Description

Technical Field

[0001] This utility model relates to the field of smart water meter technology, and in particular to a detachable Internet of Things wireless remote transmission water meter. Background Technology

[0002] With the development of the times, smart technology has continuously entered people's lives. The original water meters have evolved from simply observing the surface data to smart water meters that transmit data remotely through Internet of Things technology, allowing people to directly observe water volume data through their mobile phones. Consequently, users no longer need to directly observe the water meter. Therefore, during daily renovations, water meters are often installed in remote, small corners or hidden in cabinets. When remote communication fails, users still need to check the water volume by observing the surface data. However, in small spaces or cabinets, it is difficult for users to directly observe the specific data, and maintenance of the water meter is also difficult. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a detachable IoT wireless remote water meter. By setting a fixed base and a detachable movable housing, when the water meter is installed in a relatively narrow place, the user can directly remove the movable housing with the counting display function from the base, hold the meter to read it, and after reading, the magnetic adsorption strip set on the fixed base cooperates with the metal strip at the bottom of the housing to fix the position of the movable housing. When the user needs to replace the battery or repair the housing, it is not necessary to remove the entire valve body. Only the housing part needs to be removed to replace the internal battery or perform maintenance. The whole process is simple and convenient.

[0005] This utility model provides a detachable IoT wireless remote water meter, including a flow valve with a fixed base extending upward, an impeller disposed in the flow valve, a transmission component connected to the impeller and disposed in the fixed base, and a movable housing magnetically connected to the fixed base.

[0006] The fixed base has two opposing magnetic adsorption strips attached to its surface. The bottom of the movable box is provided with a base plate, and a slot is opened on the side of the base plate corresponding to the fixed base. A metal strip is placed in the slot, and the magnetic adsorption strip and the metal strip are attracted to each other. A measuring hole is opened on the surface of the fixed base, and the measuring hole is located inside the two magnetic adsorption strips. The inner cavity of the fixed base is connected to the outside through the measuring hole. A Hall effect tachometer is provided extending downward from the movable box. The end of the Hall effect tachometer passes through the measuring hole and is located inside the fixed base.

[0007] The flow valve is designed to connect with pipes on both sides to fix the position of the water meter. An upward-extending fixed base connects with the movable housing. A magnetic strip on the fixed base attracts a metal strip in a groove at the bottom of the movable housing, allowing the housing to be detached. When the water meter is installed in a confined space where direct observation is inconvenient, the movable housing can be removed for direct observation. The impeller in the flow valve is driven by the water flow to rotate, causing the transmission component to rotate. A Hall effect tachometer located on the side of the transmission component measures the rotation speed, thus counting the water volume and transmitting it to the movable housing. The movable housing then displays the water volume data to the user via wireless remote transmission through the Internet of Things (IoT), allowing the user to view the current water volume on a mobile device.

[0008] In some embodiments, the transmission assembly includes a drive gear and a bipolar magnetic gear. The drive gear is disposed on the top of the impeller and is rotatably connected to the inner cavity of the fixed base. The bipolar magnetic gear is also rotatably disposed in the inner cavity of the fixed base and meshes with the drive gear. When the impeller starts to rotate under the drive of water flow, the drive gear located above it is driven along with it, and the bipolar magnetic gear meshing with it also rotates.

[0009] In some embodiments, the upper surface of the bipolar magnetic gear is provided with N-pole and S-pole magnets facing each other. One side of the bipolar magnetic gear meshes with the drive gear, and the other side of the bipolar magnetic gear is located below the measuring hole. During rotation, the N-pole and S-pole of the magnets continuously switch. The threaded fixing rod is located on the side of the bipolar magnetic gear and senses the switching N-pole and S-pole, thereby realizing water volume counting.

