Abstract
Description
Technical Field
[0001] This application relates to the field of coal mine production technology, and in particular to a dust control device. Background Technology
[0002] In construction scenarios such as coal mining, large amounts of dust are often generated. Current technologies often employ single dust control methods, resulting in incomplete dust dispersion control. Furthermore, these dust control devices are structurally complex, occupy a large amount of space, and are difficult to install or store quickly in narrow, confined spaces such as tunnels. Utility Model Content
[0003] This application is made in view of the above-mentioned problems. This application provides a dustproof device.
[0004] According to one aspect of this application, a dustproof device is provided, comprising:
[0005] The system includes a supporting spray structure, a dustproof structure, a transverse chute, multiple clamping structures, multiple sliding connectors, and multiple counterweights. Each clamping structure is located at both ends of the supporting spray structure for connecting to the object to be fixed. The dustproof structure includes multiple dustproof nets, with adjacent dustproof nets rotatably connected. The transverse chute is located on the side of the supporting spray structure facing the dustproof nets. One end of each sliding connector has a slider that is slidably connected to the chute. The other end of each sliding connector is connected to the dustproof net. Each counterweight is located on the side of each dustproof net away from the sliding connector.
[0006] Compared with existing technologies, the dustproof device provided in this application includes a supporting spray structure, a dustproof structure, a transverse chute, multiple clamping structures, multiple sliding connectors, and multiple counterweights. Each clamping structure is located at both ends of the supporting spray structure and is fixed to the object to be fixed, ensuring stable installation. The dustproof structure includes multiple dustproof nets, with adjacent nets rotatably connected, allowing for overall folding or unfolding to adapt to different space requirements. The supporting spray structure serves as the skeleton of the entire device, bearing the weight of components such as the dustproof nets and sliding connectors. The transverse chute is located on the side of the supporting spray structure facing the dustproof nets. Each sliding connector has a slider at one end, which is slidably connected to the transverse chute. The transverse chute provides a sliding track for the slider, enabling the folding and unfolding of the dustproof nets. Manual pushing or pulling forces can be applied to the dustproof nets to adjust their position. Each counterweight is located on the side of each dustproof net away from the sliding connector, maintaining the dustproof nets vertically and horizontally through gravity, preventing the nets from swaying due to airflow or operational shaking, thus ensuring effective dustproofing. When installing the dust suppression device, the supporting spray structure is fixed to the object to be fixed using a clamping structure, ensuring the horizontal chute is level. The sliding block of the sliding connector pushes the dust net to unfold along the chute. Adjacent dust nets are connected by rotation to unfold into a continuous plane, covering the area requiring dust protection. After the dust net is unfolded, the counterweight pulls the net down by gravity, keeping it vertical and preventing tilting or swaying. Next, the supporting spray structure sprays the dust net to further reduce dust, creating a dual effect of physical isolation and mist dust suppression. When vehicles, pedestrians, or equipment maintenance are required, the supporting spray structure stops spraying. At this time, the dust net can be manually pushed to one side, causing the sliding block of the sliding connector to slide along the chute to one end, folding the entire dust net. When vehicle, pedestrian, or equipment maintenance is finished, the dust net is pushed in the opposite direction, the sliding block returns to its initial position along the chute, the dust net unfolds again to full coverage, the counterweight straightens the net again, and spraying resumes.
[0007] It is evident that the dustproof device provided in this application can effectively control dust diffusion and can be quickly installed or stored in various installation spaces.
[0008] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0012] Figure 3 A schematic diagram of the clamping structure according to an embodiment of this application is shown. Detailed Implementation
[0013] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.
[0014] In construction scenarios such as coal mining, large amounts of dust are often generated. Current technologies often employ single dust control methods, resulting in incomplete dust dispersion control. Furthermore, these dust control devices are structurally complex, occupy a large amount of space, and are difficult to install or store quickly in narrow, confined spaces such as tunnels.
