Description

Technical Field

[0001] This invention relates to the field of microbial agent delivery vessel equipment, and particularly to an automated microbial cultivation and addition device for constructed wetland construction. Background Technology

[0002] Constructed wetlands are artificially built and controlled wetland-like surfaces similar to marshes. Wastewater and sludge are systematically introduced onto these artificial wetlands, and the wastewater and sludge are treated through the synergistic physical, chemical, and biological processes of soil, artificial media, plants, and microorganisms during their directional flow. The mechanisms of action include adsorption, retention, filtration, oxidation-reduction, sedimentation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration of water and nutrients, and the activity of various animals. The cultivation and introduction of microorganisms is a crucial step. Existing systems require manual cultivation of microorganisms before release by boat onto the water. This process involves the cultivation, transfer, and release of microorganisms, which can lead to significant microbial death during transfer. Furthermore, manual release is often uneven and, due to the high frequency of releases, results in high labor intensity for personnel.

[0003] Chinese utility model patent CN208292740U discloses a microbial preparation dispensing vessel, comprising a hull and a microbial preparation dispensing device. The device includes multiple preparation storage tanks with movable partitions between adjacent tanks. Each storage tank is connected to a preparation delivery pipe near the stern. The device also includes a preparation mixing main pipe and a dispensing pipe. The advantages of this device are: it integrates mixing, loading, and dispensing; it automatically mixes different microbial strains in precise proportions; and it eliminates the need for manual dispensing, automatically dispensing while the vessel is in motion, thus saving manpower and resources. However, its disadvantages are: the device simply mixes without culturing the microorganisms, resulting in low microbial survival rates and poor effectiveness; and it does not evenly disperse the microorganisms in the water after dispensing, leading to uneven dispensing. Most importantly, the device requires manual operation, is bulky, inconvenient to maneuver, and cumbersome to operate. Summary of the Invention

