Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) smart water meter technology, and more particularly to an IoT smart water meter. Background Technology

[0002] A water meter is an instrument that measures the flow of water. Most of them measure the cumulative flow of water. They are generally divided into two categories: volumetric water meters and velocity water meters. Originating in Britain, water meters have a history of nearly two hundred years.

[0003] IoT smart water meters are a type of water meter. Compared with traditional water meters, IoT smart water meters have many advantages, including: real-time monitoring and data collection, remote meter reading and billing.

[0004] During the use of IoT smart water meters, due to their high monitoring accuracy, when heavy rain or other conditions increase the amount of impurities in the tap water, including fine sand and fibrous materials, even though the IoT smart water meter has excellent filtration performance, the filtering of fine sand and fibrous materials may still cause blockages inside the meter, thus affecting the monitoring accuracy. Summary of the Invention

[0005] This invention discloses an Internet of Things (IoT) smart water meter, which aims to solve the technical problem that filtering fine sand and fibrous materials may cause blockages inside the water meter, thereby affecting the monitoring accuracy of the water meter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An IoT smart water meter includes a water meter body, an auxiliary monitoring mechanism at the top of the water meter body, and a dehumidification mechanism within the auxiliary monitoring mechanism. A water outlet and a water inlet are connected to both ends of the water meter body, and a filtration mechanism is provided between the water meter body and the water inlet. The filtration mechanism includes a supporting shell, with partitions attached to the inner walls of the front and rear sides of the supporting shell. A second frame is provided between the two partitions, and a second filter screen is fixed within the second frame. Sliding strips are provided at the top and bottom of the second frame. The second frame is slidable by the sliding strips. A first frame is movably connected to the first frame, and the slide bar is movably engaged in the slide groove on the first frame. A first filter screen is fixed inside the first frame. A nut is fixedly connected to the top outer wall of the first frame, and a reciprocating screw is movably engaged inside the nut. The reciprocating screw is set at the top of the second frame through connection with a bearing seat, and a stepper motor is connected to one end of the reciprocating screw. Multiple support bars are fixed at equal density on one side outer wall of the first frame, and multiple needles are fixed on each support bar. Multiple first brushes and blades are fixedly connected to the left and right inner walls of the support housing, respectively.

[0008] The system incorporates a filtration mechanism, with the first filter screen closest to the water inlet. Support bars and needles prevent the entry of fibrous materials, such as aquatic plants, into the water. After a period of use, a remotely controlled stepper motor drives a reciprocating screw, causing the first frame to move back and forth along the screw. When it contacts the blades, it cuts the fibers adhering to the needles. Moving back to the first brush position, it cleans the cut fibers and fine sand adhering to the first filter screen, ensuring the filtration effect of the first filter screen. Additionally, a second filter screen provides temporary filtration during the movement of the first filter screen. This structure prevents fibrous materials and fine sand in the water from entering the water meter and affecting the accuracy of the readings.

[0009] In a preferred embodiment, the bottom end of the support housing is connected to a storage compartment, and the storage compartment is provided with multiple guide plates. A second brush is provided on the side of the first frame opposite to the second filter screen, and the second brush is in contact with the second filter screen.

[0010] With a collection compartment and a second brush, the fine sand and fibrous materials after cleaning can be temporarily stored in the collection compartment through sedimentation. The guidance and shielding of multiple guide plates can prevent debris from moving upward with the water and causing blockage. At the same time, the second brush can clean the surface of the second filter screen simultaneously during the movement of the first frame, ensuring the filtration performance of the second filter screen.

[0011] In a preferred embodiment, the top of the water meter body is simultaneously provided with a fluorescent electronic digital display dial and a fluorescent counting dial. The auxiliary monitoring mechanism includes a sealed housing. The inner wall of the top of the sealed housing is simultaneously provided with a first camera, a second camera, and an ultraviolet lamp. The first camera is located directly above the fluorescent counting dial, the second camera is located directly above the fluorescent electronic digital display dial, and the ultraviolet lamp is located on one side of the fluorescent electronic digital display dial. A second refractive mirror is provided on the inner wall of the sealed housing near the ultraviolet lamp. A refractive lens is provided on the inclined surface of the sealed housing corresponding to one side of the fluorescent electronic digital display dial, and a first refractive mirror is provided on the inner wall of the sealed housing near the first camera.

