Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic power generation, and more particularly to a high-concentration photovoltaic power generation system and application thereof. BACKGROUND

[0002] Photovoltaic power generation is a clean energy utilization method using sunlight to generate electricity. In the prior art, photovoltaic power generation technology has been applied in many ways. The following are some examples of photovoltaic power generation.

[0003] First, natural sunlight is compressed and projected onto a small area of photovoltaic cell chips through a series of optical lenses, and the sunlight is tracked by a double-axis sun tracker to track the sun rotation, thereby realizing high-concentration and photovoltaic power generation. The advantage of this technology is that the use area of photovoltaic cell chips is greatly reduced, and the power generation efficiency per unit area of photovoltaic cell chips is greatly improved. The area of the photovoltaic power generation assembly is reduced in proportion, but it can only be installed behind each condensing lens. The photovoltaic power generation assembly and the condensing lens are inseparable and are installed together in places where sunlight can be received, such as open fields, building roofs, etc. Since the photovoltaic cell chips are fixedly installed behind each condensing lens at the focal point and cannot be separated, they cannot be concentrated together, and the area and volume have not been reduced, and the weight has not been reduced. Moreover, the photovoltaic power generation panel is fixed behind the optical lens and cannot be moved flexibly.

[0004] Second, solar electric vehicle technology, solar photovoltaic panels cover the body of an electric vehicle, and convert solar energy into electrical energy under normal solar radiation and store it in a power storage battery, thereby providing electrical energy for the electric vehicle. Given that the average conventional solar radiation on the earth's surface is about 1200 watts per square meter, the power generation of the solar photovoltaic panel under this conventional sunlight radiation is too low, and in order to meet the demand for electrical power of the electric vehicle, the area of the solar photovoltaic panel must be increased. This results in two consequences: on the one hand, even if the entire vehicle body is covered with photovoltaic panels, it is not enough to provide the required electrical power for the vehicle; on the other hand, covering the entire vehicle body with photovoltaic panels will result in a significant increase in the weight or volume of the vehicle, which in turn will significantly increase the electrical power consumption of the vehicle, resulting in most of the electrical power generated by the solar photovoltaic panel being used to offset the increased weight, and even possibly not being worth the cost, i.e. the electrical power generated by the increased area and weight of the solar photovoltaic panel is not enough to offset the increased weight of the vehicle. In addition, the solar photovoltaic panel exposed on the surface of the vehicle body is not safe and is easily damaged by scratches and collisions, and the solar electric vehicle can only generate electricity and charge in places with plenty of sunlight, and the power generation efficiency per unit area of the photovoltaic cell is not high.

[0005] The third wireless transmission charging technology, the electric energy is first converted into radio frequency or microwave signal by the transmitting coil unit, then transmitted wirelessly in the air to the receiving coil unit and received by the receiving coil unit, and then converted into electric energy, and finally the battery is charged to realize the wireless transmission and wireless charging function of the electric vehicle, but the disadvantage of this technology is that it cannot implement long-distance transmission and charging for the electric device, and it is impossible to implement long-distance charging for the moving electric device, because the wireless transmission electric energy loss is too large, and the transmitting and receiving efficiency is not high.

[0006] In summary, the existing problems of the prior art are that the existing photovoltaic power generation panel can only be installed in a place illuminated by the sun, and the unit area power generation efficiency is too low under the conventional sunlight radiation power, the high-multiple light power generation technology can reduce the photovoltaic cell chip area in proportion, but cannot move freely without the light condensing lens, and can only move with the sunlight collector and be fixedly installed in a place facing the sunlight, and the wireless transmission charging technology can only realize short-distance wireless charging because of the too large high-frequency electromagnetic energy loss in the transmitting, transmitting and receiving processes, and cannot realize long-distance electric energy transmission and charging.

DETAILED DESCRIPTION

[0067] In order to make the person in the art better understand the technical scheme of the present application, the technical scheme of the present application will be described clearly and completely below in combination with the drawings of the present application. Based on the embodiments in the present application, other similar embodiments obtained by the person in the art without making creative efforts shall belong to the protection scope of the present application. In addition, the direction words mentioned in the following embodiments, such as "up", "down", "left", "right", etc. are only the directions of the drawings, therefore, the direction words used are used for illustration but not for limiting the present application.

