[0002] Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed when the ultrasonic sound beam propagates downstream and upstream in water, analyzes and processes the water flow rate, and further calculates the water flow rate.

[0003] Existing ultrasonic water meters are divided into two types according to the arrangement of the sound channel: the ultrasonic propagation direction of the ultrasonic water meter is crossed with the water flow direction at a certain angle; the reflective ultrasonic water meter will weaken the ultrasonic energy by reflecting the ultrasonic wave through the reflector, but the reflective element of the existing reflective ultrasonic water meter is easily affected by the deposition of scale, which weakens the ultrasonic energy. The smaller the water flow, the lower the measurement accuracy. Summary of the invention

A driven gear 7 is rotationally connected to the inside of the fixed pipe 4. The driving gear 6 is meshingly connected to the driven gear 7, and the driven gear 7 is fixedly connected to the reflective sheet 8. The reflective sheet 8 can be rotated by the first driving device 5 to adjust the reflective sheet 8 to a suitable working angle, and both the front and back sides of the reflective sheet 8 can be used as reflective surfaces.

[0033] Embodiment three:

[0034] See also Figure 2 and Figure 4 A waterproof part 17 is embedded in the bottom of the fixed pipe 4. The waterproof part 17 is composed of a waterproof bearing 1701 and a sealing ring 1702. The sealing ring 1702 is fixedly connected to the inner side of the waterproof bearing 1701. The sliding rod 9 is slidably connected with the sealing ring 1702. The waterproof bearing 1701 allows the sliding rod 9 to rotate. The sealing ring 1702 and the sliding rod 9 fit tightly, thereby improving the sealing performance of the waterproof part 17.

[0035] Embodiment 4:

[0036] See also Figure 2 A drain port 12 is provided on the bottom surface wall of the fixed pipe 4, and a valve 13 is installed at the bottom of the drain port 12. When the valve 13 is opened during cleaning, sewage can flow out of the pipe, thereby reducing scale pollution.

[0037] Embodiment five:

[0038] See also Figure 1 and Figure 2 The fixed pipe 4 is made of glass, which makes it convenient for people to observe the angle of the reflective sheet 8 and the scale on the surface of the reflective sheet 8.

[0039] Embodiment six:

[0040] See also Figure 1 and Figure 2 The controller 3 is electrically connected to the ultrasonic water meter body 2, the first drive device 5, the electric push rod 14 and the second drive device 16. The device is controlled by the controller 3, which facilitates centralized operation and control of the device.

[0041] Working principle: When in use, supply mains electricity to the electrical equipment of the device. First, install the ultrasonic water meter body 2, start the first drive device 5 to drive the drive gear 6 to rotate, the drive gear 6 drives the driven gear 7 to rotate, and then drives the reflector 8 to rotate to a suitable angle for ultrasonic reflection. After working for a period of time, check whether there is scale precipitation on the upper surface of the reflector 8 through the fixed pipe 4 made of glass. When there is a lot of scale precipitation, start the first drive device 5 to drive the reflector 8 to rotate 180° so that the back of the reflector 8 can continue to work, thereby extending the use time of the water meter; secondly, after a lot of scale is deposited on both sides of the reflector 8, turn off the ultrasonic water meter body 2 through the controller 3, start the first drive device 5 to rotate the reflector 8 to a horizontal position, and then start the electric push rod 14 to retract and lift the mounting plate 15, and install it. The plate 15 can drive the second driving device 16 and the slide bar 9 to rise until the cleaning brush 11 fits the bottom of the reflective sheet 8, and then the second driving device 16 is started to drive the slide bar 9 to rotate, and further rotate the cleaning brush 11, and at the same time open the valve 13. The rotation of the cleaning brush 11 can remove the scale on the surface of the reflective sheet 8, and the sewage contaminated by the scale can be discharged from the drain port 12. The rotation of the slide bar 9 relies on the waterproof bearing 1701, and the outer wall of the slide bar 9 is tightly fitted with the sealing ring 1702 when the slide bar 9 slides up and down, thereby avoiding the problem of water leakage. Through the above steps, both sides of the reflective sheet 8 can be used for reflection work, which prolongs the working time, and the scale deposited on both sides of the reflective sheet 8 can be removed by the cleaning brush 11, and then cleaning can be performed without disassembling the water meter, which helps to improve work efficiency and help to improve the detection accuracy of the water meter.
