Description

Technical Field

[0001] This utility model relates to the field of geothermal utilization, specifically to a device for recovering heat energy from the inrush water of a mine geothermal system. Background Technology

[0002] Mine geothermal resources are an important renewable energy source, but existing mine water inflow heat recovery technologies have many shortcomings. Traditional systems typically rely on fixed submersible pumps and static heat exchange structures, which are difficult to adapt to fluctuations in mine water levels, resulting in low heat recovery efficiency. Furthermore, mine water often contains impurities, which can easily clog pipes and equipment, increasing maintenance costs; the fixed installation location of submersible pumps can lead to them running dry or sucking in sediment at low water levels, affecting equipment lifespan. Simultaneously, the existing devices lack reliable locking mechanisms for their lifting and adjusting functions, resulting in insufficient stability, and lack modular design, making maintenance difficult. These problems severely restrict the efficient utilization of mine geothermal resources.

[0003] Therefore, in order to solve the above-mentioned problems, a targeted water inrush heat energy recovery device for mine geothermal systems is proposed. Utility Model Content

[0004] This invention addresses the problems mentioned above by designing a heat energy recovery device for mine geothermal systems. This device can recover and utilize the heat energy of mine water inflow, and the submersible pump used for pumping can adjust its height according to the water level to adapt to applicable needs. Lowering the height of the submersible pump increases the water supply pressure, improves pumping efficiency, and meets greater applicable needs.

[0005] To achieve the above objectives, this utility model provides a water inrush heat energy recovery device for a mine geothermal system, comprising: a heat exchange well, a return water well, a roadway system, a submersible pump, and a lifting device. The heat exchange well and the return water well are connected below each other through the roadway system. Water flowing through the roadway system can absorb heat through heat transfer. The lifting device is installed in the heat exchange well, and the submersible pump is slidably connected to the lifting device.

[0006] In this way, the gushing water is pumped out of the heat exchange well by a submersible pump for use. The used water then enters the circulation system through the return water well, enters the roadway system to absorb heat from the mine again, and enters the heat exchange well. The submersible pump can be adjusted in position in the heat exchange well by a lifting device to adapt to changes in water level and water depth, thus meeting greater water supply needs.

[0007] Furthermore, the lifting device includes a support device and a drive device. The support device is fixedly connected inside the heat exchange well, the submersible pump is slidably connected to the support device, and the drive device is located on the ground and one end is connected to the submersible pump.

[0008] In this way, the support device provides a track for the movement of the submersible pump, and the drive device provides power for the movement.

[0009] Furthermore, the support device includes a support column and a slide rail. The bottom end of the support column is fixedly connected to the bottom of the heat exchange well, the slide rail is fixedly connected to the side of the support column, and the submersible pump is slidably connected to the slide rail.

[0010] Furthermore, the drive device includes: a winch, a pulley block, a lifting ring, and a wire rope. The winch is installed on the ground, the pulley block is fixedly connected to the side of the support device, the lifting ring is fixedly connected to the top of the submersible pump, and one end of the wire rope is connected to the winch and the other end is connected to the lifting ring.

[0011] Using the above method, when it is necessary to raise the submersible pump, start the winch to pull the submersible pump up.

[0012] Furthermore, the submersible pump includes a sliding connecting plate, which is fixedly connected to the submersible pump and slidably connected to the support device, and a notch is provided on the inner wall of the sliding connecting plate.

[0013] Furthermore, the lifting device also includes a locking device, and there are several locking devices, which are spaced apart inside the support device and engage with the notch.

[0014] Furthermore, the locking device includes: a drive motor, a lead screw mechanism, a slider, a connecting rod, and a locking pin. The drive motor is fixedly connected inside the support device. The output end of the drive motor is connected to the lead screw mechanism. The other end of the lead screw mechanism is connected to the inner wall of the support device. The slider is slidably connected to the lead screw mechanism. The connecting rod is movably connected to both sides of the slider. The locking pin is movably connected to the other end of the connecting rod. The locking pin passes through the support device and locks into the notch.

[0015] In this way, the support column has a hole that passes through the guide rail. When the winch moves the submersible pump to the set position, the drive motor drives the locking column to extend and retract through the screw mechanism. The locking column goes into the notch, and the auxiliary steel wire rope plays a role in fixing the submersible pump.

[0016] Furthermore, it also includes a filtration device, which is fixedly connected to the upper part of the return water well.

[0017] Furthermore, the filtration device includes: a guide rail, a filter plate, and a support platform. The guide rail and the support platform are both fixedly connected to the inner wall of the return water well. The support platform is located below the guide rail, and the filter plate is slidably connected to the guide rail and supported on the upper part of the support platform.

[0018] In this way, impurities mixed in with the return water can be filtered when passing through the filtration device, and the filter plate can be lifted out by the guide rail for cleaning.

[0019] In summary, this utility model has the following advantages and beneficial technical effects:

[0020] 1. The present invention provides a device for recovering heat energy from inrush water in a mine geothermal system, which can recover and utilize the heat energy from inrush water in the mine.
