Description

Technical Field

[0001] The utility model relates to a generating device, in particular to a wind speed generating device, belonging to the technical field of meteorological detection. Background Art

[0002] Anemometers are mainly used in the HVAC industry, industrial production and other fields. They can be used to measure pipeline wind, exhaust gas emissions, and adjust process production. When calibrating anemometers, it is necessary to simulate the air volume to determine whether the measured value of the anemometer is correct. The simulated air volume requires the use of a wind speed generating device.

[0003] According to the patent number CN212845463U, a low wind speed generating device is disclosed, including a high-power DC motor, a transmission system, a swing arm, a drive controller, a speed detection device and a PC; the transmission system includes a transmission chamber, a spur bevel gear combination, a bevel gear shaft, a rotating shaft, a coupling and a bearing; the swing arm is symmetrically inserted on both sides of the casing, and an ultrasonic anemometer and an anemometer to be calibrated are respectively installed at the end of the swing arm away from the casing.

[0004] During the implementation of the above scheme, the wind speed can be adjusted by changing the motor speed and the arm length. However, during the implementation of the above scheme, it is difficult to protect the surrounding environment during the wind speed generation process. During the wind speed generation process, when the device runs at high speed, it is easy to be drawn into small particles such as stones and leaves from the outside, causing the rotation to be affected. This will not only reduce the service life of the device, but also the splashing stones and other particles will pose a safety threat to the surrounding environment and testers. For this reason, we provide a wind speed generating device to solve the above problems. Utility Model Content

[0026] The embodiment of the utility model provides a wind speed generating device.

[0027] See also Figure 1 and Figure 2 , including a fixing frame 1, the top of which is fixedly connected with a rectifier duct 2, the fixing frame 1 provides support for the use of the rectifier duct 2 to prevent the rectifier duct 2 from shaking during operation, the rectifier duct 2 can protect the operation of the fan 4, reduce the external influence on the device during operation, and avoid the fan 4 causing safety hazards to the surrounding environment and testers during operation.

[0028] See also Figure 2 The rectifier duct 2 is internally connected to a rotating rod 3, one end of which is fixedly connected to a fan 4. The rotation of the rotating rod 3 can drive the fan 4 to rotate. The rotation of the fan 4 can form a wind flow inside the rectifier duct 2, thereby simulating the wind volume to determine whether the measurement value of the anemometer 8 to be calibrated is correct.

[0029] Please refer again Figure 1 and Figure 2The outer surface of the rectifying duct 2 is provided with ventilation holes 5. Through the setting of the ventilation holes 5, small particles such as stones and leaves in the external environment can be blocked without affecting the ventilation effect of the rectifying duct 2, thereby preventing small particles from being drawn into the wind speed generating device and causing damage to the generating device, thereby ensuring the normal operation of the device.

[0030] The outer surface of the rectifying duct 2 is fixedly connected to two guide pipes 6, and a clamping mechanism 7 is provided on the outside of each guide pipe 6. Through the setting of the two guide pipes 6, the wind flow generated by the fan 4 can be transported in equal amounts, so that the wind volume experienced by the anemometer 8 to be calibrated and the ultrasonic anemometer 9 is consistent, which is convenient for calibrating the measurement value of the anemometer 8 to be calibrated.

[0031] The middle parts of the two clamping mechanisms 7 are respectively provided with an anemometer to be calibrated 8 and an ultrasonic anemometer 9. The anemometer to be calibrated 8 and the ultrasonic anemometer 9 are both prior arts and will not be described in detail in this application. By setting the ultrasonic anemometer 9, the measured values ​​can be compared with those of the anemometer to be calibrated 8, so as to calibrate the measured data of the anemometer to be calibrated 8 more accurately.

[0032] See also Figure 1 A high-power DC motor 10 is arranged outside the rectifier duct 2, and an output shaft 11 is connected to the internal rotation of the high-power DC motor 10. The high-power DC motor 10 is a prior art and will not be described in detail in this application. Through the arrangement of the high-power DC motor 10, the high-power DC motor 10 can drive the output shaft 11 to rotate when it is started. The output shaft 11 is fixedly connected to one end of the rotating rod 3 through a latch. The rotation of the output shaft 11 can drive the rotating rod 3 to rotate, thereby providing power for the wind speed generation process.

[0033] A fixed base 12 is arranged outside the fixing frame 1, and the fixed base 12 is fixedly connected to the high-power DC motor 10. The fixed base 12 provides support for the high-power DC motor 10, so that the high-power DC motor 10 can remain stable during operation and prevent external vibrations from affecting the normal operation of the high-power DC motor 10.

