[0019] Compared with the prior art, the present utility model provides an anti-backflow rain and sewage shunt device, which has the following beneficial effects:

[0020] 1. In this anti-backflow rain and sewage diversion device, when using the anti-backflow rain and sewage diversion device, first fix the retaining column inside the diversion device body through the mounting plate and fastening nut, then install the diversion device body underground, and then connect the water inlet pipe to the sewage pipe. When it starts to rain, the water in the sewer is mainly sewage, and the sewage enters the inside of the diversion device body through the water inlet pipe and then flows out through the sewage pipe. As the rainfall increases sharply, the water level inside the diversion device body rises, and the float drives the blocking block to block the sewage pipe through the lever principle. Then the rainwater flows into the outer river through the rainwater pipe. When the rainfall decreases, the float descends and causes the blocking block to move upward through the balance plate. During the upward movement of the balance plate, the stop block will restrict the balance plate. Through the setting of the retaining column and the protective ball, it can restrict and protect the balance plate, preventing the excessive upward movement of the balance plate from affecting the normal use of the diversion device body.

[0021] 2. In this anti-backflow rain and sewage diversion device, when using the anti-backflow rain and sewage diversion device, first install the mounting block on the left inner wall of the diversion device body, then bond the protective pad to the left side of the protective plate, then connect the rotating pipe to the protective plate, and then install the rotating pipe in front of the mounting block. When the diversion device body is draining normally, the rainwater impacts the protective plate through the water inlet pipe, causing the rotating pipe to rotate, thereby opening the protective plate. When the water level of the outer river rises above the rainwater pipe, the protective plate will return to its original position due to the rotation of the rotating pipe, so that the protective plate and the protective pad will block the rainwater pipe to prevent river water from flowing back. Through the setting of the protective plate and the protective pad, the anti-backflow performance of the diversion device body is enhanced, so that this anti-backflow rain and sewage diversion device can be used better.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The present invention provides an Figure 1-6 anti-backflow rain and sewage diversion device as shown in the figure. An anti-backflow rain and sewage diversion device includes a shunt device body 1 and a water inlet pipe 2 provided at the left side position of the shunt device body 1; a rainwater pipe 9 is provided at the right side position of the shunt device body 1, and a protection plate 16 is connected to the right side position of the rainwater pipe 9; a sewage pipe 12 is provided at the lower end position of the shunt device body 1; a turntable 3 is installed at the inner left side position of the shunt device body 1, a rotating shaft 4 is installed at the front position of the turntable 3, and a balance plate 13 is provided at the front position of the turntable 3 and at the outer side position of the device; a floating ball 15 is provided at the lower left side position of the balance plate 13, a second through hole 14 is provided at the outer wall position of the floating ball 15, a plug 11 is provided at the lower right side position of the balance plate 13, and the balance plate 13 is connected to the floating ball 15 and the plug 11 through an elastic band 10; a stop post 5 is installed at the upper inner side of the shunt device body 1 and above the balance plate 13, a first through hole 7 is provided at the inner position of the stop post 5, and a protection ball 8 is provided at the lower end position of the stop post 5. Through the settings of the stop post 5 and the protection ball 8, the balance plate 13 can be restricted and protected.

[0031] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, in order to prevent the balance plate 13 from rising too much and affecting the normal use of the shunt device body 1, when using the anti-backflow rain and sewage shunt device, first fix the stop post 5 inside the shunt device body 1 through the mounting plate 6 and the fastening nut, then install the shunt device body 1 underground, and then connect the water inlet pipe 2 to the sewer pipe. When it starts to rain, the water in the sewer is mainly sewage, and the sewage enters the inside of the shunt device body 1 through the water inlet pipe 2 and then flows out through the sewage pipe 12. As the rainfall increases sharply, the water level inside the shunt device body 1 rises, and the float ball 15 drives the plug 11 to block the sewage pipe 12 through the lever principle. Then the rainwater flows into the outer river through the rainwater pipe 9. When the rainfall decreases, the float ball 15 descends and causes the plug 11 to move upward through the balance plate 13. During the upward movement of the balance plate 13, the stop block will limit the balance plate 13. Through the settings of the stop post 5 and the protective ball 8, the balance plate 13 can be restricted and protected, preventing the balance plate 13 from rising too much and affecting the normal use of the shunt device body 1.

