Abstract: A rigid wind turbine blade mould structure capable of rapidly replacing a mould shell without change of supporting structure of the mould includes a stationary supporting structure for supporting an upper mould and a lower mould and a clamping structure for clamping the upper mould and the lower mould; wherein if the mould shell on the supporting mechanism is the lower mould, to change a different mould shell type, there is no need to move the bottom support adjusting devices to support the lower mould, and only lift away the lower mould profile/shell structure by an overhead crane; if the mould shell on the supporting mechanism is the upper mould, the upper mould needs to be turned over to be above the lower mould through the hinge beam, and the hinge beam supporting structure stays.

Abstract: The present disclosure provides an underwater helicopter with cycloidal rim vector propulsion. The underwater helicopter includes a disc-shaped underwater helicopter hull, a rim driving mechanism, paddles and rotation adjusting mechanisms. The rim driving mechanism is annular, and the diameter size of the rim driving mechanism is matched with the circumference size of the disc-shaped underwater helicopter hull. The rim driving mechanism is fixedly installed in a cavity in the circumference of the disc-shaped underwater helicopter hull. The rotation adjusting mechanisms are uniformly and fixedly installed on the outer side of the rim driving mechanism. The paddle is fixedly connected with the rotation adjusting mechanism.

Abstract: An apparatus and method for the automatic manufacturing of wind turbine blades, including an elongate tool support (2) with a main suspension beam (4), a plurality of support frames (8) supporting the main suspension beam (4) above the wind turbine blade mould (1), an elongate guide rail (5) provided on the main suspension beam (4) so as to extend longitudinally along the main suspension beam (4), a slider base (6) slidably mounted on the guide rail (5), a drive mechanism (53) for driving the slider base (6) longitudinally along the guide rail (5) and a tool holder (7) mounted on the slider base (6). The apparatus/method improves the efficiency and accuracy of the blade manufacture, and also reduces the exposure of the human body to harmful substances used in blade manufacture.

Abstract: An atomizer and an atomizing device are disclosed. The atomizer includes: an atomizing assembly for atomizing an atomizing liquid, and an atomizing cup including a cup body, a power supply interface and a cup mouth. The cup body is provided with a liquid storage portion having a liquid storage cavity for storing the atomizing liquid. The atomizing cup is further provided with an atomizing cavity in which the atomizing assembly is located. A flow channel portion with a flow channel is further arranged between the atomizing assembly and the liquid storage portion. The liquid storage portion is obliquely arranged away from the power supply interface, a corner is formed on a side portion of the flow channel away from the power supply interface, and a part of the liquid storage cavity is located on one side of the corner away from the power supply interface.

Abstract: A wind turbine blade mold structure includes reinforcing structures separately mounted on outer surfaces of a lower mold and an upper mold, and conformal support structures or support structures, each with one end fixed on the ground and the other end resisting the reinforcing structures; the conformal support structures or the support structures are adjustable in horizontal heights; the structure improves the flexural rigidity, thus greatly improving the anti-deformation capacity of a shell to simplify the support structures, accelerating the manufacturing and mounting process, reducing the dimensions of the structure, reducing the overall weight of a mechanism, facilitating the transportation, and reducing the energy consumption and pollution.
