Description

Simple and efficient sunlight high heat machine TECHNICAL FIELD

[0001] The present application belongs to the field of high-efficiency and low-cost medium-high temperature solar thermal power generation or heating with double-axis tracking. BACKGROUND

[0002] Now the solar thermal power generation or heating in the world uses trough or Fresnel type heat collecting equipment, which has four big problems, one is that the light and heat conversion efficiency is too low, because they are all single-axis tracking sun, which wastes a lot of sunlight; two is that the cost is very high, three is that the heat collector is difficult to connect with the outside world, because the external interface is constantly moving. For example, there are only two ways of linear focusing light and heat generation, one is trough type light and heat power station, and the annual average light and heat conversion efficiency is generally 42%, the other is Fresnel type light and heat power station, and the annual average light and heat conversion efficiency is only about 35%, and the cost of power generation and heating is very high.

[0003] The inventor of the present application has invented a sunlight high heat machine (patent number ZL 202020749480.2) to solve these problems, but there are the following shortcomings: one is that the carrier must be made very thick in order to improve the bending strength, which consumes a lot of steel and is very heavy; two is that the "fixed interface" made is not a point when connecting with the outside world, but still has a large rotating radius, which rotates with the azimuth angle, and is still not convenient for external connection; three is that the vacuum tube needs to be suspended by a special pipe support, the cantilever is very long, consumes a lot of steel, and is easy to deform; four is that the three-way pipe must be a very long stainless steel corrugated pipe, which has a large resistance to fluid and a high cost, especially when the double-axis follows the sun, the swing is large, the heat preservation material is easy to break, and the appearance is not beautiful. Therefore, in the first representative scheme of the present application, i.e. the rod type simple sunlight high heat machine, all these parts are removed, and the vertical and inclined supporting rods are also removed, and are replaced by one part with multiple functions or more advanced parts, so that the structure is simpler and lighter, the cost is lower, and the above-mentioned shortcomings of the original sunlight high heat machine are completely eliminated. SUMMARY

[0004] The present application is to solve the above problems, to invent a simple and efficient sunlight high heat machine with extremely high heat collecting efficiency, simpler and lighter structure, lower cost, and double-axis tracking sun, but can change the two-way movement interface into an absolutely static external interface, which is convenient for heat storage and connection of multiple machines into a large group for power generation or heating.

[0018] C, the collector component is a collector of vacuum tube components, the vacuum tube components include vacuum tubes and interfaces, the vacuum tubes are single-pass vacuum tubes or double-pass vacuum tubes, 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 is provided with 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 a tube head, and the other end is called a tube tail, so the single-pass vacuum tube is also called a same-end collector tube; on the tube head, the inner tube extends out of the cover tube, all interfaces are connected with the inner tube, and the cover tube and the inner tube are sealingly and fixedly connected on the tube head; on the tube tail, there are two cases: or the cover tube and the inner tube are respectively sealed without direct contact, but indirectly contact through a bracket mounted on the inner tube and the cover tube; or another case is that the cover tube and the inner tube are directly or indirectly in contact through a corrugated tube and are sealed, and the inner tube tail end is provided with a sealing plate for plugging; 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 inner tube extending out is exposed outside the cover tube, which is also called a straight-through type vacuum tube; when the vacuum tube collector is installed, the center line of the vacuum tube must coincide or approximately coincide with the focal line of the light collector or the center line of the focal band; 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 center line of the vacuum tube is the position where the three center lines coincide, and the center line is called a three-in-one line;

[0019] The single-pass vacuum tube is provided with a thinner tube with two open ends inserted into the inner tube, which is called an inserted tube type vacuum tube; the inserted tube of the inserted tube type vacuum tube divides the inner tube into two parts in communication with each other, the outer end of the inserted tube is an interface, which is an inlet interface; and there is an outlet interface directly connected with the inner tube; the inlet interface and the outlet interface are located at the tube head of the vacuum tube;

[0020] The tube head and the tube tail of the vacuum tube are respectively connected with two branch pipes connected with the end of the lower beam of the light collector frame; the tube head with two interfaces of the vacuum tube extends into the height static device located on both sides of the trapezoidal seat;

