Description

Technical Field

[0001] This application relates to the technical field of inverter installation, and particularly to an inverter installation structure for photovoltaic power generation. Background Art

[0002] Photovoltaic power generation is a power generation method that directly converts sunlight radiation into electrical energy. In photovoltaic power generation facilities, it is often necessary to install an inverter on the bracket where the photovoltaic panel is located.

[0003] When installing the inverter, multiple installation holes are often opened on the bracket of the photovoltaic panel. Fixing holes for bolts to pass through are provided at the four corners of the inverter. When installing the inverter, at least one operator often needs to lift the inverter and align the fixing holes on the inverter with the installation holes. Then, another operator passes the bolt through the aligned fixing holes and installation holes, and then screws the nut onto the bolt and tightens it. The inverter is installed on the bracket through the bolt and the nut.

[0004] Regarding the above related technologies, when installing the inverter, it is inconvenient to align the inverter, resulting in a relatively large amount of manpower required for installing the inverter. Summary of the Invention

[0005] In order to improve the problem of relatively large amount of manpower required for installing the inverter, this application provides an inverter installation structure for photovoltaic power generation.

[0006] An inverter installation structure for photovoltaic power generation provided by this application adopts the following technical solutions:

[0007] An inverter installation structure for photovoltaic power generation includes a photovoltaic panel bracket and an installation bracket. The installation bracket is used to connect the inverter main body. A cross frame is fixedly arranged on the photovoltaic panel bracket. The installation bracket is used to be installed on the cross frame. Bolt holes are opened on the cross frame. A clamping component is arranged on the installation bracket. The clamping component is used to be inserted into the bolt holes and be clamped with the cross frame. A holding mechanism for controlling the insertion or extraction of the clamping component into or out of the bolt holes is arranged on the installation bracket.

[0008] By adopting the above technical solutions, when an operator installs the inverter main body, the operator first moves the inverter main body to a predetermined position so that the clamping component can be aligned with the bolt holes. Then, the operator controls the holding mechanism and inserts the clamping component into the bolt holes, which can realize the clamping and fixing of the inverter main body, facilitating the pre-positioning and pre-fixing of the inverter main body. After the operator completes the pre-positioning and pre-fixing of the inverter main body, it is convenient for the operator to further fix the inverter main body, and can improve the problem of relatively large amount of manpower required for installing the inverter main body.

[0009] Optionally, the bolt hole is an oblong hole. The holding mechanism includes a box body, which is telescopically installed on the mounting bracket. A chute is provided on one side of the box body close to the cross frame, and the length direction of the chute is parallel to the length direction of the bolt hole;

[0010] The clamping component includes two clamping rods and a first spring rod for driving the two clamping rods to move away from each other. The two clamping rods are both slidably installed in the chute, and a clamping groove for clamping with the bolt hole is provided on one side of each of the two clamping rods facing away from each other.

[0011] By adopting the above technical solution, the operator first moves the inverter body to align the clamping rods with the bolt holes, and then inserts the two clamping rods into the bolt holes. With the help of the first spring rod driving the two clamping rods to move away from each other, the bottom wall of the clamping groove can be made to abut against the hole wall of the bolt hole, thereby realizing the clamping of the clamping rods with the cross frame.

[0012] Optionally, the holding mechanism further includes a telescopic sleeve, a holding seat and a driving component. The holding seat is connected to the mounting bracket through the telescopic sleeve, and the box body is fixedly connected to the side of the holding seat away from the telescopic sleeve;

[0013] The driving component includes two first hinge plates, both of which are hinged on the holding seat. The hinge axes of the two first hinge plates are parallel, and the two clamping rods are both located between the two first hinge plates.

[0014] By adopting the above technical solution, the operator controls the two first hinge plates to rotate and approach each other. When the first hinge plate abuts against the clamping rod, continuing to rotate the first hinge plate can drive the two clamping rods to approach each other.

