Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping equipment technology, and more specifically, to a surveying and mapping device for natural resource surveying and collection. Background Technology

[0002] Natural resources refer to substances in nature that humans can directly obtain for production and daily life. Surveying drones are devices assembled using drones and surveying equipment, used to detect and map natural environments that are difficult for humans to measure, reducing the risks to workers and improving surveying efficiency.

[0003] Patent document CN221585777U discloses a remote sensing mapping drone, including a drone body, a mounting box, a motor, a ball screw nut, a connecting plate, a window, a rotating rod, landing gear legs, and a protective box. The drone body is equipped with the mounting box, which holds the motor. A lead screw is mounted on the motor's drive shaft, and a ball screw is threaded onto the lead screw. A connecting plate is mounted on the ball screw, and a gear plate is mounted on the connecting plate's port. A rotating rod is rotatably mounted at the window, and a gear is mounted on the rotating rod, meshing with the gear plate. Landing gear legs are mounted on the rotating rod. This invention allows the landing gear to be retracted during drone operation, preventing it from obstructing the surveying instrument's imaging. This improves the usability and imaging effect of the remote sensing mapping drone, and protects the surveying equipment, preventing damage to the surveying instrument due to a lack of protective structure during drone landing. However, existing surveying drones still require motors to open and close the protective box. Using motors increases equipment costs and adds an extra operation. If the motors are not controlled to close the protective box when the drone is landing, the landing legs will not be deployed, causing the surveying instrument to touch the ground and potentially damaging it. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a surveying and mapping device for natural resource investigation and collection, which can open and close the protective box solely through gravity and contact with the ground, reducing operational steps, lowering the probability of operational errors, and protecting the surveying instrument.

[0005] A surveying and mapping device for natural resource investigation and collection includes a drone body and a surveying instrument mounted on the lower end face of the drone body. Two mounting brackets are fixedly connected to the lower end face of the drone body. A rotating rod is rotatably connected to the mounting bracket. A connecting block is fixedly connected to the rotating rod. A protective box is fixedly connected to the free end of the connecting block. Gears are fixedly connected to both ends of the rotating rod. A fixing block is fixedly connected to the side of the two mounting brackets that are close to each other. A connecting plate slides on the fixing block. A toothed plate that meshes with the gear is fixedly connected to the side of the connecting plate that is close to the gear. The lower end of each connecting plate is fixedly connected to a counterweight frame. The mass of the counterweight frame is much greater than the sum of the masses of the two protective boxes.

[0006] Furthermore, the mounting bracket is an inverted U-shape.

[0007] Furthermore, the lower end face of the counterweight frame is fixedly connected to a support leg.

[0008] Furthermore, the protective box is made of rigid sponge.

[0009] Furthermore, the counterweight frame, the connecting plate, and the support legs are all made of transparent acrylic material.

[0010] Furthermore, a limiting groove is provided in the fixing block, and the upper end of the connecting plate is adapted to the limiting groove and slides within the limiting groove.

[0011] Furthermore, the cross-section of the limiting groove is T-shaped.

[0012] Furthermore, a first locking block is fixedly connected to the side wall of the fixing block, and a second locking block is fixedly connected to both sides of the toothed plate.

[0013] Furthermore, a rubber block is fixed to the top wall inside the limiting groove.

[0014] Furthermore, the protective box and the connecting block are bonded together with adhesive, and the counterweight frame, the connecting plate and the support leg are bonded together with adhesive.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, during the takeoff of the UAV, the counterweight frame and connecting plate move downwards under the influence of gravity. The toothed plate meshes with the gear, and as the toothed plate moves downwards, the gear drives the rotating rod to rotate. The rotation of the two rotating rods causes the two protective boxes to rotate away from each other, exposing the surveying instrument located between the two protective boxes, thus enabling surveying operations. After the surveying operation is completed, during the descent of the UAV, the counterweight frame contacts the ground, causing the connecting plate to move upwards. Through the engagement of the toothed plate and gear, the two rotating rods rotate inwards, causing the two protective boxes to rotate closer to each other, enclosing the surveying instrument within the two protective boxes and closing the protective boxes. This allows the protective boxes to be opened and closed solely by gravity and contact with the ground, reducing manual operation steps, lowering the probability of operational errors, and protecting the surveying instrument.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific implementation examples:

