Description

Technical Field

[0001] This invention relates to the field of municipal engineering technology, specifically to a rainwater collection device for municipal roads based on rainwater and sewage separation. Background Technology

[0002] The initial rainwater collection device for municipal roads with separate stormwater and sewage systems is a specialized piece of equipment in the field of municipal engineering that serves the stormwater and sewage separation system. It is mainly designed to handle polluted rainwater generated on the road surface during the initial stage of rainfall (usually 15-30 minutes after the start of rainfall). At this stage, the rainwater carries various impurities such as mud, fallen leaves, and domestic waste due to the scouring of the road surface, resulting in a high concentration of pollution. Its core function is to intercept, separate impurities, and temporarily store clean rainwater through a pre-designed structure, preventing highly polluted rainwater from directly entering the municipal stormwater or sewage pipe network. This lays the foundation for subsequent rainwater diversion, transportation, treatment, and resource utilization, while also reducing the blockage and damage to the pipe network system caused by impurities.

[0003] Existing rainwater harvesting devices for municipal roads typically have a filtration and storage structure built under the manhole cover of the road inspection well. When it rains, rainwater and road debris enter the device through the inlet channel in the manhole cover. First, it passes through the surface filtration components (such as metal mesh, grilles, etc.) to intercept larger debris (such as stones, branches, large pieces of garbage, etc.). The filtered rainwater then flows into the storage space below for temporary storage.

[0004] However, in actual use, existing rainwater collection devices for municipal roads with separate storm and sewage systems have two main problems: First, they lack a dedicated directional flow guidance and zoned collection structure. After initial rainwater is filtered, impurities tend to accumulate on the surface of the filter components or spread with the rainwater, failing to be concentrated and guided to a dedicated collection space. This results in incomplete separation of rainwater and sewage, affecting the cleanliness of the stored water and increasing the difficulty of subsequent impurity removal. Second, they lack an active mechanism to assist in the removal of impurities. The filter components rely solely on their own pore size to intercept impurities, without external force to help them fall off the filter surface. During rainfall, mesh blockage, reduced rainwater throughput, and even rainwater overflow are likely to occur, making it difficult to guarantee stable collection efficiency in the early stages of rainfall. In view of this, we propose a rainwater collection device for municipal roads with separate storm and sewage systems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rainwater collection device for municipal roads based on rainwater and sewage separation, which solves the problems of existing devices lacking directional flow guidance, auxiliary impurity removal, and collaborative filtration, resulting in poor rainwater and sewage separation efficiency.

[0012] Preferably, the inner surface of the water storage tank has multiple sets of arc-shaped through holes, the outer arc surface of the rotating shaft has an arc-shaped groove, the end of the blade away from the rotating shaft is provided with an arc-shaped sealing ring, the lower end of the rotating shaft is provided with a cylindrical protrusion, the outer arc surface of the rotating shaft is elastically connected to the water storage tank by a spiral spring, multiple sets of tooth blocks are provided, and the multiple sets of tooth blocks are arranged in a circumferential array with the center of the ring block as the array center, and the outer surface of the contact rod is in contact with the outer arc surface of the blade.

[0013] Preferably, both the upper and lower ends of the sleeve are provided with through holes, the inner diameter of the sleeve is the same as the outer diameter of the connecting block, and the upper and lower sets of connecting blocks are elastically connected by springs.

[0014] Preferably, the storage box has a rectangular through hole near the ring block, the module and pressure angle of the drive gear are the same as those of the outer teeth of the ring block, and the lower part of the motor is electrically connected to the municipal power supply line via a cable.

[0015] Preferably, the rainwater collection device further includes a fixed filter plate, the outer arc surface of which is fixedly connected to the water storage tank, an elastic telescopic rod is fixedly connected to the inner surface of the fixed filter plate, a movable filter plate is fixedly connected to the movable end of the elastic telescopic rod, and a magnetic block is fixedly connected to the middle of the inner surface of the water storage tank.

[0016] Preferably, the filter holes inside the fixed filter plate and the movable filter plate are staggered, the lower part of the inner surface of the fixed filter plate is provided with an arc-shaped groove, the outer arc surface of the movable filter plate is slidably connected to the water storage tank, and the lower surface of the movable filter plate is made of magnetic metal.

