Description
Technical field
The present invention relates to the field of fishing for waterborne, relate in particular to trawlboat.
Background technology
Trawlboat is with trawlnet, to fish for the boats and ships of fish.Trawlnet in trawlboat is to utilize the guiding principle winch that drags on deck to receive net.Dragging a net in fishing is a kind of fishing method effective, applied widely.Trawlboat is also a kind of fishing boat that quantity is maximum.
A kind of common trawlboat trawlnet mounting structure, in hull line of centers arranged on left and right sides, arrange that is respectively draged a guiding principle winch, guiding principle is draged in one of the configuration respectively of draging on guiding principle winch, drag guiding principle free end and be parallel to mind-set stern stretching in hull, after drawing in gradually after angle pulley commutation through being fixed on stern, be separately fixed at the trawlnet both sides in waters, stern rear.
During fishing, fishing boat drives trawlnet to move ahead by draging guiding principle, in traveling process, the various fish in trawlnet the place ahead will enter from the opening of trawlnet front end trawlnet inside and be collected, and advance after a segment distance, drag guiding principle winch and pack up and drag guiding principle, trawlnet is packed up, just can have been collected the fish in trawlnet.
In the process of fishing, the attitude of net type plays vital impact to fishing efficiency, desirable net type should fullly open, be conducive to the shoal of fish and enter network interface and fugacity not, on the contrary, if the flat flat distortion of net type, network interface is narrow, not only bad for the shoal of fish that catches network interface the place ahead, and the shoal of fish that enters trawlnet is easy to escape from net, greatly impact fishing efficiency.
The net type of trawlnet is mainly that left and right two by its both sides of dehiscing drag guiding principle and control, if left and right two length of draging guiding principle are consistent, trawlnet will naturally open under the power of doing of water body resistance, but because sea situation in the process of fishing for is complicated, the fluctuating of wave can cause the heave movement of hull, thereby cause left and rightly draging that guiding principle is different in size to be caused, causing two, to drag the tension force of guiding principle different, make trawlnet net type variation.
Current drag guiding principle equalization of strain compensation master and by operation, drag guiding principle winch to tighten up/loosen and drag guiding principle, thereby guarantee that waving middle left and right drags guiding principle equalization of strain, but this compensating chain device need to start winch motor frequently, and the fluctuating along with hull, otherwise stop changing the rotation direction of motor, very large to the loss of motor, greatly shortened service life of motor.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of equalization of strain compensation configuration structure, this structure can be when trawling process, can be according to hull heave movement, automatically regulate and drag guiding principle length, to guarantee to drag guiding principle tension stability, thereby reach the object of controlling net type, and in adjustment process, do not need to start winch motor.
The present invention is achieved by the following technical solutions:
A kind of guiding principle equalization of strain that drags of trawlboat compensates configuration structure, in the hull line of centers arranged on left and right sides of trawlboat, arrange that is respectively draged a guiding principle winch, guiding principle is draged in one of the configuration respectively of draging on guiding principle winch, draging guiding principle free end is parallel to hull line of centers and stretches to stern, after drawing in gradually after angle pulley commutation through being fixed on stern, the trawlnet both sides that are separately fixed at waters, stern rear, is characterized in that:
In every portion, drag draging above guiding principle between guiding principle winch and angle pulley, arrange respectively a power leading sheave group, power leading sheave group comprises three pulleys that are " product " distribution, and three pulleys all can be around self line of centers rotation, its rotation centerline is with to drag guiding principle length direction vertical
In power leading sheave group, first, second pulley that is positioned at both sides is fixed on hull, and the 3rd middle pulley below configures respectively a hydraulic ram, and the 3rd pulley is arranged on the piston rod upper end of hydraulic ram,
Drag guiding principle and take up in corresponding power leading sheave group, drag guiding principle and upwards walk around in turn the lower edge of the first pulley, the upper limb of the 3rd pulley, then walk around the lower edge of the second pulley downwards,
Hydraulic ram is fixed on hull, and piston is divided into upper and lower two chambers of mutually isolating by cylinder cavity, and its upper chamber is connected with fuel tank, and lower chambers connects fuel tank by the first normally closed valve,
Energy storage Wei Yi sealed chamber, configures a piston in chamber, chamber is divided into oil pocket and the air cavity of mutual isolation, is full of pressurized air in air cavity, and oil pocket is connected with the lower chambers of hydraulic ram,
Described configuration structure comprises four kinds of configuration operating modes:
1. when trawlboat rocks back and forth, if hull phase pair trawling upward movement left and rightly drags guiding principle to oppress respectively the piston rod of hydraulic ram descending, hydraulic oil enters energy storage, and the air pressure of energy storage compressed air raises, energy storage stored energy;
2. when trawlboat rocks back and forth, if hull phase pair trawling moves downward, the left and right guiding principle pressure decreased that drags that hydraulic cylinder piston rod is subject to, the energy that energy storage compressed air stores discharges, hydraulic oil is entered the lower chambers of hydraulic ram by energy storage, piston rod is up, upwards supports and drags guiding principle, makes to drag guiding principle tensioning;
3. when trawlboat swings, if hull left side phase pair trawling moves downward, right side phase pair trawling upward movement, rightly drags guiding principle to oppress the piston rod of right hydraulic ram descending, and the hydraulic oil of right hydraulic ram flows out; Meanwhile, guiding principle pressure decreased is draged on the left side that left hydraulic cylinder piston rod is subject to, and hydraulic oil enters left hydraulic ram;
In this process, if the amplitude that hull left side declines is greater than the amplitude rising on right side, energy storage releases energy, and the hydraulic oil in energy storage enters left hydraulic ram;
If the amplitude rising on hull right side is greater than the amplitude that left side declines, hydraulic oil enters energy storage, energy storage stored energy;
If the heave amplitude of hull both sides is suitable, hydraulic oil only flows between left hydraulic ram and right hydraulic ram;
4. when trawlboat swings, if hull right side phase pair trawling moves downward, left side phase pair trawling upward movement, leftly drags guiding principle to oppress the piston rod of left hydraulic ram descending, and the hydraulic oil of left hydraulic ram flows out; Meanwhile, guiding principle pressure decreased is draged on the right side that right hydraulic cylinder piston rod is subject to, and hydraulic oil enters right hydraulic ram;
In this process, if the amplitude that hull right side declines is greater than the amplitude rising in left side, energy storage releases energy, and the hydraulic oil in energy storage enters right hydraulic ram;
If the amplitude rising in hull left side is greater than the amplitude that right side declines, hydraulic oil enters energy storage, energy storage stored energy;
If the heave amplitude of hull both sides is suitable, hydraulic oil only flows between left hydraulic ram and right hydraulic ram.
