[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0028] like Figures 1-3As shown, this application discloses a gas pipeline inspection drone, which includes a drone body 1, a control module 2 at the center of the drone body 1, propellers 3 for lifting and moving at the four corners of the drone body 1, and a high-definition camera 4 at the front end of the drone body 1.
[0029] A mounting platform 5 is horizontally arranged at the lower center of the main body 1 of the drone, and an internally threaded sleeve 6 is provided on the upper side of each of the four corners of the mounting platform 5.
[0030] The upper end of the internal threaded sleeve 6 is fixedly connected to the bottom of the shell of the UAV body 1. A first fastening bolt 7 is inserted into each of the four corners of the mounting platform 5. The first fastening bolt 7 passes through the mounting platform 5 from bottom to top and is inserted into the internal threaded sleeve 6 at the corresponding position and the two are threadedly connected.
[0031] The gas pipe detection device 9 is installed on the lower side of the mounting platform 5 via a hanger 8.
[0032] In the above embodiments, a mounting platform 5 is provided at the lower center of the drone body 1. Each of the four corners of the mounting platform 5 has an internally threaded sleeve 6 fixedly connected to the drone body 1. The four corners of the mounting platform 5 and the internally threaded sleeves 6 are connected by first fastening bolts 7. A gas pipe detection device 9 is mounted on the lower side of the mounting platform 5 via a hanger 8. Threaded connection is a common detachable method. When maintenance personnel need to replace other types of gas pipe detection devices 9 under the drone body 1, they can remove the four first fastening bolts 7 sequentially from the four internally threaded sleeves 6 under the drone body 1. At this time, the mounting platform 5 can be separated from the drone body 1 so that the personnel can remove the mounting platform 5 and the gas pipe detection device 9 together. Then, the other type of gas pipe detection device 9 is replaced onto the hanger 8 under the mounting platform 5, and the new gas pipe detection device 9 is reinstalled onto the drone body 1 using the first fastening bolts 7 to complete the replacement work. The detachable mounting platform 5 located below the main body 1 of the drone in this application allows for easy replacement of different gas pipe detection devices 9 by simple bolt installation and removal when staff need to change them. This effectively improves the convenience of using the drone for gas pipeline inspection. Compared with some existing integrated drones that lack expansion capabilities, the drone in this application is more flexible and has a wider range of applications. When different detection functions are required, it is not necessary to replace the entire drone equipment; only the different gas pipe detection devices 9 need to be replaced at the bottom of the main body 1. This also saves on equipment operating costs to a certain extent.
[0033] Furthermore, such as Figures 1-3As shown, two landing gears 10 are symmetrically installed on the lower side of the main body 1 of the drone, and the two landing gears 10 are located on one opposite side of the gas pipe detection device 9, with the lower end of the landing gear 10 being lower than the lowest point of the gas pipe detection device 9.
[0034] In the above embodiments, the two landing gears 10 on the underside of the drone are arranged in the manner described above, which can ensure that the landing gears 10 provide a certain degree of protection for the gas pipe detection device 9 when the drone descends to the ground or when the underside of the drone comes into contact with an obstacle during flight.
[0035] Furthermore, such as Figure 2 As shown, the hanger 8 includes a central sleeve 81 with internal threads. The upper side of the central sleeve 81 is fixedly connected to the mounting platform 5. The lower side of the central sleeve 81 is provided with a mounting seat 82. A second fastening bolt 83 is inserted into the center of the top plate of the mounting seat 82. The second fastening bolt 83 passes through the top plate of the mounting seat 82 and is inserted into the central sleeve 81, and the two are threadedly connected.
[0036] The mounting base 82 has multiple mounting holes. The equipment frame 84 is fixedly installed at the mounting holes of the mounting base 82 by multiple bolts and nuts. The gas pipe detection device 9 is installed on the lower side of the equipment frame 84.
[0037] In the above embodiments, the mounting base 82 in the hanger 8 of this application is mounted on the central sleeve 81 by the second fastening bolt 83. The hanger 8 increases the distance between the gas pipe detection device 9 and the drone body 1, thereby reducing the risk that the gas pipe detection device 9 will have its view obstructed by some components on the drone body 1 during use. The mounting base 82 and the gas pipe detection device 9 are connected by multiple bolts and nuts. The drone body 1 of this application has multiple freely detachable points on its lower side. In actual use, the operator can not only freely install and remove the hanger 8 and the gas pipe detection device 9 from the mounting platform 5, but also freely install and remove them at the connection between the hanger 8 and the mounting platform 5, and at the connection between the mounting base 82 and the equipment frame 84 in the hanger 8. This can further improve the flexibility of the drone of this application in combining with different equipment in actual use.
[0038] Furthermore, such as Figures 1-3 As shown, the equipment frame 84 includes a horizontal plate 841 and a side plate 842. The lower end of the side plate 842 is fixedly connected to the upper side of one end of the horizontal plate 841. A reinforcing plate 843 is added between the side plate 842 and the horizontal plate 841. A third fastening bolt 844 is inserted at the position corresponding to the reserved hole on the housing of the gas pipe detection equipment 9 on the lower side of the horizontal plate 841. The third fastening bolt 844 passes through the horizontal plate 841 and is inserted into the reserved hole on the housing of the gas pipe detection equipment 9, and the two are threaded together.
