DETAILED DESCRIPTION

[0039] The embodiments of the present invention are described below in conjunction with the drawings in the embodiments of the present invention. The terms used in the implementation mode of the present invention are only used to explain the specific embodiments of the present invention, and are not intended to limit the present invention. The embodiments of the present application are described below in conjunction with the drawings.

[0040] Example: Figure 1-Figure 2 As shown, a buoy-type aeration and stirring device is provided, wherein a floating platform 1 is mounted on a self-priming aeration and stirring component, and is used to keep the self-priming aeration and stirring component suspended underwater, wherein the self-priming aeration and stirring component comprises a self-priming stirring chamber 2, an air intake chamber 3 and a filter chamber 4, an impeller 5 is arranged in the self-priming stirring chamber 2, the self-priming stirring chamber 2 is connected with the air intake chamber 3 and the filter chamber 4, the air intake chamber 3 extends to the water surface through an air intake pipe 6, and a silencer pipe 61 is arranged at the end of the air intake pipe 6, the impeller 5 is connected to the rotor assembly in the self-priming aeration and stirring component, and the impeller 5 is driven to rotate, and the rotation The centrifugal force generated by the rotating impeller 5 forms a negative pressure at the inlet of the impeller 5, guiding the water flow through the filter chamber 4 into the self-priming mixing chamber 2. At the same time, the gas enters the air inlet chamber 3 through the air inlet pipe 6, sucking in air and water. The kinetic energy of the impeller 5 is used to mix a certain proportion of gas and water in the mixing chamber. Under the action of centrifugal force, the gas-water two-phase flow is rectified through the flow channel along the tangential direction of the impeller 5 and diffused in the circumferential direction. The self-priming mixing chamber 2 is provided with a plurality of output chambers 7. Through the output of the output chambers 7, the fine and tiny bubbles are fully integrated with the water, thereby achieving the effect of aeration and oxygenation.

[0041] Among them, reference Figure 2-Figure 5As shown, the filter chamber 4 is mainly divided into an inner cavity 41 and an outer cavity 42. The outer cavity 42 is wrapped around the outer side of the inner cavity 41. The water flows through the outer cavity 42 in sequence to reach the inner cavity 41, and then enters the self-priming stirring chamber 2 through the inner cavity 41 to participate in the mixing of air and water; wherein, the inner cavity 41 is mainly formed by the first filter screen 411, and the inner cavity 41 is provided with a first chamber 412 and a second chamber 413. The first chamber 412 is communicated with the first filter screen 411, and the second chamber 413 is connected to the extension channel 8. The extension channel 8 extends to a position close to the water surface as soon as an opening is opened. A partition 414 is slidably installed between the chamber 412 and the second chamber 413, and the partition 414 is configured to control the first chamber 412 or the second chamber 413 to be connected to the self-priming stirring chamber 2 when sliding; through the action of the partition 414, when the first chamber 412 is connected to the self-priming stirring chamber 2, water flows from the outer chamber 42 and the inner chamber 41 to the first chamber 412, and flows into the self-priming stirring chamber 2; when the second chamber 413 is connected to the self-priming stirring chamber 2, water flows from the extension channel 8 to the second chamber 413, and flows into the self-priming stirring chamber 2;

[0042] The outer chamber 42 is mainly surrounded by a plurality of second filter screens 421, and a side hole 9 is provided between the output chamber 7 and the outer chamber 42, and the side hole 9 is configured to be opened when the second chamber 413 is connected to the self-priming stirring chamber 2, and closed when the first chamber 412 is connected to the self-priming stirring chamber 2;

[0043] Based on the above, the self-priming aeration and stirring assembly includes the following functions:

[0044] When the aeration and stirring device is not started for a long time, in this state, a certain amount of sediment will accumulate on one side of the second filter screen 421, or after the aeration and stirring device has been working for a certain period of time, a certain amount of impurities will accumulate on the second filter screen 421; the partition 414 slides to control the second chamber 413 to be connected with the self-priming stirring chamber 2. At this time, when the impeller 5 rotates, the water flows from the extension channel 8 into the second chamber 413 and into the self-priming stirring chamber 2. Due to the effect of the extension channel 8, water is taken at a near horizontal surface. On the one hand, the clarity of the incoming water is maintained. On the other hand, when the device is not started for a long time, water is not taken from the second filter screen 421 to avoid blockage and damage to the machine. After taking water, the impeller 5 rotates, and under the centrifugal action, a part of the gas-water mixed water flow is output from the side hole 9, thereby entering the outer cavity 42 and flushing the second filter screen 421 in the opposite direction to remove sediment or impurities.

