Description

[0001] The present application relates to the field of locomotive motor heat dissipation, more particularly, it relates to a locomotive integrated cooling system. BACKGROUND

[0002] The locomotive integration refers to the integration of electric power source and internal combustion power source in a locomotive, which can not only run on electrified lines by electric traction to realize road network penetration, but also provide power by internal combustion engine to realize traction in non-electrified lines or special situations such as contact net failure.

[0003] At present, the existing locomotive integrated cooling system has the following technical problems in the ventilation cooling of the locomotive motor in the locomotive:

[0004] The existing locomotive integrated cooling system simply cools the locomotive motor in the working process by air ventilation, which results in low heat conduction efficiency of the heat generated by the locomotive motor in the air, reduces the heat dissipation efficiency of the locomotive motor in the working process, and affects the use of the locomotive motor. SUMMARY

A circular hole is provided through the center of the rectangular aerodynamic plate, and a bearing is installed in the circular hole. The rotating column passes through the inner ring of the bearing and rotates with it.

[0011] The present invention is further configured such that guide grooves are provided on both opposite sides of several of the mounting ports.

[0012] The heat-conducting component includes an arc-shaped heat-absorbing plate that slides onto the mounting port, and a number of heat dissipation fins are fixed on the outer wall of the arc-shaped heat-absorbing plate.

[0013] The present invention is further configured such that: each of the several heat dissipation fins has a sliding block fixed on both sides, and the two sliding blocks are respectively slidably engaged with the two guide grooves.

[0014] A sliding block has a slide plate fixed to its bottom. The top of the slide plate has a guide hole that slides through and engages with a guide rod. The bottom of the slide plate has an extension rod that slides with a rectangular spoiler. The bottom of the extension rod is spherical. The end of the elastic spring is fixedly connected to the bottom of the slide plate.

[0015] The invention is further configured such that: a dual-axis motor is fixed on the side of the cross plate outside the cover cylinder, and one output shaft of the dual-axis motor is fixedly connected to the center position of the rotating disk.

[0016] A ventilation fan is fixed to the other output shaft of the dual-axis motor.

[0017] The present invention is further configured such that a first connecting flange is fixed at the end of the cover near the cross plate.

[0018] The cover component includes a second connecting flange that is fixedly connected to the first connecting flange. A hemispherical cover is fixed to the end of the second connecting flange, and a ventilation opening is provided through the outer peripheral side of the hemispherical cover.

[0019] The invention is further configured such that two symmetrical notched rings are fixed on the outer peripheral side of the cover.

[0020] The fixing assembly includes a rotating component that is rotatably fitted onto the cover component and two fixing components that are inserted and fixed onto the rotating component.

[0021] The rotating component includes two hinged cylindrical frames, each with two symmetrical rotating grooves inside, which are rotatably engaged with the notched ring.

[0022] The present invention is further configured such that: two connecting lugs that fit together are fixed on the outer peripheral sides of both cylindrical frames, and the two connecting lugs are fixedly connected by bolts.

[0023] The cylindrical frame described above has two symmetrical threaded columns fixed at both ends.

[0024] The other cylindrical frame has through holes at both ends for fixed connection with the locomotive motor.

[0025] The present invention is further configured such that: the fixing member includes a semi-circular cover ring plate, and the top of the semi-circular cover ring plate has two symmetrical insertion holes, which are respectively inserted into and engaged with two threaded posts.

[0026] A semicircular ring is fixed to the bottom of the semicircular cover plate, and several protrusions are fixed to the inner wall of the semicircular ring. Limiting baffles are fixed to both ends of the semicircular ring.

[0027] The present invention is further configured such that: a plurality of rectangular sliding columns are slidably fitted through the outer periphery of the cover cylinder; a first connecting column is fixed at the end of the rectangular sliding column inside the cover cylinder; a pressure plate adapted to the locomotive motor is fixed at the end of the first connecting column; a top plate is fixed at the opposite end of the rectangular sliding column outside the cover cylinder; and a buffer spring sleeved on the rectangular sliding column is fixed between the top plate and the cover cylinder.

