Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application. EMBODIMENT

[0041] Please refer to Figures 1-6 , which is a structural schematic view of the solid-state hydrogen storage material layered feeding device in the embodiments of the present application.

[0042] The present embodiment provides a solid-state hydrogen storage material layered feeding device, which comprises a weight mechanism 1, a rotating mechanism 2 and at least two feeding mechanisms 3. Since the solid-state hydrogen storage material comprises different materials or materials in different structural states, the solid-state hydrogen storage materials of different materials need to be placed in layers, so at least two feeding mechanisms 3 are provided for respectively storing different solid-state hydrogen storage materials to realize layered feeding. Specifically, the present embodiment takes two feeding mechanisms 3 as an example, and respectively takes the powdery solid-state hydrogen storage material 8 and the granular solid-state hydrogen storage material 7 as an example for illustration.

[0043] The weighing mechanism 1 is arranged on one side of the rotating mechanism 2, and is used for mounting the hydrogen storage bottle 4 and monitoring the weight of the hydrogen storage bottle 4 in real time. Through the weight change of the hydrogen storage bottle 4, the feeding amount of the feeding mechanism 3 can be controlled, so as to realize precise feeding. The two feeding mechanisms 3 are arranged along the circumference of the rotating mechanism 2, so that the two feeding mechanisms 3 or even multiple feeding mechanisms 3 can rotate around the same center, so that each feeding mechanism 3 can be rotated to the position of the hydrogen storage bottle 4. The feeding mechanism 3 includes a hopper 31 and a feeding assembly 32. The hopper 31 is arranged on the rotating mechanism 2, the top of the hopper 31 is open, and a hopper cover 33 is arranged at the opening. The hopper cover 33 is slightly larger than the top end of the hopper 31, and when the remaining amount of hydrogen storage material is insufficient, the hopper cover 33 can be opened for feeding. One end of the feeding assembly 32 is connected with the hopper 31, and the other end of the feeding assembly 32 is located at a position vertically above the hydrogen storage bottle 4, that is, the other end of the feeding assembly 32 coincides with the projection of the circumference of the hydrogen storage bottle 4 in the vertical direction, so that the feeding assembly can feed the material downward into the hydrogen storage bottle. The rotating mechanism 2 is used to drive the feeding mechanism 3 to rotate, so that the feeding assembly 32 is opposite to the bottle opening of the hydrogen storage bottle 4. When one of the feeding mechanisms 3 rotates to the position that the feeding assembly 32 is opposite to the bottle opening of the hydrogen storage bottle 4, feeding can be performed. After feeding is completed, the rotating mechanism 2 continues to rotate, so that the next feeding mechanism 3 rotates to the position that the feeding assembly 32 thereof is opposite to the bottle opening of the hydrogen storage bottle 4, and feeding is performed, thereby realizing automatic layered feeding operation in the hydrogen storage bottle 4.

[0044] As an example, as Figure 3 The weighing mechanism 1 is arranged on the bottom plate 5, and the weighing mechanism 1 includes a weighing sensor 11, a limiting plate 12 and a plurality of limiting support rods 13. The weighing sensor 11 is embedded in the bottom plate 5. Specifically, a groove can be arranged on the bottom plate 5 for mounting the weighing sensor 11, so that the weighing sensor 11 is as flat as possible with the plane of the bottom plate 5, thereby ensuring that the hydrogen storage bottle 4 is placed stably. The plurality of limiting support rods 13 are arranged around the weighing sensor 11 on the bottom plate 5. Specifically, a fixing hole can be arranged on the bottom plate 5, and the fixing hole is fixedly connected by being screwed from the bottom, thereby achieving firm connection. The limiting plate 12 is arranged on the top of the plurality of limiting support rods 13, and the limiting plate 12 is provided with a limiting hole through which the hydrogen storage bottle 4 passes. The limiting plate 12 and the plurality of limiting support rods 13 can support and limit the hydrogen storage bottle 4, prevent the hydrogen storage bottle 4 from shaking or falling, affect feeding, and facilitate installation and removal of the hydrogen storage bottle 4.

