A power crossarm shielding device

Abstract

This utility model discloses a power crossarm shielding device, including a left insulating baffle, a right insulating baffle, a utility pole, and an angle iron crossarm installed on the utility pole. The left and right insulating baffles are connected by a bolt assembly to a connecting flange. The connecting flange is detachably connected to a fixed insulating tube. An angle iron clamp is installed at the end of the fixed insulating tube, and a limiting component is provided at the opening of the angle iron clamp. After the angle iron crossarm is fully inserted into the angle iron clamp, rotating the handle will cause the limiting baffle to be rotated 180° around the axis of the operating rod. At this time, the angle iron crossarm is sealed inside the angle iron clamp and cannot slide out. The installation of the insulating plate can be completed quickly. It is lightweight, structurally stable, and provides safe insulation. It is also convenient to assemble and disassemble, highly efficient, and low in cost.

Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for live-line work, and in particular to a power crossarm shielding device. Background Technology

[0002] With the growing acceptance of the concept that "uninterrupted power supply is the best service," the maintenance of 10kV power lines requires live-line work. Workers are positioned inside the insulated bucket of a boom truck, using insulated gloves to perform maintenance at close range. To ensure the safety of these workers, it is necessary to safely isolate any live parts on the crossarms.

[0003] The current method of using insulating cloth to cover the crossarm is complicated, with both wrapping and removal taking more than 15 minutes, which reduces maintenance efficiency and wastes valuable time for live-line workers. At the same time, directly wrapping the angle iron crossarm with insulating cloth makes it easy to wear and tear, thus shortening the service life of the insulating cloth and increasing the procurement cost of maintenance equipment. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a power crossarm shielding device. This device features a convenient assembly and disassembly structure, effectively and safely isolating live parts on the crossarm while solving the problems of low efficiency and high cost in existing solutions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A power crossarm shielding device includes a left insulating baffle, a right insulating baffle, a power pole, and an angle iron crossarm mounted on the power pole. The left and right insulating baffles are connected to a connecting flange by a bolt assembly. The connecting flange is detachably connected to a fixed insulating round tube. An angle iron clamp is installed at the end of the fixed insulating round tube, and a limiting component is provided at the opening of the angle iron clamp.

[0006] Preferably, the limiting component includes a connecting rod that rotates inside the fixed insulating round tube, with a limiting baffle connected to one end of the connecting rod near the angle iron clamp, and a rotating handle installed at the other end.

[0007] Preferably, the connecting flange is threaded with screws, which abut against the side wall of the fixed insulating round tube.

[0008] Preferably, the left insulating baffle and the right insulating baffle are provided with stepped structures on their adjacent sides, and the two stepped structures overlap.

[0009] Preferably, both the left and right insulating baffles are provided with observation windows.

[0010] Compared with the prior art, the beneficial effects of this utility model are: after the angle iron crossarm is fully inserted into the angle iron clamp, the handle is rotated so that the limiting baffle is in the position of rotating 180° around the axis of the operating rod. At this time, the angle iron crossarm is sealed inside the angle iron clamp and cannot slide out, which can quickly complete the installation of the insulation board. It is lightweight, structurally stable, and has safe insulation. At the same time, it is convenient to disassemble and assemble, highly efficient, and low in cost. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5 A power crossarm shielding device includes a left insulating baffle 1, a right insulating baffle 2, a power pole, and an angle iron crossarm 11 installed on the power pole. The left insulating baffle 1 and the right insulating baffle 2 are connected to a connecting flange 4 by a bolt assembly 9. The connecting flange 4 is detachably connected to a fixed insulating round tube 5. An angle iron clamp 7 is installed at the end of the fixed insulating round tube 5, and a limiting component is provided at the opening of the angle iron clamp 7.

[0016] The left insulating baffle 1 and the right insulating baffle 2 are set perpendicular to the fixed insulating round tube 5.

[0017] In this embodiment, the limiting component includes a connecting rod that rotates to be connected inside the fixed insulating round tube 5. One end of the connecting rod near the angle iron clamp 7 is connected to a limiting baffle 8, and the other end is equipped with a rotating handle 6.

[0018] By rotating the handle 6, the limit baffle 8 is driven by the connecting rod to rotate around the fixed insulating round tube 5 and the axis. When the angle iron crossarm 11 is fully inserted into the angle iron clamp 7, the handle 6 is rotated so that the limit baffle 8 is in the position of rotating 180° around the axis of the operating rod. At this time, the angle iron crossarm 11 is sealed inside the angle iron clamp 7 and cannot slide out.

[0019] In this embodiment, a screw 10 is threaded onto the connecting flange 4, and the screw 10 abuts against the side wall of the fixed insulating round tube 5.

[0020] In this embodiment, the left insulating baffle 1 and the right insulating baffle 2 are provided with stepped structures on their adjacent sides. The two stepped structures overlap and intersect, effectively sealing the joint when the left insulating baffle 1 and the right insulating baffle 2 are joined.

[0021] In this embodiment, both the left insulating baffle 1 and the right insulating baffle 2 are provided with observation windows 3, which are made of transparent insulating plates. The installation of the angle iron clamp 7 on the angle iron crossarm 11 can be observed through the observation windows 6.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
