Description

Technical Field

[0001] This utility model belongs to the field of storage tank testing technology, and relates to a device for measuring the plumbness and settlement of storage tanks. Background Technology

[0002] Storage tanks, as key equipment in industries such as petroleum, chemical, and food processing, are widely used for the storage and transportation of various liquids and gases. During long-term operation, storage tanks may experience structural deformation or displacement due to various factors, with uneven foundation settlement and tank deformation being the most common causes. Foundation settlement is usually caused by insufficient soil bearing capacity, changes in groundwater levels, or external loads, while tank deformation may stem from material fatigue, temperature stress, or fluctuations in operating pressure. These changes can cause the verticality of the storage tank to exceed allowable limits, accompanied by uneven settlement, severely impacting the structural integrity and safety of the tank.

[0003] Excessive vertical deviation can lead to uneven liquid distribution within the storage tank, increasing localized stress and accelerating the risk of tank corrosion or weld cracking. Severe settlement can cause leaks at pipe connections and even trigger major accidents such as tank overturning. Therefore, regular and accurate measurement and monitoring of the verticality and settlement of storage tanks is crucial. Common monitoring methods include total stations, levels, and laser scanning. Combined with automated monitoring systems, real-time data acquisition and analysis can be achieved, enabling timely detection of potential risks. By scientifically evaluating the measurement results, companies can develop targeted maintenance or reinforcement plans to ensure the long-term stable operation of the storage tanks, avoiding production interruptions, environmental pollution, or safety accidents caused by structural failure, thereby protecting personnel safety and economic benefits.

[0004] Currently, common methods for measuring the plumbness and settlement of storage tanks include total station measurement and level measurement. However, these methods have obvious drawbacks: they require operation by professionals, the measurement process is complex, resulting in low efficiency and difficulty in achieving real-time monitoring.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0025] like Figure 1 - Figure 5 As shown, a device for measuring the plumbness and settlement of a storage tank includes a mounting base a101, a mounting base b102 at the lower end of the mounting base a101, a mounting base c103 at the lower end of the mounting base b102, an angle detection mechanism between the mounting base a101 and the mounting base b102, and a settlement detection mechanism between the mounting base b102 and the mounting base c103.

[0026] The angle detection mechanism includes a fixed rod 104. The fixed rod 104 is fixedly connected to the middle of the lower end of the mounting base a101. The lower end of the fixed rod 104 is fixedly connected to a fixed ball 105. A conical metal block 106 is rotatably connected to the outer side of the fixed ball 105. A laser emitting lamp 107 is fixedly connected to the lower end of the conical metal block 106. A signal receiver a108 is provided on the inner side of the upper end of the mounting base b102.

[0027] Workers installed mounting bracket a101 and mounting bracket b102 on the outside of the storage tank.

[0028] A sealing barrel 201 is provided between the mounting base a101 and the mounting base b102, and the upper and lower ends of the sealing barrel 201 are fixedly connected to the mounting base a101 and the mounting base b102 respectively.

[0029] The sealing barrel 201 keeps the mounting base a101 and mounting base b102 in a sealed state, thereby preventing air from blowing the conical metal block 106 and causing it to shake.

[0030] During operation, the staff installs mounting base a101 and mounting base b102 on the outside of the storage tank. After installation, the laser emitting lamp 107 is activated, and the laser is emitted through the laser emitting lamp 107. The signal is received and fed back through the signal receiver a108, thereby determining the initial reference position of the laser emitting lamp 107 and feeding back the initial reference position of the laser emitting lamp 107 to the terminal.

[0031] As the conical metal block 106 causes the laser emitting lamp 107 to hang down naturally, when the storage tank tilts, the conical metal block 106 causes the laser emitting lamp 107 to rotate outside the fixed ball 105.

[0032] At this time, the storage tank causes the mounting base b102 and mounting base a101 to tilt together, and the conical metal block 106 causes the laser emitting lamp 107 to hang down naturally. As a result, the position of the laser emitted by the laser emitting lamp 107 on the signal receiver a108 changes. After receiving the signal feedback, the signal receiver a108 feeds the information back to the terminal. The terminal makes a judgment after receiving the signal. After detecting that the initial reference position has changed, it then issues an alarm. Example

[0033] like Figure 3 - Figure 5As shown, the sinking detection mechanism includes a support frame 301. The upper end of the mounting base c103 is fixedly connected to the support frame 301. A metal tube 302 is fixedly connected to the inner side of the support frame 301. A conversion tube 303 is fixedly connected to the end of the metal tube 302. A support tube 304 is fixedly connected to the upper end of the conversion tube 303. A signal receiver b305 and an illumination lamp 306 are symmetrically installed on the inner side of the support tube 304. A flexible hose assembly is provided between the metal tube 302 and the mounting base b102.

[0034] The hose assembly includes a fixed tube 403, the end of the metal tube 302 away from the conversion tube 303 is fixedly connected to the fixed tube 403, the end of the fixed tube 403 away from the metal tube 302 is fixedly connected to the folded tube 402, and the upper end of the folded tube 402 is fixedly connected to the connecting tube 401.

[0035] When the storage tank tilts, the distance between the extension connecting pipe 401 and the folding pipe 402 is adjusted accordingly.

[0036] A connecting rod 501 is fixedly connected to the lower end of the middle part of the mounting base b102, and the connecting tube 401 is sleeved on the outside of the connecting rod 501;

[0037] The connecting rod 501 enables workers to install the device in a modular fashion.

[0038] Multiple sets of mounting holes 601 are provided on the inner side of the mounting base c103;

[0039] The mounting base c103 is installed on the foundation surface outside the storage tank by passing expansion bolts through mounting holes 601.

[0040] During operation, the expansion bolts are passed through the mounting hole 601, and the mounting base c103 is installed on the foundation surface outside the storage tank. Then, the barrier liquid is injected into the inside of the connecting pipe 401 until the liquid level reaches the set height. After the barrier liquid is injected, the connecting pipe 401 is sleeved on the outside of the connecting rod 501. Then, the illumination lamp 306 is turned on so that the illumination lamp 306 shines light on the signal receiver b305.

[0041] Based on the principle of communicating vessels, the barrier liquid inside the support tube 304 is made to be at the same height as the barrier liquid inside the connecting tube 401, thereby blocking the light from the illumination lamp 306 through the barrier liquid. This causes the signal receiver b305 to be unable to receive the light signal from the blocked area, while the light from the unblocked part can still be received. Thus, the signal receiver b305 feeds back the area of ​​light received to the terminal, and the terminal records this position as the initial reference position.

[0042] When the storage tank sinks, it will cause the mounting base b102 and the connecting rod 501 to sink together, thereby shortening the distance between the mounting base b102 and the mounting base c103. This causes the barrier liquid inside the support pipe 304 to rise and block the light from the illumination lamp 306, thus changing the signal received by the signal receiver b305. The receiver then feeds the information back to the terminal. After receiving the signal, the terminal makes a judgment and, upon detecting a change in the initial reference position, issues an alarm.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
