DETAILED DESCRIPTION

[0043] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0044] Example 1

[0045] This embodiment provides a preferred implementation scheme. Figures 1 to 11 As shown, a waterproof and dustproof bus duct comprises two bus cover plates 1 with H-shaped cross sections and two bus side plates 2 with C-shaped cross sections, the two bus cover plates 1 are arranged in parallel, the two bus side plates 2 are arranged in parallel between the two bus cover plates 1 and are perpendicular to the two bus cover plates 1, and the two bus cover plates 1 are assembled with the two bus side plates 2 to form an assembly line for accommodating a busbar.

[0046] This embodiment also includes four square cross-section cast aluminum heads 3, two joint dust and water retaining plates 4, four joint side plates 5, copper bars 6 with polyester sleeves on the outer surface, joint covers 7 and connectors 8.

[0047] The cast aluminum seal 3 is arranged at the ends of the busbar cover 1, and the two cast aluminum seals 3 on one busbar cover 1 are arranged perpendicular to the installation direction of the busbar cover 1. The two end covers of the assembly line are provided with the joint dustproof and waterproof plate 4, which is composed of two rectangular aluminum plates, the middle part of one long side of the aluminum plate is concave inward, and the aluminum plate is provided with two second fixing holes 16 (such as Fig.11 As shown in the figure, only one of the aluminum plates is shown), the two recessed parts of the aluminum plates are opposite to each other and can be combined into a joint dustproof and water-retaining plate 4 with an area consistent with the area of ​​the assembly line port. The recessed parts of the two aluminum plates form a channel for the copper bar 6 to pass through. The joint dustproof and water-retaining plate 4 is installed on the side away from the assembly line with two joint side plates 5. The joint side plates 5 are L-shaped, with an inward recessed part in the middle of the shorter side, and two first fixing holes 15 are opened on the shorter side (such as Fig.10 As shown), the shorter side of the joint side plate is fixed on the joint dust and water baffle plate 4, the two joint side plates 5 are arranged opposite to each other and their installation direction is consistent with the installation direction of the busbar side plate 2; the copper busbar 6 is arranged in the assembly line and extends to between the two joint side plates 5 arranged at the two ends of the assembly line.

[0048] The connector 8 is installed between the connection points of the two groups of bus ducts, the joint cover plate 7 is axially covered above the bus cover plates 1 of the two groups of bus ducts, and the two ends of the joint cover plate 7 are respectively fixedly connected to one of the cast aluminum head 3 on one of the bus cover plates 1. The fixed connection is provided with the first fixing hole 15, which extends from the two ends of the joint cover plate 7 to the cast aluminum head 3, and cooperates with the fixing bolts 17 to fix the joint cover plate 7 and the cast aluminum head 3.

[0049] In this embodiment, the internal structure of the joint dustproof and water-proof plate 4 is provided with the dustproof plate 9, the waterproof layer 10, the sponge layer 11 and the rubber layer 12 in sequence from the external environment to the assembly line. The side of the dustproof plate 9 facing the external environment ensures that dust will not enter from the end of the assembly line; the interior of the waterproof layer 10 is filled with polyurethane coating, which has a waterproof function to ensure that water droplets will not invade the interior of the assembly line, and plays a role in protecting the normal operation of the busbar; the interior of the sponge layer 11 is filled with sponge, so that a small amount of water droplets are adsorbed on the sponge to ensure that water droplets will not invade the interior of the assembly line, which can achieve the function of secondary waterproofing and make the busbar in the assembly line less likely to short-circuit or be damaged; the side of the rubber layer 12 close to the port of the assembly line is a rough surface, which can increase the friction between the joint dustproof and water-proof plate 4 and the contact surface of the assembly line, so that the dustproof and water-proof plate 4 is not easy to move and is more stable.

[0050] In this embodiment, the joint cover plate 7 is provided with a plurality of grooves 13, and the plurality of grooves 13 are arranged in a spiral shape at an inclined and equidistant manner. The arrangement of the grooves 13 allows the accumulated liquid to be discharged from the plurality of grooves 13 on the joint cover plate 7, and since the grooves 13 are arranged in an inclined manner, the liquid can flow easily when the bus duct is arranged vertically or horizontally, and the liquid will not accumulate.

