Description

Technical Field

[0001] This utility model relates to the field of fence technology, and in particular to a protective fence for water conservancy construction. Background Technology

[0002] Water conservancy projects involve complex and diverse construction environments, including rivers, dams, pumping stations, and sluice gates. Construction often faces challenges such as undulating terrain, changing water flows, and dense operations of personnel and equipment. To ensure construction safety, effective protective facilities are needed to isolate hazardous areas and prevent accidents such as accidental entry of personnel, falling objects, or water impact. While traditional protective fences provide basic protection, they have many limitations in practical applications and cannot meet the high safety requirements of modern water conservancy construction. The height of traditional protective fences is often fixed, making it impossible to flexibly adjust them according to the actual terrain and protection needs of the construction site. For example, in areas near the water's edge and in low-lying areas, fixed-height fences may not effectively block personnel; while in areas with frequent personnel activity, fixed heights may not provide sufficient protective strength. This limitation of fixed height makes protective fences difficult to adapt to diverse construction environments, reducing their protective effectiveness.

[0003] Therefore, in order to address this problem, this utility model provides a protective fence for water conservancy construction. Utility Model Content

DETAILED DESCRIPTION

[0018] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, and not all the embodiments.

[0019] In the description of the utility model, it needs to be understood that the orientation or position relation indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like is the orientation or position relation based on the orientation or position relation shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model.

[0020] Referring to Figures 1-3 A protective fence for water conservancy construction, including fixed rail frame 1, sliding frame 2 is slidably connected with fixed rail frame 1, so that sliding frame 2 can smoothly slide in the top wall of fixed rail frame 1. The top of sliding frame 2 is welded with a plurality of extension rail 3 at equal distance, after these extension rail 3 pass through the reserved hole in the top of fixed rail frame 1, the end is fixedly connected with top rail 4. A plurality of locking screw grooves 5 are provided at equal distance on the side of sliding frame 2, locking screw rod 6 is connected with locking screw groove 5 through thread cooperation, and the position of locking screw groove 5 is arranged on the side of fixed rail frame 1. When the overall height needs to be adjusted, the staff can push sliding frame 2 to slide in fixed rail frame 1, drive extension rail 3 and top rail 4 to move up and down, adjust to the appropriate height, then screw locking screw rod 6 into corresponding locking screw groove 5, so that it abuts against the side of fixed rail frame 1, thereby fixing the position of sliding frame 2, realize height adjustment. This design, on the one hand, facilitates the staff to adjust the overall height according to different water conservancy construction environment, on the other hand, when carrying, sliding frame 2 can be slid to the lowest position, reduce the overall height, facilitate the staff to carry, avoid that the overall size affects the carrying use.

[0021] Among them, the side of fixed rail frame 1 is provided with splicing seat 1 7, and the splicing seat 7 is a convex structure with bolt hole; the other side of fixed rail frame 1 is provided with splicing seat 2 8, and the splicing seat 8 is a concave structure with bolt hole, which is matched with the convex structure of splicing seat 7. When multiple protective fences need to be spliced together, the splicing seat 1 of one protective fence is aligned with the splicing seat 2 of another protective fence, then the fixed bolt 9 is passed through the corresponding bolt holes of the two, and the nut is used for fastening, so that the two protective fences are firmly spliced together, which meets the protection of construction area with different length requirements.

[0022] The bottom of the fixed railing frame 1 is welded with a support frame 10, which is made of metal material with certain strength and stability, such as angle steel, etc.

[0023] The front of the fixed railing frame 1 is pasted with a back-shaped reflective strip 12, which is made of material with high reflective performance, such as reflective film, etc. In the night or in the environment with relatively dark light, the back-shaped reflective strip 12 can reflect the surrounding light, play a warning role, remind the passing pedestrians and vehicles to pay attention to the existence of the protective fence, and avoid the occurrence of safety accidents such as collision.

[0024] The top of the fixed railing frame 1 is symmetrically provided with a plurality of sliding grooves 101, and the size and shape of the sliding grooves 101 are matched with the extension railing 3. The extension railing 3 can smoothly slide along the sliding grooves 101. When the sliding frame 2 slides in the fixed railing frame 1, the extension railing 3 moves up and down in the sliding grooves 101, which ensures the stability and accuracy of the movement of the extension railing 3, and also plays a certain guiding role for the extension railing 3.

[0025] The inner wall of the fixed railing frame 1 is welded with a plurality of bottom railings 102 at equal intervals, and the bottom railings 102 and the extension railings 3 are sequentially and adjacently arranged. The bottom railings 102 and the extension railings 3 jointly constitute the protective main body of the protective fence, which increases the protection range and strength of the protective fence. The bottom railings 102 are fixed on the fixed railing frame 1, which provides stable bottom support for the protective fence, and the extension railings 3 can be adjusted in height according to the needs, and the two are matched with each other to improve the overall performance of the protective fence.
