Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cable wiring technology, and in particular to a stress-resistant photovoltaic cable wiring structure. Background Technology

[0002] With environmental awareness growing stronger, the development of new energy sources is booming. Among these, the photovoltaic industry is beginning to reach countless households, with many families and businesses, especially in rural areas, installing solar panels. When installing solar panels, in addition to paying attention to the panels themselves, the cable connections and wiring are also of paramount importance.

[0003] For small-scale photovoltaic (PV) power generation systems, especially those with residential PV panels, while the wiring of PV cables is relatively simple, it is still important to ensure the cables are stable and secure. Therefore, it is best to use cable clamps or cable ties to secure the cables at short intervals.

[0004] However, even when properly secured, photovoltaic cables inevitably experience pulling and dragging during long-term use. In such situations, the photovoltaic cable itself must withstand the stress, which can easily damage the cable. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a stress-resistant photovoltaic cable wiring structure to solve the problem that the wiring of photovoltaic cables in the prior art lacks the ability to resist external stress and is easily damaged.

[0006] To achieve the above objectives, this utility model provides a stress-resistant photovoltaic cable wiring structure, including a base for fixing the photovoltaic cable to a wall or ground, and the wiring structure further includes...

[0007] A fixed ring is fixedly connected to the middle position of the base. A movable tube is slidably connected in the fixed ring for the photovoltaic cable to pass through. Both ends of the movable tube are fixedly connected to protruding edges, which are slidably connected to the base.

[0008] A pressure plate is movably connected inside the movable tube to clamp and fix the photovoltaic cable inside the movable tube. A limiting member is provided between the pressure plate and the movable tube to limit the downward movement range of the pressure plate.

[0009] A buffer spring is fitted onto the movable tube, with its two ends connected to a fixed ring and a convex edge, respectively.

[0010] Furthermore, several sliding pressure strips are fixedly connected to the pressure plate, with the upper end of the sliding pressure strip passing through the side wall of the movable tube and protruding.

[0011] Furthermore, the fixing ring is also provided with several pressure bolts, and each pressure bolt corresponds to a sliding pressure strip. A ball is rolledly connected to the bottom of the pressure bolt, and the ball is rolledly connected to the sliding pressure strip.

[0012] Furthermore, the pressure plate is an arc-shaped plate, and both ends of the movable tube and the pressure plate are provided with arc-shaped chamfers.

[0013] Furthermore, two buffer springs are provided, which are respectively sleeved on the movable tubes on both sides of the fixed ring.

[0014] Furthermore, the base is provided with hexagon socket head cap screws, and the wire clamping bolts are cross bolts.

[0015] Furthermore, the limiting component includes a limiting groove inside the movable tube, a limiting rod is provided in the limiting groove, a circular plate is fixedly connected to the upper end of the limiting rod, and the lower end of the limiting rod is fixedly connected to the upper end of the pressure plate.

[0016] Furthermore, a return spring is provided in the limiting groove, and the two ends of the return spring are respectively connected to the top circular plate of the limiting rod and the movable tube.

[0017] The beneficial effects of this utility model are as follows: 1. First, the photovoltaic cable is fixed in the movable tube, and then the base supporting the movable tube is fixed to the wall or ground, thus achieving the fixed installation of the photovoltaic cable. A clamping plate is set in the movable tube to clamp the photovoltaic cable, ensuring a secure installation.

[0018] 2. The movable tube itself is movable, and a buffer spring is fitted on the movable tube. When the photovoltaic cable is subjected to pulling or dragging, it can also move to a certain extent, avoiding hard pulling. The buffer spring absorbs stress, which greatly relieves the instantaneous stress on the photovoltaic cable and effectively protects the photovoltaic cable.

[0019] 3. The clamping plate in the movable tube is driven to clamp the photovoltaic cable by the external clamping bolts. This not only ensures a very secure clamping but also simplifies the operation. At the same time, the clamping bolts are connected to the sliding pressure strip by the ball bearings at the bottom. Therefore, the clamping bolts play a clamping role but do not affect the movement of the movable tube. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0030] The first aspect of this utility model is as follows: Figure 1 and Figure 2As shown, in order to solve the problem that photovoltaic cables 01 are easily damaged by external stress when subjected to pulling, dragging and other situations during long-term use, a new wiring structure is specially designed to replace the existing wire clamps or wire fasteners to fix photovoltaic cables 01. Without changing the structure of photovoltaic cables 01 themselves, the wiring structure allows photovoltaic cables 01 to effectively resist external stress, making photovoltaic cables 01 less prone to damage.

[0031] Specifically, the main structure consists of a base 101, a fixing ring 102, and a movable tube 103. The base 101 is bolted for fixing to a wall or ground. The fixing ring 102 is fixedly connected to the middle of the base 101, while the movable tube 103 is slidably connected within the fixing ring 102 (the movable tube 103 and the fixing ring 102 can only slide, not rotate relative to each other, to avoid twisting the photovoltaic cable 01). The photovoltaic cable 01 passes through the movable tube 103. Protruding edges 104 are fixedly connected to both ends of the movable tube 103, and these protruding edges 104 are slidably connected to the base 101.

[0032] The key point is that two buffer springs 105 are fitted onto the movable tube 103, respectively fitted onto the movable tube 103 on both sides of the fixed ring 102. The two ends of the buffer springs 105 are connected to the fixed ring 102 and the protruding edge 104, respectively.

