Description

Technical Field

[0001] The present invention relates to the technical field of drainage equipment, and particularly to a portable active siphon system for rapid drainage and its operation method, which is applicable to departments such as water conservancy and emergency for flood control and drainage or strong drainage operations of reservoirs. Background Art

[0002] Currently, in flood control and drainage, and strong drainage operations of reservoirs by departments such as water conservancy and emergency, a large number of and various types of motor pumps need to be used in combination to adapt to different geographical environments, transportation and manpower conditions. Among them, "small mountain ponds and small reservoirs" commonly found in mountainous areas in the south such as Sichuan, Chongqing, Zhejiang, and Fujian, as well as "water storage structures" such as barrier lakes caused by geological disasters such as earthquakes and landslides, have harsh environments that are particularly unfavorable for construction operations, such as large quantity, remoteness, dispersion, lack of electricity, and lack of standard roads, making it impossible to use traditional standing electric submersible pumps, gasoline / diesel pumps, small hand-held pumps, large vehicle-mounted pumps, etc.

[0003] As is well known, the siphon principle can be used to achieve the transfer and discharge of water bodies, and thus it has also been used in flood control and drainage, and strong drainage operations of reservoirs. Basically: The siphon pipeline is placed above the dam body and one end is inserted into the water body. At the same time, a set of gasoline (diesel) pump and inlet and outlet pipes are additionally configured to pump water, and then the water is poured into the siphon pipeline. As the water enters, the gas is discharged, generating a siphon effect. However, there are the following problems: 1. Fixed siphon drainage equipment, although having a large flow rate and stable working state, requires supporting projects such as pouring concrete bases, with high usage costs and long construction periods. 2. Mobile siphon drainage equipment, although flexible and mobile, requires a large amount of manpower in actual operations. Another water pump system is configured as a starting source, and it is necessary to repeatedly contact water, draw water, and inject water, with long operation time, low efficiency, and potential safety hazards of staff falling into the water, and the automation level still needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide a portable active siphon system for rapid drainage with a simple structure and reliable use and its operation method to solve the above problems. Compared with fixed siphon drainage equipment, it is convenient and flexible to use and has low usage costs. At the same time, compared with mobile siphon drainage equipment, it further improves the automation level, reduces the labor intensity of staff, improves the drainage efficiency, and reduces potential safety hazards.

[0005] The technical solution of the present invention is: A portable active siphon system for rapid drainage, including a vacuum pump body. The technical key points are as follows: One side of the cavity where the impeller of the vacuum pump body is located is connected with an air extraction pipeline, and the other side is connected with an exhaust pipeline. The other end of the air extraction pipeline is communicated with a negative pressure centralized control pipe, and the other end of the exhaust pipeline is communicated with the atmosphere. Both ends of the negative pressure centralized control pipe are used to connect the water inlet section and the drainage section of the siphon pipeline respectively. The top surface of the negative pressure centralized control pipe is further provided with a pressure relief pipeline communicated with the atmosphere. A first control valve is arranged on the air extraction pipeline, a second control valve is arranged on the exhaust pipeline, and a third control valve is arranged on the pressure relief pipeline.

[0006] For the above-mentioned portable active siphon system for rapid drainage, the power supply of the vacuum pump body is a 380V DC battery.

[0007] For the above-mentioned portable active siphon system for rapid drainage, an air inlet cavity and an exhaust cavity communicated with the cavity where the impeller is located are arranged inside the end plate of the vacuum pump body. The air extraction pipeline and the exhaust pipeline are respectively fixed on the top of the end plate, and the air extraction pipeline is communicated with the air inlet cavity, and the exhaust pipeline is communicated with the exhaust cavity.

[0008] For the above-mentioned portable active siphon system for rapid drainage, a water injection hole communicated with the cavity where the impeller is located is arranged on the end plate of the vacuum pump body. The outer end of the water injection hole is connected with a water injection pipe, and the other end of the water injection pipe is connected with the outlet of a water injection bottle. The height of the outlet of the water injection bottle is higher than the height where the water injection hole is located.

[0009] For the above-mentioned portable active siphon system for rapid drainage, the air extraction pipeline is a U-shaped pipeline and the U-bottom section is higher than the top surface of the negative pressure centralized control pipe. A connection port communicated with the end of the air extraction pipeline is arranged on the top surface of the negative pressure centralized control pipe. The first control valve is located at the U-bottom section of the air extraction pipeline.

[0010] For the above-mentioned portable active siphon system for rapid drainage, an outer shell is wrapped around the outer sides of the middle parts of the vacuum pump body and the negative pressure centralized control pipe. The first control valve and its corresponding pipe section, the second control valve and the end of the exhaust pipeline, and the third control valve and the end of the pressure relief pipeline all protrude from the top surface of the outer shell. Both ends of the negative pressure centralized control pipe respectively extend out of the front and rear end faces of the outer shell.

