Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, and in particular to a water-saving coal mine dust suppression spray device. Background Technology

[0002] Coal mines, as specific areas where humans extract coal resources, are mainly divided into underground coal mines and open-pit coal mines based on the distance between the coal seam and the surface. When the coal seam is buried deep underground and far from the surface, people usually use the method of digging tunnels underground to extract coal. These types of coal mines are called underground coal mines.

[0003] In recent years, with the continuous improvement of the level of mechanization in coal mine production, a serious problem has gradually emerged in the process of coal mine civil construction: the dust content in the air has risen sharply, which not only poses a serious threat to the safe production of coal mines, but also greatly endangers the health of on-site workers.

[0004] To address this issue, existing environmental protection equipment mostly employs spraying to reduce dust and improve the working environment. However, these spraying devices have revealed significant shortcomings in actual use:

[0005] The spray angle is difficult to adjust. Specifically, most existing spray devices are fixed structures without angle adjustment functions or have complex structures that require the use of special tools. This not only increases the operational burden on workers, but also makes it impossible to accurately target dust distribution areas, thus seriously affecting dust suppression efficiency. Furthermore, the spray system of existing spray devices is difficult to control precisely, resulting in uneven water mist distribution. Some areas have excessively concentrated water mist, causing water waste, while other areas cannot be effectively covered, resulting in poor dust suppression effect.

[0006] In response to this technical problem, this application proposes a water-saving coal mine dust suppression spray device. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-saving coal mine dust suppression spray device. This device allows for adjustments to the horizontal and vertical angles according to the distribution of coal mine dust, effectively addressing dust conditions in different scenarios. Simultaneously, the combination of wind-assisted spraying and a spray system ensures that a small amount of water mist is evenly distributed by the wind, and further enhances the binding efficiency with dust through secondary atomization and complex motion, reducing the amount of water sprayed to meet dust suppression standards and improving dust suppression efficiency.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A water-saving dust suppression spray device for coal mines includes a base, a bottom plate rotatably connected to the top of the base, a motor fixedly connected to the bottom of the bottom plate, support rods fixedly connected to the left and right ends of the top of the bottom plate, a shaft connecting the adjacent side of the support rod to a mounting plate, and a telescopic assembly connecting the right end of the shaft to a positioning block. The positioning block engages with the support rod through a positioning groove. The top of the mounting plate is connected to a fixed seat via a fixing bolt. Multiple nozzles are fixedly connected to the front of the fixed seat. Multiple mounting grooves are formed on the front of the support rods, and these mounting grooves are connected to the mounting block via a fixing assembly. The mounting block is fixedly connected to the rear of the housing, and a fan is rotatably connected to the inner side of the housing.

[0010] Furthermore, a water pipe is fixedly connected to the middle of the rear side of the fixing base, and the right end of the water pipe is connected to the bottom of the outer side of the water tank. An observation window is provided on the right side of the outer wall of the water tank.

[0011] Furthermore, the shaft is rotatably connected to the support rod.

[0012] Furthermore, the telescopic assembly includes a telescopic hole, which is located on the right side of the right end of the shaft. A tension spring is fixedly connected to the left side of the inner wall of the telescopic hole. The telescopic hole is connected to a sleeve through the tension spring, and the sleeve is fixedly connected to the left side of the positioning block.

[0013] Furthermore, the two ends of the tension spring are respectively fixedly connected to the side of the telescopic hole and the sleeve, and the inner wall of the sleeve is slidably connected to the outer wall of the right end of the shaft.

[0014] Furthermore, the positioning groove is formed at the top of the outer wall of the right-side support rod.

[0015] Furthermore, the fixing component includes fixing holes, which are opened on the left and right sides of the outer wall of the mounting plate. Fixing bolts are threadedly connected inside the fixing holes, and fixing bolts are threadedly connected to the mounting block.

[0016] Furthermore, rollers are fixedly connected to the four corners of the bottom of the seat, and a push rod is fixedly connected to the rear end of the top of the seat.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, the angle is adjustable, and the adaptability is greatly improved. When using the device, the horizontal and vertical angles can be adjusted according to the complex dust distribution in different areas of the coal mine, which greatly improves the applicability of the device in various complex coal mine scenarios and can effectively cope with different dust generation conditions.

