Description

Technical Field

[0001] This utility model relates to the field of pumping device technology, and in particular to a self-priming valve well pumping device based on the siphon principle. Background Technology

[0002] In scenarios such as municipal drainage, underground utility tunnel maintenance, and disaster relief, underground facilities such as valve wells and underground utility tunnels are prone to water accumulation due to heavy rain, pipe ruptures, or groundwater leakage. If the accumulated water cannot be drained in time, it will not only cause damage to electrical equipment such as water immersion short circuits and corrosion, but also breed bacteria and mosquitoes, and even form methane (CH4) accumulation, posing an explosion risk. At the same time, manual water scooping is extremely inefficient, and working in confined spaces can easily lead to accidents such as suffocation and falls. However, the application of self-priming valve well pumping devices based on the siphon principle can achieve automatic water pumping without electricity by utilizing the difference in gravitational potential energy of liquids and atmospheric pressure. This effectively solves the emergency drainage problem in environments without power supply, ensures the safe and stable operation of underground facilities, improves the convenience and efficiency of drainage operations, and reduces operation and maintenance costs and safety risks.

[0003] In existing technologies, the treatment of water accumulation in underground facilities often employs equipment such as electric submersible pumps. These pumps rely on electricity to drive the impeller to rotate, generating centrifugal force to extract the water. Some also use manual siphon pipes, which remove air by manually sucking it out, thus achieving drainage through the siphon effect.

[0004] However, existing technologies have significant shortcomings in valve well pumping. Electric submersible pumps rely on electricity and cannot be used in environments without power, such as in the field or after a disaster. Equipping them with generators would increase costs and noise, and the transportation and wiring of the equipment would be time-consuming and difficult to cope with sudden flooding. Manual siphon pipes require manual suction to start, which poses hygiene risks, as operators may come into contact with sewage containing pathogens or chemical contaminants. At the same time, they cannot handle impurities in the sewage, which can easily lead to pipe blockage. This utility model provides a power-free, ready-to-use siphon drainage solution through a combined design of sealed water injection and rapid venting. It is especially suitable for emergency drainage in environments without electricity, such as municipal manholes and industrial pits. Utility Model Content

[0032] Reference Figures 1-3 This utility model provides an embodiment of a self-priming valve well pumping device based on the siphon principle, comprising a water storage tank 6. The water storage tank 6 is made of cavitation-resistant material and also has excellent impact resistance and chemical stability, enabling it to adapt to the complex water quality environment inside the valve well and ensuring long-term stable use of the device. It can adapt to the complex and diverse water quality environment inside the valve well, whether it is water containing weak acids or alkalis, or other liquids containing corrosive substances, ensuring long-term stable use of the device and preventing corrosion damage. A water inlet pipe 1 is fixedly connected to one side of the outer wall of the water storage tank 6. The water inlet pipe 1 is made of UPVC material. With good corrosion resistance and lightweight, the water storage tank 6 is fixedly connected to the bottom of the support bracket 3, providing stable support for the water storage tank 6 and keeping it horizontal and stable during water pumping operations, ensuring the smooth operation of the siphon process. The bottom end of the inlet pipe 1 is threadedly connected to the connector 2, and the bottom end of the connector 2 is threadedly connected to the connecting pipe 11. The connector 2 can tightly connect the inlet pipe 1 and the connecting pipe 11 to prevent water leakage from affecting the siphon effect. An observation window 7 is opened inside the water storage tank 6, and a scale line 16 is fixedly connected inside the water storage tank 6. Through the observation window 7 and the internal scale line 16, the operator can clearly see the water level in the water storage tank 6. The water tank 6 is positioned at a height that facilitates monitoring of water filling and pumping. A vent valve 10 is fixedly connected to the bottom of the water tank 6. When it is necessary to empty the water tank 6, opening the vent valve 10 allows for rapid drainage, facilitating maintenance and repair. A tank cover 17 is installed on the top of the water tank 6. A sealed water inlet 4 is fixedly connected to the top of the tank cover 17. The sealed water inlet 4 has a one-way valve. During water filling, the one-way valve prevents backflow; when closed, it ensures the airtightness of the water tank 6, providing the necessary conditions for siphon formation. A manual vent valve 5 is fixedly connected to the top of the tank cover 17. The manual vent valve 5 is made of brass and is easy to operate. In case of abnormality, the siphon can be interrupted by operating the manual air exchange valve 5 to ensure the safe use of the device. A corrugated pipe 9 is fixedly connected to the other side of the outer wall of the water storage tank 6. The corrugated pipe 9 is made of rubber and has good flexibility and aging resistance. It can adapt to different drainage point positions and facilitate the guidance of water to the lower drainage point. A drain valve 8 is set at one end of the corrugated pipe 9. The drain valve 8 is made of stainless steel and has a lever structure. It can be fully opened or closed by one hand. The siphon can be established within 3 minutes. The operation is convenient and efficient, which greatly improves the efficiency of drainage operation. A filter component is set inside the connecting pipe 11.

