Description

Technical Field

[0001] The present invention belongs to the technical field of building curtain walls, and specifically provides an energy-saving decorative wall panel. Background Art

[0002] A curtain wall is a common structural form of the exterior wall panel of a building, which is used to achieve the exterior wall enclosure of the building and play a decorative role, but does not bear the load. It is a common lightweight wall used in large or high-rise buildings.

[0003] In related technical solutions, a unitized double-glass curtain wall is used as the wall panel for external enclosure. Specifically, the wall panel here includes a frame and an outer curtain wall glass and an inner curtain wall glass embedded and installed in the frame. A sandwich layer is formed between the outer curtain wall glass and the inner curtain wall glass to reduce the transfer of heat on both sides of the curtain wall, thereby achieving the effect of energy conservation. In order to make full use of external light, a photovoltaic panel in a structure similar to a shutter is generally provided in the middle of the sandwich layer.

[0004] The inventor has learned that in the above solution, the external sunlight irradiates on the photovoltaic panel after passing through the outer curtain wall glass for power generation. However, the intensity of external light shows the characteristics of strong light in summer, weak light in winter, strong light at noon, and weak light in the morning and evening. That is to say, the power generation power of the photovoltaic panel is relatively low in winter and in the morning and evening, and it is not convenient to further improve its power generation power. Summary of the Invention

[0005] The purpose of the present invention is to provide an energy-saving decorative wall panel that can solve at least one of the above technical problems.

[0006] To solve the above problems in the prior art, one or more embodiments of the present invention provide an energy-saving decorative wall panel for forming the outer curtain wall of a building. The wall panel includes a frame, in which an inner curtain wall glass and an outer curtain wall glass are embedded, and a sandwich layer is defined between the two. A plurality of horizontally extending photovoltaic panels are installed in the sandwich layer, and the plurality of photovoltaic panels are arranged in sequence in the middle of the sandwich layer in the up and down direction.

[0007] The inner curtain wall glass is a plano-concave lens, and the concave surface of the plano-concave lens faces the sandwich layer. The outer curtain wall glass includes a plane mirror. A moving seat is provided at the center of the side of the plane mirror close to the sandwich layer. A plurality of elastic telescopic rods are installed around the moving seat. One end of the telescopic rod is hinged to the moving seat, and the other end is hinged to the frame. A horizontal linear driving member is provided between the moving seat and the concave surface of the plano-concave lens. A limiting space is defined between the telescopic rod and the plane mirror, and a transparent water bag that can be filled with water and has elasticity is filled in the limiting space. The linear driving member can stretch and contract to make the moving seat translate and change the angle between the telescopic rod and the plane mirror, so that the water bag forms a plano-convex lens structure with adjustable focal length.

[0008] Further, one side of the water bag is attached to and fixed to the outer curtain wall glass. A plurality of elastic limiting columns are fixed on the side wall of the middle rod sleeve of the telescopic rod. The side surface of the water bag facing the interlayer has a plurality of concave limiting grooves, and the limiting columns are embedded in the limiting grooves.

[0009] Further, two columns of photovoltaic panels are arranged vertically. Along the width direction of the wall panel, the two columns of photovoltaic panels are respectively on both sides of the linear driving member. The upper end of the frame has a receiving cavity, and a plurality of photovoltaic panels can be lifted and lowered vertically to be stacked and stored in the receiving cavity.

[0010] Further, the receiving cavity is square, and the depth of the receiving cavity is greater than the height after the photovoltaic panels in a column are stacked.

[0011] Further, an air inlet is provided at the lower end of the frame, and an air outlet is provided at the upper end. A spray hole that can be independently opened and closed is provided on the side of the water bag facing the interlayer, and the spraying direction of the spray hole faces the photovoltaic panel.

[0012] Further, at least two columns of spray holes are arranged vertically downward, and both ends of each photovoltaic panel in the horizontal direction are respectively aligned with one of the spray holes. The photovoltaic panel is a bent plate with a higher middle and lower sides, and the included angle between the two parts of the bent plate is 165° - 175°.

[0013] Further, a fan is installed at the air inlet and / or the air outlet. Each photovoltaic panel can be rotated to face downward with the light-receiving surface to be aligned with the flowing direction of the air flow.