[0045] As an example, the rotating mechanism 2 is arranged on the bottom plate 5, and the rotating mechanism 2 comprises a support, a rotating disc 21 and a driving assembly. The support is arranged on the bottom plate 5 and located at one side of the weighing mechanism 1. The driving assembly is installed on the support. The rotating disc 21 is rotationally arranged on the top of the support, and the center of the rotating disc 21 is connected to the output end of the driving assembly. The support is used for supporting the driving assembly and the rotating disc 21. Two feeding mechanisms 3 are respectively arranged opposite to the edges of the rotating disc 21. The driving assembly drives the rotating disc 21 to rotate, thereby driving the two feeding mechanisms 3 to rotate.

[0046] Further, as Figure 2 The support comprises a fixed plate 22 and a plurality of fixed support rods 23. The plurality of fixed support rods 23 are arranged on the bottom plate 5. Specifically, the plurality of fixed support rods 23 can be fixed and connected by being screwed from the bottom through the fixed holes arranged on the bottom plate 5, similar to the limiting support rods 13. The fixed plate 22 is arranged on the top of the plurality of fixed support rods 23, and is used for installing the driving assembly. The driving assembly comprises a rotating motor 24 and a harmonic reducer 25. The rotating motor 24 is installed on the fixed plate 22. The harmonic reducer 25 is connected to the output end of the rotating motor 24. The output end of the harmonic reducer 25 is connected to the center of the rotating disc 21. The rotating motor 24 and the harmonic reducer 25 are used for controlling the rotation of the rotating disc 21, so that the rotating disc 21 rotates slowly and stably.

[0047] Further, one side of the rotating disc 21 is provided with a cutout 211. Specifically, the cutout 211 is a part of the side of the rotating disc 21 that is cut off, and the distance from the edge of the side to the center is reduced. The distance from the cutout 211 to the center of the rotating disc 21 is much smaller than the distance from the edge of other parts of the rotating disc 21 to the center. Therefore, the rotating disc 21 cannot cover the hydrogen storage bottle 4 at the cutout 211, and the hydrogen storage bottle 4 can be quickly disassembled and assembled from the cutout 211.

[0048] As an example, as Figure 4 and Figure 5 The conveying assembly comprises a conveying horizontal pipe 321, a conveying vertical pipe 322, a movable inner pipe 323, a conveying push rod 324, a threaded rod 325 and a driving member. One end of the conveying horizontal pipe 321 is connected to one side of the bin 31. One side of the conveying vertical pipe 322 is in communication with the other end of the conveying horizontal pipe 321, and the bottom of the conveying vertical pipe 322 is open. Therefore, the hydrogen storage material in the bin 31 can be conveyed from the conveying horizontal pipe 321 to the conveying vertical pipe 322, and then fall into the hydrogen storage bottle 4 from the bottom opening of the conveying vertical pipe 322.

[0049] The aforementioned movable inner tube 323 is axially movably inserted into the conveying vertical tube 322. The bottom of the movable inner tube 323 is open, and a slot 326 is formed on the upper part of the side of the movable inner tube 323 facing the conveying horizontal tube 321. By inserting the movable inner tube 323 into the conveying vertical tube 322, the connection between the conveying horizontal tube 321 and the conveying vertical tube 322 can be sealed to prevent the hydrogen storage material from slipping out. The slot 326 on the upper part of the side of the movable inner tube 323 facing the conveying horizontal tube 321 can be adapted to the diameter of the conveying horizontal tube 321. When the movable inner tube 323 moves downward until the slot 326 is opposite to the conveying horizontal tube 321, the conveying horizontal tube 321 and the movable inner tube 323 can be connected for material conveying. The outer diameter of the movable inner tube 323 is smaller than the inner diameter of the opening of the hydrogen storage bottle 4, and the center of the movable inner tube 323 and the center of the hydrogen storage bottle 4 are located at the projection position directly above the circumference of the center of the hydrogen storage bottle 4, so that the movable inner tube 323 can be inserted into the hydrogen storage bottle 4 to add material, avoiding splashing of hydrogen storage material during the addition process.

