Description
技术领域 technical field
本发明涉及的是一种安装测量装置，具体地说是摆线水轮机的安装测量装置。The invention relates to an installation measuring device, in particular to an installation measuring device of a cycloidal water turbine.
背景技术 Background technique
潮流能水轮机按照旋转轴的布置形式可以分为竖直轴和水平轴两类。其中竖轴水轮机中的摆线水轮机可以根据工况实现高低速运行具有较高的能量捕获率，且具有自起动能力受到人们的广泛关注。摆线水轮机由于在运行过程中需要对叶片偏角规律进行实时调整，因此大多结构复杂，这样给装配与检测带来很大不便。摆线水轮机对于叶片偏角的规律有较高的要求，因此在安装前需要事先对各叶片的位置进行确定，目前多数采用在叶片与机身上分别做标识的方法实现。这样的方法找起来困难并且在水轮机使用一段时间后容易被磨掉，同时还不利于将所有叶片一次性安装。同时由于叶片调整结构的复杂，对于安装好的水轮机要想测量其安装的工艺性及调整机构在运行过程中的调整误差，往往需要很多传感器和外加电路，甚至需要为其单独设计安装结构。再有当摆线水轮机发生故障时也需要有一个机构能够使其保持现有叶片姿态以便在拆卸时更好的找到问题发生的原因，可以说很多时候由于不能保持故障时的姿态增加了摆线水轮机故障原因的分析难度。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 the blades and the fuselage separately. Such a method is difficult to find and is easy to be worn off after the water 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 required 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. Difficulty in analyzing the causes of hydraulic turbine failures.
