Description

Technical Field

[0001] The present disclosure relates to the technical field of filter devices, and more particularly to a filter and a locomotive. Background Art

[0002] The rain test is an important task to test the sealing performance of the locomotive. By simulating severe weather such as heavy rain and rainstorms during locomotive operation, quality risks such as leakage and water seepage can be discovered and eliminated in advance to ensure the safe operation of the locomotive on the line.

[0003] During the rain test before the locomotive leaves the factory, there is occasionally a problem of rain leakage at the filter installation point. The current commonly used method to solve the leakage problem is to apply glue to the leaking points in a targeted manner. However, this method has the following disadvantages: First, it affects the appearance. If there are many leaking points or the distance between the leaking points is long, the leakage will be more obvious after applying the glue, affecting the overall appearance of the locomotive; second, after the locomotive leaves the factory, due to the relatively harsh working environment, the sealant will be exposed to high temperatures and exposure in summer or severe cold and frost in winter. As time goes by, the sealing effect will decrease rapidly, which can easily cause sealing failure. Summary of the Invention

[0004] The purpose of the present disclosure is to provide a filter and a locomotive to alleviate the technical problem in the prior art that the method of applying glue to seal the leakage point of the filter easily leads to sealing failure.

[0005] Based on the above-mentioned purpose, the present disclosure provides a filter, including a frame and a filter body, the filter body is connected to the frame, the filter body is provided with a first drain board, a first seal is provided between the first drain board and the frame, and the first seal can abut against the inner surface of the frame; the frame is provided with a second drain board, a second seal is provided between the second drain board and the filter body, and the second seal can abut against the inner surface of the filter body; wherein, the second drain board and the first drain board are spaced apart along the height direction of the filter.

[0006] In one embodiment of the present disclosure, the first sealing member is provided with a first sealing groove, and the free end of the first drain plate is inserted and fixed in the first sealing groove; the second sealing member is provided with a second sealing groove, and the free end of the second drain plate is inserted and fixed in the second sealing groove.

[0009] In one embodiment of the present disclosure, the first drainage plate and the filter body are integrally formed.

[0010] In one embodiment of the present disclosure, the second drain plate is integrally formed with the frame.

[0011] In one embodiment of the present disclosure, the first drain plate is located above the second drain plate.

[0012] In one embodiment of the present disclosure, the filter body and the frame are connected by fasteners.

[0013] In one embodiment of the present disclosure, the filter body is hinged to the frame;

[0014] The filter further comprises a telescopic device, one end of which is hinged to the filter body and the other end of which is hinged to the frame, so that the filter body can rotate relative to the frame around the axis of the hinge shaft between the filter body and the frame.

[0015] In one embodiment of the present disclosure, the filter further includes a locking device, and the locking device is used to press and fix the filter body to the frame.

That is, the entire filter adopts a "double seal + double drainage" parallel combination sealing method. As long as all links do not fail simultaneously, the sealing will not fail, thereby improving the overall sealing reliability of the filter. When in use, the filter is installed on the side wall of a locomotive. When the locomotive is subjected to a rain test, a large amount of rainwater will enter the gap between the upper end of the filter and the side wall of the vehicle body. The rainwater will first fall on the first drain plate. Because the first seal is provided between the first drain plate and the frame, the first seal can abut against the inner surface of the frame. When the first seal has good sealing performance, the rainwater will be directly drained along the first drain plate.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions of the present disclosure in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

Therefore, they should not be construed as limitations on this disclosure. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this disclosure, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on the specific circumstances.

[0031] See also Figures 1 to 6As shown, this embodiment provides a filter, including a frame 200 and a filter body 100, the filter body 100 is connected to the frame 200, the filter body 100 is provided with a first drain board 101, a first seal 102 is provided between the first drain board 101 and the frame 200, and the first seal 102 can abut against the inner surface of the frame 200; the frame 200 is provided with a second drain board 201, a second seal 202 is provided between the second drain board 201 and the filter body 100, and the second seal 202 can abut against the inner surface of the filter body 100; wherein, the second drain board 201 and the first drain board 101 are spaced apart along the height direction of the filter.

[0032] The filter provided in this embodiment forms a first seal and drainage by providing a first drain plate 101 and a first seal 102, and forms a second seal and drainage by providing a second drain plate 201 and a second seal 202. That is, the entire filter adopts a "double seal + double drainage" parallel combination sealing method. As long as all links do not fail at the same time, the seal will not fail, thereby improving the overall sealing reliability of the filter. During use, the filter is mounted on the side wall of a locomotive. When the locomotive is subjected to a rain test, a large amount of rainwater will enter the gap between the upper end of the filter and the side wall of the vehicle body. The rainwater will first fall on the first drain plate 101. Because a first seal 102 is provided between the first drain plate 101 and the frame 200, the first seal 102 can abut against the inner surface of the frame 200. When the first seal 102 has a good sealing performance, the rainwater will be directly drained along the first drain plate 101. If the first seal 102 fails, the rainwater cannot be drained away from the first drain plate 101 in time, and some rainwater will enter the second drain plate 201. Because a second seal 202 is provided between the second drain plate 201 and the filter body 100, the second seal 202 can abut against the inner surface of the filter body 100, ensuring that the rainwater can be drained along the second drain plate 201. If the second seal 202 on the second drain plate 201 is sealed well, the overall seal of the filter will not fail.

