Description

Technical Field

[0001] This invention relates to the field of traction locomotive technology, and in particular to a cooling mechanism and a traction locomotive. Background Technology

[0002] In the transmission system of a traction locomotive, heat dissipation is of paramount importance and is key to the reliable operation of the system. If the heat-generating modules cannot be cooled in time, they will be damaged. Therefore, a safe and reliable cooling system is the guarantee for the safe operation of the modules and the key to reducing the locomotive failure rate.

[0003] Currently, high-speed trains are traveling at increasingly higher speeds. During operation, wind barriers are formed at the cooling system's air outlets, affecting the cooling effect. Therefore, a portion of the cooling system's power must be used to overcome this resistance. In this situation, the fan requires greater power to ensure the cooling system's effectiveness, which increases the cooling system's energy consumption and installation space. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling mechanism and a traction locomotive to alleviate the problem in the prior art that, during high-speed train operation, wind barriers are formed at the air inlet and outlet of the cooling system, which increases the energy consumption of the cooling components and the installation space of the cooling system.

[0008] The drive unit is connected to the air intake grille assembly. The sensing control component is located in the mounting housing and is connected to the drive unit via a signal. When the sensing control component senses a change in the air intake direction and the temperature of the cooling component, it controls the drive unit to operate, thereby changing the opening and closing state of the air intake grille assembly.

[0009] As a further technical solution, the air intake grille assembly includes a grille support, a plurality of first grilles and a plurality of grille shafts, wherein the plurality of first grilles are distributed parallel to the edge of the air intake, and each first grille is connected to at least one grille shaft.

[0010] Multiple grid shafts are connected to the grid plate support for transmission, and the drive component is also connected to the grid plate support for transmission.

[0011] As a further technical solution, the first grid plate is fixedly connected to a grid shaft, which extends along the length of the first grid plate and is connected to the grid plate support in a driving manner.

[0012] As a further technical solution, the first grid plate is fixedly connected to two grid shafts, which are arranged parallel to each other along the width direction of the first grid plate and are both connected to the grid plate support in a driving manner.

[0013] As a further technical solution, the grid plate support includes a first support frame, a second support frame and multiple connecting rods. The first support frame and the second support frame are arranged in parallel and spaced apart. The multiple connecting rods are located between the first support frame and the second support frame, and their two ends are movably connected to the first support frame and the second support frame respectively. The driving component is connected to the first support frame or the second support frame in a transmission manner.

[0014] Of the two grid shafts connected to the same first grid sheet, one grid shaft is movably connected to the first support frame, and the other is movably connected to the second support frame.

[0015] As a further technical solution, the rotation angle of the first grid plate is 0° to 180°.

[0016] As a further technical solution, the sensing control component includes a direction sensor, a temperature sensor, and a controller. Both the direction sensor and the temperature sensor are signal-connected to the controller, and the controller is signal-connected to the drive unit.

[0017] As a further technical solution, the cooling assembly includes a cooling component and a fan. The fan is fixedly installed on the air outlet side, and the cooling component is fixedly installed inside the mounting housing and located between the fan and the air inlet grille assembly.

[0018] As a further technical solution, the cooling mechanism also includes a flow equalization grille assembly, which includes a plurality of second grille plates located between the cooling element and the air inlet grille assembly and distributed at intervals along the first direction.

[0019] As a further technical solution, the cooling mechanism also includes a filter element, which is detachably disposed within the mounting housing and located between the flow equalization grille assembly and the air intake grille assembly.

[0020] The traction locomotive provided by the present invention includes a cooling mechanism.

[0021] Compared with the prior art, the cooling mechanism and traction locomotive provided by the present invention have the following technical advantages:

[0022] The cooling mechanism provided by this invention, used in a traction locomotive, includes: an air intake grille assembly, a drive unit, a cooling assembly, a mounting housing, and a sensing control assembly. The mounting housing has an air inlet and an air outlet on its two side walls, respectively. The air intake grille assembly is movably disposed at the air inlet, and the cooling assembly is disposed within the mounting housing, positioned away from the air intake grille assembly. The drive unit is drive-connected to the air intake grille assembly. The sensing control assembly is disposed in the mounting housing and signal-connected to the drive unit. When the sensing control assembly senses changes in the air intake direction and the temperature of the medium at the cooling assembly outlet, it controls the drive unit to operate, thereby changing the opening / closing state of the air intake grille assembly. During locomotive operation, when the sensing control assembly senses changes in the air intake direction and the temperature of the cooling assembly, it receives sensing signals and controls the drive unit to operate based on these signals. This allows the opening / closing state of the air intake grille assembly to be changed according to the specific operating state of the locomotive, ensuring that the air intake grille assembly always provides effective natural airflow. Because the opening and closing state of the air intake grille assembly adaptively changes according to the specific driving conditions of the tractor, reducing or eliminating wind barriers formed at the air inlets and outlets, not only is there no need to increase the power of the cooling components, but the power of the fan can also be further reduced. This ensures the effectiveness of the cooling components while avoiding the problem of increased installation space. Furthermore, since the air inlet and outlet are located on the side wall and bottom of the mounting housing respectively, and the air intake grille assembly is movably positioned at the air inlet, with the cooling components opposite the air outlet, air entering the mounting housing from the air intake grille assembly can directly reach the cooling components, ensuring effective heat dissipation and further reducing energy consumption.

