Description

Technical Field

[0001] This application relates to the technical field of drainage engineering, and in particular to a roof drainage system. Background Technology

[0002] Roof drainage is divided into organized drainage and unorganized drainage. Organized drainage refers to a drainage method in which rainwater from the roof is discharged to the outdoor ground or underground pipe trenches in an organized manner through the drainage system.

[0003] Chinese utility model patent CN208184085U discloses a roof rainwater drainage structure, including a roof and a rainwater hopper. The rainwater hopper is fixed to the roof and connected to a rainwater downpipe. When it rains, rainwater falls onto the roof, then is filtered through the rainwater hopper and flows into the rainwater downpipe for discharge.

[0004] People's activities and strong winds can leave debris on the roof. When it rains, rainwater carries the debris towards the rain gutters, where it is filtered out, while the rainwater enters and drains away. However, if the amount of debris increases or the rain gutters are not cleaned in time, they can easily become clogged, affecting roof drainage. Summary of the Invention

[0005] In order to clear rainwater hoppers when they become clogged, this application provides a roof drainage system.

[0006] This application provides a roof water supply and drainage system, which adopts the following technical solution:

[0007] A roof water supply and drainage system, including

[0008] A mounting base is disposed on the roof, and the mounting base has a receiving groove;

[0009] A rainwater pipe is installed on the mounting base, with the pipe opening located on the bottom wall of the receiving tank.

[0010] A rain cover is disposed at the opening of the rainwater pipe and located within the receiving groove, and the rain cover has multiple water filtering holes;

[0011] A connecting shaft is coaxially arranged with the rainwater pipe and is disposed on the inner wall of the rainwater cover;

[0012] A support shaft is rotatably connected to the bottom of the connecting shaft. The support shaft and the connecting shaft are coaxially arranged. The support shaft extends from inside the rain cover into the rain pipe.

[0013] A connecting arm is hinged to the support shaft and located inside the rain cover;

[0014] A cleaning brush is hinged to the connecting arm on the side away from the support shaft.

[0015] The cleaning brush bristles are positioned on the side of the cleaning brush away from the support shaft.

[0016] A guide ring surrounds the rain cover, and the guide ring has a guide surface that is inclined downward toward the rain cover;

[0017] The mounting base has a mounting groove that communicates with the receiving groove. The guide ring slides up and down in the mounting groove. When the rain cover is blocked, the guide ring slides down into the mounting groove.

[0018] An elastic drive element is disposed on the mounting base, and the elastic drive element drives the guide ring to protrude out of the mounting groove;

[0019] A drive assembly is disposed on the mounting base. When the guide ring slides up and down, the drive assembly drives the support shaft to rotate.

[0020] A power assembly is provided on the mounting base. When the guide ring slides into the mounting groove and the support shaft rotates, the power assembly controls the connecting arm to flip upward.

[0021] When the guide ring slides out of the mounting groove and the support shaft rotates, the power component controls the connecting arm to flip downwards;

[0022] When the connecting arm is flipped to a horizontal position, the cleaning bristles pass through the water filter holes to the outside of the rain cover.

[0023] By adopting the above technical solution, when the filter holes are clogged, water accumulates between the rain cover and the guide ring, and the water level continuously rises. At this time, the guide ring, under the gravity of the accumulated water, begins to slide downwards into the mounting groove. As the guide ring slides downwards, the drive component drives the support shaft to rotate, and at the same time, the power component drives the connecting arm to move upwards, causing the cleaning brush to follow the movement of the connecting arm until the cleaning brush bristles can pass through the filter holes to the outside. Simultaneously, during the rotation of the support shaft, the cleaning brush bristles follow the cleaning brush in a circumferential movement, cleaning the filter holes within the corresponding range when the rain cover is clogged, which helps to unblock the filter holes and allows rainwater to continue to be discharged through the rainwater pipe.

