DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] Please refer to Figures 1-5 The utility model provides a technical scheme:

[0025] A water conservancy and hydropower engineering concrete dam body guardrail, comprising a dam body 1, the upper end of the dam body 1 is provided with a fixed column 2, the two ends of the fixed column 2 are provided with a plurality of connecting rods 3, the connecting rods 3 are connected with guardrails 4, the two ends of the guardrails 4 are provided with connecting holes 5, and the outer ends of the connecting rods 3 are connected with connecting sleeves 6 through threads.

[0026] In this embodiment, the front end of the preferred railing 4 is provided with several fixed sleeves 7, and the interior of the fixed sleeve 7 is provided with a telescopic spring 8. The telescopic spring 8 has a certain elastic force. When the guardrail 10 is impacted by the water flow, it will absorb part of the impact force to prevent the guardrail 10 from being damaged.

[0027] In this embodiment, a telescopic rod 9 is preferably provided at the front end of the telescopic spring 8, and a guardrail 10 is provided at the end of the telescopic rod 9 away from the telescopic spring 8. The guardrail 10 is easily fixed by the telescopic rod 9. The guardrail 10 can play a certain protective role to prevent pedestrians from falling into the reservoir.

[0028] In this embodiment, a water guide groove 11 is preferably provided at the end of the guardrail 10 away from the telescopic rod 9. The water guide groove 11 is an arc-shaped structure. When the water flow hits the guardrail 10, the water flow will flow along the arc-shaped water guide groove 11, thereby buffering part of the force and preventing the water flow from directly hitting the guardrail 10, so that the guardrail 10 is only subjected to part of the force, thereby preventing the guardrail 10 from being damaged.

[0029] In this embodiment, the lower end of the preferred fixed column 2 is provided with a fixed base 12, and the lower end of the fixed base 12 is provided with two reinforcing rods 13, and the upper end of the fixed base 12 is connected with a fixing bolt 14 through a thread. When installing the guardrail on the dam body 1, the reinforcing rod 13 at the lower end of the fixed column 2 is first embedded in the concrete foundation, and then the fixed base 12 is fixed to the dam body 1 by the fixing bolts 14, so that the fixed column 2 is firmly fixed, thereby improving the stability of the guardrail.

[0030] In this embodiment, the upper end of the connecting rod 3 is preferably provided with an external thread, and the interior of the connecting sleeve 6 is provided with a thread, so that the connecting rod 3 and the connecting sleeve 6 can be threadedly connected.

[0031] When installing a guardrail on the dam body 1 of a concrete dam body of a water conservancy and hydropower project in this embodiment, first, the reinforcing rod 13 at the lower end of the fixing column 2 is pre-buried in the concrete foundation, and then the fixing base 12 is fixed to the dam body 1 by the fixing bolts 14, so that the fixing column 2 is firmly fixed, thereby improving the stability of the guardrail. Then, the connecting hole 5 on the railing 4 is aligned with the connecting rod 3 and is sleeved on the connecting rod 3, and then the connecting sleeve 6 is sleeved on the connecting rod 3 and tightened. The guardrail is installed under the squeezing action of the connecting sleeve 6. When the guardrail is damaged, it is only necessary to find the damaged section, and then The connecting sleeve 6 can be removed by rotating it in the opposite direction, thereby loosening the fixation on the guardrail, making it easier to remove the guardrail and replace it with a new one. When the water flow hits the guardrail plate 10 during use of the guardrail, the water flow will flow along the arc-shaped water guide groove 11, thereby buffering part of the force and preventing the water flow from directly hitting the guardrail plate 10, so that the guardrail plate 10 is only subjected to part of the force, thereby preventing the guardrail plate 10 from being damaged. At the same time, through the coordinated arrangement of the fixing sleeve 7, the telescopic spring 8 and the telescopic rod 9, when the guardrail plate 10 is impacted by the water flow, it will absorb part of the impact force to prevent the guardrail plate 10 from being damaged.

[0032] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
