[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0022] Reference Figure 1-5 As shown, an unmanned aerial vehicle surveying and mapping device for urban and rural terrain surveying and mapping comprises a flying machine body 1, a plurality of wing rods 2 surrounding and fixed to the outer periphery of the flying machine body 1, and a rotor 3 installed at the end of the wing rod 2, a surveying instrument 5 for measuring terrain is installed at the center of the bottom of the flying machine body 1, and landing gears 4 are arranged on both sides of the bottom of the flying machine body 1;
[0023] When in use, the flying machine body 1 is placed on the bottom surface as a whole using the landing gear 4 in advance, and then the flying machine body 1 is driven to make the rotor 3 rotate rapidly. The flying machine body 1 can be affected by the airflow and carry the surveying instrument 5 to rise and fly to the area to be surveyed, so that the surveying instrument 5 can perform terrain mapping in the air.
[0024] However, in practice, the surveying instrument 5 is mostly installed at the bottom of the UAV, and when the drone body 1 is stopped, its rotor 3 is very likely to raise a lot of dust on the ground, causing the lens of the surveying instrument 5 to be covered with a lot of dust, which seriously affects the use effect of the surveying instrument 5;
[0025] In view of this, refer to Figure 2-4 As shown, it is worth noting that it also includes a protection mechanism for improving the use effect of the surveying and mapping instrument 5;
[0026] The protection mechanism includes a blocking seat 6 slidably arranged on one side of the surveying instrument 5 and a fixing plate 7 vertically arranged on the other side of the surveying instrument 5 and fixed to the bottom surface of the flying machine body 1. A push-pull component for moving the blocking seat 6 is arranged on the side of the blocking seat 6 away from the fixing plate 7, and guide components for limiting the movement estimation of the blocking seat 6 are arranged on both sides of the fixing plate 7.
[0027] By setting the protection mechanism, when the flying machine body 1 stops, the push-pull components in the protection mechanism can act on the blocking seat 6 to quickly slide toward the side of the fixed plate 7 until it fits with the fixed plate 7. In this way, the two can cooperate to effectively form a protective shell from the outside of the surveying and mapping instrument 5, provide protection for the surveying and mapping instrument 5, and prevent the dust generated during the stopping process from covering the lens of the surveying and mapping instrument 5, thereby affecting the use effect of the surveying and mapping instrument 5.
[0028] Further, refer to Figure 3 and Figure 5 As shown, it is worth noting that the push-pull component includes a fixed cylinder 8 with a cavity inside and transversely fixed on the bottom surface of the flying machine body 1, a slide plate 9 slidably arranged inside the fixed cylinder 8, and a slide rod 10 vertically fixed on one side of the slide plate 9. The end of the slide rod 10 passes through the fixed cylinder 8 and is fixedly connected to the barrier seat 6. An electromagnet 12 is installed on the inner wall of the innermost side of the fixed cylinder 8, and a magnetic block 13 matching the electromagnet 12 is fixedly embedded on the other side of the slide plate 9.
[0029] A compression spring 11 is sleeved on the rod body of the slide rod 10 located inside the fixed tube 8, one end of the compression spring 11 is fixedly connected to the slide plate 9, and the other end of the compression spring 11 is fixedly connected to the inner wall of the fixed tube 8;
[0030] When the flying machine body 1 is stopped, the electromagnet 12 is remotely started in advance, so that the electromagnet 12 exerts a strong thrust on the magnetic block 13 and the slide plate 9 as a whole, so that the slide plate 9 and the slide rod 10 are forced to push the shielding seat 6 to slide toward the fixed plate 7 until the fixed plate 7 fits with the shielding seat 6, and the two cooperate to implement sealing protection for the surveying instrument 5;
[0031] During this process, the slide 9 can compress the compression spring 11 and deform it. When the compression spring 11 is away from the ground, the electromagnet 12 is turned off by remote control, and the repulsive force between the electromagnet 12 and the magnetic block 13 disappears. The slide 9 can then carry the slide rod 10 and the barrier seat 6 as a whole to quickly reset under the elastic force of the compression spring 11, thereby quickly exposing the surveying instrument 5 to the outside, thereby facilitating the surveying instrument 5 to survey the terrain.
[0032] Further, refer to Figure 2 As shown, it is worth noting that the guide component includes a fixing plate 14 vertically fixed to the side wall of the fixing plate 7 and a fixing rod 15 fixed to the fixing plate 14 in a T-shape, and a sliding sleeve 16 fixed to the side wall of the blocking seat 6 is slidably provided on the rod body of the fixing rod 15;
[0033] When the shielding seat 6 slides, the sliding sleeve 16 can be displaced synchronously with the rod body of the fixed rod 15. In this way, the two cooperate to limit the moving trajectory of the shielding seat 6 and ensure the stability of the shielding seat 6 when it moves.
[0034] Further, refer to Figure 3 and Figure 4As shown, it is worth noting that a mounting groove is provided at the bottom of the barrier seat 6, and a cleaning wiper plate 17 is detachably provided in the mounting groove;
[0035] By setting the cleaning wiper 17, during the sliding process of the shielding seat 6, the cleaning wiper 17 can simultaneously pass through the lens of the surveying instrument 5, and then wipe and clean the lens of the surveying instrument 5, remove dust and impurities on the lens of the surveying instrument 5, and ensure the accuracy of the surveying instrument 5 during surveying.
[0036] Further, refer to Figure 4 As shown, it is worth noting that a contraction groove 18 connected to the mounting groove is transversely arranged in the inner wall of the shielding seat 6, a positioning rod 19 is slidably arranged in the contraction groove 18, and a fixed channel adapted to the positioning rod 19 is opened on the side wall of the cleaning wipe plate 17, one end of the positioning rod 19 is inserted into the fixed channel, and a return spring 20 is fixed between the other end of the positioning rod 19 and the innermost inner wall of the contraction groove 18;
[0037] A movable seam connected to the shrinkage groove 18 is provided on the bottom surface of the shielding seat 6, and a push-pull block 21 fixedly connected to the positioning rod 19 is slidably arranged in the movable seam;
[0038] When a large amount of dust and impurities adhere to the surface of the cleaning wipe plate 17 after long-term use, affecting the cleaning effect, the person only needs to pull the push-pull block 21, and the positioning rod 19 can be forced to shrink toward the inside of the shrinkage groove 18 and compress the return spring 20 to deform until the positioning rod 19 withdraws from the fixed channel, thereby releasing the fixing effect of the cleaning wipe plate 17, thereby facilitating the removal and replacement of the cleaning wipe plate 17.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
