Description

Technical Field

[0001] This invention belongs to the field of roof waterproofing technology, and in particular relates to an automatic drainage roof waterproofing component. Background Technology

[0002] A building roof is the covering and enclosure system that is directly exposed to the outside world on the top of a building. It is the surface layer of the roof and its main functions are waterproofing and drainage, thermal insulation, and protection against wind, rain, snow, and ultraviolet rays. It also has load-bearing, aesthetic, and energy-saving functions. It is a sub-project of the building. Building roof waterproofing components refer to the structural parts and accessories specifically used for waterproofing, water-stopping, sealing, termination, and joint treatment. They are not the large rolls of material or paint itself, but key components for solving high-leaking nodes, such as flashing, rain gutters, eaves gutters, etc. In short, waterproofing components are special waterproofing parts for all nodes, terminations, junctions, drainage, and sealing of the roof. They are the key parts for controlling leakage.

[0003] In traditional roof waterproofing components, gutter components tend to accumulate debris, silt, and residual water stains on their inner walls after long-term use. Manual cleaning is laborious and not timely enough. Over time, this accumulation can clog drainage channels, preventing water from draining from the roof and leading to leaks in the gutter or roof. To solve these problems, there is an urgent need for an automatic drainage roof waterproofing component. Summary of the Invention

[0004] The purpose of this invention is to address the problem that after long-term use, debris, silt, and residual water stains easily adhere to the inner wall of gutters, making manual cleaning laborious and untimely. Long-term accumulation can clog drainage channels, preventing water from draining from the roof in a timely manner and leading to leaks in gutters or roofs. Therefore, this invention proposes an automatic drainage waterproof building roof component.

The side plates are provided with wave grooves, transverse grooves and inclined push grooves.

[0006] As a further description of the above technical solution: The wave groove is disposed between two transverse grooves and the wave groove and the transverse groove are interconnected. The end of the transverse groove away from the wave groove is connected to the lowest end of the inclined push groove. The fixing plate is disposed between two side plates and contacts the side plates. The connecting block slides in the wave groove, the transverse groove and the inclined push groove.

[0007] As a further description of the above technical solution: The fixed base has multiple fixing holes on both sides and multiple fixing strip holes on both sides. The fixing holes and fixing strip holes are arranged alternately at equal intervals. The output shaft of the drive motor is connected to the auxiliary connecting shaft.

[0008] As a further description of the above technical solution: A protective layer is provided on the outer wall of the drainage gutter, a water-blocking layer is provided on the inner wall of the drainage gutter, and a waterproof layer is provided between the protective layer and the water-blocking layer. The protective layer, the water-blocking layer and the waterproof layer are fixedly connected to each other. The protective layer is made of fluorocarbon coated aluminum alloy, the water-blocking layer is made of silicone rubber, and the waterproof layer is specifically a polymer waterproof membrane.

[0009] As a further description of the above technical solution: The push scraper is inserted into the slot, and the wall of the push scraper is in close contact with the water-blocking layer of the drainage gutter. Positioning slots are provided on both sides of the slot, and the positioning block is inserted into the positioning slot through the wall of the push scraper.

[0010] As a further description of the above technical solution: One end of the connecting spring is fixedly connected to the lower part of the insert plate, the wall of the insert plate is in close contact with the wall of the connecting groove, and the connecting rod is rotatably connected to the connecting plate through a bearing.

[0011] As a further description of the above technical solution: The pull rod is T-shaped in shape. The narrow end of the T-shape is fixedly connected to the movable rod, and a connecting cap is slidably connected through the narrow end of the T-shape. The connecting cap is threaded into the threaded sleeve, and the outer wall of the connecting cap is provided with anti-slip texture. A fixing ring is fixedly connected to the movable rod. One end of the return spring is fixedly connected to the fixing ring, and the other end of the return spring is fixedly connected to the guide groove wall.

