Technical Field
[0001] This utility model relates to the technical field of sunshade curtains, specifically an environmentally friendly sunshade curtain for building construction. Background Technology
[0002] During construction, construction sites often face challenges such as high temperatures and intense sunlight, posing threats to the health and safety of workers and impacting construction efficiency and project quality. To address these issues, traditional shading methods such as shade nets and shade fabrics are widely used. However, these materials often lack self-cleaning capabilities, easily accumulating dust and reducing their shading effectiveness. Furthermore, they are difficult to recycle and dispose of after construction, thus burdening the environment. Utility Model Content
[0003] The present invention addresses the technical problem that traditional shading measures lack self-cleaning function and are difficult to recycle after construction, and provides an environmentally friendly shading curtain for building construction.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an environmentally friendly sunshade curtain for building construction, comprising a sunshade curtain shell, a winding mechanism, a sunshade curtain, two fixing mechanisms, a water spraying mechanism, a solar film, a storage battery, a controller, a switch wire, and a switch. The winding mechanism is located at the bottom of the sunshade curtain shell. The sunshade curtain is mounted on the winding mechanism, and the two fixing mechanisms are positioned opposite each other on both sides of the sunshade curtain shell. The water spraying mechanism is mounted on the sunshade curtain shell. The solar film is laid on the surface of the sunshade curtain and fixedly connected to it. The storage battery is located below the sunshade curtain shell and fixedly connected to the bottom surface of the sunshade curtain shell. The controller is located below the sunshade curtain shell and is electrically connected to the storage battery, the winding mechanism, and the water spraying mechanism. One end of the switch wire is located below the sunshade curtain shell and fixedly connected to the bottom surface of the sunshade curtain shell; the switch wire is electrically connected to the controller. The switch is located at the other end of the switch wire and is fixedly and electrically connected to the switch wire.
[0005] The solar film collects solar energy during the sunshade's deployment to charge the battery, ensuring its continuous operation. A switch, via a switch wire, enables the controller to operate the fixing mechanism and water spray mechanism.
[0006] Two fixing mechanisms are used to install the sunshade. When the sunshade needs to be installed, the construction workers face the solar film portion of the sunshade towards the sun. Then, the construction workers use the two fixing mechanisms to fix the sunshade to the top of the building structure in the area that needs shading, ensuring the stability and safety of the sunshade. Then the sunshade can be used for shading.
[0007] When construction workers need to use this sunshade curtain for sun protection, they can control the rolling mechanism through a switch to make the sunshade curtain unfold smoothly from the rolling mechanism and cover the designated sun-shading area, providing the necessary shaded environment for the construction workers.
[0008] During the unfolding process, as dust accumulates on the surface of the sunshade, workers control a water spray system to spray water onto the top of the sunshade. The water, under gravity, carries the dust from the top to the bottom of the sunshade, effectively washing and cleaning the entire surface. The slow evaporation of the moisture on the sunshade surface under the sun's high temperature also provides additional cooling for the sunshade and its surrounding environment, improving the comfort and sustainability of the work environment.
[0009] Furthermore, the winding mechanism includes a mounting groove, a winding shaft, and a winding motor. The mounting groove is located on the bottom surface of the sunshade housing and communicates with the interior of the sunshade housing. The winding shaft is horizontally positioned inside the mounting groove, with both ends of the winding shaft rotatably connected to the inner side of the mounting groove via bearings. The surface of the winding shaft is fixedly connected to one end of the sunshade. The winding motor is located on the side of the sunshade housing, with its shaft axis coinciding with the axis of the winding shaft. The shaft of the winding motor passes through the side wall of the sunshade housing and enters the interior of the mounting groove, where it is fixedly connected to one end of the winding shaft. The side of the winding motor is fixedly connected to the side of the sunshade housing, and the winding motor is electrically connected to the controller.
[0010] When the sunshade needs to be unfolded or rolled up, the construction worker presses the switch to send a command to the controller to unfold or roll up the sunshade. After receiving the command from the switch via the switch line, the controller controls the forward and reverse rotation of the winding motor shaft to make the winding shaft rotate in both directions, thereby unfolding or rolling up the sunshade.
[0011] Furthermore, the fixing mechanism includes a fixing plate and screw holes. The fixing plate is inverted "L" shape and is located on the side of the sunshade curtain housing, above the winding shaft. The top surface of the fixing plate is flush with the top surface of the sunshade curtain housing, and the fixing plate is fixedly connected to the side of the sunshade curtain housing. The screw holes are located on the top surface of the fixing plate and are continuous from top to bottom.
[0012] When installing this sunshade curtain for sun shading, the construction workers can find the screws that match the screw holes and screw them into the top of the building structure in the area that needs sun shading to ensure the stability and safety of the sunshade curtain, and then the sunshade curtain can be used for sun shading.
