[0043] Figure 1 A structural diagram of the supporting device 2 in one embodiment is shown. Figure 3 FIG. 2 is a structural diagram of another embodiment of the support device 2. For ease of description, the vertical direction described below is the up-down direction shown in the figure.

[0044] like Figure 1 , Figure 3 As shown, the present application provides a storage tank, which includes a tank top platform 1 and at least one supporting device 2. The tank top platform 1 is located on the top of the storage tank. The supporting device 2 is arranged on the tank top platform 1, and the supporting device 2 is used to install a high-altitude instrument 3. The instrument 3 of the high-altitude instrument 3 is installed at a high height, and the instrument 3 at high altitude can be a flame detector and a combustible gas detector, etc., which can be used to monitor whether the storage tank is operating safely. At least one supporting device 2 can be one or more than two, and the more than two supporting devices 2 are arranged at intervals.

[0045] The supporting device 2 provided in the present application includes a mounting platform 22 , a supporting frame 21 , a fixing frame 23 and a locking mechanism 24 .

[0046] The mounting platform 22 and the fixing frame 23 are both fixed on the tank top platform 1, and the bottom of the support frame 21 is rotatably and / or detachably connected to the mounting platform 22, so that the support frame 21 can be erected on the mounting platform 22 or laid down to be horizontally located on the top of the tank top platform 1. The top of the support frame 21, that is, the other end of the support frame 21 away from the other end connected to the mounting platform 22, is used to install the instrument 3. The locking mechanism 24 can connect and lock the support frame 21 erected on the mounting platform 22 to the fixing frame 23 to achieve the positioning of the support frame 21. The support device 2 of the present application can provide a convenient installation, maintenance and inspection space for the instrument 3 installed at high altitude, without the need to disassemble and inspect the instrument 3 at high altitude, thereby reducing the safety hazards caused by high-altitude operations.

[0047] The support frame 21 being in a vertical state may mean that the support frame 21 is erected relative to the tank top platform 1 or even perpendicular to the tank top platform 1. The support frame 21 being in a horizontally laid down state may mean that the support frame 21 is placed on the tank top platform 1, or the support frame 21 is parallel to the top surface of the tank top platform 1, or there may be a certain gap or a certain angle between the support frame 21 and the tank top platform 1, etc.

[0048] In fact, the top and bottom of the support frame 21 are relative descriptions of the support frame 21 in an upright state. In fact, the support frame 21 has an axial first end and a second end. The first end of the support frame 21 is used to connect to the mounting platform 22, and the second end of the support frame 21 is used to install the instrument 3.

[0049] When the instrument 3 needs to be installed, the staff can first install the instrument 3 at the second end of the support frame 21 when the support frame 21 is in a laid-down state, and then rotate the first end of the support frame 21 upward relative to the mounting platform 22, or detachably install the first end of the support frame 21 on the mounting platform 22, so that the support frame 21 is erected as a whole on the mounting platform 22, and finally lock the support frame 21 on the fixing frame 23 through the locking mechanism 24. At this time, the instrument 3 is at the top of the support frame 21, and the installation of the instrument 3 is completed, which facilitates the installation of the high-altitude instrument 3.

[0050] When the instrument 3 needs to be repaired, replaced or removed, the locking mechanism 24 is released to unlock the support frame 21 and the fixing frame 23, and then the bottom of the support frame 21 is rotated downward relative to the mounting platform 22, or the bottom of the support frame 21 is removed from the mounting platform 22, and the support frame 21 is laid down on the tank top platform 1, so as to facilitate the maintenance and operation of the high-altitude instrument 3 by the staff.

[0051] It should be noted that the bottom of the support frame 21 is rotatably and / or detachably connected to the mounting platform 22, which means that the bottom of the support frame 21 can be only rotatably connected to the mounting platform 22, or only detachably connected to the mounting platform 22, or detachably rotatably connected to the mounting platform 22.

