Abstract
Description
Technical Field
[0001] The utility model is applied to the technical field of ultra-high voltage energy storage, and particularly relates to an ultra-high voltage energy storage device. Background Art
[0002] With the continuous advancement of science and technology, various products are beginning to move towards automated production. In the food production sector, automated equipment is replacing manual production and assembly operations. This not only reduces labor costs but also prevents contact between products and workers or the external environment, thereby preventing contamination. During the production and packaging process of such products, pressure maintenance and stabilization are required. During the pressure maintenance process, energy is stored in several high-pressure accumulators. The stored energy pressure is then used to output pressure to the product, making the output pressure more stable. Currently, high-pressure accumulators on the market mainly have a fixed connection between the hopper body and the plug, and the plug and hopper body are sealed by a sealing ring. This high-pressure accumulator seal can only be input from one side. When the pressurized hopper needs to reach ultra-high pressure, the sealing ring will deform under long-term ultra-high pressure operation. The high-pressure fluid will overflow from the edge of the sealing ring, resulting in pressure release and a short service life. If an ultra-high pressure accumulator with a simple structure, modular design, and easier assembly can be designed, and a contoured sealing structure is used to enhance the sealing performance to achieve ultra-high pressure sealed energy storage, the above problems can be solved. Utility Model Content

[0017] like Figures 1 to 6As shown, in this embodiment, the utility model includes an energy storage tube 1 and a high-pressure plug 2, both ends of the energy storage tube 1 are provided with a plug mounting port 3, and the middle part of the energy storage tube 1 is also provided with a high-pressure energy storage channel 4, two groups of high-pressure plugs 2 are connected to the plug mounting ports 3 at both ends of the energy storage tube 1 and are connected and communicated with the high-pressure energy storage channel 4, the high-pressure plug 2 includes a plug body 21 and a locking end cover 22, the plug end of the plug body 21 cooperates with the plug mounting port 3, and the locking end cover 22 cooperates with the connecting end of the plug body 21, the water inlet end of the plug body 21 is provided with a water inlet 5, and the middle part of the plug body 21 is also provided with a high-pressure channel 6, the two ends of the high-pressure channel 6 are respectively connected and communicated with the water inlet 5 and the high-pressure energy storage channel 4, and the water inlet 5 at both ends of the energy storage tube 1 is connected to an external high-pressure pipe. It can be seen that the energy storage tube 1 is set as a double plug connection structure, which can switch the connection at will. The plug body 21 is fixed to the plug installation port 3 through the locking end cover 22. When one end is used as the water inlet and the other end is used as the water outlet, the installation operation is simpler, the structure is simple, and the applicability is strong.
[0018] like Figure 2 and Figure 6 As shown, in this embodiment, the middle portion of the locking end cap 22 is provided with a limiting opening 7, the connecting end of the plug body 21 is limitedly engaged with the limiting opening 7, and one side of the locking end cap 22 is connected to the connecting end of the plug body 21 via a plurality of set screws 8. Thus, it can be seen that while the plurality of set screws 8 secure the locking end cap 22 to the plug body 21, when the plurality of set screws 8 are tightened, the locking end cap 22 partially deforms, thereby making the press fit and seal between the high-pressure plug 2 and the plug installation opening 3 tighter.
[0019] like Figures 2 to 4 As shown, in this embodiment, the plug body 21 is provided with a sealing step 23 at the plug end, and a sealing slope 9 is provided at the connection between the high-pressure energy storage channel 4 and the plug mounting opening 3. The sealing step 23 conforms to the sealing slope 9. As can be seen, the conformal fit between the sealing step 23 and the sealing slope 9 achieves a metal-to-metal hard seal with a small sealing gap, which is less likely to cause leakage when subjected to ultra-high-pressure water flow.
[0020] like Figure 3 As shown, in this embodiment, the cross-sectional diameter of the plug end of the plug body 21 is smaller than the inner diameter of the plug mounting opening 3. A drainage groove 10 is provided between the outer side of the plug end of the plug body 21 and the plug mounting opening 3. The locking end cap 22 is engaged with the inner side of the plug mounting opening 3. Therefore, if some high-pressure fluid leaks, the liquid can be stored in the drainage groove 10 and does not flow out of the ends of the energy storage tube 1.
[0021] like Figure 2 and Figure 3 As shown, in this embodiment, the outer edges of both ends of the energy storage tube 1 are provided with drainage holes 11, and the drainage holes 11 are connected and communicated with the plug installation opening 3. It can be seen that the liquid stored in the drainage groove 10 flows out through the drainage holes 11.
[0022] like Figure 3 As shown, in this embodiment, the water inlet 5 is concentrically arranged with the high-pressure energy storage channel 4, and the inner diameter of the water inlet 5 is smaller than the inner diameter of the high-pressure energy storage channel 4. Therefore, when high-pressure water flows into one end of the energy storage tube 1, the high-pressure fluid flows from the smaller water inlet 5 into the larger high-pressure energy storage channel 4 during the inflow process, thereby avoiding uneven pressure inside the high-pressure energy storage channel 4 caused by excessive flow.
[0023] The working principle of the present utility model is as follows: before starting the equipment, the high-pressure plugs 2 at both ends of the energy storage tube 1 are respectively connected to the water inlet and water outlet of the external pressurizing equipment, and the external pressurizing equipment is started. The high-pressure water flows from the high-pressure channel 6 at the water inlet into the high-pressure energy storage channel 4, and the water outlet of the external pressurizing equipment is closed. The internal pressure of the energy storage tube 1 increases to reach a predetermined pressure to achieve an energy storage effect. When a pressure maintaining operation is required, the water outlet of the external pressurizing equipment is opened, and the high-pressure liquid inside the high-pressure energy storage channel 4 flows out from the energy storage tube 1 and flows into the water outlet of the external pressurizing equipment through the high-pressure channel 6, thereby realizing ultra-high-pressure energy storage and pressurization of the equipment.
[0024] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
