Positioning support guiding frame for offshore wind turbine generator

Abstract

The invention provides a positioning support guiding frame for an offshore wind turbine generator. The positioning support guiding frame comprises a plurality of positioning pile guiding pipes which are arrayed according to a matrix, the tops of the adjacent positioning pile guiding pipes are connected into a whole through connecting rods, and an engineering pile guiding pipe immersed in sea wateris mounted on the middle section of each positioning pile. The overall levelness of the positioning support guiding frame can be manually adjusted at the top end of the positioning support guiding frame through the positioning piles, thus adjustment by a driving mechanism is abandoned, the structure of the positioning support guiding frame is simplified greatly, and the cost of the positioning support guiding frame is also lowered; and mounting of engineering piles are guided by the engineering pile guiding pipes, thus under the premise that the bottoms of the engineering piles are mounted firmly, the mounting precision of the engineering piles is effectively guaranteed, the mounting precision and firmness of the offshore wind turbine generator are guaranteed, thus the vibration quantityof the offshore wind turbine generator can also be controlled within the standard range under the effect of wind power at a higher speed, working safety is ensured, shutdown is avoided, and the generating efficiency of the offshore wind turbine generator is improved.

Description

technical field [0001] The invention relates to a positioning and supporting guide frame for an offshore wind turbine. Background technique [0002] With the aggravation of the energy crisis, green and pollution-free wind energy has been widely used. Among them, offshore wind power has been sought after because of its abundant reserves. At present, the installation and fixing method of offshore wind turbines is to first firmly drive multiple pile tubes as foundation piles into the seabed, then install the platform on the top of the pile tubes, and finally install the wind turbines on the platform. Due to the harsh offshore environment, The wind turbine will also generate vibration when it is working. If the wind speed is high, the vibration of the wind turbine in operation will be increased. Therefore, in order to ensure the safe operation of the wind turbine, the vibration amount during operation has industry standards, and the vibration amount exceeds Standard, it must be...

At present, the installation and fixing method of offshore wind turbines is to first firmly drive multiple pile tubes as foundation piles into the seabed, then install the platform on the top of the pile tubes, and finally install the wind turbines on the platform. Due to the harsh offshore environment, The wind turbine will also generate vibration when it is working. If the wind speed is high, the vibration of the wind turbine in operation will be increased. Therefore, in order to ensure the safe operation of the wind turbine, the vibration amount during operation has industry standards, and the vibration amount exceeds standard, it must be shut down, and can only work again after the wind speed decreases, which directly leads to the generation efficiency of the wind turbine

[0003] In order to solve the above problems, a support platform is set up in the industry, and the support platform is provided with adjustable height feet. The support platform is hoisted to the target sea surface, and then it is sunk to the bottom of the sea. Support the levelness of the platform so that it is in a horizontal state, then install multiple pile tubes vertically on the support platform as foundation piles, and install a platform for carrying wind turbines on the top of the pile tubes, and finally install the wind turbines on the platform In fact, although this installation method can make the installation of the pile tube firm, the adjustment mechanism for adjusting the feet on the support platform is relatively complicated, which increases the complexity of the entire structure and greatly increases the cost of the entire structure
