[0039] Example

[0040] Please also read Figure 1 and Figure 2This embodiment provides a connection assembly 10 for connecting adjacent large floating tube units 20 in an inland large floating tube floating photovoltaic system. The connection assembly 10 includes a mounting seat 100, at least one flexible connector 200 and at least one elastic member 300.

[0041] The mounting seat 100 at least includes a first mounting seat 101 and a second mounting seat 102. The first mounting seat 101 is used to connect with one of the large floating tube units 20, and the second mounting seat 102 is used to connect with another adjacent large floating tube unit 20.

[0042] Correspondingly, one end of at least one flexible connector 200 is connected to the first mounting seat 101 , and the other end is connected to the second mounting seat 102 .

[0043] In addition, at least one elastic member 300 is located between the first mounting seat 101 and the second mounting seat 102 .

[0044] When the connection assembly 10 is used, the first mounting seat 101 is connected to one of the large floating tube units 20, and the second mounting seat 102 is connected to another adjacent large floating tube unit 20. On this basis, the first mounting seat 101 and the second mounting seat 102 are connected by a flexible connector 200, thereby realizing a flexible connection between adjacent large floating tube units 20.

[0045] When adjacent large floating tube units 20 are impacted by wind and waves and move away from each other, the flexible connector 200 is stretched straight to keep the adjacent large floating tube units 20 connected, thus connecting the large floating tube units 20 in the entire inland large floating tube floating photovoltaic system into one.

[0046] When the adjacent large floating tube units 20 are impacted by wind and waves and approach each other, the flexible connector 200 bends until the first mounting seat 101 and the second mounting seat 102 are supported against each other by the elastic member 300 located between the first mounting seat 101 and the second mounting seat 102. At this time, the elastic member 300 can mitigate the impact and effectively protect the large floating tube unit 20.

[0047] Under the long-term impact of wind and waves, the flexible connector 200 is repeatedly bent and straightened, is not easily damaged by fatigue, and has a longer service life.

[0048] In some embodiments, the mounting base 100 includes a first mounting base 101 and a second mounting base 102. At this time, the connection assembly 10 is used to connect two adjacent large floating tube units 20. For any two adjacent large floating tube units 20 in the inland large floating tube floating photovoltaic system, they are connected by the connection assembly 10.

[0049] In other embodiments, the mounting base 100 includes a first mounting base 101, a second mounting base 102, a third mounting base 100 (not shown in the figure) and a fourth mounting base 100 (not shown in the figure). The first mounting base 101 and the second mounting base 102, the second mounting base 102 and the third mounting base 100, the third mounting base 100 and the fourth mounting base 100 are all connected by a flexible connector 200. Elastic members 300 are arranged between the first mounting base 101 and the second mounting base 102, between the second mounting base 102 and the third mounting base 100, between the third mounting base 100 and the fourth mounting base 100, and between the fourth mounting base 100 and the first mounting base 101. Accordingly, the large floating tube units 20 constituting the inland large floating tube floating photovoltaic system are arranged in a matrix, and the connecting assembly 10 is used to connect four adjacent large floating tube units 20.

[0050] See also Figure 3 In some embodiments, the mounting seat 100 includes a first mounting portion 110 and a second mounting portion 120 connected to each other. The first mounting portion 110 is used to connect with the large floating tube unit 20, and the second mounting portion 120 is connected with the flexible connector 200.

[0051] During assembly and disassembly, the flexible connector 200 and the large floating tube unit 20 do not interfere with each other, which facilitates operation.

[0052] Furthermore, the second mounting portion 120 is composed of a panel 121 and a side panel 122 .

[0053] The panel 121 is disposed perpendicular to the first direction, is connected to the flexible connector 200 , and has a supporting surface facing the elastic member 300 .

[0054] The side plate 122 is arranged parallel to the first direction, one end of the side plate 122 along the first direction is connected to the panel 121 , and the other end of the side plate 122 along the first direction is connected to the first mounting portion 110 .

[0055] The first direction is the direction of a line connecting two adjacent mounting seats 100 , which is indicated by the X direction in the figure.

[0056] It can be understood that when the flexible connector 200 is stretched straight, the flexible connector 200 extends along the first direction.

[0057] When the adjacent large floating tube units 20 are impacted by wind and waves and approach each other, the panel 121 of the first mounting seat 101 and the panel 121 of the second mounting seat 102 are mutually abutted by the elastic member 300, and the elastic member 300 contacts the abutting surface of the panel 121. Since there is a sufficiently large contact area between the elastic member 300 and the panel 121, the force applied to the elastic member 300 is more dispersed, and the elastic member 300 is not easily damaged.

[0058] Specifically, the second mounting portion 120 is composed of a panel 121 and two side panels 122. Meanwhile, two first mounting portions 110 are provided, respectively connected to one end of the two side panels 122 away from the panel 121 along the first direction.

[0059] When adjacent large floating tube units 20 are impacted by wind and waves and move away from each other, the tension on the flexible connector 200 acts on the panel 121, then is transmitted to the two first mounting portions 110 through the two side panels 122, and finally acts evenly on the large floating tube units 20.

