Problems solved by technology

Most of the large oil tanks in China are often composed of multiple circles of unequal thickness wall plates, which are placed on the elastic base in a non-anchored manner. Due to the large diameter of the foundation of the large oil tank, the foundation of the oil tank will inevitably break down after a long period of use. H Tr
Various settlements will lead to deformation of the storage tank body. The deformation of the storage tank will not only cause the floating roof to get stuck and cannot move up and down, which will reduce the storage capacity of the storage tank. tearing occurs, resulting in leakage

specific Embodiment 1

[0037] Such as figure 1 , 2As shown, the large oil storage tank deformation monitoring and deviation correction device and method of the present invention,

[0038] The invention discloses a deformation monitoring and deviation correction device for a large oil storage tank, which includes a deformation monitoring device, a deviation correction device, and a controller;

[0039] The storage tank body 1 is arranged on the base 2;

[0040] The deformation monitoring device includes a track body 8, a scanner 3, and a stress monitoring device 6; the track body 8 is erected horizontally around the storage tank body 1, and the track body 8 is connected to the base 2 through a telescopic track pillar 7; the track body 8 It consists of 3-6 independent track pieces spliced ​​into a complete ring. Adjacent track pieces are connected end to end, and there is no fixed connection at the junction. There is a gap of 3-5mm at the joint, and the adjacent track pieces are staggered. When thi...

Embodiment 2

[0046] The monitoring method of the deformation monitoring device in embodiment 2 is:

[0047] Step 1: When the base 2 settles, a shift occurs between adjacent track pieces and pressure is applied to the stress monitoring device 6, and the pressure sensor in the stress monitoring device 6 monitors the pressure data and sends it to the controller;

[0048] Step 2: After the controller receives the pressure data, according to the pressure data and the stress monitoring device 6, control the lifting of the corresponding track pillar 7 and adjust the adjacent track pieces to be in a horizontal state;

[0049] Step 3: The scanner 3 moves along the track and scans the storage tank, and collects the shape data of the storage tank. After the collected shape data is transmitted to the controller, the controller builds a three-dimensional model based on the data collected by the scanner 3, and stores the shape data of the tank. The 3D model is stored as the original model.

[0050] Ste...

specific Embodiment 3

[0053] Based on the device of embodiment 1 and the method of 2, the deviation correction method of this deviation correction device is:

[0054] Step 1: When the storage tank body 1 is deflected, the controller obtains the deflection data of the storage tank body 1 and calculates the position and adjustment amount of the corresponding deviation correction device;

[0055] Step 2: According to the order of the adjustment amount from small to large, the controller sequentially controls the unlocking of the positioning lock of the corresponding deviation correction device, and then controls the expansion and contraction of the retractor 4 to adjust the length of the deviation correction rope 5;

[0056] Step 3: When the stretching amount of the stretcher 4 reaches the adjustment amount calculated by the controller, the positioning lock re-locks the deviation correction device;

[0057] Step 4: When the corresponding deviation correcting devices are adjusted, complete the deviatio...

Abstract

The invention relates to a large-sized oil storage tank deformation monitoring and deviation correcting device and method and belongs to the oil storage tank monitoring and deviation correcting field. The device comprises a deformation monitoring device, a deviation correcting device and a controller; a tank body is arranged on a base; the deformation monitoring device includes a track body, a scanner and a stress monitoring device; the deviation correcting device includes a deviation correcting rope, an expansion joint and a positioning lock; and the controller is electrically connected with the deformation monitoring device and the deviation correcting device. As for the real-time monitoring device which is developed for a large-sized oil storage tank of which the capacity is 50000 cubic meters or above, the large-sized oil storage tank has high requirements for the base since the weight of the large-sized oil storage tank is large, when the base subsides, the center of gravity of the oil storage tank will deviate, and as a result, the oil storage tank will be deformed, and therefore, requirements for the base is high, and thus, with the device adopted, uniform stress of the base can be ensured, and the deformation and fracture of the oil storage tank caused by excessively high pressure intensity of the base can be avoided, and the safety of the oil storage tank can be ensured.

Description

technical field [0001] The invention relates to a large oil storage tank deformation monitoring and deviation correction device and method, belonging to the field of oil storage tank monitoring and deviation correction. Background technique [0002] Oil resources are regarded as a strategic resource in the future development of the country, so it is necessary to ensure the normal storage and transportation of oil resources. With the development and maturity of oil drilling and production technology, the mining environment ranges from land, desert to deep sea, which requires oil resources to be able to be stored normally for a long time. At present, due to the development needs of the national oil strategy, the number and volume of oil tanks are also developing rapidly, with large oil tanks of 50,000 cubic meters and above being the most common. However, the larger the volume of large oil tanks, the greater the risk factor. Most of the large oil tanks in China are often com...