[0012] As a further description of the above technical solution: Both the movable rod and the connecting strip slide within the guide groove. The movable plate is in close contact with the wall of the guide groove, and an opening is provided on the movable plate. Opening grooves are provided on the walls of the opening on both sides of the movable plate. The opening grooves are inclined, and the opening grooves on the two movable plates form a V-shaped structure. The connecting strip is disposed within the opening and in contact with the wall of the cavity. The push block slides within the opening groove.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by starting the drive motor to rotate the secondary connecting shaft, the secondary connecting shaft drives the secondary synchronous pulley to rotate. Then, through the transmission cooperation of the main synchronous pulley, the secondary synchronous pulley, and the toothed synchronous belt, the toothed synchronous belt drives the fixed block to reciprocate on one side of the drainage gutter. The fixed block, in turn, drives the mounting plate to move together, causing the mounting plate to slide the push scraper from one end of the drainage gutter to the other end. During this process, the inclined push groove on one end of the drainage gutter pushes the connecting block, causing the mounting plate to move downwards and synchronously drive the connecting plate. This allows the insert plate to slide into the connecting groove and compress the connecting spring, thereby causing the brush below the push scraper to tightly adhere to the water-blocking layer on the inner wall of the drainage gutter. As the push scraper continues to move, the brush can clean the debris and silt adhering to the surface of the water-blocking layer. And residual water stains. When the connecting block slides from the transverse groove at one end into the corrugated groove, the tortuous groove wall of the corrugated groove will push the connecting block back and forth, causing the mounting plate to deflect back and forth around the connecting rod, thereby driving the pusher blade to swing back and forth at a small angle to achieve the scraping action. As the pusher blade moves continuously, the connecting block will gradually slide from the corrugated groove into the transverse groove and the inclined pusher groove at the other end of the drainage gutter. The inclined pusher groove at the other end of the drainage gutter can push the connecting block upward, causing the mounting plate and the pusher blade to move upward. Thus, during the reciprocating movement of the pusher blade, the debris in the drainage gutter is scraped and pushed out from both ends of the drainage gutter by the pusher blade, achieving rapid cleaning of debris, avoiding debris accumulation and blockage, and draining accumulated water to avoid water leakage.

[0014] 2. In this invention, by inserting the scraper into the insertion slot, and then pressing down the pull rod, the pull rod pushes the movable rod and the connecting strip to slide in the guide groove. During this process, the connecting strip can slide in the opening, and the push blocks on both sides of the connecting strip can push against the skewed groove wall of the opening, causing the two movable plates to slide to both sides along the guide groove. The movable plates can simultaneously drive the positioning blocks to extend outward until the positioning blocks penetrate the wall of the scraper and insert into the positioning grooves on both sides of the insertion slot, thereby completing the rapid positioning and assembly of the scraper and the mounting plate. Then, the connecting cap is pressed down and twisted to make the connecting cap and the threaded sleeve threaded together. Simultaneously, it abuts against the end of the movable rod, thereby locking the position of the movable rod and preventing accidental sliding. This prevents the positioning block from coming out of the positioning groove, ensuring the connection stability between the push scraper and the mounting plate. This provides a guarantee for the subsequent scraping and drainage work of the push scraper. During the downward pressing process, the movable rod will drive the fixed ring to move down and stretch the return spring. Then, after the connecting cap is loosened, the return spring will drive the movable rod and the connecting strip to move up and reset, causing the connecting block to push against the wall of the opening groove in the opposite direction, causing the positioning block to detach from the positioning groove. This makes it easier for the staff to remove the push scraper for maintenance and replacement.

[0015] 3. In this invention, the drainage gutter employs a three-layer composite structure consisting of a protective layer, a waterproof layer, and a water-blocking layer, which effectively enhances its ability to resist external wind and rain erosion and ultraviolet radiation. The water-blocking layer enhances the sealing of the inner wall of the drainage gutter, preventing water from seeping into the interior, while the waterproof layer further strengthens the waterproof barrier. The triple protection effectively blocks the water seepage path and improves the overall waterproof effect. In addition, the alternating fixing holes and fixing strip holes on both sides of the fixing base allow for the reasonable arrangement of bolts according to needs, adapting to different waterproofing and drainage scenarios of building roofs.

The protective layer 201 is made of fluorocarbon coated aluminum alloy, and the water-blocking layer 202 is made of silicon. Made of rubber, the waterproof layer 203 is specifically a polymer waterproof membrane. A triple protection system is constructed through the protective layer 201, the water-blocking layer 202, and the waterproof layer 203. Among them, the fluorocarbon coated aluminum alloy protective layer 201 has the properties of resisting wind and rain erosion and resisting ultraviolet aging, while the silicone rubber water-blocking layer 202 can tightly adhere to the inner wall of the drainage gutter 2. Together with the polymer waterproof membrane waterproof layer 203, it forms an internal and external waterproof defense line. The triple protection is superimposed to form a complete water flow penetration blocking path, improving the waterproof effect of the drainage gutter 2.

[0020] A mounting cover 3 is fixedly installed on the other side above the mounting base 1. The drainage gutter 2 is fixedly connected to the mounting cover 3. Multiple fixing holes 101 and multiple fixing strip holes 102 are opened on both sides of the mounting base 1. The fixing holes 101 and fixing strip holes 102 are arranged alternately at equal intervals. The output shaft of the drive motor 5 is connected to the auxiliary connecting shaft 7. Through the alternating fixing holes 101 and fixing strip holes 102 on both sides of the mounting base 1, the bolts can be flexibly arranged according to the actual installation requirements of the building roof, adapting to the fixing requirements of different installation scenarios, and improving the versatility and stability of the installation.

