Diving Helmet

The proposed device relates to diving equipment and for the manufacture of diving helmets designed to protect the diver's head from exposure to the aquatic environment and create comfortable conditions when working underwater.

Known diving helmet containing a rigid body with a porthole, connecting neck ring, handle, rear weighting system, life support system, consisting of nippers and main air supply valves (US patent No. 3958275 CL 63 C 01/11/1970). However, the design of this helmet does not provide for the placement of lighting and video equipment, as a result of which the diver holds them in his hands, which creates difficulties and inconveniences in the work of the diver.

Known diving helmet Sl-17b company Dimng at stems Int. Inc. (company prospectus 1999, p. 8), containing a rigid case with a porthole, a connecting ring for a drink, a handle, a rear weighting device and life support systems located on the case. The porthole holder has holes for fixing the lighting and video equipment.

However, in the well-known helmet, the rigid base of the case does not have reinforcements at the places of the greatest stress when hanging on w: lem of lighting and video equipment, which can lead to breakdowns of the case due to its fragility. In addition, the placement of equipment on the porthole holder increases the resistance of the aquatic environment when the diver moves.

This device, as the closest to the proposed structural and functional features, is taken as a prototype. The proposed design solves the problem of increasing the strength of the helmet while reducing the resistance of the aquatic environment when the diver moves.

To solve this problem in a well-known w: lem containing a rigid case with a porthole, a connecting neck ring, a handle, a rear weighting device and life support systems located on the body, on the helmet body under the handle, place; bonoks which are intended for fastening of boxing with the light and video equipment.

The utility model is illustrated by the drawing, which shows the design of the proposed helmet.

The inventive diving helmet contains: a body / with a handle 2, a rear weighting device 3, a porthole 4, a handle for the additional blower of the porthole 5, a side unit of the life support system 6, a handle for the regulator of the breathing apparatus 7, a handle for the reserve air supply valve, a non-return valve for supplying main air 9, automatic skiing 10, connecting neck ring //, neck clamp / 2, waterproof telephone jack / 3, a plate for mounting light and video equipment with holes for bonding bonok 14. Diving helmet works is as follows.

A diving helmet is put on a diver’s head, connected with a jumpsuit with a neck ring / / and secured with a neck clamp 12.

Air comes from an external source on the banks / through hoses (not shown in the drawing) through a fitting to the non-return valve 9 to the lung breathing machine 10 and is regulated by a diver with the help of the knob of the regulator of the breathing machine 7.

When fogging the windows of the porthole, the diver increases the airflow of the porthole using the handle of the blower valve 5.

In the event of an emergency, for example, due to interruption in the supply of main air as a result of a break or pinching of the air hose, the diver uses an emergency supply of compressed air from cylinders located behind the back using valve handle 8.

On the helmet body are located the rear weighting agent 3 and the side left and right (not shown in the drawing) for ba / ansling of the helmet when filling it with air. The diver carries out communication with the surface using a waterproof telephone connector 15.

On the helmet case, under the handle 2, there is a trapezoidal shaped platform 14 with holes, on which a box with light and video equipment is hung and fixed (not shown). The diver’s hands are completely free, which makes it easier for the diver to carry out underwater operations.

the proposed design allows to achieve the following technical effect:

 increase in durability of the diving helmet case due to creation of a trapezoidal shape under the handle, which reinforces the rigid base

housing; decrease in water resistance at

due to the compact placement on the body of the helmet under the handle of the box with light and video equipment;

 reduction of physical effort during movement creates favorable conditions for the diver.
