DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] Please refer to Figure 1 - Figure 5As shown, a kind of inner coating casing well's sacrificial anode protection device, including pipeline 1, pipeline 1 outside is provided with sacrificial anode cover 2, two groups of fixed mechanism are provided in sacrificial anode cover 2 inside, fixed mechanism includes long slot 3, long slot 3 is set up in one side in the inside of sacrificial anode cover 2, long slot 3 bottom is provided with transverse slot 4, one end of transverse slot 4 is provided with clamping groove 5, one end of clamping groove 5 is provided with moving slot 6, screw rod 7 is provided in moving slot 6 inside, one end of screw rod 7 is fixedly connected with first bevel gear 8, first bevel gear 8 is rotatably connected with one end of moving slot 6, moving block 9 is threadedly connected on the outside of screw rod 7;

[0023] When working, after the clamping block 10 outside the pipeline 1 is aligned with the long slot 3, the sacrificial anode cover 2 is moved and appropriately rotated to enter the long slot 3, the transverse slot 4 and the clamping groove 5, at this time, the rotating rotating column 14 drives the second bevel gear 13 to rotate, thereby driving the first bevel gear 8 and the screw rod 7 to rotate, and further driving the moving block 9 to move to abut against the clamping block 10 to fix it in the clamping groove 5, at this time, the sacrificial anode cover 2 cannot move outside the pipeline 1, thereby completing the fixing function of the sacrificial anode cover 2, solving the problem that the sacrificial anode protection device of the inner coating casing well is installed in two groups and then fixed outside the pipeline 1, instead of being an integral sacrificial anode protection device, which needs a certain time for installation when installing and dismounting the sacrificial anode protection device, resulting in low installation and dismounting efficiency.

[0024] Further, as shown in the drawings, Figure 2 The clamping groove 5 is provided with the clamping block 10, and the clamping block 10 is fixedly connected with the outside of the pipeline 1.

[0025] When working, the clamping block 10 is abutted by the moving block 9 after entering the clamping groove 5, at this time, the clamping block 10 cannot move inside the clamping groove 5, and since the clamping block 10 is fixedly connected with the pipeline 1, the pipeline 1 and the sacrificial anode cover 2 cannot move relatively, thereby completing the fixing of the sacrificial anode cover 2.

[0026] Further, as shown in the drawings, Figure 4 The cross-sectional dimensions of the long slot 3, the transverse slot 4, the clamping groove 5, the moving slot 6 and the clamping block 10 are the same, the transverse slot 4, the clamping groove 5 and the moving slot 6 are through, and the length of the moving block 9 is greater than the length of the clamping groove 5.

[0027] When working, the cross-sectional dimensions of the long slot 3, the transverse slot 4, the clamping groove 5, the moving slot 6 and the clamping block 10 are the same, so the clamping block 10 can smoothly enter the long slot 3, the transverse slot 4 and the clamping groove 5, and since the length of the moving block 9 is greater than the length of the clamping groove 5, the moving block 9 will be hindered by the clamping groove 5 when moving, and cannot be separated from the screw rod 7, thereby preventing the moving block 9 from being separated from the screw rod 7.

[0028] Further, as shown in the drawings, Figure 5As shown, two sets of guide rods 11 are fixedly connected to one end of the moving groove 6, and one end of the guide rod 11 passes through the moving block 9.

[0029] During operation, the rotation of screw 7 will cause the moving block 9 to have the same rotation tendency. The guide rod 11 can resist the rotation tendency of the moving block 9. Because of the threaded connection between the moving block 9 and screw 7, the moving block 9 can move on screw 7 as screw 7 rotates.

[0030] Furthermore, such as Figure 5 As shown, a stop post 12 is fixedly connected to the outside of the screw 7 near the first helical gear 8. A second helical gear 13 is provided at one end of the moving groove 6 near the first helical gear 8. The second helical gear 13 is rotatably connected to the moving groove 6 and meshes with the first helical gear 8. Two sets of rotating posts 14 are provided on the outside of the sacrificial anode sleeve 2. One end of the rotating post 14 passes through the sacrificial anode sleeve 2 and is fixedly connected to the second helical gear 13.

[0031] During operation, if the rotating column 14 directly penetrates the sacrificial anode sleeve 2 and is fixedly connected to one end of the screw 7, then the rotating column 14 would be located at both ends of the sacrificial anode sleeve 2. In this case, the rotating column 14 would be too close to the pipe 1, making it inconvenient to rotate. In order to allow the rotating column 14, which controls the rotation of the screw 7, to be installed on the outside of the sacrificial anode sleeve 2 for easy rotation, a second helical gear 13 is set to mesh with the first helical gear 8, which is fixedly connected to the screw 7, and the second helical gear 13 is rotatably connected to the top of the moving groove 6. In this way, the rotating column 14 can be located on the outside of the sacrificial anode sleeve 2 and fixedly connected to the second helical gear 13 through the sacrificial anode sleeve 2. Rotating the rotating column 14 will drive the second helical gear 13 to rotate, and through the meshing characteristics, it will drive the first helical gear 8 and the screw 7 to rotate.

[0032] Furthermore, such as Figure 2 As shown, a leak-proof pad 15 is provided on the outer side of one end of the pipe 1, and the leak-proof pad 15 is fixedly connected to the pipe 1.

[0033] During operation, the leak-proof gasket 15 can prevent leakage when the pipe 1 is connected to the device.

[0034] Working principle: When the sacrificial anode sleeve 2 needs to be installed, after aligning the locking block 10 on the outside of the pipe 1 with the long groove 3, the sacrificial anode sleeve 2 is moved and rotated so that the locking block 10 enters the slot 5 and the transverse groove 4. Then, the sacrificial anode sleeve 2 is pulled outward so that the locking block 10 enters the slot 5. At this time, the rotating column 14 drives the second helical gear 13 to rotate, which in turn drives the first helical gear 8 and the screw 7 to rotate, which in turn drives the moving block 9 to move to abut against the locking block 10 and fix it in the slot 5. At this time, the sacrificial anode sleeve 2 cannot move on the outside of the pipe 1. Since the locking block 10 is fixedly connected to the pipe 1, the pipe 1 and the sacrificial anode sleeve 2 cannot move relative to each other, thus completing the fixation of the sacrificial anode sleeve 2.

[0035] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
