[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] Reference Figure 1-10 The utility model discloses an outdoor power distribution control cabinet, including a cabinet body 1. A closed distribution room 2 is arranged inside the cabinet body 1. Heat dissipation mechanisms 8 are arranged at the four corners of the distribution room 2. The heat dissipation mechanism 8 includes heat dissipation ground piles 4 that penetrate downwardly through the cabinet body 1. The heat dissipation mechanism 8 takes away heat through the heat dissipation ground piles 4.

[0035] Distribution switches and instruments are installed in the distribution room 2. The front end of the distribution room 2 is open, and a cabinet door 3 is installed at the front end of the distribution room 2. A sealing strip is installed in the gap between the cabinet door 3 and the distribution room 2 to form a sealed structure for the distribution room 2. The closed structure of the distribution room 2 can prevent external heat from entering the interior of the distribution room 2 and can also achieve the effect of dustproof and waterproof.

[0036] In order to further reduce the heat transfer of the cabinet 1 , the surface of the cabinet 1 may be covered with heat insulation cotton.

[0037] Generally speaking, to improve the stability of the installation of the cabinet 1, one is to build a foundation, and the other is to use ground piles for fixing. However, the foundation is generally made of concrete, but the concrete foundation mainly has a cooling process, and the ground pile fixation is faster in construction speed.

[0038] The heat dissipation piles 4 in the present application not only fix the cabinet 1, but also have a heat dissipation function, combining heat dissipation and fixation.

[0039] The heat dissipation piles 4 are arranged at the four corners of the distribution room 2 . An arc plate 9 is arranged on one side of the heat dissipation pile 4 close to the center of the distribution room 2 . A heat dissipation fan 13 is arranged between one end of the arc plate 9 and the side wall of the distribution room 2 .

[0040] The top of the heat dissipation ground pile 4 and the arc plate 9 are connected to the top of the power distribution room 2 , and the bottom of the arc plate 9 is connected to the bottom of the power distribution room 2 .

[0041] After the distribution switches and instruments are installed in the distribution room 2, the cooling fan 13 blows the cold air from the cooling piles 4 to the distribution switches and instruments for heat dissipation, adopting an active heat dissipation method, which has higher heat dissipation efficiency than the prior art.

[0042] The side walls of the distribution room 2, the heat dissipation ground piles 4, and the arc plate 9 are all provided with intervals. One end of the arc plate 9 is connected to the distribution room 2 through the first support rod 10, and the other end is connected to the distribution room 2 through the second support rod 11. The heat dissipation ground piles 4 are connected to the distribution room 2 through the third support rod 12. The first support rod 10, the second support rod 11, and the third support rod 12 are all arranged at intervals.

[0043] The side walls of the distribution room 2, the heat dissipation piles 4, and the gaps between the arc plates 9 form an air duct. The hot air in the distribution room 2 enters from one side of the arc plate 9, flows through the surface of the heat dissipation piles 4 for cooling, and is then blown toward the distribution switches and instruments by the heat dissipation fan 13, forming a circulating heat dissipation airflow.

[0044] A cooling fan 13 is installed between two adjacent first support rods 10 .

[0045] The first support rod 10 serves as a supporting structure for the arc plate 9 and the heat dissipation fan 13, so that the heat dissipation fan 13 can draw air in the air duct from different height positions of the arc plate 9 to reduce air leakage.

[0046] The cross-section of the arc plate 9 is fan-shaped, and the axis of its center is in the vertical direction. The arc plate 9 protrudes toward the side close to the heat dissipation pile 4, so that the tangent of the arc plate 9 close to the second support rod 11 is parallel to the side wall of the distribution room 2, and the angle between the tangent of the arc plate 9 close to the third support rod 12 and the other side of the distribution room 2 is 30 degrees to 70 degrees.

[0047] The angle of the included angle is preferably 45 degrees. Figure 3 , 4 As shown, hot air flows in from the side of the arc plate 9 close to the second support rod 11, bypasses the surface of the heat dissipation pile 4, and flows out from the end close to the third support rod 12, and flows toward the center of the distribution room 2 when flowing out, so that more air can be blown onto the distribution switches and instruments.

[0048] The heat dissipation ground pile 4 includes an upper rod body 5 extending upward into the inside of the power distribution room 2 , a lower rod body 6 is arranged at the bottom of the upper rod body 5 , and the upper rod body 5 and the lower rod body 6 are movably connected via a connecting sleeve 7 .

