[0015] Preferably, an oil level sensor is installed at the bottom of the oil tank body for accurately measuring the oil liquid inventory.

[0016] Preferably, heat dissipation fin plates are installed at the top of the oil tank body.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, with the cooperation of the positioning phase change temperature control component, once the infrared temperature zone sensor detects that the temperature difference in a local area exceeds the set threshold (such as a difference of ±3°C from the average oil temperature), the fuzzy controller determines that there is an abnormal oil temperature in this area, and then triggers a series of adjustment actions. The angle rotation structure starts, drives the T-shaped fixing frame to rotate, and further causes the circumferential trajectory driving structure to act. Driven by the azimuth angle servo motor, it drives the plate body and the electromagnetic guide rod to move along the circumferential trajectory. The angle laser ruler measures the rotation angle in real time and provides feedback to the fuzzy controller. At this time, the front-end azimuth adjustment structure drives the phase change material contact part and the oil temperature sensor to move to the area with abnormal oil temperature. The phase change material contact part is in close contact with the paraffin phase change material layer to strengthen heat exchange. The oil temperature sensor feeds back the oil temperature data in this area to the fuzzy controller to detect the local temperature difference in real time. Cooperating with the front-end azimuth adjustment structure to drive the phase change material contact part and the oil temperature sensor to accurately locate to the abnormal area, realizing targeted monitoring and control of the area with abnormal oil temperature, quickly discovering and solving the problem of too high or too low local oil temperature, avoiding the influence of local oil temperature abnormality on the performance of the entire hydraulic system. At the same time, by adjusting the contact state between the phase change material contact part and the paraffin phase change material layer through the front-end azimuth adjustment structure, intelligent collaborative control is realized, effectively reducing the startup times of the cooler and the heater, reducing energy consumption, and improving the adaptability of the oil temperature adjustment system to complex working conditions. Under different loads, different ambient temperatures and other conditions, it can ensure that the oil temperature of the hydraulic oil tank is stable in a suitable range, enhancing the reliability and durability of the hydraulic system.

[0019] 2. In the present invention, with the cooperation of the microchannel regulation component, when the oil temperature is too high, the microchannel cooler starts. Its microchannel structure increases the heat exchange area, and the flowing cooling medium takes away heat. The ultrasonic atomizer transports atomized coolant to improve the heat exchange efficiency. The vibration generator on the bottom wall of the counterflush heat dissipation cavity promotes air convection to enhance heat dissipation. The thermoelectric generator uses the temperature difference to generate electricity to realize energy recovery. If the oil temperature is too low, the heater starts, and at the same time, the flow rate of the cooling medium in the microchannel cooler is reduced. The fuzzy controller will continuously and dynamically adjust according to the change of the oil temperature. For example, when the temperature in the area with abnormal oil temperature continues to rise, operations such as increasing the flow rate of the cooling medium in the microchannel cooler are carried out. When the load of the hydraulic system changes, the heat dissipation power of the microchannel regulation component is also adjusted accordingly. At the same time, the positioning sliding block is controlled to drive the positioning phase change temperature control component to move to the area where the oil temperature changes rapidly, so that the overall device significantly improves the oil temperature regulation efficiency and accuracy.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Example 1: Refer to Figure 1 - Figure 6As shown: A hydraulic oil tank integrated with an oil temperature regulation function, including an oil tank body 1, a rectangular guide rail 5 is installed inside the oil tank body 1, a paraffin phase change material layer is installed on the inner wall surface of the oil tank body 1, a high-precision temperature sensor 4 is installed on the inner wall of the oil tank body 1, a positioning slider 9 is slidably connected to the side end of the rectangular guide rail 5, a positioning phase change temperature control component 8 is connected to the side end of the positioning slider 9, and a microchannel regulation component 7 is installed inside the oil tank body 1;

[0029] The positioning phase change temperature control component 8 includes an infrared temperature zone sensor 85, a front-end orientation adjustment structure 891, and a phase change material contact member 892. The infrared temperature zone sensor 85 is installed on the side close to the positioning phase change temperature control component 7 for real-time detection of temperature differences. The phase change material contact member 892 is installed on the side end of the front-end orientation adjustment component 891, and an oil temperature sensor 893 is installed at the top of the phase change material contact member 892 for real-time collection of oil temperature data.

