[0028] Example:

[0029] See also Figures 1 to 5A portable fence for water conservancy projects includes a fence assembly 1, the fence assembly 1 includes a first support rod 101 and a second support rod 102, the first support rod 101 is hinged at one end close to the second support rod 102 with a pair of symmetrical Second adjustment lever 104, a pair of first adjusting rods 103 symmetrically arranged in upper and lower directions are hingedly connected to the end of the second support rod 102 close to the first support rod 101, and the pair of first adjusting rods 103 are arranged in a one-to-one correspondence with the pair of second adjusting rods 104. The second adjusting rod 104 is fixedly connected with a hinge sleeve 106 at one end away from the first support rod 101, and the first adjusting rod 103 is fixedly connected with a hinge shaft 105 at one end away from the second support rod 102, and the hinge shaft 105 and the hinge sleeve 106 are hinged to each other, and a plurality of sliding connection blocks 107 are fixedly connected to the middle part of the second support rod 102, and the overall shape of the sliding connection block 107 is T-shaped.

[0030] This solution can complete the mutual splicing of two or more fence assemblies 1 by inserting multiple sliding connection blocks 107 in the middle of the second support rod 102 into the interior of the first support rod 101, thereby expanding the protection range and achieving convenience through folding and splicing. At the same time, both sides of the first support rod 101, the second support rod 102, the first adjustment rod 103 and the second adjustment rod 104 are all set with rounded arcs, which can effectively reduce wind resistance and prevent the problem that the water conservancy project construction site is relatively open and the water conservancy project is blown down by strong wind. At the same time, with the mutual hinged setting between the first support rod 101, the second support rod 102, the first adjustment rod 103 and the second adjustment rod 104, it can play a role of adaptive adjustment when facing uneven ground, and is suitable for water conservancy project construction sites.

[0031] See also Figure 4 A T-shaped groove is provided in the middle of the first support rod 101 to cooperate with the sliding connection block 107. This solution can quickly splice and fix the first support rod 101 and the second support rod 102 to each other through the setting of the sliding connection between the T-shaped groove and the sliding connection block 107.

[0032] See also Figure 4 The first support rod 101 and the second support rod 102 are both provided with strip grooves at the ends close to each other. Through the provision of the strip grooves, the first adjustment rod 103 and the second adjustment rod 104 can be stored after being folded, so that the entire volume becomes smaller and the portability is further improved.

[0033] See also Figure 5A rectangular groove is provided in the middle of the second adjusting rod 104 to cooperate with the installation of the hinge sleeve 106, and a strip groove is provided in the middle of the first adjusting rod 103 to cooperate with the installation of the hinge shaft 105. In this scheme, the hinge sleeve 106 and the hinge shaft 105 are respectively installed in the second adjusting rod 104 and the first adjusting rod 103 through the grooves, which can reduce the gap between the second adjusting rod 104 and the first adjusting rod 103 when the second adjusting rod 104 and the first adjusting rod 103 are folded, further reduce the volume after folding, and improve portability.

[0034] See also Figures 1 to 5 The lower ends of the first support rod 101 and the second support rod 102 are both provided with a placement base. In this solution, the first support rod 101 and the second support rod 102 can be placed upright on the ground through the placement base.

[0035] Working principle: If it is necessary to protect the construction site of a water conservancy project to prevent non-staff from approaching and causing danger, it is necessary to first transport multiple fence assemblies 1 to the construction site that needs protection, and then directly manually pull the first support rod 101 and the second support rod 102 apart to separate them. When the first support rod 101 and the second support rod 102 are pulled, a pair of first adjustment rods 103 and second adjustment rods 104 hinged between the first support rod 101 and the second support rod 102 are driven to fully open. After opening, it can be placed in the area that needs protection, and the multiple sliding connection blocks 107 in the middle of the second support rod 102 can be inserted into the first support rod 10 1, two or more fence components 1 can be spliced ​​together to expand the protection range, and convenience is achieved by folding and splicing. At the same time, both sides of the first support rod 101, the second support rod 102, the first adjustment rod 103 and the second adjustment rod 104 are arranged in a rounded arc shape, which can effectively reduce wind resistance and prevent the water conservancy project construction site from being blown down by strong wind in a relatively open area. At the same time, with the mutual hinged arrangement between the first support rod 101, the second support rod 102, the first adjustment rod 103 and the second adjustment rod 104, it can play a role of adaptive adjustment when facing uneven ground, and is suitable for water conservancy project construction sites.

[0036] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
