Embodiment Construction

[0019] Such as figure 1 with figure 2 As shown, the hydraulic rotary weir gate designed by the present invention includes a door panel 1 and an oil cylinder 2; A mounting seat 4 is provided, and a rotating shaft 5 is provided on the mounting seat 4; the bottom of the door panel 1 is rotationally connected with the rotating shaft 5; the contact seal between the door panel 1 and the flow channel base 3 is provided.

[0020] Further, the bottom surface of the flow channel base 3 upstream of the door panel 1 is higher than the bottom surface of the flow channel base 3 on which the installation seat 4 is installed; in this way, the door panel can be placed in a horizontal position, so that the flow channel is fully opened.

[0021] Further, the bottom surface of the flow channel base 3 includes a high section 3.1 and a low section 3.2, and the high section 3.1 and the low section 3.2 have a stepped structure; Transition to paragraph 3.2.

[0022] Further, the rotation center of...

Abstract

The invention discloses a hydraulic rotary weir gate, which includes a door plate and an oil cylinder, the fixed end of the oil cylinder is fixed on the base of the flow channel, the driving end is hinged to the end surface of the door plate; the base of the flow channel is provided with a mounting seat, the The mounting seat is provided with a rotating shaft; the bottom of the door plate is connected to the rotating shaft in rotation; the two sides of the door plate are contact-type sealed with the side wall of the flow channel base. The installation space of the present invention, whether it is underground or on the ground, is much smaller than that of the existing weir gate. At the same time, the oil cylinder can be installed below the ground without affecting the landscape on the ground; the door panels can be stopped at different angles to control different Distribute water flow or regulate different upstream water levels.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage equipment, in particular to a hydraulic rotary weir gate. Background technique [0002] In my country's urban water supply and drainage projects, water supply devices and drainage devices often have a clear division of labor, and each uses its own field. As the construction of water supply and drainage systems in cities in our country is becoming more and more perfect, the demand for devices that can be used for both water supply projects (water distribution) and drainage projects (adjustment of upstream water level) is also increasing. Therefore, there is an urgent need for a weir gate technology that can be used not only in water supply projects but also in drainage projects. [0003] The existing weir gate requires an increased installation space, and both underground and above-ground spaces have corresponding design requirements, which has caused damage to the ground landsca...
