The invention discloses a critical control method and device for the water injection amount of a special containing cavity for a ship, and relates to the technical field of ship intelligent control. The method comprises the following steps: constructing a cavity state model; constructing a multi-objective optimization function based on the cavity state model; monitoring real-time sensor data, and after water injection enters a critical control interval, solving the multi-objective optimization function by using an NSGA-III algorithm to obtain a Pareto non-dominated optimal solution set; performing multi-attribute decision analysis on the Pareto non-dominated optimal solution set by using a TOPSIS method, and selecting an optimal control decision; and the optimal control decision is converted into a valve control signal to drive an execution mechanism to act, real-time feedback data is monitored, and water injection quantity critical control is executed in a rolling mode till water injection of the special containing cavity of the ship is completed. The problems that in the prior art, water injection control is low in precision and efficiency and large in impact when the ship swings are solved.

The utility model relates to the technical field of geological survey water injection test, disclose a water injection test device for water conservancy and hydropower engineering geological survey, including the bottom plate, the upper left side fixedly connected with water tank of bottom plate, the upper fixedly connected with water pump of water tank, the output fixedly connected with water pipe of water pump, install the flowmeter on one side of water pipe, one end fixedly connected with water box of water pipe, the right side bottom fixedly connected with water injection pipe of water box, the outside installation of water injection pipe lower side pressure sensor, the outside installation of pressure sensor is counterweight ring, the front and back both sides of water box all are fixedly connected with T block, the front side installation of T block front side is driven assembly, driven assembly is used for driving water injection pipe to move down and carries out water injection to the hole that hits.

The invention provides a device and method suitable for large-scale spawning induction of a single shellfish. The device comprises a rack, a spawning induction table, a water injection mechanism, a turnover mechanism, a temperature control mechanism, an oxygenation mechanism and an electric control box. The spawning induction table comprises a placement plate and a plurality of spawning induction cups; the water injection mechanism comprises a water injection support, a water injection pipe and water supply equipment. The turnover mechanism is mounted on the rack, drives the placement plate to rotate and is used for enabling the spawning induction cups on the placement plate to be arranged in an inclined manner; the temperature control mechanism is mounted on the placement plate and used for controlling the temperature of the spawning induction cup; the oxygenation mechanism is mounted on the placement plate and is used for supplying air to the spawning induction cup for oxygenation; and the electric control box is mounted on the rack and is electrically connected with the water supply equipment, the turnover mechanism, the temperature control mechanism and the oxygenation mechanism. The device is high in automation degree, the labor force is greatly reduced, single shellfish large-scale spawning induction can be achieved, and the device is widely applied to the genetic breeding fields based on family breeding, hybrid seed production, polyploid breeding and the like.

The utility model discloses a food processing machine with a good damping effect, which relates to the field of life electric appliances and comprises a machine base internally provided with a motor and a smashing cup detachably arranged on the machine base, a smashing device in transmission connection with the motor is arranged in the smashing cup, and a water tank communicated with the smashing cup is further arranged on the machine base. The machine base comprises a machine shell, a mounting part is arranged on the inner wall of the machine shell, the water pump is further sleeved with a flexible part, and the water pump is fixed to the mounting part through the flexible part, so that vibration generated in the working process of the water pump is effectively absorbed, transmission of the vibration to the mounting part is effectively reduced, and then vibration of the whole machine shell is reduced; the resonance phenomenon in the working process is avoided, the stability of machine operation is improved, meanwhile, flexible isolation of the water pump and the machine shell is achieved through the flexible piece, and therefore the situation that the water pump directly collides with the installation part to generate collision noise when working is effectively avoided, noise reduction is achieved, and the noise reduction effect is improved.

This utility model discloses a camel milk powder mixing device, including a base and a support frame fixed on the base, and further including: a mixing chamber installed on the upper part of the support frame, with a feed inlet at the top and a discharge outlet at the bottom; a water inlet located on the upper part of the mixing chamber, connected to an external water source via a solenoid valve; a battery and a control module located on the outside of the support frame; and a heating belt surrounding the outer wall of the mixing chamber. When the milk powder mixture inside the mixing chamber needs to be heated, the control module controls the annular heating belt to heat the mixture inside the mixing chamber. When the temperature sensor detects that the mixture has been heated to a suitable temperature, the temperature sensor transmits the information to the control module, which then controls the heating belt to stop operating, thereby achieving intelligent temperature control. This avoids excessive temperature causing nutrient loss in the milk powder and promotes effective mixing.
