Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a layered fire protection terminal device for floating roof oil tanks. Background Technology

[0002] In recent years, large oil tank fires have become increasingly frequent, causing significant casualties and property damage, as well as widespread environmental pollution. Although floating roof tanks employ a perimeter sealing structure, complete sealing is impossible, leaving a possibility of small leaks of oil and gas from the sealing rings. These leaks can ignite under natural conditions such as exposure to sunlight or lightning strikes. To achieve early monitoring and prevention of oil tank fires, the use of online monitoring and active inerting technologies for protection on floating roof tanks has become a key research focus. However, the design and installation of online monitoring and inerting protection terminals are challenging due to the rise and fall of the floating roof along with the oil level in the tank.

[0003] Existing external floating roof tank protection devices utilize the tank's existing rotating floating ladder, with the protection device's piping arranged along it. However, this method is limited by the orientation of the rotating floating ladder during pipeline laying, increasing the difficulty of laying external pipelines and resulting in excessively long pipeline routes. Furthermore, the tank's floating roof has a large lifting range, and the rotating floating ladder converts the vertical lifting of the floating roof into the rotation of the ladder, thus requiring considerable space for movement.

[0004] Existing internal floating roof tanks lack rotating ramps, and the space above the floating roof is a large open area. Therefore, internal floating roof tanks lack corresponding fire protection devices. If the piping for fire protection devices is placed directly inside the tank without structural restraint and fixation, the movement of the piping within the tank will become irregular, easily leading to entanglement and damage, affecting monitoring and inerting protection.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] like Figures 1-2 As shown, this utility model provides a layered fire protection terminal device for floating roof oil tanks, including a first installation mechanism, a second installation mechanism, a scissor lift mechanism 7, and a pipe 10; the first installation mechanism is connected to the top plate 11 of the oil tank; the second installation mechanism is connected to the floating roof 12 of the oil tank; one end of the scissor lift mechanism 7 is rotatably connected to the first installation mechanism, and the other end is rotatably connected to the second installation mechanism; the pipe 10 is arranged along the scissor lift mechanism 7 through a connecting assembly.

[0043] The scissor lift mechanism 7 of this invention is connected at one end to the top plate 11 of the oil tank via a first mounting mechanism, and at the other end to the floating roof 12 of the oil tank via a second mounting mechanism. This allows the scissor lift mechanism 7 to adaptively move vertically up and down with the floating roof 12, maintaining synchronous movement with the floating roof 12. It requires less space, does not occupy excessive internal space of the internal floating roof oil tank, and improves the stability and reliability of the connection between the device and the internal floating roof oil tank. Furthermore, the pipe 10 is arranged along the scissor lift mechanism 7 via connecting components, effectively fixing the pipe 10 and ensuring stable movement as the floating roof 12 moves up and down, preventing entanglement and damage. The installation of this invention does not rely on a rotating floating ladder, therefore it can be widely applied in internal floating roof oil tanks. The installation location is unrestricted, the installation process is simple and quick, and there is no need to lay the pipe 10 around it, greatly saving on the material used for the pipe 10.

[0044] As an optional implementation, the first mounting mechanism includes a first mounting base 1, a first mounting plate 2, and a first mounting rod 3; the first mounting base 1 has a plurality of first through holes and is connected to the top plate 11 of the oil tank by bolts; there are two first mounting plates 2, which are arranged opposite to each other on the bottom plate of the first mounting base 1, together forming a clamping space for clamping the first mounting rod 3; the two first mounting plates 2 and the first mounting rod 3 are hinged by a pin.

[0045] Furthermore, the number of first through holes can be designed to be three, four, or more, depending on the usage requirements, to accommodate different oil tank connection needs.

[0046] Bolts are used to connect the first mounting base 1 to the top plate 11 of the oil tank through the first through hole, so as to securely connect the first mounting base 1 to the top plate 11 of the oil tank, thereby enabling the entire device to be stably installed on the internal floating roof oil tank.

[0047] The first mounting plate 2 is welded to the base plate of the first mounting seat 1, forming a clamping space for securely clamping the first mounting rod 3. Furthermore, the two first mounting plates 2 and the first mounting rod 3 are hinged together by a pin, allowing the first mounting rod 3 to rotate relative to the first mounting plate 2.

[0048] As an optional implementation, the second mounting mechanism includes a second mounting base 4, a second mounting plate 5, and a second mounting rod 6; the second mounting base 4 has a plurality of second through holes and is connected to the floating roof 12 of the oil tank by bolts;

[0049] There are two second mounting plates 5, which are arranged opposite each other on the top plate 11 of the second mounting base 4, together forming a clamping space for clamping the second mounting rod 6; the two second mounting plates 5 and the second mounting rod 6 are hinged together by a pin.

[0050] Furthermore, the number of second through holes can be designed to be three, four, or more, depending on the usage requirements, to accommodate different oil tank connection needs.

[0051] Bolts are used to connect the second mounting base 4 to the floating roof 12 of the oil tank through the second through hole, so as to securely connect the second mounting base 4 to the floating roof 12 of the oil tank. This allows the scissor lift mechanism 7 to adapt to the vertical lifting motion as the floating roof 12 floats, maintaining synchronous movement with the floating roof 12.

[0052] The second mounting plate 5 is welded to the top plate 11 of the second mounting base 4, together forming a clamping space for securely clamping the second mounting rod 6. Furthermore, the two second mounting plates 5 and the second mounting rod 6 are hinged together by a pin, allowing the second mounting rod 6 to rotate relative to the second mounting plates 5.

