Description

Technical Field

[0001] This application relates to the field of new energy technology, specifically to photovoltaic systems and their mounting fixtures. Background Technology

[0002] Currently, photovoltaic technology is being used more and more widely as a new energy source. For example, photovoltaic products are integrated into buildings to achieve building photovoltaic integration. This not only does not affect the power generation capacity of the photovoltaic products themselves, but also allows the photovoltaic products to be used as building materials to form parts such as roofs and walls, thereby improving the aesthetics and practicality of buildings.

[0003] Since most photovoltaic (PV) products are installed outdoors, they will suffer varying degrees of damage as they age, necessitating replacement. However, current PV product installation methods mostly involve directly screwing the PV products onto the mounting bracket. Since a single set of screws has a limited fixing range, when the individual PV product to be fixed is large, multiple sets of screws are usually required for the fixing operation, making the replacement process cumbersome.

[0004] In addition, building-integrated photovoltaics (BIPV) technology should also focus on solving problems such as drainage and heat dissipation in order to extend the lifespan of photovoltaic products. Utility Model Content

[0005] To address the aforementioned technical problems and achieve at least one advantage of this application, this application provides a fixing clamp, wherein the fixing clamp comprises:

[0006] A first clamp, a second clamp, a third clamp, a first adjusting member, and at least one second adjusting member, wherein the first clamp and the second clamp are at least partially opposite and spaced apart to form an adjustable first clamping opening, the first adjusting member is synchronously connected to the first clamp and the second clamp in a manner that allows the first clamp and the second clamp to move closer and further apart relative to each other, the second clamp and the third clamp are also at least partially opposite and spaced apart to form an adjustable second clamping opening, the second adjusting member is synchronously connected to the second clamp and the third clamp in a manner that allows the second clamp and the third clamp to move closer and further apart relative to each other.

[0007] According to one embodiment of this application, the first clamping member extends toward the second clamping member to form a first clamping arm, and the second clamping member correspondingly forms a second clamping arm, and the first clamping arm and the second clamping arm are disposed opposite to each other and spaced apart at the same vertical height to form the first clamping opening.

[0008] According to one embodiment of this application, the first adjusting member includes a first through member and a first movable member, wherein the first through member is configured to simultaneously penetrate the first clamp and the second clamp, and the first through member extends radially outward integrally for a predetermined length to form a first step at the end, the first step being configured to abut against the first clamp, and the first movable member being axially movable to the other end of the first through member away from the first step to abut against the second clamp, thereby when the first through member and the first movable member move relative to each other, the first movable member is configured to move relatively closer to and away from the first step of the first through member, so that the first clamp and the second clamp move relatively closer to and away from each other.

[0009] According to one embodiment of this application, each of the second adjusting members includes a second through member and a second movable member, wherein the second through member is configured to simultaneously penetrate the second clamp and the third clamp, and the second through member extends radially outward integrally for a predetermined length to form a second step at its end, the second step being configured to abut against the third clamp, and the second movable member being axially movably connected to the other end of the second through member away from the second step to abut against the second clamp, thereby enabling the second through member and the second movable member to move relative to each other, and thus, when the second through member and the second movable member move relative to each other, the second movable member is configured to move relatively closer to and away from the second step of the second through member, so that the second clamp and the third clamp move relatively closer to and away from each other.

[0010] According to one embodiment of this application, the fixing clamp further includes a fourth clamp and a third adjusting member, wherein the third clamp and the fourth clamp are at least partially disposed opposite to each other and spaced apart to form an adjustable third clamping opening, the third adjusting member is synchronously connected to the third clamp and the fourth clamp in a manner that allows the third clamp and the fourth clamp to move closer and further apart relative to each other, and the second clamping opening is disposed between the first clamping opening and the third clamping opening.

[0011] According to one embodiment of this application, the third clamping member extends toward the fourth clamping member to form a third clamping arm, and the fourth clamping member correspondingly forms a fourth clamping arm. The third clamping arm and the fourth clamping arm are disposed opposite to each other and spaced apart at the same vertical height to form the third clamping opening.

[0012] According to one embodiment of this application, the third adjusting member includes a third through member and a third movable member. The third through member is configured to simultaneously penetrate the third clamp and the fourth clamp, and the third through member extends radially outward by a predetermined length to form a third step at its end. The third step is configured to abut against the fourth clamp. The third movable member is axially movable to the other end of the third through member away from the third step to abut against the third clamp. Thus, when the third through member and the third movable member move relative to each other, the third movable member is configured to move relatively closer to and away from the third step of the third through member, so that the third clamp and the fourth clamp move relatively closer to and away from each other.

