Description

Technical Field

[0001] This application relates to the field of ultrasonic anemometer technology, and more specifically, to ultrasonic anemometers. Background Technology

[0002] An ultrasonic anemometer is an instrument that calculates wind speed and direction by transmitting sound pulses and measuring the time or frequency (Doppler transformation) difference at the receiving end. It is also called an ultrasonic wind meter. An ultrasonic anemometer is also known as an "acoustic anemometer." It is an instrument based on the principle that the speed of sound in air changes with wind speed. Two pairs of sound pulse transmitters and receivers are usually placed at two points d apart. The time t1 for the sound wave to travel from the transmitter to the receiver with the wind is faster than the time t2 for traveling against the wind. If the speed of sound is c, then the wind speed component in the direction of the sound pulse transmitter and receiver, i.e., the wind speed component, is proportional to the time difference between the windward and upstream propagation of the sound wave. If two pairs of sound pulse transmitters and receivers are placed in each of the three mutually perpendicular coordinate systems, then the three wind speed components in the x, y, and z directions can be measured. Because acoustic anemometers have a wide measurement range, high sensitivity, and fast response speed, they are widely used in atmospheric turbulence research.

[0003] Ultrasonic measuring instruments are widely used in wind measurement due to their small size and ease of installation. However, existing ultrasonic anemometers are easily covered by snow and leaves in winter, which affects signal transmission and causes equipment malfunction, requiring additional staff for maintenance. Therefore, they have shortcomings. Utility Model Content

Detailed Implementation

[0026] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1-5 As shown, the ultrasonic anemometer according to an embodiment of this application includes:

[0028] Support component 100 is fixedly installed at a designated location and is equipped with related devices.

[0029] The probe assembly 200 is mounted on top of the support assembly 100. A clamping member is provided at the bottom of the probe assembly 200. An auxiliary heating member is provided inside the bottom of the probe assembly 200 to heat the ultrasonic probe 215 and the internal electronic components 229 to prevent malfunction. A cleaning member is provided inside the top of the probe assembly 200 to blow away snow or leaves on the upper part of the transmitter disk 210 to prevent signal obstruction and to prevent snow from freezing on the upper part of the transmitter disk 210.

[0030] like Figures 1-3 As shown, the support assembly 100 includes a base body 110, four claw hooks 111 are fixedly connected to the bottom of the base body 110, and an outer sleeve 112 and a data socket 114 are fixedly connected to the top of the base body 110. The data socket 114 is connected to the device inside the base body 110.

[0031] Furthermore, the outer sleeve 112 has four equally spaced notches 113 on its side wall to facilitate the sliding of the sliding column 223.

[0032] like Figures 1-2 and Figures 4-5As shown, the probe assembly 200 includes a transmitter disk 210 and a reflector disk 211. The bottom of the transmitter disk 210 is fixedly connected to an inner sleeve 213, which is configured to cooperate with the top of the support assembly 100. An inner mounting compartment 228 is opened in the top of the transmitter disk 210, and electronic components 229 are fixedly installed in the inner mounting compartment 228. The electronic components 229 are connected to the equipment in the support assembly 100. The bottom of the reflector disk 211 is fixedly connected to the top edge of the transmitter disk 210 by four support rods 212. The side walls of both the transmitter disk 210 and the reflector disk 211 are covered with a reflective film layer 214, which can reflect light and prevent damage by birds and insects.

[0033] Furthermore, the top of the transmitting disk 210 is provided with a sloping structure to reduce the amount of objects left on the upper part. For example, snow will slide downwards due to this sloping structure, reducing the amount of residue. Four ultrasonic probes 215 are installed in a ring at equal intervals on the sloping structure. The ultrasonic probes 215 are arranged in pairs facing each other. The ultrasonic probes 215 are connected to the electronic components 229 and play the role of detecting wind speed.

[0034] Furthermore, the inner sleeve 213 has four outer sliding holes 222 equidistantly arranged in a ring on its side wall. The outer sliding holes 222 are arranged in two layers, and the interior of each outer sliding hole 222 is connected to the inner sliding hole 225.

