Obviously, the drawings in the following description are only some embodiments of the present application, and those of ordinary skill in the art can also obtain other drawings based on these drawings without creative efforts.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0056] Please refer to the following Figure 1 , Figure 1 , which is a flowchart of a radiator control method provided by an embodiment of this application.

[0057] The specific steps may include:

[0058] S101: Control the radiator motor to rotate forward to drive the hydraulic oil to circulate between the radiator body and the fuel tank;

[0059] Among them, this embodiment can be applied to the controller of the device where the radiator is located. The above radiator includes a radiator body and a radiator motor, and the radiator body is connected to the fuel tank. When the radiator motor works, it can drive the hydraulic oil to circulate between the radiator body and the fuel tank. The radiator body is the main place for heat exchange. Through the internal pipes and external fins, the heat in the fuel tank is transferred to the environment. Specifically, the radiator motor is an electric motor that drives the heat dissipation pump. By rotating forward, it pushes the hydraulic oil to circulate between the radiator body and the fuel tank.

[0060] Before this step, there may be an operation of receiving a start instruction. At this time, the device where the radiator is located performs the corresponding operation, and the radiator motor in the radiator rotates forward to drive the hydraulic oil to circulate between the radiator body and the fuel tank.

[0061] S102: Detect the oil temperature of the hydraulic oil in the fuel tank;

[0062] Among them, in this embodiment, a temperature sensor can be set inside the fuel tank to detect the oil temperature of the hydraulic oil inside the fuel tank.

[0063] S103: If the oil temperature is greater than or equal to the preset temperature value, determine whether there is a fault in the radiator;

[0064] Among them, before this step, there may be an operation to determine whether the oil temperature of the hydraulic oil in the fuel tank is greater than or equal to a preset temperature value. If the oil temperature is greater than or equal to the preset temperature value, it indicates that there is a fault or fouling in the radiator. When the oil temperature is greater than or equal to the preset temperature value, in this embodiment, it is determined whether there is a fault in the radiator. The above-mentioned faults may include radiator motor faults, sensor faults, control system faults, connecting pipeline faults, etc. If there is a fault in the radiator, the process can be ended and a fault prompt message can be output; if there is no fault in the radiator, the relevant operations of S104 can be entered. The fouling mentioned in this embodiment does not belong to a fault.

[0065] S104: If there is no fault in the radiator, obtain the state parameters of the radiator;

[0066] Among them, this step is based on the premise that there is no fault in the radiator. At this time, the state parameters of the radiator can be obtained. The above-mentioned state parameters are parameters describing the fouling state of the radiator. The above-mentioned state parameters include the temperature difference, and may also include the air pressure difference. The temperature difference is the difference between the inlet oil temperature and the outlet oil temperature of the radiator, and the air pressure difference is the difference between the outlet air pressure and the inlet air pressure of the radiator.

[0067] As a feasible implementation manner, the temperature difference is equal to the value obtained by subtracting the outlet oil temperature from the inlet oil temperature, and the air pressure difference is equal to the value obtained by subtracting the inlet air pressure from the outlet air pressure.

[0068] S105: Determine whether the state parameters are within the abnormal range; if so, enter S106; if not, end the process;

[0069] Among them, fouling reduces the effective heat transfer area and decreases the heat exchange capacity, resulting in a decrease in the difference between the inlet oil temperature and the outlet oil temperature. Fouling increases the resistance of air flow, resulting in an increase in the pressure difference between the inlet and outlet of the air. The smaller the temperature difference, the higher the fouling degree of the radiator; the greater the air pressure difference, the higher the fouling degree of the radiator. In this embodiment, a critical temperature value corresponding to the temperature difference can be set, or a critical air pressure difference corresponding to the air pressure difference can be set.

[0070] When the state parameter includes the temperature difference, if the temperature difference is greater than or equal to the critical temperature value, it indicates that the state parameter is not within the abnormal range; if the temperature difference is less than the critical temperature value (such as the first value), it indicates that the state parameter is within the abnormal range.

[0071] When the state parameter includes the air pressure difference, if the air pressure difference is less than or equal to the critical air pressure difference, it indicates that the state parameter is not within the abnormal range; if the air pressure difference is greater than the critical air pressure difference (such as the third value), it indicates that the state parameter is within the abnormal range.

