Description

Technical Field

[0001] This application belongs to the field of power generation equipment technology, and in particular relates to an air intake protection device for containerized diesel generator sets. Background Technology

[0002] On offshore platforms, diesel generator sets are typically installed inside a container to protect the equipment from the external environment. To ensure efficient combustion and heat dissipation, air inlets and outlets must be provided on the container.

[0003] However, in marine environments, containers may encounter rough seas. Huge waves can crash against the container, allowing seawater to flood in through the air intakes. This can damage internal equipment, leading to significant economic losses and safety incidents, while also accelerating the corrosion of metal components. Currently, common protective measures include installing simple rainproof louvers or wire mesh at the air intakes. Ordinary rainproof louvers are insufficient to withstand the direct impact and penetration of waves, allowing seawater to easily seep through the gaps. While simple wire mesh can block most splashes, it can be instantly covered by water during large waves, severely hindering air intake and causing generators to shut down due to insufficient airflow. It also presents drainage problems. Summary of the Invention

[0004] This application provides an air intake protection device for containerized diesel generator sets, which can solve the problems of difficulty in resisting wave impact, insufficient air intake, and poor drainage in marine environments.

[0005] In a first aspect, embodiments of this application provide an air intake protection device for a containerized diesel generator set, the containerized diesel generator set including at least two container bodies arranged side by side, each of the two container bodies having an air intake corresponding in size and position on adjacent sides, and the air intake protection device being installed between the two corresponding air intakes; The air intake protection device is a hollow cuboid structure. The left and right sides of the air intake protection device are connected to two corresponding air inlets, respectively. The top surface of the air intake protection device is closed, and the front, rear, and bottom surfaces of the air intake protection device are all waterproof ventilation components. The waterproof ventilation assembly includes a perforated plate and louvers arranged sequentially from the outside to the inside; A salt spray filter is installed at the connection between the air inlet protection device and the air inlet.

[0006] In one embodiment of the first aspect, the left and right sides of the air inlet protection device are each provided with a frame, and the frame is provided with a first mounting hole that matches the first fastener: The air intake protection device is fixedly connected to the container body through the first fastener and the first mounting hole.

[0007] In one embodiment of the first aspect, reinforcing components are embedded in the front side, rear side, top surface and bottom surface of the air inlet protection device; The reinforcing components include staggered transverse and longitudinal reinforcing ribs.

[0009] In one embodiment of the first aspect, the louvers on the bottom surface of the air inlet protection device are provided with drainage holes.

[0010] In one embodiment of the first aspect, the aperture of the mesh plate is 15 mm.

[0011] In one embodiment of the first aspect, the distance between the perforated plate and the louver is 60 mm.

[0012] In one embodiment of the first aspect, the diameter of the drain hole is 10 mm.

[0013] In one embodiment of the first aspect, an open frame is provided on the left and right sides of the air intake protection device; The inner side of the open frame is provided with a mounting slot, which is used to embed the salt spray filter; The bottom of the open frame is also provided with a second mounting hole that matches the second fastener; The air intake protection device is fixedly connected to the salt spray filter via the second fastener and the second mounting hole.

[0014] In one embodiment of the first aspect, the air intake protection device is formed by welding carbon steel. The surface of the carbon steel is coated with an anti-corrosion coating.

[0015] The beneficial effects of this utility model are: The air intake protection device can protect the air intakes of two containers simultaneously, offering high cost-effectiveness and ease of maintenance. Furthermore, the device features waterproof ventilation components on three sides, significantly expanding the air intake area. These components combine perforated panels and louvers to provide double protection against wave impact. The device's hollow interior allows seawater to drain quickly from the bottom, preventing water from covering the air intake. This ensures that the device effectively resists wave impact while rapidly draining water, guaranteeing unobstructed air intake for the diesel generator set.

[0016] A salt spray filter is detachably installed inside the air intake protection device to filter out salt spray in the air and prevent it from entering the container and causing corrosion to the machine.

