Description
A type of lifting hydraulic steel gate Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a lifting water conservancy steel gate. Background Technology
[0002] Hydraulic gates are mostly installed on important rivers and canals. By controlling the gate's closure (lowering to close) or opening (raising to open), the amount of water accumulating in the river or canal is controlled. Lowering the gate to close can prevent floods, tides, or raise the upstream water level to meet the needs of irrigation, power generation, navigation, aquaculture, environmental protection, industry, and domestic water use. However, during the closing process, existing gates are prone to colliding with the bottom of the gate frame, which can cause damage to the gate or gate frame over time, resulting in high maintenance costs. Furthermore, the lower end of the gate usually needs to be embedded in a groove at the bottom of the gate frame to enhance the sealing after closing. However, when the gate is open, debris in the water can easily accumulate in the groove at the bottom of the gate frame, causing the gate to not close tightly or not at all when closing. At the same time, existing common gates are usually solid structures, making the gates heavy and difficult to open. Summary of the Invention

[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] Referring to Figures 1 to 4, this utility model provides a lifting hydraulic steel gate, comprising: a gate frame 7, a main horizontal plate 3 fixedly connected to the upper surface of the gate frame 7, a rotating cylinder 2 movably connected to the upper surface of the main horizontal plate 3 via a bearing, a main motor 4 fixedly connected to an installation groove on the upper surface of the main horizontal plate 3, and a rotating cylinder 2 screwed to the upper end of a main screw 1, a movable block 8 fixedly connected to the lower end of the main screw 1, the movable block 8 being movably connected to a movable seat 9 via a rotating shaft, and the surfaces of the gate body 12 and the sealing plate 10 being fixedly connected to the lower surface of the movable seat 9 respectively. Simultaneously, the gate body 12 is slidably connected to a sealing groove on the inner side of the gate frame 7, a reinforcing plate 11 is fixedly connected inside the gate body 12, and a symmetrically connected storage cylinder 16 is connected to a sealing groove at the bottom of the gate frame 7. A buffer rod 15 is slidably connected inside the storage cylinder 16 via a main spring, and a buffer plate 13 is fixedly connected to the upper end of the buffer rod 15.
[0019] In this embodiment, when the hydraulic steel gate needs to be closed, the main motor 4 is switched on. The drive wheel, which is fixedly connected to the output shaft of the main motor 4, can drive the rotating cylinder 2 to rotate through the meshing gear ring 5. Then, the rotating cylinder can push the movable block 8, the movable seat 9, and the gate body 12 to move down synchronously through the screwed main screw 1. When the lower end of the gate body 12 is embedded in the sealing groove opened at the bottom of the gate cavity, the gate body 12 can push the buffer plate 13 in the sealing groove to move down. The buffer plate 13 can squeeze the main spring in the receiving cylinder 16 through the buffer rod 15, thereby releasing the bottom of the gate frame 7 cavity. The closed state of the sealing groove enhances the sealing performance between the gate frame 7 and the gate body 12 after closing, and also reduces the degree of collision between the gate frame 7 and the gate body 12 due to closing, reducing the probability of accidental damage to both. Furthermore, after closing, the reinforcing plate 11 installed inside the gate body 12 can enhance the overall structural strength of the hydraulic steel gate, while the structure of the guide plate 14 can help reduce the impact force of water flow on the hydraulic steel gate, and help reduce the probability of deformation and damage to the hydraulic steel gate due to water flow impact, thereby extending the service life of the hydraulic steel gate.
[0020] As a preferred embodiment, the gate frame 7 has a U-shaped structure, the sealing groove opened on the inner side of the gate frame 7 has a U-shaped structure, and two sets of limiting blocks 6 are fixedly connected to the upper ends of both ends of the sealing groove. Both sets of limiting blocks 6 have a square structure, and the main horizontal plate 3 fixedly connected to the upper surface of the gate frame 7 has a rectangular structure. At the same time, the rotating cylinder 2 movably connected in the middle of the main horizontal plate 3 has an I-shaped cylindrical structure.
[0021] In this embodiment, as shown in Figures 1 and 2, the setting of the limiting block 6 can effectively limit the movement range of the hydraulic steel gate, thereby preventing the movable seat 9 and the movable block 8 from hitting the main horizontal plate 3, and reducing the probability of accidental damage to the hydraulic steel gate during the opening process.
