Abstract
Description
Technical Field
[0001] This utility model relates to the field of water meter equipment technology, and in particular to a smart water meter data metering and compensation device. Background Technology
[0002] With the widespread application of smart water meters in water management, accurate water consumption measurement has become increasingly important. Smart water meters, with their automated data collection and remote transmission capabilities, greatly improve the efficiency and accuracy of water management, providing strong support for the rational allocation and scientific management of water resources.
[0003] However, the compensation structure currently used in some smart water meters usually relies on complex mechanical valve combinations, such as multiple throttle valves and regulating valves of different specifications connected in series or in parallel. These valves regulate water flow by opening and closing to different degrees in order to compensate for metering errors. However, this structure has problems. On the one hand, the numerous valves and complicated connecting pipelines make the overall structure bulky. The large number of parts not only increases the difficulty and cost of manufacturing, but also requires more time and effort to debug the coordination between the valves during installation. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a smart water meter data metering compensation device, thereby solving the technical problem of complex compensation structure.
[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: a smart water meter data metering compensation device, comprising: a water meter body, with a compensation part installed at one end of the water meter body; a stopper block, slidably installed within the compensation part, one end of the stopper block being tapered, the maximum diameter of the tapered end of the stopper block being adapted to the water inlet in the compensation part, the tip of the tapered end of the stopper block facing the water inlet of the compensation part, the stopper block being used to change the diameter of the water inlet in the compensation part; a drive source, installed within the compensation part, the drive source being connected to the other end of the stopper block, the drive source being used to drive the stopper block to slide, wherein the compensation part and the water meter body are tightly connected by means such as flange connection, threaded connection, etc., to ensure the sealing and stability of the connection; the stopper block is made of wear-resistant and corrosion-resistant materials, such as stainless steel, engineering plastics, etc., and the drive source can be selected such as a stepper motor, servo motor, etc., ensuring stable driving of the stopper block to slide.
[0006] In a further embodiment, a water channel is formed within the compensation section. The diameters at both ends of the water channel are adapted to the diameter of the water pipe, and the diameter in the middle is larger than the diameter of the water pipe. The inner wall of the water channel should be smooth to reduce water flow resistance. The surface roughness of the inner wall should be controlled within a certain range, such as Ra value not greater than 1.6μm. This requirement can be achieved through machining (such as boring, grinding, etc.) or surface treatment (such as polishing).
[0007] In a further embodiment, an auxiliary block is disposed in the middle of the water channel, the diameter of the auxiliary block being smaller than the diameter of the middle of the water channel, and an installation groove is provided in the auxiliary block to provide installation space for the drive source; a support frame is located between the auxiliary block and the water channel, the support frame being used to connect the auxiliary block in the water channel, wherein the dimensions of the installation groove of the auxiliary block should be precisely matched with the drive source, and the tolerances of the length, width, and depth of the installation groove should be controlled within a small range, such as ±0.1mm, to ensure that the drive source is installed stably; the structure of the support frame should have sufficient strength to withstand the impact of water flow and the weight of the auxiliary block and the drive source; the support frame can be made of metal materials (such as carbon steel, aluminum alloy, etc.), and its cross-sectional shape and dimensions should be designed according to the actual stress conditions, such as when a rectangular cross-section is used, its thickness and width should meet the strength requirements.
[0008] In a further embodiment, the threaded rod has one end stably connected to the output end of the drive source and the other end threadedly connected to the plug. The connection between the threaded rod and the output end of the drive source should be firm and reliable, and can be achieved by a key connection or a coupling. If a key connection is used, the dimensions and tolerances of the key should conform to relevant standards, and the machining accuracy of the keyway should ensure a tight fit between the key and the keyway to prevent loosening or slippage during transmission. The threaded fit between the threaded rod and the plug should be tight, and the thread pitch, thread angle, and other parameters should be accurate. The clearance should be controlled within a suitable range, such as 0.05-0.1mm, to ensure the accuracy and stability of the transmission.
[0009] In a further embodiment, a flow sensor is installed at the end of the compensation unit away from the main body of the water meter. The flow sensor is used to monitor the water flow in the water pipe. The flow sensor should have high precision and high reliability, and be able to adapt to different water quality and water flow conditions. Its measurement accuracy should meet certain standards, such as a measurement error of no more than ±1%. The protection level of the flow sensor should be selected according to the actual use environment. For example, when used in a humid environment, the protection level should not be lower than IP65. Its installation position should ensure accurate measurement of water flow and avoid external interference. During installation, it should be ensured that the sensor is perpendicular to the water flow direction and that there are no obstacles around it that affect the water flow.