[0030] The positioning phase change temperature control component 8 further includes an angle rotation structure 81. The angle rotation structure 81 is installed on the side wall of the positioning slider 9, and the top output end of the angle rotation structure 81 is connected to a T-shaped fixing frame 82. The left and right ends of the T-shaped fixing frame 82 are symmetrically rotatably connected to a circular trajectory driving structure 86.

[0031] A plate body 83 is installed on the side end of the circular trajectory driving structure 86, an electromagnetic guide rod 84 is fixedly connected to the surface of the plate body 83, and an azimuth angle servo motor 87 is rotatably connected to the side end of the circular trajectory driving structure 86.

[0032] An angle laser ruler 88 is rotatably connected to the side end of the azimuth angle servo motor 87, a pneumatic shaft joint arm 89 is rotatably connected to the bottom end inside the azimuth angle servo motor 87, and a front-end positioning calibration frame 890 is installed on the side end of the pneumatic shaft joint arm 89.

[0033] The front-end orientation adjustment structure 891 is installed on the side end of the front-end positioning calibration frame 890. The front-end orientation adjustment structure 891 is used to drive the phase change material contact member 892 and the oil temperature sensor 893 to adjust positions, strengthening the temperature monitoring and regulation of abnormal oil temperature areas.

[0034] In this embodiment, first, when the hydraulic system is started, the high-precision temperature sensor 4 and the infrared temperature zone sensor 85 start to work. The high-precision temperature sensor 4 monitors the overall oil temperature inside the oil tank body 1 in real time, while the infrared temperature zone sensor 85 focuses on detecting and positioning the temperature difference in the area near the phase change temperature control component 8. As the hydraulic system operates, the high-precision temperature sensor 4 continuously collects the oil temperature data inside the oil tank body 1 and transmits it to the fuzzy controller 72. If the oil temperature is within the normal operating range (e.g., 40 - 50 °C), the fuzzy controller 72 maintains the current state, and the microchannel regulation component 7 and the phase change temperature control component 8 remain relatively stationary, only performing routine temperature monitoring. When the infrared temperature zone sensor 85 detects that the temperature difference in a local area exceeds the set threshold (e.g., the temperature in a certain area differs from the average oil temperature by ±3 °C), the fuzzy controller 72 determines that there may be an abnormal oil temperature in this area. At this time, the angle rotation structure 81 starts to work. The angle rotation structure 81 is installed on the side wall of the positioning slider 9, and its top output end drives the T-shaped fixing frame 82 to rotate. The circumferential trajectory driving structure 86 at both the left and right ends of the T-shaped fixing frame 82 then moves accordingly. The circumferential trajectory driving structure 86 is driven by the azimuth angle servo motor 87. The azimuth angle servo motor 87 adjusts the rotation angle of the output shaft according to the instruction of the fuzzy controller 72, driving the plate body 83 and the electromagnetic guide rod 84 installed thereon to move along the circumferential trajectory. At the same time, the angle laser ruler 88 measures the rotation angle of the azimuth angle servo motor 87 in real time, providing accurate angle data feedback to the fuzzy controller 72 to ensure the accuracy of the circumferential trajectory movement. When an abnormal oil temperature area is detected, the front-end azimuth adjustment structure 891 starts to work under the support of the front-end positioning calibration frame 890. The front-end azimuth adjustment structure 891 drives the phase change material contact part 892 and the oil temperature sensor 893 to move, so that the phase change material contact part 892 moves near the abnormal oil temperature area, making the contact with the paraffin phase change material layer closer and strengthening the heat exchange between the two. The oil temperature sensor 893 then collects the oil temperature data in this area in real time and feeds the data back to the fuzzy controller 72, so that the fuzzy controller 72 can more accurately grasp the oil temperature change in the abnormal area. At the same time, the microchannel regulation component 7 also participates in the work when the oil temperature is abnormal. The microchannel structure inside the microchannel regulation component 7 has high efficient heat exchange capacity. When the fuzzy controller 72 determines that the oil temperature is too high, it adjusts the flow rate and velocity of the microchannel cooler 77 to accelerate the removal of the heat inside the oil tank body 1, realizing a rapid decrease in the oil temperature. If the oil temperature is too low, the microchannel regulation component 7 can be switched to the heating mode (e.g., heating the cooling medium through the heater 74 and then recycling it) to increase the oil temperature. If the temperature in the abnormal oil temperature area continues to rise, the fuzzy controller 72 will increase the flow rate of the cooling medium in the microchannel regulation component 7 and further adjust the front-end azimuth adjustment component 891 to make the phase change material contact part 892 contact the paraffin phase change material layer more deeply, enhancing the heat exchange effect. When the load of the hydraulic system changes, such as when the load increases and the overall upward trend of the oil temperature accelerates,The fuzzy controller 72 automatically increases the heat dissipation power of the microchannel regulation component 7, and at the same time controls the positioning slider 9 to slide on the rectangular guide rail 5, driving the positioning phase change temperature control component 8 to move to the area where the oil temperature rises faster, and conducts temperature monitoring and regulation in advance to adapt to the oil temperature changes under different working conditions. The overall device detects the local temperature difference in real time through the infrared temperature zone sensor 85, and cooperates with the front-end azimuth adjustment structure 891 to drive the phase change material contact 892 and the oil temperature sensor 893 to accurately locate to the abnormal area, realizing targeted monitoring and regulation of the abnormal oil temperature area, being able to quickly detect and solve the problems of too high or too low local oil temperature, avoiding the influence of local oil temperature abnormality on the performance of the entire hydraulic system. At the same time, the contact state between the phase change material contact 892 and the paraffin phase change material layer is adjusted through the front-end azimuth adjustment structure 891, realizing intelligent collaborative regulation, effectively reducing the start-up times of the cooler and the heater 74, reducing energy consumption, and improving the adaptability of the oil temperature regulation system to complex working conditions. Under different loads, different ambient temperatures and other conditions, it can ensure that the oil temperature of the hydraulic oil tank is stable in a suitable range, enhancing the reliability and durability of the hydraulic system.,

