Problems solved by technology

However, the dripping speed of water droplets is directly related to the level of the water level. The higher the water level, the greater the pressure of the outlet hole, and the faster the dripping speed of the water droplets; when the water level is getting lower and lower, the pressure of the outlet hole also changes Small, the speed of the water drop will slow down, because the pressure of the outlet hole will change with the change of the water level, so that the drip speed of each drop of water cannot be the same as the time interval, which greatly affects the accuracy of the water clock

Embodiment Construction

[0007] Attached below figure 1 The present invention is described in detail.

[0008] A water clock teaching aid, comprising a water tank 1, an outlet pipe 3, a rack with floating blocks 7, a gear 5, a pointer 6, and a dial 4, characterized in that there is a floating block 8 on the water tank 1, and the floating block 8 is a side opening, There is a water outlet hole 2 at the bottom of the floating block 8, and the water outlet hole 2 is connected with the water outlet pipe 3. Since the floating block has been floating on the water surface, the height of the water outlet hole and the water surface of the floating block will never change. Also unchanged, effectively solved the isochronism problem of how to make the drop speed of each drop of water all the same.

Abstract

The invention relates to a water clock, in particular to a water clock teaching aid for primary school science. The water clock teaching aid comprises a water tank, a water outlet pipe, a rack provided with a floating block, a gear, a pointer and a dial plate, and is characterized in that the floating block is arranged on the water tank, the floating block is provided with an opening in the side face, the bottom of the floating block is provided with a water outlet hole, and the water outlet hole is connected with the water outlet pipe. The water clock teaching aid has the advantages that change of pressure intensity of the water outlet hole caused due to lowering of the water level is effectively avoided due to the fact that water dripping is achieved without the need of directly drilling a hole in the bottom of the water tank; the water outlet pipe is connected with the water outlet hole of the floating block due to the fact that the floating block is adopted, the floating block floats on the water surface all the time, the water outlet hole of the floating block and the height of the water surface are unchanged, so that the water outlet hole of the floating block and the height of the water surface are unchanged even if the water level is lowered, pressure intensity of the water outlet hole keeps unchanged, water outlet speed is unchanged, and the problem of isochronism of water drops is effectively solved.

Description

technical field [0001] The invention relates to a water clock, in particular to a water clock teaching aid for elementary school science. Background technique [0002] The third section of the third unit of "Measurement of Time" in the second volume of the fifth grade of the primary school science textbook introduces the water clock, which uses water droplets to measure time. However, the dripping speed of water droplets is directly related to the level of the water level. The higher the water level, the greater the pressure of the outlet hole, and the faster the dripping speed of the water droplets; when the water level is getting lower and lower, the pressure of the outlet hole also changes Small, the speed of the water drop will slow down, because the pressure of the outlet hole will change with the change of the water level, so that the drip speed of each drop of water cannot be the same as the time interval, which greatly affects the accuracy of the water clock.