[0010] In a further embodiment, a protective frame is disposed on the compensation unit; a data processing unit is installed inside the protective frame, and the data processing unit is electrically connected to the flow sensor, the drive source, and the water meter body. The protective frame should have good protective performance and be able to effectively block the intrusion of dust and moisture. The protective frame can be made of metal materials (such as stainless steel) or plastic materials (such as ABS plastic), and its sealing performance should be good, and rubber sealing gaskets can be used for sealing. The electrical connection between the data processing unit and each component should be stable and reliable. The connecting wires should have sufficient conductivity and insulation. The specifications of the wires should be selected according to the type and strength of the transmitted signal. The connection joints should adopt reliable connection methods, such as welding or crimping, to ensure the accuracy and timeliness of data transmission.
[0011] In a further embodiment, the water flow rate between the auxiliary block and the water channel per unit time is adapted to the water flow rate of the water pipe per unit time. The gap between the auxiliary block and the water channel should be reasonably designed, and the size of the gap should be determined according to factors such as the diameter of the water pipe and the water flow velocity. Generally, the gap is controlled between 2-5mm. At the same time, dead zones or vortices in the water flow should be avoided. This can be achieved by optimizing the structural shape of the auxiliary block and the water channel, such as designing the auxiliary block to be streamlined to reduce water flow resistance and turbulence.
[0012] In a further embodiment, the transition zone between the end of the water passage at the outlet of the compensation section and the middle of the water passage is conical. The conical design of the transition zone should conform to the principles of fluid mechanics, and the size of its cone angle should be reasonably selected according to factors such as water flow velocity and water passage diameter. Generally, the cone angle is controlled between 15° and 30°. Its surface should be smooth to reduce water flow resistance, and the surface roughness should be controlled to Ra value not greater than 1.6μm. This requirement can be achieved through machining or surface treatment.
[0013] Beneficial effects: Through the close cooperation of the flow sensor, data processing unit, drive source, threaded rod and plug, the structure of the compensation device is simplified; the flow sensor monitors the water flow in real time and transmits the data to the data processing unit, which analyzes the data and sends a command to the drive source, which drives the threaded rod to rotate, thereby precisely controlling the sliding of the plug to change the flow area.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in this utility model are described clearly and completely. Obviously, the described embodiments are only some, not all, of the embodiments in this utility model. All other embodiments obtained by those skilled in the art based on the embodiments in this utility model without creative effort are within the scope of protection of this utility model.
[0020] This application provides a smart water meter data metering compensation device, which solves the technical problem of complex compensation structures. In practical use, it simplifies the structure of the compensation device.
[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0022] Reference Figure 1-3 A smart water meter data measurement compensation device includes: a water meter body 1, with a compensation part 2 installed at one end of the water meter body 1; a stopper 8, slidably installed in the compensation part 2, one end of the stopper 8 being set into a cone shape, the maximum diameter of the cone end of the stopper 8 being adapted to the water inlet in the compensation part 2, the tip of the cone end of the stopper 8 facing the water inlet of the compensation part 2, the stopper 8 being used to change the diameter of the water inlet in the compensation part 2; and a drive source 7, installed in the compensation part 2, the drive source 7 being connected to the other end of the stopper 8, the drive source 7 being used to drive the stopper 8 to slide.
[0023] The connection between the water meter body 1 and the compensation section 2 enables flow compensation while maintaining basic metering. The conical design of the stopper 8 and its sliding within the compensation section 2 allow for precise changes in the diameter of the water inlet within the compensation section 2, thereby flexibly adjusting the water flow rate. The connection between the drive source 7 and the stopper 8 provides stable power for the sliding of the stopper 8, ensuring smooth flow regulation.
[0024] A water channel 201 is provided inside the compensation section 2. The diameters at both ends of the water channel 201 are adapted to the diameter of the water pipe, and the diameter in the middle is larger than the diameter of the water pipe.
[0025] The diameters at both ends of the water channel 201 are matched with the diameter of the water pipe, while the diameter in the middle is larger than that of the water pipe. This allows the water to flow smoothly into and out of the compensation section 2, reducing water flow impact and pressure loss, while also providing ample space for the sliding of the plug 8 and water flow adjustment.
[0026] An auxiliary block 5 is located in the middle of the water channel 201. The diameter of the auxiliary block 5 is smaller than the diameter of the middle part of the water channel 201. An installation groove is provided in the auxiliary block 5 to provide installation space for the drive source 7. A support frame 6 is located between the auxiliary block 5 and the water channel 201. The support frame 6 is used to connect the auxiliary block 5 in the water channel 201.
[0027] The auxiliary block 5 provides installation space for the drive source 7, thus protecting the drive source 7 and ensuring its accurate installation position. The support frame 6 connects the auxiliary block 5 to the water channel 201, thus ensuring the stability of the entire structure and preventing the auxiliary block 5 from shifting due to water flow impact.