[0068] The present application will be further described below in combination with the drawings and the preferred embodiments.

[0069] Embodiment one: a high light gathering photovoltaic power generation system, referring to the drawings Figure 1 - the drawings Figure 7 , comprising a high light gathering device 1 and a power generation device 2; the high light gathering device 1 comprises a collecting device 11, a transmission device 12 and a projection device 13, the collecting device 11 is used for high multiple gathering compression and collection of natural sunlight; the transmission device 12 is connected with the high light gathering collecting device 11 and is used for transmission of the high light gathering after the natural sunlight is high multiple gathered and compressed; the projection device 13 is connected with the transmission device 12 and is used for projection of the high light gathering transmitted by the transmission device 12; the power generation device 2 is used for receiving the high light gathering projected by the projection device 13 and converting the high light gathering into electric energy.

[0070] The high light gathering device 1 is responsible for high multiple gathering compression and collection, transmission and projection of the natural sunlight. Generally, the high light gathering device 1 is installed in a specific place, similar to a car refueling station; and the power generation device 2 is responsible for converting the high multiple gathering compressed sunlight, that is, the high light gathering, projected by the high light gathering device 1 into electric energy. Generally, it is set as a movable equipment, because there is no fixed electrical connection between the power generation device 2 and the high light gathering device 1, so that it can be installed on a mobile device such as an electric vehicle, a drone, a robot, a mobile terminal, etc.

[0071] The natural sunlight is compressed by the high light gathering device 1 and then projected onto the power generation device 2, and then converted into electric energy by photoelectric conversion and stored in the battery 4 of the electric vehicle and other mobile devices. It should be noted that there is no electrical contact or connection between the high light gathering device 1 and the power generation device 2. The high light gathering device 1 directly projects high light on the power generation device 2.

[0072] It should be noted that the high light gathering device 1 and the power generation device 2 can be kept at a very close distance or a very far distance. There is only a light connection between the high light gathering device 1 and the power generation device 2, and there is no electrical connection or even no physical mechanical connection. When the high light gathering device 1 projects high light for high light photovoltaic power generation, the power generation device 2 can be static or dynamic. The light connection between the high light gathering device 1 and the power generation device 2 can be manually aligned or completed by using advanced artificial intelligence algorithms and target object visual recognition intelligent control means. For the latter, the high light gathering device 1 has the ability to automatically identify, align and track the power generation device 2 and automatically adjust the high light field distribution, so that the high light projected by the high light gathering device 1 matches the parameters of the power generation device 2, and then the high light is converted into the electric energy required by the electric vehicle and other mobile devices to the greatest extent, so as to improve the utilization rate of high light and the endurance mileage of electric vehicles and other mobile devices.

[0073] Specifically, the power generation device 2 is set as a movable power generation device 2 or a fixed power generation device 2. That is, the power generation device 2 can be set on a movable device or a fixed device.

[0074] Specifically, the high light gathering device 1 projects high light to one or more power generation devices 2.

[0075] The installation position of the high light gathering device 1 is relatively fixed, and the power generation device 2 can be completely free to move. The relationship between the two can not be a one-to-one correspondence, that is, one high light gathering device 1 can correspond to one or more power generation devices 2. Although when one high light gathering device 1 corresponds to multiple power generation devices 2, it cannot provide high light to multiple power generation devices 2 at the same time, it greatly improves the use frequency of the high light gathering device 1, thereby improving the use value of the high light gathering device 1. Since the light gathering multiple of the high light can be very high, at least one hundred times, even thousands and tens of thousands of times or more, accordingly, the required power generation device 2 area will be greatly reduced, and the weight will be greatly reduced, so the photovoltaic power generation device 2 can become very small and light, and then can be installed on the electric vehicle, unmanned aerial vehicle, robot, mobile intelligent terminal and other mobile devices without additional weight and volume.

[0076] The high light gathering device 1 corresponds to a fixed charging pile, and the power generation device 2 is installed on a mobile device, so that the mobile device can be charged at the high light gathering device 1 when the mobile device needs to be charged, and the mobile device can leave after the charging is completed, so that the high frequency use can be realized.

