Description

Technical Field

[0001] The utility model relates to the technical field of water meter connectors, and more specifically, to a water meter pipe connector for power generation. Background Art

[0002] At present, the existing pipe connectors between water meters and water pipes generally only have a simple connection function. With the popularization of smart water meters, water meters need to be powered when in operation. Conventional power supply methods use battery power supply and direct power supply. The above power supply cannot generate electricity through water flow, cannot fully utilize the water flow, and does not have the characteristics of energy saving and emission reduction.

[0003] Patent announcement number CN216348915U discloses a water meter with a power generation function. Water flows into the water meter housing through the water inlet pipe, which can cause the impeller to rotate clockwise. The water flows out of the outlet pipe through the upper through hole. At the same time, the impeller starts to rotate, and the impeller drives the rotating shaft to rotate through the bearing seat, and the rotating shaft drives the DC generator to rotate.

[0004] The above-mentioned power generation structure is installed on the water meter, which occupies a large space and is not conducive to installation. At the same time, the overall structure of the water meter needs to be improved, which is costly and not convenient for disassembly and installation. Utility Model Content

[0005] The purpose of the utility model is to provide a water meter pipe connector for power generation which has a simple structure and is easy to install and disassemble.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a water meter pipe connector for power generation, including an external sleeve and an external sleeve, and also including an internal pipe, a winding group, a permanent magnet tube and a power generation impeller. One end of the external sleeve is provided with an external threaded joint of an integrated structure, and the other end of the external sleeve is open. The internal pipe is threaded and installed in the external sleeve. The end of the internal pipe away from the external sleeve is provided with a second external threaded joint. The external sleeve is connected to the second external threaded joint. The winding group is located outside the internal pipe, the permanent magnet tube is rotatably installed in the internal pipe, and the power generation impeller is fixedly installed in the permanent magnet tube.

[0007] Preferably, an annular groove is provided on the inner wall of the external sleeve, a bearing is fixedly installed in the annular groove, and the inner ring of the bearing is fixedly connected to the permanent magnet tube.

[0008] Preferably, an annular cavity is formed between the inner tube and the outer sleeve, and the winding group is installed in the annular cavity.

[0009] Preferably, the winding set is made of copper wire.

[0010] Preferably, the connections between the external sleeve, the internal pipe and the external sleeve are all sealed by rubber rings.

[0011] Preferably, the inner ring of the bearing and the permanent magnet tube are fixedly connected via a pull plate.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] The utility model can generate electricity without modifying the water meter, thereby reducing production costs. It can be installed according to needs. When water enters the external sleeve, the water flow will impact the power generation impeller, thereby driving the permanent magnet tube to rotate. The magnetic field of the permanent magnet tube will rotate and cut the winding group to generate current.

[0014] The water meter pipe connector can be installed between the water meter and the water supply pipe. It has a small structure, which can effectively reduce the occupied space and facilitate installation and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
