Description

Technical Field

[0001] The invention belongs to the technical field of water meters, and in particular relates to a wireless intelligent remote transmission water meter. Background Art

[0002] A water meter is a metering instrument used to measure the amount of water flowing in a pipe. In order to measure the water consumption of tap water users, a water meter must be installed at the entrance of each tap water user. In the urban tap water network system, there are quite a large number of water meters. In order to manage the tap water system, the water meter data of tap water users must be copied. At present, the water meter with a large amount of use in the tap water network system is a mechanical water meter with on-site indication. The mechanical water meter has a shell, and the two ends of the shell have a water inlet and a water outlet respectively. There is an impeller measuring mechanism between the water inlet and the water outlet in the shell. The impeller measuring mechanism is connected to a speed reduction mechanism and an indicator. The mechanical water meter needs to be used on-site and indicates data on-site. When copying the water meter data, a large number of meter readers are required to go to the site to manually copy the water meter data. The work of meter reading is quite huge and complicated, the copying work is inefficient, and the copying link is prone to errors. In order to improve the efficiency of the meter reading work, in the prior art, remote water meters are used to replace mechanical water meters with local indication. The remote water meters include pulse remote water meters. The pulse remote water meters are in which the impeller measuring mechanism in the shell of the above-mentioned mechanical water meter is connected to a pulse sensor. The pulse sensor outputs a pulse signal according to the number of impeller revolutions, converts the mechanical water meter data into a pulse signal, and uses the number of pulse signals to represent the amount of water. The pulse signal of the water meter data is transmitted remotely by wires to realize remote meter reading. However, when the impeller revolutions are collected by the pulse sensor, when the impeller speed is high, the collected revolution data will be inaccurate and missed collection will occur.

[0007] The present invention further illustrates that a magnetic block is fixedly installed on one side of the upper part of the disk, a magnetic ball is fixedly installed on the inner wall of the chamber, the magnetic ball is located on one side of the magnetic block, and the magnetic poles of the magnetic ball and the magnetic block are opposite; a limiting block one is fixed on the outer side of the bottom of the round rod, and a limiting block two is fixedly installed on the upper surface of the connecting block below, the limiting block one and the limiting block two are in contact with each other, and the limiting block two is located on the outer side of the limiting block one.

[0008] The present invention further illustrates that the operation method of the wireless intelligent remote water meter includes the following steps: step S1, water flows into the shell through the water inlet pipe and is then discharged through the water outlet pipe.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention adopts the method of judging the number of revolutions of the impeller, and then the flow calculation module calculates the water flow size according to the number of revolutions of the impeller, and transmits the real-time data of the water flow size to the terminal through the wireless transmission module, so that no one manually collects the water meter value, which is convenient and efficient, and the data accuracy is high;

[0013] For slow water flows, it can not only ensure the collection of water flow data, but also prevent the collision between the contact ball and the sphere from causing the impeller to freeze, thereby avoiding affecting the accuracy of the water flow data.

DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-8 The present invention provides a technical solution: a wireless intelligent remote water meter, comprising a housing 1 and a wireless intelligent remote transmission system, wherein the left side of the housing 1 is connected to a water inlet pipe 2, and the right side is connected to a water outlet pipe 3; a flow conduction mechanism is installed in the middle of the housing 1, and the flow conduction mechanism comprises an impeller 4, a chamber 5, a sensor 6, a fixed panel 7 and a wireless transmitter 8;

[0026] The impeller 4 is arranged in the middle of the housing 1, and a rotating rod 41 is fixedly installed on the upper end. The chamber 5 is fixedly installed inside the housing 1. The sensor 6 is fixedly installed in the middle of the chamber 5. The fixed panel 7 is fixedly installed above the chamber 5. The wireless transmitter 8 is fixedly installed on the upper right side of the chamber 5. The upper end of the rotating rod 41 is provided with a sensing layer 42 on the outer side, and the upper end is inserted into the sensor 6.

