Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a tunnel top water sprinkler device for tunnel construction. Background Technology

[0002] During tunnel construction, blasting, excavation, and transportation activities generate a large amount of dust. This dust not only severely pollutes the construction environment but also damages the respiratory system of construction workers. Long-term exposure to such an environment can easily lead to occupational diseases such as pneumoconiosis. To effectively control dust pollution and ensure a safe and healthy construction environment, using water sprinkler systems to spray water on the tunnel ceiling to suppress dust has become a crucial measure.

[0003] However, in terms of water spraying effectiveness, the spraying angle of existing devices is often fixed and cannot be flexibly adjusted according to the actual shape of the tunnel, the construction progress, and the dust distribution. This results in some areas of the tunnel ceiling not being covered by water spraying, or uneven water spraying, which greatly reduces the dust suppression effect.

[0004] Regarding the durability and maintenance costs of the equipment, the water outlets of existing sprinkler systems are often clogged by impurities in the water, dust in the tunnel, and other particulate matter. Once the water outlets are clogged, the uniformity and coverage of the water spray will be severely affected, requiring frequent cleaning and maintenance. This not only increases maintenance costs but also leads to construction interruptions and delays in the project schedule.

[0005] Furthermore, existing devices have a relatively limited function, focusing solely on water spraying for dust suppression while neglecting the treatment of dust after suppression. If the dust is not properly handled, it can easily be stirred up again during subsequent construction activities, such as vehicle movement and machinery operation, causing renewed dust pollution and hindering the smooth progress of subsequent construction. Therefore, those skilled in the art have provided a tunnel roof water spraying device for tunnel construction to solve the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tunnel top water spraying device for tunnel construction. To achieve the above objective, this utility model provides the following technical solution: It includes a base, with fixed plates installed at the middle of both sides of the top of the base. The fixed plates are mirror-image opposite each other. Adjustable rods are rotatably connected to the middle of the middle of the two side walls of the fixed plates near their upper ends. A spray cannon is installed between the adjustable rods. A first drive motor is connected to the input end of any one of the adjustable rods. The housing of the first drive motor is installed at the middle of the middle of the side wall of the corresponding fixed plate near its upper end. A high-pressure plate is installed at the output end of the spray cannon. A sealing plate is welded to the middle of the inner side wall of the high-pressure plate. The output end of the high-pressure plate has several water outlet holes arranged in a polar array. A fan is connected to the mounting end of the sealing plate. The radius of the fan is larger than the radius of the high-pressure plate. When the fan connected to the sealing plate rotates, its larger radius disperses the water mist, making it more evenly sprayed on the tunnel top. Furthermore, the fan generates a strong airflow. Because the fan radius is larger than the high-pressure plate radius, the airflow can cover the water outlet area on the high-pressure plate. When impurities or small particles approach the water outlet, the airflow will generate a certain scouring force, blowing these impurities or small particles away from the area around the water outlet, making it difficult for them to accumulate at the water outlet, thereby reducing the possibility of blockage and ensuring stable watering operations.

[0007] Preferably, the output end of the rotary driver acts on the base to rotate, thereby adjusting the water spraying direction of the equipment. The water tank is used to store the liquid required for spraying and is connected to the water pipe through a liquid pump.

[0008] Preferably, a first extension block is installed on the front side wall of the water tank, an installation plate is installed at the bottom middle position of the first extension block, a second drive motor is installed at the top middle position of the installation plate near the front side, and a steering wheel is rotatably connected to the bottom middle position of the installation plate near the front side, and the output end of the second drive motor is connected to the input end of the steering wheel.

[0009] Preferably, the two side walls of the compaction plate are slidably connected to the inner side walls of the corresponding limiting recesses. The limiting recess at the bottom of the drive block on the rear side wall of the water tank cooperates with the compaction plate connected to the connecting rod. During the movement of the device, the compaction plate will compact the dust after dust reduction to prevent the dust from being stirred up again.

[0010] Preferably, a connector is installed at the middle of both sides of the water tank, and an installation block is installed on each side of the connector. A driver is installed at the middle of the front and rear side walls of the installation block. The output end of the driver is connected to a driven sprocket. A track is fitted on the outer side wall of the driven sprocket. The driver acts on the driven sprocket to rotate synchronously, causing the two tracks to move, thereby enabling the equipment to move inside the tunnel.

