[0034] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0035] Reference will be made below Figures 1 - 6 to describe a combined energy accumulator according to an embodiment of the present application.

[0036] As Figure 1 and [[ID=1,6]] Figure 2 shown, the combined energy accumulator includes: a plurality of energy accumulator bodies 100 and two mounting seats 200;

[0037] As Figure 3 and Figure 4 shown, two ends of each of the energy accumulator bodies 100 are provided with connection heads 110, and a first guide through-hole 111 is formed laterally in each of the connection heads 110;

[0038] As Figure 4 shown, each of the mounting seats 200 includes a support part 210 and a crimping part 220. The support part 210 is provided with first arc-shaped grooves 211 at intervals, a second guide through-hole 2111 is formed on the inner wall surface of each of the first arc-shaped grooves 211, and a flow guiding channel 2112 communicating each of the second guide through-holes 2111 is formed in the support part 210; second arc-shaped grooves 221 are formed at intervals on the crimping part 220. The crimping part 220 can be mounted on the support part 210, and each of the second arc-shaped grooves 221 and the first arc-shaped grooves 211 enclose a space for accommodating the connection head 110, and the first guide through-hole 111 of the connection head 110 is communicated with the second guide through-hole 2111 of the first arc-shaped groove 211.

[0039] In specific implementation, first place the connectors 110 at both ends of the accumulator body 100 in the first arc grooves 211 of the two support parts 210, and ensure that the first guide through holes 111 of each connector 110 are aligned with the second guide through holes 2111 of the first arc grooves 211. Then install the crimping part 220 onto the support part 210. The second arc groove 221 of the crimping part 220 and the first arc groove 211 of the support part 210 enclose to form a space for accommodating the connectors 110 of the accumulator body 100. Finally, fix the crimping part 220 to the support part 210 by bolts or other fasteners to ensure that it will not loosen during operation.

[0040] The combined accumulator of the related art includes multiple accumulator bodies, a mounting base, and connecting pipes. The multiple accumulator bodies are interconnected through the connecting pipes, and the interconnected multiple accumulator bodies are fixed on the mounting base. In some cases, such as when the pressure fluctuation in the hydraulic system pipeline is small, too many accumulator bodies are idle and do not participate in the energy storage work, and it is inconvenient to disassemble these redundant accumulator bodies.

[0041] In the above embodiment of the present application, by setting the diversion channel 2112 in the support part 210 to replace the connecting pipes in the related art, when the pressure fluctuation in the hydraulic system pipeline is small, the redundant accumulator body 100 between the crimping part 220 and the support part 210 can be disassembled without having to remove the complex connecting pipes, greatly improving the convenience of disassembly and maintenance. On the contrary, when the pressure fluctuation in the hydraulic system pipeline is large, the number of accumulator bodies 100 can also be flexibly increased, enhancing the ability to cope with the system pressure fluctuation.

[0042] As Figure 5 shown, in some embodiments, a positioning short tube 112 is installed in the first guide through hole 111, one end of the positioning short tube 112 protrudes from the first guide through hole 111, and the first guide through hole 111 is communicated with the second guide through hole 2111 through the positioning short tube 112.

[0043] In this embodiment, by setting the positioning short tube 112 in the first guide through hole 111 and one end of the positioning short tube 112 protruding from the first guide through hole 111, on the one hand, it can ensure that the first guide through hole 111 and the second guide through hole 2111 can be accurately aligned and communicated; on the other hand, the positioning short tube 112 can also ensure good sealing at the connection between the first guide through hole 111 and the second guide through hole 2111, reducing the leakage risk that may occur at this connection.

[0044] In actual implementation, the second via hole 2111 is disposed on the bottom wall surface of the first arc-shaped groove 211, so that it is in the most stable position within the first arc-shaped groove 211 of the support portion 210. When the accumulator main body 100 is installed into the first arc-shaped groove 211 of the support portion 210, the alignment of the second via hole 2111 is carried out through the direct support of the bottom wall surface of the first arc-shaped groove 211. This design effectively enhances the force uniformity of the accumulator main body 100, enabling it to better withstand the high pressure in the hydraulic system and external impacts, and reducing the risk of loosening or misalignment of the second via hole 2111 caused by external forces or system pressure.

[0045] As Figure 4 and Figure 5 shown, in some embodiments, the support portion 210 is further provided with slots 212 at intervals, and an insertion strip 222 that cooperates with the slots 212 is formed between each of the second arc-shaped grooves 221 of the crimping portion 220.

