Description

Technical Field

[0001] This invention pertains to the field of high-efficiency, low-cost solar thermal power generation or heating using dual-axis tracking technology for medium- and high-temperature solar energy. Background Technology

[0002] Currently, solar thermal power generation and heating systems worldwide using parabolic trough or Fresnel collectors suffer from four major problems: first, their photothermal conversion efficiency is too low because they all track the sun on a single axis, wasting a significant amount of sunlight; second, their cost is extremely high; and third, connecting the collectors to the external environment is difficult due to the constant movement of the external interfaces. For example, there are only two types of linear focusing solar thermal power generation: parabolic trough solar thermal power plants, which typically have an annual average photothermal conversion efficiency of 42%, and Fresnel solar thermal power plants, which have an annual average photothermal conversion efficiency of only about 35%, both resulting in high costs for both power generation and heating.

[0003] I previously invented a solar-powered high-temperature generator to solve these problems, but it had the following drawbacks: First, the support frame had to be very thick to improve bending strength, consuming a lot of steel and making it very heavy; second, the "stationary interface" meant that the pipe joints could not be a single point when connecting to external parts, still having a large rotation radius and rotating with the azimuth angle, making external connections inconvenient; third, the vacuum tubes required a special pipe rack for suspension, with long cantilever arms, consuming a lot of steel and being prone to deformation; fourth, the tee pipes had to be made of very long stainless steel corrugated pipes, which greatly increased fluid resistance and cost, especially when the dual shafts oscillated significantly during sunlight, easily damaging the insulation material and being unsightly. Therefore, in the representative first solution of this utility model, namely the rod-type dual-shaft high-efficiency solar-powered high-temperature generator, all these components, as well as the main support rod and diagonal support rod, were eliminated, replaced by multi-functional or more advanced components, making the structure simpler, lighter, and lower in cost, completely eliminating the aforementioned drawbacks of the original solar-powered high-temperature generator. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems and to invent a dual-axis high-efficiency solar thermal generator with extremely high heat collection efficiency, which is cheaper due to its simpler and lighter structure. Although it is a dual-axis solar generator, it can turn the bidirectional motion interface into an absolutely static external interface, which is convenient for heat storage and easy to connect multiple machines into a large group for power generation or heating.

[0005] This utility model is achieved through the following technical solution:

[0006] 1. A dual-axis high-efficiency solar thermal generator, comprising a dual-axis automatic sun-following machine, a concentrator assembly, a collector assembly, a frame assembly, a media piping assembly containing two types of variable-speed transformers, and a driver, characterized in that:

[0007] A. The dual-axis automatic sun-following machine and frame include an azimuth tracking mechanism and an elevation tracking system, as well as a frame, a driver, and a controller. The dual-axis automatic sun-following machine will be referred to as the sun-following machine below.

[0008] (a) The azimuth tracking system includes an azimuth axis frame, a speed transmission component, and a driver. The azimuth axis frame includes an azimuth axis, a base plate, and a spindle that are fixedly connected to each other. The azimuth axis is fixedly installed on the ground plane or platform. The base plate and spindle fixedly connected to its upper end serve as the carrier of the azimuth tracking mechanism composed of the speed transmission component. The base plate is perpendicular to the azimuth axis and connected to it. The spindle is perpendicular to the base plate and connected to it. The driver, i.e., the motor, causes the azimuth tracking mechanism to rotate around the azimuth spindle to track the sun. Its end forms an upper platform that is fixedly connected to the trapezoidal seat of the altitude axis frame, carrying the altitude angle tracking system to rotate around the azimuth axis to track the sun.

[0009] (b) The elevation angle tracking system includes an elevation angle axis, an elevation axis frame, a speed transmission component, and a support lifting mechanism and a driver. The elevation angle axis is referred to as the elevation axis. The upper platform of the trapezoidal seat in the frame serves as the carrier of the elevation axis. The end of the speed transmission component driven by the driver, namely the support lifting mechanism, is connected to the condenser and the solar collector component to drive the condenser and the solar collector to track the sun around the elevation axis in the direction of solar elevation angle.

[0010] (c) The height shaft and its frame components include the height shaft and its support pile, the axle connector, and the trapezoidal seat. The height shaft and its support pile are located on the upper platform of the trapezoidal seat. The upper end of the support pile is connected to the height shaft, and its lower end is fixed to the platform. The axle connector is either a lifting rod type or a lifting beam type. The connection between the pull lens ring and the height shaft in the lifting rod type axle connector is either indirect, that is, the upper end of the lifting rod and the pull lens ring are fixedly connected to each other; the lower end of the lifting rod is fixedly connected to the condenser lens frame; the lower end of the pull lens ring is fixedly connected to the upper end of the support pile; the lower end of the support pile is movably connected to the height shaft; and the height shaft and the support pile are fixedly connected. The connection between the pull lens ring and the height shaft is either direct, that is, the pull lens ring is directly connected to the height shaft without passing through the support pile. Under this condition, the height shaft and the support pile must be movably connected.

[0011] Above the trapezoidal base is a platform, and below it is a base plate. The base plate is a common carrier for the gearbox and synchronous drive shaft or synchronous drive chain of the Japanese machine, as well as the lifting rod and the driver in the height angle direction extending from the gearbox. The controller of the Japanese machine is also located on the trapezoidal base.

[0012] The following text refers to the biaxial high-efficiency solar high-temperature engine with the lifting rod as the axle mirror connector as the rod-type biaxial high-efficiency solar high-temperature engine, and the biaxial high-efficiency solar high-temperature engine with the lifting beam as the axle mirror connector as the beam-type biaxial high-efficiency solar high-temperature engine.

