[0035] Embodiment one:

[0036] Referring to Figure 1 A dosing device for mine gushing water, comprising a medicine box 1, the dosing device for mine gushing water further comprises:

[0037] A dosing pipe 2 arranged in the medicine box 1, at least one suction hole 3 is arranged at the lower part of the dosing pipe 2, a discharge port 4 is arranged at the bottom of the dosing pipe 2, and a chute is arranged at the middle upper part of the dosing pipe 2;

[0038] A control plug 5 is arranged inside the dosing pipe 2 and is in sliding connection with the dosing pipe 2, and the control plug 5 is connected with a lifting rod 6 through the sliding slot;

[0039] The dosing pipe 2 is arranged inside the medicine box 1, the lifting rod 6 is used to drive the control plug 5 to lift in the dosing pipe 2, the pressure in the dosing pipe 2 changes, the suction hole 3 sucks the medicine water, and the discharge hole 4 discharges the medicine water.

[0040] Specifically, the medicine box 1 is a hexahedron box welded by stainless steel sheet, has high strength and strong corrosion resistance, a hole allowing the dosing pipe 2 to pass through is arranged at the bottom of the medicine box 1, the upper end of the dosing pipe 2 is fixed to the top of the medicine box 1 through welding or screwing, the control plug 5 is a soft rubber plug or a wooden plug, the outer diameter of the control plug 5 matches the inner diameter of the dosing pipe 2, the control plug 5 can slide up and down in the dosing pipe 2, a sliding slot is arranged at one side of the dosing pipe 2, the upper end of the control plug 5 is fixedly connected with a connecting rod 17, one end of the connecting rod 17 is fixedly connected with the lifting rod 6 through the sliding slot, when the lifting rod 6 lifts, the connecting rod 17 can be synchronously lifted in the sliding slot, then the connecting rod 17 drives the control plug 5 to synchronously lift in the dosing pipe 2, when the connecting rod 17 is lowered to the lowest position of the sliding slot, the control plug 5 blocks the suction hole 3, when the connecting rod 17 is raised, the suction hole 3 is opened one by one.

[0041] Before use, the lifting rod 6 is controlled to be raised, the lifting rod 6 drives the connecting rod 17 to rise in the sliding slot, the connecting rod 17 drives the control plug 5 to synchronously rise in the dosing pipe 2, then the lifting rod 6 is controlled to be lowered, so that the control plug 5 is synchronously lowered in the dosing pipe 2, and the air in the dosing pipe 2 is discharged through the discharge hole 4.

[0042] When in use, the medicine water is filled into the medicine box 1, the device is fixed in the mine water, the control plug 5 is raised, the suction hole 3 is opened, the pressure in the dosing pipe 2 is reduced, the medicine water flows from the medicine box 1 into the dosing pipe 2, when the control plug 5 is lowered, the dosing pipe 2 is pressurized, because the pressure in the medicine box 1 is greater than that in the dosing pipe 2, the medicine water is pushed into the mine water through the discharge hole 4, when the control plug 5 is lowered to the lowest position, the suction hole 3 is blocked by the control plug 5, and the medicine water is added through the above-mentioned reciprocating operation.

[0043] In the embodiment, the lifting rod 6 is arranged to drive the control plug 5 to lift in the dosing pipe 2, so that the suction hole 3 sucks the medicine water and the discharge hole 4 discharges the medicine water, thereby replacing the electric valve to automatically add or stop the medicine water, and the structure is simple and easy to maintain compared with the electric valve.

[0044] In addition, it should be noted that the movement of the lifting rod 6 can be achieved by a small electric push rod, a small air cylinder or an electric cylinder. Since these devices are of conventional structure, no detailed description will be given herein. Considering that the small electric push rod, the small air cylinder and the electric cylinder need additional energy supply and are relatively high in cost, another structure for achieving the movement of the lifting rod 6 is given in Embodiment Two.

[0045] Embodiment Two

[0046] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , based on Embodiment One, further and optionally, a reset spring 7 is connected to the upper end of the lifting rod 6, and an upper limit switch 8 is arranged on one side of the lifting rod 6.

