Description

Technical Field

[0001] The invention relates to the technical field of intelligent water meters, in particular to a self-cleaning wireless remote intelligent tele-transmission water meter and a working method thereof. Background Art

[0002] A water meter is an instrument that measures water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. When selecting the specifications of a water meter, you should first estimate the size and range of the flow rate usually used, and then choose the water meter with the specification that is closest to the commonly used flow rate as the first choice;

[0003] However, when there is no water flow through the water meter for a long time, the water accumulated in the water meter will easily cause bacteria to grow on the inner wall of the water meter, and the insoluble impurities in the water will be deposited at the bottom of the water meter. When the water meter is used again, simply flushing it with water cannot completely remove the impurities and bacteria growing on the inner wall of the water meter. The bacteria and impurities on the inner wall of the water meter will pollute the water quality and affect people's use. Therefore, it does not meet the existing needs. We propose a self-cleaning wireless remote intelligent telemeter and its working method. Summary of the invention

[0004] The purpose of the present invention is to provide a self-cleaning wireless remote intelligent water meter and its working method, so as to solve the problem proposed in the above background technology that when there is no water flow through the water meter for a long time, the water accumulated in the water meter is easy to cause bacteria to grow on the inner wall of the water meter, and the insoluble impurities in the water will be deposited at the bottom of the water meter.

[0009] Furthermore, a display screen is embedded in one side of the top inner wall of the upper mounting shell, and the display screen is fixedly connected to the upper mounting shell by bolts, and the display screen is located on one side of the wireless transmission mechanism, and the information processing mechanism is located on one side of the wireless transmission mechanism, and the speed sensor is located on one side of the information processing mechanism, and the guide turntable is located on one side of the sensing end of the speed sensor.

[0010] Furthermore, an observation window is provided on a side of the upper end of the upper mounting shell away from the display screen, and a dust cover is hinged on one side of the observation window, and the instrument panel and the character wheel are both located between the partition and the observation window.

[0011] Furthermore, a No. 2 rotating rod is fixed to the upper end of the No. 1 rotating rod, and a driving gear is fixedly connected to the upper end of the No. 2 rotating rod through a keyway, and the driving gear is connected to the speed change gear set through tooth meshing, and the speed change gear set is located below the partition.

[0012] Furthermore, a limiting block is provided on one side of the driving gear away from the speed change gear set, and the limiting block matches the driving gear, and an extension rod is fixed on the other side of the limiting block, and the other end of the extension rod is fixedly connected to the output end of the electric telescopic rod.

[0014] Furthermore, a water inlet pipe is connected through one side of the water meter body, and a water outlet pipe is connected through the other side of the water meter body, and the water inlet pipe, the water outlet pipe and the impeller are on the same straight line.

[0015] A working method of a self-cleaning wireless remote intelligent water meter comprises the following steps:

[0016] Step 1: Connect the external water pipe to the water inlet pipe and the water outlet pipe in sequence to ensure that the water flows from the water inlet pipe to the water outlet pipe, check the status of each component, keep the battery fully charged, and the electric telescopic rod in a retracted state;

[0017] Step 2: When water flows into the water meter body, the water flow continuously drives the impeller to rotate, and the rotating impeller drives the No. 1 rotating rod, the No. 2 rotating rod and the driving gear to rotate. The driving gear drives the speed gear set to rotate by mutual meshing with the speed gear set. The speed gear set drives the guide turntable and the instrument panel to rotate at different speeds. The speed gear set drives the numbers on the character wheel to change continuously through transmission. The numbers displayed on the character wheel are the water flow rate flowing through the water meter body;

[0018] Step 3: The powered speed sensor detects the speed of the guide turntable, and then transmits the detected speed to the information processing mechanism in the form of an electrical signal. The information processing mechanism converts the speed of the guide turntable detected by the speed sensor into the water flow passing through the water meter body through calculation, and displays the calculated water flow on the display screen;

[0019] Step 4: The wireless transmission mechanism stores the water flow through the water meter calculated by the information processing mechanism, and remotely uploads the recorded water flow to the cloud server in the form of an electrical signal, and then performs networking operations;

[0020] Step 5: When the water in the water meter body is stationary, the impeller and the guide turntable are stationary, and the speed sensor cannot sense the rotation of the guide turntable. When the information processing mechanism receives the electrical signal that the speed of the guide turntable detected by the speed sensor is zero for a long time, the information processing mechanism immediately controls the electric telescopic rod to start, and the output end of the electric telescopic rod drives the extension rod to move toward the direction close to the driving gear, and the extension rod drives the limit block to move until the limit block and the driving gear are engaged with each other;

[0021] Step six: After the limiting block and the driving gear engage with each other, the information processing mechanism controls the cleaning motor to start, and the output end of the cleaning motor drives the driving rod and the connecting disk to rotate, and the connecting disk drives the swing paddle and the cleaning brush to rotate. The swing paddle drives the water in the water meter body to shake and exchange with the water in the external pipe. The cleaning brush cleans impurities, bacteria and other substances attached to the inner wall of the water meter body.

