Technical Field
[0001] The utility model relates to the technical field of cold water meters, in particular to a rotary piston large-caliber direct-reading remote-transmission cold water meter. Background Art
[0002] With the acceleration of urbanization, the management and monitoring of water resources are becoming increasingly important social needs. Traditional water meters have limitations in functionality and accuracy, making them difficult to meet the water management needs of modern households and industries. Therefore, the development of more efficient and accurate water metering equipment is particularly important.
[0003] Although traditional water meters are still widely used in daily life, they face the following limitations:
[0004] Insufficient accuracy: The measurement accuracy of mechanical water meters is affected by flow rate and water quality, and errors are prone to occur.
[0005] Frequent maintenance: Due to the complex internal mechanical structure, traditional water meters require regular maintenance and cleaning to maintain their performance.
[0006] Unable to monitor remotely: Traditional water meters usually require manual meter reading, which makes it impossible to achieve real-time data monitoring and remote management, resulting in high management costs.
[0007] Therefore, it is very necessary to invent a rotary piston large-caliber direct-reading remote cold water meter. Utility Model Content
[0008] In order to solve the above technical problems, the utility model provides a rotary piston large-diameter direct-reading remote-transmitting cold water meter to solve the problem that the existing cold water meter structure still has the problem of being unable to filter impurities in the water passing through the water meter, the filtered impurities cannot be quickly discharged, and the downtime is long during maintenance. A rotary piston large-diameter direct-reading remote-transmitting cold water meter includes a water meter housing, a gear cavity, a dial, a water inlet end, a water outlet end and a third blocking structure, wherein: the gear cavity is fixedly mounted above the water meter housing, and the dial is fixedly mounted above the gear cavity; the water inlet end is fixedly mounted at one end of the water meter housing, and the water outlet end is fixedly mounted at the other end of the water meter housing; the third blocking structure is fixedly mounted inside the water outlet end.
[0009] The water inlet end includes a water inlet pipe, a connecting flange, a water filtering structure, a backwash inlet, a backwash outlet, a first blocking structure and a second blocking structure, and the water inlet pipe is fixedly installed at one end of the water meter housing, and the connecting flange is fixedly installed at the other end of the water inlet pipe; the water filtering structure is fixedly installed in the middle position of the water inlet pipe, and the backwash inlet and backwash outlet are respectively fixedly installed below the water inlet pipe and located at both ends of the water filtering structure; the backwash inlet is located at one end close to the water filtering structure of the water meter housing, and the backwash outlet is located at one end away from the water filtering structure of the water meter housing; the first blocking structure is fixedly installed at one end of the inside of the water inlet pipe away from the water meter housing, and the second blocking structure is fixedly installed at one end of the inside of the water inlet pipe close to the water meter housing.
[0010] The first blocking structure includes an air guide support tube, a blocking air bag, a valve and an air inlet and outlet, and the air guide support tube is fixedly installed inside the water inlet pipe and the water outlet end, and the blocking air bag is fixedly installed at the inner end of the air guide support tube; the valve is fixedly installed at the outer end of the air guide support tube, and the air inlet and outlet are fixedly installed at one end of the valve.
[0011] The water inlet adopts a metal pipe, and the length of the water inlet end is greater than that of the water outlet end, and the water inlet end can block the water flow through the expansion of the first blocking structure and the second blocking structure. The water filtering structure adopts a group of cylindrical filter elements; the backwash inlet and backwash outlet are blocked by a cover during daily use, and the backwash inlet and backwash outlet are opened when backwashing is in progress, and the backwash inlet is connected to the water inlet pipe at one end. Compared with the existing technology, it has the following advantages: ① Enhanced filtering function: The water filtering structure in the water inlet adopts a cylindrical filter element design, which can more effectively filter impurities in the water and avoid damage to the inside of the water meter. This is more durable and has better filtering effect than the traditional simple filter design. Extends the service life of the water meter; ② Backflush cleaning function: The water inlet is equipped with a backflush inlet and backflush outlet, which can be used to clean the water filtration structure by backflush when needed, reducing the maintenance frequency and the complexity of the cleaning operation. This function is usually not available in traditional water meters, which significantly improves the convenience and maintenance efficiency of the equipment; ③ Water flow blocking control: The first blocking structure and the second blocking structure in the water inlet can achieve precise control of the water flow through expansion and contraction. This innovative design allows the water meter to not only operate normally, but also effectively block the water flow for maintenance or backflush cleaning when needed. Traditional water meters generally cannot control the water flow so flexibly and usually need to completely shut down the water source for maintenance.
