Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a distribution box with a bird-proof plate. Background Art

[0002] The distribution box is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. In normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of failure or abnormal operation, the circuit is cut off or an alarm is given with the help of protective electrical appliances. In addition, the measuring instruments installed in the distribution box can display various parameters in operation, adjust certain electrical parameters, and give prompts or signals for deviations from normal working conditions. Existing distribution boxes are often used in various power generation, distribution, and substations or in outdoor environments.

[0003] Due to the low frequency of human activities near the distribution boxes, wild animals, especially birds, often stay on the distribution boxes. The hazards caused by the power system, such as nesting and corrosion caused by excrement, affect the safe operation of power transmission and distribution equipment all year round.

[0004] There are various bird-proofing devices in the prior art, such as an outdoor cable branch box authorized by China Patent Authorization Announcement No.: CN214506449 U on October 26, 2021, including a box body and a protective cover arranged on the upper part of the box body, a bird-repelling device is arranged on the top of the protective cover, rain and snow sensors and solar panels are arranged on the two sides of the protective cover, a motor is arranged on the outer top surface of the box body, a battery is arranged on the outer top surface of the box body on one side of the motor, a fireproof partition is arranged on the inner side of the box body, an induction lamp is arranged on the inner top surface of the box body, a suspended hexafluoropropane automatic fire extinguishing device is arranged on the inner top surface of the box body on one side of the induction lamp, a cooling fan is arranged on one side of the inner bottom surface of the box body, a horizontal ion fan is arranged at one end of the inner bottom surface of the box body, and an intelligent dehumidification device is arranged at the other end of the inner bottom surface of the box body.

[0005] This prior art proves that the bird-repelling effect can be effectively achieved through the movement of the thorn-like protrusions, but its movement requires additional power input and can only achieve the bird-repelling effect through motor control. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to:

[0007] 1. Provide a bird-proof board, which can achieve the effect of bird-repelling by motion without installing an additional motor in a general distribution box.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a distribution box with a bird-proof board, comprising a distribution box body and a bird-proof board, a top cover is arranged on the top of the distribution box body, a fulcrum is arranged on the top cover, the bird-proof board is rotatably connected to the top of the top cover through the fulcrum, the horizontal height of the center of gravity of the bird-proof board is lower than the horizontal height of the fulcrum, the top view orthographic projection of the bird-proof board covers the top cover, the connection between the bird-proof board and the fulcrum is located in the middle of the bird-proof board, and a shaking gap is arranged between the bird-proof board and the top cover.

[0009] This solution adopts the design of a shaking bird-proof board. After it is installed on the top cover, when a bird lands on the bird-proof board, it will shake due to the loss of balance, and one end will fall until it collides with the top cover, so that the bird is frightened and flies away from the bird-proof board to achieve the effect of bird repelling.

[0010] Optionally, a plurality of thorn-like protrusions are further provided on the upper end surface of the bird-proof plate.

[0011] Optionally, the top height of the thorn-shaped protrusion on the middle part of the upper end surface of the bird-proof plate is higher than the top heights of the other thorn-shaped protrusions.

[0012] Optionally, the bird-proof plate is a plate-like structure with a middle portion protruding upward and two ends slanting downward.

[0013] Optionally, a cavity is provided in the bird-proof plate.

[0014] The design of the cavity is mainly used to reduce the weight of the bird-proof board, so that it is easier for the bird-proof board to shake when lighter birds land on the bird-proof board.

[0015] Optionally, the fulcrum is a hollow circular tube, and an arc-shaped groove corresponding to the outer surface of the hollow circular tube is provided on the middle part of the lower end of the bird-proof plate.

[0016] The bird-proof board in this solution is placed on the hollow circular tube completely by its own weight. The advantage is that it is more sensitive to the extra weight attached to the bird-proof board. After the birds land on the bird-proof board, they will be driven away more quickly by the impact caused by the shaking.

[0017] Optionally, the fulcrum is composed of several sections of hollow circular tubes, and several sliding gaps are arranged between the several hollow circular tubes. A sliding ring corresponding to the sliding gap is arranged on the middle part of the lower end of the bird-proof plate, and the inner diameter of the sliding ring is consistent with the inner diameter of the hollow circular tube. A positioning shaft passes through the hollow circular tube and the sliding ring alternately in sequence.

[0018] The bird-proof board in this solution is installed on the top plate through a commonly designed hinged structure. The advantage is that the connection structure is stable and it is not easy for the bird-proof board to fall off due to external forces.

[0019] The utility model has the beneficial technical effect that: the design of the bird-proof board can be shaken. After it is installed on the top cover, when a bird lands on the bird-proof board, it will shake due to the loss of balance, and one end will fall until it collides with the top cover, so that the bird is frightened and flies away from the bird-proof board to achieve the effect of driving away the bird.
