Description

Technical Field

[0001] The present invention relates to the field of cold insulation material tooling, and particularly to an automatic surveying and mapping device for measuring the arc dimensions of a storage tank. Background Art

[0002] It is predicted that without large-scale wars, before 2035, the consumption demand for natural gas in China will continue to grow rapidly, with an average annual growth rate of more than 5%. It will reach 400 billion cubic meters in 2025 and more than 600 billion cubic meters in 2035. With the rapid growth of the production and consumption of liquefied natural gas (LNG for short), high demands are put forward for storage and transportation. The cold insulation performance of its storage tank is an important factor affecting the safety, reliability and cost of LNG storage and transportation.

[0003] Inorganic solid gas cryogenic cold insulation adiabatic material (aerogel) is a new type of adiabatic material composed of nano-scale inorganic solid aerogel particles and three-dimensional inorganic fiber blankets. With the same heat preservation requirements, the thickness can be reduced by 1 / 3 - 1 / 2, and it is non-combustible and water-repellent. It is currently the adiabatic material with the best adiabatic performance in engineering applications worldwide.

[0004] In the current storage tank heat preservation measures, it is difficult to make the materials fit tightly without air leakage, which reduces the transportation efficiency and easily causes huge losses. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned defects existing in the prior art and provide an automatic surveying and mapping device for measuring the arc dimensions of a storage tank, which is convenient for preparing a cold insulation adiabatic material that fits tightly without air leakage, meets the ultra-high cold insulation requirements, has high efficiency, and reduces unnecessary losses.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] The designer knows that only when the heat preservation material fits as completely as possible with the corresponding outer wall of the storage tank, the heat preservation effect will be excellent. However, after years of exposure to wind and rain, the outer wall of the storage tank no longer corresponds to the original design dimensions. At this time, the most accurate parameters of each storage tank outer wall must be measured to facilitate the preparation of materials with heat preservation pertinence. Therefore, the following specific solutions are proposed:

[0008] An automatic surveying and mapping device for measuring the arc dimensions of a storage tank, the device includes:

[0009] An induction universal ball, used to identify the arc dimensions of the storage tank;

[0010] A control box, used to record the data of the arc dimensions of the storage tank identified by the induction universal ball;

[0011] The control box is connected to the induction universal ball through a hydraulic pipeline induction line. The control box is fixedly arranged on a movable support mechanism. During measurement, the induction universal ball abuts against the outer wall of the storage tank.

[0012] The external structure of the hydraulic pipeline induction line is similar to a bendable tube of a mobile phone holder. It can be bent and also maintains a certain rigidity. The internal part houses a signal line to ensure that the data recognized by the induction universal ball can be transmitted to the control box.

[0013] After the induction universal ball has explored the entire outer wall of the storage tank, the arc dimensions at each location on the outer wall of the storage tank are recognized and recorded. After data processing by the control box, the outer wall of the storage tank can be automatically mapped and shaped, and displayed by a certain output device, providing relatively complete and accurate guiding parameters for the production shape of the insulation material of the tank.

[0014] Further, the induction universal ball is provided with induction points for identifying the arc dimensions of the storage tank. During measurement, the induction points abut against the outer wall of the storage tank.

[0015] The induction points are generally pressure sensors.

[0016] Further, the number of the induction universal balls is not less than 4, and adjacent induction universal balls are hinged through a linkage shaft; the induction universal ball is hinged with the linkage shaft.

[0017] In order to improve the measurement efficiency and avoid chaotic measurement, multiple induction universal balls can be connected into a polygon, and the instability of the polygon is cleverly utilized to keep the positions of the induction universal balls still have a certain degree of flexibility. Using the surface instead of points, the measurement efficiency is better and the data is more accurate.

[0018] Further, the number of induction points on each induction universal ball is not less than six.

[0019] In this way, no matter what the relative position relationship of each induction universal ball is, it can be ensured that there are induction points abutting against the outer wall of the storage tank.

