Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, specifically a safety protection structure for water conservancy construction. 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. They are also called water engineering projects. The construction of water conservancy projects can control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production for water resources. In the construction of water conservancy projects, some protective devices are needed to prevent unauthorized personnel from accidentally entering the construction site and causing unnecessary safety hazards.

[0003] A search revealed a safety protection structure for water conservancy construction with application number 202010837302.X. This safety protection structure includes a protective net, a connecting frame, and internal hexagonal bolts. The protective net is fixedly connected to the frame. This safety protection structure is relatively flexible to transport before being put into use, and can be quickly deployed and stably placed on the ground after being put into use. It is simple to operate and has good stability. However, when transporting and transferring the device, the connecting net and the fixed frame need to be separated to reduce the size of the device. It needs to be moved multiple times before it can be put into the vehicle for transfer, which is cumbersome and increases the labor intensity of workers. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a safety protection structure for water conservancy construction, so as to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection structure for water conservancy construction, comprising a mounting base, a fixed frame connected to the top of the mounting base, a rotating shaft connected to the upper part of the fixed frame, a baffle connected to the outer surface of the rotating shaft, a folding frame connected inside the baffle, a counterweight plate connected to the bottom of the folding frame, a limit rod connected to the outer surface of the counterweight plate, a limit groove provided on the inner wall of the baffle, a sliding rod and a limit plate connected inside the limit groove, and a spring and a lever connected to the outer surface of the sliding rod.

[0006] Furthermore, the fixing frame is in the shape of an "n", and the baffle is rotatably connected to the fixing frame via a rotating shaft.

[0007] By adopting the above technical solution, after the mounting frame is installed, the fixing bolts are loosened, and the baffle is rotated by the rotating shaft, so that the baffle is lifted and one side of the baffle enters into another mounting frame. The baffle is fixed by inserting the fixing bolts into the first fixing hole and the second fixing hole above the outer surface of the other set of mounting frames, thus surrounding the construction site and preventing irrelevant personnel from entering the construction site.

[0008] Furthermore, the baffle has a receiving cavity inside, and the folding frame is slidably connected to the receiving cavity through a counterweight plate.

[0009] By adopting the above technical solution, after the baffle is fixed, the lever is moved to move the slide bar, so that the slide bar stops limiting the limit rod. Under the weight of the counterweight frame itself, the folding frame leaves the receiving cavity and extends downward to cover the area below the baffle and expand the coverage area.

[0010] Furthermore, the counterweight plate has an "I" shaped cross-section and is slidably connected to the fixing frame.

[0011] By adopting the above technical solution, the outer surfaces of the counterweight plate are always in contact with the inside of the fixed frame. The counterweight plate slides inside the fixed frame, which prevents the counterweight plate from shifting when it drives the folding frame to unfold or retract, thus affecting the practicality of the device.

[0012] Furthermore, the slide rod is slidably connected to the limiting groove, and one end of the slide rod is inclined.

[0013] By adopting the above technical solution, when disassembling the device, the worker lifts the counterweight plate. When the counterweight plate enters the receiving cavity, the limiting rod squeezes the sliding rod, causing the sliding rod to slide in the limiting groove and squeeze the spring. The limiting plate limits the spring and the sliding rod, preventing the spring from popping out of the limiting groove. When the limiting rod is above the sliding rod, the sliding rod returns to its original position under the action of the spring force, thereby locking the counterweight plate and the folding frame in the receiving cavity, reducing the longitudinal volume of the device. The inclined setting facilitates the limiting rod to squeeze the sliding rod.

[0014] Furthermore, a first fixing hole is provided both below and above the outer surface of the fixing frame, and a second fixing hole is provided on one side of the outer surface of the baffle, with the second fixing hole corresponding to the first fixing hole.

[0015] By adopting the above technical solution, when the baffle is not yet lifted, the baffle is locked by inserting the fixing bolts into the fixing holes and the second fixing holes below the outer surface of the fixing frame, so as to prevent the baffle from opening on its own during transportation and affecting the handling. When the baffle is lifted, the baffle is fixed by inserting the fixing bolts into the first fixing holes and the second fixing holes above the outer surface of another set of mounting frames, so as to prevent the baffle from sagging under its own weight and affecting the shielding effect on the construction site.

[0016] Furthermore, fixing bolts are connected to the first fixing hole and the second fixing hole, and the fixing bolts are detachably connected to the first fixing hole and the second fixing hole respectively.

[0017] By adopting the above technical solution, the baffle is fixed in different positions by inserting the fixing bolts into the first fixing holes at different positions. When the staff puts the baffle into the fixing frame, the baffle can be prevented from rotating on its own. At the same time, the overall volume of the protective structure is reduced to facilitate transportation. When the baffle is lifted, it can be prevented from moving down under its own weight.

[0018] Furthermore, the top of the mounting base is provided with four sets of fastening bolts.

[0019] By adopting the above technical solution, four sets of fastening bolts are located on both sides of the top of the mounting base. The bottom of the fastening bolts is tapered, which makes it easy to insert them into the soil. During installation, the workers insert the fastening bolts into the threaded holes and into the soil to fix the mounting base.

