In traditional photovoltaic power stations, cables are usually laid in a simple overhead or direct buried manner. However, in the tea-photovoltaic complementary project, due to the special environmental requirements of tea planting and the structural characteristics of photovoltaic brackets, the traditional cable laying method has many problems.

[0003] First, overhead cables are easily affected by the natural environment, such as wind, sun, rain, etc., which accelerates the aging of cables and reduces their service life. At the same time, overhead cables will also affect the aesthetics of the tea garden, which is inconsistent with the ecological harmony concept pursued by the tea-light complementary project.

[0004] Secondly, although direct burying cables can avoid some external environmental influences, there are difficulties in the construction and maintenance process. Once the cable fails, large-scale excavation is required for repair, which is not only costly, but also detrimental to tea planting and will also damage tea trees before burying.

[0005] In addition, the traditional cable laying method is difficult to meet the orderly arrangement and protection requirements of cables between photovoltaic brackets in tea-solar complementary projects.

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] The following is combined with Figures 1 to 6 The present invention describes an inter-bracket cable trough box according to an embodiment of the present invention.

[0032] like Figures 1 to 6 As shown, the cable trough box between brackets of the embodiment of the present invention comprises a trough box body 1, a cover plate 2 and a connection component 3. Among them:

[0033] The trough box body 1 is made of high-strength, corrosion-resistant materials with good mechanical properties and protective properties. The shape design of the trough box body 1 matches the photovoltaic bracket and can be easily installed between the brackets without affecting the growth of tea and the normal operation of the photovoltaic module. The trough box body 1 is located between two adjacent purlins 100, and both ends of the trough box body 1 in the length direction are provided with openings, which allow the adjustment member 32 to enter from the outside of the trough box body 1 and extend to the inside; an inspection port is provided on the peripheral side of the trough box body 1 so that the cables inside the trough box can be inspected or maintained when necessary. A plurality of cable troughs for accommodating cables are provided inside the trough box body 1, and the plurality of cable troughs are independent of each other and not interconnected, so as to separate cables of different functions or specifications, fix the cables to prevent them from shaking in the trough box, and make the wiring beautiful and safe, ensure the neat arrangement and effective management of the cables, reduce the confusion and entanglement of the cables, so as to reduce the probability of failure and facilitate maintenance by the staff.

[0034] The material and size of the cover plate 2 should be designed to match the trough box body 1 to ensure that it can fit tightly on the trough box body 1 to prevent external factors such as dust and moisture from entering the interior of the trough box. The cover plate 2 can be detachably connected to the trough box body 1 and sealed at the inspection port. When the cable needs to be maintained or inspected, the cover plate 2 can be removed from the trough box body 1 to open the inspection port, which is convenient for the staff to operate.

[0035] The connecting component 3 includes at least two fixing members 31, at least two adjusting members 32 and at least two fasteners 33: the fixing member 31 is suitable for being installed at one end of the purlin 100 to provide a basis for connection, the fixing member 31 is provided with a limiting hole 311 for connecting with the adjusting member 32, the adjusting member 32 and the fixing member 31 correspond one to one, a part of the adjusting member 32 of the trough box body 1 enters and extends into the trough box body 1 through the opening, and is detachably connected with the trough box body 1, the adjusting member 32 is provided with a slide groove 321, the fastener 33 corresponds one to one with the adjusting member 32, the fastener 33 passes through the corresponding slide groove 321 and the limiting hole 311, so that the fastener 33 and the adjusting member 32 are detachably connected as a whole, and the adjusting member 32 can be adjusted to a certain extent on the fixing member 31 to adapt to purlins 100 of different spacings and / or heights, and can enable the cable trough box to withstand a certain amount of wind and external force impact, and has a seismic resistance function to ensure that the cable trough box operates stably in harsh natural environments.

[0036] When in use, after installing the fixing member 31 on the purlin 100, use the fastener 33 to penetrate the corresponding slide groove 321 and the limiting hole 311, and then make a part of the adjusting member 32 enter and extend into the trough box body 1 through the opening, and use bolts to detachably connect the adjusting member 32 to the trough box body 1, and then adjust the position and angle of the adjusting member 32 on the fixing member 31, so that the trough box body 1 is in a suitable position and then adjust the fastener 33 to complete the installation of the trough box body 1 between two adjacent purlins 100.