[0015] To address the aforementioned issues, this application provides a dustproof device with a simple structure that can effectively control dust diffusion and can be quickly installed or stored in various installation spaces. Figure 1 A schematic diagram of the structure of a dustproof device according to an embodiment of this application is shown. Figure 2 A schematic diagram of the transverse slide groove according to an embodiment of this application is shown. Figure 1 and Figure 2 As shown, the dustproof device includes a supporting spray structure 1, a dustproof structure 2, a transverse chute 3, multiple clamping structures 4, multiple sliding connectors 5, and multiple counterweights 6. Each clamping structure 4 is respectively set at both ends of the supporting spray structure 1 for connecting with the object to be fixed. The dustproof structure 2 includes multiple dustproof nets 201, with two adjacent dustproof nets 201 rotatably connected. The transverse chute 3 is set on the side of the supporting spray structure 1 facing the dustproof nets 201. One end of each sliding connector 5 is provided with a slider 501, which is slidably connected to the transverse chute 3. The other end of each sliding connector 5 is connected to the dustproof net 201. Each counterweight 6 is set on the side of each dustproof net 201 away from the sliding connector 5.
[0016] In practice, the supporting spray structure 1 is fixed to the object to be fixed by the clamping structure 4, ensuring that the transverse chute 3 is horizontal. The slider 501 of the sliding connector 5 pushes the dustproof net 201 to unfold along the chute. Adjacent dustproof nets 201 are connected by rotation to unfold into a continuous plane, covering the area requiring dust protection. After the dustproof net 201 is unfolded, the counterweight 6 pulls it down by gravity, keeping it vertical and preventing tilting or drifting. Next, the supporting spray structure 1 sprays the dustproof net 201 to further reduce dust, creating a dual effect of physical isolation and dust suppression. When vehicles, pedestrians, or equipment need to pass or require maintenance, the supporting spray structure 1 stops spraying. At this time, the dustproof net 201 can be manually pushed to one side, and the slider 501 of the sliding connector 5 slides along the transverse chute 3 to one end, causing the dustproof net 201 to fold as a whole. When vehicles, pedestrians, or equipment maintenance are completed, the dust net 201 is pushed in the reverse direction, the slider 501 returns to its initial position along the transverse groove 3, the dust net 201 is re-expanded to cover the entire cross section, the counterweight 6 straightens the net body again, and the spraying begins.
[0017] It is evident that the dustproof device provided in this application can effectively control dust diffusion and can be quickly installed or stored in various installation spaces.
[0018] It should be understood that the object to be fixed can be the walls on both sides of the alley, the roof support, or other objects to be fixed, and there is no limitation here.
[0019] In one alternative approach, such as Figure 1 and Figure 2 As shown, the supporting spray structure 1 in this embodiment includes a support rod 101 and a plurality of nozzles 102. A transverse groove 3 is provided on the side of the support rod 101 facing the dustproof net 201. A spray liquid channel is provided inside the support rod 101. An opening 1011 for spray liquid to flow in is opened on the side of the support rod 101 away from the dustproof net 201. The opening 1011 is connected to the spray liquid channel. A plurality of nozzles 102 are provided in the transverse groove 3. The spray liquid channel is connected to the nozzles 102.
[0020] The support rod 101 serves as the main support for the spray structure 1, bearing the weight of the transverse chute 3, nozzles 102, and dustproof net 201. An opening 1011 for the spray liquid to flow into the support rod 101, which is opposite to the dustproof net 201, is provided. The opening 1011 communicates with the spray liquid channel, allowing external spray liquid to be transported into the channel. Multiple nozzles 102 are housed within the transverse chute 3 to prevent damage from external impacts, while the chute structure optimizes the spray diffusion path. It should be understood that the support rod 101 can be a stainless steel or aluminum alloy support rod with sealed ends, and adjustments can be made according to actual conditions; no limitation is made here. The spray angle of the nozzle 102 can be 60° to 90°, and adjustments can be made according to actual conditions; no limitation is made here.
