[0024] 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.

[0025] See Figures 1 to 5This utility model discloses a waterproof structure for the roof of a rotating gate pavilion in a nuclear power plant, including a housing 10. The housing 10 has a receiving groove 10a for installing electrical components, and the top of the housing 10 also has an opening. The opening is generally rectangular, and a waterproof enclosure 11 extends upward from the periphery of the opening. The waterproof enclosure 11 is generally rectangular and ring-shaped. The electrical components include core components such as the mechanism and the main control board.

[0026] The waterproof structure of the rotating gate pavilion roof of the nuclear power plant also includes a cover plate 20 for covering the opening. The cover plate 20 is generally cylindrical, with a generally rectangular cylindrical structure. The cover plate 20 may include a top wall 21 and an annular peripheral wall 22 extending from the periphery of the top wall 21. The cover plate 20 is placed over the waterproof enclosure 11 to form a first rigid waterproof barrier, so that when rainwater or other impurities fall onto the enclosure 10, they will slide off the outside of the cover plate 20 and not enter the interior of the enclosure 10, thereby improving the waterproof performance of the enclosure 10 and ensuring the operational stability and safety of electrical components.

[0027] like Figure 3 and Figure 4 As shown, in some embodiments, a support portion 12 extends outward from the upper end of the waterproof enclosure 11. The support portion 12 may be perpendicular to the upper end of the waterproof enclosure 11, and its upper surface is flat. The inner wall surface of the top wall 21 abuts against the upper surface of the support portion 12, thereby achieving a second seal and improving the waterproof and dustproof effect. In some embodiments, the support portion 12 may also be provided with a sealing groove, and a sealing ring, such as a silicone sealing ring, may be provided in the sealing groove. The inner wall surface of the top wall 21 abuts against the upper surface of the sealing ring, which can improve the sealing performance.

[0028] In some embodiments, a fixing portion 23 extends outward from the lower end of the annular peripheral wall 22. The fixing portion 23 may be vertically connected to the lower end of the annular peripheral wall 22, and the fixing portion 23 may be detachably connected to the top of the housing 10.

[0029] Preferably, the lower ends of opposite sides of the annular peripheral wall 22 have fixing portions 23 extending outward, and the fixing portions 23 are detachably connected to the top of the housing 10. Alternatively, all lower ends of the annular peripheral wall 22 have fixing portions 23 extending outward, and the fixing portions 23 are detachably connected to the top of the housing 10.

[0030] In some embodiments, the fixing part 23 is connected to the top of the housing 10 by a fastener 30. In some embodiments, the fastener 30 includes a bolt or a screw.

[0031] like Figures 2 to 5As shown, in some embodiments, drainage channels 13 are formed at the bottom of both sides of the housing 10, and drainage outlets 131 are provided at the bottom of both sides of the drainage channels 13. The waterproof structure of the nuclear power plant rotating gate pavilion roof also includes a water guide 40, which is connected to the inner wall of the top of the housing 10 and is located close to the opening. The water guide 40 has a water guide groove 41, and the projections of the support part 12 and the fixing part 23 are both located in the water guide groove 41. The two ends of the water guide groove 41 are opposite to the drainage channel 13. Preferably, the two ends of the water guide groove 41 are opposite to the drainage outlets 131 of the drainage channel 13. The top opening of the water guide groove 41 can be directly below the connection between the waterproof enclosure 11 and the cover plate 20, thereby ensuring that rainwater seeping in from the connection gap of the fastener 30 is quickly caught and preventing rainwater from entering the interior of the housing 10.

[0032] In some embodiments, the two ends of the water guide channel 41 are gradually inclined toward one side of the drainage channel 13, and the height of the middle part of the drainage channel 13 is higher than the height of the two sides of the drainage channel 13, so that rainwater and the like can flow into the drain outlet 131 after entering the drainage channel 13. The middle part of the drainage channel 13 may be provided with a waterproof horn hole or other structure.

