[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example
[0031] Please see Figures 1-6The present invention provides the following technical solution: a fully liquid-contact stainless steel double-disc internal floating disk, comprising multiple fan-shaped double-layer floating disk blocks 1, each of which is equipped with a float 3, and a fixing column 4 is fixed on one side of one of the fan-shaped double-layer floating disk blocks 1.
[0032] The fan-shaped double-layer floating block 1 has mounting grooves 7 on both sides, and a pressing block 8 is placed on the fixing column 4. The outer wall of the pressing block 8 is fixed with a mounting plate 9 that cooperates with the mounting groove 7.
[0033] A screw 12 is threaded onto the fixed column 4, and an extrusion plate 13 is fixed to the top of the screw 12. A rocker plate 14 is fixed to the top of the extrusion plate 13.
[0034] The top of the extrusion block 8 is provided with a clearance hole 10 for the screw 12 to pass through, and a fixing groove 11 for the extrusion plate 13 to be inserted.
[0035] A limiting component 100 is provided on the extrusion block 8 and connected to the rocker plate 14 to prevent the screw 12 from rotating after tightening. The limiting component 100 includes a ratchet 101 fixed to the bottom of the rocker plate 14. A pawl 102 that meshes with the ratchet 101 is rotatably connected to the top of the extrusion block 8. A fixing plate 104 is fixed to the top of the extrusion block 8. A return spring 105 is provided on one side of the pawl 102. One end of the return spring 105 abuts against the fixing plate 104. In use, first, the fan-shaped double-layer floating disk block 1 with the fixing post 4 is placed in the designated position. Then, with the fixing post 4 as the axis, the adjacent fan-shaped double-layer floating disk blocks 1 are rotated and spliced to ensure that the mounting grooves 7 on the adjacent fan-shaped double-layer floating disk blocks 1 fit together to form a communication state. Then, the extrusion block 8 is placed on the fixing post 4 so that the mounting plate 9 is inserted into the mounting groove 7.
[0036] Then, rotate the rocker 14 clockwise to change the position of the pawl 102, preventing the pawl 102 from blocking the screw 12. At the same time, the return spring 105 is compressed. During this process, the screw 12 moves towards the bottom of the fixed post 4. Since the mounting plate 9 has been inserted into the mounting groove 7, the mounting plate 9 will not rotate when the screw 12 rotates. At this time, the screw 12 pushes the extrusion plate 13 to move towards the extrusion block 8 until the extrusion plate 13 is inserted into the fixed groove 11, thereby fixing the position of the extrusion block 8 and the mounting plate 9, and realizing a stable connection between adjacent fan-shaped double-layer floating disk blocks 1.
[0037] When the rocker 14 rotates clockwise to its limit position, the pawl 102 is reset under the action of the return spring 105 and engages with the ratchet 101 to prevent the rocker 14 from reversing and the screw 12 from loosening, thereby further improving the stability of the connection between adjacent fan-shaped double-layer floating blocks 1.
[0038] During disassembly, simply push the pawl 102 to one side, and the pawl 102 will disengage from the ratchet 101. At this time, rotate the rocker 14 counterclockwise. The rocker 14 will drive the screw 12 to rotate counterclockwise. The screw 12 will drive the extrusion plate 13 to move upward until the extrusion plate 13 is completely disengaged from the inside of the fixing groove 11. At this time, the extrusion block 8 and the mounting plate 9 can be removed from the inside of the mounting groove 7, which will facilitate the disassembly of the fan-shaped double-layer floating block 1.
[0039] Preferably, by Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the top of the pawl 102 is provided with a pushing block 103, the fixing plate 104 is provided with a guide hole 107, a connecting rod 106 is fixed on one side of the pawl 102, and one end of the connecting rod 106 passes through the guide hole 107. The reset spring 105 is sleeved on the connecting rod 106. The connecting rod 106 can increase the stability of the reset spring 105 and improve the stability of the reset spring 105 pushing the pawl 102 to reset. At the same time, the guide hole 107 can guide the connecting rod 106 to avoid the connecting rod 106 from deviating when moving, which further improves the stability of the movement of the pawl 102.
