Description

Technical Field

[0001] The utility model relates to the technical field of tunnels, in particular to a photovoltaic power generation shading shed for tunnels with adjustable brightness. Background Art

[0002] Since the brightness inside the tunnel is significantly lower than that outside the tunnel, which leads to the black hole effect and white hole effect, the method of arranging enhanced lighting at the entrance and exit of the tunnel is often used to alleviate it. However, turning on enhanced lighting consumes a lot of energy every year. In order to alleviate the energy consumption of tunnel lighting, it is proposed to set up a sunshade at the entrance of the tunnel, using sunlight to achieve a smooth transition from the brightness outside the tunnel to the brightness inside the tunnel, thereby reducing operating energy consumption. Some of the existing sunshade solutions use the reasonable arrangement of translucent films or translucent panels to gradually reduce the light intensity, but these materials are prone to reduced transmittance after long-term use, and it is difficult to ensure that the environment meets the regulatory requirements for a long time; the other part uses concrete or steel structure beams at a certain distance to block the light, but this kind of sunshade will leave alternating light and dark grating patterns on the road surface, which is easy to produce uncomfortable glare and affect the driving comfort of drivers.

[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0024] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a photovoltaic power generation awning for tunnels with adjustable brightness, including: a frame 1, a plurality of light-transmitting power generation glasses 2, a battery 3, a plurality of lighting fixtures 5 and a blocking device 6. The outline of the frame 1 is consistent with the outline of the tunnel, extending outward from the tunnel entrance. A plurality of light-transmitting power generation glasses 2 are fixed to the outer surface of the frame 1 and cover the entire outer surface of the frame 1. The battery 3 is connected to the light-transmitting power generation glasses 2 through a transmission line 4. A plurality of lighting fixtures 5 are respectively installed in the tunnel and on the inner surface of the frame 1, and the lighting fixtures 5 are connected to the battery 3 through a transmission line 4. The blocking device 6 is connected to one end of the frame 1 close to the tunnel entrance, and the blocking device 6 forms an angle with the frame 1. The angle can quickly reduce the kinetic energy of falling rocks and more effectively intercept falling rocks in a larger range. At the same time, it can allow sunlight to shine on the light-transmitting power generation glass 2 along the angle without affecting the power generation efficiency of the light-transmitting power generation glass 2 below the blocking device 6.

[0026] The light-transmitting power-generating glass 2 is used to convert light energy into electrical energy and store it in the storage battery 3 through the transmission line 4. When the brightness inside the sunshade shed is low due to insufficient or uneven external lighting, the storage battery 3 can be used to supply energy to the lighting fixtures 5 through the transmission line 4 to meet the lighting needs and reduce energy consumption, thereby reducing carbon emissions during the operation of the tunnel. The excess electricity can also be supplied to the ventilation and lighting system inside the tunnel.

[0027] The storage battery 3 should be arranged near the tunnel entrance to facilitate the storage and utilization of electric energy. In addition to conventional electrochemical energy storage devices such as lithium batteries, energy storage methods such as pumped water storage and compressed air storage can also be selected in combination with on-site power generation conditions and energy storage needs.

[0028] The blocking device 6 includes a frame 61 and a blocking net 62; the frame 61 includes two arc beams and multiple straight beams; the curvature of one of the arc beams is consistent with the curvature of the tunnel contour and is connected to the end of the skeleton 1 close to the tunnel entrance; the curvature of the other arc beam is greater than the curvature of the tunnel contour and is installed above the skeleton 1 through the straight beams at both ends; the two ends of the multiple straight beams are respectively connected to two arc beams to form a triangular truss; the blocking net 62 fits the frame 61. The frame 61 is made of high-strength metal, which is not easy to deform and is used to withstand the impact load caused by falling rocks. The blocking net 62 is made of elastic material, which is fixed to the frame 61 after prestressing, and can bounce off falling rocks or make them roll away from the top of the sunshade along the slope of the blocking device 6.

[0029] The skeleton 1 is made of light and high-strength material. The skeleton 1 includes a plurality of arch supports 11 and a plurality of horizontal cross bars 12. The shape of the arch supports 11 is consistent with the shape of the tunnel entrance. The plurality of arch supports 11 are arranged in parallel at equal intervals at the tunnel entrance and connected by a plurality of horizontal cross bars 12. The bottom of the arch supports 11 is fixed in the roadbed. The horizontal cross bars 12 provide an installation position for the lighting fixtures 5 while enhancing the structural stability. The plurality of lighting fixtures 5 are arranged at equal intervals on the arch top or the arch waists on both sides of the tunnel and the skeleton 1.

[0030] like Figure 3 As shown, the arch support 11 and the horizontal cross bar 12 intersect to form a rectangular grid structure.

[0031] The light transmittance of the plurality of light-transmitting power generation glasses 2 gradually decreases as the distance between the light-transmitting power generation glasses 2 and the tunnel entrance decreases. When the plurality of lighting fixtures 5 arranged on the frame 1 are turned on, their brightness gradually decreases from the side far from the tunnel entrance to the side close to the tunnel entrance. These settings are to achieve a smooth transition from the external light environment to the light environment inside the tunnel.

[0032] The transmission line 4 is arranged along the frame 1 and buried inside the frame 1 to prevent the transmission line 4 from being directly exposed to the outside and causing rapid aging of the transmission line 4.

[0033] A photosensitive sensor is provided inside the sunshade, and the photosensitive sensor is electrically connected to the lighting fixture 5 and the battery 3. When the brightness in the sunshade is insufficient, the photosensitive sensor controls the lighting fixture 5 to turn on and controls the brightness of the lighting fixture 5 to reach the lighting requirement.

[0034] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
