Description

Technical Field

[0001] The present invention relates to the technical field of green lighting, and in particular to a solar-assisted ventilation light guide tube for underground garages. Background Art

[0002] Due to its special environmental characteristics, such as unattended operation, large space, low floor height, poor air circulation, and insufficient natural lighting, underground parking lots often rely on a large number of 24-hour uninterrupted ventilation and lighting equipment. Although the rapid development of intelligent energy-saving systems in recent years has significantly reduced energy consumption, the power consumption cost of underground garages is still relatively high during peak hours, especially when they are frequently used during the day. In addition, due to their underground location, the air circulation in underground garages is usually poor, forming an environment similar to "stagnant water". This poor air circulation can cause harmful gases to be released from parked cars for a long time, seriously affecting air quality and posing a potential threat to human health. In addition, poor air circulation is also likely to cause moisture accumulation in the garage, which may lead to rusting of metal parts, rotting of wood, and even damage to stored items. Using fans to force ventilation in underground garages results in high electricity costs. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a solar-assisted ventilation light guide tube for underground garages, so that after the external sunlight enters the heating tube, through the reflection of the one-way reflective film, the sunlight can be reflected to the middle of the heating tube, generating a large amount of heat energy. This heat energy can stimulate the "chimney effect", prompting the air in the heating tube to flow upward, realizing rapid ventilation in the garage; it can also conduct sunlight downward into the lower light guide tube to achieve natural lighting for the underground garage.

[0004] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0005] A solar-assisted ventilation light guide tube for underground garages, comprising:

[0006] A heating tube with an open top, and a transparent concentrating ring with a triangular cross-section is arranged along the circumferential direction on the inner side of the tube wall. The outer surface of the transparent concentrating ring is coated with a one-way reflective film for concentrating light in the middle of the heating tube to generate heat energy;

[0007] A light guide tube with its top connected to the heating tube and a ventilation hole provided at the bottom. The inner diameter of the light guide tube is smaller than that of the heating tube, and a diffuse reflection tube is provided near the bottom inside the light guide tube. Both the light guide tube and the heating tube have transparent tube walls.

[0008] As a further implementation method, a tube cap is provided at the top of the heating tube wall through a support rod.

[0009] As a further implementation method, the bottom end of the heating cylinder is an inverted frustum structure for connecting the light guide cylinder.

[0010] As a further implementation method, a waterproof cap is provided at the bottom end of the frustum structure for covering the top end of the light guide cylinder and abutting against the waterproof platform of the underground garage roof.

[0011] As a further implementation method, the transparent light concentrator includes a top plane, a bottom inclined plane and an outer side surface, wherein the one-way reflective film on the top plane and the outer side surface allows sunlight to enter the transparent light concentrator, and the bottom inclined plane is attached to the light incident surface of the one-way reflective film.

[0012] As a further implementation method, the transparent light concentrator extends to the inner top end of the light guide cylinder, and the diffuser cylinder is located below the transparent light concentrator.

[0013] As a further implementation method, the diffuser cylinder is made of transparent plastic material with openings at the top and bottom ends.

[0014] As a further implementation method, metal particles, reflective particles and hollow particles are provided on the inner wall of the diffuser cylinder.

[0015] As a further implementation method, the ventilation hole is provided on the side wall of the bottom end of the light guide cylinder.

[0016] As a further implementation method, the ventilation hole is located below the diffuser cylinder.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. On the inner side surface of the wall of the heating cylinder of the present invention, a transparent light concentrator with a triangular cross-section is arranged circumferentially, and the outer surface of the transparent light concentrator is coated with a one-way reflective film. After the external sunlight enters the heating cylinder, through the reflection of the one-way reflective film, the sunlight can be reflected to the middle of the heating cylinder, generating a large amount of heat energy. This heat energy can stimulate the "chimney effect", prompting the air in the heating cylinder to flow upward, and at the same time forming a negative pressure below the heating cylinder, thereby accelerating the upward discharge of air and realizing rapid ventilation in the garage; it can also conduct sunlight downward into the lower light guide cylinder. The inner side of the light guide cylinder is provided with a diffuser cylinder, and after the sunlight is diffusely reflected, natural lighting of the underground garage is realized.

[0019] 2. The inner diameter of the heating cylinder of the present invention is larger than the inner diameter of the light guide cylinder, which helps to increase the upward speed of the air at the light guide cylinder during the process of air rising and discharging, thus having the effect of accelerating exhaust.

