[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] like Figure 1As shown, an embodiment of the present invention provides a drainage device, comprising a tank body 10, a first filter plate 21, and a drainage assembly. The tank body 10 has a cavity for storing drainage water. The tank body 10 also includes a water inlet 11 and a drain outlet 12. The water inlet 11 is disposed at the top of the tank body 10, and both the water inlet 11 and the drain outlet 12 are connected to the cavity. The first filter plate 21 is disposed within the cavity, and the first filter plate 21 covers the water inlet 11. The first filter plate 21 is capable of filtering coal slag from the water. The drainage assembly is disposed within the cavity and below the first filter plate 21. The drainage assembly includes a water pump 31 and a liquid level sensor. The water pump 31 is electrically connected to the liquid level sensor, which is capable of sensing the liquid level within the cavity. The drain outlet 12 is connected to the water pump 31, and the liquid level sensor is capable of controlling the operation of the water pump 31 based on the detected water level, thereby pumping the fluid within the cavity out of the drain outlet 12.

[0045] Using the technical solution of the present utility model, the drainage device includes a tank body 10, a first filter plate 21, and a drainage assembly. The tank body 10 has a cavity within it for storing drainage water. The tank body 10 also includes a water inlet 11 and a drain outlet 12. Water enters through the water inlet 11, passes through the first filter plate 21, and then enters the cavity. The first filter plate 21 covers the water inlet 11 and filters coal slag from the fluid, thereby reducing the possibility of coal slag entering the water pump and extending the pump's service life. The drainage assembly is located within the cavity and below the first filter plate 21. The drainage assembly includes a water pump 31 and a liquid level sensor. The water pump 31 is electrically connected to the liquid level sensor, and the drain outlet 12 is connected to the water pump 31. The liquid level sensor senses changes in the liquid level within the cavity and, based on the detected water level, controls the water pump 31 to pump the water out of the cavity through the drain outlet 12, thereby achieving automated management of mine drainage and effectively improving drainage efficiency and safety. The liquid level sensor ensures that the start of the water pump 31 can be accurately controlled at different water levels, avoiding equipment damage caused by too high a water level and waste of resources caused by too low a water level.

[0046] like Figure 4 As shown, the drainage device also includes a collection portion. The tank body 10 also has a first slag discharge port 41, which is located at the bottom of the tank body 10 and communicates with the cavity. The first slag discharge port 41 is used to discharge the coal slag at the bottom of the cavity. In this embodiment, the drainage device also includes a collection portion that can collect small particles of coal slag in the water body that pass through the first filter plate 21, as well as sludge formed by small particles of coal slag, sand, gravel, and soil. The provision of the collection portion facilitates slag discharge within the cavity.

[0047] Furthermore, the drainage device also includes a second filter plate 22, which is arranged in the cavity and located below the first filter plate 21. The second filter plate 22 divides the cavity into a first chamber and a second chamber that are interconnected. The first chamber and the second chamber are distributed sequentially along the vertical direction. A first chamber is formed between the first filter plate 21 and the second filter plate 22. The first chamber is connected to the drain port 12. The second filter plate 22 cooperates with the bottom of the pool body 10 to form a second chamber, and the second chamber is connected to the first slag discharge port 41.

[0048] In this embodiment, a second filter plate 22 is provided within the cavity. The second filter plate 22 is positioned below the first filter plate 21 and cooperates with the bottom of the tank body 10 to form a second chamber. After being filtered by the first filter plate 21, the water contains only small particles of coal slag, sand, gravel, and soil. These particles are deposited by gravity in the second chamber formed by the bottom of the tank body 10 and the second filter plate 22, forming sludge. The second filter plate 22 blocks the sludge in the second chamber, ensuring that the first chamber is kept in an environment with minimal solids. This, in turn, ensures the proper operating environment for the water pump 31 and extends its service life. The tilted bottom of the tank body 10 allows small particles of coal slag, sand, gravel, and soil to automatically slide down and gather at the first slag outlet 41, thereby automatically collecting them.