[0015] Optionally, a mounting hole is provided at one end of the clamping rod away from the holding seat. The clamping component further includes a wedge block, which is located in the mounting hole. One side of the wedge block close to the box body is flush with the side wall of the clamping groove away from the holding seat. The holding mechanism further includes a transmission component for driving the wedge block to slide into or out of the mounting hole.

[0016] By adopting the above technical solution, after the clamping rod is inserted into the bolt hole, through the transmission component, the wedge block can be driven to slide out of the mounting hole. The wedge block abuts against the cross frame, which can limit the sliding of the clamping rod out of the bolt hole and improve the stability of the clamping of the clamping rod with the cross frame.

[0017] Optionally, a connection hole is formed at one end of the clamping rod close to the mounting bracket. The connection hole communicates with the mounting hole. The transmission assembly includes a connection shaft and a transmission gear. The connection shaft is located in the connection hole, the transmission gear is located in the mounting hole, and the transmission gear is coaxially and fixedly connected to the connection shaft. A rack is fixedly arranged on the wedge block, and the rack meshes with the transmission gear.

[0018] By adopting the above technical solution, when the operator controls the rotation of the connection shaft, the transmission gear can drive the rack to slide. When the rack slides, it can drive the wedge block to slide into or out of the mounting hole, realizing the control of the wedge block sliding into or out of the mounting hole.

[0019] Optionally, the transmission assembly further includes a torsion spring. The torsion spring is sleeved on the connection shaft, and one end of the torsion spring is fixedly connected to the inner side wall of the connection hole, and the other end is fixedly connected to the connection shaft.

[0020] By adopting the above technical solution, when the operator rotates the connection shaft, the rack can be driven to drive the wedge block to slide into the mounting hole, and the torsion spring undergoes elastic deformation; when the operator stops rotating the connection shaft, the torsion spring can drive the connection shaft to rotate in the reverse direction, thereby driving the rack to drive the wedge block to slide out of the mounting hole.

[0021] Optionally, the transmission assembly further includes a connecting rod. One end of the connection shaft extends out of the connection hole and is fixedly connected to the connecting rod, and the connecting rod is located outside the connection hole. The connecting rod is located between the two first hinge plates.

[0022] By adopting the above technical solution, when the operator controls the two first hinge plates to rotate and approach each other, the two connecting rods can be driven to rotate and approach each other, and the rotation of the connecting rod drives the connection shaft to rotate.

[0023] Optionally, the telescopic sleeve includes a second spring rod. One end of the second spring rod is fixedly connected to the holding seat, and the other end is fixedly connected to the mounting bracket.

[0024] By adopting the above technical solution, with the help of the second spring rod, the elastic telescoping of the telescopic sleeve is realized.

[0025] Optionally, the drive assembly further includes two clamping plates. The clamping plates are arranged corresponding to the first hinge plates one by one. The clamping plates are hinged to the corresponding first hinge plates. A third spring rod is connected between the two clamping plates, and the hinge axis of the clamping plate is parallel to the hinge axis of the first hinge plate.

[0026] By adopting the above technical solution, when the operator holds the two clamping plates, the two clamping plates can be made to approach each other. When the two clamping plates approach each other, they drive the two first hinge plates to approach each other, which is convenient for the operator's operation. After the operator releases the two clamping plates, the third spring rod can drive the two clamping plates to move away from each other. When the clamping plates move away from each other, they drive the first hinge plates to rotate and move away from each other.

[0027] Optionally, a plurality of bolt holes are arranged in sequence along the length direction of the cross frame. The mounting bracket is provided with a bent seat, and fixing holes are formed in the bent seat corresponding to the bolt holes. A limiting groove is formed in the cross frame along the length direction of the cross frame, and the limiting groove is used for slidably mounting the bent seat and the box body.

