[0017] 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.
[0018] Reference Figures 1 to 4 As shown, this utility model provides a hydraulic water-stopping steel gate for water conservancy projects, including: a gate frame 1, with main sliding grooves 2 symmetrically opened on both sides of the inner cavity of the gate frame 1, and guide grooves 3 opened on the surface of the main sliding grooves 2, a guide plate 5 slidably connected in the guide grooves 3, and a fixed frame 4 slidably connected in the main sliding grooves 2 through the guide plate 5, and gate plates 18 symmetrically connected on both sides of the fixed frame 4, with receiving grooves symmetrically opened at both ends of the surface of the gate plate 18, and through holes symmetrically opened at the bottom of the receiving grooves, one end of a push rod 16 fixedly connected to a fastening plate 12, and the other end of the push rod 16 passing through the through hole. The limiting plate 6 is fixedly connected, and the waterstop 17 is fixedly connected to the side of the main slide 2 relative to the fastening plate 12. At the same time, the reinforcing plate 13 is fixedly connected to the inner cavity of the fixed frame 4. The distribution valve 14 and the hydraulic cylinder 10 are fixedly connected to the surface of the reinforcing plate 13 respectively. The distribution valve 14 is connected to the hydraulic cylinder 10 and the high-pressure electric oil pump 15 respectively through the high-pressure hose 9. The telescopic rod of the hydraulic cylinder 10 is fixedly connected to the moving plate 8, and the two ends of the fixed rod 7 are movably connected to the limiting plate 6 and the moving plate 8 respectively through the bearing seats. The transmission groove 11 is opened on the inner side of the fixed frame 4 relative to the position of the push rod 16.
[0019] In this embodiment, when the water-stop steel gate needs to be lifted, the switch of the high-pressure electric oil pump 15 is activated. The high-pressure electric oil pump 15, through the cooperation of the high-pressure hose 9 and the distribution valve 14, can synchronously control multiple sets of hydraulic cylinders 10. Then, the telescopic rod of the hydraulic cylinder 10 can drive the moving plate 8 to move synchronously. The moving plate 8, through the cooperation of the fixed rod 7 and the limit plate 6, can drive the corresponding push rod 16 and fastening plate 12 to reset, so that the fastening plate 12 and the sealing plate 19 can be separated from the surface of the waterstop 17, releasing the sealing effect between the steel gate and the waterstop 17. Afterwards, when the water-stop steel gate is lifted by the external lifting device (not shown in the figure), the water-stop steel gate will not rub against the waterstop 17, thereby effectively reducing the wear rate of the waterstop 17, extending the service life of the waterstop 17, and ensuring the sealing performance of the hydraulic water-stop steel gate when it is subsequently closed, reducing the probability of safety hazards.
[0020] As a preferred embodiment, the two sets of main sliding grooves 2 opened in the inner cavity of the gate frame 1 are both rectangular in structure, and a set of waterstops 17 are fixedly connected to both sides of the main sliding grooves 2. The end face of the waterstops 17 is P-shaped. Meanwhile, the guide grooves 3 opened on the surface of the main sliding grooves 2 are long strips. The cross section formed by the main sliding grooves 2 and the guide grooves 3 is convex.
[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The waterstop 17 is made of rubber, and its structure helps to enhance its elasticity, thereby enhancing the sealing between the gate plate 18 and the gate frame 1. At the same time, the guide plate 5 and the guide groove 3 are matched in size, which helps to enhance the stability of the steel gate when it moves.
[0022] As a preferred embodiment, the fixing frame 4 has a U-shaped structure. Multiple sets of transmission grooves 11 are opened on both sides of the inner cavity of the fixing frame 4 at equal intervals along the length direction. The transmission grooves 11 have a square structure. The transmission grooves 11 are connected to the storage groove through the through hole. The through hole has a cylindrical structure. At the same time, the storage groove has a long strip structure. The size of the storage groove and the fastening plate 12 are compatible.
