Abstract
Description
Technical Field
[0001] This utility model belongs to the field of research and development and manufacturing technology of external oil-type corrugated metal oil tanks, specifically an external oil-type corrugated metal oil tank with visual monitoring function. Background Technology
[0002] Externally coated corrugated metal oil conservators are products used for oil storage in transformers in the power industry. To ensure the reliability of these conservators, the industry standard employs a sealed cabinet made of welded steel plates, such as... Figure 1 As shown, this structure features robust welding, simple manufacturing process, and convenient operation, making it the primary structural form used by manufacturers in the industry. However, the disadvantage of this welded steel plate sealing frame is that the internal condition of the cabinet cannot be observed. Only oil level changes can be displayed via a magnetic flip panel, which cannot clearly reflect the internal state. If the magnetic flip panel indicates an abnormal liquid level, the true cause cannot be determined, necessitating the destruction of the cabinet for observation. This hinders design optimization and improvements in operating conditions.
[0003] With the continuous upgrading of industry technology and the constant changes in operating conditions, the demand for visualization inside oil conservator tanks is also increasing. By observing the oil level and expansion core inside the oil conservator tank in real time, we can better observe and record the oil injection rate, oil level changes, and the impact of various operating conditions on the inside of the oil conservator tank. We can use actual data to improve and optimize the equipment, thereby continuously ensuring the safety and stability of power equipment throughout its entire life cycle. Utility Model Content
[0004] In order to meet the need for visualization of the interior of the oil storage tank, the purpose of this utility model is to provide an external oil corrugated metal oil storage tank with visual monitoring function.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] This utility model includes a viewing window, a viewing window frame, and an outer cover. The viewing window frame is fixed to the periphery of the opening on the oil tank body. The viewing window is sealed and bonded to the viewing window frame, with the bonding position on the periphery of the opening on the oil tank body. Two layers of sealing rings, inner and outer, are provided between the viewing window and the viewing window frame, both of which are located on the periphery of the opening on the oil tank body. The outer cover is fixed to the viewing window frame.
[0007] Wherein: the inner and outer sealing rings are an outer sealing ring and an inner sealing ring, the outer sealing ring is located at the outer edge of the viewing window, and the inner sealing ring is located at the outer edge of the opening on the oil tank cabinet.
[0008] The outer edge of the outer cover is fixed to the outer edge of the viewing window frame by multiple bolts. A washer is provided at the position of each bolt between the outer cover and the viewing window frame, and the bolt passes through the washer.
[0009] An anti-vibration guide device is provided between the bottom edge of the corrugated core inside the oil storage tank and the inner wall of the oil storage tank.
[0010] The shock-absorbing and guiding device includes guide rollers and guide rails. Multiple guide rollers are installed circumferentially along the bottom edge of the corrugated core inside the oil tank. Guide rails are installed on the inner wall of the oil tank corresponding to the positions of each guide roller. The guide rollers roll up and down along the guide rails as the corrugated core expands or contracts.
[0011] The sides and bottom of the oil storage tank are equipped with remote pressure monitoring devices for real-time monitoring of pressure changes inside the tank.
[0012] The pressure remote monitoring device is a pressure sensor.
[0013] The oil storage tank has openings on one or both sides along its length, and each opening is equipped with a set of viewing windows, a viewing window frame, and an outer cover.
[0014] The advantages and positive effects of this utility model are as follows:

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.
[0023] like Figures 2-5 As shown, this utility model includes a viewing window 2, a viewing window frame 3, and an outer cover 8. The viewing window frame 3 is fixed to the periphery of the opening on the oil tank body 1. The viewing window 2 is sealed and bonded to the viewing window frame 3 with glass glue, and the bonding position is on the periphery of the opening on the oil tank body 1. There are also two layers of sealing rings, inner and outer, between the viewing window 2 and the viewing window frame 3. Both the inner and outer sealing rings are located on the periphery of the opening on the oil tank body 1. The outer cover 8 covers the outside of the viewing window 2 and is fixedly connected to the viewing window frame 3.
