Description

Technical Field

[0001] This utility model relates to the field of anemometer technology, specifically to an automatic anemometer for wind fields. Background Technology

[0002] Automatic wind farm anemometers are devices used to measure meteorological parameters such as wind speed and wind direction in real time. They are widely used in wind power generation, meteorological monitoring, environmental research and other fields. Their main function is to help users conduct automated wind resource assessment and real-time monitoring in wind farms or other locations that require wind speed and wind direction data.

[0003] When the wind speed is measured, the natural wind blows the fan blades to rotate. The wind gauge can detect the wind force of the wind field by detecting the rotation speed of the fan blades. Usually, the wind field is located on land. However, when the wind field contains water, the wind gauge needs to be installed inside the water. However, the water level of the water changes. When the water level rises, the rising liquid overflows the wind gauge and damages the internal components of the wind gauge. Therefore, we propose an automatic wind gauge for wind fields. Utility Model Content

[0004] To address the shortcomings of existing automatic wind field anemometers, this invention provides an automatic wind field anemometer with an adjustable start screw that allows for height adjustment. When the water level rises, the float contacts the water surface and rises, allowing for adjustment of the height of the horizontal plate outside the threaded sleeve. This invention solves the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: an automatic wind field anemometer, including a mounting bracket, a lead screw installed inside the mounting bracket, a threaded sleeve installed on the external thread of the lead screw, a horizontal plate movably sleeved on the external threaded sleeve, a mounting sleeve fixed in the middle of the horizontal plate, a mounting column movably sleeved inside the mounting sleeve, a circular frame fixed on the upper part of the mounting column, a fan blade mounting plate fixed on the inner side of the circular frame, a fan blade installed inside the fan blade mounting plate, a detection disk threaded on the rear end of the fan blade, and a drag-reducing sleeve fixed on the lower part of the rear end of the fan blade mounting plate.

[0006] Preferably, the bottom end of the mounting bracket is installed on the wind farm foundation via a fixed base, the mounting bracket is kept perpendicular to the horizontal plane, and synchronous motors are installed on the outside of the two sets of lead screws.

[0007] Preferably, the threaded sleeve has a groove on its outer side, and a slider is fixed on the inner side of the cross plate, with the slider movably sleeved inside the groove.

[0008] Preferably, a spring is movably sleeved on the outside of the threaded sleeve, and a float is fitted at the lower end of the mounting sleeve.

[0009] Preferably, a wind vane is mounted on the top of the circular frame via a mounting base, and the wind vane is located at the upper end of the circular frame.

[0010] Preferably, a separation detection probe is installed inside the drag-reducing jacket, and the lower end of the separation detection probe is connected to the detector body via a connecting wire. The separation detection probe faces the detection disk. A protective sleeve is installed inside the drag-reducing jacket and outside the lower end of the separation detection probe. The detector body passes through the circular frame and is located at the rear end of the mounting column.

[0011] Preferably, the lower end of the mounting column is mounted inside the mounting sleeve via a bearing, and an auxiliary bearing is installed between the fan blade mounting plate and the fan blade.

[0012] Compared with existing automatic wind field anemometers, this utility model has the following advantages:

[0013] 1. This automatic wind field anemometer, by controlling the rotation of the lead screw and the threaded movement between the lead screw and the threaded sleeve, can adjust the height of the equipment according to different wind strengths and heights. At the same time, the horizontal plate is movably sleeved outside the threaded sleeve, that is, the height of the horizontal plate outside the threaded sleeve can be adjusted. The equipment can be installed in water, and when the water level rises, it will prevent liquid from flooding the anemometer, thus improving the comprehensiveness of the wind field detection range.

[0014] 2. This automatic wind farm anemometer uses fan blades installed inside a circular frame. After the wind is blown to the outside of the fan blades, the speed of the fan blades is detected by a separate detection probe, which can then be used to detect the wind force. The separate detection probe is installed inside a drag-reducing jacket, and both the detector body and the drag-reducing jacket are installed on the back of the fan blade mounting plate, which reduces wind resistance. This makes the anemometer easier to assemble and reduces interference from the detection equipment on wind force detection. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An automatic wind farm anemometer includes a mounting bracket 1. A lead screw 3 is installed inside the mounting bracket 1, and a threaded sleeve 4 is threaded onto the external thread of the lead screw 3. When the lead screw 3 rotates, the lead screw 3 and the threaded sleeve 4 move threadedly, thereby adjusting the height of the device. A horizontal plate 5 is movably sleeved on the outside of the threaded sleeve 4. A mounting sleeve 8 is fixed in the middle of the horizontal plate 5. A mounting column 10 is movably sleeved inside the mounting sleeve 8. A circular frame 11 is fixed to the upper part of the mounting column 10 and is installed inside the mounting sleeve 8 via the mounting column 10. A fan blade mounting plate 14 is fixed to the inner side of the circular frame 11. Fan blades 16 are installed inside the fan blade mounting plate 14. When air is blown to the outside of the fan blades 16, the fan blades 16 rotate. The wind force can be detected by the different rotation speeds of the fan blades 16. A detection disc 17 is threadedly installed at the rear end of the fan blades 16. A drag-reducing jacket 18 is fixed to the lower part of the rear end of the fan blade mounting plate 14. A separation detection probe 19 is installed inside the drag-reducing jacket 18. The separation detection probe 19 detects the rotation speed of the detection disc 17. The detection device is located inside the drag-reducing jacket 18 to reduce wind resistance, avoid interference with ventilation, and accurately detect the wind force.

