[0042] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0043] In related technologies, fluid pressurization is required in some scenarios. However, there are many limitations to fluid pressurization, leading to inconvenience or safety hazards in fluid transportation. For example, during firefighting operations, there may be situations where the floors requiring rescue are too high, preventing fluid from being delivered to the scene. The conventional approach is to modify fire trucks to increase the pressure they can deliver, enabling the fluid to be transported to higher floors, but this approach is costly. Similarly, fluid pressure is crucial in the transportation of natural gas or oil. Current practices involve establishing pressurization zones in areas far from the transportation zone, where the fluid is pressurized before transportation, which also increases transportation costs. Alternatively, electronic pressurization valve assemblies can be used to pressurize the fluid in the transportation area, but this poses significant safety risks for the transportation of natural gas, oil, and other fluids.

[0044] Based on this, see Figures 1 to 4 This disclosure provides a fluid self-driven pressurization device that can achieve self-driven pressurization and circulation of fluid. The pressurizing device includes a main housing 1, a connecting pipe 2, a circulation assembly 3, and a reversing assembly 5. The main housing 1 includes a first housing 11 and a second housing 12. The first housing 11 has an inlet end 111, an outlet end 112, and a pushing assembly 4. The inlet end 111 is used for fluid to enter, and the outlet end 112 is used for fluid to flow out. The first housing 11 contains the pushing assembly 4, which is used to push the fluid inside the first housing 11. The second housing 12 is connected to the first housing 11 and contains a pressurizing assembly 124, which is used to pressurize the fluid inside the second housing 12. One end of the connecting pipe 2 is connected to the outlet end 112, and the other end is connected to the second housing 12. The connecting pipe 2 is used to allow the fluid inside the second housing 12 to flow out through the outlet end 112. The circulation assembly 3 is configured to circulate the fluid within the first housing 11 and the second housing 12 under the action of the pushing assembly 4. The reversing assembly 5 is configured to move the pushing assembly 4 by moving the pressurizing assembly 124.

[0045] In this embodiment, fluid enters the first housing 11 through inlet 111. The fluid moves within the first housing 11 and then enters the second housing 12 through circulation assembly 3. When the fluid enters the second housing 12, its movement drives pressurizing assembly 124 to move, which pressurizes the fluid within the second housing 12. The pressurized fluid can then flow out through connecting pipe 2 at outlet 112, achieving the purpose of pressurizing the fluid (relatively small pressurization). Alternatively, the pressurized fluid can also enter the first housing 11 through reversing assembly 5. When the fluid enters the first housing 11, its movement drives pushing assembly 4 to move, which can repressurize the fluid. After repressurization, the fluid can flow out through outlet 112 (moderate pressurization). Or, the pressurized fluid can enter the second housing 12 through circulation assembly 3 for repressurization, thereby increasing the fluid flow pressure (larger pressurization). Thus, the pressurization device provided in this embodiment can pressurize fluids through multiple processes without relying too much on external conditions, thereby saving costs.

[0046] In some embodiments of this disclosure, see Figure 2 , Figure 3 The pressurization assembly 124 includes a pressurization column 1241; the second housing 12 has a pressurization chamber 121, and the pressurization column 1241 is slidably connected in the pressurization chamber 121. Part of the pressurization column 1241 causes the pressurization chamber 121 to form a first chamber 122, and part of the pressurization column 1241 causes the pressurization chamber 121 to form a second chamber 123. The volume of the second chamber 123 is larger than that of the first chamber 122. Specifically, when fluid enters the second housing 12, it pushes the pressurizing column 1241 within the second housing 12 to move. The volume of the second chamber 123 is larger than that of the first chamber 122. The fluid undergoes a volume change between the first and second chambers 122 and 123, increasing the pressure of the fluid within the second housing 12. The pressurized fluid then enters the first housing 11 through the reversing assembly 5. The pressurized fluid drives the pushing assembly 4 within the first housing 11 to move. The movement of the pushing assembly 4 allows the fluid in the first housing 11 to re-enter the second housing 12 through the circulation assembly 3 for further pressurization, thus achieving fluid pressurization. Simultaneously, under certain conditions, the pushing assembly 4 can drive the pressurized fluid out of the first housing 11 to achieve different levels of fluid pressurization, thereby meeting different pressure requirements.

