Description

Technical Field

[0001] The utility model relates to the technical field of AC locomotives, and more specifically, to a self-cleaning filter for locomotive cooling towers. Background Technique

[0002] The roof ventilation system of an AC locomotive is a key part to ensure the normal operation of the locomotive cooling system. The structure and materials used in this system are crucial for the filtering effect and directly affect the cooling performance of the cooling tower. The main function of the cooling tower is to cool the main transformer and the main converter, which are essential for the stable operation of the locomotive. If the roof ventilation system is blocked by foreign objects or dust, it will seriously affect the cooling effect, causing the main electrical equipment to overheat due to insufficient cooling, thus bringing significant safety risks. However, after long-term use of the existing self-cleaning filter for locomotive cooling towers, if it breaks down, it needs to be removed as a whole, which is not convenient for replacing the filter screen alone, thereby reducing the replacement efficiency.

[0003] For example, Chinese Patent CN218166280U discloses a roof filter for an AC locomotive cooling tower, including a mounting base. A ventilation opening is provided at the top of the mounting base, and a semi-circular filter screen is arranged on the top of the mounting base and located above the ventilation opening.

[0004] The roof filter for the AC locomotive cooling tower has the following disadvantages: Although the air entering the ventilation opening is filtered by the semi-circular filter screen, the filtering area is increased, and sufficient ventilation volume is ensured. At the same time, catkins and other sundries are not easily adsorbed on the semi-circular surface and are easy to clean. However, after long-term use, if it breaks down, it needs to be removed as a whole, which is not convenient for replacing the filter screen alone, thereby reducing the replacement efficiency.

[0005] Regarding the problems in the related technology, no effective solution has been proposed yet. Summary of the Utility Model

[0006] Regarding the problems in the related technology, the utility model proposes a self-cleaning filter for locomotive cooling towers to overcome the above-mentioned technical problems existing in the existing related technology.

[0007] To this end, the specific technical solution adopted by the utility model is as follows:

[0008] The self-cleaning filter for locomotive cooling towers includes a mounting base. A plurality of ventilation openings are provided at the top end of the mounting base. Arc-shaped filter screens are arranged in cooperation with the tops of the ventilation openings. Two groups of limiting holes one are symmetrically provided on the inner walls of the ventilation openings, and limiting components matched with the arc-shaped filter screens are arranged inside the limiting holes one.

[0009] Further, in order to limit the arc-shaped filter screen under the action of the limit chute, so as to avoid the phenomenon of deviation when the arc-shaped filter screen is replaced, the installation base includes limit chutes symmetrically arranged on both sides of the top of the ventilation opening, and the limit chutes are matched with the arc-shaped filter screen. Limit sliding plates matched with the limit chutes are symmetrically arranged on both sides of the bottom of the arc-shaped filter screen. Limit holes two matched with the first limit holes are symmetrically arranged at both ends of one side of the limit sliding plate. The cross section of the limit sliding plate is set as an L-shaped structure.

[0010] Further, in order to quickly install and disassemble a single arc-shaped filter screen under the action of the limit component, thereby improving the replacement efficiency of the self-cleaning filter of the locomotive cooling tower and avoiding the occurrence of the phenomenon of overall disassembly and reduced replacement efficiency, the limit component includes an outer sleeve arranged on one side of the first limit hole. A cavity is provided inside the outer sleeve. A limit post is sleeved inside the cavity. A pull ring is arranged on one side of the limit post. The other side of the limit post passes through the limit sliding plate and is cooperatively arranged inside the second limit hole. A spring is sleeved on the circumferential outer wall of the limit post. A limit disc is arranged on one side of the spring. One side of the limit disc is matched with the inner bottom end of the cavity, and the limit disc is sleeved on the circumferential outer wall of the limit post.

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

[0012] 1. The structure of the present utility model is reasonable and reliable, and the operation is simple. During the running of the locomotive, the wind enters the ventilation opening through the arc-shaped filter screen. Under the action of the arc-shaped filter screen, the dust in the wind can be filtered, and the ventilation volume can be increased, making the cooling tower have a larger air volume and a better cooling effect. And the arc-shaped filter screen is installed clockwise, so that some fallen leaves and sundries can be naturally carried away by the wind during the running of the locomotive. At the same time, under the action of the limit component, a single arc-shaped filter screen can be quickly installed and disassembled, thereby improving the replacement efficiency of the self-cleaning filter of the locomotive cooling tower and avoiding the occurrence of the phenomenon of overall disassembly and reduced replacement efficiency.

[0013] 2. By arranging the limit chute and the limit sliding plate, the arc-shaped filter screen can be limited, and the arc-shaped filter screen can slide in the limit chute, avoiding the phenomenon of deviation when the arc-shaped filter screen is replaced, thereby improving the work efficiency.

[0014] 3. By setting a limit assembly, when the arc filter needs to be replaced, by pulling the pull ring outward, the limit column is driven to move outward. At this time, the limit plate compression spring moves outward, so that the end of the limit column is disengaged from the inside of the limit hole 2, thereby taking the arc filter that needs to be replaced out of the limit slide groove for replacement and maintenance. When the arc filter needs to be installed, the arc filter is placed into the limit slide groove through the limit slide plate for movement. When the limit hole 1 coincides with the limit hole 2, the pull ring is released. Under the action of the spring rebound force, the limit plate moves inward, which drives the limit column to move inward, so that the end of the limit column is stuck in the limit hole 2. At this time, the arc filter can be installed and fixed, thereby improving the replacement efficiency of the self-dust removal filter of the locomotive cooling tower, avoiding overall dismantling and reducing the replacement efficiency.