[0072] If the status parameter is not within the abnormal range, it indicates that the fouling degree of the radiator is less than or equal to the critical degree, and the process can be ended; if the status parameter is within the abnormal range, it indicates that the fouling degree of the radiator is greater than the critical degree, and a cleaning operation is performed.

[0073] S106: Control the radiator motor to rotate in the reverse direction to remove the fouling in the radiator.

[0074] Among them, this step is based on the status parameter being within the abnormal range. At this time, the fouling in the radiator can be removed by controlling the radiator motor to rotate in the reverse direction. As a feasible implementation manner, this embodiment can control the radiator motor to rotate in the reverse direction at the highest speed. The fouling in the radiator can include impurities such as dust, oil stains, and soot.

[0075] In this embodiment, by controlling the radiator motor to rotate forward, the hydraulic oil is driven to circulate between the radiator body and the fuel tank, ensuring that the heat is transferred from the fuel tank to the radiator and dissipated into the environment through the radiator. This embodiment detects the oil temperature of the hydraulic oil in the fuel tank, and when the oil temperature is greater than or equal to the preset temperature value and the radiator has no faults, the status parameters of the radiator are obtained, such as the temperature difference and / or the wind pressure difference. This embodiment determines whether the obtained status parameter is within the abnormal range; if the status parameter is within the abnormal range, it indicates that there is no fouling in the radiator; if the status parameter is not within the abnormal range, it indicates that there is fouling in the radiator, and at this time, the radiator motor can be controlled to rotate in the reverse direction. The reverse rotation of the radiator motor can generate an eddy current effect, which helps to remove the fouling inside the radiator and restore its heat dissipation performance. Therefore, this embodiment can automatically detect the status of the radiator and improve the service life of the radiator.

[0076] As a further introduction to Figure 1 the corresponding embodiment, when the status parameter is within the abnormal range, a specific timing can be selected to control the radiator motor to rotate in the reverse direction, specifically as follows: Detect whether the key switch of the device where the radiator is located is turned off; if so, control the radiator motor to rotate in the reverse direction for a preset duration; after the reverse rotation of the radiator motor is completed, turn off the device power to turn off the engine. The above process can perform cleaning during the delayed engine shutdown stage, avoiding interference with normal operation during the cleaning process.

[0077] As a further introduction to Figure 1 the corresponding embodiment, if the status parameter includes a temperature difference, it can be determined whether the temperature difference is less than a first value; if so, it is determined that the status parameter is within the abnormal range.

[0078] Correspondingly, this embodiment can further determine whether the temperature difference is less than a second value; if so, it is determined that the radiator is in the manual cleaning state, and a prompt message corresponding to the manual cleaning state is generated; if not, it is determined that the radiator is in the automatic cleaning state, and a prompt message corresponding to the automatic cleaning state is generated. Wherein, the second value is less than the first value. The automatic cleaning state refers to the state where the dirt can be removed by reversing the rotation of the radiator motor, and the manual cleaning state refers to the state where the dirt can be removed by reversing the rotation of the radiator motor and combining manual treatment.

[0079] As a further introduction to Figure 1 the corresponding embodiment, if the state parameter includes the wind pressure difference, it can be determined whether the wind pressure difference is greater than a third value; if so, it is determined that the state parameter is within the abnormal range;

[0080] Correspondingly, this embodiment can further determine whether the wind pressure difference is greater than a fourth value; if so, it is determined that the radiator is in the manual cleaning state, and a prompt message corresponding to the manual cleaning state is generated; if not, it is determined that the radiator is in the automatic cleaning state, and a prompt message corresponding to the automatic cleaning state is generated. Wherein, the fourth value is greater than the third value.

[0081] If the temperature difference is greater than or equal to the first value and the wind pressure difference is less than or equal to the third value, it means that the degree of dirt on the radiator is less than or equal to the critical degree, and no cleaning operation is required.

