Description

Streamline type overwater photovoltaic array support and mounting method thereof

Technical Field

The invention relates to a solar photovoltaic array, in particular to a streamline waterborne photovoltaic array bracket and an installation method thereof.

Background

Solar photovoltaic power generation is a technology of receiving incident sunlight by using an array formed by a solar photovoltaic module system, converting light energy into electric energy by photovoltaic conversion, and collecting the generated electric energy for use. In terms of field, an unmasked water surface is also an ideal field for the photovoltaic system to utilize solar energy. For example, fig. 15 shows a simplified schematic of a photovoltaic array rack suitable for installation on a water surface, including a photovoltaic panel 1100 of a photovoltaic module subsystem, a photovoltaic rack 1300 supporting the photovoltaic panel 1100, a pontoon 1500, and a column 1700 mounting the rack 1300 on the pontoon 1500. However, in the overwater photovoltaic array shown in fig. 15, the photovoltaic panels 1100 are inclined facing the same direction, which is also called a unidirectional assembly arrangement, and the arrangement is similar to a semi-open shutter blade, and when a strong wind is encountered, the shape coefficient of a wind load is large, and the safety of the whole array bracket is seriously influenced. Secondly, the distance between the front and the back adjacent photovoltaic panels needs to be set to be larger, so that the photovoltaic panel positioned at the back is not blocked by the photovoltaic panel inclined upwards at the front, particularly in high-latitude areas, the distance between the front and the back adjacent photovoltaic panels is set to be larger, the water surface utilization rate is greatly reduced, and the construction cost is greatly increased. In addition, the orientation of the photovoltaic panels is uniformly fixed towards the south (northern latitude area) or the north (southern latitude area), so that the photovoltaic panel can not perfectly adapt to the actual situation of a photovoltaic array field, and the problems that part of water areas cannot be utilized or the utilization rate is low are easily caused.

Detailed Description

A more complete understanding of the present application can be obtained by reference to the following detailed description of the present application, taken in conjunction with the accompanying drawings that set forth non-limiting embodiments. Also, the following description omits descriptions of well-known raw materials, processing techniques, components, and apparatuses so as not to unnecessarily obscure the technical points of the present application. However, those of ordinary skill in the art will understand that the description and specific examples, while indicating embodiments of the present application, are given by way of illustration and not limitation. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

Fig. 1 is a schematic view showing a streamlined photovoltaic array support on water according to an embodiment of the present invention, and fig. 2 is a schematic perspective view showing a group of photovoltaic supports among the photovoltaic array supports shown in fig. 1. Referring to fig. 1 and 2 in combination, the streamlined above-water photovoltaic array support comprises at least one pair of pontoons, preferably, for example, rectangular pontoons 11, purlins 12 arranged, for example, in parallel between the pair of rectangular pontoons 11, and pairs of photovoltaic modules 13 arranged on the purlins 12, each pair of photovoltaic modules 13 of the pairs of photovoltaic modules 13 being arranged inclined in a substantially mirror image manner, in a streamlined design.

Fig. 3 is a partially enlarged schematic view of the photovoltaic rack shown in fig. 2, fig. 4 is a schematic view showing the photovoltaic rack shown in fig. 2 along a length direction of a purlin, and fig. 5 is a partially enlarged schematic view of the photovoltaic rack shown in fig. 4. With combined reference to fig. 3 to 5, the rectangular pontoon 11 is for example made of a foam material as a main body, the outer surface being for example clad aluminium alloy plate. The side surface of the float 11 is provided with through holes along the transverse direction for example, so as to penetrate through the purline 12. Although the through-holes are shown as being square in shape, it will be understood by those skilled in the art that the shape of the through-holes may be dependent on the cross-section of the purlin 12, and may be, for example, square, circular, or other shapes. Preferably, the purlin 12 is perforated, for example transversely, on the side close to the pontoon 11, with a pin or screw 121 to be positioned with the pontoon 11 against slipping out of the latter. It will be appreciated by those skilled in the art that the buoy 11 is fixed to the surface, for example by means of a chain.

