Description

Technical Field

[0001] This invention relates to the field of double-walled spherical tank technology, specifically to a method and system for stabilizing the inner sphere of a double-walled spherical tank. Background Technology

[0002] A double-walled spherical tank is a common container used to store liquids or gases. It consists of two spherical shells with a gap between the inner and outer layers. The inner spherical tank stores the liquid or gas, while the outer spherical tank provides protection and insulation. The design of double-walled spherical tanks primarily aims to increase the safety and stability of the stored substances. The inner spherical tank prevents leakage or external contamination, while the outer spherical tank protects the stored substances from the effects of external temperature changes. Double-walled spherical tanks are commonly used in the petroleum, chemical, and food industries to store raw materials, finished products, or waste materials. They typically possess certain explosion-proof and corrosion-resistant properties to ensure the safety and stability of the stored substances.

[0003] Current double-walled spherical tanks consist of an inner sphere, an outer sphere, and support pillars. The pillars support the outer sphere, while the inner sphere is located inside the outer sphere. The outer sphere has a support net or similar structure that is flexibly connected to the inner sphere. Due to this flexible connection, the relative positions of the inner and outer spheres can change when subjected to strong external forces such as typhoons, affecting the stability of the double-walled spherical tank. Summary of the Invention

[0004] In view of the above problems, embodiments of the present invention provide a method and system for stabilizing the inner sphere of a double-layered spherical tank, which solves the problem that in the prior art, the inner sphere is easily affected by the external environment and its position changes, thus affecting the stability of the double-layered spherical tank when the inner and outer spheres are connected by a soft connection.

[0005] According to one aspect of the present invention, a method for stabilizing the inner sphere of a double-layered spherical tank is provided, the method comprising:

[0006] Receive information on the fixed position of the inner ball;

[0007] Generate information on the connection status adjustment between the inner and outer balls based on the fixed position information of the inner ball;

[0008] Adjust the inner and outer ball connection device according to the connection status information of the inner and outer balls, and fix the inner ball on the outer ball.

[0009] In one alternative approach, adjusting the inner and outer sphere connection device according to the inner and outer sphere connection status adjustment information to fix the inner sphere onto the outer sphere specifically includes: controlling an air bladder set on the inner wall of the outer sphere in the inner and outer sphere connection device according to the inner and outer sphere connection status adjustment information, so that the air bladder expands and contacts the inner sphere to limit and fix the inner sphere.

[0010] In one alternative approach, the method further includes acquiring the tilt angle of the inner sphere, generating inner sphere position adjustment information based on the tilt angle of the inner sphere, and then controlling the airbags located at different positions on the inner wall of the outer sphere in the inner and outer sphere connection device to simultaneously inflate and deflate based on the inner sphere control adjustment information, thereby adjusting the position of the inner sphere.

[0011] In one alternative approach, the number of inflatable airbags is greater than the number of deflated airbags.

[0012] In one alternative approach, after adjusting the inner and outer ball connection device according to the inner and outer ball connection status adjustment information and fixing the inner ball onto the outer ball, the method further includes: obtaining the maximum angle difference of the inner ball tilt angle within a preset time, and comparing the maximum angle difference with a preset angle difference; if the maximum angle difference is greater than the preset angle difference, then generating airbag maintenance information.

[0013] In one alternative embodiment, the inner and outer sphere connecting device includes: a support ring, a support rib, an annular reinforcing ring, an airbag, and an air pump for controlling the airbag. The annular reinforcing ring is installed at the equator of the outer sphere. The support ring is fixedly connected to the annular reinforcing ring via the support rib. The support ring and support rib are used to place the inner sphere. The airbag is disposed on the inner wall of the outer sphere. After the airbag is inflated, it can contact the outer wall of the inner sphere.

[0014] In one alternative embodiment, the bottom of the outer sphere is provided with a maintenance cover, which is detachably connected to the outer sphere shell.

[0015] According to another aspect of the present invention, an inner sphere stabilization system for a double-walled spherical tank is provided, comprising:

[0016] The receiving module is used to receive information about the fixed position of the inner ball;

[0017] The processing module is used to generate information for adjusting the connection status between the inner and outer balls based on the fixed position information of the inner ball;

[0018] The adjustment module is used to adjust the inner and outer ball connection device according to the connection status information of the inner and outer balls, and fix the inner ball on the outer ball.

[0019] In one alternative approach, the adjustment module controls an airbag located on the inner wall of the outer sphere in the inner and outer sphere connection device according to the connection status adjustment information, so that the airbag expands and contacts the inner sphere to limit and fix the inner sphere.

[0020] In one alternative approach, the receiving module is further configured to acquire the tilt angle of the inner sphere, the processing module generates inner sphere position adjustment information based on the tilt angle of the inner sphere, and the adjustment module controls the airbags located at different positions on the inner wall of the outer sphere in the inner and outer sphere connecting device to simultaneously inflate and deflate based on the inner sphere control adjustment information, thereby adjusting the position of the inner sphere.

