[0002] As environmental protection issues are receiving more and more attention from the world, the development and utilization of new energy has become a future trend.

Trough solar thermal power generation can maintain the stability of power generation day and night, and is one of the mainstream directions of future new energy development.

[0003] Trough solar thermal power generation utilizes parabolic trough reflectors to generate solar thermal power. This system utilizes numerous parabolic trough concentrating collectors arranged in series and parallel to collect high-temperature heat, which is then used to heat a working medium to generate steam that drives a turbine generator set for power generation. However, the parabolic trough concentrating collectors utilize glass tubes, which are fragile and cannot be stacked and transported in large quantities.

[0064] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0065] like Figures 1-14 As shown, the present invention provides an embodiment of a heat collecting tube storage and transportation device.

[0066] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 As shown, the heat collecting tube storage and transportation device 100 includes four main pole groups (not marked in the drawings) and a heat collecting tube layering device (not marked in the drawings) vertically arranged on a pallet tray (not marked in the drawings); the pallet tray includes a pallet frame 8 and load-bearing piers 9 fixedly connected to the four corners of the bottom of the pallet frame 8, and the load-bearing piers 9 are provided with lifting holes 91. The pallet frame 8 of the heat collecting tube storage and transportation device 100 can be directly forked and transported by a forklift, or the heat collecting tube storage and transportation device 100 can be directly lifted as a whole through the lifting holes on the load-bearing piers 9; the main pole group is a group of two adjacent main poles 6, and the four main pole groups are respectively It is detachably connected to the four load-bearing piers 9, and a guide structure (not marked in the accompanying drawings) is provided on the main pole group; the heat collecting tube layer loading device includes at least two heat collecting tube fixing brackets 7 and heat collecting tubes M for storing heat collecting tubes, and both ends of the heat collecting tube fixing bracket 7 can be restricted in the guide structure to restrict the rolling and horizontal movement of the heat collecting tubes; the two upper and lower adjacent heat collecting tube fixing brackets 7 can be pinned and aligned with each other, and multiple heat collecting tube fixing brackets 7 are stacked in sequence, and the heat collecting tube layer loading device can be directly hoisted onto the heat collecting tube storage and transportation device 100, and each layer of heat collecting tube layer loading device can be slid up and down in the guide structure, aligned and pinned.

[0067] The beneficial effects of the present invention are as follows: the heat collecting tube storage and transportation device disclosed in the present invention includes four groups of main pole groups and heat collecting tube layer loading devices vertically arranged on the pallet tray, which can realize the overall lifting of the entire heat collecting tube storage and transportation device, and can also realize the layered lifting of each layer of heat collecting tube layer loading device to the heat collecting tube storage and transportation device, and can also be forked and transported by a forklift; the heat collecting tube layer loading device includes at least two heat collecting tube fixing brackets and heat collecting tubes for storing heat collecting tubes, and the two ends of the heat collecting tube fixing bracket can be restricted in the guide structure, and the two upper and lower adjacent heat collecting tube fixing brackets can be pinned and aligned with each other, and multiple heat collecting tube fixing brackets are stacked in sequence, which is convenient for each layer of heat collecting tube layer loading device to be quickly docked, stacked and installed on the heat collecting tube storage and transportation device, and it is also convenient for multiple heat collecting tube storage and transportation devices to be neatly and stably placed on the transportation tool to realize batch transportation, which can improve the reliability of transportation and the lifting efficiency. At the same time, the heat collecting tube storage and transportation device adopts a detachable structure, which can be disassembled after the transportation is completed, reducing the overall transportation volume, saving transportation space and reducing transportation costs.