Each pair of the photovoltaic modules 13 arranged on the purlins 12 is respectively arranged on two sides of the rectangular buoy 11, for example, wherein each pair of the photovoltaic modules 13 comprises a first end 132 at a higher position and a second end 131 at a lower position relative to the horizontal position of the purlins 12 when being installed. The second end 131 of the photovoltaic module 13 is secured to the purlin 12 at a location remote from the pontoon 11 by a lower module mount 135, and preferably the second end 131 is connected to the lower module mount 135, such as by a module connector 134. The first end 132 of the photovoltaic module 13 is located, for example, near above the pontoon 11. Each pair of photovoltaic modules 13, which are separated on either side of the pontoon 11, comprises, for example, a left-hand module 137 and a right-hand module 138, the first ends 132 of which are connected to the purlins 12, for example, by module supports 136. The support member 136 is, for example, a V-shaped metal member, the bottom of which is mounted on the purlin 12 near the pontoon 11 by a connector such as a bolt or a rivet, and the top of which is connected to the first end 132 of the photovoltaic module 13 by a connector such as a rivet or a bolt. The horizontal position of the first end 132 of the photovoltaic module can be set higher than the horizontal position of the second end 131 of the module, preferably such that the included angle between the panel of the photovoltaic module 13 and the purlin 12 is greater than 0 degrees and less than or equal to 60 degrees, preferably, the included angle is set to be, for example, between 5 and 30 degrees. Those skilled in the art will appreciate that the tilt angle of the photovoltaic module can be adjusted by designing and adjusting the height of the module support 136 and/or the module connector 134. In the above solution, the left side assembly 137 and the right side assembly 138 are respectively disposed at both sides of the pontoon 11, that is, the pontoon 11 is located substantially in the middle region of the left side assembly 137 and the right side assembly 138. It will be appreciated by those skilled in the art that the pontoons 11 may also be located, for example, to the left or right of the mid-section described above.

According to the streamline overwater photovoltaic array bracket, the movement characteristic of natural wind can be fully adapted, the wind load borne by the whole photovoltaic array bracket is greatly reduced, and the safety and the stability of the bracket are ensured. For example, when the left side component 137 on the bracket faces the wind, it is subjected to the positive pressure generated when the natural wind passes through, and at the same time, the right side component 138 is subjected to the negative pressure generated when the natural wind passes through, but because the two components are arranged in a streamline form relative to the mirror image of the buoy 11, the resistance to the wind movement is greatly reduced, thereby further reducing the influence of the wind load on the underwater anchoring system and ensuring the reliable operation of the photovoltaic array.

In particular, the pair of photovoltaic modules 13 are arranged in a substantially mirror-image streamline manner, the left module 137 and the right module 138 are prevented from shielding each other, sunlight can be fully absorbed no matter which orientation the photovoltaic modules 13 are positioned in, even if the left module 137 is positioned at the optimal sunlight receiving angle, the right module 138 can achieve the effect of approaching the optimal sunlight receiving angle, and therefore the loss of power generation amount is reduced to the maximum extent.

With combined reference to fig. 1-5, a method of installing a streamlined marine photovoltaic array mount according to one embodiment of the present invention comprises: arranging an array of pontoons at the surface, said array comprising a plurality of pontoons, preferably for example parallel rectangular pontoons 11; a plurality of parallel purlins 12 transversely penetrate the buoy 11 along two sides of the buoy, for example, the length direction of the purlins 12 is perpendicular to the length direction of the rectangular buoy 11; installing pairs of photovoltaic modules 13 along the length direction of the purlins, wherein each pair of photovoltaic modules 13 is arranged on two sides of the rectangular buoy 11, and each pair of photovoltaic modules 13 comprises a left side module 137 and a right side module 138 which are arranged in an inclined mode in a mirror image mode; connecting the first end 132 of the left side assembly 137 and the first end 132 of the right side assembly 139 to the purlin 12 at a position close to the buoy 11 through the assembly support 136, and mounting the second end 131 of the left side assembly 137 and the second end 131 of the right side assembly 138 to the purlin 12 at a position far from the buoy 11 through the assembly connecting member 134 and the assembly lower seat 135; preferably, the inclination angle of the photovoltaic module can be adjusted by designing and adjusting the height of the module support 136 and/or the module connector 134, for example, the included angle between the panel of the photovoltaic module 13 and the purlin 12 can be set to be greater than 0 degree and less than or equal to 60 degrees, preferably, the included angle is, for example, 5 to 30 degrees.

