Description

Technical Field

[0001] The present invention relates to the technical field of chemical detection, and more specifically, to a toxic and harmful gas monitor suspended by a drone. Background Art

[0002] Existing toxic and harmful gas monitors have shown significant limitations in multiple 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. This not only limits the flexibility and efficiency of monitoring but also increases the risk of personnel exposure to potentially dangerous environments.

[0003] Secondly, regarding the monitoring range and accuracy, the coverage of existing monitors is limited, making it difficult to achieve comprehensive monitoring of complex environments such as gob areas. Moreover, under certain extreme conditions, their monitoring accuracy may be interfered by environmental factors, affecting the accuracy of data.

[0004] In addition, the emergency response ability is also a major shortcoming of existing monitors. Due to the lack of a perfect early warning mechanism and seamless connection with the emergency response system, they often react slowly in the face of emergencies and are unable to quickly guide on-site personnel to take effective measures to reduce accident risks. Finally, from the perspective of maintenance and upgrade costs, existing monitors need to be maintained and calibrated regularly, which not only increases maintenance costs and manpower input but also limits their ability to adapt to new technologies and new requirements. With the continuous progress of technology and the changing application scenarios, existing monitors face many difficulties in upgrading and expanding functions. In view of this, we propose a toxic and harmful gas monitor suspended by a drone. Summary of the Invention

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. By designing the drone mechanism and the control mechanism, the operator cooperates with the drone body and the drone remote controller on the ground or at the working surface, so that the drone body flies to the goaf where gas detection is required to monitor the gas in the goaf, and transmits the monitoring information and video images to the remote controller through the UWB positioning system and the 5G communication system, which greatly saves manpower and material resources, improves work efficiency, realizes the unmanned operation of high-risk work, and greatly improves the safety factor of underground work.

[0025] 2. The present invention also designs a sealing telescopic rod and a cover plate. After the drone body is placed in the storage box, the cover plate is closed. As the cover plate is closed, the sealing telescopic rod will be in a compressed state, so that the gas in the sealing telescopic rod enters the sealing cylinder along the connecting pipe. The pressure in the sealing cylinder increases, thereby pushing the piston and the sliding rod to discharge the cleaning brush, so that the device can discharge the cleaning brush by closing the cover plate. On the one hand, it can ensure the contact surface between the cleaning brush and the wing and ensure the cleaning effect on the wing. On the other hand, when the cover plate is opened, the gas in the sealing cylinder is discharged, and the spring drives the cleaning brush to reset. At this time, the cleaning brush will be retracted into the cover plate, thus avoiding the drone body from rubbing against the cleaning brush when the drone body is taken out, and reducing the possibility of damage to the wing caused by the cover plate and the storage box.

[0026] 3. The present invention also designs a transmission component. After the cover plate is closed, it is necessary to pull the limit rod to slide to the right. At this time, the limit rod will drive the transmission belt to move synchronously during the movement, and the transmission wheel and the installation component connected to the transmission belt will rotate at the same time. When the sealing cylinder rotates, it will drive the cleaning brush to rotate through the friction between the piston and the sliding rod, so as to ensure that after use, the device can automatically clean the toxic and harmful gases adhered to the wing surface, avoid the corrosion of the wing by the toxic and harmful gases, and thus ensure the service life of the device.

By designing the sealing telescopic rod and the cover plate, after the drone body 201 is placed in the storage box 101, the cover plate is closed. As the cover plate is closed, the sealing telescopic rod will be in a compressed state, so that the gas in the sealing telescopic rod enters the sealing cylinder 4022 along the communication pipe 407. 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 plate.

A transmission belt 4028 is arranged on the transmission wheel 4027. A spring 4029 is arranged inside the sealed cylinder 4022. By designing the transmission assembly 402, after the cover plate is closed, it is necessary to pull the limiting rod 405 to slide to the right. At this time, the limiting rod 405 will drive the transmission belt 4028 to move synchronously during the movement.

Thus, after use, the device can automatically clean the toxic and harmful gases adhered to the surface of the wing 205, avoid the corrosion of the toxic and harmful gases to the wing 205, and further ensure the service life of the device.

[0048] As another embodiment of the present invention, the two ends of the spring 4029 are fixedly connected to one side of the piston 4024 and one side of the inner wall of the sealing cylinder 4022, respectively.

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 on the outside of 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 can rotate. 93 gradually loosens the reeling of the steel cable 4094, and the elastic telescopic rod 4098 gradually squeezes the synchronization plate 4097 downward under the action of its own elastic force, thereby pushing the docking block 4099 to fit into the docking slot 309, completing the fixation of the drone remote control 301, so that the device can quickly loosen the cleaning of the drone body 201 and the fixation of the drone handle during use, and after use, the wing 205 can be quickly cleaned while the drone handle is fixed, ensuring the safety of carrying the drone body 201 and the drone handle.

[0049] Working Principle: This embodiment provides a toxic and harmful gas monitor based on drone suspension. The steps for use include:

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

[0051] 1.1. To remove the drone from the storage box 101, slide the limit rod 405 to the left. Then, flip the top cover 401 along the pin. When the top cover 401 is fully opened, the drone body 201 and the drone remote control 301 can be taken out.

[0052] 2. Take off the UAV body 201 by holding the remote controller on the ground, and check whether the functions of the UAV body 201 and the UAV remote controller 301 are normal;

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

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

[0055] 5. After completing the detection of toxic and harmful gases in the goaf, remotely control the UAV body 201 to return to the ground;

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

[0057] 6.1. After putting the UAV body 201 into the storage box 101, close the cover plate. As the cover plate closes, the sealing telescopic rod will be in a compressed state, so that the gas in the sealing telescopic rod will enter the sealing cylinder 4022 along the connecting pipe 407. 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 plate;

[0058] 6.2. After the cover plate is completely 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 mounting component 409 connected to the transmission belt 4028 will rotate at the same time. When the sealing cylinder 4022 rotates, it will drive the cleaning brush to rotate through the friction between the piston 4024 and the sliding rod 4023;

[0059] 6.3. When pulling the limit rod 405 to move in the chute 406 to drive the transmission belt 4028 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 push the synchronous plate 4097 to move downward under the action of its own elastic force, thereby pushing the docking block 4099 into the docking groove 309 to complete the fixation of the UAV remote controller 301.
