Description

Technical Field

[0001] This utility model relates to the field of drone inspection technology, and in particular to a drone inspection and monitoring device. Background Technology

[0002] In the daily inspection of photovoltaic power plants, drones have become an indispensable inspection tool due to the vast area and high inspection difficulty. In order to fully cover the inspection area, drones need to take off and land frequently, which puts high demands on the adaptability and long-term durability of the airborne equipment. Among them, the monitoring devices (such as visible light cameras, infrared thermal imagers, etc.) are the core data acquisition units. They are not only expensive, but also composed of precision optical structures and electronic components, making them very sensitive to vibration and impact.

[0003] Currently, to achieve flexible adjustment of the monitoring perspective during flight, monitoring devices are usually connected to the drone fuselage via rotating mechanisms such as gimbals. While this type of structure can effectively solve the problem of freedom of movement, its buffering capacity is still insufficient when faced with the vertical impact generated when the drone lands. At the moment of landing, the impact force borne by the landing gear is transmitted through the main body of the fuselage to the gimbal mounting base, causing the entire rotating mechanism and the camera unit it supports to suffer severe instantaneous overload. Such impacts can easily lead to a decrease in the gimbal's adjustment accuracy, loosening of the locking structure, and in severe cases, direct damage to the fragile lens assembly and sensor components inside the monitoring device. Summary of the Invention

[0004] Therefore, the technical problem to be solved by this utility model is that existing drone monitoring devices are prone to failure when a drone makes an emergency landing.

[0005] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a drone inspection and monitoring device, which includes a drone body, a monitoring equipment body, and foot supports. The buffer unit includes a flip plate hinged to the foot support, a torsion spring sleeved on the outside of the flip plate's pivot, and a buffer member disposed between the flip plate and the foot support. A lever is connected to the flip plate; The lever rotates synchronously with the flip plate, thereby pushing the main body of the monitoring device to flip upward.

[0007] In a preferred embodiment of the UAV inspection and monitoring device of this utility model: the base plate has a hinge joint adapted to the flip plate; The flip plate includes a pivot that passes through the hinge of the base plate; The torsion spring is sleeved on the outside of the rotating shaft, and one end of the torsion spring abuts against the inner wall of the flip plate.

[0008] In a preferred embodiment of the UAV inspection and monitoring device of this utility model: the buffer includes a hinge seat connected to the base plate, a spring damping shock absorber hinged to the hinge seat, an end cap disposed at the end of the spring damping shock absorber away from the hinge seat, and a guide rod penetrating the end cap and extending to the side wall of the flip plate.

[0009] In a preferred embodiment of the UAV inspection and monitoring device of this utility model: the hinged seat is fixedly connected to the base plate; The side wall of the flip plate is provided with a guide groove; The guide rod is adapted to the guide groove.

[0010] In a preferred embodiment of the UAV inspection and monitoring device of this utility model: the flipping plate flips towards the base plate, the spring damping shock absorber flips along the axis of the hinge seat shaft hole, and the guide rod slides along the inner wall of the guide groove; The flip plate is parallel to the base plate, and the buffer is located inside the flip plate in a horizontal state.

[0011] In a preferred embodiment of the UAV inspection and monitoring device of this utility model: the torsion spring releases elastic potential energy to push the flipping plate to flip away from the base plate; The buffer is tilted and supported between the flip plate and the base plate as the flip plate flips.

[0012] In a preferred embodiment of the UAV inspection and monitoring device of this utility model: the lever is connected to a set of flip plates respectively, and the flip plates can rotate to drive the lever to contact the main body of the monitoring device.

[0013] In a preferred embodiment of the UAV inspection and monitoring device of this utility model: an electromagnetic buckle is installed inside the flip plate, and a U-shaped ring adapted to the electromagnetic buckle is installed on the surface of the base plate.

[0014] In a preferred embodiment of the UAV inspection and monitoring device of this utility model: the U-shaped ring cooperates with the electromagnetic buckle to fix the position between the flip plate and the base plate. The beneficial effects of this utility model are as follows: the buffer component will cause the lever to flip towards the side closer to the main body of the monitoring equipment when the drone lands, so that the lever can touch the main body of the monitoring equipment and lift it up a certain distance; and the buffer component is set between the flip plate and the foot support, which can effectively buffer the impact of the drone falling on the main body of the monitoring equipment and extend the service life of the main body of the monitoring equipment to a certain extent.

