Description

Technical Field

[0001] This invention relates to the field of photovoltaic generator technology, and in particular to a light pollution control device for photovoltaic generator sets. Background Technology

[0002] Solar energy is a renewable energy source, generated by the nuclear energy released through the fusion of hydrogen and helium atoms inside the sun. It is the radiant energy emanating from the sun. The vast majority of the energy needed by humankind comes directly or indirectly from the sun. Plants release oxygen and absorb carbon dioxide through photosynthesis, converting solar energy into chemical energy stored within their bodies. Fossil fuels such as coal, oil, and natural gas are also primary energy sources formed from ancient plants and animals buried underground over long geological periods. With fossil fuels becoming increasingly scarce, solar energy has become an important component of human energy use and continues to develop. Solar energy is utilized through two methods: photothermal conversion and photovoltaic conversion. Solar power generation is an emerging renewable energy source.

[0003] A search of Chinese patent CN113364397A reveals a CNC fan that is easy to install. This patent discloses that, in reservoirs or other liquid environments, taking river water as an example, the base and frame are integrated and fixed to both banks of the river. The two sides of the cable 3 are connected to the two frames respectively, so that the cable can cross the river surface and allow the photovoltaic panels to be installed above the river surface. The length of the cable is greater than the width of the river surface it covers. Several hanging groups are arranged along the length of the river. The photovoltaic panels create a relatively dark environment, reducing the solar radiation received by the liquid and lowering the liquid temperature. As the liquid temperature decreases, the oxygen content of the liquid relatively increases. Fish have a relatively slower metabolism in low-temperature environments, which helps to create a suitable environment for fish growth in tropical and subtropical regions.

[0004] However, the above-mentioned solutions have the following problems during use: After photovoltaic panels cover the water bodies of rivers, lakes and reservoirs, they will directly block sunlight, lower the water temperature, affect the normal photosynthesis of phytoplankton in the river, lake and reservoir areas, and thus reduce the dissolved oxygen concentration in the water. As the area of ​​the solar panels on the water surface increases, the water temperature shows a linear downward trend, which affects the ecological environment in the river and affects the normal natural development of the river or the external water area.

[0005] Therefore, this application provides a light pollution control device for photovoltaic generator sets to meet the requirements. Summary of the Invention

[0006] The purpose of this application is to provide a light pollution control device for photovoltaic generator sets to solve the problems mentioned in the background.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A light pollution control device for a photovoltaic generator set includes a mounting base, an adjustment cavity, and a light-receiving part.

[0010] The photovoltaic panel is fixedly installed on one side of the sliding column surface. A second reflector is installed inside the adjustment cavity. A reflective layer is provided on one side of the second reflector. One side of the photovoltaic panel abuts against the reflective layer on one side of the second reflector. A lifting member is slidably installed inside the second reflector. One side of the sliding column is fixedly installed through a sliding connecting rod and one side of the lifting member. A compression member is evenly arranged on one side of the lifting member. A sliding connecting rod is connected to one side of the lifting member. A sliding groove is opened on the side wall of the adjustment cavity. The sliding connecting rod slides through the second reflector and the side wall of the adjustment cavity inside the sliding groove and abuts against one side of the first adjustment part. One side of the compression member abuts against one side of the interior of the second reflector, and the other side abuts against the other side of the lifting member. A first reflector is installed on one side of the sliding column.

[0011] Preferably, the adjustment cavity is a hollow cone-shaped structure, the number of light-transmitting elements is four, and they are inclined and opposite to one side of the surface of the first adjustment part. The number of the first adjustment part and thus the number of light-transmitting elements are adapted to each other, and the number of the second adjustment part changes with the number of the first adjustment part.

[0012] Preferably, the sum of the tilt angle of the light-transmitting element and the radius between the second adjustment part and the first reflective element, the light-transmitting element is made of a light-transmitting material, the curvature values ​​between the first adjustment part and the second adjustment part are equal, each of the first adjustment part and the second adjustment part forms a group, the second adjustment part moves relative to the first adjustment part, and adjusts the distance between the second adjustment part and the first adjustment part.

