Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of non-powered flip-type flood control baffles, specifically a non-powered flip-type flood control baffle. Background Technology
[0002] The non-powered tilting flood barrier is an automatic flood control device based on a mechanical structure design. Its core lies in its ability to achieve rapid tilting and sealing without relying on external power (such as electricity or hydraulics), through the coordinated action of water pressure, buoyancy, and a spring mechanism. The device mainly consists of a fixed base, a movable water-blocking plate, a leaf spring mechanism, an arc-shaped pressure plate, and a locking assembly. The base is fixed to the ground or the entrance / exit of an underground space. One end of the water-blocking plate is connected to the base via a pivot, while the other end maintains a gap with the ground when not triggered. The leaf spring mechanism provides the tilting torque, the arc-shaped pressure plate ensures a stable tilting trajectory, and the locking mechanism is used to fix the barrier during non-flood seasons. When floods occur, water flows through the gap at the bottom of the barrier, causing it to rise due to buoyancy. Simultaneously, the elastic force of the leaf spring assists it in tilting along a predetermined arc path to a vertical position, forming a sealing barrier. Some designs directly push the barrier with water pressure, using the impact force of the water flow to complete the closure. The barrier edges are equipped with L-shaped water-blocking strips and sealing strips, which, combined with the water storage spaces on both sides of the base, enhance the sealing performance and effectively prevent leakage. This device is suitable for low-lying areas such as underground parking lots, subway stations, and substations, and can respond to floods within seconds, combining speed and reliability. Its advantages include no power dependence, simple structure, low maintenance costs, and the baffle can be placed horizontally or embedded in a ground trench during non-flood seasons without affecting passage. To further improve performance, some improvements use corrosion-resistant alloys or composite materials to extend lifespan, or integrate water level sensors for remote status monitoring, but the core remains purely mechanically driven to ensure stable operation during power outages or in harsh environments.
[0003] Traditional devices require water pressure and buoyancy as conditions to trigger the baffle to flip. When the water volume is insufficient, the baffle usually cannot be opened, which restricts the flexibility of the device. When the flood is strong, water backflow is likely to occur. Moreover, during the deployment of this type of device, the traction rod often slides inside the chute. If sand and gravel get stuck, it can easily lead to deployment difficulties.

[0004] The purpose of this utility model is to provide a non-powered flip-type flood control baffle to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-powered flip-type flood control baffle, comprising a cement foundation and a slope set on one side of the cement foundation, wherein a triggering mechanism and a supporting drainage mechanism are provided inside the cement foundation, and the supporting drainage mechanism is set inside the triggering mechanism;
[0006] The triggering mechanism includes a water collection channel, which is located inside a concrete foundation. A support frame is fixedly connected inside the concrete foundation and is fixedly connected to the upper side of the water collection channel. Sliding grooves are formed inside both sides of the concrete foundation, and sliding rods are slidably connected inside the sliding grooves. A stop block is fixedly connected to the inner side of the sliding rod, and a rotating rod is fixedly connected to the lower side of the stop block. The rotating rod is rotatably connected inside the concrete foundation. A pressure transmitting pipe is fixedly connected to one side of the stop block, and a slider is slidably connected to one side of the slider. A thin plate is connected to the outer wall of the pressure transmission pipe in a sealed sliding connection. A pressure-bearing plate is slidably connected inside the cement foundation. The pressure-bearing plate is located below the water collection channel. A support column is fixedly connected to the lower side of the pressure-bearing plate. A sliding plate is fixedly connected to the lower side of the support column. A piston cylinder is sleeved on the outer side of the sliding plate. A return spring is fixedly connected between the inner wall of the piston cylinder and the sliding plate. A pressure-transferring pipe is connected between the lower interior of the piston cylinder and the pressure transmission pipe. A gull-shaped discharge port is opened on one side of the cement foundation. The discharge port is located below the pressure-bearing plate.
[0007] Preferably, the upper end of the thin plate has an inclined surface structure.
[0008] Preferably, the slider has a square cross-section.
[0009] Preferably, the thin plate has a cylindrical cavity inside.
[0010] Preferably, the supporting drainage mechanism includes a rotating seat, which is fixedly connected to one side of the stop block. A flow transfer cavity is formed inside the cement foundation. A limit rod is fixedly connected to the inner wall of the flow transfer cavity. A sliding column is fixedly connected to one end of the limit rod. The sliding column is fixedly connected to the inner wall of the cement foundation. A sliding ring is slidably connected to the outer wall of the sliding column.

[0012] Preferably, multiple connecting rods are provided, and the connecting rods are evenly distributed inside the transfer cavity.
[0013] Compared with the prior art, this utility model provides a non-powered flip-type flood baffle, which has the following beneficial effects:
[0014] 1. The triggering mechanism is used to quickly deploy the baffle. This mechanism uses water pressure to extend the thin plate, which can increase the water pressure utilization effect and reduce the pressure requirement. After the thin plate is extended, it forms an angle with the ground. At this time, the thin plate can block the water flow and reduce the deployment time. The baffle can be fully deployed by the impact force of the water flow, so as to block large floods in time.
[0015] 2. The supporting drainage mechanism is used to pull the baffle to disperse the pressure of the baffle and release the flood. Compared with traditional equipment, which generally relies on buoyancy and water pressure to deploy the baffle, the flood cannot be discharged in time, so as to avoid insufficient triggering force and difficulty in deployment. This mechanism uses pressure and impact force as the deployment method. At the same time, the mechanism uses a thin plate as an auxiliary triggering element, which reduces the conditions required for deployment, so as to facilitate the discharge of flood and reduce the impact force, and also avoids the situation where sand and gravel are stuck and difficult to open.
