[0036] As a technical optimization solution of the present invention, the cleaning mechanism includes a slide groove 14 opened on the outer wall of the side close to the two rotating rods 5, and the two slide grooves 14 are both installed with sliders 15, and the two sliders 15 are installed with a movable plate 6 at one end away from the slide groove 14. Linear motors are preset inside the two slide grooves 14, and the two linear motors can drive the two sliders 15 to move up and down inside the corresponding slide grooves 14, and drive the movable plate 6 to move up and down together.

[0037] As a technical optimization solution of the present invention, the interior of the two movable plates 6 is provided with a semicircular notch adapted to the outer wall of the device body 2, and the arc-shaped inner walls of the two semicircular notches are installed with cleaning pads 19. When the two movable plates 6 move up and down together, the two cleaning pads 19 are driven to clean the surface of the device body 2.

A third driving device is preset inside the two moving plates 6, and the output ends of the two third driving devices are respectively connected to one end of the two screw rods 18, so that the two screw rods 18 can be driven to rotate inside the corresponding second grooves 17. During the rotation process, the two screw rods 18 can drive the corresponding second moving blocks 16 to move back and forth on the top of the moving plate 6.

[0039] As a technical optimization solution of the present invention, the two second moving blocks 16 are rotatably mounted on one end thereof close to each other with a rotating plate 7, a soft pad 20 matching the semicircular notch is mounted on the outer wall of the rotating plate 7 close to the moving plate 6, and an arc groove 21 matching the outer wall of the device body 2 is provided on the outer wall of the soft pad 20 away from the rotating plate 7. A first driving motor is preset inside one of the second moving blocks 16, and the output end of the first driving motor is connected to the rotating part of the rotating plate 7, so as to drive the rotating plate 7 to rotate and adjust on the top of the moving plate 6.

[0040] As a technical optimization scheme of the present invention, the protective mechanism includes a rotating seat 23 rotatably installed on the top of one of the rotating rods 5, a first electromagnet 25 is installed on the top of one of the rotating rods 5, a metal plate 24 magnetically attracted to the first electromagnet 25 is installed on the top of the rotating seat 23, and a second electromagnet 26 is installed on the outer wall of one side of one of the rotating rods 5 close to the rotating seat 23, and the second electromagnet 26 is magnetically attracted to the outer wall of the rotating seat 23 when energized. A second drive motor is preset on the outer wall of one side of one of the rotating rods 5, and the output end of the second drive motor is connected to the rotating part of the rotating seat 23, so that the rotating seat 23 can be driven to rotate and adjust on the outer wall of one side of one of the rotating rods 5; after the rotating seat 23 rotates upward by 90 degrees, it drives the metal plate 24 to contact the first electromagnet 25, and after the first electromagnet 25 is energized, the first electromagnet 25 can be magnetically attracted to the metal plate 24; when the rotating seat 23 is in the original vertical state, the second electromagnet 26 is controlled to be energized, which can drive the second electromagnet 26 to be magnetically fixed to the rotating seat 23, so that the rotating seat 23 rotates to a horizontal or vertical state, which can be assisted by the corresponding first electromagnet 25 and second electromagnet 26 for magnetic fixation.

[0041] As a technical optimization solution of the present invention, a winding roller 27 is rotatably installed inside the rotating seat 23, and the outer wall of the winding roller 27 is rolled up with the blackout curtain 8. A third driving motor is preset on the outer wall of one side of the rotating seat 23, and the output end of the third driving motor is connected to the rotating part of the winding roller 27, which can drive the winding roller 27 to rotate and adjust inside the rotating seat 23 to roll up or unfold the blackout curtain 8.

