Description

Technical Field

[0001] This utility model relates to the technical field of rainwater and sewage separation devices, and in particular to a modular rainwater and sewage separation device. Background Technology

[0002] Separate stormwater and wastewater systems collect and transport stormwater and wastewater separately, reducing the risk of pollutants entering natural water bodies at the source. This helps improve drainage efficiency and alleviate the burden on wastewater treatment, making it the mainstream design approach for modern urban drainage systems. In existing technologies, when mixed or mistakenly connected stormwater pipes are found to be discharging dissolved pollutants with rainwater, methods such as interception, storage, or modification are typically used to address the issue, mitigating or even eliminating the discharge of wastewater from stormwater outlets.

[0003] For example, the applicant's earlier application, Chinese Utility Model Patent No. CN 219011407 U, discloses a diversion pool, including a main body. A water-blocking plate is provided on one side of the main body. The water-blocking plate is divided into a fixed part and a movable part. The fixed part is located at the bottom of the main body, and the movable part is driven by a driving device to move up and down. During the up and down movement of the movable part, one side of the movable part is always in close contact with the fixed part. When the river water level rises rapidly, the driving device drives the movable part of the water-blocking plate to rise, preventing river water from flowing back into the diversion pool. When the water level in the diversion pool rises rapidly but is lower than the river water level, the height of the movable part can be lowered, allowing the water in the diversion pool to overflow into the river channel, avoiding drainage difficulties.

[0004] However, the diversion pool in the aforementioned patent CN 219011407 U has certain shortcomings for large-scale mass production: First, while the liftable baffle plate offers high flexibility, its single-point construction cost is high, making a fixed weir more suitable for construction scenarios with small catchment areas; second, due to the integrated design, different diversion pool entities need to be customized individually, and the lack of modular components leads to high complexity in design, manufacturing, and parts maintenance. These problems limit the adaptability, maintenance convenience, and long-term operational stability of the device.

[0005] Therefore, the existing rainwater and sewage separation devices still need further improvement. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a modular rainwater and sewage separation device that is convenient for on-site installation and easy for subsequent maintenance, in light of the current state of the technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a modular rainwater and sewage separation device, comprising:

[0008] The diversion tank includes a box, and the side wall of the box is provided with an inlet pipe interface and an outlet pipe interface;

[0009] A water-blocking plate assembly is disposed inside the box;

[0010] The water-blocking plate assembly includes a vertically extending water-blocking base plate and a vertically extending water-blocking movable plate located above the water-blocking base plate. There is at least one water-blocking movable plate, and the number of the movable plates can be selected and detachably installed on the water-blocking base plate to change the overall height of the water-blocking plate assembly.

[0011] The phrase "in a way that the quantity can be selected" can be understood as follows: according to the actual needs of the on-site installation environment, an appropriate number of water-blocking movable plates can be selected, that is, the number of water-blocking movable plates installed can be increased or decreased.

[0012] By combining a water-blocking base plate with a detachable movable water-blocking plate, the number of movable plates can be selected according to actual needs, dynamically adjusting the overall height of the water-blocking plate assembly to optimize the rainwater and sewage separation effect and improve the adaptability of the device. Specifically, this modular water-blocking plate assembly is prefabricated and assembled on-site, reducing the civil construction cycle (shortening the construction period by 60% compared to traditional solutions). After the diversion device is installed, if the height of the water-blocking plate needs to be adjusted, the overall height of the water-blocking plate can be quickly raised or lowered by adding or removing movable water-blocking plates, reducing the complexity of secondary construction and meeting the needs of rapid deployment. When the water-blocking plate module fails, it can be replaced and maintained independently; if the water-blocking plate is damaged, only the water-blocking module needs to be removed.

