[0002] With the continuous development of marine resources and the increasing complexity of the marine environment, fields such as marine exploration, environmental monitoring, and underwater scientific research are becoming increasingly reliant on remotely operated vehicles (ROVs). As a device capable of long-duration, highly flexible underwater operations, ROVs have become an indispensable tool in these fields.
[0003] Traditional ROV designs typically use a combination of propellers and servos to achieve underwater movement. However, this design has limited adaptability and maneuverability in complex underwater environments. For example, under the same power input, a six-propeller layout exhibits a higher energy efficiency ratio than an eight-propeller layout. This is because the number of propellers is moderate, avoiding excessive energy dispersion and redundancy. However, its flexibility is reduced compared to an eight-propeller layout.
[0004] Therefore, in the above-mentioned technology, the layout and number of propellers are further improved and a multi-propeller aircraft is proposed. Utility Model Content

By reducing water resistance and simplifying the mechanical structure, the energy consumption of the aircraft is reduced, thus improving the energy efficiency ratio. At the same time, through the innovative seven-propeller design, the aircraft can achieve omnidirectional movement, including forward, backward, ascent, descent, and left and right movement, thereby achieving efficient propulsion and flexible control.

The various embodiments of this utility model are described in detail below with reference to the accompanying drawings. Example 1
[0030] Please see Figures 1 to 7The present invention preferably provides the following technical solution: a multi-propeller aircraft, comprising: a carrier body, the carrier body being hollowed out; and a first propeller 211, a second propeller 212, and a third propeller 213 mounted on the carrier body, the first propeller 211, the second propeller 212, and the third propeller 213 being assembled perpendicular to the carrier body and in a triangular distribution for controlling the up-down and flipping movements of the carrier body; further comprising a fourth propeller 311, a fifth propeller 312, a sixth propeller 313, and a seventh propeller 314 mounted on the carrier body, the fourth propeller 311, the fifth propeller 312, the sixth propeller 313, and the seventh propeller 314 being spatially distributed at 45° at the four corners of the carrier body for controlling the forward-backward and left-right movements of the carrier body;
[0031] Furthermore, the first propeller 211, the second propeller 212, the third propeller 213, the fourth propeller 311, the fifth propeller 312, the sixth propeller 313, and the seventh propeller 314 have the same structure and principle, and are each equipped with an independent motor and control unit. The control unit controls the speed and direction of the corresponding propeller.
[0032] In this application, the hollowed-out design of the aircraft body and the regular symmetrical flattened structure reduce water resistance and simplify the mechanical structure, thereby reducing the energy consumption of the aircraft and improving its energy efficiency ratio. At the same time, the innovative seven-propeller design, with the first propeller 211, the second propeller 212, the third propeller 213, the fourth propeller 311, the fifth propeller 312, the sixth propeller 313 and the seventh propeller 314 being existing mature technologies, is driven by independent brushless motors. These motors are controlled by precise electronic speed controllers (ESC). By independently controlling the speed and propulsion direction of each propeller, the aircraft can achieve omnidirectional movement, including forward, backward, ascent, descent and left and right movement, thereby achieving efficient propulsion and flexible control.
[0033] Specifically, if Figure 6 As shown, in the forward-moving state, the fourth propeller 311, the fifth propeller 312, the sixth propeller 313, and the seventh propeller 314 are operating and propulsing according to the arrows shown in the figure; as... Figure 7 The diagram shows the leftward movement in the forward direction. Similarly, the backward and rightward movements can also be performed.
[0034] When the operation of the first propeller 211, the second propeller 212, and the third propeller 213 is controlled and the propulsion direction is controlled, the machine can ascend and descend. When the propulsion directions of the second propeller 212 and the third propeller 213 are opposite, a torque will be generated, causing the machine to flip left and right.
[0035] Furthermore, the aircraft body includes a first frame 112 and a second frame 111 disposed below the first frame 112, and also includes several connecting fittings 150 for detachably mounting the second frame 111 and the first frame 112.
[0036] Furthermore, a first mounting cavity 116, a second mounting cavity 117, and a third mounting cavity 118 are perpendicular to the first frame 112. These three mounting cavities are triangularly distributed and are respectively used for mounting the third propeller 213, the first propeller 211, and the second propeller 212 via mounting members 411. Figure 1 As shown, the first mounting cavity 116, the second mounting cavity 117 and the third mounting cavity 118 are circular holes for embedding the third propeller 213, the first propeller 211 and the second propeller 212, which can be placed perpendicular to the ship body.
[0037] Furthermore, the support side rods 130 fixed at the four corners of the second frame 111 are used to install the fourth propeller 311, the fifth propeller 312, the sixth propeller 313 and the seventh propeller 314 at the corresponding positions. Example 2
[0038] As another embodiment of this utility model, the head and tail sections of the hull are respectively provided with a head compartment 113 and a tail fin 119, and the hull adopts a regular symmetrical flat design, which reduces the cross-sectional area and reduces the shear force formed by water flow on the surface of the vehicle, thereby reducing hydrodynamic drag.
[0039] Furthermore, the first hollowed-out groove 114 and the second hollowed-out groove 115, which are symmetrically distributed around the head of the aircraft body, are used to reduce weight and reduce drag caused by turbulence. Example 3
[0040] In other embodiments of this utility model, depth sensors, attitude sensors, sonar systems and high-definition cameras are evenly distributed on the second frame 111 and the first frame 112 where the vehicle body is located. Through the set sensing units and camera modules, real-time underwater environmental data can be provided to help the operator better understand the situation around the vehicle.
[0041] Furthermore, it also includes a fourth mounting cavity 120 located at the tail of the aircraft body. The fourth mounting cavity 120 is equipped with an electronic placement compartment 611. The electronic placement compartment 611 has a streamlined design at the tail and integrates a control system, a communication module, a navigation system, and a sensor suite for comprehensive remote control and data transmission of the aircraft.
[0042] The internal structure of the electronic storage compartment 611 is divided into upper and lower layers. The lower layer is specifically used to house heavier electrical components to ensure stability and maneuverability during underwater operations. The remaining related electrical components are rationally placed in the upper space, maximizing space utilization. In the communication system, this invention adopts a high-bandwidth, low-latency communication system to ensure stable and reliable data transmission between the vehicle and the operator. The communication system supports multiple communication protocols, including wireless and wired communication, to adapt to different operating environments.
[0043] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit method, or by using a bolt connection, etc.
[0044] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
