Gate-free controlled layered water-getting device and method

Abstract

The invention relates to a gate-free controlled layered water-getting device and method. The device comprises a flow leader connected to a reservoir, wherein a plurality of current plates which are layered and are radially arranged on the flower leader; the current plates are fixedly connected to guide walls on two sides of a water inlet channel; a buttress is arranged at the end of the flower leader; a rotary cylinder with a cylindrical barrel is arranged at a radial center pointed by the radial current plates on the buttress; a water inlet and a water outlet are formed on the outer round surface of the barrel at a difference of 180 degrees; and the rotary barrel is connected to a controller through a rotary driving mechanism. The radially arranged current plates are aligned to different water layers. Arbitrary transformational runners can be formed by using the rotary barrel, so that a multi-target layered water-taking effect can be achieved at an elevation of a same water-taking port, and the device is of continuity. The device is simple in structure and convenient to operate. The working and closing states of the layered water-getting device are achieved by means of a simple transmission mechanism. Compared with a conventional layered water-taking facility, the project cost is greatly lowered.

Description

technical field [0001] The invention relates to a stratified water intake device and method without gate control, is a hydraulic device and method, and is a device and method for water intake from water layers of different depths in a reservoir. Background technique [0002] After the reservoir is built and operated, the water temperature structure in the reservoir area is mostly in a seasonal stratified state, and the water temperature has obvious characteristics of stratified distribution along the depth. The upper layer of the reservoir is the surface temperature layer. The water body and the air directly exchange heat, absorbing a lot of heat energy, and the temperature is high. The water temperature in the layer is mixed with each other, and the temperature of the whole layer is basically uniform. , the upper and lower water temperature of the whole layer changes drastically, and the temperature gradient is large; the bottom is the deep water layer, which is less affect...

According to the literature, the current layered water intake measures are usually multiple water intakes or logger door layered water intake measures. Experimental studies have shown that the water intake effect of each water intake in the multiple water intake scheme is single, which cannot meet multiple ecological conditions at the same time. Demand conditions, although the layered water intake of the stacking beam gate can meet different ecological needs by adjusting the water intake elevation, it is not suitable for the renovation of existing projects, and the later operation cost is high

The traditional layered water intake structure often uses multi-layer water intakes or stacked beam doors for water intake, both of which are horizontal water intake methods. The water intake temperature of this water intake method is single. When the downstream ecological requirements are complex, it is necessary to set more layers of water intakes or reduce the number of stacked beam doors. The height of a single section, the resulting consequences are increased project cost, unstable project structure, etc., and poor controllability
