DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0025] As Figures 1 to 6As shown in the utility model provides a kind of oil tank adapting to swing working condition, including tank 1, oil inlet cover plate 2, baffle 7, check valve 8, oil inlet cover plate 2 is located on the upper surface of tank 1, oil inlet cover plate 2 is equipped with oil inlet pipe 4 that extends into the bottom surface of oil tank, baffle 7 has four, vertically and is fixed to the bottom of oil tank, baffle 7 surrounds the oil inlet cover plate 2 and forms oil inlet area A, baffle 7 mutually contact and fixedly connected between baffle 7;The part except the oil inlet area A in oil tank is communication area B;Check valve 8 is equipped on baffle 7, and is located in oil inlet area A, check valve 8 only allows oil to flow from communication area B to oil inlet area A.

[0026] The internal volume of oil tank is used to store oil, and the baffle 7 has two functions: first, it separates the oil that would otherwise impact the tank 1, reducing the impact of the oil on the tank 1; second, it separates the oil inlet area A from the communication area B; the check valve 8 allows oil to flow in one direction, i.e., oil can only flow from the communication area B to the oil inlet area A. Even if the oil tank is in a swinging and tilted state, oil will not flow from the oil inlet area A to the communication area B, allowing the oil inlet pipe 4 to maximize the intake of oil.

[0027] The tank 1 includes a bottom plate 17, side plates 12, and a tank cover 13. The oil inlet cover plate 2 is openably arranged on the tank cover 13. The side plates 12 have four upper and lower flanges. The upper flanges are welded to the tank cover 13, and the lower flanges are welded to the bottom plate 17. In the swinging working condition, oil will impact the side plates 12, even causing water hammer effect. By adding flanges to the side plates 12, the overall rigidity of the oil tank is better than that of a flat side plate 12.

[0028] One end of the baffle 7 is elongated and fixedly connected to the side plate 12. The baffles 7 do not penetrate each other, and the part of the baffle 7 located in the communication area B is provided with a plurality of liquid passing holes 9. The size of each baffle 7 is determined according to the size of the oil tank. Although the baffles 7 divide the communication area B into different compartments, oil can flow between each compartment through the liquid passing holes 9. When the oil tank is in a swinging working condition, the baffles 7 can also reduce the impact of the oil in the oil tank.

[0029] As shown in the utility model, Figure 6 The check valve 8 includes a valve seat 15 fixedly embedded in the baffle 7, and a valve cover 16 hinged to the valve seat 15. The valve cover 16 is opened upward. At least one check valve 8 is arranged in the lower part of the baffle 7 in the oil inlet area A. When the oil is static, the valve cover 16 naturally droops by its own gravity. When the oil has a tendency to flow to the communication area B, the valve cover 16 is pressed to achieve relative sealing of the oil inlet area A. When the oil has a tendency to flow to the oil inlet area A, the valve cover 16 is opened by the oil, and the oil flows into the oil inlet area A, ensuring that the oil inlet pipe 4 can intake oil.

[0030] In this embodiment, the oil inlet cover 2 is equipped with an oil inlet 3, an air filter 5, and a level gauge 6. The oil inlet 3 is connected to the oil inlet pipe 4, the air filter 5 is externally connected to an oil pump, and the level gauge 6 is electrically connected to the oil pump. When the oil level is lower than a first set value, the level gauge 6 outputs a control signal to control the oil pump to add oil to the tank; conversely, when the oil level is higher than a second set value, the oil pump stops adding oil to maintain sufficient oil in the tank. The oil enters the tank after being filtered by the air filter 5. Changes in the oil level in the tank will cause changes in the pressure inside the tank. The air filter 5 is connected to the outside environment and plays a role in balancing the pressure in the tank while filtering the oil.

[0031] The tank cover 13 is also equipped with an oil return cover 10, which has an oil return port 11 extending into the oil tank. The oil return cover 10 is located in the connecting area B. Unused oil in the engine returns to the oil tank through the oil return port 11. This oil is at a high temperature and may carry impurities. By separating the oil inlet cover 2 and the oil return cover 10 into different areas by the partition 7, the impurities in the oil will settle at the bottom of the connecting area B, reducing the amount entering the oil inlet area A. The oil enters the oil inlet area A only after being cooled by the connecting area B. Therefore, placing the oil return cover 10 and the oil inlet cover 2 in different areas can achieve the functions of heat dissipation and sedimentation of impurities in the oil.

[0032] The fuel tank is also equipped with a drain port 14, which is located at the bottom of the fuel tank and adjacent to the return oil cover plate 10. When the fuel tank is maintained regularly, the fuel needs to be drained. The return oil port 11 has the most impurities. Placing the drain port 14 near the return oil cover plate 10 can make the impurities drain more thoroughly.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