[0014] Further, brackets are respectively installed around the inner wall of the frame. One end of the telescopic rod is hinged to the bracket, and the telescopic rod is an elastic rod. The outer contour of the moving seat is cylindrical, and a plurality of installation grooves are evenly arranged on the outer circumferential side of the moving seat. The other end of the telescopic rod is hinged in the installation groove.

[0015] Further, the moving seat includes an elastic part and a rigid part that are fixedly connected. The rigid part is hinged to the telescopic rod, and the elastic part is on the side close to the water bag to abut against the water bag.

[0016] Further, the water bag is communicated with an indoor water tank. The indoor water tank includes a cold water storage tank and a hot water storage tank. The cold water storage tank is communicated with the rainwater collection component of the building. The water inlet of the water bag is communicated with the cold water storage tank, and the water outlet of the water bag is communicated with the hot water storage tank.

[0017] The beneficial effects of the above one or more technical solutions:

[0018] First of all, the photovoltaic panels are arranged in the middle of the curtain wall interlayer. This setting method enables part of the light to still enter the room through the gaps between the frame and the photovoltaic panels and between adjacent photovoltaic panels, and the glass curtain wall will not lose the ability to provide light to the interior of the building.

[0019] In this solution, the outer curtain wall glass is a plano-convex lens. The four sides of the moving seat are hinged to one end of the telescopic rod, and the other end of the telescopic rod is hinged to the frame. This setting method facilitates the formation of a limiting space with a thick middle and thin edges by using the moving seat and multiple telescopic rods, thereby limiting the deformation direction of the water bag, so as to make the transparent water bag form a convex lens structure with a thick middle and thin edges. That is to say, at this time, the convex lens structure of the water bag itself focuses the light at the outer glass curtain wall on the photovoltaic panel in the middle of the interlayer, increasing the light intensity on the photovoltaic panel to improve the luminous efficiency of the photovoltaic panel.

[0020] Moreover, the moving seat can move horizontally to change the angle between the telescopic rod and the outer glass curtain wall, change the thickness difference between the middle position and the edge position of the limiting space, and thus adjust the light-gathering ability of the water bag. During the process of seasonal changes and the rise and fall of the sun, by adjusting the convexity degree of the water bag facing the interlayer side, the light-gathering effect of the water bag is adjusted. While ensuring the power generation power of the photovoltaic panel, it can also prevent the convex lens structure of the water bag from over-focusing light, and avoid the strong light and temperature from affecting the expected service life of the photovoltaic panel.

[0021] When the telescopic rod is an elastic rod, during the expansion process of the water bag, the telescopic rod will bend to a certain extent, so that the side of the water bag close to the interlayer forms a curved surface, which is convenient for better realizing the light-gathering effect.

[0022] In addition, in this solution, the inner curtain wall glass is a plano-concave lens. The plano-concave lens can refract and disperse the light in the interlayer again, so that the light evenly enters the room from the inner curtain wall glass, avoiding the probability of uneven light entering the room from the inner curtain wall glass caused by the light-gathering effect of the water bag, and improving the uniformity of the light entering the room.

[0040] Embodiment 1

[0041] As Figures 1 - 5 shown, an energy-saving decorative wall panel provided in this embodiment is used to form the outer curtain wall of a building. The wall panel includes a frame 5, in which an inner curtain wall glass 3 and an outer curtain wall glass 9 are embedded, and a sandwich layer 15 is defined between the two. A plurality of laterally extending photovoltaic panels 14 are installed in the sandwich layer 15, and the plurality of photovoltaic panels 14 are arranged in the middle of the sandwich layer 15 in the up and down direction in sequence.

[0042] Specifically, the energy-saving decorative wall panel of this embodiment is installed between the floor slab and the ceiling slab of the building. At this time, the upper end of the frame 5 is fixed to the ceiling slab, and the lower end of the frame 5 is supported and fixed by the floor slab, that is to say, the height of the above-mentioned energy-saving decorative wall panel is basically the same as the height of each floor of the building. In some other embodiments, two or three or more rows of wall panels can be arranged and spliced between the floor and the ceiling of each floor of the building for enclosure.