[0034] A PC 13 is arranged outside the high-power DC motor 10. The PC 13 is a prior art and will not be described in detail in this application. The PC 13 is electrically connected to the high-power DC motor 10 via a data cable. Through the setting of the PC 13, the tester first sets the wind speed value to be calibrated on the PC 13, and converts the set wind speed value into the required speed of the high-power DC motor 10 through calculation by the PC 13. Then, the high-power DC motor 10 is driven to rotate at a specific speed via the data cable control. The wind speed measured by the anemometer 8 to be calibrated is compared with the wind speed set by the PC 13, and the anemometer 8 to be calibrated can be further calibrated.

[0035] See also Figure 1 and Figure 3 The clamping mechanism 7 includes a connecting frame 701 fixedly connected to the guide pipe 6, and one end of the connecting frame 701 is fixedly connected to a clamping platform 702. Through the setting of the connecting frame 701 and the clamping platform 702, support is provided for the clamping mechanism 7 to clamp the anemometer 8 to be calibrated and the ultrasonic anemometer 9, so that the anemometer 8 to be calibrated and the ultrasonic anemometer 9 remain stable during the wind speed measurement process to avoid shaking affecting the measurement results.

[0036] The internal rotation of the clamping platform 702 is connected with a bidirectional screw 703, which is a prior art. Half of the screw rotates to the left and half to the right. When the bidirectional screw 703 rotates, it can drive the two ends of the screw to rotate in different directions, thereby driving the two threaded sliders 704 to slide towards or in the opposite direction.

[0037] See also Figure 1 , Figure 3 and Figure 4 The outer surface of the bidirectional screw 703 is threadedly connected to two threaded sliders 704, each threaded slider 704 is slidably connected to the clamping platform 702, and a knob is installed at one end of the bidirectional screw 703. When the knob is turned, the bidirectional screw 703 will also rotate accordingly. The rotation of the bidirectional screw 703 can drive the two threaded sliders 704 to slide toward each other, thereby driving the fixed clamping claws 706 to clamp the anemometer 8 to be calibrated, so that the clamping mechanism 7 can clamp anemometers of different sizes and types, providing the applicability of the device.

[0038] The outer surface of each threaded slider 704 is fixedly connected to a connecting rod 705, and one end of each connecting rod 705 is fixedly connected to a fixed clamping claw 706. The shapes and sizes of the fixed clamping claw 706 and the movable clamping claw 708 are produced according to the size of the actual anemometer. This application is only for style reference and no specific production standard is made. Buffer pads are installed on the inner walls of the fixed clamping claw 706 and the movable clamping claw 708, which can not only increase the clamping friction, but also prevent the anemometer 8 to be calibrated and the ultrasonic anemometer 9 from being damaged during the clamping process.

[0039] Each fixed clamping claw 706 is rotatably connected to a one-way threaded rod 707, and a rotating wheel is installed at one end of the one-way threaded rod 707. The rotation of the rotating wheel can drive the one-way threaded rod 707 to rotate, and the rotation of the one-way threaded rod 707 can drive the movable clamping claw 708 to slide on the outer surface of the fixed clamping claw 706, thereby clamping or unclamping the anemometer 8 or ultrasonic anemometer 9 to be calibrated.

[0040] The outer surface of each one-way threaded rod 707 is threadedly connected with a mobile clamping claw 708, and the two mobile clamping claws 708 are respectively slidably connected to the corresponding fixed clamping claws 706. The sliding of the mobile clamping claws 708 can adjust the relative distance between the mobile clamping claws 708 and the fixed clamping claws 706, so as to clamp the anemometer 8 or ultrasonic anemometer 9 to be calibrated, so that the anemometer can remain stable during the wind speed measurement process, thereby improving the measurement accuracy of the anemometer.

[0041] When the utility model is in use, the surveying personnel first place the anemometer to be calibrated 8 and the ultrasonic anemometer 9 in the two fixed clamping claws 706 respectively, and then rotate the wheel at one end of the one-way threaded rod 707 and the knob at one end of the two-way screw rod 703, so that the clamping mechanism 7 can stably clamp the anemometer to be calibrated 8 and the ultrasonic anemometer 9, and then set the wind speed value to be calibrated on the PC 13, the PC 13 drives the high-power DC motor 10 to start at a specific speed, the high-power DC motor 10 starts to drive the output shaft 11 to rotate, the output shaft 11 rotates to drive the rotating rod 3 to rotate, the rotating rod 3 rotates to drive the fan 4 to rotate, so that a wind flow is formed inside the rectifying duct 2, after the diversion of the guide pipe 6, the anemometer to be calibrated 8 and the ultrasonic anemometer 9 start to measure the wind speed of the same air volume, after the measurement is completed, the staff compares the wind speed value measured by the anemometer to be calibrated 8 with the value set by the PC 13 and the value measured by the ultrasonic anemometer 9, and it can be judged whether the measured value of the anemometer is correct.