[0024] Optionally, the drive assembly includes a drive gear, a drive rack, a drive shaft, a transmission helical gear, a transmission shaft, a connecting helical gear, and a drive belt;

[0025] A drive groove is formed in the mounting base, the drive shaft is rotatably connected to the mounting base and located in the drive groove, and the drive gear is disposed on the outer periphery of the drive shaft;

[0026] The drive rack is disposed at the bottom of the guide ring, the drive rack slides up and down on the mounting base and protrudes into the drive groove, and the drive rack meshes with the drive gear;

[0027] The drive shaft rotates on the mounting base and is located within the drive groove, and the drive shaft is perpendicular to the drive shaft;

[0028] The transmission helical gear is disposed on the outer periphery of the transmission shaft, and the connecting helical gear is disposed on the outer periphery of the drive shaft. The transmission helical gear meshes with the connecting helical gear.

[0029] The drive belt slides through the mounting base and the rainwater pipe, and the drive belt is linked to the transmission shaft and the support shaft.

[0030] By adopting the above technical solution, the drive rack drives the drive shaft to rotate, and then the connecting helical gear drives the transmission shaft to rotate through the transmission helical gear, so that the support shaft enters the rotation state under the action of the drive belt.

[0031] Optionally, the drive shaft includes a bushing, a shaft body, and a coil spring;

[0032] The shaft and the bushing are rotatably connected to the mounting base, and the bushing is disposed on the outer periphery of the shaft and coaxially arranged.

[0033] The coil spring is wound around the outer periphery of the shaft body, with one end of the coil spring engaged with the shaft body and the other end engaged with the bushing.

[0034] The mounting base is slidably provided with a plug-in post, and the outer periphery of the drive shaft is formed with a plug-in groove for the plug-in post to be inserted into.

[0035] The mounting base is provided with a control component. When the drive rack slides down to near the bottom wall of the drive groove, the control component controls the plug to disengage from the plug groove.

[0036] When the drive rack slides upward to the bottom wall near the insertion post, the control component controls the insertion post to insert into the insertion slot.

[0037] By adopting the above technical solution, when the plug-in post disengages from the plug-in slot, the shaft enters a rotating state, causing the coil spring to be released instantly, increasing the rotation speed of the support shaft, improving the cleaning effect of the cleaning brush bristles, and reducing the possibility of rainwater entering the rain cover when a small number of filter holes are blocked, thereby causing the guide ring to slide out of the installation slot.

[0038] Optionally, the control component includes a control block, a control column, and a push block;

[0039] The control column is disposed on the side wall of the drive rack, and the push block is disposed on the side wall of the control column;

[0040] A control groove is formed on the outer periphery of the plug-in post for the push block to slide up and down. The plug-in post is inclined to form a push surface located in the control groove. When the push block slides on the push surface, the plug-in post disengages from the plug-in groove.

[0041] The control block is disposed on the side wall of the drive rack and is located below the control post. The control block is inclined to form a control surface for the insertion post to slide. When the insertion post slides on the control surface, the insertion post slides toward the insertion slot.

[0042] By adopting the above technical solution, when the push block slides on the push surface, the plug-in post disengages from the plug-in slot, which is conducive to the shaft entering the rotation state; when the plug-in post slides on the control surface, the plug-in post moves towards the plug-in slot, which is conducive to pushing the plug-in post into the plug-in slot, so that the shaft enters the stationary state.

[0043] Optionally, the plug-in post includes an inner post, an outer post, and a connecting spring;

[0044] The inner column slides on the outer column, and the connecting spring is disposed inside the outer column. One end of the connecting spring is fixed to the inner column, and the other end is fixed to the outer column.

[0045] By adopting the above technical solution, when the inner column is not aligned with the insertion slot, the connecting spring enters a compressed state, and the outer column can continue to move towards the insertion slot.

[0046] Optionally, the power assembly includes a power sleeve, a power column, and a power bar;

[0047] The power sleeve is threaded to the outer periphery of the connecting shaft, and the power bar is fixed to the outer periphery of the power sleeve and perpendicular to the connecting shaft;

[0048] The power strip has an oblong hole, the power column passes through the oblong hole, a limit block is provided at the top of the power column, and the bottom of the power column is hinged to the connecting arm.

[0049] By adopting the above technical solution, when the connecting arm rotates, the power column drives the power sleeve to rotate through the power bar, and the power sleeve is connected to the connecting shaft through a thread to achieve up and down movement.

