Description

Technical Field

[0001] This utility model relates to the field of hydrogen storage technology, and in particular to an intelligent hydrogen storage device. Background Technology

[0002] Hydrogen, as a clean energy carrier, is increasingly widely used in industry, energy, and transportation. However, the storage and management of hydrogen still face many technical challenges. Currently, hydrogen is typically stored in high-pressure cylinders before use, and the storage and management of these cylinders must adhere to strict safety regulations to ensure the stability and reliability of the storage process.

[0003] According to current hydrogen cylinder storage regulations, cylinders must be stored in a dry, well-ventilated dedicated warehouse, and must be stored upright with a certain distance between them to avoid the risk of collision or tipping. Although existing technology can meet basic hydrogen storage requirements, the following significant problems still exist:

[0004] First, when gas cylinders are placed directly on the warehouse floor, they lack effective fixing devices and are easily tipped over due to external forces (such as vibration or collision). Furthermore, traditional gas cylinder storage methods often occupy a large amount of space and are difficult to achieve dense and automated management. Second, the storage and retrieval of gas cylinders mostly rely on manual handling, which is not only inefficient, but also prone to damage or leakage risks due to human error during frequent operations. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, such as unstable hydrogen cylinder storage, low efficiency of manual operation and insufficient safety, this utility model provides an intelligent hydrogen storage device, thereby improving the reliability, automation level and space utilization of hydrogen storage.

[0006] The technical solution of this utility model is: an intelligent hydrogen storage device, comprising: a hydrogen storage rack for storing hydrogen cylinders, having a rectangular frame, with multiple rows of movable plates at the bottom of the rectangular frame, multiple vertical slots on the sides of the rectangular frame that movably cooperate with the movable plates, and a flip-type rectangular baffle at the top of the rectangular frame; a lifting mechanism, including a hydrogen storage rack placement platform, with multiple rows of reserved slots on the top surface of the hydrogen storage rack placement platform that adapt to the movable plates, and lifting cylinders respectively installed in the reserved slots; and a gripping mechanism, including a movable gantry frame, with an X-moving unit installed on the gantry frame, a Y-moving unit installed at the movable end of the X-moving unit, a Z-moving unit installed at the movable end of the Y-moving unit, and a mechanical gripper installed on the Z-moving unit.

[0007] Furthermore, the rectangular frame includes a frame body, one end of which is hinged to the rectangular frame via a horizontal axis, and the other end is provided with a support foot. A rubber pad is glued to the bottom of the support foot. Thin rods parallel to the movable plate are provided at opposite ends on the upper side of the frame body, and the thin rods are rotatably connected to the frame body.

[0008] Furthermore, the vertical groove is provided with a reset assembly, including a vertical rod and a spring. A vertical through hole is opened at the top of the vertical groove. The vertical rod is movably disposed in the vertical through hole. The lower end of the vertical rod is connected to a movable plate. The spring is sleeved on the vertical rod. The upper end of the spring abuts against the top of the vertical groove, and the lower end abuts against the movable plate.

[0009] Furthermore, lifting rings are provided around the upper side of the rectangular frame.

[0010] Furthermore, the bottom of the rectangular frame is provided with multiple positioning pins, and the top surface of the hydrogen storage rack placement platform is provided with multiple positioning holes that are adapted to the positioning pins.

[0011] The beneficial effects are:

[0012] 1. This utility model uses a rectangular frame and a movable plate to make hydrogen cylinders stand upright stably, avoiding the risk of tipping over. The lifting cylinder can precisely control the height of the movable plate, which facilitates the gripping mechanism and improves the storage and retrieval efficiency of the cylinders. In addition, the X / Y / Z three-axis moving unit of the gripping mechanism can achieve precise positioning, and the mechanical gripper can stably grip the cylinders, reducing the risk of manual operation.

