Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 , figure 2 As shown, the present invention includes a spherical trashstop 1, a circular horn inlet section 2, a control gate valve 3, a pontoon installation section 4, an adjustment section 5 and an elbow section 6 connected in sequence. The water flow enters the trumpet water inlet section 2 after being filtered by the spherical trash net 1, flows through the control gate valve 3, the floating tank installation section 4, the adjustment section 5 and the elbow section 6 and enters the fixed water diversion pipeline. A buoyant tank 7 is connected on the buoyant tank installation section 4, and the two sides of the buoyant tank 7 are respectively connected on the mooring devices 9 on both banks by steel cables 8. The bottom of the adjustment section 5 and the elbow section 6 are respectively provided with U-shaped floats 10,...

Abstract

The invention relates to an adjustable water inlet device for a hydropower station, which is characterized in that the adjustable water inlet device for the hydropower station comprises a spherical strainer, a trumpet water inlet section, a control gate valve, a floating box assembly section, an adjusting section and an elbow pipe section, wherein a floating box is connected to the floating box assembly section; lower parts of the adjusting section and the elbow pipe section are provided with U-shaped floating blocks of a floating pipeline respectively; both sides of the floating box are connected to a mooring line device through steel cables respectively; the adjusting section consists of an upstream spherical universal joint, a downstream spherical universal joint and a connecting pipe which connects the upstream spherical universal joint and the downstream spherical universal joint; and an outlet of the elbow pipe section is connected with a fixed water conduit of a river bank. The adjustable water inlet device for the hydropower station does not require a matched dam project to maintain the underwater embedded depth of a water inlet, does not obstruct a river channel, is favorable for maintaining natural ecology of the river channel, and is widely suitable for the water inlet of a small diversion type hydropower station.

Description

technical field [0001] The invention relates to a water inlet device, in particular to an adjustable water inlet device suitable for a small-scale diversion-type hydropower station without a dam. Background technique [0002] The water inlet is a key part of the water diversion system of a hydropower station. Its structure type and water flow shape are complex, and it is one of the necessary hydraulic structures for water flow from a natural river to a pressurized pipeline. The water inlet is generally divided into an inlet section, a gate section and a gradual transition section. The water inlets of conventional hydropower stations are fixed water inlets. Due to the different water levels of natural rivers or reservoirs in different seasons, in order to ensure that water can be diverted to generate electricity under any circumstances, the water inlet is usually selected in deep water below the upstream dead water level, that is, at a position with a low elevation of the em...
