Abstract
The utility model provides an insulation propeller support installed on a scale model. The insulation propeller support comprises two fixing nuts, connecting screw rods, connecting rotary heads and transverse screw rod shafts, wherein the two fixing nuts are oppositely connected to the bottom of the ship scale model, the connecting screw rods are connected into the fixing nuts respectively, the connecting rotary heads are installed on the two connecting screw rods respectively, and the transverse screw rod shafts are installed in the two connecting rotary heads in a sleeved mode respectively. The opposite ends of the two screw rod shafts are provided with threads used for installing a scale propeller, and fastening nuts used for fastening the scale propeller. According to the insulation propeller support, the scale propeller model can be stabilized and fixed according to the actual position where a propeller of an actual ship is located; moreover, all parts are made of insulating materials, in an experiment, the propeller and a ship hull are not communicated so that the experimental structure of the scale model can conform to the actual situation better, and measurement accuracy of experimental data can be effectively improved.
Description
Technical field
The utility model relates to propeller bracket, relates in particular to be a kind ofly arranged on the insulation propeller bracket on scale model for marine corrosion monitoring test.Belong to Naval Architecture and Ocean Engineering field.
Background technology
At present, in the middle of the enterprising oceangoing ship corrosion monitoring test of navigating of scale model, the propeller bracket of its scale model, adopts the structure identical with entity ship mostly, and drives screw propeller rotation by DC machine.Due on entity ship, screw propeller can produce certain impact to the surface potential of hull bottom; And because existing scale model propeller bracket all adopts uninsulated metal material, therefore, in the middle of marine corrosion monitoring scale model test, must consider the impact of propeller on entity ship; Simultaneously, again due in the middle of scale model test, the model component size adopting is generally much smaller compared with entity ship, if according to the propeller supporting structure form of entity ship, process the support in scale model test, do so not only complex process, and, in hydrostatic, in test, be also not easy to control.
Utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of improved insulation propeller bracket being arranged on scale model, it not only can be according to the actual position at entity ship screw propeller place, screw propeller scale model is stablized fixing, and, because all parts all adopt insulation material, in experiment, screw propeller and hull are in not on-state, scale model test structure is tallied with the actual situation more, effectively improve the accuracy that test figures is measured.
The purpose of this utility model is realized by following technical scheme:
A kind of insulation propeller bracket being arranged on scale model, it is characterized in that: comprising: be relatively connected to boats and ships scale model bottom two captive nuts, be connected to connecting screw rod in captive nut, be arranged on connection rotary head on two connecting screw rods respectively, be set in the transverse screw axle in two connection rotary heads, wherein, the end that two screw rods axle is relative be provided with for install contracting than the screw thread of screw propeller, and for fastening contracting than the clamp nut of screw propeller.
The described connection rotary head being arranged on two connecting screw rods is to adopt flush fit mode.
Described captive nut, connecting screw rod, screw shaft, connection rotary head, clamp nut all adopt insulation material.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, it not only can be according to the actual position at entity ship screw propeller place, screw propeller scale model is stablized fixing, and, because all parts all adopt insulation material, in experiment, screw propeller and hull are in not on-state, scale model test structure is tallied with the actual situation more, effectively improve the accuracy that test figures is measured.
Brief description of the drawings
Fig. 1 is that the utility model structure master looks schematic diagram.
Fig. 2 is the utility model schematic side view.
Major label description in figure:
Hull, 2. captive nut, 3. connecting screw rod, 4. screw shaft, 5. connect rotary head, 6. clamp nut, 7. screw propeller is compared in contracting.
Detailed description of the invention
As shown in Fig. 1-Fig. 2, the utility model comprises: adopt welding manner be relatively connected to boats and ships scale model 1 bottom two captive nuts 2, be connected to connecting screw rod 3 in captive nut 2, adopt flush fit mode to be arranged on respectively connection rotary head 5 on two connecting screw rods 3, to be set in the transverse screw axle 4 in two connection rotary heads 5, wherein, the end that two screw rods axle 4 is relative be provided with for install contracting than the screw thread of screw propeller 7, and for fastening contracting than the clamp nut of screw propeller 76.
Above-mentioned captive nut 2, connecting screw rod 3, screw shaft 4, connect rotary head 5, clamp nut 6 and all adopts as the insulation material of rubber, plastics.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
