Description

Technical Field

[0001] The utility model relates to the technical field of teaching instruments, in particular to a water flow optical fiber experiment device capable of controlling the curvature of a water column. Background Art

[0002] Fiber optic transmission is a technology that uses optical fibers to transmit information, based on the principle of total internal reflection of light. Fiber optic transmission is a key topic in middle school physics. To help students more intuitively grasp this concept, teachers often demonstrate it through experiments, and using water flow to simulate fiber optic light transmission is one common method.

[0003] However, existing water flow simulations for optical fiber light-guiding experiments have shortcomings. The curvature of the water column flowing out of the outlet changes continuously as the liquid level in the container drops, and it cannot always maintain a specific curvature. Therefore, the teacher cannot ensure that many students observe the same phenomenon, which increases the difficulty for students to understand. Multiple experiments will also disrupt the teacher's lecture rhythm. Utility Model Content

[0004] The purpose of the utility model is to provide a water flow optical fiber experiment device capable of controlling the curvature of a water column, so as to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A water flow fiber optic experiment device capable of controlling the curvature of a water column comprises a container for holding water, the upper end of the container being open, a first water outlet pipe and a second water outlet pipe being connected to the container respectively, the first water outlet pipe being arranged at a higher height than the second water outlet pipe, and a fixing clip for fixing a laser pen being provided on the second water outlet pipe, and the laser pen being fixed so as to point to the water outlet of the second water outlet pipe.

[0012] In the above technical solution, the utility model provides a water flow fiber optic experiment device capable of controlling the curvature of a water column, which has the following beneficial effects:

[0013] Water is continuously added to the container through the first water outlet pipe and the second water outlet pipe. Water exceeding the height of the first water outlet pipe is discharged from the first water outlet pipe. At this time, the liquid level in the container is maintained at the first water outlet pipe, so that the water pressure at the second water outlet pipe remains stable, and the curvature of the water column flowing out of the second water outlet pipe remains stable.

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] See also Figure 1-3 A water flow fiber optic experiment device that can control the curvature of a water column includes a container 1 for holding water, the upper end of the container 1 is open, and a first water outlet pipe 11 and a second water outlet pipe 12 are respectively connected to the container 1. The first water outlet pipe 11 is set at a height greater than the setting height of the second water outlet pipe 12. The second water outlet pipe 12 is provided with a fixing clip 13 for fixing a laser pen, and the fixed laser pen points to the water outlet of the second water outlet pipe 12.

[0024] Continuously add water into the container 1, and the water exceeding the height of the first water outlet pipe 11 is discharged from the first water outlet pipe 11. At this time, the liquid level in the container 1 is maintained at the first water outlet pipe 11, so that the water pressure at the second water outlet pipe 12 remains stable, and the curvature of the water column flowing out of the second water outlet pipe 12 remains stable. The laser pen emits a laser toward the outlet of the second water outlet pipe 12, so that the laser can be observed in the outflowing water column. The teacher does not need to repeat the experiment many times, and many students can observe the same experimental phenomenon, which improves the efficiency of classroom demonstration and is easy for students to understand intuitively.

[0025] Furthermore, the second water outlet pipe 12 includes a first horizontal pipe 120 connected to the container 1, the end of the first horizontal pipe 120 is connected to the first vertical pipe 121, the end of the first vertical pipe 121 is connected to the second horizontal pipe 122, the first horizontal pipe 120 is fixedly connected to the fixed frame, and the laser pen points to the central axis of the second horizontal pipe 122.

[0026] The water in the container 1 passes through the first horizontal tube 120 and the first vertical tube 121 in sequence and flows out from the second horizontal tube 122 to form a water column. The laser pointer points to the central axis of the second horizontal tube 122 so that the laser can be observed in the water column.

[0027] Furthermore, a regulating valve 2 is installed on the first horizontal pipe 120. The regulating valve 2 can adjust the flow of the second water outlet pipe 12, and the experiment is highly controllable, which is convenient for teachers to explain.

[0028] Furthermore, the first vertical tube 121 and the second horizontal tube 122 are made of transparent material, so that the light emitted by the laser pen can pass through the first vertical tube 121 and the second horizontal tube 122 and is convenient for students to observe.

[0029] Furthermore, the apparatus includes a placement plate 3 having a water trough 31 defined therein. The container 1 is placed within the water trough 31. A water pump 32 is fixedly mounted within the water trough 31 and connected to a water inlet pipe 34 on the container 1 via a connecting pipe 33. Water flowing out of the second water outlet pipe 12 falls into the water trough 31 and, under the action of the water pump 32, enters the container 1 through a hose and the water inlet pipe 34, thus forming a water recycling system. This eliminates the need for the teacher to manually add water, further reducing the difficulty of experimental operation. The placement plate 3 is provided with a safety socket for convenient connection to an external fixed or mobile power source to power the water pump 32.

[0030] Furthermore, the placement plate is provided with a lifting platform 4, on which the container 1 is fixedly mounted. The lifting platform 4 can be a linear actuator (hydraulic cylinder, pneumatic cylinder) and a support plate, or it can be a multi-rod lifting support platform as shown in the accompanying drawings. Both are conventional techniques and are commonly used by those skilled in the art, and will not be described in detail. The lifting platform 4 can elevate the container 1, allowing the water column to fall from a higher position, allowing students to better observe it.

[0031] Working principle: Start the water pump 32 to continuously supply water to the container 1. Water that exceeds the height of the first water outlet pipe 11 is discharged from the first water outlet pipe 11. At this time, the liquid level in the container 1 is maintained at the first water outlet pipe 11, so that the water pressure at the second water outlet pipe 12 remains stable. The curvature of the water column flowing out of the second water outlet pipe 12 remains stable. The laser pen emits a laser toward the central axis of the second horizontal tube 122, so that the laser can be observed in the outflowing water column. The teacher does not need to repeat the experiment many times, and many students can observe the same experimental phenomenon, which improves the efficiency of classroom demonstrations and is easy for students to understand intuitively. The utility model can maintain the stability of the curvature of the water column and can adjust the curvature independently. In addition, the initial height of the water column outlet can also be adjusted, which increases the adaptability of the experiment to classroom explanations and expands the operational range of extended experiments.

[0032] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
