Description

Technical Field

[0001] The present invention relates to the field of storage tanks, and particularly to a tritiated water storage tank and its installation process.

Background Art

[0002] A tritiated water storage tank is a special container for storing water (tritiated water, HTO or T2O) containing the radioactive isotope tritium. Since tritium is radioactive, tritiated water storage tanks are generally stored in underground isolation rooms. An opening is provided at the top of the underground isolation room. One by one, tritiated water storage tanks are lowered into the underground isolation room through the opening at the top of the underground isolation room by a hoisting device, and then several workers arrange them in an orderly manner. We found in our daily work that due to the heavy weight of tritiated water storage tanks, the labor intensity of workers is greatly increased. Therefore, we are thinking about how to improve the structure of tritiated water storage tanks so that it is convenient for workers to arrange them in an orderly manner after they enter the underground isolation room.

Summary of the Invention

[0003] To solve the above problems, the purpose of the present invention is to provide a tritiated water storage tank and its installation process that can reduce the labor intensity of workers.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: a tritiated water storage tank, comprising: a tank body, a skirt is provided at the bottom of the tank body, and several mounting seats are provided above the skirt. At least three groups of jack support plate assemblies and at least three groups of tooling wheel assemblies are installed on the mounting seats. The mounting seat includes a first vertical plate and a second vertical plate welded above the skirt, and a cross plate welded above the first vertical plate and the second vertical plate. The first vertical plate, the second vertical plate and the cross plate are respectively welded to the outer wall of the tank body. The jack support plate assembly includes: a jack support plate, at least two vertical rib plates welded above the jack support plate, and a first support seat and a second support seat welded below the jack support plate. The first support seat supports on one of the adjacent two mounting seats, and the jack support plate, the first support seat and the cross plate are connected by a first fixing member. The second support seat supports on the other of the adjacent two mounting seats, and the jack support plate, the second support seat and the cross plate are connected by a second fixing member. The tooling wheel assembly is arranged below the skirt. The tooling wheel assembly includes: a mounting plate and three connecting columns welded below the mounting plate. A tooling wheel seat is welded below each connecting column, and a tooling wheel is installed in the tooling wheel seat. The mounting plate and the cross plate are connected by a third fixing member.

[0005] Preferably, a tritiated water storage tank in the present invention is further provided as: the central axis of the tooling wheel and the central axis of the connecting column do not intersect.

[0006] Preferably, a tritiated water storage tank in the present invention is further configured as follows: the first fixing member, the second fixing member, and the third fixing member are all bolts and nuts.

[0007] Preferably, a tritiated water storage tank in the present invention is further configured as follows: the gaps between the two vertical rib plates of the jack support plate assembly and the outer wall of the tank are filled with steel plates.

[0008] Preferably, a tritiated water storage tank in the present invention is further configured as follows: a semi-circular groove matching with the bolt is provided at the edge of the skirt.

[0009] Preferably, a tritiated water storage tank in the present invention is further configured as follows: the first vertical plate and the second vertical plate are arranged in parallel, and the horizontal plate is perpendicular to the first vertical plate and the second vertical plate respectively.

[0010] Preferably, a tritiated water storage tank in the present invention is further configured as follows: the two vertical rib plates are arranged in parallel, and the two vertical rib plates are perpendicular to the jack support plate respectively.

[0011] Preferably, a tritiated water storage tank in the present invention is further configured as follows: the jack support plate assembly and the tooling wheel assembly are arranged staggeredly in the circumferential direction.

[0012] To achieve the above object, the technical solution adopted by the present invention is as follows: an installation process of a tritiated water storage tank includes the following steps: A. First, the tritiated water storage tank is lifted into the underground isolation chamber through the top opening of the underground isolation chamber by a hoisting device; B. Then, through the tooling wheel assembly arranged at the bottom of the tritiated water storage tank, the worker pushes the tritiated water storage tank to the designated position; C. Then, the jack is used to lift the jack support plate from below the jack support plate to lift the entire tritiated water storage tank, and then the installation hole of the tritiated water storage tank and the civil engineering embedded hole are adjusted to be concentric, and then the tooling wheel assembly is removed; D. Finally, the entire tritiated water storage tank is lowered to the ground of the underground isolation chamber by the jack, and then the entire tritiated water storage tank is fixed to the ground by anchor bolts.

[0013] Compared with the prior art, the present invention has the following beneficial effects: by setting a detachable tooling wheel assembly, the present invention facilitates the movement of the tritium gas storage tank to the designated position by the worker, and also facilitates the removal of the tooling wheel assembly after the tritium gas storage tank is moved to the designated position. By setting the tooling wheel assembly, the installation hole of the equipment and the embedded hole on the ground can be smoothly adjusted to be concentric. In addition, by setting the jack support plate assembly, the jack can conveniently lift and lower the entire tritium gas storage tank. Since the gaps between the vertical rib plates and the outer wall of the tank are filled with steel plates, the anti-deformation ability of the jack support plate is greatly improved.

