Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] like figure 1 As shown, the controllable variable-angle diversion pier is preset with cylindrical slots 2 at symmetrical positions on both sides of the concrete foundation 1, and a cylindrical rotating barrel 3 is installed in the cylindrical slots 2 for matching and sealing. In order to prevent the cylindrical rotating barrel 3 from withdrawing at will, a limit structure can be adopted, for example, an annular stopper 9 is arranged around the upper side of the cylindrical slot 2, and an annular step groove is arranged on the upper side of the cylindrical rotating barrel 3, and the annular stopper 9 matches Set in the annular step groove.

[0015] A diversion pier 4 is fixed in the middle of the upper side of the cylindrical rotating bucket 3 . The diversion pier 4 is an arc-shaped structure, and its arc-shaped center is fixed in the correspond...

Abstract

The invention discloses a controllable variable-angle flow diversion pier, which comprises a concrete foundation and a flow diversion pier. Cylindrical slots are respectively preset at symmetrical positions on both sides of the concrete foundation, and a cylindrical rotating shaft is matched and sealed in the cylindrical slots. The barrel has a diversion pier fixed in the middle of the upper side of the cylindrical rotating barrel; an inherent gear ring is set on the inner wall of the cylindrical rotating barrel, and a sealed motor is installed at the bottom of the cylindrical slot in the cylindrical rotating barrel, and a gear is installed on the shaft of the sealed motor. This gear meshes with the ring gear. The invention has the advantages of simple construction, low cost and convenient operation. The angle can be changed with different inflowing water volumes, thereby effectively improving the mainstream effect of the forebay, weakening the backflow area on both sides, and maintaining the flow state of the forebay of the pumping station stable.

Description

Technical field: [0001] The invention belongs to the technical field of channel sedimentation dredging equipment, and in particular relates to a controllable variable-angle diversion pier. Background technique: [0002] When the pumping station draws water from the high-sediment river, the sedimentation of the forebay often occurs, which leads to the decline of the regulation capacity of the forebay and the low operating efficiency of the pumping station. The diversion pier is a common device installed at the bottom of the water inlet of the forebay of the pumping station to improve the sedimentation problem of the forebay. The existing diversion piers are all fixed-angle diversion piers, which can reduce the scope of the main return flow area to a certain extent, but the rectification effect also changes with the change of the incoming water volume, and cannot always maintain high efficiency. Invention content: [0003] Aiming at the problem that the current diversion pi...
