Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power operation and maintenance equipment, in particular to a foldable airborne bird nest cleaner. BACKGROUND

[0002] With the increasing emphasis on ecological environment protection, the natural ecological environment has been effectively restored, the living habitat of birds has expanded, and the activities of birds have become more frequent. Under this background, bird damage has gradually become the primary hidden danger affecting the safe operation of overhead transmission lines.

[0003] After long-term research and observation, it is found that there are bird nests on all transmission towers that have experienced bird damage. These bird nests not only may cause line short circuit due to the falling of nesting materials such as branches and dry grass, but also may cause tripping and other faults due to the touching of conductors during the activities of birds, which seriously threatens the normal power supply of transmission lines.

[0004] However, there is no bird prevention device for actively removing bird nests in the current power operation and maintenance field. The existing bird prevention measures are mostly passive protection, such as installing bird prevention spikes and bird prevention baffles, which can only prevent birds from nesting in certain positions of the tower to a certain extent, and cannot effectively remove the formed bird nests.

[0005] Traditional bird nest removal operations mainly rely on manual tower climbing, and the operator needs to carry tools to climb to the bird nest position of the tower, which not only has low operation efficiency, but also often takes several hours for a single removal operation, and there are safety risks such as high-altitude falling and electric shock. At the same time, manual tower climbing removal operation needs to be included in the power operation plan in advance, which occupies the line outage time and affects the power supply reliability.

[0006] In recent years, the application of unmanned aerial vehicle technology in the field of power transmission has become more and more widespread, and it has the advantages of flexibility, efficiency and safety, and can complete various inspection and observation tasks without power outage and personnel climbing. Therefore, it is urgent to develop an airborne bird nest cleaner, which is carried on an unmanned aerial vehicle to achieve efficient and safe bird nest removal in a short time without tower climbing operation and planned arrangement, to eliminate bird damage from the root and fill the gap in the existing technology. SUMMARY

[0007] The purpose of the present application is to provide a foldable airborne bird nest cleaner, which solves the problems of poor effect of existing passive bird prevention measures, low efficiency and high safety risk of traditional manual tower climbing removal, realizes efficient and safe bird nest removal operation, adapts to mainstream large unmanned aerial vehicles such as DJI M300, meets the urgent needs of the power operation and maintenance field for bird nest removal, and solves the technical problems in the background art.

The top plate and the annular plates below are fixedly connected together in the vertical direction with a spacing by long bolts passing through the mounting holes in sequence, forming a multi-layer frame structure with an open lower part.

[0010] Further, guide sleeves are provided on the annular plates and the top plate, which are matched with the positions of the mounting holes. The number of guide sleeves is the same as that of the mounting holes. The guide sleeves are used to guide the long bolts to pass through and equally space the adjacent annular plates.

[0011] Further, a first hinged end is provided on the outer circumference of each annular plate. The positions of the first hinged ends of each annular plate are different. From top to bottom, the positions of the first hinged ends are arranged in a clockwise rotation of 45 degrees around the center link.

[0012] Further, the transmission part includes a driving arm and a multi-layer stepped driven arm. The driving arm includes a hinged end and a moving end. The end close to the center link is the hinged end. A shaft sleeve is provided on the hinged end, and a bearing is arranged inside.

The driving arm drives the multi-layer stepped driven arm to rotate around the center link. A connecting plate is provided on the moving end of the driving arm. The connecting plate is connected with the multi-layer stepped driven arm.

[0013] Further, the multi-layer stepped driven arm includes a plurality of sequentially connected and fixed arc-shaped plates. The thickness and curvature of the arc-shaped plates are the same as those of the annular plates. The plurality of sequentially connected and fixed arc-shaped plates form a spiral descending stepped structure. The setting heights of the arc-shaped plates and the annular plates of the same layer are the same. A second hinged end is provided on the left end of each arc-shaped plate.

[0014] Furthermore, there are multiple folding structures; each multi-layered fixing frame is equipped with a folding structure; the two ends of the folding structure are respectively hinged to the annular plate and the arc-shaped plate at the first hinge end and the second hinge end. The folded structure consists of two curved rods hinged together; the curvature and thickness of the curved rods are the same as those of the annular plate.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] To achieve the above objectives, the present invention provides the following technical solutions, such as... Figures 1-8 As shown, an airborne folding bird nest remover includes a geared motor 1, a fixing part 2, a transmission part 3, and a folding structure 4; The fixing part 2 serves as the basic support structure of the entire cleaner, used to connect the drone and provide a mounting base for the geared motor 1 and the folding structure 4. It includes a central connecting rod 21 and a multi-layer fixing frame 22. The upper end of the central connecting rod 21 is fixedly connected to the drone, and its lower end is fixedly connected to the top of the multi-layer fixing frame 22. The geared motor 1 is connected to the UAV via a connecting cable and is fixedly mounted on the fixed part 2 via a mounting bracket; the two ends of the folding structure 4 are respectively hinged to the multi-layer fixed frame 22 and the transmission part 3; The geared motor 1 drives the transmission part 3 to rotate around the central connecting rod 21; the transmission part 3 drives the folding structure 4 to expand outward or contract inward.

