Description

Technical Field

[0001] The present application relates to the field of construction engineering technology, and in particular to a new drainage structure for the roof of an existing building. Background Art

[0002] At present, in the process of construction, especially when renovating some old houses, water often accumulates on the roof due to unreasonable original design or disrepair, which not only affects the appearance of the building, but more seriously, long-term water accumulation will cause leakage and even damage the safety hazard of the load-bearing structure. Although various waterproof materials and technical means have appeared on the market to improve this situation, their application scope is limited by factors such as the complex structure of old buildings and high maintenance costs.

[0003] Generally speaking, the traditional methods of dealing with such problems in the existing technology mainly include but are not limited to increasing the roof slope, adding water collection wells and sewer pipe systems, etc. Among them, although increasing the roof slope can promote the flow of rainwater and reduce the generation of water accumulation to a certain extent, it is difficult to implement for an already built flat-roof structure and may change the original architectural style; another common method is to achieve active drainage by adding water collection wells to connect sewer pipes, but this method often requires excavating the ground to lay new pipelines, which is a cumbersome process and easily damages the surrounding environment.

[0004] In addition, the above traditional solutions generally have problems such as large engineering workload and long renovation period, which means higher economic burden and inconvenient living experience for the owners. In addition, measures such as increasing the roof slope also face the challenge of how to balance aesthetics and functionality, and in actual operation it is difficult to completely avoid interference with surrounding facilities.

[0005] Regarding the above-mentioned related technologies, this technology mainly solves the following technical problems: how to effectively improve the drainage performance of the roof area of ​​old residential areas without significantly changing the original building design, reduce subsequent maintenance costs while ensuring that the normal living of residents is not affected.

The diversion trough is set at the edge of the roof, which successfully avoids excessive interference to the daily life of residents due to renovation activities. Then the rate is adjusted by the regulator until the ideal discharge state is reached; during this period, the quick connector ensures that the various components are closely connected to prevent water leakage; finally, the collected precipitation flows into the preset water collection tank for storage and standby. As a sealed water storage structure, the water collection tank can effectively store the rainwater flowing down the drainage pipe. Water has promoted the secondary development and utilization of urban rainwater resources, and in this way has greatly simplified the construction process and reduced the overall cost expenditure; a connecting rod is arranged around the center of the water pipe to support the swirl fan, and the swirl fan is set in the center of the water pipe.

The two-way switch is connected to the power supply and the drive motor. The wheel can be manually rotated to control the displacement baffle. The design of the wheel allows the user to adjust the position of the displacement baffle through simple manual operation, which is convenient and quick. At the same time, the addition of the two-way switch allows the entire system to operate automatically through the power supply, improving work efficiency and safety. Regardless of manual or automatic mode, the system can quickly respond to user operations and achieve precise control of water flow. The movement of the displacement baffle is precisely guided by the rack and guide rail to ensure precise adjustment of the size of the water flow channel. A protective door is provided on one side of the wheel and the two-way switch. Closing the protective door when not in use and after adjustment is completed can prevent dust from accumulating inside the control box and affecting the operation of the device.

[0015] Preferably, an inverter is provided on one side of the power supply, and the power supply is connected to the solar panel via the inverter.

After reaching the designated position, the spring resets and pushes the displacement plate to displace, so that the protruding block is stuck in the corresponding connection point of the quick connector.

[0018] By adopting the above technical solution, the quick connector is welded and fastened with the regulator above after leaving enough connection space, and then the connection structure of the drain pipe is connected to the quick connector as a whole through the connecting plug. The connecting flange of the drain pipe is tightened and positioned by extending and rotating the connecting plug, so that water can pass stably. The core design of the quick connector is that it can achieve rapid and reliable connection. The displacement plate moves under the push of the connecting plug and compresses the spring adjacent to it at the same time. This design utilizes the elastic potential energy of the spring to provide power for the subsequent locking mechanism. This design makes the connection process of pipes or equipment simple and quick, greatly shortens the installation time, and ensures the stability and reliability of the connection through the cooperation of the spring and the protrusion block, and it is not easy to fall off even in the case of vibration or pressure changes.

