The invention relates to a power generation device with an anti-blocking function for power generation by using
geothermal energy. The power generation device comprises a circulating
pipe, a cleaningtank, an ash
storage tank, a heat exchange tank, a power generation tank, a heat conduction mechanism, a power generation mechanism, a descaling mechanism and a backfilling mechanism, wherein the descaling mechanism comprises a filtering
pipe, a water inlet and a flushing unit; the flushing unit comprises a water pump and an ash removal
pipe; the power generation mechanism comprises a storage battery, a charging unit, a rotary shaft, a
turbine and a bearing housing; the charging unit comprises a power generator casing, a coil and at least two magnets. The power generation device with the anti-blocking function for power generation by using
geothermal energy has the advantages that by arranging the descaling mechanism, the suspension particles, gas, microorganisms and clay matters in
geothermal water can be effectively removed, the blockage of a pipeline is avoided, the maintenance time is shortened, and the maintenance cost is reduced; by matching with the power generation mechanism and the heat conduction mechanism, the
heat energy in the
geothermal water can be effectively utilized, the power generation efficiency is improved, and the power generation amount of the power generation device is increased.
