Detailed Description
The invention will now be further described with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, the embodiment of the invention discloses a multi-flow water meter metering mechanism for regulating water flow, which includes a multi-flow water meter body 1A, where the multi-flow water meter body 1A includes a housing 11A, the housing 11A is provided with a water inlet channel 12A and a water outlet channel, the multi-flow water meter body 1A is located in the water inlet channel 12A and is provided with a first filter screen 1, a rotating shaft 31 is arranged in the water inlet end direction of the first filter screen 1, the rotating shaft 31 is fixedly provided with three scraping plates 2, the scraping plates 2 are attached to the first filter screen 1, the multi-flow water meter body 1A is located in the water inlet channel 12A and is rotatably provided with an impeller 3, and the impeller 3 and the rotating shaft 31 are driven by a transmission gear set. The water flows through the impeller 3 to drive the impeller 3 to rotate, and the impeller 3 drives the rotating shaft 31 to rotate so as to drive the scraping plate 2 to scrape off impurities on the first filter screen 1.
In order to conveniently remove impurities, a recovery box 6 is arranged on the multi-flow water meter body 1A, the recovery box 6 is arranged below the scraping plate 2 and is communicated with a water inlet channel 12A at the front end of the first filter screen 1, a second filter screen 62 is arranged at the water outlet end of the recovery box 6, the recovery box 6 is communicated with a water inlet channel 12A at the rear end of the first filter screen 1 through a connecting pipe 7,
in order to avoid the impurities remaining on the scraping plate 2, an elastic scraping plate 4 is fixedly arranged on the multi-flow water meter body 1A, the elastic scraping plate 4 is arranged on a rotation path of the scraping plate 2, when the scraping plate 2 rotates to pass through the scraping plate 2, the scraping plate 2 on the scraping plate can be scraped by the scraping plate and acts on water flow to flow into the recovery box 6, the recovery box 6 comprises a box body 63 and a cover plate 61 capable of being opened and closed, and when the impurities are deposited to a certain degree, the cover plate 61 can be opened to remove the impurities in the recovery box 6.
