[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figure 1-Figure 5 The present invention provides a mobile aerator based on differential speed control, comprising:

[0027] Hull components,

[0029] Two groups of thrust generating components are respectively arranged on both sides of the bottom of the hull component, and two groups of aeration mechanisms are respectively arranged in the two groups of thrust generating components. An opening is arranged at one end of the thrust generating component close to the tail of the hull component, and the opening is used to diffuse bubbles.

[0030] The main function of the hull assembly is to enable the mobile aerator to float on the water surface; the air supply mechanism is used to supply air to the aeration mechanism; the aeration mechanism is used to generate bubbles underwater to increase the contact area between water and air; the main function of the thrust generating assembly is to generate thrust to push the hull assembly forward by allowing the bubbles generated by the aeration mechanism to be ejected from the tail opening; by arranging a thrust generating assembly on both sides of the bottom of the hull assembly, the thrust generated by the thrust generating assembly can be controlled by controlling the operation of the air supply assembly, thereby achieving the purpose of controlling the direction of travel of the hull assembly. On the whole, the driving power of the hull assembly of the present invention is directly provided by the air supply mechanism, and the aeration mechanism generates bubbles underwater to increase the contact area between air and water, achieving the aeration effect while driving the hull assembly to move and turn, achieving uniform oxygenation in the entire pond, simplifying the structure, and reducing the overall power consumption, which is superior to replacing the traditional propeller power, and can avoid entanglement of water plants during travel and improve working stability.

[0031] To further optimize the solution, a battery (not shown in the figure) and a control unit (not shown in the figure) are also provided in the hull assembly, the battery is used to provide electrical energy, and the control unit is electrically connected to the air supply mechanism.

[0032] According to a further optimized solution, the thrust generating assembly includes a frame 1, which is horizontally fixedly connected below the hull assembly, an aeration mechanism is arranged in the frame 1, and an opening is arranged at the rear end of the frame 1 for allowing bubbles to diffuse backwards.

[0033] like Figure 2 As shown, the frame 1 is connected to each other by square steels to form a rectangular truss structure, which is horizontally fixedly connected under the hull assembly to reduce the travel resistance.

[0034] According to a further optimized solution, the aeration mechanism includes a plurality of aeration pipes 7, which are horizontally fixedly connected to the bottom of the frame 1, the aeration pipes 7 are connected to the inner side of the frame 1, and the plurality of aeration pipes 7 are respectively connected to the air supply mechanism.

[0035] like Figure 2 As shown, a plurality of aeration pipes 7 are horizontally fixedly connected between two opposite square steels at the bottom of the frame 1 , so that the generated bubbles can contact the water inside the frame 1 and the water below the frame 1 .

[0036] According to a further optimized solution, the surface of the aeration tube 7 is wrapped with a sponge, and the sponge is used to make the aeration tube 7 produce dense bubbles underwater.

[0037] According to a further optimization scheme, baffles 6 are fixedly connected to the front side wall and two opposite side walls of the frame 1 , respectively, and the baffles 6 are used to ensure that the bubbles generated by the aeration pipe 7 diffuse out from the rear opening of the frame 1 .

[0038] like Figure 2 As shown, a slot (not shown) is provided on the vertically arranged square steel of the frame 1, and the two ends of the three sets of baffles 6 are respectively fixedly connected to the front end and two opposite sides of the frame 1 through the slot. Figure 5 As shown, the bubbles generated by the aeration pipe 7 inside the frame 1 are separated by the baffle 6 and move toward the opening at the tail of the frame 1, and the self-propelled aerator is achieved by utilizing the reverse thrust of the bubble movement.

[0039] To further optimize the solution, the front ends of the two sets of racks 1 are respectively fixedly connected with integrated detectors 2, and the integrated detectors 2 are used to detect the dissolved oxygen situation in the water body and detect obstacles ahead.

[0040] like Figure 1 As shown, the integrated detector 2 is composed of a dissolved oxygen meter and an infrared distance measuring sensor, and is fixedly integrated in the same box. The integrated detector 2 is electrically connected to the control unit.

[0041] To further optimize the solution, the control unit is electrically connected to the integrated detector 2. Through the monitoring signal fed back by the integrated detector 2, the control unit can control the start and stop and automatic cruise of the aerator. At the same time, the control unit also includes a remote control receiving module, which can support manual remote control.

[0042] According to a further optimized solution, the air supply mechanism includes an air pump 3 fixedly connected to the hull assembly, an air outlet end of the air pump 3 is connected to one end of an air pipe 8, and the other end of the air pipe 8 is connected to a plurality of aeration pipes 7.

[0043] The air pipe 8 penetrates the hull assembly and communicates with one end of the connecting air pipe built into the square steel of the frame 1, and the other end of the connecting air pipe is connected with a plurality of aeration pipes 7 in a socket connection. The built-in connecting air pipe can prevent the air bubbles in the frame 1 from encountering obstacles when moving toward the tail.

[0044] According to a further optimization scheme, the hull assembly includes two groups of hulls 5 arranged in parallel, the two groups of hulls 5 are fixedly connected by a plurality of cross beams 9, the two groups of frames 1 are fixedly connected to the bottom of the two hulls 5, and the two air pumps 3 are fixedly connected to the two hulls 5.

[0045] like Figure 1 The catamaran shown in the figure can make the whole structure of the aerator flat, effectively prevent rollover and improve structural stability.

[0046] According to a further optimization scheme, a solar panel 4 is arranged between the two hulls 5 , and the solar panel 4 is fixedly connected to a plurality of beams 9 . The solar panel 4 is used to provide electrical energy to the air pump 3 .

[0047] The solar panel 4 directly charges the battery, which can improve the battery life and the overall working stability of the aerator.

[0048] The working process of this embodiment is as follows: Figure 4 As shown, after the aerator is powered on and self-checked, it first determines whether there is an obstacle in front through the integrated detector 2. If not, the two sets of air pumps 3 are started.

[0049] During driving, the aerator continues to use the integrated detector 2 to first determine whether there is an obstacle ahead, and then determine the dissolved oxygen values ​​on both sides of the aerator. When there is no obstacle ahead, if the integrated detector 2 detects that the dissolved oxygen value on the left is small, the control unit adjusts the voltage of the right air pump 3 according to the feedback signal, increases the pumping volume of the right air pump 3, and realizes the left turn of the aerator; similarly, if the dissolved oxygen value on the right is small, the voltage is adjusted to increase the pumping volume of the left air pump 3 to realize the left turn. When the integrated detector 2 detects that there is an obstacle ahead, the control unit first adjusts the voltage to reduce the pumping volume of the air pumps 3 on both sides to achieve deceleration, and then the integrated detector 2 determines the dissolved oxygen values ​​on both sides, and repeats the above turning process, turning in the direction of low dissolved oxygen value, and finally realizing uniform oxygenation of the whole pond through the movement of the aerator on the water surface.
