Description

Technical Field

[0001] The present invention relates to the technical field of underwater power equipment, and in particular to a tilt-vector underwater power device. Background Art

[0002] The total area of ​​the world's oceans is about 360 million square kilometers, accounting for about 71% of the earth's surface area, with an average water depth of about 3,795 meters. It has rich resources. Therefore, the exploration of the ocean has great scientific research value and national defense value. The marine environment is complex and has various hydrological conditions. In recent years, underwater diving technology has developed rapidly and can be divided into manned submersibles and unmanned submersibles. Manned submersibles such as submarines require space for personnel activities, so most of them are large in size and have poor maneuverability in a small space, and cannot maneuver quickly in a complex underwater environment; unmanned submersibles have the advantages of small size and low cost. Most of them use tail power drive, which also has the problem of poor maneuverability in complex underwater spaces. Therefore, in complex water environments, it is very necessary to develop a highly maneuverable, small-volume power device.

[0003] The tilt-vector power structure has great advantages. For example, the tilt-rotor structure used by the US Osprey V-22 aircraft combines the flexibility of a helicopter with the high speed and long-range advantages of a fixed-wing aircraft. Its maximum speed exceeds 500 kilometers, its cruising speed is close to 400 kilometers, and its range can reach 1,600 kilometers. It has advantages far exceeding the performance of helicopters. Therefore, the independent development of a tilt-vector underwater power device is of great significance compared to traditional underwater propulsion methods. Summary of the invention

[0004] The purpose of the present invention is to provide a tilt-vector underwater power device which can realize ultra-high maneuverability of an underwater submersible.

[0005] In order to achieve the above object, the technical solution specifically adopted by the present invention is as follows:

[0006] A tilt vector underwater power device includes an outer cabin, a core cabin, and a group of propeller propulsion structures symmetrically installed on the core cabin. The propeller propulsion structure includes gears, a steering gear, a rotating shaft, and a propeller propeller. One end of the rotating shaft is connected to the steering gear through a gear, and the other end passes through the core cabin and the outer cabin in sequence, and extends to the outside of the outer cabin and is connected to the propeller propeller. A bearing and a bearing oil seal are installed at the junction of the rotating shaft and the core cabin, and are co-positioned with the rotating shaft through left and right end covers. A rotating shaft oil seal is installed on the part of the rotating shaft in the outer cabin, and is co-positioned with the rotating shaft through left and right end covers. When in use, the steering gear drives the gear to rotate, the gear drives the rotating shaft to rotate, and then drives the propeller propeller to rotate around the axis. At this time, starting the propeller propeller can provide power with a tilt vector, which will greatly improve the maneuverability of the underwater equipment.

[0007] Furthermore, the core cabin is placed in the outer cabin, and the steering gear is directly connected to the gear and both are fixed in the core cabin.

[0008] Furthermore, the edges of the left and right end covers are both provided with through holes, and are installed on the outer cabin body through threaded connection. At the same time, grooves are left on the side walls thereof, which cooperate with O-rings for external sealing.

[0009] Furthermore, a through hole is opened on the rightmost end of the rotating shaft, and a corresponding hole is also opened on the outside of the propeller propeller, and the propeller propeller is installed on the rotating shaft by plugging bolts.

[0010] Furthermore, it also includes a gasket with a hole, which is installed between the core module body and the sealing cover of the core module body and is connected to the core module body by screws to further improve the waterproof performance of the power unit.

[0011] The present invention has the following characteristics and beneficial effects:

[0012] The tilt vector underwater power device of the present invention can realize the ultra-high maneuverability of underwater submersibles. In principle, it can realize maneuverability that traditional submersibles cannot achieve, such as turning around on the spot, flipping and other difficult actions. It plays a very important role in improving the performance of underwater submersibles. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0019] like Figure 1-Figure 2 As shown, a tilt-vector underwater power device according to an embodiment of the present invention comprises an outer cabin 1, a core cabin 2 and a group of propeller propulsion structures symmetrically installed on the core cabin 2, the propeller propulsion structure comprising a gear 6, a steering gear 7, a rotating shaft 8 and a propeller propeller 10, one end of the rotating shaft 8 is connected to the steering gear 7 through the gear 6, and the other end passes through the core cabin 2 and the outer cabin 1 in sequence, and extends to the outside of the outer cabin 1 and is connected to the propeller propeller 10. When in use, the steering gear 7 drives the gear 6 to rotate, and the gear 6 drives the rotating shaft 8 to rotate, thereby driving the propeller propeller 10 to rotate around the axis. At this time, starting the propeller propeller 10 can provide power with a tilt vector, which will greatly improve the maneuverability of the underwater equipment.

[0020] In this embodiment, the core cabin 2 has an external electrical connection port, which can interact with the outside world for control information and perform unidirectional power transmission to power the motor. The outer cabin 1 can be modified in the installation structure to meet the needs of different application scenarios, such as being changed into a handheld type as an underwater booster; or integrated with other underwater robots to improve the maneuverability of the robot. The core cabin 2 is placed in the outer cabin 1, and the steering gear 7 is directly connected to the gear 6, and both are fixed in the core cabin 2; the bearing 3 and the bearing oil seal 4 are installed at the junction of the rotating shaft 8 and the core cabin 2, and are co-positioned with the rotating shaft 8 through the left and right end covers 5; the rotating shaft 8 is installed with a rotating shaft oil seal 9 in the outer cabin 1, and is co-positioned with the rotating shaft 8 through the left and right end covers 5. The edges of the left and right end covers 5 are both provided with through holes, which can be installed on the outer cabin 1 through threaded connection, and the side walls thereof are provided with grooves, which can be used with O-rings for external sealing.

[0021] In order to further improve the waterproof performance of the power device, a gasket 11 is also included. The gasket 11 has a hole and is installed between the core module body and the sealing cover of the core module body 2. The gasket is connected to the core module body by screws to further improve the waterproof performance of the power device.

[0022] In this embodiment, a through hole is opened on the rightmost end of the rotating shaft 8, and there are corresponding holes on the outside of the propeller propeller 10. The propeller propeller 10 can be installed on the rotating shaft 8 by plugging bolts.

[0023] In this embodiment, a group of propeller propulsion structures are arranged horizontally and symmetrically, and by adjusting the rotation angles of different propeller propellers 10, a variety of vector power can be provided, such as Figure 3As shown, when both the left and right propeller thrusters 10 are facing downward, the forward rotation of the propeller can provide upward lift, and the reverse rotation can provide downward pulling force; when one of the left and right propeller thrusters 10 is facing forward and the other is facing backward, when the propellers rotate in the same direction, a force couple will be generated around the center point of the device. This force couple will cause the device to rotate around its center point without causing overall translation. Specifically, assuming that the left propeller rotates counterclockwise and the right propeller rotates clockwise, the thrust directions they generate will be opposite, and the resultant force of the thrust will mainly act on the rotational force couple rather than the horizontal propulsion force. The offset of the point of action will cause a rotational force couple to be generated around the center point of the power device. Under the action of this force couple, the device can rotate in situ underwater.

[0024] This specific implementation uses a symmetrically distributed double-propeller propulsion structure, in which the propeller propeller 10 is combined with the intermediate steering gear 7 through an axis to achieve the function of the propeller propeller 10 being rotatable as a whole, so that the device can adjust different rotation angles of the propeller propeller 10 to make the power have a tilt vector characteristic.

[0025] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
