Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology in mining, and more specifically, to a dust suppression device for mining. Background Technology

[0002] During mining operations, a large amount of dust is generated in the processes of ore extraction, crushing, and transportation. This dust not only seriously pollutes the working environment and affects the health of miners, easily causing occupational diseases such as pneumoconiosis, but also reduces visibility and increases the risk of safety accidents. At the same time, dust emissions also damage the surrounding ecological environment and exacerbate air pollution. Therefore, efficient dust suppression equipment is crucial for the safe production and green development of the mining industry.

[0003] However, current outdoor mining dust suppression methods mainly include physical dust suppression, mechanical dust removal, chemical dust suppression, and natural dust suppression aids. Among physical dust suppression methods, fixed spraying and misting systems have low equipment costs and simple maintenance, but their coverage area is fixed, water resources are wasted, and terrain adaptability is poor. Dust nets and windbreaks are suitable for static dust sources, but cannot cope with dynamic dust such as blasting and have coverage blind spots. Vehicle-mounted spray dust suppression equipment can follow moving dust sources, but it has high energy consumption and limited spray range. Mechanical dust removal methods, such as bag filters and electrostatic precipitators, have high dust removal efficiency but are only suitable for fixed scenarios. They have high equipment costs, complex maintenance, and are difficult to handle large areas or instantaneous strong dust in the open. Chemical dust suppression methods, such as dust suppressants, have a long-lasting effect, but the cost of the agents is high, they may pollute the environment, and it is difficult to cover evenly in complex terrain. Natural dust suppression aids, such as greening dust suppression, are eco-friendly, but they are slow to take effect, have low vegetation survival rates, and cannot cope with high-intensity dust. These methods generally have the problems of fixed or limited coverage area and insufficient flexibility, making it difficult to adapt to the dynamically changing dust sources at the mining site.

[0004] Therefore, a dust suppression device for mining is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a dust suppression device for mining, which uses multiple spray pipes to concentrate water spraying in conjunction with a large-capacity spray head to deal with local fires and play an emergency firefighting role. Opening multiple spray pipes can increase the spraying area and play a role in large-scale dust suppression.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A dust suppression device for mining includes a drone, the lower end of which is provided with a water storage component, the lower end of which is provided with a plurality of spray angle adjustment components, and the lower end of the plurality of spray angle adjustment components is provided with a drive component.

[0008] The water storage assembly includes a water tank fixedly connected to the lower end of the drone, a large-capacity water nozzle installed at the lower end of the water tank, multiple water delivery hoses connected to the middle of the water tank, and a sealing port connected to the upper end of the water tank.

[0010] Furthermore, the middle part of the spray pipe is connected to one end of the water delivery hose, and a return spring is fixedly connected inside the mounting housing, with one end of the return spring fixedly connected to the upper end of the spray pipe.

[0011] Furthermore, the drive assembly includes a fixed ring fixedly connected to the middle of the connecting bracket. A servo motor is fixedly connected to the upper end of the fixed ring, and a gear ring is rotatably connected to the lower end of the fixed ring. Multiple rotating shafts are rotatably connected to the lower end of the fixed ring. The upper end of one of the rotating shafts is fixedly connected to the output end of the servo motor, and gears are fixedly connected to the lower ends of the multiple rotating shafts. The multiple gears are meshed with the rotating shafts.

[0012] Furthermore, a limiting ring is fixedly connected to the upper end of each of the fixed brackets, and a plurality of T-shaped sliding blocks are slidably connected to the upper end of each of the limiting rings. A sliding plate is fixedly connected to the upper end of each of the T-shaped sliding blocks, and a trigger abutment rod is fixedly connected to the lower end of each of the sliding plates. One end of the trigger abutment rod is in low contact with the middle of the spray pipe, and a rack is fixedly connected to the upper end of each sliding plate.

