Description

Technical Field

[0001] This application relates to the field of underground drainage technology in mines, specifically to an automatic underground drainage control device for mines. Background Technology

[0002] During the mining process, the original geological structure is destroyed due to excavation, causing groundwater in the aquifer to flow into the roadway and working face, which can easily lead to underground water inrush accidents, resulting in the obstruction of underground production. In severe cases, it can endanger the lives of underground workers and cause huge economic losses to mining companies. Therefore, drainage is particularly important underground.

[0003] Currently, drainage in underground mine pump pits is primarily done manually, requiring dedicated personnel to monitor the process and remain on-site throughout. If multiple locations in the mine require drainage, even more personnel are needed, leading to a waste of human resources. This manual operation not only consumes significant manpower but is also labor-intensive and inefficient.

[0004] In view of this, it is necessary to design an automatic drainage control device for underground mines to solve the above problems. Utility Model Content

[0005] In view of the technical problems existing in the background art, this application provides an automatic drainage control device for underground mines.

The electrical contact device is located inside the cavity of the control box. The other end of the control rod is placed inside the electrical contact device. The length of the rope is less than the distance from the control rod to the reference water level at the water accumulation point.

[0009] In the technical solution of this application embodiment, by electrically connecting the control component and the drainage component, wherein the control switch in the control component controls the opening and closing state of the circuit by detecting the water level through a float device, and thereby controls the state of the drainage device, the automated control of the well drainage is realized, which greatly reduces manual operation and improves the efficiency and safety of drainage.

[0011] In some embodiments, the other end of the control rod is placed within the space formed by the first rubber contact piece and the second rubber contact piece; when the control rod is in a horizontal position, the metal rod in the control rod is connected to the metal piece; when the other end of the control rod is tilted upward to a certain angle, the metal rod in the control rod is not connected to the metal piece.

[0012] In this embodiment, by placing the other end of the control rod within the space formed by rubber contact piece one and rubber contact piece two, the connection state between the metal rod and the metal piece can be controlled by the tilt angle of the control rod according to the change in water level, thereby realizing the automatic start and stop of the drainage component.

[0013] In some embodiments, the control lever includes a metal rod located within the cavity of the control box and an insulating rod penetrating a first wall of the control box and connected to the metal rod.

[0016] In some embodiments, the control circuit further includes a circuit consisting of the water pump, green light, and red light connected in parallel via electrical signals.

When button switch one is pressed, if the green light is on, it indicates that the water level at the water accumulation point is higher than the reference water level. The control switch is closed, putting the control circuit in the open state, and the water pump starts to operate to carry out drainage work. When the water level is lower than the reference water level, the control switch will be opened, the water pump will be turned off, and drainage will stop. This process is repeated to achieve automatic drainage of water accumulation in the well.

[0040] Current technologies for handling drainage in underground mine pumping stations primarily rely on manual operation, a process that consumes significant manpower and resources. Therefore, the rational design of equipment to automate underground mine drainage is of paramount importance.

[0041] To address the aforementioned technical problems, this application provides an automatic drainage control device for underground mines. This device connects the control components to the drainage components via electricity, and utilizes a linkage mechanism involving a float and circuit control to achieve the automated and efficient timely drainage of accumulated water in underground mines.

[0042] For ease of explanation, the following embodiments use an example of an automatic drainage control device for underground mines according to an embodiment of this application.

[0043] Please refer to Figure 2 The automatic drainage control device for underground mines provided in the application embodiment includes: a control component and a drainage component electrically connected to the control component;

[0044] The control assembly includes a control box 1, a control switch connected to the control box 1, and a control circuit 3 located inside the control box 1.

[0045] The control switch includes a control rod 21 penetrating the first wall of the control box 1, an electrical contact device connected to the second wall of the control box 1, and a float device 23 connected to one end of the control rod 21 via a rope 24. The electrical contact device is located inside the cavity of the control box 1; the other end of the control rod 21 is placed inside the electrical contact device; the length of the rope is less than (slightly less than) the reference water level line from the control rod 21 to the water accumulation point. By electrically connecting the control assembly and the drainage assembly, wherein the control switch in the control assembly controls the opening and closing state of the circuit 3 by detecting the water level through the float device 23, and thereby controls the state of the drainage device, automated control of downhole drainage is achieved, significantly reducing manual operation and improving drainage efficiency and safety.

[0046] Further, in this embodiment of the application, the second housing wall of the control box 1 includes an upper wall and a lower wall; the electrical connection contact device includes a first fixing rod 221 connected to the upper wall of the control box 1, a second fixing rod 222 connected to the lower wall of the control box 1, a first rubber contact piece 223 connected to the other end of the first fixing rod 221, a second rubber contact piece 224 connected to the other end of the second fixing rod 222, and a metal piece 225 embedded in the second rubber contact piece 224; the first rubber contact piece 223 is located directly above the second rubber contact piece 224; the first rubber contact piece 223 and the second rubber contact piece 224 are not connected.

[0047] Furthermore, in the embodiments of this application, such as Figure 5 As shown, the rubber contact sheet 223 and the rubber contact sheet 224 have the following structural shapes: one side is a cuboid with a groove; the grooves of the rubber contact sheet 223 and the rubber contact sheet 224 are directly opposite each other.

