[0040] In this embodiment, the gasket 3 is quickly pre-installed in the first fixing hole 10 of the photovoltaic system through the clamping piece 31, so that the opening 210 of the sleeve 2 is coaxially adapted to the first fixing hole 10 of the frame 1, which facilitates the second fastening component 4 and the first fastening component 22 in the sleeve 2 to be quickly installed and fixed, and the installation process is simple, which reduces the matching time between the first fastening component 22 and the first fixing hole 10 and improves the installation efficiency.

[0041] Specifically, refer to Figure 2, the ferrule 2 covers the opening 210 of the ferrule 2 through the gasket 3 so that the first fastening component 22 is preset in the placement cavity 20 of the ferrule 2, and the ferrule 2 and the gasket 3 are fixedly connected by means of gluing, welding, clamping, etc., which are not further limited in this application. For example, a first fixing hole 10 is provided on the frame 1 of the photovoltaic module. The second fixing hole 30 is coaxially adapted with the opening 210 and coaxially adapted with the first fixing hole 10 on the frame 1. At the same time, when the second fixing hole 30 of the gasket 3 is pre-installed with the first fixing hole 10 of the frame 1, the gasket 3 can also be fixed to the frame 1 by means of gluing, welding, clamping, etc. Among them, the gasket 3 not only plays the role of fixing the first fastening component 22 to the placement cavity 20, but also increases the contact area between the first fastening component 22 and the frame 1, so that the locking force of the first fastening component 22 is evenly distributed, protecting the first fastening component 22 and the frame 1, and preventing the first fastening component 22 from falling. A pair of clamping members 31 are symmetrically arranged at both ends of the second fixing hole 30, and one end of the pair of clamping members 31 away from the gasket 3 is suitable for abutting against the inner side wall of the first fixing hole 10, so that the gasket 3 is preset at the first fixing hole 10. This clamping member 31 is located at the end of the gasket 3 away from the ferrule 2, so that the first fixing hole 10 and the second fixing hole 30 are coaxially adapted, and the second fastening component 4 is suitable for passing through the first fixing hole 10 and the second fixing hole 30. It is worth noting that in another embodiment, the gasket 3 can also abut against the outer side wall of the frame 1. Specifically, one end of the gasket 3 is provided with a mounting groove, and the frame 1 is suitable for abutting and fixing in the mounting groove. When the side wall of the frame 1 abuts against the bottom of the mounting groove, the first fixing hole 10 matches the second fixing hole 30. At the same time, the gasket 3 can also be fixedly connected to the frame 1, so that the first fastening component 22 on the ferrule 2 is preset above the first fixing hole 10, which is convenient for the subsequent installation, and the second fastening component 4 is directly connected to the first fastening component 22 through the frame 1.

[0042] Further, refer to Figure 6 The clamping member 31 includes an arc portion 311 and an extension portion 312. The arc portion 311 connects the extension portion and the inner wall of the second fixing hole 30. The gasket 3 has a first direction 300. The arc portion 311 extends along the first direction 300 toward a side away from the ferrule 2. The end of the arc portion 311 is perpendicular to the gasket 3, and the extension portion extends from the end of the arc portion 311 toward a side away from the ferrule 2.

[0043] In this embodiment, the extension portion 312 extends into the first fixing hole 10 and abuts against the inner wall of the first fixing hole 10, the arc portion 311 connects the extension portion 312 and the inner wall of the second fixing hole 30, the top of the arc portion 311 is arc-shaped, and the first fastening component 22 is suitable for being squeezed and abutted against the arc portion 311, thereby increasing the locking force of the first fastening component 22.

[0044] Specifically, when the first fastening component 22 and the second fastening component 4 are locked and installed, the first washer 222 abuts against the top of the arc portion 311. At this time, the arc portion 311 is in an arc shape, and the arc portion 311 can effectively limit the downward force of the first fastening component 22, so that the first fastening component 22 is fixed in the placement cavity 20 to prevent the first fastening component 22 from falling out of the placement cavity 20. In more detail, the gasket 3 is a rectangular parallelepiped, the second fixing hole 30 is also a rectangle, the first direction 300 is the length direction of the gasket 3, the arc portion 311 extends from the connection with the gasket 3 to the thickness direction of the gasket 3, and the extension portion extends along the thickness direction of the gasket 3 to the first fixing hole 10.

[0045] In a modified embodiment, the clamping member also includes a fixing portion, which is arranged at an end of the extension portion 312 away from the arc portion 311. After installation, the fixing portion is suitable for passing through the first fixing hole 10 and abutting against the bottom wall of the frame 1, so that the gasket 3 is fixedly installed on the frame 1.

[0046] Furthermore, an abutting portion 23 is provided on the ferrule 2 , a pair of the abutting portions 23 are symmetrically arranged at the bottom of the ferrule 2 and an abutting groove 230 is formed between the pair of abutting portions 23 , and both ends of the gasket 3 are abutted and installed in the abutting groove 230 .

