Description

Technical Field

[0001] This invention relates to the field of water meter technology, and more particularly to the field of smart water meter technology, specifically a smart water meter with water quality monitoring function. Background Technology

[0002] A water meter is a measuring instrument used to measure the volume of water flowing through a pipe. As a core measuring device in a water supply system, it provides accurate data support for water resource management and leakage detection in supply. The working principle of a water meter is usually based on the water flow driving the impeller to rotate, and the counting mechanism is used to accumulate the number of rotations and convert them into a water consumption figure.

[0003] Smart water meters integrate microelectronics, intelligent sensing, and communication technologies into ordinary water meters. Unlike ordinary water meters that rely solely on mechanical transmission via gear sets for metering, smart water meters are equipped with an electronic conversion device that converts impeller rotation into electrical pulse signals. This allows for the digital collection of water consumption and enables intelligent functions such as remote real-time monitoring and remote data collection.

[0004] For example, Chinese patent CN112729445B discloses a water meter and its usage method. The water meter includes a housing, a filter assembly, a rectifier, and an impeller. The housing has a cavity. The filter assembly includes a filter screen and a drive component. The filter screen is disposed in the cavity. Rotating the drive component causes the filter screen to rotate in the cavity. The rectifier is disposed in the cavity and located above the filter screen. The impeller is rotated and disposed in the rectifier cavity of the rectifier.

[0005] Based on the aforementioned patents, existing solutions, and practical usage, current smart water meters still have some problems, such as:

[0006] The metering mechanism of existing smart water meters mainly consists of a rectifier clipped into the water meter housing, a filter cover fitted outside the rectifier, an impeller rotatably connected inside the rectifier, and a counting dial magnetically connected to the impeller. The filter cover is used to filter out and block impurities in the water flow. However, the filter cover in existing smart water meters can only play a single blocking role and cannot effectively collect the filtered impurities. Secondly, the filter cover in existing smart water meters is assembled by fitting it outside the rectifier and inside the water meter housing. That is, the filter cover is assembled together with the rectifier, impeller, and counting dial and other metering mechanism components. When cleaning the filter cover, it is impossible to remove it separately. The entire smart water meter must be completely disassembled, which greatly increases the number of operation steps and affects the convenience of operation.

[0007] The assembly method of the filter screen in the above patent is similar to the assembly method of the filter cover in existing smart water meters. The filter screen in the above patent is set in the cavity of the water meter housing and is placed below the rectifier in a sleeve shape. That is, the filter screen is also assembled together with the rectifier and metering mechanism components such as the impeller. Although the filter screen in the above patent is divided into a first mesh body and a second mesh body, and a storage cavity is defined between the first mesh body and the second mesh body to collect the filtered impurities, the above patent also cannot achieve the separate disassembly of the filter screen when cleaning it.

[0008] In addition, existing smart water meters and the water meters in the aforementioned patents are relatively simple in function, only able to meet the basic needs of water volume measurement, and cannot perform diverse water quality monitoring of the water flowing through the smart water meter, thus failing to ensure water safety.

[0009] Therefore, we propose a smart water meter with water quality monitoring function to solve the problems mentioned above. Summary of the Invention

[0010] The purpose of this invention is to provide a smart water meter with water quality monitoring function, so as to solve the problems mentioned in the background art, such as the inability to perform diverse water quality monitoring on the water flowing through the smart water meter, the inability to effectively collect filtered impurities, and the inability to disassemble the filter components separately, which affects the ease of operation.

[0011] To achieve the above objectives, the present invention provides the following technical solution: a smart water meter with water quality monitoring function, comprising:

[0012] The main cylinder has an integrated water outlet pipe connected to its right side, and an integrated auxiliary cylinder has an integrated auxiliary cylinder on its left side. A connecting pipe cavity is opened between the two, and an integrated water inlet pipe is connected to the left side of the auxiliary cylinder.

[0013] Also includes:

[0014] A filter assembly is installed inside the connecting pipe cavity. The filter assembly filters out and collects impurities in the water flowing through the smart water meter, preventing impurities in the water from interfering with the metering assembly inside the main cylinder. The filter assembly and the metering assembly are separately installed and can be disassembled individually.

[0015] The monitoring components are arranged in a circular array with the center of the sub-cylinder as the center, and the monitoring components are used to perform various water quality monitoring on the water flowing through the smart water meter.

[0016] Preferably, the filter assembly includes a circular filter cartridge and an end cap welded to the circular filter cartridge. The circular filter cartridge is sealed and inserted into the communicating tube cavity. The end cap is sealed and fixedly connected to the assembly tube integrally disposed on the sub-cylinder body. The end cap and the circular filter cartridge together form a detachable structure from the communicating tube cavity.

[0017] Preferably, the metering component includes an impeller box fixed to the main cylinder body, an impeller body rotatably connected to the impeller box, and a counter fixed to the upper side of the main cylinder body. The impeller body, together with the magnetic disk therein, forms a rotating structure on the lower side of the counter, and the counter is driven to work and measure through magnetic coupling transmission.

[0018] Preferably, the monitoring component includes an outer shell and a sensor body integrally fixed on the outer shell. The outer shell is threadedly connected to and sealed together with a round tube seat integrally disposed on the sub-cylinder body, and the outer shell carrying the sensor body is inserted into the sub-cylinder body.

[0019] Preferably, a flow guide is fixedly connected to the sub-cylinder body, and an integrated sealing shell is provided inside the flow guide. An integrated tube column frame is provided on the sealing shell. A turbine component that can rotate inside the flow guide is provided at the lower end of the tube column frame. An integrated square shaft column is provided at the center of the turbine component. A transmission disk that can rotate synchronously with the turbine component is fixedly connected to the upper end of the square shaft column.

[0020] The tube column frame is equipped with a cleaning mechanism that can be rotated by a transmission disc, and the probe part of the sensor body is automatically cleaned periodically by the cleaning mechanism.

[0021] Preferably, a chassis is fixedly connected inside the sealed housing, and a micro generator and an energy storage battery are respectively installed at the right and left ends of the chassis. A driven gear that can rotate inside the sealed housing is fixedly connected to the output end of the micro generator, and a driving gear that can rotate synchronously with the square shaft is meshed on the left side of the driven gear.

