Description

Technical Field

[0001] This utility model relates to the field of water conservancy control equipment technology, and in particular to a water-stopping, zero-leakage rotating weir. Background Technology

[0002] In existing water conservancy projects or urban flood control systems, adjustable weirs or gates are commonly used to control the inflow and outflow of water into channels or reservoirs. However, traditional weir structures generally suffer from the following problems: First, most weirs use flat-plate or curved-plate weirs, whose sealing parts typically rely on a single-point rubber strip compression to form a line contact seal. During long-term operation, due to rubber aging, installation misalignment, or water pressure impact, leaks or minor water leakage are highly likely to occur, affecting not only the accuracy of water level control but also potentially causing damage to downstream equipment.

[0003] Secondly, existing weir gates mostly employ rigid connections or single-sided drive methods. When the weir gate opens and closes under water pressure, uneven force distribution can easily lead to panel deformation or localized jamming, affecting the stability and service life of the weir gate. Although some devices are equipped with hydraulic drive systems, unreasonable cylinder placement or hinge structures result in uneven torque distribution during movement, leading to high opening and closing resistance and a limited adjustment angle range. Therefore, designing a zero-leakage rotating weir is essential. Utility Model Content

[0004] The purpose of this invention is to provide a water-stopping, zero-leakage rotating weir to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a zero-leakage rotating weir, comprising a panel, a hinge, a side plate, a base plate, a water-stop plate, a water-stop rubber, a hydraulic cylinder, and a hydraulic cylinder hinge; the panel is disposed on the front of the weir body, and its two ends are movably connected to the side plate through the hinge; the side plate is fixedly installed on the base plate to support both sides of the rotating weir gate; one end of the panel is fixedly connected to the water-stop plate, and a water-stop rubber is installed on the outer edge of the water-stop plate, the water-stop rubber being sealed to the base plate; the bottom end of the hydraulic cylinder is hinged to the side plate through a hydraulic cylinder hinge, and the piston rod end of the hydraulic cylinder is hinged to the middle of the panel; the hydraulic cylinder drives the panel to rotate around the hinge through extension and retraction to realize the opening and closing of the weir gate, and can stop at any angle position to control the upstream water level.

[0006] According to the above technical solution, the hinge chain adopts a pin connection structure, which enables the panel to rotate around the hinge axis.

[0007] According to the above technical solution, the water-stopping rubber is made of flexible rubber material, which forms an elastic sealing fit with the foundation plate when the weir gate is closed.

[0008] According to the above technical solution, the hydraulic cylinder hinge has a double-ear structure and is connected to the bottom end of the hydraulic cylinder by a pin.

[0009] According to the above technical solution, the side plate is fixedly connected to the base plate to ensure the overall stability and sealing of the weir structure.

[0010] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: This utility model, through the coordinated structure of a panel, a support hinge, a side plate, a base plate, a waterstop plate, a waterstop rubber, a hydraulic cylinder, and a hydraulic cylinder hinge, enables the weir gate to open and close smoothly under water pressure. The waterstop rubber installed on the outer edge of the waterstop plate forms a multi-point elastic seal with the base plate, achieving a zero-leakage waterstop effect when the weir gate is closed, effectively improving sealing reliability. The hydraulic cylinder drives the panel to rotate around the support hinge via extension and retraction, and can stop at any angle, allowing the weir gate opening angle to be continuously adjustable, thereby achieving precise control of the upstream water level. This structure not only has excellent waterstop performance and smooth opening and closing, but also has a simple overall structure and is easy to maintain, making it suitable for various water conservancy projects and water storage scenarios.

[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] Example: Reference Figure 1-2 This utility model provides a zero-leakage rotating weir, including a panel 1, a support hinge 2, a side plate 3, a base plate 4, a water-stop plate 5, a water-stop rubber 6, a hydraulic cylinder 7, and a hydraulic cylinder hinge 8.

[0015] The panel 1 is located on the front of the weir body to form a water-retaining surface, and its overall structure is a rectangular steel plate. Both ends of the panel 1 are movably connected to the side plates 3 via hinges 2. The hinges 2 employ stainless steel pins and wear-resistant bushings, allowing the panel 1 to rotate around the hinge axis. The side plates 3 are vertically arranged load-bearing structures, fixedly installed on the base plate 4, to support both sides of the rotating weir gate and form the boundary of the water flow channel.

[0016] The base plate 4 is horizontally positioned and serves as the installation reference surface for the entire machine. The base plate 4 is fixedly connected to the side plate 3 to ensure that the weir maintains its overall sealing and structural stability under long-term water pressure.

[0017] A waterstop plate 5 is fixedly connected to one end of panel 1, and a waterstop rubber 6 is installed on the outer edge of the waterstop plate 5. The waterstop rubber 6 is made of flexible rubber, with its outer edge fitting against panel 1 and its bottom edge sealing against the base plate 4. This structure forms a multi-point contact elastic seal when the weir gate is closed, thereby achieving a zero-leakage waterstop effect.

[0018] The hydraulic cylinders 7 are arranged on both sides of the weir gate. The bottom end of the cylinder is fixedly connected to the side plate 3 via a hydraulic cylinder hinge 8, and the end of the cylinder piston rod is hinged to the trunnion in the middle of the panel 1. The extension and retraction of the hydraulic cylinders 7 can drive the panel 1 to rotate around the support hinge 2, thereby opening and closing the weir gate. The hydraulic cylinder hinge 8 has a double-ear structure and is hinged to the cylinder base via a pin, so that the hydraulic cylinder 7 maintains stable rotation during extension and retraction.

[0019] In practical operation, when the water level needs to be raised, the hydraulic system controls the extension of cylinder 7, causing panel 1 to rotate upwards around hinge 2. The waterstop plate 5 and waterstop rubber 6 gradually come into contact with the base plate 4, forming a sealing surface and blocking the upstream water flow. When water needs to be discharged or the water level lowered, cylinder 7 retracts, causing panel 1 to rotate in the opposite direction, allowing water to flow out through the lower part of the weir gate. Because cylinder 7 can stop at any stroke position, the weir gate angle can be continuously adjusted, thus precisely controlling the upstream water level.
