[0029] The device can clean the sludge on the inner wall of the urban pipeline by steam. The high temperature and pressure of the steam can effectively soften and remove the sludge on the inner wall of the pipeline, thereby improving the silt removal efficiency. The steam generator, steam delivery pump, water pump, sludge suction pump and pusher used in the device are all existing mature technologies, and their structure and use method are not specifically described in this article;

[0030] When working, the device is placed on the inner wall of the city pipeline, the supporting mechanism is used to make the device contact with the inner wall of the pipeline, and the pusher is used to make the device move on the inner wall of the pipeline to achieve mobile cleaning. In the process of cleaning the inner wall of the pipeline, steam is produced by the steam generator, and is transported by the steam delivery pump. The produced steam is transported through the steam delivery pipe 18. During the transportation process, the steam passes through the connecting valve 17 and the steam delivery pipe 16 in sequence until it reaches the inner side of the steam release box 14, and the steam is burst out through the air vent 15 to achieve cleaning. The sludge on the inner wall of the pipeline is softened and removed. At the same time, the cleaning mechanism arranged at the rear thereof scrapes the sludge on the inner wall of the pipeline. The scraped sludge is guided to the inner side of the dredging pipe body 23 through the cleaning mechanism. As the sludge increases, the sludge enters the inner side of the mud suction pipe 23, and then the sludge is pumped out by the sludge suction pump. After the cleaning mechanism cleans the sludge, the clean water is pumped to the inner side of the water pipe 1 19 through the water pump. The clean water enters the interior of the nozzle 21 through the water pipe 1 19 and the water pipe 2 22 in turn, and the inner wall of the pipeline is washed through the nozzle 21.

[0031] In the device, two groups of support mechanisms are provided, located at the front and rear ends of the device, so as to maintain sufficient balance during the cleaning of the inner wall of the pipeline;

[0032] In the present device, two groups of cleaning mechanisms are also provided. When the present device is pushed forward, one group of cleaning mechanisms is controlled to move downward, and the other group of cleaning mechanisms is controlled to move upward until it fits with the inner wall of the pipe, so that the present device can guide the scraped sludge to the inner side of the two groups of cleaning mechanisms during the process of cleaning the sludge. After the sludge enters the inner side of the two groups of cleaning mechanisms, it enters the inner side of the connecting rod 2. As the present device is continuously pushed forward by the pusher, the sludge continues to increase, and the sludge enters the inner side of the dredging pipe body 2 3 and is discharged through the mud suction pipe 23.

[0033] When the device is pushed backward, the upward and downward directions of the two sets of cleaning mechanisms are opposite to each other, so as to prevent omissions during use of the device, and when encountering a pipe part that cannot be cleaned at one time, the device can be controlled to repeatedly clean the same position.

[0034] Further, such as Figure 1 and Figure 4As shown, the cleaning mechanism includes a plurality of hinged seats 5 installed on the loading hoop 4, the tops of the plurality of hinged seats 5 are fixedly installed with electric spring rods 6, and the ends of the plurality of electric spring rods 6 away from the hinged seats 5 are fixedly installed with scrapers 7, and a notch 32 is provided on the scraper 7;

[0035] During operation, the cleaning mechanism is fixed on the dredging pipe body 1 and the dredging pipe body 2 3 respectively through the loading hoop 4, and the electric spring rod 6 can be rotated through the hinge seat 1 5 to adapt to the angle change range of the cleaning mechanism when it moves up and down. The electric spring rod 6 can drive the scraper 7 to move up and down, and the notch 32 is convenient for adapting to the bending caused by the expansion and contraction of the scraper 7 when it moves up and down. Since the scraper 7 is in a circular ring shape, the above-mentioned up and down movement is the outward expansion and inward contraction of the scraper 7.

[0036] Further, such as Figure 6 As shown, a steel cord 8 is embedded inside the scraper blade 7;

[0037] During operation, when the electric spring rod 6 drives the scraper 7 to move up and down, the steel cord 8 is equivalent to adding a layer of wire mesh-like structure in the scraper 7 to fix the inside of the scraper 7 to avoid displacement or damage, thereby improving the strength and stability of the scraper 7. The steel cord 8 can withstand the internal and external forces when the scraper 7 is deformed, limit its deformation, and maintain dimensional stability.

