Cycloid water turbine installation retainer with measuring function

Abstract

The invention aims to providing a cycloid water turbine installation retainer with a measuring function. The cycloid water turbine installation retainer comprises an average disc, a centre fixed bolt, and a measuring holding mechanism, wherein the measuring holding mechanism comprises a first spoke, a second spoke, an arc guide rail, press wheels, a pointer and an upper clamping apparatus press plate; one end of the first spoke is provided with a rectangular slot hole, the other end of the first spoke is solid, and the solid end of the first spoke is fixed on the average disc through the centre fixed bolt; the first spoke is also fixed together with the average disc through a hole of a self spoke surface and a hole of the average disc, one end of the second spoke is fixed in the rectangular slot hole of the first spoke, and the other end of the second spoke is connected with the arc guide rail with scales through an arc guide rail frame; and the arc guide rail frame is provided with the press wheels, the upper end of the arc guide rail is provided with an upper clamping apparatus press plate, the pointer is arranged on the arc guide rail frame and points to the scales of the arc guide rail, and the axle wire of the second spoke points to the rotating center of a blade. The cycloid water turbine installation retainer provided by the invention has the advantages that the structure is simple, and the assembly and transportation are easy.

Description

technical field [0001] The invention relates to an installation measuring device, in particular to an installation measuring device of a cycloidal water turbine. Background technique [0002] Tidal current energy turbines can be divided into vertical axis and horizontal axis according to the arrangement of the axis of rotation. Among them, the cycloidal turbine in the vertical axis turbine can realize high and low speed operation according to the working conditions, has a high energy capture rate, and has self-starting ability, which has attracted widespread attention. Since the cycloidal turbine needs to adjust the blade deflection law in real time during operation, most of the structures are complex, which brings great inconvenience to assembly and testing. Cycloidal turbines have high requirements for the law of the blade deflection angle, so the position of each blade needs to be determined in advance before installation. At present, most of them are realized by marking...

Problems solved by technology

Such a method is difficult to find and is easy to be worn off after the turbine has been used for a period of time, and it is also not conducive to installing all the blades at one time

At the same time, due to the complexity of the blade adjustment structure, many sensors and additional circuits are often needed to measure the manufacturability of the installed turbine and the adjustment error of the adjustment mechanism during operation, and even a separate installation structure needs to be designed for it.

In addition, when the cycloidal turbine fails, it also needs a mechanism to maintain the existing blade posture so that the cause of the problem can be better found during disassembly. The Difficulty of Analyzing the Causes of Hydraulic Turbine Faults