[0029] The outer periphery of the cover has a through opening adapted to the locomotive motor.

[0030] The advantages of this invention are: 1. This invention uses the circumferential rotation of the rotating column inside the circular hole to drive the rectangular spoiler to make irregular up-down and left-right swaying inside the cover, so that the several extension rods that slide against each other with the peripheral side of the rectangular spoiler will also slide irregularly in the up-down and left-right directions. Combined with the elastic force of the fixed connection between the circular base plate and the sliding plate, this will ultimately drive several heat-conducting components to make up-down reciprocating movements to different degrees on several mounting ports and several guide rods, thereby accelerating the flow of hot air generated during the operation of the locomotive motor inside the cover, improving the heat absorption efficiency of the several heat-conducting components, improving the heat dissipation efficiency of the locomotive motor during operation, and thus improving the heat dissipation efficiency of the locomotive motor during operation.

[0031] 2. This invention uses a hand-operated rotating fixing component to drive several protrusions fixed to the inner wall of the semi-circular ring to rotate synchronously in the circumferential direction. This causes several sliding balls to slide sequentially on the protrusions, thereby compressing the buffer spring fixed between the top plate and the cover cylinder. This causes several pressure plates to move slowly in the radial straight line inside the cover cylinder until the pressure plates come into contact with the locomotive motor, thus securing the locomotive motor and ensuring the subsequent ventilation and cooling process.

[0048] Example 1, please refer to Figures 1-12 The present invention provides the following technical solutions:

[0049] An integrated cooling system for locomotives, specifically, includes a locomotive motor 1, an external enclosure for the locomotive motor 1 with a ventilation assembly 2 and a fixing assembly 3 rotatably fitted onto the ventilation assembly 2; the ventilation assembly 2 includes a ventilation component 4 covering the locomotive motor 1, a cover component 5 fixedly installed at the end of the ventilation component 4, several heat-conducting components 6 radially slidably fitted onto the cover component 5, and a baffle component 7 installed inside the ventilation component 4; the ventilation component 4 includes a shroud 401, with several mounting ports 402 extending through its outer periphery, a cross plate 403 fixedly attached to the inner wall of the shroud 401 near one port, and several heat-conducting components 6 slidably attached to the inner wall of the shroud 401 near the cross plate 403. The guide rods 404 are fitted together, and a circular base plate 405 is fixedly connected to the ends of several guide rods 404. An elastic spring 406 is fixedly fitted to the end of the circular base plate 405 and fitted on the guide rod 404. A rotating disk 407 is rotatably fitted through the side of the cross plate 403 inside the cover 401. A rotating column 408 is fixed at the end of the rotating disk 407 off-center. The end of the elastic spring 406 is fixedly connected to the heat-conducting component 6. The baffle 7 includes a rectangular baffle plate 701, which is slidably fitted with several heat-conducting components 6. A circular hole 702 is opened through the center of the rectangular baffle plate 701. A bearing is installed in the circular hole 702. The rotating column 408 passes through the inner ring of the bearing and rotatably fits with it.

