Description

Technical Field

[0001] This application relates to the field of water meter technology, and more specifically, to a smart water meter based on hydropower generation. Background Technology

[0002] Traditional smart water meters are typically powered by an external power source or batteries.

[0003] If the external power supply is interrupted unexpectedly, the water meter will not function properly.

[0004] Battery-powered systems require regular maintenance, and poor management can easily lead to power outages due to battery depletion. Summary of the Invention

[0005] The purpose of this application is to provide a smart water meter based on hydropower generation, which effectively reduces dependence on external power sources and the frequency of manual maintenance, can ensure long-term stable operation of the water meter, and reduces the impact of power outages on the operation of the water meter.

[0006] The embodiments of this application are implemented as follows: A smart water meter based on hydropower generation includes: a water meter body, a pipeline water flow power generation module, and an energy storage module.

[0007] Both the water meter body and the pipeline water flow power generation module are installed in the water supply pipeline.

[0008] The power output terminal of the pipeline water flow power generation module is electrically connected to the charging interface of the energy storage module, and the power supply interface of the energy storage module is electrically connected to the water meter body.

[0009] Furthermore, smart water meters based on hydropower also include a filtration mechanism.

[0010] The filtration system is also installed on the water supply line.

[0011] The filtration mechanism is located upstream of both the water meter body and the pipeline water flow power generation module.

[0012] Furthermore, the filtration mechanism includes: a diversion box, an input pipe, an output pipe, a first drain pipe, a control core, and a control module.

[0013] The diversion box has a diversion cavity, in which a guide tube and a filter are installed. One end of the guide tube is connected to and sealed by the inner wall of the diversion cavity, and the other end of the guide tube is sealed by a first sealing plate.

[0014] The filter element is cylindrical, with one end connected to the side of the first sealing plate away from the guide tube, and the other end of the filter element is sealed by the second sealing plate.

[0015] The first sealing plate has a first connecting hole that connects the guide tube and the filter element.

[0016] The input pipe is connected to the shunt chamber of the shunt box, and the output pipe is connected to the guide pipe.

[0017] The side wall of the diversion box is provided with a drain port that communicates with the inner cavity of the diversion box, and the first drain pipe is connected to the outer side wall of the diversion box and communicates with the drain port.

[0018] The guide tube and the filter element are coaxially arranged, and the inner diameter of the filter element is larger than the diameter of the first connecting hole.

[0019] The control core is set along the axial direction of the guide tube.

[0020] The control core penetrates the side wall of the diversion box and extends into the guide tube. The control core extends into the filter element through the first connecting hole. The control core penetrates the second sealing plate and extends further toward the drain outlet.

[0021] Along the axial direction of the guide tube, the control core slides against the side wall of the diversion box and the second sealing plate and slides to seal.

[0022] The control core is fixedly connected to a first sealing element and a second sealing element. The first sealing element is located inside the filter element, and the second sealing element is located inside the diversion cavity and outside the filter element.

[0023] The control core has a first sliding stop and a second sliding stop. When the control core is at the first sliding stop, the first sealing element separates from the first sealing plate, and the second sealing element closes the drain port. When the control core is at the second sliding stop, the first sealing element closes the first connecting hole, and the second sealing element separates from the inner wall of the diversion cavity.

[0024] The control module includes a controller and a driver.

[0025] Both the controller and the driver are electrically connected to the power supply interface of the energy storage module, and the driver is driven in conjunction with the control core.

[0026] The controller is used to control the driver to drive the control core, so that the control core switches between the first sliding stop and the second sliding stop.

[0027] Furthermore, the first drain pipe and the guide pipe are coaxially arranged, and the end of the first drain pipe away from the diversion box is sealed by the third sealing plate.

[0028] The control core extends through the drain outlet into the first drain pipe.

[0029] The filtration mechanism also includes a second drain pipe. The second drain pipe is connected to the side wall of the first drain pipe and is located at the end of the first drain pipe near the diversion box. The side wall of the first drain pipe has a second connecting hole that communicates with the second drain pipe.