[0028] By adopting the above technical solution, the operator controls the driving assembly to drive the two clamping rods to approach each other, and then controls the box body to retract and approach the mounting bracket, so as to release the clamping of the clamping rods and the cross frame. Then, the operator controls the inverter body to slide along the cross frame. The cooperation of the limiting groove and the bent seat can support the inverter body, so as to facilitate the adjustment of the position of the inverter body. After the inverter body is adjusted to an appropriate position, the bolt is inserted into the fixing hole, and the inverter body can be locked by the bolt and the nut.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. When the operator installs the inverter body, the operator first moves the inverter body to a predetermined position, so that the clamping assembly is aligned with the bolt hole. Then the operator controls the holding mechanism and inserts the clamping assembly into the bolt hole, which can realize the clamping and fixing of the inverter body, which is beneficial to realize the pre-positioning and pre-fixing of the inverter body. After the operator completes the pre-positioning and pre-fixing of the inverter body, it is convenient for the operator to further fix the inverter body, and can improve the problem that more manpower is required during the installation of the inverter.

[0031] 2. The operator first moves the inverter body to align the clamping rods with the bolt holes, and then inserts the two clamping rods into the bolt holes. With the help of the first spring rod to drive the two clamping rods to move away from each other, the bottom wall of the clamping groove can be made to abut against the hole wall of the bolt hole, so as to realize the clamping of the clamping rods and the cross frame.

[0032] 3. After the clamping rods are inserted into the bolt holes, through the transmission assembly, the wedge block can be driven to slide out of the mounting hole. The wedge block abuts against the cross frame, which can limit the sliding of the clamping rods out of the bolt holes and improve the stability of the clamping of the clamping rods and the cross frame.

DETAILED DESCRIPTION

[0047] The following is combined with Figure 1-12 This application is described in further detail.

[0048] The present application embodiment discloses an inverter installation structure for photovoltaic power generation. Figure 1 , Figure 2 and Figure 3 A photovoltaic inverter mounting structure for power generation includes a photovoltaic panel bracket 1 and a mounting bracket 2. The mounting bracket 2 is fixedly mounted on the back of an inverter body 3. A cross frame 11 is detachably fixedly mounted on the photovoltaic panel bracket 1. The mounting bracket 2 is detachably fixedly connected to the inverter body 3. Bolt holes 111 are penetrated through the cross frame 11. A clamping component 4 is provided on the mounting bracket 2. The clamping component 4 is used to be inserted into the bolt hole 111 and clamped with the cross frame 11. A holding mechanism 5 for controlling the clamping component 4 to be inserted into or away from the bolt hole 111 is provided on the mounting bracket 2. When the operator is installing the inverter body 3, the operator first moves the inverter body 3 to a predetermined position so that the snap-on assembly 4 can be aligned with the bolt hole 111. The operator then controls the holding mechanism 5 and inserts the snap-on assembly into the bolt hole 111, thereby achieving snap-on fixation of the inverter body 3, which is beneficial for achieving pre-positioning and pre-fixing of the inverter. After the operator completes the pre-positioning and pre-fixing of the inverter, it is convenient for the operator to further fix the inverter, which can improve the problem of more manpower required when installing the inverter.

[0049] The photovoltaic panel support 1 includes a plurality of vertical supports 12. The adjacent supports 12 are connected by metal rods. The lower ends of the supports 12 are fixedly installed on the concrete base, which is beneficial to ensuring the stability of the supports 12. In the embodiment of the present application, there are two crossbars 11, and both crossbars 11 are horizontally arranged. The supports 12 and the crossbars 11 are both in the shape of long rods. A plurality of through holes 121 are formed in the supports 12 along the length direction of the supports 12, and a plurality of bolt holes 111 are arranged in sequence along the length direction of the crossbars 11. When installing the crossbars 11, the operator can adjust the distance and height between the two crossbars 11 according to the needs, then align the bolt holes 111 on the crossbars 11 with the through holes 121, and then pass the bolts through the bolt holes 111 and the through holes 121 and tighten the nuts, so as to firmly install the two ends of the crossbars 11 on the two supports 12 respectively. In the embodiment of the present application, the two crossbars 11 are arranged in sequence along the height direction of the supports 12.

