Description

Technical Field

[0001] This utility model relates to the field of construction protective fence technology, specifically a protective fence for municipal water conservancy engineering construction. Background Technology

[0002] Protective fences for water conservancy construction are protective facilities used in the construction of water conservancy projects. They are mainly used to protect the safety of personnel and equipment at the construction site and prevent accidents.

[0003] For example, the Chinese authorized patent with publication number CN221609686U (A Protective Barrier for Water Conservancy Engineering Construction) includes triangular brackets, positioning cones, and connectors. There are two triangular brackets, with the positioning cones connected to the lower sides of both the left and right sides of each bracket, and the connectors connected to the front and rear sides of both the upper and lower parts of each bracket. This utility model uses a crash barrier to block impacting objects, and in conjunction with a compression spring, reduces the impact force, thus protecting both the impacting object and the protective barrier and preventing serious accidents caused by the impact.

[0004] However, most existing protective fences used in municipal water conservancy construction rely on bolt connections for the installation of posts and netting. Disassembly and installation require tools, which is time-consuming and labor-intensive, leading to inconvenience. Therefore, they do not meet the current needs. To address this, we have proposed a new type of protective fence for municipal water conservancy construction. Utility Model Content

[0005] The purpose of this utility model is to provide a protective fence for municipal water conservancy engineering construction, so as to solve the problem mentioned in the background art that the existing protective fences for municipal water conservancy engineering construction are mostly connected by bolts when installing the posts and protective nets, and disassembly and installation require tools, which is time-consuming and labor-intensive, resulting in inconvenience in installation and disassembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective fence for municipal water conservancy engineering construction, comprising: a post, a limiting component at the top of the post, a first guardrail on one side of the post, and a second guardrail on the other side of the post, the first and second guardrails being connected to the post by connecting components, both the first and second guardrails including a protective frame and a metal mesh, the metal mesh being welded and fixed to the inner wall of the protective frame, and limiting grooves being provided on the front and rear surfaces at both ends of the protective frame, the bottom of the limiting grooves being open.

[0007] Preferably, the limiting component includes a rotating seat and a limiting seat, and two limiting seats are provided, with the two limiting seats respectively welded to the two side surfaces of the rotating seat.

[0008] Preferably, the lower surface of the rotating seat is welded with a threaded post, and the center of the upper surface of the column is provided with a threaded groove, and the threaded post and the threaded groove are threadedly connected.

[0009] Preferably, the front and rear surfaces of the rotating base are provided with finger grooves, and multiple finger grooves are provided.

[0010] Preferably, the lower surface of the limiting seat is provided with an embedded groove, and the bottom end of the embedded groove is open, and a rubber pad is embedded inside the embedded groove.

[0011] Preferably, the connecting component includes a connecting seat, which is welded and fixed to the outer wall of the column. The upper surface of the connecting seat is provided with a mounting slot, which extends through the connecting seat vertically. One side of the mounting slot is open, and the protective frame is inserted along the mounting slot.

[0012] Preferably, the connecting component further includes a limiting slider, which is welded to the inner walls on both sides of the mounting slot and moves along the limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model provides connecting components on both sides of the column, a limiting component at the top of the column, and limiting grooves on the front and rear surfaces of both sides of the protective frame. The protective frame is inserted from top to bottom along the mounting slot of the connecting seat, which limits the first guardrail and the second guardrail and prevents them from tipping over. The limiting slider moves along the limiting groove. After the first guardrail and the second guardrail have moved to the bottom, the top of the limiting slider contacts the top of the limiting groove, which prevents them from sliding down and falling. This connects the first guardrail and the second guardrail to the column. Then, the rotating seat is rotated, and the limiting seat squeezes the protective frame to prevent the protective frame from moving upward and separating from the column or shifting its position. When it is necessary to disassemble the first guardrail and the second guardrail, it is only necessary to rotate the rotating seat, and the limiting seat separates from the protective frame. Then, the first guardrail and the second guardrail can be moved upward and removed. This is simple and convenient, improves the convenience of installation and disassembly, and solves the problem that most of the existing protective fences used in municipal water conservancy construction are connected by bolts when the columns and protective nets are installed. Disassembly and installation require tools, which is time-consuming and laborious, resulting in inconvenience in installation and disassembly.