As can be understood by those skilled in the art, since the purlins 12 are arranged between the rectangular pontoons along the horizontal plane, the included angle between the panel of the photovoltaic module 13 and the purlins 12 is the inclination angle between the panel of the photovoltaic module and the water surface.

Fig. 6 is a schematic diagram showing a streamlined photovoltaic array mount on water according to another embodiment of the present invention, and fig. 7 is a schematic diagram showing a group of photovoltaic mounts among the photovoltaic array mounts shown in fig. 6. Referring to fig. 6 and 7 in combination, the streamlined photovoltaic array support on water comprises at least one pair of pontoons, preferably, for example, rectangular pontoons 11 arranged in a matrix, purlins 12 arranged in parallel between the pair of rectangular pontoons 11, and pairs of photovoltaic modules 13 arranged on the purlins 12, each pair of photovoltaic modules 13 of the pairs of photovoltaic modules 13 being substantially mirror-image and inclined, being of a streamlined design.

With combined reference to fig. 7 to 10, the rectangular pontoon 11 is for example made of a foam material as a main body, the outer surface being for example clad aluminium alloy plate. The side of the pontoon 11 is provided with through holes 111, for example, along the transverse direction, for penetrating the purlins 12. Preferably, the purlin 12 is perforated, for example transversely, on the side close to the pontoon 11, with a pin or screw 121 to be positioned with the pontoon 11 against slipping out of the latter.

Both ends of the purlin 12 are arranged through both sides of a pair of rectangular pontoons 11, wherein each pair of photovoltaic modules 13 comprises, for example, a left side module 137 and a right side module 138, the first ends 132 of which are connected together, for example, by a module support 136 and fixed, for example, in the center of the purlin 12, and the second ends 131 of which are respectively arranged, for example, in the immediate vicinity of the pair of pontoons 11. The height of the support members 136 is preferably set such that the angle between the photovoltaic module 13 panel and the purlin 12 is greater than 0 degrees and less than or equal to 60 degrees, preferably between 5 and 30 degrees.

Specifically, the second end 131 of the photovoltaic module 13 is disposed proximate the buoy 11, such as by the module lower mount 135. The lower seat 135 includes, for example, a lower seat fixing member 1351 and a lower seat support member 1352, wherein the lower seat fixing member 1351 is, for example, hooped around the outer periphery of the photovoltaic module 13, and the main body of the lower seat support member 1352 is, for example, connected to the lower seat fixing member 1351 by a connector such as a rivet or a bolt, and the side thereof is, for example, fixedly connected to the second end 131 of the photovoltaic module 13 by a connector such as a rivet or a screw. The first ends 132 of the left and

right side assemblies

137, 138 of the photovoltaic module 13 are connected together and secured, such as by a web 133, and preferably the web 133 is secured to a central portion of the purlin 12 by a support 136. The support member 136 is, for example, a V-shaped piece of metal, the bottom of which is sleeved on the center of the purlin 12, for example, by a hoop member 1361, and the top of which is connected to the first end 132 of the photovoltaic module 13, for example, by a connector such as a rivet or bolt.

With combined reference to fig. 6-10, a method of installing a streamlined marine photovoltaic array mount according to another embodiment of the present invention comprises: arranging an array of pontoons on the surface, for example comprising a plurality of juxtaposed rectangular pontoons 11; a plurality of parallel purlins 12 transversely penetrate the pontoon 11 along two sides thereof; mounting pairs of photovoltaic modules 13 along the length of the purlins, each pair of photovoltaic modules 13 for example comprising a left side module 137 and a right side module 138 which are arranged in a substantially mirror image and inclined manner; connecting a first end of the left side assembly 137 to a first end of the right side assembly 139, for example, by a connecting plate 133, the connecting plate 133 being secured to a central portion of the rectangular pontoon 11 on opposite sides of the purlin 12, for example, by a support 136; mounting a second end of the left side assembly 137 and a second end of the right side assembly 138 to the purlin 12 via the assembly lower seats 135; the included angle between the panel of the photovoltaic module 13 and the purlin 12 can be set to be greater than 0 degree and less than or equal to 60 degrees by adjusting the height of the supporting piece 136. Preferably, the included angle may be set to 5 to 30 degrees.

As will be appreciated by those skilled in the art, the angle between the panel of the photovoltaic module 13 and the purlin 12, i.e., the angle of inclination between the panel and the water surface, is due to the purlins 12 being disposed between the rectangular pontoons along the horizontal plane.

