The sealing member integrally or separately extends from the main body section 12 to the installation space 90 between the adjacent photovoltaic modules 60, the first receiving surface 122 and the second receiving surface 123 are respectively located at two sides of the sealing member, the first receiving surface 122 is fixedly connected to the photovoltaic module 60 at one side, the second receiving surface 123 is fixedly connected to the photovoltaic module 60 at the other side, and the sealing member can seal the installation space 90 between the adjacent photovoltaic modules 60.

That is, the base 10 is used to support and connect two adjacent photovoltaic modules 60, the seal divides the main body section 12 into a first receiving surface 122 and a second receiving surface 123, the first receiving surface 122 is used to support and fix the side of one of the photovoltaic modules 60, and the second receiving surface 123 is used to support and fix the side of the other photovoltaic module 60. Further, the bases 10 are disposed at intervals along the extending direction of the purlines 80, so that the photovoltaic modules 60 can be mounted on the purlines 80 to cover the top surface of the shed.

It can be appreciated that by placing the sealing member in the installation space 90 between adjacent photovoltaic modules 60, it is advantageous to prevent rainwater from flowing from the installation space 90 between the photovoltaic modules 60 to below the photovoltaic modules 60, thereby achieving a good waterproof effect. In addition, the base 10 is fixed with the mounting frame 50 of the photovoltaic module 60 in advance, and then the base 10 is fixed on the purline 80, so that the time for high-altitude operation is reduced, and the construction efficiency and the construction safety are improved.

Specifically, as shown in fig. 1 to 4, the base main body 11 further includes a support section 113, and the support section 113 is used for connecting two ends of the main body section 12 and the placement section 112, so that the main body section 12 and the placement section 112 are kept in a spaced-apart opposite arrangement, and a cavity 111 is defined between the main body section 12, the support section 113 and the placement section 112. It should be noted that the cavity 111 is used for accommodating the wiring and the connector of the photovoltaic module 60, so that the wiring is more regular and hidden, and the aesthetic property of the shed is improved. Meanwhile, the base 10 can protect the wiring and the connector of the photovoltaic module 60, which is beneficial to avoiding the wiring and the connector from exposure and corrosion, thereby prolonging the service life of the wiring and the connector and improving the reliability of the photovoltaic system. In at least one embodiment, the height of the support section 113 is greater than 2.5cm to facilitate placement of the connector in the cavity 111.

In some embodiments, as shown in fig. 2-4, the body section 12 has a through hole 121 adapted for the passage of a fastener, the through hole 121 being disposed opposite the placement section 112 such that the fastener can pass through the through hole 121 and be fixedly attached to the placement section 112. That is, under the condition that the base 10 is placed on the purlin 80, the through hole 121 on the main body section 12 allows the fastener and the installation tool (for example, a screwdriver) to pass through, so that the installation operation of the constructor is facilitated, and the fastener can connect the placement section 112 and the purlin 80, so that the base 10 is fixed on the purlin 80. It should be noted that, as shown in fig. 1, under the condition that the fastener is installed on the placement section 112, the head of the fastener is accommodated in the cavity 111 between the main body section 12 and the placement section 112, so that the base 10 can shield the head of the fastener, which is beneficial to improving the aesthetic property of the shed and prolonging the service life of the fastener.

In at least one embodiment, as shown in fig. 1, under the condition that the photovoltaic module 60 is mounted on the base 10, the mounting frame 50 of the photovoltaic module 60 covers the through hole 121 on the main body section 12, which is beneficial to preventing rainwater from entering the cavity 111 from the through hole 121, so as to further improve the waterproof performance of the mounting device of the photovoltaic module.

In at least one embodiment, as shown in fig. 2-4, the through-holes 121 are elongated holes, and when the base 10 is placed on the purlin 80, the elongated holes extend in a direction perpendicular to the direction in which the purlin 80 extends, i.e., the direction in which the elongated holes extend is parallel to the width direction of the purlin 80, so that the position of the fasteners can be adjusted during installation so that the fasteners are as close to the middle of the purlin 80 in the width direction as possible.

In at least one embodiment, the base 10 and purlin 80 are secured by stainless steel self-tapping screws, which facilitates both adjusting the position of the stainless steel self-tapping screws relative to the purlin 80 and improving the efficiency of construction.

In some embodiments, as shown in fig. 2, the base 10 further includes at least one extension section 13, where the extension section 13 integrally extends from one side or both sides of the main body section 12 to the direction of the photovoltaic module 60, and the extension section 13 can extend the first receiving surface 122 and/or the second receiving surface 123, so as to increase the contact area between the base 10 and the photovoltaic module 60, improve the bearing capacity of the base 10, and further facilitate improving the structural reliability of the installation device of the photovoltaic module.

