Abstract
The utility model belongs to teaching instruments and particularly relates to a demonstration instrument for hydraulic power generation. The demonstration instrument comprises a water collection tank (1) and a water reservoir (2) positioned above the water collection tank (1), a water pump (5) is arranged in the water collection tank (1), a pipeline (6) is arranged between the water pump (5) and the water reservoir (2), a DC generator (7) and an electric motor (9) are arranged on the water collection tank (1) and mutually connected through a lead wire, impellers (8) are arranged on the DC generator (7) and positioned below the water reservoir (2), and a windmill (10) is arranged on the electric motor (9). The demonstration instrument provided by the utility model has a simple structure, is convenient and easy to operate, has obvious effects, enables students to visually observe the energy conservation law and the energy conversion phenomenon, and enriches the teaching contents and the teaching means.
Description
Technical field
The utility model belongs to instruments used for education, particularly a kind of hydropower demonstrator.
Background technology
Law of conservation of energy and energy conversion phenomenon are the emphasis and the difficult points of physics teaching in secondary school.Secondary school teachers is bound a bead through cord commonly used when this problem of explanation, allow it illustrate as simple harmonic motion.Say something too simply with single pendulum, in order to allow middle school student that law of conservation of energy and energy conversion phenomenon are had better perceptual knowledge, exploitation hydropower demonstrator has the comparison realistic meanings.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of hydropower demonstrator is provided, and this demonstrator can reflect law of conservation of energy and energy conversion phenomenon intuitively.
To achieve these goals, the technical solution of the utility model is as follows: a kind of hydropower demonstrator, it comprises water-accepting tank, cistern, and cistern is positioned at the top of water-accepting tank, and water pump is set in the water-accepting tank, between water pump and the cistern pipeline is set, Dyn. and motor are set on the water-accepting tank, and Dyn. is connected by lead with motor, and impeller is set on the Dyn., impeller is positioned at the below of cistern, and windmill is set on the motor.
During the demonstration beginning, get to cistern by the water in the pump handle water-accepting tank, kinetic energy is converted into potential energy.Water gets off to impact impeller from cistern, and impeller is rotated, and potential energy is converted into kinetic energy.The rotating band dynamotor generating of impeller, kinetic energy is converted into electric energy, and the electricity that Dyn. produces rotates the windmill that is installed on the motor, and electric energy is converted into kinetic energy.Like this, can observe law of conservation of energy and energy conversion phenomenon intuitively.
As improvement, the bottom of described cistern is provided with downcomer.
The bottom of cistern is provided with downcomer, the speed in the time of can improving the cistern water outlet, thereby the rotation of quickening impeller.
As improvement, on the described downcomer valve is set.
Valve is set on the downcomer, and valve-off in the cistern retaining discharges water after waiting cistern to expire again, has increased the potential energy of water, makes experiment effect more obvious.
As improvement, big bottom, described cistern top is little, and the top reduces gradually to the bottom.
Big bottom, cistern top is little, and the top reduces gradually to the bottom, the speed in the time of can improving the cistern water outlet equally, thus the rotation of quickening impeller makes experiment effect more obvious.
The utility model is simple in structure, operates easyly, and effect is obvious, makes the student can observe law of conservation of energy and energy conversion phenomenon intuitively, has enriched the content of courses and teaching means.
