[0044] As Figure 3 , Figures 9-12As shown, the electrical cabinet 110 is provided with a heat dissipation mechanism 30, the heat dissipation mechanism 30 comprises a wind box 310, a main pipe 320, a branch pipe one 321 and a branch pipe two 322, the wind box 310 is fixedly arranged above the electrical cabinet 110 through a connecting frame one 112, a fan is arranged in the wind box 310, the main pipe 320 is connected with the bottom of the wind box 310, the branch pipe one 321 and the branch pipe two 322 are connected with the main pipe 320, the air outlet of the branch pipe one 321 extends into the electrical cabinet 110 and is close to the electrical element 111, the air outlet of the branch pipe two 322 is close to the generator 131, a collecting box 350 is arranged above the wind box 310, the collecting box 350 is fixed between the top of the electrical cabinet 110 through a connecting frame two 113, the wind box 310 and the collecting box 350 are communicated through a communicating pipe 351, the collecting box 350 is communicated with an air inlet pipe 352, the fan can suck the air outside into the collecting box 350 and then circulate through the wind box 310, the main pipe 320, the branch pipe one 321 and the branch pipe two 322 in turn, so as to ventilate and dissipate heat for the electrical element 111 and the generator 131 in the electrical cabinet 110.
[0045] More specifically, the branch pipe one 321 and the branch pipe two 322 are respectively communicated with a control assembly one 330 and a control assembly two 340, the control assembly one 330 and the control assembly two 340 can control the air flow of the branch pipe one 321 and the branch pipe two 322 respectively, the armature 230 is connected with a trigger assembly, the trigger assembly comprises a displacement plate 270, a pressing plate 271 and a push plate 272, the bottom of the displacement plate 270 is fixedly connected with the side wall of the armature 230 and the other end penetrates through the top of the electrical cabinet 110, the pressing plate 271 and the push plate 272 are fixedly connected horizontally on the displacement plate 270, the push plate 272 is close to the control assembly one 330, and the pressing plate 271 is close to the control assembly two 340, when the output voltage of the generator 131 changes, the armature 230 moves up and down along the guide column one 220, so as to drive the displacement plate 270 to move up and down, thereby driving the pressing plate 271 and the push plate 272 to move up and down, then the pressing plate 271 and the push plate 272 can trigger the control assembly two 340 and the control assembly one 330 to work, so as to control the air flow of the branch pipe two 322 and the branch pipe one 321.
[0046] As Figures 9-11As shown, the control assembly one 330 and the control assembly two 340 have the same structure and each include a connecting housing 331, a limiting plate 332, a baffle 333 and a guide column two 335. The connecting housing 331 is connected to the branch pipe one 321 or the branch pipe two 322. The connecting housing 331 is a long rectangular cuboid with one side open. The baffle 333 is matched and inserted into the connecting housing 331 through the open end of the connecting housing 331. Vent holes 334 are formed on the baffle 333 and matched with the hole diameter of the branch pipe one 321 or the branch pipe two 322. The limiting plate 332 is arranged on the side wall of the connecting housing 331 and close to the open end of the connecting housing 331. The guide column two 335 is horizontally connected to the end of the baffle 333 through a connecting lug. The length direction of the guide column two 335 is parallel to the baffle 333. The end of the guide column two 335 passes through the limiting plate 332 and is provided with an external step. A spring two is sleeved on the guide column two 335. One end of the spring two is in contact with the connecting lug of the end of the baffle 333 and the other end is in contact with the limiting plate 332.
