Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology in coal mines, and more particularly to a dust suppression device for open-pit coal mines. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. Open-pit coal mines refer to coal seams deposited on the surface or in shallow layers due to geographical changes, and are mined directly from the open. Open-pit mining can obtain a larger proportion of coal compared to underground mining because more ore seams are utilized. Open-pit coal mines can cover an area of ​​tens of square kilometers.

[0003] In the coal mining industry, due to the increasing mechanization of coal production and the continuous improvement of mining intensity, various operations such as drilling, blasting, loading and unloading, crushing, and transportation generate a large amount of coal dust. This results in a harsh working environment in coal mines, endangering human health. With the increasing demand for energy and industrial products, the impact of dust hazards is gradually increasing. Therefore, workers generate a large amount of dust when mining in open-pit coal mines, and dust is also generated when storing mined coal in open-pit areas, causing significant environmental pollution.

[0004] In related technologies, dust suppression water mist is generally only slightly higher than that of coal mines, and cannot suppress dust that drifts high up. At the same time, existing dust suppression devices are large in size, and after a long period of dust suppression, the road surface becomes muddy, making it inconvenient to move the devices.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0046] Before providing a further detailed description of the embodiments of this utility model, the directional terms used in the embodiments of this utility model, such as "upper part", "lower part" and "side part", do not have the meaning of limiting the scope of protection of this utility model.

[0047] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0048] Figure 1 This is a schematic diagram of a dust suppression device for an open-pit coal mine according to an embodiment of the present invention.

[0049] like Figure 1 As shown, one embodiment of this utility model provides a dust suppression device 100 for open-pit coal mines. The dust suppression device 100 includes:

[0050] The walking unit 120 includes a connecting frame 121, on which a water tank 110 is provided;

[0051] A water tank 110 is mounted on the walking part 120 and is located on the connecting frame 121. A water pump 180 is mounted on the side of the water tank 110 away from the walking part 120. The two ends of the water pump 180 are respectively connected to an inlet pipe 150 and an intermediate connecting pipe 170. The other end of the inlet pipe 150 is located inside the water tank 110, and the other end of the intermediate connecting pipe 170 is connected to an outlet pipe 160.

[0052] The lifting part 130 is installed on the water tank 110. The end of the lifting part 130 away from the water tank 110 is provided with a bearing part 140, and the intermediate connecting pipe 170 is installed on the bearing part 140.

[0053] The dust suppression device 100 includes a walking part 120, a water tank 110 mounted on the walking part 120, and a lifting part 130 mounted on the water tank 110. The water tank 110 is equipped with a water pump 180. The inlet of the water pump 180 is connected to the inlet pipe 150, and the outlet of the water pump 180 is connected to the intermediate connecting pipe 170. The other end of the intermediate connecting pipe 170 is connected to the outlet pipe 160. The other end of the inlet pipe 150 is located inside the water tank 110. Under the power of the water pump 180, the water in the water tank 110 enters the inlet pipe 150, the intermediate connecting pipe 170, and the outlet pipe 160 in sequence, and is sprayed out from the outlet pipe 160 to achieve dust suppression in open-pit coal mines. The supporting part 140 provides support for the intermediate connecting pipe 170. Driven by the lifting part 130, the height of the intermediate connecting pipe 170 above the ground changes, thereby changing the height of the water outlet pipe 160. This allows the dust suppression device 100 to adjust the dust suppression height, suppressing dust at different heights. The walking part 120 facilitates the movement of the dust suppression device 100 on muddy roads, improving its reliability and stability in open-pit coal mines.

[0054] Specifically, the lifting part 130 allows staff to adjust the height of the intermediate connecting pipe 170 and the water outlet pipe 160 according to the actual situation, so that the water outlet pipe 160 can suppress dust at different heights. At the same time, the lifting part 130 can ensure the stability and reliability of the support of the bearing part 140.

[0055] It should be noted that water column outlets can be installed at both ends of the water outlet pipe 160, and multiple water mist outlets are provided on the side wall of the water outlet pipe 160. Valves can be installed at both the water column outlets and the water mist outlets, allowing operators to control the water spraying from the outlet pipe to form water mist and / or water columns as needed, covering and suppressing surrounding dust. The diameter of the water column outlet can be larger, while the diameter of the water mist outlet is smaller. Water mist is formed by pressurization, which is existing technology and will not be elaborated further.

