Description

Technical Field

[0001] The utility model relates to the technical field of leakage oil recovery, in particular to a leakage oil recovery device for a hydraulic station. Background Technique

[0002] A hydraulic station is a hydraulic source device composed of a hydraulic pump, a driving electric motor, an oil tank, a directional valve, a throttle valve, an overflow valve, etc. or a hydraulic device including a control valve. In a wind power plant, the hydraulic station is located in the wild. During its operation, oil leakage occurs. If not discovered in time, it is easy to cause soil pollution around, and the waste of hydraulic oil is serious. In order to avoid soil pollution, a leakage oil recovery device is used to recover the leakage oil.

[0003] When the existing leakage oil recovery device recovers the leakage oil, since the leakage oil contacts the air after leaking out, more particulate impurities are contained in the leakage oil, resulting in poor quality of the leakage oil recovered by the leakage oil recovery device.

[0004] In the patent document with the publication number of CN220929852U, a leakage oil recovery device for a fan hydraulic station is disclosed. Through a box body and a filter screen structure, a hose guides the leakage oil into the box body. The leakage oil introduced into the box body falls on the filter screen. The filter screen filters the leakage oil introduced by the hose, filters out the particulate impurities in the leakage oil, reduces the particulate impurities in the leakage oil, and improves the quality of the leakage oil after recovery.

[0005] However, when the leakage oil recovery device for the fan hydraulic station filters the leakage oil, the oil naturally passes through the filter screen for filtration. At this time, the filtration efficiency is low, and the impurities will remain on the top of the filter screen after the oil is filtered, and the filter screen needs to be cleaned in time. Therefore, a leakage oil recovery device for a hydraulic station with high efficiency needs to be proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 4 , the present utility model provides a technical solution:

[0025] Embodiment 1:

[0026] A hydraulic station leakage oil recovery device, including a filter tank 1 and side plates 2 arranged on the outer surface of the filter tank 1. A filtering mechanism is arranged inside the filter tank 1, and a limiting mechanism is arranged on one side of the side plate 2;

[0027] The filtering mechanism includes a mounting plate 101, a fixing plate 102, a rope 103, a fixing seat 104, a pressing plate 105, a telescopic rod 106, a first spring 107, a connecting seat 108, a guiding seat 109, a soft sleeve 110 and a motor 111. The mounting plate 101, the fixing plate 102 and the connecting seat 108 are all fixedly connected to the inner wall of the filter tank 1. The rope 103 is fixedly connected to the bottom of the fixing plate 102. One end of the rope 103 is fixedly connected to the bottom of the fixing plate 102, and the other end is fixedly connected to a pulley arranged at the output end of the motor 111. When the motor 111 is started, the rope 103 can be wound onto the pulley at the output end of the motor 111. The telescopic rod 106 is fixedly connected to the bottom of the mounting plate 101. The first spring 107 is movably connected to the outside of the telescopic rod 106. The pressing plate 105 is fixedly connected to the bottom of the telescopic rod 106. Fixing seats 104 are fixedly connected to both sides of the pressing plate 105. A rotating shaft is arranged on one side of the fixing seat 104. The rope 103 is located outside the rotating shaft. The fixing seat 104 is fixedly connected to one side of the telescopic rod 106. The guiding seat 109 is arranged on one side of the filter tank 1. The soft sleeve 110 is arranged at the bottom of the connecting seat 108. The rope 103 sequentially passes through the soft sleeve 110, the connecting seat 108 and the guiding seat 109. The soft sleeve 110 is arranged such that when the oil-soaked rope 103 is pulled out, the attached oil can be scraped off. The motor 111 is arranged on one side of the filter tank 1. The leakage oil is put into the inside of the oil delivery pipe 3 from the opening at the top of the oil delivery pipe 3, and through the guide plate 4, the oil can uniformly enter the inside of the filter tank 1. When the oil enters the inside of the filter tank 1, it slides down along the side surface of the pressing plate 105 to the top of the filter net 202, and is filtered by the filter net 202 into the fuel tank 5 inside. The motor 111 will wind the rope 103 onto the output end of the motor 111, and the entire pressing plate 105 will move upward. At this time, the first spring 107 is compressed by force, and the oil is located at the bottom of the pressing plate 105. When the motor 111 rotates in reverse, the rope 103 wound on the output end of the motor 111 will be gradually released. Since the compressed first spring 107 will generate a restoring force under the action of its own restoring force and act on the top of the pressing plate 105, the pressing plate 105 will slowly move downward. At this time, the oil located at the bottom of the pressing plate 105 will be filtered by the filter net 202 more quickly under the pressure of the pressing plate 105 and flow down into the fuel tank 5 inside.

