Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel engineering construction, in particular to a photovoltaic panel foundation pouring auxiliary kit structure. Background Art

[0002] Solar energy is an inexhaustible, green, and environmentally friendly resource. Photovoltaic power stations are a common type of equipment that converts solar energy into electricity. A photovoltaic power station project includes the construction of power generation equipment within the photovoltaic field and access roads within and outside the field. A photovoltaic field requires the construction of several photovoltaic sub-arrays, each equipped with several photovoltaic strings, combiner boxes, inverters, and photovoltaic panels. Each sub-array's equipment must be installed on photovoltaic foundation columns.

[0003] In the existing technology, most photovoltaic equipment constructed on land or rooftops requires measuring and marking the base position of each photovoltaic rack by marking and other positioning methods before construction, and then pouring the foundation into shape by pouring concrete using a simple template. Each bracket requires at least four bases, which results in a lot of preparatory work in the early stage of construction. In addition, the manual positioning and placement of the mold is relatively inaccurate, which can easily lead to deviations in the subsequent installation, resulting in splicing failures or stress in the splicing.

[0004] Based on this, the present invention designs a photovoltaic panel foundation casting auxiliary kit structure to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a photovoltaic panel foundation casting auxiliary kit structure to solve the problems proposed in the above background technology, such as the numerous preliminary construction preparations and the inaccurate manual positioning and placement of molds, which can easily lead to subsequent installation deviations, resulting in splicing failures or stress in splicing.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A photovoltaic panel foundation pouring auxiliary kit structure includes an intermediate column and multiple right-angle frames. A flip frame is rotatably connected to the top of the right-angle frame through a rotating shaft. Multiple groups of adjustment telescopic rods and extension telescopic rods are circumferentially connected to the intermediate column. One group of adjustment telescopic rods and extension telescopic rods are rotatably connected to each right angle of the right-angle frame. The extension telescopic rod is located above the adjustment telescopic rod. Tightening rods are slidably connected to both sides of the right-angle frame. One end of each tightening rod is rotatably connected to a fastening connecting rod, and the other end is fixedly connected to a tightening piece. The ends of the fastening connecting rods are commonly connected to a threaded ring. An internal screw sleeve is threadedly connected to the threaded ring. The internal screw sleeve is rotatably connected to the outside of the right-angle frame. Outer extension pressing pieces are fixedly connected to the sides of the flip frame. The tightening rods act on the outer extension pressing pieces to buckle the flip frame to the side of the right-angle frame and form a square. The rotating shafts of the right-angle frame and the flip frame extend outwards and the ends are fixedly connected to flip gears. A vertical rack is slidably connected to the side of the right-angle frame. The vertical rack meshes with the flip gear. A wedge-shaped block is fixedly connected below the tightening rod. The wedge-shaped block is located at the bottom of the vertical rack and they are slidably connected. The wedge-shaped block is used to lift or pull down the vertical rack when moving synchronously with the tightening rod to drive the flip gear to rotate, thereby making the flip frame rotate to close or open.

[0008] Among them, outer support plates are fixedly connected to the outside of the right-angle frames. The tightening rods pass through the outer support plates and are slidably matched with them. A transfer seat is fixedly connected to the inner side of the threaded ring. The fastening connecting rods are located on both sides of the internal screw sleeve and are rotatably connected to the transfer seat.

[0009] Among them, side slide rails are fixedly connected to the outside of the right-angle frames. One side of the vertical rack is slidably connected in the side slide rails. A connecting slideway is opened at the top of the wedge-shaped block. A connecting ball shaft is fixedly connected to the bottom of the vertical rack. The connecting ball shaft is located in the connecting slideway and they are slidably connected.

[0010] Among them, the adjustment telescopic rod includes a fixed outer cylinder, an internal rod, and an intermediate square rod. The fixed outer cylinder is fixedly connected to the side wall of the intermediate column. The internal rod is rotatably connected to the outside of the right-angle frame. The intermediate square rod is slidably connected to the middle of the internal rod. The internal rod is threadedly connected to the fixed outer cylinder. The intermediate square rod is completely sleeved in the middle of the fixed outer cylinder. The extension telescopic rod has the same structure as the adjustment telescopic rod, but the internal rod of the extension telescopic rod is a smooth rod and a tightening gear is fixedly connected to the outer wall. The tightening gear meshes with the outer ring of the internal screw sleeve.

