[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1:

[0027] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an unmanned aerial vehicle (UAV)-borne laser methane telemetry instrument, including a UAV body 1. A mounting plate 2 is fixedly connected to the bottom of the UAV body 1. A mounting column 3 is provided at the bottom of the mounting plate 2. A laser methane telemetry instrument body 4 for testing methane is provided at one end of the mounting column 3. A disassembly assembly 5 for installing and disassembling the mounting column 3 is provided on the outside of the mounting column 3. A main body assembly 10 is provided on one side of the laser methane telemetry instrument body 4.

[0028] The UAV body 1 generates lift by driving the propeller 17 with a motor, and performs attitude adjustment and navigation in conjunction with the flight control system to achieve autonomous or remote-controlled flight and complete various tasks. It is noted that the UAV body 1 is existing technology and will not be described in detail here. The design of the mounting plate 2 can not only be fixedly connected to the UAV body 1, but also install the sleeve 51. At the same time, the mounting column 3 facilitates the fixed connection with the mounting frame 13, so as to facilitate the connection of the laser methane telemetry instrument body 4.

[0029] The disassembly assembly 5 includes a sleeve 51 fixed to the bottom of the mounting plate 2. Two sets of sleeve rods 52 are fixedly connected to the inner wall of the mounting column 3. Slide rods 53 are slidably connected to the inner walls of the two sets of sleeve rods 52. A return spring 54 is fixedly connected to one end of each set of slide rods 53, and one end of the return spring 54 is fixedly connected to the inner wall of the sleeve rod 52.

[0030] Firstly, two sets of slots are provided on the inner wall of the sleeve 51. So when the mounting post 3 is inserted into the sleeve 51, due to the design of the slots and the reaction force of the return spring 54, when the sleeve rod 52 passes through the slot, the slide rod 53 is bounced to the slot by the return spring 54, which can easily connect the mounting post 3 and the sleeve 51, making the installation of the mounting post 3 and the sleeve 51 more convenient.

[0031] The main component 10 includes a first status indicator light 101 disposed on one side of the laser methane telemetry instrument body 4, a second status indicator light 102 disposed on one side of the laser methane telemetry instrument body 4, a laser emitting light 103 disposed on one side of the laser methane telemetry instrument body 4, a ranging module 104 disposed on one side of the laser methane telemetry instrument body 4, and a laser receiving module 105 disposed on one side of the laser methane telemetry instrument body 4.

[0032] When the laser methane telemetry instrument body 4 is working, the first status indicator 101 and the second status indicator 102 display the instrument's working status and power information, respectively. The laser emitting lamp 103 emits infrared laser light, the ranging module 104 measures the laser transmission distance, and the laser receiving module 105 receives the reflected light and calculates the methane concentration. It should be noted that the first status indicator 101, the second status indicator 102, the laser emitting lamp 103, the ranging module 104, and the laser receiving module 105 are all existing technologies and will not be described in detail here.

[0033] Example 2:

[0034] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, a first limiting spring 6 is fixedly connected to the inner wall of the sleeve 51, and a first reset block 7 is fixedly connected to one end of the first limiting spring 6.

[0036] The first limit spring 6 uses its own reaction force to easily pop out the first reset block 7. When the first reset block 7 pops out, it abuts against the second reset block 8.

[0037] Specifically, a second reset block 8 is provided at the bottom of the first reset block 7, and the structure of the second reset block 8 is the same as that of the first reset block 7. A second limiting spring 9 is fixedly connected to the bottom of the second reset block 8, and one end of the second limiting spring 9 is fixedly connected to the inner wall of the mounting column 3. A fixing frame 20 is fixedly connected to the outer side of the sleeve 51. A positioning tube 21 is fixedly connected to the inner wall of the fixing frame 20. A moving tube 22 is slidably connected to the inner wall of the positioning tube 21. A limiting plate 23 for pushing the slide rod 53 is fixedly connected to one end of the moving tube 22. A third limiting spring 24 is fixedly connected to the inner wall of the positioning tube 21, and one end of the third limiting spring 24 is fixedly connected to one end of the moving tube 22.