Preferably, the gap between the first ends of the left and

right side assemblies

137, 138 is adjustable, for example, by a web 133, and the angle between the face plates of the

assemblies

137, 138 and the purlin 12 can be adjusted appropriately by the web 133.

Fig. 11 is a schematic view showing a streamlined photovoltaic array support on water according to another embodiment of the present invention, and fig. 12 is a partially enlarged schematic view showing the photovoltaic array support shown in fig. 11. Referring to fig. 11 and 12 in combination, the above-water photovoltaic array support comprises at least one pair of rectangular pontoons 11, a main purline 112 crossing into the pair of rectangular pontoons, a pair of auxiliary purlines 114 installed on the main purline and arranged in parallel with the rectangular pontoons, and photovoltaic modules 13 arranged on the auxiliary purlines 114, wherein the photovoltaic modules 13 are approximately arranged in an inclined manner in a two-to-two mirror image manner, and the photovoltaic module support is designed to be a mirror image type module.

In particular, the rectangular pontoon 11 is, for example, made of a foam material as a main body, and the outer surface is, for example, clad with an aluminum alloy plate. The cross-section of the pontoon 11 is shown as rectangular, but it will be understood by those skilled in the art that the cross-section of the pontoon 11 may also be circular, oval, etc., for example. The side of the pontoon 11 is provided with through holes 111, for example, in the transverse direction, for passing main purlins 112. Although the through-holes 111 are shown as being square in shape, those skilled in the art will appreciate that the shape of the through-holes 111 may depend on the cross-section of the primary purlin 112, which may be square, circular, or other shapes, for example. Preferably, the main purlin 112 is perforated, for example transversely, near the side of the pontoon 11, with a pin or screw (not shown) to be positioned with the pontoon 11 against slipping out of the latter.

At least one pair of secondary purlins 114 is mounted, for example transversely, on the primary purlins 112 adjacent the pontoons 11 on either side. Preferably, the photovoltaic modules 13 are arranged on a pair of sub-purlins along the length direction of the rectangular pontoon 11 (i.e. the length direction of the sub-purlins 114). It will be appreciated by those skilled in the art that two or more pairs of secondary purlins 114 may be mounted laterally between a pair of rectangular pontoons 11, for example on the primary purlins 112, i.e. groups of photovoltaic modules 13 may be arranged side by side, for example along their length, between a pair of rectangular pontoons 11.

Fig. 13 is a schematic view showing the installation of a photovoltaic module of the photovoltaic array support of fig. 11, and fig. 14 is a partially enlarged schematic view showing the photovoltaic module of the photovoltaic array support of fig. 13. Referring collectively to fig. 11-14, preferably, each of the plurality of photovoltaic modules 13 disposed on the secondary purlins 114 is disposed, for example, on both sides of the primary purlins 112, wherein the low sides (also referred to as second ends) 131 of the photovoltaic modules 13 are secured, for example, by module connectors 134 to the secondary purlins 114, and the high sides (also referred to as first ends) 132 of the photovoltaic modules 13 are disposed, for example, above and adjacent to the primary purlins 112. Each set of photovoltaic modules 13 includes, for example, a left side module 137 and a right side module 138, the high sides 132 of which are secured to the secondary purlins 114, for example, by module supports 136. The support members 136 are made of T-shaped metal, for example, and are mounted at the bottom of the secondary purlin 114 near the primary purlin 112 by using connectors such as bolts or rivets, or fixed with the primary purlin 112 and the secondary purlin 114, and are connected at the top of the secondary purlin at two sides thereof with the high side 132 of each group of photovoltaic modules 13 by using connectors 1366 such as rivets or bolts.

According to a preferred embodiment of the present invention, the high side 132 of the photovoltaic module 13 may be disposed at a higher level than the low side 131 of the module, preferably such that the angle between the panel of the photovoltaic module 13 and the secondary purlin 114 is greater than 0 degrees and less than or equal to 60 degrees, preferably between 5 and 30 degrees. Those skilled in the art will appreciate that the tilt angle of the photovoltaic module can be adjusted by designing and adjusting the height of the module support 136 and/or the module connector 134. In the above arrangement, the left and

right side assemblies

137, 138 are disposed on opposite sides of the primary purlin 112, i.e., the primary purlin 112 is disposed generally midway between the left and

right side assemblies

137, 138. Those skilled in the art will appreciate that the primary purlins 112 may also be located, for example, to the left or right of the intermediate regions described above.

