Description

Technical Field

[0001] This application relates to the technical field of fluid metering equipment, and in particular to an electromagnetic water meter with turbidity measurement function. Background Technology

[0002] In recent years, electromagnetic water meters have been widely used in municipal water supply networks due to their direct-flow characteristics and high-precision measurement capabilities. These meters not only effectively monitor water flow but also serve as an important tool in water supply network management due to their excellent performance. However, with increasingly stringent requirements for municipal water quality monitoring, relying solely on electromagnetic water meters for flow monitoring is no longer sufficient to meet practical needs.

[0003] To meet the comprehensive needs of water quality monitoring, tap water networks typically require the installation of a series of additional devices to measure key parameters such as residual chlorine, turbidity, and pH value. The addition of these devices undoubtedly increases the overall cost of the system, encompassing not only the purchase price of the equipment itself but also expenses for installation, commissioning, and subsequent maintenance. Utility Model Content

[0004] In order to enable the electromagnetic water meter to measure turbidity simultaneously, this application provides an electromagnetic water meter with turbidity measurement function.

[0005] The electromagnetic water meter with turbidity measurement function provided in this application adopts the following technical solution:

[0006] An electromagnetic water meter with turbidity measurement function includes a housing, which is fixed outside a pipe and has an electromagnetic sensor installed on it. The housing also has a turbidity detection mechanism and a converter mechanism. The turbidity detection mechanism includes a turbidity sensor, the probe of which is located inside the pipe. Both the electromagnetic sensor and the converter mechanism are electrically connected.

[0007] By adopting the above technical solution, while measuring the flow rate of the liquid through the battery sensor, the turbidity of the liquid flowing through it is also measured by setting up a turbidity detector; and the converter mechanism can receive signals from the electromagnetic sensor and the turbidity sensor, and convert these signals into readable data output for users to monitor or record, so as to meet the comprehensive needs of water quality monitoring.

[0008] Preferably, the turbidity detection mechanism further includes a mounting base, which is disposed on the housing. The mounting base has a mounting hole that communicates with the pipe, and the turbidity sensor is inserted into the mounting hole. A locking nut is fitted on the outside of the turbidity sensor, and the inner wall of the mounting hole has a thread that engages with the locking nut.

[0009] By adopting the above technical solution, the mounting base serves as the support structure for the turbidity sensor. Tightening the locking nut ensures that the sensor is stably mounted on the housing, preventing it from shaking or falling off during use, thereby guaranteeing the accuracy and stability of the measurement.

[0010] Preferably, the turbidity sensor is fitted with an elastic sealing sleeve on its outer side, and the elastic sealing sleeve is disposed inside the mounting base.

[0011] By adopting the above technical solution, the elastic sealing sleeve can effectively prevent liquid or gas in the pipeline from leaking out through the tiny gap between the sensor and the mounting base, thereby enhancing the sealing performance of the entire turbidity detection mechanism.

[0012] Preferably, the turbidity sensor is also provided with a protective chain, the other end of which is fixedly installed on the housing.

[0013] By adopting the above technical solution and setting up a protective chain, it can be ensured that the turbidity sensor is not easily dropped from its installation position even under the influence of water flow impact, vibration or other external factors.

[0014] Preferably, the converter mechanism includes a converter housing, a circuit board module, and a battery module. The circuit board module and the battery module are both disposed inside the converter housing. The converter housing is connected to the housing via a conversion disk. The circuit board module is electrically connected to the electromagnetic sensor and the turbidity sensor. The voltage output terminal of the battery module is electrically connected to the power supply terminals of the circuit board module, the electromagnetic sensor, and the turbidity sensor.

[0015] By adopting the above technical solution, the battery module can directly provide power to the circuit board module, electromagnetic sensor and turbidity sensor, which solves the problem of the relatively complex power supply of traditional electromagnetic water meters and can directly provide suitable electrical energy.

[0016] Preferably, the circuit board module includes a current conversion module, a signal processing module, and a communication module. The output terminals of the turbidity sensor and the electromagnetic sensor are electrically connected to the input terminal of the current conversion module, and the output terminal of the current conversion module is electrically connected to the input terminal of the communication module through the signal processing module.