[0049] Further, if Figure 3 As shown, the collection unit also includes a baffle, a collection trough, and a drive member. One end of the baffle 42 is rotatably mounted on the sidewall of the cavity via a rotating member. The baffle 42 can open or close the first slag discharge port 41. A collection trough 43 is connected to the bottom of the tank body 10 and is located below the first slag discharge port 41. The collection trough 43 is provided corresponding to the first slag discharge port 41 and is used to collect coal slag discharged from the first slag discharge port 41. The drive member is drivingly connected to the baffle 42 and can drive the baffle 42 to close the first slag discharge port 41.

[0050] In this embodiment, the collection part includes a baffle 42, a collection trough 43 and a driving member 44. The baffle 42 is a rotatable structure, one end of which is connected to the side wall of the cavity through a rotating member, and the other end of the baffle 42 is a free end, forming a movable door. The size and shape of the baffle 42 should ensure that it can completely close the first slag discharge port 41 to prevent accidental outflow of water under normal working conditions. The baffle 42 is provided with a driving member on the side away from the second cavity. The driving member 44 is a key component for controlling the opening and closing of the baffle 42. When the coal slag accumulates to a certain extent, the baffle 42 will be automatically pushed open, so that the coal slag can fall from the first slag discharge port 41 into the collection trough 43. The collection trough 43 is located at the bottom of the pool body 10, directly below the first slag discharge port 41, and connected to the bottom of the pool body 10. The design of the collection trough 43 should take into account the volume, shape and convenience of coal slag discharge, so as to facilitate the centralized collection and subsequent treatment of coal slag. As the sludge is discharged, when the accumulated sludge amount is insufficient to push the baffle 42 , the driving member gradually returns to its original position, thereby closing the first slag discharge port 41 .

[0051] Specifically, the material of the collecting trough 43 should have good wear resistance and corrosion resistance to adapt to the use conditions of the mine environment.

[0052] Furthermore, the driving member 44 includes a support rod 441, a sleeve 442, a telescopic rod 443 and an elastic member. The support rod 441 is located above the first slag discharge port 41, and the support rod 441 includes a support section and a bending section arranged in sequence. Among them, the support section is arranged on the outer wall of the pool body 10 in the direction away from the pool body 10, and the distance between the bending section and the outer wall gradually increases towards the bottom of the pool body 10. One end of the sleeve 442 away from the telescopic rod 443 is hinged to the bending section, one end of the telescopic rod 443 is movably arranged in the sleeve 442, and the other end of the telescopic rod 443 is hinged to the baffle 42. The elastic member is arranged between the telescopic rod 443 and the sleeve 442, and the elastic member can provide a driving force for the telescopic rod 443 to move away from the sleeve 442, so as to drive the telescopic rod 443 to cooperate with the baffle 42 to close the first slag discharge port 41.

[0053] In this embodiment, the driving member 44 includes a support rod 441, a sleeve 442, a telescopic rod 443 and an elastic member. Among them, the support rod 441 is composed of a support section and a bending section. The support section is fixed on the outer wall of the pool body 10 to ensure the stability of the entire driving structure. The bending section forms a certain angle with the support section, and the distance between it and the outer wall of the pool body 10 gradually increases towards the bottom of the pool body 10, which helps the telescopic rod 443 and the baffle 42 to have a larger movement space and a smoother movement trajectory when opening and closing the first slag discharge port 41. The sleeve 442 is fixed on the bending section and is connected to the bending section by a hinge. One end of the telescopic rod 443 is movably arranged in the sleeve 442, and the other end is hinged to the baffle 42. Through the telescopic movement of the telescopic rod 443 in the sleeve 442, the opening and closing of the baffle 42 can be realized, thereby controlling the opening state of the first slag discharge port 41. An elastic member, such as a spring, is provided between the telescopic rod 443 and the sleeve 442 to provide a driving force for the telescopic rod 443 to move away from the sleeve 442. This allows the telescopic rod 443 to be pushed by the elastic member when there is no external power input, automatically pushing the baffle 42 to cooperate with the first slag discharge port 41 to close the slag discharge port. When the accumulation of small particles of coal slag, sand, gravel, and soil is sufficient, the telescopic rod 443 will be driven to contract in the sleeve 442, thereby opening the baffle 42 and completing the discharge of sludge. After the cleaning is completed, the telescopic rod 443 returns to its original position under the action of the elastic member, closing the first slag discharge port 41, and completing a cleaning cycle. This reduces the labor intensity of manual labor, enhances the degree of automation and reliability of the entire mine automatic drainage device, and is easy to maintain and adapts to the use conditions in the mine environment.