[0013] B. The condenser lens component is a condenser lens that can focus sunlight into a focal line or focal band. A condenser lens component that uses the sun to generate a focal line or focal band is called a condenser lens unit. The condenser lens component may be a framed condenser lens component or a frameless grating condenser lens component.

[0014] The lens frame condenser component includes an upper side rod, a lower bottom beam, a lens back rod, and a lens plate. The lens back rod fixes the upper side rod and the lower bottom beam together to form a lens frame with at least four sides. At least two of the lens back rods are curved, broken, or zigzag lines, and at least one upper side rod and one lower bottom beam are straight lines. The lower bottom beam is also called the bottom center beam. The lens plate is fixedly connected to the lens frame. The grating plate condenser component includes a main grating plate, sub-grating plates, and a lens plate. The main grating plate and multiple sub-grating plates are fixedly connected. The sub-grating plates can be single plates or formed by grating rods and connecting lenses. Both the main grating plate and the sub-grating plates are fixedly connected to the lens plate.

[0015] The dual-axis high-efficiency solar high-heat generator has two condenser lens units, which are installed on both sides of the height axis body, that is, at both ends of the height axis. Each condenser lens unit is connected to its lifting rod or lifting beam. The focal line or focal band center line of the two condenser lens units coincides or nearly coincides with the extension line of the axis center line of the height axis. The two condenser lens units are connected by a lens rod or not.

[0016] The lower end of the lifting rod of the rod-type biaxial high-efficiency solar high-heat generator is either fixedly connected to the frame of the lens condenser or fixedly connected to the main grid plate of the grid condenser. The upper end of each lifting rod is fixedly connected to the lens plate ring.

[0017] The middle or lower part of the condenser lens is connected to a guide rail, which in turn connects to the lifting rod. The guide rail is either fixedly connected to the frame of the condenser lens or directly or indirectly fixedly connected to the main grid plate of the condenser lens. The lifting rod is connected to the speed transmission component of the altitude angle tracking system of the aircraft on one hand, and to the guide rail on the other hand, it is slidably or rollably connected.

[0018] C. The collector component is a collector for a vacuum tube assembly. The vacuum tube assembly includes a vacuum tube and interfaces. The vacuum tube can be either a single-pass or double-pass vacuum tube. Any vacuum tube consists of a cover tube and an inner tube. The cover tube is transparent, and the outer surface of the inner tube has a heat-absorbing material. The space between the cover tube and the inner tube is a vacuum. The inlet and outlet interfaces of the single-pass vacuum tube are at the same end, called the tube head, and the other end is called the tube tail. Therefore, the single-pass vacuum tube is also called a same-end collector tube. At the tube head, the inner tube extends beyond the cover tube, and all interfaces are connected to the inner tube. At the tube head, the cover tube and the inner tube have a sealed, fixed connection. At the tube tail, there are two possibilities: either the cover tube and the inner tube are each sealed and not in direct contact, but... The inner tube is indirectly contacted by a bracket installed on it and the cover tube; or in another case, the cover tube and the inner tube are directly or indirectly contacted through a corrugated pipe to achieve a seal, and the tail end of the inner tube is sealed with a sealing plate; the inner tube of the double-through vacuum tube extends out of the cover tube from both ends, and each end of the extended inner tube is exposed outside the cover tube, which is also called a straight-through vacuum tube; when installing the vacuum tube collector, the center line of the vacuum tube must coincide or nearly coincide with the focal line or focal band center line of the condenser lens; and the center line of the vacuum tube must also coincide or nearly coincide with the extension line of the height axis center line, so that the position of the center line of the vacuum tube is the position where the three center lines meet in a line, and this center line is called the three-in-one line.

[0019] The single-pass vacuum tube is a tube with two openings at both ends inserted into the inner tube, which is thinner than the inner tube. It is called an insert-type vacuum tube. The insert of the insert-type vacuum tube divides the inner tube into two interconnected parts. The outer end of the insert is an interface, which is the inlet interface; there is also an outlet interface that is directly connected to the inner tube. Both the inlet interface and the outlet interface are located at the tube head of the vacuum tube.

[0020] The head and tail of the vacuum tube are connected to two branch pipe piles connected to the bottom beam end of the condenser frame, and its head with two interfaces extends into the height variable valve located on both sides of the trapezoidal base.

[0021] D. A variable-static device is a device that transforms a pipe with a moving interface at one end into a stationary interface at the other. Pipes transporting high-temperature fluids typically have an inlet at one end and an outlet at the other. The principle behind the variable-static device's transformation is that any variable-static device connected to a pipeline changes one end from a moving outlet interface to a stationary outlet interface, and one end from a moving inlet interface to a stationary inlet interface, without changing the "inlet" and "outlet" nature of the pipeline. The variable-static device includes a housing, a clamping clamp, a restraining cylinder, two high-temperature resistant, easily straightened and bent flexible hoses, and insulation material. The housing is hollow. The outer shell, this cavity, consists of at least three plates. Two of them are facing each other, called the end panels of the variable valve. The third is a surrounding plate, which is a curved panel formed by tightly wrapping and connecting the peripheries of the two end panels with a strip-shaped plate. The tightening clamp, also called a ferrule, either passes through the surrounding plate and connects to it, or passes through one of the end panels and connects to it. The tightening clamp can be a single-tube tightening clamp or a double-tube tightening clamp. A double-tube tightening clamp combines one end of each of two flexible tubes located inside the cavity into a bundle and binds them together, thus securing the... The ends of the two hoses are fixed with clamps; there are two single-tube tightening clamps, each clamping one end of a hose to fix it in place; the area near the outer opening of any tightening clamp is called the stationary port of the stabilizer, and near each stationary port is the stationary interface of the hose. The other end of each of the two hoses, after leaving sufficient bending length inside the stabilizer cavity, must enter the constraint cylinder. Before or after entering the constraint cylinder of the stabilizer, each hose forms a moving interface. Therefore, each stabilizer has four interfaces, two of which are moving interfaces and two are stationary interfaces. The moving interfaces are located at the moving ports of the stabilizer, constraining... The area inside the cylinder or near its two ends is called the moving port of the static transformer, and the stationary port is located near the stationary port of the static transformer. The area near the outer opening of the clamp is called the stationary port of the static transformer. The so-called interface is the opening or pipe joint that will be connected to other pipes. In any case, when the two pipes are working inside the constraint cylinder, they will rotate back and forth, pulling the two flexible hoses inside the static transformer to move back and forth. The constraint cylinder is a hollow cylinder. It either passes through one end face of the cavity shell and is fixedly connected to the end panel, or it passes through the shroud surface and is fixedly connected to the shroud plate. The position of the constraint cylinder on the cavity shell is away from the clamp. The outer surface of the cavity shell is completely covered with heat insulation material.

