Description

Technical Field

[0001] The present invention relates to a method for outdoor assembly of an array of solar converters (e.g., photovoltaic solar panels or solar mirrors). Background Technology

[0002] In document WO 2019 / 097348 A1, the applicant has proposed a method and system for the outdoor assembly of an array of photovoltaic solar panels, wherein a frame for supporting the photovoltaic solar panels is pre-assembled in an open area, and then the photovoltaic solar panels are installed on the support frame by a robot mounted on a vehicle moving on the assembly site. The robot positions the photovoltaic solar panels on continuous portions of the aforementioned support frame. The main advantage of this solution is that the assembly of the photovoltaic solar panels can be performed in a fully automated manner. The vehicle carrying the robot can be, for example, an automated guided vehicle (AGV) or a remotely controlled vehicle. Associated with the robot is an observation system, which the robot's control system uses to properly position the photovoltaic solar panels, although the position of the vehicle relative to the support frame is variable due to terrain irregularities.

[0003] Of course, the aforementioned known solutions involve the relative complexity of the system and may not be suitable when the goal is to reduce the cost of assembling the system as much as possible.

[0004] To overcome the aforementioned drawbacks, the applicant has proposed a method for assembling and mounting an array of solar converters, such as photovoltaic panels or even solar mirrors, in its Italian patent application IT 10 2020 000010507 (which remains confidential at the priority date of this invention). The method includes:

[0005] a) The first step of assembling the array of solar converters is carried out in a mobile workstation (as a “temporary factory”) temporarily located near the assembly site, with the assistance of at least one robot.

[0006] b) A second step of transporting the array of solar converters assembled in the first step, wherein the assembled array of solar converters is transported from the aforementioned workstation to the assembly location with the aid of a carrier; and

[0007] c) The third step of assembling the array of solar converters, wherein the array of solar converters is mounted on a row of support columns pre-arranged in the assembly site.

[0008] The aforementioned first assembly step includes assembling the support frame of the solar converter and mounting the solar converter onto the support frame.

[0009] This invention is derived from existing proposals and relates to the configuration and usage methods of a carrier specifically for the transport and assembly of arrays of solar converters.

[0010] Document WO 2014 / 108196 A1 describes a technique for assembling arrays of photovoltaic solar panels in an open field, using vehicles, particularly semi-trailer trucks, capable of transporting containers containing one or more arrays of photovoltaic solar panels. The truck is equipped with a front crane and a rear crane, which are used to grab the container initially located on the ground and load it onto the truck's platform or keep the container in the air. Furthermore, the truck is equipped with a lifting arm capable of grabbing the array of photovoltaic solar panels contained in the container, lifting the array of photovoltaic solar panels to remove it from the container, and laying the array of photovoltaic solar panels on a support structure pre-arranged in the field. Clearly, this solution is very complex and expensive, and not particularly efficient. First, semi-trailer trucks, even just because of their size, are far from being conveniently located at assembly sites, which are often situated in rugged terrain. Furthermore, the obstruction of the containers prevents the truck from positioning itself near the support structure for receiving the array of photovoltaic solar panels. To overcome this drawback, during assembly operations, a crane mounted on the truck holds the container in a high, raised position above the truck, but this, of course, requires a lot of energy and poses considerable safety concerns for the operator. Summary of the Invention

[0011] The purpose of this invention is to further improve upon the applicant's existing proposals, particularly regarding the final steps of picking up, transporting, and assembling arrays of solar converters at an assembly site.

[0012] In particular, another objective of the present invention is to make the final assembly operation simpler and faster, and to make it more reliable in ensuring the correct positioning of the solar converter array in the site.

[0013] Another objective of this invention is to significantly reduce the cost of assembly operations.

