Description

Technical Field

[0001] This invention relates to the field of drainage device technology, and more specifically, to a high-flow-rate drainage device and drainage system. Background Technology

[0002] In building drainage systems, roof or floor drainage is a crucial aspect of ensuring the functional integrity and lifespan of a building. Traditional drainage methods primarily rely on gravity to allow water to flow naturally into the drainage pipe system. However, with increasing building height and rising drainage demands, the design of drainage systems has become more complex.

[0003] Because drainage pipes typically contain air, when water from the roof or floor enters the pipes through the drain outlet, the air inside the pipes obstructs the smooth flow of water. This is especially true when the water flow is high; the accumulation of air significantly reduces the water flow velocity, preventing the air from being expelled in time, thus creating airlock. Airlock not only slows down drainage but can also cause water accumulation and backflow, further exacerbating drainage problems and affecting the normal use of the building.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0013] And / or, the connector is fitted onto the surface of the guide.

[0014] In an optional embodiment, the high-flow-rate drainage unit further includes bearings located at both ends of the shoulder in the axial direction, and both the bearings and the shoulder are accommodated within the second limiting portion.

[0019] And / or, the guide component has a trumpet-shaped structure, with the large-diameter end fixedly connected to the inner wall of the main body, and the small-diameter end spirally connected to the rotating power component on one side.

[0020] And / or, a second limiting platform is also provided in the first installation section of the main body, and the guide component is fixed to the main body through the second limiting platform.

[0025] Secondly, the present invention provides a drainage system, including a drainage pipe and a drainage device as described in any of the foregoing embodiments, wherein the drainage pipe is fixedly connected to a second mounting section of the main body.

[0026] The present invention has the following beneficial effects: This invention provides a high-flow-rate drainage device and system. The main body has an axially continuous internal channel, forming a continuous water flow path. A mounting base is fixed inside the main body and serves to support and position the high-flow-rate drainage unit. The high-flow-rate drainage unit is driven to rotate by the water flow through a rotating power component, thereby causing the entire rotating shaft to rotate around its own axis. The first section of the rotating shaft has a guide groove extending along the axial surface and having a continuously changing trajectory. This allows the movable component housed within the guide groove to generate periodic axial reciprocating motion under its guidance when the rotating shaft rotates. One end of the movable component is located within the guide groove to receive motion conversion, while the other end protrudes from the guide groove and is fixedly connected to a connecting component. The connecting component is further fixedly connected to the high-flow-rate drainage component, thereby transmitting the reciprocating linear motion of the movable component to the high-flow-rate drainage component, enabling it to synchronously perform axial extension and contraction. The relative position between the high-flow-rate drainage component and the drainage panel continuously changes, forming a dynamic ventilation gap. Even when the drainage panel is submerged by water, this dynamic gap allows for timely discharge of gas from the pipe, avoiding drainage problems caused by air resistance. The device utilizes the water flow's own energy to drive mechanical movement, requiring no external power source. It is reliable in operation and has low maintenance costs, making it particularly suitable for gravity flow drainage scenarios such as roofs or floors. Even under high-flow drainage conditions, it can maintain good venting performance and drainage capacity, thus effectively solving the problem of reduced water flow velocity caused by air accumulation in traditional drainage systems.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0031] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0032] First Embodiment Please refer to Figures 1-3 This embodiment provides a high-flow-rate drainage device 100, including a main body 110, a mounting base 120, a drainage panel 130, and a high-flow-rate drainage unit 140.

[0033] Please refer to Figure 4 The interior of the main body 110 is axially continuous, forming a continuous water flow channel. The two ends of the main body 110 extending axially are the first installation section 111 and the second installation section 112, respectively.

[0034] A third limiting platform 1112 is provided in the first installation section 111 of the main body 110, and the drainage panel 130 is limited and fixed in the first installation section 111 by the third limiting platform 1112. The first installation section 111 serves as the water inlet end face, used to guide external water flow into the interior of the main body 110.

