Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining equipment, specifically a floating drainage platform. Background Technology
[0002] Due to its geographical location, the open-pit mine concentrates both rainwater and groundwater. Water storage tanks are constructed based on the groundwater outflow points, with submersible pumps pumping water out in stages. The drainage system involves placing the pumps in simple steel frames submerged in the water. Because the incoming surface water contains a large amount of silt, the silt accumulates around the pumps over time, causing them to collapse during drainage, clogging the pump inlets, jamming the impellers, and damaging the equipment. Furthermore, the large amount of silt accelerates wear and tear on equipment and pipes. A significant amount of silt is discharged into the upstream pumping station's storage tank, reducing its capacity, requiring annual dredging by the company. The aging of the pump cable seals causes them to lose their sealing function under high water levels and pressures, allowing water to enter the motor and cause damage. Subsequent maintenance is difficult, making retrieval and placement challenging and posing a serious safety hazard. To address these issues, water pumps were installed on simple floats. However, due to insufficient lighting at night or inclement weather affecting remote operation and observation, the water level dropped, causing the pump to bottom out and suck in a large amount of mud and sand. This resulted in impeller blockage, pump jamming, and pump cavitation, posing a significant safety hazard to the equipment.
[0003] Existing drainage platforms suffer from numerous problems in practical applications. Firstly, they lack precise water level monitoring and drainage control mechanisms. When water levels drop to extremely low levels, drainage cannot be stopped promptly, easily leading to pump dry running. This not only severely damages the pump equipment and increases maintenance costs but also affects the normal operation of the drainage system. Secondly, they struggle to quickly and effectively alert operators to abnormal water levels, failing to ensure remote operators can promptly grasp the on-site water level situation and delaying response. Furthermore, the installation method of submersible pumps and drainage pipes within the platform's pump compartment is not ideal, easily leading to installation difficulties and pump tilting, affecting drainage efficiency and equipment stability.
[0004] Therefore, there is an urgent need for a floating drainage platform with automatic drainage control, reliable alarm functions, and the ability to ensure the safe and stable operation of the equipment.
[0005] Therefore, based on its many years of experience in design, development and actual production in this related industry, the applicant has studied and improved the existing structure and its shortcomings, and provided a floating drainage platform for water surface, in order to achieve a more practical purpose. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] To address the shortcomings of existing technologies, this utility model provides a floating drainage platform that solves the problem of automatic drainage control. When the water level drops to a certain level (probe touches the bottom), drainage automatically stops to prevent damage to equipment such as dry running of the submersible pump. It also promptly notifies remote operators of abnormal water levels. Furthermore, it solves the problem of stopping alarms and automatically restoring the pump circuit when the water level rises to a certain level, allowing remote operators to start the pump for drainage as needed based on the water level. Finally, it solves the problem of insulating the sensors and alarm lights on the platform, avoiding safety issues such as electrical leakage caused by the platform's metal material.
[0008] Install the submersible pump and drain pipe properly to ensure they are installed smoothly into the underwater pump compartment and prevent the submersible pump from tilting.
[0009] (II) Technical Solution
[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: a floating drainage platform, comprising an above-water structure, an underwater structure, and a pool bottom; the above-water structure includes a platform, two floats, a warning alarm, and a control device; the underwater structure includes a pump chamber for housing a water pump and a probe.
[0011] The pontoons are two parallel, sealed cylindrical steel pontoons that are fixedly welded to the bottom of the platform at certain intervals to provide buoyancy for the platform to float on the water surface; the platform is made into a C-shape with an opening on one side parallel to the axial direction of the two pontoons.
[0012] The platform frame is made of channel steel, with steel plates laid flat. The pump compartment is suspended and welded under the C-shaped platform. The opening of the pump compartment column is aligned with the opening of the platform to accommodate the submersible pump and drainage pipe, providing installation space for them.
[0013] The platform is surrounded by a steel welded fence, which is movably connected to one end of a connecting rod via pins. The connecting rod can move in a circular motion through the connection point, and the other end of the connecting rod is fixedly connected to a sensor. The middle part of the connecting rod is also movably connected to the top of the probe rod via pins, ensuring that the two can rotate relative to each other. A sleeve is fixedly welded to the fence, and the probe rod is in the internal space of the sleeve, which restricts the probe rod's up and down movement, allowing it to move up and down in the vertical direction. When the water level in the pool drops, the drainage platform drops with the water level. When the bottom of the probe rod touches the bottom of the pool, the probe rod gradually pushes the connecting rod upward. Since the connecting rod, fence, and probe rod are all movably connected, the connecting rod will move in a circular motion around the connection point with the fence, thereby driving the sensor to work and transmitting the information on water level changes, realizing the monitoring and feedback of water level.
[0014] Preferably, an alarm light is installed on the fence, and the alarm light, sensor and other electrical components form a control circuit.