[0043] Specifically, the frame 5 here is a square frame. The frame 5 includes a top beam and a bottom beam arranged horizontally, and the top beam and the bottom beam are fixedly connected by two vertical beams. More specifically, 45-degree bevel cuts are respectively provided at both ends of the top beam, the bottom beam, and the vertical beams, so as to facilitate the splicing of the top beam, the bottom beam, and the vertical beams. More specifically, at least two plug-in slots (not shown in the figure) are provided on the inner wall of the frame 5, and the two plug-in slots are respectively used to realize the plug-in limit and fixation of the inner curtain wall glass 3 and the outer curtain wall glass 9. At this time, the frame 5 also cooperates with the inner curtain wall glass 3 and the outer curtain wall glass 9 to enclose the above-mentioned sandwich layer 15. In addition, a plurality of connecting brackets 4 are installed at one end of the frame 5 away from the outer curtain wall glass 9, and the connecting brackets 4 here are used to connect the support structure of the outer wall of the building.

[0044] It should be noted that the above-mentioned interlayer 15 can be in a vacuum state or a ventilation state. When in a winter environment, in order to reduce heat dissipation, the interlayer 15 is in a vacuum state. The interlayer 15 in a vacuum state can greatly reduce the probability of heat loss through the inner curtain wall glass 3 to the outer curtain wall glass 9, thereby achieving the effect of heat insulation of the wall panel. When in a summer environment, in order to avoid the heat of the outer curtain wall glass 9 being transferred to the inner curtain wall glass 3 due to long-term sunlight irradiation, the interlayer 15 is set to a ventilation state, and the flow of air in the interlayer 15 takes away the heat on the outer curtain wall glass 9 to achieve a cooling effect.

[0045] Specifically, each photovoltaic panel 14 extends horizontally, and a plurality of photovoltaic panels 14 are arranged in sequence in the middle of the interlayer 15 in the up and down direction. As a specific structural form, the photovoltaic panels 14 are installed in the interlayer 15 through traction lines in a row, so that the photovoltaic panels 14 form a structure similar to a shutter.

[0046] In the case where the telescopic rod 10 is an elastic rod, during the expansion of the water bladder 11, the telescopic rod will bend to a certain extent. In particular, the telescopic rod bends outward from its middle, so that the side of the water bladder close to the interlayer forms a curved surface, which is convenient for better realizing the light concentration effect.

[0047] It can be known that when the photovoltaic panels 14 are arranged in the middle of the interlayer 15, the light rays irradiating on the middle of the interlayer 15 will be blocked by the photovoltaic panels 14, and the gaps between adjacent photovoltaic panels 14 and the gaps between the photovoltaic panels 14 and the inner wall of the frame 5 can still transmit light, so that the wall panel in this embodiment can still serve the function of transmitting light and illuminating.

[0048] In this embodiment, the inner curtain wall glass 3 is a plano-concave lens, and the concave surface of the plano-concave lens faces the interlayer 15. The outer curtain wall glass 9 includes a plane mirror. A moving seat 1 is provided at the center of the side of the plane mirror close to the interlayer 15. A plurality of telescopic rods 10 are installed around the moving seat 1. One end of the telescopic rod 10 is hinged to the moving seat 1, and the other end is hinged to the frame 5. A horizontal linear drive member 2 is provided between the moving seat 1 and the concave surface of the plano-concave lens. A limiting space 16 is defined between the telescopic rod 10 and the plane mirror, and the limiting space 16 is filled with a transparent water bladder 11 that can be filled with water and is elastic. The linear drive member 2 can be telescoped to make the moving seat 1 translate and change the angle between the telescopic rod 10 and the plane mirror, so that the water bladder 11 forms a plano-convex lens structure with adjustable focal length.

