[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] Example 1, reference Figure 1 to Figure 2, which is the first embodiment of the present invention, provides a pit shielding device, including a load-bearing mechanism 100, including a central main pole 101 and a load-bearing frame 102, the central main pole 101 and the load-bearing frame 102 are connected by a fixed handle 103, and the load-bearing frame 102 is provided with an upper and lower layer; a connecting mechanism 200 is arranged on the load-bearing mechanism 100, which includes a fence post 201 and a ground spike 202 arranged at the bottom end of the fence post 201, and the fence post 201 is connected to the layer of the load-bearing frame 102 close to the ground spike 202.

[0027] Specifically, a load-bearing net 104 is provided on the load-bearing frame 102 .

[0028] The load-bearing net 104 is connected to the load-bearing frame 102 via fixing buckles.

[0029] Furthermore, the number of fence posts 201 is equal to the number of sides of the unfolded shape of the load-bearing frame 102, and the number of fence posts 201 is no less than 3 groups.

[0030] Example 2, reference Figure 1 to Figure 2 This embodiment is different from the first embodiment in that the end of the load-bearing frame 102 away from the ground bar 202 can be connected to the fence cross arm 105, and the load-bearing frame 102 and the fence cross arm 105 are movably connected.

[0031] Specifically, a snap-fitting groove 106 is provided at one end of the central main rod 101 close to the load-bearing frame 102 , and the connecting surface between the snap-fitting groove 106 and the central main rod 101 is arc-shaped.

[0032] Furthermore, the fixed handle 103 can slide up and down along the outer wall of the central main rod 101 , and an elastic block is provided on a side of the fixed handle 103 that is in contact with the central main rod 101 .

[0033] Furthermore, the elastic block is adapted to the engaging groove 106, and the surface where the elastic block and the engaging groove 106 are in contact is an arc surface.

[0034] The rest of the structure is the same as that of Example 1.

[0035] Example 3, reference Figure 1 to Figure 2 This embodiment is different from the above embodiments in that the fixed handle 103 slides up and down along the outer wall of the central main rod 101 to control the retracted and extended state of the load-bearing frame 102, and the retracted and extended state of the load-bearing net 104 is consistent with that of the load-bearing frame 102.

[0036] Specifically, the load-bearing structure 100 also includes a shielding cloth, which is movably connected to the ground stake 202. When the load-bearing frame 102 is in the unfolded state, the shielding cloth can simultaneously cover the central main rod 101 and the load-bearing frame 102 connected to the ground stake 202.

[0037] The rest of the structure is the same as that of Example 2.

[0038] Reference Figure 1 , the figure shows 6 groups of fence posts 201 and a load-bearing frame 102. When the load-bearing frame 102 is unfolded, the overall device is in an umbrella shape. Next, the umbrella-shaped pit shielding device in the schematic diagram will be used as an example for explanation. However, the present invention is not limited to the umbrella shape, and can be changed into other unfolding shapes according to the on-site construction environment. The principle is the same.

[0039] The specific working principle of the umbrella-shaped pit shielding device is to use an umbrella-shaped frame to complete the opening and closing of the device. What is different from the traditional umbrella structure is that the umbrella-shaped load-bearing frame 102 in the present invention is divided into two layers, the upper 6 frames and the lower 6 frames are evenly distributed. When the device is folded and opened, the upper and lower layers of the load-bearing frames 102 can move at the same time, and the upper and lower layers of the frames are supporting structures and load-bearing structures for each other. The traditional umbrella structure is a single-layer support frame, and the opening and closing actions are relatively weak in strength by adding oblique supports to the frame. The central main pole 101 in the umbrella structure is detachable. When it needs to be opened and folded, the central main pole 101 can be connected to the fixed handle 103 at the center connection of the load-bearing frame 102 by threading. When the device is folded, it can be folded into a long strip like an umbrella. When it is expanded, the device is located above the foundation pit, and the central main rod 101 is vertically upward, affecting the safety and stability. Therefore, the central main rod 101 can be unscrewed and brought back at this time, and then installed and used next time the device is retracted.

[0040] Secondly, this device is designed with a portable fence. The purpose of the fence is to form a warning area around the foundation pit and the device. It is portable and foldable, easy to carry. The top warning belt is surrounded in a ring to serve as a warning. The umbrella structure uses a skeleton as a supporting structure, and multiple layers of steel wire ropes are used between the skeletons to form a steel wire mesh structure. The upper part is covered with cloth to prevent small animals from falling. The quick-detachable fence can be quickly assembled and disassembled in a combination of six pieces, and a small red warning flag is wrapped around the upper part to serve as a protective warning.

[0041] Operation process: Move the fixed handle 103 along the outer wall of the central main pole 101 to the top of the central main pole 101 like opening an umbrella. At this time, the device is in the open state, and the fixed handle 103 is located in the locking groove 106; then cover the opened device on the pit at the construction site, and then insert the ground spikes 202 into the soil one by one. After fixing the ground spikes 202, fix the fence crossarms 105 and the ends of the fence posts 201 in turn. At this time, you can choose whether to separate the central main pole 101 from the load-bearing frame 102 according to the on-site construction environment, and then cover the entire device with an independent shielding cloth, tie and fix the cloth hexagon to the six ground spike 202 posts, and finally wrap the warning pennant around the fence crossarm 105 and hang it on the fence crossarm 105 to warn the site.

[0042] When the device needs to be stored, first separate the shielding cloth from the ground peg 202. If the central main pole 101 has been removed before, now connect the central main pole 101 with the fixing buckle, then pull the ground peg 202 out of the soil, and then slide the fixing buckle along the outer wall of the central main pole 101 to the other end. This process can be referred to the process of folding an umbrella. At this time, the entire device is in a folded state and can be stored for use next time.