In some embodiments, as shown in fig. 2, the extension 13 has mounting holes 131 that fit into fasteners so that the compacts 20 can be fixedly attached to the extension 13 by the fasteners. It can be appreciated that, compared with the mounting hole 131 disposed in the main body section 12, in this embodiment, the extension section 13 extends from the main body section 12 to the photovoltaic module 60, so as to be located at the outer side of the base main body 11, and further the extension section 13 and the placement section 112 are arranged in a staggered manner, the mounting hole 131 is disposed in the extension section 13, which is beneficial to avoiding interference between the fastener and the mounting tool in the mounting process and the placement section 112 and the support section 113, so as to improve the convenience of the mounting operation. In addition, under the condition that the photovoltaic module 60 is mounted on the base 10, the photovoltaic module 60 can shield the extension section 13, that is, the fastener can be hidden under the photovoltaic module 60, thereby being beneficial to keeping the top surface of the shed clean and improving the aesthetic property of the shed.

In some embodiments, as shown in fig. 2 and 5, the pressing section 21 is provided with a connection hole 212, and the connection hole 212 is disposed opposite to the mounting hole 131 on the extension section 13 under the condition that the photovoltaic module 60 is mounted on the base 10, so that the pressing block 20 is fixed on the base 10 through the connection hole 212 on the pressing section 21 and the mounting hole 131 on the extension section 13 by using a fastener. Specifically, one end of the pressing block 20 abuts against the first bearing surface 122 or the second bearing surface 123 of the base 10 through the abutting section 22, and the other end of the pressing block 20 elastically abuts against the mounting frame 50 of the photovoltaic module 60, so that the mounting frame 50 of the photovoltaic module 60 is clamped between the pressing block 20 and the base 10.

In at least one embodiment, as shown in fig. 2, the mounting hole 131 on the extension section 13 is a unthreaded hole, the connecting hole 212 on the compression section 21 is a threaded hole, so that a bolt can pass through the mounting hole 131 on the extension section 13 and is screwed with the connecting hole 212 on the compression section 21 in a threaded fit manner, so that the photovoltaic module 60 is detachably mounted on the base 10, the operation is simple and convenient, the mounting efficiency is improved, the subsequent disassembly and replacement of the photovoltaic module 60 are facilitated, and the maintenance of a shed is improved. It should be noted that the connection hole 212 may be a light hole, which is not particularly limited in the present application.

In at least one embodiment, as shown in fig. 2 and 5, the pressing section 21 is further provided with a protruding portion 211, the protruding portion 211 is located on the peripheral side of the connecting hole 212, and the protruding direction of the protruding portion 211 is consistent with the extending direction of the connecting hole 212, so that the thickness of the pressing section 21 in the extending direction of the connecting hole 212 is increased through the protruding portion 211, which is beneficial to prolonging the screwing length of the fastener and the pressing section 21, and further is beneficial to improving the connecting strength of the pressing block 20 and the base 10.

In at least one embodiment, as shown in fig. 1-4, the epitaxial section 13 includes a first epitaxial section 132 and a second epitaxial section 133, the first epitaxial section 132 and the second epitaxial section 133 extending from opposite sides of the body section 12 in directions away from each other, respectively, to lengthen the first receiving surface 122 and the second receiving surface 123. Further, the first extension segment 132 and the second extension segment 133 are respectively provided with a mounting hole 131, two opposite sides of the photovoltaic module 60 are respectively provided with a mounting frame 50, wherein the mounting frame 50 on one side is connected with the first extension segment 132 through the pressing block 20, so that one side of the photovoltaic module 60 is fixedly supported on the first supporting surface 122, and the mounting frame 50 on the other side is connected with the second extension segment 133 through the bolts and nuts, so that the other side of the photovoltaic module 60 is fixedly supported on the second supporting surface 123.

In some embodiments, as shown in fig. 2 and 6, the sealing member includes a sealing strip 30, and the sealing strip 30 includes an adhesive segment 31, an upper sealing portion 32, and a lower sealing portion 33, and the adhesive segment 31 is adhered to the back surface of the mounting frame 50 of one of the photovoltaic modules 60. The upper seal portion 32 and the lower seal portion 33 are deformably extended from the adhesive segment 31 to the rear surface of the mounting frame 50 of the other side photovoltaic module 60, and the upper seal portion 32 is located above the lower seal portion 33. It can be appreciated that under the condition that the sealing strip 30 is mounted in the mounting space 90 between the adjacent photovoltaic modules 60, the upper sealing portion 32 and/or the lower sealing portion 33 are extruded by the mounting frame 50 of the photovoltaic module 60, so that elastic deformation occurs, so that the sealing strip 30 is sealed and filled in the mounting space 90, which is beneficial to avoiding rainwater from flowing from the mounting space 90 to the lower side of the photovoltaic module 60, and improving the waterproof performance of the shed.

It should be noted that, in the present embodiment, compared with the case of plugging the sealing strip 30 after the photovoltaic module 60 is mounted, the sealing strip 30 and the mounting frame 50 are pre-fixed by the bonding section 31, so that the time of overhead operation is reduced, and the displacement of the sealing strip 30 during the handling and mounting process is avoided, thereby improving the construction efficiency.

