Description

Technical Field

[0001] The utility model belongs to the field of rail transportation equipment, in particular to a ventilation device for a locomotive battery box. Background Art

[0002] In modern railway transportation, the reliable operation of locomotives is crucial to the safety and efficiency of the entire transportation system. As an important part of the locomotive, the battery box plays a key role in providing power for the locomotive.

[0003] The battery will produce a certain amount of gas during the charging and discharging process. In order to discharge this gas, breathing holes are usually reserved on the battery box. However, these breathing holes are directly exposed to the external environment without any protection measures. As the locomotive runs at high speed, a significant pressure difference will be generated between the inside and outside of the box. This pressure difference will not only affect the normal operation of the battery, but also bring other hidden dangers.

[0004] Especially during the operation of the locomotive, due to the high dust on the line, the dust from the outside can easily enter the battery box through the breathing holes. The dust gradually accumulates on the surface of the battery, seriously affecting the performance and life of the battery. The accumulation of dust may also cause electrical failures, increasing the risk of locomotive operation. Utility Model Content

[0005] The utility model aims to provide a locomotive battery box ventilation device to solve the above-mentioned problems in the prior art.

[0006] A locomotive battery box ventilation device is provided, comprising:

[0007] A ventilation device body, wherein a ventilation passage is formed inside the ventilation device body, and a drawer opening is provided on a side wall of the ventilation device body near one end of the air outlet;

[0008] An air inlet grille, which is arranged at the air outlet of the ventilation device body;

[0009] A filter assembly is provided, wherein the filter assembly movably passes through the drawer opening and is slidably connected to the ventilation device body.

[0010] Furthermore, the installation opening of the ventilation device body is provided with a mounting flange, and the mounting flange is provided with a plurality of magnetic modules along the circumference. The magnetic modules are provided with studs, which are connected to the mounting flange through studs and nuts. The mounting flange is directly adsorbed on the surrounding of the reserved breathing hole on the surface of the box through the magnetic modules, thus solving the problem of difficult installation and operation of the ventilation device.

[0011] Further, a partition plate is arranged in the ventilation channel. The partition plate continuously extends from the installation opening to the air outlet and divides the ventilation channel into an air inlet channel and an air outlet channel respectively. The partition plate divides the ventilation channel into two independent spaces.

[0012] Further, the area of the air outlet of the ventilation device main body occupied by the input port of the air inlet channel is larger than the area of the air outlet of the ventilation device main body occupied by the output port of the air outlet channel.

[0013] Further, the ratio of the area of the air outlet of the ventilation device main body occupied by the input port of the air inlet channel is 7 - 9:10.

[0014] Further, the area of the installation opening of the ventilation device main body occupied by the output port of the air inlet channel is smaller than the area of the installation opening of the ventilation device main body occupied by the input port of the air outlet channel.

[0015] Further, the ratio of the area of the installation opening of the ventilation device main body occupied by the output port of the air inlet channel is 1 - 3:10.

[0016] By controlling the areas of air inlet and air outlet at both ends of the ventilation device main body, the separate flow of clean air and the gas in the box can be realized, preventing the two from mixing and re - entering the box.

[0017] Further, the filtering component includes a dust filtering module and a by - product filtering module. The dust filtering module is located at the input port of the air inlet channel, and the by - product filtering module is located at the output port of the air outlet channel. The by - product filtering module can filter and process the gas generated by the storage battery and discharge the purified gas.

[0018] Further, the filtering component further includes a frame body. The frame body movably penetrates through the drawer opening and is slidably connected to the ventilation device main body. The dust filtering module and the by - product filtering module are detachably connected to the frame body. After the frame body is pulled out through the drawer - type structure, the dust filtering module and the by - product filtering module can be replaced separately, improving the utilization rate of the filtering component.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] During the operation of the locomotive, due to the pressure difference generated inside and outside the box, natural wind enters from the air outlet of the ventilation device main body. The air inlet grille can effectively block larger - sized particles such as gravel, forming the first - stage filtering device. The high - efficiency filtering device is installed in the ventilation device main body by a drawer - type structure, which can filter fine dust. The filter element can be replaced by simply pulling it out, making maintenance and repair convenient. Description of the Drawings

[0026] Obviously, the accompanying drawings in the following description are only some examples or embodiments of the present application. For those of ordinary skill in the art, the present application can also be applied to other similar scenarios based on these drawings without creative efforts. In addition, it can also be understood that although the efforts made in this development process may be complex and lengthy, for those of ordinary skill in the art related to the content disclosed in the present application, some designs, manufacturing or production changes made on the basis of the technical content disclosed in the present application are only conventional technical means and should not be understood as the content disclosed in the present application being insufficient.

[0027] However, there will be cases where unnecessary detailed descriptions are omitted. For example, there are cases where detailed descriptions of well-known matters are omitted and repeated descriptions of actually identical structures are omitted. This is to avoid the following description from becoming unnecessarily lengthy and to facilitate the understanding of those skilled in the art. In addition, the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present application and are not intended to limit the subject matter recited in the claims.

