Description

Technical Field

[0001] This invention relates to the technical field of coal slime cleaning, and more specifically, to a coal mine underground drainage ditch cleaning device. Background Technology

[0002] The drainage ditches in the main transport roadways of coal mines are crucial drainage channels. However, during the drilling processes for geological exploration, anti-outburst extraction, and scientific research, large amounts of drill cuttings, mud, coal slurry, and coal dust are generated. These materials accumulate at the bottom of the ditches, gradually overflowing and causing blockages in the drainage channels and water accumulation in the roadways. This affects the mine's safety and quality standards and poses safety hazards to personnel and equipment. Especially in coal mines with soft coal seams, borehole collapse is often severe when using water for slag removal, making it easier for coal slurry to accumulate in the ditches. Direct pumping of this slurry can easily cause blockages in the main transport roadways and main water tanks, negatively impacting the safety and efficiency of underground operations in the long run.

[0003] In existing technologies, cleaning coal sludge from underground main transport roadways relies on manual labor using handheld tools such as shovels for retrieval, shoveling, and bagging. However, due to environmental limitations such as confined spaces, manual operation is inconvenient and difficult to thoroughly clean, easily leading to the residue of sludge and debris. Moreover, workers need to use handheld tools for extended periods while bending over, resulting in extremely high labor intensity. The daily cleaning range for a single person is also limited, leading to low efficiency. When working around narrow, deeply sludge-laden ditches, there is also a high risk of slipping, bumping, and other safety accidents. In short, manual cleaning of coal sludge from ditches is time-consuming, labor-intensive, difficult to thoroughly clean, and unsafe. Summary of the Invention

[0004] The purpose of this invention is to provide a coal mine underground water ditch cleaning device to solve the technical problems of the prior art, which is time-consuming, labor-intensive, difficult to clean thoroughly, and unsafe to clean coal sludge in water ditches manually.

[0005] The present invention provides a coal mine underground drainage ditch cleaning device, which includes a cleaner that can be mounted across the drainage ditch. The cleaner includes a walking mechanism and a support platform that is vertically mounted on the walking mechanism. The walking mechanism can walk along the edge of the drainage ditch. The support platform is equipped with a slurry pump, which is used to pump slurry from the drainage ditch and transport it to a target location.

[0006] The coal mine underground water ditch cleaning equipment provided by this invention can produce the following beneficial effects: The coal mine underground drainage ditch cleaning equipment provided by this invention has a cleaner that can be mounted across the drainage ditch. The cleaner's traveling mechanism drives the entire cleaner along the ditch. A slurry pump supported by the cleaner's carrying platform pumps out the slurry from the ditch. The slurry pump can rise and fall with the carrying platform, thus pumping out coal sludge deposited at different depths at the bottom of the ditch, including sludge from hidden areas such as depressions at the bottom of the ditch. This improves the thoroughness of the cleaning and effectively ensures the cleaning effect. In other words, the cleaning equipment provided by this invention has a slurry pump that can move along the ditch under the drive of the traveling mechanism and rise and fall under the drive of the carrying platform. Therefore, it can clean coal sludge from different locations in the ditch. Compared with manual cleaning, it can greatly save manpower, improve efficiency, ensure cleaning effect, and has high safety.

[0007] Furthermore, the carrying platform is also equipped with a stirring device, which is located around the slurry pump inlet. The stirring device agitates the coal slurry deposited at the bottom of the ditch and the coal dust floating on the water surface, enabling the slurry pump to remove the coal slurry, coal dust, and other debris from the ditch. This effectively prevents the slurry pump from clogging, thus ensuring the normal progress of the cleaning work.

[0008] Furthermore, the mixing device includes two mixers, which are respectively arranged on both sides of the slurry pump. The two mixers respectively agitate the water between the slurry pump and the ditch wall on their respective sides, so that the slurry pump can pump out coal slurry and other materials from various locations in the ditch from the width direction of the ditch.

[0009] Furthermore, the carrying platform is also equipped with a scraper blade, positioned behind the slurry pump along the travel direction of the cleaner. The shape of the scraper blade matches the cross-sectional shape of the ditch, and is used to scrape up the sludge from the bottom and sides of the ditch. The scraper blade is roughly U-shaped. As the traveling mechanism drives the entire cleaner forward, the scraper blade can scrape the coal sludge from the bottom and sides of the ditch to the side closer to the slurry pump and mixer, thereby facilitating agitation by the mixer and pumping out by the slurry pump, further improving the thoroughness of the cleaning.

