Description

Technical Field

[0001] The utility model belongs to the technical field of rainwater and sewage diversion pipes, and in particular relates to a municipal rainwater and sewage diversion pipe. Background Art

[0002] Municipal rainwater-sewage separation pipe is a pipe used to manage urban drainage systems. Its purpose is to separate rainwater and sewage in the pipe system for more efficient treatment. By collecting and treating rainwater and sewage separately, the burden on sewage treatment plants can be reduced, and the risk of overload of sewage treatment facilities caused by heavy rain weather can be reduced.

[0003] In traditional urban drainage systems, rainwater and sewage usually enter through the same pipe, which is usually called a mixed drainage system. Therefore, a rainwater and sewage diversion device is needed to distinguish and drain rainwater and sewage. Common rainwater and sewage diversion devices usually use infiltration technology to infiltrate clearer rainwater into the pipe below for discharge, while sewage is blocked by the interception net and discharged from above, thereby achieving separation. However, in actual use, when there are more impurities in the sewage, the impurities can easily block the interception net used for infiltration, thereby affecting the normal downward infiltration of rainwater, and then affecting the diversion of rainwater, which can easily cause the sewage treatment system to be overloaded. Utility Model Content

[0004] The utility model provides a municipal rainwater and sewage diversion pipe, which has the characteristic of solving the problem of sewage blockage affecting rainwater diversion.

[0005] The utility model provides the following technical solutions: including a diversion box, an inlet pipe, a sewage discharge pipe and a rainwater discharge pipe, the inner wall of the diversion box is fixedly connected with a blocking horizontal plate, the inner wall of the blocking horizontal plate is fixedly connected with an interception net, the inner wall of the interception net is rotatably connected with a rotating rod, the side wall of the rotating rod is fixedly connected with a plurality of water flow driving plates, the bottom ends of a plurality of the water flow driving plates are fixedly connected with an "L"-shaped scraper rod, one end of a plurality of the "L"-shaped scraper rods are fixedly connected to the side wall of the rotating rod, the "L"-shaped scraper rod is slidably connected to the top of the interception net, and a plurality of the water flow driving plates are alternately rotated to a position corresponding to the interface of the inlet pipe.

[0006] Among them, one side of several water flow driving plates is fixedly connected with a triangular arc plate, and the triangular arc plate is located on the side of the water flow driving plate close to the output water flow direction of the inlet pipe, and the triangular arc plate is not in contact with the diversion box and the blocking horizontal plate.

[0007] Among them, several of the "L"-shaped scraper rods are fixedly connected to an inclined plate on one side, and several of the inclined plates are rotatably connected to the top of the interception net.

[0008] Wherein, a through hole is opened at the top of the blocking horizontal plate, and the through hole corresponds to the position of the intercepting net.

[0009] Among them, a backup motor corresponding to the rotating rod is installed on the inner wall of the top end of the diverter box, the rotating rod is rotatably connected to the output end of the backup motor, and a ratchet gear is arranged between the backup motor and the rotating rod.

[0010] The beneficial effect of the utility model is that the water flow drives the water flow driving plate to rotate through the water flow, so that the water flow driving plate can drive the "L"-shaped scraper rod to scrape the sewage, garbage and impurities on the interception net, thereby reducing the obstruction and blockage of the interception net mesh by garbage and impurities in the sewage, ensuring the stability of the interception net for rainwater passing through, and reducing the occurrence of overload of the sewage treatment system.

[0011] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] See also Figure 1-Figure 4 The utility model provides the following technical solutions: it includes a diversion box 1, an inlet pipe 11, a sewage discharge pipe 12 and a rainwater discharge pipe 13, the inner wall of the diversion box 1 is fixedly connected with a blocking horizontal plate 14, the inner wall of the blocking horizontal plate 14 is fixedly connected with an interception net 2, the inner wall of the interception net 2 is rotatably connected with a rotating rod 3, and the side wall of the rotating rod 3 is fixedly connected with a plurality of water flow driving plates 31, the bottom ends of the plurality of water flow driving plates 31 are fixedly connected with "L"-shaped scraping rods 32, one end of the plurality of "L"-shaped scraping rods 32 are fixedly connected to the side wall of the rotating rod 3, the "L"-shaped scraping rods 32 are slidably connected to the top of the interception net 2, and the plurality of water flow driving plates 31 rotate alternately to the corresponding position with the interface of the inlet pipe 11.

