Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering equipment, specifically a protective railing for water conservancy engineering. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Protective fences are usually installed around water conservancy projects for protection.

[0003] For example, Chinese utility model patents with authorization announcement numbers CN221546583U and CN220504713U disclose guardrails with small contact areas between the bottom and the ground, resulting in poor stability. Under the influence of external forces such as wind and rain commonly encountered in water conservancy engineering areas, they are prone to tilting or even collapsing. Moreover, the tops are designed vertically with simple structures, allowing children to easily climb over them, resulting in poor protection and difficulty in effectively preventing people from accidentally entering dangerous areas.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing protective railings used in water conservancy projects. Utility Model Content

[0005] The purpose of this utility model is to provide a protective railing for water conservancy projects to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guardrail for water conservancy projects, comprising a base plate, a protective mechanism at the top of the base plate, and a stabilizing mechanism at the bottom of the base plate. The protective mechanism includes vertical plates and horizontal bars. Vertical plates are welded and fixed at equal intervals to the top of the base plate, and horizontal bars are welded and fixed at equal intervals between the vertical plates.

[0007] Preferably, the lower half of the vertical plate is designed to be vertically upward, the middle part of the vertical plate is designed to be inclined upward, the upper half of the vertical plate is designed to be arc-shaped, and the opening of the upper half of the vertical plate and the lowest point of the middle part of the vertical plate are designed to face the protective area.

[0008] Preferably, the stabilizing mechanisms are evenly distributed at the bottom of the base plate.

[0009] Preferably, the stabilizing mechanism includes a circular plate. The bottom of the base plate is fixed to the circular plate by a first bolt. The upper end of a vertical rod is welded and fixed to the center of the bottom of the circular plate. A first docking seat is welded and fixed to the side of the lower end of the vertical rod. A first docking groove is formed inside one side of the first docking seat away from the vertical rod. One end of a first support plate is engaged inside the first docking groove. The first docking seat and one end of the first support plate are fixedly connected by a second bolt. The other end of the first support plate is engaged inside a second docking groove. The second docking groove is formed inside one side of the second docking seat. The second docking seat and the other end of the first support plate are fixedly connected by a third bolt. One end of the second docking seat away from the first support plate is welded and fixedly connected to the middle of the inner side of the second support plate.

[0010] Preferably, the second support plate is designed as an arc-shaped structure, and both the first and second support plates are distributed at equal angles about the central axis of the vertical rod.

[0011] Preferably, the first bolt is slidably connected to the inside of the side of the circular plate, and the upper end of the first bolt is threaded to the inside of the base plate. The first bolts are distributed at equal angles about the central axis of the circular plate. The second bolt is slidably connected to the top of the first mating seat, and the lower end of the second bolt is threaded to one end of the first support plate. The third bolt is slidably connected to the top of the second mating seat, and the lower end of the third bolt is threaded to the other end of the first support plate.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This guardrail for water conservancy projects is equipped with a protective mechanism consisting of vertical plates and horizontal bars, and a stabilizing mechanism consisting of circular plates, vertical bars, a first support plate, and a second support plate, which solves the problems of poor stability and insufficient protection of existing guardrails. Specifically, the protective mechanism, through the special three-section design of the vertical plates—a vertical section, an inclined section, and an arc-shaped section—effectively prevents children from climbing over and improves protective performance. The stabilizing mechanism, through its multi-directionally unfolding support plate structure, significantly increases the contact area with the ground and the support strength, ensuring that the guardrail remains stable under the action of external forces such as wind and rain, and is not easily tilted or collapsed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-7 This utility model provides a technical solution: a guardrail for water conservancy projects, including a base plate 1, a protective mechanism on the top of the base plate 1, and a stabilizing mechanism on the bottom of the base plate 1. The protective mechanism includes vertical plates 2 and horizontal bars 3. Vertical plates 2 are welded and fixed at equal intervals on the top of the base plate 1, and horizontal bars 3 are welded and fixed at equal intervals between the vertical plates 2.

[0023] The lower half of the vertical board 2 is designed to be vertically upward, the middle part of the vertical board 2 is designed to be inclined upward, and the upper half of the vertical board 2 is designed to be arc-shaped. The opening of the upper half of the vertical board 2 and the lowest point of the middle part of the vertical board 2 are designed to face the protective area. This design makes the vertical board 2 form a complex non-continuous vertical structure. The inclined section in the middle and the arc-shaped design of the upper half increase the difficulty of climbing, effectively prevent children from climbing over, and improve the protective performance.