[0033] The movable tube 103 itself is movable, and a buffer spring 105 is sleeved on the movable tube 103. When the photovoltaic cable 01 is subjected to pulling or dragging, the photovoltaic cable 01 can also move to a certain extent, avoiding hard pulling. The buffer spring 105 absorbs stress, which greatly relieves the instantaneous stress on the photovoltaic cable 01 and effectively protects the photovoltaic cable 01.

[0034] Preferably, the bolts on the base 101 are socket head cap screws or cross bolts, and preferably socket head cap screws.

[0035] Another aspect of this utility model is, as Figure 2 , Figure 3 and Figure 4 As shown, the inner diameter of the movable tube 103 is larger than the diameter of the photovoltaic cable 01, approximately 2-3 times the diameter of the photovoltaic cable 01. This not only facilitates the installation of the photovoltaic cable 01 but also allows for compatibility with a wider variety of photovoltaic cables 01. Therefore, to secure the photovoltaic cable 01 within the movable tube 103, a clamping plate 106 is installed inside the movable tube 103. The clamping plate 106 clamps and secures the photovoltaic cable 01 within the movable tube 103, and a limiting member 110 is provided between the clamping plate 106 and the movable tube 103 to limit the downward movement of the clamping plate 106.

[0036] The downward clamping of the wire clamping plate 106 is achieved by a number of wire clamping bolts 107 set on the fixed ring 102. A number of sliding pressure strips 108 are also fixedly connected to the wire clamping plate 106. The upper end of the sliding pressure strip 108 passes through the side wall of the movable tube 103 and protrudes. The fixed ring 102 is also provided with a number of wire clamping bolts 107, and each wire clamping bolt 107 corresponds to a sliding pressure strip 108. A ball bearing 109 is rolledly connected to the bottom of the wire clamping bolt 107, and the ball bearing 109 is rolledly connected to the sliding pressure strip 108.

[0037] Therefore, it is only necessary to tighten the pressure bolt 107 downwards. The pressure bolt 107 moves down and presses the sliding pressure strip 108 down. The sliding pressure strip 108 moves down and moves the pressure plate 106 down to clamp the photovoltaic cable 01, thus ensuring a secure installation.

[0038] Preferably, the wire clamping bolt 107 is an internal hex bolt or a cross bolt, and most preferably a cross bolt.

[0039] The purpose of setting the ball bearing 109 is to replace sliding friction with rolling friction, thereby greatly reducing friction. This ensures that although the pressure bolt 107 presses down on the sliding pressure bar 108, it does not obstruct the movement of the sliding pressure bar 108 and the movable tube 103.

[0040] like Figure 4 and Figure 5 As shown, the clamping plate 106 in the movable tube 103 is driven to clamp the photovoltaic cable 01 by the external clamping bolt 107. This not only ensures a very secure clamping, but also makes the operation simpler. At the same time, the clamping bolt 107 is connected to the sliding pressure strip 108 by the bottom ball 109. Therefore, the clamping bolt 107 can play a clamping role but will not affect the movement of the movable tube 103.

[0041] The limiting member 110 is used to limit the downward movement range of the pressure plate 106. The limiting member 110 includes a limiting groove 111 inside the movable tube 103. A limiting rod 112 is provided in the limiting groove 111. A circular plate is fixedly connected to the upper end of the limiting rod 112, which is similar to a thumbtack. The lower end of the limiting rod 112 is fixedly connected to the upper end of the pressure plate 106. A return spring 113 is also provided in the limiting groove 111. The return spring 113 is sleeved on the limiting rod 112. The upper end of the return spring 113 is connected to the top circular plate of the limiting rod 112, and the lower end of the return spring 113 is connected to the movable tube 103 at the lower end of the limiting groove 111.

[0042] The reset spring 113 allows the wire clamping plate 106 to move automatically upward after the wire clamping bolt 107 is loosened.

[0043] Specific embodiment: When installing and wiring the photovoltaic cable 01, first pass the photovoltaic cable 01 through the movable tube 103, and then simply tighten the wire clamping bolt 107 downwards. The wire clamping bolt 107 moves down and presses the sliding pressure strip 108 down. The sliding pressure strip 108 moves down and moves the wire clamping plate 106 down to clamp the photovoltaic cable 01, thus ensuring a secure installation.

[0044] When wiring adjacent photovoltaic cables 01, a certain length of photovoltaic cable 01 should be reserved, and the photovoltaic cable 01 should not be stretched taut.

[0045] During long-term use, when photovoltaic cable 01 is subjected to pulling or dragging, it can also move to a certain extent, avoiding hard pulling. At the same time, the buffer spring 105 absorbs stress, which greatly alleviates the instantaneous stress on photovoltaic cable 01 and effectively protects photovoltaic cable 01.

[0046] When disassembling or loosening the photovoltaic cable 01, simply loosen the pressure bolt 107. After the pressure bolt 107 moves upward, the pressure plate 106 will also move upward automatically under the action of the reset spring 113, making it easy to remove the photovoltaic cable 01.

[0047] In summary, the photovoltaic cable 01 is fixed in the movable tube 103, and the base 101 supporting the movable tube 103 is fixed to the wall or ground, thus achieving the fixed installation of the photovoltaic cable 01. A clamping plate 106 is installed in the movable tube 103 to clamp the photovoltaic cable 01, ensuring a secure installation. The movable tube 103 itself is movable, and a buffer spring 105 is fitted on it. When the photovoltaic cable 01 is subjected to pulling or dragging, it allows the photovoltaic cable 01 to move to a certain extent, avoiding hard pulling. The buffer spring 105 absorbs stress, greatly alleviating the instantaneous stress on the photovoltaic cable 01 and effectively protecting it.
