[0025] like Figures 1-4As shown, an inner wall curing device for a storage tank liner provided by an embodiment of the present invention will now be described. This inner wall curing device for a storage tank liner includes a liquid storage tank 1 containing a protective liquid. Support legs are fixedly installed around the bottom of the liquid storage tank 1. A support frame 2 is fixedly installed on the upper surface of the liquid storage tank 1, and a body 4, which is the inner wall of the storage tank, is placed on the surface of the support frame 2. The body 4 is the inner wall of the storage tank liner. An opening 3 is provided on the upper surface of the liquid storage tank 1 that cooperates with the body 4. The body 4 is placed upside down on the support frame 2 and corresponds to the opening 3. A curing mechanism 5 extending into the inner cavity of the body 4 is provided inside the liquid storage tank 1. The curing mechanism 5 includes a brushing component 51, a lifting component 52, and a rotating component 53. The brushing component 51 is located in a ring shape within the body liner. The body 4 has an inner cavity. The brushing assembly 51 is used to brush the inner annular sidewall of the body 4. The lifting assembly 52 is located between the liquid storage tank 1 and the body 4 and is connected to the brushing assembly 51. The lifting assembly 52 is used to adjust the height of the brushing assembly 51. The rotating assembly 53 is connected to the brushing assembly 51 and is used to control the brushing assembly 51 to move vertically while rotating horizontally. A blower assembly 6 is provided between the liquid storage tank 1 and the body 4. The blower assembly 6 is used to accelerate the airflow speed inside the body 4. The lifting assembly 52 and the blower assembly 6 are connected to a drive assembly 7.

[0026] In use, an appropriate amount of protective liquid is poured into the main body 4, and the protective liquid is applied to the inner bottom wall of the main body 4. Excess protective liquid in the main body 4 is poured out, and the main body 4 is placed upside down on the surface of the support frame 2. Initially, the lifting component 52 controls the brushing component 51 to be in the liquid storage tank 1. The brushing component 51 absorbs an appropriate amount of protective liquid. The driving component 7 and the lifting component 52 cooperate to control the brushing component 51 to move vertically upward and then into the inner cavity of the main body 4. The annular brushing component 51 can perform all-round brushing treatment on the annular inner sidewall of the main body 4. While the brushing component 51 moves vertically upward, the rotating component 53 controls the brushing component 51 to rotate in the horizontal direction, which can further improve the brushing effect on the inner sidewall of the main body 4. After the inner sidewall of the main body 4 is brushed, the brushing component 51 moves back into the liquid storage tank 1. The driving component 7 and the blower component 6 cooperate to accelerate the air flow speed in the inner cavity of the main body 4, thereby accelerating the curing of the protective liquid on the inner sidewall of the main body 4.

[0027] like Figure 1 , Figure 2 , Figure 4As shown, in a preferred embodiment of the present invention, the coating assembly 51 includes a fixing ring 511, and a coating sponge 513 is fixedly connected to the side of the fixing ring 511 facing the annular inner wall of the body 4. The coating sponge 513 has an annular structure. A liquid storage cavity 512 is opened inward on the top wall of the fixing ring 511. A connection hole 514 for connecting with the coating sponge 513 is opened on the side wall of the liquid storage cavity 512. The fixing ring 511 is connected to the lifting assembly 52.

[0028] The fixing ring 511 is located inside the liquid storage tank 1. The protective liquid in the liquid storage tank 1 flows into the liquid storage cavity 512. The lifting component 52 controls the fixing ring 511 to move towards the inner cavity of the body 4. The coating sponge 513 on the side wall of the fixing ring 511 contacts the inner side wall of the body 4. The coating sponge 513 evenly coats the protective liquid onto the inner side wall of the body 4. When the coating sponge 513 coats the inner side wall of the body 4 from bottom to top, the protective liquid contained in the liquid storage cavity 512 continuously flows into the coating sponge 513 through the connecting hole 514, which can continuously replenish the protective liquid to the coating sponge 513 and improve the coating effect of the coating sponge 513 on the inner side wall of the body 4.

