DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described 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 includes 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 opened 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 to the inside of 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 opened on the diverter plate 15 There is a crescent groove; the input box 12 is fixedly connected to the outer wall of the water meter body 1 away from the first fixing bracket 16; the bottom end of the first fixing bracket 16 is fixedly connected to the 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 consists of the water meter body 1, the output port 11 and the input box 12 to form the main frame, the double-port channel 13 is opened inside the input box 12 and has two water inlets and one water outlet, the double-port channel 13 and the water meter body 1 and the output port 11 form a water flow measurement channel,

[0030] During operation, two water sources enter from the two water inlets of the dual-port channel 13 respectively. At this time, the diverter plate 15 blocks one water inlet of the dual-port channel 13, while the other water inlet of the dual-port channel 13 is opened. After the water enters the interior of the input box 12 and reaches the crescent groove, the filter plate 14 filters the water and filters out impurities carried in the water. The filtered water passes through the dual-port channel 13 and reaches the water meter body 1 for ultrasonic testing. The tested water is discharged from the output port 11, reducing 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] When the water inlet of the double-port channel 13 being used is blocked by impurities filtered by the filter screen plate 14, the servo motor 17 at the first fixed frame 16 rotates, and the output end of the servo motor 17 drives the shunt plate 15 to rotate, so that the crescent groove of the shunt 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 shunt plate 15 is misaligned to block the blocked water inlet. 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 drives the shunt plate 15 to rotate in both directions to achieve switching of the two water inlets of the double-port channel 13, thereby reducing the occurrence of empty pipes in the ultrasonic water meter.

[0032] As shown in Figure 1 , Figure 2 Figure 4 and Figure 6 , the two ends of the crescent groove of the shunt plate 15 are fixedly connected with scrapers 2; a first discharge port 21 is formed at the shunt plate 15 near the two scrapers 2; a second discharge port 22 is formed at the center bottom end of the input box 12, and the second discharge port 22 can communicate with the first discharge port 21;

[0033] When the filter screen plate 14 is blocked by a large amount of impurities, the output end of the servo motor 17 drives the shunt plate 15 to rotate forward, and the scraper 2 near the blocked water inlet scrapes the blocked part of the filter screen plate 14, and the impurities are scraped off by the scraper 2 and fall into the crescent groove. When the first discharge port 21 corresponds to the second discharge port 22, the water in the crescent groove flushes the scraped impurities out of the first discharge port 21 and the second 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 shunt plate 15 to rotate reversely, and the scraper 2 near the other blocked water inlet scrapes the blocked part of the filter screen plate 14, and the impurities are scraped off by the scraper 2 and fall into the crescent groove. When the other first discharge port 21 corresponds to the second discharge port 22, the water in the crescent groove flushes the scraped impurities out of the other first discharge port 21 and the second discharge port 22, thereby achieving the effect of cleaning and discharging the impurities filtered by the filter screen plate 14.

[0035] As shown in Figures 1 to 4 , Figure 6As shown, the inner wall of the shunt plate 15 and close to the first discharge port 21 is fixed with a partition plate 3, and the first discharge port 21 is located between the scraper 2 and the partition plate 3; a plurality of through holes are formed in the partition plate 3, the diameter of one end of the plurality of through holes close to the first discharge port 21 is large, and the diameter of the other end away from the first discharge port 21 is small; the outer wall of the partition plate 3 close to one side of the first discharge port 21 is fixed with an arc block 31;

[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 between the partition plate 3 and the scraper 2. As the shunt plate 15 rotates, the first discharge port 21 rotates close to the second discharge port 22. The impurities sink due to the mass, and the arc block 31 guides and collects the impurities. The scraped impurities are temporarily stored in the first discharge port 21, and then the scraped impurities and water are discharged from the second discharge port 22 when the first discharge port 21 corresponds to the second discharge port 22, thereby reducing the storage range of the impurities and achieving the effect of cleaning.

[0037] At the same time, large impurities are collected between the partition plate 3 and the scraper 2, and part of the small impurities are washed into the plurality of through holes of the partition plate 3. Due to the characteristics that one end of the plurality of through holes is large in diameter and the other end is small in diameter, part of the small impurities are stored between the two partition plates 3 after passing through the plurality of through holes. Because the diameter between the two partition plates 3 is small, the impurities are easy to enter but not easy to exit, thereby achieving the effect of storing part of the small impurities.

