Abstract
Description
Technical Field
[0001] This application relates to the field of energy storage technology, specifically to a diaphragm-detachable energy storage device. Background Art
[0002] An accumulator is an energy storage device in a hydraulic or pneumatic system. It converts energy in the system into compressed or potential energy at appropriate times and stores it. When the system needs it, it converts the compressed or potential energy back into hydraulic or pneumatic energy to replenish the system. When the system pressure increases instantaneously, it can absorb this energy to ensure the overall system pressure remains normal.
[0003] Existing accumulator diaphragms are usually fixed inside the casing and cannot be removed. When the diaphragm is damaged, the entire accumulator needs to be replaced, which increases the cost of using the accumulator. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a diaphragm-removable accumulator, which has the advantages of allowing the diaphragm to be removed from the housing for replacement when it is damaged, eliminating the need to replace the entire accumulator and reducing the operating cost of the accumulator. This solves the problem that existing accumulators typically have the diaphragm fixed inside the housing and cannot be removed, requiring the entire accumulator to be replaced when the diaphragm is damaged, thus increasing the operating cost of the accumulator.
[0005] To achieve the goal of replacing the diaphragm by removing it from the housing when it is damaged, without replacing the entire accumulator and reducing the operating cost of the accumulator, this application provides the following technical solution: A diaphragm-detachable accumulator, comprising an upper housing, an inflation valve at the top of the upper housing, a threaded connection between the outer surface of one end of the upper housing and the inner wall of one end of the lower housing, a connecting ring on the inner wall of the lower housing, a threaded connection between the outer surface of one end of the connecting ring and one side of the inner wall of the fixing sleeve, a diaphragm on the lower surface of the fixing sleeve, and a mounting base at the bottom of the diaphragm.
[0006] The above solution utilizes a threaded connection between a fixed sleeve and a connecting ring. Rotating the fixed sleeve allows it to separate from the connecting ring, causing the diaphragm to separate from the connecting ring. This allows the diaphragm to be removed from the housing when damaged, eliminating the need to replace the entire accumulator and reducing operating costs.
[0007] Furthermore, a sealing gasket is provided on the upper surface of the connecting ring, with the outer top of the sealing gasket located below the bottom of the upper housing and the inner top of the sealing gasket located below the bottom of the fixing sleeve.
[0008] The above scheme allows the upper and lower housings to be sealed together by setting a sealing gasket, making the gas chamber a closed cavity. The sealing gasket, together with the fixing sleeve, prevents the gas chamber above the diaphragm from communicating with the liquid chamber below.
[0009] Furthermore, the inner wall of the middle part of the upper shell is a gas cavity, which is a sealed cavity formed by the upper shell in conjunction with the sealing gasket and the diaphragm.
[0010] The above solution can prevent air leakage from the gas chamber, which would prevent the gas chamber from working properly. At the same time, the deformation of the diaphragm caused by hydraulic oil can compress the air in the gas chamber.
[0011] Furthermore, the inner wall of the middle part of the lower housing is a liquid cavity, which is a sealed cavity formed by the lower housing in conjunction with the sealing gasket and the diaphragm.
[0012] With the above scheme, when the pressure in the hydraulic system drops, the gas in the gas chamber can push the diaphragm to deform and smoothly push the hydraulic oil back into the hydraulic system's oil circuit. At the same time, the sealing of the liquid chamber can prevent the hydraulic oil from leaking out.
[0013] Furthermore, a limiting plate is installed on the inner wall of the middle part of the mounting base, and the limiting plate is connected to the mounting base by a thread.
[0014] With the above solution, when the diaphragm is damaged and needs to be replaced, the limiting plate can be removed from the mounting base through the threaded connection between the limiting plate and the mounting base, eliminating the need to replace the limiting plate as well, thus reducing the cost of replacing the diaphragm.
[0015] Furthermore, a connecting post is provided at the bottom of the limiting plate, and a guide block is provided at the bottom of the connecting post. The guide block is tapered, and one end of the guide block is slidably connected to the inner wall of the middle part of the guide ring.
