Description

Technical Field

[0001] This utility model relates to the technical field of meteorological wind speed and direction measuring instruments, and in particular to a foldable track-type on-site verification instrument for wind direction and speed. Background Technology

[0002] As a standard calibration instrument, the wind direction and speed testing instrument can perform on-site calibration of wind elements of regional automatic weather stations currently in use in various places.

[0003] Currently, because the instrument heights of different models of wind direction and speed sensors vary, when the instrument height is too high, multiple staff members are needed to lay down the wind direction and speed sensor during calibration before checking it. Therefore, checking the wind direction and speed sensor not only requires a lot of manpower but also takes a long time to lay down and re-erect the wind mast. The current method for checking wind direction and speed sensors is far from meeting the needs of modernizing meteorological operations and promoting high-quality meteorological development.

[0021] Example 1

[0022] Please refer to the reference. Figure 1-3This application provides a foldable track-type wind direction and speed field verification instrument, including a track 1, a first clamp 2, a second clamp 3, a lifting mechanism 4, a wind direction standard sensor 5, a wind speed standard sensor 6, and a laser rangefinder sensor 7. The track 1 has at least two sections, and a limiting device 9 is provided between adjacent sections of the track 1. The limiting device 9 includes a first limiting plate 901 and a second limiting plate 902. The first limiting plate 901 is fixedly connected to the output shaft of a folding motor 8, and the second limiting plate 902 is rotatably connected to the folding motor 8. The first limiting plate 901 and the second limiting plate 902 are folded or... When unfolded, the bottom track 1 has two first clamps 2 on its back, the top track 1 has a second clamp 3 on its back, the front of the track 1 has slide rails 10 on both sides, the bottom of the track 1 has a third limiting plate 11, the slide rails 10 have sliders 12 that cooperate with the slide rails 10, the sliders 12 are fixedly connected to the slide plate 13, the slide plate 13 is fixedly installed with the lifting mechanism 4, the lifting mechanism 4 is sleeved with the crossbar 14, the crossbar 14 is fixedly connected to the wind direction standard sensor 5 and the wind speed standard sensor 6 through the connecting rod 22, and the connecting rod 22 is equipped with a laser rangefinder sensor 7.

[0023] The track 1 of this application is initially folded for easy storage and transport of the verification instrument. The track 1 is fixed to the wind mast equipped with wind direction and speed sensors via the first clamp 2. After fixing, the folding motor 8 starts, driving the second limiting plate 902 to rotate and close with the first limiting plate 901, causing adjacent sections of track 1 to unfold into a straight track 1. After all the folded track 1 sections are unfolded, the second clamp 3 at the top of track 1 is fixed to the wind mast, improving the stability and fixation of track 1. The connecting rod 22 and the crossbar 14, equipped with the wind direction standard sensor 5 and the wind speed standard sensor 6, are installed onto the lifting mechanism 4. The crossbar 14 is sleeved with the lifting mechanism 4 for easy installation of the verification instrument. The lifting mechanism 4, via the slide plate 13 and slider 12, moves the wind direction standard sensor 5 and wind speed standard sensor 6 along the slide rail 10 until they rise to the height of the wind direction and wind speed sensors being checked. Finally, the laser rangefinder 7 adjusts the height of the crossbar 14 carrying the wind direction and wind speed standard sensors 5 and 6 to ensure they are at the same height as the sensors being checked. Data from both sensors is then transmitted to the processor for comparison. This verification device facilitates the checking of wind direction and wind speed sensors located at higher positions, reducing manpower consumption and improving verification efficiency. The third limit plate 11 provides support for the slide plate 13.

[0024] Specifically, a connecting plate 15 is provided on the top back of the track 1. Control motors 16 are fixedly installed on both sides of the connecting plate 15. The control motors 16 are perpendicular to the second clamp 3. The second clamp 3 includes a first clamp body 301 and a second clamp body 302. The output shafts of the two control motors 16 are fixedly connected to the first clamp body 301 and the second clamp body 302, respectively. By controlling the rotation of the first clamp body 301 and the second clamp body 302 of the second clamp 3 through the control motors 16, the second clamp 3 can be opened or closed. This facilitates the operator in controlling the second clamp 3 to fix the track 1 to the wind tower. After use, opening the second clamp 3 makes it easy to fold and store the track 1. The connecting plate 15 serves to fix the control motors 16 and improve the stability of the second clamp 3.

