Description

Technical Field

[0001] This invention relates to the field of photovoltaic power plant construction technology, and in particular to a DC line wiring device for photovoltaic power plants. Background Technology

[0002] The DC cable routing device for a photovoltaic power station refers to the arrangement and connection device for DC line cables, used to connect the DC power lines between photovoltaic modules and inverters. During the laying of photovoltaic optical cables, to protect the cables and prevent damage from exposed surfaces, cable sheaths are fitted over the cables. These cable sheaths are typically connected using pipe joints, allowing the cable sheaths to adapt to changes in cable length.

[0003] In existing technologies, pipe joints have the following problems: 1. The pipe joint size is fixed. A pipe joint of the same size can only be used on a cable conduit of the corresponding size, which cannot meet the requirements of connecting between conduits of different sizes, resulting in low flexibility of use; 2. For pipe joints connecting two sets of cable conduits, there is a lack of measures to fix the optical cable (i.e., it is impossible to fix the optical cable passing through the pipe joint). The optical cable without fixation may move or rub inside the cable conduit, resulting in knots or crosses, leading to unnecessary electrical and fire risks. Based on this, we propose a DC line wiring device for photovoltaic power stations to solve these problems. Summary of the Invention

[0032] Secondly, the present invention is described in detail with reference to the schematic diagrams.

[0033] Example 1

[0034] Reference Figures 1-2 This first embodiment of the invention provides a DC cable routing device for a photovoltaic power station. The device includes a connecting unit 100, comprising a connecting component 101 located between two sets of cable conduits, a connecting component 102 disposed between the connecting components 101, plug-in components 103 symmetrically disposed at both ends of the connecting component 101, adjusting components 104 symmetrically sleeved at both ends of the connecting component 101 and located inside the plug-in components 103, and three sets of fixing components 105 equally distributed around the adjusting components 104, with the three sets of fixing components 105 extending outwards. The adjusting components 104 are threadedly connected to the connecting component 101, the plug-in components 103 are fixedly connected to both sides of the connecting component 101, and the three sets of fixing components 105 can expand outwards and converge inwards around the plug-in components 103.

[0035] During use, the connecting component 101 and the plug-in component 103 are interconnected, so the optical cable can pass through freely. The plug-in component 103 has a conical structure, which can be inserted into cable sleeves of different diameters, thus having a wider range of applications. Furthermore, the connecting unit 100 plugged into the cable sleeve can be further fixed by three sets of fixing components 105 that hug and gather inward, ensuring its connection with the cable sleeve.

[0036] The clamping unit 200 includes a driving component 201 sleeved on the connecting component 102, a driving assembly 202 located on one side of the driving component 201 and sleeved on the communicating component 101, four sets of first clamping assemblies 203 with a rectangular structure disposed within the driving component 201, each set of first clamping assemblies 203 corresponding to one side of the rectangular structure, and second clamping assemblies 204 disposed on the side of each set of first clamping assemblies 203, the number and position of the second clamping assemblies 204 corresponding one-to-one with the first clamping assemblies 203. The driving component 201 is sleeved on the communicating component 101 and can perform circumferential rotation at a fixed position, while the driving assembly 202 is threadedly connected to the communicating component 101.

[0037] During use, the first clamping component 203 and the second clamping component 204 are attached together and are in a parallel state. The first clamping component 203 and the second clamping component 204 are the same size, so their edges are on the same horizontal line. Because they are attached together, they move synchronously. The four sets of rectangular first clamping components 203 are staggered in pairs, that is, every two sets of first clamping components 203 are at the same horizontal height. The staggered arrangement ensures that the four sets of first clamping components 203 will not obstruct each other during movement. Similarly, the second clamping components 204 attached to the sides of each set of first clamping components 203 will not obstruct each other.

[0038] Example 2

[0039] Reference Figures 3-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it can be applied to cable conduits of different sizes, thus providing greater flexibility in use.

[0040] Compared to Embodiment 1, the connecting component 101 further includes a first connecting pipe 101a and a second connecting pipe 101b located on both sides of the connecting component 102. The length of the second connecting pipe 101b is greater than the length of the first connecting pipe 101a, and the driving component 202 is threadedly connected to the second connecting pipe 101b. Two sets of plug-in components 103 are respectively fixedly connected to the outer ends of the first connecting pipe 101a and the second connecting pipe 101b. Threaded grooves are provided on both the first connecting pipe 101a and the second connecting pipe 101b.

