[0003] As environmental issues receive increasing attention worldwide, the development and utilization of new energy sources have become a future trend. Among them, concentrated solar power (CSP) technology has moved from theory to reality. Currently, the main development directions of new energy are CSP, photovoltaic power, wind power, and hydropower. CSP currently mainly includes parabolic trough and tower solar thermal power generation. Parabolic trough solar thermal power generation can maintain the stability of power generation day and night and is one of the mainstream directions for future new energy development.

[0048] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0049] like Figures 1-14 As shown, the present invention provides an embodiment of a heat collection tube storage and transportation device.

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 7 As shown, the solar collector tube storage and transportation device 100 includes four sets of main uprights (not shown in the attached drawing) vertically mounted on a pallet (not shown in the attached drawing) and a solar collector tube stacking device (not shown in the attached drawing); the pallet includes a pallet frame 8 and load-bearing blocks 9 fixedly connected to the four corners of the bottom of the pallet frame 8. The load-bearing blocks 9 are provided with lifting holes 91, allowing for the direct lifting and transfer of the pallet frame 8 of the solar collector tube storage and transportation device 100 by a forklift, or the entire solar collector tube storage and transportation device 100 can be lifted directly through the lifting holes on the load-bearing blocks 9; the main uprights are two adjacent sets of main uprights 6, and the four sets of main uprights are respectively... The main support column assembly is detachably connected to the four load-bearing piers 9 and is equipped with a guide structure (not shown in the attached figure). The heat collection tube layering device includes at least two heat collection tube fixing brackets 7 and heat collection tubes M for storing the heat collection tubes. The two ends of the heat collection tube fixing brackets 7 can be restricted within the guide structure to restrict the rolling and horizontal movement of the heat collection tubes. Two adjacent heat collection tube fixing brackets 7 can be pinned and aligned with each other. Multiple heat collection tube fixing brackets 7 can be stacked sequentially to allow the heat collection tube layering device to be directly hoisted onto the heat collection tube storage and transportation device 100. Each layer of heat collection tube layering device can slide and align pinned within the guide structure.

[0051] The beneficial effects of this invention are as follows: The solar collector tube storage and transportation device disclosed in this invention includes four sets of main uprights vertically mounted on a pallet and a solar collector tube layering device. It can realize the overall hoisting of the entire solar collector tube storage and transportation device, as well as the hoisting of each layer of solar collector tube layering device to the solar collector tube storage and transportation device. It can also be used with a forklift to lift and transport the solar collector tube storage and transportation device. The solar collector tube layering device includes at least two solar collector tube fixing brackets and solar collector tubes for storing solar collector tubes. The two ends of the solar collector tube fixing brackets can be confined within the guide structure. Two adjacent solar collector tube fixing brackets can be pinned and aligned with each other. Multiple solar collector tube fixing brackets are stacked sequentially, which facilitates the quick docking and stacking of each layer of solar collector tube layering device to the solar collector tube storage and transportation device, and also facilitates the neat and stable placement of multiple solar collector tube transportation devices on the transportation vehicle to achieve batch transportation, thereby improving the reliability of transportation and hoisting efficiency. Meanwhile, the heat collector tube storage and transportation device adopts a detachable structure, which can be disassembled after transportation, reducing the overall transportation volume, saving transportation space, and reducing transportation costs.

