Abstract

The present invention belongs to the field of aerial photography technology, and specifically relates to a camera mounting device for surveying and mapping aerial photography, including a vertical box shell. Both ends of the surface of the vertical box shell are fixedly connected with limiting rings. Both sides of the inner cavity of the vertical box shell are slidably connected with a photography device. Both sides of the inner cavity of the vertical box shell are fixedly connected with external side arms, and a control motor is fixedly connected to the center of the bottom of the inner cavity of the external side arm. When the drone is flying in the air, the fuselage is very likely to shake violently, which will cause the aerial survey camera suspended at the bottom to shake violently during shooting. Moreover, when the fuselage turns, the suspended camera is very likely to be thrown off due to the action of centrifugal force, and the connecting frame may be disconnected after long-term use. After the photography device is separately installed from the fixed vertical box shell, the torque force received by the connection point at the top of the threaded barrel can be reduced, thereby reducing the problem of the connecting frame being bent and broken due to inertia.

Description

Technical Field

[0001] The present invention belongs to the technical field of aerial photography, and more specifically, it is a camera mounting device for surveying and mapping aerial photography. Background Art

[0002] At present, aircrafts, such as unmanned aircrafts, also known as drones, have been increasingly widely used. Drones have the advantages of small size, light weight, flexibility, rapid response, unmanned operation, and low operation requirements. By mounting an aerial camera on a gimbal, functions such as real-time image transmission and detection in high-risk areas can also be achieved, making it a powerful supplement to satellite remote sensing and traditional aerial remote sensing.

[0003] The drone aerial survey camera bracket is usually installed at the bottom of the drone. However, when the drone is flying in the air, due to the high-speed vibration of its own engine and the influence of wind, the fuselage is prone to violent shaking, which in turn causes the aerial survey camera suspended at the bottom to shake violently during shooting. Moreover, when the fuselage turns, the suspended camera is very likely to be thrown off due to the centrifugal force, and long-term use may lead to the disconnection of the connecting frame and the problem of the camera falling, so improvement is needed. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a camera mounting device for surveying and mapping aerial photography, including a vertical box shell. Both ends of the surface of the vertical box shell are fixedly connected with limiting rings. Both sides of the inner cavity of the vertical box shell are slidably connected with a photography device. Both sides of the inner cavity of the vertical box shell are fixedly connected with external side arms. The center of the bottom of the inner cavity of the external side arm is fixedly connected with a control motor. The top of the output shaft of the control motor is fixedly connected with a threaded rotating cylinder. Both sides of the surface of the threaded rotating cylinder are rotatably connected with traction connecting rods. The top of the traction connecting rod is rotatably connected with a clamping rotating sleeve, including a buffer component, which can buffer the sliding photography device. The buffer component includes a sliding sleeve disc. Both sides of the bottom of the inner cavity of the sliding sleeve disc are fixedly connected with telescopic sleeves through through holes. The bottom end of the telescopic sleeve is fixedly connected with a pressurizing device. The center of the bottom of the inner cavity of the sliding sleeve disc is slidably connected with a reinforcing ring. The inner cavity of the reinforcing ring is evenly provided with rotating joint rods. Both sides of the surface of the reinforcing ring are slidably connected with the inner cavity of the sliding sleeve disc through filling sliders. The inner cavity of the reinforcing ring is fixedly connected with a plugging rod; when using this device, after assembling the photography device, it is installed inside the vertical box shell. Then, for the external side arms on both sides of the vertical box shell, the control motor at the bottom of its inner cavity controls the threaded rotating cylinder to rotate self, so that the traction connecting rods on both sides are drawn upwards. Then, the traction connecting rods are inserted into the bottom of the inner cavity of the aircraft through the external rings sleeved at the top. When the aircraft is flying, it can hang the vertical box shell at the bottom. When the unmanned aerial vehicle is flying in the air, due to the high-speed vibration of its own engine and the influence of wind force, the fuselage is very easy to shake violently, which will cause the aerial survey camera hanging at the bottom to shake violently during shooting. And when the fuselage turns, the hanging camera is very easy to be thrown off due to the action of centrifugal force, and long-term use may cause the connecting frame to break. After separating and installing the photography device from the fixed vertical box shell, this device can reduce the torque force received by the connection point at the top of the threaded rotating cylinder, thereby reducing the problem that the connecting frame is bent and broken due to inertia.

