[0019] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of the present application.
[0020] With reference to Figure 1 and Figure 2 In an embodiment, the oiling and exhausting device 100 comprises an oiling passage 101, an exhausting passage 102 and a sealing member 103. The oiling passage 101 is configured to communicate with the oil-receiving device 300. The exhausting passage 102 is configured to communicate with the oiling passage 101, and the exhausting passage 102 is provided with an exhaust port 1021. The sealing member 103 is arranged in the exhausting passage 102 and configured to open and close the exhaust port 1021. The gas is released from the exhausting passage 102 through the exhaust port 1021.
[0021] Specifically, the oil-receiving device 300 itself does not belong to the oiling and exhausting device 100, but is an object to which the oiling and exhausting device 100 is applied. For the convenience of description, the oil-receiving device 300 is numbered in the present application. Figure 2
[0022] In the embodiment, the oiling passage 101 forms an oiling cavity with both ends open, and the exhausting passage 102 forms an exhausting cavity with both ends open. The oiling cavity and the exhausting cavity are not the same cavity. The exhausting passage 102 communicates with the oiling passage 101, and the oil can flow between the exhausting passage 102 and the oiling passage 101. The oiling passage 101 is configured to communicate with the oil supply device 201 (see Figure 3 When the oil supply device 201 is used in the pressure oiling mode, the oiling speed is very fast, which can cause high pressure in the oiling and exhausting device 100 and the oil-receiving device 300. In addition, the speed of the oil in the oiling passage 101 flowing into the oil-receiving device 300 is slow, which can cause the liquid level of the oil in the oiling and exhausting device 100 to be higher than the liquid level of the oil in the oil-receiving device 300. The sealing member 103 seals the exhausting passage 102, and the exhausting passage 102 has the function of temporarily storing oil during the oiling process, thereby avoiding the leakage of oil from the exhaust port 1021 during the oiling process.
[0023] In the embodiment, the exhausting passage 102 is not always closed or opened. The closing and opening time can be designed according to the oiling law of the oiling and exhausting device 100 and the oil-receiving device 300, or the closing and opening time can be designed according to the oiling time or the pressure condition of the oiling and exhausting device 100, or the closing and opening of the sealing member 103 can be manually observed according to the rising or falling of the oil level in the exhausting passage 102.
[0024] In other embodiments, the oiling passage 101 and the exhaust passage 102 can be integrally formed, which can improve the overall strength of the oiling passage 101 and the exhaust passage 102 and accelerate the production efficiency of the oiling and exhaust device 100. The oiling passage 101 and the exhaust passage 102 can also be fixed by welding, clamping or other methods. The oiling passage 101 and the exhaust passage 102 can be connected vertically, or can be connected at any angle.
[0025] It should be noted that when the oiling and exhaust device 100 is in use, the exhaust passage 102 is located above the oiling passage 101. The gas can rise along the exhaust passage 102 and be discharged from the exhaust port 1021. The temporarily stored oil in the exhaust passage 102 can enter the oiling passage 101 under the action of gravity and finally enter the oil receiving device 300.
[0026] The oil receiving device 300 can be, for example, a motor, an engine, a transformer or other device. The oil in the oiling and exhaust device 100 can flow into the oil receiving device 300 to cool the elements in the oil receiving device 300 or flow into the oil storage cavity of the oil receiving device 300.
[0027] As can be seen from the above, the oiling and exhaust device 100 of the present application includes an oiling passage 101, an exhaust passage 102 and a sealing member 103. The oiling passage 101 is used to communicate with the oil receiving device 300. The exhaust passage 102 communicates with the oiling passage 101 and is provided with an exhaust port 1021. The sealing member 103 is arranged in the exhaust passage 102 and is used to open and close the exhaust port 1021. The gas is released from the exhaust port 1021 of the exhaust passage 102. The oiling and exhaust device 100 of the present application is low in cost and convenient to use. The opening or closing of the sealing member 103 can be achieved manually. The exhaust passage 102 is sealed by the sealing member 103, which has the function of temporarily storing oil. The oiling and exhaust device 100 of the present application can avoid the phenomenon of oil surge during pressure oiling and the leakage of oil when the oil level in the oiling and exhaust device 100 is higher than the oil level in the oil receiving device 300 for a short time.
[0028] In an embodiment, the oiling passage 101 includes an oil outlet end 1011, which is formed with an oil outlet (not shown in the figure). The oil outlet end 1011 is used to connect with the oil receiving device 300, and the oil outlet is used to communicate with the oil receiving device 300.
