Initial rainwater discarding device of rainwater gathering system

Abstract

The invention discloses an initial rainwater discarding device of a rainwater gathering system. The initial rainwater discarding device of the rainwater gathering system comprises a shell, a water inlet passage, and a rainwater discarding passage and a water discharge passage which are separated from each other, a current guide piece, a rotating piece, a first limit piece and a second limit piece are arranged in the shell, an outfall is formed in the water inlet passage, the current guide piece is located below the outfall and provided with a current guide passage, one end of the current guide passage is located above the rainwater discarding passage while the other end is located above the water discharge passage, and the rotating piece is connected with the current guide piece and enables the current guide piece to rotate around an axle center at the middle of the current guide passage; the first limit piece limits the oblique state of the current guide passage towards one end of the rainwater discarding passage, the second limit piece limits the oblique state of the current guide passage towards one end of the water discharge passage, and under the normal state, the current guide passage inclines towards one end of the rainwater discarding passage. The initial rainwater discarding device of the rainwater gathering system does not have power consumption, does not use electricity and power and has advantages of low maintenance cost, good rainwater discarding effect and the like.

Description

technical field [0001] The invention relates to a rainwater collection system, in particular to an initial waste flow device of the rainwater collection system. Background technique [0002] The initial flow abandonment device of the rainwater collection system in the prior art usually uses structures such as solenoid valves and floating balls to realize the initial rainwater abandonment.