[0026] like Figure 1-5 As shown, a surveying and mapping device for natural resource surveying and data collection includes a drone body 1. A surveying instrument 2 is mounted on the lower end of the drone body 1. Two parallel mounting frames 3 are fixedly connected to the lower end of the drone body 1. The mounting frames 3 are inverted U-shapes. A rotating rod 4 is rotatably connected through the mounting frame 3. A connecting block 5 is fixedly connected to the rotating rod 4. A protective box 6 is fixedly connected to the free end of the connecting block 5. Gears 7 are fixedly connected to both ends of the rotating rod 4. Two fixing blocks 8 are fixedly connected to the sides of the two mounting frames 3 that are close to each other. A connecting plate 9 slides on each fixing block 8. A toothed plate 10 is fixedly connected to the side of the connecting plate 9 that is close to the gear 7. The toothed surfaces of the toothed plate 10 face the adjacent gear 7. The adjacent toothed plates 10 and gears 7 mesh with each other. The lower end of each connecting plate 9 is fixedly connected to a counterweight frame 11. The mass of the counterweight frame 11 is much greater than the sum of the masses of the two protective boxes 6. During takeoff, the counterweight frame 11 and connecting plate 9 move downwards under the influence of gravity. The toothed plate 10 meshes with the gear 7, and as the toothed plate 10 moves downwards, the gear 7 drives the rotating rod 4 to rotate. The rotation of the two rotating rods 4 causes the two protective boxes 6 to rotate away from each other, exposing the surveying instrument 2 located between the two protective boxes 6, thus enabling surveying operations. After the surveying operation is completed, during the descent of the drone body 1, the counterweight frame 11 first contacts the ground, preventing the surveying instrument 2 from directly contacting the ground. After the counterweight frame 11 contacts the ground, the drone body 1 continues to descend, causing the connecting plate 9 to move upwards relative to the fixed block 8. Through the engagement of the toothed plate 10 and the gear 7, the two rotating rods 4 rotate inwards, causing the two protective boxes 6 to rotate closer to each other, enclosing the surveying instrument 2 within the two protective boxes 6, thus closing the protective boxes 6. This allows the protective boxes to be opened and closed solely by gravity and contact with the ground, reducing manual operation steps, lowering the probability of operational errors, and protecting the surveying instrument 2.

[0027] like Figure 1-5 As shown, a support leg 12 is fixedly connected to the lower end face of the counterweight frame 11. By setting the support leg 12, the overall height of the device is increased, and the height of the protective box 6 from the ground is also increased, which can better protect the surveying instrument 2.

[0028] like Figure 1-5 As shown, the protective box 6 is made of rigid sponge, and the protective box 6 is bonded to the connecting block 5 with glue. The counterweight frame 11, the connecting plate 9 and the support leg 12 are all made of transparent acrylic material, and the counterweight frame 11, the connecting plate 9 and the support leg 12 are bonded to each other with glue. The device does not require a motor to drive the opening and closing of the protective box 6, thus reducing the cost of the device.

[0029] like Figure 1-5As shown, a limiting groove 81 is provided in the fixed block 8. The cross-section of the limiting groove 81 is T-shaped. The upper end of the connecting plate 9 is adapted to the limiting groove 81 and slides in the limiting groove 81, so that the connecting plate 9 can slide on the fixed block 8.

[0030] like Figure 1-5 As shown, two first locking blocks 13 are fixedly connected to the side wall of the fixed block 8 on one side of the opening of the limiting slide groove 81. Two second locking blocks 14 are fixedly connected to both sides of the toothed plate 10. When the drone body 1 takes off and the two protective boxes 6 are fully opened, the second locking block 14 abuts against the upper surface of the first locking block 13 to prevent the connecting plate 9 from coming out of the limiting slide groove 81.

[0031] like Figure 1-5 As shown, a rubber block 15 is fixedly connected to the top wall inside the limiting slide groove 81. When the main body 1 of the drone lands, the outrigger 12 contacts the ground, causing the connecting plate 9 to slide in the limiting slide groove 81 until the upper end of the connecting plate 9 hits the rubber block 15 located in the limiting slide groove 81. The rubber block 15 can buffer part of the impact force of the connecting plate 9, making the device more stable when it lands on the ground.

[0032] The working principle of a surveying and mapping device for natural resource surveying and collection in this embodiment is as follows: During the takeoff of the UAV body 1, under the action of gravity, the counterweight frame 11 and the connecting plate 9 move downwards. The toothed plate 10 meshes with the gear 7, and the toothed plate 10 moves downwards, causing the gear 7 to drive the rotating rod 4 to rotate. The rotation of the two rotating rods 4 causes the two protective boxes 6 to rotate away from each other, exposing the surveying instrument 2 located between the two protective boxes 6, thus enabling surveying operations. After the surveying operation is completed, during the descent of the UAV body 1, after the counterweight frame 11 contacts the ground, the connecting plate 9 moves upwards, and through the engagement of the toothed plate 10 and the gear 7, the two rotating rods 4 rotate inwards, causing the two protective boxes 6 to rotate closer to each other, enclosing the surveying instrument 2 within the two protective boxes 6, thus closing the protective boxes 6. In this way, the protective boxes can be opened and closed only by gravity and contact with the ground, reducing manual operation steps, lowering the probability of operational errors, and protecting the surveying instrument 2.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
