Also to be noted are: the degree of tilt can also be indicated by a suspension, why does not use a weight as the detection device? The reason is that: the weight indicates that the efficiency of nadir is too low: when the inclination occurs, the weight: 1, it takes a longer time to reach the new lowest point, or/and 2, after the weight reaches the new lowest point, the swing should occur. The horizontal detection device provided by the invention can rotate quickly, the frequency of the lowest point can be very high, the lowest point cannot swing, and the retrieval precision and frequency are far higher than those of a weight type detection device. In addition: the thin line used by the weight can not be obviously extended, the length of the weight from the suspension point is constant, the length of the ball 8 from the motor shaft is variable, and the ball has the longest length in the vertical position.
Motor spindle nose fixedly connected with and axis vertically rotary rod 4 are equipped with on the rotary rod with motor axis vertically spout 5, and such technical characteristics can improve the precision that detects greatly, and the reason is: the spring 7 and the ball 8 have a natural frequency f1 of vibration, and the motor rotation has a specific frequency f2, because f2 and f1 are not consistent, which easily causes confusion of winding and detecting frequencies if the sliding chute 5 and the rotating rod 4 are not provided. With the chute 5 and the rotary rod 4, the ball 8 is forced to move, in other words, the technical problem solved by the chute or the technical effect achieved: 1, preventing winding. And 2, determining the detection frequency as the motor rotation frequency.
In summary, the present invention is only a preferred embodiment, and all equivalent modifications and additions made by the present application are considered to be within the technical scope of the present invention.