[0040] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] The cooling mechanism provided in this embodiment is used for traction locomotives and includes: an air intake grille assembly 100, a drive component, a cooling assembly 200, a mounting housing 300, and a sensing control assembly;

[0042] The two side walls of the mounting housing 300 are respectively provided with an air inlet and an air outlet. The air inlet grille assembly 100 is movably disposed at the air inlet, and the cooling assembly 200 is disposed inside the mounting housing 300 and disposed away from the air inlet grille assembly 100.

[0043] The drive unit is connected to the air intake grille assembly 100. The sensing control unit is located in the mounting housing 300 and is connected to the drive unit via a signal. When the sensing control unit senses a change in the air intake direction and the temperature of the cooling assembly 200, it controls the drive unit to operate, thereby changing the opening and closing state of the air intake grille assembly 100.

[0044] The cooling system is installed at the rear of the traction locomotive. The air inlet on the mounting shell 300 is located on the side wall of the traction locomotive, and the air outlet on the mounting shell 300 is located on the bottom wall of the traction locomotive. (Specific details to be added.) Figure 1As shown, during the locomotive's operation, when the sensing control component detects changes in the air intake direction and the temperature of the cooling component 200, it receives the sensing signal. Based on the received signal, it controls the drive component to operate, thereby changing the opening and closing state of the air intake grille assembly 100 according to the specific driving state of the locomotive, ensuring that the air intake grille assembly 100 is always in an effective natural air intake state. Because the opening and closing state of the air intake grille assembly 100 always adaptively changes according to the specific driving state of the locomotive, it will not form a wind barrier at the air intake. Therefore, there is no need to increase the power of the cooling component 200 to ensure the working effect of the cooling component 200, and it also avoids the problem of increasing the installation space of the cooling component 200. Furthermore, since the air inlet and air outlet are respectively located on two opposite side walls of the mounting housing 300, the air inlet grille assembly 100 is movably located at the air inlet, and the cooling assembly 200 is opposite to the air outlet, after the air enters the mounting housing 300 from the air inlet grille assembly 100, it can directly reach the cooling assembly 200, ensuring the heat dissipation effect of the cooling assembly 200 and further reducing the energy consumption of the cooling assembly 200.

[0045] In the optional technical solution of this embodiment, the air inlet grille assembly 100 includes a grille support 130, a plurality of first grille pieces 110 and a plurality of grille shafts 120. The plurality of first grille pieces 110 are distributed in parallel along the edge of the air inlet, and each first grille piece 110 is connected to at least one grille shaft 120.

[0046] Multiple grid shafts 120 are connected to the grid plate support 130 in a driving manner, and the driving component is connected to the grid plate support 130 in a driving manner.

[0047] In this embodiment, Figure 1 In the center, the direction from left to right is designated as the first direction. Specific combinations... Figures 1 to 5 As shown, along the first direction, multiple grille shafts 120 are rotatably mounted within the mounting housing 300. Each first grille plate 110 is connected to at least one grille shaft 120, and all grille shafts 120 are drive-connected to grille plate brackets 130, which are drive-connected to a driving component. When the driving component is activated, it drives the grille plate brackets 130 to move, thereby opening and closing the multiple first grille plates 110, introducing cooling air from outside the vehicle into the mounting housing 300, thus preventing wind obstruction at the air inlet. Furthermore, since each first grille plate 110 is connected to at least one grille shaft 120, the strength of the first grille plate 110 is increased, further improving the air intake effect. Additionally, the multiple first grille plates 110 can open or close simultaneously, or they can open or close individually. In this embodiment, to ensure the air intake effect, the multiple first grille plates 110 are configured to open or close simultaneously.

[0048] Regarding the arrangement of the first grid plate 110 and the grid shaft 120, the following two embodiments are provided:

[0049] In the first embodiment, in the optional technical solution of this embodiment, the first grid plate 110 is fixedly connected to a grid shaft 120, the grid shaft 120 extends along the length direction of the first grid plate 110 and is rotatably connected to the grid plate support 130.

