Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module processing, and more specifically, to a device for processing an offshore photovoltaic module support structure. Background Art

[0002] Photovoltaic modules are composed of solar cells that convert solar energy directly into electrical energy through the photovoltaic effect. Photovoltaic modules are usually composed of multiple solar cells arranged together and use specific electrical and structural designs to achieve high efficiency and long-term stability. Photovoltaic modules mainly include: solar cells, cell encapsulation layers, support structures, connecting wires and junction boxes, etc. Among them, the support structure is used to support the solar cells so that they can stably face the sun and generate electricity. Especially in offshore photovoltaic modules, in order to ensure the stable power generation of solar panels, a safer and more stable support system is required.

[0003] The supporting structure includes pile foundations, pillars and a large number of bracket structures. Before production, the corresponding bracket structure will be welded and processed according to site requirements, and then assembled during the construction of the photovoltaic power plant. In order to ensure strong support for solar panels, most of the structures in the bracket are made of steel structures. In order to facilitate assembly, corresponding holes or other docking structures will be set in some areas of the bracket to facilitate the use of bolts or other fasteners to install and support the bracket and solar panels and other structures.

[0004] As offshore space utilization is more efficient than on land, offshore photovoltaic modules have developed rapidly in recent years. Offshore photovoltaic systems can be deployed on a large scale on the ocean surface, effectively utilizing vast sea areas, and are particularly suitable for coastal areas and islands.

[0005] However, due to the complexity of the marine environment, factors such as salt, moisture, and sea breeze in seawater can cause corrosion and damage to photovoltaic modules and supporting structures. Therefore, offshore photovoltaic modules, especially support structures that are more likely to come into contact with seawater, need to have good corrosion resistance. Therefore, compared with photovoltaic modules on land, the support structure of offshore photovoltaic modules also needs to be coated with an anti-corrosion coating on the surface of the support during production to enhance its durability in the seawater environment, thereby ensuring the life of the offshore photovoltaic modules.

[0006] At the same time, in order to ensure the adhesion strength between the coating and the bracket material, the bracket surface needs to be polished before applying the coating to remove the rust layer and other covering layers on the bracket surface, and keep a certain roughness on the bracket surface, so as to improve the bonding strength of the coating.

[0007] Since the connection between each bracket structure and other structures requires the use of hole structure and bolt structure for installation, some brackets will involve more holes. Since the steel structure in the bracket structure is mostly hollow and the inner wall is not easy to coat, such holes provide the possibility for the internal and external connection of the bracket. That is to say, after the bracket is assembled, although bolts and other structures can fill the holes, there will still be gaps between the holes and the bolts. Therefore, in order to improve the protection strength, a layer of paint will also be applied in the holes when applying the coating. During actual installation, this layer of paint can form a close contact with the bolt structure to form an effective partition, making the coating protection of the bracket structure more complete, and the internal structure of the bracket is not easy to corrode, further improving the service life of the bracket system.

[0008] However, during the processing of the bracket, especially the drilling processing of the bracket structure, burrs are inevitably formed at the vertical connection between the hole wall and the outer surface of the bracket. It is not easy to remove such burrs when grinding the outer surface of the bracket. Moreover, during the grinding process of some brackets with higher roughness requirements, when the grinding structure moves along the outer wall of the bracket and passes through the hole structure, it is also easy to form tiny burrs at the vertical connection between the hole and the outer wall of the bracket.

[0009] Although the above-mentioned burrs do not affect the assembly and use of the bracket itself, when the coating is applied later, especially when the hole wall is sprayed, the strength of the paint at the right angle between the two vertical surfaces is not high. In addition, the appearance of uneven structures such as burrs can easily lead to worse bonding strength of this part of the coating, which is easy to fall off during assembly or transportation, resulting in a low degree of bonding with the bolt structure in the later stage, and the hole may still be conductive, affecting the service life of the bracket. Summary of the invention

[0040] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0041] Refer to the instruction manual Figures 1 to 17 A device for processing an offshore photovoltaic module support structure includes a machine base 1, on which a bearing platform 11 and a grinder 2 are arranged, the bearing platform 11 is used to support and fix a bracket 5, a grinding structure 3 is arranged at the output end of the grinder 2, and the grinder 2 is installed on the machine base 1 through a three-axis drive 4.

