Description

Technical Field

[0001] The invention relates to the technical field of tap water meters, in particular to a wireless tap water meter. Background Art

[0002] With the advancement of technology, water meters with wireless data transmission are gradually replacing conventional water meters that require regular on-site meter reading. Water meters with wireless data transmission can save data such as water consumption and water frequency and transmit them to users and managers at regular intervals. However, there are also some shortcomings in the process of use: 1. The existing water meter rotates the internal blades under the impact of water flow, driving the mechanical gear transmission to record the water consumption. However, the water flow inside the existing pipeline cannot be guaranteed to be stable. The value cannot be effectively monitored when the flow rate is small. When the flow rate is high, it is easy to cause excessive wear of the internal components. A regulating valve needs to be installed for use, which increases the cost of pipeline installation; 2. Existing wireless water meters are powered by batteries, but the batteries have a limited service life and require personnel to replace the batteries regularly, which is inconvenient to use; 3. In order to prevent the existing water meters from freezing in winter, insulation layers are installed on the sides and heated with heating networks. The antifreeze effect is poor and energy consumption is further increased. In addition, some traditional old water meters require a one-time high transformation cost to replace them with wireless water meters, which limits their large-scale promotion. For this reason, we propose a wireless tap water meter. Summary of the invention

[0012] Compared with the prior art, the present invention can achieve the following beneficial effects: 1. The present invention provides an adjustment component and a drive component, so that each component is easy to disassemble and install, and subsequent maintenance and use are more convenient. The water flow entering the core frame can be adapted and adjusted, so that the data for monitoring water consumption is more accurate and will not be affected by the water flow rate.

[0014] 3. The present invention sets an auxiliary component, and the linkage rod drives the magnet rotor frame to rotate to cooperate with the coil block to perform electromagnetic cutting and power generation operations. The current is converted to the battery inside the instrument panel through the circuit board to store electricity. When the coil block generates an electromagnetic field, the heat conductive sheet can be heated. The heat conductive sheet introduces heat into the water flow on the side of the core frame to heat the water, so that the water inside the water meter will not freeze, and the temperature of the water flow can be increased, reducing the energy consumption generated by subsequent household heating of the water flow.

[0015] 4. The present invention provides a driving component and an auxiliary component, so that the fan blade block will impact and squeeze the movable rod, so that the movable rod elastically impacts the side of the heat conducting plate to vibrate, so that the movable rod can dissipate heat into the water flow more quickly, and the movable rod drives the water flow to vibrate, which can further prevent the freezing of the water body; The linkage rod can be used to drive the magnet rotor frame to move up and down between the mounting frame and the sealing plate, so that the staggered position of the magnet rotor frame and the coil block can be adjusted to control the electromagnetic cutting efficiency of the magnet rotor frame and the coil block, thereby adjusting the power generation and the temperature control of the heating of the heat conducting plate.

[0016] 5. The present invention sets a movable block. When the movable block is driven to rotate by the friction of the slider, the angle sensor of the movable block can determine the positions of the first adjustment plate and the second adjustment plate. In this way, the positions can be fed back to the internal control module of the instrument panel, so that the first adjustment plate and the second adjustment plate can adjust the water flow more accurately; and the movable block constrains the driving cylinder so that it can stably rotate inside the core frame.

[0017] 6. The present invention can constrain the linkage rod by setting the mounting block, and perform a certain sealing operation on the side of the linkage rod, thereby reducing the flow of water into the interior of the mounting frame and affecting the circuit board and the coil block.

[0018] 7. The present invention modularizes the components, and most of the components are installed by threads, so that the components are easy to replace and maintain in the future, and are compatible with the external shell of the old water meter. It is also convenient to modify the old water meter by replacing the internal core assembly components. BRIEF DESCRIPTION OF THE DRAWINGS