[0022] The variable stationary device is either an azimuth variable stationary device or an altitude variable stationary device. The cavity of the azimuth variable stationary device is directly or indirectly fixedly connected to the absolutely stationary azimuth axis base plate connected to the azimuth axis. The center line of the constraint cylinder of the azimuth variable stationary device must coincide or approximately coincide with the extension line of the center line of the azimuth axis. Therefore, it is located near the middle of the altitude axis of the aircraft. The altitude variable stationary device is fixedly connected to the trapezoidal base of the aircraft. The center line of the constraint cylinder of the altitude variable stationary device must coincide or approximately coincide with the extension line of the center line of the altitude axis. Therefore, there are two altitude variable stationary devices, located on the two sides of the trapezoidal base near the two ends of the altitude axis. The altitude variable stationary device is simply referred to as the altitude variable.

[0023] E. The medium pipeline component is a pipeline component containing three variable stabilizers. The pipeline component containing three variable stabilizers includes an azimuth variable stabilizer, two height variable stabilizers, two vacuum tubes and a total of four interfaces, as well as connecting pipes.

[0024] The piping component is a component that connects two vacuum tube components outside the two ends of the height axis, and connects them to the outlet pipe and inlet pipe from outside the machine. The two vacuum tubes are either connected in series or in parallel.

[0025] Regarding connecting pipes, let's clarify two concepts: In series piping, the connecting pipe between the left and right high-voltage transformers is called the connecting pipe, and the connecting pipe between the high-voltage transformer and the azimuth transformer is called the extension pipe; in parallel piping, both the connecting pipe and the extension pipe are replaced by a single tee pipe.

[0026] The following conventions apply: When a person is facing the height axis, the left side of the person is called the left end of the height axis; the right side of the person is called the right end of the height axis; the vacuum tube and high-voltage converter outside the left end of the height axis are called the left vacuum tube and left high-voltage converter, and the vacuum tube and high-voltage converter outside the right end of the height axis are called the right vacuum tube and right high-voltage converter.

[0027] In simple terms, the so-called series connection involves placing a connecting pipe horizontally on a trapezoidal base. Its two ends are connected to the left static outlet of the left high-voltage transformer and the right static inlet of the right high-voltage transformer, respectively. Then, an extension pipe is used to connect the left static inlet of the left high-voltage transformer to one of the moving interfaces of the azimuth transformer. Another extension pipe is used to connect the right static outlet of the right high-voltage transformer to the other moving interface of the azimuth transformer. The static outlet and static inlet of the left high-voltage transformer are connected to its moving interface, and the left outlet and left inlet of the left vacuum tube head are respectively transformed through the left high-voltage transformer. Similarly, the static inlet and static outlet of the right high-voltage transformer are respectively transformed through the right inlet and right outlet of the right vacuum tube head, which are connected to its moving interface.

[0028] The above describes connecting the left static outlet and the right static inlet with a connecting pipe. The reverse is also true: connect the left static inlet and the right static outlet with a connecting pipe, and then connect the left static outlet and the right static inlet to the two moving ports of the azimuth converter via two extension pipes. The left static outlet and left static inlet are formed by the outlet and inlet ports of the left vacuum tube head connected to the moving port of the left high-voltage converter, respectively. The right static inlet and right static outlet are formed by the inlet and outlet ports of the right vacuum tube head connected to the moving port of the right high-voltage converter, respectively. This is the second type of series piping.

[0029] The detailed connection process is as follows: Connect the inlet and outlet ports of the left vacuum tube head to the two moving ports of the left high-voltage converter respectively. After passing through the left high-voltage converter, two stationary ports that do not rotate around the height axis are formed. One is called the left stationary inlet port and the other is called the left stationary outlet port.

[0030] Connect the inlet and outlet ports of the right vacuum tube head to the two moving ports of the right high-voltage transformer. After passing through the right high-voltage transformer, two stationary ports are formed, one called the right stationary inlet port and the other called the right stationary outlet port.

[0031] A connecting pipe is placed horizontally on the trapezoidal platform. Its left port is connected to the left static inlet interface of the left high-voltage transformer. Since it is connected in series, the right port of this connecting pipe must be connected to the right static outlet interface of the right high-voltage transformer. The remaining static outlet interface on the left high-voltage transformer is the left static outlet interface. It is connected to the moving interface of the azimuth transformer through an extension pipe. After passing through the azimuth transformer, it becomes a fully static outlet interface. It is called a "fully static outlet interface" because it does not rotate around the height axis or the azimuth axis.

