Description

Technical Field

[0001] This utility model relates to the field of hydraulic equipment technology, and in particular to a protection device for a hydraulic station. Background Technology

[0002] In hydraulic transmission and control systems, the hydraulic power unit, as the core power source, is crucial to the overall performance of the equipment. Its stable operation directly impacts production efficiency and equipment safety, making its protection paramount. Hydraulic oil, the core medium in the hydraulic system, is considered its "blood," and its cleanliness decisively affects the performance and lifespan of hydraulic components. Impurities, particles, or contaminants in the hydraulic oil can cause wear, jamming, or even malfunction of hydraulic components, threatening the normal operation of the hydraulic power unit. Therefore, maintaining the cleanliness of the hydraulic oil is a key measure for protecting the hydraulic power unit. However, existing oil filtration devices have significant shortcomings in practical use. The replacement and maintenance of filter membranes are complex, typically requiring professional personnel, resulting in high maintenance costs and long operating times, failing to meet the demands of high-efficiency production. Furthermore, when the hydraulic power unit experiences sudden load changes or operational errors, the oil pressure may momentarily exceed the design range. Without effective pressure protection measures, hydraulic components will be subjected to excessive pressure, leading to damage and even safety accidents. Although some hydraulic stations are equipped with pressure protection devices, they have defects such as delayed response and untimely pressure relief, which cannot fully meet the safety protection requirements of hydraulic stations. In view of this, it is necessary to improve the current hydraulic stations to solve the above problems.

[0003] The information disclosed in this background section is only for understanding the background technology of the inventive concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0004] The purpose of this invention is to provide a protection device for a hydraulic power station, addressing the issue raised in the background art where hydraulic oil, as the core medium of the hydraulic system and considered the "blood" of the system, has a decisive impact on the performance and lifespan of hydraulic components. If impurities, particulate matter, or contaminants are mixed into the hydraulic oil, it can lead to wear, jamming, or even malfunction of hydraulic components, thus threatening the normal operation of the hydraulic power station. Therefore, maintaining the cleanliness of the hydraulic oil is one of the key measures for protecting the hydraulic power station. However, the oil filtration devices in related technologies have significant shortcomings in practical use. The replacement and maintenance of the filter membrane is complex, usually requiring professional personnel, resulting in high maintenance costs and long operating times, making it difficult to meet the needs of high-efficiency production. Furthermore, when the load on the hydraulic power station changes suddenly or due to operational errors, the oil pressure may instantly exceed the design range. Without effective pressure protection measures, hydraulic components will be subjected to excessive pressure and damaged, even leading to safety accidents. Currently, although some hydraulic power stations are equipped with pressure protection devices, they suffer from defects such as delayed response and untimely pressure relief, failing to fully meet the safety protection requirements of the hydraulic power station.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protection device for a hydraulic station includes a fixed frame, a platform, an oil pump motor, and a pump body. The platform is fixedly installed on the upper end of the fixed frame, and the oil pump motor is fixedly installed on the upper end of the platform. One side of the oil pump motor is connected to the pump body, and one side of the pump body is connected to an oil delivery seat via an oil pipe. The lower end of the oil pipe is fixedly connected to a fixed seat. Threaded seats are symmetrically arranged on the upper end of the fixed seats, and fastening bolts are threadedly connected to the fixed seats through the threaded seats. The inner wall of the fixed seat is provided with internal threads. An oil filter tank is provided at the lower end of the fixed seat, and the upper end of the oil filter tank is provided with external threads. The external threads of the oil filter tank are connected to the internal threads of the fixed seat, and a filter membrane is installed inside the oil filter tank.

[0007] As a preferred technical solution, one side of the oil pipe is connected to an oil supply seat, the upper end of the oil supply seat is equipped with an oil inlet, the other side of the oil supply seat is equipped with a lower oil inlet, and the upper end of the oil supply seat is equipped with a first pressure gauge.

[0008] As a preferred technical solution, a pressure relief pipe is installed at the upper end of the pump body, a pressure relief valve is connected to one side of the pressure relief pipe, the pressure relief valve is installed on one side of the fixed frame, and the pressure relief pipe is connected to a second pressure gauge.

[0009] As a preferred technical solution, a controller is fixedly installed on the upper end of the platform, and a button is installed on one side of the controller. The controller is electrically connected to the oil pump motor, pump body, first pressure gauge, second pressure gauge, and button.

[0010] The beneficial effects of this utility model are:

[0011] This device connects the oil filter tank to the internal thread of the mounting base via its external thread. Hydraulic oil is filtered through a filter membrane inside the tank before entering the pump body. The threaded connection of the oil filter tank is both secure and easy to disassemble. When the filter membrane needs replacement, simply unscrew the oil filter tank. The filter membrane effectively filters impurities from the hydraulic oil, maintaining its cleanliness, reducing wear on hydraulic components, thus protecting the normal operation of the hydraulic power unit and extending its service life.

[0012] Furthermore, when the hydraulic pressure exceeds the set value, the pressure relief valve will automatically open to discharge the excess hydraulic oil through the pressure relief pipe, thereby reducing the pressure of the hydraulic station, protecting the hydraulic components from damage, and further ensuring the safety of the hydraulic station.

[0020] Reference Figure 1-3 A protection device for a hydraulic station includes a fixed frame 1, a platform 2, an oil pump motor 3, and a pump body 4. The platform 2 is fixedly installed on the upper end of the fixed frame 1, and the oil pump motor 3 is fixedly installed on the upper end of the platform 2. One side of the oil pump motor 3 is connected to the pump body 4, and one side of the pump body 4 is connected to an oil supply seat 6 through an oil pipe 5. One side of the oil pipe 5 is connected to the oil supply seat 6. An upper oil port 8 is installed on the upper end of the oil supply seat 6, and a lower oil port 9 is installed on one side of the oil supply seat 6. A first pressure gauge 7 is installed on the upper end of the oil supply seat 6.

