[0045] In the embodiment, the quick installation structure 2 includes:

[0046] U-shaped piece 21, the U-shaped piece 21 is nested on the outer side of purlin, has bottom edge 211 and side edge 212, the opening part of the U-shaped piece is arranged above the purlin, and the opening part is provided with clamping groove 213, the extension direction of the clamping groove 213 corresponds to the extension direction of C surface, the clamping groove 213 is clamped with C surface 102, and the two side edges 212 of U-shaped piece correspond to the two side surfaces of purlin 13 and are attached, to limit the relative longitudinal movement between them, and the bottom edge of U-shaped piece is provided with through hole;

[0047] Upper limiting assembly, the upper limiting assembly is connected with the opening part of U-shaped piece and is limited to cooperate with B surface, to limit the relative sliding of C surface and clamping groove and the sliding of photovoltaic module along purlin installation plane, i.e.

[0048] Lower limiting assembly, the lower limiting assembly includes connecting shaft 24 and support connected with the upper end of connecting shaft, the connecting shaft passes through the through hole, and the connecting shaft 24 and U-shaped piece are provided with limiting mechanism, the relative position of connecting shaft and U-shaped piece is limited by limiting mechanism, so that the support is in contact with the bottom surface of purlin, to limit the movement of photovoltaic module in the direction perpendicular to purlin installation plane.

[0049] Wherein U-shaped piece is nested on the outer side of purlin, to connect the quick installation structure with purlin, the opening part of U-shaped piece is arranged above the purlin, and is provided with clamping groove, the extension direction of the clamping groove corresponds to the extension direction of C surface, so that the clamping groove and C surface are clamped, to connect the quick installation structure with frame.

[0050] Because the clamping groove is clamped with C edge, at the same time, the relative position of connecting shaft and U-shaped piece is limited by limiting mechanism of lower limiting assembly, so that the support is in contact with the bottom surface of purlin, to limit the movement of photovoltaic module in the direction perpendicular to purlin installation plane, so as to fix photovoltaic module on purlin, without bolt, improve installation efficiency.

[0051] In addition, since the upper limiting assembly is connected with the U-shaped piece and is limited with the B face, the C face and the clamping groove are prevented from being separated due to relative sliding, and the fixing effect of the lower limiting assembly is combined, so that the photovoltaic module is limited to slide along the purlin installation plane. Therefore, the freedom of the photovoltaic module in each direction is limited, and the fastening effect can be improved.

[0052] The bottom edge of the U-shaped piece is provided with a through hole, and the connecting shaft is movably arranged through the through hole. In this way, the connecting shaft can be kept in a straight state, so that the support connected to the upper end abuts against the bottom surface of the purlin, and sufficient force is ensured to limit the movement of the photovoltaic module in the direction perpendicular to the purlin installation plane.

[0053] Specifically, the upper limiting assembly includes limiting side plates 22 corresponding to the two side edges of the U-shaped piece and a limiting bolt 23 connecting the two limiting side plates. The limiting bolt 23 is limited with the purlin installation plane. The limiting side plate can be rotated upward to a position convenient for inserting the limiting bolt, and then the limiting bolt is inserted.

[0054] The limiting side plate 22 is in an L-shaped structure, including a vertical edge 222 and a horizontal edge 221. The horizontal edge is hinged to the side edge of the U-shaped piece through a pin shaft 223. The limiting bolt is connected to the pin hole 224 on the vertical edge. When the limiting bolt is limited with the purlin installation plane, the vertical edge is limited with the B face. In the normal state, the vertical edge is in a drooping position due to gravity. During installation, the limiting side plate is rotated so that the vertical edge is in an upward position, and then the limiting bolt is inserted. When the limiting bolt is limited with the purlin installation plane, the vertical edge is limited with the B face. It can be understood that the gap between the limiting bolt and the purlin installation plane is as small as possible or has no gap. In this way, the limiting side plate cannot be rotated, the vertical edge is tightly fitted with the B face, and the photovoltaic module can be completely limited to slide along the purlin installation plane.

[0055] Further, the clamping groove is provided with a notch 2132 on one side of the opening. When the clamping groove is engaged with the C face, the lower side wall of the clamping groove first abuts against the lower side of the C face, and then the clamping groove is pushed along the installation plane to engage with the C face. Therefore, the notch can facilitate the engagement of the clamping groove with the C face. The clamping groove is provided with an anti-skid surface 2131, such as a sawtooth surface on the upper side wall of the clamping groove. When the photovoltaic module is fixed on the purlin, the clamping groove is engaged with the C face, and the sawtooth surface is fitted with the C face to prevent the C face and the clamping groove from sliding relative to each other.

