Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic cable installation, and in particular to a photovoltaic cable wiring device and method. Background Art

[0002] Photovoltaic cable is a cable designed for solar photovoltaic systems. It is used to connect photovoltaic modules, inverters and power grids to achieve the transmission and distribution of solar power. This cable has a specific design and materials to meet the high requirements for safety, durability and efficiency in photovoltaic systems.

[0003] The Chinese publication number is: CN116706824A, which discloses a photovoltaic cable connection point protection device, including a mounting seat, a first bracket, etc. The first bracket is welded in the middle of the top of the mounting seat, and the first bracket is used to support a first connector and a second connector. When people pull the photovoltaic cable, the present invention will cause the first sliding sleeve to move, and under the action of the compression spring, the photovoltaic cable can be buffered and protected. When the first sliding sleeve moves, the gear and the rack cooperate, and the elastic telescopic clamp automatically moves down to reinforce the first connector and the second connector, thereby avoiding damage to the photovoltaic cable.

[0004] Although the above invention utilizes the telescopic clamp to automatically move downward to reinforce the first connector and the second connector, and can protect the cable, it does not take into account that the aging and vibration of the wiring device during long-term use may cause the connection to loosen and affect the transmission. At the same time, during the replacement or maintenance process, the photovoltaic cable will entangle the wires and wrap the outer skin after wiring, which increases the difficulty of maintenance when it needs to be replaced and repaired again later. In addition, some photovoltaic cables need to be pre-buried, and it is necessary to prevent the problem of water seepage in the photovoltaic cables during long-term pre-buried periods on rainy days.

[0019] On the other hand, the present invention also provides a method for using a photovoltaic cable connection device and method, including a photovoltaic cable connection device as described in any one of the above, and the operation steps are as follows:

[0020] S1. First, the inner side of the photovoltaic cable self-adjusting device is inserted into the No. 1 sorting ring, and the inclined oblique blade is pressed against the outer skin of the photovoltaic cable;

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0042] Example 1: Please refer to Figure 1-Figure 8As shown, the present embodiment provides a photovoltaic cable wiring device, comprising a No. 1 wiring tube 1 and a No. 2 wiring tube 2, wherein the No. 1 wiring tube 1 is provided with a No. 1 tidying ring 12 for tidying up the wires at one end of the cable, and the No. 2 wiring tube 2 is provided with a No. 2 tidying ring 22 for tidying up the wires at the other end of the cable, and the outer sides of the No. 1 tidying ring 12 and the No. 2 tidying ring 22 are provided with a stripping assembly 3, and the stripping assembly 3 is provided with a tension assembly 322 for reducing shaking and buffering, and the stripping assembly 3 is provided with an oblique blade 3214 for stripping, and the stripping assembly 3 is provided with an adjusting device 4 for adjusting the tightness of the fixed cable on the side away from the No. 1 wiring tube 1, wherein: the No. 1 wiring tube 1 and the No. 2 wiring tube 2 are rotated, the oblique blade 3214 and the tension assembly 322 are used to complete the stripping of the cable sheath, and the sealing and fixing of the cable are completed by the adjusting device 4.

[0043] like Figure 8 As shown, the inner wall of the middle end of the No. 1 wiring tube 1 is fixedly connected to one end of the No. 1 column 11, the other end of the No. 1 column 11 is fixedly connected to the No. 1 sorting ring 12, a thread groove 13 is provided on the inner wall of one end of the No. 1 wiring tube 1, the inner wall of the No. 2 wiring tube 2 is fixedly connected to one end of the No. 2 column 21, the other end of the No. 2 column 21 is fixedly connected to the No. 2 sorting ring 22, and the outer wall of the No. 2 wiring tube 2 at one end close to the No. 1 wiring tube 1 is fixedly connected to a threaded protrusion 23, wherein: the inner wall diameter of the No. 1 sorting ring 12 is the same as the outer wall diameter of the No. 2 sorting ring 22, and the threaded protrusion 23 fits with the thread groove 13.

