Description
Technical Field
[0001] This utility model relates to the field of on-the-job training technology, specifically a general cargo hold simulation device for teaching purposes. Background Technology
[0002] In port cargo handling operations, personnel must enter the ship's cargo hold to perform tasks such as stacking and securing cargo and directing machinery. This type of "under-the-hull operation" is in a complex environment with limited space, posing various safety risks such as poor visibility, cargo slippage, and mechanical collisions, requiring extremely high levels of safety awareness and operational skills from the personnel.
[0003] Traditional safety training for operations below deck relies heavily on theoretical explanations, two-dimensional drawings, or PowerPoint presentations, lacking a sense of depth and realism. This "theoretical" teaching method has significant drawbacks: Firstly, trainees struggle to visualize the actual three-dimensional structure of the cargo hold, lacking an intuitive understanding of the positional relationship between cargo and ship structures (such as bilges, sides, and longitudinals), the limitations of mechanical access routes, and potential sources of risk, resulting in a severe disconnect between training content and actual production. Secondly, instructors cannot dynamically and vividly recreate and analyze the complex operational scenarios and historical accident cases below deck, leading to low trainee participation and unsatisfactory training results.
[0004] Although some ship models exist for teaching purposes, most are closed structures, making it impossible to observe internal operational details from the outside, or they have limited functions and cannot flexibly simulate cargo layout and personnel positioning, thus failing to meet the needs for efficient and immersive safety training.
[0005] Therefore, there is an urgent need in this field for a teaching device that can intuitively, three-dimensionally, and flexibly simulate the real cargo hold operating environment. Utility Model Content
[0006] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a fully transparent material simulation device for general cargo hold, which simulates a real ship carrying general cargo and facilitates intuitive explanation of loading and unloading operations.
[0007] The technical problem to be solved by this utility model is achieved through the following technical solution: a teaching general cargo hold simulation device, comprising: A transparent substrate, with its bottom surface serving as a support surface; The transparent cargo hold shell is formed by a bow plate, a stern plate and a pair of side panels that are vertically fixed to the top surface of the transparent substrate. The ends of the bow plate, the stern plate and the pair of side panels are fixed together to form a cargo hold that simulates the loading and unloading of general cargo on a real ship in the area above the transparent substrate. Two sets of transparent cabin longitudinal ribs, each cabin side plate has a set of transparent cabin longitudinal ribs on its inner wall, each set of transparent cabin longitudinal ribs is composed of several spaced transparent longitudinal ribs, thus simulating the longitudinal ribs of a real ship. A pair of transparent bilge plates are fixed at an angle between the top surface of the transparent base plate and the bottom surface of a pair of cabin side plates to simulate the bilge of a real ship. The transparent cargo hold deck is fixed to the top of the transparent general cargo hold shell, with a loading and unloading port for general cargo in the middle, thus simulating the cargo hold opening of a real ship. Transparent hatch coaming, which is vertically fixed to the top surface of the loading and unloading port, thus simulating the hatch coaming of a real ship; A pair of transparent side panels are fixed at an angle between the transparent cabin deck and a pair of cabin side panels to simulate the hull of a real ship.
[0008] Compared with the prior art, the beneficial technical effects of this utility model are: (1) By designing a fully transparent cargo hold shell, the traditional desktop sketch explanation is upgraded to a visual three-dimensional model explanation, which builds a complete cargo hold space concept for trainees and greatly enhances the intuitiveness and three-dimensionality of teaching. In particular, the different areas inside the cargo hold have different inclinations, which directly lead to different loading volumes. The hoisting displacement feed during loading and unloading operations are also completely different. Therefore, this device can effectively solve the problem of the training content being disconnected from actual production.
[0009] (2) Through this general cargo compartment simulation device, the lecturer can give a multi-angle and all-round explanation around the model, and can freely adjust the quantity of goods, stacking method and the position of simulated personnel in the model, vividly interpret the source of safety risks, dynamically review past accident cases, thereby improving the lecturer's teaching effect.
[0010] (3) Trainees can clearly observe every corner of the cabin through a holographic perspective similar to that of a drone, and deeply understand the technical points and safety regulations of the cabin operation. The model supports manual operation and can highly restore various complex operation scenarios in the cabin, enabling trainees to learn and remember at the same time, and transform abstract knowledge such as human-machine cooperation points, risk sources and difficulties in stacking goods into concrete and vivid experience, which is beneficial to trainees' memory.
