[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. The control cabinet can display various parameters during operation with the help of measuring instruments, and can also adjust certain electrical parameters, and give prompts or send signals when they deviate from the normal working state. Control cabinets in outdoor environments are prone to moisture or water ingress when encountering rainy weather, causing short circuits in internal components and other faults. Therefore, the control cabinet needs to be moisture-proofed.

[0003] For example, a moisture-proof control cabinet disclosed in the utility model with authorization announcement number CN215497713U can reduce the impact force of external forces on internal components and protect the control cabinet from deformation and damage by using shock-absorbing springs in conjunction with mounting plates, anti-collision plates and buffer cotton. By arranging support columns, rain guide roofs, reeling shafts and rain shields, rainwater can be conveniently guided down along the rain guide roof to prevent rainwater from entering the interior of the control cabinet.

[0004] This prior art also has the following problems when used:

[0005] The device controls the reel to drive the rain shield to cover the side of the control cabinet, thereby preventing rain from entering the interior of the control cabinet. However, when the wind is strong on rainy days, the wind can easily drive the rain shield to detach from the side of the control cabinet, causing rain to enter the interior of the control cabinet, thereby reducing the moisture-proof effect of the rain shield.

[0027] like Figure 1-Figure 5As shown, a rolling curtain assembly is arranged on the back of the control cabinet 1, and the rolling curtain assembly consists of a nylon rope 8, a winding drum 13, a connecting block 15, a pulley 16 and a first T-shaped slider 17. The winding drum 13 and the pulley 16 are fixedly installed on the back of the control cabinet 1, and a winding shaft is fixedly arranged between the inner walls on the left and right sides of the winding drum 13. A rain shield 14 is arranged on the periphery of the winding shaft, and the rain shield 14 passes through the winding drum 13. The winding shaft can automatically roll up the rain shield 14. A symmetrical connecting block 15 is fixedly arranged on the bottom surface of the rain shield 14, and a nylon rope 8 is fixedly arranged on the bottom surface of the connecting block 15. The nylon rope 8 is sleeved on the outside of the pulley 16.

The first T-shaped slider 17 is slidably connected to the control cabinet 1 through the first T-shaped groove. When it rains, the end of the nylon rope 8 away from the connecting block 15 moves upward to drive the connecting block 15 to move downward, thereby driving the rain shield 14 to extend downward to cover the back side of the control cabinet 1. The limiting position of the rain shield 14 by the rolling curtain assembly can prevent the wind from changing the position of the rain shield 14, and prevent rainwater from entering the interior of the control cabinet 1 through the air inlet net 7, thereby improving the moisture-proof effect of the rain shield 14.

[0028] like Figure 1-Figure 5 As shown, a folding assembly is arranged on the top of the control cabinet 1, and the folding assembly consists of a top cover 3, a rain guide plate 4, a baffle 5, a hydraulic cylinder 6, a second T-shaped slider 11 and a second T-shaped slide 12. The hydraulic cylinder 6 is fixedly installed on the top surface of the control cabinet 1, and the top cover 3 is fixedly installed on the top surface of the output end of the hydraulic cylinder 6. A raindrop sensor 9 is fixedly installed on the top surface of the top cover 3, and the raindrop sensor 9 can monitor rain and rainfall. Symmetrical rain guide plates 4 are arranged below the front and rear sides of the top cover 3, and the bottom of the rain guide plates 4 is hinged to the top surface of the control cabinet 1. Symmetrical baffles 5 are fixedly arranged on the left and right sides of the top cover 3. The bottom surface of the baffle 5 is fixedly connected to the end of the nylon rope 8 away from the connecting block 15, the top surface of the rain guide plate 4 is hinged with a second T-shaped slider 11, and the bottom surface of the top cover 3 is provided with a symmetrical second T-shaped slot 12. The second T-shaped slider 11 is adapted to the second T-shaped slot 12, and the second T-shaped slider 11 is slidingly connected to the top cover 3 through the second T-shaped slot 12. The folding component can guide rainwater when it rains while driving the rain curtain 14 to extend downward. After the folding component is folded, the center of gravity can be lowered, thereby improving the stability of the control cabinet 1, and the space occupied by the folding component can be reduced by folding.

[0029] Specifically, when the raindrop sensor 9 detects rain, the raindrop sensor 9 transmits an electrical signal to the control panel 10, and the control panel 10 controls the operation of the hydraulic cylinder 6 to drive the top cover 3 to move upward, and the top cover 3 moves downward to drive the baffle 5 to move upward, and at the same time, the second T-shaped sliders 11 move away from each other along the second T-shaped slide groove 12, and the second T-shaped sliders 11 move in the second T-shaped slide groove 12 to drive the rain guide plate 4 to rotate until the top cover 3 moves to the highest position, and the top cover 3 and the rain guide plate 4 cooperate with the baffle 5 to guide the rainwater to prevent the rainwater from contacting the outer wall of the control cabinet 1, and the baffle 5 moves upward while driving the nylon rope 8 away from the connecting block 15 to move upward, thereby driving the rain curtain 14 to extend downward to cover the air intake net 7.

[0030] Specific working principle:

[0031] The exhaust fan of the device cooperates with the air intake net 7 to ventilate and dissipate heat inside the control cabinet 1. When the raindrop sensor 9 detects rain, the raindrop sensor 9 transmits an electrical signal to the control panel 10. The control panel 10 controls the hydraulic cylinder 6 to drive the top cover 3 to move upward, and the top cover 3 moves downward to drive the baffle 5 to move upward. At the same time, the second T-shaped slider 11 moves away from each other along the second T-shaped slide groove 12. The second T-shaped slider 11 moves in the second T-shaped slide groove 12 to drive the rain guide plate 4 to rotate until the top cover 3 moves to the highest position, thereby guiding the rainwater and preventing the rainwater from contacting the outer wall of the control cabinet 1. When the baffle 5 moves upward, it drives the end of the nylon rope 8 away from the connecting block 15 to move upward, thereby driving the rain shield 14 to extend downward to cover the air intake net 7. The limit of the rain shield 14 by the rolling curtain assembly can prevent the wind from changing the position of the rain shield 14, prevent rainwater from entering the control cabinet 1 through the air intake net 7, and improve the moisture-proof effect of the rain shield 14.

[0032] The control panel 10 controls the operation of the hydraulic cylinder 6 to drive the top cover 3 to move downward to its original position, so that the folding assembly can be folded, thereby lowering the center of gravity and improving the stability of the control cabinet 1. The space occupied by the folding assembly can be reduced by folding. The top cover 3 moves downward, driving the baffle 5 to move downward, and the winding shaft drives the rain curtain 14 to automatically wind up in the winding drum 13.