[0077] Specifically, the collection device 11 is responsible for high multiple sunlight compression and collection, and the collection device 11 includes a light collecting plate 111, an optical lens 112, and a fiber connector 113; the optical lens 112 is arranged on the light collecting plate 111, and at least one optical lens 112 is arranged on the light collecting plate 111, and the optical lens 112 is used for focusing and compressing natural sunlight; each optical lens 112 corresponds to one optical lens 112, and the optical lens 112 focuses the compressed sunlight on the corresponding fiber connector 113, and the fiber connector 113 is connected with the transmission device 12.

[0078] The optical lens 112 is used for collecting and compressing natural sunlight, and the compression multiple is at least 100 times or more, 1000 times or more, even 10,000 times or more, or even 100,000 times or more. The compressed sunlight is focused on the transmission device 12 fixed on the fiber connector 113, so as to be coupled into the transmission device 12. The optical lens 112 can be spherical, quasi-spherical, or non-spherical, such as a Fresnel lens.

[0079] Specifically, the collection device 11 further includes a double-axis power mechanism 114 and a sun sensor 115, the double-axis power mechanism 114 is used to drive the light collecting plate 111 to track the sun position, and the sun sensor 115 is arranged on the light collecting plate 111 to obtain the sun position.

[0080] The double-axis rotating mechanism is a mechanical power mechanism, which provides power for the light collecting plate 111 to track the sun trajectory on the horizontal axis and the pitch axis. Under the guidance of the sun sensor 115 signal, the double-axis power mechanism 114 carrying the light collecting plate 111 precisely tracks the sun position, so as to maximize the collection, compression and collection of sunlight.

[0081] Specifically, the ratio of the light collecting area of the optical lens 112 to the formed focal spot area is the sunlight compression and collection multiple of the collection device 11. For example, the diameters of the optical lens 112 and the formed focal spot are 100 mm and 1 mm respectively, and the sunlight compression and collection multiple of the optical lens 112 is 10,000 times.

[0082] Specifically, the transmission device 12 is arranged as an optical fiber transmission network, one end of the optical fiber transmission network is connected with the optical fiber receiver, and the other end is connected with the projection device 13. The optical fiber is usually an optical fiber bundle bundled by a plurality of optical fibers, and there is also a case of one optical fiber. In the embodiment, the optical fiber bundle bundled by a plurality of optical fibers is adopted. The diameter and numerical aperture of the optical fiber are very important for the sunlight collection efficiency. The larger the diameter and the numerical aperture of the optical fiber are, the easier it is to collect solar energy, and the higher the optical coupling efficiency is. However, the larger the diameter and the numerical aperture of the optical fiber are, the higher the cost of the optical fiber is, and the more difficult it is to bend, thereby increasing the difficulty of engineering construction.

[0083] In order to reduce the transmission loss of the optical fiber, the material of the optical fiber is mainly low-loss quartz glass, and can also be arranged as other solid glass materials or even plastic materials.

[0084] The length of the optical fiber can be set according to requirements, such as 10 meters, 100 meters, or even more than 500 meters, so as to transmit the high light from the collection device 11 to the projection device 13, and support the projection device 13 to move freely within the length of the optical fiber.

[0085] The end of the optical fiber transmission network connected with the projection device 13 is arranged as an optical fiber or an optical fiber bundle composed of a plurality of optical fibers. The front end of the optical fiber transmission network is connected with the optical fiber connector 113 and located on the optical axis focal point position of the optical lens 112. Each optical fiber corresponds to an optical lens 112 and is responsible for receiving the sunlight gathered and compressed by the optical lens 112. At least one optical fiber is arranged at the end of the optical fiber transmission network, that is, the emission end, and can also be an optical fiber bundle composed of a plurality of optical fibers, which is inserted into the projection device 13 and connected with the projection device 13, and is responsible for transmitting the high light provided by the optical fiber transmission network to the high light projection device 13. When the end of the optical fiber transmission network connected with the projection device 13 is arranged as an optical fiber bundle composed of a plurality of optical fibers, the optical fiber transmission network is arranged as an optical fiber bundle composed of a plurality of optical fibers, which realizes an end-to-end optical fiber transmission mode. Of course, an end-to-end optical fiber bundle connection mode can also be arranged, which makes the optical fiber transmission network further compress the sunlight during the transmission of the sunlight. For example, two optical fibers are bundled into one optical fiber, or three optical fibers are bundled into one optical fiber, which can further compress the sunlight and save the cost of optical fiber investment.

