A sliding groove is provided on the inner wall at the top end of the limit groove, and a fixing pin is slidably connected inside the sliding groove, and the bottom end of the fixing pin is movably connected to the rescue rod.

[0008] As an optional solution of the technical solution of the present application, the inner wall of the top end of the slide groove is rotatably connected to a threaded rod through a bearing, and a knob is fixedly installed on the top end of the threaded rod.

[0009] As an optional solution of the technical solution of the present application, a connecting groove is vertically opened in the middle of the upper surface of the fixing pin, and the connecting groove is spirally connected to the threaded rod.

[0010] As an optional solution of the technical solution of the present application, an outer side of one end of the rescue rod is provided with an external thread, and the other end of the rescue rod is provided with an internal thread, and two adjacent groups of rescue rods are spirally connected by the external thread and the internal thread.

[0011] As an optional solution of the technical solution of the present application, connecting sleeves are fixedly installed on the upper and lower ends of both sides of the raised fence, and the two ends of the raised fence are movably connected to the connecting sleeves on the outside of the column. The raised fence and the column are fixedly connected by bolts passing through the connecting sleeves.

[0012] As an optional solution of the technical solution of the present application, the size of the fixing pin matches the size of the sliding groove, and the size of the limiting groove matches the size of the rescue rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: through the combination of the column, the connecting sleeve and the heightening railing, the dam can be raised and protected; through the combination of the knob, the threaded rod, the slide groove, the fixed pin and the connecting groove, the rotating knob can drive the fixed pin to move upward and be retracted into the slide groove, thereby releasing the lock on the rescue rod, making it convenient to remove the rescue rod from the limit groove; through the external and internal threads at both ends of the rescue rod, multiple groups of rescue rods can be conveniently spliced ​​and lengthened, thereby further being able to rescue people who fall into the water.

[0018] See also Figure 1-Figure 2 The utility model provides a technical solution: a dam heightening structure, including a column 1 and a heightening fence 11, the heightening fence 11 is fixedly connected between two adjacent groups of columns 1, and also includes a limiting groove 12 and a rescue rod 13. The upper end of the column 1 away from the water surface is provided with a limiting groove 12, the rescue rod 13 is movably connected to the limiting groove 12, a slide groove 14 is provided on the top inner wall of the limiting groove 12, a fixing pin 15 is slidably connected inside the slide groove 14, the bottom end of the fixing pin 15 is movably connected to the rescue rod 13, the top inner wall of the slide groove 14 is rotatably connected with a threaded rod 16 through a bearing, a knob 18 is fixedly installed on the top of the threaded rod 16, a connecting groove 17 is vertically provided in the middle of the upper surface of the fixing pin 15, the connecting groove 17 is spirally connected to the threaded rod 16, and the size of the fixing pin 15 matches that of the slide groove 14.

[0019] In this technical solution, the dam can be raised and protected by the heightened railing 11 fixedly connected between the columns 1. When someone falls into the water, the rescuer can rotate the threaded rod 16 through the knob 18. During the rotation of the threaded rod 16, the fixing pin 15 can be driven to move upward and retract into the slide groove 14, thereby releasing the lock on the rescue rod 13 and facilitating the removal of the rescue rod 13 from the limit groove 12.

[0020] In this embodiment, an outer side of one end of the rescue rod 13 is provided with an external thread 21 , and an inner thread 2 is provided at the other end of the rescue rod 13 . Two adjacent groups of rescue rods 13 are spirally connected via the external thread 21 and the inner thread 2 .

[0021] In this technical solution, the external threads 21 and the internal threads 2 at both ends of the rescue rod 13 facilitate the splicing and lengthening of multiple groups of rescue rods 13, and further enable the rescue of people who fall into the water.

[0022] In this embodiment, connecting sleeves 19 are fixedly installed at the upper and lower ends of both sides of the raised fence 11. The two ends of the raised fence 11 are movably connected to the connecting sleeves 19 on the outside of the column 1. The raised fence 11 and the column 1 are fixedly connected by bolts passing through the connecting sleeves 19.

[0023] In this technical solution, both ends of the heightened fence 11 are inserted into the connecting sleeves 19 on the outer sides of the corresponding columns 1, and then bolts are passed through the connecting sleeves 19 to fix the heightened fence 11 and the columns 1, which is convenient and quick.

[0024] When a dam heightening structure is used, the two ends of the heightening railing 11 are inserted into the connecting sleeves 19 on the outside of the corresponding column 1, and then the connecting sleeves 19 are penetrated by bolts to fix the heightening railing 11 to the column 1, so as to raise and protect the dam. When someone falls into the water, the rescuer can rotate the threaded rod 16 through the knob 18. During the rotation of the threaded rod 16, the fixing pin 15 can be driven to move upward and retract into the slide groove 14, thereby releasing the lock on the rescue rod 13, making it convenient to remove the rescue rod 13 from the limiting groove 12. Through the external threads 21 and the internal threads 2 at both ends of the rescue rod 13, it is convenient to splice and lengthen multiple groups of rescue rods 13, so as to further rescue the person who falls into the water. After the rescue is completed, the rescue rod 13 is disassembled and placed horizontally in the limiting groove 12, and then the knob 18 is rotated in the opposite direction to push the fixing pin 15 to fix the rescue rod 13 in the limiting groove 12.
