[0002] The hydraulic servo system is a closed-loop control system composed of a hydraulic power mechanism and a feedback mechanism, which is divided into two categories: mechanical hydraulic servo systems and electro-hydraulic servo systems. Among them, the hydraulic servo system is a closed-loop hydraulic control system, which usually has a box for storing the circulating liquid, such as the content shown in the patents with the authorization announcement numbers CN215058613U, CN216278778U, and CN217582707U. The inside of the box of the existing hydraulic servo system is usually a cavity, and the inflow and outflow of the liquid are completed in this cavity. After the circulating liquid has circulated for a long time, it usually contains more impurities, which affects the working efficiency of the hydraulic servo system. In addition, these impurities are evenly distributed inside the entire box, and a large space needs to be cleaned when cleaning. Therefore, a servo hydraulic tank that can block impurities to a certain extent and is convenient for cleaning is needed. Summary of the Invention

[0006] Further, the partition is vertically arranged inside the box; the bottom edge of the partition is connected to the bottom plate of the box bottom; there is a set distance between the top edge of the partition and the top plate of the box.

[0007] Further, at least one end of the two ends of the bottom edge of the partition has a gap for the liquid to flow through between it and the inner side wall of the box.

[0008] Further, an oil suction filter is also arranged on the outflow pipe, the oil suction filter is located inside the box, and the oil suction filter is arranged close to the bottom of the box.

It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0025] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present utility model. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation.

[0026] Embodiment 1:

[0027] As Figures 1 to 4 shown, a servo hydraulic tank that is convenient for cleaning includes a box body 1 for containing a circulating liquid. An outflow pipe 2 for the liquid to flow out and an inflow pipe 3 for the liquid to flow in are provided on the box body 1. After the circulating liquid flows into the box body 1 through the inflow pipe 3, it then flows out of the box body 1 through the outflow pipe 2 and is sent into a servo power structure outside the box body 1, and finally returns to the inflow pipe 3 to complete the cycle; a partition 4 is provided inside the box body 1, and the inflow pipe 3 and the outflow pipe 2 of the liquid are respectively located on both sides of the partition 4; the partition 4 divides the space inside the box body 1 into two parts, and the two parts are interconnected to help the liquid flow mutually in part of the areas; in this example, the partition 4 is vertically located inside the box body 1, and the bottom edge of the partition 4 is connected to the bottom plate of the box bottom; there is a set distance between the top edge of the partition 4 and the top plate of the box body 1 for the liquid to flow through to achieve the connection of the two parts; on the side of the partition 4 close to the inflow pipe 3, the inflowing liquid first precipitates on this side, and the relatively cleaner upper-layer liquid flows to the other side of the partition 4 and enters the external servo power structure through the outflow pipe 2. Additionally, when cleaning, only the side close to the inflow pipe 3 needs to be cleaned, reducing the cleaning space and facilitating cleaning; it should be noted that the inflow pipe 3 and the outflow pipe 2 are respectively arranged at positions inside the box body 1 far from the partition 4 to facilitate the precipitation of the liquid during the flowing process.

[0028] At least one end of the bottom edge of the partition plate 4 has a gap for liquid to flow between it and the inner side wall of the box body 1, so that when the liquid level of the liquid in the box body 1 is lower than the height of the partition plate 4, the liquid on both sides of the partition plate 4 can still flow smoothly; and to a certain extent, it blocks impurities, so that more impurities remain on the side of the partition plate 4 close to the inflow pipe 3.

[0029] An oil suction filter 21 is also provided on the outflow pipe 2. The oil suction filter 21 is located inside the box body 1 and is arranged close to the bottom of the box body 1; in this example, the oil suction filter 21 is horizontally laid down, so that the oil suction filter 21 can also be in full contact with the liquid at a low liquid level, ensuring the speed of oil suction and filtration.

[0030] A return oil filter 31 is provided on the inflow pipe 3. The return oil filter 31 is located inside the box body 1; in this example, the return oil filter 31 is vertically arranged inside the box body 1.

[0031] An air inlet 5 for balancing air pressure is also provided on the box body 1; a detachable sealing cover 51 is provided on the air inlet 5. Usually, the air inlet 5 is in a sealed state, and when it is necessary to balance air pressure, the sealing cover 51 is opened; an air inlet filter element 52 is provided on the side of the air inlet 5 inside the box body 1 to reduce impurities in the air from entering the box body 1.

[0032] A detachable sealing cleaning cover port 6 is also provided on the side of the box body 1. In this example, the cleaning cover port 6 is connected to the edge of the circular hole provided on the side of the box body 1 by screws. There are two cleaning cover ports 6 in total, and the two cleaning cover ports 6 are respectively arranged on both sides of the partition plate 4 to realize the cleaning of the spaces on both sides of the partition plate 4 inside the box body 1.

[0033] An oil drain pipe 7 for discharging the circulating liquid inside the box body 1 is provided at the bottom of the box body 1, which is convenient for cleaning the inside of the box body 1 after discharging the liquid; a switch valve 71 for controlling the on-off of the oil drain pipe 7 is provided on the oil drain pipe 7.

[0034] In the implementation process, by arranging a partition plate 4 inside the box body 1, impurities are mainly concentrated on the side of the partition plate 4 close to the inflow pipe 3, which is convenient for cleaning when cleaning the box body 1. In addition, it can also reduce the impurities flowing into the inflow pipe 3 and ensure the normal operation of the hydraulic servo system; by arranging a vertical partition plate 4, a precipitation area is formed on the side of the partition plate 4 close to the inflow pipe 3, making the impurities more concentrated; by arranging a gap between the bottom of the partition plate 4 and the inner side wall of the box body 1, the liquid can still flow normally when the liquid level in the box body 1 is lower than the partition plate 4, completing the liquid circulation.

[0035] The above description is only a specific example of the present utility model and does not constitute any limitation to the present utility model. Obviously, for professionals in the field, after understanding the content and principle of the present utility model, various modifications and changes in form and details may be made without departing from the principle and structure of the present utility model. However, these corrections and changes based on the idea of the present utility model are still within the scope of protection of the claims of the present utility model.
