Abstract
The utility model provides a regulation fixing device of a propeller conduit, and belongs to the field of marine machinery. The regulation fixing device comprises a fixed base, a front connection frame, a rear connection frame, a sensor, a connection sword-like component and a conduit, wherein the fixed base is provided with the front connection frame through bolts, the rear connection frame is installed on the front connection frame through bolts, the lower end of the rear connection frame is connected with the sensor through a bolt, the connection sword-like component is installed on the lower end of the sensor, and the connection sword-like component and the conduit are fixed together. The conduit is made of stainless steel materials, and six long-round-shaped fixing holes are formed in the front connection frame. By means of the regulation fixing device, the upper position, the lower position, the left position, the right position and the longitudinal inclined angle of the conduit can be accurately regulated, firm positioning of the conduit can be ensured, and correctness and efficiency of experimental results are ensured. Meanwhile, the regulation fixing device is simple in structure, convenient to process, and suitable for various conduit propeller molds.
Description
Technical field
The utility model relates to a kind of regulation fixing apparatus of propeller nozzle, concrete is a kind of in the spacious water experiment of shrouded propeller model the regulation fixing apparatus of conduit, belong to the ship machinery field.
Background technology
Because trawlboat is the boats and ships that propeller load is large, working conditions change is many, the road-holding property requirement is higher, two kinds of operating modes of free running and trawlnet navigation are arranged, its requirement has the higher speed of a ship or plane when free running, and larger towing tension is arranged when trawlnet navigates by water.So, if trawlboat adopts shrouded propeller as propelling unit, namely behind the peripheral installation of screw propeller mozzle, can change screw propeller streamflow regime on every side, thereby improve its serviceability, increase towing tension, improve propulsion coefficient, save energy consumption.
Interaction between screw propeller and the current is continuous variation, after adopting shrouded propeller, make this interaction more complicated, be difficult to obtain the result who gears to actual circumstances with the method that pure theory is calculated, so, shrouded propeller model open water experiment is check and the comparatively easy mode of hydrodynamic performance of analyzing shrouded propeller, is about to the shrouded propeller model and tests in the uniform flow individually.
Shrouded propeller is opening water when experiment, the position adjustment of conduit and fixing be a difficult problem always.Usually the distance of fixed position point is too large, cantilever is oversize, causes the unstable of catheter position because conduit arrives; Also can cause the vibration of model axle system when shrouded propeller rotates at a relatively high speed simultaneously.The consequence of bringing thus is serious, and the lighter has destroyed similarity relation, makes observed data can't be used for real oar forecast, and severe one causes propeller blade tip and pipe inner wall friction, collision to cause model to damage, and this is a problem that urgent need will solve.
Summary of the invention
The adjustment of catheter position and rigidly fix a difficult problem when effectively solving the spacious water experiment of shrouded propeller; The utility model proposes a kind of regulation fixing apparatus of propeller nozzle.
The technical scheme that the utility model adopts is:
A kind of regulation fixing apparatus of propeller nozzle, comprise firm banking, front link span, rear connecting frame, sensor, connection sword and conduit, firm banking is equipped with front link span by bolt, by bolt rear connecting frame is installed on the front link span, the rear connecting frame lower end has been bolted sensor, the sensor lower end is equipped with the connection sword, and connection sword and conduit are fixed together.
Conduit is stainless steel material; Front link span is provided with 6 Long Circle fixed orifices.
Advantage of the present utility model: use this device can adjust very exactly position, upper and lower, left and right and the vertical inclination angle of conduit, and can guarantee fixedlying positioning of conduit, guarantee the effectively correct of experimental result; This apparatus structure is simple simultaneously, and is easy to process, and is applicable to various types of catheter propeller moulds, has very high application value.

Fig. 1 is a kind of front view of regulation fixing apparatus of propeller nozzle;
Fig. 2 is a kind of left view of regulation fixing apparatus of propeller nozzle;
Fig. 3 is a kind of birds-eye view of regulation fixing apparatus of propeller nozzle;
Among the figure: 1, firm banking 2, front link span 3, rear connecting frame 4, sensor 5, connection sword 6, conduit.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, a kind of regulation fixing apparatus of propeller nozzle, comprise firm banking 1, front link span 2, rear connecting frame 3, sensor 4, connection sword 5 and conduit 6, firm banking 1 is equipped with front link span 2 by bolt, by bolt rear connecting frame 3 is installed on the front link span 2, rear connecting frame 3 lower ends have been bolted sensor 4, and sensor 4 lower ends are equipped with connection sword 5, and connection sword 5 is fixed together with conduit 6.
Sensor 4 upper ends are provided with screw thread, screwing the position and can conveniently adjust upper and lower displacement and the anglec of rotation by a plurality of bolts; Conduit 6 is stainless steel material; Firm banking 1 is provided with 4 Long Circle fixed orifices (in Fig. 3), be used for and front link span 2 the regulating of position when being fixed, front link span 2 is provided with 6 Long Circle fixed orifices (in Fig. 1), is used for and rear connecting frame 3 the regulating of position when being fixed.
Principle of work: firm banking 1 is fixed on the track of experiment trailer, when carrying out the spacious water experiment of screw propeller, can regulate by the Long Circle fixed orifice on firm banking 1 and the front link span 2 and the bolt on the sensor 4 position of conduit 6, so that catheter center's line overlaps with the propeller center line, guarantee the normal performance of conduit thrust, the undue oscillation of the model axle that causes when avoiding simultaneously shrouded propeller model High Rotation Speed system guarantees normally carrying out and the accuracy of sensor 4 test datas of experiment.
