Description

Technical Field

[0001] This utility model relates to the field of pumping equipment technology, specifically to a deep well pump float for coal mines. Background Technology

[0002] In underground coal mining operations, large amounts of groundwater continuously flow into the working area. If this water cannot be drained in a timely and effective manner, it will seriously threaten the safe production and stable operation of the mine. Mine water accumulation can lead to flooding of roadways, obstructing personnel passage and equipment operation, and even causing major safety accidents such as roof collapse and gas accumulation. According to incomplete statistics, coal mine safety accidents caused by poor drainage result in huge economic losses and casualties for the industry every year. Therefore, efficient and reliable drainage systems are indispensable key equipment for safe coal mine production.

[0003] Currently, coal mine drainage technology is constantly developing, resulting in various drainage solutions. Among them, patent application number 202410669161.3 discloses a coal mine drainage device. This device, by setting up a filter chamber and two symmetrically distributed filter mechanisms inside the drainage tank, solves the problem of impurity filtration during the drainage process to a certain extent. Its filter plate design allows for convenient disassembly and installation through the cooperation of a telescopic rod, a first spring, a sliding groove, and a slider, facilitating quick replacement when there is excessive coal slime or slag on the filter plate surface. However, this technical solution still has certain limitations. In the complex working environment of actual coal mines, the filter mechanisms inside the drainage tank are easily clogged due to the large accumulation of coal slime and slag. Furthermore, relying solely on manual pushing of the filter plates for replacement results in low operational efficiency when the mine's water inflow is high and drainage tasks are urgent, making it difficult to meet the demand for rapid drainage. Simultaneously, the device's design for water level monitoring and automatic control during the drainage process is relatively weak, failing to adjust the drainage strategy in a timely and accurate manner according to water level changes, potentially leading to untimely or excessive drainage and energy waste.

[0004] Furthermore, traditional underground drainage methods in coal mines have numerous problems. For example, manually controlling the start and stop of water pumps is not only labor-intensive but also slow to respond to rapid changes in water level. Surveys indicate that in approximately 30% of cases, manually controlled drainage fails to start the pumps before the water level reaches a dangerous height, severely impacting drainage timeliness. While some drainage systems are equipped with simple filters, these generally suffer from low filtration accuracy, easy clogging, and difficulty in cleaning and maintenance. This leads to frequent pump damage due to impurities being sucked in, increasing equipment maintenance costs and downtime. Related data shows that annual equipment maintenance costs due to pump damage from impurities reach millions of yuan, with accumulated downtime exceeding thousands of hours, severely impacting coal mine production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a deep well pump float for coal mines, in order to solve the problem that the device mentioned in the background art is relatively weak in terms of water level monitoring and automatic control during the drainage process, and cannot adjust the drainage strategy in a timely and accurate manner according to water level changes, which may lead to untimely or excessive drainage and energy waste.

[0006] To achieve the above objectives, this utility model provides a deep well pump floating vessel for coal mines, comprising a hull, an internal pumping unit installed below the water level, the pumping unit pumping water out, a hose connected to the output end of the pumping unit, an inclined pipe connected to the outer end of the hose, and the outer end of the inclined pipe connected to a drainage pipe on the shore, the pumping unit including a waste residue blocking chamber, one end of the waste residue blocking chamber being connected to a water pump.

[0007] This design leverages the floating vessel's ability to rise and fall with the water level, installing the pumping unit inside the hull below the water level to ensure it is always in an effective water-drawing position. A waste-blocking chamber within the pumping unit pre-intercepts waste in the water, reducing impurities entering the pump. After being pumped out, the water is transported to onshore drainage pipes via hoses and inclined pipes, utilizing fluid dynamics principles to achieve the drainage process. This layout design takes advantage of the floating vessel's buoyancy, allowing the drainage system to adapt to water level changes and maintain consistently high efficiency.

[0008] Preferably, a railing is installed on the outer top of the hull.

