Description

Technical Field

[0001] This utility model relates to the field of internal combustion locomotive equipment technology, specifically to an exhaust louver for internal combustion locomotives. Background Technology

[0002] The original ventilation louvers had fixed blades. Although adjusting the angle and spacing between the blades could prevent most water from entering, rainwater would still inevitably splash into the room. Other ventilation louvers had blades that could be adjusted manually or pneumatically, but these required manual opening and closing. These types of ventilation louvers also could not prevent rainwater from splashing into the room.

[0003] Publication number CN109484141A discloses an exhaust louver for an internal combustion engine, consisting of an outer window frame and a duct. The duct is welded to the vehicle body, and the outer window frame is bolted to the duct. Mounting seats are provided at corresponding positions on the outer window frame and the duct. The outer window frame is freely detachable, facilitating the maintenance and replacement of the louvers. However, this patent still has the following problems in practical use:

[0004] The system consists of an outer window frame and a duct. The duct is welded to the vehicle body, and the outer window frame is bolted to the duct. Mounting seats are provided at corresponding positions on the outer window frame and the duct. The outer window frame can be freely disassembled for easy maintenance and replacement of the blades. However, the blades automatically open when they encounter exhaust air pressure, which leads to frequent opening and closing of the blades. The closing of the blades causes them to collide with each other. The frequent use of the blades over a long period of time will increase the number of impacts they are subjected to. Even if each impact is minor, long-term accumulation may lead to fatigue damage, which to some extent increases costs and reduces the service life of the blades.

[0005] An exhaust louver for internal combustion locomotives is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an exhaust louver for internal combustion locomotives, to solve the problems mentioned in the background art. The current system consists of an outer window frame and a duct, with the duct welded to the vehicle body and the outer window frame bolted to it. The outer window frame and duct have mounting seats at corresponding positions, and the outer window frame is freely detachable for easy maintenance and replacement of the blades. However, in this system, the blades automatically open when exposed to exhaust pressure, leading to frequent opening and closing. The closing of the blades causes collisions between them, and prolonged use increases the number of impacts they endure. Even minor impacts can accumulate over time, potentially causing fatigue damage and increasing costs while reducing the lifespan of the blades.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an exhaust louver for an internal combustion locomotive, comprising a base plate, wherein mounting seats are fixedly installed around the perimeter of the base plate;

[0008] The base plate is symmetrically fitted with an outer frame, and a connecting rod is fitted inside the outer frame. A fan blade is connected through the surface of the connecting rod. Grooves are symmetrically opened on both sides inside the connecting rod. A fixing rod is fixedly installed inside the groove. A compression spring is sleeved on the surface of the fixing rod. One side of the compression spring is fixedly connected to the groove.

[0009] Also includes:

[0010] A placement groove is provided on the inner side of the fan blade near the top, and a buffer component is provided inside the placement groove;

[0011] The buffer assembly includes a fixing plate that is fixedly connected to the placement slot;

[0012] Among them, the fixing plate has symmetrically installed barrier blocks on the side surface away from the placement groove.

[0013] Preferably, a telescopic rod is fixedly connected to the bottom surface of the barrier block, a return spring is sleeved on the surface of the telescopic rod, a fixing block is fixedly connected to the bottom surface of the return spring, and the top surface of the return spring is fixedly connected to the barrier block.

[0014] Preferably, the fixing block is attached to the fixing plate, a slider is fixedly connected to the middle of one side surface of the fixing block, and the fixing plate has symmetrical sliding grooves on the side surface away from the placement groove, and the sliding grooves are slidably connected to the slider.

[0015] Preferably, a stabilizing block is fixedly connected to the middle of the side surface of the fixed block away from the slider, and a movable rod is rotatably connected to the middle of the side surface of the stabilizing block away from the fixed block.

[0016] Preferably, a support block is rotatably connected to the side surface of the movable rod away from the stabilizing block, and a buffer plate is fixedly connected to the side surface of the support block away from the movable rod.

[0017] Preferably, an extension rod is fixedly connected to the other side surface of the compression spring, the extension rod has a movable groove inside, the movable groove is sleeved and connected to the fixed rod, and the extension rod is connected through the outer frame.

