Problems solved by technology
[0002] The ground-based optical telescope is an important optical instrument for space detection. It is widely used in the fields of space exploration and astronomical observation. With the needs of detection and the continuous advancement of technology, the aperture of the primary mirror is increasing. As the weight continues to increase, when the observation is rotated, the uneven distribution of gravity will seriously affect the image quality. In order to ensure the stability of the relative position of the main mirror and the mirror chamber in the prior art, various support schemes have been proposed, including mechanical support , pneumatic support and hydraulic support, however, due to its unreasonable structure, the deviation between the main mirror and the mirror chamber is relatively large, the corresponding speed of the system is slow, and the energy consumption is high

The invention discloses a hydraulic supporting device for a main lens of an astronomical telescope, belongs to the field of astronomical telescopes, and mainly relates to a hydraulic supporting device. In order to solve problems in the prior art that the main lens and a lens chamber of a telescope supporting system are larger in deviation because the structure of the telescope supporting system is not reasonable, the corresponding speed is slow, and the energy consumption is large. A longitudinal hydraulic supporting assembly comprises a plurality of longitudinal hydraulic cylinder groups, and is disposed at the lower end of the main lens. An adjustment unit comprises a signal adjustment assembly and a pressure adjustment assembly. The output end of a control unit is connected with the signal adjustment assembly and the pressure adjustment assembly, and the output end of the signal adjustment assembly and the output end of the pressure adjustment assembly are respectively connected with the longitudinal hydraulic cylinder groups through a miniature flow pump. The miniature flow pump is used for achieving the flow control of the longitudinal hydraulic cylinder groups in different areas, and the device is precise in control, is small in system power, and is small in occupied space.