[0013] Considering the unstable connection between the water-blocking movable plate and the base plate or housing, which is prone to displacement or tilting due to water flow impact, affecting the water blocking and diversion effect, to ensure the stability of the connection between the water-blocking movable plate and the base plate or housing, the water-blocking base plate has two front-to-back, vertically extending first mounting grooves. The front and rear edges of the water-blocking movable plate are limited in the corresponding two first mounting grooves, and the bottom edge of the water-blocking movable plate abuts against the top of the main body of the water-blocking base plate; or

[0014] The inner sides of the two opposite side walls of the box are each constructed with a vertically extending first mounting groove. The front and rear edges of the water-blocking movable plate are limited in the corresponding two first mounting grooves, and the bottom edge of the water-blocking movable plate abuts against the top of the main body of the water-blocking base plate.

[0015] By setting the first mounting groove to limit the front and rear edges of the water-blocking movable plate, combined with the bottom abutting against the base plate, the movable plate is vertically and stably fixed, ensuring that the water-blocking plate assembly maintains structural stability in dynamic water flow.

[0016] To further improve the reliability and sealing of the connection between the water-blocking base plate and the water-blocking movable plate, the top of the water-blocking base plate has a second, laterally extending mounting groove. The bottom edge of the water-blocking movable plate is confined within the second mounting groove. Sealing strips are also provided between the water-blocking base plate and the water-blocking movable plate, as well as between two adjacent water-blocking movable plates. The laterally extending second mounting groove precisely confines the bottom edge of the water-blocking movable plate, enhancing the reliability of the connection between the base plate and the movable plate.

[0017] As an improvement, the outer periphery of the water-blocking movable plate has a first folded edge that bends to one side and is perpendicular to the main body of the water-blocking movable plate. The widths of the first mounting groove and the second mounting groove on the water-blocking base plate are adapted to the bending height of the first folded edge. The bending height of the first folded edge is adapted to the width of the corresponding mounting groove. Through the fitting design of the folded edge and the groove, the connection tightness is improved, while simplifying the installation and disassembly process.

[0018] The water-blocking substrate can be detachably connected to the side of the housing or fixedly connected to the housing. To ensure a reliable connection between the water-blocking substrate and the housing, the water-blocking substrate is fixedly connected to the side of the housing. Directly fixing the water-blocking substrate to the side of the housing enhances the overall structural rigidity, prevents component misalignment due to external forces, and ensures long-term stable operation of the diversion device.

[0019] As an improvement, at least two water-blocking movable plates are provided, and each water-blocking movable plate can be sequentially connected from the top of the water-blocking base plate upwards. The bottom edge of the bottommost water-blocking movable plate is limited in the second mounting groove, and the front and rear edges of the remaining water-blocking movable plates are limited in the corresponding two first mounting grooves. By stacking multiple water-blocking movable plates from bottom to top, the height of the water-blocking plate assembly is gradually expanded, increasing the applicability of the device and flexibly responding to extreme rain and sewage conditions.

[0020] To further improve the modularity of the rainwater and sewage separation device, the two opposite side walls of the housing have openings and mounting plates covering these openings. The mounting plates are equipped with corresponding inlet or outlet pipe interfaces. This design of openings and detachable mounting plates enables modular installation of the interfaces, facilitating quick replacement or adjustment of water pipe positions and increasing the flexibility of on-site construction.

[0021] Considering that traditional diversion devices lack effective filtration structures, and impurities can easily clog pipes or affect diversion efficiency, a detachable basket grille assembly is also included, placed inside the housing, to filter the water flow entering from the inlet pipe interface. The introduction of the detachable basket grille assembly can intercept solid impurities, prevent pipe blockage, and facilitate regular cleaning, thus extending the device's service life.

[0022] As an improvement, the basket grille assembly includes a main basket and at least one auxiliary basket. The main basket has a first inlet on the side facing the water inlet pipe interface. Each of the auxiliary baskets is disposed inside the main basket and has a second inlet at its top. When each of the auxiliary baskets is in place in the main basket, the second inlet of each auxiliary basket is lower than the water inlet pipe interface. The main basket also has an installation port for the auxiliary baskets to enter and exit the main basket. The front and rear sides of the main basket are provided with outwardly protruding and vertically extending positioning flanges. The interior of the housing has a vertically extending third mounting groove at a position opposite to the positioning flanges. The positioning flanges on the main basket are confined in the third mounting groove and can move up and down along the third mounting groove. The basket grille assembly adopts a modular design, especially the nested structure arrangement of the main basket and auxiliary baskets. When the basket grille assembly is clogged, the operator can lift the auxiliary baskets for cleaning, making subsequent operation and maintenance more flexible and convenient. The positioning protrusion of the main basket and the cooperation of the third mounting groove ensure the stability of the vertical movement of the filter basket.

