Description

Technical Field

[0001] This invention relates to the field of construction site enclosure technology, specifically to an environmentally friendly enclosure structure for green construction based on BIM. Background Technology

[0002] Building Information Modeling (BIM) technology, also known as Building Information Modeling, is a key technology for the digital transformation of the construction industry. It has been widely applied to the design, construction, and operation and maintenance management of engineering projects throughout their entire lifecycle. By constructing a multi-dimensional data model that includes geometric, temporal, cost, and environmental information, BIM technology enables the visualization, collaborative management, and refined control of engineering projects. In the field of green construction, BIM technology can be used for optimizing construction site layout, simulating construction progress, analyzing resource consumption, and assessing environmental impact, providing strong support for scientific decision-making during the construction process. Construction site fencing, as a physical barrier between the construction site and the external environment, is an important engineering measure to ensure construction safety, control dust spread, reduce noise transmission, and maintain the appearance of the city. Existing environmentally friendly construction site fencing mechanisms, such as the one disclosed in publication number CN217501295U, involve screwing different movable baffles into the fencing frame to adjust the overall area of ​​the movable baffles and the fencing frame, thus adapting to different fencing needs. When the fencing frame is about to collapse under external force, a swing block first swings out from inside the mounting frame to brace against the ground, preventing and delaying the complete collapse of the fencing frame and warning people. When it is necessary to spray water to suppress dust, the water inlet pipe is connected to a water source, the water pump is started, and water is sprayed through the nozzles to suppress dust. Furthermore, by starting a servo motor to drive the lead screw to rotate forward or backward, the nozzles can move left and right, thereby increasing the area of ​​water spraying. When the above-mentioned prior art is used, the nozzle can only move back and forth, and the rotation is restricted, resulting in a fixed spray height, which is not conducive to improving dust reduction efficiency. In addition, when the above-mentioned existing technology is used, the reciprocating movement of the nozzle relies on the motor drive. However, the dust concentration in the construction environment is high. The motor is prone to failure due to dust accumulation, heat dissipation obstruction and other factors when it is in this environment for a long time, which makes it impossible for the nozzle to reciprocate stably and continuously. Therefore, a BIM-based, environmentally friendly construction site enclosure mechanism is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide an environmentally friendly enclosure mechanism for green construction based on BIM, in order to solve the problems mentioned in the background art, such as the existing enclosure mechanism having a fixed spray height and limited dust reduction efficiency because the spray head can only move back and forth and cannot swing back and forth, and the spray head's reciprocating movement relying on motor drive, which is prone to failure and consumes a lot of energy in dusty environments, which is not conducive to energy conservation and environmental protection.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An environmentally friendly construction site enclosure mechanism based on BIM includes supporting steel columns and matching baffles. The supporting steel columns have slots on both sides, and the two ends of the baffles are movably engaged with the slots on the sides of adjacent supporting steel columns. The upper surface of the baffles has protrusions, and the lower surface has matching recesses. Adjacent baffles are joined by the engagement of the protrusions and recesses. The upper ends of two adjacent supporting steel columns are fixedly connected to a mounting frame via a plug-in mechanism. The plug-in mechanism includes a groove at the upper end of the supporting steel column, with a slot within the groove. The mounting frame is equipped with a reciprocating spray dust suppression mechanism, which includes a single-rotation reciprocating screw fixedly connected to the mounting frame. The mounting frame also has a guide rod parallel to the single-rotation reciprocating screw, and torsion springs are provided between the two ends of the guide rod and the mounting frame to reset the guide rod.

[0005] Preferably, the insertion mechanism further includes a plug strip fixedly connected to the lower surface of the end of the mounting bracket, and the structure and size of the plug strip and the slot are matched. The end side of the mounting bracket is provided with a fixing hole penetrating through both sides, and the upper end of the mounting bracket is provided with a through hole penetrating through both sides. The position and size of the through hole and the fixing hole are matched, so that the bolt passes through the through hole and the fixing hole and then the nut is threadedly connected, thereby driving the mounting bracket to be stably fixed on the supporting steel column.

[0006] Preferably, the reciprocating spray dust suppression mechanism further includes a nut sleeve threaded to the outside of a single-turn reciprocating screw, and an atomizing nozzle is connected to the outside of the nut sleeve via a one-way bearing.

