Description

Technical Field

[0001] This utility model belongs to the technical field of logistics packaging and transportation equipment, specifically relating to a pressure-resistant photovoltaic module wooden pallet with a wood strip design structure. Background Technology

[0002] In the warehousing and transportation of photovoltaic modules, wooden pallets with a slatted design are the core tool for supporting the modules. They provide stable support for the photovoltaic modules through a combination of bottom slats, wooden blocks, and top supporting slats. However, in actual use, traditional wooden pallets often suffer from performance defects in the unsupported areas (i.e., the parts without direct support between adjacent wooden blocks) due to unreasonable stress distribution. Specifically, photovoltaic modules are heavy, and the load is concentrated on the supporting slats during stacking or bumpy transport. Because the supporting slats of traditional pallets are only supported by wooden blocks at both ends, the unsupported middle section lacks additional support structure. After long-term loading, the unsupported area is prone to bending deformation due to stress concentration. If subjected to sudden braking, collisions, or other instantaneous impacts, the bending degree at the unsupported area will increase dramatically, even leading to breakage. Furthermore, perforations on the supporting slats (such as holes for fixing or adjustment) left unused for a long time become structural weak points, further increasing the risk of breakage at the unsupported area. The wood fibers around the holes are cut, making them prone to cracking from the holes under stress, leading to the failure of the entire supporting slat. Utility Model Content

[0003] The purpose of this utility model is to provide a pressure-resistant photovoltaic module wooden pallet with a wooden strip design structure to solve the problems mentioned in the background art, such as the large self-weight of photovoltaic modules, the concentrated load on the wooden strips when stacked or transported, the lack of additional support at the suspended parts with only square blocks at both ends, the tendency to bend and deform under long-term load, and even break directly when subjected to impact forces such as sudden braking.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant photovoltaic module wooden pallet with a wooden strip design, comprising a bottom strip B and a bottom strip C symmetrically arranged on the left side of the bottom strip B, a bottom strip A symmetrically arranged on the right side of the bottom strip B, multiple wooden blocks A equidistantly arranged at the top of the bottom strip A, multiple wooden blocks B equidistantly arranged at the top of the bottom strip B, and multiple wooden blocks C equidistantly arranged at the top of the bottom strip C. A top strip is connected to the top of each of the wooden blocks A, B, and C. Multiple load-bearing wooden strips are equidistantly connected to the tops of the three top strips. Suspension support devices are provided on both sides of the center of the bottom of each load-bearing wooden strip, and these suspension support devices are located between wooden blocks A and B, and between wooden blocks B and C, respectively.

[0005] Preferably, the suspension support device includes a baffle with an embedded circular hole, an embedded baffle, a stud through hole, and a hard plastic thickened stud. The center of the supporting wooden strip has stud through holes on both the left and right sides. The upper half of each stud through hole is connected to the baffle with an embedded circular hole. A hard plastic thickened stud is inserted into each stud through hole. The top of each hard plastic thickened stud has an embedded baffle integrally formed, and the embedded baffle is embedded in the baffle with an embedded circular hole.

[0006] Preferably, the suspension support device further includes a thickened hard plastic mounting plate, a hard plastic rotating nut, and a hard plastic internally threaded support cylinder. The bottom end of the hard plastic thickened stud is exposed below the bottom outer wall of the supporting wooden strip. The hard plastic thickened stud is threaded with a hard plastic internally threaded support cylinder, which is located at the bottom of the supporting wooden strip. The top circular outer wall of the hard plastic internally threaded support cylinder is integrally formed with a hard plastic rotating nut, and the bottom end of the hard plastic internally threaded support cylinder is integrally formed with a thickened hard plastic mounting plate.

[0007] Preferably, the hard plastic rotating nut can drive the hard plastic internal thread support cylinder to rotate clockwise and counterclockwise outside the bottom end of the hard plastic thickened stud. When the hard plastic rotating nut and the top of the hard plastic internal thread support cylinder are attached to the bottom outer wall of the supporting wooden strip, the thickened hard plastic mounting plate is flush with the bottom outer wall of the bottom strips A, B and C of the pallet.

[0008] Preferably, after the hard plastic internal thread support cylinder detaches from the outside of the hard plastic thickened stud, the embedded baffle can drive the hard plastic thickened stud to be pulled upward from the stud through hole. After the embedded baffle is embedded in the inner hole of the baffle, the embedded baffle is flush with the outer wall of the top of the supporting wooden strip.