[0025] To further illustrate each embodiment, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. They are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operation principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a self-cleaning filter for a locomotive cooling tower is provided.

[0027] Now, the present invention will be further described in conjunction with the accompanying drawings and the detailed implementation mode. As Figures 1-7 shown, the self-cleaning filter for a locomotive cooling tower according to an embodiment of the present invention includes an installation base 1. A plurality of vents 2 are opened at the top of the installation base 1. Arc-shaped filter screens 3 are respectively arranged at the tops of the vents 2 in a matching manner. Two groups of first limit holes 4 are symmetrically opened on the inner walls of the vents 2. Limit assemblies 5 that cooperate with the arc-shaped filter screens 3 are arranged inside the first limit holes 4. The installation base 1 includes limit chutes 101 that are symmetrically arranged on both sides at the top of the vent 2, and the limit chutes 101 cooperate with the arc-shaped filter screens 3. Limit slide plates 301 that cooperate with the limit chutes 101 are symmetrically arranged at both sides of the bottom of the arc-shaped filter screen 3. Second limit holes 302 that cooperate with the first limit holes 4 are symmetrically opened at both ends of one side of the limit slide plate 301. The cross-section of the limit slide plate 301 is arranged in an L-shaped structure.

[0028] In one embodiment, for the above-mentioned limiting component 5, the limiting component 5 includes an outer sleeve 501 disposed on one side of the first limiting hole 4. In specific applications, one side wall of the outer sleeve 501 is fixedly connected to the inner wall of the ventilation opening 2. A cavity 502 is formed inside the outer sleeve 501. A limiting post 503 is sleeved inside the cavity 502. A pull ring 504 is disposed on one side of the limiting post 503. The other side of the limiting post 503 penetrates through the limiting slide plate 301 and is cooperatively disposed inside the second limiting hole 302. A spring 505 is sleeved on the circumferential outer wall of the limiting post 503. A limiting disc 506 is disposed on one side of the spring 505. One side of the limiting disc 506 is cooperatively disposed with the inner bottom end of the cavity 502, and the limiting disc 506 is sleeved on the circumferential outer wall of the limiting post 503. Thus, under the action of the limiting component 5, the single arc-shaped filter screen 3 can be quickly installed and disassembled, thereby improving the replacement efficiency of the self-cleaning filter of the locomotive cooling tower and avoiding the occurrence of the phenomenon of overall disassembly and reduction of the replacement efficiency.

[0029] The specific working principle of the limiting component 5 is as follows: When the arc-shaped filter screen 3 needs to be replaced, by pulling the pull ring 504 outward, the limiting post 503 is driven to move outward. At this time, the limiting disc 506 compresses the spring 505 and moves outward, so that the end of the limiting post 503 is disengaged from the inside of the second limiting hole 302, and thus the arc-shaped filter screen 3 to be replaced can be taken out from the limiting chute 101 for replacement and maintenance. When the arc-shaped filter screen 3 needs to be installed, the arc-shaped filter screen 3 is placed into the limiting chute 101 through the limiting slide plate 301 and moved. When the first limiting hole 4 coincides with the second limiting hole 302, the pull ring 504 is released. Under the action of the resilience of the spring 505, the limiting disc 506 moves inward, driving the limiting post 503 to move inward, so that the end of the limiting post 503 is clamped inside the second limiting hole 302. At this time, the arc-shaped filter screen 3 can be installed and fixed, thereby improving the replacement efficiency of the self-cleaning filter of the locomotive cooling tower and avoiding the occurrence of the phenomenon of overall disassembly and reduction of the replacement efficiency.

[0030] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0031] In actual application, the self-cleaning filter of the locomotive cooling tower is installed on the top of the locomotive cooling tower through the mounting base 1. Then, when the locomotive is running, the outside air enters the ventilation port 2 through the arc-shaped filter screen 3, and then enters the inside of the cooling tower through the ventilation port 2 for cooling. Under the action of the arc-shaped filter screen 3, the dust in the air is filtered and blocked, preventing the dust from entering the inside of the cooling tower. When one or more arc-shaped filter screens 3 need to be replaced, the arc-shaped filter screen 3 can be conveniently installed and disassembled through the limiting component 5, avoiding overall disassembly and reducing the occurrence of the phenomenon of reducing the replacement efficiency. And under the action of the arc-shaped filter screen 3, the ventilation volume can be increased, the air volume of the cooling tower can be increased, and a better cooling effect can be achieved. And the arc-shaped filter screen 3 is installed clockwise (in specific application, the installation direction of the arc-shaped filter screen 3 is parallel to the driving direction of the locomotive, so that the air flows through the arc-shaped filter screen 3 along the driving direction of the locomotive, thereby enhancing the consistency of air flow and reducing resistance, which helps to more effectively capture and isolate the particles and dust in the air), so that some fallen leaves and sundries can be naturally carried away by the wind during the running of the locomotive.

[0032] In summary, by means of the above technical solution of the present invention, through the setting of the limiting chute 101 and the limiting slide plate 301, the arc-shaped filter screen 3 can be limited, and the arc-shaped filter screen 3 can slide in the limiting chute 101, avoiding the phenomenon of deviation when the arc-shaped filter screen 3 is replaced, thereby improving the work efficiency. By setting the limiting component 5, under the action of the limiting component 5, the single arc-shaped filter screen 3 can be quickly installed and disassembled, thereby improving the replacement efficiency of the self-cleaning filter of the locomotive cooling tower, avoiding overall disassembly and reducing the occurrence of the phenomenon of reducing the replacement efficiency.
