Description

Technical Field

[0001] The utility model relates to the technical field of sacrificial anodes, in particular to a sacrificial anode component. Background Art

[0002] A sacrificial anode refers to a metal used as an anode in electrochemical theory. The anode (metal) is gradually consumed as the current flows out. The outer plate corrosion protection of a ship is mostly achieved by immersing a sacrificial anode column in the water around the ship, and electrically connecting the sacrificial anode column to the outer plate of the ship through cables, which can effectively slow down the corrosion of the outer plate by seawater. When some sacrificial anode assemblies are used, the sacrificial anode column is first placed in the outer shell, and then the buckle plate and the outer shell are closed by bolts to fix the sacrificial anode column. The outer shell is then fixed to a designated position of the hull outer shell through a mounting seat, and then the connecting column on the outer shell is electrically connected to the ship, thereby protecting the ship from seawater corrosion. However, the sacrificial anode column is severely consumed due to long-term use and needs to be replaced regularly. When replacing, the bolts need to be removed and reinstalled one by one, which is a cumbersome operation. Utility Model Content

[0007] Furthermore, an arc seat is provided on the upper side of the lifting seat, and an arc slide is provided at both the front and rear ends of the arc seat through an arc telescopic column and spring three. Spring three is movably connected to the outer end of the adjacent arc telescopic column, and the lower end of the new sacrificial anode column is translated and limited by the arc slide. The arc slide can automatically reset after moving through the compression force of the spring.

[0008] Furthermore, the outer arc surface of the arc slide is provided with an arc guide seat, and the lower ends of the front and rear walls of the outer shell are provided with a fixed seat. The fixed seat and the arc guide seat are installed in coordination with each other, and the arc slide rotates to the left around the center of the lifting seat through contact and extrusion, gradually releasing the translation limit on the lower end of the new anode column.

[0009] Furthermore, a limit seat is provided on the bottom wall of the shell, and the limit seat is installed in cooperation with the lifting seat to limit the vertical downward position of the replaced new sacrificial anode column so that it is horizontally aligned with the old sacrificial anode column to facilitate subsequent replacement.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the sacrificial anode assembly has the following advantages:

[0013] When the sacrificial anode column is replaced, the bottom of the new sacrificial anode column is inserted into the upper side of the lifting seat. At this time, the arc surface of the arc sliding seat is used to limit the horizontal movement of the bottom of the sacrificial anode column.

When the lifting seat contacts the arc surface of the arc top seat, the arc top seat is pressed to move left, and the spring four elastically contracts. As the lifting seat moves downward, the rack plate slides down along the guide groove, and the rack plate is connected by meshing so that the gear drives the torsion spring to rotate, and the torsion force of the torsion spring gradually increases. During the downward movement of the lifting seat, when the arc guide seat moves to contact with the fixed seat, as the lifting seat continues to move downward, through the arc surface squeezing force of the arc guide seat, the telescopic end of the arc telescopic column and spring three contract, and the arc slide rotates counterclockwise along the outer edge of the lifting seat. The arc slide and the arc seat cooperate to reduce the moving limit contact surface of the bottom of the sacrificial anode column. When the lower side of the lifting seat moves to the upper side of the limit seat, At this time, the new sacrificial anode column is horizontally aligned with the old sacrificial anode column, and the arc-shaped slide seat moves to a position where the lower end of the new sacrificial anode column cannot be limited, and then the compression force of spring four causes the arc-shaped top seat to push the new sacrificial anode column horizontally to the right. At this time, the two arc-shaped extrusion seats on the left are compressed and opened longitudinally, so that the new sacrificial anode column enters between the arc-shaped extrusion seats. At the same time, through the same principle, the new sacrificial anode column uses the extrusion force to squeeze the old sacrificial anode column out through the unloading guide shell on the right, and then the lifting seat is moved up and reset by the torsion of the torsion spring, and the arc-shaped slide seat is elastically reset by the compression force of spring three, so that the device automatically returns to the initial state after replacing the sacrificial anode column, preparing for the next replacement of the sacrificial anode column. The sacrificial anode assembly can automatically replace the sacrificial anode column through elastic extrusion and meshing transmission, and the internal components of the device after the sacrificial anode column is replaced can automatically reset, and the sacrificial anode column can be replaced conveniently and quickly.

