[0017] ​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0018] Embodiment 1

[0019] As Figure 1 shown, the suspension type FRP photovoltaic support is used for being installed on a wall 1' having a railing 131' and carrying a photovoltaic panel a. Specifically, the wall 1' includes a wall 11', an extension body 12' formed on the wall 11' and extending outward (the extension body 12' can be any structure protruding from the wall 11' such as a balcony), and a guardrail 13' installed on the extension body 12' (the guardrail 13' can be any shielding or protective structure capable of being installed on the extension body 12'), the guardrail 13' having a transversely arranged railing 131'.

[0020] The above suspension type FRP photovoltaic support includes at least two groups of carrying units 1 arranged in parallel and spaced apart, and the number of the carrying units 1 is generally determined according to the size of the layout space, the size of the photovoltaic panel a and other factors. In this embodiment, the carrying units 1 are four groups. Each group of carrying units 1 includes a support seat 13 installed on the surface of the wall 1', a closed hook 15 buckled on the railing 131', and a support beam 11. The carrying unit 1 further includes a support rod 12 having one end connected to the support seat 13 and the other end connected to the lower end of the support beam 11 (i.e. the support beam 11 is indirectly connected to the support seat 13 through the support rod 12).

[0021] In this embodiment, the support seat 13 can be any conventional mounting seat structure capable of being firmly mounted on the wall 11' (such as using expansion screws, etc.), such as the support seat 13 including a bottom plate mounted on the wall 11' and a support plate formed on the bottom plate and perpendicular thereto. The support plate is usually located at the edge of the bottom plate so that the cross section of the support seat 13 is angular (right angle). The free end of the support plate is formed with two inclined surfaces extending outwardly in opposite directions, so as to reduce the use of raw materials and reduce the weight (as shown in Figure 2

[0022] ​In the embodiment, the material of the support beam 11 is glass fiber reinforced plastic, so that the FRP photovoltaic support has the advantages of strong designability, simple structure, easy installation, high specific strength, light self-weight, effectively reducing the bearing pressure of the main building, corrosion resistance and good stability; the tensile, compressive and bending strength of the glass fiber reinforced plastic is preferably not less than 700 MPa, the tensile, compressive and bending modulus of elasticity is not less than 40 GPa, and the performance decreases by not more than 10% under 30 years of ultraviolet aging test (the same below). The support beam 11 includes a first connecting plate 111, a second connecting plate 112 and a third connecting plate 113, the first connecting plate 111 and the second connecting plate 112 are arranged in parallel and spaced apart; the third connecting plate 113 is formed at the edge of the first connecting plate 111 and the edge of the second connecting plate 112 to connect the first connecting plate 111 and the second connecting plate 112 (here, the formation is usually one-piece), so that the first connecting plate 111 and the second connecting plate 112 are on the same side of the third connecting plate 113, and the third connecting plate 113 is perpendicular to the first connecting plate 111 or the second connecting plate 112; as shown in Figure 4 , the width of the first connecting plate 111 is defined as D, the width of the second connecting plate 112 is defined as d, and D>d, so as to improve the overall strength of the support beam 11 and increase the load capacity of the photovoltaic panel a. In use, the photovoltaic panel a is installed on the outer surface of the third connecting plate 113 (i.e. the surface away from the first connecting plate 111 or the second connecting plate 112).

[0023] In the embodiment, the upper end of the support beam 11 is connected with the closed hook 15 (which can be directly connected, but is preferably indirectly connected here), because the bearing unit 1 further includes an adapter plate 14 connecting the support beam 11 and the closed hook 15, the adapter plate 14 has a first plate piece 141 and a second plate piece 142 integrally connected and forming an angle (the angle is usually a right angle, so the adapter plate 14 is a conventional right angle steel), the first plate piece 141 is connected with the support beam 11 (specifically the first connecting plate 111 of the support beam 11) through a plurality of (such as 2 or more) first connecting pieces 143 (which can be a conventional bolt pair), so that the inner surface of the first connecting plate 111 is in contact with the outer surface of the first plate piece 141. The closed hook 15 includes a hook 151 connected with the second plate piece 142 through a second connecting piece 152 (there is at least one here, which can also be a conventional bolt pair), and a limiting connecting piece 153 connecting the second plate piece 142 and the hook 151 and enclosing the hook part of the hook 151 (as shown in Figure 3 , so that the hook 151 of the closed hook 15 can be buckled on the railing 131' and cooperated with the limiting connecting piece 153 to realize closure and avoid the closed hook 15 from falling off the railing 131' (the limiting connecting piece 153 can be a conventional one, such as a light rod bolt pair).

[0024] In the embodiment, each set of bearing units 1 further comprises a support rod 12 connected at one end to the support base 13 and at the other end to the lower end of the support beam 11, i.e. the lower end of the support beam 11 is connected to the other end (i.e. the free end or outer end) of the support rod 12 by a conventional connecting member; the connection here is achieved by a conventional connecting member such as a bolt pair, which can be a fixed connection, but is more preferably a pivot connection. The support rod 12 is a single support rod 121 or a plurality of support rods 121 connected by a plurality of third connecting members 122, so that the angle between the support beam 11 and the guardrail 13' can be adjusted by adjusting the length of the support rod 121, the number of support rods 121 or / and the degree of overlap of the support rods 121 (the angle is 10-60°, preferably 45-60°). Specifically, the support rod 121 is preferably two, each of which is provided with a plurality of connecting holes 1211 spaced apart in the length direction thereof, so that when the two support rods 121 partially overlap, at least two sets of connecting holes 1211 are overlapped, and a corresponding number of third connecting members 122 (using conventional connecting members such as bolt pairs) are inserted through the at least two sets of connecting holes 1211 to achieve connection. The material of the support rod 121 is also preferably glass fiber reinforced plastic and has the same structure as the support beam 11, but care should be taken that the two support rods 121 do not interfere with each other when they are connected.

[0025] Embodiment 2

[0026] The embodiment provides a suspended FRP photovoltaic support, which is basically the same as that in Embodiment 1, except that it lacks a support rod 12; so the lower end of the support beam 11 is directly connected to the support base 13 by a conventional connecting member (such as a conventional bolt pair) (specifically, the connecting member connects the first connecting plate 111 and the support plate, so that the outer surface of the first connecting plate 111 is in contact with the inner surface of the support plate). At this time, the angle adjustment between the support beam 11 and the guardrail 13' is only 5-10°, mainly affected by the size of the support base 13.

[0027] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent substitutions or changes to the technical scheme and the inventive concept of the present application within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