[0013] According to one embodiment of this application, the photovoltaic system includes:

[0018] According to one embodiment of this application, the main support frame and the secondary support frame are configured to bend synchronously toward the second clamp in a predetermined manner, so that the main support frame forms a main tilted head at the top, and the secondary support frame also forms a secondary tilted head adjacent to the main tilted head. The second clamp is configured to be recessed in a predetermined manner to form a receiving space communicating with the second clamping opening together with the third clamp. The second clamp also extends a predetermined length toward the third clamp at the second clamping opening to form a second anti-detachment part. The third clamp forms a third anti-detachment part at a position opposite to the second anti-detachment part, so that the second anti-detachment part and the third anti-detachment part form the second clamping opening. Then, when the second clamp and the third clamp approach each other, one of the main tilted heads and at least one of the secondary tilted heads are configured to be able to synchronously pass through the second clamping opening and be at least partially received in the receiving space, and the second anti-detachment part is located on the movement path of the main tilted head and the secondary tilted head leaving the second clamping opening.

[0025] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0026] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] refer to Figures 1 to 3 A photovoltaic system according to a preferred embodiment of the present application will be described in detail below. The photovoltaic system includes a connecting bracket 10, at least one photovoltaic unit 20 and a plurality of fixing clamps 30.

[0029] Specifically, the connecting bracket 10 includes at least two main support frames 11, wherein the main support frames 11 are arranged opposite to each other and spaced apart, and a connecting channel 1001 is formed between two adjacent main support frames 11. The photovoltaic unit 20 is disposed in the connecting channel 1001 between the two adjacent main support frames 11 by means of the fixing clamp 30.

[0030] Preferably, the bottom of each main support frame 11 extends outward in a circumferential direction for a predetermined length to form at least one foot 111 for supporting the photovoltaic system as a whole.

[0031] In one embodiment, such as Figures 1 to 3 As shown, the connecting bracket 10 further includes at least one secondary support frame 12, wherein the secondary support frame 12 is disposed in the connecting channel 1001, and the two ends of one secondary support frame 12 are respectively connected to two adjacent main support frames 11. The secondary support frame 12 forms a channel 1201 below the photovoltaic unit 20, with its opening facing the photovoltaic unit 20 and communicating with the connecting channel 1001. The channel 1201 is configured to extend in a direction parallel to the extending direction of the connecting channel 1001 to communicate with the outside.

[0032] Those skilled in the art will understand that the photovoltaic unit 20 generates a large amount of heat during the power generation process. Since the channel 1201 is connected to the outside, a predetermined amount of airflow is allowed to circulate in the channel 1201, so that the part of the photovoltaic unit 20 facing the channel 1201 can be flowed through by the airflow in the channel 1201, so that the heat flows and the photovoltaic unit 20 is dissipated.

[0033] In addition, when the photovoltaic system is exposed to rain or snow, some of the rain and snow will enter the channel 1201 through the connection gap between the connecting bracket 10 and the photovoltaic unit 20, and then gradually flow out along the extension direction of the channel 1201 under the action of gravity, thereby preventing the rain and snow from staying inside the photovoltaic system for a long time and affecting the power generation of the photovoltaic unit 20.

[0034] Preferably, the secondary support frame 12 is arranged to extend toward the photovoltaic unit 20 to form a branch 121 at the middle position of the channel 1201. The branch 121 extends in a direction parallel to the extension direction of the channel 1201, so that the channel 1201 is divided into two parts. In this way, the middle part of the photovoltaic unit 20 disposed in the connecting channel 1001 can be supported by the branch 121 of the secondary support frame 12, thereby avoiding the situation where the photovoltaic unit 20 collapses due to the lack of support in the middle under the influence of adverse external factors.

[0035] Preferably, the channel 1201 is configured to extend at an angle so that rain, snow, or other substances entering the channel 1201 can more easily detach from the channel 1201 under the action of gravity.