[0017] Working Principle: In rainy weather, rainwater and impurities fall through the openings in the manhole cover to the main filter screen. Since impurities cannot pass through the main filter screen and rainwater is fluid, some rainwater falls directly, while the rest carries impurities and moves along the slope of the main filter screen towards the manhole wall. Because the manhole wall has a drain outlet, some rainwater and impurities move along the slopes of the main filter screen and the drain outlet into the collection chamber. Simultaneously, because the lower part of the collection chamber is sloped, the rainwater, due to its own gravity, moves towards the secondary filter holes and then flows downwards along the manhole wall to be collected in the water storage tank. Meanwhile, as the rainwater falls... During the process, the main filter screen will be constantly impacted, and due to the spring installed at the bottom of the main filter screen, the main filter screen will continuously vibrate, thus creating a shaking effect to help impurities fall into the collection chamber. At the same time, when the upper manhole cover is squeezed by external force, its middle part will have a downward movement tendency. At this time, the connecting block will be driven downward, and through its lower spring, it will push the lower connecting block to vibrate, assisting the main filter screen in separating rainwater and sewage. When the manhole cover is subjected to a large impact force, the two sets of connecting blocks will transfer the impact force to the lower main filter screen, and the main filter screen will also descend until its bottom contacts the support ring. The support ring provides auxiliary support to the upper manhole cover, improving its pressure resistance.

[0018] When collecting and cleaning impurities, the hatch cover needs to be opened separately, and the impurities accumulated inside the collection chamber are scooped out with a net bag, without opening the manhole cover. Since the manhole cover and the manhole wall are generally designed to not be opened and closed frequently, repeated operation will directly damage its structural stability and accelerate the wear of its connection. Therefore, this device can maintain a long service life.

[0019] Furthermore, in environments where the average winter temperature is above 0°C, the collected rainwater employs a structure design with both fixed and movable filter plates. When rainwater falls onto the fixed filter plate, it doesn't immediately trigger collection. Once a certain amount of rainwater has been collected, the weight of the rainwater exceeds the elastic force of the telescopic rod, causing the movable filter plate to move downwards and adhere to the magnetic block. The rainwater then falls through the gap between the fixed and movable filter plates and is collected inside the storage tank. Due to the magnetic attraction of the magnetic block to the movable filter plate, the elastic rod only moves the movable filter plate upwards when the weight of the rainwater plus the magnetic attraction force is less than the rebound force of the telescopic rod. This causes the two filter plates to fit together and form a seal, preventing the large-scale natural evaporation of collected rainwater.

[0020] In environments where the average winter temperature is below 0°C, such as in northern regions, there is a risk of freezing when the initially collected rainwater is located above the fixed filter plate and the movable filter plate is not triggered to descend. The frozen ice will block the collection of subsequent rainwater. In this case, an electronic control method is needed to control the sealing of the water storage tank. When the weather station reports that it is currently raining, the motor in the corresponding area of ​​the city needs to be controlled to run forward. The drive gear drives the ring block with toothed blocks on the outside to rotate. At this time, the contact rod will gradually move away from the blades, and the spiral spring at the blade shaft will drive multiple sets of blades to gradually move away through its own elasticity, thereby exposing the water storage tank below, so that rainwater can directly enter the water storage tank. After receiving a signal that the rain has stopped, the motor drives the drive gear to reverse, which causes the ring block to drive the contact rod to move closer to the blades. At this time, the blades will move inward into the water storage tank due to the compression of the contact rod, and gradually form a seal on the water storage tank.

[0021] This invention provides a rainwater harvesting device for municipal roads based on a rainwater and sewage separation system. It has the following beneficial effects:

[0022] 1. This invention, through its collection chamber, cover, drain outlet, secondary filter holes, support ring, and main filter screen, enables rainwater to be filtered and separated during its fall. Impurities move into the collection chamber, while rainwater falls into the storage chamber. The impact force of the falling rainwater and the vibration force generated when the manhole cover is squeezed by external force further assist the impurities on the surface of the main filter screen in moving into the collection chamber. Thus, the initial separation and collection of rainwater and impurities can be completed without the use of electricity, which is in line with the concept of green and environmentally friendly use.

[0023] 2. The present invention, through the setting of a water storage tank, blades, ring block, contact rod, toothed block, rotating shaft, and spiral spring, enables the ring block to rotate via a motor after rainwater falls into the water storage tank, and pushes multiple sets of blades to close via the contact rod above the ring block, thereby preventing the collected rainwater from evaporating naturally. At the same time, the sealing ring on the outside of the blades can further ensure the sealing effect of the water storage tank. In addition, the electronically controlled sealing can prevent environmental factors from affecting rainwater collection.