Detailed Implementation

[0017] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0019] Reference Figures 1-3 This embodiment provides a drone inspection and monitoring device, including a drone body 1, a monitoring equipment body 2, and a foot support 3. The buffer unit 4 includes a flip plate 41 hinged to the foot support 3, a torsion spring 42 sleeved on the outside of the rotating shaft of the flip plate 41, and a buffer member 43 disposed between the flip plate 41 and the foot support 3. The lever 5 is connected to the flip plate 41; The lever 5 rotates synchronously with the flip plate 41, which in turn pushes the main body 2 of the monitoring equipment upward.

[0020] It should be noted that the main body 2 of the monitoring equipment is mounted inside the main body 1 of the drone, and the main body 2 of the monitoring equipment is connected to the main body 1 of the drone through a gimbal structure to ensure that the main body 2 of the monitoring equipment can be adjusted relative to the main body 1 of the drone at multiple angles.

[0021] Furthermore, the foot support 3 is made of carbon fiber and is connected and fixed to the main body 1 of the drone by bolts. The buffer unit 4 is hinged to the foot support 3, and a torsion spring 42 is provided on the outside of the rotating shaft of the flip plate 41. The elastic potential energy released by the torsion spring 42 can push the flip plate 41 to flip to one side of the monitoring equipment main body 2. The flip plate 41 can drive the lever 5 to abut against the monitoring equipment main body 2, thereby pushing the monitoring equipment main body 2 to move upward, thus preventing the monitoring equipment main body 2 from hitting the ground protrusion when the drone lands.

[0022] When the drone lands, the limit of the flip plate 41 is released, and the torsion spring 42 releases its elasticity, which can push the flip plate 41 to drive the lever 5 to flip to the side of the monitoring equipment body 2. This causes the lever 5 to contact the monitoring equipment body 2 and push the monitoring equipment body 2 to flip upward, so as to ensure that the monitoring equipment body 2 can avoid contact with the ground protrusion when the drone lands. At the same time as the flip plate 41 flips and supports, the buffer 43 set between the flip plate 41 and the foot support 3 is also supported as the flip plate 41 flips. When the drone lands and vibrates, the buffer 43 can be used to dampen the monitoring equipment body 2, so as to reduce the damage to the monitoring equipment body 2 caused by the vibration when the drone lands.

[0023] Reference Figures 1-3 As an optional embodiment, the number of foot supports 3 is one set, and one set of foot supports 3 is symmetrically arranged at the bottom of the drone body 1; the foot support 3 includes a crossbeam 31 fixedly connected to the drone body 1, a vertical rod 32 arranged perpendicular to the side wall of the crossbeam 31, and a base plate 33 connected to the vertical rod 32; the base plate 33 is connected to the crossbeam 31 through the vertical rod 32.

[0024] It should be noted that there are two foot supports 3, which are symmetrically arranged on both sides of the bottom of the drone body 1; the crossbeam 31 is a plate structure with waist holes inside, the vertical rod 32 is set perpendicular to the crossbeam 31, and the vertical rod 32 is connected and fixed to the crossbeam 31 by bolts. The bottom of the base plate 33 is parallel to the ground, so that the base plate 33 can be close to the ground when the drone lands.

[0025] Furthermore, the base plate 33 has a hinge that is compatible with the flip plate 41. The flip plate 41 includes a pivot 411 that passes through the hinge of the base plate 33; The torsion spring 42 is sleeved on the outside of the rotating shaft 411, and one end of the torsion spring 42 abuts against the inner wall of the flip plate 41.

[0026] It should be noted that, in this embodiment, the base plate 33 has a hinge that cooperates with the flip plate 41, and the end of the flip plate 41 connected to the base plate 33 is provided with a rotating shaft 411, and the flip plate 41 can be flipped around the axis of the rotating shaft 411. Furthermore, the buffer 43 includes a hinge seat 431 connected to the base plate 33, a spring damping shock absorber 432 hinged to the hinge seat 431, an end cap 433 disposed at the end of the spring damping shock absorber 432 away from the hinge seat 431, and a guide rod 434 penetrating the end cap 433 and extending to the side wall of the flip plate 41.