[0009] Preferably, the pallet wooden block A is fixedly connected to the pallet bottom strip A and the pallet top strip, the pallet wooden block B is fixedly connected to the pallet bottom strip B and the pallet top strip, and the pallet wooden block C is fixedly connected to the pallet bottom strip C and the pallet top strip by multiple pointed screws.

[0010] Preferably, the multiple supporting wooden strips are fixedly connected to the three tray top strips by multiple pointed screws, and the multiple supporting wooden strips can be fixed in various directions at the top of the three tray top strips according to different photovoltaic module sizes and placement requirements.

[0011] Preferably, the supporting wooden strips are made of plywood.

[0012] Compared with the prior art, this utility model provides a pressure-resistant photovoltaic module wooden tray with a wood strip design structure, which has the following beneficial effects:

[0013] This invention adds novel support devices to both sides of the center of multiple supporting wooden slats to address any gaps in the support structure. These devices provide targeted support for the suspended sections of the slats. Through the cooperation of thickened hard plastic studs and internally threaded hard plastic support cylinders, the support height can be flexibly adjusted, ensuring the thickened hard plastic mounting tray fits tightly against the bottom slats. This disperses the pressure of the photovoltaic modules on the supporting wooden slats, preventing bending or breakage due to excessive stress at the gaps, significantly improving the overall pressure resistance of the tray. Furthermore, the device features an embedded design, with the hard plastic components highly adaptable to the wooden structure. It does not affect the arrangement of the supporting wooden slats and allows for flexible adjustment of the support position according to the module size. Simultaneously, the hard plastic material is wear-resistant and corrosion-resistant, and the detachable structure facilitates installation, maintenance, and component replacement, extending the tray's lifespan and reducing operating costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-4 The diagram shows a pressure-resistant photovoltaic module pallet with a wood strip design. It includes a bottom strip B6 and two bottom strips C7 symmetrically positioned to the left of the bottom strip B6. A bottom strip A1 is symmetrically positioned to the right of the bottom strip B6. Multiple wooden blocks A2 are equidistantly positioned at the top of bottom strip A1. Multiple wooden blocks B8 are equidistantly positioned at the top of bottom strip B6. Multiple wooden blocks C9 are equidistantly positioned at the top of bottom strip C7. The tops of the wooden blocks A2, B8, and C9 are also connected. Each end is connected to a top slat 3 of the pallet. Multiple load-bearing wooden strips 4 are equidistantly connected to the top of the three top slats 3. The load-bearing wooden pallets of the pressure-resistant photovoltaic modules are evenly distributed above the wooden block of the pallet and the top slats 3 of the pallet through the load-bearing wooden strips 4. The spacing between adjacent load-bearing wooden strips 4 is reserved within a reasonable range to form a multi-point distributed load-bearing system. The evenly distributed load-bearing wooden strips 4 can distribute the weight of the photovoltaic modules to multiple support points to avoid local overload. The spacing design not only ensures the stability of the modules when placed, but also reserves ventilation channels to reduce the aging of the wood material caused by moisture and heat accumulation, taking into account both load-bearing strength and environmental adaptability.

