Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The wind speed measuring device 100 of the embodiment of the present invention is described below with reference to the drawings. As shown in fig. 1 and 2, a wind speed measuring device 100 according to an embodiment of the present invention includes a floating body 1, a rotating portion, and a wind radar 2.
The rotating part is rotatably arranged on the floating body 1, and the rotating axis of the rotating part extends along a first direction. The wind measuring radar 2 is rotatably hung on the rotating part, and the rotating axis of the wind measuring radar 2 extends along the second direction. The first direction is perpendicular to the second direction, and the first direction and the second direction are not in the same direction as the up-down direction. The wind measuring radar 2 is hung on the rotating part, so that the wind measuring radar 2 has certain inertia relative to the rotating part, and the wind measuring radar 2 keeps stable relative to the rotating part.
The first direction is perpendicular to the second direction, and the first direction and the second direction are not in the same direction as the up-down direction. To better explain the solution of the embodiment of the present invention, the following is to specifically explain that when the floating body 1 is in a flat state, the first direction and the second direction are both horizontal directions, the direction in which the laser transceiver module of the wind radar 2 transmits and receives the laser signal is the same as the up-down direction, and any two of the first direction, the second direction and the up-down direction are perpendicular to each other.
Specifically, the rotation axis of the rotation part extends in the first direction, so that the floating body 1 and the rotation part can be rotated about the rotation axis extending in the first direction. Therefore, when the floating body 1 shakes or tilts in the second direction, the floating body 1 can rotate around the rotation axis extending in the first direction, and the rotation part rotates relative to the floating body 1 under the action of the gravity and inertia of the wind-measuring radar 2. The in-process of body 1 at the slope of second direction, rotation portion and body 1 relative rotation can reduce the range that wind measuring radar 2 took place to incline in the second direction to make wind measuring radar 2's laser transceiver module receive and dispatch laser signal's direction and the first angle of predetermineeing of contained angle between the upper and lower direction, guarantee wind measuring radar 2's measurement accuracy.
The rotation axis of the wind radar 2 extends in the second direction, and the rotation portion and the wind radar 2 can be made to rotate about the rotation axis extending in the second direction. Therefore, when the floating body 1 shakes and inclines in the first direction, the rotating part and the floating body 1 incline together, the rotating part can rotate around the rotating axis extending in the second direction, and the wind measuring radar 2 rotates relative to the rotating part under the action of self gravity and inertia. The in-process of body 1 (rotation portion) slope in the first direction, and anemoscope radar 2 rotates with rotation portion relatively and can reduce anemoscope radar 2 and take place the range of slope in the first direction to make the laser transceiver module of anemoscope radar 2 receive and dispatch laser signal's direction and the first angle of predetermineeing of contained angle between the upper and lower direction can less than or equal to, guarantee anemoscope radar 2's measurement accuracy.
When the floating body 1 rocks or tilts in a third horizontal direction (the third horizontal direction is neither parallel to nor perpendicular to the first direction nor the second direction), the tilting of the floating body 1 in the third horizontal direction can be decomposed into a certain tilting of the floating body 1 in the first direction and a certain tilting in the second direction. So that when the floating body 1 is tilted in the third horizontal direction, the rotation part and the floating body 1 rotate relatively, and the rotation part and the wind radar 2 also rotate relatively.
The in-process that body 1 took place the slope on this third horizontal direction, rotation portion and body 1 relative rotation can reduce the range that anemometry radar 2 took place the slope in the second direction, and anemometry radar 2 can reduce the range that anemometry radar 2 took place the slope in the first direction with rotation portion relative rotation to make the direction of anemometry radar 2 laser transceiver module receiving and dispatching and the contained angle between the upper and lower direction can the first angle of predetermineeing of less than or equal to, guarantee anemometry radar 2's measurement accuracy.
The wind speed measuring device 100 of the embodiment of the invention can rotate on the floating body 1 by arranging the rotating part, the wind measuring radar 2 can rotate on the rotating part, and the rotating axis of the rotating part is vertical to the rotating axis of the wind measuring radar 2. Thereby make body 1 rock, when slope on the sea, rotation portion and wind-finding radar 2 carry out corresponding rotation, and then reduce body 1 and rock the influence to wind-finding radar 2 to be convenient for wind-finding radar 2 keeps stable under its gravity and inertial effect. From this, the laser transceiver module of anemometry radar 2 receives and dispatches the contained angle between the direction of laser signal and the upper and lower direction can be less than or equal to first predetermined angle to guarantee anemometry radar 2's measurement accuracy.
Therefore, the wind speed measurement device 100 of the embodiment of the present invention has the advantages of high stability and high measurement accuracy of the wind measuring radar 2 when floating.