[0005] Preferably, the pressurizing device includes a pressurizing cylinder. At the axles of both ends of the inner cavity of the pressurizing cylinder, outer connecting pipes are fixedly connected through through ports. A spring sleeve is slidably connected to one end of the inner cavity of the pressurizing cylinder away from the outer connecting pipes. Pressure-dividing insertion rods are fixedly connected to both sides of the inner cavity of the pressurizing cylinder. A bridging connecting rod is fixedly connected to the end of the pressure-dividing insertion rod away from the pressurizing cylinder. A pressure sensor is fixedly connected to the end of the bridging connecting rod away from the bridging connecting rod. When this device is in use, a photographic device can be mounted at the bottom of an aircraft to achieve aerial photography work. When a drone is flying in the air, operations such as sharp turns or decelerations and accelerations are likely to occur. At this time, relative movement will occur between the aircraft body and the photographic device below due to inertia. At this time, the photographic device will pull the sliding sleeve discs on the upper and lower sides to slide in the sockets at the axis of the inner cavity of the vertical box housing. The sliding sleeve discs will sway in the middle of the inner cavity of the vertical box housing through the spring belts in the inner cavity, thereby separating the vertical box housing from the photographic device, reducing the inertial effect on the vertical box housing, and thus making the videos and photos taken during aerial photography clearer.

[0006] Preferably, a socket ring is fixedly connected to the middle of the surface of the pressurizing cylinder. And on the side of the socket ring surface away from the pressure sensor, a guiding slide rail is slidably connected through a sliding pull plate. The surface of the guiding slide rail is fixedly connected to the middle of the inner cavity of the external side arm. The number of the outer connecting pipes is four. The end of the outer connecting pipe away from the pressurizing cylinder is fixedly connected to the inner cavity of the spring sleeve. During the aerial photography process of the aircraft, since the one-way cameras on both sides are facing the flight trajectory of the aircraft, the one-way cameras can perform aerial photography work during the normal flight of the aircraft. When a drone is flying in the air, operations such as sharp turns or decelerations and accelerations are likely to occur. At this time, relative movement will occur between the aircraft body and the photographic device below due to inertia. The photographic device of this device is installed inside the buffer component, and the weight of the photographic device itself is relatively higher than that of other components. So at this time, the photographic device will pull the sliding sleeve discs on the upper and lower sides to slide in the sockets at the axis of the inner cavity of the vertical box housing. The sliding sleeve discs will sway in the middle of the inner cavity of the vertical box housing through the spring belts in the inner cavity, thereby separating the vertical box housing from the photographic device.

[0007] Preferably, the number of the reinforcing rings is two, and four rotating joint rods are arranged in the inner cavity of each reinforcing ring. Both sides of the surface of the reinforcing ring are slidably connected with the inner cavity of the sliding sleeve disc through guiding chutes. The number of the sliding sleeve discs is two, and the middle part of the inner cavity of the sliding sleeve disc is slidably connected with the axis of the inner cavity of the vertical box shell through a small spring belt. When the pressure cylinder is extruded, according to the reaction force, the corresponding spring sleeve in the inner cavity will also be affected by the pressure. When the pressure cylinder extrudes the telescopic sleeve excessively, the spring sleeve can relieve the pressure by expanding the internal space. However, the inner cavity of the spring sleeve must always be kept in a sealed state. Therefore, the pressure-dividing inserting rods on both sides will monitor the pressure in the inner cavity of the pressure cylinder. When the spring sleeve leaks air, the pressure in the inner cavity of the pressure cylinder will increase due to the air leakage of the spring sleeve. At this time, the pressure sensor will sense the increase in the pressure in the inner cavity of the pressure cylinder through the bridging connecting rod.

