[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] I. This utility model, by setting up movable mounting components and collecting shock absorption components, etc., through the cooperation between the components, enables the movable mounting components to initially absorb vibrations through elastic buffering and sliding shock absorption. At the same time, the collecting shock absorption components can use the airflow of the flight to drive the sealing plate to rotate, compress the airflow to store it in the air tank and inflate the airbag. After the airbag expands, it applies stable pressure to the positioning block. With the help of the air pressure valve to regulate the internal air pressure, the device can effectively reduce the vibration generated during the flight of the UAV and prevent the remote sensing device body from experiencing a decrease in data acquisition accuracy and component loosening and damage due to vibration.

[0019] II. This utility model, by setting up components such as sealing blocks, guide rods, limiting posts, elastic pawls, air plates, and buffer plates, ensures stable airflow collection and discharge through the cooperation of the sealing block and the pushing block. The sliding connection between the guide rod and the limiting post restricts horizontal swaying. The meshing of the elastic pawl and the ratchet ensures unidirectional rotation of the connecting post. The air plate and the honeycomb partition make the pressure distribution uniform. The buffer plate and the shock-absorbing holes further disperse vibration energy. These components can provide shock absorption protection for the remote sensing device body through multi-stage shock absorption and stabilization structure, thereby achieving the effect of improving the shock absorption effect, enhancing equipment stability, and extending service life.

[0020] Third, this utility model, by setting up components such as a cleaning nozzle, a rotating blade, and a shroud, and by connecting the air tank to the cleaning nozzle, uses the stored gas to clean the surface of the remote sensing device. The rotating blade, driven by the airflow, assists the connecting column in rotating to improve the air storage efficiency. The shroud ensures that the rotating blade stably receives the airflow, thereby achieving the goal of keeping the surface of the remote sensing device clean while reducing vibration, and avoiding dust affecting the monitoring effect.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] See attached document Figure 1-5 A remote sensing device for urban climate change includes: a remote sensing device body 1 and a drone body 2. The drone body 2 is located on top of the remote sensing device body 1. A movable mounting assembly 3 is provided at the bottom of the drone body 2. The movable mounting assembly 3 includes a fixing frame 31, which is fixedly connected to the bottom of the drone body 2. A slider 32 is slidably connected to the inner side of the fixing frame 31. A clamping plate 33 is elastically connected to the inner side of the slider 32 by a spring. The bottom of the clamping plate 33 is inclined. A positioning block 34 is slidably connected to the top of the clamping plate 33. The bottom of the positioning block 34 is fixedly connected to the remote sensing device body 1. A damping spring 35 is fixedly connected to the top of the slider 32. The other end of the damping spring 35 is fixedly connected to the inside of the fixing frame 31.

[0031] The bottom of the UAV body 2 is equipped with a shock-absorbing assembly 4, which includes a movable ring 41. The movable ring 41 is fixedly connected to the bottom of the UAV body 2, and the front of the movable ring 41 is connected to an air inlet 42. The inside of the movable ring 41 is rotatably connected to a connecting post 43. The outside of the connecting post 43 is elastically connected to several sets of sealing plates 44 by spring embedding. The air outlet of the movable ring 41 is connected to an air tank 45 in one direction through a hose. The air outlet of the air tank 45 is connected to an airbag 46 in one direction. The airbag 46 is fixedly connected to the inside of the fixed frame 31 and is located on top of the positioning block 34. One side of the airbag 46 is connected to an air pressure valve 47. The vibration generated by the UAV body 2 during flight is first transmitted to the fixed frame 31. The slider 32 inside the fixed frame 31 can slide along the fixed frame 31 under the action of the damping spring 35, initially buffering the vibration. At the same time, the remote sensing device body 1 is connected to the card plate 33 inside the slider 32 through the positioning block 34. The bottom of the clamping plate 33 is inclined to facilitate the quick insertion of the positioning block 34, and the clamping plate 33 is elastically connected by a spring to further absorb vibration. In addition, when the UAV is flying, the airflow will enter the interior of the movable ring 41 through the air inlet 42 on the front of the movable ring 41. The airflow pushes the connecting column 43 to rotate through the sealing plate 44. Under the action of the spring, the sealing plate 44 is tightly attached to the inner wall of the movable ring 41. As the connecting column 43 rotates, it pushes the airflow to the air outlet of the movable ring 41. The airflow enters the air storage tank 45 through the hose for storage. The gas in the air storage tank 45 then enters the airbag 46 in one direction to inflate the airbag 46. The inflated airbag 46 applies stable pressure to the top of the positioning block 34. With the help of the damping spring 35, the vibration is further weakened. When the airbag 46 generates sudden pressure due to vibration and the internal air pressure is too high, the air pressure valve 47 can release some gas in time to avoid damage to the airbag 46 due to overpressure. This effectively solves the problem of low data acquisition accuracy and easy loosening and damage of components caused by vibration in existing remote sensing devices.