The gear disk 218 intermittently meshes with the gear shaft 214. Multiple arc-shaped grooves are arranged in a circumferential array on the gear disk 218, and the center of each arc-shaped groove coincides with the center of the ball joint shaft 217. A sliding block 237 is fixedly connected to the gear disk 218. A threaded sliding groove 216 is provided on the outer wall of the ball joint shaft 217, and the threaded sliding groove 216 mates with the ball joint shaft 217. Multiple extrusion rods 221 are radially slidably connected to the ball joint shaft 217. The extrusion rods 221 slide in the arc-shaped grooves on the gear disk 218. Extrusion springs 222 are fixedly connected to the extrusion rods 221, and the extrusion springs 222 are fixedly connected to the ball joint shaft 217. A ball joint sealing frame 224 is fixedly connected to the delivery shaft 210. The sealing frame 224 and the ball joint shaft 217 form a ball joint connection. An elastic rubber ball 223 is fixedly connected to the delivery shaft 210. Multiple liquid supply holes are provided on the delivery shaft 210 in the area corresponding to the elastic rubber ball 223. Two one-way valves are provided on the delivery shaft 210, located at opposite ends of the elastic rubber ball 223. Two telescopic sections are provided on the delivery shaft 210, located between the ball head near connecting rod I 208 and the elastic rubber ball 223, and between the ball head near driven disc 234 and the elastic rubber ball 223, respectively. A directional motor I 204 and a directional motor II 206 are fixedly connected to the hull 101. A crank 232I is fixedly connected to the directional motor I 204, and a rotatable connection is made to the crank I 205. A crank 232Ⅱ is fixedly connected to connecting rod I 208 and directional motor II 206. A connecting rod II 209 is rotatably connected to crank II 207. Connecting rod I 208 and connecting rod II 209 are rotatably connected. The ball joint at one end of the delivery shaft 210 forms a ball joint connection with connecting rod I 208 and connecting rod II 209 respectively. Multiple circular array propeller shafts 231 are rotatably connected to the rotating drum 201. Adjusting connecting rods 235 and propellers 202 are fixedly connected to the propeller shafts 231. Two connecting cranks 232 are rotatably connected to the rotating drum 201. The connecting cranks 232 are rotatably connected to the adapter frame 233. A driven disk 234 is slidably connected to the adapter frame 233. Multiple circular array adjusting columns 236 are fixedly connected to the side of the driven disk 234 away from the adapter frame 233.Adjusting connecting rod 235 and adjusting column 236 are fitted together; the ball head at one end of the release shaft 210 is connected to the driven disc 234 in a ball joint connection; adjusting bracket 219 is fixedly connected to the hull 101, hydraulic pipe II 226 is fixedly connected to the adjusting bracket 219, telescopic rod IV 227 is slidably connected to the hydraulic pipe II 226, adjusting rod 220 is slidably connected to the telescopic rod IV 227, gear shaft 214 is rotatably connected to the adjusting rod 220, compression spring II 230 and compression spring I 229 are fixedly connected to the telescopic rod IV 227, compression spring I 229 and compression spring II 230 are fixedly connected to the adjusting rod 220, and compression spring I 229 is fixedly connected to the telescopic rod IV 227. 9. On the outside of the adjusting rod 220, the compression spring II 230 is on the inside of the adjusting rod 220. The other end of the hydraulic pipe II 226 is slidably connected to the telescopic rod I, and the telescopic rod I is in contact with one end face of the gear plate 218. The hull 101 is fixedly connected to the hydraulic pipe I 225. One end of the hydraulic pipe I 225 is slidably connected to the telescopic rod II. The telescopic rod II and the telescopic rod IV 227 are in cooperation. The other end of the hydraulic pipe I 225 is slidably connected to the telescopic rod III, and the telescopic rod III is in contact with the other end face of the gear plate 218. The adjusting bracket 219 is slidably connected to the trigger rod 228. The trigger spring is fixedly connected to the adjusting bracket 219. The ball joint near connecting rod I 208 on the delivery shaft 210 is designated as the upper ball joint, and the ball joint near driven disc 234 is designated as the lower ball joint. The position of the upper ball joint is controlled by the combined action of directional motor I 204 and directional motor II 206. A change in the position of the upper ball joint causes the delivery shaft 210 to rotate around the ball joint seal 224, thereby changing the position of the lower ball joint. The displacement of the lower ball joint drives the driven disc 234 to move. During the deflection of the delivery shaft 210, both telescopic sections on the delivery shaft 210 extend to compensate for the length difference caused by the deflection. When the delivery shaft 210 is in a vertical state, both telescopic sections on the delivery shaft 210 are in a retracted state. When the driven disc 234 moves with the deflection of the delivery shaft 210, the two connecting cranks 232 and the adapter frame 233 move synchronously for adjustment. At the same time, the displacement of the driven disc 234 causes the corresponding adjustment... The spur column 236 drives the adjusting connecting rod 235, causing the propeller shaft 231 to deflect. If the main motor 203 is started at this time, the bevel gear I 211 will drive the bevel gear ring 215. The bevel gear ring 215 causes the rotating drum 201 to rotate through the ball joint shaft 217. In water, the propeller 202 is fixedly connected to the propeller shaft 231. On land, the roller is fixedly connected to the propeller shaft 231. Since the rotation of the rotating drum 201 will cause the propeller shaft 231 to revolve, and the propeller shaft 231 has deflected beforehand, the rotation of the rotating drum 201 will cause the hull 101 to move through the propeller 202 or the roller. The direction of deflection of the launch shaft 210 can be controlled by the directional motor I 204 and the directional motor II 206, thereby controlling the forward, backward, left, and right displacement of the hull 101. If the launch shaft 210 does not deflect (i.e., in a vertical state), the hull 101 will not move when the rotating drum 201 rotates.It simply maintains its original position. When the gear shaft 214 meshes with the gear disk 218, during the rotation of the ball joint shaft 217, the gear shaft 214 causes the gear disk 218 to rotate, and the rotation direction of the gear disk 218 is the same as that of the ball joint shaft 217, but the rotation speed of the gear disk 218 is slightly faster than that of the ball joint shaft 217. At this time, the gear disk 218 rotates relative to the threaded groove 216, so the groove block 237 on the gear disk 218 will slide on the threaded groove 216, and the gear disk 218 will gradually rise. As the gear disk 218 rotates, the compression spring 222 is compressed, and the compression rod 221 compresses the elastic rubber ball 223. After the elastic rubber ball 223 is compressed, the liquid containing microorganisms stored in it will be discharged through the lower ball head. Upon exiting the water, the elastic rubber ball 223 is slowly and uniformly compressed by the compression rod 221, causing the liquid containing microorganisms in the elastic rubber ball 223 to be evenly discharged into the water. Simultaneously, the rotation of the paddle 202 driven by the rotating drum 201 causes the discharged microorganisms to spread rapidly and evenly. Returning to the step where the gear disc 218 rotates and moves upward, the upward movement of the gear disc 218 causes the telescopic rod I on the hydraulic pipe II 226 to retract, while the telescopic rod IV 227 extends. When the telescopic rod IV 227 extends, because the adjusting rod 220 is blocked by the trigger rod 228, the compression spring II 230 is compressed and the compression spring I 229 is stretched. The telescopic rod IV 227 then pushes the telescopic rod II, causing the telescopic rod III to extend upward. When the gear disc 218 moves upward a certain height, the combined force of the compression spring II 230 and the tension of the compression spring I 229 exceeds the force of the trigger spring on the trigger rod 228. At this point, the trigger rod 228 is completely compressed back into the adjusting bracket 219. The adjusting rod 220 then moves under the action of the compression springs II 230 and I 229. This displacement of the adjusting rod 220 causes the gear shaft 214 to slide. The gear shaft 214 then disengages from the gear disc 218, meaning the gear disc 218 is no longer driven by the gear shaft 214. Under the action of the compression spring 222, the compression rod 221 extends and resets. After the compression rod 221 moves away from the elastic rubber ball 223, the elastic rubber ball 223 automatically returns to its spherical shape. At this time, the elastic rubber ball 223 can draw the microbial liquid cultured in the incubator 104 into the elastic rubber ball 223 for storage through the liquid supply through hole on the feeding shaft 210. The extension of the squeezing rod 221 causes the toothed disc 218 to rotate in the opposite direction and move downward relative to the ball receiving shaft 217. Similarly, when the toothed disc 218 has completely moved downward and reset, the adjusting rod 220 slides in the opposite direction, causing the gear shaft 214 to mesh with the toothed disc 218 again. During this process, the squeezing process of the squeezing rod 221 on the elastic rubber ball 223 is relatively slow, but the reset process of the squeezing rod 221 is relatively rapid. Therefore, the absorption process of the elastic rubber ball 223 will not delay the feeding process of the elastic rubber ball 223.

