Description

Technical Field

[0001] This application relates to the technical field of water conservancy engineering, and in particular to a low-carbon wastewater treatment plant water control and diversion device. Background Technology

[0002] With the continuous development of my country's economy, infrastructure projects that drive economic development are becoming increasingly important. The construction of water conservancy projects has received a lot of attention, and sewage treatment plants are an important part of water conservancy projects. Sewage treatment plants are generally treatment stations for urban sewage. Urban sewage is discharged to sewage treatment plants through sewage pipes for treatment, and the requirements for low-carbon and environmentally friendly sewage treatment plants are becoming increasingly stringent.

[0003] In cities, domestic sewage and rainwater easily mix and enter sewage pipes. Therefore, in order to effectively separate rainwater and sewage, diversion devices have been developed. During the dry season, the diversion device sends sewage to sewage treatment plants for treatment. During the rainy season, the diversion device continues to send some water to sewage treatment plants for treatment, while the remaining water is transported to rivers through the municipal water network. However, sewage and rainwater contain a lot of impurities, which settle and accumulate during their flow into sewage treatment plants or municipal water networks, thus reducing the effectiveness of rainwater and sewage discharge. At the same time, these impurities can also easily enter sewage treatment plants, increasing the treatment pressure on the plants and further reducing the effectiveness of rainwater and sewage treatment. Summary of the Invention

[0004] To improve the treatment efficiency of rainwater and sewage, this application provides a low-carbon sewage treatment plant water control and diversion device.

[0005] This application provides a low-carbon wastewater treatment plant water control and diversion device, which adopts the following technical solution:

[0006] A low-carbon wastewater treatment plant water control and diversion device includes a pool body, an inlet pipe installed on the pool body for conveying water, a sewage pipe installed on the pool body and connected to the wastewater treatment plant, and a drainage pipe connected to the municipal water network. The pool body is equipped with a decontamination mechanism for removing impurities from the water. The decontamination mechanism includes:

[0007] A debris removal frame is provided on the pool body and has multiple debris removal holes for water supply.

[0008] The inlet pipe is installed on the pool body and is equipped with a partition plate that divides the inlet pipe into an inlet chamber and an outlet chamber. Water in the inlet pipe flows into the inlet chamber and the outlet chamber. Water in the inlet chamber flows into the impurity removal frame and water in the outlet chamber flows into the pool body. A rotating rod is rotatably installed on the partition plate with its two ends located in the inlet chamber and the outlet chamber, respectively.

[0009] A filter screen is installed on the inlet pipe and is used to filter the water entering the outlet chamber;

[0010] Multiple levers are mounted on a rotating rod and located inside the liquid outlet chamber. Water entering the liquid outlet chamber drives the multiple levers to rotate.

[0011] A cutting blade is mounted on a rotating rod and located within the liquid inlet chamber, and is used to chop up impurities.

[0012] By adopting the above technical solution, water and impurities in the inlet pipe enter the inlet and outlet chambers. Water and impurities in the outlet chamber are filtered through a filter screen, with impurities remaining on the screen. The water continues to flow downwards, impacting the rotating paddle. The paddle's rotation drives the rotating rod and cutting blades to rotate. Water and impurities entering the inlet chamber are then cut by the cutting blades, which collect the cut impurities in a collection frame. The water then flows through the collection frame into the tank. This process filters impurities in the water, reducing the amount of impurities and lowering the probability of them entering the sewage and drainage pipes, thus improving the treatment effect on rainwater and sewage.

[0013] Furthermore, the cutting blades cut through impurities, thereby improving the collection effect of the impurity removal frame. At the same time, the water entering the outlet chamber is filtered, and the filtered water impacts the rotating blades, thereby reducing the probability of impurities clogging the outlet chamber. This improves the pushing effect of the water on the blades and enhances the cutting effect on impurities. Moreover, the water flowing directly into the pool through the blades reduces the probability of water flowing into the impurity removal frame and reducing its collection effect, thus further improving the removal effect of impurities in the water and further improving the treatment effect of rainwater and sewage.

[0014] Meanwhile, impurities are broken down and removed by water impact force, eliminating the need for an additional power mechanism. Moreover, the contact with water increases the difficulty of setting up a power mechanism. Therefore, this application saves energy, thereby meeting the requirements of low-carbon and environmentally friendly operation of wastewater treatment plants, and also improving the convenience of setting up impurity removal mechanisms.

[0015] Optionally, a guide assembly is provided on the liquid outlet chamber, the guide assembly comprising:

[0016] A guide plate is disposed on the liquid outlet chamber and above the lever, and is used to guide water to the same side of the rotating rod.

[0017] An arc-shaped guide plate is disposed on the liquid outlet chamber and located below the rotating rod. A water passage hole is provided at the lowest point of the arc-shaped guide plate for water supply. Two adjacent paddles cooperate with the arc-shaped guide plate to form independent water inlet spaces.