[0021] This invention, by receiving information about the fixed position of the inner sphere, can convert the soft connection between the inner and outer spheres into a fixed connection before a typhoon or changes in the external environment, preventing the inner sphere from swaying or misaligning relative to the outer sphere and ensuring the stability of the double-layered spherical tank. The connecting device can adjust the connection state between the inner and outer spheres. When there is no external force, a soft connection is established to disperse the force of the inner sphere on the outer sphere and reduce damage to the external support pillars of the outer sphere. When there is an external force, the inner and outer spheres are fixed together to prevent the inner sphere from swaying or misaligning relative to the outer sphere, thus meeting the different connection requirements of the double-layered spherical tank.

In order to better understand the technical means of the embodiments of the present invention and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0027] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0028] The reference numerals in the accompanying drawings of the instruction manual include: 1. Support ring; 2. Support rib; 3. Annular reinforcing ring; 4. Inner ball.

[0029] Figure 1 A flowchart illustrating an embodiment of the inner sphere stabilization method for a double-walled spherical tank according to the present invention is shown. This method is performed by the inner sphere stabilization system of the double-walled spherical tank. Figure 1 As shown, the method includes the following steps:

[0030] Step 110: Receive information on the fixed position of the inner ball 4.

[0031] The information for fixing the position of the inner ball 4 includes: the current time, the time that the inner ball 4 needs to be fixed, and the position of the inner ball 4.

[0032] In this step, the fixed position information of the inner sphere 4 is received through communication devices such as 4G communication module and Bluetooth.

[0033] When external forecast information such as typhoons is received, it determines which areas of the double-layered ball tank will be affected, then generates the corresponding inner ball 4 position fixing information, and finally sends it to the communication equipment of the corresponding double-layered ball tank.

[0034] Step 120: Generate the connection status adjustment information between the inner and outer spheres based on the fixed position information of the inner sphere 4.

[0035] The information on the connection status adjustment between the inner and outer balls includes: current time, connection device fixed time, and other information.

[0036] Step 130: Adjust the inner and outer ball connection device according to the inner and outer ball connection status adjustment information, and fix the inner ball 4 onto the outer ball.

[0037] Among them, as attached Figure 3 As shown, the inner and outer sphere connecting device includes: a support ring 1, a support rib 2, an annular reinforcing ring 3, an airbag, and an air pump for controlling the airbag. The annular reinforcing ring 3 is installed at the equator of the outer sphere. The support ring 1 is fixedly connected to the annular reinforcing ring 3 through the support rib 2. The support ring 1 and the support rib 2 are used to place the inner sphere 4. The airbag is set on the inner wall of the outer sphere. After the airbag is inflated, it can contact the outer wall of the inner sphere 4.

[0038] Both the support ring 1 and the support rib 2 are covered with rubber to reduce wear and damage to the outer wall of the inner ball 4.

[0039] In this step, the airbag on the inner wall of the outer sphere is adjusted according to the connection status of the inner and outer spheres. The airbag inflates and contacts the inner sphere 4 to limit and fix the inner sphere 4. The airbag conveniently fixes the inner sphere 4.

[0040] In this embodiment, there are three airbags, with two airbags symmetrically arranged on one side of the outer sphere and the other airbag located on the other side of the outer sphere.

[0041] The outer sphere has a maintenance cover at its bottom, which is detachably connected to the outer sphere shell. The maintenance cover is part of the outer sphere shell, and has a port in the middle for the inner sphere's 4-pipe to pass through.

[0042] In one optional approach, the method further includes acquiring the tilt angle of the inner sphere 4, generating position adjustment information for the inner sphere 4 based on the tilt angle, and then controlling the simultaneous inflation and deflation of airbags located at different positions on the inner wall of the outer sphere in the inner and outer sphere connecting device according to the inner sphere 4 control adjustment information, thereby adjusting the position of the inner sphere 4. Specifically, in the absence of external forces (such as typhoons), the tilt angle of the inner sphere 4 is acquired, and the inflated airbags are used to press the inner sphere 4 towards the deflated airbags, causing the inner sphere 4 to move and adjusting its position.

[0043] The number of inflatable airbags is greater than the number of deflated airbags.

[0044] In one optional approach, the method further includes obtaining the maximum angle difference of the inner ball 4's tilt angle within a preset time period, comparing the maximum angle difference with a preset angle difference, and generating airbag maintenance information if the maximum angle difference is greater than the preset angle difference. Specifically, this step involves fixing the inner ball 4, obtaining its tilt angle, and using the maximum angle difference to determine if the airbag is damaged, thus notifying the user to perform timely maintenance.