[0022] Preferably, the cleaning mechanism includes a plate base forming a lifting structure on the tube column frame, a tube sleeve frame rotatably connected to the middle of the plate base, a cleaning component flipped and connected inside the plate base, and a linkage ring slidably connected to the upper end of the plate base. The cleaning component is arranged in a circular array with the center of the plate base as the center, and the probe part of the sensor body is brushed by the brush on the cleaning component.

[0023] The cleaning component has a tube column fixedly connected inside its shaft tube section, which rotates synchronously with it, and a spring is installed at the rotatable connection between the tube column and the disc base.

[0024] Preferably, the tube sleeve frame is driven by a miniature electric push rod to form a lifting structure on the tube column frame, and the miniature electric push rod is fixedly installed on the chassis.

[0025] Preferably, the upper end of the tube column is provided with an integrated first spiral push block, and the first spiral push block is connected to the second spiral push block, which is integrated at the lower end of the insert column, by a pushing manner. The insert column is integrated on the lower side of the linkage ring, and the insert column forms a sliding structure in the shaft tube of the cleaning member.

[0026] The linkage ring and the transmission disc are connected by a pressing engagement method.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects: the smart water meter with water quality monitoring function can disassemble and clean the filter component separately without affecting other components. In addition, it can be equipped with different types of sensors to realize the integrated monitoring of multiple water quality parameters and meet the use requirements of regular automatic cleaning of sensors to ensure the accuracy of monitoring.

[0028] 1. The circular filter cartridge is sealed and inserted in the connecting pipe cavity. When water flows from the auxiliary cylinder to the main cylinder, the circular filter cartridge located in the connecting pipe cavity can effectively filter out and reel in impurities in the water flow. Unlike the filter components in existing smart water meters, the circular filter cartridge is separated from the metering component. When cleaning the circular filter cartridge, it is not necessary to disassemble the metering component, so the circular filter cartridge can be disassembled independently. That is, it will not interfere with the metering component and will not affect the metering accuracy.

[0029] Furthermore, multiple monitoring components are arranged in a circular array with the center of the sub-cylinder as the center. Each monitoring component is equipped with different sensor bodies according to different water quality monitoring needs. Through diverse water quality monitoring, the functionality of the smart water meter is effectively improved. Water quality monitoring can detect harmful substances in the water in a timely manner to ensure water safety. In addition, by configuring different sensor bodies, the integrated monitoring of multiple water quality parameters can be achieved, and the overall water quality situation can be understood more accurately.

[0030] 2. After the cleaning mechanism is driven to rise, the transmission disc slides due to the pressure between the transmission disc and the linkage ring. The insertion pin pushes the tube column to rotate, causing the cleaning component to flip and unfold to align with the probe part of the sensor body. Through the linkage structure, the cleaning component can be operated to automatically flip and unfold or automatically flip and close. In addition, through the transmission of the transmission disc, the cleaning component follows the disc base to rotate, brushing the probe part of the sensor body, meeting the needs of regular automatic cleaning, ensuring the accuracy of sensor measurement data, and guaranteeing the long-term stable operation of the water quality monitoring system.

[0031] Furthermore, when the cleaning mechanism is performing cleaning work, it is driven by the transmission of the turbine components. When the cleaning mechanism is not performing cleaning work, the turbine components can provide a power source for the power generation and energy storage device composed of the chassis, micro generator and energy storage battery, thus achieving energy self-sufficiency, reducing dependence on external energy, and ensuring normal operation in special circumstances such as power outages.

Detailed Implementation

[0048] 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, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0049] Example 1:

[0050] This invention provides a technical solution: a smart water meter with water quality monitoring function. This addresses the problem that, during use, the filter component of the smart water meter cannot effectively collect filtered impurities, and that cleaning the filter component cannot be performed independently without affecting other metering components, thus impacting operational convenience. The filter component 4 is located within the connecting pipe cavity 3, separated from the metering component 5. When cleaning the filter component 4 is required, it can be disassembled independently without affecting the metering component 5. The circular filter cylinder 7 in the filter component 4 is sealed and inserted into the connecting pipe cavity 3. When water flows through the connecting pipe cavity 3 from the auxiliary cylinder 2 to the main cylinder 1, impurities in the water are filtered and collected by the circular filter cylinder 7.

[0051] In addition, to address the issue that smart water meters have limited functionality and cannot perform diverse water quality monitoring of the water flowing through them, thus affecting their performance, multiple monitoring components 6 are arranged in a circular array with the center of the sub-cylinder 2 as the center. Each monitoring component 6 is equipped with different sensor bodies 13 according to different water quality monitoring needs, such as pH water quality detection sensors, residual chlorine sensors, and turbidity sensors, so that diverse water quality monitoring of the water flow can be performed through different sensor bodies 13.

[0052] This technical solution: Please refer to Figures 1-4 A smart water meter with water quality monitoring function includes a main cylinder 1, an integrated water outlet pipe 101 connected to the right side of the main cylinder 1, an integrated auxiliary cylinder 2 connected to the left side of the main cylinder 1, a connecting pipe 3 between the two, and an integrated water inlet pipe 201 connected to the left side of the auxiliary cylinder 2.

[0053] It also includes a filter assembly 4 and a monitoring assembly 6. The filter assembly 4 is set in the connecting pipe 3. The filter assembly 4 filters out and collects impurities in the water flowing through the smart water meter to prevent impurities in the water flow from interfering with the metering assembly 5 in the main cylinder 1. The filter assembly 4 and the metering assembly 5 are set separately and can be disassembled separately. The monitoring assembly 6 is arranged in a ring array with the center of the auxiliary cylinder 2 as the center. The monitoring assembly 6 performs various water quality monitoring on the water flowing through the smart water meter.

[0054] Specifically, in this technical solution, when using the smart water meter, according to... Figure 1 , Figure 2 and Figure 3 As shown, since the outer edge of the left end of the water inlet pipe 201 is provided with an integrated flange, and since the outer edge of the right end of the water outlet pipe 101 is provided with an integrated flange, the smart water meter is sealed and assembled between the two water supply pipes through the flange in the water inlet pipe 201 and the flange in the water outlet pipe 101.

[0055] Because the inner cylinder wall of the auxiliary cylinder 2 is provided with an integrated connecting ring in the middle, the cylinder cavity of the auxiliary cylinder 2 is divided into an upper cylinder cavity and a lower cylinder cavity from top to bottom through the separation of the connecting ring. Also, because the water inlet pipe 201 is horizontally arranged on the left side of the auxiliary cylinder 2 with an integrated structure, its right end is connected to the lower end of the left cylinder wall of the auxiliary cylinder 2 and connected to the lower cylinder cavity of the auxiliary cylinder 2. A water supply pipe delivers water into the lower cylinder cavity of the auxiliary cylinder 2 through the water inlet pipe 201, and then flows through the lower cylinder cavity of the auxiliary cylinder 2 to fill the upper cylinder cavity of the auxiliary cylinder 2.