This structure can not only flexibly change the spray direction and expand the coverage area, but also accurately control the spray angle according to different dust distribution conditions, which enhances the adaptability of the equipment to complex mining environments, meets diverse dust suppression needs, and has a stable and reliable structure and is easy to operate.

[0017] Multiple sprinkler pipes converge with large-capacity sprinkler heads to spray water in a concentrated manner, which can be used to deal with local fires and play an emergency firefighting role.

[0018] Opening multiple spray pipes can increase the spraying area and achieve a large-scale dust suppression effect.

Combined with multiple spray pipes for multi-angle and multi-directional spraying, it can significantly improve dust suppression efficiency, accurately and comprehensively suppress dust in different areas, and effectively improve the mining working environment.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0028] Reference Figures 1 to 5 As shown, a preferred embodiment of the present invention is a dust suppression device for mining, including a drone 1, a water storage component 2 at the lower end of the drone 1, a plurality of spray angle adjustment components 3 at the lower end of the water storage component 2, and a drive component 4 at the lower end of the plurality of spray angle adjustment components 3.

[0029] The water storage component 2 includes a water tank 201 fixedly connected to the lower end of the drone 1. A large-capacity water nozzle 202 is installed at the lower end of the water tank 201. Multiple water delivery hoses 203 are connected and installed in the middle of the water tank 201. A sealing port 204 is connected and installed at the upper end of the water tank 201.

[0030] This solution's drone 1 can quickly cover an area of ​​several square kilometers through aerial flight, accurately locating areas with high dust concentrations for targeted dust suppression. Traditional methods mostly rely on fixed equipment or manual operation, which has drawbacks such as water and chemical waste, high labor input, and high safety risks, such as workers needing to enter high-dust areas. Drone 1 can reduce resource consumption by dynamically adjusting the spray volume and flight path, while avoiding personnel exposure to dangerous environments. In addition, traditional methods have weak data management capabilities and find it difficult to optimize dust suppression plans in a timely manner, while drone 1 can simultaneously collect data such as dust concentration, achieving scientific and intelligent management.

[0031] The spray angle adjustment assembly 3 includes multiple connecting brackets 301 fixedly connected to the lower end of the water tank 201. The lower end of the connecting bracket 301 is fixedly connected to the mounting housing 302. The middle part of the mounting housing 302 is fixedly connected to the fixing bracket 303. The inside of the mounting housing 302 is fixedly connected to the U-shaped connecting frame 304. The lower end of the U-shaped connecting frame 304 is rotatably connected to the rotating block 305. The middle part of the rotating block 305 is fixedly connected to the spray water pipe 306.

[0032] The middle part of the spray pipe 306 is connected to one end of the water delivery hose 203. A return spring 307 is fixedly connected inside the housing 302. One end of the return spring 307 is fixedly connected to the upper end of the spray pipe 306.

[0033] This solution utilizes the flexibility and mobility of a drone (1) to quickly reach any area of ​​the mining site, overcoming the limitations of traditional fixed dust suppression equipment. Water is injected into the water tank (201) of the water storage assembly (2) through the sealing port (204), and then transported to the spray pipe (306) via the water delivery hose (203). Simultaneously, the large-capacity spray head (202) can also spray water. Together, these components provide a continuous and stable water source for dust suppression operations, ensuring the smooth progress of the dust suppression work.

[0034] The drive assembly 4 includes a fixed ring 401 fixedly connected to the middle of the connecting bracket 301. A servo motor 402 is fixedly connected to the upper end of the fixed ring 401. A gear ring 403 is rotatably connected to the lower end of the fixed ring 401. A plurality of rotating shafts 404 are rotatably connected to the lower end of the fixed ring 401. The upper end of one of the rotating shafts 404 is fixedly connected to the output end of the servo motor 402. A gear 405 is fixedly connected to the lower end of each of the plurality of rotating shafts 404. The plurality of gears 405 are meshed with the rotating shafts 404.

