Description

Technical Field

[0001] This invention relates to the field of oil and gas sealing technology for storage tanks, and specifically to a method for installing a telescopic bladder for oil and gas collection without the need for climbing. Background Technology

[0002] During oil storage and transportation, due to limitations in technology and equipment, some light components in crude oil and light oils (such as gasoline) are easily released into the air, resulting in significant evaporation losses. In recent years, thanks to the application of floating roof tanks and internal floating roof tanks, the upgrading of floating roof equipment, and the implementation of other energy-saving measures, oil product losses have been brought under control.

[0003] like Figure 1 As shown, to collect the volatile oil and gas in storage tank 1, an oil and gas collection assembly is typically installed inside tank 1. This assembly includes a float 2, a telescopic sleeve 3, and a waveguide 4. The telescopic sleeve 3 is loosely fitted onto the waveguide 4. The lower end of the telescopic sleeve 3 is fixed to the float 2, and the upper end is fixed to the upper end of the waveguide 4. The lower end of the waveguide 4 engages with the bottom of storage tank 1, and the upper end of the waveguide 4 passes through the float 2. When oil is injected into storage tank 1, the float 2 rises axially along the tank 1 under the buoyancy of the oil. As the float 2 rises, it moves the lower end of the telescopic sleeve 3, causing it to contract. The telescopic sleeve 3 effectively solves and significantly reduces evaporation losses caused by the opening of the waveguide 4 itself and the contact between the liquid surface and air at the junction of the waveguide 4 and the float 2.

[0004] Typically, one to three oil and gas collection assemblies are installed inside storage tank 1. The waveguide 4 is also used to install radar level gauges, temperature measuring devices, oil measuring devices, and other components. The lower end of the waveguide 4 is fixed near the tank bottom by a bracket welded to the tank wall, while the upper end of the waveguide 4 is fixed to the tank top. The height from the upper end of the waveguide 4 to the tank bottom is over 12 meters. Since the upper end of the telescopic bladder sleeve 3 is fixed to the upper end of the waveguide 4, the following methods are currently used for installing the upper end of the telescopic bladder sleeve 3 to the upper end of the waveguide 4:

[0005] First, scaffolding is erected. Operators climb the scaffolding to reach the top of the storage tank 1 and use clamps to secure the upper end of the telescopic bladder sleeve 3 to the upper end of the waveguide tube 4. This method requires erecting and then dismantling the scaffolding after installation, making the process time-consuming, labor-intensive, inefficient, and costly.

[0006] Second, trial installation: Operators enter the tank 1 through the manhole located at the bottom and stand on the floating roof 2. Liquid is injected into the floating roof (generally for new products to test the seal between the floating roof and the tank 1) to raise the floating roof 2. After it rises to the designated position, the operator uses clamps to tighten the upper end of the telescopic bladder sleeve 3 to the upper end of the waveguide tube 4 to form a fixed structure. This operation requires injecting a large amount of water into the tank 1, resulting in a long injection time and low efficiency. Summary of the Invention

[0007] This invention provides a method for installing a telescopic bladder without climbing, which has the advantages of simple operation and safety.

[0008] The technical solution to achieve the above objectives is as follows:

[0009] The method for installing the telescopic bladder sleeve without climbing includes the following steps:

[0010] S1, the motor is installed inside the sleeve assembly, and the drive wheel is connected to the output end of the motor;

[0011] S2, the sleeve assembly and the self-locking internal clamping mechanism are respectively fitted onto the waveguide, and the self-locking internal clamping mechanism is engaged with the sleeve assembly. The unlocking mechanism is engaged with the sleeve assembly with a clearance, and the unlocking mechanism is in contact with the self-locking internal clamping mechanism, so that the drive wheel is engaged with the circumferential surface of the waveguide.

[0012] S3 puts the self-locking internal clamping mechanism in the open state, creating a gap between the self-locking internal clamping mechanism and the waveguide.

[0013] S4, Connect the plug of the conductive wire to the motor, connect the conductive wire to the power supply battery, and put the telescopic bladder on the sleeve assembly and fix it to the sleeve assembly.