[0038] By setting the second reset block 8, it is easy to connect with the second limit spring 9. The principle of the second reset block 8 and the second limit spring 9 is the same as that of the first limit spring 6 and the first reset block 7. By setting the fixing bracket 20, it is easy to install the positioning tube 21. By setting the positioning tube 21, it is easy to install the third limit spring 24. By setting the moving tube 22, it is easy to fix and connect with the limit plate 23. The third limit spring 24 can easily slide the moving tube 22 inside the positioning tube 21, thereby facilitating the reset and movement of the limit plate 23 to push the slide rod 53.

[0039] Specifically, a fixing block 11 is fixedly connected to one side of the laser methane telemetry instrument body 4, a connecting shaft 12 is rotatably connected to the inner wall of the fixing block 11, a mounting bracket 13 is fixedly connected to the outer side of the connecting shaft 12, and the top of the mounting bracket 13 is fixedly connected to one end of the mounting column 3.

[0040] The design of the fixing block 11 facilitates the rotation of the connecting shaft 12. At the same time, since the mounting bracket 13 is installed on the outside of the connecting shaft 12, it is also possible to achieve the effect of rotating the mounting bracket 13.

[0041] Example 3:

[0042] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, multiple sets of mounting rods 14 are installed on the outside of the drone body 1. Each set of mounting rods 14 has a positioning block 15 fixedly connected to its top, and the positioning block 15 is positioned towards the end of the mounting rod 14 that is away from the drone body 1.

[0044] The design of setting multiple sets of mounting rods 14 facilitates the fixing of the positioning block 15. The positioning block 15 is set at the end of the mounting rod 14 away from the UAV body 1, so that all the propellers 17 are on the outermost side, resulting in better flight performance. The positioning block 15 also facilitates the installation of the connecting column 16.

[0045] Specifically, a connecting post 16 is installed on the top of the positioning block 15, and a propeller 17 for takeoff is installed on the outside of the connecting post 16.

[0046] The propeller 17 is mounted on the outside of the connecting column 16. The propeller 17 of the UAV body 1 generates lift and thrust by rotating, which propels the UAV body 1 to fly. It should be noted that the propeller 17 is existing technology and will not be described in detail here.

[0047] Specifically, the bottom of the drone body 1 is fixedly connected to two sets of support rods 18, and the two sets of support rods 18 are designed symmetrically. One end of each set of support rods 18 is fixedly connected to a support column 19.

[0048] The design of fixing the support rod 18 and the support column 19, and the fact that the whole is in two sets, makes it easy for the drone body 1 to land smoothly.

[0049] In use, the drone body 1 flies by rotating the propeller 17 driven by the motor, generating lift and thrust. Combined with the flight control system, it adjusts its attitude to achieve autonomous or remote-controlled flight. The laser methane remote detector body 4 utilizes the principle of laser spectroscopy, emitting a laser beam of a specific wavelength to irradiate the gas, detecting the intensity change after the laser is absorbed by methane, thereby calculating the methane concentration, achieving remote, non-contact methane leak detection. The first status indicator 101 and the second status indicator 102 display the instrument status. The laser emitting light 103 emits infrared laser to the detection point, the ranging module 104 measures the distance, and the laser receiving module 105 receives the reflected laser beam. Through processing and analysis, the methane concentration is obtained. The entire process achieves long-distance, high-precision methane detection. Before the drone takes off, the laser methane remote detector body 4 needs to be installed. First, the mounting bracket 13 is installed on the outside of the laser methane remote detector body 4, and then... The mounting post 3 is installed on the mounting bracket 13. The operator holds the mounting post 3 and inserts it into the sleeve 51. At this time, the return spring 54 is in a retracted state when the mounting post 3 is inserted into the sleeve 51. When the sliding rod 53 is inserted into the through hole in the sleeve 51, the return spring 54 causes the sliding rod 53 to spring up, and the sliding rod 53 will be inserted into the through hole in the sleeve 51, thus completing the installation of the laser methane telemetry instrument body 4. When the laser methane telemetry instrument body 4 needs to be disassembled, the operator only needs to pull the moving tube 22. The movement of the moving tube 22 causes the third limiting spring 24 in the positioning tube 21 to extend. After the moving tube 22 moves, it will cause the limiting plate 23 to move laterally. After the limiting plate 23 moves, it will push the sliding rod 53 out of the through hole in the sleeve 51. The return spring 54 then retracts. Then, the mounting post 3 is pulled down to remove the mounting post 3 from the sleeve 51, and the laser methane telemetry instrument body 4 can be disassembled.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
