Description

Technical Field

[0001] The present invention relates to the technical field of flood control water retaining devices, and specifically relates to a flood control water retaining device for water conservancy projects. Background Art

[0002] In the patent application with the application publication number CN221798301U, it includes a vertical plate. A water bag is detachably connected to the back water surface of the vertical plate. The vertical plate is provided with a water inlet hole and an overflow hole. The overflow hole is located above the water inlet hole, and a water inlet channel is provided in the water inlet hole. A first piston is slidably arranged in the water inlet hole. When the first piston slides in the water inlet hole, the water inlet channel can be opened or closed. A warning plate is slidably connected in the vertical plate. The warning plate is connected to the vertical plate through a first spring. A second clamping block for limiting the warning plate is slidably connected to the vertical plate. A float is slidably connected in the vertical plate. The float can drive the second clamping block to move so as to release the limitation on the warning plate. The advantages are as follows: When water flows into the vertical plate through the overflow hole, the float can be further lifted at this time. When the float rises to a sufficient height, the ejector rod can push the sliding rod to move, and the sliding rod pushes the second clamping block out of the sliding hole. At this time, under the action of the first spring, the warning plate can be driven to rise. When the water volume is too high, the warning plate can automatically rise, and warning can be carried out at this time, which is convenient for river patrol personnel to detect flood conditions in time.

[0003] In the above-mentioned patent and the prior art, the design of the water retaining plate allows it to be independently supported and can stand stably even on a flat ground. When a flood comes, the upper part of the water retaining plate is pressed by the flood, and the lower part is fixed by a stable rubber material. Utilizing the gravity of the fluid itself and changing the direction of the water flow, the L-shaped water retaining plate has become an efficient and temporary flood control solution. However, in actual use, due to the blockage of the water flow or rainfall, etc., the subsequent water flow will continue to increase, resulting in a rising water level. When the water level rises, most of the existing patents improve the structure by increasing the weight, etc. The most important point of the L-shaped water retaining plate is to use the water pressure for stability, and the change of weight does not have much practical significance. Summary of the Invention

[0010] Preferably, a plurality of gears are rotatably provided in a straight line between the front and back of the bottom of the inner wall of the water baffle, a reinforcing rod is fixedly provided on the back of the gear, and the gear is meshed with the toothed plate and the flexible plate.

[0013] Preferably, the hook is adapted to the card slot, and an auxiliary rod is rotatably provided at the bottom of one side of the water baffle, and a torsion spring is provided at the rotating connection of the auxiliary rod and the water baffle.

[0014] Preferably, a reinforcing rib is fixedly provided on one side of the water baffle, an arc plate is provided at the bent part of the water baffle, connecting plates are rotatably provided on both sides of the front side of the top of the water baffle, fixing screws penetrate through the top of the connecting plates, and connecting holes are opened on both sides of the rear side of the top of the water baffle, and the connecting holes are threadedly connected with the fixing screws.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0016] (1) The water baffle is internally provided with a reinforcement structure and a control structure, which can be used in cooperation with each other. When the water baffle blocks the water flow, as the water level rises, the floating plate can be used to sense the water level height. When the water level is about to exceed the limit height of the water baffle, the floating plate will drive the moving plate to move upward to increase the overall height of the water baffle, further blocking the water flow. At the same time as the moving plate rises, it will also trigger the movement of the toothed plate in the reinforcement structure. The movement of the toothed plate can increase the pressure-bearing area at the bottom of the water baffle and further increase the stability of the water baffle. In essence, while increasing the height of the water baffle, the bottom area is also increased. This device can also be reused. After the water level drops and the water baffle is recycled and before reuse, the moving plate and the toothed plate can be reset through the pull ring. The overall structure is simple, the cooperation is tight, and it is further enhanced according to the characteristics of the water baffle itself, making it more stable and adaptable. There is also a color leakage plate on the moving plate, which can increase the warning after the water level rises. Since the water flow may be relatively turbulent and the color is relatively deep, the color warning on the water baffle body is not obvious enough. When there is water flow passing through the color leakage plate, it will react with the water to emit color and dye the passing water flow. When the water flow changes color on a large scale, the observer can quickly discover the change in the water level;

[0017] (2) One side of the water baffle is also provided with a support plate that can be controlled to be locked and released by the moving plate. After the moving plate moves upward, it proves that the water level has become higher and the water flow impact is greater. At this time, the support plate automatically sprung open by the torsion spring can increase the support at the bottom of the water baffle, preventing the water flow from knocking down the water baffle. The overall resistance of the water baffle is further enhanced through the triangular stability principle. The simple snap design can also make it reusable. There are also a connecting plate and a connecting hole on the top of the water baffle. According to actual use needs, several water baffles can be connected together, turning a single plate body into a connected plate body, which can better cope with the water flow impact and make the fit between the plates closer to avoid water leakage.