[0022] In a preferred embodiment, two sets of auxiliary blocks are symmetrically connected to the upper surface of the rotating cylinder 2. Both sets of auxiliary blocks have a square outer and round inner shape. The lower end of the outer side of the rotating cylinder 2 is fixedly connected to the gear ring 5, and the gear ring 5 meshes with the drive wheel fixedly connected to the output shaft of the main motor 4.
[0023] In this embodiment, as shown in Figures 1 and 2, the auxiliary block enables the hydraulic steel gate to be opened automatically by the main motor 4 or manually by workers, thereby improving the fault tolerance of the hydraulic steel gate in emergency situations. Furthermore, the braking component on the surface of the main motor 4 can prevent the output shaft of the main motor 4 from rotating unexpectedly.
[0024] As a preferred embodiment, the gate body 12 is integrally rectangular in structure. The size of the outer side surface of the gate body 12 is adapted to the sealing groove of the gate frame 7. The end surface of the gate body 12 is in a U-shaped structure. At the same time, the sealing plate 10 fixedly connected to the edge of the inner cavity of the gate body 12 is in a C-shaped structure. Along the horizontal direction, a plurality of guide plates 14 are fixedly connected to the water-facing surface of the gate body 12 at equal intervals in parallel. And the plurality of guide plates 14 are all in a long strip structure. The end surface of the guide plate 14 is in a fan-shaped ring structure.
[0025] In this embodiment, as shown in FIGS. 2 and 3, the setting of the sealing plate 10 can ensure that a closed space can be formed inside the gate body 12, thereby avoiding water inflow, assisting in reducing the overall weight of the hydraulic steel gate, reducing the difficulty of opening the gate, and improving the opening efficiency. At the same time, the setting of the guide plates 14 can assist in weakening the impact force of the water flow on the surface of the gate body 12, and reducing the probability of deformation and damage of the gate body 12 due to long-term impact of the water flow.
[0026] As a preferred embodiment, a plurality of reinforcing plates 11 are fixedly connected to the top of the inner cavity of the sealing plate 10 at equal intervals in parallel along the length direction. And the plurality of reinforcing plates 11 are all in a cross-shaped structure. The thickness of the reinforcing plate 11 is equal to the width of the inner cavity of the gate body 12. At the same time, the sealing plate 10 and the reinforcing plate 11 together form an E-shaped structure.
[0027] In this embodiment, as shown in FIGS. 1, 2 and 3, the setting of the reinforcing plate 11 can assist in enhancing the structural strength of the inner cavity of the gate body 12, ensuring that the weight of the hydraulic steel gate is reduced on the premise of unchanged structural strength, and reducing the probability of accidental damage of the hydraulic steel gate.
[0028] As a preferred embodiment, a plurality of through holes are opened in the sealing groove at the bottom of the gate frame 7 at equal intervals in parallel along the length direction. A receiving cylinder 16 is fixedly connected to each through hole. And the receiving cylinder 16 is in a cylindrical structure. The positioning rod 17 fixedly connected to the bottom of the inner cavity of the receiving cylinder 16 is in a cylindrical structure.
[0029] In this embodiment, as shown in FIGS. 1 and 4, the setting of the positioning rod 17 can effectively limit the moving range of the buffer rod 15, thereby avoiding excessive extrusion of the main spring in the receiving cylinder 16, and prolonging the service life of the main spring.
[0030] As a preferred embodiment, the buffer rod 15 is integrally cylindrical in structure. The axial section of the buffer rod 15 is in a T-shaped structure. The lower end of the buffer rod 15 is adapted to the size of the inner cavity of the receiving cylinder 16. The lower surface of the buffer rod 15 abuts against the main spring. At the same time, the buffer plate 13 is in a long strip structure. The buffer plate 13 is adapted to the size of the sealing groove. The buffer plate 13 and the buffer rod 15 together form an E-shaped structure. And through holes are symmetrically opened on the upper surface of the receiving cylinder 16.
[0031] In this embodiment, as shown in Figures 1 and 4, the symmetrical through holes on the upper surface of the receiving cylinder 16 allow the liquid inside to be automatically discharged when the buffer rod 15 moves down, reducing the difficulty of the buffer rod 15 moving down. In addition, the symmetrical notches on the arc surface of the protruding part at the lower end of the buffer rod 15 can help improve the efficiency of liquid discharge. At the same time, the liquid inside the receiving cylinder 16 can also help enhance the buffering effect between the receiving cylinder 16 and the buffer rod 15, reducing the probability of damage to the gate body 12 and the gate frame 7 due to collision.
