RU53112U1 - INSULATING SUIT - Google Patents

Abstract

The insulating suit includes a jumpsuit with which a hood with a porthole, gloves and boot covers are connected. The overalls have a compartment for the breathing apparatus, the pressure gauge of which is brought into the porthole area, and is made with the possibility of free fitting to ensure the release of the arm from the sleeve with the glove. In the chest part of the overalls, a longitudinal tightening system is made from the wrong side to ensure the suit's flexibility. Each glove is attached to the sleeve by means of a ring located inside the glove in the wrist area, on top of which, after inserting the glove into the sleeve turned inside out, and also after the glove cuff is turned off, bandages are fixed.

The technical result consists in increasing the internal free space of the spacesuit, which allows the use of undersuit space for monitoring the pressure gauge and wiping the porthole glass during fogging, having previously released the arm from the sleeve with the signet, in increasing the flexibility of the spacesuit, as well as in increasing the strength and tightness of the connection of gloves with sleeves spacesuit.

Description

The proposed solution relates to personal protective equipment, namely, protective clothing of an insulating type, designed, in particular, for employees of fire and emergency rescue services at chemical, oil, nuclear and energy industries and other similar objects.

From published application RU No. 94036349, a protective suit is known comprising a soft hermetic shell in the form of overalls with a space-type helmet hermetically connected to it, shoes and mittens and a power flange located on the back and forming a hatch for entering the suit having a hollow cover for placement in of the operator’s life support system with a reciprocal power flange containing a seal for tight connection of the hatch with the cover, the body of the life support system is equipped with shoulder and waist belts for fixing on and the operator’s body and is rigidly connected to the power flange of the cover to ensure the weight distribution of the suit on the operator’s body. This decision was made as the closest analogue.

The disadvantages of the known technical solution is the lack of ease of use of the suit, which is explained, in particular, by the complication of the pneumatic system of the breathing apparatus to allow air pressure in the cylinder to be controlled, as well as by a change in the viewing angle through the porthole when the user is tilted, which is explained by the tendency of structures with soft shells under pressure, to "float", which makes it difficult to work in such a spacesuit. Also, in the known design, the problem of sealing the glove joints with the overalls sleeves is not sufficiently technologically solved.

A common drawback of the well-known spacesuits is the insufficiently comfortable working conditions caused by the inevitable fogging of the inside window glass during operation. All known measures to eliminate this drawback, in particular, the use of anti-fogging

coatings or glass blowing are either not effective enough for a short time, or significantly complicate the design of the spacesuit systems, or lead to a noticeable consumption of the respiratory mixture in the balloon, thereby reducing the time it takes to stay in extreme conditions. As studies have shown, the most effective method of eliminating fogging of the glass is to wipe the latter by the user himself. However, such a measure requires the provision of the possibility of sufficiently free manipulations (movements) of the user's hand inside the suit.

The technical result, towards which the proposed technical solution is directed, is to increase the internal free space of the spacesuit to an extent that allows the use of undersuit space for manipulating the hand while monitoring the pressure gauge and wiping the window during fogging by first releasing the hand from the sleeve with the signet, to ensure constancy viewing angle through a spacesuit porthole by fixing the position of the hood, which does not change its position (“Does not pop up”) when tilting the user's body forward, as well as in increasing the strength and tightness of the connection of gloves with the sleeves of the suit. At the same time, the increase in the internal free space of the spacesuit is limited by ensuring the minimum necessary movements of the user's hands when wiping the glass of the porthole and controlling the pressure on the manometer.

The specified technical result is achieved in the proposed insulating suit, which includes a jumpsuit with which a hood with a porthole, gloves and shoe covers are hermetically connected, the jumpsuit has a compartment for a breathing apparatus, made in its shoulder part freely adjacent to the user's body, allowing the latter to be released sleeves with a glove for the necessary manipulations when wiping the window glass when fogging and / or to access the manometer of the breathing apparatus for monitoring the air pressure in the cylinder and has a longitudinal tightening system designed in the chest part of the overalls from its wrong side, intended for

fixing the hood and ensuring a constant viewing angle of the user through the porthole when tilting the user's body.

The signs characterizing the execution of the overalls as freely fitting as well as the performance of the longitudinal tightening system are interconnected to achieve the indicated technical result, since a looser fitting inevitably makes the overalls less manageable, allowing for spontaneous movements of the pressurized tight overalls (“floating” of the hood when the user tilts). To limit these phenomena, the proposed tightening system is used.

Preferably, the dimensions of the overalls are selected from the condition of ensuring such a minimum necessary degree of free fit of the overalls, which allows the user to relatively easily release his hand for wiping the glass of the porthole and bringing the manometer of the breathing apparatus into the viewing area of the porthole for independent control of the pressure in the cylinder of the breathing apparatus.

The signs of the dependent claims are aimed at enhancing the technical result, and also provide additional benefits.

The specified longitudinal tightening system mainly consists of belt loops glued to the overalls, straps, frames and adjusting buckles, while the belt loop or strap with one end attached to the hood.

It is advisable if each glove is attached to the sleeve by means of a ring threaded into the glove in the wrist area and secured with bandages between which sealant is poured. In this case, after inserting the glove into the sleeve turned inside out and after turning the cuff, the gloves are fixed with bandages.

