Description

Technical Field

[0001] This utility model relates to a positioning and fixing device for photovoltaic cables, belonging to the field of photovoltaic cable fixing technology. Background Technology

[0002] The characteristics of photovoltaic cables are determined by their specialized insulation and sheath materials, known as cross-linked polyethylene (PE). Irradiation by an accelerator alters the molecular structure of the cable material, thus improving its various properties. Regarding mechanical load resistance, during installation and maintenance, cables may be laid along the sharp edges of roof structures, and must withstand pressure, bending, tension, cross-tension loads, and strong impacts. If the cable sheath strength is insufficient, the cable insulation will be severely damaged, affecting the overall lifespan of the cable or leading to problems such as short circuits, fires, and personal injury hazards.

[0003] In the prior art, patent publication number CN 219937834U, entitled "A Cable Laying and Fixing Device for Photovoltaic Cables," includes a first semi-ring block and a second semi-ring block disposed on one side of the first semi-ring block. A locking strip is fixedly connected to one side of the second semi-ring block. A locking groove adapted to the locking strip is opened on one side of the first semi-ring block. An arc-shaped sliding groove is opened on the front of the first semi-ring block. An arc-shaped baffle is slidably connected to the inner surface of the arc-shaped sliding groove through a slider. A cable laying tube is fixedly connected to the outer surface of the second semi-ring block. A cable laying rod adapted to the cable laying tube is fixedly connected to the outer surface of the first semi-ring block. The first and second semi-ring blocks are fitted onto the outer surface of the photovoltaic cable. The cable laying tube and cable laying rod facilitate the laying and fixing of the photovoltaic cable, while ensuring that the distance between the cables is the same and the laying is aesthetically pleasing. Its beneficial effects are that by fitting the first and second half-ring clips onto the outer surface of the photovoltaic cable, and by setting up the cable tray and cable rod, the photovoltaic cable can be easily fixed, while ensuring that the distance between the cables is the same and the cable arrangement is aesthetically pleasing; by setting up the first spring rod, the stability of the arc baffle is increased, thereby ensuring the stability of the second half-ring clip and preventing the second half-ring clip from detaching from the first half-ring clip, thus ensuring the stability of the cable arrangement.

[0004] However, in the existing technology, the fixing structure for fixing photovoltaic cables is relatively complex, and bolt installation is usually used. Many fixing devices are troublesome to disassemble and reassemble when replacing photovoltaic cables later, which not only increases the installation difficulty, but also makes daily maintenance difficult. Therefore, this utility model provides a simplified fixing structure that facilitates cable installation and subsequent maintenance. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology and overcome the shortcomings mentioned in the background technology by designing a position fixing device for photovoltaic cables.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] Preferably, the fixing component includes a positioning rod and a fixing cylinder. Both the positioning rod and the fixing cylinder are disposed inside the movable slot opened in the fixing block. The positioning rod is fixed to the inside of the movable slot, and the fixing cylinder passes through the through hole and slides in the movable slot via a sliding plate.

[0009] Preferably, a spring is fixedly sleeved on the outer ring of the positioning rod, one end of the spring is fixed to the inner side of the movable slot, and the other end of the spring is fixed to the inner side wall of the fixed cylinder.

[0010] Preferably, a connecting rod is fixedly connected to the top of the fixed cylinder, the connecting rod moves within the through groove, and a snap-fit ​​block is fixedly connected to the top of the connecting rod, the snap-fit ​​block engaging with the snap-fit ​​groove.

[0011] Preferably, the cover plate has multiple observation slots that extend through the cover plate, and a handle is provided at the end of the cover plate away from the rotating shaft, and the handle is fixedly connected to the cover plate.

[0012] Preferably, multiple anti-slip strips are fixedly provided on the inner side of both the fixing block and the cover plate, wherein the multiple anti-slip strips provided on the cover plate are respectively located on both sides of the observation slot.

[0013] Preferably, mounting holes are provided at all four corners of the mounting base.

[0014] The beneficial effects achieved by this utility model are:

[0015] By using a fixing component in conjunction with a snap-fit ​​slot, the main body can be fixed in position when the fixing block and cover plate engage with the snap-fit ​​block through the snap-fit ​​slot.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1-3 As shown, the present invention proposes a positioning device for photovoltaic cables, including a mounting base 1, a fixing block 2 fixedly connected to the top of the mounting base 1, a cover plate 3 provided on the fixing block 2, a movable slot 4 opened on the fixing block 2, a snap-fit ​​groove 5 opened at the bottom of one end of the cover plate 3, a fixing component 6 used in conjunction with the snap-fit ​​groove 5 provided in the movable slot 4, the upper end of the fixing block 2 being rotatably connected to the cover plate 3 through a rotating shaft 7, and a through slot and a through hole opened on the top and one side of the movable slot 4, respectively.