[0010] In some embodiments, the movable housing further includes a control circuit board and a top cover. The top cover and the bottom plate are fastened together to form a receiving cavity, and the control circuit board is fitted inside the receiving cavity. The receiving cavity formed by the fastening of the top cover and the bottom plate is used to house the control circuit board, which realizes intelligent control of the entire water meter and remotely transmits the water meter data to the Internet of Things. The specific connection method of the top cover and the bottom plate can be fastening or bonding. The specific structure for fastening can refer to the prior art, and will not be elaborated here.

[0011] In some embodiments, a bottom hole is provided on the base plate, the position of which is offset from the position of the measuring hole. The Hall effect tachometer includes an integrally connected threaded fixing rod and a control end. The control end is located within the receiving cavity. The end of the threaded fixing rod passes through the bottom hole and the measuring hole and is located on the side of the bipolar magnetic gear. The bottom hole allows the Hall effect tachometer to extend from the movable housing into the measuring hole. The position of the bottom hole and the measuring hole can be opposite or offset, allowing the end of the threaded fixing rod to be flexibly inserted. The threaded fixing rod is the sensing end of the Hall effect tachometer, and the control end is used to collect data and is electrically connected to the control circuit board.

[0012] In some embodiments, two fixing nuts are screwed onto the threaded fixing rod. Nut grooves are correspondingly provided on the upper and lower sides of the bottom hole, and the fixing nuts are screwed onto the upper and lower sides of the bottom hole and located in the nut grooves. The fixing nuts are used to fix the position of the threaded fixing rod, keeping the Hall tachometer in a vertical state, thereby detecting the switching of the N pole and S pole on the bipolar magnetic gear.

[0013] In some embodiments, the control circuit board is provided with a control chip, a wireless communication module, and a protective post. The protective post is positioned corresponding to the Hall effect tachometer, extending vertically and surrounding the control terminal. The Hall effect tachometer is electrically connected to the control chip. The control chip, in conjunction with the wireless communication module, enables remote data transmission via the Internet of Things. The specific chip configuration and code are familiar to those skilled in the art and can be found in existing technologies. The vertically positioned protective post protects the internal control terminal, keeping it in a vertical position.

[0014] In some embodiments, the movable housing further includes a power supply battery assembly located on the control circuit board. The power supply battery assembly includes a battery base and a removable battery, which is secured to the battery base and electrically connected to the control circuit board. The power supply battery assembly, electrically connected to the control circuit board, provides power to it. When the user needs to replace the battery or perform maintenance on the housing, it is not necessary to remove the entire valve body; only the housing portion needs to be removed to replace the internal battery or perform maintenance. The specific structure of the power supply battery assembly can be found in existing technologies.

[0015] In some embodiments, the top cover is further provided with a display screen and a flip cover. The flip cover is rotatably connected to the surface of the top cover and corresponds to the position of the display screen. The display screen is electrically connected to the control circuit board. The display screen is used by the user to observe the water flow count, the flip cover is used to protect the display screen, and the control circuit board is electrically connected to the display screen to transmit the detected data to the display screen.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are:

[0017] This utility model, by setting a fixed base and a detachable movable housing, allows the user to directly remove the movable housing with counting display function from the base when the water meter is installed in a relatively narrow place. The user can then hold the meter to read the reading. After reading the reading, the movable housing is fixed in place by the magnetic adsorption strip on the fixed base engaging with the metal strip at the bottom of the housing. When the user needs to replace the battery or perform maintenance on the housing, it is not necessary to remove the entire valve body. Only the housing part needs to be removed to replace the internal battery or perform maintenance. The whole process is simple and convenient.

[0018] The movable housing of this utility model is provided with a Hall effect tachometer, which is used to measure the rotation speed of the bipolar magnetic gear in the fixed base, thereby measuring the water volume. After the movable housing is attracted to the fixed base, the Hall effect tachometer is accurately inserted into the fixed base and located on the side of the bipolar magnetic gear. When disassembly is required, the Hall effect tachometer can be pulled out directly.