[0035] Furthermore, the clamping component includes a sliding post 223 and a spring 227. The sliding post 223 is slidably disposed within the outer sliding hole 222, with its inner end abutting against the top of the support assembly 100. An outer limiting block 224 is fixedly connected to the outer end of the sliding post 223, and a limiting slider 226 is fixedly connected to the inner end of the sliding post 223. The limiting slider 226 is slidably disposed within the inner sliding hole 225. The spring 227 is sleeved on the outside of the sliding post 223, with its inner end fixedly connected to the side wall of the inner sliding hole 225 and its outer end fixedly connected to the inner side wall of the inner sliding hole 225. For fixed connection, when it is necessary to install the transmitter disk 210 to the top of the base body 110, the inner sleeve 213 is put on the outside of the data socket 114. At this time, when the top of the data socket 114 touches the inside of the slide column 223, the slide column 223 will automatically move outward. In this way, the spring 227 is in an energy storage state. Multiple slide columns 223 and springs 227 cooperate with the side wall of the data socket 114 to increase the clamping force and make installation and disassembly very convenient, which facilitates subsequent maintenance. Moreover, the slide column 223 will be stuck in the notch 113 to prevent rotation.

[0036] Furthermore, the auxiliary heating component includes a heating plate 230, which is laid on the top of the inner installation compartment 228. The heating plate 230 is connected to the electronic components 229 and can heat the ultrasonic probe 215 and the internal electronic components 229, thus preventing the ultrasonic probe 215 and the electronic components 229 from malfunctioning in winter.

[0037] Furthermore, the center of the reflector 211 is provided with a groove, and a circular hole 216 is opened in the center of the groove. A bearing 217 is fixedly installed in the circular hole 216.

[0038] Furthermore, the cleaning components include a shaft 218, a driven fan blade 219, and a driving fan blade 220. The shaft 218 is fixedly installed inside the bearing 217. The driven fan blade 219 is fixedly installed at the bottom of the shaft 218 and is positioned above the ultrasonic probe 215. The driving fan blade 220 is fixedly installed at the top of the shaft 218 and is positioned above the reflector disk 211. A counterweight ball 221 is fixedly connected to the side of the driving fan blade 220. While measuring the wind speed, the wind energy will also cause the driving fan blade 220 to rotate, which in turn drives the driven fan blade 219 to rotate. The wind energy generated downward by the driven fan blade 219 can blow away the snow or leaves remaining on the upper part of the transmitter disk 210, avoiding the situation where a large amount of frozen snow remains on the transmitter disk 210 in winter, which could cause malfunction. Thus, it can also operate normally in winter.

[0039] Specifically, the working principle of this ultrasonic anemometer is as follows: The base body 110 is fixed in a designated position. Multiple sliding pillars 223 and springs 227 are installed at the bottom of the transmitter disk 210 to cooperate with the side wall of the data socket 114, increasing the clamping force and making installation and disassembly very convenient, facilitating subsequent maintenance. The sliding pillars 223 are locked within the notch 113 to prevent rotation. Furthermore, a heating plate 230 is installed on the top of the transmitter disk 210 to heat the ultrasonic probe 215 and its internal electronic components 229, preventing the ultrasonic probe from... In case of malfunction of components 215 and 229 in winter, the reflector 211 is equipped with a shaft 218, driven fan blade 219 and drive fan blade 220. While measuring wind speed, the wind energy will also drive the drive fan blade 220 to rotate, which in turn drives the driven fan blade 219 to rotate. The wind energy generated by the driven fan blade 219 downward can blow away the snow or leaves remaining on the upper part of the reflector 210, avoiding the situation where a large amount of frozen snow remains on the reflector 210 in winter and causes malfunction. Thus, it can operate normally in winter and reduce the number of times workers need to maintain it.

[0040] The above are merely embodiments of this application and are not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
