[0002] In order to ensure the stable and reliable operation of the equipment in the hydropower station, it is necessary for equipment maintenance personnel to regularly inspect, maintain and repair the equipment. Since some of the equipment structures in the hydropower plant are relatively complex, the overhaul process takes a long time. In order to ensure the safety of this area during the overhaul period, a fence is generally set up for warning and protection. However, the existing fences generally need to be fixed to the ground by bolts, which is not only troublesome to operate and inconvenient to install, but also easily damages the ground after multiple installations. Therefore, the existing technology has the problems of inconvenient installation and easy damage to the ground. Summary of the Invention

Detailed implementation mode

[0019] The present invention will be further described below in conjunction with the attached drawings and embodiments, but it shall not be used as a basis for limiting the present invention.

[0020] Embodiment. A pre-embedded quick plug-in fence for a hydropower station is composed as Figures 1-6 shown, including an embedded box body 1 embedded in the ground. A vertical return spring 2 is arranged in the middle of the embedded box body 1. Wedge-shaped self-locking devices 3 are arranged on both sides of the vertical return spring 2. A cover body 4 is arranged above the embedded box body 1; it also includes a plug-in column 5 that cooperates with the wedge-shaped self-locking device 3, and a fence 6 is arranged between adjacent plug-in columns 5.

[0021] A vertical cavity 101 is arranged in the middle of the embedded box body 1, and horizontal cavities 102 are arranged on both sides of the vertical cavity 101; the vertical return spring 2 is located in the vertical cavity 101, and the wedge-shaped self-locking device 3 is located in the horizontal cavity 102.

[0022] The wedge-shaped self-locking device 3 includes a telescopic rod 301 arranged in the horizontal cavity 102. A spring 302 is sleeved on the telescopic rod 301, and a wedge-shaped self-locking block 303 is arranged at the outer end of the telescopic rod 301.

[0023] The plug-in column 5 includes a column body 501. An annular embedding groove 502 is arranged at the bottom of the column body 501, and two unlocking convex blocks 503 that are distributed at 180° and cooperate with the wedge-shaped self-locking block 303 are arranged in the annular embedding groove 502.

[0024] A self-return mechanism 7 is also arranged between the plug-in column 5 and the fence 6.

[0025] The self-return mechanism 7 includes a bearing frame 701 arranged on the side of the plug-in column 5. An inclined top piece 702 is arranged in the bearing frame 701, and a pulling-back component 703 is arranged on the side of the top piece 702; it also includes a plug-in frame 601 located on the side of the fence 6, and a serrated structure 602 that cooperates with the top piece 702 is arranged on one side of the bottom of the plug-in frame 601.

[0026] The self-return mechanism 7 includes a receiving frame 701 provided on the side of the insertion post 5. A ratchet wheel 704 is provided inside the receiving frame 701, and a bird-blocking structure 705 is provided above the ratchet wheel 704. It also includes an insertion frame 601 located on the side of the fence 6. A sawtooth structure 602 that cooperates with the ratchet wheel 704 is provided on one side of the bottom of the insertion frame 601.

[0027] The cover body includes a hollow outer cover. An inner cover is provided inside the outer cover above the vertical return spring, and a limiting block is provided at the top of the inner wall surface of the outer cover. Usually, the inner cover is in the top position under the spring force of the vertical return spring, which can prevent garbage from entering. When in use, after the insertion post is inserted, the inner cover will move downward along with the insertion. After the insertion post is pulled out, it will reset automatically under the spring force. Both ends of the inner cover are inclined guiding surfaces for contacting and guiding the wedge-shaped self-locking block.

[0028] The wedge-shaped self-locking device: When the insertion post is inserted in the correct direction, the wedge-shaped self-locking block will extend into the annular embedding groove under the spring force to lock the insertion post. When the insertion post needs to be pulled out, just rotate the insertion post, and the unlocking convex block in the annular embedding groove of the insertion post will contact the wedge-shaped self-locking block and squeeze the wedge-shaped self-locking block to retract, pushing it back to its original position, so that the wedge-shaped self-locking block disengages from the annular embedding groove, allowing the insertion post to be pulled out smoothly.

[0029] The connection between the fence and the insertion post is realized through the self-return mechanism.

[0030] Insert the insertion frame of the fence into the receiving frame. The sawtooth structure on the side of the insertion frame contacts the top piece, and the top piece is pushed into the sawtooth structure to prevent it from being pulled out. When it needs to be pulled out, the adjacent return component needs to be pulled to retract the top piece.

[0031] With the ratchet wheel and the bird-blocking structure, when the insertion frame of the fence is inserted, the sawtooth structure drives the ratchet wheel to rotate. At this time, when the ratchet wheel rotates counterclockwise, the bird-blocking structure will not block the ratchet wheel. When pulling out, the ratchet wheel rotates clockwise, and the bird-blocking structure blocks the ratchet wheel at this time. Only after removing the bird-blocking structure can the ratchet wheel rotate clockwise, which is convenient for pulling out the fence.