[0054] like Figure 2 As shown, the liquid level sensor includes a float 32, a first contact piece 33, a second contact piece 34, and a guide assembly 35. The float 32 is located in the first chamber. The first contact piece 33 is fixed to the outer wall of the tank body 10, and the second contact piece 34 is movably arranged outside the tank body 10 and located below the first contact piece 33. The second contact piece 34 is arranged corresponding to the first contact piece 33 and is connected to the float 32. The float 32 drives the second contact piece 34 to move up and down. The float 32, the first contact piece 33, and the second contact piece 34 cooperate with each other to control the opening or closing of the water pump 31. The guide assembly 35 is used to guide the movement direction of the float 32 and the second contact piece 34, so that the float 32 and the second contact piece 34 move in the vertical direction.

[0055] In this embodiment, the liquid level sensor includes a float 32, a first contact 33, a second contact 34, and a guide assembly 35. When the water level in the tank 10 rises, the float 32 rises with the liquid level, driving the connected second contact 34 upward. When the second contact 34 contacts the first contact 33, a signal is generated, which controls the water pump 31 to drain the water. As the water level drops, the float 32 and the second contact 34 descend due to gravity. When the second contact 34 separates from the first contact 33, the water pump 31 stops, thus achieving automatic control. The float 32 is located in the first chamber and connected to the guide assembly 35. The guide assembly 35 ensures that the movement paths of the float 32 and the second contact 34 remain vertical, preventing the float 32 from shifting due to floating objects or other external factors during water level fluctuations, which could affect the accuracy and stability of the liquid level sensor. The first contact 33 is fixed to the outer wall of the tank 10 and is electrically connected to an external controller. The second contact piece 34 is movably mounted on the exterior of the tank 10, below the first contact piece 33. It is connected to the float 32 via a guide assembly 35. Driven by the float 32, the second contact piece 34 can move vertically up and down. The relative position of the second contact piece 34 and the first contact piece 33 determines the trigger point of the liquid level sensor. By adjusting the initial position of the second contact piece 34, the liquid level triggering point can be adjusted. When the float 32 rises with the liquid level until it contacts the first contact piece 33, the contact between the contacts transmits a signal, triggering the external controller to automatically start the water pump 31.

[0056] Specifically, the float 32 should be made of a lightweight material with good buoyancy, such as foam plastic or a hollow metal ball. The size of the float 32 should be designed according to the size of the first chamber and the actual required sensitivity to ensure that it can accurately rise or fall with changes in the liquid level.

[0057] Furthermore, the guide assembly 35 includes a guide rod 351 and a limiting rod 352. The guide rod 351 has a first section, a connecting section, and a second section connected in sequence. The connecting section is located above the side wall of the pool body 10, the first section and the second section are arranged parallel to each other in the vertical direction, the first section is located inside the pool body 10, the first section passes through the first filter plate 21 and is partially located in the first chamber, the second section is located outside the pool body 10, the end of the first section away from the connecting section is connected to the float 32, and the end of the second section away from the connecting section is connected to the second contact piece 34. The limiting rod 352 passes through the side wall of the pool body 10 and is located below the connecting section. The extension direction of the limiting rod 352 is the same as the extension direction of the connecting section. The two ends of the limiting rod 352 have guide holes respectively. The two guide holes are arranged in a one-to-one correspondence with the first section and the second section. The first section is passed through one of the guide holes, and the second section is passed through the other guide hole.

