[0040] The cable branch box is a device used for branching and connecting cables in power systems. Its main function is to branch or transfer cables, and it plays the role of cable branching and cable transfer.

[0041] The electrical equipment inside the cable branch box will generate a lot of heat during operation, especially high-voltage electrical equipment, which is prone to heat accumulation when working in a closed space. Therefore, it is necessary to install a cooling fan to increase internal air flow to dissipate heat. When the cable branch box is used outdoors, rainwater can easily penetrate the inside of the chassis through the dust filter, which can easily cause damage to the electrical equipment over time, thereby increasing the failure rate when used outdoors.

[0042] Based on this, the problem in the related technology can be improved. When the cable branch box is used outdoors, the ventilation holes and dust filters of the cable branch box make the inside of the chassis directly connected to the outside world. When it rains, rainwater can easily invade the inside of the chassis along the dust filter, which can easily cause damage to electrical equipment over a long period of time.

[0043] See also Figures 1-6 A cable branch box for outdoor use comprises an outer box body 1, an air inlet assembly 4 is provided at the outer end of the outer box body 1, a waterproof eaves 5 is fixedly connected to the top of the outer box body 1, a plurality of air outlet assemblies 6 are provided at the outer end of the waterproof eaves 5, the outer end of the outer box body 1 is rotatably connected to two box doors 2, the outer ends of the two box doors 2 are fixedly connected to handles 3, the air inlet assembly 4 comprises a shell 41, the shell 41 is fixedly connected to the outer end of the outer box body 1, the interior of the shell 41 is hollow, and a water baffle 44 is fixedly connected to the inner side wall of the shell 41, and the water baffle 44 is inclined.

[0044] The inner wall of the outer box body 1 is fixedly connected with fixed side frames 7 symmetrically arranged on both sides, and the outer ends of the fixed side frames 7 are provided with multiple ventilation holes.

[0045] A plurality of busbars 8 are fixedly installed between the two fixed side frames 7 , and a plurality of mounting cross frames 9 are fixedly installed between the two fixed side frames 7 . The busbars 8 and the mounting cross frames 9 are both located inside the outer box 1 .

[0046] Two threading plates 10 are fixedly connected to the bottom end of the outer box body 1. The two threading plates 10 are connected to each other by bolts, and the outer ends of the two threading plates 10 are provided with multiple threading holes arranged in a semicircle. The threading plates 10 are located below the mounting cross frame 9.

[0047] The interior of the outer box 1 in this solution is hollow and is used to install various electrical equipment. When installing the outer box 1, it is necessary to lift the outer box 1 off the ground. Box doors 2 are rotatably connected on both sides of the outer box 1. Since the device is mainly used for circuit branching and switching, the provision of two box doors 2 can facilitate the staff to connect the circuits on both sides. At the same time, two wire-threading plates 10 are fixed at the bottom end of the outer box 1. The wire-threading holes on the wire-threading plates 10 can realize the bottom entry and exit of the circuit, which can prevent the cable connectors from contacting the outside.

[0048] Fixed side frames 7 are fixed on both sides of the inner part of the outer box 1. The fixed side frames 7 are mainly used to install busbars 8 and installation cross frames 9. The installation cross frames 9 are mainly used to install electrical equipment, such as terminal blocks, circuit breakers and disconnectors. The busbars 8 are conductive materials on the cable branch box, usually made of flat copper or aluminum, and are mainly used for connection between power supplies. A waterproof roof 5 is fixed on the top of the outer box 1. The four sides of the waterproof roof 5 are equipped with air outlet components 6. The air outlet components 6 are mainly used for air outlet. The air intake component 4 has an intake fan 42 fixed on the outside of the shell 41, which is used to intake air into the chassis for heat dissipation. A water baffle 44 and an air guide plate 46 are fixed on the inside of the shell 41. When rainwater enters the inside of the shell 41, the rainwater will drip downwards and be absorbed by the absorbent cotton 43 through the obstruction of the water baffle 44 and its own gravity, while the air will enter the interior of the outer box body 1 along the internal U-shaped channel, thereby separating the rainwater from the air, preventing rainwater from entering the interior of the outer box body 1, and reducing the failure rate of electrical equipment.

