Description

Technical Field

[0001] The present invention relates to the field of transportation technology, in particular to a multi-layer photovoltaic panel placement rack. Background Art

[0002] The production and processing of photovoltaic panels require the use of a variety of different processing equipment and auxiliary equipment, including transfer racks, which are mainly used to provide temporary storage for the completed photovoltaic panels and facilitate position transfer operations; existing transfer racks usually include a transfer base and multi-layer placement boards fixed vertically and equidistantly on the transfer base. When in use, multiple photovoltaics are directly placed on different placement boards for temporary storage and transfer; but during the transfer, the placement boards can only serve to place the photovoltaic panels, and cannot limit their position, resulting in the photovoltaic panels may fall from the placement boards during the transfer, causing damage to the photovoltaic panels.

[0003] To solve the above problems, a Chinese patent with publication number CN219790812U discloses a high-protection photovoltaic panel transfer rack structure, including a bottom support frame, a plurality of placement layers are arranged above the bottom support frame, and the plurality of placement layers are stacked. An installation groove is provided on the upper surface of the placement layer, and a protective airbag is pasted inside the installation groove. A limit bracket is fixedly connected to the symmetrical side surfaces of the placement layer, and a clamping bracket is movably installed on the outside of the limit bracket, and a clamping spring is sleeved on the outside of the limit bracket. Each layer of placement layer in this patent can limit the photovoltaic panel, thereby preventing the photovoltaic panel from falling during transportation, and providing all-round protection for the photovoltaic panel.

[0004] The following problems exist during the actual use of the above patent: 1. When limiting the photovoltaic panel, it is necessary to manually pull the clamping bracket upward to compress the clamping spring, thereby providing space for the photovoltaic panel to be placed in the installation slot; then release the clamping bracket, so that the clamping bracket moves downward under the action of the clamping spring to press the photovoltaic panel, thereby achieving the limitation of the photovoltaic panel; using this method to limit each layer of photovoltaic panels is cumbersome and inefficient; 2. During the limitation of the photovoltaic panel, two staff members are required, one staff member is used to adjust the height of the clamping bracket, and the other staff member is used to place the photovoltaic panel, resulting in increased labor costs; 3. Since the multiple layers of placement panels are arranged at equal distances vertically, when adjusting the vertical height of the clamping bracket for the middle or lower placement panel, it will be restricted by the adjacent placement panels, which increases the difficulty of adjusting the height of the clamping bracket and the difficulty of placing the photovoltaic panel. Summary of the Invention

[0005] The present invention aims to provide a multi-layer photovoltaic panel placement rack to solve the problem of complicated operation of the existing transfer rack's limiting method for multiple photovoltaic panels.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a multi-layer placement rack for photovoltaic panels, comprising a box body and a plurality of placement boards, a plurality of openings being equidistantly provided on the side walls of the box body, a plurality of placement boards being vertically equidistantly fixed in the box body, the placement boards being inclined, a height of one end of the placement board close to the opening being greater than a height of the other end of the placement board away from the opening, and a fixing plate being vertically provided on the placement board; a plurality of limiting mechanisms being vertically equidistantly provided in the box body, the limiting mechanism comprising a rotating shaft rotatably connected to both sides of the placement board, a limiting plate being provided on the rotating shaft for abutting against the side walls of the photovoltaic panel, and the rotation directions of the two rotating shafts being opposite; and a power mechanism being further provided for driving two rotating shafts in a plurality of limiting mechanisms to rotate simultaneously.

[0007] The principles and advantages of this solution are: 1. This solution places the photovoltaic panel through the opening onto the placement plate in the box, so that the photovoltaic panel is in an inclined state, and the right end of the photovoltaic panel is against the fixed plate. Compared with the existing technology, the placement plate in the inclined state can play a preliminary limiting role for the photovoltaic panel, so that the photovoltaic panel can automatically be against the fixed plate, preventing the photovoltaic panel from falling from the opening, thereby avoiding damage to the photovoltaic panel.

[0008] 2. This solution can drive the two rotating shafts in multiple limit mechanisms to rotate simultaneously through the power mechanism. The rotating shaft drives the limit plate to rotate, so that the limit plate and the upper end of the photovoltaic panel are abutted against each other, thereby achieving the tightness of the photovoltaic panel, that is, the positioning of the photovoltaic panel, so that the photovoltaic panel will not shake during transportation, thereby avoiding damage to the photovoltaic panel; compared with the existing technology, the above method can be used to position each photovoltaic panel on the placement board, which is simpler to operate and more efficient.

[0009] Furthermore, the power mechanism includes an adjustment part that is vertically equidistantly arranged in the box body, and the adjustment part includes a position between two adjacent placement plates; the adjustment part includes a slide groove opened on the inner wall on both sides of the box body, and a slider is slidably connected in the slide groove; it also includes a power part for simultaneously driving multiple sliders to move and a linkage part that drives the two rotating shafts in the limiting mechanism to rotate simultaneously with the movement of the slider.

