[0027] It is also noted that ventilation holes are provided at the upper and lower ends of the cabinet panel 1, and the two ventilation panels 4 are both hollow rectangles, and the opposite sides of the two ventilation panels 4 are missing so that the air in the cabinet can flow into the ventilation panels 4, and multiple heat dissipation holes are provided around the outer surface of the ventilation panels 4 so that the internal air can flow out and the outside air can flow into the cabinet.

[0028] See also Figures 1 to 3 The unfolding structure in this embodiment includes two unfolding plates 51 rotatably connected to the inner side of the cabinet panel 1, and rotating blocks 52 are fixed at the upper and lower ends of the two unfolding plates 51. The unfolding structure also includes stop blocks 53 fixed to the left and right ends of the bottom of the inner side of the cabinet panel 1. The opposite side of the two unfolding plates 51 is slidably connected to a slider 54, and the opposite ends of the two sliders 54 are hingedly connected to a push block 55. The opposite ends of the two push blocks 55 are fixed with a tooth plate 56, and the opposite sides of the two tooth plates 56 are meshed with gears 57. The outer surfaces of the two tooth plates 56 are slidably connected to a fixed plate 58.

[0029] Among them, the two unfolding plates 51, the cabinet panel 1 and the cabinet door 2 are combined into a metering box, and the cabinet panel 1 is concave in shape. The left side of the cabinet door 2 and the upper and lower ends of the right side of the cabinet panel 1 are hingedly connected by hinges.

[0030] In addition, the upper and lower walls on the inner side of the cabinet panel 1 are provided with two rotating grooves for the rotating block 52 to rotate therein. The two unfolding plates 51 can be flipped on the inner side of the cabinet panel 1 through two sets of rotating blocks 52. The opposite walls of the two unfolding plates 51 are provided with T-shaped sliding grooves for the slider 54 to slide therein. The slider 54 is T-shaped so that the slider 54 can pull the unfolding plate 51 to flip it.

[0031] In addition, the fixed plate 58 is fixed to the top wall on the inner side of the cabinet panel 1, and the left and right walls of the fixed plate 58 are provided with through holes for the tooth plate 56 to move in or out, and the two tooth plates 56 are fixed with anti-slip blocks on the opposite walls. The upper and lower walls of the inner cavity of the fixed plate 58 are provided with anti-slip grooves, and the anti-slip blocks are slidably connected to the inside of the anti-slip grooves, and the upper end of the anti-slip block is T-shaped, so that it can support the tooth plate 56 and prevent the tooth plate 56 from being completely moved out of the fixed plate 58.

[0032] Furthermore, a driving motor is fixed to the rear wall of the inner cavity of the fixing plate 58 , and the gear 57 is fixed to the output end of the driving motor so as to enable the gear 57 to rotate within the fixing plate 58 .

[0033] See also Figure 1 、 Figure 5 and Figure 6 The covering structure in this embodiment includes a vertical plate 43 fixed to the rear wall of the cabinet panel 1, and a slide plate 42 is slidably connected inside the vertical plate 43. A connecting block 44 is fixed to the opposite ends of the two slide plates 42, and a covering plate 41 is fixed to the front walls of the two connecting blocks 44. A dual-axis motor 46 is fixed to the rear wall of the inner cavity of the vertical plate 43, and a screw 45 is fixed to the output end of the dual-axis motor 46.

[0034] Secondly, square holes are provided at the upper and lower ends of the vertical plate 43 for the two slides 42 to move in or out of the interior, so that the two slides 42 can be telescopically moved on the rear wall of the cabinet panel 1, and the opposite ends of the two slides 42 are provided with thread grooves for the screw 45 to extend into the interior, and the threads on the outer surfaces of the two screws 45 turn in opposite directions, so that the two screws 45 can drive the two slides 42 to move relative to or away from each other through the thread groove, and the direction hole can prevent the screw 45 from driving the slide 42 to rotate.

[0035] In addition, opposite sides of the two covering plates 41 are each provided with a receiving slot for allowing the ventilation plate 4 to move in or out of the interior thereof, so that the covering plates 41 can cover the multiple heat dissipation holes of the ventilation plate 4 .

