Technical Field

[0001] This utility model relates to the field of teaching model technology, and in particular to a teaching model ship. Background Technology

[0002] Teaching model ships are a convenient teaching tool that allows students to intuitively understand the structure and working principles of ships. However, existing model ships are usually just three-dimensional or cross-sectional models and do not have actual functions. Therefore, students can only learn about the structure of the ship and imagine its actual working principles. Such ship models cannot intuitively demonstrate its working principles. In particular, the setting and operation of various functional structures in the cabin is a major challenge in teaching. For example, in the simulation teaching of hull leakage testing, how to determine whether the hull is leaking and how to design the hull structure to prevent leakage, or in the simulation teaching of hull buoyancy testing, how to determine the buoyancy of the hull, etc. Existing model ships cannot provide intuitive experimental demonstrations, which is not conducive to improving the quality of teaching. Utility Model Content

[0003] In view of the above, it is necessary for this utility model to provide a teaching model ship that is easy to demonstrate intuitively for use in experiments and observations, so as to improve the quality of teaching.

[0004] The technical solution of this utility model is as follows:

Several partition plates are erected on the bottom surface of the hull, dividing the bottom plate into several sealed compartments. Water inlet holes are opened on the side walls of the outer perimeter of the hull corresponding to each sealed compartment, and plugs are installed in the water inlet holes. A deck is laid on the top of the partition plates on the hull, dividing the hull into upper and lower layers. The leak detection mechanism includes an electronic control main board, monitoring components electrically connected to the electronic control main board, and warning lights. The monitoring components are installed in each sealed compartment according to the number of compartments, and are used to detect water entering the corresponding sealed compartment and trigger the warning light alarm. The waterline and displacement water level line are marked on the outer perimeter of the hull.

[0006] Furthermore, each set of monitoring components includes a water accumulation sensor and a warning light strip. The water accumulation sensor is fixed to the bottom of the sealed compartment, and the warning light strip is fixed to the upper surface of the deck, corresponding to the water accumulation sensor above and below.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0019] Please see Figure 1 and Figure 2 A model boat for teaching purposes includes a hull 10 and a leak detection mechanism 20 installed inside the hull 10. The hull 10 is made of transparent panels, and the joints between adjacent panels are filled with waterproof transparent adhesive for bonding.

[0020] A plurality of partition plates 11 are erected on the inner bottom surface of the hull 10, and the partition plates 11 are arranged at intervals along the length of the hull 10, dividing the inner bottom plate of the hull into a plurality of sealed compartments 12. Water inlets are opened on the side walls of the outer perimeter of the hull 10 corresponding to each sealed compartment 12, allowing water to flow into the sealed compartment 12 through the water inlets. Preferably, the water inlets are opened at the bottom end of the sealed compartment 12, and the water inlets are provided with plugs 13 for sealing or opening the water inlets. A deck 14 is laid on the top of the partition plates 11 on the hull 10, and the deck 14 covers the sealed compartments 12, dividing the hull 10 into upper and lower layers, preventing water from entering the sealed compartments 12 and entering the entire hull 10, thereby compromising the buoyancy of the hull 10 and causing the hull 10 to sink.

[0021] Understandably, the deck 14 can be made up of several sealing plates spliced ​​together, with each sealing plate correspondingly covering the top of a sealed compartment 12. During teaching, when it is necessary to put an object into the sealed compartment 12, the sealing plate at the top of the corresponding sealed compartment 12 can be opened.

[0022] The leak detection mechanism 20 includes a power supply 21, an electronic control main board 22, several monitoring components 23, and a warning light 24. The power supply 21 and the electronic control main board 22 are fixed in the upper layer of the hull 10, and the power supply 21 supplies power to the electronic control main board 22. There are multiple monitoring components 23, which are respectively installed in each sealed compartment 12 and electrically connected to the electronic control main board 22 to detect whether water has entered the corresponding sealed compartment 12. The warning light 24 is installed at the top of the hull 10 and electrically connected to the electronic control main board 22. When any monitoring component 23 detects water entering the sealed compartment 12, the electronic control main board 22 will receive a signal and activate the warning light 24 to light up and alarm. In this embodiment, preferably, a light stand 15 is provided at the bow of the hull 10, and the warning light 24 is fixed on the light stand 15 so that it can attract attention in time when it is lit.

