SU93963A1 - Underwater Scraper - Google Patents

Description

The proposed scraper for underwater work with a propeller pasos in it, supplying water to erase in the soil collecting chamber of the shearing group and carrying the nulp to the trench curtain through the discharge branch pipe, prevents the soil particles from entering the pump, thus preventing it from abrasive impact. pulps.

FIG. 1 image scraper, side view; in fig. 2nd plot.

The underwater scraper has an operating slide 1, between which runners there is a self-rotating knife prism 2; Above it, it is welded to the grip slide of the dirt-collecting chamber 3 with a window in the bottom over the knife, the entire width of the skid; to the chamber, on the flanges, on the flanges of the water-supply pipe 4 with the outlet pipe 5; An ironeller pump 6 is pumped to the water-feeding pipe, sucking water in and then feeding it into the bulk-collecting chamber, above which is mounted an electric motor 8 in the metal casing 7, which drives a propeller pump that rotates and receives electric energy through the cable 9.

The shafts of the pump and the electric motor are located together with the other coupling 10. The casing of the electric motor is protected from the impact of the cable by the frame I. The scraper installation, together with the coastal winch, is powered by a mobile power station with an engine power of 80 liters. with.

Subject invention

A scraper for underwater works with a napelle pump that feeds water for washing away the soil that has been fed into the grain-collecting chamber and removed the pulverized material through the outlet pipe to the trench curb, characterized in that. In order to eliminate the nopadan in the pump, the soil primer, the soil intake is installed between the pipe in which the pump is mounted and the outlet pipe discharging the slurry.
