Description

Technical Field

[0001] This utility model relates to the field of flood control technology for dams, and in particular to a flood control rubber dam with a filling and draining pipe structure. Background Technology

[0002] The development of flood control technology is an inevitable choice to cope with global climate change, rapid urbanization and increased disaster risks. Short-term heavy rainfall, typhoons and other extreme events occur frequently. The rapid development of urbanization has led to an increase in the area of ​​hardened surfaces. Large areas of impermeable ground have caused a surge in rainwater runoff, drainage systems to operate under overload, and underground spaces to expand. The entrances and exits of facilities such as subways and underground commercial areas are low-lying and difficult to evacuate, which can easily cause casualties and major property losses in floods. In order to protect the safety of life and property, flood control methods are also moving from passive emergency response to proactive prevention and control.

[0003] Traditional flood control methods are mainly divided into engineering flood control measures and structural waterproofing technology. Engineering flood control measures mainly include dike construction, river dredging, and flood diversion projects. Structural waterproofing technology is mainly divided into basic waterproofing construction and water-blocking facility layout. Water-blocking facility layout mainly includes sandbag wall water-blocking facilities that use woven bags filled with sand to build temporary retaining walls and baffle water-blocking facilities that install detachable baffles at the locations where water needs to be blocked.

[0004] Sandbag walls require manual construction, which is labor-intensive, slow to respond, and can easily delay flood control. Steel baffles are unstable due to the lateral force of the water flow when subjected to flood impact, causing the baffles to tilt or even collapse. They have insufficient impact resistance, rigid structures, and low adaptability. They require on-site manual splicing and adjustment during installation, which is time-consuming. Utility Model Content

[0005] To address the problem of slow installation and inability to quickly deploy existing flood control devices, this utility model provides a flood control rubber dam with a filling and draining pipe structure.

[0006] This utility model provides a flood control rubber dam with a filling and draining pipe structure, adopting the following technical solution:

[0007] A flood control rubber dam with an inflation and deflation pipe structure includes an airbag, an inflation pipe, and an anchoring device installed at the water-retaining outlet. The inflation pipe is installed on the airbag and connected to an external air source to inflate the airbag. The anchoring device connects the airbag to a fixed surface.

[0008] By adopting the above technical solution, the anchoring device is installed on the airbag. A suitable installation position is selected on the fixed surface, and the airbag is fixed to the riverbed or ground by the anchoring device to ensure its stability under the impact of flood. When flood control is required, air is inflated into the airbag through the inflation tube, causing the airbag to expand and form a water-blocking dam to block the flood outlet. The operation is convenient and flood control deployment can be completed in a short time. After the flood recedes, the airbag is deflated through the inflation tube and returns to its original shape.

[0009] Optionally, it also includes a U-shaped groove, which is formed on the fixed surface where the dam needs to be installed, and the airbag, the inflation tube and the anchoring device are installed in the U-shaped groove.

[0010] By adopting the above technical solution, the airbag is installed in the U-shaped channel. The U-shaped channel guides the water flow to both sides, reducing the water flow's scouring of the airbag and improving the dam's impact resistance. At the same time, the airbag can be pre-embedded in the U-shaped channel, which can improve the deployment speed when flood control is needed.

[0011] Optionally, the anchoring device includes a clamping member and an anchoring bolt. One end of the clamping member has a C-shaped opening, and the C-shaped opening end of the clamping member is connected to the edge of the airbag. The anchoring bolt is installed on the end of the clamping member away from the C-shaped opening, and the clamping member is connected to the fixed surface through the anchoring bolt.

[0012] By adopting the above technical solution, the clamping component holds the edge of the airbag, and the airbag can be fixed to the fixed surface by the anchor bolts to ensure its stability under the impact of floods and improve the flood protection effect of the airbag. The clamping component and the fixed surface are detachably connected by the anchor bolts, which facilitates maintenance and replacement in the later stage.

