Technical Field

[0001] This utility model relates to the field of safety monitoring technology for oil storage tanks, and in particular to a device for detecting foundation settlement of oil storage tanks. Background Technology

[0002] In the petroleum industry, oil storage tanks are critical facilities for storing oil, and their safety is paramount. Foundation settlement is one of the important factors affecting the safe operation of oil storage tanks. Because storage tanks are usually huge in size and bear a large weight, even minor foundation settlement is difficult to observe with the naked eye during routine inspections and maintenance. It is only discovered when the settlement accumulates to a certain extent and a functional failure occurs. However, by then the settlement is irreversible, and in severe cases, it can lead to major accidents such as floating roof tilting and tank overturning.

[0003] Currently, existing settlement detection equipment on the market has many shortcomings:

[0004] Some of the equipment has a complex structure, high installation and maintenance costs, requires professional technicians to operate, and some equipment has limited detection accuracy, making it difficult to accurately capture subtle settlement changes in the foundation.

[0005] Some equipment is significantly affected by environmental factors and cannot operate stably in harsh environments (such as high temperature, humidity, sandstorms, etc.). In addition, most existing detection equipment cannot achieve real-time, continuous monitoring and cannot provide accurate settlement data to staff in a timely manner, making it difficult to meet the high requirements for safety monitoring of oil storage tanks.

[0027] Reference Figure 1-4 This utility model provides an oil storage tank foundation settlement detection device, which includes an oil storage tank 1, a base 3, a liquid storage cylinder structure 4, a support structure 5, and a float scale structure 7 to achieve the above-mentioned objectives.

[0028] Oil storage tank 1 is installed above base 3. A fixing ring 2 is installed on the outer surface of oil storage tank 1. Float scale structure 7 is installed on the outer surface of oil storage tank 1 through fixing ring 2. Support structure 5 is installed on the side of oil storage tank 1. Liquid storage cylinder structure 4 is installed in the groove above support structure 5. Liquid storage cylinder structure 4 and float scale structure 7 are connected by a connecting pipe 6, which is a transparent flexible tube structure.

[0029] The above structure connects the liquid storage cylinder structure 4 and the float scale structure 7 through the connecting pipe 6, and uses the principle of communicating vessels to keep the liquid level of the liquid storage cylinder 403 and the transparent sleeve 701 at the same level.

[0030] The liquid storage cylinder structure 4 consists of a sealing cap 401, a water inlet 402, and a liquid storage cylinder 403.

[0031] The liquid storage cylinder 403 has a cylindrical structure and is made of corrosion-resistant plastic. The liquid storage cylinder 403 is filled with clean water and antifreeze. A sealing cap 401 is installed on the upper surface of the liquid storage cylinder 403. A water inlet 402 is opened on the upper surface of the sealing cap 401, and the sealing cap 401 is set above the water inlet 402.

[0032] The support structure 5 consists of a support base 501, a telescopic bracket 502, an anti-slip pad 503, and a fixing nail 504.

[0033] The upper surface of the support base 501 is provided with a groove, the bottom end of the support base 501 is provided with a through hole, and three telescopic brackets 502 are fixedly connected to the bottom of the support base 501. Anti-slip pads 503 are fixedly connected to the bottom end of the telescopic brackets 502. The bottom end of the anti-slip pads 503 is provided with a threaded hole, and the upper surface of the fixing nail 504 is threaded.

[0034] In the above structure, the height of the support structure 5 can be adjusted by the telescopic support 502, and the anti-slip foot pads 503 and fixing nails 504 can make the support structure 5 stable on different ground surfaces, ensuring the stability of the liquid storage cylinder structure 4, and thus ensuring the continuity and accuracy of the testing work.

[0035] The float scale structure 7 consists of a transparent sleeve 701, a guide groove 702, a scale 703, a graduation mark 704, a float 705, a guide strip 706, a connecting rod 707, and an indicator plate 708.

[0036] The inner wall of the transparent sleeve 701 is provided with three axial guide grooves 702, and the outer surface of the transparent sleeve 701 is provided with a scale 703, and the outer surface of the scale 703 is engraved with graduation marks 704.

[0037] The float 705 is placed inside the transparent sleeve 701. Three axial guide bars 706 are provided on the outer surface of the float 705. The guide bars 706 are adapted to the guide groove 702. A connecting rod 707 is fixedly connected to the top of the float 705.

[0038] In the above structure, the guide strip 706 on the outer surface of the float 705 is adapted to the guide groove 702 on the inner wall of the transparent sleeve 701, which can effectively prevent the float 705 from rotating inside the transparent sleeve 701, ensuring the accuracy of the indicator 708 and further improving the reliability of the detection data.

[0039] Working Principle: When the foundation of oil storage tank 1 settles, oil storage tank 1 will descend along with the base 3, causing the transparent sleeve 701 of the float scale structure 7 to descend synchronously via the fixing ring 2. Since the liquid storage cylinder 403 is fixed to the ground by the support structure 5 and its position remains unchanged, a height difference will be generated between the liquid storage cylinder 403 and the transparent sleeve 701. Under the principle of communicating vessels, the liquid level in the transparent sleeve 701 will rise, and the float 705 will rise with the liquid level under the action of buoyancy, causing the indicator 708 to move upward via the connecting rod 707. The change in the scale mark 704 pointed to by the apex of the indicator 708 on the scale 703 is the amount of settlement of oil storage tank 1.

[0040] When the foundation of the oil storage tank 1 bulges, the transparent sleeve 701 will rise along with the oil storage tank 1, the liquid level inside the transparent sleeve 701 will drop, the float 705 will drop with the liquid level, causing the indicator 708 to move downwards, and the amount of change in the scale mark 704 pointed to by the apex of the indicator 708 is the amount of bulge.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