[0014] S5, put the telescopic bladder sleeve on the sleeve assembly, pull up the upper zipper of the telescopic bladder sleeve, and fix the upper end of the telescopic bladder sleeve to the sleeve assembly;

[0015] S6, start the motor, the motor drives the drive wheel to rotate, and under the frictional force between the drive wheel and the waveguide, the self-locking internal clamping mechanism, sleeve assembly, unlocking mechanism and telescopic bladder sleeve climb up along the waveguide;

[0016] S7, when the unlocking mechanism abuts against the top wall of the storage tank, the abutting force formed by the unlocking mechanism and the storage tank is transmitted to the self-locking inner tightening clamping mechanism, releasing the lock of the self-locking inner tightening clamping mechanism, the self-locking inner tightening clamping mechanism automatically tightens the waveguide tube, and finally connects the lower end of the telescopic bladder to the floating plate.

[0017] By employing the above-described scheme, this invention enables the motor to rotate the drive wheel after it starts working. The friction between the drive wheel and the waveguide causes the self-locking internal clamping mechanism, sleeve assembly, unlocking mechanism, and telescopic sleeve to climb along the waveguide. This, in turn, causes the upper end of the telescopic sleeve, fixed to the sleeve assembly, to reach the top of the waveguide. The unlocking mechanism, through its contact with the tank, generates a counterforce that is transmitted to the self-locking internal clamping mechanism, releasing its lock. The self-locking internal clamping mechanism then automatically clamps the waveguide, finally connecting the lower end of the telescopic sleeve to the floating roof. Therefore, the entire installation process only requires assembling the self-locking internal clamping mechanism, sleeve assembly, unlocking mechanism, and telescopic sleeve. The motor and drive wheel automatically drive the telescopic sleeve to climb. The entire process is simple and completely avoids the scaffolding or water-filled installation methods found in existing technologies. Compared to the prior art, this invention is highly efficient, easy to operate, eliminates the need for high-altitude work, and is also safer. Attached Figure Description

[0029] The invention will now be further described with reference to the accompanying drawings.

[0030] like Figures 1 to 6 As shown, the no-climbing installation device for the telescopic bladder 3 of the present invention includes a waveguide 4 and an automatic lifting device for driving the telescopic bladder 3 to rise and fall. The waveguide 4 passes through a floating plate 2 located inside the storage tank 1. The initial position of the automatic lifting device is located in the lower middle part of the waveguide 4, and the automatic lifting device is in an expanded state and has a clearance fit with the waveguide 4. The automatic lifting device is supported on the floating plate 2. When installing the telescopic bladder 3, the upper end of the telescopic bladder 3 is first fixed to the automatic lifting device. The automatic lifting device is then started, and it moves along the axial direction of the waveguide 4 to the upper end of the waveguide 4, thereby driving the telescopic bladder 3 to move to the upper end of the waveguide 4.

[0031] like Figure 2 As shown, the automatic lifting device includes a self-locking internal clamping mechanism A, a sleeve assembly B, a motor C, a drive wheel D, and an unlocking mechanism E. The following is a detailed description of each part of the automatic lifting device and the relationships between them:

[0032] like Figures 2 to 6 As shown, the self-locking internal tightening clamping mechanism A cooperates with the waveguide 4. The waveguide 4 has a first pipe section that is in clearance fit with the self-locking internal tightening clamping mechanism A, and a second pipe section that is fixed to the self-locking internal tightening clamping mechanism A. The outer diameter of the first pipe section and the outer diameter of the second pipe section can be equal. When the self-locking internal tightening clamping mechanism A is located in the first pipe section, it is in an open state. Therefore, when the self-locking internal tightening clamping mechanism A is located in the first pipe section, it forms a clearance fit with the first pipe section. When the self-locking internal tightening clamping mechanism A is located in the second pipe section, the open state of the self-locking internal tightening clamping mechanism A is automatically released, so the self-locking internal tightening clamping mechanism A automatically tightens the second pipe section when it is located in the second pipe section.

