Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a drainage device based on a separate sewer system for municipal roads. Background Art

[0002] Drainage devices generally refer to equipment and structures used to manage and control the flow of water, prevent waterlogging, and protect buildings, roads, and other infrastructure. These devices are crucial in urban planning and construction. Especially when facing heavy rain or other hydrological events, they can effectively drain water, maintaining environmental safety and sustainability. These drainage devices play an important role in urban planning and construction. They can not only improve the flood resistance ability and water resource utilization efficiency of cities, but also protect the environment and improve the quality of life of residents. With the intensification of urbanization and the impact of climate change, it is crucial to design and maintain a good drainage system to cope with changing hydrological challenges.

[0003] Drainage devices generally consist of a water collection device, a water delivery pipe, and a drainage pipe. When a large amount of water needs to be discharged, it is difficult for ordinary drainage devices to quickly discharge the water, and the water pressure of the discharged water is relatively high, which is likely to cause a certain impact on the external environment. At the same time, too high water pressure is also likely to squeeze the water delivery pipe, resulting in the rupture of the water delivery pipe. For water resources that can be directly discharged, secondary utilization can be carried out. Ordinary drainage devices directly discharging the water easily causes waste of water resources. When ordinary drainage devices are working, they are likely to collect and discharge sewage and directly dischargeable water together. If the sewage is directly discharged, it will cause a certain degree of environmental pollution. If it is discharged after purification, purifying the directly dischargeable water easily causes waste of resources. To solve the above problems, a drainage device based on a separate sewer system for municipal roads is proposed. Content of the Utility Model

[0004] To solve the above technical problems, a drainage device based on a separate sewer system for municipal roads is provided, which solves the problems that the current drainage devices generally consist of a water collection device, a water delivery pipe, and a drainage pipe. When a large amount of water needs to be discharged, it is difficult for ordinary drainage devices to quickly discharge the water, and the water pressure of the discharged water is relatively high, which is likely to cause a certain impact on the external environment. At the same time, too high water pressure is also likely to squeeze the water delivery pipe, resulting in the rupture of the water delivery pipe. For water resources that can be directly discharged, secondary utilization can be carried out. Ordinary drainage devices directly discharging the water easily causes waste of water resources. When ordinary drainage devices are working, they are likely to collect and discharge sewage and directly dischargeable water together. If the sewage is directly discharged, it will cause a certain degree of environmental pollution. If it is discharged after purification, purifying the directly dischargeable water easily causes waste of resources.

[0005] To achieve the above object, the technical solution adopted by the present utility model is as follows: A drainage device based on a separate sewer system for municipal roads, including a sewage purification tank. The upper left end of the sewage purification tank is fixedly connected to a main sewage pipe, and a first pressure gauge is fixedly installed on the main sewage pipe. The left side of the main sewage pipe is fixedly connected to a connecting elbow, and a sewage hopper is clamped on the upper side of the connecting elbow. A water pump is fixedly installed on the upper side of the sewage purification tank. The right side of the sewage purification tank is fixedly connected to a water storage tank. The central position on the upper side of the water storage tank is fixedly connected to a water inlet pipe, and a water inlet hopper is clamped on the upper side of the water inlet pipe. The lower right end of the water storage tank is fixedly connected to a first drain pipe, and a first electromagnetic valve is fixedly installed on the first drain pipe. The lower side of the water inlet pipe penetrates through the upper side of the water storage tank and is fixedly installed with a second electromagnetic valve. The upper right end of the water storage tank is fixedly connected to a second drain pipe, and a second pressure gauge is fixedly installed on the second drain pipe. The left end of the second drain pipe penetrates through the right side plate of the water storage tank and communicates with the lower end inside the water inlet pipe. A downcomer is fixedly connected to the lower side of the second electromagnetic valve.

[0006] Preferably, a first filter screen is clamped at the upper end inside the sewage hopper.

[0007] Preferably, the input end of the water pump is fixedly connected to a purified water delivery pipe, and the lower end of the purified water delivery pipe penetrates through the upper side of the sewage purification tank and communicates with the purified water area inside the sewage purification tank.

[0008] Preferably, a connecting pipe is fixedly connected to the upper left end of the water storage tank, and the left end of the connecting pipe is fixedly connected to the output end of the water pump.

[0009] Preferably, a second filter screen is clamped at the upper end inside the water inlet hopper.

[0010] Preferably, a fixing rod is fixedly connected to the front end of the lower side inside the water storage tank, and the upper side of the fixing rod is fixedly connected to the lower side of the top plate of the water storage tank.

[0011] Preferably, a water level sensor is slidably connected to the surface of the fixing rod.

[0012] Preferably, a ventilation hole is formed through the upper right end of the water storage tank.