[0030] The first drain pipe is equipped with a first stop flange and a second stop flange. Both the first stop flange and the second stop flange are located on the side of the second drain pipe away from the diversion box. The first stop flange and the second stop flange are spaced apart, and the second stop flange is located on the side of the first stop flange away from the second drain pipe.

[0031] A piston is installed inside the first sewage pipe. The piston slides between the first stop flange and the second stop flange. An elastic element abuts between the piston and the third sealing plate.

[0032] The control core is also fixedly connected to a third sealing component, which is located inside the first sewage pipe and is attached to the side wall of the first sewage pipe near the second sewage pipe.

[0033] When the control core is at the first sliding stop, the second connecting hole is open. When the control core is at the second sliding stop, the third sealing element closes the second connecting hole.

[0034] Furthermore, a drive rod is fixedly connected to the side of the piston away from the diversion box. The drive rod extends axially along the first drain pipe and passes through the third sealing plate.

[0035] The filtration system also includes an air cylinder.

[0036] The drive rod is driven by the piston rod of the air cylinder. The air cylinder's inflation tube passes through the side wall of the first sewage pipe and is connected to the first sewage pipe. The inflation tube is set corresponding to the first stop flange and passes through the first stop flange.

[0037] When the piston moves toward the second stop flange, the drive rod drives the piston rod to draw air into the inflation cylinder. When the piston moves toward the first stop flange, the drive rod drives the piston rod to expel air from the inflation cylinder.

[0038] Furthermore, the drive rod has a hollow structure.

[0039] An extension rod is fixedly connected to one end face of the control core near the piston, and the extension rod extends axially along the control core. The extension rod passes through the piston and extends into the drive rod.

[0040] The diameter of the extension rod is smaller than the inner diameter of the drive rod. An end block is fixedly connected to the end of the extension rod away from the control core, and the outer diameter of the end block is larger than the diameter of the extension rod.

[0041] Along the axial direction of the control core, the extension rod slides and seals with the piston.

[0042] When the control core is at the first sliding stop, the surface of the end block near the extension rod and the surface of the second stop flange near the first stop flange are on the same plane. When the control core is at the second sliding stop, the end block is located on the side of the second stop flange near the first stop flange.

[0043] The controller is used to control the driver to drive the control core, so that the control core moves from the first sliding stop to the second sliding stop.

[0044] Furthermore, along the axial direction of the control core, in the direction from the end of the first sealing member near the second sealing member to the end away from the second sealing member, the outer diameter of the first sealing member decreases.

[0045] Along the axial direction of the control core, the outer diameter of the second sealing element decreases in the direction from the end of the second sealing element near the first sealing element to the end away from the first sealing element.

[0046] Furthermore, the diversion box is cylindrical, the diversion cavity is also cylindrical, and the diversion box, guide pipe and filter are coaxially arranged.

[0047] The beneficial effects of the technical solutions in this application include: The smart water meter based on hydropower provided in this application effectively reduces dependence on external power sources and the frequency of manual maintenance, ensuring long-term stable operation of the water meter and reducing the impact of power outages on its operation.

[0057] The technical solutions of this application will be described by way of example through some embodiments below.

[0058] See Figures 1-3 This application provides a smart water meter based on hydropower generation, which includes: a water meter body 100, a pipeline water flow power generation module 200, and an energy storage module (not shown in the figure).

[0059] Both the water meter body 100 and the pipeline water flow power generation module 200 are installed on the water supply pipeline 1000.

[0060] In this embodiment, the water meter body 100 is located downstream of the pipeline water flow power generation module 200, that is, the water outlet of the pipeline water flow power generation module 200 is connected to the water inlet of the water meter body 100. However, this is not the only possible configuration.

[0061] The power output terminal of the pipeline water flow power generation module 200 is electrically connected to the charging interface of the energy storage module. Under the action of water flow, the pipeline water flow power generation module 200 can generate electricity and charge the energy storage module according to the set output power. The energy storage module can be a lithium battery, but is not limited to this.

[0062] The power supply interface of the energy storage module is electrically connected to the water meter body 100. The electrical energy stored in the energy storage module is used to power the water meter body 100.

[0063] With this design, when water flows through the water supply pipeline 1000, the pipeline water flow power generation module 200 can generate electricity, the electricity is stored in the energy storage module, and the water meter body 100 is powered according to the preset power supply mode.

