Technical Field

[0001] The present invention relates to the technical field of building construction devices, and in particular to a building construction enclosure device capable of self-adjusting wind load balance. Background Art

[0002] Construction fencing refers to measures taken to isolate the construction site from the external environment, creating a relatively enclosed space. These measures include the use of various types of shaped panels to form a protective structure. Current construction fencing typically resists wind loads by transferring the force of the wind blowing onto the shaped panels to the columns at either end, where the columns' inherent strength provides resistance. Because the columns lack support outside the plane of the fencing, they are typically designed with a relatively large cross-section, and in high winds, the construction fencing still poses a risk of being blown over.

[0018] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of the specified features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0020] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the Figure 1The orientation and position of the self-adjustable wind load balancing construction enclosure device when normally placed are shown only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] The present invention provides a construction enclosure device capable of self-adjusting wind load balance, see Figure 1-2 , including: a color plate enclosure 100, used to isolate the external environment; a steel column 200, used to support the color plate enclosure 100, and a steel structure triangular support 210 is welded on the top of the steel column 200; a fan blade 300, installed on the color plate enclosure 100, used to identify the wind force and direction; a self-balancing device 400, installed on the top of the steel column 200, linked with the fan blade 300, and adjusting the balance according to the wind force and direction.

[0023] After the fan blades 300 are driven by the wind, the self-balancing device 400 offsets the overturning moment of the wind load on the enclosure, reducing the risk of collapse. The steel structure triangular support 210 is welded to the steel column 200 to enhance the overall rigidity.

[0024] The principle of automatically generating reverse torque according to wind load to achieve self-balancing and modern intelligent control technology are used to solve technical problems such as the large cross-section of the construction fence support columns and the construction fence being easily blown down in strong wind environments. This has the technical effects of saving the cost of construction fence materials and making construction fences safer in strong wind environments.

[0025] In one embodiment, see Figure 3-6 The self-balancing device 400 includes a transmission mechanism 410, a drive wheel assembly 420, a conveyor belt 430, and a counterweight 440. One end of the transmission mechanism 410 is connected to the fan blade 300, and the other end is connected to the drive wheel assembly 420. The conveyor belt 430 is wound around the drive wheel assembly 420, and the counterweight 440 is fixed to the conveyor belt 430. The self-balancing device 400 also includes baffles 450, which are mounted on both sides of the top of the steel structure triangle support 210. The baffles 450 and the counterweight 440 are connected by springs 460.

[0026] After the fan blades 300 are driven by the wind, the counterweight 440 is driven to move through the transmission mechanism 410 to offset the overturning moment of the wind load on the enclosure and reduce the risk of collapse. The conveyor belt 430 and the drive wheel assembly 420 form a closed-loop transmission to ensure that the movement trajectory of the counterweight 440 is controllable. The wind force is converted into the displacement of the counterweight 440 through mechanical transmission to achieve automatic balance. It is completely driven by wind energy, energy-saving and environmentally friendly. The position of the counterweight 440 is automatically adjusted through gear meshing and belt transmission to offset part of the bending moment generated by the wind load. Compared with traditional construction enclosures, this innovative design not only relies on the strength of the construction enclosure structure itself to resist the bending moment of the wind load, but also can resist part of the bending moment of the wind load through this new device, so that the cross-sectional dimensions of the columns and the foundation under the columns of the construction enclosure can be made smaller and more economical, reflecting its economy.

[0027] In a windless environment, the counterweight 440 is restored to the middle position by the spring 460. It does not require electricity to operate and does not require human control. It can automatically adjust the balance according to the direction and size of the wind, reflecting its characteristics of automatic adjustment, rapid response, and strong environmental adaptability.

[0028] Exemplarily, the deformation of spring 460 is controlled within 30% of the free length, and a rubber pad is used to offset the resonant frequency of spring 460 from the natural frequency of the system by more than 30%, thereby extending the life of spring 460 and improving the durability and stability of the device.

[0029] In one embodiment, the transmission mechanism 410 includes a first transmission rod 411, a half-tooth spur gear 412, a face gear 413 and a second transmission rod 414 connected in sequence. The fan blade 300 is connected to the first transmission rod 411, and the second transmission rod 414 is connected to the transmission wheel assembly 420.