[0024] The oil conservator cabinet 1 has openings on one or both sides along its length. Each opening is equipped with a viewing window 2, a viewing window frame 3, and an outer cover 8. In this embodiment, the oil conservator cabinet 1 has symmetrical openings on both sides along its length, with a viewing window 2, a viewing window frame 3, and an outer cover 8 installed at each opening. The oil conservator cabinet 1 is made of carbon steel and is sealed by welding at the top and bottom. It is mainly used for storing transformer oil.
[0025] In this embodiment, the viewing window 2 adopts a double-layer tempered glass structure, which ensures explosion-proof and high-temperature resistance while enhancing its compressive strength and sealing rigidity. The viewing window 2 is used to observe the changes in oil volume inside the oil tank 1, allowing for a direct observation of the actual situation inside the oil tank 1, which has certain advantages compared to traditional structures.
[0026] In this embodiment, the viewing window frame 3 is made of carbon steel. A post-weld processing method is used to prevent flatness deviations caused by welding deformation. Specifically, the viewing window frame 3 is first welded to the opening on the oil tank body 1, and then the surface is milled. The viewing window frame 3 in this embodiment is a square frame, and the inner ring dimension of the viewing window frame 3 is larger than the opening dimension of the oil tank body 1. The viewing window frame 3 adopts a segmented protective sealing method to prevent the viewing window 2 from cracking or leaking oil. Specifically, the outer edge of the outer cover 8 is fixed to the outer edge of the viewing window frame 3 by multiple bolts, clamping the viewing window 2 in the middle. A washer is provided between the outer cover 8 and the viewing window frame 3 at the position corresponding to each bolt, and the bolt passes through the washer.
[0027] In this embodiment, the two sealing rings are an outer sealing ring 4 and an inner sealing ring 7. The outer sealing ring 4 is located at the outer edge of the viewing window 2, and the inner sealing ring 7 is located at the outer edge of the opening on the oil tank body 1. Both the outer sealing ring 4 and the inner sealing ring 7 are non-metallic (nitrile rubber) sealing rings. The sealing in this embodiment adopts a double sealing method of sealing rings and glass glue to ensure that there is no leakage under positive pressure inside the oil tank body 1.
[0028] In this embodiment, a shock-absorbing guide device is provided between the bottom edge of the corrugated core 10 inside the oil storage tank 1 and the inner wall of the oil storage tank 1. The shock-absorbing guide device includes guide rollers 5 and guide rails 9. Multiple guide rollers 5 are installed circumferentially along the bottom edge of the corrugated core 10 inside the oil storage tank 1. Guide rails 9 are installed on the inner wall of the oil storage tank 1 corresponding to the positions of each guide roller 5. The guide rollers 5 roll up and down along the guide rails 9 as the corrugated core 10 expands or contracts, using a rolling mode to avoid the impact of vibration on the oil storage tank. The shock-absorbing guide device can effectively solve the vibration problem in the actual working conditions of offshore platforms and prevent combined displacement from affecting the service life of the oil storage tank.
[0029] In this embodiment, pressure remote monitoring devices 6 are installed on the sides and bottom of the oil tank 1 to remotely monitor the pressure changes inside the oil tank 1 in real time. The purpose of real-time intelligent remote monitoring is to ensure stable operation monitoring of the oil tank throughout its service life. Two devices are installed on the sides and four are installed on the bottom. In this embodiment, the pressure remote monitoring device 6 is a pressure sensor.
[0030] This utility model, by setting a viewing window 2 and a viewing window frame 3 on the oil tank body 1, achieves the purpose of real-time observation of the oil level and corrugated core 10 inside the oil tank body 1. It can better observe and record the oil injection rate, oil level changes, and the impact of various operating conditions on the inside of the oil tank body 1, and use actual data to improve and optimize the equipment, thereby continuously ensuring the safety and stability of the power equipment throughout its entire life cycle.