The arc extrusion seat 5 is evenly distributed, and the spring 14 is movably connected with the outer end of the adjacent telescopic column 13. The arc extrusion seat 5 is installed in cooperation with the lifting seat 13. The upper side of the lifting seat 13 is provided with an arc seat 14. The front and rear ends of the arc seat 14 are provided with an arc slide seat 17 through the arc telescopic column 15 and the spring three 16. The spring three 16 is movably connected with the outer end of the adjacent arc telescopic column 15. The outer arc surface of the arc slide seat 17 is provided with an arc guide seat 18. The lower ends of the front and rear walls of the shell 1 are provided with a fixed seat 19, and the fixed seat 19 is installed in cooperation with the arc guide seat 18. The bottom wall of the shell 1 is provided with a limit seat 20, and the limit seat 20 is installed in cooperation with the lifting seat 13. The bottom wall of the shell 1 is penetrated by a blanking guide shell 27, and the blanking guide shell 27 is connected to the arc The extrusion seat 5 is installed in cooperation. When the device is used, first fix it to the specified position of the hull through the mounting seat at the upper end of the device with bolts, and then the compression elastic force of the spring 2 7 makes the tightening seat 8 fit and contact with the sacrificial anode column 10. The sacrificial anode column 10 is connected to the external ship through the connecting column 9 via a wire, so as to protect the ship's hull from corrosion. When the sacrificial anode column 10 is replaced after long-term use, first open the threaded cover at the upper end of the device by rotation, and then insert the bottom of the new sacrificial anode column 10 into the upper side of the lifting seat 13. At this time, the bottom of the sacrificial anode column 10 is limited by the arc surface of the arc sliding seat 17 to avoid the sacrificial anode column 10 from elastic interference when inserted into the device, thereby misaligning and moving with the lifting seat 13. The arc centers of the telescopic ends and fixed ends of the seat 14, the arc-shaped slide seat 17 and the arc-shaped telescopic column 15 are vertically coincident with the center of the circle of the lifting seat 13. Then the staff applies downward pressure to the replaced sacrificial anode column 10, and the sacrificial anode column 10 drives the lifting seat 13 to move vertically downward, and the rack plate 12 slides down along the guide groove 11. The rack plate 12 is connected by meshing so that the gear 22 drives the torsion spring 23 to rotate, and the torsion force of the torsion spring 23 gradually increases. During the downward movement of the lifting seat 13, when the arc-shaped guide seat 18 moves to contact with the fixed seat 19, as the lifting seat 13 continues to move downward, the telescopic end of the arc-shaped telescopic column 15 and the spring three 16 are contracted through the arc surface squeezing force of the arc-shaped guide seat 18, and the arc-shaped slide seat 17 rotates counterclockwise along the outer edge of the lifting seat 13.The arc-shaped slide 17 cooperates with the arc-shaped seat 14 to gradually reduce the moving limit contact surface of the bottom of the sacrificial anode column 10. When the lower side of the lifting seat 13 moves to the upper side of the limit seat 20, the new sacrificial anode column 10 is horizontally aligned with the old sacrificial anode column 10, and the arc-shaped slide 17 moves to a position where the lower end of the new sacrificial anode column 10 cannot be limited. Then, through the compression elastic force of the spring four 25, the arc-shaped top seat 26 pushes the new sacrificial anode column 10 horizontally to the right. At this time, the two arc-shaped extrusion seats 5 on the left are compressed and opened longitudinally, and the corresponding telescopic ends of the telescopic columns 3 and the springs 4 contract, so that the new sacrificial anode column 10 enters between the arc-shaped extrusion seats 5. At the same time, through the same principle, the new sacrificial anode column 10 uses the extrusion force to push the old sacrificial anode column 10 through the right side. The material discharge guide shell 27 is squeezed out, and then the arc-shaped extrusion seat 5 is used to center and limit the new sacrificial anode column 10 through the compression elastic force of the spring 1 4. The outer edges of the tightening seat 8 and the base 2 are both arc-shaped chamfers, so that the sacrificial anode column 10 is conveniently guided when it contacts them. Then, the lifting seat 13 is moved up and reset through the torsion force of the torsion spring 23, and the arc-shaped slide seat 17 is elastically reset through the compression elastic force of the spring 3 16, so that the device automatically returns to the initial state after replacing the sacrificial anode column 10, so as to prepare for the next replacement of the sacrificial anode column 10. The sacrificial anode assembly can automatically replace the sacrificial anode column 10 through elastic extrusion and meshing transmission, and the internal components of the device after the sacrificial anode column 10 is replaced can be automatically reset, and the sacrificial anode column 10 is convenient and quick to replace;