[0052] In this embodiment, specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, the pallet includes a pallet frame 8 consisting of multiple intersecting pallet beams (not shown in the attached diagram) connected as a whole, and load-bearing blocks 9 fixedly connected to the four corners of the bottom of the pallet frame 8. The bottom surface of the load-bearing blocks 9 protrudes from the bottom surface of the pallet frame 8. On the one hand, the load-bearing blocks 9 can bear the weight of the entire heat collector tube receiving and transporting device and the weight of all the heat collector tubes it contains, allowing the load-bearing blocks 9 to concentrate the impact and wear on the bottom during transportation and transfer. On the other hand, the bottom of the load-bearing blocks 9 is raised a certain distance above the pallet frame 8, making it easier for forklifts and other transfer tools to directly insert the entire heat collector tube receiving and transporting device 100 from the bottom of the pallet frame 8, thus making it easier for forklifts and other special tools to directly lift the entire heat collector tube receiving and transporting device 100. It should be noted that multiple crisscrossing pallet beams are connected to form a whole pallet frame 8, and load-bearing piers 9 are fixedly connected to the four corners of the bottom of the pallet frame 8. The connection of the multiple pallet beams and the connection of the load-bearing piers 9 to the pallet frame 8 can be achieved by direct welding, fastening with fasteners such as screws and bolts, snap-fitting, or fastening. As long as the technical solution can achieve a stable and reliable connection of multiple pallet beams and a stable and reliable connection of the load-bearing piers 9 to the pallet frame 8, it is within the protection scope of this application, and will not be elaborated here.

[0053] In this embodiment, specifically, such as Figure 1 , Figure 2 , Figure 3As shown, the main support pole group consists of two adjacent main support poles 6. The four main support pole groups are perpendicular to the upper surfaces of the four load-bearing piers 9 and are detachably connected to the load-bearing piers 9. A gap is left between two adjacent main support poles 6 in each group. The width of this gap is approximately equal to the axial thickness of the collector tube fixing bracket 7 in the axial direction of the collector tube it supports. This means the collector tube fixing bracket 7 can move up and down and back and forth within this gap. This gap extends from the bottom where the two adjacent main support poles 6 connect to the load-bearing piers 9 to the top of the two adjacent main support poles 6, forming a guide structure that restricts the movement direction of the collector tube fixing bracket 7. This ensures that after the collector tubes are stacked, there is no large movement space between them and the main support poles. Furthermore, the main support pole 6 can be cylindrical, square, or regular polygonal. Any solution that leaves a gap between two adjacent main support poles 6 to form a guide structure that allows the collector tube fixing bracket 7 to move freely up and down and back and forth is within the scope of protection of this application. On the one hand, the main support rod group consisting of two main support rods 6 with gaps increases the rigidity of the entire heat collector tube receiving and transporting device in the vertical direction. The ability of the main support rod group to resist vertical and horizontal impacts is at least twice that of a single main support rod 6. On the other hand, the guide structure between the two main support rods 6 of the main support rod group further restricts the direction in which the heat collector tube fixing bracket 7 can move freely up, down, back and forth, which facilitates the hoisting of the heat collector tube layered device formed by the pair of heat collector tube fixing brackets 7 after the heat collector tubes are installed onto the heat collector tube receiving and transporting device 100, thus improving the convenience of hoisting.

[0054] In this embodiment, specifically, such as Figure 3 , Figures 5 to 9 As shown, the entire collector tube storage and transportation device 100 can accommodate multiple layers of collector tube stacking devices in the vertical direction. Two adjacent collector tube fixing brackets 7 can be pinned together for alignment and fixation, and multiple collector tube fixing brackets are stacked sequentially. Furthermore, as... Figure 8 , Figure 9 As shown, between the lowest and second-lowest layer of collector tube stacking devices, between the top and second-highest layer of collector tube stacking devices, and between two stacked layers of collector tube stacking devices, each collector tube fixing bracket 7 is provided with a fixing component (not shown in the attached figure) for stacking and fixing the collector tube fixing bracket plate. The fixing component includes a fixing structure on the upper end face (not shown in the attached figure) and a mating structure (not shown in the attached figure) on the lower end face that cooperates with the fixing structure on the upper end face. The fixing structure and mating structure of each collector tube fixing bracket 7 allow the collector tube fixing bracket 7 of the corresponding upper and / or lower layer of collector tube stacking devices to be easily aligned and interlocked, thereby improving the efficiency of stacking multiple collector tube stacking devices in sequence.

