System and method for dynamically detecting and distributing water for garden

Abstract

The invention relates to a system and a method for dynamically detecting and distributing water for a garden. The system comprises water sources, a water quality detecting unit, a distributing unit, a temporary storage reservoir, a reclaimed water connecting pipe and a sewage connecting pipe; a water quality detecting main power source is arranged at a water inlet of the water quality detecting unit, water of each water source flows into the water quality detecting unit via the water inlet and flows out of the water quality detecting unit from an overflow opening in an opening state, and the water of each water source directly flows to the overflow opening from the water inlet in a closed state; and the temporary storage reservoir is provided with an inlet and an outlet, a buffer cavity is arranged at the inlet, an impeller unit is arranged in the buffer cavity and comprises a variable-pitch spiral impeller assembly, a positioning bearing, a rotary shaft and a support, the shape of each blade of an n variable-pitch spiral impeller of the variable-pitch spiral impeller assembly meets trajectory equations of X<1>=rXcos(theta<1>+2XpiXn/N), Y<1>=rXsin(theta<1>+2XpiXn/N) and Z<1>=(n-1)X(L+a)/N+[theta<1>/(2Xpi)]<m>X[L-(N-1)Xa]/N, the n is larger than or equal to 1 and is smaller than or equal to the N, a trajectory corresponding to the trajectory equations extends from one end, which is close to a water inlet valve, of the pitch-variable spiral impeller to the other end of the pitch-variable spiral impeller.

Description

technical field [0001] The invention relates to a water quality detection and automatic diversion system, in particular to a reclaimed water detection and automatic diversion system. Background technique [0002] "Reclaimed water" is the so-called reclaimed water. Usually people call tap water "upper water" and sewage "downwater". The quality of reclaimed water is between upper water and downwater, hence the name "reclaimed water". Although regenerated water is not drinkable, it can be used in occasions where the water quality is not high, such as flushing toilets, flushing cars, spraying roads, greening, etc. Reclaimed water engineering technology can be considered as a miscellaneous water supply technology between the building's domestic water supply system and drainage system. The water quality index of reclaimed water is lower than the water quality index of drinking water in urban water supply, but higher than the discharge standard of polluted water allowed to be disc...