[0021] Among them, the inner wall of the shell 1 is provided with an arc-shaped top seat 26 through the telescopic column three 24 and the spring four 25, and the spring four 25 is movably sleeved with the outer end of the telescopic column three 24. When the lifting seat 13 contacts the arc surface of the arc-shaped top seat 26, the arc-shaped top seat 26 is pressed and moved to the left, and the telescopic end of the telescopic column three 24 and the spring four 25 are elastically contracted. Then, the right end of the arc-shaped top seat 26 is squeezed and contacted with the outer left end of the replaced sacrificial anode column 10. The arc-shaped clamping of the sacrificial anode column 10 by the arc-shaped sliding seat 17 prevents the sacrificial anode column 10 from sliding relative to the lifting seat 13 after being pressed. After the new sacrificial anode column 10 releases the horizontal movement limit, the compression elastic force of the spring four 25 causes the arc-shaped top seat 26 to push the new sacrificial anode column 10 horizontally to the right, thereby providing horizontal thrust for the replacement of the sacrificial anode column 10.

[0022] The working principle of a sacrificial anode assembly provided by the utility model is as follows: when using the device, firstly, the mounting seat at the upper end of the device is fixed to the designated position of the hull with bolts, and then the compression elastic force of the spring 27 makes the tightening seat 8 fit and contact with the sacrificial anode column 10, and the sacrificial anode column 10 is connected to the external ship through the connecting column 9 via a wire, so as to protect the ship's hull from corrosion. When the sacrificial anode column 10 is replaced after a long period of use, first, the threaded cover at the upper end of the device is opened by rotation, and then the bottom of the new sacrificial anode column 10 is inserted into the upper side of the lifting seat 13, and at this time, the bottom of the sacrificial anode column 10 is limited by the arc surface of the arc slide 17, so as to avoid the sacrificial anode column 10 from elastically interfering with the lifting seat 13 when inserted into the interior of the device. Misalignment occurs, and the arc centers of the telescopic ends and fixed ends of the arc seat 14, the arc slide 17 and the arc telescopic column 15 are vertically coincident with the center of the circle of the lifting seat 13. Then the staff applies downward pressure to the replaced sacrificial anode column 10, and the sacrificial anode column 10 drives the lifting seat 13 to move vertically downward. When the lifting seat 13 contacts the arc surface of the arc top seat 26, the arc top seat 26 is pressed and moved to the left, and the telescopic end of the telescopic column three 24 and the spring four 25 are elastically contracted. Then the right end of the arc top seat 26 is squeezed and contacted with the outer left end of the replaced sacrificial anode column 10. The arc slide 17 is used to clamp the sacrificial anode column 10 in an arc shape to prevent the sacrificial anode column 10 from sliding relative to the lifting seat 13 after being pressed. At the same time, as the lifting seat 13 moves downward, the rack plate 12 moves along the guide The slot 11 slides down, and the rack plate 12 is meshedly connected so that the gear 22 drives the torsion spring 23 to rotate, and the torsion force of the torsion spring 23 gradually increases. During the downward movement of the lifting seat 13, when the arc guide seat 18 moves to contact with the fixed seat 19, as the lifting seat 13 continues to move downward, the arc surface extrusion force of the arc guide seat 18 causes the telescopic end of the arc telescopic column 15 and the spring three 16 to contract, and the arc slide 17 rotates counterclockwise along the outer edge of the lifting seat 13. The arc slide 17 cooperates with the arc seat 14 to gradually reduce the moving limit contact surface of the bottom of the sacrificial anode column 10. When the lower side of the lifting seat 13 moves to the upper side of the limit seat 20, the new sacrificial anode column 10 is horizontally aligned with the old sacrificial anode column 10, and the arc slide 17 moves to a point where it cannot contact the new one. The lower end of the sacrificial anode column 10 is limited, and then the compression force of the spring four 25 causes the arc-shaped top seat 26 to push the new sacrificial anode column 10 horizontally to the right. At this time, the two arc-shaped extrusion seats 5 on the left are compressed and opened longitudinally, and the corresponding telescopic ends of the telescopic column 3 and the spring one 4 are contracted, so that the new sacrificial anode column 10 enters between the arc-shaped extrusion seats 5. At the same time, through the same principle, the new sacrificial anode column 10 uses the extrusion force to squeeze the old sacrificial anode column 10 out through the unloading guide shell 27 on the right. Then, the compression force of the spring one 4 causes the arc-shaped extrusion seat 5 to center and limit the new sacrificial anode column 10. The outer edges of the tightening seat 8 and the base 2 are both arc-shaped chamfers, so as to facilitate the guidance of the sacrificial anode column 10 when it contacts them.Then, the lifting seat 13 is moved upward and reset by the torsion force of the torsion spring 23, and the arc-shaped slide seat 17 is elastically reset by the compression force of the spring 3 16, so that the device automatically returns to the initial state after replacing the sacrificial anode column 10, preparing for the next replacement of the sacrificial anode column 10.