[0029] like Figure 1 , Figure 3 , Figure 4 As shown, in a preferred embodiment of the present invention, the lifting assembly 52 includes a vertically upward threaded rod 521 rotatably mounted on the inner bottom wall of the liquid storage tank 1. A sliding block 523 is threadedly connected to the surface of the threaded rod 521. A limiting rod 522 located around the threaded rod 521 is fixedly mounted on the inner bottom wall of the liquid storage tank 1. The sliding block 523 is slidably connected to the limiting rod 522. Multiple sets of connecting rods 524 arranged in a ring are fixedly mounted on the side wall of the sliding block 523. The ends of the multiple sets of connecting rods 524 away from the sliding block 523 are jointly fixedly connected to a control ring 525. The side wall of the control ring 525 is rotatably connected to a fixed ring 511. The bottom end of the threaded rod 521 extends to the outside of the liquid storage tank 1 and is connected to the drive assembly 7.

[0030] In use, the drive assembly 7 controls the rotation of the threaded rod 521. The threaded rod 521 and the limiting rod 522 cooperate to push the sliding block 523 to move along the axis of the threaded rod 521. The sliding block 523 and the connecting rod 524 cooperate to drive the control ring 525 to move synchronously in the vertical direction. The control ring 525 drives the fixed ring 511 to move between the liquid storage tank 1 and the inner cavity of the body 4.

[0031] like Figure 1 , Figure 2As shown, in a preferred embodiment of the present invention, the rotating assembly 53 includes a horizontal plate 531 fixedly mounted on the side wall of a connecting rod 524. A first rotating rod 532 is rotatably mounted on the surface of the horizontal plate 531. The top end of the first rotating rod 532 extends upward from the horizontal plate 531 and is fixedly connected to a fixed gear disk 533. A gear ring 534 that meshes with the fixed gear disk 533 is fixedly mounted on the side wall of a fixed ring 511. The bottom end of the first rotating rod 532 extends downward from the horizontal plate 531 and is fixedly connected to a driven helical gear disk 535. A vertical plate 536 is fixedly mounted on the side wall of the connecting rod 524. A second rotating rod 537 is rotatably mounted on the surface of the vertical plate 536. One end of the second rotating rod 537 is fixedly mounted with an active helical gear disk 538 that meshes with the driven helical gear disk 535. The other end of the second rotating rod 537 is fixedly mounted with a control gear disk 539. A rack 530 that is vertically upward and meshes with the control gear disk 539 is fixedly mounted on the bottom wall of the liquid storage tank 1.

[0032] In use, the sliding block 523 and the connecting rod 524 move vertically, thereby driving the vertical plate 536 to move synchronously. The vertical plate 536 and the second rotating rod 537 cooperate to drive the control gear 539 to roll along the surface of the rack 530. The control gear 539 drives the second rotating rod 537 to rotate, thereby driving the active helical gear 538 to rotate. The active helical gear 538 drives the first rotating rod 532 to rotate, thereby driving the fixed gear 533 to rotate. The fixed gear 533 meshes with the gear ring 534, thereby driving the fixed ring 511 to rotate on the surface of the control ring 525. The fixed ring 511 drives the coating sponge 513 to rotate on the inner wall of the body 4, so that the protective liquid can be evenly coated on the inner wall of the body 4.

[0033] like Figure 1 As shown, in a preferred embodiment of the present invention, the blower assembly 6 includes a rotating rod 61 that is rotatably mounted on the bottom wall of the liquid storage tank 1 and extends vertically upward to the inner cavity of the body 4. The surface of the rotating rod 61 is provided with multiple sets of fan blades 62, and the rotating rod 61 is connected to the drive assembly 7.

[0034] After the coating sponge 513 finishes coating the inner wall of the body 4, the drive assembly 7 controls the rotating rod 61 to rotate, thereby driving the fan blade 62 to rotate in the inner cavity of the body 4. The fan blade 62 accelerates the air flow speed in the inner cavity of the body 4, thereby accelerating the curing of the protective liquid on the inner wall of the body 4.

[0035] like Figure 1As shown, in a preferred embodiment of the present invention, the drive assembly 7 includes a fixed frame 71 that is slidably mounted on the bottom wall of the liquid storage tank 1 in a horizontal direction. A motor 72 is fixedly mounted on the surface of the fixed frame 71. A transmission gear 73 is fixedly mounted on the output shaft of the motor 72. The bottom end of the threaded rod 521 extends to the outside of the liquid storage tank 1 and is fixedly mounted with a first rotating gear 74 that meshes with the transmission gear 73. The bottom end of the rotating rod 61 extends to the outside of the liquid storage tank 1 and is fixedly mounted with a second rotating gear 75 that meshes with the transmission gear 73. A positioning part 8 is provided on the surface of the fixed frame 71.

