Description

Technical Field

[0001] This utility model relates to the field of gate technology, and in particular to a hydraulically topped bidirectional water-stopping gate. Background Technology

[0002] Currently, stainless steel gates are commonly used to stop water flow at the inlet and outlet of water supply and drainage, sewage treatment, pumping stations, and canal irrigation projects. Among them, the horizontal pull-type steel flat gate is widely used. It is equipped with an integrated hydraulic hoist. Its core function is to block lake water from entering the culvert during non-rainy periods, and to open the gate when the rainy season arrives and the lake water level rises to complete flood control and drainage operations and ensure the safety of the project area.

[0003] Existing gates suffer from significant leakage problems in practical applications. The sealing structure design of traditional gates is not perfect, and the seal between the gate plate and the base is insufficient. Under the pressure of water flow, gaps are prone to leakage, which not only affects the water-stopping effect but may also have adverse effects on engineering equipment and the surrounding environment, reducing the reliability and practicality of the gate in various projects. Although sealing gaskets are often used to enhance the sealing performance, the sealing gaskets are prone to fatigue damage after repeated compression and release, affecting the sealing performance and making it difficult to meet the requirements of high-precision water-stopping. Based on this, a hydraulic top-mounted bidirectional water-stopping gate is proposed. Utility Model Content

[0004] This utility model proposes a hydraulically topped bidirectional water-stop gate to solve the problem of insufficient sealing between the existing gate plate and the base, and the easy fatigue and damage of the sealing gasket, which leads to easy leakage under water pressure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulically top-mounted bidirectional water-stop gate, comprising a base, with uprights fixed at both ends of the upper surface of the base, and a liftable gate plate between the two uprights, and further comprising: A groove is formed along the length direction on the upper end face of the base, and the bottom end of the gate can be embedded in the groove; The inflation / deflation assembly includes a follower piston and two airbag tubes, which are symmetrically arranged on both sides inside the groove. When the gate rises, it drives the piston to move, thereby releasing the gas in the airbag tubes.

[0006] Preferably, side plates are fixed on both sides of the gate, and a top plate is fixed on the top of the side plates. A lifting hydraulic cylinder is installed inside the upright frame, and the top of the lifting hydraulic cylinder is installed on the top plate.

[0007] Preferably, the piston component includes a piston cylinder installed at the bottom of the inside of the upright, and a piston is provided inside the piston cylinder. A telescopic rod is connected to the upper end face of the piston, and the top end of the telescopic rod is connected to the bottom end of the side plate.

[0008] Preferably, the piston component further includes a slot formed in the base, and the bottom end of the piston is connected to the piston by a through connecting pipe.

[0009] Preferably, it also includes an L-shaped scraper, which is fixed to the lower end of the outer wall of the gate, and the scraping surface of the L-shaped scraper is in contact with the upright.

[0010] Preferably, the gate includes a carbon fiber reinforced composite layer on the outer side, and a metal core layer is provided on the inner side of the carbon fiber reinforced composite layer.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: (1) This utility model uses a groove in the base and symmetrically arranged airbag tubes to realize the automatic inflation and deflation of the airbag tubes by using the gate lifting linkage inflation and deflation component. When the gate is closed, the airbag tubes are inflated and tightly fill the gap between the bottom of the gate and the groove, forming a double sealing structure, which effectively solves the water leakage problem of the existing gate and improves the reliability of bidirectional water stop.

[0012] (2) The inflation / deflation assembly and the gate's lifting and lowering actions are synchronized, eliminating the need for an additional drive device. The inflation / deflation process of the airbag tube can be completed by the gate's own lifting and lowering, simplifying the operation process and reducing the energy consumption of the equipment. At the same time, the airbag tube automatically deflates when the gate is opened, and the water flow can flush the groove area, reducing the accumulation of impurities and lowering maintenance costs.

[0013] (3) The gate adopts a composite structure of carbon fiber reinforced composite layer and metal core layer. The carbon fiber reinforced composite layer improves the surface wear resistance and corrosion resistance, ensuring sealing reliability. The metal core layer enhances the structural rigidity and deformation resistance of the gate, enabling it to withstand high pressure and high frequency opening and closing conditions and extend its service life.

[0016] 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.

