[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figures 1 to 6 As shown, an ultrasonic water meter according to an embodiment of the present invention comprises a water meter body 1; an output port 11 is fixedly connected to one end of the water meter body 1, and an input box 12 is fixedly connected to the other end of the water meter body 1; a double-port channel 13 is provided inside the input box 12, and the double-port channel 13 can be connected to the output port 11 through the water meter body 1; a filter screen 14 is fixedly connected inside the input box 12; a diverter plate 15 is rotatably connected to the inside of the input box 12 near the filter screen 14, and a diverter plate 15 is provided on the diverter plate 15 There is a crescent groove; the input box 12 is fixedly connected to a No. 1 fixing frame 16 on the outer wall away from the water meter body 1; the bottom end of the No. 1 fixing frame 16 is fixedly connected to a servo motor 17, and the output end of the servo motor 17 is fixedly connected to the central outer wall of the diverter plate 15; the ultrasonic water meter is composed of a water meter body 1, an output port 11 and an input box 12 to form a main frame, a double-port channel 13 is opened inside the input box 12 and has two water inlets and one water outlet, and the double-port channel 13 and the water meter body 1 and the output port 11 form a channel for water flow measurement,

[0030] During operation, two water sources enter from the two water inlets of the double-port channel 13 respectively. At this time, the diverter plate 15 blocks one water inlet of the double-port channel 13, while the other water inlet of the double-port channel 13 is opened. After the water enters the interior of the input box 12, it reaches the crescent groove. The filter plate 14 filters the water and filters out the impurities carried in the water. The filtered water passes through the double-port channel 13 and reaches the water meter body 1 for ultrasonic detection. The detected water is discharged from the output port 11, which reduces the attenuation and interference of the ultrasonic signal caused by bubbles generated by impurities, thereby improving the accuracy and reliability of ultrasonic water meter measurement.

[0031] At the same time, when the water inlet of the dual-port channel 13 is blocked by impurities filtered by the filter screen 14, the output end of the servo motor 17 on the No. 1 fixed frame 16 rotates, and the output end of the servo motor 17 drives the diverter plate 15 to rotate, so that the crescent groove of the diverter plate 15 rotates to the other water inlet, and the other water inlet is opened for uninterrupted metering of water flow, and the inner wall of the diverter plate 15 blocks the blocked water inlet in an offset manner. It should be noted that the two water inlets of the dual-port channel 13 are switched for use, and the output end of the servo motor 17 needs to drive the diverter plate 15 to switch and rotate in both directions, so as to switch the two water inlets of the dual-port channel 13 and reduce the occurrence of empty pipes in the ultrasonic water meter.

[0032] like Figure 1 , Figure 2 Figure 4 and Figure 6 As shown, the two ends of the crescent groove of the diverter plate 15 are fixedly connected with scrapers 2 respectively; the diverter plate 15 is provided with a No. 1 discharge port 21 near the two scrapers 2 respectively; the central bottom end of the input box 12 is provided with a No. 2 discharge port 22, and the No. 2 discharge port 22 can be connected with the No. 1 discharge port 21;

[0033] When a large amount of impurities are filtered on the filter screen 14 and one of the water inlets of the double-port channel 13 is blocked, the output end of the servo motor 17 is used to drive the diverter plate 15 to rotate forward, and the scraper 2 close to the blocked water inlet scrapes the blocked part of the filter screen 14, and the impurities are scraped and dropped into the crescent groove by the scraper 2. As the diverter plate 15 continues to rotate forward, when the No. 1 discharge port 21 corresponds to the No. 2 discharge port 22, the impurities scraped off by the water entering the crescent groove are discharged from the No. 1 discharge port 21 and the No. 2 discharge port 22;

[0034] When the other water inlet of the double-port channel 13 is blocked, the output end of the servo motor 17 drives the diverter plate 15 to rotate in the opposite direction, and the scraper 2 close to the other blocked water inlet scrapes the blocked part of the filter screen plate 14, and the impurities are scraped and dropped into the crescent groove by the scraper 2. As the diverter plate 15 continues to rotate in the opposite direction, when the other No. 1 discharge port 21 corresponds to the No. 2 discharge port 22, the water entering the crescent groove flushes the scraped impurities and discharges them from the other No. 1 discharge port 21 and the No. 2 discharge port 22, thereby cleaning and discharging the impurities filtered by the filter screen plate 14.