[0033] like Figures 3 to 6 As shown, the self-locking internal tightening clamping mechanism A includes a first clamping component 10, a second clamping component 13, and an expansion assembly. One end of the first clamping component 10 is provided with a first connecting part 11, and the other end of the first clamping component 10 is provided with a second connecting part 12. In this embodiment, the first clamping component 10 is semi-circular. The first connecting part 11 and the second connecting part 12 are both provided on the circumferential surface of the first clamping component 10. The first connecting part 11 and the second connecting part 12 are preferably integrally formed with the first clamping component 10, for example, by casting.

[0034] like Figures 3 to 6As shown, one end of the second clamping component 13 is provided with a third connecting part 14, and the other end of the second clamping component 13 is provided with a fourth connecting part 15. In this embodiment, the second clamping component 13 is semi-circular, and the third connecting part 14 and the fourth connecting part 15 are both provided on the circumferential surface of the second clamping component 13. The third connecting part 14 and the fourth connecting part 15 are preferably integrally formed with the first clamping component 10, for example, by casting.

[0035] like Figures 3 to 6 As shown, the first clamping component 10 and the second clamping component 13 combine to form a ring. In this embodiment, the first clamping component 10 and the second clamping component 13 combine to form a ring. The inner diameter of the ring is less than or equal to the outer diameter of the waveguide 4. Therefore, the first clamping component 10 and the second clamping component 13 combine to form a ring around the waveguide 4.

[0036] like Figures 3 to 6 As shown, the first connecting part 11 and the third connecting part 14 are fixed, so that one end of the first clamping member 10 and the second clamping member 13 are fastened together. The other ends of the first clamping member 10 and the second clamping member 13 are engaged. When there is no tension force, the other ends of the first clamping member 10 and the second clamping member 13 abut against each other. When the first clamping member 10 and the second clamping member 13 are subjected to tension force, the other ends of the first clamping member 10 and the second clamping member 13 separate and a gap is generated.

[0037] like Figures 3 to 6 As shown, since one end of the first clamping component 10 and the second clamping component 13 are fastened together by components such as screws or rivets, and the other end of the first clamping component 10 and the second clamping component 13 is a free end, that is, not restrained, when the first clamping component 10 and the second clamping component 13 are subjected to the force of expansion, both the first clamping component 10 and the second clamping component 13 will undergo elastic deformation and accumulate elastic potential energy.

[0038] like Figures 3 to 6 As shown, the second connecting part 12 and the fourth connecting part 15 cooperate. In this embodiment, there is a gap between the second connecting part 12 and the fourth connecting part 15. The second connecting part 12 and the fourth connecting part 15 are used to cooperate with the expansion component. The force generated by the expansion component on the first clamping component 10 and the second clamping component 13 makes the first clamping component 10 and the second clamping component 13 in an expanded state, so that the self-locking internal clamping mechanism A is in gap cooperation with the first pipe section when it is located in the first pipe section of the waveguide 4.

[0039] like Figures 3 to 6As shown, the expansion component cooperates with the unlocking mechanism E. The expansion component includes a first connector 16 and a second connector 17. One end of the first connector 16 is threadedly connected to the second connecting part 12. One end of the second connector 17 cooperates with the other end of the first connector 16. After the other end of the second connector 17 abuts against the fourth connecting part 15, the first clamping component 10 and the second clamping component 13 expand.

[0040] like Figures 3 to 6 As shown, in this embodiment, the first connector 16 is preferably a bolt. By rotating the first connector 16, the first connector 16 moves along the axial direction of the second connecting part 12, thereby driving the second connector 17 to feed towards the fourth connecting part 15. The second connector 17 first forms abutment with the fourth connecting part 15. As the feed amount of the first connector 16 increases, the expansion assembly separates the other ends of the first clamping part 10 and the second clamping part 13. After adjusting to a suitable size, for example, after expansion, the inner diameter of the ring formed by the first clamping part 10 and the second clamping part 13 is more than 2 mm larger than the outer diameter of the waveguide 4, the operation of the expansion assembly can be stopped.

[0041] like Figures 3 to 6 As shown, one end of the second connector 17 is hinged to the other end of the first connector 16, and the other end of the second connector 17 is a free end. When the unlocking mechanism E applies a pushing force to the second connector 17, the second connector 17 is separated from the fourth connecting part 15. The second connector 17 rotates around the hinge under its own weight. In this way, the tension state generated by the expansion assembly on the first clamping part 10 and the second clamping part 13 is released, the first clamping part 10 and the second clamping part 13 are reset, and the second clamping part 10 and the second clamping part 13 form a clamping state on the second section of the waveguide 4.

