Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a hydraulic steel gate with a rapid water-stopping device. Background Technology

[0002] In the field of water conservancy engineering, hydraulic steel gates play a crucial role, serving as the core component for controlling water flow in various water conservancy facilities. They are widely used in water conservancy projects such as reservoirs, sluices, ship locks, and hydropower stations, undertaking important tasks such as regulating water levels, controlling flow, and discharging floodwaters. They are indispensable for ensuring the safe operation of water conservancy projects, the rational allocation of water resources, and the realization of flood control, irrigation, navigation, and power generation functions in surrounding areas.

[0003] When a gate is subjected to a large impact force, the gate plate will experience slight displacement or vibration. Traditional water-stopping materials and sealing structures cannot compensate for these changes in time. Ordinary rubber waterstops, when the gate is pressed down, cannot automatically adjust their shape and tightness according to the dynamic changes of the gate plate, resulting in gaps in local areas and water leakage. Even if multiple sealing lines are used, during the rapid pressing of the gate, the various lines of defense are difficult to quickly coordinate and adapt to the dynamic changes brought about by the impact force, and cannot effectively prevent instantaneous leakage.

[0004] Therefore, this application provides a hydraulic steel gate with a quick-closing device to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a hydraulic steel gate with a rapid water-stopping device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a hydraulic steel gate with a rapid water-stopping device, comprising:

[0007] outer frame;

[0008] A water-stopping assembly is placed inside an outer frame. The water-stopping assembly includes a gate body slidably connected inside the outer frame, a water-leaking cylinder slidably connected to the gate body, a first fan blade rotatably connected inside the water-leaking cylinder, a connecting rod fixedly connected to the water-leaking cylinder, a second sliding shaft fixedly connected to the connecting rod, a transmission block slidably connected to the second sliding shaft, a rubber sealing gasket fixedly connected to the transmission block, and a first sliding shaft fixedly connected to the rubber sealing gasket. The first sliding shaft is slidably connected inside the outer frame.

[0009] A drive shaft is placed inside the outer frame. The drive shaft includes a drive shaft rotatably connected to a drive block, and a second fan blade is fixedly connected to the drive shaft.

[0010] In a preferred embodiment, the first fan blade is rotatably connected to the drain tube via a rotating shaft.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting the first fan blade to be rotatably connected inside the water leakage cylinder, when the water flows through and impacts the first fan blade, the first fan blade will rotate and push the water leakage cylinder to move closer to the transmission block through the rotating shaft.

[0012] In a preferred embodiment, a damper is fixedly connected to the transmission block, and the end of the damper away from the transmission block is fixedly connected to the water leakage cylinder.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by fixing a damper to the transmission block, a slight pulling force can be provided to the transmission block during use, preventing the transmission block from directly detaching the rubber sealing gasket.

[0014] In a preferred embodiment, the transmission block is provided with an inclined groove, and the second sliding shaft is slidably connected in the inclined groove on the transmission block.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by opening a slanted groove on the transmission block, it is convenient for the second sliding shaft to drive the transmission block during use. When the second sliding shaft slides to the raised part of the slanted groove on the transmission block, it will press down on the transmission block, causing it to slide downward on the outer frame.

[0016] In a preferred embodiment, grooves are provided at both ends of the drive shaft.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: By providing grooves at both ends of the drive shaft, it is convenient to connect the flexible steel wire rope during use. The other end of the flexible steel wire rope is wound around the rotating shaft. When the water flow pushes the leakage cylinder to a certain distance, before the second sliding shaft abuts against the edge of the drive block, the drive shaft will be driven to rotate by the water flow, causing the flexible steel wire rope to wind around the drive shaft. This ensures that the flexible steel wire rope winds around the rotating shaft in time, preventing excessive displacement that could cause the leakage cylinder to detach from the gate body.

[0018] In a preferred embodiment, a rubber sleeve is fixedly connected to the side of the water leakage cylinder away from the transmission block, and the rubber sleeve on the water leakage cylinder is slidably connected to the gate body.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by fixing a rubber sleeve on the side of the water leakage cylinder away from the transmission block, the rubber sleeve will press against the gate body during use, further preventing the water leakage cylinder from shifting.

