Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to a drainage pipe capable of preventing foreign matter from accumulating. Background Art

[0002] Municipal drainage pipes refer to the rainwater and sewage pipes under municipal roads, commonly known as "sewer pipes". Rainwater is generally discharged into the nearest river, and sewage is discharged into the sewage treatment plant. Rainwater washes down a lot of debris, usually mixed with plastic bags, paper scraps, leaves, mud and sand, etc. Rainwater mixed with debris is discharged into the municipal drainage pipe.

[0003] The accumulation of debris reduces the water-passing cross-section of municipal drainage pipes and weakens their drainage capacity, which can easily cause road waterlogging and urban waterlogging. Therefore, it is necessary to prevent drainage pipes from accumulating foreign matter. At the same time, long-term use will also cause damage to the filter mechanism, which needs to be replaced to ensure the normal use of the filter mechanism. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] According to a first aspect of the utility model, a drainage pipe capable of preventing accumulation of foreign matter comprises:

[0007] A mounting pipe, wherein the outer longitudinal section of the mounting pipe is rectangular, and the inner longitudinal section of the mounting pipe is circular, and a connecting pipe is installed at the outer end of the mounting pipe for connecting with a conventional pipeline;

[0008] A filter screen is installed on the inner side of the installation tube, and the upper end of the filter screen is detachably connected to the outer side of the installation tube by bolts;

[0009] A guide ring is fixed at the lower end of the installation tube, and a collecting groove is installed at the lower end of the guide ring, and the guide ring is arranged in an inclined manner.

[0010] Furthermore, the filter screen is arranged at an angle.

[0011] Furthermore, a support block fixed in the mounting tube is arranged on the right side of the filter screen, and a groove structure opened in the mounting tube is arranged at the lower end of the filter screen, and the filter screen and the groove structure form a snap-fit ​​connection.

[0012] Furthermore, a backwash mechanism is installed on the rear side of the mounting pipe, and the backwash mechanism includes a flushing pipe, a water inlet pipe is installed at the rear end of the flushing pipe, a fixing ring is installed on the outside of the flushing pipe, and a compensating ring which is also installed on the outside of the flushing pipe is provided on the front side of the fixing ring.

[0013] Furthermore, a sealing ring structure is installed on the rear side of the compensation ring.

[0014] Furthermore, the fixing ring and the flushing pipe form a detachable connection.

[0015] The utility model has the following advantages:

[0016] 1. The filter and the installation pipe form a detachable connection, which facilitates the replacement of the filter and ensures the normal function of the filter;

[0017] 2. By setting the guide ring at an angle, foreign matter and impurities can be guided into the guide ring, and the water flow guided in can be dispersed, reducing the loosening of the collection tank caused by the impact of the water flow. At the same time, it can prevent the foreign matter and impurities on the inside of the collection tank from being lifted up when the water flow enters, thereby causing a burden on the filter screen, thereby preventing foreign matter from accumulating in the installation pipe.

[0023] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0024] like Figures 1 to 4 As shown, a drainage pipe capable of preventing the accumulation of foreign matter in the first embodiment of the utility model comprises a mounting pipe 1, the outer longitudinal section of the mounting pipe 1 is rectangular, and the inner longitudinal section of the mounting pipe 1 is circular, which reduces the need for special-shaped parts and facilitates installation with conventional parts. A connecting pipe 2 is installed at the outer end of the mounting pipe 1 for connecting with conventional pipelines;

[0025] A filter screen 3 is installed on the inner side of the mounting tube 1, and the upper end of the filter screen 3 is detachably connected to the outer side of the mounting tube 1 by bolts, which is convenient for replacing the filter screen 3. The filter screen 3 is arranged at an angle to avoid being directly impacted by water flow. A support block 5 fixed in the mounting tube 1 is arranged on the right side of the filter screen 3, and a groove structure opened in the mounting tube 1 is arranged at the lower end of the filter screen 3, and the filter screen 3 is engaged with the groove structure, which can support the rear side of the filter screen 3 to avoid tilting.

[0026] A guide ring 6 is fixed to the lower end of the mounting tube 1, and a collecting groove 7 is installed at the lower end of the guide ring 6. The guide ring 6 is inclined to disperse the water flow guided in, reduce the loosening of the collecting groove 7 caused by the impact of the water flow, and prevent the foreign matter and impurities inside the collecting groove 7 from being lifted up when the water flow enters, thereby causing a burden on the filter screen 3, thereby preventing foreign matter from accumulating in the mounting tube 1. Example

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a drain pipe that can prevent the accumulation of foreign matter includes all the contents of Example 1. In addition, a backwashing mechanism 4 is also installed on the rear side of the mounting pipe 1, and the backwashing mechanism 4 includes a flushing pipe 401. A water inlet pipe 402 is installed at the rear end of the flushing pipe 401, and a fixing ring 403 is installed on the outer side of the flushing pipe 401, and a compensating ring 404 which is also installed on the outer side of the flushing pipe 401 is provided on the front side of the fixing ring 403. A sealing ring structure is installed on the rear side of the compensating ring 404, which can supplement the gap between the flushing pipe 401 and the mounting pipe 1 when not working, thereby reducing the possibility of water leakage. The fixing ring 403 is detachably connected to the flushing pipe 401 to reinforce the fixing ring 403 to adapt to the impact of the backwashing mechanism 4 when it derives water flow.

[0028] The technical effect achieved by the above embodiment is: the water inlet pipe 402 is opened, so that the flushing pipe 401 can output water to backwash the filter 3, and the impurities attached to the surface of the filter 3 are flushed to avoid affecting the filtering effect of the filter 3.