[0008] Preferably, one end of the pressure-dividing inserting rod away from the bridging connecting rod extends into the interior of the pressure cylinder. One end of the inner cavity of the spring sleeve is fixedly connected with the surface of the outer connecting pipe. One end of the bridging connecting rod away from the pressure-dividing inserting rod extends into the interior of the pressure sensor. The number of the pressure sensors is four. The top end of the traction connecting rod is fixedly connected with the bottom of the inner cavity of the aircraft through a clamping rotating sleeve. Since the aircraft is in flight, due to the high-speed vibration of its own engine and the influence of wind force, the fuselage is prone to violent shaking, which will cause violent shaking when the aerial survey camera suspended at the bottom takes pictures. At this time, the internal buffer components are needed for reinforcement. When the aircraft body performs operations such as accelerating and changing direction, the guiding slide rails on both sides will pull the pressure cylinder upward through the connecting rod. At this time, the pressure cylinders on both sides will rise vertically, squeezing the telescopic sleeve above. At this time, the pressure in the inner cavity of the upper sliding sleeve disc increases, and then squeezes the surface of the middle reinforcing ring. At this time, the reinforcing rings will rotate towards the side close to the adjustment rotating machine along the rotating joint rods, and reinforce the adjustment rotating machine through the inserting rods on the concave surface, avoiding the loosening of the upper adjustment rotating machine due to inertia; during flight, the guiding slide rails on both sides will pull the pressure cylinder downward through the connecting rod to reinforce the lower adjustment rotating machine. At this time, the lower adjustment rotating machine is not easy to loosen when affected by wind force. Under normal circumstances, since the two reinforcing rings do not squeeze the adjustment rotating machine on both sides. This device can change the reinforcement of the adjustment rotating machines on both sides through the pressurizing device, so that when the aircraft performs operations such as accelerating and changing direction, it can avoid the problem of loosening of the upper adjustment rotating machine due to inertia; reinforce the lower adjustment rotating machine. At this time, the lower adjustment rotating machine is not easy to loosen when affected by wind force, and at the same time keep the adjustment rotating machines on both sides with good heat dissipation performance.

[0009] Preferably, the photographic device includes a one-way camera. A built-in sliding plate is slidably connected to the surface of the one-way camera. A straight rod housing is fixedly connected to the side of the one-way camera surface away from the built-in sliding plate. A laser end rod is fixedly connected to the inner cavity of the straight rod housing. An axial center rotating rod is fixedly connected to the end of the straight rod housing away from the built-in sliding plate. Adjusting rotating machines are rotatably connected to both sides of the inner cavity of the axial center rotating rod. A connecting inner sleeve is sleeved on the surface of the output shaft of the adjusting rotating machine, and the output shaft of the adjusting rotating machine is clamped with the inner cavity of the axial center rotating rod through the connecting inner sleeve. Docking plates are rotatably connected to both sides of the inner cavity of the axial center rotating rod. When the sliding sleeve plate slides, the photographic device also slides directionally along the cutting grooves on both sides of the vertical box housing by pulling the built-in sliding plate. Therefore, the built-in sliding plate will surely be pulled and twisted and offset by the one-way camera. Since the surface of the docking plate is fixed by the sensors on both sides, at this time, the laser end rods on both sides will twist relative to the docking plate. Therefore, in order to make the laser end rods continue to face the docking plate directly, the adjusting rotating machines on both sides need to twist the axial center rotating rod to rotate the axial center rotating rod back to its original position, thereby adjusting the two one-way cameras back to the position facing forward. The number of the one-way cameras is two. The surface of the one-way camera is slidably connected to the middle of the inner cavity of the built-in sliding plate through a vertical sliding groove. The number of the adjusting rotating machines is two. The surface of the adjusting rotating machine is fixedly connected to the middle of the inner cavity of the sliding sleeve plate. Both sides of the surface of the docking plate are fixedly connected to the surface of the sensor through a cutting groove.

[0010] Preferably, the built-in sliding plate includes a modified cut block. Oblique cutting grooves are evenly formed in the inner cavity of the modified cut block. Arc-shaped rings are fixedly connected to both ends of the inner cavity of the built-in sliding plate. A counterweight plate is rotatably connected to the surface of the arc-shaped ring. A spring arc plate is fixedly connected to the bottom of the surface of the counterweight plate. When the aircraft is in flight, since the front of the one-way camera is the windward side, the wind force will pass through the vertical cutting groove in the middle of the built-in sliding plate. At this time, the air flow will pass through the oblique cutting grooves of the modified cut block and then push it open. The air flow passing through the modified cut block makes a sound due to air vibration, thereby dispersing the nearby birds. Since the wind force is unstable, after the counterweight plate is blown open by the strong wind, it will soon be pulled back to its original position by the spring arc plate and then hit the side of the modified cut block, generating vibration for the entire built-in sliding plate.

