Description

Technical Field

[0001] This application relates to the field of flood control and disaster relief material storage and transportation technology, and in particular to a transportation and storage device that can adapt to flood control materials of various lengths and specifications, specifically a multi-functional adjustable flood control material transportation and storage device. Background Technology

[0002] Flood control and disaster relief geotextile is a geosynthetic material specifically designed for emergency flood control projects. It is a permeable fabric-like material made from high molecular polymers such as polyester (PET) or polypropylene (PP) through melting, spinning, web laying, and needle punching reinforcement.

[0003] Each roll of long-filament geotextile for flood control and disaster relief is approximately 4 meters long, with a circular diameter of about 0.43 meters and a weight of about 120 kg. Traditional storage involves placing the geotextile rolls on pallets, with steel columns used for lateral support to prevent slippage. Because storage regulations stipulate that geotextile stacking height cannot exceed 1.7 meters, the utilization rate of storage space is low, increasing storage management costs.

[0004] Secondly, stacking cylindrical geotextile rolls for storage can easily cause them to slide sideways, posing a safety hazard.

[0005] Secondly, when cylindrical geotextile rolls are stacked high, the lack of ventilation in the middle of the rolls makes them prone to mold growth, which in turn affects the quality of flood control materials. To prevent mold growth, the traditional solution is to turn the rolls over more than twice a year for ventilation and drying, but this results in a significant waste of manpower, material resources, and financial resources.

[0006] Therefore, traditional storage methods cannot meet the safety standards and quality control requirements of modern flood control material reserve management.

[0007] In addition, each roll of geotextile weighs 120 kg and is 4 meters long. Transporting and loading it requires four people to lift each roll, which is labor-intensive and inefficient. Even using forklifts in conjunction with manual lifting, the transport speed is very slow, and the fabric is prone to bending, deformation, and localized damage. Based on the current loading methods, loading a 13-meter-long truck takes at least 1.5 hours, which cannot meet the requirement of delivering supplies to the front lines of flood control and disaster relief as quickly as possible.

[0008] Therefore, it is urgent to propose a new technical solution to address the problems existing in the current technology. Summary of the Invention

[0009] This application provides a multifunctional adjustable flood control material transportation and storage device, which can adapt to the storage and transportation of flood control materials of various lengths and specifications.

[0039] Compared with the prior art, this application has at least the following beneficial effects:

[0040] 1. Based on further analysis and research of existing technologies, this application recognizes that current geotextile rolls are prone to lateral slippage when stacked high and have low transportation efficiency, making it difficult to meet the timeliness requirements of flood control and disaster relief. Therefore, this application provides a multi-functional adjustable flood control material transportation and storage device. Two support seats are arranged on the left and right sides of the upper surface of the base, with an intermediate support seat between them. This creates a forkhole between the three support seats, allowing forklift forks to pass through, facilitating forklift loading and unloading of flood control materials. Furthermore, the application includes forkholes inside the base, allowing forklift forks to easily move the transportation and storage device. Moreover, the application features side barriers and adjustable frames around the device, which not only enclose the flood control materials, completely avoiding the risk of lateral slippage, but also allow for adjustment of the storage state by raising and lowering the adjustable frames. For example, when the adjustable frames are lowered, woven bags and containers can be placed inside. The device can accommodate fixed-length flood control materials such as bags, and after the adjustable frame is lowered, it can also accommodate flood control materials of varying lengths such as geotextiles and timber, effectively realizing the multi-functionality and versatility of the transport and storage device. Furthermore, this application includes a stacking protrusion on the top of the transport and storage device and a stacking groove at the bottom. Two transport and storage devices can be reliably stacked by fitting together the stacking protrusion and the stacking groove. Therefore, the transport and storage device provided by this application can reliably store flood control materials of various lengths in a surrounding manner, preventing lateral slippage when stacked, improving storage safety, and the adjustable frame's retraction and extension enhance the device's multi-functionality and versatility. It also allows for rapid transport of materials within the device and the entire device through the upper and lower fork holes, saving labor and increasing efficiency. Moreover, the stacking groove and stacking protrusion enable multi-layer stable stacking, saving storage space.

[0041] 2. The left and right bearing seats of the transport and storage device provided in this application are respectively equipped with side guards at the front and rear ends. The four side guards can form a side enclosure for flood control materials, improving the storage and installation performance. In addition, the middle of the two left side guards and the middle of the two right side guards are respectively equipped with connecting rings and rope tensioners for installing ropes. The ropes can restrict, constrain and prevent the flood control materials in the storage space from shifting, improving the stability of the materials during the movement.