[0021] D, the so-called static changer is a device that changes one end of a pipe with a dynamic interface into the other end with a static interface, the pipe conveying high-temperature fluid has one end as an inlet and the other end as an outlet, but the dynamic-static rule of the static changer is that any static changer connected in the pipeline changes one end of a dynamic outlet interface into the other end of a static outlet interface, or changes one end of a dynamic inlet interface into the other end of a static inlet interface, i.e. without changing the nature of "in" and "out" in the pipeline; the static changer comprises a cavity shell, a tightening hoop, a restraining cylinder, two flexible hoses that can withstand high temperature and are easy to straighten and bend, and a heat insulation material, the cavity shell is a hollow shell, the hollow cavity is composed of at least three plates, two of which are face-to-face plates, which are called end plates of the static changer, and the other is a girdle plate, which is a curved plate formed by wrapping the periphery of the two end plates with a belt-shaped plate and connecting the periphery of the two end plates; the tightening hoop (also called the tightening hoop) is connected to the girdle plate or an end plate; the tightening hoop is a single pipe tightening hoop or a double pipe tightening hoop, the double pipe tightening hoop combines the respective one end of the two hoses inside the cavity shell into a pipe bundle and bundles the two together to fix the end of the two hoses; the single pipe tightening hoop has two, each of which bundles one end of a hose to fix it; the vicinity of the outer port of any tightening hoop is called the static port of the static changer, and the static interface of the hose is near each static port; the other end of each of the two hoses has sufficient bending length in the cavity shell of the static changer and enters the restraining cylinder, and forms a dynamic interface before or after entering the restraining cylinder of the static changer, so each static changer has four interfaces, two of which are dynamic interfaces and the other two are static interfaces, the dynamic interfaces are located at the dynamic port of the static changer, and the restraining cylinder or the vicinity of its two ports are called the dynamic port of the static changer, the static interfaces are located at the static port of the static changer, and the vicinity of the outer port of the tightening hoop is called the static port of the static changer; the interface is a port or a pipe joint that will be connected to other pipes; in any case, two pipes work reciprocatingly in the restraining cylinder, which drives the two hoses in the static changer to reciprocate; the restraining cylinder is a hollow cylinder that is fixedly connected to an end plate of the cavity shell or a girdle plate; the outer surface of the cavity shell is wrapped with a heat insulation material;

[0022] 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 on the two sides of the trapezoidal seat near the two ends of the height shaft; the height variator is referred to as a high variator;

[0023] 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;

[0024] 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;

[0025] Regarding the connecting pipeline, two concepts are first defined: in the series pipeline, the connecting pipeline between the left and right high variators is called a communication pipe, and the connecting pipeline between the high variator and the azimuth variator is called an extension pipe; in the parallel pipeline, the communication pipe and the extension pipe are replaced by a three-way pipe;

[0026] The following conventions are made: when a person faces the height shaft and observes, the left side of the person is referred to as the left end of the height shaft, and the right side of the person is referred to as the right end of the height shaft; the vacuum tube and the high variator outside the left end of the height shaft are referred to as the left vacuum tube and the left high variator, and the vacuum tube and the high variator outside the right end of the height shaft are referred to as the right vacuum tube and the right high variator;

[0027] Briefly speaking, the so-called series connection is that a communication pipe is horizontally placed on the trapezoidal seat, the left static outlet interface of the left high variator and the right static inlet interface of the right high variator are connected through the two ends of the communication pipe, then an extension pipe is used to connect the left static inlet interface of the left high variator and one of the movable interfaces of the azimuth variator, and another extension pipe is used to connect the right static outlet interface of the right high variator and the other movable interface of the azimuth variator; the static outlet and static inlet interfaces of the left high variator are the left outlet and left inlet interfaces of the left vacuum tube head connected through the left high variator; similarly, the static inlet and static outlet interfaces of the right high variator are the right inlet and right outlet interfaces of the right vacuum tube head connected through the right high variator;