[0014] To achieve the foregoing objectives, the subject of this invention is a method for the outdoor assembly of an array of solar converters (e.g., photovoltaic solar panels or solar mirrors), characterized by the following features: the array of solar converters includes a support frame and a plurality of solar converters mounted on the support frame; the support frame is laid on a support structure, the support structure including a series of aligned support columns arranged in an assembly site; a vehicle is provided for transporting the array of solar converters and for laying the array of solar converters on the support structure; the vehicle is equipped with a lifting device for shifting the array of solar converters between a raised position and a lowered position, thereby maintaining the overall plane of the array having a substantially horizontal orientation until the array of solar converters is laid on the support structure; the method is characterized in that the support frame of the array of solar converters includes a series of aligned support columns arranged in an assembly site. The vehicle is a carrier, comprising a load-bearing structure mounted on wheels and a main superstructure pre-arranged to receive an array of solar converters thereon. A lifting device is positioned between the load-bearing structure and the main superstructure. The array of solar converters is mounted on the main superstructure. Associated with the carrier is an electronic control unit for controlling the movement of the carrier and driving the lifting device. The electronic control unit is configured to perform the following steps: stopping the carrier at a row of support columns in an adjacent assembly area; raising the array of solar converters above the support columns; displacing the carrier within the space between two successive columns in the row; and lowering the array of solar converters until the longitudinal beams of the support frame of the array of solar converters are laid on the support columns of the row.

[0015] In a preferred embodiment, a first lifter and a second lifter are arranged on the carrier at positions spaced apart from each other along the longitudinal direction of the carrier, and the electronic control unit is programmed to control the two lifters (in a differentiated manner if necessary) to tilt the array of solar converters longitudinally (i.e., along the longitudinal direction of the carrier) forward or backward according to the possible corresponding tilt in the terrain.

[0016] A first and a second lifter are positioned between a base structure and the main superstructure, the base structure being fixed to the load-bearing structure of the carrier, the main superstructure bearing the weight of the solar converter array. In one embodiment, associated with the aforementioned superstructure is an auxiliary support structure for supporting the solar converter array, and this auxiliary support structure is mounted such that it can swing about a longitudinal central axis on the main superstructure. An actuator is provided that controls the rotation of the auxiliary support structure about the longitudinal central axis, in such a way that the lateral tilt of the solar converter array is controlled according to the contours of the terrain in the assembly area.

[0017] Due to the aforementioned features, in the above example of the embodiment, the overall plane of the solar converter array can therefore perform pitching oscillations that tilt forward or backward, and rolling oscillations that tilt to one side or the other. In this way, during the laying operation, the solar converter array can be oriented in a way that allows for taking into account the terrain's tilt in the longitudinal direction of the support column row and in the direction transverse to the longitudinal direction.

[0018] Again, in the preferred embodiment, the aforementioned superstructure includes a first superstructure portion connected to the lifting device and a second superstructure portion that directly or indirectly carries the array of solar converters, and is longitudinally translatable to apply limited longitudinal movement over the array of solar converters. During the final assembly stage, this movement is used to connect the longitudinal beams of the support frame of the array of solar converters carried by the carrier to the longitudinal beams of the frame of the array of solar converters previously laid on support columns in the assembly site.

[0019] According to another feature, the upper structure supported by the lifting device directly or indirectly supports multiple clamping devices, which are longitudinally arranged at a certain distance from each other to receive and block the longitudinal beams of the support frame of the solar converter array.

[0020] In a preferred embodiment, each clamping device includes a receiving section and a pair of blocking elements in which the longitudinal beams of the solar converter array frame are received. The pair of blocking elements are displaceable between an open, released position and a closed, blocked position. Preferably, the two blocking elements have a loosely blocked intermediate position where the beams received in the receiving section are prevented from dislodging, but in any case, a certain gap exists within the receiving section. During the final assembly stage, the clamping devices are pre-arranged under the aforementioned loosely blocked condition to allow the solar converter array frame to freely perform minor adjustment movements.

[0021] According to further features, during transport on the carrier, the last row of solar converters, which cantilevered over the longitudinal beams of the supporting frame, were temporarily supported by auxiliary tools associated with the longitudinal beams of the frame.

[0022] The carrier can be constructed in any known manner. However, in a preferred solution, the aforementioned load-bearing structure is mounted on wheels capable of orientation about a vertical axis, thereby enabling the carrier to move forward or backward in a direction parallel to its longitudinal direction, to turn relative to that longitudinal direction, and to translate in a direction orthogonal to that longitudinal direction. In this way, the carrier can move along a row of support columns in the assembly site and then translate laterally to position itself in the space between two continuous columns on which the array of solar converters carried by the carrier will be laid.