[0023] In this embodiment, in order to accurately identify whether water has entered the corresponding sealed compartment 12, each monitoring element 23 includes a water accumulation sensor 231 and an alarm light strip 232. The water accumulation sensor 231 is fixed to the bottom of the sealed compartment 12, and the alarm light strip 232 is fixed to the upper surface of the deck 14, corresponding to the water accumulation sensor 231 above and below. When the water accumulation sensor 231 detects water entering the sealed compartment 12, the alarm light strip 232 is activated to illuminate to indicate that water has entered the sealed compartment 12 directly below.

[0024] Furthermore, to facilitate clear visibility of the water level within the sealed compartment 12, the monitoring component 23 also includes a lighting strip 233. The lighting strip 233 is fixed to the top surface inside the sealed compartment 12. Preferably, in this embodiment, a slidable, openable transparent waterproof plate 16 is installed at the top of the sealed compartment 12. The waterproof plate 16 is located above the water inlet, dividing the sealed compartment 12 into an upper and lower double-layer structure. The lighting strip 233 is installed on the waterproof plate 16 to prevent it from being submerged after water enters the sealed compartment 12. Understandably, both the warning light strip 232 and the lighting strip 233 are electrically connected to the main control board 22 via wires (not shown).

[0025] Furthermore, several wiring holes 141 are provided on the deck 14 so that the power supply wire can be inserted into the wiring hole 141 and connected to the water accumulation sensor 231 and the lighting strip 233. After the wire is inserted into the wiring hole 141, waterproof transparent glue is filled in the gap between the wiring hole 141 and the wire to improve the sealing of the hull 10.

[0026] Furthermore, a control console 17 is provided at the stern of the hull 10. A counterweight is placed on the control console 17 to balance the weight at both ends of the hull 10, so as to float stably in the water. The control console 17 is equipped with a switch 25 for controlling the power supply 21 and the main control board 22 to control the on / off state of the main control board 22.

[0027] Understandably, the warning light 24, the warning light strip 232, and the lighting strip 233 can emit different colors of light in order to accurately distinguish the light-emitting components and the meaning of the information they convey.

[0028] Furthermore, the waterline and displacement water level are marked on the outer hull of the ship (not shown in the figure).

[0029] In the teaching of the buoyancy experiment of simulating the hull 10, the hull 10 is placed smoothly in the water, and then one of the plugs 13 is pulled out to allow water to flow into the corresponding sealed compartment 12 through the water inlet. The state change of the hull 10 is observed. Subsequently, other plugs 13 can be pulled out to allow water to enter and observe the sinking and floating changes of the hull 10. During the experiment, the water in the sealed compartment 12 can also be drained to refer to the relationship between the displacement water level line and buoyancy.

[0030] During the simulated water leakage experiment of the ship hull 10, the ship hull 10 is placed steadily in the water. The switch 25 is pressed to connect the power supply 21 to the main control board 22. Then, one of the plugs 13 is briefly pulled out to open the water inlet and supply water into the corresponding sealed compartment 12. Subsequently, the water accumulation sensor 231 detects the water in the sealed compartment 12 and outputs a signal to the main control board 22. Then, the main control board 22 sends a signal, and the warning light 24, the warning light strip 232 corresponding to the water accumulation sensor 231, and the lighting strip 233 will light up. In this way, the teaching can be carried out intuitively and clearly.

[0031] In teaching, the method is as follows: The teaching model ship can be tentatively named the Fujian Ship Model.

[0032] (I) Demonstration of the principle of ship floating

[0033] 1. Operating steps: Gently place the homemade Fujian ship model into the prepared water tank, ensuring that the water surface is calm and undisturbed.

[0034] 2. Observation points: Guide students to carefully observe the stable floating state of the Fujian ship model in the water, understand and record the balance relationship between the buoyancy and gravity of the ship at this time, that is, the buoyancy is equal to the gravity, which makes the ship float.

[0035] (II) Demonstration of the effect of cargo transport by compartment on a ship

[0036] 1. Operating steps: Place counterweights of different masses in each compartment of the Fujian ship model to simulate cargo loading in actual transportation.