[0050] Optionally, the connecting arm is provided with a torsion spring, which drives the cleaning brush to rotate away from the support shaft;

[0051] The connecting arm is provided with a limiting block. When the cleaning brush is flipped to be parallel to the connecting arm, the limiting block restricts the cleaning brush from continuing to flip away from the support axis.

[0052] By adopting the above technical solution, when the cleaning brush cleans the rain cover, the torsion spring pushes the cleaning brush towards the water filter holes, reducing the possibility of the cleaning brush flipping towards the support shaft during the cleaning process.

[0053] Optionally, the elastic driving element is a driving spring, which is installed in the receiving groove;

[0054] One end of the drive spring abuts against the guide ring, and the other end abuts against the bottom wall of the receiving groove.

[0055] By adopting the above technical solution, the drive spring drives the guide ring to move upward. The drive spring has a simple structure and is easy to use.

[0056] In summary, this application includes at least one of the following beneficial effects:

[0057] 1. When the filter holes are clogged, water accumulates between the rain cover and the guide ring and continues to increase, causing the guide ring to move downward. Then, the drive component drives the support shaft to rotate, and the power component drives the connecting arm to flip upward, which helps the cleaning brush to clean and unclog the corresponding filter holes.

[0058] 2. When the plug disengages from the plug slot, the shaft enters a rotating state, causing the coil spring to release instantly, increasing the rotation speed of the support shaft, improving the cleaning effect of the cleaning brush bristles, and reducing the possibility of rainwater entering the rainwater tank when a small number of filter holes are blocked, thus causing the guide ring to slide out of the installation slot.

[0068] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0069] This application discloses a roof water supply and drainage system. See also... Figure 1 The roof water supply and drainage system includes a mounting base 1, which is embedded and fixed on the roof.

[0070] See Figure 2 and Figure 3 The roof drainage system also includes a rainwater pipe 2 and a rainwater cover 3. The rainwater pipe 2 is fixed inside the mounting base 1 and extends downwards along the building to a position close to the ground. It is then connected to ground manholes and inspection wells via pipes, allowing rainwater in the rainwater pipe 2 to be discharged into the underground stormwater and sewage system. A receiving groove 11 is formed on the top of the mounting base 1, and the pipe opening of the rainwater pipe 2 is located on the bottom wall of the receiving groove 11. The rainwater cover 3 is a cylindrical structure. A rainwater trough 32 is formed inside the rainwater cover 3. The rainwater cover 3 is coaxially arranged with the rainwater pipe 2 and fixed to the top of the rainwater pipe 2. Multiple filter holes 31 are evenly opened on the rainwater cover 3. The filter holes 31 are connected to the rainwater trough 32. Rainwater from the roof is filtered through the filter holes 31 and enters the rainwater cover 3 before flowing into the rainwater pipe 2 and being discharged. When the roof is equipped with structures such as gutters or eaves gutters, the mounting base 1 is preferably set inside the gutters or eaves gutters to facilitate rainwater collection and flow towards the mounting base 1.

[0071] The roof drainage system also includes a connecting shaft 4 and a supporting shaft 41. The connecting shaft 4 is rotatably connected to the rain cover 3 and located inside the rain gutter 32. The connecting shaft 4 and the rain cover 3 are coaxially arranged. The supporting shaft 41 is rotatably connected to the bottom of the connecting shaft 4. The supporting shaft 41 and the connecting shaft 4 are coaxially arranged and located inside the rain gutter 32.

[0072] The roof drainage system also includes a connecting arm 42, a cleaning brush 43, and cleaning bristles 44. The connecting arm 42 is hinged to the outer periphery of the support shaft 41 and can be rotated up and down. There can be one or more connecting arms 42; in this embodiment, there are two. The cleaning brush 43 has an arc-shaped plate structure. A hinge shaft is rotatably connected to the end of the connecting arm 42 away from the support shaft 41, and one end of the cleaning brush 43 is hinged to the hinge shaft. When the connecting arm 42 is rotated downwards to a vertical position, the arc-shaped concave side of the cleaning brush 43 faces the support column, and multiple cleaning bristles 44 are evenly spaced and fixed on the side of the cleaning brush 43 away from the support shaft 41.