[0011] Preferably, the number of the built-in sliding plates is two. Both sides of the inner cavity of the built-in sliding plate are slidably connected to the middle of the inner cavity of the vertical box shell through the cutting notch openings. The surface of the modified cutting block is fixedly connected to the inner cavity of the built-in sliding plate through the vertical cutting groove. The surface of the counterweight plate is pressed against one side of the surface of the modified cutting block close to the central rotating rod. The bottom end of the spring arc plate is fixedly connected to the inner cavity of the built-in sliding plate. The surface of the output shaft of the adjustment rotating machine is slidably connected to the inner cavity of the docking plate. One end of the laser end rod far from the one-way camera is perpendicular to one side of the surface of the docking plate. The central axis of the inner cavity of the adjustment rotating machine extends to the inside of the aircraft through the connecting wire. When the device flies with the aircraft, due to the wind resistance, the air flow of the modified cutting block at the air inlet can make a sound due to air vibration, thereby dispersing the nearby birds and avoiding the flying birds from hitting the aircraft and the device. Moreover, the counterweight plate close to the modified cutting block can continuously impact the modified cutting block through the unstable wind resistance, shaking off the impurities stuck in the inner cavity of the modified cutting block and avoiding the problem that the whistle opening of the modified cutting block is blocked.

[0012] Preferably, the limiting ring includes an outer ring shell. The inner cavity of the outer ring shell is evenly provided with directional sliding plates. The middle of the inner cavity of the directional sliding plate close to the adjustment rotating machine is fixedly connected with a buffer suction cup. Both sides of the directional sliding plate are fixedly connected with spring sliding rods. One side of the surface of the directional sliding plate far from the buffer suction cup is slidably connected with a pressing rotating ring. The inner cavity of the pressing rotating ring is evenly provided with vertical insertion rods. After the device is assembled, the side surface of the sliding sleeve disc will face the buffer suction cup. During the buffer sliding process of the sliding sleeve disc, the side surface of the sliding sleeve disc will continuously collide with the surrounding sliding sleeve discs, thereby limiting the sliding range of the sliding sleeve disc and avoiding the problem that the one-way camera is thrown off due to the too large sliding range of the sliding sleeve disc. In necessary cases, the outer surface of the pressing rotating ring can be rotated to make the vertical insertion rods in the inner cavity of the pressing rotating ring slide each directional sliding plate towards the side surface of the sliding sleeve disc, thereby adsorbing and fixing the sliding sleeve disc and ensuring the overall stability of the vertical box shell.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. When the device is in use, the photographic device can be installed at the bottom of the aircraft to achieve aerial photography work. When the drone is flying in the air, it is easy to perform operations such as sharp turns or deceleration and acceleration. At this time, the fuselage and the photographic device below will move relatively due to inertia. At this time, the photographic device will pull the sliding sleeve discs on the upper and lower sides to slide in the sockets at the central axis of the inner cavity of the vertical box shell. The sliding sleeve discs shake in the middle of the inner cavity of the vertical box shell through the spring belts in the inner cavity, thereby separating the vertical box shell from the photographic device and reducing the inertial force received by the vertical box shell, so that the aerial photography videos and photos are clearer.

[0015] 2. When the drone is flying in the air, due to the high-speed vibration of its own engine and the influence of wind force, the fuselage is prone to violent shaking, which will cause the aerial survey camera suspended at the bottom to shake violently during shooting. Moreover, when the fuselage turns, the suspended camera is very likely to be thrown off due to the centrifugal force, and long-term use may cause the connecting frame to break. After the device separates and installs the photographic device from the fixed vertical housing, the torque force on the connection point at the top of the threaded barrel can be reduced, thereby reducing the problem of the connecting frame being bent and broken due to inertia.

[0016] 3. The device can change the reinforcement of the two-sided adjustment rotators through the pressurizing device, so that when the aircraft is performing operations such as accelerating and changing direction, the adjustment rotator above can be prevented from loosening due to inertia; the adjustment rotator below is reinforced, and at this time, the adjustment rotator below is not easily loosened after being affected by the wind force, and at the same time, the two-sided adjustment rotators maintain good heat dissipation performance.

[0017] 4. When the device is flying with the aircraft, through the wind resistance it receives, the air flow of the modified block at the air inlet can make a sound due to air vibration, thereby dispersing the nearby birds and preventing the flying birds from hitting the aircraft and the device. Moreover, the counterweight plate close to the modified block can continuously impact the modified block through the unstable wind resistance, shaking off the impurities stuck in the inner cavity of the modified block and avoiding the problem of the whistle opening of the modified block being blocked.