At the same time, its good waterproof performance effectively prevents groundwater infiltration, protects the structural strength of the water collecting tank and prevents groundwater from eroding the water collecting tank. The main function of the filling layer is to provide The thermal insulation effect reduces the impact of external temperature changes on the water temperature in the water collecting tank. At the same time, it can also buffer external shocks and enhance the overall stability of the structure to a certain extent, thereby improving the waterproof performance of the water collecting tank and ensuring that leakage problems are unlikely to occur during long-term use. The overflow port passes through the No. 1 cement layer through the sewer pipe to ensure that the water can be automatically drained when the water collecting tank is full to prevent overflow. The exhaust pipe extends out of the top of the No. 2 cement layer and is provided with a dust cover, which can not only discharge the gas in the water collecting tank and maintain the balance of internal and external air pressure, but also effectively prevent dust and debris from entering to ensure clean water quality.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1 -Attached Fig.10 , further details of this application are given.

[0027] The embodiment of the present application discloses a new drainage structure for the roof of an existing building.

[0028] Reference Figure 1 and Figure 2 A new drainage structure for the roof of an existing building includes a guide trough 1, a regulator 2, a quick connector 3 and a water collecting tank 4. The guide trough 1 is recommended to be made of stainless steel, which has good corrosion resistance and compressive strength, and both sides of the interior of the guide trough 1 are set as curved surfaces. This design utilizes the boundary layer theory in fluid mechanics. The curved surface can guide the water to pass smoothly and reduce turbulence and energy loss caused by a sharp change in the direction of the water flow. The quick connector 3 and the water collecting tank 4, the former are generally made of PE plastic, and the latter are more common in reinforced concrete casting, which can ensure sufficient sealing effect and meet daily maintenance needs. The regulator 2 adopts an electronic induction control system to achieve a higher degree of automation in the regulation process, and can also be manually controlled, so that the structure can more flexibly adapt to the needs of different seasonal changes.

[0029] During use, the guide trough 1 is set at the edge of the roof to guide rainwater to the predetermined collection point; the regulator 2 is installed at the end of the guide trough 1, and the water flow rate can be adjusted according to the actual precipitation; the quick connector 3 is located at the outlet of the regulator 2, which is convenient for later maintenance and replacement of parts without having to dismantle the entire device; finally, the water collection tank 4 is buried underground, responsible for storing rainwater resources after preliminary filtration for recycling. This design constitutes a rainwater collection structure from the roof to the underground, preventing rainwater from accumulating on the roof.

[0030] Reference Figure 2 and Figure 3, a filter plate 5 is arranged on the top of the guide trough 1. The filter plate 5 is made of stainless steel to withstand the pressure of water flow impact and impurity clogging. The filter plate 5 is composed of a plurality of parallel inclined plates to form a plate-like structure. A plurality of parallel inclined plates are arranged to form a plurality of narrow channels at the top. The filter plate 5 adopts a parallel inclined plate structure design. Impurities follow the water flow and move to the filter plate 5. The water enters the guide trough 1 below through the filter plate 5. Impurities remain on the filter plate 5. Because the guide trough 1 is arranged on the roof, the impurity type is single and the amount is small, and the maintenance cycle is long. The parallel inclined plate structure enables the filter plate 5 to not damage the water during long-term use. The passage of the body is affected, and the possibility of impurities blocking the filter plate 5 is prevented. A water pipe 6 is arranged on one side of the guide groove 1. The water pipe 6 is arranged in several groups, and each group of water pipes 6 is evenly arranged along the horizontal direction of the guide groove 1. The water pipe 6 and the guide groove 1 form a connecting structure, so that the water body can directly enter the water pipe 6 after entering the guide groove 1. The water pipe 6 is also made of stainless steel. Its main function is to guide the water flow to a specific position or area to ensure the uniform distribution and effective utilization of the water flow. The uniform arrangement of multiple groups of water pipes 6 can optimize the water flow path, reduce energy loss, and improve the fluid transportation efficiency.

[0031] During use, the filter plate 5 is assembled in advance, and then after checking the permeability of the water body, the filter plate 5 is installed on the top of the guide groove 1 through the slot above the guide groove 1 to prevent impurities from entering the guide groove 1 and causing blockage. The water pipe 6 is connected to the connecting hole on the side of the guide groove 1 by welding. Sealant should be set at the connection to prevent water leakage. After the installation is completed, water should be poured to check whether the water can pass through the guide groove 1 into the water pipe 6.

[0032] Reference Figure 2 A guide pipe 7 is provided at the bottom of the water guide pipe 6, one side of the guide pipe 7 is connected to the regulator 2, and a thread 15 is provided on one side of the guide pipe 7. The guide pipe 7 is connected to the regulator 2 through the thread 15. The guide pipe 7 is made of stainless steel. The main function of the guide pipe 7 is to connect the guide groove 1 and the regulator 2 to ensure that rainwater can flow smoothly from the guide groove 1 to the regulator 2 for subsequent treatment.

