Description

Technical Field

[0001] The utility model belongs to the technical field of dust and rain protection, and particularly relates to a dust and rain protection device for power generation in the living area of a train. Background Art

[0002] In a train, the cab at the tail during the running of the train is the living area for the driver. However, there is no domestic power supply in this living area during the running process. In order to avoid the severe cold in winter and the intense heat in summer, generally, a power generation device is connected to the wheel part of the vehicle to convert the mechanical energy during the running of the vehicle into electrical energy.

[0003] In order to ensure that the generator is not interfered during use, generally, a protective cover is used to protect the generator from rain and dust. However, due to the sealing of the cover body, it is not conducive to the heat dissipation of the generator. Content of the Utility Model

[0004] Aiming at the problem that the protective cover of the generator in the prior art is limited by the sealing of the cover body and is not conducive to the heat dissipation of the generator, the utility model provides a dust and rain protection device for power generation in the living area of a train, and the specific technical solutions are as follows:

[0005] The dust and rain protection device for power generation in the living area of a train includes a cover body and an end cover covering the opening end of the cover body. A bearing hole is opened on the end face of the cover body far from the end cover. A generator is installed on the end face of the end cover facing the cover body. An inward-extending baffle is provided on the inner wall of the bottom end of the cover body. In the installation state, the baffle abuts against the generator and forms a one-way channel in the cover body. Two air vents are spaced apart on the bottom of the cover body, and the two air vents are symmetrically arranged relative to the baffle.

[0006] As a further technical solution of the utility model, a first sealing piece and a second sealing piece are sequentially and spaced apart inside the air vent. Both the first sealing piece and the second sealing piece cooperate with the baffle and the cover body to form a sealed space. A first notch communicating with the air vent is opened on the first sealing piece, and a second notch communicating with the first notch is opened on the second sealing piece. Along the circumferential path of the cover body, the first notch and the second notch are arranged in a staggered manner.

[0007] As a further technical solution of the utility model, along the axial path of the cover body, the first notch and the second notch are arranged in a staggered manner.

[0008] As a further technical solution of the utility model, the position of the air vent corresponds to that of the second notch.

[0009] As a further technical solution of the utility model, several groups of the first sealing piece and the second sealing piece are provided and correspond to each other one by one, and several groups of the first sealing piece and the second sealing piece are arranged alternately.

[0010] As a further technical solution of the utility model, dust filter nets are installed in the air vent, the first notch, and the second notch.

[0011] The beneficial effects of the present utility model are as follows:

[0012] In this application, by opening an air vent at the bottom of the cover body, it not only prevents rainwater from entering but also enables ventilation and heat dissipation. Moreover, a first notch and a second notch that are offset from each other are provided inside the air vent, so that the intake passage is tortuous, which can block the water splashed from the bottom up when the train passes over the ground, thus preventing the rainwater accumulated on the road surface from splashing into the cover body through the air vent.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0019] In view of the fact that in the prior art, the protection cover of the generator is limited by the sealing of the cover body, which is not conducive to the heat dissipation of the generator; in this application, a ventilation opening is opened at the bottom of the cover body, which not only prevents rainwater from entering but also enables ventilation.

[0020] Figure 1 Shows a schematic diagram of the overall structure of the power generation dust and rain protection device for the train living area; Figure 1 In this, the power generation dust and rain protection device for the train living area includes a cover body 200 and an end cover 100 covering the opening end of the cover body 200. A bearing hole 210 is opened on the end face of the cover body 200 away from the end cover 100, and a generator 300 is installed on the end face of the end cover 100 facing the cover body 200; the input shaft of the external wheel is inserted into the cover body 200 through the bearing hole 210 and connected to the generator 300. When the train is running, the input shaft is driven by the wheel to rotate and drive the generator 300 to convert mechanical energy into electrical energy.

