[0050] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0051] like Figure 1 As shown, a lubricating oil tank is provided according to a first aspect of the present application, comprising: a tank body 110, wherein an accommodating space is formed within the tank body 110; a liquid level sensor 120 disposed within the tank body 110 for detecting the liquid level height within the tank body 110; a heating assembly 130 connected to the tank body 110, wherein at least a portion of the heating assembly 130 is located within the accommodating space; and a temperature sensor 140 disposed on the heating assembly 130.

[0052] The oil tank for lubricating oil provided by the embodiment of the present application comprises a tank body 110, a liquid level sensor 120, a heating assembly 130 and a temperature sensor 140. During use, the accommodating space in the oil tank can be used to store and accommodate lubricating oil. The liquid level sensor 120 can be used to detect the liquid level of the lubricating oil in the oil tank. The temperature sensor 140 arranged above the heating assembly 130 can be used to detect the current temperature of the lubricating oil. The heating assembly 130 can be controlled to start and stop based on the liquid level and the temperature of the lubricating oil, so as to realize automatic control of the start and stop of the heating assembly 130. The heating assembly 130 can be controlled to start, so as to heat the lubricating oil stored in the tank body 110. The temperature of the lubricating oil can be maintained above a certain temperature, so as to avoid solidification or reduction of flowability of the lubricating oil, and to ensure good supply capacity and lubricating capacity of the lubricating oil.

[0053] The oil tank for lubricating oil provided by the embodiment of the present application considers that in the prior art, some oil tanks are provided with a temperature sensor 140. The temperature sensor 140 in the prior oil tank is directly arranged in the tank body 110, so that the arrangement positions of the temperature sensors 140 in oil tanks of different models or different batches of the same model are different, so that the temperature measurement points of the temperature sensors 140 are different, so that the oil tank temperature measurement does not have consistency and uniformity. In addition, it is inconvenient to install the temperature sensor 140, and it is inconvenient to maintain the oil tank and replace the temperature sensor 140. Therefore, the oil tank for lubricating oil provided by the embodiment of the present application arranges the temperature sensor 140 above the heating assembly 130. On the one hand, the arrangement positions of the temperature sensors 140 in different oil tanks or different batches of the same model are the same, so that the temperature measurement points of the temperature sensors 140 are the same, so that the oil tank temperature measurement has consistency and uniformity. On the other hand, the temperature sensor 140 can be modularized with the heating assembly 130, so as to facilitate installation of the temperature sensor 140. In addition, it is not necessary to form a component for installing the temperature sensor 140 on the tank body 110, so as to facilitate disassembly and assembly of the temperature sensor 140 and maintenance of the oil tank for lubricating oil.

[0054] In a feasible implementation, the heating assembly 130 comprises a shell 131 connected to the outer wall of the tank body 110 and a thermocouple 132 connected to the shell 131 and located in the accommodating space. The temperature sensor 140 is connected to the shell 131, and part of the temperature sensor 140 is arranged in the accommodating space.

[0055] In the technical scheme, the structure of the heating assembly 130 is further provided, the heating assembly 130 comprises a shell 131 and a thermocouple 132, the shell 131 is connected to the outer wall of the tank body 110, so that the fixing of the heating assembly 130 is more reliable, and the thermocouple 132 is connected to the shell 131 and inserted into the containing space, so that the thermocouple 132 can provide heat energy for the lubricating oil stored in the tank body 110 under the condition of being powered on; the temperature sensor 140 is connected to the shell 131, and part of the temperature sensor 140 is arranged in the containing space, so that the fixing of the temperature sensor 140 is more reliable.

[0056] In an embodiment, the heating assembly 130 further comprises a control circuit 133 connected to the heating assembly 130 for powering on the heating assembly 130, the control circuit 133 is arranged in the shell 131 and connected to the liquid level sensor 120 and the temperature sensor 140.

[0057] In the technical scheme, the heating assembly 130 can further comprise a control circuit 133 connected to the heating assembly 130 for powering on the heating assembly 130, the control circuit 133 is arranged in the shell 131, so that the shell 131 can protect the control circuit 133, and the control circuit 133 is connected to the liquid level sensor 120 and the temperature sensor 140, so that the control circuit 133 can control the powering on or off of the thermocouple 132 based on the detection results of the liquid level sensor 120 and / or the temperature sensor 140, and the automatic opening of the heating assembly 130 can be realized.

[0058] It can be understood that, as shown in Figure 1 The thermocouple 132 needs to be arranged separately from the temperature sensor 140 to avoid the influence of the temperature of the thermocouple 132 on the temperature sensor 140.

[0059] In an embodiment, the lubricating oil tank further comprises an oil outlet supply assembly 150, part of the oil outlet supply assembly 150 is arranged in the containing space; and a return oil assembly 160, part of the return oil assembly 160 is arranged in the containing space.

[0060] In the technical scheme, the lubricating oil tank can further comprise an oil outlet supply assembly 150 and a return oil assembly 160, the oil outlet supply assembly 150 can comprise an oil pipe and an oil pump, one end of the oil pipe is arranged at the bottom of the tank body 110, and is used for pumping the lubricating oil stored in the tank body 110 out of the tank body 110; and the return oil assembly 160 can also comprise an oil pipe and an oil pump, one end of the oil pipe is arranged at the bottom of the tank body 110, and is used for pumping the lubricating oil outside the tank body 110 back into the tank body 110.

