Description

Technical Field

[0001] This utility model relates to the field of earthquake alarm model technology, and in particular to an earthquake alarm model with educational significance. Background Technology

[0002] An earthquake alarm model is a simulated or simplified version of a device used for demonstration and educational purposes, designed to mimic the functionality of an actual earthquake alarm system. This model is typically not intended to provide alerts during a real earthquake, but rather to help people understand the basic principles of earthquake monitoring and early warning.

[0003] In existing earthquake alarm models, sensors detect ground vibrations, and an alarm is triggered when the vibrations exceed a preset threshold. However, existing earthquake alarm models only provide an understanding of the principles of earthquake monitoring and early warning, making it difficult for students to intuitively understand how different amplitudes, frequencies, and propagation speeds of seismic waves affect the structure of objects. Furthermore, it is difficult to conduct detailed data analysis, resulting in a lack of opportunities for students to practice scientific research skills such as data interpretation and hypothesis testing.

[0004] Therefore, there is a need to provide an educational earthquake alarm model that allows for intuitive observation of vibration amplitude through scales and indicator boards, enabling students to understand the impact of seismic wave amplitude on building structures, thus having educational significance. Utility Model Content

[0005] To overcome the shortcomings of existing earthquake alarm models, which only explain the principles of earthquake monitoring and early warning, preventing students from intuitively understanding how different amplitudes, frequencies, and propagation speeds of seismic waves affect the structure of objects and hindering detailed data analysis, thus depriving students of opportunities to practice scientific research skills such as data interpretation and hypothesis testing, this utility model provides an educational earthquake alarm model. Through a ruler and indicator board, the vibration amplitude can be intuitively observed, enabling students to understand the impact of seismic wave amplitude on building structures, thus having educational significance.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: an educational earthquake alarm model, comprising a support platform, a testing platform, connecting plates, guide rods, support seats, return springs, hooks, an earthquake alarm model body, a base, mounting seats, and pull rings. Two connecting plates are fixedly attached to the support platform, and two guide rods are fixedly attached to the connecting plates. Support seats are slidably mounted on each of the four guide rods. A testing platform is fixedly connected between the four support seats. Return springs are sleeved on the guide rods, with both ends of the return springs connected to the testing platform and the connecting plates, respectively. Hooks are fixedly attached to the testing platform, and pull rings are hung on the hooks. Mounting seats are rotatably mounted on the pull rings. The earthquake alarm model body is mounted between two mounting seats, and a base is fixedly connected to the earthquake alarm model body. The model also includes a scale and an indicator plate. A scale is fixedly attached to the support platform, and an indicator plate is fixedly attached to the testing platform, with the indicator plate sliding within the scale.

[0007] Furthermore, it is particularly preferred that the device also includes a lead screw, a driven gear, a transmission gear, and a chuck. The transmission gear is rotatably mounted on the base and passes through the base. The driven gear is rotatably mounted on the base and meshes with the transmission gear. The lead screw is fixedly connected to the driven gear, and the chuck is threaded onto the lead screw.

[0008] Furthermore, it is particularly preferred that the device also includes sliding blocks and dampers, with multiple sliding blocks slidably arranged on the testing platform and multiple sliding blocks slidably arranged on the support platform, and a damper arranged between two adjacent sliding blocks between the testing platform and the support platform.

[0009] Furthermore, it is particularly preferred that the device also includes a vibration motor, with two vibration motors mounted on the support platform.

[0010] In addition, it is particularly preferred that a protective sleeve is included, with the pull ring fitted with a protective sleeve.

[0011] In addition, it is particularly preferred that the base also includes an anti-slip pad, which is embedded in the base.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By observing the position of the indicator board on the ruler, students can intuitively understand the magnitude of the vibration amplitude, which makes it easier for students to understand the impact of the vibration amplitude on objects and facilitates data analysis, thus having educational significance.

[0013] 2. By turning the transmission gear, the transmission gear meshes with the driven gear, causing the driven gear to drive the lead screw to rotate. This causes the lead screw to drive the chuck on its own to move upward, thereby fixing the striking ball on the earthquake alarm model body and preventing it from moving unnecessarily due to external vibrations during transportation or storage.