[0013] Preferably, the distance between the light-transmitting element and the second adjusting part is a fixed value, the value of the first reflector and one side of the first adjusting part is a fixed value, the first adjusting part is a concave lens, the second adjusting part is a convex lens, the sliding column is in motion relative to the interior of the adjusting cavity, the first reflector is a plane mirror, and the photovoltaic panel changes with the movement of the sliding column.

[0014] Preferably, the lifting member has a ring-shaped structure, the compression member is a spring-shaped structure made of an expansion alloy material, the compression members are evenly distributed along the center point of one side of the lifting member and are adapted to the shape of one side of the lifting member, a sliding cavity is installed between one side of the second reflector and the photovoltaic panel, and one side of the sliding column is slidably installed inside the sliding cavity.

[0015] Preferably, a locking member is installed on one side of the photovoltaic panel, and a first connecting member is installed on one side of the locking member. The first connecting member is installed on one side of the photovoltaic panel through the locking member, and the number of photovoltaic panels installed varies with the number of the second adjustment parts.

[0016] Preferably, a second connector is installed inside the first connector, the diameter of the second connector is larger than the inner diameter of the first connector, a locking frame is uniformly installed on one side of the sliding cavity, the locking frame is a groove-shaped structure, one side of the second connector is connected to the inner side of the locking frame, and the number of locking frames installed varies with the number of photovoltaic panels installed.

[0017] Preferably, the surface of the sliding column has at least two sets of tension members in a symmetrical shape. The number of tension members varies with the number of locking frames installed. The number of tension members installed is two per set, and the other side of the tension member is installed on one side of the locking member.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In the above scheme, the lifting component moves to one side of the sliding column via the compression component and abuts against the sliding column. This causes the sliding column to slide, thereby changing the position of the photovoltaic panel. One side of the photovoltaic panel moves away from the side of the reflective layer on the surface of the second reflector. This increases the spatial distance between the second reflector and the photovoltaic panel, while simultaneously changing the position of the first reflector on the other side of the sliding column. This ensures that the sunlight beams generated by the outside are always refracted and reflected inside the regulating cavity. This reduces the need for large-area photovoltaic panel installations in existing technologies to block sunlight from reaching the water surface, lowering water temperature and affecting the photosynthesis of phytoplankton. Consequently, it increases the concentration of dissolved oxygen in the water. This scheme eliminates the need for a large base frame to impact the aquatic environment, increases the diversity of the aquatic ecosystem, and ensures the normal natural development of the aquatic ecosystem.

[0020] 2. In the above scheme, sunlight first enters the regulating cavity through the light-receiving part, and then shines on the surface of the light-transmitting element located inside the regulating cavity. The beam of sunlight passes through the light-transmitting element and shines on one side of the first regulating part opposite to the light-transmitting element. While ensuring that the beam of sunlight penetrates to one side of the light-transmitting element, the beam on the other side will not be refracted, causing beam redundancy and glare on the outside of the light-transmitting element. The beam of sunlight passing through the light-receiving part shines on one side of the first reflector located inside the regulating cavity, producing a specular refraction phenomenon. This refracts the beam of sunlight onto one side of the first regulating part, suppressing the light scattering of the beam from the first regulating part itself through the light-transmitting element, thus ensuring the penetration of the external beam of sunlight into the first regulating part.

[0021] 3. In the above scheme, the first and second adjustment parts installed inside the adjustment cavity are equidistant and perpendicular. The beam of sunlight generated by the outside world passes through the first adjustment part to one side of the second adjustment part and finally shines on the surface of the photovoltaic panel, generating light. The light generated by the beam of sunlight shining on one side of the photovoltaic panel is diffused to the surface of the second reflector located on one side of the photovoltaic panel. The surface of the second reflector is provided with a reflective layer. The beam of sunlight shining on the surface of the photovoltaic panel is diffused to the surface of the reflective layer on one side of the second reflector, and the beam is reflected to the other side of the photovoltaic panel for reflective power generation. This fully utilizes the light, ensures the light intensity, and provides an excellent irradiation environment for the photovoltaic panel to generate electricity, thus ensuring the amount of electricity generated.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] refer to Figure 1-9 The light pollution control device for a photovoltaic generator set shown includes a mounting base 1, an adjustment cavity 2, and a light-collecting part 3. The adjustment cavity 2 is fixedly installed on one side of the mounting base 1. The light-collecting part 3 is provided on one side of the adjustment cavity 2. A light-transmitting element 31 is installed inside the adjustment cavity 2. The light-transmitting element 31 has an inclined structure and one side is installed against the inner wall of the adjustment cavity 2. A first adjustment part 32 is fixedly installed inside the adjustment cavity 2. One side of the light-transmitting element 31 and one side of the first adjustment part 32 are opposite to each other and a gap is left.