[0058] In this embodiment, the guide assembly 35 includes a guide rod 351 and a limit rod 352. The guide rod 351 is composed of three parts, namely a first section, a connecting section and a second section, which are connected in sequence to form an integral guide rod 351. The connecting section is located above the side wall of the pool body 10 and serves to connect the first section and the second section so that they remain parallel in the vertical direction. The first section is located on the inner side of the pool body 10, and the part that passes through the first filter plate 21 is located in the first chamber and is directly connected to the float 32; the second section is located on the outer side of the pool body 10 and is connected to the second contact piece 34. The limit rod 352 is passed through the side wall of the pool body 10 and is located below the connecting section. Guide holes are provided at both ends of the limit rod 352 to ensure that the first section and the second section of the guide rod 351 can move up and down in a straight line, thereby ensuring the movement trajectory of the guide rod 351 and avoiding lateral displacement of the guide rod 351 when the water level changes, thereby ensuring the accuracy and stability of the liquid level sensor.

[0059] In other embodiments of the present application, a guide groove may be provided on the side wall of the pool body, and the guide rod and the guide groove may be used to cooperate to guide the float and the second contact piece.

[0060] Furthermore, the drainage component also includes a controller. The drainage component has multiple groups, and the multiple groups of drainage components are electrically connected to the controller. The drainage liquid levels of at least two groups of drainage components are different. The controller can independently drive the water pump 31 of any drainage component to open or close.

[0061] In this embodiment, multiple drainage assemblies are provided, all electrically connected to the controller. Each drainage assembly consists of a water pump 31, a drain pipe, and a liquid level sensor. Different drainage assemblies are designed to have different drainage levels. Specifically, the floats 32 in the liquid level sensors are positioned at different heights to sense changes in the liquid level within the tank 10. The controller receives signals from the liquid level sensors to determine the actual water level within the tank 10 and thereby determine the number of pumps 31 to activate. For example, liquid level sensor A is positioned at a lower position, while liquid level sensor B is positioned at a higher position. When the water level within the tank 10 rises to the level of liquid level sensor A, the controller activates the pump 31 connected to liquid level sensor A. As the water level rises further, reaching the level of liquid level sensor B, the controller activates an additional pump 31 connected to liquid level sensor B. This continues in this order. As the water level rises, more pumps 31 are activated to meet increasing drainage demands. Once the water level begins to drop, the pumps 31 are gradually deactivated in the reverse order to maintain the liquid level within the tank 10 within a safe range.

[0062] Specifically, the controller may be a microprocessor, a PLC or other forms of electronic control units.

[0063] like Figure 1As shown, the drainage device also has a second slag discharge port 45, which is arranged at the top of the side wall of the pool body 10, and the second slag discharge port 45 and the first slag discharge port 41 are located on the same side of the pool body 10. One end of the first filter plate 21 is arranged flush with the bottom of the second slag discharge port 45 in the vertical direction. The collecting part also includes a discharge pipe 46, which is arranged on the outside of the pool body 10. The discharge pipe 46 has an inlet and an outlet arranged in sequence along the vertical direction. The inlet is arranged corresponding to the second slag discharge port 45, and the outlet is connected to the collecting tank 43. The discharge pipe 46 is used to discharge the coal slag on the first filter plate 21.

[0064] Furthermore, the first filter plate 21 is tilted downward from a direction close to the second slag discharge port 45 , and the bottom plate is tilted downward from a direction close to the first slag discharge port 41 .

[0065] In this embodiment, a second slag discharge port 45 is provided at the top of the sidewall of the tank body 10, and is capable of receiving the coal slag filtered from the first filter plate 21 through the second slag discharge port 45. The second slag discharge port 45 is connected to the inlet of a discharge pipe 46, and the outlet of the discharge pipe 46 is connected to the collection trough 43, allowing the collection trough 43 to accurately collect the coal slag falling from the discharge pipe 46. The first filter plate 21 is tilted downward from the direction near the second slag discharge port 45, allowing the coal slag to roll to the second slag discharge port 45 due to gravity, thereby improving the collection accuracy.

[0066] Specifically, the second slag discharge port 45 can be set to a funnel shape or other shape that is convenient for collection, and can take on more coal slag at one time, preventing the coal slag from rolling to the outside, avoiding polluting the working environment and reducing cleaning efficiency.

[0069] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0070] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0071] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