[0056] Because the main cylinder 1 has an integrated connecting ring in the middle of its inner wall, the cylinder cavity is divided into an upper cavity and a lower cavity from top to bottom. Furthermore, the connecting pipe 3 has a V-shaped structure with a curved inflection point, and is divided into an upward-sloping left section and a downward-sloping right section. The connecting pipe 3 is located between the auxiliary cylinder 2 and the main cylinder 1, with the opening of the left section abutting against the right side wall of the auxiliary cylinder 2. The upper part of the auxiliary cylinder 2 is connected to the upper cylinder cavity of the auxiliary cylinder 2, and the opening of the right section of the cavity is connected to the lower end of the left side cylinder wall of the main cylinder 1 and connected to the lower cylinder cavity of the main cylinder 1. When the water flows from the upper cylinder cavity of the auxiliary cylinder 2 to the lower cylinder cavity of the main cylinder 1, the water needs to flow through the left and right sections of the connecting pipe 3 in sequence, enter the lower cylinder cavity of the main cylinder 1 through the connecting pipe 3, and then flow through the lower cylinder cavity of the main cylinder 1 to fill the upper cylinder cavity of the main cylinder 1.

[0057] Since the water outlet pipe 101 is an integrated structure horizontally set on the right side of the main cylinder 1, its left end pipe is connected to the upper end of the right side cylinder wall of the main cylinder 1 and connected to the upper cylinder cavity of the main cylinder 1. After the water fills the upper cylinder cavity of the main cylinder 1, it flows into the water outlet pipe 101 and is transported to another section of the water supply pipe through the water outlet pipe 101. Thus, the water flows through the smart water meter completely.

[0058] Since the metering component 5 includes an impeller box 9, an impeller body 10, and a counter 11, its working method is the same as that of the metering mechanism in existing smart water meters. Furthermore, since the impeller box 9 is installed and its middle part is overlapped and fixedly connected to the connecting ring in the main cylinder 1 by bolts, and its upper end is inserted into the upper cylinder cavity of the main cylinder 1, and its lower end is inserted into the lower cylinder cavity of the main cylinder 1, when the water flows through the lower cylinder cavity of the main cylinder 1 to fill the upper cylinder cavity of the main cylinder 1, the water will flow through the impeller box 9.

[0059] Because the impeller box 9 is a circular box structure with the opening facing upwards, its function is the same as that of the rectifier in existing smart water meters. The impeller box 9 has oblique holes arranged in a ring array with its center and the center of the circle on its box wall. Since the impeller body 10 has an integrated shaft column at its center, the impeller body 10 is movably inserted into the box cavity of the impeller box 9 after it is installed. The lower end of the shaft column is rotatably inserted into the box cavity wall of the impeller box 9, so that the impeller body 10 is positioned in a movable state inside the impeller box 9. When the water flows through the impeller box 9, the water flow entering the impeller box 9 is rectified and guided by the specific arrangement of the oblique holes in the impeller box 9, so as to ensure that the water flow has a stable impact on the impeller body 10 and drive the impeller body 10 to rotate stably in the box cavity of the impeller box 9.

[0060] Since the upper end of the upper cylinder cavity inside the main cylinder body 1 is in an open state, its opening is set as the cylinder cavity port of the main cylinder body 1. An integrated flange is provided on the outer edge of the cylinder cavity port in the main cylinder body 1. After the counter 11 is installed, its lower end is inserted into the upper cylinder cavity of the main cylinder body 1, and its middle part overlaps and is fixedly connected to the flange in the main cylinder body 1 by bolts. Its upper end is placed outside the main cylinder body 1. In addition, a sealing gasket is provided at the joint between the counter 11 and the flange in the main cylinder body 1. The sealing treatment after the two are assembled is performed by the sealing gasket.

[0061] Since the lower side of the counter 11 is fixedly connected with a housing for protecting the magnetic disk in the impeller body 10 by bolts, and since the upper end of the shaft of the impeller body 10 is fixedly connected with a magnetic disk at the same rotation center, after the impeller body 10 is installed, the upper end of the shaft, along with the magnetic disk, is inserted into the housing on the lower side of the counter 11. When the impeller body 10 rotates due to the impact of water flow, it drives the magnetic disk to rotate synchronously. Through the principle of magnetic coupling transmission, when the magnetic disk rotates, its magnetic field will synchronously drive the magnetic components inside the counter 11. After the magnetic components inside the counter 11 are driven to rotate, they drive the gear set inside the counter 11 to operate and perform the measurement work (the working principle of the counter 11 is existing technology and is not described in the accompanying drawings of the specification).

[0062] Because an electronic conversion device (such as a Hall sensor) is installed on the gear set inside the counter 11, the rotation of the gear set can be converted into electrical pulse signals. Also, because a smart box is fixedly configured on the upper end of the counter 11, the smart box integrates functional modules such as a data acquisition module, a microprocessor module, and a wireless communication module (the smart box and its working principle are existing technologies and are not described in the accompanying drawings). The data acquisition module in the smart box collects the electrical pulse signals generated when the counter 11 is running, processes and calculates the water volume through the microprocessor module, and then remotely uploads the data through the wireless communication module, realizing remote automatic collection of water consumption data.

[0063] Meanwhile, in the above technical solutions, according to Figure 1 and Figure 2 As shown, the water outlet pipe 101 is segmented with a left section and a right section. The right section of the water outlet pipe 101 is curved downward and extends horizontally to the right. This makes the right end of the water outlet pipe 101 and the left end of the water inlet pipe 201 on the same horizontal central axis, which facilitates the horizontal assembly of the smart water meter on the water supply pipeline.

[0064] Meanwhile, in the above technical solutions, according to Figure 2 and Figure 3As shown, the main cylinder 1 is set in a vertical state with the cylinder cavity opening facing upwards. Through the cylinder cavity opening in the main cylinder 1, components such as the impeller box 9, impeller body 10, and counter 11 can be disassembled from the main cylinder 1, which facilitates later maintenance and repair.

