Description

Technical Field

[0001] The utility model relates to the field of hydraulic oil system monitoring, in particular to an oil and pollution online monitoring system applied to an offshore hoisting platform. Background Art

[0002] Hydraulic oil is like blood in the human body. Its various physical and chemical characteristics can also reflect the operating conditions of various components of the unit. For example, the trend of trace wear metal content can reflect the wear condition of equipment (bearings); whether the cleanliness meets the standard, whether it absorbs dissolved water, and whether the oxidation is accelerated directly affect the working accuracy of the fire-resistant oil system and whether an emergency shutdown will occur. Therefore, factories generally regularly test and analyze the chemical and physical properties of oil products.

[0003] Existing testing of hydraulic oil is often completed during cleaning and maintenance of mechanical equipment. Workers will extract samples from the oil and take them to the laboratory for testing. However, laboratory oil testing can only provide the current state of the oil, and cannot provide the trend of oil quality changes. It can only be used as a criterion for finding the cause of equipment failure.

[0004] However, hydraulic oil is inevitably affected by various factors, such as water contamination, mechanical impurities, and other external contaminants. Furthermore, the oil itself can oxidize and deteriorate under high-temperature, high-pressure, and heavy-load operating conditions. In severe cases, this can lead to serious accidents such as burnt bearings, shaft bending, rotor friction, and even complete damage. The sudden accumulation or increase in the short term of external or internal water and contaminants, such as these, can cause premature wear and failure of equipment, which cannot be predicted through routine inspections. Furthermore, inspection reports often have a significant lag and may not reflect actual operating conditions. Utility Model Content

[0005] In order to facilitate the detection of hydraulic oil tanks and thus understand the equipment operating status in real time, the present application provides an online oil and pollution monitoring system for offshore lifting platforms.

[0006] The present application provides an online oil and pollution monitoring system for offshore hoisting platforms, which adopts the following technical solutions:

[0007] An online oil and pollution monitoring system for an offshore lifting platform includes a monitoring unit, a fine filtering unit, and several connecting pipes. The connecting pipes are used to transmit the hydraulic oil in a hydraulic oil tank to the monitoring unit or the fine filtering unit. The hydraulic oil tank, the monitoring unit, and the fine filtering unit are all provided with connecting sockets for connecting to the ends of the connecting pipes. The fine filtering unit is used to finely filter the hydraulic oil in the hydraulic oil tank. The monitoring unit is used to monitor the hydraulic oil in the hydraulic oil tank and start the fine filtering unit when an abnormality is detected in the hydraulic oil.

[0008] By adopting the above technical solution, the hydraulic oil is directly transmitted to the monitoring unit through a connecting pipe, and the oil is monitored in real time, which omits cumbersome operating procedures and avoids additional external pollution. The viscosity, moisture, cleanliness and other parameters of the used oil are continuously and uninterruptedly monitored in situ. The operating conditions and status of the system or equipment are determined or predicted based on the changes in the monitored parameters of the reused oil, and abnormal components of the system or equipment are diagnosed to provide a basis for carrying out targeted maintenance and repairs. When necessary, the hydraulic oil is introduced into the fine filter unit to filter the hydraulic oil and remove impurities therein.

[0009] Preferably, each of the connecting pipes is provided with a connecting plug, the connecting seat is provided with a slot along the circumferential direction, the connecting plug is inserted into the connecting seat through the slot, and the connecting seat is provided with a locking piece for locking the connecting plug installed on the connecting seat.

[0010] By adopting the above technical solution, the connecting plug is directly inserted into the connecting seat, and then the locking piece is activated to lock the connecting plug on the connecting seat. This design can quickly install the connecting pipe on each unit, and use the locking piece to ensure that the connecting pipe is stably installed on each unit, thereby realizing stable transmission of hydraulic oil.

[0011] Preferably, the locking member includes a plurality of locking rods, and the connecting seat is provided with a plurality of first sliding grooves along the circumferential direction on the side wall of the slot, and one locking rod corresponds to one first sliding groove; the locking rod is slidably installed on the connecting seat through the corresponding first sliding groove, and an elastic member is sleeved on the locking rod, one end of the elastic member is installed on the locking rod, and the other end is installed on the bottom of the first sliding groove; a guide surface is provided at one end of the locking rod away from the elastic member, and a plurality of abutting grooves are provided on the outer side wall of the connecting plug along the circumferential direction, and the end of the locking rod away from the elastic member is used to be inserted into the connecting plug through the abutting groove.

[0012] By adopting the above technical solution, after the connecting plug is inserted into the connecting seat, the locking rod is driven to move toward the bottom of the first slide groove under the action of the guide surface, so that the connecting plug is smoothly inserted into the slot of the connecting seat. When the connecting pipe is inserted into the predetermined position, the locking rod is opposite to the abutment groove on the connecting plug. At this time, under the action of the elastic member, the locking rod slides in the first slide groove and is inserted into the abutment groove, completing the locking of the connecting plug; this structure only needs to directly insert the connecting pipe into the connecting seat to complete the locking of the connecting pipe by the connecting seat, which is convenient for workers to quickly complete the installation of the connecting pipe.