[0035] This solution utilizes the servo motor 402 in drive assembly 4, which, upon startup, drives the rotating shaft 404 and gear 405 to rotate. Gear 405 meshes with rack 410, causing sliding plate 408 to slide on limit ring 406. This triggers abutment rod 409, pushing spray pipe 306 to rotate around rotating block 305, thus achieving precise adjustment of the spray angle. The reset spring 307 ensures that spray pipe 306 quickly resets after adjustment, allowing for multiple angle adjustments based on actual needs to adapt to different dust distributions and enhance the equipment's adaptability to complex environments.

[0036] Multiple fixed brackets 303 are fixedly connected to the upper end of a limiting ring 406. Multiple T-shaped sliding blocks 407 are slidably connected to the upper end of the limiting ring 406. Sliding plates 408 are fixedly connected to the upper end of each of the multiple T-shaped sliding blocks 407. Triggering abutment rods 409 are fixedly connected to the lower end of each of the multiple sliding plates 408. One end of the triggering abutment rod 409 abuts against the middle of the spray pipe 306. A rack 410 is fixedly connected to the upper end of the sliding plate 408. Multiple racks 410 are respectively meshed with multiple gears 405.

[0037] This solution utilizes multiple spray pipes 306 to perform different functions in various scenarios. During dust suppression operations, multiple spray pipes 306 are opened to increase the spraying area and suppress dust from multiple angles and directions. When a local fire occurs at the mining site, multiple spray pipes 306 are concentrated and used in conjunction with large-capacity spray heads 202 to spray water from the water tank 201, achieving an emergency firefighting function. This gives the equipment both dust suppression and firefighting capabilities, enhancing its practicality.

[0038] The lower end of the mounting housing 302 has a strip-shaped hole that allows the spray pipe 306 to rotate.

[0039] The overall shape of the fixed bracket 303 is U-shaped.

[0040] Specific implementation process: First, the operator controls the drone 1 to take off and transport the equipment to the area of ​​the mining site that needs dust suppression. The drone 1 has flexible mobility and can quickly reach areas that are difficult to cover by traditional fixed dust suppression equipment. During the operation of the equipment, the water storage component 2 plays a role in water supply. The water tank 201 is filled with water in advance through the sealing port 204. During operation, the water delivery hose 203 connected in the middle of the water tank 201 delivers water to each spray water pipe 306. At the same time, the large-capacity water nozzle 202 at the lower end of the water tank 201 can also perform water spraying operations. The large-capacity water nozzle 202 works with the water delivery hose 203 to ensure a continuous and stable water supply. When it is necessary to adjust the spray angle, the drive component 4 starts to work. The servo motor 402 is installed on the upper end of the fixed ring 401. After the servo motor 402 starts, it drives the rotating shaft 404 fixedly connected to its output end to rotate. The gear 405 at the lower end of the rotating shaft 404 and other rotating shafts 404 The lower gears 405 mesh with each other, thereby driving multiple rotating shafts 404 to rotate together. When the gears 405 rotate, they mesh with the rack 410, causing the sliding plate 408 to slide along the limiting ring 406. The trigger abutment rod 409 at the lower end of the sliding plate 408 moves accordingly, pushing the spray pipe 306 to rotate around the rotating block 305 at the lower end of the U-shaped connecting frame 304, thereby adjusting the spray angle. When the adjustment stops, the reset spring 307 pulls the spray pipe 306 to quickly reset it, facilitating the next angle adjustment. During dust suppression operations, the state of the spray pipe 306 can be adjusted according to actual needs. If large-scale dust suppression is required, multiple spray pipes 306 can be opened to increase the spray area and suppress dust from multiple angles and directions. When a local fire occurs at the mining site, multiple spray pipes 306 can be gathered together and sprayed in conjunction with a large-capacity water head 202, using the water in the water tank 201 to extinguish the fire in an emergency.
