[0026] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0027] See Figures 1 to 5 This utility model discloses a base structure for a nuclear power plant rotating gate, including an anti-slip plate 10, a reinforcing plate 20, and a reinforcing member 30. The anti-slip plate 10 has a first surface 10a and a second surface 10b. A gate body 40 is installed on the first surface 10a of the anti-slip plate 10. The gate body 40 can be a full-height gate body, and it can be welded and fixed to the first surface 10a of the anti-slip plate 10. The nuclear power plant rotating gate can be installed on this nuclear power plant rotating gate base structure and located within the space enclosed by the gate body 40.

[0028] The second surface 10b of the anti-slip plate 10 has a plurality of limiting portions 11 along its side edge to define a limiting groove on the second surface 10b of the anti-slip plate 10. The reinforcing plate 20 is installed in the limiting groove. The reinforcing plate 20 may be welded and fixed in the limiting groove. The reinforcing plate 20 has a plurality of limiting holes 21. The reinforcing member 30 connects the inner sidewall of the limiting hole 21 to the second surface 10b of the anti-slip plate 10.

[0029] The base structure of the nuclear power plant rotary gate adopts a composite structure of anti-slip plate 10, reinforcing plate 20 and reinforcement 30, which can effectively strengthen the overall structure of the nuclear power plant rotary gate to ensure that there is no shaking or instability during the use of the nuclear power plant rotary gate, improve the operating stability of the nuclear power plant rotary gate, and extend the overall service life of the nuclear power plant rotary gate.

[0030] In some embodiments, the limiting hole 21 can be multiple sets, for example, two sets arranged in parallel at intervals, each set having three limiting holes.

[0031] In some embodiments, the limiting hole 21 is a square hole, which includes square holes and rectangular holes. The reinforcing member 30 is L-shaped and includes a first connecting part 31 and a second connecting part 32 that are perpendicular to each other. The first connecting part 31 is connected to the inner sidewall of the limiting hole 21, and the second connecting part 32 is connected to the second surface 10b of the anti-slip plate 10.

[0032] In some embodiments, the first connecting portion 31 is welded and fixed to the inner wall of the limiting hole 21, and the second connecting portion 32 is welded and fixed to the second surface 10b of the anti-slip plate 10.

[0033] The first connecting part 31 of the reinforcement 30 bears shear force, effectively preventing relative displacement between the anti-slip plate 10 and the reinforcing plate 20 due to structural deformation; the second connecting part 32 of the reinforcement 30 is attached to the lower surface (second surface 10b) of the anti-slip plate 10, and through continuous welding, a tight surface contact is formed between the reinforcing plate 3 and the anti-slip plate 10, effectively eliminating assembly gaps and avoiding hollow areas.

[0034] like Figure 3 As shown, in some embodiments, the reinforcing plate 20 may be provided with a plurality of positioning holes 22, and the second surface 10b of the anti-slip plate 10 may be provided with a plurality of positioning posts 12. The two can be inserted and fixed to each other to achieve pre-fixing and limiting functions.

[0035] In some embodiments, the first surface 10a of the anti-slip plate 10 is provided with anti-slip texture, which can improve the safety of people walking.

[0036] In some embodiments, the anti-slip plate 10 may include a metal plate. Preferably, the anti-slip plate 10 may be made of a metal plate with anti-slip texture to ensure the safety of personnel when passing through a revolving gate. In this embodiment, the anti-slip plate 10 is preferably made of 316L stainless steel patterned steel plate with surface passivation and anti-corrosion treatment, thereby achieving stronger corrosion resistance, anti-slip properties, and easy cleaning and maintenance.

