Embodiment

[0034] The mobile wind field wind speed full-scale height distribution measuring device of this embodiment is as follows: figure 1 As shown, it includes a balloon 110, a vertical cable 500, a first stay cable 410 for fixing the balloon 110, a second stay cable 420 for fixing the balloon 110, a third stay cable 430 for fixing the balloon 110, an anemometer 300; the balloon 110 The left wing 120 and the right wing 130 are provided, and the anemometer 300 is set on the vertical cable 500. However, the position of the anemometer 300 will not affect the measurement result of the anemometer 300, but when the anemometer 300 is set on the vertical cable 500 When the vertical cable 500 is connected to the pulley, the anemometer 300 can conveniently put down the digital anemometer without putting down the balloon, read the measured wind speed data, replace the battery of the anemometer 300, etc. Effect.

[0035] In this embodiment, the balloon 110 is provided with a rotary connector 20...

Abstract

The invention discloses a mobile apparatus for measuring full-scale wind field wind speed height distribution. The apparatus is characterized by comprising a balloon, a vertical stay cable, a first inclined stay cable for fixing the balloon, a second inclined stay cable for fixing the balloon, and a third inclined stay cable for fixing the balloon, and anemographs. The balloon is equipped with a left wing and a right wing. The anemographs are disposed on the balloon, and / or the vertical stay cable, and / or the first inclined stay cable for fixing the balloon, and / or the second inclined stay cable for fixing the balloon, and / or the third inclined stay cable for fixing the balloon. The airship-type balloon is provided with a pair of horizontal wings such that large elevating force is generated on the vertical stay cable under the combined effect of buoyancy on the balloon and lift on the wings after the balloon rises as well as the wings. Therefore, the balloon is prevented from fluttering everywhere under the effect of wind power. The installation of the anemographs is transformed from a conventional supporting manner to suspending manner. Six to ten digital anemographs are arranged on the vertical stay cable over 100m long. By moving the footstones of the inclined stay cables and the vertical stay cable, full-scale measurement of multipoint wind speed height distribution can be performed on a variable wind field of complex topography.

Description

technical field [0001] The invention relates to a mobile wind field wind speed full-scale height distribution measuring device, which belongs to the field of wind speed measuring equipment for wind power generation technology. Background technique [0002] The magnitude of wind speed and the distribution of wind speed in the height direction are important factors in determining the capacity of wind turbines and the height of wind towers. Too high a wind tower height increases the construction cost, but the power generation does not increase; too low a wind tower height leads to insufficient power generation, which reduces the efficiency of investment equipment. Therefore, in wind resource investigation, assessment and feasibility study of wind farm construction, it is necessary to fully understand the wind speed distribution at different heights of the wind farm, so that the length of the blade and the height of the wind tower can be optimally selected according to the capac...
