Embodiment Construction

[0031] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] The connecting parts involved in the present invention are as figure 1 As shown in and 2 , it is used to connect two screws or bolts 6 together. The connecting parts include: a sleeve 1 , two nut retaining rings 2 , two hex nuts 3 and a spring 4 . A hexagonal channel 5 is arranged inside the sleeve 1 . The channel 5 forms a clearance fit with the hex nut 3 , and the two hex nuts 3 are located in the channel 5 and can slide in the channel 5 . The screw threads of the two hex nuts 3 are in opposite directions. The spring 4 is placed in the channel 5 between the two hex nuts 3. The inner diameter of the spring 4 is larger than the screw diameter of the screw o...

Abstract

The invention discloses a connector used for connecting two bolts or screws together. The connector comprises a sleeve, two polygonal nuts, two nut retaining rings and a spring, a polygonal channel is arranged inside the sleeve, the two polygonal nuts are positioned in the channel and are in clearance fit with the channel and capable of sliding along the channel, thread directions of the two polygonal nuts are opposite, the spring is positioned in the channel and positioned between the two polygonal nuts, the two nut retaining rings are mounted at two ends of the sleeve respectively, and the diameter of a middle hole of each nut retaining ring is larger than the screw diameter of each of the screws or the bolts. The invention further discloses a sectional type wind turbine blade which comprises at least two sections of blade portions, each two adjacent blade portions are connected to a whole through the bolts or the screws and the connector. The connector has the advantage of convenience in connection and facilitates field operation and mounting of the sectional type wind turbine blade.

Description

technical field [0001] The invention relates to a connection component and a segmented wind rotor blade using the connection component. Background technique [0002] Wind energy is an important renewable energy. The vigorous development of wind energy can reduce the dependence on fossil energy and is conducive to the sustainable development of economy and environment. With the development of the market and technology, increasing the power generation of a single wind turbine unit has become the direction of wind power development. Wind rotor blades are the key components of wind turbines. The optimization of aerodynamic shape and the increase of blade length are important ways to increase the power generation of a single machine. Siemens has produced wind turbine blades up to 75m long, which are currently the longest blades in the world. However, the transportation of super-large blades is very difficult and the transportation cost is extremely high, which has become a bott...
