This invention relates to an integrated rescue system for drowning victims, comprising a protective device, a maritime rescue device, and a delivery system. The protective device includes a protective shell, a shell hoisting mechanism mounted on the shell, and a shell zipper mechanism. The maritime rescue device is housed within the protective shell and includes a foldable airbag mechanism, a foldable stretcher mechanism, a stretcher hoisting mechanism, and a positioning system. The delivery system includes a drone and a delivery device. The delivery device is mounted on the shell hoisting mechanism to hoist the protective device. After the drone locates the drowning victim, it delivers the protective device. The shell zipper mechanism unlocks under pulling action to release the maritime rescue device, inflating and deploying the airbag mechanism. The stretcher mechanism then unfolds, and the drowning victim lies on the unfolded stretcher mechanism. The positioning system reports the location to the rescue command center in real time. The stretcher hoisting mechanism, under the lifting action of the rescue helicopter, detaches the airbag mechanism and the stretcher mechanism, lifting only the stretcher mechanism that secures the drowning victim.

This application relates to the field of electricity market trading technology and provides a method for electricity spot market trading based on blockchain technology. The method includes: trader i sending an order for purchasing or selling electricity to a node; based on the PBFT consensus mechanism adopted by the electricity trading blockchain platform, the regulator selects an endorsement node and a sorting node for the order information; the endorsement node queries trader i's previous transaction record to determine the additional waiting time added to the order information in this transaction; based on the trading rules and the subjective risk preferences of trader i and trader j, a transaction order is formed, and a transaction contract is generated; the endorsement node verifies the transaction information based on the smart contract and settles the transaction amount; after verifying the transaction information, the sorting node adds a new block to the blockchain; the new block contains the transaction information. This method can address the risks of transaction default and spot price fluctuations.

The utility model discloses a pH value monitoring device for urban water supply, and relates to the technical field of water quality detection, the pH value monitoring device for urban water supply comprises a main pipeline fixedly connected with a water supply pipeline, and the two ends of the main pipeline are respectively clamped and matched with flow velocity retarders; the flow speed slowing device comprises an outer ring sleeve inserted into the inner side of the main pipeline, the two ends of the outer ring sleeve are fixedly connected with an outer baffle and an inner baffle respectively, and filtering through holes are formed in the inner baffle on one side of the main pipeline in a rectangular array mode; according to the utility model, the two ends of the main pipeline are respectively provided with the outer baffle plate and the inner baffle plate which are mutually staggered, the water flow speed in the main pipeline is reduced by utilizing the outer baffle plate and the inner baffle plate which are staggered, the transverse impact on the pH value sensor detection probe is reduced, and the service life of the pH value sensor detection probe is further prolonged; moreover, the waiting time of a water source can be prolonged between the two inner baffles, enough monitoring time is provided for a pH value sensor detection probe, and the detection quality is further improved.

The application discloses a kind of Australian freshwater lobster synchronous oviposition parent screening equipment and screening method thereof, it is related to aquaculture technical field, including;Optical machine, support block and support, the optical machine is arranged at the top of support, the support block is rotationally arranged on support, and the inside of the support block is equipped with cavity, the support block is equipped with the placing box of transparent material, the inside of placing box is equipped with storage cavity, the placing box is equipped with recess on one side and close to support, the side end of support is equipped with shielding component, the drive mechanism that can control the rotation of support block is equipped in support, the air inlet is equipped on the support block, and the air blowing equipment with cold and hot alternation function is arranged at the air inlet, by;Optical machine can obtain the shooting image of female red-clawed crayfish, and the time of female red-clawed crayfish reproduction molting is judged according to the shape and size of gastrolith, so as to select the parent of basically synchronous reproduction molting, reach the purpose of screening synchronous oviposition parent.

The application relates to the technical field of washing machine dehydration control, and provides a dehydration control method of a washing machine, which comprises the following steps: presetting k gears; determining a target rotating speed and a target eccentricity upper limit according to a target gear of dehydration; entering a target gear access control stage: under the condition that the actual front-end correction execution times are less than or equal to the front-end correction upper limit, cyclically executing front-end correction and updating the actual eccentricity; if the actual eccentricity is less than or equal to the target eccentricity upper limit, the washing machine is dehydrated at the target rotating speed; if the front-end correction actual execution times are greater than the front-end correction upper limit and the actual eccentricity is greater than the target eccentricity upper limit, a highest safety gear decision stage is entered: a highest safety gear is found, and the eccentricity upper limit of the next gear of the highest safety gear is less than the actual eccentricity and is less than or equal to the eccentricity upper limit of the highest safety gear. The application solves the technical problem of poor dehydration effect of a traditional washing machine.

The present application relates to the technical field of cleaning equipment control, and particularly relates to a time sequence control method for multi-layer filter screen partition cleaning, comprising the following steps: generating a basic cleaning time sequence composed of walking period, air jet period, water jet period and rest period according to the layer position sequence of each cleaning partition in the multi-layer filter screen and the walking direction of the moving cleaning platform; identifying the time sequence transfer position between adjacent cleaning partitions as an interference transfer point, and inserting a blocking time sequence at the interference transfer point to generate a partition composite cleaning time sequence; the blocking time sequence is used to make the next cleaning partition delay entering the water jet period and execute air jet isolation or rest dispersion first after the air jet or water jet of the current cleaning partition ends; and the multiple moving cleaning platforms are controlled to operate in partitions according to the partition composite cleaning time sequence. The present application avoids the problem of pollutant migration to adjacent partitions caused by the next cleaning partition immediately entering water jet operation after the air jet or water jet of the current cleaning partition ends.
