Description

Technical Field

[0001] The present invention relates to the technical field of unmanned boats, and in particular to a centralized control device based on unmanned boats. Background Art

[0002] As we all know, unmanned boats are currently used as intelligent water operation equipment in the fields of environmental monitoring, marine exploration, military reconnaissance, etc. However, the control systems of existing unmanned boats generally have the following technical defects:

[0003] The control box of traditional unmanned boats mostly adopts fixed installation methods such as direct bolt fixing or snap-on structure. The connection between the control box and the unmanned boat body relies on multiple bolts or complex snaps, which need to be loosened or aligned one by one when disassembling. The electrical components (such as controllers, sensors, and communication modules) inside the control box and the line interface of the unmanned boat body are mostly fixed welding or hard connection. When upgrading or replacing components, rewiring is required, which has high maintenance costs and is prone to introduce failure risks. The traditional unmanned boat cooling method uses fans, but fans need to consume electricity continuously, increasing the energy burden of the unmanned boat, especially when operating at high temperature or high load. Insufficient heat dissipation capacity may cause electrical components to overheat and fail. Moreover, in salt fog, high humidity or low temperature environments, fans are prone to salt accumulation or condensation, causing motor failure; and in windy and rainy weather, water vapor will also enter the control box, affecting the normal operation of electrical components and easily causing safety hazards. Therefore, it is necessary to propose solutions to this technical problem. Summary of the invention

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a centralized control device based on an unmanned boat, which has the following beneficial effects:

[0020] The centralized control device based on the unmanned boat can realize the rapid locking or disassembly of the control box and the unmanned boat body by rotating the threaded ring on the bearing seat of the outer wall of the control box, without screwing the bolts one by one. The positioning mechanism is aligned with the positioning column on the installation groove through multiple positioning holes, ensuring that the line connector and the line interface of the body are aligned at one time when the control box is assembled, avoiding poor line contact or repeated adjustment due to misalignment. When the threaded ring is tightened, its ring groove is aligned with the fastening hole, and the fastening column is pushed into the ring groove by the telescopic mechanism to realize physical locking of the threaded ring to prevent loosening caused by vibration or impact.

[0021] When the unmanned boat is traveling, water naturally flows through the cooling chambers with two curved ends, and the heat of the battery box and the cooling medium is efficiently transferred to the water through the multiple cooling fins on the outer wall of the cooling box. Compared with the traditional fan heat dissipation, it has the characteristics of significantly lower energy consumption. The water pump only needs to pump the cooling medium such as ethylene glycol aqueous solution from the cooling box into the cooling chamber, and then circulate it back through the return pipe to form a closed circulation system to avoid evaporation or contamination of the medium. The two sides of the battery box are directly against the cooling box to quickly transfer the heat of the battery to the cooling medium, avoiding overheating of the battery and extending its life.

[0022] The guide plates at both ends of the cooling chamber are in the shape of guide wings, which guide the water flow to enter and discharge quickly, reduce water resistance, and avoid water short circuit, ensuring that the medium in the cooling chamber is fully in contact with the heat dissipation fins, and improving the heat dissipation efficiency. The water pump is only started when the unmanned boat is driving, and is driven by motion kinetic energy, or automatically adjusts the speed according to the feedback of the temperature sensor to avoid idling power consumption. Compared with the traditional compressor refrigeration system, the energy consumption is reduced, the water cooling system does not require a fan, and salt spray and dust are prevented from entering the control box, reducing the risk of electrical component failure, improving equipment reliability, and low power consumption. Extend the endurance time of the unmanned boat and reduce the frequency of charging and battery replacement;

[0023] The present invention systematically solves the problems of complex installation, low heat dissipation efficiency, poor sealing and weak environmental adaptability of traditional unmanned boat control systems through a quick splicing mechanism, a water-cooled circulation system, a multi-stage sealing structure and a modular design. The kinetic energy of the unmanned boat is converted into heat dissipation power, and a hybrid mode of passive heat dissipation and active circulation is combined to achieve low-energy and high-efficiency heat dissipation. At the same time, through standardized interfaces and quick disassembly and assembly design, the maintenance efficiency and equipment reliability are significantly improved, providing reliable technical support for the long-term and intelligent operation of unmanned boats in complex waters.

The docking tube 19 is installed at the bottom end of the mounting column 5 and connected to the cooling chamber 9. The sealing hole is opened at the bottom end of the control box 2. The docking tube 19 and the transmission tube 13 are both against the sealing hole. When the mounting column 5 is against the sealing groove, the docking tube 19 at the bottom end of the mounting column 5 is inserted into the sealing hole. Then when the control box 2 is assembled on the mounting groove 4, the transmission tube 13 is aligned with the sealing hole and enters, so that the cooling medium enters the docking tube 19 through the sealing hole, and then enters the cooling chamber 9 through the docking tube 19, thereby realizing rapid docking of the tube 19, which is convenient for cooling and cooling operations.

[0042] The following is a table of comparative experimental data, which is used to intuitively demonstrate the performance difference between the traditional fan cooling system and the water cooling system of the present invention:

[0043] Comparative Experimental Data Table

[0044]

[0045]

[0046] The traditional system operates in a static state without water flow to assist heat dissipation, while this structure relies on the water flow when the unmanned boat is traveling for natural cooling, so it needs to be tested under dynamic conditions. The load of electrical components is the same 100W to ensure fairness of the comparison. The traditional fan system needs to continuously run a high-power fan of 40W, while this structure only needs a low-power water pump of 7W, reducing the total energy consumption by 82.5%. The reason for the low power of the water pump is that the natural circulation of water flow reduces the driving demand of the cooling medium. In a high temperature and high humidity environment, the fan heat dissipation efficiency of the traditional system is limited, and the component temperature is as high as 70°C; this structure controls the temperature at 50°C through a water cooling cycle, reducing the temperature by about 28.6%, significantly improving the life and stability of the components. The traditional system relies on fans to inhale air, which is easy to inhale salt spray or dust, and the sealing is only IP54; this structure adopts a fully sealed design IP67, a fanless structure, to avoid the intrusion of external pollutants, and has higher reliability. The fan needs to be cleaned or replaced regularly about once every 3 months, while this structure only requires annual cooling medium replacement, reducing maintenance costs by 75%.

[0047] This structure is significantly superior to traditional fan systems in terms of energy consumption, heat dissipation efficiency, sealing and maintenance cost, especially in complex water environments such as high salinity, high temperature or high humidity scenarios, and can effectively improve the long-term operation reliability of unmanned boats.