According to the overwater photovoltaic array bracket, the movement characteristic of natural wind can be fully adapted, the wind load borne by the whole photovoltaic array bracket is greatly reduced, and the safety and the stability of the bracket are ensured. For example, when the left side component 137 on the bracket faces the wind, it is subjected to the positive pressure generated when the natural wind passes through, and at the same time, the right side component 138 is subjected to the negative pressure generated when the natural wind passes through, but because the two components are arranged in a streamline form relative to the mirror image, the resistance to the wind movement is greatly reduced, thereby further reducing the influence of the wind load on the underwater anchoring system and ensuring the reliable operation of the photovoltaic array.

Particularly, the photovoltaic modules 13 are arranged in an inclined manner in a two-to-two mirror image manner, the left module 137 and the right module 138 are prevented from being shielded from each other, sunlight can be fully absorbed no matter which orientation the photovoltaic modules 13 are positioned in, even if the left module 137 is positioned at the optimal sunlight receiving angle, the right module 138 can achieve the effect of approaching the optimal receiving, and therefore the loss of power generation amount is reduced to the maximum extent.

In summary, the inclination angle between the panel of the photovoltaic module 13 and the water surface may be set according to the actual environment of the construction project of the photovoltaic array in a specific water area, such as the illumination condition and the longitude and latitude of the place where the project is located. For example, the coordinates of the project are north latitude N1 ° 16 'east longitude E103 ° 50', altitude 6 m, and the annual generation hours are 1551.9 hours when the conventional unidirectional photovoltaic module shown in fig. 11 is arranged towards south, for example, the inclination angle is 5 degrees; with the streamlined waterborne photovoltaic array mount according to the present application, the annual generation hours is 1561.5 hours when the pair of photovoltaic modules are arranged north and south, for example at an angle of 5 degrees. Preferably, with a streamlined marine photovoltaic array mount according to the present application, the annual generation hours is 1562.9 hours when the pair of photovoltaic modules are arranged east to west, for example at an inclination of 5 degrees.

According to the streamline waterborne photovoltaic array bracket, the left side component 137 and the right side component 138 of the paired photovoltaic components 13 are arranged in an inclined mirror symmetry mode approximately, so that the problem that one side component shields the other side component to receive sunlight is solved, the gap between the adjacent photovoltaic components 13 can be greatly reduced, namely, the gap generated by the shielding problem is fully utilized, the density of the photovoltaic components 13 can be greatly improved, the utilization rate of the water area is improved, and the capacity is increased. Moreover, the streamlined overwater photovoltaic array support has the advantages that the daylighting adaptability of the photovoltaic module is extremely strong, and the inclination angle of the photovoltaic module can be changed as required, so that the constraint that the orientation of the photovoltaic module in the prior art is fixed is overcome, the 360-degree omnibearing orientation design can be flexibly carried out according to a specific water area environment and a field, and the installation and maintenance of a photovoltaic array are greatly facilitated.

In a preferred embodiment, the angle of inclination between the respective panels of the left 137 and right 138 photovoltaic modules and the purlin 12 may be the same or different, but still be substantially a mirror image. For example, when the construction project is near the equator or in low latitude areas, the inclination angles of the left side module and the right side module may be set to be the same, and when the project is in high latitude areas, in order to avoid the occurrence of the shading of the modules, the inclination angle of the module on the side facing away from the sunlight may be set to be smaller than the inclination angle of the module on the side facing the sunlight to increase the power generation amount thereof. In a word, according to the streamline waterborne photovoltaic array bracket, the inclination angles of the paired photovoltaic components can be flexibly adjusted according to the specific conditions of an installation site, including geographic positions, water area environments, sunlight irradiation, wind direction and wind power and other factors.

While the present application has been described above in terms of preferred embodiments, those of ordinary skill in the art, in light of the above teachings, may make numerous modifications to the apparatus described in this application without departing from the concept, spirit and scope of the application. Further, modifications may be made to the apparatus disclosed herein and the same or similar results achieved. All such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the spirit, scope and concept of the application as defined by the appended claims.
