DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0026] Example:

[0027] See also Figure 1 , an adaptive pressure regulating hydraulic station, comprising an oil tank 1 and a variable pump 3 and a diverter valve 4 installed at both ends of the surface of the oil tank 1.

[0028] The oil tank 1 is used to store hydraulic oil, and a filter device is provided inside to filter impurities and particles in the hydraulic oil to ensure the cleanliness of the hydraulic oil and extend the service life of the hydraulic components. An oil level gauge or oil level sensor is installed on the oil tank 1 to monitor the oil level in real time. When the oil level is too low, an alarm signal is issued to remind the operator to replenish the hydraulic oil in time.

[0029] Among them, the variable pump 3 is the heart of the device, which can automatically adjust the flow and pressure according to the needs of the system, and has its own safety measures such as overload protection and overheating protection to ensure that the variable pump 3 can automatically shut down or reduce power under abnormal circumstances to prevent equipment damage and accidents.

[0030] The diverter valve 4 has a multi-way diverting function, which can divert the hydraulic oil to multiple different hydraulic actuators to achieve complex multi-way control requirements. A flow regulating valve is set on the diverter valve 4 to adjust the flow size of each branch separately to meet the different flow requirements of different actuators.

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 An adaptive pressure regulating hydraulic station includes a pressure regulating device 2 installed on the surface of an oil tank 1, the pressure regulating device 2 is composed of a pipeline mechanism 21, a pressure detection mechanism 22, a control mechanism 23 and a connecting mechanism 24, the pipeline mechanism 21 includes a pipeline I 211, a pipeline II 212 and a plurality of branch pipes 213; the pressure detection mechanism 22 includes a connecting tube 221, two threaded holes 222, a pressure sensor 223, a pressure display gauge 224 and an assembly 225; the assembly 225 includes two hollow threaded heads 2251 and two sets of flanges 2252; the control mechanism 23 includes a housing 231, a processor 232 and a display screen 233; the connecting mechanism 24 includes a plurality of retaining rings 241 and a plurality of locking nuts 242.

[0032] Among them, the design of the pipeline mechanism 21 facilitates the flow of hydraulic oil. Through the design of pipeline I 211 and pipeline II 212, the flow path of the hydraulic oil is clearer. At the same time, the equally spaced arrangement of the branch pipes 213 makes the distribution of the hydraulic oil more uniform, ensuring the stability and reliability of the hydraulic system. The design of the branch pipe 213 makes it only necessary to add or reduce the branch pipe 213 at the corresponding position when it is necessary to increase or reduce the hydraulic actuator, without making major changes to the entire pipeline mechanism 21, thereby simplifying the maintenance process and improving the scalability of the system. Through reasonable pipeline layout and branch pipe 213 design, the pressure loss and leakage risk in the hydraulic pipeline are reduced, and the safety performance of the entire hydraulic station is improved. The optimized pipeline structure reduces the friction loss of the fluid in the pipeline, improves the energy transmission efficiency, and helps to reduce the energy consumption of the system.

[0033] Among them, the pressure detection mechanism 22 is used to detect the pressure during the delivery of hydraulic oil, and the pressure sensor 223 continuously detects the pressure change of the hydraulic system and transmits the data to the control mechanism 23 in real time. The control mechanism 23 displays the received pressure data to the operator through the display screen 233, and adjusts the displacement of the variable pump 3 according to the preset control logic to achieve adaptive pressure regulation of the hydraulic system. At the same time, the pressure display meter 224 also provides an intuitive pressure data display for the operator, so that they can understand the operating status of the hydraulic system at any time. Through this design, the pressure detection mechanism 22 plays a key role in the adaptive pressure regulation hydraulic station and improves the stability and reliability of the hydraulic system. The threaded connection mode of the assembly 225 and the threaded hole 222 makes the installation and adjustment of the pressure sensor 223 and the pressure display meter 224 simple and quick, and improves the work efficiency. The two ends of the connecting cylinder 221 are connected to the opposite ends of the pipeline I 211 and the pipeline II 212 by flanges, which not only ensures the sealing and stability between it and the pipeline. And it is easy to disassemble.