[0017] The air intake protection device is made of carbon steel coated with anti-corrosion paint. Carbon steel has a certain strength, is easy to manufacture and process, and has a low cost. The anti-corrosion paint can effectively resist the corrosion of the marine environment, giving the air intake protection device a certain degree of durability.

[0022] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0024] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0025] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] This application provides an air inlet protection device for containerized diesel generator sets, which is applied to containerized diesel generator sets used for offshore wind power generation. Each diesel generator set is typically installed inside a container. On an offshore platform, there are usually multiple containerized diesel generator sets. The air inlet protection device of this application can simultaneously protect the air inlets of two containerized diesel generator sets.

[0027] like Figure 1 The diagram shows a structural schematic of installing an air intake protection device 10 on two sets of containerized diesel generator sets. By adjusting the positions of the two container bodies 20, each of the two container bodies 20 can have an air intake with a corresponding size and position on its adjacent side. The air intake protection device 10 can then be installed between these two corresponding air intakes.

[0028] See Figure 2 This is a schematic diagram of the air intake protection device 10, which is a hollow cuboid structure. The following section describes the structure facing... Figure 1 The air inlet protection device 10 is described from the perspective shown. Its left and right sides are connected to the air inlets of the two container bodies 20, respectively. The top of the air inlet protection device 10 is closed. The front, rear and bottom sides of the air inlet protection device are all waterproof ventilation components.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, the waterproof ventilation component includes a perforated plate and louvers arranged sequentially from the outside to the inside, with a certain gap between the perforated plate and the louvers to form a drainage cavity. When waves impact the air intake protection device 10, the seawater first encounters the perforated plate 11, where most of the seawater is blocked. A small portion of water droplets passes through the perforated plate 11 and enters the drainage cavity, where they are blocked by the louvers 12. Then, a small amount of seawater collects at the bottom of the inner cavity of the air intake protection device 10 and is discharged directly from the gap between the perforated plate 11 and the waterproof louvers 2 at the bottom.

[0030] Furthermore, outside air can enter the container body 20 through the gaps between the perforated plate 11 and the louvers 12. Since the three sides adopt this waterproof and ventilated structure of perforated plate 11 and louvers 12, the air intake area is greatly increased, thereby providing sufficient air for the diesel generator.

[0031] In one alternative implementation, see Figure 3 The louver 12 includes multiple interlocking louver blades 121. Specifically, the cross-sectional shape of the louver blades 121 is S-shaped. This structure can increase the blocking strength of the louver 12 and better resist the impact of sea waves.

[0032] Furthermore, a salt spray filter is installed at the connection between the air inlet protection device and the air inlet, see [link / reference]. Figure 4 This is a structural diagram of the air intake protection device 10 with a salt spray filter 30 installed, combined with... Figure 1 External air enters the interior of the air intake protection device 10 through the waterproof ventilation components on the front, rear, and bottom sides, and then enters the interior of the container body 20 from the left and right sides of the air intake protection device 10. The salt spray particles carried with the air are filtered by the salt spray filter 30. There are two salt spray filters 30, which are installed on the left and right sides of the air intake protection device 10 respectively. The salt spray filter 30 can filter out the salt spray particles carried with the air and prevent high concentrations of salt spray air from entering the container.

[0033] In one alternative embodiment, the internal structure of the salt spray filter 30 is as follows: Figure 5 As shown, the salt spray filter 30 includes a multi-layered, labyrinthine blade structure with fine guide structures on the blades. Its filtration principle is as follows: when air containing salt spray flows through the salt spray filter 30, the salt spray particles, due to their own inertia and gravity, cannot pass through the multi-layered, labyrinthine blade structure with the airflow. The intercepted salt spray particles converge at the bottom of the salt spray filter 30 along the guide structures on the blades and are discharged, while clean air continues to flow through the gaps between the blades, thus achieving the separation of salt spray and air, and achieving the filtration purpose.

[0034] Further, see Figure 2 and Figure 3 The front, rear, top and bottom surfaces of the air intake protection device 10 are all embedded with reinforcing components 13. Specifically, the reinforcing components 13 include staggered transverse reinforcing ribs and longitudinal reinforcing ribs.