[0050] The aforementioned material conveying push rod 324 is disposed at the top of the conveying vertical pipe 322, and the telescopic end of the material conveying push rod 324 passes through the conveying vertical pipe 322 and is connected to the top end of the movable inner pipe 323; the material conveying push rod 324 pushes the movable inner pipe 323 to move up and down within the conveying vertical pipe 322, so that the slot 326 communicates with the conveying horizontal pipe 321, or so that the movable inner pipe 323 blocks the conveying horizontal pipe 321. Specifically, the aforementioned material conveying push rod 324 is preferably an electric push rod.

[0051] The aforementioned threaded rod 325 is transversely inserted into the lower part of the hopper 31, with one end connected to a conveying drive unit mounted on the turntable 21, and the other end inserted into the conveying horizontal pipe 321. The conveying drive unit is used to drive the threaded rod 325 to rotate. Specifically, the conveying drive unit drives the threaded rod 325 to rotate, and the rotation of the threaded rod 325 can push the hydrogen storage material in the hopper 31 to move from the conveying horizontal pipe 321 to the movable inner pipe 323, and finally from the movable inner pipe 323 to the hydrogen storage cylinder 4.

[0052] Furthermore, such as Figure 2 The aforementioned conveying vertical pipe 322 has an elongated hole 327 along its axial direction on one side. The telescopic end of the conveying push rod 324 is connected to the top of the movable inner pipe 323 through a limiting member. The limiting member passes laterally through the elongated hole 327 and can move up and down along the elongated hole 327. The limiting member can be a bolt. The movable inner pipe 323 and the conveying push rod 324 are connected and fixed by the bolt, and the bolt is inserted into the elongated hole 327. When the conveying push rod 324 pushes the movable inner pipe 323 up and down, the bolt can axially restrict the movable inner pipe 323 to prevent it from rotating, thereby preventing the slot 326 from aligning with the conveying horizontal pipe 321.

[0053] Furthermore, such as Figure 2The driving member includes a feeding motor 328 and a synchronous pulley set 329. The output shaft of the feeding motor 328 is connected to one end of the threaded rod 325 through the synchronous pulley set 329. The synchronous pulley set 329 specifically includes a first pulley, a second pulley and a synchronous belt. The first pulley is sleeved on the output shaft of the feeding motor 328, the second pulley is sleeved on one end of the threaded rod 325, and the first pulley and the second pulley are connected through the synchronous belt. When the feeding motor 328 rotates, the first pulley is driven to rotate, and the first pulley drives the second pulley to rotate through the synchronous belt, thereby driving the threaded rod 325 to rotate, so as to realize the conveying of the hydrogen storage material.

[0054] Further, the threaded rod 325 can pass through a sealing bearing arranged at the side wall of the hopper 31 to seal the hopper 31 and prevent the hydrogen storage material from leaking out.

[0055] As an example, as Figure 1 and Figure 6 The edge of the rotating disc 21 is further provided with a material pressing push rod 6, and the telescopic end of the material pressing push rod 6 can extend into the hydrogen storage bottle 4. The center of the material pressing push rod 6 is located at the position directly above the projection of the circumference where the center of the hydrogen storage bottle 4 is located, so that the material pressing push rod 6 can extend downward into the hydrogen storage bottle 6 to press the material. The material pressing push rod 6 is preferably arranged on the side opposite to the cutout 211. By arranging the material pressing push rod 6, after the feeding mechanism 3 feeds the hydrogen storage bottle 4, the rotating disc 21 is rotated to be opposite to the hydrogen storage bottle 4, the material pressing push rod 6 extends downward into the hydrogen storage bottle 4 to press the hydrogen storage material, until the value of the weighing sensor 11 changes obviously, the output end of the material pressing push rod 6 is withdrawn to above the hydrogen storage bottle 4, and the value of the weighing sensor 11 returns to the value before pressing the material. Specifically, the material pressing push rod 6 is preferably an electric push rod.

[0056] Specifically, the material pressing push rod 6 is installed on the rotating disc 21 through a mounting plate 61. The edge of the rotating disc 21 outwardly extends a limiting portion, the limiting portion is opposite to the hydrogen storage bottle 4, a through hole is formed in the limiting portion, and the telescopic end of the material pressing push rod 6 can extend into the hydrogen storage bottle 4 below through the through hole.
