[0022] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0023] Example 1

[0024] The utility model provides a pipeline outer wall cleaning device, such as Figure 1 and Figure 2 As shown, it includes a dust box 2, an isolation chamber 3 is provided inside the dust box 2, a ventilation and heat dissipation window 14 connected to the outside of the dust box 2 is provided on the isolation chamber 3, an air inlet 5 connected to the inside of the dust box 2 is also provided on the isolation chamber 3, an induced draft fan 4 is provided inside the isolation chamber 3, a conical slow flow cover 6 is connected between the air inlet 5 and the input end of the induced draft fan 4, the large end of the slow flow cover 6 is close to the air inlet 5, and a filter screen 13 is covered on one side of the air inlet 5 located inside the dust box 2. A dust hood 8 is connected to the outside of the dust box 2 through a hose 7, and the connection position is located at the top of the hood body. A cleaning roller brush 12 is rotatably connected inside the dust hood 8, and a telescopic component 9 is fixed outside the dust hood 8.

[0025] like Figures 1 to 3 As shown, the telescopic assembly 9 includes an inner rod 92 connected to the dust hood 8 at one end, an outer tube 91 is coaxially sleeved on the other end of the inner rod 92, a fixing ring 93 is coaxially sleeved on the end of the outer tube 91 close to the dust hood 8, and a handle 97 is fixedly connected to the end of the outer tube 91 away from the dust hood 8. The fixing ring 93 is coaxially fixedly connected to a connecting ring 94 extending outward at one end close to the dust hood 8, the extending end opening of the connecting ring 94 is contracted inwardly into a cone and is evenly spaced along the circumference and is provided with a plurality of through grooves in the length direction. After the through grooves are provided, the connecting ring 94 is in a shape similar to an expansion bolt, the outer wall of the extending end of the connecting ring 94 is provided with an external thread and is threadedly connected to a positioning ring 95 located outside the connecting ring 94, and the outer wall of the positioning ring 95 is provided with anti-slip grooves 96.

[0026] like Figure 4 As shown, a partition 10 is arranged in the dust cover 8, a cleaning roller brush 12 is arranged on one side of the partition 10, and a motor 11 is arranged on the other side of the partition 10. The output shaft of the motor 11 passes through the partition 10 and is coaxially fixedly connected with the cleaning roller brush 12.

[0027] Through the above-mentioned method, the pipeline outer wall cleaning device of the utility model brushes off the dust and other impurities on the outer wall of the pipeline through the cleaning roller brush 12, and then sucks them into the dust collecting box 2 through the induced draft fan 4. The cleaning process is completed by the machine. During the operation process, personnel only need to move the dust hood 8, and pipelines at different heights can be cleaned. The cleaning effect is good, and the generated dust is easy to collect, which greatly improves efficiency and saves labor costs.

[0028] Example 2

[0029] The utility model provides a pipeline outer wall cleaning device. When in use, the motor 11 drives the cleaning roller brush 12 on the other side of the partition plate 10 to rotate, and the dust and other impurities on the pipeline outer wall are brushed off. At the same time, the induced draft fan 4 is started, and the air in the dust box 2 is sucked into the isolation chamber 3 through the air inlet 5 and the slow flow cover 6, and then discharged through the ventilation and heat dissipation window 14, so that the dust box 2 is in a negative pressure state. At this time, the high-speed airflow in the dust suction hood 8 carries the brushed impurities into the dust box 2 through the hose 7. After entering the dust box 2, the air flow cross-section is significantly increased, the air flow velocity is significantly slowed down, and the impurities fall into the dust box 2. The position of the air inlet 5 is also negative pressure due to the suction of the induced draft fan 4 and the input end cross-section of the induced draft fan 4 is small. If the input end of the induced draft fan 4 is directly connected, the air flow velocity at the position of the air inlet 5 will also increase, thereby introducing more dust and other impurities. At this time, the air flow cross-section at the position of the air inlet 5 is increased by the slow flow cover 6 to reduce the flow velocity. The larger area of ​​the filter 13 can also absorb more residual dust, thereby ensuring the suction effect and reducing the number of times the filter 13 is replaced. If you want to clean pipes at different heights, hold the anti-slip groove 96 and rotate the positioning ring 95 to loosen it from the connecting ring 94, so that the connecting ring 94 no longer clamps the inner rod 92. Then, extend the inner rod 92 from the outer tube 91 or further insert it to adjust the total length of the inner rod 92 and the outer tube 91. After completion, rotate the positioning ring 95 again to make the connecting ring 94 on the fixing ring 93 shrink and clamp the inner rod 92. Finally, hold the handle 97 to align the dust cover 8 with the outer wall of the pipe to be cleaned.

[0030] Example 3

[0031] The utility model provides a pipeline outer wall cleaning device, such as Figure 1 and Figure 2 As shown, a door 17 is provided on one side wall of the dust box 2, and a groove 18 is provided on the outside of the door 17. The door 17 is opened regularly through the groove 18 to clean the dust and other impurities that fall into the dust box 2, and to replace the filter 13. A handle 16 is fixed on the top of the dust box 2 to facilitate the placement and movement of the dust box 2. A base plate 1 is fixed to the bottom of the dust box 2, and a brake universal wheel 19 is provided under the base plate 1 to facilitate the movement and positioning of the dust box 2. A dustproof net 15 is covered inside the ventilation and heat dissipation window 14. The ventilation and heat dissipation window 14 can discharge the heat generated by the induced draft fan 4 when it is working while discharging the gas sucked by the induced draft fan 4 to maintain the air pressure. The dustproof net 15 effectively prevents dust from entering the isolation chamber 3.
