Description

Technical Field

[0001] This utility model relates to a louver, and more particularly to a novel modular louver for the cooling chamber side of a locomotive. Background Technology

[0002] The side louvers of the locomotive cooling compartment are key components for regulating the airflow and ensuring heat dissipation efficiency. Existing side louvers in locomotive cooling compartments are mostly movable, consisting of upper and lower parts. The upper blades are pneumatically controlled, while the lower blades are mechanically driven to open and close. However, this design has significant drawbacks: First, the cylinder drive device and mechanical drive linkage mechanism are independent of the louver structure, requiring separate piping and connections, resulting in cumbersome assembly and space consumption. Second, the control mechanism is simplistic, relying heavily on automatic pneumatic control. In case of pneumatic failure, there is a lack of convenient and reliable manual emergency mechanisms, making it difficult to achieve emergency blade closure. Third, the structural reliability of maintaining the blades in the open state is insufficient; locomotive vibration and spring force decay can easily cause blade angle deviation, affecting airflow stability. Utility Model Content

[0003] The present invention aims to solve the above-mentioned defects and provide a novel modular louver for the cooling chamber side of a locomotive.

[0004] In order to overcome the defects in the background technology, the technical solution adopted by this utility model to solve its technical problem is: a new type of modular louver for the cooling chamber of a locomotive, including a window frame, on which a louver mechanism for opening and closing the blades to realize the opening and closing of the airflow channel is provided, an automatic execution mechanism for automatically triggering the action of the louver mechanism to close the blades, a manual mechanism for manually triggering the action of the louver mechanism to close the blades in an emergency, and an elastic connection mechanism for keeping the blades in the louver mechanism in an open state.

[0005] Further improvements include the use of a tension spring in the elastic connection mechanism, with the upper end of the tension spring connected to a connection point on the window frame and the lower end connected to the triggering component of the louver mechanism.

[0006] Further improvements include the automatic actuator comprising a cylinder and a matching pipeline connected to the cylinder, wherein a pneumatic damper is integrated on the cylinder.

[0007] Further improvements include the manual mechanism comprising a bending handle, a mounting plate, a guide tube, a movable connecting plate, a telescopic rod, and a safety lock pin.

One end of the bending handle is hinged to the hinge seat, and the bending point in the middle of the bending handle is hinged to one end of the movable connecting plate. The other end of the movable connecting plate is hinged to the top of the telescopic rod. The telescopic rod passes through the central hole of the guide tube, and a safety lock pin is radially inserted through the side wall of the guide tube. The safety lock pin is inserted into a corresponding lock hole on the telescopic rod.

[0008] Further improvements include the louver mechanism comprising blades, a sealing section, a pin, a lever, a connecting rod, and a connecting plate. The blades adopt a hollow cavity structure, and sealing sections are provided at both ends of the blades. A pin passes through the sealing sections coaxially. The two ends of the pin are installed in preset holes on the window frame of the window frame. A lever is provided on the sealing section on the same side of each blade. The free ends of all levers are rotatably connected to the same connecting rod. Multiple connecting plates are provided on the connecting rod.

[0009] Further improvements include the provision of asymmetrical hook-shaped portions on both sides of the blade.

[0010] Further improvements include providing grooves at both ends of the blade that are adapted to the shape of the closure portion, so that the closure portion is securely embedded in the grooves.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the scope of protection of this utility model.

[0015] refer to Figure 1 , Figure 2 and Figure 3 A novel modular louver for the cooling chamber side of a locomotive includes a window frame 4, which is equipped with a louver mechanism 3 for opening and closing blades 304 to achieve the opening and closing of the airflow channel, an automatic actuator 1 for automatically triggering the action of the louver mechanism 3 to close the blades 304, a manual mechanism 2 for manually triggering the action of the louver mechanism 3 to close the blades 304 in an emergency, and an elastic connection mechanism for keeping the blades 304 in the louver mechanism 3 in the open state.

[0016] When the manual mechanism 2 or the automatic actuator 1 is triggered downwards, the transmission structure inside the louver mechanism 3 is driven, causing the blades 304 in the louver mechanism 3 to close, thereby cutting off the airflow channel between the cooling chamber and the outside, and realizing the louver closing.

[0017] When the manual control mechanism 2 or the automatic actuator 1 returns to its initial state, the elastic connection mechanism releases the preload, and the transmission structure in the louver mechanism 3 is reset through elastic rebound, causing the blades 304 to flip to the open position, restoring the normal heat dissipation airflow channel of the cooling chamber.

[0018] For specific embodiments, please refer to Figure 1The elastic connection mechanism adopts a tension spring 5. The upper end of the tension spring 5 is connected to the connection point on the window frame 4, and the lower end is connected to the triggering component of the louver mechanism 3, so that the blade 304 in the louver mechanism 3 is kept in the open state. During assembly, the tension spring 5 is first in a pre-stretched state. Specifically, its upper hook is hooked on the bracket of the window frame 4, and its lower hook is connected to the hook on the connecting plate 302. The spring pulls the triggering component with continuous axial tension, so that the blade 302 rotates around the pin 301 to the open state and is maintained at the preset opening angle.

