Water turbine

Abstract

The invention discloses a water turbine. The water turbine comprises a roller and a driving device thereof which are arranged on a power shaft and an arc-shaped flow guiding plate, and further comprises a control device; the arc-shaped flow guiding plate is arranged under the roller; the radian of the arc-shaped flow guiding plate adapts to the circumferential radian of the roller, and a water drainage channel is formed between the arc-shaped flow guiding plate and the roller; the driving device comprises a fixing frame, a left side plate, a right side plate and movable blades; the fixing frame is arranged along the outer surface of the roller and fixedly connected with the roller; one edge of each movable blade is hinged to the fixing frame; the left side plate and the right side plate are fixedly connected to the fixing frame; the left side plate, the right side plate and the movable blades cooperate with the outer surface of the roller to form a water resisting chamber when enteringthe water drainage channel along with the roller; the control device comprises control guide wheels and a front control rail; the control guide wheels are connected to the outer surfaces of the movable blades; and the front control rail is in an arc shape and is fixedly connected to the water inlet end of the arc-shaped flow guiding plate.

Description

technical field [0001] The present invention relates to a water conservancy power generation equipment, in particular to a water turbine. Background technique [0002] A water turbine is a power device that converts water energy into mechanical energy, and is widely used in hydropower and other fields. According to the different setting methods of the power shaft, the water turbine can be divided into vertical type and horizontal type. At present, the vertical type is used most, and the horizontal type is rarely used. [0003] The current horizontal water turbine, such as the technical scheme recorded in the patent patent number of "ultra-low head tumble flow water turbine" CN201720313863.3, "a water inlet chamber is set on one side of the drum and an arc-shaped diversion is set on the lower part of the side. The deflector is connected to the water inlet chamber, and a number of movable blades are evenly arranged on the peripheral surface of the drum. The movable blades ar...

Problems solved by technology

During the rotation of the water wheel, a part of the blades is impacted by the water flow to drive the power shaft to rotate and do work, while the other part of the blades is exposed in the air, and the blades exposed in the air will be subjected to the reverse resistance of the water when they enter the water flow, which will hinder The rotation of the power shaft will beat the water surface to make noise; when the drum rotates and the linkage blade leaves the water surface, the blade cannot be fixed, and the blade is subjected to large air resistance and noise during the rotation of the drum, resulting in low water energy utilization. Less electricity is converted, and the work efficiency is lower