[0038] A tension pulley 404 is rotatably provided at the bottom of the inner wall of the water retaining plate 2. Sliders 402 are provided on both the front and back of the toothed plate 401. Sliding grooves are opened on both the front and back of the bottom of the inner wall of the water retaining plate 2, and the sliding grooves are adapted to the sliders 402.

[0039] A rotating shaft 9 is provided at the bottom of one side of the water retaining plate 2. A support plate 10 is rotatably provided at the bottom of the rotating shaft 9. A torsion spring is provided at the axis of the rotating shaft 9. A support foot 11 is rotatably provided at the bottom of the support plate 10. A hook 13 is fixedly provided on one side of the support plate 10. A storage groove is opened on one side of the support plate 10.

[0040] The hook 13 is adapted to the card slot 505. An auxiliary rod 12 is rotatably provided at the bottom of one side of the water retaining plate 2. A torsion spring is provided at the rotation connection of the auxiliary rod 12 and the water retaining plate 2.

[0041] One side of the water baffle 2 is fixedly provided with a reinforcing rib 1. An arc-shaped plate 6 is provided at the bent portion of the water baffle 2. Connecting plates 7 are rotatably provided on both sides of the front side of the top of the water baffle 2. Fixing screws 8 penetrate through the tops of the connecting plates 7. Connecting holes 3 are opened on both sides of the rear side of the top of the water baffle 2, and the connecting holes 3 are in threaded connection with the fixing screws 8.

[0042] The working principle and usage process of the present invention: When blocking the water flow, the user can choose whether to connect several water baffles 2 together according to the actual situation. When connection is required, rotate the connecting plate 7 by 180° and then rotate and tighten the fixing screw 8 with the connecting hole 3 to connect two water baffles 2 together. Similarly, it can also be used individually. When the water flow passes through the water baffle 2, the water baffle 2 will be fixed in place by the pressure of the water flow. In the initial stage, the water flow rate is small, and when the water flow rate becomes larger later, the water level will rise synchronously. When the water level is higher than the water baffle 2, the floating plate 506 will be forced to move upward with the water level. The floating plate 506 drives the moving plate 503 to move synchronously. When the moving plate 503 moves to a certain height, the color leakage plate 502 will be exposed. After the color leakage plate 502 comes into contact with the water flow, it will emit a striking color, and this color will spread in the water to form area-type color change. The observer on the shore can quickly know that the water level has risen to the warning position after noticing the color change on the water surface. As the floating plate 506 and the moving plate 503 move upward, they will also drive the flexible plate 504 at their bottom to move. The flexible plate 504 drives the gear 403 to rotate through the teeth on its top. The rotation of the gear 403 drives the toothed plate 401 to move along the chute and extend to one side. The extended toothed plate 401 will increase the pressure-bearing area at the bottom of the water baffle 2, making the whole water baffle 2 more stable. While the moving plate 503 moves, it will also drive the card slot 505 to move upward. After the hook 13 loses its connection, the support plate 10 will open outward through the torsion spring at the connection with the rotating shaft 9. At the same time of opening, the restraint on the auxiliary rod 12 is lost, and the auxiliary rod 12 will also open through the torsion spring to support the support plate 10. This can prevent the stability of the water baffle 2 from decreasing due to the rising water level and further increase the overall resistance of the water baffle 2. After the water level drops, when recovering the water baffle 2, the water baffle 2 can be tilted to pull the pull ring 501 at its bottom. The pull ring 501 can drive the flexible plate 504 to move to one side. When the moving plate 503 returns to the initial position, the toothed plate 401 will also contract back to its original position due to the reverse rotation of the gear 403. After folding the support plate 10 and reinserting it into the card slot 505, the water baffle 2 can be restored to its initial state and wait for the next use.

[0043] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
