The invention relates to a system for monitoring and forecasting mine underground water regime and intelligently controlling drainage and belongs to the technical field of management of the mine underground water regime. The hardware devices of the system comprise an underground local accumulated water well accumulated water volume detection sensor group, a main accumulated water well accumulatedwater volume detection sensor, an RS-485 communication network module, a liquid level detection device, a master control room computer, an underground drainage pumping station and a pumping station master control box, wherein the RS-485 communication network module comprises an RS-485 communication control bus, a bus communication controller and a repeater. The system has the advantages of savingenergy, reducing emission, reducing underground drainage cost, improving the safety of underground drainage, increasing the communication distance of an underground sensor, greatly reducing water level detection cost and improving system reliability. By the system, the underground water regime can be comprehensively known and controlled conveniently by a ground master-control room, and the safetyof the underground water regime is improved.

The invention relates to a vehicle-mounted emergency disinfection and purification device for drinking water in disaster environment, belongs to the technical field of gas discharge application and drinking water security control, and is technically characterized in that: on the basis of a narrow-gap dielectric barrier electric filed discharge reactor, a wide-gap dielectric barrier discharge reactor is additionally arranged to establish an oxygen active particle non-equilibrium plasma generation system, a two-stage gas-liquid efficient miscibility mode of a miscible booster pump and a venturigas-liquid miscible device is adopted to strengthen a chain reaction process that oxygen active particles form hydroxyl radicals, a plugboard disinfection and sterilization tank is adopted to extend a drinking water flowing line so as to prolong the disinfection and sterilization time of the drinking water, and the device can be integrally arranged on a steel bottom platform of an automobile so as to be convenient for transportation. The invention has the beneficial effects that: in the disaster environment, the disinfection and sterilization of the drinking water are improved, and the safetyand emergency supply of the drinking water are increased.

The invention discloses an AIS (automatic identification system)-based water area security protection alarm method. The method includes the following steps that: a water area where facilities requiring security protection is divided into grids, a security protection management table is established according to the coordinates of the grids, the coordinates of the facilities and the characteristic parameters of facilities, and an early warning and alarm parameter setting table is established; when ship information transmitted from a ship-borne AIS system is received, various kinds of parameters are extracted from the information, and the coordinates of the facilities and the appearance characteristic parameters of the facilities in the security protection management table are retrieved by using ship position coordinates; and distances between a ship and the facilities are obtained by using different algorithms according to different facilities, and whether the distances between the ship and the facilities and the speed of the ship satisfy set early warning or alarm conditions are judged. With the AIS (automatic identification system)-based water area security protection alarm method of the invention adopted, water surface facilities and underwater facilities can be protected; and early warning or alarm conditions can be set flexibly by a user, so that early warning or alarm against dangerous ships can be carried out fast and accurately. The method has the advantages of wide application range and flexible use, can provide security protection for water area facilities and has a certain economic value.

The invention discloses a water supply device for a large-scale breeding farm, which includes a breeding room body, horizontal dividing plates are fixedly connected to both sides of the inner wall of the breeding room body, and vertical dividing plates are also connected between the horizontal dividing plates. The sub-board and the vertical sub-board divide the breeding room body into a plurality of breeding rooms, and the breeding rooms are arranged in rows, and passages are also arranged between the breeding rooms in each row, and a water supply tank is also arranged on one side of the breeding room body. The input end of the water supply tank is connected with a water inlet pipe, the top surface of the water supply tank is also connected with a water pump through screws, and the water outlet pipe is connected between the input end of the water pump and the water supply tank. A water outlet pipe is connected between the water pipe, the output end of the water pump and the water distribution pipe. The invention has the advantages of reasonable design, stable operation of the water supply system, high degree of automatic control, convenient control of the water injection amount, and automatic cleaning of the water tank, which ensures the safety of drinking water for livestock.

The invention provides a vehicle water dispenser control method. When a user makes a cup make contact with a first pressure sensor on a lifting mechanism, the lifting mechanism can be triggered to godown, the cup is adaptively lifted to the portion under a water outlet end of a faucet, the water outlet end is made to be inserted into the cup, the water volume of the cup is detected, and the wateryield is determined according to the water volume of the cup; in this way, in the driving process of a vehicle, the user only needs to put the cup on the lifting mechanism with one hand, and the userdoes not need to take the cup with one hand and operate the faucet with the other hand; in the water collecting process, the water outlet end of the faucet is completely inserted into the cup so thatthe cup cannot incline, and then the phenomenon that hot water splashes to scald the user can be avoided, and the safety of water use of the user in the vehicle is improved.

The invention discloses a method for carrying out grouting water control on ore by utilizing pressurized pre-oxidized tailing neutralized paste materials as grouting materials. The pressurized pre-oxidized tailing neutralized paste materials are selected as the grouting main materials, the grouting materials are formed by proportioning and mixing the pressurized pre-oxidized tailing neutralized paste materials, milltailings, cement and binding materials. The pressurized pre-oxidized tailing neutralized paste materials have a certain gelation function and cheap availability, through multiple times of tests and technological demonstration, after the pressurized pre-oxidized tailing neutralized paste materials are proportioned with the related cement and binding materials, the requirement offield grouting water control can be completely met, the cement quantity in the grouting material preparation process is reduced, the grouting water control cost is reduced, the grouting water controldifficulty is reduced, and safety of grouting water control is improved; and grouting water control mining is carried out by combining an underground mining method, and the problems that the underground sewer drainage cost is high and efficiency is low are changed.
