Abstract
The utility model relates to the technical field of diesel engines, in particular to a rain cover for an exhaust passage of a locomotive diesel engine. The rain cover for the exhaust passage of the locomotive diesel engine comprises a rain ceiling, wherein the rain ceiling is connected with a fastening cushion block and a U-shaped mounting groove through bolts; the fastening cushion block is arranged at the bottom of the rain ceiling; the U-shaped mounting groove is formed in the fastening cushion block; the bolt is connected with the fastening cushion block; and the rain ceiling is fixed in the U-shaped mounting groove. The rain cover for the exhaust passage of the locomotive diesel engine has the characteristics of simple structure, low cost and convenience in installing, and has a very good rain-proof effect in practical use.
Description
Technical field
The utility model relates to a kind of rain cover, relates in particular to a kind of diesel engine of locomotive air outlet flue rain cover.
Background technique
Usually adopt direct-exhausting type or exhaust duct to install again the mode of case outward additional both at home and abroad.Direct-exhausting type is that the air outlet flue outlet is blocked without any towards the sky.Diesel engine allows a small amount of rainwater to enter air outlet flue now, but a large amount of rainwater can enter power house by the gap between diesel engine exhaust port and roof, makes to produce a large amount of ponding in power house, easily causes corrosion.The mode that air outlet flue installs case outward additional is to rely on the waste gas venetian blind that will keep off the rain to blow open when internal combustion engine, reaches the purpose of exhaust, but the diesel exhaust gas back pressure is increased, and has affected the power performance of internal-combustion engine, makes the internal combustion engine state deteriorating.
Summary of the invention
The technical problems to be solved in the utility model is: the diesel exhaust gas road enters a large amount of ponding, easily cause corrosion, the mode that air outlet flue installs case outward additional is to rely on the waste gas venetian blind that will keep off the rain to blow open when internal combustion engine, reach the purpose of exhaust, but the diesel exhaust gas back pressure is increased, affected the power performance of internal-combustion engine, made the internal combustion engine state deteriorating, a kind of diesel engine of locomotive air outlet flue rain cover is provided.
In order to overcome the defective that exists in background technique, the technological scheme that its technical problem that solves the utility model adopts is: this diesel engine of locomotive air outlet flue rain cover comprises rainproof ceiling, rainproof ceiling is bolted fastening cushion block, bolt is placed in U-shaped mounting groove, described fastening cushion block is placed in bottom rainproof ceiling, described U-shaped mounting groove is placed in fastening cushion block, and described bolt connects fastening cushion block, and rainproof ceiling is fixed on U-shaped mounting groove.
The beneficial effects of the utility model are: this diesel engine of locomotive air outlet flue rain cover has characteristics simple in structure, that cost is low, easy for installation, and the rainproof effect in practice is also fine.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, ceiling, 2, bolt, 3, fastening cushion block, 4, U-shaped mounting groove.
Embodiment
Fig. 1 is structural representation of the present utility model, comprise rainproof ceiling 1, rainproof ceiling 1 connects fastening cushion block 3 by bolt 2, bolt 2 is placed in U-shaped mounting groove 4, described fastening cushion block 3 is placed in rainproof ceiling 1 bottom, described U-shaped mounting groove 4 is placed in fastening cushion block 3, and described bolt 2 connects fastening cushion block 3, and rainproof ceiling 1 is fixed on U-shaped mounting groove 4.
diesel engine of locomotive air outlet flue rain cover is comprised of four parts, as shown in Figure 1, rainproof ceiling 1, bolt 2, fastening cushion block 3 and U-shaped mounting groove 4, rainproof ceiling 1 mainly plays and prevent that rainwater from entering in power house from the gap of all angles by diesel engine exhaust port and roof, by connecting bolt 2 and fastening cushion block, rainproof ceiling is fixed on mounting groove, U-shaped mounting groove 4 is except fixing rainproof ceiling 1, a large amount of rainwater tricklings that can also prevent roof enter in power house, whole apparatus structure is simple, practical, and very low of cost, mount and dismount all very convenient.Fastening cushion block 3 is movable blocks, when bolt tightening, fixes rainproof ceiling 1 by pretightening force, can adjust at any time the position in installation process, reduces installation difficulty.
This diesel engine of locomotive air outlet flue rain cover has characteristics simple in structure, that cost is low, easy for installation, and the rainproof effect in practice is also fine.