[0050] Furthermore, guide grooves 409 are provided on both opposite sides of several mounting ports 402; the heat-conducting component 6 includes an arc-shaped heat-absorbing plate 601 that slides on the mounting port 402 (the arc length of the mounting port 402 is greater than the arc length of the arc-shaped heat-absorbing plate 601 to prevent the heat-conducting component 6 from getting stuck when sliding on the mounting port 402, and a high-temperature resistant elastic rubber is fixed between the gap between the mounting port 402 and the arc-shaped heat-absorbing plate 601 to facilitate the reciprocating sliding of the heat-conducting component 6 inside the mounting port 402 while the mounting port 402 is in a relatively sealed state), and several heat dissipation fins 602 are fixed on the outer wall of the arc-shaped heat-absorbing plate 601; the several heat dissipation fins 602 are provided on both opposite sides. Each surface is fixed with a sliding block 603, and the two sliding blocks 603 are respectively slidably engaged with the two guide grooves 409; a sliding plate 604 is fixed to the bottom of one sliding block 603, and a guide hole 605 is opened through the top of the sliding plate 604, which is slidably engaged with the guide rod 404; an extension rod 606 is fixed to the bottom of the sliding plate 604, which is slidably engaged with the rectangular spoiler 701; the bottom of the extension rod 606 is spherical; the end of the elastic spring 406 is fixedly connected to the bottom of the sliding plate 604; a dual-axis motor 410 is fixed to the side of the cross plate 403 outside the cover 401; one output shaft of the dual-axis motor 410 is fixedly connected to the center position of the rotating disk 407; a ventilation fan 411 is fixed to the other output shaft of the dual-axis motor 410.

[0051] The specific application of this embodiment is as follows: When the locomotive motor 1 is working, the dual-shaft motor 410 is started synchronously, driving the ventilation fan 411 fixed to an output shaft to perform a suction operation, thereby allowing external air to enter the ventilation component 4 through the cover 5 (optionally, the cover 5 can be connected to the water-cooling equipment in the locomotive's internal integrated system, so that the suction operation of the ventilation fan 411 allows the cold air outside the water-cooling equipment in the integrated system to enter the ventilation component 4, thereby providing auxiliary ventilation and cooling for the locomotive motor 1 during operation). To further enhance the cooling effect, the locomotive motor 1 installed inside the ventilation assembly 2 is ventilated and cooled. Simultaneously with the start of the dual-shaft motor 410, the rotating disk 407 fixed to its other output shaft rotates synchronously, causing the rotating column 408 fixed at the off-center end of the rotating disk 407 to rotate circumferentially. This causes the rotating column 408 to rotate circumferentially within the circular hole 702 penetrating the center of the rectangular spoiler 701, thereby causing the rectangular spoiler 701 to move vertically, horizontally, and vertically inside the shroud 401. The irregular swaying of the rectangular spoiler 701 inside the shroud 401 causes it to sway irregularly in the up-down and left-right directions. Simultaneously, several extension rods 606, which slide against the peripheral side of the rectangular spoiler 701, slide irregularly in the up-down and left-right directions. This causes several heat-conducting components 6 to slide to different degrees inside several mounting ports 402. Combined with the elastic force of the fixed connection between the circular base plate 405 and the sliding plate 604, this drives the two sliding blocks 603 in the heat-conducting components 6 to slide in the two guide grooves 409. The components move up and down repeatedly to varying degrees, which in turn causes several heat-conducting components 6 to move up and down repeatedly to varying degrees on several mounting ports 402 and several guide rods 404. This continuously agitates the ventilation air entering the shroud 401, thereby accelerating the flow rate of the hot air generated during the operation of the locomotive motor 1 inside the shroud 401, improving the heat absorption efficiency of the heat-conducting components 6, and improving the heat dissipation efficiency of the locomotive motor 1 during operation.

