Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a protective railing for water conservancy projects. Background Technology
[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Guardrails are structural facilities set at the boundaries of specific areas for blocking, warning and protection. They are usually composed of components such as railings and posts. In water conservancy projects, such as around rivers, reservoirs and canals, guardrails are widely used to ensure the safety of people, prevent accidents and play a certain role in protecting water conservancy facilities.
[0003] The existing guardrail for water conservancy projects has the following shortcomings:
[0004] The existing guardrails used in water conservancy projects usually adopt a relatively fixed connection method, such as welding or using a large number of complex bolts and nuts to connect the guardrail posts and the guardrail. This connection method requires a lot of time to align the parts and tighten the numerous connecting parts during installation, which is cumbersome. When it is necessary to repair, replace parts or rearrange the guardrail, the dismantling process is also extremely difficult, requiring the use of professional tools and a lot of effort to complete, which seriously affects work efficiency.
[0005] Meanwhile, most existing guardrails are installed at fixed angles, which cannot be flexibly adjusted according to the complex and ever-changing terrain of water conservancy projects. For example, at river bends or undulating areas at the edge of reservoirs, guardrails cannot conform well to the terrain, resulting in blind spots in protection and failing to fully play their protective role. Furthermore, the terrain may cause uneven stress on the guardrails, reducing their service life. Utility Model Content
[0006] This utility model proposes a protective fence for water conservancy projects. Through the cooperation of positioning and connecting components, it enables quick assembly and disassembly of the fence posts and protective fence. During installation, the insertion post is inserted into the connecting slot, and the spring is tightened to make the right-angle insertion post slide into the positioning slot for fixation. During disassembly, the slider is controlled to move the sliding plate upwards. Simultaneously, the connecting component can also adjust the angle of the protective fence to adapt to complex terrain, improving practicality and solving the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a protective fence for water conservancy projects, comprising several fence posts, wherein a protective fence is fixedly installed on the opposite sides of two adjacent fence posts, and connecting components are provided on the left and right sides of the outer surface of the protective fence.
[0008] The fence support includes a support column, the bottom of which is fixedly connected to a fixing seat. The support column has connection slots on both the left and right sides of its outer surface, and positioning components are provided on both the upper and lower sides of its interior.
[0009] The positioning component includes a cross-shaped sliding groove. Two cross-shaped sliding grooves are respectively opened on the upper and lower sides of the inside of the fence post. A sliding guide post is fixedly connected to the middle of the cross-shaped sliding groove. A sliding plate is slidably connected to the outer surface of the sliding guide post. A clamping spring is fixedly connected to the top of the sliding plate. The clamping spring is set on the outer surface of the sliding guide post. Right-angle inserts are fixedly connected to the left and right sides of the sliding plate. Insertion posts are slidably inserted into the inner surface of the connecting slot. A positioning slot with vertical penetration is opened inside the insertion post. The bottom end of the right-angle insert extends into the inside of the connecting slot and is slidably connected to the inner surface of the positioning slot.
[0010] Preferably, the bottom end of the support column is fixedly connected to a fixing seat, and the fixing seat is fixed to the ground by bolts.
[0011] Preferably, the sliding plate is fixedly connected to connecting columns on both the front and rear sides, the connecting columns extend through to the outer surface of the support column and are fixedly connected to control sliders, and the control sliders are slidably connected to the outer surface of the support column.
[0012] Preferably, the protective fence includes a ring-shaped support rod, and a plurality of isolation rods are fixedly connected to the inner surface of the ring-shaped support rod.
[0013] Preferably, the outer surface of the isolation rod has two annular slots on both the left and right sides, and the inner surface of the annular slots has a plurality of positioning slots arranged in an annular array.
[0014] Preferably, the connecting assembly includes an arc-shaped clamp, the outer surface of which is fixedly connected to the end of the plug-in post away from the connecting slot.
[0015] Preferably, the front and rear sides of the arc-shaped clamping plate are provided with threaded holes that pass through from left to right, and the inner surface of the arc-shaped clamping plate is rotatably connected to one side of the inner surface of the annular groove.
[0016] Preferably, an arc-shaped clamping plate two is provided on the side of the arc-shaped clamping plate one away from the insertion post. The inner surface of the arc-shaped clamping plate two is rotatably connected to the other side of the inner surface of the annular groove and a positioning plate is fixedly connected thereto. The positioning plate is slidably engaged inside the positioning groove.
[0017] Preferably, a knob is rotatably connected to the outer surface of the second arc-shaped clamp, and a movable groove is provided inside the second arc-shaped clamp. The end of the knob near the second arc-shaped clamp extends into the movable groove and is fixedly connected to a drive wheel.
[0018] Preferably, driven wheels are meshed on both the front and rear sides of the outer surface of the driving wheel. The two driven wheels are movably connected to the front and rear sides of the interior of the movable groove, respectively. A transmission screw is fixedly connected to the side of the driven wheel near the first arc-shaped clamping plate. The transmission screw passes through to the side of the second arc-shaped clamping plate near the first arc-shaped clamping plate and is threadedly connected to the inner surface of the threaded hole.