[0055] In some embodiments, such as Figure 1 , Figure 6 , Figure 7 , Figure 9 As shown, the collector tube receiving and transporting device 100 also includes a main support rod connecting cover plate 1, which covers the tops of two adjacent sets of main support rods to prevent the collector tube fixing bracket 7 from sliding out from the top of the guide structure. Specifically, as... Figure 7 , Figure 9 As shown, the main support rod connecting cover plate 1 connects the tops of the four main support rods 6 of the two adjacent main support rod groups, which can further prevent the four main support rods 6 from displacing and twisting each other under the action of external force. At the same time, it can also further prevent the top layer of the heat collector tube fixing bracket 7, which has been installed with heat collector tubes, from sliding upward out of the guide structure under the action of external force. Simply put, the main support rod connecting cover plate 1 can restrict the heat collector tube fixing bracket 7 from moving upward, so that when the entire heat collector tube storage and transportation device 100 is subjected to external force impacts from all directions during transportation and transfer, the heat collector tubes M contained in the heat collector tube storage and transportation device 100 will not collide with each other.

[0056] In some embodiments, such as Figure 2 , Figure 3 , Figure 8 , Figure 9 As shown, the collector tube fixing bracket 7 is equipped with a fixing component (not shown in the figure) for stacking and securing the collector tube fixing bracket 7. The fixing component includes an upper end with a fixing structure and a lower end with a mating structure that cooperates with the fixing structure. The mating structure at the lower ends of the upper collector tube fixing bracket 7 allows for automatic positioning and docking of the fixing structures at the upper ends of the lower collector tube fixing bracket 7. This reduces the difficulty of alignment when hoisting the collector tube stacking device onto the collector tube receiving and transporting device 100, lowers the accuracy requirements of the hoisting process, and allows the hoisted upper collector tube stacking device to automatically and accurately align with the lower collector tube stacking device to be stacked, thus improving hoisting efficiency.

[0057] In some embodiments, such as Figure 1 , Figure 2 , Figures 5 to 9 As shown, the guide structure includes a guide groove (not shown in the attached figure) located between the two main uprights 6 of each group of main uprights, and both ends of the heat collection tube fixing bracket 7 can slide within the guide groove. Specifically, as shown... Figure 8 , Figure 9As shown, a gap is left between two adjacent main uprights 6 in each group of main uprights. The width of this gap is equivalent to the thickness of the collector tube fixing bracket 7 in the axial direction of the collector tube it supports. In other words, the collector tube fixing bracket 7 can move up and down and back and forth in this gap. This gap extends from the bottom where the two adjacent main uprights 6 are connected to the load-bearing pier 9 to the top of the two adjacent main uprights 6, forming a guide groove that restricts the movement direction of the collector tube fixing bracket 7. This guide groove helps the two adjacent collector tube fixing brackets 7 to be pinned and aligned with each other. When hoisting the collector tube layer installation, it is not necessary to deliberately align the collector tube fixing brackets 7 of the upper and lower layers of the hoisted collector tube layer installation. First, the guiding effect of the guide groove is used to determine the initial hoisting position of the upper collector tube fixing bracket 7. Then, the mating structure at the lower ends of the upper collector tube fixing bracket 7 (not shown in the figure) is used to achieve further automatic secondary positioning and docking with the fixing structure at the upper ends of the lower collector tube fixing bracket 7 (not shown in the figure). The guiding structure reduces the difficulty of alignment when hoisting the upper layer of collector tubes to the collector tube receiving and transporting device 100, lowers the accuracy requirements of the hoisting process, and allows the upper layer of collector tubes to be hoisted to automatically and accurately align with the lower layer of collector tubes to be stacked, thus improving hoisting efficiency.