[0047] Specifically, the upper limit switch 8 is installed in the medicine box 1, and one end thereof is a movable end. The upper end of the reset spring 7 is fixed to the upper end wall of the medicine box 1, and the lower end thereof is fixed to the upper end of the lifting rod 6. In this way, when the lifting rod 6 is lifted, the reset spring 7 is compressed, and when the reset spring 7 is relaxed, the lifting rod 6 is pushed to descend.

[0048] In this embodiment, the reset spring 7 is arranged to drive the lifting rod 6 to automatically descend.

[0049] Further and optionally, a first groove 9 allowing the upper limit switch 8 to be clamped therein is arranged on the outer wall of the lifting rod 6.

[0050] Specifically, the movable end of the upper limit switch 8 can move within a certain angle. When the lifting rod 6 is lifted, the position of the first groove 9 changes synchronously with the lifting rod 6. When the lifting rod 6 is lifted to the highest position, the first groove 9 is located at a position corresponding to the upper limit switch 8. At this time, the movable end of the upper limit switch 8 is clamped in the first groove 9, and the upper limit switch 8 clamped in the first groove 9 cannot move upward, so that the lifting rod 6 cannot continue to be lifted. At this time, the compressed reset spring 7 is relaxed and reset. The reset spring 7 exerts a downward force on the lifting rod 6. Since the upper limit switch 8 can move downward, the lifting rod 6 can move downward under the pushing of the reset spring 7.

[0051] In this embodiment, the upper limit switch 8 is arranged to limit the highest position of the lifting rod 6, so that the lifting rod 6 cannot continue to be lifted after reaching the highest position, thereby facilitating the relaxation and reset of the reset spring 7.

[0052] Further and optionally, a rotating shaft 10 is arranged below the lifting rod 6, an inner thread is arranged in the lifting rod 6, an outer thread is arranged on the upper portion of the rotating shaft 10, the upper end of the rotating shaft 10 is threadedly connected to the lifting rod 6, and the lower end of the rotating shaft 10 penetrates through the medicine box 1.

[0053] Specifically, since the upper end of the rotating shaft 10 is threadedly connected with the lifting rod 6, the rotation of the rotating shaft 10 can be converted into the linear motion of the lifting rod 6, that is, when the rotating shaft 10 rotates, the rotating shaft 10 can rotate to push the lifting rod 6 to move upward.

[0054] Further and optionally, a first rotation constraint switch 11 is connected below the upper limit switch 8, and a second groove 12 allowing the first rotation constraint switch 11 to be clamped is formed in the outer wall of the rotating shaft 10 from top to bottom.

[0055] Specifically, one end of the first rotation constraint switch 11 is connected with one end of the upper limit switch 8, so that when the upper limit switch 8 acts, the first rotation constraint switch 11 can be driven to act together; the second groove 12 is formed in the outer wall of the rotating shaft 10 from top to bottom to form a guide groove, and the cross section of the rotating shaft 10 is in the shape of an I-beam.

[0056] When the rotating shaft 10 pushes the lifting rod 6 to move upward to the highest position by rotating, the upper limit switch 8 is clamped into the first groove 9, and the upper limit switch 8 drives the first rotation constraint switch 11 to act together, so that the first rotation constraint switch 11 is clamped into the second groove 12, thereby limiting the rotation of the rotating shaft 10, so that the rotating shaft 10 stops rotating, and further so that the lifting rod 6 stops ascending after reaching the highest position.

[0057] In the embodiment, the first rotation constraint switch 11 and the second groove 12 are arranged, and the first rotation constraint switch 11 is clamped into the second groove 12, so that the rotating shaft 10 stops rotating.

[0058] Further and optionally, a mounting hole is formed in the bottom of the medicine box 1, and a bearing 14 is mounted in the mounting hole, the outer ring of the bearing 14 is fixed with the medicine box 1, and the inner ring of the bearing 14 is fixed with the rotating shaft 10.

[0059] In this way, when the rotating shaft 10 rotates, the inner ring of the bearing 14 can be driven to rotate synchronously, while the outer ring of the bearing 14 and the medicine box 1 remain stationary, so as to avoid the influence of the rotation of the rotating shaft 10 on the medicine box 1.

[0060] Further and optionally, a second rotation constraint switch 15 capable of being clamped into the second groove 12 is arranged on one side of the bearing 14, and the second rotation constraint switch 15 is connected with the first rotation constraint switch 11.