[0032] The top of the positioning block 34 is fixedly connected to a guide rod 7, and a limit post 8 is slidably connected to the surface of the guide rod 7. The limit post 8 is fixedly connected to the bottom of the UAV body 2, and a support ring 9 is elastically connected inside the limit post 8 via a spring. The guide rod 7 at the top of the positioning block 34 is slidably connected inside the limit post 8. The limit post 8 is fixed to the bottom of the UAV body 2, which can limit the movement direction of the positioning block 34, prevent the remote sensing device body 1 from swaying in the horizontal direction, and ensure the stability of the remote sensing device body 1. At the same time, the support ring 9, which is elastically connected inside the limit post 8 via a spring, will contact the bottom of the guide rod 7. When the remote sensing device body 1 is subjected to downward vibration, the guide rod 7 will compress the spring of the support ring 9. The reaction force generated by the spring can buffer the downward vibration. Together with the movable mounting component 3 and the other structures of the collection and shock absorption component 4, the overall shock absorption effect is further improved, and the impact of vibration on the remote sensing device body 1 is reduced.

[0033] The movable ring 41 is elastically connected to a sealing block 5 via a spring. One side of the sealing block 5 is inclined and located outside the air outlet of the movable ring 41. A pushing block 6 is fixedly connected to one side of the sealing plate 44. The sealing block 5 inside the movable ring 41 is elastically connected via a spring, allowing it to tightly fit against the inner wall of the movable ring 41. This blocks the airflow pushed by the sealing plate 44 to the exhaust end of the movable ring 41, which is then output from the exhaust end under the continued pushing of the sealing plate 44, preventing the gas from escaping and being discharged from the exhaust end. After the sealing plate 44 pushes the airflow out, it continues to rotate and pushes the pushing block 6 to move. When the pushing block 6 contacts the inclined side of the sealing block 5, it pushes the sealing block 6 to move. Block 5 compresses the spring and moves it away from the inner wall of the movable ring 41, allowing the sealing plate 44 to pass smoothly through the sealing block 5. After the sealing plate 44 and the pushing block 6 rotate away from the sealing block 5, the sealing block 5 will reset under the action of the spring and seal again, thereby ensuring that the airflow enters the gas storage tank 45 stably and improving the gas storage efficiency to better supply gas to the airbag 46; One side of the connecting column 43 is movably connected to an elastic pawl 10, and the bottom of the elastic pawl 10 is engaged with a ratchet 11, and the ratchet 11 is fixedly connected to the inside of the movable ring 41. The elastic pawl 10 movably connected to one side of the connecting column 43 and the ratchet 11 fixed inside the movable ring 41 are engaged with each other. Under its own elasticity, the elastic pawl 10 always keeps close to the tooth surface of the ratchet 11, which can limit the connection. The rotation direction of the connecting column 43 ensures that it can only rotate unidirectionally in the direction of airflow, preventing reverse rotation due to unstable airflow. The stable unidirectional rotation of the connecting column 43 ensures that the sealing plate 44 continuously and stably pushes the airflow towards the outlet of the movable ring 41, preventing backflow caused by reverse rotation. This ensures that the air tank 45 can stably store airflow, continuously supplying air to the airbag 46, guaranteeing stable pressure from the airbag 46 on the positioning block 34, thereby maintaining the stability of the shock absorption effect. An air plate 12 is fixedly connected to the bottom of the airbag 46, and a honeycomb partition is fixedly connected inside the air plate 12. The air plate 12 is connected to the airbag 46, and the air plate 12 is in communication with the airbag 46. The honeycomb baffles fixed inside the air plate 12, connected by 46, not only distribute the gas evenly to various areas of the air plate 12, keeping the pressure of the air plate 12 on the top of the positioning block 34 uniform and avoiding additional shaking caused by uneven force on the positioning block 34 due to excessive local pressure, but also divide the internal space of the air plate 12 into intervals. When subjected to vibration, the honeycomb baffles will block the rapid flow of gas inside the air plate 12, causing the gas to generate a damping effect during the flow. This damping effect can further absorb and weaken the vibration force transmitted to the air plate 12. Combined with the pressure buffering effect of the air bag 46, it forms a more comprehensive shock absorption effect, thereby further improving the stability of the remote sensing device body 1 in monitoring operations.The gas storage tank 45 is connected to a cleaning nozzle 13 via a hose, and the cleaning nozzle 13 is fixedly connected to the bottom of the UAV body 2. A rotating blade 14 is fixedly connected to the outside of the connecting column 43. The gas storage tank 45 is connected to the cleaning nozzle 13 via a hose and fixed to the bottom of the UAV body 2. When a certain amount of gas is stored in the gas storage tank 45, the cleaning nozzle 13 can be opened by controlling the gas storage tank 45 to blow air to clean the surface of the remote sensing device body 1, removing dust, impurities, etc. attached to the surface, and preventing dust from obstructing the monitoring components of the remote sensing device and affecting the monitoring accuracy. In addition, the rotating blade 14 fixed to the outside of the connecting column 43 will be driven to rotate by the airflow when the UAV is flying. The rotating blade 14 will drive the connecting column 43 to rotate synchronously, which will help enhance the rotational power of the connecting column 43, so that the sealing plate 44 can push the airflow into the gas storage tank 45 more efficiently, improve the gas storage efficiency, ensure the air supply required for shock absorption, and achieve the cleaning function of the remote sensing device body 1.

