5results about How to "Avoid potential threats" patented technology

The application discloses a kind of mountainous area highway slope rockfall protection equipment, including supporting mechanism;The supporting mechanism includes protection plate, and further include at least one first linear degree of freedom;At least four The protection plate is hinged between each other and is folded mutually;The technology of the application can flexibly unfold and adjust the position, angle and form of protection plate according to actual situation by the design of supporting mechanism, abutting mechanism and carrying mechanism.This makes the protection device can adapt to different shapes of slope and various rockfall angle, improves the overall adaptability.M type of unfolding mode makes impact force more evenly distributed on each folding layer, thereby reducing the risk of damage caused by excessive local stress.This helps to prolong the service life of protection plate, reduces maintenance cost.M type of unfolding mode makes the side with acute angle face the side of mountainous area slope rockfall, this design can better intercept and block rockfall.

This invention relates to the field of data processing technology, specifically to a method and system for early warning of network security threats based on big data. The method includes: identifying co-working users of the current user based on key information words and key information word vectors of the current user and other users in past predetermined time periods, and the work execution times of the current user and other users in past predetermined time periods; determining the data flow model of the current user based on the traffic data packets of the current user and co-working users in each past predetermined time period; inputting the traffic data packets generated by the current user during the current time period into the data flow model to obtain the predicted fields of the current user's traffic data packets in the current time period; comparing the predicted fields with the network flow transmission protocol fields corresponding to the traffic data packets; and determining whether to issue a network security early warning based on the attribute comparison results. This invention improves the reliability of network security early warning.

The utility model relates to the technical field of wall breaking machines, and discloses an all-metal steel cover for a wall breaking machine, which comprises a machine cover mechanism, a feeding mechanism and a hand-operating mechanism, the top end of the machine cover mechanism is fixedly connected with the bottom end of the feeding mechanism, the side surface of the machine cover mechanism is fixedly connected with the side surface of the hand-operating mechanism, and the hand-operating mechanism is fixedly connected with the machine cover mechanism. The machine cover mechanism comprises an outer side cover, the inner side of the outer side cover is fixedly connected with a steam blocking wall, the top end of the steam blocking wall is fixedly connected with a backflow wall, the top end of the backflow wall is fixedly connected with the bottom end of the outer side cover, and the bottom end of the inner side of the outer side cover is fixedly connected with a flow accumulation wall. The bottom end of the outer side cover is fixedly connected with the top end of the downstream wall, water drops liquefied by steam flow back to the inner side of the wall breaking machine by arranging the steam blocking wall and the backflow wall, potential threats of the water drops to a motor and a circuit are avoided, and the service life of the machine is prolonged; by arranging the feeding opening, food materials can be added without stopping the machine, and it is guaranteed that the food materials can be fully fused in the stirring process.

The invention belongs to the technical field of underwater operation equipment, and particularly provides a deep-sea mining vehicle plume treatment system which comprises a plume suction pipeline and a plume treatment integrated body, and the plume treatment integrated body comprises a plume suction pump, an electrochemical flocculation assembly and a cyclone; the electrochemical flocculation assembly comprises a sealed box body, a cathode and an anode; a fluid inlet is formed in the bottom of the sealed box body, and a fluid outlet is formed in the top; the input end of the plume suction pump is communicated with the plume collection main pipeline, and the output end of the plume suction pump is communicated with the fluid inlet; the fluid outlet is communicated with the inlet end of the cyclone, the floc outlet end of the cyclone is connected with a floc backfilling pipeline, and the overflow outlet end of the cyclone is connected with an overflow discharge pipeline. According to the plume treatment system for the deep-sea mining vehicle, chemical flocculants do not need to be added, and ecological safety is guaranteed; when micron-sized (the particle size is smaller than or equal to 15 microns) plume fluid particles can be treated, the plume treatment efficiency is remarkably improved.
