[0019] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0020] The applicant argues that before the sluice gates are opened, additional cleaning tools, such as cleaning boats, robotic arms, or manual labor using nets or hooks, are typically used to regularly remove floating debris, resulting in high cleaning frequency and high manpower and material costs.

[0021] To this end, the applicant designed a lifting gate for water conservancy projects. A collection unit that can be raised and lowered with the gate and adjusted for secondary lifting is installed on the water-facing side of the gate plate 2. The working height can be flexibly adjusted according to the water level, which facilitates the collection of floating objects in front of the gate plate 2. When the gate is not open, the collected objects can be processed regularly, reducing the frequency of collection using tools and equipment. In addition, when the wind and waves are large, the collection unit is directly subjected to impact and buffers the force.

[0022] This utility model relates to a lifting gate for water conservancy projects, mainly comprising a lifting frame 1, a gate plate 2 that rises and falls within the lifting frame 1, and a collection unit disposed on the water-facing side of the gate plate 2. A first lifting drive 3 is provided at the top of the lifting frame 1, connected to the top of the gate plate 2, suitable for driving the gate plate 2 to rise and fall along the lifting frame 1. The collection unit is connected to a second lifting drive 4. After the collection unit rises and falls with the gate plate 2, its operating position can be adjusted for secondary operations, allowing for corresponding collection work on the water-facing side. After collection, the second lifting drive 4 can be used to raise the collection unit at any time to process the collected floating debris, and then lower it back to the corresponding operating position. Therefore, the second lifting drive 4 can adjust the operating height of the collection unit according to the water level.

[0023] In some preferred embodiments, an upper plate 5 is configured at a predetermined height on the water-facing side of the gate 2. A second lifting drive 4 is mounted on the upper plate 5, with its driving end located below the upper plate 5 and connected to a mounting plate 6. The collection unit is configured at the bottom of the mounting plate 6. The second lifting drive 4 can be a set of telescopic push rods, which can be connected to a hydraulic working system, etc. The hydraulic working system can be configured on the support beam 13. Simultaneously, the two telescopic push rods can be synchronously controlled by corresponding controllers. The control method and power system are existing technologies and will not be elaborated in this application.

[0024] Specifically, in this embodiment, the collection unit includes a collection frame 7, the rear sidewall of the collection frame 7 has a predetermined working height, and the top of the rear sidewall is fixedly disposed at the bottom of the mounting plate 6.

[0025] The top and front of the collection frame are open, and the front end is extended outward. The bottom wall of the collection frame 7 is a grid plate, and a sieve plate 8 is provided on the grid plate.

[0026] In this embodiment, preferably, multiple sets of rotating rollers 9 are arranged on the rear side wall of the collecting frame 7. The multiple sets of rotating rollers 9 can roll up and down along the water-facing surface of the gate 2 as the collecting frame 7 rises and falls. A pair of mounting vertical plates 10 are arranged on the rear side of the collecting frame 7, and the rotating rollers 9 are rotatably arranged between the mounting plates 6 and spaced vertically.

[0027] It should be noted that the main body of the rotating roller 9 can be made of rubber. The rotating roller 9 includes a rubber roller and an elastic shell disposed on the outer side of the rubber roller. The space between the inner wall of the elastic shell and the outer wall of the rubber roller is filled with an elastic material such as polyurethane or sponge. The elastic shell is also made of rubber, similar to the material used in common ball bearings and anti-collision airbags. When the wind and waves are large, the rear wall of the collecting frame 7 blocks the front side of the gate 2. Multiple sets of rotating rollers 9 are located between the rear side of the collecting frame 7 and the gate 2 to relieve force and buffer, thereby protecting the gate 2 and reducing the deformation of the gate 2.

[0028] In some preferred embodiments, the working surface of the lifting frame 1 is provided with a limiting groove 11, and the two sides of the gate plate 2 are slidably adapted to the corresponding limiting groove 11. The gate plate 2 is provided with rollers 12 at both ends of the upper part of the front and rear side walls. The rollers 12 can roll along the side wall of the limiting groove 11 as the gate plate 2 rises and falls, increasing the contact points during the rising and falling on both sides of the sliding groove, making the rising and falling of the gate plate 2 more stable.

[0029] In this embodiment, preferably, a support beam 13 is configured at the top of the lifting frame 1 via a frame 14, and the first lifting drive 3 is configured on the support beam 13. The first lifting drive 3 includes a winch, which is connected to the top of the gate via a rope. The winch driving the gate to lift is prior art and will not be elaborated on in detail in this embodiment.

[0030] In practical use, when the gate 2 is closed, the working height of the collection frame 7 can be adjusted according to the water level using the telescopic push rod to facilitate the collection of floating debris. The collected floating debris can be periodically lifted using the telescopic push rod and then collected for further processing.

[0031] In addition, when the wind and waves are large, the height of the collection frame 7 can be controlled by the telescopic push rod. The rear plate of the collection frame 7 is blocked on the front side of the gate 2, and appropriate blocking and protection is provided on the water-facing side of the gate 2. Multiple sets of rolling rollers are installed between the water-facing side of the gate 2 and the rear side of the collection frame 7, which play a guiding role when the collection frame is raised and lowered, and play a role in unloading and protecting against strong winds and waves.

[0032] After the gate 2 is opened, it can rise with the gate 2, or it can move down under the drive of the telescopic push rod to adjust the working height of the collection frame 7 and carry out the corresponding collection operation at the gate opening to reduce the floating objects entering the downstream.

[0033] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
