Description

Technical Field

[0001] The utility model belongs to the technical field of educational equipment, and in particular relates to a drowning safety teaching aid. Background Art

[0002] Drowning safety teaching aids are educational tools primarily used by primary and secondary school students. Existing drowning safety teaching aids primarily rely on single audio playback, lacking a practical display device. Furthermore, there are no devices or equipment that can provide different audio instructions based on a pedestrian's position or behavior. Improving the real-life effects of drowning safety teaching aids has been a topic of research for those skilled in the art.

[0003] Chinese invention patent No. 201910433303.5 discloses a swimming teaching aid for preventing drowning, comprising a support with a sloping bottom pool, a grating bottom step, a clean water flow, and a mobile diving platform. The grating bottom step is located on the surface of the support with a sloping bottom pool, the clean water flow is located on the middle surface of the support with a sloping bottom pool, and the mobile diving platform spans parallel tracks on the left and right sides of the top of the support with a sloping bottom pool. The grating bottom step, which can instantly float up, completely eliminates students' fear of drowning and provides students of different heights with a foothold at an appropriate depth for breaststroke learning and a grip for learning to swim underwater. Students can fully and quickly experience the natural buoyancy of water in the human body and learn to swim in half an hour. The invention has a simple structure, is appropriately precise, and has a low manufacturing cost. It is safe, reliable, and foolproof when used on the ground. It can be disassembled and reassembled anywhere, without occupying a permanent site. The pool water is chlorine-free and similar to high-quality mineral water, eliminating the need for frequent pool water changes, greatly saving water resources. This swimming teaching aid for preventing drowning mainly simulates the scene of learning to swim and does not provide warnings and education on drowning safety. Utility Model Content

[0004] The utility model provides a drowning safety teaching aid with a simple structure, good real-scene education demonstration effect, and sensitive position response of a simulation human model.

[0005] A drowning safety teaching aid includes a pool model formed by a floor panel, a first side panel, a second side panel, steps, and a pool bottom panel. The pool model is provided with a first water depth area panel, a second water depth area panel, and a third water depth area panel representing different water depths. The pool bottom panel, the first water depth area panel, the second water depth area panel, and the third water depth area panel are all mounted on the back of a circuit control board. The circuit control board is provided with a control circuit that senses the position and movement of a humanoid model. A magnet is provided at the bottom of the humanoid model. The magnet senses a sensing switch in the control circuit, which triggers a speaker in the control circuit to emit voice information about the area where the humanoid model is located. This drowning safety teaching aid uses the first water depth area panel, the second water depth area panel, the third water depth area panel, and the pool bottom panel to coordinate with the position and movement of the humanoid model to emit voice information about different areas, thereby providing real-world scenario-based drowning safety education and improving the effectiveness of warning education.

[0006] The first side panel and the second side panel are both L-shaped, and the pool model forms a concave observation notch at the connecting end of the first side panel and the second side panel, thereby increasing the observation area of the pool model to better adapt to the real pool environment.

[0007] The inductive switch is a reed switch. When the magnet at the bottom of the humanoid model approaches the reed switch and the magnetic force of the magnet exceeds the elastic force of the reed of the reed switch itself, the two reeds will attract and conduct the circuit to play the voice in the corresponding position area.

[0008] The control circuit includes a control chip, which is respectively connected to the first pin connector, the second pin connector, and the digital-to-analog converter. The digital-to-analog converter circuit is connected to the speaker. The second pin connector is connected to an induction circuit formed by two or more induction switches connected in parallel.

[0009] The utility model sends voice information of different areas by coordinating the position of the first water depth area plate, the second water depth area plate, the third water depth area plate and the pool bottom plate with the movement of the simulated human model, conducts field scene-type drowning safety knowledge education, and improves students' safety awareness.

[0015] The following is combined with Figure 1-4 The specific implementation method further describes the technical solution of this patent in detail.

[0016] A drowning safety teaching aid includes a pool model formed by a floor panel 1, a first side panel 12, a second side panel 4, steps 3, and a pool bottom panel 8. The first side panel 12 and the second side panel 4 are both L-shaped. The pool model is equipped with a first water depth area panel 5, a second water depth area panel 6, and a third water depth area panel 7 representing different water depths. A circuit control board 10 is mounted on the back of the pool bottom panel 8, the first water depth area panel 5, the second water depth area panel 6, and the third water depth area panel 7. The circuit control board 10 includes a control circuit that senses the position and movement of a humanoid model. A magnet is installed at the bottom of the humanoid model. The magnet senses a sensor switch 19 in the control circuit, which triggers a speaker 17 in the control circuit to emit voice information indicating the humanoid model's location. A warning sign 2 is mounted on the floor panel 1.

[0017] In order to increase the environmental consistency between the drowning safety teaching aids and the drowning scene and facilitate educational observation, the pool model forms a concave observation notch at the connecting end of the first side panel 12 and the second side panel 4.

[0018] In order to improve the sensing sensitivity, the sensing switch 19 is a reed switch 11 , the number of the reed switches 11 is more than two, and a single set of sensing circuits is connected in parallel.

[0019] As a preferred structure, the control circuit includes a control chip 13, which is respectively connected to a first pin connector 14, a second pin connector 16, and a digital-to-analog converter 15. The digital-to-analog converter 15 is connected to a speaker 17. The second pin connector 16 is connected to an induction circuit formed by two or more induction switches 19 connected in parallel.

[0020] When the humanoid model stays or moves to the first water depth area plate 5, the second water depth area plate 6, the third water depth area plate 7, and the pool bottom plate 8, the induction switch sends a signal to the control chip, and the control chip sends different warning voices according to the position of the humanoid model.

[0021] For example, when the simulated human model stands on the first water depth area board 5, triggering the corresponding sensor switch 19, a warning voice is broadcasted, saying that the model is currently at the edge of the pool, please be careful. When the simulated human model moves to the second water depth area board 6, triggering the corresponding sensor switch 19, a warning voice is broadcasted, saying that the model is currently in the diving area of the pool, please be careful. When the simulated human model moves to the third water depth area board 7, triggering the corresponding sensor switch 19, a warning voice is broadcasted, saying that the model is currently in the deep water area of the pool, please be careful. When the simulated human model moves to the bottom board 8 of the pool, triggering the corresponding sensor switch 19, a warning voice is broadcasted, saying that the model is currently at the bottom of the pool, you are drowning, thereby achieving different warning and educational effects.

[0022] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