[0036] See also Figure 1 and Figure 4 The fire extinguishing structure in this embodiment includes a spray pipe 21 fixed to the front wall of the cabinet door 2, the front end of the spray pipe 21 is fixed and connected to a plurality of electronic spray heads 22, the fire extinguishing structure also includes a cable-type linear temperature-sensitive fire detector 23 fixed to the front wall of the cabinet door 2, a delivery pipe 24 is fixed to the top of the rear end of the spray pipe 21, and the fire extinguishing structure also includes a storage box 25 fixed to the rear wall of the cabinet door 2.

[0037] At the same time, the right end of the storage box 25 is fixed and connected to a delivery pump, and the output end of the delivery pump is fixed to the other end of the delivery pipe 24 away from the spray pipe 21, so that the perfluorohexanone fire extinguishing agent stored in the storage box 25 can be delivered to the spray pipe 21.

[0038] In addition, a through hole is formed on the front wall of the cabinet door 2 for the delivery pipe 24 to pass through, which is beneficial for the connection between the delivery pipe 24 and the spray pipe 21 .

[0039] In addition, the storage box 25 is filled with perfluorohexanone fire extinguishing agent, which is a new type of environmentally friendly, colorless, non-toxic fire extinguishing agent. The boiling point of this fire extinguishing agent under standard atmospheric pressure is 49.2°C, the freezing point is -108°C, and the dielectric strength is ≥110kV. Its insulation is extremely high. The fire extinguishing agent is liquid at room temperature, which greatly improves the storage, transportation and use performance of the fire extinguishing agent. There is no need to worry about the agent causing harm to the human body.

[0040] Moreover, the cable-type linear temperature-sensing fire detector 23 is composed of a temperature-sensing cable, a detection device and a terminal box. The temperature-sensing cable is laid along the temperature-measured cable, and can intuitively detect temperature changes and abnormalities at any part. Combined with the communication system composed of the detection host and the terminal box, the data can be reported in real time and an alarm can be given at the first time when a fire occurs.

[0041] It should be noted that the cable-type linear temperature-sensing fire detector 23, the electronic sprinkler head 22 and the electronic components appearing in the text are all commonly known to the public in the prior art, and the control method is controlled by the control end, which is commonly known to the public in the prior art, and the existing power connection technology and power supply are also common knowledge in this field. Those skilled in the art can simply program and implement them, so the working principle, circuit connection and control method will not be elaborated in this article.

[0042] The working principle of the above embodiment is:

[0043] When in use, when the electronic components in the metering box are undergoing fault diagnosis, the output end of the driving motor drives the gear 57 to rotate, so that the gear 57 is meshed with the two tooth plates 56, thereby driving the two tooth plates 56 to move backwards, so that the two tooth plates 56 drive the sliders 54 to move through the two push blocks 55, so that the two sliders 54 can move backwards on the two expansion plates 51 through the T-shaped slide grooves, and the two sliders 54 continue to move backwards while pushing the two expansion plates 51 to flip and unfold, thereby expanding the operating space in the metering box, so as to increase the space for staff to perform fault diagnosis operations, which is conducive to improving the convenience of fault diagnosis; and when the two sliders 54 move backwards, the two expansion plates 51 can be pulled to flip in the opposite direction and flipped to the inside of the cabinet board 1, and the two stoppers 53 can block the expansion plates 51 in the flipping cabinet board 1, so that the two expansion plates 51 can fit tightly with the cabinet board 1;

[0044] When the cable-type linear heat-sensing fire detector 23 senses a temperature change or abnormality of an electronic component somewhere in the metering box, it sends a signal to the control end, causing the delivery pipe 24 to extract the perfluorohexanone fire extinguishing agent from the storage box 25 through the delivery pump and deliver it to the spray pipe 21. The electronic spray head 22 at the corresponding position sprays the perfluorohexanone fire extinguishing agent to the abnormal area, thereby enabling the metering box to have a fire extinguishing function;

[0045] Moreover, while extinguishing the fire, the output end of the dual-axis motor 46 drives the two screws 45 to rotate, so that the two screws 45 are threadedly connected to the slide plate 42 through the thread groove thereof, thereby driving the two slide plates 42 to move relative to each other, and the two slide plates 42 drive the two cover plates 41 to move relative to each other through the connecting block 44, so that the ventilation plate 4 moves into the storage groove of the cover plate 41, thereby blocking the multiple heat dissipation holes of the ventilation plate 4, making the metering box in an oxygen-free state, which can further accelerate the fire extinguishing efficiency.

[0046] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
