Utility Model Content

By setting an inner wall cleaning mechanism, the problem of scale, dirt or other pollutants on the inner wall of the water pipe affecting the propagation and reflection of ultrasonic waves is solved. The automatic cleaning function cannot clean the inner wall of the water pipe, resulting in unstable or inaccurate measurement data. Moreover, the dirt on the inner wall of the water pipe will accumulate over time, causing the performance of the water meter to gradually decline. The automatic cleaning function cannot handle the pollution on the inner wall of the water pipe, and the water pipe needs to be manually cleaned or maintained regularly, which increases the cost and workload of maintenance.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an ultrasonic water meter with automatic cleaning function, comprising a water pipe, on which an inner wall cleaning mechanism and a vibration cleaning mechanism are arranged;

[0007] The inner wall cleaning mechanism includes a bidirectional reciprocating screw arranged in the water pipe, a screw sleeve is rotatably sleeved on the outer wall of the bidirectional reciprocating screw, the end of the screw sleeve is fixedly connected to the bidirectional reciprocating screw, and two brush discs are threadedly sleeved on the bidirectional reciprocating screw, and a plurality of bristles are fixedly installed on the outer walls of the two brush discs.

[0008] Furthermore, a rotating shaft 1 is rotatably mounted on the inner wall of the water pipe, and trapezoidal gears are fixedly sleeved on the rotating shaft 1 and the bidirectional reciprocating screw rod respectively, and the two trapezoidal gears are meshed with each other.

[0009] Furthermore, a water meter protection tube is fixedly installed on the outer wall of the water pipe, a motor is arranged on the outer wall of the water meter protection tube, a motor sleeve is fixedly sleeved on the outer wall of the motor, and the end of the motor sleeve is fixedly connected to the water meter protection tube.

[0010] Furthermore, the vibration cleaning mechanism includes vibration cleaning component 1, vibration cleaning component 2, vibration component 3 and vibration component 4. The vibration cleaning component 1 includes a rotating shaft 2 rotatably installed on the inner wall of the water meter protection tube, the end of the rotating shaft 2 is fixedly connected to the output shaft of the motor, and pulleys are fixedly sleeved on the outer walls of the rotating shaft 1 and the rotating shaft 2 respectively.

[0011] Furthermore, the second vibration cleaning component comprises a belt wound around two pulleys, and a collision sleeve is provided on the fixed sleeve on the second rotating shaft.

[0012] Furthermore, the vibration component three includes two trapezoidal slide grooves opened on the inner wall of the water meter protection tube, and the ultrasonic water meter body is slidably mounted on the inner wall of the two trapezoidal slide grooves.

[0013] Furthermore, the vibration component four includes an adapter block fixedly installed at the bottom end of the ultrasonic water meter body, the adapter block is adapted to the collision sleeve, and a plurality of support plates are fixedly installed on the inner wall of the water meter protection tube.

[0014] Furthermore, telescopic rods are fixedly installed on the tops of several of the support plates, springs are wound around several of the telescopic rods, the tops of several of the springs are fixedly connected to the ultrasonic water meter body, the bottoms of several of the springs are fixedly connected to several support plates, and a cover plate is hingedly installed on the top of the water meter protection tube.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up the inner wall cleaning mechanism, when the motor drives the device to vibrate, it will also drive the rotating shaft 1 to rotate through the pulley and the belt. The rotating shaft 1 drives the two-way reciprocating screw on the screw sleeve to rotate through the trapezoidal gear, thereby driving the two brushes to rotate to clean the inner wall of the water pipe, so as to prevent the accumulation of dirt and scale, maintain the smoothness and cleanliness of the inner wall of the water pipe, and help ensure that the transmission and reflection of the ultrasonic signal are not disturbed, thereby improving the measurement accuracy and stability of the water meter, reducing the risk of the water meter being corroded by pollutants, reducing the wear and corrosion of the internal components of the water meter, thereby extending the service life of the water meter, reducing the need for manual cleaning, reducing maintenance costs and workload, and requiring no manual intervention, thereby improving the efficiency of maintenance, reducing water flow resistance and pressure loss, and helping to maintain the stability and operating efficiency of the system. Cleaning the inner wall of the water pipe can ensure smooth water flow and avoid water meter failure or performance degradation caused by dirt blockage;

[0017] 2. By setting a vibration cleaning mechanism, when the environment inside the device is dirty, the motor can be started, and the motor drives the second shaft to rotate, and the second shaft drives the collision sleeve to rotate. When the collision sleeve rotates to the highest point, it will hit the adapter block and drive the ultrasonic water meter body to move to the highest point. The motor continues to rotate, driving the collision sleeve to leave the adapter block, and repeating this process to complete the vibration of the ultrasonic water meter body, so that it can help loosen the dirt on the surface of the water meter, such as dust, sediment, etc., making it easier to clean, helping to keep the surface of the water meter clean, prevent dirt accumulation from affecting the appearance and performance of the water meter, and ensure that the transmission and reflection of the ultrasonic signal are not hindered, thereby maintaining measurement accuracy. Surface dirt will interfere with the propagation path of the ultrasonic signal, resulting in inaccurate measurement data. Vibration cleaning can reduce this interference, reduce the impact of external factors on the water meter, and reduce the possibility of water meter failure.
