Technical Field

[0001] The utility model relates to the field of river bank slope protection devices, in particular to a wave-shaped air bag bank slope protection device. Background Art

[0002] River bank slope protection construction is an effective measure for river management. At present, common bank slope protection measures include engineering protection measures and ecological protection measures. Among them, engineering protection measures include sediment accumulation, concrete pouring, laying of gabions, etc. Although engineering protection measures have good protection effects, they are costly and not conducive to later maintenance; ecological protection measures include wire mesh and gravel composite planting bases, civil material soil-fixing planting bases, three-dimensional vegetation nets, cement ecological planting bases, etc. Ecological protection measures can improve the ecological environment of the river and fix the bank slope soil, but the ability to resist river erosion is limited, the protection period is short, and it is very easy to be destroyed when a major flood occurs. Therefore, in order to improve the bank slope protection effect and reduce the protection cost, a wave-shaped airbag bank slope protection device is particularly needed.

[0003] Because when protecting the bank slope, most of the bank slope protection measures will have good protection effects but high costs, while other bank slope protection measures have limited resistance, high losses, and low protection effects, which may lead to inevitable losses when protecting the bank slope. Utility Model Content

[0004] The purpose of the utility model is to provide a wave-shaped airbag slope protection device to solve the problem raised in the above-mentioned background technology that when protecting the slope, most of the slope protection measures will have a good effect during protection but a high cost, while other slope protection measures have limited resistance, high loss and low protection effect, which may inevitably cause losses when protecting the slope.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a wave-shaped airbag slope protection device, comprising a pressure plate, a movable piston is installed on the lower surface of the pressure plate, an air inlet hole is opened on the lower surface of the pressure plate, a piston slide is fixedly connected to the lower surface of the pressure plate, a side surface of the piston slide is fixedly connected to the pressure plate slide, a gas storage chamber is opened on the lower surface of the pressure plate, a wave-shaped airbag is installed on one end surface of the air inlet hole, an air pipeline is fixedly connected to the outer surface of the wave-shaped airbag, a fixed plate is fixedly connected to one side surface of the air pipeline, and an anchor is fixedly connected to the upper surface of the fixed plate.

[0006] Preferably, the inner wall size of the air inlet hole matches the outer wall size of the air duct, and the piston slide rails are evenly spaced and distributed on one side surface of the pressure plate.

[0007] Preferably, the pressure plate slide rails are distributed at equal intervals on one side surface of the piston slide rail, and the piston slide rail and the pressure plate slide rail form a sliding structure.

[0008] Preferably, the wave-shaped airbags are evenly spaced on a side surface of the air duct, and the air ducts are evenly spaced on an upper surface of the fixed plate.

[0009] Preferably, the air duct and the fixing plate form a snap-fit ​​structure, and the material of the air duct is rubber.

[0010] Preferably, the fixing plate and the anchors form a snap-fit ​​structure, and the anchors are distributed at equal intervals on the upper surface of the fixing plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when the river bank protection device needs to protect the bank, first, when the water volume in the river increases and the water level rises, the pressure plate of the pressure inflation system will move down along the vertical slide rail under the action of water pressure, and push the piston to move down to squeeze the gas in the gas storage chamber, the volume of the gas storage chamber will decrease, and the excess gas will enter the air inlet pipe; when the water volume decreases and the water level drops, the squeezed gas will return to the gas storage chamber from the air inlet pipe, the water pressure and the pressure of the gas storage chamber will always be in dynamic balance, and the airbag The fixed plate and anchor nails are embedded in the bank slope, and the outer side of the airbag is in contact with the water surface. When the gas in the pressure inflation device enters the inflation pipe, it is input into the airbag through the inflation pipe. At this time, the volume of the airbag increases, and the contact area with the water surface increases, which changes the direction of the force of the water flow, reduces the energy stored in the water flow, and weakens the scouring and erosion of the river on the bank slope. When the water flow recedes, the gas in the airbag re-enters the inflation pipe and enters the gas storage chamber of the pressure inflation system along the air inlet pipe. At this time, the volume of the airbag decreases, the contact area with the water surface decreases, and the anti-scouring ability is weakened. During the entire operation process, the volume of the airbag can be automatically adjusted according to the change of the water volume in the river channel, so the anti-scouring strength of the river bank slope can also be automatically adjusted with the different water volume in the river channel. This operation mode greatly improves the protection level of the bank slope. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: a wave-shaped airbag bank slope protection device, including a pressure plate 1, a movable piston 2 is installed on the lower surface of the pressure plate 1, an air inlet hole 3 is opened on the lower surface of the pressure plate 1, a piston slide rail 4 is fixedly connected to the lower surface of the pressure plate 1, a pressure plate slide rail 5 is fixedly connected to one side surface of the piston slide rail 4, a gas storage chamber 6 is opened on the lower surface of the pressure plate 1, a wave-shaped airbag 7 is installed on one end surface of the air inlet hole 3, an air pipeline 8 is fixedly connected to the outer surface of the wave-shaped airbag 7, a fixed plate 10 is fixedly connected to one side surface of the air pipeline 8, an anchor 11 is fixedly connected to the upper surface of the fixed plate 10, through the arrangement of the pressure plate 1, the movable piston 2, the air inlet hole 3, the piston slide rail 4, the pressure plate slide rail 5, the gas storage chamber 6, the wave-shaped airbag 7, the air pipeline 8, the fixed plate 10, and the anchor 11, when in use, when it is necessary to protect the bank, first when the water volume in the river increases and the water level rises, the pressure is inflated The pressure plate 1 of the system will move down along the vertical slide rail under the action of water pressure, and push the piston down to squeeze the gas in the gas storage chamber 6. The volume of the gas storage chamber 6 will decrease, and the excess gas will enter the air inlet pipe. When the water volume decreases and the water level drops, the squeezed gas will return to the gas storage chamber 6 from the air inlet pipe. The water pressure and the pressure of the gas storage chamber 6 are always in dynamic balance. The airbag is embedded in the bank slope by the fixed plate 10 and the anchor 11, and the outer side of the airbag is in contact with the water surface. When the gas in the pressure inflation device enters the inflation pipe, it is input into the airbag through the inflation pipe. At this time, the volume of the airbag increases, and the contact area with the water surface increases, which changes the direction of the force of the water flow, reduces the energy stored in the water flow, and weakens the scouring and erosion effect of the river on the bank slope. When the water flow recedes, the gas in the airbag re-enters the inflation pipe and enters the gas storage chamber 6 of the pressure inflation system along the air inlet pipe. At this time, the volume of the airbag decreases, the contact area with the water surface decreases, and the anti-scouring ability is weakened. During the entire operation process, the volume of the airbag can be automatically adjusted according to the change of the water volume in the river channel, so the anti-scouring strength of the river bank slope 9 can also be automatically adjusted with the different water volumes in the river channel. This operation mode greatly improves the protection level of the bank slope.