[0011] Among them, the inner ends of the intermediate square rods of the adjustment telescopic rod and the extension telescopic rod are respectively fixedly connected to an adjustment cone wheel and a tightening cone wheel. A control rod is rotatably connected inside the intermediate column. A lower cone wheel and an upper cone wheel are respectively fixedly connected to the outer wall of the control rod. The lower cone wheel and the upper cone wheel are located between the adjustment cone wheel and the tightening cone wheel and do not mesh with each other in the original state.

[0012] Among them, a horn-shaped hole is opened at the bottom of the middle column. A plurality of inner sliding frames are slidably connected in the horn-shaped hole. One end of the inner sliding frame is rotatably connected with a moving ball. The bottom of the control rod is fixedly connected with a drooping rod. The end of the drooping rod is fixedly connected with a bucket-shaped block. The bucket-shaped block is located between the inner sliding frames and is used to extrude the inner sliding frames outwards.

[0013] Among them, a telescopic hanging rod is fixedly connected to the bottom of the horn-shaped hole. A parallel groove is fixedly opened at the top of the inner sliding frame. The end of the telescopic hanging rod is located in the parallel groove and the two are slidably connected.

[0014] Among them, an original hole is opened on one side of the middle column, and an upper hole and a lower hole are opened on the other side. A fixed rotating sleeve is rotatably connected outside the control rod. Intermediate holes are opened on both sides of the fixed rotating sleeve. A positioning rod is inserted into the original hole and the intermediate hole in the original state.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When the present invention is used, the middle column is placed at the central position of the four bases to be poured. Then, through the synchronous elongation of multiple groups of adjusting telescopic rods, the right-angle frame is sent to the required position of each corner base. The flip frame is rotated and turned down to be butted with the right-angle frame to form a square frame, and the flip frame and the right-angle frame are fastened together. At this time, pouring is carried out into the flip frame and the right-angle frame to form the base. By positioning the middle column at the central position of the four bases, the scribing and adjusting work before the base pouring can be reduced. The four corners move synchronously to reach, reducing a lot of intermediate work, improving the erection and installation efficiency of the photovoltaic panel, and improving the positioning accuracy of the base, avoiding large deviations between the bases resulting in installation stress or inability to install in subsequent bracket installation.

[0017] After the right-angle frame reaches the specified position, by rotating the inner nut sleeve, the threaded ring moves along the inner nut sleeve towards the middle column. Through the movement of the threaded ring to pull the tension rod, the flip frame is first automatically flipped and then locked, reducing the operation steps, improving the mold closing efficiency, and the mold closing is firm and reliable. Moreover, when demolding, reverse operation can first loosen the flip frame and then rotate to open the flip frame to achieve automatic flip demolding, reducing the operation difficulty.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-9, the present invention provides a technical solution:

[0033] A photovoltaic panel foundation pouring auxiliary kit structure includes an intermediate column 1 and multiple right-angle frames 2. The top of the right-angle frame 2 is rotatably connected to a flip frame 3 through a rotating shaft. The intermediate column 1 is circumferentially connected with multiple groups of adjusting telescopic rods 4 and extending telescopic rods 5. One group of adjusting telescopic rods 4 and extending telescopic rods 5 are rotatably connected at each right angle of the right-angle frame 2. The extending telescopic rod 5 is located above the adjusting telescopic rod 4. Tightening rods 6 are slidably connected to both sides of the right-angle frame 2. One end of each tightening rod 6 is rotatably connected to a fastening connecting rod 7, and the other end is fixedly connected to a tightening piece 8. The ends of the fastening connecting rods 7 are commonly connected to a threaded ring 9. The threaded ring 9 is internally threaded with an internal screw sleeve 10. The internal screw sleeve 10 is rotatably connected to the outside of the right-angle frame 2. Outer extending pressing pieces 11 are fixedly connected to the sides of the flip frame 3. The tightening rods 6 act on the outer extending pressing pieces 11 to buckle the flip frame 3 on the side of the right-angle frame 2 and form a square. The rotating shafts of the right-angle frame 2 and the flip frame 3 extend outward and the ends are fixedly connected to flip gears 12. A vertical rack 13 is slidably connected to the side of the right-angle frame 2. The vertical rack 13 meshes with the flip gear 12. A wedge-shaped block 14 is fixedly connected below the tightening rod 6. The wedge-shaped block 14 is located at the bottom of the vertical rack 13 and the two are slidably connected. The wedge-shaped block 14 is used to lift or pull down the vertical rack 13 when moving synchronously with the tightening rod 6 to drive the flip gear 12 to rotate, thereby making the flip frame 3 rotate to close or open.

