Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of spray device technology, specifically to a dust removal spray device for safety engineering. Background Technology
[0002] Dust suppression spraying devices for emergency management in safety engineering are a type of equipment used in emergency management. Their main purpose is to reduce or eliminate suspended dust in the air, especially in the event of dangerous events such as fires or explosions, to protect the safety of workers and prevent secondary disasters caused by dust. Dust suppression spraying devices can effectively capture dust particles in the air by spraying water mist or fire extinguishing foam through spraying devices, causing the dust particles to settle, reducing dust concentration, reducing dust accumulation, and preventing the occurrence of explosions or fires.
[0003] Chinese Patent Publication No. CN215276414U discloses a dust suppression spraying device for safety engineering, relating to the field of spraying device technology. It addresses the inconvenience of existing dust suppression spraying devices, which typically require manual rotation of a trolley for multi-directional spraying. The proposed device includes an installation mechanism; the installation mechanism is the main body of the dust suppression spraying device, with a rotating mechanism mounted on its top; a spraying mechanism is mounted on top of the rotating mechanism; an adjustment mechanism and storage component are mounted inside a placement component on the top left side of the rotating mechanism; a rotating groove is formed on top of the placement component; the rotating component is installed inside the rotating groove; and side components are installed on both sides of the top of the rotating component. By rotating the spraying component, the spraying component drives the side components on both sides, which in turn drives the rotating component, causing the annular structure at the bottom of the rotating component to rotate inside the rotating groove, thus enabling the spraying component to rotate in multiple directions.
[0004] The aforementioned patent mentions that when adjusting the height of the spray nozzles, the dust removal spray device can only change the spray angle of the nozzles, which has a relatively limited range. In scenarios with larger working surfaces or requiring spraying over longer distances, the spraying effect is poor when covering high or distant areas, and it is difficult to widely change the coverage range of the spray. For scenarios requiring large-scale, high-altitude, or long-distance spraying, the effect of rotating to adjust the height of the spray nozzles is not ideal. Therefore, we propose a dust removal spray device for safety engineering. Utility Model Content

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0025] See Figures 1-3 and Figures 5-6As shown, a dust suppression spraying device for safety engineering includes a spraying device body 1 and a spraying cylinder 101. The spraying cylinder 101 is disposed on the spraying device body 1. It also includes a circular plate 2, a support 201, a first support plate 202, a second support plate 203, and a lifting mechanism. The circular plate 2 is rotatably disposed on the spraying device body 1. The support 201 is rotatably disposed on the circular plate 2. The inner side of the first support plate 202 is connected to the outer side of the spraying cylinder 101. The top end of the second support plate 203 is connected to the outer side of the spraying cylinder 101. The lifting mechanism is disposed between the spraying cylinder 101 and the support 201, and is used to drive the spraying cylinder 101 to move vertically. The lifting mechanism includes a first transmission mechanism, a second transmission mechanism, and a motor 20. 4; A first transmission mechanism is disposed within the first support plate 202, and the first transmission mechanism is used to drive the first support plate 202 to move the spray cylinder 101 vertically; a second transmission mechanism is disposed within the second support plate 203, and the second transmission mechanism is used to drive the second support plate 203 to move the spray cylinder 101 vertically; a motor 204 is disposed on the bracket 201; the first transmission mechanism includes a first screw 205, a first slide rod 206, and a first sliding groove 207; the first screw 205 is threadedly connected to the first support plate 202; one end of the first slide rod 206 is slidably inserted into the first support plate 202, and the lower end of the first slide rod 206 is connected to the bracket 201; the first sliding groove 207 is opened on the side of the first support plate 202 near the first slide rod 206. The first slide groove 207 is used to cooperate with the first slide rod 206 for vertical movement; the second transmission mechanism includes a second screw 208, a second slide rod 209, and a second slide groove 210; the second screw 208 is threadedly connected to the second support plate 203; one end of the second slide rod 209 is slidably inserted into the second support plate 203, and the lower end of the second slide rod 209 is connected to the bracket 201; the second slide groove 210 is opened on the side of the second support plate 203 near the second slide rod 209, and is used to cooperate with the second slide rod 209 for vertical movement; the lower ends of the first screw 205 and the second screw 208 are provided with a synchronization assembly, which includes a first synchronization pulley 211, a first synchronization belt 212, a guide pulley 213, and a second synchronization pulley 214. 14 and a second synchronous belt 215; a first synchronous pulley 211 is rotatably disposed within a bracket 201; a first synchronous belt 212 meshes with the first synchronous pulley 211, the first synchronous pulley 211 in the middle of the first synchronous belt 212 is connected to the output end of the motor 204, and the first synchronous pulleys 211 at both ends of the first synchronous belt 212 are connected to the first screw 205; a guide wheel 213 is disposed outside the first synchronous belt 212, and the guide wheel 213 is rotatably disposed within the bracket 201, the guide wheel 213 is used to prevent the first synchronous belt 212 from disengaging from the first synchronous pulley 211; a second synchronous pulley 214 is disposed below the first synchronous pulley 211, and the second synchronous pulley 214 is rotatably disposed within the bracket 201;The second synchronous belt 215 meshes with the second synchronous pulley 214. The second synchronous pulley 214 at one end of the second synchronous belt 215 is connected to the first synchronous pulley 211, and the second synchronous pulley 214 at the other end of the second synchronous belt is connected to the second screw 208.
[0026] Specifically, the first slide bar 206 is adapted to the first slide groove 207, and the second slide bar 209 is adapted to the second slide groove 210.