[0027] It should be noted that the hinge seat 431 is fixedly connected to the base plate 33, and the spring damping shock absorber 432 is hinged to the hinge seat 431, which means that the spring damping shock absorber 432 can rotate relative to the base plate 33.

[0028] Furthermore, the hinge seat 431 is fixedly connected to the base plate 33; The side wall of the flip plate 41 is provided with a guide groove 412; The guide rod 434 is adapted to the guide groove 412.

[0029] It should be noted that the guide rod 434 passes through the side wall of the flip plate 41 and extends to its outer side. The guide rod 434 cooperates with the guide groove 412. When the flip plate 41 flips, it can drive the guide rod 434 to slide along the internal trajectory of the guide groove 412, thereby enabling the hinge seat 431 to be supported between the flip plate 41 and the base plate 33.

[0030] Furthermore, the flip plate 41 flips towards the base plate 33, the spring damping shock absorber 432 flips along the axis of the hinge seat 431 shaft hole, and the guide rod 434 slides along the inner wall of the guide groove 412. The flip plate 41 is parallel to the base plate 33, and the buffer 43 is located inside the flip plate 41 in a horizontal state.

[0031] It should be noted that, under normal circumstances, in order to further reduce the size of the drone, the flip plate 41 is set parallel to the base plate 33; the operator can push the flip plate 41 downward to flip it, so that the flip plate 41 is parallel to the surface of the base plate 33. While the flip plate 41 is flipped downward, it can squeeze the guide rod 434 to slide along the internal trajectory of the guide groove 412; the movement of the guide rod 434 can drive the other end of the spring damping shock absorber 432 to bend along the hinge position of the hinge seat 431, and then make the spring damping shock absorber 432 parallel to the flip plate 41 and the base plate 33.

[0032] Furthermore, the torsion spring 42 releases elastic potential energy to push the flipping plate 41 to flip away from the bottom plate 33. The buffer 43 tilts and is supported between the flip plate 41 and the base plate 33 as the flip plate 41 flips.

[0033] It should be noted that by releasing the limiting position between the flip plate 41 and the base plate 33, the torsion spring 42 releases its elastic potential energy, which can push the flip plate 41 to move away from the base plate 33. While the flip plate 41 flips, it drives the end of the guide rod 434 to move, so that the spring damping shock absorber 432 is positioned between the flip plate 41 and the base plate 33 and supported. When the lever 5 comes into contact with the main body 2 of the monitoring equipment, the impact transmitted from the drone to the main body 2 of the monitoring equipment can be transmitted to the flip plate 41 through the lever 5, and then the flip plate 41 can be pushed to flip downward. The downward flipping of the flip plate 41 will compress the spring damping shock absorber 432, which can effectively buffer the main body 2 of the monitoring equipment.

[0034] Reference Figure 3 In one embodiment provided in this application, an electromagnetic buckle 61 is installed inside the flip plate 41, and a U-shaped ring 62 adapted to the electromagnetic buckle 61 is installed on the surface of the base plate 33.

[0035] It should be noted that the electromagnetic buckle 61 is fixed inside the flip plate 41 by screws, and the opening and closing state of the electromagnetic buckle 61 can be controlled by a remote control handle.

[0036] When it is necessary to ensure that the flip plate 41 and the base plate 33 remain horizontal, the U-shaped ring 62 and the electromagnetic buckle 61 cooperate to fix the position between the flip plate 41 and the base plate 33, so as to ensure that the flip plate 41 is parallel to the base plate 33.

[0037] When the inspection personnel operate the electromagnetic buckle 61 to release the limit on the U-shaped ring 62, the torsion spring 42 releases elastic potential energy, which can drive the flip plate 41 to flip along the axis of the rotating shaft 411. The flip plate 41 flipping can then push the lever 5 to contact the main body 2 of the monitoring equipment.

[0038] Specifically, the U-shaped ring 62 is fixed to the surface of the base plate 33 by screws. When it is necessary to fix the position between the flip plate 41 and the base plate 33, pressing down the flip plate 41 can drive the electromagnetic buckle 61 to move towards the U-shaped ring 62, and then the U-shaped ring 62 is inserted into the electromagnetic buckle 61. The buckle inside the electromagnetic buckle 61 is used to limit the position of the U-shaped ring 62, thereby limiting the position between the flip plate 41 and the base plate 33.

[0039] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.

[0040] Importantly, the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
