Description

Technical Field

[0001] The utility model relates to the technical field of alarm, in particular to an underwater cable perimeter directional sound and light warning device based on magnetic levitation. Background Art

[0002] As an important source of clean energy, the safe operation of submarine cables in offshore wind farms is crucial. The underwater cable perimeter monitoring system is a key technical means to ensure the safety of underwater cables. The underwater cable perimeter monitoring system uses various sensors to monitor the physical quantities of the underwater cable perimeter in real time. When abnormal situations occur around the underwater cable, such as ships anchoring or illegal fishing, the sensors will capture the corresponding changes in physical signals. After these signals are transmitted to the monitoring center through the data transmission module, the data analysis software in the monitoring center will extract features and perform pattern recognition on them, judge the type, location, and severity of abnormal events, and issue an alarm in a timely manner;

[0003] For example, the "alarm system for detecting foreign ships inside and outside the underwater cable area" disclosed in the patent publication number CN114882735A can issue a warning to the corresponding ship by automatically triggering the function of the alarm module when the ship makes an action harmful to the underwater cable, so as to achieve the function of maintaining the safety of the underwater cable;

[0004] Existing alarm devices usually obtain external power through cables. However, due to the particularity of the marine environment, they are long-term exposed to harsh marine environments (such as strong winds, large waves, salt spray, etc.), and the cables are easily corroded and damaged by seawater and need to be replaced frequently.

[0005] At the same time, the alarm device rotates to turn, and mechanical friction and wear will occur during the turning process. Larger friction will increase power consumption. Content of the Utility Model

[0017] Preferably, an electromagnet tray is fixedly provided on the fixing seat, and the magnetic levitation electromagnet is embedded in a groove on the top of the electromagnet tray. The electromagnet tray loses magnetism when powered on, and cooperates with the suspended permanent magnet component by magnetic attraction when the power is off.

[0018] Preferably, a plurality of groups of bearings arranged circumferentially around the rotation axis of the horizontal rotating seat are vertically arranged on the top of the electromagnet tray near the inner side wall and the inner top wall of the horizontal rotating seat.

[0019] Preferably, a polytetrafluoroethylene isolation layer is provided between the transmitting board and the receiving board of the wireless power supply module.

[0020] Preferably, the vertical steering drive assembly includes a drive motor and a transmission shaft, the output end of the drive motor is connected to the transmission shaft through a gear transmission structure, and the sound player and the light-emitting assembly are respectively installed at both ends of the transmission shaft.

[0021] Preferably, the gear transmission structure comprises a first bevel gear and a second bevel gear meshing with each other, the first bevel gear is mounted on the output end of the driving motor, and the second bevel gear is coaxially mounted on the outer wall of the transmission shaft.

[0022] Preferably, the sound player uses a bass long-distance bagpipe; the lighting component uses a strong light irradiation lamp; the sound outlet direction of the bass long-distance bagpipe is the same as the light irradiation direction of the strong light irradiation lamp.

[0023] The utility model has the following beneficial technical effects:

[0024] The utility model is applied to the submarine cable perimeter monitoring system of an offshore wind farm. By means of directional sound and light warning, it can detect and alarm possible abnormal situations (such as submarine cable damage, illegal entry of ships into the monitoring area, etc.) in real time.

[0026] The electromagnetic clutch, the electromagnetic iron tray and the suspended permanent magnet form a double locking mechanism, and the double locking mechanism ensures the stability of the equipment in bad weather.

[0027] By adjusting the currents and directions supplied to the coils of the three groups of electromagnetic stators with a 120° angle and interacting with the rotating permanent magnet to generate a driving force, unrestricted rotation in the horizontal direction is achieved. Based on the electromagnetic force balance calculation of three axes, stepless motion and high-precision positioning are realized. This control method is relatively novel in similar devices and has higher control precision and lower power consumption compared with traditional control methods; at the same time, the rotation angle can be real-time feedback through a gyroscope, and the current and direction of the electromagnetic iron are adjusted to ensure the positioning precision.

The specific structure of the wireless power supply module 8 is an existing technology and will not be described in detail; the wireless power supply module 8 is internally provided with a polytetrafluoroethylene isolation layer 82.

The drive motor 62 is a stepping motor installed on the top of the linkage chassis 61. The first bevel gear 63 is installed at the output end of the stepping motor. The second bevel gear 65 is coaxially fixed in the middle of the transmission shaft 64. The first bevel gear 63 and the second bevel gear 65 are meshed to form a gear transmission structure.

