The overflow device 2 is provided with a lever adjusting mechanism, when the river water level is lower than a certain threshold value, the lever adjusting mechanism enables the overflow device to be opened, water in the rain and sewage flow pipe is discharged from the sewage discharge pipe through the water outlet pipe, when the river water level is equal to or higher than a certain threshold value, the lever adjusting mechanism enables the lever adjusting mechanism to enable the overflow device to be closed, and water in the rain and sewage flow pipe is discharged into the river.
Preferably, the lever adjustment mechanism may be implemented as follows: the vertical rod 4, the lever 5 and the pontoon 6 form a lever adjusting mechanism, and the overflow device 2 is controlled to be closed and opened by means of the river water level. Since the overflow means are arranged near the end of the flow duct, only the section of the flow duct near the end will be described hereinafter.
Fig. 1 is a schematic diagram of the flow direction of water in the rain and sewage diversion automatic control apparatus when there is no rainfall or the amount of rain water is small, and the structure of the rain and sewage diversion automatic control apparatus is exemplified below with reference to fig. 1. The rain and sewage flow pipe 1 is in a horizontal state in the river channel (in practice, the invention does not limit the rain and sewage flow pipe, the rain and sewage flow pipe can be arranged obliquely or vertically), and the tail end of the rain and sewage flow pipe 1 is gradually bent and extended upwards to form a first overflow port 1-1. When the water level in the rainwater and sewage converging pipe 1 reaches the height of the first overflow port 1-1, the water in the rainwater and sewage converging pipe 1 is discharged into the river from the first overflow port 1-1. An overflow device 2 is arranged beside the rainwater and sewage converging pipe 1, a water inlet pipe 2-1 of the overflow device 2 is communicated with the bottom of the rainwater and sewage converging pipe 1, and a water outlet pipe 2-3 of the overflow device 2 is communicated with a sewage draining pipe 3. The overflow 2 may be arranged at a lateral position of the pipe near the end of the storm drain 1. A second overflow port 2-2 is provided in the overflow device 2, the second overflow port 2-2 may be, but is not limited to being, provided horizontally, a stopper 4-1 is provided on the second overflow port 2-2, and the stopper 4-1 extends upwards to form a vertical rod 4. As shown in FIG. 1, the overflow device 2 adopts a vertical pipe, a water inlet pipe 2-1 horizontally extends from the right side of the pipe, a water outlet pipe 2-3 horizontally extends from the left side of the pipe, and the water inlet pipe 2-1 and the water outlet pipe 2-3 can be hard pipelines or plastic hoses. The horizontal second overflow port 2-2 is arranged along the inner side of the vertical pipe, and the upper pipe orifice is partially closed, so that the vertical rod 4 can only pass through the pipe vertically, and the vertical rod 4 is beneficial to centralizing. A plug 4-1 is arranged at the lower end of the vertical rod 4. The support 5-2 is fixedly connected with the rain and sewage converging pipe 1 or the overflow device 2, the support 5-1 is vertically fixed on the support 5-2, and the lever 5 is swingably supported on the support 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 pontoon connecting rod 6-1, the lower end of the pontoon connecting rod 6-1 is connected with the pontoon 6, and the vertical rod 4, the lever 5 and the pontoon 6 together form a lever adjusting mechanism. The up-and-down movement of the pontoon 6 causes the vertical bar 4 to move up-and-down, thereby opening or closing the second overflow port 2-2 by the stopper 4-1.
In non-rainfall or non-heavy rainfall weather, the river water level is low, the pontoon 6 is in a suspended state, or a part of the pontoon 6 is immersed in the river water, but the buoyancy is insufficient to depress the choke plug 4-1 via the lever 5. Under the action of the lever 5, the vertical rod 4 and the plug 4-1 fixedly connected with the lower end of the vertical rod are lifted, namely, the second overflow port 2-2 is in an open state, sewage or a small amount of rainwater in the rainwater and sewage converging pipe 1 enters the overflow device 2, overflows from the second overflow port 2-2 to the water outlet pipe 2-3, and is discharged from the sewage discharging pipe 3 to a sewage collecting tank or a sewage treatment plant for centralized treatment, and the water flow direction is shown by an arrow in fig. 1. FIG. 2 is a schematic diagram of the flow direction of water in the rain and sewage diversion automatic control device when the amount of rainwater is large. The direction of which is indicated by the arrow in figure 2. In continuous rainfall or heavy rain weather, the river water level rises rapidly due to large rainwater quantity, the pontoon 6 floats completely, the vertical rod 4 and the plug 4-1 fixedly connected with the lower end of the vertical rod are pressed down under the action of the lever 5, the plug 4-1 completely plugs the second overflow port 2-2, the higher the water level rises, the greater the pressure of the plug 4-1 plugging the second overflow port 2-2, the channel leading to the sewage drain pipe 3 is blocked, a large amount of rainwater in the rainwater and sewage converging pipe 1 cannot flow to a sewage collecting pond or a sewage treatment plant through the second overflow port 2-2, and the rainwater can only be discharged into the river through the first overflow port 1-1 of the rainwater and sewage converging pipe 1.
