[0026] like Figure 1 , Fig. 9 As shown in FIG. 1 , they are the structural front views of the carbon strips in the two self-wetting carbon slide plates provided by the present invention, such as Figure 2-Figure 6 As shown, it is a top view of the two structural carbon bars of the utility model when grooves of different shapes are opened, such as Figure 7 , Figure 8As shown in the figure, it is a partial cross-sectional view of the grooves on the carbon strip of the utility model and a partial cross-sectional view when the grooves are filled with a carbon film layer. It can be seen from the figures that the self-wetting carbon slide board of the utility model includes: a carbon strip 1 of the carbon slide board; a groove 2 formed on the carbon strip; a carbon film layer 3 filled in the groove of the carbon strip for forming a lubricating film on the surface of the carbon strip. In addition, it also includes a bracket for fixing the carbon strip (not shown in the figure).

[0027] The carbon slide plate can be a curved carbon slide plate, and correspondingly, the bracket is a bracket with a curve, and the carbon strip is also a curved carbon strip. Alternatively, the carbon slide plate can be a straight carbon slide plate without a curve, and correspondingly, the bracket is a bracket without a curve, and the carbon strip is also a straight carbon strip without a curve.

[0028] Among them, the groove of the carbon strip is used to fill the carbon film material that can form a lubricating film on the surface of the carbon strip. The groove is set in the use range section of the carbon slide plate, that is, the groove is set in the corresponding use range section of the carbon strip, and the use range is determined according to actual conditions.

[0029] The grooves may include at least one row of grooves disposed on the surface of the carbon strip, such as a row (e.g. Figure 4 , Figure 6 As shown), two rows (as Figure 2 , Figure 5 As shown), three rows (as Figure 3 No matter how many rows of grooves are arranged, each row of grooves includes a plurality of grooves arranged at intervals along the length extension direction of the carbon strip. If two or more rows of grooves are arranged, the plurality of rows of grooves are arranged at intervals along the width direction of the carbon strip.

[0030] When two or more rows of grooves are arranged on the surface of the carbon strip, the grooves in two adjacent rows of grooves on the surface of the carbon strip are arranged in an up-down staggered manner (e.g. Figure 2 , Figure 3 , Figure 5 Regardless of how many rows of grooves are arranged on the surface of the carbon strip, each groove in each row of grooves can be a linear groove (such as Figure 2 , Figure 3 , Figure 4 As shown), it can also be a hook-shaped groove (as shown Figure 5 As shown), it can also be an eight-shaped groove that forms an eight-shaped groove with adjacent grooves (as shown Figure 6 Of course, the grooves may also be of other shapes.

[0031] During design, the groove can be a horizontal groove extending along the length direction of the carbon strip (e.g. Figure 2 , Figure 3 As shown), it can also be an inclined groove having an angle greater than 0 degrees with the longitudinal extension direction of the carbon strip (as shown Figure 4 The groove may be a groove with constant size in the length or width direction, such as Figure 2 The rectangular groove in the upper row, Figure 3 The rectangular grooves in the bottom row may also be grooves of varying sizes, such as Figure 2 The middle and lower row of grooves, Figure 3 The two rows of grooves in the middle and upper parts are rectangular in the middle and arc-shaped on both sides. Figure 4 , Figure 6 A groove that is narrow at one end and gradually widens at the other end.

[0032] It should be noted that no matter what kind of grooves are set, the number, shape and size of the grooves must ensure that the carbon strip meets various requirements when the carbon slide plate is used, such as strength requirements.

[0033] The carbon film layer is a lubricating film layer made of water-absorbing material, water, graphite, lubricant and curing agent. The water-absorbing material is water-absorbing resin, and the curing agent is epoxy resin or phenolic resin.

[0034] During production, the first step is to open grooves on the existing pure carbon strip or metal-impregnated carbon strip according to the diagram for use (the groove style and size can be determined according to actual conditions).

[0035] In the second step, the water-absorbing material and water are mixed to form a water-containing material, wherein the weight ratio of the water-absorbing material to water is 1:(5-30).

[0036] The third step is to mix the water-containing material, graphite, lubricant and curing agent.

[0037] When mixing, the aqueous material, graphite and lubricant are first mixed. The proportions of each component in the total weight (total weight refers to the weight of the aqueous material, graphite, lubricant and curing agent) are as follows: 10%-65% of the aqueous material, 5%-55% of the graphite and 0.5%-5% of the lubricant.

[0038] After the above materials are mixed evenly, a curing agent (ie, epoxy resin or phenolic resin) is added to the mixture, and the added epoxy resin or phenolic resin accounts for 10%-40% of the total weight of the above materials. The mixture and the curing agent are stirred evenly to form a self-wetting material.

[0039] The fourth step is to fill the self-wetting material into the groove of the above-mentioned carbon strip and perform heat treatment. During the heat treatment, the carbon strip filled with the self-wetting material can be placed at room temperature, which refers to a temperature between 10-35 degrees, and placed at room temperature for 12-24 hours. In addition, the carbon strip filled with the self-wetting material can also be placed in a bellows for heating, the heating temperature is about 100 degrees, and the heating time is 2 hours. After the heat treatment, the self-wetting material filled in the groove of the carbon strip will solidify to form a carbon film layer.

[0040] The fifth step is to process the carbon strips with carbon film layer after heat treatment, and bond and cure them with the bracket after the size meets the requirements to form a carbon slide plate. The carbon slide plate is then processed, assembled with accessories, tested, packaged and stored.

[0041] In addition, a carbon film layer made of other materials that facilitates the formation of a carbon film may also be used.

[0042] When using the carbon slide board of the utility model, the carbon film layer filled in the groove contains water and lubricant, and a lubricating film will be formed on the surface of the carbon strip in a dry climate or dry environment, so that the carbon slide board has the functions of self-wetting and self-lubrication, thereby reducing the friction coefficient when the carbon slide board contacts the network cable, improving the contact interface, reducing the wear of the carbon slide board, and increasing the service life of the carbon slide board.

[0043] Although the present invention has been described in detail above, the present invention is not limited thereto. Those skilled in the art may make modifications based on the principles of the present invention. Therefore, all modifications made based on the principles of the present invention should be understood to fall within the protection scope of the present invention.