[0012] The internal structure of the first blocking structure is exactly the same as that of the second blocking structure and the third blocking structure; the blocking airbag inside the first blocking structure can be expanded by injecting high-pressure gas from the air inlet and outlet; the first blocking structure, the second blocking structure and the third blocking structure can form three situations by swelling and deflation; when the first blocking structure, the second blocking structure and the third blocking structure are all deflated, the water meter can be used normally; when the first blocking structure and the second blocking structure are swollen, an independent space can be formed between them, and the water flow will be blocked, and the water filtration structure performs backflushing at this time; when the first blocking structure and the third blocking structure are swollen, the water flow at both ends of the water meter is blocked, and after opening the backflushing inlet and the backflushing outlet, the water in contact with the water meter can be discharged, which has the following advantages compared with the prior art: ① Normal use state: when the first blocking structure, the second blocking structure and the third blocking structure are swollen, the water flow at both ends of the water meter is blocked, and after opening the backflushing inlet and the backflushing outlet, the water in contact with the water meter can be discharged. When the first and second sealing structures are fully deflated, water can flow through the meter normally, allowing flow measurement to continue as normal. Compared to the single-flow mode of conventional water meters, this design provides an optional blocking control function without affecting flow measurement. (2) Partial Water Flow Blockage: In this state, the first and second blocking structures inflate to form a separate, enclosed space, blocking water flow and allowing backflushing. Existing technologies typically require shutting down the entire water filter or system. This design, however, only partially blocks water flow by inflating the airbag, eliminating the need to shut down the entire system. This reduces operational complexity, water outage duration, and user impact. (3) Complete Water Flow Blockage: In this state, the first and third blocking structures inflate, completely blocking water flow from the inlet and outlet pipes. This design is suitable for completely isolating water flow at both ends of the meter. In this state, the backflushing inlet and outlet can be opened to drain accumulated water from the meter, enabling comprehensive drainage and cleaning, and preventing damage to the meter from freezing due to low-temperature conditions.
[0013] The outer side of the dial is rotatably mounted on the dial protection housing.

The setting of the water inlet end of the utility model has the following advantages compared with the existing technology: ① Enhanced filtration function: The water filtration structure in the water inlet end adopts a cylindrical filter element design, which can more effectively filter impurities in the water and avoid damage to the inside of the water meter. This is more durable and has better filtration effect than the traditional simple filter screen design, extending the service life of the water meter; ② Backflush cleaning function: The water inlet end is equipped with a backflush inlet and a backflush outlet, which can be used to clean the water filtration structure by backflush when needed, reducing the maintenance frequency and the complexity of the cleaning operation.

[0016] 2. The setting of the first blocking structure of the present invention has the following advantages compared with the prior art:

[0027] The first blocking structure 56 includes an air guide support tube 561, a blocking air bag 562, a valve 563 and an air inlet and outlet 564, and the air guide support tube 561 is fixedly installed inside the water inlet pipe 51 and the water outlet end 6, and the blocking air bag 562 is fixedly installed at the inner end of the air guide support tube 561; the valve 563 is fixedly installed at the outer end of the air guide support tube 561, and the air inlet and outlet 564 is fixedly installed at one end of the valve 563.
[0028] The water inlet end 5 adopts a metal pipe, and the length of the water inlet end 5 is greater than the length of the water outlet end 6, and the water inlet end 5 can block the water flow through the expansion of the first blocking structure 56 and the second blocking structure 57. The water filtering structure 53 adopts a group of cylindrical filter elements; the backwash inlet 54 and the backwash outlet 55 are sealed by a cover during daily use, and the backwash inlet 54 and the backwash outlet 55 are opened when the backwash work is performed, and the water inlet pipe is connected at one end of the backwash inlet 54.
[0029] The internal structure of the first blocking structure 56 is exactly the same as that of the second blocking structure 57 and the third blocking structure 7; the blocking airbag 562 inside the first blocking structure 56 can be expanded by injecting high-pressure gas from the air inlet and outlet 564; the first blocking structure 56, the second blocking structure 57 and the third blocking structure 7 can form three situations by swelling and deflation; when the first blocking structure 56, the second blocking structure 57 and the third blocking structure 7 are all deflated, the water meter can be used normally; when the first blocking structure 56 and the second blocking structure 57 are swollen, an independent space can be formed between them, and the water flow will be blocked.