[0018] By adopting the above technical solution, the guide plate directs the water to the same side as the rotating rod, thus reducing the water flow area from large to small, thereby accelerating the water flow rate and increasing the water impact force. Then, the water enters the water inlet space to drive the lever to rotate, thereby reducing the probability that the water will not contact the lever and thus reduce the driving force on the lever. Finally, the water is output through the water outlet, thereby improving the driving effect of the water on the lever, thereby improving the cutting effect on impurities, and thus improving the treatment effect of rainwater and sewage.

[0019] Optionally, a receiving cover is provided on the inner side wall of the pool and below the inlet of the water inlet pipe. The receiving cover is provided with a receiving pipe connected to the sewage pipe. The receiving cover is located between the inlet of the water inlet pipe and the impurity removal mechanism. During the dry season, sewage in the inlet pipe flows into the receiving cover. During the rainy season, the rainwater and sewage in the inlet pipe mix and the force increases, causing the water to flow to the impurity removal mechanism for impurity removal.

[0020] By adopting the above technical solution, the wastewater contains fewer impurities and generally contains more viscous substances such as grease. This type of wastewater does not need to enter the impurity removal mechanism for removal. Moreover, if this type of wastewater enters the impurity removal mechanism, it will adhere to the impurity removal mechanism, reducing its efficiency and effectiveness. Therefore, during the dry season, the inlet pipe is full of wastewater with a small volume. When the wastewater in the inlet pipe flows to the contact point with the pool body, it will flow down the side wall of the pool body into the receiving hood. Then, the wastewater is discharged to the wastewater treatment plant for treatment through the receiving pipe and the sewage discharge pipe. This reduces the probability of wastewater entering the impurity removal mechanism and reducing its efficiency. It also reduces the probability of wastewater flowing into the pool body and remaining there without being treated, thus further improving the treatment effect of rainwater and wastewater.

[0021] During the rainy season, the volume of water increases significantly after rainwater and sewage mix. As the rainwater and sewage exit the inlet pipe, the increased water impact force propels them forward, directing them to the impurity removal mechanism for purification. Furthermore, the sewage is diluted by the rainwater, reducing the content of viscous substances such as grease, which further lowers the probability of the impurity removal efficiency being reduced. This further enhances the removal of impurities from the water and improves the overall treatment effect of rainwater and sewage.

[0022] Optionally, the pool body is provided with a water control mechanism, the control mechanism including:

[0023] A control pipe is installed on the pool body and connected to the sewage pipe;

[0024] A gate, which is slidably mounted on the pool body and forms an overflow space between its top and the inner top wall of the pool body, the overflow space being located above the control pipe and connected to the drain pipe;

[0025] A control component, which is disposed on a control pipe and is used to adjust the size of the space through which water passes within the control pipe;

[0026] A drive assembly is disposed on the pool body and is used to drive the gate to move.

[0027] By adopting the above technical solution, during the dry season, sewage flows into the pool, and then the sewage in the pool enters the sewage treatment plant for treatment through the control pipe and the sewage discharge pipe. During the rainy season, the rainwater and sewage, which initially contain a large number of impurities, are cleaned by the impurity removal mechanism and then continue to enter the sewage treatment plant for treatment through the control pipe and the sewage discharge pipe. As the rainwater increases, it accumulates in the pool, causing the water to shift above the control pipe. The control component controls the size of the control pipe to control the amount of water entering the sewage treatment plant. Impurities and some pollutants in the water form sediment in the pool. The sedimented water overflows into the drainage pipe through the overflow space and is finally discharged into the municipal water network through the drainage pipe. In addition, the drive component activates the control gate position, which further improves the discharge effect of sewage and rainwater, thus improving the treatment effect of rainwater and sewage.

[0028] Optionally, the control component includes:

[0029] Two annular hoses are disposed on the inner wall of the control pipe and are made of soft material, and cooperate with the inner wall of the control pipe to form an annular control cavity. The two annular hoses cooperate to form a flow space through which water is supplied.

[0030] An inlet pipe and an outlet pipe are provided, which are disposed on a control pipe and communicate with a control cavity. The pool body is provided with an input mechanism that communicates with the inlet pipe and the outlet pipe and is used to control the input or output of the medium into or out of the control cavity.

[0031] By adopting the above technical solution, the input mechanism controls the medium to enter the control chamber through the inlet pipe. The medium pushes the annular hose to expand, thereby reducing the size of the flow space. The input mechanism controls the output of the medium in the control chamber and the water pressure to cause the annular hose to contract, thereby increasing the size of the flow space. This adjusts the size of the flow space, thereby regulating the amount of water entering the sewage treatment plant, thus improving the treatment effect of rainwater and sewage.