[0024] The stabilizing mechanisms are evenly distributed at the bottom of the base plate 1. The evenly distributed stabilizing mechanisms can make the force on each area of ​​the base plate 1 uniform, avoid tilting caused by excessive local force, and further enhance the overall stability.

[0025] The stabilizing mechanism includes a circular plate 4. The bottom of the base plate 1 is fixed to the circular plate 4 by a first bolt 5. The upper end of a vertical rod 6 is welded and fixed to the center of the bottom of the circular plate 4. A first mating seat 7 is welded and fixed to the side of the lower end of the vertical rod 6. A first mating groove 8 is formed inside one side of the first mating seat 7 away from the vertical rod 6. One end of a first support plate 9 is engaged inside the first mating groove 8. The first mating seat 7 and one end of the first support plate 9 are fixedly connected by a second bolt 10. The other end of the first support plate 9 is engaged inside a second mating groove 11. The second mating groove 11 is formed at the first Inside one side of the second docking seat 12, the other end of the second docking seat 12 and the first support plate 9 are fixedly connected by the third bolt 13. One end of the second docking seat 12, away from the first support plate 9, is welded and fixedly connected to the middle of the inner side of the second support plate 14. The stable mechanism formed by the multi-layer docking structure can greatly increase the contact area between the guardrail and the ground. The vertical bar 6 extends into the ground to provide vertical support. The first support plate 9 and the second support plate 14 unfold in the horizontal direction to form a stable support surface, which solves the problem of poor stability caused by the small bottom contact area of ​​traditional guardrails.

[0026] The second support plate 14 is designed with an arc-shaped structure. The first support plate 9 and the second support plate 14 are both distributed at equal angles about the central axis of the vertical rod 6. The arc-shaped second support plate 14 can better fit the ground contour and distribute the force. The first support plate 9 and the second support plate 14, which are distributed at equal angles, can form a stable support in all directions and resist the impact of external forces from different directions.

[0027] The first bolt 5 is slidably connected to the inside of the side of the circular plate 4, and the upper end of the first bolt 5 is threaded to the inside of the base plate 1. The first bolt 5 is equidistantly distributed about the central axis of the circular plate 4. The second bolt 10 is slidably connected to the top of the first mating seat 7, and the lower end of the second bolt 10 is threaded to one end of the first support plate 9. The third bolt 13 is slidably connected to the top of the second mating seat 12, and the lower end of the third bolt 13 is threaded to the other end of the first support plate 9. The equidistant distribution of multiple bolts ensures that the force at each connection point is uniform. The threaded connection method ensures that the components are firmly connected, and at the same time facilitates installation, disassembly, and subsequent maintenance and replacement.

[0028] Working principle: When using this hydraulic engineering guardrail, the first step is installation and fixation. First, dig a suitable-sized pit at the installation location (the depth is determined by the length of the vertical pole 6, ensuring that the first support plate 9 and the second support plate 14 can be completely placed inside the pit). Place the assembled stabilizing mechanism into the pit, unfold the first support plate 9 and the second support plate 14 so that they are laid out radially at the bottom of the pit, ensuring the second support plate 14 is placed stably. Then, fill the pit with soil, compacting it in layers until the soil completely covers the first support plate 9, the second support plate 14, and the vertical pole 6, leaving only the bottom plate 1 exposed.

[0029] The connection points between the first support plate 9 and the first docking seat 7 and the second docking seat 12 are secured by the second bolt 10 and the third bolt 13, respectively, ensuring that the components of the stabilizing mechanism will not loosen under the cover of soil. At this time, the first support plate 9 and the second support plate 14, which are buried in soil, are tightly combined with the surrounding soil, forming a "anchor-like" fixing effect, which greatly increases the bonding force between the guardrail and the ground. Combined with the vertical support of the vertical bar 6, it effectively solves the problem of small contact area and unstable fixation at the bottom of traditional guardrails, and can maintain overall stability even when encountering strong winds or water flow impacts.

[0030] During operation, the protective mechanism consisting of vertical panels 2 and horizontal bars 3 acts as an isolation barrier. The lower vertical section of vertical panel 2 forms a basic barrier, while the sloping middle section and the arc-shaped upper section make it difficult for climbers to gain leverage, structurally blocking the climbing path and effectively preventing children from climbing over, thus solving the problem of poor protection in traditional guardrails. The horizontal bars 3 strengthen the connection between the vertical panels 2, improving the overall impact resistance of the protective mechanism and ensuring that the guardrail can stably perform its protective function for a long time.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