[0021] A mounting bracket 4 is fixedly connected to one side of the mounting cover 3. A drive motor 5 is fixedly mounted on the mounting cover 3 via the mounting bracket 4. A main connecting shaft 6 is rotatably connected to one side of the mounting cover 3 via a bearing. A secondary connecting shaft 7 is rotatably connected to the other side of the mounting cover 3 via a bearing. A main synchronous pulley 8 is fixedly mounted on the main connecting shaft 6. A secondary synchronous pulley 9 is fixedly mounted on the secondary connecting shaft 7. A toothed synchronous belt 10 is mounted on both the main synchronous pulley 8 and the secondary synchronous pulley 9. A fixing block 11 is fixedly connected to the toothed synchronous belt 10. A connecting groove 12 is provided on the fixing block 11. Multiple connecting springs 13 are fixedly connected in the connecting groove 12. A through plate 14 is slidably connected in the connecting groove 12. A connecting plate 14 is fixedly connected above the through plate 14. A mounting plate 16 is rotatably mounted on one side of a connecting plate 15. A connecting rod 17 is fixedly connected to one side of the mounting plate 16. One end of a connecting spring 13 is fixedly connected to the lower part of an insert plate 14. The wall of the insert plate 14 is in close contact with the wall of the connecting groove 12. The connecting rod 17 is rotatably connected to the connecting plate 15 through a bearing. Through the contact between the insert plate 14 and the wall of the connecting groove 12, the insert plate 14 can slide in a straight line in the connecting groove 12, avoiding deflection and ensuring the smooth movement of the mounting plate 16. When the insert plate 14 slides in the connecting groove 12, the insert plate 14 can stretch or compress the connecting spring 13, and then the rebound of the connecting spring 13 assists in the reset movement of the connecting plate 15 and the mounting plate 16.

[0022] The mounting plate 16 has a slot 18 for inserting into it. A scraper 19 is inserted into the mounting plate 16 through the slot 18. The scraper 19 is inserted into the slot 18 and the wall of the scraper 19 is in close contact with the water-blocking layer 202 of the drainage gutter 2. Fixing plates 20 are fixedly connected to the lower sides of the mounting plate 16. Connecting blocks 21 are fixedly connected to the fixing plates 20. The scraper 19 has multiple drainage holes 22. The scraper 19 is located below the drainage holes 22. A brush 23 is fixedly installed, and a guide groove 24 is opened inside the upper part of the scraper 19. By inserting the scraper 19 into the insertion groove 18, the staff can easily and quickly position and install the scraper 19. The close contact between the scraper 19 and the water-blocking layer 202 can improve the scraping effect and assist in the drainage of accumulated water during the cleaning process, preventing water and debris from accumulating in the drainage gutter 2. The drainage strip hole 22 can reduce the water resistance encountered by the scraper 19 in the accumulated water.

[0023] A threaded sleeve 25 is fixedly connected above the scraper 19. A movable rod 26 is slidably connected through the threaded sleeve 25. A return spring 27 is sleeved on the movable rod 26. A pull rod 28 is fixedly connected to one end of the movable rod 26. The pull rod 28 is T-shaped. The narrow end of the T-shape of the pull rod 28 is fixedly connected to the movable rod 26. A connecting cap 38 is slidably connected through the narrow end of the T-shape of the pull rod 28. The connecting cap 38 is threaded into the threaded sleeve 25. The outer wall of the connecting cap 38 is provided with anti-slip texture. A [missing information - likely a typo, should be "fixed on the movable rod 26"]. The fixed ring 39 and the return spring 27 are fixedly connected at one end to the fixed ring 39 and at the other end to the guide groove 24. The anti-slip texture on the connecting cap 38 can increase friction, making it easy for the operator to twist and prevent slippage. When the connecting cap 38 is threadedly connected to the threaded sleeve 25, it can achieve thread self-locking, thereby firmly locking the position of the movable rod 26, preventing the movable rod 26 from sliding accidentally, and ensuring that the positioning block 32 is stably inserted into the positioning groove 37 to prevent accidental dislodgement.

