Embodiment Construction

[0026] A vertical axis wind turbine with front edge rotation, including a chassis 8, a hollow column 4 is welded perpendicular to the horizontal direction above the center of the chassis 8, and upper and lower thrust bearings 2 are installed on the hollow column 4, and the thrust bearing 2 is covered with Sleeve rods, the bolts on the sleeve rods are connected to the support rods 3, welding is performed between the support rods 3 and the blades 14, the wind turbine blades 14 are vertically arranged and connected to the support rods 3, and the blades are evenly distributed along the circumference of the column to form a wind wheel. The wind wheel realizes the absorption and conversion of wind energy.

[0027] The chassis 8 can be a reinforced concrete platform, can be a steel plate, and can also be a steel frame structure. During construction, the upper surface of the chassis 8 is required to be parallel to the horizontal plane. Hollow column 4 adopts seamless steel pipe or al...

Abstract

The invention discloses a vertical axis wind turbine with rotating cylinders on the front edge. A hollow stand column is welded on the center of a chassis vertically. An upper thrust bearing and a lower thrust bearing are mounted on the hollow stand column. Loop bars sleeve the thrust bearings, and are connected with supporting rods. The supporting rods are welded with blades. The blades of the wind turbine are vertically arranged and are connected together with the supporting rods. The blades are circumferentially and uniformly distributed along the hollow stand column to form a wind wheel. A gear is mounted at the excircle of the lower thrust bearing, and is welded together with a gear of a generator to form a gear pair. The generator is fixed in a box body on the chassis. An arc slab is fixed on the box body, and is welded together with an internal gear. The blades and the rotating cylinders on the front edge are clamped together through clamping groove parts at the upper ends and the lower ends of the blades. The rotating cylinders on the front edge are supported and fixed through thrust bearings, and the thrust bearings are sleeved by grooves of the clamping groove parts in an interference fit manner. External gears are mounted at the lower ends of the rotating cylinders on the front edge. The external gears are meshed with the internal gear outside the rotating cylinders. The vertical axis wind turbine is reasonable in structure, and high in working performance.

Description

technical field [0001] The invention relates to a vertical axis wind turbine with a front edge and a rotating cylinder. Background technique [0002] The development and utilization of wind energy is one of the effective ways to solve the energy crisis. Although the horizontal axis wind generator currently occupies the main market, this kind of wind generator has strict requirements on the wind direction, high cost, short service life, and narrow application range of wind speed. [0003] It is difficult to improve the wind energy utilization efficiency of traditional vertical axis wind turbines. During the movement of vertical axis wind turbines, the range in which a single blade really plays a role in providing lift is limited. Most of the existing vertical-axis wind turbines use lift-type wind turbines. [0004] According to the limit of Bates theory, the wind energy utilization rate of traditional wind turbine blades has a limit value. In practice, the wind energy util...