[0035] Embodiment 2: According to Figure 2 、 Figure 3 and Figure 6 shown, the microchannel regulation component 7 includes a fuzzy controller 72 and a microchannel cooler 77. The fuzzy controller 72 is installed on the right side of the inner wall of the oil tank body 1. A buffer joint frame 71 is fixedly connected to the inner wall of the oil tank body 1. The microchannel cooler 77 is installed at the bottom of the frame body of the buffer joint frame 71.

[0036] A thermoelectric generator 790 is installed at the output end of the microchannel cooler 77. A hydraulic drive output structure 73 is installed inside the frame body of the buffer joint frame 71. A heater 74 is installed at the front end of the hydraulic drive output structure 73. The microchannel cooler 77 is installed at the bottom end of the hydraulic drive output structure 73 for greatly increasing the heat exchange area. A counterflush heat dissipation cavity 78 is installed at the bottom end of the microchannel cooler 77. Vibration generators 79 are installed on the bottom wall surfaces of the counterflush heat dissipation cavity 78.

[0037] An ultrasonic atomizer 75 is installed on the surface of the frame body of the buffer joint frame 71. The top of the ultrasonic atomizer 75 is connected to a connection end 76. The top of the connection end 76 is connected to the internal pipeline of the microchannel cooler 77 through a flexible pipeline.