[0023] As an improvement, the enclosure includes a main body with an open top and a detachable brim module connected to the open top of the main body. The brim module has an operating port for manual operation. The design of the brim module and operating port provides convenient access for manual operation, facilitating routine maintenance or adjustment of the water-blocking plate assembly and improving maintenance efficiency. The detachable design between the brim module and the main body is primarily to accommodate variations in the burial depth of the diversion pool during construction, typically ranging from 2 to 4 meters. However, the main body of the enclosure is usually a fixed size. To accommodate different depths, the main body and the brim module can be directly connected, or the brim can be attached by constructing a brickwork structure on top of the main body, forming a single unit.

[0024] Compared with existing technologies, the advantages of this utility model are as follows: The rainwater and sewage diversion device of this utility model adopts a modular water-blocking plate assembly. The water-blocking plate assembly includes a vertically extending water-blocking base plate and a vertically extending movable water-blocking plate located above the base plate. There is at least one movable water-blocking plate, and their number can be selected for detachable installation on the base plate to change the overall height of the water-blocking plate assembly. This modular water-blocking plate assembly is prefabricated and assembled on-site, reducing the civil construction cycle (shortening the construction period by 60% compared to traditional solutions). After the diversion device is installed, if the height of the water-blocking plate needs to be adjusted, it can be quickly raised or lowered by adding or removing the movable water-blocking plates, reducing the complexity of secondary construction and meeting the needs of rapid deployment. When the water-blocking plate module fails, it can be replaced and maintained independently; if the water-blocking plate is damaged, only the water-blocking module needs to be disassembled. In a preferred embodiment, the basket grille assembly also adopts a modular design. When the basket grille assembly is clogged, the operator can lift the auxiliary basket for cleaning, making subsequent operation and maintenance more flexible and convenient.

For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0034] Figures 1-7 A preferred embodiment of a modular rainwater and sewage separation device is shown. The modular rainwater and sewage separation device includes a separation tank and a water-blocking plate assembly. The tank body 10 is made of corrosion-resistant metal, and its side walls are provided with an inlet pipe interface 121 and an outlet pipe interface 122, arranged opposite each other. Openings are formed on the two opposite side walls of the tank body 10, and mounting plates 12 are fixed with bolts. Standard-sized interfaces are pre-installed on the mounting plates 12 to accommodate pipes of different diameters. These interfaces on the mounting plates 12 are the aforementioned inlet pipe interface 121 and outlet pipe interface 122. In this embodiment, the inlet pipe interface 121 and outlet pipe interface 122 of the rainwater and sewage separation device adopt a modular structural design. The corresponding connection points between the mounting plate 12 and the tank body 10 are standardized. The drilling positions on the tank body 10 are fixed to the drilling positions on the mounting plate 12 modules, while the inlet and outlet pipe diameters can be changed according to the actual site conditions. The inlet and outlet water pipe interfaces are welded and spliced ​​to the main body of the box 10 before leaving the factory to ensure the sealing of the inlet and outlet water pipes.

