Description

Technical Field

[0001] This utility model belongs to the field of protective fences and relates to a substation protective fence. Background Technology

[0002] Currently, installing safety fences is one of the important technical measures to ensure the safety of on-site personnel. Safety fences not only prevent workers from accidentally entering live areas and ensure personal safety, but also effectively isolate live equipment, ensuring the normal operation of electrical equipment and the power grid. Existing protective fences, for the sake of lightweight design, generally use a combination of posts and isolation netting. The posts are connected by multiple screws, requiring repeated tightening and loosening of screws during assembly, a cumbersome process, high labor intensity, and low installation efficiency.

[0003] Therefore, this utility model provides a substation protective fence to solve the above problems. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a substation protective fence. The technical solution adopted is as follows: It includes a post, the post including a base with holes at four corners, a square tube fixedly connected to the upper surface of the base, through holes respectively opened at the upper and lower ends of adjacent side walls of the square tube, and symmetrical limiting notches opened on the left and right edges of the through holes. Fixing plates with central openings are fixedly installed in the middle and upper openings of the inner side walls of the square tube. A snap-fit ​​assembly is movably inserted into the central opening of the upper and lower fixing plates. The snap-fit ​​assembly includes a component that is movably inserted into the central opening of the upper and lower fixing plates. The connecting column has L-shaped fixing blocks fixedly mounted on the upper part of the corresponding through holes. Connecting inserts are fixedly mounted on the middle part of the lower sidewall edges of both ends of the L-shaped fixing blocks. A spring is mounted on the connecting column on the upper part of the upper L-shaped fixing block. A limiting ring is fixedly mounted on the connecting column on the upper part of the upper fixing plate. Movable rings with fixing columns on both sides are movably mounted on the column body above the limiting ring. A stop cap is fixedly installed on the top of the connecting column. The fixing columns on both sides of the movable ring have first insertion holes on both sides of the fixing plate. Isolation net components are inserted between adjacent columns through the corresponding through holes.

[0005] As a preferred embodiment of this utility model, a top cover is inserted into the upper end of the square tube.

[0006] As a preferred embodiment of this utility model, the opening on one side of the top cover is fixed to the square tube by screws.

[0007] As a preferred embodiment of this utility model, the isolation net assembly includes an insert tube that matches the through hole. Protrusions are respectively provided on both sides of the insert tube corresponding to the limiting notch. Second insertion holes are opened on the upper and lower sides of the insert tube corresponding to the insertion post. A vertical plate is fixedly connected to the outer ends of the upper and lower insert tubes on the same side. An isolation net is fixedly welded between the left and right vertical plates. By providing insert tubes with protrusions on both sides, quick connection can be achieved. The two ends of the isolation net are respectively inserted into the corresponding through holes of the post. The post at the lower part of the L-shaped fixing block of the locking assembly can be used to quickly assemble and fix the post and the isolation net.

[0008] As a preferred embodiment of this utility model, a connecting column is fixedly welded to the front edge of the isolation net on the right side. The upper, middle, and lower parts of the connecting column are respectively movably inserted into L-shaped fixing ears. The other end of the L-shaped fixing ears is fixedly connected to the front vertical plate. By using the connecting column and L-shaped fixing ears, it is easy to achieve a hinged connection between the isolation net on the right side and the front column. Thus, when the substation equipment is being maintained, the isolation net on the right side can be opened, improving the convenience of use.

[0009] As a preferred embodiment of this utility model, a reinforcing plate is fixedly welded to the right edge of the rear end of the isolation net on the right side. Three sets of fixing ears are fixedly welded to the upper, middle and lower parts of the reinforcing plate and the upper, middle and lower parts of the corresponding rear vertical plate, and each set of fixing ears is connected by a padlock.

[0010] The beneficial effects of this utility model are as follows: By setting a snap-fit ​​component inside the column, lifting the connecting column of the snap-fit ​​component compresses the spring, thereby pulling the inserts at both ends of the L-shaped fixing block out of the corresponding insertion tubes of the isolation net component, thus improving the ease of disassembly. When building the fence, the connecting column of the snap-fit ​​component is lifted, inserted into the corresponding insertion tube of the isolation net component, and the connecting column is released. Under the action of the spring, the connecting column and the L-shaped fixing block are pressed down, thereby inserting the insert at the lower end of the L-shaped fixing block into the second insertion hole of the insertion tube, thus quickly completing the assembly between the isolation net component and the column, reducing labor intensity and improving installation efficiency.