[0022] Compared with the prior art, the present invention has the following beneficial effects: the cleaning motor can drive the connection plate and the swing paddle to rotate, the rotating swing paddle can drive the water in the water meter body to shake, and exchange with the water in the external pipe, so as to keep the water in the water meter body as flowing water, avoid the precipitation of impurities on the inner wall of the water meter body, and reduce the growth of bacteria in a closed environment; the cleaning brush can be driven by the swing paddle to wash and clean the inner wall of the water meter body, so as to keep the inner wall of the water meter body smooth, reduce the attachment of impurities, and ensure the hygiene of water use;

[0023] The wireless transmission mechanism is used to upload the signal transmitted by the information processing mechanism to the cloud server through the Internet of Things to realize the wireless networking function. The information processing mechanism is used to receive and transmit signals and instructions. The speed change gear set can be used for transmission, so that the impeller rotates to drive the instrument panel and the guide turntable to rotate, and the degree of the character wheel is changed through transmission. The character wheel can display the water flow through the water meter body through mechanical transmission, ensuring that the device can normally record the water flow without power. The guide turntable, speed sensor, information processing mechanism and display screen cooperate with each other, and the water flow through the water meter body can be displayed through the display screen, making the water flow degree more intuitive;

[0024] The electric telescopic rod can be started before the cleaning motor is started. The electric telescopic rod is used to push the limiting block to engage with the driving gear to limit the driving gear, thereby avoiding the rotation of the impeller when the swing paddle rotates, thereby improving the monitoring accuracy of the device.

[0043] A working method of a self-cleaning wireless remote intelligent water meter comprises the following steps:

[0044] Step 1: Connect the external water pipe to the water inlet pipe 33 and the water outlet pipe 34 in sequence to ensure that water flows from the water inlet pipe 33 to the water outlet pipe 34, check the status of each component, keep the battery 20 fully charged, and keep the electric telescopic rod 24 in a retracted state;

[0045] Step 2: When water flows into the water meter body 1, the water flow continuously drives the impeller 11 to rotate, and the rotating impeller 11 drives the No. 1 rotating rod 10, the No. 2 rotating rod 21 and the driving gear 22 to rotate.

6. A method for operating a self-cleaning wireless remote intelligent water meter, based on the self-cleaning wireless remote intelligent water meter of claim 5, characterized in that: The steps include: Step 1: connect the external water pipe to the water inlet pipe (33) and the water outlet pipe (34) in sequence to ensure that water flows from the water inlet pipe (33) to the water outlet pipe (34), check the status of each component, keep the battery (20) fully charged, and keep the electric telescopic rod (24) in a retracted state; Step 2: When water flows into the water meter body (1), the water flow continuously drives the impeller (11) to rotate. The rotating impeller (11) drives the first rotating rod (10), the second rotating rod (21) and the driving gear (22) to rotate. The driving gear (22) drives the speed change gear set (23) to rotate by mutual meshing with the speed change gear set (23). The speed change gear set (23) drives the guide rotating disk (28) and the instrument panel (27) to rotate at different speeds. The speed change gear set (23) drives the numbers on the character wheel (32) to continuously change through transmission. The numbers displayed on the character wheel (32) are the water flow rate flowing through the water meter body (1); Step 3: The energized speed sensor (29) detects the speed of the guide rotating disk (28), and then transmits the detected speed to the information processing unit (5) in the form of an electrical signal. The information processing unit (5) converts the speed of the guide rotating disk (28) detected by the speed sensor (29) into the water flow passing through the water meter body (1) through calculation, and displays the calculated water flow on the display screen (6); Step 4: The wireless transmission mechanism (4) stores the water flow through the water meter body (1) calculated by the information processing mechanism (5), and remotely uploads the recorded water flow in the form of an electrical signal to a cloud server, and then performs networking operations; Step 5: When the water in the water meter body (1) is stationary, the impeller (11) and the guide turntable (28) are stationary, and the speed sensor (29) cannot sense the rotation of the guide turntable (28). When the information processing mechanism (5) receives an electrical signal indicating that the speed of the guide turntable (28) is zero as detected by the speed sensor (29) for a long time, the information processing mechanism (5) immediately controls the electric telescopic rod (24) to start, and the output end of the electric telescopic rod (24) drives the extension rod (25) to move in a direction close to the driving gear (22), and the extension rod (25) drives the limiting block (26) to move until the limiting block (26) and the driving gear (22) are engaged with each other; Step 6: After the limiting block (26) and the driving gear (22) are engaged with each other, the information processing mechanism (5) controls the cleaning motor (15) to start, and the output end of the cleaning motor (15) drives the driving rotating rod (16) and the connecting plate (17) to rotate, and the connecting plate (17) drives the swinging paddle (18) and the cleaning brush (19) to rotate. The swinging paddle (18) drives the water in the water meter body (1) to shake and exchange with the water in the external pipe, and the cleaning brush (19) cleans the impurities and bacteria attached to the inner wall of the water meter body (1).