[0056] Figure 4 This is a schematic diagram of a water tank and a lifting unit according to an embodiment of the present invention; Figure 5 This is a schematic diagram of the lifting part and the supporting part according to an embodiment of the present invention.

[0057] In one feasible implementation, such as Figure 4 and Figure 5 As shown, the lifting unit 130 includes:

[0058] The load-bearing rod 131 is fixedly installed on the side of the water tank 110 away from the walking part 120. The load-bearing rod 131 is a hollow rod, and the end of the load-bearing rod 131 away from the water tank 110 is provided with a first threaded hole.

[0059] The telescopic rod 132 is installed inside the load-bearing rod 131. The telescopic rod 132 is provided with multiple second threaded holes, which are aligned with the first threaded holes.

[0060] Fastening post 133, having external threads, passes through the first threaded hole and the second threaded hole; or

[0061] The lifting unit 130 is an electric telescopic rod, and the water tank 110 is equipped with a storage battery, which powers the electric telescopic rod.

[0062] The load-bearing rod 131 is mounted on the water tank 110, and a telescopic rod 132 is inserted into the load-bearing rod 131. A fastening post 133 passes through the side of the load-bearing rod 131 and is threadedly connected to the telescopic rod 132. The height of the lifting unit 130 can be adjusted by connecting the fastening post 133 to second threaded holes of different heights. The end of the telescopic rod 132 away from the load-bearing rod 131 is fixedly connected to the bearing unit 140, which supports the intermediate connecting pipe 170. By adjusting the height of the telescopic rod 132 inside the load-bearing rod 131, the height of the intermediate connecting pipe 170 from the ground can be adjusted, thereby adjusting the height of the water outlet pipe 160 connected to the intermediate connecting pipe 170 and expanding the dust suppression height range of the dust suppression device 100.

[0063] In addition, the lifting unit 130 can also be an electric telescopic rod, a hydraulic telescopic rod, or a pneumatic telescopic rod. These are all existing integral components and will not be described in detail here.

[0064] Understandably, the intermediate connecting pipe 170 and the outlet pipe 160 are connected by threads for easier assembly and disassembly. At least part of the intermediate connecting pipe 170 is a pleated pipe or a flexible hose; typically, a portion stored above the water tank 110 can be a pleated pipe or a flexible hose. This ensures the feasibility of raising the outlet pipe 160 when the lifting unit 130 is raised or lowered. In other words, the intermediate connecting pipe 170 on the supporting unit 140 remains stationary, and the height adjustment of the lifting unit 130 relies on the remaining portion of the intermediate connecting pipe 170 on the water tank 110.

[0065] Figure 2This is a schematic diagram of the walking section according to an embodiment of the present invention.

[0066] In one feasible implementation, such as Figure 2 As shown, the walking unit 120 includes:

[0067] The connecting frame 121 includes a support plate 1211 and connecting rods 1212 disposed on both sides of the support plate 1211.

[0068] Rollers 122 are located at both ends of the connecting rod 1212, and the rollers 122 are provided with locking blocks in the circumferential direction;

[0069] The first motor 123 has its output shaft fixedly connected to the central shaft of the roller 22.

[0070] Track 124 is overlaid on roller 122. Multiple slots are provided on the side of track 124 facing roller 122, and the slots match the blocks.

[0071] The arrangement of the connecting frame 121, the first motor 123, the rollers 122, and the track 124 increases the contact area between the dust suppression device 100 and the ground, improving its stability and grip, and facilitating smooth movement on muddy surfaces. The first motor 123 drives the rollers 122 to rotate within the track 124, and the rotational motion of the first motor 123 is converted into linear motion through the engagement of locking blocks and slots.

[0072] It should be noted that four rollers 122 are usually provided to support the water tank 110 and the tracks 124. Since it needs to be used in an open coal mine, the terrain is relatively complex and muddy. Therefore, this application uses four first motors 123 to drive the four rollers 122, which can increase the walking power of the walking part 120 and further improve the reliability and stability of the dust suppression device 100. The first motors 123 are usually located in the lower space of the water tank 110, that is, inside the pair of tracks 124.

[0073] Furthermore, the steering of the tracks 124 can create a speed difference between the rollers 122 within the two tracks 124, thus enabling the tracks 124 to turn. This is similar to the principle used in tanks and excavators, and will not be elaborated further. The arrangement of four first motors 123, by controlling their different speeds, also facilitates turning and movement of the tracks 124.

