DETAILED DESCRIPTION
[0028] To facilitate understanding of this utility model, a more comprehensive description of this application will be given below with reference to the accompanying drawings, which show preferred embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this utility model.
[0029] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0031] like Figures 1 to 5 As shown, this application provides a transformer oil draining and nitrogen injection fire extinguishing device, including a fire cabinet 100 and an oil draining tank 130. An oil draining pipe 110 is fixed inside the fire cabinet 100. One end of the oil draining pipe 110 is connected to the top of the transformer, and the other end of the oil draining pipe 110 extends into the oil draining tank 130. A nitrogen injection pipe 120 is fixed on the fire cabinet 100. A nitrogen cylinder is installed inside the fire cabinet 100. One end of the nitrogen injection pipe 120 is connected to the bottom of the transformer, and the other end of the nitrogen injection pipe 120 is connected to the nitrogen cylinder. It also includes a ventilation component 200.
[0032] The ventilation assembly 200 includes a telescopic part 210 and a ventilation net 230;
[0033] The telescopic part 210 is movably connected to the side of the fire cabinet 100. The telescopic part 210 is a hydraulic cylinder, and its telescopic end is fixed with a sealing plate 220. In the initial state, when the sealing plate 220 is not opened, the internal space of the fire cabinet 100 is relatively sealed, which can prevent insects and rodents from entering the fire cabinet 100.
[0034] The fire cabinet 100 has a through groove on its side, the ventilation net 230 is fixed in the through groove, the sealing plate 220 is parallel to the ventilation net 230, and the sealing plate 220 is located outside the ventilation net 230.
[0035] It is worth noting that when ventilating the fire cabinet 100, the telescopic part 210 drives the sealing plate 220 to flip outward, moving it away from the ventilation net 230 and exposing the ventilation net 230 to the outside, which facilitates ventilation inside the fire cabinet 100. At the same time, the telescopic part 210 repeatedly extends and retracts, causing the sealing plate 220 to flip repeatedly, thereby increasing the efficiency of ventilation inside the fire cabinet 100.
[0036] Specifically, such as Figures 4 to 8 As shown, the ventilation assembly 200 also includes a movable part 240;
[0037] The moving part 240 includes a reciprocating lead screw 241 and a guide rod 243;
[0038] The reciprocating screw 241 is movably connected inside the fire cabinet 100. A motor is fixed on the top of the fire cabinet 100. The motor is used to drive the reciprocating screw 241 to rotate. A moving block 242 is threadedly connected to the reciprocating screw 241. A fixing plate 244 is fixed on one side of the moving block 242.
[0039] The guide rod 243 is fixed inside the fire cabinet 100, and one side of the fixing plate 244 is fitted onto the guide rod 243. In other words, the guide rod 243 is used to guide the fixing plate 244 to prevent the fixing plate 244 from flipping over.
[0040] Specifically, such as Figure 8 As shown, a support plate 245 is fixed on the fixed plate 244, and multiple ventilation fans 2451 are fixed on the support plate 245. The ventilation fans 2451 are parallel to the ventilation net 230.
[0041] In the above embodiment, when ventilating the fire cabinet 100, the sealing plate 220 is opened by the telescopic part 210, and then the ventilation fan 2451 is started. The ventilation fan 2451 accelerates the airflow inside the fire cabinet 100, and expels the humid gas inside the fire cabinet 100 more quickly. The motor drives the reciprocating screw 241 to rotate, which drives the moving block 242 to move at the reciprocating screw 241, so that the fixed plate 244 moves up and down, and the ventilation fan 2451 disperses the moisture inside the fire cabinet 100 in all directions.
[0042] In some embodiments of this application, such as Figures 4 to 8 As shown, a brush plate 2442 is fixed on the fixing plate 244 near the ventilation mesh 230, and the brush plate 2442 is in contact with the mesh of the ventilation mesh 230.
[0043] As is easily understood, the brush plate 2442 can clean the dust from the mesh of the ventilation screen 230, preventing the mesh of the ventilation screen 230 from becoming clogged and affecting ventilation.
[0044] Specifically, such as Figures 6 to 8 As shown, the fixing plate 244 is a rectangular plate with a hollow interior and an opening on one side, and a gas soft bag 2441 is fixed inside it, and the brush plate 2442 is fixed on the gas soft bag 2441.
[0045] A ventilation tube 2444 is fixed on the fixed plate 244. One side of the ventilation tube 2444 is connected to an air pump, which is fixed on the fixed plate 244. The other end of the ventilation tube 2444 extends into the gas soft bag 2441.
[0046] As is easily understood, by inflating the air pipe 2444 with an air pump, the gas soft bag 2441 expands and drives the brush plate 2442 to extend into the mesh of the ventilation net 230, so as to better clean the dust in the mesh of the ventilation net 230 and ensure the ventilation effect of the ventilation net 230.
[0047] Specifically, such as Figures 6 to 8 As shown, a collection groove 2443 is fixed to the bottom of the fixing plate 244. The collection groove 2443 is located below the brush plate 2442 and is used to collect the dust cleaned down by the ventilation mesh 230.
[0048] Based on the above embodiments, when the fixed plate 244 lifts and lowers to drive the ventilation fan 2451 to ventilate, the gas soft bag 2441 is filled and evacuated through the ventilation pipe 2444, causing the gas soft bag 2441 to repeatedly expand and contract and drive the brush plate 2442 to repeatedly hammer the ventilation mesh 230, knocking off the dust at the mesh openings of the ventilation mesh 230, and using the brush plate 2442 to clean the mesh openings of the ventilation mesh 230. The dust that falls from the ventilation mesh 230 enters the collection tank 2443, which facilitates the centralized treatment of dust, improves the ventilation efficiency inside the fire cabinet 100, and better removes the humid gas inside the fire cabinet 100.
[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
