Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, and in particular to a sewage and clean water separation drainage device. Background Technology

[0002] Urban drainage systems are an important part of urban infrastructure, responsible for collecting, transporting, treating and discharging rainwater, domestic sewage and industrial wastewater, ensuring urban flood control and drainage, water environment safety and public health. In order to reduce pollution when water flows out, the water is first discharged to sewage treatment plants for treatment, and then discharged into rivers after the water quality meets the discharge standards.

[0003] However, existing drainage devices cannot separate water flow during actual use, resulting in clean water that can be directly reused or discharged into natural water bodies (such as rainwater, cooling water, and primary drainage after equipment cleaning) being discharged into the sewage treatment plant. This leads to increased sewage treatment costs and reduced water resource utilization, as it cannot reasonably separate clean and sewage flow. Therefore, a clean and sewage separation drainage device is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a clean and dirty water diversion drainage device, which aims to improve the problem in the prior art that it is difficult to accurately divert and treat clean and dirty water when discharging water.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater diversion and drainage device, comprising a diversion pipe, an inlet pipe fixedly connected to the upper surface of the diversion pipe, a fixed box fixedly connected to the bottom surface of the diversion pipe, a diversion column disposed inside the diversion pipe, arc-shaped sealing plates fixedly connected to the bottom surfaces of both sides of the diversion column, multiple electric push rods fixedly connected to the inner wall surface of the right side of the fixed box, a connecting plate fixedly connected to the left end of the multiple electric push rods, the diversion column being hollow inside, a support assembly disposed inside the diversion column, a water quality detection element fixedly connected to the inner wall surface of the inlet pipe, and a stop block fixedly connected above the water quality detection element.

[0008] As a further description of the above technical solution:

[0009] The outer diameter of the arc-shaped sealing plate is the same as the inner diameter of the diversion pipe, and the baffle is fixedly connected to the inner wall of the inlet pipe.

[0010] As a further description of the above technical solution:

[0011] The upper surface of the connecting plate is fixedly connected to the bottom surface of the diversion column, and the connection between the fixing box and the diversion pipe is set in an open shape.

[0012] As a further description of the above technical solution:

[0013] The support assembly includes a fixing plate, which is fixedly connected to the center of the diversion column. Support rods are fixedly connected to both the left and right surfaces of the fixing plate, and the end of the support rod away from the fixing plate is fixedly connected to the inner wall of the diversion column.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a wastewater diversion and drainage device, including a diversion pipe 1. An inlet pipe 2 is fixedly connected to the upper surface of the diversion pipe 1, allowing water to enter the diversion pipe 1 through the inlet pipe 2. A fixing box 3 is fixedly connected to the bottom surface of the diversion pipe 1, with an open connection between the fixing box 3 and the diversion pipe 1. A diversion column 4 is installed inside the diversion pipe 1, inserted into the interior of the diversion pipe 1. When the diversion column 4 is directly below the inlet pipe 2, it seals the connection between the inlet pipe 2 and the diversion pipe 1. When the diversion column 4 moves to the left, it opens the inlet pipe. When the space below the inlet pipe 2 is open, the water can enter the right side of the diverter pipe 1 from the inlet pipe 2 and flow out through the right end of the diverter pipe 1. Similarly, when the diverter column 4 moves to the right, the water can flow out through the left end of the diverter pipe 1. The upper ends of both sides of the diverter column 4 are inclined towards the inlet pipe 2. The inclined surfaces on both sides of the diverter column 4 can guide and limit the flow of water. When the diverter column 4 moves to open the space below the inlet pipe 2, the water enters the interior of the diverter pipe 1 and can flow along the inclined surfaces of the diverter column 4 to the end of the diverter pipe 1, thereby reducing the impact of the water flow on the bottom surface of the diverter pipe 1.

[0032] Reference Figures 2-4 Arc-shaped sealing plates 5 are fixedly connected to the bottom surfaces of both sides of the diversion column 4. The arc-shaped sealing plates 5 are made of ethylene propylene diene monomer (EPDM) rubber. The outer diameter of the arc-shaped sealing plate 5 is the same as the inner diameter of the diversion pipe 1. The arc-shaped sealing plates 5 can seal the opening at the connection between the diversion pipe 1 and the fixed box 3, reducing the possibility of water flowing into the fixed box 3. When the diversion column 4 moves left and right, it will drive the arc-shaped sealing plates 5 to move synchronously. During this process, the arc-shaped sealing plates 5 can ensure the sealing effect at the opening. Multiple electric push rods 6 are fixedly connected to the inner surface of the right side of the fixed box 3. The left side of the multiple electric push rods 6... A connecting plate 7 is fixedly connected to the end. When the multi-section electric push rod 6 is started, it can drive the connecting plate 7 to move linearly in the left and right directions. The upper surface of the connecting plate 7 is fixedly connected to the bottom surface of the diversion column 4. When the multi-section electric push rod 6 is started and drives the connecting plate 7 to move left and right, it will drive the diversion column 4 to move synchronously. A water quality detection component 9 is fixedly connected to the inner wall surface of the inlet pipe 2. The water quality detection component 9 includes a flow meter, a turbidity sensor, a COD sensor, a conductivity sensor, etc., which can detect the flow rate, suspended solids concentration, chemical oxygen demand or ammonia nitrogen concentration, and pH of the water entering the inlet pipe 2, and thus determine whether the water is clean or dirty.