[0023] In the aforementioned example, the carrier can be configured according to so-called AGV (Automated Guided Vehicle) or AMR (Automated Mobile Robot) technology, having electric motors for controlling the orientation of the wheels and electric motors for traction on the wheels. Furthermore, a battery is envisioned to power the electric motors and electric actuators of the lifting device. Attached Figure Description

[0036] Figures 16 and 17 are front and perspective views, respectively, of the auxiliary tools associated with the longitudinal beams of the support frame. Detailed Implementation

[0037] The following is in conjunction with the accompanying drawings. Figures 1 to 3 In the accompanying drawings, reference numeral 1 generally indicates an array of solar converters (in a specific example, photovoltaic solar panels P). The invention can also be applied to arrays of different types of solar converters, such as arrays of solar mirrors.

[0038] In the example shown, the array 1 of photovoltaic solar panels P has a generally planar structure, with a supporting frame 2 to which the panels P are fixed. In this example, the frame 2 includes longitudinal beams 3 and multiple transverse members 4. Again, in the example shown, the array 1 includes two rows of panels P arranged side by side. Each panel is fixed to the longitudinal beams 3 and two transverse members 4. Again, in the example shown, only the two panels P at the right end of the array (as shown) Figure 1 Each of the observed components has a first side fixed to the beam 3, a second side fixed to the transverse member 4, and a third side opposite to the second side, which protrudes from the transverse member 3 in a cantilever manner.

[0039] Frame 2 and panel P are assembled together in an assembly station (not shown) near the assembly site to form array 1 (preferably using the method shown in the prior patent application IT 10 2020 000010507 filed by the applicant).

[0040] Once assembled, the array 1 of panel P is transported to the assembly location by means of a carrier 5, which supports the frame 2 for supporting the array 1 by means of a lifting device 6. The array 1 of panel P can be vertically moved via the lifting device. Figure 1 As can be seen, the lifting device 6 maintains the overall plane of the array 1 with a basically horizontal orientation, but as will be described below, the lifting device can also tilt the array 1 forward or backward in the longitudinal direction of the carrier 5, and the lifting device can also tilt the array laterally on one side or the other side, so that when the array 1 is laid in the assembly site, its orientation is best suited to the local terrain slope.

[0041] The vehicle 5 can be constructed using any known technology, such as technology commonly used in AGV or AMR type vehicles.

[0042] In one example, the carrier 5 has a load support structure 50 mounted on wheels R, each wheel being oriented about a vertical axis, allowing the carrier to translate forward or backward in a direction parallel to its longitudinal direction, to turn relative to the longitudinal direction, and to translate laterally relative to the aforementioned longitudinal direction by means of a 90° rotation of the wheels about the corresponding vertical oriented axis. The load support structure 50 carries an electric motor for orienting the wheels about the corresponding vertical oscillation axis and an electric motor for traction on the wheels.

[0043] All the aforementioned construction details are not shown in this document, provided that they can be implemented in any known manner. In the drawings, the wheel R is represented as a conventional wheel merely for ease of representation.

[0044] In addition, Figure 2 The diagram schematically illustrates an electronic control unit E and an electric power supply battery B, which are pre-arranged on the load support structure 50 of the carrier 5. The electronic control unit E is configured and programmed to control the electric motor on the carrier 5 to move the carrier according to a preset path, and to control the electric actuator (described below) that controls the lifting device 6. The electronic control unit E on the carrier 5 preferably communicates wirelessly with the drive unit A (see diagram). Figure 1 Communication is possible, for example, with the drive unit controlled by operator O, who is positioned close to the carrier 5. This mode of use is, of course, merely illustrated here. The drive unit A can also be controlled by an operator from a control tower, or, again, for example, the carrier 5 can be moved around the assembly site using a tractor.

[0045] refer to Figure 2The lifting device 6 includes a first lifter 6A and a second lifter 6B, which are spaced apart from each other in the longitudinal direction of the carrier 5. In this example, lifters 6A and 6B are telescopic. They will be described in detail below.

