Description
Technical field
The present invention relates to a kind of warning device, in particular to the overpressure alarm device of a kind of diving detector.
Background technology
Along with the development of underwater exploration technology, the application of asdic is more and more extensive, the pressure-bearing of asdic 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, asdic is also provided with overpressure alarm device, this kind of overpressure alarm device generally adopts pressure transmitter, owing to environment is severe under water, pressure transmitter often by sludge blockage, make sensor can not normal operation or damage, cause over voltage alarm device not report to the police in time.
Summary of the invention
The present invention provides a kind of asdic overpressure alarm device, solves the problem that underwater exploration warning device can not be reported to the police by environmental pollution.
The present invention solves above technical problem by the following technical programs:
A kind of asdic overpressure alarm device, comprise asdic housing, asdic housing is provided with overpressure alarm device open holes, overpressure alarm device open holes is provided with piston barrel, piston barrel is provided with piston, it is provided with sealing-ring between piston and piston barrel inner side-wall, it is connected to stage clip at the upper cover of piston rod being connected with piston, after the top of piston rod passes piston barrel, it is connected with metal and it is connected ball, it is connected at metal and it 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 box is installed, install in box at electrode and it is respectively arranged with circuit left connection sheet and the right connection sheet of circuit, surface between circuit left connection sheet connection sheet right with circuit is provided with metal and is connected 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, it is provided with sealing-ring, the piston barrel end face directly over piston is provided with piston back-up ring.
The present invention is different from traditional pressure sensor design thinking, but adopt the mutual relationship of water pressure and spring power, achieving the object of over voltage alarm, the overpressure alarm device of mechanical structure part is much more cheap than pressure transmitter, thus greatly reduces product cost; It is specially adapted in severe environment under water and uses; There is good environmental compatibility, the envrionment conditionss such as temperature, humidity, vibration are required low.

Fig. 1 is the structural representation of the present invention;
Fig. 2 is the shape assumption diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of asdic overpressure alarm device, comprise asdic housing 1, asdic housing 1 is provided with overpressure alarm device open holes 2, overpressure alarm device open holes 2 is provided with piston barrel 3, piston barrel 3 is provided with piston 5, it is provided with sealing-ring 6 between piston 5 and piston barrel 3 inner side-wall, the piston rod 7 being connected with piston 5 is socketed with stage clip 8, after the top of piston rod 7 passes piston barrel 3, it is connected with metal and it is connected ball 9, it is connected at metal and it 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 box 10 is installed, install in box 10 at electrode and it is respectively arranged with circuit left connection sheet 11 and the right connection sheet 12 of circuit, surface between circuit left connection sheet 11 connection sheet 12 right with circuit is provided with metal and is connected 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.
Between detector housing 1 and piston barrel 3, it is provided with sealing-ring 16, piston barrel 3 end face directly over piston 5 is provided with piston back-up ring 4.
The working process of the present invention is as follows: according to the requirement of instrument pressure-bearing in asdic, the precompressed elastic force of design stage clip 8, and stage clip 8 is arranged in piston barrel 3, asdic is put into water, when dive exceedes the precompressed elastic force of spring 8 to hydraulic pressure, piston 5, under the effect of water pressure, moves down along piston barrel 3, metal is connected ball 9 and sinks to connecting circuit left connection sheet 11 and the right connection sheet 12 of circuit, and underwater sonar instrument 15 starts to report to the police. Operator operate asdic and rise, when rising to hydraulic pressure lower than the precompressed elastic force of spring 8, piston 5 is under the elastic force effect of stage clip 8, move up along piston barrel 3, metal is connected ball 9 and lifts cut-out circuit left connection sheet 11 and the right connection sheet 12 of circuit, underwater sonar instrument 15 stop alarm, and asdic continues to rise, when the elastic force of spring 8 exceedes water pressure, owing to the stop of piston back-up ring 4 makes piston 5 can not depart from piston barrel 3. The present invention according to the bearing capacity of the instrument of different asdics, can change different stage clips 8, can realize the warning of the different dive degree of depth. It is convenient to change, and maintenance is easily.
