Description

Technical Field

[0001] The present invention relates to the technical field of underground mining, and in particular to large-size filling body water filtering equipment and a method for unmanned aerial vehicle (UAV) towing pre-buried water filtering pipes. Background Art

[0002] The backfill mining method is a safer and green mining method that fills the solid waste generated during the mining process into the goaf directly or after processing, so as to control ground pressure activities and surface collapse, improve the recovery rate, and protect surface vegetation. At present, most mines in China require the use of backfill mining method. In some mines that mine along the strike, the "one-by-one mining" method is adopted, that is, the mining area is divided at a certain distance along the strike, and the mining is immediately filled as pillars after mining, and then the ore bodies reserved on both sides as pillars are mined.

[0003] There are still some deficiencies in the existing technology during the construction process:

[0004] 1. The implementation of existing mining methods requires the rapid solidification of the filling body. However, the filling tailings of some mines are relatively fine, even mixed with impurities such as soil and sulfide, and the size of the void area is large, which leads to slow water filtration and slow solidification of the filling body. In the subsequent mining, the filling body falls off, resulting in an increase in the depletion rate, which seriously affects the subsequent mining of the ore body;

[0005] 2. During the construction process, workers need to work in the goaf area, which is prone to collapse accidents and poses a risk of accidents.

[0006] In response to the above problems, the present invention document proposes a large-size filling body water filtering device and method for using an unmanned aerial vehicle to tow a pre-buried water filtering pipe. Summary of the invention

[0023] In the present application, the method for using the large-size filling body water filtering device of the pre-buried water filtering pipe towed by the drone comprises the following steps:

[0024] S1. Drone traction and fixation: The drone uses a thin rope to pull the water filter pipe, extending from each access road in the mining area to the goaf area, and crosses to the top connecting road. In the connecting road, one end of the water filter pipe is fixed by fixing equipment. At the same time, retaining walls are built in each access road to ensure the stability of the water filter pipe. This method avoids direct exposure of personnel to the goaf area and ensures personnel safety;

[0025] S2. Clamping and preliminary fixation: When the drone pulls the water filter pipe through the bottom clamp plate and the top clamp block, the water filter pipe is released to fall into the arc groove of the bottom clamp plate.

The top clamp block moves downward under its own gravity and magnetic attraction, and clamps the water filter pipe together with the bottom clamp plate.

[0026] S3. Enhanced clamping stability: When the top clamping block moves downward, its T-shaped slider cooperates with the T-shaped slot of the bottom clamping plate to increase stability.

[0027] S4, repeating the operation and linkage mechanism: repeating the above steps to complete the clamping of multiple filter pipes. When the filter pipe on the far right is clamped, the clamping block on its top triggers the linkage mechanism to release the limit of the movable seat, so that the guide frame can be inserted into the filter pipe;

[0028] S5, automatic water pumping and filtering: the driving motor releases the water pump hose, which enters the water filter pipe under the guidance of the guide frame. The water in the water filter pipe is pumped out by the cooperation of the water pump and the hose, which increases the water filtering rate and reduces the solidification time. The whole process does not require manual operation, ensuring personnel safety.

[0029] S6. Supplement to enhance clamping stability: The movable seat moves toward the bottom clamping plate under the tension of the tension spring. Through the action of a series of mechanical structures, the clamping plate is clamped into the slot, further ensuring the stable clamping of the filter pipe by the top clamping block and the bottom clamping plate.

At this time, the movable seat 25 moves toward the direction of the bottom clamping plate 6 under the tension of the tension spring 42, and the guide frame 29 can be inserted into the corresponding water filter pipe 9, which is convenient for inserting the water suction hose 28 into the water filter pipe 9 to pump water later.

[0061] Example 2

[0062] refer to Fig.11, based on the improvement of Example 1: one side of the cross beam 8 is slidably connected with a plurality of vertical plates 43 through a cross plate, and a push block 44 is fixed to the bottom end of each of the plurality of vertical plates 43, and a slope 45 is provided on one side of the push block 44, and the slope 45 cooperates with the limit rod 41 to drive the push block 44 to move upward, and a step surface 46 is provided at the bottom of the push block 44, and the step surface 46 cooperates with the limit rod 41 to limit the push block 44, and a slot 49 is provided on one side of each of the plurality of vertical rods 14, and a card plate 48 engaged with the card slot 49 is slidably connected to the top of the cross beam 8, and the card plate 48, The clamping groove 49 is used to limit the vertical rod 14. One side of the vertical plate 43 is rotatably connected to the second connecting rod 47, and the top of the second connecting rod 47 is rotatably connected to the clamping plate 48, which is used to drive the clamping plate 48 to move; the movable seat 25 moves toward the direction of the bottom clamping plate 6 under the tension of the tension spring 42, and the cooperation between the limiting rod 41 and the inclined surface 45 pushes the vertical plate 43 to move upward. The vertical plate 43 pushes the clamping plate 48 to move through the second connecting rod 47, and the clamping plate 48 just fits into the clamping groove 49 to clamp the vertical rod 14, further ensuring the stability of the top clamping block 13 and the bottom clamping plate 6 in clamping the water filter pipe 9.