[0036] In this embodiment, one side of the first adjusting part 32 is installed against the inner wall of the adjusting cavity 2. A second adjusting part 33 is slidably installed inside the adjusting cavity 2. One side of the second adjusting part 33 is opposite to one side of the first adjusting part 32, with a gap between them. A photovoltaic panel 35 is installed inside the adjusting cavity 2. The photovoltaic panel 35 is perpendicular to the inner side of the light-receiving part 3. A sliding column 21 is slidably installed inside the photovoltaic panel 35. The photovoltaic panel 35 is a double-sided receiving power generation structure.

[0037] A photovoltaic panel 35 is fixedly installed on one side of the surface of the sliding column 21. A second reflector 36 is installed inside the adjustment cavity 2. A reflective layer is provided on one side of the second reflector 36. The reflective layer on one side of the surface of the photovoltaic panel 35 and the second reflector 36 abuts against each other. A lifting member 24 is slidably installed inside the second reflector 36. One side of the sliding column 21 is fixedly installed through the sliding connecting rod 26 and the lifting member 24. A compression member 25 is evenly arranged on one side of the lifting member 24. The sliding connecting rod 26 is connected to one side of the lifting member 24. A sliding groove 27 is opened on the side wall of the adjustment cavity 2. The sliding connecting rod 26 slides through the second reflector 36 and the side wall of the adjustment cavity 2 and abuts against one side of the first adjustment part 32. One side of the compression member 25 abuts against one side inside the second reflector 36, and the other side abuts against the other side of the lifting member 24. A first reflector 34 is installed on one side of the sliding column 21.

[0038] In the above scheme, when the photovoltaic panel 35 needs to generate electricity through sunlight, external sunlight first shines into the interior of the regulating cavity 2 through the light-receiving part 3, and then shines on the surface of the light-transmitting element 31 located inside the regulating cavity 2. The beam of light generated by the sunlight passes through the light-transmitting element 31 and then shines on one side of the first regulating part 32 opposite to the light-transmitting element 31. The light-transmitting element 31 is a double-sided light-transmitting mirror. When the beam of sunlight shines on one side of the light-transmitting element 31 and passes through, the beam of light on the other side will not be refracted. On the outside of the light-transmitting element 31, beam redundancy will occur, producing a dazzling beam of light. The beam of sunlight passes through the light-receiving part 3... The sunlight shines on one side of the first reflector 34 located inside the regulating cavity 2, producing a mirror refraction phenomenon. The light beam of the outside sunlight is refracted to one side of the first regulating part 32, and the light beam of the first regulating part 32 itself is scattered by the light-transmitting element 31 to suppress the refraction, so as to ensure the penetration of the outside light beam into the first regulating part 32. At this time, the first regulating part 32 and the second regulating part 33 installed inside the regulating cavity 2 are equidistant and perpendicular. The light beam generated by the outside sunlight passes through the first regulating part 32 to one side of the second regulating part 33, and finally shines on the surface of the photovoltaic panel 35 to generate light, and the photovoltaic panel 35 is used for power generation.

[0039] Sunlight beams from the outside world shine on one side of the photovoltaic panel 35, and the resulting light is diffused to the surface of the second reflector 36 located on one side of the photovoltaic panel 35. The surface of the second reflector 36 is provided with a reflective layer. The sunlight beams shining on the surface of the photovoltaic panel 35 are diffused to the surface of the reflective layer on one side of the second reflector 36, and the beams are reflected to the other side of the photovoltaic panel 35 for reflected power generation. This makes full use of the light, ensures the light intensity, and provides an excellent irradiation environment for the photovoltaic panel 35 to generate electricity, thus ensuring the power output of the photovoltaic panel 35.