The porthole consists of glass glued to the front of the hood, with the edge of the glass inside the overalls secured with tape.

A sealant is preferably applied to the edges of the hood window cut out under the glass.

The mentioned ring for attaching gloves can be made of plastic, and the bandages can be made of kapron threads.

A sealant is preferably poured between said bandages.

The insulating spacesuit is made of a thermally aggressive polymer material that prevents the penetration of water, surfactants, and aggressive media into the undersuit space.

The spacesuit is made with a set-in hood 7-9 and is equipped with a tight zipper 12, which is laid on the right front half 1.3 and on the side of the hood. The front part of the hood has a panoramic sight glass 13 porthole. From the inside, the hood dome is assembled on a screed, providing an individual fit and a constant required view through the suit's porthole. On the back is a compartment 10 for the breathing apparatus. The sleeves have a tight connection with rubber gloves 14, and the bottom of the trousers is a tight connection with rubber boots 15. The tight connection of gloves 14 and boots 15 is achieved through the use of a system of rings 23 (plastic or metal), rubber o-rings 24 and bandages 25, which gives the ability to replace one arm and leg protector with another. In particular, each glove is attached to the sleeve by placing inside the glove 14 in the wrist area of the ring 23, on top of which, after inserting the glove 14 into the sleeve turned inside out, two braces 25 are fixed, and then also two braces 25 are fixed after the glove cuff is turned away. this between the specified bandages pour sealant. After that, the sleeve is turned on the front side together with the fixed glove 14.

Inside the spacesuit, namely in the chest of the overalls, on the wrong side, a longitudinal tightening system is made to ensure stable

the position of the porthole, which consists of belt loops 16 glued to the overalls, straps 17 and 18, frames 19 and adjusting buckles 20.

On the back of the hood are located a cover 11 of the overpressure relief valve. All connecting thread seams of the spacesuit are glued from the inside with tape and covered with a heat-resistant sealant.

Use the suit as follows.

First, you must unfasten the tight zipper 12 completely and straighten the adjustment belts. After putting on the inner overalls, it is necessary to take the spacesuit by the edges of the zipper 12 at the waist and insert the legs into the boots 15 of the insulating spacesuit. Next, you should adjust the straps of the spacesuit according to the figure. In this case, check the correct fit by tilting back and forth. Then you need to put on the breathing apparatus, adjusting the position of the cylinders on the back, put on the mask, adjusting its puffs, and then connect the mask to the cylinder of the breathing apparatus. Put on a hood, head protection (a hood with a helmet or a full-time helmet of a fireman) and textile gloves, after which, with the help of an assistant, lift the suit up and insert your left hand into the suit’s sleeve, while straightening the left glove. Then, lifting up the spacesuit, straighten the compartment on the bottle and put the hood of the 7-9 spacesuit over the head. Insert the right hand into the sleeve and straighten the glove 14. Raise both hands up and to the sides. Then pass a belt with a frame 18, 19 under the waist belt of the breathing apparatus and secure it with the Velcro fastener. The assistant, holding the lower end of the zipper of the 12 spacesuit with his left hand, fastens it to 1/2 ... 3/4 of its length with the right hand. Then you need to intercept and fasten the fastener to the end. Re-raise your arms up and to the side, do squats and bends, after which the spacesuit is evenly distributed over the entire figure of a person. If necessary, you need to adjust the position of the porthole 13 and the compartment for cylinders 10. In working condition, the suit should be slightly inflated, i.e. there must be excess pressure inside the suit. In this case, make sure that there is a possibility

hand manipulation i.e. bringing the manometer into the porthole zone and releasing the arm from the spacesuit sleeves to access the porthole glass.

After completion of the work, the spacesuit is removed. When leaving the danger zone, it is first necessary to degass (or neutralize) the spacesuit by dousing with water or a specially designed solution. The assistant unzips 12 insulating spacesuit. Holding the ends of the finger parts of the right glove 14, the assistant helps to free the right hand, removes the hood 7-9 and the compartment 10 for the cylinders of the breathing apparatus, while slightly leaning forward. Next, you need to straighten and the insulating spacesuit will fall down to the regulating loop of the spacesuit. Then the inner hood and mask of the breathing apparatus are removed from the head, the breathing apparatus is removed, the zipper on the inner jumpsuit is unfastened and the arms and legs are released.

In case of emergency, the spacesuit can be independently opened for emergency release of air access to the respiratory system of the user. To do this, it is necessary to press the hood over the helmet with the left hand over the head from above. Raise your right hand and grab the holder of the zipper fastener and hold the hood firmly with your left hand, with your right hand start gently lowering the fastener to the middle of the zipper. With the left hand, holding the finger ends of the right glove, free the right hand from the sleeve of the spacesuit. Then, with your free right hand, unfasten the inner hood and, at the same time, leaning forward, grab the mask of the breathing apparatus and tear the mask off by moving your hand down, forward and up, as a result of which the head will be freed from the mask and hoods.

Thus, the user has the opportunity to both monitor the manometer (without complicating the pneumatic system of the breathing apparatus) and the ability to wipe the glass of the window as necessary (without additional expenditure of the supply of the respiratory mixture and without the use of special tools).