[0042] A first flexible polishing piece 31 is provided at the bottom of the polishing structure 3, a pressurized chamber 33 is provided inside the polishing structure 3, a flexible layer 32 is provided below the first flexible polishing piece 31, the flexible layer 32 is fixedly installed at the bottom of the first flexible polishing piece 31, the first flexible polishing piece 31 is fixedly installed at the bottom of the flexible layer 32, a pressurized channel 34 is provided inside the polishing structure 3, the pressurized channel 34 is connected to a pressure control unit, and the pressure control unit is used to input or output pressure medium into or out of the pressurized chamber 33 to increase or decrease the pressure in the pressurized chamber 33, but regardless of whether it is decreased or increased, the pressurized chamber 33 maintains a high pressure state.

[0043] During processing, the grinding structure 3 drives the first flexible grinding piece 31 to move relative to the surface of the bracket 5 for grinding. When the first flexible grinding piece 31 moves to the hole of the bracket 5, the pressure in the pressurized chamber 33 causes the flexible layer 32 and the first flexible grinding piece 31 located at the hole to expand, that is, a structure protruding into the hole is generated. The generation of the protruding structure allows the connection between the hole of the bracket 5 and the surface of the bracket 5 to fully contact the first flexible grinding piece 31. Figure 5 The more the first flexible polishing member 31 protrudes from the hole, the higher the contact force between the first flexible polishing member 31 and the edge of the hole, so that the polishing effect on the edge of the hole is better, and the burrs at the connection between the hole of the bracket 5 and the outer wall of the bracket 5 can be fully eliminated, and the edge of the hole can also form a buffer structure similar to a chamfer, refer to the attached manual Figure 7 , different from the instructions Figure 6 The prior art shown only uses a hard grinding structure to form scratches and tiny burrs on the edge of the hole. The hole of the bracket 5 processed in this embodiment is more neat and has a higher adhesion to the coating, especially the chamfer-like structure. When applying the coating later, refer to the attached manual. Figure 8The applied coating can form a certain transition at the vertical connection between the hole and the surface, making the coating at this position less likely to fall off. During the later assembly, it can form effective contact with structures such as bolts, further improving the service life of offshore photovoltaic modules.

[0044] In the above embodiment, a more accurate control system can also be used to control the pressure in the pressurizing chamber 33. For example, a pressure detection unit (pressure sensor) is provided in the pressurizing chamber 33. The pressure detection unit is used to detect the pressure change in the pressurizing chamber 33. When the first flexible grinding member 31 moves to the hole on the bracket 5, since there is no material support at the hole, the initial pressure in the pressurizing chamber 33 is relatively large. Therefore, downward deformation and bulging will occur first. At this time, the pressure detection unit detects that the pressure in the pressurizing chamber 33 is reduced, and the pressure control unit can increase the pressure in the pressurizing chamber 33. 3, so that the bulging part of the first flexible grinding piece 31 in the hole is more prominent, thereby making the contact between the first flexible grinding piece 31 and the edge of the hole wall tighter and the grinding effect better. When the first flexible grinding piece 31 passes over the hole, the pressure in the pressurizing chamber 33 increases relatively. At this time, the pressure control unit hole plum blossom can sense the amount of pressure medium in the pressurizing chamber 33 to reduce the pressure, thereby maintaining the stable contact between the first flexible grinding piece 31 and the surface of the bracket 5. In addition, the pressure control unit can also adjust the pressure in the pressurizing chamber 33 according to other needs to adapt to the processing.

[0045] It should be noted that the principle of grinding is mainly the relative movement between the grinding structure and the workpiece. Therefore, the grinding machine 2 used in this embodiment can be a device for driving the grinding structure 3 to move, and can drive the grinding structure 3 to reciprocate or rotate. The grinding structure 3 can also be driven directly by the three-axis driver 4 to drive the grinding structure 3 to reciprocate. In this embodiment, the commonly used rotary grinding structure is taken as an example, that is, the grinding machine 2 is a motor structure used to drive the grinding structure 3 to rotate, so the pressurized chamber 33 is preferably set at the rotation center of the grinding structure 3. During actual grinding, when encountering a hole on the bracket 5, the center of the grinding structure 3 is preferably driven to align with the hole, and then the grinding structure 3 is soft. When the flexible layer 32 and the first flexible polishing piece 31 expand and bulge downward, the movement of the bulged part and the edge of the hole wall can be a rotational movement, which can improve the polishing effect. The first flexible polishing piece 31 used in this embodiment needs to be a flat structure with a certain flexibility. Therefore, the first flexible polishing piece 31 used in this embodiment is preferably a sandpaper structure, and the flexible layer 32 is directly fixedly connected to the polishing structure 3. The first flexible polishing piece 31 needs to be replaced frequently. The first flexible polishing piece 31 can be bonded to the flexible layer 32, or Velcro (also known as Velcro or snap fastener) can be set between the two to facilitate the disassembly and replacement of the first flexible polishing piece 31.