[0051] This embodiment also includes a plurality of drainage holes 14, which are opened on the busbar cover plate 1 near the cast aluminum head 3. The drainage holes 14 have two functions. One is that when the busbar duct is installed horizontally, the accumulated water in the busbar duct can be poured out by pouring; the other is that when the busbar is a four-wire system, the drainage holes 14 can be equipped with a grounding copper braid and used as grounding holes.

[0052] In this embodiment, several of the first fixing holes 15 and several of the second fixing holes 16 are fixed in cooperation with the fixing bolts 17, and the number of the fixing bolts 17 is the sum of the number of the first fixing holes 15 and the number of the second fixing holes 16. This embodiment also includes a foam strip, which is pasted and riveted between the busbar cover plate 1 and the busbar side plate 2. Waterproof, high-viscosity, high-temperature resistant glue is applied to the ports at both ends of the assembly line, the contact points between the connector 8 and the two groups of bus ducts, and the edges of the overlap between the busbar cover plate 1 and the busbar side plate 2, thereby further improving the waterproof ability of the device.

[0053] This embodiment also provides a method for installing a waterproof and dustproof bus duct, and the specific steps are as follows:

[0054] S1: Cut the busbar cover plate 1, the busbar side plate 2 and the copper busbar 6, and remove burrs from the edges and corners of the busbar cover plate 1, the busbar side plate 2 and the copper busbar 6 and grind them smooth;

[0055] S2: performing plastic spraying on the surfaces of the busbar cover plate 1 and the busbar side plate 2 and performing tin plating or silver plating on the outer surface of the copper busbar 6;

[0056] S3: When assembling the busbar cover plate 1, the busbar side plate 2 and the copper bar 6, firstly wrap the copper bar 6 with a polyester sleeve, and then assemble the copper bar 6, the busbar side plate 2 and the busbar cover plate 1 in sequence;

[0057] S4: affix a foam strip between the busbar cover plate 1 and the busbar side plate 2, and then rivet them together, with the riveting interval being 150 mm.

[0058] S5: After the assembly is completed, the cast aluminum head 3 is installed on the busbar cover plate 1, ensuring that the cast aluminum head 3 and the first fixing hole 15 on the busbar cover plate 1 correspond to each other, and then the fixing bolts 17 are screwed on to fix them;

[0059] S6: Install the joint dustproof and water-proof plate 4 and the joint side plate 5 at the end of the assembly line in sequence, ensure that the second fixing holes 16 on the joint dustproof and water-proof plate 4 and the joint side plate 5 correspond to each other, and then fix the joint dustproof and water-proof plate 4 and the joint side plate 5 on the assembly line by the fixing bolts 17;

[0060] S7: Apply waterproof, high-viscosity, high-temperature resistant glue to the ports at both ends of the assembly line;

[0061] S8: assembling multiple groups of the bus ducts, installing the connector 8 at the connection between two adjacent groups of the bus ducts, and then axially covering the joint cover plate 7 outside the two groups of the bus ducts;

[0062] S9: Apply waterproof, highly viscous, and high-temperature resistant glue to the edges of the places where the connector 8 contacts the two groups of bus ducts and where the bus cover plate 1 overlaps the bus side plate 2.

[0063] In this embodiment, after the copper busbar 6, the busbar side plate 2, the busbar cover plate 1, and the cast aluminum head 3 are assembled, if the joint dustproof and water-proof plate 4 is not installed, once water seeps into the bus duct in the shaft, the water will seep into the joint connector 11 along the shaft direction, causing the joint to burn. If the joint dustproof and water-proof plate 3 is installed, and a high-viscosity high-temperature resistant glue is applied to the joints of the two bus ducts and the riveted joints of the busbar cover plate 1 and the busbar side plate 2, if water seeps, the water will flow from the joint dustproof and water-proof plate 4 to the outside of the bus duct, without affecting the normal operation of the busbar, thus playing a role of dustproof and waterproof. The joint dust and water retaining plate 4 described in this embodiment includes the dustproof plate 9, the waterproof layer 10, the sponge layer 11 and the rubber layer 12. The dustproof plate 9 plays a certain dustproof role, the waterproof layer 10 plays a certain waterproof role, the sponge layer 11 plays a secondary waterproof role, and one side of the rubber layer 12 is a rough surface, which increases the contact friction and makes the device less likely to move and more stable. Waterproof, highly sticky and high-temperature resistant glue is applied to each joint of the device to make the waterproof effect better.