[0042] like Figures 3 to 6 As shown, one end of the second connector 17 can also be abutted against the other end of the first connector 16. In this case, the second connector 17 is clamped between the first connector 16 and the fourth connecting part 15. When the first connector 16 is rotated, the force is transmitted to the fourth connecting part 15 through the second connector 17. As the feed amount of the first connector 16 increases, the expansion assembly separates the other ends of the first clamping member 10 and the second clamping member 13. In this structure, when the tension is released, when the unlocking mechanism E applies a pushing force to the second connector 17, the second connector 17 separates from the fourth connecting part 15 and the first connector 16, and the first clamping member 10 and the second clamping member 13 reset, forming a clamping state for the second segment of the waveguide 4.

[0043] like Figures 3 to 6As shown, the end face of the second connector 17 that abuts against the fourth connector 15 is composed of an arc-shaped surface 17a and a flat surface 17b. When the second connector 17 abuts against the fourth connector 15, it abuts against the fourth connector 15 through the flat surface 17b, while the arc-shaped surface 17a does not abut against the fourth connector 15. The purpose of setting the end face of the second connector 17 to be composed of an arc-shaped surface 17a and a flat surface 17b is to reduce the contact area with the fourth connector 15. When the unlocking mechanism E applies a pushing force to the second connector 17, the requirement for the pushing force can be reduced, thus ensuring the release of the expansion state.

[0044] like Figures 3 to 6 As shown, the self-locking internal tightening clamping mechanism A also includes a tension spring 18. One end of the tension spring 18 is fixed to the second connecting part 12, and the other end of the tension spring 18 is fixed to the fourth connecting part 15. When the first clamping component 10 and the second clamping component 13 are expanded by the expansion assembly, the tension spring 18 is stretched. After the first clamping component 10 and the second clamping component 13 are released from the expanded state, the tension spring 18 tightens the first clamping component 10 and the second clamping component 13.

[0045] like Figures 3 to 6 As shown, after the first clamping component 10 and the second clamping component 13 are released from their open state, the tightening force generated by the tension spring 18 on the first clamping component 10 and the second clamping component 13 ensures the clamping state of the first clamping component 10 and the second clamping component 13 on the waveguide 4.

[0046] like Figures 3 to 6 As shown, since the actual length of the tension spring 18 is less than the gap between the second connecting part 12 and the fourth connecting part 15, after the tension spring 18 is connected to the second connecting part 12 and the fourth connecting part 15, and when the force of the expansion assembly is released, the tension spring 18 generates a tightening force on the second connecting part 12 and the fourth connecting part 15, thereby indirectly generating a tightening force on the first clamping member 10 and the second clamping member 13, so that the first clamping member 10 and the second clamping member 13 can reliably clamp the waveguide 4.

[0047] like Figures 3 to 6 As shown, the inner walls of the first clamping component 10 and the second clamping component 13 are provided with protruding teeth 19. A flexible sleeve (not shown in the figure) is fixed on the second pipe segment. After the first clamping component 10 and the second clamping component 13 are closed, at least a portion of the protruding teeth 19 is pressed into the flexible sleeve, which increases the reliability of the first clamping component 10 and the second clamping component 13 in clamping the waveguide 4. When this structure is adopted, the outer diameter of at least a portion of the second pipe segment is set to be smaller than the outer diameter of the first pipe segment to accommodate the flexible sleeve, and the outer diameter of the flexible sleeve is the same as the outer diameter of the first pipe segment.

[0048] like Figure 2As shown, sleeve assembly B is loosely fitted onto waveguide 4. All parts in sleeve assembly B that fit onto waveguide 4 are composed of two halves, for example, two semicircular rings. The two semicircular rings are joined together and then fixed by welding or riveting. Sleeve assembly B cooperates with internal tightening mechanism A. Sleeve assembly B includes a sleeve 20, an upper mounting plate 21 with a through hole, and a bracket 22 for mounting motor C. The upper mounting plate 21 is located inside the sleeve 20 and fixed to the sleeve 20, and the bracket 22 is fixed to the upper mounting plate 21.

