 132 by a flange bolt structure.