[0039] In the above embodiments, the reinforcing ribs between the horizontal plate 841 and the side plate 842 can increase the connection strength between them. The position on the mounting base 82 connected to the equipment frame 84 by bolts and nuts is the side plate 842 in the equipment frame 84. The horizontal plate 841 provides a mounting platform for the horizontally set gas pipe detection device 9 based on the side plate 842, which can keep it in a horizontal state during use. The reserved holes at the four corners of the housing of the gas pipe detection device 9 are provided with internal threads. The third fastening bolt 844 passes through the horizontal plate 841 from top to bottom and is inserted into the reserved hole of the gas pipe detection device 9. The threaded connection with the reserved hole on the housing of the gas pipe detection device 9 can ensure that the gas pipe detection device 9 is sufficiently stable during use.
[0040] Furthermore, such as Figures 1-3 As shown, there is a gap between the horizontal plate 841 and the gas pipe detection device 9, and a rubber gasket 11 is fitted on the part of the third fastening bolt 844 located between the horizontal plate 841 and the gas pipe detection device 9.
[0041] In the above embodiments, the rubber spacer set between the horizontal plate 841 and the gas pipe detection device 9 in the manner described above can prevent contact wear between the housing of the gas pipe detection device 9 and the horizontal plate 841 during use.
[0042] Furthermore, such as Figure 2 and Figure 3 As shown, the mounting base 82 has an inverted L-shaped structure. The side plate 842 of the equipment frame 84 is connected to the vertical section of the mounting base 82 by bolts and nuts. The overlapping area of the side plate 842 and the vertical section of the mounting base 82 is provided with airflow passage holes 12.
[0043] In the above embodiments, the mounting base 82 of this application is configured as an inverted L-shaped structure. The notch on the front side of the mounting base 82 provides sufficient operating space when the operator installs the side plate 842 of the equipment frame 84 onto the mounting base 82. The airflow passage hole 12 provided in the overlapping area of the vertical section of the side plate 842 and the mounting base 82 facilitates the smooth passage of airflow during the flight of the UAV body 1, thereby reducing the flight drag of the UAV.
[0044] Furthermore, such as Figure 2 As shown, two diagonal tie rods 13 are added between the vertical and horizontal sections of the mounting base 82.
[0045] In the above embodiments, after the mounting base 82 and the equipment rack 84 of the present application are connected together, they can form a "C" shape. During the flight of the UAV main body 1, the vertical section of the mounting base 82 will bear a relatively large bending moment during the flight of the UAV main body 1, which will increase the risk of its deformation. However, in the present application, by adding two diagonal braces 13 to the vertical section and the horizontal section of the mounting base 82, the overall strength of the mounting base 82 can be effectively improved, thereby reducing the risk of deformation during its use.
[0046] Furthermore, as Figure 1 and Figure 2 shown, the stiffening plates 843 and the horizontal plates 841 of the equipment rack 84 are both designed with hollow-out structures.
[0047] In the above embodiments, the stiffening plates 843 and the horizontal plates 841 of the present application are both made into hollow-out designs, which can not only improve the air flow channels around the gas pipeline detection device 9, increase the heat dissipation effect during its use, but also reduce the overall weight of the equipment rack 84 and reduce the load during the flight of the UAV main body 1.
[0048] Furthermore, as Figure 1 and Figure 2 shown, the windward side of the stiffening plate 843 is a circular arc structure.
[0049] In the above embodiments, the windward side of the stiffening plate 843 of the present application faces the side of the UAV main body where the high-definition camera 4 is installed. The side of the UAV main body 1 where the high-definition camera 4 is installed is also its front side. Setting the windward side of the stiffening plate 843 as a circular arc structure or a streamlined structure can enhance the separation of the air flow below the UAV main body 1 during the flight with the UAV main body 1, so that these air flows evenly pass through the air flow through holes 12 on the side plate 842 and the mounting base 82. At the same time, the resistance received by the stiffening plate 843 set in the above manner during flight can also be effectively reduced.
[0050] Furthermore, the high-definition camera 4 is a multi-angle camera.
[0051] In the above embodiments, the high-definition camera 4 at the front end of the UAV main body 1 of the present application is a multi-angle camera, which can facilitate the UAV main body 1 to flexibly obtain image information of the surrounding environment or gas pipelines as needed. For example, when using the gas pipeline detection device 9 to find the area where the gas pipeline has problems, photos can be taken from multiple directions through the multi-angle camera to obtain evidence of the problem area of the gas pipeline, so that subsequent staff can find the problem area of the gas pipeline according to the image data for repair.
[0052] The implementation principle of this embodiment is as follows: Before use, the selected gas pipe detection device 9 is first connected to the horizontal plate 841 of the equipment frame 84 using the third fastening bolt 844. Then, the horizontal section of the mounting base 82 is fixed to the mounting platform 5 under the drone body 1 using the second fastening bolt 83. Finally, the worker lifts the gas pipe detection device 9 so that the side plate 842 of the equipment frame 84 and the vertical section of the mounting base 82 come into contact. After aligning the reserved holes on both, they are fixed together using multiple pairs of bolts and nuts, thus completing the initial installation of one type of gas pipe detection device 9 on the drone body 1. When it is necessary to replace other types of gas pipe detection devices 9, the worker can refer to the above installation sequence and select to remove the bolts of the corresponding parts according to actual needs, and then replace them with new gas pipe detection devices 9. The drone body 1 of this application has multiple positions for installation and removal using bolts. In actual use, the worker can not only freely install and remove the required type of gas pipe detection device 9, but also has a variety of flexible installation and removal methods, which can effectively improve the convenience of using the drone of this application.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
