Description

Technical Field

[0001] The invention belongs to the technical field of power transmission line safety, and relates to a bird nest removal device, in particular to a bird nest removal device with a dropped object collection function. Background Art

[0002] In recent years, the power industry has developed rapidly, the number of transmission line towers has increased year by year, and the hidden dangers of bird damage have become more and more serious. The work of removing bird nests has become more important and frequent. Unlike the insulated conductors of 10kV lines, 35kV transmission lines use bare conductors. There is a risk of fallen branches touching the wires, and some lines are close to industrial areas. There are also some conductors such as iron wire in the bird nests. Once they fall on the wires and cause discharge, they will cause irreversible damage to the wires. If the branches are stably placed between the line conductors, it will also cause tripping accidents.

[0003] Insulated pull rods are generally used to remove bird nests from transmission towers, and the bird nest structure is dismantled using "up" shaped contacts. In order to ensure power reliability, bird nests are often removed without power outages. During the process of removing bird nests, if there are no safeguards, it is difficult to ensure that fallen branches do not touch the wires.

[0004] According to statistics, the number of times fallen branches hit the line is more than 3.24 times per 100. In this context, a new bird nest removal tool is needed to solve the hidden danger of falling branches hitting the line when removing bird nests and improve the stability of line operation. Summary of the invention

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0022] A bird nest removal device with a fallen object collection function, the innovation of which lies in: comprising an insulating rod, an umbrella assembly 3, a clamping assembly 1 and a handle 5, wherein the umbrella assembly is installed at the upper position of the insulating rod, the clamping assembly is installed at the top of the insulating rod, and a handle for driving the clamping assembly to open and close is provided at the bottom of the insulating rod.

[0023] Taking into account the different heights of transmission line towers, in order to maximize the scope of use of the new bird nest cleaning tool, the insulating rod is a structure formed by connecting an upper insulating sleeve 7, a middle insulating sleeve 6 and a lower insulating sleeve 4. The two ends of the middle insulating sleeve are respectively inserted into the upper insulating sleeve and the lower insulating sleeve. A telescopic locking buckle 2 is provided at the lower end of the upper insulating sleeve and the upper end of the lower insulating sleeve. The telescopic locking buckle is a prior art and will not be described here. The position adjustment of the middle insulating sleeve in the lower insulating sleeve and the position adjustment of the upper insulating sleeve on the middle insulating sleeve are achieved through the telescopic locking buckle. The maximum length in the extended state can reach 4200mm, and when shortened, it is 2625mm. The rod length can be extended or shortened according to the height of the bird nest. Compared with the insulating pull rod, the assembly process is eliminated, which improves convenience.

[0024] In order to prevent the bird's nest and other debris from falling during operation, the umbrella assembly can collect fallen objects after it is opened. The umbrella assembly includes an umbrella cover 13, an umbrella cover frame 12, a support frame 14, an upper umbrella hoop 15 and a lower umbrella hoop 16. The upper umbrella hoop is slidably sleeved on the upper end of the insulating rod, and the lower umbrella hoop is fixedly installed on the lower insulating rod of the upper umbrella hoop. The lower umbrella hoop is provided with an umbrella cover frame extending upward. The umbrella cover is provided on the outer wall of the umbrella cover frame, one end of the support frame is connected to the upper umbrella hoop, and the other end of the support frame is connected to the umbrella cover frame. The umbrella cover is made of transparent material, such as plastic. In order to take into account the convenience and safety of operation, after the umbrella assembly is opened, its maximum diameter is limited to 660mm. Under the premise of not affecting the line of sight, it can effectively prevent branches from causing harm to people and wires. The rod body is made of insulating material, which effectively avoids the risk of electric shock and protects the personal safety of operators.

[0025] The clamping assembly is a bionic crocodile mouth hook clamp made of stainless steel 304 material. By operating the handle at the tail of the insulating rod, the crocodile mouth hook clamp can stably clamp the bird's nest debris, and the bite force is firm and easy to operate. It includes a main upper jaw piece 11, a secondary upper jaw piece 9, a lower jaw piece 8 and a traction crank 10. The main upper jaw piece includes an integrally formed plug-in part and a secondary upper jaw piece connecting part. The plug-in part is fixedly inserted in the upper insulating sleeve. The secondary upper jaw piece is installed on the side of the secondary upper jaw piece connecting part of the main upper jaw piece through the cooperation of screws and nuts. The front end of the lower jaw piece is a hook-shaped structure, and the rear end of the lower jaw piece is provided with an upwardly protruding connection structure. The lower end of the connection structure is hinged on the main upper jaw piece. The lower jaw piece is hinged on the main upper jaw piece between the main upper jaw piece and the secondary upper jaw piece. The traction crank is also hinged on the lower jaw piece, and the tail end of the traction crank is connected to the handle through the upper insulating sleeve.

[0026] In order to facilitate the clamping of the bird's nest, anti-slip teeth are arranged on the opposite end surfaces of the auxiliary upper jaw piece and the lower jaw piece.

[0027] The handle includes an installation head, a fixed handle part and a movable handle part. The installation head is a sleeve structure with a large diameter at one end and a small diameter at the other end. The end with the large diameter is sleeved on the insulating sleeve, and the fixed handle part is fixedly installed on the outer wall of the end with the small diameter. The movable handle part is hinged on the inner side of the fixed handle part, and the tail end of the traction crank is hinged on the movable handle.

[0028] In order to deal with the risk of scattered branches hitting the wire when cleaning the bird's nest, the present invention designs an crocodile-mouth hook clip and an umbrella-type protective cover with the help of bionics and other methods, and manufactures a bird's nest removal device with an anti-fall structure, which makes targeted improvements to the existing pain points and improves safety and operability.

[0029] At present, the equipment has been equipped and used by the line operation and maintenance team. It has been used more than 200 times in Jinghai Company's power transmission 35kV line to clean bird nests, achieving the following results:

[0030] First, the average number of line collisions per 100 times was reduced from 3.78 times / 100 times in the previous year to 0.5 times / 100 times, reducing the probability of line collisions by 86.8%, effectively achieving a reduction in the number of line collisions;

[0031] Second, there were no power line tripping incidents caused by the removal of bird nests, which effectively improved the stability of line operation, ensured the reliability of power supply to the power grid, and brought significant economic and social benefits.
