Contents of the invention

The present invention aims to solve at least one of the technical problems existing in the prior art.

The technical solution adopted by the present invention to solve its technical problems is:

An initial waste flow device for a rainwater collection system, comprising a housing, a water inlet channel, a waste flow channel and a water outlet channel separated from each other, a guide piece, a rotating piece, a first limit piece and a second limit piece are arranged inside the shell. A position piece, the water inlet channel has a water outlet, the flow guide is located below the water outlet, the flow guide is provided with a flow guide channel, and one end of the flow guide channel is located above the discarded flow channel , the other end of the guide channel is located above the water outlet channel, the rotating member is connected to the guide member and makes the guide member rotate around an axis located in the middle of the guide channel; The first limiter restricts the diversion channel to be in an inclined state toward the discarding channel, and the second limiter restricts the diversion channel to be inclined toward the water outlet channel. Under normal conditions, the diversion channel One end of the discard flow channel is inclined.

The normal state means that in the state of not collecting rainwater, relative to the axis of rotation, the mass of the flow guide at one end of the abandonment channel is greater than the mass at the end of the outlet channel, so that the flow guide channel is inclined to the left under normal conditions.

In addition, the initial flow abandonment device of the rainwater collection system according to the embodiment of the present invention may also have the following additional technical features:

Preferably, the water inlet channel has an impact surface that is horizontal or faces an end of the flow guide channel that is close to the outlet channel. It can be seen that in the initial stage of rain, the amount of rainwater is small, and the rainwater falls almost vertically from the drain, and flows out to the end of the abandonment channel along the inclined direction of the diversion channel. When the amount of rainwater is large, the rainwater passes through at a faster speed. When the impact surface falls from the water outlet, it falls in a parabolic shape, which has an impact on the other end of the diversion channel. Under the action of the impact force, the diversion member tilts towards one end of the water outlet channel, thereby realizing rainwater collection. Further, the water outlet is located above the end of the diversion channel close to the abandonment channel, so as to avoid a large amount of rainwater at the beginning of the rain, causing the diversion member to overturn and the abandonment cannot be realized.

Preferably, the deflector includes a deflector and baffles located on both sides of the deflector, the deflector and the baffles enclose the flow guide channel. It can be seen from this that the deflector has a smooth deflector surface, and the baffle has the function of preventing rainwater from splashing to both sides.

Preferably, the rotating member includes a pin shaft and a bearing that cooperate with each other, and the pin shaft is connected to the middle of the flow guiding member. It can be seen that, through the pin shaft and the bearing, the deflector can freely rotate around the axis formed by the pin shaft.

Preferably, the first limiting member and the second limiting member are respectively arranged below the two ends of the flow guide channel.

Preferably, a partition is provided in the lower part of the housing, and the partition divides the lower part of the housing into two parts, and the two parts communicate with the waste flow channel and the water outlet channel respectively.

Preferably, a support is provided inside the housing, and a cross bar is provided on the support, and the cross bar is located below one end of the diversion channel close to the discarding channel to form the first stopper; the partition The upper end of the plate extends below the end of the guide channel close to the outlet channel, and the upper end of the partition forms the second limiting member. Further, the rotating member includes a pin shaft and a bearing that cooperate with each other, the pin shaft is connected to the middle of the flow guiding member, and the bearing is arranged on the bracket.

Preferably, a filter screen is provided inside the water outlet channel in the housing.

Preferably, a cover is provided at the water outlet, and the cover is connected to the water inlet channel through a hinge.

Preferably, an inspection well cover is provided on the upper part of the housing.

In the present invention, rainwater is discarded or collected according to the amount of rainwater in the rainwater collection process. In the initial stage of rainwater collection, the amount of rainwater is usually small, and the impact force of rainwater is small. On the inclined diversion channel, rainwater flows to the abandonment channel to realize the abandonment of rainwater. After the initial period, the amount of rainwater increases and the impact force also increases. Under the impact force of rainwater, the deflector rotates freely around the axis and tilts toward one end of the water outlet channel, and the rainwater flows out from the water outlet channel to realize rainwater collection. When the rain ends, the amount of rainwater decreases until it stops, and the guide member rotates to incline towards one end of the abandonment channel.

It can be seen from this that the initial flow abandonment device of the rainwater collection system of the present invention has the advantages of no power consumption, no electricity, no power, low maintenance cost, and good flow abandonment effect.

The right end of the discarding channel 3 is connected to the housing 1, with a diameter of 200 mm and a length of 300 mm. The water outlet channel 4 is located at the other end of the water inlet channel 2, with a diameter of 300mm and a length of 200mm. The left end of the water outlet channel 4 is connected to the housing 1, and the right end is a water outlet 11, which is used to connect to the rainwater collection tank. Paint (red) twice on the outside of the device as an anti-rust measure.

The water outlet 8 is provided with a cover 17, and the cover 17 is connected with the water inlet channel 2 through a hinge. The water inlet channel 2 has a horizontal impact surface 9 , that is, the lower surface inside the water inlet channel 2 . In the early stage of rainwater, the amount of rainwater is small, and the rainwater falls almost vertically from the 8 outlets, and flows out to the end of the abandonment channel 3 along the inclined direction of the diversion channel. When the amount of rainwater is large, the rainwater passes through the impact surface at a faster speed 9. When it falls from the water outlet 8, it falls in a parabolic shape, which has an impact on the other end of the diversion channel, and the diversion member tilts towards the end of the water outlet channel 4 under the impact force, thereby realizing rainwater collection.