[0065] Meanwhile, in the above technical solutions, according to Figure 2 and Figure 3 As shown, since the main cylinder 1 has a cylindrical structure, the center of the connecting ring coincides with the center of the main cylinder 1. The connecting ring in the main cylinder 1 is used for the assembly of the impeller box 9 inside the main cylinder 1, so that the impeller box 9 is located in the center of the cylinder cavity inside the main cylinder 1 after assembly, ensuring that the water flow enters the impeller box 9 evenly from all sides, avoiding the phenomenon of flow deviation, and thus helping the impeller body 10 to maintain dynamic balance when rotating.

[0066] Meanwhile, in the above technical solutions, according to Figure 2 As shown, an electric ball valve is installed at the right end of the smart box in counter 11. After the electric ball valve is assembled, the ball valve body is sealed and installed at the junction of the left and right sections of the water outlet pipe 101 (the electric ball valve and its working principle are existing technologies and are not described in the attached drawings of the manual). When the water consumption or water quality is abnormal, the wireless communication module in the smart box receives the instruction signal from the remote control device, identifies the instruction signal through the microprocessor module, and controls the electric ball valve to close automatically. Conversely, the same applies, realizing the remote automatic switching of the smart water meter.

[0067] In addition, the connection method at the segment of the water outlet pipe 101 is that the right segment of the pipe is inserted and fixed to the left segment of the pipe with bolts, so that the water outlet pipe 101 can be separated to assemble the electric ball valve in the intelligent box of the counter 11.

[0068] Specifically, in this technical solution, the smart water meter filters and collects impurities in the water flow during use, according to... Figure 2 and Figure 3 As shown, since the wall of the left section of the connecting tube 3 is provided with an integrated concentric limiting ring, and since the outer edge of the cylinder opening of the circular filter 7 is convex outward, after the circular filter 7 is installed, the outer edge of the cylinder opening presses against the limiting ring of the left section of the connecting tube 3 to limit the placement position of the circular filter 7 in the connecting tube 3.

[0069] Since the left side of the circular filter cylinder 7 has an open opening, after the circular filter cylinder 7 is installed, it is inserted into the left section of the connecting pipe 3, and its opening is facing the upper cylinder cavity of the auxiliary cylinder 2. When the water flows from the upper cylinder cavity of the auxiliary cylinder 2 through the connecting pipe 3 and into the lower cylinder cavity of the main cylinder 1, the water will flow through the circular filter cylinder 7, and the impurities in the water will be filtered out and collected in its cylinder cavity.

[0070] Since a sealing ring is fixedly fitted to the outer edge of the cylindrical filter 7, after the cylindrical filter 7 is inserted and plugged in, the sealing ring is tightly fitted to the cavity wall of the left section of the connecting pipe 3, thus sealing the outer edge of the cylindrical filter 7 and the left section of the connecting pipe 3. This prevents water that has not been filtered by the cylindrical filter 7 from leaking directly from the joint between the cylindrical filter 7 and the connecting pipe 3, ensuring the effectiveness of filtration.

[0071] Meanwhile, in the above technical solutions, according to Figure 2 and Figure 3 As shown, the outer diameter of the cylindrical body of the circular filter cartridge 7 is smaller than the diameter of the left section of the connecting pipe 3. This ensures that after the circular filter cartridge 7 is inserted into the left section of the connecting pipe 3, a gap is left between the two, thus ensuring that the water flows smoothly around the circular filter cartridge 7 and enhancing the filtration efficiency.

[0072] Specifically, in this technical solution, during the individual disassembly operation of the circular filter cartridge 7, according to... Figure 2 and Figure 3 As shown, since the assembly tube 202 is aligned with the inclined orientation of the left section of the connecting tube 3 and is integrally set on the left side of the auxiliary cylinder 2, and its right end port is connected to the upper end of the left cylinder wall of the auxiliary cylinder 2 and connected to the upper cylinder cavity of the auxiliary cylinder 2, and its right end port corresponds to the cavity port of the left section of the connecting tube 3, and since the diameter of the tube cavity in the assembly tube 202 is larger than the diameter of the widest part of the outer side of the round filter 7, the round filter 7 can freely enter and exit the assembly tube 202 when the end cap 8 is disassembled.

[0073] Since the end cap 8 has integrated strip plate parts on both the front and rear sides, the strip plate parts are in line with the inclined direction of the left section of the cavity in the connecting tube 3. Since the right ends of the two strip plate parts in the end cap 8 are respectively welded to the front and rear sides of the cylinder opening of the circular filter cylinder 7, the connection between the end cap 8 and the circular filter cylinder 7 is made through the strip plate parts in the end cap 8, so that the circular filter cylinder 7 can move synchronously with the end cap 8. That is, the circular filter cylinder 7 can be disassembled and assembled in the connecting tube 3 by operating the end cap 8.

[0074] Since the filter assembly 4 includes a circular filter cartridge 7 and an end cap 8, it is set separately from the metering assembly 5. That is, the circular filter cartridge 7 is detached from the metering assembly 5. When the circular filter cartridge 7 is disassembled, it can be disassembled separately without interfering with the metering assembly 5.

[0075] Meanwhile, in the above technical solutions, according to Figure 2 and Figure 3 As shown, the outer edge of the left end of the assembly pipe 202 is provided with an integrated flange. After the end cap 8 is installed, it is snapped and fixed to the flange of the assembly pipe 202 with bolts. A sealing gasket is provided at the snap-fit ​​point between the end cap 8 and the assembly pipe 202. The sealing gasket is used to seal the two after assembly.

[0076] In addition, the strip plate in the end cap 8 passes through the upper cylinder cavity of the sub-cylinder 2. The strip plate will not obstruct the upper cylinder cavity of the sub-cylinder 2, allowing water to flow smoothly into the connecting pipe cavity 3.

[0077] Specifically, in this technical solution, the smart water meter performs various water quality monitoring operations on the water flow during use, based on... Figure 2 and Figure 4 As shown, the circular tube seat 203 is vertically installed on the outside of the auxiliary cylinder 2 in an integrated structure, and its cavity is connected to the upper cylinder cavity of the auxiliary cylinder 2. The outer shell 12 is nail-shaped, divided into a nail rod part facing the auxiliary cylinder 2 and a nail tail part facing away from the auxiliary cylinder 2. After the sensor body 13 is installed, it is inserted into the center of the outer shell 12 and is sealed and fixed to the outer shell 12 in an integrated structure. Its tail end, along with the data cable, passes through the outer shell. The tail of the nail of the outer shell 12 extends outward, and the probe part at its head extends outward through the nail rod part of the outer shell 12. After the outer shell 12 is connected to the round tube seat 203, the nail rod part in the outer shell 12 extends through the tube cavity of the round tube seat 203 and into the upper cylinder cavity of the sub-cylinder 2, so that the nail rod part in the outer shell 12 carries the probe part at the head of the sensor body 13 and inserts it into the upper cylinder cavity of the sub-cylinder 2, and makes the probe part at the head of the sensor body 13 directly contact the water flowing through the sub-cylinder 2.