[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0020] 1. In this utility model, through the mutual cooperation between the cross groove, sliding guide post, sliding plate, tightening spring, and right-angle plug in the positioning component and the arc-shaped clamp, plug-in post, and positioning slot in the connecting component, quick assembly and disassembly between the fence post and the protective fence can be achieved. When the protective fence needs to be installed, the plug-in post on the connecting component is inserted into the connecting slot of the fence post, and the tightening spring pushes the sliding plate, so that the right-angle plug-in post automatically slides into the positioning slot to complete the positioning and fixing. The operation is simple and quick. When disassembling, by controlling the slider to drive the sliding plate to move up, the right-angle plug-in post is disengaged from the positioning slot, and the plug-in post can be easily pulled out, realizing quick disassembly and greatly improving the work efficiency of fence installation and maintenance.
[0021] 2. In this utility model, the interplay between the arc-shaped clamping plate one, arc-shaped clamping plate two, positioning plate, positioning slot, knob, driving wheel, driven wheel, and transmission screw in the connecting assembly facilitates angle adjustment of the installed protective fence to adapt to different water conservancy engineering terrains. Rotating the knob drives the driving wheel to rotate, which in turn drives the driven wheel to rotate, causing the transmission screw to move within the threaded hole, thereby adjusting the distance between arc-shaped clamping plate one and arc-shaped clamping plate two, releasing the locking state between the positioning plate and the positioning slot. At this point, the protective fence can be rotated to a suitable angle, and then the knob can be rotated in the opposite direction to re-lock the positioning plate into the corresponding positioning slot, completing the angle fixation. This allows the protective fence to flexibly adapt to complex terrains in water conservancy engineering, such as river bends and undulating terrain, better fulfilling its protective function and improving the practicality and applicability of the protective fence.

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0031] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, this utility model provides a technical solution: it includes several fence posts 1, with a protective fence 2 fixedly installed on the opposite face of two adjacent fence posts 1. Connecting components 3 are provided on both the left and right sides of the outer surface of the protective fence 2. Each fence post 1 includes a support post 11, with a fixed base 12 fixedly connected to the bottom end of the support post 11. Connecting slots 13 are provided on both the left and right sides of the outer surface of the support post 11. Positioning components 14 are provided on both the upper and lower sides of the interior of the support post 11. Each positioning component 14 includes a cross groove 141, with two cross grooves 141 respectively located on the upper and lower sides of the interior of the fence post 1. A sliding guide post 142 is fixedly connected to the middle of the cross groove 141, and a sliding plate 143 is slidably connected to the outer surface of the sliding guide post 142. The top of the sliding plate 143 is fixedly... A clamping spring 144 is fixedly connected to the sliding guide post 142. The clamping spring 144 is set on the outer surface of the sliding guide post 142. Right-angle inserts 145 are fixedly connected to both the left and right sides of the sliding plate 143. Insertion posts 33 are slidably inserted into the inner surface of the connecting slot 13. The insertion posts 33 have a vertically penetrating positioning slot 34 inside. The bottom end of the right-angle insert 145 penetrates into the interior of the connecting slot 13 and is slidably connected to the inner surface of the positioning slot 34. A fixing seat 12 is fixedly connected to the bottom end of the support post 11. The fixing seat 12 is fixed to the ground by bolts. Connecting posts 146 are fixedly connected to both the front and rear sides of the sliding plate 143. The connecting posts 146 penetrate into the outer surface of the support post 11 and are fixedly connected to a control slider 147. The control slider 147 is slidably connected to the outer surface of the support post 11.
[0032] The overall effect of Embodiment 1 is as follows: it realizes convenient connection and stable fixation between the fence post 1 and the protective fence 2. By firmly fixing the fixing seat 12 at the bottom of the support post 11 to the ground with bolts, the stable support of the fence post 1 is ensured. When installing the protective fence 2, the plug-in post 33 on the connecting component 3 is aligned and inserted into the connecting slot 13 on the outer surface of the support post 11. At this time, the top spring 144 is in a compressed state, generating a downward elastic force to push the sliding plate 143, thereby driving the right-angle plug-in post 145 to move downward and automatically slide into the positioning slot 34 of the plug-in post 33, completing the precise positioning and firm fixation. When the protective fence 2 needs to be disassembled later, the operator only needs to push the control slider 147. The control slider 147 drives the sliding plate 143 to move upward through the connecting post 146, so that the right-angle plug-in post 145 is disengaged from the positioning slot 34, and the plug-in post 33 can be easily pulled out from the connecting slot 13, realizing the rapid separation of the protective fence 2 and the fence post 1, which greatly improves the efficiency of fence installation and maintenance.