[0016] The above scheme allows the guide block to work with the guide ring to guide the expansion direction of the diaphragm through its tapered design.
[0017] Furthermore, a connecting pipe is provided at the bottom of the inner wall of the lower housing, and oil-repellent holes are opened around the bottom of the connecting pipe.
[0018] The above solution allows the hydraulic oil at the bottom of the inner wall of the lower housing to be smoothly discharged from the oil outlet at the bottom of the inner wall of the lower housing.
[0019] Furthermore, a guide ring is provided at the top of the connecting pipe, and the guide ring is funnel-shaped.
[0020] The above scheme allows the funnel-shaped arrangement of the guide ring to increase the guiding angle of the guide block, thereby enabling more stable guidance of the diaphragm's expansion direction through the guide block.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This diaphragm-detachable accumulator uses a fixed sleeve and a connecting ring connected by threads. Rotating the fixed sleeve separates it from the connecting ring, causing the fixed sleeve to separate the diaphragm from the connecting ring. This allows the fixed sleeve to remove the diaphragm from the housing, enabling it to be removed and replaced when damaged, without needing to replace the entire accumulator, thus reducing the operating cost of the accumulator.
[0023] This type of diaphragm-detachable accumulator guides the expansion direction of the diaphragm through a guide block and guide ring. The limiting plate can accurately contact the top of the guide ring, thereby ensuring that the limiting plate and guide ring precisely protect the diaphragm. This prevents the exposed part of the diaphragm from contacting the bottom oil outlet of the lower housing due to the expansion angle, which would cause wear to the diaphragm and affect its lifespan.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0033] Please see Figure 2 , Figure 3 and Figure 5 A diaphragm-detachable accumulator in this embodiment includes an upper housing 1, an inflation valve 2 on the top of the upper housing 1, an outer surface of one end of the upper housing 1 threadedly connected to the inner wall of one end of the lower housing 3, a connecting ring 4 on the inner wall of the lower housing 3, an outer surface of one end of the connecting ring 4 threadedly connected to one side of the inner wall of the fixing sleeve 5, a diaphragm 6 on the lower surface of the fixing sleeve 5, and a mounting base 7 at the bottom of the diaphragm 6.
[0034] Please see Figure 2 and Figure 3 A sealing gasket 14 is provided on the upper surface of the connecting ring 4. The outer top of the sealing gasket 14 is located below the bottom of the upper housing 1, and the inner top of the sealing gasket 14 is located below the bottom of the fixing sleeve 5. The sealing gasket 14 can seal the connection between the upper housing 1 and the lower housing 3, making the gas chamber 15 a closed cavity. The sealing gasket 14, together with the fixing sleeve 5, can prevent the gas chamber 15 above the diaphragm 6 from communicating with the liquid chamber 16 below.
[0035] Please see Figure 2 and Figure 3 The inner wall of the middle part of the upper shell 1 is a gas chamber 15. The gas chamber 15 is a sealed cavity formed by the upper shell 1, the sealing gasket 14 and the diaphragm 6. This can prevent the air in the gas chamber 15 from leaking out and causing the gas chamber 15 to malfunction. At the same time, the deformation of the diaphragm 6 caused by the hydraulic oil can compress the air in the gas chamber 15.
[0036] Please see Figure 2 and Figure 3 The inner wall of the middle part of the lower housing 3 is a liquid cavity 16. The liquid cavity 16, together with the lower housing 3, sealing gasket 14 and diaphragm 6, forms a sealed cavity. The gas in the gas cavity 15 can push the hydraulic oil back into the oil circuit of the hydraulic system when the diaphragm 6 is deformed. At the same time, the sealing of the liquid cavity 16 can prevent the hydraulic oil from leaking out.