[0058] In some embodiments, such as Figure 2 , Figure 3 , Figure 8 , Figure 9 As shown, the fixing structure includes a fixing hole (not shown in the figure), and the mating structure includes a fixing post (not shown in the figure) that can be housed in the fixing hole, the end of which is tapered. Specifically, as... Figure 3 As shown, the upper part of both ends of the collector tube fixing bracket 7 is provided with an upwardly protruding fixing structure, which can be an upper positioning pin 71. The top of the upper positioning pin 71 can be provided with a fixing hole, which can be a blind hole that does not penetrate the end of the collector tube fixing bracket 7. The lower part of both ends of the collector tube fixing bracket 7 is provided with a downwardly protruding mating structure, which can be a lower positioning pin 72. The lower positioning pin 72 can be a fixing post, and the bottom of the fixing post can be set as a cone. The cone-shaped part of the lower positioning pin 72 can automatically guide and connect with the fixing hole at the top of the upper positioning pin 71. The upper fixing structure at both ends and the lower fitting structure at both ends of the collector tube fixing bracket 7 enable further automatic secondary positioning and docking of the upper and lower layers of collector tube fixing bracket 7. The fixing structure and the fitting structure reduce the positioning difficulty of hoisting the collector tube stacking device onto the collector tube receiving and transporting device 100, reduce the accuracy requirements of the hoisting process, and allow the upper layer collector tube stacking device to automatically and accurately align with the lower layer collector tube stacking device that will continue to be stacked, thereby improving hoisting efficiency.

[0059] In some embodiments, such as Figure 3 , Figure 8 , Figure 9 As shown, the mating structure also includes a limiting step (not shown in the attached figure) to restrict the distance between the two heat collector tube fixing brackets 7 when stacked. Specifically, as... Figure 8 , Figure 9 As shown, when the upper and lower layers of heat collector tubes are stacked, the total height of the mating structure and the fixing structure at both ends of the heat collector tube fixing bracket 7 determines the distance between the upper and lower heat collector tube fixing brackets 7. The height and position of the limiting step on the mating structure can determine the ratio of the conical part on the mating structure to the columnar part of the fixing column on the mating structure. Different heights of the limiting step can be set according to specific needs, thereby adjusting the ratio of the columnar part and the conical part on the mating structure and the distance between the upper and lower heat collector tube fixing brackets 7.

[0060] It should be noted that the aforementioned mating structure can also be set on the upper part of the collector tube fixing bracket 7, and the corresponding fixing structure can also be set on the upper part of the collector tube fixing bracket 7, as long as the fixing structures at both ends of the collector tube fixing bracket 7 can cooperate and position with the mating structures at both ends of the next layer and / or the next layer of collector tube fixing bracket 7. The shapes of the aforementioned upper positioning pin 71 and lower positioning pin 72 can be cylindrical, square prism, or regular polygonal prism. The blind hole and the conical part can be set on one of the upper positioning pin 71 and lower positioning pin 72. As long as the adjacent upper positioning pin 71 and lower positioning pin 72 can guide and cooperate with each other for positioning, the scheme is within the protection scope of this application.

[0061] In some embodiments, such as Figure 1 , Figure 2 , Figures 5 to 7 , Figure 12 As shown, the four sets of main support poles are arranged in parallel. The parallel arrangement of the four sets of main support poles, coupled with the fact that each set is perpendicular to its corresponding load-bearing pier 9, further enhances the rigidity of the entire collector tube receiving and transporting device 100. This ensures that the device, once filled with collector tubes M, can withstand impacts from all directions, maximizing the protection of the collector tubes M from damage during transport and handling.

[0062] In some embodiments, such as Figure 3 , Figure 4As shown, the collector tube fixing bracket 7 is provided with spaced-apart limiting grooves 73 and limiting protrusions 75. The limiting grooves 73 restrict the collector tube M from moving laterally in a direction parallel to the collector tube fixing bracket 7, and the limiting protrusions 75 restrict the collector tube M from moving longitudinally in a direction perpendicular to the collector tube fixing bracket 7. The limiting grooves 73 and limiting protrusions 75 are provided on the upper surfaces of both ends of each collector tube fixing bracket 7 that support the collector tube M. The limiting grooves 73 and limiting protrusions 75 can reduce the weight of the collector tube fixing bracket 7 itself, and facilitate the setting to prevent the collector tube M from moving in both the lateral and longitudinal directions, thereby improving the stability and reliability of the entire collector tube storage and transportation device 100 during hoisting or translation.