[0011] Preferably, the water tank is connected to a water pipe, the output end of which passes through the top middle of the base and is connected to the input end of the spray cannon. A limiting plate is fitted on the top middle of the base and on the outer wall of the spray cannon.

[0012] Preferably, the water tank has a water inlet at its input end, which is used to replenish the required liquid.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this invention, the fan connected to the sealing disc rotates, and the fan radius is larger than the high-pressure disc radius. On the one hand, this disperses the water mist, making it more evenly distributed on the tunnel ceiling. On the other hand, the fan generates a strong airflow when it rotates. Because the fan radius is larger than the high-pressure disc radius, the airflow can cover the water outlet area on the high-pressure disc. When impurities or small particles approach the water outlet, the airflow generates a certain scouring force, blowing these impurities or small particles away from the area around the water outlet, making it difficult for them to accumulate at the water outlet, thereby reducing the possibility of blockage and ensuring stable water spraying operations.

[0015] 2. In this utility model, the driving block on the rear side wall of the water tank is connected to the compaction plate via a connecting rod. During the movement of the device, the compaction plate compacts the dust after dust suppression, preventing the dust from being stirred up again, thus improving the dust suppression process, keeping the environment inside the tunnel clean, and facilitating subsequent construction.

[0016] 3. In this utility model, the first drive motor on the fixed plate drives the adjusting rod, thereby driving the spray cannon to adjust the angle and achieve multi-angle water spraying. Moreover, the fan works in conjunction with the high-pressure plate, and the fan blows the water mist sprayed from the water outlet of the high-pressure plate to make the water mist more evenly sprayed on the top of the tunnel, resulting in better dust suppression and avoiding uneven dust suppression in some areas.

[0023] Reference Figure 1 — Figure 4This invention relates to a tunnel roof watering device for tunnel construction. The purpose of this invention is to address the shortcomings of existing technologies by providing a tunnel roof watering device for tunnel construction. To achieve the above objective, this invention provides the following technical solution: It includes a base 1, with fixed plates 2 installed at the middle positions of both sides of the top of the base 1. The fixed plates 2 are mirror-image opposite each other. Adjustable rotating rods 5 are rotatably connected to the middle of the two side walls of the fixed plates 2 near their upper ends. A spray cannon 6 is installed between the adjustable rotating rods 5. A first drive motor 4 is connected to the input end of any one of the adjustable rotating rods 5. The housing of the drive motor 4 is mounted on the middle of one side wall of the corresponding fixed plate 2, near the upper end. A high-pressure disc 7 is mounted on the output end of the spray cannon 6. A sealing disc 9 is welded to the middle of the inner side wall of the high-pressure disc 7. The output end of the high-pressure disc 7 has several water outlet holes 8 arranged in a polar array. A fan 10 is connected to the mounting end of the sealing disc 9. The radius of the fan 10 is larger than the radius of the high-pressure disc 7. When the fan 10 connected to the sealing disc 9 rotates, its larger radius disperses the water mist, making it more evenly distributed on the tunnel ceiling. Furthermore, the rotation of the fan 10 generates a strong airflow. Because the radius of the fan 10 is larger than that of the high-pressure disc 7, the airflow can cover the water outlet area on the high-pressure disc 7. When impurities or small particles approach the water outlet holes 8, the airflow generates a certain scouring force, blowing these impurities or small particles away from the area around the water outlet holes 8, making it difficult for them to accumulate there, thus reducing the possibility of blockage and ensuring stable water spraying operations.

[0024] A rotary driver 19 is installed at the bottom center of the base 1. The output end of the rotary driver 19 is connected to the bottom of the base 1. A water tank 20 is installed at the bottom center of the rotary driver 19. The output end of the rotary driver 19 acts on the base 1 to rotate, thereby adjusting the water spraying direction of the equipment. The water tank 20 is used to store the liquid required for water spraying and is connected to the water pipe 27 through a liquid pump.