[0033] Example 2: As Figure 4 , Figure 5 and Figure 6As shown, this utility model provides a technical solution: the protective fence 2 includes an annular support rod 21, and a plurality of isolation rods 22 are fixedly connected to the inner surface of the annular support rod 21. Two annular slots 23 are opened on both the left and right sides of the outer surface of the isolation rods 22. A plurality of positioning slots 24 are arranged in annular array on the inner surface of the annular slots 23. The connecting component 3 includes an arc-shaped clamping plate 31. The outer surface of the arc-shaped clamping plate 31 is fixedly connected to the end of the insertion post 33 away from the connecting slot 13. A threaded hole 32 is opened on both the front and rear sides of the arc-shaped clamping plate 31. The inner surface of the arc-shaped clamping plate 31 is rotatably connected to one side of the inner surface of the annular slots 23. An arc-shaped clamping plate 35 is provided on the side of the arc-shaped clamping plate 31 away from the insertion post 33. The inner surface of the arc-shaped clamping plate 35... A positioning plate 36 is rotatably connected and fixedly connected to the other side of the inner surface of the annular groove 23. The positioning plate 36 is slidably engaged in the inside of the positioning groove 24. A knob 37 is rotatably connected to the outer surface of the arc-shaped clamp 35. A movable groove is opened inside the arc-shaped clamp 35. The end of the knob 37 near the arc-shaped clamp 35 passes through the inside of the movable groove and is fixedly connected to the drive wheel 38. The front and rear sides of the outer surface of the drive wheel 38 are meshed with driven wheels 39. The two driven wheels 39 are movably connected to the front and rear sides of the inside of the movable groove respectively. A transmission screw 310 is fixedly connected to the side of the driven wheel 39 near the arc-shaped clamp 31. The transmission screw 310 passes through the side of the arc-shaped clamp 35 near the arc-shaped clamp 31 and is threadedly connected to the inner surface of the threaded hole 32.
[0034] The overall effect of Embodiment 2 is as follows: it gives the protective fence 2 the function of flexibly adjusting the angle to adapt to diverse water conservancy engineering terrain. When it is necessary to adjust the angle of the protective fence 2, the knob 37 is turned, and the knob 37 drives the driving wheel 38 to rotate. Since the driving wheel 38 meshes with the driven wheels 39 on the front and rear sides, the rotation of the driving wheel 38 causes the driven wheels 39 to rotate synchronously. The rotation of the driven wheels 39 drives the transmission screw 310 fixedly connected to one side to move in the threaded hole 32 of the arc-shaped clamp 31, thereby adjusting the angle. The distance between the arc-shaped clamp 31 and the arc-shaped clamp 35 allows the positioning plate 36 to disengage from the positioning slot 24. At this time, the protective fence 2 can freely rotate around the rotation connection point between the annular slot 23 and the arc-shaped clamp 31 and the arc-shaped clamp 35. After rotating to an angle suitable for the terrain of the water conservancy project site, the knob 37 is rotated in the opposite direction to make the positioning plate 36 re-engage into the corresponding positioning slot 24, locking the protective fence 2 at a new angle, ensuring that the protective fence can fit tightly into the complex terrain and fully exert its protective function.
[0035] The working principle of the entire device is as follows: During the installation phase, the fence post 1 is first fixed to the ground at a predetermined position using bolts via the fixing seat 12 at the bottom of the support post 11. Then, the insertion posts 33 of the connecting components 3 on both sides of the protective fence 2 are aligned with the connecting slots 13 on the outer surface of the support post 11 and inserted. At this time, the tightening spring 144 in the positioning component 14 pushes the sliding plate 143, thereby causing the right-angle insertion posts 145 on both sides of the sliding plate 143 to move downwards until the right-angle insertion posts 145 slide into the positioning slots 34 inside the insertion posts 33, completing the quick installation and stable connection between the protective fence 2 and the fence post 1. When it is necessary to disassemble the fence, the operator controls the slider 147 to push the connecting post 146, thereby causing the sliding plate 143 to overcome the elastic force of the tightening spring 144 and move upwards, causing the right-angle insertion posts 145 to disengage from the positioning slots 34. Then, the insertion posts 33 can be easily pulled out, achieving the separation of the protective fence 2 and the fence post 1. For adjusting the angle of the protective fence 2, the operator turns... The knob 37 rotates, causing the drive wheel 38, fixed at one end, to rotate within the movable groove of the second arc-shaped clamp 35. The rotation of the drive wheel 38, through meshing, drives the driven wheels 39 on both sides to rotate synchronously. When the driven wheels 39 rotate, the transmission screw 310, fixedly connected to the side closest to the first arc-shaped clamp 31, rotates accordingly and moves within the threaded hole 32 of the first arc-shaped clamp 31. This changes the distance between the first arc-shaped clamp 31 and the second arc-shaped clamp 35, causing the positioning clip on the second arc-shaped clamp 35 to... Plate 36 disengages from the positioning slot 24 within the annular slot 23 of the isolation rod 22. At this point, the protective fence 2 can rotate around the rotation connection point between the annular slot 23 and the first arc-shaped clamp 31 and the second arc-shaped clamp 35. After rotating to an angle that adapts to the terrain of the water conservancy project site, the knob 37 is rotated in the opposite direction again, and the transmission screw 310 moves in the opposite direction, so that the distance between the first arc-shaped clamp 31 and the second arc-shaped clamp 35 is restored, and the positioning plate 36 is re-engaged into the corresponding positioning slot 24, thus completing the adjustment and fixation of the angle of the protective fence 2.
[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