[0047] In this embodiment, an abutment groove 230 is also provided at the bottom of the ferrule 2, and the gasket 3 is suitable for abutting and installing in the abutment groove 230, so that the gasket 3 and the ferrule 2 are locked and fixed, thereby preventing the gasket 3 from rotating and affecting the installation performance of the installation kit; at the same time, the opening 210 and the second fixing hole 30 are coaxially adapted faster and more quickly.

[0048] Specifically, a pair of abutment portions 23 are respectively arranged at the two ends of the bottom of the ferrule 2 and are relatively located at the two ends of the width direction of the gasket 3, and the two ends of the length direction of the gasket 3 extend out of the abutment groove 230. The outer wall of the gasket 3 abuts against the groove wall of the abutment groove 230 to prevent the gasket 3 from moving and affecting the locking performance of the first fastening component 22 and the second fastening component 4. Moreover, when installing the gasket 3 and the ferrule 2, it is only necessary to place the gasket 3 in the abutment groove 230 to complete the positioning of the opening 210 and the second fixing hole 30, and the installation is simple and convenient. In this embodiment, the width of the gasket 3 is smaller than the diameter of the ferrule 2, and the length of the gasket 3 is greater than the diameter of the ferrule 2. When the gasket 3 is abutted and fixed with the ferrule 2, the two ends of the gasket 3 in the width direction abut against the groove wall of the abutment groove 230, and the two ends of the gasket 3 in the length direction are relatively located outside the ferrule 2. In a modified embodiment, the abutment groove 230 can also match the outer wall of the gasket 3, that is, the gasket 3 is completely installed inside the ferrule 2. At the same time, the clamping member 31 provided in the second fixing hole 30 extends into the first fixing hole 10 along the inner side wall of the second fixing hole 30, and a pair of clamping members 31 are symmetrically arranged at both ends of the second fixing hole 30 and are suitable for abutting against the inner side walls of the first fixing hole 10 on both radial sides. Preferably, an arc groove is further provided on the side wall of the abutting portion 23, and the arc groove is relatively located in the middle of the side wall of the abutting groove 230. The arc groove is used to reserve deformation space for the gasket 3, prevent the gasket 3 and the ferrule 2 from being over-extruded, causing damage to the gasket 3 and the ferrule 2, and increase their durability.

[0049] Further, refer to Figure 5 The inner wall of the placement cavity 20 matches the outer wall of the first fastening component 22 , and a third fixing hole 211 is further provided at one end of the ferrule 2 away from the opening 210 , and the third fixing hole 211 is coaxially adapted to the opening 210 .

[0050] In this embodiment, the inner wall of the placement cavity 20 matches the outer wall of the nut 221, which can effectively prevent the first fastening component 22 from idling; the third fixing hole 211 reserves space for tightening the second fastening component 4, preventing the second fastening component 4 from abutting against the ferrule 2, resulting in the second fastening component 4 failing to reach the optimal locking position, thereby causing the locking performance of the installation kit to be poor.

[0051] Specifically, for example, the nut 221 is a hexagonal nut, and the inner wall of the placement cavity 20 is a hexagon, so that the nut 221 is fixedly arranged in the placement cavity 20 to prevent the nut 221 from idling. It is worth noting that the present embodiment does not further limit the structure of the nut 221. As long as the first fastening component 22 is preset in the placement cavity 20, the first fastening component 22 can play a fastening role, which is within the protection scope of the present application. The third fixing hole 211 is provided in the ferrule 2, and the third fixing hole 211 matches the opening 210, the second fixing hole 30, and the first fixing hole 10, so as to facilitate the passage of the second fastening component 4.

[0052] Further, refer to Figure 4 and Figure 7 The present application provides a photovoltaic system, including a frame 1 of a photovoltaic component, a fixing structure 5 of the photovoltaic component and an installation kit of any one of the above-mentioned preferred embodiments, wherein a first fixing hole 10 is provided on the frame 1, and a gasket 3 of the installation kit is pre-engaged on the frame 1 so that a second fixing hole 30 of the gasket 3 is coaxially adapted to the first fixing hole 10.

[0053] Specifically, the frame 1 is a supporting structure of the photovoltaic module, and the fixed structure 5 is a purlin fixedly connected to the photovoltaic module. An installation kit of the present application can fix the frame of the photovoltaic module to the purlin. Of course, the frame 1 and the fixed structure 5 are only applicable examples, and the installation kit of the present application can also be used for other fixed connection structures of the photovoltaic system that require bolts, nuts, and washers. In this embodiment, the first fixing hole 10 is oval. However, the specific shape of the first fixing hole 10 on the frame 1 is not further limited in this application, and it can also be square, circular, and other shapes. At the same time, the ferrule 2 with the first fastening component 22 is preset on the structure to be fixed through the gasket 3, which also facilitates the tightening of the subsequent automatic installation robot and increases the degree of automation of the photovoltaic industry assembly. This installation kit can be pre-installed at the factory or automatically placed by the automatic installation robot on site. During installation, the installation kit is pre-assembled on the four first fixing holes 10 of the frame 1, and then the frame 1 is placed on other required components by the handling robot, and then the fastening robot automatically finds the position of the first fixing hole 10 under the required component and inserts the second fastening component 4 upward.