[0028] The above said that the communication pipe connects the left static outlet and the right static inlet interface, and vice versa, that is, a communication pipe connects the left static inlet and the right static outlet interface, and then the left static outlet and the right static inlet interface are connected to the two dynamic interfaces of the azimuthal static transformer through two extension pipes; the left static outlet and the left static inlet interface are respectively changed from the outlet and the inlet interface of the left vacuum pipe head connected by the left high transformer dynamic interface; the right static inlet and the right static outlet interface are respectively changed from the inlet and the outlet interface of the right vacuum pipe head connected by the right high transformer dynamic interface; this is the second kind of series pipeline;

[0029] The detailed connection process is that the inlet and outlet interfaces of the left vacuum pipe head are respectively connected to the two dynamic interfaces of the left high transformer, and after passing through the left high transformer, two static interfaces are formed which do not rotate around the height axis, one is called the left static inlet interface, and the other is called the left static outlet interface;

[0030] The inlet and outlet interfaces of the right vacuum pipe head are respectively connected to the two dynamic interfaces of the right high transformer, and after passing through the right high transformer, two static interfaces are formed, one is called the right static inlet interface, and the other is called the right static outlet interface;

[0031] A communication pipe is horizontally arranged on the trapezoidal seat platform, and the left end thereof is connected to the left static inlet interface of the left high transformer or the left static outlet interface, and since it is in series, the right end of the communication pipe is necessarily connected to the right static outlet interface of the right high transformer; the left static outlet interface left on the left high transformer static port is connected to the dynamic interface of the azimuthal static transformer through an extension pipe, and after passing through the azimuthal static transformer, it becomes a full static outlet interface, because it is changed from the left static outlet interface of the left high transformer after extension, and it is called “full static outlet interface” because it does not rotate around the height axis or the azimuthal axis;

[0032] The remaining right static inlet interface on the right high transformer static port is also connected to the remaining dynamic interface of the azimuthal static transformer through an extension pipe, and after passing through the azimuthal static transformer, it becomes a full static inlet interface, because it is changed from the right static inlet interface of the right high transformer after extension; this is the first kind of series pipeline connection mode; the second kind of series mode is described below:

[0033] Vice versa, that is, the left end of a communication pipe is connected to the left static outlet interface, and since it is in series, the right end of the communication pipe is necessarily connected to the right static inlet interface; the left static inlet interface left on the left high transformer static port is connected to one end of an extension pipe, and the other end of the extension pipe is connected to the dynamic interface of the azimuthal static transformer, and after passing through the azimuthal static transformer, it becomes a full static inlet interface; the right static outlet interface left on the right high transformer static port is connected to one end of another extension pipe, and the other end of the extension pipe is connected to the remaining dynamic interface of the azimuthal static transformer, and after passing through the azimuthal static transformer, it becomes a full static outlet interface; this is the second kind of series pipeline connection mode;

[0034] 2. The three variators contained parallel pipeline components, including the left vacuum tube's inlet and outlet interfaces and the right vacuum tube's inlet and outlet interfaces, left and right high variators, and the absolute stationary azimuth variator in the middle of the sun-tracking machine, and two three-way pipes, the high variator is to replace the constraint cylinder in the variator with the vacuum tube's interface inner pipe head, the two soft pipes in the high variator are connected to the inlet and outlet interfaces of the vacuum tube head respectively, the one connected to the inlet interface is called the inlet soft pipe, and the one connected to the outlet interface is called the outlet soft pipe, the two soft pipes are extended out of the tightening hoop and become two static interfaces that do not move with the altitude angle, one is called the left static inlet interface, and the other is called the left static outlet interface, the other three-way pipe is also placed horizontally on the trapezoidal seat 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 dynamic interface of the azimuth variator, and after coming out of the azimuth variator, it becomes the full static inlet interface because it is connected to the two inlets of the left and right vacuum tube heads, the other three-way pipe is also placed horizontally on the trapezoidal seat 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 dynamic interface of the azimuth variator, and after coming out of the azimuth variator, it becomes the full static outlet interface because it is connected to the two outlets of the left and right vacuum tube heads.

[0062] As mentioned above, the pipe connection in Fig. 8 is in parallel, as in Fig. 5. Now, it is described in detail as follows: In Fig. 8, 13 is two three-way pipes, the left port of one three-way pipe is connected with the left static inlet port, and its right port is connected with the right static inlet port; the left port of the other three-way pipe is connected with the left static outlet port, and its right port is connected with the right static outlet port.

