Description

Technical Field

[0001] This utility model belongs to the field of power cabinet technology, specifically relating to a dustproof and rainproof intermediate frequency power cabinet. Background Technology

[0002] The medium-frequency power supply cabinet is the power supply device for the medium-frequency furnace. It uses thyristor frequency converters to provide frequency conversion current to the induction heating coils and is the main equipment that provides power to the entire medium-frequency heating system. The heating furnace head cannot work independently without the medium-frequency power supply cabinet, so the medium-frequency power supply cabinet plays a very important role in the medium-frequency heating system.

[0003] Currently, heat dissipation inside intermediate frequency power supply cabinets is achieved through heat dissipation holes on the side walls or embedded dustproof heat dissipation mesh. However, after a period of use, dust accumulates in the heat dissipation holes and dustproof heat dissipation mesh, leading to blockages. Manually cleaning the blocked areas is difficult, and some dust and splashed water can also seep through the heat dissipation holes and enter the interior of the intermediate frequency power supply cabinet, posing potential circuit hazards. Therefore, a dustproof and rainproof intermediate frequency power supply cabinet is needed to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this utility model is to provide a dustproof and rainproof intermediate frequency power supply cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof and rainproof intermediate frequency power supply cabinet, comprising an intermediate frequency power supply cabinet body, a protective shell provided on one side of the intermediate frequency power supply cabinet body, a high-protection heat dissipation mechanism provided inside the protective shell, the high-protection heat dissipation mechanism comprising a heat-conducting plate, a heat-conducting bracket, a ventilation flexible duct, and a height-adjusting crossbar, the heat-conducting plate being fixed to the inner wall edge of the protective shell, the heat-conducting bracket being fixed to one side surface of the heat-conducting plate, the ventilation flexible duct being fixed to the port of one side surface of the heat-conducting plate, the height-adjusting crossbar being slidably connected above a corresponding set of ventilation flexible ducts, a tilting mechanism provided at one end of the ventilation flexible duct, the tilting mechanism comprising a lifting slide and a pull-out screw, the lifting slide being fixed to one end of the ventilation flexible duct, and the pull-out screw being fixed to the upper end of the lifting slide.

[0006] It should be noted in the solution that an insertion opening is provided on one side surface of the intermediate frequency power supply cabinet body, and the protective shell is embedded and fixed in the insertion opening of the intermediate frequency power supply cabinet body.

[0007] It is worth noting that the heat-conducting plate extends into the inner cavity of the medium-frequency power supply cabinet body, and one end of the heat-conducting bracket penetrates the protective shell.

[0008] Furthermore, it should be noted that a guide tube opening is provided on one end face of the lifting slide, and a heat dissipation vent is provided on one side surface of the protective shell, and the heat dissipation vent is connected to the guide tube opening of the lifting slide.

[0009] In a preferred embodiment, both ends of the height adjustment crossbar are fixed with height adjustment sliders, which are slidably connected in the grooves of the protective shell.

[0010] In a preferred embodiment, an adjusting screw is threaded through the internal thread of the adjusting slider at one end of the adjusting crossbar, and a rotating bearing is fixed to the inner bottom wall of the protective shell, with the adjusting screw rotatably connected to the rotating bearing of the protective shell.

[0011] In a preferred embodiment, one end of the height adjustment screw extending out of the protective shell is fixed with a height adjustment knob, and one end of the pull-out screw extends out of the protective shell.

[0012] In a preferred embodiment, the extraction screw is slidably connected inside the protective shell, and an anti-fall knob is threaded onto the surface of the extraction screw.

[0013] Compared with the prior art, the dustproof and rainproof intermediate frequency power supply cabinet provided by this utility model has at least the following beneficial effects:

[0014] By setting up a high-protection heat dissipation mechanism, the lowered horizontal frame causes the ventilation duct to sag and compress, keeping it in a U-shape. In this way, the U-shaped ventilation duct can collect intruding dust and splash water without affecting heat dissipation, thereby reducing the risk of dust and splash water entering the interior of the intermediate frequency power supply cabinet.