[0038] The inner wall of the shunt plate 15 and between the two partition plates 3 is fixed with an adsorption plate 4; a plurality of activated carbon particles are fixed on the adsorption plate 4;

[0039] When part of the small impurities are stored between the two partition plates 3, the adsorption plate 4 is fixed on the inner wall of the bottom end of the shunt plate 15, and the plurality of activated carbon particles adsorb the impurities entering between the two partition plates 3, thereby reducing the situation that the impurities entering between the two partition plates 3 wash out the storage range and improving the collection effect of the small impurities.

[0040] As shown in the figure, Figures 1 to 5 The outer wall of the input box 12 close to the two water inlets of the double-port channel 13 is respectively fixed with a limiting frame 5, and the cross-sectional shape of the limiting frame 5 is horseshoe-shaped; two cooperating tubes 51 are inserted into the two limiting frames 5, and the cooperating tubes 51 are located between the limiting frames 5 and the input box 12;

[0041] Two cooperating tubes 51 are respectively installed on the two water inlets of the double-port channel 13 of the ultrasonic water meter, and the two cooperating tubes 51 are respectively inserted into the two limiting frames 5 of the outer wall of the input box 12 from top to bottom, so that the two cooperating tubes 51 correspond to the two water inlets of the double-port channel 13. The two cooperating tubes 51 are used to transport two water sources into the inside of the water meter main body 1 for metering use.

[0042] When it is necessary to overhaul, the outer wall of the two matching pipes 51 is held in turn, the matching pipes 51 are lifted from the lower to the upper in the horseshoe-shaped limiting frame 5, so that the two matching pipes 51 can be detached from the input box 12, after the ultrasonic water meter is overhauled, the two matching pipes 51 are inserted into the two limiting frames 5 on the outer wall of the input box 12 from the upper to the lower respectively, so that the two matching pipes 51 correspond to the two water inlets of the double-port channel 13, and the effect of quick disassembly and overhaul of the ultrasonic water meter is achieved.

[0043] The inner wall of the input box 12 is fixedly connected with a sliding frame 6, one end of the sliding frame 6 close to the flow dividing plate 15 and penetrating through the filter screen plate 14 is arranged 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; limiting plates 62 are arranged on the two matching pipes 51; a connecting assembly is arranged on the end of the sliding frame 6 away from the filter screen plate 14, and the connecting assembly is used to connect the sliding frame 6 and the two limiting plates 62;

[0044] When the two matching pipes 51 are inserted into the two limiting frames 5 respectively, the trapezoidal end of the sliding frame 6 protrudes from the filter screen plate 14 and is located in the crescent groove of the flow dividing plate 15, the two limiting plates 62 connected by the connecting assembly are away from the two matching pipes 51 at this time, the flow dividing plate 15 is driven to rotate by the output end of the servo motor 17, the inner wall of the flow dividing plate 15 extrudes the trapezoidal end of the sliding frame 6 protruding from the filter screen plate 14, the trapezoidal end of the sliding frame 6 is extruded and compressed into the inner wall of the filter screen plate 14 by the flow dividing plate 15, the first elastic member 61 is extruded and compressed by the sliding of the sliding frame 6, the two limiting plates 62 installed by the connecting assembly are simultaneously slid to limit the top ends of the two matching pipes 51, and the effect of fixing and limiting the two matching pipes 51 is achieved, and when the limiting of the two matching pipes 51 is cancelled, the output end of the servo motor 17 drives the flow dividing plate 15 to rotate, so that the trapezoidal end of the sliding frame 6 slides into the crescent groove, and the elastic force of the first elastic member 61 can separate the two limiting plates 62 from the two matching pipes 51.

