Research shows that the power generation capacity of the solar panel is in direct proportion to the received light intensity, and when the solar light intensity and the area of the solar panel are fixed, the power generation capacity of the solar panel is strongest when the solar panel is perpendicular to the incident sunlight. However, the solar panel of the existing photovoltaic power generation device is generally fixedly installed towards a certain specific direction, and most of the time cannot be perpendicular to sunlight in the power generation process due to the continuous change of the azimuth of the sun, sometimes even larger deviation occurs, so that the power generation capacity of the photovoltaic power generation device is greatly affected, and the output power of the power generation device is limited.
For this reason, solar photo-thermal power generation technology is gradually used at home and abroad to generate power. Solar photo-thermal power generation is to collect solar heat energy by utilizing a large-scale array parabolic or butterfly-shaped reflecting mirror, provide steam by a heat exchange device and combine the process of a traditional steam turbine generator, so that the purpose of power generation is achieved. The solar photo-thermal power generation technology is adopted, so that an expensive silicon crystal photoelectric conversion process is avoided, and the cost of solar power generation can be greatly reduced. The solar photo-thermal power generation generally adopts a tower system, which is also called a centralized system. It is a large-scale solar reflector mounted on a large-area field, commonly called heliostat or fixed star mirror, and functions similarly to a fixed star mirror. Each configured with a tracking mechanism to accurately concentrate sunlight reflections onto a receiver at the top of a tall tower. The concentration ratio on the receiver may be over 1000.

When the device is used, the reflector can be driven to swing through the retraction of the piston rod in the pitch angle oil cylinder, so that the pitch angle of the reflector can be adjusted.
However, in the heliostat in the prior art, when the pitching angle of the reflector is gradually increased in the pitching process of the reflector until the gravity center of the reflector is positioned in front of the hinge shaft axis of the hinge seat of the reflector, the reflector receives forward tilting moment under the dead weight, so that the balance of the reflector is poor, eccentric load (tilting load) can be generated on a bearing, a pitch angle oil cylinder and a stand column in the heliostat, and the driving structure for driving the reflector to act to adjust the azimuth angle and the pitch angle and the stand column increase extra load when the heliostat is not in operation; meanwhile, the reflector can form a pulling force on the pitch angle oil cylinder due to gravity, so that the pitch angle oil cylinder generates a negative load, and higher requirements are put on the rigidity of the pitch angle oil cylinder and the precision of the pitch angle oil cylinder.

Detailed Description
Embodiments of the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 6, the tower type photo-thermal power generation system of the present invention includes a centrally located heat collecting tower 1 and a plurality of heliostats 2 arranged around the heat collecting tower 1. Heliostat 2 includes a column 100 and a tracking drive 200 mounted on the upper end of column 100, and further includes a mirror 300 mounted above tracking drive 200, mirror 300 including a mirror frame 31 and a mirror surface 33 mounted on mirror frame 31.
The tracking driving device 200 includes a fixed base 21 fixedly mounted on the upright 100, a turntable 22 is rotatably mounted on the fixed base 21, and the turntable 22 can rotate under the driving of a plurality of azimuth cylinders to adjust the azimuth of the mirror 300, and the specific mode is shown in the patent application CN106575126 a. The turntable 22 is further provided with a structure capable of adjusting the pitching angle of the reflecting mirror 300, the structure comprises a reflecting mirror hinge seat 26 and a pitch angle oil cylinder hinge seat 28 which are fixedly arranged on the turntable 22, the arrangement direction of the reflecting mirror hinge seat 26 and the pitch angle oil cylinder hinge seat 28 is defined to be the front-back direction, the reflecting mirror hinge seat 26 is positioned in front of the pitch angle oil cylinder hinge seat 28, and a reflecting mirror hinge axis 27 of the reflecting mirror hinge seat 26 and a pitch angle oil cylinder hinge axis 29 of the pitch angle oil cylinder hinge seat 28 extend leftwards and rightwards.
As can be seen from fig. 3, the mirror hinge mount 26 is provided at the upper end face edge of the turntable 22, and the pitch cylinder hinge mount 28 is disposed close to the mirror hinge mount 26, and as can be seen from fig. 6, the pitch cylinder hinge axis 29 of the pitch cylinder hinge mount 28 is located on the front side of the axis of the column 100.