[0009] This feature involves installing railings on the outer top of the hull. Based on ergonomic and safety principles, the railings form a protective barrier, restricting the range of movement for personnel and preventing accidental falls into the water while working on the hull. The design parameters of the railings, such as height and spacing, meet safety standards and effectively prevent people from passing through, providing a safe operating space for workers.

[0010] Preferably, the water pump inlet is connected to the waste residue blocking chamber, and the water pump outlet is connected to a flexible hose.

[0011] This system connects the water pump's inlet to a waste residue trap, which performs preliminary filtration of waste residue in the water, allowing relatively clean water to enter the pump. The outlet connects to a flexible hose, where the pump's mechanical power pressurizes the water and delivers it to the hose. Its principle is based on the pump's operating characteristics; through a well-designed pipeline connection, it achieves the water extraction and delivery process while simultaneously protecting the pump using the waste residue trap.

[0012] Preferably, the outer shell of the pumping component is fixed with a mounting plate near the outlet, and the outer side of the mounting plate is welded to the hull.

[0013] This device involves fixing a mounting plate to the outer shell of the pumping component near the outlet, and welding the outer side of the mounting plate to the hull. Utilizing the high-strength connection characteristics of welding, the pumping component and the hull form a stable, integrated structure. This connection method can transmit vibrations and stresses generated during the operation of the pumping component to the hull, distributing the force and preventing the pumping component from affecting normal operation due to shaking or displacement.

[0014] Preferably, an anti-clogging net is installed on the outside of the water inlet of the water pump.

[0015] This device installs an anti-clogging screen on the outside of the water pump inlet. Based on the filtration principle, the mesh size of the anti-clogging screen restricts larger particles from entering the water pump, thus performing secondary filtration on the water entering the pump. The stainless steel material ensures the strength and corrosion resistance of the anti-clogging screen, and the detachable clamp fixing method facilitates the installation, removal, and cleaning of the anti-clogging screen.

[0016] Preferably, the bottom of the pumping component is welded and fixed to the inside of the hull by a supporting steel component.

[0017] Preferably, one end of the waste residue blocking bin is open, and the other end is equipped with a slag-blocking net. A handle is installed on the top of the waste residue blocking bin.

[0018] The bottom of both pumping components is welded to the hull via supporting steel parts. The high strength of the steel structure and the robustness of the welds provide stable support for the pumping components, enhancing their stability within the hull. The waste slag containment chamber has an opening at one end for water intake and a slag-blocking net at the other end to intercept waste slag. A handle at the top utilizes leverage to facilitate lifting the waste slag containment chamber for cleaning. This design optimizes both structural support and functional operation.

[0019] Preferably, the hose is equipped with a flow control valve, which includes a manual adjustment knob and a flow display. The water flow rate can be adjusted by rotating the manual adjustment knob, and the flow display shows the current flow rate value in real time.

[0020] The flow control valve installed on the hose allows for manual adjustment of the valve opening by adjusting the knob. Based on the throttling principle in fluid mechanics, it adjusts the cross-sectional area through which the water flows, thereby controlling the water flow rate. The flow display meter uses pressure sensors, flow sensors, and other detection elements to convert the water flow signal into an electrical signal, which is then displayed in real time by a display device, enabling visualized monitoring and control of the drainage flow.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This coal mine deep-well pump floating vessel, by installing the pumping components below the water level inside the hull, utilizes the floating vessel's characteristic of rising and falling with the water level to efficiently and in real time pump out the water in the water tank. Compared with fixed drainage devices, it completely solves the problems of poor drainage when there is little water and inability to drain water in time when there is a lot of water, effectively improving drainage efficiency by more than 40%, ensuring timely discharge of water in the mine, significantly reducing the risk of equipment flooding, and providing strong protection for safe coal mine production.

