Description

Technical Field

[0001] This invention relates to the field of municipal engineering technology, specifically to a pipe cleaning device for road drainage in municipal engineering. Background Technology

[0002] Municipal engineering refers to the construction of municipal infrastructure. Drainage pipe cleaning equipment refers to the process of inserting a cleaning pipe into the pipe to be cleaned and cleaning the drainage pipe to remove accumulated debris and restore the pipe to its original state.

[0003] After the cleaning pipe is inserted into the pipe to be cleaned, various impurities easily adhere to the surface of the cleaning pipe. Workers usually perform simple cleaning by rinsing with water, which not only wastes water resources, but also makes it difficult to rinse off the impurities adhering to the surface of the cleaning pipe, affecting the appearance of the cleaning pipe and failing to meet the cleanliness requirements of municipal installations. If it is washed by hand, it is time-consuming and laborious. Summary of the Invention

[0018] This invention provides a pipe cleaning device for municipal engineering road drainage. It has the following beneficial effects:

[0019] (1) The municipal engineering road drainage pipe cleaning device can pre-treat the surface of the cleaning pipe by scraping, rinsing and wiping through the pipe surface cleaning device, and then absorb the residual water of the cleaning pipe through the second sponge block and the third sponge block. The whole process saves water and cleans completely.

[0020] (2) The municipal engineering road drainage pipe cleaning device uses a pipe surface pretreatment mechanism. The elastic scraper scrapes away most of the impurities on the outside of the cleaning pipe and its groove. The water in the first semi-circular plate falls through the water outlet to rinse the elastic scraper and wash away the remaining impurities on the elastic scraper, keeping the elastic scraper clean. After scraping, the cleaning pipe passes through the rinsing component. The sprayed water rinses the cleaning pipe, causing some of the remaining impurities in the cleaning pipe to slide off. After rinsing, the cleaning pipe passes through the water absorption component. The inner diameter of the first sponge block is slightly smaller than the diameter of the cleaning pipe. The first sponge block absorbs the water remaining on the cleaning pipe and wipes away some of the impurities in the cleaning pipe. Through the three-step pretreatment of scraping, rinsing and wiping, most of the impurities on the outside of the cleaning pipe are initially cleaned.

[0021] (3) The municipal engineering road drainage pipe cleaning device controls the movement of the second and third sponge blocks through the wiping mechanism and the switch of the pneumatic hydraulic pump. When the two second sponge blocks approach to form a ring, the third sponge block separates and removes the water. When the two third sponge blocks approach to form a ring, the second sponge blocks separate and remove the water. The second and third sponge blocks absorb water in a staggered manner, which can complete both water removal and water absorption.

[0022] (4) The municipal engineering road drainage pipe cleaning device uses a pipe surface pretreatment mechanism and a wiping mechanism. The pipe surface pretreatment mechanism can scrape off and rinse away the impurities adhering to the surface and groove of the cleaning pipe. However, the residual water on the pipe surface is difficult to clean completely. The wiping mechanism uses a second sponge block and a third sponge block to wipe and absorb the residual water on the surface and groove of the cleaning pipe in turn. Attached Figure Description

A water-absorbing sheet 525 passes through an arc-shaped hole 529 and is fixedly connected to the side of the second sponge block 523 near the axis of the cleaning pipe 4. A fourth circular hole 10 is opened through the middle of the second sponge block 523. A first squeezing plate 522 is provided between the pneumatic hydraulic pump 521 and the second sponge block 523. A support plate 7 is fixedly connected to the bottom of the first squeezing plate 522. The bottom of the support plate 7 is fixedly connected to the top of the water tank 2. A piston rod 9 passes through the interior of the first squeezing plate 522 and the fourth circular hole 10 in sequence and is slidably connected to the interior of the first squeezing plate 522 and the interior of the fourth circular hole 10. A connecting strip 526 is fixedly connected to the side of the piston rod 9. An L-rod 8 is fixedly connected to the bottom of the connecting strip 526.

The L-rod 8 passes through the interior of the second squeezing plate 527 and the third sponge block 528 and is slidably connected to the interior of the second squeezing plate 527 and the third sponge block 528.

[0051] In use, the pneumatic hydraulic pump 521 is started. The piston rod 9 moves sequentially along the axis of the cleaning pipe 4, carrying the second sponge block 523, the extrusion arc plate 524, and the water-absorbing sheet 525. The water-absorbing sheet 525 presses down on the cleaning pipe 4 and absorbs the last remaining moisture on its surface, preventing dust from the air from adhering to the side of the cleaning pipe 4. At the same time, the piston rod 9 moves sequentially along the axis away from the cleaning pipe 4, carrying the connecting bar 526, the third sponge block 528 and its extrusion arc plate 524, and the water-absorbing sheet 525. The third sponge block 528 presses tightly against the second extrusion plate 527, squeezing out the water from the third sponge block 528 and maintaining its water absorption capacity. The pneumatic hydraulic pump 521 is then turned off. 21. The second sponge block 523 presses tightly against the first squeezing plate 522, squeezing out the water from the second sponge block 523. The absorbent sheets 525 on the two third sponge blocks 528 move closer and contact the surface of the cleaning pipe 4 to absorb water. The movement of the second sponge block 523 and the third sponge block 528 is controlled by the switch of the pneumatic hydraulic pump 521. When the two second sponge blocks 523 approach to form a ring, the third sponge block 528 separates and removes the water. When the two third sponge blocks 528 approach to form a ring, the second sponge block 523 separates and removes the water. The second sponge block 523 and the third sponge block 528 absorb water in a staggered manner, which can complete both water removal and water absorption.