[0046] In this embodiment, the cooperation between the slots 212 and the insertion strips 222 provides a more precise alignment and positioning function. When the crimping portion 220 is installed onto the support portion 210, the insertion strips 222 are naturally inserted into the slots 212, enabling a more stable connection between the crimping portion 220 and the support portion 210. This precise positioning method avoids misalignment between components and effectively improves the installation accuracy.

[0047] As Figure 1 and Figure 5 shown, in some embodiments, a strip-shaped hole 213 is formed on the side wall of the slot 212; the opening direction of the strip-shaped hole 213 is the same as the insertion direction of the insertion strip 222 along the slot 212; a locking bolt 230 is detachably installed on the insertion strip 222, and one end of the locking bolt 230 facing away from the insertion strip 222 penetrates through the strip-shaped hole 213 and presses against the support portion 210.

[0048] In this embodiment, the design of the strip-shaped hole 213 enables the locking bolt 230 to move within a certain range, allowing for fine adjustment of the insertion depth and position of the insertion strip 222. This flexible adjustment function makes the installation process more flexible.

[0049] Since the locking bolt 230 is of a detachable design, when maintenance or disassembly of the accumulator main body 100 is required, the operator only needs to loosen the locking bolt 230 to quickly separate the insertion strip 222 from the support portion 210. The strip-shaped hole 213 provides a moving space for the locking bolt 230, which makes the disassembly and assembly process more convenient, without the need for complex operations, greatly shortening the maintenance time and improving the work efficiency.

[0050] In actual implementation, elastic rubber pads are provided in the areas where the first arc-shaped groove 211 and the second arc-shaped groove 221 contact the connector 110. If the contact areas between the connector 110 and the first arc-shaped groove 211 and the second arc-shaped groove 221 are in hard contact, long-term operation may cause wear at the contact parts, affecting the connection stability and service life. The elastic rubber pads form a flexible isolation layer in the contact areas, reducing the hard-to-hard friction, thus effectively preventing the wear phenomenon caused by long-term contact and extending the service life of the accumulator system.

[0051] As Figure 6 shown, in some embodiments, the accumulator main body 100 includes: a housing 120, a bladder 130, and an inflation valve 140;

[0052] The connector 110 is provided at two ends of the housing 120. The bladder 130 is installed inside the housing 120. The inflation valve 140 is installed in the connector 110 at the top end of the housing 120, and the inflation valve 140 communicates with the bladder 130. A hydraulic channel 150 is provided in the connector 110 at the bottom end of the housing 120, and the hydraulic channel 150 communicates with the first through hole 111.

[0053] In this embodiment, on the hydraulic system pipeline, the staff inflates the bladder 130 through the inflation valve 140 to make it have a certain pressure. When the pressure in the hydraulic system pipeline increases, the liquid enters the housing 120 through the hydraulic channel 150 and squeezes the bladder 130, causing the volume of the bladder 130 to shrink and generating a restoring force. When the pressure in the hydraulic system pipeline decreases, the bladder 130 rebounds in the housing 120 and squeezes the liquid in the housing 120 through the hydraulic channel 150 into the hydraulic system pipeline, thus realizing energy storage.

[0054] As Figure 6 shown, in some embodiments, the combined accumulator further includes: a buffer valve 160;

[0055] The buffer valve 160 includes a valve core 161 and a downward pressing column 162 connected in sequence from top to bottom. The valve core 161 is located inside the housing 120. A spring 163 is sleeved on the downward pressing column 162, and a valve body seat 164 fixed in the hydraulic channel 150 is sleeved outside the spring 163.

[0056] In this embodiment, after the bladder 130 is inflated, it expands rapidly. When the bottom end of the bladder 130 contacts the valve core 161, it presses the valve core 161 to move downward, causing the bottom end of the valve core 161 to squeeze the spring 163 downward and move towards the bottom end of the valve body seat 164. Under the action of the spring 163, the downward expansion speed of the bladder 130 is buffered, avoiding the situation where the bladder 130 blocks the hydraulic channel 150.

[0057] In some embodiments, a notch is provided on the valve core 161 to enable the hydraulic passage 150 to communicate with the hydraulic passage 150.

[0058] In this embodiment, when the bladder 130 expands, even if the bladder 130 squeezes the valve core 161 and pushes the valve core 161 downward, the notch can ensure that the hydraulic passage 150 remains partially connected to the hydraulic system. This design avoids completely blocking the hydraulic passage 150 when the bladder 130 expands, ensuring that even when the bladder 130 expands to the limit, the liquid can still flow through the notch, maintaining the normal operation of the hydraulic system and avoiding the risk of system pressure loss or blockage.

[0059] In actual implementation, the end face of the end of the valve core 161 facing away from the hydraulic passage 150 is an arc surface.