Since the left static inlet port and the left static outlet port are connected with the inlet and outlet of the left vacuum tube head on the dynamic port of the left high static converter, respectively, and the right static inlet port and the right static outlet port are connected with the inlet and outlet of the right vacuum tube head on the dynamic port of the right high static converter, respectively.

The rest of the parts with the same numbers as in Fig. 7 have the same meanings.

[0064] Fig. 10 is a front view of the azimuthal variator. Fig. 1 is two hoses on the static port of the variator. Fig. 2 is a bundle of pipes wrapped with thermal insulation material from the port of the variator's tightening hoop 3 (also called the tightening hoop). The two hoses are moving separately in the variator, and their moving state is shown in Fig. 11 as 1'. Since the two hoses do not need thermal insulation material in the cavity shell 5, they move flexibly and the length of the pipes is very short. The thermal insulation material is generally 10 cm thick, and if it is wrapped on a metal corrugated pipe, its diameter will be more than 20 cm, which will be very difficult to bend. Fig. 4 is a fixed connection plate to be connected to the outside world, which is welded to the end of the cavity shell 5. The cavity shell 5 is composed of two facing plates and a belt-shaped plate wrapped around the periphery of the two plates, which are connected to each other to form a cavity shell. As can be seen from Fig. 11, the cavity shell is somewhat similar in shape to a drum. Fig. 6 is thermal insulation material that fully surrounds the cavity shell. Fig. 7 is the body of the variator. Fig. 8 is the bundle of pipes near the constraint cylinder. Fig. 9 is the whole bending hoop, the lower part of which is rooted in the trapezoidal seat platform 12 of the heliostat. It is combined with the constraint cylinder (see Fig. 11) to bend the bundle of pipes by 90° so that it can rotate back and forth in the constraint cylinder. Fig. 10 is an external hard pipe. Fig. 11 is a connecting hoop that can connect the external hard pipe 10 and the hose 1".

[0065] Fig. 11 is a B-B sectional view of Fig. 10. Fig. 1' represents the moving state of the two hoses in the variator. Fig. 15 is a constraint cylinder connected to the cavity shell. Its center line coincides or approximately coincides with the extension of the azimuthal axis, so the hose 1" does not translate in the constraint cylinder, but only rotates back and forth in the constraint cylinder along the azimuthal direction to track the sun. Fig. 8 is thermal insulation material. Fig. 16 is a screw.

[0066] The high variator is similar to this, except that the constraint cylinder 15 in Fig. 11 is replaced by the inner tube head of the vacuum tube, and the right ends of the two hoses 1" are connected to the inlet and outlet interfaces of the vacuum tube head, respectively. Because the center line of the vacuum tube originally coincides with the extension of the height axis, in addition, the high variator does not need the whole bending hoop 9 and the trapezoidal seat platform 12. The rest of the two variators is the same. The high variator is simply called high variator.

[0067] The present invention can also have more embodiments, all of which fall within the scope of the claims of the present invention.

[0068] The advantages of the present invention are:

[0069] 1. The present invention uses a variety of simple and light two-axis heliostat linear focusing heat collection devices to replace the current trough and Fresnel low-efficiency high-cost single-axis heliostat light collection devices, thereby greatly reducing costs.

[0070] 2. Because the two kinds of static converters are invented, the original sun high heat machine's "non-moving interface" with no translation but with a small rotation is cancelled, and the invention improves it to change the two-way large movement interface of the azimuth direction and the elevation angle direction into a completely static external interface, so that the heated working medium can be delivered outward without moving the sealed pipe joint, which is safe and convenient, and completely eliminates the problem of the working medium heat transfer oil sometimes leaking to cause a fire due to dynamic sealing in the existing technology (for example, the current trough type light heat power station sometimes causes a fire accident due to the existence of dynamic sealing).

[0071] The invention of the static converter will completely solve the world's difficult problem that there is no double-axis sun-following direct focusing light heat power station among the world's three or four hundred light heat power stations, although the double-axis sun-following direct focusing machine has the highest light heat and light-to-electricity efficiency, but it cannot store heat in the ground due to its large dynamic sun-following.

