[0043] Example

[0044] Please also read Figure 1 and Figure 2 This embodiment provides a connection mechanism 10 for connecting adjacent large floating tube units 20 in an inland large floating tube floating photovoltaic system. The connection mechanism 10 includes a first connection seat 100, a second connection seat 200 and a connection shaft 300.

[0045] The first connection seat 100 is used to connect with one of the large floating tube units 20 , and the second connection seat 200 is used to connect with another adjacent large floating tube unit 20 .

[0046] In addition, the connecting shaft 300 is respectively connected to the first connecting seat 100 and the second connecting seat 200, and the connecting shaft 300 is rotationally matched with the first connecting seat 100 and / or the second connecting seat 200, and the connecting shaft 300 is slidingly matched with the first connecting seat 100 and / or the second connecting seat 200 along its own axial direction.

[0047] When the connection mechanism 10 is used, the first connection seat 100 is connected to one of the large floating tube units 20, and the second connection seat 200 is connected to another adjacent large floating tube unit 20. On this basis, the first connection seat 100 and the second connection seat 200 are connected through the connection shaft 300, and the connection shaft 300 is rotatably matched with the first connection seat 100 and / or the second connection seat 200, and at the same time, it is slidably matched with the first connection seat 100 and / or the second connection seat 200 along its own axial direction, so that the adjacent large floating tube units 20 can not only rotate relatively around the connection shaft 300, but also slide relatively along the axial direction of the connection shaft 300, thereby realizing the movable connection between the adjacent large floating tube units 20.

[0048] When some of the large floating tube units 20 rise and fall and shake with the water surface, other large floating tube units 20 may not move along, thereby reducing the force on the connecting mechanism 10, making the connecting mechanism 10 less prone to damage and having a longer service life.

[0049] In some embodiments, the connecting shaft 300 is fixedly disposed on the second connecting seat 200. The connecting shaft 300 is rotationally matched with the first connecting seat 100, and is slidingly matched with the first connecting seat 100 along its own axial direction.

[0050] Furthermore, a first self-lubricating sleeve 110 is disposed on the first connecting seat 100. The connecting shaft 300 is inserted into the first self-lubricating sleeve 110 and is rotationally and slidably matched with the first self-lubricating sleeve 110.

[0051] When in use, the first self-lubricating sleeve 110 can reduce the rotational friction and sliding friction between the connecting shaft 300 and the first connecting seat 100, so that the adjacent large floating tube units 20 can rotate and slide relative to each other more flexibly.

[0052] In other embodiments, the connecting shaft 300 is fixedly disposed on the first connecting seat 100. The connecting shaft 300 is rotationally matched with the second connecting seat 200, and is slidingly matched with the second connecting seat 200 along its own axial direction.

[0053] Furthermore, a second self-lubricating sleeve 210 is disposed on the second connecting seat 200. The connecting shaft 300 is inserted into the second self-lubricating sleeve 210 and is rotationally and slidably matched with the second self-lubricating sleeve 210.

[0054] When in use, the second self-lubricating sleeve 210 can reduce the rotational friction and sliding friction between the connecting shaft 300 and the second connecting seat 200, so that the adjacent large floating tube units 20 can rotate and slide relative to each other more flexibly.

[0055] In some other embodiments, the connecting shaft 300 is rotationally matched with the first connecting seat 100 and the second connecting seat 200 respectively, and is slidingly matched with the first connecting seat 100 and the second connecting seat 200 respectively along its own axial direction.

[0056] Further, the first connection seat 100 is provided with a first self-lubricating sleeve 110, and the second connection seat 200 is provided with a second self-lubricating sleeve 210. Accordingly, the connecting shaft 300 is simultaneously inserted into the first self-lubricating sleeve 110 and the second self-lubricating sleeve 210, and is respectively rotationally matched and slidably matched with the first self-lubricating sleeve 110 and the second self-lubricating sleeve 210.

[0057] Specifically, the first connection seat 100 includes a first seat body 120 and a first ear plate 130. The first seat body 120 is used to connect with one of the large floating tube units 20, and the first ear plate 130 is connected to the first seat body 120, and the first ear plate 130 is perpendicular to the axis direction of the connecting shaft 300.

[0058] Similarly, the second connection seat 200 includes a second seat body 220 and a second ear plate 230. The second seat body 220 is used to connect with another adjacent large floating tube unit 20, and the second ear plate 230 is connected to the second seat body 220, and the second ear plate 230 is perpendicular to the axis direction of the connection shaft 300.

[0059] The connecting shaft 300 is connected to the first ear plate 130 and the second ear plate 230 respectively, and the connecting shaft 300 is rotationally matched with the first ear plate 130 and / or the second ear plate 230, and the connecting shaft 300 is slidingly matched with the first ear plate 130 and / or the second ear plate 230 along its own axial direction.

[0060] For example, the first lug plate 130 is provided with a first self-lubricating sleeve 110, and the second lug plate 230 is provided with a second self-lubricating sleeve 210. The connecting shaft 300 is rotationally and slidably matched with the first lug plate 130 through the first self-lubricating sleeve 110, and then rotationally and slidably matched with the entire first connecting seat 100. At the same time, the connecting shaft 300 is rotationally and slidably matched with the second lug plate 230 through the second self-lubricating sleeve 210, and then rotationally and slidably matched with the entire second connecting seat 200.

[0061] Furthermore, at least two first ear plates 130 are provided, and the at least two first ear plates 130 are arranged along the axial direction of the connecting shaft 300 , and the second ear plate 230 is located between two adjacent first ear plates 130 .

