For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.

[0033] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0034] As shown in Figure 1 A site investigation shielding device, comprising a plurality of support columns 1 and a shielding device 2 connected between adjacent two support columns 1, specifically, can be as Figure 1 Four support columns and four shielding devices are adopted to enclose a square region.

[0035] As shown in Figure 2The support column 1 comprises a first cylinder 11, a sliding block 12, a support leg 13 and a support assembly. The top of the first cylinder 11 is sealed and the bottom is open. The size of the opening is smaller than the inner diameter of the first cylinder. The sliding block 12 is arranged in the first cylinder 11 and can slide up and down. The lower part of the side wall of the first cylinder 11 is provided with a fixed hole 112 near the bottom. The side wall of the sliding block 12 is provided with a ball head plunger 121 which is used in cooperation with the fixed hole 112. When the sliding block slides to the lower part of the first cylinder near the bottom, the ball head plunger is clamped in the fixed hole, thereby fixing the sliding block. When it is needed to move the sliding block, the ball head plunger can be pressed back. The lower surface of the sliding block 12 is hinged with 3-4 support legs 13. The support legs 13 can pass through the bottom of the first cylinder 11 and can support the first cylinder. The sliding block 12 is further provided with a support assembly for supporting the support legs 13, preventing the support legs from being unstable. The outer side wall of the first cylinder 11 is provided with a clamping block 111.

[0036] As shown in the drawings, Figures 7-9 The cover 2 comprises two second cylinders 21 which are connected in parallel and integrally. The second cylinder 21 is provided with a rotating shaft inside. One end of the cover cloth 26 is wound on the rotating shaft. The side wall of the second cylinder 21 is provided with a slit 211 through which the other end of the cover cloth 26 passes. The other end of the cover cloth 26 is provided with a buckle 27 which is used in cooperation with the clamping block 111. When in use, the cover cloth is pulled and the buckle is buckled on the clamping block. The second cylinder 21 is fixed on the base 22. The upper surface of the base 22 is provided with a receiving groove. The rotating shaft extends downward into the receiving groove and is connected with the clockwork 23 in the receiving groove. The connection mode of the clockwork and the rotating shaft is the conventional mode. The clockwork provides power for the rotation of the rotating shaft. The lower surface of the base 22 is screwed with an adjusting bolt 24. The bottom end of the adjusting bolt 24 is provided with a supporting pad 25. The supporting pad is in contact with the ground by adjusting the adjusting bolt, thereby supporting the cover.

[0037] The device comprises a plurality of support columns and covers connected between adjacent two support columns. The first cylinder side wall of the support column is provided with a clamping block. The cover cloth of the cover is provided with a buckle. The connection of the corresponding clamping block and buckle can connect the support column and the cover, and also facilitates disassembly. The bottom support leg of the support column is hinged on the sliding block inside. When not in use, it can be stored in the support column, saving storage space. When in use, it can be pulled out and made into a support leg through the support assembly. The cover cloth of the cover is wound on the rotating shaft. The bottom end of the rotating shaft is connected with the clockwork. The clockwork can provide power for the rotation of the rotating shaft. When the cover cloth is pulled out, the clockwork is stressed. When the cover cloth is released, the clockwork is no longer stressed, driving the rotating shaft to rotate, thereby storing the cover cloth in the second cylinder, facilitating storage and use.

[0038] For example, Figure 3As shown, the support assembly comprises a guide rod 14, a support rod 15, a sliding ring 16 and a locking bolt 17; the guide rod 14 is vertically fixed on the lower surface of the sliding block 12, and the sliding ring 16 is slidably arranged on the guide rod 14; one end of the support rod 15 is hingedly connected with the sliding ring 16, and the other end is hingedly connected with the support leg 13; the side wall of the sliding ring 16 is screwed with the locking bolt 17. When the sliding block is slid downward, the support leg can be unfolded, and when the sliding block is pushed upward, the support leg can be folded, as shown in Figure 6 As shown, after the support leg is folded, it can be pushed into the first cylinder for storage.

[0039] Specifically, the bottom end of the guide rod 14 is also provided with a circular support bracket 18, and the diameter of the support bracket 18 is greater than that of the guide rod 14. The support bracket plays a supporting role on the ground and can prevent the sliding ring from falling out.

[0040] For example, as shown in Figures 4-5 , the inner side wall of the first cylinder 11 is provided with a protrusion 113 extending along the length direction thereof, and the side wall of the sliding block 12 is provided with a groove 122 matched with the protrusion 113. The protrusion and the groove play a limiting role to prevent the sliding ring from rotating when it slides up and down.

[0041] Specifically, the protrusion 113 is 2 and symmetrically arranged.

[0042] For example, the bottom of the first cylinder 11 is also provided with a detachable cover 19, which can be inserted or screwed. The cover plays a sealing role for the first cylinder and prevents the support leg from extending out of the first cylinder when not in use.

[0043] When the support column is released, the first cylinder can be vertically placed with the opening downward, the cover is opened, and under the action of gravity, the support leg automatically slides out of the first cylinder, and then the sliding block is fixed by the ball plunger. When it is retracted, the ball plunger is pressed, the support leg is pushed in, the sliding block is no longer clamped, and then the support leg is pushed into the first cylinder and the cover is closed.

[0044] For example, as shown in Figure 5 , the sliding block 12 comprises an upper cylinder and a lower cylinder which are integrally connected from top to bottom, and the support leg 13 is hingedly connected to the lower surface of the lower cylinder; the diameter of the upper cylinder is greater than that of the lower cylinder, and the diameter of the upper cylinder is equal to the inner diameter of the first cylinder 11; the diameter of the lower cylinder is equal to the diameter of the opening at the bottom of the first cylinder 11, and the thickness of the lower cylinder is equal to the wall thickness of the first cylinder 11; when the sliding block 12 slides to the bottom of the first cylinder 11, the lower surface of the lower cylinder is flush with the outer surface of the bottom of the first cylinder 11. This arrangement can ensure that the support leg can be fully extended out of the first cylinder.

[0045] Exemplarily, the outer side wall of the first barrel body 11 is provided with 4 columns and 3 rows of clamping blocks 111 which are uniformly distributed, and the shielding cloth 26 is correspondingly provided with 3 buckles 27 which are distributed vertically.

[0046] Exemplarily, the slits 211 on the two second barrel bodies 21 are located in the same plane.

[0047] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