[0024] 3. The elastic telescopic rod, fixed filter plate, movable filter plate, and magnetic block set in this invention can extend the elastic telescopic rod when rainwater falls above the movable filter plate due to the weight of the rainwater itself. This creates a gap between the fixed filter plate and the movable filter plate to allow rainwater to fall into the water storage tank. The attraction between the movable filter plate and the magnetic block creates a delay in the reset of the movable filter plate. Thus, automatic rainwater collection can be completed without the need for electrical control equipment, which is in line with the concept of green and environmentally friendly use.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides an initial rainwater collection device for municipal roads based on rainwater and sewage separation, including a manhole cover 1, a manhole wall 5 that is snapped onto the outer arc surface of the manhole cover 1, a rainwater and sewage separation device 2 that is provided on the inner side of the manhole wall 5 for preliminary separation of impurities and rainwater during the rainwater collection process, and a rainwater collection device 4 that is provided below the manhole wall 5 for storing and collecting the separated rainwater.

[0036] The rainwater and sewage separation device 2 includes a main filter screen 206 and a vibration connection assembly 3. The outer arc surface of the main filter screen 206 is slidably connected to the well wall 5. A support ring 205 is fixedly connected to the middle of the inner arc surface of the well wall 5. A collection chamber 201 is fixedly connected to the outer arc surface of the well wall 5. A cover 202 is snapped onto the upper end of the collection chamber 201. A secondary filter hole 204 is opened at the middle of the well wall 5 where it is flush with the lower inner edge of the collection chamber 201.

[0037] The inner surface of the manhole cover 1 has multiple sets of through-holes, allowing large debris to be blocked while rainwater can pass through normally. The middle of the manhole wall 5 has multiple sets of arc-shaped drain outlets 203, allowing debris and some rainwater to be guided into the collection chamber 201 through the inclined drain outlets 203. The drain outlets 203 are inclined, and the main filter screen 206 is frustum-shaped, allowing debris falling on the upper surface of the main filter screen 206 to move towards the drain outlets 203 due to gravity and being carried by rainwater. Multiple springs are fixedly connected to the lower surface of the main filter screen 206, causing it to vibrate under rainwater impact or pressure from the manhole cover 1 above, thus aiding in the shaking off of debris and improving the continuous filtering effect of the main filter screen 206. The filter has good filtration performance, and multiple sets of springs are arranged in a circular array with the center of the main filter screen 206 as the array center. The upper surface of the support ring 205 is in contact with the lower spring of the main filter screen 206 to provide support for the upper main filter screen 206. At the same time, when the manhole cover 1 is subjected to greater pressure, the support ring 205 can also provide auxiliary support for the middle of the manhole cover 1, reducing the risk of plastic deformation caused by impact. The lower part of the inner surface of the collection chamber 201 is set in an inclined shape, so that rainwater will pass through the secondary filter hole 204 and re-enter the inner side of the manhole wall 5 due to its own gravity. The inner arc surface of the collection chamber 201 is fixedly connected to the manhole wall 5. The inner arc surface of the cover 202 is in sealed contact with the manhole wall 5. Multiple sets of secondary filter holes 204 are provided, and the multiple sets of secondary filter holes 204 are arranged in a circular array with the center of the manhole wall 5 as the array center.

[0038] Please see the appendix Figure 1 Appendix Figure 5 and appendix Figure 6 The rainwater collection device 4 includes a water storage tank 401 and a drive connection assembly 6. A rotating shaft 406 is rotatably connected to the inner wall of the water storage tank 401. A blade 402 is fixedly connected to the outer arc surface of the rotating shaft 406. A spiral spring 407 is fixedly connected to the lower end of the rotating shaft 406. A ring block 403 is rotatably connected to the outer arc surface of the water storage tank 401. A toothed block 405 is fixedly connected to the outer arc surface of the ring block 403. A contact rod 404 is fixedly connected to the upper end of the ring block 403.

[0039] The inner surface of the water storage tank 401 has multiple sets of arc-shaped through holes, which can accommodate the movement of the blades 402 inside. An arc-shaped groove is provided on the outer arc surface of the rotating shaft 406 to prevent motion interference between the blades 402 and the rotating shaft 406 during rotation. An arc-shaped sealing ring is provided at the end of the blades 402 away from the rotating shaft 406, which further enhances the sealing of the water storage tank 401 when multiple sets of blades 402 are closed together. A cylindrical protrusion is provided at the lower end of the rotating shaft 406 for connecting... One end of the spiral spring 407 is elastically connected to the water storage tank 401 at the outer arc surface of the rotating shaft 406 via the spiral spring 407. Multiple sets of toothed blocks 405 are provided, and the multiple sets of toothed blocks 405 are arranged in a circumferential array with the center of the ring block 403 as the array center. The outer surface of the contact rod 404 contacts the outer arc surface of the blade 402. The number of contact rods 404 is the same as the number of blades 402. Therefore, during the rotation of the contact rod 404, it can push the corresponding multiple sets of blades 402 to move inward toward the water storage tank 401.

