Modularization double-swing solar energy automatic tracking apparatus

Abstract

The invention belongs to the field of solar energy utilization, and discloses a modularization double-swing solar energy automatic tracking apparatus, for the purpose of providing an apparatus which performs real-time tracking of the sun in a hyper-hemisphere space, is provided with two similar swing kinematic pairs, and aims at reducing part types of an execution mechanism. The apparatus at least comprises a receiving frame, an upper swing module, a lower swing module and a pedestal module. The upper swing module is at least composed of an upper base module and an upper precision deceleration module. The lower swing module is at least composed of a lower base module and a lower precision deceleration module. The upper swing module and the lower swing module are axially installed in an orthogonal mode. The whole upper swing module swings around the lower transmission shaft of the lower swing module. The receiving frame swings around the upper transmission shaft of the upper swing module.

Description

technical field [0001] The invention relates to a modular double-swing solar automatic tracking device, which belongs to the field of solar energy utilization. Background technique [0002] my country's energy structure is dominated by coal, accounting for about 70%, followed by oil, accounting for about 21%. The reserves of fossil fuels such as coal and petroleum are certain. "China's Expansion of Domestic Demand and Development of Renewable Energy" and other materials state that by the end of this century, the world will face a situation where there will be no coal to burn. Among the new energy represented by solar energy, geothermal energy, nuclear energy, etc., solar energy is undoubtedly the cleanest renewable energy, and has the advantages of being inexhaustible. my country has a vast territory and abundant solar energy resources. Making full use of solar energy resources and improving its utilization efficiency is one of the good strategies to solve the energy crisi...

Problems solved by technology

The mechanism of this scheme has good rigidity, but the reverse solution of the parallel mechanism is extremely cumbersome. Both the spherical hinge and the Hooke hinge have limited range of movement angles. Whether the mechanism can reach the hemispherical space or the spherical hinge (or Hooke hinge) in the hemispherical space Is there any interference unknown or known

The Chinese patent with the patent number ZL200620167990.9 discloses an automatic sun tracking device. The key point of the scheme is: to achieve the tracking requirements by controlling the intermittent movement of a group of ratchet mechanisms and the movement of the cam mechanism. This scheme has high tracking accuracy, but the scheme The kinematic connections are all connected by high pairs (points and surfaces). The pawls and the pointed push rods that cooperate with the cams are easy to wear, and the precision retention needs to be improved.

The application number is 200810300158.5, the application number is the device disclosed in Chinese patents such as 200910310148.4, and its key points of the scheme all can be attributed to a circular motion in a horizontal plane and a swing in a vertical plane. The scheme is all simple and practical, but its horizontal rotation and The vertically oscillating actuators need to be designed and manufactured separately
