The clamping plate 7 is connected to the vertical plate 5 through a second spring 8. A bottom plate 9 is detachably connected to the bottom of the vertical plate 5 for installing surveying instruments of different sizes.

[0033] A positioning mechanism 3 is provided on one side of the mounting plate 2 for positioning the movable block 4;

[0034] The positioning mechanism 3 includes a baffle 31, which is slidably connected to one side of the mounting plate 2, and a baffle 32 is fixedly connected to the back of the mounting plate 2, so as to prevent the movable block 4 from moving out of the slot at will, thereby preventing the surveying instrument from falling off during the flight of the UAV.

[0035] Reference Figure 2 and Figure 3 A plurality of openings are formed on one side of the vertical plate 5, and the slide rod 6 is slidably connected in the opening. The other end of the slide rod 6 is fixedly connected to a limit plate, and the size of the limit plate is larger than the size of the inner side of the opening to prevent the slide rod 6 from detaching from the vertical plate 5.

[0036] Reference Figure 2 and Figure 3 A slide groove is provided on one side of the mounting plate 2, a slider 33 is slidably connected in the slide groove, and the blocking bar 31 is located on one side of the slider 33, so that the blocking bar 31 can move vertically.

[0037] Reference Figure 2 and Figure 3 The cross section of the stop bar 31 is L-shaped, so that when the movable block 4 is located between the stop bar 31 and the baffle 32, it cannot move out of the slot.

[0038] Reference Figure 2 and Figure 3 A handle is fixedly connected to the front of the baffle bar 31, so that the staff can pull the handle to drive the baffle bar 31 to move upward.

[0039] Reference Figure 3 and Figure 4 A vertical rod 34 is fixedly connected in the slide groove, and the slider 33 is slidably sleeved on the outside of the vertical rod 34, so as to prevent the slider 33 from escaping from the slide groove.

[0040] Reference Figure 4 A first spring 35 is fixedly connected to the top of the slider 33, the top of the first spring 35 is fixedly connected to the top of the inner wall of the slide groove, and the first spring 35 is sleeved on the outside of the vertical rod 34, so as to prevent the slider 33 from moving vertically at will.

[0041] Reference Figure 4 A first threaded rod 36 is threadedly connected to one side of the blocking bar 31 , and a first threaded groove for matching with the first threaded rod 36 is provided on one side of the sliding block 33 , so that the staff can disassemble and assemble the blocking bar 31 conveniently.

[0042] Reference Figure 4 The cross-sections of the movable block 4 and the slot are both T-shaped, thereby preventing the movable block 4 from moving vertically.

[0043] Reference Figure 2 and Figure 3 Suction cups 12 are fixedly connected to both sides of the top of the bottom plate 9 for adsorbing the bottom of the surveying instrument to further ensure the stability of the surveying instrument.

[0044] Reference Figure 2 and Figure 3 Two groups of second thread grooves are symmetrically opened on one side of the vertical plate 5, and the number of each group of second thread grooves is multiple. Side plates 10 are fixedly connected to both sides of the top of the bottom plate 9. A second threaded rod 11 is threadedly connected to one side of the side plate 10. The second threaded rod 11 is threadedly connected to the second thread groove, so as to facilitate the vertical adjustment of the position of the bottom plate 9.

[0045] The implementation principle of the surveying instrument fixing device for unmanned aerial vehicle surveying in the embodiment of the present application is as follows: when the staff needs to install the surveying instrument, the bottom of the surveying instrument can be adsorbed on the top of the suction cup 12, and then the vertical plate 5 is connected to the side plate 10, so that the surveying instrument is clamped by the sliding rod 6, the second spring 8 and the clamping plate 7, and then the staff can pull the baffle bar 31 to move upward, and the upward movement of the baffle bar 31 can drive the sliding block 33 to move upward and squeeze the first spring 35, so that the baffle bar 31 moves to a position where it does not block the slot, and then the staff can insert the movable block 4 into the slot and push the movable block 4 to move along the direction of the slot until the movable block 4 abuts against the baffle plate 32, and then the staff can loosen the baffle bar 31, so that the baffle bar 31 moves downward to a position that blocks the slot, and because the cross-sections of the slot and the movable block 4 are both T-shaped, the movable block 4 will not move out of the slot at will, thereby facilitating the guarantee that the surveying instrument will not fall off.

[0046] The embodiment of the present application provides a surveying instrument fixing device for unmanned aerial vehicle surveying and mapping. By setting a positioning mechanism 3, the movable block 4 can be positioned during the flight surveying and mapping of the unmanned aerial vehicle, so that the movable block 4 will not be separated from the groove, thereby preventing the vertical plate 5, the bottom plate 9 and the surveying instrument from falling, thereby improving the protection performance of the surveying instrument.
