[0024] The following is combined with Figure 1-6 To further explain this application in detail,

[0025] The present application embodiment discloses a sewage pipe network overflow protection mechanism in rainy season. Figure 1 and Figure 2 A sewage pipe network overflow protection mechanism in rainy season, comprising a pipe body 1; an anti-overflow mechanism 2 is arranged in the inner cavity of the pipe body 1, and a cleaning mechanism 3 is arranged in the inner cavity of the pipe body 1;

[0026] The anti-overflow mechanism 2 includes a mounting tube 201, the surface of the mounting tube 201 is threadedly connected to the inner cavity of the tube body 1, the inner cavity of the mounting tube 201 is fixedly connected to a fixed tube 202, the inner wall of the mounting tube 201 is fixedly connected to a support rod 203, the inner cavity of the support rod 203 is slidably connected to a moving rod 206, one end of the moving rod 206 is fixedly connected to a sealing plate 207, the bottom of the sealing plate 207 is fixedly connected to an airbag 208, the top of the sealing plate 207 is in close contact with the bottom of the fixed tube 202, and the inner cavity of the fixed tube 202 is fixedly connected to the airbag 208. A support ring 204 is fixedly connected to the wall, and a filter net 205 is placed on the top of the support ring 204; by setting the anti-overflow mechanism 2, in the rainy season, when the sewage in the tube body 1 overflows upward, the buoyancy of the airbag 208 and the upward impact force of the sewage on the airbag 208 cause the sealing plate 207 to move upward, so that the sealing plate 207 blocks the fixed pipe 202, thereby achieving the effect of preventing sewage from overflowing, and the filter net 205 is placed above the fixed pipe 202, so as to facilitate the removal and cleaning of the filter net 205.

[0027] Reference Figure 2 and Figure 5 The cleaning mechanism 3 includes a pipe cover 301, the bottom of the pipe cover 301 is in close contact with the top of the installation pipe 201, the inner cavity of the pipe cover 301 is rotatably connected with a rotating shaft 302, and a cleaning brush 303 is fixedly connected to the surface of the rotating shaft 302. There are two cleaning brushes 303, the bottom of one cleaning brush 303 is in contact with the top of the filter screen 205, and the bottom of the other cleaning brush 303 is in contact with the top of the pipe cover 301. By setting the cleaning mechanism 3, when the filter screen 205 and the pipe cover 301 are blocked, the rotating shaft 302 can be rotated first, so that the cleaning brush pushes the impurities on the top of the filter screen 205 and the pipe cover 301, so that the filter screen 205 and the pipe cover 301 are partially in a flowing state, thereby temporarily avoiding sewage blockage. After use, the filter screen 205 and the pipe cover 301 are disassembled and cleaned;

[0028] Reference Figure 3 A sealing ring 4 is fixedly provided on the surface of the mounting tube 201, and the surface of the sealing ring 4 is in close contact with the surface of the tube body 1. The sealing ring 4 is made of rubber. By providing the sealing ring 4, after the mounting tube 201 is installed, the sealing ring 4 can achieve a sealing effect between the tube body 1 and the mounting tube 201;

[0029] Reference Figure 2 The top of the mounting tube 201 is fixedly connected with a clamping block 5, and the number of the clamping blocks 5 is two. The top of the tube cover 301 is provided with a clamping hole 6 used in conjunction with the clamping block 5. By setting the clamping block 5 and the clamping hole 6 for use in conjunction, when the tube cover 301 is placed, the clamping block 5 is clamped in the clamping slot, thereby preventing the tube cover 301 from rotating;

[0030] Reference Figure 2 The top of the tube cover 301 and the top of the filter screen 205 are both fixedly connected with a connecting block 7, and the number of the connecting blocks 7 is two. By providing the connecting block 7, the user pinches the connecting block 7 to achieve the effect of conveniently taking the filter screen 205 and the tube cover 301;

By setting the spring 8, the spring 8 adopts a spring 8 with a small elastic coefficient. When not in use, the sealing plate 207 is in contact with the fixed tube 202 by the force of the spring 8. When in use, the gravity of the water will drive the spring 8 to deform under force, so that the sealing plate 207 is no longer in contact with the fixed tube 202.

[0032] Reference Figure 6 A guide hole 9 is provided at the top of the support rod 203, and the inner cavity of the guide hole 9 is slidably connected to the surface of the moving rod 206. By providing the guide hole 9, when the moving rod 206 is moved, the guide hole 9 can guide the moving rod 206 to prevent the moving rod 206 from deflecting.

[0033] Working principle: in the rainy season, when the sewage in the tube body 1 overflows upward, the buoyancy of the airbag 208 and the upward impact force of the sewage on the airbag 208 cause the sealing plate 207 to move upward, so that the sealing plate 207 blocks the fixed tube 202, thereby achieving the effect of preventing sewage from overflowing, and the filter 205 is placed above the fixed tube 202, so that it is convenient to take and clean the filter 205, and when the filter 205 and the tube cover 301 are blocked, the rotating shaft 302 can be rotated first, so that the cleaning brush pushes the impurities on the top of the filter 205 and the tube cover 301, so that the filter 205 and the tube cover 301 are partially in a flowing state, thereby temporarily avoiding sewage blockage, and after use, the user pinches the connecting block 7 to disassemble and clean the filter 205 and the tube cover 301.