[0078] Since multiple monitoring components 6 are arranged in a ring array on the sub-cylinder 2, each monitoring component 6 can be equipped with different types of sensor bodies 13. When the sensor body 13 is a pH water quality detection sensor, it is used to detect the acidity or alkalinity of the water. When the sensor body 13 is a residual chlorine sensor, it is used to detect the disinfectant residue in the water. When the sensor body 13 is a turbidity sensor, it is used to detect the suspended particle content in the water. That is, different types of sensor bodies 13 can be freely combined according to the water quality monitoring needs to meet the purpose of water quality diversity monitoring.

[0079] Meanwhile, in the above technical solutions, according to Figure 2 and Figure 4 As shown, after the outer shell 12 is installed, the nail rod part is threadedly connected to the cavity wall of the round tube seat 203, and the nail tail part presses against and fits into the cavity opening of the round tube seat 203. A sealing gasket is provided at the point where the nail tail part of the outer shell 12 presses against the round tube seat 203, and the sealing treatment is performed after the two are connected by the sealing gasket.

[0080] In addition, the tail of the nail in the outer casing 12 is set in the shape of a hexagonal nut, which can be turned by an external wrench. That is, the sensor body 13 can be disassembled and assembled on the auxiliary cylinder 2 through the outer casing 12.

[0081] Meanwhile, in the above technical solutions, according to Figure 2 and Figure 4 As shown, when some monitoring components 6 are not involved in the monitoring work, an outer shell 12 without a sensor body 13 can be screwed and fixed onto the current round tube seat 203 to seal the current round tube seat 203, thereby not affecting the normal operation of the smart water meter.

[0082] Meanwhile, in the above technical solutions, according to Figure 2 and Figure 4 As shown, when the sensor body 13 needs to monitor water in a static state, a check valve can be installed at the water inlet pipe 201 (wherein the check valve is existing technology and is not described in the attached drawings of the specification). By controlling the closing of the electric ball valve in the intelligent box of the counter 11, closed cavities are formed in the main cylinder 1 and the auxiliary cylinder 2 respectively, so that water fills and stays in the cylinder cavity of the auxiliary cylinder 2, and the water in the auxiliary cylinder 2 is in a static state.

[0083] Example 2:

[0084] Based on Embodiment 1, please refer to the following: Figures 5-14 The technical solution shown requires various water quality monitoring sensors when monitoring the water flow through a smart water meter. The probe of the water quality monitoring sensor is inserted into the smart water meter and comes into direct contact with the water being measured. Due to impurities such as suspended particles, minerals, and flocculent matter in the water flow, these impurities easily adhere to the probe, forming dirt that can hinder or affect data collection and lead to data distortion. To address the issue of the probe being contaminated by impurities in the water flow and thus unable to meet the requirement for regular automatic cleaning, a micro-electric push rod 30 drives the cleaning mechanism 18 to rise, aligning it with the transmission disc 17. The cleaning component 26 in the cleaning mechanism 18 automatically flips and unfolds to align with the probe of the sensor body 13. Driven by the transmission disc 17, the cleaning mechanism 18 rotates, allowing the cleaning component 26 to brush the probe of the sensor body 13 using its brush.

[0085] Specifically, in this technical solution, the cleaning mechanism 18 is operated by a miniature electric push rod 30 to perform lifting and lowering movements, according to... Figure 6 , Figure 8 , Figure 10 and Figure 12As shown, the cavity inside the sealed housing 15 is divided into an upper cavity and a lower cavity from top to bottom. The miniature electric actuator 30 and the chassis 19 are both placed in the upper cavity of the sealed housing 15. After the miniature electric actuator 30 is installed, it is fixed to the lower side wall of the chassis 19 by bolts. Its output end moves through the upper cavity wall of the chassis 19 and the sealed housing 15 and extends outward. Since the miniature electric actuator 30 is connected to the control motherboard in the chassis 19, the energy storage battery 21 provides power to the miniature electric actuator 30. The miniature electric actuator 30 is started to extend and retract through the control motherboard in the chassis 19.

[0086] Since the lower end of the tube sleeve 25 is fitted with a connecting ring and fixed with bolts, the miniature electric push rod 30 is symmetrically arranged about the vertical central axis of the chassis 19. The output ends of the two miniature electric push rods 30 are respectively inserted and fixed to the front and rear sides of the connecting ring in the tube sleeve 25 with bolts. Since the ring cavity of the connecting ring in the tube sleeve 25 is correspondingly connected to the tube cavity of the tube sleeve 25, after the tube sleeve 25 and the tube column frame 1501 are assembled, the tube sleeve 25 and the connecting ring therein are connected to the tube column frame 1501 in a movable sleeve manner. When the miniature electric push rod 30 is working in telescopic operation, it drives the tube sleeve 25 to move up and down on the tube column frame 1501.

[0087] Because the longitudinal section of the disc base 24 is in the shape of an "I", it is divided into three parts: a prism in the middle, a first disc on the upper side of the prism, and a second disc on the lower side of the prism. A bearing is engaged at the lower cavity of the prism in the disc base 24. Since the outer edge of the tube opening at the upper end of the tube sleeve 25 protrudes outward, after the tube sleeve 25 is assembled with the disc base 24, the upper end of the tube sleeve 25, along with the protruding part, is movably engaged in the cavity of the prism in the disc base 24, and its lower end moves through the lower cavity of the prism in the disc base 24 and protrudes outward. Its lower end is also engaged with the bearing on the prism in the disc base 24, so that the tube sleeve 25 is movably positioned in the prism of the disc base 24. That is, the disc base 24 and the tube sleeve 25 form a synchronous lifting and lowering motion structure.

[0088] Since the plate base 24 and the tube column frame 1501 are assembled, the tube column frame 1501 moves through the column cavity of the prism in the plate base 24. When the tube sleeve frame 25 is driven to move up and down, it drives the plate base 24 to move up and down synchronously on the tube column frame 1501.