[0032] The remaining part is the right static inlet port on the right high-voltage transformer. This port also connects to the remaining dynamic port of the azimuth transformer via an extension pipe. After passing through the azimuth transformer, it becomes a fully static inlet port because it is formed by extending the right static inlet port of the right high-voltage transformer. This is the first series pipeline connection method. The second series connection method will be discussed below:

[0033] Conversely, the same applies. Connecting the left end of a connecting pipe to the left static outlet port, since it is a series connection, the right end of the connecting pipe must be connected to the right static inlet port. The remaining port outside the left end of the height axis is the left static inlet port, which is connected to one end of the extension pipe. The other end of the extension pipe is connected to the moving port of the azimuth variable valve, and after passing through the azimuth variable valve, it becomes a fully static inlet port. The remaining right static outlet port outside the right end of the height axis is connected to one end of another extension pipe. The other end of the extension pipe is connected to the remaining moving port of the azimuth variable valve, and after passing through the azimuth variable valve, it becomes a fully static outlet port. This is the second type of series pipe connection.

[0034] 2. The parallel piping assembly containing three static control devices includes the inlet and outlet ports of the left vacuum tube and the right vacuum tube outside both ends of the altitude axis, a left altitude converter, a right altitude converter, an absolutely stationary azimuth converter located in the middle of the azimuth-following machine, and two T-junctions. The altitude static control device replaces the constraint cylinder within the static control device with an inner tube head with an interface on the vacuum tube. The moving interfaces of the two flexible hoses inside the altitude converter are respectively connected to the inlet and outlet ports of the vacuum tube head. The hose connected to the inlet port is called the inlet hose, and the hose connected to the outlet port is called the outlet hose. These two hoses extend beyond the clamping clamp, becoming two stationary interfaces that do not move with the altitude angle. One of these interfaces, formed by the left altitude converter, is called the left stationary inlet interface, and the other is called the left stationary outlet interface. The right high-voltage transformer becomes a right static inlet interface and a right static outlet interface. A three-way pipe is placed horizontally on the trapezoidal base platform, with its left port connected to the left static inlet interface, its right port connected to the right static inlet interface, and its third port connected to the moving interface of the azimuth transformer. After exiting the azimuth transformer, it becomes the fully static inlet interface, because it is connected to the two inlets of the left and right vacuum tube heads. Another three-way pipe is also placed horizontally on the trapezoidal base platform, with its left port connected to the left static outlet interface, its right port connected to the right static outlet interface, and its third port connected to the remaining moving interface of the azimuth transformer. After exiting the azimuth transformer, it becomes the fully static outlet interface, because it is connected to the two outlets of the left and right vacuum tube heads.

[0035] 3. The two ends of the lifting beam of the beam-type biaxial high-efficiency solar high-heat generator are either connected to the frames of the two mirror-frame condenser units or directly or indirectly connected to the main grid plate of the two grid plate condenser units. The middle section of the lifting beam is fixedly connected to the upper end of the support beam pile, and the lower part of the support beam pile is movably connected to the height axis.

[0047] exist Figure 1 In the diagram, 1 represents the azimuth axis, and 2 represents the altitude angle of the tracking system. There are two gearboxes on either side of the trapezoidal base 23. One of these gearboxes contains a gearbox, a drive motor, and a controller. The gearbox inside the gearbox 2 drives the lifting rods 3 on both sides via a synchronous shaft 30. The lifting rods 3 slide in the grooves of the guide rail 5 via pins 28. The guide rail 5 is fixedly connected to the condenser lens frame, i.e., the main grid plate 6. Therefore, the raising or lowering of the lifting rods causes the condenser lens to rotate along the altitude axis 16, tracking the sun in the altitude angle direction. Because the gearboxes on both sides are connected to the synchronous shaft 30, the raising or lowering speed and starting or stopping time of the lifting rods 3 on both sides are completely synchronized. Figure 1 4 is the anti-rotation groove of the lifting rod, i.e., the screw 3. It engages with the protrusion (which has been covered) fixed on the base plate 31, allowing it to move up and down but not rotate. 5 is the guide rail, which is indirectly fixedly connected to the main grid plate 6. 7 is the screw. 8 is the grid rod of the sub-grid plate, one end of which is fixedly connected to the connecting lens 9, and the other end is fixedly connected to the main grid plate 6. 10 is the condensing mirror plate. 11 is the heat collection tube, i.e., the vacuum tube, both ends of which are connected to the branch pipe pile 26. The lower part of the branch pipe pile 26 is indirectly connected to the main grid plate 6, and its upper end is connected to the heat collection tube 11. 12 is a lifting rod, the lower end of which is directly or indirectly connected to the main shelf 6, and the upper end of which is fixedly connected to the lens pull ring 17; the lens pull ring 17 belongs to the height axis frame, which is connected to the support ring pile 15 and the cross link 18. The lower part of the support ring pile 15 is movably connected to the height axis 16, and the cross link 18 and the support ring pile 15 form a square seat for the lens pull ring 17.

[0048] Figure 1Part number 14 is a high-voltage inverter, with one installed on the left and one on the right side of the trapezoidal base 23. The one on the left is called the left high-voltage inverter, and the one on the right is called the right high-voltage inverter. They are installed symmetrically on both sides of the trapezoidal base 23. The side of each high-voltage inverter closest to the collector tube 11 is the moving port of the high-voltage inverter. The tube ends of the inlet and outlet interfaces of each collector tube are inserted into the corresponding high-voltage inverter and connected to the two moving interfaces inside the high-voltage inverter. Each high-voltage inverter has two static interfaces on its static port, one upper and one lower as shown in part number 14. The one connected to the inlet interface of the left collector tube head is called the left static inlet interface, and the one connected to its outlet interface is called the left static outlet interface; the one connected to the outlet interface of the right collector tube head is called the right static outlet interface. The one connected to its inlet is called the right static inlet interface.