[0035] like Figures 1 to 4 , Figure 6As shown, a partition plate 3 is fixedly connected to the inner wall of the diverter plate 15 near the No. 1 feed opening 21, and the No. 1 feed opening 21 is located between the scraper 2 and the partition plate 3; a plurality of through holes are opened on the partition plate 3, and the diameter of the end of the plurality of through holes near the No. 1 feed opening 21 is large, and the diameter of the end away from the No. 1 feed opening 21 is small; an arc block 31 is fixedly connected to one side of the outer wall of the partition plate 3 near the No. 1 feed opening 21;

[0036] When the scraper 2 scrapes off the impurities attached to the filter screen plate 14, the impurities fall into the crescent groove and are collected, and the impurities are collected between the partition plate 3 and the scraper 2. As the diverter plate 15 rotates, the No. 1 discharge port 21 rotates close to the No. 2 discharge port 22. The impurities sink due to their mass, and the arc block 31 guides and collects the impurities, so that the scraped impurities sink in the No. 1 discharge port 21 for temporary storage until the No. 1 discharge port 21 and the No. 2 discharge port 22 correspond to each other, and the scraped impurities mixed with water are discharged from the No. 2 discharge port 22, which plays a role in narrowing the range of impurities storage and cleaning;

[0037] At the same time, large particles of impurities will be collected between the partition plate 3 and the scraper 2, while some fine impurities will rush into the multiple through holes of the partition plate 3. Relying on the characteristics of the multiple through holes that have a large diameter at one end and a small diameter at the other end, some fine impurities will accumulate between the two partition plates 3 after passing through the multiple through holes. Since the diameter between the two partition plates 3 is small, it is easy for impurities to enter but not easy to exit between the two partition plates 3, thereby accumulating some fine impurities.

[0038] An adsorption plate 4 is fixedly connected to the inner wall of the diverter plate 15 and located between the two partition plates 3; a plurality of activated carbon particles are fixedly connected to the adsorption plate 4;

[0039] When some fine impurities are accumulated between the two partition plates 3, the adsorption plate 4 is fixed to the inner wall of the bottom end of the diverter plate 15, and a plurality of activated carbon particles are used to adsorb the impurities entering between the two partition plates 3, thereby reducing the situation where the impurities entering between the two partition plates 3 rush out of the storage range and improving the collection effect of fine impurities.

[0040] like Figures 1 to 5 As shown, the outer wall of the input box 12 is respectively fixed with a limit frame 5 near the two water inlets of the double-port channel 13, and the cross-sectional shape of the limit frame 5 is a horseshoe shape; the two limit frames 5 are plugged with a matching tube 51, and the matching tube 51 is located between the limit frame 5 and the input box 12;

[0041] Two matching pipes 51 are respectively installed at the two water inlets of the double-port channel 13 on the ultrasonic water meter. The two matching pipes 51 are respectively inserted into the two limit frames 5 on the outer wall of the input box 12 from top to bottom, so that the two matching pipes 51 correspond to the two water inlets of the double-port channel 13 respectively. The two matching pipes 51 are used to transport two water sources into the internal measurement of the water meter body 1.