[0052] One, two or even more than two instruments 3 may be installed on a support frame 21. The instrument 3 may be a flame detector, a combustible gas detector, etc., which is specifically set according to the installation requirements.

[0053] Figure 2 for Figure 1 A partial enlarged view of area A in the middle.

[0054] Combination Figure 1 , Figure 2 As shown, the support frame 21 includes a main rod 211 and a cross rod 212 that are cross-connected to each other, the cross rod 212 is rotatably or detachably connected to the mounting platform 22, one end of the main rod 211 is fixedly connected to the cross rod 212, and the other end of the main rod 211 is used to mount the instrument 3; the locking mechanism 24 is configured to lock the main rod 211 and the fixing frame 23. The main rod 211 of the support frame 21 is used to mount the instrument 3, the cross rod 212 is cross-connected to the main rod 211, and the arrangement of the cross rod 212 facilitates the connection with the mounting platform 22, so that the support frame 21 can be mounted on the mounting platform 22 as a whole.

[0055] Specifically, the cross bar 212 is arranged perpendicular to the main rod 211, and the cross bar 212 is arranged on one axial end of the main rod 211, and the axial ends of the cross bar 212 extend along the radial sides of the main rod 211 respectively, so that the cross bar 212 and the main rod 211 form a T-shaped rod structure. In addition, the cross bar 212 can also be arranged at a position close to one axial end of the main rod 211, so that the cross bar 212 and the main rod 211 form a cross-shaped rod structure. In some other embodiments, one axial end of the cross bar 212 can also be connected to the main rod 211, and the other axial end of the cross bar 212 extends outward along the radial direction of the main rod 211. The end of the cross bar 212 away from the main rod 211 can be rotatably connected to the mounting platform 22, and at this time, the cross bar 212 serves as the rotating shaft of the main rod 211 to realize the swing of the main rod 211. Alternatively, one end of the cross bar 212 away from the main bar 211 is detachably connected to the mounting platform 22 , so that the cross bar 212 can be fixed to or detached from the mounting platform 22 .

[0056] In this embodiment, the mounting platform 22 includes two bases 221 spaced apart on the top surface of the tank top platform 1, and the side walls of the bases 221 are provided with mounting holes, and the mounting holes of the two bases 221 are arranged opposite to each other. The axial ends of the crossbar 212 are respectively inserted into the mounting holes on the two bases 221 one by one. The crossbar 212 can rotate in the mounting hole. The support frame 21 as a whole can be switched between an upright state and a horizontally laid state by rotation. When the support frame 21 is upright, there is no need for alignment installation, which saves time and effort, and is convenient for the staff to use and disassemble the instrument 3.

[0057] Specifically, the spacing between the two bases 221 is smaller than the axial dimension of the crossbar 212, so that the crossbar 212 can be inserted into the mounting holes on the two bases 221 and remain fixed, thereby realizing the installation of the crossbar 212. The base 221 can be an angle steel, rigidly connected to the tank top platform 1. In the case where the crossbar 212 only extends along one radial side of the main rod 211, only one base 221 can be provided, and the end of the crossbar 212 away from the main rod 211 penetrates into the base 221, and can be stuck on the base 221 through a limiting structure to prevent the crossbar 212 from falling off.

[0058] Furthermore, in order to further facilitate the inspection and replacement of the high-altitude instrument 3 and the replacement of the support frame 21, the cross bar 212 is rotatably and detachably connected to the two bases 221.

[0059] Specifically, the mounting hole is processed at an appropriate height on the side wall of the base 221. The inner diameter of the mounting hole is larger than the outer diameter of the cross bar 212, and is about 3 mm larger. The staff can first obliquely insert one end of the cross bar 212 into the mounting hole on one base 221. The insertion length can adjust the cross tube to be flat, and the cross tube can be moved axially to pass through the mounting hole of another base 221. Then the position of the cross bar 212 is adjusted so that the cross bar 212 is stably supported in the two mounting holes.

