[0013] The preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0014] A portable bird nest removal tool for ultra-high voltage and extra-high voltage transmission towers, such as Figure 1-Figure 2 As shown, it includes a main rod 9, the upper end of the main rod 9 is connected to the fixed plate 1 and the second curved plate 5, the arc direction of the second curved plate 5 is upward, the upper part of the main rod 9 is installed with a rotating plate 3, the middle part of the rotating plate 3 is connected to the main rod 9 through a rotating shaft, and the rotating plate 3 can rotate freely. One side of the rotating plate 3 is connected to a tension spring 2, one end of the tension spring 2 is connected to the fixed plate 1, and the other side of the rotating plate 3 is connected to the first curved plate 4, and the arc direction of the first curved plate 4 is downward. A fishing reel 10 is installed at the lower part of the main rod 9, and the winding end of the fishing reel 10 is connected to a pull rope 13, and one end of the pull rope 13 is connected to the rotating plate 3.

[0015] The present invention utilizes the second curved plate 5 and the first curved plate 4 to form a clamping plate structure. In the process of clamping the bird's nest, a semi-closed circular plate surrounding structure can be formed, thereby making it more convenient to clamp the branches of the bird's nest, and effectively preventing the branches of the bird's nest from slipping off the first curved plate 4 or the second curved plate 5 during the clamping process, thereby improving the efficiency of bird's nest removal.

[0016] Scope of application, material selection and feasibility analysis for specific implementation: The samples we actually made use the drawings in the specification as drawings, and are implemented according to the proportions and matching methods of the various components in the drawings in the specification. The connections mentioned are common connection methods such as strong adhesive connection, welding, riveting, flange connection, and one-piece molding connection. In actual production, the corresponding connection method, thickness and strength of the connection point can be selected creatively according to the actual connection strength requirements. The user can operate the fishing reel 10 to drive the pull rope 13 to pull one side of the rotating plate 3, thereby realizing the operation of clamping the bird's nest by the second arc plate 5 and the first arc plate 4.

[0017] The second curved plate 5 and the first curved plate 4 can cooperate to form a semi-closed circular plate surrounding structure, and an auxiliary bird's nest picking device is installed on one side of the second curved plate 5 and the first curved plate 4, and the auxiliary bird's nest picking device includes a first clamping plate 6, one side of the first clamping plate 6 is connected to the second curved plate 5 or the first curved plate 4, and an elastic barb device is installed on the side of the first clamping plate 6, and the elastic barb device includes a barb rod 8 and a limiting plate 11, each barb rod 8 cooperates with a limiting plate 11, one end of the barb rod 8 is hinged to the first clamping plate 6, and the other end of the barb rod 8 is a pointed end, and a torsion spring 12 is installed on the side of the first clamping plate 6, one end of the torsion spring 12 is connected to the barb rod 8, and the other end of the torsion spring 12 is connected to the first clamping plate 6, and the torsion spring 12 can use elasticity to make the central axis of the barb rod 8 perpendicular to the plane where the first clamping plate 6 is located, and the limiting plate 11 cooperating with the barb rod 8 is located on the side of the barb rod 8 away from the semi-closed circular plate surrounding structure.

[0018] The auxiliary bird's nest picking device of the present invention can utilize the barbed rod 8 to be inserted into the inside of the bird's nest during the process of clamping the bird's nest, thereby greatly improving the matching strength between the clamping structure formed by the first arc plate 4 and the second arc plate 5 and the bird's nest, thereby effectively avoiding the bird's nest from easily slipping off the clamping structure. Compared with the method of opening a groove on the clamping plate to increase the friction force, the matching strength between the auxiliary bird's nest picking device and the bird's nest is higher. The barbed rod 8 of the present invention can rotate on the first clamping plate 6. When the bird's nest enters the opening formed by the two first clamping plates 6, the barbed rod 8 can rotate toward the semi-enclosed circular plate surrounding structure to avoid the barbed rod 8 from excessively hindering the bird's nest from entering the semi-enclosed circular plate surrounding structure. When the bird's nest slips off, the barbed rod 8 will be driven to rotate in the opposite direction, so that the barbed rod 8 is inserted into the inside of the bird's nest, thereby effectively avoiding the bird's nest from slipping off. The limit plate 11 of the present invention can keep the barbed rod 8 perpendicular to the plane where the first clamping plate 6 is located when the barbed rod 8 is inserted into the inside of the bird's nest, so that the barbed rod 8 is kept in a matching state with the bird's nest.

[0019] The main rod 9 is a hollow tubular structural rod.

[0020] The main rod 9 of the present invention is a hollow tubular structure rod, which can reduce the weight of the main rod 9.
