Description

Technical Field

[0001] This utility model relates to the field of drainage equipment technology, specifically to a portable active siphon system for rapid drainage, which is suitable for water conservancy, emergency response and other departments for flood control and drainage or strong drainage operations in reservoirs. Background Technology

[0002] Currently, water conservancy and emergency management departments require a large number and variety of mobile pumps for flood control, drainage, and intensive drainage operations at reservoirs to adapt to different geographical environments, transportation, and manpower conditions. Among these, small ponds and reservoirs commonly found in the mountainous regions of southern China, such as Sichuan, Chongqing, Zhejiang, and Fujian, as well as landslide-dammed lakes caused by geological disasters like earthquakes and landslides, present unique and challenging environments for construction, including large scale, remoteness, dispersion, lack of electricity, and absence of standard road surfaces. This makes traditional standby electric submersible pumps, gasoline and diesel pumps, small handheld pumps, and large truck-mounted pumps unusable.

[0003] As is well known, the siphon principle can be used to transfer and discharge water, and therefore it is also used in reservoir flood control and drainage operations. The basic process involves placing a siphon pipe above the dam with one end inserted into the water. Simultaneously, a separate steam (or diesel) water pump and inlet / outlet pipes are used to draw water, which is then poured into the siphon pipe. As the water enters, the gas is expelled, creating a siphon effect. However, the following problems exist: 1. Fixed siphon drainage equipment, although with large flow rates and stable operation, requires supporting infrastructure such as concrete foundations, resulting in high operating costs and long construction periods. 2. Mobile siphon drainage equipment, while flexible, requires significant manpower in actual operation. It also requires a separate pump system as a start-up source, necessitating repeated water intake, extraction, and injection, leading to long operation times, low efficiency, and safety hazards such as workers falling into the water. The level of automation still needs improvement. Utility Model Content

[0004] The purpose of this invention is to provide a portable active siphon system for rapid drainage that is simple in structure and reliable in use, which solves the above-mentioned problems. Compared with fixed siphon drainage equipment, it is convenient and flexible to use and has low operating costs. At the same time, compared with mobile siphon drainage equipment, it further improves the level of automation, reduces the labor intensity of workers, improves drainage efficiency, and reduces safety hazards.

[0005] The technical solution of this utility model is:

[0006] A portable active siphon system for rapid drainage includes a vacuum pump body. The key technical features are: one side of the impeller cavity of the vacuum pump body is connected to an air extraction pipe, and the other side is connected to an exhaust pipe. The other end of the air extraction pipe is connected to a negative pressure control pipe, and the other end of the exhaust pipe is connected to the atmosphere. The two ends of the negative pressure control pipe are used to connect to the water inlet section and the drainage section of the siphon pipe, respectively. A pressure relief pipe connected to the atmosphere is also provided on the top surface of the negative pressure control pipe. A first control valve is provided on the air extraction pipe, a second control valve is provided on the exhaust pipe, and a third control valve is provided on the pressure relief pipe.

[0007] The portable active siphon system for rapid drainage described above is powered by a 380V DC battery.

[0008] The aforementioned portable active siphon system for rapid drainage has an air inlet chamber and an air outlet chamber that are connected to the impeller cavity inside the end plate of the vacuum pump body. The suction pipe and the exhaust pipe are respectively fixed to the top of the end plate, and the suction pipe is connected to the air inlet chamber and the exhaust pipe is connected to the exhaust chamber.

[0009] The aforementioned portable active siphon system for rapid drainage has a water injection hole on the end plate of the vacuum pump body that communicates with the cavity where the impeller is located. The outer end of the water injection hole is connected to a water injection pipe, and the other end of the water injection pipe is connected to the outlet of the water injection bottle. The outlet height of the water injection bottle is higher than the height of the water injection hole.

[0010] The aforementioned portable active siphon system for rapid drainage has a U-shaped air extraction pipe with the bottom section of the U higher than the top surface of the negative pressure control pipe. The top surface of the negative pressure control pipe is provided with a connection port that communicates with the end of the air extraction pipe, and the first control valve is located at the bottom section of the U-shaped air extraction pipe.

[0011] The aforementioned portable active siphon system for rapid drainage has a housing surrounding the middle outer side of the vacuum pump body and the negative pressure control pipe. The first control valve and its pipe section, the second control valve and the end of the exhaust pipe, and the third control valve and the end of the pressure relief pipe all protrude from the top surface of the housing. The two ends of the negative pressure control pipe are respectively led out from the front and rear end faces of the housing.

[0012] The aforementioned portable active siphon system for rapid drainage has a gate valve at the end of the drainage section of the siphon pipe.

[0013] The portable active siphon system for rapid drainage described above uses a permanent magnet brushless motor as the motor in the vacuum pump body.

[0014] The beneficial effects of this utility model are:

[0015] 1. Utilizing biomimetic vacuum pumping technology, this integrated design maximizes portability, ease of use, and flexibility, resulting in lower operating costs compared to fixed drainage systems. A vacuum pump automatically draws air, creating a negative pressure vacuum environment in the negative pressure control pipe connected to the siphon inlet and outlet sections. This allows water to automatically flow into these sections, achieving automatic water supply and rapid drainage, significantly improving the efficiency of forced drainage operations. The elimination of the need for a water pump and associated piping reduces the workload for operators; only 1-2 people are required to operate the device, minimizing safety hazards during water collection.

[0016] 2. During the operation of the vacuum pump body, a cooling water flow is slowly injected into the cavity where the impeller of the vacuum pump body is located to dissipate the high heat generated during the pumping operation, thus ensuring the stability and reliability of the vacuum pump body's pumping operation.

