Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component transport equipment, and more specifically, to a photovoltaic wooden pallet with an expansion function. Background Art

[0002] With the development of the photovoltaic industry, improving the conversion efficiency of photovoltaic products has become the key to improving product competitiveness, and higher requirements have been placed on the testing of produced photovoltaic modules. When testing and calibrating photovoltaic modules, standard modules need to be used to calibrate the test instruments. In the industry, standard modules generally use primary and secondary standard plates. Modules calibrated by an authoritative third-party certification agency are used as primary standard plates, which are used as a benchmark to copy secondary standard plates for daily testing.

[0003] When customers need to conduct standard tests on the photovoltaic modules they purchased, they often need to use a separate wooden box to transport the standard modules. The standard module wooden box not only takes up transportation space, but also the cost of customized wooden boxes is high. If cardboard boxes are used for packaging, there is often a risk of collision and damage to the standard modules.

[0004] Chinese patent document CN 220640641 U discloses a tray for supporting photovoltaic modules, including a supporting body and a plurality of supporting bars, wherein the supporting body is provided with a supporting portion, and the plurality of supporting bars are detachably connected to the supporting body along the supporting portion; the density of the plurality of supporting bars located on both sides of the supporting body is greater than the density of the plurality of supporting bars located in the middle of the supporting body.

[0005] In the prior art, there is no space for placing standard components separately in the transfer pallet of photovoltaic modules. Often, a separate wooden box is needed to transport the reference standard parts. The standard component wooden box not only takes up transportation space, but also the customized wooden box is expensive. If cardboard packaging is used, there is often a risk of collision and damage to the reference standard parts, which in turn affects the accuracy of module testing. At the same time, the production cycle of standard reference parts is long and the cost is high, and damage will affect the construction period of the project.

[0006] Therefore, it is necessary to propose a photovoltaic wooden pallet with expansion function to solve the problems existing in the prior art. Utility Model Content

[0036] A plurality of load-bearing strips 3 are evenly arranged along the length direction of the upper support plate 11 .

[0037] The protective plate 15 is hingedly connected to the load-bearing strip 3 via a hinge 16 .

[0038] A protective buffer layer 17 is provided on the lower surface of the upper support plate 11 , the upper surface of the lower support plate 12 and the side surfaces of the supporting wooden strips 13 in the accommodating cavity 14 . The material of the protective buffer layer 17 is foam.

[0039] Three supporting legs 2 are provided, and the supporting legs 2 are evenly distributed along the width direction of the lower supporting plate 12. The supporting legs 2 include a pad 21 and a longitudinal beam 22. The pad 21 is fixedly provided on the lower surface of the lower supporting plate 12, and a plurality of pads 21 are evenly provided along the length direction of the lower supporting plate 12. The longitudinal beam 22 is fixedly connected to the lower surfaces of the plurality of pads 21, and the length of the longitudinal beam 22 is consistent with the length of the lower supporting plate 12.

[0040] The support wood strips 13 are made of solid wood or plywood. The length of the support wood strips 13 is consistent with that of the upper support plate 11 and the lower support plate 12, and the height is 35-50 mm.

[0041] The upper support plate 11 and the lower support plate 12 are made of plywood or solid wood board with a thickness of 5 to 10 mm.

[0042] A notch 18 is formed at the lower edge of the outer side of the protection plate 15 .

[0043] The working principle of the above technical solution is as follows: the lower support plate 12 mainly supports the photovoltaic standard components, the upper support plate 11 mainly protects the photovoltaic standard components, the support wood strips 13 mainly support and form a receiving cavity 14 for receiving the photovoltaic standard components, the width of the support wood strips is consistent with the width of the cushion block 21, and the outer sides of the two support wood strips 13 are respectively aligned with the two side surfaces of the upper support plate 11. A plurality of load-bearing strips 3 are arranged on the upper surface of the upper support plate 11 along the length direction of the upper support plate 11, and the load-bearing strips 3 at the front and rear ends are respectively aligned with the front and rear ends of the receiving box 1, so as to facilitate the installation of the hinge 16, which is connected to the load-bearing strips 3 and the protective plate 15 by screws.

[0044] The load-bearing slats 3 are made of solid wood or plywood, and their main function is to provide support for the goods on the pallet and protect the container 1. The thickness of the load-bearing slats 3 needs to be increased and set to 12 to 16 mm. The length is consistent with the width of the upper support plate 11, and the width is set to 90 to 120 mm. Multiple load-bearing slats 3 are evenly distributed, and the spacing range is 90 to 120 mm, which can be confirmed according to actual conditions.

[0045] The protective plate at the front end of the storage box 1 is hinged to the side of the frontmost load-bearing strip 3 through a hinge 16, and the protective plate at the rear end is hinged to the side of the rearmost load-bearing strip 3 through a hinge 16.

[0046] The upper support plate 11 and the lower support plate 12 are of the same size and are arranged in parallel. The upper and lower walls and the side walls of the accommodating cavity are fixedly provided with a protective buffer layer 17, which is used to protect the photovoltaic standard components. The protective buffer layer can be provided to be detachably connected to the inner wall of the accommodating cavity 14, so as to facilitate the replacement of the protective buffer layer 17. Velcro can be provided between the inner wall of the accommodating cavity 14 and the protective buffer layer 17, so as to facilitate the replacement of the protective buffer layer. The material of the protective buffer layer is foam, which can be selected from polyurethane foam, polyethylene foam or rubber foam, or other foam can be selected according to the transportation conditions.

