Description
Mooring ship Impact energy sensor is mainly used in the oceanographic engineering mooring ship model test, belongs to ocean engineering model test field.
Oceanographic engineering mooring ship model test arises from 1974 at first in China.China began to build first 100,000 tons of crude exports harbour in 1973, and this engineering design is born by Dalian University of Technology, and the model test of relevant this project is also born by Dalian University of Technology.This kind model test also is to carry out first at home, need carry out the test of mooring ship Impact energy in model test.Owing to do not have ready-made available sensor, made dynamometry by oneself and surveyed the displacement device sensor.
Existing dynamometry is surveyed the displacement device sensor and is made up of rubber bodies, counter-force meter and extensometer three parts.Ship bump rubber bodies, rubber bodies pass to power on the counter-force meter and self compression deformation take place simultaneously, drive extensometer during distortion, can calculate Impact energy according to the synchro measure result of counter-force meter and extensometer.Because a cantilever phosphorus bronze sheet is counted in displacement, its existence influences the distortion of fender itself, causes the flexible increase of fender, causes test findings to produce deviation; The cantilever phosphorus bronze sheet of extensometer, lower end are propped up on the fender top board, under the external force effect of boats and ships, eject sometimes, cause test failure; Dynamometer, extensometer are cantilever beam structure, and the resistance wire sheet of subsides is all exposed outside, is easily damaged; The split structure is counted in dynamometer, displacement, before each test, must assemble, and demarcate respectively, spends the more time.
The purpose of this utility model provides the mooring ship Impact energy sensor of a kind of one fast and accurate measurement, device security work.
Principle of work of the present utility model is the variable element sensor, sensor dynamometry sheet changes with cantilever beam structure, resistance parameter, surveying displacement is the slidingtype hanging deck with capacitance parameter variation, its structure, do not influence the distortion of fender when surveying displacement, dynamometry, survey displacement are combined into one, be convenient to install, measure concentrated being placed in the box of used electric elements and do not expose outside, should not damage.
The test boats and ships under external force, ship collision arrives, make and survey deformed plate (3) slip, make quoit (5) in the box body (10), the electric capacity that quoit (12) and quoit (15) constitute changes, when impact block (2) moves, model fender (1) is compressed, its counter-force affacts force plate (4), cause the sensing chip (7) in the box body (10), sensing chip (8), the resistance of sensing chip (13) and sensing chip (14) changes, so just, be separately converted to the signal of two electricity, according to prior demarcation with model fender (1) distortion and power under external force, but synchronometer is calculated the size of distortion and power, thereby calculates Impact energy.Two signals of DATA REASONING treating apparatus (16) record, one is impact, one is the distortion of fender, and requires synchronous recording, when distortion reaches maximum, pairing power, measured, according to the relation of power and distortion, calculate energy then, i.e. energy E=1/2h*f.
Technical solution of the present utility model is, mooring ship Impact energy sensor comprises model fender (1), impact block (2), survey deformed plate (3), force plate (4), fixed head (6), sensing chip (7), sensing chip (8), sensing chip (13) and sensing chip (14), model fender (1) one end is connected with force plate (4), the other end is connected with survey deformed plate (3), impact block (2) is fixed on to be surveyed on the deformed plate (3), sensing chip (7) and following being connected of sensing chip (14) with force plate (4), sensing chip (8) and top being connected of sensing chip (13) with force plate (4), it special, also comprise quoit (5), fixed head (9), box body (10), rod (11), quoit (12), quoit (15) and DATA REASONING treating apparatus (16), to pass and be fixed on the quoit of surveying on the deformed plate (3) (5), the rod that is with quoit (15) (11) of quoit (12) is fixed on the fixed head (9), fixed head (9) is fixedlyed connected with box body (10), quoit (5), quoit (12) is connected with DATA REASONING treating apparatus (16) with the electric capacity that quoit (15) constitutes, sensing chip (7), sensing chip (8), sensing chip (13) connects into Wheatstone bridge with sensing chip (14) and is connected with DATA REASONING treating apparatus (16), and the other end of force plate (4) is connected with box body (10).
Quoit (5) and quoit (12) link together from the upper and lower hole of surveying deformed plate (3) of passing, and are fixed on the survey deformed plate (3).
Quoit (15) is embedded on the rod (11).
The utility model has the advantages that surveying the displacement plate is to adopt movable pattern, has avoided in test process the flexible influence of fender; Electric elements are concentrated and are contained in the box, have played protective effect, have prolonged the serviceable life of instrument; Overall construction design is reasonable, is applicable to all kinds of rubber fenders, is convenient to change.Because this sensor is an integral body, simple installation.After using this measuring method, can increase work efficiency greatly, guarantee test accuracy simultaneously