[0040] Preferably, by Figure 1 As shown in this embodiment, each of the multiple fan-shaped double-layer floating roof blocks 1 is provided with a sealing gasket 2. After the multiple fan-shaped double-layer floating roof blocks 1 are spliced together, the inside of the storage tank can be sealed. At this time, the sealing gasket 2 can improve the sealing between the fan-shaped double-layer floating roof blocks 1, avoid liquid leakage, and thus improve the practicality of the inner floating roof.
[0041] Preferably, by Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, a limiting groove 16 is provided on one side of each of the two mounting slots 7, and limiting plates 15 for insertion into the limiting groove 16 are fixed on both sides of the mounting plate 9. When the mounting plate 9 is inserted into the mounting slot 7, the limiting plate 15 will be inserted into the limiting groove 16, thereby further limiting the position of the mounting plate 9 and preventing the mounting plate 9 from shaking inside the mounting slot 7, thereby improving the stability of the connection between adjacent fan-shaped double-layer floating disk blocks 1.
[0042] Preferably, by Figure 1 , Figure 3 , Figure 5 and Figure 6As shown in this embodiment, a T-shaped plate 6 is provided on one side of the fan-shaped double-layer floating disk block 1, and a T-shaped groove 5 adapted to the T-shaped plate 6 of the adjacent floating disk block is provided on the other side; this can increase the stability of the connection between adjacent fan-shaped double-layer floating disk blocks 1, and at the same time, facilitate the assembly and disassembly of the fan-shaped double-layer floating disk blocks 1 by the staff. The cooperation of the T-shaped plate 6 and the T-shaped groove 5 can limit the position between adjacent fan-shaped double-layer floating disk blocks 1 and avoid misalignment.
[0043] Preferably, by Figure 1 As shown, in this embodiment, the outer wall of the rocker plate 14 is provided with anti-slip texture; this can increase the roughness of the surface of the rocker plate 14, thereby increasing the friction between the user's hand and the rocker plate 14, making it easier for the user to rotate the rocker plate 14, thus improving the convenience of using the inner floating plate.
[0044] Components not described in detail in this article are existing technologies.
[0045] The working principle and usage process of this utility model are as follows: Place the floating block 1 containing the fixed column 4 in the center of the storage tank and adjust the level.
[0046] With the fixed column 4 as the axis, align the mounting slots 7 of the adjacent fan-shaped double-layer floating blocks with the fixed column 4 in sequence, and insert the T-shaped plate 6 into the T-shaped slot 5 of the adjacent floating blocks to complete the initial splicing and positioning.
[0047] Insert the extrusion block 8 into the fixing post 4, so that the mounting plate 9 is embedded in the mounting groove 7, and the limiting plate 15 is simultaneously inserted into the limiting groove 16;
[0048] Rotate the rocker 14 clockwise, screw 12 into the internal threaded hole of the fixing column 4, and the extrusion plate 13 is gradually inserted into the fixing groove 11 of the extrusion block 8 until the extrusion block 8 is tightly attached to the splicing surface of the floating block.
[0049] The pawl 102 engages with the ratchet 101 under the action of the return spring 105, locking the rocker disc 14 to prevent reverse rotation.
[0050] When disassembly is required, simply push the push block 103 of the pawl 102 to one side to disengage the pawl 102 from the ratchet 101 and release the lock.
[0051] Rotate the rocker 14 counterclockwise, and the screw 12 will drive the extrusion plate 13 to move upward and disengage from the fixing groove 11;
[0052] Remove the extrusion block 8 and the mounting plate 9, and push the fan-shaped double-layer floating disk block 1 upward to separate the T-shaped plate 6 from the T-shaped groove 5. In this way, multiple adjacent fan-shaped double-layer floating disk blocks 1 can be separated one by one to achieve the disassembly of these fan-shaped double-layer floating disk blocks 1.
[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
