Abstract
The invention discloses a kind of bridge viberation detectors, including battery, shock sensor, resistance, first capacitor, the second capacitor, the first triode, the second triode, control chip and voltmeter, compared with prior art, the present invention is constituted only with several electronic components, finished product it is small in size, it is easy to carry, when detection, it only needs for the device of the invention to be placed in and judges that pointer variation can determine whether the shock conditions of bridge on bridge, judge easy to use, have the value of popularization and application.
Description
Technical field
The present invention relates to a kind of bridge security detection auxiliary device more particularly to a kind of bridge viberation detectors.
Background technique
Bridge refers generally to be erected in rivers,lakes and seas, the structures for making traffic etc. that can smoothly pass through.It is modern to adapt to
The transportation industry of high speed development, bridge be also extended to across mountain stream, unfavorable geology or meet other traffic need and set up make
Current more convenient and fast building.Bridge is generally made of superstructure, substructure, support and attached structure, top knot
Structure is also known as bridge span structure, is across the primary structure of obstacle；Substructure includes abutment, bridge pier and basis；Support is spanning knot
The load transfer device of the bearing place setting of structure and bridge pier or abutment；Attached structure then refer to transition slab at bridge head, truncated cone banking, shore protection,
Training works etc..In the prior art, crackle etc. is generally only checked for the safety check of bridge, but in the longer situation of bridge, vibration
It is larger, need to judge whether the shockproofness of bridge is too strong, thus judge the bearing capacity etc. of bridge, prior art judgement vibration
Intensity is not convenient enough, and accordingly, there exist rooms for improvement.

Two pins are connect with the second end of the second capacitor, and the 4th pin for controlling chip is connect with the base stage of the second triode, and the two or three
The collector of pole pipe and the second end of voltmeter connect.
Circuit of the present invention uses vibrating sensing device, is placed on bridge, and vehicle can shake when passing through on bridge, vibration
Dynamic sensor has the base stage that signal is sent to the first triode VT1, is added to the signal of amplification after the first triode VT1 amplification
The first pin for controlling chip IC, is exported after control chip IC processing by the 4th pin, removes driving electricity through the second triode VT2
Table is pressed to show voltage, when vibration degree is bigger, output voltage is bigger, observes the variation of voltmeter and judges the vibration journey of bridge
Degree.
Basic principles and main features and advantages of the present invention of the invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
