Description

Technical Field

[0001] The present invention relates to the technical field of power supply vehicles, and particularly to a deployable emergency hydrogen energy power supply vehicle. Background Art

[0002] Under the background of social development, the development and utilization of clean energy have gradually become an urgent need today. Hydrogen energy, as a secondary clean energy, is highly expected and becomes a powerful support for promoting the transformation of clean and efficient energy. The deployable emergency hydrogen energy power supply vehicle is a new type of emergency power supply equipment that combines hydrogen fuel cell technology, solid-state hydrogen storage system and mobile power platform, and has the characteristics of rapid deployment, high-efficiency energy supply, low-carbon environmental protection, etc.

[0003] The cable is a main component for transporting electricity in the power supply vehicle. After the carriage of the power supply vehicle is unfolded, the cable is unfolded from the cable reel for use. When the cable transports electricity, it will generate a certain amount of heat. And when part of the cable is not fully released, the unreleased part of the cable will have a problem of heat accumulation at the cable reel. The cable is in a high-temperature environment for a long time. Because of the excessive heat, it will cause the thermal degradation of the insulating material, reduce the insulation resistance, and increase the probability of breakdown risk; at the same time, the high temperature will also accelerate the oxidation process of the cable, increase the conductor resistance, and form a vicious cycle of "resistance increase → more heat generation → higher temperature", further shortening the service life of the cable.

[0004] During the winding or releasing process of the existing cable, due to the vibration of the vehicle during operation, the cable becomes loose. The loose cable needs extra time to be sorted out, delaying the restoration of power supply and affecting the emergency support ability of key facilities. Summary of the Invention

[0053] Next, the accompanying drawings in the embodiments of the present invention will be combined to clearly and completely describe the technology in the embodiments of the present invention. An expandable emergency hydrogen energy power vehicle. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0054] As Figures 1 - 15 shown, the present invention provides: An expandable emergency hydrogen energy power vehicle, including a cable winder 10 fixed in the compartment 70. The bracket of the cable winder 10 is fixed in the compartment 70, and a servo motor is fixed on the vehicle frame. The cable winder 10 includes a winding shaft 11 for winding cables. The winding shaft 11 is rotatably connected to the bracket through the cooperation of a bearing and a bearing seat, and is driven by a synchronous pulley and a synchronous belt with the output shaft of the servo motor;

[0055] A winding separation component 20 is coaxially sleeved on the winding shaft 11. The winding separation component 20 includes an inner separation unit 21 sleeved on the winding shaft 11 for winding cables, and an outer separation unit 22 for winding cables is coaxially sleeved outside the inner separation unit 21;

[0056] Both the inner separation unit 21 and the outer separation unit 22 slide along the radial direction of the winding shaft 11, thereby realizing the adjustment of the outer diameters of the inner separation unit 21 and the outer separation unit 22. Finally, the tension of the wound cable is adjusted through the adjustment of the outer diameter, and during the tensioning process, the cable wound on the winding shaft 11 will also be tightened. Therefore, the problem of cable looseness is avoided through the adjustment of the tension;

[0057] Among them, when winding the cable, the servo motor drives the winding shaft 11 to start winding the cable. After the cable is wound in one layer, the cable is then wound on the inner separation unit 21. After the inner separation unit 21 rotates following the winding shaft 11 and winds the cable, finally the outer separation unit 22 rotates following the winding shaft 11 and winds the cable, so as to realize the hierarchical winding of the cable from the inside to the outside in sequence. After the cable is hierarchically wound, the cable forms a heat dissipation channel after being layered by the inner separation unit 21 and the outer separation unit 22, avoiding the mutual contact of the cables after multi-layer winding. Through the formed heat dissipation channel, the heat dissipation area of the cable is increased, avoiding the problem of heat accumulation;

[0058] Finally, when the cable after hierarchical winding becomes loose, through the radially outward sliding adjustment of the inner separation unit 21 and the outer separation unit 22, the outer diameters of the inner separation unit 21 and the outer separation unit 22 are enlarged, realizing the hierarchical tensioning of the cable, and making the tensioning of the cable more relaxed through the way of hierarchical tensioning.