[0014] 3. By installing sliding blocks and dampers on the support platform and the testing platform, the impact of external forces on the model can be reduced during transportation. Attached Figure Description

Detailed Implementation

[0022] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] Example 1: An educational earthquake alarm model, see [link / reference] Figures 1-5As shown, the system includes a support platform 1, a testing platform 2, a connecting plate 3, guide rods 4, support seats 5, return springs 6, hooks 7, the earthquake alarm model body 8, a base 9, a mounting seat 10, and a pull ring 11. Connecting plates 3 are welded to both sides of the support platform 1. Guide rods 4 are symmetrically welded to the bottom of the connecting plates 3. Support seats 5 are slidably mounted on each of the four guide rods 4. The testing platform 2 is fixedly connected between the four support seats 5. Return springs 6 are fitted onto the guide rods 4, and both ends of the return springs 6 are connected to the testing platform. The platform 2 is connected to the connecting plate 3. The top of the testing platform 2 is equipped with a hook 7 by welding. A pull ring 11 is hung on the hook 7. Both ends of the pull ring 11 are rotatably equipped with mounting seats 10. The two mounting seats 10 are connected by bolts to install the earthquake alarm model body 8. The bottom of the earthquake alarm model body 8 is fixedly connected to the base 9. It also includes a scale 13 and an indicator plate 14. The scale 13 is fixedly connected to the front side of the middle of the support platform 1. The indicator plate 14 is fixedly connected to the front side of the middle of the testing platform 2. The indicator plate 14 slides within the scale 13.

[0024] See Figure 2 As shown, it also includes a vibration motor 21, which is installed symmetrically on the bottom of the support platform 1 by means of bolt connection.

[0025] See Figures 1-4 As shown, it also includes a protective sleeve 12, which is fitted onto the pull ring 11.

[0026] When demonstrating the earthquake alarm, students can participate manually, increasing interactivity. During the experiment, students first press down on the testing platform 2. The platform moves downwards, causing the four support seats 5 and the indicator plate 14 to move downwards as well, compressing the return spring 6. Releasing the platform causes the spring 6 to rebound, moving the platform and its components up and down, generating vibration. By observing the position of the indicator plate 14 on the scale 13, students can intuitively understand the magnitude of the vibration, facilitating their understanding of the impact of vibration on objects and enabling data analysis—all of which are educational. The generated vibration causes the earthquake alarm model 8 to sound an alarm. Students can then learn the basic principles of earthquake monitoring and early warning through the model. The vibration motor 21 automatically simulates the vibration effect, reducing manual operation. The protective sleeve 12 protects the pull ring 11, preventing wear between the hook 7 and the pull ring 11 due to friction.

[0027] Example 2: Based on Example 1, refer to Figures 3-6As shown, it also includes a lead screw 15, a driven gear 16, a transmission gear 17, and a chuck 18. The transmission gear 17 is rotatably arranged in the front part of the base 9 and passes through the base 9. The driven gear 16 is rotatably arranged in the middle part of the base 9. The driven gear 16 meshes with the transmission gear 17. The lead screw 15 is fixedly connected to the top of the driven gear 16. The chuck 18 is threaded onto the lead screw 15.

[0028] See Figure 2 As shown, it also includes a sliding block 19 and a damper 20. The front and rear sides of the testing platform 2 are symmetrically equipped with sliding blocks 19, and the front and rear sides of the support platform 1 are symmetrically equipped with multiple sliding blocks (19). A damper 20 is provided between two adjacent sliding blocks 19 between the testing platform 2 and the support platform 1.

[0029] See Figure 2 As shown, it also includes an anti-slip pad 22, which is embedded in the bottom of the base 9.

[0030] When the earthquake alarm model is not needed, the earthquake alarm model body 8 is removed and placed at the bottom of the testing platform 2. The anti-slip pad 22 increases the friction between the base 9 and the testing platform 2, preventing the earthquake alarm model body 8 from shifting position and being bumped during transportation. By turning the transmission gear 17, the transmission gear 17 meshes with the driven gear 16, causing the driven gear 16 to drive the lead screw 15 to rotate, which in turn drives the lead screw 15 to move the clamp 18 on its own upward, thereby fixing the striking ball on the earthquake alarm model body 8 and preventing it from moving unnecessarily due to external vibration during transportation or storage. After fixing, by opening the sliding block 19 and the damper 20 on the support platform 1 and the testing platform 2, the impact of external forces on the model can be reduced during transportation.

[0031] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
