Description
Technical field
The present invention relates to marine fishing operation technique field, specifically be meant a kind of two boat trawler towing tension bascule.
Background technology
Two boat trawler is that the both sides of fishing net are held by two ships respectively when operation, and net vertically sinks to the seabed, and the ship on both sides fishing net in tow moves ahead, and forms the net of an arc, as a sack, the thing that head-on comes is bottled up.During operation, very important to the cooperation of fishing net both sides towing tension, if towing tension disequilibrium then can produce sideslip, run oblique phenomenon.Present two boat trawler more options are a conduct ship wherein; The captain is positioned on the ship; Rely on captain's experience to reach control through the adjustment engine speed to two ship towing tensions through range estimation commander two ships; Adopt this Artificial Control mode that captain's experience has been proposed very high requirement; But can reach balance because the limitation of range estimation causes sometimes needs repeatedly to be adjusted, this mode of operation can not adapt to the modern marine trawling when wasting a large amount of fuel.
A kind of fishing boat towing tension display unit is disclosed in the application documents of the patent No.: ZL201020162004.7; This display unit is characterised in that the pulling force display is provided with bolt be connected monitor body and lid; The inner chamber that body and lid form is provided with the distortion dynamometer spring; The through hole of thrust axis on lid is connected with the distortion dynamometer spring; One end of thrust axis is provided with the pulling force hanger; The other end of thrust axis matches with dynamometer link; Dynamometer link is connected with intrinsic pulling force display instrument, and the end of body is provided with the pulling force hanger.This application file points out that further the pulling force display instrument is made up of pulling force sensor and Displaying Meter simultaneously.This fishing boat towing tension display unit adopts the mode of digital measurement that the fishing boat towing tension is shown, has broken away from the defective that relies on artificial experience that towing tension is judged.But there is following limitation in this display unit: 1, adopt the distortion dynamometer spring in the chamber body, we know that spring can produce mechanical fatigue, the measurement meeting great errors of logarithm value after repeatedly pulling; 2, the sensor in the pulling force display instrument adopts pulling force sensor; Pulling force sensor based on principle be that elastomer produces strain under external force; Make the resistance strain gage that sticks on its surface also in company with producing distortion; After the resistance strain gage distortion; Its resistance will change; Through corresponding measuring circuit this resistance variations is converted into the signal of telecommunication again, thereby accomplished the process that external force is transformed to the signal of telecommunication.The advantage of pulling force sensor is that precision is high, but shortcoming is a little less than having bigger non-linear, output signal for big strain, so it is widely used in test automatically and the control technology.But the towing tension amplitude of variation of trawler is very big, adopt pulling force sensor for this significantly towing tension abrupt change meeting produce very big non-linear, cause show the inaccurate of towing tension; 3, the environment of sea fishery operation is very abominable, and display and chest expander body are made as one, is difficult to the display interior circuit is effectively protected, and with the erosion of seawater, sea wind, display is easy to be damaged.If adopt data wire to be connected with pulling force sensor and Displaying Meter is placed in the driving cabin and since pulling force sensor output signal itself just a little less than, through the bigger decay of meeting generation after the transmission of data wire, cause the deficiency of Displaying Meter input signal.Though the measure of in sensor, adopting circuit to compensate is arranged now, can receive the influence of abominable operating environment equally and can not get effective protection if compensating circuit is put into front end.
Summary of the invention
The purpose of this invention is to provide a kind of two boat trawler towing tension bascule, control the technical problem that existing measurement effect is poor, measurement mechanism is difficult for protection to overcome present fishing boat towing tension.
The technical scheme that the present invention adopts is: two boat trawler towing tension bascule; This device contains the towing tension transfer device; Pressure transmitter; The towing tension display instrument; It is characterized in that: described towing tension transfer device comprises a hydraulic cylinder; One pressure transfer tube; Described hydraulic cylinder two ends are respectively equipped with hanger; Wherein a hanger links to each other with hydraulic cylinder cylinder barrel bottom; Another hanger links to each other with the piston rod of hydraulic cylinder; The cylinder cap that piston rod one end passes hydraulic cylinder is connected with hanger; The other end is connected with the inner piston of hydraulic cylinder; Between piston and cylinder cap, form hydraulic fluid chamber, be full of hydraulic oil in the hydraulic fluid chamber; Described pressure transfer tube one end passes the hydraulic cylinder cylinder barrel hydraulic fluid chamber inner with it and connects, and the other end is connected with pressure transmitter; Pressure transmitter output wire size is delivered to the towing tension display instrument and is carried out the towing tension demonstration.
Described towing tension display instrument, it also possesses the wireless transmission function, when data-signal is shown, this signal is modulated and is sent.
Two fishing boats are when operation; For on a fishing boat, clearly obtaining the towing tension size of two fishing boats; Described two boat trawler towing tension bascule comprises that also data receive display, and this display can receive the wireless data signal that the towing tension display instrument sends and show.
When using this two boat trawler towing tension bascule; Pressure transmitter, towing tension display instrument can be placed driving cabin; Can effectively protect electronic component wherein; Need not to increase safeguard procedures especially; Its towing tension transfer device can be delivered to towing tension real-time and accurately pressure transmitter and carry out the signal conversion, and pressure transfer tube length does not have influence basically to the transmission of towing tension.Because pressure transmitter mainly is the signal of telecommunication that physical pressure parameters such as the gas that will receive, liquid are transformed into standard; It has high accuracy, high stability; Volume is little, in light weight; Adopt the stainless steel totally enclosed frame; The advantage that waterproof is good; Therefore the cooperation between the said apparatus can show the fishing boat towing tension accurately in real time, has thoroughly overcome poor accuracy, difficult technical problem of protecting that present measurement mechanism exists.This two boat trawler towing tension balance device structure is reasonable, makes, extremely easy to use, not fragile, can adapt to the adverse circumstances of fishery operation.
