Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 As shown, a protective device for water conservancy and hydropower engineering projects includes multiple groups of guardrails 1, ear plates 2 are provided at the upper and lower ends of one side of the guardrail 1, and corresponding ear plates 6 are provided at the upper and lower ends of the other side of the guardrail 1. A rotating plate 4 is installed between the ear plate 2 on one side of the guardrail 1 and the ear plate 6 on the other side of the adjacent guardrail 1, the ear plate 2 and the rotating plate 4 are rotatably connected by a rotating shaft 3, and the ear plate 6 and the rotating plate 4 are rotatably connected by a rotating shaft 5. Multiple groups of guardrails 1 are spliced ​​to form an open or closed polygon.

[0026] Specifically, eight groups of guardrails 1 are provided, and the eight groups of guardrails 1 are spliced ​​to form a quadrilateral guardrail, and an opening is provided between two adjacent groups of guardrails 1 on any side.

[0027] Universal wheels 7 are provided at the bottom of the plurality of guardrails 1, a poster fixing mechanism 8 is installed on the outer wall of any one or more guardrails 1, a poster body 81 is installed on the poster fixing mechanism 8, and a night warning mechanism 9 is installed on the upper end of any one or more guardrails 1.

[0028] Specifically, there are two groups of poster fixing mechanisms 8, which are respectively arranged on two adjacent groups of guardrails 1. There are four groups of night warning mechanisms 9, which are respectively arranged on the upper ends of the remaining four groups of guardrails 1.

[0029] A further solution to implement the present invention is as follows: Figure 2 As shown, each group of the poster fixing mechanisms 8 is provided with two, and the two poster fixing mechanisms 8 are respectively provided at the upper and lower ends of the guardrail 1. The poster fixing mechanism 8 includes a mounting seat 84 and a fixing assembly 85. The outer side of the mounting seat 84 is provided with a card slot 83, and the side of the card slot 83 is provided with a fixing assembly 85. The upper and lower ends of the poster body 81 are provided with card blocks 82, and the two side ends of the card blocks 82 are provided with fixing holes 86. The card blocks 82 at the upper and lower ends of the poster body 81 are inserted into the card slots 83 of the mounting seat 84 and fixed by the fixing assembly 85.

[0030] like Figure 3As shown, the fixing assembly 85 includes a spring 851 and a bayonet 853. A stepped hole is provided inside one side of the slot 83, and a spring 851 is installed in the large hole of the stepped hole. A limit plate 852 is provided at one end of the bayonet 853, and the other end of the bayonet 853 is an arc top structure. One end of the limit plate 852 is placed in the large hole of the stepped hole of the slot 83 and contacts one end of the spring 851. The bayonet 853 is placed in the small hole of the stepped hole and protrudes out of the small hole. Under the action of the spring 851, the bayonet 853 is snapped into the fixing hole 86 at the side end of the clamping block 82.

[0031] Through the above technical solution, when installing the poster body 81, it is only necessary to insert the block 82 at the upper and lower ends of the poster body 81 into the inside of the slot 83 inside the side of the mounting seat 84, and then cooperate with the fixing component 85 and the fixing hole 86 to achieve the installation and fixation of the poster body 81. When the block 82 is inserted into the slot 83, the block 82 will squeeze the bayonet 853 and drive the spring 851 to compress. When the bayonet 853 is aligned with the fixing hole 86, the spring 851 rebounds, thereby driving the bayonet 853 to insert into the inside of the fixing hole 86 to achieve the fixation of the poster body 81. The setting of the limit plate 852 can prevent the vertical part of the bayonet 853 from being inserted into the inside of the fixing hole 86, avoiding the inconvenience of disassembling the poster body 81 later.

[0032] A further solution to implement the present invention is as follows: Figure 4 As shown, the night warning mechanism 9 includes a mounting box 95, a battery 94 and a warning light 91. The mounting box 95 is arranged on the top of the guardrail 1. The warning light 91 is installed on the top of the mounting box 95. The mounting box 95 is internally provided with a battery 94, and the battery 94 is electrically connected to the warning light 91.

[0033] A driving motor 93 is installed inside the installation box 95 . The driving motor 93 is electrically connected to a battery 94 . A rotating shaft 92 is installed at the output end of the driving motor 93 . The warning light 91 is arranged at the upper end of the rotating shaft 92 .

[0034] Through the above technical solution, the drive motor 93 inside the installation box 95 is opened, and the drive motor 93 drives the rotating shaft 92 to rotate through the output end. The rotation of the rotating shaft 92 drives the warning light 9191 to rotate, thereby warning the passing people and vehicles at night. The battery 94 can power the drive motor 93 and the warning light 91.

[0035] Example 2

[0036] This embodiment is based on embodiment 1, and the difference is that one of the unfolding arrangements is that the guardrails 1 are provided in six groups, and the six groups of guardrails 1 are spliced ​​to form a triangular guardrail, and an opening is provided between two adjacent groups of guardrails 1 on any side.

[0037] In addition, two groups of poster fixing mechanisms 8 are provided, and the two groups of poster fixing mechanisms 8 are respectively provided on two adjacent groups of guardrails 1. Four groups of night warning mechanisms 9 are provided, and the four groups of night warning mechanisms 9 are respectively provided on the upper ends of the guardrails 1 of the remaining four groups.

[0038] Example 3

[0039] This embodiment is based on embodiment 1, and the difference is that one of the unfolding arrangements is that the guardrails 1 are provided in ten groups, and the ten groups of guardrails 1 are spliced ​​to form a pentagonal guardrail, and an opening is provided between two adjacent groups of guardrails 1 on any side.

[0040] In addition, two groups of poster fixing mechanisms 8 are provided, and the two groups of poster fixing mechanisms 8 are respectively provided on two adjacent groups of guardrails 1. Four groups of night warning mechanisms 9 are provided, and the four groups of night warning mechanisms 9 are respectively provided on the upper ends of the guardrails 1 of the remaining four groups.

[0041] How it works:

[0042] When the utility model is used, firstly, the number of groups of guardrails 1 to be used is determined according to the size and shape of the municipal maintenance site, and then they are assembled and spread out into an appropriate shape according to the shape of the maintenance site, and then installed and assembled on the guardrails 1 where the poster fixing mechanism 8 and the night warning mechanism 9 are required to be installed.

[0043] When installing the poster body 81, it is only necessary to insert the blocks 82 at the upper and lower ends of the poster body 81 into the slots 83 inside the side of the mounting seat 84. When the blocks 82 are inserted into the slots 83, the blocks 82 will squeeze the bayonet 853 and drive the spring 851 to compress. When the bayonet 853 is aligned with the fixing hole 86, the spring 851 rebounds, thereby driving the bayonet 853 to insert into the fixing hole 86 to fix the poster body 81. The setting of the limit plate 852 can prevent the vertical part of the bayonet 853 from being inserted into the fixing hole 86, thereby avoiding inconvenience in disassembling the poster body 81 later. Open the drive motor 93 inside the installation box 95, and the drive motor 93 drives the rotating shaft 92 to rotate through the output end. The rotation of the rotating shaft 92 drives the warning light 91 to rotate, thereby warning people and vehicles passing by at night, and the battery 94 can power the drive motor 93 and the warning light 91.
