[0003] Existing corrosion inhibitor storage devices require cleaning of their inner walls when storing different types of corrosion inhibitors. However, the bottom and inner walls near the bottom of existing storage tanks are difficult to access, making cleaning very difficult. In addition, some corrosion inhibitors (such as liquid zinc salt inorganic corrosion inhibitors) will precipitate after long-term storage, accumulating and hardening into slag at the bottom, making it even more difficult to clean them when they are hard to access.

[0019] The following is combined with Figures 1 to 3 This utility model will be described in detail.
[0020] An oilfield corrosion inhibitor storage device includes a tank 1, an inner wall of which is provided with a deflection groove 103, and connecting grooves 101 are provided on both sides of the inner wall of the deflection groove 103. A bottom plate 2 is connected to the bottom of the tank 1, and connecting shafts 203 are provided on both sides of the bottom plate 2. The connecting shafts 203 cooperate with the connecting grooves 101. A support ring 102 is provided at the bottom of the inner wall of the tank 1, and a handle 201 is provided at the bottom of the bottom plate 2.
[0021] Furthermore, the connecting groove 101 is an elongated groove on both sides of the deflection groove 103, and the width of the connecting groove 101 matches the diameter of the connecting shaft 203. The support ring 102 is a circular protrusion on the bottom of the inner wall of the tank 1, and the diameter of the support ring 102 is smaller than the diameter of the bottom plate 2. The support ring 102 also includes a fitting ring groove 1021, a sealing ring 1022, and a limiting block 1023. The fitting ring groove 1021 is located at the top of the support ring 102, the sealing ring 1022 is located on one side of the middle of the fitting ring groove 1021, and the limiting block 1023 is connected to the middle of the fitting ring groove 1021 away from the sealing ring 203. On one side of the sealing ring 1022, one end of the limiting block 1023 is spherically shaped, and one end of the limiting block 1023 is connected to the groove on one side of the middle of the fitting ring groove 1021 by a spring. The base plate 2 also includes a fitting ring 202 and a limiting groove 2021. The fitting ring 202 is located at the bottom of the base plate 2, and the limiting groove 2021 is located on one side of the fitting ring 202. The limiting groove 2021 is in spherical fit with one end of the limiting block 1023. The fitting ring 202 is a protrusion on the bottom of the base plate 2 that fits with the fitting ring groove 1021. The top edge of the base plate 2 and the bottom edge of the fitting ring 202 are arc-shaped.
[0022] First, the corrosion inhibitor is poured into the tank 1, and the top cover is closed for storage. When the corrosion inhibitor is used up and the tank 1 needs to be filled with a different type of corrosion inhibitor, the inner wall of the tank 1 needs to be cleaned. When the surface of the bottom plate 2 needs to be cleaned, the tank 1 is first laid horizontally, exposing the bottom plate 2. Then, by applying force through the control handle 201, the fitting ring 202 at the bottom of the bottom plate 2 is separated from the fitting ring groove 1021 at the top of the support ring 102. Then, the bottom plate 2 moves along the connecting slide 101 via the connecting shaft 203, thereby separating it from the support ring 102 by a certain distance. Then, the connecting shaft 203 rotates in the connecting slide 101 to clean the entire bottom plate 2. The bottom plate 2 is deflected and flipped so that its top faces outward for easy cleaning. When the bottom plate 2 moves to the top of the connecting chute 101 and flips, it will be in the deflection groove 103. The groove of the deflection groove 103 allows the bottom plate 2 to deflect without interfering with the inner wall of the tank 1. It can also be deflected at a certain angle without flipping, so that the bottom of the tank 1 is opened and can better contact the part of the inner wall of the tank 1 near the bottom for easier cleaning. This avoids the inconvenience of cleaning because the bottom plate 2 is difficult to contact at the bottom of the tank. At the same time, the corrosion inhibitor will settle and accumulate on the surface of the bottom plate 2 after long-term storage. After the sediment hardens, it will be even more difficult to clean under inconvenient contact conditions.
[0023] Finally, the connection between the fitting ring 202 and the fitting ring groove 1021 is achieved by squeezing the spherical part of the limiting block 1023 to make it shrink, and then by the spring at one end, it is reset and fitted into the limiting groove 2021 for connection, so that the connection between the fitting ring 202 and the fitting ring groove 1021 will not easily separate on its own, and the sealing ring 1022 can prevent liquid leakage.
[0024] The following is a detailed implementation process of this utility model: First, the corrosion inhibitor is poured into the tank 1, and the top cover is closed for storage. When the corrosion inhibitor is used up and the tank 1 needs to be filled with a corrosion inhibitor of different composition, the inner wall of the tank 1 needs to be cleaned. When the surface of the bottom plate 2 needs to be cleaned, the tank 1 is first laid horizontally, exposing the bottom plate 2. Then, by controlling the handle 201 to apply force and push, the fitting ring 202 at the bottom of the bottom plate 2 will separate from the fitting ring groove 1021 at the top of the support ring 102. Then, the bottom plate 2 moves along the connecting slide 101 via the connecting shaft 203, thereby engaging with the support ring. 102 is separated by a certain distance, and then rotated in the connecting groove 101 through the connecting shaft 203 to deflect and flip the entire bottom plate 2, so that the top of the bottom plate 2 faces outward for easy cleaning. At the same time, it can also be deflected at a certain angle without flipping, so that the bottom of the tank 1 is opened, which can better contact the part of the inner wall of the tank 1 near the bottom for easier cleaning. This avoids the inconvenience of cleaning because the bottom plate 2 is difficult to contact at the bottom of the tank. At the same time, the corrosion inhibitor will settle and accumulate on the surface of the bottom plate 2 after long-term storage, and the hardened sludge will make it even more difficult to clean under inconvenient contact conditions.
