[0026] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0027] like Figure 1-5The figure shows a specific embodiment of a visualized electric grounding ring insulating shielding cover, which is a visualized electric grounding ring insulating shielding cover, comprising a front end plate 1 and a rear end plate 2 connected to the front end plate 1 with a gap, wherein the left side of the front end plate 1 is extended to form an extension plate, the lower edge of the extension plate is connected to a side baffle 3, and the inner surface of the front end plate 1 is connected to a hook portion 4 with an opening facing upward. As a preferred parameter: the distance between the front end plate 1 and the rear end plate 2 is 80 mm, and the width of the hook portion 4 does not exceed 60 mm. The hook portion 4 includes a connecting plate 5, which is fixed to the inner surface of the front end plate 1 by rivets, and the lower edge of the connecting plate 5 is bent and extended upward to form an inclined plate 6, and the inclined plate 6 constituting the hook is used to hook the charged metal ring 8 on the grounding ring.

[0028] Usage: Use a link rod or other insulating installation tools to connect with the insulating shield. The connection method can be screws or clamps. First, clamp the wire between the side baffle 3 and the front end plate 1, and follow the Figure 1 Pull down the insulating shielding cover in the direction of the arrow shown. The first stage: the inclined plate 6 contacts the upper edge of the metal ring 8 on the grounding ring. The second stage: continue to pull down the insulating shielding cover, at this time the inclined plate 6 is slightly deformed, that is, the inclined plate 6 expands and opens. The third stage: after the inclined plate 6 passes the upper edge of the metal ring 8, the inclined plate 6 returns to its original state, and the inclined plate 6 is just stuck in the metal ring 8. Finally, the side baffle 3 fits and sticks on the left side of the metal ring 8 to limit the left and right movement of the insulating shielding cover. At the same time, the inclined plate 6 is stuck in the metal ring 8 to limit the up and down movement of the insulating shielding cover. Through the above method, the insulating shielding cover can be installed in place without power outage and locked firmly. When daily maintenance work is required, the grounding wire can be hung in the traditional way, which does not affect normal use, and can effectively prevent the charged metal ring 8 from contacting with external branches and the like to cause a short circuit in the line. It achieves technical characteristics such as not affecting daily maintenance work (hanging the grounding wire) and protecting the normal operation of the circuit. Moreover, in the technical solution of the present application, due to the gap setting between the front end plate and the rear end plate 2, and the non-opening setting on the left side of the front end plate, openings are left on multiple sides, which does not affect daily operation and maintenance temperature measurement and observation.

[0029] In a preferred embodiment, the lower edge of the inclined plate 6 is in contact with the inner surface of the rear end plate 2, and the connection is firm and practical.

[0030] In a preferred embodiment, an upper end plate 7 is connected between the upper end of the front end plate 1 and the upper end of the rear end plate 2, which has a simple structure and strong practicality.

[0031] In a preferred embodiment, the front end plate 1, the rear end plate 2 and the upper end plate 7 are integrally formed, which is easy to process and has good stability.

[0032] In a preferred embodiment, the front end plate 1, the extension plate and the side baffle plates 3 are integrally formed, which is easy to process and has good stability.

[0033] In a preferred embodiment, the connecting plate 5 and the inclined plate 6 are integrally formed, which is easy to process and has good stability.

[0034] In a preferred embodiment, the length of the side baffle plate 3 is less than that of the extension plate. The length of the side baffle plate 3 does not need to be too long, as long as it can limit the movement of the insulating shielding cover to the left and right, thereby reducing material costs.

[0035] In a preferred embodiment, the front end plate 1, the rear end plate 2, the upper end plate 7, the extension plate, and the side baffle plate 3 are transparent plates. The present application adopts a transparent visual design, which can realize the visibility of the internal wiring ring, which is convenient for the efficient installation of the insulating shielding cover and is also conducive to the subsequent hanging of the grounding wire.

[0036] In a preferred embodiment, the front end plate 1, the rear end plate 2, the upper end plate 7, the extension plate, and the side baffle plate 3 are acrylic plates. The material of the acrylic plate can make the insulating shielding cover have a certain elasticity. When necessary, the insulating shielding cover can be stretched open and the grounding wire can be inserted into the metal ring 8 to hang the grounding wire. The insulating shielding cover can also be restored to its original state after the detection is completed.

[0037] The present application does not limit the specific dimensions of the front end plate 1, the rear end plate 2, the upper end plate 7, the extension plate, and the side baffle plate 3. As long as the grounding ring can be completely covered, technical personnel in this field can make adjustments based on actual needs. For the size of the inclined plate 6, it is preferably matched with the size of the metal ring 8 to achieve a secure fit.

[0038] Finally, it should be noted that the present invention is not limited to the above embodiments, and there are many variations. All variations that can be directly derived or associated with the content disclosed by ordinary technicians in this field should be considered as the protection scope of the present invention.
