Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically to safety protection fences for engineering construction. Background Technology

[0002] Construction projects refer to all types of buildings and engineering facilities that provide the material and technical foundation for human life and production. To prevent unauthorized personnel from entering the construction site, protective fences need to be erected around the perimeter of the construction site.

[0003] Because construction typically generates significant dust, spray pipes are installed on top of protective fences to spray water and suppress dust, preventing it from spreading. However, when the fences are close to roads, the sprayed water mist can easily splash pedestrians, causing inconvenience and even obstructing normal passage. Therefore, a safety protective fence for engineering construction is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safety fence for engineering construction, which can disperse water mist at a higher level, preventing a large amount of water mist from spreading to the sides and below the fence frame and wetting pedestrians, thus not affecting the normal passage of pedestrians.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection fence for engineering construction, including a fence frame and support legs installed at its bottom. Several sets of elastic clips for clamping dust suppression pipes are installed at intervals on the top side of the fence frame, and a ventilation pipe is installed horizontally through the top of the fence frame. Several sets of air spray pipes extending out of the top of the fence frame are installed vertically at the top of the ventilation pipe. One end of the ventilation pipe extends out of the side of the fence frame, and the other end is connected to a flexible hose, which is adapted to the extended end of the ventilation pipe. An interlocking mechanism is provided on the side of the fence frame, and adjacent fence frames are stably connected through the interlocking mechanism. A clamping mechanism for locking the flexible hose is installed at the side end of the fence frame corresponding to the extension end of the ventilation pipe.

[0006] Preferably, the end of the elastic clip facing away from the fence frame is provided with an opening to allow the dust suppression pipe to enter.

[0007] Preferably, the interlocking mechanism includes a first connecting hole block fixed to one end of the fence frame, a second connecting hole block fixed at the other end of the fence frame at a offset position, and bolts installed between the first connecting hole blocks on one set of fence frames and the second connecting hole blocks on another set of fence frames.

[0008] Preferably, the clamping mechanism includes support seats symmetrically fixed on both sides of the extension end of the ventilation pipe, a movable rod is slidably installed through the support seats, an arc-shaped pressure plate is fixed at the inner end of the movable rod, a limit plate is fixed at the outer end of the movable rod, and a tension spring is sleeved on the movable rod at the position between the limit plate and the support seat.

[0009] Preferably, the clamping mechanism includes support plates symmetrically fixed on both sides of the extension end of the ventilation pipe, with a screw threadedly installed on the support plate, and a clamping plate rotatably installed on the inner end of the screw.

[0010] Preferably, a baffle is fixed to the top of the fence frame, and the top of the baffle is curved.

[0011] This utility model provides a safety protection fence for engineering construction, which has the following advantages compared with the prior art: 1. By installing ventilation pipes, air spray pipes, and flexible hoses, and by using flexible hoses to connect the extension ends of ventilation pipes on adjacent fence frames, air can be blown into them. Multiple sets of air spray pipes blow air upwards, which can blow the water mist sprayed from the dust suppression pipes further upwards, so that the water mist can be dispersed at a higher level, avoiding a large amount of water mist from being dispersed on the sides and below the fence frame and wetting pedestrians, and will not affect the normal passage of pedestrians.

[0012] 2. By setting up baffles, the airflow from the spray pipe is directed towards the interior of the construction site, which can blow the water mist into the construction site and effectively prevent the water mist from drifting onto the road and affecting pedestrian traffic.

[0013] 3. By setting up a clamping mechanism, the phenomenon of the hose falling off from the extension end of the adjacent ventilation pipe is effectively prevented, thus improving the stability of the connection between the hose and the pipe. Attached Figure Description