[0042] When maintenance is required, hold the outer walls of the two matching tubes 51 in turn and lift the matching tubes 51 from the horseshoe-shaped limit frame 5 from bottom to top, so that the two matching tubes 51 can be removed from the input box 12. After the maintenance of the ultrasonic water meter is completed, insert the two matching tubes 51 into the two limit frames 5 on the outer wall of the input box 12 from top to bottom, so that the two matching tubes 51 correspond to the two water inlets of the double-port channel 13, thereby playing the role of quick disassembly and maintenance of the ultrasonic water meter.

[0043] The input box 12 is slidably connected to a sliding frame 6, and one end of the sliding frame 6 close to the diverter plate 15 and penetrating the filter screen plate 14 is in a trapezoidal shape; a first elastic member 61 is fixedly connected between the inner wall of the input box 12 and the sliding frame 6; a limit plate 62 is provided on the two matching tubes 51; a connecting component is provided on the end of the sliding frame 6 away from the filter screen plate 14, and the connecting component is used to connect the sliding frame 6 and the two limit plates 62;

[0044] When the two matching tubes 51 are respectively inserted into the two limiting frames 5, the trapezoidal end of the sliding frame 6 protrudes from the filter screen plate 14 and is located in the crescent groove of the diverter plate 15. The two limiting plates 62 connected to the sliding frame 6 by the connecting assembly are now away from the two matching tubes 51. The diverter plate 15 is driven to rotate by the output end of the servo motor 17, and the inner wall of the diverter plate 15 squeezes the trapezoidal end of the sliding frame 6 protruding from the filter screen plate 14. The trapezoidal end of the sliding frame 6 is squeezed and pressed into the filter screen plate 14 by the diverter plate 15. 4, the first elastic member 61 is subjected to the force of sliding, squeezing and contraction by the sliding frame 6, and the two limit plates 62 installed by the connecting assembly slide at the same time to limit the top ends of the two matching tubes 51 respectively, playing the role of fixing and limiting the two matching tubes 51. At the same time, when the limit of the two matching tubes 51 is cancelled, the output end of the servo motor 17 drives the diverter plate 15 to rotate, so that one end of the trapezoid of the sliding frame 6 slides into the crescent groove, and the elastic reset of the first elastic member 61 can push the two limit plates 62 away from the two matching tubes 51.

[0045] The connecting assembly includes a support plate 7, a rotating shaft 71 and a connecting plate 72; the support plate 7 is fixedly connected to the outer wall of one end of the sliding frame 6 away from the filter screen plate 14; the two rotating shafts 71 are rotatably connected to the two ends of the support plate 7 respectively; the connecting plate 72 is fixedly connected to the rotating shaft 71, and the end of the connecting plate 72 away from the rotating shaft 71 is fixedly connected to the outer wall of the limiting plate 62; and a limiting hole is provided on the side of the connecting plate 72 close to the input box 12; the outer wall of the input box 12 is fixedly connected to two limiting rods 73, and the limiting rods 73 correspond to the limiting holes;

[0046] When the two limiting plates 62 are connected, the support plate 7 is fixed to the end of the sliding frame 6 away from the filter screen plate 14, and the two ends of the support plate 7 are connected to the limiting plate 62 by the rotating shaft 71 and the connecting plate 72 respectively. When the matching tube 51 is limited, the connecting plate 72 rotates to be vertical. As the sliding frame 6 and the first elastic member 61 are squeezed by the diverter plate 15, the connecting plate 72 connected by the rotating shaft 71 on the support plate 7 slides and fits the outer wall of the input box 12, and the limiting plug rod 73 is correspondingly inserted into the limiting hole of the connecting plate 72, so that the limiting plate 62 is limited on the matching tube 51 and fixed to it, so as to limit the matching tube 51;

[0047] When the matching tube 51 is disassembled, the limit plate 62 is reset and pushed away from the matching tube 51 by the elastic force of the No. 1 elastic member 61, and the limit rod 73 leaves the limit hole of the connecting plate 72. The connecting plate 72 is held by hand and rotated with the rotating shaft 71 to rotate the connecting plate 72 to the horizontal direction. At this time, the matching tube 51 can be taken out from the limit frame 5, thereby achieving the purpose of disassembling the matching tube 51.