[0046] Using two lifters 6A and 6B, which are longitudinally positioned at a certain distance from each other, allows for differentiated operation of lifters 6A and 6B, resulting in the pitch swing of array 1 of panel P. In other words, the overall plane of array 1 can be tilted longitudinally forward or backward. Considering the construction of the terrain on which array 1 of panel P will be positioned, this feature is useful for orienting the overall plane of array 1 in the most appropriate manner.

[0047] Figure 4 and Figure 5 This is a top plan view showing the final step in positioning the array 1 of panel P at the assembly site.

[0048] In the assembly area, multiple rows of support columns 7 are pre-arranged, with the support columns spaced a certain distance apart longitudinally. Figure 4 and Figure 5 A row of support columns 7 is shown, wherein an array 1' of panel P is pre-positioned, and longitudinal support beams 3 of the array are connected to the support columns 7.

[0049] Figure 4 A step is shown in which the carrier 5 moves laterally relative to its longitudinal direction because the orientation of the carrier's wheels R is rotated by 90° relative to the normal orientation of its longitudinal movement. Figure 5 The final position reached by the carrier 5 is shown, where the carrier 5 enters the space between two adjacent columns 7. The distance between the columns 7 in the assembly site and the length of the carrier 5 in its longitudinal direction are chosen such that the carrier 5 can insert itself into the space between the two successive columns 7.

[0050] exist Figure 4 and Figure 5 During the approaching movement shown, the lifting device 6 of the carrier 5 (including lifts 6A and 6B) remains in the raised position, as... Figure 2 As shown, this is to ensure that the plane of array 1 of panel P is located on support column 7.

[0051] Once you arrive Figure 5 At the position shown, that is, the position where the support beam 3 of array 1 of panel P in the top plan view is aligned with a row of support columns 7, the operator drives the lifts 6A and 6B to descend until the support beam 3 of array 1 is laid on the support columns 7 located below.

[0052] According to known technology, the support beams 3 of each array of panels are received within a receiving portion defined by connecting members carried at the top of support columns 7. These connecting members have a first portion that receives the support beam 3 and is hinged to a second portion that is anchored to the top of the corresponding support column, thereby allowing the support beam 3 to swing about an axis parallel to its longitudinal direction. Again, according to known technology, the swinging movement can be controlled by any type of actuator device to provide a means for tracking the apparent motion of the sun during the day. In this way, when using a solar converter system, each array 1 of panel P gradually swings about an axis parallel to its longitudinal support beam 3.

[0053] The foregoing details regarding solar tracking devices will not be described herein, as they can be obtained in any known manner and are not themselves within the scope of this invention.

[0054] In the preferred embodiment shown herein, the lifters 6A and 6B constituting the lifting device 6 have... Figure 6 , 7 The structure is more clearly visible in 8.

[0055] First refer to Figure 6 The lifting device 6 includes a base structure 8 and an upper structure 9 (in Figure 6 and Figure 7 (Illustrated schematically) The base structure is fixed to the load support structure 50 of the carrier 5, and the upper structure can be vertically moved relative to the base structure 8 by means of lifters 6A and 6B.

[0056] In the example shown, both lifts 6A and 6B consist of two telescopic lifts. (See also: Special Reference) Figure 8 Lifters 6A and 6B each have a pair of main arms 81A and 81B, each having a bottom end and a top end. The bottom ends are hinged to the lower structure 8 about fixed transverse axes 80A and 80B, and the top ends are mounted such that they can slide within longitudinal guides 90 of the upper structure 9. Furthermore, lifters 6A and 6B each include two auxiliary arms 82A and 82B (see also...) Figure 8 The auxiliary arm has a top end and a bottom end, the top end being hinged to the middle portion of arms 81A and 81B, and the bottom end being mounted such that they can slide within the longitudinal guide 80 of the base structure 8. Associated with the two lifters 6A and 6B are two pairs of electrically driven cylinder actuators 83A and 83B (see...). Figure 8 The electrically driven cylinder actuator is operably positioned between the base structure 8 and arms 81A and 81B.

[0057] Activation of actuators 83A and 83B enables control over the height position of the upper structure 9 relative to the lower structure 8.