[0036] More preferably, the connecting bracket 10 further includes at least one secondary support frame 13, wherein one of the secondary support frames 13 is disposed between two adjacent main support frames 11 and below the secondary support frame 12, for supporting the secondary support frame 12. Furthermore, the bottom of the secondary support frame 13 is provided to extend outwardly along the circumferential direction by a predetermined length to form at least one support portion 131, thereby increasing the support area, so that the photovoltaic unit 20 can be stably supported, and the channel 1201 can also be stably maintained.

[0037] Specifically, each of the fixing clamps 30 includes a first clamp 31, a second clamp 32, a third clamp 33, a first adjusting member 34, and at least one second adjusting member 35, wherein the first clamp 31 and the second clamp 32 are at least partially opposite and spaced apart to form an adjustable first clamping opening 301. The first adjusting member 34 is synchronously connected to the first clamp 31 and the second clamp 32 in a manner that allows the first clamp 31 and the second clamp 32 to move closer and further apart relative to each other, so that the size of the first clamping opening 301 is adapted to the peripheral dimensions of one of the photovoltaic units 20.

[0038] The second clamp 32 is also at least partially opposite and spaced from the third clamp 33 to form an adjustable second clamping opening 302. The second adjusting member 35 is synchronously connected to the second clamp 32 and the third clamp 33 in a manner that allows the second clamp 32 and the third clamp 33 to move closer and further apart relative to each other, so that the size of the second clamping opening 302 is adapted to the top dimension of one of the main support frames 11.

[0039] Those skilled in the art will understand that the fixing clamp 30 can be fixed to the main support frame 11 by adjusting the size of the second clamping opening 302 to fit the top size of the main support frame 11. At this time, the fixing clamp 30 can also be fixed to at least a portion of the periphery of a photovoltaic unit 20 by adjusting the size of the first clamping opening 301 to fit the periphery size of the photovoltaic unit 20. In this way, the top of a main support frame 11 can be fixed by multiple fixing clamps 30, so that each photovoltaic unit 20 disposed in the connection channel 1001 can be simultaneously clamped by multiple fixing clamps 30 from different positions to hold its periphery, so that each photovoltaic unit 20 can be fixed in position in the connection channel 1001.

[0040] In this way, when replacing the photovoltaic unit 20, the size of the first clamp 301 can be adjusted by the first adjusting member 34 so that the photovoltaic unit 20 is no longer clamped, and thus the photovoltaic unit 20 can be directly replaced.

[0041] Specifically, the first clamp 31 extends toward the second clamp 32 to form a first clamping arm 311, and the second clamp 32 correspondingly forms a second clamping arm 321. The first clamping arm 311 and the second clamping arm 321 are arranged opposite to each other and spaced apart at the same vertical height to form the first clamping opening 301. Thus, when the first clamp 31 and the second clamp 32 move closer and further apart relative to each other by means of the first adjusting member 34, the first clamping arm 311 and the second clamping arm 321 can move closer and further apart relative to each other so that the size of the first clamping opening 301 can be adjusted.

[0042] Preferably, the first clamp 31 extends toward the second clamp 32 to form a first guide portion 312, and the second clamp 32 correspondingly forms a second guide groove 3201 with an inner diameter matching the outer diameter of the first guide portion 312 toward the first guide portion 312 to restrict the movement of the first guide portion 312. Thus, when the first clamp 31 and the second clamp 32 move closer and further apart relative to each other, the first guide portion 312 is configured to move along the forming direction of the second guide groove 3201 in a predetermined manner.

[0043] It is worth mentioning that the way to restrict the relative movement of the first clamp 31 and the second clamp 32 is not unique. For example, as deformable, the second guide groove 3201 is configured to be formed from the first clamp 31 toward the second clamp 32, and the first guide portion 312 is configured to be formed from the second clamp 32 toward the second guide groove 3201. Furthermore, the outer diameter of the first guide portion 312 formed by the second clamp 32 is also adapted to the inner diameter of the second guide groove 3201 formed by the first clamp 31. In this way, the first clamp 31 and the second clamp 32 can also move closer and further apart relative to each other in a predetermined manner to adjust the size of the first clamping opening 301.

[0044] More preferably, the first clamp 31 is provided with at least one first protrusion 313 on the outer periphery of the first guide portion 312, and the second clamp 32 is provided with the same number of second abutment portions 322 on the inner wall of the second guide groove 3201 as the first protrusion 313. The second abutment portion 322 and the first protrusion 313 are located at different positions at the same vertical height. Thus, when the first clamp 31 and the second clamp 32 move away from each other, the second abutment portion 322 is set to move closer to the first protrusion 313 and gradually abut against each other.

