The utility model provides a kind of solid raw material dewatering equipment for three-proofing glue production, belong to the technical field of glue production, including bearing mechanism, including adsorption tower, fixed installation in the top of adsorption tower pipe body and the sealing cover of movable installation in the top of pipe body;Mounting mechanism, including ring sleeve.The utility model is by box body and support disc to realize molecular sieve granule board whole quick replacement, greatly shorten downtime, avoid production interruption;Sealing cover and mechanical interlock's positioning assembly ensure that adsorption tower is airtight when disassembling, prevent air moisture absorption or dust leakage;Spring support and limiting structure of jacking assembly auxiliary one-key type release locking mechanism, reduce artificial intervention, avoid the risk of forcible disassembly when high temperature is not pressure relief;Prepackaged filling type molecular sieve granule board is directly replaced, and particle crushing and pipeline pollution are eliminated.These designs comprehensively improve replacement efficiency, safety and sealing, solve the production bottleneck and hidden danger of traditional replacement mode.

According to the large-scale circuit breaker rapid replacement device used in the low-voltage power distribution system, rolling translation devices used for supporting a circuit breaker in a rolling mode are installed on the two sides of the upper plane of a lifting trolley, and an angle adjusting device installed at the front end of the middle of the upper plane of the lifting trolley is located between the two rolling translation devices. When the height of the lifting trolley is adjusted to be flush with the circuit breaker, the pulled-out circuit breaker is located on the front half section of the rolling translation device, the inclination angle of the circuit breaker is adjusted through lifting and rotation of the angle adjusting device, and the circuit breaker is translated to the rolling translation device; and the circuit breaker of the lifting trolley is moved out of the low-voltage power distribution cabinet through a push rod at the rear end of the lifting trolley. According to the utility model, the problem that potential safety hazards exist in the process of pulling out and carrying the circuit breaker in a manual replacement mode is solved, the labor intensity of replacing the circuit breaker is reduced, the potential safety hazards caused by improper operation of personnel are eliminated, the working efficiency is improved, the power failure time for maintaining and repairing the circuit breaker is shortened, and the power supply reliability is improved.

The invention relates to a hidden accident association degree evaluation method based on an intermediate index, and the method comprises the following steps: building an accident database, collecting accident cases, and building an accident database; extracting sentence vectors of the hidden danger text, and extracting sentence vectors of hidden danger description by using a BERT model; constructing a hidden danger text tree, and constructing the hidden danger text tree and a hidden danger text-index sequence data set through k-means clustering; constructing and training a hidden danger index sequence generation model, and predicting a hidden danger index sequence by using a transform model framework; hidden danger similarity calculation: generating an index sequence and calculating hidden danger text similarity; and evaluating the degree of association of the hidden accidents, and evaluating the degree of association based on the similarity and the accident weight. The technical problems that in the prior art, hidden danger text semantic understanding is insufficient, and a hidden danger and accident association weight evaluation mechanism is inaccurate are solved.
