Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

[0038] In the automobile production process, air supply and exhaust equipment is widely used in production areas such as spray rooms, drying furnaces and factories for exhaust; the air supply and exhaust equipment is mainly powered by fan equipment. In order to ensure the normal operation of the fan equipment, it is necessary to regularly perform maintenance operations such as filling lubricating oil on the fan equipment. However, in the actual production process, researchers found that fan equipment generally runs at full load for a long time and is rarely shut down; but when filling lubricating oil into the fan equipment, it is usually necessary to shut down the fan equipment and wait until the fan equipment stops completely before filling it. After the lubricating oil is filled, the equipment needs to be restarted. In other words, the fan equipment needs to be started and stopped repeatedly during maintenance, which will generate additional energy consumption and increase production costs. It should be noted that after filling the fan equipment with lubricating oil, the purpose of restarting the fan equipment is to ensure that the lubricating oil can flow smoothly through each lubrication point and discharge the air in the oil circuit, thereby ensuring the normal use of the fan equipment after filling the lubricating oil. Furthermore, when adding lubricating oil to the fan equipment, workers need to wait on site for the fan equipment to completely stop before adding lubricating oil, which wastes workers' working hours and increases labor costs.

[0039] The present invention provides a refueling device and an automatic refueling method, aiming to solve the technical problem of high production cost caused by the need to shut down fan equipment for maintenance.

[0040] See also Figure 1 and Figure 2In one embodiment of the present invention, the refueling device 1 is applied to a fan device, and the fan device includes a fan body 2, a motor body 3 and a power supply 4. The fan body 2 is provided with a first oil filling port 21, the motor body 3 is provided with a second oil filling port 31, and a conductive wire 41 is provided between the power supply 4 and the motor body 3. In an embodiment of the present invention, the motor body 3 is a three-phase motor, and the conductive wire 41 is connected to one of the U phase, V phase and W phase of the three-phase motor. It should be noted that when the fan device is shut down, the current in the conductive wire 41 will gradually decrease to 0A; for example: when the fan device is shut down, the current in the conductive wire 41 of the three-phase motor will gradually decrease from 100A to 0A.

[0041] The refueling device 1 of the present invention comprises a base 100, an oil storage tank 200, a controller 300, an oil pump 400, a battery 500, an oil distributor 600 and a mutual inductor 700. The oil storage tank 200, the controller 300 and the battery 500 are all arranged on the base 100. The oil pump 400 is arranged in the oil storage tank 200 and is used to pump lubricating oil. The oil distributor 600 is connected to the oil pump 400, and the oil distributor 600 is provided with a first oil delivery pipe 610 and a second oil delivery pipe 620. The first oil delivery pipe 610 is detachably arranged at the first oil filling port 21. The second oil delivery pipe 620 is detachably arranged at the second oil filling port 31; the mutual inductor 700 is detachably sleeved on the conductive wire 41; the mutual inductor 700, the oil pump 400, and the battery 500 are all electrically connected to the controller 300; the controller 300 can receive and measure the current transmitted by the mutual inductor 700 in real time, obtain the measurement data, and control the operation of the oil pump 400 when the measurement data is less than the preset value, and the oil pump 400 delivers the lubricating oil in the oil storage tank 200 to the first oil filling port 21 and the second oil filling port 31 through the oil separator 600.

[0042] In the technical solution of the present invention, by providing a mutual inductor 700 detachably mounted on the conductive wire 41, a first oil delivery pipe 610 detachably mounted on the first oil filling port 21, and a second oil delivery pipe 620 detachably mounted on the second oil filling port 31, the refueling device 1 can be connected to the fan device when the fan device is running, and lubricating oil can be automatically added to the fan device at the beginning of the fan device shutdown to complete the refueling work; it does not need to repeatedly start and stop the fan device, and does not need to wait manually on site, which can reduce production costs and labor costs. In this embodiment, the oil storage tank 200 is used to store lubricating oil, the battery 500 is used to power the controller 300, the oil distributor 600 is used to evenly distribute the lubricating oil pumped by the oil pump 400 to each oil filling port, and the mutual inductor 700 is used to measure the current in the conductive wire 41. Among them, the mutual inductor 700 can be detachably mounted on the conductive wire 41, the first oil pipe 610 of the oil separator 600 can be detachably installed on the first oil filling port 21 through a quick connector, and the second oil pipe 620 of the oil separator 600 can be detachably installed on the second oil filling port 31 through a quick connector. That is to say, the mutual inductor 700 can be mounted on the conductive wire 41 and can be removed from the conductive wire 41, while the first oil pipe 610 and the second oil pipe 620 can be installed on or removed from the corresponding oil filling port. Specifically, when filling lubricating oil, workers can, before shutting down the fan equipment, sleeve the mutual inductor 700 on the conductive wire 41, install the first oil pipe 610 to the first oil filling port 21, and install the second oil pipe 620 to the second oil filling port 31 to complete the connection between the refueling device 1 and the fan equipment; and after the heating device is connected to the fan equipment, the mutual inductor 700 can transmit the current generated by it to the controller 300, and the controller 300 can receive and measure the current transmitted by the mutual inductor 700 in real time to obtain the measurement data; when the fan equipment is shut down, the current in the conductive wire 41 will gradually decrease until the measurement data is less than the preset value, and the controller 300 will control the oil pump 400 to run, and the oil pump 400 will deliver the lubricating oil in the oil storage tank 200 to the first oil filling port 21 and the second oil filling port 31 through the oil separator 600 to complete the filling of lubricating oil for the fan equipment.

