Detailed implementation manners

[0032] The following further describes the present application in detail with reference to the Figures 1-6 accompanying drawings.

[0033] Embodiment 1:

[0034] The embodiment of the present application discloses a hinge-type sacrificial anode 2 small sleeve.

[0035] Referring to Figure 1 , a hinge-type sacrificial anode 2 small sleeve is arranged on the pipe pile 5, and includes two connecting pieces 1, a plurality of sacrificial anodes 2, a plurality of positioning columns 3 and a plurality of fastening structures. The connecting piece 1 includes two semi-rings 11 and a plurality of connecting rods 12 for connecting the two semi-rings 11. The plurality of sacrificial anodes 2 are installed on each connecting rod 12; the semi-rings 11 of the two connecting pieces 1 are hinged to each other.

[0036] A plurality of positioning frames 13 are arranged on one side of one semi-ring 11 away from the connecting rod 12. All the positioning columns 3 are embedded in the pipe pile 5 and are arranged at intervals along the outer peripheral wall of the pipe pile 5. When the two connecting pieces 1 are wrapped around the outer wall of the pipe pile 5, all the positioning frames 13 are respectively inserted into each positioning column 3 to complete the preliminary positioning of the two connecting pieces 1 and reduce the situation that the connecting piece 1 is disengaged from the outer wall of the pipe pile 5 during use.

[0037] Referring to Figure 2The fastening structure is installed on the side of the other half ring 11 away from the connecting rod 12. In this embodiment, the fastening structure includes a mounting plate 41 and a bolt 42, and the bolt 42 has a second threaded groove; the mounting plate 41 is welded to the half ring 11, and is provided with threaded holes 411 penetrating through the opposite side walls of the mounting plate 41; a plurality of positioning blocks 51 are pre-embedded in the outer wall of the pipe pile 5, and all the positioning blocks 51 are arranged at intervals along the outer peripheral wall of the pipe pile 5, and the positioning blocks 51 are provided with all first threaded grooves 52.

[0038] When the two connecting plates are wrapped around the outer wall of the pipe pile 5, there is a gap between the mounting plate 41 and the positioning block 51, and the threaded hole 411 of the mounting plate 41 is arranged opposite to the first thread groove 52 of the positioning block 51. At this time, the second thread groove of the bolt 42 cooperates with the inner wall of the threaded hole 411 and the first thread groove 52.

[0039] The implementation principle of Example 1 of the present application is:

[0040] The two connectors 1 are hingedly connected so that they can be easily sleeved on the outer wall of the pipe pile 5 and fixed by a fastening structure. This design not only simplifies the installation process, but also facilitates the disassembly and replacement of the sacrificial anode 2 when necessary, thereby improving the convenience of maintenance.

[0041] Embodiment 2:

[0042] The embodiment of the present application discloses a hinged sacrificial anode 2 small sleeve.

[0043] Reference Figure 3 and Figure 4 , the difference between the embodiment 2 of the present application and the embodiment 1 is that: an extension part 61 is welded on the side of the installation piece 41 close to the positioning block 51, and an elastic piece 6 is integrally formed on one side of the extension part 61, and the extension direction of the elastic piece 6 is staggered with the extension direction of the extension part 61; the side of the elastic piece 6 away from the extension part 61 is used for plugging and matching with the second thread groove of the bolt 42. The inclined elastic piece 6 can provide a force for the bolt 42 toward the first thread groove 52, reduce the situation that the bolt 42 is separated from the first thread groove 52, and increase the stability of the connection member 1 fixed to the outer wall of the pipe pile 5.

[0044] Reference Figure 3 A positioning groove 31 for the positioning frame 13 to be inserted into the upper wall of the positioning column 3 is opened. When the two connecting members 1 are sleeved on the outer wall of the pipe pile 5, the positioning column 3 is inserted into the positioning frame 13. At this time, one side of the positioning frame 13 is inserted into the positioning groove 31, so that the positions of the two connecting members 1 can be temporarily fixed. At this time, the connecting member 1 and the pipe pile 5 are connected by the fastening structure.

