[0031] The ultrasonic pipe section detection assembly 100 includes an ultrasonic pipe section 101.

The detection ends of the residual chlorine detector 205 and the pH detector 206 are inserted into the ball valve pipe section 203a and come into contact with the water flow. The detection tube 204 is screwed to the ball valve vertical pipe 203b. The residual chlorine detector 205 and the pH detector 206 are screwed to their respective detection tubes 204.

[0034] The sealing cover 400 includes an upper cover 401, a motor plastic cover 402, and a bottom cover 403, with a battery for powering all components housed in the bottom cover 403.

[0035] It should be noted that the temperature sensor 103, pressure sensor 104, residual chlorine detector 205, and pH detector 206 all use existing conventional sensors, which will not be elaborated on here.

[0036] It should be noted that the ultrasonic transducer assembly 102 measures the corresponding parameters using existing ultrasonic signal measurement principles.

[0037] It should be noted that in this utility model: temperature parameters are detected by a temperature detector; pressure parameters are detected by a pressure detector; residual chlorine parameters are detected by a residual chlorine detector; pH parameters are detected by a pH detector; instantaneous flow parameters are detected by an ultrasonic transducer; and cumulative flow parameters are detected by an ultrasonic transducer.

[0038] Specifically:

[0039] From the perspective of the two parameters, "instantaneous flow rate" and "cumulative flow rate", this solution uses the ultrasonic transducer assembly in the overall ultrasonic measurement structure for measurement. From the perspective of the detection device itself, it can realize both ultrasonic detection and valve control functions.

[0040] From the perspective of the two parameters "temperature" and "pressure", this solution uses ultrasonic measurement of the temperature sensor 103 and pressure sensor 104 in the overall structure for measurement;

[0041] In terms of the two parameters, "residual chlorine parameter" and "pH value parameter", this solution uses residual chlorine detection component 201 and pH value detection component 202 for measurement. The relevant sensors are installed in the back-end structure, and the configured switching valve prevents water spraying when replacing the sensors.

[0042] Specifically, filters are installed at both the inlet and outlet of the ultrasonic pipe section 101;

[0043] The inlet is equipped with a mesh filter and the outlet is equipped with a cross-shaped filter.

[0044] The other end of the ball valve pipe section 203a is equipped with a mesh filter.

[0045] Filter screens are used for the initial filtration of water.

[0046] Specifically, the pressure sensor 104 is screwed into the pressure sensor mounting hole through a pipe section transfer nut, and a sealing O-ring is also provided at the connection between the transfer nut and the pressure sensor mounting hole.

[0047] Specifically, the temperature sensor 103 is inserted into the temperature sensor mounting hole through a small sleeve, and a sealing O-ring is provided at the junction of the small sleeve and the temperature sensor mounting hole.

[0048] Specifically, the ultrasonic transducer assembly 102 includes a receiving member 102a, in which a ceramic wafer 102b is disposed, and a rubber pad 102c is placed on the ceramic wafer 102b. A connecting member 102d connects to the receiving member 102a to realize the closed housing of the ceramic wafer 102b and the rubber pad 102c. A sealing nut is also provided on the receiving member 102a, and a sealing O-ring is provided at the junction of the sealing nut and the ultrasonic transducer mounting hole. A sealing O-ring is also provided at the junction of the receiving member 102a and the ultrasonic transducer mounting hole.

[0049] It should also be noted that, in order to make the ultrasonic transducer assembly 102 and pressure sensor 104 more securely installed and the overall ultrasonic detection structure more complete, a pipe section cover plate is usually installed after the series sensors are installed into the corresponding ultrasonic pipe section 101 top mounting hole, as shown in the attached figure. Alternatively, it can be omitted without affecting the overall function.

[0050] Specifically, a sealing O-ring is provided at the connection between the detection tube 204 and the ball valve riser tube 203b.

[0051] Specifically, the ball valve 203c is equipped with PTFE rings at both the top and bottom, and a sealing O-ring is also installed at the bottom where it connects with the ball valve pipe section 203a.

