Embodiment
Embodiment of the present invention 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 said 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; Said 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.
Said first ball float 2 is fixedly connected on second end of said L shaped fork 4; Said second ball float 3 is connected in second end of said L shaped fork 4 through a tightrope 7; The quality of said second ball float 3 is a hollow ball greater than first ball float, 2, the first ball floats 2, and its density is near air; Second ball float is a medicine ball, and its density is slightly less than water.
In addition, comprise that also one is used to make said L shaped fork 4 to swing and be positioned the locating device of 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 position below 41 pivoting points of said L shaped fork 4 long limits.
With reference to Fig. 1, when water level was 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, triggers 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, and 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, and 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.
Above-mentioned touch switch 5,6 is used to control the start-stop of pumping motor, and concrete control mode can depend on the needs.This shows that this device can come the start-stop of control pumping motor automatically according to the extreme position of water level, thereby reach the purpose of control water tower level.
