DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0027] like Figure 1 As shown, the underground equipment train liquid tank refueling system of the embodiment of the utility model includes a compressed air pipeline 1, an equipment train 2, a container 3 and a pneumatic diaphragm pump 4.

[0028] The compressed air pipeline 1 is laid along the lane and is used to provide air flow. Figure 1 As shown, the compressed air pipeline 1 can be an air inlet pipeline, and the compressed air pipeline 1 can be hung on the side of the tunnel and extend along the extension direction of the tunnel. When in use, fresh air can pass through the compressed air pipeline 1, so that fresh air can be supplied to the working surface, etc.

[0029] The equipment train 2 includes a liquid tank 5, which is used to store emulsion. Figure 1 As shown, the equipment train 2 may be located in the tunnel, and the liquid tank 5 may be disposed on the top of the equipment train 2. The container 3 may be an emulsion barrel, and the container 3 is used to store the emulsion.

[0030] The pneumatic diaphragm pump 4 is arranged adjacent to the liquid tank 5. For example, the pneumatic diaphragm pump 4 can be directly placed in the lane, and can move synchronously with the movement of the equipment train 2. The pneumatic diaphragm pump 4 has a liquid inlet, a liquid outlet and a gas interface. The liquid inlet is connected to the container 3, the liquid outlet is connected to the liquid tank 5, and the gas interface is connected to the compressed air pipeline 1. The pneumatic diaphragm pump 4 is used to pump the emulsion in the container 3 into the liquid tank 5 when the gas interface is fed with air.

[0031] When in use, the liquid inlet can be connected to the container 3 through a pipeline, and the liquid outlet can be connected to the liquid tank 5. When the emulsion needs to be replenished in the liquid tank 5, the compressed air pipeline 1 and the gas interface can be connected. Under the action of wind energy, the pneumatic diaphragm pump 4 can be operated, so that the emulsion in the container 3 can be pumped into the liquid tank 5, thereby replenishing the emulsion in the liquid tank 5.

[0032] In some embodiments, Figure 2 As shown, the underground equipment train tank refueling system includes a frame 12, which can be formed by splicing and welding pipes, etc. The top of the frame 12 can be a plane, and the pneumatic diaphragm pump 4 is fixed to the top of the frame 12. The pneumatic diaphragm pump 4 is connected to the container 3 through the liquid inlet pipe 7, and the liquid inlet pipe 7 is coiled and placed on the frame 12.

[0033] For example, the liquid inlet pipe 7 can be a rubber tube, and one end of the liquid inlet pipe 7 can be directly connected and fixed to the liquid inlet of the pneumatic diaphragm pump 4. Under normal conditions, the liquid inlet pipe 7 can be coiled and stored and directly placed on the frame 12. When the emulsion needs to be replenished, the liquid inlet pipe 7 can be unfolded and the inlet of the liquid inlet pipe 7 can be docked with the corresponding container 3, thereby facilitating the connection between the container 3 and the pneumatic diaphragm pump 4. The setting of the frame 12 facilitates the storage of the pneumatic diaphragm pump 4, the liquid inlet pipe 7, etc., and avoids the situation of messy stacking in the lane.

[0034] In some embodiments, the frame 12 includes a flat plate portion 13, a storage portion 14 and a plurality of legs 15, the pneumatic diaphragm pump 4 is installed on the top side of the flat plate portion 13, the storage portion 14 is arranged on the top side of the flat plate portion 13 and is spaced apart from the pneumatic diaphragm pump 4, the liquid inlet pipe 7 is stored in the storage portion 14, the plurality of legs 15 are all fixed under the flat plate portion 13, and the plurality of legs 15 are spaced apart along the circumference of the flat plate portion 13.

[0035] For example, Figure 2 As shown, the flat plate portion 13 can be on a rectangular frame, the storage portion 14 can be a box-shaped structure, and the storage portion 14 and the flat plate portion 13 can both be formed by welding square tubes, wherein the storage portion 14 is located above the flat plate portion 13 and can be located on the left side of the flat plate portion 13, and the pneumatic diaphragm pump 4 can be located on the right side of the storage portion 14.

[0036] There may be six legs 15, all of which may be square tube-shaped, and all of which may be welded and fixed below the flat plate 13 and extend in the up-down direction. When in use, the legs 15 may support the flat plate 13 to a certain height, thereby preventing the pneumatic diaphragm pump 4 from being submerged in water on the ground, thereby improving the protective effect.

[0037] In some embodiments, the storage portion 14 is surrounded by a plurality of plates, and the plates at the bottom of the storage portion 14 and at least a portion of the plates around the storage portion 14 are uniformly provided with through holes. Figure 2 As shown, the plate body can be a mesh plate, and the mesh holes on the mesh plate form through holes. The plate body can be welded by steel bars and pipes. The plate body on the side around the storage part 14 and the plate body on the bottom side of the storage part 14 can both be mesh plates, so that water, coal gangue, etc. can be discharged from the frame 12 through the through holes, which can also reduce the overall weight.

[0038] In some embodiments, Figure 1 As shown, the pneumatic diaphragm pump 4 is connected to the compressed air pipeline 1 through the gas pipeline 6, and the gas pipeline 6 is provided with a valve 9, which can be a solenoid valve, and the valve 9 is used to adjust the size of the air flow in the gas pipeline 6. Thus, the pumping speed of the pneumatic diaphragm pump 4 can be adjusted.

