Description

Technical Field

[0001] This utility model relates to the field of steel dam gate technology, and in particular to a high-efficiency water-stopping and sealing device for hydraulic steel dam gates. Background Technology

[0002] A hydraulic steel dam gate, or simply a hydraulic dam, is a water-retaining structure that uses hydraulic cylinders to drive and combines with steel dam panels to form a movable dam face. It utilizes hydraulic technology to raise and lower the dam face, thereby controlling the flow and water level of a river. A hydraulic steel dam gate typically consists of a dam face, a hydraulic drive system, a control system, and safety protection devices.

[0003] Currently, a Chinese patent discloses a novel inflatable top-stopping device for steel dam gates (authorization announcement number CN217104979U). This invention includes a gate frame, with a steel dam gate connected to the gate frame via a rotating shaft. A hydraulic cylinder is connected to one side of the gate frame via a fixed seat. The output end of the hydraulic cylinder is connected to a telescopic column via a rotating component. The telescopic column is connected to a fixed cylinder via a time-delay drive assembly. This invention delays the linkage between the hydraulic cylinder and the gate by setting a telescopic column and a fixed cylinder between them. After the gate closes, air pressure moves the rubber inflatable pad on the outer wall of the gate outward, sealing the gap at the gate and preventing wear on the rubber inflatable pad due to the opening and closing of the gate, thus ensuring a good sealing effect. However, this method has the following drawback in actual use: it cannot seal the gaps between the gate and the side wall of the gate frame. Utility Model Content

[0004] Therefore, it is necessary to provide a high-efficiency water-stopping and sealing device for hydraulic steel dam gates to address the problem of not being able to seal the gaps in the gate and the side wall of the gate frame.

[0005] A high-efficiency water-stopping and sealing device for a hydraulic steel dam gate includes: a gate frame, on which a steel dam gate is rotatably connected; a hydraulic drive device for rotating the steel dam gate is installed on the gate frame; and a water-stopping mechanism for sealing the gap between the gate frame and the steel dam gate is installed on the gate frame. The water-stopping mechanism includes water-blocking vertical plates symmetrically arranged on the gate frame, and a water-blocking horizontal plate fixedly connected to one side of the two water-blocking vertical plates at a lower position. A sealing strip is fixedly connected to the water-blocking vertical plates and the water-blocking horizontal plate on the same side.

[0006] In one embodiment, the vertical water-blocking plate is triangular in shape, and the horizontal water-blocking plate is fixedly connected to a water-guiding slope on the side away from the sealing strip.

[0007] In one embodiment, the sealing strip is configured as a corrosion-resistant sealing strip, and a plurality of the sealing strips are disposed on the side of the water-retaining vertical plate and the water-retaining horizontal plate near the steel dam gate.

[0008] In one embodiment, a sealing mechanism is provided on the gate frame, the sealing mechanism including a sealing air pad installed on the gate frame, an air compressor and an air storage tank are fixedly installed on the gate frame, and the air storage tank is in communication with the sealing air pad.

[0009] In one embodiment, the air compressor is connected to an air storage tank, and a pressure gauge is installed on the air storage tank.

[0010] In one embodiment, the gate frame sidewall and bottom are provided with limiting grooves corresponding to the sealing air pad, and the steel dam gate sidewall and bottom are also provided with limiting grooves.

[0011] In one embodiment, the sealing air pad is configured as a corrosion-resistant air pad, and the sealing air pad has the same shape as the sealing strip.

[0012] In one embodiment, the sealing inflatable pad is provided with an exhaust pipe, and the exhaust pipe is provided with an electric valve.

[0013] Beneficial effects

[0014] A water-stopping mechanism is installed. When the hydraulic drive device moves the steel dam gate toward the water-blocking horizontal plate and water-blocking vertical plate, the steel dam gate comes into contact with the sealing strip. The pressure of the steel dam gate squeezes the sealing strip, causing it to deform and forming a seal between the steel dam gate and the water-blocking vertical plate and water-blocking horizontal plate, thus preventing water leakage.

[0015] Air is injected into the air tank by an air compressor, and then high-pressure gas is injected into the sealing gasket through the air tank, causing the sealing gasket to expand and fill the limiting groove, forming a secondary seal and further improving the sealing effect.

[0028] The following is combined with Figures 1-4 This invention describes a high-efficiency water-stopping and sealing device for a hydraulic steel dam gate.

