Abstract

The utility model relates to the field of the water conservancy and flood control, in particular to an alarm device for monitoring the abrupt change of a water level. In order to solve the technical problem that the traditional water level monitoring device cannot directly represent the change of the water level, the utility model provides the alarm device for monitoring the abrupt change of the water level. The technical scheme of the alarm device is as follows: the alarm device for monitoring the abrupt change of the water level comprises a buoy level meter, an acceleration sensor 3 and an alarm device 1, wherein the buoy level meter comprises a buoy 5 and a link rod 4, the buoy 5 is connected to the lower end of the link rod 4, the acceleration sensor 3 is connected to the upper end of the link rod 4, and the alarm device 1 is connected with the acceleration sensor 3 through a lead wire 2. The alarm device has the following beneficial effects that 1, the monitored results are visualized and visible, and whether the water level has a larger change can be monitored without needing long-term data accumulation and complex calculation, therefore, the efficiency is improved and the alarm device has an important significance on disaster prevention and reduction as well as the investigation of environmental change; 2, the alarm device has simple structure and low production cost; and 3, the labor intensity of water conservancy staff and the cost for labor force are reduced.

Description

The mutation of water level monitoring alarm

Technical field

The utility model relates to water conservancy flood control field, particularly a kind of mutation of water level monitoring alarm.

Background technology

At present, the buoy level meter widespread use as the forecast SEA LEVEL VARIATION can not characterize the variation of water level but it can only characterize the numerical value of water level intuitively.When making that because of disaster or artificial origin the water level of river or ocean changes suddenly, often can not monitor intuitively, but need just can draw by the computing of lot of data accumulation by buoy level meter.So just may miss an opportunity because of a delay, cause the generation of great disaster.So, just need a kind of device that can directly monitor mutation of water level.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of mutation of water level monitoring alarm that can directly monitor SEA LEVEL VARIATION.

The technical solution of the utility model is: a kind of mutation of water level monitoring alarm comprises buoy level meter, acceleration transducer 3 and alarm 1.Described buoy level meter comprises buoy 5 and gangbar 4.The lower end of described gangbar 4 connects buoy 5, and the upper end connects acceleration transducer 3.Described alarm 1 links to each other with acceleration transducer 3 by lead 2.

Described alarm 1 is one or more in electric bell or hummer or the alarm lamp, the combination of preferred alarm lamp and electric bell or alarm lamp and hummer.

When the water level in river changed, the variation of water level can drive the buoy that swims in the water surface and move up and down, and is delivered to acceleration transducer by gangbar, when acceleration surpasses certain numerical value, started alarm equipment alarm.

The beneficial effects of the utility model are: 1, monitoring result intuitively as seen, do not need just can to monitor water level whether bigger variation is arranged by long term data accumulation and loaded down with trivial details computing, the shortening time, raise the efficiency, point out the variation of environment, the variation of preventing and reducing natural disasters and investigate environment is had great importance; 2, simple in structure, cost of manufacture is cheap; 3, reduce water conservancy working personnel's labor capacity, reduced human cost.

Embodiment

Specify the utility model below in conjunction with drawings and Examples.

Embodiment 1:

Referring to Fig. 1, the utility model comprises buoy level meter, acceleration transducer 3 and alarm 1.Buoy level meter comprises buoy 5 and gangbar 4.The lower end of gangbar 4 connects buoy 5, and the upper end connects acceleration transducer 3.Alarm 1 links to each other with acceleration transducer 3 by lead 2.

Described alarm 1 is the combination of alarm lamp and electric bell.

The course of work of the present utility model is as follows: when water level changes, the variation of water level can drive the buoy 5 that swims in the water surface and move up and down; the gangbar 4 that moves through of buoy 5 is delivered to acceleration transducer 3, when acceleration surpasses certain numerical value, starts alarm 1 and reports to the police.

Embodiment 2:

Except that the combination of preferred hummer of alarm and alarm lamp, other are with embodiment 1.
