Description

Technical Field

[0001] The present invention relates to the technical field of geothermal power generation, and in particular to a dual-mode free-switching geothermal power generation device. Background Art

[0002] Thermal power generation is a new type of power generation technology that uses underground hot water and steam as a power source. Its basic principle is similar to that of thermal power generation, and is also based on the principle of energy conversion. Geothermal power generation is actually an energy conversion process that converts underground thermal energy into mechanical energy, and then converts mechanical energy into electrical energy, or geothermal power generation. Geothermal energy is renewable thermal energy from deep in the earth, which originates from the decay of the earth's molten magma and radioactive substances.

[0003] Existing geothermal power generation devices often generate electricity solely through geothermal energy during use. However, the fan blades of the power generation often need to be repaired and maintained regularly under the impact of steam for a long time, so the geothermal power generation device needs to be shut down, which further directly affects the efficiency of power generation. As a result, it is impossible to carry out repairs and maintenance without shutting down, which directly reduces the efficiency of power generation and further leads to the poor practicality of the geothermal power generation device.

[0013] The beneficial effects of the present invention are:

[0014] 1. When the present invention repairs the generator and other parts on the left side, the valve on the left side is closed, and the high-temperature gas will be reused through the guide pipe on the right side. At the same time, the high-temperature resistant air pressure cylinder on the right side begins to extend, thereby driving the push plate and the adjusting blades to extend along the positioning blades, thereby increasing the power generation efficiency, thereby making up for the power generation gap during maintenance on the left side, thereby ensuring that the geothermal power generation device can still be repaired and maintained during operation, thereby ensuring the practicality of the geothermal power generation device.

[0015] 2. The left-right symmetrical generator of the present invention has the same principle, thus realizing a dual power generation mode, thereby ensuring the electricity for the user when in use, and is provided with a push plate that can retract and extend. At this time, the high-temperature resistant pneumatic cylinder begins to extend, thereby driving the adjusting blades to begin to move outward along the positioning blades, thereby realizing the real-time adjustment of the contact area of ​​the adjusting blades and the positioning blades with respect to the wind force, further ensuring that the rotation speed of the power generation shaft can be adjusted, further ensuring that the amount of electricity generated can be adjusted, thereby ensuring the practicality and flexibility of the geothermal power generation device.

[0016] 3. In the present invention, high-temperature steam enters the power generation chamber, passes through the left-right symmetrical feed pipe, and then enters the heat conduction plate. In the process of flow, the heat of the high-temperature steam will produce a certain loss. At this time, the refrigerator starts to refrigerate, so that its heat conduction plate starts to cool down. At this time, the heat conduction plate cools the steam in the conversion chamber, so that its vaporization is converted into liquefaction. At this time, the liquid enters the water guide pipe, and then enters the water storage chamber through the main one-way valve, thereby realizing the recycling of water flow, further reducing the waste of water resources, and then reducing the cost of use, thereby ensuring the practicality of the geothermal power generation device.

[0036] The dual-mode free-switching geothermal power generation device of the present invention has the following working process:

[0037] During operation, the geothermal high-temperature gas passes through the steam pipe 31, and the steam pipe 31 quickly heats the water in the water storage chamber 29. The water begins to vaporize and expand rapidly and sprays out. At this time, the high-temperature gas enters the diversion chamber 25 through the lifting pipe 27. At this time, the valves 26 on the left and right sides are in an open state. At this time, the gas passes through the guide pipe 23 and sprays out from the nozzle 16 quickly, thereby generating a strong airflow. At this time, the airflow will impact the adjusting blades 22 and the positioning ring 18, and the adjusting blades 22 and the positioning blades 19 start to rotate at a high speed, thereby The generator shaft 17 is driven to start rotating at a high speed, and then the generator 13 starts to generate current. At this time, the left and right symmetrical generators 13 have the same principle, thereby realizing a dual power generation mode, thereby ensuring the power of the user when in use, and a push plate 21 that can be telescopically moved is provided inside. At this time, the high-temperature resistant pneumatic cylinder 20 starts to extend, thereby driving the adjusting blades 22 to start moving outward along the positioning blades 19, thereby realizing the real-time adjustment of the contact area of ​​the adjusting blades 22 and the positioning blades 19 with respect to the wind force, further ensuring that the rotation speed of the generator shaft 17 can be adjusted.

[0038] At this time, when the high-temperature steam enters the power generation chamber 15, it passes through the left-right symmetrical feed pipe 38 and enters the heat conduction plate 37. In the process of flow, the heat of the high-temperature steam will be lost to a certain extent. At this time, the refrigerator 36 starts to cool, so that the heat conduction plate 37 starts to cool down. At this time, the heat conduction plate 37 cools the steam in the conversion chamber 35, so that its vaporization is converted into liquefaction. At this time, the liquid enters the water guide pipe 32, and then enters the water storage chamber 29 through the main one-way valve 34, thereby realizing the recycling of water flow.

[0039] When maintenance is needed, the generator 13 and other parts on the left are maintained, and the valve 26 on the left is closed. The high-temperature gas will be reused through the guide pipe 23 on the right. At the same time, the high-temperature resistant pneumatic cylinder 20 on the right begins to extend, thereby driving the push plate 21 and the adjusting blades 22 to extend along the positioning blades 19, thereby increasing the power generation efficiency, thereby making up for the power generation gap during maintenance on the left side, thereby ensuring that the geothermal power generation device can still be maintained during operation, thereby ensuring the practicality of the geothermal power generation device. At this time, by turning the screw 40 and the nut 41, the installation cover 42 is opened, so that the positioning ring 18 and the positioning blades 19, the adjusting blades 22, the power generation shaft 17 and other parts on the left are repaired and maintained.