[0027] The wireless intelligent remote transmission system includes a sensing module, a flow calculation module, and a wireless transmission module. The sensing module is arranged inside the sensor 6 and is electrically connected to the flow calculation module. The wireless transmission module is arranged inside the wireless transmitter 8 and is electrically connected to the flow calculation module. The sensing module is used to determine the rotation of the impeller 4 by identifying the position of the sensing layer 42 and recording the number of rotations. The flow calculation module is used to calculate the water flow size according to the number of rotations of the impeller 4. The wireless transmission module is used to transmit the calculated water flow size through a signal and transmit it to the terminal.

[0028] Water flows into the shell 1 through the water inlet pipe 2 and is then discharged through the water outlet pipe 3. When the water flows through the shell 1, the impeller 4 is driven to rotate, and the impeller 4 drives the rotating rod 41 to rotate. The sensing layer 42 at the upper end of the rotating rod 41 rotates, and the position of the sensing layer 42 is identified by the sensor 6. When the sensing layer 42 rotates one circle through the rotating rod 41, the sensor 6 senses it and records the rotation of the sensing layer 42 through the sensing module. The number of rotations of the sensing layer 42 is recorded in real time, thereby judging the number of rotations of the impeller 4. After that, the flow calculation module calculates the water flow rate according to the number of rotations of the impeller 4, and transmits the real-time data of the water flow rate to the terminal through the wireless transmission module. The water meter value is collected manually without human intervention, which is convenient and efficient, and the data accuracy is high.

[0029] A gear 43 is fixedly mounted on the outer side of the rotating rod 41. The interior of the chamber 5 is hollow, and a pin 44 is connected to the inner wall axis. A toothed disc 45 is fixedly mounted on the outer side of the pin 44.

[0030] A track 441 is fixedly installed on one side of the bottom of the pin 44, a slider 442 is slidably connected to the inner wall of the track 441, and a spring is fixed between the slider 442 and the inner side of the track 441, an inertia rod 443 is fixedly installed on the outer side of the slider 442, a connecting rod 444 is connected to the outer end of the inertia rod 443, a contact ball 445 is fixedly installed on the outer end of the connecting rod 444, a vibration sensor 51 is fixed on the upper part of the inner wall of the chamber 5, a ball 52 is connected to the lower end of the vibration sensor 51, and the ball 52 and the contact ball 445 are aligned with each other;

[0031] The vibration sensor 51 is internally provided with a vibration sensing module and a times calculation module, the vibration sensing module is electrically connected to the times calculation module, the times calculation module is electrically connected to the flow calculation module, the vibration sensing module is used to sense the vibration generated by the contact ball 445 hitting the ball 52, the times calculation module is used to record the vibration times, and the flow calculation module is also used to calculate the water flow according to the vibration times;

[0032] When the speed of the impeller 4 increases, an error occurs when the sensor 6 collects the number of rotations of the sensing layer 42. The rotation of the impeller 4 drives the gear 43 to rotate through the rotating rod 41. The gear 43 drives the toothed disc 45 to rotate through meshing. The toothed disc 45 drives the pin 44 to rotate. The pin 44 drives the track 441 to rotate around its center. The slider 442 inside it slides outward along the track 441 under the action of inertia. The spring is deformed by force. At the same time, the slider 442 drives the inertial rod 443 to move outward, thereby driving the contact ball 445 to move outward through the connecting rod 444 until it can hit the sphere 52. When the contact ball 445 hits the sphere 52, vibration is generated. The number of vibrations is collected by the vibration sensing module, and the water flow rate is calculated based on the number of vibrations. This data collection method has relatively higher accuracy and is operated under conditions of faster water flow, which can maximize the accuracy of water flow data.

[0033] A fixed block is fixedly installed on the right side of the inertia rod 443, and connecting blocks 447 are fixedly installed on the upper and lower sides of the outer side of the fixed block. A round rod 448 is axially connected between the two connecting blocks 447, and a disc 449 is fixedly installed on one side of the upper surface of the round rod 448;

[0034] When the connecting rod 444 drives the contact ball 445 to move outward and collide with the sphere 52, the connecting rod 444 is subjected to force and rotates on the connecting block 447 through the round rod 448, thereby driving the disc 449 to rotate, avoiding affecting the accuracy of the water flow data. When the contact ball 445 hits the sphere 52, no excessive reaction force is generated. This method can avoid the contact ball 445 from having a hard impact when colliding with the sphere 52, thereby affecting the rotation of the impeller 4, while being able to generate vibration at the same time.

