Description

Name of the invention: (SAFETY HELMET |

[0001] (The invention relates to personal protective equipment for operators (protection of the head, face, including eyes and chin) from radioactive radiation (alpha, beta, gamma, x-ray), electromagnetic radiation, as well as the flow of elementary particles.

Technical area

[0002] It can be used as a reusable personal protective equipment for the head (including the face, including the eyes and chin) of the operator from radioactive radiation (alpha, beta, gamma, X-ray), electromagnetic radiation, as well as the flow of elementary particles.

Prior Art

[0003] A pilot's protective helmet is known (source [1]: patent RU 2010746). The helmet [1] contains a body (helmet) with a viewing window and fixed on the body, a transparent viewing shield (visor) mounted on the axis using a bracket.

[0004] A protective helmet is known (source [2]: patent RU 2238507). The helmet [2] contains a body with a viewing window made of ballistic fabric, inside of which there is a suspension system made of belts.

[0005] A protective helmet is known (source [3]: patent RU 2334938). The helmet [3] contains a body with a viewing window, bulletproof transparent glass, and a mask. Inside the mask are air filters for breathing. The body is made of three separable and hermetically connected parts: upper, front and rear parts. Bulletproof clear glass is mounted on the top of the helmet.

[0006] Known protective helmets [1;2;3], consist of a body (helmet) with a viewing window, which has a transparent screen, such as protective glass [1;3]. Helmets [1 ;2;3] do not provide full protection of the operator's face, including eyes and chin, from radioactive radiation (alpha, beta, gamma, X-ray), electromagnetic radiation, as well as the flow of elementary particles. The limited capabilities of helmets [1;2;3] to protect the operator's face do not allow the safe use of helmets [1;2;3] under the influence of radioactive radiation (alpha, beta, gamma, X-ray), electromagnetic radiation, and elementary particles.

[0007] Helmets [1;2;3] are made as part of a sphere. Helmets can have additional protection elements inside and outside the body, made of materials with different densities and degrees of protection against external influences (shock, temperature, radiation, particle flow).

[0008] A transparent screen installed in a viewing window, or in a protective shield, is made of various types of glass or polycarbonate.

[0009] The disadvantage of special glasses and polycarbonate is that they are brittle, have a high cost due to the high complexity of manufacturing. Glass and polycarbonate have a low protective ability. To provide the necessary protection, glass and polycarbonate must be of great thickness, which increases their mass, and the final mass of the helmet.

[0010] To effectively protect the eyes from radioactive radiation (alpha, beta, gamma, X-ray), electromagnetic radiation, as well as the flow of elementary particles, it will be necessary to install glass with a thickness of more than 200 millimeters, which is unacceptable from the point of view of ergonomics and safety. Since the mass of the helmet will increase sharply, which creates increased stress on the neck muscles.

[0011] The disadvantage of the helmet [1; 3] is that the transparent screen has a small thickness and cannot effectively protect the eyes and face of the operator from radioactive radiation, and from electromagnetic radiation, and from the flow of elementary particles, and from ionizing radiation. Moreover, an increase in the thickness of the transparent screen to improve the quality of protection worsens other technical characteristics of the helmet. This limits the scope of such a helmet.

[0012] The helmet [1 ;2;3] does not allow it to be used safely for the operator in conditions of radioactive contamination. Since the operator's face, eyes, chin remain open and vulnerable to the action of radioactive radiation (alpha, beta, gamma, X-ray), electromagnetic radiation, as well as the flow of elementary particles.

Brief summary of the invention

[0013] The aim of the invention is to increase the effectiveness of protecting the operator's face, including the eyes and chin, from exposure to radioactive and electromagnetic radiation, and also from the flow of elementary particles, while maintaining the mass of the helmet in an acceptable range of values.

[0014] A protective helmet, consists of a spherical body (otherwise it can be called a "helmet") with a chin rest and a viewing window, contains a face mask that closes the viewing window, the face mask is equipped with a protective element on the outside, the face mask contains a non-through observation channel equipped with periscope surveillance system.

Technical task

[0015] The technical problem is the need to protect the head of the operator, the face (including the chin and eyes) of the operator, from the effects of radioactive and electromagnetic radiation, and also from the flow of elementary particles.

The solution of the problem

[0016] The problem is solved by the fact that the protective helmet consists of a spherical body (helmet) with a chin rest and a viewing window, contains a face mask covering the viewing window, the face mask is equipped with a protective element on the outside, the face mask contains a non-through observation channel, a periscope observation system is installed in the channel.

[0017] It is assumed that the face mask is mounted on the body with the possibility of movement. The face mask is capable of being in the up position (raised up to open the viewing window) and in the down position (lowered down to close the viewing window).

[0018] It is envisaged that a periscope surveillance system is installed on the face mask in the channel.

[0019] It is provided that the periscope viewing system of the face mask is installed so that the line of sight inside the periscope goes around the contour of the protective element and goes outside the protective element so that the horizontal axes of the lens and the eyepiece of the periscope coincide and are at the same level with the eyes.

[0020] It is envisaged that the face mask is made of material (materials) that have protective properties from radioactive and electromagnetic radiation, and also from the flow of elementary particles.