[0015] Preferably, the pump compartment is equipped with a water pump cable, a submersible pump, and a drain pipe; the water pump cable provides a power transmission channel for the submersible pump to ensure its normal operation; the submersible pump draws surface water and discharges it through the drain pipe to achieve the drainage function; the drain pipe serves as the channel for the submersible pump to drain water, transporting the surface water drawn by the submersible pump to a designated location.
[0016] Preferably, the drain pipe and water pump cable are installed on the submersible pump to form an integral component. In order not to hinder the smooth installation of the submersible pump and drain pipe into the underwater pump compartment, the platform and the pump compartment are left with a notch in the same direction. The assembled submersible pump with drain pipe and water pump cable is hoisted as a whole and placed into the pump compartment of the platform along the notch direction, and the drain pipe is placed and stabilized in the direction of the C-shaped notch.
[0017] Preferably, a lug is fixed above the submersible pump, and a safety pin is inserted inside the lug to prevent the submersible pump from tilting inside the pump compartment.
[0018] Preferably, the pump housing frame and bottom are made of steel.
[0019] Preferably, the probe is made of metal, and the total length of the underwater part of the probe exceeds the bottom of the pump compartment by 20cm-40cm to ensure a safe distance between the drainage platform and the bottom.
[0020] Preferably, there is surface water between the floating drainage platform and the bottom of the pool, the drainage platform floats on the surface of the surface water, and the submersible pump draws water from the surface water.
[0021] (III) Beneficial Effects
[0022] This utility model provides a floating drainage platform, which has the following advantages compared with the prior art: By adding anti-bottom-touch circuit protection and water level alarm device, the floating device not only overcomes the impact of silt in the temporary water storage pond on the water pump, making the water pump hoisting convenient, but also automatically disconnects the water pump circuit and triggers the alarm when the probe touches the bottom or the water level is too low, avoiding damage to the water pump and wear of the equipment pipeline by silt. The working principle and structure are simple and reliable, reducing the workload of operators and reducing the cost of dredging the water storage pond of the enterprise.
[0023] 1. Automatic Drainage Control: An automatic control mechanism consisting of a probe, connecting rod, and sensors automatically cuts off the submersible pump's power supply and stops drainage when the water level drops to the bottom. This effectively prevents damage to the submersible pump caused by dry pumping, extends its service life, and reduces equipment maintenance costs. It also reduces manual intervention and improves the intelligence and efficiency of drainage operations.
[0024] 2. Timely alarm function: When drainage is stopped, the sound and light alarm lights are activated, which allows remote operators to detect abnormal water levels in a timely manner so that they can take immediate countermeasures to avoid serious consequences caused by abnormal water levels.
[0025] 3. Ensure equipment safety: Ensure the insulation of electrical equipment such as sensors and alarm lights, effectively avoiding safety hazards such as leakage caused by the metal material of the platform, ensuring the personal safety of operators and the safe and stable operation of equipment, and reducing the probability of safety accidents.
[0026] 4. Reasonable equipment installation: The design of the installation method of submersible pumps and drainage pipes, such as leaving notches in the same direction on the platform and pump compartment for easy installation, and inserting safety pins into the lugs of the submersible pump to prevent tilting, makes the equipment installation more convenient and ensures the stability of the submersible pump after installation. This helps to improve drainage efficiency and reduce drainage failures caused by equipment installation problems. Attached Figure Description

[0030] 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.
[0031] like Figures 1-2 As shown, this utility model provides a technical solution: a floating drainage platform, including an above-water structure, an underwater structure, and a pool bottom 16. The above-water structure includes a platform 7, two floats 11, a warning alarm and control device; the underwater structure includes a pump chamber 12 for housing a water pump and a probe 6.
[0032] The pontoons 11 are two steel cylindrical sealed pontoons, which are parallel and fixedly welded to the bottom of the platform 7 at a certain interval to provide buoyancy for the platform 7 and make it float on the water surface; the platform 7 is made into a C-shape with an opening on one side parallel to the axial direction of the two pontoons 11 in the middle of the platform 7.
[0033] The frame of platform 7 is made of channel steel, and the steel plate is laid flat. The pump chamber 12 is suspended and welded under the C-shaped platform 7. The opening of the column surface of pump chamber 12 is in the same direction as the opening of platform 7, which accommodates submersible pump 13 and drainage pipe 14 and provides them with installation space.
[0034] The platform 7 is surrounded by a steel fence 4. The fence 4 is movably connected to one end of the connecting rod 3 by a pin. The connecting rod 3 can move in a circle through the connection point. The other end of the connecting rod 3 is fixedly connected to the sensor 2. The middle part of the connecting rod 3 is also movably connected to the top of the probe rod 6 by a pin to ensure that the two can rotate relative to each other. A sleeve 5 is fixedly welded on the fence 4. The probe rod 6 is in the internal space of the sleeve 5, which restricts the probe rod 6 to move up and down, so that it can move up and down in the vertical direction. When the water level in the pool drops, the drainage platform drops with the water level. When the bottom of the probe rod 6 touches the bottom of the pool 16, the probe rod 6 gradually pushes the connecting rod 3 upward. Since the connecting rod 3 is movably connected to the fence 4 and the probe rod 6, the connecting rod 3 will move in a circle with the connection point with the fence 4 as the center, thereby driving the sensor 2 to work and transmit the information of water level change, so as to realize the monitoring and feedback of water level.