[0029] In one embodiment, a high-efficiency water-stopping sealing device for a hydraulic steel dam gate includes: a gate frame 100, a steel dam gate 110 rotatably connected to the gate frame 100, a hydraulic drive device 111 installed on the gate frame 100 to drive the steel dam gate 110 to rotate, and a water-stopping mechanism 200 installed on the gate frame 100 to seal the gap between the gate frame 100 and the steel dam gate 110; the water-stopping mechanism 200 includes water-blocking vertical plates 210 symmetrically arranged on the gate frame 100, a water-blocking horizontal plate 211 fixedly connected to one side of the two water-blocking vertical plates 210 at a lower position, and a sealing strip 212 fixedly connected to the water-blocking vertical plates 210 and the water-blocking horizontal plate 211 on the same side.

[0030] like Figure 2 As shown, the water-blocking vertical plate 210 is triangularly arranged, and the water-blocking horizontal plate 211 is fixedly connected to a water-guiding slope 213 on the side away from the sealing strip 212. In this embodiment, the triangular arrangement of the water-blocking vertical plate 210 guides the water flow and reduces the impact of the water flow on the sealing strip 212. The hydraulic drive device 111 is activated, which drives the steel dam gate 110 to move towards the water-blocking horizontal plate 211, so that the steel dam gate 110 squeezes the sealing strip 212, causing the sealing strip 212 to deform, thereby forming a seal between the water-blocking vertical plate 210, the water-blocking horizontal plate 211 and the steel dam gate 110.

[0031] It should be noted that the hydraulic drive device 111 includes a hydraulic telescopic rod and a connecting seat. The hydraulic telescopic rod drives the connecting seat installed on the steel dam gate 110 to move, thereby causing the steel dam gate 110 to flip and intercept or release water.

[0032] like Figure 3 As shown, the sealing strip 212 is a corrosion-resistant sealing strip, and multiple sealing strips 212 are set on the side of the water-blocking vertical plate 210 and the water-blocking horizontal plate 211 near the steel dam gate 110.

[0033] In this embodiment, the sealing strip 212 is made of EPDM rubber, which has excellent weather resistance, aging resistance, abrasion resistance, compression set resistance, and low-temperature flexibility. When the gate is closed in place, the sealing strip 212 must reach the designed compression amount to ensure a seal without over-compression that could lead to premature failure.

[0034] like Figure 1 and Figure 4 As shown, a sealing mechanism 300 is provided on the gate frame 100. The sealing mechanism 300 includes a sealing air-filled pad 313 installed on the gate frame 100. An air compressor 310 and an air tank 311 are fixedly installed on the gate frame 100, and the air tank 311 is connected to the sealing air-filled pad 313. The air compressor 310 is connected to the air tank 311, and a pressure gauge is provided on the air tank 311. An exhaust pipe is provided on the sealing air-filled pad 313, and an electric valve is provided on the exhaust pipe.

[0035] In this embodiment, air is introduced into the air storage tank 311 by the air compressor 310, compressing the air into high-pressure gas. After the steel dam gate 110 is closed, the high-pressure gas in the air storage tank 311 fills the sealing air pad 313, causing the sealing air pad 313 to expand and seal the gap between the steel dam gate 110 and the gate frame 100, preventing water leakage. When the steel dam gate 110 is opened, the electric valve opens, the gas in the sealing air pad 313 is discharged, and the sealing air pad 313 contracts, preventing it from affecting the opening of the steel dam gate 110.

[0036] It should be noted that once the pressure inside the air tank 311 reaches the set value, the air compressor 310 stops working. The air tank 311 allows for rapid inflation of the sealing air pad 313, achieving a quick seal. The sealing air pad 313 is made of Kevlar fiber reinforced air, which has strong fatigue resistance and corrosion resistance.

[0037] like Figure 4 As shown, the gate frame 100 has limiting grooves 312 on its side wall and bottom corresponding to the sealing air pad 313, and the steel dam gate 110 also has limiting grooves 312 on its side wall and bottom. The sealing air pad 313 is a corrosion-resistant air pad, and the sealing air pad 313 has the same shape as the sealing strip 212.

[0038] In this embodiment, a limiting groove 312 is provided to limit the sealing air pad 313, so that the sealing air pad 313 expands within a limited space to seal the limiting groove 312, thereby preventing water leakage and improving the sealing performance.

[0039] Working principle: The hydraulic drive device 111 drives the steel dam gate 110 to rotate, thereby moving the steel dam gate 110 closer to the water-blocking vertical plate 210 and water-blocking horizontal plate 211. Ultimately, the steel dam gate 110 is squeezed against the sealing strip 212, thereby maintaining a seal between the steel dam gate 110 and the gate frame 100 and intercepting the water flow. High-pressure gas is injected into the sealing air pad 313 through the air storage tank 311, causing the sealing air pad 313 to expand and seal the limiting groove 312, further improving the sealing performance between the gate frame 100 and the steel dam gate 110.

[0040] It should be noted that the air compressor 310, air tank 311, sealing strip 212, and sealing air pad 313 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the air compressor 310 is powered by AC mains power, which will not be elaborated here.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