[0034] Please refer to Figure 6 , when the present invention is used, the intermediate column 1 is placed at the center position of the four bases to be poured. Then, the right-angle frame 2 is sent to the required position at each corner base by synchronously extending multiple groups of adjusting telescopic rods 4. When the adjusting telescopic rods 4 extend, the extending telescopic rods 5 follow and extend together. After the right-angle frame 2 reaches the specified position, the flip frame 3 is rotated down to dock with the right-angle frame 2 to form a square frame, and the flip frame 3 and the right-angle frame 2 are fastened together. At this time, pouring is carried out into the flip frame 3 and the right-angle frame 2 to form the base. By positioning the center position of the four bases through the intermediate column 1, the scribing adjustment work before the base pouring can be reduced. It changes from originally needing to position each base position to only needing to position the position of one intermediate column 1. At the same time, the base spacing is determined so that the right-angle frame 2 extends to the specified spacing. The four corners move synchronously to reach, reducing a lot of intermediate work, improving the erection and installation efficiency of the photovoltaic panel, and improving the positioning accuracy of the base, avoiding large deviations between the bases resulting in installation stress or inability to install the subsequent brackets, etc.

[0035] Please refer to Figure 5 , 7, 8. After the right-angle frame 2 reaches the specified position, by rotating the inner sleeve 10, the threaded ring 9 moves along the inner sleeve 10 towards the middle column 1, and then the tightening link 7 is used to pull the tension rod 6 towards the right angle of the right-angle frame 2. When the tension rod 6 moves, the wedge block 14 fixedly connected to it moves together, and then the vertical rack 13 is jacked up and moved through the wedge surface. During the upward movement of the vertical rack 13, the flip gear 12 meshed with it rotates, and then the flip frame 3 rotates to flip. Since the tension piece 8 protrudes far beyond the edge of the right-angle frame 2 in the original state, the outward extending pressure piece 11 flips downward to reach above the tension rod 6 on the side of the right-angle frame 2 and is located outside the tension piece 8. After the flip frame 3 finishes flipping and forms a square frame with the right-angle frame 2, continue to rotate the inner sleeve 10. At this time, the tension rod 6 has moved to a position where the tension piece 8 is closer to the outward extending pressure piece 11. Continuing to rotate further pulls the tension rod 6 inward. Since the upper surface of the rear end of the wedge block 14 is a flat surface, the vertical rack 13 will not be moved during the subsequent movement. Therefore, the flip frame 3 remains in the flipped and closed state without moving, and the tension rod 6 continues to move inward, causing the tension piece 8 to gradually approach the outward extending pressure piece 11 and then tightly press the outward extending pressure piece 11, thereby applying force to the flip frame 3 to closely adhere to the right-angle frame 2, ensuring sealing and stability. After pressing the outward extending pressure piece 11, due to the self-locking performance of the threaded connection between the threaded ring 9 and the inner sleeve 10, the threaded ring 9 can be stopped at the position where the outward extending pressure piece 11 is pressed tightly at will without accidental loosening, ensuring the closing and stability of the right-angle frame 2 and the flip frame 3. By pulling the tension rod 6 through the movement of the threaded ring 9, the flip frame 3 is first automatically flipped and then locked, reducing the operation steps, improving the mold closing efficiency, and the mold closing is firm and reliable. During demolding, reverse operation can first loosen the flip frame 3 and then rotate to open the flip frame 3 to achieve automatic flip demolding, reducing the operation difficulty.

[0036] Among them, outer support plates 15 are fixedly connected to the outside of the right-angle frame 2. The tension rod 6 passes through the outer support plates 15 and is in sliding fit with them. A transfer seat 16 is fixedly connected to the inner side of the threaded ring 9. The tightening links 7 are located on both sides of the inner sleeve 10 and are rotationally connected to the transfer seat 16.

[0037] The movement direction of the tension rod 6 is limited by the outer support plates 15, so that it can only move horizontally, and then act on the outward extending pressure piece 11 to achieve pressing. The connection with the tightening link 7 is facilitated through the transfer seat 16. At the same time, the threaded ring 9 is limited to only translate and not rotate, which is convenient for the cooperation with the inner sleeve 10.