[0018] In this embodiment: the diversion box 1 supports and protects the components of the device from the outside, the inlet pipe 11 collects rainwater and sewage into the diversion box 1, and the blocking horizontal plate 14 separates the internal space of the diversion box 1 into upper and lower parts. After the inlet pipe 11 guides the rainwater and sewage into the diversion box 1, the rainwater and sewage reach the top of the blocking horizontal plate 14, and the garbage impurities in the sewage are intercepted by the interception net 2. The clearer rainwater penetrates the interception net 2 and enters the space below the blocking horizontal plate 14. The sewage discharge pipe 12 and the rainwater discharge pipe 13 distinguish and discharge the diverted rainwater and sewage. When the inlet pipe 11 discharges rainwater and sewage, the discharge position of the inlet pipe 11 corresponds to the water flow driving plate 31, so that the flow of rainwater and sewage The impact force can impact the water flow driving plate 31, pushing the water flow driving plate 31 to rotate, and the water flow driving plate 31 drives the rotating rod 3 to rotate, and the rotating rod 3 drives the other several water flow driving plates 31 to rotate synchronously, so as to achieve the rotation cycle of the rotating rod 3 and the water flow driving plate 31, and the water flow driving plate 31 supports and drives the corresponding "L"-shaped scraper rod 32 to rotate. When rotating, the water flow driving plate 31 can drive the "L"-shaped scraper rod 32 to rotate synchronously, and the "L"-shaped scraper rod 32 scrapes the sewage, garbage and impurities on the interception net 2, thereby reducing the garbage and impurities in the sewage blocking and clogging the mesh of the interception net 2, ensuring the stability of the interception net 2 for rainwater passing through, and reducing the occurrence of overload of the sewage treatment system.

[0019] A triangular arc plate 33 is fixedly connected to one side of several water flow driving plates 31. The triangular arc plate 33 is located on the side of the water flow driving plate 31 close to the output water flow direction of the inlet pipe 11, and the triangular arc plate 33 is not in contact with the diversion box 1 and the blocking cross plate 14; when the water flow driving plate 31 rotates to the output water source position angle of the inlet pipe 11, the water flow driving plate 31 drives the corresponding triangular arc plate 33 to contact the sewage and rainwater inlet section, and the rainwater and sewage impact the water flow driving plate 31 and the triangular arc plate 33. When the triangular arc plate 33 rotates with the water flow driving plate 31, the triangular arc plate 33 can use its own triangular shape to increase the impact effect of the water flow on the water flow driving plate 31, so that the rotation operation of the water flow driving plate 31 can be kept more stable.

[0020] One side of a plurality of "L"-shaped scraper rods 32 is fixedly connected with an inclined plate 321, and a plurality of inclined plates 321 are rotatably connected to the top of the interception net 2; the "L"-shaped scraper rods 32 support and rotate the inclined plates 321, and when the water flow driving plate 31 drives the "L"-shaped scraper rods 32 to rotate, the "L"-shaped scraper rods 32 drive the inclined plates 321 to rotate, and the inclined plates 321 use their narrower ends to scoop and clean garbage and impurities on the top surface of the interception net 2, thereby improving the effect of the "L"-shaped scraper rods 32 in removing garbage and impurities, thereby keeping the water seepage effect of the interception net 2 stable.

[0021] A through hole 141 is provided at the top of the blocking horizontal plate 14, and the through hole 141 corresponds to the position of the interception net 2; the through hole 141 uses its inclined surface to drain sewage and rainwater to the interception net 2 for gathering, thereby facilitating rainwater to pass through the interception net 2 and reach the bottom for discharge.

[0022] A backup motor 34 corresponding to the rotating rod 3 is installed on the inner wall of the top end of the diversion box 1, and the rotating rod 3 is rotatably connected to the output end of the backup motor 34, and a ratchet gear is arranged between the backup motor 34 and the rotating rod 3; the backup motor 34 is located on the inner side of the top end of the diversion box 1, and the backup motor 34 is a backup setting. Under the action of the ratchet gear between the backup motor 34 and the rotating rod 3, when the rotating rod 3 rotates driven by the water flow driving plate 31, it will not be limited by the backup motor 34. When the water flow rate is insufficient, it is difficult for the water flow driving plate 31 to drive the rotating rod 3 to rotate stably. By controlling the backup motor 34 to drive the rotating rod 3 to rotate, the backup motor 34 can normally drive the rotating rod 3 to rotate under the action of the ratchet gear, so that the rotating rod 3 can drive a number of "L"-shaped scraping rods 32 through the water flow driving plate 31 to scrape and separate the garbage and impurities on the interception net 2, thereby ensuring the stability of rainwater diversion.

[0023] The working principle and use process of the utility model are as follows: when the device is used, rainwater and sewage are discharged into the internal space of the diversion box 1 through the merging pipe 11, and the rainwater and sewage discharged use their own water flow impact force to impact the water flow driving plate 31 and the triangular arc plate 33, and the triangular arc plate 33 and the water flow driving plate 31 passively drive the rotating rod 3 to rotate, and the rotating rod 3 drives the other several water flow driving plates 31 to rotate synchronously, so as to achieve the rotation cycle of the rotating rod 3 and the water flow driving plate 31, and the water flow driving plate 31 supports and rotates the corresponding "L"-shaped scraper rod 32, and the water flow driving plate 31 can drive the "L"-shaped scraper rod 32 to rotate synchronously when rotating, and the "L"-shaped scraper rod 32 scrapes the sewage, garbage and impurities on the interception net 2, thereby reducing the garbage and impurities in the sewage blocking and clogging the mesh of the interception net 2, ensuring the stability of the interception net 2 for rainwater passing, and reducing the occurrence of overload of the sewage treatment system.