[0047] In some embodiments of this disclosure, see Figure 1 , Figure 2The circulation component 3 includes a first circulation pipe 31 and a second circulation pipe 32. One end of the first circulation pipe 31 is connected to the first housing 11, and the other end of the first circulation pipe 31 is connected to the second housing 12. The pushing component 4 has a first state in which fluid in the first housing 11 enters the second housing 12 through the first circulation pipe 31. One end of the second circulation pipe 32 is connected to the first housing 11, and the other end is connected to the second housing 12. The pushing component 4 also has a second state in which fluid in the first housing 11 enters the first housing 11 through the second circulation pipe 32.

[0048] In some embodiments of this disclosure, see Figure 3 , Figure 4 The pushing assembly 4 includes a pushing rod 41 and a diverter 42. The first housing 11 has a pushing cavity, and the pushing rod 41 is slidably connected within the pushing cavity. The diverter 42 is disposed on the pushing rod 41 and is used to divert fluid flowing out of the first housing 11. It is understood that the diverter 42 can move with the pushing rod 41, thus giving the pushing assembly 4 a first state and a second state. Specifically, when the pushing rod 41 moves, it drives the diverter 42 to move. When the diverter 42 causes the pushing assembly 4 to be in the first state, the fluid in the first housing 11 can enter the second housing 12 through the first circulation pipe 31. When the diverter 42 causes the pushing assembly 4 to be in the second state, the fluid in the second housing 12 enters the first housing 11 through the second circulation pipe 32.

[0049] Furthermore, in this embodiment, the pushing component 4 also has a third state. The pushing component 4 drives the diverter 42 to move. When the diverter 42 causes the pushing component 4 to be in the third state, the fluid in the first housing 11 can be discharged through the outlet end 112, thus realizing the discharge of the pressurized fluid.

[0050] As an example, the flow divider 42 includes a flow divider block 421, a plurality of flow divider plates 422, and a blocking block 423; the first housing 11 has a flow divider channel 113, and the plurality of flow divider plates 422 divide the flow divider channel 113 into a first flow divider section 1131, a second flow divider section 1132, and a third flow divider section 1133; the flow divider block 421 is disposed within the flow divider channel 113; the flow divider block 421 has corresponding arrangements for the first flow divider section 1131, the second flow divider section 1132, and the third flow divider section 1133. A diversion orifice 4211 is provided; a blocking block 423 is disposed on the push rod 41, and the blocking block 423 can move with the push rod 41 so that the fluid flows out through the diversion orifice 4211 from one of the first diversion section 1131, the third diversion section 1133, or the second diversion section 1132; wherein, the first diversion section 1131 is connected to the first circulation pipe 31; the second diversion section 1132 is connected to the outlet end 112; and the third diversion section 1133 is connected to the second circulation pipe 32.

[0051] Specifically, in the initial state, the blocking block 423 can block the diversion holes 4211 corresponding to the second diversion section 1132 and the third diversion section 1133. When the fluid enters the first housing 11 through the inlet end 111, the fluid enters the second housing 12 through the first circulation pipe 31. The fluid then flows back into the first housing 11 after passing through the second housing 12 and the reversing assembly 5. Driven by the fluid in the first housing 11, the push rod 41 moves, which in turn drives the blocking block 423 to move. When the blocking block 423 blocks the first diversion section 1131 and the third diversion section 1133, the fluid in the first housing 11 flows out through the second diversion section 1132 (outlet end 112). When the blocking block 423 blocks the first diversion section 1131 and the second diversion section 1132, the fluid flows out of the third diversion section 1133 (and can enter the second housing 12 through the second circulation pipe 32); when the blocking block 423 blocks the second diversion section 1132 and the third diversion section 1133, the fluid flows out of the first diversion section 1131 (and can enter the second housing 12 through the first circulation pipe 31).

[0052] It should be noted that "fluid flows out through the diversion orifice 4211 from one of the first diversion section 1131, the third diversion section 1133, or the second diversion section 1132" means that the fluid can flow out through the first diversion section 1131, the third diversion section 1133, or the fluid can flow out through any one of the second diversion sections 1132.

