Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The embodiment of the utility model comprises the following steps:
referring to the attached drawings 1-2, the portable gas leak detector provided with the miniature wind direction indicator comprises a leak detector body 1, a telescopic rod 3, a wind vane 2 and a display screen 4. This internal fixed component that can be used for detecting gas concentration of detector, telescopic link 3 rotates with leak detector body 1 to be connected, fixedly connected with wind vane 2 on the telescopic link 3, and wind vane 2 can the directional direction of blowing, and display screen 4 is used for showing the concentration that the detector body detected.
A gas sensor, a control panel, a buzzer, an LED lamp and a vibrator are fixedly connected in the leak detector body 1, and a display screen 4 is fixedly connected outside the leak detector body 1; the gas sensor, the buzzer, the LED lamp, the vibrator and the display screen 4 are all electrically connected with the control panel. The gas sensor is used for detecting the gas concentration, a 32-bit MCU controller is adopted on the control panel, an analog signal of the gas sensor is converted into a digital signal through a built-in AD converter, the change of the gas concentration and the change of the sensor signal are corresponded through a built-in calibration algorithm (the calibration step is explained in detail in the patent with the application number of 2021109501848, and the details are not repeated here), and the gas concentration is displayed through the display screen 4. After the concentration exceeds a set threshold value, the vibrator vibrates to send out a vibration signal, the LED lamp sends out a light signal, the buzzer sends out a sound signal, and the alarm reminding signals in the forms of sound, light and vibration remind a user that the concentration of the environmental gas on site exceeds the standard.
The leak detector body 1 is provided with a mounting hole; a rotating bearing 5 is fixedly connected in the mounting hole.
The telescopic rod 3 adopts a nested pull rod, the outer side of the uppermost end of the outer layer of the telescopic rod 3 is fixedly connected with the inner ring of the rotating bearing 5, and the upper end of the innermost layer of the telescopic rod 3 is fixedly connected with a wind vane 2; the position of wind vane 2 for leak detector body 1 can be adjusted under the effect of telescopic link 3, extends telescopic link 3 when detecting the wind direction, shortens telescopic link 3 when not using for it is more convenient to use, and does not influence the function of detector body.