[0019] 2. In this utility model, wind-assisted spraying and a spray system are combined. A smaller amount of water mist can be sprayed more evenly to cover the entire mining face under the action of wind, avoiding repeated or excessive water spraying. At the same time, the wind generated by the fan can atomize the water mist a second time, and the fan makes the movement of the water mist in the air more complex, increasing the probability of collision and adsorption time between the water mist and dust. This allows the water mist to combine more fully with the dust, improves dust suppression efficiency, and thus reduces the amount of water sprayed to meet the dust suppression standards.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3This utility model provides an embodiment of a water-saving coal mine dust suppression spraying device, including a base 1, a base plate 2 rotatably connected to the top of the base 1, and a motor fixedly connected to the bottom of the base plate 2. In the complex and diverse working environment of coal mines, the dust distribution varies greatly in different areas, and the layout of the tunnel spaces also differs. The motor drives the base plate 2 to rotate, allowing for convenient and precise adjustment of the angle of the base plate 2 according to the actual dust distribution and tunnel space layout. This makes the spraying angle of the nozzles 8 installed on the subsequent structure more flexible, and the nozzles 8 can point in different directions according to actual needs to achieve a more precise dust suppression spraying effect. This greatly improves the applicability of the device in different coal mine scenarios and can effectively cope with various complex dust generation conditions. Support rods 3 are fixedly connected to both ends of the device. The side of the support rods 3 closest to each other is connected to the mounting plate 5 via a shaft 4. The shaft 4 not only connects the mounting plate 5 to the support rods 3, but more importantly, it provides the mounting plate 5 with a degree of freedom of rotation. In practical applications, dust generation points at different locations in coal mines have different heights, angles, and distribution characteristics. The shaft 4 allows the mounting plate 5 to rotate flexibly within a certain range. Operators can further fine-tune the angle of the mounting plate 5 according to the specific conditions of the actual dust source, allowing the spray direction of the nozzle 8 to be more accurately aimed at the dust generation point, thereby significantly improving dust suppression efficiency and ensuring that the device can achieve the best dust suppression effect in different dust environments. The right-end shaft 4 is connected to the positioning block via a telescopic component 14. The telescopic assembly 14, connected to the mounting plate 5, is a key component for fine-tuning the angle of the mounting plate 5. The positioning block 15 engages with the support rod 3 via the positioning groove 16. When the mounting plate 5 is adjusted to the appropriate angle via the telescopic assembly 14, the positioning block 15 will engage with the positioning groove 16. In the harsh working environment of underground coal mines, the device is subject to various vibrations and external forces during operation. The tight engagement between the positioning block 15 and the positioning groove 16 effectively prevents the angle of the mounting plate 5 from shifting under these adverse factors. The top of the mounting plate 5 is connected to the fixing seat 7 via a fixing bolt 6. Multiple nozzles 8 are fixedly connected to the front of the fixing seat 7. During dust control operations in coal mines, the nozzles 8 may experience blockages and wear due to prolonged exposure to dust, requiring regular maintenance. Regular maintenance or replacement is required, and the detachable design improves the maintainability of the device, reduces maintenance costs and time, and ensures that the device can always maintain a good working condition. Multiple mounting slots 9 are provided on the front side of the support rod 3. These mounting slots 9 are connected to the mounting block 10 via a fixing component 13. The mounting block 10 is fixedly connected to the rear side of the housing 11. A fan 12 is rotatably connected to the inside of the housing 11. When the fan 12 operates, it generates a strong wind. This wind force can disperse the water mist sprayed from the nozzle 8 to a greater distance and wider area. In the coal mine space, the spray range of the nozzle 8 itself is limited. The wind force of the fan 12 can cover corners and areas that are originally difficult to reach, greatly increasing the contact area and opportunity between the water mist and dust.This improves dust suppression. On the other hand, the airflow generated by fan 12 accelerates air circulation within the coal mine, allowing dust-laden air to contact and settle more quickly with the water mist. In the relatively enclosed underground space of a coal mine, poor air circulation leads to dust accumulation. The operation of fan 12 improves air circulation, making it easier for dust to be captured by the water mist and settle to the ground, effectively improving the air quality of the coal mine working environment. Furthermore, by utilizing the water mist more effectively, the binding efficiency between the water mist and dust is improved. While achieving the same dust suppression effect, water consumption can be reduced, thus achieving water conservation.