[0033] During use, each group of water pipes 6 is welded to the connecting holes on the outer wall of the guide pipe 7 in turn. The water pipes 6 and the guide pipes 7 form a connecting structure so that water can smoothly enter the guide pipes 7. Then sealant is also set at the connection to prevent water leakage. The other side of the guide pipe 7 is connected to the regulator 2 through the thread 15 to ensure that the connection is tight. The guide pipe 7 allows the water to be effectively transported to the regulator 2 through the guide pipe 7, and then the water flow rate is adjusted through the regulator 2 to achieve an ideal discharge state.

[0034] Reference Figure 6 and Figure 7The regulator 2 includes a shell 16, a water pipe 17 and a guide rail 18. The shell 16 can be made of stainless steel. Stainless steel has excellent corrosion resistance and compressive strength. The main function of the shell 16 is to protect the internal components from the influence of the external environment, prevent dust, debris, etc. from entering the interior, and keep the interior clean. The water pipe 17 uses stainless steel material and can be used in outdoor environments for a long time without being corroded or damaged. The main function of the water pipe 17 is to transport rainwater. The guidance of the water pipe 17 ensures that rainwater will not leak or be blocked during the transportation process. The main function of the guide rail 18 is to guide the displacement baffle 20 to move smoothly along a specific path. Through the guidance of the guide rail 18, the displacement baffle 20 can accurately control the speed and flow of the water flow, thereby meeting the drainage needs under different rainfall conditions.

[0035] During use, one side of the water pipe 17 extends out of the outer shell 16 as a water inlet, and the water inlet on one side of the water pipe 17 is connected to the guide pipe 7 through a thread 15, so that water can flow into the water pipe 17. The guide rail 18 at the bottom of the water pipe 17 is adjacent to the water pipe 17, ensuring that the displacement baffle 20 will not deviate from the direction or get stuck during the movement.

[0036] Reference Figure 6 , Figure 7 and Fig. 9 A swirl fan 19 is arranged at the inner center of the water pipe 17. The main function of the swirl fan 19 is to generate a rotating flow and increase the drainage efficiency. When rainwater passes through the water pipe, the swirl fan 19 will cause the rainwater to generate a rotating flow while the water enters the water pipe 17. This can reduce the resistance of rainwater in the water pipe and increase the drainage speed. At the same time, the rotating flow can also prevent debris from depositing in the water pipe and keep the water pipe unobstructed.

[0037] During use, the swirl fan 19 is arranged at the inner center of the water pipe 17 and is connected to the inner wall of the water pipe 17 by a connecting rod. The connecting rod is connected to the fixed shell of the swirl fan 19. The swirl fan 19 is provided with a fixed shell on the outer side of the fan body rotating shaft for connecting with the water pipe 17 and extending the service life of the rotating shaft of the swirl fan 19. The water flow entering the water pipe 17 will give the swirl fan 19 a rotational force, so that the rotating shaft of the swirl fan 19 starts to rotate along its own fixed shell under the drive of the water flow.

[0038] Reference Figure 6 , Figure 7 and Fig.10A displacement baffle 20 is arranged on the contact surface between the water pipe 17 and the guide rail 18, a rack 21 is arranged on one side of the displacement baffle 20, and a driving gear 22 is arranged on one side of the rack 21. The displacement baffle 20 can be made of stainless steel. The main function of the displacement baffle 20 is to adjust the speed and flow of the water flow. By moving the displacement baffle 20, the size of the water flow outlet of the water pipe 17 can be changed, thereby controlling the speed and flow of the water flow to adapt to the water flow in different seasons. The main function of the rack 21 is to transmit power and convert the rotational motion of the driving gear 22 into the horizontal movement of the displacement baffle 20. Through the meshing of the rack 21 and the driving gear 22, the power can be accurately transmitted to the displacement baffle 20, so that it moves smoothly along the guide rail 18. The main function of the driving gear 22 is to transmit power and convert the command of the control box 23 into the horizontal movement of the displacement baffle 20.

[0039] During use, the displacement baffle 20 is set on the guide rail 18 and connected to the rack 21. The other side of the rack 21 is combined with the driving gear 22. The driving motor 39 drives the gear set 41 to rotate, so that the driving gear 22 drives the rack 21 to move, pushing the displacement baffle 20 to move horizontally along the guide rail 18. This design can accurately control the water flow speed and facilitate external operation and maintenance, so that the device can more flexibly adapt to the needs of different seasonal changes.