[0033] In some embodiments, the waterproof structure of the rotating gate pavilion roof of the nuclear power plant is also provided with a sealing plug for sealing the drain outlet 131. Under normal circumstances, when there is no rain, the sealing plug can be used to seal the drain outlet 131 to prevent moisture from the air from entering the housing 10. Once water enters the housing 10, the sealing plug can be opened to drain the water, and then it can be resealed.

[0034] Understandably, liquids (such as water) or other impurities in the water guide channel 41 can flow into the drainage channel 13. In this case, a water guide pipe or similar structure is not required, simplifying the internal structure of the housing 10 and optimizing the assembly process. Understandably, the bottom of the water guide channel 41 has a water-guiding slope that gradually decreases from its center towards the drainage channel 13, thereby preventing rainwater from accumulating inside the water guide channel 41 and ensuring that rainwater can flow smoothly into the drainage channel 13. The drainage channel 13 can be a plate structure integrally formed with the housing 10, eliminating the need for additional drainage components and complex installation processes, thus improving installation efficiency and reducing process costs.

[0035] Furthermore, the bottom of the drainage trough 13 may be provided with a drainage slope, and a drainage outlet 131 is provided inside the drainage trough 13. The drainage outlet 131 may be located at the lowest point inside the drainage trough 13 and directly connected to the outside of the box body 10, so as to smoothly discharge the rainwater flowing into the drainage trough 13 from the water guide channel 41. By eliminating the drainage pipe connection structure, the number of parts is reduced, and the complex process required for drainage pipe installation is avoided. At the same time, through the drainage outlet 131 integrally formed with the drainage trough 13, dust, debris and other pollutants can be directly flushed out with the water flow, greatly reducing the probability of blockage.

[0036] Of course, in some embodiments, water guide pipes may be provided at both ends of the water guide trough 41, with one end of the water guide pipe connected to the drainage trough 13, or one end of the water guide pipe connected to the drain outlet 131.

[0037] In some embodiments, the cover plate 20 is an integral structure.

[0038] In some embodiments, the housing 10 and the cover plate 20 are both made of stainless steel. Both the housing 10 and the cover plate 20 can be made of high-strength, corrosion-resistant stainless steel, such as 316L stainless steel.

[0039] In some embodiments, the top of the enclosure 10 is further provided with a plurality of lifting lugs 50. The lifting lugs 50 may be arranged at the four opposite corners of the top of the enclosure 10 and can be used to lift the top of the rotating gate pavilion of a nuclear power plant.

[0040] Understandably, the waterproof structure of the rotating gate pavilion roof of the nuclear power plant also includes a cover plate 20 for covering the opening. The cover plate 20 is generally cylindrical, with a generally rectangular cylindrical structure. The cover plate 20 may include a top wall 21 and an annular peripheral wall 22 extending from the periphery of the top wall 21. The cover plate 20 is fitted over the waterproof enclosure 11, forming a first rigid waterproof barrier. A support portion 12 extends outward from the upper end of the waterproof enclosure 11. The support portion 12 may be perpendicular to the upper end of the waterproof enclosure 11, and its upper surface is flat. The inner wall surface of the top wall 21 abuts against the upper surface of the support portion 12, thereby achieving... The second sealing allows the water guide 40 and drainage channel 13 to directly guide the infiltrated rainwater to the outside of the housing 10 (outside the roof of the nuclear power plant's rotating gate pavilion). This ultimately constructs a multi-level protection system of "rigid barrier - secondary sealing - integrated drainage," preventing rainwater from entering the interior of the housing 10, avoiding damage to the electrical components inside the housing 10, ensuring the stable operation of the nuclear power plant's rotating gate, extending the service life of the nuclear power plant's rotating gate, reducing maintenance costs, improving waterproof reliability, drainage efficiency, and structural stability, while reducing the risk of blockage and maintenance costs.

[0041] 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.
