They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] This embodiment provides a pump unit refueling device to solve the technical problems existing in the prior art during pump unit maintenance, change the traditional lubricating oil filling method, replace the manual filling operation method, and improve the intelligence and digitalization of the lubricating oil filling field.

[0037] Specifically, such as Figures 1 to 5 As shown, a pump unit refueling device includes a mobile device, two oil tanks 20, an oil injection device 30, an intelligent oil control device 40, and a coil device 50. The mobile device includes a vehicle body 11, on which the two oil tanks 20 are arranged side by side. The two oil tanks 20 are used to hold different types of lubricating oil. The two oil tanks 20 store different grades of lubricating oil, which can meet the differentiated lubrication needs of various pump unit equipment without frequent cleaning and replacement of the oil tanks 20. At the same time, it avoids the mixing and contamination of different oils, improves the refueling flexibility and oil quality stability, and ensures the lubrication effect of the equipment.

[0038] The oil filling device 30 includes an oil filling port 31 and a plug 32. The oil filling port 31 is located at the top of the oil tank 20 and is connected to the oil tank 20. The plug 32 is used to seal the oil filling port 31. The oil filling port 31 provides a convenient channel for replenishing lubricating oil to the oil tank 20. The plug 32 seals the oil filling port 31 when not filling, preventing oil leakage and evaporation in the oil tank 20. At the same time, it prevents external dust, moisture and other impurities from entering and contaminating the oil, ensuring the quality of the oil and safe use.

[0039] The intelligent oil control device 40 is located above the oil tank 20. The intelligent oil control device 40 includes an intelligent pump 41, a touch display 42, and a controller 43. The inlet of the intelligent pump 41 is connected to the oil tank 20 via an oil guide pipe 411. The intelligent pump 41 is signal-connected to the controller 43, and the touch display 42 is communicatively connected to the controller 43. The touch display 42 provides manual touch operation, allowing the user to input the required oil quantity signal to the controller 43. The controller 43 then controls the operation of the intelligent pump 41 based on the adjustment signal. It should be noted that the touch display 42 can display the oil quantity and injection rate, which are standard functions of a display and will not be elaborated further.

[0040] The coil device 50 includes a hose 51, a filler nozzle 52, and a pipe clamp support 53. One end of the hose 51 is connected to the outlet connector 412 of the intelligent pump 41, and the other end of the hose 51 is connected to the filler nozzle 52. The pipe clamp support 53 is installed on the outer surface of the fuel tank 20. The filler nozzle 52 is fixed to the top of the fuel tank 20 by the pipe clamp support 53. The fixation of the filler nozzle 52 by the pipe clamp support 53 can keep the filler nozzle 52 neatly stored when not in use, avoiding damage caused by dragging or bending the hose 51 or oil residue dripping and polluting the environment. At the same time, it is convenient for quick access later, improving the convenience and standardization of refueling operations.

[0041] Based on the maintenance requirements of the pump unit, first confirm the appropriate lubricating oil grade and add it to the corresponding oil tank 20 through the filling port 31. During operation, move the portable oiling device 30 to the target pump unit, remove the oiling nozzle 52 from the pipe clamp support 53, accurately align it with the oil filling port of the pump unit, and insert it to fix it. Then, input the preset oiling amount on the touch display 42 according to the equipment maintenance standards. The controller 43 will immediately issue an instruction to drive the intelligent pump 41 to smoothly draw a quantitative amount of oil from the oil tank 20 and accurately deliver it to the pump unit through the hose 51. After the oil is added, the intelligent pump 41 automatically stops working. Simply return the oiling nozzle 52 to the pipe clamp support 53 to complete the entire oiling process. This intelligent refueling solution has completely revolutionized the traditional lubricating oil filling mode, replacing the crude method of manually lifting heavy oil drums and pouring them based on experience. It not only effectively solves problems such as oil spillage, inaccurate oil level control, and low refueling efficiency that are prone to occur in traditional operations, but also avoids the inconvenience and safety hazards of manual operation. At the same time, through digital settings and precise control, the refueling volume is traceable and manageable, which greatly improves the level of intelligence and digitalization in the field of lubricating oil filling and provides a strong guarantee for the standardized maintenance and efficient operation of pump unit equipment.

[0042] It should be noted that in this embodiment, in order to accommodate the filling of 22# lubricating oil and 46# lubricating oil, the number of oil tanks 20 is set to two. In other embodiments, the number of oil tanks 20 is set according to the specific actual situation. It should be noted that the number of oil filling devices 30, the number of intelligent oil control devices 40 and the number of coil devices 50 should be consistent with the number of oil tanks 20 and correspond one-to-one.

[0043] Furthermore, such as Figure 2As shown, the intelligent oil control device 40 also includes a liquid level sensor 44, which includes a probe 441 and a magnetic ring 442. The probe 441 is inserted into the oil tank 20 and is connected to the controller 43. The inner wall of the magnetic ring 442 is slidably connected to the outer peripheral wall of the probe 441. The density of the magnetic ring 442 is less than that of the lubricating oil. The magnetic ring 442 changes position accordingly with the rise and fall of the oil level and slides on the probe 441. The probe 441 feeds back the detected position signal of the magnetic ring 442 to the controller 43 in real time, and the current oil level information of the oil tank 20 is displayed on the touch display 42, thereby realizing accurate monitoring and control of the oil quantity, avoiding overflow due to excessive oil level or oil shortage due to excessive low oil level, and ensuring accurate and efficient refueling process.

