Description

Technical Field

[0001] This utility model relates to water treatment, and in particular to a floating platform for reoxygenation devices that improves the stability of reoxygenation devices in water. Background Technology

[0002] The reoxygenation device is a product used in the treatment of deep-water lakes and reservoirs. It works by blowing compressed air into an underwater pulse chamber. The accumulated air in the pulse chamber is suddenly released into a riser pipe, forming a pulsed bubble piston flow that accelerates upwards. This propels / drives the water at the bottom of the deep-water lake or reservoir upwards through the riser pipe until the pulsed bubbles burst out of the riser pipe outlet and diffuse radially to the surface layer. Simultaneously, this achieves reoxygenation of the upper water layer and vertical flow field circulation mixing between the upper and lower water layers. Meanwhile, the water in the pulse chamber, rich in supersaturated dissolved oxygen, flows back to the bottom of the deep-water lake or reservoir during the formation of the pulsed bubbles, achieving reoxygenation of the bottom water. Under the suction effect of the reoxygenation device, the dissolved oxygen in the bottom water of deep-water lakes and reservoirs is restored and increased, effectively controlling the release of phosphorus, nitrogen, organic matter, iron, manganese, etc., from sediments, while simultaneously reducing the levels of phosphorus, nitrogen, organic matter, iron, manganese, etc., in the water, thus achieving water purification.

[0003] Typically, reoxygenation devices need to be vertically inserted into the water, with the bottom of their riser pipe vertically positioned on the bottom and the upper part fixed to a floating hoisting platform. The buoyancy of the hoisting platform allows the reoxygenation device to float in the water. The hoisting platform is then fixed to the shore and the bottom by steel cables, and the reoxygenation device is connected to the ventilation pipe. However, in actual use, the steel cables connecting the hoisting platform can only ensure that the position of the hoisting platform does not shift significantly, but they do not significantly contribute to stability. When the water surface fluctuates greatly or the wind is strong, the reoxygenation device is prone to shaking, which not only affects water circulation but also easily causes the connection between the reoxygenation device and the ventilation pipe to detach, affecting water treatment and even causing equipment damage. Summary of the Invention

[0004] The present invention aims to solve the problem that the current reoxygenation device is installed on a floating hoisting platform, which has poor stability, affecting the water treatment effect and easily causing equipment damage. The present invention provides a floating hoisting platform for the reoxygenation device that improves the stability of the reoxygenation device in water.

[0005] This utility model discloses a floating platform for a reoxygenation device. The reoxygenation device is installed on the platform. The platform comprises floats, connecting steel cables, and a self-balancing device. Four floats are connected and fixed in a square shape. The reoxygenation device is vertically installed at the center of the square. The outer edges of the four floats are connected to fixed blocks on the shore and lake bottom via connecting steel cables. The self-balancing device is installed on the floats and connected to the power supply of the reoxygenation device. Wherein:

[0006] The self-balancing device includes a balancing frame, balancing paddles, and motors. The balancing frame is shaped like a cross and is horizontally installed near the center of the float. Four balancing paddles are installed vertically at equal intervals on the bottom edge of the float. Four motors are installed on the float, with one motor connected to each of the four ends of the balancing frame. The balancing paddles are connected to the motor shafts.

[0007] The balancing frame includes four sets of slide rails, which are perpendicular to each other. Each set of slide rails includes two parallel slide rods and a slider. The slider is mounted on the two slide rods and slides along them. The front section of each slide rod near the center of the balancing frame is an insulating section made of insulating material, and the rear section away from the center of the balancing frame is a conductive section made of conductive material. The slider is made of conductive material. The rear section of the slide rod is connected to the motor through a wire.

[0008] The rear end of the slide bar is tilted upwards, with the tilt angle not exceeding 5°.

[0009] The four ends of the balancing frame point to the four balancing paddles respectively.

