DETAILED DESCRIPTION

[0016] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0017] like Figures 1 to 5As shown, the present invention provides an air distribution device for aerobic fermentation of river and lake bottom mud, comprising a buoyancy box 1 on the upper side, an arc-shaped tube 2 is arranged on the lower side of the buoyancy box, both ends of the arc-shaped tube are facing downward, an arc-shaped groove 3 adapted to the shape of the arc-shaped tube is arranged at the bottom of the buoyancy box 1, junction boxes 4 are fixedly arranged on both sides of the arc-shaped tube, winding wheels 5 are arranged corresponding to the junction boxes on both sides of the buoyancy box, a sleeve 6 is wound around the winding wheel, and the lower end of the sleeve 6 is fixedly connected to the corresponding junction box, a pushing plate 7 is arranged in the arc-shaped tube 2, and the pushing plate is fixedly connected to one end of the arc-shaped tube by a spring 8, and the pushing plate can move to the other end of the arc-shaped tube under the pushing action of the spring 8, and a plurality of stacked hollow plates 9 are arranged between the pushing plate and the other end of the arc-shaped tube, and the plate surface of the hollow plate is opened Multiple fine holes, the connected hollow plates 9 are connected by an elastic tube 10, an outlet 11 is opened on the lower side of the other end of the arc tube, and a pneumatic telescopic rod 12 is arranged on the upper side of the other end of the arc tube. The telescopic end of the pneumatic telescopic rod extends into the interior of the arc tube and is located at the upper end of the hollow plate closest to the other end of the arc tube. The hollow plate fitted with the push plate 7 is connected to one end of the first connecting tube 13, and the other end of the first connecting tube 13 passes through the junction box and the sleeve 6 and extends into the buoyancy tank and is connected to the first air pump in the buoyancy tank. The air intake of the first air pump is connected to the heater, and the cylinder of the pneumatic telescopic rod is connected to one end of the second connecting tube 15, and the other end of the second connecting tube 15 passes through the junction box and the sleeve 6 and extends into the buoyancy tank and is connected to the second air pump in the buoyancy tank.

[0018] The operation of the second air pump can control the extension and retraction of the pneumatic telescopic rod. This is the prior art and will not be elaborated here. The operation of the second air pump controls the extension of the telescopic end of the pneumatic telescopic rod, and the telescopic end can push out the hollow plate closest to the other end of the arc tube through the outlet 11. After the hollow plate is pushed out, under the action of the spring and the push plate, the next hollow plate moves to the position of the outlet 11.

[0019] Slide plates 16 are fixedly mounted on both ends of the arc tube. This design allows the arc plate to move more smoothly on the bottom mud surface, reducing resistance.

[0020] Guide plates 17 are provided on both sides of the outlet 11. The design of the guide plates can make the hollow plate move out of the outlet more smoothly and avoid skewing when moving out.

[0021] The cross-section of the arc-shaped plate is preferably rectangular, and the hollow plate is also rectangular. The upper end of the hollow plate is provided with a groove 18 that matches the telescopic end of the pneumatic telescopic rod.

[0022] A controller and a storage battery are arranged in the buoyancy box, and the heater, the first air pump and the second air pump are all connected with the controller and the storage battery.

[0023] A lifting handle 14 is provided on the upper part of the buoyancy box, and this design makes it convenient for the user to move the device.

[0024] Working principle: The user puts the device into the water, and can use the boat to pull the device forward at a constant speed in the water, and lower the arc tube to the bottom mud surface through the reel 5. Figure 5 As shown, at this time, a part of the buoyancy box is located above the water level. While the buoyancy box moves at a uniform speed, it drives the arc tube to move at a uniform speed through the casing. At this time, the controller controls the second air pump to work, controls the telescopic end of the pneumatic telescopic rod to extend, and pushes out the hollow plate closest to the other end of the arc tube through the outlet 11 and inserts it into the bottom mud. After pushing out the hollow plate, the telescopic end of the pneumatic telescopic rod retracts, and under the action of the spring and the push plate, the next hollow plate moves to the position of the outlet 11. Repeating the above process can insert multiple hollow plates into the bottom mud in sequence at a certain distance. When all the hollow plates are inserted into the bottom mud, the buoyancy box is placed in this position to float freely. The arc tube has a certain weight, which can keep the buoyancy box in this area. The controller controls the first air pump to work, pumps air into the hollow plate through the first connecting pipe, and the air heated by the heater is slowly discharged through the pores of the hollow plate to increase ventilation for the bottom mud.

[0025] The design of this device can quickly arrange evenly set hollow plates in the bottom mud, set the speed quickly and evenly, and has the advantages of being small and flexible compared to traditional equipment. It can also be recycled and reused, promote the growth and reproduction of aerobic microorganisms, ensure the progress of aerobic fermentation, increase the temperature of the bottom mud, and can adjust the temperature of the bottom mud to ensure that the microorganisms maintain normal vitality.

[0026] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
