TECHNICAL FIELD
[0001] The present application relates to the technical field of gate, in particular to a bidirectional water-stopping gate. BACKGROUND
[0002] At present, in the field of water conservancy, water-stopping gates play a crucial role, and they are the key equipment for controlling the flow direction and flow rate of water. These gates are widely used in various fields, including but not limited to urban water supply and drainage systems, farmland irrigation and drainage systems, channel water diversion projects, flood control facilities, and seawater aquaculture. These application scenarios have high requirements for the functionality and reliability of water-stopping gates.
[0003] In the prior art, in some water conservancy application environments, when the water on both sides surges after being blocked by the gate, it will push the gate to sway along the direction of the water flow or the opposite direction of the water flow, extruding the water-stopping seal, and the sway will cause a gap between the gate and the water-stopping seal, allowing water to flow through the gap and pass through the gate, thereby reducing the water-stopping effect of the gate. CONTENT OF THE UTILITY MODEL
[0004] In order to improve the water-stopping effect of the gate, the present application provides a bidirectional water-stopping gate.
[0005] The bidirectional water-stopping gate provided by the present application adopts the following technical solution:
[0006] A bidirectional water-stopping gate, comprising:
[0007] A gate frame is arranged on a building main body and forms a sliding space in the shape of a frame;
[0008] A sliding rail is arranged in the sliding space formed by the gate frame;
[0009] A door body slides in the sliding space through the sliding rail and can slide to one side of the gate frame to stop the flow of water;
[0010] A driving mechanism is arranged on the gate frame to drive the door body to slide;
[0011] A water-stopping frame is arranged on the gate frame and is provided with two groups located on both sides of the door body;
[0012] A water-stopping seal is arranged on the water-stopping frame and abuts against the door body, and a first inflation cavity is formed in the interior, and the first inflation cavities of the two water-stopping seals are communicated.
[0013] By adopting the technical scheme, when the door body is not used, the door body is located in the sliding space of the gate frame and is usually in an open or intermediate position to allow water flow; when water stopping is needed, the door body is driven by a driving mechanism (such as a motor, a hydraulic cylinder or the like) to slide along the sliding rail to one side of the gate frame, thereby blocking the water flow; with the movement of the door body, the door body gradually contacts the water stopping seals on the water stopping frame; since the first air chambers are arranged in the water stopping seals and the first air chambers of the two water stopping seals are communicated, when the water flow surges, the door body is pushed to move, the door body shakes to extrude the first air chamber on one side, the air chamber on the opposite side expands, in the extruding process, the air interacts with each other to slow down the shaking of the door body, and the water stopping seal on the opposite side always abuts against the door body to form an effective water stopping barrier. This design not only improves the water stopping effect, but also enhances the sealing and stability between the door body and the water stopping seal; since the water stopping frame is arranged in two groups and is located on the two sides of the door body, the bidirectional water stopping gate can realize bidirectional water stopping of the water flow. That is, no matter which direction the water flow flows to the gate, the water flow can be effectively blocked by adjusting the position of the door body, thereby improving the water stopping effect.
[0014] Optionally, the gate frame is further provided with a bottom water stopping frame, the bottom water stopping frame is formed with a containing space, the containing space is provided with a bottom water stopping strip, the bottom water stopping strip is formed with a second air chamber, the second air chamber is communicated with the two first air chambers, and the door body partially enters the containing space when the door body extrudes the bottom water stopping strip.
[0015] By adopting the technical scheme, in the falling process of the door body, the door body extrudes the bottom water stopping strip, the air in the second air chamber enters the first air chamber, the first air chamber expands, the abutting force on the two sides of the door body increases, the sealing effect is enhanced, the friction is relatively small in the falling process, the friction on the water stopping seal is reduced, the service life is prolonged, and the sealing effect is maintained.
[0016] Optionally, a clamping groove is formed in the side wall of the door body close to the bottom water stopping frame, and an embedded seal is arranged on the bottom water stopping strip and located in the clamping groove.
[0017] By adopting the technical scheme, in the falling process of the door body, the embedded seal is clamped into the clamping groove, and the embedded seal is arranged to further enhance the sealing of the bottom water and improve the sealing effect.
[0018] Optionally, a side sealing groove is formed in the door body, a side sealing seal is arranged in the side sealing groove, the side sealing seal is arranged in two groups and located in the clamping groove, and the side sealing seal can abut against the side wall of the embedded seal.
[0019] By adopting the technical scheme, since the pressure of the bottom water is relatively large, after the door body part is embedded into the bottom water stop frame, the side seal abuts against and is embedded for sealing, thereby increasing the sealing effect on the bottom water.
[0020] Optionally, a drainage groove is formed on the side wall of the bottom water stop strip away from the bottom water stop strip, the drainage groove is in communication with the side seal groove, and an expansion bag is arranged in the drainage groove, a third inflation cavity is formed in the expansion bag, and the expansion bag is pressed against the side seal as the water pressure in the drainage groove rises.
[0021] By adopting the technical scheme, when the door body falls, water is gathered at the drainage groove, the gathered water cannot flow, the pressure is increased, the water is compressed, the water presses against the expansion bag, the gas in the expansion bag enters the fourth inflation cavity, the abutting force of the side seal against the embedded sealing is increased, the sealing effect is increased, and the water pressure in the drainage groove is greater than the external water pressure, the entry of the external water is reduced, and the sealing effect is further improved.
[0022] Optionally, the door body is provided with a pressing assembly, and the pressing assembly comprises:
[0023] a pressing plate that is slid in the side seal groove, abuts against the side seal, and pushes the side seal to be close to the clamping groove;
[0024] a pressing rod that is slid on the door body, is connected with the pressing plate, and abuts against the inner wall of the bottom water stop frame.
[0025] By adopting the technical scheme, when the door body falls, the inner wall of the bottom water stop frame abuts against the pressing rod, the pressing rod drives the pressing plate to slide, the pressing plate presses against the side seal, the side seal is close to the embedded sealing, and the sealing effect is increased.
[0026] Optionally, the door body is provided with a lateral support wheel, the gate frame is provided with an auxiliary plate, the auxiliary plate abuts against the lateral support wheel, and the auxiliary plate is used for reducing the swing amplitude of the door body.
[0027] By adopting the technical scheme, the lateral support wheel is arranged, the excessive swing of the door body is reduced, the excessive pressing damage to the water stop sealing is reduced, and the sealing effect is maintained.
[0028] In summary, the application has at least one of the following beneficial technical effects:
[0029] 1. Since the water-stop seal has a first air chamber inside, and the first air chambers of the two water-stop seals are connected, when the water flows, it pushes the door to move. The door shakes and squeezes the first air chamber on one side, causing the air chamber on the other side to expand. At the same time, during the squeezing process, the interaction of air slows down the shaking of the door and ensures that the water-stop seal on the other side is always pressed against the door, forming an effective water-stop barrier.
[0030] 2. As the door descends, water accumulates in the drainage groove. The accumulated water cannot flow, which increases the pressure. As the water is compressed, it squeezes the expansion bladder, causing the gas inside the expansion bladder to enter the fourth inflation chamber. This strengthens the sealing force of the side seal against the embedded seal, increasing the sealing effect. Furthermore, the water pressure in the drainage groove is greater than the external water pressure, reducing the ingress of external water and further improving the sealing effect.
[0031] 3. By setting up lateral support wheels, excessive shaking of the door body is reduced, and excessive compression damage to the water-stop seal is reduced, so that the sealing effect can be maintained. Attached Figure Description
