Embodiment
[0028] Such as Figure 1-4 As shown, a positive pressure ventilation device for a locomotive electrical cabinet includes a cylindrical paper filter 1, a No. 1 pressure regulating plate 2, a double-ended threaded screw 4 and a No. 2 pressure regulating plate 6. The cylindrical paper filter 1 is a cylindrical structure. The cylindrical paper filter 1 is press-fitted on the No. 2 pressure regulating plate 6 through the double-ended threaded screw 4 and the wing nut 3 arranged above the double-ended threaded screw 4. Specifically, the No. 2 pressure-regulated plate 6 The middle part is provided with a threaded hole, and the double-threaded screw rod 4 passes through the threaded hole. The No. 2 pressure regulating plate 6 is located at the air duct opening below the electrical cabinet, and the No. 2 pressure regulating plate 6 is provided with ventilation holes with the same aperture; the No. 1 pressure regulating plate 2 is fan-shaped, and its fan-shaped right angle The end is s...

The invention discloses a positive pressure ventilation device for a locomotive electric cabinet, which comprises a cylindrical paper filter, a No. The tube paper filter is press-fitted on the No. 2 pressure regulating plate through the double-ended threaded screw and the butterfly nut above the double-ended threaded screw. Ventilation holes are provided on the pressure plate; the No. 1 pressure regulating plate is fan-shaped, and its right-angled end of the fan is sleeved on the double-ended threaded screw, and the No. 1 pressure regulating plate can rotate around the double-ended threaded screw, and the fan-shaped arc The shaped end meets the inner wall of the cylindrical paper filter. The invention is simple in structure, easy and fast in installation and maintenance, light in weight, saves time and effort, and reduces labor costs; the adjustment method of air volume is more convenient, and only the No. 1 pressure regulating plate in the cylindrical filter is rotated to block / expose the air hole The percentage can; prolong the service life of electrical equipment; reduce maintenance costs.
Description
technical field [0001] The invention relates to a positive pressure ventilation device for a locomotive electrical cabinet, belonging to the technical field of ventilation of electrical components of a diesel locomotive. Background technique [0002] The main function of the electrical cabinet for diesel locomotives is to manipulate and control the normal operation of the locomotive. During operation, the electrical components in the electrical cabinet of the diesel locomotive will generate a large amount of heat. When the heat accumulates to a certain temperature, it will have a negative impact on the normal operation of the electrical components, reduce the service life, and cause serious failures in serious cases. Accidents happen. Therefore, the diesel locomotive must be ventilated and cooled during its operation, and the air supplied to the electrical cabinet must be clean, which is conducive to improving the service life of electrical components and reducing the failu...
