[0023] The large photovoltaic module is composed of a plurality of photovoltaic panels in a rectangular array paving manner and installed on the installation support. Regarding the installation process of the photovoltaic panel and the installation support: first, the photovoltaic panel is placed in the designated installation area of the installation support, and the installation support is used to support the photovoltaic panel; then the photovoltaic panel and the installation support are fixed to each other by using bolts. Since the area of a single photovoltaic panel is large, when the bolts are fixed to the far corner of the photovoltaic panel, the worker needs to lie on the panel surface of the photovoltaic panel due to the limitation of the length of the worker's arm, so as to perform the bolt fixing operation. In this way, the photovoltaic panel is directly pressed by the worker, which is easy to cause hidden cracks on the panel surface of the photovoltaic panel, resulting in quality defects and causing safety accidents.

[0024] In order to solve the above technical problems, the present application provides a photovoltaic module installation auxiliary device.

[0025] Please refer to Figures 1-2 In an embodiment of the present application, the photovoltaic module installation auxiliary device comprises a flat plate layer 10 and a soft cushion layer 20 arranged in a top-down manner, and the flat plate layer 10 is located above the soft cushion layer 20. The side of the flat plate layer 10 away from the soft cushion layer 20 is used for the worker to lie on, and the side of the soft cushion layer 20 away from the flat plate layer 10 is used to contact the panel surface of the photovoltaic panel. In this embodiment, the soft cushion layer 20 can be made of sponge material.

[0026] The technical solution of the present application sets the flat plate layer 10 and the soft cushion layer 20 in a top-down stacked structure, wherein the side of the flat plate layer 10 away from the soft cushion layer 20 is used for the worker to lie on, and the side of the soft cushion layer 20 away from the flat plate layer 10 is used to contact the panel surface of the photovoltaic panel. Compared with the background technology, the worker directly lies on the surface of the photovoltaic panel, and the body weight is concentrated on the protruding parts such as ribs and knees, and the local pressure far exceeds the allowable value of glass, which causes hidden cracks on the panel surface of the photovoltaic panel. The present application can convert the original point contact into surface contact, and further disperse the load by using the elastic deformation of the soft cushion layer 20, so that the maximum pressure on the panel surface of the photovoltaic panel is greatly reduced; thereby realizing the installation operation of the photovoltaic panel and the installation support, and at the same time, the hidden cracks on the panel surface of the photovoltaic panel are not caused.

[0027] As a preferred scheme of the above-mentioned embodiment, referring to Figure 3 , the photovoltaic module installation auxiliary device further comprises a buffer layer 30 arranged between the flat plate layer 10 and the soft cushion layer 20; the buffer layer 30 comprises an annularly-structured elastic belt 31 and an inflatable elastic deformation pipe 32 arranged inside the annular elastic belt 31; the upper edge of the elastic belt 31 is connected to the flat plate layer 10, and the lower edge of the elastic belt 31 is connected to the soft cushion layer 20; the elastic deformation pipe 32 is installed on the flat plate layer 10, and the pipeline of the elastic deformation pipe 32 is arranged in a serpentine shape. In this way, an additional buffer layer 30 is arranged between the flat plate layer 10 and the soft cushion layer 20, which is equivalent to arranging a buffer air bag, achieving multi-point support to avoid local stress concentration and further reducing the pressure on the underlying photovoltaic panel. The buffer layer 30 is composed of two parts: an annular elastic belt 31 and an inflatable elastic deformation pipe 32. The upper edge of the elastic belt 31 is sewn or clamped to the bottom surface of the flat plate layer 10, and the lower edge is also fixed to the top surface of the soft cushion layer 20, forming an axially expandable skirt. The elastic deformation pipe 32 is arranged in the annular space formed by the elastic belt 31 and is directly anchored to the lower surface of the flat plate layer 10; the pipeline of the elastic deformation pipe 32 is arranged in a serpentine shape, which is equivalent to being folded back and forth in the same plane, with multiple segments connected in parallel. The purpose of this design is that when the elastic deformation pipe 32 is inflated with a pump, the serpentine pipe segments expand synchronously, the overall thickness increases rapidly, driving the elastic belt 31 to stretch upwards, thereby lifting the flat plate layer 10 as a whole; after deflation, the serpentine pipe contracts, and the elastic belt 31 folds, returning the entire device to a thin state for easy storage. The serpentine arrangement maximizes the pipe length within a limited area, allowing for greater expansion and more stable lifting. The inflation port 33 of the elastic deformation pipe 32 can be arranged on the surface of the flat plate layer 10 and sealed with a screw-on cover. In this embodiment, the elastic deformation pipe 32 can be made of rubber material.