[0018] Preferably, a cotter pin is connected through the surface of the extension rod away from the outer frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This exhaust louver for internal combustion locomotives, by setting a buffer component, reduces the impact force between the blades, thereby extending the service life of the blades to a certain extent. Simultaneously, by setting a connecting rod, groove, fixing rod, compression spring, extension rod, moving slot, and cotter pin, it effectively prevents the connecting rod and blades from falling off. Furthermore, it makes disassembly and replacement of the blades more convenient. The specific details are as follows:

[0020] 1. By setting up a buffer assembly, when the fan blades are not subjected to exhaust air pressure, the fan blades will close due to their own gravity. When the fan blades close, they will impact the buffer plate, causing the buffer plate to move under force. This movement of the buffer plate will cause the support block to descend, which in turn will cause the movable rod to descend. The descent of the movable rod will push the fixed block to move, causing the fixed blocks on both sides to move to the sides. This movement of the fixed blocks will compress the telescopic rod and the return spring, causing the return spring to deform. Through the cooperation between the return spring and the telescopic rod, the impact force is buffered, thus buffering the blades and effectively reducing the impact force between the blades, thereby extending the service life of the fan blades to a certain extent.

[0021] 2. By incorporating a connecting rod, groove, fixing rod, compression spring, extension rod, moving slot, and cotter pin, when the fan blades need to be disassembled, the cotter pin is separated from the pin hole on the extension rod, and the extension rod is pressed with a tool, causing it to move. This movement of the extension rod compresses the compression spring, causing it to deform. Once the extension rod reaches a certain position, it separates from the hole on the outer frame, allowing the connecting rod and fan blades to be removed. When installing the fan blades, the connecting rod is moved to the appropriate position, aligning the extension rod with the hole on the outer frame. The extension rod then returns to its original position under the action of the compression spring, allowing it to pass through the hole. Inserting the cotter pin into the pin hole prevents the connecting rod and fan blades from falling off. The fan blades and connecting rod are connected by a through-rotation mechanism, allowing the fan blades to rotate during exhaust, thus achieving the opening function. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: an exhaust louver for an internal combustion engine, including a base plate 1, with mounting seats 2 fixedly installed around the base plate 1; an outer frame 3 symmetrically installed on the surface of the base plate 1, a connecting rod 4 fitted inside the outer frame 3, a fan blade 5 penetrating the surface of the connecting rod 4, grooves 6 symmetrically opened on both sides of the inside of the connecting rod 4, a fixing rod 7 fixedly installed inside the groove 6, a compression spring 8 sleeved on the surface of the fixing rod 7, and one side surface of the compression spring 8 fixedly connected to the groove 6; it also includes: a placement groove 12 opened on the inner side of the fan blade 5 near the top, and a buffer assembly 13 disposed inside the placement groove 12; wherein, the buffer assembly 13 includes a fixing plate 1301 fixedly connected to the placement groove 12; wherein, a blocking block 1302 is symmetrically installed on the side surface of the fixing plate 1301 away from the placement groove 12, such as Figure 1-5As shown, by setting the buffer component 13, the impact force between the fan blades 5 is reduced, which can improve the service life of the fan blades 5 to a certain extent. At the same time, by setting the connecting rod 4, groove 6, fixing rod 7, compression spring, extension rod 9, moving groove 10 and cotter pin 11, the connecting rod 4 and fan blades 5 can be effectively prevented from falling off. At the same time, it is also more convenient to disassemble and replace the fan blades 5.