[0034] The design of the assembly 225 facilitates the installation and removal of the pressure sensor 223 and the pressure display gauge 224. The threaded connection between the hollow threaded head 2251 and the threaded hole 222 ensures the tight fit between the assembly 225 and the connecting tube 221. The bolt connection of the two sets of flanges 2252 enhances the overall strength of the assembly 225, so that the pressure detection mechanism 22 can maintain stable performance even in a high-pressure environment. The connection between the hollow threaded head 2251 and the threaded hole 222 can be achieved through a simple rotation action. The bolt connection between the flanges 2252 also facilitates the removal and replacement of the components, reducing the maintenance cost and time of the pressure sensor 223 and the pressure display gauge 224.

[0035] Among them, the control mechanism 23 is used to process the data detected by the pressure detection mechanism 22, and the housing 231 is installed on the surface of the oil tank 1, which is convenient for fixing the control mechanism 23. The pressure of the hydraulic system is monitored and automatically adjusted in real time by the processor 232, realizing the intelligent control of the hydraulic station and improving the work efficiency and accuracy. The display screen 233 can display the pressure data and control status of the hydraulic system in real time, so that the operator can intuitively understand the operation of the system, which is convenient for monitoring and adjustment. The electrical connection between the processor 232 and each component ensures the rapid transmission and processing of information, so that the control mechanism 23 can quickly respond to system changes, adjust the displacement of the variable pump 3, and realize adaptive pressure regulation. First, in the selection of the processor 232, we use a high-performance industrial-grade processor with fast data processing capabilities and powerful control logic. The processor can not only receive the pressure data from the pressure sensor 223 in real time, but also accurately control the variable pump 3 according to the preset to realize the adaptive pressure regulation of the hydraulic system. Secondly, in terms of the display screen 233, we use a high-resolution color touch screen, which can clearly display the pressure curve, control status and fault information of the hydraulic system. The operator can perform operations such as parameter setting, mode switching and fault diagnosis on the control mechanism 23 through the touch screen, which improves the convenience and flexibility of operation.

[0036] The design of the connection mechanism 24 facilitates the connection between the branch pipe 213 and the corresponding diverter valve 4. The welding of the clamping ring 241 and the branch pipe 213, and the clamping connection of the locking nut 242 and the clamping ring 241 ensure the stable connection between the connection mechanism 24 and the branch pipe 213 and the diverter valve 4, effectively preventing the leakage of hydraulic oil. The locking nut 242 and the diverter valve 4 are threadedly connected, so that during the installation and disassembly process, only a simple rotation action is required to complete it, which improves work efficiency. The clamping ring 241 and the locking nut 242 are closely matched to form an effective sealing barrier, ensuring the smooth flow of hydraulic oil in the pipeline and reducing energy loss and environmental pollution caused by leakage.

[0037] The working principle of the adaptive pressure regulating hydraulic station is as follows: when in use, first check whether the equipment can be used normally, and control the variable pump 3 to work through the control mechanism 23, so that the hydraulic oil in the oil tank 1 enters the diverter valve 4 through the pipeline mechanism 21 and the pressure detection mechanism 22, and is distributed by the diverter valve 4. In this process, the pressure sensor 223 and the pressure display meter 224 detect the pressure of the hydraulic oil flowing through the connecting cylinder 221 in real time, and transmit the data to the processor 232, and then the processor 232 processes the received data, and uses the display screen 233 to display the relevant data in real time. When the system processor 232 detects that the workload increases, the pressure sensor 223 will notify the control system, and the processor 232 will increase the output pressure of the variable pump 3 to meet higher work requirements. On the contrary, when the workload decreases, the processor 232 will automatically reduce the output pressure to reduce energy consumption. In this way, the system can realize pressure supply on demand, thereby greatly improving the overall energy utilization efficiency. The processor 232 that adjusts the output pressure of the variable pump 3 according to the pressure data is a product in the prior art and can be obtained by commercial means.

[0038] It should be noted that the specific models and specifications of the variable pump 3, the diverter valve 4, the pressure sensor 223, the pressure display gauge 224, the processor 232, and the display screen 233 need to be selected and determined based on the actual specifications of the device, etc. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0039] The power supply and principles of the variable pump 3, the pressure sensor 223, the pressure display gauge 224, the processor 232, and the display screen 233 are clear to those skilled in the art and will not be described in detail herein.

[0040] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