[0050] Referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 , the installation bracket 2 includes a first installation bracket 21 and a second installation bracket 22. The first installation bracket 21 and the second installation bracket 22 are arranged in sequence along the vertical direction, and the first installation bracket 21 is located above the second installation bracket 22. The first installation bracket 21 and the second installation bracket 22 are both detachably and fixedly installed on the inverter main body 3; Installation seats 211 are integrally cast on both sides of the first installation bracket 21, and an installation seat 211 is also integrally cast on one side of the second installation bracket 22, and the other side is installed with a clamping component 4. Fixing holes are formed in the installation seats 211 corresponding to the bolt holes 111. After the pre-positioning of the inverter main body 3, the fixing holes can be aligned with the bolt holes 111, and then the bolts are passed through the fixing holes and the bolt holes 111 in sequence and the nuts are tightened, so that the installation bracket 2 can be firmly installed on the crossbar 11.

[0051] Referring to Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , the holding mechanism 5 includes a telescopic sleeve 51, a holding seat 52, a box body 53, a driving component 54 and a transmission component 55. One side of the telescopic sleeve 51 is fixedly connected to the lowermost second installation bracket 22, and the telescopic sleeve 51 and the installation seat 211 are located on opposite sides of the second installation bracket 22.

[0052] The telescopic sleeve 51 includes a first sleeve 511, a second sleeve 512 and a second spring rod 513. The second spring rod 513 is parallel to the first sleeve 511 and the second sleeve 512. The first sleeve 511 is welded to the second mounting bracket 22, and the second sleeve 512 is welded to the holding seat 52. The second sleeve 512 coaxially passes through the first sleeve 511. The second spring rod 513 is located inside the first sleeve 511 and is parallel to the axis of the first sleeve 511. One end of the second spring rod 513 is welded to the second mounting bracket 22, and the other end is welded to the holding seat 52. When the operator controls the telescopic sleeve 51 to retract, the third spring rod 6 undergoes elastic deformation. When the operator stops controlling the telescopic sleeve 51, the third spring rod 6 can drive the telescopic sleeve 51 to extend, realizing the telescopic installation of the holding seat 52 and the telescopic sleeve 51.

[0053] On the upper side of the side of the second mounting bracket 22 close to the first sleeve 511, a vertical handle 221 is welded. The handle 221 is in the shape of a long rod, and the operator can hold the handle 221.

[0054] Refer to Figure 8 、 Figure 9 and Figure 10 As shown in

[0055] A plurality of third spring rods 6 are connected between the two clamping plates 542. The third spring rods 6 are perpendicular to the two clamping plates 542. The two ends of the third spring rod 6 are respectively welded to the closer sides of the two clamping plates 542. The third spring rod 6 has a certain elasticity. Driven by the third spring rod 6, a certain distance can be maintained between the two clamping plates 542, so that a certain distance can be maintained between the two first hinge plates 541.

[0056] To vertically support the first hinge plate 541, the clamping plate 542, the second hinge plate 543, and the top seat 5431. A vertical insertion tube 521 is welded to the upper side of the holding seat 52. The upper end of the insertion tube 521 is open and slidably inserted with an insertion rod 522. The upper end of the insertion rod 522 is welded to the lower side of the top seat 5431. The lower end of the insertion rod 522 is coaxially welded with a fourth spring rod 523. The fourth spring rod 523 is located inside the insertion tube 521, and the lower end of the fourth spring rod 523 is fixedly connected to the bottom wall of the insertion tube 521. There are two insertion tubes 521, insertion rods 522, and fourth spring rods 523. The third spring rod 6 is located between the two insertion tubes 521. The third spring rod 6 is elastic and can keep a certain distance between the top seat 5431 and the holding seat 52.

[0057] Anti-slip patterns 7 are provided on the sides of the two clamping plates 542 away from each other. In the embodiment of the present application, the anti-slip patterns 7 can be anti-slip protrusions engraved on the clamping plates 542. Alternatively, the anti-slip patterns 7 can also be rubber strips adhered to the clamping plates 542.

