This causes the transmission plate to rotate, and subsequently, the second sliding groove pushes the second cylindrical block to move along the inner side of the second sliding groove. This, in turn, causes the two clamping blocks to move closer to each other, achieving clamping and fixing of hydrogen tanks of different sizes. Furthermore, during the upward movement of the lifting plate, the driving rack moves upward. Through the meshing action between the driving rack, gear, and driven rack, the driven rack moves downward, causing the fixing ring to move vertically downward and fit over the outer side of the valve stem at the top of the hydrogen tank.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1 to 7As shown, this utility model provides a fixing device for transporting hydrogen energy hydrogen tanks, including a device housing 1. A placement groove 101 is formed at the bottom of the inner wall of the device housing 1. A connecting block 102 is fixedly connected to the left side of the device housing 1, and a fixing groove 103 is formed at the bottom of the connecting block 102. A lifting assembly 2 is installed on the top of the device housing 1. Transmission assemblies 3 are installed on both sides of the bottom of the lifting assembly 2. First fixing assemblies 4 are installed on both sides of the inner wall of the device housing 1. A connecting assembly 5 is installed on the right side of the device housing 1. The lifting assembly 2 includes a fixing frame 201 fixedly connected to the top of the device housing 1. A motor 202 is fixedly connected to the middle of the top of the fixing frame 201. A lead screw 203 is fixedly connected to the output shaft of the motor 202. A threaded tube 204 is threaded onto the outer side of the lead screw 203. A lifting plate 205 is fixedly connected to the bottom of the threaded tube 204. The transmission assembly 3 includes a fixing plate 301 fixedly connected to the front of the device housing 1. A fixing rod 302 is fixedly connected to the back of 301. A transmission plate 303 is movably sleeved on the outside of the fixing rod 302. A first sliding groove 304 is opened on the top of the front of the transmission plate 303, and a second sliding groove 305 is opened on the bottom of the front of the transmission plate 303. The first fixing component 4 includes a fixing tube 401 fixedly connected to the inner wall of the device housing 1. A movable rod 402 is movably sleeved on the inner side of the fixing tube 401. A clamping block 403 is fixedly connected to the end of the movable rod 402 away from the fixing tube 401. The second fixing component 6 includes an active rack 601 fixedly connected to the back of the lifting plate 205, a positioning strip 602 and a support plate 604 fixedly connected to the back of the inner wall of the device housing 1. A driven rack 603 is slidably sleeved on the front of the positioning strip 602. A gear 605 is movably sleeved on the inner side of the support plate 604. A connecting plate 606 is fixedly connected to the bottom of the front of the driven rack 603. A fixing ring 607 is fixedly connected to the front of the connecting plate 606.
[0027] In this embodiment, the fixing device is only applicable to tanks whose outer diameter and length change proportionally with the volume. When the hydrogen tank is placed inside the device housing 1, the motor 202 is started to drive the lead screw 203 to rotate. Under the threaded thrust of the lead screw 203, the threaded tube 204 drives the lifting plate 205 to move vertically upward, thereby driving the first cylindrical block 251 to slide upward along the inner side of the first slide groove 304, causing the transmission plate 303 to rotate. Then, the second slide groove 305 pushes the second cylindrical block 405 to move along the inner side of the second slide groove 305, thereby driving the two clamping blocks 403 to move closer to each other, thus achieving clamping and fixing of hydrogen tanks of different sizes.
[0028] Furthermore, as the lifting plate 205 moves upward, it drives the active rack 601 to move upward. Through the meshing action between the active rack 601, the gear 605, and the driven rack 603, the driven rack 603 moves downward, thereby causing the fixing ring 607 to move vertically downward and be fitted onto the outside of the valve stem at the top of the hydrogen tank. This further protects and secures the hydrogen tank, preventing it from shaking or falling during transportation.
[0029] When the connecting block 102 of one device is inserted into the inner side of the connecting frame 501 of another device, the inclined surface on the right side of the wedge block 506 is pressed downward by the connecting block 102. After the connecting block 102 is installed in place, the wedge block 506 and the fixing groove 103 are exactly in the same vertical direction. The spring 504 drives the bottom plate 505 to move upward through the cylindrical rod 502, so that the wedge block 506 is inserted into the inner side of the fixing groove 103, completing the connection and fixation between the two devices, and improving the stability between multiple devices during transportation.
