Bionic hydrodynamic propulsion device

Abstract

The invention discloses a bionic hydrodynamic propulsion device which comprises a fixing plate, a driving motor, a first crank transmission mechanism, a second crank transmission mechanism and a propulsion plate, and the driving motor, the first crank transmission mechanism and the second crank transmission mechanism are all arranged on the fixing plate. Connecting shafts are arranged between thedriving motor and the first crank transmission mechanism and between the first crank transmission mechanism and the second crank transmission mechanism respectively, the driving motor drives the firstcrank transmission mechanism and the second crank transmission mechanism to move, and the first crank transmission mechanism and the second crank transmission mechanism reciprocate to drive the propelling plate to swing. According to the invention, the flowability of riverway water flow can be accelerated, the hydraulic performance can be greatly improved, meanwhile, harm to overflowing organismscan be avoided, and the ecological friendliness is realized. The device is simple in structure, low in manufacturing cost and energy consumption, capable of adapting to various river working conditions, wide in application range and capable of efficiently and stably operating for a long time.

Description

Technical field[0001]The present invention belongs to the field of hydraulic propulsion technology, and more particularly to a bionic water power propulsion device.Background technique[0002]The terrain is low in the plain area, and the upper and downstream hydraulic slope is extremely small, which leads to a slow flow of water flow in some plain river networks or even stagnation, and the water flow is insufficient. At the same time, human activities and river structure and influence have become more serious. On the one hand, the construction of the city has changed the natural form of the river, leading to shrinking the river network water system, decline in connection, weakened, on the other hand, there is a lot of life and industrial Sewage is discharged into the river, exacerbating the water quality deterioration and ecological environment degradation of the river in the plain city. Therefore, the problem of fluidity in river water flow is an urgent problem to be solved.[0003]For...

Problems solved by technology

For some capillary-shaped river networks, the construction of pumping stations will greatly increase the cost, and the input and output are extremely mismatched, resulting in high construction costs. At the same time, for capillary-shaped river networks, the head requirements are low or even close to zero. Head, when operating under such working conditions, on the one hand, the efficiency is reduced and the energy consumption is greatly increased. On the other hand, the safety and stability of the pump station such as vibration and cavitation are under great test. Aquatic organisms usually cause unavoidable impact damage or even death, which cannot meet the requirements for long-term efficient and stable operation of river water ecological improvement
