Description

Technical Field

[0001] The utility model belongs to the technical field of building roofs, and more specifically, particularly relates to a roof anti-leakage structure. Background Art

[0002] Roof leakage is a common quality problem in housing construction. The penetration can be large or small. The direct cause of this problem is small cracks in the roof that cause leakage. The roofs of housing buildings generally use prefabricated reinforced concrete porous panels, which are waterproofed by using soft materials such as plastic ointment, modified asphalt and other plugging agents.

[0003] Based on the above, the inventors have discovered the following problems: However, as cracks are generated at the joints between the prefabricated panels due to factors such as thermal expansion, contraction or corrosion, the roof will inevitably leak, and a good anti-leakage effect cannot be achieved, resulting in the need to frequently apply plastic ointment, modified asphalt and other leak-proofing agents as waterproof materials for waterproofing, which is not only inconvenient but also requires construction to be carried out only when the weather is clear.

[0004] For example, the publication number CN218814809U is a building roof water-repellent and anti-seepage structure, which includes a frame, a rotating motor and two collecting boxes. The frame is internally rotatably connected with a ball screw, the left end of the ball screw penetrates the frame and is fixedly connected to the output end of the rotating motor power, the outer surface of the ball screw is threadedly connected with a moving frame, and two waterproof cloths are fixedly installed on the inner wall of the frame, the left side of each waterproof cloth is fixedly connected to the right side of the moving frame, the upper surface of each collecting box is fixedly connected with a conveying pipe, and both ends of each conveying pipe away from the collecting box penetrate the frame and extend to the inside of the frame; the utility model By providing a frame, a conveying pipe and a collection box, the purpose of collecting rainwater is achieved. By providing a rotating motor, a ball screw, a movable frame and a waterproof cloth, the purpose of preventing the roof from leaking is achieved, thereby preventing rainwater from entering the interior of the house through the cracks in the roof. Although the structure can effectively block rain, in actual use, rainwater will remain on the surface of the waterproof cloth, which will cause corrosion and damage to the rainproof cloth over time, reducing its service life. When the rain is heavy, the rainproof cloth will sag. Although the rainproof cloth is set at an angle, it is still obviously dented on a rainproof cloth with a larger area. The denting of the rainproof cloth is prone to water accumulation, which is not conducive to drainage. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a roof anti-leakage structure to solve the problem of poor waterproof effect by applying waterproof materials.

[0006] The utility model provides a roof anti-leakage structure, which is achieved by the following specific technical means:

[0007] A roof anti-leakage structure includes a storage box, which has at least one opening. Guide rails that extend obliquely downward are fixedly installed at both ends of the opening, a connecting shaft is movably installed inside the guide rail, and an elastically deformable arc-shaped wind shield is provided on the outer wall of the connecting shaft; one end of the rain shield is fixedly connected to the connecting shaft, and the other end is connected to the rotating shaft inside the storage box, the rain shield is in a double-layer configuration, the cloth surface of the lower rain shield near the rotating shaft is sewn with an elastic opening strip, the cloth surface of the lower rain shield near the connecting shaft is provided with an air outlet slot, the elastic opening strip corresponds to the air blowing port of a blower located at the bottom of the storage box and aligned with the ridge, the blower simultaneously blows air into a triangular area formed by the elastic opening strip, the rain shield and the roof, the area of ​​the air inlet in the triangular area is larger than the area of ​​the air outlet, and the arc-shaped wind shield is located at the air outlet of the triangular area.

[0008] Furthermore, the rotating shaft includes a driving shaft and a driven shaft; the driving assembly includes a servo motor, the power output end of the servo motor is fixed to the driving shaft, a driving gear is fixed to one end of the driving shaft, and a driven gear is fixed to one end of the driven shaft, and the driving gear and the driven gear are meshed with each other.

[0009] Furthermore, a slide is provided on one side of the guide rail, a roller is slidably connected inside the slide, a connecting shaft is coaxially connected to the roller, and counterweight blocks are fixed at the bottom of both ends of the outer wall of the connecting shaft.

[0010] Furthermore, a wiper assembly is fixed through the top of the storage box, and the wiper assembly includes an electric telescopic rod inclined and parallel to the width direction of the storage box, and a scraper rod abutting and cooperating with the upper surface of the rain shield cloth is fixed to the output end of the electric telescopic rod.

[0011] Furthermore, the length of the scraper rod is adapted to the width of the rain shield.

[0012] Furthermore, a water storage box is fixed on the top of the storage box, water guide grooves are opened on both sides of the inner wall of the water storage box, and a humidity sensor is fixed on the bottom of the inner wall of the water storage box.

