Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic pallets, and in particular to a photovoltaic pallet. Background Art

[0002] Photovoltaic glass, also known as "photovoltaic glass", is a special glass that has a solar photovoltaic mechanism pressed into it, can use solar radiation to generate electricity, and has related current lead-out devices and cables. It is composed of glass, solar cells, film, back glass, special metal wires, etc. It is one of the most innovative high-tech glass products for construction. It can withstand wind pressure and large temperature differences between day and night. It has the advantages of beautiful appearance, controllable light transmittance, energy-saving power generation, no need for fuel, no exhaust gas, no waste heat, no waste residue, and no noise pollution. It is widely used, such as solar smart windows, solar pavilions and photovoltaic glass building roofs, as well as photovoltaic glass curtain walls. It is divided into two categories: crystalline silicon photovoltaic glass and thin-film photovoltaic glass. The former is further divided into single crystal silicon and polycrystalline silicon, and is often used as curtain wall material.

[0003] Currently, photovoltaic glass is primarily transported on traditional wooden and metal pallets. These pallets are fitted with simple barriers, which are then placed against the glass and secured with strapping tape. However, because the barriers are not properly secured to the pallets or are poorly secured, the glass can easily shift during transportation, potentially causing collisions or even damage, resulting in a high rate of cargo damage. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of this application is to provide a photovoltaic pallet, which aims to solve the problem that photovoltaic glass is easily displaced during transportation, thereby causing possible damage to the goods.

[0005] The present invention provides a photovoltaic pallet, comprising:

[0006] base;

[0007] Multiple sets of enclosure mechanisms, each of which is detachably mounted on the base and configured to limit the position of the photovoltaic glass along the length and width of the base, each of which comprises two vertically connected enclosure frames; and

[0008] The locking structure is arranged between the base and each of the blocking frames, and is used to lock the blocking frame and the base in the vertical and horizontal directions. The locking structure includes a locking hole and a rotating shaft hole which are arranged on the top of the base and are connected to each other, and a rotating shaft arranged on the blocking frame and rotatable along its own axis.

The top end of the rotating shaft has a flat position portion, and the outer wall of the flat position portion is covered with a horizontally arranged rotating plate, the top of the blocking frame is provided with a recessed portion, and the bottom of the base is correspondingly provided with a positioning portion that cooperates with the recessed portion. When a plurality of the anti-swaying photovoltaic trays are stacked, the positioning portion is correspondingly arranged in the recessed portion; wherein

[0009] When the protrusion enters the base and the protrusion and the locking hole are offset in the horizontal direction, the retaining frame and the base are locked in the vertical direction and the horizontal direction;

[0010] When the protrusion is completely within the projection range of the locking hole in the vertical direction, the retaining frame and the base are unlocked.

[0011] The locking mechanism secures each retaining bracket to the base more securely when locked, preventing displacement between the retaining bracket and the base during transport, thereby protecting the photovoltaic glass from damage during transport. The locking mechanism is simple in design and low in production cost. The locking mechanism is easy to operate, facilitating the installation and securing of the retaining bracket to the base and improving the efficiency of installing and removing the photovoltaic pallet during loading and unloading.