[0012] By setting up an auxiliary monitoring mechanism, the auxiliary monitoring mechanism can simultaneously monitor the values ​​on the fluorescent technology dial and the fluorescent electronic digital display dial through the first and second cameras. Through remote transmission via the Internet of Things, it can realize the correction of the two counting methods on the water meter and the counting values ​​displayed on the terminal. At the same time, through the fluorescent display method, the light provided by a single ultraviolet lamp is absorbed by the fluorescence and then color is displayed. This method is also more energy-efficient, thereby ensuring the battery life. The guidance of the refracting lens can also ensure the acquisition of water meter values ​​when directly observing the water meter.

[0013] In a preferred embodiment, the dehumidification mechanism includes two mounting bases, which are respectively located on both sides of the inner wall of the top of the sealed housing. Each mounting base is equipped with a fan. Multiple micro-vents are provided on one side of the sealed housing near the bottom. Heat sinks are provided on the opposite outer walls of the sealed housing. A support frame is snapped onto the inner wall of the top of the sealed housing, and a mesh bag is fixed to the bottom of the support frame. The mesh bag is filled with activated carbon particles, and a PES one-way membrane is provided on the inner wall of the top of the mesh bag.

[0014] By incorporating a dehumidification mechanism, which conducts heat to the outside environment through a fan and heat sink, the temperature difference between the inside and outside is reduced. At the same time, activated carbon particles in the mesh bag adsorb internal moisture. Through the dual effects of moisture absorption and temperature control, water vapor generated inside the sealed shell can be avoided from affecting the readings.

[0015] As described above, an IoT smart water meter includes a water meter body. An auxiliary monitoring mechanism is located at the top of the water meter body, and a dehumidification mechanism is located within the auxiliary monitoring mechanism. A water outlet and a water inlet are connected to both ends of the water meter body, respectively, and a filtration mechanism is located between the water meter body and the water inlet. The filtration mechanism includes a supporting shell, with partitions attached to the inner walls of the front and rear sides of the supporting shell. A second frame is located between the two partitions, and a second filter screen is fixed within the second frame. Sliding strips are located at the top and bottom of the second frame. A first frame is movably connected via a sliding strip, which engages with a groove on the first frame. A first filter screen is fixed inside the first frame. A nut is fixedly connected to the top outer wall of the first frame, and a reciprocating screw is movably engaged within the nut. The reciprocating screw is connected to a bearing seat and positioned at the top of a second frame, with one end connected to a stepper motor. Multiple support bars are fixed at equal density on one side outer wall of the first frame, and multiple needles are fixed on each support bar. Multiple first brushes and blades are fixedly connected to the inner walls of the left and right sides of the support housing, respectively. The IoT smart water meter provided by this invention has the technical effect of preventing fibrous materials and fine sand in the water from entering the water meter and affecting the accuracy of the reading.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] The IoT smart water meter disclosed in this invention is mainly applied to scenarios where smart water meters are used.

[0025] Reference Figure 1 and Figure 3-6An IoT smart water meter includes a water meter body 2, an auxiliary monitoring mechanism 3 at the top of the water meter body 2, and a dehumidification mechanism 4 inside the auxiliary monitoring mechanism 3. A water outlet 1 and a water inlet 6 are connected to both ends of the water meter body 2, and a filter mechanism 5 is provided between the water meter body 2 and the water inlet 6. The filter mechanism 5 includes a support housing 513, with partitions 512 attached to the inner walls of the front and rear sides of the support housing 513, and a second frame 507 between the two partitions 512. A second filter screen 508 is fixed inside the second frame 507. The top and bottom ends of the second frame 507 are respectively provided with slide bars 511; the second frame 507 is movably connected to the first frame 505 through the slide bars 511, and the slide bars 511 are movably engaged in the slide grooves 516 on the first frame 505. The first filter screen 506 is fixed inside the first frame 505. The top outer wall of the first frame 505 is fixedly connected with a nut 504, and a reciprocating screw 503 is movably engaged inside the nut 504. The reciprocating screw 503 is set at the top of the second frame 507 through connection with the bearing seat 502, and one end of the reciprocating screw 503 is connected to a stepper motor. Motor 501; Multiple support bars 517 are fixed at equal density on one side outer wall of the first frame 505, and multiple needles 518 are fixed on each support bar 517. Multiple first brushes 510 and blades 509 are fixedly connected to the left and right inner walls of the support housing 513. In the filtration mechanism, the first filter screen 506 is closest to the water inlet. The support bars 517 and needles 518 can block fibrous materials in the water, such as aquatic plants. After a period of use, the stepper motor 501 drives the reciprocating screw 503 to rotate via remote control. The first frame 505 moves back and forth along the reciprocating screw 503. When it contacts the blade 509, it can cut the fibers adhering to the needle 518. When it moves to the first brush 510 position again, it can clean the cut fibers and the fine sand adhering to the first filter screen 506, thereby ensuring the filtration effect of the first filter screen 506. In addition, when the first filter screen 506 moves, the second filter screen 508 can play a temporary filtration role. Under this structure, it can prevent fibrous materials and fine sand contained in the water from entering the water meter and affecting the reading accuracy.