[0049] Optionally, in some embodiments, see Figure 4 and Figure 5 The air intake assembly 4 also includes an air intake fan 42, which is fixedly mounted on the outer end of the shell 41. The inner side wall of the shell 41 is fixedly connected to an air guide plate 46, and the shell 41 is connected to the interior of the outer box 1.

[0050] Water-absorbing cotton 43 is installed inside the shell 41 and is located below the water baffle 44 . A filter screen 45 is installed between the air guide plate 46 and the water baffle 44 and is located above the water-absorbing cotton 43 .

[0051] The shell 41 is fixed to the side of the outer box 1, and the shell 41 is connected to the interior of the outer box 1. An air intake fan 42 is fixed to the outside of the shell 41. The air intake fan 42 is mainly composed of fan blades and a motor, which sucks the external air into the shell 41. The water baffle 44 is fixed to the inside of the shell 41 in an inclined shape, and the wind guide plate 46 is fixed to the inside of the shell 41 in a vertical shape. A filter 45 is provided between the water baffle 44 and the wind guide plate 46. The filter 45 is mainly used to block the external environment. When it rains, the water sucked in by the air intake fan 42 will first be blocked by the water baffle 44 and move downward by its own gravity. The absorbent cotton 43 installed at the bottom of the shell 41 will absorb the rainwater. At this time, the air will flow downward along the water baffle 44, and then be blocked by the wind guide plate 46, and will pass through the filter 45. The cooperation of the water baffle 44 and the wind guide plate 46 can form a U-shaped channel, thereby separating the rainwater from the air and preventing the rainwater from entering the interior of the outer box 1.

[0052] Optionally, in some embodiments, see Figure 6 The air outlet assembly 6 includes a front baffle 61 and a top baffle 62. A plurality of mounting grooves are provided at the outer end of the waterproof top eaves 5. The front baffle 61 and the top baffle 62 are fixedly connected to the inner wall of the mounting groove. A gap is provided between the front baffle 61 and the top baffle 62. An extension eaves 63 is fixedly connected to the outer end of the top baffle 62, and the extension eaves 63 is located above the front baffle 61.

[0053] The air outlet assembly 6 installed on the waterproof roof eaves 5 is mainly used to connect the interior of the outer box 1 with the outside world and discharge the hot air inside. The air outlet assembly 6 is arranged above the air inlet assembly 4. Since the density of hot air is less than that of cold air, the heat dissipation efficiency can be improved by entering from the bottom and exiting from the top. The front baffle 61 and the top baffle 62 are both fixed in the installation groove on the waterproof roof eaves 5, and a gap is left between them so that air can flow out. The extended eaves 63 fixed on the top baffle 62 extends to the outside, covering the gap between the front baffle 61 and the top baffle 62, preventing rainwater from entering, and improving the sealing.

[0054] Working principle: When installing the device, you first need to lift the outer box body 1 and install it off the ground. When the box doors 2 on both sides of the outer box body 1 are opened, the cable branching installation can be carried out, and the circuit can be allowed to enter and exit from the bottom through the wire holes on the wire board 10. When it rains, the water sucked in by the air intake fan 42 will first be blocked by the water baffle 44 and move downward by its own gravity, and the air will flow downward along the water baffle 44, and then be blocked by the wind guide plate 46 to pass through the filter 45. A U-shaped channel can be formed by the cooperation of the water baffle 44 and the wind guide plate 46, so that rainwater can be separated from the air. The air outlet component 6 on the waterproof roof eaves 5 is mainly used to connect the inside of the outer box body 1 with the outside world and discharge the hot air inside.

[0055] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