[0015] With its ventilation duct and tilting mechanism, the ventilation duct can be adjusted so that one end faces downwards during cleaning, allowing for the emptying of debris. After the protective shell and mounting opening are removed, water can be channeled through the connection port on the heat-conducting plate to perform further backwashing and cleaning of the ventilation duct.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4 This utility model provides a dustproof and rainproof intermediate frequency power supply cabinet, including an intermediate frequency power supply cabinet body 1. A protective shell 3 is provided on one side of the intermediate frequency power supply cabinet body 1. A high-protection heat dissipation mechanism is provided inside the protective shell 3. The high-protection heat dissipation mechanism includes a heat-conducting plate 4, a heat-conducting bracket 5, a ventilation flexible duct 6, and a height-adjusting crossbar 9. The heat-conducting plate 4 is fixed to the inner wall edge of the protective shell 3. The heat-conducting bracket 5 is fixed to one side surface of the heat-conducting plate 4. The ventilation flexible duct 6 is fixed to the port of one side surface of the heat-conducting plate 4. The height-adjusting crossbar 9 is slidably connected above a corresponding set of ventilation flexible ducts 6. A tilting mechanism is provided at one end of the ventilation flexible duct 6. The tilting mechanism includes a lifting slide 7 and a pull-out screw 14. The lifting slide 7 is fixed to one end of the ventilation flexible duct 6, and the pull-out screw 14 is fixed to the upper end of the lifting slide 7.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that an mounting opening 2 is provided on one side surface of the intermediate frequency power supply cabinet body 1, and the protective shell 3 is embedded and fixed in the mounting opening 2 of the intermediate frequency power supply cabinet body 1.

[0025] Further as Figure 3 As shown, it is worth noting that the heat-conducting plate 4 extends into the inner cavity of the medium-frequency power supply cabinet body 1, and one end of the heat-conducting bracket 5 penetrates the protective shell 3.

[0026] The solution has the following working process: Before use, turn the height adjustment screw 11 from the height adjustment knob 12. The height adjustment slider 10, which is threaded to the height adjustment screw 11, drives the height adjustment crossbar 9 to descend. The lowered height adjustment crossbar 9 causes the ventilation flexible duct 6 to sag and compress, keeping it in a U-shape. In this way, the U-shaped ventilation flexible duct 6 can collect intruding dust and splash water without affecting heat dissipation, thereby reducing the risk of dust and splash water entering the interior of the intermediate frequency power cabinet body 1. The lower end of the protective shell 3 is provided with an air inlet, while the lower part of the lifting slide 7 is provided with a drain outlet.

[0027] As can be seen from the above working process, the lowered height adjustment frame 9 causes the ventilation flexible duct 6 to sag and compress, keeping it in a U-shape. In this way, the U-shaped ventilation flexible duct 6 can collect intruding dust and splash water without affecting heat dissipation, thereby reducing the risk of dust and splash water entering the interior of the intermediate frequency power supply cabinet body 1.

[0028] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that one end of the lifting slide 7 is provided with a guide pipe port 8, and one side surface of the protective shell 3 is provided with a heat dissipation port 16. The heat dissipation port 16 is connected to the guide pipe port 8 of the lifting slide 7. During cleaning, the anti-fall knob 15 is turned upward along the pull-out screw 14 to cancel the downward restriction of the lifting slide 7. Then, the lifting slide 7 is controlled to slide down along the protective shell 3 by using the pull-out screw 14. This allows one end of the ventilation flexible pipe 6 to be kept facing downward and to be used for dumping debris. When the protective shell 3 and the mounting port 2 are removed, water can be passed through the connecting port on the heat conduction plate 4 to perform a further backwash cleaning operation on the ventilation flexible pipe 6.

[0029] Further as Figure 4 As shown, it is worth noting that both ends of the height adjustment frame 9 are fixed with height adjustment sliders 10, which are slidably connected in the grooves of the protective shell 3.

[0030] Further as Figure 1 As shown, it is worth noting that the height adjustment slider 10 at one end of the height adjustment frame 9 is internally threaded with a height adjustment screw 11, and the inner bottom wall of the protective shell 3 is fixed with a rotating bearing 13, and the height adjustment screw 11 is rotatably connected in the rotating bearing 13 of the protective shell 3.

[0031] Further as Figure 1 As shown, it is worth noting that the height adjustment knob 12 is fixed at one end of the height adjustment screw 11 that extends out of the protective shell 3, and the end of the pull-out screw 14 extends out of the protective shell 3.

[0032] Further as Figure 1As shown, it is worth noting that the pull-out screw 14 is slidably connected inside the protective shell 3, and the surface of the pull-out screw 14 is threaded with an anti-fall knob 15.

[0033] In summary: The lowered height adjustment crossbar 9 causes the ventilation flexible duct 6 to sag and compress, keeping it in a U-shape. This U-shaped ventilation flexible duct 6 can collect intruding dust and splashed water without affecting heat dissipation, thereby reducing the risk of dust and splashed water entering the interior of the intermediate frequency power cabinet body 1. During cleaning, one end of the ventilation flexible duct 6 can be adjusted to face downwards for dumping debris. After the protective shell 3 and the mounting port 2 are removed, water can be used through the connecting port on the heat conduction plate 4 to perform further backwashing and cleaning of the ventilation flexible duct 6.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