[0059] As Figures 5 - 15 shown, the inner separation unit 21 includes two inner ring plates 211 rotatably connected to the winding shaft 11 through bearings, and the two inner ring plates 211 are arranged at both ends of the winding shaft 11. A plurality of annularly distributed inner retaining rods 212 are radially slidably connected between the two inner ring plates 211. The plurality of annularly distributed inner retaining rods 212 form a wire winding component. By sliding the inner retaining rods 212 along the radial direction of the inner ring plates 211 (that is, the radial direction of the winding shaft 11), the outer diameter adjustment of the inner separation unit 21 is realized;

[0060] The outer separation unit 22 includes an outer ring plate 221 coaxially and rotatably connected to the inner ring plate 211 through a bearing. A plurality of annularly distributed outer retaining rods 222 are radially slidably connected between the two outer ring plates 221. The plurality of annularly distributed outer retaining rods 222 form a wire winding component, and by sliding the outer retaining rods 222 along the radial direction of the outer ring plate 221, the outer diameter adjustment of the outer separation unit 22 is realized;

[0061] As Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 shown, a inner layering rod 213 is radially slidably connected to the inner ring plate 211, and an outer layering rod 223 is radially slidably connected to the outer ring plate 221; a cable axial movement port is formed between two inner retaining rods 212 close to the inner layering rod 213, and a cable axial movement port is formed between two outer retaining rods 222 close to the outer layering rod 223. One end of the cable passes through the two cable axis movement ports;

[0062] And between the inner layered rod 213 and the inner ring plate 211, and between the outer layered rod 223 and the outer ring plate 221, a cable channel 23 larger than the outer diameter of the cable is reserved, so as to facilitate the cable to enter the winding layer of the inner separation unit 21 or the winding layer of the outer separation unit 22 through the cable channel 23;

[0063] Axially sliding plugs 30 are inserted on both the inner ring plate 211 and the outer ring plate 221. The self-locking device 30 includes a plug 31 for axially inserting on the winding shaft 11;

[0064] When the winding shaft 11 winds the cable, the two plugs 31 are in a state of not being connected to the winding shaft 11 at this time. The winding shaft 11 rotates independently and winds the cable at this time. When the cable reaches the position of the cable channel 23, the plug 31 on the inner ring plate 211 is inserted on the winding shaft 11. At this time, the inner ring plate 211, the inner retaining rod 212 and the inner layered rod 213 rotate together. When the cable passes through the cable channel 23 and abuts against the inner retaining rod 212 on one side of the cable axis moving port, the winding component formed by the multiple inner retaining rods 212 starts to wind the cable;

[0065] When the cable winds and moves to the position of the cable channel 23 formed between the outer ring plate 221 and the outer layered rod 223, the plug 31 is inserted on the winding shaft 11. At this time, the outer separation unit 22 and the inner separation unit 21 rotate with the winding shaft 11. After the cable passes through the cable channel 23 at this place and abuts against the outer retaining rod 222, the winding component formed by the multiple outer retaining rods 222 starts to wind the cable, thus completing the layered winding of the cable.

[0066] Such as Figure 10 、 Figure 14 As shown, the two cable channels 23 are placed at both ends of the winding shaft 11. That is, when winding the cable, the winding shaft 11 is driven by a servo motor to start winding from one end (the starting end). After reaching the other end (the winding end), it reaches the cable channel 23 at the inner ring plate 211. At this time, the cable is wound in one layer. Subsequently, the cable enters the inner separation unit 21 through the cable channel 23. The cable is wound on the inner separation unit 21. The inner separation unit 21 rotates with the winding shaft 11 and starts to wind the cable from the winding end. After reaching the starting end, the cable is wound in one layer on the inner separation unit 21 and comes to the cable channel 23 on the side of the outer separation unit 22. The cable winds on the outer separation unit 22 from the starting end to the winding end again, so that the cable can be wound in three layers, and each layer is independently separated. The layered independent heat dissipation greatly avoids the accumulation of cable heat.

[0067] Such as Figure 6 、 Figure 12 、 Figure 15As shown in the figure, first sliders 24 are fixed to both ends of the inner retaining rod 212 and the outer retaining rod 222. First sliders 24 are also fixed to one end of each of the inner layer-dividing rod 213 and the outer layer-dividing rod 223. A plurality of chutes 26 adapted to the first sliders 24 are formed in both the inner ring plate 211 and the outer ring plate 221. The chutes 26 are arranged along the radial direction of the winding shaft 11, so that the first sliders 24 are slidably engaged with the chutes 26, enabling the inner retaining rod 212 and the outer retaining rod 222 to slide radially along the winding shaft 11 with the cooperation of the first sliders 24;

[0068] Meanwhile, a plurality of tension springs 25 are fixed between one side of the first slider 24 close to the winding shaft 11 and the chute 26. When the cable is in a tensioned state during winding, the inner retaining rod 212 and the outer retaining rod 222 will be squeezed by the cable during winding, causing the first slider 24 to compress the tension spring 25 to generate an elastic rebounding force towards the outside. Therefore, when the cable winding becomes loose, through the elastic rebounding of the tension spring 25, it can automatically compensate for the tension, and the cable can always be kept in a tensioned state without manual adjustment.