[0030] The meshing of half-tooth spur gear 412 and face gear 413 shifts the direction of rotation 90°, adapting to space-constrained enclosures. The gear train reduces speed and increases torque, ensuring smooth movement of counterweight 440. A gear-timing pulley composite transmission structure transmits wind loads from fan blades 300 to the conveyor belt. Optimized tooth profile matching enables bidirectional power transmission, improving transmission efficiency.

[0031] For example, the gears are made of 20CrMnTiH carburized steel, and the material density is improved through forging pretreatment to enhance the gears' resistance to pitting corrosion. Synthetic grease containing anti-friction additives is used, and the gear surface is regularly cleaned and evenly applied to ensure that the oil film completely covers the meshing surface, thereby extending the gear life and improving the stability and transmission efficiency of the device.

[0032] In one embodiment, a steel plate stiffening rib 211 is welded between the baffle 450 and the steel structure triangular support 210 , and the thickness of the steel plate stiffening rib 211 is not less than 8 mm.

[0033] The stiffening ribs, which are thicker than 8 mm, prevent the baffle 450 from bending or cracking under strong winds, thereby ensuring the movement stability of the counterweight 440 .

[0034] The two ends of the steel plate stiffening rib 211 are welded to the baffle 450 and the steel structure triangular brace 210, respectively, so that the stress distribution at the welding node is more uniform, thus avoiding local fracture.

[0035] In one embodiment, the transmission wheel assembly 420 includes three transmission wheels distributed in a triangle to stably tension the conveyor belt 430 .

[0036] The triangular distribution increases the belt wrap angle, preventing derailment during sudden wind changes. Three-point tensioning reduces single-point wear, extending belt life and optimizing belt drive stability.

[0037] In one embodiment, the half-tooth spur gear 412 meshes with the face gear 413. The fan blade 300 drives the first transmission rod 411 to rotate through wind pressure, thereby driving the half-tooth spur gear 412 to mesh with the face gear 413. The face gear 413 drives the second transmission rod 414, which drives the transmission wheel assembly 420 to drive the conveyor belt 430 to move.

[0038] The meshing of the half-tooth spur gear 412 and the face gear 413 shifts the rotational direction 90°, adapting to space-constrained enclosures. The gear train reduces speed and increases torque, ensuring smooth movement of the counterweight 440. The connection between the half-tooth spur gear 412 and the face gear 413 allows the position of the counterweight 440 on the conveyor belt 430 to be controlled by wind speed. Under constant wind speed, the counterweight 440 remains stably in the same position.

[0039] In one embodiment, the counterweight 440 is adjustable along the moving direction of the conveyor belt 430 to balance the forces acting on the enclosure under wind loads in different directions.

[0040] The size and direction of the wind are identified by the fan blades 300 set on the construction fence. The fan blades 300 are connected to the half-tooth spur gear 412 through a transmission rod, and then transmitted to the face gear 413, and then connected to the transmission wheel of the conveyor belt 430 through the transmission rod, controlling the counterweight 440 on the conveyor belt 430 to move left and right to offset the center of gravity, thereby offsetting the bending moment of the wind load.

[0041] The transmission wheel and the conveyor belt 430 are fixed on the steel structure triangular support 210 welded to the steel column. The counterweight 440 has springs 460 at both ends to support the baffles 450 fixed at both ends of the conveyor belt 430. When there is no wind, the counterweight 440 will rely on the springs 460 to reset.

[0042] When wind blows from one direction of the construction fence, the device will cause the conveyor belt 430 to drive the counterweight 440 to move in the opposite direction. The center of gravity offset of the counterweight 440 and the compression and extension of the spring 460 will produce a bending moment in the opposite direction to the bending moment brought by the wind load, thereby achieving the effect of resisting the wind load.

[0043] In one embodiment, half of the outer portion of the fan blade 300 is covered by the windshield housing 310 , thereby enabling the device to control the moving direction of the counterweight 440 according to the clockwise or counterclockwise rotation direction of the fan blade 300 .

[0044] The present invention provides a self-adjusting wind load balancing construction enclosure device. Compared with traditional construction enclosures, the cross-sectional dimensions of the steel columns can be made smaller, saving materials and improving safety. It requires no additional energy or human control to operate, and can automatically adjust the balance according to the direction and strength of the wind, and can also automatically restore itself. While ensuring structural safety, this device offers the advantages of convenient and economical construction.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
