Pneumatic type jet flow washing and sucking desilting system for hydropower station overhauling gate groove

Abstract

The invention discloses a pneumatic type jet flow washing and sucking desilting system for a hydropower station overhauling gate groove. A large frame, a small frame, a slide carriage and a jet flow washing and sucking desilting device are included; the large frame is used for conveying the jet flow washing and sucking desilting device onto the sand face of the water bottom as a carrier; the smallframe is installed on the large frame through a longitudinal horizontal movement device; the slide carriage is installed at the bottom of the small frame through a transverse horizontal movement device; the jet flow washing and sucking desilting device is fixedly installed on the slide carriage, and is used for performing washing and sucking desilting on the water bottom; and through the longitudinal horizontal movement device and the transverse horizontal movement device, the jet flow washing and sucking desilting device can be conveyed to the sand face of the water bottom from the shoreside, and moves within a large range on the sand face of the water bottom. According to the pneumatic type jet flow washing and sucking desilting system for the hydropower station overhauling gate groove,the sand washing and sucking area of the jet flow washing and sucking desilting device is enlarged due to the longitudinal horizontal movement device and the transverse horizontal movement device. The pneumatic type jet flow washing and sucking desilting system for the hydropower station overhauling gate groove is good in desilting effect, large in area, high in efficiency and capable of effectively solving the dust and sand silting-up problem of the hydropower station overhauling gate groove.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, relates to a silt removal equipment for a gate of a hydropower station, and in particular relates to a pneumatic jet flushing and suction dredging system used for a gate groove of a hydropower station for maintenance. Background technique [0002] The rivers in my country are sandy, and sediment deposition is often a key problem in the construction of water conservancy projects. The water flow intensity of the inlet sluice groove and its vicinity of the water conservancy project unit is weak, and sediment deposition is easy to occur. The silt deposition in the inlet gate slot of the water conservancy project unit and its vicinity will make the maintenance gate unable to land in place in time and accurately. In order to complete the maintenance of the unit, professional divers have to be invited to carry out underwater dredging, which not only increases the cost but also has potential ...