[0063] The method for using the large-size filling body water filtering device of the pre-buried water filtering pipe towed by the drone comprises the following steps:

[0064] S1. The drone is connected to the filter pipe 9 by pulling a thin rope, extending from each mining access 5 in the mining area to the goaf 1, and then crossing the goaf 1 from bottom to top, and is pulled to the connecting roads 2 on both sides of the top of the goaf 1 according to the principle of proximity, and then one end of the filter pipe 9 is fixed in the connecting road 2 by a fixing device, and then a filling retaining wall with a reserved filter pipe 9 is constructed in each mining access 5. Due to the use of drone traction, the staff does not need to be exposed to the goaf 1, ensuring the personal safety of the staff; during filling, the pre-buried filter pipe 9 begins to play a role, effectively improving the water filtration rate of the filling body, reducing the solidification time of the filling body, and reducing the impact on subsequent mining;

[0065] S2. When the drone pulls the water filter pipe 9 through between the bottom clamp plate 6 and the top clamp block 13, the drone slowly lowers the water filter pipe 9, and the water filter pipe 9 is located in the arc groove on the leftmost side of the bottom clamp plate 6. The water filter pipe 9 pushes the two arc blocks 20 to both sides, and the first spring 21 is compressed. The arc block 20 drives the support rod 22 to move, and releases the support of the support rod 22 on the top clamp block 13. Since the magnetic attraction of the first magnet 15 on the top clamp block 13 is slightly smaller than the gravity of the top clamp block 13, the friction tension between the support rod 22 and the top clamp block 13 is small, so the water filter pipe 9 can push the arc block 20 and the support rod 22 to move, and then the top clamp block 13 moves downward under the action of its own gravity, and the magnetic attraction between the second magnet 18 and the bottom clamp plate 6 can firmly adsorb the top clamp block 13 on the bottom clamp plate 6, so the bottom clamp plate 6 and the top clamp block 13 can initially clamp the water filter pipe 9;

[0066] S3. In addition, when the top clamping block 13 moves downward, the T-shaped slider 23 just cooperates with the T-shaped groove 17, which can limit the top clamping block 13 to a certain extent. In addition, the rotating ring 10 on the outer wall of the water filter pipe 9 is located on the side of the bottom clamping plate 6 and the top clamping block 13 away from the goaf 1. The bottom clamping plate 6 and the top clamping block 13 can further block the water filter pipe 9 through the rotating ring 10 to prevent the water filter pipe 9 from falling back into the goaf 1. When the water filter pipe 9 slides toward the goaf 1 under the action of gravity, the wedge block 11 can be inserted into the wedge groove 16. Through the cooperation of the wedge block 11 and the wedge groove 16, a downward pulling force can be applied to the top clamping block 13, thereby increasing the clamping force of the top clamping block 13 on the water filter pipe 9;

[0067] S4, repeating steps S1, S2 and S3, can complete the clamping of multiple water filter tubes 9, and the clamping of multiple water filter tubes 9 is arranged from left to right in the groove at the top of the bottom clamping plate 6. When the groove on the far right completes the clamping of the water filter tube 9, the top block 33 on one side of the top clamping block 13 on the far right pushes the sliding block 32 and the lifting plate 30 to move downward during the downward movement. The lifting plate 30 pushes the sliding push rod 35 to move through the first connecting rod 34. The sliding push rod 35 passes through the trapezoidal groove 39, and the cooperation between the sliding push rod 35 and the trapezoidal groove 39 drives the pin rod 37 to move downward. The pin rod 37 releases the limit on the movable seat 25. At this time, the movable seat 25 moves toward the direction of the bottom clamping plate 6 under the tension of the tension spring 42, and the guide frame 29 can be inserted into the corresponding water filter tube 9;

[0068] S5. The reeling of the water extraction hose 28 is released by driving the motor 27. One end of the water extraction hose 28 enters the water filter pipe 9 under the guidance of the guide frame 29. The water extraction hose 28 can be inserted into the water filter pipe 9. When the water in the filling body infiltrates into the water filter pipe 9 at a later stage, the water can be extracted by the cooperation of the water pump and the water extraction hose 28, which effectively improves the water filtration rate of the filling body, reduces the solidification time of the filling body, and reduces the impact on subsequent mining. The pulling, fixing and pumping of the water filter pipe 9 do not require manual operation, so the staff does not need to be exposed to the goaf 1, ensuring the personal safety of the staff;

[0069] S6. The movable seat 25 moves toward the bottom clamping plate 6 under the pulling force of the tension spring 42. The cooperation between the limit rod 41 and the inclined surface 45 pushes the vertical plate 43 to move upward. The vertical plate 43 pushes the clamping plate 48 to move through the second connecting rod 47. The clamping plate 48 just fits into the clamping groove 49 to clamp the vertical rod 14, further ensuring the stability of the top clamping block 13 and the bottom clamping plate 6 clamping the water filter pipe 9.

[0070] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 27 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selection according to their needs or convenience.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