[0020] In a preferred embodiment, the transmission block is fixedly connected to the first sliding shaft by bolts, and the bolts on the transmission block are slidably connected to the gate body.

[0021] The beneficial effects of adopting the above-mentioned further solution are: by setting bolts on the transmission block, it is convenient for the transmission block to drive the first sliding shaft to move downward during use. The gate body is set as a hollow structure, and an opening is opened on the side of the gate body near the transmission block for the bolts on the transmission block to slide, so as not to affect the sealing performance.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, when the gate is pressed down, the water flow impacts the leaking cylinder. With the help of the rotation of the first blade and the linkage between various components, such as the leaking cylinder driving the second sliding shaft to slide in the inclined groove of the transmission block through the connecting rod, the transmission block is pressed down, which in turn drives the rubber sealing gasket to press down. This can dynamically improve the sealing effect of the outer frame according to the force of the water flow during the gate pressing down. It changes the traditional water-stopping structure that relies solely on static bonding for sealing. The sealing process can be adjusted in real time according to the water flow and the gate pressing down, effectively dealing with the slight displacement or vibration of the gate plate when subjected to a large impact force. It avoids the problem of local gaps and water leakage caused by the inability of ordinary rubber waterstops to adapt to the dynamic changes of the gate plate. Thus, it effectively prevents instantaneous leakage and makes up for the shortcomings of traditional multi-layer sealing defenses that are difficult to work quickly and collaboratively during dynamic pressing down.

[0024] In this invention, grooves are provided at both ends of the drive shaft to connect flexible steel wire ropes, and the other end of the steel wire ropes is wound around the shaft. This prevents the water flow from excessively displacing the leaking cylinder and causing it to detach from the gate body, maintaining a reasonable connection and stable relative position between the components of the entire water-stopping assembly, and ensuring that the sealing structure can continue to function. Simultaneously, a rubber sleeve is installed on the leaking cylinder to abut against the gate body, further limiting the displacement of the leaking cylinder and strengthening the overall stability from a structural perspective, thus contributing to better water-stopping and sealing performance.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0035] like Figure 1-5 As shown, this utility model provides a technical solution: a hydraulic steel gate with a rapid water-stopping device, comprising:

[0036] Outer frame 1;

[0037] Water-stopping component 2 is placed inside the outer frame 1. The water-stopping component 2 includes a gate body 23 slidably connected inside the outer frame 1, a water-leaking cylinder 21 slidably connected to the gate body 23, a first fan blade 22 rotatably connected inside the water-leaking cylinder 21, a connecting rod 29 fixedly connected to the water-leaking cylinder 21, a second sliding shaft 27 fixedly connected to the connecting rod 29, a transmission block 26 slidably connected to the second sliding shaft 27, a rubber sealing gasket 25 fixedly connected to the transmission block 26, a first sliding shaft 24 fixedly connected to the rubber sealing gasket 25, and the first sliding shaft 24 slidably connected inside the outer frame 1.

[0038] The transmission shaft 3 is placed inside the outer frame 1. The transmission shaft 3 includes a transmission shaft 3 that is rotatably connected to the transmission block 26. A second fan blade 31 is fixedly connected to the transmission shaft 3.

[0039] In this invention, when the gate is pressed down, the water flow impacts the water-leaking cylinder 21. With the help of the rotation of the first fan blade 22 and the linkage between various components, such as the water-leaking cylinder 21 driving the second sliding shaft 27 to slide in the inclined groove of the transmission block 26 through the connecting rod 29, the transmission block 26 is pressed down, which in turn drives the rubber sealing gasket 25 to press down. This can dynamically improve the sealing effect of the outer frame 1 according to the force of the water flow during the gate pressing down. It changes the traditional water-stopping structure that relies solely on static bonding for sealing. The sealing process can be adjusted in real time according to the water flow and the gate pressing down, effectively dealing with the slight displacement or vibration of the gate plate when subjected to a large impact force. It avoids the problem of local gaps and water leakage caused by the inability of ordinary rubber waterstops to adapt to the dynamic changes of the gate plate. Thus, it effectively prevents instantaneous leakage and makes up for the shortcomings of traditional multi-layer sealing defenses that are difficult to work quickly and collaboratively during dynamic pressing down.