[0030] The outer side of the dial 3 is rotatably mounted on the dial protection case 4 .
[0031] 1. The rotary piston large-diameter direct-reading remote cold water meter in this case has significant advantages over existing technologies in a number of design innovations, including:
[0032] 1. Filtration and cleaning functions
[0033] The water filtering structure 53 adopts a cylindrical filter element, which can effectively filter impurities in the water and reduce damage to the inside of the water meter. At the same time, the backflush inlet 54 and backflush outlet 55 allow regular cleaning, which improves the convenience and efficiency of maintenance.
[0034] Existing technologies often only have simple filtering functions, lack effective backwash cleaning design, have high maintenance costs and are complex to operate.
[0035] 2. Flexibility of water flow control
[0036] The design of the first blocking structure 56, the second blocking structure 57 and the third blocking structure 7 can form three water flow states: normal flow, partial blocking and complete blocking. This design allows users to flexibly select the operation mode according to their needs, thereby improving the adaptability of the water meter.
[0037] Traditional water meters usually only have a single water flow mode, lack flexible water flow control, and cannot effectively respond to different usage scenarios.
[0038] 3. Enhanced sealing performance
[0039] The combined design of the blocking airbag 562 and the air guide support tube 561 in the first blocking structure 56 achieves higher sealing performance through gas expansion, which can effectively prevent water leakage and ensure the safe operation of the water meter.
[0040] In contrast, mechanical seals in existing technologies often suffer from wear problems, resulting in poor sealing effects and prone to leakage and failure.
[0041] 4. Structural durability
[0042] The water inlet end 5 adopts a metal pipe, which has excellent corrosion resistance and strength and is suitable for long-term use.
[0043] Traditional water meters are mostly made of plastic or low-quality metal materials, which are easily affected by the environment and have a short service life.
[0044] 5. Reduce maintenance costs
[0045] This design allows backwash cleaning to be performed without shutting off the entire water source, significantly reducing the manpower and time costs during maintenance. This function is especially suitable for situations where frequent maintenance is required.
[0046] Existing technologies often require completely shutting off the water source or dismantling the equipment for cleaning, which is cumbersome and time-consuming.
[0047] 6. Operational safety and automation potential
[0048] The coordinated use of the first blocking structure 56 and other blocking structures can realize automatic water flow control, reduce manual intervention, and improve safety and automation potential.
[0049] The operation of traditional water meters relies on manual labor, which is relatively unsafe and prone to human errors.
[0050] 2. Usage process
[0051] 1. Turn on the computer
[0052] Make sure the water inlet 5 and water outlet 6 valves are open.
[0053] Check whether the pointer of dial 3 is reset to zero to confirm that the device is in normal condition.
[0054] 2. Normal use
[0055] In daily use, water flows into the water meter through the water inlet 5, and the water filtering structure 53 filters impurities in the water to ensure the cleanliness of the water.
[0056] The rotary piston rotates according to the water flow rate, and the dial 3 displays the water usage in real time.
[0057] 3. Backflush cleaning
[0058] When the water flow rate drops significantly or the water quality is poor, backflushing can be performed.
[0059] Open the covers of the backflushing inlet 54 and the backflushing outlet 55 and start the backflushing function. The system will automatically clean the water filtering structure 53 to ensure the normal operation of the equipment.
[0060] 4. Maintenance and inspection
[0061] Check the connections regularly to ensure there are no water leaks.
[0062] At regular intervals, the first blocking structure 56, the second blocking structure 57 and the third blocking structure 7 are inspected to ensure that the sealing performance is good.
[0063] 5. Turn off the device
[0064] When not in use, it is recommended to close the valves at the water inlet 5 and the water outlet 6 to ensure that the equipment is in a safe state.
[0065] 3. Summary
[0066] Through the aforementioned innovations and optimizations, the large-diameter rotary piston direct-reading, remote-transmitting cold water meter in this case offers significant advantages over existing technologies in terms of filtration and cleaning capabilities, flexible water flow control, sealing performance, structural durability, maintenance costs, and operational safety. These designs not only enhance the meter's performance and reliability, but also significantly reduce user costs and risks during maintenance and use.
[0067] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
