Floating water taking device capable of adjusting water taking depth

Abstract

The invention provides a floating water taking device capable of adjusting the water taking depth, and belongs to the field of reservoir irrigation or drinking water supply. The floating water takingdevice comprises a screw machine, a floating box, a water taking head and water taking pipes; the floating box is arranged on the water surface in a floating mode, the screw machine is fixed to the floating box, the screw machine is provided with a screw extending to the lower side of the floating box in the vertical direction, and the water taking head is fixed to the screw on the lower side of the floating box; and the water taking head is hinged to the upper end of the first water taking pipe through a universal hinge, the lower end of the first water taking pipe is hinged to one end of thesecond water taking pipe through a universal hinge, the water taking head communicates with the second water taking pipe through the first water taking pipe, and the other end of the second water taking pipe is a water diversion outlet. The problems that at present, if layered water taking is adopted in the same reservoir, mechanisms such as a gate, a water taking tower and a hoist need to be arranged, the construction cost is high, only one water taking device is arranged, and consequently the requirements for different water taking purposes cannot be met at the same time are solved.

Description

technical field [0001] The invention relates to a floating water intake device capable of adjusting the depth of water intake, which is suitable for the fields of small reservoir irrigation and human drinking water supply projects. Background technique [0002] At present, for small reservoir irrigation and drinking water supply projects, since irrigation, drinking water supply, reservoir sand washing, reservoir emptying and other water intake devices share one device, most of the time the water taken is the bottom water of the reservoir, and the temperature of the bottom water of the reservoir Low, it is unfavorable to crops during irrigation, and there are more cement sand and dirt deposits at the bottom, and the treatment cost of drinking water supply is higher; [0003] The water intake of the reservoir adopts a layered water intake model, and it is necessary to set up intake gates at different water intake elevations. Setting up the gates requires water intake towers, h...