[0049] The connection method of the series pipeline of the left and right heat collection tubes is as follows: a connecting pipe 13 is used. If its left end is connected to the left static outlet interface, then its right end must be connected to the right static inlet interface. This connecting pipe becomes the inlet and outlet connecting pipe. The remaining left static inlet interface on the left high-voltage transformer is connected to one end of an extension pipe 13'. The other end of the extension pipe 13' is connected to a dynamic interface of the azimuth transformer. All static interfaces on the static port of the azimuth transformer that are connected to the left static inlet interface are called static inlet interfaces.

[0050] The remaining right static outlet port on the right high-voltage transformer is also connected to the azimuth transformer via an extension pipe. Therefore, the other fully static port of the azimuth transformer becomes the fully static outlet port. This is the first series piping connection method. The second series connection method is as follows:

[0051] Conversely, the same applies: first connect a connecting pipe 13 to the left static inlet port on the left, and simultaneously connect it to the right static outlet port on the right. This connecting pipe then becomes the inlet and outlet connecting pipe. On the other hand, connect the azimuth converter to the left static outlet port on the left via the extension pipe 13'. After exiting the azimuth converter, it becomes a fully static outlet port, such as... Figure 2 One of the parts number 32. On the other hand, connect the azimuth converter to the right static inlet port on the right side via another extension pipe (the extension pipe symmetrical to part number 13' on the left). After exiting the azimuth converter, you will find the full static inlet port, such as... Figure 2 The other one of part number 32 shown. This also forms a series connection between the two vacuum tubes.

[0052] exist Figure 1 In the diagram, 19 is an azimuth variable stationary element, whose housing is connected to the absolutely stationary azimuth axis base plate. Its detailed structure can be found in [link to diagram]. Figure 10 and 1120 is a support pile, its upper end connected to the height shaft 16, and its lower end connected to the trapezoidal seat platform. 21 is the power output turntable of the azimuth tracking mechanism, which is fixedly connected to the trapezoidal seat and is connected to the azimuth angle speed change transmission component. 22 is the housing of the azimuth angle speed change transmission mechanism. 23 is the trapezoidal seat, which is called the platform on top and connected to the base plate 31 below. 24 is the fixed support plate of the height variable stationary device, one on each side of the trapezoidal seat, and its root is connected to the trapezoidal seat 23. 25 is the pile seat rod of the support pipe pile 26, on which the support pipe pile 26 of the vacuum tube is fixedly connected. The two ends of the pile seat rod 25 are connected to the front and rear main grid plates. 27 is the U-shaped clamping plate of the lifting rod 3, which clamps the guide rail 5 through the pin 28 and is movably connected to the guide rail; it is the end of the lifting rod 3. 29 is the support pile of synchronous shaft 30, and 31 is the base plate of trapezoidal seat. It is the common carrier of synchronous shaft 30, transmission gearbox and lifting rod.

Figure 2 In the diagram, 13' is the extension pipe connecting the right high-voltage transformer and the azimuth transformer; 13 is the connecting pipe connecting the left and right high-voltage transformers; and 32 are two fully static interfaces coming from the azimuth transformer 19. The remaining part numbers and... Figure 1 Those with the same name in China have the same meaning.

Figure 3 In this diagram, 33 is the glass cover tube of the single-pass vacuum tube, 34 is the vacuum interlayer between the cover tube 33 and the inner tube 32, and 35 is the inner thin tube of the single-pass vacuum tube, also called a sleeve-type vacuum tube. This inner thin tube 35 divides the inner tube 32 into two interconnected parts. The interface of the thin tube 35 that protrudes outside the inner tube is the inlet interface, and the other interface at the head of the inner tube is the outlet interface. There can be one or two outlet interfaces. If there are two outlet interfaces, these two interfaces are connected to the two ports of a three-way pipe. The third port of this three-way pipe constitutes the unique total outlet interface. Part number 36, connected to the left and right sides of the vacuum tube head, are the inlet and outlet interfaces. 40 are two flexible hoses that bend inside the height variable static device 14. The external insulation material and end panel of the variable static device 14 have been removed to facilitate the display of the internal conditions. 37 is the clamp that connects the heat collection tube to the branch pipe pile 26, and 38 is the clamp of the height variable static device 14, i.e., the outlet, also called the static port.

[0060] Figure 7 This is a front view of a biaxial high-efficiency solar thermal generator with a vertical lifting beam. In the diagram, 1 is the azimuth axis, 2 is the transmission gearbox of the altitude angle tracking system (one on each side), 3 is the lifting rod, 4 is the anti-rotation groove for the lifting rod (screw), 5 is the guide rail fixedly connected to the bottom beam 6 of the mirror frame, which is movably connected to the U-shaped clamp at the end of the lifting rod via pin 27, 6 is the bottom beam of the condenser lens, 7 is the branch pipe pile of the vacuum tube 11, its root is fixedly connected to the bottom beam 6 of the mirror frame, and its upper part is connected to the vacuum tube 11, 8 is the mirror back rod, its upper end is connected to the upper side rod 9 of the condenser lens, and its lower part is connected to the bottom beam 6, 10 is the mirror plate, 11 is the heat collection tube, 12 is the diagonal tie rod connecting the end of the vertical lifting beam 17 to the upper side rod of the mirror frame, and 13 is two T-pipes, which are placed horizontally on the trapezoidal seat 23.

Figure 5The same in all of them are in parallel connection, that is, the two connect the left static outlet interface and the right static outlet interface, and connect the left static inlet interface and the right static inlet interface.