[0040] Reference Figure 6 and Figure 7 A control box 23 is provided on one side of the driving gear 22, a pressure sensor 24 is provided on one side of the control box 23, and a power supply 25 is provided above the control box 23. The main function of the control box 23 is to receive the pressure sensor 24 and control the rotation of the driving gear 22. The model of the pressure sensor 24 is YWK-100, which can accurately measure and display the pressure value of the water flow. The pressure sensor 24 controls the displacement distance of the displacement baffle 20 by monitoring the water flow pressure passing through the regulator 2 on the inner wall of the water pipe 17, thereby automatically changing the speed and flow of the water flow. The main function of the power supply 25 is to provide power support for the control box, pressure sensor and other components. The power supply 25 is made of lithium batteries and can be charged by solar panels 8.

[0041] During use, the control box 23 is set on one side of the regulator 2 to facilitate user operation. When the user needs to adjust the water flow rate, he only needs to input the corresponding instructions on the control box 23, and the control box 23 will automatically control the rotation of the driving gear 22 to adjust the water flow rate. The pressure sensor 24 is inserted into the inner wall of the water pipe 17 and fixed so that it can monitor the pressure of the water flow. The power supply 25 is set inside the outer casing 16 by bolts to keep it stable.

[0042] Reference Figure 6 and Fig.10A protective door 26 is provided on one side of the control box 23, a rotating wheel 27 is provided on one side of the protective door 26, and a two-way switch 28 is provided above the rotating wheel 27. The protective door 26 is made of the same material as the outer shell 16, which can prevent dust, debris, etc. from entering the interior and keep the interior clean. The rotating wheel 27 is provided on one side of the control box 23. The rotating wheel 27 is manually rotated, and the rotating wheel 27 drives the gear set 41 to move, thereby driving the driving gear 22 to rotate to displace the rack 21, so that the manually driven displacement baffle 20 is displaced, and there is a rotating shaft between the rotating wheel 27 and the gear set 41. The two-way switch 28 can control the connection between the power supply 25 and the control box 23. When the power supply 25 is turned on to drive the driving motor 39 to rotate the driving gear 22, the rotating wheel 27 can be stationary, so that the regulator 2 can be rotated manually or electrically adjusted, providing a more personalized way.

[0043] During use, one side of the control box 23 is provided with a fixed slot on the outer shell 16, and one side of the slot is connected to a protective door 26. A rotating wheel 27 and a two-way switch 28 are provided on the inner side of the protective door 26. The protective door 26 can be opened so that the staff can operate the rotating wheel 27 and the two-way switch 28.

[0044] Reference Figure 1 and Figure 6 A solar panel 8 is arranged on the top of the regulator 2, and an inverter 29 is arranged on one side of the power supply 25. The power supply 25 is connected to the solar panel 8 through the inverter 29. The solar panel 8 is installed on the top of the regulator 2, facing the direction of sunlight, so as to ensure that the solar panel 8 can receive sunlight to the maximum extent and improve the energy conversion efficiency. The solar panel 8 is connected to the power supply 25 through the inverter 29. The inverter 29 converts the direct current generated by the solar panel 8 into alternating current, which is supplied to the control box 23 and other components. The model of the inverter 29 can be an MPPT solar controller, which has high conversion efficiency and stability, can adapt to different lighting conditions, and ensure the effective power output of the solar panel 8.

[0058] The implementation principle of the embodiment of the present application is as follows: when rainfall occurs, rainwater is first guided by the guide groove 1 and flows along a set path to the regulator 2. The guide groove 1 is arranged at the edge of the roof to guide rainwater to the predetermined regulator 2 to ensure that rainwater can smoothly enter the sewer pipe 11. The regulator 2 can adjust the water flow rate according to the actual precipitation to ensure that the water flow is stable and will not overflow due to heavy rain. A quick connector 3 is provided at the outlet of the regulator 2 to facilitate later maintenance and replacement of parts without having to dismantle the entire device. The rainwater eventually flows into the underground water collecting tank 4 for storage and standby. In order to ensure the internal air pressure balance of the system, an exhaust pipe 13 is provided on the top of the water collecting tank 4 to discharge excess gas. At the same time, when the water level inside the water collecting tank 4 exceeds the safety value, the overflow port 14 will automatically discharge excess rainwater to prevent problems caused by excessive water accumulation.