[0038] Among them, a side slide rail 17 is fixedly connected to the outside of the right-angle frame 2. One side of the vertical rack 13 is slidably connected within the side slide rail 17. A connection slideway 18 is opened at the top of the wedge block 14. A connection ball shaft is fixedly connected to the bottom of the vertical rack 13, and the connection ball shaft is located within the connection slideway 18 and is in sliding connection with it.

[0039] When the wedge block 14 moves, the wedge block 14 and the vertical rack 13 are connected together through the connecting ball shaft and the connecting slideway 18. When the vertical rack 13 falls back to its original position, it can be firmly pulled back to avoid disconnection between the two, making the movement reliable and ensuring that the flip frame 3 can rotate smoothly to open the flip.

[0040] Please refer to Figures 2-3 Figures 7-8, in which the adjusting telescopic rod 4 includes a fixed outer cylinder 19, an inner rod 20 and an intermediate square rod 21. The fixed outer cylinder 19 is fixedly connected to the side wall of the intermediate column 1, the inner rod 20 is rotatably connected to the outside of the right-angle frame 2, the intermediate square rod 21 is slidably connected to the middle of the inner rod 20. The inner rod 20 is threadedly connected inside the fixed outer cylinder 19, and the intermediate square rod 21 is completely sleeved in the middle of the fixed outer cylinder 19. The extended telescopic rod 5 has the same structure as the adjusting telescopic rod 4, but the inner rod 20 of the extended telescopic rod 5 is a smooth rod and a tightening gear 40 is fixedly connected to the outer wall. The tightening gear 40 meshes with the outer ring of the internal thread sleeve 10.

[0041] The elongation of the adjusting telescopic rod 4 can be achieved by rotating the intermediate square rod 21 to drive the inner rod 20 to rotate. Thus, through the threaded fit between the inner rod 20 and the fixed outer cylinder 19, the adjusting telescopic rod 4 elongates to extend the right-angle frame 1 outward to the specified position. When the adjusting telescopic rod 4 elongates, the extended telescopic rod 5 elongates together. The inner rod 20 of the extended telescopic rod 5 directly slides outwards to adapt to the outward extension movement of the right-angle frame 2, and at the same time ensures that the tightening gear 40 and the internal thread sleeve 10 are always in a meshed state, thus facilitating subsequent simplified operations. By rotating the intermediate square rod 21 of the extended telescopic rod 5, the inner rod 20 inside it can be driven to rotate and then drive the tightening gear 40 to rotate, and the internal thread sleeve 10 is rotated through gear meshing, which is convenient for the outward extension of the right-angle frame 2 and the flipping and locking of the flip frame 3 to be concentrated in the intermediate column 1.

[0042] Please refer to Figures 2-3 Figures 9, in which the inner ends of the intermediate square rods 21 of the adjusting telescopic rod 4 and the extended telescopic rod 5 are respectively fixedly connected with an adjusting cone wheel 22 and a tensioning cone wheel 23. A control rod 24 is rotatably connected inside the intermediate column 1. An upper cone wheel 26 and a lower cone wheel 25 are respectively fixedly connected to the outer wall of the control rod 24. The lower cone wheel 25 and the upper cone wheel 26 are located between the adjusting cone wheel 22 and the tensioning cone wheel 23 and do not mesh with each other in the original state.

[0043] Specifically, by moving the control rod 24 downward, the adjusting cone wheel 22 can be made to mesh with the lower cone wheel 25 first. At this time, by rotating the control rod 24, the adjusting cone wheel 22 can be driven to rotate by the lower cone wheel 25, and then the intermediate square rod 21 of the adjusting telescopic rod 4 can be driven to rotate, and then the inner rod 20 can be driven to rotate inside the fixed outer cylinder 19. Through the threaded fit between the two, the inner rod 20 gradually extends out, the adjusting telescopic rod 4 gradually becomes longer, and the right-angle frame 2 is extended outward to the specified position, and the four corners are synchronized, and the movement is accurate and reliable;

