Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0038] Please see Figure 1-4 As shown, this embodiment is a multi-stage coal mine drainage device, including:

[0039] Main components: The main components include mounting bracket 11, fixing bracket 12 and drain pump 13;

[0040] The fixing frame 12 is located at the top of the mounting frame 11, and the drain pump 13 is installed inside the fixing frame 12;

[0041] The main component also includes a first connecting pipe 14 and a second connecting pipe 15:

[0042] The first connecting pipe 14 is fixedly connected to the front end of the drain pump 13, and the second connecting pipe 15 is fixedly connected to the top end of the drain pump 13.

[0043] The mounting bracket 12 provides space for the installation of the drainage pump 13, which is used to discharge water. The first connecting pipe 14 and the second connecting pipe 15 are used to connect the pipelines.

[0044] All of the above parts are existing technologies;

[0045] Components used: The components used include a connecting frame 21, a pulley 22, and a rotating rod 23;

[0046] The connecting frame 21 is fixedly connected to the bottom of the mounting frame 11, the rotating rod 23 is rotatably connected to the inner wall of the connecting frame 21, and the pulley 22 is fixedly connected to one end of the rotating rod 23;

[0047] The components also include a limiting shaft 24, a plug 25, and a through slot 26;

[0048] The limiting shaft 24 is fixedly connected to the other end of the rotating rod 23, the insertion rod 25 is fixedly connected to the bottom four corners of the fixing frame 12, and the through groove 26 is opened at the top of the mounting frame 11;

[0049] The connecting bracket 21 provides space for the rotating rod 23 to rotate, the limiting shaft 24 is used to open the slot, and both the slot and the through groove 26 are used to provide space for the insertion of the plug rod 25;

[0050] With the auxiliary cooperation between the insertion rod 25 and the limiting shaft 24, the device can be pushed and displaced during the process of raising and lowering the drainage pump 13;

[0051] Working principle: When the worker moves the drainage device;

[0052] First, when the drainage pump 13 is in the retractable state, it can assist the staff in directly pushing and displacing the device.

[0053] Next, when the drainage pump 13 descends and comes into contact with the top of the mounting bracket 11, the insert rods 25, which are fixed at the four corners of the bottom of the fixing bracket 12, can be inserted into the through groove 26 and into the slot opened in the limiting shaft 24. This can limit the limiting shaft 24, thereby preventing the rotating rod 23 from rotating inside the connecting bracket 21 and limiting the pulley 22.

[0054] This step can help staff quickly push and move the device.

[0055] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, also includes a protection component;

[0056] The protective components include a mounting frame 31, a protective shell 32, and a motor 33;

[0057] The fixed frame 31 is fixedly connected to the rear end of the mounting bracket 11, the protective shell 32 is fixedly connected to the top front end of the fixed frame 31, and the motor 33 is fixedly connected to the top end of the fixed frame 31.

[0058] The protective assembly also includes a threaded rod 34 and a screw block 35;

[0059] The threaded rod 34 is rotatably connected to the inside of the fixed frame 31, and the screw block 35 is fixedly connected to the rear end of the drain pump 13. The screw block 35 and the threaded rod 34 are threadedly connected.

[0060] The fixed frame 31 is used to provide space for the screw block 35 to rise and fall. The output shaft of the motor 33 is fixedly connected to the threaded rod 34 through the coupling. The threaded rod 34 and the screw block 35 are set on the same central axis. The protective shell 32 is used to provide space for the drainage pump 13 to be protected.

[0061] With the auxiliary cooperation between the threaded rod 34 and the screw block 35, the motor 33 can drive the drainage pump 13 to rise into the protective shell 32 for protection during operation.

[0062] Working principle: After the staff uses the drainage device;

[0063] First, the motor 33 is started to work, so that the output shaft of the motor 33 drives the threaded rod 34 to rotate inside the fixed frame 31 through the coupling;

[0064] Next, the screw block 35 can be made to rise vertically along the threaded trajectory outside the threaded rod 34, so that during the process of the screw block 35 rising vertically inside the fixed frame 31, the drain pump 13 is driven to rise and retract into the protective shell 32.

[0065] This step helps staff to retract and protect the drainage device, reducing damage caused by external factors.