[0068] In this embodiment, specifically, Figure 1 、 Figure 2 、 Figure 3 As shown, the pallet tray includes a pallet frame 8 connected into a whole by multiple crisscrossing pallet beams (not marked in the drawings) and load-bearing piers 9 fixedly connected to the four corners of the bottom of the pallet frame 8. The bottom surface of the load-bearing piers 9 protrudes from the bottom surface of the pallet frame 8. On the one hand, the load-bearing piers 9 can bear the weight of the entire heat collecting tube storage and transportation device and the weight of all the heat collecting tubes stored therein, so that the load-bearing piers 9 can concentrate on bearing the impact and wear of the bottom during transportation and transit. On the other hand, the bottom of the load-bearing piers 9 is just raised a certain distance above the pallet frame 8, which is convenient for forklifts and other transport tools to directly insert the entire heat collecting tube storage and transportation device 100 from the bottom of the pallet frame 8, thereby making it easier for special tools such as forklifts to directly fork the entire heat collecting tube storage and transportation device 100. It should be noted that multiple crisscrossing pallet beams are connected to form an integral pallet frame 8, and the load-bearing piers 9 are fixedly connected to the four corners of the bottom of the pallet frame 8. The connection of multiple pallet beams and the connection of the load-bearing piers 9 with the pallet frame 8 can be achieved by direct welding, fastening connection through fasteners such as screws and bolts, clipping, and snapping. As long as the technical solutions can achieve stable and reliable connection of multiple pallet beams and stable and reliable connection of the load-bearing piers 9 with the pallet frame 8, they are within the scope of protection of this application and will not be described here one by one.

[0069] In this embodiment, specifically, Figure 1 、 Figure 2 、 Figure 3As shown, the main rod group is a group of two adjacent main rods 6, and the four main rod groups are respectively perpendicular to the upper surface 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 rods 6 in each main rod group. The width of the gap is equivalent to the thickness of the heat collecting tube fixing bracket 7 in the axial direction of the heat collecting tube mounted on it, that is, the heat collecting tube fixing bracket 7 can move up and down and forward and backward in the gap. The gap extends from the bottom where the two adjacent main rods 6 are connected to the load-bearing pier 9 to the top of the two adjacent main rods 6 to form a guide structure that can limit the moving direction of the heat collecting tube fixing bracket 7, which can ensure that after the heat collecting tube layer installation is stacked, there is no large moving space between the main rods. Furthermore, the main rod 6 can be cylindrical, square, or regular polygonal. As long as a gap can be left between two adjacent main rods 6 to form a guide structure that allows the heat collecting tube fixing bracket 7 to move freely up and down and forward and backward, it is within the scope of protection of this application. On the one hand, the main pole group composed of two main poles 6 with a gap between them improves the vertical rigidity of the entire heat collecting tube storage and transportation device, and the ability of the main pole group to resist vertical and horizontal impacts is at least doubled compared to a single main pole 6. On the other hand, the guide structure between the two main poles 6 of the main pole group further limits the direction in which the heat collecting tube fixing bracket 7 can move freely up and down and forward and backward, which facilitates the hoisting of the heat collecting tube layer installation device formed by the paired heat collecting tube fixing brackets 7 after the heat collecting tubes are erected onto the heat collecting tube storage and transportation device 100, thereby improving the convenience of hoisting.

[0070] In this embodiment, specifically, Figure 3 、 Figures 5 to 9 As shown, the entire heat collecting tube storage and transportation device 100 can accommodate multiple layers of heat collecting tube layer packaging devices in the vertical direction, and the two upper and lower adjacent heat collecting tube fixing brackets 7 can be pinned and aligned with each other, and multiple heat collecting tube fixing brackets can be stacked in sequence. Figure 8 、 Figure 9 As shown, between the lowest layer and the second lowest layer of heat collecting tube layer installations, between the topmost layer and the second highest layer of heat collecting tube layer installations, and between two layers of heat collecting tube layer installations stacked in sequence, each heat collecting tube fixing bracket 7 is provided with a fixing part (not marked in the drawings) for stacking and fixing the heat collecting tube fixing bracket plates, and the fixing part includes a fixing structure (not marked in the drawings) on the upper end face and a matching structure (not marked in the drawings) on the lower end for matching with the fixing structure on the upper end face; each heat collecting tube fixing bracket 7 is provided with a fixing structure and a matching structure so that the heat collecting tube fixing bracket 7 of the upper layer and / or the next layer of heat collecting tube layer installation corresponding to the heat collecting tube fixing bracket 7 can be conveniently aligned and engaged with each other, thereby improving the efficiency of stacking multiple heat collecting tube layer installations in sequence.