[0047] More specifically, the top surface of the push plate 272 is arranged in an inclined manner and close to the bottom edge of the baffle 333 on the control assembly one 330. The bottom surface of the pressing plate 271 is arranged in an inclined manner and close to the bottom edge of the baffle 333 on the control assembly two 340. The inclined length of the pressing plate 271 is greater than the inclined length of the push plate 272. When the output voltage of the generator 131 is large, the armature 230 moves upward along the guide column one 220, thereby driving the displacement plate 270 to move upward and then driving the push plate 272 to move upward. The top inclined surface of the push plate 272 abuts against the bottom edge of the baffle 333 on the control assembly one 330, thereby driving the baffle 333 to move along the guide column two 335, thereby separating the vent holes 334 on the baffle 333 from the hole diameter of the branch pipe one 321, thereby reducing the air exhaust amount of the branch pipe one 321. Therefore, the air exhaust amount of the branch pipe two 322 is increased, thereby increasing the ventilation and heat dissipation of the generator 131. When the output voltage of the generator 131 is small, the armature 230 moves downward along the guide column one 220, thereby driving the displacement plate 270 to move downward and then driving the pressing plate 271 to move downward. The bottom inclined surface of the pressing plate 271 abuts against the bottom edge of the baffle 333 on the control assembly two 340, thereby driving the baffle 333 to move along the guide column two 335. The inclined length of the pressing plate 271 is long, thereby separating the vent holes 334 on the baffle 333 from the hole diameter of the branch pipe two 322, thereby closing the air exhaust of the branch pipe two 322. The air exhaust amount of the branch pipe one 321 is increased, thereby increasing the ventilation and heat dissipation of the electrical element 111.
[0048] More specifically, the voltage of the generator 131 changes slightly, which does not affect the normal operation of the generator 131, and the marking plate 260 does not need to be moved to mark the line, therefore, the installation housing one 233 and the installation housing two 234 are provided with blank areas 237, the tooth block 252 on the rotating shaft 251 is between the blank area 237 of the installation housing one 233 and the blank area 237 of the installation housing two 234, the moving range of the armature 230 along the guide column one 220 is small, so that the rotating shaft 251 does not rotate, and the marking plate 260 does not move.
[0049] More specifically, the collecting box 350 is matched with a cover plate 353, and the air inlet port of the communication pipe 351 is matched with a filter plate 354, so as to filter the impurities in the air, and the filtered impurities are in the collecting box 350.

[0051] In use, when the output voltage of the generator 131 changes, the electromagnet 210 changes the attraction force on the armature 230, thereby driving the armature 230 to move up and down along the guide column 220, thereby driving the marking pen 231 to move up and down, when the armature 230 moves up along the guide column 220, the tooth block 252 at the end of the rotating shaft 251 is in transmission cooperation with the inclined block 235, when the armature 230 moves down along the guide column 220, the tooth block 252 at the end of the rotating shaft 251 is in transmission cooperation with the inclined block 236, and in the transmission process, the rotating shaft 251 rotates in the same direction, then the rotating shaft 251 drives the gear 253 to rotate, thereby driving the rack 256 to move along the guide rod 255, thereby driving the marking plate 260 to move along the guide rod 255, in the moving process of the marking pen 231, the surface of the marking plate 260 can be marked by moving and drawing lines, thus the moving change of the armature 230 can be observed, thereby the output voltage change of the generator 131 can be judged, thereby whether the output voltage of the generator 131 is abnormal can be observed, when the marking trace of the marking pen 231 exceeds the standard range, the output voltage of the generator 131 is abnormal, when the output voltage of the generator 131 is large, the armature 230 moves up along the guide column 220, thereby driving the displacement plate 270 to move up, then driving the push plate 272 to move up, the top inclined surface of the push plate 272 abuts against the bottom edge of the baffle 333 on the control assembly one 330, thereby making the baffle 333 move along the guide column two 335, thereby making the air vent hole 334 on the baffle 333 dislocate with the hole diameter of the branch pipe one 321, thereby making the exhaust amount of the branch pipe one 321 decrease, thus the exhaust amount of the branch pipe two 322 increases, thereby increasing the ventilation and heat dissipation of the generator 131, when the output voltage of the generator 131 is small, the armature 230 moves down along the guide column 220, thereby driving the displacement plate 270 to move down, then driving the pressing plate 271 to move down, the bottom inclined surface of the pressing plate 271 abuts against the bottom edge of the baffle 333 on the control assembly two 340, thereby making the baffle 333 move along the guide column two 335, the inclined length of the pressing plate 271 is long, thereby making the air vent hole 334 on the baffle 333 separate from the hole diameter of the branch pipe two 322, thus the exhaust of the branch pipe two 322 can be closed, the exhaust amount of the branch pipe one 321 increases, thereby increasing the ventilation and heat dissipation of the electrical element 111, the air inlet port of the communication pipe 351 is matched with the filter plate 354, thereby filtering the impurities in the air, the filtered impurities are in the collection box 350, opening the cover plate 353 can clean the impurities.