[0063] In some embodiments, such as Figure 3 , Figure 4 As shown, the collector tube fixing bracket 7 is provided with lifting holes 74. The lifting holes 74 are located at 1 / 4, 2 / 4 and 3 / 4, or 1 / 4 and 3 / 4, which can ensure the balance and stability when the collector tube layered installation is installed in layers, and facilitate the quick disassembly and installation of the single-layer collector tube fixing bracket 7 later. Of course, multiple lifting holes 74 can be provided, which can be evenly distributed along the width direction of the collector tube fixing bracket 7. When actually lifting the collector tube layered installation, the lifting rope 107 can be passed through the lifting hole 74 as needed, and then the two ends of the lifting rope 107 can be hung on the lifting ring 105, so that the entire collector tube layered installation can be lifted by an external lifting device. With lifting holes 74 evenly distributed along the width of the collector tube fixing bracket 7, the lifting device can directly lift the collector tube layered device with the collector tube M mounted on the paired collector tube fixing brackets 7 using the lifting rope 107 and lifting ring 105, without the need for additional lifting frames. This saves the time of lifting and disassembling the collector tube layered device and improves the lifting efficiency.

[0064] It should be noted that after fixing, the distance between the centroids of the two collector tube fixing brackets 7 is equal to the diameter of the collector tube M to be stored, thus achieving a multi-layer stacking effect; the surface of the collector tube fixing bracket 7 in contact with the collector tube is covered with a layer of flexible rubber material (not shown in the attached figure); the lifting hole 74 is used to fix the lifting rope 107 for the overall lifting and transportation of the collector tube storage and transportation device 100; the collector tube fixing bracket 7, which is composed of two sets of main uprights and the guide structure of the two sets of main uprights, together form the upright fixing assembly to protect each layer of stacked collector tubes. The limiting groove 73 and the limiting protrusion 75 of the collector tube fixing bracket 7 are covered with a layer of flexible rubber material (not shown in the attached figure) at the contact positions with the collector tube M. In this way, during the transportation and transfer of the collector tube storage and transportation device 100, it can prevent minor impacts from causing collisions between the collector tube M and the collector tube storage and transportation device 100, as well as between the collector tube M and the collector tube M, which would lead to damage to the collector tube M.

[0065] In some embodiments, such as Figure 1 , Figure 2 , Figures 5 to 7 , Figure 12 As shown, the collector tube storage and transportation device 100 also includes a protective frame (2, 5) detachably connected to the main support pole assembly. The protective frame (2, 5) can improve the rigidity of the entire collector tube storage and transportation device 100 and enhance its impact resistance in both directions perpendicular to the axis of the collector tube M, ensuring that the collector tube M is not damaged during transportation and transfer.

[0066] In some embodiments, such as Figure 1 , Figure 2 , Figures 5 to 9 , Figure 12 As shown, the protective frame (2, 5) includes multiple connecting plates (21, 51) detachably connected to the main upright assembly and at the same horizontal height, horizontal connecting rods (23, 53) detachably connected to the connecting plates, and vertical connecting rods (22, 52) detachably connected to the connecting plates. The horizontal connecting rods (23, 53) and the vertical connecting rods (22, 52) are detachably connected to the connecting plates (21, 51) by fastening screws (24, 54). The connecting plates (21, 51) have notches (211, 511) on one side facing the outside of the heat collection tube receiving and transporting device 100 for attaching the hanging rope 107. The horizontal connecting rods (23, 53) and the vertical connecting rods (22, 52) are connected end to end in sequence through the connecting plates (21, 51) to form a rectangular protective frame that can resist impacts in multiple directions. The connecting plate is detachably connected to the main upright assembly, providing a fulcrum and force point for the installation of the protective frame. It also facilitates the adjustment of the installation height of the connecting plate on the main upright assembly. The horizontal and vertical connecting rods are connected end to end in sequence through the connecting plate, which facilitates the formation of a whole protective frame. The horizontal and vertical connecting rods connected end to end form a mutually abutting structure at the joint, which can further improve the rigidity of the entire protective frame and enhance the impact resistance of the entire heat collection tube storage and transportation device.

