Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic water meter technology, specifically relating to an electromagnetic water meter with leakage detection function. Background Technology

[0002] Electromagnetic water meters are metering instruments specifically designed for the actual needs of water supply and usage enterprises. Designed for the water industry, they optimize water supply and usage and ensure accurate water trade metering and settlement. They comply with the new GB / T778-2018 water meter standard. Their unique all-stainless steel casing design ensures safe use in highly polluted and corrosive environments, meeting domestic water meter usage standards. The full-through structure ensures zero pressure loss and wear-free operation. With an ultra-high range ratio, high sensitivity at low flow rates, excellent performance at low flow velocities, and superior performance in ultra-high flow measurement compared to other water meters, they are far superior.

[0003] Water meters require connectors to connect their two ends to the inlet and outlet pipes during installation. Over time, leaks can occur at these connections. Existing water meters with leak detection capabilities often only provide an alarm and cannot address the leak directly, allowing water to continuously leak into the system. This not only wastes water resources but also causes surrounding metal pipes to rust. Therefore, there is an urgent need for an electromagnetic water meter with leak detection functionality.

[0004] A patent with publication number CN219104294U discloses a water meter with a leakage warning function. The meter includes a main body and an inlet pipe and an outlet pipe fixedly connected to the main body. The outer surfaces of the main body, the inlet pipe, and the outlet pipe are all covered with an insulating silicone grease layer. An insulation layer and a water-absorbing layer are sequentially arranged on the outer surface of the insulating silicone grease layer. A leakage warning circuit is located outside the water-absorbing layer, which is made of absorbent paper. The warning circuit includes a power supply and a buzzer. One end of the buzzer is connected in series with the positive terminal of the power supply, and the other end is connected to a first wire. A second wire is connected to the negative terminal of the power supply. Both the first and second wires are located outside the absorbent paper. When a leak occurs, the absorbent paper absorbs the leaked water, making it conductive. This connects the first and second wires, closing the break in the warning circuit and triggering the buzzer to sound an alarm, indicating a leak.

[0005] However, the above solution, after connecting the first and second wires with absorbent paper, only allows for alarm activation via a buzzer and cannot provide emergency repairs for leaking water pipes. This means that from the moment the alarm sounds until maintenance personnel arrive, water will continuously leak from the pipes, leading to water waste, soil erosion, and corrosion of metal pipes, thus shortening the building's lifespan and threatening its structural stability. In practice, its effectiveness is generally limited. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model provides an electromagnetic water meter with leakage detection function.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An electromagnetic water meter with leakage detection function includes an electromagnetic water meter body and water pipes located at both ends of the electromagnetic water meter body; a first flange is fixedly installed at both the input and output ends of the electromagnetic water meter body, and a second flange is fixedly installed on both water pipes, with the first flange and the second flange connected by fasteners; an annular cavity is formed inside the first flange, and the annular cavity communicates with the gap when the first flange and the second flange abut; an annular mounting box is fixedly connected to and a sensor assembly is fixedly installed inside the annular cavity, and an annular water-absorbing resin is fixedly installed inside the annular mounting box; annular channels are correspondingly formed on the opposing sides of the first flange and the second flange, and an annular airbag is fixedly installed in the annular channel formed by the first flange, with the annular mounting box communicating with the annular airbag.

[0009] Furthermore, the fasteners include bolts and nuts, and a plurality of through holes are provided on the first flange and the second flange respectively. The bolts slide through the through holes on the first flange and the second flange and are threadedly engaged with the nuts.

[0010] Furthermore, the inner wall of the annular mounting box has several through holes, and the annular mounting box communicates with the annular cavity through the several through holes.

[0011] Furthermore, the electromagnetic water meter body is equipped with a buzzer alarm, and the sensor assembly is electrically connected to an external PLC controller. The external PLC controller is electrically connected to both the buzzer alarm and the wireless communication module.

[0012] Furthermore, the annular mounting box is connected to the interior of the annular airbag via a connecting pipe.

[0013] Furthermore, a sealing strip is fixedly installed on the inner wall of the first flange, and a placement groove adapted to the sealing strip is opened on the second flange.

[0014] This application has the following beneficial effects:

[0015] When a leak occurs, the sensor assembly detects the leak and promptly sends an alarm. Simultaneously, the annular absorbent resin absorbs water and expands rapidly, pushing the gas inside the annular mounting box into the annular airbag, causing it to expand and thus blocking the water leaking out of the pipe. This prevents further water leakage, avoids water waste, and better protects the stability of the building structure, resulting in greater practicality. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: An electromagnetic water meter with leakage detection function includes an electromagnetic water meter body 1 and water pipes 4 located at both ends of the electromagnetic water meter body 1. The input end and the output end of the electromagnetic water meter body 1 are both fixedly provided with a first flange 2. The two water pipes 4 are fixedly provided with a second flange 3 at one end facing the electromagnetic water meter body 1. The first flange 2 and the second flange 3 are connected by fasteners.

