Description

Technical Field

[0001] The invention belongs to the technical field of non-magnetic water meters, and in particular relates to an electromechanical separation non-magnetic remote transmission water meter. Background Art

[0002] The structure of non-magnetic water meter is similar to that of pulse meter, but the realization of measurement method is quite different. Pulse meter uses sensor to monitor the rotating pulse of water meter rotor, so it generally needs a magnetic element. Magnetic element is more susceptible to external interference, resulting in inaccurate or no measurement. Non-magnetic water meter is designed to avoid interference of magnetic field.

[0003] The working principle of the non-magnetic water meter is to use a non-contact inductive electronic sensor and non-magnetic signal detection technology to directly read the flow meter impeller rotation circle signal and make flow corrections to the speed, which greatly improves the accuracy and resolution of flow detection. In addition, its low power consumption detection characteristics make it very suitable for household water meters with small flow and frequent switching. The signal detection and counting unit of the non-magnetic water meter adopts purely electronic means, which can make corrections and compensations in the range of large uncertainty such as small flow, and has functions such as forward and reverse identification and data remote communication, making the non-magnetic water meter information-based and intelligent. At present, the non-magnetic water flow on the market usually adopts electromechanical separation, but this method will cause the impeller to have a small position offset or even tilt under the condition of high water pressure and fast water flow, thus affecting the water flow collection.

[0006] The present invention further states that the diameter of the gear is three times the diameter of the toothed disc, and the thickness of both gears is five millimeters.

[0007] The present invention further illustrates that the two gears are respectively meshed with the upper and lower sides of the toothed disk, the sensing modules inside the two electronic sensors are electrically connected, and the sensing modules each include a priority unit, and the priority unit is used to identify the water flow rates sensed by the two sensing modules, and identify the priority based on the water flow data, and transmit the priority data out, specifically in the following manner: when Q1≥Q2, Q1 is the water flow data sensed by the sensing module inside the upper electronic sensor, and Q2 is the water flow data sensed by the sensing module inside the lower electronic sensor, and the priority unit transmits the Q1 data to the signal transmission module; when Q2≥Q1, the priority unit transmits the Q2 data to the signal transmission module.

[0008] The present invention further illustrates that an electric motor is fixedly installed in the middle of the right side of the signal transmission board, and the electric motor is electrically connected to the two sensing modules, a threaded rod is fixedly connected to the output end of the electric motor, and a threaded sleeve is threadedly connected to the right side of the threaded rod; an expansion joint is fixedly connected to the upper end of the threaded sleeve, and the expansion joint is fixed to the right side of the signal transmission board, a calibration block is fixed to the right end of the threaded sleeve, a calibration hole is opened on the right side of the calibration block, and the edge of the calibration hole is arc-shaped, a calibration rod is fixedly installed on the left end of the rotating shaft, and the left end of the calibration rod is arc-shaped, and the diameter of the calibration rod is the same as the inner diameter of the calibration hole.

[0013] The diameter of the gear is three times the diameter of the toothed disc, which can reduce the speed of the gear when the toothed disc rotates at high speed, so that the electronic sensor can fully and timely collect the position of the induction coil, avoiding inaccurate water flow data collection due to excessive speed, and slowing down the induction coil when the electronic sensor collects the number of rotations of the induction coil. When the water pressure is high, the water flow is fast, and the impeller speed increases. At this time, the shaft generates centrifugal force, which drives the impeller to move or tilt slightly. The shaft also tilts or moves, and the position of the toothed disc is offset, which may cause disengagement from one of the gears, or the meshing strength is not high, resulting in inconsistent data collected by the two electronic sensors. At this time, the higher data collected is preferentially transmitted to the signal transmission module, so that the water flow data received by the terminal is more accurate and the water flow collection accuracy is further improved.

