Description

Technical Field

[0001] The present invention relates to the technical field of drone suspension, and in particular to a drone suspension-based anti-fall device. Background Art

[0002] The drone-mounted anti-fall device is a new safety device used in scenarios such as tower climbing and maintenance of power lines. It uses a drone equipped with a tower climbing protection bracket and a safety rope to fly to the top of the tower. It uses a gravity-locking mechanism and, with the assistance of real-time video transmission, allows the bracket to be installed and removed from the tower top.

[0003] When hanging the anti-fall device on the bottom of the drone, it is generally necessary to connect the hook at the bottom of the drone to the hanging rod at the top of the anti-fall device, and then place the anti-fall device on the tower where it needs to be installed during the flight of the drone. Since the anti-fall device hung on the bottom of the drone during flight will be affected by the flow resistance generated during flight and rotation of the drone, it is easy for the device to deviate from the center position of the drone as a whole. The installation of the anti-fall device is likely to cause it to shake, affecting the position accuracy during installation. At the same time, the shaking during the installation of the anti-fall device is also easily transmitted to the drone, which will also affect the stability of the drone during flight.

[0038] The present invention has the following beneficial effects:

[0039] 1. The present invention uses a fixing assembly and an anti-fall frame, and when the two hanging rods are opened to form a diamond structure between the fixing frame and the two hanging rods, the opening of the two hanging rods can limit the position stability of the anti-fall frame during flight and hovering installation, reducing the shaking of the anti-fall frame. The diamond structure formed can resist the airflow disturbance to which the anti-fall frame is subjected during flight when the anti-fall frame flies with the main body, thereby improving the stability of the anti-fall frame during flight and installation. At the same time, the diamond structure formed limits the shaking of the anti-fall frame during flight, thereby improving the stability of the position of the anti-fall frame during installation, improving the installation accuracy between the anti-fall frame and the cross arm, and reducing the shaking of the anti-fall frame transmitted to the main body, affecting the flight stability of the main body when flying or hovering and the accuracy of subsequent installation, thereby improving the installation efficiency of the anti-fall frame.

[0040] 2. The present invention uses the piston assembly and the covering assembly. When the piston frame absorbs the gas in the airbag bag through the hose, the airbag bag will gradually shrink due to the loss of internal gas and be covered on the surface of the hanging rod under the action of a number of particles inside the airbag bag, thereby limiting the stability of the hanging rod position. Since the main body will be in a suspended and slowly descending state when the anti-fall frame is installed with the cross arm, the stability of the anti-fall frame is driven by limiting the hanging rod, which can reduce the situation where the anti-fall frame is installed and is blown by downward airflow, and the hanging rod and the hook plate will shake or swing up and down under the influence of airflow. By covering and supporting the hanging rod, the position of the anti-fall frame during installation can be limited, making it in a vertical state while further enhancing the stability of the anti-fall frame during installation.

[0041] 3. The present invention uses a sliding component. When the two hanging rods approach each other when the rectangular plate drives the hook plate to slide, the protruding part of the airbag bag will further push the hanging rod to separate it from the hook plate. At the same time, this process is synchronized when the anti-fall frame is separated from the cross arm. The airbag bag can push the hanging rod so that the closed hanging rod can be located between the two hook plates, thereby reducing the difficulty of the two hanging rods in interlocking with the hook plates during the subsequent suspension when the anti-fall frame is separated from the cross arm due to the opening of the two hanging rods. The hook plate can be stably and accurately installed and separated from the hanging rod, while improving the accuracy of the installation and separation of the anti-fall frame and the device, thereby improving the efficiency of disassembly of the anti-fall frame.

[0042] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The piston assembly 22 is installed on the side wall of the flip assembly 21 .

[0068] Sliding assembly 31, the sliding assembly 31 is installed on the side wall of the rectangular plate 301;

[0069] The covering component 32 is installed on the side wall of the rectangular plate 301 .