[0038] In this embodiment, when the paraffin phase change material layer on the inner wall of the above oil tank body 1 is ready to play the role of energy storage and energy release when the oil temperature changes, at this time, the fuzzy controller 72 in the microchannel regulation component 7 is also initialized to receive the initial oil temperature data transmitted from the high-precision temperature sensor 4, etc. As the hydraulic system operates, the high-precision temperature sensor 4 continuously collects the oil temperature data in the oil tank body 1 and transmits it to the fuzzy controller 72. If the oil temperature is within the normal working range (such as 40 - 50 °C), the fuzzy controller 72 maintains the current state, and the microchannel cooler 77, heater 74, etc. in the microchannel regulation component 7 remain relatively stationary, only performing conventional temperature monitoring. The fuzzy controller 72 continuously analyzes the oil temperature data to judge the trend of oil temperature change. When the infrared temperature zone sensor 85 detects that the temperature difference in a local area exceeds the set threshold (such as the temperature in a certain area differs from the average oil temperature by ±3 °C), the fuzzy controller 72 determines that there may be an abnormal oil temperature in this area. At this time, the above positioning phase change temperature control component 8 operates, and at the same time, the microchannel regulation component 7 starts to intervene, enabling the fuzzy controller 72 to quickly judge the abnormal oil temperature situation, such as too high or too low oil temperature, based on the data fed back by the high-precision temperature sensor 4 and the infrared temperature zone sensor 85, combined with the trend of oil temperature change. If the fuzzy controller 72 determines that the oil temperature is too high, it immediately starts the microchannel cooler 77. The microchannel cooler 77 is installed at the bottom end of the hydraulic drive output structure 73, and its microchannel structure greatly increases the heat exchange area. The cooling medium (such as water or coolant) flows in the microchannels, quickly taking away the heat of the hydraulic oil. At the same time, the ultrasonic atomizer 75 starts to work, and through the connection end 76 and the flexible pipeline, it conveys the atomized coolant into the internal pipeline of the microchannel cooler 77. The atomized coolant further improves the heat exchange efficiency and accelerates the reduction of the oil temperature. The vibration generator 79 at the bottom wall of the counterflush heat dissipation cavity 78 starts to generate vibration to promote air convection and enhance the heat dissipation effect. The thermoelectric generator 790 starts to work, converting the temperature difference at the output end of the microchannel cooler 77 into electrical energy to supply power to other low-power components of the system, realizing energy recovery and utilization. When the fuzzy controller 72 determines that the oil temperature is too low, it controls the heater 74 to start heating the hydraulic oil. At the same time, it reduces the flow rate of the cooling medium in the microchannel cooler 77 to cooperate with the heater 74 to raise the oil temperature. If the temperature in the abnormal oil temperature area continues to rise, the fuzzy controller 72 increases the flow rate of the cooling medium in the microchannel cooler 77, increases the atomization amount of the ultrasonic atomizer 75, enhances the vibration intensity of the vibration generator 79, and at the same time further adjusts the front-end azimuth adjustment component 891 to make the phase change material contact member 892 contact the paraffin phase change material layer more deeply to strengthen the heat exchange. If the temperature in the too low oil temperature area continues to drop, the fuzzy controller 72 increases the power of the heater 74 and reduces the flow rate of the cooling medium to accurately adjust the oil temperature, significantly improving the oil temperature regulation efficiency and accuracy overall.

[0039] Embodiment 3: According to Figure 1 and Figure 2As shown, an oil level sensor 6 is installed at the bottom of the oil tank body 1 for accurately measuring the oil fluid inventory.

[0040] An oil inlet / outlet 2 is installed at the side end of the oil tank body 1, and brake wheels are provided at the four ends of the bottom of the oil tank body 1.

[0041] Radiating fins 3 are installed at the top of the oil tank body 1.

[0042] In this embodiment, based on the data fed back by the high-precision temperature sensor 4 and the infrared temperature zone sensor 85, the above-mentioned fuzzy controller 72 combines the trend of oil temperature change to quickly judge abnormal oil temperature conditions, such as too high or too low oil temperature. During this period, the oil level sensor 6 continuously monitors the oil level. If the oil level shows an abnormal drop, it may mean that there is a leak in the overall device system. The fuzzy controller 72 issues an alarm to prompt the maintenance personnel to check. When the oil temperature is stable, the radiating fins 3 still continuously perform natural heat dissipation to maintain the temperature balance inside the oil tank body 1. If the oil level sensor 6 detects a drop in the oil level, the fuzzy controller 72 dynamically adjusts the operating parameters of the hydraulic system, such as reducing the output power of the oil pump, to reduce oil fluid consumption and prevent system failures caused by insufficient oil fluid.