The fixed block 41 is a circular ring block with a spline shape on the inside. An electric push rod 411 is fixedly installed inside the fixed block 41 and is arranged at the lower side of the core frame 31. The electric push rod 411 is connected to the control module and the battery inside the instrument panel 11 through a circuit. The electric push rod 411 is an electric telescopic rod with a nut block installed inside the output end. The upper side of the electric push rod 411 corresponds to the inner position of the core frame 31. A driving cylinder 42 is provided and the driving cylinder 42 is movably mounted on the inner side of the movable block 341. The driving cylinder 42 is a cylindrical cylinder. Mounting blocks 421 are fixedly mounted on both sides of the driving cylinder 42. The mounting blocks 421 are circular ring blocks made of rubber. A sliding groove 43 is evenly spaced in a circular array on the side of the driving cylinder 42 corresponding to the position of the movable block 341. The sliding groove 43 is a rectangular groove. A slider 431 is movably mounted inside the sliding groove 43. The slider 431 is partially movably sleeved on the side of the driving cylinder 42. The first support cylinder 422 is a bellows-shaped cylinder made of spring steel. A linkage rod 44 is movably arranged inside the driving cylinder 42 and the mounting block 421. The linkage rod 44 penetrates the core frame 31, the mounting frame 32 and the sealing member 31. The sealing plate 33 is connected to the inside of the instrument panel 11, and the linkage rod 44 is threadedly installed with the slider 431 and the internal nut of the output end of the fixed block 41 respectively.

The driving gear 46 is splined on the upper side of the linkage rod 44, and the driving gear 46 is arranged inside the instrument panel 11 and meshes with its internal mechanical gear;Specifically, the drive cylinder 42 is constrained by the core frame 31 drive assembly 4 so that the water flow impacts the fan blade block 45 to drive the drive cylinder 42 to rotate. When the drive cylinder 42 rotates, it can drive the linkage rod 44 to rotate through the slider 431. The linkage rod 44 drives the driving gear 46 to rotate and mesh with the mechanical gear inside the instrument panel 11, driving the instrument panel 11 to read the water consumption value. When the synchronous linkage rod 44 rotates, it can be guided by the internal nut at the output end of the electric push rod 411 to avoid interference. The electric push rod 411 can push the linkage rod 44 to rotate inside the drive cylinder 42. The linkage rod 44 moves up and down, so that the slider 431 slides inside the slide groove 43, so that the upper and lower sides can fit on the side of the corresponding movable block 341 for friction, and the movable block 341 at the corresponding position is driven to rotate and drive the first adjustment plate 342 or the second adjustment plate 343 to rotate and cooperate with the first water inlet groove 312, the second water inlet groove 313 and the first water inlet groove 312 to adjust the water inlet and outlet. The first support tube 422 is provided to ensure that the slider 431 can move and constrain it at the same time, so that the linkage rod 44 can be more conveniently threadedly installed or disassembled inside it; The auxiliary component 5 can be used to perform auxiliary power generation and internal heating of the water meter when monitoring the water consumption, and the power generation efficiency can be adjusted according to demand; like Figure 3 , Figure 4 and Figures 9 to 11As shown, the auxiliary component 5 includes a magnet rotor frame 51 which is splined on the side of the linkage rod 44 and the magnet rotor frame 51 is arranged between the mounting frame 32 and the sealing plate 33. The linkage rod 44 serves as a limiting support for the magnet rotor frame 51. The magnet rotor frame 51 is a circular frame with magnets arranged on the side with equidistant and staggered magnetic poles. On the upper side of the mounting frame 32, corresponding to the position of the magnet rotor frame 51, a coil block 52 is arranged in a circular array in an equidistant manner. The coil block 52 is an electromagnetic induction coil. A circuit board 521 is clamped on the upper side of the mounting frame 32 and the coil block 52 is fixedly installed on the upper side of the circuit board 521. The circuit board 521 can convert the current generated by the coil block 52 and supply it to At the battery inside the instrument panel 11, an installation cavity 53 is equidistantly opened on the side of the installation frame 32 corresponding to the position of the coil block 52, and the installation cavity 53 passes through the side of the core frame 31. A heat conductive sheet 531 is clamped and installed inside the installation cavity 53, and the heat conductive sheet 531 is set at the internal position of the coil block 52 and extends to the side position of the core frame 31. The heat conductive sheet 531 is an "L"-shaped sheet made of a metal material that is easy to conduct heat. On the side of the core frame 31, corresponding to the position of the heat conductive sheet 531, an active groove 54 is equidistantly opened and passes through it. The active groove 54 is a cylindrical groove with a cross-shaped cross-section. An active rod 541 is movably installed inside the active groove 54, and the active rod 541 extends to the core frame 3 1 inside and outside positions, the movable rod 541 is a "T"-shaped cylindrical rod with a convex side, a second support cylinder 542 is fixedly connected between the side of the movable rod 541 and the inner wall of the movable groove 54, and the second support cylinder 542 is movably sleeved on the side of the movable rod 541, and the second support cylinder 542 is a bellows-shaped cylinder made of spring steel; specifically, when the linkage rod 44 rotates, it can drive the magnet rotor frame 51 to rotate, and perform electromagnetic cutting with the coil block 52, so that the coil block 52 performs power generation operation, and guides the current to the internal battery of the instrument panel 11 through the circuit board 521 for power storage, and the lifting of the linkage rod 44 can drive the magnet rotor frame 51 to move accordingly , so that the electromagnetic cutting efficiency of the side of the coil block 52 by the magnet rotor frame 51 can be changed to adjust the power generation efficiency. In addition, the heat conductive sheet 531 is arranged inside the coil block 52. When the coil block 52 generates power to generate a magnetic field, the heat conductive sheet 531 can be heated, so that the heat conductive sheet 531 can guide heat to the side of the core frame 31 to heat the water flow and prevent the water inside the water meter from freezing. When the fan blade block 45 rotates with the driving cylinder 42, the fan blade block 45 will be squeezed on the side of the movable rod 541 and slide and impact on the side of the heat conductive sheet 531, causing the heat conductive sheet 531 to vibrate, further reducing the possibility of water freezing, and improving the efficiency of heat dissipation of the heat conductive sheet 531 in the water flow.