[0032] Sewage pipes are relatively large, so the valves used are also large, making the installation and control of gates inconvenient. Moreover, the water flow is blocked at the gate, resulting in extremely high pressure on the gate, which makes the gate prone to damage and reduces the water control effect. This application only requires connecting the two ends of the control pipe with flanges, and then controlling the water volume through the combined action of the control medium and water flushing pressure, thus improving the convenience and accuracy of water volume control.

[0033] When the connection between the annular hose and the control pipe expands, it forms an inclined guide surface, which buffers the water and reduces the impact of water pressure on the annular hose, thereby increasing the life of the annular hose and improving the water control effect.

[0034] Optionally, the input mechanism includes:

[0035] A storage box, which is mounted on the pool body;

[0036] A movable piston is slidably disposed inside the storage box and cooperates with the inner side wall of the storage box to form a storage space for gas storage;

[0037] An electric actuator, which is mounted on the storage tank and connected to a movable piston;

[0038] The delivery pipe and the recovery pipe are installed on the storage box and connected to the storage space and respectively connected to the inlet pipe and the outlet pipe. The outlet pipe is equipped with a delivery check valve that allows gas to move through the delivery pipe to the inlet pipe, and the outlet pipe is equipped with a recovery check valve that allows gas to enter the storage space through the recovery pipe.

[0039] A water level detector is installed inside the pool and is used to detect the water level inside the pool and is electrically connected to an electric actuator.

[0040] By adopting the above technical solution, the water level detector detects the water level in the pool. The water level detector controls the electric actuator to start and drive the moving piston to move. The moving piston compresses the gas in the storage space and enters the control chamber through the delivery check valve, output pipe and inlet pipe. The gas pushes the annular hose to expand. When it is necessary to shrink the annular hose, the electric actuator starts and drives the moving piston to move back. The movement of the moving piston causes the gas in the control chamber to enter the storage space through the output pipe, recovery check valve and recovery pipe, thereby realizing the adjustment of the size of the flow space.

[0041] Optionally, the two annular hoses are provided with annular protrusions and slots that engage with the protrusions on the sidewalls opposite to the control cavity, and multiple protrusions and slots are provided at intervals.

[0042] By adopting the above technical solution, when the two annular hoses approach each other and press together to close the flow space, the convex ridge is snapped into the slot, thereby improving the water blocking effect, reducing the probability of water passing through the flow space due to excessive impact force, further improving the water diversion effect, and improving the treatment effect of rainwater and sewage.

[0043] Optionally, the gate and the pool body cooperate to form a drainage space communicating with the drain pipe, and the gate is provided with an anti-backflow component, which includes:

[0044] A baffle plate is slidably disposed on the side wall of the gate near the drainage space and is used to block the overflow space;

[0045] An airbag is disposed on a baffle plate and suspended on the water surface within the drainage space.

[0046] By adopting the above technical solution, the backflow in the drainage pipe flows back into the drainage space, causing the water level in the drainage space to rise. The rise in water level causes the airbag to move upward, which in turn causes the baffle plate to move upward and block the overflow space, thereby reducing the probability of river water flowing back into the pool and further improving the treatment effect of rainwater and sewage.

[0047] Optionally, a receiving groove is formed on the bottom wall of the pool, and a cleaning mechanism is provided on the pool body, the cleaning mechanism including:

[0048] A filter plate, wherein the filter plate is disposed within a receiving groove;

[0049] A sewage pump is installed on the upper surface of the filter plate and has a sewage outlet pipe extending above the impurity removal frame;

[0050] A cleaning pump is disposed within a receiving tank and located below the filter plate;

[0051] A cleaning pipe, which is installed on the pool body and connected to a cleaning pump;

[0052] A sealing ring, which is rotatably mounted on the cleaning pipe and used to seal the opening of the cleaning pipe;

[0053] A cleaning plate is mounted on a sealing ring and has multiple rotating grooves that communicate with the inside of a cleaning pipe. Water is sprayed from the cleaning pipe onto the rotating grooves to drive the cleaning plate to rotate and clean the pool.

[0054] By adopting the above technical solution, a significant amount of impurities will settle on the bottom wall of the pool during water storage. Therefore, during the dry season when the water volume in the pool is low, the sewage pump starts, and the water and impurities in the receiving tank are discharged into the impurity removal frame through the sewage pipe. The water flows into the pool through the impurity removal frame, while the impurities remain in the frame. At the same time, the cleaning pump starts, and the water filtered by the cleaning plate enters the cleaning pump. Then, the water enters the cleaning pipe, where the sealing ring blocks the water, and the water sprays out and impacts the rotating tank, causing the cleaning plate to rotate. Thus, the sprayed water forms a ring to clean the bottom wall of the pool. Simultaneously, the cleaning plate agitates the water on the bottom wall, causing the impurities settled on the bottom wall to rise. As the water in the receiving tank decreases and the tank position becomes lower, the water and impurities on the bottom wall of the pool enter the receiving tank. Then, the impurities and water enter the impurity removal frame through the sewage pipe for cleaning. This cycle is repeated to clean the bottom wall of the pool, thereby improving the treatment effect of rainwater and sewage.

