Description

Technical Field

[0001] The invention relates to a shielding device, in particular to a shielding device suitable for transporting sampling samples in a nuclear power plant. Background Art

[0002] Nuclear radiation, or radioactivity as it is commonly called, exists in all substances. This is an objective fact that has existed for billions of years and is a normal phenomenon. Nuclear radiation is a stream of microscopic particles released when the nucleus of an atom changes from one structure or one energy state to another structure or another energy state. Nuclear radiation can cause ionization or excitation of matter, so it is called ionizing radiation. Ionizing radiation is divided into direct ionizing radiation and indirect ionizing radiation. Direct ionizing radiation includes charged particles such as protons. Indirect ionizing radiation includes uncharged particles such as photons and neutrons.

[0003] When sampling in a nuclear power plant, the sampled samples need to be transported, therefore, the present invention is dedicated to providing a movable shielding device. Summary of the invention

[0004] The above object of the present invention is achieved through the following technical solutions:

[0005] A shielding device suitable for transporting samples taken from a nuclear power plant comprises: a tank body is mounted on a horizontal moving device, the interior of the tank body is filled with lead; the lead-filled surface has a depression; the upper part of the tank body is open, and a cover body is provided on the tank body.

[0006] The shielding device suitable for transporting samples taken from nuclear power plants as described above, wherein the plane where the open part of the tank body is located is an inclined plane, two slide rails are arranged on the open part of the tank body, and the cover body includes: two side covers are installed on both sides of the slide rails of the tank body, and a strip opening is formed between the two side covers, and the cover body also includes an arc-shaped cover plate, a slider is installed on the arc-shaped cover plate, and the slider is slidably installed on the slide rail.

[0007] As described above, the shielding device suitable for the transportation of nuclear power plant sampling samples, wherein a stopper is installed on the slide rail, and the arc-shaped cover plate abuts against the stopper; the arc-shaped cover plate and the two side covers form a spherical cover.

[0008] The shielding device suitable for transporting samples taken from nuclear power plants as described above, wherein the horizontal moving device comprises: a plurality of universal wheels are mounted on the lower surface of the base plate, and an inverted U-shaped push handle is mounted on the upper surface of the base plate.

[0009] To sum up, due to the adoption of the above-mentioned technical scheme, the present invention places the sampling sample in a can body filled with lead inside, and is equipped with a cover body to form a closed radiation-proof space, and cooperates with the horizontal moving device and the slide rail to realize the sliding opening of the arc-shaped cover plate in the cover body. During the specific operation process, a block with a height equivalent to the arc-shaped cover plate is set, and the horizontal moving device is moved so that the block and the arc-shaped cover plate are abutted, and the horizontal moving device is continued to be moved, so that the sliding opening of the arc-shaped cover plate can be realized. Since the slide rail is inclined, after the sampling sample is placed in, the horizontal moving device is moved to make it leave the slider, and the arc-shaped cover plate automatically slides down and closes due to gravity. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 It is a cross-sectional view of the structure of the shielding device of the present invention suitable for nuclear power plant sampling and sample transportation. DETAILED DESCRIPTION

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0013] Figure 1 It is a schematic diagram of the structure of the shielding device of the present invention applicable to the transportation of nuclear power plant sampling samples. Figure 2 This is a cross-sectional view of the shielding device for nuclear power plant sampling and sample transportation according to the present invention. Figure 1 , Figure 2 A shielding device suitable for transporting samples taken from nuclear power plants, including: a tank body 2 is mounted on a horizontal moving device 1, the tank body 2 is filled with lead 9; the surface of the lead 9 has a depression; the upper part of the tank body 2 is opened, and a cover body 3 is provided on the tank body 2. After the cover body 3 is covered, a closed radiation-proof space can be formed.

[0014] Furthermore, the plane where the open part of the tank body 2 is located is an inclined plane, and two slide rails 10 are arranged on the open part of the tank body 2. The cover body 3 includes: two side covers 5 are installed on both sides of the slide rails 10 of the tank body 2, and a strip opening is formed between the two side covers 5. The cover body 3 also includes an arc-shaped cover plate 6, and a slider is installed on the arc-shaped cover plate 6, and the slider is slidably installed on the slide rail 10.

[0015] Furthermore, a stopper 8 is installed on the slide rail 10, and the arc-shaped cover plate 6 abuts against the stopper 8; the arc-shaped cover plate 6 and the two side covers 5 form a spherical cover. The stopper 8 can prevent the arc-shaped cover plate 6 from sliding off.

[0016] In the specific implementation process of the present invention, an additional block 7 can be provided, and the block can be installed as needed. The tank body 2 produces horizontal movement, and the movement direction is consistent with the sliding direction of the arc-shaped cover plate 6. The height of the block 7 is set within the height range of the sliding range of the arc-shaped cover plate 6, so that the block 7 can be operated by operating the horizontal moving device to make the arc-shaped cover plate 6 contact with each other and continue to move, thereby realizing the opening operation of the arc-shaped cover plate 6.

[0017] Furthermore, the horizontal moving device 1 includes: a plurality of universal wheels are installed on the lower surface of the base plate, and an inverted U-shaped push handle is installed on the upper surface of the base plate.

[0018] Specifically, the tank body 2 and the cover body 3 are made of metal, and lead 9 is poured inside to form a lead shielding layer. The tank body 2 and the cover body 3 constitute a closed space to achieve a shielding effect; the sampling sample 4 is placed in the cavity of the tank body 2, that is, the depression in the lead shielding layer formed by the lead pouring 9; the cover body 3 is installed on the inclined surface of the tank body 2, and the cover body 3 can slide up and down along the inclined surface; the tank body 2 is installed on a horizontally movable device, which can make the tank body 2 move horizontally, and the moving direction is consistent with the sliding direction of the cover body 3; the block 7 can hinder the movement of the cover body 3 when the tank body 2 moves, so that the cover body 3 and the tank body 2 are relatively displaced to realize the placement and removal of the sampling sample 4.

[0019] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work or software programming.