[0020] 3. The inner wall of the diffuser cylinder of the present invention is provided with metal particles, reflective particles and hollow particles, which are irregularly distributed, improving the diffuse reflection effect.

[0021] 4. The cross-section of the transparent light-gathering ring of the present invention is triangular. The one-way reflective film on the top plane and the outer side surface of the transparent light-gathering ring allows sunlight to enter the transparent light-gathering ring. The bottom inclined surface is attached to the light incident surface of the one-way reflective film, so that not only the sunlight has an effect of converging towards the middle, but also the effect of guiding the sunlight downward into the underground garage can be achieved.

[0022] 5. The present invention is provided with a waterproof cap, which is used to cover the top end of the light guide tube and abut against the waterproof platform of the underground garage roof to achieve waterproofing and prevent rainwater from entering the underground garage through the gap between the auxiliary ventilation light guide tube and the underground garage roof.

[0031] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanations of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0032] Embodiment 1

[0033] In a typical embodiment of the present invention, with reference to Figures 1 - 5 as shown, a solar-assisted ventilation light guide tube for an underground garage includes a heating tube 3 and a light guide tube 5. The heating tube 3 is used for concentrating light to form a chimney effect, heating the gas inside the tube, increasing the temperature inside the tube, causing the air flow to rise, accelerating ventilation, and the light guide tube 5 is used for diffusely reflecting light and guiding it into the garage to achieve lighting and save the electricity cost of the garage.

[0034] As Figure 1 and Figure 2 shown, the heating tube 3 and the light guide tube 5 are connected. The heating tube is located at the top end of the light guide tube 5, and the bottom end of the light guide tube 5 is used to extend into the underground garage. When the temperature in the heating tube 3 rises, it promotes the upward flow of the air in the heating tube 3, forming a negative pressure below the heating tube 3, thereby accelerating the upward discharge of the air.

[0035] As Figure 1 shown, the top end of the heating tube 3 is open, and a tube cap 1 is provided at the top end of the tube wall of the heating tube 3 through a support rod 2, which is used to block rain and prevent impurities from entering the tube and affecting the light guiding and heating effects.

[0036] The bottom end of the heating tube 3 is an inverted frustum structure for connecting the light guide tube. Therefore, the inner diameter of the heating tube 3 is larger than the inner diameter of the light guide tube 5. In this way, during the process of the air rising and discharging, it helps to increase the rising speed of the air at the light guide tube 5, thus having the effect of accelerating the exhaust.

[0037] The bottom end of the light guide tube 5 is conical, and ventilation holes are uniformly arranged along the circumferential direction on the side surface of the bottom end. During ventilation, the gas in the underground garage enters the interior of the light guide tube 5 from here.

[0038] As Figures 1 - 3 shown, for the solar-assisted ventilation light guide tube of the underground garage in this embodiment, when applied to the underground garage, waterproofing needs to be considered to prevent rainwater from entering the underground garage through the gap between the auxiliary ventilation light guide tube 5 and the underground garage roof 11.

[0039] A waterproof cap 4 is provided at the bottom end of the frustum structure, which is used to cover the top end of the light guide tube 5 and abut against the waterproof platform of the underground garage roof. When installing this device, a waterproof platform is provided on the outer top surface of the underground garage roof 11 for waterproofing. The light guide tube 5 is inserted into the middle position of the waterproof platform and the opening of the underground garage roof 11. The waterproof cap is frustum-shaped and presses on the waterproof platform 10 for waterproofing.

[0040] It can be understood that the barrel walls of the heating barrel 3 and the light guide barrel 5 in this embodiment are both transparent barrel walls 7. A transparent light collecting ring 8 with a triangular cross-section is arranged circumferentially on the inner side surface of the barrel wall of the heating barrel 3. The outer surface of the transparent light collecting ring 8 is coated with a one-way reflective film, which is used to concentrate light in the middle of the heating barrel to generate heat energy. A diffuse reflection barrel is provided near the bottom end position in the light guide barrel, which is used to diffusely reflect sunlight and guide it into the garage.

[0041] As Figure 2 shown, in order to improve the ventilation effect, the transparent light collecting ring 8 in this embodiment extends to the top end inside the light guide barrel. The diffuse reflection barrel is located below the transparent light collecting ring and is nested with the light guide barrel 5. The ventilation hole 6 is located below the diffuse reflection barrel.