[0035] A fourth limiting platform 1121 is provided in the second installation section 112 of the main body 110, and the mounting base 120 is limited and fixed in the second installation section 112 by the fourth limiting platform 1121. The second installation section 112 serves to support and position the high-flow drainage unit 140, and ensure the stable installation of the high-flow drainage unit 140 in the main body 110.

[0036] Please refer to Figure 5 In this embodiment, the mounting base 120 includes a first limiting part 121, a second limiting part 122, and a connecting part 123. The first limiting part 121 is fixed to the second mounting section 112 of the main body 110 by a fourth limiting platform 1121, thereby achieving a stable connection between the mounting base 120 and the main body 110. The second limiting part 122 is located inside the first limiting part 121 and is spaced apart from it. The two are connected into an integral structure by the connecting part 123. At the same time, the connecting part 123 divides the annular gap between the first limiting part 121 and the second limiting part 122 into multiple water flow channels.

[0037] In this embodiment, there are three connecting parts 123, therefore, the number of water flow channels divided by the connecting parts 123 is also three. In other embodiments, the number of connecting parts 123 can be two, or it can be increased to four, five or even more, as long as it can connect and stably support the high-flow drainage unit 140.

[0038] By setting the mounting base 120, not only is the high-flow-rate drainage unit 140 stably installed within the main body 110, but it also ensures that water flowing through the area of ​​the mounting base 120 can smoothly enter the downstream interior of the main body 110 through multiple diversion channels. This avoids the problem of increased water flow resistance caused by sudden changes or blockages in local cross-sections, thus ensuring drainage efficiency under high-flow-rate conditions. In addition, the presence of multiple water flow channels also plays a role in uniformly guiding the flow, helping to reduce eddies or pressure fluctuations generated when the water flows through the mounting base 120, improving drainage stability, which in turn facilitates the stable rotation of the rotating power component 142, thereby ensuring the stable axial movement of the high-flow-rate drainage component 145.

[0039] Please see Figure 2 and Figure 3 The high-flow drainage unit 140 is housed inside the main body 110 via the mounting base 120, forming the core of the drive and execution for high-flow rapid drainage. In this embodiment, the high-flow drainage unit 140 includes a rotating shaft 141, a rotating power component 142, a connecting component 143, a movable component 144, a guide component 146, and a high-flow drainage component 145.

[0040] Please see Figure 6 and Figure 7 The rotating shaft 141 includes a first shaft segment 1411, a shoulder 1412, and a second shaft segment 1413 arranged sequentially along the direction from the first mounting segment 111 to the second mounting segment 112. The shoulder 1412 protrudes from the first shaft segment 1411 and the second shaft segment 1413 and is fixed in the second limiting part 122 of the mounting base 120, thereby realizing the rotatable support of the rotating shaft 141 within the main body 110.

[0041] Please see Figure 5 and Figure 6 In this embodiment, a first limiting platform 1221 is provided within the second limiting portion 122 of the mounting base 120. The shoulder 1412 is accommodated within the second limiting portion 122 and limited by the first limiting platform 1221. The second shaft segment 1413 passes through the first limiting platform 1221 and is fixedly connected to the rotating power member 142 at the end away from the shoulder 1412. By providing the first limiting platform 1221, the rotating shaft 141 is reliably limited in the axial direction within the second limiting portion 122, preventing axial movement during operation.

[0042] Please see Figure 2 and Figure 3 In this embodiment, the high-flow-rate drainage unit 140 also includes bearings 147, which are located at both ends of the axial direction of the shoulder 1412, and both the bearings 147 and the shoulder 1412 are accommodated within the second limiting portion 122. This embodiment utilizes the bearings 147 to achieve a low-friction rotational fit between the rotating shaft 141 and the mounting base 120, significantly reducing mechanical resistance and wear during rotation, and improving the service life and operating efficiency of the device. The two bearings 147 are respectively arranged on both sides of the shoulder 1412, forming a symmetrical support structure, which can effectively distribute the radial load and torque stress from the rotating power component 142, improve the overall support rigidity, and prevent the rotating shaft 141 from bending due to unilateral force. Simultaneously, the bearings 147 are completely housed within the second limiting portion 122 and protected by the mounting base 120, preventing external impurities from intruding and affecting operational performance, thereby ensuring the stable operation of the high-flow-rate drainage unit 140 under long-term, continuous drainage conditions.