[0036] When it is necessary to coat the inner wall of the main body 4, the positioning part 8 adjusts the position of the fixing frame 71 so that the transmission gear 73 meshes with the first rotating gear 74. The motor 72 drives the transmission gear 73 to rotate. The transmission gear 73 meshes with the first rotating gear 74, thereby driving the threaded rod 521 to rotate. When it is necessary to dry and cure the inner wall of the main body 4, the positioning part 8 adjusts the position of the fixing frame 71 so that the transmission gear 73 meshes with the second rotating gear 75. The transmission gear 73 meshes with the second rotating gear 75, thereby driving the rotating rod 61 to rotate.

[0037] like Figure 1 As shown, in a preferred embodiment of the present invention, the positioning part 8 includes a through hole 81 on the surface of the fixing frame 71, and two sets of parallel threaded holes 82 are provided on the bottom wall of the liquid storage tank 1. A positioning screw 83 that cooperates with the threaded hole 82 is installed in the through hole 81. By inserting the positioning screw 83 into the threaded hole 82 at different positions, the position of the fixing frame 71 can be easily adjusted.

[0038] The working principle of this invention is as follows: An appropriate amount of protective liquid is poured into the body 4, which coats the inner bottom wall of the body 4. Excess protective liquid is then poured out, and the body 4 is placed upside down on the surface of the support frame 2. The positioning part 8 adjusts the position of the fixing frame 71 so that the transmission gear 73 meshes with the first rotating gear 74. The motor 72 drives the transmission gear 73 to rotate. The meshing of the transmission gear 73 with the first rotating gear 74 drives the threaded rod 521 to rotate. The threaded rod 521 cooperates with the limiting rod 522. The sliding block 523 is pushed to move along the axis of the threaded rod 521. The sliding block 523 and the connecting rod 524 cooperate to drive the control ring 525 to move synchronously in the vertical direction. The control ring 525 drives the fixed ring 511 to move between the liquid storage tank 1 and the inner cavity of the body 4. The fixed ring 511 is located in the liquid storage tank 1. The protective liquid in the liquid storage tank 1 flows into the liquid storage cavity 512. The fixed ring 511 moves towards the inner cavity of the body 4. The coating sponge 513 on the side wall of the fixed ring 511 contacts the inner side wall of the body 4. 13. The protective liquid is evenly applied to the inner wall of the body 4. When the application sponge 513 applies the protective liquid to the inner wall of the body 4 from bottom to top, the protective liquid contained in the storage cavity 512 continuously flows into the application sponge 513 through the connection hole 514, which can continuously replenish the protective liquid to the application sponge 513 and improve the application effect of the application sponge 513 on the inner wall of the body 4. The sliding block 523 and the connecting rod 524 move in the vertical direction, thereby driving the vertical plate 536 to move synchronously. The vertical plate 536 and the second rotating rod 537 cooperate with each other to bring The control gear 539 rolls along the surface of the rack 530. The control gear 539 drives the second rotating rod 537 to rotate, which in turn drives the active helical gear 538 to rotate. The active helical gear 538 drives the first rotating rod 532 to rotate, which in turn drives the fixed gear 533 to rotate. The fixed gear 533 meshes with the gear ring 534, which in turn drives the fixed ring 511 to rotate on the surface of the control ring 525. The fixed ring 511 drives the coating sponge 513 to rotate on the inner wall of the body 4, so that the protective liquid can be evenly applied to the inner wall of the body 4. When it is necessary to dry and cure the inner wall of the body 4, the positioning part 8 adjusts the position of the fixing frame 71 so that the transmission gear 73 meshes with the second rotating gear 75. The meshing of the transmission gear 73 with the second rotating gear 75 drives the rotating rod 61 to rotate. The rotation of the rotating rod 61 drives the fan blade 62 to rotate in the inner cavity of the body 4. The fan blade 62 accelerates the air flow speed in the inner cavity of the body 4, which in turn accelerates the curing of the protective liquid on the inner wall of the body 4.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application.
