Description

Technical Field

[0001] This utility model relates to an ultrasonic water meter, and more particularly to an ultrasonic water meter with a mechanical counter. Background Technology

[0002] With the development of smart city construction and refined water resource management, ultrasonic water meters are gradually becoming a replacement for traditional mechanical water meters due to their advantages such as high precision, no mechanical wear, and wide range. Existing ultrasonic water meters typically employ a purely electronic metering system, using ultrasonic sensors to detect water flow velocity and calculate flow rate. The data is displayed in real-time on an electronic display screen and stored in a built-in memory. However, this fully electronic design has significant technical drawbacks: when the water meter malfunctions due to electronic component failure (such as circuit board damage, power outage, or sensor failure) or external interference (such as electromagnetic interference), its electronic display screen and storage system may completely shut down, resulting in the loss of historical flow data prior to the malfunction. This defect not only affects users' ability to trace abnormal water usage (such as leak detection and evidence of water theft) but also leads to the loss of crucial data in metering disputes, negatively impacting the operational efficiency and economic interests of water supply management companies.

[0003] Therefore, a highly reliable solution is urgently needed to address the data backup issue. This solution should maintain the high accuracy advantage of ultrasonic water meters while achieving data preservation before and after a failure through innovative structural design. This patent proposes integrating an independent mechanical counter into the electronic metering system of an ultrasonic water meter. When the electronic system is working normally, flow data is synchronously recorded to the mechanical counter. When the electronic system fails, the mechanical counter can still independently provide the cumulative flow data before the failure, thus overcoming the data silo problem of purely electronic water meters and providing dual protection for water management. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing an ultrasonic water meter with a mechanical counter.

[0005] This utility model is achieved through the following technical solution: It provides an ultrasonic water meter with a mechanical counter, including a measuring pipe and a meter head installed on the measuring pipe. An ultrasonic transducer is installed inside the measuring pipe. The meter head includes a casing and an electromagnetic counter and a signal processor installed inside the casing. The ultrasonic transducer is connected to the input circuit of the signal processor, and the output circuit of the signal processor is connected to the electromagnetic counter. The electromagnetic counter adopts an existing structure, including a signal transmitting part, a relay, and a digit wheel counter. The ultrasonic transducer calculates the water flow rate and cumulative flow, and transmits the signal to the signal processor. The signal processor issues a command to activate the relay, which, through mechanical transmission, causes the digit wheel of the digit wheel counter to rotate and count. The digit wheel counter can visually display the cumulative water consumption. The casing includes a lower casing and a cover. The cover is fastened to the lower casing and fixed with bolts. A waterproof partition is installed inside the cover, separating the inner cavity of the cover from the inner cavity of the lower casing. A glass observation window is provided on the top surface of the cover, with the digit wheel of the electromagnetic counter opposite the glass observation window. The lower end of the electromagnetic counter is fixed to the waterproof partition.

[0006] Preferably, a connecting ear plate is provided at the lower end of the electromagnetic counter, and the connecting ear plate is fixed to the waterproof partition by screws.

[0007] Preferably, the bottom surface of the waterproof partition has multiple first mounting grooves, each with a cable outlet hole. A first adapter circuit board is installed within the first mounting groove and sealed with adhesive. The ultrasonic transducer is connected to the first adapter circuit board via wires, and the first adapter circuit board is connected to the signal processor via wires. The wires connecting the signal processor and the ultrasonic transducer are connected via the first adapter circuit board. Because the first adapter circuit board is sealed within the first mounting groove, it effectively isolates water. If the connection is made directly with wires instead of using the first adapter circuit board, the wire insulation may absorb water, causing a short circuit and affecting usability.

[0008] Preferably, the perimeter of the connection between the waterproof partition and the cover is sealed with adhesive.

[0009] Preferably, a first main circuit board and a second main circuit board are fixedly installed inside the cover. The first main circuit board, the second main circuit board and the waterproof partition are arranged in order from top to bottom and are arranged in parallel.

[0010] Preferably, both the first main circuit board and the second main circuit board are provided with through holes for the electromagnetic counter to pass through.

[0011] Preferably, an LCD screen is installed on the first main circuit board, with the LCD screen facing the glass observation window on the cover, and the signal processor is installed on the second main circuit board.

[0012] Preferably, a support column is provided on the bottom surface of the lower housing, and a flange is connected to the lower end of the support column. The lower housing is connected to the measuring pipe through the flange. A central hole is provided on the support column, and the wire connecting the ultrasonic transducer and the first adapter circuit board passes through the central hole.

[0013] Preferably, the bottom surface of the lower housing is provided with two placement slots for placing the battery, which are located on both sides of the support column respectively; the battery is connected to the second main circuit board.