[0035] See Figure 3The water-blocking plate assembly is located inside the housing 10 and includes a water-blocking base plate 21 and a water-blocking movable plate 22. The water-blocking base plate 21 is vertically fixed to the inner side wall of the housing 10, with its bottom side connected to the bottom wall of the housing 10 and its front and rear sides connected to the front and rear side walls of the housing 10, specifically by welding. The top of the water-blocking base plate 21 has a second mounting groove 212 that extends laterally (i.e., extends in the front-rear direction). The front and rear sides of the top of the water-blocking base plate 21 both have upwardly extending support arms, each of which has a vertically extending first mounting groove 211, with the openings of the two first mounting grooves 211 facing each other. The two support arms on the water-blocking base plate 21 are also fixedly connected to the front and rear side walls of the housing 10, such as by welding. The water-blocking movable plate 22 is a rectangular plate structure with first folded edges 221 that bend outwards along its front and rear edges. The bending height matches the width of the first mounting groove 211 and the second mounting groove 212. During installation, the front and rear sides of the water-blocking movable plate 22 are inserted into the front and rear first mounting slots 211, and then moved downwards along the first mounting slots 211 until the bottom edge of the water-blocking movable plate 22 is embedded in the second mounting slot 212 of the water-blocking base plate 21. Depending on the site water level requirements, multiple water-blocking movable plates 22 can be stacked vertically. For example, when the water-blocking height needs to be increased, the number of water-blocking movable plates 22 can be two or more. In this case, the front and rear sides of the upper water-blocking movable plate 22 can be inserted into the front and rear first mounting slots 211, and then moved downwards along the first mounting slots 211 until it abuts against the top of the lower water-blocking movable plate 22, and then stacked upwards. The water-blocking movable plates 22 are tightly connected through the cooperation of the first folded edge 221 with the corresponding mounting slot, ensuring structural stability under water flow impact.

[0036] In this embodiment, the water-blocking movable plate 22 of the water-blocking plate assembly is a standardized water-blocking plate of fixed size, that is, the length and width dimensions are fixed values, and the overall height of the water-blocking plate assembly is determined according to the actual on-site measurement. Sealing strips (not shown) can be added between the water-blocking base plate 21 and the water-blocking movable plate 22, as well as between two adjacent water-blocking movable plates 22, to increase sealing. If the inlet and outlet interfaces of the housing 10 are large-diameter pipe outlets, the dimensions of the standardized housing 10 are increased according to the actual situation, while the corresponding reserved slot dimensions of the water-blocking plate assembly can remain unchanged.

[0037] See Figures 3-6The housing 10 also includes a basket grille assembly 3 near the water inlet pipe. The main basket 31 can be made of stainless steel mesh, with vertically extending and outwardly protruding positioning flanges 313 on its front and rear sides. A third mounting groove 14 is provided inside the housing 10 corresponding to the front and rear sides of the main basket 31. Specifically, the housing 10 has two spaced-apart uprights, each with the aforementioned third mounting groove 14, their openings facing each other. The two positioning flanges 313 of the main basket 31 cooperate with the two third mounting grooves 14 to achieve vertical sliding. That is, during installation, after aligning the two positioning flanges 313 of the main basket 31 with the top openings of the two third mounting grooves 14, it can be directly moved down along the third mounting grooves 14 for installation. Similarly, the main basket 31 can also be lifted upwards to remove it. After the main basket 31 is installed, a first inlet 311 is provided on the side facing the water inlet interface 121, allowing water flowing through the water inlet interface 121 to flow into the main basket 31. Two auxiliary baskets 32 are nested inside the main basket 31. A second inlet 320 is provided at the top of each auxiliary basket 32, its height lower than the water inlet interface 121, ensuring that water flows into the auxiliary baskets 32 after entering through the first inlet 311 of the main basket 31. An installation port 312 is provided at the top of the main basket 31, allowing the auxiliary baskets 32 to be removed separately for cleaning when pulled upwards. Specifically, lifting ropes are provided at the top of both the main basket 31 and the auxiliary baskets 32, which can be hung to the top edge of the housing 10 for convenient lifting and cleaning operations during daily maintenance, improving the convenience of maintenance and operation. Both the first inlet 311 of the main basket 31 and the second inlet 320 of the auxiliary basket 32 ​​can be used to pour out filtered impurities.

[0038] In this embodiment, there are two auxiliary baskets 32 arranged side by side. The left and right dimensions of the two auxiliary baskets 32 are slightly smaller than the left and right dimensions of the main basket 31. The total dimensions of the two auxiliary baskets 32 in the front and back direction are slightly smaller than the front and back dimensions of the main basket 31, so that they can be put into the main basket 31.

