Description

Technical Field

[0001] This utility model belongs to the field of wind protection, specifically relating to a windproof safety fence. Background Technology

[0002] In construction, road maintenance, and power operations, windproof safety fences serve as crucial facilities for isolation, protection, and wind environment control. Their wind resistance and service life directly impact project safety and economy. Perforated fences, made from high-strength steel plates through a perforation process, combine breathability and wind resistance. The holes divert some airflow, reducing the overall impact of wind on the fence, making them widely used in various outdoor scenarios.

[0003] However, the wind resistance of existing perforated fences mainly relies on the diversion effect of the perforations on the airflow. The solid parts of the fence without perforations are still directly subjected to wind impact. When airflow acts on the fence surface, the unperforated areas are subjected to continuous wind pressure loads. Especially in strong winds or gusts, this local impact force will form periodic alternating stress, which will repeatedly act on the metal plates, connecting nodes, and supporting structures of the fence. Over long-term use, this will cause fatigue damage to the fence materials. Micro-cracks are prone to develop inside the metal plates and continue to expand. Bolts, rivets, and other connectors will loosen or deform due to continuous stress. The connection strength between the support poles and the base will also decrease with the number of impacts. This material fatigue and structural damage caused by the direct impact of wind on the unperforated areas not only reduces the wind resistance stability of the perforated fence and shortens its actual service life, but may also cause the fence to deform locally, break, or even overturn completely in strong winds, posing a threat to the safety of people and property in the surrounding area.

[0004] Therefore, there is an urgent need to develop a windproof safety fence that can further optimize wind load distribution, reduce local impact stress, and improve wind resistance and durability. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention incorporates a windproof mechanism. When wind blows onto the fence surface, some airflow is blocked by the semi-cylindrical frame on the outside. A small portion of the airflow that reaches the outside of the semi-cylindrical frame travels along the outer arc of the frame to the surface of the rotating plate above it. The remaining airflow directly hits the rotating plate, causing it to rotate. Simultaneously, the circular shaft rotates within the rotating hole, and the rotating plate rotates within the semi-cylindrical frame. This transfers the kinetic energy of the wind to the rotating plate, converting it into its own kinetic energy. This design not only provides wind protection but also reduces the impact of wind on the fence, preventing material fatigue and structural damage caused by prolonged direct wind impact.

[0019] This invention utilizes a counterweight unit to slide the counterweight block to the outside of a rectangular rod. A second bolt is then passed through a mounting hole and threaded into a corresponding threaded hole. The lower side of the bolt's head contacts the upper outer side of the counterweight block, thus fixing the counterweight block to the outer end of the rectangular rod. Different numbers of counterweight blocks can be installed at the outer end of the rectangular rod, resulting in varying wind forces required for the rotating plate to rotate. This allows for the installation of appropriate counterweights at the outer end of the rectangular rod based on the wind conditions in the area where the safety fence is installed, maximizing wind power dissipation and increasing the usability of the safety fence.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This specific embodiment is a windproof safety fence, and its structural diagram is shown below. Figures 1 to 4 As shown, the device includes a column 1, a mounting plate 2 welded to the lower end of the column 1, a sealing plate 3 at the front end of the column 1, and a first bolt 4 at the left end of the sealing plate 3. The column 1 is hollow inside, with a threaded groove at the middle position on the left side of the front end of the column 1. A circular hole is formed at the middle position on the left side of the sealing plate 3. The outer side of the first bolt 4 is slidably connected to the inner side of the circular hole, and the rear end of the outer side of the first bolt 4 is threadedly connected to the inner side of the threaded groove. The front right side of the column 1 is hinged to the right side of the first bolt 4. Thus, by rotating the first bolt 4 to the front end of the column 1, then passing the first bolt 4 through the circular hole and threading it into the threaded groove, and with the threaded head of the first bolt 4 contacting the front side of the first bolt 4, the first bolt 4 can be fixed to the front end of the column 1, sealing the interior of the column 1.