[0064] Overall, the smart water meter based on hydropower provided in this application effectively reduces dependence on external power sources and the frequency of manual maintenance, ensuring long-term stable operation of the water meter and reducing the impact of power outages on its operation.

[0065] In this embodiment, the smart water meter based on hydropower generation also includes a filtration mechanism 300.

[0066] The filter unit 300 is also installed on the water supply line 1000.

[0067] The filter mechanism 300 is located upstream of both the water meter body 100 and the pipeline water flow power generation module 200.

[0068] Specifically, the filter mechanism 300 includes: a diversion box 310, an input pipe 360, an output pipe 370, a first drain pipe 380, a control core 400, and a control module (not shown in the figure).

[0069] The diversion box 310 has a diversion cavity 311, in which a guide pipe 320 and a filter element 340 are disposed. In this embodiment, the diversion box 310 is cylindrical, the diversion cavity 311 is also cylindrical, the guide pipe 320 is cylindrical, and the filter element 340 is also cylindrical. The diversion box 310, the diversion cavity 311, the guide pipe 320, and the filter element 340 are coaxially arranged.

[0070] One end of the guide tube 320 is connected to the inner wall of one end of the diversion cavity 311. One end of the guide tube 320 is closed by the inner wall of the diversion cavity 311, and the other end of the guide tube 320 is closed by the first sealing plate 330.

[0072] The first sealing plate 330 has a first connecting hole 331 that connects the guide tube 320 and the filter element 340.

[0073] The input pipe 360 ​​and the output pipe 370 are respectively located on opposite sides of the splitter box 310. The input pipe 360 ​​passes through one side wall of the splitter box 310 and communicates with the splitter cavity 311 of the splitter box 310.

[0074] The output pipe 370 penetrates the other side wall of the shunt box 310, and the output pipe 370 extends further to the guide pipe 320. The output pipe 370 is connected to the side wall of the guide pipe 320 and communicates with the guide pipe 320.

[0075] The filter element 340 is spaced apart from the inner wall of the diversion cavity 311 at one end away from the guide pipe 320. The side wall of the diversion box 310 is provided with a drain port 312 that communicates with the diversion cavity 311. The drain port 312 is located on the side of the diversion box 310 away from the guide pipe 320.

[0076] The first drain pipe 380 is connected to the outer wall of the diversion box 310 and communicates with the drain port 312. The first drain pipe 380 and the guide pipe 320 are coaxially arranged.

[0077] The inner diameter of the filter element 340 is larger than the diameter of the first connecting hole 331, and the outer diameters of both the guide tube 320 and the filter element 340 are smaller than the inner diameter of the diversion box 310.

[0078] The control core 400 is arranged along the axial direction of the guide tube 320. The inner diameter of the guide tube 320, the diameter of the first connecting hole 331, the inner diameter of the filter element 340, the diameter of the drain port 312, and the inner diameter of the first drain pipe 380 are all larger than the diameter of the control core 400.

[0079] One end of the control core 400 penetrates the side wall of the diversion box 310 and extends outside the diversion box 310. The other end of the control core 400 is located inside the guide tube 320. The control core 400 extends into the filter element 340 through the first connecting hole 331. The control core 400 penetrates the second sealing plate 350 and extends further toward the drain outlet 312.

[0080] Along the axial direction of the guide tube 320, the control core 400 slides against the side wall of the diversion box 310 and the second sealing plate 350 and slides to seal.

[0081] The control core 400 is fixedly connected to a first sealing element 410 and a second sealing element 420. The diameter of the first sealing element 410 is smaller than the inner diameter of the filter element 340, and the diameter of the second sealing element 420 is smaller than the inner diameter of the diversion box 310.

[0082] The first sealing element 410 is located inside the filter element 340, and the second sealing element 420 is located inside the diversion cavity 311 and outside the filter element 340. The second sealing element 420 is located at the end of the filter element 340 away from the guide tube 320.

[0083] The control core 400 has a first sliding stop and a second sliding stop.