[0060] Furthermore, at least one positioning pin 213 is provided on the cross bar 212, and the positioning pin 213 protrudes from the outer peripheral wall of the cross bar 212. The positioning pin 213 is located at a position of the cross bar 212 close to the base 221, and is used to limit the axial movement of the cross bar 212 and prevent the cross bar 212 from falling off between the two mounting holes. When the cross bar 212 needs to be removed from the base 221, the positioning pin 213 is first removed, and the position of the cross bar 212 is axially adjusted so that the end of the cross bar 212 can fall off from the mounting hole. In this embodiment, the cross bar 212 is provided with positioning pins 213 on both sides close to the two bases 221, respectively, to further improve the installation stability of the cross bar 212.

[0061] In some other embodiments, the top surface of the mounting platform 22 may be provided with a mounting hole, the bottom of the support frame 21 may be inserted into the mounting hole, and locked on the mounting platform 22 and the fixing frame 23 by a detachable locking mechanism 24 such as a bolt, a pin, a clamp, a pipe clamp, etc., to achieve a detachable connection between the support frame 21 and the mounting platform 22. Alternatively, the two bases 221 of the mounting platform 22 may be provided with a shaped hole matching the cross-sectional shape of the cross bar 212, so that the cross bar 212 is positioned after being inserted into the shaped hole.

[0062] The height of the support frame 21 in the upright state needs to meet the installation height of the high-altitude instrument 3, so the height of the support frame 21 is relatively high. In order to ensure the stability of the support frame 21 and improve the installation stability of the instrument 3, further, the fixing frame 23 is fixed on the tank top platform 1, and the fixing frame 23 can be arranged in parallel with the support frame 21 in the upright state, so that the locking mechanism 24 can lock the support frame 21 on the fixing frame 23, and then the fixing frame 23 can support the support frame 21. After the locking mechanism 24 locks the support frame 21 and the fixing frame 23, the support frame 21 and the fixing frame 23 fit each other, reducing the shaking of the support frame 21.

[0063] Specifically, the fixing frame 23 is a steel structure guardrail frame to improve stability. The fixing frame 23 can be installed on the tank top platform 1 after the support frame 21 is erected, thereby improving installation accuracy, reducing the gap between the support frame 21 and the fixing frame 23, or preventing the support frame 21 from tilting.

[0064] Furthermore, the height of the fixing frame 23 is at least half of the height of the supporting frame 21 , that is, the height of the fixing frame 23 is at least half of the axial length of the supporting frame 21 , thereby improving the supporting stability of the fixing frame 23 on the supporting frame 21 .

[0065] In this embodiment, there are multiple locking mechanisms 24, which are spaced apart in the up-and-down directions, and can provide multiple locking connection points between the erected support frame 21 and the fixing frame 23, thereby further improving the positioning stability of the support frame 21.

[0066] Figure 4It is a structural diagram of the locking mechanism 24 locking the supporting frame 21 and the fixing frame 23.

[0067] Furthermore, the locking mechanism 24 includes a first U-shaped bolt 241 and a first nut 242. The first U-shaped bolt 241 has external threads at opposite ends thereof. The first U-shaped bolt 241 passes through the fixing frame 23 at opposite ends thereof. The first nut 242 threads and locks the first U-shaped bolt 241 passing through the fixing frame 23, thereby realizing a detachable connection between the first U-shaped bolt 241 and the support frame 21. The first U-shaped bolt 241 and the fixing frame 23 together enclose a receiving space for receiving the support frame 21. Specifically, after the support frame 21 is erected, the opening of the first U-shaped bolt 241 is put on the support frame 21, and after the opposite ends of the first U-shaped bolt 241 pass through the fixing frame 23, the first U-shaped bolt 241 is locked by the first nut 242, so that the first U-shaped bolt 241 is fixed on the fixing frame 23. As the first nut 242 is continuously engaged, the support frame 21 and the fixing frame 23 can be pulled closer until the support frame 21 and the fixing frame 23 are fitted and locked, thereby reducing the shaking of the support frame 21. The support frame 21 is put on the fixing frame 23 by the first U-shaped bolt 241 to ensure the strength of the support frame 21.