[0013] Preferably, the connecting seat is provided with an air bag at the bottom of the slot, and the side of the connecting plug away from the pipe abuts against the air bag.

[0014] By adopting the above technical solution, after the connecting plug is inserted into the connecting seat through the slot, the airbag is pressed against the airbag so that the airbag deforms and extends in the slot, thereby blocking the gap between the connecting plug and the connecting seat, reducing the risk of hydraulic oil leakage from the gap.

[0015] Preferably, the monitoring unit, the fine filtration unit and the hydraulic oil tank are all provided with an isolation chamber, each of the isolation chambers is provided with a liquid outlet, the connecting seat is installed on the isolation chamber through the liquid outlet, a second slide groove is provided on the inner wall of the isolation chamber, and the isolation chamber is slidably installed with a closing plate in the second slide groove, and the closing plate closes the liquid outlet after sliding.

[0016] By adopting the above technical solution, when installing the connecting pipe, the closing plate is first slid to close the liquid outlet. At this time, the hydraulic oil in each unit is difficult to leak through the liquid outlet, reducing the risk of leakage when installing the connecting pipe.

[0017] Preferably, the closing bin is provided with a driving assembly for driving the closing plate to slide.

[0018] By adopting the above technical solution, the driving assembly is used to reduce the workload of manually driving the closing plate to slide, and the sliding stability of the closing plate is improved.

[0019] Preferably, a push rod is slidably installed on the isolation chamber, a sliding hole is opened on the connecting seat, one end of the push rod is passed through the sliding hole into the connecting seat and abuts against the airbag; the driving component is also used to drive the push rod to slide on the isolation chamber.

[0020] By adopting the above technical solution, the driving component drives the push rod to slide again and then press against the airbag, further driving the airbag to be compressed and deformed, filling the gap between the connecting plug and the connecting seat, thereby further reducing the risk of hydraulic oil leakage from this place.

[0021] Preferably, the driving assembly includes a cylinder, a driving rack, a connecting rod and a gear, a driving groove is provided on the isolation chamber, and the driving rack is slidably installed on the isolation chamber through the driving groove; the isolation chamber is provided with a rotating groove, the rotating groove is connected to the driving groove, and the gear is rotatably installed on the isolation chamber through the rotating groove, and the driving rack is engaged with the gear; the rotating groove is connected to the second sliding groove, and a driven rack is provided on the closing plate, and the driven rack is engaged with the other side of the gear relative to the driving rack; the connecting rod is fixed on the side of the driving rack away from the gear, and the end of the connecting rod away from the driving rack is connected to the push rod; the cylinder is fixed on the outer wall of the isolation chamber, and the output end of the cylinder is connected to the end of the push rod away from the connecting seat.

[0022] By adopting the above technical solution, the cylinder is started, driving the push rod to move toward the connecting pipe and then pass through the connecting seat to abut the airbag; at the same time, during the sliding process of the push rod, the driving rack is driven by the connecting rod to move toward the connecting pipe, thereby driving the gear engaged with the driving rack to rotate. After the gear rotates, the driven rack located on the side of the gear away from the driving rack moves in the opposite direction of the moving direction of the driving rack under the action of the gear, that is, moves toward the direction away from the connecting pipe, retracts into the wall of the isolation chamber, and no longer closes the liquid outlet, so that the hydraulic oil can be stably output to the connecting pipe, reducing the risk of hydraulic oil leakage when installing the connecting pipe.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Use connecting pipes to directly transmit hydraulic oil to the monitoring unit for real-time oil monitoring, eliminating cumbersome operating procedures and avoiding additional external contamination. Continuous and uninterrupted in-situ monitoring of parameters such as viscosity, moisture, and cleanliness of the used oil is performed. Based on the changes in the monitored parameters of the used oil, the operating conditions and status of the system or equipment can be determined or predicted, and abnormal components of the system or equipment can be diagnosed, providing a basis for targeted maintenance and repairs. When necessary, the hydraulic oil is introduced into the fine filter unit to filter the hydraulic oil and remove impurities.

[0025] 2. Use a sliding closing plate to seal the outlet to reduce the risk of hydraulic oil leakage from the outlet when installing the connecting pipe;

[0026] 3. Use the driving assembly to drive the ejector rod and the closing plate to move synchronously. When the connecting pipe is not installed, the cylinder drives the ejector rod to move away from the connecting seat, and then, under the linkage of the driving rack, gear and driven rack, drives the closing plate to protrude out of the second slide groove to close the liquid outlet; after the connecting pipe is installed, the cylinder drives the ejector rod to move and press against the airbag, and synchronously drives the closing plate to retract into the second slide groove, thereby blocking the gap between the connecting plug and the connecting seat and releasing the closing plate from the liquid outlet.
