Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference example Figures 1 to 4 A self-powered 4G communication water meter comprises a water meter body 1, a lithium battery 2 and a circuit board 3 are arranged in the water meter body 1, a charging module of the circuit board 3 is electrically connected to the lithium battery 2, a power supply assembly 4 is arranged at the output end of the water meter body 1, the power supply assembly 4 comprises a tube body 5, a generator 6, an impeller 7, a shell 8, and a cover plate 9, a cavity 51 is arranged in the tube body 5, the impeller 7 is arranged in the cavity 51, the shell 8 is detachably connected and fixed to the tube body 5, the generator 6 is installed in the shell 8 and is on the same center line as the impeller 7, the generator 6 is also electrically connected to the circuit board 3, and the cover plate 9 is fixedly installed on the end surface of the cavity 51 to prevent the generator 6 from directly contacting the impeller 7; the impeller 7 transmits power to the generator 6 via non-contact mode, so that the rotating shaft of the generator 6 rotates;

[0028] It is worth mentioning that both the input end and the output end of the water meter body 1 are provided with an external thread groove 11, and the external thread is used in conjunction with the first internal thread groove 52;

[0029] It is worth mentioning that the input end and the output end of the tube body 5 are both provided with a first internal thread groove 52, and are engaged with the external thread groove 11. Since the power supply component 4 is an independent device, it is convenient to connect or disassemble with the water meter body 1 through the first internal thread groove 52, and can be installed on a 4G communication water meter with a lithium battery 2. Only the circuit board 3 needs to be replaced, which greatly improves the applicability and practicality.

[0030] It is worth mentioning that the tube body 5 is provided with a threaded column 53, a roller 54 is provided inside the threaded column 53, a through hole 55 is provided at the bottom of the threaded column 53, and a positioning hole 56 is provided at the bottom of the cavity 51. The threaded column 53 is used in conjunction with the housing 8, the roller 54 reduces the resistance to the rotation of the impeller 7, the through hole 55 is used in conjunction with the transmission shaft 71, and the positioning hole 56 is used in conjunction with the positioning shaft 72;

[0031] It is worth mentioning that a transmission shaft 71 and a positioning shaft 72 are respectively provided at both ends of the impeller 7. The positioning shaft 72 is inserted into the positioning hole 56. The transmission shaft 71 passes through the through hole 55 and the roller 54. An O-ring 57 is provided between the inner ring of the through hole 55 and the roller 54 and the transmission shaft 71. A first magnetic wheel 73 is provided on the end surface of the transmission shaft 71. The power of the impeller 7 is transmitted to the first magnetic wheel 73 through the transmission shaft 71. The positioning shaft 72 rotates with the positioning hole 56 as the axis. The O-ring 57 prevents the water flow passing through the cavity 51 from entering the threaded column 53. This is the first sealing device.

[0032] It is worth mentioning that the cover plate 9 is fixed to the end face of the threaded column 53 by screws, and the cover plate 9 is provided with an annular protrusion 91, and abuts against the inner wall of the threaded column 53. The cover plate 9 is made of plastic, and its annular protrusion 91 is embedded in the threaded column 53 by interference fit, and abuts against the inner wall of the threaded column 53. The labyrinth seal structure prevents water vapor or water from flowing out and directly contacting the generator 6, causing the coil inside the generator 6 to be damaged due to short circuit, thereby extending the service life of the generator 6;

[0033] It is worth mentioning that the inner wall of the housing 8 is provided with a second internal thread groove 81, which is engaged with the threaded column 53. When the generator 6 fails or is damaged, the second internal thread groove 81 facilitates the removal or installation of the housing 8 from the threaded column 53, and at the same time, facilitates the assembly of the production line;

[0034] It is worth mentioning that the shaft end face of the generator 6 is provided with a second magnetic wheel 61, and the magnetic poles of the first magnetic wheel 73 are attracted by the same polarity. The first magnetic wheel 73 and the second magnetic wheel 61 utilize the magnetic properties of the same polarity to attract each other and the opposite polarity to repel each other, and convert the repulsion into a driving force. In a static state, the S and N poles between the first magnetic wheel 73 and the second magnetic wheel 61 correspond to each other. When the first magnetic wheel 73 rotates, the magnetic pole position changes. The adjacent opposite polarity magnetic poles are utilized to push the second magnetic wheel 61 to rotate, thereby realizing non-contact magnetic transmission of power.

[0035] It is worth mentioning that the detachable setting is the second internal thread groove 81, and the non-contact power transmission is set to the first magnetic wheel 73 and the second magnetic wheel 61. The non-contact power transmission blocks the impeller 7 from directly contacting the generator 6, preventing the generator 6 from being damaged by water vapor or seepage, thereby extending the service life of the generator 6.

[0036] The use principle of the utility model is now described as follows:

[0037] When water flows through the output end of the water meter body 1, enters the input end of the tube body 5, and continues to pass through the cavity 51, driving the impeller 7 to rotate, and the roller 54 reduces the resistance to the rotation of the impeller 7. At this time, the first magnetic wheel 73 rotates, and the second magnetic wheel 61 rotates synchronously through magnetism, so that the magnetic field on the rotor of the generator 6 and the coil on the stator produce relative motion, which drives the charge to flow in the wire, forming an electric current, and transmits it to the circuit board 3. Since the generator 6 produces alternating current, the charging module on the circuit board 3 (because it is a prior art, it will not be repeated here) converts the alternating current into a stabilized direct current and continuously supplies power to the lithium battery 2, ensuring that the service life of the lithium battery 2 is extended in a low temperature environment and during normal operation, thereby reducing the maintenance workload.

[0038] The above design scheme can make the product have the advantages of long service life, high practicality and reduced maintenance frequency.

[0039] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