Detailed Implementation

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] Example 1 In some construction projects, sprinkler pipes are installed at the top of protective fences to spray water mist and suppress dust. However, for protective fences along roadsides, the sprayed water mist can drift outwards, wetting pedestrians walking close to the fence and affecting their normal passage. Therefore, this embodiment provides a safety protective fence for construction projects, such as... Figures 1-4 As shown, it includes a fence frame 1 and support legs installed at its bottom. The support legs are made of rubber. Several sets of elastic clips 3 are installed at intervals on the top side of the fence frame 1 to clamp the dust suppression pipe. The end of the elastic clip 3 facing away from the fence frame 1 has an opening to allow the dust suppression pipe to enter. The elastic clips 3 can be made of metal or plastic. A ventilation pipe 4 is installed horizontally through the top of the fence frame 1. Several sets of air spray pipes 5 extending out of the top of the fence frame 1 are installed vertically at the top of the ventilation pipe 4. One end of the ventilation pipe 4 extends out of the side of the fence frame 1, and the other end is connected to a flexible hose 6, which is adapted to the extension end of the ventilation pipe 4. Taking the installation of two sets of fence frames 1 as an example, one set of fence frames 1 is referred to as frame A and the other set as frame B: Frame A and frame B are placed side by side, and the flexible hose 6 on frame B is inserted into the extension end of the ventilation pipe 4 on frame A to connect the adjacent ventilation pipes 4; through the above operation, multiple ventilation pipes 4 can be connected, and then air is blown into them. The multiple sets of air spray pipes 5 on the ventilation pipes 4 blow the air upward, which can blow the water mist sprayed from the dust suppression pipe further upward, so that the water mist is dispersed at a higher position, avoiding a large amount of water mist being dispersed on the side and below the fence frame 1 and wetting pedestrians, and will not affect the normal passage of pedestrians.

[0018] To improve the stability between adjacent fence frames 1, an interlocking mechanism 2 is installed on the side of each fence frame 1. Adjacent fence frames 1 are stably connected via this interlocking mechanism 2. Specifically, the interlocking mechanism 2 includes a first connecting hole block 21 fixed to one end of each fence frame 1, and a second connecting hole block 22 offset and fixed to the other end of each fence frame 1. Bolts 23 are installed between the first connecting hole block 21 on one set of fence frames 1 and the second connecting hole block 22 on the other set of fence frames 1. Similarly, taking the installation of two sets of fence frames 1 as an example, if frames A and B are placed side by side, the first connecting hole block 21 on frame B is aligned with the second connecting hole block 22 on frame A. Figure 4 As shown, the first connecting hole block 21 and the second connecting hole block 22 are then fixed by bolts 23, thus completing the assembly of frame A and frame B, and greatly improving the stability between adjacent fence frames 1. It has the characteristics of simple structure and convenient use.

[0019] A clamping mechanism 8 is also installed on the side of the fence frame 1 at the extension end of the ventilation pipe 4 to lock the hose 6 and prevent the hose 6 from falling off. Specifically, the clamping mechanism 8 includes support seats 82 symmetrically fixed on both sides of the extension end of the ventilation pipe 4. A moving rod 83 is slidably installed through the support seats 82. An arc-shaped pressure plate 81 is fixed to the inner end of the moving rod 83. A limit plate 85 is fixed to the outer end of the moving rod 83. A tension spring 84 is sleeved on the moving rod 83 at the position between the limit plate 85 and the support seat 82. Pull the limiting plate 85 outward in advance, so that the pressure plate 81 moves outward to the appropriate position. After the hose 6 on the B frame is inserted into the extension end of the ventilation pipe 4 on the A frame, slowly release it. Under the pulling force of the tension spring 84, the limiting plate 85, the moving rod 83 and the pressure plate 81 move inward. At this time, the pressure plate 81 clamps the hose 6 under the pulling force, effectively preventing the hose 6 from falling off the extension end of the ventilation pipe 4 and improving the stability of the connection between the hose 6 and it.

[0020] Example 2 Based on Example 1, such as Figure 5 As shown, a baffle 7 is fixed at the top of the fence frame 1, and the top of the baffle 7 is curved. With this configuration, the airflow blown from the air spray pipe 5 is directed towards the interior of the construction site, thereby blowing the water mist into the construction site and effectively preventing the water mist from drifting onto the road and affecting pedestrian traffic.

[0021] Example 3 The method is basically the same as in Example 2, except that the clamping mechanism 8 is replaced with a clamping mechanism 9. In this example, the clamping mechanism 9 includes support plates 92 symmetrically fixed on both sides of the extension end of the ventilation pipe 4. A screw 93 is threaded through the support plate 92, and a clamping plate 91 is rotatably installed on the inner end of the screw 93. After the screw 93 is pre-rotated so that the clamping plate 91 moves outward to a suitable position, the hose 6 on the B frame is inserted into the extension end of the ventilation pipe 4 on the A frame. The screw 93 is reversed, and the clamping plate 91 is straightened. Finally, the clamping plates 91 on both sides are controlled to clamp the hose 6, effectively preventing the hose 6 from falling off the extension end of the ventilation pipe 4 and improving the stability of the connection between the hose 6 and the ventilation pipe 4.