[0052] Example 2, please refer to Figures 1-12This second embodiment is an improvement on the first embodiment as follows: Specifically, a first connecting flange 412 is fixed to the end of the cover cylinder 401 near the cross plate 403; the cover body 5 includes a second connecting flange 501 fixedly connected to the first connecting flange 412, and a hemispherical cover 502 is fixed to the end of the second connecting flange 501, with a ventilation opening 503 through the outer periphery of the hemispherical cover 502; two symmetrical notched rings 413 are fixed to the outer periphery of the cover cylinder 401; the fixing assembly 3 includes a rotating part 8 rotatably engaged with the cover body 5 and two... A fixing member 9 is inserted and fixed to the rotating member 8; the rotating member 8 includes two cylindrical frames 801 that are hinged together, each of the two cylindrical frames 801 having two symmetrical rotating grooves 802 inside, the rotating grooves 802 rotatingly engaging with the notched ring 413; two connecting ear plates 803 that fit together are fixed to the outer periphery of each of the two cylindrical frames 801, the two connecting ear plates 803 being fixedly connected by bolts; two symmetrical threaded posts 804 are fixed to both ends of one cylindrical frame 801; and fixing holes for fixed connection with the locomotive motor 1 are opened through both ends of the other cylindrical frame 801. 805; The fastener 9 includes a semi-circular cover ring plate 901, with two symmetrical insertion holes 902 through the top of the semi-circular cover ring plate 901, which are respectively inserted into two threaded posts 804; a semi-circular ring 903 is fixed to the bottom of the semi-circular cover ring plate 901, and several protrusions 904 are fixed to the inner wall of the semi-circular ring 903; limit baffles 905 are fixed to both ends of the semi-circular ring 903; several rectangular sliding posts 414 are slidably fitted through the outer circumference of the cover 401, and a first connecting post 41 is fixed at the end of the rectangular sliding post 414 inside the cover 401. 5. A pressure plate 416 adapted to the locomotive motor 1 is fixed to the end of the first connecting column 415. A top plate 417 is fixed to the other end of the rectangular sliding column 414 outside the cover 401. A buffer spring 418 sleeved on the rectangular sliding column 414 is fixed between the top plate 417 and the cover 401. A second connecting column 419 is fixed to the bottom of the top plate 417. A sliding ball 420 that slides with the protrusion 904 is fixed to the end of the second connecting column 419. A cover opening 421 adapted to the locomotive motor 1 is opened through the outer periphery of the cover 401.

[0053] The specific application of this embodiment two is as follows: Before ventilating and cooling the locomotive motor 1, the system covers the locomotive motor 1 with the cover opening 421 that penetrates the outer periphery of the cover cylinder 401, so that the cover opening 421 is engaged with the mounting base of the locomotive motor 1. Then, the external bolts threaded onto the two mating connecting lugs 803 are removed, thereby opening the two hinged cylindrical frames 801. Then, the opened two cylindrical frames 801 are covered onto the two notched rings 413, so that the two notched rings 413 are respectively rotatably mounted on the rotating grooves 802, so that the two hinges The cylindrical frame 801 is rotatably connected between the two notched rings 413. After the rotatable connection is completed, the two connecting lugs 803 are in a state of mutual contact. At this time, the two connecting lugs 803 are fixed again by external bolts. After the fixation is completed, the two insertion holes 902 through the top of the semi-circular cover ring 901 are respectively inserted into the two threaded posts 804 fixed at the end of the cylindrical frame 801, and fixed by the threaded rotatable connection between the external nut and the threaded post 804, thus forming a complete fixing component 3.

[0054] After the above preparations are completed, the fixing component 3 is rotated by hand, which drives the several protrusions 904 fixed on the inner wall of the semi-circular ring 903 to rotate circumferentially in sync. This causes the several sliding balls 420 to slide on the contours of the several protrusions 904 in sequence, thereby compressing the buffer spring 418 fixed between the top plate 417 and the cover 401. This causes the several pressure plates 416 to move slowly radially inside the cover 401 in sync until the several pressure plates 416 come into contact with the locomotive motor 1 and reach the required clamping force. Then, the rotation of the fixing component 3 is stopped. At this time, the fixing holes 805 that are respectively opened through both ends of the other cylindrical frame 801 and the positioning holes set on the locomotive motor 1 are simultaneously in a coaxial state (the opposite sides of the locomotive motor 1 mounting base have positioning holes corresponding to the fixing holes 805). Then, the coaxial fixing holes 805 and positioning holes are connected and fixed by external bolts.
