[0021] Specifically, please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall structure of a roller curtain device for heat preservation of dairy cows in efficient breeding provided by an embodiment of the present application. Figure 2 This is a schematic diagram of a partial cross-sectional structure of a rolling curtain in a retracted state provided by an embodiment of the present application. Figure 3 This is a schematic diagram of a partial cross-sectional structure of a rolling curtain in a down state provided by an embodiment of the present application. Figure 4A schematic diagram of the local structure of the ventilation window provided in the embodiment of the present application. The roller shutter device 100 for heat preservation of dairy cows for efficient breeding includes a cowshed 110, and the cowshed 110 includes a wall body 111 and a roof 112. The cowshed 110 here is the prior art. The roof 112 of the cowshed 110 is usually a herringbone roof 112. A plurality of ventilation windows 113 are arranged on the wall body 111. The ventilation windows 113 are used to open in time for ventilation when the temperature is high, and to close in winter when the temperature is low, so as to maintain the stability of the temperature inside the cowshed 110. The roof 112 is a herringbone shape, and the roof 112 includes a plurality of inclined purlins 114. The purlins 114 are the existing structure of the roof 112. The purlins 114 are overlapped on the beams to maintain the stability of the roof 112. The purlins 114 correspond to the air windows 113 respectively. When designing the air windows 113, the position of the air windows 113 can be selected according to the position of the purlins 114. Specifically, the air windows 113 can be opened below the two purlins 114. The arrangement of the purlins 114 and the air windows 113 respectively corresponding to each other facilitates the subsequent installation of components such as the rolling curtain 141. A first slide 120 is fixed on the inner side wall of the air window 113, and a second slide 130 is commonly fixed between two adjacent purlins 114. A rotating shielding component 140 connected end to end is commonly sleeved between the first slide 120 and the second slide 130. The rotating shielding component 140 is similar to the belt on the belt conveyor and is wound between the first slide 120 and the second slide 130. The rotating shielding component 140 includes a connected rolling curtain 141 and a pull rope 142, and the material of the rolling curtain 141 can be a thermal insulation cloth. Two U-shaped hook parts 143 are connected to the head and tail ends of the rolling curtain 141 respectively. The U-shaped hook parts 143 can be formed by bending stainless steel, and the U-shaped hook parts 143 are fixed to the rolling curtain 141 by rivets. A mounting box 150 is provided at the top of the air vent window 113, and a plurality of auxiliary slides 151 matching the rotating shielding part 140 are provided in the mounting box 150. Since the air vent window 113 is vertically arranged and the purlin 114 is inclined, and the rotating shielding part 140 needs to be arranged along the direction of the air vent window 113 and the purlin 114, the middle part of the rotating shielding part 140 will bend, and the auxiliary slides 151 are provided here to support the rotating shielding part 140 at the bending part. A T-shaped clamping block 152 is fixed in the installation box 150, and connecting ends 152a matching the U-shaped hook are formed at both ends of the T-shaped clamping block 152. When the rolling curtain 141 is pulled and rotated by pulling the pull rope 142, the U-shaped hooks at both ends of the rolling curtain 141 will be inserted into the connecting ends 152a of the T-shaped clamping block to complete the positioning. A pressing component 160 matching the U-shaped hook is provided on the wall body 111 below the ventilation window 113. The pressing component 160 is used to apply a downward pulling force to the U-shaped hook by its own gravity, so that the rolling curtain 141 can stably block the ventilation window 113.
[0022] In the embodiment of the present application, during the working process, when the sunshade needs to be pulled down in winter, the operator holds the pull rope 142 and pulls the rotating shielding component 140 clockwise, and the roller curtain 141 moves downward under the support of the first slide 120, the second slide 130 and multiple auxiliary slides 151 until the U-shaped hook at the upper end of the roller curtain 141 is inserted into the T-shaped card block. At this time, the upper end of the roller curtain 141 will be inserted into the T-shaped card block, and the T-shaped card block will apply an upward pulling force to the roller curtain 141. The upper end of the roller curtain 141 is supported and connected by the T-shaped card block. The operator hangs the downward pressing component 160 on the U-shaped hook at the lower end of the roller curtain 141. The lower end of the roller curtain 141 will be stretched and fixed by the downward pressing component 160. At this time, the installation process of the roller curtain 141 can be completed.