[0042] 3. The top of the transport and storage device provided in this application is provided with two top rails. The top rails are connected to the connecting pins on the top of the transport and storage device by means of the perforated fasteners at both ends. This connection is detachable. When the adjustment racks on the left and right sides are lowered, the device is used to store materials with a long length. If the materials need to be hoisted into the device, the top rails can be removed. After the materials are stacked, the top rails can be installed. The top rails can prevent the top width of the transport and storage device from being deformed by force. Of course, even if the adjustment racks on the left and right sides are retracted, if the materials need to be hoisted into the device, the top rails can be removed and then reinstalled in the same way.

[0043] 4. The left and right adjustment frames of the transport and storage device provided in this application are hinged to the edges of the left and right bearing seats via hinges. The adjustment frames are equipped with perforated ear plates, which are adapted to the hole seats on the side rails. When the adjustment frame is rotated relative to the bearing seat to the vertical enclosed state (i.e., the retracted state), the perforated ear plates on the front and rear sides of the adjustment frame and the hole seats on the lower part of the side rails are aligned and connected through the bent end of the tie rod. The other end of the tie rod is connected to the hole seat on the upper part of the side rails. At this time, the adjustment frame is fixed to the side rails by the tie rod, making the overall structure stable and forming an enclosed storage space. When the adjustment frame is rotated relative to the bearing seat to the horizontal bearing state (i.e., the lowered state), the perforated ear plates on the front and rear sides of the adjustment frame are connected to one end of the tie rod, and the other end of the tie rod is connected to the hole seat on the lower part of the side rails. At this time, the tie rod can ensure that the adjustment frames on both sides are opened stably and do not sag, providing a longer bearing surface for flood control materials.

[0044] 5. In this application, ventilation holes are evenly distributed on the plates of the left, middle and right bearing seats to achieve ventilation inside the device and prevent materials from becoming moldy; at the same time, the device is a steel frame structure, which not only meets the structural requirements, but also reduces the self-weight of the unit and allows for ventilation.

[0045] 6. Tensioners are installed at both the front and rear ends of the left side of the left bearing seat and at both the front and rear ends of the right side of the right bearing seat. Correspondingly, iron rings are installed at both the front and rear ends of the left side of the top of the device and at both the front and rear ends of the right side of the top of the device. Basically, the four iron rings at the top and the four tensioners at the bottom correspond one-to-one. In use, the two tensioners at the bottom left and the two iron rings at the top left are connected by a rope, and the two tensioners at the bottom right and the two iron rings at the top right are connected by a rope. This design, which connects the top iron rings through two sets of tensioners on each side of the bottom of the bearing seat, can ensure the safety and stability of the entire device. In addition, the four iron rings at the top can not only be used to thread ropes to stabilize the device, but also serve as lifting points for hoisting and transferring the stacked device.

[0046] 7. The base of this application is a frame structure. The frame structure can not only meet the structural support requirements, but also reduce the unit's self-weight, allow for ventilation, and form fork holes in its own structure that are compatible with forklift forks.

[0047] 8. The stacking protrusion in this application is a triangular prism with its length direction parallel to the base, and the cross-section of the stacking protrusion is an isosceles triangle. The stacking groove is adapted to mate with the stacking protrusion. Therefore, the stacking groove is a strip groove in the shape of a triangular prism. This concave-convex mating form can reliably position and mate. Moreover, the cross-section of the stacking protrusion is set as an isosceles triangle. Under the action of gravity, the triangle automatically mates and closes vertically and stably, ensuring the reliability of the connection and vertical stability of the upper and lower stacks.

[0068] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0069] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0070] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0071] This application provides a multifunctional adjustable flood control material transportation and storage device, which enables mechanized and rapid storage, transportation, loading, and unloading of flood control materials within the device and the entire device, improving the utilization rate of storage space and flood control emergency response capabilities. The transportation and storage device provided in this application can be directly used in flood control and disaster relief material storage and transportation work. The adjustable frames on both sides of the device can be retracted or extended. When lowered, it can be used to store flood control materials of varying lengths, such as geotextiles and timber; when retracted, it can store flood control materials of fixed sizes, such as woven bags and container bags. Through the adjustable structural design on both sides, the device effectively achieves multifunctionality and versatility.