[0037] 2. Observation Points: Guide students to observe and record how the stability of the ship is affected by changes in the mass of the counterweights, and the corresponding changes in the waterline. This experiment helps students understand the importance of compartment design for the efficiency and safety of ship transportation.

[0038] (III) Demonstrating the relationship between the ship's draft and displacement water level.

[0039] 1. Operating steps: Using the waterline and displacement water level marked on the hull, the water level changes of the ship under different loads are simulated by gradually adding counterweights to the water tank.

[0040] 2. Observation points: Guide students to carefully observe and record the changes in the draft and displacement water level as the water level rises, and to gain a deeper understanding of the close relationship between displacement and buoyancy, that is, as the displacement increases, the buoyancy also increases to keep the ship floating.

[0041] (iv) Comparative demonstration of the performance of the empty ship and Fujian ship models under leaking conditions.

[0042] 1. Operating Procedures: Prepare an empty ship model without watertight compartments for comparison, while keeping the self-made Fujian-style ship model floating normally. Then, simulate the situation where both ships leak water simultaneously, observe and record their reactions.

[0043] 2. Observation Points: Guide students to conduct a detailed analysis of the forces acting on an empty ship without watertight compartments and a self-made Fujian ship model with watertight compartments after water leakage. When an empty ship without watertight compartments leaks, the buoyancy force quickly becomes less than the weight, causing the ship to sink rapidly. Conversely, in the self-made Fujian ship model, due to its unique watertight compartment design, even if a compartment leaks, only the water volume in that compartment increases. Thus, buoyancy and weight remain in balance, meaning buoyancy equals weight, allowing the Fujian ship model to continue floating. Through this comparative experiment's force analysis, the crucial role of watertight compartments in preventing ship sinking can be profoundly emphasized. They not only improve ship safety but also demonstrate the wisdom and innovation of ancient navigation technology.

[0044] (V) Demonstration of the watertight compartment leakage alarm mechanism

[0045] 1. Operating steps: Simulate a water leak in a sealed compartment of the Fujian ship model, and trigger the water accumulation sensor by injecting water into the compartment.

[0046] 2. Observation Points: Guide students to carefully observe how the water sensor quickly triggers the corresponding lighting strip above the sealed compartment to illuminate when it detects moisture, while the circular lighting strip on the deck of the Fujian ship (i.e., warning light 24) also lights up, forming a clear leak alarm signal. Through this experiment, students can intuitively experience the application of technology in ship safety.

[0047] (vi) Demonstration of the effect of ballast water in watertight compartments on ship balance

[0048] 1. Operating procedure: Slowly add an appropriate amount of water as ballast water to a specific watertight compartment of the Fujian ship model, while keeping other compartments dry.

[0049] 2. Observation Points: Guide students to carefully observe and record how the ship tilts and its stability changes as ballast water is added. By adjusting the amount of ballast water in different compartments, further explore the important role of ballast water in regulating the ship's balance and maintaining navigational stability. This experiment helps students gain a deeper understanding of the complexity and intricacy of ship design.

[0050] In addition, the other effects of this teaching model ship and the requirements for experimental equipment are as follows:

[0051] (I) Simulating Fujian-style ships to inherit traditional culture and inspire national pride

[0052] Through meticulous design and production of Fujian-style ships, the unique appearance of ancient Chinese ships was not only recreated, but students also gained a deep understanding of the glorious achievements of ancient Chinese maritime technology. The demonstrations and explanations guided students to understand the historical background, technological characteristics, and important position of Fujian-style ships in world maritime history, thereby inspiring their national pride and love for traditional culture.

[0053] (ii) Transparent hull design, visually showcasing the water intake process.

[0054] The hull is constructed using transparent acrylic material, allowing students to clearly and intuitively observe the water ingress into the sealed compartments. During simulated leakage experiments, students can witness firsthand how water gradually seeps into the compartments and the changes in buoyancy and gravity during this process, thereby deepening their understanding of the conditions for an object to float and sink.

[0055] (III) Integrating sensors and lighting strips to enhance the interactivity and fun of the experiment.