[0044] Then lift the joystick 24 upward again, so that the adjustment cone pulley 22 disengages from the lower cone pulley 25, and the tensioning cone pulley 23 meshes with the upper cone pulley 26. By rotating the joystick 24, the middle square rod 21 of the extension telescopic rod 5 is rotated, and then the inner rod 20 is rotated together, and the tightening gear 40 outside the inner rod 20 is rotated. By rotating the tightening gear 40, the inner nut sleeve 10 is rotated, and then the movement of the threaded ring 9 is driven by the rotation of the inner nut sleeve 10 to realize the actions of first closing and then locking the flip frame 3. Thus, through the joystick 24 of the middle column 1, the remote control of the outward movement of the right-angle frame 2, the rotation and locking of the flip frame 3 can be realized, and at the same time, the movement and control of the right-angle frame 2 and the flip frame 3 at the four corners can be carried out. There is no need to adjust and lock each corner one by one, which greatly improves the positioning efficiency, and the positioning is accurate and evenly distributed, which is beneficial to the erection and installation of the photovoltaic frame.

[0045] Please refer to Figure 9 , in which, a horn-shaped hole 27 is opened at the bottom of the middle column 1, and a plurality of inner sliding frames 28 are slidably connected in the horn-shaped hole 27. One end of the inner sliding frame 28 is rotatably connected with a moving ball 29. The bottom of the joystick 24 is fixedly connected with a drooping rod 30, and the end of the drooping rod 30 is fixedly connected with a bucket-shaped block 31. The bucket-shaped block 31 is located between the inner sliding frames 28 and is used to extrude the inner sliding frames 28 outward.

[0046] In order to avoid the friction between the right-angle frame 2 and the ground when moving outward, resulting in difficult movement, when the joystick 24 moves downward and is about to make the adjustment telescopic rod 4 extend to send out the right-angle frame 2, the drooping rod 30 moves downward together. Then, through the bucket-shaped block 31 at the bottom, the surrounding inner sliding frames 28 are extruded outward. Under the action of the inner inclined side of the horn-shaped hole 27, the inner sliding frames 28 move outward and then jack up the middle column 1 by a certain distance, so that the moving ball 29 touches the ground and the middle column 1 leaves the ground, and the right-angle frame 2 is also driven to move upward and leave the ground. At this time, the joystick 24 can be continuously rotated to make the adjustment telescopic rod 4 extend to move the right-angle frame 2 outward, and the right-angle frame 2 will not be dragged and moved, greatly reducing the moving resistance of the right-angle frame 2, facilitating the movement of the right-angle frame 2 and reducing wear. At the same time, when landing, it can ensure to be in contact with the ground, extending the service life.

[0047] At this time, the position of the middle column 1 can also be pushed to move the middle column 1, which is more convenient and labor-saving.

[0048] Among them, a telescopic suspension rod 32 is fixedly connected to the bottom of the horn-shaped hole 27, and a parallel groove 33 is fixedly opened at the top of the inner sliding frame 28. The end of the telescopic suspension rod 32 is located in the parallel groove 33 and the two are slidably connected.

[0049] The telescopic suspension rod 32 keeps the inner sliding frame 28 in a horizontal state, so that it can effectively move outward in parallel. When the inner sliding frame 28 moves outward, the telescopic suspension rod 32 lengthens accordingly to adapt to the movement of the inner sliding frame 28.

[0050] Please refer to Figure 3 , wherein, an original hole 34 is provided on one side of the middle column 1, and an upper hole 35 and a lower hole 36 are provided on the other side. A fixed rotating sleeve 37 is rotatably connected outside the control lever 24. Middle holes 38 are provided on both sides of the fixed rotating sleeve 37. A positioning rod 39 is inserted into the original hole 34 and the middle hole 38 in the original state.

[0051] Before using the control lever 24, first pull out the positioning rod 39. When the control lever 24 is moved downward to push out the inner sliding frame 28 and make the adjusting cone pulley 22 engage with the lower cone pulley 25, the middle hole 38 of the fixed rotating sleeve 37 of the control lever 24 is aligned with the upper hole 35. At this time, reinsert the positioning rod 39 to keep the control lever 24 in the current state, keep the inner sliding frame 28 in the extended state, and keep the adjusting cone pulley 22 and the lower cone pulley 25 in the engaged state, so as to prevent the middle column 1 from falling back under its own weight, etc.;

[0052] When the control lever 24 is lifted upward and the tensioning cone pulley 23 engages with the upper cone pulley 26, the lower hole 36 is aligned with the middle hole, and the positioning rod 39 is inserted through, so as to keep the tensioning cone pulley 23 and the upper cone pulley 26 in the engaged state. When rotating the control lever 24, there is no need to continuously lift the control lever 24, just rotate it, which is more labor-saving.