[0033] The filter assembly includes a filter screen 12, which effectively filters out sediment, debris, and other impurities in the water, preventing these impurities from entering the subsequent pipes and water storage tank 6, thus avoiding pipe blockage or affecting the siphon effect. The filter screen 12 is slidably connected inside the connecting pipe 11. A water pumping pipe 13 is fixedly connected to the bottom end of the filter screen 12. A disassembly and assembly assembly is provided on the outer wall of the water pumping pipe 13. The disassembly and assembly assembly includes a connecting ring 14. The inner wall of the connecting ring 14 is fixedly connected to the outer wall of the water pumping pipe 13. The connecting ring 14 contacts the inner wall of the connecting pipe 11, providing a certain sealing and positioning function. A connector 15 is fixedly connected to the bottom end of the connecting pipe 11. The outer wall of the connecting ring 14 is threadedly connected to the inside of the connector 15. This threaded connection method facilitates the quick disassembly and assembly of the water pumping pipe 13 and the connecting pipe 11, making it convenient to clean and maintain the filter screen 12.

[0034] Reference Figure 1 , Figure 4 and Figure 5 A fixing block 18 is fixedly connected to the outer wall of the water storage tank 6. A rotating shaft 19 is rotatably connected inside the fixing block 18. A slot 23 is opened inside the tank cover 17. A threaded column 20 is rotatably connected inside the rotating shaft 19. A knob 21 is fixedly connected to the top of the threaded column 20. The surface of the knob 21 is provided with anti-slip texture for easy rotation by the operator. A slider 22 is threadedly connected to the outer wall of the threaded column 20. A locking block 24 is fixedly connected to one side of the slider 22. The locking block 24 engages with the slot 23. When the knob 21 is rotated, the threaded column 20 rotates, driving the slider 22 to move, thereby causing the locking block 24 to engage or disengage from the slot 23 of the tank cover 17. This enables convenient fixing and opening of the tank cover 17, facilitating maintenance operations inside the water storage tank 6 and greatly improving the maintenance convenience of the device.

[0035] Working Principle: When using this self-priming valve well pumping device based on the siphon principle, firstly, connect the inlet pipe 1 to the connecting pipe 11 via connector 2. Then, assemble the pumping pipe 13 to the connecting pipe 11 via connecting ring 14 and connector 15, ensuring that the filter screen 12 is located inside the connecting pipe 11 to filter impurities in the water. Next, insert the pumping pipe 13 below the liquid level in the valve well, and simultaneously extend the drain valve 8 at one end of the corrugated pipe 9 to the lowest drainage point. Then, fill the tank with water by opening the sealed water inlet 4 on the tank cover 17 and injecting clean water into the storage tank 6. Check the water level through the observation window 7 and the scale line 16 until the water level reaches the upper limit of the observation window 7. Then, close the sealed water inlet 4 and confirm the seal. Then, start the siphon by turning the drain valve 8 to the fully open position. At this time, using the siphon principle, the clean water in the storage tank 6 will drive the air flow in the pipe. When a continuous water flow is observed at the outlet of the drain valve 8, immediately close the drain valve 8. A siphon is established. During the operation and monitoring phase, the observation window 7 confirms that there are no air bubbles accumulating in the water storage tank 6, ensuring the stability of the siphon. At the same time, the drainage valve 8 can be adjusted to control the drainage flow. If an abnormal situation occurs, the manual ventilation valve 5 on the top of the tank cover 17 can be operated to interrupt the siphon. When it is necessary to empty the water storage tank 6, the bottom vent valve 10 can be opened. This self-priming valve well pumping device based on the siphon principle is suitable for municipal emergency drainage valve well water intake, underground pipe gallery leakage, subway sump backflow, chemical plant underground tank area water accumulation, and substation cable trench drainage scenarios. It can treat wastewater containing weak acids and alkalis. In the scenarios of greenhouse drainage ditches and low-lying farmland water accumulation, it can be used in conjunction with the existing mobile water storage bag. A single siphon can drain 3-5 m³ / h (when the pipe diameter is DN65). It can also handle underground garage flooding after earthquakes and manhole backflow in flood-stricken areas. It meets the ISO22320 emergency management standard, can be airdropped for transport, and can operate stably in environments from -20℃ to 60℃.

[0036] In addition, the can lid 17 is connected to the fixing block 18 on the outer wall of the water tank 6 via a rotating shaft 19, a threaded post 20, a knob 21, a slider 22, and a locking block 24. Rotating the knob 21 drives the threaded post 20 to rotate, causing the slider 22 to move, thereby allowing the locking block 24 to engage or disengage from the locking groove 23 of the can lid 17, thus enabling convenient fixing and opening of the can lid 17 and facilitating maintenance and other operations inside the water tank 6.
