Description

Propeller device capable of automatically avoiding underwater obstacles underwater

Technical Field

The utility model relates to a waters rescue ship technical field especially relates to an automatic propeller device who avoids obstacle under water.

Background

At present, most of water area rescue ship equipment is still more traditional, such as life buoys, life rafts, paradise with engines and the like, even if propelling equipment such as motor propellers, jet pump propellers, pipeline propellers and the like is matched, in order to obtain larger thrust, corresponding propellers with large diameters are often adopted, the larger the ship body is, the larger the blade diameter is, the longer the blade diameter is, and the longer the vertical length is inevitable, so that the draught is deep, the requirement on the water area environment is higher, once the ship enters complicated water areas such as shallow rivers, shoals or streets caused by urban inland inundation, the situations such as reef touching, grounding and the like or damage to power devices such as the propellers and the like can be avoided, the rescue efficiency is greatly improved, meanwhile, irreparable damage can be caused to the propelling equipment, and the propeller device capable of automatically avoiding obstacles or enabling the rescue boat carried by an aircraft to solve the problems.

SUMMERY OF THE UTILITY MODEL

The utility model provides an automatic propeller device of avoiding obstacle under water has solved the problem of proposing in the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an automatic propeller device who avoids obstacle under water, includes movable mounting propeller on the hull, keeps away the barrier connecting rod, the lift slip table is installed to hull support tail end on the hull, and sliding connection has a plurality of lift forked tail sliders on the lift slip table, and the propeller is all installed through the connecting plate to lift forked tail slider, and bottom one side of hull support all articulates there is the barrier connecting rod of keeping away of corresponding quantity, keeps away the barrier connecting rod can drive its lift with the outer wall sliding connection of propeller when the swing.

Preferably, a cross rod is connected between the adjacent connecting plates, and a balancing weight is installed on the cross rod.

Preferably, the propeller is a small-diameter propeller.

Preferably, the water inlet of the duct on the propeller is positioned below the water inlet of the propeller, so that water can be conveniently fed into the propeller.

Further, set up a plurality of spouts of evenly arranging on the lift slip table, the sealed setting in bottom of spout, sliding connection is in the spout about the lift forked tail slider, adopts the forked tail formula structure to guarantee the gliding stability about the lift forked tail slider is in the spout.

It is worth to say that, keep away barrier connecting rod is arc form, and its bottom sets up the arcwall face.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model provides an automatic propeller device of avoiding obstacle under water, because the water course is shallower when life saving equipment gos forward, can touch some barriers, when keeping away the barrier connecting rod and touch the barrier, hold up the propeller and carry out the rebound along the orbit of lift slip table to avoid the barrier. Along with the automatic lifting of the propeller, the water inlet of the duct is still below the water surface, so that the smooth water inlet can be ensured, and the thrust is kept. After passing through the obstacle, the underwater propeller moves downwards along the track of the lifting sliding table by means of self gravity, and the obstacle avoidance connecting rod rotates around the rotating shaft to gradually return to the initial position. And the normal working state is recovered, and the pure mechanical structure is utilized to realize smooth and harmless passing through the underwater barrier without influencing the thrust output of the propeller.

The invention has simple structure, shallow draft, safety, reliability, convenient operation and strong practicability, ensures that the navigation device can navigate in not only conventional water areas but also ultra-shallow water areas, and greatly expands the range of motion of the navigation device, in particular to urban waterlogging streets.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, a propeller device of automatic obstacle under avoiding underwater, include movable mounting propeller 2 on hull 1, keep away barrier connecting rod 7, lift slip table 4 is installed to hull support 101 tail end on hull 1, and sliding connection has a plurality of lift forked tail sliders 3 on the lift slip table 4, and propeller 2 is all installed through connecting plate 5 to lift forked tail sliders 3, and all articulated in bottom one side of hull support 101 have the obstacle of keeping away connecting rod 7 of corresponding quantity, keep away barrier connecting rod 7 can with the outer wall sliding connection of propeller 2 and drive its lift when the swing.

Each group of ducted propellers can be set to be linked and not linked through a transverse screw connecting rod according to needs, and the ducted propellers are in the prior art and are not specifically described.

Be connected with the horizontal pole between the adjacent connecting plate 5, install balancing weight 6 on the horizontal pole, guarantee that propeller 2 can descend to the normal position automatically under the action of gravity.

The propeller 2 is a propeller with small diameter, and in order to keep the same propelling force of the propeller, the vertical space is changed into the horizontal space under the condition that other factors are not changed and the same blade area is kept. The mode of adopting a plurality of horizontal path oars to replace the vertical large-diameter oars greatly reduces the draft.

Set up a plurality of spouts 401 of evenly arranging on the lift slip table 4, the sealed setting in bottom of spout 401, the gliding stability about slide connection is guaranteed in spout 401 to the lift forked tail slider 3 in the adoption forked tail formula structure in spout 401.

Duct water inlet 201 on propeller 2 is located the below, and the water of propeller 2 of being convenient for keeps away barrier connecting rod 7 and is the arcwall form, and its bottom sets up the arcwall face, when touching underwater barrier, but propeller 2 under automatic lifting protects it and does not harm, and trafficability characteristic is good, and because of its water inlet is downward, still under the surface of water, can ensure to intake smoothly to keep thrust.

When in use: when obstacle avoidance connecting rod 7 touches obstacle 8, it lifts up propeller 2 along sliding chute 401 of lift slip table 4 and moves upwards along with obstacle avoidance connecting rod 7 rotates to avoid obstacle 8. Due to the design that the culvert water inlet 201 is downward after the propeller 2 is lifted, the culvert water inlet 201 is still below the water surface, and water can be normally fed, so that the output of the thrust of the propeller is not influenced.

After avoiding barrier 8, propeller 2 relies on self gravity or the gravity of balancing weight 6 to move down along the spout 401 of lift slip table 4, keeps away barrier connecting rod 7 and rotates and get back to initial position gradually, resumes normal operating condition, utilizes pure mechanical structure to realize smoothly harmless mode through obstacle under water and does not influence the thrust output of propeller 2.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