[0045] This invention allows for adjustment of the connection between the inner and outer spheres via an airbag. When no external force is applied, the airbag is in a contracted state, providing a soft connection and dispersing the force exerted on the inner sphere 4 against the outer sphere, reducing damage to the outer support structure. When an external force is applied, the airbag expands and comes into close contact with the outer wall of the inner sphere 4, fixing the inner and outer spheres together and preventing the inner sphere 4 from swaying or misaligning relative to the outer sphere, thus meeting the different needs of the double-layered spherical tank. By receiving information about the fixed position of the inner sphere 4, the soft connection between the inner sphere 4 and the outer sphere can be converted into a fixed connection before a typhoon arrives or before changes in the external environment, preventing the inner sphere 4 from swaying or misaligning relative to the outer sphere and ensuring the stability of the double-layered spherical tank. By obtaining the tilt angle of the inner sphere 4, it is possible to determine whether the airbag is damaged and to carry out timely repairs.

[0046] Figure 2 A schematic diagram of an embodiment of the inner sphere 4 stabilization system of the double-layered spherical tank of the present invention is shown. Figure 2 As shown, the device 200 includes: a receiving module 210, a processing module 220, and an adjustment module 230.

[0047] The receiving module 210 is used to receive the positional information of the inner ball 4.

[0048] The processing module 220 is used to generate information for adjusting the connection state between the inner and outer balls based on the fixed position information of the inner ball 4.

[0049] The adjustment module 230 is used to adjust the inner and outer ball connection device according to the inner and outer ball connection status adjustment information, and fix the inner ball 4 on the outer ball.

[0050] In one alternative approach, the adjustment module 230 adjusts the airbag on the inner wall of the outer sphere in the inner and outer sphere connection device according to the connection status information, so that the airbag expands and contacts the inner sphere 4 to limit and fix the inner sphere 4.

[0051] In one optional embodiment, the receiving module 210 is further configured to acquire the tilt angle of the inner sphere 4, the processing module 220 generates position adjustment information for the inner sphere 4 based on the tilt angle, and the adjustment module 230 controls the simultaneous inflation and deflation of airbags located at different positions on the inner wall of the outer sphere in the inner and outer sphere connecting device based on the inner sphere 4 control adjustment information, thereby adjusting the position of the inner sphere 4. Specifically, in the absence of external forces (such as typhoons), the tilt angle of the inner sphere 4 is acquired, and the inflated airbags are used to press the inner sphere 4 towards the deflated airbags, causing the inner sphere 4 to move and adjusting its position.

[0052] In one alternative approach, the number of inflatable airbags is greater than the number of deflated airbags.

[0053] In one optional approach, the method further includes obtaining the maximum angle difference of the inner ball 4's tilt angle within a preset time period, comparing the maximum angle difference with a preset angle difference, and generating airbag maintenance information if the maximum angle difference is greater than the preset angle difference. The method involves obtaining the tilt angle of the inner ball 4 and using the maximum angle difference to determine if the airbag is damaged, thus notifying the user to perform timely maintenance.

[0054] In one alternative embodiment, the inner and outer sphere connecting device includes: a support ring 1, a support rib 2, an annular reinforcing ring 3, an air bladder, and an air pump for controlling the air bladder. The annular reinforcing ring 3 is installed at the equator of the outer sphere. The support ring 1 is fixedly connected to the annular reinforcing ring 3 via the support rib 2. The support ring 1 and the support rib 2 are used to place the inner sphere 4. The air bladder is disposed on the inner wall of the outer sphere, and after inflation, it can contact the outer wall of the inner sphere 4. Both the support ring 1 and the support rib 2 are covered with rubber to reduce wear and damage to the outer wall of the inner sphere 4.

[0055] In one alternative embodiment, a maintenance cover is provided at the bottom of the outer sphere, and the maintenance cover is detachably connected to the outer sphere shell.

[0056] In this embodiment of the invention, the receiving module 210 receives the position fixing information of the inner sphere 4, thereby determining whether it is necessary to fix the inner and outer spheres together in advance to prevent the inner sphere 4 from swaying relative to the outer sphere. The processing module 220 generates information for adjusting the connection state of the inner and outer spheres based on the position fixing information of the inner sphere 4. This information is used to control the air pump to control the inflation and deflation of the airbag. When there is no external force, a soft connection is established to disperse the force of the inner sphere 4 on the outer sphere and reduce damage to the external support of the outer sphere. When there is an external force, the inner and outer spheres are fixed together to prevent the inner sphere 4 from swaying or misaligning relative to the outer sphere, thus meeting the different needs of the double-layer spherical tank. The adjustment module 230 adjusts the inner and outer sphere connection device according to the inner and outer sphere connection state adjustment information to fix the inner sphere 4 onto the outer sphere. The soft connection between the inner sphere 4 and the outer sphere can be changed to a fixed connection before a typhoon arrives or before changes in the external environment, preventing the inner sphere 4 from swaying or misaligning relative to the outer sphere and ensuring the stability of the double-layer spherical tank.
