    The invention relates to devices for storing and transporting a capsule with a radioactive substance.
    A device for storage and transportation is known, including a storage unit with a channel passing through it, in which the radioactive substance can be safely stored when not in use, and from which the radioactive substance can be delivered to the place of use.
    Usually a radioactive substance is connected to the drive means with! a flexible cable placed in a guide tube. The guide tube is usually made of three parts of equal length, each of which can be detachably connected to the storage unit. Under the action of a manipulation tool consisting of a drum with a drive handle, the drive cable pushes the radioactive substance from the channel through the third part of the guide tube to its tip into the working position. 25
    A detachable connection is mounted on the storage unit so that when the radioactive substance is in the storage position, the drive cable can be separated from the storage unit. A part of the drive cable is locked in a detachable connection when the drive means are disconnected and removed [1].
    This device is made with a curved channel. The implementation of the curved channel in the mass of the radiation-shielding material is, however, more expensive than the implementation of the through direct channel, and the pipeline of the curved channel is subject to wear as a result of repeated pushing of the radioactive material through it.
    Closest to the proposed device is a device for storing and transporting a capsule with a radioactive substance, comprising a storage unit with a through channel, inside which a tubular element is located, and a guiding cable with a capsule placed I in it, means for studying the cable. , and a guide hose [2] connected to the storage unit by means of a connecting element.
    A disadvantage of the known devices is their inadequate safety 5 and reliability.
    The purpose of the invention is to increase the reliability of the system.
    Delivered del is achieved by the fact that in the device for storing and transporting a capsule with a radioactive substance, containing a storage unit with a through channel, inside which there is a tubular element, and a guiding cable with a capsule placed <5 in it, a manipulator associated with the cable and coupled to the storage unit via the connecting hose guide element, the connecting element is a flap with οτ -__ · θ 2 miles, mounted movably transversely to the channel at block Hrane Ia, and a hollow cylindrical member with an elastic member to move it, located within a tubular 25 member formed at this point advanced and intended to interact with a flap at the entry, it in an annular recess formed around the valve hole, the flap is provided with displacement means in the operating position , a spring element for returning it to its original position and a signaling device for visually indicating its position associated with the moving means. 35
    At the end adjacent to the shutter of the cylindrical element, an outer flange is made, ·. At the opposite end, an inner flange. The elastic element is made in the form of a spiral spring * 0 covering a cylindrical element, and is located between the outer flange and the end part of the tubular element, and a plug is connected to the capsule for interaction with the inner flange, * 5 ; laid inside the cylindrical element.
    In addition, the shutter contains means for fixing it in its original position, equipped with a movement drive. fifty
    The channel hole is provided with a sleeve located on the storage unit, and a movement drive is mounted on it.
    In FIG. 1 schematically shows a storage unit, section; in FIG. 2 - part 55 of the guide rod and the capsule with the radioactive substance; in Fig. ’3 - storage unit with a damper located on it, end view; in FIG. 4 - part of the storage unit, top view; in FIG. 5 is a sectional section of a storage unit, in FIG. 6 the same, with the shutter open; in FIG. 7 storage unit from the end side with a guide tube and a connecting cable for the drive cable, end view.
    The storage unit 1 shown in FIG. 1 and 3 - 7, made of material ^ protecting from radiation. A rectilinear channel 2 is made in the storage unit, inside of which there is a tubular element 3. At one end, the tubular element 3 is equipped with a connecting device 4, which provides the connection of the capsule 5 with the manipulation means. At the second end, the tubular element 3 is provided with a shutter 6 having an opening 7 that can coincide with the channel 2. The shutter 6 moves across the channel 2 between two extreme positions. In FIG. 1 and 4, the shutter is in the first extreme position, blocking the channel. In FIG. 6, the shutter is shown in the second extreme position when its opening 7 coincides with the channel 2.
