Description

Technical Field

[0001] This utility model relates to the field of sunshade curtain technology, and in particular to a waterproof and light-transmitting sunshade curtain for a production shed. Background Technology

[0002] Waterproof, light-transmitting, and sun-shading tarpaulins for agricultural production greenhouses are functional covering materials specifically designed for these facilities. Their core function is to adapt to the growth needs of crops within the greenhouse while simultaneously mitigating the impact of the outdoor environment. They are a crucial facility for balancing crop growth and outdoor environmental protection, and are widely used for covering various fruits, vegetables, seedlings, and other crops in production greenhouses.

[0003] Existing shading curtains for production sheds present two major problems in practical use: First, regarding waterproofing and drainage during the rainy season, existing curtains generally cover a large area, and during the rainy season, these depressions easily accumulate rainwater, forming "water pockets." As rainfall increases, the water accumulation in these "water pockets" continuously increases, and the weight rapidly rises. This not only significantly increases the load on the production shed frame, but the frame, under prolonged overload, is prone to metal fatigue, and in extreme cases, may even lead to the collapse of the entire shed. At the same time, the gravity generated by the accumulated water exerts continuous tension on the curtain, causing the partial stress on the curtain to far exceed its design capacity, shortening the curtain's lifespan. Second, regarding later maintenance and replacement, existing curtains mostly adopt an integral design. When the curtain is partially damaged due to accidental scratches during use, or when it ages due to long-term exposure to the outdoor environment and exposure to ultraviolet rays and wind and rain, it is impossible to repair or replace the damaged or aged parts individually. The entire curtain must be removed from the shed and replaced as a whole. This process not only requires multiple staff members to work together, consuming a lot of time and manpower, but also requires the purchase of a brand new, large-area screen, which is very expensive. Especially for production sheds with a large coverage area, the cost of materials and labor for a single replacement can reach several thousand yuan, which will bring a heavy economic burden to users in the long run.

[0004] In response to this technical problem, this application proposes a waterproof, light-transmitting, and sun-shading curtain for production sheds. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing technologies, such as easy water accumulation during the rainy season, which leads to water pockets, increased load on the frame and potential hazards to the tent structure, shortened lifespan of the curtain, and the need for complete replacement of damaged sections due to the integral design, which is labor-intensive and costly. Therefore, this utility model proposes a waterproof, light-transmitting, and sun-shading curtain for producing tents.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A waterproof, light-transmitting, and sun-shading curtain for a production shed includes a fabric body. Connecting horizontal plates are fixedly connected to both the front and rear ends of the fabric body. Each connecting horizontal plate has a pre-reserved slot on one of its opposite sides. A connecting bracket is provided between the two connecting horizontal plates at their adjacent ends. The inner wall of the connecting bracket has two pre-reserved slots on both its front and rear sides. The inner wall of the second pre-reserved slot is connected to the inner wall of the first pre-reserved slot at its adjacent end via a connecting component. Edge sleeves are fixedly connected to the left and right edges of the fabric body. Multiple drainage notches are provided on the top side of the edge sleeves. A flow-guiding strip is fixedly connected to the top side of the fabric body, with its left and right ends fixedly connected to the adjacent sides of the edge sleeves.

[0008] Furthermore, the cross-section of the connecting bracket is I-shaped, and the inner walls of the front and rear sides of the connecting bracket are fitted to the outer side of the connecting cross plate.

[0009] Furthermore, the outer wall of the connecting cross plate is provided with sealing grooves on both the top and bottom sides, and the inner wall of the connecting card seat is fixedly connected with a sealing strip that matches the sealing groove.

[0010] Furthermore, the connecting assembly includes two insert rods, which are detachably connected to the inner walls of the reserved slot one and the reserved slot two, respectively, and a fixed connecting plate is fixedly connected to the outer wall of the two insert rods on the side close to each other.

[0011] Furthermore, the left end of the insertion rod passes through the connecting bracket and is threaded with a fixing nut.

[0012] Furthermore, a waterproof pad is fitted on the right side of the outer wall of the two ends of the insertion rod, and the right side of the waterproof pad is fixed to the connecting bracket by fixing bolts.

[0013] Furthermore, the cross-section of the flow guide strip is arc-shaped, and the thickness of the flow guide strip gradually decreases from the middle to both ends.

[0014] Furthermore, there are multiple flow guide strips, and the multiple flow guide strips are distributed at equal intervals along the length of the fabric, with the distance between two adjacent flow guide strips being 30 to 40 cm.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, multiple fabric pieces can be detachably spliced ​​through connecting brackets and connecting components. When a fabric piece is scratched or aged, the connecting cross plate of the corresponding fabric piece can be separated from the connecting bracket, and the damaged fabric piece can be replaced individually. The replacement cost of a single fabric piece is only 1 / 5 to 1 / 10 of the overall screen, and the replacement process does not require dismantling the entire screen system, which significantly reduces the later maintenance cost and avoids the resource waste problem of "partial damage and overall scrapping" of existing screens.

