Background technique

In reality, since the tonnage of fishing boat is smaller, it is affected when carrying out long range fishing by stormy waves, especially cantilever crane Formula fishing boat, since the trawlnet cantilever crane being arranged in Ship Structure is generally longer, in trawling, cantilever crane is in horizontality, There are many free end stretching Ship Structure of cantilever crane, and the drag force by fishing net, since one end of cantilever crane is hinged on Ship Structure On, free end does not have support construction, therefore the outer end of cantilever crane is easy stress and is damaged, and even resulting in fishing boat turns on one's side, Jeopardize the life security of crewman.

Summary of the invention

The purpose of the present invention is there is the above problem in view of the prior art, a kind of support for trawlnet cantilever crane is proposed Structure, the present invention are provided a supporting role in trawlnet cantilever crane operation, guarantee the stability of trawlnet cantilever crane and the operation safety of fishing boat.

Object of the invention can be realized by the following technical scheme: a kind of support construction for trawlnet cantilever crane, including The free end of frame body, the frame body is equipped with support construction, and the support construction includes supporting case and buoyancy body, the supporting case The top of frame body is set, battery is equipped in the supporting case, the downside of the supporting case is equipped with hydraulic elevating platform, institute The lower end for stating hydraulic elevating platform is equipped with lifter plate, and the surrounding of the buoyancy body upper side is equipped with piston cylinder, the piston cylinder Including cylinder body and piston rod, the bottom of the cylinder body is hinged on the upper side of buoyancy body, and the lower end of the piston rod is equipped with piston, The piston is slidably arranged in cylinder body, and the upper end of the piston rod is hinged on the downside of lifter plate, and the piston is by cylinder Internal body portion is epicoele and cavity of resorption, and water inlet pipe and upper water-out pipe are connected at the top of the epicoele, and the bottom of the cavity of resorption connects It is connected to lower water inlet pipe and lower discharging tube, the frame body is equipped with water tank, is equipped in the water tank and utilizes the water in water tank The power generator to generate electricity, the upper water-out pipe and lower discharging tube are all connected to water tank, offer in the buoyancy body logical Kong Yi, the upper end outlet of the through-hole one are located at the upper side of buoyancy body, and the lower end outlet of the through-hole one is located at buoyancy body Bottom, the upper water inlet pipe and lower water inlet pipe are all connect with the upper end of through-hole one, the upper water inlet pipe, upper water-out pipe, lower water inlet Check valve is equipped at the port of pipe and lower discharging tube.

When fishing boat carries out trawling, frame body is in horizontality, starts hydraulic elevating platform, and lifter plate is transported downwards It is dynamic, so that buoyancy body bottom is completely attached to the water surface, buoyancy of the buoyancy body by seawater provides a upward support force to frame body, Since marine stormy waves is larger, the position of buoyancy body constantly changes, the work when buoyancy body is mobile to wave crest from trough, by wave When with moving upwards, buoyancy body and cylinder body are moved up, and piston is moved downward relative to cylinder body, under intracavitary water be extruded, from Lower discharging tube flows into water tank, upper intracavitary formation negative pressure, and seawater flows into from through-hole one by enterprising water pipe upper intracavitary；Work as buoyancy body From wave crest to trough it is mobile when, buoyancy body moves down under self gravitation effect close to the water surface, and cylinder body is also and then to moving down Dynamic, piston is moved upwards relative to cylinder body, and upper intracavitary water is extruded, and flows into water tank from upper water-out pipe, under it is intracavitary formed it is negative Pressure, seawater, by intracavitary under the inflow of lower water inlet pipe, are to counteract the impact of seawater, and make hydraulic lifting flat from through-hole one in this way Platform keeps relative stability, while guaranteeing that buoyancy body contacts the water surface always, obtains the buoyancy of seawater again, provides to the free end of frame body Support, improves the stability of ship；Further, since the setting of check valve be so that upper water inlet pipe and lower water inlet pipe can only intake, on Outlet pipe and lower discharging tube can only be discharged, and prevented the cisco unity malfunction that causes confusion inside piston cylinder, lost buffer function.

In the above-mentioned support construction for trawlnet cantilever crane, the bottom of the water tank offers discharge orifice, the flowing water The lower end in hole is equipped with electrically-controlled valve, is equipped with liquidometer in the water tank, the liquidometer is by being electrically connected with controller, the control Device processed is electrically connected with electrically-controlled valve, is provided with water flow generator, the input shaft of the water flow generator by branch in the discharge orifice End be equipped with impeller two, the impeller two is coaxially disposed with discharge orifice, and the water flow generator is electrically connected with battery.

The intracorporal water of cylinder is flowed into water tank by upper water-out pipe and lower discharging tube, and electrically-controlled valve, which is in, at this time closes shape State, when the water level in water tank reaches specified altitude assignment, liquidometer sends a signal to controller, and controller issues instructions to automatically controlled Valve, opens electrically-controlled valve, and the water accumulated in water tank is discharged from discharge orifice；When the water in water tank reaches lowest water level, liquid level Meter sends a signal to controller, and controller issues instructions to electrically-controlled valve, closes electrically-controlled valve, and water is waited to accumulate to specified water level, from The water impeller two that discharge orifice excludes rotates, and so that water flow generator is generated electricity, is then stored in battery, utilizes the gravity of water Potential energy power generation, it is environmentally protective.