[0056] The Fujian-style ship model integrates water sensors and LED lighting strips. When a leak occurs in a compartment, the sensor immediately detects the moisture and triggers the corresponding lighting strip to illuminate. Simultaneously, the ring-shaped lighting strip on the deck also lights up, creating a clear alarm signal. This not only enhances the interactivity and fun of the experiment but also allows students to intuitively experience the application of technology in ship safety monitoring, stimulating their interest in science and technology.

[0057] (iv) Integrating interdisciplinary teaching to enhance comprehensive literacy

[0058] The design of this experimental setup fully embodies the concept of interdisciplinary integration, closely combining the principles of buoyancy in physics, maritime culture in history, and design and manufacturing in engineering technology. By guiding students to participate in the making and experimental demonstration of the Fujian ship model, they not only deepened their understanding of physics but also broadened their knowledge horizons and enhanced their interdisciplinary comprehensive literacy. At the same time, students were encouraged to apply their learned knowledge to innovative designs, further cultivating their practical abilities and innovative thinking.

[0059] (v) Adjustable counterweight system to simulate different load conditions

[0060] An adjustable counterweight system was designed into the Fujian-style ship model. By adding or removing counterweights, the buoyancy and sinking of the ship under different load conditions were simulated. This made the experiment more realistic, allowing students to observe the stability of the ship and changes in the waterline under different loads, gain a deeper understanding of the relationship between buoyancy and gravity, and the impact of load on the safety of ship navigation.

[0061] In addition, the characteristics can be supplemented by demonstrating teaching aids:

[0062] 1. Experiment on the linkage between water leakage scenario and intelligent alarm

[0063] Comparative experiment: Water was simultaneously injected into an empty ship without compartments and a Fujian ship model. The empty ship sank rapidly, while the Fujian ship only sank its compartments after being injected with water, but floated as a whole.

[0064] Intelligent alarm: When water is injected into a compartment of the Fujian ship, the sensor is triggered, and the corresponding lighting strip and ring lighting strip light up, so that the alarm system can help the crew quickly locate the leak.

[0065] Record the difference in sinking speed between the two ships and analyze how the "watertight compartment" maintains buoyancy balance by limiting the range of water ingress.

[0066] By making intuitive comparisons, we highlight the value of technological innovation and combine circuit principles to understand the synergistic mechanism of "structural protection + intelligent monitoring".

[0067] 2. Integrated Experiment of Compartment Design and Ballast Balance

[0068] The model of the Fujian ship demonstrates its compartmentalized structure. When only the left side compartment is loaded with cargo, the ship tilts and the counterweight is adjusted to restore balance.

[0069] Step 1: Place a 100g counterweight in the left compartment, observe the model tilting to the left, and record the tilt angle.

[0070] Step 2: Add an appropriate amount of ballast water to the right compartment and observe the model gradually return to its upright position.

[0071] Through asymmetric load experiments, the impact of compartment design on transportation efficiency and navigation safety is demonstrated, and the "controlled variable method" is applied.

[0072] Through experiments with Fujian-style ships, students can gain a deeper understanding of the balance between buoyancy and gravity, and clearly explain the principle behind watertight compartment technology in maintaining ship stability. During the model design and optimization process, students can develop creative thinking, propose innovative structures for simplified Fujian-style ships, and improve their designs through critical analysis.

[0073] Through studying and analyzing Fujian-style ships, students develop a strong interest in ancient navigation techniques. The experimental classes enhance students' national pride and allow them to appreciate the wisdom of traditional culture.

[0074] Through interdisciplinary integration, students can combine physics knowledge with engineering technology in laboratory classes and add cultural elements to their models. The mineral water bottle model is inexpensive, meets the design requirements of a simple ship, and has high potential for widespread adoption.

[0075] In summary, the teaching model boat provided by this utility model divides the hull 10 into upper and lower layers by setting a deck 14, and the lower layer of the hull 10 is divided into several independent sealed compartments 12 by installing an isolation plate 11, and several monitoring components 23 are set to cooperate with the corresponding sealed compartments 12, so that leakage and buoyancy tests can be carried out intuitively, which effectively improves the teaching quality.
