Abstract

The invention provides a cable fixing and mounting method, and relates to the technical field of wind power generation. The cable fixing and mounting method comprises the following steps of enabling a communication cable to be penetrated in a threading pipe, and filling the gap between the communication cable and the threading pipe with a foaming filling agent, wherein in the step of filling with the foaming filling agent, a foaming gun is adopted for filling; the foaming gun is also equipped with a foaming pipe, a hose and a hoop; the gun pipe of the foaming gun is inserted into the hose from one end of the hose to be fixed with the hose through the hoop; and the foaming pipe is inserted in the other end of the hose and is fixed with the hose through the hoop. The cable fixing and mounting method is low in requirement, high in applicability, suitable for workshop mounting or after-sales repair operations, low in cost, free of influence to personal safety, high in working efficiency, good in effect, and capable of effectively solving the problem of abrasion between the communication cable and the threading pipe and eliminating potential quality hazards in the movement process of the wind power generator unit.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method for fixing and installing cables. Background technique [0002] Wind power generation is a clean electricity production method nowadays, and signal control is of course extremely important in wind turbines. Take the 1.5MW wind turbine as an example: [0003] The signal in the 1.5MW wind turbine is connected through the communication cable between the slip ring and the hub main control cabinet, and the communication cable passes through the main shaft and the gearbox, and rotates with the main shaft and the gearbox. [0004] The existing scheme is to install a threading pipe inside the main shaft and the speed-increasing box, and the communication cable passes through the threading pipe. [0005] Such a solution is likely to affect power generation due to signal interruption during the power generation process and may cause damage to the generator set, res...