[0021] In practice, external water flows into the spray liquid channel through opening 1011. The spray liquid flows within the channel, and the pressure is balanced by the uniformity of the channel's cross-section, ensuring consistent flow rates at each nozzle 102. The spray liquid is ejected at high speed through nozzles 102, breaking into droplets under aerodynamic force, forming a cone-shaped spray area covering the area in front of the dustproof net 201. During dust suppression, dust falls into the dustproof net 201. Large dust particles are directly intercepted by the net, while fine droplets in the spray area collide with the dust, causing the dust to become moistened and agglomerated through inertial collisions and Brownian diffusion. The moistened dust settles faster due to its increased weight, with some being captured by the net and some falling directly to the ground. When the dustproof net 201 is folded, the external water flow into the spray liquid channel stops, thus stopping the spraying operation. When the net 201 is unfolded, the external water flow back into the spray liquid channel, resuming the spraying operation.
[0022] In practical applications, a controllable valve can be installed on the external water supply pipeline to control whether the external water source flows into the opening 1011.
[0023] For example, such as Figure 1 and Figure 2 As shown, in this embodiment, the nozzles 102 are evenly spaced along the extension direction of the transverse groove 3. The droplets sprayed from each nozzle 102 form a water curtain of uniform thickness in front of the dustproof net 201, avoiding droplet accumulation caused by the dense concentration of local nozzles 102. It should be understood that the spray angle and diameter of the nozzles 102 should be uniform, and the specific values can be adjusted according to the actual situation, which is not limited here.
[0024] Figure 3 A schematic diagram of the clamping structure according to an embodiment of this application is shown. Figure 1 and Figure 3As shown, the clamping structure 4 in this embodiment includes a fixed frame 401, a threaded rod 402, a pressure plate 403, and a locking nut 404. The outer side wall of the fixed frame 401 is connected to the end of the supporting spray structure 1, and the inner side wall of the fixed frame 401 faces the object to be fixed. One end of the fixed frame 401 is provided with a through hole 405 for accommodating the threaded rod 402. The threaded rod 402 includes a first end facing the inner side wall of the fixed frame 401 and a second end facing away from the outer side wall of the fixed frame 401. The pressure plate 403 is connected to the first end, and the locking nut 404 is sleeved on the second end.
[0025] The fixed frame 401 serves as the main frame of the clamping structure 4, providing an installation reference for components such as the threaded rod 402 and the pressure plate 403. Its inner wall directly adheres to the object to be fixed, achieving initial positioning and ensuring that the clamping direction is perpendicular to the object's axis. A through hole 405 at one end provides a moving track for the threaded rod 402, allowing it to slide axially while limiting radial wobble. The first end of the threaded rod 402 is connected to the pressure plate 403. By rotating the threaded rod 402, the distance between the pressure plate 403 and the inner wall of the fixed frame 401 can be adjusted to accommodate objects of different sizes. The pressure plate 403 converts the concentrated force of the threaded rod 402 into a surface contact force, preventing indentations or damage to the surface of the object due to single-point force. A locking nut 404 is fitted onto the second end of the threaded rod 402. Tightening the nut axially fixes the threaded rod 402, preventing it from loosening due to vibration or external force. It should be understood that the fixing frame 401 can be a Q235 steel fixing frame or an aluminum alloy fixing frame, and can be adjusted according to the actual situation, without limitation here.
[0026] In practice, the inner wall of the fixing frame 401 is fitted against the object to be fixed, ensuring the frame axis is parallel or perpendicular to the object's axis. Initial positioning is achieved through the frame's shape. The threaded rod 402 is rotated, causing the pressure plate 403 to move axially along the threaded rod 402 until it lightly touches the object's surface. At this point, the threaded rod 402 is not yet under load, allowing for fine-tuning of the fixing frame 401 to ensure alignment. Then, the locking nut 404 is tightened, pushing the threaded rod 402 towards the inner wall, causing the pressure plate 403 to press against the object. Once the predetermined clamping force is reached, the locking nut 404 is tightened to fit against the outer wall of the fixing frame 401, using the friction of the locking nut 404's end face to lock the threaded rod 402 in place. For disassembly, the locking nut 404 is loosened in the reverse direction.