[0007] Preferably, a mounting base is provided between the single-rotation reciprocating screw and the guide rod, and the mounting base is n-shaped. The lower end of the mounting base is positioned across the guide rod, and two guide wheel assemblies are provided at the lower end of the mounting base. The two guide wheel assemblies are respectively tumblingly connected to the upper and lower surfaces of the guide rod.

[0008] Preferably, a piston rod is coaxially fixedly connected to the upper surface of the mounting base, and a piston tube is provided above the mounting base. The upper end of the piston rod extends into the interior of the piston tube, and the upper end of the piston rod is connected to the inner wall of the piston tube in a seamless sliding connection. A sleeve is coaxially fixedly connected to the outer side of the piston tube, and a piston cavity is formed between the inner side of the sleeve and the outer side of the piston tube. The upper end of a piston ring is seamlessly slidably connected to the inner side of the lower end of the piston cavity between the sleeve and the piston tube, and the lower end of the piston ring is coaxially fixedly connected to the upper surface of the mounting base.

[0009] Preferably, a mounting plate coaxial with the lower end of the sleeve is fixedly connected to the outer side of the sleeve, and the lower surface of the mounting plate is completely overlapped with the upper surface of the mounting base in the vertical direction. A limiting tube perpendicular to the lower surface of the mounting plate is fixedly connected to each of the four corners of the lower surface of the mounting plate, and the upper end of a limiting rod that matches the limiting tube is movably inserted into the limiting tube. The lower end of the limiting rod is fixedly connected to the upper surface of the mounting base, and a spring sleeved on the outer side of the corresponding limiting rod is provided between the upper surface of the mounting base and the lower end of the limiting tube.

[0010] Preferably, the piston tube has overflow holes extending through both sides, and the overflow holes are set at equal angles with respect to the axis of the piston tube. The overflow holes extend through the interior of the piston tube and the piston cavity between the sleeve and the piston tube.

[0011] Preferably, the upper end of the piston tube is axially connected to the tail end of the atomizing nozzle, and a water injection hole penetrating into the interior of the piston tube is provided on the upper side of the piston tube, and a sealing block is provided at the outer end opening of the water injection hole.

[0012] Preferably, the upper side of the sleeve is provided with a water inlet hole that runs through both sides, and the water inlet hole is connected to the water pump through a water supply pipe. The lower side of the piston ring is provided with a strip-shaped through hole that runs through both sides. The piston rod is provided with a one-way water supply channel that runs through both sides, and the one-way water supply channel is connected to the atomizing nozzle through a water guide pipe. The water guide pipe runs through the strip-shaped through hole.

[0013] Preferably, the upper opening of the one-way water conveying channel is funnel-shaped, and a one-way valve is provided at the bottom of the funnel shape to allow liquid to pass through the one-way water conveying channel in only one direction. The upper end of the one-way water conveying channel is positioned opposite to the internal opening of the water injection hole.