[0013] 2. The flip-type rectangular baffle of this utility model can restrict the movement of the top of the gas cylinder after it is stored, preventing the gas cylinder from falling off during transportation or vibration. At the same time, the thin rod can further restrict the displacement of the gas cylinder and reduce wear between the gas cylinder and the rectangular frame or rectangular baffle during handling.

[0014] 3. The spring of this utility model provides elastic support, so that the movable plate can automatically return to its original position after being subjected to force, thereby improving the durability of the device.

[0015] 4. The lifting ring of this utility model can be used with forklifts or cranes to facilitate the movement and deployment of the entire hydrogen storage rack.

[0016] 5. The pin and positioning hole of this utility model cooperate to ensure that the hydrogen storage rack can be quickly placed in the corresponding position on the placement platform, and can also prevent the hydrogen storage rack from shifting or sliding. After the pin is fixed, the hydrogen storage rack is not easily affected by external forces, thus improving the stability of the overall structure. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-5 As shown, this embodiment provides an intelligent hydrogen storage device suitable for the efficient and safe storage and automated management of hydrogen cylinders. The device mainly includes a hydrogen storage rack 10, a lifting mechanism 20, and a gripping mechanism 30, and integrates remote control functionality. It can be deployed in industrial environments to achieve stable storage, automated retrieval, and remote inspection of hydrogen cylinders.

[0025] For details, please refer to Figure 2 and Figure 3The hydrogen storage rack 10 is the core storage unit of the device, specifically including: a rectangular frame 11, which is welded from high-strength steel, with multiple rows of movable plates 12 at the bottom. The movable plates 12 can slide up and down through vertical grooves 13 on the side of the rectangular frame 11 to support the hydrogen cylinder. A flip-type rectangular support frame 14 is hinged to the top of the frame and includes: a frame body 141, which is hinged to the frame 11 through a horizontal axis 142 and can be flipped around the horizontal axis 142. The purpose of setting the frame body 141 is to limit the displacement of the top of the gas cylinder when the gas cylinder is placed behind the rectangular frame 11, thereby providing stability. In addition, a support foot 143 is provided at the bottom of the end of the frame body 141 opposite to the horizontal axis 142. The end of the support foot 143 is glued with an anti-slip rubber pad, and the end with the support foot 143 rests on the top of the rectangular frame 11. The support foot 143 provides support and ensures that the frame body 141 is stable after being flipped.

[0026] Furthermore, the movable plate 12 has slider structures at both ends, which are embedded in and slidably connected to the vertical groove 13. In addition, the surface of the movable plate 12 is provided with anti-slip texture to further improve the stability of the gas cylinder placement.

[0027] In addition, a rotatable thin rod 144 is provided at each of the two opposite ends on the upper side of the frame body 141 (the end with the support foot 143 and the end connected to the horizontal axis 142). The thin rod 144 is set parallel to the movable plate 12. The function of the thin rod 144 is to prevent direct contact when the hydrogen cylinder is picked up or put down, as the cylinder body may shake and come into contact with the rectangular frame 11 or the frame body 141, causing friction damage to the cylinder body. The rotatable thin rod 144 can prevent direct contact.

[0028] Furthermore, such as Figure 2 As shown, the device also includes lifting rings 50, which are distributed at the four corners of the frame and are made of steel wire or steel bars. The lifting rings 50 are set in the upper half of the rectangular frame 11 to facilitate lifting by cranes and lifting equipment. This makes it easy to replace the entire rectangular frame 11. The application scenario is when all the hydrogen cylinders in the entire frame are used up, refilled, and then put back. At this time, the entire rectangular frame 11 containing the gas cylinders is lifted by a crane and placed on top of the lifting mechanism 20.