[0018] Furthermore, the inner wall size of the air inlet hole 3 is consistent with the outer wall size of the air pipe 8, and the piston slide rails 4 are evenly distributed on the one side surface of the pressure plate 1. Through the setting of the air inlet hole 3, the wave-shaped airbag 7 can be better inflated.

[0019] Furthermore, the pressure plate slide rails 5 are evenly spaced on one side surface of the piston slide rail 4 , and the piston slide rail 4 and the pressure plate slide rail 5 form a sliding structure. By setting the pressure plate slide rail 5 , the pressure plate 1 can be slid better.

[0020] Furthermore, the wave-shaped airbags 7 are evenly spaced on one side surface of the air duct 8, and the air duct 8 is evenly spaced on the upper surface of the fixed plate 10. By setting the wave-shaped airbags 7, the scouring of the bank slope by the water flow can be better reduced.

[0021] Furthermore, the air duct 8 and the fixing plate 10 form a snap-fit ​​structure. The material of the air duct 8 is rubber. By setting the fixing plate 10 , the wave-shaped airbag 7 and the air duct 8 can be better fixed on the fixing plate 10 .

[0022] Furthermore, the fixing plate 10 and the anchors 11 form a snap-fit ​​structure, and the anchors 11 are evenly spaced on the upper surface of the fixing plate 10 . By providing the anchors 11 , the fixing plate 10 can be better and more stably fixed.

[0023] Working principle: First, when the bank needs to be protected, when the water volume in the river increases and the water level rises, the pressure plate 1 of the pressure inflation system will move down along the vertical slide rail under the action of water pressure, and push the piston down to squeeze the gas in the gas storage chamber 6. The volume of the gas storage chamber 6 decreases, and the excess gas enters the air inlet pipe. When the water volume decreases and the water level drops, the squeezed gas returns to the gas storage chamber 6 from the air inlet pipe. The water pressure and the pressure of the gas storage chamber 6 are always in dynamic balance. The air bag is embedded by the fixing plate 10 and the anchor 11. In the bank slope, the outer side of the airbag contacts the water surface. When the gas in the pressure inflation device enters the inflation pipe, it is input into the airbag through the inflation pipe. At this time, the volume of the airbag increases, and the contact area with the water surface increases, which changes the direction of the force of the water flow, reduces the energy stored in the water flow, and weakens the scouring and erosion of the river on the bank slope. When the water flow recedes, the gas in the airbag re-enters the inflation pipe and enters the pressure inflation system gas storage chamber 6 along the air inlet pipe. At this time, the volume of the airbag decreases, the contact area with the water surface decreases, and the anti-scouring ability is weakened. During the entire operation process, the volume of the airbag can be automatically adjusted according to the change of the water volume in the river channel, so the anti-scouring strength of the river bank slope 9 can also be automatically adjusted according to the different water volume in the river channel. This operation mode greatly improves the protection level of the bank slope.
