Technical Field

[0001] The utility model relates to a protective device, in particular to a protective device for water conservancy and hydropower engineering, belonging to the technical field of protective equipment. Background Art

[0002] In water conservancy projects, guardrails are usually set up on the edges of some dams and reservoirs to intercept unauthorized personnel from approaching to avoid dangers such as falling into the water. Current protective fences generally achieve interception and protection through criss-crossing columns. Although this type of guardrail has a simple structure, it is easy for people to climb over it, and it cannot play the protective role it should.

[0003] Therefore, it is urgent to improve the protective devices used in water conservancy and hydropower projects to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a protective device for water conservancy and hydropower engineering projects. After the sliding cylinder is subjected to the force of people climbing up, the first spring will be compressed to move downward, thereby failing to provide stable supporting force for the people. Moreover, if the climbing people hold the rotating column to climb up, the rotating column will rotate due to the force, making it difficult for the people to exert force and unable to climb, thereby achieving better protective effect.

[0005] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include: two columns and a horizontal plate connected between the lower ends of the two columns, the horizontal plate is provided with a plurality of intercepting members arranged parallel to the columns, a rotating column is rotatably connected between the upper ends of the two columns, the intercepting member includes a vertical pole, a fixed cylinder sleeved on the outside of the vertical pole and a sliding cylinder slidably connected to the inside of the fixed cylinder, a receiving seat is slidably connected to the inside of the fixed cylinder, and a first spring is connected between the upper end of the receiving seat and the bottom of the sliding cylinder.

[0006] Preferably, it also includes a warning component, which includes a warning piece arranged at the upper end of the column and a trigger switch electrically connected to the warning piece, the trigger switch is installed on the lower end surface of the receiving seat, and a second spring is connected between the bottom end of the receiving seat and the cross plate.

[0007] Preferably, the stiffness of the second spring is greater than the stiffness of the first spring.

[0008] Preferably, an arc-shaped supporting seat is provided at the top end of the vertical rod, and the inner concave surface of the arc-shaped supporting seat is in contact with the outer wall of the rotating column.

[0010] Preferably, the receiving seat and the transverse plate are both provided with water leakage holes.

[0011] The utility model has at least the following beneficial effects:

[0012] 1. When a person needs to hold the sliding cylinder above to climb, the sliding cylinder will compress the first spring and move downward after receiving the force of the person climbing upward, thereby failing to provide stable support for the person. Moreover, if the climber holds the rotating column to climb upward, the rotating column will rotate due to the force, making it difficult for the person to exert force and unable to climb, thus achieving better protection effect.

DETAILED DESCRIPTION

[0021] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figure 1-Figure 5As shown, the protective device for water conservancy and hydropower engineering provided in this embodiment includes two columns 1 and a horizontal plate 11 connected between the lower ends of the two columns 1. The horizontal plate 11 is provided with a plurality of intercepting members 2 arranged parallel to the columns 1. The density of the intercepting members 2 can be set according to the length of the horizontal plate 11, and the distance between two adjacent intercepting members 2 is preferably 10-15 cm to prevent people from passing between two adjacent intercepting members 2. The length of the horizontal plate 11 can be customized. During installation, the two columns 1 can first be fixedly connected at a designated position by expansion bolts or concrete pouring, and then the horizontal plate 11 can be fixedly connected between the two columns 1;

[0023] Specifically, the intercepting member 2 includes a vertical rod 21, a fixed tube 22 sleeved on the outside of the vertical rod 21, and a sliding tube 23 slidably connected to the inside of the fixed tube 22. The central axes of the vertical rod 21, the sliding tube 23 and the fixed tube 22 coincide with each other. A receiving seat 24 is slidably connected to the inside of the fixed tube 22. A first spring 25 is connected between the upper end of the receiving seat 24 and the bottom of the sliding tube 23. When a person climbs, the person can hold the sliding tube 23 by his own height. When climbing upward, a downward pulling force is generated on the sliding tube 23. The sliding cylinder 23 compresses the first spring 25 to move downward, thereby failing to provide a force point for people to climb, wherein a rotating column 3 is rotatably connected between the upper ends of the two columns 1. If a person slides the sliding cylinder 23 to the lowest end and climbs by stepping on the upper end surface of the sliding cylinder 23, he needs to climb by holding the rotating column 3, and the rotating column 3 will be subjected to force and will rotate, making it difficult for people to apply force and unable to climb, thereby achieving better protection effect. The rotating column 3 can be customized according to the distance between the two columns 1, just like the horizontal plate 11.