[0013] Optionally, the clamping member has an anti-detachment block at its C-shaped opening end, the anti-detachment block being located inside the C-shaped opening of the clamping member, and the edge of the airbag being thickened, with the thickening height matching the height of the anti-detachment block.

[0014] By adopting the above technical solution, the clamping component is installed on the thickened edge of the airbag. When the airbag is impacted, the anti-detachment block can press against the thickened edge of the airbag, reducing the risk of the airbag falling off.

[0015] Optionally, the anchoring device further includes reinforcing blocks, with the reinforcing blocks arranged at intervals on both the upper and lower sides of the inner side of the C-shaped opening of the clamping member, and the reinforcing blocks on the upper and lower sides being staggered.

[0016] By adopting the above technical solution, the staggered reinforcement blocks can fix the airbag from the upper and lower sides, while increasing the stress points of the airbag, which can make the connection between the airbag and the clamping device more stable.

[0017] Optionally, two airbags are provided, which are installed overlapping each other and each has an independent inflation tube, and the two airbags can inflate simultaneously.

[0018] By adopting the above technical solution, when flood control is needed, two airbags are simultaneously inflated through inflation tubes, causing them to expand and form a water-retaining dam. The superposition of the two airbags can increase the height of the water-retaining dam, improve flood resistance, increase the expansion speed, shorten the flood control deployment time, and improve the efficiency of flood control work.

[0019] Optionally, the anchoring device further includes a reinforcing plate, which is disposed within the C-shaped opening of the clamping member. The reinforcing plate is located in the middle of the C-shaped opening, and the upper and lower surfaces are provided with spaced reinforcing blocks. The reinforcing blocks of the reinforcing plate are offset from the reinforcing blocks of the clamping member.

[0020] By adopting the above technical solution, the upper airbag is installed above the reinforcing plate and the lower airbag is installed below the reinforcing plate, so that the clamping device can fix the two airbags at the same time, and both airbags can be fixed from the top and bottom sides, which improves the impact resistance of the airbags and makes the flood control effect more stable.

[0021] Optionally, the clamping component includes an adjusting bolt, two clamping plates, and a back plate. The reinforcing plate is fixedly connected to the back plate. The height of the back plate is less than the sum of the thicknesses of the two clamping plates. The two clamping plates are respectively installed on the upper and lower sides of the reinforcing plate. The clamping plates are slidably connected to the back plate. The two clamping plates and the reinforcing plate have through holes on the side away from the C-shaped opening for installing the adjusting bolt. The hexagonal head of the adjusting bolt is embedded in the clamping plate located below. A nut is provided at the end of the adjusting bolt away from the hexagonal head. The two clamping plates and the reinforcing plate are connected by the adjusting bolt.

[0022] By adopting the above technical solution, during the installation of the clamping component, the edge of the airbag is placed in the C-shaped opening formed by the clamping plate and the reinforcing plate. The end of the adjusting bolt nut is tightened, and the two clamping plates slide relative to each other on the back plate. The relative position of the two clamping plates and the reinforcing plate is adjusted by adjusting the adjusting bolt, thereby adjusting the size of the C-shaped opening so that the clamping component clamps the airbag.

[0023] Optionally, the clamping component further includes a limiting bolt. A through hole is provided at the connection between the edge of the airbag and the clamping plate. Through holes are provided at the C-shaped opening ends of the two clamping plates and the reinforcing plate. The limiting bolt connects the airbag, the reinforcing plate, and the two clamping plates through the through holes. The hexagonal head of the limiting bolt is embedded in the clamping plate located below. A nut is provided at the end of the limiting bolt away from the hexagonal head.

[0024] By adopting the above technical solution, the limiting bolt is installed in the airbag through hole, which can limit the relative displacement between the airbag and the clamping component, fix the position of the airbag, and at the same time, the limiting bolt can work with the adjusting bolt to adjust the relative position of the clamping plate and the reinforcing plate, thereby improving the clamping effect of the clamping component on the airbag.

