[0004] In order to reduce dust from falling and accumulating on the camera, the present application provides a drone aerial survey device and a measurement method.

[0005] In the first aspect, the present application provides an unmanned aerial survey device that adopts the following technical solution:

[0006] A drone aerial survey device comprises a body and a bracket for supporting the body, a dust shielding assembly is arranged at one horizontal end of the body, a moving rod is rotatably connected to the body, an end of the moving rod away from the body is connected to the dust shielding assembly, a locking assembly for positioning the dust shielding assembly is arranged on the moving rod, and a counterweight is arranged at one end of the body away from the dust shielding assembly.

[0007] By adopting the above technical solution, the counterweight block is used to balance the weight of the dust shield assembly at one end of the body. At the same time, when the drone is stored, the moving rod drives the dust shield assembly to move to the top of the camera, and the locking assembly locks the dust shield assembly to fix the position of the dust shield assembly. The dust shield assembly shields the camera from dust. At this time, the dust in the air descends under the action of gravity and is accumulated on the dust shield assembly, thereby reducing the falling of dust and the accumulation of dust on the camera.

[0008] Optionally, the dust shielding assembly includes a center rod, a support member and two elastic sheets. The center rod is connected to the locking assembly, the two elastic sheets are connected on both sides of the center rod in a radial direction, and the two elastic sheets are elastically rolled up on both sides of the center rod. The support member is installed on the center rod, and the support member can spread out and support the elastic sheets.

[0009] By adopting the above technical solution, when the elastic sheet needs to be opened, the support member will open the elastic sheet, and at the same time the support member will support the expansion of the elastic sheet, so that the elastic sheet is in a continuously expanded state. At this time, the expanded elastic sheet can shield the camera from dust.

[0010] Optionally, the support member includes a support rod and a paddle, a support hole is provided on the center rod, the support hole is horizontally penetrated through the center rod, the support rod is rotatably connected to the inner wall of the support hole, and the paddle is used to control the rotation of the support rod.

[0011] By adopting the above technical solution, the support rod is rotated by using the paddle, and the end wall of the support rod continuously contacts the elastic sheet to unfold the elastic sheet; at the same time, the positioning member positions the position of the support rod so that the support rod can stably support the elastic sheet.

[0012] Optionally, a positioning piece is provided between the elastic sheet and the support rod, the positioning piece includes a positioning rod and a rubber sleeve, the positioning rod is connected to the end of the elastic sheet away from the center rod, a positioning groove is opened at one end of the positioning rod, the rubber sleeve is sleeved on the end of the support rod away from the center rod, and the end of the support rod with the rubber sleeve is interference-inserted into the positioning groove.

[0014] Optionally, both ends of the support rod are provided with arc surfaces.

[0015] By adopting the above technical solution, the setting of the arc surface reduces the contact between the support rod and the elastic sheet, so that when the elastic sheet is opened, the support rod with the arc surface smoothly opens the elastic sheet, reducing the wear of the elastic sheet by sharp edges.

[0016] Optionally, one end of the moving rod away from the body is connected to one end of the center rod away from the body, and the locking assembly is arranged between the moving rod and the center rod to lock the positions of the moving rod and the center rod.

[0017] By adopting the above technical solution, the moving rod can smoothly drive the center rod to move, and the locking assembly relatively fixes the positions of the moving rod, the center rod and the body. At the same time, a triangle is formed between the moving rod, the center rod and the locking assembly, and the triangle structure is relatively stable.

[0018] Optionally, the locking assembly includes a sliding dovetail block, a limit plate and a locking arc block, the end of the moving rod away from the body is connected to the sliding dovetail block, the end of the center rod away from the body is provided with a dovetail groove, the sliding dovetail block is inserted in the dovetail groove and slides in the extension groove along the length direction of the center rod; the end of the moving rod close to the body is rotatably connected to a locking cylinder, the piston rod of the locking cylinder is connected to the locking arc block, the locking arc block is in contact with the side wall of the center rod, the limit plate is connected to the side wall of the end of the center rod close to the body, and the body is provided with a locking groove for the center rod to be inserted.

[0019] By adopting the above technical solution, the center rod is rotated to align the center rod with the locking groove, and the center rod is inserted into the locking groove. At this time, the sliding dovetail block slides in the dovetail groove. When the sliding dovetail block is in contact with the inner wall of the dovetail groove, the center rod abuts against the bottom of the locking groove; the locking cylinder is started, and the piston rod of the locking cylinder extends to make the end wall of the locking arc block in contact with the center rod. At this time, the limit plate is located between the locking arc block and the body. The restriction of the locking arc block makes it difficult for the limit plate to move, thereby limiting the position of the center rod.