[0013] Furthermore, a drainage hole is provided through one side of the water storage box.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, the storage box is installed on the roof, the support rod is fixed on one side of the roof, and the servo motor is controlled to rotate in the opposite direction. The counterweight block drives the connecting shaft to move toward the bottom of the guide rail, and the roller rolls inside the slide groove to reduce friction and prevent jamming, so that the rain shield is stretched out, and the roof is covered and shielded by the rain shield to divert rainwater, thereby achieving a comprehensive and better waterproof and anti-leakage effect.

[0016] 2. When the humidity sensor in the utility model detects rain, it will provide a signal to the electric telescopic rod to shorten it, and then provide a signal to the servo motor to make it rotate to release the rain shield. When the rain stops, the drainage hole will slowly drain the rainwater. When the humidity sensor cannot detect water, it will provide a signal to the electric telescopic rod to extend it, and then provide a signal to the servo motor to make it rotate to roll up the rain shield, thereby achieving the effect of automatically unfolding and waterproofing in rainy weather.

[0017] 3. In the utility model, the electric telescopic rod is extended at the same time when the rain shield is rolled up. The inclined electric telescopic rod allows the scraper rod to extend to the outside of the storage box until it is in contact with the top of the rain shield. A rubber strip is provided at the bottom of the scraper rod. When the rain shield is folded up, the scraper rod scrapes the outside of the rain shield to scrape off all the rain water, preventing the rain from soaking the rain shield for a long time and causing corrosion damage, and avoiding long-term exposure to sunlight, thereby achieving the effect of protecting the rain shield with multiple teams and increasing the service life of the rain shield.

[0018] 4. The utility model provides a roof leakage prevention structure, in which a blowing device is arranged at the bottom of the storage box. When the rain shield is unfolded, there is a triangular space between the rain shield and the roof. Starting the blowing device can form wind pressure in the triangular space between the rain shield and the roof, and the air is blown from top to bottom, with more air entering and less air leaving, which just makes the wind pressure in the triangular space large, forming a ground effect similar to that of the ground. This utilizes its own structure to solve the problem of the rain shield bending and sinking due to water accumulation.

[0019] 5. The utility model provides a roof anti-leakage structure, in which an arc-shaped wind shield is provided at the bottom end of the middle part of the outer wall of the connecting shaft, and the air blowing device blows air into the triangular area so that the air intake is greater than the air outlet. When the wind pressure in the triangular area exceeds a threshold value, the arc-shaped wind shield elastically deforms outward to suddenly increase the area of ​​the air outlet, thereby releasing the wind pressure in the triangular area and reducing the wind pressure. Subsequently, the arc-shaped wind shield automatically returns to its initial shape, and this process is repeated. In this way, the vibration of the rain shield can be increased, dust in the rainwater can be prevented from accumulating and adhering to the rain shield, thereby achieving a self-cleaning effect.

[0029] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0030] In the description of the present invention, unless otherwise specified, “plurality” means two or more; in addition, the terms “first”, “second”, “third”, etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0031] As attached Figure 1 To Attachment Figure 7As shown: the utility model provides a roof anti-leakage structure, including a storage box 1, which is made of high-strength weather-resistant material to ensure that it can maintain a good shape and function under long-term exposure to outdoor environment. The storage box 1 has at least one opening, and guide rails 2 are fixed at both ends of the opening. The guide rails 2 extend downward in an inclined manner to optimize the rainwater diversion path. A support rod 3 is fixed at the bottom of the guide rail 2, and the support rod 3 is mounted on the roof. A connecting shaft 5 is slidably connected inside the guide rail 2, one end of a rain shield 6 is fixedly connected to the connecting shaft 5, and the other end of the rain shield 6 is connected to the rotating shaft inside the storage box 1. A driving component is provided on the outer wall of the storage box 1 to drive the rotating shaft to rotate The rain shield 6 is dynamically retracted and has a double-layer configuration. An elastic opening strip 24 is sewn on the fabric surface of the lower rain shield 6 near the rotating shaft, and an air outlet slit 25 is provided on the fabric surface of the lower rain shield 6 near the connecting shaft 5. The opening area of ​​the air outlet slit 25 is smaller than the opening area of ​​the elastic opening strip 24. In the non-working state, the elastic opening strip 24 naturally droops, causing an open space to be formed between the rain shields 6. When the rain shield 6 is rolled up, the rain shield 6 is compressed so that the elastic opening strip 24 is flat and closed. At the same time, the air accumulated inside the rain shield 6 is squeezed out through the air outlet slit 25. This process helps to flatten the rain shield 6 for easy neat rolling up. The elastic opening strip 24 corresponds to the blowing port of the blowing device 19. The blowing device 19 is located at the bottom of the storage box 1 and is aligned with the ridge. The blowing device 19 blows air into the rain shield 6 through the elastic opening strip 24, so that wind pressure is generated in the rain shield 6 and the air intake is greater than the air outlet, thereby increasing the rigidity of the rain shield 6 when it is unfolded. At the same time, the blowing device 19 also blows air into the triangular area formed by the rain shield 6 and the roof. The junction of the rain shield 6 and the ridge constitutes the air inlet 20, and the edge of the rain shield 6 is close to the eaves. Part of it forms an air outlet 22, and the area of ​​the air inlet 20 is larger than the area of ​​the air outlet 22, thereby constructing a natural air flow channel. The blowing device 19 blows air in a directional manner at the air inlet 20, so that the wind can flow smoothly from the air inlet 20 to the relatively narrow air outlet 22, so that the air intake is greater than the air outlet. The resulting air volume difference is retained between the rain shield 6 and the roof, forming a wind pressure support similar to the ground effect, which avoids the situation where the middle part of the rain shield 6 is concave due to the excessive weight of the rain, causing rain retention.