[0062] As mentioned above, Figure 8 The pipe connections in the system are in parallel, and Figure 5 The same. Further details are as follows: In Figure 8 In section 13, there are two tee pipes. If the left port of one tee pipe is connected to the left static inlet, its right port must be connected to the right static inlet; similarly, the left port of the other tee pipe must be connected to the left static outlet, and its right port must be connected to the right static outlet. The third port of each tee pipe is connected to the two moving ports of the azimuth converter. On the static port of the azimuth converter, one becomes a fully static inlet port, and the other becomes a fully static outlet port. The fully static inlet port is connected to the inlet ports of the left and right vacuum tubes, and the fully static outlet port is connected to the outlet ports of the left and right vacuum tubes, respectively. This is because the left static inlet and outlet ports are connected to the inlet and outlet of the left vacuum tube head located on the moving port of the left high-voltage converter, and the right static inlet and outlet ports are connected to the inlet and outlet of the vacuum tube head located on the moving port of the right high-voltage converter, respectively.

In Figure 9 In this structure, 31 is the inner tube of the vacuum tube, 32 is the glass cover tube of the vacuum tube, and 33 are two flexible hoses inside the height stabilizer. One end of each hose connects to an interface 36 of the vacuum tube, and the other end exits from the clamping clamp 38 of the stabilizer. This stabilizer has two clamping clamps, i.e., two static outlets. 34 is the vacuum jacket, and 35 is a thin tube inserted into the inner tube, dividing it into two interconnected parts. Each of these parts has an external interface 36 at its end, which connects to the two flexible hoses 33 inside the stabilizer. 37 is a clamping clamp that fixes the inner tube end to the branch pipe pile 7. 39 is the guide groove of the guide rail, in which the pin 27 moves. The remaining part numbers and... Figure 7 Those with the same name in China have the same meaning.

[0064] Figure 10 This is a front view of the azimuth converter. In the diagram, 1 represents two flexible hoses on the converter's inlet, and 2 represents a bundle of insulating material emerging from the opening of the converter's clamping clamp 3 (also called a throwing clamp). Inside the converter, these two flexible hoses move separately, and their movement is as follows... Figure 11 As shown in 1′, because neither of them requires insulation material inside the cavity shell 5, they can move freely and the tube length is very short. Insulating material typically needs to be 10 cm thick; if wrapped around a metal corrugated pipe, its diameter becomes over 20 cm, making bending very difficult. 4 is the fixed connecting plate for connection to the outside world; it is welded to the end 5 of the cavity shell. The cavity shell 5 is a hollow shell formed by two facing plates and a strip-shaped plate surrounding these two plates, connected together. Figure 11 As can be seen, the shape of this cavity shell is somewhat similar to that of a drum used for striking gongs and drums. 6 is the insulation material, completely surrounding the cavity shell; 7 is the variable-static body; 8 is the tube bundle package near the constraint cylinder; 9 is the bending hoop, its lower part rooted in the trapezoidal base platform 12 of the machine. It and the constraint cylinder (see...) Figure 11 The tube bundle is bent at 90° to allow it to rotate back and forth within the confinement cylinder. 10 is the external rigid tube, and 11 is the connecting clamp, which connects the external rigid tube 10 and the flexible tube 1″.

[0065] Figure 11 yes Figure 10 The BB sectional view. In the figure, part number 1′ represents the state of the two hoses in the moving section of the variable stationary device. 15 is the constraint tube, which is connected to the cavity shell. Its centerline coincides with or is approximately coincident with the extension of the azimuth axis. Therefore, this hose 1″ does not translate in the constraint tube, but can only reciprocate in the constraint tube to track the sun with the azimuth angle. 8 is the insulation material, and 16 is the screw.

[0066] The height variable static device is similar; just put... Figure 11Replace the constraint cylinder 15 with the inner tube head of the vacuum tube, and connect the right ends 1″ of the two flexible tubes to the inlet and outlet ports of the vacuum tube head respectively. Because the centerline of the vacuum tube originally coincides with the extension of the height axis, and the height variable stationary device does not require the bending clamp 9 and the trapezoidal seat platform 12. The two types of variable stationary devices are otherwise the same. The height variable stationary device is abbreviated as height converter.

[0067] More embodiments can be listed for this utility model, all of which fall within the scope of protection of the claims of this utility model.

[0068] The advantages of this utility model are:

[0069] 1. This utility model uses a variety of simple and lightweight dual-axis solar focusing solar collectors to replace the current inefficient and high-cost single-axis solar focusing solar collectors of the trough and Fresnel types, thereby significantly reducing costs.

[0070] 2. Because two types of static converters were invented, the original solar thermal generator's "stationary interface" with no translation but slight rotation was eliminated. This utility model improves upon it, transforming the bidirectional large-motion interface in both azimuth and elevation directions into a completely stationary external interface. This allows the heated working fluid to be transported outward without dynamic sealing pipe joints, which is both safe and convenient. It completely eliminates the problem in the prior art where dynamic sealing sometimes causes leakage of the working fluid's heat transfer oil, resulting in fires (for example, fire accidents sometimes occur in today's parabolic trough solar thermal power plants due to the presence of dynamic sealing).

[0071] The invention of the static variator will completely solve the world problem that has persisted for nearly 60 years: although dual-axis solar thermal and solar-electric conversion machines have the highest solar thermal and solar-electric conversion efficiency, they cannot store heat on the ground due to the large fluctuations caused by dual-axis solar thermal power generation. As a result, there are not a single dual-axis solar thermal power plant among the three or four hundred solar thermal power plants in the world.

[0072] 3. A simple and lightweight lifting frame was invented to replace the original solar high-temperature machine's carrying rack. To increase bending strength, the carrying rack required welding many steel rods and plates, which was cumbersome and increased costs. Since the tensile strength of steel is much greater than its bending strength, the lifting frame is lightweight and significantly reduces costs.