[0047] The legs 2 provide a space for inserting and transporting the pallet. Three legs 2 are evenly arranged along the lower surface of the lower support plate. The positions of the two outer legs are opposite to the positions of the two supporting wooden strips 13, and the middle leg is located in the middle of the legs on both sides. The legs include a plurality of pads 21 arranged in a straight line along the length direction of the support plate 12, and the longitudinal beams 22 are fixedly arranged on the lower surfaces of the plurality of pads 21.

A protective buffer layer is provided on the side wall of the protective plate 16 close to the storage cavity, which is consistent with the protective buffer layer provided in the storage cavity 14.

[0049] When the goods are packed outside during transportation, the protective plate 15 is fixed simultaneously (such as Figure 5 As shown), the strapping belt 19 bundles the goods on the pallet and the protective plate at the same time, which is easy to operate.

[0050] Beneficial effects of the above technical solution:

[0051] The photovoltaic wooden pallet with expansion function described in the utility model can save a special wooden box in the process of transporting photovoltaic standard components, and can reduce the space and weight of a wooden box. Under the condition of the same container space, the pallet can carry more goods and the transportation cost is lower. In addition to transporting photovoltaic standard components, the containing cavity can also be used for the transportation of other precision instruments and components, and has an expansion function, which increases the applicability of the pallet.

[0052] In one embodiment, Figure 6-8 As shown, when the photovoltaic standard components are loaded into the containing box 1, it is necessary to lift the protective plate and keep the protective plate 15 in a horizontal position to prevent collision with the photovoltaic standard components, which increases the difficulty of loading the photovoltaic standard components. Therefore, a protective plate support assembly is provided to support the protective plate 15 in a horizontal position when the photovoltaic standard components are loaded into the containing box 1, so as to facilitate the loading of the photovoltaic standard components. The protective plate support assembly includes a support rod 30, which includes a vertical rod and a first cross head 301 and a second cross head 302 fixed at both ends of the vertical rod and perpendicular to the vertical rod. The first cross head 301 of the support rod 30 is rotatably connected to an end face of the protective plate 15, and a first groove 31 is provided on the end face of the supporting wooden strip 13 on one side of which the support rod 30 is installed. A heart-shaped groove 32 is provided on the inner wall of the first groove 31 on the side close to the accommodating cavity 14. The second cross head 302 of the support rod 30 is slidably arranged in the heart-shaped groove 32, and a second groove 33 is provided on the inner wall of the first groove 31 and penetrates the accommodating cavity 14 at a distance from the heart-shaped groove 32. The position of the second groove 33 corresponds to the position of one end of the support rod 30 rotatably connected to the protective plate when the protective plate is in a vertical state, and is used to accommodate one C-shaped end of the support rod when the protective plate 15 is lowered and is in a vertical state.

[0053] The heart-shaped groove 32 includes a first straight groove 34, a second straight groove 35 and an arc groove 36. One end of the first straight groove 34 and the second straight groove 35 are respectively connected to the two ends of the arc groove 36. The arc of the arc groove 36 is bent toward the first straight groove 34 and the second straight groove 35. The other end of the first straight groove 35 is connected to the middle of the second straight groove 35. The second straight groove 35 includes a first section 351 and a second section 352. The part where the first straight groove 34 is connected to the second straight groove 35 is located at the connection between the first section 351 and the second section 352. The width of the second section 352 of the second straight groove 35 is smaller than the width of the first section 351.

[0054] The working principle of the above technical solution is as follows: in the initial state, when the protective plate 15 is in the vertical position, the second cross head 302 of the support rod 30 extending into the first groove 31 is at the end of the second section 352 of the second linear groove 35. When the protective plate 15 is opened, the protective plate drives the support rod 30 to move, and the cross head 302 slides in the second linear groove 35. Since the width of the first section 351 of the second linear groove 35 is greater than the width of the second section 352, when the protective plate 15 pulls the support rod 30 to move outward, the second cross head 302 of the support rod 30 enters the first section from the second section of the second linear groove 35 and does not enter the first linear groove 34. The second cross head 302 of the support rod 30 is pulled until the second linear groove 35 is connected with the arc groove 36. When the protective plate 15 is in the connected position, it contacts the inclined surface 361 of the arc groove 36, and the first cross head 301 of the support rod 30 is rotatably connected to the lower part of the end surface of the protective plate 15. A circular hole can be opened at the lower part of the protective plate 15, and the first cross head 30 of the support rod 30 is rotatably arranged in the circular hole. The second cross head 302 of the support rod 30 moves downward under the action of the inclined surface 361, so that the support rod 30 rotates. At this time, the protective plate 15 is lowered, and the second cross head 302 of the support rod 30 contacts the side wall of the arc groove 36 close to the second straight groove 35. The support rod 30 continues to rotate under the action of the side wall of the second straight groove 35 until the second cross head 302 of the support rod 30 slides to the arc top of the arc groove 36. At this time, the support rod 30 is at the arc top of the arc groove 36 (such as Figure 7 As shown in the figure, the support rod 30 supports the protective plate 15, so that the protective plate 15 is kept in a horizontal position, which is convenient for loading the photovoltaic standard components into the storage box 1, and no human support is required. After loading the photovoltaic standard components, the protective plate 15 is pulled up, and the second cross head 302 of the support rod 30 contacts the lower half of the arc of the side wall of the arc groove 36 away from the first straight groove 34, so that the second cross head 302 of the support rod 30 continues to move downward, and the protective plate 15 is released after reaching the lowest end of the arc groove. The protective plate 15 rotates along the axis of the hinge under the action of its own gravity, and the protective plate 15 pushes the support rod 30 to move, and the second cross head 302 of the support rod 30 slides along the first straight groove 34 and enters the second section 352 of the second straight groove 35, and the protective plate is closed.
