Abstract
The invention discloses an underwater detector overpressure alarm device, which solves the problem that an underwater detector alarm device polluted by environment cannot alarm. The underwater detector overpressure alarm device comprises an underwater detector shell body (1), wherein an overpressure alarm installation hole (2) is formed in the underwater detector shell body (1), a piston cylinder body (3) is arranged in the overpressure alarm installation hole (2), a piston (5) is arranged in the piston cylinder body (3), the top end of a piston rod (7) penetrates the piston cylinder body (3) and is connected with a metal communication ball (9), the metal communication ball (9) is arranged just above the middle of a circuit left switching-on plate (11) and a circuit right switching-on plate (12), a positive electrode of a power supply (14) is electrically connected with one end of an underwater sonar instrument (15), and the other end of the underwater sonar instrument (15) is electrically connected with the circuit left switching-on plate (11). The underwater detector overpressure alarm device utilizes the interrelation between water pressure and a spring force, and achieves the overpressure alarming purpose, thereby greatly reducing the product cost.
Description
Technical field
The present invention relates to a kind of warning device, particularly a kind of overpressure alarm device of diving detector.
Background technology
Along with the development of undersea detection technology, the application of underwater detectoscope is more and more extensive, the pressure-bearing of underwater detectoscope has a definite limitation, when detector dive is to the pressure-bearing limit, instrument wherein can be made to be damaged, in the prior art, underwater detectoscope is also provided with overpressure alarm device, this overpressure alarm device generally adopts pressure transducer, because underwater environment is severe, pressure transducer, often by sludge blockage, makes sensor cisco unity malfunction or damage, cause over voltage alarm device can not and alarm.
Summary of the invention
The invention provides a kind of underwater detectoscope overpressure alarm device, solve the problem that undersea detection warning device can not be reported to the police by environmental pollution.
The present invention solves above technical matters by the following technical programs:
A kind of underwater detectoscope overpressure alarm device, comprise underwater detectoscope housing, detector housing is provided with overpressure alarm device mounting hole under water, piston barrel is provided with in overpressure alarm device mounting hole, piston is provided with in piston barrel, O-ring seal is provided with between piston and piston barrel madial wall, stage clip is connected at the upper cover of piston rod be connected with piston, after the top of piston rod passes piston barrel, be connected with metal and be communicated with ball, being communicated with at metal is provided with every electric layer pad between ball and the top of piston rod, the top cover of piston barrel is connected with electrode mounting box, circuit left connection sheet and the right connection sheet of circuit is respectively arranged with in electrode mounting box, be provided with metal directly between circuit left connection sheet with the right connection sheet of circuit and be communicated with ball, the positive pole of power supply and one end of underwater sonar instrument are electrically connected, the other end of underwater sonar instrument and the left connection sheet of circuit are electrically connected, the negative pole of power supply and the right connection sheet of circuit are electrically connected.
Between detector housing and piston barrel, be provided with O-ring seal, the piston barrel end face directly over piston is provided with piston stopper.
The present invention is different from traditional pressure sensor design thinking, but adopt the mutual relationship of water pressure and spring force, achieve the object of over voltage alarm, the overpressure alarm device specific pressure sensor of mechanical structure part is cheaply a lot, thus greatly reduces cost of products; Be specially adapted to use in rugged surroundings under water; There is good environmental suitability, low to requirement for environmental conditions such as temperature, humidity, vibrations.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of underwater detectoscope overpressure alarm device, comprise underwater detectoscope housing 1, under water detector housing 1 is provided with overpressure alarm device mounting hole 2, piston barrel 3 is provided with in overpressure alarm device mounting hole 2, piston 5 is provided with in piston barrel 3, O-ring seal 6 is provided with between piston 5 and piston barrel 3 madial wall, the piston rod 7 be connected with piston 5 is socketed with stage clip 8, after the top of piston rod 7 passes piston barrel 3, be connected with metal and be communicated with ball 9, being communicated with at metal is provided with every electric layer 13 between ball 9 and the top of piston rod 7, the top cover of piston barrel 3 is connected with electrode mounting box 10, circuit left connection sheet 11 and the right connection sheet 12 of circuit is respectively arranged with in electrode mounting box 10, be provided with metal directly between circuit left connection sheet 11 with the right connection sheet 12 of circuit and be communicated with ball 9, the positive pole of power supply 14 and one end of underwater sonar instrument 15 are electrically connected, the other end of underwater sonar instrument 15 and the left connection sheet 11 of circuit are electrically connected, the negative pole of power supply 14 and the right connection sheet 12 of circuit are electrically connected.
