Abstract

The invention relates to a protective technique and can be used for the maintenance and repair of protective camera equipment. The purpose of the invention is to provide the possibility of replacing exhaust filters. The device allows to carry out reloading operations for penetration, in which exhaust filters are placed, or through loading hatches, while the internal space of the device is tightly connected to the space of the chamber served, which allows using the ventilation system and deactivating the chamber during operation. The device is equipped with a box 1 and a container 2 with a lifting device 3 and a grip 4. At the upper end of the box 1 there is a flange 5 with a lid 6, and in the lower part of the box 1 there is a vertically movable seal and a flange 7. Between the flanges 5 and 7 is placed horizontally movable carriage with lodgment. The device 3 overloads the chamber equipment onto the table top where repairs are made and the protective plug 2} of the protective chamber 20 onto the carriage bed and the equipment being replaced into container 2. At the same time, the sealing flange 7 seals the joint between the device and the mortgage plate 22 of chamber 20.2 silt (L

Description

I.

This invention relates to means of remote manipulation in protective chambers and is intended for. use when working with radioactive 1-W fans.

The purpose of the invention is to provide the possibility of replacing exhaust filters.

Figure 1 shows a schematic representation of the estimated device, a general view; figure 2 - section aa in figure 1.

The device consists of a box 1 and a container 2, equipped with a lifting

a device 3 with a gripper 4; In the upper part of the box 1, a flange 5 is arranged to accommodate the container 2 and a folding flap 6. In the lower part the box 1 is equipped with a flange 7, which is connected to the drive 10 of its vertical movement by means of a gear 8 and gear 9. The opening in the flange 5 is made coaxially with the opening in the flange 7. Between the flange 5 for placing the container and the flange 7 on the rails 11 is placed with the possibility of horizontal movement of the carriage

Trunnions 16 and jacks 17 are fastened to the outer surface of the box 1, Box 1 is equipped with a folding wrench 18, the locking device of the coilner 2 is made in the form of a rotary plug 19. The device also contains a chamber 20, a protective plug

The container 2 is pulled in 8, after which the cap 19 is turned and the lid is closed. B. The container 2 is then used to transport the filter case on the saxopoHemie 1SHI to the processing position, and in its place a similar container is installed with a new filter and Same operation. The installation of the new filter is carried out in reverse order. During operation of the device, its internal space is reported

21 chambers, mortgage plate 22, exhaust air-is with serviced stone ftshtr 23, case 24 with a lid 25. The device operates as follows.

 When replacing the exhaust filter 23 of the protective chamber 20, a device using a lifting vehicle (not shown in Fig.) Is installed on the upper plane of the protective chamber 20 above the corresponding protective plug 21, which can be aligned with the sealing flange 7 years old using special markings and by means of jacks 17, the rotation of the actuator 10 is transformed by the transmission 9 and the gearbox 8 in. the accessory movement of the flange 7, which is pressed by the lower end to the mortgage plate 22 of the chamber 20, the collector 14 is connected to the decontamination system of the protective chamber, after which the lid 6 is opened and by turning the plug 19, the cavity of the container 2 connects to the cavity of box 1, the Grip 4 of the lifting device 3, lowering, engages the fungus of the protective plug 21, and the plug together with exhaust filter 23 is drawn into container 2. The cart 15 with the canister 24 pre-installed on it and the carriage 12 is brought under the opening of the flange 5, after which the grip 4 is lowered. In this case, the filter is placed in the canister 24, and the backfill plug 21 is lowered onto the bed 13, which has an opening for prop-. yekani filter The gripper 4 is disconnected from the plug mold, and the operator, using the rotary wrench 18, detaches the filter from the plug. The filter is lowered to the bottom of the canister 24, and the carriage 12 with a sealing plug is retracted from the flange opening 5, the Operator closes the canister 24 with the cover 25 and using a lifting device 3

using the ventilation system of this chamber, it is possible to provide some degree of negative pressure inside the protective chamber 1 and the container 2 o.

Discharge of radioactive substances. from the protective chamber is produced as follows.

The device is installed above the 25th stopper 21 of the containment chamber 20. With the locking device 4, it is opened and placed on the cradle 13. Then the carriage 12 is retracted to the side, the capture 4 is lowered into the protective chamber and joined to the package of radioactive substances. A lifting device is pulled into container 2, a rotary stopper closes its channel and container 2, a rotary stopper closes its channel, and container 2 is transported.

Load the protective chamber in reverse order.

At the end of the work and in all its intermediate stages, it is possible to carry out decontamination of the internal surfaces and equipment of the device using the deactivation system of the chamber being serviced.

The proposed device makes it possible to additionally replace the exhaust filters placed in the aisles of the chamber, to close the protective plug.