[0084] When the control core 400 is at the first sliding stop, the first sealing member 410 separates from the first sealing plate 330, the first connecting hole 331 is in the open state, the second sealing member 420 fits against the inner wall of the diversion cavity 311, and the second sealing member 420 seals the drain outlet 312.

[0085] When the control core 400 is at the second sliding stop, the first sealing member 410 is in contact with the first sealing plate 330, the first sealing member 410 closes the first connecting hole 331, the second sealing member 420 separates from the inner wall of the diversion cavity 311, and the drain port 312 is in the open state.

[0086] The control module includes: a controller (not shown in the figure) and a driver (not shown in the figure).

[0087] Both the controller and the driver are electrically connected to the power supply interface of the energy storage module, and the driver is driven by the control core 400.

[0088] The controller is used to control the driver to drive the control core 400 so that the control core 400 switches between the first sliding stop and the second sliding stop.

[0089] Furthermore, the end of the first drain pipe 380 furthest from the diversion box 310 is sealed by the third sealing plate 381. The inner diameter of the first drain pipe 380 is larger than the diameter of the drain outlet 312.

[0090] The control core 400 extends through the drain outlet 312 into the first drain pipe 380.

[0091] The filter unit 300 also includes a second drain pipe 390.

[0092] The second drain pipe 390 is connected to the side wall of the first drain pipe 380 and is located at the end of the first drain pipe 380 near the diversion box 310. The side wall of the first drain pipe 380 is provided with a second connecting hole 391 that communicates with the second drain pipe 390.

[0093] The first drain pipe 380 is provided with a first stop flange 382 and a second stop flange 383. Both the first stop flange 382 and the second stop flange 383 are located on the side of the second drain pipe 390 away from the diversion box 310, and are spaced apart. The second stop flange 383 is located on the side of the first stop flange 382 away from the second drain pipe 390. The second stop flange 383 is spaced apart from the third sealing plate 381.

[0094] A piston 384 is installed inside the first drain pipe 380, and the piston 384 is engaged between the first stop flange 382 and the second stop flange 383. Along the axial direction of the first drain pipe 380, the piston 384 is slidably engaged with the first drain pipe 380 and slides to seal.

[0095] An elastic element (not shown in the figure) abuts between the piston 384 and the third sealing plate 381, and the elastic element passes through the second stop flange 383.

[0096] The control core 400 is also fixedly connected to a third sealing member 430. The third sealing member 430 is located inside the first drain pipe 380 and on the side of the control core 400 near the second connecting hole 391. The third sealing member 430 is in contact with the side wall of the first drain pipe 380 near the second drain pipe 390.

[0097] When the control core 400 is at the first sliding stop, the second connecting hole 391 is open. When the control core 400 is at the second sliding stop, the third sealing member 430 closes the second connecting hole 391.

[0098] In this embodiment, a drive rod 385 is fixedly connected to the side of the piston 384 away from the diversion box 310. The drive rod 385 extends axially along the first drain pipe 380 and passes through the third sealing plate 381.

[0099] The filter unit 300 also includes an air cylinder (not shown in the figure).

[0100] The portion of the drive rod 385 located outside the first drain pipe 380 is in drive engagement with the piston rod 384 of the air cylinder. The air cylinder's inflation tube 386 passes through the side wall of the first drain pipe 380 and is connected to the first drain pipe 380. The inflation tube 386 is provided corresponding to and passes through the first stop flange 382.

[0101] When piston 384 moves toward the second stop flange 383, drive rod 385 drives piston rod 384 to draw in air. When piston 384 moves toward the first stop flange 382, ​​drive rod 385 drives piston rod 384 to expel air from the air cylinder, thereby allowing the air cylinder to inflate into the first drain pipe 380 through the inflation pipe 386.

[0102] Specifically, the drive rod 385 has a hollow structure.

[0103] An extension rod 440 is coaxially fixedly connected to one end face of the control core 400 near the piston 384. The extension rod 440 extends axially along the control core 400. The extension rod 440 passes through the piston 384 and extends into the drive rod 385. Along the axial direction of the control core 400, the extension rod 440 slides and seals with the piston 384.

