Traditional enclosure structures are usually rigidly connected to the workbench, making disassembly and assembly difficult, thus affecting cleaning and maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-splash device for spraying hydrogen energy catalyst carriers, comprising a support column, a base connected below the support column, a platform connected above the support column, multiple guide grooves on the support column, a motor fixedly installed inside the base, a threaded rod connected to the output shaft of the motor, a cross block threadedly installed on the threaded rod, a fixing ring connected to the cross block, four support plates connected to the fixing ring in a centrally symmetrical manner, a connecting block connected to one side of the support plate, and a fence installed on the support plate through the connecting block; The support plate has a limiting groove, and an inner ring and an outer ring are slidably connected in the limiting groove. One end of the support plate has a cavity, and a T-shaped rod is slidably connected in the cavity. A spring is sleeved on the T-shaped rod. One end of the T-shaped rod is connected to an L-shaped rod, and the other end of the T-shaped rod is connected to an insert rod. A slotted plate is connected between the inner ring and the outer ring. A connecting groove is provided below the fence, and an insertion hole is provided on the groove wall.

[0006] As a further embodiment of this utility model: the threaded rod is rotatably connected to the support column through a bearing, and the cross block slides in the guide groove and contacts the groove wall.

[0007] As a further embodiment of this utility model: the base is provided with an installation groove, the fixing ring is sleeved on the support column and slidably connected to the support column, and a corrugated cover is connected between the base and the fixing ring, and the corrugated cover is sleeved on the support column.

[0008] As a further embodiment of this utility model: four slotted plates are obliquely connected between the inner ring and the outer ring in a centrally symmetrical manner. The inner ring is provided with threaded holes. A fixing bolt is threadedly connected to the bottom of a support plate on the fixing ring. The fixing bolt passes through the support plate and is threadedly connected to the threaded hole.

[0009] As a further embodiment of this utility model: both the inner ring and the outer ring are in close contact with the wall of the limiting groove, and a sliding groove is provided on the upper wall of the limiting groove, and one end of the L-shaped rod passes through the sliding groove and slides in the groove of the slotted plate.

[0010] As a further embodiment of this utility model: the connecting block is inserted into the connecting groove, one end of the spring is connected to the inner wall of the support plate, the other end of the spring is connected to the top of the T-shaped rod, and the insertion rod passes through the connecting block and is inserted into the insertion hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This anti-splash device for spraying hydrogen energy catalyst carriers comprises a slotted plate, a sliding groove, an L-shaped rod, a T-shaped rod, an insert rod, an insertion hole, a connecting block, and a connecting groove. During assembly, the connecting block is pushed into the connecting groove. Then, by pushing the outer ring, the outer and inner rings gradually rotate around the axis of the support column. During this process, the inclined slotted plate pushes the L-shaped rod through the groove wall, causing the T-shaped rod to slide within the support plate and compress the spring. This allows the insert rod to pass through the connecting block and be inserted into the insertion hole. At this point, the end of the L-shaped rod abuts against the groove wall at one end of the slotted plate, and the threaded hole aligns with the fixing bolt. Fixing is achieved by tightening the fixing bolt and threading the threaded hole. The operation is simple; multiple fixing and limiting points can be completed simply by rotating the outer ring, making it easy for workers to disassemble and maintain.

[0012] 2. This anti-splash device for spraying hydrogen energy catalyst carriers consists of a threaded rod, a cross block, a guide groove, a support plate, and a barrier. By starting a motor and rotating the threaded rod, the cross block slides along the threaded rod in the guide groove, thereby moving the fixing ring and the support plate together. This causes the barrier to exceed the height of the carrier platform, thus protecting the platform and preventing the catalyst from splashing everywhere and contaminating the working environment outside the platform. The height of the barrier is adjustable to meet actual usage requirements. Attached Figure Description

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figure 1-5 As shown, this utility model provides a technical solution: an anti-splash device for spraying hydrogen energy catalyst carriers, including a support column 1, a base 2 connected below the support column 1, a platform 3 connected above the support column 1, multiple guide grooves 4 opened on the support column 1, a motor 5 fixedly installed in the base 2, a threaded rod 6 connected to the output shaft of the motor 5, a cross block 7 threadedly installed on the threaded rod 6, the threaded rod 6 being rotatably connected to the support column 1 through a bearing, the cross block 7 sliding in the guide groove 4 and contacting the groove wall of the guide groove 4, the groove wall of the guide groove 4 limiting and guiding the cross block 7, preventing the cross block 7 from rotating and tilting during lifting and moving, and promoting the smooth movement of the fence 11.

