Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the present utility model, all the embodiments, implementations and features of the utility model may be combined with each other without contradiction or conflict. In the present utility model, conventional equipment, devices, components, etc., are either commercially available or homemade in accordance with the present disclosure. In the present utility model, some conventional operations and apparatuses, devices, components are omitted or only briefly described in order to highlight the gist of the present utility model.

Referring to fig. 1 to 2, a circular water tank manufacturing device is characterized in that a circular base 1 is formed by a circumferential array of channel steel 11, a vertical plate 2 is inserted into a groove of the channel steel 11, and a circular platform is fixed at the center of the base 1 for placing measuring tools.

In order to further ensure the roundness of the circular water tank, the circumferential interval welding of the base 1 is fixedly provided with the ring bones, so that the deformation of the base 1 or the change of the interval distance of the channel steel 11 is avoided, and the roundness of the water tank is influenced.

The channel steel 11 and the vertical plate 2 are both made of stainless steel.

Furthermore, for convenient transportation, the lifting lug 3 is welded and fixed on the channel steel 11 on the circumference trisection line of the base 1, so that the processes of lifting and transporting the base 1 are stable.

The number of the channel steel 11 is at least 6, but also can be 12, 18 or 36 according to the size of the radiation protection water tank.

The utility model is used as follows:

inserting the vertical plate into a steel groove of the channel steel, and adjusting the vertical plate to enable the upper end face of the circumferential vertical plate to be flush;

taking a water tank with each 60-degree arc as an example, fixing a part to be assembled of the water tank on a vertical plate by spot welding to form a part of water tank base, correcting the shape of the part to be assembled of the fixed water tank by taking a shape-preserving ring with an adaptive size to ensure that the outer vertical surface of the vertical plate is positioned on the virtual circumference of the water tank, fixing the shape-preserving ring on the outer vertical surface of the vertical plate by spot welding to prevent deformation caused by displacement in the welding process, and then welding a water tank body plate of the water tank; the fixing direction can be adjusted between the adjacent vertical plates in the assembly process of the parts, so that the subsequent welding is convenient.

Repeating the steps until the welding of the circular water tank is completed.
