Description

Technical Field

[0001] The invention relates to the technical field of cable winding, and in particular to a cable surface cleaning method and a cable winding device with a cleaning function. Background Art

[0002] Cables are an important part of the power transmission system. Most cables are used to connect power stations and substations to achieve efficient power transmission. Both ends of the cable need to be connected to the connectors of the power station and substation, which usually have multiple interfaces. In order to ensure a good electrical connection, the insulation layer at both ends of the cable needs to be pre-stripped to a corresponding length according to the specifications of the connector. There are usually multiple stripped conductors, and each conductor needs to be cleaned to remove the oxide layer and impurities on the surface. After cleaning, each exposed conductor part will be wrapped with an insulation layer, and a connecting piece will be fixed on each conductor end. Subsequently, the conductors are inserted into the corresponding interfaces of the connector to complete the cable connection. Since the cable is exposed to the outdoor environment for a long time, its outer sheath and insulation layer may age and crack, which will affect the electrical performance and service life of the cable, so it is necessary to replace and recycle the old cable regularly. However, the existing cable reel is usually designed for the reeling of new cables, and does not fully consider the special circumstances when recycling old cables. In particular, the end of the old cable has been processed, such as stripping the insulation layer, fixing the connecting piece, and wrapping the insulation layer separately, which makes it difficult to fix the cable end on the reel. During the reeling process, the cable is not reeled neatly, affecting the reeling efficiency and the storage quality of the cable. Summary of the invention

[0003] In order to overcome the shortcomings that the end portion of the old cable is difficult to fix on the reel after processing, and the cable is not reeled neatly during the reeling process, which affects the reeling efficiency and the storage quality of the cable, the present invention provides a cable surface cleaning method and a cable reel with cleaning function.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1-Figure 8 As shown, a cable retractor with a cleaning function comprises a fixing frame 1 and a rotating rod 2; the fixing frame 1 is rotatably connected to the rotating rod 2; a reeling portion 21 is provided on the rotating rod 2; blocking plates 22 are provided on both the front and rear sides of the reeling portion 21; an inverted eight-shaped placement area 2001 is provided on the blocking plate 22;

[0030] It also includes an end fixing system, a slide rail 104, a first electric slider 105, a fixed frame 106, a supporting rod 112 and a limiting plate 113; a first slide groove 1001 is opened on the fixed frame 1; a slide plate 11 is slidably connected to the first slide groove 1001; an end fixing system is provided on the front blocking plate 22 and the slide plate 11; a slide rail 104 is fixedly connected to the fixed frame 1; the first electric slider 105 is slidably connected to the slide rail 104; the first electric slider 105 is installed with a fixed frame 106; a supporting rod 112 is provided on the fixed frame 106; two limiting plates 113 are slidably connected to the supporting rod 112, and each limiting plate 113 is fixedly connected to an electric slider.

[0031] The end fixing system includes a fixed rod 101, a sliding rod 102 and a limiting rod 103; four fixed rods 101 are fixedly connected to the blocking plate 22 and the slide plate 11; six second slide grooves 1002 are opened on the blocking plate 22 and the slide plate 11; each second slide groove 1002 is slidably connected with a sliding rod 102; each sliding rod 102 is provided with a transverse moving slider, which drives the sliding rod 102 to slide on the second slide groove 1002; four groups of limiting rods 103 are fixedly connected to the blocking plate 22 and the slide plate 11; each group of limiting rods 103 has four, and the distribution method of each group of limiting rods 103 is the same as the movement trajectory of the sliding rod 102.

[0032] It also includes a cleaning frame 107, a cleaning plate 109 and a cleaning roller 110; the cleaning frame 107 is arranged on the fixed frame 106; two cleaning plates 109 are fixedly connected to the left and right sides of the cleaning frame 107, and the two cleaning plates 109 on each side are flared from the middle of the cleaning frame 107 to both sides; two cleaning rollers 110 are rotatably connected to the cleaning frame 107; the two cleaning rollers 110 are located between the left cleaning plate 109 and the right cleaning plate 109.

[0033] The cleaning plate 109 is an elastic sheet, which facilitates the cables to enter the cleaning frame 107 .