[0072] See Figure 1 and Figure 5 This application provides a multifunctional adjustable flood control material transportation and storage device, including a base 1 and a left support seat 2, a middle support seat 8, and a right support seat 9 arranged sequentially at intervals on the upper surface of the base 1. Side blocks are respectively provided at the front and rear ends of the left support seat 2. The left side of the left support seat 2 is connected to a left adjustment frame 6 via a hinge. The left adjustment frame 6 is detachably connected to the two side blocks located at the front and rear ends of the left support seat 2. The left adjustment frame 6 can be rotated relative to the left support seat 2 to a vertically enclosed state (e.g., ...). Figure 1 ) or horizontal load-bearing condition (e.g. Figure 5 ).

[0073] Similarly, side blocks are provided at the front and rear ends of the right bearing seat 9, and the right side of the right bearing seat 9 is connected to the right adjustment frame 13 by a hinge. The right adjustment frame 13 is detachably connected to the two side blocks provided at the front and rear ends of the right bearing seat 9. The right adjustment frame 13 can be rotated relative to the right bearing seat 9 to a vertical enclosed state or a horizontal bearing state by a hinge.

[0074] Based on this, the left-side support 2, the left-side adjusting frame 6, the two side blocks located at the front and rear ends of the left-side support 2, the middle support 8, the right-side support 9, the right-side adjusting frame 13, and the two side blocks located at the front and rear ends of the right-side support 9 together form a storage space for placing flood control materials. The four side blocks can provide side protection for flood control materials to prevent them from slipping, and the two adjusting frames can be extended and retracted, allowing the device to adapt to materials of different lengths and specifications, thus improving the versatility and multi-functionality of the device.

[0075] In this application, the upper surfaces of the left adjusting frame 6, the right adjusting frame 13, the left bearing seat 2, the right bearing seat 9, and the middle bearing seat 8 are all located on the same horizontal plane. The gaps between the left bearing seat 2 and the middle bearing seat 8, and between the right bearing seat 9 and the middle bearing seat 8, respectively form fork holes that allow forklift forks to pass through, denoted as the first fork hole 26. Therefore, forklifts can be used to place flood control materials into the device or to remove flood control materials from the device, saving labor and increasing efficiency.

[0076] This application also provides a fork hole in the base 1 that allows forklift forks to pass through, referred to as the second fork hole 27, to facilitate the transfer and transportation of the entire device using a forklift.

[0077] This application also provides multiple stacking grooves on the lower surface of the base 1. Stacking protrusions are respectively provided on the tops of the two side rails located at the front and rear ends of the left bearing seat 2 and the two side rails located at the front and rear ends of the right bearing seat 9. The stacking grooves and stacking protrusions correspond one-to-one. One transport and storage device connects with the stacking protrusion on the top of another transport and storage device through the stacking groove at its bottom to achieve vertical stacking of the two transport and storage devices. A schematic diagram of the vertical stacking of multiple transport and storage devices can be found in [reference needed]. Figure 7 .

[0078] Therefore, the transport and storage device provided in this application can reliably store flood control materials of various lengths and specifications in an enclosed manner, avoiding side slippage when stacked, improving storage safety, and the retraction and extension of the adjustment frame can enhance the multifunctionality and versatility of the device; it can also realize the rapid transport of materials and the entire device through the upper and lower fork holes, which is labor-saving and efficient; it can also achieve multi-layer stable stacking through stacking grooves and stacking protrusions, saving storage space.

[0079] In a preferred embodiment, see Figure 1 The two side blocks located at the front and rear ends of the left bearing seat 2 are the first side block 3 and the second side block 4, respectively. Preferably, the first side block 3 and the second side block 4 have the same structure.

[0080] Taking the first side bar 3 as an example, the first side bar 3 includes: two vertical bars arranged parallel to each other on the left and right, multiple horizontal bars connected between the two vertical bars, and an extended horizontal bar connected to the top of the two vertical bars. The right half of the extended horizontal bar is connected to the two vertical bars, the left half of the extended horizontal bar is cantilevered, the upper surface of the right half of the extended horizontal bar is provided with a stacking protrusion, and the upper surface of the left half of the extended horizontal bar is provided with an iron ring 16 and multiple connecting pins 17.