[0037] The cable trough box between the supports of the embodiment of the present invention reduces the damage of external physical, chemical and other factors to the internal cables without affecting the growth of tea leaves and the normal operation of photovoltaic components through the design of the trough box body 1 and the cover plate 2, and separates multiple cables from each other to avoid confusion, entanglement and the like of the cables, reduce the probability of failure and facilitate maintenance by staff; the cable trough box between the supports of the embodiment of the present invention can quickly complete the installation of the trough box body 1 through the design of the connecting component 3, and make the trough box body 1 adapt to purlins 100 of different heights, and will not cause damage to the photovoltaic supports and tea planting during the installation process, which greatly improves the construction efficiency and reduces the damage to tea trees.

[0038] Specifically, the present invention is particularly suitable for photovoltaic brackets in the same row of mountain tea-light complementary photovoltaic projects, where the horizontal distance between the ends of purlins 100 is not more than 1.9 meters and the height difference is not more than 0.6m. To ensure the mechanical strength of the cable trough box, the trough box body 1 should use a whole C90×40×15×1.5 C-shaped steel after cutting, and use a cover plate 2 matching the trough box body 1 to seal the trough box body 1; the fixing part 31 uses C90×40×15×1.5 C-shaped steel, and prefabricates a limiting hole with a size of 30mm×10mm and a chamfer radius of 5mm and two first fixing holes with a diameter of 10mm. The fixing part 31 uses M8×20 bolts and matching accessories to fix to the bracket purlin 100 through two first fixing holes, and is connected to the connecting part through the limiting holes; the adjusting part 32 uses 150×60×2.5 hot-dip galvanized steel plate, which is provided with two second fixing holes with a diameter of 10mm, and is connected to the fixing part 31 and the trough box body 1 respectively with M8×20 bolts and matching accessories. This design allows the installation of the cable trough box to be done in a quick connection manner, without the need for complex tools and professional technicians. The installation process will not cause damage to the photovoltaic support and tea planting, greatly improving construction efficiency, reducing damage to tea trees, and not affecting tea farmers' tea picking.

[0039] In some embodiments, the cable trough box between brackets further includes a heat dissipation component (not shown), which is connected to the trough box body 1 to dissipate heat for the cables in the trough box body 1. The heat dissipation component can be connected to the trough box body 1 by being directly fixed to the outer surface of the trough box body 1 or embedded in the structure of the trough box body 1. The specific form of the heat dissipation component can be selected according to actual needs, but it should be ensured that the sealing of the trough box body 1 is not affected while the heat in the trough box body 1 can be effectively conducted out, thereby keeping the cables within a suitable working temperature range.

[0040] In a specific embodiment, the heat dissipation assembly includes a plurality of heat sinks (not shown), a portion of the heat sinks is located inside the trough box body 1 , and another portion of the heat sinks is located outside the trough box body 1 .

[0041] The specific number and arrangement of the heat sink can be reasonably designed according to factors such as the size of the trough box body 1, the power density of the cable, and the required heat dissipation effect. The material of the heat sink should have good thermal conductivity and mechanical strength to ensure that the heat in the trough box body 1 can be effectively conducted away and withstand various mechanical stresses that may occur during use.

[0042] Inside the trough box body 1, the heat sink can maintain a certain contact or close distance with the cable to effectively absorb the heat generated by the cable. Outside the trough box body 1, the surface area of ​​the heat sink should be large enough to effectively dissipate the absorbed heat to the surrounding environment by natural convection or forced convection.

[0043] In addition, the connection method between the heat sink and the trough box body 1 should also have sufficient stability and durability to ensure that they will not loosen or be damaged during use. In specific applications, welding, bolt connection, snap connection, etc. can be used to achieve the connection between the heat sink and the trough box body 1.

