Description

Technical Field

[0001] This utility model belongs to the field of dust suppression technology in underground coal mine roadways, specifically an automatic spray dust suppression device for underground coal mine roadways. Background Technology

[0002] Unloading in the main shaft is a crucial step in coal hoisting in a mine. Each unloading operation generates coal dust. Since the main shaft is also an air intake shaft, the generated coal dust not only harms the unloading process but also enters the mine with the incoming air, posing a similar hazard to underground loading. Therefore, dust suppression during unloading becomes an important part of the mine's dust control efforts.

[0003] Meanwhile, application number CN202120186903.9, entitled "An Automatic Spray Dust Suppression Device for Coal Mines," describes a similar device. This device includes a base plate, rollers, a handrail, and a water tank. Multiple rollers are symmetrically installed at the bottom of the base plate, and the water tank is supported at the top. A handrail is located on one side of the water tank, and supports are symmetrically installed on the other side. A rotating mechanism is supported by both supports, and multiple atomizing nozzles are evenly installed on the rotating mechanism. An adjustment component is installed on the rotating mechanism, connecting and cooperating with each atomizing nozzle. A water pump is installed at the top of the water tank. This invention not only allows the atomizing nozzles to swing left and right but also to adjust their vertical tilt angle, thereby increasing the spray range and dust suppression efficiency. Simultaneously, it makes the water tank installation more stable, avoiding excessive stress on internal parts and extending the overall lifespan of the device. Furthermore, the improved stability also enhances the device's adaptability to different locations.

[0004] In the above-mentioned technical solution, during use, since the atomizing nozzle is directly exposed to the complex dust environment underground, as the usage time increases, a large amount of coal dust will continuously accumulate on the surface of the atomizing nozzle and at the nozzle orifice. This accumulated coal dust will gradually block the nozzle orifice, resulting in a decrease in the spray pressure of the atomizing nozzle, a reduction in the spray range, and a deterioration in the atomization effect.

[0005] Therefore, an automatic spray dust suppression device for underground coal mine roadways is proposed to address the above-mentioned problems. Utility Model Content

[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] like Figures 1 to 5 As shown, this utility model provides an automatic spray dust suppression device for underground coal mine roadways, including a traveling vehicle 1, a water storage tank 12 installed on the upper surface of the traveling vehicle 1, and a connecting box 13 installed on the surface of the traveling vehicle 1.

[0027] The surface of the connecting box 13 is equipped with a nozzle storage assembly 2. The nozzle storage assembly 2 includes a connecting rod 21 installed on the upper surface of the connecting box 13, a storage tray 22 installed on the top of the connecting rod 21, a movable tray 23 for storing nozzles, a movable rod 1 24, a connecting plate 25, a movable rod 26, a moving block 27, and a spray nozzle 28.

[0028] The water storage tank 12 and the connecting box 13 are connected by a water pipe. The movable plate 23 is rotatably connected inside the storage plate 22. Multiple movable rods 24 are evenly installed on the upper surface of the storage plate 22. One end of the connecting plate 25 is rotatably connected to the movable rod 24. The moving block 27 is slidably connected in the groove opened inside the storage plate 22. The movable rod 26 is installed on the upper surface of the moving block 27. The other end of the connecting plate 25 is rotatably connected to the movable rod 26. The spray nozzle 28 is installed on the surface of the moving block 27 and is slidably connected to the nozzle opening opened on the surface of the storage plate 22, realizing the telescopic movement of the spray nozzle 28 inside the storage plate 22. This design allows the spray nozzle 28 to be stored inside the storage plate 22 when not in use, effectively preventing coal dust from directly accumulating on the nozzle surface.

[0029] The surface of the movable block 27 is connected to a water pipe 29. One end of the water pipe 29 passes through the movable block 27 and the storage tray 22 in sequence and is connected to the connecting box 13. The other end of the water pipe 29 is connected to the spray nozzle 28, so that water can be delivered to the spray nozzle 28 to spray water mist and reduce coal dust.