[0055] Optionally, the filter screen is tilted and used to guide impurities into the liquid inlet chamber, and a support frame is provided on the pool body, with the impurity removal frame snapped onto the support frame.

[0056] By adopting the above technical solution, impurities remain on the filter plate. Subsequently, water impacts the filter plate, causing the impurities to move to the inlet chamber for agitation, thereby accelerating the rate at which water passes through the filter plate and further improving the removal effect of impurities in the water. Before the rainy season, staff can remove the impurity removal frame in advance for cleaning. After cleaning, the frame is snapped onto the support frame, further improving the removal effect of impurities and thus enhancing the treatment effect of rainwater and sewage.

[0057] In summary, this application includes at least one of the following beneficial technical effects:

[0058] Water and impurities enter the inlet and outlet chambers through the inlet pipe. In the outlet chamber, the water is filtered through a filter screen, which drives a rotating disc. This disc rotates the cutting blade, which cuts the impurities in the outlet chamber. The cut impurities fall into a collection frame for disposal, while the water passes through the collection frame and flows into the tank. This process filters impurities from the water, reducing their quantity and the probability of them entering the sewage and drainage pipes, thus improving the treatment efficiency of rainwater and wastewater.

[0066] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0067] This application discloses a low-carbon wastewater treatment plant water control and diversion device.

[0068] The water level detector 76 in this application is model MIK-P260.

[0069] Reference Figure 1 The low-carbon wastewater treatment plant water control and diversion device includes a sealed pool body 1, an inlet pipe 11 fixedly installed on the side wall of the pool body 1 and connected to the interior of the pool body 1, and the inlet pipe 11 is located near the top of the pool body 1 and is used to transport water into the pool body 1; the pool body 1 is provided with a sewage pipe 12 connected to the wastewater treatment plant and a drainage pipe 13 connected to the municipal water pipe network, and the sewage pipe 12 is located near the bottom of the pool body 1 and below the inlet pipe 11, while the drainage pipe 13 is located above the sewage pipe 12 and below the inlet pipe 11; the pool body 1 is provided with a decontamination mechanism 2 for removing impurities from the water, and the pool body 1 is also provided with a water control mechanism 5.

[0070] Reference Figure 1 and Figure 2 The impurity removal mechanism 2 includes an impurity removal frame 21 and an inlet pipe 22. A support frame 14 is fixedly installed on the inner side wall of the pool body 1 near the inlet pipe 11 and below the inlet pipe 11. The support frame 14 is a frame structure, and a snap-fit ​​groove is opened on the upper surface of the support frame 14. A water passage hole for water supply is opened on the bottom of the snap-fit ​​groove. The bottom end of the impurity removal frame 21 is snap-fitted onto the snap-fit ​​groove, and multiple impurity removal holes for water supply are opened on the side wall and inner bottom wall of the impurity removal frame 21.

[0071] Reference Figure 1 and Figure 2 A mounting rod 15 extending vertically above the impurity removal frame 21 is fixedly installed on the upper surface of the support frame 14. The liquid inlet pipe 22 is fixedly installed on the top of the mounting rod 15, and the liquid inlet pipe 22 is located below the water inlet pipe 11 and receives the water flowing out of the water inlet pipe 11. The liquid inlet pipe 22 is vertical and has a square cross-section. At the same time, a flow guide hood 26 is fixedly installed on the top of the liquid inlet pipe 22. The flow guide hood 26 is frustum-shaped and the cross-sectional area of ​​the top end is larger than that of the bottom end. The flow guide hood 26 is used to guide the water in the water inlet pipe 11 into the liquid inlet pipe 22.

[0072] Reference Figure 1 and Figure 2 A vertical partition plate 27 is fixedly installed on the inner wall of the inlet pipe 22, and the partition plate 27 divides the inlet pipe 22 into an independent inlet chamber 221 and an outlet chamber 222. The inlet chamber 221 is located on the side of the outlet chamber 222 closer to the inlet pipe 11, and the inlet chamber 221 is located directly above the impurity removal frame 21. Therefore, water and impurities in the inlet chamber 221 can enter the impurity removal frame 21, while the outlet chamber 222 is located on the side of the impurity removal frame 21 away from the inlet pipe 11. Therefore, water in the outlet chamber 222 flows into the pool body 1. A rotating rod 28 is horizontally rotatably installed on the partition plate 27, with its two ends located in the inlet chamber 221 and the outlet chamber 222 respectively.