[0023] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The opening of the transmission groove 11 enables the hydraulic cylinder 10 to smoothly control the fastening plates 12 on both sides of the steel gate, so that the steel gate and the gate frame 1 can form a double water-stop sealing structure, enhancing the sealing effect of the hydraulic water-stop steel gate.
[0024] In a preferred embodiment, the fastening plate 12 has an elongated shape, and the push rod 16 is connected to the position of the fastening plate 12 relative to the through hole. The push rod 16 has a cylindrical shape, and the side of the fastening plate 12 away from the push rod 16 has an isosceles trapezoidal shape. At the same time, the sealing plate 19 is fixedly connected to the position of the fastening plate 12 relative to the waterstop 17. The sealing plate 19 has an elongated shape.
[0025] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The through hole and the push rod 16 are matched in size, which helps to enhance the stability of the push rod 16 and the fastening plate 12 when they move. The sealing plate 19 can further enhance the sealing performance when the fastening plate 12 and the waterstop 17 come into contact.
[0026] In a preferred embodiment, the reinforcing plate 13 fixedly connected inside the fixed frame 4 has a grid-shaped structure, and the two sides of the reinforcing plate 13 respectively abut against the surface of the gate plate 18 fixedly connected on both sides of the fixed plate. Meanwhile, the sealing layer fixedly connected to the lower surface of the fixed frame 4 has a long strip-shaped structure, and the sealing strip is fixedly connected to the bottom of the inner cavity of the gate frame 1. The cross-section of the sealing strip has a semi-circular structure.
[0027] In this embodiment, as Figure 1 and Figure 2 The reinforcement plate 13 not only enhances the overall structural strength of the hydraulic water-stop steel gate, but also helps to reduce the overall weight of the hydraulic water-stop steel gate, and also helps to fix the hydraulic cylinder 10 and the distribution valve 14. Meanwhile, the sealing layer is made of rubber material, and the sealing strip enhances the sealing effect of the lower surface of the steel gate and the bottom of the inner cavity of the gate frame 1 when the steel gate is closed.
[0028] In a preferred embodiment, the push rod 16 is fixedly connected to a limiting plate 6 at one end within the transmission groove 11. The limiting plate 6 has a square structure and its size is larger than the size of the end face of the push rod 16. Meanwhile, the fixed rod 7, which is movably connected between the limiting plate 6 and the moving plate 8, has a rectangular structure and both ends of the fixed rod 7 have a semi-circular structure.
[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The setting of the limiting plate 6 not only facilitates the connection of the moving plate 8 to the push rod 16 through the fixing rod 7, but also helps to limit the movement range of the push rod 16, thereby preventing the fastening plate 12 and the sealing plate 19 from excessively squeezing the waterstop 17 and reducing the chance of damage to the waterstop 17.
[0030] In a preferred embodiment, a sealing gasket is fixedly connected in the storage groove opened on the surface of the gate plate 18, and the surface of the sealing gasket abuts against the surface of the fastening plate 12. The gate plate 18 has a square structure, and the dimensions of the gate plate 18 and the fixing frame 4 are compatible. Meanwhile, the gate frame 1 has a U-shaped structure.
[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The setting of the sealing gasket can help enhance the sealing performance at the connection between the fastening plate 12 and the gate plate 18. At the same time, the size of the steel gate and the inner cavity of the gate frame 1 are compatible, which can help enhance the effect of the hydraulic water-stop steel gate in water conservancy projects in opening and closing to cut off liquid.
[0032] The hydraulic water-stop steel gate for water conservancy projects of this utility model, through the cooperation of hydraulic cylinder 10, moving plate 8, fixed rod 7, limit plate 6, push rod 16 and fastening plate 12, ensures that the water-stop steel gate does not rub against the water-stop strip 17 during the opening and closing process, thereby extending the service life of the water-stop strip 17 and ensuring the sealing effect of the water-stop steel gate. Moreover, the steel gate and the gate frame 1 can form a double sealing structure to enhance the sealing effect. At the same time, the distribution valve 14 and the high-pressure electric oil pump 15 are both common brand models on the market.
