Temporary safety fence with embedded parts for power construction

Abstract

The application discloses an easy-to-assemble-and-disassemble temporary safety fence with embedded parts for power construction, which comprises a net collector rod, a fence net, a fence rod, a hook, an embedded support part and a limiting tube assembly. The limiting tube assembly is arranged in the embedded support part. The straight tube of the limiting tube assembly is internally provided with a movable plugging block assembly. The movable plugging block assembly is used for plugging the top of the straight tube. A guide groove is formed in the straight tube to limit the moving track of the guide block. When the fence rod is inserted into the straight tube, the movable plugging block assembly is pressed down. The upward movement of the guide block is limited by the guide groove. When the fence rod is pulled out, the movable plugging block assembly is pressed down again. The movable plugging block assembly is pushed upward by the spring to reset, so that the insertion and pulling-out operation of the fence rod is simpler. The limiting tube assembly is connected with the embedded support part in a threaded connection mode, so that the limiting tube assembly is convenient to disassemble and assemble, and thus the cleaning and maintenance of the limiting tube assembly are facilitated.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of fences, in particular to a temporary safety fence with embedded parts for power construction. BACKGROUND

[0002] In order to ensure the stable and reliable operation of the equipment in the power station, the equipment maintenance personnel need to regularly inspect, maintain and repair the equipment. In order to ensure the safety of the area during the maintenance period, a fence is generally set up for warning and protection.

[0003] The existing temporary fence generally fixes a fixed part on the bottom surface to facilitate the fixation of the temporary fence. For example, a Chinese patent with publication number CN115522811A discloses a pre-embedded quick plug-in fence for a hydropower station. A pre-embedded box body is arranged in the ground, and a vertical reset spring and a wedge-shaped self-locking device are arranged in the pre-embedded box body. The vertical reset spring and the wedge-shaped self-locking device cooperate with the annular embedded groove and the unlocking protrusion arranged at the bottom of the plug-in column to realize the insertion and extraction of the plug-in column. Meanwhile, a self-rebound mechanism is arranged between the plug-in column and the fence to facilitate the installation and disassembly of the plug-in column and the fence. The whole structure of the present application is simple and convenient to install, does not need to be fixed with bolts, simplifies the installation process, and can be used repeatedly without damaging the ground.

[0004] Although the above-mentioned pre-embedded quick plug-in fence for a hydropower station has certain advantages in the installation and fixation of the plug-in column and the installation and disassembly of the plug-in column and the fence, it still has certain disadvantages.

[0005] 1. The plug-in column needs to be inserted at a certain angle, and the plug-in column needs to be rotated when being extracted, so the disassembly operation is not convenient.

[0006] 2. The pre-embedded box body is covered by an inner cover, which can effectively prevent sundries from entering the pre-embedded box body. However, the inner cover is a movable structure, which can easily cause dust and water to enter the pre-embedded box body, causing the spring inside the pre-embedded box body to rust. In addition, dust can affect the movement of the inner cover and the wedge-shaped self-locking block. When the inside of the pre-embedded box body needs to be cleaned or maintained, the whole pre-embedded box body needs to be taken out, which makes cleaning and maintenance inconvenient. SUMMARY