[0030] A servo motor 210 is installed inside the connecting rod 21. The output end of the servo motor 210 passes through the connecting rod 21 and the storage tray 22 in sequence and is connected to the movable tray 23, so that the spray nozzle 28 can be easily stored in the storage tray 22, further improving the use effect of the device.

[0031] A guide rod 211 is slidably connected in the through hole on the surface of the movable block 27. Both ends of the guide rod 211 pass through the movable block 27 and are installed in the groove inside the storage tray 22, thereby restricting the movement position of the movable block 27 and further improving the stability of the device during use.

[0032] A blocking component 3 is installed on the surface of the storage tray 22. The blocking component 3 includes a drive rod 31 installed at the center of the surface of the movable tray 23, a mounting plate 32 disposed on the surface of the storage tray 22, and a blocking plate 33 for blocking the nozzle.

[0033] One end of the drive rod 31 passes through the storage tray 22 and extends above the storage tray 22, and is connected to multiple mounting plates 32 set above the storage tray 22. The baffle plate 33 is installed on the surface of the mounting plate 32. After the spray nozzle 28 is stored, it can cover the nozzle opening of the storage tray 22, further enhancing the dustproof effect and solving the problem that the spray nozzle 28 is exposed and easily clogged.

[0034] The baffle 33 is located on the side of the surface of the storage tray 22 where the nozzle opening is opened, and the number of baffles 33 corresponds one-to-one with the spray nozzle 28, so as to protect the spray nozzle 28 from dust.

[0035] The structure of the vehicle 1, water tank 12 and spray nozzle 28 is prior art and is the same as the published patent, application number CN202120186903.9, "An Automatic Spray Dust Suppression Device for Coal Mines". For specific operation, please refer to the published patent.

[0036] Working principle and process: When spray dust suppression is required, the servo motor 210 is started first. The servo motor 210 drives the movable disk 23 to rotate in the collection tray 22. During the rotation of the movable disk 23, the transmission structure of the movable rod 1 24, the connecting plate 25 and the movable rod 26 pushes the moving block 27 to slide in the groove inside the collection tray 22. The guide rod 211 guides and stabilizes the moving block 27 to ensure that the moving block 27 and the spray nozzle 28 slide stably. The moving block 27 drives the spray nozzle 28 to slide out along the nozzle opening on the surface of the collection tray 22.

[0037] Meanwhile, during the rotation of the movable disc 23, the drive rod 31 drives the mounting plate 32 and the baffle plate 33 to rotate, so that the nozzle opening is removed from the obstruction of the baffle plate 33. The water guide pipe 29 on the surface of the movable block 27 remains connected to the connecting box 13, so that the water in the connecting box 13 can flow into the spray nozzle 28 through the water guide pipe 29. The spray nozzle 28 starts spraying to reduce dust in the tunnel.

[0038] The water storage tank 12 serves as a water storage device. The water in the tank is transported to the connecting box 13 via a water pump and water pipe. The connecting box 13 acts as a transfer and distribution water source, preparing for the subsequent water supply to the spray nozzle 28. When the spray nozzle 28 slides out into place, the water in the connecting box 13 flows into the spray nozzle 28 through the water guide pipe 29 under the action of the water pump, thereby realizing the spraying of water mist.

[0039] After the dust suppression operation is completed, the servo motor 210 rotates in the reverse direction, driving the movable disk 23 to rotate in the reverse direction. Through the transmission of movable rod 1 24, connecting plate 25 and movable rod 26, the moving block 27 drives the spray nozzle 28 to slide back into the storage disk 22 along the nozzle opening on the surface of the storage disk 22. When the spray nozzle 28 has completely slid back, the baffle plate 33 then covers the nozzle opening again to prevent coal dust from accumulating on the surface of the spray nozzle 28 and at the spray hole, reducing the risk of clogging.

[0040] Whether in narrow tunnels or wide transport tunnels, the traveling vehicle 1 can move flexibly to achieve targeted dust suppression, making it convenient to carry out dust suppression operations in the tunnels.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