[0071] In some embodiments, as Figure 1 、 Figure 6 、 Figure 7 、 Figure 9 As shown, the heat collecting tube storage and transportation device 100 further includes a main rod connecting cover plate 1, which is connected to the top of two adjacent main rod groups to prevent the heat collecting tube fixing bracket 7 from sliding out from the top of the guide structure. Figure 7 、 Figure 9 As shown, the main rod connecting cover plate 1 connects the tops of the four main rods 6 of the two adjacent main rod groups, which can further prevent the four main rods 6 from being displaced and twisted with each other under the action of external force, and also further prevent the top-layer heat collecting tube fixing bracket 7 of the heat collecting tube layer installation device that has already installed the heat collecting tubes from sliding upward out of the guide structure under the action of external force. Simply put, the main rod connecting cover plate 1 can limit the heat collecting tube fixing bracket 7 from jumping upward, so that when the entire heat collecting tube storage and transportation device 100 is subjected to external force impacts in various directions during transportation and transit, the heat collecting tubes M contained in the heat collecting tube storage and transportation device 100 will not collide with each other.

[0072] In some embodiments, as Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 As shown, the heat collecting tube fixing bracket 7 is provided with a fixing part (not shown in the drawing) for stacking and fixing the heat collecting tube fixing bracket 7. The fixing part includes an upper end provided with a fixing structure and a lower end provided with a matching structure for matching with the fixing structure. The matching structures at the lower ends of the upper heat collecting tube fixing bracket 7 can be used to automatically position and dock the fixing structures at the upper ends of the lower heat collecting tube fixing bracket 7, thereby reducing the difficulty of alignment when hoisting the heat collecting tube layer installation device onto the heat collecting tube storage and transportation device 100, reducing the precision requirements of the hoisting process, and allowing the hoisted upper heat collecting tube layer installation device to automatically and accurately align with the lower heat collecting tube layer installation device to be stacked, thereby improving the hoisting efficiency.

[0073] In some embodiments, as Figure 1 、 Figure 2 、 Figures 5 to 9 As shown, the guide structure includes a guide groove (not shown in the drawings) provided between the two main rods 6 of each main rod group, and both ends of the heat collecting tube fixing bracket 7 can slide in the guide groove. Figure 8 、 Figure 9As shown, a gap is left between two adjacent main poles 6 in each main pole group, and the width of the gap is equivalent to the thickness of the heat collecting tube fixing bracket 7 in the axial direction of the heat collecting tube mounted on it, that is, the heat collecting tube fixing bracket 7 can move up and down and forward and backward in the gap. The gap extends from the bottom where the two adjacent main poles 6 are connected to the load-bearing pier 9 to the top of the two adjacent main poles 6 to form a guide groove that can limit the moving direction of the heat collecting tube fixing bracket 7. The guide groove helps the two upper and lower adjacent heat collecting tube fixing brackets 7 to be pinned and aligned with each other, so that when hoisting the heat collecting tube layer mounting device, there is no need to deliberately align the heat collecting tube fixing brackets 7 of the upper and lower layers of the hoisting heat collecting tube layer mounting device. First, the guiding effect of the guide groove is used to determine the preliminary hoisting position of the upper heat collecting tube fixing bracket 7, and then the fixing structure at the upper two ends of the lower heat collecting tube fixing bracket 7 (not marked in the drawing) is used to achieve further automatic secondary positioning and docking. The guide structure reduces the difficulty of aligning the heat collecting tube layer installation device to the heat collecting tube storage and transportation device 100 when hoisting it, reduces the accuracy requirements of the hoisting process, and allows the hoisted upper heat collecting tube layer installation device to automatically and accurately align with the lower heat collecting tube layer installation device to be stacked, thereby improving the hoisting efficiency.

