Abstract

The utility model relates to a manpower propeller for a boat, particularly a bionic fish tail scull which can effectively propel the boat to move forward utilizing the swing from top to bottom. The utility model can be installed at a boat tail and can also be installed at a boat head. The bionic fish tail scull comprises a fixed frame, a lever frame, a handle, a lifting rod, a connecting piece for tail blades and fish tail blades, wherein the fixed frame is fixed at the boat tail or the boat head; the lever frame is connected with the fixed frame through shafts and bearings, and the angle between the lever frame and a boat body can be changed; the lever frame is like a frame of a parallelogram which has changeable angles, and four contact points of the lever frame are all inlaid with bearings or copper rings; one end of the lever frame is connected with the handle, and the other end connected with the lifting rod in a linking mode can do vertical lifting movements from top to bottom; the fish tail blades can form a downward angle of 45 DEG or an upward angle of 45 DEG following the raising or the falling of the lifting rod and can generate front pushing force. If the bionic fish tail scull is installed at the boat head, the connecting piece for the tail blades and the fish tail blades are connected with the bottom end of the lifting rod and are arranged in the direction which is reverse to that of the connecting piece for the tail blades and the fish tail blades when the bionic fish tail scull is installed at the boat tail. Compared with the traditional scull and paddle, the utility model used on the boat has the advantages of more stable running of the boat, faster speed and more convenient operation.

Description

Bionic fish tail scull

Technical field: the utility model relates to a kind of manpower ship propeller, and 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 purpose of this utility model is to imitate the swimming method that whale and dolphin fish tail fluctuate, and provides a kind of utilization to swing up and down the bionic fish tail scull that can produce effective propulsive force.The technical solution of the utility model 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.The technical solution of the utility model 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, but the ripping bar frame is as the parallelogram frame of an angle changing, four contacts of himself all stud with bearing (or copper band), its end connects handle, but the lifting bar that other end interlock is attached thereto, the bottom of lifting bar connects the caudal lobe attaching parts and stretches in the water, the backer up and down that the fish tail leaf is arranged on the caudal lobe attaching parts, the fish tail leaf is connected the caudal lobe attaching parts by copper band with axle.When handle was upwards shaken, an end 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, an end 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 beneficial effects of the utility model are: 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 an end 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, an end 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.