[0049] like Figure 2 As shown, the sleeve assembly B also includes a slide rail 23 and a spring 24. The slide rail 23 is slidably engaged with the bracket 22, one end of the spring 24 is engaged with the sleeve 20, and the other end of the spring 24 is engaged with the bracket 22, so that the engagement between the drive wheel D and the circumference of the waveguide 4 is maintained.

[0050] like Figure 2 As shown, with this structure, the tension of the spring 24 pushes the bracket 22, the bracket 22 drives the motor C to move, the motor C drives the drive wheel D to move, so that the drive wheel D cooperates with the waveguide 4. As can be seen from the above, under the action of the tension of the spring 24, the cooperation between the drive wheel D and the waveguide 4 can always be maintained, so as to ensure that when the motor C drives the drive wheel D, the friction force generated between the drive wheel D and the waveguide 4 can drive the installation device to rise.

[0051] like Figure 2 As shown, the sleeve assembly B further includes a lower mounting plate 25 with a through hole and a connecting assembly. The lower mounting plate 25 cooperates with the self-locking internal tightening mechanism A, and the connecting assembly is fixed to the lower mounting plate 25 and also fixed to the sleeve 20. In this embodiment, the self-locking internal tightening mechanism A is placed on the lower mounting plate 25, and the lower mounting plate 25 provides a supporting force for the self-locking internal tightening mechanism A.

[0052] like Figure 2 As shown, the connecting assembly includes an angle connector 26 and a connecting block 27. The angle connector 26 is fixed to the sleeve 20, the connecting block 27 is fixed to the angle connector 26, and the angle connector 26 or the connecting block 27 is fixed to the lower mounting plate 25.

[0053] like Figure 2As shown, there are multiple motors C, each located inside and connected to the sleeve assembly B. In this embodiment, motor C is connected to bracket 22. Motor C is provided with a plug-in connector, which is a plug-and-play connector used to connect the plug of the conductive wire. The conductive wire rises together with the plug, and the other end of the conductive wire is located on the floating plate 2 and connected to the power supply battery. When the installation device rises to the top of the waveguide 4 and the self-locking internal clamping mechanism A clamps the waveguide 4, the plug and the plug-in connector are connected together, which applies a pulling force to the conductive wire, causing the conductive wire to separate from the plug-in connector, thereby recovering the conductive wire and the plug.

[0054] like Figure 2 As shown, each motor C's output terminal is connected to a drive wheel D, which engages with the circumferential surface of the waveguide 4. In this embodiment, the drive wheel D is preferably a rubber roller. Since the waveguide 4 is made of iron, the use of a rubber roller to engage with the waveguide 4 increases the friction between the drive wheel D and the waveguide 4, making it easier for the drive wheel D to climb upwards along the waveguide 4.

[0055] like Figure 2 As shown, preferably, a guide groove (not shown in the figure) extending along the axial direction of the waveguide 4 is provided on the outer surface of the waveguide 4. The drive wheel D cooperates with the guide groove. This structure can increase the contact area between the drive wheel D and the waveguide 4, increase the friction, and make it easier for the drive wheel D to climb. On the other hand, since the guide groove guides the drive wheel D, it prevents the drive wheel D from moving in other directions of the waveguide 4, thereby avoiding the state where the telescopic sleeve 1 will not rotate and wrap when the installation device drives the telescopic sleeve 1 to rise, that is, ensuring that the telescopic sleeve 1 rises in a straight line.

[0056] like Figure 2 As shown, after the unlocking mechanism E moves, it forms abutment with the top of the storage tank 1. The unlocking mechanism E is connected to the sleeve B assembly. The unlocking mechanism E cooperates with the self-locking internal tightening clamping mechanism A. After the automatic lifting device moves along the first pipe section to the second pipe section, the abutting force formed when the unlocking mechanism E abuts with the storage tank 1 is transmitted to the self-locking internal tightening clamping mechanism A, releasing the lock of the self-locking internal tightening clamping mechanism A. The self-locking internal tightening clamping mechanism A automatically clamps the second pipe section.

