[0018] The utility model provides an energy-saving hydraulic station: comprising an installation cavity 101, a hydraulic pump 102 and an electric signal receiving end 103, wherein the hydraulic pump 102 is arranged inside the installation cavity 101, the electric signal receiving end 103 is fixedly connected to the hydraulic pump 102 and is located at the upper end of the hydraulic pump 102, and the electric signal receiving end 103 is adapted to the hydraulic pump 102, and the electric signal receiving end 103 is used to receive the electric signal and control the hydraulic pump 102 through the electric signal, and further comprising an oil supply pipe 104, a first three-way solenoid valve 105, The first oil pressure pipe 106, the second oil pressure pipe 107, the second three-way solenoid valve 108 and the oil outlet pipe 109, the oil supply pipe 104 is connected to the output end of the hydraulic pump 102 and is located at one end of the hydraulic pump 102, the first three-way solenoid valve 105 is connected to the oil supply pipe 104 and is located at one end of the oil supply pipe 104, the first oil pressure pipe 106 and the second oil pressure pipe 107 are respectively connected to the first three-way solenoid valve 105 and are located at one end of the first three-way solenoid valve 105, the second three-way solenoid valve 108 is connected to the first three-way solenoid valve 109 and is located at one end of the first three-way solenoid valve 105. An oil pressure pipe 106 is connected to the second oil pressure pipe 107 and is located at one end of the first oil pressure pipe 106 and the second oil pressure pipe 107. The oil outlet pipe 109 is connected to the second three-way solenoid valve 108. The installation cavity 101 is used to install the hydraulic pump 102 and the electrical signal receiving end 103. The electrical signal receiving end 103 is adapted to the hydraulic pump 102 to suck the hydraulic oil and pump the hydraulic oil into the first three-way solenoid valve 105 through the oil supply pipe 104. The oil circuit is regulated by the first three-way solenoid valve 105. The hydraulic oil is connected to the second three-way solenoid valve 108 through the first three-way solenoid valve 105 and the first oil pressure pipe 106, and finally the hydraulic oil is pumped into the corresponding output device by the oil outlet pipe 109. When cleaning the oil circuit, the first three-way solenoid valve 105 and the second three-way solenoid valve 108 are regulated to make the second oil pressure pipe 107 connected, and the first oil pressure pipe 106 is closed.

[0019] The oil supply pipe 104 includes a pipe body 110, a speed change inner pipe 111, a limiting ring 112 and a limiting rib 113. The limiting ring 112 is fixedly connected to the pipe body 110 and embedded in the interior of the pipe body 110. The limiting rib 113 is a plurality of pieces, each of which is fixedly connected to the pipe body 110 and located in the interior of the pipe body 110. The speed change inner pipe 111 is embedded in the interior of the pipe body 110, and the speed change inner pipe 111 is fixedly connected to the pipe body 110.

The increase in the flow rate of the hydraulic oil can reduce the accumulation and formation of oil residue, reduce the increase in energy consumption during use, and achieve energy-saving effects.

[0020] Secondly, the oil outlet pipe 109 has the same structure as the oil supply pipe 104, and the installation direction of the oil outlet pipe 109 is the same as that of the oil supply pipe 104. The oil outlet pipe 109 also increases the speed of the hydraulic oil when discharging the hydraulic oil, thereby avoiding the formation and accumulation of oil residue in the oil outlet pipe 109, thereby reducing the energy consumption of the oil circuit operation and achieving the purpose of energy saving.

[0021] At the same time, the energy-saving hydraulic station also includes a pressure detector 114, and the number of the pressure detectors 114 is multiple groups.

The number of the support columns 115 is multiple groups, and each group of the support columns 115 is fixedly connected to the installation cavity 101 and is respectively located at the upper end of the installation cavity 101. The number of the arc plates 116 is multiple groups, and each group of the arc plates 116 is fixedly connected to the corresponding support columns 115 and is respectively located at the upper end of the corresponding support columns 115. Each group of the arc plates 116 is adapted to the corresponding first oil pressure tube 106 and the second oil pressure tube 107. The arc plates 116 are supported and fixed by the support columns 115, and the first oil pressure tube 106 and the second oil pressure tube 107 are supported and fixed by the arc plates 116, so as to ensure that the first oil pressure tube 106 and the second oil pressure tube 107 are stably supported during operation.

[0023] When using an energy-saving hydraulic station of this embodiment, the installation cavity 101 is used to house the hydraulic pump 102 and the electrical signal receiving end 103. The electrical signal receiving end 103 is adapted to the hydraulic pump 102 to suck the hydraulic oil and pump the hydraulic oil into the first three-way solenoid valve 105 through the oil supply pipe 104. The oil circuit is connected through the first three-way solenoid valve 105 and is passed into the second three-way solenoid valve 108 through the first three-way solenoid valve 105 and the first oil pressure pipe 106. Finally, the hydraulic oil is pumped into the corresponding output device through the oil outlet pipe 109. When cleaning the oil circuit, the first three-way solenoid valve 105 and the second three-way solenoid valve 108 are regulated so that the second oil pressure pipe 107 is connected and the first oil pressure pipe 106 is closed. The first oil pressure pipe 106 can be disassembled and cleaned, and the oil circuit can be cleaned during operation to avoid excessive accumulation of oil residue, which affects the use of the oil circuit. The limit ring 110 is controlled by the tube body 110. 2 and the limiting rib 113 are installed and fixed, and the gear shift inner tube 111 is embedded in the interior of the tube body 110. The input end of the gear shift inner tube 111 is larger than the output end. Since the total amount of hydraulic oil input remains unchanged and the inner diameter of the pipe changes, the flow rate of the hydraulic oil will increase. The increase in the flow rate of the hydraulic oil can reduce the accumulation and formation of oil residue, reduce the increase in energy consumption during use, and achieve energy saving effects. The oil outlet pipe 109 also accelerates the hydraulic oil when discharging the hydraulic oil to avoid the formation and accumulation of oil residue at the oil outlet pipe 109, which can reduce the energy consumption of the oil circuit operation and achieve energy saving purposes. The oil pressure in the oil circuit can be detected in real time by the pressure detector 114, and corresponding operations and operations can be performed according to the oil pressure data. The curved plate 116 is supported and fixed by the support column 115, and the first oil pressure pipe 106 and the second oil pressure pipe 107 are supported and fixed by the curved plate 116 to ensure that the first oil pressure pipe 106 and the second oil pressure pipe 107 are stably supported during operation.
