DETAILED DESCRIPTION

[0020] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0021] like Figure 1-3 As shown, a UAV aerial geophysical survey hanging device includes a horizontal plate 1 and a base 2. The base 2 is fixedly connected to the bottom end of the horizontal plate 1. The two ends of the base 2 are respectively slidably connected with a first end limit assembly 3 and a second end limit assembly 4. The first end limit assembly 3 and the second end limit assembly 4 have the same structure. The first end limit assembly 3 includes an arc-shaped pressure plate 31 slidably connected to the bottom of the base 2. One end of the arc-shaped pressure plate 31 is fixedly connected to an end plate 32. One end of the arc-shaped pressure plate 31 is symmetrically provided with a connecting plate 34. The surface of the connecting plate 34 is provided with a clamping hole 35 and a slide groove 36. One end of the slide groove 36 is connected to the clamping hole 35. One end of the end plate 32 is symmetrically provided with a column 33. Both ends of the base 2 are symmetrically provided with grooves. The two column tubes 33 are respectively slidably connected to the inside of the two grooves at one end of the base 2. The bottom end of the base 2 is symmetrically provided with a locking assembly 5 for cooperating with the clamping hole 35. The four corners of the horizontal plate 1 are provided with mounting holes 11.

[0022] According to the above structure, during installation, screws are used to pass through the mounting holes 11 to fix the cross plate 1 on the bottom of the UAV wing. When installing the optically pumped magnetometer probe, the optically pumped magnetometer probe is placed inside the base 2, and then the two arc-shaped pressure plates 31 are slid to make the arc-shaped pressure plates 31 slide to the end of the optically pumped magnetometer probe, thereby clamping the end of the optically pumped magnetometer probe inside the base 2 to complete the hanging installation of the optically pumped magnetometer probe. The locking assembly 5 can lock the two arc-shaped pressure plates 31 to prevent the optically pumped magnetometer probe from falling off. The hanging installation operation of the optically pumped magnetometer probe is simple and easy to disassemble and assemble, thereby facilitating the maintenance and replacement of the optically pumped magnetometer probe.

[0023] like Figure 1 and 3As shown, the connecting plate 34 of the first end limit assembly 3 and the connecting plate 34 of the second end limit assembly 4 are staggered in the vertical direction, and a slot 37 is symmetrically provided at one end of the arc-shaped pressure plate 31 of the first end limit assembly 3, and one end of the two connecting plates 34 of the second end limit assembly 4 are respectively inserted into the inside of the two slots 37.

[0024] According to the above structure, when the two arc-shaped pressure plates 31 are slid, one end of the two connecting plates 34 of the second end limit assembly 4 is respectively inserted into the inside of the two slots 37 to improve the stability of the two connecting plates 34 of the second end limit assembly 4.

[0025] like Figure 3 and 5 As shown, the locking assembly 5 includes a concave cavity 51 arranged at the bottom end of the base 2, the interior of the concave cavity 51 is rotatably connected with a shaft cylinder 52, the bottom end of the shaft cylinder 52 is fixedly connected with a waist-shaped column head 53, the bottom end of the waist-shaped column head 53 is provided with a slot 54, the interior of the shaft cylinder 52 is fixedly connected with a torsion spring 55, one end of the torsion spring 55 is fixedly connected to one end of the concave cavity 51, the length of the waist-shaped column head 53 is equal to the diameter of the clamping hole 35, and the width of the waist-shaped column head 53 is equal to the width of the slide groove 36.

[0026] According to the above structure, when locking the arc pressure plate 31, the waist-shaped column head 53 is rotated by a screwdriver to make the waist-shaped column head 53 parallel to the slide groove 36. At this time, the arc pressure plate 31 is slid, and the waist-shaped column head 53 slides into the interior of the slide groove 36. When the waist-shaped column head 53 slides to the interior of the clamping hole 35, under the torsion of the torsion spring 55, the waist-shaped column head 53 is reversed and perpendicular to the slide groove 36, so that it is clamped in the interior of the clamping hole 35, and then the arc pressure plate 31 can be positioned. When disassembling, similarly, it is only necessary to rotate the waist-shaped column head 53 to make it parallel to the slide groove 36 to slide the arc pressure plate 31 away from the end of the optical pump magnetometer probe.

[0027] like Figure 3 and 4 As shown, a spring 38 is fixedly connected inside the column 33, and one end of the spring 38 is fixedly connected to one end of the corresponding groove.

[0028] According to the above structure and the setting of the spring 38, when the optical pumping magnetometer probe is disassembled, the waist-shaped column head 53 is twisted to make it parallel to the slide groove 36, and the arc pressure plate 31 can be pushed away from the end of the optical pumping magnetometer probe under the elastic force of the spring 38, so as to facilitate the disassembly of the optical pumping magnetometer probe.

[0029] like Figure 2 As shown, in order to reduce air resistance during use, one end of the second end limit assembly 4 is fixedly connected to an arc-shaped splitter plate 6.

[0030] The working principle of the utility model is as follows: during installation, screws are used to pass through the mounting holes 11 to fix the cross plate 1 on the bottom of the drone wing; when installing the optical pump magnetometer probe, the optical pump magnetometer probe is placed inside the base 2, and then the two arc-shaped pressure plates 31 are slid to make the arc-shaped pressure plates 31 slide to the end of the optical pump magnetometer probe, thereby clamping the end of the optical pump magnetometer probe inside the base 2 to complete the hanging installation of the optical pump magnetometer probe; the locking assembly 5 can lock the two arc-shaped pressure plates 31 to prevent the optical pump magnetometer probe from falling off; the hanging installation operation of the optical pump magnetometer probe is simple, easy to disassemble and assemble, and thus easy to maintain and replace the optical pump magnetometer probe; when sliding the two arc-shaped pressure plates 31, one end of the two connecting plates 34 of the second end limit assembly 4 is respectively plugged into the two slots 37, thereby increasing the two ends of the second end limit assembly 4 The stability of the connecting plate 34, when locking the arc pressure plate 31, the waist-shaped column head 53 is rotated by the screwdriver to make the waist-shaped column head 53 parallel to the sliding groove 36, at this time, the sliding arc pressure plate 31 is slid, and the waist-shaped column head 53 slides into the interior of the sliding groove 36. When the waist-shaped column head 53 slides to the inside of the clamping hole 35, under the torsion of the torsion spring 55, the waist-shaped column head 53 is reversed and perpendicular to the sliding groove 36, so that it is stuck in the interior of the clamping hole 35, and then the arc pressure plate 31 can be positioned. When disassembling, similarly, you only need to rotate the waist-shaped column head 53 to make it parallel to the sliding groove 36 to slide the arc pressure plate 31 away from the end of the optical pump magnetometer probe. The setting of the spring 38, when disassembling the optical pump magnetometer probe, twist the waist-shaped column head 53 to make it parallel to the sliding groove 36, and under the elastic force of the spring 38, the arc pressure plate 31 can be pushed away from the end of the optical pump magnetometer probe, which is convenient for disassembling the optical pump magnetometer probe.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
