Description

Technical Field

[0001] This invention belongs to the technical field of aeration devices for aquaculture water bodies, and particularly relates to a mobile aerator based on differential speed control. Background Technology

[0002] Aerators are essential facilities in aquaculture, playing a crucial role in regulating the oxygen content of water. Currently, commonly used aerators include five types: spray aerators, impeller aerators, paddlewheel aerators, wave aerators, and micro-pore aerators. Most of these types operate in a fixed installation. When fixed aerators are placed in large ponds, the poor water flow and the aerator's fixed position result in uneven oxygenation and limited oxygenation effect. Mobile aerators, on the other hand, require propellers or paddle wheels as a power source, leading to high power consumption and short operating time. Summary of the Invention

[0003] The purpose of this invention is to provide a mobile aerator based on differential speed control to solve the above-mentioned problems and achieve the goal of combining aeration and mobility, so as to realize the functions of movement and turning at the same time by using the dense bubbles generated by the aerator and its mechanism to aerate.

[0004] To achieve the above objectives, the present invention provides the following solution: a mobile aerator based on differential speed control, comprising:

[0005] Hull components,

[0006] Two sets of aeration components are symmetrically arranged on both sides of the hull component. Each aeration component includes an air supply mechanism disposed in the hull component and an aeration mechanism disposed below the hull component. The aeration mechanism is connected to the air supply mechanism and is used to generate bubbles underwater to achieve an aeration effect.

[0007] Two sets of thrust generating components are respectively disposed on both sides of the bottom of the hull assembly. Two sets of aeration mechanisms are respectively disposed inside the two sets of thrust generating components. An opening is provided at one end of the thrust generating component near the stern of the hull assembly, and the opening is used to diffuse the bubbles.

[0008] Preferably, the thrust generating component includes a frame, which is horizontally fixedly connected to the lower part of the hull component, the aeration mechanism is disposed within the frame, and the rear end of the frame is provided with an opening for allowing bubbles to diffuse backward.

[0009] Preferably, the aeration mechanism includes a plurality of aeration pipes, which are horizontally fixedly connected to the bottom of the frame, and the aeration pipes are connected to the inner side of the frame.

[0011] Preferably, baffles are fixedly connected to the front side wall and the two opposite side walls of the frame, and the baffles are used to ensure that the bubbles generated by the aeration pipe diffuse out from the rear opening of the frame.

[0012] Preferably, an integrated detector is fixedly connected to the front end of each of the two sets of frames. The integrated detector is used to detect the dissolved oxygen level in the water and to detect obstacles ahead.

[0013] Preferably, the air supply mechanism includes an air pump fixedly connected within the hull assembly, the air outlet of the air pump being connected to one end of an air pipe, and the other end of the air pipe being connected to a plurality of aeration pipes.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

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

[0027] Hull components,

[0028] Two sets of aeration components are symmetrically arranged on both sides of the hull component. The aeration components include an air supply mechanism installed in the hull component and an aeration mechanism installed below the hull component. The aeration mechanism is connected to the air supply mechanism and is used to generate bubbles underwater to achieve the aeration effect.

[0029] Two sets of thrust generating components are respectively located on both sides of the bottom of the hull component. Two sets of aeration mechanisms are respectively located inside the two sets of thrust generating components. An opening is provided at the end of the thrust generating component near the stern of the hull component, and the opening is used to diffuse the bubbles.

[0030] The main function of the hull assembly is to allow the mobile aerator to float on the water surface. The air supply mechanism supplies air to the aeration mechanism, which generates bubbles underwater to increase the contact area between water and air. The thrust generation assembly generates thrust by ejecting the bubbles generated by the aeration mechanism from the tail opening. By setting a thrust generation assembly on each side of the bottom of the hull assembly, the thrust generated by the thrust generation assembly can be controlled by controlling the operation of the air supply assembly, thereby controlling the direction of travel of the hull assembly. Overall, the hull assembly of this invention is powered directly by the air supply mechanism. The aeration mechanism generates bubbles underwater, increasing the contact area between air and water, achieving aeration while propelling the hull assembly forward and turning. This enables uniform oxygenation throughout the pond, simplifies the structure, reduces overall power consumption, and is superior to traditional propeller power. It also avoids entanglement with aquatic plants during travel, improving operational stability.

[0031] Further optimization of the design includes the installation of a battery (not shown in the figure) and a control unit (not shown in the figure) within the hull components. The battery provides electrical power, and the control unit is electrically connected to the gas supply mechanism.