[0025] The fasteners include bolts and nuts. Several through holes are opened on the first flange 2 and the second flange 3 respectively. The bolts slide through the through holes on the first flange 2 and the second flange 3 and are threadedly engaged with the nuts.

[0026] An annular cavity is provided inside the first flange 2, and the annular cavity is connected to the gap when the first flange 2 and the second flange 3 abut against each other. An annular mounting box 10 is fixedly installed inside the annular cavity, and a sensor assembly 8 is fixedly installed therein. A certain gap is left between the annular mounting box 10 and the bottom inner wall of the annular cavity, and the sensor assembly 8 is embedded in the bottom inner wall of the annular cavity.

[0027] Furthermore, such as Figure 3 As shown, the inner wall of the annular mounting box 10 has several through holes, and the annular mounting box 10 is connected to the annular cavity through the several through holes.

[0028] Furthermore, a buzzer alarm is installed on the electromagnetic water meter body 1, and the sensor assembly 8 is electrically connected to an external PLC controller. The external PLC controller is electrically connected to both the buzzer alarm and the wireless communication module.

[0029] Sensor assembly 8, buzzer alarm, external PLC controller and wireless communication module are all existing technologies and will not be described in detail in this application.

[0030] When a leak occurs, the water in pipe 4 will flow into the annular cavity through the gap between the first flange 2 and the second flange 3. After the sensor assembly 8 in the annular cavity detects the water, it will transmit a signal to the external PLC controller. After receiving the signal, the external PLC controller will, on the one hand, control the buzzer to sound an alarm, and on the other hand, upload the signal to the external control terminal through the wireless communication module to remind the maintenance personnel.

[0031] In addition, an annular water-absorbing resin 9 is fixedly installed inside the annular mounting box 10; annular channels 11 are opened on the opposing sides of the first flange 2 and the second flange 3, and when the first flange 2 and the second flange 3 abut, the annular channel 11 on the first flange 2 is connected to the annular channel 11 on the second flange 3; an annular airbag 6 is fixedly installed inside the annular channel 11 opened in the first flange 2, and the annular mounting box 10 is connected to the interior of the annular airbag 6 through the connecting pipe 7.

[0032] Furthermore, after the annular channel 11 on the first flange 2 is connected to the annular channel 11 on the second flange 3, the space enclosed by them is slightly larger than the annular airbag 6.

[0033] In addition, a sealing strip 5 is fixedly installed on the inner wall of the first flange 2, and a placement groove adapted to the sealing strip 5 is opened on the second flange 3.

[0034] By setting the sealing strip 5, the interface of the electromagnetic water meter body 1 can be sealed, thereby preventing water leakage from the electromagnetic water meter body 1 and improving the sealing performance of the device.

[0035] Working principle: During installation, the two ends of the electromagnetic water meter body 1 are connected to the water pipe 4 through the first flange 2 and the second flange 3. The sealing strip 5 fixed on the first flange 2 abuts against the placement groove opened in the second flange 3 to achieve the sealing effect at the interface of the electromagnetic water meter body 1.

[0036] When the electromagnetic water meter body 1 leaks, that is, when the water in the pipe passes through the sealing strip 5 and flows out of the pipe under the action of the water pressure in the pipe.

[0037] As the water flows outwards, it passes through the annular cavity created by the first flange 2. Upon entering the annular cavity, the water first enters the gap between the annular mounting box 10 and the annular cavity. At this point, the water comes into contact with the sensor assembly 8, which transmits a signal to the external PLC controller. Upon receiving the signal, the external PLC controller simultaneously activates a buzzer alarm and uploads the signal to an external control terminal via a wireless communication module to alert maintenance personnel.

[0038] Subsequently, water flowing into the annular cavity enters the annular mounting box 10 through the through-hole and comes into contact with the annular absorbent resin 9 inside the annular mounting box 10. The annular absorbent resin 9 absorbs water and expands rapidly, thereby pushing the air inside the annular mounting box 10 from the connecting pipe 7 into the annular airbag 6. This causes the annular airbag 6 to inflate and expand, thus sealing the annular channel 11 and preventing water from leaking out of the pipe. This prevents further water leakage, avoids water waste, and better protects the stability of the building structure, thus improving its practicality.

[0039] (It should be noted that after water enters the annular mounting box 10 through the through hole, there will be water at the connection between the annular mounting box 10 and the annular cavity. The water will liquid seal the through hole, so that the air in the annular mounting box 10 can only enter the annular airbag 6 through the connecting pipe 7.)

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