[0010] Furthermore, the support platform is also equipped with gripping claws, which are positioned in front of the slurry pump along the travel direction of the cleaner. By continuously gripping drill cuttings, mud, floating coal dust, and other debris in the ditch with the gripping claws positioned in front of the slurry pump's travel direction, the slurry pump can extract debris more conveniently and effortlessly.

[0011] Furthermore, the cleaning device also includes a track laid along the edge of the ditch, and a traveling mechanism including a traveling wheel. One of the track and the traveling wheel is provided with a groove, and the other is movably embedded in the groove. The sidewall of the groove limits the traveling wheel, making it difficult for the traveling wheel to detach from the track, thereby preventing the cleaner from detaching from the edge of the ditch.

[0012] Furthermore, the walking mechanism also includes a clamping arm, which is clamped to the edge of the ditch, and an anti-slip pad is provided on the inner side of the clamping arm. The clamping arm can reliably install the cleaner on the edge of the ditch, and the anti-slip pad, such as a rubber pad, attached to its inner side can effectively prevent wear on the edge of the ditch during clamping, and can also increase the friction between the cleaner and the edge of the ditch, effectively preventing the cleaner from shifting or slipping during movement or cleaning, and ensuring operational stability.

[0013] Furthermore, lifting columns are installed between each wheel of the carrying platform and the traveling mechanism, and these lifting columns are used to drive the carrying platform to rise and fall. By lifting the carrying platform, the slurry pump, stirring device, and scraper on it can be raised and lowered, thereby adapting to the cleaning of ditches of different depths and coal slurry of different thicknesses.

[0014] Furthermore, the cleaning equipment also includes a transport vehicle, which travels alongside the cleaner and receives the slurry delivered by the slurry pump. Through the mine car collection structure in conjunction with the cleaner, direct and continuous cleaning can be achieved, simultaneously removing floating coal from the water surface and scraping away sedimented coal sludge from the bottom of the trench. The cleaning efficiency is 3-5 times higher than manual labor, significantly reducing the number of underground workers and their physical exertion.

[0015] Furthermore, the transport vehicle is equipped with a filtration device and a drainage device. The filtration device is used to filter the slurry delivered by the slurry pump, and the drainage device is used to discharge the filtered water into a ditch. By filtering the slurry delivered by the slurry pump, the water and coal slime are separated, allowing the ditch and the transport vehicle to fully perform their respective drainage and transport functions.

[0019] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0020] This embodiment provides a coal mine underground water ditch cleaning device, such as... Figure 1 As shown, the cleaning equipment includes a cleaner that can be mounted across a ditch 900, a walking mechanism, and a lifting platform 300 mounted on the walking mechanism. The walking mechanism can travel along the edge of the ditch. The lifting platform 300 is equipped with a slurry pump 400, which is used to pump slurry from the ditch and transport it to the target location.

[0021] The coal mine underground drainage ditch cleaning equipment provided in this embodiment has a cleaner that can be mounted across the drainage ditch. The cleaner's traveling mechanism can drive the entire cleaner along the ditch. The slurry pump 400, carried by the cleaner's support platform 300, can pump out the slurry in the ditch. The slurry pump 400 can rise and fall with the support platform 300, thereby pumping out coal sludge deposited at different depths at the bottom of the ditch, and also pumping out coal sludge from hidden areas such as recessed areas at the bottom of the ditch. This improves the thoroughness of the cleaning and effectively ensures the cleaning effect. In other words, the cleaning equipment provided in this embodiment has a slurry pump 400 that can move along the ditch under the drive of the traveling mechanism and can also rise and fall under the drive of the support platform 300. Therefore, it can clean coal sludge in different locations in the ditch. Compared with manual cleaning, it can greatly save manpower, improve efficiency, ensure cleaning effect, and has high safety.

[0022] Specifically, in this embodiment, the supporting platform 300 is also equipped with a stirring device, which is located around the slurry pump 400 inlet. With this arrangement, the stirring device agitates the coal slurry deposited at the bottom of the ditch and the coal dust floating on the water surface, enabling the coal slurry, coal dust, and other debris in the ditch to be sucked away by the slurry pump 400. This effectively prevents the slurry pump 400 from clogging, thus ensuring the normal progress of the cleaning work.

