DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0022] Example
[0023] like Figure 1-4 As shown, a windproof and heat-insulating roller shutter for the top opening of a livestock and poultry house comprises a livestock and poultry house side wall 1, one side of the livestock and poultry house side wall 1 is fixedly connected to a motor 2, the output end of the motor 2 is fixedly connected to a winding drum 3, one end of the winding drum 3 is fixedly connected to a universal telescopic joint 4, one end of the universal telescopic joint 4 is fixedly connected to a roller shutter body 5, the outer circumferential surface of the winding drum 3 is fixedly connected to and wound with a main steel wire rope 6, the outer circumferential surface of the main steel wire rope 6 is fixedly connected to a connecting piece 61, one end of the connecting piece 61 is fixedly connected to a branch steel wire rope 1 62 and a branch steel wire rope 2 63, one side of the livestock and poultry house side wall 1 is also fixedly connected to a main pulley 11, a sub-pulley 12, a sub-pulley 2 13, a pulley block 14 and a guide assembly 15, one end of the main steel wire rope 6 passes through the guide The assembly 15, the main pulley 11 and the branch pulley 12 are finally fixed to the upper end of the roller shutter body 5, the branch steel wire rope 1 62 is finally fixed to the upper end of the roller shutter body 5 through the branch pulley 2 13, and the branch steel wire rope 2 63 is finally fixed to the upper end of the roller shutter body 5 through the pulley group 14. The roller shutter body 5 includes an axle rod 51, a thermal insulation roller shutter 52, a connecting rod 53 and a counterweight rod 54. The axle rod 51 is fixedly connected to one end of the universal telescopic joint 4, and the outer circumferential surface of the axle rod 51 is fixedly connected to the thermal insulation roller shutter 52. The upper end of the thermal insulation roller shutter 52 is fixedly connected to the connecting rod 53. The connecting rod 53 is fixed to the main steel wire rope 6, the branch steel wire rope 1 62 and the branch steel wire rope 2 63, and the lower end of the thermal insulation roller shutter 52 is fixedly connected to the counterweight rod 54.
[0024] When in use, after turning on the motor 2, the motor 2 cooperates with the universal telescopic joint 4 to drive the roller shutter body 5 to be reeled in or extended. At the same time, the motor 2 also cooperates with the winding drum 3 to pay out or reel in the main steel wire rope 6. During the paying out process, the main steel wire rope 6 cooperates with the branch steel wire rope 1 62 and the branch steel wire rope 2 63 to lower the roller shutter body 5 in the reeled state, thereby realizing the top opening of the roller shutter body 5. During the reeling process, the main steel wire rope 6 cooperates with the branch steel wire rope 1 62 and the branch steel wire rope 2 63 to lift the extended roller shutter body 5, thereby realizing The shutter body 5 is now closed, and the shutter body 5 can be opened from the top by a single motor 2 for a large window without dividing the window, which greatly saves equipment costs. Driven by the motor 2 and the universal telescopic joint 4, the shaft rod 51 reels the thermal insulation shutter 52, specifically performing bidirectional rewinding. Since the thermal insulation shutter 52 is lowered while being rolled up during the rewinding process, even if it is rolled up in both directions, it can be ensured that the thermal insulation shutter 52 will only be opened from the top. However, bidirectional rewinding can greatly reduce the number of turns driven by the motor 2, thereby saving energy consumption and further saving costs.
[0025] like Figure 2 As shown, the pulley block 14 includes a branch pulley 3 141 and a branch pulley 4 142 , and the branch wire rope 2 63 is finally fixed to the upper end of the roller shutter body 5 through the branch pulley 3 141 and the branch pulley 4 142 .
[0026] Since the support wire rope 63 is close to the main pulley 11, if a sub-pulley is installed directly on the upper end of the roller shutter body 5, and the support wire rope 63 is to be in a taut state, the length of the wire rope 63 is not enough to lower the roller shutter body 5 into place. With the cooperation of the sub-pulley 3 141 and the sub-pulley 4 142, the installation length of the wire rope 63 can be increased, and the wire rope 63 can also be in a taut state, ensuring that the roller shutter body 5 can be lowered into place.
[0027] like Figure 3-4 As shown, the guide assembly 15 includes a guide roller 151 and a mounting frame 152 . Both ends of the guide roller 151 are rotatably connected to the mounting frame 152 , and the mounting frame 152 is fixedly connected to one side of the side wall 1 of the livestock and poultry house.
[0028] When in use, under the guidance of the guide roller 151, the main steel wire rope 6 can be brought closer to one side of the side wall 1 of the livestock house, and then the main steel wire rope 6 can remain horizontal and connected with the main pulley 11. If the guide roller 151 is not provided, the winding drum 3 and the main pulley 11 are misaligned, and the main steel wire rope 6 is directly connected with the main pulley 11, which will cause an angle between the main steel wire rope 6 and the main pulley 11, and further cause a large friction between the main steel wire rope 6 and the main pulley 11, affecting the service life of the main steel wire rope 6.
[0029] like Figure 3As shown, a pair of limit frames 16 are fixedly connected to one side of the side wall 1 of the livestock and poultry house, and the limit frames 16 are located on the outside of the roller shutter body 5.
[0030] When in use, the limiting frame 16 can limit the position of the rolling curtain body 5, and when a strong wind blows, the rolling curtain body 5 is not easy to be lifted.
[0031] In summary, the specific working process of this scheme is as follows: after the motor 2 is turned on, the motor 2 cooperates with the universal telescopic joint 4 to drive the roller shutter body 5 to be rolled up or extended. At the same time, the motor 2 also cooperates with the winding drum 3 to pay out or reel in the main steel wire rope 6. During the paying out process, the main steel wire rope 6 cooperates with the branch steel wire rope 1 62 and the branch steel wire rope 2 63 to lower the roller shutter body 5 in the rolled-up state, thereby realizing the top opening of the roller shutter body 5. During the reeling process, the main steel wire rope 6 cooperates with the branch steel wire rope 1 62 and the branch steel wire rope 2 63 to lift the extended roller shutter body 5, thereby realizing the closing of the roller shutter body 5, and then the roller shutter body 5 can be opened from the top by a single motor 2 for a large window without dividing the window, which greatly saves equipment costs.
[0032] Among them, under the drive of the motor 2 and the universal telescopic joint 4, the shaft rod 51 reels the thermal insulation roller curtain 52, specifically performing bidirectional rewinding. Since the thermal insulation roller curtain 52 is rolled up and lowered at the same time during the rewinding process, even if it is rolled up in both directions, it can be ensured that the thermal insulation roller curtain 52 will only be opened. However, bidirectional rewinding can greatly reduce the number of turns driven by the motor 2, thereby saving energy consumption and further saving costs.
[0033] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