[0013] Furthermore, it includes a hanging ring, which is disposed on the side of the inner side of the fixing plate and is fixedly connected to the inner side of the fixing plate.
[0014] When the building structure in the area requiring shade cannot be installed on top of the shade curtain, construction workers can find suitable ropes, tie one end of the rope to the hanging ring, tie the other end to the nearby building structure, and pull it straight and taut to ensure that the shade curtain shell is horizontal and not tilted. Then the shade curtain can be used for shading.
[0015] Furthermore, the water spray mechanism includes a water storage box, a water box inlet, a sealing cap, a small water pump, two strip-shaped nozzles, a water supply pipe, a main water supply pipe, and two branch water supply pipes. The water storage box is located on the side of the sunshade curtain housing parallel to the winding shaft, and is fixedly connected to the side of the sunshade curtain housing. The water box inlet is located on the top surface of the water storage box and communicates with the interior of the water storage box. The sealing cap is located on the water box inlet and is threadedly connected to the water box inlet. The small water pump is located on the side of the sunshade curtain housing away from the winding motor, below the fixing plate, and is fixedly connected to the side of the sunshade curtain housing. The small water pump is electrically connected to the controller. The two strip-shaped nozzles are arranged opposite each other and laterally below the sunshade curtain housing, parallel to the winding shaft. The two strip-shaped nozzles are located on both sides of the mounting groove and are fixedly connected to the bottom surface of the sunshade curtain housing. One end of the water supply pipe is located on the side of the water storage box, and the other end is located on the side of the small water pump inlet. One end of the water supply pipe is fixedly connected to the side of the water storage box and communicates with the inside of the water storage box, while the other end is fixedly connected to and communicates with the small water pump inlet. One end of the main water supply pipe is located on the side of the small water pump outlet, and the other end of the main water supply pipe is fixedly connected to and communicates with the outlet of the small water pump. One end of each of the two water supply sub-pipes is located on either side of the other end of the main water supply pipe, and the other end is located on the side of the inlet of each of the two strip-shaped sprinkler heads. One end of each of the two water supply sub-pipes is fixedly connected to and communicates with the other end of the main water supply pipe, and the other end is fixedly connected to and communicates with the inlet of each of the two strip-shaped sprinkler heads.
[0016] During the unfolding process, when dust accumulates on the surface of the sunshade curtain, the construction workers activate a small water pump via a switch. Once activated, the pump draws water from the storage tank through the supply pipe and pressurizes it. The pressurized water is then distributed through the main supply pipe to two sub-pipes, which in turn deliver it to two strip-shaped nozzles. The nozzles, with their internal structure diverting the water flow, spray water onto the top surface of the sunshade curtain. The water, under the influence of gravity, carries the dust from the top of the curtain to its base, effectively cleaning the entire curtain. Furthermore, the slow evaporation of the moisture from the curtain's surface under the sun's high temperature provides additional cooling for the curtain and its surrounding environment, improving the comfort and sustainability of the construction environment.
[0017] When the water tank is empty, construction workers can unscrew the sealing cap and add water to the tank through the opening.
[0018] Furthermore, the solar thin film is a CIGS solar thin film.
[0019] CIGS solar thin films have high photoelectric conversion efficiency, effectively converting sunlight into electrical energy. These films are lightweight and flexible, allowing for easy installation on the surface of sunshades.
[0020] The beneficial effects of this utility model are: the sunshade curtain uses solar thin film to charge the battery with solar energy, which reduces the dependence on traditional energy and reduces carbon emissions.
[0021] The strip-shaped nozzles effectively clean the surface of the sunshade curtain, reducing the need for manual cleaning and improving ease of use.
[0022] This sunshade can be quickly installed and adjusted using screw holes and hanging rings, and can be rapidly deployed and retrieved in a variety of construction environments, demonstrating high adaptability and flexibility. Attached Figure Description

[0026] To make this utility model easier to understand, the following detailed description of the utility model concept and its technical effects will be provided to fully illustrate the purpose, features and effects of this utility model.
[0027] like Figure 1-2This invention illustrates an environmentally friendly sunshade curtain for building construction, comprising a sunshade curtain shell 1, a winding mechanism, a sunshade curtain 2, two fixing mechanisms, a water spray mechanism, a solar film 3, a battery 4, a controller 5, a switch wire 6, and a switch 7. The winding mechanism is located at the bottom of the sunshade curtain shell 1. The sunshade curtain 2 is mounted on the winding mechanism, and the two fixing mechanisms are positioned opposite each other on both sides of the sunshade curtain shell 1. The water spray mechanism is mounted on the sunshade curtain shell 1. The solar film 3 is laid on the surface of the sunshade curtain 2 and is fixedly connected to it. The battery 4 is located below the sunshade curtain shell 1 and is fixedly connected to the bottom surface of the sunshade curtain shell 1. The controller 5 is located below the sunshade curtain shell 1 and is electrically connected to the battery 4, the winding mechanism, and the water spray mechanism. One end of the switch wire 6 is located below the sunshade curtain shell 1 and is fixedly connected to the bottom surface of the sunshade curtain shell 1; the switch wire 6 is also electrically connected to the controller 5. Switch 7 is located at the other end of switch line 6. Switch 7 is fixedly connected to switch line 6 and electrically connected to it.