[0054] Furthermore, it also includes a first fastening component 22 and a second fastening component 4, the first fastening component 22 is suitable for being placed in the placement cavity 20 of the ferrule 2 through the opening 210 of the ferrule 2; the fixing structure 5 of the photovoltaic component includes a fourth fixing hole 51, and the fourth fixing hole 51 can be coaxially adapted to the first fixing hole 10 and the second fixing hole 30; the second fastening component 4 is suitable for connecting the first fastening component 22 through the fourth fixing hole 51, the first fixing hole 10 and the second fixing hole 30, so that the frame 1 of the photovoltaic component is fixedly connected to the fixing structure 5 of the photovoltaic component. In this embodiment, the first fastening component 22 is fixed in the placement cavity 20 of the ferrule 2 through the gasket 3, so that the first fastening component 22 is not easy to fall off, and the second fixing hole 30 of the gasket 3 is coaxially adapted to the first fixing hole 10 of the frame 1, so that the first fastening component 22 and the first fixing hole 10 can be coaxially adapted more quickly and accurately, and the second fastening component 4 is convenient to connect to the first fastening component 22 after passing through the fourth fixing hole 51, the first fixing hole 10 and the second fixing hole 30. The installation process is simple and efficient.

[0055] Specifically, a placement cavity 20 is provided inside the ferrule 2, and the placement cavity 20 is suitable for placing the first fastening component 22. An opening 210 connected to the placement cavity 20 is provided at one end of the ferrule 2, and the first fastening component 22 is suitable for being placed in the placement cavity 20 through the opening 210; a gasket 3 is arranged at the opening 210 of the ferrule 2 and fixes the first fastening component 22 in the placement cavity 20, and a second fixing hole 30 is provided on the gasket 3, and the second fixing hole 30 is coaxially adapted to the first fixing hole 10 on the frame 1; the second fastening component 4 is suitable for connecting the first fastening component 22 after passing through the first fixing hole 10 and the second fixing hole 30. The first fastening assembly 22 includes a nut 221 and a first washer 222. The nut 221 is disposed at one end of the placement cavity 20 away from the opening 210. The first washer 222 is disposed between the nut 221 and the gasket 3. The first washer 222 is disposed between the nut and the gasket 3 to increase the friction between the nut 221 and the second fastening assembly 4, prevent the nut 221 from loosening and falling, and increase the installation strength of the installation kit. The first washer 222 is an elastic washer. The spring washer can provide a force to the nut 221 after the nut 221 is tightened, increase the friction between the nut 221 and the second fastening assembly 4, and prevent the second fastening assembly 4 and the nut 221 from loosening. At the same time, the elastic washer can also provide the necessary flexibility and elasticity, apply axial pressure when compressed, and generate a spring-like force, thereby absorbing and distributing the load so that they can maintain elasticity and prevent bending or flattening under load. It is worth noting that the first washer 222 includes but is not limited to an elastic washer, and the deformed washer structure of the elastic washer is easy to think of by a person skilled in the art, and this application will not be further elaborated. In a modified embodiment, the first fastening assembly 22 includes a top nut, and the top nut includes a first nut and a second nut, and the thread directions of the first nut and the second nut are opposite and the size and pitch of the first nut and the second nut are the same. In this embodiment, the top nut can effectively prevent the nut from loosening. The principle is that the first nut and the second nut have opposite thread directions, but the size and pitch of the thread are the same. When the first nut and the second nut are tightened, the friction between the first nut and the second nut will cause them to squeeze each other, thereby increasing the tightening force. At the same time, since the thread directions of the first nut and the second nut are opposite, their loosening directions are also opposite, so that the nut can be effectively prevented from loosening. At the same time, the first fastening assembly 22 may also include other deformed anti-loosening nuts such as self-locking nuts, and this application will not be further elaborated.

[0056] The second fastening assembly 4 includes a bolt 41 and a second washer 42. The bolt 41 passes through the fourth fixing hole 51, the first fixing hole 10, the second fixing hole 30 and the opening 210 and then connects to the first fastening assembly 22. The second washer 42 is sleeved on the bolt 41 and is relatively located between the bottom side wall of the frame 1 and the bolt 41. The second washer 42 abuts against the bottom wall of the abutment portion 23 and the bottom wall of the frame 1. The second washer 42 includes a flat washer, which can evenly distribute the pressure of the bolt 41 to the frame 1 to protect the second fastening assembly 4 and the surface of the frame 1. It is worth noting that the second fastening assembly 4 includes but is not limited to the bolt 41, and can also be other fasteners such as screws, which is easy for those skilled in the art to think of, and this application will not be further elaborated. The second washer 42 can also be other deformable washers such as double-stacked self-locking washers, and other deformable washers such as double-stacked self-locking washers can also be arranged inside the ferrule 2.

[0057] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