[0045] Embodiment 3:

[0046] The embodiment of the present application discloses a hinged sacrificial anode 2 small sleeve.

[0047] Refer to Figure 5 and Figure 6 In Embodiment 3 of the present application, the difference from Embodiment 1 is that the fastening structure includes a mounting plate 43, two mounting rods 44 and two anti - detachment components 45. The two mounting rods 44 are respectively fixed to one end of the two semi - rings 11 away from their hinge points; the mounting plate 43 is provided with mounting holes 431 for inserting the two mounting rods 44, and the anti - detachment components 45 are used to connect the mounting rods 44 and the inner wall of the mounting holes 431.

[0048] The anti - detachment component 45 includes an anti - detachment block 46, a spring 47 and an unlocking member 48. An activity groove 441 is formed on the outer wall of the mounting rod 44, the anti - detachment block 46 is movably installed in the activity groove 441, and an anti - detachment groove 432 for inserting the anti - detachment block 46 is formed on the inner wall of the mounting hole 431; a second guiding surface is provided on one side of the anti - detachment block 46 close to the semi - ring 11, and the distance between the second guiding surface and the semi - ring 11 gradually increases from the side close to the activity groove 441 to the side far from the activity groove 441. The second guiding surface is used to guide the anti - detachment block 46 into the activity groove 441.

[0049] The two ends of the spring 47 are respectively connected to the anti - detachment block 46 and the inner wall of the activity groove 441. The elastic force of the spring 47 is used to drive the anti - detachment block 46 to move towards the side far from the inside of the activity groove 441; the elastic force of the spring 47 can maintain the stability of the anti - detachment block 46 inserted into the anti - detachment groove 432, thereby reducing the possibility of the mounting plate 43 detaching from the connection with the mounting rod 44.

[0050] The unlocking member 48 includes an unlocking rod 481 and two unlocking blocks 482. The two unlocking blocks 482 respectively slide in the two anti - detachment grooves 432; a first guiding surface is provided on one side of the two unlocking blocks 482 close to each other, and an unlocking surface is provided on one side of the two unlocking blocks 482 far from each other. The distance between the first guiding surface and the unlocking surface gradually decreases from the side close to the semi - ring 11 to the side far from the semi - ring 11. The first guiding surface is used to guide the unlocking block 482 to move towards the side of the activity block.

[0051] Refer to Figure 5 An unlocking groove 433 communicating with the two anti - detachment grooves 432 is formed on the upper wall of the mounting plate 43. A detachable rubber block 49 is inserted into the unlocking groove 433. The setting of the rubber block 49 can reduce the situation of foreign objects entering the unlocking groove 433 from the outside; when the two anti - detachment blocks 46 are both inserted into the two anti - detachment grooves 432, the two unlocking blocks 482 are in contact with each other.

[0052] The implementation principle of Embodiment 3 of the present application is as follows:

[0053] After two connecting members 1 are sleeved on the outer wall of the pipe pile 5, two mounting rods 44 are simultaneously inserted into two mounting holes 431 of the mounting plate 43. At this time, two anti-disengagement blocks 46 are respectively inserted into two anti-disengagement grooves 432. When it is necessary to remove the mounting plate 43 from the two mounting rods 44 to replace the connecting member 1, the rubber block 49 is removed and the unlocking rod 481 is inserted into the unlocking groove 433, and the unlocking rod 481 is inserted into the unlocking groove 433 and moved toward the side of the unlocking block 482. At this time, the unlocking rod 481 abuts against the guiding surface of the unlocking block 482, and the unlocking block 482 moves toward the side of the moving groove 441 under the guidance of the guiding surface and pushes the anti-disengagement block 46 back into the moving groove 441 again, thereby canceling the connection between the mounting rod 44 and the mounting plate 43.

[0054] The above is the preferred embodiment of the present application. It does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