[0049] The above-mentioned water bag 11 can be made of transparent silica gel material. Utilizing the elastic deformable characteristics of the silica gel material, filling the water bag 11 with different amounts of water can cause the water bag 11 to expand elastically to different sizes. When the water bag 11 drains water, it retracts under the action of elasticity. One side of the above-mentioned water bag 11 is limited by the outer curtain wall glass 9, and the other side is limited by the telescopic rod 10. That is to say, the water bag 11 expands within the limiting space 16 formed by the outer curtain wall glass 9 and multiple telescopic rods 10. Further, one end of the telescopic rod 10 is hinged to the moving seat 1, and the other end is hinged to one end of the inner wall of the frame 5 close to the outer curtain wall glass 9; this enables the telescopic rod 10 and the outer curtain wall glass 9 to be arranged at an angle, and further the limiting space 16 is a space with a thick middle and thin edges, which is convenient for defining the water bag 11 with a thick middle and thin edges, and further enables the water bag 11 to form a plano-convex lens structure capable of concentrating light.

[0050] It can be known that the plano-convex lens formed by the water bag 11 concentrates light in the middle of the wall panel sandwich layer 15. In order to enable the light in this part to evenly pass through the inner curtain wall glass 3, the inner curtain wall glass 3 is set as a plano-concave lens. That is to say, the water bag 11 at the outer curtain wall glass 9 is used for concentrating light, and the plano-concave lens structure of the inner curtain wall glass 3 is used for diffusing light. Further, the function of the water bag 11 concentrating light will not affect the requirement of the entire curtain wall to evenly supply light to the room, and no light concentration point will be formed indoors, making the indoor light more uniform and soft.

[0051] Specifically, the linear driving member 2 here can be Figure 1 the electric push rod shown in the figure. In some other embodiments, a spring and a combination of a reel with rotational power and a steel wire rope can also be used. At this time, the spring provides the power for the moving seat 1 to move towards the outer curtain wall glass 9, the reel rotates to wind or unwind the steel wire rope, and the steel wire rope provides the power for the moving seat 1 to move away from the outer curtain wall glass 9. The specific connection method and other structural forms of the linear driving member 2 can be set by those skilled in the art themselves and will not be elaborated here.

[0052] In this embodiment, one side of the water bag 11 is attached to and fixed to the outer curtain wall glass 9. A plurality of elastic limiting columns 1003 are fixed on the side wall of the rod sleeve 1002 of the telescopic rod 10. The side surface of the water bag 11 facing the sandwich layer 15 has a plurality of concave limiting grooves, and the limiting columns 1003 are embedded in the limiting grooves.

[0053] Specifically, during the deformation of the water bag 11, the limiting columns 1003 are always inserted into the limiting grooves to realize the limitation of the connection position between the water bag 11 and the telescopic rod 10. In this setting method, the water bag 11 and the rod sleeve 1002 are connected by multiple points, which is convenient for making the expansion or contraction deformation of the water bag 11 in the limiting space 16 more uniform, and further making the deformation of the water bag 11 more conform to the space with a thick middle and thin edges defined by the limiting space 16.

[0054] Here, the water bladder 11 and the external curtain wall glass 9 can be adhesively fixed at multiple points through an adhesive. The adhesive is preferably arranged at the edge positions around the water bladder 11 close to the frame 5 to reduce the influence of the adhesive on the light transmission of the water bladder 11. The adhesive here can be made of materials such as epoxy resin or latex, which can be set by those skilled in the art and will not be elaborated here. In some other embodiments, a snap structure (not shown in the figure) can be provided at the four corners of the frame 5, and the edge of the water bladder 11 is arranged to be snapped into the snap, thereby realizing the limitation between the water bladder 11, the frame 5, and the external curtain wall glass 9. The snap structure can be set by those skilled in the art and will not be elaborated here.

[0055] More specifically, the telescopic rod 10 here includes a rod sleeve 1002 and an inner rod 1001. The end of the rod sleeve 1002 is hinged to the moving seat 1, and one end of the inner rod 1001 is embedded in the rod sleeve 1002, and the other end is hinged to the inner wall surface of the frame 5. The cross-sections of the telescopic rod 10 and the inner rod 1001 here are circular. In some other embodiments, the cross-sections of the two can also be other shapes such as oval or square, which can be set by those skilled in the art. Correspondingly, the cross-sections of the limiting post 1003 and the limiting groove here can also be circular or square, which can be set by those skilled in the art.

