Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicle monitoring, and in particular, relates to a subsidence area unmanned aerial vehicle monitoring device. Background Art

[0002] After mining, the original stress balance of the overlying rock strata in the goaf is destroyed, and movement and deformation such as falling, breaking, and bending occur in sequence, eventually involving the surface, thus forming a collapse in the mining area. Mining collapse not only has an irreversible adverse impact on the natural environment, but also poses a great hidden danger to residents in the mining area. The biggest manifestation of mining collapse is the appearance of cracks on the surface. With the increasing application of drones, some monitoring of mineral collapse areas also uses this equipment, but drones also have certain defects in monitoring.

[0003] For example, the announcement number CN221438405U discloses an unmanned aerial vehicle ecological remote sensing monitoring device, which includes an unmanned aerial vehicle device and a monitoring device. The unmanned aerial vehicle device is composed of a supporting base, a buffer seat, a mounting bracket, a mounting seat, a flight bracket, a rotating blade, a protective tube, a control panel, a battery, and a docking port. The mounting seat of the unmanned aerial vehicle device is provided with a monitoring device, which is composed of a rotating adjustment motor, a rotating bracket, a rotating shaft, an angle adjustment motor, a telescopic electric push rod, and a monitoring lens. Since the utility model is provided with a monitoring device, the device is provided with a rotating adjustment motor, an angle adjustment motor, and a telescopic electric push rod, so that the monitoring lens of the monitoring device has a greater degree of freedom, thereby expanding the monitoring field of the monitoring lens and improving the information collection speed and accuracy of the remote sensing monitoring equipment.

[0004] When existing UAV monitoring equipment performs high-altitude monitoring operations, it is easy for the position and angle to be uncertainly offset due to the strong wind force at high altitudes and the turbulent wind generated during collapse. The single use of mechanical motors for angle control is difficult to achieve the best angle correction effect. In addition, when monitoring in heavy rain or fog or collapse, dust and fog are heavy and easily adhere to the camera, resulting in poor monitoring effect. In order to solve the above problems, this application proposes a UAV monitoring equipment for collapse areas. Summary of the invention

A connecting plate 74 is fixedly installed on one side of the shaft sleeve 73. The connecting plate 74 is fixedly connected to the corresponding wind shield 75.

[0059] Reference Figure 8 The material of the windshield 75 is a plastic memory material, which is used to fold the windshield 75 for storage and reduce wind resistance during movement.

[0060] Reference Figure 6 A fixing plate 76 is fixedly installed on the bottom inner wall of the protective shell 5, and a circular magnetic plate 77 is installed on the fixing plate 76. An annular magnet is installed at the bottom of the connecting ring 71. The diameter of the circular magnetic plate 77 is smaller than the diameter of the annular magnet, and the circular magnetic plate 77 and the side of the annular magnet close to each other are of the same sex.

When the connecting ring 71 is offset, the lateral thrust of the magnetic field can form a reset effect on the connecting ring 71.

[0061] Reference Figure 3 The side of the protective shell 5 is provided with four symmetrically arranged movable holes, which are movably connected to the corresponding fixing rods 78. The movable holes can place the fixing rods 78 and limit the fixing rods 78 and the connecting ring 71 to prevent the connecting ring 71 from deviating from the top of the circular magnetic plate 77.

[0062] Reference Figure 6 and Figure 8 The resistance reduction mechanism 8 also includes a plurality of push rods 83.

The bottom end of the push rod 83 is fixedly installed with a mounting block 84. Two pull ropes 85 are fixedly connected to the mounting block 84. The pull rope 85 is fixedly connected to one side of the wind shield 75. The downward moving ring 81 drives the four positioning rods 82 to move downward, and the positioning rod 82 drives the push rod 83 to push downward. The push rod 83 drives the pull rope 85 through the mounting block 84 to pull and deform the wind shield 75, so that the wind shield 75 forms a folding effect. At the same time, the push rod 83 is slidably connected to the shaft sleeve 73. The cross-section of the push rod 83 is fan-shaped, and the inner ring of the shaft sleeve 73 is fan-shaped, so that a lateral limit is formed between the shaft sleeve 73 and the push rod 83, and then when the shaft sleeve 73 rotates, the push rod 83 can be driven to rotate with it.

[0063] Reference Figure 7 A plurality of slide bars 86 are fixedly mounted on the top of the connecting ring 71, and the slide bars 86 are slidably connected to the movable ring 81. A return spring 87 is sleeved on the slide bars 86, and the return spring 87 is located between the movable ring 81 and the connecting ring 71. Through the sliding connection between the plurality of slide bars 86 and the movable ring 81, the movable ring 81 can be limited so that the movable ring 81 and the connecting ring 71 can only slide up and down.

