Technical Field
[0001] The utility model belongs to the technical field of guardrails, and in particular relates to a retractable guardrail, an automatically retractable guardrail assembly and an overflow weir guardrail. Background Art
[0002] In engineering practice, the grade and level of the overflow weir are generally determined by the normal water storage level of the river and the design flood level, that is, the elevation of the overflow weir is related to the water level calculation and hydraulic layout, and once determined, it is inconvenient to change. Most of the existing overflow weirs use conventional railings as protection. When there is heavy rain or flood discharge, the upstream flood will be mixed with branches, water plants and other debris, and cannot pass through the gaps in the guardrails and accumulate. At the least, it will cause damage to the guardrail, and at the worst, it will cause damage to the main structure of the overflow weir. In the most serious case, it will cause floods to overflow the river channel, affecting the safety of life and property of the surrounding people. Although the document number CN216366760U "A kind of sewage interception device for overflow weir" also discloses the installation of guardrails next to the overflow weir, it is mainly for intercepting debris. Once a flood occurs, weeds or branches from upstream will accumulate at the guardrail, and eventually cause the guardrail to be overloaded. Utility Model Content

A blocking plate 1111 can be set on each of the bases.
[0038] like Figure 3 and Figure 4 As shown, the traction member 113 in the above technical solution includes a column 1131, a traction rope 1132 and two fixed pulleys, the column 1131 is erected on the ground and away from the middle part of the side where the guardrail body 112 lies down, the two fixed pulleys are installed at the upper end of the column 1131, and are respectively a first fixed pulley 1133a and a second fixed pulley 1133b, the axle of the first fixed pulley is arranged along the front-to-back direction, and the axle of the second fixed pulley is arranged along the vertical direction, one end of the traction rope 1132 is connected to the upper end of the middle part of the guardrail body 112 and constitutes the connecting end of the traction member 113, the other end of the traction rope 1132 passes around the axles of the first fixed pulley and the second fixed pulley in turn and faces forward or backward to constitute the traction end of the traction member 113, its structure is simple, and the direction of the traction rope can be bent by arranging the first fixed pulley and the second fixed pulley, so as to apply a force to the traction rope from the bank of the river channel.
[0039] The traction rope 1132 described in the above technical solution is a steel wire rope, which has high structural strength.
[0040] Example 2
[0041] like Figure 5 As shown, this embodiment provides an automatic retractable guardrail assembly, including a driving member 12 and multiple retractable guardrails 11 as described in Example 1, the multiple retractable guardrails 11 are linearly arranged in the front-to-back direction, the driving member 12 is placed in front of or behind the multiple retractable guardrails 11, and its driving end is connected to the traction ends of the multiple traction members 113, and its structure is simple, so that multiple retractable guardrails can be linearly arranged to meet the length requirements of the overflow weir, and the multiple retractable guardrails share a driving member to drive them to lie down or stand up synchronously.

The two automatic retractable guardrail assemblies can share a linear drive member. In this case, one end of the overflow weir can be provided with a threading hole running through both sides thereof (see Figure 7 The third fixed pulley 6 is arranged at both ends of the threading hole. At this time, the main rope on one side of the overflow weir can be passed through the threading hole to the opposite side of the overflow weir. At this time, the two main ropes can be connected to the driving end of the linear driving member. At this time, the linear driving member drives the two main ropes to synchronously drive all the retractable guardrails to lie down or stand upright.
[0050] The linear drive is electrically connected to the controller, which may be an ARM series single chip microcomputer. Note that the control box is arranged on the bank of the river channel and close to the end of the overflow weir, but it must be ensured that it will not be submerged during floods.
[0051] Among them, the water level monitor can adopt the structure disclosed in the document number CN217818939U "A River Water Level Monitor" (of course, its solar power generation panel can be cancelled and directly powered by the mains).