[0018] 5. After the device is assembled, the side of the sliding sleeve disc will face the buffer suction cup. During the buffer sliding process of the sliding sleeve disc, the side of the sliding sleeve disc will continuously collide with the surrounding sliding sleeve discs, thereby limiting the sliding range of the sliding sleeve disc and avoiding the problem of the single-direction camera being thrown off due to the too large sliding range of the sliding sleeve disc. In necessary cases, the outer surface of the extrusion rotating ring can be rotated, so that the vertical insertion rod in the inner cavity of the extrusion rotating ring slides each directional slide plate towards the direction close to the side of the sliding sleeve disc, thereby adsorbing and fixing the sliding sleeve disc to ensure the overall stability of the vertical housing.

Specific embodiments

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0029] Example 1, please refer to Figures 1 - 5, the present invention provides a technical solution: a camera mounting device for surveying and mapping aerial photography, including a vertical box housing 1. Both ends of the surface of the vertical box housing 1 are fixedly connected with limit rings 3. On both sides of the inner cavity of the vertical box housing 1, a photographic device 6 is slidably connected. On both sides of the inner cavity of the vertical box housing 1, an external side arm 11 is fixedly connected. At the center of the bottom of the inner cavity of the external side arm 11, a control motor 13 is fixedly connected. At the top of the output shaft of the control motor 13, a threaded drum 14 is fixedly connected. On both sides of the surface of the threaded drum 14, a traction connecting rod 12 is rotatably connected. The top end of the traction connecting rod 12 is rotatably connected with a clamping sleeve, including a buffer component 4. This buffer component 4 can buffer the sliding photographic device 6. The buffer component 4 includes a sliding sleeve plate 41. On both sides of the bottom of the inner cavity of the sliding sleeve plate 41, a telescopic sleeve 42 is fixedly connected through a through hole. The bottom end of the telescopic sleeve 42 is fixedly connected with a pressurizing device 5. At the center of the bottom of the inner cavity of the sliding sleeve plate 41, a reinforcing ring 44 is slidably connected. Inside the cavity of the reinforcing ring 44, rotating joint rods 45 are evenly arranged. On both sides of the surface of the reinforcing ring 44, it is slidably connected with the inner cavity of the sliding sleeve plate 41 through filling sliders. Inside the cavity of the reinforcing ring 44, a plugging rod 46 is fixedly connected;

[0030] The pressurizing device 5 includes a pressurizing cylinder 51. At the center of both ends of the inner cavity of the pressurizing cylinder 51, an external connecting pipe 52 is fixedly connected through a through hole. At one end of the inner cavity of the pressurizing cylinder 51 far from the external connecting pipe 52, a spring sleeve 53 is slidably connected. On both sides of the inner cavity of the pressurizing cylinder 51, a voltage dividing plug rod 54 is fixedly connected. The end of the voltage dividing plug rod 54 far from the pressurizing cylinder 51 is fixedly connected with a bridging connecting rod 55. The end of the bridging connecting rod 55 far from the bridging connecting rod 55 is fixedly connected with a pressure sensor 56.

[0031] In the middle of the surface of the pressurizing cylinder 51, a socket ring is fixedly connected. And on one side of the surface of the socket ring far from the pressure sensor 56, it is slidably connected with a guiding slide rail 43 through a sliding pull plate. The surface of the guiding slide rail 43 is fixedly connected with the middle of the inner cavity of the external side arm 11. The number of the external connecting pipes 52 is four. The end of the external connecting pipe 52 far from the pressurizing cylinder 51 is fixedly connected with the inner cavity of the spring sleeve 53.

[0032] The number of the reinforcing rings 44 is two. And in the cavity of each reinforcing ring 44, four rotating joint rods 45 are arranged. On both sides of the surface of the reinforcing ring 44, it is slidably connected with the inner cavity of the sliding sleeve plate 41 through guiding chutes. The number of the sliding sleeve plates 41 is two. The middle of the inner cavity of the sliding sleeve plate 41 is slidably connected with the center of the inner cavity of the vertical box housing 1 through a small spring band.