[0050] Specific combination Figure 5 As shown, the first grid plate 110 is fixedly connected to a grid shaft 120. In this embodiment, the grid shaft 120 is positioned corresponding to the centerline of the first grid plate 110 and is connected to the grid plate support 130. The grid plate support 130 and the driving component can be configured as follows: the grid plate support 130 is a double-sided rack, and the connection ends of multiple grid shafts 120 and the grid plate support 130 are each provided with a first gear corresponding to the first surface of the double-sided rack. The first surface of the double-sided rack meshes with the first gear. The driving component is a rotary motor, and a second gear adapted to the second surface of the double-sided rack is fixedly mounted on the motor shaft of the rotary motor. The second surface of the double-sided rack meshes with the second gear. As the rotary motor starts, the motor shaft drives the second gear to rotate, and the second gear meshes with the second surface of the double-sided rack. The first surface of the double-sided rack simultaneously meshes with multiple first gears, thereby driving multiple grid shafts 120 to rotate, thus realizing the unified opening or closing of multiple first grid plates 110. The above-mentioned setting method is gear and rack transmission. It can also be set to chain transmission, pulley transmission or linkage transmission, etc. The specific setting method is set according to specific needs, as long as it can achieve the technical purpose of multiple first grid pieces 110 moving in the same direction.

[0051] In the second embodiment, the first grid plate 110 is fixedly connected to two grid shafts 120. The two grid shafts 120 are arranged parallel to each other along the width direction of the first grid plate 110 and are both connected to the grid plate support 130 in a transmission manner.

[0052] Specific combination Figures 2 to 4 As shown, each first grid plate 110 is fixedly provided with two grid shafts 120. The two grid shafts 120 are arranged parallel to each other along the width direction of the first grid plate 110 and are symmetrically arranged about the center line of the first grid plate 110. They are also connected to the grid plate support 130 for transmission. The arrangement of the grid plate support 130 and the driving component is the same as that in the first embodiment described above. The fixed connection between the first grid plate 110 and the two grid shafts 120 further enhances the strength of the first grid plate 110. Moreover, since the two grid shafts 120 are symmetrically arranged about the center line of the first grid plate 110, the flexibility of the first grid plate 110 when opening or closing can be improved.

[0053] In the optional technical solution of this embodiment, the grid plate support 130 includes a first support frame 131, a second support frame 132 and multiple connecting rods 133. The first support frame 131 and the second support frame 132 are arranged in parallel and spaced apart. The multiple connecting rods 133 are located between the first support frame 131 and the second support frame 132, and their two ends are movably connected to the first support frame 131 and the second support frame 132 respectively. The driving member is transmittedly connected to the first support frame 131 or the second support frame 132.

[0054] Of the two grid shafts 120 connected to the same first grid plate 110, one grid shaft 120 is movably connected to the first support frame 131, and the other is movably connected to the second support frame 132.

[0055] Specific combination Figure 4 As shown, AC and BD are two grid shafts 120, which cooperate with connecting rods AB and CD to form a first support frame 131; ac and bd are two grid shafts 120, which cooperate with connecting rods ab and cd to form a second support frame 132. Connecting the first support frame 131 and the second support frame 132 is a connecting rod 133, as shown... Figure 1 In this design, Aa, Bb, Cc, and Dd are all connecting rods 133. The number of connecting rods 133 can be increased or decreased appropriately to achieve the effect of transmission between the first support frame 131 and the second support frame 132. The first support frame 131 and the second support frame 132 can rotate along any grid axis 120 among AC, BD, ac, and bd, thereby realizing the opening or closing of multiple first grid pieces 110.

[0056] During assembly, taking the installation of the first grid piece 110 on the two grid shafts 120 (AC and BD) as an example, the two grid shafts 120 are fixedly connected to the first grid piece 110 respectively, completing the installation of one first grid piece 110. The other first grid pieces 110 are set up according to the same steps. In addition, when multiple first grid pieces 110 are opened or closed, the first support frame 131 can be set to remain stationary, the second support frame 132 can be set to remain stationary, or both the first support frame 131 and the second support frame 132 can be set to move. The specific setting method can be selected according to specific needs, as long as the technical purpose of multiple first grid pieces 110 moving in unison is achieved.

[0057] In this embodiment, the rotation angle of the first grid plate 110 is 0° to 180°.

[0058] Specific combination Figures 1 to 5As shown, since each first grid plate 110 can rotate 180°, the rotation angle can be changed according to the different forward directions of the traction locomotive, thereby ensuring the air intake and cooling effects. In addition, in this embodiment, the first grid plate 110 can be set as a straight blade, an arc blade, a bent blade, or an airfoil-shaped blade, etc., and the shape of the first grid plate 110 can be changed according to the working environment of the traction locomotive.

