Description

Technical Field

[0001] The invention relates to the technical field of shaft maintenance, in particular to a dirt removal device for shaft cleaning. Background Art

[0002] As we all know, manholes refer to various types of sewers, such as rainwater wells, sewage wells, etc., which are mainly used in urban drainage, sewage and other systems. They play the role of pipeline connection and transfer, inspection and maintenance channels, dredging and cleaning pipelines, sedimentation and filtering impurities, etc. They are an important part of urban infrastructure. Various solid wastes, mud, grease and other dirt are often accumulated in the walls of manholes. These substances will gradually accumulate, affecting the drainage efficiency and even causing pipe blockage.

[0003] The problem with the prior art is that although anti-falling nets are usually installed in the manhole, this type of structure can not only protect personnel but also intercept some of the falling impurities and reduce the probability of them adhering to the manhole wall. However, after long-term use, sand and sticky impurities will still adhere to the manhole wall layer by layer, and usually cleaning is mostly done by spraying with a water gun. This method is not only difficult to remove stubborn dirt, but also has a limited spraying point of the water gun, so the efficiency needs to be improved.

[0004] Based on the above-mentioned situation, we found that it is difficult for the existing manhole cleaning device to avoid the above problems at the same time. Therefore, we proposed a dirt removal device for manhole cleaning that can be used in conjunction with brushing to clean the manhole, while improving cleaning efficiency and reducing labor consumption and operation difficulty. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides a dirt removal device for cleaning manholes, which has the advantages of being able to clean manholes in conjunction with brushing, while improving cleaning efficiency and reducing labor consumption and operating difficulty.

The bottom of the limiting cage 4 is connected to the cleaning component 6 through the lower frame 5, so the cleaning component 6 will also fall to different depths of the manhole for cleaning, thereby improving the cleaning efficiency.

[0044] Among them, a reduction motor 15 is fixedly connected to the top of the upper frame 1, and a pulley is installed on the outer side of the output end of the reduction motor 15. The transmission ring 3 and the pulley are connected through a transmission belt transmission. By setting the reduction motor 15, while cleaning, the reduction motor 15 drives the transmission ring 3 to rotate through the pulley, and the transmission ring 3 rotates along the upper frame 1 through the bottom slip ring 2 so that the cleaning area can cover the entire inside of the shaft.

By setting the limiting cage 4 and the suspension 16 made of annular pipes, it is possible to avoid damage caused by bending or entanglement of the hose when the structure rotates. The bottom of the suspension 16 is fixedly connected with a surrounding frame 19, and the inner side of the surrounding frame 19 is slidably connected to the outer side of the top of the limiting cage 4. By setting the surrounding frame 19, it is convenient to connect the suspension 16 and the limiting cage 4, and at the same time, the limiting cage 4 can be rotated along the surrounding frame 19, which has a limiting effect on the structure.

[0045] Working principle of this embodiment: First, place the upper frame 1 on the ground at the wellhead of the Yin shaft, so that the cleaning assembly 6 falls into the Yin shaft. When it is necessary to clean the inner wall of the Yin shaft at different vertical heights, control the telescopic end of the telescopic cylinder 7 to retract or extend. Since the telescopic end of the telescopic cylinder 7 is movably connected with the limit cage 4, the limit cage 4 will rise or fall in the vertical direction. Since the bottom of the limit cage 4 is connected with the cleaning assembly 6 through the lower frame 5, the cleaning assembly 6 will reach different depths of the Yin shaft, and prepare for cleaning the dirt on the inner wall at different heights. Start the reduction motor 15, and the pulley on the outer side of its output end moves with it. As the upper frame 1 rotates, the pulley drives the transmission ring 3 to rotate through the transmission belt. The transmission ring 3 and the slip ring 2 are formed in one piece. The slip ring 2 will rotate along the inner side of the upper frame 1. Since the inner side of the slip ring 2 is slidingly connected with the limiting cage 4, and the limiting cage 4 is connected with the cleaning component 6 through the lower frame 5, the cleaning component 6 will rotate accordingly, so that the cleaning area can cover the entire interior of the well. The cleaning pump 17 is started, and the cleaning water enters the hose from the output end of the cleaning pump 17, and is then transported to the inside of the cleaning pipe 609 through the rotating joint 18, and finally sprayed to the inner wall of the well by the cleaning nozzle outside the cleaning pipe 609 to assist in cleaning dirt.

