Description
Technical Field
[0001] This utility model relates to the field of hydraulic device technology, specifically to an intelligent hydraulic device. Background Technology
[0002] Intelligent hydraulic devices are energy conversion devices that utilize liquids (usually oil or water-based fluids) to transmit pressure within a closed system. Their core principle is based on Pascal's Law. They convert mechanical energy into hydraulic energy by compressing the liquid, which then drives actuators to perform mechanical actions such as pushing, pulling, and rotating. These devices are characterized by high output force, smooth speed regulation, and flexible layout, and are widely used in engineering machinery, industrial production lines, aerospace, and automotive braking systems, especially suitable for scenarios requiring high power density and precise control.
[0003] Traditional intelligent hydraulic devices do not have the function of automatically cooling hydraulic oil. If the hydraulic oil in the tank is immediately drawn out and used after being returned, the heat of the hydraulic oil cannot be dissipated in time. The excessively high oil temperature will reduce the control accuracy of the hydraulic system and affect the service life of hydraulic components. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] like Figures 1-4 As shown, this utility model provides a technical solution: an intelligent hydraulic device, comprising:
[0024] Hydraulic oil tank 1;
[0025] Diverting output mechanism 2 is located on the top of hydraulic oil tank 1. Diverting output mechanism 2 is used to automatically cool and divert hydraulic oil. Diverting output mechanism 2 includes a cooling component and a diverting component.
[0026] Hydraulic oil return mechanism 3 is located on the top of hydraulic oil tank 1 and is used to filter the returned hydraulic oil.
[0027] The cooling assembly includes a square tube 21 and a hydraulic pump 23. Both the square tube 21 and the hydraulic pump 23 are fixedly installed on the top of the hydraulic oil tank 1. The input end of the hydraulic pump 23 extends into the inner cavity of the hydraulic oil tank 1. The square tube 21 is fixedly connected to the output end of the hydraulic pump 23. A heat exchange tube 211 is fixedly connected between the front and back sides of the inner wall of the square tube 21. Through holes 212 are opened on both the front and back sides of the square tube 21. A connecting cover 213 is fixedly connected to the front side of the square tube 21, and a fan 214 is fixedly connected to the front side of the connecting cover 213. A digital thermometer 215 is fixedly installed on the front side of the square tube 21, and the measuring end of the digital thermometer 215 extends into the inner cavity of the square tube 21. When the hydraulic pump 23 is working, it can draw... Hydraulic oil is drawn from inside the hydraulic oil tank 1 and then output through the inner cavity of the square tube 21. At this time, the temperature of the hydraulic oil output by the hydraulic pump 23 is monitored by the digital thermometer 215, and the monitored data is fed back to the controller 12. If the temperature exceeds the preset value, it means that the oil temperature is too high and will affect the performance. The controller 12 will then control the fan 214 to work, absorb the cold air from the outside, and make the cold air flow through the inner cavity of the heat exchange tube 211. The cold air will exchange heat with the hydraulic oil, reduce the temperature of the hydraulic oil, and ensure the performance of the hydraulic oil. Through the design of the through hole 212 and the connecting cover 213, the inner cavity of the fan 214 is connected to the inner cavity of the heat exchange tube 211.
[0028] As one implementation method in this embodiment, such as Figure 3 As shown, the flow divider assembly includes a flow divider pipe 22, which is fixedly installed on the top of the hydraulic oil tank 1. The flow divider pipe 22 is fixedly connected to the right side of the square tube 21. A solenoid valve 221 is fixedly connected to the right side of the flow divider pipe 22. The number of solenoid valves 221 is set to five. A check valve 222 is fixedly connected to the right side of each of the five solenoid valves 221. In use, the oil inlet end of the actuator is connected to the connecting pipe 224. When the hydraulic pump 23 is running, it controls the corresponding solenoid valve 221 to open, so that hydraulic oil can be unidirectionally delivered to the corresponding actuator through the check valve 222, so that the actuator can work.