[0074] In some embodiments, as Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 As shown, the fixing structure includes a fixing hole (not shown in the drawings), and the matching structure includes a fixing column (not shown in the drawings) that can be received in the fixing hole, and the end of the fixing column is set to be conical. Figure 3 As shown, the upper parts of both ends of the heat collecting tube fixing bracket 7 are 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 pass through the end of the heat collecting tube fixing bracket 7; the lower parts of both ends of the heat collecting tube fixing bracket 7 are provided with a downwardly protruding matching structure, which can be a lower positioning pin 72. The lower positioning pin 72 can be a fixing column, and the bottom of the fixing column can be set to a cone. The conical part of the lower positioning pin 72 can realize automatic guided docking with the fixing hole at the top of the upper positioning pin 71. The fixing structures at the upper ends of the heat collecting tube fixing bracket 7 and the matching structures at the lower ends realize further automatic secondary positioning and docking of the upper and lower heat collecting tube fixing brackets 7. The fixing structures and the matching structures reduce the difficulty of alignment when hoisting the heat collecting tube layer mounting device to the heat collecting tube storage and transportation device 100, and reduce the accuracy requirements of the hoisting process. The hoisted upper heat collecting tube layer mounting device can automatically and accurately align with the lower heat collecting tube layer mounting device to be stacked, thereby improving the hoisting efficiency.

[0075] In some embodiments, as Figure 3 、 Figure 8 、 Figure 9 As shown, the matching structure is also provided with a limiting step (not shown in the drawing) for limiting the distance between the two heat collecting tube fixing brackets 7 when stacking. Figure 8 、 Figure 9 As shown, when the upper and lower layers of heat collecting tube layer installations are stacked, the total height of the matching structures and the fixing structures at both ends of the heat collecting tube fixing bracket 7 determines the distance between the upper and lower heat collecting tube fixing brackets 7. The height position of the limiting step on the matching structure can determine the ratio of the conical part on the matching structure and the columnar part of the matching structure fixing column. Different heights of the limiting steps are set according to specific needs, thereby adjusting different ratios of the columnar part and the conical part on the matching structure and different distances between the upper and lower heat collecting tube fixing brackets 7.

[0076] It should be noted that the aforementioned matching structure can also be provided on the upper portion of the heat collecting tube fixing bracket 7, and the corresponding aforementioned fixing structure can also be provided on the upper portion of the heat collecting tube fixing bracket 7, as long as the fixing structures at both ends of the heat collecting tube fixing bracket 7 can cooperate with the matching structures at both ends of the next layer and / or the next layer of heat collecting tube fixing bracket 7 for positioning. The aforementioned upper positioning pin 71 and lower positioning pin 72 can be shaped like a cylinder, a square column, or a regular polygonal column, and the aforementioned blind hole and tapered portion can be provided on either the upper positioning pin 71 or the lower positioning pin 72. As long as the adjacent upper positioning pins 71 and lower positioning pins 72 can guide each other for cooperation and positioning, all such solutions fall within the scope of protection of this application.

[0077] In some embodiments, as Figure 1 、 Figure 2 、 Figures 5 to 7 、 Figure 12 As shown, the four main rod groups are arranged in parallel. The four main rod groups are arranged in parallel, and each main rod group is perpendicular to the corresponding load-bearing pier 9, which can further improve the rigidity of the entire heat collecting tube storage and transportation device 100. After being fully loaded with heat collecting tubes M, the entire heat collecting tube storage and transportation device 100 can withstand external forces from all directions, thereby protecting the heat collecting tubes M from damage during transportation and turnover to the greatest extent.

[0078] In some embodiments, as Figure 3 、 Figure 4As shown, the heat collecting tube fixing bracket 7 is provided with spaced apart limiting grooves 73 and limiting protrusions 75. The limiting grooves 73 limit the lateral movement of the heat collecting tube M in a direction parallel to the heat collecting tube fixing bracket 7, and the limiting protrusions 75 limit the longitudinal movement of the heat collecting tube M in a direction perpendicular to the heat collecting tube fixing bracket 7. The limiting grooves 73 and limiting protrusions 75 are provided on the upper surfaces of both ends of each heat collecting tube fixing bracket 7 on which the heat collecting tube M is mounted. The limiting grooves 73 and limiting protrusions 75 not only reduce the weight of the heat collecting tube fixing bracket 7 itself, but also facilitate the arrangement to prevent the heat collecting tube M from moving in both the lateral and longitudinal directions, thereby improving the stability and reliability of the entire heat collecting tube storage and transportation device 100 during hoisting or translation.

