[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0022] The following describes the frog in the well demonstration device provided by some embodiments of the present invention in conjunction with the accompanying drawings. Example

[0023] Combine Figure 1-4As shown, the frog in the well demonstration instrument provided by the present invention includes a cylinder mechanism, a camera mechanism and a drawing board mechanism. The cylinder mechanism includes a cylinder 110, a bottom plate 130 installed at the bottom end of the cylinder 110, a transparent plate 140 arranged at the bottom of the inner cavity of the cylinder 110 for separating the inner cavity of the cylinder 110, a water injection pipe 150 plugged into one side of the top of the cylinder 110, and a top ring 160 fixedly installed at the top of the cylinder 110. A fixed foot 120 is installed on the outer side of the bottom end of the cylinder 110, and the fixed foot 120 is fixedly connected to the bottom plate 130. The water injection pipe 150 is externally connected to the water injection pipe, and the inner end of the water injection pipe 150 is flush with the inner wall of the cylinder 110. The camera mechanism includes a camera 210 arranged inside the cylinder 110 and below the transparent plate 140, and a data output device for outputting the content shot by the camera 210. The data line 220, the outer end of the data line 220 passes through the cylinder 110 and is connected to the display device. The bottom end of the camera 210 is fixedly mounted on the bottom plate 130, and the top of the camera 210 does not contact the transparent plate 140. The drawing board mechanism includes a mounting ring 310 placed on the top ring 160, support rods 320 evenly distributed on the top of the mounting ring 310, and an analog drawing board 330 that is mutually engaged with the support rods 320. The center point of the analog drawing board 330 coincides with the center point of the circle of the cylinder 110. A positioning groove 161 is provided on the top ring 160, and a positioning ring 311 is sleeved in the positioning groove 161. The positioning ring 311 is fixedly mounted on the bottom end of the mounting ring 310. Positioning holes 331 are provided at the four corners of the analog drawing board 330, and the positioning holes 331 match the protruding columns at the top of the support rods 320.

[0024] Specifically, the cylinder 110 is used to simulate a water well, the camera 210 is used to simulate a frog, and the image recorded by the camera 210 is transmitted to a display device using the data cable 220, thereby realizing the simulation of a frog at the bottom of a well. While observing, water is injected through the water injection pipe 150 to simulate the rise of well water, thereby observing the changes in the frog's perspective. As the water level rises, the image observed by the frog becomes larger, and the different angles of light refraction by water and air can be understood, which facilitates teaching. In addition, the mounting ring 310 serves as a drawing board, and different patterns or information can be replaced to simulate environmental changes at the bottom of the well. When the simulated drawing board 330 rotates, the clamping action of the support rod 320 and the simulated drawing board 330 causes the pattern or information on the mounting ring 310 to rotate accordingly, thereby simulating the dynamic changes of the environment at the bottom of the well. The entire device is stably supported by the fixed foot 120, ensuring the smooth progress of the simulation process. Through the fable of the frog at the bottom of the well, it can not only attract students' interest in learning, but also enable students to quickly memorize and understand the influence of water sources on the angle of light refraction.

[0025] The working principle and usage process of the present invention are as follows: First, the cylinder 110 is installed on the base plate 130 through the fixed foot 120, and the camera 210 is put on the bottom of the cylinder 110, and then the data cable 220 is connected to the display device (such as a computer, etc.), and then the mounting ring 310 is placed on the top ring 160. After it is placed stably, the simulation drawing board 330 is aligned with the four support rods 320 and placed on it. After the installation is completed, the device is started, and the camera 210 is used to record the pattern that can currently be observed on the simulation drawing board 330. Then, water is injected into the inside of the cylinder 110 through the water injection pipe 150. As the water source increases, the pattern on the simulation drawing board 330 recorded by the camera 210 changes. According to the current changes, the changes in the refraction angle of light under different media can be intuitively observed, which is convenient for teaching.
