Description

Technical Field

[0001] The invention relates to the technical field of hydrogen exchange robots, and in particular to a mobile hydrogen exchange robot for hydrogen fuel heavy trucks. Background Art

[0002] Hydrogen heavy trucks have broad prospects and huge market potential. First of all, hydrogen heavy trucks have become one of the important technical paths to reduce carbon emissions and promote green transportation with their advantages of zero emissions, high energy density and long driving range. At present, in order to reduce the cost of hydrogen, the structure of heavy truck battery replacement is referred to when replacing hydrogen fuel, and a detachable structure is made. The upper frame structure of the hydrogen tank module can be hoisted by the hydrogen replacement robot, and the vehicle-mounted bottom bracket has a locking device to lock the lower frame of the module. The vehicle-mounted bottom bracket is fixed on the beam of the vehicle, and the empty hydrogen tank module on the heavy truck is hoisted and unloaded, and the full hydrogen tank module is replaced, and then the empty hydrogen tank module is filled with hydrogen. The storage and transportation cost under the hydrogen replacement mode is 1 / 3 of the storage and transportation cost of pure hydrogen for traditional vehicles, breaking the singleness of the hydrogen supply system, avoiding the energy loss generated during the repeated filling of hydrogen, and compressing the single hydrogen replacement process to 3-5 minutes. A set of hydrogen replacement system can replace up to 180 vehicles in 24 hours, and the gas supply capacity is equivalent to a 9-ton super-large hydrogen filling station, which greatly improves the filling capacity of hydrogen energy vehicles.

[0003] At present, hydrogen fuel heavy trucks are used for outdoor transportation services for a long time. In rainy and snowy weather, a lot of rain and snow are likely to gather on the top of the hydrogen tank module. When the empty hydrogen tank module is hoisted and replaced, the rain and snow are likely to be scattered everywhere, causing the electronic components in the hydrogen tank module to come into contact with the rain and snow during the hydrogen filling process. This can easily cause short circuits and damage to the electronic components in the hydrogen filling equipment, affecting the replacement of the hydrogen tank module. Summary of the invention

[0004] The present invention provides a mobile hydrogen changing robot for a hydrogen fuel heavy truck. The robot is equipped with a first air blowing nozzle fixed on a mounting plate during the lifting and replacement of a hydrogen tank module. In rainy and snowy weather, the nozzle can blow the rain and snow attached to the top of the hydrogen tank module to both sides, so that during the inflation process of the hydrogen filling device, the replaced hydrogen tank module can reduce the contact between rain and snow and the electronic equipment inside thereof, causing short circuit and damage. This solves the problem mentioned in the above background technology that when an empty hydrogen tank module is lifted and replaced, rain and snow are easily scattered to various places, causing the electronic components of the hydrogen filling device to contact with rain and snow during the hydrogen filling process of the hydrogen filling device, which is easy to cause short circuit and damage to the electronic components in the hydrogen filling device, thus affecting the replacement of the hydrogen tank module.

[0015] The present invention has the following beneficial effects:

[0016] 1. In this hydrogen fuel heavy truck mobile hydrogen refueling robot, the horizontal movement position of the mobile truss can be adjusted through the set slide rail, mobile platform, and first moving wheels, which facilitates adjusting the moving direction during the hoisting of the hydrogen tank module. The second moving wheels on the U-shaped seat can move on the mobile truss, achieving the purpose of adjusting the working positions of the U-shaped seat and the hoisting assembly. The servo hydraulic cylinder in the hoisting assembly can adjust the vertical movement position of the mounting plate and the positioning wedge blocks fixed on the mounting plate, so that when the positioning wedge blocks move downward, they can be inserted into the hoisting brackets fixed on the hydrogen tank module for positioning. When the rotating electric cylinder drives the block to rotate, it can be clamped under the hoisting bracket, facilitating the precise clamping of the hoisting bracket and the hoisting assembly, improving the stability of the hydrogen tank module hoisting. The first air blowing nozzle fixed on the mounting plate can blow the rain and snow attached to the top of the hydrogen tank module to both sides in rainy and snowy weather; Through the rack slidably connected to the mounting plate, when the hoisting assembly moves vertically, the rack can be made to contact the first corrugated plate on the U-shaped seat, enabling the rack to drive the gear to rotate, and causing the two first rotating rods to drive the second air blowing nozzle to continuously rotate reciprocally, which can clean the rain and snow on the top of the hydrogen tank module thoroughly, reducing the cleaning dead corners.