[0043] Furthermore, the rotating power component 142 is fixedly installed on the second shaft section 1413 and can be driven to rotate under the action of water flow, thereby driving the entire rotating shaft 141 to rotate around its own axis.

[0044] Please see Figure 6 and Figure 7 In this embodiment, the second shaft segment 1413 of the rotating shaft 141 has a hexagonal shape, and the mounting hole of the rotating power component 142 matches the shape of the second shaft segment 1413. After the rotating power component 142 is fitted onto the second shaft segment 1413, it is fixed to the second shaft segment 1413 of the rotating shaft 141 by washers and screws to prevent the rotating power component 142 from coming off.

[0045] In other embodiments, the shape of the second shaft segment 1413 of the rotating shaft 141 may also be an octagonal structure and / or a threaded structure, as long as it matches the shape of the rotating power member 142.

[0046] Please see Figure 8In this embodiment, the rotating power component 142 is a rotating blade. In other embodiments, the rotating power component 142 may also be other structures capable of driving the rotating shaft 141 to rotate.

[0047] In this embodiment, a rotating blade is selected as the rotating power component 142. The rotating blade can rotate under the drive of the water flow, thereby driving the rotating shaft 141 to rotate along its axis. This design allows the high-flow-rate drainage unit 140 to operate automatically, relying solely on the energy of the water flowing through the drainage device, without the need for an external power source. Since the activation of the rotating power component 142 depends entirely on the water flow conditions during the actual drainage process, the high-flow-rate drainage unit 140 only starts working when there is a drainage demand, exhibiting good responsiveness and adaptability.

[0048] The passive drive method using rotating blades not only reduces the device's dependence on additional energy or control systems, improving system reliability and ease of maintenance, but also ensures timely activation of exhaust and flow amplification functions under different flow conditions, especially during high-flow drainage, thereby enhancing overall drainage efficiency. Furthermore, this structure avoids the introduction of complex electrical components, simplifying the device structure, reducing costs, and enhancing safety in humid environments.

[0049] Please see Figure 6 and Figure 7 Furthermore, the first shaft segment 1411 of the rotating shaft 141 is provided with a guide groove 1414. The guide groove 1414 extends along the shaft surface and has a continuously changing trajectory. The movable member 144 is accommodated in the guide groove 1414, so that when the rotating shaft 141 rotates, the movable member 144 accommodated in the guide groove 1414 can generate periodic axial reciprocating motion under its guidance.

[0050] In this embodiment, to ensure that the high-flow-rate drainage component 145 can achieve stable up-and-down reciprocating movement along the axial direction, there are two guide grooves 1414. The two guide grooves 1414 extend spirally along the axial direction on the surface of the first shaft section 1411, and the spiral directions of the two guide grooves 1414 are opposite, with their two ends connected to each other in the axial direction. Figure 6 and Figure 7 As shown.

[0051] Please see Figure 3 One end of the movable component 144 is located within the guide groove 1414 to receive motion conversion, and the other end protrudes from the guide groove 1414 and is connected in sequence to the guide component 146 and the connecting component 143. In this embodiment, the movable component is a slider.

[0052] Please see Figure 3 and Figure 9In this embodiment, the guide 146 is fitted onto the surface of the first shaft segment 1411 and is fixedly connected to the second limiting part 122 of the mounting base 120 by threads, so that the guide 146 is fixed to the mounting base 120.

[0053] The guide member 146 has a positioning groove 1461 extending along the axis. The part of the movable member 144 protruding from the guide groove 1414 passes through the positioning groove 1461 and is fixedly connected to the connector 143 at the end away from the guide groove 1414. The connector 143 is further fixedly connected to the high-flow drainage member 145, thereby transmitting the reciprocating linear motion of the movable member 144 to the high-flow drainage member 145, so that it can perform axial extension and contraction motion synchronously.