Specific Embodiment

[0019] The following further describes in detail a tritiated water storage tank and its installation process according to the present invention through specific embodiments.

[0020] Refer Figures 1 to 4 As shown, a tritiated water storage tank includes: a tank body 1, a skirt 2 is provided at the bottom of the tank body 1, and a plurality of uniformly arranged mounting seats 3 are provided above the skirt 2. At least three groups of jack support plate assemblies 4 and at least three groups of tooling wheel assemblies 5 are installed on the mounting seats 3. In this embodiment, four groups of jack support plate assemblies 4 are provided, and four groups of tooling wheel assemblies 5 are provided. The four groups of jack support plate assemblies 4 and the four groups of tooling wheel assemblies 5 are arranged staggeredly in the circumferential direction.

[0021] The mounting base 3 includes a first vertical plate 30, a second vertical plate 31 welded above the skirt 2, and a cross plate 32 welded above the first vertical plate 30 and the second vertical plate 31. The first vertical plate 30 and the second vertical plate 31 are arranged in parallel, and the cross plate 32 is perpendicular to the first vertical plate 30 and the second vertical plate 31 respectively. The first vertical plate 30, the second vertical plate 31 and the cross plate 32 are respectively welded to the outer wall of the tank body 1. The jack support plate assembly 4 includes: a jack support plate 40, at least two vertical rib plates 41 welded above the jack support plate 40, and a first support seat 42 and a second support seat 43 welded below the jack support plate 40. In this embodiment, the number of the vertical rib plates 41 is two, and the two vertical rib plates 41 are arranged in parallel and are perpendicular to the jack support plate 40 respectively. The gaps between the two vertical rib plates 41 and the outer wall of the tank body 1 are filled with steel plates. The advantage of this setting is that: during the process of the jack lifting the jack support plate 40, since the gaps between the two vertical rib plates 41 and the outer wall of the tank body 1 are filled with steel plates, its structural strength is greatly improved, preventing the jack support plate 40 from bending after being stressed. The first support seat 42 supports on one of the adjacent two mounting bases 33, and the jack support plate 40, the first support seat 42 and the cross plate 32 are connected by a first fixing member 6. The second support seat 43 supports on the other of the adjacent two mounting bases 34, and the jack support plate 40, the second support seat 43 and the cross plate 32 are connected by a second fixing member 7. In this embodiment, the first fixing member 6 and the second fixing member 7 are both bolts and nuts.

[0022] The tooling wheel assembly 5 is arranged below the skirt 2. The tooling wheel assembly 5 includes: a mounting plate 50 and three connecting columns 51 welded below the mounting plate 50. In this embodiment, the mounting plate 50 is triangularly arranged. A tooling wheel seat 52 is welded below each connecting column 51, and a tooling wheel 53 is installed in the tooling wheel seat 52. The central axis of the tooling wheel 53 does not intersect with the central axis of the connecting column 51. The reason for this setting is that: it can prevent the tooling wheel 53 from jamming and make the tooling wheel 53 move freely. The mounting plate 50 and the cross plate 32 are connected by a third fixing member 8. In this embodiment, the third fixing member 8 is bolts and nuts, and a semi-circular groove 20 matching the bolts is provided at the edge of the skirt 2.

[0023] An installation process for a tritiated water storage tank includes the following steps: A. First, use a hoisting device to lower the tritiated water storage tank into the underground isolation chamber through the top opening; B. Then, through the tooling wheel assembly arranged at the bottom of the tritiated water storage tank, workers push the tritiated water storage tank to the designated position; C. Then, use a jack to lift the jack support plate from below the jack support plate to lift the entire tritiated water storage tank, and then adjust the installation hole of the tritiated water storage tank to be concentric with the civil engineering embedded hole and then remove the tooling wheel assembly; D. Finally, use the jack to lower the entire tritiated water storage tank to the ground of the underground isolation chamber, and then fix the entire tritiated water storage tank to the ground through anchor bolts.

[0024] In summary, by setting a detachable tooling wheel assembly, the present invention facilitates the movement of the tritium gas storage tank to the designated position by workers, and also facilitates the removal of the tooling wheel assembly after the tritium gas storage tank is moved to the designated position. By setting the tooling wheel assembly, the equipment installation hole and the embedded hole on the ground can be smoothly adjusted to be concentric. In addition, by setting the jack support plate assembly, the present invention facilitates the jack to perform the lifting and lowering operations on the entire tritium gas storage tank. Since the gap between the vertical rib plate and the outer wall of the tank is filled with steel plates, the anti-deformation ability of the jack support plate is greatly improved.

[0025] The above embodiments only illustrate the principle and efficacy of the present invention and some applied embodiments, rather than limiting the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
