The utility model discloses an ecological enclosure for lakefront zone ecological restoration belongs to lakefront zone ecological protection facility technical field, including a plurality of groups head -to -tail connection's ecological enclosure unit, wherein each group ecological enclosure unit includes the symmetry of two land connection piles and two water surface connection piles and the land connection pile and water surface connection pile of same side are fixed with two traction ropes of upper and lower through buckle between, two land connection piles middle welding fixed have the enclosure board, two water surface connection piles between fixed have the non - permeable flexible protection zone of strip shape through waterproof screw. The ecological enclosure has additionally designed the auxiliary enclosure of land area, is exclusively used for the ecological restoration of lakefront zone, and simultaneously through the design different shape's press strip structure with the adaptation of lakefront zone alongshore low -lying area, and the flexible protection zone is pressed into to the inside of lakefront zone alongshore low -lying area, can reduce the gap size of ecological enclosure lower extreme in lakefront zone high -low junction area, guarantees the enclosure effect.

The application relates to the technical field of electroplating, and discloses an electroplating wastewater evaporation crystallization device. The application comprises an evaporation barrel and a cooling pipe, and the electroplating wastewater evaporation crystallization device comprises a steam pipe, a reflux pipe, an evaporation mechanism and a filtering mechanism; the steam pipe is arranged on the evaporation barrel, and the reflux pipe is arranged at the lower end of the evaporation barrel; the evaporation mechanism comprises an inner barrel, a spiral plate, a heating rod and a crushing shaft; the inner barrel is arranged in the evaporation barrel; the spiral plate is rotationally arranged in the inner barrel; the heating rod is arranged in the spiral plate; and the crushing shaft is fixedly connected with the heating rod. The electroplating wastewater evaporation crystallization device is provided with a water tank; an inner tank is arranged in the water tank; a plurality of sliding grooves are arranged on the inner wall of the inner tank in an array; a filtering frame is slidably arranged in the sliding grooves; and filtering materials with different materials are arranged in the filtering frame and used for filtering the liquid to remove impurities.

The utility model provides a gap self -adjusting viscous damper relates to viscous damper field, include: damper cylinder body mechanism, damper cylinder body mechanism includes cylinder, end cover and first installation head, the inside of cylinder is provided with piston mechanism, piston mechanism includes guide rod, piston body, annular groove, through -hole, sealing washer and adjusting groove, the inside of piston mechanism is provided with length adjusting assembly, length adjusting assembly includes adjusting rod, screw groove, second installation head, internal thread fixed block and fastening bolt. The utility model, piston body becomes fierce in the activity of cylinder, along with the increase of damping medium flow velocity, pressure also increases in turn, and then the damping medium in annular groove inside extrudes the inboard of sealing washer, makes the through -hole outward extension, reduces the gap size of sealing washer outer wall and cylinder inner wall, and then increases the damping effect, through pressure extrudes the inboard of sealing washer, and then adjusts the gap.