[0020] Optionally, a reinforcement rod is provided on the bracket, and a reinforcement hole for inserting the center rod is opened on the reinforcement rod.

[0021] By adopting the above technical solution, when the UAV needs to be used, the operator uses the paddle to rotate the support rod again, and the support rod disengages from the positioning slot, and continues to rotate so that the support rod is completely retracted into the support hole. At this time, the elastic sheet rewinds under the elastic action; the locking cylinder is started, and the piston rod of the locking cylinder retracts into the cylinder body. At this time, the locking arc block is away from the center rod, and the restriction on the limit plate is released, and the center rod moves and smoothly disengages from the locking slot; the center rod is rotated again to align the center rod with the reinforcement hole, and the above actions are repeated to fix the position of the center rod.

[0022] In the second aspect, the present application provides a measurement method using a drone aerial survey device, which adopts the following technical solution:

[0028] By adopting the above technical solution, the setting of the dust shielding component reduces the dust falling and accumulating on the camera; at the same time, the cooperation of the moving rod and the locking component allows the dust shielding component to be moved at any time according to actual conditions, thereby reducing the influence of the dust shielding component on the camera's recording when the drone is in use.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The counterweight is used to balance the weight of the dust shield assembly at one end of the drone. When the drone is stored, the moving rod drives the dust shield assembly to move above the camera, and the locking assembly locks the dust shield assembly to fix the position of the dust shield assembly. The dust shield assembly shields the camera from dust. At this time, the dust in the air falls under the action of gravity and accumulates on the dust shield assembly, reducing dust from falling and accumulating on the camera.

[0031] 2.

Start the locking cylinder, and the piston rod of the locking cylinder extends to make the end wall of the locking arc block in contact with the center rod. At this time, the limit plate is located between the locking arc block and the body. The restriction of the locking arc block makes it difficult for the limit plate to move, thereby limiting the position of the center rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Reference Figure 2 A positioning slot 3411 is provided at one end of the positioning rod 341 close to the supporting hole 3211, and the positioning slot 3411 is communicated with the other two sides of the positioning rod 341 in the horizontal direction; rubber sleeves 342 are sleeved on both ends of the support rod 321, and the support rod 321 rotates, and finally the part of the support rod 321 sleeved with the rubber sleeve 342 is smoothly inserted into the positioning slot 3411, and at this time, the rubber sleeve 342 is tightly pressed against the inner wall of the positioning slot 3411.

[0046] Reference Figure 2 The locking assembly 5 includes a sliding dovetail block 51, and the end of the moving rod 4 away from the body 1 is connected to the sliding dovetail block 51. The bottom wall of the center rod 31 is provided with a dovetail groove 311, and the dovetail groove 311 is located at the end of the center rod 31 away from the body 1.

The sliding dovetail block 51 is preset in the dovetail groove 311, and the sliding dovetail block 51 is slidably arranged along the length direction of the dovetail groove 311.

[0047] Reference Figure 2 and Figure 3A locking cylinder 41 is provided at one end of the moving rod 4 close to the body 1, and the cylinder body of the locking cylinder 41 is rotatably connected to the moving rod 4 through a swivel. A locking arc block 53 is fixed on the piston rod of the locking cylinder 41 by welding, and the end wall of the locking arc block 53 away from the locking cylinder 41 can be in contact with the side wall of the center rod 31; a limiting plate 52 is provided at one end of the center rod 31 close to the body 1, and the limiting plate 52 is fixed to the side wall of the center rod 31 by welding. At this time, a locking groove 11 is opened on the side wall of the body 1 close to the center rod 31, and the end of the center rod 31 close to the body 1 can be inserted into the locking groove 11, and the depth of the locking groove 11 is less than the length from the limiting plate 52 to the end of the center rod 31.

[0048] Reference Figure 1 A reinforcement rod 21 is provided on the bracket 2, and the reinforcement rod 21 is horizontally arranged. A reinforcement hole 211 is opened on the reinforcement rod 21. When the center rod 31 rotates around the rotating rod to the same horizontal plane as the reinforcement rod 21, the end of the center rod 31 close to the body 1 can be inserted into the reinforcement rod 21.