[0043] The wiring diagrams of the high-precision temperature sensor 4, the oil level sensor 6, the fuzzy controller 72, the ultrasonic atomizer 75, the microchannel cooler 77, the vibration generator 79, the infrared temperature zone sensor 85, the azimuth angle servo motor 87, the angle laser ruler 88, and the oil temperature sensor 893 in the present invention belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements are not explained in detail.

[0044] The usage method and working principle of this device: First, when the hydraulic system is started, the high-precision temperature sensor 4 and the infrared temperature zone sensor 85 start to work immediately. The high-precision temperature sensor 4 is responsible for real-time monitoring of the overall oil temperature inside the oil tank body 1, and the infrared temperature zone sensor 85 focuses on detecting the temperature difference in the area near the phase change temperature control component 8. When the oil temperature is within the normal working range (40 - 50 °C), the microchannel regulation component 7 and the phase change temperature control component 8 remain relatively stationary and only perform conventional temperature monitoring.

[0045] Once the infrared temperature zone sensor 85 detects that the local area temperature difference exceeds the set threshold (such as ±3°C different from the average oil temperature), the fuzzy controller 72 determines that there is an abnormal oil temperature in this area, and then triggers a series of adjustment actions. The angle rotation structure 81 starts, driving the T-shaped fixing frame 82 to rotate, and further causing the circumferential trajectory driving structure 86 to act. Driven by the azimuth angle servo motor 87, it drives the plate body 83 and the electromagnetic guide rod 84 to move along the circumferential trajectory. The angle laser ruler 88 measures the rotation angle in real time and provides feedback to the fuzzy controller 72. At this time, the front-end azimuth adjustment structure 891 drives the phase change material contact member 892 and the oil temperature sensor 893 to move to the area with abnormal oil temperature. The phase change material contact member 892 is in close contact with the paraffin phase change material layer to strengthen heat exchange, and the oil temperature sensor 893 feeds back the oil temperature data of this area to the fuzzy controller 72.

[0046] The micro-channel regulation component 7 participates in the work when the oil temperature is abnormal. When the oil temperature is too high, the micro-channel cooler 77 starts. Its micro-channel structure increases the heat exchange area, and the flowing cooling medium takes away heat. The ultrasonic atomizer 75 transports atomized coolant to improve the heat exchange efficiency. The vibration generator 79 at the bottom of the counter-flow heat dissipation cavity 78 promotes air convection to enhance heat dissipation. The thermoelectric generator 790 uses the temperature difference to generate electricity for energy recovery. If the oil temperature is too low, the heater 74 starts, and at the same time reduces the flow rate of the cooling medium in the micro-channel cooler 77. The fuzzy controller 72 will continuously and dynamically adjust according to the change of the oil temperature. For example, when the temperature of the area with abnormal oil temperature continues to rise, operations such as increasing the flow rate of the cooling medium in the micro-channel cooler 77 are carried out. When the load of the hydraulic system changes, the heat dissipation power of the micro-channel regulation component 7 is also adjusted accordingly. At the same time, the positioning sliding block 9 is controlled to drive the positioning phase change temperature control component 8 to move to the area where the oil temperature changes rapidly.

[0047] The oil level sensor 6 at the bottom of the oil tank body 1 monitors the oil liquid inventory in real time. If the oil level drops abnormally, the fuzzy controller 72 issues an alarm to prompt the maintenance personnel to check. At the same time, the operating parameters of the hydraulic system are dynamically adjusted according to the oil level drop situation. The heat dissipation fins 3 on the top of the oil tank body 1 continuously dissipate heat naturally when the oil temperature is stable to maintain the temperature balance in the tank. Through precise temperature monitoring, intelligent collaborative regulation, and effective management of the oil level, this device can quickly respond to local abnormal oil temperature, reduce the startup times of the cooler and the heater 74, reduce energy consumption, and enhance the reliability and durability of the hydraulic system under complex working conditions.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
