Hydraulic automatic adjustable turning weir

Abstract

The invention discloses a hydraulic automatic adjustable flip weir, which comprises a fixed base, wherein both ends of the fixed base are respectively provided with a side plate; a flip shaft is connected between the two side plates; the flip shaft is hinged to a weir plate; the bottom of the weir plate is in seal match with the fixed base; both ends of the weir plate are in seal match with the corresponding side plates; strengthening ribs are arranged on the back of the weir plate; a spring fixing support is connected onto the fixed base; a spring guide rod is connected onto the spring fixing support; a spring is arranged on the spring guide rod in a sleeving manner; a guide block is arranged on the top end of the spring on the spring guide rod in a sleeving manner, and is fixedly connected with a guide block fixing support; the top end of the guide block fixing support is fixedly connected with the strengthening ribs; the bottom end of the guide block fixing support is hinged to the flip shaft. The weir plate can be flipped under pure hydraulic actions, the overflow capacity is increased, the overflow water level before the weir is thus controlled, timely flood discharge is achieved, the weir plate can be reset by means of the spring force, and adjustment of the overflow water level can be adjusted by adjusting the spring force.

Description

technical field [0001] The invention relates to water supply and drainage equipment, in particular to a hydraulic automatic adjustable turning weir. Background technique [0002] Before the municipal rainwater or sewage pipe network overflows to natural water bodies (rivers, lakes, etc.), in order to increase the outlet water level, a water retaining device is usually installed in the direction of the water flow. The weir plate is one of them. The front side of the weir plate can intercept a certain amount of water. When the water level is higher than the height of the weir plate, the water flows over the weir plate and flows to the other side of the weir plate. The weir plate needs to be sealed and cooperated with interception wells and other facilities to effectively intercept the water flow. Therefore, in order to ensure the sealing performance, the weir plate generally adopts a fixed structure, but the overflow height of the overflow plate in this structure is fixed. Onl...