[0017] 2. In this utility model, by setting a flow guide strip with an arc-shaped cross-section and evenly distributed along the length direction on the top side of the fabric, a large area of ​​fabric can be divided into multiple independent flow guide areas. The arc-shaped structure can guide rainwater to flow quickly to both sides of the edge by gravity, avoiding rainwater from stagnating and accumulating on the surface of the fabric. At the same time, the reinforcement effect of the flow guide strip can improve the overall tensile strength of the fabric, reduce the damage to the curtain caused by water accumulation, and, together with the drainage gap on the edge sleeve, quickly drain rainwater, effectively reducing the load on the tent frame.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3An embodiment of this utility model provides: a waterproof and light-transmitting shading curtain for a production shed, comprising a fabric body 1, with connecting horizontal plates 2 fixedly connected to both the front and rear ends of the fabric body 1, and a reserved slot 3 provided on each of the opposite sides of the connecting horizontal plates 2, and a connecting seat 4 provided between the connecting horizontal plates 2 at the near ends of the two fabric bodies 1, with reserved slots 5 provided on both the front and rear sides of the inner wall of the connecting seat 4, and the inner wall of the reserved slot 5 being connected to the inner wall of the reserved slot 3 at the near end through a connecting component, with edge sleeves 14 fixedly connected to the left and right edges of the fabric body 1, and multiple drainage gaps 15 provided on the top side of the edge sleeves 14, and a flow guide strip 13 fixedly connected to the top side of the fabric body 1, with the left and right ends of the flow guide strip 13 fixedly connected to the near side of the edge sleeves 14;

[0026] Specifically, fabric 1, serving as the core carrier for sun shading, waterproofing, and light transmission, has connecting horizontal plates 2 fixedly connected to its front and rear ends. These connecting horizontal plates 2 not only reinforce and shape the ends of fabric 1, preventing tearing at the edges due to long-term stress, but also provide a stable connection base for splicing adjacent fabric 1 pieces. Each side of the connecting horizontal plate 2 has a pre-reserved slot 3, which precisely matches the connecting components, ensuring accurate positioning between the connecting components and the connecting horizontal plate 2. The connecting horizontal plates 2 at the adjacent ends of the two fabric 1 pieces... A connecting bracket 4 is provided between the two adjacent fabric pieces 1, which can effectively connect the connecting cross plates 2 of two adjacent fabric pieces 1, realizing flexible splicing of multiple fabric pieces 1 to meet the needs of production sheds of different sizes. The inner wall of the connecting bracket 4 has reserved slots 2 5 on both the front and back sides. The reserved slots 2 5 correspond to the reserved slots 1 3, providing dual installation positioning points for the connecting components, ensuring a flat structure after splicing adjacent fabric pieces 1. The inner wall of the reserved slot 2 5 is connected to the inner wall of the reserved slot 1 3 at the adjacent end through the connecting components. The connecting component allows for the detachable fixing of the connecting plate 2 and the connecting bracket 4, facilitating the maintenance and replacement of the fabric 1 later. Edge sleeves 14 are fixedly connected to both the left and right edges of the fabric 1. These edge sleeves 14 protect the sides of the fabric 1, reducing frictional wear between the sides and external structures, and preventing rainwater from seeping in through the gaps on the sides of the fabric 1. Multiple drainage holes 15 are provided on the top side of the edge sleeves 14, allowing rainwater collected at the top of the edge sleeves 14 to drain quickly, preventing rainwater from accumulating at the edges. Retention leads to leakage. A guide strip 13 is fixedly connected to the top side of the fabric 1. The guide strip 13 can enhance the structural strength of the fabric 1 and reduce the swaying of the fabric 1 under the action of wind. On the other hand, it can guide the rainwater on the surface of the fabric 1, so that the rainwater can flow quickly along the direction of the guide strip 13 to the edge sleeve 14, and then be discharged through the drainage gap 15. The left and right ends of the guide strip 13 are fixedly connected to the adjacent side of the edge sleeve 14, thus forming a complete rainwater guiding path and further improving the overall waterproof effect.

[0027] Reference Figures 2-4The connecting bracket 4 has an I-shaped cross-section, and the inner walls of the front and rear sides of the connecting bracket 4 are fitted to the outer side of the connecting horizontal plate 2. Sealing grooves 11 are provided on the top and bottom sides of the outer wall of the connecting horizontal plate 2. A sealing strip 12, compatible with the sealing groove 11, is fixedly connected to the inner wall of the connecting bracket 4. The connecting assembly includes two insert rods 6, which are detachably connected to the inner walls of the reserved slot 1 3 and the reserved slot 2 5, respectively. A fixed connecting plate 7 is fixedly connected to the side of the outer wall of the two insert rods 6 that is close to each other. The left end of the insert rod 6... A connecting bracket 4 is threaded with a fixing nut 8; a waterproof pad 9 is fitted on the right side of the outer wall of the two end inserts 6, and the right side of the waterproof pad 9 is fixed to the connecting bracket 4 by a fixing bolt 10; the cross-section of the flow guide strip 13 is arc-shaped, and the thickness of the flow guide strip 13 gradually decreases from the middle to both ends; there are multiple flow guide strips 13, and the multiple flow guide strips 13 are evenly distributed along the length direction of the fabric 1, and the distance between two adjacent flow guide strips 13 is 30-40cm;