[0013] Compared with the prior art, the advantages of the present utility model are as follows: By setting a water pump, a water storage tank, a water inlet pipe, a first drain pipe, a first electromagnetic valve, a second drain pipe, a second pressure gauge, a second electromagnetic valve, and a downspout, when a large amount of water needs to be discharged, the water can be discharged quickly. Opening the second electromagnetic valve to divert the water can effectively reduce the water pressure, avoid impacting the external environment, prevent the water pressure from being too high to squeeze the water delivery pipe, prevent the water delivery pipe from bursting, and can also collect the directly dischargeable water resources to avoid wasting water resources. By setting a sewage main pipe, a connecting elbow, a sewage hopper, and a sewage purification tank, the sewage and non-polluted water can be collected separately, avoiding pollution to the environment caused by the direct discharge of sewage and also avoiding waste of resources caused by the purification treatment of the directly dischargeable water.

[0018] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0019] Referring to Figure 1-2 as shown, a drainage device based on a separate sewerage network of municipal roads includes a sewage purification tank 1. The upper left end of the sewage purification tank 1 is fixedly connected with a sewage main pipe 2. A first pressure gauge 3 is fixedly installed on the sewage main pipe 2 to effectively detect the water pressure inside the sewage main pipe 2. The left side of the sewage main pipe 2 is fixedly connected with a connecting elbow 4. A sewage hopper 5 is clamped on the upper side of the connecting elbow 4. A first filter screen 6 is clamped at the upper end inside the sewage hopper 5 to effectively filter impurities and prevent the sewage hopper 5 from being blocked.

[0020] Specifically, a water pump 7 is fixedly installed on the upper side of the sewage purification tank 1. The input end of the water pump 7 is fixedly connected to a purified water delivery pipe 8. The lower end of the purified water delivery pipe 8 penetrates through the upper side of the sewage purification tank 1 and communicates with the purified water area inside the sewage purification tank 1. The right side of the sewage purification tank 1 is fixedly connected to a water storage tank 9. The left end of the upper side of the water storage tank 9 is fixedly connected to a connecting pipe 10. The left end of the connecting pipe 10 is fixedly connected to the output end of the water pump 7. The center position of the upper side of the water storage tank 9 is fixedly connected to a water inlet pipe 11. The upper side of the water inlet pipe 11 is clamped with a water inlet hopper 12. The upper end inside the water inlet hopper 12 is clamped with a second filter screen 13, which effectively filters impurities and prevents the water inlet hopper 12 from being blocked.

[0021] Specifically, the right lower end of the water storage tank 9 is fixedly connected to a first drain pipe 14. A first electromagnetic valve 15 is fixedly installed on the first drain pipe 14, which effectively controls the discharge of water inside the water storage tank 9. The front end of the lower side inside the water storage tank 9 is fixedly connected to a fixing rod 16. The upper side of the fixing rod 16 is fixedly connected to the lower side of the top plate of the water storage tank 9. A water level sensor 17 is slidably connected to the surface of the fixing rod 16, which can detect the water level height inside the water storage tank 9 in real time and prevent the stored water resources from being excessive. The lower side of the water inlet pipe 11 penetrates through the upper side of the water storage tank 9 and is fixedly installed with a second electromagnetic valve 18, which effectively controls the water flow direction inside the water inlet pipe 11. The right upper end of the water storage tank 9 is fixedly connected to a second drain pipe 19. A second pressure gauge 20 is fixedly installed on the second drain pipe 19, which effectively detects the water pressure inside the second drain pipe 19. The left end of the second drain pipe 19 penetrates through the right side plate of the water storage tank 9 and communicates with the lower end inside the water inlet pipe 11. The lower side of the second electromagnetic valve 18 is fixedly connected to a downcomer 21. A ventilation hole 22 is opened through the upper right end of the water storage tank 9, which effectively ensures that the pressure inside the water storage tank 9 is consistent with the external pressure.

[0022] Working principle: The connecting elbow 4 and the water inlet pipe 11 can be connected by connectors to clamp several sewage hoppers 5 and water inlet hoppers 12. The sewage hoppers 5 and water inlet hoppers 12 are installed in appropriate positions. The sewage to be discharged enters the sewage purification tank 1 through the sewage hopper 5, the connecting elbow 4 and the sewage main pipe 2. The first pressure gauge 3 detects the water pressure inside the sewage main pipe 2 in real time. The purified sewage is transported into the storage tank 9 under the action of the water pump 7 and can be directly discharged through the first drain pipe 14 or stored in the storage tank 9 for secondary use. If there is a large amount of sewage to be discharged and the water pressure inside the sewage main pipe 2 is high, the water pump 7 can also form a negative pressure in the purified water area of the sewage purification tank 1 through the purified water delivery pipe 8 to accelerate the collection of sewage. When the second electromagnetic valve 18 is closed, the water that can be directly discharged is discharged through the water inlet hopper 12, the water inlet pipe 11 and the second drain pipe 19. When the second electromagnetic valve 18 is opened, under the action of gravity, the water that can be directly discharged is collected inside the storage tank 9 through the downcomer 21 and used for secondary use. The second pressure gauge 20 detects the water pressure inside the second drain pipe 19 in real time. When the discharged water pressure is high, the second electromagnetic valve 18 is opened to divert the water inside the water inlet pipe 11 and reduce the water pressure inside the second drain pipe 19. When the first electromagnetic valve 15 is opened, the water inside the storage tank 9 can be directly discharged or used for secondary use.