[0040] Please see the appendix Figure 2 - Appendix Figure 4 The vibration connection assembly 3 includes a sleeve rod 301, and a connecting block 302 is slidably connected to the inner arc surface of the sleeve rod 301. There are two sets of connecting blocks 302, and the two sets of connecting blocks 302 are symmetrically distributed with the center line of the sleeve rod 301 as the axis of symmetry. The upper connecting block 302 is fixedly connected to the well cover 1, and the lower connecting block 302 is fixedly connected to the main filter screen 206.

[0041] Both ends of the sleeve 301 have through holes to accommodate the connecting block 302 sliding inside. The inner diameter of the sleeve 301 is the same as the outer diameter of the connecting block 302. The upper and lower sets of connecting blocks 302 are elastically connected by springs. Therefore, when the manhole cover 1 is impacted, the upper connecting block 302 will be impacted as well, causing the spring to vibrate.

[0042] Please see the appendix Figure 5The drive connection component 6 includes a storage box 602, on the bottom inner surface of which a motor 604 is fixedly connected. This motor 604 is a servo motor (including a servo motor) that supports remote control of its rotation direction and opening / closing via PWM or bus signals. During the process, the motor 604 connects to the existing municipal smart management system (such as the city's IoT transmission link or municipal control platform), eliminating the need for an additional independent signal system. Only the weather station signal needs to be connected to the municipal smart platform, and then the platform can output forward (driving the ring block to open the blades during rainfall) or reverse (driving the ring block to close the blades when rainfall stops) operation commands to the motor 604 to complete signal transmission and motor control. The motor 604 is an MG996R servo motor (including servo motor function); operating voltage: DC1. 2V (compatible with municipal low-voltage power supply); Rated torque: 13kg·cm; Speed: 50-100rpm; Control signal: PWM signal (frequency 50Hz, duty cycle 5%-10% corresponds to forward rotation, 15%-20% corresponds to reverse rotation), supports remote control via municipal smart platform bus signal (such as RS485), the output shaft of motor 604 is fixedly connected to drive gear 603, the outer arc surface of drive gear 603 meshes with tooth block 405, the upper end of storage box 602 is rotatably connected to box cover 601, therefore, when setting up this device, it is necessary to excavate a rectangular space larger than storage box 602 on the outside of well wall 5 for placing storage box 602, and the reserved gap space is for operators to inspect and maintain motor 604.

[0043] The storage box 602 has a rectangular through hole near the ring block 403, so that the drive gear 603 can mesh with the tooth block 405 through the through hole. The module and pressure angle of the drive gear 603 are the same as those of the outer tooth block 405 of the ring block 403. The lower part of the motor 604 is electrically connected to the municipal power supply line through a cable.

[0044] Example 2:

[0045] Please see the appendix Figure 1 and appendix Figure 7 The rainwater collection device 4 also includes a fixed filter plate 409, the outer arc surface of which is fixedly connected to the water storage tank 401, an elastic telescopic rod 408 is fixedly connected to the inner surface of the fixed filter plate 409, a movable filter plate 410 is fixedly connected to the movable end of the elastic telescopic rod 408, and a magnetic block 411 is fixedly connected to the middle of the inner surface of the water storage tank 401.

[0046] The filter holes inside the fixed filter plate 409 and the movable filter plate 410 are interlocked. Therefore, when the two are tightly fitted together, the filter holes inside them will block each other, thus forming a seal on the water storage tank 401. The lower part of the inner surface of the fixed filter plate 409 has an arc-shaped groove to accommodate the elastic telescopic rod 408 located inside it. The elastic telescopic rod 408 has an elastic coefficient of 5-8 N / mm, a stroke of 30-50 mm, a rated load of 50-80 N, and a reset time of ≤2 s (after the rainwater gravity disappears, the movable filter plate is reset by the elastic force). The outer arc surface of the movable filter plate 410 is slidably connected to the water storage tank 401. The lower surface of the movable filter plate 410 is made of magnetic metal, so it can be attracted to the magnetic block 411 when it is close to the magnetic block 411.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
