Solar earthquake water wave alarm device

Abstract

The invention relates to earthquake early-warning and alarm equipment, specifically a solar earthquake water wave alarm device. The upper part of a cylinder cover (22) is provided with an alarm loudspeaker (19), and the upper part of the interior of a cylinder (1) is provided with a lateral support (7). The lateral support (7) is fixedly connected with the cylinder (1) through a nut (8), and the interior of the cylinder (1) is provided with a spring (6) which is connected with the center of the lateral support (7). The lower end of the spring (6) is connected with a closed sphere (13) through a contact protection cover (5). The lowest point of the closed sphere (13) is provided with a suspension wire (15), and one end, passing through one end of a hollow cylinder (11) below the closed sphere (13), of the suspension wire (15) is connected with a suspension hammer II (16). The interior of the contact protection cover (5) is provided with a contact pin (17). The beneficial effects of the invention lie in that the device is simple in structure, is convenient to operate and install, is high in sensitivity, is accurate in alarm and early warning, is wide in application range, is charged through solar energy, and saves resources.

Description

technical field [0001] The invention relates to the technical field of earthquake early warning and alarm equipment, in particular to a solar earthquake water wave alarm device. Background technique [0002] Earthquake is the most ferocious enemy of human beings. The direct disasters it causes include: damage to buildings and structures, such as house collapse, bridge breakage, dam cracking, rail deformation and so on. Ground damage, such as ground cracks, subsidence, water spraying sand, etc. Destruction of natural objects such as mountains, such as landslides and landslides. Huge waves caused by tsunamis and submarine earthquakes wash up on the coast, causing damage to coastal areas. Accurately predicting the occurrence of earthquakes is a major problem facing scientists all over the world. However, if people can detect and quickly avoid earthquakes when they occur, the loss of life and property can be greatly reduced, especially when earthquakes occur at night. . The ...

Problems solved by technology

There are many instruments used for earthquake alarm at present, but they all use the principle of balance. When the balance is unbalanced, the alarm power is connected. There are pendulums, pendulum needles, and some are equipped with springs or magnets, but the sensitivity is not high. When the balance is restored, the alarm will be released. Adding magnets can easily cause misleading, and most of these alarms have complex structures and high manufacturing costs.

[0003] And the existing earthquake alarm device not only has low sensitivity, but also wastes resources in the use process, and the early warning and alarm accuracy is relatively low, so it is not widely used.