[0029] Specifically, the oil outlet end 1011 is connected to the oil receiving device 300, so that the oil in the oil filling channel 101 and the exhaust channel 102 can flow into the oil receiving device 300. In an actual application scenario, the sealing connector at the oil filling end of the oil receiving device 300 is removed, and the oil outlet end 1011 of the oil filling and exhaust device 100 is connected to the oil filling end of the oil receiving device 300. The connection can be manual or by a robot.
[0030] The oil filling channel 101 is a hollow structure, and the oil outlet is formed at the oil outlet end 1011. The oil in the oil filling channel 101 and the exhaust channel 102 flows into the oil receiving device 300 through the oil outlet. The oil receiving device 300 and the oil filling and exhaust device 100 are detachably connected. When the oil receiving device 300 needs to be filled with oil, the oil filling and exhaust device 100 is connected to the oil receiving device 300. When the oil in the oil filling and exhaust device 100 flows into the oil receiving device 300, the oil receiving device 300 and the oil filling and exhaust device 100 are detached, and the oil receiving device 300 is sealed at the oil filling end.
[0031] In an embodiment, the oil filling and exhaust device 100 includes a sealing hose 1012. One end of the sealing hose 1012 is sleeved on the oil outlet end 1011, and the other end of the sealing hose 1012 is used to connect to the oil receiving device 300.
[0032] Specifically, the sealing hose 1012 can be made of a flexible material such as rubber or resin, and the material of the sealing hose 1012 is not limited in the present application. The sealing hose 1012 has two opposite ends. One end is sleeved on the oil outlet end 1011, and the other end can be sleeved on or connected to the oil filling end of the oil receiving device 300. The sealing hose 1012 is used to seal the connection between the oil outlet end 1011 and the oil receiving device 300. When the oil receiving device 300 is filled with oil by the oil filling and exhaust device 100, the sealing hose 1012 can prevent oil leakage at the connection between the oil outlet end 1011 and the oil receiving device 300.
[0033] In other embodiments, in addition to using the sealing hose 1012 at the connection between the oil outlet end 1011 and the oil receiving device 300, a bolt seal or other structure can also be used, which is not limited in the present application.
[0034] In an embodiment, the oil outlet end 1011 has a chamfered structure.
[0035] Specifically, the oil outlet end 1011 is provided in a chamfered structure, which is beneficial for sleeving the oil outlet end 1011 into the sealing hose 1012. In other embodiments, the oil outlet end 1011 can be provided in a conical or cylindrical shape, which is not limited in the present application.
[0036] In an embodiment, the oiling channel 101 comprises an oil inlet end 1013, the oil inlet end 1013 is formed with an oil inlet, and the oil inlet end 1013 is configured to communicate with the oil supply device 201, and the oil inlet end 1013 is provided with an internal thread 1014.
[0037] Specifically, the oiling channel 101 comprises two ends arranged oppositely, one end is an oil outlet end 1011, and the other end is the oil inlet end 1013, and the oil inlet end 1013 communicates with the oil supply device 201. The oil inlet end 1013 is provided with an internal thread 1014, which can facilitate the connection of the oil inlet end 1013 and the oil supply device 201. When the oil supply device 201 supplies oil to the oil receiving device 300 through the oiling and exhausting device 100, the internal thread 1014 at the oil inlet end 1013 can prevent oil leakage at the connection between the oil inlet end 1013 and the oil supply device 201.
[0038] In other embodiments, in addition to using the internal thread 1014 at the connection between the oil inlet end 1013 and the oil receiving device 300, a bolt seal or other structure can also be used, which is not limited in the present application. In addition to providing the internal thread 1014 in the oil inlet end 1013, an external thread can also be provided on the outer wall of the oil inlet end 1013.
[0039] In an embodiment, the exhaust port 1021 is formed at one end of the exhaust channel 102 away from the oiling channel 101, and the sealing member 103 is rotationally connected to the exhaust channel 102 for rotationally opening or closing the exhaust port 1021.
[0040] Specifically, the exhaust channel 102 comprises two ends arranged oppositely, and the exhaust channel 102 is a hollow structure. When the sealing member 103 opens the exhaust port 1021, the gas in the oiling and exhausting device 100 and the oil receiving device 300 can be discharged to the atmosphere, so that the pressure of the oil receiving device 300 meets the requirements. When the sealing member 103 closes the exhaust port 1021, the exhaust port 1021 seals the oiling and exhausting device 100 and the oil receiving device 300, so that the gas in the oiling and exhausting device 100 and the oil receiving device 300 cannot be discharged to the atmosphere when the oil supply device 201 supplies oil to the oil receiving device 300 through the oiling and exhausting device 100, thereby preventing oil leakage during oiling.
[0041] In other embodiments, the sealing member 103 and the exhaust channel 102 can also be connected by clamping, screwing, etc., which is not limited in the present application.