[0058] After the operator unlocks the clamping of the clamping component 4 and the cross frame 11, when the operator holds the handle 221 and the two clamping plates 542 by hand, the two clamping plates 542 can be made to approach the handle 221, thereby driving the holding seat 52 to approach the handle 221, realizing the shortening of the telescopic sleeve 51. After the operator releases the holding of the clamping plates 542 and the handle 221, the holding seat 52 can be driven by the telescopic sleeve 51 to move away from the handle 221.

[0059] Refer to Figure 3 、 Figure 4 and Figure 5 and, the bolt hole 111 is an oval hole, and the length direction of the bolt hole 111 is consistent with the length direction of the cross frame 11. A sliding groove 531 is opened on the side of the box body 53 away from the telescopic sleeve 51. There is an opening on the side wall of the box body 53 away from the sliding groove 531 for the clamping rod 41 to pass through. The length direction of the sliding groove 531 is consistent with the length direction of the bolt hole 111.

[0060] Refer to Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 and Figure 11, the clamping component 4 includes clamping rods 41, first spring rods 42 and wedges 43. There are two clamping rods 41 and four first spring rods 42. Both clamping rods 41 are slidably installed in the chute 531. The length direction of the clamping rod 41 is parallel to the length direction of the telescopic sleeve 51, and the length direction of the clamping rod 41 is perpendicular to the length direction of the chute 531. Two first spring rods 42 correspond to one clamping rod 41. The first spring rod 42 is located on the side of its corresponding clamping rod 41 away from the other clamping rod 41. All four first spring rods 42 are located in the box body 53, and the first spring rod 42 is located on the side where the two clamping rods 41 are away from each other. The length direction of the first spring rod 42 is parallel to the length direction of the chute 531. One end of the first spring rod 42 is welded to its corresponding clamping rod 41, and the other end is welded to the inner side wall of the box body 53. The first spring rod 42 can pull the two clamping rods 41 away from each other.

[0061] One end of the clamping rod 41 away from the second mounting bracket 42 has a wedge head 411, and both ends of the clamping rod 41 are exposed outside the box body 53. The wedge head 411 is located outside the box body 53. The sides of the two wedge heads 411 away from each other are arc-shaped, and the distance between the sides of the two wedge heads 411 away from each other gradually decreases in the direction from the second mounting bracket 42 towards the wedge head 411. Limit blocks 412 are integrally cast on the clamping rods 41. The limit blocks 412 are located on the side where the two clamping rods 41 are away from each other, and the limit blocks 412 can be rectangular blocks. The limit blocks 412 are located in the box body 53. A clamping groove 413 is formed between the wedge head 411 and the limit block 412. The limit block 412 abuts against the inner side wall of the box body 53, and the limit block 412 prevents the clamping rod 41 from disengaging from the box body 53. With the help of the limit block 412, the stability of the sliding of the clamping rod 41 in the box body 53 is improved.

[0062] The operator first moves the inverter main body 3 to align the clamping rod 41 with the bolt hole 111, and then inserts the two clamping rods 41 into the bolt hole 111. The sides of the two wedge heads 411 away from each other abut against the hole wall of the bolt hole 111. The operator continues to insert the clamping rod 41 into the bolt hole 111, and the two wedge heads 411 can drive the two clamping rods 41 to approach each other. After the wedge head 411 passes through the bolt hole 111, the two clamping rods 41 move away from each other under the action of the first spring rod 42, and the bottom wall of the clamping groove 413 can abut against the hole wall of the bolt hole 111, thereby realizing the clamping of the clamping rod 41 to the cross frame 11 and pre-positioning and pre-fixing the inverter main body 3.