[0060] In some embodiments, the first mounting base 101 and the second mounting base 102 are connected via a flexible connector 200 .

[0061] In other embodiments, the first mounting seat 101 and the second mounting seat 102 may also be connected by two, three or more flexible connectors 200. When adjacent large floating tube units 20 are impacted by wind and waves and move away from each other, more flexible connectors 200 can withstand greater tension, thereby ensuring the connection stability between adjacent large floating tube units 20.

[0062] Specifically, the flexible connector 200 is made of steel strands, which can withstand a large tensile force. When the adjacent large floating tube units 20 are impacted by wind and waves and approach each other, the steel strands bend and can provide a certain elastic force, thereby playing a better buffering role.

[0063] In addition, both ends of the steel strand are respectively covered with aluminum sleeves 210. One of the aluminum sleeves 210 is supported on the side of the first mounting seat 101 facing away from the second mounting seat 102, and the other aluminum sleeve 210 is supported on the side of the second mounting seat 102 facing away from the first mounting seat 101.

[0064] In some embodiments, the flexible connector 200 passes through the elastic member 300 , and the flexible connector 200 is connected to the elastic member 300 .

[0065] After assembly, the flexible connector 200 limits the elastic member 300 so that the elastic member 300 is always located between the first mounting seat 101 and the second mounting seat 102, ensuring that the first mounting seat 101 and the second mounting seat 102 are supported against each other by the elastic member 300 when they are close to each other.

[0066] Furthermore, two elastic members 300 are provided, and the two elastic members 300 are arranged on the flexible connecting member 200 at an interval.

[0067] When adjacent large floating tube units 20 are impacted by wind and waves and approach each other, elastic collisions occur between the first mounting seat 101 and one of the elastic members 300, between the second mounting seat 102 and another elastic member 300, and between the two elastic members 300, resulting in a better buffering effect.

[0068] In other embodiments, the elastic member 300 is disposed on the side of the first mounting seat 101 facing the second mounting seat 102 and remains relatively fixed to the first mounting seat 101, ensuring that the first mounting seat 101 is always supported against the second mounting seat 102 through the elastic member 300 when adjacent large floating tube units 20 approach each other.

[0069] Alternatively, the elastic member 300 is disposed on a side of the second mounting seat 102 facing the first mounting seat 101 and remains relatively fixed to the second mounting seat 102 .

[0070] Alternatively, the elastic members 300 are arranged in pairs, wherein one elastic member 300 is arranged on a side of the first mounting seat 101 facing the second mounting seat 102 , and the other elastic member 300 is arranged on a side of the second mounting seat 102 facing the first mounting seat 101 .

[0071] Specifically, the elastic member 300 is an elastic pad, which may be made of rubber, polyurethane or the like, has a larger force-bearing surface, and can disperse the pressure.

[0072] In summary, the adjacent large floating tube units 20 are flexibly connected using the above-mentioned connection assembly 10. Under the long-term impact of wind and waves, the flexible connection member 200 is repeatedly bent and straightened, is not easily damaged by fatigue, and has a longer service life.

[0073] See also Figure 1 This embodiment also provides an inland large floating tube floating photovoltaic system, including at least two large floating tube units 20 and the above-mentioned connection assembly 10.

[0074] The first mounting seat 101 is connected to one of the large floating tube units 20 , and the second mounting seat 102 is connected to another adjacent large floating tube unit 20 , thereby flexibly connecting the adjacent large floating tube units 20 .

[0075] The number of the large floating tube units 20 can be two or more. When the number of the large floating tube units 20 is more than two, any two adjacent large floating tube units 20 are flexibly connected through a connecting assembly 10 .

[0076] When the adjacent large floating tube units 20 are impacted by wind and waves and move away from each other, the flexible connector 200 is stretched straight to keep the adjacent large floating tube units 20 connected, connecting the large floating tube units 20 in the entire inland large floating tube floating photovoltaic system. When the adjacent large floating tube units 20 are impacted by wind and waves and move closer to each other, the flexible connector 200 bends until the first mounting seat 101 and the second mounting seat 102 are mutually supported by the elastic member 300 located between the first mounting seat 101 and the second mounting seat 102.

[0077] Please combine Figure 2 In some embodiments, the large floating tube unit 20 includes a bracket 21. Accordingly, the mounting seat 100 is bolted to the bracket 21, and an adjustment slot 111 is provided on the first mounting portion 110 of the mounting seat 100 for allowing the bolt to pass through.

[0078] One end of the bolt is fixed on the bracket 21, and the other end of the bolt passes through the adjustment slot 111 and is sleeved with a nut. The mounting seat 100 and the bracket 21 can be fixed by tightening the nut.

[0079] Exemplarily, the adjustment groove 111 is a waist-shaped groove. When the mounting base 100 is moved relative to the bracket 21 along the length direction of the adjustment groove 111, the position of the bolt in the adjustment groove 111 changes. Therefore, after loosening the nut, the relative position of the mounting base 100 and the bracket 21 can be adjusted, and then the nut can be tightened again to fix it.

[0080] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0081] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0082] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