[0026] Reference Figure 5 and Figure 6In a preferred embodiment, a storage compartment 514 is connected to the bottom end of the support housing 513, and multiple guide plates 519 are provided inside the storage compartment 514. A second brush 515 is provided on the side of the first frame 505 opposite to the second filter screen 508, and the second brush 515 is in contact with the second filter screen 508. After cleaning, fine sand and fibrous materials can be temporarily stored in the storage compartment 514 through sedimentation. Through the guidance and blocking of multiple guide plates 519, debris can be prevented from moving upward with the water and causing blockage. At the same time, through the setting of the second brush 515, the surface of the second filter screen 508 can be cleaned simultaneously during the movement of the first frame 505, ensuring the filtration performance of the second filter screen 508.

[0027] Reference Figure 1 and Figure 2 In a preferred embodiment, the top of the water meter body 2 is provided with a fluorescent electronic digital display dial 7 and a fluorescent counting dial 8. The auxiliary monitoring mechanism 3 includes a sealed housing 301, and the inner wall of the top of the sealed housing 301 is provided with a first camera 303, a second camera 305 and an ultraviolet lamp 306.

[0028] Reference Figure 2 In a preferred embodiment, the first camera 303 is located directly above the fluorescent counting dial 8, the second camera 305 is located directly above the fluorescent electronic digital display dial 7, the ultraviolet lamp 306 is located on one side of the fluorescent electronic digital display dial 7, and a second refractor 307 is provided on the inner wall of the sealed housing 301 near the ultraviolet lamp 306.

[0029] Reference Figure 2 In a preferred embodiment, a refractive lens 304 is provided on the inclined surface of the sealed housing 301 corresponding to the fluorescent electronic digital display dial 7, and a first refractive mirror 302 is provided on the inner wall of the sealed housing 301 near the first camera 303. The auxiliary monitoring mechanism 3 can simultaneously monitor the values ​​on the fluorescent technology dial 8 and the fluorescent electronic digital display dial 7 through the first camera 303 and the second camera 305. Through remote transmission via the Internet of Things, it can realize the correction of the two counting methods on the water meter and the counting values ​​displayed on the terminal. At the same time, it can display the values ​​through fluorescent display. The light provided by a single ultraviolet lamp 306 is absorbed by fluorescence and then develops color. Through the refraction of the second refracting mirror 307 and the first refracting mirror 302, the irradiation range of the ultraviolet lamp 306 is increased, so that it can simultaneously absorb light from the fluorescent technology dial 8 and the fluorescent electronic digital display dial 7. The color can be developed for 8 hours after half an hour of absorption. Thus, ordinary cameras can meet the image acquisition requirements. Compared with the method of using ordinary lighting, this method is also more energy-efficient, thereby ensuring the battery life. The guidance of the refracting lens 304 can also ensure the acquisition of water meter values ​​when directly observing the water meter.

[0030] Reference Figure 2 In a preferred embodiment, the dehumidification mechanism 4 includes two mounting bases 403, which are respectively disposed on both sides of the inner wall of the top of the sealed housing 301. Each mounting base 403 is equipped with a fan 404, and a plurality of micro ventilation holes 408 are provided on one side of the sealed housing 301 at a lower position.