[0037] Please see Figure 4 , Figure 5 and Figure 6A limiting plate 8 is installed on the inner wall of the middle part of the mounting base 7. The limiting plate 8 is connected to the mounting base 7 by a thread. When the diaphragm 6 is damaged and needs to be replaced, the limiting plate 8 can be removed from the mounting base 7 by the threaded connection between the limiting plate 8 and the mounting base 7, without having to replace the limiting plate 8 together, thus reducing the cost of replacing the diaphragm 6.
[0038] Please see Figure 3 , Figure 5 and Figure 6 The bottom of the limiting plate 8 is provided with a connecting post 9, and the bottom of the connecting post 9 is provided with a guide block 10. The guide block 10 is tapered, and one end of the guide block 10 is slidably connected to the inner wall of the middle part of the guide ring 12. The tapered shape of the guide block 10 allows the guide block 10 to cooperate with the guide ring 12 to guide the expansion direction of the diaphragm 6.
[0039] Please see Figure 2 and Figure 3 A connecting pipe 11 is provided at the bottom of the inner wall of the lower housing 3. Oil drain holes 13 are opened around the bottom of the connecting pipe 11. The oil drain holes 13 allow the hydraulic oil at the bottom of the inner wall of the lower housing 3 to be discharged smoothly from the oil outlet at the bottom of the inner wall of the lower housing 3.
[0040] Please see Figure 2 , Figure 3 and Figure 5 A guide ring 12 is provided at the top of the connecting pipe 11. The guide ring 12 is funnel-shaped. The funnel-shaped design of the guide ring 12 can increase the guiding angle of the guide block 10, thereby more stably guiding the expansion direction of the diaphragm 6 through the guide block 10.
[0041] In this embodiment, a diaphragm-detachable accumulator is provided. The fixing sleeve 5 is threadedly connected to the connecting ring 4. Rotating the fixing sleeve 5 can separate the fixing sleeve 5 from the connecting ring 4, causing the fixing sleeve 5 to separate the diaphragm 6 from the connecting ring 4. This allows the fixing sleeve 5 to remove the diaphragm 6 from the housing. When the diaphragm 6 is damaged, it can be removed from the housing for replacement without replacing the entire accumulator, thus reducing the operating cost of the accumulator.
[0042] It should be noted that the sealing of the gas chamber 15 and the liquid chamber 16 can be adjusted by the inflation valve 2 and the oil passage below the lower housing 3.
[0043] The working principle of the above embodiment is as follows: Gas is filled into the gas chamber 15 through the inflation valve 2, and hydraulic oil enters the liquid chamber 16 through the oil passage at the bottom of the lower housing 3. When the pressure of the hydraulic system rises instantaneously, a large amount of hydraulic oil enters the liquid chamber 16. The large amount of hydraulic oil entering the liquid chamber 16 will cause the diaphragm 6 to deform, compressing the gas in the gas chamber 15. When the pressure of the hydraulic system drops instantaneously, the diaphragm 6 will expand under the pressure of the gas in the gas chamber 15. When the diaphragm 6 expands, it will push the hydraulic oil from the liquid chamber 16 to the oil passage. The hydraulic oil at the bottom of the inner wall of the lower housing 3 will be discharged through the oil vent 13. When the diaphragm 6 expands, the guide block... One end of guide block 10 will contact the inner wall of guide ring 12, allowing one end of guide block 10 to slide on the inner wall of guide ring 12. This allows guide block 10 to cooperate with guide ring 12 to guide the expansion direction of diaphragm 6, so that limiting plate 8 can accurately contact guide ring 12. When diaphragm 6 needs to be replaced, rotate upper housing 1 to remove upper housing 1 from lower housing 3, rotate fixing sleeve 5 to separate fixing sleeve 5 from connecting ring 4, remove diaphragm 6 from lower housing 3, rotate connecting column 9 to remove limiting plate 8 from mounting base 7, install limiting plate 8 into mounting base 7 at the bottom of new diaphragm 6, install fixing sleeve 5 on connecting ring 4, and reinstall upper housing 1 onto lower housing 3.