[0074] Figure 3 This is a connection diagram of a connecting frame according to an embodiment of the present invention.

[0075] In one feasible implementation, such as Figure 3 As shown, the connecting rod 1212 has limiting plates 125 at both ends. The limiting plate 125 includes a pair of parallel plates and a transition plate for connecting the pair of parallel plates. The transition plate is fixedly connected to the connecting rod 1212. The roller 122 is disposed between the pair of parallel plates. The parallel plates are provided with limiting holes. The central axis of the roller 122 is rotatably connected to the limiting holes.

[0076] The connecting frame 121 includes a support plate 1211 and connecting rods 1212. The pair of parallel connecting rods 1212 are connected via the support plate 1211. Rollers 122 are provided at both ends of the connecting rods 1212. The central axis of the rollers 122 is fixedly connected to the output shaft of the first motor 123, which can be a threaded connection or a screw connection. A limiting plate 125, U-shaped, is provided on the connecting rods 1212 for limiting rotation. The limiting plate 125 supports the rollers 122, ensuring the stability of their rotation.

[0077] In one feasible implementation, such as Figure 3 As shown, a second motor 126 is provided on the support plate 1211. The second motor 126 is covered with a protective shell 127. The output shaft of the second motor 126 is located outside the protective shell 127. The second motor 126 is configured to drive the water tank 110 to move on the walking part 120.

[0078] A second motor 126 is mounted on the support plate 1211. The second motor 126 is covered by a protective shell 127. The protective shell 127 serves two purposes: firstly, it protects the second motor 126, preventing it from being exposed; secondly, it supports the water tank 110, making it more stable as it moves with the dust suppression device 100. The movement of the water tank 110 on the traveling unit 120 is only a directional description; it is understood that the water tank 110 and the traveling unit 120 do not actually contact each other in this application.

[0079] In one feasible implementation, a gear is provided on the output shaft of the second motor 126, and a connecting groove is provided on the side of the water tank 110 facing the walking part 120. A pair of racks are arranged opposite each other in the connecting groove, and the gear meshes with the pair of racks.

[0080] A gear is installed on the output shaft of the second motor 126, and a rack is installed on the water tank 110. The rotational motion of the second motor 126 is converted into linear motion through the cooperation of the gear and rack, facilitating the reciprocating movement of the water tank 110 on the protective shell 127. When the traveling part 120 is fixed in a certain position, dust can be reduced within a certain range at a certain position by moving the water tank 110 forward and backward, without the need to repeatedly control the movement of the traveling part 120, thus reducing the energy consumption of the multiple first motors 123.

[0081] It is understandable that the first motor 123, the second motor 126 and the third motor 146 can be equipped with motors with their own batteries, or the dust suppression device 100 can be equipped with a storage battery to power each motor. This is existing technology and will not be elaborated further.

[0082] In one feasible implementation, such as Figure 4 and Figure 5 As shown, the support portion 140 includes:

[0083] The support plate 141 includes an inclined plate and a clamping plate disposed at one end of the inclined plate, and the other end of the inclined plate is connected to the end of the telescopic rod 132 away from the water tank 110.

[0084] Connecting plate 142, one end of which is connected to clamping plate;

[0085] A fixing plate 143 is provided at the other end of the connecting plate 142. A positioning frame 144 is provided on the fixing plate 143. The positioning frame 144 is configured to fix the water outlet pipe 160. The positioning frame 144 is fixedly connected to the fixing plate 143 by a pin 145.

[0086] The support plate 141 includes an inclined plate and a clamping plate connected to each other. The end of the inclined plate away from the clamping plate is fixedly connected to the telescopic rod 132. The clamping plate is U-shaped and is used to limit the connection plate 142. The inclined plate allows the connection plate 142 to be basically parallel to the water tank 110. It also provides a transition position for the intermediate connecting pipe 170, preventing the intermediate connecting pipe 170 from being directly set on the connection plate 142 and causing excessive friction with the telescopic rod 132, which would affect the service life of the intermediate connecting pipe 170.

[0087] It should be noted that a fixing plate 143 is provided at the end of the connecting plate 142 away from the clamping plate. The fixing plate 143 is usually set at an angle to the connecting plate 142. This ensures that both the water column outlet and the water mist outlet on the water outlet pipe 160 face the side of the dust suppression device 100, thereby improving the dust suppression efficiency. In this application, the fixing plate 143 is set perpendicular to the water tank 110.