[0031] Reference Figure 2 and Figure 3 In a preferred embodiment, heat sinks 401 are respectively provided on the outer walls of the opposite sides of the sealed housing 301, a support 407 is snapped onto the inner wall of the top of the sealed housing 301, and a net bag 402 is fixed at the bottom end of the support 407.

[0032] Reference Figure 3 In a preferred embodiment, the mesh bag 402 is filled with activated carbon particles 406, and a PES one-way membrane 405 is provided on the inner wall of the top of the mesh bag 402. The dehumidification mechanism 4 drives the air inside the sealed housing 301 to flow inside the sealed housing 301 through the fan 404. The flowing air conducts heat with the outside temperature through the heat sink 401, thereby reducing the temperature difference between the inside and outside. At the same time, the activated carbon particles 406 in the mesh bag 402 adsorb the internal moisture. The fan 404 acts on the activated carbon particles 406 while guiding the air, which has a drying effect. The moisture is discharged through the PES one-way membrane, thereby ensuring the service life of the activated carbon particles 406 and preventing the external moisture from being adsorbed by the activated carbon particles 406. Thus, through the dual effects of moisture absorption and constant temperature, the generation of water vapor inside the sealed housing 301 can be avoided from affecting the reading.

[0033] Working principle: In the filtration mechanism, the first filter screen 506 is closest to the water inlet. The support bars 517 and needles 518 can block fibrous materials in the water, such as aquatic plants. After a period of use, the stepper motor 501, controlled remotely, drives the reciprocating screw 503 to rotate, causing the first frame 505 to move back and forth along the screw 503. When it contacts the blade 509, it cuts the fibers adhering to the needles 518. When it moves to the first brush 510, it cleans the cut fibers and fine sand adhering to the first filter screen 506, thus ensuring the filtration effect of the first filter screen 506. Additionally, during the movement of the first filter screen 506, the second filter screen... 508 can serve as a temporary filter. This structure prevents fibrous materials and fine sand in the water from entering the water meter and affecting the accuracy of the readings. After cleaning, the fine sand and fibrous materials can settle and be temporarily stored in the collection chamber 514. Multiple guide plates 519 guide and shield the filter to prevent debris from rising with the water and causing blockages. Simultaneously, the second brush 515 cleans the surface of the second filter 508 while the first frame 505 moves, ensuring the filtration performance of the second filter 508. The auxiliary monitoring mechanism 3 can simultaneously monitor the values ​​on the fluorescent technology dial 8 and the fluorescent electronic digital display dial 7 via the first camera 303 and the second camera 305. Through IoT remote transmission, calibration of the two counting methods on the water meter and the counting values ​​displayed on the terminal can be achieved. Simultaneously, using a fluorescent display method, light from a single ultraviolet lamp 306 is absorbed by fluorescence to produce color. Refraction by the second refracting mirror 307 and the first refracting mirror 302 increases the irradiation range of the ultraviolet lamp 306, allowing it to simultaneously absorb light from both the fluorescent technology dial 8 and the fluorescent electronic digital display dial 7. Half an hour of absorption yields eight hours of color development. Therefore, a standard camera can meet the image acquisition requirements. Compared to using ordinary lighting, this method is more energy-efficient, thus ensuring battery life. The guidance of the refracting lens 304 also ensures accurate water meter readings during direct observation. In addition to obtaining the readings, the dehumidification mechanism 4 uses a fan 404 to drive the air inside the sealed housing 301 to circulate within the housing. The flowing air conducts heat to the outside environment through the heat sink 401, thereby reducing the temperature difference between the inside and outside. At the same time, the activated carbon particles 406 in the mesh bag 402 adsorb the internal moisture. The fan 404 acts on the activated carbon particles 406 while guiding the airflow, achieving a drying effect. The moisture is discharged through the PES one-way membrane, thus ensuring the service life of the activated carbon particles 406 and preventing external moisture from being adsorbed by the activated carbon particles 406. Therefore, through the dual effects of moisture absorption and temperature control, the generation of water vapor inside the sealed housing 301 can be prevented from affecting the readings.
