[0083] The principle of the present invention is described as follows: For an effectively heat dissipating and moisture-proof electric control cabinet, during application, through the compression spring 26, the left half cylinder body 27, the right half cylinder body 271, the left half housing 29 and the right half housing 291 are all in an open state, which facilitates the staff to install or repair electronic components. Then, through the operation of the motor 14, the two half cylinder bodies and the half housings move closer to fit. At this time, the setting of the round beads can effectively reduce the frictional resistance, making it easier for the two half cylinder bodies and the two half housings to fit; moreover, when the electric cabinet is working, through the operation of the motor 14, the rotating shaft 10 drives the fan blades 7 to rotate, generating a large amount of wind through the rotation of the fan blades. Then, the wind blows into the half cylinder body through the first through hole 8, effectively dissipating heat and cooling the electronic components. At the same time, through the setting of the gear 4 and the semi-tooth ring 23, the two half cylinder bodies are rotated, and thus the position of the first through hole 8 locally provided on the side wall is moved. In this way, moving the first through hole 8 changes the direction of the blown wind, so that the wind can dissipate heat from all directions to the internal electrical components, further effectively extending the service life of the electrical components. The heat-dissipated wind flows through the gaps between the moisture absorption materials 2 and is then discharged to the outside through the exhaust holes 37. In this way, the drying balls can be effectively dried, keeping the moisture absorption material 2 always dry and preventing moisture from entering the cabinet body through the exhaust holes 37.

The shelving device 38 includes a left half cylinder 27, a right half cylinder 271, a left half cover 29, a right half cover 291 and an air outlet pipe 19. The left half cylinder 27 and the right half cylinder 271 are butted to form a cylindrical body with an open upper end. A plurality of first through holes 8 are respectively arranged on the side walls of the left half cylinder 27 and the right half cylinder 271. The left half cover 29 is arranged on the top of the left half cylinder 27. The right half cover 291 is arranged on the top of the right half cylinder 271. The left half cover 29 and the right half cover 291 are butted to form a hollow hemisphere. The top of the left half cylinder 27 is embedded in the bottom of the left half cover 29 and is rotationally connected. The top of the right half cylinder 271 is embedded in the bottom of the right half cover 291 and is rotationally connected. A plurality of round beads 22 (preferably movably arranged) are arranged at the bottoms of the left half cylinder 27 and the right half cylinder 271. The bottoms of the round beads 22 are in contact with the top surface of the bottom box 1. Exhaust holes 3 are arranged on the top surface of the bottom box 1 at the left side of the left half cylinder 27 and the right side of the right half cylinder 271. A moisture-absorbing material 2 is filled in the bottom box cavity 39 in the bottom box 1. A feeding port 37 communicating with the bottom box cavity 39 is arranged on the top of the bottom box 1. A left vertical plate 28, a right vertical plate 281, an upper support plate 17 and a lower support plate 171 are arranged in the shelving device 38. The top end of the left vertical plate 28 is connected to the top end of the right vertical plate 281 through the upper support plate 17. The bottom end of the right vertical plate 281 is connected to the bottom end of the left vertical plate 28 through the lower support plate 171. The left vertical plate 28, the upper support plate 17, the right vertical plate 281 and the lower support plate 171 together enclose a containing chamber 40. At least one storage box 41 is arranged in the containing chamber 40. The storage box 41 includes a top box plate 411 and a bottom box plate 412. The left ends of the top box plate 411 and the bottom box plate 412 are both connected to the middle of the left vertical plate 28. The right ends of the top box plate 411 and the bottom box plate 412 are both connected to the middle of the right vertical plate 281.

[0086] During application, the left half cylinder body 27 and the right half cylinder body 271 are slid open and closed through the spherical beads 22 arranged at the bottom, which is convenient for taking and placing electrical equipment. The storage box 41 in the shelving device 38 can be freely adjusted and matched according to the size of the electrical equipment. After the cabinet body is closed, the air in the cabinet body freely circulates through the first through hole 8, the second through hole 9, the air outlet pipe 19 and the bottom box cavity 39. The moisture in the air is adsorbed by the moisture absorption material 2 arranged in the bottom box cavity 39 and finally flows out through the exhaust hole 3, thus ensuring the dryness in the cabinet body. The left half cylinder body 27, the right half cylinder body 271 and the left half cover body 29, the right half cover body 291 cooperate with each other to rotate, and the spherical beads 22 arranged at the bottom reduce the friction force, realizing the rotation of the cabinet body, enabling the air to further flow, and further enhancing the heat dissipation of the cabinet body.

One end of the fixing plate 12 is fixedly connected to the vertical plate of the left L-shaped arc plate 11, and the other end of the fixing plate 12 is sleeved with a sleeve 13. The sleeve 13 is rotatably connected to the fixing plate 12 in a fitting manner, and the sleeve 13 is rotatably connected to the rotating shaft 10 in a fitting manner. Two circular rings 33 are fixedly connected to the sleeve 13, and the circular rings 33 are respectively in fitting connection with the top surface and the bottom surface of the fixing plate 12. Two retaining rings 5 are fixedly arranged on the rotating shaft 10, and the retaining rings 5 are respectively in fitting connection with the top surface and the bottom surface of the left semi-circular cover 6. A first through hole 31 is provided on the side wall at the lower end of the sleeve 13. A second through hole 32 is provided on the side wall at one end of the fixing plate 12. The top end of the outer side wall of the left vertical plate 28 is fixedly connected to a second sliding rod 30. The top end of the outer side wall of the right vertical plate 281 is fixedly connected to a third sliding rod 301.