[0025] A drive block 21 is installed on the rear side wall of the water tank 20. Limiting recesses 23 are installed on the bottom two sides of the drive block 21 near the rear side. Several connecting rods 24 arranged in an array are installed on the output end of the drive block 21. A compaction plate 22 is connected to the bottom of the connecting rod 24. The two side walls of the compaction plate 22 are slidably connected to the inner side walls of the corresponding limiting recesses 23. The limiting recesses 23 at the bottom of the drive block 21 on the rear side wall of the water tank 20 cooperate with the compaction plate 22 connected to the connecting rods 24. During the movement of the device, the compaction plate 22 will compact the dust after dust suppression to prevent the dust from being stirred up again.

[0026] Connectors 25 are installed in the middle of both sides of the water tank 20. Mounting blocks 18 are installed on both sides of the connector 25. Drivers 15 are installed in the middle of the front and rear sides of the mounting blocks 18. The output end of each driver 15 is connected to a driven sprocket 17. Tracks 16 are fitted on the outer side of each driven sprocket 17. The driven sprocket 17 is rotated synchronously by the driver 15, so that the two tracks 16 move, thereby moving the equipment in the tunnel.

[0027] A first extension block 11 is installed on the front side wall of the water tank 20. An installation plate 13 is installed at the bottom center of the first extension block 11. A second drive motor 12 is installed at the top center of the installation plate 13 near the front side. A steering wheel 14 is rotatably connected to the bottom center of the installation plate 13 near the front side. The output end of the second drive motor 12 is connected to the input end of the steering wheel 14. A water pipe 27 is connected to the output of the water tank 20. The output end of the water pipe 27 passes through the top center of the base 1 and is connected to the input end of the spray cannon 6. A limiting plate 3 is fitted on the top center of the base 1 and on the outer side wall of the spray cannon 6. A water injection hole 26 is opened at the input end of the water tank 20. The water injection hole 26 is used to replenish the required liquid.

[0028] Working principle: First, the rotary drive 19 is installed at the bottom center of the base 1, with its output end connected to the bottom of the base 1. A water tank 20 is installed at the center of the bottom. The second drive motor 12 on the bottom mounting plate 13 of the first extension block 11 on the front side wall of the water tank 20 drives the steering wheel 14 to rotate, realizing the steering of the device. The limiting recess 23 at the bottom of the drive block 21 on the rear side wall of the water tank 20 cooperates with the compaction plate 22 connected to the connecting rod 24. During the movement of the device, the compaction plate 22 will compact the dust after dust suppression, preventing the dust from being stirred up again. The drive 15 on the mounting block 18 on the connecting parts 25 on both sides of the water tank 20 drives the driven sprocket 17, which drives the track 16 to rotate, realizing the overall movement of the device in the tunnel.

[0029] Water tank 20 delivers water to spray cannon 6 via water pipe 27. Spray cannon 6 is mounted between adjusting rods 5 driven by a first drive motor 4 on fixed plate 2. The first drive motor 4 can rotate the adjusting rods 5 to adjust the angle of spray cannon 6 to meet the watering needs of different locations. After entering spray cannon 6, water reaches high-pressure plate 7. High-pressure plate 7 has a sealing plate 9 on its inner side and several water outlet holes 8 at its output end. Water is sprayed out from the water outlet holes 8 to form a water mist. At the same time, fan 10 connected to sealing plate 9 rotates. The radius of fan 10 is larger than that of high-pressure plate 7. On the one hand, it can disperse the water mist, making the water mist more evenly sprayed on the tunnel top. On the other hand, the rotation of fan 10 generates a strong airflow. Because the radius of fan 10 is larger than that of high-pressure plate 7, the airflow can cover the water outlet area on high-pressure plate 7. When impurities or small particles approach the water outlet holes 8, the airflow will generate a certain scouring force, blowing these impurities or small particles away from the area around the water outlet holes 8, making it difficult for them to accumulate at the water outlet holes 8, thereby reducing the possibility of blockage and ensuring stable watering operation.

[0030] The water tank 20 has a water inlet 26 at the inlet end to replenish the liquid required for the operation and ensure that the watering operation can continue.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