[0021] It is provided that protective elements (for example, lead, polyethylene, etc.) are attached to the face mask, which have protective properties from radioactive and electromagnetic radiation, and also from the flow of elementary particles

Positive effects of the invention

[0022] The technical result is to protect the head of the operator, the face (including the eyes and chin) of the operator, from radioactive radiation, and from electromagnetic radiation, and from the flow of elementary particles, and from ionizing radiation. Brief description of the drawings

Description of Embodiments. Examples.

[0025] Protective helmet, consists of a spherical body 1 [figure 1], (helmets) with a chinrest 2 [figure 1], and a viewing window. Contains a face mask 3 [figure 1], [figure 2], covering the viewing window. Face mask 3 on the outside is equipped with a protective element 4 [figure 1], [figure 2]. The face mask 3 contains a blind observation channel 5 [figure 2]. The observation channel 5 is made in the form of a broken line, which makes it possible to provide a mechanical barrier for radioactive radiation, and electromagnetic radiation, and the flow of elementary particles, and ionizing radiation.

[0026] The face mask 3 is made without a through observation hole(s) or channel. It is assumed that the face mask is mounted on the body with the possibility of movement. The face mask is capable of being in the up position (raised up to open the viewing window) and in the down position (lowered down to close the viewing window).

[0027] In one of the possible embodiments, the body 1 is made of material (materials) that have protective properties from radioactive and electromagnetic radiation, as well as from the flow of elementary particles.

[0028] In one of the possible embodiments, the face mask 3 is made of material (materials) that have protective properties from radioactive and electromagnetic radiation, as well as from the flow of elementary particles. [0029] In one of the possible embodiments, protective elements (for example, lead, polyethylene, etc.) are attached to the face mask 3, which have protective properties from radioactive and electromagnetic radiation, as well as from the flow of elementary particles.

[0030] The face mask 3 covers the viewing window, being located between the upper part of the body 1 and the chinrest 2 [Fig.1]. From the outside, a protective element 4 is attached to the face mask 3, which protects the face and eyes of the operator from radioactive and electromagnetic radiation, as well as from the flow of elementary particles.

[0031] In one of the possible embodiments, a periscope surveillance system 5 is attached to the face mask 3 in the observation channel 5.

[0032] In one of the possible embodiments, the periscope observation system can be installed so that the line of sight goes around the contour of the protective element 4 and goes outside the protective element 4 so that the horizontal axes of the lens and the periscope eyepiece coincide and are at the same level with the eyes operator.

[0033] In one of the possible embodiments, the periscope observation system can be installed so that the line of sight goes around the contour of the face mask 3 and goes outside the face mask 3 so that the horizontal axes of the lens and the periscope eyepiece coincide and are at the same level with the eyes operator.

Industrial Applicability

[0034] The described protective helmet in all particular embodiments provides full protection of the operator's face, including the eyes and chin, from radioactive radiation (alpha, beta, gamma, x-ray), electromagnetic radiation, and also the flow of elementary particles ..

[0035] USE. The protective helmet works as follows. [0036] Before starting work, the operator puts on personal breathing protection and puts a protective helmet on his head. He puts the spherical body 1 on his head, placing his face in the viewing window, his chin opposite the chin rest 2. After checking the performance of individual means of breathing protection, the operator moves to the workplace. The operator watches the workplace through a viewing window in the body 1 of the helmet. In this case, the face mask 3 is in the upper position (raised up). Immediately before starting work in the hazardous area, the operator lowers the face mask 3 equipped with a protective element 4 to the lower position and monitors the workplace through channel 5. The observation channel 5 is made in the form of a broken line, which makes it possible to provide a mechanical barrier to radioactive radiation and electromagnetic radiation , and the flow of elementary particles, and ionizing radiation. When leaving the danger zone, the operator raises the face mask 3 to the upper position and monitors the workplace through the viewing window.

[0037] Channel 5 houses a periscope surveillance system. The face mask 3 has no through holes and therefore provides the maximum degree of protection. Inclined glasses of the periscopic observation system in channel 5 transmit and reflect the visible part of the light spectrum, but do not transmit or reflect radioactive and electromagnetic radiation, and also the flow of elementary particles. The protective element 4 does not transmit and does not reflect radioactive and electromagnetic radiation, and also the flow of elementary particles. This ensures the protection of the face (including eyes and chin) of the operator from radioactive radiation, and from electromagnetic radiation, and from the flow of elementary particles, and from ionizing radiation.

[0038] A feature of the periscope surveillance system is that the line of sight inside the periscope goes around the contour of the protective mask 3 and goes outside the protective mask 3 in such a way that the horizontal axes of the lens and the eyepiece of the periscope coincide and are at the same level with the eyes. This allows the operator to use monitoring and control devices without difficulty.

[0039] Unfavorable and hazardous to human health production factors (radioactive and electromagnetic radiation, and also the flow of elementary particles) are delayed by the protective element 4, which is attached to the face mask 3.

[0040] Thus, the use of this protective helmet will improve the efficiency of protecting the operator from the effects of radioactive and electromagnetic radiation, and also from the flow of elementary particles.
