Description

Technical Field

[0001] The utility model relates to the technical field of sunshade devices, in particular to a solar sunshade device. Background Art

[0002] Building sunshade devices are mainly aimed at light-transmitting surfaces such as large building windows. When the sun intensity is too high, the sunshade devices are used to block the light-transmitting surfaces such as building windows to prevent direct sunlight, thereby avoiding problems such as too high indoor temperature and overheated environment, and at the same time avoiding potential safety hazards such as fires caused by direct sunlight entering the room. Chinese patent document CN220798197U discloses a solar sunshade panel for photovoltaic buildings, which includes a fixed outer frame, a bracket, a chute, a cleaning roller, a drain port, a solar panel, etc. It improves the defect that the current solar sunshade panel does not have automatic cleaning, enables the sunshade panel to be automatically cleaned after rain or sandstorm weather, reduces the complexity of manual cleaning, and improves the use condition of the sunshade panel. However, during the opening process of the solar sunshade panel, a certain angle will be formed between the bracket and the fixed outer frame (see the attached drawings in the specification of this patent document Figure 1 ), and the outer surface of the building needs to provide a certain use space for it, which greatly limits the use range of the solar sunshade panel and has certain limitations; at the same time, after the fixed outer frame and the bracket of the solar sunshade panel are closed, the ventilation is poor, which easily leads to a closed high-temperature environment indoors and affects the comfort of the room. Summary of the Utility Model

[0004] The purpose of the utility model is achieved by the following technical solutions:

[0005] A solar sunshade device includes a fixed cross beam, connecting support rods, a fixed base and a solar cell module. The bottom surfaces of both ends of the fixed cross beam are respectively connected to the top surfaces of both ends of the fixed base through the connecting support rods. The two connecting support rods are parallel to each other, and the fixed cross beam is parallel to the fixed base; a roller mechanism is arranged inside the fixed cross beam.

[0021] A roller mechanism is arranged inside the fixed crossbeam 10. The roller mechanism includes a rotating shaft 11, a roller 12 and a sunshade cloth 13. The roller 12 is fixedly sleeved on the outer wall of the rotating shaft 11 and the roller 12 is collinear with the central axis of the rotating shaft 11. Both ends of the rotating shaft 11 are respectively rotatably connected to the inner side walls of the fixed crossbeam 10. At the same time, planar scroll springs are respectively arranged at both ends of the rotating shaft 11 (the planar scroll springs can be common planar scroll springs in the art, and no specific limitation is made in this embodiment, and the setting of the planar scroll springs is also an existing conventional means). The sunshade cloth 13 is coated on the outer wall of the roller 12 (the sunshade cloth 13 can be a commonly used cloth with good light-shielding property in the art, and no specific limitation is made in this embodiment); A slide bar 23 is arranged between the two connecting support rods 20 and the slide bar 23 is respectively slidably connected to the connecting support rods 20. The slide bar 23 is controlled to slide on the connecting support rods 20 through a lead screw 22 arranged in the connecting support rods 20; Specifically: a chute 21 is opened in the connecting support rod 20 and a rotating lead screw 22 is arranged in the chute 21 (that is, the upper and lower ends of the lead screw 22 are respectively rotatably connected to the side walls of the chute 21, refer to Figure 2 as shown), the slide bar 23 is respectively provided with sliding blocks 230 corresponding to the chute 21 and the sliding blocks 230 are slidably clamped in the corresponding chute 21 (such as Figure 2 as shown), the sliding blocks 230 are penetrated by the lead screw 22 in the corresponding chute 21 and are threadedly connected. The slide bar 23 is parallel to the fixed crossbeam 10 and the side surface of the slide bar 23 close to the fixed crossbeam 10 is fixedly connected to one end of the sunshade cloth 13 away from the roller 12 (a linear groove is opened on the bottom surface of the fixed crossbeam 10 corresponding to the sunshade cloth 13 for the sunshade cloth 13 to extend out and be connected to the slide bar 23). The rotation of the lead screw 22 is controlled by a driving mechanism arranged in the fixed base 30; Specifically: the driving mechanism includes a driving shaft 31, a first bevel gear 32 and a second bevel gear 220. The driving shaft 31 is rotatably arranged in the inner cavity of the fixed base 30 (refer to Figure 3 as shown, both ends of the driving shaft 31 are respectively rotatably connected to the side walls of the inner cavity of the fixed base 30) and the first bevel gears 32 are respectively fixedly sleeved on the outer walls of both ends of the driving shaft 31 corresponding to the lead screw 22. The bottom end of the lead screw 22 penetrates through the bottom surface of the corresponding connecting support rod 20 and the top surface of the fixed base 30 and the outer wall of the lead screw 22 located in the inner cavity of the fixed base 30 is fixedly sleeved with the second bevel gear 220, and the second bevel gear 220 meshes with the corresponding first bevel gear 32.