[0048] Further, in this embodiment, the other end of the control rod 21 is placed within the space formed by the groove of the first rubber contact piece 223 and the groove of the second rubber contact piece 224 (the height of the control rod 21 within the space formed by the groove of the first rubber contact piece 223 and the groove of the second rubber contact piece 224 (here, the height of the control rod 21 is not its length but its width) is less than the height of the space formed by the groove of the first rubber contact piece 223 and the groove of the second rubber contact piece 224); when the control rod 21 is in a horizontal position, the metal rod 211 in the control rod 21 is connected to the metal piece 225; when the other end of the control rod 21 is tilted upward to a certain angle, the metal rod 211 in the control rod 21 is not connected to the metal piece 225. By placing the other end of the control lever 21 within the space formed by the first rubber contact piece 223 and the second rubber contact piece 224, the connection state between the metal rod 211 and the metal piece 225 can be controlled by adjusting the tilt angle of the control lever 21 according to changes in water level, thereby achieving automatic start and stop of the drainage assembly. When the water level drops, the float device 23 descends, one end of the metal rod 211 in the control lever 21 tilts upward, and the metal rod 211 disconnects from the metal piece 225, which can immediately cut off the power supply 31, prevent the drainage assembly from running dry, save energy, and prevent equipment damage.

[0049] Furthermore, in this embodiment, the control rod 21 includes a metal rod 211 located within the cavity of the control box 1, and an insulating rod 212 penetrating the first wall of the control box 1 and connected to the metal rod 211; the insulating rod 212 is connected to the first wall of the control box 1 by a pin 5. This effectively prevents current leakage and ensures the safety of the operator; in addition, it protects the metal rod 211 from corrosion by the external environment and extends the service life of the control rod 21.

[0050] Furthermore, in the embodiments of this application, such as Figure 1 , Figure 4 , Figure 5 As shown, the control circuit 3 includes a circuit consisting of a power supply 31, a control switch, a push-button switch, and a water pump 41 connected in series via electrical signals.

[0051] Furthermore, in this embodiment of the application, the control circuit 3 further includes a circuit formed by the water pump 41, the green light 32, and the red light 33 connected in parallel by electrical signals.

[0052] Further, in this embodiment, the push-button switch includes a first push-button switch 34 and a second push-button switch 35; the positive terminal of the power supply 31 is electrically connected to the second push-button switch 35, the second push-button switch 35 is electrically connected to the second connection point 37 (i.e., metal piece 225) of the control switch, the first connection point 36 (i.e., metal rod 211 in the control lever 21) of the control switch is electrically connected to the first push-button switch 34, the first push-button switch 34 is electrically connected to the water pump 41, the water pump 41 is electrically connected to the negative terminal of the power supply 31, one end of the red light 33 is electrically connected to the fulcrum on the first wire, the other end of the red light 33 is electrically connected to the negative terminal of the power supply 31, one end of the green light 32 is electrically connected to the fulcrum on the second wire, and the other end of the green light 32 is electrically connected to the negative terminal of the power supply 31. When power is connected to 31 and button switch 2 35 is pressed, if red light 33 is lit, it indicates that power is connected normally. When button switch 1 34 is pressed, if green light 32 is lit, it indicates that the water level at the water accumulation point is higher than the reference water level. The control switch is closed, putting the control circuit 3 in the open state, and the water pump 41 starts to operate to drain water. When the water level is lower than the reference water level, the control switch will be opened, the water pump 41 will be turned off, and drainage will stop. This process is repeated to achieve automatic drainage of water accumulation in the well.

[0053] The drainage assembly includes a water pump 41 electrically connected to the control assembly and a water pipe 42 connected to the outlet of the water pump 41; the water pump 41 is connected to the ground via a rope 25 for easy lifting and lowering of the water pump 41.

[0054] Furthermore, in this embodiment of the application, the float device 23 includes a float bottle.

[0055] The principle of an automatic drainage control device for underground mines provided in the embodiments of this application will be explained below.

[0056] like Figures 1-5 As shown, when power supply 31 is turned on and button switch 2 35 is pressed, if red light 33 illuminates, it indicates that power supply 31 is normally connected. When button switch 1 34 is pressed, if green light 32 illuminates, it indicates that the water level at the mine's underground water accumulation point is higher than the reference water level. The metal rod 211 in control rod 21 then connects to the metal piece 225 (triggering the electrical connection contact device), closing the control switch and connecting the control circuit 3. The water pump 41 starts operating and drains water in a timely manner. When the water level at the mine's underground water accumulation point is lower than the reference water level, the float device 23 descends with the water level. At the same time, the control rod 21 is pulled by rope 1, causing the metal rod 211 in control rod 21 to tilt upwards. The metal rod 211 in control rod 21 then connects to the metal piece 225, disconnecting the control switch. The water pump 41 then shuts off, stopping the drainage. This process is repeated to achieve automatic drainage of the underground water accumulation point.

[0057] Please also refer to Figures 1 to 5 According to one or more embodiments of this application, the automatic drainage control device for underground mines provided by this application comprises a control component and a drainage component. The control switch in the control component detects the water level via a float device 23 and, in conjunction with the open / closed state of the metal piece 225 in the electrical contact device connected to the control rod 21, controls the opening and closing state of the control circuit 3, thereby controlling the automatic start and stop of the drainage device. This achieves automated control of underground drainage, significantly reducing manual operation and improving drainage efficiency and safety. The design of the control switch ensures accurate and reliable start and stop of the drainage component when the water level changes, reducing drainage problems or water-related accidents caused by equipment malfunctions. The automatic drainage control device for underground mines provided by this application can improve mine drainage efficiency while effectively preventing safety accidents caused by excessively high water levels, ensuring production safety, reducing manual intervention, and possessing significant economic and social benefits.