[0032] Further optimization of the scheme: the thrust generating component includes a frame 1, which is horizontally fixedly connected to the bottom of the hull component. The aeration mechanism is set inside the frame 1, and the tail end of the frame 1 is provided with an opening for the rearward diffusion of bubbles.

[0033] like Figure 2 As shown, the frame 1 is a rectangular truss structure made of interconnected square steel bars, which is horizontally fixed to the bottom of the hull components and can reduce the resistance of the ship.

[0034] The scheme is further optimized. The aeration mechanism includes several aeration pipes 7, which are horizontally fixed to the bottom of the frame 1. The aeration pipes 7 are connected to the inside of the frame 1, and the aeration pipes 7 are respectively connected to the air supply mechanism.

[0035] like Figure 2 As shown, several aeration pipes 7 are horizontally fixed between two opposing 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] The design has been further optimized by wrapping the surface of the aeration pipe 7 with a sponge, which is used to generate dense bubbles underwater.

[0037] To further optimize the design, baffles 6 are fixedly connected to the front side wall and the two opposite side walls of the frame 1, respectively. The baffles 6 are used to ensure that the bubbles generated by the aeration pipe 7 diffuse out from the tail opening of the frame 1.

[0038] like Figure 2 As shown, the vertically arranged square steel of the frame 1 has slots (not shown in the figure), and the two ends of the three sets of baffles 6 are fixedly connected to the front end and two opposite sides of the frame 1 through the slots. Figure 5 As shown, the bubbles generated by the aeration pipe 7 inside the frame 1 are separated by the baffle 6 and move towards the opening at the rear of the frame 1. The aerator is self-propelled by the reverse thrust of the moving bubbles.

[0039] The scheme was further optimized by fixing an integrated detector 2 to the front end of each of the two sets of frames 1. The integrated detector 2 is used to detect the dissolved oxygen in the water and to detect obstacles in front.

[0040] like Figure 1 As shown, the integrated detector 2 consists of a dissolved oxygen meter and an infrared ranging sensor, which are fixedly integrated into the same housing. The integrated detector 2 is electrically connected to the control unit.

[0041] The solution is further optimized by electrically connecting the control unit to the integrated detector 2. The control unit can control the start and stop of the aerator and automatic cruise through the monitoring signal fed back by the integrated detector 2. The control unit also includes a remote control receiver module, which can support manual remote control.

[0042] Further optimization of the scheme: the air supply mechanism includes an air pump 3 fixedly connected in the hull component, the air outlet 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 several aeration pipes 7.

[0043] The air pipe 8 passes through the hull assembly and connects to one end of a connecting air pipe built into the square steel of the frame 1. The other end of the connecting air pipe is connected to several aeration pipes 7 via sockets. The built-in connecting air pipe can prevent the bubbles in the frame 1 from encountering obstacles when moving towards the stern.

[0044] Further optimization of the scheme: the hull assembly includes two sets of parallel hulls 5, which are fixedly connected by several crossbeams 9. Two sets of frames 1 are fixedly connected to the bottom of the two hulls 5 respectively, and two air pumps 3 are fixedly connected to the two hulls 5 respectively.

[0045] like Figure 1 The catamaran design shown allows the aerator's overall structure to be laid flat, effectively preventing capsizing and improving structural stability.

[0046] In a further optimized design, a solar panel 4 is installed between the two hulls 5. The solar panel 4 is fixedly connected to several crossbeams 9 and is used to provide power to the air pump 3.

[0047] 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 completes its self-test, it first uses the integrated detector 2 to determine if there is an obstacle in front of it. If there is no obstacle, it starts the two sets of air pumps 3.

[0049] During operation, the aerator continuously uses integrated detector 2 to first determine if there are any obstacles ahead, and then to assess the dissolved oxygen levels on both sides of the aerator. When there are no obstacles ahead, if integrated detector 2 detects a low dissolved oxygen level on the left, the control unit adjusts the voltage of the right air pump 3 based on the feedback signal, increasing the pumping volume of the right air pump 3 to achieve a left turn of the aerator. Similarly, if the dissolved oxygen level on the right is low, the voltage is adjusted to increase the pumping volume of the left air pump 3, achieving a left turn. When integrated detector 2 detects an obstacle ahead, the control unit first adjusts the voltage to reduce the pumping volume of both air pumps 3 to achieve deceleration, then integrated detector 2 assesses the dissolved oxygen levels on both sides, and repeats the above turning process, turning towards the direction with the lower dissolved oxygen level. Through the movement of the aerator on the water surface, uniform oxygenation is ultimately achieved throughout the pond.
