Location measurement device suitable for thermal collector upright column in groove type photo-thermal power generation

Abstract

The invention discloses a location measurement device suitable for a thermal collector upright column in groove type photo-thermal power generation. The location measurement device comprises a concentric adaption seat (1), a measurement prolonging rod (2), fixing pieces (3) and two small prisms (4), wherein the bottom of the concentric adaption seat (1) is installed in a curved surface shaft seatof the thermal collector upright column; the center point of the concentric adaption seat (1) and that of the curved surface shaft seat are overlapped; the measurement prolonging rod (2) is fixed intoa guide groove through the fixing pieces (3); the guide groove is formed in the top of the concentric adaption seat (1); the center line of the measurement prolonging rod (2) and that of the concentric adaption seat (1) are overlapped; through holes are symmetrically formed in the two sides of the measurement prolonging rod (2) along the center point of the measurement prolonging rod (2); the twosmall prisms (4) are correspondingly fixed into the two through holes; and the two small prisms (4) are measured to obtain measurement data so as to achieve location measurement. The various curved surface shaft seats can be located accurately, it is guaranteed that the position of the thermal collector upright column is accurate, and the accuracy requirement is met.

Description

technical field [0001] The invention relates to a positioning measuring device suitable for a heat collector column in a trough photothermal power generation, and belongs to the technical field of photothermal power generation. Background technique [0002] In the construction of trough solar thermal power generation, the columns of the collector are arranged linearly to support the collector to track the sun and rotate in real time. According to the working principle of the collector equipment, the collinearity requirements of each equipment are extremely high, so the spatial coordinate position accuracy of the collector column is extremely high. [0003] During the construction of trough-type photothermal power generation Sun Island project, the principle of trough-type photothermal power generation is that the reflector of the collector reflects sunlight and precisely focuses on the heat-collecting tube on the focal line of the reflector, so that the temperature of the he...