[0072] 3. The invention of a simple and lightweight lifting rod type frame replaces the original sun high heat machine's load carrier, which must be welded with a lot of steel rods and plates to increase the bending strength, which is heavy and increases the cost. Because the tensile strength of steel is much greater than the bending strength, the lifting rod type frame is lightweight and greatly reduces the cost.

[0073] 4. The invention overcomes the disadvantage that the cosine loss of the current trough type and Fresnel type heat collecting equipment increases greatly in areas with high latitudes, that is, it is not suitable for use in areas with a geographical latitude of 40° or above. The invention is double-axis sun-following, and the incidence angle of sunlight on the opening light collecting plane of the light collector is always zero, so there is no cosine loss, and the use area is greatly expanded.

[0074] 5. Because the invention of the static converter makes it easy to output the heated working medium outward, it is easy to realize large-scale heat storage in the ground, and the heat preservation time is long, which is very important for solar heat supply or light heat power generation.

[0075] 6. The rod type simple sun high heat machine cancels the original three-way pipe used in the sun high heat machine, which reduces the cost and the flow resistance of the fluid. The three-way pipe must use a very long stainless steel bellows to constantly swing in the elevation angle direction, which increases the fluid resistance and the cost. The second scheme of the invention, i.e. parallel pipe connection, and subsequent schemes, although also use three-way pipes, but the pipe contains a height static converter, so the three-way pipe does not swing, and therefore a hard pipe can be used instead of a bellows, which saves cost and does not wear out the insulation material, and the resistance to fluid is very small.

[0076] 7. The original sun high heat machine's hanging pipe rack, which must be suspended very long, is cancelled, which is easy to deform and requires a lot of steel, and is replaced by installing the heat collecting pipe on the bottom beam of the light collector or the height static converter, which is a dual-purpose device that can save steel and reduce cost, and is safe.

[0077] 8. The original positive branch rod, oblique support rod and other components used in the Sun high heat engine are cancelled, reducing cost and weight, and increasing aesthetics.