[0023] As can be seen from the above, in the embodiment of the present application, the original purlin 114 of the cowshed 110 is modified. The first slide 120, the second slide 130 and the plurality of auxiliary slides 151 are provided so that the rotating shielding component 140 does not need to be coiled inside the roll when stored, but always maintains the stretched form, thereby effectively avoiding the phenomenon that the rolling curtain 141 is corroded due to being in the shade and water bubble environment for a long time. By providing a U-shaped hook on the rolling curtain 141, and providing a T-shaped clamping block 152 and a pressing component 160 matching the U-shaped hook, the T-shaped clamping block and the pressing component 160 are used to position and limit the upper and lower ends of the rolling curtain 141 respectively after it is pulled down, thereby making the device more convenient and efficient during operation. Furthermore, the operator can quickly lift the rolling curtain 141 through the device when the temperature is suitable in winter, and perform ventilation operation in the cowshed 110 in time.
[0024] In some embodiments, the pressing component 160 includes a slide groove 161 vertically arranged on the wall body 111, a slider 162 is slidably arranged in the slide groove 161, and a first scraping hook 162a matching the U-shaped hook is rotatably arranged on the top of the slider 162. In the embodiment of the present application, a specific setting method of the pressing component 160 is shown. In the embodiment of the present application, the slider 162 can be made of cast iron, so that the slider 162 itself has a large gravity. When the rolling curtain 141 is pulled down, the operator lifts the slider 162 by holding the first hook, and then hangs the first hook on the U-shaped hook. At this time, the lower end of the rolling curtain 141 is subjected to force through the U-shaped hook, which will limit the movement of the lower end of the rolling curtain 141. Moreover, during use of the rolling curtain 141 (the material of the rolling curtain 141 is usually thermal insulation cloth), problems such as shrinkage or elongation may occur. In the embodiment of the present application, regardless of whether the rolling curtain 141 shrinks or elongates, the sliding of the slider 162 in the slide groove 161 can achieve adaptive adjustment, so that it can always be connected to the rolling curtain 141.
[0025] In some embodiments, a plurality of weight components 163 are detachably connected to the slider 162. In the embodiment of the present application, the weight block 163b is provided to increase the overall gravity of the slider 162, thereby making the slider 162 fix the lower end of the rolling curtain 141 more stably.
[0026] In some embodiments, the weight component 163 includes a bag 163a, which contains mud and sand. A second hook 162b is provided at the bottom of the slider 162, and the bag 163a is hung on the second hook 162b. Mud and sand and other materials can be obtained locally. After the mud and sand are loaded into the bag 163a, the bag 163a is hung on the slider 162 to achieve the weight of the slider 162.
[0027] In some embodiments, the counterweight component 163 includes a plurality of counterweight blocks 163b, the top and bottom ends of the plurality of counterweight blocks 163b are respectively provided with a sub-mouth and a female mouth, the bottom of the slider 162 is provided with a female mouth, and the plurality of counterweight blocks 163b and the slider 162 are sequentially connected end to end through the sub-mouth and the female mouth. In the embodiment of the present application, the counterweight block 163b can also be made of cast iron. Through the above arrangement, the counterweight block 163b can be easily disassembled through the letter mouth, and the number of counterweight blocks 163b connected can be selected according to actual needs.
[0028] In some embodiments, a hanging rod 170 matching the pull cord 142 is provided at the bottom of the ventilation window 113. Under normal circumstances, when the rolling curtain 141 is pulled up, the rolling curtain 141 will not slide down by itself due to the friction force. In rare cases, the rolling curtain 141 will naturally fall down after being pulled up under the influence of its own weight. Therefore, the above arrangement is made in the embodiment of the present application. After the rolling curtain 141 is pulled up, a part of the pull cord 142 can be wrapped around the hanging rod 170, so that the pulling cord 142 is connected to the hanging rod 170, and the pulling cord provides an upward pulling force for the rolling curtain 141, thereby preventing the rolling curtain 141 from sliding down by itself.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of the claims.
