[0002] Dikes and dams are a general term for structures and buildings that prevent water from flowing through them. They are widely used in water conservancy projects. In order to ensure the safety of pedestrians walking on dikes, guardrails are often installed on both sides of the dikes to prevent pedestrians from falling. Guardrails are a kind of protective facility that we can see everywhere in our lives. They are mainly used in residential areas, highways, riverbanks, commercial areas and public places to protect personal safety and equipment.

[0003] A prior art patent application (application number 202321062861.3) describes a protective railing for a hydraulic dam, comprising an installation plate. A fixing bolt is rotatably connected to the interior of the installation plate. The installation plate has an internal groove, and a first sliding groove is formed on the inner top wall of the groove. A fixing rod is fixedly connected to the inner side wall of the first sliding groove, and a connecting block is slidably connected to the outer wall of the fixing rod. A push plate is fixedly connected to the bottom of the connecting block, and a compression ring is fixedly connected to one side of the push plate. A support plate is fixedly connected to the top of the installation plate, and a groove is formed inside the support plate. A fixing block is slidably connected inside the groove, and a protective plate is fixedly connected to one side of the fixing block. An installation groove is formed inside the fixing block. This invention facilitates the installation and fixing of the support plate to prevent loosening, thus improving the safety of the support plate and enhancing its stability. However, during periods of heavy summer rainfall, water can easily overflow from the bottom of the railing, rendering it ineffective for flood control and affecting its functionality. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3In this embodiment of the utility model, a protective railing for a water conservancy dam includes a railing body, which includes a first upright 1 and a second upright 2. An upper fixed horizontal plate 7 and a lower fixed horizontal plate 8 are fixedly arranged between the first upright 1 and the second upright 2. A longitudinal upright plate 9 is provided between the upper fixed horizontal plate 7 and the lower fixed horizontal plate 8, and a plurality of movable horizontal plates 11 are longitudinally slidably arranged in the limiting sliding holes 10 between the longitudinal upright plates 9. This allows the position of the plurality of movable horizontal plates 11 within the limiting sliding holes 10 to be adjusted. When the plurality of movable horizontal plates 11 are moved to the bottom of the railing body, water can be prevented from overflowing the lower fixed horizontal plate 8 for flood control, thus improving the flexibility of the protective use.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, in order to position the movable horizontal plate 11 after adjustment, a limiting groove 12 is provided on one side of the first upright 1 and the second upright 2, and a limiting hole 13 is provided on the side wall of the limiting groove 12. The two ends of the movable horizontal plate 11 are slidably arranged with the limiting groove 12, and the guide rod 14 is slidably arranged in the limiting hole 13. The two ends of the movable horizontal plate 11 are also fixedly connected to the first upright 1 and the second upright 2 through the guide rod 14 and the locking nut 15. The first upright 1 and the second upright 2 are provided with a groove 16 for accommodating the locking nut 15 on one side. The upper wall of the lower fixed horizontal plate 8 is also provided with a third sealing groove 19, which facilitates the stability of the lifting and lowering adjustment of the two ends of the movable horizontal plate 11 on the first upright 1 and the second upright 2, and at the same time facilitates the positioning of the movable horizontal plate 11 after adjustment.

[0027] like Figure 1 and Figure 2 As shown, in order to improve the stability of the installation and fixing between adjacent guardrail bodies, a first sealing groove 3 is provided on one side of the first upright 1, and a first sealing protrusion 4 is provided on one side of the second upright 2. The first sealing protrusion 4 is inserted into the first sealing groove 3. The first sealing groove 3 is a semi-cylindrical groove, and the first sealing protrusion 4 is a semi-cylindrical shape. Multiple sets of the first sealing protrusion 4 and the first sealing groove 3 are provided in parallel, which facilitates the improvement of the stability and sealing of the installation and fixing between adjacent guardrail bodies.

[0028] like Figure 2 and Figure 4As shown, in order to improve the sealing performance when multiple movable horizontal plates 11 are arranged longitudinally, a second sealing groove 17 is provided on one side of the movable horizontal plate 11, and a second sealing protrusion 18 is provided on the lower side of the movable horizontal plate 11. When the second sealing protrusion 18 is engaged in the second sealing groove 17, it is convenient to improve the sealing performance of the longitudinal connection between adjacent movable horizontal plates 11, and at the same time, it is convenient to improve the sealing performance when multiple movable horizontal plates 11 are arranged longitudinally.

[0029] The working principle and usage process of this utility model are as follows: In use, multiple guardrail bodies are installed on the embankment through positioning rods 5 for protection. Multiple movable horizontal plates 11 are longitudinally slidable within the limiting sliding holes 10 between the longitudinal upright plates 9 of the guardrail bodies, so that the position of the multiple movable horizontal plates 11 within the limiting sliding holes 10 can be adjusted. When the multiple movable horizontal plates 11 are moved to the bottom of the guardrail body, they can prevent water from overflowing the lower fixed horizontal plate 8 for flood control. Moreover, when the multiple movable horizontal plates 11 are tightly attached, they have a certain windproof effect, improving the flexibility of protection.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