[0073] Reference Figure 2 and Figure 3 The impurity removal mechanism 2 also includes a filter screen 23, multiple paddles 24 and a cutting blade 25. The filter screen 23 is fixedly installed on the inner wall of the inlet pipe 22, and the filter screen 23 is located directly above the outlet chamber 222 and completely blocks the outlet chamber 222. At the same time, one end of the filter screen 23 extends into the inlet chamber 221, and the filter screen 23 is in an inclined state, with the height of the end near the inlet chamber 221 being lower than the height of the end away from the inlet chamber 221. The filter screen 23 filters the water entering the outlet chamber 222, and impurities remain on the inclined filter screen 23. At the same time, the impurities can fall into the inlet chamber 221 under the subsequent water impact.

[0074] Reference Figure 2 and Figure 3 Multiple levers 24 are fixedly installed on the rotating rod 28, and the levers 24 are located in the liquid outlet chamber 222. The multiple levers 24 are arranged in a circular array around the axis of the rotating rod 28. The cutting blades 25 are fixedly installed on the rotating rod 28, and the cutting blades 25 are located in the liquid inlet chamber 221. The cutting blades 25 are arranged in a circular array around the axis of the rotating rod 28. Water in the water inlet pipe 11 is guided to the liquid inlet chamber 221 and the liquid outlet chamber 222 through the diversion cover 26. After the water is filtered through the filter screen 23, it enters the liquid outlet chamber 222. The water impacts the levers 24 and causes them to rotate. Then the water flows into the pool body 1. Water and impurities enter the liquid inlet chamber 221. The rotation of the levers 24 drives the cutting blades 25 to rotate and crush the impurities. The crushed impurities and water move to the impurity removal frame 21. The impurities remain in the impurity removal frame 21, while the water flows into the pool body 1 through the impurity removal frame 21.

[0075] Reference Figure 2 and Figure 3 A guide assembly 3 is provided on the liquid outlet chamber 222. The guide assembly 3 includes a guide plate 31 and an arc-shaped guide plate 32. The guide plate 31 is fixedly installed on the side wall of the liquid outlet chamber 222 located on one side of the rotating rod 28. The guide plate 31 is located above the lever 24 and extends downward at an angle to the other side of the rotating rod 28. At the same time, the guide plate 31 blocks the water entering the liquid outlet chamber 222, so that all the water flows to the same side of the rotating rod 28 and then flows downward. The arc-shaped guide plate 32 is fixedly installed on the liquid outlet chamber 222. On the side wall, the arc-shaped guide plate 32 is semi-circular and its axis coincides with the axis of the rotating rod 28. At the same time, the arc-shaped guide plate 32 is located below the rotating rod 28, and multiple paddles 24 can contact the arc-shaped guide plate 32 during rotation. Therefore, two adjacent paddles 24, the upper surface of the arc-shaped guide plate 32 and the side wall of the rotating rod 28 cooperate to form multiple independent water inlet spaces 33. The lowest point of the arc-shaped guide plate 32 is provided with a water passage hole 34 that communicates with the water inlet space 33, and the water passage hole 34 is used for water supply.

[0076] Reference Figure 3Water enters multiple independent water inlet spaces 33 under the action of the guide plate 31. The water pushes the paddle 24 to rotate, thereby driving the rotating rod 28 to rotate. This reduces the probability that the water will not come into contact with the paddle 24, thus improving the pushing effect of the water on the paddle 24.

[0077] Reference Figure 1 and Figure 2 A receiving cover 41 is fixedly installed on the inner wall of the pool body 1 between the liquid inlet pipe 22 and the water inlet pipe 11. The receiving cover 41 is located below the water inlet pipe 11. The side wall of the receiving cover 41 near the pool body 1 is open. A receiving pipe 42 connected to the sewage pipe 12 is fixedly installed on the lower surface of the receiving cover 41. The receiving pipe 42 includes a first vertical section 43, a horizontal section 44 and a second vertical section 45 connected together in sequence. The first vertical section 43 is fixedly installed on the lower surface of the receiving cover 41 and is vertical. The horizontal section 44 extends horizontally out of the pool body 1 near the sewage pipe 12. The second vertical section 45 is vertically downward and fixedly connected to the highest point of the outer wall of the sewage pipe 12.

[0078] Reference Figure 1 and Figure 2 During the dry season, the inlet pipe 11 contains only sewage, which is relatively small in volume and contains a lot of oily and sticky substances. The sewage flows down the side wall of the pool 1 into the receiving hood 41, and then flows through the first vertical section 43, the horizontal section 44 and the second vertical section 45 to the sewage discharge pipe 12. Finally, the sewage is transferred to the sewage treatment plant for treatment. During the rainy season, the inlet pipe 11 is mixed with sewage and rainwater, which increases the water volume and the force of the sewage and rainwater. This causes the sewage, rainwater and impurities to move forward as they leave the inlet pipe 11 and move into the liquid inlet pipe 22 for impurity removal treatment, thereby improving the impurity removal effect of the impurity removal mechanism 2 on the impurities in the rainwater and sewage.

