Description

Technical Field

[0001] The utility model relates to the technical field of rainwater and sewage diversion, in particular to a rainwater and sewage diversion structure. Background Art

[0002] Rainwater and sewage diversion is an important drainage system. Its main function is to separate rainwater and sewage, transport them through different pipes for discharge or subsequent treatment. By treating rainwater and sewage separately, sewage can be prevented from being discharged directly into rivers, thereby protecting the water environment and avoiding water pollution. Rainwater drain valve is a common rainwater and sewage diversion structure. Its function is to discharge the severely polluted water in the early stage of rainwater into the sewage pipe, and the water in the later stage of rainwater into the rainwater pipe.

[0003] The float is one of the core components of the rainwater discard device, and is mainly used to switch the drainage mode under the action of buoyancy. The current float of the rainwater discard device is a plastic float. Due to the complex composition of sewage, a large amount of impurities adhere to the surface of the float during long-term use, which causes the weight of the float to change, thereby affecting the diversion of rainwater and sewage. The plastic float is difficult to remove after the device is installed due to its fixed volume, and it is not convenient to clean it. Therefore, a rainwater and sewage diversion structure is proposed. Utility Model Content

[0027] Reference Figure 1-Figure 4 , is an embodiment of the utility model, which provides a rainwater and sewage diversion structure, comprising:

[0028] The main body 100 includes a waste flow well 101, the side wall of the waste flow well 101 is fixedly connected with an inlet pipe 102, a rainwater pipe 103 and a waste flow pipe 104, the inlet pipe 102 and the rainwater pipe 103 are located on the same horizontal line, the diameter of the inlet pipe 102 is three times that of the waste flow pipe 104, and a partition 105 is fixedly connected to the inner side of the waste flow well 101, and the partition 105 is located between the inlet pipe 102 and the waste flow pipe 104;

[0029] The filter assembly 200 includes a filter plate 201, which is vertically arranged and fixedly connected to the top of the partition 105, and a top plate 202 is fixedly connected to the top of the filter plate 201. The filter plate 201, the top plate 202 and the partition 105 cooperate to completely cover the rainwater pipe 103;

[0030] The diversion mechanism 300 includes a cross bar 301, one end of which is fixedly connected to the side of the filter plate 201 close to the water inlet pipe 102, and the other end is fixedly connected to the inner wall of the waste well 101. The cross bar 301 is provided with a through hole in the vertical direction, and a circular sewage outlet is provided at the position of the partition plate 105 facing the through hole. The cross bar 301 is matched with a hanging pipe 302 with a closed bottom, and the hanging pipe 302 vertically passes through the through hole and the sewage outlet. Two sets of rubber sleeves are fixed on the outside of the hanging pipe 302. The airbag 303, the two groups of rubber airbags 303 are respectively located on the upper and lower sides of the partition 105, the hanging pipe 302 is located in the two groups of rubber airbags 303 and the tube body is provided with a connecting hole 302a, the tube body of the hanging pipe 302 located above the cross bar 301 has an external thread and is threadedly connected with a limiting nut 304, the bottom of the limiting nut 304 is against the cross bar 301, and the top of the hanging pipe 302 is fixedly connected with a valve core 305, and the rubber airbag 303 is spherical and its size is larger than the size of the sewage outlet.

[0031] Among them, the waste flow well 101, the water inlet pipe 102 and the rainwater pipe 103 are all made of PE material, which is easy to process and has low processing cost. The waste flow well 101, the water inlet pipe 102 and the rainwater pipe 103 are integrally formed, and the integral forming can ensure the structural strength.

[0032] In addition, reinforcing ribs are provided on the outside of the waste well 101, and reinforcing ribs are provided on the outside of the water inlet pipe 102 and the rainwater pipe 103. The reinforcing ribs are used to improve the structural strength of the device. The waste pipe 104 is located close to the bottom of the waste well 101 to prevent sewage from remaining in the device. The water inlet pipe 102 and the rainwater pipe 103 have the same size specifications to ensure the drainage effect.

[0033] It should be noted that the partition 105, the filter plate 201, the top plate 202 and the cross bar 301 are all made of stainless steel, which is corrosion-resistant, and the hanging pipe 302 is made of aluminum alloy, which is corrosion-resistant and light.

[0034] Working principle: At the beginning of rain, the flow rate of the water inlet pipe 102 is less than the flow rate of the waste pipe 104. At this time, the rainwater flows to the bottom of the partition 105 through the sewage outlet of the partition 105, and is discharged into the sewage pipeline from the waste pipe 104. As the rain continues, the flow rate of the water inlet pipe 102 gradually increases. When the flow rate of the water inlet pipe 102 is greater than the flow rate of the waste pipe 104, the water level below the partition 105 gradually rises, and the rubber airbag 303 below the partition 105 floats up with the increase of the water level. When the rubber airbag 303 blocks the sewage outlet, the water level above the partition 105 gradually rises. The buoyancy of the rubber airbag 303 above the partition 105 and the rubber airbag 303 below always block the sewage outlet. At this time, the water flows through the filter orifice plate 201 and is discharged into the rainwater pipeline from the rainwater pipe 103. The water inlet pipe 102 filters impurities in the water flow.

[0035] When it is necessary to clean the rubber airbags 303, press the valve core 305 to deflate the two groups of rubber airbags 303, lift the hanging tube 302, and the rubber airbags 303 located below the partition 105 are lifted above the partition 105. At this time, the two groups of rubber airbags 303 can be cleaned. After cleaning, the rubber airbags 303 located below are lowered to the bottom of the partition 105, and the two groups of rubber airbags 303 are inflated through the valve core 305, and the device can continue to be used.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