[0054] In this solution, the electronic device is filled with epoxy resin silicone soft glue and sealed with a housing. The epoxy resin silicone soft glue has good waterproof, moisture-proof, and corrosion-proof properties, and can tightly wrap the electronic device to form a reliable protective layer.

[0056] The power supply module is used to connect to an external power supply, and it has a transmitting board 84 built-in;

[0057] The wireless isolated power supply module includes an energy conversion module, a storage battery, a starting capacitor, a high-efficiency multi-voltage conversion switch power supply, a polytetrafluoroethylene isolation layer 82, and a receiving board 83, etc.; The energy conversion module is used to convert the wireless power transmission voltage into a stable voltage to supply power to the storage battery; The high-efficiency multi-voltage conversion switch power supply is used to provide a stable power supply; The polytetrafluoroethylene isolation layer 82 is used to separate the transmitting board 84 and the receiving board 83;

[0058] The main control module is used to control and manage the entire system, perform data acquisition, control signal output, and perform wireless communication with the external host communication module through the wireless communication module; The main control module includes a main control board 66, as well as a gyroscope, a Bluetooth communication module, and an infrared communication head 85 connected to the main control board 66, etc.

[0059] The horizontal rotation control module includes a multi-current output control module and an electromagnetic stator 101. The multi-current output control module provides multiple adjustable current sources to control the electromagnetic stator 101 and can adjust the current magnitude according to requirements;

[0060] The vertical rotation angle control module includes a variable single-current output control module and a driving motor 62. The variable single-current output control module is used to provide 1 adjustable current source to ensure the stable operation of the driving motor 62;

[0061] The magnetic levitation control module includes a variable single-current output control module and a levitation permanent magnet 52. The variable single-current output control module is used to provide 1 adjustable current source to drive the levitation permanent magnet 52;

[0062] The warning device control module includes a 2-way switch control module, which is used to control the switch signals of the sound player 1 and the light-emitting component 2.

[0063] Working principle:

[0064] Vertical rotation angle control:

[0065] The driving motor 62 drives the first bevel gear 63 to rotate. The first bevel gear 63 drives the transmission shaft 64 to rotate through the meshing second bevel gear 65. The rotation of the transmission shaft 64 synchronously drives the sound player 1 and the lighting component 2 to adjust the angle.

[0066] Horizontal rotation control:

[0067] By supplying different currents and directions to the coils of the three groups of electromagnetic stators 101 with a 120° included angle and cooperating with two groups of rotating permanent magnets 51 with opposite magnetic polarities to generate electromagnetic force, the horizontal rotation of the horizontal rotating base 5 relative to the fixed base 4 is realized; during this process, the attitude of the horizontal rotating base 5 is monitored in real time by the gyroscope for feedback. The main control board 66 adjusts the electromagnetic force output of each of the three groups of electromagnetic stators 101 in real time according to the feedback information, and realizes extremely high-precision rotation by generating different currents; the contactless motion design is realized through magnetic force drive.

[0068] To realize the magnetic levitation of the horizontal rotating base 5 relative to the fixed base 4, control the electromagnet tray 7 to be energized and demagnetized, the three groups of magnetic levitation electromagnets 9 to be energized to generate magnetism, and the electromagnetic clutch 11 to be energized and disengaged. The magnetic levitation electromagnets 9 and the levitation permanent magnets 52 repel each other magnetically to realize magnetic levitation. At this time, there is a gap of about 1 mm between the inner top wall of the horizontal rotating base 5 and the top wall of the bearing 71.

[0069] After the horizontal angle is adjusted or in the power-off state, the electromagnet tray 7 has a magnetic force that attracts the levitation permanent magnet 52. The magnetic levitation electromagnets 9 are demagnetized, and the electromagnetic clutch 11 is engaged to realize the fixed connection between the horizontal rotating base 5 and the linkage shaft 81. At this time, under the action of the magnetic force, the inner bottom wall of the horizontal rotating base 5 abuts against the top wall of the bearing 71 to receive vertical support;

[0070] At this time, the fixation of the horizontal rotating base 5 relative to the fixed base 4 has double locking; one is the magnetic attraction between the electromagnet tray 7 and the levitation permanent magnet 52, and the other is the engagement fixation of the electromagnetic clutch 11. The double locking is to avoid misoperation or sliding.

[0071] The annular array of bearings 71 can not only provide vertical support for the horizontal rotating base 5 when it does not rotate, but also provide lateral support to improve stability when the horizontal rotating base 5 is subjected to lateral external forces.

[0072] The above embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