[0058] As described above, the electronic control unit is pre-arranged to enable differentiated actuation of actuators 83A and 83B, allowing the tips of arms 81A and 81B to be positioned at different heights. Therefore, the upper structure 9 can tilt longitudinally forward or backward (i.e., as...). Figure 6 As shown, to the left or right, so that the array 1 of panels P carried by the lifting device 6 has a corresponding tilt. In this way, due to the tilt of the terrain in the longitudinal direction of the support column row, the array 1 of panels can be adapted to be laid on support columns set at different heights.

[0059] Refer again Figure 8 In the illustrated embodiment, the superstructure 9 is in the form of a quadrilateral frame with two longitudinal beams L, the ends of which are connected together by a transverse member T. This structure allows for limited longitudinal movement relative to the guide 90, where the tops of the arms 81A and 81B of the two lifters 6A and 6B can slide within the guide. This limited longitudinal movement is controlled by two electrically driven cylinder actuators 91. Due to this feature, once the lifting device 6 has laid the array 1 of panels P onto the support column 7 and the support beams 3 of the array 1 have been inserted into the receiving portion provided at the top of the column, the actuators 91 can be driven to slightly move the entire array 1 longitudinally relative to the carrier 5 carrying the array. This is necessary to connect one end of the longitudinal support beam 3 to the corresponding end of the support beam of the adjacent array 1 of panels P that has been previously laid in the assembly area.

[0060] Refer again Figure 8 and Figure 9 The two end transverse members T of the upper structure 9 support two longitudinal pins 10, which have an auxiliary support structure 12 that swings around the longitudinal central axis 11. Figure 9 The auxiliary support structure 12 directly supports the array 1 of panels P. The rotation of the auxiliary support structure 12 about the longitudinal central axis 11 can be achieved by means of the actuator 13 carried by the upper structure 9. Figure 8 To control it.

[0061] Figure 10 A perspective view of the carrier 5 is shown (for ease of illustration, the wheels R are shown as conventional wheels), with the lifting device 6 shown in a lowered state. Figure 10 A partially cutaway auxiliary support structure 12 is shown. This structure includes two longitudinal beams L1, each having ends connected by two transverse members T1. Each transverse member T1 (one of the transverse members is in...) Figure 10(Partially cut open) has a central portion 14 that arches downward relative to the end of the transverse member T1, so as not to interfere with the area receiving the longitudinal beam 3 of the array 1 for supporting the panel P.

[0062] The longitudinal beams 3 of the frame for supporting the array 1 of panels will be received in the receiving portion of a plurality of clamping devices 15 (three clamping devices 15 are provided in the example shown) carried by a transverse member 150, the transverse member having ends that are connected to the two longitudinal beams L1.

[0063] Figure 13-1 Figure 5 shows the clamping device 15 at an enlarged scale. The structure of the transverse member 150 defines a receiving portion 151 for receiving the support beam 3 of the array 1 of receiving panels P. The receiving portion has a bottom wall and two side walls defined by two plates 153. Once the longitudinal beam 3 is received within the receiving portion 151, the longitudinal beam can be blocked in this position by means of two blocking elements 152, which can be displaced between an operating blocking position and an open release position (not shown). The movement of the two blocking elements 152 is controlled by means of a corresponding actuator (not shown) of any known type.

[0064] In the carrier according to the invention, the clamping device 15 carried by the lifting device 6 is used when the array 1 of the panels P is loaded onto the carrier 5 in the workstation for assembly of the array of panels, and during the process of laying the array of panels in the assembly site.

[0065] During the loading of the panel array 1 onto the carrier 5 (not shown in the accompanying drawings), the carrier positions itself below the assembled array, and the lifting device is driven to raise the upper structure 9, along with the auxiliary support structure 12, thereby keeping the clamping device 15 in the open state. In this way, after the upper structure 9 is raised by the lifting device, the longitudinal beams 3 of the support frame of the panel array are received within the receiving portion of the clamping device 15. Once the beams 3 supporting the panel array are received within the support 151 of the clamping device, the clamping device is activated to hold the beams 3 against the structure 12. Therefore, the lifting device can be lowered, and the carrier can be driven to bring the panel array to the assembly location.