[0044] like Figure 5 and Figure 6As shown, in some embodiments, one end of the cover plate 2 is rotatably connected to the trough box body 1, so that the cover plate 2 can be easily rotated on the trough box body 1 when needed, thereby realizing free switching of blocking and opening of the inspection port; the cable trough box between the brackets also includes at least one locking component 4, the locking component 4 is connected to the trough box body 1, and at least a part of the locking component 4 is movable relative to the trough box body 1, so that the locking component 4 has a locking position and an unlocking position, and can be freely switched between the locking position and the unlocking position; in the locked position, at least a part of the locking component 4 is against the cover plate 2 and the cover plate 2 is squeezed between the locking component 4 and the trough box body 1, so that the cover plate 2 keeps blocking the inspection port, at this time, the cover plate 2 cannot be easily opened so that external debris cannot easily enter the trough box body 1 from the inspection port; in the unlocked position, the locking component 4 is separated from the cover plate 2, and no longer exerts an extrusion effect on the cover plate 2, at this time, the cover plate 2 can be rotated on the trough box body 1 to freely switch the blocking and opening of the inspection port.

[0045] Therefore, the cable trough box between the brackets of the embodiment of the present invention is provided with the locking component 4, so that the staff can conveniently and quickly open or block the inspection port as needed: when the inspection port needs to be opened, it is only necessary to move the locking component 4 to the unlocking position and then rotate the cover plate 2; when the inspection port needs to be blocked, the cover plate 2 is rotated to the appropriate position and the locking component 4 is moved to the locking position.

[0046] like Figure 5 and Figure 6 As shown, in some embodiments, the lower end of the cover plate 2 is rotatably connected to the trough box body 1 through a rotating shaft arranged along the length direction of the trough box body 1 in the axial direction, so that when the locking assembly 4 is in the unlocked position, the cover plate 2 always keeps the inspection port open under the action of its own gravity.

[0047] It should be noted that when the locking assembly 4 is in the unlocked position, since the lower end of the cover 2 is connected to the trough box body 1 via a rotating shaft, and the setting direction of the rotating shaft makes the cover 2 tend to rotate downward under the action of its own gravity. Therefore, after the locking assembly 4 is unlocked and the cover 2 is separated from the inspection port, the cover 2 will automatically rotate downward under the action of its own gravity, and the inspection port will always be kept open, so that when the staff needs to open the inspection port, there is no need to apply additional force or add a fixing structure to the cover 2, and they only need to simply unlock the locking assembly 4.

[0048] like Figure 5 As shown, in a specific embodiment, the locking assembly 4 includes a first connecting member 41, a first locking member 42 and a first limiting member 43:

[0049] The first connecting member 41 is connected to the trough box body 1 and is located above the trough box body 1. The first connecting member 41 provides a stable supporting point for supporting the first locking member 42 and the first limiting member 43. The first connecting member 41 is provided with a first through hole arranged along the height direction of the trough box body 1 in the length direction. The first through hole acts like a guide rail, allowing the first locking member 42 to move along a fixed track.

[0050] A portion of the first locking member 42 is located in the first through hole and is movable along the length direction of the first through hole, so that the first locking member 42 can switch between a locked position and an unlocked position: insert the first locking member 42 into the first through hole and move downward along the first through hole until the first limit member 43 abuts against the first connecting member 41, at which time the locking assembly 4 is in a locked position, and the lower part of the first locking member 42 abuts against the cover plate 2, and the cover plate 2 is firmly locked on the trough box body 1 through physical contact. At this time, the cover plate 2 cannot be easily opened; pull the first locking member 42 out of the first through hole, at which time the locking assembly 4 is in an unlocked position, the first locking member 42 is completely separated from the cover plate 2, and the first locking member 42 no longer has any restraining effect on the cover plate 2. At this time, the cover plate 2 can rotate freely on the trough box body 1, which is convenient for the staff to open and block the inspection port.

[0051] The first limiting member 43 is connected to the first locking member 42 and is located above the first locking member 42 to limit the movement range of the first locking member 42 and prevent the first locking member 42 from falling after passing through the first through hole.

[0052] It should be noted that since the length direction of the first through hole is arranged along the height direction of the trough box body 1, when in the locked position, the first locking member 42 can overcome a certain degree of external interference (such as wind, external force impact, vibration, etc.) under the action of its own gravity and always remain in the locked position, reducing the possibility of accidental opening of the cover 2 and improving the safety of the cable trough box.