[0054] When the rotating shaft 141 rotates, the movable part 144 is subject to the dual limiting effect of the guide groove 1414 and the positioning groove 1461, and reciprocates in the axial direction of the rotating shaft 141. The movable part 144 cannot be radially offset or circumferentially rotated, thereby achieving precise guidance and constraint of the movement trajectory of the movable part 144.

[0055] Since the movable part 144 needs to convert the rotational motion of the rotating shaft 141 into a periodic reciprocating motion in the axial direction, and drive the high-flow drainage part 145 to move synchronously through the connecting part 143, the dual guiding effect provided by the guide part 146 and the positioning groove 1461 effectively prevents jamming or deflection during the movement process, and improves the smooth operation of the overall transmission mechanism.

[0056] Furthermore, the connector 143 is fitted onto the surface of the guide 146, effectively enhancing its guiding performance and structural stability during reciprocating motion. This arrangement allows the connector 143 to slide smoothly along the outer surface of the guide 146, reducing swaying and frictional resistance during movement. Simultaneously, under the impact of water flow, this structure helps reduce the influence of external disturbances on the movement path of the moving part 144, ensuring the operational reliability of the transmission system. Under the dual limiting effect of the positioning groove 1461 and the guide groove 1414, the moving part 144 is constrained within a predetermined axial movement range, preventing radial offset or rotation, further ensuring the accuracy of the movement trajectory. The synergistic effect of these structures facilitates long-term stable operation of the device under high-frequency reciprocating working conditions. Through the dual positioning and limiting effect of the positioning groove 1461 and the guide groove 1414, the movement path of the moving part 144 is clear and reliable. In addition, the connector 143 isolates most of the water flow on its outer side, thereby ensuring the accuracy of the conversion of the rotational power of the rotating shaft 141 into axial reciprocating motion.

[0057] Please see Figure 10 and Figure 2The drain panel 130 is provided with an opening 131, and the large flow drain component 145 is accommodated in the opening 131 and can be selectively extended or retracted outside or inside the opening 131 according to the movement state.

[0058] Please see Figure 2 During the drainage process, when the water volume is small, the water flows directly from the drainage panel 130 into the interior of the main body 110 and enters the drainage pipe. At this time, due to the small water flow, the water is discharged directly along the inner wall of the main body 110 and will not drive the large flow drainage unit 140.

[0059] When the water volume increases, the water flow washes over the rotating power component 142, causing it to rotate. This, in turn, drives the rotating shaft 141 to rotate. The movable component 144 reciprocates within the guide groove 1414 of the rotating shaft 141, causing the connecting component 143 and the high-flow-rate drainage component 145 to continuously reciprocate up and down. On the one hand, this causes the high-flow-rate drainage component 145 to periodically extend out of the drainage panel 130, effectively expanding the drainage contact area and increasing the drainage volume per unit time. On the other hand, during the reciprocating motion, the relative position between the high-flow-rate drainage component 145 and the drainage panel 130 continuously changes, forming a dynamic ventilation gap. Even when the water flow submerges the drainage panel 130, this dynamic gap allows for the timely discharge of gas from inside the pipe, preventing drainage problems caused by air resistance.

[0060] Understandably, both the drainage panel 130 and the high-flow drainage component 145 have multiple through slots to allow water to enter the drainage device, thereby improving the water intake efficiency and flow capacity of the drainage device.

[0061] In this embodiment, the drainage panel 130 is a horizontal plate structure and is located at the water inlet end face of the drainage device. Therefore, the slots provided on the drainage panel 130 are all axially connected so that water can enter the drainage device through the slots of the drainage panel 130.

[0062] In this embodiment, the high-flow-rate drainage component 145 is a cylindrical structure with one end open, and both the side wall and bottom wall of the high-flow-rate drainage component 145 are provided with through slots so that water can enter the drainage device from the high-flow-rate drainage component 145.

[0063] In this embodiment, when the high-flow drainage unit 140 is not working, the bottom wall of the high-flow drainage component 145 is on the same horizontal plane as the drainage panel 130; when the high-flow drainage unit 140 is working, the bottom wall of the high-flow drainage component 145 extends out of the surface where the drainage panel 130 is located.