The lens holder 31 includes a central tube located at a middle position in the front-rear direction, and a reflector connection lug plate 34 and a pitch angle cylinder connection lug plate 32 are respectively arranged on the central tube and are distributed at a certain angle. The length of the mirror connection ear plate 34 is greater than the length of the pitch cylinder connection ear plate 32, and the hinge end of the pitch cylinder connection ear plate 32 is located on the rear portion of the mirror 300 in the front-rear direction, and the hinge end of the mirror connection ear plate 34 is located on the front portion of the mirror 300 in the front-rear direction.
The pitch angle oil cylinder is hinged on the pitch angle oil cylinder hinge seat 28, the pitch angle oil cylinder comprises a piston rod 25 hinged on the pitch angle oil cylinder hinge seat 28, and further comprises a cylinder body 24 sleeved outside the piston rod 25, wherein one end, close to the pitch angle oil cylinder hinge seat 28, of the cylinder body 24 is hinged on the hinge end of the pitch angle oil cylinder connecting lug plate 32, and the hinge axis is a cylinder body hinge axis 23.
In the present invention, the pitch ram hinge mount 28 is disposed close to the mirror hinge mount 26, and specifically, the distance between the mirror hinge axis 27 and the pitch ram hinge axis 29 is smaller than the distance between the mirror hinge axis 27 and the cylinder hinge axis 23, so that the mirror can be in the position shown in fig. 5 when horizontally placed horizontally, in which the pitch ram hinge axis 29 is located between the mirror hinge axis 27 and the cylinder hinge axis 23 in the front-rear direction. Thus, the pitch cylinder can follow the mirror 300 approximately in parallel when the mirror 300 is driven to pitch.
In the invention, the mirror 300 has a deflection stroke when being driven by the pitch angle cylinder to perform pitching oscillation, and the mirror center of gravity 35 of the mirror 300 is positioned in front of the mirror hinge axis 27 in the deflection stroke, so that when the mirror 300 swings into the deflection stroke, the mirror 300 tends to generate a counterclockwise rotation trend as shown in fig. 6 under the action of dead weight, the mirror 300 tends to be unbalanced in the controlled pitching oscillation, and the difficulty of angle control is increased. In order to partially compensate or completely balance the moment effect, in the invention, through design and selection, a proper pitch angle oil cylinder is selected and corresponding calculation is performed, so that the center of gravity 210 of the pitch angle oil cylinder is always positioned behind the axis of the upright post 100 in the whole pitch swing process of the reflector. According to the above description, the cylinder hinge axis 23 is located on the rear portion of the mirror 300, so that the gravity of the pitch cylinder can generate a clockwise moment effect on the mirror as shown in fig. 6, and the mirror 300 is more easily balanced due to the counterclockwise moment effect of the gravity of the mirror due to the counter-clockwise moment effect of the mirror, which is fully balanced or partially balanced (specifically, which is determined according to the matching and the positional relationship of the pitch cylinder).
When the invention is used, in an initial state, the reflector 300 is horizontally transversely arranged on the tracking driving device 200, and when the pitching angle of the reflector is adjusted, the pitching angle oil cylinder is started to push the cylinder body 24 to extend. As the mirror continues to oscillate, the mirror center of gravity 35 is located in front of the mirror hinge axis 27, i.e. into the yaw stroke. At this time, the counter-clockwise moment of the dead weight of the reflector and the clockwise moment of the gravity of the pitch angle oil cylinder are balanced with each other completely or partially, so that the unbalanced degree of the reflector is reduced. When swinging to the extreme position shown in fig. 6, the pitch cylinder center of gravity 210 is located rearward of the column 100 axis and the mirror center of gravity 35 is located forward of the column 100 axis, reducing the overturning moment on the column and tracking drive when subjected to wind load impact.
In the above embodiment, the mirror hinge seat is disposed at the outer edge of the end face of the turntable, and the pitch angle cylinder hinge seat is disposed at a position close to the center, and in other embodiments, the mirror hinge seat and the pitch angle cylinder hinge seat may be translated simultaneously. According to calculation and analysis, the closer the pitch angle oil cylinder hinging seat is to the reflector hinging seat, the smaller the telescopic stroke of the pitch angle oil cylinder is, and the pitch angle oil cylinder with smaller stroke can be selected.
In the above embodiment, the center of gravity of the cylinder is always kept behind the axis of the upright post, and in other embodiments, the function of balancing the stress of the reflecting mirror can be realized as long as the center of gravity of the pitch angle cylinder is kept behind the hinge axis of the pitch angle cylinder.
In this embodiment, the upright forms the base.
In the specific embodiment of the heliostat of the present invention, the structure of the heliostat is identical to that of the above embodiment, and the details thereof are not repeated.
