Description

Technical Field

[0001] This utility model relates to the field of water meter performance testing technology, and in particular to water meter testing equipment. Background Technology

[0002] Existing methods for testing multiple water meters typically involve connecting all the meters in series, with each meter linked end-to-end and receiving water from one end of the same pipeline and exiting from the other. In this series configuration, if one meter shuts off, all the meters will stop receiving water. This affects the testing progress and limits the number of meters that can be tested. Utility Model Content

[0003] The main purpose of this utility model is to provide a water meter testing device that ensures that when multiple water meters are tested simultaneously, they do not interfere with each other, and that stopping the water flow from any one water meter will not interfere with the testing process of other water meters.

[0004] To achieve the above objectives, this utility model proposes a water meter testing device, comprising:

[0005] A water supply assembly includes a water storage tank, a water supply pipeline, and a return pipeline. The water storage tank has a return outlet and a supply outlet spaced apart. The supply outlet is connected to the water supply pipeline, and the return outlet is connected to the return pipeline. The water supply assembly also includes a pump body connecting the water storage tank and the water supply pipeline; and...

[0006] The test assembly includes multiple test pipes, each of which is used for detachable connection to the water meter to be tested. One end of each test pipe is connected to the water supply pipe, and the other end is connected to the return water pipe. Each test pipe is equipped with a control valve that can be opened and closed.

[0007] The water in the water storage tank is transported to the test pipeline through the water supply pipeline, and then flows back to the water storage tank through the return water pipeline after passing through the water meter to be tested.

[0008] In one embodiment, the water supply pipeline includes:

[0009] The first main channel is connected to the water inlet; and

[0010] Multiple first branch paths are arranged at intervals and are all connected to the first main path. Each first branch path can be connected to at least one of the test pipelines.

[0011] In one embodiment, the return water pipeline includes:

[0012] The second main water path is connected to the return water inlet; and,

[0013] Multiple second branch paths are arranged at intervals and are all connected to the second main path. Each second branch path is connected to at least one of the test pipelines.

[0014] Each of the test pipelines is connected at both ends to a first branch and a second branch, respectively.

[0015] In one embodiment, a plurality of second branch paths and a plurality of first branch paths are arranged alternately in the vertical direction;

[0016] Each of the test pipelines is located between the second branch and the first branch, which are arranged adjacent to each other in the vertical direction.

[0017] In one embodiment, the number of second branch paths is greater than the number of first branch paths;

[0018] Multiple test pipelines form multiple test groups, and each test group includes two test pipelines arranged adjacent to each other in the vertical direction. The ends of the two test pipelines in each test group that are close to each other are connected to the same first branch path.

[0019] In one embodiment, the water flow directions of the two test pipelines in each test group are opposite.

[0020] In one embodiment, a check valve is provided on the portion of each test pipeline near the return water pipeline.

[0021] In one embodiment, the water meter testing equipment includes a mounting frame having a panel and a frame connected to the panel and disposed on the side of the panel;

[0022] At least a portion of the water delivery assembly is fixed to the frame;

[0023] The middle part of the test pipeline is exposed on the panel, and the end passes through the panel and communicates with the water supply assembly.

[0024] In one embodiment, the panel has a plurality of spaced mounting slots, and a plurality of test pipelines are provided between two adjacent mounting slots;

[0025] The mounting bracket also includes a water receiving component, one side of which is provided with a water receiving groove. The water receiving component is rotatably mounted to the panel. During rotation, the water receiving component has a storage position within the mounting groove and a water receiving position where the water receiving groove faces upwards.

[0026] In one embodiment, the water meter testing device further includes:

[0027] A gateway, electrically connected to the plurality of said control valves and used for communication connection to a data platform; and / or,

[0028] A display screen is used to electrically connect to the water meter under test to display the real-time data of the water meter under test.

[0029] In this invention, water in the storage tank is transported to the test pipeline via the water supply pipeline, then flows through the water meter under test and back to the storage tank via the return pipeline, forming a complete circulation loop to ensure water circulation during the water meter testing process. Since the supply and return pipelines are independent, multiple test pipelines can be connected in parallel, with each control valve controlling only the flow of water into a single test pipeline, thus affecting the testing process of a single water meter. This allows for simultaneous testing of multiple water meters without interference. Furthermore, based on this structure, the number of water meters tested simultaneously can be increased or decreased by rationally adjusting the shape, length, and number of the test pipelines, improving testing efficiency.

