Embodiment 1

[0050] Such as figure 1As shown, a wind sensor testing device includes a support rod 22 connected to a fixed base 21 and a fixed base 21, and the support rod 22 is used to install the wind sensor 1, such as figure 1 and 4 As shown, in actual use, the wind sensor 1 can be a wind speed sensor (such as a wind cup) or a wind direction sensor (such as a wind vane).

[0051] Such as figure 1 , 2 As shown in and 3, the wind sensor test device also includes a locking mechanism, and the locking mechanism includes:

[0052] The first mounting seat 5 is used to be fixed on the body 2;

[0053] The locking lever 6 is slidably arranged on the mounting seat. The locking lever 6 has a locking working position and an unlocking working position. When the locking working position is locked, the locking lever 6 moves upwards to cooperate with the rotating part 3 to prevent rotation Part 3 rotates, and when unlocking the working position, the locking lever 6 moves downward and no longer coop...

Embodiment 2

[0080] Such as Figure 6 and 7 As shown, this embodiment discloses a wind sensor testing device. The difference from Embodiment 1 is that it also includes a laser auxiliary mechanism. The laser auxiliary mechanism in this embodiment includes:

[0081] The lower dial 25 is relatively fixed with the support 17, and the circumferential direction of the lower dial 25 has an angle score line (omitted and not shown in the figure);

[0082] Lower pointer 26 is installed on the lower dial 25 in rotation, and the lower pointer 26 is used to point to the angle mark line of the lower dial 25, and the axis of rotation of the lower pointer 26 coincides with the axis of the lower dial 25;

[0083] The upper dial 27 is located above the lower dial 25, and the circumference of the upper dial 27 has an angular scale line (omitted and not shown in the figure), the upper dial 27 and the lower dial 25 are coaxially arranged, and the support rod 22 After the wind sensor 1 is installed, the wind ...

Abstract

The invention discloses a laser auxiliary mechanism and a wind sensor testing device. The laser auxiliary mechanism comprises a lower dial which is relatively fixed with a support, a lower pointer which is rotationally mounted on the lower dial, an upper dial located above the lower dial, an upper pointer which is rotationally mounted on the upper dial, a laser emitter which is fixed relative to the upper pointer and can be driven to rotate synchronously when the upper pointer rotates, and a laser signal receiver arranged on the lower pointer, wherein, angle graduation lines are arranged in the circumferential direction of the lower dial, angle graduation lines are arranged in the circumferential direction of the upper dial, and the upper dial and the lower dial are coaxially arranged. According to the invention, the position of the laser emitted by the laser emitter can be changed by adjusting the position of the upper pointer, the laser emitter can emit laser to the lower dial, whena wind sensor shields the laser, a surface wind sensor rotates in place, the laser auxiliary mechanism can assist the installation and adjustment of the wind sensor, and the invention is more convenient and visual compared with the prior art.

Description

technical field [0001] The invention relates to the field of wind sensor testing, in particular to a laser auxiliary mechanism of a wind sensor testing device and a wind sensor testing device. Background technique [0002] Wind is one of the most important observation elements in meteorological observation. Wind has a major impact on industrial and agricultural production, transportation and people's lives. Strong wind is one of the main disastrous weathers in my country. Strong wind also enhances evaporation, which makes crops suffer from water imbalance and drought. Strong winds in winter often cause people and animals in pastoral areas to lose their way and freeze to death due to heavy wind and snow and poor visibility. At the same time, blowing snow will block roads, making it difficult to carry out rescue work and aggravate the disaster; strong winds in spring are very destructive. Destruction of houses; typhoons in summer mainly endanger the safety of cities and peop...