[0044] like Figure 4-Figure 7 As shown, the stripping assembly 3 includes a sliding ring 31, the outer wall of the sliding ring 31 is provided with a No. 1 annular groove 311, the outer side of the inner wall of the sliding ring 31 is provided with a slope 312, the inner side of the sliding ring 31 is provided with a No. 1 fixing ring 32, the inner wall of the sliding ring 31 is slidably connected to the outer wall of the No. 1 fixing ring 32, the No. 1 fixing ring 32 is provided with a conical piece 3211 on the inner side of the end away from the No. 1 wiring tube 1, the bottom of the conical piece 3211 is fixedly connected to one end of the No. 1 spring 3212, and the other end of the No. 1 spring 3212 is fixedly connected to a split fixing A fixed ring 3213, the inner side of the split fixed ring 3213 is rotatably connected with an oblique blade 3214, wherein: a stripping assembly 3 and an adjusting device 4 are provided on one side of the No. 1 wiring tube 1 and the No. 2 wiring tube 2, an irregular groove 321 is provided on the outer wall of the No. 1 fixed ring 32, a tension assembly 322 is provided on the inner side of the irregular groove 321, the tension assembly 322 includes a bending lever 3221, the bending part of the bending lever 3221 is rotatably connected to the inner wall of the irregular groove 321, and an elastic ring 3222 is provided at one end of the bending lever 3221.

[0045] like Figure 5As shown, the outer wall of the No. 1 fixing ring 32 is slidably connected with a sealing ring 323, and the sealing ring 323 is provided with a No. 2 annular groove 3231 on the side close to the sliding ring 31, and the width of the No. 2 annular groove 3231 matches the width of the sliding ring 31, and the sealing ring 323 is fixedly connected with a sliding member 324 on the side away from the sliding ring 31, and the sliding member 324 is slidably connected to the outer wall of the No. 1 fixing ring 32, and the inner wall of the No. 2 annular groove 3231 is fixedly connected with a raised ring 3241, and one side of the elastic ring 3222 is in contact with one end of the bent pivot rod 3221, and is fixedly connected to the raised ring 3241 at the upper end on the same side.

[0046] It can be seen from this that when it is necessary to strip the photovoltaic cable, Figure 2-4 As shown, the staff will cut the photovoltaic cable from the direction of the adjustment device 4 to the inside of the No. 1 sorting ring 12 and the No. 2 sorting ring 22, and pass through the inner side of the No. 1 sorting ring 12 and the No. 2 sorting ring 22. When passing through the oblique blade 3214, the oblique blade 3214 will be pushed toward the No. 1 sorting ring 12 and rotated a certain angle toward the direction of the No. 1 sorting ring 12. Then the staff will pinch the sealing ring 44 and pull it outward, so that the photovoltaic cable and the No. 1 fixing ring 32 are pulled outward together, as shown in FIG. Figure 7 As shown, at this time, the sliding ring 31 slides to the right on the No. 1 fixing ring 32. When the sliding ring 31 passes through the tapered member 3211, the tapered member 3211 is blocked by the inclined surface 312, and the tapered member 3211 continuously slides downward and pushes the inclined blade 3214 to retract inward, thereby cutting and peeling off the outer skin of the photovoltaic cable.

[0047] It should be noted that the bevel blade 3214 is distributed in a multi-segment ring shape. When the conical member 3211 pushes the bevel blade 3214 downward, the multi-segment ring-shaped bevel blade 3214 shrinks inward and merges into a complete circle for cutting. Because the operation of the No. 1 wiring tube 1 is the same as that of the No. 2 wiring tube 2, only one of them is introduced in the context.

[0048] Embodiment 2: Different from Embodiment 1, in order to achieve the sealing and fixing of the photovoltaic cable, as Figure 6As shown, the adjusting device 4 includes a No. 2 fixing ring 41, which is fixedly connected to the outer wall of the sliding member 324, and an adjusting component 42 is arranged on the inner side of the sliding member 324. The adjusting component 42 includes a sliding column 421, and the sliding column 421 is fixedly connected to one end of a No. 2 spring 422 by passing through the sliding member 324 and the bottom of the outer wall of the No. 2 fixing ring 41, and the other end of the No. 2 spring 422 is fixedly connected to an adjusting ring 423, and a seesaw 43 is rotatably connected to one side of the sliding column 421, and the middle end of the seesaw 43 is rotatably connected to the inner side of the No. 2 fixing ring 41, and a protruding block 431 is fixedly connected to the bottom of the end of the seesaw 43 away from the sliding column 421, and a sealing ring 44 is slidably connected to the bottom of the No. 2 fixing ring 41, and a V-shaped groove 441 is provided on the top of the sealing ring 44, and the V-shaped groove 441 fits with the protruding block 431.

