The utility model discloses a wind driven generator blade replacing mechanism which comprises a blade shaft, rotating blocks are evenly installed outside the blade shaft, limiting grooves are formed in one sides of the rotating blocks, connecting blocks are installed inside the limiting grooves, extrusion protruding blocks are evenly installed on the two sides inside the limiting grooves, and the extrusion protruding blocks are connected with the connecting blocks. And fixing mechanisms are arranged on the two sides of the connecting blocks correspondingly, blade bodies are installed at the top ends of the connecting blocks correspondingly, and reinforcing strips are connected to the bottom ends of the two sides of each blade body and the two sides of the corresponding connecting block correspondingly. The sliding blocks are matched with the sliding grooves, the sliding blocks move under the rotating action of the blade body, so that the cleaning ring can clean the surface of the blade body, certain reverse thrust is provided for the sliding blocks under the action of the elastic strips, the springs, the top plate and the elastic cushion, reciprocating motion of the sliding blocks is promoted, and the cleaning effect of the blade body is improved. Therefore, the self-cleaning effect of the blade body is achieved.

This invention discloses an additive manufacturing-based inertial amplification nonlinear low-frequency vibration isolation metamaterial structure, vibration isolation device, and its performance control method. The vibration isolation metamaterial structure includes a rhombic frame structure, an inertial amplification unit, and a square spring structure. The square spring structure is arranged within the rhombic frame structure, with its two ends connected to a pair of opposite corners of the rhombic frame structure. The elastic extension direction of the square spring structure is parallel to the diagonal of this pair of opposite corners of the rhombic frame structure. The inertial amplification unit has a centrally symmetrical structure, including a rigid rod, two counterweights, and two diagonal rods. The center of symmetry of the inertial amplification unit, the center of the rhombic frame structure, and the center of the square spring structure all coincide in projection. Therefore, the vibration isolation metamaterial structure of this invention significantly widens the bandgap range and enhances low-frequency vibration isolation performance, exhibiting excellent performance in suppressing longitudinal waves in the 0-1000Hz low-frequency range, increasing vibration damping, and energy absorption.

The utility model relates to the technical field of hardware tools, and discloses a wrench with a torque detection function, which comprises a wrench head part, the wrench head part is butted with a wrench handle part through a torque detection component, one side of the wrench head part is fixedly connected with a hammer component, and one end of the wrench handle part far away from the torque detection component is provided with a hidden nail puller. An auxiliary handle assembly is arranged at the top of the wrench handle part; the torque detection assembly comprises a static torque sensor, a first U-shaped frame and a second U-shaped frame, the top of the static torque sensor and the top of the inner wall of the first U-shaped frame are fixedly installed, and the bottom of the static torque sensor and the bottom of the inner wall of the second U-shaped frame are fixedly installed. According to the wrench, the torque detection assembly is arranged, so that when the wrench is used for fastening screwing pieces such as bolts and nuts, the torque of the screwing pieces can be obtained when the screwing pieces are screwed, the situation that the screwing pieces are too tight or too loose can be avoided, the tightness of each screwing piece can be standardized without depending on the experience of operators, and the wrench is more practical.