[0037] In some embodiments, the reinforcing plate 20 comprises a carbon steel plate. Preferably, the reinforcing plate 20 may be made of a high-strength material, such as steel or alloy material, to improve the strength and stability of the base. The reinforcing plate 20 can be designed with different thicknesses and shapes as needed to meet different strength requirements. In this embodiment, the reinforcing plate 20 is preferably made of thick carbon steel plate and is subjected to overall hot-dip galvanizing for corrosion protection. The reinforcing plate 20 is connected to the bottom of the anti-slip plate 10, and uses a high-strength carbon steel thick plate as the core load-bearing structure, providing a stable rigid support base for the anti-slip plate 10, effectively suppressing micro-deformation caused by dynamic loads, and greatly improving the uniformity of pressure distribution on the installation contact surface. This solves the failure problems that are prone to occur in traditional thin plate structures, such as local buckling, skewness of the rotating grid support base, weld cracking, and bolt loosening, providing a safety guarantee for the long-term reliable operation of the nuclear power plant rotating grid gate in complex environments.

[0038] Furthermore, the anti-slip plate 10 can serve as a surface bearing layer, and the anti-slip plate 10 is precision stamped to form a continuous wave-shaped anti-slip texture. It is understood that bolts, nuts, washers and other connecting parts can be used to fix the reinforcing plate 20 and the anti-slip plate 10 together, so that the anti-slip plate 10 and the reinforcing plate 20 form a precise fit.

[0039] In some embodiments, to improve the corrosion resistance and aesthetics of the anti-slip plate 10 and the reinforcement plate 20, surface treatment can be performed on the surfaces of the anti-slip plate 10 and the reinforcement plate 20. Surface treatment can be carried out by spraying (materials such as anti-corrosion paint, powder coating, etc.), electroplating (galvanizing, chrome plating, etc.), oxidation (methods such as anodic oxidation, applicable to materials such as aluminum alloy), passivation (pickling passivation, applicable to stainless steel materials), etc. These methods are all conventional methods and are not specifically limited here.

[0040] In some embodiments, a honeycomb core member (or defined as a honeycomb core layer) is further provided between the anti-slip plate 10 and the reinforcement plate 20. In some embodiments, the honeycomb core member includes an aluminum alloy honeycomb core member. The honeycomb core member can form a metallurgical bonding interface with the anti-slip plate 10 and the reinforcement plate 20 through vacuum brazing. It can not only cooperate with the reinforcement plate 20 to reconstruct the load transfer path, but also absorb the transient impact kinetic energy under extreme working conditions through the plastic deformation of the honeycomb core member, preventing the expansion of brittle cracks. Thus, during use, the risk of damage to the base caused by crowded or overweight situations can be effectively reduced. The honeycomb core member (or defined as a honeycomb core layer) is made of aluminum alloy honeycomb and has the characteristics of light weight and high strength.

[0041] As Figure 5 shown, in some embodiments, the gate body 40 includes a first panel 41 and a second panel 42 arranged oppositely, the gate body 40 includes a first grid plate 43 and a second grid plate 44 arranged oppositely. The connection line between the first panel 41 and the second panel 42 is the first connection line, the connection line between the first grid plate 43 and the second grid plate 44 is the second connection line, and the first connection line and the second connection line are arranged perpendicular to each other.

[0042] The nuclear power plant rotating gate base structure further includes a support member 50. The support member 50 is provided on the first surface 10a of the anti-slip plate 10, and the support member 50 connects the bottoms of the first panel 41 and the second panel 42. Understandably, the surface of the anti-slip plate 10 provides support through the support member 50, eliminating single-point dependence, thereby effectively reducing the bending stress of the surface anti-slip plate 10.

[0043] As Figure 5 shown, in some embodiments, the support member 50 can be generally in the shape of a Chinese character 'Ri', 'Jing', or 'H'. The support member 50 includes a first support body 51, a second support body 52, a third support body 53, a fourth support body 54, and a fifth support body 55. Among them, the first support body 51 and the second support body 52 are arranged in parallel at intervals. The first support body 51 is connected to the bottom of the first panel 41, and the second support body 52 is connected to the bottom of the second panel 42 to form a frame support structure, further strengthening the overall rigidity and strength of the nuclear power plant rotating gate base.

[0044] The third support 53 and the fourth support 54 are arranged parallel to each other and spaced apart. The third support 53 and the fourth support 54 are respectively connected to the first support 51 and the second support 52. The fifth support 55 is laterally connected to the third support 53 and the fourth support 54. Preferably, the support member 50 can be a metal part, such as a stainless steel part, but no specific limitation is made here.

[0045] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