The guide rail is fixedly connected to the frame of the frame condenser or is directly or indirectly fixedly connected to the total grid plate of the grid condenser. The lifting rod is transmissionally connected to the variable speed transmission component of the height angle tracking system of the sun tracking machine and is slidingly or rollingly connected to the guide rail. 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; on the tube head, the inner tube extends out of the cover tube, all interfaces are connected with the inner tube, and the cover tube and the inner tube have a sealing and fixed connection on the tube head; on the tube tail, there are two cases: 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; when the vacuum tube collector is installed, the center line of the vacuum tube must coincide or approximately coincide with the focal line or the center line of the focal band of the light collector; 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 center line of the vacuum tube is the position where the three center lines coincide, which is called a three-in-one line; The single-pass vacuum tube is a thinner tube with two open ends inserted into the inner tube, called an inserted tube vacuum tube, the inserted tube of the inserted tube vacuum tube divides the inner tube into two parts that are connected with 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 with the inner tube; the inlet interface and the outlet interface are located at the tube head of the vacuum tube; The tube head and the tube tail of the vacuum tube are connected with two branch pipes connected with the end of the lower beam of the light collector frame, respectively, and the tube head with two interfaces extends into the height variable stabilizer inside the trapezoidal seat; D, The so-called static changer is a device that changes one end of a pipe with a dynamic interface into the other end with a static interface. The pipe that transports high-temperature fluid has one end as an inlet and the other end as an outlet. However, the dynamic-static rule of the static changer is that any static changer 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 changer 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 changer. 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 periphery of the two end plates. The tightening hoop, also called the 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, 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 changer. Near each static port, there is a static interface of the hose. The other end of each of the two hoses has sufficient bending length inside the cavity shell of the static changer and enters the restraining cylinder. Before or after entering the restraining cylinder of the static changer, each forms a dynamic interface. Therefore, each static changer 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 changer, which are inside the restraining cylinder or near its two ports. The static interfaces are located at the static ports of the static changer, 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 changer 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 a 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 respectively located near the two sides of the trapezoidal seat at the two ends of the height shaft; the height variator is referred to as a high variator; E, the medium pipeline component is a pipeline component containing three variators, the pipeline component containing three variators includes an azimuth variator, two high 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 high variators is called a communication pipe, and the connecting pipeline between the high variator and the azimuth variator is called an extension pipe; in the parallel pipeline, the communication 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 referred to as the left end of the height shaft, and the right side of the person is referred to as the right end of the height shaft; the vacuum tube and the high variator outside the left end of the height shaft are referred to as the left vacuum tube and the left high variator, and the vacuum tube and the high variator outside the right end of the height shaft are referred to as the right vacuum tube and the right high variator; In simple terms, series connection means placing a communication pipe horizontally on the trapezoidal seat, with its two ends connecting the left static outlet interface of the left high variator and the right static inlet interface of the right high variator, then connecting the left static inlet interface of the left high 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 high variator and the other movable interface of the azimuth variator with another extension pipe; the static outlet and inlet interfaces of the left high variator are the left outlet and inlet interfaces of the left vacuum tube head connected by the movable interfaces of the left high variator, which are changed by the left high variator; Similarly, the static inlet and outlet interfaces of the right high variator are the right inlet and outlet interfaces of the right vacuum tube head connected by the movable interfaces of the right high variator, which are changed by the right high variator; The above describes the communication pipe connecting the left static outlet and right static inlet interfaces, and the reverse is also true, that is, a communication 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 by the movable interfaces of the left high variator, which are changed by the left high variator; the right static inlet and right static outlet interfaces are the inlet and outlet interfaces of the right vacuum tube head connected by the movable interfaces of the right high variator, which are changed by the right high variator; this is the second series pipeline; Detailed connection process is: the left vacuum pipe head import and export two interfaces respectively and the left high variable two dynamic interface access, through the left high variable, constitute not around the height axis rotation two static interface, one called left static import interface, the other called left static export interface; The right vacuum pipe head import interface and export interface respectively and the right high variable two dynamic interface access, through the right high variable, constitute two static interface, one called right static import interface, the other called right static export interface; In the trapezoidal seat platform, a connecting pipe is transversely arranged, the left port of the connecting pipe is connected with the left static import interface of the left high variable or the left static export interface, since it is in series, the right port of the connecting pipe is necessarily connected with the right static export interface of the right high variable; the left static export interface of the left high variable 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, since it is the left static export interface of the left high variable after extension, 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, since 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 described below: On the contrary, it is also the same, that is, the left end of a connecting pipe is connected with the left static export interface, since it is in series, the right end of the connecting pipe is necessarily connected with the right static import interface; the left static import interface outside the left end of 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 outside the right end of the height axis is connected with one end of another extension pipe, 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.

2. The simple and efficient solar high heat engine according to claim 1, characterized in that: The three-variable-attenuator containing parallel pipeline components include the left vacuum tube's inlet and outlet interfaces and the right vacuum tube's inlet and outlet interfaces, left and right high variable attenuators, and the absolute stationary azimuth variable attenuator in the middle of the sun-tracking machine, and two three-way pipes. The high variable attenuator is a vacuum tube with interfaces replacing the constraint cylinder in the variable attenuator. The two soft tubes in the high variable attenuator have their movable interfaces connected to the inlet and outlet interfaces of the vacuum tube head, respectively. The soft tube connected to the inlet interface is called the inlet soft tube, and the soft tube connected to the outlet interface is called the outlet soft tube. The two soft tubes extend out of the tightening hoop and become two static interfaces that do not move with the altitude angle. One is called the left static inlet interface, and the other is called the left static outlet interface. The other high variable attenuator has one called the right static inlet interface and the other called the right static outlet interface. One three-way pipe is placed horizontally on the trapezoidal seat 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 movable interface of the azimuth variable attenuator. After exiting the azimuth variable attenuator, it becomes the full static inlet interface because it is connected to the two inlets of the left and right vacuum tube heads. The other three-way pipe is also placed horizontally on the trapezoidal seat 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 movable interface of the azimuth variable attenuator. After exiting the azimuth variable attenuator, it becomes the full static outlet interface because it is connected to the two outlets of the left and right vacuum tube heads.
