[0002] There are many different types of water meters, and ultrasonic water meters are one of them. Ultrasonic water meters are a new type of water meter that analyzes and calculates the water flow by detecting the time difference generated by the change in the speed of an ultrasonic beam when it propagates downstream and upstream in water. Ultrasonic water meters have many characteristics, generally including low starting flow rate, wide measurement range ratio, and high measurement accuracy. There are no moving parts and flow resistance elements inside it, so it will not be affected by impurities in the water, thus ensuring its working stability and long service life.

The meter body includes an inlet water channel, a first channel, a measurement channel, a second channel, and an outlet water channel that are connected in sequence to form a "convex" shape. The first ultrasonic transducer and the second ultrasonic transducer are respectively arranged on the meter body at both ends of the measurement channel. The measurement channel is composed of a first measurement pipeline and a second measurement pipeline. The flow rate of the first measurement pipeline is less than that of the second measurement pipeline and is located below the second measurement pipeline. A first electric control valve is arranged in the first measurement pipeline, and a second electric control valve is arranged in the second measurement pipeline. The first ultrasonic transducer, the second ultrasonic transducer, the first electric control valve, and the second electric control valve are all electrically connected to the controller. When applying this water meter, regardless of whether the water flow rate is large or small, the measurement accuracy is relatively high. Although this ultrasonic water meter has a good water flow monitoring function, there are still some defects in actual use. For example, when there is a small amount of leakage at the connection between the external water pipe and the water meter, it will cause inaccurate measurement of the water meter, and when the water pressure in the pipe body decreases, this problem cannot be quickly solved, the functionality of the water meter is poor, and the actual application effect is not good.

[0026] 1. In the present invention, a combined square tube is provided in a matching manner, and a water pressure regulating component is installed on the combined square tube. When the water meter is used normally, the water meter can normally record the water flow rate and water flow rate.

At this time, the water pressure sensor in the straight-through main pipe can detect it. At this time, the built-in motor can be controlled to start. The built-in motor can drive the rotating water baffle to rotate so that it is in a vertical position. At this time, the water flow can be blocked on one side of the side connecting pipe. As the water volume increases, the water pressure will gradually increase. Until the water pressure increases to the normal water pressure, the built-in motor can drive the rotating water baffle to rotate, so that the rotating water baffle deflects a certain angle, so that the water flow continues to conduct. The rotating water baffle can be adjusted to any angle according to needs, so that the water pressure of the water flow entering the straight-through main pipe approaches normal.

On one outer wall of the combined square pipe 6, a water pressure adjustment component 9 is provided, and the water pressure adjustment component 9 is used for the stable adjustment of the water pressure inside the straight-through main pipe 2.

[0041] The water collection component 7 includes a water collection box 76 which is fixedly installed on the top surface of the combined square pipe 6. A water guide pipe 74 is fixedly installed on one outer wall of the water collection box 76. An inlet 8 is provided on the top surface of the combined square pipe 6. One end of the water guide pipe 74 is fixedly connected to the inlet 8. A control valve 75 is fixedly installed outside the water guide pipe 74. An internal water liquid filter block 71 and a bottom screen 73 are arranged inside the water collection box 76. The heights of the internal water liquid filter block 71 and the bottom screen 73 are higher than the height of the water guide pipe 74. The internal water liquid filter block 71 is composed of a filter layer, an activated carbon adsorption layer, an odor removal layer and a particle adsorption layer, and the filter layer, the activated carbon adsorption layer, the odor removal layer and the particle adsorption layer are arranged step by step from top to bottom.

[0042] The specific implementation method is as follows: When the water meter is installed outdoors and is in normal use, some water liquids in the external environment can be collected by the water collection component 7. The internal water liquid filter block 71 in the water collection component 7 can effectively filter and purify the water liquid and continuously store it in the internal water liquid filter block 71. When there is a leakage at the connection between the water meter and the external connecting pipe, the humidity sensor arranged at the connection between the straight main pipe 2 and the side connecting pipe 5 can detect it. At this time, the control valve 75 can be automatically controlled to open, and part of the collected water liquid is introduced into the combined square pipe 6, so as to fill the error caused by the water body leakage, thereby further improving the accuracy of the application of the water meter.