[0034] It also includes a first driving member 108 ; the first driving member 108 is fixedly connected to the fixed frame 106 ; the first driving member 108 is an electric push rod; and the output end of the first driving member 108 is fixedly connected to the cleaning frame 107 .

[0035] It also includes a cleaning pipe 111 ; the cleaning pipe 111 is fixedly connected to the cleaning frame 107 , and the cleaning pipe 111 is communicated with the inside of the cleaning frame 107 .

[0036] A silicone layer is provided on the limiting sheet 113 to facilitate clamping of the cable.

[0037] In view of the problem that the end part of the old cable has been processed, making it difficult to fix the end part of the cable on the reel, and during the reeling process, the cable is not reeled neatly, affecting the reeling efficiency and the storage quality of the cable, both ends of the cable of the present invention are removed from the connector and scattered in the wild, and then the staff transports the present invention to the wild, takes down the present invention and places it on the ground. First, the staff passes one end of the cable through the fixing frame 106 and passes the cable to the upper side of the supporting rod 112. At this time, the fixing frame 106 is close to the fixing rod 101 on the blocking plate 22, and the cable end is further pulled through the inverted eight-shaped placement area 2001. Then, the cable end is placed on the end fixing system to fix the cable end. The specific operation is as follows: the staff clamps the conductors wrapped with insulation layers at the cable ends between the two fixing rods 101. At this time, the sliding rod 102 is located at the upper end of the second slide groove 1002. On both sides of the fixing rod 101, the cable end conductors are respectively clamped into the two adjacent fixing rods 1 01, the cable is located between the two sliding rods 102. After the cable end is stuck, the moving slider in the second slide groove 1002 is started, and the sliding rod 102 is driven to slide along the second slide groove 1002 by the moving slider. A friction portion is provided on the sliding rod 102. During the sliding process of the sliding rod 102, the friction portion drives the freely hanging cable end conductor to bend along the sliding track of the sliding rod 102. In order to avoid the conductor from being difficult to maintain the bent shape after being bent, a plurality of limiting rods 103 distributed in an arc shape are used to limit the bent conductor to avoid deformation of the conductor after bending. It should be noted that since the conductor will be adjusted in length according to the distance of the cable connector, resulting in different lengths between the conductors, when bending and fixing the conductor, the longer conductor part is difficult to be rolled up. Therefore, each conductor has two sliding rods 102 for sliding and rolling up, and the sliding rod 102 stops when it slides to the connection position between the conductor end and the connector. Therefore, before rolling up the cable, the conductor part of the cable end is fixed.

[0038] Subsequently, the external motor of the present invention is started to drive the rotating rod 2 to rotate counterclockwise from the front to the back, and the winding portion 21 rotates with the rotating rod 2, and the cable is wound as the winding portion 21 rotates. Before winding, the electric slider on the limiting plate 113 is first driven to move toward the cable, driving the limiting plate 113 to clamp and fix the cable. When winding the cable, the first electric slider 105 located on the front side of the present invention follows the winding of the cable by the winding portion 21 and moves along the slide rail 104 toward the rear side of the present invention, driving the cable clamped by the limiting plate 113 to move synchronously toward the rear side of the present invention, and the cable is flatly wound on the winding portion 21. The cable is clamped and fixed by the limiting plate 113, and the cable is driven to move synchronously toward the unwound cable part of the winding portion 21 while winding, thereby avoiding the problem of uneven cable winding due to the cables piling up when winding.

[0039] In addition, since the cable is used for a long time and is piled up on the ground in the field before being reeled in, there are many impurities on the surface of the cable, such as gravel, dust, etc. It is necessary to clean the surface of the cable before reeling in the cable to avoid affecting the reeling of the cable. Before reeling in the cable, the staff holds the cable end and first passes the cable end through the cleaning frame 107 fixed on the fixed frame 106, and then passes through the fixed frame 106. Before the cable end passes through the cleaning frame 107, the sliding rod 102 is a spring. First, the cable end squeezes the cleaning plate 109 and passes between the two cleaning plates 109. At this time, the cleaning plate 109 scrapes and cleans the gravel on the cable surface, and the dust on the cable is brushed off by the bristles on the cleaning roller 110. After the cleaning of the cable end is completed, when the cable is rolled up in the present invention, the cable is cleaned in the same way. During the cable rolling process, in order to prevent the cleaning roller 110 from cleaning impurities on the cable surface and causing the cleaned impurities to fall onto the rolled cable, a cleaning plate 109 is also provided near the fixed frame 106 to prevent impurities from falling onto the rolled cable. At the same time, there will be more impurities brushed off the cable between the two cleaning plates 109 on the lower side. Therefore, before the cleaning plate 109 cleans the cable, an external air pump is connected to the cleaning pipe 111 to start the external air pump. While cleaning the cable, the impurities between the two cleaning plates 109 on the lower side are extracted to avoid affecting the effect of the cleaning roller 110 in cleaning the cable.