[0045] It is understood that when the first clamp 31 and the second clamp 32 move away from each other to enlarge the first clamping opening 301, the first protruding edge 313 moves with the first clamp 31 and gradually abuts against the second abutting part 322 to limit the distance between the first clamp 31 and the second clamp 32, thereby limiting the range of enlargement of the first clamping opening 301.

[0046] Specifically, in one example, such as Figure 4 As shown, the first adjusting member 34 includes a first through member 341 and a first movable member 342. The first through member 341 is configured to simultaneously penetrate the first clamp 31 and the second clamp 32, and the first through member 341 extends radially outward integrally for a predetermined length to form a first step 3411 at its end. The first step 3411 is configured to abut against the first clamp 31. The first movable member 342 is movably connected to the other end of the first through member 341 away from the first step 341 along the axial direction of the first through member 341 to abut against the second clamp 32. Thus, when the first through member 341 and the first movable member 342 move relative to each other, the first movable member 342 is configured to move relatively closer to and away from the first step 3411 of the first through member 341, so that the first clamp 31 and the second clamp 32 move relatively closer to and away from each other.

[0047] It is understandable that, since the first step 3411 abuts against the first clamp 31 and the first moving member 342 abuts against the second clamp 32, during the relatively close movement of the first step 3411 and the first moving member 342, the first clamp 31 and the second clamp 32 are pressed against each other and move closer to each other, so that the first clamping opening 301 is reduced, thereby clamping the photovoltaic unit 20.

[0048] It is worth mentioning that by having the first step 3411 abut against the second clamp 32 and the first moving member 342 abut against the first clamp 31, the first clamp 31 and the second clamp 32 can also remain close to each other as the first step 3411 and the first moving member 342 approach each other, thereby making the first clamping opening 301 smaller.

[0049] Preferably, the first penetrating member 341 is configured to simultaneously penetrate the first clamp 31 and the second clamp 32 in a manner away from the first clamping opening 301.

[0050] Preferably, the first adjusting member 34 further includes two first washers 343, wherein the first through member 341 is configured to simultaneously pass through the inner rings of the two first washers 343, and one of the two first washers 343 is disposed between the first clamp 31 and the first step 3411, and the other of the two first washers 343 is disposed between the second clamp 32 and the first moving member 342, so that when the first step 3411 and the first moving member 342 move closer and further away relative to each other, the two first washers 343 are configured to move closer and further away relative to each other.

[0051] It should be noted that the two first washers 343 are used to prevent the first clamp 31 from being excessively abutted by the first step 3411, and to prevent the second clamp 32 from being excessively abutted by the first moving member 342, respectively.

[0052] Furthermore, the first adjusting member 34 also includes a first elastic element 344, which is disposed between the first clamp 31 and the second clamp 32. The two ends of the first elastic element 344 are respectively configured to abut against the first clamp 31 and the second clamp 32. Thus, when the first clamp 31 and the second clamp 32 move closer to each other, the first elastic element 344 is configured to deform along its own axial direction to generate elastic force. In a preferred embodiment, the first penetrating member 341 penetrates the first elastic element 344 along its axial direction.

[0053] It should be noted that the first elastic element 344 is configured as a spring. Therefore, when the first clamp 31 and the second clamp 32 approach each other to clamp the photovoltaic unit 20, the elastic force of the first elastic element 344 causes the first clamp 31 and the second clamp 32 to be subjected to resistance forces opposite to their own direction of movement during relative movement, thereby ensuring the tension effect. In this way, the photovoltaic unit 20 can be prevented from being damaged by over-clamping.

[0054] Preferably, the first through member 341 is configured as a screw, and the first movable member 342 is configured as a nut. That is, in one embodiment, the first movable member 342 is connected to the first through member 341 by a threaded connection. Preferably, the second clamping member 32 extends toward the first movable member 342 to form a second limiting groove 3202, and the first movable member 342 is configured such that at least a portion of its periphery abuts against the inner wall forming the second limiting groove 3202 to restrict the first movable member 342 from rotating axially along the first through member 341. In this way, the first movable member 342 is fixed in position, so that when adjusting the size of the first clamping opening 301, the first clamping member 31 and the second clamping member 32 can be kept in relative movement simply by moving the first through member 341, thereby facilitating the operation of adjusting the first clamping opening 301.

