For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] As Figures 1 to 4 shown, the present application provides a kind of convergence control cabinet, including outer cabinet body 1 and inner cabinet body 2, outer cabinet body 1 is provided with first door body 11, inner cabinet body 2 is provided with second door body 21, first door body 11 and second door body 21 are arranged on the same side of convergence control cabinet, electrical element is installed in the inside of inner cabinet body 2, inner cabinet body 2 is installed in outer cabinet body 1, outer cabinet body 1 and inner cabinet body 2 have waterproof function, outer cabinet body 1 can protect inner cabinet body 2 and electrical element in inner cabinet body 2, in the case where the second door body 21 of inner cabinet body 2 is not opened, rainwater cannot enter the inside of inner cabinet body 2, which can prevent electrical element from being damaged due to water.

[0029] The top of the inner cabinet 2 and the top of the outer cabinet 1 are spaced apart to form a containing cavity, a shielding assembly 3 is arranged in the containing cavity, the shielding assembly 3 is adjacent to the second door body 21, the side wall of the outer cabinet 1 and the upper surface of the inner cabinet 2 are inclined downward from the side close to the second door body 21 to the side away from the second door body 21, the outer side wall of the inner cabinet 2 is arranged spaced apart from the inner side wall of the outer cabinet 1 and forms a water collecting cavity, and the outer cabinet 1 is provided with a drain port 12 communicating with the water collecting cavity. When the power control cabinet needs to be overhauled, the first door body 11 is opened first, the shielding assembly 3 can extend from the top of the inner cabinet 2 to the outside of the outer cabinet 1, so that rainwater can be discharged out of the outer cabinet 1 along the shielding assembly 3, the upper surface of the inner cabinet 2, the water collecting cavity and the drain port 12 in turn, and the area adjacent to the second door body 21 of the inner cabinet 2 is shielded, providing an overhaul space for the staff that can prevent rain, preventing rainwater from entering the inner cabinet 2 from the second door body 21, meeting the needs of overhauling the power control cabinet in rainy weather, and improving the efficiency of overhauling.

[0030] It should be noted that the shielding assembly 3 can also shield sunlight in sunny weather, providing a more comfortable overhaul environment for the staff.

[0031] Preferably, the inclination of the upper surface of the inner cabinet 2 is 5%. This design not only ensures the flow efficiency of rainwater, but also allows most of the rainwater to flow along the side wall of the inner cabinet 2 from the upper surface of the inner cabinet 2, reducing the impact of rainwater on the side wall of the outer cabinet 1.

[0032] In the embodiment, as shown in Figure 2 and Figure 3 The shielding assembly 3 includes a waterproof cloth 31 and a clamping shaft 32, one end of the waterproof cloth 31 is fixedly arranged on the top of the inner cabinet 2 by bonding or clamping, etc., the other end is provided with the clamping shaft 32, the length of the clamping shaft 32 extends towards the width direction of the waterproof cloth 31, and the end of the clamping shaft 32 extends out of the waterproof cloth 31, the waterproof cloth 31 has an unfolded state and a rolled-up state, the clamping shaft 32 can roll up the waterproof cloth 31 on the top of the inner cabinet 2, so that the waterproof cloth 31 is in the rolled-up state and occupies a small space for storage; the top of the first door body 11 is recessed to form a clamping groove 111, which is an arc structure, when the first door body 11 is opened, the waterproof cloth 31 can be unfolded by pulling the clamping shaft 32, and the end of the clamping shaft 32 can be clamped in the clamping groove 111, so that the waterproof cloth 31 is located between the two first door bodies 11 and remains in the unfolded state, forming a semi-closed rain shelter structure.

