Description

Technical Field

[0001] This invention belongs to the field of transportation equipment technology, and in particular relates to a material bag for waterway transportation. Background Technology

[0002] Oil tankers often weigh hundreds of thousands of tons, with huge hulls and high construction costs. Due to their deep draft, they are difficult to operate on inland waterways because of the numerous bridges, shoals, and narrow channels.

[0003] Para-aramid is a type of aramid fiber, characterized by high strength, high modulus, light weight, and outstanding heat resistance. Its strength is 5-6 times that of steel, its modulus is 2-3 times that of steel or glass fiber, and its toughness is twice that of steel, while its weight is only 1 / 5 that of steel. It retains its original strength even after being exposed to 200°C for hundreds of hours and does not decompose or melt at 560°C. Furthermore, para-aramid also possesses good impact resistance, corrosion resistance, and fatigue resistance. Due to these advantages, para-aramid is known as "bulletproof fiber" and is widely used in aerospace, defense, personal protective equipment, and sports and leisure industries.

[0004] Therefore, using para-aramid vulcanized fabric to make material bags for transporting oil is an ideal choice, which can greatly save the manufacturing cost of transportation equipment and transportation costs. When collecting oil, the transport bags can be folded and placed on small cargo ships. After the oil is filled, the small cargo ships can tow the bags or the material bags can be propelled by their own power, which greatly increases the flexibility of inland waterway liquid transportation. However, material bags still face the aforementioned problems in inland waterway transportation.

[0005] How to solve the problem of inland waterway transportation of material bags is a technical issue that urgently needs to be addressed. Summary of the Invention

[0006] The purpose of this invention is to provide a material bag for waterway transportation in order to solve the above-mentioned technical problems.

[0007] The technical solution adopted in this invention is as follows:

[0008] A material bag for waterway transportation includes a transport bag body made of para-aramid vulcanized fabric, a first sealed bearing fixed at the front and rear ends of the transport bag body, a deformable rotating shaft connected in a chain shape by universal joints, and multiple bag deformation mechanisms disposed within the transport bag body. The universal joint at the rear end of the deformable rotating shaft is in sealed rotational engagement with the first sealed bearing at the rear end of the bag body, and the universal joint at the front end of the deformable rotating shaft is in sealed rotational engagement with the first sealed bearing at the front end of the bag body. The bag deformation mechanism includes a fixed structure located on the universal joint and multiple pull ropes fixedly connected to and wound around the fixed structure. Each pull rope is wound around the fixed mechanism in a set direction, and the other end of each pull rope is fixed circumferentially to the inner wall of the transport bag body.

[0009] Preferably, the fixing structure is a columnar body of a universal joint, with four pull ropes fixed and wound around the corresponding columnar body. Two of the ropes are distributed horizontally along the radial direction and wound clockwise around the corresponding columnar body, while the other two are distributed vertically along the radial direction and wound counterclockwise around the corresponding columnar body.

[0010] Preferably, the fixing structure includes an electromagnet with communication and remote control function fixed to the columnar body of the universal joint, a fixing ring with a first snap-fit ​​unit fixed to one side of the electromagnet, a sliding sleeve slidably sleeved on the corresponding columnar body, and a stop ring provided on the rear side of the sliding sleeve. The end face of the sliding sleeve facing the first snap-fit ​​unit has a second snap-fit ​​unit that snaps into and cooperates with the first snap-fit ​​unit. The pull rope is correspondingly fixed and wound around the outer circumferential surface of the sliding sleeve.

[0011] Preferably, at least one annular airbag is provided inside the transport bag. The inner ring of the annular airbag is fixed on the outer ring of a slip ring or a second bearing. The slip ring or the second bearing is in a sealed rotational fit with the columnar body of the corresponding universal joint. The first air pipe that passes through the transport bag is connected to the corresponding annular airbag through a first solenoid valve.

[0012] Preferably, the outer side of the transport bag is provided with a protective bag made of flexible waterproof material.

[0013] Preferably, the protective bag body is sealed and fixed together with the transport bag body at the filling port and the first sealing bearing, and the second air pipe that passes through the transport bag body is connected to the inside of the protective bag body. The second air pipe is equipped with a second solenoid valve.

[0014] Preferably, multiple connecting ropes are provided between the transport bag and the protective bag.

[0015] Preferably, the bottom of the transport bag has a counterweight.

[0016] Preferably, the outer surface of the transport bag has a pressure sensor, a liquid level sensor, and / or a temperature sensor.

[0017] Preferably, monitoring cameras are installed at the bottom, sides and / or top of the protective bag.

[0018] The material bag for waterway transportation of the present invention adopts a deformable rotating shaft connected in a chain shape by universal joints and a bag deformation mechanism. In use, the deformable rotating shaft is rotated by a drive mechanism outside the material bag. Since each pull rope is wound around the fixed mechanism in a set direction, during the rotation of the deformable rotating shaft, the corresponding pull rope is driven to pull or release in different directions inside the transport bag, so that the transport bag can be deformed to facilitate passage through waterways with various conditions.