[0055] As an example, such as Figure 4 As shown, the third clamp 33 is provided with a third anti-slip structure 331 facing the second clamp 32. The third anti-slip structure 331 is located at the second clamping opening 302. When the second clamping opening 302 is adapted to the top size of the main support frame 11, the third anti-slip structure 331 of the third clamp 33 is abutted against the main support frame 11 by the second adjusting member 35, thereby fixing the second clamp 32 and the third clamp 33 on the main support frame 11. At the same time, the photovoltaic unit 20, which is jointly clamped by the first clamp 31 and the second clamp 32, is also fixed in position.

[0056] As an example, such as Figure 5 As shown, the second clamp 32 is provided with a second anti-slip structure 323 facing the second clamp 33. The second anti-slip structure 323 is located at the second clamping opening 302. When the second clamping opening 302 is adapted to the top size of the main support frame 11, the second anti-slip structure 323 of the second clamp 32 is abutted against the main support frame 11 by the second adjusting member 35, so that the second clamp 32 and the third clamp 33 are clamped on the main support frame 11. At the same time, the photovoltaic unit 20, which is jointly clamped by the first clamp 31 and the second clamp 32, is also fixed in position.

[0057] In one embodiment, such as Figure 2 As shown, the main support frame 11 and the secondary support frame 12 are configured to bend synchronously toward the second clamp 32 in a predetermined manner, so that the main support frame 11 forms a main tilted head 112 at the top, and the secondary support frame 12 also forms a secondary tilted head 122 adjacent to the main tilted head 112. Figure 4As shown, the second clamp 32 is configured to be recessed in a predetermined manner to form a receiving space 3301 communicating with the third clamp 33 in the second clamping opening 302. Furthermore, the second clamp 32 extends a predetermined length towards the third clamp 33 at the second clamping opening 302 to form a second anti-detachment portion 324. Correspondingly, the third clamp 33 forms a third anti-detachment portion 332 at a position opposite to the second anti-detachment portion 324, so that the second clamping opening 302 is formed between the second anti-detachment portion 324 and the third anti-detachment portion 332. Then, when the second clamp 32 and the third clamp 33 approach each other, one of the main tilting heads 112 and at least one of the secondary tilting heads 122 are configured to simultaneously pass through the second clamping opening 302 and be at least partially received in the receiving space 3301, and the second anti-detachment portion 324 is located on the movement path of the main tilting head 112 and the secondary tilting head 122 as they detach from the second clamping opening 302.

[0058] In another embodiment, the main support frame 11 and the secondary support frame 12 are configured to bend synchronously toward the third clamp 33 in a predetermined manner, such that the main support frame 11 forms a main tilted head 112 at its top, and the secondary support frame 12 also forms a secondary tilted head 122 adjacent to the main tilted head 112. Figure 5 As shown, the third clamp 33 is configured to be recessed in a predetermined manner to form a receiving space 3301 communicating with the second clamp 32 in the second clamping opening 302. Furthermore, the third clamp 33 extends a predetermined length toward the second clamp 32 at the second clamping opening 302 to form a third anti-detachment portion 324. Correspondingly, the second clamp 32 forms a second anti-detachment portion 324 at a position opposite to the third anti-detachment portion 324, so that the second clamping opening 302 is formed between the second anti-detachment portion 324 and the third anti-detachment portion 332. Then, when the second clamp 32 and the third clamp 33 approach each other, one of the main tilting heads 112 and at least one of the secondary tilting heads 122 are configured to simultaneously pass through the second clamping opening 302 and be at least partially received in the receiving space 3301, and the second anti-detachment portion 324 is located on the movement path of the main tilting head 112 and the secondary tilting head 122 as they detach from the second clamping opening 302.

[0059] It is understood that the fixing clamp 30 clamps the main support frame 11 and the auxiliary support frame 12 together through the second clamp 32 and the third clamp 33. That is, one of the main tilting heads 112 and at least one of the auxiliary tilting heads 122 pass through the second clamping opening 302 and are located in the receiving space 3301. As the second clamping opening 302 is continuously reduced, the second anti-detachment part 324 gradually becomes able to prevent the main tilting head 112 and the auxiliary tilting head 122 from leaving the receiving space 3301. Then, when the second clamping opening 302 is adjusted to a predetermined size, the fixing clamp 30 as a whole can be fixed on the connecting bracket 10.