[0024] Further, such as Figure 4 As shown, a plurality of friction cones 6 are provided on the outer wall of the upper end of the vertical pole 21. When the sliding cylinder 23 is subjected to the force of compressing the spring and moves downward, the friction cone 6 will be exposed on the outer surface of the vertical pole 21. When a person mechanically holds the vertical pole 21 to climb, a certain squeezing force will be generated on the person's arm through the friction column, which is similar to the effect of a finger pressure plate, causing discomfort in the person's hand and making it impossible to climb. At the same time, if the sliding cylinder 23 is not affected by external force, the sliding cylinder 23 will be pushed upward under the elastic force of the first spring 25, so that the sliding cylinder 23 moves to the outside of the upper end of the vertical pole 21, forming a protection on the outside of the friction cone 6 to prevent people from accidentally touching the friction cone 6.

[0025] Further, such as Figure 2As shown, an arc-shaped supporting seat 5 is provided at the top of the vertical rod 21, and the inner concave surface of the arc-shaped supporting seat 5 fits with the outer wall of the rotating column 3. The arc-shaped supporting seat 5 can support and bear the rotating column 3 at the bottom of the rotating column 3, so that the rotating column 3 has better stability. At the same time, it can intercept at the upper end of the column 1, so that people cannot climb the upper end of the column 1 to climb over the guardrail.

[0026] Further, such as Figure 1 as well as Figure 5 As shown, it also includes a warning component, which includes a warning piece 4 arranged at the upper end of the column 1 and a trigger switch 41 electrically connected to the warning piece 4. The warning piece 4 can be a warning light, a buzzer alarm or a warning device combining a warning light and a buzzer alarm. When the trigger switch 41 is pressurized, the warning piece 4 is turned on. The trigger switch 41 is installed on the lower end surface of the receiving seat 24, and a second spring 42 is connected between the bottom end of the receiving seat 24 and the cross plate 11. When the sliding cylinder 23 is slid to the bottom, if the person continues to step on the upper end of the sliding cylinder 23, at this time, the sliding cylinder 23 will drive the receiving seat 24 to compress the second spring 42 through the first spring 25. When the receiving seat 24 moves downward and drives the trigger switch 41 to come into contact with the bottom of the cross plate 11, the warning piece 4 is turned on to attract the attention of surrounding personnel or warn the climber to stop climbing.

[0027] Further, such as Figure 1 As shown, the stiffness of the second spring 42 is greater than that of the first spring 25. If the first spring 25 is compressed by only generating a certain force on the sliding cylinder 23, the second spring 42 will not be compressed synchronously. A certain supporting force is generated on the receiving seat 24 and the sliding cylinder 23 by the second spring 42, so that the warning member 4 will not issue a warning due to the random downward movement of the sliding cylinder 23, but will issue a warning when the sliding cylinder 23 is subjected to a certain pressure, indicating that someone has stepped on the sliding cylinder 23 to climb.

[0028] Further, such as Figure 5 As shown, the receiving seat 24 and the cross plate 11 are both provided with leakage holes 7. When rainwater enters from the upper end of the sliding cylinder 23 in rainy and snowy weather, the rainwater can be discharged from the bottom of the cross plate 11 through the leakage holes 7, thereby preventing rainwater from accumulating in the sliding cylinder 23 and the fixed cylinder 22.

[0029] like Figure 1-Figure 5As shown, the principle of the protective device for water conservancy and hydropower engineering provided by this embodiment is as follows: when in use, the column 1 is installed at the specified position, and then the cross plate 11 is connected between the two columns 1. When a person climbs, he needs to hold the sliding cylinder 23 with both hands and move downward, and the sliding cylinder 23 will compress the first spring 25 to move downward, and then the friction cone 6 on the vertical pole 21 will be exposed to the outside. If the person still holds the upper end of the vertical pole 21 to climb, he needs to hold the friction cone 6. The friction cone 6 will cause discomfort to the person's hand, making it impossible for the person to hold the column 1 tightly. When the person is climbing, if he wants to hold the rotating column 3, the rotating column 3 will rotate when it is subjected to force, making it difficult for the person to apply force and unable to climb, and the protective effect is better.
