[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0023] Reference Figure 1-4 As shown, an ultrasonic water meter for preventing clogging is provided, a filter assembly 10 is provided at the front end of a first pipe 1, the filter assembly 10 and the outer surface of the first pipe 1 are installed because a second bolt 11 penetrates the outer surface thereof, the outer portion of the filter assembly 10 is provided as an outer ring 101, a rotating shaft 12 is provided on one side of the outer ring 101, a handle 13 is provided on the axial surface of the rotating shaft 12, the handle 13 is used and rotated by an external force, so that a limiting block 102 squeezes a first mounting ring 103 and a second mounting ring 104 are combined, the limiting block 102 is fixedly installed on the inner side of the outer ring 101, the first mounting ring 103 is provided on the inner side of the outer ring 101, and the inner side of the outer ring 101 A second mounting ring 104 is also installed on the side, and mounting grooves are arranged on the outer sides of the first mounting ring 103 and the second mounting ring 104, and the outer surface of the limit block 102 is inserted into the mounting grooves of the first mounting ring 103 and the second mounting ring 104, and a boss 105 is arranged at the opposite end of the first mounting ring 103 and the second mounting ring 104. After being squeezed by external force, the boss 105 enters the slot 106, and the limit block 102 is clamped in the mounting grooves of the first mounting ring 103 and the second mounting ring 104, thereby achieving the purpose of fixing the above components, and a slot 106 is opened at the other end of the first mounting ring 103 and the second mounting ring 104.
[0024] Furthermore, a water meter body 3 is installed on one side of the second pipe 2. When the water flows through the venturi tube 15, the flow rate will change, resulting in a change in the pressure difference between the front and rear ends of the venturi tube 15. The water meter body 3 measures the pressure difference between the front and rear ends of the venturi tube 15 and combines the geometric shape of the venturi tube 15 to calculate the water flow rate and thus better detect whether a blockage occurs. A mounting plate 16 is fixedly installed on one side of the second pipe 2, and a wireless network component 4 is installed on the upper surface of the mounting plate 16.
[0025] Furthermore, a venturi tube 15 is provided inside the first pipe 1, and the second pressure sensor 14 and the first pressure sensor 9 are respectively provided at the front and rear ends of the venturi tube 15. If the blockage is small, the water flow velocity does not drop significantly, and the water meter body 3 may not be able to detect it, or the water flow turbulence is serious, and the ultrasonic signal may be interfered with, resulting in the water meter body 3 being unable to accurately measure the water flow velocity. At this time, the fluid velocity can be calculated by measuring the pressure difference between the front and rear ends of the venturi 15. When the filter assembly 10 is blocked, the pressure difference between the front and rear ends of the venturi tube 15 will change. The change in the pressure difference can be monitored by the first pressure sensor 9 and the second pressure sensor 14, and the blockage can be detected. Occurs, the water meter body 3 and multiple groups of pressure sensors assist each other and have the advantages of more accurate blockage detection, earlier blockage warning and more comprehensive water flow monitoring compared to traditional equipment. A second pressure sensor 14 is installed on one side of the outer ring 101, and a filter screen 107 is arranged on the inner side of the first mounting ring 103 and the second mounting ring 104. A second pipe 2 is arranged at the bottom end of the first pipe 1, and a lower flange 6 is installed between the first pipe 1 and the second pipe 2. An upper flange 5 is arranged on one side of the lower flange 6, and a sealing ring 8 is installed between the upper flange 5 and the lower flange 6. The upper flange 5 and the lower flange 6 are installed by a first bolt 7 penetrating the outer surface, and a first pressure sensor 9 is installed at one end of the axial surface of the lower flange 6.
[0026] Furthermore, the venturi tube 15 includes a polyurethane coating 151, a polyimide coating 152 and polyvinyl chloride 153. The outside of the venturi tube 15 is provided with the polyurethane coating 151. The polyurethane coating 151 has good wear resistance and corrosion resistance, can protect the venturi tube 15 from the influence of the external environment, and prolong its service life. The inner side of the polyurethane coating 151 is provided with a polyimide coating 152. The polyimide coating 152 has excellent high temperature resistance and chemical corrosion resistance, can prevent impurities and chemicals in the water flow from corroding and damaging the inner wall of the venturi tube 15. The inner side of the venturi tube 15 is provided with polyvinyl chloride 153. The polyvinyl chloride 153 has good water resistance and pressure resistance, can ensure the stability and reliability of the venturi tube under water flow impact and pressure changes. This composite structure design can effectively improve the durability and corrosion resistance of the venturi tube 15, ensure that it can work stably and reliably in harsh environments, thereby improving the measurement accuracy and service life of the equipment.
[0027] Working principle and implementation method: A filter assembly 10 is installed at the front end of the first pipe 1 and fixed by a second bolt 11. A rotating shaft 12 and a handle 13 are provided on the outer ring 101. A rotatable limit block 102 can be quickly disassembled. A second pressure sensor 14 and a first pressure sensor 9 are placed inside the venturi tube 15. When blockage occurs, the sensor can monitor the change and notify the user of maintenance through a mobile phone or other smart device via a wireless network component 4. A pressure difference is generated when water flows through the venturi tube 15 to reflect the change in flow rate. Then the water meter body 3 calculates the speed and detects whether there is a blockage in combination with the geometric shape.
[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