[0017] 2. In this hydrogen fuel heavy truck mobile hydrogen refueling robot, the sponge wiping block can wipe and adsorb the rain and snow attached to the side of the hoisted hydrogen tank module, thereby reducing the moisture on the hydrogen tank module. When the triangular抵触 head contacts the hoisted hydrogen tank module moving upward, it can achieve the purpose of联动 of the first抵触杆, mounting bracket, rocker, and sliding bracket, causing the sponge wiping block to extend out of the water collecting tank and automatically press against the side of the hydrogen tank module. When the hydrogen tank module moves vertically, the rain and snow can be wiped clean, so that when the replaced hydrogen tank module is being filled with hydrogen by the hydrogen filling equipment, the contact between rain and snow and the internal electronic equipment can be reduced, preventing short circuits and damage, which may affect the hydrogen filling operation of the hydrogen cylinder module, thereby improving the hydrogen filling efficiency; Through the water squeezing plate on the second rotating rod in the water collecting tank, when the sponge wiping block retracts into the water collecting tank, it deflects, automatically squeezing the water adsorbed in the sponge wiping block, enabling the water to fall to the bottom of the water collecting tank, thereby reducing the moisture in the sponge wiping block and facilitating better adsorption effect when the sponge wiping block works next time.

[0018] It should be noted that there is an unclear character "抵触" in the original text. I have translated it as "抵触" for now. You may need to check and correct it according to the actual situation.3. In the hydrogen fuel heavy truck mobile hydrogen refueling robot, water can be discharged and reused through the drain port provided at one end of the water collecting tank. When the two sealing plates provided on the drain port are attached to each other, water in the water collecting tank is prevented from spilling during the hoisting process. The water collecting tank provided at one end of the moving truss can recover and process the water in the water collecting tank, reducing waste of water resources and improving the environmental protection and energy-saving effect. The drain port can be inserted into the socket of the recovery water tank. At the same time, the conical contact piece of the socket can contact the second contact frame on the sealing plate, prompting the separation of the sealing plate and allowing the water in the water collecting tank to flow into the recovery water tank. The water can be filtered through the provided filter plate to improve the quality of the recovered water. The provided strip-shaped rod can drive the second corrugated plate to move when the triangular contact head is reset, enabling the conical contact frame and the contact column to be linked, and achieving the purpose of reciprocating cleaning of the surface of the filter plate by the brush plate, thereby improving the water flow rate and filtration effect in the drain port.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 efforts shall fall within the protection scope of the present invention.

[0031] Example 1, please refer to Figures 1 to 10 , a mobile hydrogen refueling robot for hydrogen fuel heavy trucks, including a mobile truss 1, mobile platforms 2 are fixed at both ends of the mobile truss 1, first moving wheels 3 are installed below the mobile platforms 2, a slide rail 4 is arranged below the mobile truss 1, the first moving wheels 3 are located on the slide rail 4, a C-shaped seat 5 is arranged on the mobile truss 1, second moving wheels 6 are installed on both sides of the C-shaped seat 5, two strip-shaped grooves 7 are opened on the mobile truss 1, and the second moving wheels 6 are located in the strip-shaped grooves 7; A hydrogen tank module 8 is arranged below the C-shaped seat 5, a lifting bracket 9 is fixed on the hydrogen tank module 8, a lifting assembly for lifting the lifting bracket 9 is arranged on the C-shaped seat 5, and a number of equally spaced first air blowing nozzles 10 are arranged on the lifting assembly.