[0020] Furthermore, a sliding groove is provided below the outer surface of the baffle, and the paddle is slidably connected to the sliding groove.

[0021] By adopting the above technical solution, one side of the lever passes through the slide groove, and the width of the lever is adapted to the width of the slide groove. By moving the lever in the slide groove, it cooperates with the limiting plate to compress the spring, thereby driving the slide rod into the limiting groove, releasing the restriction on the limiting rod, and allowing the folding frame to slide out of the receiving cavity. Under the action of the counterweight plate, it blocks the area below the baffle.

[0022] Furthermore, the outer surface of the baffle is provided with reflective strips.

[0023] By adopting the above technical solution, the light is reflected back along the original path through reflective strips, which enhances the visibility of the device, attracts people's visual attention, and avoids people accidentally entering the construction site due to poor visibility at night.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by setting up a baffle, a counterweight plate, a folding frame, and a receiving cavity, allows for the following steps: Before construction, the fixed frame is installed, and the baffle is rotated by a pivot, causing it to lift and one side to enter another mounting frame. The baffle is then fixed by inserting fixing bolts into the first and second fixing holes on the outer surface of the other mounting frame, thus enclosing the construction site and preventing unauthorized personnel from entering. After the baffle is fixed, a lever is moved to move the sliding rod, causing it to stop limiting the limit rod. Under the weight of the counterweight frame, the folding frame moves away from the receiving cavity and downwards, covering the area below the baffle and expanding the coverage area. After construction, when disassembling the device, workers lift the counterweight plate to retract the folding frame. By retracting the folding frame and counterweight plate into the receiving cavity and rotating the baffle to enter the fixed frame, the overall size of the device is reduced, allowing it to be placed in a vehicle for transfer without disassembling the components, reducing manual pulling effort and facilitating quick installation in the future.

[0026] 2. This utility model, by setting a limiting groove, a sliding rod, a spring, and a lever, allows the worker to lift the counterweight plate when disassembling the device. When the counterweight plate enters the receiving cavity, the limiting rod presses against the sliding rod, causing the sliding rod to slide within the limiting groove and press against the spring. The limiting plate limits the spring and the sliding rod, preventing the spring from popping out of the limiting groove. When the limiting rod is above the sliding rod, the spring force causes the sliding rod to return to its original position, thereby locking the counterweight plate and the folding frame within the receiving cavity, further reducing the size of the device.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1: A safety protection structure for water conservancy construction, such as Figures 1-7 As shown, the device includes a mounting base 1, a fixed frame 2 connected to the top of the mounting base 1, a rotating shaft 3 connected to the upper part of the fixed frame 2, a baffle 5 connected to the outer surface of the rotating shaft 3, a folding frame 6 connected inside the baffle 5, and a counterweight plate 7 connected to the bottom of the folding frame 6. The counterweight plate 7 has an "I" shaped cross-section and is slidably connected to the fixed frame 2. The two sides of the outer surface of the counterweight plate 7 are always in contact with the inside of the fixed frame 2. By sliding the counterweight plate 7 inside the fixed frame 2, it is possible to prevent the counterweight plate 7 from shifting when it drives the folding frame 6 to unfold or retract, thereby affecting the practicality of the device. A limit rod 8 is connected to the outer surface of the counterweight plate 7, and a limit groove 9 is provided on the inner wall of the baffle 5. A sliding rod 10 and a limit plate 13 are connected inside the limit groove 9. A spring 12 and a lever 11 are connected to the outer surface of the sliding rod 10.

[0038] See Figure 1 , Figure 2 , Figure 3 and Figure 6 In the above embodiment, the fixing frame 2 is in the shape of an "n". The baffle 5 is rotatably connected to the fixing frame 2 through the rotating shaft 3. After the mounting frame is installed, the fixing bolt 16 is loosened, and the baffle 5 is rotated through the rotating shaft 3, so that the baffle 5 is lifted and one side of the baffle 5 enters another mounting frame. The baffle 5 is fixed by inserting the fixing bolt 16 into the first fixing hole 14 and the second fixing hole 15 above the outer surface of the other set of mounting frames, thus enclosing the construction site and preventing irrelevant personnel from entering the construction site.

[0039] See Figure 5 In the above embodiment, the baffle 5 is provided with a receiving cavity 19. The folding frame 6 is slidably connected to the receiving cavity 19 through the counterweight plate 7. After the baffle 5 is fixed, the lever 11 is moved to drive the slide rod 10 to move, so that the slide rod 10 stops limiting the limit rod 8. Under the drive of the counterweight frame itself, the folding frame 6 leaves the receiving cavity 19 and extends downward to cover the area below the baffle 5 and expand the coverage area.