[0070] The connecting assembly 11 includes a triangular limit frame 112 bolted to the bottom of the connecting rod 111, the top inner wall of the triangular limit frame 112 is fixedly connected to the electric telescopic rod 113, and the output end of the electric telescopic rod 113 is fixedly connected to a triangular bar;

[0071] The fixing assembly 12 includes a fixing frame 121 bolted to the inside of the triangular limiting frame 112. The fixing frame 121 is fixedly connected to the inside of the fixing frame 121 with two fixing plates 122. The two fixing plates 122 are symmetrically distributed with the triangular limiting frame 112 as the center.

[0072] A side wall of the fixing frame 121 close to the fixing plate 122 is fixedly connected to a limiting rod 123 , and a rectangular groove 124 is formed on the inner wall of the fixing frame 121 close to the fixing plate 122 ;

[0073] The front and back of the fixing frame 121 are both provided with two long slots, and the two long slots are symmetrically distributed with the triangular limit frame 112 as the center;

[0074] Two inclined grooves are provided on the front and back of the fixing frame 121, and the two inclined grooves are symmetrically distributed with the triangular limit frame 112 as the center. First, the fixing frame 121 is connected to the triangular limit frame 112, and then the triangular limit frame 112 is connected to the main body 1 through the connecting rod 111. Then, the anti-fall gear 4 or the two hanging rods 401 are hung on the hook plate 313, and the main body 1 is started. When the main body 1 is in flight, it will drive the anti-fall gear 4 to fly.

[0075] The L-plate 201 is slidably connected between the two long slots, and a rotating plate 211 is rotatably connected to one side of the L-plate 201 close to the middle of the fixed frame 121. A bending spring is fixedly connected to the top of the rotating plate 211, and one end of the bending spring away from the rotating plate 211 is fixedly connected to the L-plate 201. When the sliding plate 212 drives the movable plate 213 to slide downward, the side wall of the movable plate 213 will be restricted by the limiting rod 123, so that the movable plate 213 can drive the rectangular plate 301 to slide when it slides down. When the movable plate 213 drives the rectangular plate 301 to slide, the movable plate 213 and the rectangular plate 301 will gradually form a parallel state.

[0076] A sliding plate 212 is provided on the top of the L-plate 201. Two return springs are fixedly connected to the bottom inner wall of the sliding plate 212. The tops of the two return springs are fixedly connected to the fixed plate 122.

[0077] The top of the sliding plate 212 slides through the top of the fixed plate 122, and the top of the sliding plate 212 is rotatably connected to the movable plate 213. When the movable plate 213 rotates and drives the rectangular plate 301 to slide, the side wall of the movable plate 213 will always be in contact with the push rod 324.

[0078] The piston assembly 22 includes a piston rod 221 fixedly connected to the side wall of the sliding plate 212;

[0079] One end of the piston rod 221 away from the sliding plate 212 passes through the side wall of the rectangular groove 124 and extends to the outside. The extended end of the piston rod 221 is slidably connected to the piston frame 222. The top of the piston frame 222 is fixedly connected to the hose.

[0080] The end of the hose away from the piston frame 222 passes through the interior of the fixed frame 121. When the sliding plate 212 slides downward, it will drive the piston rod 221 to slide downward in the piston frame 222. When the piston rod 221 slides downward, a certain negative pressure will be generated inside the piston frame 222 and the gas inside the airbag 322 will be absorbed through the hose.

[0081] The side wall of the rectangular plate 301 is rotatably connected to the movable plate 213;

[0082] The sliding assembly 31 includes a telescopic rod 311 rotatably connected to the side of the rectangular plate 301 close to the movable plate 213, and the top of the telescopic rod 311 is rotatably connected to the sliding plate 2 312;

[0083] The front and back sides of the sliding plate 2 312 are fixedly connected with sliders, which are slidably connected to the inside of the inclined groove;

[0084] The end of the sliding plate 2 312 away from the telescopic rod 311 is fixedly connected to the hook plate 313, and the hook plate 313 is in contact with the hanging rod 401. When the rectangular plate 301 slides, the telescopic rod 311 drives the sliding plate 2 312 and the hook plate 313 to slide synchronously along the guidance of the inclined groove on the inner wall of the fixed frame 121, driving the two hook plates 313 and the hanging rod 401 on the hook plate 313.

