Description

Technical Field

[0001] This utility model relates to the field of underwater vehicle technology, and in particular to a rapid trim device for small underwater vehicles. Background Technology

[0002] Motor-driven automatic trimming device: This is currently a more advanced technology. Its core is a motor-driven lead screw that moves a slider along a rail. Counterweights can be placed on the slider to adjust the center of gravity. Some more complex systems integrate buoyancy adjustment mechanisms (such as pistons or oil bladders) and center of gravity adjustment mechanisms (such as moving sliders), achieving automatic or semi-automatic buoyancy and attitude balance through a controller. This type of technology typically requires complex control systems, sensors, and drive components, with the structure integrated inside the aircraft compartment.

[0003] External adjustable balancing structure: This is a relatively traditional mechanical solution. For example, a bracket that slides along a guide rail is installed on top of the diving equipment. The bracket has a tray or container for placing counterweights and can be connected to additional counterweights or buoyancy materials. The balance of the equipment is adjusted by manually sliding the bracket and fixing its position, or by adding or removing counterweights on the tray. This method involves an exposed structure and requires manual operation for adjustment.

[0004] Complex structure, high cost, and large space occupation. Electric motor-driven solutions and hydraulic / oil bladder buoyancy adjustment systems require the integration of motors, lead screws, slide rails, pumps, valves, seals, and complex control systems. This not only significantly increases manufacturing costs and failure rates but also squeezes the already precious internal space and payload capacity of small aircraft.

[0005] The adjustment process is cumbersome and time-consuming, making "rapid matching" impossible. Whether it's manual adjustment of external guide rails, adjustment of counterweights requiring disassembly of the engine compartment, or reliance on software calculations and automatic motor execution, the entire balancing process is quite complicated. Especially when the mission load changes frequently, each time it requires recalculation, disassembly, or execution of the automatic adjustment program, failing to achieve a "quick and easy" response.

[0006] Poor adaptability and limited versatility. Complex integrated devices are often deeply tied to specific aircraft models, making them difficult to port to other platforms. While external structures are relatively independent, they are typically designed with fixed dimensions, making it difficult to flexibly adapt to various load combinations with different shapes, sizes, and trim requirements. Utility Model Content

[0007] The purpose of this invention is to overcome the problems of existing trimming devices, such as complex structure, high cost, large space occupation, cumbersome and time-consuming adjustment process, poor adaptability, and weak versatility, and to provide a rapid trimming device for small underwater vehicles.

[0008] To achieve the above objectives, this utility model employs the following technical solution:

[0009] A rapid trimming device for a small underwater vehicle includes a counterweight ball filling hopper, a magnetic buoyancy standard block, a magnetic base, a counterweight ball guide tube, a self-weight float, fasteners, a counterweight ball storage chamber, a vehicle connection interface, a bottom cover, and a counterweight ball. The counterweight ball storage chamber has a counterweight ball guide tube on each of its left and right sides. The counterweight ball filling hopper is connected to the end of the counterweight ball guide tube and connects to the interior of the counterweight ball storage chamber through the guide tube. A magnetic base is welded to the counterweight ball guide tube, and the magnetic buoyancy standard block is magnetically attracted to the magnetic base. The self-weight float is fixed to the left and right sides of the counterweight ball storage chamber by fasteners and is located below the counterweight ball guide tube. The bottom of the counterweight ball storage chamber has an openable and closable bottom cover, and the top of the counterweight ball storage chamber has a vehicle connection interface for connection to the vehicle.

[0010] Furthermore, the magnetic base can attract multiple magnetic buoyancy standard blocks.

[0011] Furthermore, the counterweight ball storage chamber is provided with water-permeable holes.

[0012] Furthermore, the counterweight ball is a steel ball or lead ball counterweight ball.

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

[0014] 1. It achieves convenient operation and rapid balancing. By using magnetic buoyancy standard blocks and adding counterweight balls, the buoyancy and gravity modules can be installed and removed in seconds; the counterweight is adjusted by adding or removing counterweight balls, and the operation is as intuitive as "doing addition". The entire balancing process has been simplified from the traditional cycle of "calculation-disassembly-adjustment" to three steps of "evaluation-attachment-addition / reduction", reducing the balancing time from several hours to several minutes, and truly achieving "fast and efficient balancing".

[0015] 2. Extremely simplified structure, significantly reducing cost and failure rate. It completely eliminates expensive and easily damaged motion and control system components such as motors, lead screws, slide rails, hydraulic pumps, and solenoid valves. The entire device consists only of a simple magnetic base, a self-weighting float, a counterweight ball storage chamber, and a counterweight ball. The structure is reliable, with virtually no points of failure, and extremely low manufacturing costs, making it ideal for small platforms used in low-cost, high-volume applications.

[0016] 3. Maximizes space saving and enhances adaptability. The device is installed close to the bulkhead, occupying almost no valuable core space inside the cabin. Its modular design offers strong versatility; the same device can be adapted to different models and missions of small aircraft. Users can freely combine different numbers and positions of modules as needed to flexibly address ever-changing trim requirements. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0021] Example:

[0022] like Figure 1-2 As shown, this utility model provides a rapid trimming device for a small underwater vehicle, including a counterweight ball filling hopper 1, a magnetic buoyancy standard block 2, a magnetic base 3, a counterweight ball guide tube 4, a self-weight float 5, fasteners 6, a counterweight ball storage chamber 7, a vehicle connection interface 8, a bottom cover 9, and a counterweight ball. The counterweight ball storage chamber 7 has a counterweight ball guide tube 4 on each of its left and right sides. The counterweight ball filling hopper 1 is connected to the end of the counterweight ball guide tube 4, and the counterweight ball guide tube 4 connects to the interior of the counterweight ball storage chamber 7. The magnetic base 3 is welded to the counterweight ball guide tube 4, and the magnetic buoyancy standard block 2 is magnetically attracted to the magnetic base 3. The self-weight float 5 is fixed to the left and right sides of the counterweight ball storage chamber 7 by fasteners 6, and the self-weight float 5 is located below the counterweight ball guide tube 4. The bottom of the counterweight ball storage chamber 7 is provided with an openable and closable bottom cover 9, and the top of the counterweight ball storage chamber 7 is provided with a vehicle connection interface 8 for connection to the vehicle 10.

[0023] Specifically, the magnetic base 3 can attract multiple magnetic buoyancy standard blocks 2.

[0024] Specifically, the counterweight ball storage chamber 7 is equipped with water-permeable holes.

[0025] Specifically, the counterweight ball is a steel ball or lead ball.

[0026] In this embodiment, when the underwater vehicle 10 is in an unbalanced state due to the change of mission load, the operator can quickly perform the following steps: (1) adsorb 2-4 magnetic buoyancy standard blocks 2 on one side of the small underwater vehicle quick trim device to increase buoyancy; (2) add some counterweight balls as needed on the other side of the small underwater vehicle quick trim device to increase the equivalent weight. Through this combination of "reducing weight on one end and increasing buoyancy on the other end", trimming can be completed in a few minutes without any tools or complex calculations, achieving "fast and efficient trimming".

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