[0025] Specifically, the lifting mechanism 4 includes a lifting motor 401, a first gear 402, and a rack 403. The first gear 402 is mounted on the output shaft of the lifting motor 401, and the rack 403 is fixedly installed in the middle of the slide rail 10. The first gear 402 and the rack 403 mesh with each other. The lifting motor 401 and the gear 402, through the rack 403, complete the rising and falling motion of the slider 12 within the track 1. At the same time, it drives the wind direction standard sensor 5 and the wind speed standard sensor 6 on the slide plate 13 to move on the slide rail 10, reducing manpower consumption and improving verification efficiency.

[0026] Specifically, the end of the crossbar 14 is provided with a square box 17, and the square box 17 is provided with a gear set 19 arranged along the inner bottom surface. The gear set 19 includes a second gear 1901, a third gear 1902, and a third and fourth gear 1903. The gears of the gear set 19 mesh with each other. The second gear 1901 is fixedly connected to the output shaft of the rotary motor 18. The third gear 1902 and the fourth gear 1903 are fixedly connected to the wind direction standard sensor 5 and the wind speed standard sensor 6 respectively through the connecting rod 22. The rotary motor 18 and the gear set 19 are used to control the opening or closing of the wind direction standard sensor 5 and the wind speed standard sensor 6. To prevent the cable from obstructing the connecting rod 22 during the lifting process, the second gear 1901 is rotated by the rotary motor 18 before the lifting action is performed. At the same time, through the meshing action between the gears 402, the wind direction standard sensor 5 and the wind speed standard sensor 6 connected to the third gear 1902 and the fourth gear 1903 are folded and rotated 80 degrees. When the square box 17 rises to the designated height, the rotary motor 18 and the gear set 19 open the connecting rod 22 carrying the wind direction standard sensor 5 and the wind speed standard sensor 6, ensuring that the wind direction standard sensor 5 and the wind speed standard sensor are aligned with the wind direction and wind speed sensors being checked, thereby improving the accuracy of the check data.

[0027] Specifically, the upper track 1 of two adjacent sections is 20cm shorter than the lower track 1. The 20cm difference between adjacent track 1 sections can prevent the track 1 from bumping during folding, and the reserved space after folding makes it convenient to place the slide plate 13 on the track 1, thus improving the practicality of the instrument.

[0028] Example 2

[0029] Please refer to the reference. Figure 1-3 The difference between this embodiment and Embodiment 1 is that the slide plate 13 is equipped with an electric push rod 20, which is fixedly connected to the side of the square box 17. The function of the electric push rod 20 is to ensure that the distance between the wind direction standard sensor 5 and the wind speed standard sensor 6 and the wind direction and wind speed sensors being checked will not be damaged by collision, and at the same time, to ensure that both are under the same measured environmental conditions, thereby improving the accuracy of the verification data.

[0030] Specifically, the lifting motor 401 is fixedly connected to the encoder 21. The encoder 21 determines the height of the wind direction and speed sensor being checked, ensuring that the height of the wind direction and speed sensor meets the wind measurement height requirements, thereby improving the accuracy of the check data.

[0031] In the above embodiments, the foldable track-mounted wind direction and speed field verification instrument can be assembled with different numbers of sections according to the height of the wind direction and speed sensors being verified. Simultaneously, the foldable track-mounted wind direction and speed field verification instrument and the automatic weather station monitor wind direction and speed in the same space, obtaining standard wind direction and speed data and current wind direction and speed data. Based on the standard and current wind direction and speed data, it is determined whether the wind direction and speed data measuring device is malfunctioning. This not only eliminates the need to disassemble the wind mast carrying the sensors but also allows the automatic weather station to continue monitoring the weather, thus ensuring no meteorological data is lost.

[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