[0069] As Figures 10 - 15 shown in the figure, guide holes 27 are formed in both the inner ring plate 211 and the outer ring plate 221. A pressing seat 32 is slidably arranged in the guide holes 27. The pressing seat 32 is fixed to the plug pin 31. A return spring 33 is fixed to one side of the pressing seat 32 close to the plug pin 31, and the return spring 33 is fixed to the inner wall of the guide hole 27;

[0070] The pressing seat 32 is arranged at the cable passage 23;

[0071] First baffles 12 and second baffles 13 are coaxially fixed to both ends of the winding shaft 11 respectively. A plurality of first pin holes 121 are annularly distributed on the first baffle 12, and a plurality of second pin holes 131 are annularly distributed on the second baffle 13. Among them, the plug pins 31 on the inner ring plate 211 correspond to and are adapted to the second pin holes 131, and the plug pins 31 on the outer ring plate 221 correspond to and are adapted to the first pin holes 121;

[0072] Under normal conditions (that is, when the pressing seat 32 is not squeezed by the cable), the return spring 33 elastically rebounds, causing the pressing seat 32 to protrude outwards, and at the same time the plug pin 31 disengages from the pin hole. At this time, the inner separation unit 21 and the outer separation unit 22 do not rotate with the winding shaft 11;

[0073] When the winding shaft 11 starts to wind the cable, and when the cable winds along the axis to the pressing seat 32 at the inner ring plate 211, the cable squeezes the pressing seat 32 and causes the return spring 33 to be squeezed to generate an elastic rebound force. At the same time, the bolt 31 is inserted into the second pin hole 131. At this time, the inner ring plate 211 can rotate with the winding shaft 11, and when the cable enters the inner partition unit 21 through the cable channel 23 for winding, when the cable reaches the pressing seat 32 at the outer ring plate 221, the cable squeezes this pressing seat 32, and causes the bolt 31 to be inserted into the first pin hole 121. At this time, the outer ring plate 221 can rotate with the winding shaft 11 and start to wind the cable;

[0074] When the cable is released, the cable is gradually released and reaches the pressing seat 32 of the outer ring plate 221. Then, the cable on the outer partition unit 22 is all released. When the cable continues to be released and no longer squeezes this pressing seat 32, at this time, under the elastic rebound of the return spring 33, the bolt 31 disengages from the first pin hole 121, and the cable axially moves within the cable axis movement port of the outer partition unit 22, and the outer partition unit 22 no longer rotates with the winding shaft 11;

[0075] At this time, start to release the cable wound on the inner partition unit 21. The cable is gradually released and reaches the position of the pressing seat 32 of the inner ring plate 211. Then, the cable on the inner partition unit 21 is all released. When the cable continues to be released and no longer squeezes the pressing seat 32 at this place, at this time, under the elastic rebound of the return spring 33, the bolt 31 disengages from the second pin hole 131, and the cable axially moves within the cable axis movement ports of the inner partition unit 21 and the outer partition unit 22, and at this time, the inner partition unit 21 and the outer partition unit 22 do not rotate with the winding shaft 11;

[0076] Finally, release the cable on the winding shaft 11, and finally the cable can be released layer by layer, and they do not affect each other.

[0077] As Figure 8 、 Figure 11 shown, the relative side edges of the first pin hole 121 and the second pin hole 131 are both arc surface structures to form a flared opening, and the ends of the bolt 31 away from the pressing seat 32 are both conical structures;

[0078] In the normal state (that is, when the pressing seat 32 is not squeezed by the cable), the conical part of the bolt 31 protrudes from the baffle, that is, the conical part of the bolt 31 is placed in the flared opening of the pin hole. When the inner ring plate 211 and the outer ring plate 221 do not rotate with the winding shaft 11, the slope of the flared opening of the pin hole will squeeze the conical part of the bolt 31, and when the bolt 31 crosses the flared opening, it can automatically snap into the next pin hole to avoid the problem that the bolt 31 gets stuck on the side wall of the ring plate when being inserted into the pin hole and cannot be inserted.