[0029] refer to Figure 4The lifting mechanism 20 is used to assist in the storage and retrieval of gas cylinders. Specifically, it includes a hydrogen storage rack placement platform 21. The top surface of the hydrogen storage rack 10 placement platform has multiple rows of reserved slots 22 that are adapted to the movable plate 12. Each reserved slot 22 is equipped with a lifting cylinder 23. In this embodiment, the hydrogen storage rack placement platform 21 is buried underground in the hydrogen storage warehouse and is formed by concrete pouring. At least one lifting cylinder 23 is provided at each end of the reserved slot 22, and the lifting cylinders 23 in the same reserved slot 22 are connected to the same control device, that is, they can be lifted or retracted at the same time.

[0030] The reserved slot 22 and the movable plate 12 are positioned in a corresponding manner. The lifting cylinder 23 in the same reserved slot 22 will act on a movable plate 12, thereby indirectly lifting the hydrogen cylinder by lifting the movable plate 12. Figure 4 In the middle, the first row of cylinders is lifted up. The rectangular frame 11 used in this embodiment can hold a total of 16 hydrogen cylinders in a 4×4 configuration, and there are 4 rows of movable plates 12. In addition, in order for the movable plates 12 to be able to be smoothly reset after the cylinders are removed, a reset component 40 is provided in the vertical groove 13.

[0031] Specifically, the reset assembly 40 includes a vertical rod 41 and a spring 42. A vertical through hole is formed at the top of the vertical groove 13, and the vertical rod 41 is movably disposed in the vertical through hole. The lower end of the vertical rod 41 is connected to the movable plate 12. The spring 42 is sleeved on the vertical rod 41, with its upper end abutting against the top of the vertical groove 13 and its lower end abutting against the movable plate 12. The spring 42 provides elastic support, allowing the movable plate 12 to automatically reset after being compressed (such as when a gas cylinder is placed), and also has a buffering and shock absorption function.

[0032] In a preferred embodiment, such as Figure 4 As shown, the bottom of the rectangular frame 11 is provided with multiple positioning pins 60. In this embodiment, four positioning pins 60 are provided, located at the four bottom corners of the rectangular frame 11. The top surface of the corresponding hydrogen storage rack 10 placement platform is provided with multiple positioning holes 70 that are adapted to the positioning pins 60. The positioning pins 60 cooperate with the positioning holes 70 of the placement platform to achieve rapid and accurate positioning. This not only makes the rectangular frame 11 more stable but also allows for quick alignment of the lifting cylinder 23 with the movable plate 12. To further improve the accuracy of this device, a laser locator is added to the hydrogen storage rack placement platform 21, and a laser receiving target is set at the bottom of the hydrogen storage rack 10, thereby enabling accurate feedback of position signals.

[0033] In a preferred embodiment, such as Figure 5As shown, the gripping mechanism 30 is a fully automated operating unit, including: a mobile gantry 31 that spans the hydrogen storage rack 10, covering all storage positions; the mobile gantry 31 integrates a three-axis motion system: composed of X, Y, and Z motion units 32, 33, and 34. The movable end of the X motion unit 32 is equipped with a Y motion unit 33, and the movable end of the Y motion unit 33 is equipped with a Z motion unit 34. The Z motion unit 34 is equipped with a mechanical gripper 35, driving the mechanical gripper 35 to achieve precise three-dimensional positioning; specifically in this embodiment, the X, Y, and Z motion units 32, 33, and 34 are all lead screw slides, the mechanical gripper 35 adopts an adaptive gripping design, and has a built-in pressure feedback system to avoid excessive gripping force causing deformation of the gas cylinder. The surface of the mechanical gripper 35 is covered with anti-static material to eliminate the risk of electrostatic sparks in the hydrogen environment. The control system for controlling the mechanical gripper 35 can be set up in the control room and operated remotely.

[0034] Gas cylinder retrieval process:

[0035] 1. Staff in the control room issue instructions to retrieve the gas cylinders;

[0036] 2. By sending a command through the control terminal, the lifting mechanism 20 adjusts the height of the movable plate 12 to lift the gas cylinder;

[0037] 3. The gripping mechanism 30 automatically completes the storage and retrieval of gas cylinders;

[0038] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
