Waterpower propelling device

Abstract

A waterpower propelling device comprises an upper platform and a lower platform. A longitudinal displacement driving motor is set up on the upper platform, a guide rail and sliding block mechanism isfixed to the upper platform, and a lead screw drives a moving plate to do longitudinal linear reciprocating motion on the upper platform. The lower platform is fixed to the moving plate, a transversedisplacement driving motor is fixed to the upper layer of the lower platform, a lower guide rail and sliding block mechanism is fixed to the lower layer of the lower platform, and a left-handed lead screw and a right-handed lead screw rotate at the same time to drive two flange type lead screw nuts, flange type lead screw nut connecting plates, lower sliding blocks and moving blades to simultaneously do linear reciprocating motion in the same direction or different directions. The movable blades are matched with a middle fixed blade, and the middle fixed blade is fixed to the lower platform through a blade fixing plate. According to the waterpower propelling device, a large flow can be obtained at a low propulsion speed, and the fluidity of riverway water flow is improved; a large amount of unnecessary economic loss is avoided; and the problem of high energy consumption caused by operation of a pump station under a low lift is avoided, damage to organisms flowing through the device canalso be avoided, and ecological friendliness is achieved.

Description

technical field [0001] The invention belongs to the technical field of hydrodynamic propulsion, and in particular relates to a hydrodynamic propulsion device. Background technique [0002] The terrain of the plain is low and flat, the hydraulic gradient in the upstream and downstream is extremely small, and some capillary-shaped rivers lack water supply, and the flow power is insufficient. The impact of human beings on the rivers within the living area is becoming more and more obvious. The construction of cities has changed the natural form of the rivers, resulting in the shrinkage of the river network, the decline in connectivity, and the weakening of regulation and storage capacity. In addition, a large amount of domestic and industrial sewage has been discharged. Into the river, aggravated the deterioration of the water quality and the ecological environment of the river in the plain city. Therefore, the fluidity of the river flow is an urgent problem to be solved. [...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems existing in the prior art, the object of the present invention is to provide a hydrodynamic propulsion device, which can effectively meet the requirements of obtaining a relatively large flow rate at a relatively low propulsion speed, realize water body propulsion, and accelerate the fluidity of river water flow; the device It replaces the work of the pumping station and at the same time saves a lot of unnecessary economic loss compared with the establishment of the pumping station; at the same time, the moving speed of the blades is small, the operation of the device is relatively stable, the hydraulic performance can be greatly improved, and the pumping station is avoided. The problem of high energy consumption when operating under low lift can well complete the water propulsion work in the plain capillary river network; the low-speed blades can also avoid damage to over-current organisms and achieve eco-friendliness