[0032] The hoisting assembly includes a servo hydraulic cylinder 81. The servo hydraulic cylinder 81 is fixed on the C-shaped seat 5, and an installation plate 82 is fixed at the end of the piston rod of the servo hydraulic cylinder 81. Positioning wedge blocks 83 are fixed around the installation plate 82, and a number of rotary electric cylinders 84 are fixed on the installation plate 82. A clamping block 85 is fixed on the rotating end of the rotary electric cylinder 84. A number of first air blowing nozzles 10 are all installed on the installation plate 82.

[0033] Two first rotating rods 11 are rotatably connected to both sides of the installation plate 82. A number of second air blowing nozzles 12 are fixed on the first rotating rods 11. The second air blowing nozzles 12 are located on one side of the first air blowing nozzles 10. A gear 13 is fixed at one end of the first rotating rod 11. A rack 14 is meshed with the gear 13. The rack 14 is slidably connected to the installation plate 82, and a first spring 15 is connected between the rack 14 and the installation plate 82. First corrugated plates 16 are arranged on both sides of the C-shaped seat 5. One end of the rack 14 abuts against the first corrugated plate 16.

[0034] A hydrogen refueling base is provided on the hydrogen fuel heavy truck. The hydrogen refueling base is clamped with the bottom of the hydrogen tank module 8. At the same time, a hydrogen connector is provided on the hydrogen refueling base. The hydrogen connector is electrically connected to the bottom of the hydrogen tank module 8 by a quick plug-in connection structure. Refer to Figure 1-Figure 5 The first moving wheels 3 installed below the moving platform 2 roll on the slide rails 4, so as to adjust the position of the moving truss 1, and prompt the moving truss 1 and the hydrogen tank module 8 to be replaced to be on the same straight line. Secondly, the second moving wheels 6 installed on the C-shaped seat 5 roll on the two strip-shaped grooves 7 opened on the moving truss 1, so as to adjust the position of the C-shaped seat 5 and the hoisting assembly on the C-shaped seat 5, so that the hoisting assembly can be located directly above the hydrogen tank module 8 of the heavy truck. During hoisting, the servo hydraulic cylinder 81 of the hoisting assembly drives the installation plate 82 to move downward, so that the positioning wedge blocks 83 fixed around the installation plate 82 are inserted into the hoisting bracket 9 on the hydrogen tank module 8 for positioning, which can avoid the swing of the hydrogen tank module 8 during hoisting. Then, the rotating end of the rotary electric cylinder 84 drives the clamping block 85 to rotate, so as to achieve the purpose that the clamping block 85 is located on the hoisting bracket 9. At the same time, the hydrogen refueling base releases the clamping state of the hydrogen tank module 8. When the piston rod of the servo hydraulic cylinder 81 retracts, the purpose of hoisting the hydrogen tank module 8 on the heavy truck can be achieved. During the hoisting process, the quick plug-in connection structure between the hydrogen connector and the bottom of the hydrogen tank module 8 is separated, and the hydrogen tank module 8 gradually moves into the C-shaped seat 5. Among them, both the first moving wheels 3 and the second moving wheels 6 are driven by motors; When there is rain, snow or sleet on the top of the hydrogen tank module 8, start the first air blowing nozzles 10 fixed on the installation plate 82, so that the gas blown out by the first air blowing nozzles 10 blows the rain, snow or sleet to both sides of the hydrogen tank module 8. Refer to Figure 4-Figure 5, when the mounting plate 82 moves upward, it can drive the two racks 14 to move upward synchronously, so that one ends of the two racks 14 respectively contact the first corrugated plate 16 arranged on the C-shaped seat 5. The first spring 15 continuously stores and releases elastic force, so that when the rack 14 reciprocates, it can drive the gear 13 fixed to one end of the first rotating rod 11 to rotate, making the first rotating rod 11 drive the second air blowing nozzle 12 to swing. The initial state of the second air blowing nozzle 12 is inclined, so that rain and snow can be discharged to both sides of the hydrogen tank module 8, which can further improve the rain and snow removal effect on the top of the hydrogen tank module 8 and reduce the dead angle of removal.

