Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a non-contact transmission vector propulsion carrier of a thermohaline depth sensor, which aims to solve the problems in the prior art, can carry the sensor to detect data in the sea, transmit the data to a sea surface receiving base station in a wireless transmission mode, and transmit the data to a mother ship by the base station. The carrier adopts non-contact transmission so as to bear huge water pressure in a deep water area, and simultaneously has the function of controlling the deflection of the propeller in a non-contact manner so as to realize steering in the water.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in figures 1-2, the invention provides a non-contact transmission vector propulsion carrier of a temperature and salt depth sensor, which comprises a shell part, a power part and a vector control part. The housing comprises a front end housing 1 and a rear end housing 14. The front end shell 1 protects the motor and control circuit part of the power shaft 2 to prevent high-pressure seawater from permeating into the front end shell, and the rear end shell 14 wraps a copper disc 13 and 8 neodymium magnet blocks 12 uniformly distributed around the copper disc.
The neodymium magnet disc 7 is driven to rotate by the rotation of the power shaft 2, the magnetic field of the neodymium magnet disc 7 passes through a magnetic fluid bulkhead 10 (the magnetic fluid is ferroferric oxide colloid mixture), according to the lenz law, the neodymium magnet disc 7 interacts with a copper disc 13 of a propeller shaft 15 connected with a propeller 16, and the copper disc 13 spontaneously rotates along with the neodymium magnet disc 7 due to the characteristic that the magnetic flux is hindered from changing. Because of the large interaction of the neodymium magnet disk 7 with the magnetic fluid in the magnetic fluid compartment 10, a thrust bearing 4 is required to be installed to withstand the axial forces. The fixed end of the thrust bearing 4 is contacted with a magnetic isolating iron plate 3, and the magnetic isolating iron plate 3 protects a control circuit behind the power shaft 2 from the influence of a strong magnetic field of the neodymium magnet disc 7 to a certain extent.
8 coils 6 are evenly arranged around the neodymium magnet disk 7, and an iron core 5 is arranged in each coil 6, so that the magnetic field intensity generated after the coils 6 are electrified is increased. 8 small magnetic fluid compartments are uniformly arranged in the axial tail direction of each coil 6, and a spring 9 is arranged in each small magnetic fluid compartment. The periphery of the copper disk 13 is also uniformly provided with 8 neodymium magnet blocks 12, the positions of the neodymium magnet blocks correspond to the springs 9 and the coils 6 one by one, and the polarities of the neodymium magnet blocks are axially distributed. When the forward current is applied to the coil 6 x, the magnetic field generated in the same direction of the neodymium magnet block 12 x is attracted to each other at the two ends to overcome the force of the spring 9, so that the rear end is close to the point and is inclined, and when the reverse current is applied to the coil 6 x, the magnetic field generated in the opposite direction of the neodymium magnet block 12 x is generated, so that the rear end is far away from the point and is inclined. The whole rear end can be deflected on a ball hinge 11, and the deflection direction depends on the combined power-on and power-off, forward and reverse power-on and the magnitude of the electrified current of the coil 6. When all the coils 6 are powered off, the rear end can restore the original flat state under the action of the spring 9.
The large magnetic fluid compartment and the small magnetic fluid compartments distributed on the periphery are not communicated with each other, and a thin foldable iron sheet 8 is arranged in the middle of the large magnetic fluid compartment and used for reducing the influence of the neodymium magnet disc 7. The small magnetic fluid compartment is also provided with a foldable thin iron sheet 8 at the periphery for isolating the external seawater environment.
The non-contact transmission vector propulsion carrier of the temperature, salt and depth sensor is designed into a shell part, a power part and a vector control part. The neodymium magnet disc 7 is driven by the power shaft 2 to rotate, and the changed magnetic field enters the compartment filled with the magnetic fluid and is conducted to the copper disc 13 connected to the output shaft of the propeller to drive the output shaft to rotate. 8 coils 6 are evenly arranged around the neodymium magnet disk 7, and the power output end (copper disk 13) can be deflected in different directions and inclined at different angles in the same deflection direction by overcoming the acting force of the spring 9 through the interaction of a magnetic field generated by controlling the power on and off of the coils 6, the magnitude of current and the flowing direction and the neodymium magnet through the compartment filled with the magnetic fluid.
The principle and the implementation mode of the invention are explained by applying a specific example, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
