[0002] With the updating of educational philosophies and the diversification of teaching methods, more and more educators are beginning to seek teaching tools that are both educational and engaging. As an important means of transportation in human history, the development of shipbuilding and navigation technologies contains a wealth of scientific knowledge and historical wisdom.

[0003] However, most existing ship-themed building models are primarily toys, with simple designs, limited functions, and a lack of deep integration with historical technology and educational content. These models often only possess basic external forms and fail to showcase the essence of ancient shipbuilding and navigation technology. In the field of education, especially science education, existing ship-themed building models are insufficient to meet teaching needs and cannot effectively help students understand the scientific principles and historical value of ancient navigation technology.

[0004] To address the aforementioned issues, this utility model document proposes a science education building block themed around Zheng He's treasure ship. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing ship-themed building blocks, which are simple in design, lack internal realism, and are not deeply integrated with science and technology, thus failing to meet the needs of science education. Therefore, this invention proposes a Zheng He treasure ship-themed science education building block.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A set of science education building blocks themed around Zheng He's treasure ships includes:

[0008] The hull includes a bottom compartment fixedly installed at its bottom, and the bottom compartment has multiple watertight compartments inside.

[0009] It also includes an anchor body and a winch body, the winch body being fixedly installed on the top of the ship's deck, and the anchor body and the winch body being connected by a connecting rope;

[0010] It also includes a first mast assembly and a second mast assembly, both of which are located on the top of the hull. The first mast assembly consists of a Chinese-style rigid sail model, a first mast base, and a lifting device. The second mast assembly consists of another Chinese-style rigid sail model, a second mast base, a main mast, and a sail fixing device.

[0011] It also includes two oar devices, both of which rotate through one side of the hull for simulating rowing;

[0012] It also includes a perforated rudder device, which is embedded in the bottom of the stern. The perforated rudder body of the perforated rudder device is located at the bottom of the hull, and the control part of the perforated rudder device is located at the top of the hull. The perforated rudder body and its control part are connected by bearings and bevel gear sets. The perforated rudder device is used to simulate a perforated rudder and its operation.

[0013] In one possible design, the oar device comprises a first crank, a handle, a bolt connector, an oar body, and a blade.

The second rotating shaft rotatably passes through one side of the bracket wall panel. A second bevel gear is fixedly installed at one end of the second rotating shaft, and a first bevel gear is fixedly installed at the top end of the first rotating shaft. The first bevel gear and the second bevel gear mesh with each other. Four rudder handles are fixedly installed at the other end of the second rotating shaft. The four rudder handles are used to drive the perforated rudder body to rotate.

[0015] In one possible design, the first mast mount includes a first base, a bushing, and a cross-axis mast. The first base is fixedly mounted on the top of the hull. The bushing rotatably passes through the top of the first base. The bottom end of the cross-axis mast is fixedly passed through the bushing. A connecting block is fixedly mounted on the top of the cross-axis mast. A second sail fixing component is fixedly mounted on one side of the connecting block. A sail lifting rod is slidably fitted onto the outer wall of the cross-axis mast. The sail lifting rod is located between the bushing and the connecting block. First sail fixing components are fixedly mounted on both ends of the sail lifting rod. The two first sail fixing components are located on opposite sides of the cross-axis mast and are on the same horizontal line. The sail fixing component and the two first sail fixing components are all matched with the mounting holes on one side of the Chinese hard sail model to complete the installation of the Chinese hard sail model; the lifting device includes two annular components set on the sail lifting mast, the two annular components are respectively located on both sides of the cross-axis mast, and the top of the cross-axis mast is rotatably mounted with a pulley through a bracket. The pulley and the two annular components are matched with external cables to realize the lifting and lowering of the sail lifting mast, thus completing the simulated lifting and lowering of the Chinese hard sail model; the outer wall of the cross-axis mast is fixedly fitted with four connecting parts, the four connecting parts are located below the sail lifting mast, and the four connecting parts are used to drive the cross-axis mast to rotate, thereby changing the direction of the sail.

