Spiral type magnetic suspension water turbine

Abstract

The invention discloses a spiral type magnetic suspension water turbine which is simple in structure, durable and higher in efficiency. According to the technical scheme, the outer edge, with a certain length, of the lower segment or rear segment of a water turbine spindle is sleeved with an inner spiral pipe with two sealed ends, multiple spiral blades are connected, the inner edges of the blades are mounted on the periphery of an inner spiral pipe, the outer edges of the spiral blades and the inner walls of the outer spiral pipe and the inner spiral pipe are connected into a whole, a movable magnet and a fixed magnet which are mutually exclusive are additionally arranged between the outer side of the plane of the top heads of the two ends of the outer spiral pipe and a bearing disc, a movable magnet and a fixed magnet which are mutually exclusive are arranged at the position, corresponding to the upper and lower circumference of the outer edge of the outer spiral pipe, of a fixed bearing frame, or at least three flat type backup wheels are arranged at the position, corresponding to the circumference of the outer edge of the outer spiral pipe, of a support in a front and back or up and down manner, are arranged at equal distances and are tightly attached to the outer edge of the outer spiral pipe, a generator rotor is directly mounted on the position of the upper segment or front segment of a water turbine spindle; the spiral blade and the whole water turbine are actively pushed by the water to rapidly run, and the generator is driven in the running process.

Description

technical field [0001] The invention relates to a water turbine in a hydroelectric power station, more precisely and more specifically, a power device—a water turbine—that drives a generator with the thrust of water flow. Background technique [0002] As we all know, in a hydropower plant, the generator cannot be directly driven by water, but the water turbine is driven by the thrust of the water flow, and the generator is driven to rotate during operation to perform work. There are many kinds of water turbines in the prior art, among which the most representative one is the axial flow water turbine, whose structure and working principle are as follows: figure 1 Shown: the bearing seat 4 with radial bearing in the upper guide installed on the support frame 1, the bearing seat 6 with radial bearing in the middle guide and the bearing seat 7 with thrust bearing are respectively located on the central shaft 5 of the generator The top end of the upper end and the outer edge of ...

Problems solved by technology

[0003] Its disadvantages are that the flow of water passing through the blades is too short and the thrust is small; the second is that the water will pull the turbine down during the downward flow, and it will not move down due to the existence of thrust bearings, but it will move downward. It will bring severe frictional resistance to the thrust bearing, which must consume a certain amount of energy (water energy) as the price, and there are disadvantages such as shortened service life of the bearing