[0030] The lifting plate 205 has positioning rods 206 fixedly connected to both sides of its top. The top of the positioning rods 206 is movably sleeved with positioning tubes 207. The top of the positioning tubes 207 is fixedly connected to the top of the inner wall of the fixed frame 201.
[0031] The positioning rod 206 and the positioning tube 207 work together to position the lifting plate 205, so that when the screw 203 rotates, the threaded tube 204 can drive the lifting plate 205 to move up and down.
[0032] The lifting plate 205 has a first cylindrical block 251 fixedly connected to both its front and back sides. The end of the first cylindrical block 251 away from the lifting plate 205 is fixedly connected to a first stop block 252. The first cylindrical block 251 is slidably sleeved with the first sliding groove 304. The clamping block 403 has a second cylindrical block 405 fixedly connected to both its front and back sides. The end of the second cylindrical block 405 away from the clamping block 403 is fixedly connected to a second stop block 406. The second cylindrical block 405 is slidably sleeved with the second sliding groove 305.
[0033] When the lifting plate 205 moves the first cylindrical block 251 downward, the bottom of the transmission plate 303 moves toward the side wall of the device housing 1, thereby causing the two clamping blocks 403 to move away from each other. Conversely, when the lifting plate 205 moves the first cylindrical block 251 upward, the bottom of the transmission plate 303 moves away from the side wall of the device housing 1.
[0034] The clamping block 403 is fixedly connected to an inner liner 404, which is made of rubber. The inner liner 404 can increase the contact area and friction with the surface of the hydrogen tank, improve the stability of the fixation, and reduce the wear of the contact surface.
[0035] The connecting component 5 includes a connecting frame 501 fixedly connected to the right side of the device housing 1. A cylindrical rod 502 is movably sleeved on the top of the connecting frame 501. A top plate 503 is fixedly connected to the top of the cylindrical rod 502. A spring 504 is provided on the outside of the cylindrical rod 502. The spring 504 is located between the top plate 503 and the top of the connecting frame 501. A bottom plate 505 is fixedly connected to the bottom of the cylindrical rod 502. A wedge block 506 is fixedly connected to the middle of the top of the bottom plate 505.
[0036] The wedge block 506 has an inclined surface on the right side of its top, and the wedge block 506 is compatible with the fixing groove 103. The left edge of the connecting block 102 has a chamfer.
[0037] Working principle and usage process of this utility model:
[0038] When the hydrogen tank is placed inside the housing 1, the motor 202 is started to drive the lead screw 203 to rotate. Under the thread thrust of the lead screw 203, the threaded tube 204 drives the lifting plate 205 to move vertically upward, thereby driving the first cylindrical block 251 to slide upward along the inner side of the first slide groove 304, causing the transmission plate 303 to rotate. Then, the second slide groove 305 pushes the second cylindrical block 405 to move along the inner side of the second slide groove 305, thereby driving the two clamping blocks 403 to move closer to each other, so as to clamp and fix hydrogen tanks of different sizes.
[0039] Furthermore, as the lifting plate 205 moves upward, it drives the active rack 601 to move upward. Through the meshing action between the active rack 601, the gear 605, and the driven rack 603, the driven rack 603 moves downward, thereby causing the fixing ring 607 to move vertically downward and be fitted onto the outside of the valve stem at the top of the hydrogen tank. This further protects and secures the hydrogen tank, preventing it from shaking or falling during transportation.
[0040] When the connecting block 102 of one device is inserted into the inner side of the connecting frame 501 of another device, the inclined surface on the right side of the wedge block 506 is pressed downward by the connecting block 102. After the connecting block 102 is installed in place, the wedge block 506 and the fixing groove 103 are exactly in the same vertical direction. The spring 504 drives the bottom plate 505 to move upward through the cylindrical rod 502, so that the wedge block 506 is inserted into the inner side of the fixing groove 103, completing the connection and fixation between the two devices, and improving the stability between multiple devices during transportation.