[0079] Reference Figure 1 and Figure 2 A sealing plate 19 is fixedly installed on the inner wall of the pool body 1 near the sewage pipe 12, and the sealing plate 19 divides the pool body 1 into two independent spaces. The space near the sewage pipe 12 is a storage space. The control mechanism 5 includes a control pipe 51 and a control component 6. The control pipe 51 is fixedly installed on the outer wall of the sealing plate 19, and the control pipe 51 is located below the water inlet pipe 11 and communicates with the inside of the pool body 1. At the same time, the control pipe 51 is located in the storage space. The end of the sewage pipe 12 away from the sewage treatment plant passes through the pool body 1 and extends into the storage space, and is fixedly connected to the end of the control pipe 51 away from the sealing plate 19. The axes of the sewage pipe 12 and the control pipe 51 coincide.

[0080] Reference Figure 2 and Figure 4The control component 6 is mounted on the control pipe 51 and is used to adjust the space through which water passes within the control pipe 51. The control component 6 includes two annular hoses 61, an inlet pipe 62, and an outlet pipe 63. The two annular hoses 61 have a semi-circular cross-section and are fixedly mounted on the inner wall of the control pipe 51. The two annular hoses 61 are integrally formed together to form the entire pipe body. The two annular hoses 61 and the inner wall of the control pipe 51 cooperate to form a circular control cavity 64. At the same time, the two annular hoses 61 are both made of soft material, such as plastic. The two annular hoses 61 cooperate to form a flow space 65 for water supply. The axis of the two annular hoses 61 coincides with the axis of the control pipe 51. Both ends of the two annular hoses 61 have inclined guide surfaces that buffer the water.

[0081] Reference Figure 1 and Figure 4 Both the inlet pipe 62 and the outlet pipe 63 are fixedly installed on the outer wall of the control pipe 51 and are connected to the control cavity 64. An input mechanism 7 is also provided on the tank body 1. The input mechanism 7 is connected to the inlet pipe 62 and the outlet pipe 63 and is used to control the input or output of the medium into or out of the control cavity 64. The medium can be an inert gas, such as helium. When the input mechanism 7 is activated, helium is introduced through the inlet pipe 62. The helium pushes the annular hose 61 to expand, thereby reducing the size of the flow space 65. When it is necessary to increase the flow space 65, the control mechanism 5 absorbs the helium in the control cavity 64. The annular hose 61 moves back under the action of the rebound force and the water pressure through the flow space 65, thereby increasing the size of the flow space 65. This is used to adjust the size of the flow space 65, thus realizing the regulation of the water flow rate entering the sewage treatment plant.

[0082] Reference Figure 4 Two annular hoses 61 have protruding ribs 66 and slots 67 on their opposite sidewalls, located away from the control cavity 64. The protruding ribs 66 are semi-annular and can engage with the slots 67. Multiple protruding ribs 66 and slots 67 are spaced apart along the axis of the annular hoses 61. When the opposite sidewalls of the two annular hoses 61 are pressed together and the flow space 65 becomes zero, the protruding ribs 66 are engaged and positioned on the slots 67 to reduce the probability of water continuing to flow under impact.

[0083] Reference Figure 1 and Figure 4 The input mechanism 7 includes a storage tank 71, a moving piston 72, an electric actuator 73, an output pipe 74 and a recovery pipe 75, and a water level detector 76. The storage tank 71 is fixedly installed on the upper surface of the pool body 1. The moving piston 72 is vertically slidably installed on the inner wall of the storage tank 71, and the lower surface of the moving piston 72 and the inner wall of the storage tank 71 cooperate to form a storage space, which is used to store helium.

[0084] Reference Figure 1 and Figure 4 The electric actuator 73 is fixedly installed on the top wall inside the storage box 71, and the piston rod of the electric actuator 73 is vertically downward and fixedly connected to the upper surface of the moving piston 72. A control board for controlling the electric actuator 73 is also fixedly installed on the top wall inside the storage box 71. The water level detector 76 is fixedly installed on the inner side wall of the pool 1, and the water level detector 76 is used to detect the water level in the pool 1. At the same time, the water level detector 76 is electrically connected to the control board. Therefore, the water level detector 76 detects the water level in the pool 1, and the water level detector 76 controls the movement of the electric actuator 73 through the control board.