[0033] In an embodiment, as shown in Figure 4As shown, the shielding assembly 3 is further provided with two fixing seats 33, the two fixing seats 33 are respectively arranged on opposite sides of the inner cabinet 2, a rotating shaft 34 is arranged between the two fixing seats 33, one end of the waterproof cloth 31 away from the shaft 32 is connected with the rotating shaft 34, the rotating shaft 34 is provided with an elastic element (not shown in the figure), the elastic element is a clockwork spring, the elastic element can always drive the rotating shaft 34 to rotate in the direction of winding the waterproof cloth 31, when the shaft 32 is removed from the clamping groove 111, the rotating shaft 34 can automatically wind the waterproof cloth 31 to the top of the inner cabinet 2, without manually winding the waterproof cloth 31, convenient to use, which is helpful to improve the work efficiency of the maintenance work.

[0034] Specifically, when the waterproof cloth 31 is in the unfolded state, the waterproof cloth 31 is inclined downward from the top of the first door body 11 to the top of the inner cabinet 2, which can guide the rainwater to the upper surface of the inner cabinet 2, which is helpful to quickly drain the rainwater.

[0035] Preferably, as Figure 1 As shown, the two ends of the shaft 32 are provided with a limiting nut 35, the limiting nut 35 is connected with the shaft 32 through threads, when the shaft 32 is clamped on the clamping groove 111, the limiting nut 35 can abut against the first door body 11 to fix the shaft 32, preventing the shaft 32 from being separated from the door body.

[0036] Specifically, the first door body 11 and the second door body 21 are both designed as double doors.

[0037] Specifically, the first door body 11 includes a first door and a second door, both the first door and the second door are provided with a clamping groove 111, both ends of the shaft 32 are provided with two limiting nuts 35, both ends of the shaft 32 are clamped on the first door and the second door respectively, and the opposite sides of the first door and the second door abut against the limiting nut 35. Since the first door body 11 is easy to be blown by the wind, the shaft 32 cannot be stably clamped in the clamping groove 111. This design can adjust the position of the two limiting nuts 35, so that the two limiting nuts 35 are clamped on the first door body 11, the two ends of the shaft 32 are fixed on the two first door bodies 11 respectively, forming a stable "H" type structure, the two first door bodies 11 are not easy to swing, which can ensure the stability of the waterproof cloth 31 during use.

[0038] In this embodiment, as Figures 2 to 5As shown, the bottom of the water receiving cavity is provided with a flow guide 4 which is sealingly abutted between the inner side wall of the outer cabinet 1 and the outer side wall of the inner cabinet 2. The top of the flow guide 4 is provided with a flow guide slope 41 which is inclined downward from the outer side wall of the inner cabinet 2 towards the inner side wall of the outer cabinet 1. The side wall of the outer cabinet 1 is provided with a drain 12 adjacent to the bottom, and the drain 12 is located above the abutment between the flow guide slope 41 and the outer cabinet 1. After the rainwater flows from the upper surface of the inner cabinet 2 to the water receiving cavity, the flow guide slope 41 of the flow guide 4 can quickly drain the rainwater to the drain 12 for discharge, and can also avoid the accumulation of rainwater in the outer cabinet 1. At the same time, the drain 12 has a certain distance from the ground, which can reduce the entry of foreign objects such as small animals into the outer cabinet 1.

[0039] Preferably, a blocking net (not shown in the figure) is arranged in the drain 12, which can further block the entry of foreign objects into the outer cabinet 1 from the drain 12.

[0040] Specifically, the outer cabinet 1 is provided with a drain 12 on the side wall perpendicular to the first door body 11 and the side wall away from the first door body 11, and each drain 12 is provided with a flow guide 4. Since part of the rainwater will flow down from the upper surface of the inner cabinet 2 along the two sides in the width direction, this design can discharge the rainwater on the two sides in the width direction of the inner cabinet 2 and the side of the inner cabinet 2 away from the second door body 21 outside the outer cabinet 1, avoid the accumulation of water in the outer cabinet 1, and improve the drainage efficiency.

