Description

Technical Field

[0001] The utility model belongs to the technical field of safety facilities for access roads of wind power projects in mountainous areas, and in particular relates to a detachable guardrail for access roads of wind power plants. Background Art

[0002] With the development of wind power projects in mountainous areas, due to the regional nature of wind resources, wind farm construction is always carried out in phases. Taking into account the site limitations in mountainous areas, each phase of wind farm construction uses the existing access roads, removes the safety fences of the existing access roads, and restores the safety fences after the construction is completed.

[0003] Traditional guardrail designs often focus on their structural strength and stability, but ignore the convenience of disassembly and reinstallation. Safety guardrails need to be dismantled during each wind farm construction, which not only damages the roads, but also leads to a waste of safety guardrail resources. In addition, traditional guardrails often lack an effective buffer mechanism during the disassembly process. Due to the heavy weight of components such as corrugated plates, workers are easily injured during disassembly, thereby increasing the risk of injury to workers, which not only affects the construction progress, but also poses a serious threat to the lives of workers. Utility Model Content

[0004] The purpose of the utility model is to provide a detachable guardrail for a wind farm access road, so as to solve the problems mentioned in the background technology.

[0007] Furthermore, the sleeve includes a cylinder, a compression chamber, a piston rod, an infusion tube, a sealing cap and a fixing buckle, the cylinder is fixed to the ground on both sides of the access road to the wind farm, and a column is installed inside the cylinder for sliding up and down; a compression chamber is opened inside the cylinder, the interior of the compression chamber is filled with liquid, and a piston rod is installed inside the compression chamber for sliding, wherein the upper end of the piston rod is fixed to the lower side surface of the adapter frame by a bolt; an infusion tube is fixed to the outer side surface of the lower end of the cylinder through a flow control valve, wherein the interior of the infusion tube is communicated with the interior of the compression chamber, and a sealing cap is fixed to the other end of the infusion tube; a fixing buckle is fixed to the outer side surface of the cylinder by welding, and an infusion tube is buckled inside the fixing buckle, with such an arrangement, firstly, after the first locking bolt is removed, the column can slide inside the cylinder, and secondly, it can avoid injuries to workers when the adapter frame and the corrugated plate are disassembled.

[0008] Furthermore, the adapter frame includes a frame, a second locking bolt, a third locking bolt and a base plate, the frame is fitted on the outer side of the column, and the other side of the frame is fitted with a corrugated plate; the second locking bolt fixes the frame and the corrugated plate together, and the third locking bolt fixes the column and the frame together; a base plate is fixed to the middle part of the lower side of the frame by welding, and the lower side of the base plate is fixed to the upper end of the piston rod by bolts. Such a setting can fix the corrugated plate to the outer side of the column.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model effectively avoids the risk of workers being injured by the adapter frame and the corrugated plate by utilizing the liquid buffer mechanism in the compression chamber during the disassembly process, thereby significantly improving work safety. At the same time, because the guardrail needs to be restored after the construction of the wind farm is completed, the guardrail can be quickly disassembled and reinstalled through simple steps, which not only simplifies the entire maintenance process, but also significantly reduces the investment cost and shortens the construction period.