[0085] The covering assembly 32 includes a flip plate 321 rotatably connected to the side wall of the rectangular plate 301, and a guide groove is formed on a side of the flip plate 321 close to the rectangular plate 301;

[0086] An air bag 322 is fixedly connected to one side of the flip plate 321 away from the rectangular plate 301. A plurality of spherical particles are slidably connected to the interior of the air bag 322. The air bag 322 is connected to the piston frame 222 via a hose.

[0087] The guide groove is internally slidably connected to a connecting ear 323, and the side wall of the connecting ear 323 is rotatably connected to a push rod 324. The push rod 324 slides through the side wall of the rectangular plate 301 at one end away from the connecting ear 323. When the piston frame 222 absorbs the gas in the airbag bag 322 through the hose, the airbag bag 322 will gradually shrink due to the loss of internal gas and be coated on the surface of the hanging rod 401 under the action of several particles inside the airbag bag 322, thereby limiting the stability of the position of the hanging rod 401.

[0088] When in use, first connect the fixing frame 121 with the triangular limiting frame 112, and then connect the triangular limiting frame 112 with the main body 1 through the connecting rod 111, then hang the anti-fall frame 4 or the two hanging rods 401 on the hook plate 313, start the main body 1, and when the main body 1 is in flight, it will drive the anti-fall frame 4 to fly, and when it reaches the appropriate position at the top of the iron tower, the main body 1 will be lowered. When the main body 1 is descending, the anti-fall frame 4 will contact the crossarm on the iron tower. When the main body 1 continues to move downward, the anti-fall frame 4 can be installed on the crossarm, completing the suspension between the anti-fall frame 4 and the main body 1 and the installation purpose of the anti-fall frame 4.

[0089] When the two hook plates 313 drive the hanging rods 401 to slide, the two hanging rods 401 will form a diamond-shaped structure with the fixed frame 121 under the pull of the hook plates 313. When the two hanging rods 401 are opened, a diamond-shaped structure will be formed between the fixed frame 121 and the two hanging rods 401. When it is a diamond structure, it can also limit the stability of the position of the anti-drop gear 4 during flight and hovering installation by opening the two hanging rods 401, and reduce the shaking of the anti-drop gear 4. The diamond structure formed can resist the airflow disturbance to which the anti-drop gear 4 is subjected during flight when the anti-drop gear 4 flies with the main body 1, thereby improving the stability of the anti-drop gear 4 during flight and installation. At the same time, the diamond structure formed limits the shaking of the anti-drop gear 4 during flight, which can improve the stability of the position of the anti-drop gear 4 during installation, improve the installation accuracy between the anti-drop gear 4 and the cross arm, and reduce the shaking of the anti-drop gear 4 transmitted to the main body 1 to affect the flight stability of the main body 1 during flight or hovering and the accuracy of subsequent installation, thereby improving the installation efficiency of the anti-drop gear 4.