[0023] Specifically, in this embodiment, the mixing device includes two mixers, which are respectively arranged on both sides of the slurry pump 400. In this arrangement, the two mixers respectively mix the water between the slurry pump 400 and the ditch wall on their respective sides, so that the slurry pump 400 can pump coal slurry and other materials from various locations in the ditch width direction. Of course, it should be noted that in other embodiments of this application, the number of mixers is not limited to two. For example, there can be four mixers, which can be arranged around the slurry pump 400's inlet. For example, the four mixers can be located on the left and right sides, and at the left front and right front of the slurry pump 400, respectively. Of course, this embodiment can also directly use a submersible slurry pump with a mixing mechanism.

[0024] It should also be noted that if the ditch is relatively wide, a more powerful slurry pump 400 can be installed to ensure the effective removal and cleaning of coal slime. Alternatively, a horizontal moving mechanism can be installed to drive the bearing platform 300 to move along the width of the ditch, ensuring that the mixing device and the slurry pump 400 can clean all parts of the ditch along its width.

[0025] Specifically, in this embodiment, the support platform 300 is also equipped with a scraper blade, which is positioned behind the slurry pump 400 along the travel direction of the cleaner. The shape of the scraper blade matches the cross-sectional shape of the ditch and is used to scrape up the sludge at the bottom and sides of the ditch. In this configuration, the scraper blade is roughly U-shaped. As the traveling mechanism drives the entire cleaner forward, the scraper blade can scrape the coal sludge at the bottom and sides of the ditch to the side closer to the slurry pump 400 and the mixer, thereby facilitating the mixing by the mixer and the pumping by the slurry pump 400, further improving the thoroughness of the cleaning.

[0026] More specifically, in this embodiment, the scraper can be made of stainless steel and can be installed on the housings of two mixers. Preferably, the angle of the scraper is adjustable, for example, it can be adjusted within the range of 0° to 30°, so as to accurately fit the bottom of the ditch and the sides of the ditch and scrape off the attached silt, stubborn stains and floating coal dust.

[0027] Specifically, in this embodiment, the support platform 300 is also equipped with gripping claws, which are positioned in front of the slurry pump 400 along the travel direction of the cleaner. With this configuration, the gripping claws positioned in front of the slurry pump 400 continuously grab drill cuttings, silt, floating coal dust, and other debris from the ditch, allowing the slurry pump 400 to extract the debris more conveniently and effortlessly. More specifically, the gripping claws can be rotating debris-grabbing claws, thus simultaneously grabbing and stirring the debris.

[0028] Specifically, in this embodiment, the cleaning device further includes a track 800, which is laid along the edge of the ditch. The walking mechanism includes a walking wheel 100, which is provided with a groove and is a grooved wheel. The track 800 is embedded in the groove of the walking wheel 100. In this configuration, the sidewall of the groove limits the walking wheel 100, making it difficult for the walking wheel 100 to detach from the track 800, thereby preventing the cleaner from detaching from the edge of the ditch. Of course, in other embodiments of this application, the groove can also be provided on the track 800, and the walking wheel 100 can be movably embedded in the groove of the track 800. In this case, the sidewall of the groove can also limit the walking wheel 100, making it difficult for it to detach from the track 800.

[0029] Specifically, in this embodiment, the walking mechanism further includes a clamping arm, which is clamped to the edge of the ditch, and an anti-slip pad is provided on the inner side of the clamping arm. With this configuration, the clamping arm can reliably mount the cleaner to the edge of the ditch, and the anti-slip pad, such as a rubber pad, attached to its inner side effectively prevents wear on the edge of the ditch during clamping and increases the friction between the cleaner and the edge of the ditch, effectively preventing the cleaner from shifting or slipping during movement or cleaning, thus ensuring operational stability.

[0030] More specifically, in this embodiment, clamping arms are provided on both sides of the cleaner to clamp the edges of the water ditch on both sides, thus effectively ensuring the overall stability of the cleaner in both stationary and moving states.

[0031] That is, this embodiment adopts the "edge fixed-track moving" structure, that is, it is fixed to the edge and moves along the track 800, and the fixing structure adopts the "double-sided clamping + anti-slip buffer" structure. It does not require manual hand operation throughout the process. Under the control of the control system or the operation of the staff, it can move along the track 800 of the ditch edge and complete all-round cleaning.

[0032] Furthermore, the clamping arm includes inner and outer clamping plates disposed on the base of the walking mechanism, and the positions of both clamping plates are adjustable so that the distance between them can be adjusted within a range of 5 to 20 cm. Thus, the clamping arm can adapt to the ditch within a certain width range and the edge of the ditch with different edge widths within the adjustment range.

