Problems solved by technology

The disadvantages of this positioning device are:
[0008] 1) The rotation range is limited. When the sun's rays are close to the level in the morning or evening, the driving force arm of the hydraulic device is limited, making it difficult for the solar receiving plate to move to the corresponding position, and the solar receiving plate can only be within a certain range track the sun;
[0009] 2) The mechanism of the motor-driven positioning device has low operating accuracy and poor stability;
[0010] 3) The power of the motor is limited. For a solar system with a large size and weight, it is not realistic to use a motor drive

specific Embodiment approach

[0042] In this manual:

[0043] 1) The control device does not belong to the inventive point of the present invention, so it will not be explained in detail in this specification.

[0044] 2) The ground and the roof refer to the location where the solar system is fixedly installed, and are not limited to this, and are only used as a guide.

[0045] 3) The hydraulic cylinder includes a hydraulic cylinder liner and a piston or guide rod slidingly installed in the cylinder liner. In this specification, the cylinder liner is defined as a fixed part, and the movable guide rod or piston is defined as an action part.

[0046] 4) Horizontal direction: the direction parallel to the ground; height direction: the direction perpendicular to the ground.

[0047] 5) Dead point: The hydraulic cylinder of the second hydraulic system and the push rod connected to it are in a straight line.

[0048] like figure 1 , figure 2 In the shown solar system, the solar system includes a solar posit...

Embodiment 1、2、3

[0082] like Figure 1 to Figure 9 The illustrated second hydraulic system includes two hydraulic cylinders: a first hydraulic cylinder 700 and a second hydraulic cylinder 701 .

[0083] The central shaft 5 is provided with fixedly installed push rods: the first push rod 600 and the second push rod 601, and the first ends of the first hydraulic cylinder 700 and the second hydraulic cylinder 701 are connected with the first push rod 600 and the second push rod respectively. The rod 601 is hinged. Two fixed seats are fixedly installed on the ground or on the roof: the first fixed seat 710 and the second fixed seat 711, and the second ends of the first hydraulic cylinder 700 and the second hydraulic cylinder 701 are connected with the first fixed seat 710 and the second fixed seat respectively. The fixing seat 711 is hinged.

[0084] During specific implementation, the hydraulic cylinders of the second hydraulic system can apply pushing force to the turntable at the same time, c...

Abstract

A positioning device for a solar receiving system, the solar system includes a positioning device and a solar light receiving panel fixedly installed on the positioning device, the positioning device includes: a rotating member: it can rotate on its axis; a turntable: It is fixedly connected with the rotating member, and rotates with the rotation of the rotating member. When the rotating frame rotates, it drives the solar receiving plate to rotate accordingly; the second hydraulic system: used to drive the rotating frame to rotate with the axis of the rotating member as The shaft rotates; the second hydraulic system includes at least two hydraulic cylinders, and the second hydraulic system is also provided with a fixed seat fixedly installed on the ground or on the roof corresponding to each hydraulic cylinder, and the first hydraulic cylinder of each hydraulic cylinder One end is respectively hinged with each fixing seat, and its second end is respectively connected with the rotating member in a hinged manner.

Description

technical field [0001] The invention relates to the field of new energy, and more specifically, relates to a positioning device for a solar energy receiving system. Background technique [0002] In a dish solar system or a photovoltaic solar system that performs two-dimensional tracking, the tracking accuracy of the positioning device to the sun's azimuth is an important factor that affects its work efficiency and energy utilization. For example, compared with ordinary fixed photovoltaic solar energy systems, if a solar photovoltaic panel with the same area can always be perpendicular to the sun's rays, its energy utilization efficiency will be greatly increased. For the dish solar system, the tracking accuracy of the positioning device to the position of the sun is the basic premise of its work. [0003] In the current common solar energy system, there are usually two types of methods for driving the positioning device to track the sun (dish condenser or photovoltaic panel...
