DETAILED DESCRIPTION

[0020] The technical scheme in the utility model embodiment will be clearly and completely described below in conjunction with the drawings in the utility model embodiment, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art belong to the range of protection of the utility model.

[0021] A kind of high-low voltage distribution cabinet ventilation device, including by cabinet 1, and the opening of cabinet 1 is rotatably installed cabinet door 2, by the setting of cabinet door 2, play the role of closure;Cabinet 1 bottom corner is respectively installed with brake movable wheel, by the setting of brake movable wheel, it is convenient to move distribution cabinet, to provide convenience for staff.

[0022] First installation mouth 3 is set in the center of the lower part of cabinet 1;In detail: the inside of first installation mouth 3 is installed with suction fan 4, and suction duct 4 is installed with suction fan 5 (suction fan 5 has belonged to prior art, this application will not be described in detail), by the setting of suction fan 5, the gas in distribution cabinet can be extracted, so that the air of outside can flow to the inside of cabinet 1, to play the role of heat dissipation;It needs to be explained that: the two ends of suction duct 4 are respectively installed with protective net 12, and suction fan 5 is located between the two protective nets 12, by the setting of protective net 12, avoid staff from being hurt by mistake.

[0023] The side of cabinet 1 is provided with a plurality of second installation mouths 6, and each second installation mouth 6 can be installed into air inlet cylinder 7, by the setting of air inlet cylinder 7, the gas of outside can flow to the inside of cabinet 1, so as to ensure that the electrical elements in cabinet 1 are cooled;Air inlet cylinder 7 is provided with protective cover 8 on one side, by the setting of protective cover 8, play the role of protection, avoid larger particles from entering the inside of cabinet 1, it needs to be explained that: a plurality of openings on protective cover 8 are downwardly arranged, which can prevent rainwater from entering the inside of cabinet 1, to avoid the damage of rainwater to filter assembly 9 or electrical elements in cabinet 1.

[0024] It needs to be explained that: the outer surface of protective cover 8 is fixed with a plurality of connecting ears 10 equidistantly along the circumferential direction, one side of air inlet cylinder 7 is provided with installation groove 11 opposite to connecting ear 10, in detail: mounting hole is formed in connecting ear 10, threaded hole is formed in one side of installation groove 11, and fixed bolt (not shown in the figure) is screwed through mounting hole and threaded hole, to fix protective cover 8, prevent protective cover 8 from falling during use;Improve the stability of the control cabinet.