[0033] One end of the pressure-dividing rod 54 away from the bridging connecting rod 55 extends to the interior of the pressurizing cylinder 51, the inner cavity of the spring sleeve 53 is fixedly connected to one end of the surface of the external tube 52, and one end of the bridging connecting rod 55 away from the pressure-dividing rod 54 extends to the interior of the pressure sensor 56. There are four pressure sensors 56, and the top end of the traction connecting rod 12 is fixedly connected to the bottom of the inner cavity of the aircraft through a snap-on rotating sleeve.

[0034] When using the device, the photographic device 6 is assembled and installed inside the vertical box shell 1, and then the side arms 11 are connected to the outside of the vertical box shell 1. The control motor 13 at the bottom of the inner cavity controls the threaded rotating cylinder 14 to rotate, so that the traction connecting rods 12 on both sides are moved upward, and then the traction connecting rods 12 are inserted into the bottom of the inner cavity of the aircraft through the external connecting ring on the top. The aircraft can suspend the vertical box shell 1 at the bottom when flying.

[0035] During the aerial photography of the aircraft, since the one-way cameras 61 on both sides are facing the flight trajectory of the aircraft, the one-way cameras 61 can perform aerial photography during the normal flight of the aircraft. When the drone is flying in the air, it is easy to make sudden turns or deceleration and acceleration. At this time, the body and the photographic device 6 below will move relative to each other due to inertia. The photographic device 6 of the device is installed inside the buffer component 4, and the counterweight of the photographic device 6 itself is higher than other components. Therefore, at this time, the photographic device 6 will pull the sliding sleeves 41 on the upper and lower sides to slide in the sockets at the axis center of the inner cavity of the vertical box shell 1. The sliding sleeves 41 swing in the middle of the inner cavity of the vertical box shell 1 through the spring belt of the inner cavity, thereby separating the vertical box shell 1 from the photographic device 6 and reducing the inertia of the vertical box shell 1.

[0036] When the aircraft is flying, its engine vibrates at high speed, and due to the influence of wind, the fuselage is prone to violent shaking, which in turn causes the aerial survey camera suspended at the bottom to shake violently when shooting. At this time, the internal buffer component 4 needs to be reinforced. When the body is accelerating and changing direction, the guide rails 43 on both sides pull the pressurizing cylinder 51 upward through the connecting rod. At this time, the pressurizing cylinders 51 on both sides rise vertically and squeeze the telescopic sleeve 42 above. At this time, the pressure in the inner cavity of the upper sliding sleeve 41 increases, thereby squeezing the surface of the reinforcement ring 44 in the middle. At this time, the reinforcement ring 44 rotates along the rotating joint rod 45 to the side close to the adjustment rotating machine 65, and the adjustment rotating machine 65 is reinforced by the concave plug-in rod 46 to prevent the upper adjustment rotating machine 65 from loosening due to inertia.

[0037] During flight, the guiding slide rails 43 on both sides pull the pressurizing cylinder 51 downward through the connecting rod to reinforce the adjusting rotating machine 65 below. At this time, the adjusting rotating machine 65 below is not easily loosened when affected by wind. Under normal circumstances, since the reinforcing rings 44 on both sides do not squeeze the adjusting rotating machine 65.

[0038] When the pressurizing cylinder 51 is being squeezed, according to the reaction force, the corresponding spring sleeve 53 in the inner cavity will also be subjected to pressure. The spring sleeve 53 can relieve the pressure by expanding the internal space when the pressurizing cylinder 51 squeezes the telescopic sleeve 42 excessively. However, the inner cavity of the spring sleeve 53 must always remain sealed. Therefore, the pressure-dividing insertion rods 54 on both sides will monitor the pressure in the inner cavity of the pressurizing cylinder 51. When the spring sleeve 53 leaks air, the pressure in the inner cavity of the pressurizing cylinder 51 will increase due to the air leakage of the spring sleeve 53. At this time, the pressure sensor 56 will sense the increase in the pressure in the inner cavity of the pressurizing cylinder 51 through the bridging connecting rod 55.

[0039] Example 2, please refer to Figures 1 - 8 , the present invention provides a technical solution: on the basis of Example 1, the photographing device 6 includes a one-way camera 61. A built-in sliding plate 7 is slidably connected to the surface of the one-way camera 61. A straight rod shell 62 is fixedly connected to the side of the one-way camera 61 surface away from the built-in sliding plate 7. A laser end rod 63 is fixedly connected to the inner cavity of the straight rod shell 62. An axial center rotating rod 64 is fixedly connected to the end of the straight rod shell 62 away from the built-in sliding plate 7. Adjusting rotating machines 65 are rotatably connected to both sides of the inner cavity of the axial center rotating rod 64. A connecting inner sleeve is sleeved on the surface of the output shaft of the adjusting rotating machine 65, and the output shaft of the adjusting rotating machine 65 is clamped with the inner cavity of the axial center rotating rod 64 through the connecting inner sleeve. Docking plates 66 are rotatably connected to both sides of the inner cavity of the axial center rotating rod 64.