[0010] When the hoisting platform tilts to one side due to water surface fluctuations or wind, the balance frame on the hoisting platform tilts synchronously with the platform. The slider on the downward tilting section of the balance frame slides towards the rear end of the slide rail on the same side under the influence of gravity. When the slider contacts the conductive section of the slide rod, the circuit of the slide rod, power supply, and motor is closed. The power supply powers the motor, and the motor drives the balance paddle to rotate through the shaft. The rotation of the balance paddle generates downward thrust, which is used to raise the float on that side, allowing the float to regain balance. When the float is rebalanced, because the rear end of the slide rod tilts upward, the slider slides towards the front end of the slide rod under the action of gravity. When the slider slides back to the insulating section of the slide rod, the circuit of the motor is disconnected, and the motor stops working.

[0011] The balancing propeller is a propeller. When the propeller rotates in the water, it generates an upward thrust to keep the float horizontal.

[0012] This utility model relates to a floating platform for reoxygenation devices. It has a reasonable structure, scientific design, and is easy to use. It uses four floats to provide balancing force for the reoxygenation device. The slider on the balance frame slides under gravity, which realizes the opening and closing of the motor circuit. The motor drives the balance paddle to rotate, and the thrust makes the lifting platform rebalanced. This effectively reduces the shaking of the lifting platform, reduces equipment wear, and increases service life. Attached Figure Description

[0018] Example 1: A floating platform for a reoxygenation device 7. The reoxygenation device 7 is installed on the platform, which includes floats 1, connecting steel cables, and a self-balancing device. Four floats 1 are connected and fixed in a square shape. The reoxygenation device 7 is vertically installed at the center of the square. The outer edges of the four floats 1 are connected to fixed blocks on the shore and lake bottom respectively via connecting steel cables. The self-balancing device is installed on the floats 1 and connected to the power supply 6 of the reoxygenation device 7. Wherein:

[0019] The self-balancing device includes a balancing frame, balancing paddles 2 and motors 3. The balancing frame is in the shape of a cross and is horizontally installed near the center of the float 1. Four balancing paddles 2 are installed vertically at equal intervals on the bottom edge of the float 1. Four motors 3 are installed on the float 1. Each of the four ends of the balancing frame is connected to a motor 3. The balancing paddles 2 are connected to the shafts of the motors 3.

[0020] The balancing frame comprises four sets of slide rails, each pair perpendicular to the other. Each set includes two parallel slide rods 4 and a slider 5. The slider 5 is mounted on the two slide rods 4 and slides along them. The front section of each slide rod 4 near the center of the balancing frame is made of insulating material, while the rear section away from the center is made of conductive material. The slider 5 is made of conductive material. The rear section of each slide rod 4 is connected to the motor 3 via a wire. The rear end of each slide rod 4 is tilted upwards at an angle not exceeding 5°. The four ends of the balancing frame point to four balancing propellers 2. The balancing propellers 2 are propellers; when they rotate in the water, they generate upward thrust, maintaining the balance of the float 1.

[0021] When the hoisting platform tilts to one side due to water surface fluctuations or wind, the balance frame on the hoisting platform tilts synchronously with the hoisting platform. The slider 5 on the downward tilting section of the balance frame slides towards the rear end of the slide rail on the same side under the influence of gravity. When the slider 5 contacts the conductive section of the slide rod 4, the circuit of the slide rod 4, the power supply 6, and the motor 3 is closed. The power supply 6 supplies power to the motor 3, and the motor 3 drives the balance paddle 2 to rotate through the shaft. When the balance paddle 2 rotates, it generates a downward thrust, which is used to make the float 1 on that side rise, so that the float 1 is restored to balance. When the float 1 is rebalanced, because the rear end of the slide rod 4 tilts upward, the slider 5 slides towards the front end of the slide rod 4 under the action of gravity. When the slider 5 slides back to the insulating section of the slide rod 4, the circuit of the motor 3 is disconnected, and the motor 3 is de-energized and stops working.