[0030] A telescopic rod 1303 is fixedly connected to the bottom surface of the barrier block 1302. A return spring 1304 is sleeved on the surface of the telescopic rod 1303. A fixing block 1305 is fixedly connected to the bottom surface of the return spring 1304. The top surface of the return spring 1304 is fixedly connected to the barrier block 1302. The fixing block 1305 is in close contact with the fixing plate 1301. A slider 1306 is fixedly connected to the middle of one side surface of the fixing block 1305. The side surface of the fixing plate 1301 away from the placement groove 12 is symmetrically opened. A slide groove 1307 is provided, which is slidably connected to a slider 1306. A stabilizing block 1308 is fixedly connected to the middle of the surface of a fixed block 1305 away from the slider 1306. A movable rod 1309 is rotatably connected to the middle of the surface of the stabilizing block 1308 away from the fixed block 1305. A support block 1310 is rotatably connected to the surface of the movable rod 1309 away from the stabilizing block 1308. A buffer plate 1311 is fixedly connected to the surface of the support block 1310 away from the movable rod 1309. Figure 3 , 4 As shown, the movement of the buffer plate 1311 causes the support block 1310 to descend. The descent of the support block 1310 causes the movable rod 1309 to descend. Simultaneously, the descent of the movable rod 1309 pushes the fixed block 1305 to move, causing the fixed blocks 1305 on both sides to move to the sides. The movement of the fixed blocks 1305 compresses the telescopic rod 1303 and the return spring 1304, causing the return spring 1304 to deform. Through the cooperation between the return spring 1304 and the telescopic rod 1303, the impact force is buffered, thereby buffering the blades and effectively reducing the impact force between the blades, thus extending the service life of the fan blades 5 to a certain extent.

[0031] An extension rod 9 is fixedly connected to the other side surface of the compression spring 8. A movable groove 10 is provided inside the extension rod 9, and the movable groove 10 is sleeved and connected to the fixed rod 7. The extension rod 9 is connected through the outer frame 3, and a cotter pin 11 is connected through the side surface of the extension rod 9 away from the outer frame 3. Figure 1 , 2As shown in Figure 5, when installing the fan blade 5, after moving the connecting rod 4 to the appropriate position, the extension rod 9 is aligned with the hole on the outer frame 3. The extension rod 9 then returns to its original position under the action of the compression spring 8, so that the extension rod 9 passes through the hole. At the same time, by inserting the cotter pin 11 into the pin hole, the connecting rod 4 and the fan blade 5 can be prevented from falling off. Since the fan blade 5 and the connecting rod 4 are connected by a through-rotation connection, the fan blade 5 can rotate during exhaust, thereby achieving the function of opening.

[0032] Working principle: Before using this type of exhaust louver for internal combustion locomotives, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5 As shown, by first setting the buffer assembly 13, when the fan blade 5 is not subjected to exhaust wind pressure, the fan blade 5 will close due to its own gravity. When the fan blade 5 closes, it will impact the buffer plate 1311, causing the buffer plate 1311 to move under force. The movement of the buffer plate 1311 will cause the support block 1310 to descend. The descent of the support block 1310 will cause the movable rod 1309 to descend. At the same time, the descent of the movable rod 1309 will push... The movement of the fixing block 1305 causes the fixing blocks 1305 on both sides to move to the sides. At the same time, the movement of the fixing block 1305 will compress the telescopic rod 1303 and the return spring 1304, causing the return spring 1304 to deform. Through the cooperation between the return spring 1304 and the telescopic rod 1303, the impact force is buffered, thereby buffering the blades and effectively reducing the impact force between the blades, which can improve the service life of the fan blades 5 to a certain extent.

[0033] Secondly, by setting up connecting rod 4, groove 6, fixing rod 7, compression spring, extension rod 9, moving groove 10, and cotter pin 11, when it is necessary to disassemble the fan blade 5, after separating the cotter pin 11 from the pin hole on the extension rod 9, the extension rod 9 is pressed with a tool, thereby causing the extension rod 9 to move. At the same time, the movement of the extension rod 9 will compress the compression spring 8, causing the compression spring 8 to deform. After the extension rod 9 moves to a certain position, it separates from the hole on the outer frame 3, thereby allowing the connecting rod 5 to be disassembled. The connecting rod 4 and the fan blade 5 are disassembled. When installing the fan blade 5, the connecting rod 4 is moved to a suitable position so that the extension rod 9 is aligned with the hole on the outer frame 3. The extension rod 9 then returns to its original position under the action of the compression spring 8, so that the extension rod 9 passes through the hole. At the same time, by inserting the cotter pin 11 into the pin hole, the connecting rod 4 and the fan blade 5 can be prevented from falling off. The fan blade 5 and the connecting rod 4 are connected by a through-rotation connection, which allows the fan blade 5 to rotate during exhaust, thereby achieving the function of opening.
