Description

Technical Field

[0001] This utility model specifically relates to a wind speed and direction sensor with a streamlined windproof cover structure. Background Technology

[0002] Wind speed and direction sensors are critical measurement devices in meteorological monitoring, environmental observation, aerospace, wind power generation, and industrial safety. Their accuracy and reliability directly affect data quality and system decision-making. Traditional wind speed and direction sensors typically consist of sensing components such as wind cups, wind vanes, or ultrasonic probes. These components are directly exposed to the natural environment and are susceptible to interference from strong winds, rain, snow accumulation, dust, and turbulence, leading to increased measurement errors, accelerated equipment wear, and even structural damage.

[0003] To reduce environmental interference, existing technologies often employ windproof structures to protect the sensor's sensing components. Common windproof structures are mostly grid-like, louvered, or simple porous structures, which reduce direct wind pressure and lateral turbulence through physical barriers. Traditional windproof structures often use right-angled or acute-angled edges, which can easily generate eddies and airflow stripping in high-speed airflows, leading to turbulent flow fields around the sensor and affecting the instantaneous accuracy and stability of wind speed and direction measurements. Grid or louver structures have many gaps, which can easily accumulate impurities in rain, snow, and dusty environments, not only increasing wind resistance but also potentially blocking airflow channels, requiring frequent maintenance and cleaning after long-term use.

[0004] Therefore, it is necessary to invent a wind speed and direction sensor with a streamlined windproof cover structure to solve the above problems. Utility Model Content

[0005] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a wind speed and direction sensor with a streamlined windproof cover structure.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-6 A wind speed and direction sensor with a streamlined windproof cover structure is shown, including a wind speed and wind vane 1, a connecting pipe 11 extending from the bottom of the wind speed and wind vane 1, a support rod 12 provided at the bottom of the connecting pipe 11, a sensor 2 fixed to the outer wall of the support rod 12, a windproof cover assembly 3 provided outside the sensor 2, and the windproof cover assembly 3 mounted on the support rod 12. Specifically, the support rod 12 has a wiring hole 13 inside, a moving groove 14 on both sides of the support rod 12, a positioning groove 15 on the outer wall of the support rod 12 behind the moving groove 14, and a slot 16 on the front of the support rod 12, which is connected to the wiring hole 13. Specifically, the windproof cover assembly 3 includes a windproof cover 31. The outer wall of the windproof cover 31 is arc-shaped, and the inner side of the windproof cover 31 is provided with a moving strip 32 that matches the moving groove 14. The front of the windproof cover 31 is provided with a mounting groove 33, which matches and corresponds to the slot 16. A cover plate 34 is installed in the mounting groove 33 and is inserted from the mounting groove 33 into the slot 16. The rear opening of the windproof cover 31 is provided with a fixing area 35, and a fixing plate 36 is provided in the fixing area 35. The fixing plate 36 is inserted from the positioning groove 15 and fixes the windproof cover 31. The outer wall of the support rod 12 is located at the bottom of the windproof cover 31 and a base plate 37 is also fixed thereon. The fixing plate 36 is placed on the top of the base plate 37.

[0018] Specifically, the wind shield 31 is installed on the top of the base plate 37. The top side of the wind shield 31 is provided with an insertion hole 311, and a positioning pin 38 is inserted into the insertion hole 311. The end of the cover plate 34 is provided with a fixing hole 341 that matches the insertion hole 311. The positioning pin 38 is inserted into the insertion hole 311 and fixed in the fixing hole 341.

[0019] Specifically, the cover plate 34 is sized to match the top size of the windshield 31.

[0020] Specifically, the fixed area 35 is provided with positioning and locking grooves 351 on both sides, and the fixed plate 36 is provided with locking strips 361 that match the positioning and locking grooves 351 on both sides. The ends of the positioning and locking grooves 351 and the locking strips 361 are both arc-shaped. The fixed plate 36 is provided with a positioning arc plate 362 that matches the positioning groove 15 on the inner side. The positioning arc plate 362 and the positioning groove 15 are both arc-shaped in cross section.

[0021] Specifically, the bottom of the fixing plate 36 extends with an insert 363, and the top of the base plate 37 is provided with a positioning hole 371 that matches the insert 363.

[0022] Specifically, a pull ring 364 is provided on the fixing plate 36.