[0035] A magnetic block 446 is fixedly mounted on one side of the upper side of the disk 449, and a magnetic ball 53 is fixedly mounted on the inner wall of the chamber 5. The magnetic ball 53 is located on one side of the magnetic block 446, and the magnetic poles of the magnetic ball 53 and the magnetic block 446 are opposite;

[0036] A limit block 1 46 is fixed to the outer side of the bottom of the round rod 448, and a limit block 2 47 is fixed to the upper surface of the lower connecting block 447. The limit block 1 46 and the limit block 2 47 fit each other, and the limit block 2 47 is located on the outer side of the limit block 1 46;

[0037] When the disk 449 rotates, the magnetic block 446 is driven to rotate around the center of the disk 449. Then, when the disk 449 approaches the magnetic ball 53, the magnetic attraction generated by the magnetic ball 53 and the magnetic block 446 pulls the disk 449 to reset through the magnetic block 446, and the contact ball 445 has passed the sphere 52.

[0038] By means of limit block 1 46 and limit block 2 47, the round rod 448 can be rotated in a small range and reset smoothly, so that each vibration can be successfully collected. The track 441 is not directly installed on the rotating rod 41, but a pin shaft 44 and a gear plate 45 are additionally added, so that the stability of the impeller 4 remains unchanged when rotating, avoiding the impeller 4 from being broken in its balance force and affecting the calculated data of the water flow, thereby improving stability.

[0039] The operation method of the wireless intelligent remote water meter includes the following steps:

[0040] Step S1, water flows into the housing 1 through the water inlet pipe 2, and then is discharged through the water outlet pipe 3. The water flow drives the impeller 4 to rotate, and the impeller 4 causes the rotating rod 41 to rotate;

[0041] Step S2, the rotating rod 41 rotates, and the impeller 4 rotates by identifying the position of the sensing layer 42, and the number of rotations is recorded. The flow calculation module calculates the water flow according to the number of rotations of the impeller 4. When the water flow speed is fast and the impeller 4 rotates fast, the process proceeds to step S3, otherwise it proceeds to step S4;

[0042] Step S3, the vibration generated by the contact ball 445 hitting the sphere 52 is sensed by the vibration sensing module, and the vibration times are recorded by the times calculation module, and the flow calculation module calculates the water flow according to the vibration times;

[0043] Step S4: Finally, the calculated water flow rate is transmitted via a signal through the wireless transmission module and transmitted to the terminal.

[0044] In step S2, when V min <V<V mid When V min V is the slowest water flow velocity in the water meter, mid is the normal water flow velocity in the water meter, and V is the real-time water flow velocity in the water meter: At this time, the water flow rate is identified by judging the number of revolutions of the impeller 4;

[0045] In this way, the rotation speed of the rotating rod 41 is slow, and the speed at which the sensing layer 42 rotates around the rotating rod 41 is slow, so that the sensor 6 can smoothly collect the number of rotations of the sensing layer 42. This is for the case where the water flow speed is not fast. It can not only ensure the collection of water flow data, but also prevent the collision between the contact ball 445 and the sphere 52 from causing the impeller 4 to rotate jammed, thereby avoiding affecting the accuracy of the water flow data.

[0046] In step S3, when V mid ≤V≤V max When V max The fastest water flow rate in the water meter: At this time, the water flow rate is identified by counting the number of vibrations;

[0047] When the water flow speed is fast, the sensor 6 can no longer accurately collect the number of rotations of the sensing layer 42, and thus judge the water flow rate by the impact vibration between the contact ball 445 and the sphere 52. When the impeller 4 rotates at a high speed, the vibration caused by the impact between the contact ball 445 and the sphere 52 will not affect the rotation of the impeller 4, thereby ensuring the accuracy of the water flow data.

[0048] In step S1 to step S4, the method of calculating the water flow rate changes with the speed of the impeller 4, thereby automatically switching;

[0049] If the water flow rate is slow, the water flow calculation method of step S2 is used, and if the water flow rate is fast, the water flow calculation method of step S3 is used. In this way, the water flow data received by the operator at the terminal is highly accurate and will not have any errors.