[0016] A fixing ring 8 is connected to the cross block 7, and an installation groove 22 is provided on the base 2. The fixing ring 8 is sleeved on the support column 1 and slidably connected to the support column 1. A corrugated cover 23 is connected between the base 2 and the fixing ring 8, and the corrugated cover 23 is sleeved on the support column 1. When the enclosure 11 moves upward, the corrugated cover 23 will be stretched, thereby blocking the guide groove 4 and preventing impurities from entering the guide groove 4 and damaging the threaded rod 6. When the enclosure 11 moves downward, it will be level with the platform 3 and block the support column 1.

[0017] Four support plates 9 are connected to the fixed ring 8 in a centrally symmetrical manner. A connecting block 10 is connected to one side of the support plate 9. A guardrail 11 is installed on the support plate 9 through the connecting block 10. A limiting groove 12 is opened on the support plate 9. An inner ring 13 and an outer ring 14 are slidably connected in the limiting groove 12. The inner ring 13 and the outer ring 14 are in close contact with the groove wall of the limiting groove 12. A sliding groove 26 is opened on the groove wall above the limiting groove 12. One end of the L-shaped rod 17 passes through the sliding groove 26 and slides in the groove of the slotted plate 19. Through the contact between the inner ring 13 and the outer ring 14 and the groove wall of the limiting groove 12, the inner ring 13 and the outer ring 14 can be restricted to avoid deviation or up and down movement when pushed and rotated.

[0018] The support plate 9 has a cavity at one end, and a T-shaped rod 15 is slidably connected inside the cavity. A spring 16 is sleeved on the T-shaped rod 15. One end of the T-shaped rod 15 is connected to an L-shaped rod 17, and the other end of the T-shaped rod 15 is connected to an insert rod 18. A slotted plate 19 is connected between the inner ring 13 and the outer ring 14. There are four slotted plates 19 in total, which are obliquely connected between the inner ring 13 and the outer ring 14 in a centrally symmetrical manner. A threaded hole 24 is opened on the inner ring 13. A fixing bolt 25 is threadedly connected to the bottom of one of the support plates 9 on the fixing ring 8. The fixing bolt 25 passes through the support plate 9 and is threadedly connected to the threaded hole 24. By simply turning a single fixing bolt 25, the fixing bolt 25 is threadedly connected to the threaded hole 24, thereby fixing the inner ring 13 and the outer ring 14 and preventing accidental rotation. The operation is simple.

[0019] A connecting groove 20 is provided below the fence 11, and an insertion hole 21 is provided on the wall of the connecting groove 20. The connecting block 10 is inserted into the connecting groove 20. One end of the spring 16 is connected to the inner wall of the support plate 9, and the other end of the spring 16 is connected to the top of the T-shaped rod 15. The insertion rod 18 passes through the connecting block 10 and is inserted into the insertion hole 21. By connecting the connecting block 10 and the connecting groove 20, it is convenient for workers to quickly install the fence 11 on the support plate 9. The rebound of the spring 16 can facilitate the T-shaped rod 15 and the insertion rod 18 to reset when they are loosened.

[0020] The working principle of this utility model is as follows: By pushing the connecting block 10 into the connecting groove 20, the insertion hole 21 will be aligned with the insertion rod 18. Then, by pushing the outer ring 14, the outer ring 14 and the inner ring 13 will gradually rotate around the axis of the support column 1. During this process, the inclined slotted plate 19 will push the L-shaped rod 17 through the groove wall, causing the L-shaped rod 17 to push the T-shaped rod 15 along the slide groove 26, causing the T-shaped rod 15 to compress the spring 16, and causing the insertion rod 18 to pass through the connecting block 10 and be inserted into the insertion hole 21, thereby completing the installation and fixing of the enclosure 11. Then, the motor 5 is started to rotate the threaded rod 6, causing the cross block 7 to slide along the threaded rod 6 in the guide groove 4, thereby driving the fixing ring 8 and the support plate 9, causing the height of the enclosure 11 to exceed the platform 3, thereby enclosing the platform 3 and preventing the catalyst from splashing everywhere and contaminating the working environment outside the platform 3.