[0039] In some embodiments, Figure 1 As shown, a flow meter 10 is provided on the gas pipeline 6, and the flow meter 10 is used to monitor the flow rate of the gas flow in the gas pipeline 6. Since the gas flow in the compressed air pipeline 1 is unstable, the monitored flow value can indirectly feedback the size of the wind energy provided to the pneumatic diaphragm pump 4, and then the delivery of the emulsion to the liquid tank 5 can be intuitively understood.

[0040] In some embodiments, the use includes the following steps:

[0041] A1: Open valve 9 to allow the air flow in compressed air pipeline 1 to flow into pneumatic diaphragm pump 4 via gas pipeline 6. Figure 1 As shown, when the emulsion needs to be added to the liquid tank 5, the valve 9 can be directly opened, thereby facilitating the driving of the pneumatic diaphragm pump 4.

[0042] A2: The flow rate of the gas flow in the gas pipeline 6 is measured by the flow meter 10. The flow meter 10 can be located downstream of the valve 9. When in use, the flow value measured on the flow meter 10 can be directly read.

[0043] A3: If the monitored flow rate is greater than the set upper limit, the opening of the valve 9 is reduced; if the monitored flow rate is less than the set lower limit, the opening of the valve 9 is increased. Specifically, the set upper limit and the set lower limit may be the upper limit and the lower limit of the pneumatic diaphragm pump 4 during normal operation. Within this range, the pneumatic diaphragm pump 4 will not be overloaded, and the stability of the emulsion pumping is also guaranteed, thereby ensuring the delivery efficiency of the emulsion, and also playing a protective role for the pneumatic diaphragm pump 4.

[0044] In some embodiments, Figure 1As shown, the pneumatic diaphragm pump 4 is connected to the liquid tank 5 through a liquid outlet pipe 8 , and a pressure sensor 11 is provided on the liquid outlet pipe 8 . The pressure sensor 11 is used to monitor the pressure of the emulsion in the liquid outlet pipe 8 .

[0045] It should be noted that since the pneumatic diaphragm pump 4 is arranged adjacent to the liquid tank 5, the distance between the pneumatic diaphragm pump 4 and the liquid tank 5 can remain unchanged. Therefore, under normal circumstances, the liquid outlet pipe 8 can always be connected between the pneumatic diaphragm pump 4 and the liquid tank 5, thereby avoiding the situation in the prior art where the pipeline between the corresponding pump and the liquid tank 5 needs to be frequently disassembled, and avoiding the pulling and wear of the liquid outlet pipe 8. Since the distance between the pneumatic diaphragm pump 4 and the liquid tank 5 is relatively close, it is also beneficial to reduce the overall laying length of the pipeline. When in use, it can be directly connected to the liquid inlet pipe 7 and the container 3 in the corresponding connecting lane.

[0046] In some embodiments, the use includes the following steps:

[0047] B1: The pressure value of the emulsion in the liquid outlet pipe 8 is monitored by the pressure sensor 11 .

[0048] B2: If the pressure value is higher than the first threshold, the opening of the valve 9 is reduced; if the pressure value is lower than the second threshold, the opening of the valve 9 is increased, and the first threshold is greater than the second threshold. In this way, the delivery amount of the emulsion at the end of the liquid outlet pipe 8 can be detected. By observing the monitored pressure value, the situation where the emulsion cannot be completely delivered to the liquid tank 5 due to problems such as local leakage can be avoided, thereby ensuring the effectiveness of the emulsion delivery.

[0049] In some embodiments, a liquid level gauge is provided on the liquid tank 5, which is used to monitor the liquid level of the emulsion in the liquid tank 5, and when the liquid level information monitored by the liquid level gauge is not less than the set liquid level value, the connection between the compressed air pipeline 1 and the gas interface is cut off.

[0050] For example, the liquid level meter can be directly fixed on the liquid tank 5, and the liquid level meter can monitor the liquid level of the emulsion in the liquid tank 5 in real time. When the liquid level is lower than the corresponding value, the control system can directly control the valve 9 to open, thereby ensuring the timeliness and automation of the emulsion transported into the liquid tank 5. When the liquid level is higher than the corresponding value, the control system can close the valve 9, thereby cutting off the emulsion transported into the liquid tank 5, avoiding the need for special personnel to observe during the replenishment process, realizing the automation of the entire supply process, and reducing labor costs.

[0051] The underground equipment train tank refueling system of the utility model embodiment has the following beneficial effects:

[0052] 1. After rationally planning the position of the pneumatic diaphragm pump 4, the liquid outlet pipe 8 is directly laid to the emulsion tank 5 and is fixed for a long time, so it does not need to be recovered every time. The liquid inlet pipe 7 can basically correspond to the connecting lane in use every time it is refueled, and the emulsion can directly reach the vicinity of the pneumatic diaphragm pump 4 for operation.

[0053] 2. The use of the pneumatic diaphragm pump 4 is not affected by power outages and maintenance, and the refueling work can be carried out in a timely manner, facilitating the smooth progress of other work.

[0054] 3. The pneumatic diaphragm pump 4 is driven by wind, which will not cause electric shock accidents, thus improving the safety factor at work. The refueling liquid pipe reduces dragging, and the service life of the liquid pipe is significantly increased. The wind drive reduces the waste of power resources and reduces production costs.
