Description

Technical Field

[0001] This invention relates to the field of photovoltaic modules, and in particular to a concealed storage structure for photovoltaic cables. Background Technology

[0002] The main function of photovoltaic (PV) modules is to directly convert solar energy into electrical energy, providing clean energy for various electrical devices. Currently, PV modules are widely used in large-scale ground-mounted power plants, distributed rooftop systems, and off-grid power supply scenarios, effectively alleviating the current situation of resource scarcity.

[0003] Since photovoltaic modules are mostly installed in open-air environments such as rooftops, their associated cable components are exposed to wind and sun for extended periods, as well as rain and snow, which can lead to insulation aging, cracking, or mechanical damage over time. In addition, exposed cables lack neatness and aesthetics in terms of wiring layout and are easily damaged by external forces (such as animal bites or human trampling) or accidental pulling, which may cause short circuits and leakage. Therefore, photovoltaic cables need to be stored and protected.

[0004] Existing technologies mostly use external casings to protect photovoltaic cables, but between the various casing sections, a section of cable will still be exposed, making it susceptible to corrosion from wind and sun, which can eventually damage the entire circuit system. In addition, existing structures for protecting the wiring terminals are mostly fixed installations, which are inconvenient for workers to connect or repair. Therefore, we propose a concealed storage structure for photovoltaic cables. Summary of the Invention

[0005] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a concealed storage structure for photovoltaic cables. Utilizing a hollow support structure for the photovoltaic panel, this structure not only provides installation support but also allows for the sequential downward routing of photovoltaic cables through interconnected channel structures, ensuring that each cable segment is concealed and effectively protecting the photovoltaic cables. Furthermore, it features an easily accessible movable cover, facilitating wiring and maintenance by workers. Under the action of a tension spring, the cover automatically closes at the interface after the worker releases their grip, effectively protecting the wiring terminals. This effectively solves the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concealed storage structure for photovoltaic cables, comprising an inclined beam, a crossbeam, inclined support rods, mounting brackets, and bolt fasteners. The inclined beam has an equilateral triangular cross-section with one apex pointing downwards. Two mounting brackets are symmetrically arranged at the bottom of the inclined beam, both of which are Ω-shaped structures, and both ends are fastened with a set of bolt fasteners. The mounting brackets are clamped and fixed to the outside of a precast column-shaped pile. An inclined support rod is fixedly connected to the middle position of the arched outer part of each of the two mounting brackets. The inclined support rod on the rear side is longer than the inclined support rod on the front side. The upper ends of the two inclined support rods are fixedly connected to the lower sides of the front and rear ends of the inclined beam, respectively. A crossbeam is intersectingly arranged at the middle of the upper side of the inclined beam.

[0007] The horizontal beams support the photovoltaic panels, while the diagonal beams are used for the installation and support of the horizontal beams. The diagonal beams, horizontal beams, and diagonal supports constitute the main support frame. Two mounting brackets are arranged in a ring and are fastened to the outside of the precast column piles with bolts, thereby realizing the installation and fixation between the frame structure and the external piles. The inner sides of the diagonal beams, horizontal beams, diagonal supports, and mounting brackets are all provided with channels for storing photovoltaic cables, and the channels are interconnected, which can conceal and lay the photovoltaic cables. The intersecting areas of the channels inside the diagonal beams and horizontal beams can provide wiring locations for the photovoltaic cables.

[0008] Furthermore, it also includes threaded holes, snap-fit ​​interfaces, and hexagonal socket head cap screws. An isosceles trapezoidal snap-fit ​​interface is provided on the lower side of the middle portion of the crossbeam. The crossbeam is snapped into the inclined beam via the snap-fit ​​interface on the lower side. Two rows of threaded holes are provided along the left and right edges of the upper end face of the inclined beam. Four countersunk holes are provided in the middle of the crossbeam in a rectangular diagonal arrangement. The four countersunk holes can correspond to any set of threaded holes in a rectangular diagonal arrangement. Hexagonal socket head cap screws are installed inside the countersunk holes, and the axial part of the hexagonal socket head cap screws are threaded into the inside of the threaded holes. The crossbeam is fixedly connected to the inclined beam via the hexagonal socket head cap screws. The crossbeam is snapped into the inclined beam via the snap-fit ​​interface, and the hexagonal socket head cap screws are tightened into the threaded holes, thus achieving a fixed connection between the crossbeam and the inclined beam based on the snap-fit ​​connection. The threaded holes arrayed along the edges of the inclined beam can provide additional installation positions for the crossbeams, thereby allowing the number of crossbeams to be increased as needed.

