Description

Technical Field

[0001] The invention relates to the technical field of oxygenators, and in particular to a movable automatic aerator. Background Art

[0002] With the continuous improvement of human living standards, people pay more and more attention to the pollution of rivers, reservoirs and lakes, and invest a lot of money every year to control the pollution of rivers, reservoirs and lakes. The most common way to control river pollution is aeration. However, due to simple aeration, the pollution situation of the river cannot be accurately known, so the aeration effect is not ideal. When facing relatively large reservoirs, the aeration device cannot fully aerate the entire lake surface. Some areas are severely polluted and some areas have low dissolved oxygen concentrations. How to accurately locate the lake surface, detect water quality in real time and upload data in time is particularly important.

[0003] The current aeration systems include the following:

[0004] (1) Mechanical aeration system: A method that uses mechanical equipment to fully mix the wastewater and sludge in the aeration tank, continuously update the liquid level of the mixed liquid, and contact it with air to increase the dissolved oxygen in the water.

[0005] (2) Air aeration system: compressed air aeration, the blower supplies a certain amount of air, and transports the air through the pipe to the aerator installed at the bottom of the pool. The air is formed into bubbles of different sizes through the aerator. The bubbles are formed at the outlet of the aerator, rise and flow, and finally burst at the liquid surface. This process plays a role in transferring oxygen to the water.

[0006] (3) Jet aeration system: The jet aerator cuts and crushes the air introduced by the blower into microbubbles by jetting the mixed liquid at high speed, and then allows the mixed liquid and microbubbles to fully mix and contact, thereby enhancing the oxygen transfer efficiency.

[0007] The existing non-intelligent aeration system has a fixed aeration position and cannot be moved at any time. It can only perform local aeration for larger lakes, and it is difficult to increase the dissolved oxygen in the entire lake. Secondly, it is impossible to detect the water quality of the entire lake at any time, and it is impossible to accurately locate the pollution of the lake. It is impossible to grasp the sudden increase of pollutants in the river in a timely manner. The aeration time can only be completed by simple timing, and it cannot be aerated in time according to the water quality. Summary of the invention

[0008] In order to solve the above problems, the present invention discloses a movable automatic aerator, comprising a plurality of floating boats, a control box being fixedly connected to the middle floating boat, rotating shafts extending from both sides of the lower end of the control box, a plurality of impellers being sleeved on the rotating shafts, a guide plate being fixedly connected to the middle part of the lower end of each of the floating boats along the length direction of the floating boat, a steering gear being fixedly connected to the heads of the floating boats on both sides, a rudder plate being fixedly connected to the output end extending downward from the rudder plate, a fixed baffle being arranged at the lower part of the front end of the middle floating boat, and the fixed baffle and the guide plate being perpendicular. The aerator floats directly on the water surface, and the rotation of the impeller stirs up water splashes and increases the oxygen content of the water body. At the same time, the reaction force generated pushes itself to move on the water surface. In this way, oxygenation of the water surface in different areas can be achieved, and the guide plate is set to ensure that the aerator can be stable to a certain extent, and the steering gear and rudder are set for steering the aerator. At the same time, during the operation of the aerator, the reaction force generated is too large, and the aerator moves too fast on the water surface, which may easily cause insufficient oxygenation speed on the water surface. Therefore, a fixed baffle perpendicular to the guide plate is provided. At the same time, when the rudder plate rotates and is perpendicular to the guide plate, the effect generated is consistent with that of the fixed baffle. The provision of this structure can increase the resistance of the aerator movement, thereby reducing the movement speed of the aerator and ensuring the effect of oxygenation.

[0009] Preferably, the aerator further comprises a bottom frame, which is rectangular, and a plurality of pontoons arranged side by side are fixedly connected to the bottom frame. The bottom frame is provided to fix all the pontoons together to form a whole.

[0010] Preferably, the four corners of the bottom frame are fixedly connected with support columns, a photovoltaic panel is arranged above the control box, and the upper end of the support column is fixedly connected to the lower end surface of the photovoltaic panel. Since the aerator moves on the water surface, if it is powered by wire, it is troublesome to wind up and release the lower cable, and the photovoltaic panel is arranged to reduce the dependence on external power supply.

[0011] Preferably, the upper end of the floating boat is fixedly connected with a support seat, and the rotating shaft passes through the upper part of the support seat. The support seat is used to support the rotating shaft, and a bearing is arranged between the rotating shaft and the support seat.

[0012] Preferably, the control box is provided with a positioning module, a battery and a drive motor, and the output end of the drive motor is coaxially fixedly connected to the rotating shaft. The positioning module is satellite positioning, and the battery is used to power the aerator and store the electric energy generated by the photovoltaic panel. The motor shaft is extended from both ends of the drive motor and is directly connected to the rotating shaft. Furthermore, the output end of the drive motor is connected to the reducer, and the output end of the reducer is connected to the rotating shaft.

[0013] Preferably, a dissolved oxygen detector and an ammonia nitrogen detector are provided at the bottom of the floating boat, which are used to monitor the oxygen and ammonia nitrogen content of the water body and indicate whether to start the aerator.

