DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figures 1 to 4As shown, a drain pipe dredging device described in an embodiment of the utility model comprises a dredging head 1; a cavity is provided inside the dredging head 1; a plurality of first slots 12 are provided on the side wall of the dredging head 1; a first nozzle 13 is fixedly connected to the side wall of the first slot 12; a second slot 14 is provided on the left side wall of the dredging head 1; a second nozzle 15 is fixedly connected to the end of the second slot 14; a third slot 16 is provided on the right side wall of the dredging head 1; a pipe 17 is fixedly connected to the side wall of the third slot 16; a plurality of telescopic rods 18 are fixedly connected to the side wall of the pipe 17; a cavity is provided inside the telescopic rod 18; a spring 19 is fixedly connected to the inner side wall of the telescopic rod 18; an arc plate 110 is fixedly connected to the output end of the telescopic rod 18; a plurality of fourth slots 111 are provided on the top of the arc plate 110; a roller 112 is rotatably connected to the inner side wall of the fourth slot 111; a roller 113 is fixedly connected to the side wall of the roller 112. When working, first put the dredging head 1 into the drain pipe. When entering the drain pipe, the spring 19 is compressed by external force, so that the telescopic rod 18 shrinks downward, so that the arc plate 110 fits with the inner wall of the drain pipe, and then the roller 113 rolls on the inner wall of the drain pipe, so that the dredging head 1 can move forward, and then the water pump is connected to one end of the pipe 17, and then the liquid enters the dredging head 1 along the pipe 17, and is sprayed from the first nozzle 13 and the second nozzle 15, so that impurities can be separated from the inner wall of the drain pipe, which can play a role in dredging the drain pipe. By compressing the spring 19, the arc plate 110 fits with the inner wall of the drain pipe, and the dredging head 1 can be fixed, so that the dredging head 1 always moves forward in the middle of the drain pipe, reducing the problem that the dredging head 1 cannot move straight forward in the middle of the drain pipe due to the deviation caused by the spraying of water from the first nozzle 13 and the second nozzle 15.
[0025] like Figures 1 to 4 As shown, the side wall of the arc plate 110 is fixedly connected with a scraper 2; the scraper 2 is triangular in shape. When working, when the roller 113 rolls on the inner wall of the drain pipe, the scraper 2 moves forward to scrape off some impurities in the drain pipe. By moving the scraper 2 forward and scraping off some fiber tissues in the drain pipe, the adhesion of impurities inside the pipe 17 can be reduced.
[0026] like Figure 1 to Figure 2 As shown, the left wall of the dredging head 1 is fixedly connected to a support frame 3; the other end of the support frame 3 is fixedly connected to a scraper ring 31. When working, the scraper ring 31 cuts off some impurities in front of the second nozzle 15, and then the second nozzle 15 sprays liquid to remove the impurities, allowing the dredging head 1 to move forward faster. By cutting off some impurities in front of the second nozzle 15 with the scraper ring 31, the effect of clearing impurities in the drain pipe can be enhanced, and the blockage problem caused by impurities entangled at the end of the second nozzle 15 can be reduced.
[0027] like Figure 1 and Figure 5As shown, the side wall of the pipe 17 is fixedly connected with a plurality of first elastic rods 4; the side wall of the pipe 17 is fixedly connected with a plurality of second elastic rods 41; the other end of the first elastic rod 4 is fixedly connected with a metal wire 42; the other end of the metal wire 42 is connected with the second elastic rod 41. During operation, liquid is sprayed through the first nozzle 13 and the second nozzle 15 to separate impurities from the inner wall of the drain pipe. When these impurities pass through the first elastic rod 4, the first elastic rod 4 and the second elastic rod 41 will bend downward, reducing the direct contact between the impurities and the pipe 17, and at the same time, these impurities can be discharged. By bending the first elastic rod 4 and the second elastic rod 41 downward, the contact between the impurities and the pipe 17 can be reduced, thereby reducing the problem of impurities colliding with the pipe 17 and causing damage to the pipe 17.
