Description

Technical Field

[0001] This utility model relates to the technical field of power cabinets, and more specifically, to an integrated high-strength IP55 protection-rated filter fan. Background Technology

[0002] With the widespread use of power equipment, outdoor power cabinets require continuous heat dissipation due to the heat generated by internal components during operation, and forced air cooling is usually used to achieve heat exchange. However, in dusty environments or rainy areas, the air inlets of traditional heat dissipation structures are mostly located on the side or top of the cabinet, and rainwater can easily be drawn directly into the cabinet with the airflow, causing a risk of short circuits in the equipment.

[0003] Based on this, the present invention provides an integrated high-strength IP55 protection level filter fan. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an integrated high-strength IP55 protection-rated filter fan, which reduces the risk of direct rainwater intake. Even if a small amount of rainwater or water vapor breaks through the protective frame and enters the air guide cover, the inclined V-shaped filter plate can effectively block most of the water droplets. The water droplets hit the inclined V-shaped surface and are more likely to condense and roll off, making it difficult for them to enter the cabinet through the filter holes.

[0005] The integrated high-strength IP55 protection-rated filter fan provided by this utility model adopts the following technical solution:

[0006] An integrated high-strength IP55 protection-rated filter fan includes an air guide cover mounted on a power cabinet; a fan mounted on the side of the air guide cover and arranged inside the power cabinet; a filter plate mounted between the fan and the air guide cover; and a protective frame detachably mounted at the bottom of the air guide cover.

[0007] Preferably, the filter holes on the filter plate are arranged in a V-shape.

[0008] Preferably, the bevel of the filter pore is inclined.

[0009] Preferably, the openwork area of ​​the protective frame is provided with mesh.

[0010] Preferably, the air guide shroud has a threaded rod rotatably mounted inside, and a movable plate is slidably mounted inside the air guide shroud via a slide rod. The movable plate is threadedly connected to the threaded rod. An inverted U-shaped frame is mounted at the bottom of the movable plate. A cleaning roller is rotatably mounted inside the inverted U-shaped frame. A driving component for driving the threaded rod to rotate is mounted inside the air guide shroud.

[0011] Preferably, a pair of spring telescopic rods are provided on the top of the moving plate, and the inverted U-shaped frame is fixedly arranged between the output ends of the two spring telescopic rods.

[0012] In summary, this utility model has the following beneficial technical effects:

[0013] When the power cabinet is cooling down, a fan draws outside air through the protective frame into the air guide hood, and then discharges it into the power cabinet through a filter plate, creating air circulation. By placing the protective frame at the bottom of the air guide hood, it can be used even in rainy weather, reducing the amount of rainwater entering the hood. A filter plate is installed between the fan and the air guide hood to block rainwater or dust from entering. The filter plate's perforations are V-shaped with an inclined surface, facilitating the falling off of adhering rainwater or dust. This structural design prevents vertically falling rainwater from being carried into the air guide hood by the airflow due to gravity, reducing the risk of direct rainwater inhalation. Even if a small amount of rainwater or moisture manages to penetrate the protective frame and enter the air guide hood, the inclined V-shaped filter plate effectively blocks most of the droplets. The droplets, impacting the inclined V-shaped surface, are more likely to condense and roll off, making it difficult for them to pass through the filter perforations and enter the cabinet.

[0014] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0023] The following is in conjunction with the appendix Figures 1 to 7 The present invention will be described in further detail below.

[0024] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown are exaggerated or reduced in size; all dimensions are merely illustrative and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0025] Example 1

[0026] This utility model discloses an integrated high-strength IP55 protection-rated filter fan. (See reference...) Figures 1 to 5 The integrated high-strength IP55 protection level filter fan includes an air guide cover 2, a fan 3, a filter plate 4 and a protective frame 5 installed on the power cabinet 1; the fan 3 is installed on the side of the air guide cover 2 and is arranged inside the power cabinet 1; the filter plate 4 is installed between the fan 3 and the air guide cover 2; the protective frame 5 is detachably installed at the bottom of the air guide cover 2.

