[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0022] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The embodiment of the utility model provides a foundation pit protection device, comprising a plurality of fence units connected in sequence along a first direction, wherein the fence unit comprises a frame 1 and a connection assembly 2. The connection assembly 2 is arranged on both sides of the frame 1 along the first direction, and the connection assembly 2 comprises a cantilever 7, which is rotatably connected to the frame 1, and the rotation axis of the cantilever 7 is perpendicular to the first direction. Along the first direction, two clamping arms 8 are arranged on one side of the cantilever 7, and the two clamping arms 8 are arranged oppositely along the rotation axis of the cantilever 7, and the clamping arm 8 is movably provided with a plug-in portion 9 along the rotation axis of the cantilever 7, and an elastic member 10 is arranged between the plug-in portion 9 and the clamping arm 8, and a plurality of plug-in holes 11 are arranged on the other side of the cantilever 7, and the axes of the plurality of plug-in holes 11 extend along the rotation axis of the cantilever 7, and the plurality of plug-in holes 11 are arranged circumferentially around the rotation axis of the cantilever 7.

[0024] The frame 1 forms a shielding structure of the fence unit.

[0025] The first direction may be parallel to the horizontal direction.

[0026] The cantilever 7 is rotatably connected to the frame 1 so that the opposite sides of the two cantilevers 7 can be adjusted between two adjacent fence units. For example, between two adjacent fence units, the side of one cantilever 7 where the clamping arm 8 is set can be opposite to the side of the other cantilever 7 where the plug-in hole 11 is set.

[0027] When connecting two adjacent fence units, the two plug-in parts 9 of the clamping arm 8 of one of the cantilevers 7 are separated, and the side of the other cantilever 7 provided with the plug-in hole 11 is set between the two plug-in parts 9, so that the two plug-in parts 9 can be inserted into the plug-in hole 11.

[0028] There are multiple plug-in holes 11. On the one hand, one of the multiple plug-in holes 11 can be selected to cooperate with the plug-in part 9. On the other hand, the multiple plug-in holes 11 allow the cantilever 7 to be docked with multiple other cantilevers 7, so that one fence unit can be connected to multiple fence units, increasing the flexibility of the layout of the fence units.

[0029] The two plug-in parts 9 are respectively inserted into the plug-in hole 11 from both ends of the plug-in hole 11, thereby increasing the connection reliability between two adjacent fence units.

[0030] Two adjacent fence units are connected by the plug-in portion 9 and the plug-in hole 11, which makes the connection more convenient and more reliable compared to the traditional connection method.

[0031] The elastic member 10 may be a spring, and is used to provide an elastic force to bring the two plug-in parts 9 closer to each other.

[0032] In some embodiments, the clamping arm 8 is provided with a sliding hole, and the plug-in portion 9 is inserted into the sliding hole.

[0033] The plug-in portion 9 is inserted into the sliding hole so that the plug-in portion 9 is slidably connected to the clamping arm 8 .

[0034] See also Figure 2 In some embodiments, limiting bosses are respectively provided on opposite sides of the two plug-in portions 9 .

[0035] The opposite side of the plug-in portion 9 refers to the side where the plug-in portions 9 on both sides are away from each other.

[0036] On the one hand, the limiting boss is used to limit the moving distance of the plug-in part 9 along the sliding hole, reducing the risk of the plug-in part 9 detaching from the sliding hole. On the other hand, in the embodiment where the elastic member 10 is a spring, the limiting boss can be used to connect the spring and the plug-in part 9.

[0037] See also Figure 2 In some embodiments, pins 6 are provided on both sides of the cantilever 7 along the first direction, and the pins 6 are movably connected to the cantilever 7 along the rotation axis of the cantilever 7. The frame 1 is provided with pin holes, and two pins 6 are selectively inserted into the pin holes.

[0038] The pin 6 cooperates with the pin hole to lock the cantilever 7 so that the opposite sides of two adjacent fence units can be fixed.

[0039] The two pins 6 may correspond to the two sides of the cantilever 7 where the plug-in portion 9 and the plug-in hole 11 are respectively provided.

[0040] See also Figure 1 In some embodiments, the fence unit further includes a mesh frame 3 , the frame body 1 is hollow inside, and the mesh frame 3 is accommodated in the frame body 1 .

[0041] The mesh frame 3 is used to enclose the frame body 1, so that the fence unit has a barrier effect while reducing the weight of the fence unit.

[0042] The mesh frame 3 is accommodated in the frame body 1 , that is, the frame body 1 is disposed around the mesh frame 3 in the circumferential direction.

[0043] The mesh frame 3 is accommodated in the frame body 1 , so that the mesh frame 3 can be removed from the frame body 1 , which is convenient for replacing the mesh frame 3 .

[0044] See also Figure 1 In some embodiments, the mesh frame 3 is provided with a plurality of expansion parts 4 around the circumference of the mesh frame 3, and the expansion parts 4 are connected to the frame body 1 by bolts.

[0045] The mesh frame 3 is connected to the frame 1 by connecting the plurality of expansion parts 4 to the frame 1 , thereby increasing the connection reliability between the mesh frame 3 and the frame 1 .

[0046] The expansion portion 4 and the frame body 1 are connected by bolts, so that the mesh frame 3 can be detachably connected to the frame body 1 .

[0047] See also Figure 1 In some embodiments, a support base 5 is disposed at the bottom of the frame 1 , and along the second direction, one side of the support base 5 is large and the other side is small, and the frame 1 is connected to the small side of the support base 5 .

[0048] The second direction may be a vertical direction.

[0049] One side of the support base 5 is larger than the other side. The larger side of the support base 5 can be the side placed on the ground. The frame 1 is connected to the smaller side of the support base 5, which increases the stability of the frame 1 standing on the ground.

[0050] In this embodiment, the support seat 5 can be a frustum-shaped structure.

[0051] In some embodiments, the support base 5 is hollow inside, and the support base 5 is provided with a medium input channel and a medium output channel.

[0052] The support seat 5 is hollow inside, so that when in use, fillers can be added into the support seat 5 to increase the weight of the support seat 5. When transporting the fence unit, the fillers in the support seat 5 can be released to reduce the weight of the support seat 5.

[0053] The medium input channel is used to input fillers into the support seat 5 , and the medium output channel is used to discharge the fillers in the support seat 5 .

[0054] The filler may be water, and the medium input channel and the medium output channel may be respectively provided with switches to switch the corresponding channels.

[0055] The above embodiments are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
