Problems solved by technology

[0003] At the same time, if the wind field installed on the wind measuring tower is located in the north where the temperature is low in winter or in the area with high humidity, the temperature of the external environment will drop, resulting in a large amount of frost, dew, snow, and rainwater attached to the wind measuring tower. Icing, etc., make the local load of the wind measuring tower too large, which will easily cause the wind measuring tower to tilt or even fall

Embodiment 1

[0034] Such as Figure 1 to Figure 3 As shown, an anti-freezing wind measuring tower is introduced in this embodiment, which includes a vertically arranged tower tube 1, and multiple height surfaces in the middle of the tower tube 1 are respectively connected with a plurality of stay ropes 2 arranged at interval angles. The rope 2 is set tightly and the other end is fixed to the ground; the tower tube 1 is composed of multi-section tower tube sections 11 connected end to end sequentially from bottom to top; The heating wire 4 is used to heat and remove the ice and frost. The stay rope 2 is formed by winding multiple strands of steel wire ropes 21 .

[0035] By setting the heating wire 4 that can be energized and heated on the pull rope 2, the frost attached to the surface of the pull rope 2 is heated and removed, so that the snow and frost attached to the pull rope 2 in low temperature weather such as rain and snow are heated. Clearing, thereby avoiding the thick ice and snow...

Embodiment 2

[0041] Such as Figure 2 to Figure 3 As shown, this embodiment is based on the anti-freezing wind measuring tower described in the first embodiment above, including a vertically arranged tower tube 1, and the tower tube 1 is connected with a plurality of stay ropes 2 arranged at interval angles, and the stay ropes 2 Tightly set, and the other end is fixed to the ground; the pull rope 2 is provided with a heating wire 4 for heating and removing the attached frost, and the power supply input end of the heating wire 4 is connected to the power bus 9 of the anemometer tower through the control switch 8 The pull rope 2 is provided with at least one temperature sensor 7 for detecting the surface temperature of the pull rope 2 , and the temperature sensor 7 is connected to the signal input end of the control switch 8 .

[0042] By arranging the temperature sensor 7 on the stay rope 2 of the wind measuring tower, the temperature on the surface of the stay rope 2 of the wind measuring ...

Embodiment 3

[0049] The difference between this embodiment and the above-mentioned second embodiment is that: the pull cord 2 is provided with at least one weight sensor and / or light sensor for detecting the thickness of frost attached to the surface, and the weight sensor and / or light sensor are controlled The unit 82 is connected with the control switch 8 of the heating wire 4 to output an on-off signal to the control switch 8 (not indicated in the drawings).

[0050] In this embodiment, the control switch 8 provided on the heating wire 4 is an electromagnetic switch, and the electromagnetic switch includes a switch unit 81 for controlling the power on and off of the heating wire 4 and a control unit 82 for controlling the opening and closing of the switch unit 81 according to the received signal. The receiving end of 82 is connected to the signal output end of the corresponding weight sensor and / or light sensor via a signal circuit capable of transmitting signals, and the output end of t...

Abstract

The invention relates to an anti-freezing anemometer tower. The anti-freezing anemometer tower comprises a tower drum, and at least one anemometer is arranged on the tower drum. Multiple height faces in the middle of the tower drum are connected with pull ropes arranged at angle intervals respectively, the pull ropes are arranged in a tightened mode, and the other ends of the pull ropes are fixed to the ground; the tower drum is formed by multiple tower drum segments which are coaxially stacked from bottom to top in sequence; the pull ropes are made of a high-temperature-resistant fireproof material, and the periphery of each pull rope is coated with an anti-freezing agent for preventing frost attachment. As the outer parts of the pull ropes are coated with the anti-freezing agent, the outer surface of the anemometer tower is not prone to frost attachment, accumulation of frost and snow on the anemometer tower is reduced, the anti-freezing capacity of the anemometer tower is improved, and the accuracy of detection data of the anemometer tower under the severe environment is remarkably improved. Meanwhile, the anti-freezing anemometer tower is simple in structure, remarkable in effect and suitable for utilization and popularization.

Description

technical field [0001] The invention relates to a wind-measuring tower in the field of electric power, in particular to an anti-freezing wind-measuring tower capable of resisting severe weather such as low temperature, rain and snow. Background technique [0002] The wind measuring tower is a tower built at the representative site of the proposed wind farm to meet the measurement and evaluation of wind energy resources. The height is usually 70m ~ 100m. , such as 10m, 30m, 40m, 50m, 70m, 90m, 100m and other vertical heights, respectively install supporting beams and install anemometers to collect and monitor wind data at the location of the anemometer tower. Therefore, the requirements for the use of wind measuring towers are more stringent, and the requirements for the anti-tilt reliability of wind measuring towers are higher than those of ordinary wind towers. [0003] At the same time, if the wind field installed on the wind measuring tower is located in the north where ...