[0046] Refer to the instruction manual Fig. 9For some brackets 5 whose surface edges are close to right angles, their edge parts also need to fully contact with the first flexible grinding piece 31. Therefore, the pressurized chamber 33 in the grinding structure 3 can be set larger. During actual grinding, the grinding structure 3 can also change its moving route. Therefore, when the pressure in the pressurized chamber 33 increases, not only the first flexible grinding piece 31 at the hole can bulge, but the first flexible grinding piece 31 at the edge of the bracket 5 can also protrude downward, and then in the continuous rotation process of the grinding structure 3, the contact area between the first flexible grinding piece 31 and the edge of the bracket 5 can be increased, thereby improving the grinding efficiency. Moreover, even if the rotation center of the grinding structure 3 is not aligned with the hole, the grinding structure 3 can be controlled to move along a Z-shaped route, and the edge of the hole wall can be effectively ground.

[0047] Refer to the instruction manual Figure 3 Taking the grinder 2 of this embodiment as an example of a motor-type structure, the pressure control unit includes a pump, a docking joint 21 is provided at the output end of the grinder 2, and the grinding structure 3 is installed at the bottom of the docking joint 21. In order to facilitate the replacement of the grinding structure 3, the grinding structure 3 and the docking joint 21 can be detachably connected by using structures such as threads and snaps. The external rotating sleeve of the docking joint 21 is provided with a collar 22 (formed by two semicircular structures fixedly connected), and the collar 22 is fixedly connected to the grinder 2, that is, the docking joint 21 can rotate relative to the collar 22 when working, and an annular cavity is provided inside the collar 22. A docking channel is provided inside the docking joint 21, and the docking channel is connected with the pressurizing channel 34 and the annular cavity. A connecting pipe 23 connected with the annular cavity is installed on the collar 22, and the connecting pipe 23 is connected to the pump through a pressure pipeline, and a control valve is provided on the pressure pipeline for closing the pressure pipeline after adjusting the pressure in the pressurizing chamber 33 to stabilize the pressure in the pressurizing chamber 33.

[0048] It should be noted that the pump used in this embodiment depends on the selected pressure medium, and the pressure medium can be air, water or hydraulic oil, etc. Therefore, the pump can also be an air pump, a water pump and an oil pump, etc., and a corresponding sealing structure is also provided between the collar 22 and the docking joint 21 to ensure the sealing effect of the pressurized chamber 33. Among them, since the medium is added to the grinding structure 3 and the medium flows and changes during the adjustment process, the grinding structure 3 can also have a certain cooling effect, ensuring that the first flexible grinding part 31 will not overheat during the processing process, resulting in the detachment of the first flexible grinding part 31 or affecting the quality of the flexible layer 32.

[0049] For further information, please refer to the attached manual. Figure 1 and Figure 2The three-axis driver 4 includes an X-axis driver 41, a Y-axis driver 42 and a Z-axis driver 43, all of which adopt a commonly used linear drive structure, such as a linear motor structure, wherein the X-axis driver 41 is fixedly mounted on the base 1, the Y-axis driver 42 is mounted on the output end of the X-axis driver 41, the Z-axis driver 43 is mounted on the output end of the X-axis driver 41, and the grinding structure 3 is mounted on the output end of the Z-axis driver 43. The X-axis driver 41, the Y-axis driver 42 and the Z-axis driver 43 are respectively used to drive the grinding structure 3 to move along the X, Y and Z axes to achieve forward driving of the grinding structure 3. In this embodiment, a structure for fixing the bracket 5, such as a pin structure, is provided on the carrier table 11. Pins are set at corresponding positions of the bracket 5 to limit the bracket 5, so that the bracket 5 can be fixed. The bracket 5 usually has multiple surfaces. Therefore, during processing, other surfaces can be processed by adjusting the placement direction of the bracket 5.

[0050] In addition, a rotation driver, such as a driving motor, may be provided between the output end of the Z-axis driver 43 and the grinder 2 to adjust the angle of the grinding structure 3 and improve the grinding effect.

