[0002] Extracting krypton and xenon from liquid oxygen is an industrial process used to separate and extract the rare gases krypton and xenon from liquid oxygen. The extracted gases need to be stored in a storage device. Existing gas storage devices generally achieve the purpose of gas storage by filling the gas into a tank and closing the valve. However, the valve handwheel on the existing gas storage device is generally directly exposed to the outside, making it easy for people to accidentally touch the valve handwheel, causing the valve to open, resulting in gas leakage. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the present invention provides a storage device for extracting krypton-xenon gas from liquid oxygen, which solves the problem that the valve handwheel on the existing gas storage device is generally directly exposed to the outside, which makes it easy for people to accidentally touch the valve handwheel, causing the valve to open, thereby causing gas leakage.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a storage device for extracting krypton and xenon gas from liquid oxygen, comprising a tank body, a circular frame fixedly connected to the top of the tank body, a cover plate hinged on the circular frame, an L-shaped plate fixedly connected to the cover plate, a limiting hole being provided on the L-shaped plate, a valve assembly being provided on the tank body, a connecting pipe fixedly connected to the tank body, the connecting pipe being fixed to the circular frame, the connecting pipe being connected to the tank body, a box body fixedly connected to the circular frame, two telescopic rods fixedly connected to the inside of the box body, one end of the two telescopic rods fixedly connected to a movable plate, a limiting block fixedly connected to the movable plate, and a spring being sleeved on the telescopic rod.

[0005] As a further solution of the present invention: the limit block is designed as an inclined surface, and the position of the limit block corresponds to the position of the limit hole.

[0006] As a further solution of the present invention: one end of the spring is fixedly connected to the movable plate, and the other end of the spring is fixedly connected to the box body.

[0007] As a further solution of the present invention: a fixing plate is fixedly connected to the bottom of the tank body, and a handle is fixedly connected to the tank body.

[0008] As a further solution of the present invention: a wheel is rotatably connected to the fixing plate, and a screw is threadedly connected to the fixing plate.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The storage device for extracting krypton and xenon gas from liquid oxygen is provided with a spring, a movable plate, a circular plate, a limit block, a limit hole, a cover plate and a circular frame. When the valve assembly needs to be used, the circular plate is pressed to drive the movable plate and the limit block to move, so that the limit block is separated from the limit hole, and the fixed state of the L-shaped plate and the cover plate can be released, and the cover plate can be opened. At this time, the valve assembly is opened, and the krypton and xenon gas extracted from liquid oxygen is filled into the tank through the connecting pipe to complete the storage work. The valve assembly is closed and the cover plate is rotated closed at the same time. When the L-shaped plate contacts the inclined surface on the limit block, the L-shaped plate The limit block will be pushed so that the limit block and the movable plate are away from the L-shaped plate. When the limit hole moves to the limit block, the limit block loses the support of the L-shaped plate, causing the spring to reset and push the movable plate and the limit block to move, so that the limit block is inserted into the limit hole, and the L-shaped plate and the cover plate can be fixed. The device can quickly open the cover plate, making it easier for people to use the valve assembly. At the same time, by fixing the cover plate on the round frame, the valve assembly is fully protected by the cover plate and the round frame to prevent people from accidentally touching the valve handwheel on the valve assembly and causing gas leakage in the tank.