As shown in fig. 1 and 2, a wind speed measuring device 100 according to an embodiment of the present invention includes a floating body 1, a rotating portion, and a wind radar 2.
The rotating part is rotatably arranged on the floating body 1, and the rotating axis of the rotating part extends along a first direction. The wind measuring radar 2 is rotatably hung on the rotating part, and the rotating axis of the wind measuring radar 2 extends along the second direction. The first direction is perpendicular to the second direction, and the first direction and the second direction are not in the same direction as the up-down direction. The first direction is perpendicular to the second direction, and the first direction and the second direction are not in the same direction as the up-down direction. For ease of understanding, the first direction is hereinafter specifically described as a left-right direction as indicated by an arrow a in fig. 1, and the second direction is hereinafter specifically described as a front-rear direction as indicated by an arrow B in fig. 1.
The rotation axis of the rotation part extends in the left-right direction, so that the floating body 1 and the rotation part can rotate around the rotation axis extending in the left-right direction. Therefore, when the floating body 1 rocks or tilts in the front-rear direction, the floating body 1 can rotate around the rotation axis extending in the left-right direction, and the rotation part rotates relative to the floating body 1 under the action of the gravity and inertia of the wind radar 2. In the process that the floating body 1 inclines in the front-back direction, the rotating part and the floating body 1 rotate relatively to reduce the inclination amplitude of the wind measuring radar 2 in the front-back direction, so that the included angle between the direction of the laser receiving and transmitting module of the wind measuring radar 2 for receiving and transmitting laser signals and the up-down direction can be smaller than or equal to the left-right preset angle, and the measurement accuracy of the wind measuring radar 2 is ensured.
For example, from the visual angle on the right side of floating body 1, when floating body 1 inclines forward, floating body 1 is for anticlockwise rotation on an average, anemometry radar 2 is also for anticlockwise rotation on an average, rotation portion clockwise rotates relative to floating body 1 under the effect of gravity and inertia of anemometry radar 2 to reduce anemometry radar 2 anticlockwise rotation's range, and then make the direction of laser signal received and dispatched by the laser transceiver module of anemometry radar 2 and the contained angle between the upper and lower direction can be less than or equal to and control predetermined angle, guarantee anemometry radar 2's measurement accuracy.
The rotation axis of the wind radar 2 extends in the front-rear direction, so that the rotation portion and the wind radar 2 can be rotated about the rotation axis extending in the front-rear direction. Therefore, when the floating body 1 shakes or tilts in the left-right direction, the rotating part tilts together with the floating body 1, the rotating part can rotate around a rotating axis extending in the front-back direction, and the wind measuring radar 2 rotates relative to the rotating part under the action of self gravity and inertia. The in-process of body 1 (rotation portion) at the left and right sides direction slope, the relative rotation of anemoscope radar 2 and rotation portion can reduce the range that anemoscope radar 2 takes place to incline about at the direction to make the contained angle between the direction of the laser transceiver module receiving and dispatching laser signal of anemoscope radar 2 and the upper and lower direction can be less than or equal to about predetermineeing the angle, guarantee anemoscope radar 2's measurement accuracy.
When the floating body 1 rocks or tilts in a third horizontal direction (the third horizontal direction is neither parallel nor perpendicular to the left-right direction nor the front-rear direction), tilting of the floating body 1 in the third horizontal direction can be decomposed into tilting of the floating body 1 in a certain degree in the left-right direction and also in a certain degree in the front-rear direction. So that when the floating body 1 is tilted in the third horizontal direction, the rotation part and the floating body 1 rotate relatively, and the rotation part and the wind radar 2 also rotate relatively.
The in-process that body 1 took place the slope on this third horizontal direction, rotation portion and body 1 relative rotation can reduce anemometry radar 2 and take place the range of slope in the front and back direction, and anemometry radar 2 rotates the range that can reduce anemometry radar 2 and take place the slope in the left and right sides direction with rotation portion relative rotation to make the contained angle between direction and the upper and lower direction of laser signal's of anemometry radar 2 receiving and dispatching orientation can be less than or equal to about predetermineeing the angle, guarantee anemometry radar 2's measurement accuracy.

For example, the upper surface of the body 11 is circular, and the lower end of the column 12 is located at the center of the upper surface of the floating body 1.
The support frame 13 is provided at the upper end of the upright 12, for example, the support frame 13 includes a first side plate 131, a second side plate 132 and a bottom plate 133, and the bottom plate 133 is connected to the upper end of the upright 12.

The support frame 13 can make marine wave beat the probability of hitting support frame 13 less at the height more than or equal to 3 meters that body 1 is located to make marine wave beat the probability of hitting anemoscope radar 2 less, and then reduce anemoscope radar 2 and damage or reduce the probability that the wave influences the laser transceiver module of anemoscope radar 2 and receive and dispatch laser signal.
