Gravity tensioning device

Abstract

The invention relates to the field of high-altitude wind power generation, and particularly discloses a gravity tensioning device. The device further comprises several fixed pulley sets arranged parallelly and fixed to the upper portion of a rack and several movable pulleys arranged at the lower portion of the rack, wherein the fixed pulley sets comprise first fixed shafts installed on the rack, and several fixed pulleys are installed on the first fixed shafts; the movable pulleys are in one-to-one correspondence with the fixed pulleys and are further connected with balance weights, and the whole balance weights are in a tendency that the front portions are light, and the back portions are heavy. Compared with the prior art, the provided gravity tensioning device is a cable storage devicewith a cable buffering function, the buffering capacity is large, frictional loss of cables is less, and the device is beneficial for prolonging the service life of the cables.

Description

technical field [0001] The invention relates to the field of high-altitude wind power generation, in particular to a gravity tensioning device. Background technique [0002] Wind energy is a clean and renewable energy source, and the wind energy stored in the sky is more than 100 times the total energy demand of human society. High-altitude wind energy has the characteristics of high wind speed, high average energy density, wide geographical distribution, high stability, and continuous operation all year round. How to make full use of high-altitude wind energy for human use is a hot topic that scientific researchers have been paying attention to. The many advantages of high-altitude wind energy have also attracted more and more attention from all over the world. [0003] The utilization of high-altitude wind energy is to collect wind energy at high altitude, convert the wind energy into mechanical energy, and finally convert the mechanical energy into electrical energy or o...

Problems solved by technology

However, this solution increases the complexity of the ground power generation system by adding a cable buffer device, which makes the structure of the whole ground power generation system cumbersome and increases the floor area of ​​the ground power generation system. Each section adds a lot of difficulty

At the same time, the pulley blocks of the cable buffering device are arranged side by side, and the buffering capacity is relatively small. If the buffering capacity is to be increased, the device needs to be expanded horizontally, which further increases its floor area and further increases the buffer capacity. Increased distribution difficulty

In addition, the cable buffer mechanism mainly realizes its function through the movable pulley and the elastic device installed on the movable pulley. The elastic device is easy to fail in long-term use, and the functional stability is poor.