[0015] (2) By setting an embedded groove on the lower surface of the limit seat and setting a rubber pad inside the embedded groove, when the limit seat squeezes the protective frame, the rubber pad contacts the protective frame, avoiding surface damage caused by hard friction between the protective frame and the limit seat, thus improving protection and service life.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a protective fence for municipal water conservancy engineering construction, comprising: a post 1, a limit component 4 at the top of the post 1, a first guardrail 2 on one side of the post 1, and a second guardrail 3 on the other side of the post 1. Both the first guardrail 2 and the second guardrail 3 are connected to the post 1 via connecting components 5. Both the first guardrail 2 and the second guardrail 3 include a protective frame 7 and a metal mesh 8, with the metal mesh 8 welded and fixed to the inner wall of the protective frame 7. Limit sliding surfaces are provided on the front and rear surfaces at both ends of the protective frame 7. The groove 6 is open at the bottom. The connecting component 5 includes a connecting seat 14, which is welded to the outer wall of the column 1. The upper surface of the connecting seat 14 is provided with an installation slot 15, which extends through the connecting seat 14 vertically. One side of the installation slot 15 is open. The protective frame 7 is inserted along the installation slot 15. The connecting component 5 also includes a limiting slider 16, which is welded to the inner walls on both sides of the installation slot 15. The limiting slider 16 moves along the limiting groove 6.

[0023] The first guardrail 2 and the second guardrail 3 are fixed to both sides of the column 1 respectively. When fixing, the protective frames 7 of the first guardrail 2 and the second guardrail 3 are inserted from top to bottom along the mounting slots 15 of the connecting seats 14 on both sides of the column 1, so as to limit the first guardrail 2 and the second guardrail 3 and prevent them from tipping over.

[0024] Furthermore, during insertion, the limiting slider 16 moves along the limiting groove 6. The bottom of the limiting groove 6 is open, and the top is closed. After the first guardrail 2 and the second guardrail 3 have moved to the bottom, the top of the limiting slider 16 contacts the top of the limiting groove 6. Figure 1 As shown, it serves to prevent slippage and falling, and connects the first guardrail 2 and the second guardrail 3 to the post 1;

[0025] The limiting component 4 includes a rotating seat 10 and a limiting seat 11, and there are two limiting seats 11. The two limiting seats 11 are welded to the two side surfaces of the rotating seat 10 respectively. A threaded post 12 is welded to the lower surface of the rotating seat 10. A threaded groove 9 is provided at the center of the upper surface of the post 1, and the threaded post 12 is threadedly connected to the threaded groove 9. Finger grooves 13 are provided on both the front and rear surfaces of the rotating seat 10, and there are multiple finger grooves 13. An embedded groove 17 is provided on the lower surface of the limiting seat 11, and the bottom end of the embedded groove 17 is open. A rubber pad 18 is embedded inside the embedded groove 17.

[0026] Personnel insert their fingers into the finger groove 13 to easily grasp the rotating seat 10. Rotating the rotating seat 10 causes the threaded post 12 to connect with the threaded groove 9, allowing the rotating seat 10 to continue moving downwards until it can no longer rotate. At this point, the lower surface of the rubber pad 18 contacts the upper surface of the protective frame 7. Figure 1 As shown, the protective frame 7 is squeezed by the limiting seat 11 to prevent the protective frame 7 from moving upward and separating from the column 1 and from positional displacement, thereby improving the stability of the connection.

[0027] When it is necessary to disassemble the first guardrail 2 and the second guardrail 3, simply rotate the rotating seat 10 to separate the limiting seat 11 from the protective frame 7, and then move it upward to remove the first guardrail 2 and the second guardrail 3. This is simple and convenient, and improves the ease of installation and disassembly.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
