Technical Field

[0001] The utility model relates to the field of power cabinets, in particular to a dustproof power cabinet. Background Art

[0002] The power cabinet is a commonly used basic power equipment. There are two types of electrical cabinets, one is the distribution cabinet, and the other is the control cabinet, which is equipped with a large number of power components. When the power cabinet is working, a large amount of heat is generated inside. Therefore, heat dissipation windows need to be opened on the side walls of the power cabinet. At present, the basic structure of the heat dissipation windows of the power cabinet is a strip-shaped shutter, that is, a group of parallel strip holes are opened on each side wall.

[0003] However, since the electrical cabinets currently on the market mainly use heat dissipation grilles and heat dissipation windows for heat dissipation, the components inside the cabinet are directly connected to the outside and dust is easily introduced. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a dustproof power cabinet to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a dustproof power cabinet, comprising a power cabinet, a partition plate is installed inside the power cabinet, an air duct is arranged between the partition plate and the power cabinet, a heat exhaust hole is opened at the upper end of the partition plate, a heat dissipation grille is opened on the outer side of the power cabinet, a placement bin is arranged at the lower end of the power cabinet on the side away from the air duct, a heat dissipation fan blade is installed in an internal array of the placement bin, an air outlet is opened above the heat dissipation fan blade corresponding to the lower surface of the power cabinet, a guide groove is opened at the lower end of the partition plate on the side close to the air duct, a slide plate is installed inside the air duct, a slider is installed on the outer side of the slide plate located inside the guide groove, and a brush head is arranged on the lower surface of the slide plate.

[0008] As a further solution of the utility model: the partition plate is fixedly connected to the power cabinet, a pull rope is installed on the wall surface of the slide plate, and a spring is connected between the rear surface of the slide plate and the power cabinet.

[0009] As a further solution of the utility model: the placement bin is fixedly connected to the power cabinet, and the air outlet is connected to the power cabinet and the placement bin.

[0010] As a further solution of the utility model: the adjusting screw rod is engaged and movably connected with the power cabinet, and the filter pad is clamped with the placement bin.

[0011] As a further solution of the utility model: the cabinet door is rotatably connected to the power cabinet via a hinge.

[0012] As a further solution of the utility model: the heat dissipation grille is connected to the power cabinet, and the heat exhaust hole is connected to the partition plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting a partition plate near the side surface inside the power cabinet, the internal electrical components can be disconnected from direct contact with the outside air. When the heat dissipation fan blades inside the placement chamber are used for blowing, the wind flowing inside the air duct can achieve the purpose of dust avoidance. By using the placement chamber to separate the heat dissipation fan, the heat accumulation in the power cabinet during heat dissipation can be reduced.

[0015] 2. Pull the pull rope at the end of the slide to control the entire slide to move inside the guide groove, so that the brush head on the lower surface of the slide cleans the dust in the air duct to the outside, thereby reducing the amount of dust accumulated in the power cabinet.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, the present embodiment provides a dustproof power cabinet, including a power cabinet 1, a partition plate 3 is installed inside the power cabinet 1, the partition plate 3 is fixedly connected to the power cabinet 1, an air duct 13 is arranged between the partition plate 3 and the power cabinet 1, a heat exhaust hole 4 is opened at the upper end of the partition plate 3, a heat dissipation grille 2 is opened on the outer side of the power cabinet 1, and a placement bin 7 is arranged at the lower end of the power cabinet 1 on the side away from the air duct 13, the placement bin 7 is fixedly connected to the power cabinet 1, and a heat dissipation fan blade 10 is installed in an array inside the placement bin 7, and the heat dissipation fan blade 10 is installed in an array inside the placement bin 7. 0 is provided with an air outlet 8 on the lower surface of the power cabinet 1, and the air outlet 8 is connected with the power cabinet 1 and the placement bin 7. The lower end of the partition plate 3 is located on the side close to the air duct 13 and is provided with a guide groove 301. A slide plate 302 is installed inside the air duct 13, and a pull rope is installed on the wall surface of the slide plate 302. A spring is connected between the rear surface of the slide plate 302 and the power cabinet 1, and a slider 303 is installed on the outer side of the slide plate 302, which is located inside the guide groove 301, and a brush head 304 is provided on the lower surface of the slide plate 302.

[0024] like Figure 2-5 As shown, in this embodiment, a filter pad 9 is installed inside the front end of the placement bin 7, the filter pad 9 is clamped with the placement bin 7, the heat dissipation grille 2 is connected with the power cabinet 1, the heat exhaust hole 4 is connected with the partition plate 3, the lower end of the air outlet 8 is located at the lower surface of the placement bin 7, and a drive motor 12 is installed, and an adjusting screw rod 11 is installed on the lower surface of the power cabinet 1, and the adjusting screw rod 11 is engaged and movably connected with the power cabinet 1, and a cabinet door 5 is provided on the front surface of the power cabinet 1, and the cabinet door 5 is rotatably connected with the power cabinet 1 through a hinge, and a sealing gasket 6 is installed on the rear surface of the cabinet door 5.

[0025] The working principle of the utility model is as follows: when in use, a new filter pad 9 is inserted into the outlet end of the placement bin 7 as a whole, and then the cabinet door 5 is closed as a whole, and the gap between the cabinet door 5 and the power cabinet 1 is sealed by the sealing pad 6. When the electrical components inside the power cabinet 1 are working, heat is generated, and the air outlet 8 is driven by the driving motor 12 to perform a blast process. The filter pad 9 at the end of the placement bin 7 intercepts and adsorbs the dust in the air, and then is sent into the inner space of the power cabinet 1 by the air outlet 8. The air then drives the heat generated by the electrical components to the upper end of the power cabinet 1, and the heat is pushed from the heat exhaust hole 4 opened on the partition plate 3 to the inside of the air duct 13, and is continuously discharged by the wind. The dust then moves downward and is finally discharged through the heat dissipation grille 2 on the outer wall of the power cabinet 1. Under the continuous action of wind, heat dissipation can be achieved while preventing dust from flowing in. When no air blowing heat dissipation is performed, when the dust falls into the air duct 13 through the heat dissipation grille 2, the partition plate 3 is set to intercept the dust to a certain extent, thereby minimizing the dust from adhering to the internal electrical components. At the same time, after a period of time, the pull rope at the end of the slide plate 302 is pulled to control the slide plate 302 to move inside the guide groove 301 as a whole using the slider 303, so that the brush head 304 on the lower surface of the slide plate 302 cleans the dust in the air duct 13 to the outside, thereby reducing the amount of dust accumulated in the power cabinet 1.