[0088] In addition, a positioning bracket 144 is provided on the fixing plate 143. The positioning bracket 144 is sleeved on the water outlet pipe 160 to position the water outlet pipe 160. Then, the positioning bracket 144 is fixedly connected to the fixing plate 143 by a pin 145, which improves the stability of the water outlet pipe 160 and avoids the water flow from causing the water outlet pipe 160 to shake, thus affecting the dust suppression effect. At the same time, it also makes it easier to install the water outlet pipe 160 on the fixing plate 143.

[0089] In one feasible implementation, such as Figure 5As shown, the bearing part 140 also includes a third motor 146, the output shaft of the third motor 146 is rotatably connected to the clamping plate, and the output shaft of the third motor 146 is fixedly connected to the connecting plate 142.

[0090] The clamping plate is U-shaped, which facilitates the engagement of the connecting plate 142, meaning the connecting plate 142 is positioned within the opening of the clamping plate. The output shaft of the third motor 146 is rotatably connected to the clamping plate, and simultaneously fixedly connected to the connecting plate 142. This allows the rotation of the third motor 146 to drive the rotation of the connecting plate 142 on the support plate 141, thereby adjusting the spray angle of the water outlet pipe 160 to suit different situations. This achieves circumferential dust suppression without requiring the turning of the traveling part 120.

[0091] Figure 6 This is a schematic diagram of a connecting plate according to an embodiment of the present invention.

[0092] In one feasible implementation, such as Figure 6 As shown, the support portion 140 also includes:

[0093] Fixed shell 147, multiple fixed shells 147 are disposed on inclined plate and connecting plate 142, fixed shell 147 is arc-shaped, and intermediate connecting pipe 170 is disposed inside fixed shell 147;

[0094] The threaded post 148 is threadedly connected to the fixed shell 147, and the threaded post 148 abuts against the intermediate connecting pipe 170.

[0095] A fixing shell 147 is provided on the inclined plate and the connecting plate 142. The fixing shell 147 is usually arc-shaped and matches the intermediate connecting pipe 170 to limit the intermediate connecting pipe 170. At the same time, the threaded post 148 passes through the fixing shell 147 and abuts against the intermediate connecting pipe 170 to ensure the basic fixation of the intermediate connecting pipe 170 and prevent the intermediate connecting pipe 170 from falling off the bearing part 140 due to the vibration of water flow and water pump 180. In other words, it ensures the reliability and effectiveness of the connection of the intermediate connecting pipe 170.

[0096] Understandably, the fixed housing 147 allows for the snap-fit ​​connection of the intermediate connecting pipe 170. Workers can adjust the length of the threaded post 148 extending into the fixed housing 147 according to the dimensions of the intermediate connecting pipe 170, thus achieving a fixed and limited position for the intermediate connecting pipe 170. Typically, the intermediate connecting pipes 170 are equidistantly spaced.

[0097] In one feasible embodiment, the water tank 110 is provided with a water inlet 113, the water inlet 113 is provided with a rubber stopper 114, the water tank 110 includes a top cover 111, and the top cover 111 is provided with a groove 112.

[0098] The water tank 110 features an inlet 113 for easy water filling. After filling, the inlet 113 is sealed with a rubber stopper 114 to prevent water leakage. The top cover 111 seals the water tank 110, protecting the water quality and preventing impurities from entering. A groove 112 on the top cover 111 allows for easy cleaning, preventing rust and extending the tank's lifespan.

[0099] It is understandable that the connection between the top cover 111 and the water tank 110 can be achieved by setting a boss inside the water tank 110, with the boss parallel to the bottom plate of the water tank 110, and the top cover 111 being supported by the boss, and then the top cover 111 being fixedly connected to the boss by a connector; or multiple grooves or protrusions can be set on the side of the boss facing the top cover 111, and protrusions or grooves can be set on the side of the top cover 111 facing the boss, with the protrusions and grooves matching and interlocking to ensure the limiting and fixing of the top cover 111.

[0100] It is understood that the electrical components appearing in this application are electrically connected to an external controller, which can be a computer or a conventional remote control device, and will not be elaborated further. Each motor can also be electrically connected to 220V AC mains power, and will not be elaborated further. Additionally, each motor can be equipped with a support frame, which is typically connected to a fixing component near the motor to support it and prevent excessive motor vibration from affecting its lifespan. These are all conventional techniques in the field and will not be elaborated further.
