Abstract

FIELD: diving equipment.

SUBSTANCE: invention relates to diving equipment and can be used for diving and underwater work at depths. The combined diving wetsuit has in its design a rigid incompressible shell, a corset made of metal or polymer and composite materials, which is a shell with holes for the arms, legs and head, completely covering the swimmer’s torso from neck to legs, with a fixed diving helmet made of durable transparent glass or polycarbonate and soft (compressible) sleeves and legs made of waterproof elastic material hermetically attached to the wetsuit.

EFFECT: minimization of decompression time during ascent is achieved, as well as the risk of barotrauma is reduced and the overall productivity of diving operations increases.

Description

The modern exploration of the world's oceans requires penetration into its depths. The demand for diving works is growing every year. Offshore development, prospecting, construction, repair and lifting of ships requires the constant presence of a person under water. Unfortunately, the environment is aggressive, with its high pressure and low temperatures requiring a person to have protective equipment. Breathing underwater remains a priority.

Of course, recently, the direction of unmanned robotic underwater vehicles has been actively developing, but, unfortunately, they are unable to solve the entire range of tasks. In addition, the cost of such devices is prohibitively high, so only large, wealthy enterprises and the military can afford them.

Rigid normobaric spacesuits allow you to stay under water for a long time and ascend without decompression. But then again, heavy, bulky spacesuits require complex support and cannot always perform tasks that are easily performed by swimmers in light equipment. And the cost of normobaric spacesuits is comparable to the cost of an airplane.

Therefore, the use of light diving equipment remains relevant, despite all its disadvantages.

The main problem with padded diving suits is that they do not provide chest protection against water pressure. The swimmer physically cannot take a breath, being already at a depth of 1 meter.

It becomes necessary to breathe air at high pressure, and with increasing depth, the pressure of the inhaled air increases. The gases contained in the inhaled air (nitrogen or helium in mixtures) dissolve in the swimmer's blood and tissues.

There is a supersaturation of the body with gas under pressure, which, when the pressure decreases (ascending), begins to be actively released, which leads to the diver's barotrauma.

To avoid this, the diver has to make a long ascent. And depending on the depth and duration of stay in the water, the ascent (decompression) time can significantly exceed the time spent on the ground, that is, the time of useful work.

The presented invention is intended to some extent to solve the problem of human breathing under water and is intended primarily for professional use.

The object of the invention is the possibility of breathing air under water, under pressure close to atmospheric.

The problem is solved by using a combined diving suit.

The combined diving suit consists of a rigid, incompressible carapace-corset that covers the swimmer's torso, a non-removable transparent diving helmet and flexible, elastic sleeves and legs.

The essence of the invention is as follows. A rigid (incompressible) shell-corset with a non-removable helmet protects the respiratory organs from external water pressure and allows you to breathe air under pressure close to atmospheric, in essence, being a normobaric spacesuit. At the same time, the flexible sleeves and legs of the wetsuit do not impede the movements of the swimmer and allow them to move and work freely underwater.

The transparent helmet and flexible sleeves and legs have a sealed and one-piece connection with the carapace corset.

Flexible sleeves and legs are made of durable, elastic, waterproof material. In the area of joining with a rigid corset, they have a gradually increasing thickness of the material, since under the pressure of water these places will experience maximum tensile stress.

The sleeves can be either one-piece, with a glove for the wrist, or have a sealed connector in the wrist area for a separately worn glove.

The legs can also have a one-piece construction that covers the legs completely, or have a sealed connector

for diving shoes.

The connector version makes it easier to don the suit, but complicates the design.

The costume is put on through a sealed connector in the belt area, which divides the rigid frame into upper and lower halves. The fixation of the belt connector can be different, both threaded and with eccentric latches.

A diving helmet is a transparent flask made of thick tempered glass or polyamide material, which is hermetically and immovably attached to a corset-shell. The connection of the helmet with the shell does not provide for its removal during operation, simplifying the design and increasing the reliability of the connection.

The size of the helmet allows you to rotate your head in all directions, excluding blind spots. The connector for supplying air from external cylinders is located in the back of the head of the helmet. The absence of a gearbox and breathing hoses in front of the diver's face does not block the view and does not interfere with the work.

The helmet additionally has an anti-fogging system and a microphone for communication with the surface.

On the back of the carapace-corset there are runner guides with locks for rigid fixation of air cylinders. This eliminates the need for ammunition for attaching cylinders.

In case of damage to the suit and water ingress, an emergency valve with manual and automatic activation is provided, which will raise the air pressure inside until the water is displaced from their helmet.

In this case, an emergency ascent with full decompression is performed.

The use of a combined diving suit will allow a diver to stay under water for a long time and minimize the time for decompression upon ascent, which in general will significantly increase the useful time for underwater work.

Also, the absence of overloads associated with decompression will have a positive effect on the health of the diver, his well-being and performance.

Disadvantages of the combo suit.

First of all, the inconvenience of the vestments. Putting it on yourself is very problematic, you need help. However, divers rarely work alone.

The second is an increase in buoyancy. Solved, as always, with lead weights.

The third is the need for individual adjustment of the suit to the figure of the swimmer. Therefore, the suit is intended primarily for professional divers. The equipment and supplies of which already cost a lot of money, against which the cost of an individual diving suit will not be critical.

Despite all the variety of diving equipment, there are no analogues to this invention known to the author. The only one similar in essence is the invention of the German Karl Klingert in 1797.