[0019] Furthermore, the fixed structure is a universal joint-shaped column, with four pull ropes fixed and wound around it. Two of these ropes are radially horizontally distributed and wound clockwise around the corresponding column, while the other two are radially vertically distributed and wound counterclockwise around the corresponding column. When the deformable shaft rotates clockwise, the radially horizontally distributed pull ropes are gradually released, while the vertically distributed pull ropes are gradually pulled, causing the transport bag to gradually flatten on the water surface, reducing its draft and height, making it easier to pass through shallow water areas or the arches of low bridges. When the deformable shaft rotates counterclockwise, with some air filling the transport bag, it gradually becomes taller vertically and narrower horizontally, facilitating passage through narrow waterways, making it extremely flexible to use.

[0020] Furthermore, the fixing structure includes an electromagnet with communication and remote control function fixed to the columnar body of the universal joint, a fixing ring with a first locking unit fixed to one side of the electromagnet, a sliding sleeve slidably sleeved on the corresponding columnar body, and a stop ring located on the rear side of the sliding sleeve. The end face of the sliding sleeve facing the first locking unit has a second locking unit that engages with the first locking unit. The pull rope is fixed and wound around the outer circumference of the sliding sleeve. In use, as needed, while rotating the deformable shaft, the corresponding electromagnet is energized to attract the corresponding sliding sleeve, locking the first locking unit and the second locking unit together, thereby pulling or releasing the pull rope corresponding to the sliding sleeve. This allows different parts of the transport bag to be deformed as needed, making it more flexible. For example, in areas with rapid changes from shallow to narrow water, if the transport bag is raised as a whole, it is easy to get stranded; if it is flat as a whole, it cannot pass through. In such cases, the bag can be deformed in sections to allow passage through each section.

[0021] Furthermore, at least one annular airbag is installed inside the transport bag. In extreme cases, if the transport bag is damaged, the annular airbag will be inflated to divide the transport bag into multiple chambers, minimizing the loss. The inner ring is fixed to the outer ring of the slip ring or the second bearing. The slip ring or the second bearing is sealed and rotated with the columnar body of the corresponding universal joint to avoid interference with the rotation of the deformable shaft.

[0022] Furthermore, a protective bag made of flexible waterproof material is installed on the outside of the transport bag to provide secondary protection against water, impact from obstacles, and leakage.

[0023] Furthermore, the protective bag is sealed and fixed together with the transport bag at the filling port and the first sealing bearing. The second air pipe, which passes through the transport bag, is connected to the inside of the protective bag. The second air pipe has a second solenoid valve. Inflating the air can increase buoyancy and increase the passage capacity in shallow water.

[0024] Furthermore, multiple connecting ropes are provided between the transport bag and the protective bag. When inflated, they can form a relatively stable airbag frame, facilitating the loading and unloading of materials from the transport bag.

[0025] Furthermore, the bottom of the transport bag has a counterweight. When the transport bag and / or protective bag are filled with a certain amount of gas, the counterweight ensures that the transport bag remains upright and prevents it from tipping over to one side when it increases in height due to deformation.

[0026] Furthermore, the outer surface of the transport bag is equipped with a pressure sensor, a liquid level sensor, and / or a temperature sensor, which can monitor whether the transport bag is leaking liquid and the temperature, providing data for subsequent intervention.

[0027] Furthermore, monitoring cameras are installed at the bottom, sides, and / or top of the protective bag to further monitor the bag and enable intervention measures to be taken. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0032] Example 1

[0033] A type of material bag used for waterway transportation, such as Figure 1 and Figure 2As shown, the system includes a transport bag body 1 made of para-aramid vulcanized fabric, a protective bag body 2 located on the outside of the transport bag body, and first sealed bearings 12 and 14 fixed at the front and rear ends of the transport bag body. In this embodiment, the transport bag body is vulcanized fabric made of 1414 aramid fabric. The transport bag body is connected by universal joints 15 to form a chain-like deformable rotating shaft 19 and multiple bag deformation mechanisms located inside the transport bag body. The universal joint at the rear end of the deformable rotating shaft is sealed and rotated with the first sealed bearing 14 at the rear end of the bag body, and the universal joint at the front end of the deformable rotating shaft is sealed and rotated with the first sealed bearing 12 at the front end of the bag body. The bag deformation mechanism includes a fixed structure located on the universal joint and multiple pull ropes 10 and 11 fixedly connected to and wound around the fixed structure. Each pull rope is wound around the fixed mechanism in a set direction, and the other end of each pull rope is fixed circumferentially to the inner wall of the transport bag body.

[0034] In this embodiment, the fixing structure includes an electromagnet 16 with communication and remote control function fixed to the columnar body 20 of the universal joint, a fixing ring 5 with a first snap-fit ​​unit fixed to one side of the electromagnet, a sliding sleeve 18 slidably sleeved on the corresponding columnar body, and a stop ring 17 provided on the rear side of the sliding sleeve. The end face of the sliding sleeve facing the first snap-fit ​​unit has a second snap-fit ​​unit that snaps into the first snap-fit ​​unit. In this embodiment, both the first snap-fit ​​unit and the second snap-fit ​​unit are snap-fit ​​teeth. In other embodiments, they can also be corresponding insertion holes and insertion rods. The pull ropes 10 and 11 are fixed and wound around the outer circumference of the sliding sleeve. The remote-controlled electromagnet is existing technology and will not be described in detail here.