[0064] In other embodiments, the shape of the high-flow-rate drainage component 145 may be any of the following: prism, cone, or frustum, or a complex irregular structure composed of several of these shapes, as long as the structure can achieve axial reciprocating movement to assist in drainage and venting.

[0065] The drainage device provided in this embodiment utilizes the energy of the water flow itself to drive mechanical movement, requiring no external power source. It is reliable in operation and has low maintenance costs, making it particularly suitable for gravity flow drainage scenarios such as roofs or floors. Under high-flow drainage conditions, it can still maintain good air venting performance and drainage capacity, thereby effectively solving the problem of reduced water flow velocity caused by air accumulation in pipes in traditional drainage systems.

[0066] The high-flow-rate drainage device 100 provided in this embodiment has the following installation process and working principle: Please see Figure 2 First, the main body 110 is arranged axially and fixed at the drainage pipe interface, ensuring that the first installation section 111 of the main body 110 faces the water inlet direction and the second installation section 112 faces the water outlet direction. Then, the mounting base 120 is installed in the second installation section 112 of the main body 110, so that the first limiting part 121 of the mounting base 120 cooperates with the fourth limiting platform 1121 to achieve axial positioning.

[0067] The shoulder 1412 and bearing 147 of the rotating shaft 141 are located within the second limiting portion 122 of the mounting base 120 and are limited by the first limiting platform 1221. The rotating power component 142 is sleeved on the second shaft section 1413 of the rotating shaft 141 and is fastened with shims and screws to prevent it from falling off. The guide component 146 is sleeved on the surface of the first shaft section 1411 of the rotating shaft 141. One end of the movable component 144 is embedded in the guide groove 1414 opened on the surface of the first shaft section 1411 of the rotating shaft 141, and the other end passes through the positioning groove 1461 on the guide component 146 and is fixedly connected to the connecting component 143. The connecting component 143 is fixedly connected to the high-flow drainage component 145.

[0068] Next, the drainage panel 130 is placed inside the first mounting section 111 of the main body 110, and the drainage panel 130 is axially limited and fixed by the third limiting platform 1112, so that the drainage panel 130 is stably installed at the water inlet end face of the main body 110. The high-flow drainage component 145 is accommodated in the opening 131 of the drainage panel 130, completing the integrated installation of the entire high-flow drainage unit 140 inside the main body 110.

[0069] When the drainage device is in low-flow drainage mode, less water enters the main body 110. The water mainly flows along the inner wall of the main body 110 and flows directly into the main body 110 through the through slot on the drainage panel 130, and then is discharged into the downstream drainage pipe. At this time, since the water flow is insufficient to drive the rotating power component 142 to generate effective torque, the rotating power component 142 remains stationary, the rotating shaft 141 does not rotate, the moving part 144 remains in its original position under the dual constraints of the guide groove 1414 and the positioning groove 1461, and the high-flow drainage component 145 also remains in its initial position, that is, the bottom wall is basically flush with the plane of the drainage panel 130. It achieves the normal drainage function only through itself and the through slot on the drainage panel 130, which meets the daily low-flow drainage needs.

[0070] When the drainage device enters the high-flow-rate drainage mode, a large amount of water continuously enters the main body 110 from the inlet end and impacts the rotating power component 142, causing the rotating power component 142 to begin rotating around the axis of the rotating shaft 141 under the action of the water flow, thereby driving the rotating shaft 141 to rotate synchronously. As the rotating shaft 141 rotates, the guide groove 1414 provided on the surface of its first shaft section 1411 guides the movable component 144 to move within the groove. Since the guide groove 1414 has a continuously changing spiral trajectory and there are two of them, with opposite spiral directions and connected at both ends in the axial direction, the movable component 144 is forced to generate periodic axial reciprocating motion during rotation. This reciprocating motion is transmitted to the connecting component 143 through the movable component 144, and further drives the high-flow-rate drainage component 145 to move synchronously up and down along the axial direction.

