The invention is suitable for the field of ecological restoration engineering, and provides a high and steep rock slope ecological restoration structure. The structure comprises multiple stages of gentle slope belts, each stage of gentle slope belt comprises a rock slope body and a gentle slope platform, a drainage ditch is formed in each gentle slope platform, and water stopping ditches are formed in the two sides of each rock slope body which is further provided with a plurality of plant growing strips; each stage of gentle slope belt is further provided with a supporting assembly and a reinforcing assembly used for reinforcing the rock slope body and the plant growing strips of the gentle slope belt; each stage of gentle slope belt is further provided with a growing substrate layer and seed mixtures sown on the growing substrate layer, each supporting assembly comprises an iron wire net and a plurality of supporting anchor rods, the plant growing strips are installed on the iron wire nets, and each reinforcing assembly comprises an active protecting net and a plurality of reinforcing anchor rods. The invention further discloses a high and steep rock slope ecological restoration method. Because the reinforcing assemblies and the supporting assemblies are arranged on the rock slope bodies, the rock slope bodies, the plant growing strips and the growing substrate layers are reinforced, and plant growing stability and plant growing safety are improved.

The invention provides a clamping spring loading device of a ball valve automatic assembling machine, belongs to the technical field of machinery, and aims to solve the problems that an existing ball valve is assembled manually, the assembling efficiency is low, and the labor cost is high and the like. According to the clamping spring loading device of the ball valve automatic assembling machine, the ball valve automatic assembling machine comprises an operating table which his fixedly connected with a mold seat, wherein the mold seat moves together with the operating table; and the clamping spring loading device is arranged at the side edge of the operating table, and comprises a rack, a vibration material disc and a driving mechanism, wherein the top of the rack is fixedly connected with a horizontal guide rail which is movably connected with a manipulator, a material outlet of the vibration material disc is provided with a slide block, the slide block is provided with a material receiving groove, the driving mechanism can drive the slide block to perform reciprocating motion between the material outlet of the vibration material disc and the manipulator, and the manipulator can convey a clamping spring in the material receiving groove into a valve body at the mold seat. The clamping spring loading device has the advantages of high automation degree, capability of improving the assembling efficiency of the ball valve and the like.

The invention discloses a hydraulic simulator platform free from a washout algorithm in the direction of rotation on a Z axis. A worm gear and an annular guide rail are fixed coaxially at the upper end of a stationary platform foundation sequentially; the lower ends of sliding blocks in six sets of moving components are slidably connected with the annular guide rail respectively; the upper end of the sliding block in each set of moving components is connected with a sliding block fixing plate; a hydraulic motor is mounted on a first fixing plate on one side of the sliding block fixing plate; an output shaft of the hydraulic motor is connected with a worm; the worm is meshed with the worm gear; pulleys, adhered to convex edges of internal and external surfaces of the annular guide rail, are mounted in four corners on the lower side of the sliding block fixing plate respectively; and control lines of a control box mounted in the stationary platform foundation are connected with six servo motors respectively. The simulator platform rotates on the Z axis infinitely to avoid the washout filter algorithm in the direction of rotation on the Z axis, thereby effectively improving the reality of simulation, effectively improving travels in X, Y and Z directions, particularly in the Z direction, and greatly increasing the working space of the simulator.

The invention discloses a worm gear pair-based simulator platform capable of infinitely rotating around a Z axis. A worm gear and a ring rail are coaxially fixed on the upper end of a static platform base in turn; the lower ends of sliding blocks in six sets of moving parts are connected with the ring rail in a sliding mode respectively; the upper end of the sliding block in each set of the moving parts is connected with a sliding block fixing plate; a servo motor is arranged on a first fixing plate on one side of the sliding block fixing plate through a speed reducer; an output shaft of the speed reducer is connected with a worm, and the worm is meshed with the worm gear; four corners on the lower side of the sliding block fixing plate are respectively provided with a pulley wheel which is jointed with convex edges of the inner and outer side surfaces of the ring rail; and a control wire arranged on a control box in the static platform base is connected with six servo motors respectively. The simulator platform infinitely rotates around the Z axis to avoid a leaching-out filtering algorithm in the rotation direction around the Z axis, so that the validity of simulation is effectively improved, the length of travel in X, Y, and Z direction in particular the Z direction is effectively improved, and the working space of the simulator is greatly increased.

The invention relates to a tank-tank type liquid distributor which belongs to a liquid distribution element of a filler for heat transfer and mass transfer. The tank-tank type liquid distributor mainly comprises a first-stage tank, second-stage tanks, liquid guide tanks and clamping plates, wherein each second-stage tank is of a rectangular tank constituted by side surfaces and a bottom surface, big holes and small holes are formed on the two side surfaces, the big holes are positioned over the small holes, and a plurality of multiple groups of the big holes and the small holes are formed on the second-stage tanks; the second-stage tanks are arranged side by side for forming the shape of a circle and spaced and fixed by the clamping plates; the first-stage tank is of the rectangular tank constituted by the side surfaces and the bottom surface, and holes matched with the liquid guide tanks are formed on the bottom surface; upper bottom surfaces and lower bottom surfaces of the liquid guide tanks are sealed, the small holes are formed on the side surfaces of the liquid guide tanks, and the liquid guide tanks are embedded and fixed on the holes on the bottom surface of the first-stage tank; the first-stage tank is arranged on the circular surface constituted by the second-stage tanks in parallel and vertical along the length direction, the lower parts of the liquid guide tanks go deep into tanks of the second-stage tanks, and the liquid guide tank is arranged in each second-stage tank. The tank-tank type liquid distributor can effectively improve the uniformity of gas-liquid distribution, improve the mass transfer efficiency during the separation process and realize the enhancement of industrial integration process.
