Description

Technical Field

[0001] This utility model relates to the field of hydraulic protective door technology, specifically to a hydraulic protective door that is easy to adjust the opening and closing angle. Background Technology

[0002] In water conservancy projects, water treatment facilities and other related fields, protective gates are commonly used opening and closing control devices. Their operational stability and practicality directly affect the overall system's operating efficiency. Currently, the mainstream protective gates in China generally adopt a coil-type hoist combined with a wire rope drive opening and closing structure. The gate is opened and closed by pulling the gate leaf lifting lugs with a wire rope. Due to the transmission characteristics of the coil-type hoist, the rotation angle of the protective gate can only be maintained within the range of 0 to 60 degrees, and it is impossible to achieve a larger angle adjustment. This results in limited gate sealing performance and flow control effect. At the same time, the gate cannot achieve a vertical standing state, which affects the space utilization rate. In order to adapt to this opening and closing structure, it is also necessary to build a special machine room, lay tracks, and set up supporting facilities such as machine frame bridge columns. This not only increases the project's land area, but also significantly increases the overall cost of equipment purchase and construction. Therefore, to address the above issues, we propose a hydraulic protective door that is easy to adjust in terms of opening and closing angle. The door is opened and closed by hydraulic drive, and the rotation angle of the door can reach 0 to 180 degrees. When the door is lowered, it can be used as a flat bridge, and when it is upright, it can be used as an arch bridge, which greatly improves the landscape performance and usability of the protective door.

[0008] It should also be noted that the rotation angle of the door leaf can be from 0 to 180 degrees.

[0009] Compared with the prior art, this utility model provides a hydraulic protective door with an easily adjustable opening and closing angle, which has the following beneficial effects: In this utility model, the coordinated use of two gate frames, two gate seat hinge supports, two river-side hinge supports, two hydraulic drive components, and two transmission shafts facilitates stable rotation of the gate leaf, allowing for adjustment of the gate leaf angle from 0 to 180 degrees. When the gate leaf is flat, it can be used as a flat bridge; when the gate leaf is rotated to a vertical position, it can be used as an arch bridge, thereby improving the aesthetic appeal and usability. Furthermore, this hydraulically maneuverable gate, which allows for easy adjustment of the opening and closing angle, is buried underground during installation, resulting in a small footprint, low cost, and aesthetic appeal, making it suitable for use in parks, scenic areas, and other similar locations.

[0013] Please see Figures 1 to 4 A hydraulic safety gate with adjustable opening and closing angle includes a gate frame 1, gate seat hinge supports 2, inter-gate hinge supports 3, a drive shaft 4, gate leaves 5, and a hydraulic drive assembly. Two gate frames 1 and two gate seat hinge supports 2 are installed within two gate frames 1 respectively. Two inter-gate hinge supports 3 are located on either side of the two gate seat hinge supports 2. The drive shaft 4 is rotatably connected between each gate seat hinge support 2 and the adjacent inter-gate hinge support 3. Each gate frame 1 has a through-hole, and each through-hole is fixedly connected to a [missing information - likely a specific component or assembly]. The sealing ring 11 and the two drive shafts 4 are respectively rotatably connected to the two sealing rings 11, which increases the stability and sealing of the drive shafts 4 rotating on the gate frame 1. The gate leaf 5 is connected between the two drive shafts 4. There are two hydraulic drive components, which are respectively installed between the gate leaf 5 and the two gate frames 1. The gate leaf 5 adopts a semi-circular structure. When it is opened and raised, it looks like a human eye, so it is called a protective eye gate. The rotation angle of the gate leaf 5 can reach 0 to 180 degrees. When it is lowered, it can be used as a flat bridge. When it is erected vertically, it can be used as an arch bridge, which greatly improves the landscape performance and the usability.
