Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to an explosion-proof and leakage-detecting automatic shut-off water meter. Background Technique

[0002] A water meter is an instrument used to measure and record water flow, and is widely used in domestic, commercial and industrial water management. It usually consists of a meter body, a measuring mechanism, an indicating device, etc. It measures the water volume passing through the pipeline through the principle of fluid dynamics and provides accurate flow data at any time.

[0003] Generally, the top of the existing water meter is isolated by glass, which is convenient for people to observe the water meter data. However, the glass is relatively fragile, and when the glass is damaged, it will cause water leakage.

[0004] In order to overcome the above defects, a Chinese patent of the prior art (Publication No.: CN205483135U) discloses a water meter that prevents cracking and water leakage. A glass table cover is arranged on the meter body, and an explosion-proof film for sticking the glass to prevent water leakage after the glass is broken is pasted on the outer surface of the glass table cover.

[0005] The above prior art optimizes the structure of the water meter to prevent water leakage when the water meter is damaged. In practical applications, the water meter has a variety of materials and different measurement methods to adapt to different climate environments and different fluids. Its technology has matured, but during use, the water meter cannot monitor the water leakage of the pipeline in time. When the pipeline leaks, the water flow cannot be blocked in time, which is likely to cause waste of water resources. Content of the Utility Model

[0006] The purpose of the utility model is to provide an explosion-proof and leakage-detecting automatic shut-off water meter to solve the problem that the water meter in the above background technology cannot monitor the water leakage of the pipeline in time, and when the pipeline leaks, the water flow cannot be blocked in time, which is likely to cause waste of water resources.

[0007] To achieve the above purpose, the utility model provides the following technical scheme: an explosion-proof and leakage-detecting automatic shut-off water meter, including a housing, a water inlet and a water outlet. The water inlet and the water outlet are both fixedly connected to both sides of the housing, and the water inlet and the water outlet are both communicated with the inside of the housing;

[0008] An isolation ring is fixedly connected to the middle inside the housing, and the isolation ring divides the inside of the housing into upper and lower parts. The water inlet is communicated with the upper half of the housing, and the water outlet is communicated with the lower half of the housing. A telescopic rod is fixedly connected to the bottom of the housing, and the telescopic end of the telescopic rod penetrates through the bottom of the housing and extends towards the inside of the housing. The top of the telescopic end of the telescopic rod is fixedly connected to a sealing disc, and the sealing disc is slidably connected to the inside of the lower half of the housing, and the sealing disc is mutually attached to the bottom of the isolation ring.

[0009] Preferably, a meter is fixedly connected to the upper half inside the outer shell, and the top of the meter is flush with the top of the outer shell. A protective cover is hinged to the outer side of the upper end of the outer shell, and the protective cover is snap-connected to the top of the outer shell and is located on the top of the meter.

[0010] Preferably, an impeller is rotatably connected to the bottom of the meter, and the impeller is composed of paddles distributed at equal intervals in a ring shape. A measuring box is snap-connected to the bottom of the meter.

[0011] Preferably, a mounting ring is fixedly connected to the outer side of the measuring box, and the bottom of the mounting ring is mutually attached to the top of the isolation ring. The measuring box is snap-connected to the inner side of the isolation ring. The part of the measuring box located above the mounting ring is located in the upper half of the outer shell, and the part of the measuring box located at the bottom of the outer shell is located in the lower half of the outer shell.

[0012] Preferably, the measuring box is located outside the impeller, and water inlet holes and water outlet holes distributed at equal intervals in a ring shape are respectively arranged on the outer side of the measuring box. The water inlet holes are located at the top of the mounting ring, the water outlet holes are located at the bottom of the mounting ring, and both the water inlet holes and the water outlet holes are distributed along the tangential direction of the measuring box.

[0013] Preferably, a water pipe is fixedly connected to the end of the water outlet away from the outer shell, and the water outlet and the water pipe are connected to each other through a flange. The water pipes are connected to each other through a flange to form a water path.

[0014] Preferably, conductive wires distributed at equal intervals in a ring shape are fixedly connected to the outer side of the water pipe, and the conductive wires are distributed on the outer side of the water pipe along the extending direction of the water pipe. Both ends of the conductive wires are fixedly connected with transmission rings, and the transmission rings are fixedly connected to the outer side of the water pipe. The transmission rings on the outer sides of the two water pipes are connected to each other through a connecting wire. For the transmission ring on the outer side of the water pipe close to the water outlet, the lower end of this transmission ring is electrically connected to the telescopic rod through a control wire.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] For this explosion-proof and leakage-proof automatic detection and closing water meter, when the water pipe bursts due to its own damage, at this time, water will flow outside the water pipe. When the water flows outside the water pipe, it will form a wire effect between the two conductive wires, causing an electrical connection between the two conductive wires. At this time, the electrical signal of the mutual connection of the two conductive wires will be transmitted to the inside of the control wire through the transmission ring and the connecting wire, and then transmitted to the inside of the telescopic rod through the control wire. At this time, the telescopic rod will drive the sealing disc to move upward in the lower half of the outer shell until the sealing disc slides to the outside of the measuring box to incompletely block the water inlet hole, reducing the water flow rate inside the outer shell and inside the water pipe;

