Description

Technical Field

[0001] The present application relates to the field of meteorological measurement, and more specifically, to a wind speed sensor for preventing sandstorms. Background Art

[0002] In many engineering projects, construction machinery often needs to operate in extreme weather conditions, especially in areas that are often hit by strong winds and sandstorms. In these environments, the performance of wind speed sensing equipment is crucial to ensuring the safety and efficiency of construction. However, a common problem is that in areas with strong winds and sand, when it rains, condensation may occur on the wind speed sensing device of the anemometer, which can cause the equipment to run unsmoothly or even get stuck, thus affecting the normal operation of the entire equipment.

[0003] This situation not only reduces construction efficiency, but may also pose a threat to construction site safety. For example, if the wind speed sensor equipment cannot accurately measure the wind speed, then the construction workers cannot accurately assess the impact of wind on the construction structure, which may lead to errors in the construction plan and even, in extreme cases, may cause safety accidents.

[0004] Therefore, there is an urgent need for an anti-sand wind speed sensor to solve the above problems. Summary of the invention

[0005] In order to solve the above technical problems, the present application is proposed. The present application provides a wind speed sensor that is windproof and sandproof, which provides an additional barrier for the wind speed sensor by designing a double-layer stopper between a rotating shell and an upper shell of the wind speed sensor, and also designs a windproof and wind-stopping groove to guide the wind flow. In addition, the design reduces the gap between the rotating part and the sensor body, thereby reducing the chance of wind, sand and moisture entering the sensor.

[0006] Specifically, the present application provides the following technical solution: a wind and sand proof wind speed sensor, comprising: a rotating shell and a wind speed sensor upper shell, wherein a wind-proof and wind-stop groove and a rotating shell stop are fixedly installed on the top of the wind speed sensor upper shell, the wind speed sensor upper shell is movably connected to the rotating shell, and the rotating shell covers the wind-proof and wind-stop groove and the rotating shell stop.

[0007] Preferably, the fitting clearance between the rotating shell and the upper shell of the wind speed sensor is controlled within 0.5 mm.

[0008] Preferably, the upper shell of the wind speed sensor further comprises a rotating shaft, and high-precision bearings are installed at both ends of the rotating shaft. The high-precision bearings are pressed in by a tooling fixture during assembly and fit tightly.

[0009] Preferably, the stopper of the rotating shell is annular and is installed around the end of the rotating shaft.

[0010] Preferably, the windproof and wind-stopping groove is in a threaded shape and is located between the rotating shell and the stop of the rotating shell.

[0011] Preferably, the wind speed sensor for preventing sandstorms further comprises three rotating wind cups, which are hemispherical and fixedly mounted directly above the rotating shell by means of ball-cap nuts.

[0012] Preferably, the rotating shaft drives the rotating wind cup and the rotating shell to rotate together.

[0013] Preferably, the wind speed sensor for preventing wind and sand further comprises a wind speed sensor lower shell, which is installed directly below the wind speed sensor upper shell and connected to the wind speed sensor upper shell via a nut and a sealing ring.

[0014] Compared with the prior art, the present application provides a wind speed sensor that is windproof and sandproof. This design effectively reduces the accumulation of wind and sand and moisture inside the device by reducing the gap between the rotating shell and the upper shell of the wind speed sensor, thereby reducing the equipment jamming caused by condensation or friction, and ensuring the continuous and stable operation of the device. At the same time, the double-layer stop and windproof groove between the rotating shell and the upper shell of the wind speed sensor effectively prevent the intrusion of wind and sand, protect the precision components inside the sensor, and thus improve the stability and reliability of the device in a windy and sandy environment.

[0020] Below, the exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0021] Example:

[0022] like Figure 1 As shown, the cross-sectional view can clearly show the overall structure of the wind speed sensor, so that the reader can clearly see the various key components and their interrelationships.