[0043] It should be noted that the refueling device 1 is used to add lubricating oil to the fan equipment at the beginning of the shutdown of the fan equipment. That is to say, when the refueling device 1 completes the filling of lubricating oil, the fan equipment is still in the shutdown process, that is, the fan equipment is still running at a certain speed, and with the operation of the fan equipment, the lubricating oil can smoothly flow through each lubrication point, and the fan equipment can also discharge the air in the oil circuit. Therefore, by using the refueling device 1 to add lubricating oil when the fan equipment is shut down, there is no need to restart the fan equipment, which can reduce energy consumption and save production costs; at the same time, the filling of lubricating oil does not require workers to wait on site, which can save labor costs. In an embodiment of the present invention, it is defined that when the three-phase motor is operating normally, the measurement data of the mutual inductor 700 obtained by the controller 300 is α, and the preset value can be 80% of α, for example: when α=100A, the preset value is 80A. In addition, the mutual inductor 700 is an electrical device based on the principle of electromagnetic induction; specifically, when current flows through the conductive wire 41, the conductive wire 41 will generate an alternating magnetic field, and the winding in the mutual inductor 700 will be affected by the alternating magnetic field, thereby generating current and transmitting the generated current to the controller 300.

[0044] See also Figure 3 and Figure 4In one embodiment of the present invention, the mutual inductor 700 includes a first fastening member 710 and a second fastening member 720; one side of the first fastening member 710 is rotatably connected to one side of the second fastening member 720, and the other side of the first fastening member 710 is engaged with the other side of the second fastening member 720; the mutual inductor 700 includes a fastening state and an open state; when the mutual inductor 700 is in the fastening state, the other side of the first fastening member 710 is engaged with the other side of the second fastening member 720, and the first fastening member 710 and the second fastening member 720 are in contact and enclosed to form a through hole 730 for the conductive wire 41 to pass through; when the mutual inductor 700 is in the open state, the other side of the first fastening member 710 is separated from the other side of the second fastening member 720, and the first fastening member 710 and the second fastening member 720 are arranged at an angle. In an embodiment of the present invention, the mutual inductor 700 includes a first fastening member 710 and a second fastening member 720 that are rotatably connected. The first fastening member 710 and the second fastening member 720 can be arranged to form a through hole 730 for the conductive wire 41 to pass through; at the same time, they can be arranged at an angle so that the conductive wire 41 can be separated from the mutual inductor 700 from the space at the angle between the two. In other words, by driving the first fastening member 710 and the second fastening member 720 to rotate relative to each other, the mutual inductor 700 can be mounted on the conductive wire 41 or removed from the conductive wire 41, which can reduce the difficulty of workers disassembling the mutual inductor 700. Specifically, when connecting the refueling device 1 to the fan equipment, the worker can switch the mutual inductor 700 to an open state, and place the conductive wire 41 in the angle space between the first fastening member 710 and the second fastening member 720, and then drive the first fastening member 710 and the second fastening member 720 to rotate relative to each other, so that the mutual inductor 700 is switched to a fastened state, and the mutual inductor 700 can be mounted on the conductive wire 41; and when the refueling device 1 is used up and the mutual inductor 700 is removed, the worker only needs to switch the mutual inductor 700 from a fastened state to an open state, and move the conductive wire 41 out of the angle space between the first fastening member 710 and the second fastening member 720, and the mutual inductor 700 can be removed.

In the embodiment of the present invention, the through hole 730 is surrounded by the first groove 7111 of the first shell 711 and the second groove 7211 of the second shell 721, which can provide sufficient space for the conductive wire 41 to pass through. When the mutual inductor 700 is in a snap-fit ​​state, the two ends of the first conductive block 712 respectively abut against the two ends of the second conductive block 722 to form a ring-shaped conductive block; specifically, when the mutual inductor 700 is sleeved in the conductive wire 41, along with the operation of the motor body 3, current will flow through the conductive wire 41, and an alternating magnetic field will be generated around it, and the part of the conductor 723 wound around the second conductive block 722 (i.e., the winding) will be affected by the alternating magnetic field, thereby generating current, and transmitting the generated current to the controller 300; thereby, the controller 300 can receive and measure the current transmitted by the mutual inductor 700.

[0046] In an embodiment of the present invention, the first housing 711 is provided with a first end face 7112 facing the second housing 721, and the second housing 721 is provided with a second end face 7212 facing the first housing 711; both ends of the first conductive block 712 extend out of the first end face 7112 and / or both ends of the second conductive block 722 extend out of the second end face 7212. In an embodiment of the present invention, both ends of the first conductive block 712 extend out of the first end face 7112, or both ends of the second conductive block 722 extend out of the second end face 7212, which can ensure that when the mutual inductor 700 is switched to the buckled state, the first conductive block 712 and the second conductive block 722 can abut against each other and form a ring-shaped conductive block.

[0047] In an embodiment of the present invention, the first fastening member 710 is provided with a protrusion, the second fastening member 720 is provided with an extension block 724, and the extension block 724 is provided with a snap-in hole 7241; when the mutual inductor 700 is in the snap-in state, the protrusion snaps into the snap-in hole 7241.