[0041] The connecting component 102 includes two sets of connecting pieces 102a symmetrically arranged between the first connecting pipe 101a and the second connecting pipe 101b, four sets of first fixed shafts 102b arranged between the two sets of connecting pieces 102a, and limiting pieces 102c arranged on the outer end of the connecting pieces 102a. The end of the first clamping component 203 is sleeved on the first fixed shaft 102b. The diameter of the connecting piece 102a matches the inner diameter of the driving component 201. The driving component 201 can be sleeved on the connecting piece 102a and can rotate circumferentially. The diameter of the limiting piece 102c is larger than the inner diameter of the first driving ring 201a. Therefore, the two sets of limiting pieces 102c can limit the driving component 201 on the connecting component 102.

[0042] The plug-in component 103 includes a plug-in assembly 103a located at the outer end of the connecting component 101, a partition 103b disposed between the plug-in assembly 103a and the connecting component 101, three sets of storage slots 103c opened on the plug-in assembly 103a, and a limiting slot 103d opened on the partition 103b, wherein the inner ends of the three sets of limiting slots 103d and the three sets of storage slots 103c are correspondingly connected. The limiting slot 103d is a rectangular structure slot. An object that fits into the rectangular structure slot cannot rotate within the limiting slot 103d and can only slide in the vertical direction.

[0043] During use, the plug-in assembly 103a has an overall conical structure. The conical structure makes the thickness of the plug-in assembly 103a gradually increase from the outside to the inside. The plug-in assembly 103a is divided into several segments along its axis, and it can be seen that the diameter of each segment is different. Different diameters can be plugged into cable sleeves of different sizes, making the device more flexible in use and thus able to meet more usage needs.

[0044] The adjusting component 104 includes an adjusting disk 104a sleeved on the connecting component 101, three sets of adjusting grooves 104b opened on the adjusting disk 104a and one end of the fixing component 105 extending into the adjusting grooves 104b, a first threaded surface 104c set on the inner wall of the adjusting disk 104a, and a lever 104d set on the outer edge of the adjusting disk 104a. The adjusting disk 104a is a circular structure in whole, and a threaded connection is formed by the first threaded surface 104c engaging with the thread of the connecting component 101. The outer end of the lever 104d is higher than the outer extension of the adjusting disk 104a, which can be easily turned and improve the friction during contact.

[0045] Furthermore, the adjusting groove 104b has an arc-shaped structure. One end of the arc-shaped structure is close to the connecting component 101, while the other end is far from the first connecting pipe 101a. The fixed shaft 105a is normally located inside the adjusting groove 104b and can slide along the adjusting groove 104b. When the fixed shaft 105a moves along the adjusting groove 104b from the end away from the connecting component 101 to the end closer to the connecting component 101, the fixed component 105 moves gradually towards the connecting component 101. Conversely, it moves gradually away from the connecting component 101.

[0046] The fixing component 105 includes a fixing shaft 105a extending into the adjusting groove 104b, a clamping plate 105b disposed at one end of the fixing shaft 105a and located directly above the storage groove 103c, and a limiting slider 105c disposed between the fixing shaft 105a and the clamping plate 105b. The clamping plate 105b and the storage groove 103c are structurally matched, so the clamping plate 105b can be moved and stored in the storage groove 103c. The limiting slider 105c has a rectangular structure and is located entirely within the limiting groove 103d. The rectangular planes on both sides of the slider abut against the inner side of the limiting groove 103d and are limited by the limiting groove 103d, preventing circumferential rotation.

[0047] During use, after inserting the plug-in component 103a into the cable conduit, the adjusting disc 104a is rotated. The adjusting disc 104a rotates along the axial direction of the connecting component 101. The rotating adjusting disc 104a changes the position of the adjusting groove 104b, thereby pushing the fixed shaft 105a in the adjusting groove 104b to slide. The sliding fixed shaft 105a gradually moves closer to the plug-in component 103. The moving fixed shaft 105a drives the clamping plate 105b to move and finally abuts against the outer wall of the cable conduit. The three sets of fixed components 105 move synchronously and can abut and squeeze the cable conduit from three directions, thereby strengthening the connection between the plug-in component 103 and the cable conduit.