[0060] Specifically, in one example, such as Figure 4 As shown, each of the second adjusting members 35 includes a second through member 351 and a second movable member 352. The second through member 351 is configured to simultaneously penetrate the second clamp 32 and the third clamp 33, and the second through member 351 extends radially outward integrally for a predetermined length to form a second step 3511 at its end. The second step 3511 is configured to abut against the third clamp 33. The second movable member 352 is movably connected to the other end of the second through member 351 away from the second step 3511 along the axial direction of the second through member 351 to abut against the second clamp 32. Thus, when the second through member 351 and the second movable member 352 move relative to each other, the second movable member 352 is configured to move relatively closer to and away from the second step 3511 of the second through member 351, so that the second clamp 32 and the third clamp 33 move relatively closer to and away from each other.

[0061] It is understandable that, since the second step 3511 abuts against the third clamp 33 and the second moving member 352 abuts against the second clamp 32, during the relatively close movement of the second through member 351 and the second moving member 352, the second clamp 32 and the third clamp 33 are pressed against each other and move closer to each other, so that the second clamping opening 302 is reduced, thereby clamping the main support frame 11.

[0062] Similarly, by having the second step 3511 abut against the second clamp 32 and the second moving member 352 abut against the third clamp 33, the second clamp 32 and the third clamp 33 can also remain close to each other as the second through member 351 and the second moving member 352 approach each other, thereby reducing the size of the second clamping opening 302.

[0063] Preferably, the second through member 351 is configured to simultaneously penetrate the second clamp 32 and the third clamp 33 in a manner away from the second clamping opening 302.

[0064] Preferably, the second adjusting member 35 further includes two second washers 353, wherein the second through member 351 is configured to simultaneously pass through the inner rings of the two second washers 353, and the other second washer 353 of the two second washers 353 is disposed between the second clamp 32 and the second moving member 352, and one of the two second washers 353 is disposed between the third clamp 33 and the second step 3511, so that when the second step 3511 and the second moving member 352 move closer and further away relative to each other, the two second washers 353 are configured to move closer and further away relative to each other.

[0065] It should be noted that the two second washers 353 are used to prevent the second clamp 32 from being excessively abutted by the second moving member 352, and to prevent the third clamp 33 from being excessively abutted by the second step 3511.

[0066] Furthermore, each of the second adjusting members 35 also includes a second elastic member 354, which is disposed between the second clamp 32 and the third clamp 33. The two ends of the second elastic member 354 are respectively configured to abut against the second clamp 32 and the third clamp 33. Thus, when the second clamp 32 and the third clamp 33 move closer to each other, the second elastic member 354 is configured to deform along its own axial direction to generate elasticity. In a preferred embodiment, the second through member 351 passes through the second elastic member 354 along its axial direction.

[0067] It should be noted that the second elastic element 354 is also configured as a spring. Therefore, when the second clamp 32 and the third clamp 33 approach each other to clamp the main support frame 11, due to the elastic force of the second elastic element 354, the second clamp 32 and the third clamp 33 are respectively subjected to resistance forces opposite to their own direction of movement during relative movement, thereby ensuring the tension effect. In this way, the main support frame 11 is difficult to be over-clamped.

[0068] Preferably, the second through member 351 is configured as a screw, and the second movable member 352 is configured as a nut, that is, in one embodiment, the second movable member 352 is connected to the second through member 351 by means of a threaded connection.

[0069] In a preferred embodiment, such as Figure 6As shown, the fixing clamp 30 further includes a fourth clamp 36 and a third adjusting member 37, wherein the third clamp 33 and the fourth clamp 36 are at least partially opposite and spaced apart to form an adjustable third clamping opening 303. The third adjusting member 37 is synchronously connected to the third clamp 33 and the fourth clamp 36 in a manner that allows the third clamp 33 and the fourth clamp 36 to move closer and further apart relative to each other, so that the size of the third clamping opening 303 is adapted to the peripheral dimensions of one of the photovoltaic units 20.

[0070] It is worth mentioning that the second clamp 302 is disposed between the first clamp 301 and the third clamp 303.

[0071] It is understood that the fixing clamp 30 can also clamp at least a portion of the periphery of the photovoltaic unit 20 by adjusting the size of the third clamp 303 to fit the periphery size of the photovoltaic unit 20.

