Problems solved by technology

If the above-mentioned rotary weir gate is used, there is the following problem: when the water level downstream of the rotary weir gate is higher than the maximum overflow height at the top when the rotary weir gate is closed to the vertical position, the downstream water body will overflow through the upper part of the rotary weir gate. Waterlogging occurs due to backflow of inflow, which poses a safety hazard; if complete anti-backflow is to be achieved, the height of the weir gate needs to be increased, the driving force becomes larger, and the specification of the oil tank becomes larger, resulting in higher costs
[0004] Due to the special structure of the above-mentioned rotary weir gate, it cannot be applied to some drainage pipes that require flow adjustment, such as sewage interceptor pipes or primary rain pipes, and the scope of application is small.

Embodiment 1

[0042] see figure 1 , figure 2 , image 3 , Figure 4 As shown, the embodiment of the present invention provides a hydraulic rotary weir gate, including: a door frame 11, a door leaf 22, a sealing assembly and a driving device 4, the door frame 1 and the door leaf 2 are sealed and connected by a sealing assembly, and the driving device drives the door Page 2 rotates within the range of 0°-90°.

[0043] In this embodiment, the door frame 1 is a frame with a square opening surrounded by a top plate 10, two side plates 11 and a base 12, wherein the square opening corresponds to the size of the water outlet when it is installed and used, and the bottom plate is connected to the door leaf 2. A bottom seal 30 is provided between the base 12 and the bottom of the door leaf 2 . Wherein the top plate 10, the side plate 11 and the base 12 can be welded integral structure, also can be split structure, assemble on site, convenient transportation.

[0044] The leaf door in this imple...

Embodiment 2

[0049] On the basis of Embodiment 1, the base 12 in Embodiment 2 includes a cylindrical portion 13 and a mounting seat 14 abutting with the cylindrical portion 13 . The side of the cylindrical part 13 opposite to the door leaf 2 is provided with an arcuate surface 15. The surface curve of the arcuate surface 15 is consistent with the rotation track of the leaf door. The cylindrical part 13 and the mounting seat 14 are assembled into a hollow structure, and its interior The hollow structure is provided with an ear plate 16 through which the base 12 is connected to the door leaf 2, and the mounting seat 14 is provided with bolt holes for connection to the civil foundation.

[0050] In the present embodiment, the door leaf 2 is connected to the base 12 through the connecting arm 21, and the connecting arm 21 is in a C-like shape, with two horizontal sections and a vertical section, and the two horizontal sections are connected with the two ends of the vertical section, and are loc...

Embodiment 3

[0056] The diversion wells or outlets installed with the above-mentioned hydraulic rotary weir gates include:

[0057] The civil foundation with the water outlet, the door frame 1 of the hydraulic rotary weir gate is installed on the civil foundation around the water outlet, and the two sides of the door frame 1 and the civil foundation are fixed by secondary pouring; the fixed end of the oil cylinder 40 and the door leaf 2 respectively on both sides of the water outlet. At the shortest stroke of the oil cylinder 40, the door leaf 2 and the door frame 1 realize four-sided sealing. The top plate 10 of the door frame 1 is fixed on the civil foundation through anchor bolts, which is convenient for installation and maintenance.

[0058] The diversion well of this embodiment has a water inlet, a first water outlet and a second water outlet, wherein the first water outlet is connected to a sewage pipe, a sewage treatment plant or a storage tank through a sewage intercepting pipe, a...