DETAILED DESCRIPTION

[0032] To facilitate understanding of the present application, a more comprehensive description of the present application will be provided below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present application.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0034] This embodiment provides a photovoltaic pallet, such as Figures 1 to 9As shown, a photovoltaic pallet for carrying and transporting photovoltaic glass includes a base 1, a locking structure, and multiple sets of retaining mechanisms. The retaining mechanism is detachably mounted on the top edge of the base 1 and is used to limit the photovoltaic glass along the length and width of the base 1 to prevent it from sliding off the top of the base 1. The retaining mechanism includes two vertically connected retaining frames 21. Exemplarily, there are four sets of retaining mechanisms, each of which is mounted at the four corners of the base 1. The corners formed between the two retaining frames 21 in each set are correspondingly mounted at the top corners of the base 1. Exemplarily, the corners formed between the two retaining frames 21 in each set are provided with cylindrical pins extending into the top of the base 1, which can limit the position of the retaining frames 21 and the base 1 in the horizontal direction. The locking structure is disposed between the base 1 and each retaining frame 21, that is, each retaining frame 21 is provided with a locking structure between the base 1, and the locking structure is used to lock the retaining frame 21 and the base 1 in the vertical and horizontal directions. The locking structure includes a locking hole 112 and a rotating shaft hole 111 that extend through the thickness of the top of the base 1 and are interconnected, as well as a rotating shaft 31 that is rotatably arranged on the retaining frame 21 along its own axis. The rotating shaft 31 is arranged vertically, and the lower end of the rotating shaft 31 passes through the bottom of the retaining frame 21. A protrusion 32 is provided on the outer wall of the lower end of the rotating shaft 31. The lower end of the rotating shaft 31 and the protrusion 32 can enter and exit the locking hole 112. Exemplarily, the retaining frame 21 includes two vertically arranged vertical beams and two horizontally arranged horizontal beams. The two vertical beams and the two horizontal beams are connected end to end to form a rectangular retaining frame 21. The horizontal beam at the bottom is the first horizontal beam 211. The lower end of the rotating shaft 31 passes through the first horizontal beam 211 in a vertical direction from the top of the first horizontal beam 211 and passes through the bottom of the first horizontal beam 211. A sleeve 36 is mounted on the top outer wall of the rotating shaft 31. A step is provided on the top outer wall of the sleeve 36. A first pad 34 is positioned between the step and the top of the first crossbeam 211. The right end of the first pad 34 is mounted on the outer wall of the sleeve 36 and positioned between the step and the top of the first crossbeam 211. The bottom of the first pad 34 abuts the top of the first crossbeam 211, and the top of the first pad 34 abuts the step. The step prevents the rotating shaft 31 from sliding downward from the first crossbeam 211. The rotating shaft 31 can rotate along its own axis within the first crossbeam 211. A protrusion 32 is provided on the lower outer wall of the rotating shaft 31. When the rotating shaft 31 is fully inserted into the first crossbeam 211, the protrusion 32 is positioned below the bottom of the retaining frame 21. The lower end of the rotating shaft 31 can enter and exit the rotating shaft hole 111, and the lower end of the rotating shaft 31 enters and exits the base 1 through the rotating shaft hole 111. The protrusion 32 can enter and exit the locking hole 112 , and the protrusion 32 enters and exits the base 1 through the locking hole 112 .When the lower end of the rotating shaft 31 enters the base 1 through the rotating shaft hole 111, and the rotating shaft 31 rotates until the protrusion 32 enters the base 1 through the locking hole 112, the rotating shaft 31 is rotated again, so that the protrusion 32 and the locking hole 112 are offset in the horizontal direction, that is, the protrusion 32 is not completely within the vertical projection range of the locking hole 112, that is, the protrusion 32 and the locking hole 112 are not aligned, and the retaining frame 21 and the base 1 are locked in the vertical and horizontal directions. At this time, the rotating shaft 31 inserted into the base 1 can lock the retaining frame 21 and the base 1 in the horizontal direction. When the retaining frame 21 moves upward, the top of the protrusion 32 abuts against the bottom wall of the locking hole 112, preventing the rotating shaft 31 from withdrawing from the base 1, thereby locking the retaining frame 21 and the base 1 in the vertical direction. When the shaft 31 rotates so that the protrusion 32 is completely within the vertical projection of the locking hole 112, that is, the protrusion 32 is aligned with the locking hole 112, the protrusion 32 can exit the locking hole 112, and the shaft 31 can also completely exit the base 1, thereby unlocking the retaining frame 21 and the base 1 in the vertical and horizontal directions. The top of the shaft 31 has a flat portion 311, and the outer wall of the flat portion 311 is covered with a horizontally arranged rotating plate 33. The right end of the rotating plate 33 has an opening that fits on the flat portion 311, and the shape of the hole matches the flat portion 311. The left end is connected to the top of the first pad 34 via a latch 35. The rotating plate 33 facilitates the rotation of the shaft 31, thereby facilitating the locking and unlocking of the retaining frame 21 and the base 1. A recessed portion 5 is provided at the top of the retaining frame 21, and a corresponding positioning portion 6 is provided at the bottom of the base 1 to cooperate with the recessed portion 5. When multiple anti-movement photovoltaic trays are stacked vertically, the positioning portion 6 is correspondingly provided in the recessed portion 5. For example, the recessed portion 5 includes a groove provided at the top of the retaining frame 21; or, two positioning blocks 51 are provided at the top of the retaining frame 21, with a groove portion formed between the two positioning blocks 51. The positioning portion 6 includes a fixing block or protrusion that cooperates with the recessed portion 5. The positioning block 51 and the fixing block can be made of metal. Metal materials have better rigidity and can improve the stability between the anti-movement photovoltaic trays.

[0035] This embodiment utilizes a locking mechanism to more securely secure each retaining frame 21 to the base 1 during locking, preventing displacement between the retaining frame 21 and the base 1 during transport, thereby protecting the photovoltaic glass from damage during transport. The locking mechanism is simple in design and low in production cost. The locking mechanism is easy to operate, facilitating the installation and securing of the retaining frame 21 to the base 1 and improving the efficiency of photovoltaic pallet installation and removal during loading and unloading.