[0033] In this embodiment, the walking mechanism also includes a miniature servo motor mounted on the base of the walking mechanism. The motor controls the moving speed to be 0.1~0.3m / s via gear transmission, which can be flexibly adjusted according to the density of debris accumulation. Simultaneously, the walking mechanism is also equipped with a travel limit sensor. When the device moves to the end of the ditch, it automatically triggers reverse movement or stops to prevent the device from deviating from the working trajectory. Of course, the cleaning equipment provided in this embodiment can also have a steering function to adapt to the direction of the ditch; the specific structure can use existing technology and will not be described in detail here.

[0034] Specifically, in this embodiment, as Figure 1 As shown, lifting columns 200 are provided between the carrying platform 300 and each traveling wheel 100 of the traveling mechanism. The lifting columns 200 are used to drive the carrying platform 300 to rise and fall. By lifting the carrying platform 300, the slurry pump, mixing device, and scraper on it can be raised and lowered, thereby adapting to the cleaning of ditches of different depths and coal slurry of different thicknesses. More specifically, in this embodiment, the lifting column 200 is a telescopic column. Furthermore, it can be a telescopic column that is manually adjustable, or it can be a telescopic column that is hydraulically, pneumatically, or electrically driven. That is, as long as the height of the carrying platform 300 can be adjusted according to the working requirements of the slurry pump 400, the specific structural form of this embodiment is not limited.

[0035] Specifically, in this embodiment, the following continues... Figure 1 As shown, the cleaning equipment also includes a transport vehicle 600, such as a mine car. The transport vehicle 600 travels alongside the cleaner and receives the slurry delivered by the slurry pump 400. Thus, the cleaning equipment provided in this embodiment, through mechanical transmission and the mine car collection structure, can directly and continuously clean, simultaneously completing the retrieval of floating coal on the water surface and the scraping of coal sludge settled at the bottom of the trench. The cleaning efficiency can be increased by 3 to 5 times compared to manual labor, which can significantly reduce the number of underground workers and physical exertion.

[0036] Specifically, in this embodiment, the transport vehicle 600 is equipped with a filtration device and a drainage device. The filtration device is used to filter the slurry delivered by the slurry pump 400, and the drainage device is used to discharge the filtered water into a ditch. By filtering the slurry delivered by the slurry pump 400, water and coal slime are separated, allowing the ditch and the transport vehicle to fully perform their respective drainage and transport functions. More specifically, in this embodiment, the filtration device may include a filter screen, and further, may sequentially include a coarse filter screen with large mesh and a fine filter screen with small mesh, to perform graded filtration of the slurry delivered by the slurry pump 400. This effectively avoids mesh blockage caused by unsuitable mesh size, thereby ensuring smooth filtration and guaranteeing filtration and cleaning efficiency. Combining the gripping claw, the mixer, and the scraper, the cleaning equipment in this embodiment achieves a triple processing function of "pre-gripping + mid-stage mixing and scraping + post-filtration".

[0037] Of course, the cleaning device provided in this embodiment also includes a control device 800, which can adjust and control the cleaning speed, pumping speed, etc. of the cleaner via a remote control. This part can be achieved using existing technology, so it will not be described in detail.

[0038] In summary, this embodiment provides a coal mine underground drainage ditch cleaning device. Through targeted technical means, it precisely solves the multiple problems of traditional manual cleaning, such as difficulty in reaching hidden areas like floating coal and bottom depressions in the drainage ditch, incomplete cleaning, and the easy blockage of the drainage ditch by residual coal sludge, as well as high labor intensity and low efficiency. It mainly includes a traveling mechanism with wheels 100 and clamping arms, a support platform 300 for support and lifting, a core device on the support platform 300—a submersible slurry pump 400—along with a mixer, gripping claws, and scraper, as well as connected slag discharge pipes 500, electrical wires, and matching mine cars. Through the coordinated operation of these structures, it can perform integrated operations of "stable fixing - precise movement - efficient cleaning," realizing the agitation, collection, and transportation of coal sludge. Moreover, by setting up lifting columns 200 and moving tracks 800, the cleaner can penetrate deep into the crevices at the bottom of the ditch to scrape away stubborn sediment and efficiently intercept and clean floating coal dust on the water surface, achieving a cleaning thoroughness of over 95%. This effectively prevents coal sludge from clogging the drainage ditch and ensures the smooth flow of the underground drainage system.
