Embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.
Embodiment one
A kind of water-level control apparatus that is used for water tower sees figures.1.and.2, and comprises substrate 1, L shaped fork 4, first ball float 2, second ball float 3 and the touch switch 5,6 that is used to control the pumping motor start-stop.The end on the long limit 41 of this L shaped fork 4 is first end of L shaped fork 4, and the end of minor face 42 forms second end of L shaped fork 4, and the middle part on this length limit 41 is articulated on the described substrate 1, and thus, this L shaped fork 4 is arranged on the substrate 1 swingably.
Two extreme positions about the swing of above-mentioned L shaped fork 4 has, described touch switch 5,6 is installed in two extreme positions of L shaped fork 4 first ends swing respectively, that is to say, when L shaped fork 4 first ends swing to extreme position, can trigger touch switch 5 or 6.
Described first ball float 2 is fixedly connected on second end of described L shaped fork 4, described second ball float 3 is connected in second end of described L shaped fork 4 by a tightrope 7, the quality of described second ball float 3 is greater than first ball float 2, first ball float 2 is a hollow ball, its density is near air, second ball float is a medicine ball, and its density is slightly less than water.
In addition, also comprise a locating device that is used to make described L shaped fork 4 swings and is positioned two limit positions.This locating device comprises a spring 8, and an end of this spring 8 is connected on the substrate 1, and the other end connects the following position of 41 pivoting points, described L shaped fork 4 long limits.
With reference to Fig. 1, when water level is in lowest order, second ball float 3 is second end of the L shaped fork 4 of pulling downwards, make first end touch switch 5 beats to the left of L shaped fork 4, before swinging to the centre position, spring 8 hinders L shaped fork 4 swing and accumulation of energys, after swinging to the centre position, spring 8 releases energy and makes L shaped fork 4 quicken swing, trigger this touch switch 5 at last, and under the effect of spring 8, in the process that water level is upwards raise by low level, L shaped fork 4 stably is in this state; With reference to Fig. 2, when being increased to first ball float, 2 places, also continues when rising to most significant digit water level, the buoyancy that water produces first ball float 2 promotes first end touch switch 6 beats to the right of L shaped fork 4, before swinging to the centre position, spring 8 hinders L shaped fork 4 swing and accumulation of energys, after swinging to the centre position, spring 8 releases energy and makes L shaped fork 4 quicken swing, trigger this touch switch 6 at last, and under the effect of spring 8, in the process that water level is reduced downwards by a high position, L shaped fork 4 stably is in this state.