[0042] As a technical optimization solution of the present invention, a fixing plate 28 is installed at one end of the shielding curtain 8 away from the winding roller 27, and two connecting seats 29 and a handle 30 are installed on the outer wall of the fixing plate 28 away from the shielding curtain 8. The outer walls of the plurality of rotating rods 5 are provided with connecting holes 22 used in conjunction with the connecting seats 29. After the shielding curtain 8 is unfolded from the surface of the winding roller 27, the handle 30 is manually pulled to drive the fixing plate 28 to unfold the shielding curtain 8 along the manual pulling direction, and the fixing plate 28 is threadedly installed in the connecting hole 22 on the outer wall of one of the rotating rods 5 by means of two corresponding screws through the two connecting seats 29, so that the unfolded shielding curtain 8 can be limited and fixed.

[0043] In the present invention, when the user uses the device and transports the prepared hydrogen to the inside of the device body 2 for storage, as more and more hydrogen is stored in the device body 2, the device body 2 itself will vibrate to a certain extent. At this time, with the help of multiple shock-absorbing springs 9 arranged between the mounting plate 3 and the base 1 and the damping rod 10, the vibration exerted on the device body 2 can be buffered and released, thereby avoiding the problem that the device body 2 continues to vibrate during use, resulting in reduced stability and reliability of the device body 2, thereby improving the protection of the device body 2.

[0044] Furthermore, during normal use of the device body 2, the two movable plates 6 located at the top of the device body 2 cooperate with the rotating plate 7 to provide a shielding and protective effect on the top of the device body 2, ensuring that the device body 2 will not be affected by the danger of falling objects from above, thereby improving the safety of the device body 2 when in use.

[0045] If other operations need to be performed near the device body 2, in order to avoid affecting the normal use of the device body 2, the winding roller 27 can be controlled to rotate inside the rotating seat 23, driving the shielding curtain 8 to unfold from the surface of the winding roller 27, and the handle 30 can be manually pulled to pull the shielding curtain 8 and surround the device body 2. At this time, the other three rotating rods 5 can be used as support columns to facilitate auxiliary support for the shielding curtain 8 surrounding the device body 2. Finally, the handle 30 is manually pulled to one side of one of the rotating rods 5, so that the positions of the two connecting seats 29 correspond to the positions of the two connecting holes 22 opened on the outer wall of one side of one of the rotating rods 5, and the fixing plate 28 can be limited and fixed on one of the rotating rods 5 with the help of corresponding screws, so as to achieve the effect of limiting and fixing the unfolded shielding curtain 8, thereby reducing the adverse effects of other operations in the surrounding area on the use of the device body 2 and improving the protection effect of the device body 2.

[0046] Before the device body 2 is put into use, it is only temporarily placed in a certain location for temporary storage. For example, the device body 2 is located outdoors or under the eaves. The two movable plates 6 cooperate with the rotating plate 7 to have a protective effect on the top of the device body 2, and there is no relevant shielding component in front of the device body 2. If the above steps are repeated to directly surround the shielding curtain 8 around the device body 2, the ventilation effect of the device body 2 will be poor, and it is easy to condense or corrode on the surface during storage, which will reduce the service life of the device body 2. At this time, you can refer to Fig. 9 As shown, the outer wall of one side of the rotating seat 23 is controlled to rotate upward to a horizontal state, driving the metal plate 24 set on the top of the rotating seat 23 to rotate to a state abutting against the first electromagnet 25. By controlling the first electromagnet 25 to be energized to generate magnetism, the metal plate 24 can be tightly magnetically fixed to the first electromagnet 25, which has an auxiliary fixing effect on the rotating seat 23 that rotates to a horizontal state. At this time, the winding roller 27 is controlled to rotate to drive the shielding curtain 8 to unfold. After manually pulling the handle 30, the shielding curtain 8 is unfolded in a horizontal state on the front side of the device body 2, and the unfolded shielding curtain 8 is limited and fixed at one end away from the winding roller 27. At this time, the shielding curtain 8 located in the front side of the device body 2 in a horizontal unfolded state can block the sunlight in the external environment, and has a sunshade and shade effect on the device body 2, ensuring that the device body 2 is well ventilated during storage. It can also prevent the device body 2 from being exposed to sunlight for a long time, which will bring adverse effects on subsequent use.