[0073] A torsion spring 421 is fitted over the hinge shaft. One end of the torsion spring 421 abuts against the cleaning brush 43, and the other end abuts against the connecting arm 42. When the torsion spring 421 is released elastically, it drives the connecting arm 42 to rotate away from the support shaft 41. A limiting block 422 is fixedly connected to the side of the connecting arm 42 away from the support shaft 41. When the torsion spring 421 drives the cleaning brush 43 to rotate until it is in a straight line with the connecting arm 42, the limiting block 422 prevents the cleaning brush 43 from continuing to rotate away from the support shaft 41.

[0074] The roof water supply and drainage system also includes a power component, which drives the connecting arm 42 to rotate up and down when the support shaft 41 rotates.

[0075] The power assembly includes a power sleeve 9, a power column 91, and a power bar 92. The power sleeve 9 is fitted onto the outer periphery of the connecting shaft 4 and is threadedly connected to the connecting shaft 4. The power bar 92 has a cuboid structure and is fixed to the outer periphery of the power sleeve 9. The length direction of the power bar 92 is perpendicular to the central axis of the connecting shaft 4. The power bar 92 has an oblong hole 921 along its length direction. The power column 91 slides up and down in the oblong hole 921 and can slide along the length direction of the power bar 92 in the oblong hole 921. A limit block 911 is fixed to the top of the power column 91 to prevent the power column 91 from sliding downward and disengaging from the oblong hole 921. The bottom of the power column 91 is hinged to the connecting arm 42.

[0076] When the support shaft 41 rotates forward and drives the connecting arm 42 to rotate accordingly, the connecting arm 42 drives the power sleeve 9 to rotate via the power column 91. At this time, the power sleeve 9 slides up and down on the connecting shaft 4. When the power sleeve 9 slides upward, the power column 91 drives the connecting arm 42 to flip upward. During the flipping process, the cleaning brush 43 first slides on the inner wall of the rainwater pipe 2, and under the action of the inner wall of the rainwater pipe 2, the cleaning brush 43 and the connecting arm 42 flip, causing the angle between the connecting arm 42 and the cleaning brush 43 to gradually decrease until the connecting arm 42 flips upward to a horizontal state, at which point the angle between the connecting arm 42 and the cleaning brush 43 is close to ninety degrees. At this time, the bristles of the cleaning brush 43 pass through the water filter hole 31 to the outside of the rainwater cover 3. During the movement of the cleaning brush 43 following the connecting arm 42, the cleaning brush 43 cleans the rainwater cover 3 through the cleaning bristles 44, unblocks the water filter hole 31, and reduces clogging.

[0077] When the support shaft 41 rotates in the opposite direction and drives the connecting arm 42 to rotate accordingly, the power sleeve 9 slides downward on the connecting shaft 4, and the power column 91 drives the connecting arm 42 to flip downward. Under the drive of the torsion spring 421, the angle between the cleaning brush 43 and the connecting arm 42 gradually increases until they are in the same straight line.

[0078] The roof drainage system also includes a guide ring 5, which surrounds the rain cover 3 and is located within the receiving groove 11. The top end face of the guide ring 5 is on the same plane as the top end face of the mounting base 1, and the vertical sidewalls of the guide ring 5 slide in contact with the groove wall of the receiving groove 11. The guide ring 5 is inclined downward towards the rain cover 3 to form a guiding surface. Rainwater on the mounting base 1 flows towards the rain cover 3 through the guiding surface, which helps to accelerate the flow speed of rainwater towards the rain cover 3. At the same time, the impact force generated by the rainwater flow impacts the filter holes 31 of the rain cover 3, reducing the possibility of clogging of the filter holes 31.