[0081] A first connecting ring 303 is provided on the middle crossbar of the first side barrier 3, and a first rope tensioner 403 is provided on the middle crossbar of the second side barrier 4. The flood control materials stored in the storage space are restrained by a rope with one end connected to the first rope tensioner 403 and the other end tied to the first connecting ring 303.

[0082] A first top fence 5 spans between the extended crossbar at the top of the first side barrier 3 and the extended crossbar at the top of the second side barrier 4. The front and rear ends of the first top fence 5 each form a perforated fastening seat. The first top fence 5 is detachably connected to the connecting pin 17 at the top of the first side barrier 3 and the second side barrier 4 via the fastening seats. The first top fence 5 prevents deformation of the top width of the transport storage device due to stress.

[0083] In a preferred embodiment, the specific connection structure between the left adjustment bracket 6 and the two left side blocks is as follows:

[0084] See Figure 3 and Figure 5 The left vertical rod of the first side stop 3 has a first hole seat 301 and a second hole seat 302 on its side wall, with the first hole seat 301 directly above the second hole seat 302. The left vertical rod of the second side stop 4 has a third hole seat 401 and a fourth hole seat 402 on its side wall, with the third hole seat 401 directly above the fourth hole seat 402. The front and rear ends of the left adjustment frame 6 are respectively provided with a first perforated ear plate 601 and a second perforated ear plate 602.

[0085] When the left adjustment frame 6 rotates to a vertically closed state relative to the left support seat 2 via the hinge, the first perforated ear plate 601 and the second hole seat 302 are aligned front to back and connected to the first bent end of the first pull rod 7. The second perforated ear plate 602 and the fourth hole seat 402 are aligned front to back and connected to the first bent end of the second pull rod 14. The second bent end of the first pull rod 7 is connected to the first hole seat 301, and the second bent end of the second pull rod 14 is connected to the third hole seat 401.

[0086] When the left adjustment frame 6 rotates to a horizontal bearing state relative to the left bearing seat 2 via the hinge, the first bent end of the first pull rod 7 is connected to the first perforated ear plate 601, the second bent end of the first pull rod 7 is connected to the second hole seat 302, the first bent end of the second pull rod 14 is connected to the second perforated ear plate 602, and the second bent end of the second pull rod 14 is connected to the fourth hole seat 402.

[0087] This method of structural connection using a detachable tie rod to assist in adjusting the frame in different states is convenient to use, simple to operate, highly reliable, and has low processing, manufacturing, and maintenance costs.

[0088] In a preferred embodiment, see Figure 1 The two side blocks located at the front and rear ends of the right side bearing seat 9 are the third side block 10 and the fourth side block 11, respectively. Preferably, the third side block 10 and the fourth side block 11 have the same structure, and the structure of the third side block 10 and the fourth side block 11 is preferably the same as that of the first side block 3 or the second side block 4.

[0089] Taking the third side bar 10 as an example, the third side bar 10 includes: two vertical bars arranged parallel to each other on the left and right, multiple horizontal bars connected between the two vertical bars, and an extended horizontal bar connected to the top of the two vertical bars. The left half of the extended horizontal bar is connected to the two vertical bars, and the right half of the extended horizontal bar is cantilevered. The upper surface of the left half of the extended horizontal bar is provided with a stacking protrusion, and the upper surface of the right half of the extended horizontal bar is provided with an iron ring 16 and multiple connecting pins 17.

[0090] A second rope tensioner 1001 is installed on the middle crossbar of the third side barrier 10, and a second connecting ring 1101 is installed on the middle crossbar of the fourth side barrier 11. The flood control materials stored in the storage space are restrained by a rope with one end connected to the second rope tensioner 1001 and the other end tied to the second connecting ring 1101.

[0091] A second top fence 12 is connected between the extended crossbar at the top of the third side barrier 10 and the extended crossbar at the top of the fourth side barrier 11. The front and rear ends of the second top fence 12 form perforated fastening seats. The second top fence 12 is detachably connected to the connecting pins 17 at the top of the third and fourth side barriers 10 and 11 via these fastening seats. The second top fence 12 prevents deformation of the top width of the transport storage device due to stress.

[0092] In a preferred embodiment, the specific connection structure between the right-side adjusting bracket 13 and the two right-side side blocks is as follows:

[0093] The right vertical rod of the third side stop 10 has a first hole seat 301 and a second hole seat 302 on its side wall, with the first hole seat 301 directly above the second hole seat 302. The right vertical rod of the fourth side stop 11 has a third hole seat 401 and a fourth hole seat 402 on its side wall, with the third hole seat 401 directly above the fourth hole seat 402. The front and rear ends of the right adjustment frame 13 are respectively provided with a first perforated ear plate 601 and a second perforated ear plate 602.

