Problems solved by technology

[0003] After a long time of use, dust is easy to accumulate in the corrugated gaps of the bellows. When there is a lot of dust, it will affect the expansion and contraction effect of the bellows, reducing the expansion and contraction range of the bellows, and the exposed bellows will affect the appearance after accumulating dust. , in some special occasions, the cleanliness of parts (such as bellows) is required to be high, so the bellows need to be cleaned. In the existing life, the bellows are generally cleaned manually with a brush, etc., and the cleaning effect is average. , and the cleaning efficiency is low

Embodiment 1

[0042] see Figure 1-6 , a bellows for easy cleaning of gaps between lines, comprising a bellows main body 1, the outer end of the bellows main body 1 is sleeved with a cleaning main ring 2, and the upper and lower ends of the cleaning main ring 2 are meshed with a power box 4, and the cleaning The outer side of the main ring 2 is provided with a cleaning secondary ring 3, and both ends of the cleaning secondary ring 3 are drilled with movable holes, a distance adjustment device 5 is connected between the power box 4 and the movable hole, and the inner end of the cleaning secondary ring 3 is fixedly connected with a A plurality of dust suction secondary pipes 6, the end of the cleaning secondary ring 3 away from the dust suction secondary pipe 6 is fixedly connected with a dust suction main pipe 7, and the dust suction secondary pipe 6, the cleaning secondary ring 3 and the dust suction main pipe 7 are connected in sequence.

[0043] see Figure 2-3 , the cleaning main ring 2...

Embodiment 2

[0048] see Figure 7-10 , the middle part of the outer gear ring body 21 is dug with a first negative pressure groove 211, and the inner bottom of the first negative pressure groove 211 is dug with a plurality of annularly distributed cleaning holes 212, and the middle part of the lower end of the power box 4 is equipped with a cleaning hole. 212 corresponds to the cleaning suction pipe 412, and the cleaning suction pipe 412 is connected with the dust suction auxiliary pipe 6. The middle part of the gear 41 has a second negative pressure groove 411 that is not easy to affect the cleaning suction pipe 412 dust suction. When the suction pipe 412 corresponds to the cleaning hole 212, a negative pressure is generated, which can effectively suck out the dust between the outer gear ring body 21 and the bellows body 1, and at the same time cooperate with the suction of the dust brushed out by the long-haired brush 23, and the double cleaning effect inside and outside, so that The cle...

Abstract

The invention discloses a corrugated pipe facilitating cleaning of gaps between corrugations, and belongs to the field of corrugated pipes. The corrugated pipe facilitating cleaning of the gaps between the corrugations comprises a corrugated pipe body. A cleaning main ring is in cup joint to the outer end of the corrugated pipe body. The upper end and the lower end of the cleaning main ring are inmeshing connection with power boxes. Cleaning auxiliary rings are arranged on the outer side of the cleaning main ring. Movable holes are chiseled in the two ends of each cleaning auxiliary ring. A distance adjusting device is connected between each power box and the corresponding movable holes. A plurality of dust suction auxiliary pipes are fixedly connected to the inner ends of the cleaning auxiliary rings. The ends, away from the dust suction auxiliary pipes, of the cleaning auxiliary rings are provided with dust suction main pipes. The interiors of the dust suction auxiliary pipes, the interiors of the cleaning auxiliary rings and the interiors of the dust suction main pipes are sequentially in communication, and dust in the corrugation gaps of the corrugated pipe can be convenientlycleaned. A cleaning device and the corrugated pipe are detachably connected, meanwhile, dust raising after cleaning is collected, cleanliness of the corrugated pipe is effectively guaranteed, dust isnot likely to influence the corrugated pipe telescopic degree, and the corrugated pipe is integrally more attractive.

Description

technical field [0001] The invention relates to the field of corrugated pipes, in particular to a corrugated pipe which is convenient for cleaning gaps between ribs. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and telescopic direction. Its open end is fixed, and the sealed end is in a free state. The auxiliary coil spring or reed is used to increase the elasticity. Under the action of the pipe, it is elongated along the length direction of the pipe, so that the movable end produces a displacement that has a certain relationship with the pressure. The bellows mainly include metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm diaphragm boxes and metal hoses, etc., metal bellows Bellows are mainly used to compensate pipeline thermal deformation, shock absorption, and absorb pipeline settlement deformation. They are widely used in petrochemical, ins...