[0022] The solar cell module 40 is arranged on the upper side of the fixed cross beam 10 (i.e., the side surface far from the connecting support rod 20); the solar cell module 40 can use common solar cells in the art, and only needs to meet the function of converting solar energy into electrical energy and supplying power to the motor. In this embodiment, no specific limitation is made, and those skilled in the art can understand. The drive shaft 31 is driven to rotate by a motor arranged in the fixed base 30 (the connection mode of the motor driving the rotating shaft 31 can adopt the conventional design in the art, such as connecting the motor and the drive shaft 31 through a gear pair, etc. In this embodiment, no excessive limitation is made), and the motor is electrically connected to the solar cell module 40.

[0023] A transparent shielding shed 41 is arranged on the end face of the fixed cross beam 10 (as shown in combination Figure 1 with Figure 2 ), which is used to shield the solar cell module 40 and prevent rain erosion.

[0024] Working principle:

[0025] During use, the bracket composed of the fixed cross beam 10, the connecting support rod 20, and the fixed base 30 is installed on the outer circle of the light-transmitting surface of the building exterior wall (such as a window, etc.) through expansion screws, bolts, etc. (the expansion screws, bolts, etc. can adopt the conventional models in the art, and only need to meet the purpose of firmly connecting the bracket composed of the fixed cross beam 10, the connecting support rod 20, and the fixed base 30 with the building exterior wall, and those skilled in the art can understand). The solar cell module 40 is fixedly installed on the end face of the fixed cross beam 10 through a positioning bracket and screws, etc., and a transparent shielding shed 41 is arranged on the end face of the fixed cross beam 10 outside the solar cell module 40 (the shielding shed 41 can be made of glass or transparent plastic, etc.). When the external sunlight intensity is too high (the external light intensity can be detected by a light sensor arranged on the fixed cross beam 10, and the light sensor can adopt the common models in the art), the solar cell module 40 supplies power to the motor and starts the motor to operate. The motor drives the drive shaft 31 to rotate, and then realizes the simultaneous and reverse rotation of the two lead screws 22. The thread directions of the two lead screws 22 are set to be opposite. During the reverse rotation of the two lead screws 22, the slide rod 23 is simultaneously driven to move from the fixed cross beam 10 towards the fixed base 30, thereby pulling the sunshade cloth 13 to shield the corresponding light-transmitting surface of the building exterior wall. At this time, the rotating shaft 11 rotates and the flat spiral spring is compressed, thereby realizing the flat shielding of the sunshade cloth 13, and being able to provide buffering for the movement and ensure the air permeability in the room, avoiding the formation of a sealed high-temperature environment in the room.

[0026] Embodiment 2:

[0027] As a further optimization of the solution of the present utility model, on the basis of the solution of Embodiment 1, in order to achieve real-time cleaning of the sunshade cloth 13 and avoid dust accumulation thereon, a cleaning scraper is detachably arranged between the two connecting support rods 20 and located between the fixed cross beam 10 and the sliding rod 23. The cleaning scraper is in contact with the surface of the end of the sunshade cloth 13 that exposes the fixed cross beam 10, so as to achieve real-time cleaning of the sunshade cloth 13 when the sunshade cloth 13 extends or retracts.

[0028] In addition, a cleaning brush can also be arranged at the notch of the linear groove for cleaning the sunshade cloth 13.
