AI Technical Summary
In a wind farm, the maintenance and replacement of wind speed sensors requires staff to climb to a high place, which consumes manpower and poses safety hazards. At the same time, disassembly or repair operations at high places are inconvenient, which can easily cause small parts to fall and affect installation.
An automatic wind measurement device in the wind farm is designed, including installation columns, lifting columns, rotating motors and rope drawing systems. The pulling ropes are released by the rotating motors. The lifting columns drive the wind speed sensor to slide down to the bottom of the wind measurement tower. After the staff performs maintenance, the motor rotates and causes the sensor to rise and return to position.
The automatic up and down movement of the wind speed sensor is realized, reducing the operation of staff at high altitudes, improving safety and operation convenience, and avoiding the risk of small parts falling.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wind farm wind measurement, in particular to an automatic wind measurement device for a wind farm. Background Technique
[0002] Wind power generation refers to converting the kinetic energy of wind into electric energy. Wind energy is a clean and pollution-free renewable energy source. Using wind power generation is very environmentally friendly, and the wind energy reserve is huge, so it has been increasingly valued by countries around the world.
[0003] When a wind farm is performing power generation operations, it is necessary to collect parameters such as wind speed in the environment. That is, a wind measurement tower is installed at the wind measurement position, and some measurement sensors such as a wind speed sensor are installed at the top of the wind measurement tower to detect the wind power parameters around the wind farm. The wind measurement tower is a tall tower structure used to measure wind energy parameters, that is, a tower-shaped structure used to observe and record the movement of near-surface air currents. In the past, it was mostly built by wind power generation enterprises, meteorological and environmental protection departments for meteorological observation and atmospheric environment monitoring. Currently, since the wind speed sensor is usually installed at the top of the wind measurement tower, and the wind measurement tower is relatively high. When some wind measurement devices such as the wind speed sensor need to be maintained or replaced, the staff needs to climb to the top of the wind measurement tower to disassemble or repair the wind speed sensor, which is very labor-consuming and there are certain safety hazards. In addition, it is inconvenient to carry out disassembly or repair operations at high altitudes, and it is easy to cause some small parts in the wind speed sensor to fall and affect the installation, bringing great inconvenience to the operation.

Detailed Embodiments
[0015] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0016] Refer to Figure 1-2, this embodiment provides an automatic wind measurement device for a wind farm, including a mounting column, which is fixedly installed on the outer surface of the wind measurement tower through a flange seat; a chute is provided on the mounting column, the shape of the chute is convex, a lifting column is arranged inside the chute, auxiliary pulleys are fixedly connected to the front and rear sides of the lifting column, and the auxiliary pulleys are attached to the inner wall of the chute; one end of the lifting column is fixedly connected to a support rod, the other end of the support rod is fixedly connected to a bearing platform, and a wind speed sensor is arranged on the bearing platform; a support plate is arranged at the top of the mounting column, a rotating motor and a bearing seat are arranged on the support plate, the output shaft of the rotating motor is connected to one side of a roller, the other side of the roller is connected to the bearing seat through a rotating rod, a pulling rope is wound around the roller, and the pulling rope is fixedly connected to the top of the lifting column; a slide rail is arranged on the support plate, a moving rod is connected to the slide rail through a slider, and the moving rod is located below the roller; a sleeve is arranged at the end of the moving rod, and the sleeve is sleeved outside the pulling rope.
[0017] One end of an inclined rod is connected to the lifting column, and the other end of the inclined rod is fixedly connected to the support rod. The number of the inclined rods is two, and they are located on the upper and lower sides of the support rod to increase the stability of the support rod.
[0018] A counterweight block is arranged at the bottom of the lifting column to increase the sliding stability of the lifting column.
[0019] A limiting block is arranged inside the chute to limit the lifting column. When the lifting column abuts against the surface of the limiting block, the stability of the lifting column can be increased.
[0020] When the utility model is in use, when the wind speed sensor needs to be repaired, the rotating motor runs to rotate the roller to release the pulling rope.
