[0030] The implementation details of the technical solutions in the embodiments of the present utility model are elaborated in detail below:
[0031] First of all, it should be noted that the retractable lightning arrester protective cover provided by the present utility model is used to cover the porcelain bottle unit of the lightning arrester. The lightning arrester has three phases, that is, it is necessary to cover all three porcelain bottle units for insulation protection. Then, this retractable lightning arrester protective cover is used to cover the porcelain bottle of one phase, and the retractable lightning arrester protective cover proposed by the present utility model has a retractable function, and can adjust the covering space required for porcelain bottle units of different specifications and sizes.
[0032] According to one aspect of the present utility model, there is provided a retractable lightning arrester protective cover, including a first cover body 1 and a second cover body 2. The first cover body 1 is arranged on the side surface of the second cover body 2, and the first cover body 1 is communicated with the second cover body 2; the first cover body 1 includes a first base 11, a first movable cover body 12 and a first slide rail device 14. The first base 11 and the first movable cover body 12 are connected by the first slide rail device 14, and the first movable cover body 12 can be sleeved in the first base 11; the second cover body 2 includes a second base 21, a second movable cover body 22 and a second slide rail device 23. The second base 21 and the second movable cover body 22 are connected by the second slide rail device 23, and the second base 21 can be sleeved in the second movable cover body 22.
[0033] Specifically, as Figures 1 - 4 shown, where Figure 1 is a schematic diagram when the first cover body 1 and the second cover body 2 are extended in space, that is, a schematic diagram of the entire retractable lightning arrester protective cover extended in space, Figure 4 is a schematic diagram when the first cover body 1 and the second cover body 2 are contracted in space, that is, a schematic diagram of the entire retractable lightning arrester protective cover contracted in space.
[0034] Furthermore, the first base 11 and the first movable cover body 12 are connected by the first slide rail device 14. When the size of the porcelain bottle unit is small, the first movable cover body 12 can be sleeved in the first base 11 to save space. When the size of the porcelain bottle unit is large, the first movable cover body 12 can slide in combination with the first slide rail device 14 to increase the space covered by the first cover body 1 so that the porcelain bottle unit can be completely covered by the first cover body 1 for effective protection. Similarly, the space volume covered by the second cover body 2 can also be adjusted through the second base 21, the second movable cover body 22 and the second slide rail device 23, so as to adapt to porcelain bottle units of different specifications and sizes.
[0035] In an embodiment of the present utility model, the first movable cover 12 includes a plurality of limiting grooves 121. The plurality of limiting grooves 121 are provided on the side surface of the first movable cover 12 and are spaced apart in the vertical direction. A clamping member 111 is provided on the inner surface of the first base 11. The clamping member 111 can be embedded in the limiting groove 121 to fix the first movable cover 12. The material of the clamping member 111 is rubber.
[0036] Specifically, as Figure 2 shown, the first movable cover 12 slides on the first base 11 through a first guide rail device. The first movable cover 12 is fixed by the engagement of the limiting groove 121 and the clamping member 111. Since the material of the clamping member 111 is rubber, under the action of an external force, when the first movable cover 12 rises or falls in the vertical direction, it will drive the limiting groove 121 on the first movable cover 12 to move, thereby squeezing the rubber clamping member 111 and deforming the clamping member 111. When the clamping member 111 enters the adjacent limiting groove 121, it will be embedded in the current limiting groove 121. If the height needs to be further adjusted, the first movable cover 12 can be continuously moved by an external force to make the clamping member 111 enter the next limiting groove 121.
[0037] In an embodiment of the present utility model, the first slide rail device 14 includes a first guide rail groove 141 and a first guide rail block 142. The first guide rail block 142 is provided on the first base 11, and the first guide rail groove 141 is provided on the first movable cover 12. When the clamping member 111 is embedded in the topmost limiting groove 121, the first guide rail block 142 is located at the bottommost of the first guide rail groove 141. When the clamping member 111 is embedded in the bottommost limiting groove 121, the first guide rail block 142 is located at the topmost of the first guide rail groove 141.