[0059] In the optional technical solution of this embodiment, the sensing control component includes a direction sensor, an air volume sensor, and a controller. The direction sensor and the temperature sensor are both signal-connected to the controller, and the controller is signal-connected to the drive component.

[0060] Specifically, during the locomotive's operation, the direction sensor detects the driving direction, and the temperature sensor detects the temperature of the cooling assembly 200. Both transmit their signals to the controller, which receives the signals and controls the opening and closing of the air intake grille assembly 100 to ensure that the air intake grille assembly 100 is always in an effective natural air intake state. This configuration allows the cooling mechanism to adaptively adjust the air intake grille assembly 100 according to the locomotive's driving state, thereby ensuring the working effect of the cooling assembly 200 and avoiding the problem of increased installation space for the cooling assembly 200.

[0061] In the optional technical solution of this embodiment, the cooling component 200 includes a cooling element 210 and a fan 220. The fan 220 is fixedly installed at the air outlet, and the cooling element 210 is fixedly installed inside the mounting housing 300 and located between the fan 220 and the air inlet grille assembly 100.

[0062] Specific combinations and Figure 1 As shown, airflow cools the cooling component 210, fan 220 assists in heat dissipation of the cooling component 210, and temperature sensor senses the temperature of the medium at the outlet of the cooling component 210. Specifically, when the locomotive is traveling at low speed, fan 220 starts to dissipate heat from the cooling component 210; in this state, heat dissipation of the cooling component 210 is the primary function, with airflow cooling as a secondary function. When the locomotive is traveling at high speed, airflow cooling is the primary function, with fan 220 starting to dissipate heat from the cooling component 210 as a secondary function. In this embodiment, the temperature sensor is used to sense the temperature of the heat medium in the cooling component 210.

[0063] In the optional technical solution of this embodiment, the cooling mechanism further includes a flow equalization grid assembly 400, which includes a plurality of second grid plates located between the cooling component 210 and the air inlet grid assembly 100 and distributed at intervals along the first direction.

[0064] Specific combination Figure 1As shown, multiple second grille plates are fixedly installed inside the mounting housing 300 and evenly spaced along the first direction. These second grille plates are located between the cooling element 210 and the air inlet grille assembly 100. This arrangement allows the multiple second grille plates to adjust the airflow entering the mounting housing 300 from the air inlet, ensuring uniform airflow through the cooling element 210 and further improving its heat dissipation effect. Furthermore, in this embodiment, the length of each second grille plate is set to be greater than or equal to the distance between two adjacent second grille plates.

[0065] In the optional technical solution of this embodiment, the cooling mechanism further includes a filter element 500, which is detachably disposed in the mounting housing 300 and located between the flow equalization grille assembly 400 and the air inlet grille assembly 100.

[0066] Specific combination Figure 1 As shown, the filter element 500 can be configured as a screen or filter cloth, and the mesh size of the screen or filter cloth can be changed according to the working environment of the tractor. In this embodiment, the filter element 500 is configured as a screen. During operation, the screen prevents foreign objects from entering the cooling mechanism, reducing the impact of foreign objects on the cooling component 200, thereby ensuring the working effect of the cooling mechanism and extending its service life.

[0067] In addition, in this embodiment, the filter element 500, the flow equalization grille assembly 400 and the air inlet grille assembly 100 can all be detachably installed in the mounting housing 300, ensuring their respective performance while facilitating maintenance and cleaning.

[0068] When the air inlet of the mounting housing 300 is not equipped with the air inlet grille assembly 100, the fan 220 operates to eliminate the wind obstruction formed at the air inlet and outlet. When the air inlet of the mounting housing 300 is equipped with the air inlet grille assembly 100, the air inlet grille assembly 100 cooperates with the fan 220 to eliminate the wind obstruction formed at the air inlet and outlet. In addition, this embodiment provides a cooling mechanism that, in addition to providing the air inlet grille assembly 100 at the air inlet of the mounting housing 300, can also provide the air inlet grille assembly 100 at the air outlet of the mounting housing 300. The structure and working principle of the air inlet grille assembly 100 provided at the air outlet are set with reference to the structure and working principle of the air inlet grille assembly 100 provided at the air inlet.

[0069] The locomotive provided in this embodiment includes a cooling mechanism. Since the locomotive includes all the structures of the cooling mechanism, the locomotive provided in this embodiment possesses all the beneficial effects of the aforementioned cooling mechanism.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions 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 invention.
