Embodiment 1

[0023] see figure 1 and 2 , a variable transmission ratio water turbine, comprising a first rotating frame 3, the right side of the first rotating frame 3 is fixedly connected to a fixed seat 2, the fixed seat 2 is fixedly connected to a second rotating frame 11, and the fixed seat 2 is fixedly connected to the impeller 1 , the first rotating frame 3 is slidably connected to the rotating shaft 10, the second rotating frame 11 is slidably connected to the rotating shaft 10, the right side of the rotating shaft 10 is fixedly connected to the control handle 20, the left side of the rotating shaft 10 is fixedly connected to the sleeve 9, and the right side of the sleeve 9 The first external gear 8 is fixedly connected, and a gear connector 7 is provided between the first external gear 8 and the second external gear 6. The left side of the sleeve 9 is fixedly connected to the second external gear 6, and the second external gear 6 is connected to the second internal gear. Gear 5, t...

Embodiment 2

[0025] see image 3 , the second embodiment is improved on the basis of the first embodiment, the left side of the first rotating frame 3 is fixedly connected to the guide cover 26, the resistance of the device to the water flow can be reduced through the guide cover 26, and the water flow is guided to the impeller 1 direction, thereby strengthening the impact of the water flow on the impeller 1; the left side of the rotating shaft 10 is fixedly connected to the first limit block 27, and the part of the rotating shaft 10 located in the fixed frame 13 is fixedly connected to the second limit block 28. During the process, to prevent the operator from pulling the rotating shaft 10 through the control handle 20 to slide excessively, causing the entire rotating shaft 10 to be detached from the device, so two limit blocks are provided. When holding the control handle 20 and sliding the rotating shaft 10 to the right, it slides to the limit position. At this time, the first stopper 2...

Abstract

The invention relates to the technical field of water turbine power generation, and discloses a transmission ratio changeable water turbine. A first rotation frame is included. The right side of the first rotation frame is fixedly connected with a fixing base. The fixing base is fixedly connected with a second rotation frame and fixedly connected with an impeller. The first rotation frame is in sliding connection with a rotation shaft. The left side of the rotation shaft is fixedly connected with a sleeve. The right side of the sleeve is fixedly connected with a first outer gear. The left sideof the sleeve is fixedly connected with a second outer gear connected with a second inner gear. The transmission ratio changeable water turbine can be used in a hydraulic engineering power generationdevice, a changing device capable of changing the transmission ratio is composed of a first inner gear, the second inner gear, the first outer gear and the second outer gear, the rotation ratio of awhole power generation device is adjusted through the transmission ratio changeable device, accordingly, the whole device can be applicable to flow fields different in water flow, the transmission ratio is switched according to different water flow degrees, the power generation efficiency is higher, and the transmission ratio changeable water turbine is worthy of usage and popularization.

Description

technical field [0001] The invention relates to the technical field of water turbine power generation, in particular to a variable transmission ratio water turbine. Background technique [0002] A hydroelectric generator is a generator that uses a water turbine as the prime mover to convert water energy into electrical energy. When the water flows through the water turbine, the water energy is converted into mechanical energy, and the rotating shaft of the water turbine drives the rotor of the generator, which converts the mechanical energy into electrical energy and outputs it. It is the main power equipment for generating electric energy in hydropower stations. [0003] Chinese patent (publication number: CNU207939294U) discloses a micro-hydraulic generator, including a generator body; a water turbine connected to the generator body, and the generator body includes a frame, which is fixedly installed behind the frame The rear cover on the side, which forms a certain acco...