[0028] As a preferred scheme of the above-mentioned embodiment, referring to Figures 1-2The photovoltaic module installation auxiliary device further comprises a support structure 40 for supporting the flat plate layer 10 to reduce the partial weight borne by the soft cushion layer 20. Specifically, the support structure 40 comprises two support frames 50 symmetrically arranged on opposite sides of the flat plate layer 10. Each support frame 50 comprises a connecting beam 51, the bottom of which is provided with at least two support foot assemblies 52 symmetrically arranged on opposite sides of the bottom of the connecting beam 51. The support foot assemblies 52 are used to support on the ground. The side of the connecting beam 51 is provided with at least two connecting rods 53 arranged on opposite sides of the side of the connecting beam. The connecting rods 53 are used to be connected with the flat plate layer 10. In this way, the support structure 40 is equivalent to adding a pair of support legs to the flat plate layer 10 which is originally completely pressed on the panel surface of the photovoltaic panel, and directly transferring the weight of the worker to the ground through the support legs. It is provided with a connecting beam 51 on the left and right sides of the flat plate layer 10, and the bottom of each connecting beam 51 is symmetrically provided with a plurality of support foot assemblies 52. The support foot assemblies 52 are used to extend to the ground through the gap between the two photovoltaic panels, so that the support foot assemblies 52 fall on the ground to form a stable grounding fulcrum. The side of the connecting beam 51 is symmetrically provided with a connecting rod 53, and the connecting rod 53 is connected with the flat plate layer 10, so that the flat plate layer 10 is suspended between the connecting beams 51. Therefore, when the worker is prone, the load is mainly transmitted to the ground through the connecting beams 51 and the support foot assemblies 52, and the soft cushion layer 20 only needs to keep close and buffer, and the weight borne by it is greatly reduced, thereby significantly reducing the extrusion on the photovoltaic panel. The symmetrically arranged support frames 50 ensure balanced force, avoid overturning caused by one-sided overload, and realize the safe operation mode of close without pressure. In this embodiment, each support frame 50 is provided with four support foot assemblies 52 and two connecting rods 53.

[0029] Further, with reference to Figure 4The inner part of the flat plate layer 10 is provided with a cavity area 11, and the cavity area 11 is fixedly provided with a connecting frame 12; one end of the connecting rod 53 extending away from the connecting beam 51 extends to the cavity area 11, and the connecting rod 53 is slidingly connected to the inner side of the frame-shaped connecting frame 12; so that the support frame 50 can move close to or away from the flat plate layer 10; and one end of the connecting rod 53 extending away from the connecting beam 51 is fixedly provided with a limiting piece 531, and the limiting piece 531 abuts against the connecting frame 12. In this way, the cavity area 11 is arranged in the inner part of the flat plate layer 10, and the rigid connecting frame 12 is fixed in the cavity area 11. The connecting rod 53 is directly inserted into the frame-shaped sliding channel of the connecting frame 12 to form a sliding fit: the connecting rod 53 can slide left and right along the frame wall, driving the entire support frame 50 to close to the center of the flat plate layer 10 or to expand outward. In this way, the span of the two side support frames 50 can be adjusted at any time according to the width of the on-site components without the need to replace parts. The tail end of the connecting rod 53 is also provided with a limiting piece 531, which abuts against the end face of the connecting frame 12 when the support frame 50 slides to the maximum outward expansion position, preventing the connecting rod 53 from continuing to move outward and derailing, ensuring that the adjustment process is always free to stretch and cannot be separated, which not only considers universality, but also maintains the safety of the overall connection.