[0038] Further, such as Figure 4 and Figure 5 As shown, a clamping groove 1 9 is provided on the inner side of the scraper blade 7, and a clamping groove 2 10 is provided on the inner side of the loading hoop 4. The clamping groove 1 9 and the clamping groove 2 10 are both ring-shaped, and an anti-overflow pad 11 is clamped on the inner side of the clamping groove 1 9 and the clamping groove 2 10;

[0039] During operation, the anti-overflow pad 11 is installed through the snap-in groove 2 10 and the snap-in groove 1 9. The anti-overflow pad 11 and the scraper blade 7 in the device are both made of rubber. The anti-overflow pad 11 can ensure that the silt can fall into the inner side of the dredging pipe body 1, the connecting rod 2 and the dredging pipe body 2 3 during the process of moving forward or backward, so as to prevent the silt from overflowing.

[0040] Further, such as Figure 2 As shown, a plurality of connectors 24 are fixedly provided on the mud suction pipe 23;

[0041] During operation, when the device is sucking sludge, the connector 24 on the sludge suction pipe 23 can be connected to the pipeline on the sludge suction pump.

[0042] Further, such as Figure 2As shown, a hinge seat 2 12 is fixedly installed on the back of the plurality of scrapers 7, a support frame 13 is hinged on the hinge seat 2 12, and one end of the plurality of support frames 13 away from the hinge seat 2 12 is fixedly connected to the dredging pipe body 1 and the dredging pipe body 2 3 respectively;

[0043] During operation, the hinged seat 2 12 is used to fix the support frame 13, and the cooperation between the two ensures that the scraper 7 maintains sufficient stability during the cleaning process.

[0044] Further, such as Figure 3 As shown, a connecting valve 17 is also provided on the inner side of the desilting pipe body 1, a plurality of steam delivery pipes 16 are connected through the connecting valve 17, and a steam delivery pipe 2 18 is connected to the connecting valve 17;

[0045] During operation, when the device is cleaning the sludge on the inner wall of the pipeline, the steam delivery pipe 16 and the steam delivery pipe 2 18 can be connected through the connecting valve 17 to facilitate the delivery of steam. The multiple steam delivery pipes 16 connected by the connecting valve 17 can enable multiple steam release boxes 14 and air holes 15 to burst out steam at the same time, thereby expanding the scope of steam cleaning.

[0046] Further, such as Figure 2 As shown, water pipe 22 extends to the inner side of the protective pipe 20 and is connected to water pipe 19; during operation, after the device completes the sludge cleaning action on the pipeline, the inner wall of the pipeline can be cleaned with clean water through the nozzle 21, and the water pump pumps the liquid into water pipe 19, and then transports it to water pipe 22 through water pipe 19, and the liquid is ejected through water pipe 22. In addition, water pipe 19 can also be used to transport anti-corrosion liquid to perform anti-corrosion treatment on the inner wall of the pipeline to extend the service life of the pipeline. The remaining structures of the device can also be used for efficient cleaning of the pipeline before anti-corrosion.

[0047] Further, such as Figure 7 As shown, the support mechanism includes a fixing frame 25 fixedly arranged on both the desilting pipe body 1 and the desilting pipe body 2 3, a hinge seat 29 fixedly installed on the fixing frame 25, an electric push rod 30 hingedly arranged on the hinge seat 29, a through hole 31 is opened on the fixing frame 25 and located above the hinge seat 29, the electric push rod 30 penetrates the through hole 31, an adapter frame 26 is hingedly arranged on the top of the fixing frame 25, a hinge seat 3 28 is fixedly installed on the adapter frame 26, the hinge seat 3 28 is connected to the electric push rod 30, and a roller 27 is also fixedly arranged on the adapter frame 26;

[0048] When working, two groups of support mechanisms are provided, which are located at the front and rear ends of the device. In the process of cleaning the inner wall of the pipeline, sufficient balance can be maintained. The fixed frame 25 is used to load the articulated seat four 29 and the adapter frame 26. The articulation between the fixed frame 25 and the adapter frame 26 can realize the adaptive pipe diameter. The expansion and contraction between the fixed frame 25 and the adapter frame 26 can be realized by extending and contracting the electric push rod 30 articulated between the articulated seat three 28 and the articulated seat four 29. The roller 27 can facilitate the movement of the device and the inner wall of the pipeline.