[0090] When the movable plate 213 is rotated and the rectangular plate 301 is driven to slide, the side wall of the movable plate 213 will be restricted by the limit rod 123, so that the movable plate 213 can drive the rectangular plate 301 to slide when it slides down. When the movable plate 213 drives the rectangular plate 301 to slide, the movable plate 213 and the rectangular plate 301 will gradually form a parallel state. At this time, the movable plate 213 will rotate and drive the rectangular plate 301 to slide, and the side wall of the movable plate 213 will always contact the pushing rod 324. Then, when the movable plate 213 rotates, the pushing rod 324 will push the flip plate 321 and the air bag 322 to contact the side wall of the hanging rod 401. At the same time, when the sliding plate 212 slides downward, it will drive the piston rod 221 to slide downward in the piston frame 222. When the piston rod 221 slides downward, a certain negative pressure is generated inside the piston frame 222 and the gas inside the air bag 322 is sucked out through the hose. When there are several spherical particles and the side wall of the airbag bag 322 is in close contact with the hanging rod 401, when the piston frame 222 absorbs the gas in the airbag bag 322 through the hose, the airbag bag 322 will gradually shrink due to the loss of internal gas and be coated on the surface of the hanging rod 401 under the action of several particles inside the airbag bag 322, thereby limiting the stability of the hanging rod 401 in the position. Since the main body 1 will be in a hovering and slowly descending state when the anti-fall frame 4 is installed with the crossarm, by limiting the stability of the anti-fall frame 4 driven by the hanging rod 401, it can reduce the situation where the anti-fall frame 4 is installed and is blown by the downward airflow, and the hanging rod 401 will produce up and down shaking or swinging between the hook plate 313 and the hook plate 313 under the influence of the airflow. By covering and supporting the hanging rod 401, the position of the anti-fall frame 4 during installation can be limited, making it in a vertical state while further enhancing the stability of the anti-fall frame 4 during installation.

[0091] When the anti-fall frame 4 needs to be separated from the fixed frame 121, it is only necessary to drive the fixed frame 121 to slide downward on the top of the two hanging rods 401 through the main body 1. At this time, the hanging rod 401 will push the rotating plate 211 and enter between the rotating plate 211 and the fixed frame 121. Then, when the main body 1 continues to drive the fixed frame 121 to slide downward, the L plate 201 will contact the side wall of the cross arm. Then, when the main body 1 pushes the fixed frame 121 to continue to move downward, the L plate 201 will be subjected to the reaction force of the cross arm and slide upward inside the sliding groove. When the L plate 201 slides upward, it will push the sliding plate 212 to slide upward. When the sliding plate 212 slides upward, it will push the rectangular plate 301 to reset through the movable plate 213, presenting a Figure 7In the middle state, when the movable plate 213 pushes the rectangular plate 301 to reset, the rectangular plate 301 will be restricted by the sliding plate 2 312 after rotating a certain angle and will be in an approximately vertical state. Then, when the movable plate 213 continues to push the rectangular plate 301, the sliding of the rectangular plate 301 will drive the curved hook plate 313 to slide synchronously, so that the two hanging rods 401 are close to each other. At the same time, since the side wall of the airbag bag 322 protrudes more than the curved hook plate 313, when the two hanging rods 401 are close to each other when the rectangular plate 301 drives the curved hook plate 313 to slide, the protruding part of the airbag bag 322 will further push the hanging rod 401 separates it from the hook plate 313. At the same time, this process is synchronized when the anti-fall frame 4 is separated from the cross arm. The air bag 322 can push the hanging rod 401, so that the closed hanging rod 401 is between the two hook plates 313, reducing the difficulty of the two hanging rods 401 in hanging when the anti-fall frame 4 is separated from the cross arm due to the opening of the two hanging rods 401. The hook plate 313 can be stably and accurately installed and separated from the hanging rod 401, while improving the accuracy of installation and separation of the anti-fall frame 4 and this device, and improving the disassembly efficiency of the anti-fall frame 4.

[0092] When the two hanging rods 401 on the anti-fall frame 4 need to be placed between the two hook plates 313, the electric telescopic rod 113 is started. When the electric telescopic rod 113 works, it squeezes the gap between the two hanging rods 401 through the triangular bar so that the two hanging rods 401 are separated from each other and hung on the hook plates 313. Then, when the main body 1 is flying, the hook plates 313 and the hanging rods 401 can be engaged to complete the suspension work.