[0042] To ensure the light collection effect inside the heating barrel 3, as Figure 2 shown, the transparent light collecting ring is made of transparent plastic material, and its cross-section is a right triangle structure. It is arranged in a ring shape on the inner wall of the heating barrel 3 and is evenly distributed along the axial direction of the barrel wall, extending from the top end of the heating barrel 3 to the top end of the light guide barrel 5. The shorter right-angled side of the right triangle structure fits with the barrel wall, the longer right-angled side is perpendicular to the barrel axis, the plane where the longer right-angled side is located is used as the top plane, the plane where the shorter right-angled side is located is used as the outer side surface, and the plane where the hypotenuse is located is used as the bottom inclined surface. At the inverted frustum structure at the bottom end of the heating barrel, the plane where the hypotenuse of the triangle is located is used as the top plane.

[0043] The transparent light collecting ring in this embodiment includes a top plane, a bottom inclined surface and an outer side surface. A one-way reflective film 12 is coated on the outer surface of the transparent light collecting ring, and the one-way reflective film 12 allows sunlight to pass through unidirectionally.

[0044] As Figure 4 shown, the light incident surface of the one-way reflective film on the top plane and the outer side surface faces outward, and the reflective surface fits with the transparent light collecting ring, allowing sunlight to enter the transparent light collecting ring 8. The bottom inclined surface of the transparent light collecting ring 8 fits with the light incident surface of the one-way reflective film 12, and the reflective surface faces outward, allowing sunlight to pass through from the inside to the outside.

[0045] By setting the transparent light collecting ring 8 and the one-way reflective film 12, when external sunlight enters the heating barrel, after being reflected by the one-way reflective film, the sunlight can be reflected to the middle of the heating barrel, generating a large amount of heat energy. This heat energy can stimulate the "chimney effect", prompting the air inside the heating barrel 3 to flow upward, and at the same time forming a negative pressure below the heating barrel 3, thereby accelerating the upward discharge of air. The transparent light collecting ring 8 and the one-way reflective film 12 have a locking effect on sunlight.

[0046] Since a one-way light guide film 12 is adopted inside the heating cylinder, it can lock the sunlight and guide it downward into the lower light guide cylinder 5. A diffusing cylinder 9 is arranged inside the light guide cylinder 5. The diffusing cylinder is made of transparent plastic 16 and has openings at the top and bottom for diffusely reflecting sunlight.

[0047] The inner wall of the diffusing cylinder 9 is provided with metal particles 13, reflective particles 14 and hollow particles 15. The sunlight entering the light guide cylinder is evenly reflected into the internal space of the underground garage through the diffusing cylinder 9, thereby providing natural lighting.

[0048] As Figure 5 shown, the metal particles 13, reflective particles 14 and hollow particles 15 are arranged inside the transparent plastic 16, densely distributed, and the relative distribution order among the metal particles 13, reflective particles 14 and hollow particles 15 is disrupted, showing a mixed distribution state.

[0049] The transparent plastic 16 is selected as acrylic material. Before the transparent plastic 16 is fixed and formed, metal particles 13 and reflective particles 14 are added to the inner side, and air is filled to form hollow particles 15.

[0050] Both the metal particles 13 and the reflective particles 14 are irregular in shape, making the inner wall surface of the diffusing cylinder 9 a rough surface, and the light is reflected disorderly in all directions. By providing metal particles 13, reflective particles 14 and hollow particles 15 on the inner wall of the diffusing cylinder 9, the diffuse reflection of sunlight is realized, enabling the underground garage to use the imported sunlight for natural lighting.

[0051] This design not only reduces the dependence on artificial lighting and lowers energy consumption, but also improves the air quality in the underground garage through natural ventilation, achieving the dual goals of energy conservation and environmental improvement.

[0052] The solar ventilation and light guide cylinder of the underground garage in this embodiment is embedded in the underground garage roof 11. This design structure is simple and convenient for construction. During the day, when the sunlight is sufficient, the system can effectively promote the air circulation in the underground garage and use the imported sunlight for natural lighting. This solar energy utilization scheme not only improves the air circulation efficiency but also reduces energy consumption, achieving the dual benefits of energy conservation and environmental protection.

[0053] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
