Embodiment 1

[0036] like figure 2 As shown, a quick-opening high-voltage cable grounding box body includes a rectangular rear case 3 with an open front and a rectangular case cover 1 covering the front of the rear case 3, and a A sealing rubber ring, a hinge assembly is connected between the left side of the rear case 3 and the case cover 1, a locking assembly 6 is connected between the right side of the rear case 3 and the case cover 1, and the case cover 1 and the rear case 3 form a closed cavity. The back of the rear case 3 is provided with hanging lugs 4 near the four corners, two handles 2 are symmetrically arranged on the front of the case cover 1 , and four wire pipes 5 are provided at the bottom of the rear case 3 .

[0037] like figure 2 , Figure 4 and Image 6As shown, the hinge assembly includes two rotating rod seats 7 vertically arranged on the left side of the case cover 1, and the two rotating rod seats 7 are symmetrical up and down. The left end of the rotating rod ...

Embodiment 2

[0051] like figure 1 and Figure 5 Shown, the difference between this embodiment and embodiment 1 is:

[0052] The hinge assembly is a hinge, and the rear case 3 and the box cover 1 are respectively welded to the corresponding parts of the hinge.

[0053] The locking assembly 6 includes a first connecting plate 17 that is fixedly connected with the third lug that is welded on the right side of the case cover 1 by screws, a lock tongue 18 that is welded on the outside of the first connecting plate 17, and a bolt that is welded on the rear shell 3. The fourth lug on the right side is fixedly connected to the second connecting plate by screws and is rotatably connected to the locking hook 19 on the outside of the second connecting plate 20 . The right end of the rear part of the lock tongue 18 is an outwardly protruding lock post 22 , and the front end of the lock hook 19 is an arc-shaped hook for hooking the lock post 22 .

[0054] The arc-shaped hook is arranged eccentricall...

Embodiment 3

[0056] The difference between this embodiment and Embodiment 2 is that the hinge in Embodiment 2 is removed and replaced with the locking assembly 6 in Embodiment 2. Therefore, in this embodiment, after the locking assembly is unlocked, the box cover 1 can be removed from the rear case 3.

[0057] At present, the technical solution of this application has undergone a pilot test, that is, a small-scale experiment of the product before mass production; after the pilot test is completed, a user survey has been carried out in a small area, and the survey results show that the user satisfaction is high; Now it has started to prepare for the formal production of the product for industrialization (including intellectual property risk early warning research).

Abstract

The invention discloses a quick-opening high-voltage cable grounding box body comprising a rear shell with an opening in the front and a box cover covering the front of the rear shell, the rear shell and the box cover are matched in a sealing mode, and the two opposite side faces of the rear shell are connected with a hinge assembly and a locking assembly respectively. The hinge assembly and the locking assembly are connected with the corresponding sides of the box cover respectively, and the box cover and the rear shell form a closed cavity. The hinge assembly comprises a rotating rod seat, a middle block, a rotating rod, a handle and a fixed seat, the locking assembly comprises a movable block and a fixed block, after the box cover is covered, the handle is rotated to drive the box cover to transversely move along the front face of the rear shell, and the box cover is tightly pressed on the rear shell under the action of the movable block and the fixed block. When the box cover is opened, the handle only needs to be rotated reversely, the movable block is driven to move transversely, the handle is pulled, and then the box cover can be opened. Therefore, the box cover is more convenient to open and close, the efficiency is higher, and more labor is saved.

Description

technical field [0001] The invention relates to the technical field of high-voltage cable grounding equipment, in particular to a quick-opening high-voltage cable grounding box body. Background technique [0002] For 35kV large-section power cables and single-core cables with voltage levels of 66kV, 110kV and above, the high-voltage cable grounding box is a special device for protecting the metal sheath of the cable, which can avoid lightning strikes and induced overvoltages on the cable sheath. Effective protection of the inner cable sheath. With the development of cable laying, the cable sheath grounding system is gradually complex and large, so the proportion of installation, maintenance and maintenance of the high-voltage cable grounding box is increasing. The sealing box cover of the existing high-voltage cable grounding box is mainly realized by the bolts densely distributed around it. , It is very difficult to disassemble and assemble, which reduces the work efficien...