[0025] Optionally, the contact surface between the clamping plate and the airbag is provided with a flexible material.

[0026] By adopting the above technical solution, the friction between the airbag and the clamping plate can be increased, while protecting the surface of the airbag and reducing damage to its surface when the clamping plate fixes the airbag.

[0027] Optionally, the anchoring device further includes a waterproof strip, which is installed at the connection between the clamping plate and the anchoring bolt.

[0028] By adopting the above technical solutions, the waterproof strip reduces flood infiltration and can improve the service life of the clamping components.

[0029] Optionally, a water baffle is also included, which is rotatably connected to the U-shaped groove and located above the airbag. The expansion of the airbag causes the waterproof plate to close the water baffle.

[0030] By adopting the above technical solution, the water baffle can protect the airbag when it contracts, reducing external damage. When flood prevention is needed, the airbag inflates and lifts the water baffle. After rotating 90 degrees in the U-shaped groove, the water baffle is in a vertical position, which can effectively prevent water from leaking from the side of the airbag and improve the flood prevention effect.

[0031] In summary, this utility model has at least one of the following beneficial technical effects:

[0032] The airbags and anchoring devices are simple in design and easy to install, and can be deployed in a short time when flood prevention is required.

[0033] The airbag is made of rubber, which has good aging resistance and corrosion resistance, long service life, and low maintenance cost.

[0034] Adding a water-blocking plate creates a closed design, effectively preventing water from seeping from the side and improving flood control.

[0035] It is recyclable, environmentally friendly, requires less manpower for deployment, and has low operating costs. Attached Figure Description

Detailed Implementation

[0041] The following combination Figures 1 to 4 The present invention will be described in further detail below.

[0042] This utility model discloses a flood control rubber dam with a filling and draining pipe structure.

[0043] Reference Figure 1 A flood control rubber dam with an inflation and deflation pipe structure mainly includes: an airbag 100, an inflation pipe 200, an anchoring device 300, a U-shaped groove 400, and a water-blocking plate 500, which are installed at the water-blocking opening 600. The inflation pipe 200 is installed on the airbag 100 and is connected to an external air source. The airbag 100 is inflated through the inflation pipe 200.

[0044] Figure 1 In the initial inflated state of the airbag 100, the fully inflated state causes the baffle 500 to be completely pressed against the baffle 600.

[0045] The U-shaped channel 400 is located on the ground at the water-blocking outlet 600. The airbag 100 is fixed to the fixed surface inside the U-shaped channel 400 by the anchoring device 300. The anchoring device 300 is installed on the edge of the airbag 100 and the edge is thickened. The airbag 100 is fixed to the edge of the long side of one side of the U-shaped channel 400. The water-blocking plate 500 is a rectangular plate with the same area as the U-shaped channel 400. A pivot is provided on the long side of one side of the water-blocking plate 500. The water-blocking plate 500 is rotatably connected to the U-shaped channel 400 through the pivot. The water-blocking plate 500 is installed above the airbag 100 and can be rotated 90 degrees to make the water-blocking plate 500 perpendicular to the fixed surface, thereby achieving the water-blocking effect.

[0046] The airbag 100 is rectangular in shape and made of rubber material, possessing elasticity and sealing properties. It expands after inflation. The edge of the long side of one side of the airbag 100 is thickened to form a limiting part 110. Two airbags 100 are provided, which are installed overlapping each other and each is equipped with an independent inflation tube 200. The inflation tube 200 can be fixed to the airbag 100 by adhesive and is installed on the side of the airbag 100 away from the U-shaped groove 400. In other embodiments, the inflation tube 200 can be installed at other positions on the airbag 100. The two airbags 100 are connected by an anchoring device 300 and can inflate simultaneously. The area of ​​the U-shaped groove 400 is larger than the area of ​​the rectangular airbag 100. The airbag 100 is placed in the U-shaped groove 400. After the airbag 100 is inflated, it forms a dam. The part of the U-shaped groove 400 larger than the airbag 100 forms a U-shape, which can guide the water flow to both sides, reduce the scouring of the airbag 100 by the water flow, and improve the impact resistance of the dam.