[0063] Refer to Figure 3 , Figure 4 and Figure 5, a limiting groove 112 is formed on one side of the cross frame 11 close to the inverter main body 3, and the bolt hole 111 is formed on the bottom wall of the limiting groove 112. The length direction of the limiting groove 112 is consistent with the length direction of the cross frame 11; the mounting seat 211 can slide in the limiting groove 112, and the operator can insert the box body 53 into the limiting groove 112; when the position of the inverter main body 3 needs to be adjusted, the operator can slide the mounting seat 211 and install it in the limiting groove 112. With the help of the limiting groove 112, the side wall of the limiting groove 112 can vertically support the mounting seat 211, so as to realize the vertical support of the inverter main body 3, which is convenient for the operator to adjust the position of the inverter main body 3.

[0064] Referring to Figure 8 , Figure 9 and Figure 10 , both of the two clamping rods 41 are located between the two first hinge plates 541. An arc-shaped groove 414 is formed at one end of the clamping rod 41 away from the wedge head 411. The first hinge plate 541 is located in the arc-shaped groove 414, and the first hinge plate 541 abuts against the clamping rod 41.

[0065] When the operator holds the two clamping plates 542, the two first hinge plates 541 can be made to approach each other, so as to drive the two clamping rods 41 to approach each other. Then, by controlling the box body 53 to retract and approach the mounting bracket 2, the clamping connection between the clamping rod 41 and the cross frame 11 can be released.

[0066] Referring to Figure 7 , Figure 11 and Figure 12 , Figure 12 In

[0067] , when the clamping rod 41 is sectioned along the horizontal plane, mounting holes 415 are formed on the upper sides of the wedge heads 411. The opening direction of the mounting holes 415 is perpendicular to the length direction of the clamping rod 41. There are two wedge blocks 43, and the wedge blocks 43 are arranged corresponding to the clamping rods 41 one by one. The wedge blocks 43 are slidably installed in the mounting holes 415, and the side of the wedge block 43 close to the box body 53 is flush with the side of the wedge head 411 close to the box body 53.

[0068] The torsion spring 553 is sleeved on the connecting rod 554. One end of the torsion spring 553 is fixedly connected to the inner side wall of the connecting hole 416, and the other end is fixedly connected to the connecting shaft 551. One end of the connecting shaft 551 extends out of the connecting hole 416 and is fixedly connected to the connecting rod 554. The connecting rod 554 is located outside the connecting hole 416. Both connecting rods 554 are located between the two first hinge plates 541, both connecting rods 554 are located between the two clamping plates 542, and the two racks 10 are located between the two transmission gears 552.

[0069] The side of the wedge block 43 away from the mounting hole 415 is an inclined surface, and the distance between the side of the wedge block 43 away from the mounting hole 415 and the clamping rod 41 gradually decreases in the direction from the box body 53 towards the wedge head 411. When the wedge head 411 is inserted into the bolt hole 111, the inclined surface of the wedge block 43 can abut against the hole wall of the bolt hole 111, thereby driving the wedge block 43 to slide into the mounting hole 415. After the wedge head 411 passes through the bolt hole 111, the wedge block 43 slides out of the mounting hole 415 under the drive of the torsion spring 553, which is beneficial to improving the convenience of inserting the clamping rod 41.

[0070] When the operator holds the two clamping plates 542, the two clamping plates 542 can drive the two connecting rods 554 to rotate and approach each other, thereby driving the transmission gear 552 to rotate. When the transmission gear 552 rotates, it drives the rack 10 to drive the wedge block 43 to slide into the mounting hole 415, and the torsion spring 553 undergoes elastic deformation, releasing the clamping between the wedge block 43 and the cross frame 11.

[0071] After the operator releases the clamping plate 542, under the drive of the torsion spring 553, the connecting shaft 551 drives the transmission gear 552 to rotate in the reverse direction, which can drive the wedge block 43 to slide out of the mounting hole 415.

[0072] A bearing 8 is sleeved on the outer side of the connecting shaft 551, and the bearing 8 is connected to the hole wall of the connecting hole 416. With the help of the bearing 8, the stable rotation of the connecting shaft 551 in the connecting hole 416 is ensured.

[0073] A slide rail 9 is provided in the mounting hole 415. The slide rail 9 is fixedly connected to the clamping rod 41.
