[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: A protective structure for outdoor fire hydrants, such as Figures 1-4 As shown, it includes a fire hydrant 17 and a screw barrel 1 evenly distributed on the outside of the fire hydrant 17. There are at least four screw barrels 1. The upper end of the screw barrel 1 is threadedly connected to a rotating bolt 2. The rotating bolt 2 is rotatably connected to a rotating column 4 at one end away from the screw barrel 1, and the rotating bolt 2 extends out of the upper end of the rotating column 4. The upper end of the rotating bolt 2 is fixedly connected to a rotating handle 3, and there is a certain gap between the rotating handle 3 and the rotating column 4. A rotating connecting column 9 is installed on the adjacent side of the two rotating columns 4, and a rotating connecting column 9 is installed on the adjacent side of the two screw barrels 1. The two rotating connecting columns 9 are rotatably connected to a telescopic rod 10. A telescopic receiving rod 11 is arranged between the two telescopic rods 10, and the opposite ends of the telescopic receiving rod 11 are simultaneously plugged into the telescopic rod 10.

[0026] Before installing the fire hydrant protection device, according to the specifications of the fire hydrant 17, the telescopic rods 10 are stretched outward respectively so that the telescopic rods 10 symmetrically distributed above and below move at the same time. Under the guidance and support of the telescopic receiving rod 11, the stability of the horizontal movement of the telescopic rods 10 is guaranteed, thereby improving the applicability of the device. After the telescopic rods 10 are moved to the appropriate position, the fire hydrant protection device is installed on the outside of the fire hydrant 17. At this time, when the ground is uneven, the rotating connection column 9 and the telescopic rod 10 are rotatably connected, so that the device can adapt to different heights and prevent one corner from being suspended in the air, thereby ensuring the stability of the device. After the horizontal adjustment is completed, according to the height of the fire hydrant 17, the rotating handle 3 is adjusted to drive the rotating bolt 2 to move in the height direction until the upper telescopic rod 10 moves beyond the height of the fire hydrant, which will not affect the use of the water outlet of the fire hydrant 17 and play a protective role for the fire hydrant 17. At the same time, the four rotating bolts 2 can be adjusted separately to facilitate the horizontal and height movement directly above the device, thereby increasing the flexibility of the device, improving the applicability of the device and ensuring the practicality of the device.

[0027] like Figures 1-4 As shown, the lower end of the screw barrel 1 is rotatably connected to a connecting column 5, and a positioning base 6 is installed at the end of the connecting column 5 away from the screw barrel 1.

[0028] A plurality of positioning holes 12 are formed through the upper surface of the positioning base 6 , and the positioning holes 12 are evenly distributed.

[0029] When the fire hydrant 17 is on a hard road, the positioning base 6 is closely fitted to the ground, and the expansion bolt passes through the positioning hole 12 to tightly connect the positioning base 6 to the ground, completing the installation and fixation of the device.

[0030] Example 2: A protective structure for outdoor fire hydrants, such as Figures 1-4 As shown, a ground nail 7 is inserted into the lower end of the connecting column 5, and the positioning base 6 is inserted into the ground nail 7.

[0031] A plurality of barbs 8 are installed on the outer surface of the ground nail 7, and the barbs 8 are evenly distributed at corresponding positions.

[0032] When the fire hydrant 17 is on a rough road surface, the ground nails 7 are installed and inserted into the ground. With the cooperation of the barbs 8 on both sides, the device can be effectively prevented from loosening and the stability of the device can be ensured. At the same time, multiple ordinary ground nails can be inserted through the positioning holes 12 to reinforce the device again.

[0033] A screw hole 13 is provided at the lower end of the connecting column 5 , and an external thread 14 is provided on the side of the ground nail 7 close to the connecting column 5 . The ground nail 7 is screwed together with the screw hole 13 through the external thread 14 .

[0034] The ground nail 7 can be installed in advance. Based on the rotational connection between the connecting column 5 and the screw barrel 1, the connecting column 5 is rotated, and the connecting column 5 is tightly connected to the ground nail 7 under the threaded connection between the external thread 14 and the screw hole 13, which facilitates installation and improves the flexibility of the device.

[0035] like Figures 1-4 As shown, a rotation groove 15 is passed through the rotation connecting column 9 near the telescopic rod 10 , and a rotation support column 16 is installed on the inner wall of the rotation groove 15 , and the rotation support column 16 is rotatably connected to the telescopic rod 10 .

[0036] Under the support of the rotating support column 16, the stability of the rotation angle of the telescopic rod 10 is guaranteed. At the same time, the movable groove 15 ensures the inclusiveness of the rotation angle of the telescopic rod 10, ensures the range of movement of the telescopic rod 10, improves the ability of the device to adapt to roads of different heights, and ensures the scope of application of the device.

[0037] Working principle: Before installing the fire hydrant protection device, according to the specifications of the fire hydrant 17, the telescopic rods 10 are stretched outward respectively, so that the telescopic rods 10 symmetrically distributed above and below move at the same time. When the telescopic rods 10 are moved to the appropriate position, the fire hydrant protection device is installed to the outside of the fire hydrant 17. After the horizontal adjustment is completed, according to the height of the fire hydrant 17, the rotating handle 3 is adjusted to drive the rotating bolt 2 to move in the height direction until the upper telescopic rod 10 moves beyond the height of the fire hydrant, which will not affect the use of the water outlet of the fire hydrant 17. At this time, when the fire hydrant 17 is on a hard road, the positioning base 6 is tightly fitted with the ground, and the expansion bolt passes through the positioning hole 12 to tightly connect the positioning base 6 to the ground, completing the installation and fixation of the device. When the fire hydrant 17 is not on a hard road, install the ground nail 7 and insert the ground nail 7 into the ground. With the cooperation of the barbs 8 on both sides, the installation and fixation are completed.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