[0035] Embodiment 2 is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 10 , a water collecting tank 17 is arranged on the C-shaped seat 5, a sponge wiping block 18 is arranged in the water collecting tank 17, a sliding bracket 19 is fixed on the sponge wiping block 18, and the sliding bracket 19 is elastically connected with the C-shaped seat 5 through a second spring 191.

[0036] A triangular contact head 20 is arranged below the water collecting tank 17, a first contact rod 21 is fixed on the triangular contact head 20, the first contact rod 21 is slidably connected to the C-shaped seat 5, and the triangular contact head 20 is elastically connected with the C-shaped seat 5 through a third spring 22.

[0037] An installation bracket 23 is fixed on the C-shaped seat 5, a seesaw 24 is rotatably connected to the installation bracket 23, the seesaw 24 is elastically connected with the installation bracket 23 through a first torsion spring 241, and the two ends of the seesaw 24 respectively contact the first contact rod 21 and the sliding bracket 19.

[0038] Two second rotating rods 25 are rotatably connected to the water collecting tank 17, a water squeezing plate 26 is fixed on the second rotating rods 25, and a second torsion spring 27 is connected between the second rotating rods 25 and the water collecting tank 17.

[0039] Two second contact rods 28 are slidably connected to both sides of the C-shaped seat 5, the second contact rods 28 are elastically connected with the C-shaped seat 5 through a fourth spring 29, a cavity 30 is formed on the C-shaped seat 5, a first contact frame 31 and a trapezoidal contact block 32 are respectively arranged in the cavity 30, the first contact frame 31 is elastically connected with the C-shaped seat 5 through a fifth spring 33, and the first contact frame 31 contacts the second contact rod 28, and the trapezoidal contact block 32 is fixed on the first contact rod 21.

[0040] Since the lifting brackets 9 fixed on the hydrogen tank module 8 prevent rain and snow from being discharged from both ends during the rain and snow removal process, it needs to be discharged from both sides of the hydrogen tank module 8, so that part of the rain and snow will adhere to the two side surfaces of the hydrogen tank module 8 and need to be wiped and adsorbed. Refer to Figure 3-Figure 10, when the hydrogen tank module 8 is lifted and moved upward, the triangular contact head 20 can be in contact with the hydrogen tank module 8, prompting the triangular contact head 20 to drive the first contact rod 21 to move horizontally on the C-shaped seat 5, and the third spring 22 is energized. During the movement of the first contact rod 21, it can achieve the purpose of contacting one end of the seesaw 24, prompting the seesaw 24 to rotate on the mounting bracket 23, and the first torsion spring 241 is energized. During the rotation of the seesaw 24, it can achieve the purpose of contacting the sliding bracket 19, prompting the sliding bracket 19 to slide on the C-shaped seat 5, and the second spring 191 is energized, pushing the sponge wiping block 18 out of the water collecting tank 17 so that it can abut against the surface of the hydrogen tank module 8. The sponge wiping block 18 can adsorb rainwater and partially melted snow water, and the unmelted snow is wiped downward to make it脱离 the surface of the hydrogen tank module 8, thereby reducing the rain and snow adhering to the hydrogen tank module 8. When the replaced hydrogen tank module 8 is being filled with hydrogen by the hydrogen filling device, the contact between rain and snow and the internal electronic devices is minimized, preventing short circuits and damage, which may affect the hydrogen filling operation of the hydrogen tank module 8, thereby improving the hydrogen filling efficiency; When the hydrogen tank module 8 moves directly above the working position of the hydrogen filling device, refer to Figure 4-Figure 10 , it is lowered into the hydrogen filling device through the lifting assembly. The hydrogen tank module 8 gradually disengages from the C-shaped seat 5 until the triangular contact head 20 releases the contact with the hydrogen tank module 8, enabling the reset of the triangular contact head 20. At the same time, through the linkage of the first contact rod 21, the mounting bracket 23, the seesaw 24, and the sliding bracket 19, the sponge wiping block 18 can retract into the water collecting tank 17. At the same time, the first contact frame 31 drives the trapezoidal contact block 32 to move horizontally, achieving the purpose of the trapezoidal contact block 32 contacting the first contact frame 31, causing the first contact frame 31 to slide vertically in the cavity 30 provided on the C-shaped seat 5, and the fifth spring 33 is energized. The first contact frame 31 can contact the two second contact rods 28 simultaneously, pushing the second contact rods 28 to slide on the C-shaped seat 5, and the fourth spring 29 is energized, causing the second contact rods 28 to push the water squeezing plates 26 fixed on the two second rotating rods 25 to deflect, and the second torsion spring 27 is energized. The deflected water squeezing plates 26 can squeeze the sponge wiping block 18 in the water collecting tank 17, prompting the rainwater to fall into the water collecting tank 17, reducing the moisture in the sponge wiping block 18, and facilitating a better adsorption effect when the sponge wiping block 18 works next time.

