Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example 1, as Figure 1 As shown in Figure 2, this embodiment discloses a sealed waterproof central control box, including a box body 1 and a cover 2. A control board 3 is installed at the bottom of the box body. The control board is the main functional component, containing various electronic components, mainly used for data storage, acquisition, analysis, and processing. An input socket 4 and an output socket 5 are provided on the side of the box body. The control board is electrically connected to the input socket via an input cable 6 and to the output socket via an output cable 7. The input socket and output socket are used for data input and output, respectively. External data can be imported into the control board through the input socket via the cable, and data processed by the control board can be exported through the output socket. A frame 22 is welded to the top of the box body. A sealing groove 27 is provided around the edge of the frame, and a sealing ring 8 is placed in the sealing groove. The cover is fastened to the top of the box body and fixed to the frame with bolts. The cooperation between the cover, the sealing ring, and the sealing groove ensures the waterproofness of the central control box.

[0025] The box body is sheet metal part 21, which is formed by bending the sheet metal. The material is rust-proof aluminum alloy with a thickness of 2mm. Before bending, the press-fit studs and waterproof nuts must be installed. The frame is made of rust-proof aluminum alloy with a thickness of 8mm. The cover is made of rust-proof aluminum alloy with a thickness of 3mm.

[0026] like Figure 3 As shown, four press-fit studs 23 are installed on the bottom surface of the box. The threaded holes in the press-fit studs are blind holes with a depth of not less than 6mm. Four pan head screws 13 are used in conjunction with the four press-fit studs to fix the control board to the bottom of the box.

[0027] Two through holes 24 and eight waterproof nuts 25 are provided on the side surface of the box body. The input socket and the output socket are inserted into the two through holes described above and are respectively fixed to the side surface of the box body with four waterproof nuts. The threaded holes inside the waterproof nuts are blind holes, and the depth of the blind holes is not less than 6 mm. A waterproof gasket 10 is also provided at the joint surface between the box body and the input socket and the output socket, which plays a role in sealing to prevent water from entering the inside of the box body. The waterproof gasket is made of conductive silica gel with a thickness of 1 mm, which not only ensures the electromagnetic shielding performance but also ensures the waterproof performance.

[0028] To ensure the sealing performance of the box body, the welding form between the frame and the box body is full welding. After welding, the surface of the welding part is polished and smoothed.

[0029] The frame is roughly in the shape of a "hui" character. A number of threaded holes 26 are provided between the edge of the frame and the sealing groove, that is, the threaded holes are arranged outside the sealing groove. The threaded holes are blind holes with a depth of 6 mm, and wire thread inserts are embedded in the holes.

[0030] As Figure 4 shown, a groove 28 with a depth of 1 mm is provided on the bottom surface of the gland. The roughness of the groove is less than 3.2 um. Fixed holes 30 with the same number and opposite positions as the above-mentioned threaded holes are also provided on the gland. The fixed holes are counterbored holes. The gland and the box body are fixed together with a countersunk screw 9 passing through the fixed holes and the threaded holes.

[0031] Four waterproof nuts 29 are provided on the top surface of the gland. Four combination screws 12 are used to cooperate with the four waterproof nuts to install two "Ω" - shaped clamps 11 on the top of the gland (each clamp needs to be fixed with two combination screws). The waterproof nuts can prevent water from flowing into the inside of the central control box. The clamp is made of stainless steel and is formed by bending a plate. As Figure 5 shown, the clamp can fix the central control box on the column 31.

[0032] The surface roughness of the groove of the sealing groove is less than 3.2 um. The sealing ring has a circular cross - section and is made of conductive silica gel, which can not only ensure the electromagnetic shielding performance but also ensure the waterproof performance.