[0079] As Figure 2 、Figure 3 , Figure 8 As shown in Figure 8 , the winding shaft 11 is a circular tube structure with an opening at one end. A plurality of ventilation holes 111 are provided on the surface of the winding shaft 11. A blower 40 is fixed on the cable take-up machine 10 at the opening side of the winding shaft 11 to blow air into the winding shaft 11 through the blower 40, and the air flow is dispersed through the ventilation holes 111, and the cable is cooled through the ventilation holes 111 to improve the heat dissipation effect of the cable.

[0080] As Figure 3 , Figure 4 , Figure 5 As shown in Figure 5 , a linear module 50 is fixed on one side of the chassis of the cable take-up machine 10. The linear module 50 includes a second slider 51 that moves along the axis direction of the winding shaft 11. A guide seat 52 for the cable to pass through is fixed on the second slider 51. The second slider 51 drives the guide seat 52 to move horizontally, so as to drive the cable to move along the axis of the winding shaft 11 during winding, and by adjusting the rotation speed of the servo motor of the linear module 50, the spacing between the cables wound in each layer is adjusted to ensure that there are gaps between the cables in each layer, so that the air flow can circulate when the blower 40 ventilates.

[0081] As Figure 2 As shown in Figure 2 , a slip ring 60 is fixed on the bracket of the cable take-up machine 10 at the opening of the winding shaft 11. The cable can be connected through the slip ring 60, so that the normal use of the cable joint is not affected during the winding or release process of the cable. At the same time, the slip ring 60 is fixed on the side close to the blower 40, and when the blower 40 is running, it can also play a role in cooling the slip ring 60.

[0082] Working principle: When all the cables are released, one end of the cable passes through the winding shaft 11 and is fixed on the rotor of the slip ring 60. At this time, the end of the winding shaft 11 close to the slip ring 60 is the starting end of winding. At the same time, the cable passes through two cable axis movement ports, and the two pressing seats 32 are not extruded by the cable. The plug 31 is disengaged from the pin hole, and the inner partition unit 21 and the outer partition unit 22 are rotatably connected to the winding shaft 11;

[0083] The cable take-up machine 10 runs to drive the winding shaft 11 to rotate and start winding the cable, and moves to the pressing seat 32 position of the inner ring plate 211 (that is, the end of winding) through the drive of the second slider 51. Continue to wind the cable to squeeze the pressing seat 32 and make the return spring 33 be squeezed to generate an elastic rebound force. At the same time, the plug 31 is inserted into the second pin hole 131. At this time, the inner ring plate 211, the inner blocking rod 212 and the inner layer dividing rod 213 rotate with the winding shaft 11, and when the cable passes through the cable channel 23 and enters the inner partition unit 21 to wind the cable;

[0084] When the cable moves towards the starting end of winding driven by the second slider 51 and reaches the pressing seat 32 at the outer ring plate 221, the cable presses the pressing seat 32, causing the plug pin 31 to insert into the first pin hole 121. At this time, the outer ring plate 221, the outer blocking rod 222 and the outer delaminating rod 223 rotate following the winding shaft 11 and start to wind the cable, thus completing the layered winding of the cable.

[0085] When the cable needs to be released, when the cable is gradually released by pulling it outwards and reaches the pressing seat 32 of the outer ring plate 221, the cable on the outer separation unit 22 is completely released. When the cable continues to be released and no longer presses the pressing seat 32, at this time, under the elastic rebound of the return spring 33, the plug pin 31 disengages from the first pin hole 121, and the cable axially moves within the cable axis movement opening of the outer separation unit 22, and the outer separation unit 22 no longer rotates following the winding shaft 11.

[0086] When continuing to pull, the cable wound on the inner separation unit 21 starts to be released. When the cable is gradually released and reaches the position of the pressing seat 32 of the inner ring plate 211, the cable on the inner separation unit 21 is completely released. When the cable continues to be released and no longer presses the pressing seat 32 at this place, at this time, under the elastic rebound of the return spring 33, the plug pin 31 disengages from the second pin hole 131, and the cable axially moves within the cable axis movement openings of the inner separation unit 21 and the outer separation unit 22, and at this time, the inner separation unit 21 and the outer separation unit 22 do not rotate following the winding shaft 11.

[0087] Finally, the cable on the winding shaft 11 can be released.

[0088] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