[0009] Furthermore, it also includes square through holes, bolt through holes, and detachable blocks. Three detachable blocks are equidistantly arranged laterally on the upper side end face of the crossbeam. The detachable blocks are fixedly connected to the crossbeam by short blocks with narrow sides. Bolt through holes are also provided inside the upper side of the crossbeam, which are staggered with the detachable blocks. The photovoltaic panel is fixed to the crossbeam by bolts passing through the lower side of the crossbeam. A square through hole is provided in the middle of the upper end of the crossbeam, corresponding to the position of the middle detachable block. The detachable blocks are removed with pliers. The main cable on the back of the photovoltaic panel passes through the through hole formed after the middle detachable block is removed and extends into the square through hole. By cutting the connecting short blocks on all four sides of the removable stop block on the middle side with pliers, the removable stop block can be removed from the crossbeam, exposing the square through hole. This allows the main cable on the back of the photovoltaic panel to be directly aligned and inserted into the square through hole after the panel is attached and installed, achieving concealment. By removing the removable stop blocks on the edge side, holes can be provided for other cables on the back of the photovoltaic panel to pass through into the crossbeam.

[0010] Furthermore, it also includes an inner corner, a pop-out lever, a reaction spring, and a second locking block. The side cross-section of the crossbeam is a U-shaped structure with the opening facing downwards, and an inner corner with an L-shaped cross-section is fixedly connected to the inner side of both the front and rear parts at the lower end. The inner corner and the side of the crossbeam form an upward-opening channel structure. On the side of the inner corner near the middle of the inside of the crossbeam, a row of pop-out levers is installed at equal intervals. The lower end of the pop-out lever is inserted into the inside of the inner corner, and a circular second locking block is fixedly connected at the upper position of the insertion section. A reaction spring is sleeved on the end of the pop-out lever. The upper end of the reaction spring is sleeved on the lower end of the pop-out lever extension section and presses against the lower side of the second locking block. The lower end of the reaction spring presses against the bottom of the hollow structure inside the inner corner. The inner corner forms an upward-opening channel structure inside the crossbeam, which can store and hold cables passing through the crossbeam. When the cable is placed into the channel inside the crossbeam, the pop-out lever is pressed down to allow the cable to pass through. After releasing the hand, the pop-out lever automatically pops out under the action of the reaction spring, achieving the effect of securing the cable and ensuring the stability of the cable running inside the crossbeam.

[0011] Furthermore, it also includes a cable tray and a connecting hole. The inclined beam has a cable tray with a cross-section of an equilateral triangle inside. The cable tray is connected to a square through hole. A connecting hole is located on the inner side of the middle section of the inclined beam, at the junction with the crossbeam. The channel formed by the inner corner of the inclined beam and the crossbeam is connected to the inside of the cable tray through the connecting hole. The connecting hole is used to connect the cable trays inside the crossbeam. Cables placed in the inner channel of the crossbeam are introduced into the cable tray through the connecting hole. The cable tray inside the inclined beam is used for downward connection of photovoltaic cables.

[0012] Furthermore, it also includes a movable cover, a telescopic rod, a locking block, and a tension spring. A slit is provided at the middle position of the lower end of the inclined beam, and a movable cover with a V-shaped cross-section is provided at the slit. When the movable cover is closed, it remains flush with both sides of the inclined beam. Two telescopic rods are provided on the inner side of the middle section of the inclined beam. The upper end of the telescopic rod is vertically fixedly connected to the inner top side of the inclined beam, and the lower end of the telescopic rod is fixedly connected to the middle channel inside the movable cover. A locking block is fixedly connected at the upper part of the lower movable section of the telescopic rod. A tension spring is sleeved on the outside of the upper fixed section of the telescopic rod. The upper end of the tension spring is fixedly connected to the inner top side of the movable cover, and the lower end of the tension spring is fixedly connected to the upper side of the locking block. The intersecting area of ​​the internal channels of the inclined beam and the cross beam provides a wiring location for photovoltaic cables, thereby enabling electrical connection between the transmission cables and the lead-out ends of the photovoltaic modules; the telescopic rod is used to connect the movable cover to the inclined beam and allows the movable cover to be pulled down to expose the wiring area for workers to perform wiring operations; under the action of the tension spring, after the worker releases their hand, the movable cover can automatically close with the interface, thereby achieving concealed storage of the cables in the internal cable tray of the inclined beam.

[0013] Furthermore, it also includes a second connecting hole and a second cable tray. A second connecting hole is provided on the lower side of both ends of the inclined beam, at the location where it connects with the two inclined supports. A second cable tray is provided inside each of the two inclined supports, and the second cable tray is connected to the first cable tray through the second connecting hole. The second connecting hole is used for communication between the first and second cable trays, allowing the cable in the first cable tray to pass through the second connecting hole and continue to be laid downwards along the second cable tray inside the inclined support.