[0028] Embodiment Two:

[0029] On the basis of the first embodiment, the limiting mechanism includes a sealing plate 201, a filter screen 202, a first handle 203, a limiting rod 204, a limiting block 205, a second handle 206 and a second spring 207. The sealing plate 201 is arranged inside the filter box 1. The filter screen 202 is arranged on one side of the sealing plate 201. The first handle 203 is fixedly connected to one side of the sealing plate 201. The limiting rod 204 is arranged on one side of the side plate 2. A through hole matching with the limiting rod 204 is formed through one side of the side plate 2. A groove matching with the limiting block 205 is formed at the bottom of the side plate 2. When the second handle 206 is pulled upward so that the limiting block 205 is located on the inner wall of the groove, the restriction on the sealing plate 201 can be released, and then the sealing plate 201 can be disassembled. The second handle 206 is fixedly connected to the top of the limiting rod 204. The limiting block 205 is fixedly connected to the bottom of the limiting rod 204. The second spring 207 is movably connected to the outside of the limiting rod 204. The filter screen 202 can be disassembled and replaced. After being used for a period of time, the second handle 206 is pulled upward. At this time, the second spring 207 is compressed by force, and the limiting block 205 is pulled into the inner wall of the groove formed on one side of the side plate 2. At this time, when the first handle 203 is pulled, the first handle 203 can be disassembled, and then the filter screen 202 can be disassembled to clean the filter screen 202. The first handle 203 is moved into the side plate 2. After reaching the position, the second handle 206 is released. The second spring 207 returns to the bottom under the action of its resilience. At this time, the limiting block 205 can limit the sealing plate 201.

[0030] An oil delivery pipe 3 is fixedly connected to the top of the filter box 1. A flow guide plate 4 is arranged on the inner wall of the oil delivery pipe 3. The flow guide plate 4 is arranged so that the oil liquid inside the oil delivery pipe 3 can uniformly fall into the filter box 1. A fuel tank 5 is arranged at the bottom of the filter box 1. A footrest 7 is fixedly connected to the bottom of the fuel tank 5. Four footrests 7 are evenly distributed. A discharge pipe 6 is arranged on one side of the fuel tank 5.

[0031] Working principle:

[0032] First of all, through the arranged filtering mechanism, the leaked oil is put into the oil delivery pipe 3 from the opening at the top of the oil delivery pipe 3. On the way, it passes through the flow guide plate 4 so that the oil liquid can uniformly enter the filter box 1. When the oil liquid enters the filter box 1, it will slide down along the side surface of the pressing plate 105 to the top of the filter screen 202 and is filtered into the fuel tank 5 by the filter screen 202.

[0033] Furthermore, after the motor 111 is started, the rope 103 will be wound onto the output end of the motor 111. When the rope 103 is wound, the entire pressing plate 105 will move upward. At this time, the first spring 107 is compressed by force, and the oil liquid is located at the bottom of the pressing plate 105.

[0034] Further, when the motor 111 rotates in reverse, the rope 103 wound around the output end of the motor 111 will be gradually released. Since the compressed spring 107 will generate a resilience force under the action of its own restoring force and act on the top of the pressing plate 105, the pressing plate 105 will slowly move downward. At this time, the hydraulic oil located at the bottom of the pressing plate 105 will be filtered more quickly by the filter screen 202 under the pressure of the pressing plate 105 and flow down into the fuel tank 5. This process will repeat. When the hydraulic oil is located at the bottom of the pressing plate 105 and the pressing plate 105 moves downward under the action of the spring 107, the hydraulic oil will quickly pass through the filter screen 202, and the particulate impurities in the hydraulic oil will be filtered out.

[0035] Further, through the set limit mechanism, the filter screen 202 can be disassembled and replaced. After using it for a period of time, pull up the handle 206. At this time, the spring 207 is compressed by force, and the limit block 205 is pulled into the inner wall of the groove opened on one side of the side plate 2. At this time, pulling the handle 203 can disassemble the handle 203, and then disassemble the filter screen 202 to clean the filter screen 202 to achieve the best filtering effect.

[0036] Furthermore, after cleaning, move the handle 203 into the side plate 2. After reaching the position, release the handle 206. The spring 207 will return to the bottom under the action of its resilience force. At this time, the limit block 205 can limit the sealing plate 201.