[0068] In addition, the locking mechanism 24 may also be a bolt that passes through the supporting frame 21 and the fixing frame 23 in sequence and is locked, thereby achieving detachable locking of the supporting frame 21 and the fixing frame 23 .

[0069] The support device 2 in this embodiment further includes at least one threading tube 25 , the number of which corresponds to the number of instruments 3 installed on a support frame 21 , and the interior of the threading tube 25 is open and is used for threading the cable 31 of the instrument 3 .

[0070] The threading tube 25 can be a steel tube 254 or an explosion-proof flexible tube 253, and is used to protect the cable 31 of the instrument 3. The cable 31 of the instrument 3 passes through the threading tube 25 and the bridge 4 in sequence, and finally converges and connects to the junction box 5.

[0071] The threading tube 25 includes a plurality of pipe fittings 251 which are sequentially axially spliced ​​through flexible joints 252. At least one flexible joint 252 is located on the tank top platform 1. When the support frame 21 needs to rotate relative to the mounting platform 22, a flexible joint 252 located on the mounting platform 22 can be disconnected first to separate the pipe fittings 251 and avoid interference between the threading tube 25 and the tank top platform 1. When the support frame 21 needs to be directly disassembled from the mounting platform 22, a flexible joint 252 located on the mounting platform 22 can be disconnected first to separate the pipe fittings 251 and facilitate disassembly of the support frame 21.

[0072] In some embodiments, the pipe fittings 251 are all explosion-proof flexible pipes 253. Alternatively, the pipe fittings 251 are all steel pipes 254. In this embodiment, one pipe fitting 251 is an explosion-proof flexible pipe 253, and the other pipe fittings 251 are steel pipes 254. The axial ends of the explosion-proof flexible pipe 253 are connected between the instrument 3 and a steel pipe 254 through a flexible joint 252.

[0073] Figure 5 It is a structural diagram of the flexible joint 252.

[0074] Reference Figure 2 and Figure 5 The flexible joint 252 includes a first connecting pipe 2521, a second connecting pipe 2522, a nut 2523 and a sealing ring 2524. Between two adjacent pipes 251, the first connecting pipe 2521 is arranged on the end of one of the pipes 251, and the second connecting pipe 2522 is arranged on the end of the other pipe 251. The outer circumferences of the first connecting pipe 2521 and the second connecting pipe 2522 are both provided with external threads. The two adjacent pipes 251 are spliced ​​together so that a sealing gasket is sandwiched between the pipe surfaces of the first connecting pipe 2521 and the second connecting pipe 2522. The nut 2523 is pre-sleeved on the pipe 251 provided with the first connecting pipe 2521. By moving and engaging the nut 2523 with internal threads on the first connecting pipe 2521 and the second connecting pipe 2522, the detachable connection of the two adjacent pipes 251 is achieved. There are matching step surfaces between the nut 2523 and the first connecting pipe 2521 to prevent the nut 2523 from falling off the pipe 251 connected to the first connecting pipe 2521, ensuring that the first connecting pipe 2521 and the second connecting pipe 2522 can be engaged at the same time.

[0075] Furthermore, the threading tube 25 includes a laying section and an adjusting section which are connected in sequence and bent relative to each other. The laying section is located below the tank top platform 1 and extends horizontally. One axial end of the adjusting section is connected to the adjusting section, and the adjusting section passes through the mounting platform 22 upward, and the other axial end of the adjusting section is used to connect with the instrument 3. The laying section is located below the mounting platform 22 and the tank top platform 1, so that the cable 31 of the instrument 3 can be routed from the bottom of the tank top platform 1 to avoid obstructing the work of the staff.

