DETAILED DESCRIPTION

[0028] The technical solutions of the present application will be described clearly and completely below by means of specific embodiments and in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] Reference Figures 1-7 The present embodiment provides a water vapor blocking mechanism for a diesel generator air inlet grille, comprising a box body 1, wherein the inside of the box body 1 is provided with a placing cavity 11, the front end of the box body 1 is provided with an air inlet 12 communicating with the placing cavity 11, the rear end of the box body 1 is provided with an air outlet 13 communicating with the placing cavity 11, the placing cavity 11 is provided with a plurality of vertically installed air inlet grilles 2, and the air inlet grilles 2 are equally spaced in the placing cavity 11 along the horizontal direction, the windward surface of each air inlet grille 2 is provided with a baffle plate 4 for blocking water vapor, and the bottom end of the box body 1 is provided with a water pan 5 located below the placing cavity 11. By arranging the baffle plate on the windward surface of the air inlet grille, water vapor can be effectively contained and can flow downward along the baffle plate to the water pan, thereby realizing the function of blocking and collecting water vapor.

[0030] In the present embodiment, reference Figure 6 and Figure 7The baffle 4 is a metal plate, and a plurality of recesses 41 are arranged on the surface of the baffle 4. The recesses 41 form flow guide holes 42 through the baffle 4 to allow air to flow through. Specifically, the recesses 41 are square in shape, and each recess 41 is arranged in a rectangular array. More specifically, the recesses 41 are recessed on the windward surface of the air inlet grille 2. The lower part of the recess 41 is arranged at a certain inclination angle, so that the condensed water can be quickly directed downward. By arranging recesses and flow guide holes of appropriate size, water vapor can be effectively contained while ensuring air flow and maximizing water vapor interception. Preferably, the baffle is formed by stamping a stainless steel plate. The stainless steel material is corrosion-resistant, has certain strength and toughness, and has a long service life. Of course, in other embodiments, the shape of the recess 41 can also be designed as a semicircle, a semicircle, a triangle, a trapezoid, or other shapes, or the recesses 41 can be designed to be staggered.

[0031] In some specific embodiments, as shown in Figure 3 , the baffle and the windward surface of the air inlet grille have an acute angle, thereby ensuring effective interception of water vapor. Specifically, as an example, the angle can be in the range of 5° to 15°, so that water vapor can be intercepted without affecting the air flow.

[0032] In this embodiment, referring to Figure 1 , Figure 3 and Figure 4 , the inner wall of the placement cavity 11 is fixed by welding and is provided with a limiting piece 3 for positioning and installing the air inlet grille 2. The limiting piece 3 has a guide groove 31 for clamping the edge of the air inlet grille 2, and the guide groove 31 extends along the height direction of the box body 1. In this way, the air inlet grille can be inserted into the placement cavity along the guide groove to achieve quick installation.

[0033] In some specific embodiments, the edge of the baffle 4 is fixedly connected to the limiting piece 3 by welding, thereby having sufficient strength and stability to ensure that the baffle does not loosen or fall off during operation.

[0034] As an improved embodiment, referring to Figure 2 , Figure 4 and Figure 5 , the bottom of the water pan 5 is provided with a drain pipe 51. In this way, the collected water can be discharged in time through the external plastic hose. As an example, in this embodiment, the water pan 5 has two.

[0035] In addition, in other embodiments, a slope can also be designed on the bottom of the water pan 5, and a drain hole is formed at the lower end of the bottom of the water pan 5, thereby achieving timely discharge of the collected water.

[0036] In some specific embodiments, as shown in Figure 1 and Figure 3 The air inlet grating 2 is a V-shaped grating, and two baffle plates are arranged on the two sides of the V-shaped grating, one of which is arranged on the windward surface of the end of the V-shaped grating close to the air inlet, and the other is arranged on the windward surface of the end of the V-shaped grating close to the air outlet. In this way, the water vapor interception and blocking effect can be improved. As an example, in the present embodiment, the number of air inlet gratings is 10.

[0037] In other embodiments, as an improvement, as shown in Figure 8 The baffle plate 4 is fixed with a flow limiting plate 6 at the end close to the outlet. The flow limiting plate 6 is arranged in the vertical direction, and the cross-sectional shape is L-shaped. By arranging the flow limiting plate 6, water vapor can be prevented from being blown into the diesel generator under the action of air flow.

[0038] In some specific embodiments, referring to Figures 1-5 The box body 1 includes a square frame 14, two end plates 15 arranged at the left and right ends of the frame 14 respectively, and a top plate 16 arranged at the top end of the frame 14. Specifically, the frame 14 is formed by welding a plurality of stainless steel square tubes. The top plate 16 is detachably connected to the frame 14 by four screws. By opening the top plate 16, the installation or disassembly of each air inlet grating 2 can be realized.

[0039] Referring to Figure 3 During the power generation process, air flows into the generator from the air inlet 12 and flows out from the air outlet 13, during which the water vapor contained in the air is intercepted and condensed into water droplets when passing through the baffle plate 4. When the water droplets on the baffle plate 4 gradually become larger, they will automatically flow down the surface of the baffle plate 4 to the water collecting tray 5 below. The water collected in the water collecting tray 5 can be discharged in time through the drain pipe 51.
