Description

TECHNICAL FIELD

[0001] The utility model relates to transformer oil storage mechanism field, concretely relates to a hoop clamping sealed oil storage tank. BACKGROUND

[0002] The main functions of the transformer oil storage tank include ensuring that the oil tank is always full of oil, reducing the contact area of the oil and air, adjusting the oil volume, and creating conditions for installing gas relays. These functions together ensure the stable operation of the transformer and prolong its service life.

[0003] The traditional oil storage tank is a certain length of round tank wall, one end of which is welded with a 6-8mm flange, and the flange and the circular tank cover are clamped and sealed with multiple bolts, and a sealing pad is placed between the cover and the flange to ensure that the transformer oil in the tank does not leak.

[0004] The common flange is a ring-shaped steel plate ring. After the whole steel plate is cut, the material in the middle of the inner circle is treated as waste, which is a serious waste. At the same time, the flange and the tank wall need to be welded together, which wastes labor and welding rods. The tank cover and the flange are pressed tightly with multiple bolts, which wastes bolts and labor. And there are hidden dangers such as slag inclusion, incomplete welding, false welding, bubbles, pinholes and other hidden dangers at the welding position, which causes oil leakage. INVENTION CONTENTS

[0005] The utility model aims to provide a hoop clamping sealed oil storage tank to solve the above problems existing in the prior art.

[0006] Technical scheme: A hoop clamping sealed oil storage tank, comprising a tank wall and a tank cover; the tank wall is hollow and has a predetermined accommodation, and is connected to the tank cover through a hoop.

[0007] In further embodiments, one end of the tank wall near the tank cover is provided with an adapter end with a predetermined bending radius, and one end of the tank cover near the tank wall is provided with a connecting end with a predetermined bending radius; the adapter end and the connecting end are connected through a sealing pad.

[0008] In further embodiments, the hoop is wrapped around the adapter end and the connecting end, has a predetermined bending radius and flexibility, and can be adjusted within a predetermined range.

[0009] In further embodiments, the tank cover is provided with an oil gauge at a predetermined working position on the working surface, and the hoop is limited by a bolt.

[0010] Beneficial effects: the utility model relates to a clamp tight sealing type oil storage tank of hoop, relate to transformer oil storage mechanism field, including cabinet wall and cabinet cover, the cabinet wall is hollow and has predetermined accommodation, and with cabinet cover is linked through hoop, the utility model discloses the combination of cylindrical cabinet wall and cabinet cover, through rolling forming, form the anastomosis, the anastomosis is padded with sealing pad, through the rolling recess section hoop tight, to reach the sealing purpose. Can save 8 millimeter flange, save material, save blanking time. At the same time, avoid welding process, avoid flange and cover drilling process, save welding material and also save the corresponding working hours. And the bolt is reduced to one from ten to twenty three, reduce material waste, save assembly time due to cabinet cover pressure groove processing, increase mechanical strength, cabinet cover is reduced to 2 millimeter from 6 millimeter, reduce material waste. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 It is the overall schematic diagram of the present application.

[0012] Figure 2 It is the overall schematic diagram of prior art.

[0013] Figure 3 It is the schematic diagram of the hoop.

[0014] The reference signs in the drawings are: cabinet wall 1, hoop 2, sealing pad 3, cabinet cover 4, oil gauge 5, flange 6, bolt 7. DETAILED DESCRIPTION

[0015] In the following description, a large number of specific details are given to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, some technical features known in the art are not described in order not to obscure the present application.

[0016] The hoop 2 clamp tight sealing type oil storage tank of the embodiment includes cabinet wall 1 and cabinet cover 4; the cabinet wall 1 is hollow and has predetermined accommodation, and is communicated with the cabinet cover 4 through the hoop 2. The end of the cabinet wall 1 close to the cabinet cover 4 is provided with an adapter end with a predetermined bending radius, and the end of the cabinet cover 4 close to the cabinet wall 1 is provided with a connecting end with a predetermined bending radius; the adapter end and the connecting end are communicated through the sealing pad 3. The hoop 2 is wrapped outside the adapter end and the connecting end, has a predetermined bending radius and toughness, and can be adjusted within a predetermined range. The oil gauge 5 is arranged at a predetermined working position on the working surface of the cabinet cover 4, and the hoop 2 is limited by the bolt 7.

[0017] In a further preferred embodiment, the cabinet wall 1 and the cabinet cover 4 are roll-formed, i.e. the joint end and the connecting end are both roll-formed, and the bending radius of the joint end and the bending radius of the connecting end are matched to form a corresponding anastomosis. The sealing gasket 3 is placed in the anastomosis formed by the joint end and the connecting end, the clamp 2 is tightened by rolling, and finally limited and fixed by the bolt 7 to achieve the sealing purpose. Since the sealing is achieved by roll-forming, the sealing performance is ensured, and hidden problems such as slag inclusion, incomplete welding, false welding, bubbles, pinholes and the like at the welding position are avoided, thereby preventing oil leakage.

[0018] As described above, although the utility model has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation on the utility model itself. Various changes can be made to the form and details thereof without departing from the spirit and scope of the utility model defined in the appended claims.