[0033] The flow meter, turbidity sensor, COD sensor, and conductivity sensor in the water quality testing component 9 are connected to the signal conditioning module via shielded wires. The signal conditioning module amplifies, filters, and performs analog-to-digital conversion on the signals output by the sensors. The processed digital signals are then transmitted to the microcontroller via an RS-485 bus. The microcontroller, as the core of the entire control logic, is responsible for receiving, analyzing, and processing the sensor data, and outputting control signals according to the preset control strategy. The microcontroller is connected to the driver of the multi-section electric push rod 6 via a CAN bus, transmitting the control signals to the driver. The driver drives the motor of the multi-section electric push rod 6 to operate according to the received signals, thereby achieving precise control of the position of the diversion column 4. The use of RS-485 bus and CAN bus for signal transmission has the characteristics of long transmission distance and strong anti-interference ability, ensuring stable and reliable signal transmission in complex industrial environments. The threshold values ​​of various water quality parameters are preset in the microcontroller program.

[0034] A baffle 10 is fixedly connected to the top of the water quality testing component 9. The baffle 10 is fixedly connected to the inner wall of the inlet pipe 2. The baffle 10 can shield and protect the top of the water quality testing component 9 to prevent the water flow from directly impacting the water quality testing component 9 when it flows downward, which would affect the service life of the water quality testing component 9. The upper surface of the baffle 10 is inclined downward on the side near the center of the inlet pipe 2. When the water flow reaches the upper surface of the baffle 10, it can quickly slide down along the inclined surface of the baffle 10, including impurities mixed in the water flow.

[0035] The diversion column 4 has a hollow interior and a support assembly 8 inside. The support assembly 8 includes a fixing plate 81, which is fixedly connected to the center of the diversion column 4. Support rods 82 are fixedly connected to both sides of the fixing plate 81. The end of the support rod 82 away from the fixing plate 81 is fixedly connected to the inner wall of the diversion column 4. The fixing plate 81 and the support rods 82 are connected by welding. Both are made of Q345B low alloy high strength structural steel. The hollow design of the diversion column 4 can greatly reduce its weight, while the fixing plate 81 and the support rods 82 can support and limit the interior of the diversion column 4, thereby improving the overall strength of the diversion column 4 and extending its service life.

[0036] Reference Figure 1 and Figure 5A trapezoidal block 11 is fixedly connected to the bottom surface of the connecting plate 7. When the connecting plate 7 moves, it can drive the trapezoidal block 11 to move synchronously. The surfaces of the trapezoidal block 11 and the triangular groove 12 are polished to a surface roughness of less than Ra0.8μm. A triangular groove 12 is provided on the bottom surface of the fixed box 3. The trapezoidal block 11 and the triangular groove 12 are slidably connected inside the box. The fit tolerance between the trapezoidal block 11 and the triangular groove 12 is controlled within ±0.03mm. The cross-section of the triangular groove 12 is triangular, which can guide and limit the movement of the trapezoidal block 11, so that the trapezoidal block 11 can only move linearly in the left and right directions inside the triangular groove 12. This can improve the stability of the connecting plate 7 during movement. At the same time, the trapezoidal structure of the trapezoidal block 11 leaves a distance between its bottom surface and the bottom end of the triangular groove 12, allowing it to enter the fixed box 3. The internal water flow can flow through the bottom of the trapezoidal block 11 to the left side of the triangular groove 12. A connecting pipe 13 is fixedly connected to the left side surface of the fixing box 3. The connection position of the connecting pipe 13 and the fixing box 3 is adapted to the bottom position of the triangular groove 12. A water pump 14 is fixedly connected to the outside of the connecting pipe 13. The water pump 14 is a stainless steel centrifugal sewage pump. When the water pump 14 starts, it can draw water from inside the triangular groove 12 through the connecting pipe 13. An inclined pipe 15 is fixedly connected to the upper end of the connecting pipe 13. The end of the inclined pipe 15 away from the connecting pipe 13 is connected to the left side surface of the inlet pipe 2. The right end of the inclined pipe 15 is inclined downward. When the water pump 14 starts to draw liquid from inside the triangular groove 12, it can be discharged back into the inlet pipe 2 through the inclined pipe 15. At the same time, the inclined setting of the inclined pipe 15 can prevent water from entering the inclined pipe 15 when it enters the inlet pipe 2 from above.

[0037] Working principle: Water enters through inlet pipe 2. Water quality detection components 9 (flow meter, turbidity sensor, COD sensor, etc.) monitor water quality parameters in real time (such as suspended solids concentration, chemical oxygen demand, pH value, etc.). Baffle 10 protects the sensor from direct water flow impact and guides impurities to pass quickly. If the detected water quality is clean (such as rainwater or cooling water), the system controls the multi-section electric push rod 6 to push the diversion column 4 to the left, opening the right-side channel. Water flows out from the right end of diversion pipe 1 (entering a natural water body or reuse system). If... When the water quality is sewage (such as high COD, high turbidity), the multi-section electric push rod 6 pulls the diversion column 4 to the right, opening the left channel. The water flows out from the left end of the diversion pipe 1 (entering the sewage treatment system). During this process, the arc-shaped sealing plate 5 always fits against the inner wall of the diversion pipe 1 to ensure that the opening of the fixing box 3 is sealed when the diversion column 4 moves, preventing water from seeping in. A small amount of water that seeps into the fixing box 3 flows to the bottom through the gap between the trapezoidal block 11 and the triangular groove 12, and is pumped back to the inlet pipe 2 by the water pump 14 through the connecting pipe 13 and the inclined pipe 15, thus achieving self-cleaning.

[0038] The hollow design of the diversion column 4 reduces weight, and the internal support component 8 (fixed plate 81 + support rod 82) enhances compressive strength. The trapezoidal block 11 slides in the triangular groove 12, restricting the connecting plate 7 to move only horizontally and preventing it from tilting and getting stuck.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