[0086] The projection device 13 comprises a mechanical support mechanism 131 and a high light projection device 132 arranged on the mechanical support mechanism 131; the high light projection device 132 comprises a fiber adapter 1321 connected with a fiber transmission network and a zoom lens 1322, the zoom lens 1322 adjusts the size of the light field distribution of the high light by adjusting the distance from the fiber adapter 1321; the mechanical support mechanism 131 is arranged as a mechanical power mechanism with at least two-axis rotation freedom of pitch and level.

[0087] The zoom lens 1322 can be a single zoom lens 1322 or a combination of multiple lenses, and its function is to shape the light field of the high light projected by the projector to obtain the required light field distribution of the power generation device 2. When the zoom lens 1322 is arranged as a single zoom lens 1322, the zoom lens 1322 is optically coaxial with the fiber adapter 1321 and located behind the fiber adapter 1321; when the zoom lens 1322 moves to the left, the area of the light spot output by the high light projection device 132 becomes larger; when the zoom lens 1322 moves to the right, the area of the light spot output by the high light projection device 132 becomes smaller; by adjusting the distance between the zoom lens 1322 and the optical adapter, that is, the focal length, the light field distribution of the high light can be adjusted, that is, the size of the light spot can be adjusted, so that the sunlight can be further compressed and collected, that is, the compression multiple of the high light can be changed.

[0088] Specifically, the ratio of the sum of the light collection areas of all optical lenses 112 of the collection device 11 to the area of the light spot formed by the high light projection device 132 is the sunlight compression and collection multiple of the high light device 1. For example, if the sum of the light collection areas of all optical lenses 112 of the collection device 11 and the area of the light spot formed by the high light projection device 132 are 2m 2 and 100mm 2 respectively, then the sunlight compression and collection multiple of the high light device 1 is 20000 times.

[0089] The fiber adapter 1321 is connected with the fiber end of the fiber transmission network, that is, the emission end of the fiber, and provides optical positioning and mechanical connection for the emission end of the fiber. The end of the fiber transmission network connected with the fiber adapter 1321 comprises a plurality of fibers, which can be arranged in a circular pattern on the end face of the fiber adapter 1321, or in a square pattern, or in other pattern arrangement, which depends on the requirements of the power generation device 2. The pattern of the fiber end on the end face of the fiber adapter 1321 corresponds to the shape of the light field distribution of the projector.

[0090] Specifically, the mechanical support mechanism 131 is arranged to include a mechanical power mechanism with at least two-axis rotation freedom of pitch and horizontal, so as to provide the high light projector 132 with the freedom of two-axis rotation of pitch and horizontal. More specifically, the mechanical support mechanism 131 can be manually adjusted by hand, or it can be a two-axis rotation mechanism introduced with computer artificial intelligence algorithm and intelligent control, which automatically adjusts the horizontal angle and pitch angle of the mechanical support mechanism 131 according to the position of the power generation device 2, so that the high light projector 132 can accurately project high light on the power generation device 2.

[0091] In addition to adjusting the high light projection direction, the high light projection device 13 can also precisely adjust the light field distribution of the high light, so as to better match the shape and area parameters of the photovoltaic power generation device 2.

[0092] The high light projection device 13 adjusts the sunlight projection direction, that is, the horizontal angle and pitch angle, according to the position of the power generation device 2, and adjusts the light field distribution of the high light, that is, the shape and size of the light spot, according to the shape and area to be matched by the power generation device 2. The shape and area to be matched by the power generation device 2 are the shape and area of the photovoltaic cell chip 21. By adjusting the shape and size of the light spot to be the same as the shape and size of the photovoltaic cell chip 21, the power generation efficiency and power generation capacity of the power generation device 2 can be maximized.

[0093] Specifically, the power generation device 2 further includes a heat sink 22.

