Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture and water environment management equipment, specifically a water aeration device based on an unmanned vessel platform with an assembled magnetic quick-release structure and a multi-directional adjustment mechanism. Background Technology

[0002] In aquaculture and river management, aeration equipment is a core component for maintaining dissolved oxygen levels in water. However, most widely used equipment is of a fixed design, significantly limiting its functionality. Traditional devices typically fix the blower and aeration pipe directly to the hull or floating platform via welding or rigid connection, resulting in a completely fixed position and angle for the aeration unit. This design makes it impossible to adjust the equipment according to needs.

[0003] Meanwhile, the low maintenance efficiency of traditional fixed connections is particularly prominent. The rigid connection structure between the equipment and the carrier requires complex disassembly when repairing or replacing the blower, which is time-consuming and relies on specialized tools; in humid environments, fixed components are prone to rust and adhesion, further increasing maintenance difficulty. Some improvement solutions attempt to adjust the aeration depth using robotic arms or rope systems, but these designs are bulky, and after long-term immersion, corrosion can cause moving parts to jam, increasing the failure rate and making it difficult to meet the long-term requirements of lightweight and low-cost aquaculture.

[0004] Existing modular designs still have shortcomings in practical applications. For example, quick-release structures rely on precision plug-in or snap-locking, which has low tolerance for error in turbid water or emergency situations, making it difficult to quickly complete disassembly and assembly. After long-term use, connecting parts are prone to failure due to material fatigue or wear, affecting equipment reliability. These problems result in low repair efficiency for traditional devices in the event of sudden failures, and prolonged downtime may lead to a sharp drop in dissolved oxygen in aquaculture water or river water. At the same time, fixed designs lack flexibility and cannot adjust aeration modes according to seasonal changes or aquaculture stages. For example, during the high temperatures of summer, bottom aeration needs to be enhanced to inhibit the growth of harmful bacteria, while energy consumption can be reduced in winter, but existing equipment struggles to achieve such dynamic adjustments, leading to energy waste or insufficient oxygenation.

[0005] Current technological solutions, due to their rigid structures, weak adjustment capabilities, and low maintenance efficiency, are no longer sufficient to meet the demands of modern aquaculture for precision and high efficiency. Traditional equipment exhibits significant limitations, especially when dealing with insufficient dissolved oxygen at the bottom, complex aquatic environments, or emergency maintenance scenarios. Therefore, there is an urgent need for an innovative design that allows for quick assembly and disassembly, flexible adjustment of aeration angles, and adaptation to high humidity environments to improve the uniformity of dissolved oxygen in the water, reduce maintenance costs, and ensure the stability of aquaculture production. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a magnetic aeration device that can be installed on an unmanned vessel.

[0007] The technical solution of this utility model is as follows: a magnetic aeration device mounted on an unmanned surface vessel (USV), comprising the USV, the hull of which is a steel structure and controlled by a hull control device, with symmetrical slide rails on both sides, each slide rail embedding an electromagnetic lock module; the blower module includes a PVC hose, with both ends of the hose connected to a porous air-filling pipe and a blower, the base of the blower being fixedly connected to a permanent magnet, the permanent magnet being detachably connected to the electromagnetic lock in the slide rail via magnetic attraction; the connection mechanism includes a universal adjustment module, which consists of a dual-axis rotation mechanism and a small servo mechanism, the small servo being magnetically connected to the electromagnetic lock, its output shaft being driven by the universal adjustment module via a gear set, the protruding structure of the electromagnetic lock matching the guide groove of the slide rail; the slide rail integrates a conductive strip and a data interface, the data interface being Type-C, used for powering the blower module and communicating with the controller, with limit blocks at both ends to prevent the blower from detaching.

[0008] Furthermore, the electromagnetic lock has a magnetic flux density ≥1.2T, the magnetic force disappears after power is cut off, and the distance between the permanent magnet and the electromagnetic lock's adsorption surface is ≤1mm.

[0009] Furthermore, the angle control accuracy of the universal adjustment module is ±1°, and the torque of the servo motor is 2.5 kg·cm.