[0067] In some embodiments, such as Figure 1 , Figure 2 , Figures 5 to 9 , Figure 12 As shown, the solar collector tube storage and transportation device 100 includes multiple protective frames (2, 5) arranged at different heights. Depending on the needs, protective frames at different heights can be installed on the four main support pole groups. The spacing density of the protective frames in the height direction depends on the location of any lateral impacts that the entire solar collector tube storage and transportation device 100 may experience during transportation and transfer. Furthermore, as... Figure 1 , Figure 2 , Figures 5 to 7As shown, protective frames are installed at the top and bottom of the entire heat collector tube storage and transportation device 100, which can at least protect against the impact of objects with a height greater than the height of the main support assembly on the direction perpendicular to the axis of the heat collector tube M.

[0068] In some embodiments, such as Figure 1 , Figure 2 , Figures 5 to 7 , Figure 12 As shown, the heat collector tube storage and transportation device 100 also includes multiple sets of diagonal bracing assemblies (3, 4). Each set of diagonal bracing assemblies (3, 4) is cross-connected to the upper and lower parts of two adjacent sets of main uprights. Each set of diagonal bracing assemblies (3, 4) is equipped with an adjustable tension adjustment mechanism. Specifically, as shown... Figure 1 , Figure 2 , Figures 5 to 7 , Figure 12 As shown, the diagonal bracing assembly includes short diagonal bracing assemblies 3, which are vertically intersecting between two groups of closely spaced main uprights, and long diagonal bracing assemblies 4, which are vertically intersecting between two groups of widely spaced main uprights. The short diagonal bracing assemblies 3 and 4 are connected end-to-end around the four groups of main uprights in a crisscross pattern, further increasing the rigidity of the entire collector tube receiving and transporting device 100 and enhancing its ability to withstand impacts from external forces on all four sides. If necessary, adjustable tensioning mechanisms can be cross-located between adjacent groups of main uprights to further improve the rigidity of the entire collector tube receiving and transporting device 100 and prevent deformation during hoisting.

[0069] In some embodiments, such as Figure 1 , Figure 2 , Figures 5 to 7 , Figure 12 As shown, the diagonal bracing assembly (3, 4) includes a diagonal tie rod (not shown in the attached figure) connected at one end to the main upright assembly and a lead screw (not shown in the attached figure) connected at one end to the main upright assembly and rotatably connected to the diagonal tie rod at the other end. The diagonal tie rod and the lead screw rotatably connected to the diagonal tie rod can rotate relative to each other to adjust the length of the diagonal bracing assembly (3, 4), thereby further adjusting the magnitude of the tension on the diagonal bracing assembly (3, 4) between the main upright assemblies. The greater the tension on the diagonal bracing assembly (3, 4), the better the rigidity of the entire heat collection tube receiving and transporting device 100, and the stronger its ability to resist external impacts from the four sides.

[0070] In some embodiments, such as Figure 1 , Figure 2 , Figures 5 to 7 , Figure 12As shown, the pallet has forklift holes on all four sides (not shown in the attached diagram). Although the bottom of the aforementioned load-bearing block 9 is raised a certain distance above the pallet frame 8, allowing forklifts and other transport tools to directly insert the entire collector tube storage and transport device 100 from the bottom of the pallet frame 8, the addition of forklift holes to the pallet frame 8 further restricts the space for the forklift's forks to move, ensuring the stability of the center of gravity when the forklift moves. This prevents damage to the collector tube M caused by the impact of the entire collector tube storage and transport device 100 sliding on the forklift's forks during forklift transport.