[0089] Since the cleaning mechanism 18 includes a disk base 24, a sleeve holder 25 rotatably connected to the middle of the disk base 24, a cleaning member 26 flip - connected within the disk base 24, and a linkage ring 27 slidably connected to the upper end of the disk base 24. That is, the disk base 24 serves as the bearing body, and its displacement movement is equivalent to the displacement movement of the cleaning mechanism 18. When the disk base 24 is driven to move upward, the cleaning mechanism 18 is operated to move upward on the pipe column frame 1501. Conversely, when the disk base 24 is driven to move downward, the cleaning mechanism 18 is operated to move downward on the pipe column frame 1501.

[0090] Meanwhile, in the above - mentioned technical solution, according to Figure 12 As shown, a sealing sleeve is installed at the insertion connection between the output end of the micro - electric push rod 30 and the cavity wall of the upper cavity of the sealing housing base 15. The sealing treatment of the insertion part between the two is carried out through the sealing sleeve to prevent water from entering the sealing housing base 15 when the micro - electric push rod 30 works.

[0091] Specifically, in this technical solution, the cleaning member 26 in the cleaning mechanism 18 automatically flips and expands. According to Figure 5 、 Figure 6 、 Figure 10 、 Figure 11 、 Figure 13 and Figure 14 As shown, after the cleaning mechanism 18 is driven to move upward on the pipe column frame 1501, the cleaning mechanism 18 is docked with the transmission disk 17. Since a limiting ring disk is clamped and fixedly connected to the upper side of the first disk in the disk base 24 through bolts, and the longitudinal section of the limiting ring disk is in a "convex" - shaped structure. Also, since a "concave" - shaped ring cavity is provided within the linkage ring 27, after the linkage ring 27 is placed, it is movably sleeved on the limiting ring disk at the upper end of the disk base 24. Through the mutual cooperation between the "convex" - shaped limiting ring disk in the disk base 24 and the "concave" - shaped ring cavity within the linkage ring 27, the linkage ring 27 is positioned in an active state at the upper end of the disk base 24;

[0092] Since in the initial state of the linkage ring 27, it is set to extend beyond the limiting ring disk in the disk base 24, and the extended distance dimension of the linkage ring 27 is greater than the maximum sliding distance dimension of the linkage ring 27. When the cleaning mechanism 18 is docked with the transmission disk 17, the linkage ring 27 and the transmission disk 17 are connected in a pressing manner, so that the linkage ring 27 is pushed and slides downward at the upper end of the disk base 24;

[0093] Since the cleaning members 26 are arranged in a circular array with the center of the disk base 24 as the center of the circle, and since the plug members 31 are integrally and vertically arranged on the lower side of the linkage ring 27 and are arranged in a circular array with the center of the ring of the linkage ring 27 as the center of the circle, each plug member 31 corresponds to each cleaning member 26 one by one;

[0094] Since the end of the cleaning component 26 facing the disc base 24 is the inward end and the end away from the disc base 24 is the outward end, the inward end of the cleaning component 26 is provided with an integrated shaft tube. Also, since after the insert 31 is assembled with the cleaning component 26, the lower end of the insert 31 is movably inserted into the cavity of the shaft tube of the cleaning component 26. When the linkage ring 27 is driven to slide downward, the linkage ring 27 drives the insert 31 to move downward synchronously, so that the insert 31 slides downward in the shaft tube of the cleaning component 26.

[0095] Because the upper end of the tubular component 28 is integrally provided with a first spiral pusher 2801, and the first spiral pusher 2801 is provided with a spiral inclined wall, and is mirrored about the vertical central axis of the tubular component 28, after the tubular component 28 and the cleaning component 26 are assembled, the upper end of the tubular component 28, together with the first spiral pusher 2801, is inserted into the cavity of the central tube of the cleaning component 26, and the tubular component 28 is fixedly connected to the central tube of the cleaning component 26 by bolts. Furthermore, because the lower end of the insert component 31 is integrally provided with a second spiral pusher... The specifications and dimensions of the second spiral pusher 3101 are adapted to those of the first spiral pusher 2801. It is also provided with a spiral inclined wall and is also mirrored about the vertical central axis of the insert 31. After the insert 31 is assembled with the cleaning component 26, the lower end of the insert 31, together with the second spiral pusher 3101, is movably inserted into the cavity of the central tube of the cleaning component 26, so that the second spiral pusher 3101 and the first spiral pusher 2801 are in contact, and the spiral inclined walls on the two are pressed together.

[0096] Since the maximum sliding distance of the second spiral pusher 3101 on the first spiral pusher 2801 is greater than the maximum sliding distance of the insert 31, when the insert 31 is driven to slide downward, the spiral inclined wall in the second spiral pusher 3101 slides along the spiral inclined wall in the first spiral pusher 2801, and the second spiral pusher 3101 generates a pushing force on the first spiral pusher 2801. After being pushed, the first spiral pusher 2801 drives the tube column 28 to move.

[0097] Since the tubular component 28 is assembled inside the central tube of the cleaning component 26, the two form a coaxial rotating structure. Furthermore, since the first disc in the disk base 24 has an integrated structure with vertically arranged shafts, and the shafts are arranged in a circular array with the center of the first disc as the center, each shaft corresponds to each cleaning component 26. After the tubular component 28 is assembled with the disk base 24, its lower end is movably sleeved on the central shaft of the disk base 24. When driven, the tubular component 28 rotates on the first disc in the disk base 24, and drives the central tube of the cleaning component 26 to move synchronously.

[0098] Since a spring 29 is installed at the rotating connection between the column 28 and the disk base 24, the spring 29 is configured in a clockwork shape, with its inner end integrally set on the column 28 and its outer end fixedly snapped onto the prism in the disk base 24. When the column 28 is driven to rotate, the spring 29 is subjected to force and undergoes elastic deformation.

