The present application provides a base station, a method for locating a base station, and corresponding equipment. The method for locating a base station includes: specifying the current base station as the initial reference base station of the current cell; The position calibration information of the initial reference base station; screening out the corresponding re-measurement base station whose error value is greater than the preset threshold in the position calibration information; receiving the feedback of the re-measurement base station relative to the calibrated base station based on the second ranging strategy position calibration information, and correct the position calibration information of the retested base station. Through the cooperation of the first ranging strategy and the second ranging strategy, the problems of limited positioning accuracy of the base station and complicated positioning calculation methods are overcome, and the base station whose position calibration information error value is greater than the preset threshold can be retested, and the The fusion of the two positioning methods can effectively improve the accuracy of self-calibration between base stations.

This invention discloses a kind of single ply parallel connection three degree of freedom one-piece compliance accurate positioning platform that has redundancy. This invention includes base and motion platform. The motion platform and the base are connected by four group compliance positioning amplification frames. The four group amplification frames are in 900 rotating symmetry on the four sides of the motion platform. This invention can achieve nanometer positioning accuracy; the positioning platform has good operationality. It can avoid singular position, solve the coupling problem of input and output and increase its working flexibility. This invention can enlarge the motion scope by using secondary grade or more high level compliance amplification frame.

The invention discloses a gas producer deslagging device which comprises a slag plate, a supporting part arranged on the bottom of the slag plate, a driving part for driving the slag plate to rotate and an airduct. The slag plate comprises a plate body, a rotary sleeve disposed on the bottom of the plate body, a supporting runner and spacing teeth.