[0056] Specifically, the limiting mechanism comprises at least one limiting slot 214 arranged on the two side edges of the U-shaped member and vertically distributed, and a pressure bearing rod 25 vertically intersecting with the connecting shaft, two ends of the pressure bearing rod 25 being connected with the limiting slots on the two side edges of the U-shaped member, so that the relative position of the connecting shaft and the U-shaped member is fixed, and the support member and the bottom surface of the purlin can be kept in sufficient action, so as to ensure sufficient force to limit the photovoltaic module from moving in a direction perpendicular to the installation plane of the purlin.

[0057] Further, the two side edges of the U-shaped member are provided with downwardly open elongated slots 215, the elongated slots vertically extending and the limiting slots being arranged on one of the vertical side walls of the elongated slots, and the limiting slots being arranged in at least two along the up-down direction of the side edge of the U-shaped member. In the embodiment, the bottom edge of the U-shaped member is provided with a communication slot extending along the length direction and penetrating the elongated slots on the two side edges of the U-shaped member, so that the through hole can be regarded as a part of the communication slot, which facilitates the installation of the lower limiting assembly. The pressure bearing rod can move in the elongated slot, and for the design of multiple limiting slots arranged along the up-down direction of the side edge of the U-shaped member, the pressure bearing rod can be selectively moved in the elongated slot and cooperated with one of the limiting slots, so as to ensure the abutment of the support member and the bottom surface of the purlin, and the U-shaped member can be cooperated with purlins of different heights.

[0058] Anti-slip patterns can be arranged on the slot wall of the limiting slot. In order to prevent the pressure bearing rod from being separated from the limiting slot, an anti-slip piece 216 can also be arranged on the two side edges of the U-shaped member, the anti-slip piece 216 being in inverted U-shaped structure, a first side edge serving to close the opening of the limiting slot and preventing the pressure bearing rod from being separated from the limiting slot, and the other side edge being fixed on the side edge of the U-shaped member. A limiting rod 217 is also arranged on the two side edges of the U-shaped member, the limiting rod 217 serving to fix the other side edge of the anti-slip piece 216, so that the pressure bearing rod is actually fixed in the limiting slot by cooperating with the anti-slip piece to prevent the pressure bearing rod from being separated from the limiting slot.

[0059] Specifically, the support member comprises a support spring 26 and a limiting block 27, the lower end of the support spring being connected with the upper end of the connecting shaft, the upper end being elastically abutted with the limiting block, and the limiting block 27 being elastically abutted with the bottom surface of the purlin. In this way, the limiting block has a certain up-down movement space, so as to ensure the elastic abutment with the bottom surface of the purlin at all times. A plurality of grooves 131 can also be arranged on the bottom surface of the purlin along the length direction, the grooves 131 being limitingly cooperated with the limiting block 27, so as to have better limiting effect. The limiting block and the grooves are adaptively shaped, for example, both being rectangular. The bottom of the limiting block can be connected with an extension rod, the extension rod being movably cooperated with the upper end of the connecting shaft, and the support spring 26 being sleeved on the extension rod, so that the support spring can keep straight state and keep the upper end elastically abutted with the limiting block. The lower end of the connecting shaft is connected with a bottom plate 28. The bottom plate is located below the bottom edge of the U-shaped member and serves to upwardly push the pressure bearing rod and fix the two ends of the pressure bearing rod in the limiting slots.

[0060] Preferably, the U-shaped piece 21 is an aluminum alloy or stainless steel profile or sheet metal piece. The limiting side plate 22 is a sheet metal piece, and the limiting bolt 23 is a steel bar. Of course, the pressure-bearing rod 25 can also be a profile, and the supporting spring is a common compression spring. The purlin 13 is a C-shaped structure. In this way, the main components of the quick installation structure use mature components, which can be mass-produced industrially, thereby reducing costs and having the advantages of high reliability, convenient and safe installation and use, and high safety, which can greatly reduce the construction and labor costs of photovoltaic module installation and fixation, and solve the problem of high component installation cost of photovoltaic power station construction.

[0061] Before installation, the limiting bolt is not inserted, and the pressure-bearing rod is not fixed in the limiting groove. The U-shaped piece can be nested outside the purlin, at which time the U-shaped piece and the purlin can be relatively movable. Then, the limiting side plate is rotated to place the vertical edge in the upper vertical position. Then, the limiting bolt is inserted. Finally, the bottom plate is pushed upward to connect the shaft, so that the pressure-bearing rod is aligned with the limiting groove, and the pressure-bearing rod is fixed at both ends in the limiting groove, thereby fixing the pressure-bearing rod and limiting the limiting block and the groove. The limiting bolt and the purlin installation plane are limited to cooperate with the vertical edge and the B surface, so as to fix the photovoltaic module on the purlin and prevent the photovoltaic module from falling off.

[0062] It can be understood that the quick installation structure of the utility model can adapt to various installation scenes, including roof installation or other installation scenes with purlins.