[0085] Reference Figure 4 The delivery pipe 74 and the recovery pipe 75 are fixedly installed on the two opposite outer walls of the storage box 71, and the connection between the delivery pipe 74 and the recovery pipe 75 and the storage box 71 is located on the side near the bottom of the storage box 71 and communicates with the storage space. At the same time, the delivery pipe 74 is connected to the inlet pipe 62 and the recovery pipe 75 is connected to the outlet pipe 63. A delivery check valve 77 is fixedly installed on the delivery pipe 74, and a recovery check valve 78 is fixedly installed on the recovery pipe 75. The delivery check valve 77 can only allow the gas in the storage space to move to the inlet pipe 62 through the delivery pipe 74, while the recovery check valve 78 can only allow the gas in the control chamber 64 to enter the storage space through the outlet pipe 63 and the recovery pipe 75.

[0086] Reference Figure 1 and Figure 4 The water level detector 76 detects the water level in the pool 1. The water level detector 76 controls the electric actuator 73 to start, which drives the moving piston 72 to move downward. The moving piston 72 pushes helium gas through the delivery pipe 74 and the inlet pipe 62 into the control chamber 64. When it is necessary to output helium gas from the control chamber 64, the electric actuator 73 starts, which drives the moving piston 72 to move upward. The helium gas in the control chamber 64 enters the storage space through the output pipe 63 and the recovery pipe 75 for storage. This is to realize the input or output of gas into the control chamber 64.

[0087] Reference Figure 1 and Figure 5 The drain pipe 13 is fixedly installed on the outer wall of the pool body 1 on the side away from the control pipe 51 and the inlet pipe 11. An installation bracket 16 is fixedly installed on the inner wall of the pool body 1 on the side of the sewage pipe 12 close to the drain pipe 13. The upper and lower ends of the installation bracket 16 abut against the inner bottom wall and the inner top wall of the pool body 1, respectively. An overflow hole 17 is opened on the top of the installation bracket 16, which passes through the two opposite side walls of the installation bracket 16. A sliding hole 161 is opened on the bottom wall of the overflow hole 17, which communicates with the bottom end of the installation bracket 16 and the side wall of the overflow hole 17.

[0088] Reference Figure 1 and Figure 5The control mechanism 5 also includes a gate 52 and a drive assembly 53. The gate 52 is vertically slidably mounted on the sliding hole 161 and abuts against the overflow hole 17. At the same time, an entry groove for the gate 52 to enter is provided on the bottom wall of the pool body 1 and inside the mounting bracket 16. An overflow space 521 for water supply is formed between the top of the gate 52, the side wall of the overflow hole 17 and the top wall of the pool body 1. A drainage space 522 is formed between the gate 52, the mounting bracket 16 and the inner side wall of the pool body 1 near the drain pipe 13. The drainage space 522 is connected to the drain pipe 13 and the overflow space 521 is located above the sewage pipe 12.

[0089] Reference Figure 1 and Figure 2 During the rainy season, the water volume in pool 1 increases sharply, causing the water level to rise. Some of the water enters the sewage treatment plant through the flow space 65 for treatment, while the rest enters the drainage space 522 through the overflow space 521. Finally, the water is discharged into the municipal water pipe network and enters the river through the drainage pipe 13, thereby improving the treatment efficiency of rainwater and sewage.

[0090] Reference Figure 1 and Figure 5 The drive assembly 53 is mounted on the mounting frame 16 and is used to drive the gate 52 to move. The drive assembly 53 is a drive cylinder, and the drive cylinder is fixedly mounted on the inner side wall of the mounting frame 16. At the same time, the piston rod of the drive cylinder is vertically upward and connected to the gate 52. The gate 52 is provided with an anti-backflow assembly 8, which includes a baffle plate 81 and an airbag 82. The baffle plate 81 is vertically slidably mounted on the side wall of the gate 52 near the drainage space 522, and the baffle plate 81 is used to block the overflow space 521. The airbag 82 is fixedly mounted on the lower surface of the baffle plate 81, and the airbag 82 is filled with an inert gas, which can be helium. At the same time, the airbag 82 floats on the water surface in the drainage space 522 to position the baffle plate 81.

[0091] Reference Figure 1 and Figure 5 When water enters the drainage space 522 through the overflow space 521, the water in the drainage space 522 is then discharged through the drain pipe 13. The airbag 82 floats on the water surface, while the baffle plate 81 is located below the overflow space 521. When the river water flows back into the drainage space 522 through the drain pipe 13, the water level in the drainage space 522 rises above the drain pipe 13. The rise in water level causes the baffle plate 81 to rise and block the overflow space 521, preventing the water in the drainage space 522 from flowing back into the pool 1 through the overflow space 521.