[0045] The connecting assembly comprises 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 the 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; a limiting hole is formed in the side of the connecting plate 72 close to the input box 12; two limiting insertion rods 73 are fixedly connected to the outer wall of the input box 12, and the limiting insertion 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 respectively connected to the limiting plate 62 by the rotating shaft 71 and the connecting plate 72. 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. The limiting rod 73 is correspondingly inserted into the limiting hole of the connecting plate 72, limiting the limiting plate 62 on the matching tube 51 and fixing it, thereby limiting 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 of the limit frame 5, thereby 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 bracket 81 is fixedly connected to the end of the sliding frame 6 away from the filter plate 14; a blocking plate 82 is fixedly connected to the end of the second fixing bracket 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, many functions of the ultrasonic water meter need to rely on electricity to drive. Multiple batteries are 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 bracket 81 is fixed to the end of the sliding bracket 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 being 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, exposing multiple batteries for easy inspection, thereby playing the role of 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 groove is slidingly connected with the ejection plate 9; the ejection plate 9 and the inner wall of the power supply groove is fixed with the second elastic member; when the ultrasonic water meter repair, the blocking plate 82 with the second fixed frame 81 sliding open power supply box 8 top, the original extrusion of the second elastic member spring force reset, the second elastic member will be on the ejection plate 9, so that the ejection plate 9 will be installed in the power supply box 8 of the battery on the top of the fifth height, with reference to the limiting frame 5 can be seen in the figure roughly height, play to the battery on the top of the pickup function;

[0051] At the same time after the completion of the repair, the battery is placed on the ejection plate 9, the blocking plate 82 reset can extrude the outer wall of the battery, the battery into the power supply box 8 limit power supply.

[0052] The top end of the blocking plate 82 is provided with a placing groove 91; the cross section shape of the placing groove 91 is semicircular arc shape;

[0053] When the battery is ejected for repair, the worker can take down the battery, respectively placed in the semicircular arc shape of the placing groove 91, in turn to check the use of the battery, after each battery state can continue to use the battery back to the power supply box 8, the battery can not be used, play to the battery placed in the repair function.

[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 and 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 testing. The tested water is discharged from the output port 11, reducing the attenuation and interference of the ultrasonic signal caused by bubbles generated by impurities, thereby improving the accuracy and reliability of the 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, 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. It should be noted that the two water inlets of the dual-port channel 13 are switched, and the output end of the servo motor 17 is required 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. When a large amount of impurities are filtered on the filter plate 14 and one water inlet of the dual-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 near the blocked water inlet is rotated forward. The blade 2 then scrapes the blocked part of the filter screen 14, and the impurities are scraped off by the scraper 2 and dropped into the crescent groove. 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 near the other blocked water inlet then scrapes the blocked part of the filter screen 14, and the impurities are scraped off by the scraper 2 and dropped into the crescent groove. 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 the other No. 1 discharge port 21 and the No. 2 discharge port 22, which plays the role of cleaning and discharging the impurities filtered by the filter screen 14; when the scraper 2 scrapes the impurities attached to the filter screen 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, and the impurities sink due to their 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 the role of narrowing the range of storage and cleaning of impurities;At the same time, the large particles of impurities will be collected between the partition plate 3 and the scraper 2, and part of the fine impurities will rush into the plurality of through holes of the partition plate 3, relying on the characteristics that the diameter of one end of the plurality of through holes is large and the diameter of the other end is small, so that part of the fine impurities are stored between the two partition plates 3 after passing through the plurality of through holes. Because the diameter between the two partition plates 3 is small, the impurities between the two partition plates 3 are easy to enter but not easy to exit, which plays a role in storing part of the fine impurities; when part of the fine impurities are stored between the two partition plates 3, the adsorption plate 4 is fixedly connected to the inner wall at the bottom end of the shunt plate 15, and the plurality of activated carbon particles are matched to adsorb the impurities entering between the two partition plates 3, thereby reducing the situation that the impurities entering between the two partition plates 3 rush out of the storage range, and improving the collection effect of the fine impurities;

[0056] When the ultrasonic water meter is used, the functions of the ultrasonic water meter need to be driven by electricity, and the batteries are inserted into the power supply grooves in the power supply box 8 to supply power to the ultrasonic water meter. The common faults of the ultrasonic water meter are battery depletion and excessive bubble generation. During the maintenance of the ultrasonic water meter, it is inevitable to check the battery placement and battery depletion. The second fixed frame 81 is fixed on the end of the sliding frame 6 away from the filter screen plate 14 to support the blocking plate 82. When the limiting plate 62 is clamped on the cooperating pipe 51, the blocking plate 82 synchronously blocks the top end of the power supply box 8, and the multiple batteries are blocked in the power supply box 8 for use. When the limiting plate 62 is away from the cooperating pipe 51, the blocking plate 82 synchronously slides to open the top end of the power supply box 8, and the multiple batteries are exposed for easy inspection, which plays a role in checking the batteries installed in the power supply box 8.