[0056] The limiting groove here is formed by the inward depression of the side wall of the water bladder 11. That is to say, the limiting groove and the inner cavity of the water bladder 11 are separated by the side wall of the water bladder 11, and the two are not connected. The above-mentioned limiting post 1003 is made of an elastic material. When the moving seat 1 moves towards the external curtain wall glass 9, the distance between the telescopic rod 10 and the external curtain wall glass 9 becomes smaller. When the telescopic rod 10 is approximately in a vertical state, the limiting post 1003 is compressed between the rod sleeve 1002 and the external curtain wall glass 9.

[0057] In this embodiment, brackets 12 are respectively installed around the inner wall of the frame 5. One end of the telescopic rod 10 is hinged to the bracket 12, and the telescopic rod 10 is an elastic rod. The outer contour of the moving seat 1 is cylindrical, and a plurality of installation grooves are evenly arranged on the outer circumferential surface of the moving seat 1. The other end of the telescopic rod 10 is hinged in the installation groove.

[0058] Specifically, the above-mentioned bracket 12 is arranged at one end of the frame 5 close to the external curtain wall glass 9 along the thickness direction of the wall panel (i.e., Figure 1 the right end shown). This setting method makes the convexity of the water bladder 11 become smaller when the bracket 12 approaches the external curtain wall glass 9, and the convexity of the water bladder 11 will become larger when the bracket 12 moves away from the external curtain wall glass 9. More specifically, the bracket 12 and the end of the inner rod 1001 can be hinged through a pin shaft (not shown in the figure) with the bracket 12. Correspondingly, the rod sleeve 1002 of the telescopic rod 10 is also hinged to the moving seat 1 through a pin shaft, and the other end of the rod sleeve 1002 is inserted into the installation groove.

[0059] In this embodiment, the moving seat 1 includes an elastic part and a rigid part which are fixedly connected. The rigid part is hinged to the telescopic rod 10. The elastic part is on the side close to the water bag 11 to abut against the water bag 11.

[0060] Specifically, the rigid part here can be a disc-shaped plate made of plastic or metal, and the elastic part is a disc-shaped plate made of silicone or rubber. The two are fixed by bolts or bonding. When the moving seat 1 is composed of an elastic part and a rigid part, the rigid part can provide a basis for the hinge of the telescopic rod 10, and the elastic part can contact the water bag 11. By the deformation of the elastic part, the probability that the water bag 11 is punctured at the position where the deformation is the largest and thinnest can be reduced.

[0061] In this embodiment, the water bag 11 is communicated with an indoor water tank (not shown in the figure). The indoor water tank includes a cold water bin and a hot water bin. The cold water bin is communicated with a rainwater collection component (not shown in the figure) of the building. The water inlet of the water bag 11 is communicated with the cold water bin, and the water outlet of the water bag 11 is communicated with the hot water bin.

[0062] Specifically, water pumps are respectively arranged between the water inlet of the water bag 11 and the cold water bin, and between the water blowing port and the hot water bin. The cold water is driven by the water pump to be transported from the cold water bin to the water bag 11, so that the water bag 11 expands to the required degree. The light concentration effect of the water bag 11 on sunlight enables the power generation power of the photovoltaic panel 14 in the middle of the interlayer 15 to reach the set threshold. When the water temperature in the water bag 11 is too high due to long-term sunlight irradiation, the hot water can be transported to the hot water bin through the water outlet and the corresponding water pump for indoor use in the building. Then, the cold water can be transported to the water bag 11 again.

[0063] Embodiment 2

[0064] The structural settings of this embodiment are basically the same as those of Embodiment 1, except that a wall panel is provided in which the orientation of the photovoltaic panel 14 in the interlayer 15 can be adjusted and the photovoltaic panel 14 can be vertically stored.

[0065] As Figures 6 - 11 shown, in this embodiment, two columns of photovoltaic panels 14 are arranged vertically. Along the width direction of the wall panel, the two columns of photovoltaic panels 14 are respectively on both sides of the linear driving member 2. The upper end of the frame 5 has a receiving cavity 6, and a plurality of photovoltaic panels 14 can be vertically lifted and stacked and stored in the receiving cavity 6.

[0066] Specifically, referring to Figure 7 and two pulling holes 141 and two adjusting holes 142 are provided on the photovoltaic panel 14. The two pulling holes 141 are arranged at both ends of the photovoltaic panel 14 along the length direction, and the two adjusting holes 142 are arranged at both ends of the photovoltaic panel 14 along the length direction. The pulling holes 141 and the adjusting holes 142 are respectively at both ends of the photovoltaic panel 14 along the width direction.

