DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 - Figure 5As shown, a ring plate hydraulic lifting device for a water storage tank for seawater desalination includes a ring plate body 1 and multiple groups of hydraulic devices 21. A fixing ring 20 is welded and fixed on the inner wall of the ring plate body 1. A connecting mechanism is arranged inside the fixing ring 20. The connecting mechanism includes two groups of movable grooves 27. The movable grooves 27 are rectangular in design. The movable grooves 27 are arranged inside the fixing ring 20. A spring 26 is welded and fixed on the inner wall of the movable groove 27. The spring 26 is welded and fixed to an insert block 25. The insert block 25 is trapezoidal in design and slides in the movable groove 27. The insert block 25 is engaged in the inside of a slot 23. The slot 23 is arranged on the left and right sides of a fixing plate 22. The bottom end of the fixing plate 22 is fixed to the hydraulic device 21 by welding. The fixing plate 22 is inserted in the inside of a fixing slot 24. The fixing slot 24 is arranged at the bottom end of the fixing ring 20.

[0024] When working, a hydraulic lifting device for the tank inversion method in the above technology lifts the tank wall, that is, the inner wall of the annular plate, of the tank through multiple sets of lifting equipment, and the lifting equipment generally needs to be fixed to the inner wall of the annular plate by welding. It is time-consuming to install and disassemble the lifting equipment. The structural design of the connecting mechanism realizes the function of facilitating the installation of the hydraulic device 21 and the removal of the hydraulic device 21 from the annular plate body 1. When the hydraulic device 21 is to be installed, first press the plug block 25 to push it into the movable groove 27 to ensure that the plug block 25 will not abut against the fixed plate 22 when the fixed plate 22 is inserted into the fixed groove 24, and then the fixed plate 22 on the top of the hydraulic device 21 is fixed. The fixed plate 22 is inserted into the fixed groove 24. When the insert block 25 is aligned with the slot 23, the insert block 25 will be automatically pushed into the slot 23 and engaged with the slot 23 under the action of the spring 26. At this time, when the hydraulic device 21 normally lifts the fixed plate 22, the fixed plate 22 can push the fixed ring 20 to move upward and then push the entire annular plate body 1 to lift. When the hydraulic device 21 is to be removed, it only needs to be moved away from the fixed ring 20. Since the insert block 25 is designed in a trapezoidal shape, the slot 23 can push the insert block 25 to move until the insert block 25 is no longer engaged with the slot 23, and the fixed plate 22 can be smoothly taken out of the fixed groove 24, thereby completing the disassembly operation of the hydraulic device 21.

[0025] Furthermore, four sets of sliders 35 are welded and fixed on the fixing plate 22, and the sliders 35 are inserted in the slide grooves 36, and the slide grooves 36 are opened on the inner wall of the fixing groove 24;

[0026] During operation, through the structural design of the slider 35 and the slide groove 36, when the fixed plate 22 is inserted into the fixed groove 24, the abutment between the slider 35 and the inner wall of the slide groove 36 can ensure that the fixed plate 22 will not rotate in the fixed groove 24, so as to facilitate the connection between the fixed ring 20 and the hydraulic device 21.

[0027] Furthermore, two groups of positioning columns 33 are welded and fixed to the top of the fixing plate 22. The top of the positioning column 33 passes through the positioning groove 34. The positioning groove 34 is provided at the top of the fixing ring 20. There are four groups of positioning grooves 34.

[0028] During operation, the positioning posts 33 are inserted into the positioning grooves 34 . Since the two groups of positioning posts 33 are on the same diagonal line, the positioning posts 33 are aligned with any two groups of positioning grooves 34 and inserted therein to ensure that the slots 23 and the inserts 25 are aligned, so as to facilitate the installation of the hydraulic device 21 .

[0029] Furthermore, a through slot 28 is formed on the fixed ring 20, and the through slot 28 is connected to the inside of the movable slot 27, and a connecting rod 29 is welded and fixed to the top of the insert block 25;

[0030] During operation, the through slot 28 is connected to the interior of the movable slot 27, and a connecting rod 29 slides in the through slot 28. The connecting rod 29 is arranged on the outside so that the engagement between the slot 23 and the insert block 25 can be released by pushing the connecting rod 29 to both sides, so as to facilitate the disassembly of the hydraulic device 21.

[0031] Furthermore, the connecting rod 29 is designed in an L shape, and the connecting rod 29 is slidably connected to the long slot 30, and the long slot 30 is opened at the top of the fixing ring 20;

[0032] When working, the connecting rod 29 is designed in an L shape as a whole, and the connecting rod 29 slides in the long groove 30. The abutment between the inner wall of the long groove 30 and the connecting rod 29 can ensure the normal movement of the connecting rod 29, and at the same time, the connecting rod 29 can be protected to prevent the connecting rod 29 from being bent or broken due to external collision or impact.

[0033] Furthermore, a semicircular block 31 is welded and fixed to the top of the connecting rod 29, and the semicircular block 31 is threadedly connected to the fixing sleeve 32;

[0034] During operation, a semicircular block 31 is fixed on the connecting rod 29 , and threads are provided on the inner walls of the semicircular block 31 and the fixing sleeve 32 . The fixing sleeve 32 and the two groups of semicircular blocks 31 are connected by threads to ensure that the insert block 25 can maintain the engagement and fixation with the slot 23 .

[0035] Working principle: A hydraulic lifting device used for the tank inversion method in the prior art uses multiple sets of jacking equipment to lift the tank wall, that is, the inner wall of the annular plate of the tank, and the jacking equipment generally needs to be fixed to the inner wall of the annular plate by welding. It is time-consuming to install and disassemble the jacking equipment. In this case, a hydraulic lifting device for the annular plate of a water storage tank for seawater desalination is designed with a connecting mechanism to facilitate the installation of the hydraulic device 21 and the removal of the hydraulic device 21 from the annular plate body 1. When the hydraulic device 21 is to be installed, first press the plug block 25 to push it into the inside of the movable groove 27 to ensure that the plug block 25 will not abut against the fixed plate 22 when the fixed plate 22 is inserted into the fixed groove 24, and then Insert the fixing plate 22 on the top of the hydraulic device 21 into the fixing groove 24. When the insert block 25 is aligned with the slot 23, the insert block 25 will be automatically pushed into the slot 23 and engaged with the slot 23 under the action of the spring 26. At this time, when the hydraulic device 21 normally lifts the fixing plate 22, the fixing plate 22 can push the fixing ring 20 to move upward and then push the entire annular plate body 1 to lift. When the hydraulic device 21 is to be removed, it is only necessary to move the hydraulic device 21 away from the fixing ring 20. Since the insert block 25 is trapezoidal in design, the slot 23 can push the insert block 25 to move until the insert block 25 is no longer engaged with the slot 23, and the fixing plate 22 can be smoothly taken out of the fixing groove 24, thereby completing the disassembly operation of the hydraulic device 21.