[0023] In this embodiment, the connecting pipe 11 at the bottom of the wind speed and vane indicator 1 is pre-fixed to the support rod 12 to ensure that the connection is secure and without looseness. The sensor 2 is fixedly installed at a preset position on the outer wall of the support rod 12. Then, the wires of the sensor 2 are passed through the moving slots 14 on both sides of the support rod 12 and introduced into the wire hole 13 inside the support rod 12 to complete the concealed arrangement of the wires.

[0024] Specifically, take the windproof cover 31, align the inner movable strip 32 with the movable groove 14 on the outer wall of the support rod 12, and slide it downwards along the extension direction of the movable groove 14 until the bottom of the windproof cover 31 is attached to the top of the pre-fixed base plate 37 on the outer wall of the support rod 12. At this time, the mounting groove 33 on the front of the windproof cover 31 corresponds precisely to the slot 16 on the front of the support rod 12, and the fixing area 35 at the rear of the windproof cover 31 is aligned with the positioning groove 15 on the rear side of the support rod 12. Insert the cover plate 34 into the mounting groove 33 of the windproof cover 31 and extend it into the slot 16 of the support rod 12. Use the cover plate 34 to seal the mounting groove 33 and the slot 16. At the same time, the size of the cover plate 34 matches the top size of the windproof cover 31 to ensure the sealing of the top of the windproof cover 31. Take the positioning pin 38 and insert it into the insertion hole 311 on one side of the top of the windproof cover 31, and let its end extend into the fixing hole 341 at the end of the cover plate 34 to complete the relative fixation of the cover plate 34 and the windproof cover 31, and prevent the cover plate 34 from loosening.

[0025] Specifically, take the fixing plate 36 and align the locking strips 361 on both sides of it with the positioning locking grooves 351 on both sides of the fixing area 35. Since the positioning locking grooves 351 and the ends of the locking strips 361 are both arc-shaped, the insertion resistance can be reduced, facilitating quick alignment. Push the fixing plate 36 so that the positioning arc plate 362 on the inner side of the fixing plate 36 is embedded into the positioning groove 15 of the support rod 12. The positioning arc plate 362 and the positioning groove 15 are both arc-shaped, which can improve the fit between the two and enhance the positioning stability. Continue to press down the fixing plate 36 so that the insert strip 363 extending from its bottom is inserted into the positioning hole 371 at the top of the base plate 37, completing the fixing of the fixing plate 36 and the base plate 37. At this time, the fixing plate 36 presses the tail fixing area 35 of the windproof cover 31 tightly onto the support rod 12, realizing the overall reinforcement of the windproof cover 31. To remove the windproof cover 31, pull the pull ring 364 on the fixing plate 36 to remove the fixing plate 36 from the fixing area 35 and the positioning groove 15, then pull out the positioning pin 38, remove the cover plate 34, and finally slide the windproof cover 31 upwards to complete the removal.

[0026] Specifically, after the installation of the windproof cover assembly is completed, the wind speed and direction sensor can be placed in the environment to be tested. The wind speed and direction are sensed by the wind speed and direction indicator 1, the sensor 2 is responsible for signal acquisition and transmission, and the windproof cover 31 protects the sensor 2.

[0027] In this embodiment, the outer wall of the windproof cover 31 has an arc-shaped streamlined structure, which can effectively reduce wind resistance and reduce the impact of strong wind on the windproof cover 31. At the same time, it can block external impurities such as wind, sand, rain and snow from directly contacting the sensor 2, avoiding damage or contamination to the sensor 2 and extending the service life of the sensor.

[0028] In this embodiment, the windproof cover 31 is initially positioned by the sliding cooperation between the moving strip 32 and the moving groove 14, and then reinforced by the double fixing of the fixing plate 36 and the positioning pin 38. The entire installation process does not require complicated tools; when disassembling, it is only necessary to pull the pull ring 364 to remove the fixing plate 36, and then remove the positioning pin 38 and the cover plate 34 in sequence, which facilitates the later inspection and maintenance of the sensor 2.

[0029] In this embodiment, the support rod 12 is provided with a wiring hole 13, in which the wiring of the sensor 2 can be hidden to prevent the wiring from being exposed to the wind and sun or being pulled by external forces. At the same time, the moving groove 14 provides a channel for the wiring to pass through, ensuring the stability and safety of the wiring connection.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