[0038] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] It should be noted that if the embodiments of this utility model involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0041] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0042] Existing water meter testing solutions typically involve three steps: connecting all water meters in series; pumping water from the inlet to the outlet, ensuring a unified flow back to the water tank; and transmitting images of the water meter displays to a microcomputer. In this series-connected approach, if the valve on one water meter is closed, all water meters will stop flowing. This affects the testing progress and limits the number of water meters that can be tested.

[0043] In view of this, the present invention provides a water meter testing device, which ensures that when multiple water meters are connected to water at the same time, closing the valve of any one water meter to stop the water flow will not affect the normal water flow of other water meters.

[0044] Please refer to Figures 1 to 4 The water meter testing equipment 100 includes a water supply component 1 and a testing component. The water supply component 1 includes a water storage tank 11, a water supply pipeline 12, and a return water pipeline 13. The water storage tank 11 has a return water port and a water supply port spaced apart. The water supply port is connected to the water supply pipeline 12, and the return water port is connected to the return water pipeline 13. The water supply component 1 also includes a pump body 14 that connects the water storage tank 11 and the water supply pipeline 12. The testing component includes multiple testing pipelines 21. Each testing pipeline 21 is used for detachable connection to the water meter to be tested. One end of each testing pipeline 21 is connected to the water supply pipeline 12, and the other end is connected to the return water pipeline 13. Each testing pipeline 21 is provided with a control valve 22 that can be opened and closed near the water supply pipeline 12. Water in the water storage tank 11 is transported to the testing pipeline 21 through the water supply pipeline 12, and then flows back to the water storage tank 11 through the return water pipeline 13 after passing through the water meter to be tested.

[0045] In this invention, the pump body 14 pumps water from the storage tank 11 to the water supply pipeline 12, ensuring the power of the entire water circulation. Water from the storage tank 11 is transported through the water supply pipeline 12 to the test pipeline 21, then through the water meter to be tested, and finally guided back to the storage tank 11 by the return pipeline 13, thus forming a complete circulation loop to ensure water circulation during the water meter testing process. Since the water supply pipeline 12 and the return pipeline 13 are independent of each other, multiple test pipelines 21 can form a parallel connection when connected. Each control valve 22 only controls the water inlet / outlet of a single test pipeline 21, thus affecting the testing process of a single water meter to be tested, thereby achieving the effect of simultaneous testing of multiple water meters without interference. Furthermore, based on this structure, the number of water meters tested simultaneously can be increased or decreased by reasonably setting the shape, length, and number of the test pipelines 21, improving testing efficiency.

[0046] The control valve 22 should at least have the function of regulating the opening and closing of the pipeline. Depending on the actual needs, the control valve 22 can be set as a solenoid valve. In this embodiment, the control valve 22 is set as a shut-off valve. A shut-off valve is a valve device that can regulate the flow rate of the pipeline and control the flow of the medium, thereby enabling it to open and close the pipeline passage and control the flow rate and pressure.

[0047] The test pipeline 21 needs to be able to connect the inlet and outlet of the water meter to be tested. It should be understood that an interface should be provided on the test pipeline 21 so that it can be detachably installed with the water meter to be tested. This interface is set as a movable threaded interface so that it can be adapted to water meters of different brands and models and has good compatibility.

[0048] The length and shape of the water supply pipe 12 and the return pipe 13 are not limited. The test pipe 21 should be reasonably set according to the spacing and arrangement of the water supply pipe 12 and the return pipe 13. For example, the test pipe 21 can be straight or curved.

[0049] It should be understood that, depending on the different structural shapes, the test pipe 21 and the water supply pipe 12 and / or the return pipe 13 can be connected by a tee fitting. When the test pipe 21 is curved, it is composed of multiple pipe segments and fittings spliced ​​together. For example, in some embodiments, the test pipe 21 is set in a U-shape, consisting of straight pipe segments and 90° elbows spliced ​​together.

[0050] The water storage tank 11 is an integrated semi-enclosed water tank. The water storage tank 11 is also equipped with a water inlet and a water outlet. The water can be drained quickly through the water outlet and replaced with a new clean water source through the water inlet.

