Description

Technical Field

[0001] This utility model relates to the field of gate technology, specifically to a working gate leaf with a multi-layer water-stopping structure. Background Technology

[0002] The gate leaf of a working gate is a key component used in water conservancy projects, river regulation, irrigation systems, ports, and other locations, primarily serving to control water flow. It is typically made of metal materials (such as steel plates or cast iron), and its shape and structural design can be adjusted to meet different needs. The gate leaf adjusts its opening and closing according to changes in water flow, ensuring that the flow rate, direction, or water level is controlled. A multi-layered water-stopping structure effectively improves the gate's sealing performance, preventing water leakage through joints or structural gaps. This is crucial for controlling water flow, preventing water pollution, and reducing water waste; therefore, a multi-layered water-stopping structure is needed for the gate leaf of a working gate.

[0003] The environmental conditions of water conservancy projects are complex and changeable. Factors such as water level, temperature and flow velocity can affect the gates to varying degrees. Under different hydrological conditions, the working gates face greater water pressure. Especially under high water head (such as high water level or high flow conditions), a single water-stopping structure may not be able to effectively withstand the pressure. Utility Model Content

[0004] This utility model proposes a multi-layered water-stopping structure for the gate leaf of a working gate, which solves the problem that the environmental conditions of water conservancy projects are complex and changeable, and factors such as water level, temperature, and flow velocity will have different degrees of impact on the gate. Under different hydrological conditions, the working gate faces greater water pressure, especially under high water head (such as high water level or high flow conditions), where a single water-stopping structure may not be able to effectively withstand the pressure.

[0005] The technical solution of this utility model is as follows: A working gate leaf with a multi-layer water-stop structure includes a gate body, characterized in that it further includes a first fixed wheel, a second fixed wheel, a side wheel, bolts, a gate body, a top side water-stop double plate, a top side water-stop pad, a top side water-stop pressure plate, a first bolt, a reverse slider, a second bolt, a third bolt, a stop plate, a bottom water-stop plate, a bottom water-stop pressure plate, a fourth bolt, and rubber pads. The first fixed wheel is installed on the side of the gate body, a second fixed wheel is provided on one side of the first fixed wheel, a side wheel is installed on the upper right side of the second fixed wheel, and bolts are installed on the outer side of the side wheel.

[0006] Preferably, the door body is provided with a top-side water-stop double plate on its side, a top-side water-stop pad is provided on the top of the top-side water-stop double plate, a top-side water-stop pressure plate is provided above the top-side water-stop pad, a first bolt is provided on the outer side of the top-side water-stop pressure plate, a reverse slider is provided on the right side of the door body, a second bolt is installed on the inner side of the reverse slider, a third bolt is installed on the side of the top-side water-stop double plate, a stop plate is provided on the top of the reverse slider, a bottom water-stop plate is provided at the bottom of the door body, a bottom water-stop pressure plate is provided on the bottom side of the bottom water-stop plate, and a fourth bolt is installed on the outer side of the bottom water-stop pressure plate.

[0007] Preferably, the door body has a size in the X ratio, and the first fixed wheel and the second fixed wheel are obliquely installed on the side of the door body and have different sizes. The first fixed wheel is [size missing] and the second fixed wheel is [size missing].

[0008] Preferably, the side wheel is fixed by bolts, the top side water-stop double plate, pad plate and pressure plate are stacked in sequence and pressed together by the first bolt, the reverse slider is fixed to the right side of the door by the second bolt, a stop plate is provided at the top, and the bottom water-stop plate and pressure plate are clamped together by the fourth bolt to hold the rubber pad.

[0009] Preferably, the top-side water-stop double plate and the pad form a stepped sealing cavity, the reverse slider contact surface is provided with a longitudinal groove, and the rubber pad is made of EPDM rubber.

[0010] The working principle and beneficial effects of this utility model are as follows:

[0011] Through the stepped sealing cavity design, the stacking of the top-side double water-stop plates, water-stop pads, and pressure plates forms a multi-layered sealing structure, effectively preventing water leakage. This design not only enhances the stability of the seal but also allows it to withstand greater water pressure, preventing seal failure.

[0012] The bottom water-stop structure is similar to the top structure. The bottom water-stop plate, bottom water-stop pressure plate and rubber gasket are pressed together to form a tight sealing cavity, which effectively prevents water from seeping in from the bottom. The use of fixed wheels of different sizes and tilt angles (first fixed wheel and second fixed wheel) can balance the pressure on the door body during operation, reduce local pressure concentration, and reduce the risk of damage or instability caused by uneven force. The use of bolts in different parts ensures a tight connection between the components, avoids loosening or displacement of the components, and thus improves the overall stability of the door leaf structure.

