Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of water flow indicator, including ontology 1, setting
Water inlet end flanges 13 and water outlet end flanges 4 at 1 both ends of the ontology, are equipped with an axis pin 8, the axis pin 8 on the ontology 1
It is set on ontology 1 and is vertically arranged with 1 center of the ontology, oscillating rod 5 is arranged on the axis pin 8, the oscillating rod 5 passes through
It wears 1 side wall of ontology and its 1 center of end phase ontology to extend, the end of the oscillating rod 5 is equipped with a wheel shaft 3, on the wheel shaft 3
The blade 2 that direction is oriented water inlet end, the wheel shaft 3 and 2 integrally connected of blade, the wheel shaft 3 and the oscillating rod 5 are installed
Between be clearance fit, the upper end of the oscillating rod 5 is equipped with a feeler lever 14 being laterally arranged, and the feeler lever 14 is fixedly mounted on
5 upper end of oscillating rod, the oscillating rod 5 are connected to the medium position of feeler lever 14, and spring 15, the bullet are equipped on the feeler lever 14
The quantity of spring 15 is two, and 15 one end of one of spring is connected, in addition with 9 inner wall of protective shell mounted on 1 top of ontology
One end is connected to the side of oscillating rod 5, another 15 one end of spring is connected to 5 side of oscillating rod, other end and is located at institute
It states the time relay 12 inside protective shell 9 to be connected, the time relay 12 is by conducting wire and is arranged inside protective shell 9