[0010] With the above arrangement, the power unit drives the multiple sliders to move laterally at the same time. During the lateral movement of the sliders, the linkage unit drives the two rotating shafts in the limiting mechanism to rotate simultaneously.

[0011] Furthermore, an inclined surface is provided on the slider, and the bottom of the placement plate is located on the movement track of the inclined surface.

[0012] Through the above setting, when the slider moves to the right, the inclined surface also moves accordingly, so that the inclined surface is against the bottom of the placement plate, thereby supporting the placement plate and further improving the stability of the placement plate in supporting the photovoltaic panel.

[0013] Furthermore, the power part includes a bottom block fixed to the slider, a vertical groove opened on the top of the box body, and several power units arranged vertically equidistantly in the box body, a vertical block is slidably connected in the vertical groove, and a first spring is provided between the vertical block and the vertical groove; the power unit is located between two adjacent placement plates, the power unit includes a wall groove opened on the inner wall of the box body, an inclined groove opened on the inner walls on both sides of the box body, the wall groove is communicated with the vertical groove, a lifting block is vertically slidably connected in the wall groove, a horizontal groove is provided on the lifting block, a horizontal block is slidably connected in the horizontal groove, a top groove is provided on the top of the horizontal block, and the bottom block is slidably connected to the top groove; two inclined grooves are located on both sides of the wall groove, an auxiliary block is slidably connected in the inclined groove, and the auxiliary block is fixed to the horizontal block; and it also includes a stopping unit for stopping the vertical block.

[0014] Through the above arrangement, the vertical block is pressed to move downward and is stopped by the stopping unit.

[0015] During the downward movement of the vertical block, the vertical block simultaneously drives multiple lifting blocks to move downward, and the lifting block drives the transverse block to move synchronously; the transverse block drives the auxiliary block to move obliquely downward along the path of the inclined groove, so that the transverse block moves to the right relative to the lifting block in the transverse groove, and the transverse block squeezes the bottom block to move to the right. At the same time, the bottom block moves upward relative to the transverse block in the top groove; during the rightward movement of the bottom block, the bottom block drives the slider to move to the right.

[0016] Furthermore, the stopping unit includes a first wedge block fixed to the vertical block and a side groove opened on the side wall of the box body, and a stopping groove is provided on the side wall of the first wedge block; a second wedge block for being squeezed by the first wedge block is slidably connected in the side groove, and a second spring is provided between the second wedge block and the box body, and the second wedge block slides in cooperation with the stopping groove.

[0017] Through the above arrangement, the vertical block is pressed to move downward, so that the first spring is compressed; during the downward movement of the vertical block, the vertical block drives the first wedge block to move downward, the first wedge block squeezes the second wedge block to move to the right, and the second spring is stretched; the vertical block continues to move downward, so that the second wedge block is against the side wall of the first wedge block; the vertical block moves downward again, so that the second wedge block is horizontally opposite to the stop groove, and the second wedge block moves to the left under the action of the second spring, that is, the second wedge block slides into the stop groove, thereby achieving the stopping of the first wedge block, and then achieving the stopping of the vertical block, that is, achieving the positioning of the vertical block.

[0018] Furthermore, the linkage portion includes a first gear coaxially connected to the rotating shaft, a first rack fixed to both sides of the slider, and the first rack meshes with the first gear.

[0019] Through the above arrangement, during the lateral movement of the slider, the slider drives the first rack to move synchronously, so that the first rack engages with the first gear to drive the rotating shaft to rotate, and the rotating shaft drives the limit plate to rotate. When positioning the vertical block, the limit plate abuts against the upper end of the photovoltaic panel, thereby achieving tight contact with the photovoltaic panel, that is, achieving positioning of the photovoltaic panel.

[0020] Furthermore, it also includes several sealing plates for sealing the openings, and linkage rods are provided on both sides of the sealing plates; through holes are provided on both sides of the placement plate, and the end of the linkage rod away from the sealing plate passes through the through holes and is fixed to the transverse block, and the linkage rod can move horizontally and vertically in the opening and the through hole.

[0021] Through the above arrangement, when the horizontal block moves obliquely downward along the path of the inclined groove through the auxiliary block, the horizontal block drives the linkage rod to move obliquely downward in the opening and through hole, and the linkage rod drives the sealing plate to move synchronously. When the vertical block is positioned, the sealing plate is against the box body, and the sealing plate completely seals the opening, thereby realizing sealed storage of the photovoltaic panel, thereby preventing external factors from damaging the photovoltaic panel and preventing the photovoltaic panel from being stained with dust.

[0022] Furthermore, a circular shaft is rotatably connected to the placement plate, a second gear and a cam for abutting against the top of the placement plate are coaxially connected to the circular shaft, and a second rack is provided on the bottom block, which is engaged with the second gear.

[0023] Through the above arrangement, when the bottom block moves to the right, the bottom block drives the second rack to move to the right, the second rack engages with the second gear to drive the circular shaft to rotate, and the circular shaft drives the cam to rotate. When the vertical block is positioned, the raised part of the cam is against the top of the photovoltaic panel, thereby pressing the photovoltaic panel and enhancing the positioning effect of the photovoltaic panel.
