Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic building integration, and more specifically to a photovoltaic carport. Background Art

[0002] In the existing photovoltaic carport technology, in order to effectively solve the problem of water seepage caused by the assembly gap between photovoltaic modules, it is generally adopted to set additional drainage grooves between adjacent photovoltaic modules. Usually, it includes a W-shaped water guide groove set between adjacent photovoltaic modules and a U-shaped water guide groove set on the side of the photovoltaic panel. The water flow of several W-shaped water guide grooves is uniformly collected in the U-shaped water guide groove and then flows to the lower end of the carport, thereby preventing rainwater from penetrating under the photovoltaic modules and causing damage or safety hazards.

[0003] However, the existing drainage methods have high installation and maintenance costs and require precise measurement and positioning to ensure that they fit tightly with the photovoltaic panels and there are no leaks. They also increase the overall weight and complexity of the photovoltaic carport, which is not conducive to the lightweight design and installation of the carport. Utility Model Content

[0009] The utility model is further configured as follows: two upright posts are connected to the bottom of the crossbeam, wherein one upright post is higher than the other, thereby causing the crossbeam to tilt.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] A photovoltaic carport, such as Figure 1 and Figure 2 As shown, it includes interconnected columns 2 and beams 1, the beam 1 is fixed obliquely on the top of the column 2, and a number of photovoltaic modules 3 are laid on the beam 1 along its length. The upper end and the lower end of the photovoltaic module 3 are fixed to the beam 1 through a first connector 4 and a second connector 5 respectively. The height of the first connector 4 is smaller than the height of the second connector 5, so that the distance between the upper end of the photovoltaic module 3 and the beam 1 is smaller than the distance between the lower end and the beam 1, and an angle is formed between the photovoltaic module 3 and the beam 1. The lower end of the photovoltaic module 3 is stacked above the upper end of the adjacent photovoltaic module 3, so that the roof forms a continuous water-conducting slope. The accumulated water can flow from the top to the bottom, and then flow to the ground from the edge of the bottom end of the roof. There is no need to set a water guide trough between the photovoltaic modules 3.

[0028] The first connecting member 4 is a low purlin, and the second connecting member 5 is a high purlin. The height of the high purlin is greater than that of the low purlin. The bottoms of the low purlin and the high purlin are connected to the beam 1, and the tops are connected to the photovoltaic module 3, thereby raising the lower end of the photovoltaic module 3 to a higher height, forming an angle between it and the beam 1.

[0029] like Figure 3 and Figure 4 As shown, a slide groove 6 is opened at the top of the beam 1 along its length direction, and a number of blocks 7 are arranged in the slide groove 6. The two sides of the blocks 7 are clamped and limited with the top end of the slide groove 6, and cannot escape from the slide groove 6 in the vertical direction. There is a block 7 corresponding to each purlin on both sides, which are respectively passed through the wing plates at the bottom of the low purlin and the high purlin by bolts, and then penetrate into the slide groove 6 and are threadedly connected with the blocks 7. Since the shape of the blocks 7 corresponds to the slide groove, the blocks 7 cannot rotate in the slide groove 6. Therefore, when the bolts are rotated, the blocks 7 will move upward to abut against the top end of the slide groove 6, and the bolts will press against the wing plates, clamping the wing plates on the beam 1, thereby realizing the connection between the low purlin and the high purlin and the beam 1.

[0030] like Figure 1 、 5 As shown in Figure 6, the tops of the low purlins and the high purlins are fixed with fasteners 8 by bolts, and the bottom edge of the photovoltaic module 3 has a convex edge 9 protruding inward. The fasteners 8 are pressed against the convex edge 9 by tightening the bolts, thereby realizing the connection between the low purlins and the high purlins and the photovoltaic module 3.

[0031] Two columns 2 are connected to the bottom of the beam 1, one of which is higher than the other, so that the beam 1 is tilted. The beam 1 is provided with two parallel ones, and the two ends of the low purlin and the high purlin are respectively fixed on the two beams 1. In this embodiment, three groups of photovoltaic modules 3 are laid on the beam 1. The photovoltaic modules 3 are composed of three photovoltaic panels 301. The three photovoltaic panels 301 are spliced ​​along the length direction of the purlin. Each photovoltaic panel 301 is fixed to the low purlin and the high purlin by a fastener 8.

