[0002] Helicopter surveying and mapping refers to the process of using a helicopter as a platform to carry various surveying and mapping equipment to collect data and obtain images of the ground or specific targets. This technology is widely used in multiple fields such as topographic surveying, geographic information collection, environmental monitoring, and disaster assessment. The core technology of helicopter surveying and mapping includes aerial photogrammetry. This method is to continuously photograph the ground using aerial photography instruments on the helicopter, and through these image data, topographic maps or other relevant maps can be drawn. Aerial photogrammetry is one of the most common and important technical means in helicopter surveying and mapping.

Two symmetrical support frames are fixedly connected to the lower surface of the drone body. A camera structure is fixedly installed on the lower surface of the drone body, which can self-adjust the balance and prevent the occurrence of rollover. It is supported by a movable support plate and a buffer plate, making the landing process more stable. However, its camera structure is fixedly installed on the lower surface of the drone body, which is not convenient for disassembly and has low applicability. Therefore, the utility model proposes a helicopter surveying and mapping device with a stable support structure to solve the above problems. Content of the Utility Model

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a helicopter measurement and mapping device with a stable support structure, including a body mounting plate 1 and a support frame 2 installed at the lower end of the body mounting plate 1. The body mounting plate 1 is used to support the helicopter body. A mounting plate 3 is fixedly installed at the lower end of the body mounting plate 1. Limiting components 6 are symmetrically arranged on the mounting plate 3. Fixing components 7 are symmetrically arranged on the mounting plate 3. An instrument base 5 is arranged on the mounting plate 3. An aerial photography instrument 4 is fixedly arranged on the instrument base 5. The limiting component 6 includes a fixing plate 61 fixedly installed on the mounting plate 3. The fixing component 7 includes a moving groove 71 opened on the mounting plate 3. By setting the limiting component 6 and the fixing component 7, under the multiple limiting and fixing of the moving block 72, the pressing block 73 and the limiting displacement plate 62, the stability of the instrument base 5 is ensured, and thus the stability of the aerial photography instrument 4 is improved, which facilitates the installation and disassembly of the aerial photography instrument 4. Since the moving block 72, the pressing block 73 and the limiting displacement plate 62 can move, it is convenient to install and fix instrument bases 5 of different sizes, and the applicability is improved.

[0021] A bidirectional threaded rod 77 is rotatably connected inside the moving groove 71. Moving blocks 72 are symmetrically arranged on the bidirectional threaded rod 77. The moving blocks 72 are slidably connected inside the moving groove 71. The moving blocks 72 are threadedly connected to the bidirectional threaded rod 77. One end of the bidirectional threaded rod 77 extends out of the moving groove 71 and is fixedly connected to a connection knob 78. A pressing block 73 is slidably connected inside the moving block 72. A second threaded rod 75 is rotatably connected to the pressing block 73. The second threaded rod 75 passes through the moving block 72 and is threadedly connected to the moving block 72. One end of the second threaded rod 75 away from the pressing block 73 is fixedly connected to a connection column 76. By rotating the connection knob 78, the connection knob 78 drives the bidirectional threaded rod 77 to rotate. Since the moving blocks 72 are threadedly connected to the bidirectional threaded rod 77, the rotation of the bidirectional threaded rod 77 drives the two moving blocks 72 to approach each other. Both of the two moving blocks 72 contact the instrument base 5, performing a preliminary limit on the instrument base 5. Then, by respectively rotating the connection columns 76 on both sides, the connection columns 76 drive the second threaded rods 75 to rotate, further driving the pressing blocks 73 to slide on the moving blocks 72, realizing the limit fixation of the pressing blocks 73 on the instrument base 5.

[0022] A sliding rod 63 is slidably connected to the fixing plate 61. One end of the sliding rod 63 is fixedly connected to a limit displacement plate 62. A first threaded rod 64 is rotatably connected to one end of the limit displacement plate 62 close to the fixing plate 61. The first threaded rod 64 passes through the fixing plate 61 and is threadedly connected to the fixing plate 61. One end of the first threaded rod 64 away from the limit displacement plate 62 is fixedly connected to a rotation knob 65. By rotating the rotation knob 65, the rotation knob 65 drives the first threaded rod 64 to rotate. The first threaded rod 64 drives the limit displacement plate 62 to contact the instrument base 5, realizing the re-fixation of the instrument base 5.

[0023] Working principle: During actual use, when installing the aerial photography instrument 4, the instrument base 5 is closely attached to the lower end of the installation plate 3. Rotate the connection knob 78. The connection knob 78 drives the bidirectional threaded rod 77 to rotate. Since the moving blocks 72 are threadedly connected to the bidirectional threaded rod 77, the rotation of the bidirectional threaded rod 77 drives the two moving blocks 72 to approach each other. Both of the two moving blocks 72 contact the instrument base 5, performing a preliminary limit on the instrument base 5. Then, by respectively rotating the connection columns 76 on both sides, the connection columns 76 drive the second threaded rods 75 to rotate, further driving the pressing blocks 73 to slide on the moving blocks 72, realizing the limit fixation of the pressing blocks 73 on the instrument base 5. Then, by rotating the rotation knob 65, the rotation knob 65 drives the first threaded rod 64 to rotate. The first threaded rod 64 drives the limit displacement plate 62 to contact the instrument base 5, realizing the re-fixation of the instrument base 5, ensuring the stability of the instrument base 5, and further improving the stability of the aerial photography instrument 4.

[0024] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand 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.
