Description

Technical Field

[0001] This utility model relates to the field of insulator shielding covers, and in particular to a near-ground side-suspended insulator shielding cover for power distribution lines. Background Technology

[0002] Suspension insulators on the near-ground side of power distribution lines are widely used insulation devices in power systems. Their main function is to suspend overhead conductors and ensure effective insulation between the conductors and towers or other supporting structures. Suspension insulators typically consist of insulating components (such as porcelain or glass components) and metal fittings (such as steel feet, iron caps, and flanges), which are tightly joined together by adhesive bonding or mechanical clamping. The insulating components, as the core of the suspension insulator, are made of high-resistance insulating materials and possess excellent insulation performance. The metal fittings are used to connect the insulating components to the conductors and securely fix the insulator to the towers.

[0003] In the application of shielding covers for near-ground suspension insulators in power distribution lines, although the two-sided wedge-shaped cover design can effectively cover the insulator and improve operational convenience to some extent by setting inlets at the front and rear ends of the shielding cover, this design limits the operating space for maintenance personnel. Because the shielding cover only has inlets at the front and rear ends, maintenance personnel may encounter insufficient space when entering or leaving the work area, which undoubtedly increases the complexity and time cost of operation. Especially in emergency maintenance or scenarios requiring rapid response, this design may become a bottleneck hindering efficient operation.

[0004] During actual maintenance, maintenance personnel need to conduct a comprehensive inspection of the insulators, including their surface condition, cracks, and degree of contamination. However, due to the obstruction of the shielding cover, maintenance personnel cannot directly observe certain parts of the insulator, which may lead to potential safety hazards being overlooked. In order to conduct a thorough inspection, maintenance personnel may need to frequently disassemble and reinstall the shielding cover, which not only increases the workload but may also cause unnecessary damage to the insulators. Utility Model Content

[0005] The main objective of this invention is to provide a near-ground side-suspended insulator shielding cover for power distribution lines, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A near-ground side-suspended insulator shielding cover for a power distribution line includes a first shielding cover, a second shielding cover, a rear inlet and a front inlet. The first shielding cover and the second shielding cover together form a wedge-shaped shielding cover. The rear inlet is located at the rear end of the first shielding cover and the second shielding cover, and the front inlet is located at the front end of the first shielding cover and the second shielding cover. The first and second shields have inspection ports on their side walls. Each inspection port is connected to a flip-up inspection cover by a hinge device and a locking device. By opening the flip-up inspection cover, the near-ground suspension insulators of the power distribution lines inside the first and second shields can be inspected and maintained through the inspection port. The lower side wall of the flip-over inspection cover has a frame groove, and a transparent observation window is installed in the frame groove. A handle is installed at the outer end of the transparent observation window. The near-ground suspension insulators of the power distribution lines inside the first shield and the second shield can be observed through the transparent observation window.

[0007] As a preferred embodiment of this application, the cross-section of the flip-up inspection cover is designed in an "L" shape, and the edge of the flip-up inspection cover is connected to an insulating sealing strip by an adhesive, and achieves insulation sealing with the first shield and the second shield. As a preferred embodiment of this application, the locking devices are symmetrically distributed at the upper opening of the flip-top maintenance cover, and anti-slip pads are provided at the connection between the locking devices and the flip-top maintenance cover. The locking devices and the flip-top maintenance cover are fixed by bolts. As a preferred embodiment of this application, a portion of the hinge device is fixed to the flip-over inspection cover by bolts, and another portion of the hinge device is fixed to the first shield or the second shield by bolts. The hinge devices are symmetrically distributed on the flip-over inspection cover. As a preferred embodiment of this application, the edge of the transparent observation window is provided with a notch, the notch of the transparent observation window is adapted to the frame groove of the flip-up maintenance cover, the connection between the transparent observation window and the flip-up maintenance cover is connected with an insulating sealing strip by adhesive, and the transparent observation window and the flip-up maintenance cover are fixed by bolts. As a preferred embodiment of this application, the opening of the inspection port is provided with a blocking strip, which prevents the flip-over inspection cover from moving inward, and an insulating sealing strip is provided at the joint between the blocking strip and the flip-over inspection cover.

[0008] Compared with the prior art, the present invention has the following beneficial effects: Together, they create a safe and easy-to-operate maintenance environment. The wedge-shaped structure of the shielding not only protects the near-ground suspension insulators of the power distribution lines but also makes maintenance operations more convenient through its rational spatial layout. The flip-up maintenance cover design allows workers to easily open and close the maintenance port to perform necessary maintenance work.

[0009] The introduction of a transparent observation window has improved maintenance efficiency. Workers can directly observe the condition of the suspension insulators through the transparent window without opening the flip-up inspection cover, allowing for timely detection and handling of problems. This not only saves time but also reduces operational difficulty and risk.

[0010] These components also collectively ensure the equipment's insulation and sealing performance. A carefully designed insulating sealing strip and locking mechanism ensure a tight connection between the inspection cover and the shielding cover, effectively preventing external environmental influences on the equipment's interior. This not only improves equipment safety but also extends its service life. Attached Figure Description

[0021] The opening of the inspection port 10 is equipped with a blocking strip, which can effectively prevent the flip-over inspection cover 5 from moving inward and prevent the inspection cover from closing accidentally. The joint between the blocking strip and the flip-over inspection cover 5 is also equipped with an insulating sealing strip to ensure the overall sealing performance, thereby ensuring the insulation performance of the equipment.

[0022] The first shield 1 and the second shield 2 are connected by a hinge device 7, ensuring that the rear inlet 3 is located at the rear end and the front inlet 4 is located at the front end, forming a wedge-shaped structure. Inspection ports 10 are installed on the side walls of the first shield 1 and the second shield 2, respectively.

A frame groove is installed on the lower part of the side wall of the flip-up inspection cover 5. The transparent observation window 8 is installed into the frame groove and fixed with adhesive and bolts to ensure sealing performance. Locking devices 6 are symmetrically distributed at the upper opening of the flip-up inspection cover 5. Anti-slip pads are installed at the connection between the locking devices 6 and the flip-up inspection cover 5 and fixed with bolts.

[0023] Use the locking device 6 to open the flip-top inspection cover 5, ensuring its stability and safety. Observe the suspension insulators inside the first shielding cover 1 and the second shielding cover 2 through the transparent observation window 8 to check their condition. Enter the shielding cover through the maintenance port 10 to perform necessary maintenance operations.