[0094] Specifically, the photovoltaic cell chip 21 selects a high-performance photovoltaic cell, generally selects a high-efficiency semiconductor photovoltaic cell chip 21 with high photoelectric conversion efficiency and wide working range, including a multi-junction photovoltaic cell chip 21 made of gallium arsenide (GaAs), gallium nitride (GaN), indium phosphide (InP), zinc telluride (ZnTe), or cadmium sulfide (CdS) three-five or two-six compound semiconductor materials, and a perovskite solar photovoltaic cell chip 21, etc. It has high photosensitivity, high conversion efficiency, wide light intensity working range, and good temperature characteristics, and can still work stably even under thousands or even tens of thousands of times of sunlight. The higher the photoelectric conversion efficiency, the more high-multiple sunlight is converted into electrical energy, and the less sunlight is converted into heat energy; the wider the working range, the more light energy is converted into electrical energy, and the smaller the required photovoltaic chip area.

[0095] The photovoltaic cell chip 21 can be square, circular, or any other shape, but must be consistent with the light field distribution of the high light projected by the high light projection device 13, that is, the shape of the light spot, in order to achieve the best photovoltaic power generation effect.

[0096] Because the light-gathering multiple is high, the photovoltaic current density per unit area is high, thus causing the photovoltaic cell chip 21 to generate a large amount of redundant heat, and the photovoltaic cell chip 21 must be welded to the heat sink 22 to dissipate the large amount of redundant heat, so as to ensure the normal operation of the photovoltaic cell chip 21 and prevent it from being burned.

[0097] The heat sink 22 can be a multi-tooth metal fin mechanism, an integrated heat pipe or a liquid cooling system, a phase change heat sink mechanism, or other forms of heat sink mechanisms.

[0098] Embodiment two: a high light-gathering photovoltaic power generation system application, as shown in the accompanying Figure 8 The high light-gathering photovoltaic power generation system described in embodiment one is applied to a mobile device such as an electric vehicle, a drone, a robot, a mobile intelligent terminal, and is connected with a charging device and an electric motor 5 thereof. The charging device usually includes a charging management circuit (MPPT) 3 and a storage battery 4. The power generation device 2 generates a photovoltaic current under high light-gathering irradiation, which is stored in the storage battery 4 after passing through the management circuit 3. The storage battery 4 is connected with the electric motor 5, thereby providing the required electric energy for the movement or other power output of the electric motor 5.

[0099] The storage battery 4 can be a power storage battery 4, a storage battery 4, a fuel storage battery 4, a chemical storage battery 4, a super capacitor storage battery 4, a fuel storage battery 4, or a solid-state storage battery 4.

[0100] In view of the high light-gathering projection onto the photovoltaic cell chip 21, the photoelectric conversion efficiency and photovoltaic current density of the power generation device 2 far exceed those of a conventional photovoltaic power generation device 2, and can quickly provide sufficient electric energy supply for a mobile device such as an electric vehicle, a robot, a drone, or a mobile intelligent terminal in a very short time. The power generation device 2 is further connected with a DC-DC converter, an MPPT (maximum power point tracking) controller, and a high-performance storage battery 4 or a super capacitor, to efficiently convert, regulate, and store the electric energy generated by the photovoltaic cell, so as to meet the light supplement power generation and charging needs of the mobile device such as the electric vehicle, the drone, the robot, or the mobile intelligent terminal.

[0101] The high light gathering device 1 has a light gathering multiple of at least 100 times, or even thousands of times. If the sunlight with a light gathering multiple of tens of thousands of times is projected onto the photovoltaic cell chip 21 and the photovoltaic cell chip 21 can still work stably under tens of thousands of times of sunlight, then under the same power demand, the area of the photovoltaic cell will also decrease by tens of thousands of times. That is, under the condition of generating the same power, the required area and weight of the photovoltaic cell chip 21 will also decrease by tens of thousands of times, so that the volume and weight of the photovoltaic cell chip 21 will become very small and light, so that the increased load weight and volume of the mobile device after installing the photovoltaic power generation device 2 can be almost negligible, which makes it possible to directly install the photovoltaic power generation device 2 on the mobile device such as an electric vehicle, a robot, a unmanned aerial vehicle, and a mobile intelligent terminal, and the installation position can be flexibly adjusted according to the shape of the electric vehicle and other mobile devices, so as to meet the needs of different application scenarios and users.