[0032] A plurality of first through holes 7 are provided in total. The plurality of first through holes 7 penetrate the stop post 5 at equal intervals. The stop post 5 and the protective ball 8 are connected by bonding. The protective ball 8 is a solid hemispherical structure and is made of rubber material. Through the setting of the first through holes 7, the impact force of rainwater on the stop post 5 can be reduced.

[0033] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, in order to reduce the impact force of rainwater on the stop post 5 and extend the service life of the stop post 5, when using the anti-backflow rain and sewage shunt device, first fix the stop post 5 inside the shunt device body 1 through the mounting plate 6 and the fastening nut, then install the shunt device body 1 underground, and then connect the water inlet pipe 2 to the sewer pipe. As the rainfall increases sharply, the water level inside the shunt device body 1 rises, and the float ball 15 drives the plug 11 to block the sewage pipe 12 through the lever principle. Then the rainwater will impact the stop post 5, and the rainwater passes through the first through holes 7 inside the stop post 5, thereby reducing the impact force of rainwater on the stop post 5. Then the rainwater flows into the outer river through the rainwater pipe 9. Through the setting of the first through holes 7, the impact force of rainwater on the stop post 5 can be reduced, thereby extending the service life of the stop post 5.

[0034] On the inner upper wall of the shunt device body 1 and at the upper end position of the retaining post 5, a mounting plate 6 is provided. Inside the mounting plate 6, mounting holes are provided. On the inner upper wall of the shunt device body 1 and at the position corresponding to the mounting holes, connection holes are provided. Internal threads are provided on the inner wall positions of the mounting holes and the connection holes. Inside the mounting holes and the connection holes and at the lower end position of the mounting plate 6, fastening nuts are provided. External threads are provided on the outer wall positions of the fastening nuts. The fastening nuts are connected to the internal threads on the inner walls of the mounting holes and the connection holes through the external threads on their outer walls, so that the mounting plate 6 is installed inside the shunt device body 1, and further the retaining post 5 is installed inside the shunt device body 1.

[0035] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, in order to facilitate the installation and disassembly of the retaining post 5, when using the anti-backflow rain and sewage shunt device, first connect the mounting plate 6 with the retaining post 5, then place the mounting plate 6 on the inner upper wall of the shunt device body 1, so that the mounting holes inside the mounting plate 6 are aligned with the connection holes on the inner upper wall of the shunt device body 1. Then insert the fastening nuts into the inside of the mounting holes and the connection holes. The fastening nuts are connected to the internal threads on the inner walls of the mounting holes and the connection holes through the external threads on their outer walls, so that the mounting plate 6 is installed inside the shunt device body 1, and further the retaining post 5 is installed inside the shunt device body 1. Through the setting of the mounting plate 6 and the fastening nuts, the installation and disassembly of the retaining post 5 are facilitated, and thus the installation and disassembly of the retaining post 5 become more convenient.

[0036] On the left inner wall of the shunt device body 1 and at the right position of the water inlet pipe 2, a mounting block 19 is provided. At the front position of the mounting block 19, a rotating pipe 18 is installed. At the lower end position of the rotating pipe 18, a protective pad 17 is connected. The protective pad 17 is made of rubber material. Through the setting of the protective plate 16 and the protective pad 17, the anti-backflow performance of the shunt device body 1 is enhanced.

[0037] As Figure 2 , Figure 5 and Figure 6As shown in the figure, in order to enhance the anti-backflow performance of the shunt device body 1, when using the anti-backflow rain and sewage shunt device, first install the installation block 19 on the left inner wall of the shunt device body 1, then bond the protective pad 17 to the left side of the protective plate 16, then connect the rotating pipe 18 to the protective plate 16, and then install the rotating pipe 18 in the front of the installation block 19. When the shunt device body 1 is draining normally, the rainwater passing through the water inlet pipe 2 will impact the protective plate 16, causing the rotating pipe 18 to rotate, so that the protective plate 16 opens. When the water level of the outer river rises above the rainwater pipe 9, the protective plate 16 will return to its original position due to the rotation of the rotating pipe 18, so that the protective plate 16 and the protective pad 17 will block the rainwater pipe 9 to prevent river water from flowing back. Through the setting of the protective plate 16 and the protective pad 17, the anti-backflow performance of the shunt device body 1 is enhanced, so that the anti-backflow rain and sewage shunt device can be better used.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