[0028] Specifically, the I-shaped structure allows the inner walls of the front and rear sides of the connecting bracket 4 to fit tightly against the outer side of the connecting horizontal plate 2. This ensures the contact area between the connecting bracket 4 and the connecting horizontal plate 2, improving connection stability, and also limits the front and rear sides of the connecting horizontal plate 2, preventing it from shifting after splicing. The inner walls of the front and rear sides of the connecting bracket 4 fit tightly against the outer side of the connecting horizontal plate 2. Sealing grooves 11 are provided on the top and bottom sides of the outer wall of the connecting horizontal plate 2. A sealing strip 12, compatible with the sealing groove 11, is fixedly connected to the inner wall of the connecting bracket 4. When the connecting horizontal plate 2 and the connecting bracket 4 are joined, the sealing strip 12 embeds into the sealing groove 11, filling the gap between them and effectively preventing rainwater from seeping in from the connection point, significantly improving the sealing and waterproofing performance of the splice. The component includes two insert rods 6, which are detachably connected to the inner walls of the first and second pre-reserved slots 3 and 5, respectively. The insert rods 6 can achieve precise positioning of the connecting cross plate 2 and the connecting seat 4 through the pre-reserved slots 3 and 5, ensuring accurate connection. A fixing connecting plate 7 is fixedly connected to the outer wall of the two insert rods 6 on the side closest to each other. The fixing connecting plate 7 connects the two insert rods 6 into a whole, improving the structural strength of the insert rods 6 and ensuring that the two insert rods 6 are subjected to force synchronously, preventing loosening of a single insert rod 6 due to uneven force. The left end of the insert rod 6 passes through the connecting seat 4 and is threaded with a fixing nut 8. By tightening the fixing nut 8, axial pressure can be applied to the insert rod 6, making the insert rod 6 tightly engaged in the pre-reserved slots 3 and 5. Inside, the connection between the connecting horizontal plate 2 and the connecting bracket 4 is further reinforced, and the threaded connection facilitates later disassembly and maintenance; a waterproof pad 9 is fitted on the right side of the outer wall of the insert rods 6 at both ends. The waterproof pad 9 can fill the gap between the insert rod 6 and the inner wall of the reserved slot, and at the same time play a waterproof sealing role, preventing rainwater from seeping in along the gap between the insert rod 6 and the slot. The right side of the waterproof pad 9 is fixed to the connecting bracket 4 by a fixing bolt 10. The fixing bolt 10 can firmly fix the waterproof pad 9 on the connecting bracket 4, preventing the waterproof pad 9 from shifting during long-term use and ensuring a long-lasting and stable waterproof effect; the cross-section of the guide strip 13 is arc-shaped. The arc structure allows rainwater to flow quickly along the arc surface under the action of gravity, reducing the residence time of rainwater on the surface of the fabric 1, and guiding... The thickness of the flow guide strip 13 gradually decreases from the middle to both ends. This thickness design ensures the structural strength of the middle part of the flow guide strip 13 while reducing the weight at both ends, preventing the fabric 1 from sagging due to excessive weight of the flow guide strip 13. There are multiple flow guide strips 13, and the multiple flow guide strips 13 are evenly distributed along the length of the fabric 1. The evenly distributed flow guide strips 13 can divide the surface of the fabric 1 into multiple independent flow guide areas, so that rainwater is evenly distributed and drainage efficiency is improved. The distance between two adjacent flow guide strips 13 is 30-40cm. This distance can ensure the drainage effect of each flow guide area without increasing the overall weight of the fabric 1 due to too many flow guide strips 13, thus achieving a balance between practicality and economy.

[0029] Working Principle: When in use, this curtain uses a drive shaft as the power source. After the drive shaft starts, it outputs power to the transmission system. The transmission system transmits the power to the reversing wheel, causing it to rotate. The reversing wheel changes the direction of power transmission through its own wheel structure, ensuring that the power can match the rotation requirements of the winding drum. The winding drum rotates under the power transmitted by the transmission system. When the winding drum rotates forward, it winds up the coated steel cable. When the winding drum rotates in the reverse direction, it releases the coated steel cable. One end of the coated steel cable is fixedly connected to the winding drum, and the other end is fixedly connected to the movable edge of the waterproof curtain fabric at the other end of the scaffold. When rolled up, the movable edge of the waterproof curtain is pulled towards the winding drum, thus retracting the waterproof curtain. When the coated steel cable is released, the movable edge of the waterproof curtain moves away from the winding drum under its own weight or the action of the auxiliary mechanism, thus unfolding the waterproof curtain. The unfolding of the waterproof curtain can effectively block external rainwater. Combined with the waterproof performance of the fabric 1, the guiding effect of the flow-guiding strip 13, and the drainage function of the edge sheath 14, a comprehensive waterproof system is formed to achieve the purpose of waterproofing. At the same time, the fabric 1 in the unfolded state can also block strong light to achieve a sunshade effect, while the retracted state can ensure the light transmission requirements inside the production shed.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