[0017] 3. The pumping and drainage can be stopped in a timely manner as needed, making the operation flexible.

[0018] 4. This utility model has strong application and promotion value and economic value for flood control, drainage or intensive drainage operations. Attached Figure Description

[0025] The present invention will be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-5As shown, the portable active siphon system for rapid drainage includes a vacuum pump body 7.

[0027] In this embodiment, the vacuum pump body 7 has an impeller 702 located in a cavity connected to an air extraction pipe 2 on one side and an exhaust pipe 4 on the other side. The other end of the air extraction pipe 2 is connected to a negative pressure control pipe 6, and the other end of the exhaust pipe 4 is connected to the atmosphere. The negative pressure control pipe 6 is connected at both ends to a siphon pipe inlet section 14 and a siphon pipe outlet section 12, respectively. A pressure relief pipe 8 connected to the atmosphere is also provided on the top surface of the negative pressure control pipe 6. In this embodiment, the power source for the vacuum pump body 7 is a portable energy storage power source, specifically a 380V DC battery, and the motor used in the vacuum pump body 7 is a permanent magnet brushless motor.

[0028] The end plate 701 of the vacuum pump body 7 has an air inlet chamber and an exhaust chamber that communicate with the cavity where the impeller 702 is located. The suction pipe 2 and the exhaust pipe 4 are respectively fixed to the top of the end plate 701, with the suction pipe 2 communicating with the air inlet chamber and the exhaust pipe 4 communicating with the exhaust chamber. The end plate 701 of the vacuum pump body 7 has a water injection hole 703 that communicates with the cavity where the impeller 702 is located. The outer end of the water injection hole 703 is connected to a water injection pipe 11, and the other end of the water injection pipe 11 is connected to the outlet of the water injection bottle 10. In use, the outlet height of the water injection bottle 10 is higher than the height of the water injection hole 703.

[0029] The suction pipe 2 is equipped with a first control valve 3, the exhaust pipe 4 is equipped with a second control valve 5, and the pressure relief pipe 8 is equipped with a third control valve 9. In this embodiment, the suction pipe 2 is a U-shaped pipe with the bottom section of the U higher than the top surface of the negative pressure control pipe 6. The top surface of the negative pressure control pipe 6 is provided with a connection port communicating with the end of the suction pipe 2. The first control valve 3 is located at the bottom section of the U-shaped suction pipe 2. The vacuum pump body 7 and the negative pressure control pipe 6 are surrounded by a housing 1 on the outer side of their middle parts. The first control valve 3 and its pipe section, the second control valve 5 and the end of the exhaust pipe 4, and the third control valve 9 and the end of the pressure relief pipe 8 all protrude from the top surface of the housing 1 for easy operation. The two ends of the negative pressure control pipe 6 lead out from the front and rear ends of the housing 1, respectively.

[0030] In this embodiment, the device (excluding the siphon pipe inlet section 14 and the siphon pipe outlet section 12) weighs about 25 kg and has a volume of about 0.5 cubic meters, making it easy to transport.

[0031] The procedure for draining water is as follows:

[0032] In use, place the device on the top surface of the dam. Connect the two ends of the negative pressure control pipe 6 to the siphon pipe inlet section 14 and the siphon pipe outlet section 12 using quick connectors 13. Insert the inlet of the siphon pipe inlet section 14 into the water inside the dam. Arrange the siphon pipe outlet section 12 on the outside of the dam and extend it towards the discharge area. Simultaneously, install a gate valve 15 at the outlet of the siphon pipe outlet section 12. After the arrangement is completed, the height difference between the inlet of the siphon pipe inlet section 14 and the outlet of the siphon pipe outlet section 12 should be more than 1 meter.

[0033] Open the first control valve 3 and the second control valve 5, and close the third control valve 9. Connect the 380V DC battery power supply and start the vacuum pump body 7. The permanent magnet brushless motor of the vacuum pump body 7 drives the impeller to rotate and do work. The gas in the siphon pipe inlet section 14 and the siphon pipe outlet section 12 is drawn out through the suction pipe 2 and the negative pressure control pipe 6, and then discharged through the exhaust pipe 2. This creates a negative pressure vacuum state in the siphon pipe inlet section 14 and the siphon pipe outlet section 12. Under the action of negative pressure, the water inside the dam body is drawn into the siphon pipe inlet section 14 and goes to the siphon pipe outlet section 12. When the water flows out of the exhaust pipe 4, it means that the water has reached the gate valve 15 position and the water fills the siphon pipe inlet section 14, the negative pressure control pipe 6 and the siphon pipe outlet section 12. At this time, the first control valve 3, the second control valve 5, and the vacuum pump body 7 are shut down, and the gate valve 15 is opened. Under the dual action of negative pressure siphon effect and drop potential energy, the water continuously enters the siphon pipe inlet section 14 and is discharged to the drainage area from the siphon pipe drainage section 12, thereby achieving automatic drainage effect.

[0034] Before evacuation, cooling water can be supplied to the water inlet 703 through the water bottle 10 and water pipe 11. During operation, the water enters the cavity where the impeller 702 of the vacuum pump body 7 is located and is immersed on the surface of the impeller 702 to achieve the cooling effect.

[0035] When it is necessary to stop the drainage operation, open the third control valve 9, and the gas enters the negative pressure control pipe 6 through the pressure relief pipe 8, which breaks the siphon state and stops the automatic drainage operation.

[0036] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