[0030] Further, with reference to Figures 4-5 The middle part of the side of the connecting beam 51 is provided with a sliding rod 54, and the sliding rod 54 is arranged in parallel with the connecting rod 53; the opposite side of the corresponding sliding rod 54 of the two support frames 50 is provided with a rack structure 541; the cavity area 11 of the flat plate layer 10 is rotatably connected with a gear piece 13, the gear piece 13 is arranged between the two sliding rods 54, and the gear piece 13 is synchronously meshed with the rack structure 541 of the two sliding rods 54. In this way, a sliding rod 54 parallel to the connecting rod 53 is arranged in the middle part of each of the two side connecting beams 51, and the opposite side walls of the two sliding rods 54 are respectively machined with rack structures 541. At the same time, the cavity area 11 of the flat plate layer 10 is provided with a freely rotatable gear piece 13, which can be simultaneously meshed with the upper and lower two rack structures 541, forming a "gear-double rack" linkage mechanism. When the operating personnel push or pull any support frame 50, the rack structure 541 of the sliding rod 54 belonging to any support frame 50 synchronously transmits the movement to the other support frame 50 through the gear piece 13, so that the two side support frames 50 are always simultaneously closed or expanded at equal distances, ensuring that the flat plate layer 10 is always centered and symmetrically stressed, avoiding unilateral sliding caused by partial load or jamming; and the adjustment process can be completed with one hand without the need for additional tools, which not only improves the operation efficiency, but also ensures the stability of the structure.

[0031] As a preferred scheme of the above embodiment, with reference to Figure 5The limiting structure 60 is arranged on the upper area of the gear member 13. The flat plate layer 10 is provided with a through-going threaded hole 14. The middle part of the limiting bolt 61 is threadedly connected with the threaded hole 14. The end part of the limiting bolt 61 is provided with a limiting plate 62. The limiting plate 62 is in abutment with the threaded hole 14. The side of the limiting plate 62 facing the gear member 13 is used to press the gear member 13, so as to limit the rotating movement of the gear member 13. In this way, the threaded hole 14 is arranged on the upper area of the gear member 13. A limiting bolt 61 is screwed into the threaded hole 14. The lower end of the limiting bolt 61 is fixed with a limiting plate 62. When the support frame 50 is adjusted to the required span, the limiting bolt 61 is only needed to be screwed downward. The limiting plate 62 is lowered and tightly abuts against the tooth top of the gear member 13. The gear member 13 cannot continue to rotate by means of the friction force. Since the gear member 13 is locked, the two sliding rods 54 are also fixed. The relative sliding between the support frame 50 and the flat plate layer 10 is completely limited. The whole frame is instantly changed from the adjustable state to the rigid state. When it is needed to adjust again, the limiting bolt 61 is loosened in the reverse direction. The limiting plate 62 is separated from the gear member 13. The gear member 13 can be freely rotated. The support frame 50 also restores the sliding ability. The structure only needs one bolt action to complete the locking or releasing. The operation is quick. The locking force is directly applied to the center of the gear member 13. The stress is balanced. The support frame 50 is prevented from being displaced by itself due to vibration or pushing and pulling during the operation.

[0032] Further, the end part of the threaded hole 14 is provided with a countersunk head 15. The countersunk head 15 is used to accommodate the bolt head of the limiting bolt 61. In this way, a larger diameter countersunk head 15 is machined on the opening of the threaded hole 14 on the upper surface of the flat plate layer 10. When the limiting bolt 61 is screwed into place, the bolt head is completely sunk into the countersunk head 15 and does not protrude from the upper surface of the flat plate layer 10. In this way, the worker does not get pricked by the bolt head when he lies down. The tool or clothes are also prevented from being hooked. The risk of loosening of the bolt head due to external force impact is reduced. The locking state is more stable and safe.

[0033] Further, the side of the limiting plate 62 facing the gear member 13 is provided with an elastic layer 63 with anti-skid lines. In this way, the side of the limiting plate 62 facing the gear member 13 is covered with an elastic layer 63 with anti-skid lines. When the limiting bolt 61 is tightened downwards, the elastic layer 63 first contacts the tooth top of the gear member 13 and is slightly compressed, which on the one hand increases the contact area and on the other hand embeds the anti-skid lines into the tooth gap, forming a "soft bite" effect. The friction force generated thereby is much greater than the friction coefficient of metal directly pressing metal, so that even if subjected to vibration or lateral thrust, the gear member 13 is firmly locked and is not easy to appear micro-rotation or looseness; at the same time, the elastic layer 63 can also absorb impact to avoid damage to the tooth surface caused by rigid impact and prolong the service life.