[0028] The solar film 3 collects solar energy during the deployment of the sunshade 2 to charge the battery 4, ensuring the continuous operation of the sunshade. The switch 7 enables the controller 5 to control the opening and operation of the fixing mechanism and the water spray mechanism via the switch line 6.
[0029] Two fixing mechanisms are used to install the sunshade. When the sunshade needs to be installed for sun shading, the construction workers face the solar film 3 on the sunshade 2 towards the sun. Then, the construction workers use the two fixing mechanisms to fix the sunshade to the top of the building structure in the area that needs sun shading, ensuring the stability and safety of the sunshade. Then the sunshade can be used for sun shading.
[0030] When construction workers need to use this sunshade curtain for sun protection, they can control the rolling mechanism through switch 7 to make the sunshade curtain 2 smoothly unfold from the rolling mechanism and cover the designated sunshade area, providing the necessary shaded environment for the construction workers.
[0031] During the unfolding process, when dust accumulates on the surface of the sunshade curtain 2, the construction worker controls the water spray mechanism via switch 7. This mechanism sprays water onto the top of the sunshade curtain 2, and the water, under the influence of gravity, carries the dust from the top to the bottom of the curtain, thus cleaning the entire curtain. The moisture on the surface of the sunshade curtain 2 slowly evaporates under the high temperature of the sun, providing additional cooling for the curtain and its surrounding environment. This improves the comfort and sustainability of the construction environment.
[0032] The winding mechanism includes a mounting groove 8, a winding shaft 9, and a winding motor 10. The mounting groove 8 is located on the bottom surface of the sunshade housing 1 and communicates with the interior of the sunshade housing 1. The winding shaft 9 is horizontally positioned inside the mounting groove 8, and its two ends are rotatably connected to the inner side of the mounting groove 8 via bearings. The surface of the winding shaft 9 is fixedly connected to one end of the sunshade 2. The winding motor 10 is located on the side of the sunshade housing 1, and the axis of rotation of the winding motor 10 coincides with the axis of rotation of the winding shaft 9. The axis of rotation of the winding motor 10 passes through the side wall of the sunshade housing 1 and enters the interior of the mounting groove 8, where it is fixedly connected to one end of the winding shaft 9. The side of the winding motor 10 is fixedly connected to the side of the sunshade housing 1, and the winding motor 10 is electrically connected to the controller 5.
[0033] When it is necessary to unfold or roll up the sunshade curtain 2, the construction personnel press the switch 7 to send the command to the controller 5 to unfold or roll up the sunshade curtain 2. After receiving the command sent by the switch 7 through the switch line 6, the controller 5 controls the forward and reverse rotation of the rotating shaft of the winding motor 10 to make the winding shaft 9 rotate forward and reverse, thereby realizing the unfolding or rolling up of the sunshade curtain 2.
[0034] The fixing mechanism includes a fixing plate 11 and screw holes 12. The fixing plate 11 is inverted "L" shape and is located on the side of the sunshade housing 1, above the winding shaft 9. The top surface of the fixing plate 11 is flush with the top surface of the sunshade housing 1, and the fixing plate 11 is fixedly connected to the side of the sunshade housing 1. The screw holes 12 are located on the top surface of the fixing plate 11 and are continuous from top to bottom.
[0035] When installing the sunshade curtain for sun shading, the construction workers can find the screw that matches the screw hole 12, screw it into the top of the building structure in the area that needs sun shading through the screw hole 12, and ensure the stability and safety of the sunshade curtain, then the sunshade curtain can be used for sun shading.
[0036] Includes a hanging ring 13, which is disposed on the side of the inner side of the fixing plate 11 and is fixedly connected to the inner side of the fixing plate 11.
[0037] When the building structure in the area requiring shade cannot be installed on top of the shaded area, construction workers can find suitable ropes, tie one end of the rope to the hanging ring 13, tie the other end to the nearby building structure, and pull it straight and taut so that the shaded curtain shell 1 is horizontal and not tilted, then the shaded curtain can be used for shading.