[0076] In this embodiment, at least one flexible joint 252 is provided at the portion of the adjustment section located above the tank top platform 1. The connection position between the laying section and the adjustment section can be connected by an L-shaped pipe structure, and the laying section and the adjustment section can also be spliced ​​by multiple pipes 251. When the support frame 21 is in a vertical state, the instrument 3 is supported on the top of the support frame 21, and the cable 31 of the instrument 3 is passed through the threading tube 25. At this time, the adjustment section can also be in a vertical state.

[0077] Figure 6 The locking mechanism 26 is a structural diagram for locking the mounting block 28 and the threading tube 25 of the support frame 21 .

[0078] Reference Figure 1 and Figure 6 In this embodiment, the supporting device 2 further includes a plurality of locking mechanisms 26 .

[0079] The locking mechanism 26 is configured to lock the threading tube 25 and the support frame 21 to each other, and multiple locking mechanisms 26 are spaced apart along the axial extension direction of the threading tube 25. The locking mechanism 26 can lock the threading tube 25 passing through the tank top platform 1 with the support frame 21, reduce the shaking of the threading tube 25, and improve the installation stability of the instrument 3. Multiple locking mechanisms 26 further improve the positioning stability of the threading tube 25. Specifically, the locking mechanism 26 is connected between the adjustment section and the support frame 21, and the arrangement direction of the multiple locking mechanisms 26 is consistent with the extension direction of the adjustment section.

[0080] Furthermore, the locking mechanism 26 is configured to lock the threading tube 25 and the tank top platform 1 to each other, and a plurality of locking mechanisms 26 are spaced apart along the axial extension direction of the threading tube 25. The locking mechanism 26 can fix part of the threading tube 25 on the tank top platform 1, improve the positioning stability of the threading tube 25, and reduce the shaking of the threading tube 25. Specifically, the locking mechanism 26 is connected between the laying section and the tank top platform 1, and the arrangement direction of the plurality of locking mechanisms 26 is consistent with the extension direction of the laying section, and all extend horizontally. When the laying section and the adjustment section are connected as one, and the adjustment section moves to an upright state with the support frame 21, the locking mechanism 26 connected to the laying section can prevent the threading tube 25 from falling naturally, thereby improving the installation stability of the threading tube 25.

The locking mechanism 26 connects the laying section to the connecting block 27, and a plurality of locking mechanisms 26 are spaced apart along the axial extension direction of the laying section. The arrangement of the mounting block 28 and the connecting block 27 facilitates the connection of the locking mechanism 26. The supporting frame 21 is provided with a mounting block 28, and the locking mechanism 26 locks the threading tube 25 on the mounting block 28.

[0082] Specifically, the locking mechanism 26 includes a second U-shaped bolt 261 and a second nut 262. The outer circumferences of the opposite ends of the second U-shaped bolt 261 are provided with external threads. The opposite ends of the second U-shaped bolt 261 pass through the mounting block 28 or the connecting block 27. The second nut 262 threadably locks the part of the second U-shaped bolt 261 that passes through the mounting block 28 or the connecting block 27, thereby realizing a detachable connection between the second U-shaped bolt 261 and the support frame 21 or the tank top platform 1. The second U-shaped bolt 261 and the mounting block 28, or the second U-shaped bolt 261 and the connecting block 27, jointly enclose a accommodating space for accommodating the threading tube 25.

[0083] During installation, the instrument 3 is installed on the laid down support frame 21, and the cable 31 of the instrument 3 is inserted into the threading tube 25. The locking mechanism 26 locks the laying section of the threading tube 25 on the tank top platform 1, and the locking mechanism 26 locks the adjustment section of the threading tube 25 on the support frame 21. After the support frame 21 is erected on the installation platform 22, the support frame 21 is locked on the fixed frame 23 through the locking mechanism 24, and then the pipe fitting 251 between the laying section and the adjustment section is spliced ​​through the flexible joint 252 to form the threading tube 25 as a whole.
