[0002] Sediments at the bottom of water bodies, such as sand and silt, are one of the important factors affecting water quality. These sediments not only contain a large amount of organic pollutants and heavy metals, but also cause damage to aquatic ecosystems and affect the self-purification capacity of water bodies.

[0003] Bridge-type sand suction machine is mainly used in the horizontal aeration sedimentation tank of sewage treatment plant to extract the sediment at the bottom of the sedimentation tank. The sand suction machine moves back and forth along the length of the sedimentation tank on the rails. The sand suction pump on the machine sucks the sand and water mixture at the bottom of the tank out and discharges it into the ditch, or lifts it to a certain height and enters the supporting equipment for separation. Traditional mechanical equipment often has problems such as low degree of automation, poor cleaning effect, and high maintenance cost. Therefore, the market is in urgent need of an efficient and automated water bottom cleaning equipment. Utility Model Content