[0048] like Figures 1 to 5 As shown, the top of the input box 12 is fixedly connected to a power supply box 8, and a plurality of power supply slots are provided in the power supply box 8; a second fixing frame 81 is fixedly connected to one end of the sliding frame 6 away from the filter screen plate 14; a blocking plate 82 is fixedly connected to one end of the second fixing frame 81 away from the sliding frame 6, and the blocking plate 82 is slidably connected to the power supply box 8;

[0049] When the ultrasonic water meter is in use, multiple functions of the ultrasonic water meter need to rely on electric drive. Multiple batteries are respectively inserted into multiple power supply slots in the power supply box 8 to power the ultrasonic water meter. Common faults of ultrasonic water meters are battery exhaustion and excessive bubble generation. When repairing the ultrasonic water meter, it is inevitable to check the battery placement and battery exhaustion. The No. 2 fixing frame 81 is fixed to the end of the sliding frame 6 away from the filter plate 14 to support the blocking plate 82. The blocking plate 82 is synchronously blocked with the limit plate 62 stuck in the upper limit of the matching tube 51 to block the top of the power supply box 8, and the multiple batteries are blocked in the power supply box 8 for use. At the same time, the blocking plate 82 is synchronously slid open the top of the power supply box 8 with the limit plate 62 away from the matching tube 51, so that the multiple batteries are exposed for easy inspection, thereby playing a role in checking the batteries installed in the power supply box 8.

[0050] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a plurality of the power supply slots are slidably connected with ejector plates 9; a No. 2 elastic member is fixedly connected between the ejector plate 9 and the inner wall of the power supply slot; when the ultrasonic water meter is repaired, after the blocking plate 82 slides with the No. 2 fixing frame 81 to open the top of the power supply box 8, the No. 2 elastic member that was originally squeezed and contracted is elastically reset, and the No. 2 elastic member pushes up the ejector plate 9, so that the ejector plate 9 pushes up the battery installed in the power supply box 8 by one-fifth of the height. The approximate height can be seen by referring to the limit frame 5 in the attached figure, which plays a role in ejecting the battery for easy picking;

[0051] At the same time, after the inspection is completed, the multiple batteries are placed on the ejection plate 9. When the blocking plate 82 is reset, it can squeeze the outer walls of the multiple batteries and press the multiple batteries into the power supply box 8 to limit the power supply.

[0052] A placement groove 91 is formed at the top of the blocking plate 82; the cross-sectional shape of the placement groove 91 is a semicircular arc;

[0053] When multiple batteries are ejected for maintenance, workers can remove the ejected batteries and place them in semicircular placement grooves 91 respectively, and check the battery usage in turn. After checking the status of each battery, the usable battery is put back into the power supply box 8 and the unusable battery is replaced, thereby playing the role of placing and repairing multiple batteries.