[0072] In other words, when the fixing clamp 30 is fixed to the top of the main support frame 11 through the second clamping slot 302, the fixing clamp 30 can clamp one photovoltaic unit 20 on each side of the main support frame 11 through the first clamping slot 301 and the third clamping slot 303, specifically as follows: Figure 1 and Figure 2 As shown.

[0073] Preferably, the third clamp 33 extends toward the fourth clamp 36 to form a third clamping arm 333, and the fourth clamp 36 correspondingly forms a fourth clamping arm 361. The third clamping arm 333 and the fourth clamping arm 361 are positioned opposite each other and spaced apart at the same vertical height to form the third clamping opening 303. Thus, when the third clamp 33 and the fourth clamp 36 move closer and further apart relative to each other by means of the third adjusting member 37, the third clamping arm 333 and the fourth clamping arm 361 can move closer and further apart relative to each other, so that the size of the third clamping opening 303 can be adjusted.

[0074] Preferably, the fourth clamp 36 extends toward the third clamp 33 to form a fourth guide portion 362, and the third clamp 33 correspondingly forms a third guide groove 3302 with an inner diameter matching the outer diameter of the fourth guide portion 362 toward the fourth guide portion 362 to restrict the movement of the fourth guide portion 362. Thus, when the third clamp 33 and the fourth clamp 36 move closer and further apart relative to each other, the fourth guide portion 362 is configured to move along the forming direction of the third guide groove 3302 in a predetermined manner.

[0075] It is worth mentioning that the way to restrict the relative movement of the third clamp 33 and the fourth clamp 36 is not unique. For example, as a deformable form, the third guide groove 3302 is configured to be formed by the fourth clamp 36 toward the third clamp 33, and the fourth guide portion 362 is configured to be formed by the third clamp 33 correspondingly toward the third guide groove 3302. Furthermore, the outer diameter of the fourth guide portion 362 formed by the third clamp 33 is also adapted to the inner diameter of the third guide groove 3302 formed by the fourth clamp 36. In this way, the third clamp 33 and the fourth clamp 36 can also move relatively closer and further apart in a predetermined manner to adjust the size of the third clamping opening 303.

[0076] More preferably, the fourth clamp 36 is provided with an additional fourth protrusion 363 on the outer periphery of the fourth guide portion 362, and the third clamp 33 is provided with the same number of third abutment portions 334 as the fourth protrusion 363 on the inner wall of the third guide groove 3302. One third abutment portion 334 and one fourth protrusion 363 are located at different positions at the same vertical height. Thus, when the third clamp 33 and the fourth clamp 36 move away from each other, one third abutment portion 334 is positioned to move closer to one fourth protrusion 363 and gradually abut against each other.

[0077] It is understood that when the third clamp 33 and the fourth clamp 36 move away from each other to enlarge the third clamping opening 303, the fourth protruding edge 363 moves with the fourth clamp 36 and gradually abuts against the third abutting part 334 to limit the distance between the third clamp 33 and the fourth clamp 36, thereby limiting the enlargement range of the third clamping opening 303.

[0078] Specifically, in one example, such as Figure 6As shown, the third adjusting member 37 includes a third through member 371 and a third moving member 372. The third through member 371 is configured to simultaneously penetrate the third clamp 33 and the fourth clamp 36, and the third through member 371 extends radially outward integrally for a predetermined length to form a third step 3711 at its end. The third step 3711 is configured to abut against the fourth clamp 36. The third moving member 372 is movably connected to the other end of the third through member 371 away from the third step 3711 along the axial direction of the third through member 371 to abut against the third clamp 33. Thus, when the third through member 371 and the third moving member 372 move relative to each other, the third moving member 372 is configured to move relatively closer to and away from the third step 3711 of the third through member 371, so that the third clamp 33 and the fourth clamp 36 move relatively closer to and away from each other.

[0079] It is understood that, as the third step 3711 abuts against the fourth clamp 36 and the third moving member 372 abuts against the third clamp 33, during the relatively close movement of the third step 3711 and the third moving member 372, the fourth clamp 36 and the third clamp 33 are pressed against each other and move closer to each other, so that the third clamping opening 303 is reduced, thereby clamping the photovoltaic unit 20.

[0080] It is worth mentioning that, similarly, the third clamp 33 and the fourth clamp 36 can remain close to each other as the third step 3711 and the third moving member 372 approach each other, so that the third clamp 303 can be reduced in size.