[0019] In a specific embodiment, the automatic actuator 1 is pneumatically driven, including a cylinder and a matching pipeline connected to the cylinder. To improve safety, a pneumatic damper is integrated into the cylinder. When the louvers are closing, the pneumatic damper precisely controls the extension and retraction speed of the cylinder piston rod by adjusting the airflow rate, so that the blades 304 close smoothly at a preset low speed, effectively avoiding the risk of pinching fingers that may occur due to excessively fast closing speed.

[0020] For specific embodiments, please refer to Figure 6 and Figure 5 The manual mechanism 2 is designed using the lever transmission principle and specifically includes a bending handle 205, a mounting plate 201, a guide cylinder 206, a movable connecting plate 202, a telescopic rod 207, and a safety lock pin 203. The mounting plate 201 serves as the basic load-bearing structure and is set at a predetermined position on the window frame 4. A hinge seat 204 and a guide cylinder 206 are mounted on the mounting plate, with the guide cylinder 206 arranged vertically. The bending handle 205 serves as the operating end, with one end hinged to the hinge seat 204. The bending point in the middle of the handle 205 is hinged to one end of the movable connecting plate 202, and the other end of the movable connecting plate 202 is hinged to the top of the telescopic rod 207, thereby forming a transmission structure that can rotate in multiple directions. The telescopic rod 207 passes through the central hole of the guide cylinder 206, and the central hole of the guide cylinder 206 provides a guide channel for the axial movement of the telescopic rod 207. The bottom end of the telescopic rod 207 corresponds to the triggering component of the louver mechanism 3. When the telescopic rod 207 moves downward along the axial direction, it triggers the action of the louver mechanism.

[0021] To ensure the stability of the mechanism in non-operational states, a safety locking pin 203 is radially inserted through the side wall of the guide cylinder 206. The safety locking pin 203 inserts into a corresponding locking hole 208 on the telescopic rod 207. Specifically, when the louvers are in the open or closed state, the safety locking pin 203 can be inserted into the corresponding locking hole 208 on the telescopic rod 207, mechanically limiting the telescopic rod 207 to maintain this state and preventing accidental closure due to accidental contact.

[0022] The manual operation process is as follows: When it is necessary to close the blinds, first pull out the safety lock pin 203 to release the limit on the telescopic rod 207, then turn the bending handle 205 downward. Through the rotation of the handle around the hinge seat 204, the force is transmitted to the telescopic rod 207 through the movable connecting plate 202, which drives the telescopic rod 207 to move smoothly downward along the center hole of the guide cylinder 206. When the telescopic rod 207 moves down to the preset stroke, its bottom end contacts the triggering component of the blind mechanism 3, and finally drives the blades 304 to close in an orderly manner according to the preset trajectory.

[0023] In a specific embodiment, refer to Figure 1 , Figure 3 and Figure 7 The louver mechanism 3 adopts a lightweight linkage design, including blades 304, sealing parts 306, pins 301, levers 307, connecting rods 303, and connecting plates 302. The blades 304 have a hollow cavity structure, with both ends sealed by the sealing parts 306 to form a complete unit. This significantly reduces the overall weight to decrease the driving load and improves heat and sound insulation performance through the internal cavity structure. The sealing parts 306 are coaxially connected by pins 301. The pins 301 are installed at pre-drilled holes in the window frame 4, allowing the blades 304 to... 04 can rotate flexibly around the pin 301 to form the basic opening and closing unit of the louver. In order to realize the synchronous action of multiple blades 304, each blade 304 is provided with a lever 307 on the same side of the closed part 306. The free ends of all levers 307 are rotatably connected to the same connecting rod 303. Multiple connecting plates 302 are provided on the connecting rod 303. These connecting plates 302 serve as triggering components and correspond to the telescopic rod 207 of the manual mechanism 2 and the cylinder output end of the automatic actuator 1, respectively. At the same time, connection points for the elastic connection mechanism are reserved.

[0024] Its working principle is as follows: When the telescopic rod 207 of the manual mechanism 2 moves down or the cylinder output end of the automatic actuator 1 is activated, it will directly push the corresponding connecting plate 302, and drive all levers 307 to swing synchronously through the connecting rod 303, so that the blades 304 rotate around the pin 301 to the closed position; when it is necessary to open the louvers, the elastic connecting mechanism pulls the connecting plate 302 to drive the connecting rod 303 to move in the opposite direction, so that the blades 304 return to the open state. At this time, the ventilation gap formed between the blades 304 can ensure air circulation and facilitate heat dissipation of equipment or space.

[0025] Further embodiments are described in reference to... Figure 4 The blades 304 have asymmetrical hook-shaped parts 305 on both sides. When the louvers are closed, the hook-shaped parts 305 of adjacent blades 304 will form a complementary hook-and-loop connection, forming a continuous sealing and interlocking structure, which further serves as a waterproof function.

[0026] Further embodiments are described in reference to... Figure 8 The blade 304 has grooves 308 at both ends that are adapted to the shape of the closure part 306, so that the closure part 306 is securely embedded in the grooves 308. This design enables the closure part 306 to be quickly positioned and installed, improves assembly efficiency, and enhances the overall structural strength of both.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