[0028] The threaded rod 9 is stably connected at one end to the output end of the drive source 7, and the other end is threadedly connected to the plug 8.
[0029] One end of the threaded rod 9 is stably connected to the output end of the drive source 7, and the other end is threadedly connected to the plug 8, which realizes the conversion of the rotational motion of the drive source 7 into the linear motion of the plug 8, thereby precisely controlling the position of the plug 8 and accurately adjusting the diameter of the water inlet.
[0030] The flow sensor 4 is installed at the end of the compensation unit 2 away from the water meter body 1. The flow sensor 4 is used to monitor the water flow in the water pipe.
[0031] The flow sensor 4 is installed at the end of the compensation unit 2 away from the water meter body 1, which realizes real-time and accurate monitoring of the water flow in the water pipe and provides reliable data for subsequent flow compensation.
[0032] The protective frame 3 is mounted on the compensation part 2; the data processing unit 10 is installed inside the protective frame 3, and the data processing unit 10 is electrically connected to the flow sensor 4, the drive source 7 and the water meter body 1 respectively.
[0033] The protective frame 3 is set on the compensation section 2 to protect the data processing unit 10, thereby preventing the data processing unit 10 from being affected by external environmental factors (such as dust, water vapor, collision, etc.). The data processing unit 10 is electrically connected to the flow sensor 4, the drive source 7 and the water meter body 1, thereby achieving the effect of real-time monitoring, analysis and compensation control of water flow.
[0034] The water flow rate between the auxiliary block 5 and the water channel 201 per unit time is matched with the water flow rate of the water pipe per unit time.
[0035] The water flow rate between the auxiliary block 5 and the water channel 201 per unit time is matched with the water flow rate of the water pipe per unit time, which ensures that the water flows evenly and stably in the compensation section 2, avoids sudden changes in water flow and local pressure anomalies, and improves the accuracy and reliability of compensation.
[0036] The water channel 201 is conical in shape at one end of the outlet of the compensation section 2 and the transition zone in the middle of the water channel 201.
[0037] The water channel 201 is conical at one end of the outlet of the compensation section 2 and the transition zone in the middle of the water channel 201. This allows the water flow to gradually change its speed and direction as it flows out, reducing water flow impact and vortex, ensuring a smooth water flow, and further improving the compensation effect.
[0038] During use, when water flows into the compensation unit 2 through the water pipe, the flow sensor 4 installed at the end of the compensation unit 2 away from the water meter body 1 begins to monitor the water flow in the water pipe in real time. At the same time, the water meter body 1 also performs preliminary measurement of the passing water flow. The flow sensor 4 transmits the monitored water flow data and the preliminary measurement data from the water meter body 1 to the data processing unit 10 installed in the protective frame 3. After receiving these two sets of data, the data processing unit 10 performs comprehensive analysis according to the preset program and algorithm. It compares the real-time flow measured by the flow sensor 4 with the measurement data of the water meter body 1 to determine whether there is a measurement error caused by factors such as unstable water flow and water pressure changes, and then determines whether water flow compensation is needed and the specific degree of compensation. If the analysis determines that compensation is needed, the data processing unit 10 will immediately send a command to the drive source 7 installed in the mounting slot of the auxiliary block 5 in the compensation unit 2. After the drive source 7 is started, its output end drives the stable connection with it. The threaded rod 9 rotates; since the other end of the threaded rod 9 is threadedly connected to the plug 8, the rotation of the threaded rod 9 is converted into the linear sliding of the plug 8 in the compensation section 2; one end of the plug 8 is conical, and the maximum diameter of its conical end is adapted to the water inlet in the compensation section 2; the plug 8 changes the diameter of the water inlet in the compensation section 2 during the sliding process, thereby precisely adjusting the water flow rate; in this process, the diameters of both ends of the water channel 201 are adapted to the diameter of the water pipe, ensuring that the water flow can smoothly enter and exit the compensation section 2, and its larger central diameter provides sufficient space for the sliding of the plug 8; the water flow rate per unit time between the auxiliary block 5 and the water channel 201 is adapted to the water flow rate per unit time of the water pipe, ensuring that the water flow can flow evenly and stably in the compensation section 2; the water channel 201 is located at the water outlet end of the compensation section 2 and the middle of the water channel 201 is conical, so that the water flow can smoothly flow out of the compensation section 2; the water flow after being precisely adjusted by the compensation section 2 finally enters the water meter body 1 for measurement.
[0039] The figures shown in the accompanying drawings are illustrative and are intended only to more intuitively demonstrate the key structure and connection relationships of the smart water meter data metering compensation device of this utility model. In practical applications, the appearance and size of the device can be adjusted and optimized according to specific needs.

To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.
[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
