The T-shaped guide rod 15 is located above the L-shaped extrusion seat 16 and cooperates with the L-shaped extrusion seat 16. The rectangular clamping rod 11, the fixing ring 13, the spring 12, the fixed pulley 14, the soft steel wire rope and the T-shaped guide rod 15 cooperate with each other. The rectangular clamping rod 11 and the rectangular clamping sleeve 101 are clamped and locked to the atmospheric data acquisition device body 1.

When the T-shaped guide rod 15 moves down to contact the L-shaped extrusion seat 16, it is blocked and restricted by the L-shaped extrusion seat 16. The carrier plate 9 that continues to move downward drives the fixed pulley 14 downward through the fixing ring 13 to squeeze the soft steel wire rope. The soft steel wire rope slides at the bottom of the fixed pulley 14 and pulls the rectangular clamping rod 11 to the right to separate from the rectangular clamping sleeve 101 and compress the spring 12, so as to achieve the effect of automatic release when it moves down to a low position.
[0031] The method of use of this embodiment is as follows: wherein the principle of using the atmospheric data collection device body 1 and its own components to collect atmospheric data is a prior art, and this composition and technology have also been disclosed in the above-mentioned prior art, and will not be further elaborated on;
[0032] When the atmospheric data acquisition device body 1 needs to be maintained, the personnel use the external remote control to operate the wireless remote control switch to control the driving motor 7 to start in reverse, the driving motor 7 drives the screw 6 to rotate, the screw 6 rotates to drive the lifting seat 5 to move downward, the lifting seat 5 drives the rectangular sliding sleeve 4 to move downward, and compresses the telescopic dustproof rubber sleeve 8, the rectangular sliding sleeve 4 drives the carrier plate 9 to move downward, and the carrier plate 9 drives the atmospheric data acquisition device body 1 to move downward to a low position, so that the atmospheric data acquisition device body 1 can be moved to a low position for personnel to inspect and maintain during maintenance, without the need for personnel to climb up to operate, thereby reducing the safety risks caused by climbing up and improving the safety of operation;
[0033] When the carrier plate 9 moves downward, it also drives the T-shaped guide rod 15 to move downward as a whole. When the T-shaped guide rod 15 moves downward to contact the L-shaped extrusion seat 16, it is blocked and restricted by it. At this time, the carrier plate 9 that continues to move downward drives the fixed pulley 14 to squeeze the soft steel wire rope downward through the fixed ring 13. Under the extrusion force, with the dragging effect of the T-shaped guide rod 15 when it is motionless, the soft steel wire rope slides at the bottom of the fixed pulley 14 and pulls the rectangular clamping rod 11 to the right to separate from the rectangular clamping sleeve 101. The rectangular clamping rod 11 compresses the spring 12 to release the clamping state of the rectangular clamping sleeve 101. At this time, the atmospheric data acquisition device body 1 can be directly pulled upward to drive the rectangular clamping sleeve 101 to separate from the carrier plate 9. The disassembly is completed, so that it is convenient to automatically unlock the atmospheric data acquisition device body 1 when it moves down to a low position, so that personnel can directly and conveniently disassemble the atmospheric data acquisition device body 1 without tools, thereby improving the convenience of disassembly, assembly, removal and maintenance work;
[0034] When installing after maintenance, the atmospheric data acquisition device body 1 is moved down to drive the rectangular clamping sleeve 101 to be stuck in the rectangular clamping hole 901. At this time, the personnel starts the driving motor 7 in the forward direction. Similarly, the movement direction of the driving motor 7 is completely opposite to the above-mentioned reverse start. At this time, the rectangular sliding sleeve 4 is transformed into an upward return movement and stretches the telescopic dustproof rubber sleeve 8. At this time, the carrier plate 9 is transformed into an upward movement and drives the atmospheric data acquisition device body 1 to rise upward. The carrier plate 9 also drives the T-shaped guide rod 15 to gradually separate from the L-shaped extrusion seat 16. The elastic force of the spring 12 in the compressed state drives the rectangular clamping rod 11 to automatically move back to the left and be stuck in the rectangular clamping sleeve 101, so as to achieve its clamping and locking, so that it is convenient to automatically clamp and lock the atmospheric data acquisition device body 1 when it is raised after maintenance, without the need for personnel to perform fixing operations separately, which is convenient for disassembly and assembly; in addition, when used for elevated monitoring, the telescopic dustproof rubber sleeve 8 is used to surround the inside of the circular support rod 3 and the screw 6 on the outside to prevent dust from entering and causing jamming, thereby ensuring the subsequent long-term and stable operation of the screw 6.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