[0017] like Figures 1-7As shown, this utility model provides a hydraulically topped bidirectional water-stop gate, including a base 1. The base 1 is made of high-strength concrete or forged alloy steel, possessing impact resistance and settlement resistance, and can be directly fixed to the concrete base of the gate well or channel. Uprights 2 are fixed to both ends of the upper surface of the base 1, and a liftable gate plate 3 is provided between the two uprights 2. Side plates 6 are fixed to both sides of the gate plate 3, and a top plate 7 is fixed to the top of the side plates 6. A lifting hydraulic cylinder 5 is installed inside the uprights 2. The side plates 6 and the guide rails inside the uprights 2 form a sliding fit, which can constrain the lifting and lowering of the gate plate 3, preventing it from shifting under the impact of water flow. The top of the lifting hydraulic cylinder 5 is installed on the top plate 7, and the lifting and lowering of the top plate 7 can be achieved by the lifting hydraulic cylinder 5, thereby adjusting the gate plate 3 by driving the side plates 6 to lift and lower. The drainage capacity includes a groove 101 formed along the length of the upper surface of the base 1, into which the bottom end of the gate 3 can be embedded. It also includes an inflation / deflation assembly 8, which comprises a follower piston and two airbag tubes 85. The two airbag tubes 85 are symmetrically arranged on both sides inside the groove 101. Specifically, the airbag tubes 85 are embedded inside the groove 101. After inflation, the airbag tubes 85 fit snugly against the bottom end of the gate 3, improving the sealing of the bottom end of the gate 3 within the groove 101 and preventing leakage. When the gate 3 rises, it drives the piston to release the gas in the airbag tubes 85. When the gate 3 falls, it drives the piston to send the gas in the piston into the airbag tubes 85, causing the airbag tubes 85 to inflate and fill the gap between the bottom end of the gate 3 and the groove 101.

[0018] Among them, see Figures 3-6 As shown, the piston assembly includes a piston cylinder 81, which is installed at the bottom of the inside of the stand 2. The piston cylinder 81 is equipped with a piston 86. The upper end of the piston 86 is connected to a telescopic rod 82. The telescopic rod 82 is a multi-section telescopic structure. The top end of the telescopic rod 82 is connected to the bottom end of the side plate 6. The piston assembly also includes a slot 83 opened in the base 1. The bottom end of the piston 86 is connected to the piston 86 by a through connecting pipe 84. The end of the airbag tube 85 is connected to the slot 83 by a connecting pipe.

[0019] As described above, in practical use, the lifting hydraulic cylinder 5 is used to raise and lower the gate plate 3, thereby opening and closing the gate. When the gate switches from the open state to the closed state, that is, during the descent of the gate plate 3, the gate plate 3 will simultaneously push the telescopic rod 82 downward. Since the telescopic rod 82 adopts a multi-section telescopic structure, it can stably transmit downward pressure, thereby pushing the piston 86 to move downward in the piston cylinder 81. During this process, the piston 86 will compress the air inside the piston cylinder 81, so that the air is forced into the empty groove 83 in the base 1 through the connecting pipe 84, and then transported to the airbag tube 85 through the connecting pipe. As the gate plate 3 continues to move downward, the piston 86 continuously compresses the air until the gate plate 3 moves to the bottom. At this point, the airbag tube 85 is filled with air and reaches its maximum inflated state, thereby tightly fitting the contact surface between the bottom of the gate plate 3 and the base 1, effectively achieving a seal between the two and preventing water leakage.

[0020] When the gate switches from the closed state to the open state, that is, during the process of the gate plate 3 rising, the gate plate 3 will drive the telescopic rod 82 to move upward, which in turn pulls the piston 86 to move upward in the piston cylinder 81. At this time, a negative pressure is formed inside the piston cylinder 81, which will draw air from the empty groove 83 through the connecting pipe, and then further draw it into the piston cylinder 81 through the connecting pipe 84. At the same time, the air in the airbag tube 85 will also be gradually drawn back. As the gate plate 3 continues to move upward, the airbag tube 85 gradually collapses, and the groove 101 originally covered by the airbag tube 85 is fully opened, so that the water flow can pass smoothly and flush the groove 101 and the surrounding area, reducing the accumulation of impurities.

[0021] This design controls the inflation and deflation of the airbag tube 85 through the lifting and lowering action of the gate 3, which not only ensures the sealing performance when the gate is closed, but also enables self-cleaning with the help of water flow when it is opened, thus improving the practicality and durability of the gate.

[0022] In addition, see Figures 1-2 As shown, it also includes an L-shaped scraper 4, which is fixed to the lower end of the outer wall of the gate plate 3. The scraping surface of the L-shaped scraper 4 is in contact with the support frame 2. When the gate plate 3 is raised or lowered, the L-shaped scraper 4 can also move synchronously. The L-shaped scraper 4 can continuously scrape the area on the support frame 2 near the gate plate 3, thereby removing scale, mud and other impurities attached to the area in time, avoiding the accumulation of impurities in the gap between the support frame 2 and the gate plate 3, and reducing the corrosion and wear caused by long-term attachment of impurities to the equipment.

[0023] Additionally, see Figure 7As shown, the gate 3 includes a carbon fiber reinforced composite layer 31 on the outer side and a metal core layer 32 on the inner side of the carbon fiber reinforced composite layer 31. The carbon fiber reinforced composite layer 31 is formed by molding or winding carbon fiber and resin matrix (such as epoxy resin, phenolic resin, etc.), and has high strength, low friction coefficient and excellent wear resistance and corrosion resistance, which can effectively improve the surface sealing reliability and service life of the gate 3. The metal core layer 32 is made of high-strength alloy material (such as stainless steel, titanium alloy, etc.) and is firmly bonded to the carbon fiber reinforced composite layer 31 by mechanical connection or bonding, which can provide stable structural support for the gate 3 and ensure its structural rigidity and deformation resistance under high pressure and high frequency opening and closing conditions.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
