The invention discloses a rotatable multi-layer energy absorption quay fender. The rotatable multi-layer energy absorption quay fender comprises a fender body, wherein the fender body is connected with an impingement plate; the impingement plate is connected with a pair of springs; the springs are fixedly connected with rotating arms respectively; the two rotating arms are respectively mounted at the two ends of a pivot; two upper connecting pillars are connected under the pivot; the upper connecting pillars are connected with lower connecting pillars through rubber springs; and the lower connecting pillars are connected with a quay through substrates. According to the rotatable multi-layer energy absorption quay fender, the purposes of multi-layer energy absorption and counterforce decrease are achieved under the situation that the quay fender does not occupy redundant space through the polyurethane fender body, the impingement plate, spring layers and the rubber springs between the connecting pillars, and the energy absorption ability and impact resistance are greatly improved; and in the structural form, the fender and the quay are connected through a rotating system, the fender surface has certain horizontal speed when a ship body is moored alongside, and the fender body can rotate by a certain angle in the speed direction of the ship body and in the direction perpendicular to the pivot direction, so that the friction between the fender and the ship body is reduced, the horizontal load is reduced, and the friction damage to the ship body is reduced.

The invention discloses a wind power generation device with rear-mounted blades. The wind power generation device comprises a stand column, a wind power generation main engine and the blades. The main engine is hinged to the top of the stand column. The blades are installed on the tail of the main engine in a rear-mounted mode. A hydraulic piston cylinder capable of moving telescopically is further hinged between the upper portion of the stand column and the rear portion of the main engine. A piston of the hydraulic piston cylinder moves telescopically to adjust changes of the pitching dip angle, on the stand column, of the main engine. At least three steel cables are uniformly distributed on the upper portion of the stand column and fixedly connected to the upper portion of the stand column. The other ends of the steel cables are fixedly connected with a ground pile in a cable-stayed mode. Due to the design, the steel cables of the stand column and the blades do not interfere with each other in the cable-stayed process of the cables, wind resistance influence is small, diameter space of the blades is enlarged, the swept area of wind power is increased, power is increased, the dip angle can be controlled, adjusted and rotated for harmonizing loads of wind power, and the wind power can be tracked automatically; due to high-gradient hilly area arrangement, the blades rotate in an inclined mode to make the front side face wind, and the wind power is fully utilized; with assistance of the cable-stayed steel cables, the structural cost can be reduced, the defect of the poor wind-proof capacity in tradition is overcome, and the wind power generation device is suitable for being arranged on coasts with strong wind.

The invention relates to a suspended-rising support system of a tower crane, belonging to the field of building machinery. The suspended-rising support system comprises three sets of support structures which have same structure and are arranged up and down. When the suspended-rising support system works, the adjacent two sets of support structures support a tower body; each support structure comprises a support frame, a main girder, two symmetrical inclined struts as well as a first strut, a second strut, a third strut and a fourth strut, wherein the two symmetrical inclined struts are arranged at the lower part of the main girder and support the main girder; the first strut, the second strut, the third strut and the fourth strut support the main girder in the horizontal direction; the main girder, the two inclined struts and one ends of the four horizontal struts are respectively connected with the wall body; the upper part of the main girder is connected with the support frame; an expression of a pivot position of the main girder and the inclined struts is as follow: c(f-c)=a(f-a)+2a(f-c), wherein a is a distance from the action point of the frame at the outer side of a pivot O to the pivot O, c is the midline length of the frame along the main frame direction, and f is the calculation length of the main girder. The suspended-rising support system disclosed by the invention reduces the rigidity of the cantilever end, improves the action force of two main branches of the tower body near one side of a building to the main girder, enables the gravity of the tower body actedto the main girder to move inwards and reduces the horizontal load of the support structures to the building.

The invention provides a wall-mounted draining anchor rod barricade structure and a construction method thereof. The barricade structure comprises a longitudinal beam embedded in the top of a bank slope, a barricade and an anchor rod. The barricade is arranged at a by-water side of the bank slope. The longitudinal beam is positioned at a fundamental inner side of a protected bridge pile foundation. A plurality of cross beams is connected between a barricade body and the longitudinal beam. The construction method for the barricade structure comprises steps of constructing the anchor rod, constructing a draining hole, constructing the barricade, constructing an anchor pile, constructing the longitudinal beam, constructing the cross beams and installing a cut-off valve and the like. The barricade structure is capable of effectively solving problems existing in a large-scale reservoir hydro-fluctuation belt bank side cleugh area bridge pile foundation protecting technology, and advanced intechnology, and well in economy.

An anti-wind and wave device for offshore piles comprises a rubber disc body, an inflatable supporting device inside the disc body, a circular thin-walled steel hoop, and screws. The rubber disc body includes a rubber upper plate and a rubber lower plate, and the lower surface of the rubber upper plate ring-shaped edge and the rubber lower plate ring-shaped edge upper surface are prefabricated as a whole; the rubber plate body air chamber inflation matching device includes Inflatable nozzle, octagonal screw cap, air guide tube, gas valve switch, air pressure gauge, inflatable air pump. The advantage of this patent is that: when the pile body undergoes a large displacement and deformation under the action of horizontal load, the lower surface of the plate body contacts with the silt soil to generate a vacuum negative pressure effect, which stabilizes the horizontal load resistance of high-pile marine buildings Compared with other methods, the construction operation is quick and the project cost is low.