[0027] When the dust removal spraying device is in operation, the motor 204 is started. The output end of the motor 204 drives the first synchronous pulley 211 in the middle of the first synchronous belt 212 to rotate. At the same time, the first synchronous pulley 211 in the middle of the first synchronous belt 212 drives the second synchronous pulley 214 at one end of the second synchronous belt 215 to rotate. When the first synchronous pulley 211 in the middle of the first synchronous belt 212 rotates, since the first synchronous pulley 211 meshes with the first synchronous belt 212, the first synchronous pulleys 211 at both ends of the first synchronous belt 212 will synchronously drive the first screw 205 to rotate. Since the first support plate 202 and the first screw 205 are connected by threads, the first support plate 202 can move upward along the outer surface of the screw. During this process, the first slide rod 206 slides along the inner side of the first sliding groove 207. Given that the first slide rod 206 and the first sliding groove 207 are mutually adapted, the first slide rod 206 can stably cooperate with the first screw 205 to support the spray cylinder 101.
[0028] When the second synchronous pulley 214 at one end of the second synchronous belt 215 rotates, based on the meshing relationship between the second synchronous pulley 214 and the second synchronous belt 215, the second synchronous pulley 214 at the other end of the second synchronous belt 215 drives the second screw 208 to rotate. Since the second screw 208 is threadedly connected to the second support plate 203, the second support plate 203 supports the spray cylinder 101 to move upwards, while the second slide rod 209 slides along the second slide groove 210. Because the second slide rod 209 and the second slide groove 210 are mutually compatible, the second slide rod 209 can work in conjunction with the second screw 208 to provide stable support for the spray cylinder 101. At this time, the first support plate 202 and the second support plate 203 simultaneously and stably support the upward movement of the spray cylinder 101. The height of the upward movement of the spray cylinder 101 can be adjusted according to the required dust suppression range, allowing the mist droplets sprayed by the spray cylinder 101 to diffuse more widely in the air, effectively expanding the coverage area of the dust suppression spray device for emergency management in safety engineering, thereby improving dust suppression efficiency.
[0029] See Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the circular plate 2 is equipped with a transmission mechanism, which includes a gear 216, a toothed plate 217, a cylinder 218, a slider 219, and a guide groove 220. The gear 216 is fixedly installed on the outside of the circular plate 2. The toothed plate 217 meshes with the gear 216. The working end of the cylinder 218 is connected to one end of the toothed plate 217. The upper side of the slider 219 is connected to the lower side of the toothed plate 217. The guide groove 220 is opened on the side of the spray device body 1 near the slider 219, and the guide groove 220 is used to cooperate with the slider 219 to move linearly. The second support plate 203 is provided with a guiding mechanism, which is used to drive one end of the spray cylinder 101 to swing up and down. The guiding mechanism includes a spherical support block 221 and a guide plate 222. The spherical support block 221 is connected to the bottom of the second support plate 203. The guide plate 222 is located on the lower side of the spherical support block 221 and is connected to the main body 1 of the spraying device. An elastic reset member 223 is provided between the circular plate 2 and the bracket 201. The two ends of the elastic reset member 223 are respectively connected to one side of the circular plate 2 and the bracket 201.
[0030] Specifically, the slider 219 is adapted to the guide groove 220, the elastic reset component 223 uses a spring as the actuating element, and the spherical support block 221 is adapted to the curved surface of the guide plate 222.
[0031] After the lifting mechanism completes the adjustment of the height of the spray cylinder 101, the cylinder 218 is activated. The output end of the cylinder 218 drives the toothed plate 217 to move. Since the slider 219 is adapted to the guide groove 220, the toothed plate 217 can move stably. During the movement, the toothed plate 217 meshes with the gear 216, causing the gear 216 to rotate, which in turn drives the circular plate 2 to rotate. When the circular plate 2 rotates, it drives the spray cylinder 101 to rotate together through the bracket 201. During this period, the first support plate 202 drives the spherical support block 221 to slide along the curved surface of the guide plate 222. When the spherical support block 221 moves to the high point of the curved surface of the guide plate 222, the spherical support block 221 pushes one end of the bracket 201 upward, causing the bracket 201 to rotate upward on the upper side of the circular plate 2. At the same time, the bracket 201 stretches the elastic reset member 223. At this time, the bracket 201 drives the spray nozzle of the spray cylinder 101 to rotate upward. When the spherical support block 221 moves from the high point to the low point of the curved surface of the guide plate 222, the bracket 201 stops stretching the elastic reset member 223. At this time, the elastic reset member 223 contracts and pulls the bracket 201, causing the bracket 201 to drive the spray nozzle of the spray cylinder 101 to rotate downward.
[0032] Thus, during the rotation of the spray cylinder 101, the spray nozzles of the spray cylinder 101 can swing up and down, effectively expanding the vertical coverage of the spray cylinder 101 and ensuring that the spray can cover more areas at different heights. For irregular or undulating sites, the up-and-down swing of the spray cylinder 101 helps to better adjust the spray direction, eliminate spray dead zones, and make the spray coverage of the dust suppression spray device for emergency management of safety engineering more comprehensive.
[0033] Working principle: When the dust suppression spray device for emergency management of safety engineering is in operation, the overall height of the spray cylinder 101 can be adjusted through the lifting mechanism. This allows the spray cylinder 101 to be adjusted upward according to the required dust suppression range, enabling the mist droplets sprayed by the spray cylinder 101 to spread more widely in the air, thus improving dust suppression efficiency. After the height of the spray cylinder 101 is adjusted, the transmission mechanism allows the spray cylinder 101 to rotate and swing up and down simultaneously, effectively expanding the vertical coverage of the spray cylinder 101, eliminating spray dead zones, and making the spray coverage of the dust suppression spray device for emergency management of safety engineering more comprehensive.
[0034] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