[0034] The rotating blade 14 has a shroud 15 on its top, which is fixedly connected to the bottom of the drone body 2. The airbag 46 is connected to the inside of the slider 32 via a control valve. The shroud 15 on the top of the rotating blade 14 is fixed to the bottom of the drone body 2, which not only protects the outside of the rotating blade 14 but also allows only the bottom of the rotating blade 14 to be exposed. This ensures that the rotating blade 14 stably receives airflow from the same direction and rotates in a fixed direction under the push of the airflow, effectively preventing the rotating blade 14 from failing to rotate normally due to interference from chaotic airflow. When the drone body 2 lands and the remote sensing device body 1 needs to be replaced, the control valve can be opened to allow the gas in the airbag 46 to enter the inside of the slider 32. The device pushes the card plate 33 to unlock it. If it does not need to be replaced, no operation is required. A buffer plate 16 is fixedly connected to the top of the card plate 33. The top of the buffer plate 16 has several sets of shock-absorbing holes. The buffer plate 16 on the top of the card plate 33 can play an elastic buffering role when the positioning block 34 is connected to the card plate 33. At the same time, the several sets of shock-absorbing holes on the buffer plate 16 can disperse vibration energy. When the vibration is transmitted to the buffer plate 16 through the card plate 33, the shock-absorbing holes will decompose the vibration energy into different areas, so that the vibration is further weakened before it is transmitted to the positioning plate. Combined with the elastic connection of the card plate 33 itself, the impact of vibration on the internal components of the remote sensing device body 1 is reduced, and the service life of the equipment is extended.

[0035] Working principle: First, the device is installed. The positioning block 34 on the top of the remote sensing device body 1 is aligned with the bottom of the clamping plate 33. The bottom of the clamping plate 33 is set at an inclination. When the positioning block 34 is pushed upward, it will squeeze the clamping plate 33, causing it to compress the inner spring and retract into the slider 32. After the positioning block 34 is completely inserted into the space between the clamping plate 33 and the slider 32, the clamping plate 33 clamps and fixes the positioning block 34 under the action of spring reset. At the same time, the guide rod 7 on the top of the positioning block 34 will slide into the limiting post 8 fixed at the bottom of the UAV body 2. The support ring 9 inside the limiting post 8 is connected to the bottom of the guide rod 7 through the spring elastic connection, completing the installation and positioning of the remote sensing device body 1. At this time, the damping spring 35 on the top of the slider 32 is in the initial extension state.

[0036] When in use, when the UAV body 2 carries the remote sensing device body 1 to carry out urban climate change monitoring operations, the vibration of the UAV body 2 caused by complex airflow will first be transmitted to the bottom fixed frame 31. The slider 32 on the inner side of the fixed frame 31 will slide along the inner wall of the fixed frame 31. The damping spring 35 on the top of the slider 32 will expand and contract with the sliding, and use the damping effect to initially absorb the vibration energy and reduce the vibration from being transmitted downward. At the same time, the remote sensing device body 1 is connected to the card plate 33 on the inner side of the slider 32 through the positioning block 34. The card plate 33 is elastically connected to the slider 32 through the spring. When the vibration is transmitted to the card plate 33, the spring of the card plate 33 will further expand and contract to achieve secondary buffering. In addition, the buffer plate 16 on the top of the card plate 33 and several sets of shock-absorbing holes on the plate will disperse the vibration energy, preventing the vibration from being concentrated and transmitted to the positioning block 34 and the remote sensing device body 1, thus protecting the internal components of the remote sensing device body 1.