[0040] As the sunlight beams are reflected by the second reflector 36, the mirror structure of the photovoltaic panel 35 and the reflective layer on one side of the second reflector 36 also reflect the light. A large amount of heat radiation from the sunlight accumulates between one side of the photovoltaic panel 35 and the reflective layer, radiating heat to the second reflector 36 itself. The interior of the second reflector 36 generates corresponding heat, which heats the temperature of the second reflector 36. During the heating process of the second reflector 36, the compression member 25 installed inside the second reflector 36 expands due to the heat from the second reflector 36. This expands and then comes into contact with the lifting member 24 installed on one side of the compression member 25, causing equidirectional movement with the expansion of the compression member 25. This, in turn, drives the sliding connecting rod 26 installed on one side of the lifting member 24 to move in the same direction.

[0041] The regulating cavity 2 has a sliding groove 27 on its side wall. A sliding connecting rod 26 passes through the second reflector 36 and slides within the sliding groove 27, abutting against one side of the first regulating part 32. When the lifting member 24 moves due to the thermal expansion of the compression member 25, it causes the sliding connecting rod 26 to move equidirectionally along the vector direction of the compression member 25's expansion. This, in turn, causes the first regulating part 32, installed inside the regulating cavity 2, to move equidirectionally along the sliding groove 27. The gap between the first adjustment part 32 and the second adjustment part 33 gradually shortens, thereby causing the beam of sunlight in the outside to diffuse into one side of the photovoltaic panel 35 in a variable diameter shape. This increases the heat-receiving area of ​​the photovoltaic panel 35 while preventing the reflection of light from the second reflector 36 and the accumulation of a large amount of heat between the photovoltaic panel 35 and one side of the photovoltaic panel 35, which would damage the photovoltaic panel 35. The lifting member 24 moves to one side of the sliding column 21 through the compression member 25 and abuts against the sliding column 21, causing the interior of the sliding column 21 to slide, thereby causing the photovoltaic panel 35 to change position.

[0042] One side of the photovoltaic panel 35 is away from the side of the reflective layer on the surface of the second reflector 36. While increasing the spatial distance between the second reflector 36 and the photovoltaic panel 35, the position of the first reflector 34 on the other side of the sliding column 21 is changed. This ensures that the beam of sunlight generated by the outside world is always refracted and reflected inside the regulating cavity 2. This reduces the need for large-area photovoltaic panels 35 to block sunlight from hitting the water surface, lowers the water temperature and affects the photosynthesis of phytoplankton in the water, and increases the concentration of dissolved oxygen in the water. This solution does not require the design of a large base frame to affect the environment in the water, increases the diversity of the ecological environment in the water, and ensures the normal natural development of the ecological environment in the water.

[0043] As a preferred embodiment, the adjustment cavity 2 has a hollow cone-shaped structure, and the number of light-transmitting elements 31 is four. These elements are inclined and face one side of the first adjustment part 32, ensuring that the light beams of sunlight passing through the light-transmitting elements 31 are always perpendicular to the first adjustment part 32. The number of the first adjustment parts 32 is adapted to the number of light-transmitting elements 31. The number of the second adjustment parts 33 changes with the number of the first adjustment parts 32. The installation space and installation environment are not limited in detail in this solution. The installation conditions are limited based on the number of the second adjustment parts 33 and the first adjustment parts 32 installed.

[0044] In a preferred embodiment, the angle of inclination of the light-transmitting element 31 and the sum of the radii between the second adjustment part 33 and the first reflector 34 ensure that the reflection distances of the first reflector 34 and the second adjustment part 33 are equal.

Each first adjustment part 32 and the second adjustment part 33 form a group. The second adjustment part 33 moves relative to the first adjustment part 32 and adjusts the distance between the second adjustment part 33 and the first adjustment part 32.

The compression member 25 expands when heated, and the expansion amount increases linearly with the increase of temperature.

One side of the sliding column 21 is slidably installed inside the sliding cavity 22, wherein the sliding cavity 22 is a sliding assembly structure.

The first connecting member 6 is installed on one side of the photovoltaic panel 35 through the locking member 5. The number of photovoltaic panels 35 installed varies with the number of second adjustment parts 33. The locking member 5 is a detachable threaded assembly structure, which facilitates the quick installation and fixing of the photovoltaic panel 35 by the installer.