[0014] Compared with existing technologies, the beneficial effects of this invention are: When performing dust suppression spraying, the atomizing nozzles of this BIM-based green construction environmentally friendly fencing mechanism can not only move back and forth but also oscillate back and forth, thereby expanding the spraying coverage area and improving dust suppression efficiency. Furthermore, the reciprocating movement and oscillation of the atomizing nozzles do not rely on motor drives, avoiding the problem of motor malfunction in dusty environments. This ensures continuous and stable spraying operations, while reducing energy consumption and contributing to energy conservation and environmental protection. 1. Water is continuously pumped into the piston chamber between the sleeve and the piston tube via a water pump and water pipe, increasing the pressure inside the piston chamber. This causes the upper end of the piston ring to move downward relative to the sleeve. Since the piston ring and piston rod are connected by a mounting seat, they will move downward synchronously relative to the entire assembly formed by the sleeve and piston tube. When the piston rod moves downward relative to the piston tube, a negative pressure will be formed inside the piston tube. During the above process, the limiting rod gradually extends into the limiting tube, causing the spring to be stretched. When the interior of the piston chamber and the piston tube can be connected through the overflow hole, the water in the piston chamber will be instantly sucked into the piston tube. Subsequently, under the reset action of the spring, the piston ring and piston rod reset. During the piston rod reset process, a positive pressure will be formed inside the piston tube, which will squeeze the excess water into the one-way water delivery channel and deliver it to the atomizing nozzle through the water guide pipe. The entire process is carried out in a high-frequency cycle, which allows the atomizing nozzle to spray atomized water vapor in a high-frequency intermittent manner, using atomized water vapor to achieve dust suppression. 2. Because the piston ring and piston rod move downward relative to the whole formed by the sleeve and piston tube, the whole formed by the sleeve and piston tube can move upward relative to the whole formed by the piston ring, piston rod and mounting base. Through the shaft connection between the piston tube and the atomizing nozzle, and the self-resetting bearing connection between the guide rod and the mounting bracket, the atomizing nozzle can swing back and forth, thereby expanding the spray coverage area and helping to improve dust reduction efficiency. 3. Since the atomizing nozzle reciprocates, the nut sleeve can rotate unidirectionally with the atomizing nozzle via a one-way bearing. This allows the nut sleeve to rotate intermittently at a high frequency. Combined with its threaded connection to the single-turn reciprocating screw, the nut sleeve can move back and forth on the single-turn reciprocating screw, thereby driving the atomizing nozzle to move back and forth. Since the reciprocating movement of the atomizing nozzle does not require a motor drive, it avoids the problem of motor failure in dusty environments that could lead to unstable spraying. At the same time, it reduces energy consumption and is beneficial for energy conservation and environmental protection. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To address the problem that while sprinklers on construction site hoardings can move back and forth, they cannot swing back and forth, resulting in a constant spray height and thus failing to enhance dust suppression, the following technical solution is provided: a BIM-based environmentally friendly hoarding mechanism for green construction, comprising supporting steel columns 1 and matching baffles 2. Both sides of the supporting steel columns 1 are provided with slots 7, and both ends of the baffles 2 are movably engaged with the slots 7 on the sides of adjacent supporting steel columns 1. The upper surface of the baffles 2 is provided with protrusions, and... The lower surface of the baffle 2 is provided with a concave hole that matches the protrusion. The upper and lower adjacent baffles 2 are spliced ​​together by the engagement of the protrusion and the concave hole. The upper ends of two adjacent supporting steel columns 1 are fixedly connected to the mounting frame 3 by a plug-in mechanism. The plug-in mechanism includes a groove provided on the upper end of the supporting steel column 1, and a slot 12 is provided in the groove. The mounting frame 3 is provided with a reciprocating spray dust suppression mechanism. The reciprocating spray dust suppression mechanism includes a guide rod 5 connected to the bearing on the mounting frame 3. Torsion springs are provided between the two ends of the guide rod 5 and the mounting frame 3 to reset the guide rod 5.

[0019] In a preferred embodiment of the invention, the insertion mechanism further includes an insert 10 fixedly connected to the lower surface of the end of the mounting bracket 3, and the structure and size of the insert 10 and the slot 12 are matched. The end side of the mounting bracket 3 is provided with a fixing hole 11 penetrating through both sides, and the upper end of the mounting bracket 3 is provided with a through hole 13 penetrating through both sides, and the position and size of the through hole 13 and the fixing hole 11 are matched, so that the bolt passes through the through hole 13 and the fixing hole 11 and then the nut is threadedly connected, thereby driving the mounting bracket 3 to be stably fixed on the supporting steel column 1.

[0020] In the above technical solution, the support steel column 1 can be stably connected to the mounting frame 3 by the engagement of the insert 10 and the slot 12, and by the bolt passing through the through hole 13 and the fixing hole 11 and then locking it with a nut.

[0021] In a preferred embodiment of the invention, a mounting base 9 is provided above the guide rod 5, and the mounting base 9 is n-shaped. The lower end of the mounting base 9 is positioned across the guide rod 5, and two guide wheel assemblies 18 are provided at the lower end of the mounting base 9. The two guide wheel assemblies 18 are respectively tumblingly connected to the upper and lower surfaces of the guide rod 5.

[0022] In the above technical solution, the mounting base 9 and the guide wheel assembly 18 thereon can facilitate the stable movement of the upper structure of the mounting base 9 along the axial direction of the guide rod 5.

