Description

Technical Field

[0001] This utility model relates to the field of water conservancy protection technology, specifically to a retractable water conservancy protection fence. Background Technology

[0002] Water conservancy protection barriers are safety protection facilities set up around water conservancy projects, such as the edges of water bodies like rivers, reservoirs, and canals. They are mostly made of sturdy materials such as metal or concrete. Through physical isolation and warning signs, they prevent people from entering the water conservancy project area and can also block debris from entering the water body, thus protecting water conservancy facilities and having the functions of safety protection and maintaining the order of the water conservancy environment.

[0003] A search revealed Chinese Patent Publication No. CN219754247U, which discloses a water conservancy protective railing, including a flood control base. Rust-proof nuts are fixedly connected to the four corners of the flood control base, and a flood control column assembly is fixedly connected to the upper surface of the flood control base. By using this structure, the direct impact of water waves can be buffered to a certain extent, effectively preventing damage to the railing. Furthermore, damaged parts of the railing can be disassembled individually, thereby reducing replacement costs.

[0004] Existing technologies often have the following problems when used:

[0005] Currently used water conservancy guardrails are usually of fixed width and size, making it difficult to change and adjust the protection width of the guardrails according to different water conservancy facility scenarios, water widths, and protection range requirements. This results in poor applicability of water conservancy guardrails and an inability to meet diverse protection needs. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a retractable hydraulic protection fence, which can effectively solve the problem that the existing hydraulic protection fences are usually fixed in width and size, making it inconvenient to change and adjust their protection width, thus limiting the use of the hydraulic protection fence.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a retractable hydraulic safety barrier, including:

[0009] An upper protective frame and a lower protective frame, wherein a number of central support rails are fixedly connected between the upper protective frame and the lower protective frame;

[0010] The telescopic variable pitch assembly includes two lower telescopic frames slidably connected to the inner wall of the lower protective frame, two upper telescopic frames slidably connected to the inner wall of the upper protective frame, a lateral support rail fixedly connected between the upper telescopic frames and the lower telescopic frames located on the same side, and a telescopic drive component fixedly connected to the inner wall of the lower protective frame, the telescopic drive component being used to drive the two lower telescopic frames to telescopically move relative to the lower protective frame.

[0011] Both of the upper telescopic frames have adjustable protective components slidably connected to their outer walls.

[0012] Furthermore, the telescopic drive component includes two support frames fixedly connected to the inner wall of the lower telescopic frame. Each of the two support frames is rotatably connected to an adjusting screw. The threads on the two adjusting screws are in opposite directions, and each of the two adjusting screws is threadedly connected to a slider. The ends of the two lower telescopic frames located inside the lower protective frame are respectively fixedly connected to the two sliders. A dual-axis motor is fixedly installed on the inner wall of the lower protective frame, and the two output ends of the dual-axis motor are respectively fixedly connected to the ends of the two adjusting screws.

[0013] Furthermore, the adjustable protective assembly includes a plurality of first rectangular plates slidably connected to the outer wall of the upper telescopic frame, a plurality of second rectangular plates slidably connected to the outer wall of the lower telescopic frame, a plurality of adjustable support rails fixedly connected between the plurality of first rectangular plates and the plurality of second rectangular plates, and disassembly and assembly components fixedly connected to the outer walls of the plurality of first rectangular plates and the plurality of second rectangular plates.

[0014] Furthermore, the disassembly and assembly components include internally threaded sleeves fixedly connected to the outer walls of rectangular plates No. 1 and No. 2. The inner side of the internally threaded sleeve is threadedly connected to a fastening screw. The side walls of the upper telescopic frame and the lower telescopic frame are provided with several threaded insertion holes, and the fastening screw is threadedly engaged with the threaded insertion holes.

[0015] Furthermore, a knob is fixedly connected to the end of the fastening screw away from the internal threaded sleeve.

[0016] Furthermore, the lower end face of the lower protective frame and the lower end faces of the two lower telescopic frames are all fixedly connected with grounding pins.

