[0023] like Figures 1 to 3 As shown:

[0024] A power distribution cabinet capable of automatic cooling comprises a cabinet body 101, the upper end of the cabinet body 101 is sealed with a cover plate 102, at least one ventilation slot 103 is arranged on the side end surface of the cabinet body 101, a baffle member capable of blocking the ventilation slot 103 is hingedly connected to the ventilation slot 103, a driving member is installed at the outer end of the cabinet body 101, two trapezoidal slots are arranged on the cabinet body 101, two trapezoidal blocks matching the trapezoidal slots are arranged on the outer box body 405, the outer box body 405 is slidably connected in the trapezoidal slots through the trapezoidal blocks, the driving member can support the outer box body 405, the outer box body 405 slides down under the action of gravity after receiving rainwater, and then the baffle member can be driven by the driving member to rotate into the cabinet body 101;

[0025] The bottom surface of the cabinet 101 is provided with a leg with a screw hole for inserting the screw to fix the cabinet 101 on the ground or platform. Under normal circumstances, the outer end of the baffle member is downward in contact with the driving member, the outer end of the baffle member can receive rainwater, and the inner end of the baffle member is upward and fits with the inner wall of the cabinet 101, thereby blocking the ventilation slot 103 from the inside to prevent external dust, debris, rainwater and insects from entering the cabinet 101 through the ventilation slot 103, thereby ensuring that the interior of the distribution cabinet is dust-free. When it rains, the outer box body 405 receives full rainwater and fits with the rear end surface of the cabinet 101, thereby the rainwater stored in the outer box body 405 can cool down the outer wall of the cabinet 101, thereby promoting the cooling of the interior of the cabinet 101; secondly, the outer box body 405 is full of rainwater. After the water is absorbed by the cabinet 101, the outer box body 405 slides downward under the action of gravity, and the outer box body 405 automatically drives the driving part to work, and the driving part automatically drives the baffle part to rotate upward until the outer end of the baffle part is buckled on the outer wall of the cabinet 101. At this time, the baffle part blocks the ventilation slot 103 from the outside, and when the baffle part rotates, the rainwater stored at the outer end of the baffle part slides to the inner end of the baffle part, and the rainwater located on the inner side of the cabinet 101 can evaporate when the temperature inside the cabinet 101 is high, thereby promoting cooling inside the cabinet 101, thereby achieving cooling of the surface of the cabinet 101 by absorbing the rainwater, and delivering the rainwater to the inside of the cabinet 101, promoting cooling of the cabinet 101 from the inside, and achieving automatic cooling of the distribution cabinet from both the inside and the outside.

[0026] like Figures 3 to 6 As shown:

[0027] The baffle member includes an articulated seat 201 hinged on the ventilation slot 103, and an inner gusset plate 204 and an outer gusset plate 202 are integrally formed at the inner and outer ends of the articulated seat 201, respectively. A groove is provided on the top surface where the articulated seat 201, the outer gusset plate 202 and the inner gusset plate 204 are located, and the position of the groove corresponding to the outer gusset plate 202 is concave downward to store rainwater, and a long groove communicating with the groove is provided on the inner gusset plate 204;

[0028] A counterweight strip 203 is bonded to the bottom surface of the outer gusset plate 202, so that the outer gusset plate 202 is tilted downward in normal state, and the inner gusset plate 204 is upwardly fitted with the inner wall of the cabinet 101, and the hinge seat 201 and the inner gusset plate 204 simultaneously block the ventilation slot 103 from the inside to prevent dust, insects and debris from entering the cabinet 101; when the driving member drives the outer gusset plate 202 to rotate upward, the outer gusset plate 202 is fitted on the outer wall of the cabinet 101, and at this time, the outer gusset plate 202 and the hinge seat 201 simultaneously block the ventilation slot 103 from the outside to prevent dust, insects and debris from entering the cabinet 101, and at the same time, the inner gusset plate 204 is separated from the inner wall of the cabinet 101 and turns to the inside of the cabinet 101. At this time, the rainwater stored in the groove where the outer gusset plate 202 is located flows toward the long groove on the inner gusset plate 204, and the rainwater exists in the long groove inside the cabinet 101, so that the temperature inside the cabinet 101 increases and the interior can be cooled by evaporating the rainwater in the long groove. At the same time, the dust floating in the cabinet 101 due to the high temperature in the cabinet 101 can fall into the rainwater in the long groove, which has a role in adsorbing the dust in the cabinet 101.