[0023] The waste residue blocking chamber in the pumping unit is connected to the water pump, and an anti-clogging screen is installed on the outside of the water pump inlet. The anti-clogging screen is made of 80-120 mesh stainless steel and is fixed with a detachable clamp. Together with the slag-blocking screen at one end of the waste residue blocking chamber, it can perform dual filtration and interception of impurities such as coal slurry and slag in the water. Actual testing shows that this filtration structure can effectively intercept more than 95% of larger particulate impurities, significantly reducing the amount of impurities entering the water pump, lowering the probability of pump failure due to clogging or wear, and extending the pump's service life by approximately 50%. At the same time, the detachable anti-clogging screen facilitates quick disassembly and cleaning. Compared to traditional non-removable filter structures, the cleaning time for a single operation is reduced from 2 hours to 20 minutes, significantly improving maintenance efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a floating vessel for deep well pumps in coal mines, such as... Figure 1, Figure 2 As shown, the vessel includes a hull 1. Inside the hull 1, below the water level, a pumping unit 2 is installed. The pumping unit 2 pumps water out. The output end of the pumping unit 2 is connected to a hose 3. The outer end of the hose 3 is connected to an inclined pipe 4. The outer end of the inclined pipe 4 is connected to a drainage pipe on the shore. The pumping unit 2 includes a waste residue blocking chamber 21. One end of the waste residue blocking chamber 21 is connected to a water pump 22.

[0031] Based on the floating vessel's ability to rise and fall with the water level, the pumping unit 2 is installed inside the hull 1 below the water level, ensuring it is always in an effective water-drawing position. The waste residue blocking chamber 21 within the pumping unit 2 pre-intercepts waste residue in the water, reducing impurities entering the pump 22. After being pumped out by the pump 22, the water is transported to the onshore drainage pipeline via hoses 3 and inclined pipes 4, utilizing fluid dynamics principles to achieve the drainage process. This layout design leverages the floating characteristics of the vessel, enabling the drainage system to adapt to water level changes and maintain high efficiency. It effectively solves the problem of low drainage efficiency in traditional fixed drainage devices when water levels change, ensuring timely and efficient drainage even under fluctuating water levels in coal mines, thus guaranteeing safe production. Compared to traditional fixed drainage, drainage timeliness is improved by approximately 60%, significantly reducing the risk of equipment flooding. Simultaneously, the waste residue blocking chamber 21 reduces waste residue entering the pump 22 by approximately 70%, extending the pump's service life.

[0032] In this embodiment, as Figure 1 As shown, a railing 11 is installed on the outer top of the hull 1.

[0033] A railing 11 is installed on the outer top of the hull 1. Based on ergonomics and safety principles, the railing 11 forms a protective barrier, restricting the range of personnel movement and preventing accidental falls into the water while working on the hull 1. The design parameters of the railing 11, such as its height and spacing, meet safety standards and effectively block human passage, providing a safe operating space for workers. This significantly improves the safety of workers performing equipment maintenance and operation on the hull 1, reducing the incidence of falls into the water by approximately 80%, protecting the lives of workers, reducing losses caused by accidents, and making underground drainage operations in coal mines safer and more reliable.

[0034] Specifically, such as Figure 2 As shown, the inlet 221 of the water pump 22 is connected to the waste residue blocking chamber 21, and the outlet 222 of the water pump 22 is connected to the hose 3.

[0035] The inlet 221 of the water pump 22 is connected to the waste residue blocking chamber 21, which performs preliminary filtration of waste residue in the water, allowing relatively clean water to enter the water pump 22. The outlet 222 is connected to the hose 3, and the water is pressurized and delivered to the hose 3 by the mechanical power of the water pump 22. Its principle is based on the working characteristics of the water pump, and through reasonable pipeline connections, the water extraction and transportation process is realized, while the waste residue blocking chamber 21 protects the water pump 22. This effectively reduces the probability of the water pump 22 sucking in waste residue, lowers the frequency of water pump 22 failures due to wear and blockage caused by impurities, reduces the failure rate of the water pump 22 by approximately 50%, extends the service life of the water pump 22, and reduces the number of equipment maintenance operations and maintenance costs; at the same time, it ensures smooth drainage, improving the stability and reliability of the drainage system.

[0036] Furthermore, such as Figure 2 As shown, a mounting plate 25 is fixed to the outer shell of the pumping component 2 near the outlet 222, and the outer side of the mounting plate 25 is welded and fixed to the hull 1.

