Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] This invention provides a floating mechanism for a wastewater treatment bioreactor, such as... Figures 1-5 As shown, the system includes a float box 1, a counterweight 2, and a connecting rod 3. The float box 1 and the counterweight 2 are connected by the connecting rod 3. The outer ring of the float box 1 is an airbag ring 1-1, and the middle of the airbag ring 1-1 is the bottom plate 1-2 of the float box 1. A fixing ring 4 is provided outside the airbag ring 1-1, and several buoyancy rods 5 are rotatably connected to the fixing ring 4. The several buoyancy rods 5 are equally spaced, and a float cylinder 6 is fixed at the end of the buoyancy rod 5 away from the float box 1. The float box 1 has a built-in chip. The magnetic block 8, electromagnet 9, and motor are all electrically connected to the built-in chip. The buoyancy force on the entire floating mechanism includes the buoyancy force provided by the airbag ring 1-1 and the buoyancy force provided by the float cylinder 6. The float cylinder 6 is circumferentially arranged around the float box 1 by the buoyancy rods 5, which disperses the buoyancy force on the entire floating mechanism instead of concentrating it on the airbag ring, making the entire floating mechanism more stable when floating and less prone to tipping over.

[0025] A strong magnet 7 is fixed at one end of the buoyancy rod 5 near the float box 1. Several pairs of magnetic blocks 8 are fixed outside the airbag ring 1-1. Each pair of magnetic blocks 8 corresponds to the buoyancy rod 5. When the buoyancy rod 5 rotates, the end near the float box swings between a pair of magnetic blocks 8. Magnetic coils are provided inside the magnetic blocks 8.

[0026] When there are waves on the water surface, the float 6 moves up and down with the waves, and the buoyancy rod 5 swings. When the buoyancy rod 5 swings, the magnetic field line emitted by the strong magnet 7 at its end cuts the magnetic field coil in the magnetic field block 8. The magnetic field coil generates current, and the chip receives the current signal from the magnetic field coil.

[0027] Several electromagnets 9 are also fixed outside the airbag ring 1-1. Each electromagnet 9 is located above each pair of magnetic blocks 8. When the buoyancy rod 5 rotates, the electromagnet 9 generates magnetism to suppress the rotation of the buoyancy rod 5. When the chip receives the current signal from the magnetic coil, the electromagnet 9 is energized and generates magnetism, which generates attraction on the strong magnet 7 at the end of the buoyancy rod 5, thereby causing the buoyancy rod 5 to rotate and force the float 6 to press down on the water surface, thereby stabilizing the floating mechanism.

[0028] The fixed ring 4 is divided into a curved section 41 and a straight section 42, the curved section 41 and the straight section 42 are arranged at intervals, the floating rod 5 is rotatably connected to the fixed ring 4 at the straight section 42, the straight section 42 is provided with a pair of limiting blocks 421, the floating rod 5 is rotatably connected to the fixed ring 4 between the pair of limiting blocks 421, the straight section 42 ensures that the floating rod 5 can rotate smoothly, and the limiting blocks 421 prevent the floating rod 5 from sliding on the fixed ring 4.

[0029] The bottom plate 1-2 is provided with a perforation 1-3, the perforation 1-3 is divided into four regions, the four regions are arranged at equal intervals, the bottom plate 1-2 is provided with a rotating baffle 1-4, the floating box 1 is provided with a motor, the rotating baffle 1-4 is connected to the output end of the motor, the rotating baffle 1-4 has four baffles, the four baffles can cover the four regions where the perforation 1-3 is located, and the rotating baffle 1-4 covers the perforation 1-3 in the default stable state.

[0030] When the chip receives the current signal of the plurality of magnetic sensing blocks 8, it is judged that the wave is large, at this time the electromagnet 9 is no longer powered, that is, it no longer has magnetism, at this time the motor is started. The rotating baffle 1-4 rotates away from the perforation 1-3 region, water flows into the floating box 1 from the perforation 1-3, so that the floating box 1 sinks, thereby causing the center of gravity of the whole mechanism to move downward, improving the stability of the whole mechanism. It should be noted that the rotating baffle 1-4 is controlled by the motor to cover the perforation 1-3 region again after a fixed time interval, and the fixed time interval is set according to different environments.

[0031] The counterweight 2 is provided with a flow stabilizing plate 10 on the upper and lower surfaces, the area of the flow stabilizing plate 10 is greater than that of the counterweight 2, no matter how the water surface is disturbed, the underwater flow is often stable and does not move, when the wave on the water surface drives the floating mechanism to have a tendency to swing, the counterweight 2 below the floating box 1 also has a tendency to swing, at this time the flow stabilizing plate 10 has greater resistance with water, inhibiting the swing and further improving the stability of the mechanism.

[0032] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and deformations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