[0012] 2. The storage device for extracting krypton and xenon gas from liquid oxygen is provided with wheels, screws, handles, and fixing blocks. When the device needs to be moved, the screws are first loosened to release the fixed state of the wheels. At this time, the handles can be pulled to move the device. When the device is moved to the designated location, the screws are tightened to fix the wheels, and the device is placed on the ground with the support of the fixing blocks and wheels. The wheels are provided to facilitate the transfer of the device. After being moved to the designated location, the wheels are fixed by the screws to improve the stability of the device. The fixing blocks are used to raise and support the fixing plates, thereby preventing the device from tilting or even tipping over when placed. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, the utility model provides a technical solution: a storage device for extracting krypton and xenon gas from liquid oxygen, comprising a tank body 1, a round frame 4 fixedly connected to the top of the tank body 1, a cover plate 5 hinged on the round frame 4, an L-shaped plate 7 fixedly connected to the cover plate 5, a limiting hole 8 is provided on the L-shaped plate 7, a valve assembly 9 is provided on the tank body 1, a fixing plate 2 is fixedly connected to the bottom of the tank body 1, and a handle 3 is fixedly connected to the tank body 1. Since the handle 3 is provided, the handle 3 provides a gripping point, which makes it easy for people to grip the handle 3 to move the device, thereby improving the convenience of operation.

[0020] A connecting pipe 11 is fixedly connected to the tank body 1, and the connecting pipe 11 is fixed to the round frame 4. The connecting pipe 11 is communicated with the tank body 1, and a box body 10 is fixedly connected to the round frame 4. Because of the box body 10, when the movable plate 16 moves, the box body 10 can limit the movable plate 16, thereby improving the stability of the movement of the movable plate 16. A wheel 12 is rotatably connected to the fixed plate 2, and a screw 14 is threadedly connected to the fixed plate 2.

[0021] Two telescopic rods 18 are fixedly connected to the inside of the box body 10. Because of the telescopic rods 18, the telescopic rods 18 can prevent the spring 19 from excessively bending when compressed, thereby ensuring the normal use of the spring 19. One end of the two telescopic rods 18 is fixedly connected to the movable plate 16. Because of the T-shaped column 6, the cover 5 can be easily opened by pinching the T-shaped column 6, thereby reducing the difficulty of operation. The limiting block 15 is fixedly connected to the movable plate 16. The limiting block 15 is designed as an inclined surface. Because the limiting block 15 is designed as an inclined surface, it is convenient for the L-shaped plate 7 to push the limiting block 15 away, so that subsequent operations can be carried out smoothly. The limit block 15 corresponds to the position of the limiting hole 8.

[0022] A spring 19 is sleeved on the telescopic rod 18, one end of the spring 19 is fixedly connected to the movable plate 16, and the other end of the spring 19 is fixedly connected to the box body 10, the bottom of the fixed plate 2 is fixedly connected to the fixed block 13, the top of the cover plate 5 is fixedly connected to the T-shaped column 6, and the movable plate 16 is fixedly connected to the circular plate 17.

[0023] The working principle of this utility model is:

[0024] When the valve assembly 9 needs to be used, the circular plate 17 is pressed to drive the movable plate 16 and the limit block 15 to move, so that the limit block 15 is separated from the inside of the limit hole 8, and the fixed state of the L-shaped plate 7 and the cover plate 5 can be released, and the cover plate 5 can be opened. At this time, the valve assembly 9 is opened, and the krypton-xenon gas extracted from liquid oxygen is filled into the tank body 1 through the connecting pipe 11, completing the storage work, and the valve assembly 9 is closed and the cover plate 5 is rotated to close. When the L-shaped plate 7 contacts the inclined surface on the limit block 15, the L-shaped plate 7 will push the limit block 15, so that the limit block 15 and the movable plate 16 are away from the L-shaped plate 7. When the limit hole 8 moves to the limit block 15, the limit block 15 loses the support effect of the L-shaped plate 7, causing the spring 19 to reset and push the movable plate 16 and the limit block 15 to move, so that the limit block 15 is inserted into the inside of the limit hole 8, and the L-shaped plate 7 and the cover plate 5 can be fixed;

[0025] When the device needs to be moved, the screw 14 is first loosened to release the fixed state of the wheel 12. At this time, the handle 3 can be pulled to move the device. When the device is moved to the designated position, the screw 14 is tightened to fix the wheel 12, and the device is placed on the ground with the support of the fixing block 13 and the wheel 12.