[0017] By adopting the above technical solution, the current conversion module can receive signals from the electromagnetic sensor and the turbidity sensor, and the signal processing module can amplify, filter, and convert these signals into digital signals to obtain accurate flow and turbidity data. Then, the communication module can transmit the flow and turbidity data to external devices for user monitoring.

[0018] Preferably, a display module is also provided inside the converter housing, and the display module is electrically connected to the circuit board module.

[0019] By adopting the above technical solution and setting up a display module, flow rate and turbidity data can be directly displayed on the electromagnetic water meter, making it convenient for users to obtain data intuitively.

[0020] Preferably, the converter housing also includes a remote transmission module, which is signal-connected to the circuit board module, and the remote transmission module includes a remote transmission antenna.

[0021] By adopting the above technical solution, the introduction of the remote transmission module reduces the frequency of manual meter reading and maintenance. Traditional water meters require staff to regularly visit the site for meter reading and maintenance, while electromagnetic water meters with remote transmission capabilities can achieve automated management through remote data transmission. This not only reduces labor costs but also improves work efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By installing an electromagnetic sensor on top of the turbidity sensor on the housing, turbidity measurement and flow measurement can be integrated, simplifying the system complexity and improving measurement accuracy;

[0024] 2. An integrated power supply is achieved by adopting a converter mechanism, which powers not only the electromagnetic sensor but also the turbidity sensor, effectively simplifying the overall structure, reducing the number of external data cables, and facilitating installation and maintenance;

[0025] 3. The design of the mounting base allows the turbidity sensor to be stably inserted into the mounting hole, and the locking nut and elastic sealing ring further improve its fixation and waterproof performance, ensuring the reliability and accuracy of turbidity measurement.

Detailed Implementation

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] This application discloses an electromagnetic water meter with turbidity measurement function.

[0032] Reference Figure 1 , Figure 2 and Figure 3 An electromagnetic water meter with turbidity measurement function includes a housing 1 and an electromagnetic sensor 2 mounted on the housing 1. It also includes a turbidity measuring mechanism 3 and a converter mechanism 4 mounted on the housing 1. The turbidity measuring mechanism 3 includes a turbidity sensor 31, which is mounted at the downstream end of the electromagnetic sensor 2 and is used to measure turbidity. The output terminal of the converter mechanism 4 is electrically connected to the power supply terminal of the electromagnetic sensor 2, and the converter mechanism 4 includes a battery module 42 and a circuit board module 43, thereby enabling integrated power supply for the electromagnetic water meter.

[0033] The housing 1 is cylindrical in shape and is fitted on the outside of the pipe 100. The axis of the housing 1 coincides with the axis of the pipe 100. Both ends of the housing 1 along its length are provided with mounting parts 11 for installing and fixing electromagnetic water meters. In this embodiment, the mounting parts 11 are flanges.

[0034] The turbidity measuring mechanism 3 includes a turbidity sensor 31 and a mounting base 32, with the mounting base 32 mounted on the outer wall of the housing 1. The mounting base 32 is cylindrical, with its axis perpendicular to the axis of the housing 1, and forms a 45° angle with the horizontal planes of the two electrodes of the electromagnetic sensor 2. The mounting base 32 has a mounting hole 321 along its own axis, which communicates with the pipe 100. The turbidity sensor 31 is cylindrical, with its axis coinciding with the axis of the mounting base 32. The turbidity sensor 31 is inserted into the mounting hole 321, with its probe 311 located inside the pipe 100. The tail end of the turbidity sensor 31, away from the probe 311, is located on the outer side of the mounting base 32, away from the housing 1. A locking nut 34 is also fitted on the outside of the turbidity sensor 31. The locking nut 34 is located near the tail end of the turbidity sensor 31 and is located on the outside of the mounting base 32. The inner wall of the mounting hole 321 is provided with a thread that engages with the thread of the locking nut 34, so that the turbidity sensor 31 can be locked and fixed by tightening the locking nut 34.