[0045] In other working states, the partition 414 slides to control the first chamber 412 to be connected with the self-priming mixing chamber 2. At this time, when the impeller 5 rotates, water flows from the outer chamber 42 to the inner chamber 41 into the first chamber 412, and then enters the self-priming mixing chamber 2 for gas-water mixing.

[0046] Among them, reference Figure 3-Figure 4As shown, the floating platform 1 is connected to the self-priming aeration and stirring assembly through a connecting rod 10, which supports the self-priming aeration and stirring assembly to be suspended underwater. A top water inlet 11 is provided at a position of the connecting rod 10 close to the floating platform 1. The outside of the top water inlet 11 is wrapped with a filter screen. A channel is provided in the connecting rod 10 along the vertical direction to form an extension channel 8. One end of the extension channel 8 is connected to the second chamber 413, and the other end of the extension channel 8 is connected to the top water inlet 11.

[0047] refer to Figure 4 As shown, for the switch control of the top water inlet 11, a sealing plate 12 can be slidably installed in the connecting rod 10, and the sealing plate 12 overlaps with the top water inlet 11 to seal and close the top water inlet 11, or staggers with the top water inlet 11 to open the top water inlet 11. A power component 13 is installed on the sealing plate 12, and the power component 13 is used to drive the sealing plate 12 to move. The power component 13 can be a telescopic cylinder structure, or a screw rod matching screw rod nut structure, etc., to achieve reciprocating motion to give the sealing plate 12 a reciprocating force;

[0048] For the sealing plate 12 to control the switch of the top water inlet 11, it can be achieved by switching back and forth from complete covering to exposure, or multiple channels can be set on the sealing plate 12. The top water inlet 11 also has a multi-channel structure. The sealing plate 12 slides to control the overlap and stagger of the two channels to achieve the switch operation, which can greatly reduce the displacement of the sealing plate 12.

[0049] In a specific embodiment, reference Figure 3-Figure 5 As shown, a linkage plate 14 is slidably installed between the outer cavity 42 and the output cavity 7, and a plurality of guide holes 141 are opened on the linkage plate 14. As the linkage plate 14 controls the guide holes 141 to overlap or stagger with the side holes 9; the linkage plate 14 is connected to the sealing plate 12 through a rope 15, and as the sealing plate 12 moves, the top water inlet 11 is sealed and closed, and the linkage plate 14 moves synchronously to stagger the guide holes 141 with the side holes 9, or as the sealing plate 12 moves, the top water inlet 11 is sealed and opened, and the linkage plate 14 moves synchronously to overlap the guide holes 141 with the side holes 9; and there are multiple guide holes 141 and side holes 9, which are distributed between the second filter screen 421 and the first filter screen 411, and the inclination angles of the inner cavities 41 of the side holes 9 are different.

[0050] One end of the partition 414 is rotatably connected in the inner cavity 41, and the other end is slidably installed in the inner cavity 41 and connected to the linkage plate 14. The partition 414 is an elastic structure or a retractable component. When the guide hole 141 and the side hole 9 are staggered or overlapped by the linkage plate 14, the first chamber 412 or the second chamber 413 is synchronously controlled to be connected with the self-priming stirring chamber 2.

[0051] Based on the above, the power assembly 13 controls the movement of the sealing plate 12, and synchronously drives the linkage plate 14 to move. When the linkage plate 14 moves, the side hole 9 is opened and closed, and the partition plate 414 switches the first chamber 412 or the second chamber 413 to be connected with the self-priming stirring chamber 2;

[0052] That is, with the opening of the top water inlet 11, the second chamber 413 is connected to the self-priming stirring chamber 2, and the side hole 9 is opened to perform the above-mentioned cleaning function; with the closing of the top water inlet 11, the first chamber 412 is connected to the self-priming stirring chamber 2, and the side hole 9 is closed to perform the above-mentioned conventional aeration and stirring function.

[0053] In a specific embodiment, one end of the second filter screen 421 is movably connected in the outer cavity 42, and the other end is connected to the linkage plate 14. As the linkage plate 14 slides, the inclination angle of the second filter screen 421 is synchronously adjusted; and when the guide hole 141 and the side hole 9 are staggered, the angle between the filtering surface of the second filter screen 421 and the bottom of the outer cavity 42 is an acute angle.

[0054] Based on the above, the movement of the linkage plate 14 can also drive the angle adjustment of the second filter screen 421. For the second filter screen 421, when it is not working, it is in an acute angle state with the bottom of the outer cavity 42 to prevent sediment from accumulating on the second filter screen 421. During the conventional aeration and stirring function, the angle of the second filter screen 421 is adjusted to a vertical state, or a nearly vertical state. In addition to the above-mentioned reverse flushing by water flow, the second filter screen 421 can also be scraped during the angle adjustment process to ensure that there is no sediment on one side of the second filter screen 421.