[0037] As the drone body 2 continues to fly, airflow enters the interior of the movable ring 41 through the air inlet 42 on the front of the movable ring 41. The airflow outside the movable ring 41 drives the rotating blade 14 fixed to the outside of the connecting post 43 to rotate. The rotating blade 14 drives the connecting post 43 to rotate, improving transmission stability during use. The airflow entering the movable ring 41 directly acts on several sets of sealing plates 44 elastically connected by springs on the outside of the connecting post 43. Under the action of the springs, the sealing plates 44, pressed tightly against the inner wall of the movable ring 41, begin to rotate due to the airflow. This rotation, combined with the rotation of the connecting post 43, pushes the airflow towards the outlet of the movable ring 41. During this process, the elastic pawl 10 movably connected to one side of the connecting post 43 interacts with the pawl fixed inside the movable ring 41. The wheels 11 mesh with each other, and the elastic pawl 10 always sticks to the tooth surface of the ratchet 11 under its own elasticity, which restricts the connecting column 43 to rotate only in the direction of airflow. This prevents the connecting column 43 from rotating in the opposite direction due to unstable airflow and thus failing to effectively collect airflow. At the same time, the sealing block 5, which is elastically connected by a spring inside the movable ring 41, sticks to the inner wall of the movable ring 41 and blocks the airflow pushed by the sealing plate 44 to the air outlet side of the movable ring 41. As the sealing plate 44 continues to rotate, the pushing block 6 fixed on one side of it will contact the inclined side of the sealing block 5 and push the sealing block 5 to compress the spring away from the inner wall of the movable ring 41, so that the airflow can smoothly pass through the air outlet of the movable ring 41 into the hose, and then flow into the storage tank 45 for storage through the hose in one direction.

[0038] The gas stored in the gas tank 45 enters the air bladder 46, which is fixedly connected to the inside of the fixed frame 31 and located on top of the positioning block 34, through a one-way channel. This causes the air bladder 46 to inflate, and the inflated air bladder 46 applies a stable pressure to the top of the positioning block 34. This pressure, combined with the damping spring 35 and the spring of the clamping plate 33, further weakens the vibration. When the air bladder 46 experiences a sudden pressure surge due to vibration, causing the internal air pressure to become too high, the air pressure valve 47 connected to one side of the air bladder 46 will open in time to release some gas, eliminating the strong pressure vibration and preventing the air bladder 46 from being damaged due to overpressure. The air plate 12, which is fixedly connected to the bottom of the air bladder 46, is also connected to the air bladder 46. The air plate 12 contains a fixed honeycomb partition. Not only can it evenly distribute the gas to all areas of the air plate 12, keeping the pressure of the air plate 12 on the top of the positioning block 34 uniform and avoiding additional shaking caused by uneven force on the positioning block 34 due to excessive local pressure, but it can also divide the internal space of the air plate 12 into intervals. When subjected to vibration, the honeycomb partition will block the rapid flow of gas in the air plate 12, causing the gas to generate a damping effect during the flow. This damping effect can further absorb and weaken the vibration force transmitted to the air plate 12. Combined with the pressure buffering effect of the airbag 46, it forms a more comprehensive shock absorption effect, thereby further improving the stability of the remote sensing device body 1 in monitoring operations.

[0039] In addition, the air tank 45 is connected to a cleaning nozzle 13 fixedly connected to the bottom of the UAV body 2 via a hose. As the air pressure inside the air tank 45 increases, the cleaning nozzle 13 can automatically start when the air pressure reaches a certain level, using the gas stored in the air tank 45 to blow air and clean the surface of the remote sensing device body 1, removing dust and impurities attached to the surface. The cover 15 fixedly connected to the bottom of the UAV body 2 at the top of the rotating blade 14 not only protects the outside of the rotating blade 14, but also allows only the bottom of the rotating blade 14 to be exposed, ensuring that the rotating blade 14 stably receives airflow in the same direction and rotates in a fixed direction, avoiding the rotating blade 14 from being unable to rotate normally due to interference from chaotic airflow. When it is necessary to replace the remote sensing device body 1, the control valve connecting the airbag 46 and the slider 32 can be opened to allow the gas in the airbag 46 to enter the slider 32 and push the locking plate 33 to retract, releasing the locking plate 33 from fixing the positioning block 34. Then, the remote sensing device body 1 can be pulled down to complete the disassembly and replacement.

[0040] 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 the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