[0027] For example, such as Figure 3As shown, the fixing frame 401 in this embodiment includes a first fixing plate 4011 and two second fixing plates 4012. The two second fixing plates 4012 are arranged opposite to each other. The two ends of the first fixing plate 4011 are respectively connected to the ends of the second fixing plates 4012. The first fixing plate 4011 is perpendicular to the second fixing plates 4012. The inner sidewalls of the first fixing plate 4011 and the second fixing plate 4012 face the object to be fixed. The outer sidewall of the first fixing plate 4011 is connected to the end of the supporting spray structure 1. A through hole 405 is provided in the middle of one of the second fixing plates 4012, and the second end is away from the outer sidewall of the second fixing plate 4012.
[0028] In practice, the U-shaped opening of the fixing frame 401 is aligned with the object to be fixed, so that the inner walls of the first fixing plate 4011 and the two second fixing plates 4012 are in contact with the surface of the object to be fixed, forming an enclosing structure. At this time, the second fixing plate 4012 without the through hole 405 directly abuts against the object to be fixed, serving as the support side of the fixing frame 401, while the second fixing plate 4012 with the through hole 405 serves as the adjustment side. Next, the threaded rod 402 is rotated, causing the pressure plate 403 to gradually move towards the surface of the object to be fixed until the pressure plate 403 is tightly in contact with the object. With the two second fixing plates 4012 positioned opposite each other, the thrust of the threaded rod 402 is transmitted to one side of the object through the pressure plate 403, while the second fixing plate 4012 on the other side provides a reverse support force, forming a clamping effect on both sides, ensuring that the frame is stably fixed to the object. Finally, the locking nut 404 is tightened to lock the position of the threaded rod 402, completing the installation.
[0029] For example, the pressure plate in this embodiment is a flat pressure plate or a curved pressure plate. The flat pressure plate is parallel to and fits against the object's surface, allowing the axial force of the threaded rod to be evenly distributed across the object's surface, preventing localized stress concentration that could lead to deformation or damage. The curved pressure plate's curvature matches the object's surface (e.g., a semi-circular pressure plate corresponds to a circular pipe), achieving surface contact rather than point contact, significantly increasing the contact area, reducing unit pressure, and preventing the object from being crushed or developing indentations.
[0030] For example, in the embodiments of this application, the pressure plate has an anti-slip layer on the side facing the object to be fixed, so as to increase the friction between the plate and the object and prevent slippage after clamping.
[0031] In one alternative embodiment, adjacent dustproof nets in this application are rotatably connected by magnetic connectors. The magnetic connectors achieve quick docking of adjacent dustproof nets through magnetic attraction, eliminating the need for traditional fasteners such as screws and clips, significantly reducing installation time, and are particularly suitable for scenarios requiring frequent disassembly and assembly. During maintenance, only a slight external force is needed to overcome the magnetic force to open the dustproof net around the rotatable connection point. For example, when cleaning accumulated dust, the dustproof net to be cleaned can be directly rotated open.
[0032] For example, the dustproof structure 2 in this application embodiment also includes a plurality of sealing elements 202, each sealing element 202 being disposed at the rotating connection of adjacent dustproof nets 201 to prevent dust from falling into the rotating connection and improve the sealing performance of the dustproof device.
[0033] For example, the counterweight in this application embodiment is a metal counterweight. By increasing the inertial mass, the dustproof net can be kept vertically flat, preventing the net from swaying due to airflow or operational shaking, thus affecting the dustproof effect.