[0049] The implementation principle of a drone aerial survey device in an embodiment of the present application is as follows: when the drone is stored, first rotate the center rod 31 so that the center rod 31 is aligned with the locking groove 11, and the center rod 31 is inserted into the locking groove 11. At this time, the sliding dovetail block 51 slides in the dovetail groove 311. When the sliding dovetail block 51 is in contact with the inner wall of the dovetail groove 311, the center rod 31 abuts against the bottom of the locking groove 11; start the locking cylinder 41, and the piston rod of the locking cylinder 41 extends out, so that the end wall of the locking arc block 53 is in contact with the center rod 31. At this time, the limit plate 52 is located between the locking arc block 53 and the body 1. The restriction of the locking arc block 53 makes it difficult for the limit plate 52 to move, thereby limiting the position of the center rod 31.

[0050] The support rod 321 is then rotated by using the paddle 322, and the end wall of the support rod 321 continuously contacts the elastic sheet 33 to unfold the elastic sheet 33, and finally the part of the support rod 321 covered with the rubber sleeve 342 is smoothly inserted into the positioning slot 3411, and the rubber sleeve 342 is now tightly pressed against the inner wall of the positioning slot 3411; the support rod 321 firmly supports the unfolding of the elastic sheet 33, and the unfolded elastic sheet 33 protects the camera underneath it, and dust in the air falls on the top wall of the elastic sheet 33 under the action of gravity, thereby reducing the falling of dust and the accumulation of dust on the camera.

[0051] When the drone needs to be used, the operator uses the paddle 322 to rotate the support rod 321 again, and the support rod 321 escapes from the positioning slot 3411 and continues to rotate until the support rod 321 is completely received in the support hole 3211. At this time, the elastic sheet 33 rewinds under the elastic action.

[0052] Start the locking cylinder 41, and the piston rod of the locking cylinder 41 retracts into the cylinder body. At this time, the locking arc block 53 is away from the center rod 31, and the restriction on the limit plate 52 is released, and the center rod 31 moves and smoothly escapes from the locking groove 11; rotate the center rod 31 again to align the center rod 31 with the reinforcement hole 211, and repeat the above actions to fix the position of the center rod 31.

[0053] The present application also provides a measurement method using a drone aerial survey device, comprising the following steps:

[0054] After taking out the drone, the operator uses the paddle 322 to rotate the support rod 321 again, and the support rod 321 is disengaged from the positioning slot 3411, and continues to rotate until the support rod 321 is completely received in the support hole 3211. At this time, the elastic sheet 33 is rolled back under the elastic action.

[0055] Start the locking cylinder 41, and the piston rod of the locking cylinder 41 retracts into the cylinder body. At this time, the locking arc block 53 is away from the center rod 31, and the restriction on the limit plate 52 is released, and the center rod 31 moves and smoothly escapes from the locking groove 11; rotate the center rod 31 again, align the center rod 31 with the reinforcement hole 211, and insert the end of the center rod 31 close to the body 1 into the center rod 31. The locking cylinder 41 presses the locking arc block 53 against the center rod 31, and the limit plate 52 is located between the locking arc block 53 and the reinforcement rod 21. At this time, the position of the center rod 31 is fixed, exposing the camera.

[0056] The drone starts, flies according to the preset route, and turns on the camera for measurement.

[0057] Collect aerial survey data, record and analyze them.

[0058] When the drone is finished using and needs to be stored, first rotate the center rod 31 to align the center rod 31 with the locking groove 11, and the center rod 31 is inserted into the locking groove 11. At this time, the sliding dovetail block 51 slides in the dovetail groove 311. When the sliding dovetail block 51 is in contact with the inner wall of the dovetail groove 311, the center rod 31 abuts against the bottom of the locking groove 11; start the locking cylinder 41, and the piston rod of the locking cylinder 41 extends, so that the end wall of the locking arc block 53 is in contact with the center rod 31. At this time, the limit plate 52 is located between the locking arc block 53 and the body 1. The restriction of the locking arc block 53 makes it difficult for the limit plate 52 to move, thereby limiting the position of the center rod 31.

[0059] The support rod 321 is then rotated by using the paddle 322, and the end wall of the support rod 321 continuously contacts the elastic sheet 33 to unfold the elastic sheet 33, and finally the part of the support rod 321 covered with the rubber sleeve 342 is smoothly inserted into the positioning slot 3411, and the rubber sleeve 342 is now tightly pressed against the inner wall of the positioning slot 3411; the support rod 321 firmly supports the unfolding of the elastic sheet 33, and the unfolded elastic sheet 33 protects the camera underneath it, and dust in the air falls on the top wall of the elastic sheet 33 under the action of gravity, thereby reducing the falling of dust and the accumulation of dust on the camera.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