[0047] The anchoring device 300 can be anchored by pre-embedding anchor rods or drilling expansion bolts, or by drilling holes directly on the edge of the airbag 100 or fixing it with a pressure plate.

[0048] refer to Figure 2 In this embodiment, the anchoring device 300 includes a clamping member 310, a reinforcing plate 320, an anti-detachment block 330, a reinforcing block 340, an anchoring bolt 350, a waterproof strip 360, and a flexible material 370. The clamping member 310 is a rectangular clamping block with a C-shaped opening on one side. The edge of the airbag 100 with a limiting part 110 is placed inside the C-shaped opening. The end away from the C-shaped opening has a through hole, and the anchoring bolt 350 is installed in the through hole. The anchoring bolt 350 is detachably connected to the fixing surface.

[0049] The reinforcing plate 320 is fixedly installed in the C-shaped opening of the clamping member 310. Anti-detachment blocks 330 and reinforcing blocks 340 are fixedly connected to both the upper and lower surfaces of the reinforcing plate 320 and both the upper and lower surfaces inside the C-shaped opening of the clamping member 310. Anti-detachment blocks 330 are fixedly connected to the side away from the anchor bolt 350. Reinforcing blocks 340 are spaced apart between the anti-detachment blocks 330 and the anchor bolt 350. The limiting part 110 of the airbag 100, near the airbag body, abuts against the side wall of the reinforcing block 340 near the anchor bolt 350 to restrict the separation of the airbag 100 from the clamping member 310. The anti-detachment blocks 330, 340, and 350 are also fixedly connected. The height of the 0 is matched with the height of the limiting part 110 of the airbag 100. The height of the reinforcing block 340 is less than the height of the anti-detachment block 330, and the reinforcing block 340 on the reinforcing plate 320 is misaligned with the reinforcing block 340 on the clamping member 310. The flexible material 370 is fixedly connected to the contact surface between the clamping member 310, the reinforcing plate 320, the anti-detachment block 330 and the reinforcing block 340 and the airbag 100, increasing the friction between the contact surface and the surface of the airbag 100, while protecting the surface of the airbag 100. The waterproof strip 360 is installed at the connection between the anchor bolt 350 and the clamping member 310 and the fixed surface to reduce water infiltration.

[0050] The implementation principle of Embodiment 1 of this utility model is as follows: A U-shaped groove 400 is opened in the ground at the water-blocking outlet 600. Anchoring device 300 is installed on one side of the edge of airbag 100, which is thickened to form a limiting part 110. Two airbags 100 are installed overlapping each other. The limiting parts 110 of the airbags 100 are respectively connected to the C-shaped openings above and below the reinforcing plate 320. Anchoring device 300 is fixed to the fixing surface in the U-shaped groove 400 by anchoring bolts 350, thereby fixing the airbag 100 to the U-shaped groove 400. On the fixed surface within the U-shaped groove 400, the water-blocking plate 500 is installed within the U-shaped groove 400, allowing relative rotation with the U-shaped groove 400. The water-blocking plate 500 is positioned above the airbag 100, protecting the airbag 100 and reducing external damage. When flood control is needed, air is simultaneously injected into both airbags 100 through the inflation pipe 200, causing the airbags 100 to rapidly expand and form a water-blocking dam to seal the flood outlet. After expansion, the airbags 100 push up the water-blocking plate 500, which then rotates 90 degrees within the U-shaped groove 400, becoming vertical. In its straight state, the blocked waterproof opening effectively reduces water leakage from the side of the airbag 100, improving flood control. After the airbag 100 inflates, the U-shaped groove 400 guides the water flow to both sides, reducing the scouring of the airbag 100 and improving the impact resistance of the dam. When the airbag 100 is impacted by floodwater, the limiting part 110 of the airbag 100 abuts against the anti-detachment block 330, reducing the risk of the airbag 100 falling off during impact. At the same time, the reinforcing plate 320 and the staggered reinforcing block 340 can increase the strength of the airbag 100. The force-bearing area of ​​the airbag 100 is clamped from multiple directions, making the connection between the airbag 100 and the anchoring device 300 more stable and improving the impact resistance of the airbag 100. The flexible material 370 increases the friction between the airbag 100 and the clamping plate 312, while reducing the damage to the surface of the airbag 100 when the clamping plate 312 fixes the airbag 100, thus protecting the surface of the airbag 100. The waterproof strip 360 seals the gap between the anchoring bolt 350 and the fixing surface, reducing flood infiltration and extending the service life of the device.

