An electric coil type suction unit

Abstract

The invention discloses a novel electric coiled suction unit. The novel electric coiled suction unit comprises a unit box body, a coiled tube, a guide rod set, and a steel wire hose, wherein the unit box body is provided with a first side plate and a second side plate, and the first side plate and the second side plate are relatively arranged; a spiral groove is formed in the outer surface of the coiled tube, and spirally coiled to extend to the other end from one end of the coiled tube, and the coiled tube is erected between the first side plate and the second side plate through a rotating shaft; the guide rod set comprises a first guide rod and a second guide rod, wherein guide shafts are sleeved both on the first guide rod and the second guide rod, and both ends of each of the first guide rod and the second guide rod are correspondingly connected to the first side plate and the second side plate respectively; the steel wire hose is coiled in the spiral groove. In the novel electric coiled suction unit provided by the invention, the coiled tube with the spiral groove and the corresponding guide shafts are designed, so that the steel wire hose can be orderly coiled when wound and unwound to avoid failures of order confusion, mutual extrusion and the like easily occurring in the operation of winding and unwinding the hose.

Description

technical field [0001] The invention relates to a suction device, in particular to an electric coil type suction unit. Background technique [0002] In the past, the trains used the straight row method, and the excrement was directly discharged on the roadbed. The excrement was exposed to the sun and rain and turned into powder, which was blown by the hurricane caused by the passing of the train and turned into aerosol and flew into the air, forming air pollutants and even Germs spread. [0003] For this reason, more and more passenger trains have installed airtight toilets, which have further improved the advancement and comfort of passenger trains, and the vacuum unloading systems that are matched with it have also been more and more used. [0004] In the conventionally designed vacuum unloading system, due to the lack of directional guidance for the hoses, failures such as disordered sequence and mutual extrusion are prone to occur during the tube collection and discharg...

AI Technical Summary

Problems solved by technology

[0004] In the conventionally designed vacuum unloading system, due to the lack of directional guidance for the hoses, faults such as disordered order and mutual extrusion are prone to occur during the tube collection and discharge operations, requiring manual guidance, which seriously affects the operation phase rate and wastes human resources.