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] This utility model incorporates a telescopic variable-pitch component. By driving two sliders to move in opposite directions or back to back, two lower telescopic frames are moved, allowing them to synchronously extend and retract relative to the lower protective frame. During the telescopic movement of the lower telescopic frames, the upper telescopic frame can be moved and retracted relative to the upper protective frame via the lateral support rails. This enables the overall width of the guardrail to be adjusted, thereby improving the applicability of the hydraulic guardrail and meeting diverse protection needs.

[0019] This utility model is equipped with an adjustable protective component. By pushing the adjustable support railing to move, the first rectangular plate and the second rectangular plate can slide freely relative to the upper and lower telescopic frames, respectively. After the protective railing is adjusted to a suitable position, the first rectangular plate, the second rectangular plate, and the adjustable support railing are fully fixed to adjust the protective density of the water conservancy protective railing and further improve its applicability.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 3 The retractable hydraulic guardrail includes: an upper guardrail 1, a lower guardrail 2, and a telescopic variable pitch assembly. Several central support rails 3 are fixedly connected between the upper guardrail 1 and the lower guardrail 2. The telescopic variable pitch assembly includes two lower telescopic frames 4 that are slidably connected to the inner wall of the lower guardrail 2. Grounding fixing pins 18 are fixedly connected to the lower end face of the lower guardrail 2 and the lower end face of the two lower telescopic frames 4. Two upper telescopic frames 5 are slidably connected to the inner wall of the upper guardrail 1. Lateral support rails 6 are fixedly connected between the upper telescopic frame 5 and the lower telescopic frame 4 on the same side.

[0028] A telescopic drive component is fixedly connected to the inner wall of the lower protective frame 2. The telescopic drive component is used to drive the two lower telescopic frames 4 to telescopically move relative to the lower protective frame 2. The telescopic drive component includes two support frames 7 fixedly connected to the inner wall of the lower telescopic frames 4. Each of the two support frames 7 is rotatably connected to an adjusting screw 8. The threads on the two adjusting screws 8 are in opposite directions, and each of the two adjusting screws 8 is threadedly connected to a slider 9. The ends of the two lower telescopic frames 4 located inside the lower protective frame 2 are fixedly connected to the two sliders 9 respectively. A dual-axis motor 10 is fixedly installed on the inner wall of the lower protective frame 2. The dual-axis motor 10 is a horizontal dual-axis motor of model CHD-2. The two output ends of the dual-axis motor 10 are fixedly connected to the ends of the two adjusting screws 8 respectively.

[0029] By driving two sliders 9 to move in opposite or opposite directions along the two adjusting screws 8, the two lower telescopic frames 4 are moved, so that the two lower telescopic frames 4 can move synchronously relative to the lower protective frame 2. When the lower telescopic frames 4 move in and out, they can drive the upper telescopic frame 5 to move in and out relative to the upper protective frame 1 through the side support rail 6. This allows for the overall width of the guardrail to be adjusted, so as to adjust the overall protective width of the guardrail, improve the applicability of the water conservancy guardrail, and meet diverse protection needs.

[0030] Specifically, since the threads on the two adjusting screws 8 are in opposite directions, when the two adjusting screws 8 are driven to rotate in the same direction, the two sliders 9 can move in opposite directions or away from each other under the threaded rotational engagement with the two adjusting screws 8 respectively. Furthermore, the lower protective frame 2 and the two lower telescopic frames 4 are both set with a rectangular frame structure. The two lower telescopic frames 4 are in contact with the lower protective frame 2 and slide in engagement, thereby ensuring the movement stability of the two lower telescopic frames 4 and realizing the synchronous telescopic movement of the two lower telescopic frames 4 relative to the lower protective frame 2.

[0031] Specifically, the outer surface of the lower protective frame 2 and the inner surface of the lower telescopic frame 4 are coated with a metal sealing coating. When the lower telescopic frame 4 slides relative to the lower protective frame 2, it can prevent water from entering the interior of the lower protective frame 2. At the same time, the drive components and transmission structure inside the lower protective frame 2 are coated with a waterproof coating to ensure the normal operation of the telescopic drive components.