[0021] With this design, hydraulic oil can be stably delivered from pump body 4 to oil supply seat 6 through oil pipe 5. The upper oil port 8 and lower oil port 9 on oil supply seat 6 are used for hydraulic oil input and output, respectively.

[0022] After the pump body 4 pressurizes the hydraulic oil, it is delivered to the oil supply seat 6 through the oil pipe 5. The hydraulic oil can be delivered to the external hydraulic device through the lower oil port 9, and the hydraulic oil can flow back to the pump body 4 through the upper oil port 8, thereby realizing the circulation of hydraulic oil.

[0023] Meanwhile, the first pressure gauge 7 installed on the oil supply seat 6 can monitor the hydraulic oil pressure in the oil supply seat 6 in real time, making the hydraulic oil delivery process more convenient and controllable. The real-time monitoring function of the first pressure gauge 7 can ensure that the hydraulic system operates within a safe pressure range, avoiding equipment damage or safety accidents caused by excessive or insufficient pressure.

[0024] The lower end of the oil pipe 5 is fixedly connected to the fixing seat 10. The upper end of the fixing seat 10 is symmetrically provided with threaded seats 105. The fastening bolt 106 is threadedly connected to the fixing seat 101 through the threaded seats 105. The inner wall of the fixing seat 101 is provided with internal threads 103. The lower end of the fixing seat 101 is provided with an oil filter tank 11. The upper end of the oil filter tank 11 is provided with external threads 102. The external threads 102 of the oil filter tank 11 are connected to the internal threads 103 of the fixing seat 101. A filter membrane 104 is installed inside the oil filter tank 11.

[0025] Through this design, the lower end of the oil pipe 5 is fixedly connected to the fixed seat 10. The fixed seat 10 is tightly connected to the fixed seat 101 through symmetrically arranged threaded seats 105 and fastening bolts 106, ensuring the stability and sealing of the oil pipe 5 during use. The oil filter tank 11 is threadedly connected to the internal thread 103 of the fixed seat 101 through its external thread 102 at the upper end. Before entering the pump body 4, the hydraulic oil is filtered through the filter membrane 104 inside the oil filter tank 11. The threaded connection of the oil filter tank 11 is both firm and easy to disassemble. When the filter membrane 104 needs to be replaced, the operation can be completed simply by unscrewing the oil filter tank 11. The filter membrane 104 effectively filters impurities in the hydraulic oil, maintains the cleanliness of the hydraulic oil, reduces wear on hydraulic components, thereby protecting the normal operation of the hydraulic station and extending the service life of the hydraulic station.

[0026] In other embodiments, a pressure relief pipe 501 is installed at the upper end of the pump body 4, and a pressure relief valve 12 is connected to one side of the pressure relief pipe 501. The pressure relief valve 12 is installed on one side of the fixing frame 1, and the pressure relief pipe 501 is connected to a second pressure gauge 13.

[0027] With this design, during the operation of the hydraulic station, the first pressure gauge 7 and the second pressure gauge 13 will detect the oil pressure in the pipe. When the oil pressure exceeds the set value, the pressure relief valve 12 will automatically open to discharge the excess hydraulic oil through the pressure relief pipe 501, thereby reducing the pressure of the hydraulic station, protecting the hydraulic components from damage, and further ensuring the safety of the hydraulic station.

[0028] In other embodiments, a controller 14 is fixedly installed on the upper end of the platform 2, and a button 15 is installed on one side of the controller 14. The controller 14 is electrically connected to the oil pump motor 3, the pump body 4, the first pressure gauge 7, the second pressure gauge 13, and the button 15.

[0029] Example 1

[0030] The operator starts the oil pump motor 3 via button 15, and the pump body 4 begins to work. Hydraulic oil is delivered to the oil supply seat 6 through the oil pipe 5, and forms a hydraulic oil circulation through the upper oil port 8 and the lower oil port 9. The first pressure gauge 7 monitors the pressure in the oil supply seat 6, and the second pressure gauge 13 monitors the pressure in the pressure relief pipe 501. When the oil pressure is too high, the pressure relief valve 12 automatically opens, and the excess hydraulic oil is discharged through the pressure relief pipe 501 to protect the system safety. The controller 14 receives the pressure data in real time and adjusts the operating parameters as necessary.

[0031] In this embodiment, the oil filter tank 11 is threadedly connected to the internal thread 103 of the fixed seat 101 via its external thread 102. Before entering the pump body 4, the hydraulic oil is filtered through the filter membrane 104 inside the oil filter tank 11. The threaded connection of the oil filter tank 11 is both secure and easy to disassemble. When the filter membrane 104 needs to be replaced, the operation can be completed simply by unscrewing the oil filter tank 11. The filter membrane 104 effectively filters impurities in the hydraulic oil, maintains the cleanliness of the hydraulic oil, reduces wear on hydraulic components, thereby protecting the normal operation of the hydraulic station and extending its service life.

[0032] Furthermore, when the hydraulic pressure exceeds the set value, the pressure relief valve 12 will automatically open to discharge the excess hydraulic oil through the pressure relief pipe 501, thereby reducing the pressure of the hydraulic station, protecting the hydraulic components from damage, and further ensuring the safety of the hydraulic station.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
