Description

Technical Field

[0001] This utility model relates to the technical field of cables, specifically to a cable winding and unwinding device for a sludge dewatering machine in a sewage treatment plant. Background Technology

[0002] The working environment of sludge dewatering machines in wastewater treatment plants is harsh, filled with sludge dust, high humidity, and corrosive substances. The handling and protection of their electrical cables has long been a challenge. Currently, the industry mostly uses manual cable handling or simple reel devices, lacking targeted protective structures. On the one hand, cables easily become contaminated with sludge and impurities during handling; long-term adhesion can erode the insulation layer, increasing the risk of leakage and short circuits. Furthermore, accumulated impurities affect cable heat dissipation, shortening its lifespan. On the other hand, manual handling is inefficient, easily leading to cable tangling and knotting. Uneven winding can also cause localized stress and wear. In addition, existing devices lack effective isolation structures, allowing external sludge and moisture to easily enter the cable storage area, further exacerbating cable damage. This not only increases equipment maintenance costs but may also cause dewatering machine shutdowns due to cable failures, affecting the normal operation and maintenance of wastewater treatment plants. Utility Model Content

[0003] The purpose of this utility model is to provide an electrical cable winding and unwinding device for a sludge dewatering machine in a sewage treatment plant, so as to solve the problems mentioned in the background art.

The cleaning cover 201 is a hollow structure, and a top cover connected by a snap fastener is provided on the top of the cleaning cover 201. A cleaning sponge with a ring structure is provided inside the cleaning cover 201. When the cable enters the device from the inlet pipe 2, it passes through the cleaning sponge, which wipes the surface of the cable clean. After a period of use, the top cover is opened and the cleaning sponge is replaced. The cleaning cover 201 can be set in multiple sections, and the cleaning sponge in different sections contains water or other required cleaning solutions.

A take-up column 4 is installed between the two baffles 3. The two ends of the take-up column 4 are respectively rotatably embedded into the two baffles 3. The connection can be made with bearings to reduce friction. A drive motor 5 is installed above the baffles 3. The output shaft of the drive motor 5 is connected to the take-up column 4. The drive motor 5 is used to drive the take-up column 4 to rotate. A cable fixing mechanism is provided on the take-up column 4. The fixing mechanism includes a fixing groove 6 opened in the side wall of the take-up column 4. The fixing groove 6 is used to fix the cable end.
