Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a gate heightening and water retaining device and a lifting and horizontal gate. Background Art

[0002] The lifting gate, also known as the lifting gate, is a flat gate that moves along an arc track. When closed, the gate leaves stand upright to block water; when opening, the gate leaves first rise along the straight section of the track for a distance, and then move upward and rotate along the arc section of the track (upstream or downstream) until the gate leaves lie flat on the top of the gate pier when fully opened. The working principle of this gate mainly relies on its unique track design and the coordination of the hoist system, which enables the gate leaves to move smoothly on the arc track.

[0003] When the water level rises during the flood season, the gate leaf height cannot meet the use requirements and needs to be raised. Due to the particularity of the lifting and horizontal gate, it is not feasible to simply raise the height of the gate leaf. Because when the gate leaf height is raised, its lifting trajectory will change, and the lifting trajectory may interfere with the hoist machine room above. Therefore, it is also necessary to change the track, gate groove and other structures accordingly. The renovation project is large, difficult to implement, and has low economic benefits. Summary of the invention

[0004] In view of this, the present invention provides a gate heightening water retaining device and a lifting and horizontal gate to solve the problem of large construction workload, difficult implementation and high economic cost in modifying the lifting and horizontal gate to increase the water retaining height.

At the same time, the middle water retaining frame 11 is also the main load-bearing component and needs to withstand the impact of water flow when retaining water. The middle sealing component is mainly used to improve the sealing performance of the middle water retaining component. It is arranged on the end surface and the water-facing side where the middle water retaining frame 11 is connected to the adjacent middle water retaining device 1 or the end water retaining device 2, forming a U-shaped continuous water stop surface, which can prevent water from flowing through the connection between the middle water retaining device 1 and other components, has good sealing performance, and better water retaining effect.

The two first end plates 113 are respectively located at the two ends of the first bottom plate 111, that is, at the two ends of the first panel 112. The bottom surface of the first end plate 113 is connected to the top surface of the first plate body, and its side surface is connected to the second plate body and the first panel 112. And the top surface of the first end plate 113 is flush with the top surface of the first panel 112, and its end surface is flush with the end surfaces of the first bottom plate 111 and the first panel 112. In this embodiment, the shape of the first end plate 113 is similar to a rectangular plate with one corner cut off. Of course, in other embodiments, the first end plate 113 can be other various shapes, such as a triangular plate, a rectangular plate, etc., or can be an irregularly shaped plate.

The first rib 114 can improve the structural strength of the middle water retaining frame 11, and the impact resistance is better. In this embodiment, the first rib 114 has the same shape as the first end plate 113. Of course, in other embodiments, the first rib 114 can also be other shapes, and can be different from the shape of the first rib 114.

[0057] Furthermore, the material of each component in the middle water retaining device 1 is generally metal plate, and the connection method of each component is welding.

[0058] In one embodiment, the middle sealing assembly includes: a first sealing strip 121 and two first sealing members 122. The first sealing strip 121 is arranged at the bottom of the second plate body and is located on the same side as the first panel 112. The two first sealing members 122 are respectively arranged on the two first end plates 113. The first sealing member 122 is arranged along the height direction of the first end plate 113, and has an arc-shaped protrusion 1221 on the side away from the first end plate 113.

[0059] The material of each component of the middle sealing assembly is generally rubber material, and the connection method of each component is adhesive connection. Specifically, the shape of the first sealing strip 121 is long and similar to the shape of the first panel 112. The first sealing strip 121 is arranged at the bottom of the second plate body, directly below the first panel 112, and its outer surface is flush with the surface of the first panel 112. The length of the first sealing strip 121 is equal to the length of the first panel 112, and its bottom surface is in contact with the door leaf 3 to achieve water sealing. The first sealing member 122 includes a long rubber strip body and an arc-shaped protrusion 1221 formed on one side of the rubber strip body. The height of the long rubber strip body is equal to the height of the middle water retaining frame 11, and the long rubber strip body is adhesively connected to the end of the first sealing strip 121.

[0063] The structure of the first end water retaining frame 21 is similar to that of the middle water retaining frame 11, and the main difference is that the overall shape is different. The middle water retaining frame 11 is a straight section frame, while the first end water retaining frame 21 is an L-shaped bent frame. Specifically, the first end water retaining frame 21 includes: a second bottom plate, a second panel, two second end plates and a second rib plate. The second bottom plate and the second panel are both L-shaped, and the second bottom plate also includes two perpendicular plate bodies, the two plate bodies are respectively a third plate body and a fourth plate body, the third plate body can be connected to the door leaf 3, and the top end of the fourth plate body is connected to the bottom end of the second panel. The two second end plates are respectively located at both ends of the second bottom plate, and a plurality of second rib plates are spaced between the two end plates and connected to the second bottom plate and the second panel.

[0064] The second sealing strip 221 is also strip-shaped and is arranged on the water-facing side of the third plate body along the extension direction of the third plate body, that is, the second sealing strip 221 and the second panel are located on the same side. The bottom surface of the second sealing strip 221 contacts the door leaf 3 to achieve water sealing. The first sealing member 122 arranged on the first end water retaining frame 21 has the same structure as the first sealing member 122 arranged on the middle water retaining frame 11, so that the end water retaining device 2 can match the sealing member at the connection of the middle water retaining device 1 to achieve a better water-stopping effect.

The second sealing member 222 is also arranged along the height direction of the first end water retaining frame 21 and has the same height as the first end water retaining frame 21 , but its shape is different from that of the first sealing member 122 .

[0067] In one embodiment, the second sealing member 222 is connected to the first end water retaining frame 21 via a mounting plate 2224 .

[0068] The second sealing member 222 is connected to the first end water retaining frame 21 through a right-angled mounting plate 2224 , so that the second sealing member 222 is arranged opposite to the first sealing member 122 to ensure that the second sealing member 222 can be sealed and connected to the door groove 4 .