[0040] The number of one-way cameras 61 is two. The surface of the one-way camera 61 is slidably connected to the middle of the inner cavity of the built-in sliding plate 7 through a vertical sliding groove. The number of adjusting rotating machines 65 is two. The surface of the adjusting rotating machine 65 is fixedly connected to the middle of the inner cavity of the sliding sleeve plate 41. Both sides of the surface of the docking plate 66 are fixedly connected to the surface of the pressure sensor 56 through cut grooves.

[0041] The built-in sliding plate 7 includes modified cut blocks 71. Oblique cut grooves are uniformly formed in the inner cavity of the modified cut blocks 71. Arc-shaped rings 72 are fixedly connected to both ends of the inner cavity of the built-in sliding plate 7. A counterweight plate 73 is rotatably connected to the surface of the arc-shaped ring 72. A spring arc plate 74 is fixedly connected to the bottom of the surface of the counterweight plate 73.

[0042] The number of the built-in sliding plates 7 is two. Both sides of the inner cavity of the built-in sliding plate 7 are slidably connected to the middle part of the inner cavity of the vertical box shell 1 through the cut slots. The surface of the modified cutting block 71 is fixedly connected to the inner cavity of the built-in sliding plate 7 through the vertical cut slot. The surface of the counterweight plate 73 is pressed against one side of the surface of the modified cutting block 71 close to the axis rotating rod 64. The bottom end of the spring arc plate 74 is fixedly connected to the inner cavity of the built-in sliding plate 7.

[0043] The surface of the output shaft of the adjustment rotating machine 65 is slidably connected to the inner cavity of the docking disc 66. One end of the laser end rod 63 far from the one-way camera 61 is perpendicular to one side of the surface of the docking disc 66. The axis at the center of the inner cavity of the adjustment rotating machine 65 extends to the inside of the aircraft through the connecting wire.

[0044] When the aircraft is in flight, since the front of the one-way camera 61 is the windward side, the wind force will pass through the vertical cut slot in the middle of the built-in sliding plate 7. At this time, the air flow will pass through the inclined cut slot of the modified cutting block 71 and then push it open. The air flow passing through the modified cutting block 71 makes a sound due to air vibration, thereby dispersing the nearby birds. Since the wind force is unstable, after the counterweight plate 73 is blown open by the strong wind, it will soon be pulled back to its original position by the spring arc plate 74, and then hit the side of the modified cutting block 71, generating vibration for the entire built-in sliding plate 7, so as to prevent the air dust and impurities from blocking the through hole of the built-in sliding plate 7.

[0045] When the sliding sleeve disc 41 slides, the photography device 6 also slides directionally along the cut slots on both sides of the vertical box shell 1 by pulling the built-in sliding plate 7. Therefore, the built-in sliding plate 7 will surely be pulled and twisted and offset by the one-way camera 61. Since the surface of the docking disc 66 is fixed by the sensors 56 on both sides, at this time, the two laser end rods 63 will twist relative to the docking disc 66. Therefore, in order to make the laser end rods 63 continue to face the docking disc 66 directly, it is necessary to rotate the axis rotating rod 64 by the adjustment rotating machines 65 on both sides, so that the axis rotating rod 64 rotates back to its original position, and then adjust the two one-way cameras 61 back to the position facing forward.

[0046] The limit ring 3 includes an outer ring shell. The inner cavity of the outer ring shell is evenly provided with directional sliding plates 33. The middle part of the inner cavity of the directional sliding plate 33 close to the adjustment rotating machine 65 is fixedly connected with a buffer suction cup 35. Both sides of the directional sliding plate 33 are fixedly connected with spring sliding rods 34. The side of the surface of the directional sliding plate 33 far from the buffer suction cup 35 is slidably connected with an extrusion rotating ring 31. The inner cavity of the extrusion rotating ring 31 is evenly provided with vertical insertion rods 32.