[0051] In some embodiments, please refer to Figures 4 to 5 The water supply pipeline 12 includes a first main flow 121 and multiple first branch flows 122. The first main flow 121 is connected to the water inlet. The multiple first branch flows 122 are spaced apart and all connected to the first main flow 121. Each first branch flow 122 can be connected to at least one test pipeline 21. Specifically, the first main flow 121 can be straight, L-shaped, or have other bends to adapt to the installation space. The multiple first branch flows 122 are connected in parallel, and the extension directions of each first branch flow 122 can be the same or different. It should be noted that, depending on the pipeline layout, some locations need to be blocked.

[0052] In this embodiment, the first main flow path 121 includes three pipe segments, which extend laterally, longitudinally, and vertically, respectively. Multiple first branch flow paths 122 are all disposed on the longitudinal pipe segments.

[0053] In some embodiments, please refer to Figures 4 to 5 The return water pipe 13 includes a second main flow 131 and multiple second branch flow lines 132. The second main flow 131 is connected to the return water inlet. The multiple second branch flow lines 132 are spaced apart and all connected to the second main flow 131. Each second branch flow line 132 is connected to at least one test pipe 21. Specifically, the second main flow line 131 can be straight, L-shaped, or have other bends to adapt to the installation space. The multiple second branch flow lines 132 are arranged in parallel, and the extension directions of each second branch flow line 132 can be the same or different. It should be noted that depending on the pipe layout, some locations need to be blocked. Based on this, the two ends of the test pipe 21 are connected to the first branch flow line 122 and the second branch flow line 132, respectively.

[0054] Please refer to Figure 3 and Figure 5 Multiple second branch paths 132 and multiple first branch paths 122 are arranged alternately in the vertical direction; each test pipe 21 is located between the second branch paths 132 and the first branch paths 122 that are adjacent in the vertical direction. This arrangement makes the multiple test pipes 21 distributed vertically, and correspondingly, the water meter under test is also distributed vertically. Compared with the horizontal placement in the prior art, the overall display effect is better, and the dial of the water meter can be viewed at eye level.

[0055] In this embodiment, the number of second branch paths 132 is greater than the number of first branch paths 122; multiple test pipes 21 form multiple test groups, each test group including two test pipes 21 arranged adjacent to each other in the vertical direction, and the ends of the two test pipes 21 in each test group are connected to the same first branch path 122. That is, in the arrangement of branch paths, the uppermost and lowermost are both second branch paths 132, and the first branch path 122 is interspersed in the middle. This arrangement can reduce the number of pipes and make the arrangement more compact.

[0056] Based on the above embodiments, the water flow directions of the two test pipes 21 in each test group are opposite. For example, please refer to... Figure 3 There are five rows of pipes in total. From top to bottom, the first, third, and fifth rows are all second branch paths 132, and the second and fourth rows are all first branch paths 122. When the water flow in the first branch path 122 of the second row passes through the test group, it splits into two streams, flowing upward into the upper test pipe 21 and downward into the lower test pipe 21 respectively. After passing through the corresponding water meters to be tested, the water is returned to the water storage tank 11 by the second branch paths 122 located in the first and third rows.

[0057] It should be understood that the two control valves 22 in each test group are located on the side of the two water meters that are close to each other, and are set close to each other as a whole, each corresponding to its respective water inlet section.

[0058] Furthermore, the first main channel 121 and the second main channel 131 are located on opposite sides of multiple branch channels. This results in a compact pipeline layout that saves space.

[0059] To prevent backflow, in some embodiments, a check valve 23 is installed on the portion of each test pipe 21 near the return water pipe 13. Its main function is to ensure that the water flows in only one direction, preventing backflow and thus protecting equipment such as water pumps from damage. Accordingly, in each test group, two check valves 23 are located on the side of the two water meters furthest from each other, each corresponding to its respective outlet section.

[0060] For further details, please refer to Figures 1 to 2The water meter testing equipment 100 includes a mounting frame 3, which has a panel 31 and a frame 32 connected to the panel 31 and located to the side of the panel 31. The panel 31 is placed vertically, with the side of the panel 31 facing away from the frame 32 serving as a display surface. At least a portion of the water supply component 1 is fixed to the frame 32 for fixation. The middle part of the test pipe 21 is exposed on the panel 31, and its end passes through the panel 31 and communicates with the water supply component 1. At this time, multiple water meters to be tested are exposed on the display surface, giving the equipment a good three-dimensional visual effect. The panel 31 also serves to conceal the pipe.