[0016] In one possible design, the second mast mount consists of two second bases, a rotating base, and a pin. The two second bases are of different heights and are both fixedly installed on the top of the hull. The rotating base is rotatably installed between the two second bases. The main mast is fixedly installed on the top of the rotating base. A sail fixing device is fixedly installed at the top of the main mast. The main mast has multiple positioning holes inside, each corresponding to one side of the higher second base. The pin passes through the corresponding positioning hole and one side of the second base to position the main mast.

[0017] In one possible design, the winch body consists of a winch base, a second crank, and a winch disc. The winch base is fixedly installed on the top of the hull, and the winch disc rotates through the winch base. The second crank is fixedly sleeved on the outer wall of the winch disc and is located inside the winch base to simulate the winding of the connecting rope. The anchor body consists of an anchor crown and an anchor shank. Two anchor claws are integrally connected to the bottom end of the anchor shank. The anchor crown is fixedly installed on the top end of the anchor shank and has a through hole for connecting to the connecting rope. A stabilizing rod is fixedly sleeved on the outer wall of the anchor shank. A raised brick is fixedly installed on one side of the hull for fixing the anchor body in place.

[0018] In this application, when the building block model is used in teaching, the instructors can demonstrate and operate the various parts of the model, or let the students assemble the various parts by hand, which helps the students to better understand the various technological elements of Zheng He's treasure ship.

[0019] During the operation of the anchor body and the winch body, the instructor can remove the anchor body, rotate the winch in the winch body to lower the anchor body, rotate the winch in the opposite direction and wind up the connecting rope through the second crank to raise the anchor body. After the experiment, the anchor body can be fixed back on the convex brick.

[0020] When operating the first mast device, instructors can rotate the four connecting parts, which in turn drives the cross-axis mast to rotate. At this time, the connecting block and the sail lifting rod can rotate synchronously, which can simulate the adjustment of the sail's orientation to adapt to different wind directions. Simultaneously, the sail lifting rod can move up and down along the cross-axis mast, which in turn drives the lower part of the sail to move up and down. Instructors can pull down the corresponding cable by pulling down the pulley to realize the operation of furling the sail.

[0021] During the operation of the second mast device, after the instructor removes the pin, the main mast can be lowered by rotating the seat, which can simulate the situation where the main mast needs maintenance; after the maintenance is completed, the main mast only needs to be erected and fixed with the pin again.

[0022] During the operation of the two oar devices, instructors can simulate the propulsion and steering functions of a traditional oar by rotating the first crank, which helps students better understand the usage of a traditional oar.

[0023] In the operation of the perforated rudder device, instructors can rotate the four rudder discs on the deck, and then through the connection and transmission of bevel gear sets and multiple shafts, the rotation of the perforated rudder body and the two-hole bricks can be realized to simulate the control of a traditional perforated rudder.

[0024] In the design of the hull bottom compartments, through intuitive compartment division, students can clearly understand how multiple watertight compartments separate the hull space to prevent water from spreading to other areas after the compartments are flooded, thereby improving the ship's survivability and safety. This allows students to further understand the technological thinking in traditional shipbuilding.

[0025] Beneficial effects: The Zheng He treasure ship-themed science education building blocks described in this utility model are based on the records of Zheng He's treasure ship technology in ancient books. The building block model carefully selects and integrates technological components related to shipbuilding and maritime navigation, such as multi-hole rudder devices, oar devices, and watertight compartments, successfully reproducing the wisdom of ancient navigation technology. This not only allows students to intuitively experience the advanced technology of ancient ships, but also deepens their understanding of historical technology.

[0026] In this invention, a science education building block themed around Zheng He's treasure ship is designed to closely integrate the model with scientific knowledge from textbooks, making it convenient for teachers to use in classroom teaching. By demonstrating and manipulating the various parts of the model, instructors can vividly explain the relevant scientific principles and historical background, helping students to better understand and master the relevant knowledge points.