[0094] When the right adjustment frame 13 rotates to a vertically enclosed state relative to the right bearing seat 9 via the hinge, the first perforated ear plate 601 and the second hole seat 302 are aligned front to back and connected to the first bent end of the third pull rod. The second perforated ear plate 602 and the fourth hole seat 402 are aligned front to back and connected to the first bent end of the fourth pull rod. The second bent end of the third pull rod is connected to the first hole seat 301, and the second bent end of the fourth pull rod is connected to the third hole seat 401.

[0095] When the right adjustment frame 13 rotates to a horizontal bearing state relative to the right bearing seat 9 via the hinge, the first bent end of the third tie rod is connected to the first perforated ear plate 601, the second bent end of the third tie rod is connected to the second hole seat 302, the first bent end of the fourth tie rod is connected to the second perforated ear plate 602, and the second bent end of the fourth tie rod is connected to the fourth hole seat 402.

[0096] In one specific embodiment, see Figure 5 The aforementioned first top fence 5 and second top fence 12 have the same structure. See also Figure 4 Taking the second top fence 12 as an example, the second top fence 12 includes: two horizontal beams arranged parallel to each other at intervals, and a plurality of horizontal short posts arranged sequentially at intervals between the two horizontal beams. Each horizontal beam has a snap-fit ​​seat 1201 with holes at both ends. A total of eight snap-fit ​​seats with holes are formed on the two top fences, which can be detachably inserted into the connecting pins 17 provided on the top of the four side rails. The top fence can prevent the transport and storage device from deforming under force in the width direction. Preferably, the snap-fit ​​seats at the ends of the top fences are L-shaped plates.

[0097] Therefore, the left and right support seats 2 and 9 of the transport and storage device provided in this application are respectively equipped with side barriers at their front and rear ends. The four side barriers can form a side enclosure for flood control materials, improving the storage and installation performance. In addition, the middle of the two left side barriers and the middle of the two right side barriers are respectively equipped with connecting rings and rope tensioners for installing ropes. The ropes can restrict, constrain, and prevent the flood control materials in the storage space from shifting, improving the stability of the materials during movement. For example, it can prevent geotextile rolls from affecting the safety of storage and transportation due to elastic shaking and deformation within the device.

[0098] In addition, two top rails are installed on the top of the four side rails. The top rails are connected to the connecting pins 17 located on the top of the transport and storage device through the perforated fasteners at both ends. This connection is detachable. When the adjustment frames on the left and right sides are lowered, the device is used to store materials with a longer length. If the materials need to be hoisted into the device, the top rails can be removed. After the materials are stacked, the top rails can be installed. The top rails can prevent the top width of the transport and storage device from being deformed by force and prevent changes in the width of the device from affecting the stability of the upper and lower layers.

[0099] Furthermore, the left and right adjustment frames of the transport and storage device provided in this application are hinged to the edges of the left and right support seats via hinges, and the adjustment frames are provided with perforated ear plates, which are adapted to the perforated seats on the side blocks through the perforated ear plates. When the adjustment frame is rotated relative to the support seat to the vertical closed state (i.e., the retracted state, such as...), Figure 1 The perforated lugs on the front and rear sides of the adjustment frame are aligned with the lower hole seats on the side rails and connected by the bent end of the tie rod. The other end of the tie rod is connected to the upper hole seat on the side rails. At this point, the adjustment frame is fixed to the side rails by the tie rod, making the overall structure stable and forming an enclosed storage space. When the adjustment frame is rotated relative to the bearing seat to the horizontal bearing state (i.e., the lowered state, such as...), Figure 5 , 6 The perforated lugs on the front and rear sides of the adjustment frame are connected to one end of the tie rod, and the other end of the tie rod is connected to the hole seat on the lower side of the side block. At this time, the tie rod can ensure that the adjustment frame on both sides is stable and does not sag when opened, providing a longer bearing surface for flood control materials.