[0051] Since the bracket 5 is ultimately docked with many structures, and some holes have small diameters, when only the pressure medium is used to apply pressure to the first flexible polishing member 31, the first flexible polishing member 31 at the hole is pressed downward and tends to be spherical. Therefore, for holes with smaller diameters, the protruding effect of the first flexible polishing member 31 is not good, and the actual contact effect with the edge of the hole is poor. For this reason, refer to the attached manual. Fig.10 The grinding structure 3 is also provided with a counterweight pressure head 35, which is located in the pressurizing chamber 33. The grinding structure 3 is provided with a counterweight chute 36. The top of the counterweight pressure head 35 is fixedly connected with a counterweight structure 351, and the counterweight structure 351 is slidably arranged in the counterweight chute 36. The counterweight pressure head 35 is preferably a spherical structure. When only one group of counterweight pressure heads 35 is provided in the grinding structure 3, the group of counterweight pressure heads 35 is preferably arranged at the rotation center of the grinding structure 3. When the grinding structure 3 moves to the hole When the hole is in the center, the counterweight pressure head 35 is located at the center of the hole. At this time, the grinder 2 and the grinding structure 3 can be controlled to stay at this position for a period of time for processing. In addition to bulging downward under the pressure of the pressure medium, the first flexible grinding piece 31 at this position is also pressed downward by the gravity of the counterweight pressure head 35 and the counterweight structure 351. At this time, the convex part tends to be a conical structure, which can enhance the contact effect between the first flexible grinding piece 31 and the edge of the hole and improve the processing effect of small-diameter holes.

[0052] For further information, please refer to the attached manual. Fig.11The counterweight pressure head 35 in the grinding structure 3 can also be set to multiple groups, and the multiple groups of counterweight pressure heads 35 are evenly distributed in the pressurizing chamber 33. Correspondingly, the counterweight structure 351 and the counterweight slide 36 are also set to multiple groups. A liquid pressure groove 361 is arranged above the multiple groups of counterweight slides 36. The liquid pressure groove 361 stores a liquid medium. The liquid medium is preferably a liquid with a relatively high density, and can also be a metal liquid, such as mercury. A sealing piston plate 362 is arranged above the liquid medium. The sealing piston plate 362 is slidably installed in the liquid pressure groove 361, and the upper part of the sealing piston plate 362 is connected to the pressurizing channel 34 (to ensure that the counterweight structure 351 is not affected by the pressure in the pressurizing chamber 33 and moves upward, and the counterweight structure 351 is a piston structure, which is relatively sealed with the counterweight slide 36).

[0053] It should be noted that the arrangement of multiple counterweight heads 35 in the grinding structure 3 may not affect the forward path. When the grinding structure 3 advances in a Z-shaped route, there will always be a counterweight head 35 falling in the middle of the corresponding hole, thereby increasing the downward convex effect of the first flexible grinding member 31, especially when a certain counterweight head 35 and the counterweight structure 351 begin to descend, the height of the counterweight structure 351 in the counterweight chute 36 decreases, and the depth of the liquid medium here gradually increases. The amount of liquid above the counterweight structure 351 is greater, and the counterweight structure 351 can be affected by the liquid pressure to increase the downward pressure of the counterweight head 35 below it, thereby further increasing the downward pressure effect of the counterweight head 35.

[0054] In the above-mentioned embodiments, refer to the attached specification. Fig.16, part of the rod structure of the bracket 5 will form two groups of structures in an angled state, and the connection of the structure is welded. Since the two groups of rods are in an acute angle state, it is not easy to fully grind them with an ordinary plane grinding structure, and usually other grinding structures are needed to grind them separately. In this embodiment, a part of the structure can be added to the outside of the grinding structure 3 to simultaneously realize the function of grinding the weld area when welding here. Specifically, the grinding structure 3 is a disc structure, and a plurality of groups of elastic sheets 6 are installed on the circumferential side wall of the grinding structure 3. The elastic sheet 6 is a flexible structure. A second flexible grinding member 61 is provided on the side of the elastic sheet 6 corresponding to the rotation direction of the grinding structure 3, so that the grinding structure 3 During the rotation process, the elastic sheet 6 and the second flexible polishing piece 61 can also be driven to move, especially when the polishing structure 3 gradually approaches the angle area of ​​the bracket 5, the elastic sheet 6 and the second flexible polishing piece 61 are in an extended state, and the elastic sheet 6 and the second flexible polishing piece 61 can automatically deform under the restriction of the angle area, and gradually contact and pass through the welding parts of the angle area for effective polishing, and the polishing structure 3 itself does not need to contact the welding parts of the angle area. Therefore, the device can fully polish part of the angle area while polishing the surface of the bracket 5, and the elastic sheet 6 is used to support the second flexible polishing piece 61 to avoid the second flexible polishing piece 61 from breaking.

