Figure 6 , Figure 7 As shown, the bottom of the heat conductive block has an insertion port, and the upper end of the heat collecting pipe is inserted into the insertion port of the heat conductive block. The upper fixing seat and the lower fixing seat are fixed together, and the upper fixing seat and the lower fixing seat jointly form a through hole through which the water circulation pipe passes. The water circulation pipe passes through the upper fixing seat and the lower fixing seat from the through hole. The lower fixing seat is fixed in the manifold shell, and the insulation layer fills the interior of the manifold shell and the insulation layer wraps the water circulation pipe, the upper fixing seat and the lower fixing seat. The hollow manifold shell has an annular cavity, and the manifold liner and the insulation layer are located in the annular cavity. The bottom of the manifold shell is fixed on the manifold base, and the manifold base is also hollow and annular. The manifold base can prevent the manifold shell from rotating. The bottom of the hollow manifold base is provided with a notch through which the heat collecting pipe passes. The upper end of the heat collecting pipe passes through the notch on the manifold base and the manifold shell in turn, and is finally inserted into the insertion port of the heat conductive block.

[0034] Combination Figure 1As shown, the solar thermal power generation device also includes a base and multiple groups of evenly distributed bearing rods. There are three groups of bearing rods, which are evenly distributed along the circumferential direction. The bearing rods include a first bearing rod, a second bearing rod, and a third bearing rod that are integrally formed or non-integrated. That is, the first bearing rod, the second bearing rod, and the third bearing rod can be integrally formed or can be separate components. The base is located below the support seat, the support seat is fixed on the base, one end of the third bearing rod is connected to the base, the other end of the third bearing rod is connected to the support seat, one end of the second bearing rod is connected to the support seat, the other end of the second bearing rod is connected to the junction box base, one end of the first bearing rod is connected to the junction box base, and the other end of the first bearing rod is ball-jointed on the moving platform. If the first bearing rod, the second bearing rod, and the third bearing rod are integrally formed, it can be regarded as that the bearing rod passes through the support seat and the junction box base in sequence. Through the load-bearing rod, the moving platform bears the gravity of the heat collection water header, the heat collection tube, the support seat and the base, and the end of the first load-bearing rod (the upper end of the load-bearing rod) is ball-hinged, that is, the first load-bearing rod and the moving platform can rotate within a certain range.

[0035] Combination Figure 1 , Figure 8 As shown, the solar thermal power generation device also includes a lifting mechanism, an upper end cover and a lower end cover fixed together, an upper retainer and a lower retainer fixed together, and a ball head. The ball head is fixed on the output end of the lifting mechanism, and the spherical upper retainer and the spherical lower retainer are combined to form a spherical cavity. The ball head is placed in the spherical cavity formed by the upper retainer and the lower retainer. A plurality of steel balls are arranged in the upper retainer and the lower retainer. The steel balls of the upper retainer are partially exposed from the upper retainer, and the steel balls of the lower retainer are partially exposed from the lower retainer. The upper retainer and the lower retainer are placed in the spherical groove formed by the upper end cover and the lower end cover. The steel balls are in contact with the inner wall of the spherical groove, the ball head is in contact with the inner wall of the spherical cavity, and the ball head is in contact with the steel balls. The upper end cover is fixed on the moving platform. There are three lifting mechanisms, which are evenly distributed along the circumferential direction. The lifting mechanisms are used to realize the up and down movement of the moving platform and can adjust the inclination angle of the moving platform. When the lifting heights of the three lifting mechanisms are inconsistent, the heights of the ball heads corresponding to the three lifting mechanisms are also inconsistent, which will cause the upper end cover and the lower end cover to rotate within a certain range relative to the retaining frame (upper retaining frame and lower retaining frame), thereby realizing the adjustment of the inclination of the moving platform.

[0036] One way is: the lifting mechanism is a ball screw, and the ball head is fixed on the output end of the ball screw. The ball screw can realize the up and down movement of the moving platform and adjust the inclination.

[0037] Combination Figure 1 , Fig. 9As shown, another way is: the lifting mechanism is a hydraulic cylinder, the hydraulic cylinder includes a cylinder seat, a cylinder barrel fixed on the cylinder seat, a piston rod located in the cylinder barrel, a cylinder cover fixed at the end (upper end) of the cylinder barrel, a guide sleeve fixed in the cylinder barrel, and a piston sleeved and fixed on the piston rod. The solar thermal power generation device also includes a static platform, which is located at the bottom. The cylinder seat is rotatably mounted on the static platform, and of course, the entire hydraulic cylinder can also be kept in a vertical state. The piston rod is located in the cylinder barrel and passes through the cylinder cover. The guide sleeve is used to guide the piston rod. The piston is sleeved on the piston rod, and the piston and the piston rod are fixed. The cylinder barrel is provided with an oil inlet and an oil outlet, and the ball head is fixed to the end of the piston rod. In this way, the up and down movement of the piston rod can realize the up and down movement of the ball head, thereby realizing the up and down movement of the moving platform and adjusting the inclination. The lifting mechanism supports the gravity of the moving platform.