[0020] Further, the device further includes a display screen for displaying the arc dimension data, and the display screen is electrically connected to the control box.

[0021] Further, the outside of the hydraulic pipeline induction line is a bendable tubular structure, and the inside of the tubular structure includes a data transmission line.

[0022] Further, the support mechanism includes a liftable bracket and a support base below the bracket.

[0023] Further, the control box is fixedly arranged on the side part above the bracket.

[0024] Further, the display screen is arranged on the top of the bracket.

[0025] Furthermore, the material of the inductive universal ball is metal stainless steel.

[0026] Furthermore, the universal ball can turn in different directions.

[0027] Furthermore, the maximum angle between the linkage shafts is 180°.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] (1) In the present invention, the arc distance of different arc surfaces can be measured by the free rotation of the universal ball in different directions, without the need for on-site manual measurement and processing, thus saving construction costs, and the obtained data is more accurate, avoiding huge economic losses, and there is no need to specifically produce an inorganic solid gas cryogenic insulation material device with a specific shape to fit the size and structure of the storage tank, greatly reducing the production cost; at the same time, the device of the present invention can also be applied to other insulation projects, with a wide range of applications;

[0030] (2) In the present invention, there are no less than four universal balls, and each one is connected to the control box by a hydraulic pipeline induction line, which is flexible and light to use and simple to operate; and there are at least six induction points on each universal ball, which can not only ensure that accurate measurement results are obtained when the universal ball contacts the cross-section to be measured, but these induction points also have the function of fixing the size of the subsequent engineering plastics. In the modular production and manufacturing process of the entire cryogenic insulation product, it is one of the crucial devices;

[0031] (3) In the present invention, the control box not only records the data measured by the universal ball at present, but also has the function of storing data. After all the surveying and mapping work is completed, the module production of the cryogenic insulation material can be carried out through the archived data. According to the accurate size, the modules obtained can fit better, which is convenient for more firm pasting and coating, and finally achieves a significant storage tank insulation effect;

[0032] (4) In the present invention, the universal ball is made of metal stainless steel. The materials required for the device are not only easy to purchase in the market, but also have a low cost and can meet the requirements, with a high cost performance; the control box is installed on the side of the bracket. Compared with the traditional floor-mounted design method, the device is lighter and does not occupy much area, and it is an environmentally friendly product. BRIEF DESCRIPTION OF THE DRAWINGS

During measurement, the induction universal ball 1 abuts against the outer wall of the storage tank. The device further includes a display screen 6 for displaying the arc size data, and the display screen 6 is electrically connected to the control box 5. The support mechanism includes a liftable bracket 7 and a support base 8 below the bracket 7. The control box 5 is fixedly arranged on the upper side of the bracket 7. The display screen 6 is arranged on the top of the bracket 7.

[0038] The induction universal ball 1 is provided with induction points 2 for identifying the arc size of the storage tank. During measurement, the induction points 2 abut against the outer wall of the storage tank. The induction points 2 are generally pressure sensors. The number of induction universal balls 1 is 4, and adjacent induction universal balls 1 are hinged through a linkage shaft 3, similar to the connection method between the pole of a mop and the mop head; the induction universal ball 1 is hinged to the linkage shaft 3. The number of induction points 2 on each induction universal ball 1 is six. The material of the induction universal ball 1 is metal stainless steel.

[0039] The external structure of the hydraulic pipeline induction wire 4 is similar to a bendable tube of a mobile phone holder, which can be bent and also maintains a certain rigidity. The signal wire is hidden inside to ensure that the data identified by the induction universal ball 1 can be transmitted to the control box 5.

[0040] During use, the device is pushed to the arc surface, tank body, saddle, and front of the top inlet and outlet gas pipes of the target LNG storage tank, so that the induction universal ball 1 is aligned and attached to each surface. The induction universal ball 1 rotates freely to capture the arc sizes of each part. After the induction universal ball 1 has explored the entire outer wall of the storage tank, the arc size of each part of the outer wall of the storage tank is identified and recorded.
