DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. It should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", and "set" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0027] Reference Figure 1-Figure 5 A sewer waste cleaning and recycling device includes a connecting pipe 1. The connecting pipe 1 serves as the main part of the entire device. One end of the connecting pipe is designed with an interface for connecting to an external water pump to provide the water flow required for flushing. The other end is designed as a detachable connection structure for installing a connecting head 2. The connecting head 2 is firmly connected to the connecting pipe 1 by threads or other fastening methods. A plurality of support pipes 3 are evenly distributed on its outer wall. One end of these support pipes 3 is communicated with the inside of the connecting pipe 1, and the other end is fixedly installed with a nozzle 9, which is used to evenly spray water onto the inner wall of the sewer during the flushing process to effectively clean up attachments.

[0028] In order to collect the flushed waste, a mounting ring 11 is detachably installed on the outer wall of the connecting pipe 1, and a filter disc 10 is sleeved on the mounting ring 11. A fixing ring 4 is fixed to the outer side of the filter disc 10 and the outer walls of multiple support tubes 3. The two fixing rings 4 are connected by a filter mesh 7 to form a closed or semi-closed collection frame. In this way, when the water flow carries waste through, most of the waste will be intercepted and collected by the filter mesh 7.

[0029] In order to achieve rapid installation and disassembly of the filter 7, a fixing mechanism is also provided: a plurality of second positioning posts 14 are fixedly provided on the outer side of one end of the filter 7, and a second positioning hole 15 is correspondingly opened at the other end. During installation, one end of the filter 7 is inserted into the second positioning hole 15 through the second positioning post 14 to achieve preliminary positioning. Subsequently, a plug rod 17 is inserted into the socket 16 opened on the side of each second positioning post 14. The filter 7 is further fixed by the insertion of the plug rod 17. For ease of operation, a connecting strip 18 is also fixedly connected to one side of the plurality of plug rods 17. The user can insert a plurality of plug rods 17 into the socket 16 at one time to improve installation efficiency. At the same time, the length of the connecting strip 18 is less than the spacing between the two fixing rings 4 to ensure that it will not interfere with the fixing ring 4 during operation.

[0030] In addition, two groups of first positioning holes 13 are opened on the outside of the filter screen 7, and first positioning columns 12 are inserted into the first positioning holes 13. The two fixing rings 4 are fixed with connecting rings 8 at one end close to each other. The two groups of the first positioning columns 12 are respectively fixed on the outside of the two connecting rings 8, which can fix the filter screen 7 on the fixing rings 4 and further improve the stability of the connection.

[0031] In addition, in order to improve the mobility of the device in the sewer and reduce frictional resistance, this embodiment also has multiple rollers 5 fixedly installed on the outside of the fixing ring 4. These rollers 5 are in contact with the inner wall of the sewer, which can help the device move forward or backward smoothly during the flushing process. A conical head 6 is provided at one end of the front fixing ring 4, so that its size is adapted to the inner diameter of the sewer, ensuring sealing and stability.

[0032] In order to further ensure the fixing effect of the filter screen 7, a nut ring 19 is threadedly sleeved on the outer wall of one of the second positioning columns 14. When the insertion rod 17 is inserted into the socket 16, the nut ring 19 is rotated to make it in close contact with the top of the connecting strip 18, thereby increasing the strength of the fixing point and preventing the filter screen 7 from loosening or falling off during the flushing process.

[0033] Working principle: When in use, put the device into the sewer, then connect one end of the connecting pipe 1 to the water pipe of the external water pump, then pass the pull rope through the sewer, and fix one end of the pull rope on the connector 2, and then start the external water pump. Water enters the connector 2 through the connecting pipe 1 and enters the nozzle 9 through the support pipe 3, and is sprayed out through the nozzle 9. At the same time, pull the pull rope to drive the device to move in the sewer. During the movement, the waste in the sewer passes through the cone head 6 and enters the filter screen 7, while the silt is filtered out through the filter holes;

[0034] After cleaning is completed, rotate the nut ring 19 to disengage the nut ring 19 from the second positioning column 14, and then push the connecting bar 18 to move. The movement of the connecting bar 18 can drive the insertion rod 17 to move until the insertion rod 17 disengages from the insertion hole 16, and then flip one end of the filter screen 7 outward to disengage the second positioning column 14 from the second positioning hole 15, and the first positioning column 12 from the first positioning hole 13, and finally take out the waste.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
