Embodiment Construction
[0032] The accompanying drawings show specific embodiments of the present invention.
[0033] See attached figure 1 . The sensing device is composed of an independent water flow sensor and a water level sensor. The water flow sensor and the water level sensor are connected together through their respective external sleeves. The water flow sensor is placed horizontally and the water level sensor is placed vertically.
[0034] See attached figure 2 . The water flow sensor is composed of a water flow impulse induction frame 3 , a stay cord 4 and a dynamometer 5 , and the water flow impulse induction frame 3 is connected with the dynamometer 5 through the stay cord 4 . The water impulse sensing frame is a metal cylinder with two different opening sizes, the opening facing upstream is larger than the opening facing downstream. The stay cord 4 is connected to the water flow impulse induction frame and the dynamometer, and the stay cords can be 3, 4, 6, or 8 according to the siz...

A torrential flood sensing device is composed of an independent water flow sensor and an independent water level sensor jointly. The water flow sensor is formed by a water flow impulsive force sensing frame, a pull rope and a dynamometer, wherein the flow impulsive force sensing frame is connected with the dynamometer through the pull rope. A sliding rod assembly and a dynamometry internal resistance wire ring are installed in a fixed sleeve of the dynamometer, a force spring is sleeved on the sliding rod assembly, and one ends of a sliding brush and a sliding rod are both installed on a spring supporting ring at the tail end of the sliding rod. The water level sensor is formed by a water level follow-up device, a water level sleeve and a water level internal resistance wire ring. The water level follow-up device is provided with a floater and a gravity drop-hammer, two ends of the sliding pull rope are respectively connected with the gravity drop-hammer and the floater through a fixed pulley on the water level sleeve, and the dynamometer and the sliding brush in the water level follow-up device are both connected with the internal resistance wire rings. When water flow or water level changes, the position of the spring or the gravity drop-hammer changes to cause displacement of the sliding brush contacted with the resistance wire ring, and resistance of the change is output. The torrential flood sensing device is simple, practical, capable of forecasting disasters and easy to popularize.
Description
(1) Technical field [0001] The invention relates to geological disaster monitoring, in particular to a mountain torrent sensing device. (two), background technology [0002] In the mountainous and hilly areas of our country, many natural disasters such as flash floods and mudslides occur every year, causing huge losses to people's lives and properties. Prediction and forecasting of flash floods is particularly important. Sichuan University Journal, Volume 42, 2010, Supplement 1: 155-160, "Several Suggestions on Mountain Flood Prevention and Flood Prevention and Early Warning System Construction" written by Huang Hua et al., describes the main monitoring methods for mountain torrent prevention and control at present, from It can be seen from the article that in terms of monitoring means, there is no suitable flash flood sensor to warn and forecast the occurrence and development of flash floods. (3) Contents of the invention [0003] The object of the present invention is ...