[0029] A windproof mechanism is provided between the columns 1, and the windproof mechanism includes a semi-cylindrical frame 501 fixedly connected between the columns 1. A circular shaft 502 is connected inside the semi-cylindrical frame 501. A rotating hole is opened at the middle position of the upper part of the left and right ends of the semi-cylindrical frame 501. The outer sides of the left and right ends of the circular shaft 502 are rotatably connected to the inner side of the rotating hole. Rotating plates 503 are fixedly connected at equal intervals to the outer side of the circular shaft 502. The left and right sides of the rotating plates 503 are slidably connected to the left and right ends of the inner side of the semi-cylindrical frame 501. The outer end of the rotating plates 503 away from the circular shaft 502 is slidably connected to the inner side of the semi-cylindrical frame 501. Therefore, when the wind blows onto the surface of the fence, some of the airflow is blown to the outside of the semi-cylindrical frame 501 and blocked by the semi-cylindrical frame 501. At the same time, a small portion of the airflow blowing to the outside of the semi-cylindrical frame 501 will be blown along the outer arc surface of the semi-cylindrical frame 501 to the surface of the rotating plate 503 above the semi-cylindrical frame 501. The other part of the airflow blows directly to the surface of the rotating plate 503, causing the rotating plate 503 to flip. At the same time, the circular shaft 502 rotates in the rotating hole, and the rotating plate 503 rotates in the semi-cylindrical frame 501. This allows the kinetic energy of the wind to be transferred to the rotating plate and converted into the kinetic energy of the rotating plate. This can reduce the impact of the wind on the fence while preventing wind, and avoid material fatigue and structural damage caused by long-term direct wind impact.

[0030] In addition, the rotating plate 503 has vents evenly spaced inside. When wind blows onto the surface of the rotating plate 503, the vents inside the rotating plate 503 can divert some of the wind force, reduce the wind load, and further reduce the impact of the wind on the fence.

[0031] Cooperate Figure 5As shown, a counterweight unit is installed inside the column 1. The counterweight unit includes a rectangular rod 601 fixedly connected to the right end of the round shaft 502. A counterweight block 602 is connected to the outer end of the rectangular rod 601, and a second bolt 603 is connected to the upper end of the counterweight block 602. Through holes are evenly spaced on the left end of the column 1. The outer side of the left end of the rectangular rod 601 is rotatably connected to the inner side of the through holes. A rectangular hole is opened inside the upper end of the counterweight block 602, and the outer side of the rectangular rod 601 is slidably connected to the inner side of the rectangular hole. A through mounting hole is opened at the middle position of the upper end of the through holes inside the counterweight block 602. Threaded holes are evenly spaced inside the rectangular rod 601. By sliding the counterweight 602 to the outside of the rectangular rod 601, and then threading the second bolt 603 through the mounting hole and connecting it to the corresponding threaded hole, with the lower side of the bolt head of the second bolt 603 contacting the upper outer side of the counterweight 602, the counterweight 602 can be fixed to the outer end of the rectangular rod 601. Different numbers of counterweights 602 can be installed at the outer end of the rectangular rod 601, thus requiring different wind forces when the rotating plate 503 rotates. This allows for the installation of counterweights 602 of appropriate weight at the outer end of the rectangular rod 601 based on the wind force in the area where the safety fence is installed, enabling the rotating plate 503 to consume wind force to the maximum extent and increasing the usability of the safety fence.

[0032] Working principle: When the complete fence is used for wind protection, the wind blows to the surface of the fence. Some of the airflow blows to the outside of the semi-cylindrical frame 501 and is blocked by the semi-cylindrical frame 501. At the same time, a small part of the airflow blows to the outside of the semi-cylindrical frame 501 along the outer arc surface of the semi-cylindrical frame 501 and blows to the surface of the rotating plate 503 above the semi-cylindrical frame 501. The other part of the airflow blows directly to the surface of the rotating plate 503, causing the rotating plate 503 to flip. At the same time, the circular shaft 502 rotates in the rotating hole, and the rotating plate 503 rotates in the semi-cylindrical frame 501. This allows the kinetic energy of the wind to be transferred to the rotating plate and converted into the kinetic energy of the rotating plate. While protecting against the wind, it also reduces the impact force of the wind on the fence.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