[0055] The angle between the side hole 9 and the vertical direction gradually decreases from approaching to moving away from the second filter screen 421. By setting the side hole 9 in this state, the water flow can be guided to flow in layers in the outer cavity 42 toward the second filter screen 421 to avoid turbulence affecting fluidity.

[0056] In a specific embodiment, reference Figure 5 As shown, a slot 16 is provided in the outer cavity 42 at the movable connection of the second filter screen 421, a slider 17 is slidably installed in the slot 16 along the vertical direction, the second filter screen 421 is movably connected to the slider 17, a counterweight is provided on the slider 17 and / or an elastic member 18 is installed on the top of the slider 17; the elastic member 18 tends to drive the slider 17 to slide toward the opening direction of the slot 16.

[0057] Based on the above, when the second filter screen 421 is in a vertical state, the second filter screen 421 will be squeezed to rotate and connect one end to drive the slider 17 to move upward to provide space; when the device finishes working, the sealing plate 12 is reset, and the rope 15 is reset. At this time, the gravity of the slider 17 or the elastic force of the elastic member 18, or the synergistic effect of the two, squeezes the second filter screen 421 to move downward, thereby driving the second filter screen 421 and the end connected to the linkage plate 14 to slide toward one side. Therefore, during the above-mentioned second filter plate adjustment process, it can be adjusted to a nearly vertical state, which is more suitable for the reset movement of the second filter plate.

[0058] In one embodiment, in addition to the above structure, a traction mechanism is installed on the floating platform 1, and the traction mechanism includes a plurality of traction ropes 19 and a release plate, and each traction rope 19 is connected to the floating platform 1 from different directions; the release plate is installed on the floating platform 1, and a plurality of through holes are opened on the release plate, and each traction rope 19 part passes through a through hole, and when any traction rope 19 applies force to the release plate, the release plate is configured to lock the traction rope 19 in the through hole in the corresponding direction, and release the traction rope 19 in the through holes in the other directions;

[0059] refer to Figure 6 As shown, the release plate includes a lower plate 20 and an upper plate 22, and the lower plate 20 is provided with a plurality of first through holes 21; the upper plate 22 is slidably mounted on the lower plate 20, and the upper plate 22 is provided with second through holes 23 corresponding to each first through hole 21, and the corresponding first through holes 21 and second through holes 23 form a group of through holes, and the first through holes 21 and the second through holes 23 in a group of through holes are initially in a partially staggered state, and the first through holes 21 and the second through holes 23 in the two groups of through holes in opposite directions are symmetrically arranged; an elastic structure 24 is installed on the upper plate 22, and the elastic structure 24 tends to drive the upper plate 22 and the lower plate 20 to be in the initial state; each upper plate 22 is provided with a cushion block 25 at each second through hole 23, and the cushion block 25 is configured to bear the pressure of the traction rope 19 and drive the upper plate 22 to move in the direction of the pressure.

[0060] refer to Figure 6As shown, the lower plate 20 and the upper plate 22 are coaxially mounted on a central column 26, wherein a circular hole is provided at the center of the upper plate 22, and the inner wall of the circular hole is connected to the central column 26 through an elastic structure 24, and the elastic structure 24 is a structure with elastic force such as a spring or an elastic pad. Taking a group of through holes as an example, one end of the traction rope 19 passes through the second through hole 23 of the upper plate 22 and the first through hole 21 of the lower plate 20, and then naturally hangs underwater, and a counterweight can be tied to the hanging end. In the initial state, the first through hole 21 and the second through hole 23 are partially staggered. At this time, the traction rope 19 is bent between the second through hole 23 and the first through hole 21, and the traction rope 19 is fixed to a certain extent on the floating platform 1 under the action of the counterweight and friction force, and the traction rope 19 forms a pulling stabilization device In the water, when the position of the floating platform 1 in the water needs to be adjusted, the traction rope 19 is pulled at one end, which will squeeze the pad 25 and drive the upper plate 22 to move in the corresponding direction. The second through hole 23 and the first through hole 21 at this position are more misaligned, and the second through hole 23 and the first through hole 21 at the relative position move in the overlapping direction. In this state, the traction rope 19 on the force-bearing side is fixed more tightly, and the friction on the opposite side is released. When pulling, the traction rope 19 on the opposite side only needs to overcome the force of the counterweight to release the length of the traction rope 19, so that the floating platform 1 moves in the force direction. When the adjustment is completed, the traction rope 19 is released, and under the action of the elastic structure 24, the lower plate 20 and the upper plate 22 are reset, and all the pull ropes are in the initial fixed state.
