Telescopic tidal power generation device

Abstract

The invention discloses a telescopic tidal power generation device. The device comprises a shell, a water inlet mechanism, a first water inlet frame, a second water inlet frame, a transmission mechanism, a rotating rod, turbines, a power generator body, a filtering mechanism, transverse rods, abutting rods, filter screens, springs and pressed blocks. The device has the beneficial effects that in the process that tidal water flow enters the first water inlet frame and the second water inlet frame, the water flow firstly passes through the filter screens so that some waste pollutants in seawatercan be filtered out by the filter screens, and the waste pollutants are prevented from entering the shell; and furthermore, the turbines rotate to drive the transverse rods and the abutting rods to rotate, along with continuous rotation of the abutting rods, extrusion abut against is carried out on the pressed blocks, the pressed blocks are subjected to extrusion abut against and then force is transmitted to the filter screens and the springs, the springs contract under pressure and return after the pressure is disappeared, and therefore the filter screens are driven to continuously shake, the filter screens are prevented from being blocked by the pollutants, the effect of the filter screens is further improved, and the safety of an internal structure of the shell is ensured.

Description

technical field [0001] The invention relates to a power generation device, in particular to a telescopic tidal power generation device, which belongs to the technical field of tidal power generation. Background technique [0002] The principle of tidal power generation is similar to that of ordinary hydropower. By going out of the reservoir, the seawater is stored in the reservoir at high tide and stored in the form of potential energy. Then, the seawater is released at ebb tide, and the water turbine is driven to rotate by using the difference between high and low tide levels. , drive the generator to generate electricity. Tide is a kind of renewable energy with huge reserves, inexhaustible supply, no need for exploitation and transportation, clean and pollution-free. The construction of tidal power stations does not require resettlement, does not submerge the land, and has no environmental pollution problems. It can also be combined with tidal power generation to develop ...

Problems solved by technology

[0003] In the patent application with the application number 201520213110.6, "a small power generation device that can use tidal power generation" is announced, which realizes a tidal power generation device with a high energy conversion rate. When the above patent is actually used, due to the current Seawater pollution is relatively serious. There are often some waste pollutants floating on the sea surface, especially near the sea surface. When seawater enters the device through the water inlet, some waste pollutants may be carried into the device, which will affect the internal structure of the device. affect or even damage