[0011] (4) The simulation device is simple in structure, low in cost, and easy to manufacture. By applying it to teaching and training, it has significantly improved the intuitiveness and immersion of the training, resulting in an increase of about 15% in the work efficiency of the trainees and a general strengthening of their safety and quality awareness and operational skills. In preliminary practice, it has successfully helped the company avoid potential safety and quality accidents and continues to play a positive role in subsequent skills education and training.

[0014] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.
[0015] Example 1, referring to Figure 1-5 A teaching-use general cargo hold simulation device, comprising: The transparent substrate 1 is formed into a roughly square plate structure. Its thickness can be selected according to the usage requirements. Its bottom surface is set as a support surface, which can be placed on a table. The transparent cargo hold shell is formed by a bow plate 2, a stern plate 3 and a pair of side plates 4 that are vertically fixed to the top surface of the transparent substrate 1, thus forming a roughly square structure. The bow plate 2, the stern plate 3 and the pair of side plates 4 are all square plate structures, and their size can be selected according to the usage requirements. The ends of the bow plate 2, the stern plate 3 and the pair of side plates 4 are fixed as one piece, thus forming a cargo hold in the area above the transparent substrate 1 that simulates the loading and unloading of general cargo on a real ship. Two sets of transparent cabin longitudinal ribs 5, each cabin side plate 4 has a set of transparent cabin longitudinal ribs 5 on its inner wall, each set of transparent cabin longitudinal ribs 5 is composed of several transparent longitudinal ribs 5 spaced apart, each transparent longitudinal rib 5 is a plate structure, thus simulating the longitudinal ribs of a real ship, the number of each set of transparent longitudinal ribs 5 can be selected according to the size of the transparent cargo hold shell. A pair of transparent bilge plates 6 are formed into trapezoidal plate structures and are fixed at an incline between the top surface of the transparent base plate 1 and the bottom surface of a pair of cabin side plates 4 to simulate the bilge of a real ship. The incline angle can be selected according to the usage requirements. The transparent cargo hold deck 7 is formed into a square plate structure and is fixed to the top of the transparent general cargo hold shell. A loading and unloading port 8 for general cargo is reserved in the middle. The port is square to simulate the cargo hold opening of a real ship. Loading and unloading operations are completed through the loading and unloading port 8. The transparent hatch coaming 9 is formed into a roughly square plate structure and is vertically fixed to the top surface of the loading and unloading port 8 to simulate the hatch coaming of a real ship. A pair of transparent side panels 10 are fixed at an angle between the transparent cabin deck 7 and a pair of cabin side panels 4, forming a square plate structure. The angle of inclination can be selected according to the usage requirements to simulate the side of a real ship.
[0016] In Example 1, the transparent cargo hold shell is used to simulate the cargo hold. The two sets of transparent ship hold longitudinal ribs 5 set on the inner wall of the transparent cargo hold shell, as well as the transparent bilge plate 6 and transparent side plate 10 placed between the transparent base plate 1, the ship hold side plate 4 and the transparent ship hold deck 7, are used to simulate the tilted and uneven internal structure of the real ship. Since the internal structure directly affects the displacement and feed of the spreader and the quantity, position and method of cargo stacking during loading and unloading operations, trainees can intuitively understand the details of loading and unloading operations at different positions in the cargo hold through this simulation device. In addition, rod-shaped or block-shaped objects of a certain size can be stacked in the cargo hold of the simulation device to simulate the loading and unloading of rod-shaped or block-shaped general cargo.
[0017] Example 2, a teaching general cargo hold simulation device described in Example 1, also includes a personnel entrance / exit 11 on the transparent ship deck 7. The personnel entrance / exit 11 can be a square opening. A transparent cargo hold ladder schematic block 12 is also fixed between the personnel entrance / exit 11 and the inner wall of the transparent general cargo hold shell to simulate the cargo hold ladder of a real ship.
[0018] In Example 2, the transparent cargo hold ladder schematic block 12 is used to simulate the cargo hold ladder inside the cargo hold. It is formed into a roughly square block structure. Its design purpose is to allow trainees to intuitively understand the specific location of the cargo hold ladder inside the cargo hold of a real ship. When loading and unloading materials, they need to pay attention to the position of the stacked goods and make reasonable avoidance when operating lifting equipment.