[0032] An L-shaped plate 302 is provided at the bottom end of one side of the photovoltaic panel 301, and a baffle plate 303 is provided at the top end of the other side. The L-shaped plate 302 and the baffle plate 303 extend from the higher end to the lower end of the photovoltaic panel 301. The length of the L-shaped plate 302 and the baffle plate 303 is the same as that of the photovoltaic panel 3011. When the photovoltaic panel 301 is fitted with the adjacent photovoltaic panel 301, the baffle plate 303 covers the L-shaped plate 302 of the adjacent photovoltaic panel 301, and the photovoltaic panel 301 is located above the L-shaped plate 302 and is further provided with a positioning plate 304. When the photovoltaic panel 301 is fitted with the adjacent photovoltaic panel 301, the bottom of the baffle plate 303 just fits on the positioning plate 304. After the photovoltaic panels 301 are spliced, water flows down from the gap between the adjacent photovoltaic panels 301 and will gather in the L-shaped plate 302, and flow along the L-shaped plate 302 to the photovoltaic component 3 below.

[0033] like Figure 7 As shown, the column 2 includes an outer tube 202 and an inner rod 203 slidably connected to the outer tube 202. Both the outer tube 202 and the inner rod 203 are rectangular parallelepipeds. The sidewall of the inner rod 203 is provided with a plurality of adjustment holes 204 in the vertical direction. The outer tube 202 is provided with an adjustment bolt. Specifically, the sidewall of the outer tube 202 is provided with a through hole. The adjustment bolt passes through the through hole of the tube and then into the adjustment hole 204 of the inner rod 203 to achieve relative fixation of the inner rod 203 and the outer tube 202. The height of the column 2 can be adjusted by sliding the inner rod 203 and inserting the bolt into the adjustment hole 204 at different heights of the inner rod 203. Since the distance between adjacent adjustment holes 204 is the same, the height difference between the front and rear columns 2 can be maintained by simply changing the number of holes by the same amount during adjustment.

[0034] The column 2 also includes a base 201, which is fixed to the ground by bolts. The base 201 has a sleeve protruding upward, and the bottom of the outer tube 202 is sleeved on the base 201. The bottom of the outer tube 202 and the base 201 are provided with corresponding through holes, which are fixed by bolt connection. The peripheral side wall of the inner rod 203 fits with the inner wall of the outer tube 202, and the peripheral side wall of the base 201 also fits with the inner wall of the outer tube 202.

[0035] The beam 1 and the column 2 are connected by a first corner seat 10 and a second corner seat 11. One side of the first corner seat 10 and the second corner seat 11 is fixed to the side wall of the column 2 by bolts, and the other side is fixed to the bottom of the beam 1 by bolts, so that the beam 1 is fixed to the column 2. The first corner seat 10 is fixed to the side of the column 2 that is inclined upward toward the beam 1, and the second corner seat 11 is fixed to the side of the column 2 that is inclined downward toward the beam 1. Therefore, the angle of the first corner seat 10 is greater than 90°, and the angle of the second corner seat 11 is less than 90°. The angle of the corner seat connector with the corresponding angle can be selected according to the inclination angle of the beam 1. In this embodiment, the angle of the first corner seat 10 is 96°, and the angle of the second corner seat 11 is 84°.

[0036] The working process of this utility model is as follows:

[0037] The accumulated water on the roof will flow downward along the inclined surface formed by the photovoltaic components 3 until it flows out from the lower edge of the roof. When the water seeps down between adjacent photovoltaic panels 301, the water will gather on the L-shaped plate 302 and flow along the L-shaped plate 302 to the photovoltaic components 3 below. If the staff needs to adjust the height of the roof when installing the carport, they can slide the inner rod 203 in the vertical direction, adjust it to the appropriate position, align the adjustment hole 204 with the through hole on the outer tube 202, and then pass the bolt through the through hole and the adjustment hole 204 to complete the relative fixation of the inner rod 203 and the outer tube 202, thereby achieving height adjustment.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