[0051] Example 2: Reference Figure 3 and Figure 4The difference between this embodiment and Embodiment 1 is that the clamping component 310 is assembled in a split form, including a back plate 311, two clamping plates 312, adjusting bolts 380 and limiting bolts 390. Both clamping plates 312 are L-shaped, forming a C-shaped opening. The shorter portions of the two clamping plates 312 are slidably connected to the back plate 311 via sliders 313 and grooves 314. The reinforcing plate 320 is fixedly connected to the back plate 311 and located between the two clamping plates 312. The reinforcing plate 320 is parallel to the longer plates of the clamping plates 312. The height of the back plate 311 is less than the sum of the heights of the shorter plates of the two clamping plates 312. The two clamping plates 312 and the reinforcing plate 320 have through holes on the side away from the C-shaped opening for installation. An adjusting bolt 380 has its hexagonal head embedded in the lower clamping plate 312. A nut is provided at the end of the adjusting bolt 380 away from the hexagonal head. The two clamping plates 312 and the reinforcing plate 320 are connected by the adjusting bolt 380 and fixed by the nut. A limiting hole is provided at the connection between the airbag 100 limiting part 110 and the clamping plate 312. A through hole is provided at the end of the two clamping plates 312 and the reinforcing plate 320 away from the adjusting bolt 380. A limiting bolt 390 is installed in the through hole, connecting the airbag 100, the reinforcing plate 320 and the two clamping plates 312. The hexagonal head of the limiting bolt 390 is embedded in the lower clamping plate 312. A nut is provided at the end of the limiting bolt 390 away from the hexagonal head.

[0052] In other embodiments, a waterproof strip 360 may be provided on the side of the back panel 311 closest to the ground, so that the waterproof strip 360 contacts the ground, reducing the possibility of water passage.

[0053] The implementation principle of Embodiment 2 of this utility model is as follows: During the installation of the clamping component 310, the limiting parts 110 of the two airbags 100 are respectively placed in the upper and lower C-shaped openings formed by the clamping plate 312 and the reinforcing plate 320. The nut ends of the adjusting bolt 380 and the limiting bolt 390 are tightened, so that the two clamping plates 312 slide relative to each other on the back plate 311. The relative positions of the two clamping plates 312 and the reinforcing plate 320 are adjusted by adjusting the adjusting bolt 380, thereby... Adjusting the size of the C-shaped opening allows the clamping member 310 to clamp the airbag 100. The limiting bolt 390 is installed in the through hole of the airbag 100, which can limit the relative displacement between the airbag 100 and the clamping member 310, fix the position of the airbag 100, and the limiting bolt 390 can work with the adjusting bolt 380 to adjust the relative position of the clamping plate 312 and the reinforcing plate 320, improve the clamping effect of the clamping member 310 on the airbag 100, and thus improve the impact resistance of the airbag 100.

[0054] In summary, the airbag and anchoring device are simple in design and easy to install. They can be deployed in a short time when flood control is needed. The airbag is made of rubber, which has good aging and corrosion resistance, long service life, and low maintenance cost. The addition of a water baffle forms a closed design, which effectively prevents water from seeping from the side, improves the flood control effect, is recyclable, green and environmentally friendly, and has low manpower cost for deployment and low operating cost.

[0055] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