[0032] In this embodiment, an elastically deformable arc-shaped wind shield 23 is provided on the outer wall of the connecting shaft 5, and the arc-shaped wind shield 23 is located at the air outlet 22 in the triangular area. The arc-shaped wind shield 23 is in an inwardly concave state under normal conditions. When the wind pressure in the triangular area exceeds a threshold value, the arc-shaped wind shield 23 elastically deforms outward in accordance with the pressure, causing the area of ​​the air outlet 22 to suddenly increase, thereby releasing the wind pressure in the triangular area and reducing the wind pressure. Subsequently, the arc-shaped wind shield 23 resets itself to its original shape by relying on its elasticity, and this dynamic adjustment process continues. The provision of the arc-shaped wind shield 23 not only enhances the natural vibration effect of the rain shield 6, but also effectively avoids the accumulation and adhesion of dust carried by rainwater on the surface of the rain shield 6, thereby realizing a self-cleaning function. At the same time, when the rain shield 6 is stored, the arc-shaped wind shield 23 closes the opening of the storage box 1, thereby effectively isolating the invasion of external dust and fine particles, thereby significantly improving the durability and service life of the entire structure.

[0033] In this embodiment, the rotating shaft includes a driving shaft 11 and a driven shaft 12, and the driving component includes a baffle plate 8 fixed to the outer wall of the storage box 1, a connecting rod 9 fixed to the bottom end of the baffle plate 8, and a servo motor 10 fixed to the bottom of the connecting rod 9. The power output end of the servo motor 10 is fixed to the driving shaft 11, a driving gear 13 is fixed to one end of the driving shaft 11, and a driven gear 14 is fixed to one end of the driven shaft 12. The driving gear 13 and the driven gear 14 are meshed with each other. The driving shaft 11 is driven by the servo motor 10 to rotate, and the rain shield 6 on one side is rolled up. The driving gear 13 and the driven gear 14 are meshed, and the driven shaft 12 is driven to rotate in the same speed and in the opposite direction to roll up the rain shield 6 on the other side.

[0034] In this embodiment, a slide groove 21 is opened on one side of the guide rail 2, and a roller 4 is slidably connected inside the slide groove 21. The connecting shaft 5 is coaxially connected to the roller 4, and counterweight blocks 7 are fixed to the bottom of both ends of the outer wall of the connecting shaft 5. When it is necessary to unfold the rain shield 6, the servo motor 10 is controlled to rotate in the opposite direction, and the counterweight block 7 drives the connecting shaft 5 to move to the bottom of the guide rail 2, and the roller 4 rolls inside the slide groove 21 to reduce friction and prevent jamming.

[0035] In this embodiment, a wiper assembly is fixed through the top of the storage box 1, and the wiper assembly includes an electric telescopic rod 17. The electric telescopic rod 17 is inclined and parallel to the width direction of the storage box 1, so that the electric telescopic rod 17 can be extended out of the storage box 1 when needed, so as to facilitate scraping off the rain at the end of the rain shield 6.

[0036] In this embodiment, a scraper rod 18 is fixed to the output end of the electric telescopic rod 17, which is in contact with the upper surface of the rain shield 6. The length of the scraper rod 18 is adapted to the width of the rain shield 6. When the rain shield 6 is retracted, the scraper rod 18 scrapes the outer surface of the rain shield 6 to scrape off all the rainwater, thereby preventing the rainwater from soaking the rain shield 6 for a long time and causing corrosion damage.

[0037] In this embodiment, a rubber strip is further provided at the bottom of the scraper rod 18. The rubber strip abuts against the rain shield 6 to increase friction, making the wiper more thorough. The rubber strip is made of a soft material and will not easily scratch the rain shield 6.

