Hydraulic mechanical heat dissipation device for railway transportation

Abstract

The invention discloses a hydraulic mechanical heat dissipation device for railway transportation, relates to the technical field of railway transportation, and solves the problem that dust is easily accumulated on the surface layer of a protective cover to form a dust net. The device specifically comprises a first oil tank and a second oil tank which are fixed to the top of a base, wherein the bottom end of the second oil tank is fixed to the top end of the first oil tank through a damping buffering mechanism; and the damping and buffering mechanism comprises four sets of telescopic legs and first springs wrapping the outer walls of the telescopic legs, and a supporting plate is fixed to the bottom end of the second oil tank through bolts. A cleaning rack is arranged, in order to reduce the wind influence of the cleaning rack on a hydraulic oil radiator, ten or more sets of exhaust holes are formed in the side wall of the cleaning rack, in order to reduce the accumulation of dust in the exhaust holes, the exhaust holes are of circular truncated cone hole structures, the small-aperture positions of the exhaust holes face inwards, hot air is exhausted through the exhaust holes after the dust is cleaned, and meanwhile, due to the inclined design, dust can be prevented from being accumulated in the holes.

Description

Technical field [0001] The present invention relates to the field of railway transportation techniques, and more particularly to a hydraulic mechanical heat dissipation apparatus for railway transportation. Background technique [0002] In the fields of mechanical, chemical, construction, etc., the use of hydraulic structures can be used as the power of equipment, and there is a movement in multiple fields, and there is a lack of hydraulic structures will make most of their daily lives. It is impossible to use, so the improvement of hydraulic structures is very necessary. The process of hydraulic devices produces a lot of heat, which can affect the use of hydraulic machines when they cannot disappear. [0003] According to the search, the Chinese patent application No. 201811460723.4 discloses a hydraulic mechanical heat dissipation device, including hydraulic machinery, a display, a semiconductor refrigerator, a protective cover, a support post, a fan, and a temperature meter, c...

AI Technical Summary

Problems solved by technology

The hydraulic mechanical heat dissipation device in the above patent has the following disadvantages: there is a protective cover on the outside of the fan, and dust is easy to accumulate on the surface of the protective cover to form a gray net, which seriously affects the heat discharge and reduces the cooling effect of the hydraulic oil radiator. The phenomenon of excessive temperature damage or even cylinder explosion occurs