[0035] At least one annular airbag 9 is provided inside the transport bag. The inner ring of the annular airbag is fixed on the outer ring of the slip ring or the second bearing. The slip ring or the second bearing is sealed and rotated with the columnar body of the corresponding universal joint. In this embodiment, three annular airbags are provided. The second bearing 13 is used to seal the first air pipe 6 that passes through the transport bag. They are respectively connected to the corresponding annular airbags through the first solenoid valve (not shown in the figure). The first solenoid valve can be remotely controlled and is an existing product.

[0036] The protective bag can be made of waterproof fabric, polyethylene, or impregnated nylon, with impregnated nylon being preferred due to its strong elasticity and heat insulation properties, providing waterproofing, impact resistance, and leak prevention. The protective bag is sealed and fixed to the transport bag at the filling port 4 and the first sealing bearing, using either melt-pressing or bonding methods. A second air pipe 7, passing through the transport bag, connects to the interior of the protective bag. This second air pipe has a second solenoid valve (not shown in the figure), which is remotely controllable and is an existing product. Multiple connecting ropes 3 connect the transport bag and the protective bag. The bottom of the transport bag has a counterweight 8, and the outer surface of the transport bag has a pressure sensor, a liquid level sensor, and / or a temperature sensor (not shown in the figure). Monitoring cameras (not shown in the figure) are installed at the bottom, sides, and / or top of the protective bag.

[0037] The material bag for waterway transportation in this embodiment employs a deformable rotating shaft connected in a chain shape by universal joints and a bag deformation mechanism. During use, the deformable rotating shaft is rotated by a drive mechanism outside the material bag. Since each pull rope is wound around a fixed mechanism in a set direction, the rotation of the deformable rotating shaft drives the corresponding pull rope to pull or release in different directions inside the transport bag, allowing the transport bag to deform and easily pass through various waterways. During use, the fixed structure, as needed, controls the corresponding electromagnet to be energized while rotating the deformable rotating shaft, attracting the corresponding sliding sleeve and engaging the first and second locking units together. This allows for the pulling or releasing of the pull rope corresponding to the sliding sleeve, enabling different parts of the transport bag to deform as needed, making it more flexible. For example, in areas with rapid changes from shallow to narrow waterways, a fully elevated transport bag is prone to stranding, while a flattened bag cannot pass. Therefore, the bag can be deformed segment by segment for gradual passage.

[0038] The transport bag is equipped with at least one annular airbag. In extreme cases, if the transport bag is damaged, the annular airbag will be inflated to divide the transport bag into multiple chambers, minimizing the loss. The inner ring is fixed to the outer ring of the slip ring or the second bearing. The slip ring or the second bearing is sealed and rotated with the columnar body of the corresponding universal joint to avoid interference with the rotation of the deformable shaft.

[0039] The transport bag is protected by a flexible, waterproof material on its outer side, providing secondary protection. This protective bag is sealed and fixed to the transport bag at the loading port and the first sealing bearing. A second air pipe, passing through the transport bag, connects to the interior of the protective bag and is equipped with a second solenoid valve. Inflation increases buoyancy and improves the bag's ability to pass through shallow water. Multiple connecting ropes connect the transport bag and the protective bag; inflation creates a relatively stable airbag framework, facilitating loading and unloading. A counterweight at the bottom of the transport bag, combined with the inflation of the transport bag and / or protective bag, further maintains the bag's upright posture when its height increases due to deformation, preventing it from tipping over. Deflating the bag, along with the pull rope controlling its flattened shape, further reduces its height. The outer surface of the transport bag is equipped with pressure sensors, liquid level sensors, and / or temperature sensors to monitor for leakage and temperature, providing data for subsequent intervention. Monitoring cameras are installed at the bottom, sides, and / or top of the protective bag to further monitor the bag and enable intervention measures to be taken.

[0040] In other embodiments, unlike Embodiment 1, the fixed structure is a universal joint column. Four pull ropes are fixed and wound around the corresponding column. Two of them are radially horizontally distributed and wound clockwise around the corresponding column, and the other two are radially vertically distributed and wound counterclockwise around the corresponding column. When the deformable shaft rotates clockwise, the radially horizontally distributed pull ropes are gradually released, and the vertically distributed pull ropes are gradually pulled. The transport bag gradually flattens on the water surface, the draft decreases, and the height of the transport bag becomes smaller, making it easier to pass through shallow water areas or the arches of low bridges. When the deformable shaft rotates counterclockwise, with some air filling the transport bag, the transport bag gradually becomes taller in the vertical direction and narrower in the horizontal direction, making it easier to pass through narrow waters and very flexible in use.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