[0073] 4. This invention overcomes the shortcomings of current trough-type and Fresnel-type solar collectors, which suffer from significantly increased cosine losses in high-latitude regions, making them unsuitable for use in areas with a latitude of 40° or higher. Because this invention is a dual-axis solar collector, the angle of incidence of sunlight on the opening of the concentrator lens is always zero, resulting in no cosine loss. Therefore, its application area is greatly expanded.

[0074] 5. Because of the invention of the static variator, it is convenient to output the heated working fluid, so it is easy to store heat on a large scale underground and retain heat for a long time. This is very important for solar energy to supply heat to the outside world or for solar thermal power generation.

[0075] 6. The rod-type twin-shaft high-efficiency solar thermal generator eliminates the T-junction pipe used in the original solar thermal generator, reducing both cost and fluid flow resistance. Because the T-junction pipe constantly oscillates with the elevation angle, a very long stainless steel corrugated pipe is required, increasing both fluid resistance and cost. The second solution of this invention, the parallel pipe connection, and subsequent solutions, although also using a T-junction pipe, contain a height stabilizer, preventing the T-junction pipe from oscillating. Therefore, a rigid pipe can be used instead of a corrugated pipe, saving cost, preventing damage to the insulation material, and minimizing fluid resistance.

[0076] 7. The original solar high-heat generator required a long cantilever pipe rack, which was prone to deformation and required a lot of steel. Instead, the collector tubes were installed on the bottom beam of the concentrator or on the height variable element. This is a dual-purpose device that saves steel and reduces costs, and is also safe.

[0077] 8. Many components used in the original Sunshine high-temperature generator, such as the positive support rod and the diagonal support rod, have been eliminated, reducing costs and weight while increasing aesthetics.

A condenser component that generates a focal line or a focal band with the sun is called a condenser unit. The condenser component is either a frame condenser component or a grid condenser component without a frame; The frame condenser component includes an upper edge rod, a lower bottom beam, a mirror back rod, and a mirror plate. The mirror back rod fixedly connects the upper edge rod and the lower bottom beam to form a frame containing at least four edges. At least two of the mirror back rods are curved lines, broken lines, or zigzag lines. At least one of the upper edge rods and one of the lower bottom beams are straight lines.

