Abstract
The utility model discloses a ground laying alarm device which comprises a floor 1 embedded with an alarm bell, a bottom support 2, a piezoelectric ceramic 3, a spring 4 and a piezoelectric ceramic bracket 5, and mainly solves the problem that most of alarm devices need external power and can not be powered automatically. The ground laying alarm device is specially characterized in that a groove is arranged in the ground laying alarm device and used for containing the piezoelectric ceramic, the upper surface of the piezoelectric ceramic is just contacted with the floor embedded with the alarm bell, and the edge of the whole device is connected and fixed by the spring. When the floor is subjected to pressure, the piezoelectric ceramic generates electrodynamic potential so as to lead the alarm bell in the floor to give an alarm through a lead. The device has the advantages of being small in unit area, easy to assemble and disassemble, sensitive to sense, needing no external power, being clean and environment-friendly, and meeting the conceptions of energy conservation and emission reduction.
Description
Technical field
Alarm method technical field under the present invention, warning device is laid on particularly a kind of ground.
Background technology
Known, along with the development of society, all kinds of warning devices need be installed in increasing place, but most now warning devices all needs to rely on outside energy, can't accomplish energy-autarchic.
Summary of the invention
At the problem that exists in above-mentioned, the way that the present invention proposes to solve, its technical scheme is:
Warning device is laid on a kind of ground of the present invention, by the floor 1 that is inlaid with alarm bell, bottom support bracket 2, the piezoelectric ceramics 3 between floor and the bottom support bracket, be used to connect with the spring 4 of fixed floor and bottom support bracket and fixedly the groove 5 of piezoelectric ceramics form.
The present invention can apply to that the various personnel of forbidding enter and needs are installed the place of warning system, and the gate-crasher can contact this laying apparatus by trampling, and draws the ring alarm bell immediately, and need not connect extraneous power supply.
The advantage that the present invention lays on a kind of ground warning device is: this contact warning device does not need extraneous power supply to get final product work, and induction is sensitive, and confidentiality is better.
Description of drawings
The present invention is described further below in conjunction with embodiment.
Fig. 1 is the structural representation of the automatic light-emitting floor laying apparatus of a kind of override type of the present invention.1 floor, 2 bottom support brackets, 3 piezoelectric ceramics, 4 springs, 5 piezoelectric ceramics grooves that are inlaid with alarm bell among the figure wherein.
Embodiment
With reference to the accompanying drawings, piezoelectric ceramics 3 is equipped with 1 time in the floor, and the piezoelectric ceramics upper surface contacts just with the floor lower surface, and the piezoelectric ceramics lower surface is fixed in the groove of bottom support bracket 2, fix with spring all around, piezoelectric ceramics 3 surfaces pick out the alarm bell that goes between with in the floor 1 and are connected.When floor pressurized compressing piezoelectric ceramics, piezoelectric ceramics produces electromotive force and alarm bell is reported to the police.By the ground that the laying apparatus of a plurality of units can be laid arbitrary shape, workable, be easy to mounting or dismounting.
Claims (4)
- A ground lay warning device by inside inlay alarm bell floor (1), bottom support bracket (2), place piezoelectric ceramics (3) between tempered glass and the bottom support bracket, be used for fixing the spring (4) of tempered glass and bottom support bracket and fixedly the groove of piezoelectric ceramics (5) formed, it is characterized in that: floor (1) is structure up and down with bottom support bracket (2), the piezoelectric ceramics groove (5) that piezoelectric ceramics (3) places bottom support bracket to open uses spring (4) to connect for the two four jiaos.
- 2. warning device is laid on a kind of ground according to claim 1, and it is characterized in that: the piezoelectric ceramics upper surface just contacts with the floor.
- 3. warning device is laid on a kind of ground according to claim 1, and it is characterized in that: the piezoelectric ceramics upper and lower surface is connected to lead and forms the loop, and behind the piezoelectric ceramics pressurized, its upper and lower surface produces electric potential difference, produces electric current in the lead alarm bell in the floor is reported to the police.
- 4. warning device is laid on a kind of ground according to claim 1, and it is characterized in that: floor and bottom support bracket are insulating material, and the inner fluting of bottom support bracket is in order to fixing piezoelectric ceramics.