[0082] As a further introduction to Figure 1 the corresponding embodiment, the following method can be used to determine whether there is a fault in the radiator:

[0083] Method 1: Obtain the current current value of the heat dissipation pump solenoid valve; obtain the current rotation speed value of the radiator motor; determine whether the current current value matches the current rotation speed value; if not, it is determined that the radiator has a fault. Wherein, the heat dissipation pump solenoid valve is used to adjust the rotation speed of the radiator motor by controlling the displacement of the heat dissipation hydraulic pump; this embodiment can pre-store the corresponding relationship between the current value of the heat dissipation pump solenoid valve and the rotation speed value of the radiator motor.

[0084] Method 2: Obtain the current current value of the heat dissipation pump solenoid valve; obtain the current pipeline pressure of the oil inlet pipeline connecting the radiator motor and the heat dissipation hydraulic pump; determine whether the current current value matches the current pipeline pressure; if not, it is determined that the radiator has a fault. Wherein, the heat dissipation pump solenoid valve is used to control the displacement of the heat dissipation hydraulic pump; this embodiment can pre-store the corresponding relationship between the current value of the heat dissipation pump solenoid valve and the current pipeline pressure of the oil inlet pipeline.

[0085] The following describes the process described in the above embodiments through examples in actual applications.

[0086] After the independent cooling system of a large excavator has been used for a long time, the radiator becomes dirty and damaged, and its heat dissipation capacity will decline. At present, there is no detection method for the degree of radiator fouling. Only when the operator observes that the hydraulic oil is overheated during operation, will manual reverse cooling fans or water flushing be used for cleaning. At this time, the fouling is often relatively serious, and cleaning is very difficult or it is hard to clean thoroughly. At the same time, there is no monitoring and warning for the decline in the radiator heat dissipation capacity caused by problems in other links of the cooling system. When problems occur, the cooling system cannot be maintained quickly and simply, resulting in a reduction in work efficiency. This system uses a new type of radiator and a cooling monitoring system to be able to monitor the status of each key link of the radiator and the cooling system in real time, issue a warning when abnormal, and perform automatic cleaning or prompt manual intervention, solving the problems of difficult maintenance and repair of the cooling system, and improving the service life and simplicity of the cooling system.

[0087] Please refer to Figure 2 , Figure 2 FIG. is a schematic structural diagram of an excavator radiator maintenance system provided by an embodiment of the present application. The system includes: a controller, an instrument, a hydraulic tank temperature sensor, a cooling pump solenoid valve, a forward and reverse solenoid valve, a radiator assembly, a radiator motor speed sensor, an outlet temperature sensor, and an inlet temperature sensor. The cooling pump solenoid valve is used to control the displacement of the cooling hydraulic pump, thereby controlling the speed of the hydraulic motor. In this embodiment, a matching correspondence between the current value and the speed can be preset in advance. The radiator motor speed sensor, the outlet temperature sensor, and the inlet temperature sensor are arranged on the radiator assembly and connected to the controller.

[0088] This solution divides the radiator into three working states: normal working state, automatic cleaning state, and manual cleaning state.

[0089] During the operation of the excavator, when the hydraulic tank temperature sensor monitors that the temperature of the hydraulic oil does not reach the preset temperature point, the radiator is in the normal working state.

[0090] When the hydraulic oil temperature reaches the preset point (i.e., the preset temperature value), the controller compares whether the current of the cooling pump solenoid valve matches the speed value of the radiator motor speed sensor on the radiator assembly. If they do not match, the instrument will prompt a cooling system failure. If they match, the controller reads the temperature difference between the inlet temperature sensor and the outlet temperature sensor on the radiator assembly. When the temperature difference is less than or equal to the preset value 1 (i.e., the first value) and greater than the preset value 2 (i.e., the second value), during shutdown, the forward and reverse solenoid valve is controlled to reverse the radiator motor for a preset duration for radiator cleaning, and the instrument will display that the radiator enters the self-cleaning state at this time.

[0091] The machine has a delayed shutdown setting. If the detected temperature difference is less than or equal to preset value 1 and greater than preset value 2, it will not shut down immediately after the key switch is turned off. At this time, the radiator will immediately reverse, and the machine will wait for the radiator reverse to complete before the controller disconnects the power supply and shuts down. The above shutdown refers to the shutdown of the excavator, that is, the key switch is powered off, the engine shuts down, and the overall machine power supply is disconnected.

