Description

Technical Field

[0001] The utility model relates to the technical field of mine drainage equipment, in particular to mine drainage automation equipment. Background Art

[0002] Mine drainage is an important measure to ensure mine safety and smooth production. In mines, water sources may come from groundwater, rainfall, production activities, etc. If these waters are not discharged in time, they will accumulate in the tunnels, affecting the safety of miners and production efficiency.

[0003] In order to ensure the safety of miners and production efficiency, drainage equipment is used. Commonly used equipment for mine drainage includes horizontal centrifugal pumps. According to the water inlet method of the pump, it can be divided into suction type and pressure type. Pump room and sedimentation tank are also common drainage facilities for storing and treating mine water.

[0004] When draining water, the pump equipment is set at the water accumulation location, and then the pipes are connected to pump out the accumulated water. Generally, several fixed water accumulation points are set up in the mine to guide the generated accumulated water to the corresponding location, and then discharged as a whole through the equipment.

[0005] However, when using it now, the user is required to open the drainage device regularly or manually, which is not only inconvenient to operate, but also easy to forget to open it or the water volume suddenly increases, so there are certain safety hazards;

[0006] At the same time, due to the complex composition of mine water, if the water level sensor is used directly, it is easy to damage the sensor, resulting in inaccurate detection and control, causing losses and inconvenience to users. Utility Model Content

DETAILED DESCRIPTION

[0037] 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 part of the embodiments of the present invention, not all of the embodiments. 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.

[0038] A mine drainage automation device includes a water pump 10. The water inlet end of the water pump 10 is provided with a water inlet pipe 20. The water pump 10 can use the common water pump equipment used in existing mine drainage equipment, connect to the existing controller and control structure, and use the existing method to connect and control.

[0039] In the examples of this application, please refer to Figure 1 and 2 A bottom sleeve 30 is fixed to the end of the water inlet pipe 20 away from the water pump 10. A plurality of grooves 31 are provided at the bottom of the bottom sleeve 30 and are connected to the water inlet pipe 20. When in use, the bottom sleeve 30 is placed at the position of mine drainage pumping, and the bottom of the bottom sleeve 30 is placed at the bottom of the water. Water can leak through the grooves 31 to avoid blockage.

[0040] A fixed rod 40 is fixed to the top of the bottom sleeve 30, and a connecting sleeve 50 is slidably connected to the outside of the fixed rod 40. Specifically, the fixed rod 40 includes a rod body 41 fixed to the top of the bottom sleeve 30, and a plurality of limiting holes 42 are opened inside the rod body 41. The connecting sleeve 50 includes a movable sleeve 51 sleeved on the outside of the rod body 41, and the movable sleeve 51 and the limiting hole 42 are movable through the limiting rod 52. Figure 2 As shown, when in use, the overall height can be adjusted according to the position of the limiting hole 42 into which the limiting rod 52 is inserted to meet different water level detection requirements.

[0041] Furthermore, a fixing ring 54 is fixed to the outer wall of the movable sleeve 51 through a plurality of connecting rods 53 arranged in a ring shape, and a detection structure 60 for detecting the water level is supported on the top of the fixing ring 54;

[0042] Specifically, in this embodiment, please refer to Figure 1 and 2 The detection structure 60 includes a sliding sleeve 61 that is slidably sleeved on the outside of the movable sleeve 51. There is a gap between the sliding sleeve 61 and the movable sleeve 51 to prevent the sliding sleeve 61 from getting stuck when sliding up and down. The bottom of the sliding sleeve 61 is fixedly sleeved with a fixed plate 62. The bottom of the fixed plate 62 is fixed with a floating plate 63. The floating plate 63 can be a floating plate body that absorbs existing materials, such as a foam board floating plate. The floating plate 63 is located at the top of the fixed ring 54. The top outside of the sliding sleeve 61 is fixedly sleeved with a collar 64. The top of the movable sleeve 51 is fixed with a connecting plate 65. The collar 64 and the connecting plate 65 are preferably annular. A contact sensor 66 is provided at the bottom of the connecting plate 65. The contact sensor 66 is electrically connected to the controller of the existing water pump 10. The contact sensor 66 is an existing sensor and is controlled using an existing method and program.

[0043] During use, the heights of the connecting sleeve 50 and the detection structure 60 are first determined according to the above embodiment as needed. Then, as the water level increases, when the floating plate 63 is contacted, the floating plate 63 is affected by the buoyancy and moves upward, which in turn drives the fixed plate 62, the sliding sleeve 61 and the collar 64 to move upward until they abut against the contact sensor 66. The contact sensor 66 senses a signal, which is then transmitted to the control device in an existing manner. The control device controls the water pump 10 to start in an existing manner to complete pumping. The operation is simple and can automatically pump water after reaching a certain water level, avoiding situations such as forgetting to start the pump, which brings convenience to the user.

[0044] The contact sensor 66 can be regarded as a switch and can use the simplest existing control program or structure.