[0066] Once we arrive at the assembly location, the above has already been referenced. Figure 4 and Figure 5 The described steps will be activated so that the longitudinal beam 3 of the support frame of the panel array is positioned on the receiving part set at the top of the support column 7 in the assembly site.

[0067] In this step, if necessary, the possibility of orienting the auxiliary support structure 12 around the longitudinal axis 11 allows the overall plane of the panel array to be laterally tilted on one side or the other, thereby generating a rolling rotation thereon. Figure 9 ( ), so as to take into account the possible tilt of the terrain in the direction transverse to the longitudinal direction of the support column 7.

[0068] Once the longitudinal beam 3 of the support frame of the panel array is received in the receiving part provided at the top of the support column, the actuator 91 will be activated. Figure 8 This allows for a slight longitudinal movement across the entire array of panels, necessary to connect one end of the longitudinal beam 3 of the array to the corresponding end of the longitudinal beam of the support frame of the adjacent array of panels previously laid in the assembly area. Once the connection between the longitudinal beams is complete (e.g., with operator intervention), the longitudinal beam 3 can be stopped in the receiving part of the connecting device provided at the top of the support column 7.

[0069] According to a preferred feature, the clamping device 13 allows the blocking element 152 to be positioned in an intermediate position between the open position and the clamping position, in which the beam 3 is loosely blocked. In this configuration, the beam 3 is prevented from dislodging from the receiving part 151, but a limited gap is provided within the receiving part, which allows for minor adjustment movements during operation of the connecting device provided at the top of the support column 7 to connect the beam 3.

[0070] Once the connection is complete (e.g., by manual operation), the clamping device 15 can be fully opened, and the lifting device 6 can be lowered to completely release the carrier from the array 1 of panels laid in the assembly area.

[0071] Figures 16 and 17 show an auxiliary tool associated with the longitudinal beams 3 of the support frame of the panel array 1 to support the last row of panels in the array during transport.

[0072] refer to Figure 1The two end panels of the array (the right-hand end in the figure) cantilever over the ends of the longitudinal support beam 3. Therefore, unlike the other panels, they are not supported on opposite sides by two transverse members 4. To reliably support these panels during transport, an auxiliary member, shown in Figures 16 and 17 and indicated by reference numeral 16, is mounted on the transverse member 3. This member consists of a transverse bar 163 (in the example with a circular cross-section), which has a clamp 160 at its center, clamping it to one end of the transverse member 3. In the example shown, the clamp 160 includes two manually driven toggle-type gripping devices 161, but of course any gripping device can be used for this purpose. The bar 16 serves as further support for the two end panels P of the array, and the bar also has two additional manually driven gripping devices 162 at its ends, which are also, for example, toggle-type, for holding the panels P against the bar 16.

[0073] The configuration of the support frame for the solar converter array may also differ from the configuration shown as an example herein. Furthermore, in this specification and the following claims, the term "longitudinal beam" should generally be understood to include cases where one or more beam elements do not extend through the length of the solar converter array.

[0074] Similarly, the description of the overall plane of the solar converter array as "basically horizontally oriented" should be broadly understood to define an orientation significantly different from vertical orientation in any case. As previously mentioned, the overall plane of the array can be tilted longitudinally and laterally relative to a horizontal arrangement, depending on the contours of the terrain in the assembly area. For the same reason, the movement of the lifting device may occur in a direction other than vertical.

[0075] In the example shown here, the support column 7, pre-arranged in the assembly area, is high enough to receive the array 1 on it as the lifters 6A and 6B of the carrier 5 descend. If the support column 7 is too low to achieve this mode of operation, it is conceivable that the lifters 6A and 6B would lay the array 1 on higher auxiliary columns, such as those with telescopic structures, pre-arranged in the assembly area. Once the carrier is released from the array 1, after the array has been laid on the aforementioned auxiliary columns, these auxiliary columns are shortened to lay the array 1 on shorter main columns.

[0076] Naturally, without prejudice to the principles of the invention, the details of the construction and embodiments may vary extensively relative to what is described and shown herein purely by way of example, without departing from the scope of the invention as defined in the claims.
