DETAILED DESCRIPTION

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example 1:

[0030] An automated drainage system for mines, such as Figures 1-4 As shown, the system includes a support platform 1 and a multi-stage pump 2. A winding frame 5 is installed on one side of the multi-stage pump 2, and an extension tube 6 is wound around the winding frame 5. A collection mechanism 8 is installed at the end of the extension tube 6. The collection mechanism 8 includes a float 801, and several support rods 803 are fixedly installed on the outside of the float 801. Universal wheels 804 are installed at the ends of the support rods 803. The float 801 is supported by any three sets of universal wheels 804. The support platform 1 provides a stable foundation platform for the equipment, ensuring the stable operation of the multi-stage pump 2 in complex mining environments and avoiding vibration. To address equipment misalignment issues caused by displacement, the coordinated design of the winding frame 5 and the extension pipe 6, driven by the first motor 7 to rotate the winding frame 5, enables automatic winding and unwinding of the extension pipe 6, significantly improving pipeline deployment efficiency and reducing manual operation intensity. The float 801 in the acquisition mechanism 8 contacts the surface of the sloping pit through three sets of universal wheels 804. Utilizing the rolling characteristics of the universal wheels 804, the float 801 can adapt to changes in the pit slope, avoiding the wear problem caused by direct friction between the traditional fixed float 801 and the pit wall, thus extending the service life of the equipment.

[0031] See Figure 3 , Figure 4 The support rod 803 and the caster wheel 804 are both made of plastic. The extension tube 6 passes through the float 801 and is fitted with a filter cover 802 at the end. Compared with metal materials, plastic has the characteristics of being lightweight and corrosion resistant, which can reduce the overall weight of the float 801 and reduce the drag force on the extension tube 6. At the same time, the extension tube 6 passes through the float 801 and is fitted with a filter cover 802 at the end. The filter cover 802 intercepts large particles of impurities in the water through its porous structure, preventing them from entering the multi-stage pump 2 and causing impeller wear or blockage, thus ensuring the long-term stable operation of the pump body.

[0032] Example 2:

[0033] See Figure 3 , Figure 4 A light panel 805 is installed on the extension pipe 6, above the float 801. A lighting lamp 806 is installed on the lower outer side of the light panel 805. The lighting lamp 806 can provide local lighting for the dim environment underground, help operators observe the position of the float 801 and the water flow status in real time, avoid the risk of misoperation or equipment collision due to poor visibility, provide users with more accurate information on the position of the float 801, and improve the accuracy of observation of the float 801.

[0034] See Figure 3 , Figure 4 Several warning lights 807 are installed above the light panel 805. The lighting lights 806 and warning lights 807 are electrically connected to the internal power supply through the controller. The warning lights 807 above the light panel 805 are connected to the power supply through the controller. When an abnormal water level, equipment failure or pipe blockage is detected, the warning lights 807 will automatically trigger a flashing or color-changing alarm, quickly transmitting fault signals and improving emergency response efficiency. The integrated setting of lighting and warning functions reduces the installation requirements of additional lighting equipment, optimizes the equipment space layout, and manages energy consumption in a unified manner through the controller, avoiding power waste and meeting the energy conservation and environmental protection requirements of mines.

[0035] See Figure 1 , Figure 2 The multistage pump 2 is connected to an inlet pipe 3 and a drain pipe 4 on its outer side. The inlet pipe 3 is connected to an extension pipe 6, and the drain pipe 4 is connected to an external sewage treatment device. The multistage pump 2 is connected to the extension pipe 6 through the inlet pipe 3 and to the external sewage treatment device through the drain pipe 4, forming a complete closed-loop drainage circulation system. The efficient flow guiding design of the inlet pipe 3 can reduce water flow resistance and ensure that the multistage pump 2 can achieve large flow drainage with low energy consumption. The connection between the drain pipe 4 and the sewage treatment device directly purifies the sewage, avoiding environmental pollution caused by the direct discharge of wastewater containing impurities, which complies with the environmental protection regulations for mines. At the same time, the modular connection method of the inlet pipe 3 and the extension pipe 6 simplifies the pipeline expansion or replacement process, supports flexible adjustment of the drainage path according to actual needs, and improves the system adaptability.

[0036] See Figure 1 , Figure 2 The multistage pump 2 has a second motor 9 installed at its power input end, and a first motor 7 is installed on one side of the winding frame 5 to drive the winding frame 5 to rotate. Both the first motor 7 and the second motor 9 are electrically connected to an external power source through a controller to realize the automated winding and unwinding control of the extension pipe 6. Operators can adjust the winding and unwinding speed and length through a remote controller to avoid the safety risks and inefficiencies of manual operation. At the same time, the second motor 9 provides a stable power input to the multistage pump 2. Combined with the controller's coordinated management of the two motors, such as start-stop timing and power matching, it ensures the synchronous coordination of the winding and unwinding of the extension pipe 6 and the operation of the water pump during drainage operations, preventing equipment damage caused by sudden changes in pipe tension.

[0037] See Figure 1 , Figure 2The corrugated pipe two-way expansion joint can absorb the axial expansion stress of the pipeline caused by the geological activity or temperature change of the mine tunnel, avoids the interface cracking or leakage problem caused by the rigid connection, meanwhile, the spherical universal hinge allows the water inlet pipe 3 to deflect slightly in the radial and angular directions, adapts to the multidirectional extrusion or distortion of the pipeline caused by the irregular terrain of the tunnel, significantly improves the deformation resistance of the pipeline system, in addition, the combined design of the corrugated pipe and the universal hinge simplifies the pipeline installation and calibration process, reduces the equipment debugging time caused by the construction error, meanwhile, reduces the maintenance frequency in long-term use, and comprehensively improves the reliability and economy of the drainage system.

[0038] The implementation principle of the embodiment is that the support table 1 is used as a basic bearing platform, a multistage pump 2 installed above the support table 1 is communicated with an extension pipe 6 through a water inlet pipe 3, the extension pipe 6 is wound on a winding frame 5 and is driven to be wound and unwound by a first motor 7, a floating ball 801 connected at the end of the extension pipe 6, and the floating ball 801 is adapted to slide along the surface of the inclined pit hole through a plastic support rod 803 and a universal wheel 804 outside the floating ball 801, so as to reduce the friction and improve the protection of the collecting mechanism 8.

[0039] The multistage pump 2 is driven by a second motor 9, and water is discharged to a sewage treatment device through a drainage pipe 4, and the corrugated pipe two-way expansion joint and the spherical universal hinge added on the water inlet pipe 3 can compensate the multidirectional stress of the pipeline caused by the change of the terrain, and avoid the structural damage.