[0042] In an embodiment, the oiling and exhausting device 100 further comprises a control member (not shown in the figure), the control member is connected to the sealing member 103 and is configured to control the opening and closing of the sealing member 103.
[0043] Specifically, the control member can be a MCU (Micro Control Unit), the control member is electrically connected with the sealing member 103, the control member sends a signal to the sealing member 103 to open or close the exhaust port 1021, and the sealing member 103 opens or closes the exhaust port 1021 under the control of the control member. The control member can improve the intelligence of the refueling exhaust device 100 in use and reduce manual operation.
[0044] Specifically, the refueling exhaust device 100 further comprises a motor (not shown in the figure), an output shaft of the motor is coaxially fixed with a rotating shaft of the sealing member 103, and the motor drives the sealing member 103 to rotate. The control member is electrically connected with the motor, and the control member can control the sealing member 103 by controlling the motor.
[0045] In other embodiments, the refueling exhaust device 100 can also not be provided with the control member, and a worker manually controls the sealing member 103 to open and close the exhaust port 1021.
[0046] In an embodiment, the refueling exhaust device 100 further comprises a timer (not shown in the figure), the timer is electrically connected with the control member, and the control member controls the sealing member 103 to open in response to the timer detecting that the refueling time reaches a time threshold.
[0047] Specifically, when the oil supply device 201 refuels the to-be-oiled device 300 through the refueling exhaust device 100, the timer starts timing and records the refueling time, and the control member controls the sealing member 103 to open when the timer detects that the refueling time reaches a time threshold. The gas in the refueling exhaust device 100 and the to-be-oiled device 300 can be discharged through the exhaust port 1021. The timer can be installed on the refueling exhaust device 100 or can be arranged on the oil supply device 201, which is not limited in the present application.
[0048] In an embodiment, the refueling exhaust device further comprises a pressure sensor (not shown in the figure), the pressure sensor is electrically connected with the control member, and the pressure sensor is arranged in the refueling exhaust device 100, and the control member controls the sealing member 103 to open in response to the pressure sensor detecting that the pressure drops to a pressure threshold. Specifically, the pressure sensor is arranged in the exhaust channel 102 or the refueling channel 101.
[0049] Specifically, the pressure sensor can be, for example, a piezoresistive pressure sensor or a strain gauge pressure sensor. This application does not limit the type of pressure sensor, and the pressure sensor can be set at any position within the refueling and venting device. The pressure sensor generates a signal to transmit the detected pressure value to the control unit. When the control unit determines that the pressure value has dropped to the pressure threshold, it generates a signal to open the seal 103 and transmits it to the seal 103. The seal 103 opens, allowing the gas in the refueling and venting device 100 and the oil-filling device 300 to be discharged, thereby stabilizing the pressure in the oil-filling device 300.
[0050] In one embodiment, the exhaust channel 102 has an indicator area, at least the material of the indicator area is a light-transmitting material.
[0051] Specifically, the material of the indicator area on the exhaust channel 102 is light-transmitting. The material of the exhaust channel 102 other than the indicator area can be light-transmitting or not. The staff can open or close the seal 103 by the indication of the indicator area on the exhaust channel 102.
[0052] In this design, when the indicator area is at the upper end, the upper end of the exhaust channel 102 is made of a light-transmitting material, allowing operators to open or close the seal 103 based on the presence and level of oil within the indicator area. Similarly, when the indicator area is at the lower end, the lower end of the exhaust channel 102 is made of a light-transmitting material, allowing operators to open or close the seal 103 based on the presence and level of oil within the indicator area. This application does not limit the location of the indicator area. The light-transmitting material can be, for example, light-transmitting plastic or resin; this application does not limit the type of light-transmitting material used.
[0053] See Figure 3 In one embodiment, the oil supply device 200 includes an oil supply device 201 and an oil filling and venting device 100 as described in any of the above embodiments, wherein the oil supply device 201 is connected to the oil filling and venting device 100.
[0054] Specifically, the oil supply device 201 can be, for example, a fuel nozzle or an oil tank. The oil supply device 201 can be connected to the refueling and gas supply device 100 by, for example, a threaded connection, a sealed hose connection, or it can be integrally formed. This application does not limit this.
[0055] The oil supply equipment 200 can be equipped with a quantitative refueling function. For example, a control system and a refueling shut-off valve can be installed in the oil supply equipment 200. The control system can control the refueling amount. When the refueling amount reaches a certain value, the control system controls the refueling shut-off valve to close. This allows for precise control of the refueling amount throughout the entire refueling process, making it suitable for different refueling devices.
[0056] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application.
