Description

A prefabricated underground rainwater and muddy water mixing and diversion device Technical Field

[0001] This invention relates to the field of building renovation, protection, and drainage technology, and more specifically, to a prefabricated underground rainwater and muddy water mixing and diversion device. Background Technology

[0002] With increasing environmental awareness, greater emphasis is being placed on urban environmental protection and sustainable resource utilization during the construction of modern cities. For example, separate stormwater and sewage drainage systems are being adopted to separate rainwater from domestic sewage. This allows for centralized sewage treatment to reduce environmental pollution and rainwater recycling for reuse. However, in most old urban areas, due to various factors, mixed stormwater and sewage drainage systems are still commonly used, which is detrimental to the protection of the natural environment and the health of residents.

[0003] Chinese utility model patent CN212175983U discloses an underground rainwater and mud-water separation pipe network structure, relating to the field of sewage treatment technology. It includes a main drainage pipe, a rainwater pipe, and a sewage pipe. The main drainage pipe has a treatment tank at one end, connected to the rainwater pipe at its upper end, and a diversion component at its lower end, connected to the sewage pipe. The sewage pipe has a mud-water separation unit, including a transfer tank, a stirring paddle, and a stirring motor. The transfer tank has a conveying pipe, and the conveying pipe has a separation tank. A sludge pipe assembly is located between the separation tanks. The main drainage pipe collects sewage. During periods of heavy rainfall, the flow rate is high and the water quality is good. The water is diverted to the rainwater pipe for discharge through the diversion component. During periods of no rainfall, the sewage is transported to the sewage pipe via the diversion component, treated by the mud-water separation unit, and then fed into the transfer tank. The stirring motor and stirring paddle mix the mud and water and transport it to the separation tank for separation of sludge and sewage. The sludge enters the sludge pipe assembly, preventing sludge deposition and pipe blockage, while simultaneously separating rainwater and sewage.

[0004] The aforementioned devices are difficult to support during the actual construction process. During the renovation of old buildings and streets with separate rainwater and sewage systems, construction workers need to excavate trenches and install rainwater and sewage drainage pipes inside the trenches. During the trench excavation process, due to the poor load-bearing capacity of the old buildings, there is a risk of building imbalance and collapse, which makes it inconvenient to carry out the renovation work. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, this invention provides a prefabricated underground rainwater and muddy water mixing and diversion device. This device can be connected to the walls of old buildings via pre-drilled mounting holes and bolts, providing reliable support. Its reasonable structural design effectively separates rainwater and muddy water. While providing oblique support to the main structure of the old building using a support mechanism, it also provides protection for construction workers installing pipes.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0009] The support mechanism includes a fixed groove plate, a top plate, and a grounding plate. The top plate is located below the fixed groove plate. A pressure-bearing block is provided inside the fixed groove plate. A groove seat is provided inside the grounding plate. The pressure-bearing block and the groove seat are connected by a support component. The top plate is located above the bottom plate. The top plate and the bottom plate are connected by a vertical support component. A lower pressure plate is connected to one side of the grounding plate. The lower pressure plate is connected to the side wall of the trench slope protection body.

[0010] A pointed rod is provided at the lower part of the grounding plate, with the tip of the pointed rod pointing downwards and the top of the pointed rod connected to the lower surface of the grounding plate.

[0011] The support assembly includes a first docking cylinder rod, a second docking cylinder rod, and a docking screw rod.

One end of the first docking cylinder rod is hinged to the pressure block, and one end of the second docking cylinder rod is hinged to the groove seat. A handle rod is provided on the docking screw rod.

[0012] The vertical support assembly includes a lower support rod, a cylindrical column, and an upper support rod. A lower threaded cylinder is provided on the base plate, and an upper threaded cylinder is provided at the lower part of the top plate. A first screw is provided at the lower end of the lower support rod, and the first screw is connected to the lower threaded cylinder. The top of the lower support rod is fixedly connected to the cylindrical column. The upper support rod is slidably disposed inside the cylindrical column. A second screw is provided at the upper part of the upper support rod, and the upper part of the second screw is connected to the upper threaded cylinder. A brake knob is provided on the cylindrical column.

[0013] The upper part of the mixing pipe is provided with an installation port, and a filter plate is provided inside the installation port. The separation box is provided with a mud baffle plate, and a cleaning component is provided on one side of the mud baffle plate.

[0014] The cleaning component includes a servo motor and a connecting shaft. The servo motor is mounted on the separation box, and the output shaft of the servo motor is connected to the connecting shaft. The connecting shaft extends into the separation box and is located on one side of the mud barrier.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] When the separated rainwater is transported to the delivery pipe through the drainage pipe, the delivery pipe is connected to the pressure plate by a lifting and pressing assembly. Furthermore, when the rainwater enters the delivery pipe, gravity exerts a downward force on the lifting rope. A guide wheel further alters the direction of this force, facilitating a downward force on the pressure plate through the end of the lifting rope. This allows the tip rod to be inserted deeper into the soil, strengthening the support structure and enhancing the device's stability. The structure is ergonomically designed. After installation, workers can backfill the trench slope protection. The vertical support components in the structure can be disassembled and reassembled for easy reuse; they can be connected to the old building wall via pre-drilled mounting holes and bolts; then, the bearing block is connected to the fixing groove plate via connecting bolts; and the floor is fixed by inserting the tip rod into the soil. Furthermore, by utilizing the characteristic that the two ends of the connecting screw rod are threaded to the end screw holes of the first and second connecting cylinder rods respectively, the support components can be installed, which facilitates the use of the support mechanism to provide oblique support for the main body of the old building and provides protection for construction workers to install pipelines.

[0039] After installing the trench slope protection body 202, the diversion mechanism 300 and the installation mechanism 400 are laid. Further, during rainy weather, rainwater enters the mixing pipe 302 through the filter screen 303, and then enters the separation box 304 through the guide pipe 301. The filter screen 303 effectively intercepts larger mud clumps and debris in the rainwater. The separation box 304 is equipped with a mud-blocking plate 305, which separates rainwater and muddy water. The separated muddy water is then transported by the pump 312 to… In the sewage pipe 311, the separated rainwater is discharged through the drain pipe 401 and the conveying pipe 402. By setting a cleaning component inside the separation box 304, when there is a lot of sludge attached to the surface of the mud barrier 305, the connecting shaft 307 and the rubber ball 310 can be rotated by driving the servo motor 306. The flexible rod 309 facilitates the use of the rubber ball 310 to knock on one side of the mud barrier 305, which is convenient for removing the sludge attached to its surface and improving the separation efficiency of the mud barrier 305.

[0041] When the separated rainwater is transported from the drainage pipe 401 to the conveying pipe 402, the conveying pipe 402 is connected to the lower pressure plate 105 by setting up a lifting and pressing assembly. Furthermore, when the rainwater enters the conveying pipe 402, under the action of gravity, the conveying pipe 402 applies a downward force to the lifting rope 404. Further, by setting up a guide wheel 406, the direction of the force is changed, which makes it easier to apply a downward force to the lower pressure plate 105 through the end of the lifting rope 404. This facilitates the tip rod 106 to be inserted deeper into the soil layer, strengthening the support of the support mechanism 100 for the device. The structural design is user-friendly. After installation, the workers fill the trench slope protection body 202. The vertical support components in the trench mechanism 200 can be disassembled and reassembled for easy reuse.