[0079] Mounting base 1 has a mounting groove 12, which is located directly below and connected to receiving groove 11. Guide ring 5 slides up and down in mounting groove 12. The roof drainage system also includes an elastic drive component, which is a drive spring 51. Drive spring 51 is installed in mounting groove 12, with its top abutting against the bottom of guide ring 5 and its bottom abutting against the bottom wall of mounting groove 12. When drive spring 51 is released elastically, it drives guide ring 5 to move upward and disengage from mounting groove 12. When the filter hole 31 of rain cover 3 is blocked, rainwater begins to accumulate between the guide surface and rain cover 3, and the water level gradually rises. Guide ring 5, under the influence of gravity generated by the increasing rainwater, begins to slide downward into mounting groove 12, at which point drive spring 51 begins to compress.

[0080] See Figure 3 and Figure 4The roof water supply and drainage system also includes a drive component, which is installed on the mounting base 1. When the guide ring 5 slides down into the mounting groove 12, the drive component drives the support shaft 41 to enter the forward rotation state.

[0081] See Figure 3 and Figure 5 The drive assembly includes a drive gear 6, a drive rack 61, a drive shaft 62, a transmission helical gear 63, a transmission shaft 64, a connecting helical gear 65, and a drive belt 66.

[0082] A drive groove 13 is formed within the mounting base 1. A drive shaft 62 is rotatably connected to the mounting base 1 and located within the drive groove 13. A drive gear 6 is fixed to the outer periphery of the drive shaft 62 and located within the drive groove 13. A drive rack 61 is fixed to the outer periphery of the guide ring 5. The mounting base 1 has a vertically extending movable hole 14 that communicates with the drive groove 13. The drive rack 61 slides up and down within the movable hole 14 and protrudes into the drive groove 13, meshing with the drive gear 6. A transmission shaft 64 is rotatably connected to the mounting base 1 and located within the drive groove 13. The transmission shaft 64 is parallel to the support shaft 41 and perpendicular to the drive shaft 62. A transmission helical gear 63 is fixed to the outer periphery of the transmission shaft 64 and located within the drive groove 13. A connecting helical gear 65 is fixed to the outer periphery of the drive shaft 62 and located within the drive groove 13, meshing with the transmission helical gear 63.

[0083] The drive belt 66 is connected end to end and sleeved between the drive shaft 64 and the support shaft 41. The drive belt 66 slides through the mounting base 1 and the rainwater pipe 2 respectively. When the guide ring 5 slides down into the mounting groove 12, the drive rack 61 drives the drive shaft 62 to rotate through the drive gear 6. Then, the connecting helical gear 65 drives the drive shaft 64 to rotate through the transmission helical gear 63. At this time, the drive shaft 64, through the drive belt 66, links the support shaft 41, causing the support shaft 41 to enter a forward rotation state. Correspondingly, when the guide ring 5 slides up out of the mounting groove 12, the drive shaft 64, through the drive belt 66, drives the support shaft 41 to enter a reverse rotation state.

[0084] To increase the rotational speed of the support shaft 41 and improve the cleaning effect of the cleaning bristles 44, the drive shaft 64 includes a bushing 641, a shaft body 642, and a coil spring 643. The shaft body 642 is rotatably connected to the mounting base 1, and the drive belt 66 is sleeved between the shaft body 642 and the support shaft 41. The bushing 641 is rotatably connected to the mounting base 1 and sleeved on the outer periphery of the shaft body 642. The inner diameter of the bushing 641 is larger than the outer diameter of the shaft body 642, and the transmission helical gear 63 is fixed on the outer periphery of the bushing 641. The coil spring 643 is sleeved on the outer periphery of the shaft body 642 and located between the shaft body 642 and the bushing 641. One end of the coil spring 643 is engaged with the shaft body 642, and the other end is engaged with the inner wall of the bushing 641.

[0085] A sliding groove 76 is formed within the mounting base 1, communicating with the drive groove 13. The shaft 642 protrudes into the sliding groove 76. The mounting base 1 is provided with a plug-in post 7, which slides in the sliding groove 76 and protrudes into the drive groove 13. A plug-in groove 644 is formed on the outer periphery of the shaft 642, and the plug-in post 7 is inserted into the plug-in groove 644, causing the shaft 642 to enter a stationary state.