[0023] like Figure 2 and Figure 3 As shown, the wind speed sensor for preventing sandstorms according to the embodiment of the present application comprises: a fitting gap 1, a windproof and wind-stopping groove 2, a rotating shell stop 3, a high-precision bearing 4, a wind speed sensor lower shell 5, a rotating shell 6, a wind speed sensor upper shell 7, a rotating shaft 8, a ball cover nut 9 and a rotating wind cup 10.

[0024] A windproof and wind-stopping groove 2 and a rotating shell stop 3 are fixedly installed on the top of the wind speed sensor upper shell 7. The wind speed sensor upper shell 7 is movably connected to the rotating shell 6, and the rotating shell 6 covers the windproof and wind-stopping groove 2 and the rotating shell stop 3.

[0025] The matching gap 1 between the rotating shell 6 and the upper shell 7 of the wind speed sensor is controlled within 0.5 mm. This design can effectively prevent large particles of sand and gravel from the external environment from entering the wind speed sensor by reducing the matching gap 1 between the rotating shell 6 and the upper shell 7 of the wind speed sensor, thereby improving the wind and sand protection capability of the wind speed sensor.

[0026] High-precision bearings 4 are installed at both ends of the rotating shaft 8. These bearings are pressed with special jigs during installation, so that the bearings and the shaft fit tightly. This design ensures the stability of the rotation of the rotating wind cup 10, thereby improving the performance and reliability of the wind speed sensor.

[0027] The rotating shell stop 3 is annular and is installed around the end of the rotating shaft 8; the windproof and wind-stopping groove 2 is threaded and is located between the rotating shell 6 and the rotating shell stop 3. When extremely small sand and gravel enter from the matching gap 1 with the wind, the wind and sand will form a reverse cyclone at the windproof and wind-stopping groove 2, causing the heavier sand and gravel to sink, preventing most of the sand and gravel from entering the rotating shell stop 3. When a small part of extremely small sand and gravel enters the rotating shell stop 3, the rotating shell stop 3 will block the entry, thereby improving the wind and sand protection capability of the wind speed sensor.

[0028] The three rotating wind cups 10 of the wind speed sensor are hemispherical and fixedly mounted on the top of the rotating shell 6 by a ball cap nut 9. The rotating shaft 8 can drive the rotating wind cups 10 and the rotating shell 6 to rotate together.

[0029] Among them, the rotating wind cup 10 is the core component of the wind speed sensor, which is used to directly sense the wind speed. The wind blows the rotating wind cup 10 to rotate, and the wind speed is calculated by measuring the rotation speed of the rotating wind cup 10. Moreover, the rotating wind cup 10 is usually made of weather-resistant materials to withstand severe weather conditions, such as strong winds, sandstorms, etc. The ball cap nut 9 is usually used to fix the rotating wind cup 10 above the rotating shell 6 to ensure the accurate position of the rotating wind cup 10 in the wind speed sensor and its stability under strong wind conditions. At the same time, the design of the ball cap nut 9 can make the installation and disassembly of the rotating wind cup 10 simple, which is convenient for maintenance and replacement of the rotating wind cup 10.

[0030] The wind speed sensor lower shell 5 is installed directly below the wind speed sensor upper shell 7, and the two are sealed by threaded connection and tight combination of sealing rings. This design strategy effectively blocks the invasion of wind and sand, thereby improving the protection efficiency of the wind speed sensor against wind and sand.

[0031] In summary, the wind speed sensor for preventing wind and sand according to the embodiment of the present application is explained, which includes: a rotating shell and an upper shell of a wind speed sensor, wherein a windproof and wind-stopping groove and a rotating shell stop are fixedly installed on the top of the upper shell of the wind speed sensor, the upper shell of the wind speed sensor is movably connected to the rotating shell, and the rotating shell covers the windproof and wind-stopping groove and the rotating shell stop. The present invention is reasonably designed and easy to install. It forms a tighter seal through the design of the double-layer stop and windproof and wind-stopping groove of the rotating shell and the upper shell of the wind speed sensor, which improves the stability and accuracy of the wind speed sensor under adverse weather conditions and ensures its long-term reliable operation in a windy and sandy environment.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit of the technical solution of the present invention.