[0032] Both upper telescopic frames 5 have adjustable protective components slidably connected to their outer walls. The adjustable protective components include several first rectangular plates 11 slidably connected to the outer walls of the upper telescopic frames 5. Several second rectangular plates 12 are slidably connected to the outer walls of the lower telescopic frames 4. Several adjustable support rails 13 are fixedly connected between the first rectangular plates 11 and the second rectangular plates 12. The outer walls of the first rectangular plates 11 and the second rectangular plates 12 are fixedly connected to disassembly and assembly components. The disassembly and assembly components include internally threaded sleeves 14 fixedly connected to the outer walls of the first rectangular plates 11 and the second rectangular plates 12. The inner side of the internally threaded sleeves 14 is threadedly connected to a fastening screw 15. The end of the fastening screw 15 away from the internally threaded sleeve 14 is fixedly connected to a knob 17. Several threaded insertion holes 16 are opened on the side walls of the upper telescopic frames 5 and the lower telescopic frames 4. The fastening screw 15 is threadedly engaged with the threaded insertion holes 16.

[0033] If it is necessary to adjust the protective density after the protective width of the guardrail is adjusted, the adjustable support railing 13 can be moved so that the first rectangular plate 11 and the second rectangular plate 12 can slide freely relative to the upper telescopic frame 5 and the lower telescopic frame 4 respectively. After the guardrail is adjusted to the appropriate position, the fastening screw 15 is driven to rotate by rotating the knob 17, so that the fastening screw 15 gradually engages with the threaded insertion hole 16 and is fully inserted into the threaded insertion hole 16, so as to fully fix the first rectangular plate 11, the second rectangular plate 12 and the adjustable support railing 13, thereby realizing the adjustment of the protective density of the water conservancy guardrail and further improving the applicability of the water conservancy guardrail.

[0034] Specifically, if the adjustable support railing 13 obstructs the telescopic movement of the upper telescopic frame 5 and the lower telescopic frame 4 before adjusting the guardrail width, the fastening screw 15 can be rotated in the opposite direction to release the fixed position of the adjustable support railing 13.

[0035] Specifically, the protective density of the guardrail refers to the protective density of the retractable part of the guardrail, that is, the protective density of the part between the central support railing 3 and the side support railing 6. During the installation of the guardrail, after the protective width and protective density of the guardrail are adjusted, the grounding fixing pin 18 can be inserted into the ground to install and fix the guardrail. After several grounding fixing pins 18 are grounded, the overall stability of the guardrail can be effectively enhanced.

[0036] The working principle of this utility model is as follows:

[0037] When in use, if it is necessary to adjust the overall protection width of the guardrail according to the needs of the water conservancy protection range, the dual-axis motor 10 can be started. The dual-axis motor 10 drives the two adjusting screws 8 to rotate, so that the two sliders 9 can move in opposite directions or away from each other along the axis of the two adjusting screws 8. This can drive the two lower telescopic frames 4 to move, so that the two lower telescopic frames 4 can move synchronously relative to the lower protective frame 2. When the lower telescopic frames 4 move in and out, they can drive the upper telescopic frame 5 to move relative to the upper protective frame 1 through the side support rail 6, so as to realize the adjustment of the overall width of the guardrail.

[0038] After adjusting the overall protective width of the guardrail, if it is necessary to adjust the protective density after the adjustment of the protective width, the adjustable support railing 13 can be moved so that the first rectangular plate 11 and the second rectangular plate 12 can slide freely relative to the upper telescopic frame 5 and the lower telescopic frame 4 respectively. After the guardrail is adjusted to a suitable position, the fastening screw 15 is driven to rotate by rotating the knob 17, so that the fastening screw 15 gradually engages with the threaded insertion hole 16 and is fully inserted into the threaded insertion hole 16, so as to fully fix the first rectangular plate 11, the second rectangular plate 12 and the adjustable support railing 13, so as to realize the adjustment of the protective density of the water conservancy guardrail.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