[0061] In some examples, a manhole 170 for user observation and a maintenance hole 180 for maintenance can also be formed on the box 110.

[0062] As shown in the drawings, Figure 2 According to the second aspect of the embodiments of the present application, a control method of an oil tank for lubricating oil is provided, which is applied to the oil tank for lubricating oil in any of the technical solutions, and the control method comprises:

[0063] Step 201: In response to the constant temperature oil supply instruction, the liquid level sensor is used to collect the liquid level information in the tank. In this technical solution, the constant temperature oil supply instruction can be automatically generated by the oil tank for lubricating oil, such as collecting the ambient temperature of the oil tank for lubricating oil, and if the ambient temperature is lower than a certain threshold, the constant temperature oil supply instruction can be automatically generated, or the constant temperature oil supply instruction can be input by the user based on the actual demand. After receiving the constant temperature oil supply instruction, the liquid level sensor is used to collect the liquid level information in the tank.

[0064] Step 202: Based on the liquid level information, the start and stop of the heating assembly are controlled. It can be understood that if the liquid level is too low, the heating assembly does not need to be started in this case, so the heating assembly can be started when the liquid level is greater than a preset value. It can be understood that the height of the preset value is related to the installation height of the heating assembly and the volume of the tank, and the value of the preset value needs to be greater than the installation height of the heating assembly.

[0065] Through the control method of the oil tank for lubricating oil provided by the embodiments of the present application, the liquid level of the lubricating oil in the oil tank can be detected through the setting of the liquid level sensor, and the start and stop of the heating assembly are controlled based on the liquid level of the lubricating oil. In this way, the start and stop of the heating assembly can be automatically controlled, the lubricating oil stored in the tank can be heated by controlling the start of the heating assembly, the temperature of the lubricating oil can be maintained above a certain temperature, and the lubricating oil can be prevented from solidifying or reducing the flowability, so that the lubricating oil can have good supply capacity and lubricating capacity.

[0066] In a feasible implementation, the step of controlling the start and stop of the heating assembly based on the liquid level information comprises:

[0067] Step 2021: When the liquid level information is greater than a first threshold, the heating assembly is started, and the current liquid level information is recorded as first liquid level information;

[0068] Step 2022: After the heating assembly is started for a time longer than a first time, the liquid level information is collected again and recorded as second liquid level information;

[0069] Step 2023: The first liquid level information and the second liquid level information are compared, and the start and stop of the heating assembly are determined based on the comparison result.

[0070] In the technical solution, further provided are specific steps of controlling the start and stop of the heating assembly based on the liquid level information. In the case of receiving the constant-temperature oil supply instruction, the heating assembly is controlled to start in the case of the liquid level information being greater than the first threshold value. After the first time length, second liquid level information is acquired based on the liquid level sensor. Finally, the start and stop of the heating assembly are determined based on the comparison result of the first liquid level information and the second liquid level information. Based on this, the start and stop of the heating assembly can be determined based on the liquid level information only. It can be understood that the control method provided by the embodiments of the present application considers that the lubricating oil will expand under heating, and the heating assembly is started at the same power in combination with thermal expansion and contraction. If the current temperature of the lubricating oil is higher, the heating efficiency of the lubricating oil is lower, and the volume change of the lubricating oil will be reduced. Therefore, if the first liquid level information and the second liquid level information are close, it indicates that the current temperature of the lubricating oil is higher. In this case, the heating assembly can be controlled to stop. On the contrary, if the first liquid level information and the second liquid level information are quite different, it indicates that the current temperature of the lubricating oil is lower. In this case, the heating assembly can be controlled to start.

[0071] It can be understood that the second liquid level information is used as the first liquid level information, and steps 2022 to 2023 are repeatedly executed, so that closed-loop control of the lubricating oil tank can be realized. Based on this, the start and stop of the heating assembly can be determined based on the liquid level information only, so that the control method is more simple and efficient.

[0072] It can be understood that the first time length can be determined based on the environmental temperature and the specific heat capacity of the lubricating oil. The first time length is negatively correlated with the environmental temperature and positively correlated with the specific heat capacity of the lubricating oil.

[0073] In a feasible implementation, the step of determining the start and stop of the heating assembly based on the comparison result includes: in the case of the comparison result being greater than the second threshold value, the heating assembly is controlled to maintain in the start state; and in the case of the comparison result being less than or equal to the second threshold value, the heating assembly is controlled to stop.

[0074] In the technical solution, further provided are specific steps of determining the start and stop of the heating assembly based on the comparison result. In the case of the comparison result being greater than the second threshold value, it indicates that the current temperature of the lubricating oil is lower. In this case, the heating assembly can be controlled to start. In the case of the comparison result being less than or equal to the second threshold value, it indicates that the current temperature of the lubricating oil is higher. In this case, the heating assembly can be controlled to stop, so that the start and stop of the heating assembly are more secure.

[0075] In a feasible implementation, the step of controlling the start and stop of the heating assembly based on the liquid level information further includes: acquiring temperature information based on a temperature sensor; and in the case of the temperature information being greater than a third threshold value, the heating assembly is controlled to stop.

[0076] In the technical solution, the temperature information can also be collected when determining the start-stop condition of the heating assembly. When the temperature information is greater than the third threshold value, it indicates that the oil temperature has reached the expected requirement, and in this case, the heating assembly can be controlled to be turned off.
