Intelligent Stirling engine start control device

Abstract

The invention discloses an intelligent Stirling engine start control device which comprises a concentration element, a Stirling engine, a temperature sensing unit, a control unit, a start motor, a power storage element, an electric generator and a second sensing unit. The concentration element is used for concentrating heat energy of sunlight on a concentration action zone. The Stirling engine is located in the concentration action zone. The temperature sensing unit is arranged in the concentration action zone and used for sensing the temperature of the concentration action zone and outputting a temperature sensing signal. The temperature sensing signal and an electric sensing signal are mainly received through the control unit, so that when the Stirling engine is under the state that the temperature sensing signal reaches a preset value but the electric sensing signal does not exist, a start signal is sent by the control unit, the Stirling engine is started by the start motor, and the control device automatically starting the Stirling engine can be obtained.

Description

technical field [0001] The invention relates to a Stirling engine, in particular to an intelligent Stirling engine startup control device. Background technique [0002] At present, after a large amount of oil is exploited and used, its storage capacity has been reduced day by day, and its price has continued to rise, and the carbon dioxide and other gases emitted by the extensive use of oil and other fuels have caused ozone layer damage and greenhouse effects. Based on the above-mentioned reasons, there are various schemes for providing alternative energy sources such as solar energy, hydropower or wind power, which has obviously become an important topic that the industry needs to study. [0003] The known Stirling engine mainly includes a cylinder and a piston accommodated inside the cylinder, the piston can move inside the cylinder, and the cylinder has a heating end and a cooling end, and the piston is connected to a connecting rod , and directly or indirectly connected...

AI Technical Summary

Problems solved by technology

[0007] 1. Known "solar heat storage type Stirling engine power generation device" and "Stirling power plant combined with lens", if the temperature of the heat source is insufficient, the Stirling engine cannot continue to be driven, and the Stirling engine stops. , when restarting, the Stirling engine must be started manually, that is, the Stirling engine must be restarted manually, which is obviously a waste of manpower

[0008] 2. It is known that neither the "solar heat storage Stirling engine power generation device" nor the "Stirling power device combined with lens" can accurately know whether the temperature of the heat source gathered by sunlight has reached the working temperature, so it is impossible to effectively control the restart the right time

[0009] 3. The existing solar Stirling engine will stop operating when there is insufficient heat source caused by weather factors such as rainy or night, but when the working temperature returns to normal, for example, the existing solar Stirling engine cannot start automatically