[0079] In some embodiments, as Figure 3 、 Figure 4 As shown, the heat collecting tube fixing bracket 7 is provided with hanging holes 74, which are arranged at 1 / 4, 2 / 4 and 3 / 4, or at 1 / 4 and 3 / 4, to ensure balance and stability when the heat collecting tube layered assembly is hoisted in layers, and facilitate the subsequent quick disassembly and hoisting of the single-layer heat collecting tube fixing bracket 7. Of course, multiple hanging holes 74 can be provided, and they can be evenly distributed along the width direction of the heat collecting tube fixing bracket 7. When actually hoisting the heat collecting tube layered assembly, the hanging rope 107 can be passed through the hanging holes 74 as needed, and then the two ends of the hanging rope 107 are hung on the hanging rings 105, and the entire heat collecting tube layered assembly can be hoisted using an external lifting device. The lifting holes 74 are evenly distributed along the width direction of the heat collecting tube fixing bracket 7, so that the lifting device can use the lifting rope 107 and the lifting ring 105 to directly lift the heat collecting tube layer installation device with the heat collecting tubes M installed on the paired heat collecting tube fixing brackets 7 without the need for additional lifting frames, which can save the time of lifting and disassembling the heat collecting tube layer installation device and improve the lifting efficiency.

[0080] It should be noted that after fixation, the distance between the centers of mass of the two heat collecting tube fixing brackets 7 is equal to the diameter of the heat collecting tube M to be stored, thereby achieving a multi-layer stacking effect; the surface of the heat collecting tube fixing bracket 7 in contact with the heat collecting tube is wrapped with a layer of flexible rubber material (not marked in the drawings); the lifting hole 74 is used to fix the lifting rope 107 for the overall lifting and transportation of the heat collecting tube storage and transportation device 100; the heat collecting tube fixing bracket 7 composed of two groups of main pole groups with a relatively close distance and the guide structures of the two groups of main pole groups together constitutes a force rod fixing assembly for protecting each layer of stacked heat collecting tubes, and the limiting groove 73 and the limiting protrusion 75 of the heat collecting tube fixing bracket 7 in contact with the heat collecting tube M are wrapped with a layer of flexible rubber material (not marked in the drawings), so that during the transportation of the heat collecting tube storage and transportation device 100, it can prevent small impacts from causing collisions between the heat collecting tube M and the heat collecting tube storage and transportation device 100, as well as between the heat collecting tube M and the heat collecting tube M, thereby preventing damage to the heat collecting tube M.

[0081] In some embodiments, as Figure 1 、 Figure 2 、 Figures 5 to 7 、 Figure 12 As shown, the heat collecting tube storage and transportation device 100 further includes a protective frame (2, 5) detachably connected to the main rod group. The protective frame (2, 5) can improve the rigidity of the entire heat collecting tube storage and transportation device 100, and can improve the impact resistance of the entire heat collecting tube storage and transportation device 100 in directions perpendicular to the axis direction of the heat collecting tube M, thereby ensuring that the heat collecting tube M is not damaged during transportation and transit.