[0014] Preferably, the aerator also includes a camera and a plurality of infrared sensors arranged around the aerator. The cameras are used to monitor the situation around the aerator. Furthermore, through artificial intelligence, it is possible to automatically identify whether there are obstacles on the water surface. The infrared sensors are used to measure the distance to the obstacles and control the steering gear to avoid obstacles. In conjunction with the positioning module, the movement path of the aerator can be pre-planned to realize fully automated operation of the aerator. Furthermore, the infrared sensors can be upgraded to radar sensors.

[0015] The beneficial effects of the present invention are as follows: the aerator can move on the water surface according to a preset route or according to the ammonia, nitrogen and oxygen content of the water body, thereby accurately aerating the polluted area on the water surface.

[0022] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] like Figures 1 to 4As shown, a movable automatic aerator includes a plurality of pontoons 2, which are of conventional structure and are injection molded. A control box 10 is fixedly connected to the middle pontoon 2. A rotating shaft 8 is extended on both sides of the lower end of the control box 10. A plurality of impellers 7 are sleeved on the rotating shaft 8. The impellers 7 rotate with the rotating shaft 8 and stir up water splashes, thereby increasing the contact area between the water flow and the air, thereby increasing the oxygen content of the water body. At the same time, the aerator is not fixed, so under the reaction force of the impeller 7, the aerator is moved on the water surface.

[0024] The middle part of the lower end of each pontoon 2 is fixedly connected with a guide plate 6 along the length direction of the pontoon 2. The guide plate 6 is arranged so that the flow direction of the water flow is as consistent as possible with the length direction of the pontoon 2, thereby ensuring that the moving direction of the pontoon 2 remains stable. The heads of the pontoons 2 on both sides are fixedly connected with steering gears 3, and the output ends extending downward from the steering gears 3 are fixedly connected with rudder plates 1. When the steering gears 3 work, the angle of the rudder plates 1 can be changed. At this time, the force magnitude and direction of the rudder plates 1 are changed. The steering gears 3 and the rudder plates 1 are used for the direction-changing operation during the movement of the aerator. A fixed baffle 4 is arranged at the lower front end of the middle pontoon 2, and the fixed baffle 4 and the guide plate 6 are perpendicular, and the fixed baffle 4 and the guide plate 6 are arranged vertically, so that the resistance of the aerator is increased during the movement and the moving speed is reduced. If the fixed baffle 4 is not arranged, the aerator moves too fast, resulting in poor oxygenation effect in the water area. The fixed baffle 4 and the guide plate 6 are further controlled to be perpendicular to achieve the same effect as the fixed baffle 4.

[0025] The aerator also includes a bottom frame 5, which is rectangular and made of square steel pipes. A plurality of pontoons 2 arranged side by side are fixedly connected to the bottom frame 5, and bolts and other connecting parts are used to achieve fixed connection between the bottom frame 5 and the pontoons 2.

[0026] The four corners of the bottom frame 5 are fixedly connected with support columns 9, which are also square steel pipes. A photovoltaic panel 11 is arranged above the control box 10, and the upper end of the support column 9 is fixedly connected to the lower end surface of the photovoltaic panel 11. The photovoltaic panel 11 is used to generate electricity, thereby reducing dependence on external power supply. The aerator is used for oxygenation on the water surface and can move freely, so the cable fixing method is not suitable.

[0027] The upper end of the floating boat 2 is fixedly connected to the support seat 12, that is, the lower part of the support seat 12 is fixedly connected to the floating boat 2 by inserting bolts, the rotating shaft 8 passes through the upper part of the support seat 12, and a bearing is arranged between the rotating shaft 8 and the support seat 12.

[0028] The control box 10 is provided with a positioning module 15, a battery 14 and a drive motor 13. The positioning module 15 is a satellite positioning module for obtaining the position of the aerator in real time, and the battery 14 is used to supply power and store the electric energy generated by the photovoltaic panel 11. The output end of the drive motor 13 is coaxially fixedly connected with the rotating shaft 8. When the drive motor 12 is started, the rotating shaft 8 rotates, and the impeller 7 rotates.

[0029] A dissolved oxygen detector 16 and an ammonia nitrogen detector 17 are provided at the bottom of the floating boat 2. The dissolved oxygen detector 16 and the ammonia nitrogen detector 17 are used to detect the oxygen content and the ammonia nitrogen content in the water body, thereby providing a basis for the automatic operation of the aerator.

[0030] The aerator also includes a camera 18, and a plurality of infrared sensors 19 are arranged around the aerator. The camera 18 is used to obtain the situation of the water surface, and through the image recognition technology, it is identified whether there are obstacles on the water surface, and the distance between the obstacles and the infrared sensor 19 is measured, and the aerator can be combined with the positioning module 15 to move on the water surface according to the established planned route, and avoid the obstacles in the shortest distance, and finally cooperate with the dissolved oxygen detector 16 and the ammonia nitrogen detector 17 to realize fully automatic operation.

[0031] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
