Description
Technical Field
The utility model belongs to the technical field of boats and ships electric field, magnetic field measurement, concretely relates to formula of sinking boats and ships electric field, magnetic field measurement device.
Background
When a ship sails in seawater, abnormal signals of a surrounding electric field and a surrounding magnetic field are caused. On one hand, the electric field and the magnetic field are exposed sources of underwater targets such as ships and the like, and are information sources for non-triggering fuzes of underwater weapons such as mines and the like to strike ships and submarine detection by a submarine monitoring network. In order to measure and evaluate the electric field and magnetic field level of the ship, the characteristics of the electric field and the magnetic field are analyzed. On the other hand, in order to break through the bottleneck problem limiting the development of the ship detection technology, it is necessary to acquire a large number of ship physical field signals to provide important data support for detection, identification and positioning of underwater targets such as ships. Both require the measurement of the electric field and the magnetic field of the ship and the marine environment.
For example, chinese patent application publication No. CN109579916A discloses a buoy-type integrated acoustic-electromagnetic detection device, which includes a housing structure, an acoustic-electromagnetic measurement unit, a data acquisition unit, a power supply unit, and a state monitoring unit. The upper part of the spherical watertight instrument cabin is made of transparent glass fiber reinforced plastic, the first layer below the spherical watertight instrument cabin is a solar panel, the lower part of the instrument cabin is made of nonmagnetic material and is positioned under water, and the MPPT controller is arranged below the solar panel. The interior of the device is composed of an acoustic electromagnetic measuring unit, a data acquisition and communication unit, a power supply unit and a state monitoring unit. The measuring unit comprises a hydrophone, an electrode sensor and a three-component fluxgate sensor; the data acquisition and communication unit consists of a data acquisition and data preprocessing module and a communication module; the power supply unit consists of a lithium battery and a power supply management module; the state monitoring unit is composed of a pressure sensor, an attitude sensor and a temperature sensor. The main disadvantages of this device are: (1) the buoy type measuring device is greatly interfered by electric fields of sea waves and other environments during sea surface measurement, and the measurement of three components of an electric field and a magnetic field is not facilitated due to the shaking of the measuring device; (2) because the platform is shaken, the magnetic sensor can only adopt a fluxgate sensor with relatively low sensitivity, and can not adopt an induction coil bar magnetic sensor with relatively high sensitivity; (3) the buoy type measuring device follows the wave on the sea surface and flows gradually, and the measuring position of the buoy type measuring device cannot be controlled.
For another example, chinese patent application publication No. CN109579916A discloses a method and system for seafloor geological surveying using vertical electric field measurements, in which for vertical electric field detection, a vertical arm base of a cylindrical tube, a preferred embodiment, is attached to a frame in a vertical direction relative to the seafloor. The vertical arm is inserted into the base and fixed by suitable fastening means so that it projects vertically above the frame and the electrical components of the unit. The vertical arm is in the form of a tube or rod of material having sufficient rigidity. To achieve the desired stiffness, polycarbonate (for example) or a similar durable plastic is preferably used to form the arms. Other materials such as PVC (polyvinyl chloride), polypropylene or the like may also be used if a material is used that reinforces or fills to provide rigidity. First and second vertically arranged (vertically displaced) electrodes are disposed at different points along the length of the vertical arms to form a vertically oriented dipole antenna. The electrodes preferably comprise silver-silver chloride electrodes, i.e. the same electrodes as used for the horizontal field measurement, which are connected to the data contained in the electronic housing by insulated wires and cables, respectively. The main disadvantages of the technical scheme are as follows: (1) the measuring device has an excessively complex structure and high processing and production cost; (2) the large-size and large-mass laying and recycling are difficult, the requirements on laying and recycling equipment are high, and an auxiliary ship with a suspension arm and a wide deck is needed to complete laying and recycling.
