Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction, and in particular to a water conservancy gate for opening and closing. Background Technology

[0002] Existing hydraulic gates typically only have a single opening and closing function, relying on the raising and lowering of the gate plate to control water flow. However, in actual operation, because water often contains floating impurities or suspended particles, these impurities tend to accumulate at the bottom of the gate when it is lowered to close, affecting the complete fit and seal of the gate plate and causing leakage or difficulty in opening and closing. To address this, some devices incorporate a filter screen at the front of the gate to block impurities. However, this type of filter structure operates independently of the gate's opening and closing actions, making synchronous operation impossible. As a result, when the gate is opened to release water, impurities are easily carried by the water flow and impact the filter components, causing blockages, affecting water flow efficiency, and increasing cleaning and maintenance workload. Utility Model Content

[0003] The purpose of this utility model is to solve the problem of inconvenience in the independent control and use of traditional gates, filters and sluices, and to propose a hydraulic gate for opening and closing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic gate, comprising a frame erected within a water channel, a sluice gate vertically limited and slidable within the frame, a filter gate offset and slidable in the opposite direction to one side of the sluice gate, a lifting assembly for controlling the raising and lowering of the sluice gate installed on the frame, and a steel wire rope sliding on the frame being fixed together at the top of the sluice gate and the top of the filter gate. The frame includes a crossbeam and columns fixed at both ends, with the filter gate and sluice gate sliding alternately and in opposite directions between the two columns.

[0005] As a further description of the above technical solution: the frame also includes end plates that are connected to the columns at right angles at both ends, and two pairs of angle irons are fixed to the opposite faces of the two columns, and multiple expansion screws for fixing are provided on the columns.

[0006] As a further description of the above technical solution: the filter door includes a slide that is attached to one side of the two columns and is in contact with them under water pressure. A mesh plate is fixed on one side of the slide, and a lifting hole for fixing the end of the steel wire rope is provided on the slide.

[0007] As a further description of the above technical solution: the sluice gate includes a gate plate that slides vertically between two pairs of angle irons on both sides, and a transition seat is fixed on the top of the gate plate. The transition seat has an opening for fixing one end of a steel wire rope.

[0008] As a further description of the above technical solution: the lifting assembly includes a bearing seat fixed to the inner wall of the crossbeam, a threaded sleeve is rotatably installed on the bearing seat, a screw is threaded into the threaded sleeve, and the bottom end of the screw is fixed to the adapter seat.

[0009] As a further description of the above technical solution: the mesh plate is arc-shaped, and the bottom of the mesh plate is blocked and the top is open.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This solution utilizes a reverse linkage structure between the sluice gate and the filter gate to achieve synchronous control of gate opening and closing and impurity filtration. In the closed state, the filter gate rises to form a bottom seal and top overflow filtration, preventing floating impurities in the water from accumulating at the bottom of the gate, thus ensuring stable gate sealing performance. In the open state, the filter gate rises and falls in the opposite direction with the sluice gate, and the arc-shaped mesh plate filters the flowing water, effectively preventing large particles of impurities from entering the downstream water area, reducing the risk of blockage, achieving both smooth opening and closing and water purification, and improving the safety and reliability of overall water conservancy regulation.

[0013] 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.

[0014] like Figure 1 - Figure 4 As shown, the present invention provides a hydraulic gate, including a frame 1 erected in a water channel, a sluice gate 3 vertically limited and slidable inside the frame 1, a filter gate 4 offset and slidable in the opposite direction to the sluice gate 3 on one side, a lifting assembly 2 for controlling the lifting of the sluice gate 3 installed on the frame 1, and a steel wire rope that slides on the frame 1 is fixed together with the top of the sluice gate 3 and the top of the filter gate 4. In use, this solution involves rotating the screw sleeve 23, which causes the screw 22 to move up and down. During this movement, the screw 22 slides the bottom gate 31 between the two pairs of angle irons 14 on both sides, thus controlling the flow of the water gate 3. When the water gate 3 is closed and descending, the steel wire pulls the filter gate 4 upward, creating a bottom-sealed and top-overflow filtering effect. When the gate is opened to release water, the screw 22 causes the adapter 32 and the gate 31 to rise, while the filter gate 4 descends simultaneously. At this time, the arc-shaped mesh plate 42 filters impurities and prevents clogging, achieving bottom-filtered water release.

[0015] The frame 1 includes a crossbeam 11 and columns 13 fixed at both ends, and the filter gate 4 and the sluice gate 3 slide alternately and in opposite directions between the two columns 13.

[0016] Specifically, such as Figure 4 As shown, the frame 1 also includes end plates 12 that are connected at right angles to the columns 13 at both ends. Two pairs of angle irons 14 are fixed to the opposite sides of the two columns 13. Multiple expansion screws 15 for fixing are provided on the columns 13.

[0017] The frame 1 structure forms a stable rectangular load-bearing frame 1 through the right-angle connection between the end plate 12 and the column 13, giving the entire gate system high structural rigidity and resistance to deformation when installed in the water channel. Two pairs of diagonal irons 14 fixed to the inner side of the column 13 provide precise vertical sliding guidance for the gate plate 31, ensuring uniform force distribution and smooth movement during the raising and lowering of the gate 3, and preventing jamming or poor sealing of the gate plate 31 due to guide deviation. Expansion bolts 15 on the column 13 are used to firmly anchor the frame 1 to the channel wall or base, enhancing overall impact resistance and durability, thereby ensuring that the gate maintains stable and reliable opening and closing performance even under prolonged water pressure.

