Description

Technical Field

[0001] The invention belongs to the technical field of water tower cleaning equipment, in particular to an automatic water tower cleaner, in particular to a central rotating wall-attached self-priming and sewage-discharging automatic water tower cleaner. Background Art

[0002] Water towers are usually installed high up on the roof, and some are even installed on the slope of the roof. Moreover, the water tower itself is relatively high and the surface of the water tower is smooth, so it is easy for people to slip and step on air when they go up to the water tower, so cleaning the water tower is extremely dangerous. Every year, many people fall from heights and get injured or even die because of cleaning water towers. After opening the top cover of the water tower, because the water tank is relatively deep, it is out of reach by hand, so tools like mops are needed, but there are many dead corners that cannot be cleaned; another problem is that the deeper the water tank, the longer the handle required, the greater the torque, and it is very difficult to clean.

[0003] Generally, water towers are not cleaned intentionally. Most of the time, people check the water towers because there is sewage in the taps and find a lot of dirt accumulated at the bottom of the water tower. If this happens during a water shortage, it is a very embarrassing choice. If the water tower is completely emptied for cleaning, it means that not a drop of water will be used, and it is very wasteful.

[0004] The Chinese utility model patent No. 201020596875.X discloses an automatic water tower cleaning device, which includes a water tower automatic cleaning device, including a tower body, a water inlet pipe is provided at the upper part of the tower body, a water outlet pipe and a central tube with a water seal ring are provided at the bottom, the output shaft of the motor passes through the central tube and is connected to the cleaning brush, the central tube is connected to the sewage pipe with an electronic drainage valve, and the controller is connected to the motor and the electronic drainage valve through a wire. The present invention is mainly used for cleaning sludge at the bottom of rural water storage towers, mainly solving the difficulty of manually cleaning the sludge at the bottom of the tower, but the cost of the motor in the device is relatively expensive, and it needs electricity, which makes it impossible to use when the power is off. In addition, there will be a problem that after the cleaning brush is brushed, the liquid drives the impurities to move, resulting in the impurities being difficult to be discharged from the sewage pipe on the side.
