[0025] The following is combined with Figure 1-6 The utility model is further described.

[0026] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: an electromechanical device for automatic drainage in coal mines.

[0027] The specific technical solution includes a chassis 1, the top of which is fixedly connected with a lifting ring for easy lifting, and support legs 3 are fixedly connected to the bottom of the chassis 1 on all sides, the outer sleeve of the support leg 3 is provided with a lifting sleeve 4, the outer side of the lifting sleeve 4 is fixedly connected with a fixing plate 5, and a threaded rod 6 is threadedly connected in the fixing plate 5, and the threaded rod 6 is rotatably connected to the bottom of the chassis 1. Such an arrangement makes it convenient to rotate the threaded rod 6 to adjust and control the height of the lifting sleeve 4 outside the support leg 3, thereby facilitating the adjustment of the height of the chassis 1. In addition, the top of the chassis 1 is detachably fixedly connected with a top cover, and a through hole is provided in the top cover for passing the water pipe of the submersible pump 8.

[0028] In a further design, a water inlet 2 is provided on the outside of the chassis 1, and a submersible pump 8 is detachably fixedly connected inside the chassis 1. The submersible pump 8 is used to pump water. A guide shell 7 is fixedly connected to the outside of the chassis 1, and the bottom of the guide shell 7 is an open structure.

[0029] Among them, one side of the guide shell 7 is set to be an opening, and a side plate 9 is provided at the opening. The outer part of the guide shell 7 is provided with a sleeve 10, and a positioning bolt 11 is threadedly connected in the sleeve 10. The sleeve 10 is sleeved on the outside of the guide shell 7, and then the side plate 9 is fixed by the positioning bolt 11. A guide plate 14 and a limit ring 19 are also fixedly connected in the guide shell 7. The adjustment plate 17 passes through and is slidably connected to the guide plate 14. The guide plate 14 is used for guiding, and the limit ring 19 is used to support the floating block 15.

[0030] Among them, a floating block 15 is provided in the guide shell 7, and the top of the floating block 15 is fixedly connected to a lifting shell 20, an adjusting plate 17 is provided in the lifting shell 20, and a plurality of slots 18 are provided outside the adjusting plate 17, and a through hole 21 is provided outside the lifting shell 20, and a magnet block 16 is inserted in the through hole 21, and an iron sheet is embedded in the slot 18. When adjusting, the magnet block 16 is pulled out to adjust the height of the plate 17. After completion, the magnet block 16 is inserted into the lifting shell 20 and the adjusting plate 17, and is located in the slot 18 to form adsorption and fixation.

[0031] In order to realize automatic driving, a monitoring driving component is also provided outside the guide shell 7.

At the same time, the laser ranging sensor 13 can detect the distance between the adjustment plate 17 and the top of the guide shell 7. As the water level rises, the adjustment plate 17 will also rise. If the set distance is reached, the controller will start the submersible pump 8 to pump the water away through the submersible pump 8. When it is lower than the set water level, the controller will turn off the submersible pump 8.

[0033] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:

Then, as the water level rises, the water can push the floating block 15 to drive the lifting shell 20 and the adjusting plate 17 to move upward. At the same time, the laser ranging sensor 13 can detect the distance between the adjusting plate 17 and the top of the guide shell 7. As the water level rises, the adjusting plate 17 will also rise. If the set distance is reached, the controller starts the submersible pump 8 to pump the water away through the submersible pump 8.

[0035] In addition, the height of the adjustment plate 17 can be adjusted and controlled according to different water level depths. Specifically, the positioning bolt 11 is turned so that it does not interfere with the side plate 9, and then the side plate 9 is removed to allow the lifting shell 20 and the adjustment plate 17 to leak out, and then the magnet block 16 is pulled out to pull the height of the adjustment plate 17. After completion, the magnet block 16 is inserted into the lifting shell 20 and the adjustment plate 17, located in the slot 18, to form adsorption and fixation.
