Description

Technical Field

[0001] This utility model relates to the field of air inlet grille technology, and in particular to an anti-splash air inlet grille for cooling towers. Background Technology

[0002] A cooling tower is a cooling device that cools by exchanging heat between water and air. The air inlet grille of a cooling tower is a mesh or grid structure installed at the air inlet of the cooling tower. Its core function is to protect the internal components of the tower, but at the same time, it must also ensure that air can flow in smoothly.

[0003] For example, the utility model patent with Chinese patent number CN202422792050.X discloses a water-splashing air inlet grille for cooling towers. The grille, composed of an inclined plate, a horizontal plate, and an inclined plate, allows water splashing inside to temporarily accumulate on the horizontal plate. The closed structure can be opened later using a closed installation structure, allowing water to fall through the through holes and be guided and recovered through the bottom inclined surface, improving utilization. The L-shaped air duct, protruding part, and air outlet form a downward airflow wall on the right side of the grille, reducing the probability of water splashing into the grille.

[0004] While the aforementioned devices can effectively prevent water from splashing outside the cooling tower, they cannot effectively block dust and other impurities outside the cooling tower. Dust or impurities can easily pass through the grille and enter the cooling tower, polluting the water inside, or accumulating directly on the top of the horizontal plate. Impurities, after flowing with the water circulation into the spray equipment, can also affect the use of the equipment and reduce its service life. Utility Model Content

[0005] This utility model discloses a splash-proof air inlet grille for cooling towers, which solves the problem of not being able to effectively block dust and other impurities outside the cooling tower.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A splash-proof air inlet grille for a cooling tower includes a mounting frame. A set of inclined plates evenly distributed from top to bottom is fixed to the inner side of the mounting frame, with the inclined plates tilted towards the side of the mounting frame away from the air inlet side. A connecting plate is hinged to the side of the inclined plate near the air inlet side of the mounting frame, and a connecting rope is fixed to the set of connecting plates. The mounting frame is provided with a winding rod for winding or unwinding the connecting rope, and a motor for driving the winding rod is provided on the mounting frame. A filter plate is fixed to the bottom of the inclined plate and is fixed to the inner wall of the mounting frame.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] As water falls through the cooling tower, it splashes, and a set of inclined plates can block the water, preventing it from splashing outside the grid. The water then flows downwards through the inclined surface at the top of the plates. When outside air passes through the filter plate, the filter plate can block dust and other impurities in the air. When it is not necessary for air to enter the cooling tower, the winding rod can be unwound from the connecting rope, making the connecting plate vertical, so that the grid can be directly sealed, further preventing dust from entering the cooling tower. At the same time, the filter plate is shielded, extending its service life and reducing the frequency of cleaning. This invention effectively prevents water from splashing outside the grid and also prevents dust and other impurities from entering the cooling tower, thus preventing dust from contaminating the water inside the cooling tower.

[0013] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 and Figure 2As shown, this utility model provides a splash-proof air inlet grille for cooling towers, including a mounting frame 1. A set of inclined plates 2, evenly distributed from top to bottom, are fixed to the inner side of the mounting frame 1. The inclined plates 2 are inclined towards the side of the mounting frame 1 away from the air inlet side. A connecting plate 3 is hinged to the side of the inclined plate 2 near the air inlet side of the mounting frame 1. A connecting rope 4 is fixed to the set of connecting plates 3. A winding rod 5 for winding or unwinding the connecting rope 4 is provided on the mounting frame 1. A motor 51 for driving the winding rod 5 is provided on the mounting frame 1. A filter plate 7, fixed to the inner wall of the mounting frame 1, is fixed to the bottom of the inclined plate 2. A fixing plate 6 is fixed above the set of connecting plates 3 on the mounting frame 1. Two oppositely distributed connecting blocks 61 are fixed on the fixing plate 6. The main body of the motor 51 is fixed to one connecting block 61, and the end of the winding rod 5 away from the motor 51 is rotatably connected to the other connecting block 61. A rotating rod 62 is rotatably connected to the fixed plate 6. A vertical plate 63 is fixed to the top of the fixed plate 6. An auxiliary rod 64, which is flush with the winding rod 5, is rotatably connected to the vertical plate 63. The rotating rod 62 and the auxiliary rod 64 are located between the winding rod 5 and the connecting rope 4, respectively, and are in contact with the connecting rope 4. After the winding rod 5 winds up or unwinds the connecting rope 4, the connecting rope 4 rubs against the rotating rod 62 and the auxiliary rod 64, causing the rotating rod 62 and the auxiliary rod 64 to rotate. When water in the cooling tower splashes as it falls, a set of inclined plates 2 can block the splashing water, preventing it from splashing outside the mounting frame 1. The water then flows downwards through the inclined surface at the top of the inclined plates 2. Meanwhile, when external air passes through the filter plate 7, the filter plate 7 can block dust and other impurities in the air. There are two connecting ropes 4, symmetrically distributed front and back, and connected to the front and back of a set of connecting plates 3 respectively. When air is not needed to enter the cooling tower, the motor 51 can be started to unwind the connecting ropes 4 using the winding rod 5. After the connecting ropes 4 move, they rub against the rotating rod 62 and the auxiliary rod 64, causing the rotating rod 62 and the auxiliary rod 64 to rotate, ensuring that the winding rod 5 can more smoothly unwind the connecting ropes 4. The connecting plate 3 is wound up to open the gap between two adjacent inclined plates 2 when it is in a horizontal position, or to close the gap when it is in a vertical position. When the connecting plate 3 is in a vertical position, it is easier to directly seal the grille, further preventing dust from entering the cooling tower. At the same time, it shields the filter plate 7, extending the service life of the filter plate 7 and reducing the number of times the filter plate 7 needs to be cleaned. When the connecting rope 4 is unwound, the connecting plate 3 can also be tilted (towards the direction away from the mounting frame 1, i.e., tilted to the left), which will block most of the gap between the two inclined plates 2. This can ensure that air can pass through the filter plate 7, and can also block dust in the air to the maximum extent, further improving the service life of the filter plate 7.

[0015] like Figure 1 and Figure 2As shown, a silicone foam 21 is fixed to the top surface of the inclined plate 2. A stop block 8 is fixed to the top of the uppermost inclined plate 2 within the mounting frame 1. A fixing block 9 with the same inclination direction as the inclined plate 2 is fixed to the bottom of the mounting frame 1. The silicone foam 21 is made of hydrophobic silicone foam (such as fluorinated or silica nano-coated): its open-cell structure absorbs energy and is hydrophobic. When water splashes onto the inclined plate 2, the silicone foam 21 comes into contact with the water, which can effectively reduce the noise generated. The stop block 8 can block the gap between the uppermost inclined plate 2 and the top of the mounting frame 1, preventing dust from entering the mounting frame 1. The fixing block 9 can effectively allow water dripping into the bottom of the mounting frame 1 to flow back into the cooling tower.

[0016] like Figure 1 As shown, the filter plate 7 has a magnet 71 embedded on its windward side, and the connecting plate 3 is made of magnetic material. The connecting plate 3 is made of steel. When the connecting plate 3 is in a vertical position, it comes into contact with the magnet 71, which attracts the connecting plate 3 to increase its stability.

[0017] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
