[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] like Figure 1-4 As shown, a waterproof electrical control box comprises a cabinet body 1 fixed to the ground by a plurality of fixing components 3 and a cabinet door 2 installed at the front opening of the cabinet body 1 .

[0032] The outer walls on both sides of the cabinet 1 are fixedly connected with cooling pipe 1 4 and cooling pipe 2 6. Both ends of cooling pipe 1 4 and cooling pipe 2 6 pass through the cabinet 1, and the top ends of cooling pipe 1 4 and cooling pipe 2 6 are interconnected through a connecting pipe 5. An air pump 21 is fixedly installed on the connecting pipe 5, and the cabinet 1 is filled with insulating gas. The insulating gas can be an inert gas, sulfur dioxide, sulfur hexafluoride, etc., preferably sulfur hexafluoride.

[0033] After injecting insulating gas into the cabinet 1, the cabinet door 2 is installed on the cabinet 1, and then the air pump 21 is started to drive the gas flow in the cabinet 1. When the gas passes through the cooling pipe 1 4 and the cooling pipe 2 6, heat exchange is performed with the outside, and the cooled gas flows into the cabinet 1 again to form a cycle.

[0034] By injecting insulating gas into the cabinet 1 and utilizing the cooperation of the air pump 21, cooling tube 1 4 and cooling tube 2 6, the gas circulates in the cabinet 1 to avoid the risk of ionization breakdown due to excessive air content in the cabinet 1 when the wiring harness voltage is high, the distance between the wiring harnesses or the distance between the wiring harness and the cabinet 1 is close, thereby improving the safety of the device, and part of the cooling tube 1 4 and cooling tube 2 6 are arranged on the outside of the cabinet 1, which can achieve heat exchange with the outside when the gas passes through, thereby reducing the heat in the cabinet 1 and ensuring the normal operation of the electrical control box.

[0035] In this embodiment, a humidity sensor 8 is fixedly installed on the inner wall of the cabinet 1. By providing the humidity sensor 8, humidity information in the cabinet 1 can be obtained, so that it can be determined whether water has entered the cabinet 1 according to the humidity condition in the cabinet 1.

[0036] In this embodiment, the fixing assembly 3 includes a fixing plate 10 welded to the outer wall of the cabinet 1 and a rotating rod 11 rotatably connected to the inner wall of the fixing plate 10 .

[0037] The top outer wall of the rotating rod 11 is fixedly connected with a screw cap 9 , and the outer wall of the rotating rod 11 at the bottom of the fixing plate 10 is fixedly connected with an auger 12 .

[0038] The bottom end of the rotating rod 11 is brought into contact with the ground, and then the rotating cap 9 is rotated to drive the rotating rod 11 and the auger 12 to rotate underground until the bottom of the fixing plate 10 is in contact with the ground, thereby fixing the cabinet body 1.

[0039] By setting the screw cap 9 to drive the rotating rod 11 and the auger 12 to rotate underground, the cabinet 1 can be fixed more labor-savingly. The rotating rod 11 and the auger 12 are located underground. Even if there is a risk of electric shock in the cabinet 1, the current can be introduced into the underground in time, thereby reducing the risk of electric shock in the electrical control box.

[0040] In this embodiment, a plurality of connecting ears 13 are fixedly connected to the side wall of the cabinet door 2, a fixing block 15 adapted to the connecting ears 13 is welded to the outer wall of the cabinet body 1, the connecting ears 13 and the fixing block 15 are fixedly connected by bolts, and a sealing gasket 14 is provided on the opposite side of the cabinet body 1 and the cabinet door 2.

[0041] After aligning the connecting ear 13 and the fixing block 15, the cabinet door 2 is installed on the cabinet body 1 using bolts. The sealing gasket 14 between the cabinet body 1 and the cabinet door 2 can make the installation effect of the cabinet door 2 and the cabinet body 1 better, and can also prevent water and gas from entering the cabinet body 1 through the gap, thereby increasing the sealing of the electrical control box.

[0042] In this embodiment: first, insulating gas is filled into the cabinet 1, and then the connecting ear 13 is aligned with the fixing block 15, and the connecting ear 13 and the fixing block 15 are quickly connected using bolts, so that the cabinet door 2 is fixed to the cabinet 1, and then the cabinet 1 is placed in the specified position, and the screw cap 9 is rotated to drive the rotating rod 11 and the auger 12 to rotate until the bottom of the fixing plate 10 is in contact with the ground, thereby completing the installation and fixation of the cabinet 1, and finally starting the air pump 21 to drive the gas flow in the cabinet 1. On the one hand, the risk of ionization breakdown in the cabinet 1 is avoided, and on the other hand, with the coordinated use of cooling pipe 1 4, connecting pipe 5 and cooling pipe 2 6, the gas in the cabinet 1 forms a circulation, and when the gas passes through the pipes of cooling pipe 1 4 and cooling pipe 2 6 located outside the cabinet 1, the heat in the cabinet 1 is taken out, so as to cool the cabinet 1 and ensure the normal operation of the electrical control box.

[0043] Embodiment 2:

[0046] The terminal block 7 includes a threading plate 19 and a rubber sleeve 20. A flange plate 18 is welded to the side wall of the threading plate 19. The threading plate 19 is connected to the cabinet 1 by bolts. The flange plate 18 and the inner wall of the threading plate 19 are both provided with threading holes, and the rubber sleeve 20 is inserted into the threading holes.

[0047] The inner side of the rubber sleeve 20 is filled with foam rubber.

[0048] In this embodiment: the wiring harness in the cabinet 1 is passed through the rubber sleeve 20 and pulled out, and then the threading plate 19 is aligned with the avoidance groove 17, and then connected to the cabinet 1 using the flange plate 18, and then the extension length of the wiring harness is adjusted, and finally the gap between the wiring harness and the rubber sleeve 20 is filled with foam glue.

[0049] By setting the flange plate 18, the threading plate 19 and the rubber sleeve 20, the wiring harness in the cabinet 1 can be pulled out. After adjusting the extension length of the wiring harness, the gap between the rubber sleeve 20 and the wiring harness is filled with foam glue to prevent leakage of insulating gas in the cabinet 1 and improve the sealing of the electrical control box.
