Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0029] The utility model relates to an anti-backflow weir gate with an oil tank placed horizontally, which is mainly suitable for adjusting water level, water volume and anti-backflow in drainage engineering. The horizontally placed hydraulic cylinder is driven to rotate along the axis of the bottom of the weir gate to promote the lifting of the weir crest to achieve the purpose of adjusting the water level and water volume. Such as figure 1 As shown, it includes a weir gate support body, a weir gate main body 2 that is rotatably connected to the bottom of the weir gate support body ...

The invention relates to an anti-backflow weir gate with a horizontally placed oil cylinder. The anti-backflow weir gate comprises a weir gate support body, a weir gate main body and the oil cylinder, and one end of the weir gate main body is rotatably connected with the bottom of the weir gate support body; and the oil cylinder for driving the weir gate main body to rotate. The anti-backflow weir gate with the horizontally placed oil cylinder is characterized in that the anti-backflow weir gate further comprises a guide rod and an oil cylinder bracket, and the output end of the oil cylinder is connected to the other end of the weir gate main body through the guide rod; and the oil cylinder is horizontally mounted on the upper inner wall of the mounting position through the oil cylinder bracket, and the guide rod is rotationally connected with the oil cylinder and the weir gate main body. Compared with the prior art, horizontal mounting is achieved through the guide rod, so that the height requirement for the mounting space is lowered, and the mounting working condition adaptability of the weir gate is improved.
Description
technical field [0001] The invention relates to drainage engineering, in particular to an anti-backflow weir gate with an oil cylinder placed horizontally. Background technique [0002] At present, the hydraulic rotary weir gate produced at home and abroad generally adopts a whole solid plate as the gate body, and channel steel is welded on the back of the gate body for strengthening support; [0003] For example, Chinese patent CN104131537A discloses a hydraulic rotary weir gate, which includes a door panel and an oil cylinder. There is a rotating shaft on the top; the bottom of the door plate is connected to the rotating shaft in rotation; the contact seal between the two sides of the door plate and the side wall of the flow channel base. Then the above-mentioned weir gate oil cylinder is installed obliquely to drive the circular motion of the weir gate, so a relatively large installation space is required; in addition, this type of hydraulic rotary weir gate adopts a wal...