[0013] The design of the reverse slider, in conjunction with the longitudinal grooves, facilitates water drainage, prevents moisture buildup, and avoids excessive friction between the slider and other components. This not only improves the smoothness of the door's sliding but also prevents seal failure or structural damage caused by water accumulation. Attached Figure Description

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution for a multi-layered water-stopping structure working gate leaf: including a gate body 5, characterized in that it further includes a first fixed wheel 1, a second fixed wheel 2, a side wheel 3, a bolt 4, a gate body 5, a top side water-stopping double plate 6, a top side water-stopping pad 7, a top side water-stopping pressure plate 8, a first bolt 9, a reverse slider 10, a second bolt 11, a third bolt 12, a stop plate 13, a bottom water-stopping plate 14, a bottom water-stopping pressure plate 15, a fourth bolt 16, and a rubber pad 17. The first fixed wheel 1 is installed on the side of the gate body 5, the second fixed wheel 2 is provided on one side of the first fixed wheel 1, the side wheel 3 is installed on the upper right side of the second fixed wheel 2, and the bolt 4 is installed on the outer side of the side wheel 3.

[0022] The door body 5 is equipped with a double top-side water-stop plate 6 on its side. A top-side water-stop pad 7 is placed on top of the double top-side water-stop plate 6. A top-side water-stop pressure plate 8 is placed above the top-side water-stop pad 7. A first bolt 9 is placed on the outer side of the top-side water-stop pressure plate 8. The stacking of the double top-side water-stop plate 6, pad 7, and pressure plate 8 forms a stepped sealing cavity, which can more effectively improve the sealing effect. The stepped design helps to prevent water leakage and ensures a more secure and stable seal.

[0023] Tightening effect: Tightening these components with the first bolt 9 helps to enhance the sealing performance and prevent moisture from penetrating into the door body.

[0024] A reverse slider 10 is installed on the right side of the door body 5. A second bolt 11 is installed on the inner side of the reverse slider 10. A third bolt 12 is installed on the side of the top water-stop double plate 6. A stop plate 13 is installed on the top of the reverse slider 10. A bottom water-stop plate 14 is installed at the bottom of the door body 5. A bottom water-stop pressure plate 15 is installed on the bottom side of the bottom water-stop pressure plate 14. A fourth bolt 16 is installed on the outer side of the bottom water-stop pressure plate 15. By stacking and being pressed together by the first bolt 9, a sealed cavity is formed. The purpose is to form a multi-layer sealing structure by using the pressure when the door is closed, effectively preventing water seepage. The bottom water-stop structure is similar to the top structure, using the fourth bolt 16 to clamp the rubber gasket 17. The rubber gasket 17 is made of EPDM rubber, which has good elasticity and sealing performance, ensuring effective waterproofing under different pressures.

[0025] The door body 5 has a size of 4.6 x 4.6. The first fixed wheel 1 and the second fixed wheel 2 are installed at an angle on the side of the door body 5 and are different in size. The first fixed wheel 1 is 550 and the second fixed wheel 2 is 650. The different sizes of the first fixed wheel 1 and the second fixed wheel 2 can balance the pressure distribution of the door body during use and reduce damage or instability caused by uneven force.

[0026] The side wheel 3 is fixed by bolts 4. The top side water-stop double plate 6, pad 7, and pressure plate 8 are stacked in sequence and pressed together by the first bolt 9. The reverse slider 10 is fixed to the right side of the door body 5 by the second bolt 11. A stop plate 13 is provided at the top. The bottom water-stop plate 14 and pressure plate 15 are clamped together by the fourth bolt 16 to hold the rubber pad 17. The application of various bolts in different parts (such as the top side water-stop double plate, reverse slider, bottom water-stop plate, etc.) ensures the stable connection between the components, avoids loosening or displacement, and improves the stability and sealing of the overall structure.

[0027] The top-side water-stop double plates 6 and the pad 7 form a stepped sealing cavity. The contact surface of the reverse slider 10 has longitudinal grooves. The groove design facilitates water drainage, prevents moisture accumulation, and avoids excessive friction between the slider and other components. The grooves also help maintain smooth sliding. The rubber pad 17 is made of EPDM rubber, which has excellent anti-aging, high temperature resistance, low temperature resistance, water resistance, and chemical corrosion resistance. It can effectively prevent the seal from being damaged by changes in the external environment and maintain long-term sealing performance.

[0028] Working principle: When the gate is closed, the top and bottom waterstop plates, pressure plates, pads, and reverse sliders form a sealed area. This multi-layered sealing structure ensures isolation between the gate and the water surface, preventing water seepage. The cooperation of the fixed and side rollers ensures smooth, unobstructed opening and closing of the gate, while bolts and reverse sliders provide additional sealing pressure and mechanical support. The grooved design of the reverse slider and the use of sealing gaskets further enhance the gate's waterproofing and sealing performance.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