[0024] Further, the multi-layer fixing frame 22 has nine layers in total; it is composed of eight annular plates 221 and a top plate 222 on the topmost layer; the center of the top plate 222 is connected to the lower end of the center connecting rod 21 through a bolt; the annular plates 221 and the top plate 222 are both provided with matching mounting holes 223, and there are eight mounting holes 223, which are evenly distributed in a circle on the annular plates 221 and the top plate 222. The top plate 222 and the eight annular plates 221 below it are fixed and connected together in the vertical direction with a gap through long bolts 224 successively penetrating the mounting holes 223, forming a multi-layer frame structure with an open lower part.

[0025] Further, the single annular plate 221 and the top plate 222 are provided with guide sleeves 225, which match the positions of the mounting holes 223; there are eight guide sleeves 225 and eight mounting holes 223; the guide sleeves 225 are used to guide the long bolts 224 to pass through, and because the heights of the guide sleeves 225 are consistent, they can equally space the adjacent annular plates 221. This can ensure that the spacing between the adjacent annular plates 221 is uniform, ensuring the stability and consistency of the structure of the multi-layer fixing frame 22.

[0026] Further, the outer circumference of each annular plate 221 is provided with a first hinge end 226, which is used for hinge connection with the folding structure 4. From top to bottom, the positions of the first hinge ends 226 on each annular plate 221 rotate 45 degrees clockwise around the center connecting rod 21. This staggered distribution design can ensure that the folding structure 4 does not interfere with each other during the unfolding and shrinking process, and at the same time, it can make the unfolded cleaner structure more uniform and the stress more stable.

[0027] Further, the transmission part 3 is used to transmit power from the reduction motor 1 to the folding structure 4, driving the folding structure 4 to move. The transmission part 3 includes a driving arm 31 and a multi-layer stepped driven arm 32. The driving arm 31 is connected to the reduction motor 1 through a gear transmission. The reduction motor 1 is fixed on a mounting seat, and the mounting seat is fixed on the center connecting rod 21. The reduction motor 1 drives the driving arm 31 to rotate. The driving arm 31 drives the multi-layer stepped driven arm 32 to rotate around the center connecting rod 21. Specifically, the driving arm 31 includes a hinge end and a moving end. The end close to the center connecting rod 21 is the hinge end. The hinge end is provided with a shaft sleeve, and the inside of the shaft sleeve is provided with a bearing 311. Through the bearing 311, the driving arm 31 has the freedom to rotate around the center connecting rod 21. A driven gear 313 is fixed coaxially outside the shaft sleeve. The transmission shaft of the reduction motor 1 is connected to a driving gear 312, and the driving gear 312 is engaged with the driven gear 313. When the reduction motor 1 starts, the driving gear 312 rotates, driving the driven gear 313 to rotate, and then driving the driving arm 31 to rotate around the center connecting rod 21.

[0028] The moving end of the active arm 31 is provided with a connecting plate 314; the connecting plate 314 is connected with the multilayer stepped driven arm 32, so as to realize the synchronous movement of the active arm 31 and the multilayer stepped driven arm 32.

[0029] Further, the multilayer stepped driven arm 32 comprises eight arc-shaped plates 321 which are sequentially connected and fixed; the thickness and the curvature of the arc-shaped plates 321 are the same as the thickness and the curvature of the annular plates 221; the eight arc-shaped plates 321 form a spiral eight-layer descending stepped structure; the arc-shaped plates 321 and the annular plates 221 of the same layer have the same setting height. The left end of each arc-shaped plate 321 is provided with a second hinge end 322; the two ends of the folding structure 4 are respectively hinged with the annular plates 221 and the arc-shaped plates 321 at the first hinge end 226 and the second hinge end 322.