[0081] Preferably, the third penetrating member 371 is configured to simultaneously penetrate the third clamp 33 and the fourth clamp 36 in a manner away from the third clamping opening 303.

[0082] Preferably, the third adjusting member 37 further includes two third washers 373, wherein the third through member 371 is configured to simultaneously penetrate the inner rings of the two third washers 373, and one of the two third washers 373 is disposed between the third step 3711 and the fourth clamp 36, and the other of the two third washers 373 is disposed between the third clamp 33 and the third moving member 372, so that when the third step 3711 and the third moving member 372 move relatively closer and further apart, the two third washers 373 are configured to move relatively closer and further apart.

[0083] It should be noted that the two third washers 373 are used to prevent the third clamp 33 from being excessively abutted by the third moving member 372, and to prevent the fourth clamp 36 from being excessively abutted by the third step 3711, respectively.

[0084] Furthermore, the third adjusting member 37 further includes a third elastic element 374, which is disposed between the third clamp 33 and the fourth clamp 36. The two ends of the third elastic element 374 are respectively configured to abut against the third clamp 33 and the fourth clamp 36. Thus, when the third clamp 33 and the fourth clamp 36 move closer together relative to each other, the third elastic element 374 is configured to deform along its own axial direction to generate elasticity. In a preferred embodiment, the third penetrating member 371 penetrates the third elastic element 374 along its axial direction.

[0085] It should be noted that the third elastic element 374 is implemented as a spring. Therefore, when the third clamp 33 and the fourth clamp 36 approach each other to clamp the photovoltaic unit 20, due to the elastic force of the third elastic element 374, the third clamp 33 and the fourth clamp 36 are respectively subjected to resistance forces opposite to their own direction of movement during relative movement, thereby ensuring the tension effect. In this way, the photovoltaic unit 20 can be prevented from being damaged by over-clamping.

[0086] Preferably, the third through member 371 is also configured as a screw, and the third moving member 372 is also configured as a nut. That is, in one embodiment, the third moving member 372 is connected to the third through member 371 by a threaded connection. Preferably, the third clamping member 33 extends toward the third moving member 372 to form a third limiting groove 3303, and the third moving member 372 is configured such that at least a portion of its periphery abuts against the inner wall forming the third limiting groove 3303 to restrict the third moving member 372 from rotating axially along the third through member 371. In this way, the third moving member 372 is fixed in position, so when adjusting the size of the third clamping opening 303, the third clamping member 33 and the fourth clamping member 36 can be kept in relative movement simply by moving the third through member 371, thereby facilitating the operation of adjusting the third clamping opening 303.

[0087] In addition, the photovoltaic system also includes the same number of protective units 40 as the fixing clamp 30. Preferably, each protective unit 40 includes a pair of first protective members 41, wherein both first protective members 41 are made of flexible material and are disposed opposite to and spaced apart from each other in the first clamping opening 301. The two first protective members 41 are detachably connected to the first clamping arm 311 of the first clamping member 31 and the second clamping arm 321 of the second clamping member 32, respectively.

[0088] Understandably, when the first clamp 31 and the second clamp 32 are relatively close, the two first spacers 41 follow the first clamping arm 311 and the second clamping arm 321, respectively, and remain close to each other. In other words, the first clamp 31 and the second clamp 32 indirectly clamp the photovoltaic unit 20 through the first spacers 41. At the same time, since the first spacers 41 are both made of flexible material, the photovoltaic unit 20 is unlikely to be damaged by excessive clamping by the first clamp 31 and the second clamp 32.

[0089] More preferably, each of the protective units 40 further includes a pair of second protective members 42, wherein both second protective members 42 are made of flexible material and are disposed opposite to and spaced apart from each other in the third clamping opening 303, and the two second protective members 42 are respectively detachably connected to the third clamping arm 333 of the third clamping member 33 and the fourth clamping arm 361 of the fourth clamping member 36.

[0090] Understandably, when the third clamp 33 and the fourth clamp 36 are relatively close, the two second protective members 42 follow the third clamping arm 333 and the fourth clamping arm 361 and remain close to each other. That is, the third clamp 33 and the fourth clamp 36 indirectly clamp the photovoltaic unit 20 through the second protective members 42. At the same time, since the second protective members 42 are both made of flexible material, the photovoltaic unit 20 is unlikely to be damaged by excessive clamping by the third clamp 33 and the fourth clamp 36.