[0038] Specifically, continuing as Figure 2 shown, there is a groove at the bottom of the first guide rail groove 141 that exactly fits the first guide rail block 142. When the first guide rail block 142 is fitted in the groove, the covering space of the first cover 1 is the largest at this time. By continuously reducing the height of the first movable cover 12, the first guide rail block 142 remains stationary at this time, while the first guide rail groove 141 continuously descends. When it descends to the lowest height, the covering space of the first cover 1 is the smallest.
[0039] Further, the clamping member 111 can be engaged with any one of the limiting grooves 121. When the clamping member 111 is engaged in the topmost limiting groove 121, the first guide rail block 142 is located at the bottommost of the first guide rail groove 141. At this time, the covering space of the first cover 1 is the largest. When the clamping member 111 is engaged in the bottommost limiting groove 121, the first guide rail block 142 is located at the topmost of the first guide rail groove 141. At this time, the covering space of the first cover 1 is the smallest.
[0040] In an embodiment of the present invention, the second sliding rail device 23 includes a second guide rail groove 231 and a second guide rail block 232. The second guide rail block 232 is disposed on the second movable cover 22, and the second guide rail groove 231 is disposed on the side surface of the second base 21.
[0041] Specifically, the second guide rail block 232 can move along with the movement of the second movable cover 22. There is a groove at the left end of the second guide rail groove 231 that exactly wedges with the second guide rail block 232. When the second guide rail block 232 is engaged in the groove, the covering space that the second cover 2 can cover is the largest at this time. When the second movable cover 22 moves under the action of an external force, the second guide rail block 232 moves accordingly, thereby adjusting the covering space of the second cover 2.
[0042] In an embodiment of the present invention, the first cover 1 includes a plurality of bending pieces 15, and the plurality of bending pieces 15 are all rotatably connected to the first base 11.
[0043] Specifically, the bending piece 15 can be rotatably adjusted to the angle of bending outwards. When encountering some porcelain bottles with relatively large sizes, the bending piece 15 can be made perpendicular to the ground at 90°, so as to maximize the covering space, that is, the covering space of the first cover 1 can be further adjusted by the bending piece 15.
[0044] In an embodiment of the present invention, the first movable cover 12 further includes two top covers 13. The two top covers 13 are both disposed on the upper surface of the first movable cover 12, and the two top covers 13 are detachably connected to the first movable cover 12.
[0045] Specifically, the top cover 13 can be opened. When wiring the porcelain bottle unit is required, the top cover 13 can be opened at this time to lead out the wire of the porcelain bottle from the opening formed by the top cover 13. At the same time, the top cover 13 is made of silica gel, and the color of the top cover 13 can be marked, so that the staff can identify which phase the current porcelain bottle unit belongs to through the color of the top cover 13, so as to improve the efficiency of subsequent maintenance and repair work.
[0046] In summary, in the present utility model, the first base 11 and the first movable cover 12 are connected by the first slide rail device 14. When the size of the insulator unit is small, the first movable cover 12 can be sleeved inside the first base 11 to save space. When the size of the insulator unit is large, the first movable cover 12 can slide in combination with the first slide rail device 14 to increase the space covered by the first cover 1 so that the insulator unit can be completely covered by the first cover 1 for effective protection. Similarly, the space volume covered by the second cover 2 can also be adjusted through the second base 21, the second movable cover 22 and the second slide rail device 23, so as to adapt to insulator units of different specifications and sizes.
[0047] Therefore, through the retractable lightning arrester protective cover provided by the present utility model, the first cover 1 and the second cover 2 can be retractable, so that the insulator units of different specifications and sizes can be effectively covered and protected, without independently designing protective covers of appropriate sizes for insulator units of different specifications and sizes, thereby reducing the protection cost of the lightning arrester.

It is easy to understand that the processes shown in the above-mentioned drawings do not indicate or limit the chronological order of these processes. Additionally, it is also easy to understand that these processes can be executed synchronously or asynchronously in, for example, multiple modules.
[0049] It should be understood that the present utility model is not limited to the exact structure described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present utility model is only limited by the appended claims.
