The overflow device 2 is provided with a lever adjustment mechanism. When the water level of the river is lower than a certain threshold, the lever adjustment mechanism makes the overflow device open, and the water in the rain-sewage confluence pipe is discharged from the sewage pipe through the outlet pipe. When the water level of the river is equal to Or when it is higher than a certain threshold, the lever adjustment mechanism makes the lever adjustment mechanism close the overflow device, and the water in the rain-sewage confluence pipe is discharged into the river channel.

Preferably, the lever adjustment mechanism can be realized in the following manner: the lever adjustment mechanism is composed of the vertical rod 4, the lever 5 and the buoy 6, and the overflow device 2 is controlled to close and open by means of the river water level. Since the overflow device is arranged near the end of the rain-sewage confluence pipe, only a section near the end of the rain-sewage confluence pipe will be described below.

Figure 1 is a schematic diagram of the water flow in the rain and sewage diversion automatic control device when there is no rainfall or the amount of rainwater is small. The structure of the rain and sewage diversion automatic control device is illustrated below with reference to Figure 1 . The rain-sewage confluence pipe 1 is in a horizontal state in the river channel (in fact, the utility model has no restrictions on the rain-sewage confluence pipe, and the rain-sewage confluence pipe can be placed obliquely or vertically), and the end of the rain-sewage confluence pipe 1 gradually bends upwards and extends , forming the first overflow port 1-1. When the water level in the rain-sewage confluence pipe 1 reaches the height of the first overflow port 1-1, the water in the rain-sewage confluence pipe 1 is discharged into the river channel from the first overflow port 1-1. An overflow device 2 is installed beside the rain-sewage confluence pipe 1, the water inlet pipe 2-1 of the overflow device 2 communicates with the bottom of the rain-sewage confluence pipe 1, and the outlet pipe 2-3 of the overflow device 2 is connected with the sewage pipe 3 Pass. The overflow device 2 can be arranged on the side of the pipe near the end of the rain-sewage confluence pipe 1 . A second overflow port 2-2 is provided in the overflow device 2, and the second overflow port 2-2 can be but not limited to be set horizontally, and a plug 4-2 is provided on the second overflow port 2-2. 1. The plug 4-1 extends upwards out of the vertical rod 4. As shown in Figure 1, the overflow device 2 adopts an upright pipe, and the water inlet pipe 2-1 extends horizontally on the right side of the pipe material, and the water outlet pipe 2-3 extends horizontally on the left side of the pipe material, and the water inlet pipe 2-1 and Outlet pipe 2-3 both can adopt hard pipeline, also can adopt plastic hose. A horizontal second overflow port 2-2 is arranged along the inside of the erected pipe, and the upper end of the nozzle is partially closed, so that only the vertical rod 4 can pass up and down, which is beneficial to erecting the vertical rod 4. A plug 4-1 is set at the lower end of the vertical rod 4. The bracket 5-2 is fixedly connected with the rain-sewage confluence pipe 1 or the overflow device 2, the pole 5-1 is vertically fixed on the bracket 5-2, and the lever 5 is swingably supported on the pole 5-1. One end of the lever 5 is connected with the upper end of the vertical rod 4, the other end of the lever 5 is connected with the buoy connecting rod 6-1, and the lower end of the buoy connecting rod 6-1 is connected with the buoy 6, and the vertical rod 4 is in common with the lever 5 and the buoy 6. Constitutes a lever adjustment mechanism. The up and down movement of the buoy 6 can impel the vertical rod 4 to move up and down, thereby opening or closing the second overflow port 2-2 by the plug 4-1.