[0053] In some embodiments of this disclosure, the reversing assembly 5 includes a first reversing pipe 51 and a second reversing pipe 52. One end of the first reversing pipe 51 is connected to a first chamber 122, and the other end of the first reversing pipe 51 is connected to one end of a first housing 11. The connection point between the first reversing pipe 51 and the first chamber 122 is not on the same side as the connection point between the first reversing pipe 51 and the first housing 11. This allows fluid from the first chamber 122 to flow into the first housing 11, thereby driving the operation of the actuating assembly 4 within the first housing 11. One end of the second reversing pipe 52 is connected to a second chamber 123, and the other end of the second reversing pipe 52 is connected to one end of the first housing 11. The connection point between the second reversing pipe 52 and the second chamber 123 is not on the same side as the connection point between the second reversing pipe 52 and the first housing 11. This allows fluid from the second chamber 123 to flow into the first housing 11, thereby driving the operation of the actuating assembly 4 within the first housing 11.

[0054] Furthermore, in this embodiment, the position where one end of the first reversing pipe 51 is connected to the first chamber 122 is not on the same side as the position where the other end of the first reversing pipe 51 is connected to the first housing 11, and the position where one end of the second reversing pipe 52 is connected to the second chamber 123 is not on the same side as the position where the other end of the second reversing pipe 52 is connected to the first housing 11. In this way, the outflow of fluid in the first chamber 122 or the second chamber 123 can be controlled, thereby controlling the movement direction of the push assembly 4.

[0055] In some embodiments of this disclosure, the orthographic projection of the first commutator 51 onto the main housing 1 overlaps with the orthographic projection of the second commutator 52 onto the main housing 1. This allows for a compact arrangement of the first commutator 51 and the second commutator 52 on the booster unit, helping to save floor space.

[0056] As an example, the first reversing pipe 51 and the second reversing pipe 52 are arranged in an "X" shape on the main housing 1. This allows the fluid to circulate and be pressurized in the pressurizing device while also making the pressurizing device relatively compact and reducing its floor space.

[0057] In some embodiments of this disclosure, see Figure 5 , Figure 6 The pressurization device also includes at least two sets of check valve components 6; the check valve component 6 includes a first check valve 61 and a second check valve 62; the first check valve 61 is connected to the first chamber 122, and the second check valve 62 is connected to the second chamber 123; wherein, the first check valve 61 is used to control the entry of external fluid into the second housing 12, and the second check valve 62 is used to control the discharge of fluid that enters the second housing 12 through the first check valve 61, and the first check valve 61 and the second check valve 62 are located on different sides in the same set of check valve components 6.

[0058] For example, when the fluid is a gas, it is often necessary to remove certain unwanted components from the gas during its transport. Thus, a fluid capable of removing these components can be introduced into the first chamber 122 or the second chamber 123 through the check valve assembly 6 to remove unwanted components from the fluid in the second housing 12.

[0059] Furthermore, the check valve assembly 6 can also relieve the pressure of the fluid in the second housing 12, keeping the fluid pressure within a suitable range. Specifically, when the fluid pressure is too high, it needs to be depressurized. This can be achieved by opening the first check valve 61 connected to the first chamber 122 and the second check valve 62 connected to the second chamber 123, allowing a portion of the fluid to be discharged from either the first chamber 122 or the second chamber 123, thus reducing the fluid pressure.

[0060] Furthermore, by placing the check valve components 6, which are in the same group, on different sides, it is possible to gradually reduce the pressure of the fluid during the decompression process.

[0061] In some embodiments of this disclosure, see Figure 1 , Figure 2 The pressurization device also includes multiple shut-off valves 7; some shut-off valves 7 are located on the first circulation pipe 31 and are used to control the fluid to enter the first circulation pipe 31 through the first diversion section 1131; some shut-off valves 7 are located on the second circulation pipe 32 and are used to control the fluid to enter the second circulation pipe 32 through the third diversion section 1133.

[0062] Specifically, when it is necessary to control the fluid to enter the second housing 12 through the first circulation pipe 31 instead of the second circulation pipe 32, the shut-off valve 7 corresponding to the first circulation pipe 31 can be opened and the shut-off valve 7 corresponding to the second circulation pipe 32 can be closed. In this case, the fluid in the first housing 11 will enter the second housing 12 through the first circulation pipe 31. Similarly, when it is necessary to control the fluid to enter the second housing 12 through the second circulation pipe 32 instead of the first circulation pipe 31, the shut-off valve 7 corresponding to the second circulation pipe 32 can be opened and the shut-off valve 7 corresponding to the first circulation pipe 31 can be closed. In this case, the fluid in the first housing 11 will enter the second housing 12 through the first circulation pipe 31.

[0063] In some embodiments of this disclosure, see Figure 1 The booster device also includes a mounting base 8. The mounting base 8 is provided to facilitate fixing the booster device in any position.

[0064] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
