AI Technical Summary
Traditional underwater vehicles generate strong wake vortices and turbulence when navigating underwater, resulting in high noise levels and affecting stealth capabilities.
The propeller blades of the left and right propeller nacelles rotate simultaneously to generate horizontal thrust in the same direction, avoiding disturbance to the water. Combined with the design of the propeller nacelle for navigation, this achieves low-noise navigation.
It enables the submersible to operate efficiently and covertly underwater with low noise and low disturbance, maintaining the equipment's balance and stealth.

Abstract
Description
A type of submersible that does not disturb the water. Technical Field
[0001] This invention relates to underwater vehicle technology, and more specifically to an underwater vehicle that does not disturb the water. Background Technology
[0002] Submersibles are specialized devices that can navigate or operate autonomously underwater. Traditional submersibles typically move forward by disturbing the water to the point where the water flows in the opposite direction, thereby generating strong wake vortices and turbulence, causing significant noise and affecting the stealth of the submersible. Summary of the Invention
[0003] The purpose of this invention is to provide a submersible that does not disturb the water body, in order to solve the problem that traditional submersibles usually disturb the water body to the point that the water body flows in the opposite direction and then the submersible moves in the forward direction, thereby generating strong wake vortices and turbulence, causing a lot of noise and affecting the stealth of the submersible.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a submersible that does not disturb the water body, comprising a control cabin, a left-hand propulsion cabin, a right-hand propulsion cabin, and a navigation direction propulsion cabin, which are interconnected to form a submersible.
[0005] The control cabin is equipped with control devices, functional devices, and remote control receivers, which are connected and transmitted via cables. The spiral blade sleeve surrounding the left spiral power cabin is tightly fitted onto the hub motor housing on the left spiral power cabin body, and the hub motor drives the spiral blade sleeve to rotate to the left. The spiral blade sleeve surrounding the right spiral power cabin is tightly fitted onto the hub motor housing on the right spiral power cabin body, and the hub motor drives the spiral blade sleeve to rotate to the right. The navigation direction power cabin has a transverse water flow hole in the middle of the closed cone shape. There is a shaftless pump thruster in the hole. The rotation of the shaftless pump thruster generates water flow thrust, changing the navigation direction. There is one shaftless pump thruster at the bow and one at the stern of the submersible.
[0006] Furthermore, the spiral blade sleeves surrounding the left and right spiral propulsion compartments rotate simultaneously, generating horizontal thrust in the same direction without disturbing the forward movement of the underwater vehicle.
[0007] This also prevented the submarine from capsizing and maintained its balance.
[0008] Compared with the prior art, the present invention provides a submersible that does not disturb the water body. By rotating the spiral blade sleeves around the left and right spiral propulsion chambers simultaneously, horizontal thrust is generated in the same direction, allowing the submersible to move forward without disturbing the water body, thus achieving efficient and low-disturbance stealth navigation.