[0102] The collection device 11 is fixedly installed in a place full of sunlight to gather and compress natural sunlight with high multiple, the receiving end of the transmission device 12 is connected with the collector to collect and transmit the sunlight gathered with high multiple, and then the sunlight is transmitted to the projection device 13. The projection device 13 can move within the length range of the optical fiber of the transmission device 12 to select the most suitable position for high light projection. When light supplementing power generation and charging are needed, the mobile device enters the projection active range of the projection device 13, and the projection device 13 can adjust the high light projection direction and light field distribution according to the position of the power generation device 2 on the mobile device and the shape parameters of the power generation device 2, so as to accurately project the high light onto the photovoltaic power generation device 2 for light supplementing power generation and charging.

[0103] Furthermore, the power generation device 2 can be installed on a mobile device in motion, such as an electric vehicle, a robot, or a unmanned aerial vehicle in motion, and the projection device 13 can be provided as a horizontal and pitching double-axis rotating mechanical support mechanism 131 under the control of artificial intelligence precision and a zoom lens 1322 under the control of artificial intelligence which can change the light field distribution, so that the projection device 13 can accurately project the high light with specific horizontal angle, pitching angle, and specific light field distribution shape onto the photovoltaic cell chip 21 according to the position of the power generation device 2 and the shape and size of the photovoltaic cell chip 21, thereby maximizing the photoelectric conversion efficiency and the photovoltaic power generation amount.

[0104] More specifically, the projection device 13 can be provided as an intelligent controllable device, which can continuously track the position of the power generation device 2 in motion, so as to continuously and accurately project the high light onto the photovoltaic cell chip 21.

[0105] ​More specifically, the natural sunlight in the present application can be directly from the sun, or indirectly from the sun, such as from the moon, or from artificial electric light source, including semiconductor laser, semiconductor LED light source, fiber laser, high-pressure sodium lamp, metal halide lamp, electrodeless lamp, xenon lamp, etc.

[0106] The high-concentration photovoltaic power generation system in Example One is applied to the electric vehicle as follows:

[0107] Referring to the attached Figure 9 The power generation device 2 is installed on the side of the electric vehicle body and connected with the management circuit 3 and power storage battery 4 installed on the bottom of the vehicle body to provide power for the electric motor 5, thus forming a high-concentration solar electric vehicle.

[0108] The collection device 11 is set in a place exposed to the sun, and the optical fiber transmission network is connected with the collection device 11, and the optical fiber transmission network is laid to extend to a place near the example highway, which can be called a "light supplement station", that is, a place where the electric vehicle supplements "high-concentration" energy. The projection device 13 is installed in the light supplement station, and the projection device 13 is connected with the collection device 11 exposed to the sun through the optical fiber transmission network.

[0109] The projection device 13 is set as a gun-shaped high-concentration projection device 13, which includes an optical fiber adapter 1321 and a zoom lens 1322, and is connected with the emitting end of the optical fiber to receive high-concentration light from the collector and the optical fiber transmission network. It should be noted that if the projection device 13 implements ultra-close projection of high-concentration light to the power generation device 2, the zoom lens 1322 can be omitted.

[0110] The high-concentration photovoltaic power generation system in Example One is applied to the electric vehicle and static high-concentration projection photovoltaic power generation and charging.

[0111] Referring to the attached Figure 10 The power generation device 2 is set on the top of the electric vehicle body, and the projection device 13 is set far away. When high-concentration power generation is needed, the power generation device 2 is erected on the top of the electric vehicle body to facilitate the identification and capture of the power generation device 2 by the high-concentration projection device 13, and then the projection device 13 projects high-concentration light to the photovoltaic cell chip 21 remotely and accurately.

[0112] During the process of power generation and charging, the electric vehicle can be static or dynamic.

[0113] When the power generation device 2 is applied to a robot, the power generation device 2 can be arranged on the chest or back of the robot. When the robot needs to generate power by high light concentration, the robot only needs to be moved to a certain distance from the projection device 13, and high light concentration can be achieved by the projection device 13 to project high light concentration on the power generation device 2 on the chest or back of the robot to realize high light concentration power generation and charging.

[0114] When the power generation device 2 is applied to a mobile intelligent terminal, the power generation device 2 can be installed on the back of the mobile intelligent terminal. A card frame structure for placing the mobile intelligent terminal is arranged. When charging, the back of the mobile intelligent terminal is placed in the card frame structure, so that the projection device 13 can accurately project high light concentration on the photovoltaic cell chip 21 on the mobile intelligent terminal.

Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as the protection scope of the present application.
