Description
Technical field
The present invention relates to a kind of underwater research vehicle pilot system, particularly a kind of thermocline layer analog system of underwater research vehicle test usefulness belongs to the boats and ships field of ocean engineering.
Background technology
Because the radiation of the sun and the direct influence of atmosphere, the upper strata sea temperature in the ocean is higher, and convection current is vigorous, and water temperature is also relatively more consistent, is called homogeneous layer.In a lot of sea areas, the following sea temperature of last homogeneous layer takes place sharply to descend the formation temperature spring layer.Epilimnion and near the ocean thermal gradients heat energy that comprises, can be used as the propelling propulsive effort of underwater research vehicle.At present, the existing test that utilizes the underwater research vehicle success of ocean thermal gradients heat energy driving.In order to study really and to test, often to arrive big midocean and carry out on the spot sea examination, increased the difficulty and the funds consumption of scientific research.For this reason, answer flowing and the temperature traverse situation of manual simulation's thermocline layer, so that in the laboratory, test easily, analyze and study.In present prior art, do not have the precedent of similar pilot system, for the scientific research work of system has brought numerous difficulties and resistance.
Summary of the invention
For defective and the blank that remedies prior art, the invention provides a kind of thermocline layer analog system of underwater research vehicle test usefulness.The temperature traverse situation of the epilimnion that this system not only can exist in the real simulation ocean under artificial control, and can continuously change the speed of current in the pilot system, make the test vehicle under the environment of different ocean currents, test and to study.Water circulation in the pilot system uses, and has saved great amount of water resources.The main body of pilot system is the tank of cuboid, and its front and back is made by clear glass, makes things convenient for for observation analysis brings intuitively.Pilot system has also comprised data acquisition unit, for advantage has been created in the collection and the analysis of test figures.
The present invention is achieved through the following technical solutions.The present invention includes: tank, water tank, control/display unit, hot water circulating pump, automatically controlled hot water pump, automatically controlled cold water pump, temperature indicator, A thermocouple, flow counter, frequency-variable controller, data acquisition unit, electric heater, the A shutoff valve, cooling tower, B shutoff valve, overflow pipe, B thermocouple, C shutoff valve.

The water that tank water outlet bottom three circulations lattice flow out at first enters cooling tower by pipeline, and fully heat radiation guarantees that temperature reaches normal temperature in cooling tower spray process, enters automatically controlled cold water pump through pipeline again.Under the control of frequency-variable controller, with the flow that requires, flow through tank through three circulation lattice flow velocity on request of tank water inlet bottom once more through the A shutoff valve, lead to the water outlet place.
Because the hot and cold water flow point does not flow the two-layer up and down of tank, has formed flowing and the temperature traverse environment of approximate thermocline layer.
In process of the test, control/display unit is constantly gathered the signal that sends from flow counter, A thermocouple, B thermocouple, the constantly action of control electric heater, frequency-variable controller, make the warm water in the tank meet the requirements of temperature, make warm water and cold water flow velocity on request flow through tank, when the underwater research vehicle sample places the water commissioning test, as long as the kinematic velocity of underwater research vehicle sample itself is equal to or approaches water velocity, because the result of relative motion, the underwater research vehicle sample will keep being close to static state of kinematic motion in water.Water velocity in the tank is minimum to be 100mm/min, and the underwater research vehicle sample also can keep normally carrying out of test by the minimum speed operation of 100mm/min.
Beneficial effect of the present invention: the present invention can be under artificial control, and the temperature traverse situation of real simulation thermocline layer can continuously change the speed of current in the pilot system, makes the test vehicle test and to study under the environment of different ocean currents.Water circulation in the pilot system uses, and has saved great amount of water resources.The front and back of the tank of pilot system is made by clear glass, makes things convenient for for observation analysis brings intuitively.Pilot system has also comprised data acquisition unit, for advantage has been created in the collection and the analysis of test figures.The present invention is favourable for the ocean thermal energy being that the test of the underwater research vehicle of drive energy has been created, make things convenient for condition, has great practical value in scientific research and defense Industry.