[0057] like Figure 2As shown, the unlocking mechanism E includes a pressure cap 30, a push rod 31, and an elastic component 32. The pressure cap 30 is clearance-fitted with the sleeve 20. When the pressure cap 30 is under force, it can move along the sleeve 20. The pressure cap 30 is composed of two semi-circular caps joined together, and the pressure cap 30 is annular. The pressure cap 30 is clearance-fitted with the waveguide 4. The pressure cap 30 is provided with one or more protrusions 33 that cooperate with the top wall of the storage tank 1 to apply pressure to the pressure cap 30. Preferably, there are multiple protrusions 33, and the heights of the multiple protrusions 33 are set to be inconsistent according to the shape of the top wall of the storage tank 1, so as to make the pressure cap 30 evenly stressed and not jammed in the sleeve 20.

[0058] like Figure 2 As shown, one end of the push rod 31 is fixed to the pressure cap 30, and the other end of the push rod 31 passes through the sleeve assembly B and cooperates with the self-locking internal tightening clamping mechanism A. In this embodiment, the other end of the push rod 31 contacts the second connecting member 17. When the pressure cap 30 is moved by force, the pressure cap 30 drives the push rod 31 to move, and the push rod 31 applies a pushing force to the second connecting member 17, thereby releasing the opening state of the self-locking internal tightening clamping mechanism A, and the self-locking internal tightening clamping mechanism A resets and automatically clamps the waveguide 4.

[0059] like Figure 2 As shown, one end of the elastic component 32 engages with the pressure cap 30, and the other end engages with the sleeve assembly B. The other end of the elastic component 32 engages with the upper mounting plate 21 in the sleeve assembly B. The elastic component 32 is either a foamed plastic elastomer or a spring. In this embodiment, the elastic component 32 is preferably a foamed plastic elastomer. The elastic component 32 provides support to the pressure cap 30. When the pressure cap 30 is under pressure, it causes the elastic component 32 to foam, thus sealing the sleeve 20 and preventing oil vapor from escaping through the sleeve 20.

[0060] like Figures 2 to 6 As shown, the above-described installation device for the telescopic bladder sleeve is used to implement a method for installing the telescopic bladder sleeve without climbing, including the following steps:

[0061] S1, the motor C is installed inside the sleeve assembly B, and the drive wheel D is connected to the output end of the motor C.

[0062] S2, sleeve assembly B and self-locking internal clamping mechanism A are respectively sleeved on waveguide 4, and self-locking internal clamping mechanism A is engaged with sleeve assembly B, and unlocking mechanism E is engaged with sleeve assembly B with clearance, and unlocking mechanism E is in contact with self-locking internal clamping mechanism A, so that drive wheel D is engaged with the circumferential surface of waveguide 4.

[0063] S3 causes the self-locking internal clamping mechanism A to be in an open state, creating a gap between the self-locking internal clamping mechanism A and the waveguide 4.

[0064] S4, connect the plug of the conductive wire to the motor C, connect the conductive wire to the power supply battery, and put the telescopic bladder 3 on the sleeve assembly B and fix it to the sleeve assembly B.

[0065] S5, put the telescopic bladder sleeve on the sleeve assembly B, pull up the upper zipper of the telescopic bladder sleeve, and fix the upper end of the telescopic bladder sleeve to the sleeve assembly B.

[0066] S6, start motor C, motor C drives drive wheel D to rotate, under the frictional force between drive wheel D and waveguide 4, the self-locking internal tightening mechanism A, sleeve assembly B, unlocking mechanism E, and telescopic bladder sleeve climb along waveguide 4.

[0067] S7, when the unlocking mechanism E abuts against the top wall of the storage tank 1, the abutting force formed by the unlocking mechanism E and the storage tank 1 is transmitted to the self-locking internal tightening mechanism A, releasing the lock of the self-locking internal tightening mechanism A, and the self-locking internal tightening mechanism A automatically tightens the waveguide 4, and finally connects the lower end of the telescopic bladder to the floating plate.

[0068] Finally, it should be noted that the above embodiments are merely preferred embodiments of the present invention used to illustrate the technical solutions of the present invention, and are not intended to limit them, much less limit the patent scope of the present invention; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