[0038] In this embodiment, a water storage box 15 is fixed on the top of the storage box 1, and water guide grooves 152 are opened on both sides of the inner wall of the water storage box 15. A humidity sensor 16 is fixed to the bottom of the inner wall of the water storage box 15. Water is stored through the water storage box 15. In rainy weather, rainwater flows from the water guide grooves 152 to the humidity sensor 16, and the humidity sensor 16 detects whether it is rainy weather.

[0039] In this embodiment, a drainage hole 151 is opened through one side of the water storage box 15, and the diameter of the drainage hole 151 is 4-8mm. The water is drained slowly. In rainy weather, water is kept inside the water storage box 15. When the rain stops, the water in the water storage box 15 can be drained. The humidity sensor 16 is electrically connected to the electric telescopic rod 17 and the servo motor 10 respectively. When the humidity sensor 16 detects rain, the humidity sensor 16 will collect humidity data. The wireless sensor encodes the measured humidity data into a wireless signal and sends it to the receiver installed on the electric telescopic rod 17 and the servo motor 10. The receiver will provide a wireless signal to the electric telescopic rod 17 to shorten it. At the same time, the receiver will also provide a wireless signal to the servo motor 10 to make it rotate to release the rain shield 6. When the rain stops, the drainage hole 151 will slowly drain the rainwater. When the humidity sensor 16 cannot detect water, it will provide a wireless signal to the receiver on the electric telescopic rod 17 to extend it, and then provide a wireless signal to the servo motor 10 to make it rotate to roll up the rain shield 6.

[0040] The specific usage of this embodiment is as follows:

[0041] In the utility model, the storage box 1 is first installed on the roof, and then the support rod 3 is fixed on one side of the roof, and the guide rail 2 is fixed on the support rod 3. In rainy weather, rainwater flows from the water guide groove 152 to the humidity sensor 16, and the humidity sensor 16 detects whether it is rainy weather. When the humidity sensor 16 detects rain, it will provide a wireless signal to the electric telescopic rod 17 to shorten it, and at the same time provide a wireless signal to the servo motor 10 to rotate it to release the rain shield 6. By controlling the servo motor 10 to rotate in the opposite direction, the counterweight block 7 drives the connecting shaft 5 to move to the bottom of the guide rail 2, and the roller 4 rolls inside the slide groove 21 to reduce friction and prevent it from getting stuck, so that the rain shield 6 is stretched out, and the blowing device 19 blows air into the elastic opening strip 24 to generate wind pressure between the rain shield 6 and increase the rigidity of the rain shield 6. At the same time, the blowing device 19 also blows air into the triangular space formed by the rain shield 6 and the roof, and adjusts the air intake to be greater than the air outlet, so that the rain shield 6 forms a ground effect similar to that of the ground to prevent it from being concave. When the wind pressure in the triangular area exceeds the threshold, the arc-shaped wind shield 23 elastically deforms outward in response to the pressure, causing the area of ​​the air outlet 22 to suddenly increase, thereby releasing the wind pressure in the triangular area and reducing it. The arc-shaped wind shield 23 then resets itself to its original shape by relying on its elasticity, and this process is repeated over and over again.

[0042] When the rain stops, the drainage hole 151 will slowly drain the rainwater. When the humidity sensor 16 cannot detect water, it will provide a wireless signal to the electric telescopic rod 17 to extend it, and at the same time provide a wireless signal to the servo motor 10 to make it rotate to roll up the rain shield 6. The servo motor 10 drives the driving shaft 11 to rotate, and rolls up the rain shield 6 on one side. The driving gear 13 and the driven gear 14 are engaged, driving the driven shaft 12 to rotate in the same speed and in the opposite direction to roll up the rain shield 6 on the other side. At the same time, the blowing device 19 is closed, and the blowing device 19 no longer supplies air to the elastic opening strips 24 on the rain shield 6, causing the wind pressure between the fabrics of the rain shield 6 to gradually decrease. As the rain shield 6 curls and squeezes each other, the residual wind pressure inside is discharged by the air outlet slits. 25 is released, and at the same time, the elastic opening strip 24 is naturally straightened due to the pressure, which is conducive to the smoother and tighter rolling of the rain shield 6. Then the electric telescopic rod 17 is extended, and the inclined electric telescopic rod 17 allows the scraper rod 18 to extend to the outside of the storage box 1 until it is fitted with the very end of the rain shield 6. A rubber strip is arranged at the bottom of the scraper rod 18. When the rain shield 6 is folded up, the scraper rod 18 scrapes the outside of the rain shield 6 to scrape off all the rain water, preventing the rain water from soaking the rain shield 6 for a long time and causing corrosion damage. When the arc-shaped wind shield plate 23 moves smoothly up to the terminal position along the guide rail 2 with the connecting shaft 5, the opening of the storage box 1 is closed, which effectively isolates the invasion of external dust and fine particles, and significantly improves the durability and service life of the entire structure.
