Abstract

The invention discloses an underwater dragging protection cabin. The dragging protection cabin consists of a traction rope, a watertight pressure-resistant shell, a cabin cover, a quick-release clamp, a stable section and a waterproof soft package. When the dragging protection cabin is used, nonwatertight and non-pressure-resistant equipment is firstly packed into the waterproof soft package, then the waterproof soft package is placed into the cabin body, and the cabin cover is covered. And hanging the dragging protection cabin to the tail part of the propeller by using a traction rope. When a frogman operates the propeller to navigate underwater, the dragging protection cabin drags with the propeller to dive. Upon reaching the destination, the frogman can manually open the hatch without the use of tools, taking out the equipment needed to perform the task. The dragging protection cabin has the functions of quickly dismounting and mounting the cabin cover, ensuring sealing and resisting water pressure, dragging and navigating stably and the like, and has very important function when a frogman carries out underwater diving and executes special tasks.

Description

Underwater towing protection cabin

Technical Field

The invention relates to an underwater dragging protection cabin, and belongs to the field of underwater equipment.

Background

When a frogman needs to dive underwater and executes a special task, a propeller is generally used for carrying the frogman and accompanying equipment in order to save physical strength and improve diving speed, and the depth of the frogman diving is generally in the range of 5-30 meters. With the increasing variety of tasks, some special tasks need to carry equipment without a watertight function, or some devices with a watertight function have no water pressure resistance. During the course of a dive, it is likely to cause equipment failure or damage. Therefore, the equipment protection cabin body with the water-tight and water pressure-resistant functions is designed, the cabin body is convenient to drag and navigate underwater, can be quickly disassembled and assembled without using tools, and can take out the equipment from the cabin body without damaging the equipment under the condition of not going to shore.

The watertight pressure-resistant shell and the hatch cover are both made of aluminum alloy materials, and the surface of the watertight pressure-resistant shell and the hatch cover is subjected to hard anodizing treatment.

Further, an airtight inspection port and a water inlet screw are integrated on the cabin cover;

further, the air tightness inspection port is sealed and plugged by a plug and an O-shaped rubber sealing ring, the plug is disassembled when the air tightness inspection device is used, an air tightness inspection tool is installed at the thread position, and the cabin body is pressurized to inspect the sealing performance of the dragging protection cabin;

furthermore, the water inlet screw is used for opening the hatch cover underwater (in a shallow water area), the screw and the hatch cover are sealed by using the end face of the O-shaped rubber sealing ring, four water inlet grooves are processed at the thread of the screw, water can enter the hatch cover by loosening the screw, and when the internal pressure and the external pressure are balanced, the hatch cover can be easily opened underwater to take out internal articles.

The quick-release clamp consists of two semicircular clamping rings, a connecting block, a stainless steel buckle and a pull ring split pin;

furthermore, two inclined planes are processed on the inner side surfaces of the two semicircular clamping rings, and when the cabin cover and the cabin body are connected through the tensioning buckle, the inclined plane matching part can be pulled more and more tightly, so that the connection reliability is ensured.

Furthermore, a stainless steel buckle is used for tensioning the two semicircular rings connected with the quick-release clamp;

further, in order to prevent the buckle from being loosened by accident, the pull ring split pin is installed at the buckle, a ring which can be inserted by fingers is designed at the front end of the pull ring split pin, and an operator can pull the split pin open by hand conveniently to loosen the buckle.

Four rudder plates are uniformly welded on the conical surface of the stabilizing section, and a balancing weight can be installed on the mandrel in the stabilizing section and is locked and fixed by a nut.

Furthermore, the stabilizing section shell is directly installed on the rear end face of the cabin body by using screws.

Further, the balancing weight appearance is the same, uses different materials such as lead block, plastics to make, can adjust the position of arranging at will, and the balancing weight of changing different materials adjusts whole buoyancy and the gesture in the aquatic that pulls the protection cabin, makes it be fit for pulling the navigation.

Detailed Description

The technical solution of the present invention is described in detail and completely with reference to the accompanying drawings, and obviously, the described embodiments are only a part of the embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the specific embodiment of the invention, the underwater dragging protection cabin mainly comprises a watertight pressure-resistant shell (3), a cabin cover (1), a quick-release clamp (2), a stable section (4), a waterproof soft bag (8) and a traction rope (5).

The cabin cover (1) is connected and fixed with the cabin body (3) through the quick-release clamp (2), the cabin cover (1) and the watertight pressure-resistant shell (3) are sealed by using an inclined plane of an O-shaped rubber sealing ring, and the stabilizing section (4) and the cabin body are connected and fixed through screws.

The hatch cover (1) is integrated with a water inlet screw (8), an airtight plug (7) and a lifting ring screw (6). The water inlet screw (8) and the air-tight plug (7) are sealed with the cabin cover (1) by O-shaped ring end faces, and the water inlet screw (8) can be unscrewed to feed water into the cabin body through a water inlet hole on the screw, so that balance of internal pressure and external pressure is ensured, and the cabin cover (1) can be opened in a shallow water area.