[0028] like Figure 1 and Figure 5 As shown, a plurality of first elastic frames 5 are fixedly connected to the top of the metal wire 42; a plurality of second elastic frames 51 are fixedly connected to the top of the metal wire 42; and the side walls of the first elastic frames 5 fit the side walls of the second elastic frames 51. During operation, when impurities are discharged outward through the first elastic frames 5, the first elastic frames 5 will be bent so that the impurities can be discharged outward, and then the original position can be restored after the impurities are discharged, thereby preventing the impurities from flowing back. By bending the first elastic frame 5 and the second elastic frame 51 to discharge the impurities outward and restoring the first elastic frame 5 and the second elastic frame 51 to their original positions after the impurities are discharged, the metal wire 42 can be supported, and the problem of impurity backflow can be reduced.
[0029] like Figure 1 As shown, a column 6 is fixedly connected to the side wall of the pipe 17; the column 6 is on the left side of the telescopic rod 18. When working, the liquid sprayed from the first nozzle 13 and the second nozzle 15 will be diverted when passing through the column 6, so that the liquid bypasses the telescopic rod 18. Diverting the liquid through the column 6 can buffer the speed of the water flow, reduce the impact of the water flow on the telescopic rod 18, and reduce the problem of damage to the telescopic rod 18.
[0030] Working principle: First, put the dredging head 1 into the drain pipe. When entering the drain pipe, the spring 19 is compressed by external force, so that the telescopic rod 18 shrinks downward, so that the arc plate 110 can fit with the inner wall of the drain pipe, and then the roller 113 rolls on the inner wall of the drain pipe, so that the dredging head 1 can move forward, and then the water pump is connected to one end of the pipe 17, and then the liquid enters the dredging head 1 along the pipe 17, and sprays out from the first nozzle 13 and the second nozzle 15, so that impurities can be separated from the inner wall of the drain pipe, which can play the role of dredging the drain pipe. Through the compression of the spring 19, the arc plate 110 fits with the inner wall of the drain pipe, and the dredging head 1 can be fixed, so that the dredging head 1 always moves forward in the middle of the drain pipe, reducing the deviation of the dredging head 1 caused by the spraying of water from the first nozzle 13 and the second nozzle 15, and the problem that the dredging head 1 cannot move straight forward in the middle of the drain pipe. When the roller 113 rolls on the inner wall of the drain pipe, the scraper 2 moves forward to scrape off some impurities in the drain pipe. By moving the scraper 2 forward and scraping off some fibrous tissues in the drain pipe, the adhesion of impurities inside the pipe can be reduced. The scraper ring 31 cuts off some impurities in front of the second nozzle 15, and then the second nozzle 15 sprays liquid to remove the impurities, allowing the dredging head 1 to move forward faster. By cutting off some impurities in front of the second nozzle 15 by the scraper ring 31, the effect of clearing impurities in the drain pipe can be enhanced, and the blockage problem caused by impurities entangled at the end of the second nozzle 15 can be reduced. Liquid is sprayed through the first nozzle 13 and the second nozzle 15 to separate the impurities from the inner wall of the drain pipe. When these impurities pass through the first elastic rod 4, the first elastic rod 4 and the second elastic rod 41 will bend downward, reducing the direct contact between the impurities and the pipe 17, and at the same time, these impurities can be discharged. By bending the first elastic rod 4 and the second elastic rod 41 downward, the contact between the impurities and the pipe 17 can be reduced, thereby reducing the problem of impurities colliding with the pipe 17 and causing damage to the pipe 17. When the impurities are discharged outward through the first elastic frame 5, the first elastic frame 5 will be bent so that the impurities can be discharged outward, and then it will return to its original position after the impurities are discharged, which can prevent the impurities from flowing back. By bending the first elastic frame 5 and the second elastic frame 51 to discharge the impurities outward and returning the first elastic frame 5 and the second elastic frame 51 to their original positions after the impurities are discharged, the metal wire 42 can be supported and the problem of impurity backflow can be reduced. When the liquid sprayed from the first nozzle 13 and the second nozzle 15 passes through the column 6, the liquid will be diverted so that the liquid bypasses the telescopic rod 18. Diverting the liquid through the column 6 can buffer the speed of the water flow and reduce the impact of the water flow on the telescopic rod 18, which may cause damage to the telescopic rod 18.