[0044] Furthermore, the intelligent oil control device 40 also includes a first filter 45 and a one-way valve 46. Both the first filter 45 and the one-way valve 46 are connected to the inlet of the intelligent pump 41 through the oil guide pipe 411. The first filter 45 filters impurities in the oil to protect the intelligent pump 41, and the one-way valve 46 prevents the oil from flowing back. Together, they ensure that the oil entering the intelligent pump 41 is clean and the delivery is stable, avoiding pump wear or abnormal oil supply, thereby improving the reliability of the pump unit refueling device.

[0045] Furthermore, the intelligent oil control device 40 also includes a battery 47 and a handheld tablet 48. The battery 47 is detachably electrically connected to the controller 43, supplying power to the controller 43. When the battery 47 is depleted, a spare battery 47 can be plugged in and replaced, flexibly enabling battery replacement and charging. This avoids device shutdown due to battery depletion, ensuring continuous refueling operations in outdoor or power-free environments, while reducing maintenance costs and improving the controller 43's flexibility and battery reliability. The handheld tablet 48 is plugged in and can communicate with the controller 43. The handheld tablet 48 can be independently operated to set the required oil volume and display the current oil level in the tank 20, transmitting the refueling signal to the controller 43, which then controls the intelligent pump 41. The handheld tablet 48 can be unplugged from the controller 43, enabling remote setting of refueling parameters, real-time viewing of oil volume data, and monitoring of operational status. The refueling process can be completed without close-range operation, improving operational convenience and intelligence, while also facilitating data recording and subsequent traceability management.

[0046] Optionally, such as Figures 3 to 5As shown, the coil device 50 also includes a coil 54, a coil support 55, and a control valve 56. The coil support 55 is installed on the top of the oil tank 20, and the end of the coil support 55 is rotatably connected to the coil 54. The hose 51 is wound around the coil 54, achieving orderly storage and flexible extension of the hose 51, avoiding messy tangling, wear, or aging of the hose 51. It also facilitates adjusting the length of the hose 51 according to the refueling distance, improving operational convenience and device neatness. The hose 51 is connected to the refueling nozzle 52 through the control valve 56, precisely controlling the start / stop and flow rate of oil output, avoiding problems such as spillage or overfilling during refueling. It also facilitates operation interruption or emergency shutdown, ensuring the accuracy, safety, and standardization of the refueling process. In other embodiments, the coil device 50 includes a coil 54 and a coil support 55 or a control valve 56.

[0047] Optionally, the oil filling device 30 also includes a second filter. The side surface of the second filter is connected to the inner wall of the oil filling port 31. When adding lubricating oil, the second filter initially intercepts impurities and particulate matter in the oil to prevent contaminants from entering the oil tank 20 and contaminating the oil, thus ensuring the quality of the oil.

[0048] Optionally, the mobile device also includes multiple rollers 12, a handrail support 13, and a handrail 14. The multiple rollers 12 are evenly distributed on the bottom of the vehicle body 11 and are rotatably connected to the bottom of the vehicle body 11. The rollers 12 are equipped with a locking mechanism. After the mobile pump unit refueling device is moved to the designated position, the vehicle body 11 is locked by the locking mechanism to prevent movement during refueling and thus prevent oil leakage. One end of the handrail support 13 is fixedly connected to the side wall of the vehicle body 11, and the handrail 14 is installed at the other end of the handrail support 13. The oil injection device 30 is moved by pushing it from the left and right sides of the handrail, making the movement of the entire device more convenient. In this embodiment, the number of rollers 12 is 4. In other embodiments, the number of rollers 12 can also be 3, 5, or 6, etc.

[0049] Optionally, the pump unit refueling device also includes an oil draining device 60, which includes an oil drain port and a plug. The oil drain port is located at the bottom of the oil tank 20 and is connected to the oil tank 20 to drain the lubricating oil in the oil tank 20. The plug is used to seal the oil drain port. The oil drain port provides a convenient channel for oil replacement and residual oil discharge in the oil tank 20. When not draining oil, the plug seals the oil drain port to prevent oil leakage. At the same time, it facilitates the periodic removal of oil sediment impurities, ensuring the cleanliness of the oil and the safe use of the oil tank 20.

[0050] Furthermore, the pump unit's refueling device also includes a breather valve 70, which is located on the top of the oil tank 20 and is connected to the oil tank 20. The breather valve 70 automatically adjusts the air pressure balance inside and outside the oil tank 20 to prevent the oil tank 20 from deforming under negative pressure or leaking under positive pressure due to temperature changes or changes in oil volume. At the same time, it prevents moisture and impurities in the air from entering the oil tank 20 and contaminating the lubricating oil, thus ensuring the safety of the oil tank 20 and the quality of the lubricating oil.

[0051] Furthermore, such as Figure 5 As shown, the pump unit refueling device also includes a collection trough 80. The wall of the collection trough 80 is fixedly connected to the side surface of the oil tank 20. It is used to place tools such as wrenches and rags that need to be used when adding lubricating oil. The bottom of the collection trough 80 is provided with multiple through holes 81. Oil on the wrench or water on the rag drips through the through holes 81, preventing them from accumulating in the collection trough 80 and affecting the reuse of tools such as wrenches and rags.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
