Problems solved by technology

[0002] There are already some downhole power generation devices, such as the technical solutions disclosed in the announcement numbers CN10208057A and CN206647203U, but most of these existing downhole power generation devices only use a single power generation method of the turbine, and can only drive one power generation mechanism to generate electricity
Once the power generation mechanism or turbine fails, it will not be able to provide a stable power supply, affecting the normal use of downhole instruments

Abstract

The invention discloses a downhole turbine piezoelectric hybrid power generation device. The device comprises an upper joint, a central flow pipe, a fixed impeller, a power generation set shell, a rotary impeller, a piezoelectric poking piece, a poking piece contact, a motor gear, a driving gear, a connecting main body and a power generator, injected water flows through the fixed impeller and therotary impeller to enable a piezoelectric ceramic in the fixed impeller to vibrate and enable the rotary impeller to rotate, and the rotary impeller rotates to drive the generator to rotate and drivethe piezoelectric poking piece to vibrate. The power generation device can provide a stable power supply for electrical apparatus elements such as a blanking plug, a flow meter, a pressure force sensor and a control circuit board in an intelligent water distributor, is more stable and reliable compared with the technical means such as downhole wireless power transmission and downhole power supplyby a ground cable in the prior art, and solves the problem of insufficient downhole power.

Description

technical field [0001] The invention relates to a device applied in the field of oilfield water injection, in particular to a charging device applicable to an intelligent water distributor. Background technique [0002] There are already some downhole power generation devices at present, such as the technical solutions disclosed in the announcement numbers CN10208057A and CN206647203U, but most of these existing downhole power generation devices only use a single power generation method of a turbine, and can only drive one power generation mechanism to generate electricity. Once the power generating mechanism or turbine breaks down, a stable power supply cannot be provided, affecting the normal use of downhole instruments. Contents of the invention [0003] In order to solve the technical problems mentioned in the background technology, the present invention provides an underground turbine piezoelectric hybrid power generation device, which uses a turbine power generation ...