After rain stop, the river water level falls, and the pontoon 6 also falls. However, when the water level in the river is higher than the first overflow port 1-1, the buoyancy force born by the pontoon always enables the plug 4-1 to press the second overflow port, and the rainwater continuously flows out from the first overflow port 1-1.
For the setting of the lever adjustment mechanism, it should be satisfied that: at the latest, when the river water level rises to the first overflow port 1-1, the plug 4-1 presses the second overflow port, and rainwater can only flow out from the first overflow port 1-1. At the earliest, when the river water level is lowered to the first overflow port 1-1, the buoyancy of the pontoon is reduced to enable the plug 4-1 to be lifted, and sewage can be continuously discharged from the second overflow port. That is, when the river water level is lower than the height of the first overflow port, the second overflow port is in an open state, so that water in the rain sewage flow pipe flows to the water outlet pipe through the second overflow port, and when the river water level is equal to or higher than the height of the first overflow port, the second overflow port is in a closed state, so that water in the rain sewage flow pipe is discharged into the river through the first overflow port. Therefore, the second overflow port can be prevented from being opened when the river channel water level is higher than that of the first overflow port, and a large amount of rainwater flows back into the sewage treatment plant through the second overflow port.
The rain and sewage diversion automatic control device of the embodiment realizes the automatic diversion of rain and sewage by means of natural fluctuation of the water level of the river channel. The overflow device is not required to be driven by electricity or manually, is very flexible to open and close, is arranged at the tail end of the rainwater and sewage flow pipe, is convenient to construct, is simple to install and debug, is low in manufacturing cost and has practical value.

The river water level can be effectively ensured to be slightly higher than the bottom end of the rainwater and sewage converging pipe 1, but can still be blocked outside the pipeline without backflow. In rainy days, the river water level rises slightly, but the dirty initial rainwater can be effectively shunted to a sewage treatment plant.
In an alternative embodiment, the end of the rain and sewage flow pipe adopts a corrugated pipe or a flexible pipe, and the corrugated pipe or the flexible pipe has elasticity in the axial direction and can bend in the radial direction, so that the included angle between the end surface of the end of the first overflow port and the vertical surface is adjustable within the range of 15-90 degrees.
In an alternative embodiment, the bottom of the rain and sewage converging pipe 1 is provided with a drop pit 1-2 communicated with the rain and sewage converging pipe 1, as shown in fig. 2, the drop pit 1-2 is provided with a certain accommodating space, sewage firstly flows into the drop pit 1-2, and sediment in the sewage can be effectively trapped in the drop pit 1-2. When the amount of the rainwater is large, the second overflow port 2-2 is closed, a large amount of the rainwater directly washes the sediment into the ship cabin or the river,
in an alternative embodiment, in order to facilitate the rainwater to wash the sediment into the ship cabin or the river, the two ends of the drop pit 1-2 along the axial direction of the rainwater and sewage converging pipe 1 have a certain gradient, so that the sediment can flow conveniently.
In an alternative embodiment, the water outlet pipe 2-3 and the sewage draining pipe 3 of the overflow device 2, and the water inlet pipe 2-1 and the drop pit 1-2 are detachably connected, so that maintenance and maintenance of the overflow device 2 are facilitated.
In an alternative embodiment, at least one of the water inlet pipe 2-1 and the water outlet pipe 2-3 adopts a corrugated pipe, and the corrugated pipe has certain elasticity in the axial direction, so that the installation error can be effectively eliminated.
In an alternative embodiment, a plurality of float installation holes 6-2 are vertically provided at a certain interval on the float connecting rod 6-1, and the opening and closing time of the second overflow port 2-2 of the overflow device 2 can be adjusted by changing the installation position of the float 6. For example, the float 6 is mounted on the lower float mounting hole 6-2 relatively earlier than the upper float mounting hole 6-2, and the second overflow port 2-2 is closed. Because the positions of the rain and sewage flow pipes 1 are different in the river channels, the common water level of each river channel is also different, and the height of the pontoon can be adjusted according to different heights, short terrains and the water level of the river channel, so that the optimal time node for closing and opening the second overflow port 2-2 in the overflow device is adjusted.
In an alternative embodiment, the plug 4-1 may be spherical, in the shape of a sphere, in the shape of a frustum, and accordingly, the second overflow 2-2 may have a slit that mates with the plug 4-1 to tightly seal the second overflow 2-2.