[0047] Furthermore, when transporting a plurality of device bodies 2 and bases 1, Figure 8As shown, after one of the device bodies 2 and the base 1 is placed inside the transport equipment, the two matching rotating rods 5 are controlled to rotate downward in a direction away from the device body 2 to a horizontal state, and then the other subsequent device bodies 2 and bases 1 are neatly placed on top of the two matching rotating rods 5 to ensure that the other device bodies 2 and bases 1 are relatively stable during transportation, and then the two sliders 15 are controlled to move in the corresponding sliding grooves 14 in the direction of approaching the device body 2, driving the two moving plates 6 and the rotating plate 7 to also move in the direction of approaching the device body 2, so that the soft pads 20 set on the outer walls of one side of the two rotating plates 7 can be close to them. The outer wall of the device body 2 is in contact with the two rotating rods 5, and with the help of two movable plates 6 and a rotating plate 7, the other device bodies 2 and the base 1 placed on the top of the two rotating rods 5 can be auxiliary limited and fixed, and the winding rollers 27 in the device bodies 2 and the base 1 placed on the top of the two rotating rods 5 can be controlled to rotate, thereby driving the corresponding shielding curtains 8 to unfold. At this time, the staff can pull the handle 30 to surround the shielding curtains 8 around the surfaces of the multiple device bodies 2 placed on the top of the two rotating rods 5, and further limit the placement of the multiple device bodies 2 on the top of the two rotating rods 5, thereby ensuring the safety and stability of the multiple device bodies 2 during transportation, thereby further improving the protection of the device bodies 2.

[0048] After the device body 2 is put into use, dust and other impurities are easily attached to the surface of the device body 2 because the device body 2 is exposed to the use environment for a long time. In order to reduce the adverse effects of dust and other impurities on the use of the device body 2, the dust and other impurities on the surface of the device body 2 can be cleaned when it is necessary, such as Figure 7 As shown, the two rotating plates 7 can be controlled to rotate upward together, so that the semicircular notches set on the side close to the two movable plates 6 are exposed. Since the two semicircular notches are adapted to the outer wall of the device body 2, the corresponding two sliders 15 move downward in the slide groove 14, driving the two movable plates 6 to move downward together, so that the cleaning pads 19 set on the arc-shaped inner walls of the two semicircular notches can rub closely with the outer wall of the device body 2, and dust and other impurities attached to the surface of the device body 2 can be automatically cleaned and removed without manual cleaning.

[0049] When it is necessary to disassemble and separate the device body 2 and the mounting plate 3 and replace the new device body 2, after manually removing the multiple bolts between the bottom plate 4 and the mounting plate 3, the above-mentioned steps of cleaning the surface of the device body 2 with the help of the two movable plates 6 can be repeated, so that the two movable plates 6 are moved downward to the central position close to the device body 2, and the two double-headed screws 12 are controlled to drive the corresponding two first movable blocks 13 to move in the direction of approaching, so that the two movable plates 6 can be driven to abut against the outer wall of the device body 2 more closely, and the two screw rods 18 inside the two movable plates 6 are controlled to rotate, so as to drive the two second movable blocks 16 to move in the direction close to the device body 2, so that the two rotating plates 7 in the vertical state can move together in the direction close to the device body 2 until the two rotating plates 7 are close to each other. The soft pads 20 arranged on the side are in close contact with the device body 2, and the arc-shaped grooves 21 opened on the outer walls of the two soft pads 20 can increase the contact area between the soft pads 20 and the surface of the device body 2, so that the two rotating plates 7 can have an auxiliary clamping and fixing effect on the device body 2. As the two sliders 15 move upward in the slide grooves 14, the clamped device body 2 can be driven to move slowly on the top of the mounting plate 3 until the device body 2 moves upward to a specified height, and then the multiple rotating rods 5 are controlled to rotate slightly in one direction together, driving the device body 2 to rotate and move out from the top of the mounting plate 3, and then the rotated and moved device body 2 is assisted to be removed manually or with related equipment, so that the disassembly of the device body 2 can be completed, which is convenient, fast, easy to operate, and improves the disassembly efficiency of the device body 2.