[0036] In one embodiment, Figures 3 to 6 As shown, the top edge of the base 1 is surrounded by four base 1 beams connected end to end, and the locking hole 112 and the shaft hole 111 are respectively provided on the top of the base 1 beams.

[0037] In one embodiment, Figure 5 and Figure 6 As shown, a second pad 37 is provided between the bottom of the first beam 211 and the beam of the base 1 , and a hole having the same shape and size as the locking hole 112 and the shaft hole is correspondingly provided on the second pad 37 .

[0038] In one embodiment, Figure 8 As shown, the lower end of the rotating shaft 31 is provided with a radially extending fixing hole 312. Specifically, the portion of the rotating shaft 31 that extends beyond the bottom of the retaining frame 21 is provided with a radially extending fixing hole 312. A cylinder is inserted into the fixing hole 312, and the portion of the cylinder that extends beyond the fixing hole 312 forms a raised portion 32. Specifically, the cylinder and the fixing hole 312 form an interference fit. This arrangement provides a simple structure, facilitates manufacturing, and reduces production costs.

[0039] In one embodiment, the cylinder is detachably mounted on the rotating shaft 31 .

[0040] In one embodiment, Figure 9 As shown, the outer wall of the cylinder is provided with a notch 321 extending along the cylinder's axial direction, oriented in the length or width direction of the base 1. Specifically, notch 321 is provided on the left and right sides or the top of the outer wall of the cylinder. The provision of notch 321 ensures that when the cylinder exits the locking hole 112, the circumferential ends of notch 321 interfere with the locking hole 112, preventing the cylinder from exiting the locking hole 112 and improving the locking effect between the retaining frame 21 and the base 1.

[0041] In one embodiment, the locking hole 112 comprises a rectangular elongated hole, and the outer diameter of the cylinder is smaller than the width of the locking hole 112 .

[0042] In one embodiment, the two ends of the cylinder correspond to the two ends of the fixing hole 312, and a locking hole 112 is respectively provided on the left and right sides of a shaft hole 111. The above arrangement can improve the locking effect.

[0043] In one embodiment, Figure 1 As shown, a first connector 41 is detachably provided between two opposing retaining frames 21 arranged along the width direction of the base 1. In other words, a first connector 41 is detachably provided between two opposing retaining frames 21 arranged along the length direction of the base 1. Specifically, the two ends of the first connector 41 are respectively provided on the top of the two retaining frames 21 to avoid affecting the placement of the photovoltaic glass. In addition, the first connector 41 is connected to the end of the two retaining frames 21 away from the adjacent retaining frames 21, which provides a better fixing effect between the two retaining frames 21. Exemplarily, the first connector 41 is a hollow metal member, and its cross-section can be rectangular, circular, or triangular, which is not limited here.

[0044] In one embodiment, the anti-movement photovoltaic tray further includes multiple second connectors 42. The first end of each second connector 42 is detachably connected to the first connector 41, and the second end is detachably connected to a corresponding retaining frame 21 arranged along the width of the base 1. Specifically, each retaining frame 21 arranged along the width of the base 1 corresponds to a second connector 42. The first end of the second connector 42 is connected to the middle portion of the first connector 41, and the second end is connected to the adjacent ends of two adjacent retaining frames 21 along the width of the base 1. The first connector 41 and the second connector 42 are arranged perpendicularly in the horizontal direction. This arrangement can improve the connection stability between the retaining frames 21.

[0045] In one embodiment, Figure 2 As shown, a plurality of anti-slip pads 7 are provided at the bottom of the base 1. Specifically, the anti-slip pads 7 are evenly distributed along the length and width directions of the bottom of the base 1 to improve the anti-slip effect of the base 1 and avoid damage to the photovoltaic glass due to movement of the anti-movement photovoltaic pallet during transportation.

[0046] In one embodiment, the two retaining frames 21 are hinged and can be rotated along the hinge point until the two retaining frames 21 are stacked, so that the retaining frames 21 can be easily removed from the base 1 and stored.

[0047] In one embodiment, the interior of the base 1 is provided with a storage space for accommodating the retaining frame 21. For example, the storage space comprises a rectangular opening on the outer wall of the base 1, arranged along the length or width of the base 1. This arrangement allows for storage of the folded retaining frame 21, facilitating stacking of unused bases 1 and preventing loss of the retaining frame 21 corresponding to each photovoltaic tray.

[0048] In one embodiment, a horizontally pull-out drawer is provided in the accommodating space, and the retaining frame 21 can be stored in the drawer, so as to facilitate the storage of the retaining frame 21 .

[0049] It should be understood that the application of the present invention is not limited to the above examples. For those skilled in the art, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