C. The collector component is a collector of vacuum tube components, which includes a vacuum tube and an interface, the vacuum tube is a single-pass vacuum tube or a double-pass vacuum tube, any vacuum tube is composed of a cover tube and an inner tube, the cover tube is transparent, the outer surface of the inner tube has a heat-absorbing material, and the interlayer between the cover tube and the inner tube is vacuum. The inlet interface and the outlet interface of the single-pass vacuum tube are located at the same end, which is called the tube head, and the other end is called the tube tail, so the single-pass vacuum tube is also called a same-end collector tube. In the tube head, the inner tube extends out of the cover tube, all interfaces are connected to the inner tube, and the cover tube and the inner tube have a sealing and fixed connection in the tube head. There are two cases in the tube tail: either the cover tube and the inner tube are sealed and not in direct contact, but are indirectly contacted through the bracket on the inner tube and the cover tube; or another case is that the cover tube and the inner tube are in direct or indirect contact through the corrugated tube and are sealed, and the inner tube tail end has a sealing plate to block it. The inner tube of the double-pass vacuum tube extends out of the cover tube from both ends of the cover tube, and each end of the extended inner tube is exposed outside the cover tube, which is also called a straight-through vacuum tube. The vacuum tube collector must have the center line of the vacuum tube coincide or approximately coincide with the focal line or the center line of the focal band of the light collector during installation. And the center line of the vacuum tube also coincides or approximately coincides with the extension line of the height axis center line, so that the position of the vacuum tube center line is the position where the three center lines coincide, which is called the three-in-one line. The single-pass vacuum tube is a tube inserted into the inner tube, called an inserted tube vacuum tube, which divides the inner tube into two parts connected to each other. The outer end of the inserted tube is an interface, which is the inlet interface. There is also an outlet interface directly connected to the inner tube. The inlet and outlet interfaces are located at the tube head of the vacuum tube. The tube head and the tube tail of the vacuum tube are connected to the two branch pipes of the lower beam end of the light collector frame, respectively. The tube head with two interfaces extends into the height variable stabilizer inside the trapezoidal seat. D, the so-called static converter is a device that changes one end of a pipe with a dynamic interface into another end with a static interface. The pipe transports high-temperature fluid and has one end as an inlet and the other end as an outlet. However, the dynamic-static rule of the static converter is that any static converter connected in the pipeline changes one end of the dynamic outlet interface into the other end of the static outlet interface. It changes one end of the dynamic inlet interface into the other end of the static inlet interface, without changing the nature of "in" and "out" in the pipeline. The static converter includes a cavity shell, a tightening hoop, a restraining cylinder, two flexible hoses that can withstand high temperatures and are easy to straighten and bend, and a heat insulation material. The cavity shell is a hollow shell composed of at least three plates. Two of the plates are face-to-face plates, which are called end plates of the static converter. The third plate is a girdle plate formed by wrapping the periphery of the two end plates with a band-shaped plate and connecting the two peripheries. The tightening hoop, also known as a tightening hoop, is connected to the girdle plate or an end plate. The tightening hoop can be a single pipe tightening hoop or a double pipe tightening hoop. The double pipe tightening hoop combines the two ends of the two hoses inside the cavity shell into a pipe bundle and bundles them together to fix the ends of the two hoses. The single pipe tightening hoop has two tightening hoops, each of which bundles one end of a hose to fix it. The area near the outer port of any tightening hoop is called the static port of the static converter. Near each static port, there is a static interface of the hose. The other end of each hose has sufficient bending length inside the cavity shell of the static converter and enters the restraining cylinder. Before or after entering the restraining cylinder of the static converter, each end forms a dynamic interface. Therefore, each static converter has four interfaces, two of which are dynamic interfaces and the other two are static interfaces. The dynamic interfaces are located at the dynamic ports of the static converter, which are inside the restraining cylinder or near its two ports. The static interfaces are located at the static ports of the static converter, which are near the outer ports of the tightening hoops. An interface is a port or a pipe joint that connects to other pipes. In any case, two pipes work reciprocally and rotationally in the restraining cylinder, pulling the two hoses in the static converter to move reciprocally. The restraining cylinder is a hollow cylinder that is fixedly connected to an end plate of the cavity shell or a girdle plate. The restraining cylinder is located away from the tightening hoop in the cavity shell. The outer surface of the cavity shell is wrapped with heat insulation material. The azimuth variator or the height variator, the cavity shell of the azimuth variator is directly or indirectly fixedly connected with the absolute stationary azimuth shaft base plate connected with the azimuth shaft; the center line of the constraint cylinder of the azimuth variator must coincide or approximately coincide with the extension line of the center line of the azimuth shaft; therefore it is located near the middle of the sun tracking machine height shaft; the height variator is fixedly connected with the trapezoidal seat of the sun tracking machine, the center line of the constraint cylinder of the height variator must coincide or approximately coincide with the extension line of the center line of the height shaft, therefore the height variator has two, which are located near the two sides of the trapezoidal seat at the two ends of the height shaft; the height variator is also called height variator; E, the medium pipeline component is a pipeline component containing three variators, the pipeline component containing three variators includes an azimuth variator, two height variators, two vacuum tubes and four interfaces, and a connecting pipeline; The pipeline component is a component for connecting the two vacuum tube components outside the two ends of the height shaft in series or in parallel, and connecting the outlet pipe and the inlet pipe from the machine to the pipeline component; Regarding the connecting pipeline, two concepts are first clarified: in the series pipeline, the connecting pipeline between the left and right height variators is called a connecting pipe, and the connecting pipeline between the height variator and the azimuth variator is called an extension pipe; in the parallel pipeline, the connecting pipe and the extension pipe are replaced by a three-way pipe; The following conventions are agreed upon: when a person faces the height shaft and observes, the left side of the person is called the left end of the height shaft; the right side of the person is called the right end of the height shaft; the vacuum tube and the height variator outside the left end of the height shaft are called the left vacuum tube and the left height variator, and the vacuum tube and the height variator outside the right end of the height shaft are called the right vacuum tube and the right height variator; In simple terms, series means placing a connecting pipe horizontally on the trapezoidal seat, with its two ends connecting the left static outlet interface of the left height variator and the right static inlet interface of the right height variator, then connecting the left static inlet interface of the left height variator and one of the movable interfaces of the azimuth variator with an extension pipe, and connecting the right static outlet interface of the right height variator and the other movable interface of the azimuth variator with another extension pipe; the static outlet and static inlet interfaces of the left height variator are connected to the movable interfaces, and the left outlet and left inlet interfaces of the left vacuum tube head are changed through the left height variator; Similarly, the static inlet and static outlet interfaces of the right height variator are connected to the movable interfaces, and the right inlet and right outlet interfaces of the right vacuum tube head are changed through the right height variator; The above describes the connecting pipe connecting the left static outlet and right static inlet interfaces, and the reverse is also true, that is, a connecting pipe is used to connect the left static inlet and right static outlet interfaces, and then the left static outlet and right static inlet interfaces are connected to the two movable interfaces of the azimuth variator through two extension pipes; the left static outlet and left static inlet interfaces are the outlet and inlet interfaces of the left vacuum tube head connected to the movable interfaces of the left height variator, and the right static inlet and right static outlet interfaces are the inlet and outlet interfaces of the right vacuum tube head connected to the movable interfaces of the right height variator; this is the second series pipeline; Detailed connection process is: the left vacuum pipe head import and export two interfaces are connected with the left high variable two dynamic interfaces, through the left high variable, two static interfaces are formed, one is called left static import interface, the other is called left static export interface; The import and export interfaces of the right vacuum pipe head are connected with the two dynamic interfaces of the right high variable respectively, and two static interfaces are formed after passing through the right high variable, one is called right static import interface, and the other is called right static export interface; A communication pipe is transversely arranged on the trapezoidal seat platform, the left port of which is connected with the left static import interface of the left high variable or the left static export interface, because it is in series, so the right port of the communication pipe must be connected with the right static export interface of the right high variable; The left static export interface of the left high variable is left, which is connected with the dynamic interface of the azimuth variable static device through an extension pipe, and becomes a full static export interface after passing through the azimuth variable static device, because it is the left static export interface of the left high variable after extension, so it is called "full static export interface", because it does not rotate around the height axis and the azimuth axis; The remaining right static import interface of the right high variable static port is connected with the remaining dynamic interface of the azimuth variable static device through an extension pipe, and becomes a full static import interface after passing through the azimuth variable static device, because it is the right static import interface of the right high variable after extension; This is the first series connection mode; The second series connection mode is as follows: On the contrary, it is also the same, that is, the left end of a communication pipe is connected with the left static export interface, because it is in series, so the right end of the communication pipe must be connected with the right static import interface; The left static import interface left outside the height axis is connected with one end of the extension pipe, the other end of the extension pipe is connected with the dynamic interface of the azimuth variable static device, and becomes a full static import interface after passing through the azimuth variable static device; The right static export interface left outside the height axis is connected with one end of another extension pipe, and the other end of the extension pipe is connected with the remaining dynamic interface of the azimuth variable static device, and becomes a full static export interface after passing through the azimuth variable static device, which is the second series connection mode.