[0082] In some embodiments, as Figure 1 、 Figure 2 、 Figures 5 to 9 、 Figure 12 As shown, the protective frame (2, 5) includes a plurality of connecting plates (21, 51) detachably connected to the main rod group and at the same horizontal height, transverse connecting rods (23, 53) detachably connected to the connecting plates, and longitudinal connecting rods (22, 52) detachably connected to the connecting plates, the transverse connecting rods (23, 53) and the longitudinal connecting rods (22, 52) being detachably connected to the connecting plates (21, 51) by fastening screws (24, 54); a notch (211, 511) for clamping the suspension rope 107 is provided on one side of the connecting plate (21, 51) facing the outside of the heat collecting tube storage and transportation device 100; the transverse connecting rods (23, 53) and the longitudinal connecting rods (22, 52) are sequentially connected end to end at intervals through the connecting plates (21, 51) to form a rectangular protective frame capable of resisting impacts in multiple directions. The connecting plate is detachably connected to the main pole group, providing a fulcrum and fulcrum for the installation of the protective frame, and also facilitating the adjustment of the installation height of the connecting plate on the main pole group. The transverse connecting rods and the longitudinal connecting rods are sequentially connected end to end through the connecting plate, so as to form an overall protective frame. The transverse connecting rods and the longitudinal connecting rods connected end to end form a mutually abutting structure at the joint, which can further enhance the rigidity of the entire protective frame and enhance the impact resistance of the entire heat collecting tube storage and transportation device 100.

[0083] In some embodiments, as Figure 1 、 Figure 2 、 Figures 5 to 9 、 Figure 12 As shown, the heat collecting tube storage and transportation device 100 includes a plurality of protection frames (2, 5) arranged at different heights. As needed, the protection frames at different heights can be installed on the four main pole groups. The spacing density of the protection frames in the height direction depends on the position where the entire heat collecting tube storage and transportation device 100 may be subjected to side impacts during transportation and transfer. Further, as shown in FIG. Figure 1 、 Figure 2 、 Figures 5 to 7As shown, protective frames are set at the top and bottom areas of the entire heat collecting tube storage and transportation device 100, which can at least protect the heat collecting tube M from impacts from objects whose height is greater than the height of the main pole group in the direction perpendicular to the axis.

[0084] In some embodiments, as Figure 1 、 Figure 2 、 Figures 5 to 7 、 Figure 12 As shown, the heat collecting tube storage and transportation device 100 further comprises a plurality of diagonal bracing assemblies (3, 4), each of which cross-connects the upper and lower parts of two adjacent main rod groups, and each of which is provided with an adjustable tension mechanism. Specifically, Figure 1 、 Figure 2 、 Figures 5 to 7 、 Figure 12 As shown, the diagonal brace assembly includes a short diagonal brace assembly 3 that is intersected vertically between two closely spaced main pole groups, and a long diagonal brace assembly 4 that is intersected vertically between two farther-spaced main pole groups. The short diagonal brace assembly 3 and the long diagonal brace assembly 4 are intersected end-to-end around the four main pole groups, further increasing the rigidity of the entire heat collecting tube storage and transportation device 100 and enhancing its ability to withstand external impacts from all four sides. As needed, an adjustable tension adjustment mechanism intersecting between two adjacent main pole groups can improve the rigidity of the entire heat collecting tube storage and transportation device 100 and prevent deformation during the hoisting process.

[0085] In some embodiments, 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 accompanying drawings) having one end connected to the main rod group and a screw rod (not shown in the accompanying drawings) having one end connected to the main rod group and the other end rotatably connected to the diagonal tie rod. The diagonal tie rod and the screw rod rotatably connected to the diagonal tie rod can be rotated relative to each other to adjust the length of the diagonal bracing assembly (3, 4), thereby further adjusting the magnitude of the tension borne on the diagonal bracing assembly (3, 4) between the main rod groups. The greater the tension borne on the diagonal bracing assembly (3, 4), the better the rigidity of the entire heat collecting tube storage and transportation device 100, and the stronger the ability to resist external impacts from four sides.

[0086] In some embodiments, as Figure 1 、 Figure 2 、 Figures 5 to 7 、 Figure 12As shown, forklift holes are provided on all four sides of the pallet (not shown in the accompanying drawings). Although the bottom of the aforementioned load-bearing pier 9 is elevated a certain distance above the pallet frame 8, allowing a forklift or other transport tool to directly insert the entire heat collecting tube storage and transportation device 100 from the bottom of the pallet frame 8, the pallet frame 8 with the forklift holes further limits the space in which the forklift's fork arm can move when inserted into the pallet frame 8, ensuring a stable center of gravity when the forklift is moving, thereby preventing the entire heat collecting tube storage and transportation device 100 from being impacted by external forces during the forklift transport process and the impact force generated by the sliding of the forklift's fork arm, which could damage the heat collecting tubes M.

