Description

Technical Field

[0001] The present invention relates to the technical field of submersibles, and specifically to a submersible. Background Art

[0002] An unmanned submersible, also known as an Unmanned underwater vehicle in English, is a device that operates underwater without a driver and is remotely controlled or automatically controlled. It mainly refers to those intelligent systems that replace divers or manned small submarines for high-risk underwater operations such as deep-sea exploration, rescue, and mine clearance. Therefore, unmanned submersibles are also known as "diving robots" or "underwater robots". Unmanned submersibles can be divided into military and civilian applications according to their application fields. In the military field, unmanned submersibles can be used as an unmanned combat platform weapon in new concept weapons. In a certain sense, the role of unmanned submersibles is similar to that of unmanned aerial vehicles. The traditional end fairing structure of submersibles has too much resistance during navigation, thus affecting the navigation speed of submersibles. Summary of the Invention

[0003] The purpose of the present invention is to provide a submersible, which solves the problem that the traditional end fairing structure of submersibles has too much resistance during navigation, thus affecting the navigation speed of submersibles.

[0004] Technical Solution

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A submersible includes a submersible body. A fairing structure is threadedly installed at the top of the submersible body. A grille structure is fixedly installed at the bottom of the submersible body. A tail cover is fixedly installed at the bottom of the grille structure. Flow guiding fins are fixedly arranged on the surface of the tail cover.

[0006] Further, the flow guiding fins are evenly distributed on the surface of the tail cover.

[0007] Further, sliding guide grooves are formed on the surface of the submersible body, and a sliding mounting frame is slidably connected inside the sliding guide grooves.

[0008] Further, fixing holes are preset on the sliding mounting frame.

[0009] Further, the inside of the fairing structure is designed with a triangular hollow.

[0010] The present invention provides a submersible, which has the following beneficial effects:

[0011] 1. The submersible vehicle, through the mutual cooperation of the flow guiding structure, grille structure, tail cover and flow guiding fins, reduces resistance during the navigation of the submersible vehicle, thereby improving the navigation speed and efficiency of the submersible vehicle, and solving the problem that the traditional end flow guiding structure of the submersible vehicle has too much resistance during navigation, thus affecting the navigation speed of the submersible vehicle.

[0012] 2. The submersible vehicle, through the setting of the sliding guide groove, sliding mounting frame and fixing holes, facilitates the installation of equipment outside it, thereby realizing the execution of tasks with specific requirements, and at the same time, it is also easy to adjust the position of the equipment.

[0014] Figure 2 is a transverse schematic diagram of the structure of the present invention.

[0015] Among them, 1 is the submersible vehicle body, 2 is the flow guiding structure, 3 is the sliding guide groove, 4 is the sliding mounting frame, 5 is the fixing hole, 6 is the grille structure, 7 is the tail cover, and 8 is the flow guiding fin. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] As Figure 1-2 shown, an embodiment of the present invention provides a submersible vehicle, including a submersible vehicle body 1. A sliding guide groove 3 is provided on the surface of the submersible vehicle body 1. A sliding mounting frame 4 is slidably connected inside the sliding guide groove 3. Fixing holes 5 are preset on the sliding mounting frame 4. A flow guiding structure 2 is threadedly installed at the top of the submersible vehicle body 1. The inside of the flow guiding structure 2 is designed with a triangular hollow. A grille structure 6 is fixedly installed at the bottom of the submersible vehicle body 1. A tail cover 7 is fixedly installed at the bottom of the grille structure 6. Flow guiding fins 8 are fixedly arranged on the surface of the tail cover 7, and the flow guiding fins 8 are evenly distributed on the surface of the tail cover 7.

[0018] Working principle: When the submersible vehicle is navigating, the propulsion system pushes water outwards from the inside of the grille structure 6. The water flow is first split by the flow guiding structure 2, and then the water flow is split by the tail cover 7 and the flow guiding fins 8, thereby reducing the resistance of the water to the submersible vehicle and thus increasing the speed.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