[0061] Based on the above embodiments, holes need to be drilled on the panel 31 according to the dimensions of the test pipeline 21, and the hole positions must be suitable for both ordinary water meters and hot water meters. At the same time, holes are drilled on the side of the panel 31 facing the frame 32 for wire threading, so that the power supply and communication lines of the water meter are distributed inside the mounting bracket 3, improving the neatness of the equipment. The power supply and communication lines can use quick connectors, which can be easily and quickly plugged into when connecting to the monitoring and acquisition device.

[0062] Considering that even if the control valve 22 is closed, residual water in the test pipe 21 may still flow out during random replacement, in some embodiments, the panel 31 has multiple spaced mounting slots 311, with multiple test pipes 21 positioned between adjacent mounting slots 311. The mounting bracket 3 also includes a water receiving component 33, with a water receiving groove on one side. The water receiving component 33 is rotatably mounted to the mounting slot 311. During rotation, the water receiving component 33 has a retracted position within the mounting slot 311 and a water receiving position with the water receiving groove facing upwards. The size of the mounting slot 311 matches the size of the water receiving component 33. When the water receiving component 33 is in the retracted position, it can be embedded in the mounting slot 311, keeping the panel 31 flat. When the water receiving component 33 is in the water receiving position, it is in an unfolded state with the water receiving groove facing upwards, allowing it to collect residual water from the water pipes when replacing the water meter, keeping the floor dry and non-slippery.

[0063] It should be understood that, yes, a water receiving component 33 can be installed below each water meter, or a water receiving component 33 of a certain length can be installed to simultaneously receive water leakage when multiple water meters on the same straight line are disassembled.

[0064] Please refer to this again. Figure 1The water meter testing device 100 also includes a gateway 4, which is electrically connected to multiple control valves 22 and used for communication connection to a data platform. A gateway is a complex network interconnection device used to interconnect different networks above the network layer. Gateways can be used for wide area network (WAN) and local area network (LAN) connections. Their main functions are to convert protocols, data formats, and data rates. The gateway implements network interconnection at the transport layer and repackages received information to suit the needs of the destination system. This configuration allows water meter data to be uploaded to the internet platform via the water meter communication line and gateway 4, and the platform can monitor the data and control the water meter's valve operation in real time. Warning thresholds can be set for the water meter through the platform; when the water volume reaches the threshold, the inlet flow of control valve 22 will be controlled via command. Simultaneously, the water circuit short-circuit status can be detected in real time to ensure normal equipment operation. This achieves the effects of real-time monitoring of water meter data, periodic data collection for data recording, and remote control of water meter operation.

[0065] Specifically, the hardware of gateway 4 can be fixed on mounting bracket 3.

[0066] Furthermore, the water meter testing equipment 100 also includes a display screen 5, which is electrically connected to the water meter under test to display its real-time data. One or more display screens 5 can be installed on the side of the mounting bracket 3 to avoid obstructing the water meter.

[0067] In this invention, all water entering the water meters is diverted from the water supply pipeline 12, and each water meter has an independent test pipeline 21. When the valve of one water meter is closed, it does not affect the water intake of other water meters, and the other water meters can operate normally. Each water meter independently exits to the return water pipeline 13, and then the water flows back to the storage tank 11. The water output of each water meter does not affect each other. The check valve 23 ensures that the water output will not flow back to the adjacent water meter, and will not cause the water meter data to reverse. Water meter data can be collected and uploaded to the Internet platform through the water meter communication line and gateway 4, and the platform can monitor the data and control the opening and closing of the water meter valves in real time. Multiple water meters can have both top and bottom water intake, and there is a place to install the water meter regardless of whether the water intake is from the top or the bottom, which has good compatibility. Each water meter interface is a movable threaded interface, which allows the water meter to be replaced at any time, facilitating the testing of different brands and models of water meters. A water collection device 33 is installed in front of the panel 31 to collect residual water from the water pipes when the water meter is replaced, keeping the ground dry and non-slip. The storage of the water collection device 33 also helps to keep the panel 31 neat and aesthetically pleasing. The power supply and communication lines for the water meter are distributed inside the frame 32. Real-time data can be viewed through the display screen 5. This solves the problem of mutual interference in the testing of series-connected water meters in the prior art. This structure can test multiple water meters simultaneously without affecting each other. The structure of the mounting bracket 3 provides a three-dimensional visual effect after the water meters are arranged, enabling real-time monitoring of water meter data, periodic data collection to form data records, and remote control of water meter operation.

[0068] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
