Abstract

A light-small type fin stabilizer mainly solves the technical problems such as reducing the cabin occupation space, simplifying the structure and improving the reliability, etc, the technic proposal adopted by the utility model is that the light-small type fin stabilizer is provided with a hydraulic unit connected with two actuators respectively by two pipelines and a control valve set. The control valve set is fixedly arranged at a supporting base of the actuators, the utility model is suitable for the boat that the tonnage is not more than 300ton.

Description

Small-sized stabilizer

Technical field:

The utility model relates to a kind of equipment that reduces the motion of rolling ship, particularly a kind of small-sized stabilizer.

Background technology:

Minitype ship (its displacement is not more than 300 tons), as various guard boat, yacht, crew boat etc.,, when these ships and light boats navigate by water, can produce rolling motion in wave, not only influence the navigation performance of ships and light boats, also can worsen the service conditions of personnel on the ships and light boats.For this reason, developed small-sized stabilizer, it can improve the navigability and the traveling comfort of ships and light boats, improve the safety of ships and light boats, promote the overall performance of ships and light boats, the structure of this equipment as shown in Figure 1, include actuating unit 1, accumulation of energy assembly 2, hydraulic pressure unit 3, controller and control box 4, be the equipment of the dynamo-electric combination of a cover, two groups of actuating units 1 are installed in two side of a ship lateral fin seats 51 of hull 5 respectively, stretch in outboard outside two fins 11, actuating unit 1 includes fin 11, fin axle, supporting base, fin handle, reciprocating type commentaries on classics fin oil cylinder and fin angle transmitter etc.; Two hydraulic pressure units 3 symmetry respectively are laid in hull 5 cabins, include electrical motor-oil pump group, by pass valve, valve group, filter, cooling vessel etc., it has fuel feeding, changes fin, changes functions such as fin return-to-zero, locking, and controller and control box 4 include compositions such as programmable controller, signal processing module, gyroscope, voltage transformer and air switch.Also can adopt electro-hydraulic proportional control technology, improve equipment performance.Two hydraulic pressure units of above-mentioned existing small-sized stabilizer, complex structure, it is corresponding, and to occupy volume bigger, bring difficulty than the limited freight space spatial destribution of dinghy for size, the operator is the Operation and Maintenance difficulty in narrow crowded space, and its dynamic movement member is many, easily produce fault, the overall operation cost is higher, and the valve group is located on the hydraulic pressure unit and to be connected in the reciprocating type commentaries on classics fin oil cylinder of actuating unit than long pipe runs, its controller performance is relatively poor.

The utility model content:

Technical problem to be solved in the utility model is, a kind of improved small-sized stabilizer is provided, and its can simplified structure, and it is little to account for the space, cabin, the reliability height, make and use cost low, functional raising.

The technical scheme in the invention for solving the above technical problem is, small-sized stabilizer includes actuating unit, accumulation of energy assembly, hydraulic pressure unit, controller and control box, actuating unit comprise fin respectively the symmetry be installed on the fin seat of hull two topsides, the accumulation of energy assembly is connected between actuating unit and the hydraulic pressure unit, be characterized in that small-sized stabilizer is provided with a hydraulic pressure unit, this hydraulic compressor group is connected in two actuating units through two pipelines and control cock respectively.Two actuating units that drive two topsides with a hydraulic pressure unit under the control of controller rotate the fin axle, reduce the rolling motion that ships and light boats navigate by water in wave effectively.

Hydraulic pressure unit of the utility model mat drives two actuating units, the texture ratio that drives two actuating units with existing two hydraulic pressure units, it accounts for the space, cabin and can reduce more than 20%, and its parts and component number obviously reduce, and especially moving member reduces, simplified structure not only, and can improve the reliability of equipment, and reducing the manufacturing cost and the navigation and handling costs expenditure of equipment, the control cock group is installed on the actuating unit bearing, shorten control oil channel, improve the overall operation function.

Description of drawings:

Fig. 1 is traditional small-sized stabilizer structural representation.

Fig. 2 is the small-sized stabilizer structural representation of the utility model.

Fig. 3 be among Fig. 2 actuating unit structure A to scheme drawing.

Fig. 4 is a hydraulic pressure unit structural representation among Fig. 2.

The specific embodiment:

With reference to Fig. 2, small-sized stabilizer includes larboard actuating unit 1 and starboard actuating unit 1 ', left accumulation of energy assembly 2 and right accumulation of energy assembly 2 ', hydraulic pressure unit 3 and controller and control box 4, left and right side of a ship actuating unit 1,1 ' symmetry are laid in two topside bearings 51 of hull 5, and other compositions are laid in the corresponding cabin or on the deck.

Left and right side of a ship actuating unit 1,1 ' include left and

right sides fin
