Abstract
The utility model discloses a roof inflow rainwater collecting drainage groove of an electric locomotive. The roof inflow rainwater collecting drainage groove effectively solves the problems that because air is absorbed in an electrical machine room through air passage openings of large-power electric appliances and air can not be smoothly supplemented between the electrical machines through filters, negative air pressure is formed in the electrical machine room, and rainwater flows into the edge of a roof of the electrical machine room and flows everywhere. As is shown in 1, the drainage groove is installed in the roof of the electrical machine room and a passage opening, where rainwater flows in, of a locomotive top beam. Rainwater flowing or dropping through the face of the roof, the face of the roof beam and the face of a roof rib plate is collected and drained, accordingly the phenomenon that because the rainwater flows everywhere in the electrical machine room, circuit and electric appliance grounding or short circuit is caused, and accidents caused by poor running safety of the locomotive is avoided.
Description
Technical field
The roof that the present utility model relates between electric locomotive electric apparatus enters rain collection eduction gear, for, adopt and concentrate in ventilated type electric locomotive.
Background technology
At present, electric locomotive high-power electric appliance adopts ventilation cooling, and most of electric locomotive air channel import is arranged on the locomotive shell between electric apparatus, and the benefit wind between electric apparatus is supplemented through the filter being arranged on locomotive shell by car outer air.After the filter filtered air dust foreign material of installing due to locomotive shell, stop up air channel, strengthened gradually windage, cause that to mend wind not smooth, compare with ambient atmosphere between electric apparatus, the negative pressure that formation one is larger.And the problem of bringing is, due to the existence of negative pressure, between rainy day electric apparatus, top locomotive header very easily flows to rainwater, and rainwater drips or flows on electrical equipment and causes electrical apparatus insulation short circuit accident, also affects traffic safety when serious.To this, for addressing this problem, locomotive shop adopts increases roof rail tank height, but the slightly larger still water inlet of rain; As user's locomotive depot, adopt in roof rail groove and install rubber weather strip additional, above top cover is pressed in, the entering of blocking-up rainwater.Locomotive, in operational process, causes vibration and the impact of top cover to rubber weather strip in roof rail groove, and solar ulatraviolet radiation, very easily makes rubber weather strip weight break and aging cracking in addition, still causes into water.To this, locomotive depot takes further measures, and at top cover and roof rail intersection, adopts polyurethane sealant to carry out shutoff, too due to vibration and the impact of locomotive header, colloid embrittlement occurs and loses water-proff packing effect.
Summary of the invention
In order to solve the problem that between rainy day electric apparatus, water inlet brings, the utility model adopt to become and to block up as dredging, and provides one to be enclosed within the drainage channel that between electric apparatus, top top cover and roof rail are installed respectively.Its effect is the collection rainy day to flow to the rainwater between electric apparatus, by drainageway own, the rainwater of collection is discharged to outside car body.
Accompanying drawing explanation
Fig. 1 is top cover and the roof rail side cross-sectional schematic of electric locomotive.
Fig. 2 is the partial schematic diagram that locomotive depot adopts shutoff rainwater to enter described in background technology.
Fig. 3 is the utility model drainage channel installation site partial schematic diagram.
Fig. 4 Fig. 5 is the utility model drainage channel structure figure.
In figure, 1. roof rail, 2. top cover, 3. between electric apparatus, 4. rubber weather strip, 5. polyurethane sealant, 6. top cover gusset, the drainage channel of 7. installing on top cover gusset, the large drainage channel of 8. installing in roof rail.
The specific embodiment
In Fig. 1, locomotive header 2. with roof rail this structure design 1., generally rainwater can be discharged smoothly.Because locomotive operation need to ventilate to electrical equipment coolingly, between electric apparatus, 3. air intake is not smooth, forms negative pressure, make rainwater be easy to by top cover 2. with support the gap place of top cover roof rail 2. between 1. contacting and be inhaled into and flow to the inside.
In Fig. 2, adopt sealing band 4. and polyurethane sealant 5. shutoff top cover 2. and gap and the notch of roof rail between 1., prevent entering of rainwater.Because locomotive operation exists vibration and impacts, through one section of locomotive operation after the time rubber strip 4. 5. all there is be full of cracks or embrittlement with polyurethane sealing band and infilter rainwater.
In Fig. 3, the utility model has adopted in roof rail and 1. on the facade of inner side, the large drainage channel of Fig. 4 rubber system has been installed 8., and its effect is between electric apparatus, 3. to form under negative pressure state, make to flow into top cover and 2. on face, drip fallen rainwater, by this drainage channel, 8. collect and discharge.
In Fig. 3, be arranged on roof rail and 1. designed again a little drainage channel in the facade inboard 8. of drainage channel of inner side, its effect is that to make to flow to the draught head that the rainwater in groove is subject to less, is difficult for being subject to barometric pressure effect again outside spout, but rainwater flows to two side channel mouths along drainage channel, discharges.
In Fig. 3, again design and installation one top cover gusset 6. the drainage channel on limit 7., its effect is the rainwater that 6. splash is flowed down on face to top cover gusset, by this drainage channel, is 7. collected and is discharged.
In addition, Fig. 4 Fig. 5 drainage channel, owing to not 2. pushed and solar ulatraviolet radiation by top cover, can greatly extend service life.In the SS4G of Hu Dong locomotive depot of Jing Datong District electric locomotive, the trial running of nearly 2 years, proves and the utlity model has certain practical application effect.
In Fig. 4 Fig. 5, it is the constructional drawing that this set of drainage channel is actual employing.
Claims (1)
1. a power locomotive top enters rain collection drainage channel, it is characterized in that, described drainage channel is included in the outside, inner side of grooved roof rail and has installed one across crossing top cover gusset, for collecting and discharge splash, to top cover face, drip fallen large drainage channel, inside this large drainage channel, facade has designed again one and can reduce negative pressure effect, and can collect and discharge by the come in little drainage channel of rainwater of roof rail face upper reaches, and be arranged on top cover gusset limit, for collecting and discharge splash to the drainage channel of the rainwater flowing down on top cover gusset.