[0033] Illustratively, the first drain plate 101 is located above the second drain plate 201 .

[0034] The height direction of the filter refers to the direction that is consistent with the height direction of the vehicle body after the filter is installed on the side wall of the vehicle body, that is, the height direction of the filter is consistent with the height direction of the vehicle body.

[0035] In one embodiment, see Figure 2As shown, the filter body 100 includes a panel 103, the frame 200 includes a back plate 203, the first drain plate 101 is fixedly connected to the panel 103, and the first seal 102 can abut against the surface of the back plate 203 facing the filter body 100; the second drain plate 201 is fixedly connected to the back plate 203, and the second seal 202 can abut against the surface of the panel 103 facing the frame 200. For details, see Figure 5 As shown, the first drain plate 101, the portion of the front panel 103, and the portion of the back panel 203 located above the first drain plate 101 together form a first drain trough, while the second drain plate 201, the portion of the front panel 103 and the portion of the back panel 203 located above the second drain plate 201 together form a second drain trough. When the first seal 102 is properly sealed, rainwater will drain directly along the first drain trough. If the first seal 102 fails, rainwater will not be able to drain from the first drain trough in a timely manner, and some rainwater will enter and drain along the second drain trough. If the second seal 202 on the second drain plate 201 is properly sealed, the overall filter seal will not fail.

[0036] In one embodiment, the first sealing member 102 is provided with a first sealing groove, and the free end of the first drain plate 101 is inserted and fixed in the first sealing groove; the second sealing member 202 is provided with a second sealing groove, and the free end of the second drain plate 201 is inserted and fixed in the second sealing groove.

[0037] In some embodiments, see, for example, Figure 2 As shown, the first drainage board 101 includes a first plate body 1011 and a first guide plate 1012 extending downwardly from both ends of the first plate body 1011. That is, the first drainage board 101 includes a first plate body 1011 and two first guide plates 1012. The two first guide plates 1012 are respectively located on both sides of the first plate body 1011. Exemplarily, the first plate body 1011 and the two first guide plates 1012 are integrally formed. This method can reduce the risk of leakage and ensure that rainwater is quickly discharged under the guidance of the first guide plates 1012.

[0038] In one embodiment, the first drain plate 101 and the filter body 100 are integrally formed, which can reduce the risk of leakage.

[0039] In one embodiment, the second drain plate 201 is integrally formed with the frame 200 , which can reduce the risk of leakage.

[0040] In some embodiments, see Figure 3As shown, the second drainage board 201 includes a second plate body 2011 and second guide plates 2012 extending downwardly from both ends of the second plate body 2011. That is, the second drainage board 201 includes a second plate body 2011 and two second guide plates 2012. The two second guide plates 2012 are respectively located on both sides of the second plate body 2011. Exemplarily, the second plate body 2011 and the two second guide plates 2012 are integrally formed. This method can reduce the risk of leakage and ensure that rainwater is quickly discharged under the guidance of the second guide plates 2012.

[0041] In some embodiments, the second drain plate 201 forms a part of the frame 200 .

[0042] In one embodiment, the first sealing member 102 is an Ω-shaped sealing strip, and / or the second sealing member 202 is an Ω-shaped sealing strip.

[0043] In some embodiments, the first seal 102 is an Ω-shaped sealing strip, and the second seal 202 is an Ω-shaped sealing strip. The first seal 102 and the second seal 202 both use Ω-shaped sealing strips instead of traditional flat rubber strips, which can compensate for poor sealing caused by manufacturing errors to a certain extent.

[0044] Taking the first seal 102 as an example, the Ω-shaped sealing strip has a first sealing groove, and the groove wall of the first sealing groove has a serrated protrusion. For example, the serrated protrusion is arranged on the inner wall of the Ω-shaped sealing strip. When the free end of the first drain board 101 is inserted into the first sealing groove, the serrated structure is in close contact with the surface of the first drain board 101, thereby increasing the connection firmness and sealing performance, and effectively preventing the first seal 102 from separating from the first drain board 101.

[0045] In other embodiments, one of the first sealing member 102 and the second sealing member 202 is an Ω-shaped sealing strip.

[0046] In one embodiment, see Figure 2 and Figure 6 As shown, the frame 200 is used to connect with the vehicle body mounting plate 600. A positioning boss 204 is provided on the side of the frame 200 away from the filter body 100. The positioning boss 204 can abut against the vehicle body mounting plate 600. A sealing gasket 700 is provided between the frame 200 and the vehicle body mounting plate 600.