[0104] The diameter of the extension rod 440 is smaller than the inner diameter of the drive rod 385. An end block 450 is fixedly connected to the end of the extension rod 440 away from the control core 400, and the outer diameter of the end block 450 is larger than the diameter of the extension rod 440. In this embodiment, the end block 450 is slidably fitted within the drive rod 385 along its axial direction, with a gap between the end block 450 and the inner wall of the drive rod 385 to balance the air pressure.

[0105] When the control core 400 is at the first sliding stop point, the surface of the end block 450 near the extension rod 440 and the surface of the second stop flange 383 near the first stop flange 382 are on the same plane.

[0106] When the control core 400 is at the second sliding stop, the end block 450 is located on the side of the second stop flange 383 close to the first stop flange 382.

[0107] The controller is used to control the driver to drive the control core 400 so that the control core 400 moves from the first sliding stop to the second sliding stop.

[0108] Along the axial direction of the control core 400, in the direction from the end of the first sealing member 410 near the second sealing member 420 to the end away from the second sealing member 420, the outer diameter of the first sealing member 410 decreases.

[0109] Along the axial direction of the control core 400, in the direction from the end of the second sealing member 420 near the first sealing member 410 to the end away from the first sealing member 410, the outer diameter of the second sealing member 420 decreases.

[0110] In this embodiment, the filter element 340 is made by bending a filter plate into a cylindrical shape, but is not limited thereto.

[0111] The working principle of the smart water meter based on hydropower provided in this application embodiment is as follows.

[0112] When the filter mechanism 300 is in normal working condition (i.e., in the state of performing normal filtration work), the control core 400 is located at the first sliding stop.

[0113] At this time, the first connecting hole 331 is in the open state, the drain outlet 312 is in the closed state, and the second connecting hole 391 is in the open state.

[0114] When the control core 400 is at the first sliding stop, we take the initial state as the state when the piston 384 is in contact with the first stop flange 382, ​​such as... Figure 2 As shown.

[0115] In this state, water in the water supply pipeline 1000 enters the diversion cavity 311 of the diversion box 310 through the input pipe 360. After being filtered by the filter element 340, the water in the diversion cavity 311 passes through the filter element 340 and enters the columnar space enclosed by the filter element 340. Then, it enters the guide pipe 320 through the first connecting hole 331 and finally enters the output pipe 370 from the guide pipe 320 and leaves the diversion box 310. This completes the filtration of water in the water supply pipeline 1000.

[0116] The filtered water enters the pipe water flow power generation module 200, which drives the pipe water flow power generation module 200 to generate electricity. The water flowing out of the pipe water flow power generation module 200 enters the water meter body 100 and finally flows out from the outlet of the water meter body 100.

[0117] In this state, the filtration mechanism 300 continuously filters the water, and the pipeline water flow power generation module 200 continuously generates electricity to charge the energy storage module.

[0118] After the filter mechanism 300 has been running for a period of time (the duration can be set according to the actual situation), the controller of the control module sends a command to the driver according to the preset time interval, controlling the driver to drive the control core 400, so that the control core 400 moves from the first sliding stop point to the second sliding stop point.

[0119] When the control core 400 is at the second sliding stop, the first connecting hole 331 is closed by the first sealing member 410, the drain port 312 is open, and the second connecting hole 391 is closed by the third sealing member 430. Figure 4 As shown.

[0120] At this time, the water in the diversion cavity 311 will not continue to pass through the filter element 340, and the water flow to the pipeline water flow power generation module 200 is temporarily interrupted. The water in the diversion cavity 311 directly enters the first drain pipe 380 through the drain outlet 312.

[0121] During this process, the water flow in the diversion cavity 311 can wash away the impurities filtered out by the filter element 340 from the outside of the filter element 340, and discharge these impurities into the first drain pipe 380 through the drain port 312, thereby achieving the washing of the filter element 340.

[0122] After the sewage enters the first drain pipe 380, under the action of water pressure, the sewage pushes the piston 384 to slide towards the second stop flange 383, as... Figure 5 As shown. Until the piston 384 abuts against the second stop flange 383, at this point, the surface of the piston 384 near the drive rod 385 is in contact with the surface of the second stop flange 383 near the first stop flange 382, ​​as shown. Figure 6 As shown.