[0099] Because the second disk in the disk base 24 has shaft holes arranged in a ring around its center, the center of the shaft holes on the second disk in the disk base 24 and the center of the shaft column on the first disk in the disk base 24 are on the same vertical central axis. Furthermore, because a pre-existing gap is left between the first and second disks in the disk base 24 to form an annular groove, and because the upper end of the shaft tube in the cleaning member 26 is provided with an integrated limiting ring, after the cleaning member 26 is installed, its inward end is inserted into the annular groove of the disk base 24, and the upper end of its shaft tube is movably inserted... The cleaning component 26 is positioned in the annular groove of the disk base 24 by a limiting ring on the central shaft of the cleaning component 26, which limits the contact of the first disk in the disk base 24, and by a column member 28, which limits the contact of the second disk in the disk base 24. This allows the central shaft of the cleaning component 26 to be positioned in a movable state within the annular groove of the disk base 24. After the central shaft of the cleaning component 26 moves synchronously with the column member 28, it rotates within the annular groove of the disk base 24, thereby driving the cleaning component 26 to automatically flip and unfold within the annular groove of the disk base 24.

[0100] As the width of the cleaning component 26 gradually increases from its inner end to its outer end, and as a brush is fixedly attached to the outer end of the cleaning component 26, which can be disassembled and replaced on the cleaning component 26, the cleaning component 26 automatically flips and unfolds to align with the probe part of the sensor body 13, so that the sensor body 13 corresponds to the center position of the brush in the cleaning component 26.

[0101] Meanwhile, in the above technical solutions, according to Figure 10 and Figure 12 As shown, the annular cavity of the limiting ring in the disc base 24 is connected to the upper column cavity of the prism in the disc base 24. After the disc base 24 is assembled with the column frame 1501, the limiting ring in the disc base 24 is connected to the column frame 1501 by a movable sleeve, so that the limiting ring in the disc base 24 does not affect the lifting and lowering movement of the disc base 24.

[0102] Specifically, in this technical solution, the transmission disc 17 drives the cleaning mechanism 18 to rotate, performing a brushing operation on the probe portion of the sensor body 13. Figure 5 , Figure 6 , Figure 7 , Figure 10 and Figure 11As shown, the guide shroud 14 is a circular tube cover. After the guide shroud 14 is installed, its upper end overlaps and is fixedly connected to the connecting ring in the sub-cylinder 2 by bolts. Its upper end cover opening is connected to the upper cylinder cavity of the sub-cylinder 2, and its lower end is inserted into the lower cylinder cavity of the sub-cylinder 2. Its lower end cover opening is connected to the lower cylinder cavity of the sub-cylinder 2. The guide shroud 14 is used to guide the water flow from the lower cylinder cavity of the sub-cylinder 2 to the upper cylinder cavity of the sub-cylinder 2.

[0103] Since the sealing housing 15 is vertically positioned at the center of the flow guide shroud 14, its lower end is inserted into the cavity of the flow guide shroud 14, and its upper end passes through the upper opening of the flow guide shroud 14 and is inserted into the upper cavity of the auxiliary cylinder 2. Furthermore, since integrated connecting strips are horizontally arranged at the four corners of the lower end of the sealing housing 15, the end of the connecting strip opposite to the sealing housing 15 is integrally arranged on the cavity wall of the flow guide shroud 14. Through the arrangement of the connecting strips, the sealing housing 15 and the flow guide shroud 14 are fixedly assembled (in addition, through the arrangement of the connecting strips, the cavity of the flow guide shroud 14 will not be obstructed, allowing the water flow to pass smoothly through the cavity of the flow guide shroud 14).

[0104] Since the tube column 1501 is an integral structure set at the center of the sealing housing 15, its center is on the same vertical central axis as the center of the flow guide 14. The upper end of the tube column 1501 extends vertically upward from the upper side of the sealing housing 15, and its lower end extends vertically downward from the lower side of the sealing housing 15. In addition, the tube column 1501 passes through the upper cavity of the sealing housing 15 and is connected to the lower cavity of the sealing housing 15.

[0105] Since the turbine component 16 is installed and movably inserted into the cavity of the guide shroud 14, and its center position is movably sleeved on the lower end of the tube column frame 1501, the turbine component 16 is positioned in a movable state inside the guide shroud 14. When the water flows through the guide shroud 14, the impact force of the water flow applies a torque to the blades in the turbine component 16, so that the turbine component 16 forms a rotating structure at the lower end of the tube column frame 1501.

[0106] Since the square shaft column 1601 is vertically set at the rotation center of the turbine component 16 in an integrated structure, after the turbine component 16 is assembled with the column frame 1501, the square shaft column 1601 moves through the column cavity of the column frame 1501, and its upper end extends outward from the upper end of the column cavity of the column frame 1501. Since the center position of the transmission disk 17 is movably sleeved on the upper end of the column frame 1501 after it is installed, and its center position is sleeved and fixedly connected to the upper end of the square shaft column 1601 by bolts, when the turbine component 16 is driven to rotate, the square shaft column 1601 moves with the turbine component 16 and can rotate in the column cavity of the column frame 1501. The transmission disk 17 follows the turbine component 16 through the transmission of the square shaft column 1601 to form a synchronous rotation structure, so that the transmission disk 17 rotates at the upper end of the column frame 1501.

[0107] Since the lower sidewall of the transmission disc 17 is set with a disc tooth structure, and the upper sidewall of the linkage ring 27 is also set with a disc tooth structure, when the cleaning mechanism 18 moves upward, the cleaning component 26 automatically flips and unfolds. At this time, the linkage ring 27 presses against the transmission disc 17. The two are connected together by pressing against each other through the disc tooth structure. That is, the linkage ring 27 and the transmission disc 17 can form a synchronous movement structure.

[0108] Because the linkage ring 27 is restricted by the limiting ring in the disc base 24 after it is installed, the linkage ring 27 is positioned in a movable state at the upper end of the disc base 24. Also, because each insert 31 on the lower side of the linkage ring 27 is movably inserted into the shaft tube of each corresponding cleaning component 26, the linkage ring 27 is restricted to linear sliding motion on the disc base 24. When the transmission disc 17 drives the linkage ring 27 to rotate, the linkage ring 27 will not rotate on the disc base 24, but will only drive the disc base 24 and the cleaning component 26 to rotate synchronously on the tube sleeve frame 25.

[0109] Since the disc base 24 and the tube sleeve frame 25 are connected by rotation, when the linkage ring 27 rotates with the transmission disc 17, the disc base 24 carries the unfolded cleaning component 26 to rotate and work. The brush on the cleaning component 26 brushes the probe part of the sensor body 13, thus realizing the need for regular automatic cleaning of the probe part of the sensor body 13.