[0092] Reference Figure 1 and Figure 2The bottom wall of the pool 1 is provided with a receiving groove 18. The pool 1 is provided with a cleaning mechanism 9. The cleaning mechanism 9 includes a filter plate 91, a sewage pump 92, a cleaning pump 93, a cleaning pipe 94, a sealing ring 95, and a cleaning plate 96. The filter plate 91 is fixedly installed on the side wall of the receiving groove 18, while the sewage pump 92 is placed on the upper surface of the filter plate 91. The sewage pump 92 is fixedly installed with a sewage outlet pipe 921 extending above the impurity removal frame 21. The cleaning pump 93 is fixedly installed on the bottom wall of the receiving groove 18 and is located below the filter plate 91. A support plate 10 is fixedly installed on the inner side wall of the pool body 1, near the bottom wall of the pool body 1. A cleaning pipe 94 is fixedly installed on the support plate 10. The cleaning pipe 94 is vertical and its top is sealed. Multiple support plates 10 and cleaning pipes 94 are horizontally spaced. A water supply pipe 931 is fixedly installed on the cleaning pump 93 and is fixedly connected to the outer side wall of multiple cleaning pipes 94. The water supply pipe 931 is connected to the cleaning pipe 94.

[0093] Reference Figure 2 and Figure 6 A rotating column 932 is coaxially rotatably mounted on the inner top wall of the water supply pipe 931, and a sealing ring 95 is coaxially fixedly mounted on the bottom end of the rotating column 932, and the sealing ring 95 abuts against the bottom end of the cleaning pipe 94 to seal it; multiple cleaning plates 96 are arranged in a circumferential array around the axis of the rotating column 932, and the cleaning plate 96 includes a vertical part 97 and a horizontal part 98 connected together. The vertical part 97 is fixedly mounted on the edge of the lower surface of the sealing ring 95 and is arranged vertically downward, while the horizontal part 98 is located on the bottom end of the vertical part 97 and is arranged along the sealing ring 95. The radial direction extends away from the sealing ring 95; a rotating groove 99 is vertically and downwardly provided on the side wall of the vertical part 97 away from the axis of the rotating column 932, and the bottom end of the rotating groove 99 is inclined downward and connected to the side wall of the vertical part 97 adjacent to the rotating groove 99. At the same time, the bottom end of the rotating groove 99 extends to the connection between the vertical part 97 and the horizontal part 98, and the rotating groove 99 penetrates the top end of the vertical part 97. Meanwhile, a connecting hole 961 is provided on the sealing ring 95 at the position corresponding to the rotating groove 99, and the connecting hole 961 connects the inside of the cleaning tube 94 and the rotating groove 99.

[0094] Reference Figure 1 , Figure 2 and Figure 6When the sewage pump 92 starts, the water containing mixed impurities in the receiving tank 18 is transported to the impurity removal frame 21 through the sewage outlet pipe 921. After filtration, the water flows into the pool body 1, while the impurities remain in the impurity removal frame 21. At the same time, the cleaning pump 93 starts, and the water filtered by the filter plate 91 enters the cleaning pipe 94 through the water supply pipe 931. Then, the water is sprayed into the rotating tank 99 through the connecting hole 961. The water pushes the cleaning plate 96 to rotate, so the water forms a ring to clean the bottom wall of the pool body 1. At the same time, the rotation of the cleaning plate 96 agitates the water on the bottom wall of the pool body 1, causing the sedimented impurities to float to the surface and the water to move to the sewage pump 92 to remove impurities from the water.

[0095] The working principle of this application embodiment is as follows:

[0096] During the dry season, the inlet pipe 11 contains only sewage. The sewage flows along the side wall of the pool 1 into the receiving hood 41, and then flows through the receiving pipe 42 and the sewage discharge pipe 12 to the sewage treatment plant for treatment. During the rainy season, the sewage and rainwater in the inlet pipe 11 mix, increasing the water volume. As a result, the water flows into the liquid inlet pipe 22. Some of the water is filtered through the filter screen 23 and enters the liquid outlet chamber 222. The water impacts the rotating deflector 24 and flows into the pool 1. Other water and impurities enter the liquid inlet chamber 221. The rotating deflector 24 drives the cutting blade 25 to break up the impurities. The impurities then fall into the impurity removal frame 21 for collection, while the water flows through the impurity removal frame 21 into the pool 1. This process filters impurities in the water, thereby improving the treatment effect of rainwater and sewage.

[0097] The water level detector 76 detects the water level and controls the electric actuator 73 to move the moving piston 72, thereby adjusting the size of the space through which the water passes and thus the amount of water entering the sewage treatment plant. When the water level in the pool 1 rises above the control pipe 51, some water continues to move to the sewage treatment plant, while the rest flows through the overflow space 521 to the drainage space 522. Finally, the water is discharged into the municipal pipe network through the drainage pipe 13, thus achieving the effect of water diversion and improving the treatment effect of rainwater and sewage.

[0098] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