[0011] For the above-mentioned portable active siphon system for rapid drainage, a sluice valve is arranged at the end of the drainage section of the siphon pipeline.

[0012] For the above-mentioned portable active siphon system for rapid drainage, the motor adopted by the vacuum pump body is a permanent magnet brushless motor.

[0013] An operation method for the above-mentioned portable active siphon system for rapid drainage includes the following steps: Step 1: During use, arrange the vacuum pump body, negative pressure centralized control pipe and peripheral components on the top surface of the dam. Connect the two ends of the negative pressure centralized control pipe to the water inlet section and the drainage section of the siphon pipeline respectively using quick connectors. Insert the inlet of the water inlet section of the siphon pipeline into the water body inside the dam, arrange the drainage section of the siphon pipeline outside the dam and extend it towards the water discharge area. At the same time, install a gate valve at the outlet of the drainage section of the siphon pipeline. After the arrangement is completed, the height difference between the inlet of the water inlet section of the siphon pipeline and the outlet of the drainage section of the siphon pipeline should be more than 1 meter. Step 2: Open the first control valve and the second control valve, and close the third control valve. Start the vacuum pump body. The permanent magnet brushless motor of the vacuum pump body drives the impeller to rotate and do work. The gas in the water inlet section and the drainage section of the siphon pipeline is sucked out through the air extraction pipeline and the negative pressure centralized control pipe, and then discharged through the exhaust pipeline, thereby forming a negative pressure vacuum state in the water inlet section and the drainage section of the siphon pipeline. Under the action of negative pressure, the water body inside the dam is sucked into the water inlet section of the siphon pipeline and goes to the drainage section of the siphon pipeline. When water flows out of the exhaust pipeline, it indicates that the water body has reached the position of the gate valve, and the water body fills the water inlet section of the siphon pipeline, the negative pressure centralized control pipe and the drainage section of the siphon pipeline. Step 3: Close the first control valve and the second control valve, and stop the vacuum pump body. Open the gate valve, and the water body drains. At the same time, under the dual action of the negative pressure siphon effect and the drop potential energy, the water body inside the dam continuously enters the water inlet section of the siphon pipeline and is discharged from the drainage section of the siphon pipeline to the water discharge area, realizing the automatic drainage effect. Step 4: When it is necessary to stop the drainage operation, open the third control valve, and the gas enters the negative pressure centralized control pipe through the pressure relief pipeline, destroying the siphon state and stopping the automatic drainage operation.

[0014] In the above operation method, before the vacuum pump body performs the air extraction operation, place the water injection bottle at a position higher than the vacuum pump body, and connect it to the water injection hole through the water injection pipe. Deliver the cooling water flow to the water injection hole through the water injection pipe. During the operation of the vacuum pump body, the cooling water flow enters the cavity where the impeller of the vacuum pump body is located and soaks the surface of the impeller to achieve the cooling effect.

[0015] The beneficial effects of the present invention are: 1. Utilize bionic air extraction and drinking water to achieve an integrated design, maximizing the realization of light, simple and flexible operation. Compared with fixed drainage equipment, the use cost is low. The vacuum pump body automatically extracts air to form a negative pressure vacuum environment in the negative pressure centralized control pipe connected to the water inlet section and the drainage section of the siphon pipeline, enabling the water body to automatically fill the water inlet section of the siphon pipeline, the negative pressure centralized control pipe and the drainage section of the siphon pipeline, realizing the functions of automatic water filling and rapid drainage, and significantly improving the efficiency of strong drainage operations. There is no need to use a water pump and supporting pipelines to fill water into the siphon pipeline, reducing the labor intensity of the staff. One or two people can carry this device for operation, and it also reduces the safety hazards during the water intake process.

[0016] 2. During the operation of the vacuum pump body, cooling water flow is slowly injected into the cavity where the impeller of the vacuum pump body is located, so as to achieve the purpose of dissipating the high heat generated by the air extraction operation, ensuring the stability and reliability of the air extraction operation of the vacuum pump body.

[0017] 3. The pumping and drainage can be stopped in time according to needs, and the operation is flexible.

[0018] 4. The present invention has strong application promotion value and economic value for flood control and drainage or strong drainage operations. Description of the Drawings

[0021] The present invention will be described in detail according to the drawings in the specification.

[0022] As Figures 1 to 5 shown, the portable active siphon system for rapid drainage includes a vacuum pump body 7.