[0039] The housing 10 includes a main body 11 with an open top and a detachable brim module 13 connected to the open top of the main body 11. The brim module 13 has an operating port 130 for manual operation, which facilitates manual adjustment of the water-blocking plate or cleaning of the filter basket, and also facilitates daily maintenance, improving maintenance efficiency. In this embodiment, the cross-section of the main body of the brim module 13 is basically the same as the cross-section of the main body 11. The brim module 13 and the main body 11 are designed to be detachable, mainly to take into account the different burial depths of the diversion device during construction. The general specifications are in the range of 2 to 4 meters, but the main body of the housing 10 is mostly designed with fixed dimensions. To cope with different depths, the main body 11 and the brim module 13 can be directly connected, or brickwork can be used on the top of the main body 11 (e.g., Figure 7 (The brickwork is set at point a in the attached diagram) and then the brim is spliced ​​together to form a whole.

[0040] The rainwater and sewage separation device in this embodiment also includes a water pump, sensors, and corresponding control circuit modules inside its housing 10. The water pumps are primarily sewage pumps and rainwater pumps, while the sensors are mainly water quality sensors and liquid level sensors. Sensor support columns are pre-installed inside the housing 10 to ensure the sensors are positioned appropriately within the housing 10. A crossbeam can also be installed at a corresponding location inside the housing 10, with a sliding track module on top of the crossbeam. This ensures the rainwater pump outlet pipe is at a suitable installation height and provides stability to the pump during operation, preventing the outlet pipe from shifting due to vibration or falling into the water, causing siphoning and other adverse operating conditions. The outlet pipe is secured to the top of the sliding track module with clamps, the size of which can be adjusted according to the diameter requirements of different water pump outlet pipes. The installation method and operation process of the water pump, sensor and corresponding control circuit module in the housing 10 of the above-mentioned rainwater and sewage separation device can all adopt existing technologies, such as the prior application of the applicant, "An Intelligent Rainwater and Sewage Separation Device" (application number: CN202222353386.7), which discloses this, and will not be repeated here.

[0041] The rainwater and sewage separation device in this embodiment adopts a modular water-blocking plate assembly. This assembly includes a vertically extending water-blocking base plate 21 and a vertically extending movable water-blocking plate 22 located above the base plate 21. At least one movable water-blocking plate 22 is present, and its quantity can be selected for detachable installation on the base plate 21 to change the overall height of the assembly. This modular water-blocking plate assembly is prefabricated and assembled on-site, reducing the civil engineering construction period (shortening the construction period by 60% compared to traditional solutions). After the separation device is installed, if the height of the water-blocking plate needs to be adjusted, the overall height can be quickly raised or lowered by adding or removing the movable water-blocking plate 22, reducing the complexity of secondary construction and meeting the needs of rapid deployment. When the water-blocking plate module malfunctions, it can be replaced and maintained independently; if the water-blocking plate is damaged, only the water-blocking module needs to be disassembled. In a preferred embodiment, the basket grille assembly 3 also adopts a modular design. When the basket grille assembly 3 is clogged, the auxiliary basket 32 ​​can be lifted for cleaning, making subsequent operation and maintenance more flexible and convenient.

[0042] Based on the above embodiments, other embodiments can be obtained by replacing and improving the relevant technical features. For example, only the second mounting groove 212 mentioned above is provided on the water-blocking substrate 21, while the first mounting groove 211 is provided on the front and rear side walls of the housing 10. For example, corresponding uprights are provided on the front and rear side walls of the housing 10, and corresponding first mounting grooves 211 are opened on the uprights. The water-blocking substrate 21 can also be fixed to the housing 10 by welding. As another example, the water-blocking substrate 21 and the side wall of the housing 10 can also be detachably connected, and the first mounting groove 211 extending vertically is directly machined on the inner side of the front and rear side walls of the housing 10. Similar folded edges are also provided on the four perimeters of the water-blocking substrate 21. Like the water-blocking movable plate 22, the front and rear folded edges of the water-blocking substrate 21 are inserted into the first mounting groove 211 of the housing 10 from top to bottom for installation, and removed from bottom to top for disassembly.
