The embodiment of the invention provides a semiconductor wafer Mask ultra-high-cleanliness mute intelligent storage warehouse, and relates to the technical field of semiconductor manufacturing auxiliary equipment, the semiconductor wafer Mask ultra-high-cleanliness mute intelligent storage warehouse comprises a stacking station main body, a storage box body and a sliding guide mechanism, a storage cavity used for containing the storage box body is formed in the stacking station main body, and a high-efficiency air filter is arranged at the top of the storage cavity; the inner sides of the rims are in interference fit with flanges on the two sides of the I-shaped sliding rail, the magnitude of interference gradually changes in the length direction of the sliding rail, the storage box is of a double-layer hollow structure, a miniature constant-temperature and constant-humidity unit is installed on the inner wall of the box, and an intelligent monitoring module is further arranged on the stacking station body. And the intelligent monitoring module comprises a dust sensor arranged in the storage box body and a central controller arranged on the stacking station main body. The sliding mechanism has the effects of sliding stability, ultrahigh cleanliness and low noise.

The invention provides a maintenance data storage method based on an encryption technology, and relates to the technical field of industrial equipment maintenance data security. The method comprises the following steps that: terminal equipment acquires maintenance data, constructs an original data packet, and calculates an initial trust score of each transmission node; encrypting the original data packet and generating a digital signature, and constructing a security data unit; the transmission node performs verification and encrypted transmission in sequence to form an encrypted data link; the server calculates a dynamic trust score after receiving the data, verifies data integrity and updates a node trust score; generating a unique full-link traceability label for the verified data, and storing the unique full-link traceability label to the block chain; if verification fails, triggering an alarm and generating a responsibility definition report; and the authorized user can query full-link data through the traceability label. According to the method, the full-link credible traceability and tamper-proof protection of the maintenance data from generation to storage are realized, and the problem that the tamper link cannot be positioned and the responsibility cannot be defined by a traditional afterward verification mechanism is effectively solved.

This utility model relates to the technical field of hopper lifting devices, and in particular to a hopper lifting device for a mixing plant, which improves the storage reliability during concrete transportation and avoids leakage. By increasing the load of the power unit to offset the weight of the hopper, it reduces operating energy consumption. It includes a base and a guide frame, with the guide frame installed at the top of the base. It also includes a traction device, a power unit, a support seat, a bracket, and a hopper. The support seat is slidably mounted on the guide frame via the traction device. The bracket is mounted on the outer wall of the support seat. The hopper is eccentrically rotated and mounted on the outer wall of the bracket. The power unit is provided on the support seat. The power unit is used to support and limit the movement of the hopper and to provide power for the rotation of the hopper.

The utility model provides an atomizer and an electronic atomization device. The atomizer comprises an additional oil tank and a main body assembly. The additional oil tank has an additional storage chamber for storing an aerosol-generating substrate. The main body assembly comprises a first shell and an atomization assembly. The atomization assembly is arranged in the first shell. A main storage cavity used for storing an aerosol generating substrate is formed in the first shell. The additional oil bin can move relative to the main body assembly so that the atomizer can be switched between the first state and the second state. In the first state, the main storage cavity and the additional storage cavity are at least partially communicated, and in the second state, the main storage cavity and the additional storage cavity are not communicated. According to the atomizer, the additional oil bin can move relative to the first shell, stable and reliable liquid discharging can be achieved, and the assembling difficulty of the main body assembly and the additional oil bin is reduced.