[0110] Meanwhile, in the above technical solutions, according to Figure 5 and Figure 6 As shown, the sub-cylinder body 2 has a cylindrical structure, in which the center of the connecting ring coincides with the center of the sub-cylinder body 2. The connecting ring in the sub-cylinder body 2 is used for the assembly of the fairing 14 inside the sub-cylinder body 2. The function of the connecting ring is the same as that of the connecting ring in the main cylinder body 1, so that the fairing 14 is located at the center of the cylinder cavity inside the sub-cylinder body 2 after assembly. Similarly, it helps the turbine component 16 maintain dynamic balance when rotating.

[0111] Meanwhile, in the above technical solutions, according to Figure 5 and Figure 6 As shown, the auxiliary cylinder 2 is an integrated structure located on the left side of the main cylinder 1, parallel to the main cylinder 1, and also in a vertical state with the cylinder cavity opening facing upwards. Since the upper end of the upper cylinder cavity inside the auxiliary cylinder 2 is in an open state, its opening is set as the cylinder cavity opening of the auxiliary cylinder 2. Through the cylinder cavity opening in the auxiliary cylinder 2, components such as the guide shield 14, sealing housing 15, turbine component 16, and cleaning mechanism 18 can be disassembled from the auxiliary cylinder 2, which is convenient for maintenance and repair.

[0112] In addition, an integrated flange is provided on the outer edge of the cylinder cavity in the secondary cylinder body 2. The flange in the secondary cylinder body 2 is snapped and fixed to the cylinder head with bolts, and a sealing gasket is provided at the snapping point between the two. The cylinder head seals and covers the cylinder cavity in the secondary cylinder body 2.

[0113] Meanwhile, in the above technical solutions, according to Figure 7 As shown, since a mechanical seal (which is prior art and not described in the accompanying drawings) is installed at the movable joint between the turbine component 16 and the tube column 1501, the rotational sealing treatment at the assembly point of the two is performed by the mechanical seal to prevent water from entering the sealing housing 15 during the operation of the turbine component 16.

[0114] Since a mechanical seal (which is existing technology and not described in the accompanying drawings) is installed at the movable joint between the transmission disc 17 and the column frame 1501, the mechanical seal provides rotational sealing at the assembly point of the two parts, preventing water from entering the sealing housing 15 during operation of the transmission disc 17.

[0115] Meanwhile, in the above technical solutions, according to Figure 6 , Figure 9 and Figure 13 As shown, the cleaning component 26 has an arc-shaped structure and is spirally bent. The cleaning component 26 flips and unfolds on the disc base 24. The curved surface of the cleaning component 26 is set in the same direction as the curved surface of the blade in the turbine component 16. That is, after the cleaning component 26 flips and unfolds, it can also form a turbine-shaped structure, which can follow the rotation rhythm of the turbine component 16 without causing interference.

[0116] In addition, according to the above, after the cleaning mechanism 18 moves downward, the pressure between the linkage ring 27 and the transmission disk 17 is released. The elastic deformation of the spring 29 is used to reset the cleaning component 26, which automatically flips and closes on the disk base 24, and the cleaning component 26 loses contact with the probe part of the sensor body 13, so as not to affect the detection work of the sensor body 13.

[0117] Specifically, in this technical solution, the chassis 19, the micro generator 20, and the energy storage battery 21 constitute a power generation and energy storage device. When the cleaning mechanism 18 is no longer performing cleaning work, the turbine component 16 continues to rotate, generating and storing energy to provide electrical power support for the micro electric push rod 30. Figure 7 , Figure 8 and Figure 9As shown, after the turbine component 16 is assembled with the tube column frame 1501, the lower end of the square shaft column 1601 is exposed in the lower cavity of the sealing housing 15. Since the center of the drive gear 23 is provided with an integrated shaft tube, after the drive gear 23 is installed, the shaft tube is sleeved together with the square shaft column 1601 exposed in the lower cavity of the sealing housing 15. Through the square structure of the square shaft column 1601, the drive gear 23 and the square shaft column 1601 are engaged and connected together. When the turbine component 16 rotates due to the impact of water flow, it drives the square shaft column 1601 to rotate in the column cavity of the tube column frame 1501. Through the engagement between the drive gear 23 and the square shaft column 1601, the drive gear 23 moves synchronously with the square shaft column 1601.

[0118] Since bearings are fixedly attached to both the upper and lower ends of the shaft tube of the drive gear 23, the drive gear 23 is placed in the lower cavity of the sealing housing 15, and the upper and lower ends of the shaft tube are respectively connected with the bearings and movably inserted into the two side walls of the lower cavity, so that the drive gear 23 is positioned in a movable state in the sealing housing 15. When the drive gear 23 is driven, it rotates in the lower cavity of the sealing housing 15.

[0119] Since the driven gear 22 has an integrated shaft at its center, with bearings fixedly attached to both ends of the shaft, the driven gear 22 is placed in the lower cavity of the sealing housing 15. The upper and lower ends of the shaft, along with the bearings, are movably inserted into the two side walls of the lower cavity, so that the driven gear 22 is positioned in a movable state within the sealing housing 15. Since the driven gear 22 is meshed with the driving gear 23, when the driving gear 23 rotates, the driven gear 22 is driven to rotate within the lower cavity of the sealing housing 15 through the meshing transmission between the driven gear 22 and the driving gear 23.

[0120] Since the sealing housing 15 is used to seal and protect the power generation and energy storage device composed of the chassis 19, the micro generator 20 and the energy storage battery 21, and since the chassis 19 has a ring structure, after it is installed, it is movably connected to the tube column frame 1501 inserted into the upper shell cavity of the sealing housing 15, and it is fixedly connected to the upper shell cavity wall of the sealing housing 15 by bolts. Since the left and right ends of the lower side wall of the chassis 19 are vertically downwardly provided with an integrated connecting frame, after the micro generator 20 is installed, it is fixedly installed on the connecting frame at the right end of the chassis 19 by bolts, and the output end is fixedly inserted into the upper end of the shaft column of the driven gear 22. After the driven gear 22 is driven to rotate, it drives the output end of the micro generator 20 to rotate synchronously.

[0121] Since the control motherboard (which is existing technology and not described in the accompanying drawings) is installed inside the chassis 19, the micro generator 20 is connected to the control motherboard in the chassis 19. Through the principle of electromagnetic induction, the micro generator 20 generates electrical energy after being driven to operate. Since the energy storage battery 21 is fixedly installed on the connecting bracket at the left end of the chassis 19, the energy storage battery 21 is connected to the control motherboard in the chassis 19. The electrical energy generated by the micro generator 20 can be collected in the energy storage battery 21.
