DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1-Figure 7 The utility model provides a technical solution: an electric shutter, comprising a rotating blade 1, the middle position of the left and right sides of which is rotatably connected to the window frame through a rotating shaft; a rotating component 2, which is arranged on the left and right sides of the front end of the rotating blade 1; the rotating component 2 comprises a rotating plate 201 and a moving rod 202, and the rotating plate 201 is rotatably connected to the front end of the rotating blade 1 through the rotating shaft, and the moving rod 202 is arranged through the middle position of the rotating plate 201; the rotating component 2 also includes a fastening screw 203, a limiting pad 204 and a fastening nut 205, and the fastening screw 203 is arranged at the lower end of the moving rod 202, and the limiting pad 204 is arranged through the outside of the fastening screw 203, and at the same time, the upper end of the limiting pad 204 is tightly fitted with the lower end of the rotating plate 201, and the fastening nut 205 is connected to the fastening screw 203 through a threaded hole opened in the middle position;

[0027] When the moving rod 202 needs to be disassembled (by disassembling the moving rod 202, the surface of the rotating blade 1 can be fully wiped and cleaned), turn the moving rod 202 to remove the moving rod 202. Figure 5The fastening nut 205 in the middle causes the fastening nut 205 to start moving in the direction away from the limiting pad 204 until the fastening nut 205 is no longer connected to the fastening screw 203. At this time, the fastening nut 205 can be removed, and then the limiting pad 204 can be pulled so that the limiting pad 204 is no longer in contact with the lowermost rotating plate 201. At this time, the moving rod 202 can be pulled upward (the moving rod 202 is connected to the rotating plate 201 through the through hole opened on the rotating plate 201, and the moving rod 202 is provided with a gasket made of soft rubber material, and the rubber gasket is respectively in contact with the upper and lower ends of the rotating blade 1, and the rotating blade 1 is set to be made of plastic material, that is, the weight of the rotating blade 1 is relatively light, and the gravity of the rotating blade 1 is not enough to deform the rotating blade 1). As the moving rod 202 is pulled upward with force, the rubber gasket provided on the moving rod 202 begins to be squeezed and deformed, and the rubber gasket begins to pass through the rotating plate The grooves on 201 are formed until the moving rod 202 is pulled and removed, so that the surface of the rotating blade 1 can be directly wiped or cleaned thoroughly, avoiding the situation that the left and right sides of the rotating blade 1 cannot be cleaned due to the obstruction of the moving rod 202, and by removing the moving rod 202, the rotating blades 1 are disconnected, that is, the rotating blades 1 are no longer connected to each other, so that when a certain rotating blade 1 is damaged, a single rotating blade 1 can be replaced (the rotating blade 1 is rotatably connected to the window frame through the rotating shaft, and the rotating shaft installed on the rotating blade 1 and the rotating blade 1 adopt a detachable structure, and the rotating blade 1 of some blinds is set to a deformable PVC material. Therefore, the rotating blade 1 that needs to be replaced can be directly pressed to deform the rotating blade 1, and the rotating blade 1 can be disassembled), and it is no longer necessary to replace the entire blade group, which can reduce the cost of replacement of damaged blades;

[0028] The double-axis motor 3 is arranged in the middle position of the upper surface of the window frame; the output shaft 4 is interconnected with the output end of the double-axis motor 3; the winding assembly 5 is arranged on the left and right sides of the window frame, and the winding assembly 5 is interconnected with the output shaft 4, and the winding assembly 5 is interconnected with the rotating assembly 2; the winding assembly 5 includes a winding wheel 504, a traction rope 505 and a positioning rope 506, and the traction rope 505 is installed at the upper end of the moving rod 202, and the positioning rope 506 is interconnected with the traction rope 505, and the traction rope 505 and the positioning rope 506 are arranged on the winding wheel 504; The winding assembly 5 also includes a fixed sleeve 501, a splicing screw 502 and a connecting plate 503, and the connecting plate 503 is installed on the winding wheel 504, the splicing screw 502 is connected to the connecting plate 503 through a threaded hole opened on the connecting plate 503, and the splicing screw 502 is set through the fixed sleeve 501, and the fixed sleeve 501 is connected to the output shaft 4; the traction rope 505 and the guide roller 6 are fitted with each other, and the outer surface of the guide roller 6 is set to be smooth, and the guide roller 6 is connected to the window frame in a rolling manner through a groove opened on the window frame;

[0029] When the aged traction rope 505 needs to be replaced, the lower end of the traction rope 505 is fixedly installed on the upper end of the moving rod 202 by gluing (adhesive fixation is performed by 3M super glue, etc.), the lower end of the traction rope 505 is pulled, and the traction rope 505 is separated from the upper end of the moving rod 202 by the blade, and then the splicing screw 502 is rotated to make the splicing screw 502 start to move away from the fixed sleeve 501 until the splicing screw 502 is no longer connected to the threaded hole opened on the connecting plate 503. At this time, the winding wheel 504 can be pulled so that the connecting plate 503 installed on the winding wheel 504 is no longer connected to the fixed sleeve 501. The inner surface fits, and the winding wheel 504 can be disassembled and removed. At this time, the traction rope 505 can be driven to be removed. After replacing the new winding wheel 504, the traction rope 505 set on the winding wheel 504 is passed through the through hole opened in the window frame, and then the traction rope 505 is glued to the upper end of the moving rod 202, and then the connecting plate 503 is moved in the direction close to the fixed sleeve 501, and the splicing screw 502 is rotated at this time to make the splicing screw 502 connect with the threaded hole opened in the connecting plate 503 again. At this time, the new winding wheel 504 can be fixed on the output shaft 4, so that the dual-axis motor 3 starts to work (the dual-axis motor 3 is connected to the rear end thereof by The wires are connected to the external control device, and the external control device is also connected to the indoor temperature sensor, humidity sensor and harmful gas sensor of the pig farm, so as to control the operation of the dual-axis motor 3 according to the indoor temperature and humidity of the pig farm, thereby controlling the opening and closing degree of the blinds), and the dual-axis motor 3 starts to work, that is, the dual-axis motor 3 starts to drive the output shaft 4 installed at its output end to start rotating (the left and right output ends of the dual-axis motor 3 can drive the mutually connected rotations to rotate synchronously in the same direction, which can ensure that the two winding wheels 504 are driven to rotate at the same time to avoid the situation of rotation time deviation), thereby driving the winding wheel 504 to rotate, that is As the winding wheel 504 rotates, the traction rope 505 begins to be wound. Under the action of the positioning rope 506, the traction rope 505 can be effectively prevented from sliding with the winding wheel 504 during the winding process, thereby effectively ensuring the winding effect of the traction rope 505. As the traction rope 505 is wound, the traction rope 505 begins to drive the moving rod 202 to move upward. At this time, the rotating plate 201 begins to rotate around the rotating blade 1, and the rotating blade 1 also begins to rotate around the window frame under the action of the rotating shafts set on the left and right sides, so that the opening and closing angles of the rotating blade 1 can be adjusted to ensure appropriate air flow and temperature in the pig farm room.