[0023] In a preferred embodiment of the invention, a piston column 25 is coaxially fixedly connected to the upper surface of the mounting base 9, and a piston tube 19 is provided above the mounting base 9. The upper end of the piston column 25 extends into the interior of the piston tube 19 (there is a gap between the outer side of the piston column 25 and the lower end of the piston tube 19, which is not sealed), and the upper end of the piston column 25 is connected to the inner wall of the piston tube 19 by a seamless sliding connection. A sleeve 20 is coaxially fixedly connected to the outer side of the piston tube 19, and a piston cavity is formed between the inner side of the sleeve 20 and the outer side of the piston tube 19. The upper end of a piston ring 29 is seamlessly slidably connected to the inner side of the lower end of the piston cavity between the sleeve 20 and the piston tube 19, and the lower end of the piston ring 29 is coaxially fixedly connected to the upper surface of the mounting base 9.

[0024] In the above technical solution, the piston rod 25 and piston ring 29 can move synchronously in the piston tube 19 and piston chamber, respectively.

[0025] In a preferred embodiment of the invention, a mounting plate 14 coaxial with the lower end of the sleeve 20 is fixedly connected to the outer side of the sleeve 20, and the lower surface of the mounting plate 14 is completely overlapped with the upper surface of the mounting base 9 in the vertical direction. A limiting tube 21 perpendicular to the lower surface of the mounting plate 14 is fixedly connected to each of the four corners of the lower surface of the mounting plate 14, and the upper end of the limiting rod 22 that matches the limiting tube 21 is movably inserted into the limiting tube 21. The lower end of the limiting rod 22 is fixedly connected to the upper surface of the mounting base 9, and a spring 23 sleeved on the outer side of the corresponding limiting rod 22 is provided between the upper surface of the mounting base 9 and the lower end of the limiting tube 21.

[0026] In the above technical solution, it is easy to install the spring 23, which helps the piston rod 25 and piston ring 29 to return to their original position under the action of the spring 23.

[0027] In a preferred embodiment of the invention, the piston tube 19 is provided with overflow holes 30 that pass through both sides of it, and the overflow holes 30 are set at equal angles with respect to the axis of the piston tube 19. The overflow holes 30 pass through the interior of the piston tube 19 and the piston cavity between the sleeve 20 and the piston tube 19.

[0028] In the above technical solution, when the overflow hole 30 connects the piston tube 19 and the piston chamber, it facilitates the instantaneous intake of water in the piston chamber into the piston tube 19.

[0029] In a preferred embodiment of the invention, the upper end of the piston tube 19 is axially connected to the tail end of the atomizing nozzle 6, and a water injection hole 27 extending into the interior of the piston tube 19 is provided on the upper side of the piston tube 19, with a sealing block 28 provided at the outer end opening of the water injection hole 27.

[0030] In the above technical solution, the piston tube 19 is axially connected to the atomizing nozzle 6, so that the piston tube 19 drives the atomizing nozzle 6 to swing when it reciprocates, and water can be injected into the upper end of the one-way water supply channel 26 in advance through the water injection hole 27, thereby completing the liquid seal.

[0031] In a preferred embodiment of the invention, the upper side of the sleeve 20 is provided with a water inlet hole that runs through both sides, and the water inlet hole is connected to the water pump through the water supply pipe 15. The lower side of the piston ring 29 is provided with a strip-shaped through hole 24 that runs through both sides. The piston rod 25 is provided with a one-way water supply channel 26 that runs through both sides, and the one-way water supply channel 26 is connected to the atomizing nozzle 6 through the water guide pipe 16. The water guide pipe 16 is provided through the strip-shaped through hole 24.

[0032] In the above technical solution, water can be continuously injected into the piston chamber through the water pump and water pipe 15, thereby increasing the pressure in the piston chamber so as to drive the piston ring 29 and piston column 25 to move down synchronously. In addition, during the resetting process of piston column 25, some water in piston tube 19 can be forced into one-way water supply channel 26 and transported to atomizing nozzle 6 through water guide pipe 16 for spraying.

[0033] In a preferred embodiment of the invention, the upper opening of the one-way water delivery channel 26 is funnel-shaped, and a one-way valve is provided at the bottom of the funnel shape to allow liquid to pass through the one-way water delivery channel 26 in only one direction. The upper end of the one-way water delivery channel 26 is positioned opposite to the internal opening of the water injection hole 27.

