[0017] (III) Beneficial effects

[0018] The present invention provides a waterproof and pressure-resistant ultrasonic water meter. It has the following beneficial effects:

[0019] (I) The waterproof and pressure-resistant ultrasonic water meter is provided with a protective device. When the device is in use, the protective device is installed on the outside of the meter body, the outer cover wraps the entire device, and the interlayer prevents water from entering the inside of the device. Under the support of the support rod, a gap is always maintained between the outer cover and the meter body. When an external force impacts the outer surface of the outer cover, the outer cover is squeezed and deformed, and the ejector pin on the outer surface of the sealing bottle penetrates into the inside of the sealing bottle. The feed pipe injects foam glue into the inside of the sealing bottle. As the sealing bottle ruptures, the foam glue rushes out and fills the inside of the outer cover. The foam glue then solidifies in contact with the air. It is difficult for external water to penetrate due to the obstruction of the foam glue, which solves the problem that the traditional ultrasonic water meter lacks a protective mechanism on the outside and the outer surface of the water meter is easily squeezed by external force and corroded by water.

[0020] (ii) The waterproof and pressure-resistant ultrasonic water meter is provided with a level measuring device. When the device is in use, water flows into the interior of the connecting pipe from the left end and then is discharged from the right end of the connecting pipe. During this process, the ultrasonic transmitter detects the flow rate. With the impact of the fluid, the flow detection device rotates. Under the push of the liquid, the cover plate and the sealing plate are separated. The limit rod prevents the cover plate from falling off. When the water outlet stops discharging water, the backflowing fluid impacts the cover plate, and the cover plate contacts the sealing plate. The right end of the connecting pipe is closed, which plays a check function and prevents the water hammer effect generated by the backflowing fluid from impacting the water meter and causing damage to the water meter. This solves the problem that the traditional ultrasonic water meter is easily impacted by the backflow of the fluid and causes damage.

[0021] (III) The waterproof and pressure-resistant ultrasonic water meter is provided with a flow detection device. When the device is in use, the fixing ring fixes the top of the ball head rod, and the fluid impacts the outer surface of the turbine plate. Under the action of the arc groove, the turbine plate rotates. Under the action of the buoyancy of the water, the float drives the horizontal axis to float up, and the turbine plate drives the horizontal axis to rotate. The horizontal axis floats up, so that a smaller gap is formed between the turbine plate and the sleeve, which is convenient for the rotation of the horizontal axis and the flow of the fluid. Driven by the horizontal axis, the cam contacts and squeezes the top of the telescopic rod, and the telescopic rod continuously extends and retracts. The water flow is recorded by the extension and retraction of the telescopic rod, which solves the problem of poor detection accuracy of traditional water meters.

[0022] (IV) The waterproof and pressure-resistant ultrasonic water meter is provided with a vertical measuring device. When the device is in use, the fluid impacts the spoiler inside the sealing tube, and the spoiler drives the rotating shaft to rotate. The flow rate of the fluid is recorded by recording the number of rotations of the rotating shaft. During this process, the outer surface of the block contacts the outer surface of the spoiler, and the block continuously moves up and down along the inner surface of the sealing tube. The compression spring is squeezed and released. As the fluid stops moving, the block presses against the spoiler, and the adjusting rod retracts into the inside of the sealing tube. The spoiler and the block block block the inside of the sealing tube, thereby recording the flow rate and playing a certain role in preventing leakage, thus solving the problem of easy leakage of traditional water meters.

[0023] (V) The waterproof and pressure-resistant ultrasonic water meter is provided with a protective device and a meter body. When the equipment is in use, the left end of the horizontal measuring device inside the meter body is the water inlet end, and the right end is the water outlet end. The connecting flange connects the meter body to the external pipeline. When the fluid enters the interior of the horizontal measuring device, the ultrasonic transmitter is activated. Subsequently, the fluid impacts the vertical measuring device to rotate, and the flow is measured for the second time. Then, the flow detection device performs a third measurement. Through multiple measurements, the detection accuracy of the water meter is improved. The protective device wraps the entire meter body to prevent the meter body from direct contact with the outside world, thereby increasing the service life of the water meter and avoiding frequent replacement. This solves the problem that the traditional ultrasonic water meter has a single detection method and is easily affected by the external environment, resulting in large detection accuracy errors and a low service life.