[0086] Mounting base 1 is equipped with a control component. The control component controls the insertion post 7 to insert into or disengage from the insertion slot 644, locks the shaft 642, and controls the shaft 642 to enter the rotation state. This allows the coil spring 643 to release its accumulated elasticity instantly, improving the cleaning effect of the rain cover 3 and reducing the possibility of rainwater entering the rainwater trough 32 when a small number of filter holes 31 are blocked, thereby causing the guide ring 5 to slide out of the mounting slot 12.

[0087] See Figure 6 and Figure 7 The control components include a control block 81, a control column 8, and a push block 82.

[0088] See Figure 5 and Figure 7 The control post 8 is fixed to the drive rack 61 near the insertion post 7, and the control block 81 is fixed to the control post 8, forming a "7" shape. A control groove 74 is formed on the outer periphery of the insertion post 7, and the portion of the control groove 74 is located within the drive groove 13. The push block 82 slides up and down in the control groove 74, and the insertion post 7 is inclined to form a push surface 75, which is located within the control groove 74. When the guide ring 5 moves downwards until the drive rack 61 is close to the bottom wall of the drive groove 13, the push block 82 slides down into the control groove 74. At this time, the push block 82 slides on the push surface 75, pushing the insertion post 7 out of the insertion groove 644, and the shaft 642 enters a rotatable state.

[0089] The control block 81 is fixed to the side wall of the drive rack 61 near the insertion post 7, and is located directly below the control post 8. A control surface 811 is formed on the control block 81 at an angle, making it a right-angled trapezoid with the inclined surface of the trapezoid at the top. When the guide ring 5 slides upwards to the bottom groove wall of the drive rack 61 near the insertion post 7, the insertion post 7 slides on the control surface 811. At this time, the control block 81 pushes the insertion post 7 to slide towards the insertion groove 644. When the insertion post 7 is aligned with the insertion groove 644, and the insertion post 7 slides from the control surface 811 to the side wall of the control block 81 away from the drive rack 61, the insertion post 7 inserts into the insertion groove 644, at which point the shaft 642 is restricted from rotation.

[0090] See Figure 8The insertion post 7 includes an inner post 71, an outer post 72, and a connecting spring 73. The outer post 72 has an "L"-shaped structure, and the control groove 74 is located on the outer post 72. The inner post 71 slides on the outer post 72, and the inner post 71 is located close to the insertion groove 644 (the insertion groove 644 is in...). Figure 5 (Pointed out) One side. The connecting spring 73 is installed inside the outer column 72. One end of the connecting spring 73 is fixed to the inner column 71, and the other end is fixed to the outer column 72. When the connecting spring 73 is released elastically, it pushes the inner column 71 to slide out of the outer column 72.

[0091] See Figure 5 and Figure 7 When the pusher block 82 pushes the outer post 72 away from the insertion slot 644, the connecting spring 73 pulls the inner post 71 away from the insertion slot 644. When the inner post 71 is not aligned with the insertion slot 644, the control block 81 pushes the outer post 72 to slide towards the insertion slot 644. At this time, the connecting spring 73 transmits power, causing the inner post 71 to abut against the outer circumference of the shaft 642. At this time, the connecting spring 73 is in a compressed state. Then, the drive rack 61 continues to move upward. When the outer post 72 slides on the side wall of the control block 81 away from the drive rack 61, the shaft 642 continues to rotate until the insertion slot 644 and the inner post 71 are aligned. Then, the connecting spring 73 pushes the inner post 71 into the insertion slot 644.

[0092] The implementation principle of a roof water supply and drainage system according to an embodiment of this application is as follows:

[0093] When the filter hole 31 is blocked, water accumulates between the guide ring 5 and the rain cover 3 and the water level gradually rises. At this time, the guide ring 5 begins to move downward and the coil spring 643 enters the elastic storage state. Until the push block 82 pushes the plug pin 7 out of the plug slot 644, the shaft 642 enters the rotation state, driving the belt 66 to link the support shaft 41, so that the connecting arm 42 rotates and flips upward at the same time. At this time, the cleaning brush 43 follows the movement of the connecting arm 42 and cleans the rain cover 3 when it is blocked, which helps to unclog the filter hole 31.

[0094] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