[0067] To achieve the storage and orientation adjustment of the photovoltaic panel 14, the storage rope 71 and the angle adjustment rope 72 are used as the traction rope 7 here. Specifically, the storage rope 71 passes through the pulling hole 141, and the angle adjustment rope 72 passes through the adjustment hole 142. A first cushion plate 144 is arranged at the lower end of the lowermost photovoltaic panel 14, and the lower end of the storage rope 71 is connected to the first cushion plate 144. Second cushion plates 143 are respectively attached to the upper and lower sides of the adjustment hole 142 in each photovoltaic panel 14, and the angle adjustment holes 142 respectively pass through different second cushion plates 143 and are fixed to the second cushion plates 143.

[0068] When the storage rope 71 is pulled upward, the first cushion plate 144 sequentially lifts different photovoltaic panels 14 from bottom to top and stacks all the photovoltaic panels 14 in columns. When the angle adjustment rope 72 is pulled upward, the photovoltaic panel 14 rotates along the horizontal axis to synchronously adjust the orientations of multiple photovoltaic panels 14.

[0069] More specifically, to drive the storage rope 71 and the angle adjustment rope 72, a first motor (not shown in the figure) and a second motor (not shown in the figure) are respectively arranged at the upper end of the frame 5. A first winding drum and a second winding drum are respectively coaxially fixed on the first motor and the second motor. The first winding drum is used for winding and unwinding the storage rope 71, and the second winding drum is used for winding or unwinding the angle adjustment rope 72.

[0070] In this embodiment, an air inlet 13 is provided at the lower end of the frame 5, and an air outlet 8 is provided at the upper end. A spray hole that can be independently opened and closed is provided on the side of the water bag 11 facing the interlayer 15, and the spraying direction of the spray hole faces the photovoltaic panel 14.

[0071] When the air inlet 13 and the air outlet 8 are provided on the above-mentioned frame 5, an air flow can be formed in the interlayer 15 to facilitate the cooling of the wall panel in summer. However, during long-term use, the dust accumulated in the interlayer 15, especially on the photovoltaic panel 14, will affect the power generation efficiency of the photovoltaic panel 14. In this embodiment, the spray holes are provided on the water bag 11, and the water bag 11 and the spray holes can be used to spray water on different photovoltaic panels 14, which is beneficial to cleaning the dust on the photovoltaic panel 14. Specifically, valves are respectively provided at the air inlet and the air outlet to facilitate opening and closing the interlayer.

[0072] Specifically, a miniature shut-off valve is provided at the spray hole to facilitate opening and closing the spray hole.

[0073] In this embodiment, at least two columns of water holes are arranged vertically downward, and both ends of each photovoltaic panel 14 in the horizontal direction are respectively aligned with one of the spray holes. The photovoltaic panel 14 is a bent plate with a middle part higher than both sides, and the included angle between the two parts of the bent plate is 165° - 175°.

[0074] See Figure 7, the bent plate includes a first plate 1401 and a second plate 1402 in the shape of a flat plate. The first plate 1401 and the second plate 1402 can be arranged in a split structure, and the two are connected into a whole through other structural members. It can be known that when the bent plate is adopted for the photovoltaic panel 14, after the photovoltaic panel 14 is rotated upward by a set angle, the cleaning water sprayed from the water spray holes to both ends of the photovoltaic panel 14 will flow along the inclined direction to the middle of the photovoltaic panel 14, which is convenient for realizing the cleaning work of the entire photovoltaic panel 14.

[0075] In this embodiment, a fan is installed at the air inlet 13 and / or the air outlet 8, and each photovoltaic panel 14 can be rotated separately so that the light-receiving surface faces downward, facing the flow direction of the air flow.

[0076] Specifically, the fan at the air inlet 13 and / or the air outlet 8 can increase the air flow in the interlayer 15, and with the light-receiving surface of the photovoltaic panel 14 facing downward, the upward air flow can be utilized to quickly dry the photovoltaic panel 14, reducing the cleaning time of the photovoltaic panel 14.