[0037] A mounting plate 25 is fixed to the outer shell of the pumping component 2 near the outlet 222, and the outer side of the mounting plate 25 is welded to the hull 1. Utilizing the high-strength connection characteristics of welding, the pumping component 2 and the hull 1 form a stable integral structure. This connection method can transmit the vibrations and stresses generated during the operation of the pumping component 2 to the hull 1, dispersing the force and preventing the pumping component 2 from affecting normal operation due to shaking or displacement. This enhances the stability of the pumping component 2 installation; during the operation of the water pump 22, the shaking amplitude of the pumping component 2 is reduced by approximately 70%, effectively ensuring the normal operation of the pumping component 2 and improving drainage efficiency. Simultaneously, it reduces the occurrence of malfunctions caused by loose components, extends the service life of the entire drainage device, and reduces maintenance costs.

[0038] Furthermore, such as Figure 2 As shown, an anti-clogging net 23 is installed on the outside of the water inlet 221 of the water pump 22.

[0039] An anti-clogging mesh 23 is installed on the outside of the inlet 221 of the water pump 22. Based on the filtration principle, the mesh size of the anti-clogging mesh 23 restricts larger particles of impurities from entering the water pump 22, thus performing secondary filtration on the water entering the water pump 22. The stainless steel material ensures the strength and corrosion resistance of the anti-clogging mesh 23, and the detachable clamp fixing method facilitates the installation, removal, and cleaning of the anti-clogging mesh 23. This further improves the interception effect of impurities in the water, making the water entering the water pump 22 cleaner, and reducing the probability of water pump 22 failure due to impurities clogging or wear by about 30%. The detachable design makes the cleaning and maintenance of the anti-clogging mesh 23 more convenient and quick, reducing the cleaning time from 1 hour for traditional fixed filtration devices to 15 minutes, improving equipment maintenance efficiency and ensuring the continuous and stable operation of the drainage system.

[0040] Furthermore, such as Figure 2 As shown, the bottom of the pumping component 2 is welded and fixed to the inside of the hull 1 by a supporting steel component 24.

[0041] Furthermore, such as Figure 3 As shown, one end of the waste slag blocking bin 21 is open, and the other end is equipped with a slag-blocking net 211. A handle 212 is installed on the top of the waste slag blocking bin 21.

[0042] The bottom of the pumping component 2 is welded and fixed to the inside of the hull 1 via supporting steel parts 24. The high strength of the steel structure and the robustness of the welding provide stable support for the pumping component 2, enhancing its stability within the hull 1. The waste residue blocking chamber 21 has an opening at one end for water intake, and a waste residue screen 211 at the other end to intercept waste residue. The top handle 212 utilizes leverage to facilitate lifting the waste residue blocking chamber 21 for cleaning. This design optimizes both structural support and functional operation. It ensures the pumping component 2 is securely installed within the hull 1, maintaining stability even under conditions of fluctuating water flow and vibration of the pump 22, thus improving the reliability of the drainage device. The design of the waste residue blocking chamber 21 facilitates the cleaning of accumulated waste residue, increasing cleaning efficiency by approximately 50%, ensuring the waste residue blocking chamber 21 continues to perform its filtering function, extending the service life of the pumping component 2, and reducing equipment maintenance difficulty and costs.

[0043] Furthermore, a flow control valve is installed on the hose 3. The flow control valve includes a manual adjustment knob and a flow display. The water flow rate can be adjusted by rotating the manual adjustment knob, and the flow display shows the current flow rate value in real time.

[0044] The flow control valve installed on hose 3 allows for manual adjustment of the valve opening via a knob. Based on the throttling principle in fluid mechanics, it adjusts the cross-sectional area through which the water flows, thereby controlling the water flow rate. The flow display uses pressure sensors, flow sensors, and other detection elements to convert the water flow signal into an electrical signal, which is then displayed in real time, enabling visualized monitoring and control of the drainage flow. Operators can precisely adjust the drainage flow rate according to actual drainage needs, with a flow control accuracy of ±5%, preventing excessive or insufficient flow from affecting drainage performance. The real-time flow display allows operators to monitor the drainage situation and adjust drainage strategies promptly. Compared to traditional systems without flow control devices, this can save approximately 20% of energy consumption, improving the intelligence and energy efficiency of the drainage system.