[0043] The water pressure regulating component 9 includes an internal motor 91 which is fixedly installed on one outer wall of the combined square pipe 6. A waterproof housing 92 is fixedly installed outside the internal motor 91. One end of the output shaft of the internal motor 91 is fixedly installed with a rotating shaft, and one end of the rotating shaft is fixedly installed with a rotating water baffle 94. The rotating water baffle 94 is located inside the combined square pipe 6. Installation side holes 93 are arranged on both outer walls of the rotating water baffle 94. Installation shafts 96 are rotatably installed inside the installation side holes 93. Obliquely arranged flow disturbing vanes 95 are fixedly installed outside the installation shafts 96.

[0044] The specific implementation method is as follows: When the water meter is in normal use, it can normally record the water flow rate and water flow velocity. When the water pressure in the main water supply pipe is insufficient or other situations occur, the water pressure flowing into the straight-through main pipe 2 will also decrease. At this time, the water pressure sensor in the straight-through main pipe 2 can detect it. At this time, the built-in motor 91 can be controlled to start. The built-in motor 91 can drive the rotary water baffle 94 to rotate and make it in the vertical position. At this time, the water flow can be blocked on one side of the side connection pipe 5. As the water volume increases, the water pressure will gradually increase. Until when the water pressure increases to the normal water pressure, the built-in motor 91 can drive the rotary water baffle 94 to rotate, so that the rotary water baffle 94 deflects a certain angle, allowing the water flow to continue to conduct. According to requirements, the rotary water baffle 94 can be adjusted to any angle, making the water flow pressure entering the straight-through main pipe 2 approach the normal level, ensuring normal water use by users. And the rotary water baffle 94 is provided with self-driven inclined spoiler vanes 95. When the water flow is flowing, it can generate an impact force on the inclined spoiler vanes 95, thereby controlling the rotation of the inclined spoiler vanes 95. The rotation can play a certain disturbing role on the water flow, thereby increasing the water flow rate and preventing impurities in the water body from depositing on the inner wall of the water pipe and the connection of the water pipes.

[0045] Through this design, this water meter can not only accurately monitor the flow rate and flow volume of the water body, but also intelligently regulate the water pressure when the water pressure of the water body is insufficient, ensuring the water use requirements of users, greatly improving the functionality of this water meter. At the same time, when the water body is flowing, it can perform self-driven spoiler treatment on the water body, thereby increasing the water flow rate and preventing the deposition of water body impurities, resulting in blockage in the water pipe, greatly improving the functionality and actual application effect of this water meter.

[0046] A bottom groove is provided on the bottom surface of the installation base 3, and a side clamping block groove 10 is provided on the side surface of the installation base 3. A quick assembly component 4 is provided inside the bottom groove. The quick assembly component 4 is used for the quick installation of this ultrasonic water meter. The quick assembly component 4 includes an installation inner plate 44 and a limit sliding shaft 47. The limit sliding shaft 47 is longitudinally fixedly installed inside the bottom groove. A sleeve spring 46 is sleeved outside the limit sliding shaft 47. A pressure-bearing moving bar 45 is slidably installed outside the limit sliding shaft 47. The bottom end of the pressure-bearing moving bar 45 is located outside the installation base 3. The pressure-bearing moving bar 45 is located below the sleeve spring 46. Clamping side rods 41 are fixedly installed on both outer walls of the pressure-bearing moving bar 45. The installation inner plate 44 is fixedly installed inside the side clamping block groove 10. A side push spring 42 is fixedly installed on one outer wall of the installation inner plate 44. One end of the side push spring 42 is fixedly installed with an installation side clamping block 43. A clamping hole 48 is provided on the top surface of the installation side clamping block 43. The bottom end of the clamping side rod 41 is clamped into the clamping hole 48. The installation side clamping block 43 is slidably connected with the side clamping block groove 10.