[0027] like Figure 5 As shown, the filter holes on filter plate 4 are arranged in a V-shape.

[0028] like Figure 5 As shown, the bevel of the filter pores is set at an angle.

[0029] Specifically, when the power cabinet 1 is dissipating heat, the fan 3 operates to draw outside air into the air guide hood 2 through the protective frame 5, and then discharges it into the power cabinet 1 through the filter plate 4, thus creating air circulation. By placing the protective frame 5 at the bottom of the air guide hood 2, it can be used even in rainy weather, and the amount of rainwater entering the air guide hood 2 can be reduced. At the same time, the filter plate 4 is set between the fan 3 and the air guide hood 2, so that when rainwater or dust enters the air guide hood 2, the filter plate 4 can block it. The filter holes of the filter plate 4 are set in a V-shape, and the slope is inclined, which facilitates the falling off of attached rainwater or dust.

[0030] With this structural design, rainwater falling vertically is less likely to be carried into the air guide hood 2 by the airflow drawn in from the bottom due to gravity, reducing the risk of direct rainwater inhalation. Even if a small amount of rainwater or water vapor breaks through the protective frame 5 and enters the air guide hood 2, the inclined V-shaped filter plate can effectively block most of the water droplets. The water droplets hit the inclined V-shaped surface and are more likely to condense and roll off, making it difficult for them to enter the cabinet through the filter holes.

[0031] Example 2

[0032] This embodiment is a further optimization based on the first embodiment described above. The parts that are the same as those in the aforementioned technical solution will not be repeated here. Figure 6 As shown, in order to better realize this utility model, the following arrangement is adopted: in this embodiment, the hollow area of ​​the protective frame 5 is provided with a mesh 6.

[0033] By setting up the mesh screen 6, external flying insects and animals can be prevented from entering the air guide 2 through the protective frame 5.

[0034] like Figure 6 and Figure 7 As shown, a threaded rod 7 is rotatably arranged inside the air guide shroud 2, and a movable plate 8 is slidably arranged inside the air guide shroud 2 via a slide rod. The movable plate 8 is threadedly connected to the threaded rod 7. An inverted U-shaped frame 9 is arranged at the bottom of the movable plate 8, and a cleaning roller 10 is rotatably arranged inside the inverted U-shaped frame 9. A driving component for driving the threaded rod 7 to rotate is arranged inside the air guide shroud 2.

[0035] Specifically, the driving component includes a driven gear 12 mounted on the threaded rod 7, a motor 13 mounted inside the air guide shroud 2, and a driving gear 14 mounted at the output end of the motor 13. The driving gear 14 meshes with the driven gear 12. The motor 13 is controlled by a PLC controller and can drive the threaded rod 7 to rotate periodically in both directions.

[0036] Specifically, the motor 13 drives the drive gear 14 to rotate, which in turn causes the driven gear 12 to rotate, thereby causing the threaded rod 7 to rotate. The rotation of the threaded rod 7 causes the moving plate 8 to move, which in turn drives the cleaning roller 10 to rotate on the surface of the mesh 6 to clean the impurities attached to the mesh 6.

[0037] The side end of the threaded rod 7 is arranged outside the air guide shroud 2, and the side end of the threaded rod 7 is provided with a rotating groove. The threaded rod 7 can also be rotated by inserting a tool (screwdriver) into the rotating groove to complete the movement of the cleaning roller 10.

[0038] like Figure 6 As shown, a pair of spring telescopic rods 11 are provided on the top of the moving plate 8, and the inverted U-shaped frame 9 is fixedly installed between the output ends of the two spring telescopic rods 11.

[0039] Specifically, by setting the spring telescopic rod 11, it can be ensured that the side of the cleaning roller 10 is in contact with the side of the mesh 6.