[0021] like Figure 1 and Figure 2As shown, the wooden block A2 of the pallet is fixedly connected to the bottom slat A1 and top slat 3 of the pallet, the wooden block B8 is fixedly connected to the bottom slat B6 and top slat 3 of the pallet, and the wooden block C9 is fixedly connected to the bottom slat C7 and top slat 3 of the pallet using multiple pointed screws. Multiple supporting wooden strips 4 are also fixedly connected to the three top slats 3 of the pallet using multiple pointed screws. Furthermore, the multiple supporting wooden strips 4 can be arranged in various directions at the top of the three top slats 3 according to different photovoltaic module sizes and placement requirements. The supporting wooden strips 4 can be arranged horizontally, vertically, or in combination, depending on the size of the photovoltaic modules and placement requirements. The layout can be flexibly adjusted according to the needs. This multi-directional arrangement design breaks the limitations of fixed structures. By changing the combination of the load-bearing wooden strips 4, it can adapt to different specifications of components, realizing the application of "one pallet for multiple scenarios". At the same time, with the support and positioning of the pallet's wooden blocks and the top strips 3, it ensures that the load-bearing wooden strips 4 are evenly stressed under different arrangements, maintaining the overall compressive strength of the pallet. The load-bearing wooden strips 4 are made of plywood, and their material characteristics are suitable for the erosion that may be faced in outdoor or warehouse environments, such as humidity, heat and insect infestation. The specifications of the wooden strips are designed according to the overall size of the pallet and the load-bearing requirements. While ensuring sufficient mechanical strength to support the weight of the components, it avoids material waste and increased pallet weight due to excessively thick or coarse specifications.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, multiple supporting wooden planks 4 have suspended support devices 5 on both sides of the center of their bottom ends. These suspended support devices 5 are located between pallet wooden blocks A2 and B8, and between pallet wooden blocks B8 and C9, respectively. Each suspended support device 5 includes a baffle with an embedded round hole 12, an embedded baffle 14, a stud hole 15, and a hard plastic thickened stud 16. Stud holes 15 are provided on both sides of the center of the supporting wooden planks 4. The upper half of each stud hole 15 is connected to the baffle with an embedded round hole 12, and a hard plastic thickened stud is inserted into each stud hole 15. The two thickened hard plastic studs 16 are integrally formed with embedded baffles 14 at their top ends. The embedded baffles 14 are embedded in the embedded round holes 12 of the baffles. The device is fixedly connected to the stud holes 15 of the supporting wooden strip 4 through the thickened hard plastic studs 16. After the embedded baffles 14 are inserted into the embedded round holes 12 of the baffles, they are flush with the top of the wooden strip, forming a "non-removable" installation structure. This design ensures that the device is always installed at the bottom of the supporting wooden strip 4, avoiding the stud holes 15 from being left empty due to disassembly, preventing the holes from becoming weak points in the structure, fundamentally eliminating the risk of the wooden strip breaking easily when there are no inserts, and ensuring the continuity of support.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, the suspended support device 5 also includes a thickened hard plastic mounting plate 10, a hard plastic rotating nut 11, and a hard plastic internally threaded support cylinder 13. The bottom end of the hard plastic thickened stud 16 is exposed below the bottom outer wall of the supporting wooden strip 4. The hard plastic thickened stud 16 is threaded onto the hard plastic internally threaded support cylinder 13, and the hard plastic internally threaded support cylinder 13 is located at the bottom of the supporting wooden strip 4. The top circular outer wall of the hard plastic internally threaded support cylinder 13 is integrally formed with a hard plastic rotating nut 11, and the bottom end of the hard plastic internally threaded support cylinder 13 is integrally formed with a hard plastic rotating nut 11. The molded thickened hard plastic placement tray 10, with a hard plastic rotating nut 11, can drive the hard plastic internally threaded support cylinder 13 to rotate clockwise and counterclockwise outside the bottom end of the hard plastic thickened stud 16. When the top of the hard plastic rotating nut 11 and the hard plastic internally threaded support cylinder 13 are attached to the bottom outer wall of the supporting wooden strip 4, the thickened hard plastic placement tray 10 is flush with the bottom outer walls of the bottom strips A1, B6, and C7 of the pallet. Utilizing the threaded engagement between the hard plastic internally threaded support cylinder 13 and the hard plastic thickened stud 16, the tray is rotated... The rigid plastic rotating nut 11 adjusts the support height, ensuring the thickened rigid plastic mounting plate 10 fits tightly against the bottom slats of the pallet. This adjustability adapts to different clearances, ensuring precise force distribution at the support point. It transfers the pressure from the suspended portion of the wooden slats 4 to the bottom slats, dispersing localized loads and improving the slats' resistance to bending and breakage. After the rigid plastic internally threaded support cylinder 13 detaches from the rigid plastic thickened stud 16, the embedded baffle 14 can pull the rigid plastic thickened stud 16 upwards from the stud hole 15. After the baffle 14 is embedded into the inner hole 12, the embedded baffle 14 is flush with the top outer wall of the supporting wooden strip 4. The device uses hard plastic material to make studs, support cylinders, nuts and other components. Its combination of rigidity and toughness can not only withstand the weight load of photovoltaic modules, but also buffer the vibration and impact during transportation or stacking. At the same time, the hard plastic material is moisture-resistant and corrosion-resistant, which complements the weather resistance of the plywood strips, adapting to the complex environment in warehousing and transportation, and extending the overall service life of the device and the pallet.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