[0023] In this embodiment, a fixing block 2 is fixedly connected to the top of the mounting base 1, and a cover plate 3 is provided on the fixing block 2. The position of the main body can be fixed by the overlap of the fixing block 2 and the cover plate 3, which is convenient. When the cable body needs to be replaced or disassembled for maintenance, it can be easily disassembled by separating the fixing component 6 from the snap-fit ​​groove 5, avoiding direct operation of the cable and reducing potential damage to the photovoltaic cable during maintenance. In the movable groove 4, the separation and engagement of the fixing component 6 can ensure that the cable body remains stable during disassembly and assembly. The upper end of the fixing block 2 is rotatably connected to the cover plate 3 through the rotating shaft 7, so that the rotating shaft 7 can flexibly drive the cover plate 3 to rotate to the required angle, making it easier for the operator to access and handle the photovoltaic cable.

[0024] Example 2

[0025] like Figure 1-3 As shown, the present invention proposes a positioning device for photovoltaic cables. Compared with Embodiment 1, this embodiment further includes a fixing component 6, comprising a positioning rod 61 and a fixing cylinder 62. Both the positioning rod 61 and the fixing cylinder 62 are disposed inside the movable slot 4 opened in the fixing block 2. The positioning rod 61 is fixed to the inner side of the movable slot 4. The fixing cylinder 62 passes through a through hole and slides within the movable slot 4 via a sliding plate 63. A spring 64 is fixedly sleeved on the outer ring of the positioning rod 61. One end of the spring 64 is fixed to the inner side of the movable slot 4, and the other end of the spring 64 is fixed to the inner wall of the fixing cylinder 62. A connecting rod 65 is fixedly connected to the top of the column 62. The connecting rod 65 moves within the through groove. A snap block 66 is fixedly connected to the top of the connecting rod 65. The snap block 66 engages with the snap groove 5. Multiple observation slots 31 are provided on the cover plate 3. The observation slots 31 pass through the cover plate 3. A handle 8 is provided at the end of the cover plate 3 away from the rotating shaft 7. The handle 8 is fixedly connected to the cover plate 3. Multiple anti-slip strips 9 are fixedly provided on the inner side of the fixing block 2 and the cover plate 3. The multiple anti-slip strips 9 provided on the cover plate 3 are located on both sides of the observation slots 31. Mounting holes 01 are provided through the four corners of the mounting base 1.

[0026] In this embodiment, a spring 64 is fixedly sleeved on the outer ring of the positioning rod 61. One end of the spring 64 is fixed to the inner side of the movable slot 4, and the other end of the spring 64 is fixed to the inner side wall of the fixed cylinder 62. The spring can push the fixed cylinder 62 back to its initial position after it is pressed, and the sliding plate 63 slides in the movable slot 4, so that the fixed cylinder 62 will not tilt when pressed, thus improving the stability of the fixing component 6. A latching block 66 is fixedly connected to the top of the connecting rod 65. The latching block 66 engages with the latching slot 5, and the connecting rod 65 can move freely in the through slot, thereby realizing the latching block 66. The device features flexible engagement and disengagement with the latching slot 5. Multiple anti-slip strips 9 are fixedly installed on the inner sides of both the fixing block 2 and the cover plate 3. These anti-slip strips increase friction with the cable and maintain the stability of the photovoltaic cable during operation, preventing slippage or accidental movement. Multiple observation slots 31 are provided on the cover plate 3, allowing observation of the photovoltaic cable's condition between the fixing block 2 and the cover plate 3, and also facilitating heat dissipation. Mounting holes 01 are provided at the four corners of the mounting base 1 for easy installation and improved practicality.

[0027] Working principle: In use, by pressing the fixed cylinder 62, since the fixed cylinder 62 is fixedly connected to the connecting rod 65, and the upper end of the connecting rod 65 is fixedly connected to the latching block 66, the latching block 66 can be driven to move inward. Since the inner wall of 11 is fixedly connected to the spring 64, the spring 64 can make the fixed cylinder 62 spring back to the initial position after being pressed. The fixed cylinder 62 is fixedly connected to the sliding plate 63, and the sliding plate 63 slides in the movable slot 4, so that the fixed cylinder 62 will not be tilted when pressed. Pull the handle 8 to pull the cover plate 3 down. Since the bottom of one end of the cover plate 3 is provided with a latching groove 5, when one end of the cover plate 3 coincides with one end of the fixed block 2, the latching block 66 is just in the latching groove 5 opened in the cover plate 3. Release the fixed cylinder 62, the spring 64 springs back, and drives the latching block 66 to reset. The latching block 66 and the latching groove 5 cooperate to fix the main body well.

[0028] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