[0064] Reference Fig. 9The bottom of the installation box 12 is provided with a plurality of air outlet holes 17, the top of the annular air guide box 15 is provided with an annular connecting hole 18, the annular connecting hole 18 and the air outlet holes 17 are communicated with each other, and a positioning ring 19 is fixedly installed at the bottom of the installation box 12, and an annular card groove 20 is provided on the inner side of the positioning ring 19, and four symmetrically arranged positioning blocks 21 are slidably connected on the inner wall of the annular card groove 20, and the four positioning blocks 21 are fixedly connected to the annular air guide box 15, the port of the nozzle 16 is deflected by thirty degrees to the camera 13, and the nozzle 16 is deflected by fifteen degrees along the tangent direction of the annular air guide box 15, and the installation box 12 is connected to the annular connecting hole 18 through the air outlet hole 17. The connection allows the wind force on the blower 14 to act on the annular air guide box 15 through the mounting box 12 and be sprayed out through multiple nozzles 16. The nozzles 16 are set at a 15-degree angle along the tangent direction of the annular air guide box 15, so that when the nozzles 16 discharge air, the reverse force of the wind drives the annular air guide box 15 to rotate automatically. At the same time, with the port of the nozzle 16 being set at a 30-degree angle toward the camera 13, dust and rainwater directly below the camera 13 can be removed, thereby ensuring clear shooting of the camera 13. At the same time, the sliding connection between the annular slot 20 and the four positioning blocks 21 can limit the annular air guide box 15.

[0065] Working principle: When working, the fuselage 1 rotates the propeller blades 10 in the four annular fixed wings 4 to form a take-off and landing operation. When the fuselage 1 is at a high altitude, the wind in the air acts on the wind shield 75. Through the effect of different wind directions, the wind shield 75 is blown to form a vertical effect with the wind direction, so that the wind shield 75 directly forms an action force with the blowing air. The wind shield 75 acts on the fixing rod 78 through the connecting plate 74 and the shaft sleeve 73, and under the action of the connecting ring 71, it drives multiple fixing rods 78 to move synchronously. The fixing rod 78 drives the annular fixed wing 4 to change its angle through the pull rod 72 and the isolation cover 9, so that the angle of the annular fixed wing 4 is biased towards the direction of wind force, thereby balancing the wind blowing. The motor 67 is started to move the body 1 laterally. When the body 1 is actively flying, the motor 67 switch is started. The output shaft of the motor 67 is meshed with the inner gear ring 69 through the driving gear 68, so that the driving ring 61 can be driven to rotate. The driving ring 61 drives the cylinder 63 to move to the direction in which it needs to move forward, and the switch of the cylinder 63 is started. The piston of the cylinder 63 drives the top block 64 to move downward. The top block 64 is mutually clamped with the wedge-shaped frustum plate 66 through the arc-shaped groove 65, so that the moving direction of the wedge-shaped frustum plate 66 can be positioned. Then, under the push of the top block 64, the moving ring 81 can be pushed to move in one direction and can be pushed to move downward. The moving ring 81 is limited by a plurality of slide bars 86, thereby driving The connecting ring 71 moves in one direction and drives the pull rod 72 to pull through the fixing rod 78. At the same time, due to the connection of the spherical universal joint, the fixing rod 78 and the pull rod 72 can rotate in any direction, and the corresponding annular fixed wing 4 is driven to change its angle through the pull rod 72 and the isolation cover 9, so as to perform directional flight. At this time, the moving ring 81 drives the positioning rod 82 to move downward, and the positioning rod 82 drives the mounting block 84 to move downward through the top rod 83, driving the pull rope 85 to pull, so that the windshield 75 can be pulled and deformed, so that the windshield 75 forms a folding effect. At the same time, the top rod 83 is connected to the sleeve 73 through sliding. The cross section of the top rod 83 is fan-shaped, and the inner ring of the sleeve 73 is fan-shaped, so that the sleeve 73 can be folded. A lateral limit is formed between the sleeve 73 and the top rod 83, so that when the sleeve 73 rotates, the top rod 83 can be driven to rotate accordingly. At the same time, the mounting box 12 is connected to the annular connecting hole 18 through the air outlet hole 17, so that the wind force on the blower 14 acts on the annular air guide box 15 through the mounting box 12 and is sprayed out through multiple nozzles 16. The nozzles 16 are set to be tilted fifteen degrees along the tangential direction of the annular air guide box 15, so that when the nozzles 16 discharge air, the reverse force of the wind force drives the annular air guide box 15 to rotate automatically. At the same time, when the port of the nozzle 16 is tilted thirty degrees toward the camera 13, the dust and rainwater directly below the camera 13 can be removed, thereby ensuring clear shooting of the camera 13.