[0062] When adjacent large floating tube units 20 slide relatively along the axial direction of the connecting shaft 300, the sliding range of the second ear plate 230 is limited by the first ear plate 130, thereby limiting the relative sliding range of the adjacent large floating tube units 20, so that the entire inland large floating tube floating photovoltaic system remains relatively stable.

[0063] In some embodiments, three first ear plates 130 are provided, two second ear plates 230 are provided, and the three first ear plates 130 and the two second ear plates 230 are alternately arranged along the axial direction of the connecting shaft 300 .

[0064] At this time, there is a second ear plate 230 between every two adjacent first ear plates 130. The connecting shaft 300 is connected to the first seat body 120 through three first ear plates 130, and then connected to one of the large floating tube units 20, so that the force is more uniform. At the same time, the connecting shaft 300 is connected to the second seat body 220 through two second ear plates 230, and then connected to another adjacent large floating tube unit 20, so that the force is more uniform.

[0065] See also Figure 3 In some embodiments, the first seat body 120 adopts a first connecting plate 121. The first connecting plate 121 is parallel to the axial direction of the connecting shaft 300, and a plurality of first mounting holes 122 are arranged on the first connecting plate 121, and the plurality of first mounting holes 122 are evenly distributed around the first direction.

[0066] The first direction is perpendicular to the first connecting plate 121 , and is indicated by the X1 direction in the figure.

[0067] Exemplarily, the first connecting plate 121 is connected to one of the large floating tube units 20 by a plurality of bolts. The bolts correspond to the first mounting holes 122 one by one and pass through the corresponding first mounting holes 122, so as to achieve a stable connection between the first connecting plate 121 and the large floating tube unit 20.

[0068] See also Figure 4 Similarly, the second seat body 220 adopts a second connecting plate 221. The second connecting plate 221 is parallel to the axial direction of the connecting shaft 300, and a plurality of second mounting holes 222 are arranged on the second connecting plate 221, and the plurality of second mounting holes 222 are evenly distributed around the second direction.

[0069] The second direction is perpendicular to the second connecting plate 221 , and is indicated by the X2 direction in the figure.

[0070] Exemplarily, the second connecting plate 221 is connected to another adjacent large floating tube unit 20 by a plurality of bolts. The bolts correspond to the second mounting holes 222 one by one and pass through the corresponding second mounting holes 222, so as to realize a stable connection between the second connecting plate 221 and the large floating tube unit 20.

[0071] It can be understood that when the water surface is calm, the first direction is parallel to or coincides with the second direction. When the adjacent large floating tube units 20 rotate relative to each other, the first direction is obliquely intersected with the second direction.

[0072] Please refer again Figure 2 Furthermore, a first limit member 310 is provided at one end of the connecting shaft 300 along its own axial direction, a second limit member 320 is provided at the other end of the connecting shaft 300 along its own axial direction, and the first connecting seat 100 and the second connecting seat 200 are located between the first limit member 310 and the second limit member 320.

[0073] When the connecting shaft 300 slides relative to the first connecting seat 100 and / or the second connecting seat 200 along its own axial direction, the first limit member 310 and the second limit member 320 can limit the sliding range of the connecting shaft 300 relative to the first connecting seat 100 and / or the second connecting seat 200, thereby preventing the connecting shaft 300 from detaching from the first connecting seat 100 and / or the second connecting seat 200.

[0074] Exemplarily, the first connecting seat 100 and the second connecting group are connected by bolts, the rod of the bolt serves as the connecting shaft 300 , the head of the bolt serves as the first limiting member 310 , and the nut sleeved on the bolt serves as the second limiting member 320 .

[0075] In summary, the above-mentioned connecting mechanism 10 is used to flexibly connect adjacent large floating tube units 20. When some large floating tube units 20 rise and fall and shake with the water surface, other large floating tube units 20 may not move with them, thereby reducing the force on the connecting mechanism 10. The connecting mechanism 10 is not easily damaged and has a longer service life.

[0076] 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 connecting mechanism 10.

[0077] The first connection seat 100 is connected to one of the large floating tube units 20 , and the second connection seat 200 is connected to another adjacent large floating tube unit 20 , thereby movably connecting the adjacent large floating tube units 20 .

[0078] Adjacent large floating tube units 20 can not only rotate relative to each other around the connecting shaft 300, but also slide relative to each other along the axis direction of the connecting shaft 300. When some large floating tube units 20 rise and fall and shake with the water surface, other large floating tube units 20 may not move with them, thus reducing the force on the connecting mechanism 10, making the connecting mechanism 10 less prone to damage and having a longer service life.

[0079] In some embodiments, the large floating tube unit 20 includes a floating tube body 21, and the floating tube body 21 is arranged along a third direction, which is indicated by the Y direction in the figure.

[0080] In addition, two ends of the floating tube body 21 along the third direction are respectively connected to the connection mechanisms 10 , and at least two connection mechanisms 10 are connected to the side surface of the floating tube body 21 .

[0081] Correspondingly, the inland large floating tube floating photovoltaic system comprises a plurality of large floating tube units 20, and the plurality of large floating tube units 20 are arranged in a matrix.

[0082] In the third direction, two adjacent large floating tube units 20 are connected by the connection mechanism 10 at the end of the floating tube body 21. In the horizontal direction perpendicular to the third direction, two adjacent large floating tube units 20 are connected by the connection mechanism 10 at the side of the floating tube body 21.

[0083] 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.

[0084] 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.

[0085] 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.