[0014] Preferably, a second mounting groove is provided on the bottom surface of the lower housing, and a cable outlet hole is provided in the second mounting groove. The second adapter circuit board is installed in the second mounting groove and sealed with glue. The second main circuit board is connected to the second adapter circuit board through a wire, and the output wire connected to the second adapter circuit board passes through the cable outlet hole. Since the second adapter circuit board is sealed in the second mounting groove, it can effectively isolate water.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model integrates an independent electromagnetic counter into the electronic metering system of an ultrasonic water meter. When the electronic system is working normally, the flow data is synchronously recorded to the electromagnetic counter. When the electronic system fails, the electromagnetic counter can still independently provide the cumulative flow data before the failure, avoiding the risk of single storage failure. This breaks through the data silo problem of pure electronic water meters and provides dual protection for water management.

[0017] 2. A glass viewing window is provided on the top surface of the watch cover, which can simultaneously read the value of the electromagnetic counter's digital wheel and the data on the LCD screen.

[0018] 3. The electromagnetic counter module can be disassembled and maintained independently, reducing the cost of use. Attached Figure Description

Detailed Implementation

[0027] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0028] like Figure 1-6 As shown, this utility model includes a measuring pipe 1 and a meter head 2 installed on the measuring pipe 1. An ultrasonic transducer is installed inside the measuring pipe 1 using a conventional installation method. The meter head 2 includes a casing and an electromagnetic counter 15 and a signal processor (not shown in the figure) installed inside the casing. The ultrasonic transducer is circuitically connected to the input terminal of the signal processor, and the output terminal of the signal processor is circuitically connected to the electromagnetic counter 15. The electromagnetic counter 15 adopts a conventional structure and includes a signal transmitting part, a relay, and a digit wheel counter. The ultrasonic transducer calculates the water flow rate and cumulative flow and transmits the signal to the signal processor. The signal processor issues a command to activate the relay, which, through mechanical transmission, causes the digit wheel of the digit wheel counter to rotate and count. The digit wheel counter can visually display the cumulative water consumption.

[0029] The watch case includes a lower housing 3 and a cover 18. The cover 18 is fastened to the lower housing 3 and fixed with bolts. A waterproof partition 10 is installed inside the cover 18, separating the inner cavity of the cover 18 from the inner cavity of the lower housing 3.

A first adapter circuit board (not shown in the figure) is installed within the first mounting groove 11 and sealed with adhesive. The ultrasonic transducer is connected to the first adapter circuit board via a wire, and the first adapter circuit board is connected to the signal processor via a wire. The wires connecting the signal processor and the ultrasonic transducer are connected via the first adapter circuit board. Because the first adapter circuit board is sealed within the first mounting groove 11, it effectively isolates water. If the connection were made directly via wires instead of the first adapter circuit board, the wire insulation would absorb water, causing a short circuit and affecting usability. Furthermore, the perimeter of the connection between the waterproof partition 10 and the cover 18 is sealed with adhesive.

[0032] In this embodiment, a first main circuit board 13 and a second main circuit board 12 are fixedly installed inside the cover 18. The first main circuit board 13, the second main circuit board 12, and the waterproof partition 10 are arranged sequentially from top to bottom and are arranged in parallel. Both the first main circuit board 13 and the second main circuit board 12 have through holes for the electromagnetic counter 15 to pass through.

[0033] Furthermore, an LCD screen 16 is mounted on the first main circuit board 13, and the LCD screen 16 is opposite to the glass observation window 17 on the cover 18. The signal processor is mounted on the second main circuit board 12.

[0034] In this embodiment, a support column 4 is provided on the bottom surface of the lower housing 3, and a flange 5 is connected to the lower end of the support column 4. The lower housing 3 is connected to the measuring pipe 1 through the flange 5. Furthermore, a central hole 8 is provided on the support column 4, and the wire connecting the ultrasonic transducer and the first adapter circuit board passes through the central hole 8.

[0035] In this embodiment, two placement slots 6 for accommodating the battery 9 are provided on the bottom surface of the lower housing 3, respectively located on both sides of the support column 4. Furthermore, the battery is electrically connected to the second main circuit board 12.

[0036] In this embodiment, a second mounting groove 7 is provided on the bottom surface of the lower housing 3, and a wire outlet hole is provided on the second mounting groove 7. The second adapter circuit board (not shown in the figure) is installed in the second mounting groove 7 and sealed with glue. The second main circuit board 12 is connected to the second adapter circuit board through a wire, and the output wire connected to the second adapter circuit board passes through the wire outlet hole. Since the second adapter circuit board is sealed in the second mounting groove 7, it can isolate water.

[0037] This invention integrates an independent electromagnetic counter 15 into the electronic metering system of an ultrasonic water meter. When the electronic system is working normally, the flow data is synchronously recorded to the electromagnetic counter 15. When the electronic system fails, the electromagnetic counter 15 can still independently provide the cumulative flow data before the failure, avoiding the risk of single storage failure. This breaks through the data silo problem of pure electronic water meters and provides dual protection for water management.
