[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9, the present utility model provides a technical solution: a bidirectional inverter energy storage power supply, including a power supply main body 1. An air inlet 11 is provided on the back surface of the power supply main body 1, and an air outlet 12 is provided on the back surface of the power supply main body 1 and below the air inlet 11. A filter screen 13 is fixedly connected to the inner wall of the air inlet 11, and a heat dissipation fan 14 is fixedly connected to one side of the filter screen 13. A sealing component is provided on the back surface of the power supply main body 1, and a supporting component is provided on the outside of the power supply main body 1. The sealing component includes a first baffle 21 provided on one side of the air inlet 11, a second baffle 22 provided on one side of the air outlet 12, a first rotating shaft 23 fixedly connected to the first baffle 21, a second rotating shaft 24 fixedly connected to the second baffle 22, support plates 25 respectively connected to both sides of the first rotating shaft 23 and the second rotating shaft 24, and a linkage component for synchronously rotating the first baffle 21 and the second baffle 22. Both the first rotating shaft 23 and the second rotating shaft 24 are rotatably connected to the support plates 25, and the support plates 25 are fixedly connected to the power supply main body 1. When the heat dissipation fan 14 works, it can dissipate heat from the power supply main body 1. When the heat dissipation fan 14 does not work, the rotation of the first rotating shaft 23 and the second rotating shaft 24 can drive the rotation of the first baffle 21 and the second baffle 22. The first baffle 21 and the second baffle 22 can close the air inlet 11 and the air outlet 12, preventing external humid air or rainwater from entering the power supply main body 1, and protecting the power supply main body 1. The linkage component includes a driving wheel 41 fixedly connected to the outside of the first rotating shaft 23, a driven wheel 42 fixedly connected to the outside of the second rotating shaft 24, a belt 43 provided between the driving wheel 41 and the driven wheel 42, and a motor 44 fixedly connected to one end of the first rotating shaft 23. The driving wheel 41 and the driven wheel 42 are connected by belt drive. The motor 44 can control the rotation of the first rotating shaft 23, and then drive the rotation of the driving wheel 41. Using the belt 43, it can drive the rotation of the driven wheel 42 and the second rotating shaft 24, and then make the first baffle 21 and the second baffle 22 rotate synchronously, reducing the use cost. Installation grooves 61 are respectively provided on the back surface of the power supply main body 1 and below the air inlet 11 and the air outlet 12. Magnets 62 are fixedly connected in the installation grooves 61. Adsorbing irons 63 are fixedly connected to one side of the first baffle 21 and the second baffle 22. When the first baffle 21 and the second baffle 22 rotate to the vertical state, the adsorbing iron 63 can adsorb and fix with the magnet 62, improving the fixing stability of the first baffle 21 and the second baffle 22 and preventing their rotation.

[0029] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, the support member includes a horizontal plate 31 fixedly connected to the periphery of the power supply main body 1 respectively, a moving port 32 opened at the top of the horizontal plate 31, a moving rod 33 arranged in the moving port 32, a support seat 34 fixedly connected to the bottom of the moving rod 33, a limiting plate 35 fixedly connected to the top of the moving rod 33, a sliding port 36 opened on one side in the moving port 32, a locking rod 37 arranged in the sliding port 36, a pulling plate 38 fixedly connected to one end of the locking rod 37, a spring 39 sleeved outside the locking rod 37, and a plurality of locking grooves 40 arranged in a uniform array on one side of the moving rod 33. The locking rod 37 is slidably connected to the sliding port 36, the locking rod 37 is inserted into the locking grooves 40, and the moving rod 33 is slidably connected to the moving port 32. By pulling the pulling plate 38, the locking rod 37 can be moved. The two ends of the spring 39 are fixedly connected to the horizontal plate 31 and the pulling plate 38 respectively. Therefore, the spring 39 deforms under force, and the locking rod 37 moves out of the locking grooves 40, so that the moving rod 33 can drive the support seat 34 to move vertically. When the spring 39 resets, it can drive the locking rod 37 to insert into the locking grooves 40, and the support seat 34 can be fixed. According to the ground conditions, the heights of the four support seats 34 can be adjusted, so that the power supply main body 1 can be kept in a horizontal state, which is convenient for using the power supply main body 1. An anti-slip pad 81 is arranged at the bottom of the support seat 34, and the anti-slip pad 81 is fixedly connected to the support seat 34. The anti-slip pad 81 can increase the friction between the support seat 34 and the ground, improve the use stability of the power supply main body 1, and prevent it from shifting. A rotation stopping groove 51 is opened on the side of the moving port 32 opposite to the sliding port 36. A rotation stopping plate 52 is slidably connected in the rotation stopping groove 51, and the rotation stopping plate 52 is fixedly connected to the moving rod 33. The rotation stopping plate 52 can move vertically synchronously with the moving rod 33, thereby preventing the moving rod 33 from rotating, and then facilitating the alignment of the locking rod 37 with the locking grooves 40 and fixing the moving rod 33. A fixing rod 71 is fixedly connected to one side of the pulling plate 38, and a pulling ring 72 is fixedly connected to one end of the fixing rod 71. Through the pulling ring 72, the pulling plate 38 can be conveniently driven to move horizontally, and then the locking rod 37 can be conveniently driven to move, the support seat 34 can be conveniently released, and then the vertical height of the support seat 34 can be conveniently adjusted.

[0030] Working principle: During operation, pull the pull ring 72. The pull ring 72 can drive the pull plate 38 and the lock rod 37 to move. At the same time, the spring 39 deforms under force, and the lock rod 37 moves out of the lock groove 40. At this time, the moving rod 33 can be pushed to move vertically, and then the support base 34 can be driven to move vertically. After adjusting the support base 34 to the appropriate position, release the pull ring 72. The reset of the spring 39 can drive the lock rod 37 to snap into the lock groove 40, and the support base 34 can be fixed. According to the ground conditions, the vertical heights of the four support bases 34 can be adjusted in sequence, so that the power supply main body 1 can be kept horizontal, which is convenient for its use. When the cooling fan 14 is not working, the motor 44 can be started. The motor 44 can drive the first rotating shaft 23 to rotate. The rotation of the first rotating shaft 23 can drive the first baffle 21 and the driving wheel 41 to rotate. The driving wheel 41 can drive the belt 43 to rotate. The belt 43 can drive the driven wheel 42 to rotate. The rotation of the driven wheel 42 can drive the second rotating shaft 24 to rotate. The second rotating shaft 24 can drive the second baffle 22 to rotate. The adsorption iron 63 and the magnet 62 adsorb and fix each other to prevent the first baffle 21 and the second baffle 22 from rotating. The rotation of the first baffle 21 and the second baffle 22 can close the air inlet 11 and the air outlet 12, and prevent humid air or rainwater from entering the power supply main body 1. When heat dissipation is required, the motor 44 can be started to reverse, so that the first rotating shaft 23 and the second rotating shaft 24 can rotate in the reverse direction, and then the first baffle 21 and the second baffle 22 can be driven to rotate, and the air inlet 11 and the air outlet 12 can be exposed to facilitate heat dissipation. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