[0010] Furthermore, the inner side of the slide rail is provided with a guide groove, which is 5mm deep and 22mm wide, and matches the protruding structure at the bottom of the electromagnetic lock to prevent longitudinal displacement.

[0011] Furthermore, the relay is connected to the hull control module via a GPIO interface and is mounted on the unmanned vessel to control the switching of the fan and electromagnetic lock.

[0012] Furthermore, one end of the PVC hose is connected to a porous air-filled pipe, with a waterproof sealing ring at the connection point, and the other end is connected to the external interface of the blower, extending to the water on both sides of the hull to transmit the high-pressure gas generated by the blower to the water.

[0013] The beneficial technical effects of this utility model are:

[0014] The equipment's overall performance is enhanced through a magnetic quick-release structure, a multi-directional adjustment module, and an integrated slide rail design. Compared to traditional bolt fixing methods, the magnetic quick-release module uses an electromagnetic lock and permanent magnet for attraction and locking, enabling rapid assembly and disassembly of the blower, significantly reducing maintenance time and effectively ensuring operational continuity and efficiency. The multi-directional adjustment module supports precise multi-angle control, allowing flexible adjustment of the aeration direction, solving the oxygenation blind spot problem caused by traditional fixed aeration methods, and improving the uniformity and efficiency of oxygen distribution. The integrated conductive strip design of the slide rail avoids the impact of cable entanglement and hull movement on equipment stability, enhancing operational reliability. Furthermore, the standardized interface design of the slide rail supports rapid adaptation to blowers of different power ratings, expanding the equipment's applicable scenarios and enabling it to efficiently handle the challenges of large-area water management and complex terrain, demonstrating high practicality.

[0021] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] See appendix Figure 1-2As shown in Embodiment 1, a magnetic aeration device mounted on an unmanned vessel includes a hull 7, which is made of steel. Aluminum alloy slide rails 8 are symmetrically installed on both sides of the hull 7. The slide rails 8 are fixed to the side plates of the hull 7 by bolts. A guide groove is opened on the inner side, which matches the raised structure of the base of the blower 4. The raised structure slides along the slide rail 8. Two parallel copper conductive strips 13 are embedded inside the slide rail. The conductive strips 13 are isolated from the slide rail body by an insulating pad, and their ends are connected to the positive and negative terminals of the battery pack 1 at the stern of the vessel.

[0023] Furthermore, the base of the fan 4 is welded with a neodymium iron boron permanent magnet 10, the magnet 10 is embedded in the slide rail 8, and the corresponding position of the slide rail 8 is embedded with an electromagnetic lock module 11. When the fan 4 is inserted into the slide rail 8, a strong magnetic attraction is formed to lock the fan 8 after power is applied. Pressing the mechanical release button on the outside of the slide rail 4 can cut off the power of the electromagnetic lock 11. The fan 4 can be disassembled and assembled manually by pushing and pulling along the slide rail. Limiting blocks 12 are provided at both ends of the slide rail 8 to prevent the fan 4 from falling out.

[0024] The fan 4 is connected to the slide rail 8 via the universal adjustment module 9, which includes a dual-axis universal adjustment module. The pitch angle adjustment is achieved by the universal adjustment module 9 rudder disk driving the bevel gear set, and the horizontal angle adjustment is achieved by the transverse lever mechanism, which controls the rotation of the horizontal axis of the universal adjustment module through the linkage transmission.

[0025] Furthermore, the bottom of the base of the fan 4 is provided with two sets of copper elastic contacts, which are pressed and connected with the conductive strip 13 when inserted into the slide rail 8, so as to transmit DC power to the relay 3. Waterproof parallel interfaces are provided at both ends of the slide rail 8.

[0026] Furthermore, the ends of the slide rail 8 are rigidly and stably connected to the hull 7 frame by bolts at the connection points, ensuring that the angle of the fan 4 remains stable when the hull 7 sways due to waves or turning.