[0014] Furthermore, it also includes a detachable side plate. An outwardly expanding slot is provided on the right-facing side of the inclined support rod, which is connected to the cable routing groove. The detachable side plate is installed inside the slot and is fixedly connected to the inclined support rod by screws at its four corners. The detachable side plate allows for further routing of photovoltaic cables inside the inclined support rod.

[0015] Furthermore, it also includes hand-operated grooves, with one groove on each of the left and right sides of the movable cover. The hand-operated grooves facilitate the worker's downward pulling of the movable cover.

[0016] Furthermore, it also includes a vertical channel. A vertical channel is provided at the middle position of the inner arc surface of the Ω-shaped mounting bracket, and the upper end of the vertical channel is connected to the lower oblique section of the second wiring channel. By connecting the vertical channel to the second wiring channel inside the inclined support rod, the photovoltaic cable can be further laid down to the ground, and the overall cable can be concealed and stored, effectively protecting the photovoltaic cable.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This concealed storage structure for photovoltaic cables has the following advantages:

[0018] 1. Utilizing the hollow support structure of the photovoltaic panel, while providing installation support for the photovoltaic panel, the interconnected channel structure can conceal and lay the photovoltaic cable, effectively protecting the photovoltaic cable.

[0046] The working principle of the concealed photovoltaic cable storage structure provided by this invention is as follows: A horizontal beam 2 supports the photovoltaic panel, and an inclined beam 1 is used for the installation and support of the horizontal beam 2. The inclined beam 1, horizontal beam 2, and inclined support rod 3 constitute the main support frame. Two mounting brackets 4 are arranged in a ring and are bolted to the outside of the prefabricated columnar pile, thereby realizing the installation and fixation between the frame structure and the external pile. Utilizing the hollow support structure of the photovoltaic panel, while providing installation support for the photovoltaic panel, the photovoltaic cable can be concealed and laid through interconnected channel structures: Channel structures for storing photovoltaic cables are opened on the inner sides of the inclined beam 1, horizontal beam 2, inclined support rod 3, and mounting brackets 4, and these channels are interconnected, allowing the photovoltaic cable to be laid down step by step, ensuring that each section of cable can be concealed and effectively protecting the photovoltaic cable. The crossbeam 2 used to support the photovoltaic panel is equipped with multiple removable blocks 24 that can be selected as needed. After removing the removable blocks 24, the cable on the back of the photovoltaic panel can be introduced into the crossbeam 2. The crossbeam 2 is equipped with a pop-out locking rod 26, which makes it easy to lock the introduced cable at the inner corner 25 on the inner side of the crossbeam 2. When locking the cable into the channel inside the crossbeam 2, the pop-out locking rod 26 is pressed down to allow the cable to pass through. After releasing the hand, the pop-out locking rod 26 automatically pops out under the action of the reaction spring 27, realizing the locking effect of the cable and ensuring the stability of the cable running inside the crossbeam 2. The intersecting area of ​​the internal channels of the inclined beam 1 and the crossbeam 2 provides a wiring location for photovoltaic cables, thereby realizing the electrical connection between the transmission cable and the lead-out end of the photovoltaic module. An automatically resetting movable cover 13 is provided at this wiring location. Pulling down the movable cover 13 exposes the wiring area, facilitating wiring by workers. Under the action of the tension spring 16, the movable cover 13 automatically closes with the interface after the worker releases their hand, effectively protecting the wiring end. Furthermore, the crossbeam 2 is snapped into the inclined beam 1 via a snap-fit ​​interface 21. The hexagonal socket bolts 22 are tightened into the threaded holes 11, thus achieving a fixed connection between the crossbeam 2 and the inclined beam 1 based on the snap-fit ​​connection. The threaded holes 11 arrayed along the edge of the inclined beam 1 provide additional installation positions for the crossbeam 2, allowing the number of crossbeams 2 to be increased as needed. By cutting the connecting short blocks on all four sides of the removable stop block 24 on the middle side with pliers, the removable stop block 24 can be removed from the crossbeam 2, exposing the square through hole 10, thus allowing the photovoltaic panel to be installed. After installation, the main cable on the back of the photovoltaic panel is directly aligned and inserted into the square through hole 10 for concealment. By removing the removable stop block 24 on the edge side, holes can be provided for other cables on the back of the photovoltaic panel to pass through into the beam 2. The first connection hole 18 is used to connect the cable routing groove 12 inside the beam 2, and the second connection hole 19 is used to connect the cable routing groove 12 and the cable routing groove 31. A vertical groove 41 connected to the cable routing groove 31 is opened inside the mounting bracket 4, so that the photovoltaic cable can be routed downwards step by step.