[0040] After the present invention has rolled up most of the cables, since both ends of the cables have been processed, it is difficult to fix the end portion of the cables on the winding reel, and since the position of the end of the cables cannot be determined manually, it is difficult to neatly roll up the end portion of the cables. Therefore, when the starting end of the conductor at the end of the cable is located in front of the cleaning frame 107, the rotation of the rotating rod 2 is stopped, and then the output end of the first driving member 108 is driven to drive the cleaning frame 107 to move forward, pass through the cable conductor portion located in front of it, and clean the conductor portion. Then, the output end of the first driving member 108 drives the cleaning frame 107 back to its original position. At this time, the staff pulls all the conductors to prevent the conductors from affecting the cleaning frame 107 from returning to its original position. Then, according to the position of the conductor driven by the first electric slider 105, the slide plate 11 is manually slid to the position of the conductor, and the conductor is fixed to the end fixing system on the slide plate 11, thereby completing the winding and cleaning of the cable.

[0041] Example 2

[0042] On the basis of Example 1, Figure 8 and Fig. 9 As shown, it also includes a fixed plate 201 and a pulley 202; two fixed plates 201 are fixedly connected to the fixed frame 106; the two fixed plates 201 are connected to the pulley 202 for rotation together.

[0043] The surface of the pulley 202 is coated with a dry lubricant to reduce the friction between the cable and the pulley 202 .

[0044] A cable surface cleaning method comprises the following steps:

[0045] Step 1: The staff holds one end of the cable and aligns it with the cleaning frame 107, preparing to let the cable pass through the cleaning frame 107;

[0046] Step 2: During the whole process of the cable passing through the cleaning frame 107, the cable first contacts the cleaning plate 109, and the cleaning plate 109 scrapes away the impurities and gravel on the surface. After passing through the cleaning plate 109, the cable contacts the cleaning roller 110, and the dust on the cable surface is brushed away by the cleaning roller 110. At the same time, the cleaning pipe 111 sucks air from the cleaning roller 110 and the cleaning frame 107 to absorb the dust and impurities brushed away;

[0047] Step 3: Fix the end portion passing through the cleaning frame 107, then control the rotating rod 2 to rotate, and the reeling portion 21 reels the cable. During the reeling process, the cable continuously passes through the cleaning frame 107, and the cleaning plate 109 and the cleaning roller 110 clean the surface of the cable;

[0048] Step 4: The first driving member 108 drives the cleaning frame 107 to move rightward, passes through the end of the cable, and cleans the end of the cable.

[0049] During the reeling process of the high-voltage cable, since the cable is thick and long, it is easy to twist when dragged on the ground, causing the internal conductor to break or crack. In order to reduce this twisting and stress concentration, we set a pulley 202 before the cable enters the cleaning frame 107. Before the cable enters the cleaning frame 107, the cable first passes through the pulley 202. The pulley 202 provides a smooth surface, which reduces the friction between the cable and the supporting surface. The reduction in friction means that the cable is subjected to less resistance when moving, thereby reducing the stress caused by friction and making the cable easier to move. At the same time, the pulley 202 can disperse the stress on the cable by providing a larger contact area. In this way, the stress on the cable is no longer concentrated on a certain point, but is distributed on the contact surface of the entire pulley 202 to reduce stress concentration, provide continuous support, reduce shock and vibration, reduce the twisting of the cable when it is reeled, and reduce the possibility of the internal conductor of the cable breaking. When recycling reusable cables, the integrity and performance of the cable are ensured.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
