Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen busbars, and more specifically, to a hydrogen busbar protection device. Background Art

[0002] A hydrogen bus refers to a bus device for gathering hydrogen. The bus structure is simple, usually connecting multiple pipes and valve bodies, and requires auxiliary devices to fix. Existing hydrogen bus fixing devices are usually simple metal plate clamps or fixed by ropes, usually with auxiliary bolts or welding, which is cumbersome to operate and inconvenient after fixing.

[0003] After searching, a Chinese patent with announcement number CN214789451U discloses a hydrogen bus fixing device. Through the setting of the device main body and the matching auxiliary structure, it can provide a structure for clamping on both sides. Different from the traditional bolt fixing, it is fixed by a clamping rod, and the clamping rod can be pressed and retracted. The clamping rod of the rope and the baffle that can be limited can form a restricting structure. The auxiliary device main body can form a circular clamping structure with a stable clamping effect and convenient disassembly. It is more convenient and efficient during installation and disassembly.

[0004] When the above-mentioned fixing device is in use, the clamping rods at both ends are pressed until the second baffle and the middle sleeve are fitted together, and the whole is clamped into the first connecting groove and the second connecting groove. It is fixed by clamping, which is easy to shake in the event of a collision, affecting the stability of the hydrogen bus. Utility Model Content

[0027] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Refer to the instruction manual Figure 1-6The hydrogen bus protection device of this embodiment includes a protection frame 1 and a hydrogen bus body 2, and the hydrogen bus body 2 is located inside the protection frame 1. A fixing component 3 is provided inside the protection frame 1. The fixing component 3 includes a positive and negative screw rod 301, four side plates 302, four connecting frames 303, two horizontal plates 304 and a limiting rod 305. The top and bottom ends of the positive and negative screw rods 301 are movably connected to the protection frame 1 through bearings, and the top and bottom ends of the limiting rod 305 are fixedly connected to the protection frame 1. The four side plates 302 are movably mounted on the positive and negative screw rods 301 and the limiting rod 305, respectively, and one side of the four side plates 302 is fixedly connected to the four connecting frames 303, respectively, and one side of the four connecting frames 303 is fixedly connected to the two horizontal plates 304, respectively.

[0029] Furthermore, the two facing sides of the two horizontal plates 304 are fixedly connected with the first gaskets 306, and the facing sides of the two first gaskets 306 are in contact with the hydrogen bus body 2. A handle 307 is movably provided on one side of the hydrogen bus body 2, and the handle 307 is fixedly sleeved on the forward and reverse screw rods 301.

[0030] Furthermore, two limit assemblies 4 are provided on two of the connection frames 303, and the four limit assemblies 4 each include a slide bar 401, a spring 402, a limit plate 403 and two clamping plates 404, one end of the four slide bars 401 is respectively fixedly connected to two of the connection frames 303, and the other ends of the four slide bars 401 respectively penetrate the four springs 402 and the four limit plates 403, one side of the plurality of clamping plates 404 is respectively fixedly connected to the four limit plates 403, and the other sides of the four clamping plates 404 extend into two of the connection frames 303, one side top of the four limit plates 403 is fixedly connected to a second gasket 405, and one side of the four second gaskets 405 is in contact with the hydrogen bus body 2.

[0031] Among them, when the hydrogen bus body 2 is located on the top of one of the horizontal plates 304, the hydrogen bus body 2 squeezes the four limit plates 403, thereby driving the four springs 402 to compress. When the hydrogen bus body 2 is released, the four limit plates 403 rebound and drive the four limit plates 403 to limit the hydrogen bus body 2. At the same time, the four second gaskets 405 can improve the firmness between the four limit plates 403 and the hydrogen bus body 2. The limit plates 403 drive the two clamping plates 404 to move in the connecting frame 303, which can prevent the limit plates 403 from deflecting when moving horizontally.

The structure is simple and the safety performance is high.

[0034] The method of using this embodiment is:

[0035] When in use, the staff puts the hydrogen bus body 2 into the protective frame 1, and the hydrogen bus body 2 is located between the two cross plates 304, and the hydrogen bus body 2 is protected by the protective frame 1, and then the handle 307 is turned to drive the forward and reverse screw rods 301 to rotate. Since two of the side plates 302 are threadedly connected to the forward and reverse screw rods 301, and the other two side plates 302 cooperate with the limit rods 305 to limit the rotation of the two cross plates 304, the forward and reverse screw rods 301 can drive the two cross plates 304 to move toward each other, and the hydrogen bus body 2 is squeezed and fixed by the two cross plates 304. The operation is simple, the hydrogen bus body 2 is not easy to shake, and the stability of the hydrogen bus body 2 is effectively improved. At the same time, the two first gaskets 306 can further improve the firmness between the hydrogen bus body 2 and the two cross plates 304.