[0040] See Figure 4 and Figure 7 In the above embodiment, the slide rod 10 is slidably connected to the limiting groove 9, and one end of the slide rod 10 is inclined. When disassembling the device, the operator lifts the counterweight plate 7. When the counterweight plate 7 enters the receiving cavity 19, the limiting rod 8 squeezes the slide rod 10, causing the slide rod 10 to slide in the limiting groove 9 and squeeze the spring 12. The limiting plate 13 limits the spring 12 and the slide rod 10 to prevent the spring 12 from popping out of the limiting groove 9. When the limiting rod 8 is above the slide rod 10, the slide rod 10 returns to its original position under the elastic force of the spring 12, thereby locking the counterweight plate 7 and the folding frame 6 in the receiving cavity 19, reducing the longitudinal volume of the device. The inclined setting facilitates the limiting rod 8 to squeeze the slide rod 10.

[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 In the above embodiment, a first fixing hole 14 is provided on both the lower and upper outer surfaces of the fixing frame 2, and a second fixing hole 15 is provided on one side of the outer surface of the baffle 5, with the second fixing hole 15 corresponding to the first fixing hole 14. When the baffle 5 is not yet lifted, the baffle 5 is locked by inserting the fixing bolt 16 into the fixing hole 14 on the lower outer surface of the fixing frame 2 and the second fixing hole 15, so as to prevent the baffle 5 from opening on its own during transportation and affecting the handling. When the baffle 5 is lifted, the baffle 5 is fixed by inserting the fixing bolt 16 into the first fixing hole 14 and the second fixing hole 15 on the upper outer surface of another set of mounting brackets, so as to prevent the baffle 5 from drooping under its own weight and affecting the shielding effect on the construction site.

[0042] See Figure 1 and Figure 3 In the above embodiment, fixing bolts 16 are connected to the first fixing hole 14 and the second fixing hole 15, and the fixing bolts 16 are detachably connected to the first fixing hole 14 and the second fixing hole 15 respectively. By inserting the fixing bolts 16 into the first fixing hole 14 at different positions, the baffle 5 is fixed at different positions. When the staff puts the baffle 5 into the fixing frame 2, the baffle 5 can be prevented from rotating on its own, and the overall volume of the protective structure is reduced to facilitate transportation. When the baffle 5 is lifted, the baffle 5 can be prevented from moving down under its own weight.

[0043] See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 In the above embodiment, the top of the mounting base 1 is provided with four sets of fastening bolts 18. The four sets of fastening bolts 18 are located on both sides of the top of the mounting base 1. The bottom of the fastening bolts 18 is tapered, which makes it easy to insert into the soil. During installation, the workers insert the fastening bolts 18 into the threaded holes and into the soil to fix the mounting base 1.

[0044] See Figure 4 In the above embodiment, a groove 4 is provided below the outer surface of the baffle 5, and the lever 11 is slidably connected to the groove 4. One side of the lever 11 passes through the groove 4, and the width of the lever 11 is adapted to the width of the groove 4. By moving the lever 11 in the groove 4, it cooperates with the limiting plate 13 to squeeze the spring 12, thereby driving the sliding rod 10 into the limiting groove 9, releasing the restriction on the limiting rod 8, so that the folding frame 6 slides out from the receiving cavity 19, and under the action of the counterweight plate 7, it blocks the bottom of the baffle 5.

[0045] Example 2: To improve the device's warning effect at night, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 1 , Figure 2 and Figure 3 The outer surface of the baffle 5 is provided with reflective strips 17, which reflect light back along the original path to enhance the visibility of the device, attract people's visual attention, and prevent people from accidentally entering the construction site due to poor visibility at night.

[0046] The implementation principle of this utility model is as follows: After the mounting base 1 and the fixing frame 2 are installed at a set distance, the fixing bolt 16 is loosened, and the baffle 5 is rotated upward by the rotating shaft 3. By passing the fixing bolt 16 through the second fixing hole 15 and the first fixing hole 14 above the outer surface of the other fixing frame 2, the baffle 5 is fixed. At this time, the lever 11 is moved, so that the sliding rod 10 enters the limiting groove 9, and the limiting rod 8 disengages from the baffle 5. Under the action of the counterweight plate 7's own weight, the counterweight plate 7 drives the folding frame 6 to leave the receiving cavity 19 and extend downward, covering the area below the baffle 5, thereby completing the installation. When the safety structure is disassembled at the end of the project, the counterweight plate 7 is lifted upward, so that... The folding frame 6 moves upward and retracts. When the counterweight plate 7 enters the receiving cavity 19, the limiting rod 8 presses against the sliding rod 10 and compresses the spring 12. When the limiting rod 8 is above the sliding rod 10, the sliding rod 10 returns to its original position under the elastic force of the spring 12, thereby locking the counterweight plate 7 and the folding frame 6 in the receiving cavity 19. At this time, the fixing bolt 16 is pulled out, the baffle 5 is rotated to enter the fixed frame 2, and then the fixing bolt 16 is inserted into the first fixing hole 14 below the outer surface of the fixed frame 2 and the second fixing hole 15 on the outer side of the baffle 5 to fix the baffle 5. Then the fastening bolt 18 is loosened to remove the mounting base 1, and finally it is loaded onto the vehicle for transfer.
