[0002] Separating rainwater and sewage is a method of drainage that separates rainwater and sewage for discharge or subsequent treatment. Rainwater is discharged directly into rivers through a stormwater network, while sewage is collected through a sewage network and sent to a sewage treatment plant for treatment. Separating rainwater and sewage facilitates rainwater collection, utilization, and centralized management and discharge. It also accelerates sewage collection and treatment rates, prevents sewage contamination of rivers and groundwater, significantly improves the urban water environment, and reduces sewage treatment costs.

DETAILED DESCRIPTION

[0015] The present invention is described in detail below with reference to the accompanying drawings.

[0016] like Figure 1-Figure 3As shown, a buoyancy automatic rainwater and sewage diversion device comprises a shell 1 and an outlet pipe 3 and an inlet pipe 2 respectively arranged in the middle of the left and right sides of the shell 1. The front part of the inlet pipe 2 extends into the shell 1. A limited flow groove 5 is provided at the lower front end of the inlet pipe 2. A vertical plate 18 is provided in the middle of the lower end of the shell 1. The upper end of the vertical plate 18 can be swung left and right to provide a diverter plate 7. The diverter plate 7 is located below the inlet pipe 2. The left end of the diverter plate 7 is connected to the buoyancy box 10 through the buoyancy box 10 bracket. The shell 1 is provided with a The water stop plate 6 is located on the right side of the flow limiting groove 5. The bottom of the shell 1 is provided with a sewage pipe 4 on the right side of the diverter plate 7, a limiting plate 11 is provided on the left side of the diverter plate 7, and the diverter plate 7 is provided with a ball control hole 8; in the sewage discharge state, the left side of the diverter plate 7 is limited by the limiting plate 11, the front end water outlet of the water inlet pipe 2 is located on the left side of the diverter plate 7, the diverter plate 7 is located on the left side of the flow limiting groove 5, and the ball control hole 8 is located above the sewage pipe 4; in the rain discharge state, the top of the diverter plate 7 is sealed and fitted with the water stop plate 6.

[0017] The present invention is designed based on the characteristics of small sewage runoff and large rainwater runoff. The diverter plate 7 divides the shell 1 into two spaces: a rainwater chamber 16 and a sewage chamber 17. During operation, sewage enters the equipment from the water inlet pipe 2, falls into the sewage chamber 17 through the flow limiting groove 5, and is discharged into the sewage network from the sewage pipe 4. Three flow limiting grooves 5 are provided at the lower front end of the water inlet pipe 2 from left to right, and a flow regulating sleeve is provided at the front end of the water inlet pipe 2. Slide the flow regulating sleeve left and right to block part of the flow limiting groove 5, and adjust the flow regulating sleeve according to the sewage discharge flow in the application scenario.

[0018] 6 , and the water level in the rainwater chamber 16 rises. As the water level in the rainwater chamber 16 rises, the buoyancy of the water causes the float box 10 to rise with the water level. The rise of the float box 10 pushes the diverter plate 7 to swing toward the water stop plate 6. The space in the sewage chamber 17 becomes smaller, and the space in the rainwater chamber 16 becomes larger. Finally, the upper part of the diverter plate 7 fits with the water stop plate 6. The water stop plate 6 is provided with a soft silicone pad. The diverter plate 7 fits on the silicone pad of the water stop plate 6. Under the buoyancy of the float box 10, the diverter plate 7 presses the silicone pad to achieve the purpose of sealing. At this time, the water falling from the flow limiting trough 5 falls on the diverter plate 7 and flows into the rainwater chamber 16. All the rainwater entering the water inlet pipe 2 flows into the rainwater chamber 16. The water level in the rainwater chamber 16 rises, and the rainwater flows out from the outlet pipe 3 and flows into the rainwater pipe network.

[0019] The pontoon 10 support includes a first pontoon frame 15 and a second pontoon frame 19 hingedly connected to the first pontoon frame 15 via a second hinge 13. The first pontoon frame 15 is connected to the diverter plate 7, and the second pontoon frame 19 is connected to the pontoon 10. A limit plate 14 is fixedly provided above the left end of the first pontoon frame 15, and the limit plate 14 extends leftward to above the right end of the second pontoon frame 19.

[0020] During operation, the water level in rainwater chamber 16 rises, lifting pontoon 10. This in turn drives second pontoon frame 19 upward. Limiting plates 14 restrict further upward movement of second pontoon frame 19, thereby driving first pontoon frame 15 upward. During this process, limiting plates 14 ensure that pontoon 10 exerts sufficient force on diverter plate 7. When diverter plate 7 is vertical, ball control hole 8 on diverter plate 7 is higher than the top of sewer pipe 4, preventing sewage from flowing into rainwater chamber 16. When rainfall ends, rainwater in rainwater chamber 16 flows through the ball control hole into sewer chamber 17 and out of sewer pipe 4. The water level in rainwater chamber 16 drops, and pontoon 10 follows the water level.

[0021] The pontoon 10 falls and drives the diverter plate 7 to move toward the rainwater chamber 16 until it touches the limit plate 11. The limit plate 11 limits the position of the diverter plate 7. When touching, the diverter plate 7 remains in a vertical state. Since the second pontoon frame 19 is connected to the first pontoon frame 15 through the second hinge 13, when the pontoon 10 falls back,

[0022] As the pontoon 10 falls, the second pontoon frame 19 continuously rotates along the second hinge 13, and the downward movement of the pontoon 10 increases. The pontoon 10 bracket forms an angle at the second hinge 13, which increases the force of the pontoon 10 to drive the diverter plate 7 to return to its original position, making it easier for the diverter plate 7 to rebound.

[0023] A sealing member 12 is provided at the first hinge 9 to play a waterproof role, sealing the first hinge 9 to prevent sewage in the sewage chamber 17 from flowing into the rainwater chamber 16.

[0024] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
