[0002] Tower-type CSP power stations use a large number of heliostats to focus sunlight onto the receiver at the top of the tower, generating high-temperature heat energy, which in turn drives the steam turbine to generate electricity. The precise alignment and stable operation of the heliostats are crucial to the efficiency of the entire CSP power station, and the coupling of the heliostat is one of the key components to ensure its stable operation. Currently, there are no suitable tools to assist in the maintenance of the heliostat couplings in CSP power stations, which results in a long maintenance time, great difficulty in operation, and low efficiency for the workers. Therefore, this paper proposes a special tool for the maintenance of the heliostat couplings in tower-type CSP power stations. Utility Model Content
