The switch control of detection device；Can also be further, water storage tank connected pump in front, rear, left and right is two or more, pumps and opens
It is connected with controller between pass, quickly adjusts.
Also need to illustrate has: can also indicate that inclined degree with a hanger, why not use a weight as
Detection device? the reason is that: weight indicates that the efficiency of minimum point is too low: when run-off the straight, weight: 1, it needs one longer
Time reach new nadir or/and 2, after weight reaches new minimum point, to swing.Water of the present invention
Flat detection device quick rotation, the frequency for detecting minimum point can be very high, moreover, will not swing, retrieval precision and frequency
Significantly larger than Weight type detection device.In addition: filament used in weight cannot obviously extend, and length of the weight apart from suspension point is not
Become, length of the ball 8 away from motor shaft of the present invention is variation, moreover, just having extreme length in vertical position.
Motor shaft head is fixedly connected with the swingle 4 vertical with its axis, and swingle is equipped with vertical to the motor axis
Sliding slot 5, such technical characteristic can greatly improve the precision of detection, the reason is that: spring 7 and ball 8 have the intrinsic frequency of vibration
F1, motor rotation has specific frequency f2, because f2 and f1 are inconsistent, if being easy for causing without sliding slot 5 and swingle 4
The confusion of winding and detection frequency.There are a sliding slot 5 and swingle 4,8 diriven motion of ball, in other words, the technology that sliding slot is solved
Problem or the technical effect reached: 1, it prevents from winding.2, so that detection frequency is determined as motor rotation frequency.
It is in summary only present pre-ferred embodiments, all equivalent modifications done according to the application and prior art addition are equal
It is considered as the technology of the present invention scope.
