Specific embodiments

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0027] As Figure 1 , Figure 2 and Figure 3 shown, a control cabinet for integrated management of lithium batteries includes: a cabinet 20, the cabinet 20 is in the shape of a hollow rectangular box with a front wall that can be flipped open, the top of the cabinet 20 is open, a battery rack 21 is fixedly connected inside the cavity of the cabinet 20, the battery rack 21 is in the shape of a hollow rectangular box with an open front wall, a plurality of battery racks 21 are vertically stacked inside the cavity of the cabinet 20, and lithium batteries can be installed inside the cavity of the battery rack 21. This is the prior art, so it will not be elaborated here.

[0028] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a fire prevention structure, the fire prevention structure is used to isolate the lithium batteries in the cavity of the battery rack 21 when they catch fire inside the cavity of the cabinet 20. The fire prevention structure includes a top rack 30, a cloth-receiving roller 31 and a sliding frame 32. The top rack 30 is fixedly connected to the inner wall surface of the cavity of the cabinet 20, the cloth-receiving roller 31 is fixedly connected to the wall surface of the top rack 30, the sliding frame 32 is slidably connected inside the cavity of the cabinet 20, and the sliding frame 32 can slide vertically inside the cavity of the cabinet 20.

[0029] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the top frame 30 is symmetrically arranged at the top of each wall surface around the inner cavity of the cabinet body 20. The cloth winding roller 31 is rotatably connected between each pair of symmetric top frames 30. The cloth winding roller 31 is cylindrical, and the sliding frame 32 is in the shape of a rectangular frame. The outer wall surface of the sliding frame 32 can contact the wall surfaces around the inner cavity of the cabinet body 20. The fireproof structure further includes sliders 33 and chutes 34. The sliders 33 are symmetrically and fixedly connected to the two side wall surfaces of the sliding frame 32 respectively. The chutes 34 are opened on the inner wall surface of the cabinet body 20 at the positions of each slider 33. The sliders 33 can slide vertically in the chutes 34, and the chutes 34 can adapt to the shape of the sliders 33. The fireproof structure further includes a wire binding groove 35, a binding post 36, a straight rod 37 and a wire binding rod 38. The wire binding groove 35 is opened on the inner wall surface of the sliding frame 32. The binding post 36 is fixedly connected in the wire binding groove 35. The straight rod 37 is fixedly connected to the top wall surface of the battery rack 21 at the uppermost part in the cabinet body 20. The wire binding rod 38 is fixedly connected to the wall surface of the straight rod 37 corresponding to the direction of the binding post 36. The binding post 36 is cylindrical. The wire binding groove 35 and the binding post 36 are symmetrically arranged on the inner wall of the sliding frame 32. The wire binding rods 38 are also symmetrically arranged on the two wall surfaces of the straight rod 37. The top of the wire binding rod 38 is in an L shape, and the position of the wire binding rod 38 is horizontally aligned with the binding post 36;

[0030] During specific use, before use, one end of the fireproof cloth needs to be manually fixed to the outer wall of each cloth winding roller 31 and wound. After the fireproof cloth is wound, the other end of the fireproof cloth is fixedly connected to the top of the sliding frame 32. At this time, one end of the wire is fixed and tied in the binding post 36 in the wire binding groove 35, and the other end is tied and fixed to the wall surface of the wire binding rod 38 and the wire is straightened. When a fire occurs in the cabinet body 20 cavity, the flame will burn the wire tied between the straight rod 37 and the binding post 36. When the wire is burned off, the sliding frame 32 will move vertically downward because there is no attachment. When the sliding frame 32 moves, it will drive the slider 33 to slide in the chute 34. The sliding frame 32 will also drive the fireproof cloth to extend downward during movement. The fireproof cloth will drive the cloth winding roller 31 to rotate. When the sliding frame 32 moves to the lowest position in the cabinet body 20 cavity, it will stop moving. At this time, the fireproof cloth will surround the burning battery rack 21 and the lithium battery to prevent the flame from spreading;

[0031] In summary, by setting the fireproof structure, the operation will not fail due to the presence of obstacles around the cabinet body 20. Because the fireproof structure drives the fireproof cloth to cover the lithium battery on all sides when the lithium battery in the cabinet body 20 catches fire through the sliding frame 32 that can move in the cabinet body 20 cavity, and there will be no problem that the position of the sliding frame 32 is blocked by obstacles during this operation process. Therefore, compared with the prior art, the conditions for the operation of this solution are simpler and can achieve the same fireproof effect.

[0032] Such as Figure 1 and Figure 5As shown, horizontal edges 40 are symmetrically and fixedly connected to the top of the cabinet body 20. A horizontal groove 41 is formed in the wall surface of the horizontal edge 40. A horizontal block 42 is slidably connected in the horizontal groove 41. A baffle 43 is fixedly connected to the wall surface of the horizontal block 42. The horizontal groove 41 is formed in the wall surfaces of the symmetric horizontal edges 40 facing each other. The horizontal block 42 is provided in each horizontal groove 41. The baffle 43 is fixedly connected between the symmetric horizontal blocks 42. The bottom of the baffle 43 can cover the top of the cabinet body 20.

[0033] During specific use, when it is necessary to extinguish the fire in the cavity of the cabinet body 20, first, the baffle 43 is pushed horizontally. When the baffle 43 is translated, the horizontal block 42 will slide in the horizontal groove 41. After the baffle 43 slides, the top of the cabinet body 20 will be in an open state at this time. At this time, the fire extinguisher can be sprayed towards the top of the cabinet body 20.

[0034] In summary, by setting the baffle 43 that can be opened, it can quickly open the top of the cabinet body 20 and spray the fire extinguisher inward when it is necessary to extinguish the fire in the cavity of the cabinet body 20, thereby achieving a better fire extinguishing effect on the cavity of the cabinet body 20 quickly.

[0035] Working principle: Before use, one end of the fireproof cloth needs to be manually fixed on the outer wall of each cloth-receiving roller 31 and wound up. After the fireproof cloth is wound up, the other end of the fireproof cloth is fixedly connected to the top of the sliding frame 32. At this time, one end of the wire is fixed and tied in the tying post 36 in the wire-tying groove 35, and the other end is tied and fixed to the wall surface of the wire-tying rod 38 and the wire is tightened. When a fire occurs in the cavity of the cabinet body 20, the flame will burn the wire tied between the straight rod 37 and the tying post 36. When the wire is burned off, the sliding frame 32 will move vertically downward because there is no attachment. When the sliding frame 32 moves, it will drive the slider 33 to slide in the sliding groove 34. The sliding frame 32 will also drive the fireproof cloth to extend downward when moving. The fireproof cloth will drive the cloth-receiving roller 31 to rotate. When the sliding frame 32 moves to the lowest position in the cavity of the cabinet body 20, it will stop moving. At this time, the fireproof cloth will surround the burning battery rack 21 and the lithium battery to prevent the spread of the flame.
