[0022] Specific operation is as follows, since lead screw one 202 and lead screw two 206 are divided into right-handed and left-handed according to direction, servo motor 201 provides rotating force for lead screw one 202 and synchronous pulley one 203, power is transmitted by synchronous belt 204 and synchronous pulley one 203 and synchronous pulley two 205, so that lead screw nut one 207 and lead screw nut two 211 move horizontally outside lead screw one 202 and lead screw two 206 respectively, so as to change the support angle of support rod one 209 and support rod two 213 to lifting plate 210, so that lifting plate 210 slides up and down outside slide rod 214, which is convenient for realizing gas detection at different heights in the environment.

[0023] As Figure 1 and Figure 3As shown, a drive motor 3 is installed in the groove at the top of the lifting plate 210, and the output end of the drive motor 3 is connected to a drive shaft 4. A drive gear 5 is sleeved on the outside of the drive shaft 4, and a driven gear 6 is connected to the outside of the drive gear 5.

[0024] The specific operation is as follows: when the drive motor 3 drives the drive shaft 4 to rotate, the small-diameter drive gear 5 drives the large-diameter driven gear 6 to achieve a certain deceleration purpose, thereby making the mounting plate 8 and the ultrasonic leak detector 9 rotate stably. By adjusting the direction of the ultrasonic leak detector 9, a wider range of detection can be achieved.

[0025] In summary, when using this natural gas station leak detection device, the entire device is first moved to a suitable position within the natural gas station using the casters 10. When the height of the ultrasonic leak detector 9 needs to be adjusted, the servo motor 201 is started, which drives the lead screw 202 and the synchronous pulley 203 to rotate. The synchronous belt 204 meshes with the synchronous pulleys 203 and 205 to transmit power, enabling the lead screw nut 207 and the lead screw nut 211 to move horizontally outside the lead screw 202 and the lead screw 206, respectively. The rotating support rods 209 and 213 generate an upward supporting force on the lifting plate 210, making the height of the ultrasonic leak detector 9 adjustable to meet the needs of gas detection at different heights within the natural gas station. The sliding rod 214 contacts the groove on the surface of the lifting plate 210 and forms a guiding effect, ensuring that the lifting plate 210 remains vertical.

[0026] Next, start the drive motor 3. The drive motor 3 drives the drive shaft 4 and the drive gear 5 to rotate. The small diameter drive gear 5 drives the large diameter driven gear 6 to achieve a certain deceleration purpose, so that the transmission shaft 7, the mounting plate 8 and the ultrasonic leak detector 9 rotate stably, thereby changing the detection range in the horizontal direction and improving the accuracy and timeliness of the device in detecting natural gas leaks inside the natural gas station.