In some embodiments, as shown in fig. 6, the outward extent of the upper seal portion 32 is greater than the lower seal portion 33, such that the deformability of the upper seal portion 32 is greater than the lower seal portion 33. It will be appreciated that, under the condition that the sealing strip 30 is installed in the installation space 90 between the adjacent photovoltaic modules 60, the upper sealing portion 32 is located at a side far away from the base 10, and the lower sealing portion 33 is located at a side close to the base 10, that is, rainwater will contact the upper sealing portion 32 first, and the radian of the upper sealing portion 32 extending outwards is increased, so that the upper sealing portion 32 has a larger deformability, and further, the contact length between the deformed upper sealing portion 32 and the installation frame 50 of the photovoltaic module 60 is increased, which is beneficial to improving the sealing effect, and further improving the waterproof performance of the installation device of the photovoltaic module. The variability of the lower sealing part 33 is small, so that the lower sealing part 33 has better supporting property, the structural strength of the sealing strip 30 is improved, and the sealing strip 30 is prevented from excessively deforming as a whole. In at least one embodiment, the upper ends of the sealing strips 30 do not exceed the mounting frame 50 under the condition that the sealing strips 30 are mounted in the mounting space 90 between adjacent photovoltaic modules 60, to improve the aesthetic and tidy nature of the shed.

It should be noted that, under the condition that the upper sealing portion 32 and the lower sealing portion 33 are pressed by the mounting frame 50, the upper sealing portion 32 and the lower sealing portion 33 can provide the force to the bonding section 31 towards the mounting frame 50 bonded by the bonding section 31, which is beneficial to avoiding the peeling between the bonding section 31 and the mounting frame 50 due to the gradual failure of the adhesive, and improving the reliability of the mounting device of the photovoltaic module.

It should be noted that the cross section of the sealing strip 30 may be other shapes that can fill the installation space 90, such as a "convex" shape, a trapezoid shape, a rectangular shape, and the sealing strip 30 may be implemented as a rubber plug, which is not particularly limited in the present application.

In some embodiments, as shown in fig. 2-4, the seal further includes a spacing segment 14, the spacing segment 14 integrally extending from the body segment 12 toward the mounting space 90 between adjacent photovoltaic modules 60, the spacing segment 14 being configured to support the lower seal portion 33 of the seal strip 30 such that the seal strip 30 is deformably clamped between adjacent photovoltaic modules 60. It can be understood that the first receiving surface 122 and the second receiving surface 123 are respectively located at two sides of the limiting section 14, in the arrangement direction along the first receiving surface 122 and the second receiving surface 123, the size of the limiting section 14 is smaller than or equal to the size of the sealing strip 30 in the free state, further, under the condition that the adjacent photovoltaic modules 60 are mounted on the base 10, the mounting frames 50 of the two photovoltaic modules 60 respectively press against two sides of the limiting section 14, so that the width of the mounting gap 90 between the adjacent photovoltaic modules 60 is close to or consistent with the size of the limiting section 14, so that the width of the mounting gap 90 is smaller than the size of the sealing strip 30 in the free state, and the sealing strip 30 is elastically deformed to be accommodated in the mounting gap 90 to play a role of sealing and waterproofing. The dimension of the sealing strip 30 in the free state refers to the maximum distance from the upper sealing portion 32 to the bonding portion along the arrangement direction of the first receiving surface 122 and the second receiving surface 123.

That is, the spacing section 14 plays a role in assisting positioning so as to control the size of the installation gap 90, thereby being beneficial to improving the repeatability and operability of the installation of the photovoltaic module 60, further improving the construction efficiency, and enabling the spacing between the photovoltaic modules 60 to be more uniform through the assisting positioning of the spacing section 14, and improving the aesthetic property of the shed. It should be noted that, in the drainage direction, that is, in the oblique direction of the roof surface of the vehicle shed, the limiting section 14 on the base 10 can be abutted against the lower side edge of the photovoltaic module 60, which is favorable for avoiding the photovoltaic module 60 from sliding downwards, so as to improve the convenience and safety of construction.

In some embodiments, as shown in fig. 10 and 11, the sealing member further includes a clamping section 15, where the clamping section 15 extends from an end of the limiting section 14 away from the main body section 12 toward one side or both sides, such that the clamping section 15 is disposed opposite the first receiving surface 122 and/or the second receiving surface 123, and the mounting frame 50 of the photovoltaic module 60 is accommodated between the clamping section 15, the limiting section 14, and the main body section 12. That is, a "匚" structure is formed between the clamping section 15, the limiting section 14 and the first receiving surface 122 and/or between the clamping section 15, the limiting section 14 and the second receiving surface 123, and three sides of the installation frame 50 of the photovoltaic module 60 are respectively abutted against the clamping section 15, the limiting section 14 and the receiving surface, so that the photovoltaic module 60 is clamped on the base 10, and the installation frame 50 of the photovoltaic module 60 is in sealing connection with the base 10, which is beneficial to avoiding rainwater from flowing from between the photovoltaic module 60 and the installation frame 50 to the lower surface of the photovoltaic module 60.