[0024] A connecting strip 29 is fixedly connected to the other end of the movable rod 26. Push blocks 30 are fixedly connected to both sides of the connecting strip 29. Movable plates 31 are slidably connected to both sides inside the guide groove 24. A positioning block 32 is fixedly connected to one side of the movable plate 31. The movable rod 26 and the connecting strip 29 slide within the guide groove 24. The movable plate 31 is in close contact with the groove wall of the guide groove 24. An opening 40 is provided on the movable plate 31. Opening slots 41 are provided on the cavity walls on both sides of the opening 40 of the movable plate 31. The opening slots 41 are inclined and the opening slots 41 on the two movable plates 31 form a V with each other. The structure has a connecting strip 29 set inside the opening 40 and in contact with the cavity wall. The push block 30 slides in the opening slot 41. Positioning slots 37 are provided on both sides of the insertion slot 18. The positioning block 32 penetrates the wall of the push scraper 19 and is inserted into the positioning slot 37. Through the contact between the movable plate 31 and the wall of the guide slot 24, the guide slot 24 can limit and guide the movable plate 31, ensuring that the movable plate 31 moves smoothly and linearly and avoids tilting. In addition, the cavity wall of the opening 40 on the movable plate 31 restricts the connecting strip 29 and the movable rod 26 to prevent accidental twisting and displacement.

[0025] Side plates 33 are fixedly connected to both sides above the drainage gutter 2. The side plates 33 are provided with a wave groove 34, a transverse groove 35 and an inclined push groove 36. The wave groove 34 is located between the two transverse grooves 35 and the wave groove 34 and the transverse groove 35 are interconnected. The end of the transverse groove 35 away from the wave groove 34 is connected to the lowest end of the inclined push groove 36. The fixed plate 20 is located between the two side plates 33 and contacts the side plates 33. The connecting block 21 slides in the wave groove 34, the transverse groove 35 and the inclined push groove 36. Through the sliding cooperation of the connecting block 21 with the wave groove 34, the transverse groove 35 and the inclined push groove 36, the position adjustment and deflection of the mounting plate 16 and the push scraper 19 can be realized. The inclined push groove 36 can press down and push up the mounting plate 16, so that the brush 23 can make close contact with the inner wall of the drainage gutter 2 when the mounting plate 16 is pressed down, and the wave groove 34 can make the push scraper 19 swing back and forth, thereby improving the scraping effect.

[0026] Working principle: First, insert the scraper 19 into the insertion slot 18, then press down the pull rod 28 to push the movable rod 26 and the connecting strip 29 to slide in the guide groove 24. During this process, the connecting strip 29 can move down in the opening 40, while the push blocks 30 on both sides of the connecting strip 29 can push the skewed groove wall of the opening 41, causing the two movable plates 31 to slide to both sides along the guide groove 24. The movable plates 31 can simultaneously drive the positioning block 32, causing the positioning block 32 to penetrate the wall of the scraper 19 and insert into the positioning grooves 37 on both sides of the insertion slot 18, thereby completing the quick positioning combination of the scraper 19 and the mounting plate 16. Then, the connecting cap 38 is pressed down and twisted, causing the connecting cap 38 to be threadedly connected to the threaded sleeve 25, and simultaneously abutting against the end of the movable rod 26, thereby locking the position of the movable rod 26. During operation, the drive motor 5 is started to rotate the secondary connecting shaft 7, causing the secondary connecting shaft 7 to drive the secondary synchronous pulley 9 to rotate. Then, through the transmission cooperation of the main synchronous pulley 8, the secondary synchronous pulley 9 and the toothed synchronous belt 10, the toothed synchronous belt 10 can drive the fixed block 11 to move back and forth on one side of the drainage gutter 2. The fixed block 11 can drive the mounting plate 16 to move together, causing the mounting plate 16 to drive the push scraper 19 to slide from one end of the drainage gutter 2 to the other end of the drainage gutter 2. During the process, the inclined push groove 36 at one end of the drainage gutter 2 can push the connecting block 21, causing the mounting plate 16 to move down and simultaneously drive the connecting plate 15, so that the insert plate 14 can slide into the connecting groove 12 and compress the connecting spring 13, thereby making the brush 23 below the push scraper 19 closely adhere to the water-blocking layer 202 on the inner wall of the drainage gutter 2. As the push scraper 19 continues to move, the brush 23 can clean the debris, silt and residual water stains attached to the surface of the water-blocking layer 202. When the connecting block 21 slides from the transverse groove 35 at one end into the corrugated groove 34, the tortuous groove wall of the corrugated groove 34 will push the connecting block 21 back and forth, causing the mounting plate 16 to deflect back and forth around the connecting rod 17. This causes the scraper 19 to swing back and forth at a small angle, thus achieving a scraping action. As the scraper 19 moves continuously, the connecting block 21 gradually slides from the wave groove 34 into the horizontal groove 35 and the inclined push groove 36 at the other end of the drainage gutter 2. The inclined push groove 36 at the other end of the drainage gutter 2 can push the connecting block 21 upward, causing the mounting plate 16 and the scraper 19 to move upward. Then, the toothed synchronous belt 10 drives the scraper 19 to move back and forth to scrape the debris in the drainage gutter 2. The scraper 19 pushes the debris out from both ends of the drainage gutter 2 to achieve unblocking drainage.