[0053] like Figure 6 As shown, in another specific embodiment, the locking assembly 4 includes a second connecting member 44, a connecting shaft 45 and a second locking member 46:

[0054] The second connecting member 44 is connected to the trough box body 1 and is located above the trough box body 1. The second connecting member 44 provides a stable supporting point for installing the connecting shaft 45 and supporting the connecting shaft 45 and the second locking member 46. The second connecting member 44 is provided with a second through hole arranged along the width direction of the trough box body 1 in the length direction, so that the connecting shaft 45 can rotate around the axis of the second through hole.

[0055] The axis of the connecting shaft 45 coincides with the axis of the second through hole, and a portion of the connecting shaft 45 is located in the second through hole and is rotatable on the second connecting member 44 , so that the connecting shaft 45 can drive the second locking member 46 to rotate.

[0056] The second locking member 46 is connected to one end of the connecting shaft 45 (such as Figure 6 The front end shown in the figure) is eccentrically arranged on the connecting shaft 45, so that the second locking member 46 produces an effect similar to moving up and down as the connecting shaft 45 rotates, thereby switching back and forth between the locked position and the unlocked position; the connecting shaft 45 is rotated so that most of the second locking member 46 is located below the connecting shaft 45, at this time the locking assembly 4 is in the locked position, and the lower part of the second locking member 46 is against the cover plate 2, and the cover plate 2 is firmly locked on the trough box body 1 through physical contact, at this time, the cover plate 2 cannot be easily opened; the connecting shaft 45 is rotated so that most of the second locking member 46 is located above the connecting shaft 45, at this time the locking assembly 4 is in the unlocked position, and the second locking member 46 is completely separated from the cover plate 2, at this time the cover plate 2 can rotate freely on the trough box body 1, which is convenient for the staff to open and block the inspection port.

[0057] It should be noted that since the second locking member 46 is eccentrically arranged on the connecting shaft 45, when in the locked position, the second locking member 46 can overcome a certain degree of external interference (such as wind, external force impact, vibration, etc.) under the action of its own gravity and always remain in the locked position, thereby reducing the possibility of accidental opening of the cover 2 and improving the safety of the cable trough box.

[0058] like Figure 6 As shown, optionally, the cross section of the second locking member 46 is semicircular, and the second locking member 46 is coaxially arranged with the connecting shaft 45 .

[0059] like Figure 6 As shown, further, the connecting shaft 45 is movable on the second connecting member 44 along the length direction of the second through hole. After the connecting shaft 45 is rotated so that most of the second locking member 46 is located above the connecting shaft 45, the connecting shaft 45 is moved so that the second locking member 46 is abutted against the upper end of the trough box body 1. The second locking member 46 can be kept in the unlocked position without applying additional force or adding additional fixing components. On the one hand, it is convenient for the staff to move and keep the locking assembly 4 in the unlocked position conveniently and quickly, and on the other hand, it avoids the interference of the second locking member 46 with the maintenance work; the locking assembly 4 also includes a second limiting member 47, and the second limiting member 47 is connected to the other end of the connecting shaft 45 (such as Figure 6 The rear end shown in the figure) is used to limit the movement range of the connecting shaft 45 to prevent the second locking member 46 from moving too far and thus failing to lock the cover plate 2 normally.

[0060] In some embodiments, a grounding cable is connected between the adjusting member 32 and the trough box body 1, and the purlin 100 and the adjusting member 32 are grounded by hot-dip galvanized flat steel welding or bolting, which is used to safely conduct static electricity or other charges on the trough box body 1 into the ground to prevent safety hazards such as electric shock and fire caused by charge accumulation.

[0061] In some embodiments, elastic seals (not shown) are provided between the purlin 100 and the fixing member 31, between the fixing member 31 and the adjusting member 32, between the adjusting member 32 and the trough box body 1, and between the trough box body 1 and the cover plate 2 to prevent harmful substances such as dust and water vapor from entering the interior of the trough box and affecting the safe operation of the cable.