[0052] Specifically, a steel sleeve retaining ring 207 is screwed to the bottom of the detection tube 204, and the diameter of the steel sleeve retaining ring 207 is larger than the top diameter of the ball valve riser 203b.

[0053] Specifically, a sealing O-ring is also provided at the screw connection between the steel sleeve retaining ring 207 and the detection tube 204.

[0054] Additionally, the adapter board 105b is also embedded with a microprocessor for filtering noise waveforms, which is connected to the ultrasonic transducer assembly 102. The microprocessor includes a pulse sampling unit, a filtering unit, and a flow totalization unit. Each unit can be implemented using a chip or integrated circuit with corresponding functions. The microprocessor is connected to the signal transmitting transducer via a signal transmitting transducer lead and to the signal receiving transducer via a signal receiving transducer lead.

[0055] See Figure 6 This is a flowchart illustrating the signal processing of the microprocessor involved in this utility model. The ultrasonic pulse emitted by the signal transmitting transducer at a certain time point has only one peak. When the ultrasonic wave encounters impurities in the fluid, the angle of incidence shifts. When the ultrasonic wave is received by the signal receiving transducer, its amplitude and peak shape differ from the original shape, resulting in a change in the shape of the emitted wave peak. Within the sampling number corresponding to the emitted wave peak, the pulse sampling unit detects multiple peaks. The filtering unit compares the peak amplitude values, selects the peak with the largest amplitude, obtains the maximum peak of the received wave within that sampling number, and the corresponding time point, which is then transmitted to the flow totalization unit.

[0056] The signal transmitting transducer emits a pulse signal, which passes through the fluid in the pipe and is received by the signal receiving transducer. The pulse sampling unit performs pulse sampling on the signal received by the signal receiving transducer, and obtains multiple peaks within the sampling time. The filtering unit determines the maximum peak and the corresponding time point based on the multiple peaks within the sampling time and transmits them to the flow totalization unit for flow calculation to obtain the flow value.

[0057] Preferably, in order to securely install the ball valve riser 203b into the ball valve pipe section 203a, in addition to a set of screws, a valve connector is generally designed at the bottom of the ball valve riser 203b, as shown in the figure. However, the absence of this structure does not affect the realization of the overall structure.

[0058] During use, when water is turned on and the measurement is activated, the residual chlorine detection component 201, pH value detection component 202, temperature sensor 103, and pressure sensor 104 transmit the detected parameters to the signal display screen 300 for display.

[0059] Especially when it is necessary to replace the residual chlorine detector 205 and the pH detector 206: keep the water flowing, unscrew the ball valve riser 203b of the detection tube 204 and lift it upward. During this process, the steel sleeve retaining ring 207 will block the gushing water flow. After lifting it to a certain extent, turn the ball valve 203c to shut off the upward water flow, and then unscrew the detector from the corresponding detection tube to complete the replacement. In this process, the ingenious structural design prevents water spraying when replacing the sensor.

[0060] This utility model provides a multifunctional water supply terminal. It employs an ultrasonic transducer assembly within an ultrasonic measurement system to perform dual-parameter measurement of instantaneous and cumulative flow. From the perspective of the detection device itself, it can realize both ultrasonic detection and valve control functions. Specifically, a filtering algorithm is used to process the flow monitoring data. By sampling and filtering the received ultrasonic waveform, accurate ultrasonic peaks are obtained, eliminating the commonly used first-wave measurement in the industry and removing measurement deviations caused by impurities in the fluid, thus improving the accuracy and real-time performance of the monitoring data. Temperature and pressure sensors within the ultrasonic measurement system are used for dual-parameter measurement of temperature and pressure. Residual chlorine and pH detection components are used for dual-parameter measurement of residual chlorine and pH parameters. Furthermore, the relevant sensors are installed in the rear-end structure, and the configured switching valve prevents water spraying during sensor replacement, solving the problem of existing water supply detection equipment lacking the ability to detect other water quality parameters.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