The principle of work of this configuration structure is: when hull is subject to wave, affect swing, original length is consistent, it is inconsistent in balance position left and right, to drag the guiding principle tightness that becomes, the dehisce stressed not phase time of both sides of trawlnet, utilization is taken up and is supported and loose drag guiding principle, unclamp the guiding principle that drags of tensioning draging power leading sheave group on guiding principle, the tightness of guiding principle is draged in compensation, the tensile force that both sides are draged on guiding principle is consistent, with balance trawlnet the stressed of both sides of dehiscing, thereby reaches the object of adjusting net type.
Power leading sheave group supports/unclamps drags guiding principle and drives by hydraulic circuit, when draging guiding principle tensioning, the piston rod retract cylinder that pulley is stressed, force hydraulic ram, hydraulic ram exudate force feed, flow into energy storage, this part stored energy is got up, when draging guiding principle when loose, the downward pressure that hydraulic cylinder piston rod is subject to reduces, piston rod stretches out, and energy storage promotes hydraulic oil and gets back in hydraulic ram, completes the release of energy.
In energy storage the storage of energy and release be by its air cavity compressed air volume reduce/increase realize, can make full use of like this propulsive effort that is used as mechanism by this natural force of the heave of waves, energy consumption is low.
The first normally closed valve is generally opened before passive compensating movement starts, and is to be mainly hydraulic ram fuel feeding or new and old oil, closes this valve during fishing.
Further, consider the finite volume of air cavity, limited to draging the compensation of guiding principle equalization of strain in the area of sea situation acute variation, therefore sea situation that can be regional according to compensation, and the variation of balancing force, give air cavity configuration gas cylinder group, supercharging air pump and the source of the gas of energy storage, to meet under different work condition, the variation requirement of trawlnet tension force.The air cavity of energy storage is connected with the gas cylinder group being comprised of a plurality of pressurized air gas cylinders arranged side by side by the second valve of often opening, and the air cavity of energy storage is communicated with supercharging air pump and source of the gas in turn by the second valve.Before fishing, first utilize source of the gas, supercharging air pump for being filled with the pressurized air of setting pressure in gas cylinder group and energy storage, make left and right two to drag guiding principle length when consistent, equalization of strain, the state of whole hydraulic circuit in initial balance.
Further again, can be between power leading sheave group and angle pulley, near the assembly of power leading sheave, put a directional wheel, the rotation centerline of directional wheel, with to drag guiding principle length direction vertical, drag guiding principle and walks around and compress directional wheel upper limb from directional wheel upper limb.Directional wheel mainly plays positioning action to draging guiding principle, prevents from draging guiding principle and beats in power leading sheave group.
Further again, hydraulic ram is connected with energy storage by the 3rd valve of often opening, and offers along its length microscler piston position observation window on hydraulic ram.When observe the work area of piston in hydraulic ram from form, depart from oil cylinder middle part, during near oil cylinder top or bottom, show that now the work area of piston is unsatisfactory, now can close the 3rd valve, close the passive compensate function of hydraulic ram, to regulate the work area of oil cylinder, it is returned near oil cylinder center, after adjusting, open again the second valve, open the passive compensate function of hydraulic ram.
Further again, drag guiding principle after walking around the first pulley lower edge, walk around straight up the 3rd pulley upper limb, then walk around vertically downward the lower edge of the second pulley.Thereby guarantee that the guiding principle pressure that drags that the 3rd pulley is subject to is vertically downward, rather than two pressure symmetrically, under being tilted to, what hydraulic cylinder piston rod was subject to is to drag the total power of guiding principle rather than component, the reaction of whole hydraulic circuit is sensitiveer.
Further again, the oil pocket of energy storage is communicated with fuel tank by ball relief valve group.When energy storage stored energy is too high, discharge hydraulic oil oil sump tank, guarantee security of system.
Beneficial effect of the present invention is:
1, by pressurized air, absorbed, stored the impact of hull sink-float pair trawling, and discharge when needed to keep the net type of trawlnet, not only energy consumption is low, and clean environment firendly;
2, compensation process does not need human intervention, and mechanism is to draging the adjusting intuitive and convenient of guiding principle tension force, and setting range is wide;
3, with other similar elastic compensating configuration structure, as spring etc., to compare, the volume of hydraulic gear is little, is beneficial to layout;
4, do not need to start frequently winch motor, adjust the rotation direction of winch motor and carry out two tension force that drag guiding principle of balance, extended the service life of winch motor.