[0061] Specifically, since the second rotation constraint switch 15 is connected with the first rotation constraint switch 11, when the first rotation constraint switch 11 acts, the second rotation constraint switch 15 can be driven to act synchronously.

[0062] When the first rotation restriction switch 11 is clamped into the second groove 12, the first rotation restriction switch 11 drives the second rotation restriction switch 15 to move synchronously, so that the second rotation restriction switch 15 is clamped into the second groove 12, thereby further limiting the rotation of the rotating shaft 10.

[0063] During the falling process of the lifting rod 6, the upper limit switch 8 is reset, driving the first rotation restriction switch 11 and the second rotation restriction switch 15 to move synchronously, so as to release the rotation restriction of the rotating shaft 10, and the rotating shaft 10 resumes rotation.

[0064] Further and optionally, the lower end of the rotating shaft 10 is provided with a propeller blade 16.

[0065] Specifically, the rotating shaft 10 and the propeller blade 16 can be fixedly connected or detachably connected, the propeller blade 16 can rotate with the water flow, and the rotation of the propeller blade 16 can drive the rotating shaft 10 to rotate synchronously, thereby realizing the lifting of the lifting rod 6; the discharge port 4 is located upstream of the water flow, and after adding the medicine, the rotation of the propeller blade 16 can play a stirring role.

[0066] When the water flow speed is fast, the rotation speed of the propeller blade 16 will also increase, so that the lifting speed of the lifting rod 6 increases, thereby increasing the adding speed, and at this time, the stirring of the propeller blade 16 will also be more sufficient.

[0067] The working process of the embodiment is as follows: the propeller blade 16 rotates with the water flow, and the rotation of the propeller blade 16 drives the rotating shaft 10 to rotate synchronously, the rotating shaft 10 rotates to drive the lifting rod 6 to move upward, the lifting rod 6 drives the connecting rod 17 to ascend in the sliding groove, the connecting rod 17 drives the control plug 5 to ascend synchronously in the adding pipe 2, so that the pressure in the pipe decreases, and the medicine water is sucked into the pipe through the suction hole 3, when the lifting rod 6 ascends to the highest position, the upper limit switch 8 is clamped into the first groove 9, so that the lifting rod 6 cannot continue to ascend, and at the same time, the first rotation restriction switch 11 and the second rotation restriction switch 15 are clamped into the second groove 12, so that the rotating shaft 10 stops rotating, and then the compressed reset spring 7 is relaxed and reset, so that the lifting rod 6 moves downward, during the falling process of the lifting rod 6, the upper limit switch 8 is reset, driving the first rotation restriction switch 11 and the second rotation restriction switch 15 to move synchronously, so as to release the rotation restriction of the rotating shaft 10, and the rotating shaft 10 resumes rotation, during the descending process of the lifting rod 6, the control plug 5 descends synchronously, at this time, the space in the adding pipe 2 is compressed, and the medicine water is pushed into the mine water through the discharge port 4, so as to realize the addition of the medicine water.

[0068] In the embodiment, through the cooperation of the propeller blade 16 and the rotating shaft 10 and the lifting rod 6, and the cooperation of the upper limit switch 8, the first rotation restriction switch 11, the second rotation restriction switch 15, the first groove 9 and the second groove 12, the automatic addition of the medicine water and the automatic control of the adding amount and the adding frequency can be realized through the speed of the water flow, without the input of external energy or power.

[0069] In summary, the application sets the lifting rod 6 to drive the control bolt 5 to rise and fall in the dosing pipe 2, so that the pressure in the dosing pipe 2 changes, so that the suction hole 3 sucks the medicine water, and the discharge port 4 discharges the medicine water, so as to replace the electric valve to control the automatic addition or stop of the medicine water. Compared with the electric valve, the structure is simple and easy to maintain. The application cooperates the propeller blade 16, the rotating shaft 10 and the lifting rod 6, and cooperates the upper limit switch 8, the first rotation restriction switch 11, the second rotation restriction switch 15, the first groove 9 and the second groove 12, so that the automatic dosing of the medicine water can be realized by the speed of the water flow, and the automatic control of the dosing amount and the dosing frequency is realized without external energy or power input. The dosing device of the application is simple to install and manufacture, and is easy to popularize.

[0070] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the application and are not limiting.
