Description

Technical Field

[0001] The present invention relates to the technical field of water meters, and in particular to an intelligent membrane block sealing structure for a NB water meter. Background Art

[0002] Water meters are instruments used to measure water flow, mostly cumulative water flow measurements, and are generally divided into two categories: volumetric water meters and velocity water meters. With the continuous development of information technology, the Internet of Everything has begun. Traditional reading of water meter data requires employees to observe and record one by one, which consumes a lot of manpower and material resources. In order to accurately and real-time calculate water meter data, a processing unit is also set up in the water meter, integrating the water meter into the Internet, and can quickly read data.

[0003] The existing NB smart water meter contains a large number of electronic devices, so a strict sealing and waterproof structure is required. The sealing structure of the existing NB smart water meter is relatively simple and the waterproof effect is poor, which makes the NB smart water meter easy to be penetrated by water and cause damage to the instrument. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a NB water meter intelligent membrane block sealing structure, which solves the problem that the existing NB intelligent water meter has a relatively simple sealing structure and poor waterproof effect, making the NB intelligent water meter easily penetrated by water and causing damage to the instrument.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a NB water meter intelligent membrane block sealing structure, including a rotating chamber, an "n"-shaped sealing ring is arranged on the top of the rotating chamber, a first threaded ring is arranged on the outside of the "n"-shaped sealing ring, the first threaded ring is fixedly connected to the outer wall of the rotating chamber, a smart dial is arranged on the upper part of the rotating chamber, a second threaded ring is fixedly connected to the lower surface of the smart dial, a thread is arranged on the inner wall of the second threaded ring, a thread is provided on the outer wall of the first threaded ring, the thread of the inner wall of the second threaded ring can be engaged with the thread of the outer wall of the first threaded ring, a "human"-shaped sealing ring is arranged inside the second threaded ring, the inner wall of the bottom of the "human"-shaped sealing ring can fit with the upper top surface of the "n"-shaped sealing ring, a humidity measuring device is arranged between the "human"-shaped sealing ring and the second threaded ring, and the humidity measuring device is arranged in a circular array with the "human"-shaped sealing ring as the center, a mounting hole is provided on the bottom surface of the smart dial, and a first annular sealing ring is provided on the bottom surface of the smart dial.

[0006] Preferably, the humidity measuring device includes a humidity sensor, which is electrically connected to a control unit through wires, and is used to monitor the humidity changes around the "human" shaped sealing ring in real time, the control unit is electrically connected to an alarm unit through wires, the alarm unit is electrically connected to an alarm through wires, the control unit is electrically connected to a display unit through wires, the controller is electrically connected to a SIM card through wires, the controller is electrically connected to a power module through wires, the controller is electrically connected to a wifi module through wires, the controller is electrically connected to a NB communication module through wires, and the NB communication module is electrically connected to a NB antenna through wires.

[0007] Preferably, a fixing plate is fixedly connected to the bottom surface of the smart dial, and there are four fixing plates in a circular array with the "human" shaped sealing ring as the center.

[0008] Preferably, a NB antenna is fixedly connected to the top surface of the smart watch dial, an upper cover is provided on the top surface of the smart watch dial, the upper cover is rotatably connected to the outer wall of the smart watch dial through a hinge, and a handle is fixedly connected to the top surface of the upper cover.

[0010] Preferably, a guide plate is fixedly connected to the inner wall of the input pipe, and the guide plate is arranged at an inclined angle.

[0011] Preferably, a rotating groove is fixedly connected to the bottom of the rotating chamber, one end of a rotating shaft is rotatably connected inside the rotating groove, a fan blade is provided on the outer wall of the rotating shaft, and a gear is fixedly connected to the other end of the rotating shaft, and a second annular sealing ring is provided at the lower part of the gear.

[0012] Preferably, a connecting rod is provided at the lower portion of the second annular sealing ring, and a hammer is fixedly connected to the end of the connecting rod.

[0013] Preferably, a method for using a NB water meter intelligent membrane block sealing structure comprises the following steps: S1. Connect the second connecting ring to the external water inlet pipe, connect the first connecting ring to the external water pipe, and thread the smart dial to the first threaded ring on the upper part of the rotating chamber through the second threaded ring so that the "human" shaped sealing ring and the "n" shaped sealing ring can fit tightly; S2. The water flows through the input pipe, and the water flow direction is changed by the guide plate, and then the water flows into the rotating chamber, so that the fan blades installed on the outer wall of the shaft rotate inside the rotating groove, and then the gear can rotate inside the mounting hole, so that the water flow information is transmitted to the inside of the smart dial in a rotating manner, and then transmitted to the NB communication module through the control unit. The NB communication module uploads the water flow to the server through the NB antenna for interaction, and finally the water flow will be output from the output pipe; S3.

When water seeps out from between the "human" shaped sealing ring and the "n" shaped sealing ring, the humidity sensor will immediately identify the water vapor and identify it as a water leak, and then transmit the water leak signal to the control unit. The control unit will send an alarm signal to the alarm unit, and the alarm unit will transmit the alarm signal to the alarm, which will sound an alarm.

[0014] The present invention provides a NB water meter intelligent membrane block sealing structure, which has the following beneficial effects: 1. In the present invention, the second threaded ring arranged at the bottom can mesh with the first threaded ring arranged at the top of the rotating chamber, and an "n"-shaped sealing ring is arranged on the inner side of the first threaded ring, and a "human"-shaped sealing ring is arranged on the inner side of the second threaded ring. By twisting, the "n"-shaped sealing ring and the "human"-shaped sealing ring are brought close to and squeezed against each other, thereby achieving better sealing, thereby improving the problem that the existing NB smart water meter has a relatively simple sealing structure and poor waterproof effect, which makes the NB smart water meter easily penetrated by water and causes damage to the instrument.

[0015] 2. In the present invention, a humidity sensor is provided on the outside of the "human" shaped sealing ring, and there are four humidity sensors in a circular array with the center of the "human" shaped sealing ring. The "human" shaped sealing ring is electrically connected to a control unit through wires. The humidity changes around the humidity sensor can be monitored in real time through the "human" shaped sealing ring, and the control unit is electrically connected to an alarm unit through wires, and the alarm unit is electrically connected to an alarm through wires. Therefore, when the humidity sensor detects abnormal humidity, the control unit will cause the alarm to sound an alarm, thereby improving the problem of difficult-to-detect aging and water leakage of the sealing ring.

[0016] 3. The present invention can drive the fan blades to rotate through water flow, thereby causing the rotating shaft to rotate inside the rotating groove, and then the connecting rod can drive the fan blades to rotate so that the hammer rotates inside the rotating groove and continuously strikes the side of the fixing plate to continuously tighten it. Since the connecting rod is made of soft material, it will not hinder the rotation of the fan blades, thereby improving the problem of loose threads causing loose sealing.