[0029] like Figure 6 As shown:

[0030] A sponge strip 205 is inserted into the long groove and bonded into the long groove. The sponge strip 205 can absorb rainwater. When the inner gusset plate 204 rotates inward, the rainwater flowing into the long groove is absorbed by the inner gusset plate 204, so as to prevent the rainwater in the long groove from being ejected or sliding out of the long groove and splashing onto the electrical components when the inner gusset plate 204 rotates inward, thereby damaging the electrical components. The rainwater absorbed on the sponge strip 205 can also evaporate and thus cool down the interior of the cabinet 101.

[0031] Further:

[0032] The inner gusset plate 204 is evenly distributed with a plurality of slots 207 connected to the long slots. The plurality of slots 207 make the bottom surface of the sponge strip 205 corresponding to the slots 207 also hollow, thereby increasing the contact area between the sponge strip 205 that absorbs rainwater and the high-temperature gas in the cabinet 101, thereby increasing the volatilization of rainwater on the sponge strip 205, and thus cooling the interior of the cabinet 101 more quickly.

[0033] like Figure 1 , Figure 3 and Figure 6 As shown:

[0034] A power distribution cabinet capable of automatically cooling down also includes a liquid separator 301. The liquid separator 301 is fixedly connected to the lower end of the ventilation slot 103 on the inner wall of the cabinet body 101 by screws. The inner buckle plate 204 is rotated inward and abuts against the liquid separator 301, so that when there is a lot of water stored in the long slot and the sponge strip 205 cannot completely absorb it, the excess water in the long slot can flow out through a plurality of slot holes 207 and be collected in the liquid separator 301, so that rainwater that can cool down the high temperature is stored in both the sponge strip 205 and the liquid separator 301 in the cabinet body 101, thereby improving the cooling efficiency in the cabinet body 101.

[0035] like Figures 3 to 5 As shown:

[0036] The liquid separator 301 is fixedly connected to an inner box body 302, the inner box body 302 is in contact with the inner wall of the cabinet 101, and the inner box body 302 and the liquid separator 301 are connected via a short tube;

[0037] When the rainwater in the liquid separator 301 can be retained on the inner box body 302 through the short tube, the rainwater in the liquid separator 301 is distributed, so that the rainwater can be distributed in a wider range in the cabinet 101, and the high temperature in a wider range in the cabinet 101 can be cooled, thereby improving the cooling efficiency of the cabinet 101;

[0038] Secondly, the inner box body 302 is attached to the inner wall of the cabinet 101, and the rainwater in the inner box body 302 can cool the inner wall of the cabinet 101 from the inside, and cooperate with the outer box body 405 attached to the outer wall of the cabinet 101 to cool the rear end surface of the cabinet 101 from both inside and outside.

[0039] like Figure 7 As shown:

[0040] A plurality of rotating shafts 303 are inserted into the liquid separation bucket 301, and a stirring wheel 304 is fixedly connected to the rotating shaft 303 in the liquid separation bucket 301;

[0041] When the rotating shaft 303 rotates, it can drive the stirring wheel 304 to rotate. The stirring wheel 304 is located in the rainwater in the liquid separation bucket 301. When the stirring wheel 304 rotates, it can stir the rainwater, thereby promoting the volatilization of the rainwater in the liquid separation bucket 301 and improving the cooling effect.

[0042] Further:

[0043] The inner gusset plate 204 is evenly distributed with a plurality of insertion holes 206, and the diameter of the stirring wheel 304 is smaller than that of the insertion hole 206; when the inner gusset plate 204 is rotated downward to abut against the liquid separator 301, the stirring wheel 304 corresponds to the insertion hole 206, and the rotating shaft 303 slides on the liquid separator 301, so that the stirring wheel 304 can be inserted into the insertion hole 206, thereby squeezing the sponge strip 205, squeezing the rainwater adsorbed on the sponge strip 205, and squeezing the rainwater out of the insertion hole 206 along the inclined inner gusset plate 204 and falling on the liquid separator 301, and then staying on the inner box body 302 from the liquid separator 301, and then squeezing the rainwater on the sponge strip 205 so that it is widely distributed in the cabinet 101, thereby improving the cooling effect;

[0044] When the rainwater on the outer box body 405 evaporates, the weight of the outer box body 405 decreases, and the driving member drives the outer box body 405 to move upward and reset. At the same time, the outer buckle plate 202 rotates downward and resets, and the inner buckle plate 204 is re-fastened to the inner wall of the cabinet 101. At this time, if there is still rainwater adsorbed on the sponge strip 205, the sponge strip 205 adsorbed with rainwater can cool down the inner wall of the cabinet 101 through the evaporation of rainwater.