[0038] The water spray mechanism includes a water storage box 14, a water box inlet, a sealing cover 15, a small water pump 16, two strip-shaped nozzles 17, a water supply pipe 18, a main water supply pipe 19, and two branch water supply pipes 20. The water storage box 14 is located on the side of the sunshade curtain housing 1 parallel to the side of the winding shaft 9, and is fixedly connected to the side of the sunshade curtain housing 1. The water box inlet is located on the top surface of the water storage box 14 and communicates with the interior of the water storage box 14. The sealing cover 15 is located on the water box inlet and is threadedly connected to the water box inlet. The small water pump 16 is located on the side of the sunshade curtain housing 1 away from the winding motor 10, below the fixing plate 11, and is fixedly connected to the side of the sunshade curtain housing 1. The small water pump 16 is electrically connected to the controller 5. Two strip-shaped nozzles 17 are arranged opposite each other and laterally below the sunshade housing 1, parallel to the winding shaft 9. The two nozzles 17 are located on either side of the mounting groove 8 and are fixedly connected to the bottom surface of the sunshade housing 1. One end of the water supply pipe 18 is located on the side of the water storage box 14, and the other end is located on the side of the inlet of the small water pump 16. One end of the water supply pipe 18 is fixedly connected to the side of the water storage box 14 and communicates with the interior of the water storage box 14, while the other end is fixedly connected to and communicates with the inlet of the small water pump 16. One end of the main water supply pipe 19 is located on the side of the outlet of the small water pump 16, and one end of the main water supply pipe 19 is fixedly connected to and communicates with the outlet of the small water pump 16. One end of each of the two water supply pipes 20 is located on both sides of the other end of the main water supply pipe 19, and the other end is located on the side of the inlet of each of the two strip nozzles 17. One end of each of the two water supply pipes 20 is fixedly connected to and communicates with the other end of the main water supply pipe 19, and the other end is fixedly connected to and communicates with the inlet of each of the two strip nozzles 17.
[0039] During the unfolding process of the sunshade curtain 2, when dust accumulates on its surface, the construction personnel start the small water pump 16 via switch 7. After starting, the small water pump 16 draws water from the water storage box 14 through the water supply pipe 18 and pressurizes it. The pressurized water is then diverted through the main water supply pipe 19 into two water supply branches 20, and from there delivered to two strip-shaped nozzles 17. Under the diversion effect of the internal structure of the two strip-shaped nozzles 17, water is sprayed onto the top surface of the sunshade curtain 2. The sprayed water, under the action of gravity, carries the dust from the surface of the sunshade curtain 2 from the top to the bottom, completing the rinsing of the entire sunshade curtain 2 and achieving cleaning. The slow evaporation of the moisture on the surface of the sunshade curtain 2 under the high temperature of the sun also provides an additional cooling effect for the sunshade curtain and its surrounding environment, improving the comfort and sustainability of the construction environment.
[0040] When there is no water inside the water storage box 14, the construction workers can unscrew the sealing cap 15 and add water into the water storage box 14 through the water box opening.
[0041] Solar film 3 is a CIGS solar film.
[0042] CIGS solar thin films have high photoelectric conversion efficiency, effectively converting sunlight into electrical energy. These films are lightweight and flexible, allowing for easy installation on the surface of the sunshade 2.
[0043] The working principle of this utility model is as follows:
[0044] When installing the sunshade curtain for sun shading, the construction workers can find the screw that matches the screw hole 12 and screw it into the top of the building structure in the area that needs sun shading to ensure the stability and safety of the sunshade curtain.
[0045] When the building structure in the area requiring shade cannot be installed on top of the shaded area, construction workers can find suitable ropes, tie one end of the rope to the hanging ring 13, tie the other end to the nearby building structure, and pull it straight and taut so that the shaded curtain shell 1 is horizontal and not tilted, then the shaded curtain can be used for shading.
[0046] When it is necessary to unfold or roll up the sunshade curtain 2, the construction personnel press the switch 7 to send the command to the controller 5 to unfold or roll up the sunshade curtain 2. After receiving the command sent by the switch 7 through the switch line 6, the controller 5 controls the forward and reverse rotation of the rotating shaft of the winding motor 10 to make the winding shaft 9 rotate forward and reverse, thereby realizing the unfolding or rolling up of the sunshade curtain 2.
[0047] During the unfolding process of the sunshade curtain 2, when dust accumulates on its surface, the construction personnel start the small water pump 16 via switch 7. After starting, the small water pump 16 draws water from the water storage box 14 through the water supply pipe 18 and pressurizes it. The pressurized water is then diverted through the main water supply pipe 19 into two water supply branches 20, and from there delivered to two strip-shaped nozzles 17. Under the diversion effect of the internal structure of the two strip-shaped nozzles 17, water is sprayed onto the top surface of the sunshade curtain 2. The sprayed water, under the action of gravity, carries the dust from the surface of the sunshade curtain 2 from the top to the bottom, completing the rinsing of the entire sunshade curtain 2 and achieving cleaning.