[0055] It should be noted that the material selection of the second flexible polishing piece 61 and the connection between the elastic sheet 6 and the second flexible polishing piece 61 can refer to the above-mentioned first flexible polishing piece 31, and the drawings in the specification of the present invention only use the elastic sheet 6 with a straight structure in a natural state as an example. When making a specific selection, the elastic sheet 6 can also use an arc structure or other structures.

[0056] Furthermore, since the second flexible polishing member 61 is also a consumable, in order to facilitate the replacement of the second flexible polishing member 61, the elastic sheet 6 is preferably detachably connected to the polishing structure 3, for example, referring to the attached manual. Fig.13 and Fig.14 One end of the elastic sheet 6 is fixedly connected with a snap-fit ​​structure 63, and a snap-fit ​​groove 37 is provided at the edge of the grinding structure 3. The snap-fit ​​structure 63 is snap-fitted and installed in the snap-fit ​​groove 37, thereby facilitating the installation of the elastic sheet 6 and the second flexible grinding member 61. In order to make the installation of the second flexible grinding member 61 more stable, one end of the second flexible grinding member 61 is also clamped in the snap-fit ​​groove 37 during installation.

[0057] Furthermore, a reinforcing structure 62 (e.g., a convex rib structure) is provided on the top side of the elastic sheet 6 away from the second flexible grinding member 61. The reinforcing structure 62 is used to increase the strength of the top structure of the elastic sheet 6 and reduce the elastic deformation capacity of the top structure of the elastic sheet 6 (not to prevent deformation, but to make the bottom of the elastic sheet 6 more easily deformed than the top). Therefore, when the elastic sheet 6 rotates with the grinding structure 3, it is affected by the airflow and the centrifugal force. Fig.15 The bottom of the elastic sheet 6 is easier to deform, which will produce relative hysteresis, so that the elastic sheet 6 and the second flexible polishing member 61 can form a fan blade structure. When the polishing structure 3 drives the elastic sheet 6 to rotate, an airflow can also be formed, which can scrape and throw out the debris generated by polishing on the surface of the bracket 5, and take away the nearby debris. In particular, when the elastic sheet 6 passes through the processed hole, due to the connection formed at the hole, the downward airflow formed by the second flexible polishing member 61 can blow away the debris on the hole wall of the bracket 5, thereby improving the cleanliness of the hole wall and ensuring the bonding effect of the coating when the coating is applied later.

[0058] Refer to the instruction manual Fig.17 In order to make the lower part of the elastic sheet 6 easier to deform, the elastic sheet 6 can be set to a structure that is wide at the top and narrow at the bottom, and the elastic sheet 6 itself can be made of a rubber structure or a plastic structure. Moreover, since the elastic sheet 6 is engaged with the polishing structure 3 and installed, it is easy to replace and convenient to use.

[0059] Since the bracket 5 needs to be coated later, the surface of the bracket 5 needs to be kept smooth after polishing. In the above scheme, the debris on the surface of the bracket 5 is swept and blown away by the elastic sheet 6, but some dust will accumulate on the carrier 11 and affect the subsequent use. For this reason, refer to the attached manual. Figure 2 A dust collecting window 12 is provided on one side of the carrier 11, and a plurality of dust suction holes are provided on the surface of the carrier 11. A dust collector 13 is installed inside the base 1, and the dust collector 13 is provided with an exhaust air passage corresponding to the dust collecting window 12 and the holes on the carrier 11, so that during the processing, the dust can be timely sucked away and collected by the exhaust of the dust collector 13. In addition, since the holes on the bracket 5 usually penetrate the side walls of the bracket 5, that is, there are two holes penetrating at the corresponding positions, refer to the attached manual Fig.16 A dust extraction pipe 111 is provided at the hole corresponding to the bracket 5 in the supporting platform 11, and the dust extraction pipe 111 is connected to the exhaust end of the dust collector 13, so that a downward airflow can be formed at the upper and lower through holes of the bracket 5. The downward airflow formed when the elastic sheet 6 passes through can improve the cleaning effect of the debris on the hole wall of the bracket 5, avoid the problem that the processed debris enters the interior of the bracket 5 and is difficult to clean, and further improve the practicality of the equipment.

[0060] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
