The invention discloses an ultra-large type offshore floating type platform and a butt joint forming method thereof. The floating type platform comprises a plurality of floating body units and connectors between the adjacent floating body units. Each connector comprises a connecting rod and further comprises a ball head base and a clamping assembly which are connected to the two ends of the connecting rod correspondingly. The floating body units are in inserted connection through outward stretching bosses and corresponding inward stretching bosses, and elastic supporting bodies are cushioned in inner cavities of the outward stretching bosses. Each connecting rod comprises a rod body and further comprises a ball head and a hinge lug plate which are arranged at the two ends of the rod body.The connecting rods penetrate through the top faces of the inward stretching bosses and the outward stretching bosses and the elastic supporting bodies, and the clamping assemblies penetrate through the hinge lug plate ends of the rod bodies of the connecting rods in a sleeving manner. The ball head bases sleeve the ball heads. The clamping assemblies are fixed to the top faces of the inward stretching bosses. The ball head bases are fixed to the outer ends of the elastic supporting bodies, and flexible structures are formed by the connectors. A pre-tightening device is further included, comprises a supporting frame and further comprises a connecting rod mechanism and a drive device which are fixed to the supporting frame. The connecting rod mechanism is connected with the hinge lug platesat the end portions of the connecting rods, and an execution component of the drive device is hinged to the connecting rod mechanism.

The invention discloses production equipment for aerated candies containing vitamin C juice. The production equipment comprises a stirring assembly, a columnar shell, a middle rotating rod, a connecting rotating rod and a butt-joint clamping base; the middle rotating rod is movably installed in the middle of the inner side at the upper portion of the columnar shell, the stirring assembly is fixedto the two sides of the middle rotating rod, and is in butt-joint fixation with the middle rotating rod through first connecting rods and second connecting rods, the second connecting rods are fixedlyinstalled above the first connecting rods, the stirring assembly is composed of a rotary stirring plate, a second protection plate, a first protection plate, a middle turntable and a two-shaft chuck,and the second protection plate is fixedly installed at the lower portion of the first protection plate. The production equipment for the aerated candies containing vitamin C juice has a double mixing structure, and the production efficiency of the production equipment is improved; meanwhile, the production equipment has a combined fixation structure, maintenance operation on the equipment is facilitated, and the safety of the equipment is improved.

The invention relates to a semi-open type water bearing plug-flow aerator. A semi-open type water bearing is arranged at the lower part of a hollow driving shaft by a water bearing sleeve core in a sleeving manner and comprises a left body and a right body which have semi-open symmetrical structures; the left body comprises a left-side plane flange, two side longitudinal flanges, a middle tubularbody, a bearing working surface coating layer and fall preventing barb bodies; one end surface of the middle tubular body is connected with the left-side plane flange; an upper open side and a lower open side of a semicircular tubular structure are both connected with the two side longitudinal flanges; a plurality of fall preventing barb bodies which are integrally arranged in a line manner in thecircumferential direction and the longitudinal direction of a bore are welded to the surface of the bore of the middle tubular body; the bearing working surface coating layer uniformly covers the surface of an inner hole of the middle tubular body to serve as a bearing working surface; the fall preventing barb bodies are naturally submerged and embedded in the bearing working surface coating layer. The semi-open type water bearing plug-flow aerator adopts a semi-open type water bearing composite material structural form, is stable and reliable in transmission support and is convenient and quick in mounting and maintenance.