    The capsule 5 is connected by a hinge to a guide cable connected to the manipulation means. The guide cable is made of a chain of elements 8 of the same diameter as the capsule, interconnected by means of articulated joints. The guide cable also has a section 9 of reduced diameter for locking in the connecting device 4, when the capsule with the radioactive substance must be in the storage position. Section 9 is locked in a groove (not shown) of the block 10, made with the possibility of movement in the connecting device.
    The capsule 5 is connected through an additional element 11 and a hinge to the valve control plug 12 ( having a diameter larger than the diameter of the elements 8 and 11. Tubular, the element 3 is expanded in the section 13 adjacent _ to the valve and ending at the valve. The hollow cylindrical element 14 is located inside the expanded section 13 with the possibility of sliding movement towards the damper and back.

The spiral spring 16 covers the hollow cylindrical element and interacts with the protrusion 17 of the outer flange 15 and the end, 971123 part 18 of the tubular element. The tubular element has an inner flange 19, forming a protrusion 20, with which the beveled part of the plug 12 can interact. When the radioactive substance 5 is returned to the storage position by means of manipulation means, the plug 12 leads the end of the hollow cylindrical element from the annular recess 21 against the action of the spring 16 The slider 10 ka 6 is slidably mounted in the support 22 and can be moved to the first extreme position using the spring element, blocking the channel (Fig.
    1, 3 and 4). Since the hollow cylindrical 15 element 14 does not interact with the shutter, the shutter can move and block the channel opening. In the second extreme (working) position, the shutter can be moved using 20 buttons 23, which is connected to the shutter by means of the rod 24. When the shutter is open, the button 23 you-; steps up over the housing of the storage unit (shown by the dashed line in Fig. 1) 25 1osti, connecting acting as a signal device.
    The radioactive substance 25 (figure 2) is placed in a capsule 5 connected to a guide cable using a pin 26.
    For safety purposes, the shutter is equipped with means 30 preventing its movement when the shutter blocks the channel opening, in the form of shutter fixing means 6.
    The fixing means is made in the form of a locking pin 27 having a shaft 28 (Fig. 4), which passes through the hole 29 in the shutter support 22 and can be removed from the hole with. the power of the drive 30 moving.
    In the reverse position, the locking pin can be moved using the spring 31. The drive 30 for moving the locking means is represented by a dashed line in FIG. 4, 5 and 6. This displacement drive is connected to a sleeve 32, which is a permanent part of the storage unit and is bored from the inside so as to ensure continuity of the channel.
    When the shutter is opened by moving up the button after attaching the move actuator 30 and the guide hose to the sleeve 32, the hole 7 coincides with the channel 2. The annular recess 21 around the hole in the shutter wall has an inner diameter large enough to accommodate the outer flange 15. In order to reduce sliding friction, the end of it is desirable to bevel inside. In order to avoid constant compression of the coil spring 16 by the plug 12 when the capsule 5 is placed in the storage position, the handle force of the manipulation means must be weakened after the hollow cylindrical element 14 is removed from the annular recess and the shutter is moved to the locked position.

At one end the tubular element 3 is provided with a connecting device 4, which allows the capsule 5 to communicate with the manipulation means. At the second end, the tubular element 3 is provided with a valve 6 having an opening 7, which may coincide with the channel 2. The valve 6 moves across the channel 2 between the two extreme positions. FIG. 1 and 4, the damper will be pressed in the first extreme position, blocking the channel. FIG. 6, the flap is shown in the second extreme position when its opening 7 coincides with the channel 2. The capsule 5 is connected by means of a hinge to a guide cable connected to the manipulation means. The guide cable is made of a chain of elements 8 of the same diameter as the capsule, interconnected by means of hinged joints. The guide cable also has a section 9 of reduced diameter for locking in the connecting device 4, when the capsule with the radioactive substance must be in the storage position. Plot 9 is locked in a slot (not shown) of block 10, which is adapted to move in a connecting device. Capsule 5 is connected through an additional element 11 and a hinged connection to the valve control plug 12 having a diameter greater than the diameter of elements 8 and 11.