[0029] As one implementation method in this embodiment, such as Figure 3 As shown, a receiving pipe 223 is fixedly connected to the right side of the one-way valve 222, and a connecting pipe 224 is fixedly connected to the right side of the receiving pipe 223. A digital pressure gauge 225 is fixedly connected to the top of the receiving pipe 223. Through the design of the digital pressure gauge 225, the pressure of the hydraulic oil delivered to the actuator can be monitored, and the monitored data can be fed back to the controller 12. When the preset value is reached, the controller 12 will control the hydraulic pump 23 to stop working to avoid the problem that excessive pressure may easily damage the actuator.
[0030] As one implementation method in this embodiment, such as Figure 4As shown, the hydraulic oil return mechanism 3 includes a return frame 31, which is fixedly connected to the top of the hydraulic oil tank 1. A cover plate 32 is movably inserted into the top of the return frame 31, and a return pipe port is fixedly connected to the top of the cover plate 32. The oil outlet of the actuator is connected to the return pipe port. When the actuator unloads oil, the hydraulic oil will pass through the cover plate 32 and the return frame 31 and return to the inner cavity of the hydraulic oil tank 1, which facilitates the circulation of hydraulic oil.
[0031] As one implementation method in this embodiment, such as Figure 4 As shown, a connecting box 33 located in the inner cavity of the return frame 31 is fixedly connected to the bottom of the cover plate 32. A hydraulic oil filter 34 is threadedly connected to the bottom of the connecting box 33. During the hydraulic oil return process, it will first enter the inner cavity of the connecting box 33 and then enter the interior of the hydraulic oil filter 34. Through the design of the hydraulic oil filter 34, the hydraulic oil can be filtered to improve the quality of the hydraulic oil. If the hydraulic oil filter 34 needs to be replaced, the cover plate 32 is pulled out from the top of the return frame 31, and the hydraulic oil filter 34 can be rotated off from the bottom of the connecting box 33 for replacement.
[0032] As one implementation method in this embodiment, such as Figure 1 As shown, a transparent level bar 11 is fixedly installed on the front of the hydraulic oil tank 1, and a controller 12 is fixedly installed on the top of the hydraulic oil tank 1. A movable cover 13 is threadedly connected to the top of the hydraulic oil tank 1. The transparent level bar 11 facilitates the user's observation of the hydraulic oil level inside the hydraulic oil tank 1. When replenishing the hydraulic oil, the movable cover 13 can be removed from the top of the hydraulic oil tank 1. The digital thermometer 215, fan 214, digital pressure gauge 225, solenoid valve 221, and hydraulic pump 23 are all electrically connected to the controller 12. The controller 12 in this solution is a device that can be purchased on the market by those skilled in the art. The device has not been structurally modified in this paper. Therefore, those skilled in the art are familiar with its working principle based on their professional knowledge and can use it skillfully.
[0033] Working principle: During use, the oil inlet of the actuator is connected to the connecting pipe 224, and the oil outlet of the actuator is connected to the return pipe. The hydraulic pump 23 is controlled to run, and the corresponding solenoid valve 221 is controlled to open. Hydraulic oil can be delivered unidirectionally to the corresponding actuator through the check valve 222 to facilitate the operation of the actuator. At this time, the temperature of the hydraulic oil output by the hydraulic pump 23 is monitored by the digital thermometer 215, and the monitored data is fed back to the controller 12. If the temperature exceeds the preset value, it means that the oil temperature is too high and will affect the performance. The controller 12 will then control the fan 214 to work, absorb the cold air from the outside, and make the cold air flow through the inner cavity of the heat exchange tube 211. The cold air will exchange heat with the hydraulic oil, reducing the temperature of the hydraulic oil. When the actuator unloads oil, the hydraulic oil will flow back to the inner cavity of the hydraulic oil tank 1 through the cover plate 32 and the return frame 31, which facilitates the circulation of hydraulic oil.