[0021] Figure 2Shows a schematic internal structure diagram of the cover 200; Figure 2 Among them, the inner wall at the bottom end of the cover 200 has an inwardly extending baffle 220. In the installed state, the baffle 220 abuts against the trigger motor 300 and forms a one-way channel 230 inside the cover 200. Two air vents 240 are spaced apart at the bottom of the cover 200, and the two air vents 240 are symmetrically arranged relative to the baffle 220; the above-mentioned installed state refers to the state after the generator 300 is installed in the cover 200. At this time, the two air vents 240 are spaced on both sides of the baffle 220, one of which serves as the air inlet and the other as the air outlet. When cold air enters from one air vent 240, it needs to travel along the trajectory of the one-way channel 230 and be discharged from the other air vent 240. During this travel trajectory, the one-way channel 230 can force the cold air to go around the generator 300 for one week to achieve comprehensive heat dissipation. Moreover, since both air vents 240 are provided at the bottom of the cover 200, they can be protected by the cover 200 to avoid rainwater from entering.

[0022] It should be noted that in this application, among the two air vents 240, when one serves as the air inlet, the other serves as the air outlet, but no specific restrictions are imposed on their functions.

[0023] Figure 3 Shows a schematic structural diagram of the first sealing piece 250 and the second sealing piece 260; Figure 3 Combined Figure 2, inside the air inlet 240, a first sealing piece 250 and a second sealing piece 260 are arranged at intervals in sequence. Both the first sealing piece 250 and the second sealing piece 260 cooperate with the baffle 220 and the cover 200 to form a sealed space. A first notch 251 communicating with the air inlet 240 is formed on the first sealing piece 250, and a second notch 261 communicating with the first notch 251 is formed on the second sealing piece 260. Along the circumferential path of the cover 200, the first notch 251 and the second notch 261 are arranged in a staggered manner; after the gas enters from the air inlet 240, it needs to pass through the first notch 251 and the second notch 261 in sequence to enter the interior of the cover 200 for circulation. The staggered arrangement of the first notch 251 and the second notch 261 in the circumferential direction means that in the cross-section, when a projection is formed by emitting from the center of the circle to the curved surface, there is no overlapping part between the first notch 251 and the second notch 261, making the gas passage more tortuous, which can block the water splashed from the bottom up when the train travels on the ground, so as to prevent the rainwater accumulated on the road surface from splashing into the cover 200 through the air inlet 240; along the axial path of the cover 200, the first notch 251 and the second notch 261 are arranged in a staggered manner; here, the staggered arrangement of the first notch 251 and the second notch 261 in the axial direction means that on the horizontal projection plane, there is no overlapping part between the first notch 251 and the second notch 261, so as to further make the gas passage more winding; the position of the air inlet 240 corresponds to that of the second notch 261. Here, the correspondence means that the air inlet 240 and the second notch 261 are on the same radius. This is because the gas finally enters the cover 200 through the second notch 261. If the second notch 261 corresponds to the air inlet 240, since the air inlet 240 is arranged at the bottom of the cover 200, the second notch 261 can also be arranged in contact with the baffle 220 to ensure the length of the gas path around the generator 300; several groups of the first sealing piece 250 and the second sealing piece 260 are arranged and correspond to each other one by one. The several groups of the first sealing piece 250 and the second sealing piece 260 are arranged alternately; for the convenience of observation, in Figure 3 , in this embodiment, only one group of the first sealing piece 250 and one group of the second sealing piece 260 are shown. In some other embodiments, the number of the first sealing piece 250 and the second sealing piece 260 is not specifically limited, but they must correspond to each other one by one. That is to say, the number of the first sealing piece 250 and the second sealing piece 260 needs to be the same. In this way, the gas will still finally enter the cover 200 through the second notch 261; dust filters 270 are installed in the air inlet 240, the first notch 251 and the second notch 261; the dust filters 270 are used to block impurities such as dust mixed in the introduced gas to achieve dust prevention.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