[0027] The specific embodiment of this utility model is as follows: In a crab farming pond, the operator deploys the magnetic quick-release multi-adjustable blower aeration boat in the center of the water area. The slide rails 8 on both sides of the hull 7 are fixed with bolts. The guide groove on the inner side of the slide rail 8 precisely matches the protruding structure of the blower 4 base to ensure smooth sliding without deviation. The electromagnetic lock module 11 embedded in the slide rail 8 attracts the neodymium iron boron permanent magnet 10 of the blower 4 base after being powered on, locking the position. The operator manually rotates the rudder of the universal adjustment module 9 to drive the bevel gear set, adjusts the pitch angle of the blower 4 to -25°, and horizontally moves the lever mechanism to make the blower 4 horizontally deflect 30°, injecting directional airflow into the low-oxygen area of ​​the water.

[0028] When dissolved oxygen levels are insufficient in the northwest region due to accumulated aquatic plants, fan 4 operates at 5800 rpm. Airflow passes through the porous aeration pipe 6 connected to the PVC hose 5, impacting the bottom water and promoting the decomposition of sludge microorganisms. If fan 4 malfunctions, the operator presses the release button on the slide rail 8 to cut off the power to the electromagnetic lock 11, pulls out the faulty fan 4 along the slide rail 8, cleans the oxide layer on the conductive strip 13, and inserts the backup fan. Replacement is completed within 10 seconds without interruption. A waterproof parallel interface at the end of the slide rail 8 allows for the installation of a second fan 4.

[0029] In river management, the main vessel's blower 4 is adjusted to a -30° downward angle to directly spray sediment from the riverbed, while the auxiliary vessel horizontally covers the upper water layer. The auxiliary vessel 7 is manually towed to adjust its spacing to match the river width. The battery pack 1 at the stern of vessel 7 provides 10 hours of continuous operation per day. During maintenance, the universal adjustment module gear set is regularly lubricated to ensure smooth angle adjustments. This device achieves rapid deployment and precise aeration through a magnetic quick-release structure, multi-directional adjustment, and mechanical linkage via a sliding rail conductive power supply, making it suitable for large-scale aquaculture and polluted river management scenarios.

[0030] The working principle of this utility model is as follows:

[0031] In use, the hull 7 floats on the water, and the battery 1 provides power to the hull. The aluminum alloy slide rails 8 installed on both sides of the hull 7 cooperate with the raised structure of the fan 4 base through guide grooves to ensure that the fan 4 slides along the slide rails 8 without deviation. The electromagnetic lock module 11 embedded in the slide rail 8 is attracted and locked to the neodymium iron boron permanent magnet 10 of the fan 4 base. After pressing the release button, the power is cut off and the magnetization is demagnetized. The fan 4 can be quickly disassembled and assembled by pushing and pulling manually. The fan 4 is connected to the slide rail 8 through the universal adjustment module 9. The operator can manually rotate the universal adjustment module 9. The steering wheel drives the bevel gear set, which in turn adjusts the pitch angle of the blower 4 by ±30°. Each rotation corresponds to a 10° angle change. Laterally, the lever mechanism of the universal adjustment module 9 is activated, controlling the horizontal rotation by ±45° via linkage transmission. Directional airflow is injected into the low-oxygen area. The conductive strip 13 inside the slide rail 8 is pressed against the elastic contact at the bottom of the blower 4, transmitting 48V DC power to the relay 3. The parallel interface at the end supports extended power supply for dual blowers 4. Both ends of the slide rail 8 are bolted to the hull 7 to maintain stable aeration direction. During river management, operators manually pull the two boats apart, adjusting the main boat's blower 4 to -30°. The blower's end is connected to a PVC hose 5, with the hose head connected to a multi-hole inflation pipe 6, impacting the water at a downward angle. During maintenance, the faulty blower is removed, the conductive strip 13 is cleaned, and the backup blower is replaced. The universal adjustment module gear set is lubricated periodically. This design achieves rapid deployment, multi-angle aeration, and stable operation through pure mechanical linkage, suitable for oxygenation needs in complex waters.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
