DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1

[0021] See also Figures 1 to 6, which is the first embodiment of the present invention, and this embodiment provides a technical solution: a rotary shutter system for curtain wall, comprising a main frame 1 installed on the front surface of a curtain wall frame 4, a plurality of inclined blades 2 are rotatably installed on the inner side of the main frame 1, a driving structure 6 that can drive the inclined blades 2 is arranged on the left side of the main frame 1, the driving structure 6 includes a servo motor 61, a side cavity 62, a driving gear 63, a driving gear 64, a transmission toothed belt 65 and a driven gear 66, a drainage hole 11 is opened at the inner bottom end of the main frame 1, and also includes an intelligent monitoring opening and closing system, the intelligent monitoring opening and closing system includes an industrial control mainboard, a rainfall monitoring module, and a motor driving module , a blockage monitoring module and an alarm module. The rainfall monitoring module, the motor drive module, the blockage monitoring module and the alarm module are all connected to the industrial control mainboard. The motor drive module is connected to the servo motor 61. A plurality of rain sensors 8 are installed on the front surface of the main frame 1. The model of the rain sensor 8 is RS-GYL-X-1. The rainfall monitoring module is connected to the rain sensor 8. An infrared counter-beam sensor 9 is arranged at the bottom end of the main frame 1. The model of the infrared counter-beam sensor 9 is E3Z-T61. The blockage monitoring module is connected to the infrared counter-beam sensor 9. The infrared counter-beam sensor 9 includes infrared emitting terminals 91 respectively installed on the inner walls on both sides of the drainage hole 11 The left side surface of the main frame 1 is also equipped with an audible and visual alarm lamp 7, and the alarm module is connected to the audible and visual alarm lamp 7. When actually used, the rain sensor 8 will monitor the outdoor situation in real time. If it rains outside, it will be sensed by the rain sensor 8 in time. The rain sensor 8 transmits the signal to the rainfall monitoring module, and the rainfall monitoring module transmits the signal to the industrial control mainboard. At this time, the industrial control mainboard starts the motor drive module, and the motor drive module drives the servo motor 61 to rotate forward or flip according to the command issued by the industrial control mainboard, so as to achieve the purpose of automatically realizing the rotation and closing of the inclined blade 2 when it rains. At the same time, some raindrops in the rainfall process Rainwater on the inner side of the main frame 1 will be discharged through the drainage hole 11. If the drainage hole 11 is blocked during daily use, the blocked object will block the signal between the infrared transmitting end 91 and the infrared receiving end 92, thereby being sensed by the infrared counter-radiation sensor 9. The infrared counter-radiation sensor 9 transmits the signal to the blockage monitoring module, and the blockage monitoring module transmits the signal to the industrial control mainboard. The industrial control mainboard then starts the alarm module, and the alarm module lights up the sound and light alarm lamp 7 to remind the operator to clean the drainage hole 11 in time to prevent it from affecting the smooth drainage during subsequent rainfall, thereby avoiding the infiltration of external rainwater due to the blockage of the drainage hole 11.

[0022] The side cavity 62 is opened inside the left end of the main frame 1, and the upper and lower ends of the side cavity 62 are rotatably mounted with a driving gear 63 and a driven gear 66, respectively. The left end of the inclined blade 2 is fixed with a shaft 21, and the end of the shaft 21 passes through the side cavity 62 and is fixedly connected with a driving gear 64. The other side of the driving gear 64 is rotatably mounted on the inner wall of the side cavity 62 through a bearing. A transmission toothed belt 65 is connected between the driving gear 63 and the driven gear 66, and the inner surface of the transmission toothed belt 65 is meshed with the driving gear 64. The servo motor 61 is mounted on the left side surface of the main frame 1, and the servo motor 6 The output end of 1 passes through the inner side of the side cavity 62 and is connected to the driving gear 63. After the subsequent servo motor 61 is started, it will drive the driving gear 63 to rotate, and the driving gear 63 will drive the transmission toothed belt 65 to operate. Since the inner wall of the transmission toothed belt 65 is meshed with multiple driving gears 64, when the transmission toothed belt 65 rotates around the driving gear 63 and the driven gear 66, it will drive multiple driving gears 64 to rotate, and the driving gear 64 will rotate with the inclined blade 2 through the shaft 21 to realize the rotation and closure of the inclined blade 2. The right end of the inclined blade 2 is rotatably mounted on the inner wall of the main frame 1 through the rotating shaft.

[0023] Among them, the upper and lower surfaces of the main frame 1 are welded with fixed base blocks 3, and the front surface of the fixed base block 3 is provided with multiple bolt grooves 31, and fixing bolts 32 are embedded and installed in the bolt grooves 31. The fixed base block 3 is fixedly connected to the curtain wall frame 4 through the fixing bolts 32.

[0024] Example 2

[0025] See also Figures 1 to 7 , which is the second embodiment of the present invention, is based on the previous embodiment, but differs in that the protective structure 5 can be provided to effectively cover, block and protect the bolt groove 31 during use.

[0026] Specifically, a plurality of protective structures 5 corresponding to the bolt slots 31 are provided on the curtain wall frame 4. The protective structure 5 includes a circular rotating seat 51 which is rotatably installed on the front surface of the curtain wall frame 4 through a rotating shaft. A protective cover plate 52 is welded and fixed to the front end surface of the circular rotating seat 51. The end of the protective cover plate 52 extends to the front surface of the fixed base block 3 to cover the bolt slots 31. During use, the bolt slots 31 can be effectively covered and blocked to prevent accidental entry of foreign objects. At the same time, the protective cover plate 52 can also prevent the fixing bolts 32 from falling off and limiting them, thereby ensuring the installation stability of the entire shutter system.

[0027] The protective structure 5 further includes an inner groove 53, a spring 54, a hemispherical telescopic block 55 and a positioning groove 56. The inner groove 53 is provided in the circular rotating seat 51, and the hemispherical telescopic block 55 is movably installed in the inner groove 53 through the spring 54. The surface of the fixed base block 3 is provided with a plurality of positioning grooves 56 corresponding to the hemispherical telescopic block 55. One end of the hemispherical telescopic block 55 pops out to the outside of the circular rotating seat 51 and is inserted into the positioning groove 56, which can assist in limiting the circular rotating seat 51. The protective cover 52 can stably cover the bolt groove 31. If the fixed base block 3 and the curtain wall frame 4 are to be separated later, the protective cover 52 only needs to be pushed hard to rotate the circular rotating seat 51. When the circular rotating seat 51 rotates, the end of the hemispherical telescopic block 55 will be squeezed out of the positioning groove 56, so that the circular rotating seat 51 can rotate smoothly, thereby smoothly rotating the protective cover 52 away from the front surface of the fixed base block 3, and the fixing bolts 32 can be disassembled and screwed normally.