[0100] In a preferred embodiment, the left support 2 in this application includes a left frame structure extending outward from the base 1 and a right support plate connected above the base 1. Specifically, the right half of the left support 2 connected above the base 1 is a support plate with evenly distributed ventilation holes on its surface, and the left half of the left support 2 extending outward from the base 1 is a frame structure formed by welding square tubes. Preferably, the structure of the right support 9 is symmetrical to that of the left support 2. The extended structural design of the left and right support seats can increase the storage space of the device and improve the load-bearing area of ​​the support seats. In addition, ventilation holes are evenly distributed on the three support seats to achieve ventilation inside the device and prevent materials from becoming moldy.

[0101] In a preferred embodiment, the left adjustment frame 6 and the right adjustment frame 13 of this application are structurally symmetrical. The left adjustment frame 6 is hinged to the left outer edge of the left support seat 2 via a hinge, and the right adjustment frame 13 is hinged to the right outer edge of the right support seat 9 via a hinge, as shown below. Figure 5 .

[0102] Taking the left-side adjusting frame 6 as an example, the left-side adjusting frame 6 includes: two opposing uprights, one end of which is connected to a hinge, and the other end of which is connected to a horizontal crossbar. Connecting columns are respectively installed at both ends of the horizontal crossbar, perpendicular to both the uprights and the horizontal crossbar. Perforated lugs are installed at the ends of the two connecting columns. When the adjusting frame is folded up into a vertical position, the two uprights and the horizontal crossbar act as a barrier. When the adjusting frame is lowered into a horizontal load-bearing state, the two uprights and the horizontal crossbar provide bottom support, and the two connecting columns can be connected to tie rods via perforated lugs at their ends, ensuring the structural stability of the adjusting frame and preventing sagging.

[0103] In a preferred embodiment, see Figure 1 The left half of the left bearing seat 2 is provided with a third rope tensioner 18 and a fourth rope tensioner 19 at its front and rear ends, respectively. The transport and storage device is constrained by a rope that is connected to the third rope tensioner 18 at one end and passes through the top iron ring 16 of the first side guard 3 and the top iron ring 16 of the second side guard 4 in sequence before being connected to the fourth rope tensioner 19.

[0104] Similarly, see Figure 1 The right half of the right-side bearing seat 9 is equipped with a fifth rope tensioner 20 and a sixth rope tensioner 21 at its front and rear ends, respectively. The transport and storage device is constrained by a rope that is connected at one end to the fifth rope tensioner 20 and at the other end that passes through the top iron ring 16 of the third side guard 10 and the top iron ring 16 of the fourth side guard 11 and then connects to the sixth rope tensioner 21.

[0105] The design of connecting the top iron rings 16 with two groups of tightrope devices on both sides of the bottom of the bearing seat can lock the stacked overall materials and ensure the safety and stability of the entire device. In addition, the four iron rings 16 on the top can not only be threaded with ropes to stabilize the device, but also be used as lifting points to lift and transfer the stacked device.

[0106] In a preferred embodiment, the base 1 in the present application is of a frame structure. Refer to Figure 2 , the base 1 includes a horizontally arranged crossbeam in the shape of a rectangle with a hole in the middle, and a horizontally arranged crossbeam in the shape of a rectangle with a hole in the middle fixed below the horizontally arranged crossbeam in the shape of a rectangle with a hole in the middle by multiple vertical beams. A fork hole is formed between the horizontally arranged crossbeam in the shape of a rectangle with a hole in the middle and the horizontally arranged crossbeam in the shape of a rectangle with a hole in the middle, allowing the forklift fork to pass through.

[0107] In a preferred embodiment, refer to Figure 1 , a first stacking protrusion 22 is provided at the top of the first side baffle 3, a second stacking protrusion 23 is provided at the top of the second side baffle 4, a third stacking protrusion 24 is provided at the top of the third side baffle 10, and a fourth stacking protrusion 25 is provided at the top of the fourth side baffle 11. At the same time, a first stacking groove corresponding to the first stacking protrusion 22 up and down, a second stacking groove corresponding to the second stacking protrusion 23 up and down, a third stacking groove corresponding to the third stacking protrusion 24 up and down, and a fourth stacking groove corresponding to the fourth stacking protrusion 25 up and down are provided on the lower surface of the horizontally arranged crossbeam in the shape of a rectangle with a hole in the middle of the base 1. When two lifting and storage devices are stacked up and down, the upper lifting and storage device is inserted and matched with the four stacking protrusions at the top of the lower lifting and storage device through the four stacking grooves at its bottom, ensuring the reliability and stability of the connection.

