[0002] Forest fires are a serious problem. They not only cause great damage to the ecological environment but also may threaten the safety of human life and property. During the burning process of forest fires, a large amount of harmful gases will be generated. The main harmful gases include carbon monoxide (CO), carbon dioxide (CO2), sulfur dioxide (SO2), and various volatile organic compounds (VOCs), etc.

[0003] The concentrations of these gases in the air after a fire may increase sharply, causing damage to the human respiratory system, nervous system, etc., and even triggering poisoning incidents. Therefore, during a forest fire, it is very necessary to detect the gases generated after the fire. However, during the existing gas detection process, most can only detect at the edge of the fire and cannot perform multi-point detection on other parts of the fire, resulting in errors in the detected gases.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] As Figures 1 to 5 shown, the present utility model provides an unmanned aerial vehicle device for detecting forest fire dangerous gases with adjustable height. Among them, it includes a body 1. Mounting plates 2 are symmetrically arranged at the bottom of the body 1. A shaft body 3 rotatably connected is arranged between the two mounting plates 2. A cable 4 is wound around the shaft body 3 in circles. An optical fiber 5 is arranged inside the cable 4. By means of the arranged cable 4, the gas detector 8 can be retracted and extended, so that the gas component values at different heights in the fire can be detected, increasing the comprehensiveness of data collection.

[0026] An externally powered motor 6 is arranged outside one of the mounting plates 2. The output shaft of the motor 6 is connected to the shaft body 3. One end of the cable 4 extends below the body 1 and is connected to a stabilizing disk 7. A gas detector 8 is arranged at the bottom of the stabilizing disk 7. The optical fiber 5 is inserted into the interface of the gas detector 8. A signal transmitter 9 is arranged at the top of the body 1. The other end of the optical fiber 5 is connected to the signal transmitter 9.

[0027] On the top of the body 1, there is a signal lamp 10 connected to an external power supply. The signal lamp 10 is electrically connected to the signal transmitter 9. The signal lamp 10 can present various colors to warn of the degree of danger through different colors; yellow (medium danger), orange (high danger), and red indicate (extreme danger).

[0028] At the four corners of the bottom of the body 1, there are support rods 11 that slope outward. At the bottom of the support rods 11, there are landing disks 12.

[0029] Between the cable 4 and the optical fiber 5, there is a fireproof insulation layer 13. The thickness of the fireproof insulation layer is not less than the thickness of the cable 4. By setting the fireproof insulation layer 13, the situation where the optical fiber 5 is burned out can be effectively avoided, improving the safety of the optical fiber 5.

[0030] The cross-section of the stabilizing disk 7 is circular. On the annular wall of the stabilizing disk 7, there are symmetrically arranged hooks 14. On the hooks 14, there are hanging suspension rods 15. At the bottom of the suspension rods 15, there are heavy object balance blocks 16, which can keep the stabilizing disk 7 balanced during the flight of the drone. At the same time, it can also prevent the gas detector 8 from shaking caused by strong winds when detecting gases.

[0031] At the bottom of the stabilizing disk 7, there are symmetrically arranged mounting columns 17. Inside the mounting columns 17, there are movable lifting rods 18. On the lifting rods 18, there are fixing plates 19, and the fixing plates 19 are movably connected to the lifting rods 18.

[0032] On the opposite surfaces of the two fixing plates 19, there are load-bearing grooves 20. On the opposite surfaces of the two load-bearing grooves 20, there are anti-slip rubber strips 21. The anti-slip rubber strips 21 provided can increase the friction with the gas detector 8.

[0033] The opposite surfaces of the two anti-slip rubber strips 21 are inclined planes, and the distance between the two inclined planes gradually increases from bottom to top, better fixing the gas detector 8.

[0034] At the bottom of the fixing plate 19, there is a jacking spring 22 sleeved on the lifting rod 18. Under the action of the jacking spring 22, the fixing plate 19 will move upward, and the load-bearing groove 20 will be stuck on the gas detector 8, thus fixing the gas detector 8 and ensuring the stability during gas detection.

[0035] The detailed usage method and functions of the above embodiments:

[0036] When it is necessary to detect the fire gas in the forest, both ends of the cable 4 have interfaces. One end of the interface is fixed to the bottom of the stable plate 7 and inserted into the gas detector 8, and the other end of the interface is inserted into the signal transmitter 9. The fixing plate 19 is slidably mounted on the lifting rod 18. Move the fixing plate 19 downward, and the jacking spring 22 is compressed at this time. After the gas detector 8 is installed, move the fixing plate 19 upward. At this time, the jacking spring 22 rebounds, and both sides of the gas detector 8 will enter the bearing grooves 20 on the fixing plate 19. The anti-slip rubber strips 21 in the bearing grooves 20 will finally fit on both sides of the gas detector 8, so as to realize the fixation of the gas detector 8.

[0037] There is a heavy object balance block 16 at the bottom of the suspension rod 15. Hang the suspension rod 15 on the hooks 14 on both sides of the stable plate 7. At this time, start the drone. When it reaches the appropriate position, the motor 6 will drive the shaft body 3 to rotate, so that the cable 4 will be gradually lengthened, and the gas detector 8 will be lowered to the appropriate position. The detection contact of the gas detector 8 is located at the bottom, so as to detect the gas in the fire. After the detection is completed, the data will be transmitted to the signal transmitter 9 and sent out. Moreover, the signal lamp 10 can also receive the data from the signal transmitter 9 and emit light of different brightness according to the concentration components in the gas, so as to timely remind people. After the detection is completed, the drone can fly to other positions to realize multi-point position detection, so as to improve the accuracy of collecting data.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
