Abstract

The invention discloses a bionic fish oar as manual propeller, which comprises the following parts: fixing rack, pinch bar rack, handle, elevating rod, connecting piece of tail blade, fish tail blade and fixing rack in the head or tail, wherein the pinch bar rack connects fixing rack through shaft and bearing, which changes angle with bulk; the pinch bar rack displays paralleling quadrilateral frame with four contacts loading bearing or copper coil; one end of pinch bar rack connects handle and the other end lifts with interlocking lifting rod; the angle of fish tail blade displays 45 deg at lifting upwards or downwards, which generates pushing force.

Description

Bionic fish tail scull

Technical field: the present invention relates to a kind of manpower ship propeller, particularly a kind of utilization fluctuates and can effectively promote the bionic fish tail scull that canoe advances.

Background technology: traditional big shield is that the people is (by pushing through, win over) big shield that shakes to both sides, only be adapted at using on the bigger slightly ship, nowadays the mode that bigger slightly ship has adopted motor-driven screw propeller to advance basically, and canoe is not suitable for sculling because the mode that advances of sculling can make canoe scurry toward both sides, and the mode that propels a boat by oars efficient is very not high in fact, because the mode of rowing the boat is a discountinuity, be not successional.

Summary of the invention: the objective of the invention is to imitate the swimming method that whale and dolphin fish tail fluctuate, provide a kind of utilization to swing up and down the bionic fish tail scull that can produce effective propulsive force.Technical scheme of the present invention is to utilize hull and people's own wt and water to this relative equilibrium stabilization of hull buoyancy, adopt the mode of ripping bar frame to make lifting bar do perpendicular movement up and down, make the fish tail leaf of lifting bar bottom be subjected to the resistance of water and angulation and produce thrust.Technical scheme of the present invention is achieved in that bionic fish tail scull, comprise fixed mount, the ripping bar frame, handle, lifting bar, the caudal lobe attaching parts, the fish tail leaf, fixed mount is used for fixing on the quarter (or fore), the ripping bar frame is by axle and bearing Connection Bracket, make it to rotate with fixed mount, with hull energy angle changing, the ripping bar frame is made up of two vertical poles and two cross bars, but form the parallelogram frame of an angle changing, four contacts of himself all stud with bearing, its side connects handle, but the lifting bar that the opposite side interlock is attached thereto, the bottom of lifting bar connects the caudal lobe attaching parts and stretches in the water, and the backer up and down of fish tail leaf is arranged on the caudal lobe attaching parts, and the fish tail leaf is connected the caudal lobe attaching parts by copper band with axle.When handle was upwards shaken, a side interlock lifting bar of ripping bar frame because the resistance of water can make the fish tail leaf upwards turn over and lean against on the backer, formed 45 upwards with horizontal direction, and produces forward thrust towards decline; When handle was shaken downwards, a side interlock lifting bar of ripping bar frame because the resistance of water can make the fish tail leaf turn over and lean against down on the backer, formed downward 45 with horizontal direction downwards again towards rising, and produced forward thrust; The handle that so constantly fluctuates will obtain continuously forward thrust, and canoe is moved ahead fast.If when allowing the ship turnon left, only need handle toward turning right, and continue the handle that fluctuates; Otherwise right-hand corner is also like this.

The invention has the beneficial effects as follows: imitate whale and dolphin in the mode of wagging the tail in when swimming, allow the fish tail leaf along with the liter of lifting bar or fall, can and horizontal direction form downward or upward 45, and produce forward thrust; Compare with oar with traditional big shield, have and make little foot more steady, speed is faster, many characteristics such as more convenient operation.

Among the figure; The 1-fixed mount, 2-ripping bar frame, 3-handle, 4-lifting bar, 5 caudal lobe attaching partss, 6-fish tail leaf.

The specific embodiment:

Embodiment 1 is with reference to 1,2,3 bionic fish tail sculls, comprise fixed mount 1, ripping bar frame 2, handle 3, lifting bar 4, caudal lobe attaching parts 5, fish tail leaf 6, fixed mount 1 is fixed on stern, ripping bar frame 2 is by axle and bearing Connection Bracket 1, handle 3 is connected with ripping bar frame 2, lifting bar 4 tops are connected with a side of ripping bar frame 2, and backer's caudal lobe attaching parts 5 is fixed on the bottom of lifting bar 4 about having, and fish tail leaf 6 is connected caudal lobe attaching parts 5 by copper band with axle.When handle 3 was upwards shaken, an end interlock lifting bar 4 of ripping bar frame 2 was towards decline, and this moment, fish tail leaf 6 was because the resistance of water and stopping of last backer with horizontal direction formation 45 upwards, and make the following thrust of fish tail leaf 6 change into forward thrust (referring to Fig. 1); When handle 3 was shaken downwards, a side interlock lifting bar 4 of ripping bar frame 2 was towards rising, and fish tail leaf 6 forms downward 45 with horizontal direction, and makes the last thrust of fish tail leaf 6 change into forward thrust (referring to Fig. 2) owing to the resistance of water and stopping of following backer at this moment.And the handle 3 that constantly fluctuates just makes fish tail leaf 6 produce the continuous uninterrupted forward thrust; Thereby obtain than traditional big shield or the higher forward thrust of oar efficient to ship.If when allowing ship turn left, only need handle 3 toward turning right and the handle 3 that continues to fluctuate get final product; Otherwise, as will allow ship bend to right the time, only need handle 3 toward turning left and the handle 3 that continues to fluctuate get final product.

Embodiment 2 is fixed on fore with reference to Fig. 3,4,5 fixed mounts 1, and caudal lobe attaching parts 5 is connected together with fish tail leaf 6 and lifting bar 4 bottoms, and becomes among the embodiment 1 oppositely, and all the other are identical with embodiment 1.

Claims

1. bionic fish tail scull, comprise fixed mount, ripping bar frame, handle, lifting bar, caudal lobe attaching parts, fish tail leaf, be characterized in: fixed mount can be fixed on stern, also can be fixed on fore, the ripping bar frame by the axle be connected with fixed mount with bearing, can with the hull angle changing; The ripping bar frame is made up of two vertical poles and two cross bars, but form the parallelogram frame of an angle changing, its four contacts all stud with bearing, one side of ripping bar frame is connecting handle, but opposite side interlock lifting bar is made vertical displacement movement up and down, and backer's caudal lobe attaching parts is fixed on the bottom of lifting bar about having, and the fish tail leaf is connected the caudal lobe attaching parts by copper band with axle, the fish tail leaf is along with the liter of lifting bar or fall the 45 that can form downward or upward, and produces forward thrust.