[0018] Specifically, such as Figure 2 As shown, the filter door 4 includes a slide 41 that is attached to one side of the two columns 13 and is attached to them by water pressure. A mesh plate 42 is fixed on one side of the slide 41, and a lifting hole 43 for fixing the end of the steel wire rope is provided on the slide 41.

[0019] The filter gate 4 is guided and supported by a slide 41 attached to one side of the column 13, ensuring a stable fit under water flow and preventing structural deformation or displacement due to water pressure. The mesh plate 42 fixed on the slide 41 performs primary filtration of the flowing water, intercepting impurities while maintaining smooth water flow, thus preventing blockage in the gate area. The lifting holes 43 on the slide 41 are used to fix the ends of the steel wire rope, enabling the filter gate 4 to form a reverse linkage with the sluice gate 3. When the sluice gate 3 descends, it lifts the filter gate 4; when the sluice gate 3 ascends, it lowers the filter gate 4, thus achieving dynamic switching between bottom sealing and top filtration. This design ensures that the filter gate 4 maintains uniform force and synchronized operation during filtration and opening / closing control, significantly improving the overall coordination and anti-clogging performance of the gate system.

[0020] Specifically, such as Figure 2 As shown, the sluice gate 3 includes a gate plate 31 that slides vertically between two pairs of angle irons 14 on both sides. A transition seat 32 is fixed on the top of the gate plate 31, and an opening is provided on the transition seat 32 for fixing one end of a steel wire rope.

[0021] The sluice gate 3 structure uses the limiting fit between the gate plate 31 and two pairs of angle irons 14 on both sides to maintain the stability of the gate plate 31 when sliding in the vertical direction, preventing deviation or shaking during operation, thus ensuring the tightness of the gate opening and closing. The adapter seat 32 set on the top of the gate plate 31 serves as a connection and force transmission, and the wire rope fixing hole on it facilitates linkage with the lifting assembly 2. When the wire rope is driven, it can directly drive the gate plate 31 to rise and fall, realizing the control of water flow. This design makes the transmission link of the sluice gate 3 simple and the force transmission path clear, which helps to reduce mechanical wear and improve the gate opening and closing response speed and the overall structural reliability and stability.

[0022] Specifically, such as Figure 2 As shown, the lifting assembly 2 includes a bearing seat 21 fixed to the inner wall of the crossbeam 11. A threaded sleeve 23 is rotatably mounted on the bearing seat 21. A screw 22 is threadedly fitted onto the threaded sleeve 23. The bottom end of the screw 22 is fixed to the adapter 32.

[0023] The lifting assembly 2 achieves precise raising and lowering control of the gate through the threaded engagement of the screw sleeve 23 and the screw rod 22. The screw sleeve 23 can rotate stably within the bearing seat 21, thereby converting the rotational motion into the linear raising and lowering motion of the screw rod 22. The bottom end of the screw rod 22 is fixed to the adapter seat 32, so that it can synchronously drive the sluice gate 3 to rise or fall during the raising and lowering process, ensuring that the gate plate 31 slides vertically stably and is evenly stressed, avoiding jamming or wear caused by uneven loading. This structure not only improves the smoothness and controllability of the gate opening and closing, but also allows for fine-tuning control by changing the rotation angle of the screw rod 22, meeting the precise adjustment needs under different water level conditions, and improving the mechanical reliability and service life of the device.

[0024] Specifically, such as Figure 3 As shown, the mesh plate 42 is arc-shaped, with a blocked bottom and an open top.

[0025] The arc-shaped mesh plate 42, with its bottom sealing and top opening structure, allows the filter door 4 to form a water flow guide path that directs debris to both sides during operation. When the water passes through the arc-shaped surface, it generates a diversion effect, slows down the flow rate, and causes the impurities to disperse to both sides along the arc, thereby preventing the impurities from accumulating and clogging the filtration area. Furthermore, the resistance of the impurities directly acts on the columns 13 on both sides, greatly reducing the resistance they experience.

[0026] In actual water conservancy regulation scenarios, when the gate 31 is opened, the screw 22 drives the gate 31 to rise through the lifting assembly 2, while the wire rope drives the filter gate 4 to move downward. The arc-shaped mesh plate 42 of the filter gate 4 forms a primary filtration surface in the water flow, intercepting floating objects and suspended particles in the upper layer, while the bottom opening keeps the water flow unobstructed, allowing the water to be smoothly discharged into the downstream area, thus achieving water purification while opening the gate to release water. As the water level gradually drops, the gate 31 can slowly move downward according to control requirements, while the filter gate 4 moves upward simultaneously. The bottom sealing structure blocks the water flow from directly impacting the bottom of the gate, while the top opening still maintains overflow, so that the water forms a top-down filtration path, which not only prevents sediment accumulation, but also maintains the coexistence of bottom sealing and top overflow when the water level is stable, ensuring a relatively constant water level. This coordinated action enables the gate system to seamlessly switch between flow regulation and filtration functions under different water level conditions, avoiding the accumulation of impurities, failure of the gate 31 seal, or difficulty in opening and closing. At the same time, it effectively protects the ecological environment of downstream waters during the flood season or water diversion process, and improves the safety, reliability, and ease of maintenance of the entire water conservancy facility.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