[0045] Further:

[0046] Two guide rods 306 are welded and connected to the liquid separation bucket 301, and the two guide rods 306 are slidably connected to the shaft frame 305. Multiple rotating shafts 303 are rotatably connected to the shaft frame 305 through bearings. An electric push rod is fixedly connected between the shaft frame 305 and the liquid separation bucket 301. Multiple rotating shafts 303 are keyed to first pulleys. The shaft frame 305 is fixedly connected to a reduction motor. The output shaft of the reduction motor is keyed to a second pulley. The second pulley and the multiple first pulleys are connected by a belt transmission. When the reduction motor is started, the belt transmission connection between the second pulley and the multiple first pulleys drives the multiple rotating shafts 303 to rotate, and then drives the stirring wheel 304 to rotate, so as to stir the rainwater, improve the fluidity of the rainwater, and promote its volatilization at high temperature.

[0047] The electric push rod is started to drive the shaft frame 305 to slide on the two guide rods 306, and then drives the multiple rotating shafts 303 and the stirring wheel 304 to be inserted into the insertion hole 206 to squeeze the sponge strip 205, or to be pulled out from the insertion hole 206.

[0048] like Figure 2 and Figure 8 As shown:

[0049] The driving member includes a long rod 402 vertically slidably connected to the cabinet 101, a spring is fixedly connected between the long rod 402 and the cabinet 101, a lever 401 is fixedly connected to the long rod 402 by a screw, one end of the lever 401 is located at the lower end of the outer gusset plate 202, the other end of the lever 401 is slidably connected to one end of a double-grooved rod 403, the double-grooved rod 403 is rotatably connected to the cabinet 101 through a hinge shaft, the other end of the double-grooved rod 403 is slidably connected to a column 404, and the column 404 is welded to the outer box body 405;

[0050] Due to the effect of the spring, the long rod 402 is given a supporting force, so that the lever 401 and the double-grooved rod 403 can cooperate to support the outer box body 405 through the column 404. When the rainwater in the outer box body 405 increases, the gravity becomes larger and slides downward, the column 404 drives the double-grooved rod 403 to rotate, and the double-grooved rod 403 drives the lever 401 to slide upward, thereby driving the outer buckle plate 202 to rotate upward, and the rainwater is sent to the inside of the cabinet 101. When the rainwater in the outer box body 405 becomes lighter, the outer box body 405 is reset, driving the outer buckle plate 202 to reset;

[0051] Secondly, the locking screws threaded on the cabinet 101 can fix the position of the long rod 402 on the lever 401, and then by adjusting the position of the lever 401, the hinge seat 201, the outer buckle plate 202 and the inner buckle plate 204 can be in a horizontal state as a whole. At this time, the ventilation slot 103 is opened, which can promote the high temperature in the cabinet 101 to be discharged from the ventilation slot 103 for heat dissipation.

[0052] like Figure 1 As shown:

[0053] The bottom surface of the cabinet 101 is fixedly connected to a mounting frame 104 by screws, and the electrical component assembly is fixedly mounted on the mounting frame 104 and is not in contact with the bottom surface of the cabinet 101, so as to facilitate heat dissipation of the electrical components;

[0054] The top surface of the cover plate 102 is provided with a mesh groove 105, which can also be used to store rainwater, thereby cooling the cover plate 102, so that the hot air flowing upward in the cabinet 101 contacts the low-temperature cover plate 102, which is convenient for cooling the inside of the cabinet 101; secondly, the cover plate 102 is provided with a plurality of protrusions, which increase the surface area of ​​the top surface of the cover plate 102, thereby promoting the dissipation of the high temperature on the top surface of the cover plate 102.
