Horizontal spiral wing type detachable water meter impeller protection equipment

Abstract

The invention belongs to the technical field of protection devices, and particularly relates to horizontal spiral wing type detachable water meter impeller protection equipment which comprises a box body internally provided with a cavity, a water inlet pipe and a water outlet pipe are embedded in the top and the bottom of the box body correspondingly, and sliding grooves are formed in the left portion and the right portion of the inner wall of the box body correspondingly. A sliding block is slidably connected to the inner wall of each sliding groove, a vertical rod is fixedly connected to the side, away from the corresponding sliding groove, of each sliding block, first teeth are arranged on the sides, away from the sliding blocks, of the vertical rods, a pin shaft is fixedly connected to the rear inner wall of the box body, and two arc-shaped covers are rotatably connected to the box body through the pin shaft; a plurality of screen holes are formed in the outer wall of the arc-shaped cover in a penetrating mode, second teeth are further arranged on the outer walls of the arc-shaped covers, and the first teeth are meshed with the second teeth. The horizontal spiral wing type detachable water meter impeller protection equipment can prevent the impeller from being damaged by foreign objects and is convenient to clean the impeller.

Description

technical field [0001] The invention relates to the technical field of protection devices, in particular to a horizontal screw-wing detachable water meter impeller protection device. Background technique [0002] For water pump impeller cast iron production. The blades on the impeller of the water pump play a major role again, and the shape and size of the impeller of the water pump are closely related to the performance of the water pump. Pump impellers can generally be divided into two types: single-suction and double-suction. The single-suction impeller absorbs water on one side, and the impellers of small-flow pumps are mostly of this type. The double-suction impeller absorbs water on both sides, and the impellers of large-flow water pumps all adopt double-suction impellers. [0003] Protective equipment refers to equipment made for the safety of some equipment. [0004] For example, the Chinese patent application number CN201810614282.2, "A Concrete Storage and Prot...