[0034] In the above technical solution, the funnel-shaped structure facilitates water storage, achieves liquid sealing, and prevents air in the piston tube 19 from being discharged through the one-way water delivery channel 26.

[0035] according to Figures 1-3 as well as Figures 5-10 When in use, first open the sealing block 28 and inject some water into the piston tube 19 through the water injection hole 27. This water will flow into the funnel-shaped structure of the one-way water supply channel 26 to form a liquid seal. Then close the sealing block 28 to form a sealed space inside the piston tube 19. Then the water supply pipe 15 is connected to an external water pump, and the water pump continuously and stably injects water into the piston chamber between the piston pipe 19 and the sleeve 20. As the water in the piston chamber increases, the internal pressure increases, which in turn squeezes the piston ring 29 to move downward. Since the piston ring 29 and piston rod 25 are both fixed on the mounting base 9, and the mounting base 9 is connected to the guide rod 5 through the guide wheel assembly 18, the piston ring 29 and piston rod 25 cannot move downward, which will cause the piston tube 19 and sleeve 20 to move upward. When the piston tube 19 and the sleeve 20 move upward, a negative pressure is gradually formed inside the piston tube 19, and the limiting rod 22 gradually extends into the limiting tube 21, and the spring 23 is gradually stretched. After the piston tube 19 and sleeve 20 move up to the overflow hole 30 to connect the piston tube 19 and the piston chamber, the water in the piston chamber will be sucked into the piston tube 19 in an instant because the piston tube 19 is under negative pressure. After this, the spring 23 immediately returns to its original position, causing the piston ring 29 and piston rod 25 to return to their original positions. During the resetting process of piston column 25, positive pressure is formed in piston tube 19, which squeezes the water in piston tube 19, causing the water in piston tube 19 to be squeezed into one-way water delivery channel 26 and then delivered to atomizing nozzle 6 through water guide pipe 16 for spraying. During the above process, the atomizing nozzle 6 will complete one swing, and during the swing, it will spray atomized water vapor to suppress dust. This method can enhance the effect of spraying to suppress dust. The above process is repeated cyclically, which allows the atomizing nozzle 6 to oscillate continuously. In addition, the intervals between the reciprocating motions are small, thus enabling the atomizing nozzle 6 to oscillate at a high frequency, which helps to ensure the continuity of spraying.

[0036] Example 2: To solve the problem in Example 1 that the atomizing nozzle 6 requires motor drive when it moves back and forth, the following technical solution is provided: The reciprocating spray dust suppression mechanism includes a single-rotation reciprocating screw 4 fixedly connected to the mounting frame 3, and the single-rotation reciprocating screw 4 and the guide rod 5 are arranged parallel to each other.

[0037] In a preferred embodiment of the invention, the reciprocating spray dust suppression mechanism further includes a nut sleeve 17 threaded to the outside of the single-turn reciprocating screw 4, and an atomizing nozzle 6 is connected to the outside of the nut sleeve 17 via a one-way bearing 8.

[0038] In the above technical solution, the one-way bearing 8 enables the nut sleeve 17 to rotate intermittently during the reciprocating swing of the atomizing nozzle 6, thereby achieving the purpose of reciprocating movement of the nut sleeve 17 on the single-turn reciprocating screw 4, which helps the atomizing nozzle 6 to reciprocate along the axial direction of the single-turn reciprocating screw 4.

[0039] according to Figure 4 When the atomizing nozzle 6 reciprocates at high frequency, the nut sleeve 17 can be driven to rotate intermittently in one direction at high frequency through the one-way bearing 8. Combined with its threaded connection with the single-turn reciprocating screw 4, the nut sleeve 17 can move back and forth on the single-turn reciprocating screw 4. During the above process, the atomizing nozzle 6 will not only move back and forth along the axis of the single-rotation reciprocating screw 4, but will also swing back and forth, which helps to improve the efficiency of dust suppression. In addition, the above process does not rely on motors, which avoids the problem of motor failure in complex construction environments and also reduces energy consumption, thus contributing to energy conservation and environmental protection.

[0040] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