[0040] Furthermore, such as Figures 1 to 5 As shown, the first fan blade 22 is rotatably connected to the water leakage cylinder 21 via the rotating shaft 28. By setting the first fan blade 22 to be rotatably connected to the water leakage cylinder 21, when water flows through and impacts the first fan blade 22 during use, the first fan blade 22 will rotate and push the water leakage cylinder 21 to move closer to the transmission block 26 via the rotating shaft 28.

[0041] A damper is fixedly connected to the transmission block 26. The end of the damper on the transmission block 26 away from the transmission block 26 is fixedly connected to the water leakage cylinder 21. By fixing the damper to the transmission block 26, a slight pulling force can be provided to the transmission block 26 during use, so as to prevent the transmission block 26 from driving the rubber sealing gasket 25 to fall off directly.

[0042] The transmission block 26 has a sloping groove, and the second sliding shaft 27 is slidably connected in the sloping groove on the transmission block 26. By having a sloping groove on the transmission block 26, it is convenient for the second sliding shaft 27 to drive the transmission block 26 during use. When the second sliding shaft 27 slides to the raised part of the sloping groove on the transmission block 26, it will press down on the transmission block 26, causing it to slide downward on the outer frame 1.

[0043] Both ends of the drive shaft 3 are provided with grooves. By providing grooves at both ends of the drive shaft 3, it is convenient to connect the flexible steel wire rope during use. The other end of the flexible steel wire rope is wound around the rotating shaft 28. When the water flow pushes the water leakage cylinder 21 to a certain distance, before the second sliding shaft 27 abuts against the edge of the drive block 26, the drive shaft 3 will be driven to rotate by the water flow, so that the flexible steel wire rope is wound around the drive shaft 3. This allows the flexible steel wire rope to wrap around the rotating shaft 28 in time, preventing it from displacing excessively and causing the water leakage cylinder 21 to detach from the gate body 23.

[0044] A rubber sleeve is fixedly connected to the side of the water leakage cylinder 21 away from the transmission block 26. The rubber sleeve on the water leakage cylinder 21 is slidably connected to the gate body 23. By fixing the rubber sleeve on the side of the water leakage cylinder 21 away from the transmission block 26, the rubber sleeve will press against the gate body 23 during use, further preventing the water leakage cylinder 21 from shifting.

[0045] The above solution also has the problem of not clearly defining the connection method between the bolts and the gate body 23, requiring the gate body 23 to have pre-reserved sliding holes, which could lead to water leakage. Figure 1 , Figure 3 , Figure 5 As shown, the transmission block 26 is fixedly connected to the first sliding shaft 24 by bolts. The bolts on the transmission block 26 are slidably connected to the gate body 23. By providing bolts on the transmission block 26, it is convenient for the transmission block 26 to drive the first sliding shaft 24 to move downward during use. The gate body 23 is set as a hollow structure. An opening is provided on the side of the gate body 23 near the transmission block 26 for the bolts on the transmission block 26 to slide, so as not to affect the sealing performance.

[0046] Working principle: such as Figure 1-5 As shown,

[0047] When in use, first fix the flexible steel wire rope in the groove on the drive shaft 3, and then wrap and fix the end of the flexible steel wire rope away from the drive shaft 3 to the rotating shaft 28. The staff can install the hydraulic telescopic rod between the outer frame 1 and the gate body 23 according to the actual situation.

[0048] Then, the hydraulic telescopic rod is activated, causing the hydraulic telescopic rod to push down the gate body 23. At this time, the water flow impacts the water leakage cylinder 21, causing the water leakage cylinder 21 to be moved closer to the transmission block 26 under the action of the first fan blade 22. During this process, the water leakage cylinder 21 drives the second sliding shaft 27 to slide in the inclined groove of the transmission block 26 through the connecting rod 29, causing the transmission block 26 to press down a small distance. The transmission block 26 drives the rubber sealing gasket 25 to press down through the bolt, thereby improving the sealing effect of the outer frame 1.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
