It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0025] Embodiment 1:

[0026] Combination Figure 1-3 As shown, this embodiment provides a complete set of pole-mounted transformer station equipment, including: a main body module 100 and a fire extinguishing module 200.

[0027] Among them, the main module 100 includes symmetrically arranged columns 110, a base plate 120 with both ends fixed on the relative columns 110, a transformer box 130 installed on the top of the base plate 120, a distribution box 140 fixed at the bottom of the base plate 120, an air inlet piece 150 symmetrically fixed on the top of the base plate 120, and a rain shield 160 installed on the top of the air inlet piece 150.

[0028] The column 110 is used to install the base plate 120, and the end of the base plate 120 is fixed on the column 110 to ensure the stability of the base plate 120. The transformer box 130 is fixed on the top of the base plate 120, and is used to install the transformer and provide protection for the transformer. The distribution box 140 is used to install electrical equipment for power distribution. First exhaust holes 131 are opened on both sides of the transformer box 130 for discharging hot air inside the transformer box 130. Second exhaust holes 141 are opened on both sides of the distribution box 140 for discharging hot air inside the distribution box 140. In addition, dustproof nets are provided on the inner walls of the first exhaust holes 131 and the second exhaust holes 141 to prevent dust from entering the inner cavities of the transformer box 130 and the distribution box 140.

[0029] A cavity 121 is opened inside the bottom plate 120, and through holes 122 are opened on the inner top wall and the inner bottom wall of the cavity 121 to communicate with the transformer box 130 and the distribution box 140 respectively, so as to facilitate the high-speed airflow in the cavity 121 to enter the transformer box 130 and the distribution box 140 through the through holes 122.

[0030] The air inlet member 150 is connected to the cavity 121, and is used to accelerate the outside air into the cavity 121, including a rectangular tube body 151 fixed on the top of the base plate 120 and connected to the cavity 121, a plurality of high-speed fans 152 installed on the inner wall of the rectangular tube body 151, and a filter 153 installed on the inner wall of the rectangular tube body 151. The rectangular empty tube is used to install the high-speed fan 152, and the high-speed fan 152 faces the direction of the cavity 121 to accelerate the outside air into the cavity 121. The filter 153 is used to filter dust in the air. The rain shield 160 is V-shaped, which is used to prevent rainwater from entering the rectangular empty tube in rainy weather.

[0031] The fire extinguishing module 200 is used to extinguish a fire when an electrical device catches fire, and includes a plurality of smoke sensors 210 respectively installed on the inner walls of the transformer box 130 and the distribution box 140, a plurality of gas tanks 220 symmetrically fixed on both sides of the distribution box 140, a connecting pipe 230 connecting the gas tank 220 and the cavity 121, an electric valve 240 installed on the connecting pipe 230, and an alarm component 250 installed on one side of the base plate 120.

[0032] The smoke sensor 210 is used to monitor in real time whether the electrical equipment in the transformer box 130 and the distribution box 140 generates flames. The gas cylinder 220 is filled with high-pressure inert gas, and the gas cylinder 220 is connected to the cavity 121 through the connecting pipe 230, so that the high-pressure inert gas can enter the cavity 121 through the connecting pipe 230 and enter the transformer box 130 and the distribution box 140 through the through hole 122, thereby reducing the oxygen concentration inside the two and realizing fire extinguishing operations. The electric valve 240 is used to control the opening and closing of the connecting pipe 230.

[0033] The alarm component 250 is used to alert nearby personnel and remind them to stay away from the equipment to avoid fire of the equipment and cause harm to nearby personnel. It includes a speaker 251 symmetrically fixed on one side of the base plate 120 and a strobe light strip 252 installed on one side of the base plate 120. The speaker 251 is used to issue an alarm voice, and the strobe light strip 252 is used to remind nearby personnel of the location of the equipment.

[0034] The working principle and use process of the utility model are as follows: when in use, the high-speed fan 152 is started to accelerate the outside air into the cavity 121, and the high-speed air enters the transformer box 130 and the distribution box 140 through the through hole 122 in the cavity 121, takes away the heat in the transformer box 130 and the distribution box 140, and then is sent out through the first exhaust hole 131 on the transformer box 130 and the second exhaust hole 141 in the distribution box 140, completing the air circulation, and heating the electrical components in the transformer box 130 and the distribution box 140. Heat dissipation: When the electrical components in the transformer box 130 and the distribution box 140 catch fire, the smoke sensor 210 detects the smoke and opens the electric valve 240. At this time, the high-pressure inert gas in the gas tank 220 enters the cavity 121 through the connecting pipe 230, and enters the transformer box 130 and the distribution box 140 through the through hole 122, reducing the oxygen concentration in the inner cavities of the two to achieve fire extinguishing. At the same time, the speaker 251 and the strobe light strip 252 are turned on to alarm nearby personnel, keep them away from the equipment, and avoid harm to personnel.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