[0017] Further, a remote communication module is provided inside the meter. When the sealing disc incompletely blocks the water inlet hole, while ensuring the minimum supply of water, it prevents excessive waste of water resources. At this time, the meter transmits the water leakage situation of the water pipe to the mobile terminal through the communication module to remind the user, and the electrical signals of the conductive wires on the outer sides of different sections of the water pipe can be numbered, so as to accurately locate the water leakage section of the water pipe;

[0018] Further, when the water pipe breaks, the conductive wire located on the outer side of the water pipe will be completely broken. At this time, the signal generated when the conductive wire breaks will be transmitted into the telescopic rod, and the conductive wire drives the sealing disc to move upward until the sealing disc fits against the bottom of the isolation ring, thereby completely blocking the water inlet hole, preventing water from flowing inside the housing, and further preventing the waste of water resources caused by the breakage of the water pipe.

A protective cover 8 is hinged to the outside of the upper end of the housing 1, and the protective cover 8 is snap-connected to the top of the housing 1, and the protective cover 8 is located on the top of the meter 7.

[0032] The bottom of the meter 7 is rotatably connected with an impeller 9, and the impeller 9 is composed of vanes distributed at equal intervals in a ring shape, and a meter box 10 is snap-connected to the bottom of the meter 7.

[0033] An installation ring 11 is fixedly connected to the outside of the meter box 10, and the bottom of the installation ring 11 is in mutual contact with the top of the partition ring 4. The meter box 10 is snap-connected to the inside of the partition ring 4, and the part of the meter box 10 located above the installation ring 11 is located in the upper half of the housing 1, and the part of the meter box 10 located at the bottom of the housing 1 is located in the lower half of the housing 1.

[0034] The meter box 10 is located outside the impeller 9, and water inlet holes 12 and water outlet holes 13 distributed at equal intervals in a ring shape are respectively arranged on the outside of the meter box 10. The water inlet holes 12 are located on the top of the installation ring 11, and the water outlet holes 13 are located on the bottom of the installation ring 11, and both the water inlet holes 12 and the water outlet holes 13 are distributed along the tangent direction of the meter box 10.

[0037] Embodiment Two:

[0038] On the basis of Embodiment One, its specific working principle is as follows:

[0039] For this explosion-proof and leakage-autodetecting shut-off water meter, during the operation of the water meter, water first flows into the interior of the housing 1 from the water inlet 2. At this time, the water is located in the lower half of the housing 1. The water in the lower half of the housing 1 enters the interior thereof through the water inlet holes 12 on the outer side of the metering box 10, and then flows out of the interior of the metering box 10 through the water outlet holes 13. Since the orientations of both the water inlet holes 12 and the water outlet holes 13 are the tangential directions of the metering box 10, the water will rotate inside the metering box 10 when passing through the interiors of the water inlet holes 12 and the water outlet holes 13, thereby causing the water flow inside the metering box 10 to drive the impeller 9 inside it to rotate. By the rotation of the impeller 9, the internal structure of the meter 7 is driven to rotate, so that the meter 7 measures the water flow rate. The water flowing out of the interior of the metering box 10 will enter the water circuit composed of multiple water pipes 14 through the water outlet 3;

[0040] During the process of water flowing inside the water pipe 14, when the water pipe 14 is damaged and ruptured due to its own reasons, at this time the water will flow on the outer side of the water pipe 14. When the water flows on the outer side of the water pipe 14, it will form a wire effect between the two conductive wires 15, causing an electrical connection to be generated between the two conductive wires 15. At this time, the electrical signal of the mutual connection of the two conductive wires 15 will be transmitted into the control wire 18 through the transmission ring 16 and the connecting wire 17, and transmitted into the telescopic rod 5 through the control wire 18. At this time, the telescopic rod 5 will drive the sealing disk 6 to move upward in the lower half of the housing 1 until the sealing disk 6 slides to the outer side of the metering box 10 to incompletely block the water inlet holes 12, reducing the water flow rate inside the housing 1 and inside the water pipe 14. A remote communication module is provided inside the meter 7. When the sealing disk 6 incompletely blocks the water inlet holes 12, while ensuring the minimum supply of water, it prevents excessive waste of water resources. At this time, the meter 7 transmits the water leakage situation of the water pipe 14 to the mobile terminal through the communication module to remind the user, and the electrical signals of the conductive wires 15 on the outer sides of different sections of the water pipe 14 can be numbered, so as to accurately locate the water leakage section of the water pipe 14;

[0041] When the water pipe 14 breaks, the conductive wire 15 located outside the water pipe 14 will be completely broken. At this time, the signal generated when the conductive wire 15 breaks will be transmitted into the telescopic rod 5. The conductive wire 15 drives the sealing disc 6 to move upward until the sealing disc 6 fits against the bottom of the isolation ring 4, thereby completely blocking the water inlet hole 12 to prevent water from flowing inside the housing 1, and further preventing the waste of water resources caused by the breakage of the water pipe 14.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
