[0014] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0016] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inside", "outside", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] See also Figure 1-5 As shown, an electromagnetic water meter with the function of cleaning surface attachments includes a measurement and control box body 1, a ring-carrying block 3, an electrode module 4, an electromagnetic module 5, a connection type cover 6, a rubber-plastic hard core tube 7, a U-shaped support rod 8, a scraper block 9, a fan-shaped cover 10, a motor 11, a bearing 12 and a driving gear 13. The measurement and control box body 1 is fixedly connected to the corresponding part of the ring-carrying block 3 through a flange pipe seat 2, and a group of electrode modules 4 and electromagnetic modules 5 are respectively arranged at two symmetrical positions of the ring-carrying block 3; The middle part of the rubber-plastic hard core tube 7 is located in the middle position of the ring hole of the ring carrier block 3, and U-shaped struts 8 are distributed in the rubber-plastic hard core tube 7. The scraper block 9 located in the middle of each U-shaped strut 8 is in contact with the inner wall of the rubber-plastic hard core tube 7. The cross-sectional specifications of the scraper block 9 and the U-shaped strut 8 are small. At the same time, the scraper block 9 and the U-shaped strut 8 are parallel to the flow direction of the liquid, and the measurement impact is small and can be ignored. The rubber-plastic hard core tube 7 is symmetrically provided with integrated gear rings 702, and one of the integrated gear rings 702 is meshed and connected with the driving gear 13. One side shaft end of the driving gear 13 is connected to the shaft end of the motor 11. The inner sides of the outward rolled ends 701 located at both ends of the rubber-plastic hard core tube 7 are respectively rotatably sealed with the corresponding structures in the ports of one end of the two connecting covers 6 through bearings 12, and the other end of the connecting cover 6 is threadedly connected to the internal threaded ring groove 301 on the same side.

[0018] Combination Figure 1 and Figure 2As shown, the driving gear 13 is located in the fan-shaped cover 10, and the cover opening of the fan-shaped cover 10 is connected to the interior of one of the connecting covers 6, and the side wall of one side of the fan-shaped cover 10 is fixedly connected to the end part of the motor 11 to install the driving gear 13 and the motor 11.

[0019] like Figure 1 A slot 601 is distributed on the annular wall of one end of the connection cover 6, and the corresponding end portion of the inherent U-shaped support rod 8 is inserted into the slot 601 to play the role of installing and fixing the U-shaped support rod 8.

[0020] The inner wall of the rubber-plastic hard core tube 7 is a high-strength porcelain surface, the tube body thickness between the two ends of the rubber-plastic hard core tube 7 is 1 mm, and the wall thickness of the outward rolled end portions 701 located at the two ends of the rubber-plastic hard core tube 7 is 5 mm. By setting the tube body thickness between the two ends of the rubber-plastic hard core tube 7 to 1 mm, the influence of test factors such as electromagnetic magnetic fields is greatly reduced.

[0021] Furthermore, a converter, a controller and a flow detection module are provided inside the measurement and control box body 1.

[0022] Furthermore, wiring channels are distributed inside the structure of the ring carrier block 3.

[0023] When the present invention is in use, when the fluid is in a non-flowing state during a set time period, the rubber-plastic hard core tube 7 connected by the driving gear 13 and the integrated gear ring 702 is driven to rotate by the running motor 11, and the corresponding surface of the stationary and fixed scraper block 9 contacts the inner wall of the rubber-plastic hard core tube 7, so as to scrape off the impurities attached to the inner wall of the rubber-plastic hard core tube 7, prevent the thick layer of attachments from affecting the measurement accuracy, avoid the accumulation and blockage of attachments, solve the problem of inconvenient cleaning of the water flow test channel surface of the existing electromagnetic water meter, and at the same time adopt a non-contact method between the surface of the rubber-plastic hard core tube 7 and the ring hole in the middle of the ring carrier block 3, replacing the structural form of the solidified structure layer, which not only ensures the independent rotation of the rubber-plastic hard core tube 7, but also facilitates disassembly and replacement.