[0054] Working process: two water sources enter from the two water inlets of the double-port channel 13 respectively. At this time, the diverter plate 15 blocks one water inlet of the double-port channel 13, and the other water inlet of the double-port channel 13 is opened. After the water enters the interior of the input box 12, it reaches the crescent groove. The filter plate 14 filters the water and filters out the impurities carried in the water. The filtered water passes through the double-port channel 13 and reaches the water meter body 1 for ultrasonic detection. The detected water is discharged from the output port 11, which reduces the attenuation and interference of the ultrasonic signal caused by bubbles generated by impurities, and improves the accuracy and reliability of ultrasonic water meter measurement. At the same time, when the water inlet of the double-port channel 13 being used is blocked by impurities filtered by the filter plate 14, the fixed No. The output end of the servo motor 17 on the frame 16 rotates, and the output end of the servo motor 17 drives the diverter plate 15 to rotate, so that the crescent groove of the diverter plate 15 rotates to the other water inlet, opens the other water inlet for uninterrupted metering of water flow, and the inner wall of the diverter plate 15 blocks the blocked water inlet in a staggered manner. It should be noted that the two water inlets of the double-port channel 13 are switched for use, and the output end of the servo motor 17 is required to drive the diverter plate 15 to switch and rotate in both directions in both directions, so as to switch the two water inlets of the double-port channel 13 for use; when a large amount of impurities are filtered on the filter plate 14 to block one water inlet of the double-port channel 13, the output end of the servo motor 17 is used to drive the diverter plate 15 to rotate forward, and the scraper near the blocked water inlet is driven to rotate forward. The blade 2 then scrapes the blocked part of the filter screen plate 14, and the impurities are scraped and dropped into the crescent groove by the scraper 2. As the diverter plate 15 continues to rotate forward, when the No. 1 discharge port 21 corresponds to the No. 2 discharge port 22, the water entering the crescent groove flushes the scraped impurities and discharges them from the No. 1 discharge port 21 and the No. 2 discharge port 22; when the other water inlet of the double-port channel 13 is blocked, the output end of the servo motor 17 drives the diverter plate 15 to rotate in the opposite direction, and the scraper 2 close to the other blocked water inlet then scrapes the blocked part of the filter screen plate 14, and the impurities are scraped and dropped into the crescent groove by the scraper 2. As the diverter plate 15 continues to rotate in the opposite direction, when the other No. 1 discharge port 21 corresponds to the No. 2 discharge port 22, the impurities enter the crescent groove. The impurities scraped off by the water in the filter are discharged from another No. 1 discharge port 21 and No. 2 discharge port 22, which plays a role in cleaning and discharging the impurities filtered by the filter screen plate 14; when the scraper 2 scrapes off the impurities attached to the filter screen plate 14, the impurities fall into the crescent groove for collection, and the impurities are collected between the partition plate 3 and the scraper 2. As the diverter plate 15 rotates, the No. 1 discharge port 21 rotates close to the No. 2 discharge port 22, and the impurities sink due to mass. The arc block 31 guides the collection of impurities, so that the scraped impurities sink in the No. 1 discharge port 21 for temporary storage until the No. 1 discharge port 21 and the No. 2 discharge port 22 correspond to each other, and the scraped impurities mixed with water are discharged from the No. 2 discharge port 22, which plays a role in narrowing the range of impurities storage and cleaning;At the same time, large particles of impurities will be collected between the partition plate 3 and the scraper 2, while some fine impurities will rush into the multiple through holes of the partition plate 3. Relying on the characteristics of the multiple through holes that one end has a large diameter and the other end has a small diameter, some fine impurities are accumulated between the two partition plates 3 after passing through the multiple through holes. Since the diameter between the two partition plates 3 is small, it is easy for impurities to enter but not easy to exit between the two partition plates 3, which plays a role in accumulating some fine impurities. When some fine impurities are accumulated between the two partition plates 3, the adsorption plate 4 is fixed to the inner wall of the bottom end of the diverter plate 15, and multiple activated carbon particles are used to adsorb the impurities entering between the two partition plates 3, thereby reducing the situation where the impurities entering between the two partition plates 3 rush out of the storage range, and improving the collection effect of fine impurities.