[0035] In this embodiment, the probe 311 of the turbidity sensor 31 is made of stainless steel. The probe 311 adopts an I-shaped structure with measurement windows on both opposite sides, allowing for multi-directional turbidity detection inside the pipe 100. The turbidity sensor 31 has a built-in measurement light source module, which includes an LED light source and an optical fiber for transmitting the measurement light. A structure with a laser light source can further enhance the focusing of the light source, ensuring accurate acquisition of the turbidity signal. The measurement light source module can be replaced with an LED light source structure with laser focusing function to improve measurement accuracy. When water flows parallel to the probe 311, it can collect turbidity signals, thus achieving turbidity measurement.

[0036] An elastic sealing sleeve 33 is fitted around the outer side of the turbidity sensor 31, and the elastic sealing sleeve 33 is disposed inside the mounting base 32 and close to the outer wall of the housing 1. The elastic sealing sleeve 33 is made of a material with a certain elastic deformation capability, such as silicone or rubber. When the turbidity sensor 31 is inserted into the mounting base 32, the elastic sealing sleeve 33 is in a compressed state, thereby improving the overall waterproof performance and the tightness of the installation of the turbidity sensor 31. In addition, a protective chain 35 is provided at the tail end of the turbidity sensor 31, and the other end of the protective chain 35 is fixedly installed on the mounting part 11 to prevent the turbidity sensor 31 from falling into the pipe 100 as much as possible.

[0037] The converter mechanism 4 also includes a converter housing 41, a remote transmission module 45, and a display module 44. The converter housing 41 is fixedly mounted on the housing 1 via a conversion disk 46, and a sealing ring 47 for improving sealing is provided inside the conversion disk 46. The battery module 42 and the circuit board module 43 are disposed inside one of the converter housings 41, and the display module 44 is disposed on the other converter housing 41, with the two converter housings 41 respectively located on opposite sides of the connecting plate. The turbidity sensor 31 and the electromagnetic sensor 2 are connected to the converter mechanism 4 via a data cable 36, and the converter housing 41 is also provided with a turbidity aviation plug 411 for connecting the data cable 36 to achieve power supply and data transmission functions.

[0038] In this embodiment, the battery module 42 includes multiple lithium batteries, and the output end of the battery module 42 is electrically connected to the power supply end of the turbidity sensor 31 and the electromagnetic sensor 2 through the data cable 36, thereby enabling direct power supply to the turbidity sensor 31 and the electromagnetic sensor 2, and avoiding the complexity of the transmission electromagnetic water meter requiring an external power supply.

[0039] The circuit board module 43 includes a current conversion module, a signal processing module, and a communication module. The current conversion module is connected to the turbidity sensor 31 and the electromagnetic sensor 2, converting the electrical signals collected by the electromagnetic sensor 2 and the turbidity sensor 31 into a standard current signal that is easy to process. The signal processing module amplifies and filters the standard current signal to improve signal stability. The communication module communicates with external devices, enabling the transmission of measured data. The current conversion module can use a high-precision current conversion chip to effectively reduce errors during signal conversion, while the signal processing module can use a processor chip with filtering and amplification functions to ensure signal accuracy and reliability.

[0040] The display module 44 is located on the other side of the connecting plate. The display module 44 includes a display screen and a control panel. The display screen shows turbidity and flow information, while the control panel receives user commands. The display screen can be a backlit LCD screen to ensure clear information display even in low light conditions. The control panel can use a combination of touch buttons or knobs to improve user convenience and operability.

[0041] The remote transmission module 45 and the circuit board module 43 are connected by a signal connection, including a remote transmission antenna. The remote transmission antenna is used to realize wireless communication between the converter and the remote device. The remote transmission antenna can adopt built-in ultra-wideband antenna technology to ensure reliable communication even in complex electromagnetic environments. In addition, the converter housing 41 is also provided with a remote transmission aviation connector 412 for outputting wired signals such as RS485.

[0042] The implementation principle of an electromagnetic water meter with turbidity measurement function in this application embodiment is as follows: by installing a turbidity sensor 31 on the housing 1 on the basis of installing an electromagnetic sensor 2, turbidity measurement and flow measurement can be integrated, which simplifies the complexity of the system and improves the measurement accuracy; at the same time, the converter mechanism 4 is used to realize integrated power supply, which not only powers the electromagnetic sensor 2 but also the turbidity sensor 31, effectively simplifying the overall structure, reducing the number of external data cables 36, and facilitating installation and maintenance.