[0019] Example 3, a teaching general cargo hold simulation device described in Example 1, has several light sources 13 fixed on the bottom surface of the transparent ship hold deck 7, facing the interior of the cargo hold. The light sources 13 are LED light sources, which can be purchased according to the usage requirements. They are used to simulate the position of the light source 13 in the cargo hold of a real ship. The purpose is to let trainees know that when loading and unloading cargo, they need to avoid keeping a distance from the light source 13 when the lifting equipment is moved or when the general cargo is stacked.
[0020] Example 4, a teaching general cargo hold simulation device as described in Example 1, wherein the transparent longitudinal rib 5 is located between the transparent bilge plate 6 and the transparent side plate 10.
[0021] Example 5, a teaching general cargo hold simulation device described in Example 1, wherein a transparent bow transition plate 14 is fixedly provided between the end of the transparent bilge plate 6 near the bow upright plate 2 and the edge of the bow upright plate 2, and the transparent bow transition plate 14 is formed into a triangular plate structure.
[0022] In Example 5, the triangular transparent bow transition plate 14 is designed to simulate the section of the bow of a real ship with a greater inclination. Its inclination angle is greater than that of the transparent bilge plate 6. The obtuse angle between the transparent bow transition plate 14 and the transparent base plate 1 is greater than that between the transparent bilge plate 6 and the transparent base plate 1. This informs trainees that the bottom space of the cabin of a real ship is not square, but is more complex near the bow, with a more inclined or uneven structure. Therefore, special attention needs to be paid to the stacking quantity and stacking method of general cargo near the bow. It should be noted that although the simulation device is not scaled up to the actual ship, it still allows trainees to intuitively feel that the material stacking conditions in different cabin locations are different, and can still achieve the teaching purpose.
[0023] Example 6, a teaching general cargo compartment simulation device described in Example 1, wherein several transparent support plates 15 are fixedly provided between the transparent base plate 1 and the transparent bilge plate 6 to support the transparent general cargo compartment shell, and the transparent support plates 15 are formed into a generally plate-shaped structure.
[0024] In Example 6, the transparent cargo compartment shell can be supported by the transparent support plate 15, thereby improving its structural stability.
[0025] Example 7: A teaching general cargo hold simulation device described in Example 1 has several transparent reinforcing plates 16 fixedly installed on the outer walls of the bow upright plate 2 and the stern upright plate 3. These plates are formed into square plate structures and are arranged parallel to the bow upright plate 2 and the stern upright plate 3. The bottom surface of the transparent reinforcing plate 16 is fixedly connected to the top surface of the transparent base plate 1 to enhance the structural stability between the bow upright plate 2, the stern upright plate 3 and the transparent base plate 1.
[0026] Example 8, a teaching general cargo hold simulation device described in Example 1, wherein the transparent substrate 1, transparent general cargo hold shell, transparent hold longitudinal rib 5, transparent bilge plate 6, transparent hold deck 7, transparent hatch coaming 9 and transparent side plate 10 are made of transparent acrylic material.
[0027] In Example 8, a transparent acrylic material is used to build the general cargo hold simulation device. Trainees can clearly observe the space and layout inside the model from various angles, and intuitively understand the different loading volumes and stacking positions in different locations in the hold. When stacking general cargo of different shapes, the model can be used for pre-simulation, thereby maximizing the safety factor during subsequent loading and unloading operations and reducing the occurrence of accidents.
[0028] The general cargo compartment simulation device used for teaching in Examples 1-8 has an overall length of no more than 2.5 meters, a width of no more than 1.2 meters, and a height of no more than 0.4 meters. Its specific dimensions can also be customized according to the usage requirements, or are not limited to these. It is worth noting that this simulation device uses a fully transparent structure to construct a miniature cargo hold scene that can be adjusted as needed. During teaching, trainees can observe from multiple angles the impact of structural differences such as the longitudinal ribs 5, bilge, and sidewalls on the work space. The instructor uses the loading and unloading port 8 and movable simulated cargo (which can be made of 3D-printed block / rod / cylindrical / sheet materials, etc., to simulate the actual loading and unloading of cargo of different shapes) to dynamically demonstrate the stacking methods of general cargo in different positions and shapes, and analyze key operational points such as lifting paths and stacking stability. Compared with the traditional teaching method of deducing from two-dimensional drawings, the teaching effect of this device is better and more intuitive.