[0049] Before installation, the upper rod body 5 is separated from the lower rod body 6 for easy transportation and carrying. During installation, the lower rod body 6 is first inserted into the ground, and then the connecting sleeve 7 is installed on the top of the lower rod body 6. Finally, the bottom of the upper rod body 5 is connected to the top of the connecting sleeve 7 to fix the cabinet 1.

[0050] A first partition 16 is provided inside the upper rod body 5, and a communication port 17 is provided on the top of the first partition 16. The first partition 16 divides the interior of the upper rod body 5 into a first channel 14 and a second channel 15. The first channel 14 and the second channel 15 are connected through the communication port 17.

[0051] A second partition 18 is provided inside the lower rod body 6 and is connected to the first partition 16. A circulating pump 20 is embedded in the bottom of the second partition 18. The first partition 16 divides the interior of the lower rod body 6 into a third channel 19 and a fourth channel 21. The inlet end of the circulating pump 20 is located in the third channel 19, and the outlet end is located in the fourth channel 21.

[0052] After the first partition 16 is connected to the second partition 18, the first channel 14 is connected to the third channel 19, and the second channel 15 is connected to the fourth channel 21. The circulation pump 20 sends the cold air in the third channel 19 into the fourth channel 21, enters the second channel 15 through the fourth channel 21, and then enters the first channel 14 from the connecting port 17, and finally flows back to the third channel 19 to form a circulation loop.

[0053] The cooling fan 13 blows the cold air in the first channel 14 and the second channel 15 to the distribution switch and the instrument through the surface of the upper rod body 5, and the heat of the hot air in the distribution room 2 is taken away by the air in the first channel 14 and the second channel 15 through the surface of the upper rod body 5.

[0054] The connecting sleeve 7 includes an inner sleeve 25 with the same diameter as the upper rod body 5 and the lower rod body 6. Both ends of the inner sleeve 25 are provided with outer sleeves 22. The ends of the two outer sleeves 22 that are close to each other are movably connected with the outer sleeves 22, and the ends of the two outer sleeves 22 that are away from each other are respectively screwed with the ends of the upper rod body 5 and the lower rod body 6.

[0055] See Fig. 9 , 10 The outer sleeve 22 is movably connected with the inner sleeve 25. The outer sleeve 22 is sleeved on the outside of the inner sleeve 25. The outer sleeve 22 can slide axially in the inner sleeve 25 and rotate radially at the same time. A thread of corresponding specifications is processed between the inside of one end of the outer sleeve 22 away from each other and the bottom outside of the upper rod body 5 and the top outside of the lower rod body 6.

[0056] Sealing rings can be installed at both ends of the inner sleeve 25 to seal the upper rod body 5 and the lower rod body 6 to prevent air leakage.

[0057] When in use, the lower rod body 6 is installed first, and then the lower outer sleeve 22 is screwed to the lower rod body 6 , and then the upper outer sleeve 22 is screwed to the bottom of the upper rod body 5 .

[0058] A third partition plate 23 is disposed inside the inner sleeve 25 , and partition plate slots 24 corresponding to the first partition plate 16 and the second partition plate 18 are respectively formed at both ends of the third partition plate 23 .

[0059] During installation, first snap the partition slot 24 at the bottom of the third partition 23 into the top of the second partition 18. At this time, the bottom of the inner sleeve 25 is also docked with the top of the lower rod 6. Then, screw the lower outer sleeve 22 to screw it into the lower rod 6. Then snap the partition slot 24 at the top of the third partition 23 into the bottom of the first partition 16. The top of the inner sleeve 25 is also docked with the bottom of the upper rod 5. Finally, screw the upper outer sleeve 22 to screw it into the upper rod 5.

[0060] Working principle: During installation, first insert the lower rod body 6 into the ground so that the tops of the four lower rod bodies 6 are at the same height, then install the connecting sleeve 7 on the lower rod body 6, and finally connect the bottom of the upper rod body 5 to the connecting sleeve 7.

[0061] When heat dissipation is required, the cooling fan 13 and the circulating pump 20 are started. The circulating pump 20 transports the cold air from the underground upward to the inside of the distribution room 2 through the heat dissipation ground piles 4. The cooling fan 13 blows the cold air on the surface of the heat dissipation ground piles 4 to the distribution switches and instruments in the distribution room 2. The air heat in the distribution room 2 is taken away by the heat dissipation ground piles 4 and dissipated into the ground.