[0023] Please see Figure 1The bottom of the mounting bracket 1 is installed on the wind field foundation through the fixed base 2. The mounting bracket 1 is kept perpendicular to the horizontal plane, and the two sets of lead screws 3 are equipped with synchronous motors. After being installed on the wind field foundation through the fixed base 2, the fixed base 2 drives the mounting bracket 1 to be installed vertically. The mounting bracket 1 is equipped with lead screws 3 inside. When the synchronous motors installed on the outside of the lead screws 3 are started, the lead screws 3 and the threaded sleeve 4 move in a threaded motion. The height of the threaded sleeve 4 can be adjusted. During the height adjustment of the threaded sleeve 4, the height of the wind measuring device can be adjusted.

[0024] Please see Figure 2 The threaded sleeve 4 has a groove on its outside. A slider 7 is fixed on the inside of the horizontal plate 5. The slider 7 is movably sleeved inside the groove. The horizontal plate 5 is movably sleeved on the outside of the threaded sleeve 4. The slider 7 is installed on the inside of the horizontal plate 5. That is, the horizontal plate 5 moves up and down outside the threaded sleeve 4. The slider 7 is locked inside the threaded sleeve 4, which improves the stability of the position adjustment between the threaded sleeve 4 and the horizontal plate 5 and avoids the threaded sleeve 4 from rotating, which would cause a height difference.

[0025] Please see Figure 2 The threaded sleeve 4 is externally fitted with a spring 6, and the lower end of the mounting sleeve 8 is fitted with a float 9. Since the equipment is installed outdoors, when rainwater overflows the horizontal plate 5, the buoyancy of the float 9 can drive the height of the horizontal plate 5 to be adjusted, and the elasticity of the spring 6 ensures that the height of the horizontal plate 5 remains stable during the height adjustment.

[0026] Please see Figure 4 A wind vane 13 is mounted on the top of the circular frame 11 via a mounting base 12. The wind vane 13 is located at the top of the circular frame 11 via the mounting base 12. The wind vane 13 is set on the upper part of the mounting column 10. When the wind blows from different directions, the wind vane 13 drives the wind force to split, that is, the wind vane 13 drives the angle of the mounting column 10 to rotate, that is, the mounting column 10 can face the direction of the wind.

[0027] Please see Figure 4 and Figure 5The drag-reducing jacket 18 houses a separation detection probe 19. The lower end of the separation detection probe 19 is connected to the detector body 20 via a connecting wire. The separation detection probe 19 faces the detection disk 17. A protective sleeve is installed inside the drag-reducing jacket 18 and outside the lower end of the separation detection probe 19. The detector body 20 penetrates the circular frame 11 and is located at the rear end of the mounting column 10. The exterior of the drag-reducing jacket 18 has a sloping structure. When the wind blows, the drag-reducing jacket 18 diverts airflow to the side, reducing wind resistance. After being installed inside the fan blade mounting plate 14 via the fan blades 16, the fan blades... A detection disc 17 is installed at the rear end of the blade 16. The detection disc 17 drives the blade 16 to limit its position inside the blade mounting plate 14. A separation detection probe 19 is installed inside the drag-reducing jacket 18. The top of the separation detection probe 19 faces the detection disc 17. The drag-reducing jacket 18 detects the rotational speed of the detection disc 17, and the detector body 20 detects the rotational efficiency of the detection disc 17. By detecting the rotational speed, the wind force can be monitored. At the same time, the monitoring device is located at the rear end of the blade 16, so that the detection device will not interfere with the airflow.

[0028] Please see Figure 3 The lower end of the mounting column 10 is installed inside the mounting sleeve 8 via a bearing. An auxiliary bearing 15 is installed between the fan blade mounting plate 14 and the fan blade 16. The bearing installed at the lower end of the mounting column 10 allows the wind vane 13 to be adjusted when the wind blows. At the same time, the bearing installed inside the mounting sleeve 8 allows the circular frame 11 to rotate, ensuring the flexibility of the circular frame 11 during rotation. The auxiliary bearing 15 installed between the fan blade mounting plate 14 and the fan blade 16 allows the fan blade 16 to rotate when the wind blows. By detecting the rotation speed of the fan blade 16, the wind force can be detected.

[0029] Working principle: In use, the anemometer is installed by fitting the mounting column 10 into the mounting sleeve 8. The equipment is installed in the wind field. Depending on the wind measurement height, the synchronous motor is started to control the threaded movement between the lead screw 3 and the threaded sleeve 4, thereby adjusting the height of the anemometer. When the equipment is not in use, the anemometer can be moved to the lower end. The equipment can also be installed in water. When the liquid overflows the anemometer, the float 9 can float on the water surface. The horizontal plate 5 moves up and down outside the threaded sleeve 4. When the wind blows, the gas is blown to the wind vane 13. The wind vane 13 detects the wind direction and controls the fan blades 16 to face the direction of wind transmission. After the wind blows to the outside of the fan blades 16, the fan blades 16 rotate. The separation detection probe 19 detects the rotation speed of the detection disk 17, thereby detecting and processing the wind force.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
