[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] As Figures 1-4 shown, a fence for municipal civil engineering includes a plurality of bases 1. The plurality of bases 1 are used in a spliced manner. At both ends inside the base 1, there are rotatably connected rotating blocks 15. On the rotating blocks 15, there are rotatably connected reels 5. On one of the reels 5 inside the base 1, there is wound an enclosure cloth 2, and the other reel 5 is connected to one side of the enclosure cloth 2 by bolts. The top end of the reel 5 is rotatably connected to a rotating frame 3 fixed on the rotating block 15. On both sides of the outer wall of one side of the base 1 inside the enclosure cloth 2, there are fixedly connected tracks 9. On the tracks 9, there are inserted slide blocks 10. The top edge of the slide block 10 is fixedly connected to a connecting column 11. On one side of the connecting column 11, there is rotatably connected a diagonal tension arm 7. The swinging end of the diagonal tension arm 7 is hinged to a support arm 6. One end of the support arm 6 is connected to the rotating frame 3 by a pin and the other end is used for fixing on the ground:

[0024] In actual use, by means of the rotational connection of the rotating block 15, the rotating frame 3 drives the reel 5 to rotate out of the base 1 until it is perpendicular to the base 1. Then, the position of the rotating block 15 is fixed, and the enclosure cloth 2 on one of the reels 5 is pulled. One side of the enclosure cloth 2 is fixed to the other reel 5 by bolts. In addition, by fixing the relative position of the fixed slider 10 and the track 9, and then using the swing of the diagonal pull arm 7 to adjust the position of the support arm 6, the top end of the support arm 6 is fixed to the rotating frame 3 by a pin, and the other end is fixed to the ground by an expansion bolt or other means. The support arm 6 is used to support the positions of the base 1 and the reel 5 to prevent the enclosure cloth 2 and the reel 5 from tipping over. And due to the rotational connection between the rotating block 15 and the base 1, the reel 5 can be stored in the base 1, and by rotating and winding the enclosure cloth 2 around the reel 5, the storage of the enclosure cloth 2 and the reel 5 can be realized.

[0025] Further: A bidirectional screw rod 14 is rotatably connected to the inner bottom surface of the base 1 by embedding. Both ends of the bidirectional screw rod 14 extend to the two rotating blocks 15 respectively and are threadedly connected with sliding seats 17 inserted into the inner bottom surface of the base 1. A pull rod 16 is rotatably connected to the sliding seat 17. The swinging end of the pull rod 16 is hinged with a plug-in member 18 inserted into the opposite side walls of the base 1 and inserted into the bottom ends of the rotating block 15 and the reel 5.

[0026] In this solution, the periphery of the bottom edge of the reel 5 is provided with a hollow. When the rotating block 15 rotates until the reel 5 is perpendicular to the inner bottom surface of the base 1, the bidirectional screw rod 14 rotates, causing the sliding seats 17 at both ends of its surface to move away from each other. Under the pushing action of the pull rod 16, the plug-in member 18 rises along the side wall of the base 1 until it passes through the rotating block 15 and the reel 5. The plug-in connection between the plug-in member 18 and the side wall of the base 1 prevents the plug-in member 18 from rotating. Furthermore, due to the non-rotation of the plug-in member 18, the rotating block 15 and the reel 5 penetrated by the plug-in member 18 do not rotate.

[0027] Two meshing bevel gears 13 are embedded in the inner bottom surface of the base 1. One of the bevel gears 13 is fixed in the middle of the rod surface of the bidirectional screw rod 14, and the other bevel gear 13 is rotatably installed in the base 1 and one end extends out of the base 1 through the base 1. By rotating the extended end of the bevel gear 13, the bevel gear 13 rotates, and under the action of meshing connection, the other bevel gear 13 drives the bidirectional screw rod 14 connected to it to rotate.

[0028] In addition: A pin shaft 12 threadedly connected to the side of the rotating frame 3 penetrates through the top edge of the connecting column 11. The slider 10 at the bottom edge of the connecting column 11 is bolted to the side of the base 1. A connecting arm 8 is hinged between the other end of the support arm 6 and the side surface of the slider 10: By using the pin shaft 12 to penetrate the connecting column 11 and the vertical rotating frame 3, and using the insertion of the slider 10 and the track 9 to ensure that the slider 10 and the connecting column 11 on its surface remain in a vertical state. Therefore, under the action of the pin shaft 12, the rotating frame 3 can be kept in a vertical state, and the bolts in this solution can fix the relative position of the slider 10 and the track 9, such asFigure 4 As shown, the connecting arm 8 is composed of two hinged parts, and the endpoints of the two parts are respectively hinged to the bottom end of the support arm 6 and the side of the slider 10. Therefore, in actual use, the position of the support arm 6 is fixed by passing expansion bolts through the connecting arm 8 and inserting them into the ground, thereby realizing the relative position fixation between the support arm 6 and the slider 10.

[0029] In addition: An extension plate 4 is installed between two adjacent bases 1. The extension plate 4 is installed inside the enclosure cloth 2 and the top edge of the extension plate 4 is inserted into the rotating frame 3. The bottom edge of the extension plate 4 is U-shaped and the bottom edge of the extension plate 4 is inserted into two adjacent bases 1. By inserting the extension plate 4 provided between two adjacent rotating frames 3, the gap between two adjacent enclosure cloths 2 is covered.

[0030] Working principle: Arrange a number of bases 1 along the periphery of the construction area, rotate the rotating frame 3 to be perpendicular to the base 1, pull out the enclosure cloth 2 on one of the reels 5, fix one side of the enclosure cloth 2 to the other reel 5 with bolts, then rotate the bidirectional screw 14 to make the sliding seats 17 at both ends of its surface move away from each other. Under the pushing action of the pull rod 16, the plug-in 18 rises along the side wall of the base 1 until it passes through the rotating block 15 and the reel 5. Fix the slider 10 to the position corresponding to the rotating frame 3 on the track 9 with bolts, swing the diagonal tension arm 7 to adjust the position of the support arm 6, fix the top end of the support arm 6 to the rotating frame 3 with a pin, and fix the other end to the ground by expansion bolts or other means. Use the support arm 6 to support the positions of the base 1 and the reel 5, and finally install the extension plate 4 between two adjacent bases 1.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
