Description

Technical Field

[0001] This utility model relates to the field of wind pressure sensor calibration technology, specifically a wind pressure sensor calibration device. Background Technology

[0002] Before calibrating a wind pressure sensor, calibration equipment needs to be prepared. The calibration process for a wind pressure sensor typically includes zero-point calibration and range calibration. Zero-point calibration must be performed under conditions of no wind pressure and ensure that the wind pressure sensor is in a sealed state, free from the influence of external wind pressure.

[0003] During calibration, the wind pressure in the sealed state is first checked to see if it is zero. If it is not zero, the sealing device needs to be disassembled. Then, the zero-point calibration knob on the wind pressure sensor is turned with a tool, and the sealing test is performed again to check if the wind pressure sensor is zero after calibration. This requires multiple disassembly and assembly of the wind pressure sensor and multiple tests and calibrations, which reduces the calibration efficiency of the wind pressure sensor and makes it impractical.

[0004] Therefore, this utility model provides a wind pressure sensor calibration device. Utility Model Content

The lower end of the inner wall of the fixed cylinder 10 is provided with an internal thread, and the screw 13 is screwed into the inside of the fixed cylinder 10. A rubber column 8 is movably installed at the center of the top of the sealing cover 2 through the through hole 15. With the cooperation of the sealing cover 2 and the rubber ring 3, the wind pressure sensor body 5 can be sealed, and the rubber column 8 can close the through hole 15. At the same time, the zero point adjustment knob 17 can be easily adjusted through the inner hole 16. There is no need to repeatedly disassemble and assemble the wind pressure sensor body 5, which can improve the calibration efficiency of the wind pressure sensor body 5 and has high practicality.

[0026] In this embodiment, fixing holes 6 are provided inside the four corners of the base plate 1. A bottom rubber block 11 is fixedly installed between the front ends of the two rubber rings 3. An arc-shaped groove is provided at the top of the bottom rubber block 11. An elastic rubber block 12 is fixedly installed inside the bottom end of the sealing cover 2 and the front end of the rubber frame 4. An arc-shaped groove is provided at the bottom end of the elastic rubber block 12. The cable of the wind pressure sensor body 5 is snapped into the arc-shaped groove. The fixing holes 6 facilitate the fixing of the device. The rubber rings 3 and the rubber frame 4 cooperate to facilitate the sealing between the sealing cover 2 and the base plate 1. The bottom rubber block 11 and the elastic rubber block 12 can squeeze, fix and seal the cable of the wind pressure sensor body 5. The wind pressure sensor body 5 measures the wind pressure parameters of the closed environment, which facilitates the subsequent zero-point calibration of the wind pressure sensor body 5.

[0027] In this embodiment, the rubber plate 14 is symmetrically fixed on both sides inside the sealing cover 2. One end of the rubber plate 14 has an inclined surface at the position corresponding to the wind pressure sensor body 5. The inclined surface is in close contact with both ends of the wind pressure sensor body 5. A vertical hole is vertically opened inside the rubber plate 14. The fixing cylinder 10 is inserted and installed inside the vertical hole. When the sealing cover 2 and the base plate 1 are inserted, the wind pressure sensor body 5 can be squeezed and fixed by the inclined surface and the rubber plate 14, which can improve the stability of the wind pressure sensor body 5.

[0028] In this embodiment, the through hole 15 is located inside the center of the top of the sealing cover 2. An annular groove is formed on the outer wall of the upper end of the rubber column 8, and the annular groove is installed inside the through hole 15.

A calibration tool 7 is installed inside one side of the top of the base plate 1. By moving the rubber column 8 inside the through hole 15, the through hole 15 can be aligned with the zero-point adjustment knob 17, making it convenient to rotate the zero-point adjustment knob 17 using the calibration tool 7.

The screw 13 is positioned and inserted into the inside of the fixed cylinder 10 and moves downward so that the bottom end of the screw 13 contacts the internal thread. Rotating the screw 13 causes the sealing cover 2 and the rubber plate 14 to move downward through the screwing action of the screw 13 and the internal thread. The rubber plate 14 is pressed against the wind pressure sensor body 5 by the inclined surface. At the same time, the rubber frame 4 is inserted between the two rubber rings 3. The rubber column 8 is moved inside the through hole 15 so that the inner hole 16 is opposite to the zero point adjustment knob 17. Continue to rotate the screw 13, and the bottom end of the rubber column 8 is pressed against the top of the wind pressure sensor body 5. Through the cooperation of the rubber ring 3 and the rubber frame 4, and the bottom rubber block 11 and the elastic rubber block 1 The cooperation of the sealing cover 2 and the rubber plate 14 with the wind pressure sensor body 5 facilitates the sealing between the sealing cover 2 and the base plate 1. At the same time, the sealing cover 2 and the rubber plate 14 compress and fix the wind pressure sensor body 5. The wind pressure sensor body 5 is electrically connected to the data acquisition card via a cable. The data acquisition card is electrically connected to the computer. The computer has parameter software installed on the wind pressure sensor body 5. The computer and the data acquisition card control the wind pressure sensor body 5 to obtain the wind pressure of the device in the sealed state. When the wind pressure is not zero, a calibration tool 7 such as a screwdriver is inserted into the inner hole 16 and the zero point adjustment knob 17 is rotated. At the same time, the software obtains the wind pressure parameters of the wind pressure sensor body 5 and continues to perform zero point calibration until the wind pressure parameters of the wind pressure sensor body 5 are zero. The wind pressure sensor body 5 is then recalibrated. There is no need to repeatedly disassemble and test the wind pressure sensor body 5. The operation is simple and convenient, which can improve the calibration efficiency of the wind pressure sensor body 5 and has high practicality.