[0035] An alarm light 1 is installed on fence 4. The alarm light 1, sensor 2, and other electrical components form a control circuit.
[0036] The pump compartment 12 is equipped with a water pump cable 8, a submersible pump 13 and a drain pipe 14; the water pump cable 8 provides a power transmission channel for the submersible pump 13 to ensure the normal operation of the submersible pump; the submersible pump 13 draws surface water and discharges it through the drain pipe to realize the drainage function; the drain pipe 14 serves as the drainage channel for the submersible pump to transport the surface water drawn by the submersible pump to a designated location.
[0037] The drain pipe 14 and the water pump cable 8 are installed on the submersible pump 13 to form an integral assembly. In order not to hinder the smooth installation of the submersible pump 13 and the drain pipe 14 into the underwater pump chamber 12, the platform 7 and the pump chamber 12 are left with notches in the same direction. The assembled submersible pump 13 with the drain pipe 14 and the water pump cable 8 is hoisted as a whole and placed into the pump chamber 12 of the platform 7 along the notch direction. The drain pipe 14 is then placed and stabilized in the C-shaped notch direction.
[0038] A lug 10 is fixed above the submersible pump, and a safety pin 9 is inserted inside to prevent the submersible pump 13 from tilting inside the pump chamber 12.
[0039] The pump compartment 12 frame and bottom are made of steel.
[0040] The probe rod 6 is made of metal, and the total length of the underwater part of the probe rod exceeds the bottom of the water pump chamber 12 by 20cm-40cm to ensure a safe distance between the drainage platform and the bottom.
[0041] There is surface water 15 between the floating drainage platform and the bottom of the pool 16. The drainage platform floats on the surface of the surface water 15, and the submersible pump 13 draws water from the surface water.
[0042] In Example 1, during operation, as the water level decreases during drainage, the probe rod moves upward along the direction of the sleeve after its lower end touches the bottom. The upper end of the probe rod, through a fulcrum connected to a connecting rod, lifts the connecting rod upward, causing it to rotate around a movable fixed point on the fence. The sensor fixed to the other end of the connecting rod moves upward in an arc. When the sensor reaches a certain angle, it sends a circuit break signal, cutting off the power to the submersible pump and stopping drainage. Simultaneously, an audible and visual alarm is activated, allowing remote operators to promptly detect abnormal water levels. As the surface water in the pool increases, the platform rises, the probe rod descends, causing the sensor to return to its original angle and activating the pump circuit. At this point, drainage operators can begin drainage operations as needed, depending on the water level. Simultaneously, the flashing alarm light circuit is disconnected, and the alarm light stops flashing.
[0043] The probe is made of metal, and its underwater length extends 20-40cm beyond the bottom of the pump compartment. Since the platform is entirely metal, proper insulation must be ensured when installing the sensors and alarm lights.
[0044] In summary, this floating device, by adding bottom-touch circuit protection and a water level alarm device, not only overcomes the impact of excessive silt in the temporary water storage pond on the water pump, making the water pump hoisting convenient, but also automatically disconnects the water pump circuit and triggers an alarm when the probe touches the bottom or the water level is too low, avoiding damage to the water pump and wear of the equipment and pipelines by silt. The working principle and structure are simple and reliable, reducing the workload of operators and reducing the cost of dredging the water storage pond for enterprises.
[0045] Automatic drainage control: Through an automatic control mechanism consisting of a probe, connecting rod, and sensor, the submersible pump power is automatically cut off and drainage stops when the water level drops to the bottom of the probe. This effectively avoids damage to the submersible pump caused by dry pumping, extends the pump's service life, reduces equipment maintenance costs, reduces manual intervention, and improves the intelligence level and efficiency of drainage operations.
[0046] Timely alarm function: When drainage is stopped, the sound and light alarm lights are activated, which allows remote operators to detect abnormal water levels in a timely manner so that they can take immediate countermeasures to avoid serious consequences caused by abnormal water levels and ensure the safety and stability of the production process.
[0047] Ensuring equipment safety: Ensuring the insulation of electrical equipment such as sensors and alarm lights effectively avoids safety hazards such as leakage caused by the metal material of the platform, protects the personal safety of operators and the safe and stable operation of equipment, and reduces the probability of safety accidents.
[0048] Reasonable equipment installation: The design of the installation method of submersible pumps and drainage pipes, such as leaving notches in the same direction on the platform and pump compartment for easy installation, and inserting safety pins into the lugs of the submersible pump to prevent tilting, makes the equipment installation more convenient and ensures the stability of the submersible pump after installation. This helps to improve drainage efficiency and reduce drainage failures caused by equipment installation problems.