[0071] During this process, the high-flow-rate drainage component 145 periodically extends or retracts from the opening 131 of the drainage panel 130. When it extends, it expands the drainage contact area, allowing more water to enter the device through the through slots on the side and bottom walls of the high-flow-rate drainage component 145, significantly improving the water intake capacity and drainage efficiency per unit time. Simultaneously, during the reciprocating motion of the high-flow-rate drainage component 145, a dynamically changing air gap is continuously formed between it and the drainage panel 130. Even when the water surface completely submerges the drainage panel 130, the gas accumulated inside the drainage pipe can still be discharged in a timely manner through this dynamic gap, effectively avoiding drainage problems caused by air resistance and ensuring stable operation of the system under high-load drainage conditions. All of the above actions are driven by the energy of the water flow itself, requiring no external power source, achieving an integrated function of automatic response, efficient drainage, and active venting.

[0072] Second Embodiment Please refer to Figure 11 This embodiment provides a large flow drainage device 100, which has a similar structure to the first embodiment, except that the drainage device provided in this embodiment is also provided with a flow guide 150.

[0073] Please refer to Figure 12 In this embodiment, the guide member 150 has a trumpet-shaped structure, with a large diameter end and a small diameter end. The large diameter end is fixedly connected to the inner wall of the main body 110 and belongs to the water inlet end of the guide member 150; the small diameter end is spirally connected to the rotating power member 142 on one side and belongs to the water outlet end of the guide member 150.

[0074] Therefore, it is understandable that the flow guide 150 is disposed within the main body 110, and the large flow drainage unit 140, except for the rotating power component 142 which is located outside the flow guide 150, has all other structures partially or entirely located within the flow guide 150.

[0075] Furthermore, the inner wall surface of the guide member 150 is provided with a spiral guide rib 151, which extends spirally from the large diameter end to the small diameter end of the guide member 150.

[0076] During drainage, water enters from the inlet of the main body 110 and flows into its internal space through the large-diameter end of the guide member 150. At this time, the water flow forms a spiral flow under the guidance of the guide ribs 151 on the inner wall of the guide member 150. Since the guide ribs 151 are spirally arranged, they can apply a tangential force to the water flow entering the guide member 150, causing the water flow to gradually form a stable swirling state as it flows towards the small-diameter end.

[0077] This swirling state allows the water flow to quickly drive the rotating power component 142 to rotate when it flows through the guide component 150 into the rotating power component 142, thereby enabling the connecting component 143 and the high-flow drainage component 145 to be driven quickly, shortening the start-up response time of the drainage device.

[0078] Because the spiral guide ribs 151 on the inner wall of the guide member 150 pre-apply a directional swirling effect to the water flow, the water flow enters its working area with an angular momentum that matches the rotation direction of the rotating power member 142, thereby improving the efficiency of water flow energy conversion into mechanical torque. This flow matching effect reduces the starting torque required for the initial rotation of the rotating power member 142, enabling rapid start-up and stable operation even under low flow or instantaneous water intake conditions.

[0079] Meanwhile, the swirling driving force continuously provided by the water flow is effectively transmitted to the high-flow-rate drainage component 145 through the connector 143, ensuring that the high-flow-rate drainage component 145 can reach an effective drainage state in the early stage of system operation, thereby improving the response capability and processing efficiency of the entire drainage device to sudden large-scale drainage demands.

[0080] Furthermore, to facilitate the installation of the guide component 150, a second limiting platform 1111 is also provided in the first installation section 111 of the main body 110. The large-diameter end of the guide component 150 is fixed to the main body 110 through the second limiting platform 1111 and is sealed to the main body 110 through a sealing component.

[0081] In this embodiment, to ensure that the water flow is transformed into a swirling flow after passing through the guide member 150, and that the swirling flow can be stably transmitted to the rotating power member 142, the small-diameter end of the guide member 150 is basically horizontal with the upper surface of the rotating power member 142. To ensure stable installation of the guide member 150, three mounting grooves 152 are provided on the guide member 150, each mounting groove 152 corresponding to a connecting part 123, and the mounting groove 152 fits onto the surface of the connecting part 123.

[0082] Therefore, when the number of connecting parts 123 of the mounting base 120 changes, the number of mounting slots 152 also needs to be changed accordingly to ensure that the guide member 150 can be installed stably.

[0083] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