[0047] The specific implementation method is as follows: when the water meter needs to be assembled, the water meter is directly installed vertically in the installation area. At this time, the pressure-bearing movable bar 45 can contact the installation area. At this time, the pressure-bearing movable bar 45 is squeezed and moved upward. At this time, the locking side rod 41 moves upward synchronously. When the bottom end of the locking side rod 41 disengages from the top surface clamping hole of the installation side clamping block 43, the side thrust spring 42 loses its limiting effect. The side thrust spring 42 can control the side spring of the installation side clamping block 43. The side-springing installation side clamping block 43 can automatically be clamped into the side clamping hole of the installation area, so that the rapid positioning and installation of the water meter can be quickly completed without the use of any special installation tools and a large number of assembly parts, which greatly improves the installation and positioning efficiency and convenience of the water meter and improves the actual application effect of the water meter.

[0048] Working principle: when the water meter needs to be assembled, the water meter is directly installed vertically in the installation area. At this time, the pressure-bearing movable bar 45 can contact the installation area. At this time, the pressure-bearing movable bar 45 is squeezed and moved upward. At this time, the locking side rod 41 moves upward synchronously. When the bottom end of the locking side rod 41 is separated from the top surface clamping hole of the installation side clamping block 43, the side push spring 42 loses its limiting effect. The side push spring 42 can control the installation side clamping block 43 to bounce sideways. The side-bounced installation side clamping block 43 can automatically snap into the side clamping hole of the installation area, so that the rapid positioning installation of the water meter can be quickly completed without the need for any special installation tools and a large amount of assembly The parts greatly improve the installation and positioning efficiency and convenience of the water meter, and improve the actual application effect of the water meter; when the water meter is installed outdoors, when the water meter is used normally, some water in the external environment can be collected by the water collection component 7, and the built-in water filter block 71 in the water collection component 7 can effectively filter and purify the water, and continuously store it in the built-in water filter block 71. When the water meter and the external connection pipe leak, the humidity sensor set at the connection between the straight main pipe 2 and the side connecting pipe 5 can detect it. At this time, the control valve 75 can be automatically controlled to open, and a part of the collected water is introduced into the combined square pipe 6. Thereby filling the error caused by water leakage, the accuracy of the water meter application can be further improved. When the water meter is in normal use, the water meter can normally record the water flow rate and water flow rate. When the water pressure in the main water supply pipe is insufficient, the water pressure flowing into the straight pipe 2 will also decrease. At this time, the water pressure sensor in the straight pipe 2 can detect it. At this time, the built-in motor 91 can be controlled to start. The built-in motor 91 can drive the rotating water baffle 94 to rotate so that it is in a vertical position. At this time, the water flow can be blocked on one side of the side connecting pipe 5. As the water volume increases, the water pressure will gradually increase until the water pressure increases to the normal water pressure. The built-in motor 91 can drive the rotating water baffle plate 94 to rotate, so that the rotating water baffle plate 94 is deflected at a certain angle, so that the water flow continues to be conducted. The rotating water baffle plate 94 can be adjusted to any angle according to needs, so that the water pressure of the water flow entering the straight-through main pipe 2 is close to a normal level, ensuring normal water use for users. The rotating water baffle plate 94 is provided with a self-driven inclined spoiler blade 95. When the water flows, it can generate an impact force on the inclined spoiler blade 95, thereby controlling the inclined spoiler blade 95 to rotate. The rotation can have a certain disturbing effect on the water flow, thereby increasing the water flow rate and preventing impurities in the water from being deposited on the inner wall of the water pipe and the connection between the water pipe.