[0123] When the piston 384 is about to abut against the second stop flange 383, that is, when the surface of the piston 384 near the drive rod 385 is about to come into contact with the surface of the second stop flange 383 near the first stop flange 382, ​​the surface of the piston 384 near the drive rod 385 will first come into contact with the surface of the end block 450 near the extension rod 440. This allows the piston 384 to push the end block 450 to move. In this way, the end block 450 can drive the control core 400 through the extension rod 440, thereby allowing the piston 384 to indirectly drive the control core 400 to move from the second sliding stop to the first sliding stop. When the piston 384 abuts against the second stop flange 383, the surface of the end block 450 near the extension rod 440 is in contact with the surface of the second stop flange 383 near the first stop flange 382. At this time, the surface of the end block 450 near the extension rod 440 and the surface of the second stop flange 383 near the first stop flange 382 are essentially on the same plane, and the control core 400 is driven back to the first sliding stop by the piston 384.

[0124] After the control core 400 returns to the first sliding stop, the first connecting hole 331 is in the open state, the drain port 312 is in the closed state, and the second connecting hole 391 is in the open state.

[0125] At this time, the filtration mechanism 300 can continue to filter the water, and the pipeline water flow power generation module 200 can continue to generate electricity to charge the energy storage module. At the same time, due to the opening of the second connecting hole 391, under the action of the elastic element, the piston 384 is pushed back towards the first stop flange 382, ​​and the sewage in the first drain pipe 380 is pushed from the second connecting hole 391 into the second drain pipe 390 and discharged.

[0126] The second drain pipe 390 is used to connect with the sewage pipeline to complete the sewage discharge.

[0127] Once piston 384 re-engages with the first stop flange 382, ​​the sludge discharge process is complete. At this point, the process returns to normal. Figure 2 The state shown.

[0128] It is important to note that during the movement of piston 384 towards the second stop flange 383 (when sewage enters the first drain pipe 380), drive rod 385 drives air pump to draw in air. When piston 384 moves back towards the first stop flange 382 (when sewage is discharged into the second drain pipe 390), drive rod 385 drives air pump to inflate the first drain pipe 380 through air pump 386. This allows the air bubbles to thoroughly agitate impurities within the first drain pipe 380, promoting their discharge into the second drain pipe 390 along with the water flow. This minimizes the residue and deposition of impurities within the first drain pipe 380, achieving self-cleaning of the first drain pipe 380.

[0129] Then, repeating the above steps will achieve repeated self-cleaning, so I will not go into details.

[0130] The beneficial effects of the smart water meter based on hydropower provided in this application include, but are not limited to, the following:

[0131] This effectively reduces dependence on external power sources and the frequency of manual maintenance, ensuring long-term stable operation of the water meter and minimizing the impact of power outages on its operation.

[0132] It can achieve self-cleaning of its own filtration mechanism 300.

[0133] When the filter mechanism 300 is self-cleaning, the control core 400 only needs to be driven once by the driver. That is, the control core 400 only needs to be driven from the first sliding stop point to the second sliding stop point to automatically complete the self-cleaning and reset of the control core 400, which saves more power and can reserve more power for the meter body.

[0134] When the driver drives the control core 400, that is, after the driver drives the control core 400 from the first sliding stop to the second sliding stop, even if the power in the energy storage module is insufficient, the control core 400 can automatically reset using the water pressure in the water supply pipeline 1000, so as to continue to generate electricity normally using the pipeline water flow power generation module 200. This will not cause too much water to enter the sewage pipe, thus avoiding the waste of water resources and realizing the automatic reset of the control core 400 in the absence of power.

[0135] The distance between the first stop flange 382 and the second stop flange 383 determines the movable distance of the piston 384 during self-cleaning, thereby controlling the amount of water consumed in each self-cleaning, facilitating precise control of flushing water use, and saving water resources.

[0136] It can effectively reduce the residue and deposition of impurities in the first drain pipe 380.

[0137] In summary, the smart water meter based on hydropower provided in this application effectively reduces dependence on external power sources and the frequency of manual maintenance, ensuring long-term stable operation of the water meter and reducing the impact of power outages on its operation.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