[0028] Please refer to Figure 1-2As shown in the figure, in the embodiment of the present utility model, a ventilation device for a locomotive battery box includes a ventilation device main body 1, an air inlet grille 2, and a filtering component 3. A ventilation channel 11 is formed inside the ventilation device main body 1, and a drawer opening 12 is provided on the side wall of the ventilation device main body 1 near the air outlet. The air inlet grille 2 is arranged at the air outlet of the ventilation device main body 1. The filtering component 3 movably penetrates through the drawer opening 12 and is slidably connected to the ventilation device main body 1.

[0029] The aperture of the air inlet grille 2 is relatively large, which can filter large-particle sand and gravel to ensure the ventilation volume. The filtering component 3 is used to filter small-particle sand and dust to prevent the sand and dust from entering the box body. By filtering the natural fresh air entering the battery box, the interior of the locomotive battery box is kept clean, and the external dust of the locomotive is prevented from entering the battery box, affecting the use of the battery cells. The filtering component 3 is installed in the ventilation device main body 1 in a drawer-type structure and can be replaced by simply pulling it out, which is convenient for maintenance.

[0030] The ventilation device main body 1 and the box body can be fixedly connected by bolts or detachably connected through other components. Specifically, an installation flange 13 is provided at the installation opening of the ventilation device main body 1, and a plurality of magnetic attraction modules 14 are arranged along the circumference of the installation flange 13. The magnetic attraction modules 14 adsorb the installation flange 13 and the box body together by magnetic force, or the magnetic attraction modules 14 can be fixed to the installation flange 13 by bolts and then adsorbed to the box body. The installation flange 13 is directly adsorbed around the reserved breathing holes on the surface of the box body, solving the problem of the narrow space around the battery box body and the difficulty of installation operation.

[0031] In one embodiment, a partition plate 4 is arranged in the ventilation channel 11. The partition plate 4 continuously extends from the installation opening to the air outlet and divides the ventilation channel 11 into an air inlet channel 111 and an air outlet channel 112 respectively. The partition plate 4 divides the ventilation channel 11 into two independent spaces. When the external air pressure is greater than the internal air pressure, the external air enters from the air inlet channel 111, and after being filtered, it enters the interior of the box body; when the external air pressure is less than the internal air pressure, the internal gas carrying the battery by-product gas enters from the air outlet channel 112 and finally is discharged from the output port. The clean gas and the by-product gas are separated and transported.

[0032] Furthermore, the area of the air outlet of the ventilation device main body 1 occupied by the input port of the air inlet channel 111 is larger than the area of the air outlet of the ventilation device main body 1 occupied by the output port of the air outlet channel 112. When there is an air pressure difference inside and outside the box body, the external air mainly enters from the input port of the air inlet channel 111, reducing the probability of air entering from the output port of the air outlet channel 112.

[0033] Furthermore, the area of the installation opening of the ventilation device main body 1 occupied by the output port of the air inlet channel 111 is smaller than the area of the installation opening of the ventilation device main body 1 occupied by the input port of the air outlet channel 112. When there is an air pressure difference inside and outside the box body, the internal by-product gas mainly enters from the input port of the air outlet channel 112, reducing the probability of the by-product gas entering from the output port of the air inlet channel 111.

[0034] Through the cooperation of the above two further embodiments, the layered control of the air flow can be achieved, ensuring that the external air and the internal air travel along a predetermined route.

[0035] Furthermore, the filter assembly 3 includes a dust filtration module 31 and a by-product filtration module 32. The dust filtration module 31 is located at the input port of the air inlet channel 111, and the by-product filtration module 32 is located at the output port of the air outlet channel 112. When the internal by-product gas of the box body is discharged from the air outlet channel 112, the by-product filtration module 32 can filter and process the gas generated by the storage battery, preventing these unpurified gases from being directly discharged into the atmosphere. The external air enters the air inlet channel 111 after being filtered by the dust filtration module 31.

[0036] The filter assembly 3 further includes a frame body 33. The frame body 33 movably penetrates through the drawer opening 12 and is slidably connected to the ventilation device main body 1. The dust filtration module 31 and the by-product filtration module 32 are detachably connected to the frame body 33. Since the service lives of the dust filtration module 31 and the by-product filtration module 32 are different, after the frame body 33 is pulled out through the drawer-type structure, the dust filtration module 31 and the by-product filtration module 32 can be replaced separately, improving the utilization rate of the filter assembly 3.

[0037] It should be noted that the present application is not limited to the above embodiments. The above embodiments are only examples, and embodiments having the same constitution and the same effect as the technical idea within the technical solution scope of the present application are all included in the technical scope of the present application. In addition, within the scope not departing from the gist of the present application, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways constructed by combining some constituent elements of the embodiments are also included in the scope of the present application.