[0038] Combination Figure 1 , Fig. 9 As shown, the solar thermal power generation device also includes a magnetostrictive displacement sensor, a movable magnetic ring, and a connecting frame. The magnetostrictive displacement sensor and the movable magnetic ring belong to the prior art. One end of the magnetostrictive displacement sensor is fixed to the cylinder seat, and the other end of the magnetostrictive displacement sensor is fixed to the cylinder cover. The magnetostrictive displacement sensor is stationary. One end of the connecting frame is fixed to the piston rod, and the other end of the connecting frame is connected to the movable magnetic ring. When the piston rod moves up and down, the movable magnetic ring is driven to move up and down through the connecting frame. The magnetostrictive displacement sensor and the movable magnetic ring are used together to detect the displacement value of the piston rod, so that the position of the piston rod moving up and down can be known.

[0039] A rotary cleaning needle (not shown) is provided at the center of the Fresnel lens. After the solar thermal power generation device has been used for a period of time, dust or fallen leaves will inevitably accumulate on the Fresnel lens, which will affect the light passing through the Fresnel lens.

[0040] The photothermal power generation device is used to generate electricity. In order to realize the power generation function of the photothermal power generation device, the photothermal power generation device also includes a turbine power generation device. The outlet pipe is connected to the turbine power generation device, that is, the outlet pipe is connected to the turbine power generation device, and the steam coming out of the outlet pipe enters the turbine power generation device. The working principle of the photothermal power generation device: the height and inclination of the moving platform are adjusted by the lifting mechanism so that the Fresnel lens is always perpendicular to the sunlight. After passing through the Fresnel lens, the sunlight is focused on the reflector, and then reflected by the reflector to the heat collecting tube. Then the heat collecting tube absorbs the energy of the light and generates heat energy, and then conducts the heat energy to the heat conducting block. The heat conducting block heats the water in the water circulation pipe. When the temperature reaches a certain level, the water evaporates and vaporizes. The steam enters the external turbine power generation equipment from the outlet pipe, driving the turbine to rotate at high speed, thereby driving the power generation device to work and generate a large amount of electricity. The valve in the inlet pipe is opened, and water can be added to the water circulation pipe.

[0041] The solar thermal power generation device also includes a waste heat recovery device, which has at least one input port and at least one output port, and the turbine power generation device has a waste heat port. One input port of the waste heat recovery device is connected to the waste heat port of the turbine power generation device, and one output port of the waste heat recovery device is connected to the inlet pipe. After the steam enters the turbine power generation device, the turbine power generation device will generate waste hot water, which flows through the waste heat recovery device. After the waste heat recovery device recovers and processes the waste hot water, the waste hot water comes out from the output port of the waste heat recovery device and then enters the inlet pipe. The waste hot water flows into the water circulation pipeline through the inlet pipe. Since the waste hot water has a certain temperature, the generation of water vapor is accelerated. That is, the waste heat recovery device will recycle the steam that drives the turbine to rotate at high speed to generate electricity into medium-temperature water (waste hot water), and then send this medium-temperature water to the water collection header, through the water circulation pipeline, to accelerate the water vapor generation process of the solar thermal power generation device, promote the recycling of waste heat of the turbine power generation device, and improve the efficiency of the solar thermal power generation device.

[0042] The control system principle involved in the solar thermal power generation device can be solved by using the existing technology. One control principle is: a solar automatic tracking sensor is installed on the moving platform. The solar automatic tracking sensor senses whether the sunlight is perpendicular to the Fresnel lens plane. When the sunlight is not perpendicular to the Fresnel lens plane, the solar automatic tracking sensor will output a deviation signal, amplify the signal and send it to the controller. The controller controls the hydraulic cylinder to work and adjust the height and inclination of the moving platform to make the sunlight perpendicular to the Fresnel lens plane. The control principle of the hydraulic cylinder is: after receiving the signal, the controller performs a model transformation of spatial motion, performs a reverse solution of the moving platform to solve the required extension of each hydraulic cylinder, and then converts the command signal into an analog quantity to the hydraulic cylinder. At the same time, the extension length of the hydraulic cylinder piston rod can be measured by a magnetostrictive displacement sensor, and fed back to the controller for comparison. The controller controls and adjusts the position of the piston rod of each hydraulic cylinder, so that each hydraulic cylinder coordinates the action to complete the required action. This control principle is not the innovation of the present invention. The solar thermal power generation device of the present invention can also use other control principles of the existing technology to achieve automatic control.

[0043] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
