Said sprayer is connected with hose supplying water from diver's heating system. Orifices of sprayer are made in form of nozzles directed to inner glass. Drain holes are provided over perimeter of holder between glasses. EFFECT: avoidance of sweating of glasses; reduced level of noise. 2 dwg

Description

 The invention relates to diving helmets of diving equipment and can be used when conducting diving descents and works in diving units of the Navy, as well as other organizations engaged in diving operations and using diving equipment with water heating.

 A diving helmet is known in which a wiper is used to prevent fogging of the porthole glass (O.M Slesarev. Diving equipment of the Navy. M.: Military Publishing House, 1990, p.118). To prevent the window glass from fogging, the diver must periodically turn the wiper manually.

 The disadvantage of such a diving helmet is the need to divert the diver from the work performed to activate the wiper, reducing the view due to the wiper body, as well as incomplete cleaning of the window glass.

 The closest analogue of the claimed invention is a diving helmet, in which airflow is used to prevent window glass from fogging (ventilated diving equipment SVV-97 (OAO KAMPO, Orekhovo-Zuevo, 1998). Technical description and operating instructions 9B2 .930.380, p. 7. Diving helmet SVV-97 - prototype). The diving helmet contains a clip with a porthole and a perforated spray gun mounted inside the helmet with an attached air hose. Jets of air from the nozzle openings blow the glass inside the helmet and prevent the window from fogging.

 The disadvantage of this device is the additional consumption of air reserves, as well as the occurrence of noise inside the diving helmet, affecting the quality of communication, which ultimately affects the safety of diving descents and operations.

 The technical task of the claimed invention is to increase the efficiency and safety of diving descents and works by improving visibility by preventing fogging of the porthole glass of the diving helmet, as well as reducing noise.

 The specified technical result is achieved by the fact that in the proposed diving helmet the clip with a porthole consists of two glasses, between which there is a spray with a water supply hose connected to it from a diver’s water heating system, the spray holes are made in the form of nozzles directing water across the entire surface of the inner glass, and along the perimeter of the holder between the glasses there are drain holes. Water from the diver’s water heating system fills the space between the windows of the porthole of the diving helmet, heats them and prevents fogging.

 Schematic diagram of a diving helmet is presented in figure 1, front view; figure 2 is the same side view.

 Diving helmet 1 consists of a holder 2. Inside the holder fixed inner 3 and outer 4 glass. Between the glasses in the upper part of the holder 2 there is a sprayer 5 with nozzles 6 directed to the inner glass 3. A hose 7 for supplying water from a diver’s water heating system is connected to the sprayer. At the bottom of the cage 2 there are drain holes 8.

 In the idle state, the water supply from the diver’s water heating system is closed.

 The work of the diving helmet is as follows.

 After putting on the diving helmet and all the diving equipment, a hose 7 is additionally connected to the water heating system to supply water to the spray gun 5. When water is supplied from the water heating system of the diver, water through the hose 7 starts to flow to the spray 5 where it is evenly distributed along the entire length and then goes to nozzles 6 to the inner glass fills the inner space between the glasses 3 and 4, heats them and leaves the holder 2 through the drain holes 8 to the outside. In this case, the process occurs automatically and does not require diver's diversion, completely eliminates noise, which improves communication quality.

 As of 2001, the proposed diving helmet is at the prototype stage. Tests of the prototype showed the reliability and efficiency of the invention.

 The effectiveness of the diving helmet, which prevents fogging of the windows of the windows, the authors see in the speed of commissioning, simplicity of design, high reliability, non-distraction of the diver from the work and the possibility of use in normal and high ambient pressure.
