Description

Technical Field

[0001] This utility model relates to the field of water hammer pump technology, and in particular to an automatic water lifting device that uses water potential energy without oil or electricity. Background Technology

[0002] The main body of a water hammer pump includes components such as pipelines, drain valves, central valves, and pressure tanks. Through the cooperation of the drain valves, central valves, and pressure tanks, and by utilizing the water hammer effect and atmospheric pressure, water is pumped out.

[0003] To prevent gas leakage from the pressure tank and subsequent malfunction, an air bladder is placed inside to store gas and prevent loss. However, the repeated expansion and contraction of the air bladder makes it prone to damage. Furthermore, when the input water pressure is too high, the air bladder can be over-compressed, leading to its failure. In the existing pressure tank structure, replacing the air bladder is inconvenient, as it is not easy to disassemble or inflate it, resulting in inconvenience in use. Utility Model Content

[0012] The water potential energy-based, oil-free, and electricity-free automatic water lifting device proposed in this utility model has the following advantages:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] Reference Figure 1 , Figure 2 , Figure 3 The water potential energy-based oil-free and electricity-free automatic water lifting equipment includes the main pipeline 1, and also includes:

[0022] The split pressure tank assembly includes a tank body 2 connected to the main pipeline 1. The upper end of the tank body 2 is open, and a tank cover 3 is fitted over the upper end of the tank body 2. A connection port 5 is integrally formed on the outer wall of the tank cover 3. An air bladder 6 is placed inside the tank body 2. An air bladder opening 7 is integrally formed on the upper end of the air bladder 6. The air bladder opening 7 can pass through the connection port 5 and extend to the outside of the tank cover 3. A connection cap 8 is fitted over the upper end of the connection port 5. The air bladder opening 7 abuts between the connection port 5 and the connection cap 8. An expansion tube 9 is connected to the upper end of the connection cap 8. One end of the expansion tube 9 is connected to an inflation port 10, which is a valve core.

[0023] Furthermore, refer to Figure 1 One end of the expansion tube 9 is also connected to a pressure gauge 11.

[0024] Furthermore, refer to Figure 2 The tank body 2 and the tank cover 3 are sealed and fixed by multiple sets of latches 4. The latches 4 can be the reverse latches 4 commonly used in the prior art.

[0025] Working principle:

[0026] When the water hammer pump is working, at the drain valve ( Figure 2 The main pipeline 1 is arranged longitudinally) and the central valve ( Figure 2 With the cooperation of the main pipeline 1 (which is set horizontally inside), a portion of the water is pumped into the tank 2. The air bladder 6 inside the tank 2 repeatedly contracts and expands to form a complete water hammer pump working cycle.

[0027] When it is necessary to replace the airbag component 6, unscrew the connecting cap 8 from the connecting port 5 so that the connecting cap 8 is no longer in contact with the airbag port 7. Then remove the lock 4 and remove the can lid 3 from the can body 2. At this time, the airbag component 6 will detach from the can body 2 together with the can lid 3. Pull the airbag component 6 forcefully so that the airbag port 7 is no longer in contact with the connecting port 5 to complete the disassembly.

[0028] Forcefully insert the air bladder opening 7 of the new airbag component 6 into the connection port 5, and then screw the connection cap 8 back into the connection port 5. During installation, ensure that the contact points between the air bladder opening 7, the connection port 5, and the connection cap 8 are flat. Then, place the airbag component 6 into the tank body 2 and secure the tank cover 3 to the tank body 2 using the locking buckle 4. Inflate the airbag through the inflation port 10. The air enters the expansion tube 9 through the inflation port 10, passes through the expansion tube 9, and enters the airbag component 6 through the air bladder opening 7. During inflation, observe the reading on the pressure gauge 11 to determine the air pressure status of the airbag component 6. After inflation, the replacement of the airbag component 6 is complete.

[0029] Example 2

[0030] To further improve safety and prevent airbag component 6 from bursting due to excessive pressure, refer to... Figure 4It also includes a pressure relief assembly, which includes a housing 12, which is connected to the expansion tube 9. A sliding rod 13 is slidably installed inside the housing 12. An abutment plate 14 is integrally formed on the inner wall of the housing 12. A sealing gasket 15 is fixedly installed at one end of the sliding rod 13. The sealing gasket 15 and the abutment plate 14 are in movable contact. A spring 16 is in movable contact between the sealing gasket 15 and the inner wall of the housing 12.

[0031] Furthermore, a limit cap 17 is threadedly installed on one side of the outer casing 12. The limit cap 17 abuts against the sliding rod 13 and is used to restrict the sliding rod 13 from moving freely.

[0032] Working principle:

[0033] When the inlet pressure is too high or the air pressure inside the airbag 6 is too high due to over-inflation, the high-pressure gas passes through the airbag opening 7 and the expansion tube 9 into the outer shell 12. The high-pressure gas inside the outer shell 12 pushes the sealing gasket 15 forward, the spring 16 is compressed, and the sealing gasket 15 is disengaged from the abutment plate 14. At this time, the high-pressure gas can be discharged outward.

[0034] When the sealing gasket 15 does not need to be detached from the abutment plate 14, the limiting cap 17 can be connected to the outer shell 12. At this time, due to the restriction of the limiting cap 17, the sliding rod 13 cannot extend outward, and the sealing gasket 15 cannot detach from the abutment plate 14, thus achieving the effect of disabling the function.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