DETAILED DESCRIPTION

[0023] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-7 The present invention provides a technical solution: an electromechanical separation non-magnetic remote transmission water meter, including a non-magnetic water meter, a signal transmission board 1, an electromechanical separation mechanism and a remote transmission system, the non-magnetic water meter includes a chamber 2, an impeller 3, a rotating shaft 4, and a gear plate 5, the electromechanical separation mechanism includes a separation chamber 6, two transmission parts, the two transmission parts are relatively arranged on the upper and lower sides of the rotating shaft 4, and both include an electronic sensor 7, a rotating rod 8, and a gear 9;

[0025] A signal transmission instrument 111 is fixedly installed on one side of the signal transmission board 1, and an electronic sensor 7 is fixedly installed on the other side of the signal transmission board 1. The signal transmission board 1 is fixedly installed on the inner wall of the separation chamber 6, and the separation chamber 6 is fixedly installed on the left side of the chamber 2. The impeller 3 bearing is installed inside the chamber 2, and a through hole is provided on the left side of the chamber 2. The rotating shaft 4 is fixedly installed on the left side of the impeller 3 and passes through the through hole. The toothed disc 5 is fixedly installed on the outside of the rotating shaft 4. The rotating rod 8 bearing is installed on the inner wall of the separation chamber 6. The gear 9 is fixedly installed on the outside of the rotating rod 8 and meshes with the toothed disc 5. An induction coil 81 is fixed on the left end of the rotating rod 8. A hole is provided on the right side of the electronic sensor 7, and the induction coil 81 is located in the middle of the hole.

[0026] The remote transmission system includes a signal transmission module and a sensing module. The signal transmission module is arranged inside the signal transmission instrument 111 and is electrically connected to the sensing module. The sensing module is arranged inside the electronic sensor 7. The sensing module is used to sense the induction coil 81, thereby determining the number of rotations of the induction coil 81, and calculating the flow size according to the number of rotations. The signal transmission module is used to transmit the flow size data to the terminal through the signal transmission instrument 111;

[0027] After the water flows into the chamber 2 of the non-magnetic water meter, the impeller 3 is driven to rotate. The impeller 3 drives the toothed disc 5 to rotate through the rotating shaft 4. The toothed disc 5 drives the upper and lower gears 9 to rotate through meshing. The two gears 9 respectively drive the two rotating rods 8 to rotate. The rotating rod 8 drives the induction coil 81 to rotate. The electronic sensor 7 determines the number of rotations of the induction coil 81 through its internal sensing module, calculates the water flow rate according to the number of rotations, and transmits the water flow data to the terminal in real time through the signal transmission module of the signal transmitter 111. The whole process is automated and intelligent. The non-contact inductive electronic sensor 7 is used. The non-magnetic signal detection technology is applied to directly read the number of rotations of the impeller 3 and perform flow correction on the rotation speed, which greatly improves the accuracy and resolution of flow detection. In addition, its low power consumption detection feature is very suitable for household water meters with small flow and frequent switching. The meshing of the toothed disc 5 and the gear 9 can relatively maintain the stability of the toothed disc 5 to prevent the toothed disc 5 from being offset by the centrifugal force due to the high-speed rotation of the impeller 3, thereby affecting the data acquisition accuracy.

[0028] The diameter of the gear 9 is three times the diameter of the toothed disc 5, and the thickness is five millimeters;

[0029] The diameter of the gear 9 is three times the diameter of the toothed disc 5, which can reduce the rotation speed of the gear 9 when the toothed disc 5 rotates at high speed, so that the electronic sensor 7 can fully and timely collect the position of the induction coil 81, avoiding inaccurate water flow data collection due to excessive rotation speed, and slowing down the induction coil 81 when the electronic sensor 7 collects the number of rotations of the induction coil 81.

[0030] The two gears 9 are respectively meshed with the upper and lower sides of the toothed disc 5. The sensing modules inside the two electronic sensors 7 are electrically connected, and the sensing modules both include a priority unit, which is used to identify the water flow rates sensed by the two sensing modules, identify the priority according to the water flow data, and transmit the priority data. The specific method is as follows:

[0031] When Q1≥Q2, Q1 is the water flow data sensed by the sensing module inside the upper electronic sensor 7, and Q2 is the water flow data sensed by the sensing module inside the lower electronic sensor 7, and the priority unit transmits the Q1 data to the signal transmission module;

[0032] When Q2≥Q1, the priority unit transmits Q2 data to the signal transmission module;

[0033] When the water pressure is high, the water flows fast, and the impeller 3 rotates faster. At this time, the rotating shaft 4 generates centrifugal force, thereby driving the impeller 3 to slightly displace or tilt. The rotating shaft 4 also tilts or displaces, and the position of the toothed disc 5 is offset, which may cause it to be out of mesh with one of the gears 9, or the meshing strength is not high, resulting in inconsistent data collected by the two electronic sensors 7. At this time, the higher collected data is preferentially transmitted to the signal transmission module, so that the water flow data received by the terminal is more accurate, and the water flow collection accuracy is further improved.

