DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0023] There are two doors 5 , which are symmetrically distributed about the central axis of the transformer substation body 1 , so as to reduce the space occupied by the doors 5 when opened.

[0024] See also Figure 2-3 In order to improve the utilization rate of rainwater, the water collection mechanism 3 in this embodiment includes a box eaves 301 fixed on the outside of the box top 2, and the lower surface of the box eaves 301 is connected with a connecting pipe 302. When rainwater flows to the box eaves 301, the box eaves 301 guides the rainwater to flow into the connecting pipe 302. A water tank 303 is fixed on the left side of the substation body 1. The bottom end of the connecting pipe 302 penetrates and extends to the inside of the water tank 303. Rainwater flows from the connecting pipe 302 into the water tank 303 and is stored for subsequent use. A filtering component is provided inside the connecting pipe 302.

[0025] In this example, the left side of the water tank 303 is connected to a drain pipe 304 , and the outside of the drain pipe 304 is connected to a drain valve 305 . If the rainwater deteriorates, the drain valve 305 is opened to drain the rainwater inside the water tank 303 from the drain pipe 304 .

[0026] It should be noted that the filter assembly includes a placement groove 306 provided on the inner bottom wall of the box eaves 301, and a support rod 307 is placed on the inner bottom wall of the placement groove 306. The placement groove 306 can limit the position of the support rod 307 to prevent the support rod 307 from falling into the connecting pipe 302. A connecting rod 308 is fixed to the outside of the support rod 307. The other end of the connecting rod 308 penetrates and extends to the inside of the connecting pipe 302, and a filter screen 309 is fixed to the outside. When rainwater flows in the connecting pipe 302, it will first pass through the filter screen 309, and the filter screen 309 will be used to filter the rainwater. 9 Some larger dust and impurities in the rainwater are filtered out. An activated carbon plate 310 is fixed to the bottom end of the connecting rod 308. The filtered rainwater passes through the activated carbon plate 310, and the activated carbon plate 310 adsorbs smaller impurity particles in the rainwater, thereby preventing the rainwater from deteriorating during storage in the water tank 303. The number of connecting pipes 302 is two, and they are symmetrically distributed around the central axis of the substation body 1. The number of placement slots 306 is equal to the number of connecting pipes 302, and the positions correspond one to one, so as to collect rainwater from both sides.

[0027] See also Figure 4 In order to improve the efficiency of heat dissipation in the substation, the heat dissipation mechanism 4 in this embodiment includes an air inlet 401 opened on the back of the substation body 1, and a fan 402 is fixed on the inner side of the air inlet 401. The cold air from the outside is drawn into the inside of the substation body 1 from the air inlet 401 through the fan 402, and heat is exchanged with the hot air inside the substation body 1. The left and right sides of the substation body 1 are provided with air outlets 403, and the hot air is discharged from the substation body 1 from the air outlets 403. A grille 404 is fixed on the inner side of the air outlet 403, and the grille 404 can reduce the entry of dust. A booster pump 405 is fixed on the upper surface of the water tank 303, and the input end of the booster pump 405 is connected to a water inlet pipe 406. The water inlet pipe 40 6 penetrates and extends to the interior of the water tank 303, the booster pump 405 pumps out the rainwater in the water tank 303 through the water inlet pipe 406, the output end of the booster pump 405 is connected with an outlet pipe 407, the other end of the outlet pipe 407 penetrates and extends to the interior of the substation body 1, and is connected with a cooling pipe 408, the rainwater is passed into the cooling pipe 408 through the outlet pipe 407, the other end of the cooling pipe 408 penetrates and extends to the interior of the water tank 303, the rainwater flows in the cooling pipe 408, can take away part of the heat of the electrical appliances in the substation body 1, thereby cooperating with the fan 402 to dissipate heat, improve the efficiency of heat dissipation, and finally the rainwater that has absorbed the heat returns to the water tank 303 and can be recycled.

[0028] In this example, the number of the air inlets 401 and the number of the air outlets 403 are both two, and they are both symmetrically distributed about the central axis of the substation body 1 , so as to improve the ventilation speed inside the substation body 1 .

[0029] The working principle of the above embodiment is:

[0030] (1) When it rains, rainwater falls on the top of the substation body 1. Under the action of the box top 2, the rainwater will flow downward to avoid accumulation on the top of the substation body 1. The rainwater flows to the box eaves 301. The box eaves 301 guides the rainwater to flow into the connecting pipe 302. The rainwater flows from the connecting pipe 302 into the water tank 303 and is stored for subsequent use. When the rainwater flows in the connecting pipe 302, it will first pass through the filter 309. The filter 309 filters out some large dust and impurities in the rainwater. The filtered rainwater passes through the activated carbon plate 310. The activated carbon plate 310 adsorbs smaller impurity particles in the rainwater, thereby preventing the rainwater from deteriorating during storage in the water tank 303. If the rainwater deteriorates, open the drain valve 305 to discharge the rainwater in the water tank 303 from the drain pipe 304.

[0031] (2) In daily operation, the heat dissipation of the substation body 1 is performed by air cooling. The fan 402 draws cold air from the outside into the substation body 1 through the air inlet 401, exchanges heat with the hot air inside the substation body 1, and discharges the hot air from the substation body 1 through the air outlet 403. The grille 404 can reduce the entry of dust. After rainy weather, a certain amount of rainwater is stored in the water tank 303. Then, the booster pump 405 can be turned on. The booster pump 405 draws the rainwater from the water tank 303 through the water inlet pipe 406, and then passes the rainwater into the cooling pipe 408 through the water outlet pipe 407. The rainwater flows inside the cooling pipe 408, which can take away part of the heat of the electrical appliances inside the substation body 1, thereby cooperating with the fan 402 to dissipate heat and improve the efficiency of heat dissipation.