[0092] Further, when the hydraulic oil temperature reaches the preset point, the controller compares whether the current of the cooling pump solenoid valve matches the rotational speed value of the radiator motor speed sensor on the radiator assembly. If they do not match, the instrument will prompt a cooling system failure. If they match, the controller reads the temperature difference between the inlet temperature sensor and the outlet temperature sensor on the radiator assembly. When the temperature difference is less than or equal to preset value 2, during shutdown, the forward and reverse solenoid valve is controlled to reverse the radiator motor for a preset duration to clean the radiator. At the same time, the instrument warns and reminds the operator to manually clean the radiator, and the instrument displays that the radiator enters the manual cleaning state at this time.

[0093] Please refer to Figure 3 , Figure 3 which is a flowchart of a method for cleaning the radiator of an excavator provided by an embodiment of the present application. The process is as follows: Determine whether the fuel tank temperature reaches the preset point; if so, whether the current value of the cooling pump solenoid valve matches the rotational speed value of the cooling motor. If they do not match, the instrument will prompt a cooling system failure; if they match, determine whether the radiator temperature difference (i.e., the temperature difference between the inlet and outlet) is less than or equal to preset value 1. If it is not less than preset value 1, end the process; if it is less than preset value 1, determine whether the radiator temperature difference is less than or equal to preset value 2. If it is less than or equal to preset value 2, the radiator will automatically reverse for a preset duration during shutdown, and the instrument will warn the radiator and remind that the radiator enters the manual cleaning state; if it is greater than preset value 2, the radiator will automatically reverse for a preset duration during shutdown, and the instrument will display that the radiator enters the self-cleaning state.

[0094] In this embodiment, the radiator inlet and outlet temperature sensors are used to monitor the radiator status, the cooling system status is confirmed by comparing the current of the cooling pump solenoid valve and the rotational speed of the cooling motor, and the radiator status is also confirmed by comparing the temperature difference, and reverse self-cleaning and manual cleaning reminders are performed.

[0095] In this embodiment, the inlet and outlet temperature sensors can be assembled in other inlet and outlet oil circuits. In this solution, the radiator assembly integrally integrates the installation of temperature sensors at the hydraulic oil inlet and outlet positions. The temperature sensors do not necessarily have to be installed on the radiator, but can also be installed on the pipeline connectors of the inlet and return oil pipes, such as the interface position of the return oil pipe at the fuel tank. The matching of the solenoid valve current of the above-mentioned heat dissipation pump and the rotation speed of the heat dissipation motor can be implemented by means of oil circuit pressure and so on. In this embodiment, the rotation speed of the heat dissipation motor is monitored by a rotation speed sensor of the heat dissipation motor, and then compared with the solenoid valve current of the heat dissipation pump, which is more accurate in this way. When the heat dissipation motor is working, at different rotation speeds, the oil inlet pipeline pressure connecting the heat dissipation motor and the heat dissipation pump is inversely proportional to the solenoid valve current value of the heat dissipation pump and directly proportional to the rotation speed of the heat dissipation motor. The larger the solenoid valve current value of the heat dissipation pump, the smaller the pressure value, and the lower the rotation speed of the heat dissipation motor. Therefore, the rotation speed of the heat dissipation motor can be indirectly determined by establishing a relationship between the solenoid valve current value of the heat dissipation pump and the pressure value, and the oil circuit pressure value can be obtained through a pressure sensor and compared with the current preset value of the solenoid valve of the heat dissipation pump. The above-mentioned radiator status monitoring can also be optimized by adding the pressure difference between the inlet and outlet. The above-mentioned pressure difference between the inlet and outlet refers to the pressure difference between the inlet and outlet of the radiator, that is, the air pressure difference between the front and back when the radiator is working. In this embodiment, the heat dissipation motor can be reversed just after starting the engine or during the starting and stopping of the engine.

[0096] This embodiment can monitor the status of each key link of the radiator and the heat dissipation system in real time, issue a warning when abnormal, and perform automatic cleaning or prompt manual intervention, solving the problems of difficult maintenance and repair of the heat dissipation system, and improving the service life and simplicity of the heat dissipation system.