[0046] Example 2

[0047] refer to Figure 1-7A dirt removal device for cleaning a yin well also includes a cleaning assembly 6, wherein the cleaning assembly 6 includes a broken frame 601, the inner side of the broken frame 601 is rotatably connected to an adjustment frame 602, the top of the adjustment frame 602 is fixedly connected to a cleaning motor 603, the output end of the cleaning motor 603 passes through the adjustment frame 602 and is fixedly connected to a brush shaft 604, a cleaning brush 605 is installed on the outer side of the brush shaft 604, the outer side of the adjustment frame 602 is fixedly connected to a side frame 606, the side frame 606 and the bottom of the brush shaft 604 are rotatably connected, the inner side of the broken frame 601 is fixedly connected to a crossbeam 607, the bottom of the crossbeam 607 is provided with a push frame 608, the outer side of the push frame 608 is movably connected to the side frame 606, a cleaning pipe 609 is installed on the inner side of the crossbeam 607, and a cleaning nozzle is installed on the outer side of the cleaning pipe 609;

[0048] By setting the upper frame 1 to be placed on the ground when in use, and making the cleaning component 6 fall into the inner wall of the well, and then adjusting the opening of the side frame 606 according to the inner diameter of the well, while controlling the vertical movement of the push frame 608, the side frame 606 connected thereto will also be pressed, and the frame 602 will be adjusted to deflect along the broken frame 601 at an angle. When multiple side frames 606 are opened at the same time, the cleaning brush 605 outside the brush shaft 604 will also approach and contact the inner wall of the well until it is in a position convenient for cleaning, and then water is supplied to the inside of the cleaning pipe 609, and the cleaning water is sprayed to the inner wall of the well through the cleaning nozzle for flushing. At the same time, the brush shaft 604 is driven to rotate by the cleaning motor 603, and the cleaning brush 605 outside it will also rotate and brush the inner wall of the well. Compared with just flushing, it has a stronger ability to peel off stubborn dirt and covers a larger area, which effectively improves the cleaning efficiency.

[0049] Among them, the side frame 606 is fixedly connected with a guide rail 8 on the side close to the push frame 608, and a slider 9 is slidably connected to the inner side of the guide rail 8. The outer side of the slider 9 is fixedly connected with a rotating shaft 10. The side of the rotating shaft 10 close to the push frame 608 is fixedly connected to the push frame 608. The guide rail 8 is provided to cooperate with the slider 9 to connect the side frame 606 and the push frame 608, and at the same time, when the push frame 608 pushes and pulls the side frame 606, the structure is prevented from being stuck and unable to be used normally. The top of the crossbeam 607 is fixedly connected with an adjustable The output end of the motor 11 passes through the cross beam 607 and is fixedly connected to the screw rod 12. The bottom of the screw rod 12 is fixedly connected to the bottom plate 13. The outer side of the screw rod 12 is fixedly connected to the push frame 608. The bottom of the cleaning tube 609 is fixedly connected to the bottom plate 13. By setting the adjustment motor 11, when it is necessary to adjust the vertical height of the push frame 608, the transmission direction of the screw rod 12 for the push frame 608 can be adjusted by controlling the adjustment motor 11 to rotate forward or reverse, thereby adjusting the vertical lifting of the push frame 608. The top of the bottom plate 13 is fixedly connected to the limiting column 14, the outer side of the limiting column 14 is movably connected to the push frame 608, and the top of the limiting column 14 is fixedly connected to the crossbeam 607. By setting the limiting column 14, the push frame 608 can be easily limited when it moves vertically to avoid rotation or tilting and causing it to be unable to be used normally.

The inner side of the threaded block 21 is threadedly connected to the screw rod 12. By setting an eccentric frame 20 to cooperate with the threaded block 21, the eccentric frame 20 is used to cooperate with the threaded block 21 to lift the push frame 608 when the screw rod 12 is transmitted to the inner side of the threaded block 21. The inner side of the eccentric frame 20 is slidably connected to the limit column 14. The eccentric frame 20 is arranged on the outer side of the cleaning tube 609. By setting the limit column 14 and the eccentric frame 20, the vertical limit of the push frame 608 during movement can be reasonably performed. The setting of the eccentric frame 20 can prevent the push frame 608 from affecting the normal movement of the cleaning tube 609 during movement.

Since the screw rod 12 is threadedly connected to the push frame 608 through the threaded block 21 on the eccentric frame 20, the push frame 608 will move vertically when the screw rod 12 rotates. When the push frame 608 moves vertically, the sliding cooperation of the rotating shaft 10 and the slider 9 in the guide rail 8 presses against the side frame 606 connected thereto, and the side frame 606 is deflected along the broken frame 601 through the adjusting frame 602, so that multiple side frames 606 are opened at the same time, thereby making the brush shaft 60 The cleaning brush 605 on the outside approaches and contacts the inner wall of the yin shaft until it reaches a position convenient for cleaning. During this process, the limiting column 14 limits the push frame 608 to prevent it from rotating or tilting, thereby ensuring the normal operation of the structure; the eccentric frame 20 cooperates with the screw rod 12 to realize the lifting and lowering of the push frame 608, and avoids affecting the normal activity of the cleaning pipe 609. After water is supplied to the inside of the cleaning pipe 609, the cleaning water is sprayed to the inner wall of the yin shaft through the cleaning nozzle installed on the outside of the cleaning pipe 609 to perform a preliminary flushing of the inner wall.