[0048] The remaining structure is the same as that in Example 1.

[0049] Example 3

[0050] Reference Figures 6-10 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the optical cable passing through the inside of the device is clamped and fixed to prevent displacement and friction, thereby ensuring the safety of the optical cable.

[0051] Compared to Embodiment 2, the driving component 201 further includes a first driving ring 201a sleeved on the outside of the connecting piece 102a, a relief groove 201b formed in the first driving ring 201a, four sets of second fixed shafts 201c evenly distributed in the relief groove 201b, and the end of the second clamping component 204 sleeved on the second fixed shafts 201c, and three sets of limiting slide rods 201d distributed around the side of the first driving ring 201a. The limiting slide rods 201d are fixedly connected to the side of the first driving ring 201a. The first driving ring 201a can rotate circumferentially on the connecting component 102 by being limited by the limiting piece 102c.

[0052] The drive assembly 202 includes a second drive ring 202a sleeved on the second connecting pipe 101b, three sets of limiting holes 202b opened on the second drive ring 202a, and a limiting slide rod 201d extending into the limiting holes 202b, and a second threaded surface 202c provided on the inner wall of the second drive ring 202a. The second drive ring 202a is threadedly connected to the second connecting pipe 101b through the second threaded surface 202c. The limiting slide rod 201d passes through the limiting holes 202b, so the two are in a sliding connection relationship. However, the drive component 201 and the drive assembly 202 are mutually limited in the horizontal direction by the limiting slide rod 201d, and the two cannot rotate in a circular direction independently.

[0053] The first clamping assembly 203 includes a first clamping rod 203a located within the drive assembly 202, a first collar 203b disposed at the end of the first clamping rod 203a and sleeved on the first fixed shaft 102b, a first sliding groove 203c formed on the first clamping rod 203a, and a first limiting shaft 203d disposed on one side of the first sliding groove 203c and extending into the second clamping assembly 204. The first clamping assembly 203 is rotatably connected between the two sets of connecting pieces 102a through the first collar 203b and can rotate with the first fixed shaft 102b as the axis.

[0054] The second clamping assembly 204 includes a second clamping rod 204a located on the side of the first clamping rod 203a and parallel to the first clamping rod 203a; a second collar 204b disposed at one end of the second clamping rod 204a and sleeved on the second fixed shaft 201c; a second sliding groove 204c formed on the second clamping rod 204a and extending into the second sliding groove 204c; and a second limiting shaft 204d disposed on the inner side of the second clamping rod 204a and extending into the first sliding groove 203c. The second clamping assembly 204 is slidably connected to the side of the first clamping assembly 203 through the second limiting shaft 204d. The two are limited to horizontal translation and sliding only by the mutual limitation of the second limiting shaft 204d and the first limiting shaft 203d.

[0055] During use, rotating the drive assembly 202 causes the drive component 201 to rotate synchronously. The rotating drive component 201 then drives the second clamping assembly 204 to rotate via the second fixed shaft 201c. Because the second clamping assembly 204 is in contact with and limited by the first clamping assembly 203, the first clamping assembly 203 also moves accordingly. Simultaneously, the end of the first clamping assembly 203 is sleeved on the first fixed shaft 102b. The connecting component 102 as a whole does not rotate with the drive assembly 202. Therefore, the second clamping assembly 204 and the first clamping assembly 203 rotate around the first fixed shaft 102b. The sides of the rotating first clamping assembly 203 and the second clamping assembly 204 gradually move towards the drive component 201c. When the driving component 201 rotates, the distance between the second fixed shaft 201c and the first fixed shaft 102b changes. At this time, the first clamping component 203 and the second clamping component 204 will translate in opposite directions to satisfy the change in the distance between the second fixed shaft 201c and the first fixed shaft 102b. The four sets of first clamping components 203 and the four sets of second clamping components 204 move in the same way, that is, the four sets of first clamping components 203 and the corresponding second clamping components 204 simultaneously converge toward the center of the driving component 201. The first clamping components 203 and the second clamping components 204 converging inward will eventually clamp and fix the optical cable, thereby achieving the purpose of fixing the optical cable passing through the device, thus better ensuring the safety of the optical cable.

[0056] The remaining structure is the same as that in Example 2.