[0108] In a preferred embodiment, the above-mentioned stacking protrusion is a triangular prism with a length direction parallel to the base 1, and the cross-section of the stacking protrusion is an isosceles triangle. The stacking groove is docked with the stacking protrusion in a matching manner. Therefore, the stacking groove is a strip-shaped groove in the shape of a triangular prism. This concave-convex matching form can achieve reliable positioning and docking. Moreover, the cross-section of the stacking protrusion is set as an isosceles triangle, and under the action of gravity, the triangle automatically docks and closes vertically and stably, ensuring the connection reliability and vertical stability of the upper and lower stacking.

[0109] On this basis, a 45° bevel cut can be provided on one side of the stacking protrusion in the shape of a triangular prism. Naturally, 45° bevel cuts are also provided at both ends of the stacking groove for matching installation. The setting of this 45° bevel cut is more convenient for upper and lower alignment installation than the groove with vertical planes at both ends, and has a certain installation guiding effect, which can reduce the difficulty of alignment installation during upper and lower alignment installation.

[0110] In other embodiments, the above-mentioned stacking protrusion can also be a cuboid with a length direction parallel to the base 1, and the cross-section of the stacking protrusion is a square or a rectangle. Or, continuous saw teeth can be provided on the upper surface of the cuboid stacking protrusion.

[0111] In a preferred embodiment, the base 1, left adjustment frame 6, first side guard 3, second side guard 4, right adjustment frame 13, third side guard 10, fourth side guard 11, first top fence 5, and second top fence 12 in this application are all frame structures formed by welding square tubes. For ease of processing, the front and rear crossbars of the U-shaped horizontal beam at the bottom of the base 1 are made of equilateral angle steel with a 90° apex angle. The equilateral angle steel naturally forms isosceles triangular prism-shaped strip grooves that match the shape of the stacked protrusions.

[0112] In one specific embodiment, the position of the stacking protrusion on top of the first side guard 3 preferably corresponds vertically to the position of the crossbar in the middle of the first side guard 3, and the lengths are the same. The structural arrangement of the stacking protrusions on top of the other three side guards is preferably the same. This structural design allows the equilateral angle steel at the bottom of the base 1, together with the steel pipes at both ends of the equilateral angle steel, to form a stacking groove that matches the stacking protrusion. The steel pipes at both ends of the equilateral angle steel abut against the two ends of the stacking protrusion, preventing lateral movement and ensuring the vertical safety and anti-slip of the upper and lower layer transfer and storage device.

[0113] The transportation and storage device provided in this application can be used for reliable multi-layer stacking. Compared with traditional warehousing methods, it can increase the reserve of geotextile rolls by at least 2 times and realize unitized transportation. This unitized transportation method can improve the speed and efficiency of flood control and disaster relief transportation by more than 5 times and save more than 80% of the annual management costs for stacking and anti-slipping.

[0114] In a specific application example, the transfer and storage device can be manufactured by welding 5*5 cm square tubes of Q235B steel with a wall thickness of 0.20 cm and a column wall thickness of 0.25 cm.

[0115] In one specific embodiment, the external dimensions of the transport and storage device are as follows: After the adjustment frame is retracted, the device stores fixed-size materials such as woven bags, measuring 2.2 meters in length, 1.30 meters in width, and 2.05 meters in height. Each device stores 24 bundles of frosted thickened woven bags, arranged in 4 layers high (6 layers in total), with 500 bags per bundle, totaling 12,000 woven bags. After the adjustment frames on both sides are opened, the device measures a total of 3.368 meters in length, 1.3 meters in width, and 2.05 meters in height. Each device stores 8 rolls of geotextile, arranged in 2 layers high (4 layers in total), with 400 square meters per roll, totaling 3,200 square meters of geotextile.

[0116] Of course, this application provides a technical concept for a multifunctional adjustable flood control material transportation and storage device. Based on this, in practical applications, transportation and storage devices of other sizes can be customized according to the size and stacking height requirements of the target stored materials.

[0117] In summary, this application provides a multifunctional adjustable flood control material transportation and storage device, capable of storing various types and specifications of flood control materials, which are reusable and save management costs. Furthermore, the transportation and storage device provided by this application has a simple overall structure and is designed with multiple sets of safety and stability measures. Using this device can promote the standardization of flood control material reserves and effectively improve flood control emergency response capabilities.

[0118] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0119] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