[0071] In some embodiments, a separate lifting assembly can be used when hoisting the heat collector tube storage and transportation device 100. This assembly includes a lifting frame 10, which comprises two end beams 103. Multiple downwardly extending lifting beams 104 are provided on the end beams 103 at both ends of the lifting frame 100. The ends of the lifting beams 104 are provided with lifting locking holes 1041 corresponding to the lifting holes 74 of the heat collector tube fixing bracket 7. Lifting pins 106 can be inserted into both ends of the end beams 103 to detachably connect the heat collector tube storage and transportation device 100. The lifting device is detachably connected to the lifting frame 10 to allow for replacement with lifting frames of different specifications. Furthermore, the lifting frame 10 also includes multiple longitudinal beams 101 assembled longitudinally and transversely into a whole and fixedly connected to the end beams 103, as well as multiple transverse beams 102 fixedly connected between the multiple longitudinal beams 101. The end beams 103 are fixedly connected to both ends of the multiple longitudinal beams 101. Furthermore, the hoisting assembly also includes a clamping bracket 20 that can clamp two sets of collector tube fixing brackets that are snapped together and filled with collector tubes M from both ends of the hoisting frame 10. The clamping frame 20 includes a main beam 201 parallel to the end beam 103, a vertical beam 202 extending upward from the upper surface of the main beam, and a clamping beam 203 extending horizontally from the vertical beam toward the collector tube fixing bracket. The main beam 201 is provided with a plurality of clamping pins 204 corresponding to the lifting clamping holes 1041 on the side facing the collector tube fixing bracket 7. The vertical beam 202 is provided with through holes (not shown in the figure) corresponding to the lifting clamping holes on both sides facing and away from the collector tube fixing bracket 7. The clamping beam 203 abuts against the upper surface of the middle longitudinal beam 101 of the hoisting frame 10 during the hoisting of the collector tube receiving and transporting device 100 by the hoisting assembly. The plurality of clamping pins 204 can pass through the through holes, the lifting clamping holes 1041 and the lifting holes 74 in sequence, and can jointly bear the weight of the entire collector tube layering device. Furthermore, the end of the locking pin 204 is provided with a slot for elastically engaging the retaining spring. The retaining spring prevents the entire heat collector tube layer assembly from slipping off the locking pin 204 due to impact during hoisting. After hoisting into place, the retaining spring, which is secured to the slot to ensure hoisting safety, can be removed before hoisting the next layer of heat collector tube layer assembly.

[0072] It should be noted that the hoisting assembly also includes hoisting pins 106 for connecting the four main uprights. Specifically, as shown... Figure 12 As shown, after the last layer of collector tubes is hoisted into the collector tube receiving and transporting device 100, if it is necessary to continue hoisting the entire collector tube receiving and transporting device 100, which is filled with collector tubes M, onto a vehicle or other location, the two ends of the end beam 103 of the hoisting frame 10 and the four sets of main uprights can be pinned together using the hoisting pins 106. After the pinning is completed, the hoisting device can lift the hoisting frame 10 and transfer the lifting force to the entire collector tube receiving and transporting device 100 through the hoisting pins 106, thereby enabling subsequent hoisting work. This eliminates the trouble of using a forklift to lift the entire collector tube receiving and transporting device 100 or continuing to pass the hoisting ropes through the hoisting holes 91 on the four load-bearing piers 9, improving hoisting efficiency and increasing the utilization rate of the hoisting frame 10.

[0073] It should be noted that the pallet, main support pole assembly, main support pole connecting cover, protective frame, heat collector tube layering device, and hoisting components of the heat collector tube storage and transportation device 100 can all be modularly disassembled and stored after transportation, which can reduce transportation space.

[0074] The aforementioned collector tube storage and transportation device 100 can be hoisted as a whole or in layers, facilitating both transportation and rapid installation, thus improving transportation reliability and hoisting efficiency. Furthermore, its detachable structure allows for disassembly after transportation, reducing the overall transport volume, saving space, and lowering transportation costs.

[0075] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
