Description

Earthquake alarming device

Technical field

The utility model relates to a kind of earthquake alarming device, relates in particular to a kind of applicable to the employed earthquake alarming device of small field such as family, office.

Background technology

Earthquake is least foreseeable disaster, and people can't predict the time that earthquake takes place accurately at present, can not accurately predict great earthquake disaster takes place, and causes heavy losses often for human lives and properties.But earthquake still can early warning, use alarm to detect usually and catch seismic signal and in time send earthquake pre-warning, thereby reminds people in time take refuge, thereby avoid or reduce casualty loss.Existing alarm structure is more complicated all, and it is bulky, the price height, only be applicable to large-scale special environment such as seismological bureau, be unsuitable in town and country extensively popularizing and promoting, and China to be an earthquake frequently send out the more country in district, be in the peak period of earthquake outbreak in recent years, so, carry out the earthquake defensive measure and seem very important, but be not fit to the earthquake alarming device cheaply that use in family expenses or minimized office place at present.

The utility model content

Technical problem to be solved in the utility model provides a kind of earthquake alarming device, and it is simple in structure, and is with low cost, is suitable for family and small-sized place and uses.

For solving the problems of the technologies described above, the technical solution of the utility model is: earthquake alarming device, comprise an alarm generation circuit, described alarm generation circuit comprises direct supply, loudspeaker and the ground of series connection make described alarm generation circuit connect when rocking recloser, described recloser comprises the conductive seat of a horizontal positioned, and described conductive seat is connected with an electrode of described direct supply; A horizontally disposed conductive ring, described conductive ring is connected with another electrode of described direct supply, described conductive ring is supported on the described conductive seat by bracing or strutting arrangement, and described bracing or strutting arrangement insulate with described conductive ring and described conductive seat respectively; Be placed on the semicircle spheroid of the conduction on the described conductive seat, vertically be fixed on the conducting rod on the described semicircle spheroid, described conducting rod inserts in the described conductive ring.

As a kind of improvement, be provided with timing relay in the described alarm generation circuit.

As further improvement, described bracing or strutting arrangement is provided with and is used to adjust the vertically height adjustment mechanism of height of conductive ring.

As further improvement, described bracing or strutting arrangement is provided with the position adjusting mechanism that is used to adjust the conductive ring horizontal level.

Owing to adopted technique scheme, earthquake alarming device is connected the conductive seat of horizontal positioned with an electrode of direct supply; The horizontally disposed conductive ring that is supported on the conductive seat by bracing or strutting arrangement is connected with another electrode of direct supply; Bracing or strutting arrangement insulate with conductive ring and conductive seat respectively; Be placed on the conductive seat by semicircle spheroid conduction, then conducting rod is inserted in the described conductive ring, and then the series connection loudspeaker form a loop, under normal circumstances, because conductive ring and conducting rod are in discontiguous state, so form a normal open circuit.When earthquake takes place, the rolling that the semicircle spheroid can be random on conductive seat during earth shock, and the rolling of semicircle spheroid can drive conducting rod comprehensive waving in conductive ring, it is contacted with conductive ring, form the loop of a closure, thereby the connection loudspeaker sends alerting signal, and reminds people is taken refuge.Because it is relatively simple for structure, and with low cost, thus be fit to promote the use of on a large scale, especially, simple and practical for family or office space.

Embodiment

As depicted in figs. 1 and 2, earthquake alarming device, direct supply 1, loudspeaker 2 and ground make described alarm generation circuit connect when rocking recloser 4 series connection formation alarm generation circuit, recloser comprises the conductive seat 5 that a horizontal positioned is connected with an electrode of direct supply, is fixedly connected with first support bar 51 on 5 on the conductive seat; One is horizontally disposed with the conductive ring 6 that is connected with another electrode of direct supply, and conductive ring 6 is fixedly mounted on the conductive seat 5 by second support bar 61; Be fixedly connected with insulation sleeve 9 between first support bar 51 and second support bar 61; Under normal circumstances they constitute a normal open circuit.And when earthquake takes place, because the vibrations on ground, the semicircle spheroid 7 of the conduction that is placed on the conductive seat 5 is rolled, the conducting rod 8 that drive is arranged in the conductive ring 6 waves, thereby the conducting rod 8 that vertically is fixed on the semicircle spheroid 7 is contacted with conductive ring 6, alarm generation circuit is connected, and loudspeaker 2 sends alerting signal.

In alarm generation circuit timing relay 3 is set, after making conducting rod 8 and conductive ring 6 contacting communication line, can keeps on-state within a certain period of time, make loudspeaker 2 send alerting signal continuously, reminds people is taken refuge.

Height adjustment mechanism be insulation sleeve 9 with first support bar 51 and second support bar 61 between be threaded, perhaps adopt the mechanism of pegging graft and increasing set nut, in a word, be convenient to adjust the vertical height of conductive ring 6.In addition, on second support bar 61, position adjusting mechanism 62 is set, is used for adjusting the horizontal level of conductive ring 6.The purpose that above-mentioned two adjusting mechanisms are set is by adjusting the height and the position of conductive ring 6, make conducting rod 8 be in the center of conductive ring 6 all the time, keeping the sensitivity to all directions vibrations.

Be fixed with the position-limiting cover 10 that described semicircle spheroid 7 is covered on the described conductive seat 5, be convenient to like this it is in the certain limit all the time semicircle spheroid 7 location, prevent that when excessive vibrations conducting rod 8 breaks away from conductive ring 6.