[0027] Reference Figures 1-3 A water pipe 21 is fixedly connected to the middle of the rear side of the fixed base 7. The right end of the water pipe 21 is connected to the bottom of the outer side of the water tank 17. An observation window 18 is provided on the right side of the outer wall of the water tank 17. The observation window 18 on the right side of the outer wall of the water tank 17 provides the operator with a direct way to understand the water level in the water tank 17. In the complex working environment of the coal mine, the operator can quickly check the water level through the observation window 18 at any time and make timely water replenishment operations to avoid the sprinkler device from failing to work properly due to water shortage in the water tank 17, thus ensuring the continuity and stability of the device operation. The shaft 4 and the support The rod 3 is rotatably connected. The telescopic assembly 14 includes a telescopic hole 1401, which is located on the right side of the right end shaft 4. A tension spring 1402 is fixedly connected to the left side of the inner wall of the telescopic hole 1401. The telescopic hole 1401 is connected to the sleeve 1403 through the tension spring 1402. The sleeve 1403 is fixedly connected to the left side of the positioning block 15. The two ends of the tension spring 1402 are respectively fixedly connected to the sides of the telescopic hole 1401 and the sleeve 1403. The inner wall of the sleeve 1403 is slidably connected to the outer wall of the right end shaft 4. When it is necessary to adjust the angle of the mounting plate 5... The operator applies external force to the positioning block 15. Under the action of the external force, the tension spring 1402 deforms, either compressing or extending, thereby driving the sleeve 1403 to slide within the telescopic hole 1401, changing the relative position of the positioning block 15 and the shaft 4, and realizing fine adjustment of the angle of the mounting plate 5. This design can accurately adjust the angle of the mounting plate 5 according to the complex and ever-changing dust distribution at the coal mine site, so that the nozzle 8 is always at the optimal spray angle, greatly improving the flexibility and dust suppression effect of the device. The positioning groove 16 is opened at the top of the outer wall of the right support rod 3 for fixing. Component 13 includes fixing holes 1301, which are opened on the left and right sides of the outer wall of the mounting plate 5. Fixing bolts 1302 are threaded inside the fixing holes 1301 and are threaded to the mounting block 10. Rollers 19 are fixedly connected to the four corners of the bottom of the seat 1. Push rods 20 are fixedly connected to the rear end of the top of the seat 1. The rollers 19 and push rods 20 can flexibly adjust the position of the device according to actual operation needs, reducing the physical exertion of operators when moving the device and further enhancing the practicality and convenience of the device in the coal mine operation environment.

[0028] Working principle: During operation, the bottom rollers 19 of the seat 1 cooperate with the top push rod 20, facilitating the operator's flexible movement of the device to the work area. The bottom plate 2 of the seat 1 is driven to rotate by the bottom motor, precisely adjusting its angle according to the dust distribution and tunnel layout, thereby flexibly adjusting the spray angle of the nozzles 8 installed on the subsequent structure. At the same time, the shaft 4 allows the mounting plate 5 to rotate, enabling the operator to fine-tune its angle according to the dust source, making the spray from the nozzles 8 more precise. The telescopic component 14 achieves fine adjustment of the angle of the mounting plate 5 through the extension and retraction of the tension spring 1402 and the sleeve 1403. The positioning block 15 and the positioning groove 16 are engaged. To prevent angular deviation, the mounting plate 5 has a fixed base 7 that connects to multiple nozzles 8. When a nozzle 8 malfunctions after long-term use, its detachable design with the fixed base 7 facilitates maintenance and replacement. The water tank 17 supplies water to the nozzles 8 via the water pipe 21. The observation window 18 allows operators to check the water level and replenish water in time. The fan 12 inside the housing 11 blows away the water mist sprayed from the nozzles 8, expanding the coverage area, accelerating air circulation, improving dust suppression, and saving water. The connection between the mounting groove 9, the fixing component 13, and the mounting block 10 allows for flexible adjustment of the installation position of the housing 11 and the fan 12, ensuring efficient operation of the device in different coal mine scenarios.
