Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an online transformer oil monitoring device that is convenient for detection and alarm processing. Background Art

[0002] Transformer oil is a mineral oil obtained through distillation and refining of natural petroleum. It is obtained by acid-base refining of the lubricating oil fraction in petroleum. It can play the role of insulation and heat dissipation. When the transformer oil is in use, the monitoring device can be used to monitor the transformer oil online, so that the different states of the transformer oil can get data feedback in time.

[0003] In the prior art, a Chinese patent with authorization announcement number CN219736488U discloses a transformer oil monitoring mechanism. The novel transformer oil monitoring mechanism has a structure for reinforcing monitoring components. During the monitoring process, the monitoring components will not become loose, so that the monitoring effect is better and the practicability is stronger, which is suitable for wide promotion and use.

[0004] The above-mentioned mechanism utilizes the monitoring mechanism and the reinforcement mechanism to cooperate with each other, so that the monitoring mechanism can be used more stably, the monitoring mechanism will not be loose, and the monitoring effect is stable. However, in actual use, when the hydraulic oil level changes, the monitoring mechanism is not convenient to observe the current level in time, and when the level drops to insufficient, it cannot issue an alarm in time. At the same time, the traditional level sensor is installed in a fixed position, and the level reminder height cannot be adjusted according to different needs, resulting in a decrease in the applicability of the hydraulic press when used. Utility Model Content

[0013] Furthermore, the protective mechanism includes a guide rod, and the guide rod is fixedly connected to the two ends of one side of the protective block, a buffer spring is wound around the outer side of the guide rod, and one end of the buffer spring is fixedly connected to a sliding block, the sliding block is sleeved on the outer side of the guide rod, one side of the sliding block is hinged with a hinged rod, and one side of the hinged rod is hinged with a buffer plate.

[0014] Furthermore, a rubber buffer block is fixedly connected to the middle position of one side of the protection block, and the rubber buffer block is arranged on one side of the buffer plate:

[0015] 1. By rotating the threaded rod, the threaded rod can drive the extension rod to change the height inside the hydraulic oil tank, so that the inside of the hydraulic oil tank can be set with different heights of liquid level reminders, which is convenient for more timely replenishment or replacement of hydraulic oil. When there is sufficient hydraulic oil inside the hydraulic oil tank, the movable float will be affected by buoyancy and drive the connecting rod to float on the surface of the hydraulic oil. When the oil level continues to drop to the liquid level height that needs to be reminded, the two connecting pieces are in contact with each other, thereby realizing information transmission, so that the device can realize timely reminders and alarms of the liquid level height;

Finally, the position of the oil tank cover is reinforced by bolts, so that the overall connection of the oil tank cover can be more stable.

[0017] Furthermore, after the fuel tank cap is wrapped by the sealing mechanism and reinforced by the bolts, the threaded rod can rotate on the fuel tank cap more smoothly, effectively avoiding the situation that the threaded rod drives the fuel tank cap to rotate when rotating;

When the buffer plate is impacted, it will be forced to move to one side, which will change the angle of the hinge rod, and the sliding block will slide on the outside of the guide rod, so that the buffer spring is stressed and shortened, so that the buffer plate can eliminate the impact force, increase the impact resistance of the hydraulic oil tank during use, make the overall use of the hydraulic oil tank more stable, and reduce the damage caused by external impact;

[0019] Furthermore, when the buffer plate is impacted, the rubber buffer block will buffer the force of the impact. The rubber buffer block can reduce the impact force received by the buffer spring during buffering, and also reduce the possibility of damage to the protective block caused by the impact force.

[0031] In this example, by engaging the tank cap 2 on the top of the hydraulic oil tank 1, the tank cap 2 and the threaded rod 3 are threadedly connected, and by rotating the threaded rod 3, the threaded rod 3 can drive the extension rod 4 to change the height inside the hydraulic oil tank 1, so that the inside of the hydraulic oil tank 1 can be set with liquid level reminders at different heights, which is convenient for more timely replenishment or replacement of the hydraulic oil. When there is sufficient hydraulic oil in the hydraulic oil tank 1, the movable float 6 will be affected by the buoyancy and drive the connecting rod 7 to float on the surface of the hydraulic oil. When the oil level continues to drop to the liquid level height that needs to be reminded, the two connecting pieces 8 are in contact with each other, thereby realizing information transmission, so that the device can realize liquid level height reminders and alarms in time.

[0032] Embodiment 2:

[0033] like Figure 1 , Figure 2 , Figure 6 and Figure 7 The technical solution shown is based on the first embodiment, in order to solve the problem that leakage is easy to occur when installing the oil tank cover 2, causing the hydraulic oil inside the hydraulic oil tank 1 to easily spill due to vibration: the transformer oil online monitoring device that is easy to detect and alarm processing discloses a sealing mechanism, the top of the hydraulic oil tank 1 is fixedly connected to the limit block 10, and the limit block 10 is provided with a sealing mechanism for sealing and wrapping the oil tank cover 2, the sealing mechanism includes a first airbag 11, and the first airbag 11 is fixedly connected to the bottom end inside the limit block 10, the top of the first airbag 11 is fixedly connected to the second airbag 13 through a hose 12, the second airbag 13 is arranged at the upper end of the outer side of the limit block 10, and the cross-section of the second airbag 13 is an inverted "L" shape.

[0034] In this example, the tank cap 2 is arranged at the top of the limit block 10, so that the protrusion at the bottom end of the tank cap 2 can be squeezed and contacted with the limit block 10, and the first air bag 11 inside the limit block 10 is squeezed, and the internal gas is transported to the inside of the second air bag 13 through the hose 12, thereby sealing and squeezing the upper end of the protrusion on the outer side of the tank cap 2, so that the sealing performance of the connection between the tank cap 2 and the hydraulic oil tank 1 is stronger, which can better prevent the hydraulic oil inside the hydraulic oil tank 1 from spilling, and increase the applicability of the hydraulic oil tank 1 when in use. Finally, the position of the tank cap 2 is reinforced with bolts, so that the overall connection of the tank cap 2 can be more stable. At the same time, after the tank cap 2 is wrapped by the sealing mechanism and reinforced with bolts, the threaded rod 3 can also rotate on the tank cap 2 more smoothly, effectively avoiding the situation where the threaded rod 3 drives the tank cap 2 to rotate when rotating.

[0037] In this example, when the buffer plate 19 is impacted, the rubber buffer block 18 will buffer the force of the impact. At the same time, the buffer plate 19 is forced to move to one side, which will change the force angle of the hinge rod 17, and the sliding block 16 slides on the outside of the guide rod 14, so that the buffer spring 15 is stressed and shortened in length, so that the buffer plate 19 can eliminate the impact force, increase the impact resistance of the hydraulic oil tank 1 during use, make the overall use of the hydraulic oil tank 1 more stable, and reduce damage caused by external impact.
