Description

Technical Field

[0001] The present invention relates to the field of chemical detection technology, and more specifically, to a toxic and harmful gas monitor based on unmanned aerial vehicle suspension. Background Art

[0002] Existing toxic and hazardous gas monitors have shown significant limitations in several key areas. First, in terms of automation and intelligence, they often rely on manual operation and lack the intelligent capabilities of autonomous patrol and fixed-point monitoring, which not only limits the flexibility and efficiency of monitoring, but also increases the risk of personnel being exposed to potentially dangerous environments.

[0003] Secondly, in terms of monitoring range and accuracy, the existing monitoring instruments have limited coverage, making it difficult to achieve comprehensive monitoring of complex environments such as goafs. Moreover, under certain extreme conditions, their monitoring accuracy may be affected by environmental factors, affecting the accuracy of the data.

[0004] In addition, emergency response capability is also a major shortcoming of existing monitors. Due to the lack of a complete early warning mechanism and seamless connection with the emergency response system, they often react slowly when faced with emergencies and are unable to quickly guide on-site personnel to take effective measures to reduce the risk of accidents. Finally, from the perspective of maintenance and upgrade costs, existing monitors require regular maintenance and calibration, which not only increases maintenance costs and manpower investment, but also limits their ability to adapt to new technologies and new needs. With the continuous advancement of technology and the continuous changes in application scenarios, existing monitors face many difficulties in upgrading and expanding functions. In view of this, we propose a toxic and hazardous gas monitor based on drone suspension. Summary of the invention

[0049] Working principle: This embodiment provides a toxic and harmful gas monitor based on drone suspension, and the use steps include:

[0050] 1. Turn on the power of the drone body 201 and the drone remote controller 301;

[0051] 1.1. When taking the drone out of the storage box 101, the limit rod 405 needs to be slid to the left, and the top cover 401 is flipped along the pin shaft. When the top cover 401 is fully opened, the drone body 201 and the drone remote control 301 can be taken out;

[0052] 2. On the ground, hold the remote control to control the UAV body 201 to take off, and check whether the functions of the UAV body 201 and the UAV remote control 301 are normal;

[0053] 3. Remotely control the UAV body 201 to enter the goaf to perform gas monitoring;

[0054] 4. Regularly record the position information of the drone body 201 and the concentration information of toxic and harmful gases on the drone remote controller 301;

[0055] 5. After the detection of toxic and harmful gases in the goaf is completed, the drone body 201 is remotely controlled to return to the ground;

[0056] 6. Turn off the power of the drone body 201 and the drone remote controller 301 and put them back into the storage box 101 for next use;

[0057] 6.1. After placing the drone body 201 in the storage box 101, the cover is closed. As the cover is closed, the sealing telescopic rod is in a compressed state, so that the gas in the sealing telescopic rod enters the sealing cylinder 4022 along the connecting pipe 407, and the pressure in the sealing cylinder 4022 increases, thereby pushing the piston 4024 and the sliding rod 4023 to discharge the cleaning brush, so that the device can discharge the cleaning brush by closing the cover;

[0058] 6.2. After the cover is closed, it is necessary to pull the limit rod 405 to slide to the right. At this time, the limit rod 405 will drive the transmission belt 4028 to move synchronously during the movement, and the transmission wheel 4027 and the installation assembly 409 connected to the transmission belt 4028 will rotate at the same time. When the sealing cylinder 4022 rotates, the friction between the piston 4024 and the sliding rod 4023 drives the cleaning brush to rotate;

[0059] 6.3. When the limit rod 405 is pulled to move in the slide groove 406 and the transmission belt 4028 is driven to move, the friction wheel 4092 arranged outside the transmission belt 4028 will rotate synchronously. At this time, the friction wheel 4092 will drive the winding roller 4093 to rotate through the rotator 4091, so that the winding roller 4093 gradually loosens the winding of the steel cable 4094, and the elastic telescopic rod 4098 will gradually squeeze the synchronous plate 4097 downward under the action of its own elastic force, thereby pushing the docking block 4099 to be stuck in the docking groove 309, thereby completing the fixation of the drone remote control 301.
