Description

Technical Field

[0001] The utility model provides a ventilation duct structure for a diesel locomotive, belonging to the technical field of ventilation duct structures. Background Art

[0002] A diesel locomotive is a locomotive that uses a diesel engine as the motive force to drive the wheels through a transmission device. According to the type of fuel used by the diesel engine on the locomotive, most of the diesel locomotives used on my country's railways are equipped with diesel engines. Ventilation ducts are essential in diesel locomotives to keep the air inside the locomotive unobstructed.

[0003] The existing ventilation duct structure installed on diesel locomotives can basically meet the use needs, but there are still certain defects: when in use, the ventilation duct is often kept unobstructed, which not only makes it easy for criminals to escape along the ventilation duct of the diesel locomotive, but also allows animals to come and go freely in the ventilation duct; and when the ventilation duct structure is ventilated, the flow rate of wind in the ventilation duct is often average, and ventilation cannot be carried out in time, and the ventilation rate needs to be improved. Based on this, the utility model provides a ventilation duct structure for diesel locomotives. Utility Model Content

[0004] The technical problem solved by the utility model is that: the ventilation duct is kept unobstructed, which not only makes it easy for criminals to escape along the ventilation duct of the internal combustion locomotive, but also allows animals to come and go freely in the ventilation duct; the flow rate of wind in the ventilation duct is often average, and timely ventilation is impossible, and the ventilation rate needs to be improved.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a ventilation duct structure of a diesel locomotive, comprising a ventilation duct, a support ring is provided between the inner walls of the ventilation duct, a support plate is provided between the inner walls of the support ring, a conical platform is provided on one side of the support plate, a rotating rod rotatably connected to the side wall of the support plate is provided at the center of the side wall of the conical platform, a spiral protrusion is provided on the outer arc wall of the conical platform, and a plurality of baffle rods are symmetrically provided between the inner wall of the support ring and the side wall of the support plate.

[0006] Furthermore, the ventilation duct is made of stainless steel, and the support ring is welded and fixed to the inner wall of the ventilation duct.

[0007] Furthermore, the rotating rod is rotatably connected to the side wall of the support plate via a bearing.

[0008] Furthermore, the tip of the conical platform is in the shape of a blunt round head.

[0009] Furthermore, the ventilation duct is provided with an air inlet on one side and an air outlet on the other side, the conical platform is arranged on the side close to the air inlet, and the tip of the conical platform is close to the air inlet of the ventilation duct.

[0010] Beneficial effects of the utility model:

[0011] 1. By blocking the ventilation duct with a blocking rod, it can not only effectively prevent criminals from escaping through the ventilation duct of the diesel locomotive, but also prevent animals from coming and going freely in the ventilation duct;

[0012] 2 When the ventilation duct is ventilated, the wind flows from the air inlet to the air outlet of the ventilation duct. At this time, the flowing wind will pass through the cone table, and the flowing wind drives the cone table to rotate, so that the spiral protrusion on the outer arc wall of the cone table rotates, and the wind flows along the rotating spiral protrusion, so that the wind swirls and flows outward, speeding up the flow rate of the wind, thereby effectively improving the ventilation rate and keeping the air inside the diesel locomotive unobstructed.

[0020] As an optional embodiment, the ventilation duct 1 is made of stainless steel, and the support ring 2 is welded and fixed to the inner wall of the ventilation duct 1 .

[0021] According to the attached Figure 4 As shown: the rotating rod 5 and the side wall of the supporting plate 3 are rotatably connected via a bearing 8, so as to ensure that the rotating rod 5 can effectively rotate, thereby driving the cone-shaped platform 4 to rotate.

[0022] According to the attached Figure 2 As shown: the tip of the conical platform 4 is blunt and round, which plays a role in diverting the discharged wind.

[0024] Principle of the utility model

[0025] When in use, the ventilation duct is installed in the internal combustion locomotive. By using the blocking rod 7 to block the ventilation duct 1, it can not only effectively prevent criminals from escaping along the ventilation duct 1 of the internal combustion locomotive, but also prevent animals from coming and going freely in the ventilation duct 1. When the ventilation duct is ventilated, wind flows from the air inlet 9 to the air outlet 10 of the ventilation duct. At this time, the flowing wind will pass through the conical platform 4. Under the action of the bearing 8, the flowing wind drives the conical platform 4 to rotate, so that the spiral protrusion 6 on the outer arc wall of the conical platform 4 rotates, and the wind flows along the rotating spiral protrusion 6, so that the wind swirls and flows outward, accelerating the flow rate of the wind, thereby effectively improving the ventilation rate and keeping the air inside the internal combustion locomotive unobstructed.
