DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 A steel-lined plastic storage tank includes a tank body 1 and a base 3. The tank body 1 is installed above the base 3 through supporting legs 2. A mounting frame 7 is provided on the base 3 through a mounting groove. A protective pad 17 is provided on the surface of the mounting frame 7 that contacts the tank body 1. The protective pad 17 prevents the mounting frame 7 from shaking during installation and colliding with the outer wall of the tank body 1 to cause damage.

[0025] A screw rod 9 is provided on the mounting frame 7 through the driving motor 6, a nut 10 is threadedly sleeved on the screw 9, a connecting plate 8 is provided on the nut 10 through an insertion mechanism, an outlet pipe 4 is provided on the tank body 1, a pipe cover 5 is installed on the connecting plate 8, a vertical opening 13 is provided on the mounting frame 7, and the connecting plate 8 cooperates with the vertical opening 13 through an anti-slip mechanism, a cavity is provided inside the mounting frame 7, a movable block 18 is provided in the cavity through a first elastic mechanism, a sliding rod 20 is provided in the cavity, two sliding sleeves 19 are slidingly sleeved on the sliding rod 20 through a second elastic mechanism, and positioning blocks 16 are provided on the two sliding sleeves 19, positioning grooves corresponding to the positioning blocks 16 are provided on the inner walls on both sides of the mounting groove, a through rod 15 extending into the opening on the mounting frame 7 is provided on the movable block 18, and the outer walls of the movable block 18 and the positioning block 16 are both inclined.

[0026] The plug-in mechanism includes an insert block arranged on the outer wall of the nut 10, and a slot corresponding to the insert block is provided on the surface of the connecting plate 8 that contacts the nut 10. The insert block and the slot are not shown schematically in the figure. The insert block is a rectangular block welded on the outer wall of the nut 10, and the slot is arranged corresponding to the insert block. When the insert block is inserted into the slot, the nut 10 moves up and down to drive the connecting plate 8 to move up and down synchronously.

[0027] The anti-slip mechanism includes an anti-slip rod 12 connected to the connecting plate 8. The anti-slip rod 12 is L-shaped in a top view. The mounting frame 7 is provided with a disassembly and assembly port 14 that cooperates with the anti-slip rod 12 and is connected to the vertical port 13. With the anti-slip rod 12 being in the vertical port 13, the lateral limitation of the connecting plate 8 is achieved, thereby preventing the connecting plate 8 from being separated from the nut 10, thereby preventing the plug block from being separated from the slot.

[0028] The first elastic mechanism includes a vertical spring arranged in the cavity, and the two ends of the vertical spring are elastically connected to the outer wall of the movable block 18 and the inner wall of the cavity respectively. The vertical spring is sleeved on the outside of the through rod 15. The elastic potential energy provided by the above vertical spring ensures the stability of the position of the movable block 18 in the cavity, thereby realizing the extrusion operation of the two positioning blocks 16.

[0029] The second elastic mechanism includes a transverse spring sleeved on the outside of the slide rod 20, and the two ends of the transverse spring are elastically connected to the outer walls of the two sliding sleeves 19 respectively. The above-mentioned transverse spring realizes the dragging operation of the two sliding sleeves 19, and can drive the positioning block 16 to move away from the positioning groove on the inner wall of the installation groove after the movable block 18 moves up to release the squeezing of the positioning block 16.

[0030] A baffle is provided at the upper end of the through rod 15, and the baffle is arranged corresponding to the anti-slip rod 12. With the help of the baffle, when the anti-slip rod 12 follows the nut 10 and other components to rise, the through rod 15 can be driven to rise synchronously.

[0031] A limiting rod 11 is provided on the mounting frame 7 , and the limiting rod 11 slides through the nut 10 . The limiting rod 11 is arranged parallel to the screw rod 9 , which realizes the limiting of the nut 10 assembly and effectively prevents it from rotating with the screw rod 9 .

[0032] When the utility model is used, when the outlet pipe 4 needs to be opened, the pipe cover 5 needs to be pulled out, and the driving motor 6 is started to drive the screw 9 to rotate. When the screw 9 rotates, the nut 10 threadedly mounted thereon drives the pipe cover 5 to rise and separate from the outlet pipe 4 with the help of the connecting plate 8.

[0033] As the screw rod 9 continues to rotate, the connecting plate 8 drives the anti-slip rod 12 assembly to continue to rise, and then the upper end surface of the anti-slip rod 12 contacts the bottom wall of the baffle at the end of the through rod 15, and finally the anti-slip rod 12 drives the through rod 15 to rise with the help of the above-mentioned baffle, and the through rod 15 drives the movable block 18 to rise in the cavity. At this time, the positioning block 16 moves under the action of the transverse spring, and the two positioning blocks 16 move and approach and disengage from the positioning groove on the inner wall of the mounting groove on the upper end surface of the base 3, and then the fixed installation of the mounting frame 7 relative to the base 3 is released, and the mounting frame 7 and other components can be disassembled, which is not only convenient for the inspection and maintenance of components such as the drive motor 6, but also convenient for the inspection and maintenance of the pipe cover 5 (for example, replacing the sealing ring provided thereon, etc.).

[0034] In this solution, after the mounting frame 7 and other components are disassembled, the connecting plate 8 and the pipe cover 5 can also be disassembled. The screw 9 needs to be rotated to drive the connecting plate 8 to descend with the help of the nut 10. As the descent continues, the anti-detachment rod 12 eventually descends to correspond to the disassembly opening 14. At this time, the connecting plate 8 can be disengaged from the nut 10 by moving it horizontally. After multiple components are disassembled, it is easier to inspect and maintain because there are no other components installed next to them to cause obstacles.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