[0041] Further, as shown in the figure, Figure 4 The flow guides 4 located on the two sides in the width direction of the inner cabinet 2 are provided with a baffle 42 which is arranged on the side of the flow guide 4 facing the second door body 21 and abutted between the outer side wall of the inner cabinet 2 and the inner side wall of the outer cabinet 1. The length of the baffle 42 extends towards the height direction of the inner cabinet 2. When the amount of rainwater accumulated at the flow guide slope 41 is greater than the drainage amount, the rainwater will flow towards the direction facing the second door body 21. By arranging the baffle 42, the rainwater can be blocked to prevent the rainwater from flowing to the second door body 21.

[0042] Specifically, as shown in the figure, Figures 1 to 3As shown, a blower assembly 5 is installed inside the outer cabinet 1. The blower assembly 5 includes a fan 51 and a power supply 52 connected to the fan 51. The fan 51 is located inside the receiving cavity, and the power supply 52 is located inside the inner cabinet 2. A cable pass-through hole 22 is provided through the top surface of the inner cabinet 2, through which the power cord of the fan 51 can pass and connect to the power supply 52. ​​A protective tube 6 is installed between the fan 51 and the inner cabinet 2 for the power cord. In this embodiment, the protective tube 6 is integrally formed with the side wall of the inner cabinet 2. The protective tube 6 surrounds the outer periphery of the cable pass-through hole 22, which can block rainwater flowing over the upper surface of the inner cabinet 2, prevent rainwater from entering the interior of the inner cabinet 2 through the cable pass-through hole 22 and damaging electrical components, and also protect the power cord from long-term impact from rainwater causing it to break. When the control cabinet is being repaired in rainy weather, the first door 11 is opened, and air convection is formed between the first door 11 and the drain outlet 12. The fan 51 can accelerate the airflow to keep the interior of the outer cabinet 1 dry.

[0043] Furthermore, such as Figure 5 As shown, in this embodiment, the blower assembly 5 also includes a controller (not shown) and a humidity sensor 53. The humidity sensor 53 and the power supply 52 are both connected to the controller. The humidity sensor 53 is installed on the inner wall of the outer cabinet 1 or the outer wall of the inner cabinet 2, and is used to detect the humidity inside the outer cabinet 1 to control the rotation of the fan 51. When the humidity inside the outer cabinet 1 exceeds a preset value, the controller can automatically control the fan 51 to start, so as to keep the inside of the outer cabinet 1 dry.

[0044] Specifically, such as Figure 6 As shown, the top of the outer cabinet 1 is provided with an air inlet 13, and the inner side of the top of the outer cabinet 1 is provided with an installation groove 14 communicating with the air inlet 13. The outer cabinet 1 is provided with a cover plate 7, which is slidably disposed in the installation groove 14. A rack 71 is provided on the side of the cover plate 7 facing the inside of the outer cabinet 1. A transmission gear 8 is also provided inside the outer cabinet 1. The transmission gear 8 is connected to a driving component and meshes with the rack 71. The transmission gear 8 can drive the cover plate 7 to slide in the installation groove 14. The cover plate 7 has a first position and a second position. When the cover plate 7 is in the first position, part of the cover plate 7 can move outside the installation groove 14 and block the air inlet 13 to prevent rainwater or foreign objects from entering the outer cabinet 1. When the cover plate 7 is in the second position, the cover plate 7 retracts into the installation groove 14, and air can enter the outer cabinet 1 from the air inlet 13, which can exhaust the heat inside the control cabinet and ensure the normal operation of the control cabinet.

[0045] It should be noted that during maintenance, since the first door 11 is open, air can smoothly enter the outer cabinet 1. Therefore, the cover 7 is in the first position, and rainwater will not enter the outer cabinet 1 from the air inlet 13. It can also dry the inside of the outer cabinet 1.

[0046] Specifically, the driving member is connected with the controller, the blowing assembly 5 further comprises a temperature sensor for detecting the temperature in the outer cabinet 1, when the temperature in the outer cabinet 1 exceeds a preset value, the driving member can drive the cover plate 7 to move to the second position, and the fan 51 is automatically started to automatically dissipate heat for the switch cabinet.
