Summary of the invention
The purpose of this utility model is in order to solve employed miniature, low-cost, an earthquake alarm problem that sensitivity is higher such as family, office, to provide a kind of reasonable in design, the earthquake alarming device that simply stablize, cost is low.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of earthquake alarming device, comprise the tower seat, be positioned at the body of the tower on the tower seat, and the warning room that is positioned at the body of the tower top, it is characterized in that being provided with stand type support in the described body of the tower, the stand type support top is provided with the platform of horizontality, place a steel ball on the platform, one end of steel ball and a rope is fixed, and the other end of rope is connected with the switch that is arranged on the steel ball top, and warning is provided with alarm in the room.The relative body of the tower in tower seat bottom surface designs largerly, and to place steadily, the height of body of the tower is guaranteeing that under the prerequisite that each functional safety is realized, profile is by standard design attractive in appearance; The xsect of stand type support is less than the platform area, and platform is made circle, and size and the steel ball of its diameter match; When the length of rope guarantees that steel ball breaks away from platform, the Drawing switch by steel ball weight freely falling body, alarm adopts the module of capable of choosing multiple sound.
As preferably, be provided with the concave arc sphere in the plane of described platform, the degree of depth of concave arc sphere is less than or equal to 2mm, and the diameter of concave arc sphere and the diameter of steel ball match.When platform was adjusted to horizontality, concave arc location at spherical surface steel ball remained static to keep steel ball.
As preferably, the length of described rope greater than switch to the distance between the platform.When steel ball tumble flat after the time, then drive switch by steel ball pulling rope, make switch be in engagement state, thereby send warning.
As preferably, the link of described switch and rope is positioned at outside the top, edge of platform.The rope Drawing switch spurs vertically downward, and rope does not directly contact with platform when work, in order to avoid friction damage.
As preferably, described platform position is provided with level(l)ing device.Before using or before the refitting, must adjust the level of platform, to guarantee the warning precision.
As preferably, described body of the tower is right cylinder or polygon shuttle-shaped column body structure.Guarantee the structural strength of body of the tower, and a kind of warning device attractive in appearance is provided.
As preferably, be provided with the accumulator mounting box in the described tower seat, the tower seat is provided with external electric supply socket.This structure can be selected by multiple power sources, such as dry cell, civilian electricity etc., the configurable potential device of external power supply.The power supply place arranges master switch in addition, can turn off first master switch when reporting to the police, with power saving or wrong report.
As preferably, described switch has auto-reset function.When steel ball working once after, when again steel ball being placed into platform, switch automatically resets.
As preferably, described body of the tower is provided with access door.Access door can be placed the usefulness of steel ball, inspection, maintenance.
The beneficial effects of the utility model are: the domestic type volume is little, and precision sensitivity is high, installation, placement, easy to use, and integrated cost is low.