[0091] One end of the second sliding rod 30 is fixedly connected to the outer side wall of the left vertical plate 28, and the other end of the second sliding rod 30 slides through the left half cover 29 and extends towards the left L-shaped arc plate 11. One end of the third sliding rod 301 is fixedly connected to the outer side wall of the right vertical plate 281, and the other end of the third sliding rod 301 slides through the right half cover 291 and extends towards the left L-shaped arc plate 111. A first fixing ring 16 is fixedly arranged in the left half cover 29. A second fixing ring 161 is fixedly arranged in the right half cover 291. Third through holes 15 are provided on both the left half cover 29 and the right half cover 291. Steel wire ropes 35 are arranged on both the left transmission module 42 and the right transmission module 421. The winding roller 34 is fixedly connected to the sleeve 13, and the winding roller 34 is wound with the steel wire rope 35. The steel wire rope 35 on the left transmission module 42 passes through the third through hole 15 on the left half cover 29 and extends into the right half cover 291 to be connected to the second fixing ring 161. The steel wire rope 35 on the right transmission module 421 passes through the third through hole 15 on the right half cover 291 and extends into the left half cover 29 to be connected to the first fixing ring 16. A plurality of fans 7 are fixedly connected to the rotating shaft 10, and the fans 7 are arranged in the left semi-circular cover 6 and the right semi-circular cover 61.

[0092] During application, the compression springs 26 inside the left and right cylinders 36 and 361 push the slider 25 and the first slide rod 24, pushing open the left half cylinder body 27 and the right half cylinder body 271, thereby achieving a more convenient opening of the cabinet body and facilitating the installation and maintenance of electrical devices. When closing the cabinet body, loosen the bolt in the second through hole 32 so that the fixing plate 12 and the sleeve 13 are in a fitting rotational connection. Then start the motor 14 to operate, so that the output end drives the rotating shaft 10 to rotate. At this time, the rotating shaft 10 and the sleeve 13 are fixedly connected by the bolt in the first through hole 31. Thus, the rotating shaft 10 drives the sleeve 13 and the winding roller 34 to rotate synchronously, causing the steel wire rope 35 to wind around the winding roller 34. At this time, under the guidance of the second slide rod 30 and the third slide rod 301, the steel wire rope 35 pulls the two half covers to approach and fit each other. Thus, the half cover drives the half cylinder body to move synchronously. During the movement of the half cylinder body, the spherical beads 22 on the bottom surface of the half cylinder body can effectively reduce the frictional resistance, making it easier for the two half cylinder bodies and the two half covers to fit. When the two half cylinder bodies and the two half covers are fitted, stop the operation of the motor 14. Then loosen the bolt in the first through hole 31 so that the rotating shaft 10 and the sleeve 13 are in a fitting rotational connection to prevent the sleeve 13 from rotating with the rotating shaft 10. Then fix the fixing plate 12 and the sleeve 13 together by the bolt in the second through hole 32 to fix the sleeve 13 and prevent the steel wire rope 35 from pulling the winding roller 34 to rotate. Start the motor 14 to operate again, driving the rotating shaft 10 to rotate. During the rotation of the rotating shaft 10, the rotating shaft 10 drives the fan blades 7 to rotate synchronously. A large amount of wind is generated by the rotation of the fan blades 7, and then the wind blows into the half cylinder body through the first through hole 8, effectively dissipating heat and cooling the electronic components. At the same time, the rotating shaft 10 drives the gear 4 to rotate synchronously. At this time, the gear 4 is meshed with the half tooth ring 23, causing the two half cylinder bodies to rotate. By rotating the half cylinder body, the position of the first through hole 8 provided locally on the side wall of the half cylinder body is moved. In this way, moving the first through hole 8 changes the direction of the blown wind. Thus, the wind generated by the rotation of the fan blades 7 can dissipate heat from the internal electrical components in all directions. The heat-dissipated wind enters the bottom box 1 through the air outlet pipe 19. At this time, the wind flows through the gaps between the moisture-absorbing materials 2 and then is discharged to the outside through the exhaust holes 3 provided on the bottom box 1. In this way, the moisture-absorbing materials 2 can be effectively dried, and thus the moisture-absorbing materials 2 can always be kept dry, preventing moisture from entering the half cylinder body through the exhaust holes 3.

[0094] The basic content is the same as that of Embodiment 2, with the difference being that:

[0095] A plug-and-play structure (preferably a bolt or a pin) is provided in the first through hole 31 and the second through hole 32.

[0096] During application, the plugging and unplugging structure can freely adjust the fit between the first through hole 31 and the sleeve 13, and between the second through hole 32 and the fixing plate 12, so as to realize the free connection between components.

[0097] Embodiment 4:

[0098] The basic content is the same as that of Embodiment 2, the difference is that:

[0099] The central axes of the wire winding roller 34, the steel wire rope 35, the third through hole 15 and the second fixing ring 161 of the left transmission module 42 are on the same straight line; the central axes of the wire winding roller 34, the steel wire rope 35, the third through hole 15 and the first fixing ring 16 of the right transmission module 421 are on the same straight line.

[0100] During application, the wire winding roller 34 drives the steel wire rope 35 to pull the second fixing ring 161, and then drives the cabinet body to close, which is beneficial to ensuring the stability of the cabinet body during operation.