[0047] Specifically, the back plate 203 of the frame 200 is used to connect to the vehicle body mounting plate 600. For example, the back plate 203 is fixedly connected to the vehicle body mounting plate 600 by fasteners such as bolts and nuts. Figure 6As shown, in order to ensure the sealing between the frame 200 and the vehicle body mounting plate 600, a sealing gasket 700 is arranged between the frame 200 and the vehicle body mounting plate 600. In order to effectively avoid the problem of local sealing failure caused by excessive torque during the process of fastening the frame 200 to the vehicle body mounting plate 600, a positioning boss 204 is provided on the side of the back plate 203 facing away from the filter body 100. When the surface of the positioning boss 204 facing away from the back plate 203 abuts against the vehicle body mounting plate 600, the frame 200 stops moving toward the direction close to the vehicle body mounting plate 600, thereby not continuing to squeeze the sealing gasket 700, thereby ensuring the sealing between the frame 200 and the vehicle body mounting plate 600.

[0048] In some embodiments, the sealing gasket 700 is made of EPDM (Ethylene-Propylene-Diene Monomer). For example, the thickness of the sealing gasket 700 is 8 mm, and the thickness of the positioning boss 204 is 3 mm. The thickness of the positioning boss 204 refers to the vertical distance between the end surface of the free end of the positioning boss 204 and the side of the back plate 203 facing away from the filter body 100. During the tightening process, the sealing gasket 700 is compressed. Due to the limiting effect of the positioning boss 204, the thickness of the sealing gasket 700 is compressed to approximately 3 mm and then no longer compressed. This prevents local failure of the sealing gasket 700 due to excessive torque during tightening. The compressed EPDM sealing gasket 700 with a thickness of 3 mm can ensure an effective seal between the frame 200 and the vehicle body mounting plate 600.

[0049] In one embodiment, the filter body 100 and the frame 200 are connected by fasteners.

[0050] For maintenance-free filters, the filter body 100 and the frame 200 are connected by fasteners, which can ensure the connection firmness and water-proof performance between the filter body 100 and the frame 200. For example, the filter body 100 and the frame 200 are fixedly connected by fasteners such as bolts and nuts.

[0051] In one embodiment, the filter body 100 is hinged to the frame 200; the filter also includes a telescopic device 300, one end of the telescopic device 300 is hinged to the filter body 100, and the other end of the telescopic device 300 is hinged to the frame 200, so that the filter body 100 can rotate relative to the frame 200 around the axis of the hinge shaft between the filter body 100 and the frame 200.

[0052] For filters that require frequent maintenance and opening and closing, the filter body 100 is hinged to the frame 200, and the filter body 100 is opened via a telescopic device 300 for easy maintenance. For example, the telescopic device 300 can be a gas spring that automatically expands the filter body 100, creating an angle greater than 90° between the filter body 100 and the frame 200, facilitating maintenance of the filter body 100 and the in-vehicle equipment.

[0053] It should be noted that the telescopic device 300 is not limited to the above type. For example, the telescopic device 300 can also be a cylinder, a hydraulic cylinder or an electric push rod.

[0054] For example, see Figure 1 and Figure 2 As shown, the filter body 100 and the frame 200 are hinged via a hinge 400 . The hinge 400 may be an existing hidden hinge, thereby enhancing the aesthetics.

[0055] In one embodiment, see Figure 2 As shown, the filter further includes a locking device 500 , which is used to press and fix the filter body 100 to the frame 200 .

[0056] For example, the locking device 500 can be an existing mechanical locking device 500, as long as it can ensure that the filter body 100 and the frame 200 are locked, and that the first sealing member 102 can abut against the surface of the back plate 203 facing the filter body 100, and the second sealing member 202 can abut against the surface of the panel 103 facing the frame 200. For example, the locking device 500 is an existing ATS lock.

[0057] In one embodiment, the filter body 100 includes a louver and filter cotton, which is installed on the side of the louver facing the frame 200. The filter body has a comprehensive water blocking efficiency of not less than 90%. This method can effectively prevent large amounts of rainwater from entering the filter body 100, ensuring that the filtering performance of the filter body 100 is not damaged by rainwater.

[0058] This embodiment also provides a locomotive, including the filter provided by this embodiment.

[0059] The locomotive provided by this embodiment improves the sealing reliability between the locomotive side wall and the filter due to the use of the filter provided by this embodiment. When the locomotive is subjected to a rain test, a large amount of rainwater will enter the gap between the upper end of the filter and the side wall of the vehicle body. The rainwater will first fall on the first drain plate 101. Since a first seal 102 is provided between the first drain plate 101 and the frame 200, the first seal 102 can abut against the inner surface of the frame 200. When the first seal 102 has good sealing performance, the rainwater will be directly drained along the first drain plate 101. If the first seal 102 fails, the rainwater cannot be drained away from the first drain plate 101 in time, and some of the rainwater will enter the second drain plate 201. Since a second seal 202 is provided between the second drain plate 201 and the filter body 100, the second seal 202 can abut against the inner surface of the filter body 100, ensuring that the rainwater can be drained along the second drain plate 201. If the second sealing member 202 on the second drain plate 201 is well sealed, the overall seal of the filter will not fail.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
