The invention discloses a plastic motor case and bearing device installing method, where the bearing device comprises gland, oil containing bearing and oiled felt, and the method comprises the steps of: 1) firstly injection-moulding a plastic motor case with bearing cavity for reserving; and II) placing the oil-containing bearing and oiled felt in the bearing cavity, and then fixing the gland on the bearing room to fix them in the bearing cavity. And it has advantages of simple process, low manufacturing cost, coaxial matching, low operating heat and long service life.

The invention discloses a large-scale ecological purse seine breeding device in shallow sea. The large-scale ecological purse seine breeding device in the shallow sea comprises a buoyancy system, a netting system, a dragon-shaped sandbag and an anchoring system, wherein the buoyancy system comprises double-row main floating pipes which are arranged in a parallel mode at intervals and a shore connecting structure which is fixedly arranged on the shore; two ends of the main floating pipes are respectively connected to the shore connecting structure and can longitudinally move up and down relative to the shore connecting structure; the netting system comprises a purse seine and the upper end of the purse seine is fixedly connected with the main floating pipes; the dragon-shaped sandbag is arranged at the bottom of the netting system; the anchoring system comprises a main anchor rope, the upper end of the main anchor rope is connected to the main floating pipes, and the lower end of the main anchor rope is fixedly arranged at the bottom of the sea through a piled anchor or an anchor block. The large-scale ecological purse seine breeding device in the shallow sea has the advantages of meeting the strength requirement of the buoyancy system of the purse seine by utilizing a mode of fixing the purse seine under the HDPE (high-density polyethylene) main floating pipes; ensuring a purse seine system to be always connected closely with a coastal connecting section and avoiding escape of the fish due to the fact that a buoy which is arranged in the shore connecting structure changes along with water levels; and being capable of avoiding the purse seine winding under different tide levels by arranging a chain and a floating ball string in the purse seine.

The invention discloses a gob-side entry three-dimensional reinforcement filled wall structure. The gob-side entry three-dimensional reinforcement filled wall structure comprises a wall body (9), a plurality of roof reinforcing anchor bolts (11) which are embedded inside the wall body (9) and the roof of a roadway, a plurality of floor reinforcing anchor bolts (12) which are embedded inside the wall body (9) and the floor of the roadway, a plurality of directional deformed steel bars (10) which are partially embedded inside the wall body (9), a plurality of dip wall penetration bolts (8) which penetrate the wall body (9), and a plurality of channel steels (13) which are provided with holes for the dip wall penetration bolts (8) to penetrate. Locking mechanisms fix the plurality of channel steels (13) onto the front side surface and the back side surface of the wall body (9). The gob-side entry three-dimensional reinforcement filled wall structure is simple in structure and low in filling cost and can meet the roadway side support requirements.