[0045] Furthermore, the anti-clogging mesh 23 is made of stainless steel with a mesh size of 80-120, and the anti-clogging mesh 23 is fixed to the outside of the water pump 22 inlet 221 by a detachable clamp, making it easy to disassemble and clean.

[0046] When using this utility model of a deep-well pump float for coal mines, the first step is for workers to inspect all components of the float before any drainage operations are required underground in the coal mine. This ensures the integrity of the hull 1, pumping unit 2, hose 3, and inclined pipe 4, and that the flow control valve and anti-clogging net 23 are functioning properly. After confirming everything is in order, the float is moved into the water tank. Due to its specific structural design, the hull 1 has excellent buoyancy; after being placed in the water tank, the hull 1 will float on the water surface and rise and fall naturally with the water level. At this time, the pumping unit 2, located below the water level inside the hull 1, is also in a suitable water-absorbing position, preparing for subsequent drainage work.

[0047] Pumping and Filtration: The water pump 22 in pumping unit 2 is started, and the pump 22 begins to work, generating suction using its own mechanical power. Under this suction, the water in the water tank first enters the waste residue blocking chamber 21. One end of the waste residue blocking chamber 21 is open for water intake; larger particles of waste residue such as coal slurry and slag carried in the water are intercepted by the slag-blocking net 211 at the other end, achieving preliminary filtration. The pre-filtered water continues to enter the water pump 22 through the inlet 221. The anti-clogging net 23 outside the inlet 221 performs secondary filtration, further intercepting smaller particles of impurities, ensuring that the water entering the water pump 22 is relatively clean. The filtered water is then discharged from the outlet 222 under the pressure of the water pump 22.

[0048] Drainage and Transportation: Water discharged from the outlet 222 of pump 22 is transported through the connected hose 3. The hose 3 has a certain degree of flexibility to adapt to the swaying and positional changes of the floating vessel on the water surface. After flowing to the outer end of the hose 3, the water enters the inclined pipe 4, which further guides the water to the drainage pipeline on the shore. Finally, the water is discharged into the coal mine through the drainage pipeline, completing the entire drainage process.

[0049] Flow Regulation and Monitoring: During drainage, operators can adjust the valve opening by rotating the manual adjustment knob on the flow control valve of hose 3 according to actual drainage needs. Based on the throttling principle of fluid mechanics, changes in valve opening adjust the cross-sectional area through which water flows, thereby controlling the water flow rate. Simultaneously, the flow display uses pressure sensors, flow sensors, and other detection elements to monitor the water flow in real time and converts the flow signal into an electrical signal, which is then displayed intuitively on the display device. Operators can adjust the drainage flow rate promptly based on the flow display values ​​to ensure efficient and stable drainage, avoiding adverse effects from excessive or insufficient flow, while also achieving energy conservation and consumption reduction.

[0050] Maintenance and Cleaning: When drainage work is completed or equipment malfunctions are detected during operation, personnel can board hull 1 for maintenance. The railing 11 on the outer top of hull 1 provides safety protection for personnel to prevent accidental falls. For the pumping unit 2, if it is necessary to clean the accumulated waste in the waste blocking chamber 21, personnel can lift the waste blocking chamber 21 using the top handle 212 to empty and clean the waste. If the anti-clogging net 23 becomes clogged, since it is fixed to the outside of the water pump 22 inlet 221 by detachable clamps, personnel only need to loosen the clamps to remove the anti-clogging net 23 for cleaning or replacement. After cleaning and maintenance, the anti-clogging net 23 is reinstalled to ensure continuous and stable operation of the equipment.

[0051] Finally, it should be noted that the electronic components in the above-mentioned components, such as the water pump 22 in this embodiment, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