[0055] Two matching tubes 51 are respectively installed at the two water inlets of the double-port channel 13 on the ultrasonic water meter. The two matching tubes 51 are respectively inserted into the two limiting frames 5 on the outer wall of the input box 12 from top to bottom, so that the two matching tubes 51 correspond to the two water inlets of the double-port channel 13 respectively. The two matching tubes 51 are used to transport two water sources into the internal measurement of the water meter body 1; when maintenance is required, the outer walls of the two matching tubes 51 are held in turn, and the matching tubes 51 are lifted from the horseshoe-shaped limiting frame 5 from bottom to top, so that the two matching tubes 51 can be removed from the input box 12. After the maintenance of the ultrasonic water meter is completed, the two matching tubes 51 are respectively inserted into the two limiting frames 5 on the outer wall of the input box 12 from top to bottom, so that The two matching tubes 51 correspond to the two water inlets of the double-port channel 13, which plays a role in the quick disassembly and maintenance of the ultrasonic water meter; when the two matching tubes 51 are respectively inserted into the two limiting frames 5, the trapezoidal end of the sliding frame 6 protrudes from the filter screen plate 14 and is located in the crescent groove of the diverter plate 15. The two limiting plates 62 connected to the sliding frame 6 by the connecting assembly are now away from the two matching tubes 51, and the diverter plate 15 is driven to rotate by the output end of the servo motor 17. The inner wall of the diverter plate 15 squeezes the trapezoidal end of the sliding frame 6 protruding from the filter screen plate 14, and the trapezoidal end of the sliding frame 6 is squeezed and compressed into the inner wall of the filter screen plate 14 by the diverter plate 15, and the No. 1 elastic member 61 is squeezed and contracted by the sliding of the sliding frame 6. The two limiting plates 62 installed by the connecting assembly slide at the same time to limit the top ends of the two matching tubes 51 respectively, so as to play the role of fixing and limiting the two matching tubes 51. At the same time, when the limiting of the two matching tubes 51 is cancelled, the output end of the servo motor 17 drives the diverter plate 15 to rotate, so that one end of the trapezoid of the sliding frame 6 slides into the crescent groove, and the elastic reset of the No. 1 elastic member 61 can push the two limiting plates 62 away from the two matching tubes 51; when the two limiting plates 62 are connected, the support plate 7 is fixed to the end of the sliding frame 6 away from the filter screen plate 14, and the two ends of the support plate 7 are respectively connected to the limiting plates 62 by the rotating shaft 71 and the connecting plate 72.

[0056] When the ultrasonic water meter is in use, multiple functions of the ultrasonic water meter need to rely on electric drive. Multiple batteries are respectively inserted into multiple power supply slots in the power supply box 8 to power the ultrasonic water meter. Common faults of ultrasonic water meters are battery exhaustion and excessive bubble generation. When repairing the ultrasonic water meter, it is inevitable to check the battery placement and battery exhaustion. The second fixing frame 81 is fixed to the end of the sliding frame 6 away from the filter plate 14 to support the blocking plate 82. The blocking plate 82 is synchronously blocked with the limit plate 62 stuck in the upper limit of the matching tube 51 to block the top of the power supply box 8, and multiple batteries are blocked in the power supply box 8 for use. At the same time, the blocking plate 82 is synchronously slid open the top of the power supply box 8 with the limit plate 62 away from the matching tube 51, so that the multiple batteries are exposed for easy inspection, which plays the role of checking the batteries installed in the power supply box 8; when repairing the ultrasonic water meter, the blocking plate 82 After the No. 2 fixing frame 81 slides open the top of the power supply box 8, the elastic force of the No. 2 elastic member that was originally squeezed and contracted is restored, and the No. 2 elastic member pushes up the ejection plate 9, so that the ejection plate 9 will push the battery installed in the power supply box 8 to one-fifth of the height. The approximate height can be seen by referring to the limit frame 5 in the attached figure, which plays a role in facilitating the picking up of the battery; at the same time, after the inspection is completed, multiple batteries are placed on the ejection plate 9, and the blocking plate 82 can squeeze the outer walls of the multiple batteries when it is reset, and press the multiple batteries into the power supply box 8 for limited power supply; when multiple batteries are ejected for inspection, the worker can remove the multiple batteries that have been ejected, and place them in the semicircular placement groove 91 respectively, and check the battery usage in turn. After checking the status of each battery, the battery that can still be used is put back into the power supply box 8, and the unusable battery is replaced, which plays a role in placing and inspecting multiple batteries.