[0023] Among them, one side of the cavity where the impeller 702 of the vacuum pump body 7 is located is connected with an air extraction pipeline 2, and the other side is connected with an exhaust pipeline 4. The other end of the air extraction pipeline 2 is communicated with a negative pressure centralized control pipe 6, and the other end of the exhaust pipeline 4 is communicated with the atmosphere. Both ends of the negative pressure centralized control pipe 6 are used to connect the water inlet section 14 and the drainage section 12 of the siphon pipeline respectively. The top surface of the negative pressure centralized control pipe 6 is further provided with a pressure relief pipeline 8 communicated with the atmosphere. In this embodiment, the power supply of the vacuum pump body 7 is a mobile energy storage power supply, specifically a 380V DC battery, and the motor used in the vacuum pump body 7 is a permanent magnet brushless motor.

[0024] An air inlet chamber and an air outlet chamber communicating with the chamber where the impeller 702 is located are provided inside the end plate 701 of the vacuum pump body 7. The suction pipeline 2 and the exhaust pipeline 4 are respectively fixed to the top of the end plate 701, and the suction pipeline 2 communicates with the air inlet chamber, and the exhaust pipeline 4 communicates with the air outlet chamber. A water injection hole 703 communicating with the chamber where the impeller 702 is located is provided on the end plate 701 of the vacuum pump body 7. 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. During use, the height of the outlet of the water injection bottle 10 is higher than the height where the water injection hole 703 is located.

[0025] A first control valve 3 is provided on the suction pipeline 2, a second control valve 5 is provided on the exhaust pipeline 4, and a third control valve 9 is provided on the pressure relief pipeline 8. In this embodiment, the suction pipeline 2 is a U-shaped pipeline and the U-bottom section is higher than the top surface of the negative pressure centralized control pipe 6. A connection port communicating with the end of the suction pipeline 2 is provided on the top surface of the negative pressure centralized control pipe 6. The first control valve 3 is located at the U-bottom section of the suction pipeline 2. The outer sides of the middle parts of the vacuum pump body 7 and the negative pressure centralized control pipe 6 are surrounded by a housing 1. The first control valve 3 and its pipe section, the second control valve 5 and the end of the exhaust pipeline 4, and the third control valve 9 and the end of the pressure relief pipeline 8 all protrude above the top surface of the housing 1 for convenient operation. The two ends of the negative pressure centralized control pipe 6 respectively extend out of the front and rear end faces of the housing 1.

[0026] In this embodiment, the mass of the device (excluding the water inlet section 14 of the siphon pipeline and the water drainage section 12 of the siphon pipeline) is about 25 kg, and the volume is about 0.5 cubic meters, which is convenient for handling.

[0027] When draining water, the operation method is as follows: During use, place the device on the top surface of the dam body. The two ends of the negative pressure centralized control pipe 6 are respectively connected to the water inlet section 14 of the siphon pipeline and the water drainage section 12 of the siphon pipeline by using quick connectors 13. Insert the inlet of the water inlet section 14 of the siphon pipeline into the water body inside the dam body, arrange the water drainage section 12 of the siphon pipeline outside the dam body and extend it towards the water discharge area, and at the same time, a gate valve 15 is arranged at the outlet of the water drainage section 12 of the siphon pipeline. After the arrangement is completed, the height difference between the inlet of the water inlet section 14 of the siphon pipeline and the outlet of the water drainage section 12 of the siphon pipeline should be more than 1 meter.

[0028] 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 water inlet section 14 and the drainage section 12 of the siphon pipeline is sucked out through the suction pipeline 2 and the negative pressure centralized control pipe 6, and then discharged through the exhaust pipeline 2, so as to form a negative pressure vacuum state in the water inlet section 14 and the drainage section 12 of the siphon pipeline. Under the action of negative pressure, the water body inside the dam is sucked into the water inlet section 14 of the siphon pipeline and goes to the drainage section 12 of the siphon pipeline. When water flows out from the exhaust pipeline 4, it indicates that the water body has reached the position of the gate valve 15, and the water body fills the water inlet section 14, the negative pressure centralized control pipe 6 and the drainage section 12 of the siphon pipeline. At this time, close the first control valve 3, the second control valve 5, stop the vacuum pump body 7, and open the gate valve 15. Under the dual action of the negative pressure siphon effect and the head potential energy, the water body continuously enters the water inlet section 14 of the siphon pipeline and is discharged from the drainage section 12 of the siphon pipeline to the water discharge area, thus realizing the automatic drainage effect.

[0029] Before air extraction, cooling water flow can be conveyed to the water injection hole 703 through the water injection bottle 10 and the water injection pipe 11. During operation, after the water body enters the cavity where the impeller 702 of the vacuum pump body 7 is located, it soaks the surface of the impeller 702 to achieve the cooling effect.

[0030] When it is necessary to stop the drainage operation, open the third control valve 9. The gas enters the negative pressure centralized control pipe 6 through the pressure relief pipeline 8, destroys the siphon state, and stops the automatic drainage operation.

[0031] The above has described the embodiments of the present invention in detail, but the described content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made within the scope of the present invention shall still fall within the scope covered by this patent.
