Description

Technical Field

[0001] This application relates to the field of hydrogen storage device technology, and in particular to a pressure-stabilized hydrogen storage device. Background Technology

[0002] Hydrogen storage devices store hydrogen by compressing it under high pressure. Existing hydrogen storage devices consist of a tank, a filling structure, a gas outlet structure, a pressure sensor, and other components.

[0003] Hydrogen is flammable and explosive, and its pressure and storage conditions must be carefully controlled during storage. Existing hydrogen storage devices are prone to significant shaking during transportation or relocation if not securely fixed or handled improperly. This shaking causes changes in internal pressure, and excessive pressure can pose a safety hazard.

[0004] Therefore, this application proposes a pressure-stabilized hydrogen storage device. Utility Model Content

[0005] The purpose of this application is to address the technical problems identified in the background section by proposing a pressure-stabilized hydrogen storage device.

[0006] The technical solution of this application is as follows: A pressure-stabilized hydrogen storage device includes a tank body and tank protective pads fixedly connected to the side walls at both ends of the tank body. A protective seat is fixedly connected between the two tank protective pads. A movable component is provided at the bottom end of the protective seat, and a balancing component is also provided at the bottom end of the protective seat. The tank body is stably supported by the balancing component. An adjusting component is provided on the protective seat for adjusting the support state of the balancing component.

[0007] Preferably, the bottom end of the protective base is provided with a pair of grooves, and the movable component includes support blocks fixedly connected to both ends of the two grooves. A rotating rod is rotatably connected between the two pairs of support blocks, and the outer wall of the rotating rod protrudes to the lower end face of the protective base.

[0008] Preferably, the protective base has mounting grooves on both sides, and the balancing component includes two sliding cylinders fixedly connected to the inner wall of the mounting grooves. Sliding blocks are slidably connected inside the two sliding cylinders, and transmission rods are fixedly connected to the lower ends of the two sliding blocks. The bottom ends of the two transmission rods are jointly fixedly connected to a positioning support plate.

[0009] Limiting rings are fixedly connected to the lower inner walls of both slide cylinders, and the two limiting rings limit the movement of the two slides respectively.

[0010] Preferably, the adjusting component includes a threaded cylinder fixedly connected to the inner wall of the mounting groove, a threaded rod threadedly inserted into the threaded cylinder, and the lower end of the threaded rod being rotatably connected to the positioning support plate.

[0011] Preferably, an operating block is fixedly sleeved on the lower end side wall of the threaded rod, and the positioning support plate is pushed downward by rotating the threaded rod.

[0012] Preferably, one end of the tank is connected to a pipe, the side wall of which is equipped with a pressure sensor, a high-temperature automatic venting device, and a hydrogen filling port, and the end of the pipe is equipped with a hydrogen outlet pipe.

[0013] Compared with the prior art, this application has the following beneficial technical effects:

[0014] This application improves the safety performance of hydrogen storage by installing a movable part at the bottom of the protective base, which allows the tank to move horizontally when the tank is moved, thus stabilizing the tank's state during movement and preventing excessive fluctuations in internal pressure.

[0015] By installing a balancing component at the bottom of the protective base, the threaded rod can be rotated to move downwards when storing or transporting the tank. As the threaded rod moves downwards, it pushes the positioning support plates on both sides downwards, making them contact the ground or bottom support structure, thereby providing stable support for the tank and keeping its internal pressure within the normal range.

[0030] Example

[0031] like Figures 1-4As shown, this application proposes a pressure-stabilized hydrogen storage device, comprising a tank body 1 and tank protective pads 2 fixedly connected to the side walls at both ends of the tank body 1. One end of the tank body 1 is connected to a pipe, and the side wall of the pipe is equipped with a pressure sensor 4, a high-temperature automatic venting device 5, and a hydrogen filling port 6. The end of the pipe is equipped with a hydrogen outlet pipe 3. The two tank protective pads 2 provide protection for the tank body 1. A protective seat 7 is fixedly connected between the two tank protective pads 2. A movable component 11 is provided at the bottom of the protective seat 7, allowing for smooth movement of the tank body 1 and preventing excessive pressure changes during movement. A balancing component 8 is also provided at the bottom of the protective seat 7, providing stable support for the tank body 1. An adjusting component 9 is provided on the protective seat 7 to adjust the support state of the balancing component 8, allowing for flexible adjustment of the balancing component 8 according to storage or movement requirements.

[0032] Specifically, the bottom end of the protective base 7 is provided with a pair of grooves. The movable component 11 includes support blocks 111 fixedly connected to both ends of the two grooves. Rotary rollers 112 are rotatably connected between the two pairs of support blocks 111. The outer wall of the rotary rollers 112 protrudes to the lower end face of the protective base 7. When it is necessary to move the tank 1, the two rotary rollers 112 contact the ground, which can smoothly move the tank 1 to the designated location and move it easily.

[0033] Furthermore, mounting slots are provided on both sides of the protective base 7. The balancing component 8 includes two sliding cylinders 801 fixedly connected to the inner wall of the mounting slots (one pair of sliding cylinders 801 is provided in each pair of mounting slots). Sliding blocks 802 are slidably connected in the two sliding cylinders 801 on the same side. The lower ends of the two sliding blocks 802 are fixedly connected to transmission rods 803. The bottom ends of the two transmission rods 803 are jointly fixedly connected to positioning support plates 805. When the two positioning support plates 805 are in contact with the ground, they can prevent the two rotating rollers 112 from easily rotating under the contact of external force. Among them, the lower inner walls of the two sliding cylinders 801 are fixedly connected to limit rings 804. The two limit rings 804 limit the two sliding blocks 802 respectively, preventing the sliding blocks 802 from detaching from the sliding cylinders 801.

[0034] The adjusting component 9 includes a threaded cylinder 901 fixedly connected to the inner walls of two mounting slots. A threaded rod 902 is threadedly inserted into the threaded cylinder 901, and the lower end of the threaded rod 902 is rotatably connected to a positioning support plate 805 on the same side. An operating block 903 is fixedly sleeved on the lower side wall of the threaded rod 902. Rotating the threaded rod 902 pushes the positioning support plate 805 downward. In this application, since the two sliders 802 are limited and set within the two sliders 801, the threaded rod 902 will not disengage from the threaded cylinder 901 when it is rotated.

[0035] The working principle of this embodiment is as follows: hydrogen is filled into the interior of the tank 1 through the hydrogen outlet pipe 3 for hydrogen storage. A protective seat 7 is set at the bottom of the tank 1, and a movable part 11 is set at the lower end of the protective seat 7. The outer diameter of the two rotating rollers 112 protrudes below the protective seat 7. When the tank 1 needs to be moved, the two rotating rollers 112 contact the ground, and the tank 1 can be pushed to the designated location in a balanced and easy manner.

[0036] When it is necessary to store or transport the tank 1, the two threaded rods 902 can be rotated by holding the operating block 903 in sequence (or operated with the help of external tools). When the threaded rods 902 are rotated, they will move downwards, which will push the corresponding positioning support plates 805 downwards until both positioning support plates 805 on both sides are in contact with the ground or the load plate of the transport vehicle, thereby completing the balanced support of the tank 1. If it is for storage, it can meet the requirements of stable storage. If it is for transportation, it can be further fixed according to the requirements.

[0037] When it is necessary to move tank 1 again, rotate the two threaded rods 902 in reverse order to insert them into the threaded cylinder 901, thereby moving the two positioning support plates 805 upward. This restores the two rotating rollers 112 to their independent support state, making it easier to move tank 1.

[0038] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
