Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a guardrail for water utilization construction. Background Art

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. Projects built to eliminate water disasters and develop and utilize water resources are divided into flood control projects, agricultural water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and tidal flat reclamation projects according to their service objects. Water conservancy projects that can serve multiple goals such as flood control, water supply, irrigation, and power generation at the same time are called comprehensive water conservancy projects. At present, during the construction of water conservancy projects, it is necessary to set up protective fences on the outside of the construction site to prevent pedestrians from accidentally entering the construction area and causing safety accidents.

[0024] As a technical optimization solution of the present invention, by setting a connecting mechanism 6, the circular groove 61 can movably limit the first plug column 62 and the second plug column 63, and the movably limiting position of the first plug column 62 and the second plug column 63 can movably limit the first positioning rod 4 and the second positioning rod 5, thereby improving the stability of the first positioning rod 4 and the second positioning rod 5.

[0025] refer to Figure 3 The limiting component 7 includes a first through groove 71, and a second through groove 72 is opened at the bottom of the inner side of the surface of the railing 1. The first through groove 71 is connected to the second through groove 72. The surface of the first positioning rod 4 is movably connected to the inner wall of the first through groove 71, and the surface of the second positioning rod 5 is movably connected to the inner wall of the second through groove 72.

[0026] As a technical optimization solution of the present invention, by setting a limit component 7, the opening width of the first through groove 71 is larger than the second through groove 72, and the diameter of the first positioning rod 4 is larger than the second positioning rod 5. The first through groove 71 can limit the first positioning rod 4, and the second through groove 72 can limit the second positioning rod 5.

[0027] refer to Figure 2 The left and right sides of the guardrail net 2 are fixedly connected with connecting rods 8, and the bottom of the first column 62 and the top of the second column 63 are provided with slots 9, and the surfaces at both ends of the connecting rod 8 are movably connected to the inner walls of the slots 9.

[0028] As a technical optimization solution of the present invention, by setting the connecting rod 8 and the slot 9, the slot 9 can limit the connecting rod 8, and the connecting rod 8 can limit the guardrail net 2, thereby achieving the effect of convenient installation.

[0029] refer to Figure 2A connecting plate 10 is provided on the front side of the surface of the railing 1, and two first bolts 11 are provided on the inner side of the front side of the connecting plate 10. The ends of the two first bolts 11 close to the railing 1 successively penetrate the connecting plate 10 and the railing 1 and extend to the inside of the railing 1. The first bolts 11 are threadedly connected to the connecting plate 10 and the railing 1. Two second bolts 12 are provided on the outer side of the front side of the connecting plate 10. The ends of the two second bolts 12 close to the railing 1 penetrate the connecting plate 10 and extend to the rear side of the connecting plate 10. The second bolts 12 are threadedly connected to the connecting plate 10.

[0030] As a technical optimization solution of the present invention, by setting a connecting plate 10, a first bolt 11 and a second bolt 12, the first bolt 11 is used to connect the railing 1 and the connecting plate 10, and the second bolt 12 facilitates the user to install and connect the railing 1 with other railings 1 that need to be spliced ​​into a row.

[0031] refer to Figure 2 The top of the inner wall surface of the circular groove 61 is movably connected to a rubber plug 13 , and the top of the rubber plug 13 is fixedly connected to a rotary plate 14 .

[0033] After the first and second positioning rods 5 are lowered, the two second plugs 63 are inserted into the grooves 61, and the second positioning rods 5 are lowered to the bottom of the second grooves 72. The distance between the two railings 1 is determined. Then, the connecting rod 8 is moved so that its bottom end is inserted into the slot 9 at the top of the second plug 63. Then, the first positioning rod 4 is moved so that the two first plugs 62 enter the interior of the groove 61, and the first positioning rod 4 falls to the lowest point of the first groove 71. At this time, the top of the connecting rod 8 is inserted into the slot 9 at the bottom of the first plug 62, thereby completing the installation and positioning of the guardrail net 2, and can prevent the guardrail net 2 from being damaged by excessive grooving. Finally, the rubber plug 13 is driven into the interior of the circular groove 61 by rotating the rotary plate 14, so that the first plug 62 can be positioned to prevent it from shaking up and down. The assembly is relatively convenient and convenient for the user to move and store the components separately.

[0034] To sum up: this kind of guardrail for water utilization construction can position the two railings 1 by setting the first positioning rod 4 and the second positioning rod 5, so as to avoid the guardrail net 2 from being pulled and damaged, and solves the problem that the guardrail net is made of soft material, so it is not easy for users to position the two guardrail rods. If the rods are placed too close, the guardrail net will be wrinkled and uneven, and the protection will be not high. If they are placed too far, it will easily cause the guardrail net to be subjected to a large pulling force, so it is easy to be damaged after long-term use, and the use effect is not good.