[0034] An electric motor 112 is fixedly installed in the middle of the right side of the signal transmission board 1, and the electric motor 112 is electrically connected to the two induction modules. A threaded rod 113 is fixedly connected to the output end of the electric motor 112, and a threaded sleeve 114 is threadedly connected to the right side of the threaded rod 113.

[0035] The upper end of the threaded sleeve 114 is fixedly connected with a telescopic joint 115, and the telescopic joint 115 is fixed to the right side of the signal transmission board 1. The right end of the threaded sleeve 114 is fixed with a calibration block 116, and the right side of the calibration block 116 is provided with a calibration hole 117, and the edge of the calibration hole 117 is in an arc shape. The left end of the rotating shaft 4 is fixedly installed with a calibration rod 41, and the left end of the calibration rod 41 is in an arc shape, and the diameter of the calibration rod 41 is the same as the inner diameter of the calibration hole 117;

[0036] Through the above steps, when the water flow data collected by the sensing module is inconsistent, the electric motor 112 is driven to operate through the signal, the electric motor 112 first rotates clockwise, driving the threaded rod 113 to rotate spirally through the threaded sleeve 114, and reversely drives the threaded sleeve 114 to move to the right through the telescopic joint 115, the telescopic joint 115 is extended, and the threaded sleeve 114 drives the calibration block 116 to move to the right, so that the calibration rod 41 of the rotating shaft 4 is inserted into the calibration hole 117 of the calibration block 116, so as to calibrate the center of the rotating shaft 4, and reset the toothed disc 5 and the impeller 3 from the position offset or tilted state to the central horizontal position, which can make the water flow collection data accurate on the one hand, and make the toothed disc 5 and the two gears 9 fully meshed again on the other hand, and the water flow data collection accuracy is further greatly improved. After calibration, the electric motor 112 rotates counterclockwise and resets, so that the rotating shaft 4 is separated from the calibration hole 117 again, avoiding continuous influence on the rotation of the rotating shaft 4, so that the water flow collection work can proceed smoothly.

[0037] The operation steps of the remote transmission system include:

[0038] Step S1, water flows into the chamber 2, and the impeller 3 rotates;

[0039] Step S2, the sensing module of the electronic sensor 7 senses the sensing coil 81, thereby determining the number of rotations of the sensing coil 81, and calculating the flow rate according to the number of rotations;

[0040] Step S3, the priority unit is used to identify the water flow rates sensed by the two sensing modules, identify the priority according to the water flow data, and transmit the priority data. The specific method is as follows: when Q1≥Q2, the priority unit transmits Q1 data to the signal transmission module; when Q2≥Q1, the priority unit transmits Q2 data to the signal transmission module; when Q2=Q1, the process proceeds to step S4; otherwise, the process proceeds to step S5;

[0041] Step S4, the electric motor 112 is operated to calibrate the positions of the toothed disc 5 and the impeller 3, and then the process proceeds to step S5;

[0042] Step S5: The signal transmission module transmits the flow rate data to the terminal via the signal transmission device 111, and collects the data of the non-magnetic water meter in real time.

[0043] In step S3, judging whether there is a data difference through the data between the two sensing modules, thereby selecting the higher data transmission;

[0044] The collected data from non-magnetic water meters are more accurate.

[0045] In step S4, when Q2=Q1, the electric motor 112 does not operate, and when Q2≠Q1, the electric motor 112 operates and rotates clockwise to the limit position and then resets counterclockwise;

[0046] The position of the rotating shaft 4 is calibrated, thereby calibrating the position of the toothed disc 5 and the impeller 3, so as to prevent the impeller 3 from being offset or tilted by the impact of the water flow, which affects the data collection accuracy of the water flow.