[0023] Working principle: During normal use: water flows in the meter body 1, and water flows in from the flow sensor 2. The flow sensor 2 monitors the flow rate of the water flow. Water flows in from the first water inlet groove 312 and the second water inlet groove 313 at the bottom of the core frame 31, and the impact blade block 45 drives the driving cylinder 42 to rotate. The synchronous linkage rod 44 rotates accordingly under the constraint of the slider 431. The linkage rod 44 drives the driving gear 46 to engage and drive with the mechanical gear inside the instrument panel 11, so that the instrument panel 11 monitors the water consumption value, and then wirelessly feeds back to the external general control for recording; When using electricity storage: when the linkage rod 44 rotates, it drives the magnet rotor frame 51 to rotate, and the magnet rotor frame 51 and the coil block 52 perform electromagnetic cutting and power generation operations, and the current is converted to the battery inside the instrument panel 11 through the circuit board 521 to store electricity, and when the coil block 52 generates an electromagnetic field, the heat conductive sheet 531 can be heated, and the heat conductive sheet 531 itself conducts heat to the side of the core frame 31 to heat the water flow, so that the water inside the water meter will not freeze, and the temperature of the water flow can be increased, reducing the energy consumption generated by subsequent household heating of the water flow; When the fan blade block 45 rotates, the fan blade block 45 will impact and squeeze the side of the movable rod 541, so that the movable rod 541 elastically impacts the side of the heat conducting sheet 531 to vibrate, so that the movable rod 541 can dissipate heat into the water flow more quickly, and the movable rod 541 drives the water flow to vibrate, which can further prevent the water body from freezing. In addition, according to the external temperature and the remaining battery power inside the instrument panel 11, the linkage rod 44 can be driven by the electric push rod 411 to perform lifting operations, ensuring that the slider 431 slides accordingly and does not touch the side position of the movable block 341. The linkage rod 44 can drive the magnet rotor frame 51 to move up and down between the mounting frame 32 and the inside of the sealing plate 33, so that the staggered position of the magnet rotor frame 51 and the coil block 52 can be adjusted to control the electromagnetic cutting efficiency of the magnet rotor frame 51 and the coil block 52, thereby adjusting the power generation and the temperature control of the heating of the heat conducting sheet 531; When the water flow needs to be adjusted, the electric push rod 411 can be used to drive the linkage rod 44 to move up and down, so that the upper and lower position sliders 431 can be rubbed to the side position of the movable block 341, and the water flow in and out of the core frame 31 can be adjusted; When the upper slider 431 contacts the movable block 341, the movable block 341 drives the second adjustment plate 343 to rotate and cooperate with the water outlet trough 311 to adjust the staggered position, and the rotation position of the second adjustment plate 343 can be obtained through the angle sensor on the side of the movable block 341, so that the water flow out of the core frame 31 can be adjusted to ensure stable water supply to the user; When the lower slider 431 contacts the movable block 341, the movable block 341 drives the first adjustment plate 342 to rotate and cooperate with the first water inlet groove 312 and the second water inlet groove 313 to adjust the staggered position. Similarly, the rotation position of the first adjustment plate 342 is obtained through the side angle sensor of the movable block 341. In this way, the water flow into the core frame 31 can be adjusted, so that the fan blade block 45 is subjected to the impact force to ensure a uniform speed, thereby ensuring the accuracy of the water consumption monitoring data.

[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