[0034] As a preferred solution of the above-mentioned embodiments, reference is made to Figure 6The support leg assembly 52 comprises a cylindrical member 70 coaxially arranged and a columnar member 80. One end of the cylindrical member 70 is fixedly connected with the connecting beam 51, and the other end of the cylindrical member 70 is slidably connected with the columnar member 80. The side wall of the cylindrical member 70 is provided with a first sliding groove 71 and a plurality of second sliding grooves 72. The groove direction of the first sliding groove 71 is parallel to the axial direction of the cylindrical member 70. The plurality of second sliding grooves 72 are distributed along the groove direction of the first sliding groove 71, and the groove direction of the second sliding grooves 72 is arranged along the circumferential direction of the cylindrical member 70. One end of the columnar member 80 is provided with a sliding member 81, which is slidably connected in the first sliding groove 71 and the second sliding grooves 72. The other end of the columnar member 80 extends to the outside of the cylindrical member 70 and is fixedly provided with a first connecting member 82. The other end of the cylindrical member 70 is provided with a second connecting member 74. The outside of the columnar member 80 is sleeved with a spring member 90, and the two ends of the spring member 90 are respectively connected with the first connecting member 82 and the second connecting member 74. In this way, the support leg assembly 52 is designed as a quick telescopic connecting structure: an outer sleeve of a cylindrical member 70 and an inner insertion of a columnar member 80 coaxially slide. At the same time, the first sliding groove 71 is arranged on the side wall of the cylindrical member 70, and the sliding member 81 is slidably connected with the first sliding groove 71 to guide the sliding movement of the columnar member 80 along the axial direction of the cylindrical member 70. A plurality of second sliding grooves 72 are branched out along the transverse direction of the first sliding groove 71, forming a multi-stage bayonet. After the sliding member 81 at the top end of the columnar member 80 slides up and down along the first sliding groove 71 to the appropriate height, only a slight rotation of the columnar member 80 is needed, and the sliding member 81 can be clamped into the second sliding groove 72 of the corresponding height to realize gear locking. At the same time, the columnar member 80 is sleeved with a spring member 90, and the two ends of the spring member 90 are respectively connected with the first connecting member 82 (moving with the columnar member 80) and the second connecting member 74 (fixed at the lower end of the cylindrical member). The spring member 90 is used to apply an elastic force to the columnar member 80 in the direction of the cylindrical member 70 (i.e. upward direction). In this way, the spring member 90 provides an elastic force, so that when the sliding member 81 is disengaged from the second sliding groove 72, it can slide along the first sliding groove 71 under the elastic force, making it easier to switch gears, eliminating the idle stroke, and ensuring that the support leg can quickly set and maintain a stable length under different ground heights.

[0035] Further, the third chute 73 is provided at one end of the second chute 72 away from the first chute 71, and the groove direction of the third chute 73 is parallel to the axial direction of the cylinder member 70, and the groove direction of the third chute 73 extends away from the end of the second connecting member 74. In this way, at the end of each transverse second chute 72, a short and straight third chute 73 is continued to extend downward, and the direction of the third chute 73 is again parallel to the axial direction of the cylinder member 70. When the sliding member 81 of the columnar member 80 is turned into the end of the second chute 72, the sliding member 81 will slide into the end of the third chute 73 under the elastic force of the spring member 90, and the sliding member 81 will be further limited by the spring member 90 at the end of the third chute 73, forming a self-locking; unless the operator manually moves and reversely rotates the columnar member 80, the sliding member 81 cannot automatically return to the second chute 72. In this way, the supporting leg will not be accidentally off the track due to impact or accidental touch during the operation, and the height locking is more reliable.

[0036] As a preferred solution of the above embodiment, referring to Figure 1 The front end of the flat plate layer 10 is provided with a drawer structure 16, and the drawer structure 16 is used to accommodate the required tools for the installation operation of the photovoltaic panel and the mounting bracket. In this way, a pullable drawer structure 16 is reserved at the front end of the flat plate layer 10. During operation, the mounting tools such as fixing bolts and electric wrenches can be taken out and put in as needed by pulling out the drawer structure 16 like a desk drawer; after finishing, the drawer structure 16 is pushed back to the original position, and the drawer opening is flush with the flat plate surface, without occupying extra space. In this way, the operator does not need to repeatedly get up or ask others to deliver tools, and all operations are completed within the range of prone position, which shortens the operation time and avoids the risk of falling of small parts from high altitude.

[0037] It should be noted that other contents of the photovoltaic module installation auxiliary device disclosed in the present application are prior art, and will not be described here.

[0038] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application, and any direct / indirect application of the present application in other related technical fields is included in the patent protection scope of the present application.