[0087] In some embodiments, a separate hoisting assembly can be used when hoisting the heat collecting tube storage and transportation device 100. The hoisting assembly includes a hoisting frame 10, and the hoisting frame 10 includes two end beams 103. The end beams 103 at both ends of the hoisting frame 10 are provided with a plurality of hoisting beams 104 extending downward. The ends of the hoisting beams 104 are provided with hoisting holes 1041 corresponding to the hoisting holes 74 of the heat collecting tube fixing bracket 7. Hoisting pins 106 can also be inserted into the ends of the end beams 103 to detachably connect the heat collecting tube storage and transportation device 100. The lifting device is detachably connected to the hoisting frame 10 to replace hoisting frames of different specifications. Furthermore, the hoisting frame 10 also includes a plurality of longitudinal beams 101 assembled vertically and horizontally into a whole and fixedly connected to the end beams 103, and a plurality of transverse beams 102 fixedly connected between the plurality of longitudinal beams 101. The end beams 103 are fixedly connected to both ends of the plurality of longitudinal beams 101. Furthermore, the hoisting assembly also includes a clamping frame 20 that can clamp two groups of heat collecting tube fixing brackets that are clamped and filled with heat collecting tubes M from both ends of the hoisting frame 10. The clamping frame 20 includes a main beam 201 arranged 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 one side of the heat collecting 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 heat collecting tube fixing bracket 7; the vertical beam 202 is provided with through holes corresponding to the lifting clamping holes on both sides facing and away from the heat collecting tube fixing bracket 7 (not marked in the drawings); the clamping beam 203 abuts against the upper surface of the middle longitudinal beam 101 of the lifting frame 10 during the process of lifting the heat collecting tube storage and transportation device 100 with the lifting 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 heat collecting tube layer installation device. Furthermore, a slot for elastically engaging a retaining spring is provided at the end of the retaining pin 204. The retaining spring prevents the entire heat collecting tube layer assembly from sliding off the retaining pin 204 due to impact during the hoisting process. After the assembly is hoisted into place, the retaining spring, which is engaged in the slot to ensure safe hoisting, can be removed, and then the next layer of heat collecting tube assembly can be hoisted.

[0088] It should be noted that the hoisting assembly also includes a hoisting pin 106 for pinning the four main rod groups. Figure 12 As shown, after the last layer of heat collecting tube layer loading device is hoisted onto the heat collecting tube storage and transportation device 100, if it is necessary to continue to hoist the entire heat collecting tube storage and transportation device 100 filled with heat collecting tubes M onto a vehicle or other place, the two ends of the end beam 103 of the hoisting frame 10 and the four groups of main rods can be pinned together with the hoisting pins 106. After the pinning is completed, the hoisting device can lift the hoisting frame 10 to transmit the lifting force to the entire heat collecting tube storage and transportation device 100 through the hoisting pins 106, so as to carry out subsequent hoisting work. This saves the trouble of using a forklift to pick up the entire heat collecting tube storage and transportation device 100 or continuing to use the hoisting rope to re-pass through the hoisting holes 91 on the four load-bearing piers 9, thereby improving the efficiency of hoisting and improving the utilization rate of the hoisting frame 10.

[0089] It should be noted that the pallet tray, main pole group, main pole connecting cover, protective frame, heat collecting tube layer installation device, and lifting assembly of the heat collecting tube storage and transportation device 100 can be modularly disassembled and can be disassembled and stored after transportation is completed, which can reduce the transportation space.

[0090] Since the heat collecting tube storage and transportation device 100 can be hoisted as a whole or in layers, it is convenient for transportation and can be quickly installed, thereby improving transportation reliability and hoisting efficiency. At the same time, the detachable structure allows for disassembly after transportation, reducing the overall transportation volume, saving transportation space, and reducing transportation costs.

[0091] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