[0035] In this embodiment, the reinforcing component 13 is disposed in the area between the perforated plate 11 and the louver 12. By internally welding interlaced transverse and longitudinal reinforcing ribs, the structure of the entire air intake protection device 10 can be strengthened, enabling the air intake protection device 10 to withstand the impact of sea waves.

[0036] In one optional embodiment, due to its own gravity, the seawater experiences the greatest impact force from top to bottom and the least impact force from bottom to top on the air intake protection device 10. Therefore, the top surface of the air intake protection device 10 adopts a closed structure consisting of a reinforcing component 13 and a closed protective plate. Meanwhile, the bottom surface of the air intake protection device 10 also serves a rapid drainage function, see [reference needed]. Figure 6 The bottom louvers of the air inlet protection device 10 are provided with drainage holes 122, thereby increasing the gap of the louvers 12.

[0037] Further, see Figures 2 to 6 The air inlet protection device 10 has a frame 14 on its left and right sides, and the frame 14 is located on the outside of the air inlet protection device 10. Figure 6 As shown, the frame 14 is provided with a first mounting hole 141 that matches the first fastener.

[0038] In this embodiment, the air inlet protection device 10 is fixedly connected to the container body 20 via a first fastener and a first mounting hole 141. In an optional embodiment, the first fastener may include bolts, nuts, and washers, etc.

[0039] Further, see Figure 2 , Figure 3 and Figure 6 An open frame 15 is provided on both the left and right sides of the air inlet protection device 10. The open frame 15 is located inside the air inlet protection device 10, and a mounting slot is provided on the inner side of the open frame 15 for embedding the salt spray filter 30. Figure 6 As shown, the open frame 15 is provided with a second mounting hole 151 that matches the second fastener.

[0040] In this embodiment, the air inlet protection device 10 is fixedly connected to the salt spray filter 30 via a second fastener and a second mounting hole 151. In an optional embodiment, the second fastener may also include bolts, nuts, and washers, etc., and the standards of the first and second fasteners may be the same or different.

[0041] In one optional embodiment, the air intake protection device 10 is welded from carbon steel with a surface coated with an anti-corrosion coating. Carbon steel is a relatively strong material, easy to process, and low in cost, making the air intake protection device 10 easy to produce and promote, and possessing practicality and economy. In this embodiment, by coating the surface of the carbon steel with an anti-corrosion coating, the corrosion of the air intake protection device 10 by seawater is effectively reduced, increasing the durability of the air intake protection device 10.

[0042] As an example and not a limitation, the mesh 111 of the perforated plate 11 has a diameter of 15 mm, the distance between the perforated plate 11 and the louver 12 is 60 mm, and the drainage hole 122 has a diameter of 10 mm. In actual use, these parameters ensure that the air intake protection device 10 can withstand the impact of huge waves while having sufficient ventilation and drainage effects.

[0043] Based on the above embodiments, the beneficial effects of this utility model can be obtained as follows: 1. The air intake protection device can protect the air intakes of two containers simultaneously, offering high cost-effectiveness and ease of maintenance. Furthermore, the device features waterproof ventilation components on three sides, significantly expanding the air intake area. These components combine perforated panels and louvers to provide double protection against wave impact. The device's interior is hollow, allowing seawater to drain quickly from the bottom even if it passes through, preventing water from covering the air intake. This ensures that the device effectively resists wave impact while rapidly draining water, guaranteeing unobstructed air intake for the diesel generator set.

[0044] 2. A salt spray filter is detachably installed inside the air intake protection device to filter salt spray in the air and prevent salt spray from entering the container and causing corrosion to the machine.

[0045] 3. The air intake protection device is made of carbon steel coated with anti-corrosion paint. Carbon steel has a certain strength, is easy to manufacture and process, and has a low cost. The anti-corrosion paint can effectively resist the corrosion of the marine environment, giving the air intake protection device a certain degree of durability. At the same time, the air intake protection device has reinforcing ribs embedded inside to ensure that the overall structure is more robust and stable.

[0046] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