[0049] It can be seen that when it is necessary to fix and seal the photovoltaic cable after stripping, according to the first embodiment, Figure 7 As shown, after the photovoltaic cable is peeled, the staff pushes the pinched sealing ring 44 inward again. At this time, the sealing ring 44 first slides at the bottom of the second fixing ring 41 toward the direction of the first wiring tube 1, and abuts against the side of the sliding member 324 away from the first wiring tube 1, and at the same time drives the sliding member 324 and the sealing ring 323 to slide in the direction of the sliding ring 31, until the inner wall of the sliding member 324 is in contact with one side of the first fixing ring 32, and pushes the first fixing ring 32 to slide to the right together. At this time, the sliding ring 31 slides relatively to the left on the first fixing ring 32, and passes through the bent tilting rod 3221 , use the inclined surface 312 to gradually press down one end of the bent tilting rod 3221, and pry the other end of the bent tilting rod 3221 close to the elastic ring 3222, and squeeze the elastic ring 3222. Because the upper end of the elastic ring 3222 is fixedly connected to the raised ring 3241 in the sliding member 324, the sliding member 324 will be driven to tighten with the sealing ring 323 to the right. At the same time, the sliding ring 31 also gradually approaches the sealing ring 323 and is fixed to the second annular groove 3231, so that the outer wall of the No. 1 wiring tube 1 is sealed to ensure that the pre-buried photovoltaic cable will not be damaged due to water seepage in rainy days in the underground;

[0050] It should be noted that in the process of pushing the sealing ring 44, the protruding block 431 at the bottom of the seesaw 43 will be separated from the V-shaped groove 441. At this time, the seesaw 43 is pried and drives the sliding column 421 to press down. During the downward pressing process of the sliding column 421, the adjusting ring 423 will be driven to shrink inward (the adjusting ring 423 here is the same as the oblique blade 3214 in Example 1), and clamp the outer wall of the photovoltaic cable to fix it. At the same time, when the protruding block 431 is separated from the V-shaped groove 441, the downward pressure on the sealing ring 44 will also be increased, so that the sealing ring 44 is closer to the outer wall of the photovoltaic cable.

[0051] like Figure 8As shown, finally, the No. 1 wiring tube 1 and the No. 2 wiring tube 2 are rotated and sealed through the threaded groove 13 and the threaded protrusion 23, so that the wires in the No. 1 sorting ring 12 and the No. 2 sorting ring 22 are twisted by the staff, and the No. 1 sorting ring 12 and the No. 2 sorting ring 22 will gradually connect to finally complete the wiring. The whole process is convenient and simple to operate, which can ensure the work efficiency of the staff.

[0052] Embodiment 3: This embodiment provides a method for using a photovoltaic cable connection device, comprising the following method steps:

[0053] S1, firstly, the inner side of the photovoltaic cable self-adjusting device 4 is inserted into the first sorting ring 12, and the inclined oblique blade 3214 is pressed against the outer skin of the photovoltaic cable;

[0054] S2, the staff then squeezes and pulls the sealing ring 44 outward to drive the photovoltaic cable to move, and the oblique blade 3214 rotates in the moving direction of the photovoltaic cable and penetrates into the cable sheath to cut and peel;

[0055] S3, then push the adjustment device 4 toward the direction of the No. 1 wiring tube 1 to fix the No. 2 annular groove 3231 and the sliding ring 31;

[0056] S4. Finally, the staff rotates and tightens the No. 1 wiring tube 1 and the No. 2 wiring tube 2 through the thread groove 13 and the threaded protrusion 23, so that the No. 1 sorting ring 12 overlaps with the No. 2 sorting ring 22, and twists the two ends of the cable by rotating the No. 1 wiring tube 1 or the No. 2 wiring tube 2.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