[0053] As an optional implementation, the number of scissor lift mechanisms 7 is two sets, with identical structures and arranged opposite each other; each set of scissor lift mechanisms 7 includes multiple sets of connecting plate assemblies, the connecting plate assembly including a first connecting plate and a second connecting plate; the upper ends of the first connecting plate a71 and the second connecting plate a72 of the uppermost connecting plate assembly are both hinged to the first mounting rod 3; the middle parts of the first connecting plate b73 and the second connecting plate b74 of the middle connecting plate assembly are hinged; the lower ends of the first connecting plate c75 and the second connecting plate c76 of the lowermost connecting plate assembly are hinged to the second mounting rod 6; the connecting ends of adjacent connecting plate assemblies are hinged to each other.

[0054] Furthermore, the upper ends of the first connecting plate a71 and the second connecting plate a72 located at the top are both hinged to the journal of the first mounting rod 3, forming the upper support of the scissor-type lifting mechanism 7. During the lifting process, the first connecting plate a71 and the second connecting plate a72 rotate relative to each other around the journal of the first mounting rod 3 to achieve the lifting action.

[0055] The first connecting plate b73 and the second connecting plate b74, located in the middle position, are hinged together by a pin. During the lifting and lowering process, the first connecting plate b73 and the second connecting plate b74 rotate relative to each other around the pin, thereby realizing the lifting and lowering action. Moreover, the number of connecting plate assemblies located in the middle position can be designed as one, two, three or more sets according to usage requirements to adapt to the needs of different oil tanks.

[0056] The lower ends of the first connecting plate c75 and the second connecting plate c76, located at the bottom, are hinged to the journal of the second mounting rod 6, forming the lower support of the scissor lift mechanism 7. During the lifting process, the first connecting plate c75 and the second connecting plate c76 rotate relative to each other around the journal of the second mounting rod 6, realizing the lifting action. At the same time, since the second mounting rod 6 is hinged to the second mounting plate 5, the second mounting rod 6 can rotate relative to the second mounting plate 5. It can also move adaptively with the floating roof 12. During the lifting process, the scissor lift mechanism 7 forms a structure similar to a universal joint, so that the normal operation of the entire device is not affected by the tilting or translation of the floating roof 12 of the oil tank.

[0057] The connecting ends of adjacent connecting plate assemblies are hinged by pins to ensure integrity and coordination during the lifting process. The pins serve as the hinge points between adjacent connecting plate assemblies, allowing them to rotate relative to each other during lifting to achieve the lifting action.

[0058] There are two sets of scissor lift mechanisms 7, which are identical in structure and arranged opposite to each other, providing the device with a stable, balanced and reliable lifting function.

[0059] It should be noted that the rotational movement of the first and second connecting plates of the connecting plate assembly around their hinge point is the basic working principle of the scissor lift mechanism 7. Furthermore, the first and second connecting plates include, but are not limited to, connecting components such as chain plates in the prior art, which will not be elaborated here.

[0060] As an optional implementation, the first and second connecting plates located at the top and bottom are V-shaped, while the first and second connecting plates located in the middle are X-shaped.

[0061] As an optional implementation, the length of the first connecting plate b73 and the second connecting plate b74 located in the middle position is twice the length of the first connecting plate a71 and the second connecting plate a located at the top, and the first connecting plate c75 and the second connecting plate c76 located at the bottom.

[0062] As an optional implementation, a connecting assembly is disposed between the two sets of scissor lift mechanisms 7 to connect the two sets of scissor lift mechanisms 7 and form the installation path of the pipe 10.

[0063] The connecting assembly can securely connect the two sets of scissor lift mechanisms 7 together to form a more stable and reliable overall structure. At the same time, it provides a continuous installation path for the laying of the pipe 10, so that the pipe 10 can move synchronously with the lifting of the scissor lift mechanism 7, while maintaining the stability and safety of the pipe 10.

[0064] As an optional implementation, the connecting assembly includes a connecting cylinder 8 and a fixing member 9. The connecting cylinder 8 is connected to the connecting end of an adjacent connecting plate assembly; the fixing member 9 is connected to a first connecting plate or a second connecting plate, and the fixing member 9 has a plurality of fixing holes 91 for the pipe 10 to pass through.

[0065] The connecting cylinder 8 is connected to the pins at the connecting ends of the adjacent connecting plate assemblies of the two sets of scissor lift mechanisms 7, so as to connect the connecting plate assemblies of the two sets of lift mechanisms together to form a stable integral structure and improve the connection strength. At the same time, it provides a foundation for the installation and restraint of the pipeline 10.

[0066] The fasteners 9 are respectively installed above and below the connecting cylinder 8, providing additional support and fixing points for the pipe 10. In addition, the fixing holes 91 are arranged sequentially along the length of the fasteners 9 to support and constrain the pipe 10, and can also adapt to the needs of different layouts of the pipe 10.

[0067] Pipe 10 is made of flexible hose, which has good flexibility and bendability. It can easily pass through the fixing hole 91 of the upper fixing member 9, go around the connecting cylinder 8, and then pass through the fixing hole 91 of the lower fixing member 9, so as to carry out continuous and stable laying from top to bottom.

[0068] The design of the connecting components of this utility model allows for the addition of pipes 10, pipe joints, valves, and other components at different positions of the scissor lift mechanism 7 as needed, thereby achieving layered protection at different levels.

[0069] As an optional implementation, at least one sampling head 101 is provided on the pipeline 10 for collecting oil samples from different levels inside the oil tank.

[0070] The position and number of sampling heads 101 can be designed and adjusted according to actual needs to accurately and effectively collect oil samples from the required levels.
