Description

Technical Field

[0001] The present invention relates to the technical field of safe navigation of ships, and specifically provides a collision avoidance system for pure electric ships based on a millimeter-wave radar device. Background Art

[0002] An electric ship refers to a ship powered mainly by electricity, which uses a battery, fuel cell or hybrid power system to drive an electric motor to propel the ship; with the improvement of environmental protection requirements and the development of new energy technologies, electric ships are becoming an important development direction in the shipping industry; among them, pure electric ships rely entirely on battery packs to provide power and are suitable for short-distance voyages or fixed routes; it is crucial to apply a collision avoidance system on electric ships, especially in the modern shipping environment where the ship density increases and the navigation conditions are complex, and the collision avoidance system can significantly improve navigation safety and operation efficiency.

[0003] Existing collision avoidance systems for pure electric ships can basically meet the daily use requirements, but there are still some deficiencies: firstly, most existing collision avoidance systems rely on lithium batteries in the ship for power supply, and using them together with navigation will consume additional ship power, affecting the effective navigation distance of the ship; secondly, most collision systems are connected to the ship's line structure by welding and fixing methods. Limited by the welding fixation, the later maintenance and disassembly are cumbersome. At the same time, the stability of the welding points is poor, and loosening or falling off is likely to occur after long-term use, thus affecting the working stability of the system; thirdly, the processing terminals of the system are mostly installed in the cabin, but affected by the wet and cold air on the water, the terminals are likely to be damaged by water vapor after long-term use, thus affecting the service life of the system.

[0004] Therefore, it is necessary to design a collision avoidance system for pure electric ships based on a millimeter-wave radar device. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1) The conversion module is set to connect the photovoltaic panel and the built-in power supply for power conversion. The light energy absorbed by the photovoltaic panel can be converted into electrical energy and stored in the built-in power supply, and then the built-in power supply powers the millimeter-wave radar, eliminating the need to use ship power and avoiding affecting the effective navigation distance of the ship.

[0017] 2) During the process, the gear motor drives the outer gear to rotate. The meshing of the outer gear and the central gear can drive the rotating bracket to rotate. In cooperation with the symmetrically arranged adjusting cylinders and adjusting heads that push at the bottom of the turning plate, the orientation angle of the photovoltaic panel on the turning plate is adjusted to ensure the energy conversion efficiency of the photovoltaic panel.

[0018] 3) The conversion module is docked with the plug-in block in the power box through the elastic docking component. After the connector is installed, it can be inserted into the support ring. At the same time, the compression spring in the support ring provides elastic force to tightly press the electrical contact piece against the connector to achieve circuit connection. This replaces the traditional spot welding connection and fixation, facilitating later disassembly and maintenance. At the same time, it avoids loosening or falling off of the connection caused by ship shaking, ensuring the stability of the power connection.

[0019] 4) The flowing shell arranged on one side of the radar terminal supports the power motor and the impeller. The power motor drives the impeller to rotate, which can accelerate the air flow on one side of the radar terminal. Then, through negative pressure, the air always passes through the radar terminal and flows out from the air outlet, forming a stable unidirectional flow wind direction. Before the air flows into the radar terminal, the moisture in the air is adsorbed by the dehumidification filling rods on the top bracket and the side brackets, and then the dehumidification effect is achieved by accelerating the air flow, avoiding damage to the radar terminal caused by moisture and extending the service life of the system.

The power motor 74 drives the impeller 75 to rotate, which can accelerate the air flow on one side of the radar terminal 11. Then, through negative pressure, the air always passes through the radar terminal 11 and flows out from the air outlet 72, forming a stable unidirectional flow wind direction. Before the air flows into the radar terminal 11, the moisture in the air is adsorbed by the dehumidification filling rods 78 on the top bracket 76 and the side bracket 77, and then the dehumidification effect is achieved by accelerating the air flow, avoiding the radar terminal 11 from being damaged by moisture and extending the service life of the system.