In no rainfall or non-heavy rainfall weather, the river water level is low, and the buoy 6 is suspended, or a part of the buoy 6 is immersed in the river water, but its buoyancy is not enough to depress the plug 4-1 by the lever 5 . Under the action of the lever 5, the vertical rod 4 and the plug 4-1 fixedly connected to its lower end are lifted, that is, the second overflow port 2-2 is in an open state, and the sewage or a small amount of rainwater in the rain-sewage confluence pipe 1 enters The overflow device 2 overflows from the second overflow port 2-2 to the outlet pipe 2-3, and then discharges from the sewage pipe 3 to the sewage collection tank or sewage treatment plant for centralized treatment, and its water flow direction is shown in Figure 1 indicated by the arrow. Fig. 2 is a schematic diagram of the flow direction of the water flow in the rain-sewage diversion automatic control device when the amount of rainwater is large. The direction of the water flow is shown by the arrow in Figure 2. In continuous rainfall or rainstorm weather, the large amount of rainwater causes the water level of the river to rise rapidly, and the buoy 6 floats up completely. Under the action of the lever 5, the vertical rod 4 and the plug 4-1 fixedly connected to the lower end are pressed down, and the plug 4 -1 completely blocks the second overflow port 2-2, the higher the water level rises, the greater the pressure that the plug 4-1 blocks the second overflow port 2-2, the passage leading to the sewage pipe 3 is blocked Blocked, a large amount of rainwater in the rain-sewage confluence pipe 1 can not flow to the sewage collection tank or sewage treatment plant through the second overflow port 2-2, and can only be discharged through the first overflow port 1-1 of the rainwater confluence pipe 1 to In the river.

After the rain stops, the water level of the river course drops, and the buoy 6 also drops thereupon. But, when the water level in the river course was higher than the first overflow port 1-1, the buoyancy of the buoyant drum made the plug 4-1 press the second overflow port all the time, and the rainwater continued to flow out from the first overflow port 1-1.

For the setting of the lever adjustment mechanism, it should be satisfied that: when the river water level rises to the first overflow port 1-1 at the latest, the plug 4-1 will press the second overflow port, and the rainwater can only flow from the first overflow port 1-1. -1 outflow. When the water level of the river channel drops to the first overflow port 1-1 at the earliest, the buoyancy force suffered by the buoy is reduced to such that the plug 4-1 is lifted, and the sewage can continue to be discharged from the second overflow port. That is to say, when the water level of the river channel is lower than the height of the first overflow opening, the second overflow opening is in an open state, so that the water in the rain-sewage confluence pipe flows through the second overflow opening to the The water outlet pipe, when the water level of the river is equal to or higher than the height of the first overflow port, the second overflow port is in a closed state, so that the water in the rain-sewage confluence pipe is discharged through the first overflow port into the river. This can prevent the second overflow from opening when the river water level is higher than the first overflow, and a large amount of rainwater will be poured into the sewage treatment plant through the second overflow.

The rain and sewage diversion automatic control device in this embodiment realizes the automatic rain and sewage diversion by relying on the natural fluctuation of the river water level. Neither electric drive nor manpower is required. The overflow device is very flexible to open and close.

It can effectively ensure that although the water level of the river course is slightly higher than the bottom of the rain-sewage confluence pipe 1, it can still be blocked outside the pipe without backflow. In rainy days, although the water level of the river course rises slightly, it can still effectively divert the dirty initial rainwater to the sewage treatment plant.

In an optional embodiment, the end of the rain-sewage confluence pipe adopts a bellows or a flexible pipe. Since the bellows or flexible pipe has elasticity in the axial direction, it can be bent in the radial direction, so that the end surface of the end of the first overflow port The included angle with the vertical plane is adjustable within the range of 15°-90°.

In an optional embodiment, the bottom of the rain-sewage confluence pipe 1 is provided with a puddle 1-2 communicating with the rain-sewage confluence pipe 1. As shown in FIG. 2, the puddle 1-2 has a certain accommodation space. Sewage first flows into the sinkhole 1-2, which can effectively trap the silt in the sewage in the sinkhole 1-2.

The opening and closing time of orifice 2-2. For example, relatively speaking, when the buoy 6 is installed on the lower buoy installation hole 6-2 compared with the upper buoy installation hole 6-2, the second overflow port 2-2 is closed earlier. Because in the river, the height of the rainwater confluence pipe 1 is different, and the water level of each river is also different. The height of the buoy can be adjusted according to the different heights and low terrains of each rainwater confluence pipe 1 and the water level of the adjacent river, so as to adjust the overflow. The optimal time point for closing and opening of the second overflow port 2-2 in the flow device.

In an optional embodiment, the plug 4-1 may be in the shape of a sphere, a spherical segment, or a truncated cone. Correspondingly, the second overflow port 2-2 has a cutout matching the plug 4-1, The second overflow port 2-2 can be tightly sealed.

In an optional embodiment, the buoy 6 may be one of spherical, ellipsoidal, polygonal sphere, cylindrical, and polygonal prism, or centered on the above-mentioned shape, the upper and lower ends are conical or pyramidal.