[0030] Further, the folding structure 4 is used for directly contacting the bird nest, so as to complete the opening, disintegration or complete taking of the bird nest. There are eight folding structures 4; each multilayer fixed frame 22 is provided with one folding structure 4; the two ends of the folding structure 4 are respectively hinged with the annular plates 221 and the arc-shaped plates 321 at the first hinge end 226 and the second hinge end 322. The folding structure 4 comprises two arc-shaped rods 41 which are hinged together; the curvature and the thickness of the arc-shaped rods 41 are the same as the curvature and the thickness of the annular plates 221. Specifically, since the two ends of the folding structure 4 are respectively hinged with the annular plates 221 and the arc-shaped plates 321 at the first hinge end 226 and the second hinge end 322, that is, the two ends of the folding structure 4 are respectively hinged with the multilayer fixed frame 22 and the multilayer stepped driven arm 32; since the multilayer fixed frame 22 is fixedly connected with the unmanned aerial vehicle as a fixed structure, and the multilayer stepped driven arm 32 is a moving end, under the driving of the multilayer stepped driven arm 32, the folding structure 4 is deformed under the driving of the multilayer stepped driven arm 32; the folding structure 4 performs expansion or contraction movement. The whole device is expanded into a flower-like structure when opened, and is restored into a multilayer cylindrical structure when retracted. Further, the curvature and thickness of the arc-shaped rods 41 are the same as those of the annular plate 221, and the arc-shaped rods 41 have arc-shaped hollows in the middle; under the premise of ensuring the structural strength, the weight of the arc-shaped rods 41 is reduced, and the load pressure of the unmanned aerial vehicle is reduced. The radius of a single arc-shaped rod 41 is 150 mm, and the thickness is 6 mm; the spacing between the upper and lower adjacent arc-shaped rods 41 is 15 mm; when not working, the folding structure 4 is in a contracted state, facilitating the carrying and transportation of the unmanned aerial vehicle; when working, the folding structure 4 can be unfolded along the radial direction of the center connecting rod 21 under the driving of the transmission part 3, and the unfolded diameter can be adjusted within the range of 150-300 mm, which can adapt to most power transmission tower bird nests, such as magpie nests and crow nests. The arc-shaped rods 41 are made of 6061 aluminum alloy material, and the surface is treated by anodic oxidation and sand blasting bright silver. The working surface of a single arc-shaped rod 41 is uniformly arranged with fine steel sand with a particle size of 0.5-1 mm, and the fine steel sand is fixed by epoxy resin glue, and the coverage rate is greater than or equal to 80%.

[0031] The working principle and process are as follows: When the bird nest cleaning operation is needed, the speed reducer motor 1 is started, the speed reducer motor 1 drives the driving arm 31 to rotate around the center connecting rod 21 through the meshing transmission of the driving gear 312 and the driven gear 313. In the rotating process of the driving arm 31, the multilayer stepped driven arm 32 is driven to rotate around the multilayer fixed frame 22 through the connecting plate 314. Since the two ends of the folding structure 4 are hinged to the multilayer fixed frame 22 and the multilayer stepped driven arm 32 respectively, the rotation of the multilayer stepped driven arm 32 will cause the folding structure 4 to deform.

[0032] When the multilayer stepped driven arm 32 rotates away from the center connecting rod 21, the folding structure 4 expands outward, the whole cleaner expands into a flower-like structure, the arc-shaped rods 41 are embedded in the bird nest, the bird nest structure is expanded by the radial force, and the nest-building materials such as branches and hay are shed until the bird nest is disintegrated; when the multilayer stepped driven arm 32 rotates towards the center connecting rod 21, the folding structure 4 shrinks inward, and the whole cleaner returns to a multilayer cylindrical structure, which is convenient for storage and carrying.

[0033] The present application has two operation modes, which can not only expand the folding structure 4 to expand the bird nest and disintegrate the bird nest to complete the regular bird nest cleaning, but also slowly insert the bird nest with the lowest force when encountering a situation with young birds or bird eggs, the folding structure 4 is expanded synchronously to fit the inner wall of the bird nest, the bird nest is completely translated to a preset collection point on the ground, and then the bird nest is released after shrinking, so as to ensure that the eggshell or young bird is not damaged, and the operation demand and ecological protection are considered.

[0034] The embodiments of the present application are presented by way of example and description, and are not intended to be exhaustive or to limit the application to the form disclosed. Many modifications and variations will be apparent to those skilled in the art. Embodiments are chosen and described in order to best explain the principles of the application and its practical application, and to thereby enable others skilled in the art to best utilize the application in various embodiments and with various modifications as are suited to the particular use contemplated.