[0041] Embodiment 3 is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 10, a drain outlet 34 is fixed to one side of the water collecting tank 17. Sealing pieces 35 are slidably connected to both sides of the drain outlet 34. A second抵触架36 is fixed to the sealing piece 35, and the sealing piece 35 is elastically connected to the drain outlet 34 through a sixth spring 37. A filter plate 38 is fixed to the drain outlet 34. One end of the moving truss 1 is fixed with a recovery water tank 39. An insertion port 40 is fixed to the recovery water tank 39, and a conical抵触片41 is fixed to the insertion port 40.

[0042] A sliding rod 42 is fixed to the drain outlet 34. Two brush plates 43 are slidably connected to the sliding rod 42. The brush plates 43 are elastically connected to the drain outlet 34 through eighth springs 431, and the brush plates 43 abut against the surface of the filter plate 38. A抵触柱44 is fixed to the back of the brush plate 43. A conical抵触架45 abuts against the抵触柱44. The conical抵触架45 is elastically connected to the drain outlet 34 through a seventh spring 46. A strip-shaped rod 47 is fixed to the triangular抵触头20, and a second corrugated plate 48 is fixed to the strip-shaped rod 47. One end of the conical抵触架45 abuts against the second corrugated plate 48.

[0043] In order to reduce the waste of water resources and improve the environmental protection effect, it is necessary to recycle the water in the water collecting tank 17. Refer to Figure 6-Figure 9 , when the U-shaped seat 5 moves to one end of the moving truss 1, the drain outlet 34 of the water collecting tank 17 can be inserted into the insertion port 40 of the recovery water tank 39. At the same time, the conical抵触片41 fixed to the insertion port 40 can abut against the two second抵触架36, prompting the two second抵触架36 to drive the sealing pieces 35 to move synchronously in the opposite direction, so that the rainwater recovered in the water collecting tank 17 can be filtered through the filter plate 38 to improve the water recovery quality, and the filtered rainwater flows into the recovery water tank 39 for storage; In order to prevent the filter holes of the filter plate 38 from being blocked by impurities and affecting the rainwater flow efficiency, it is necessary to clean the filter holes of the filter plate 38. Refer to Figure 6-Figure 9 , when the hydrogen tank module 8 is lowered into the hydrogen filling device, when the triangular抵触头20 is reset, it can drive the strip-shaped rod 47 and the second corrugated plate 48 fixed to one end of the strip-shaped rod 47 to move horizontally synchronously, prompting the second corrugated plate 48 to abut against the conical抵触架45, so that the conical抵触架45 can move up and down reciprocally in the drain outlet 34. The seventh spring 46 continuously stores and releases elastic force. When the conical抵触架45 abuts against the抵触柱44 on the brush plate 43, the brush plate 43 can move reciprocally on the sliding rod 42, achieving the purpose of reciprocally cleaning the surface of the filter plate 38 by the brush plate 43, thereby improving the water flow speed and filtration effect in the drain outlet 34.