[0035] like Figures 11-12As shown, the culture assembly 3 includes a movable support 303, which is rotatably connected to the incubator 104. A calibration plate 301 is fixedly connected to the movable support 303. A stirring shaft 309 is rotatably connected to the movable support 303. Multiple stirring rods 310 are fixedly connected to one end of the stirring shaft 309 near the incubator 104, and a bevel gear IV 304 is fixedly connected to the other end of the stirring shaft 309 away from the incubator 104. Two bevel gears VI 307 are fixedly connected to the movable support 303. A connecting shaft 306 is rotatably connected to the movable support 303, and a bevel gear V 305 is fixedly connected to the connecting shaft 306. The bevel gear V 305 and the bevel gear IV... 304 meshes with a bevel gear VII 308 rotatably connected to both ends of the connecting shaft 306. A fan blade 302 is fixedly connected to the bevel gear VII 308, and the bevel gear VII 308 meshes with the bevel gear VI 307 on the same side. The stirring rod 310 is a heating rod. An oxygen generator is installed on the hull 101, and the stirring rod 310 is connected to the oxygen generator. The oxygen generated by the oxygen generator is distributed to the incubator 104 through the stirring rod 310. The end of the incubator 104 away from the calibration plate 301 is fixedly connected to a hose 311, and the incubator 104 is provided with a retention tank 312 so that when the microorganisms in the incubator 104 are discharged through the hose 311, they are not completely discharged. The two fan blades 302 are always perpendicular to each other. When the hull 101 moves forward or stops but there is wind, the calibration plate 301 is used to calibrate the direction of the wind, so that the two fan blades 302 face the wind. At this time, the two fan blades 302 work together, and under the wind force, the connecting shaft 306 rotates. The directional motor II 206 rotates, which in turn rotates the stirring shaft 309. When the stirring shaft 309 rotates, it stirs the distribution of microorganisms in the liquid in the incubator 104 evenly through the stirring rod 310. At the same time, the heating effect of the stirring rod 310 is used to maintain a suitable temperature of the liquid in the incubator 104 and to ensure that all parts are heated. With a reasonable temperature difference, the oxygen released by the stirring rod 310 can also be evenly distributed in all parts of the liquid, ensuring uniform oxygen supply to all microorganisms. When the liquid containing microorganisms in the incubator 104 is discharged through the hose 311, a portion of microorganisms will always remain in the retention tank 312. The purpose of this setting is to preserve the inoculum, meaning that only water and nutrients in the correct proportion need to be added later for further cultivation, without the need to add microorganisms again. The surface of the fan blade 302 is coated with reflective material, which can reflect light during the movement of the fan blade 302, preventing birds from landing on the device and effectively preventing birds from nesting and other activities.

[0036] Working Principle: On land, rollers are installed on the propeller shaft 231. At this time, the incubator 104 is empty of water and nutrients. Controlling the rotation of the rotating drum 201, combined with the movement of directional motors I 204 and II 206, controls the movement of the hull 101. After the hull 101 is launched into the water, the rollers are replaced with the propeller 202. Water from the water tank 102 and nutrients from the nutrient tank 103 are then pumped into the incubator 104 via a pump. The required microorganisms are then added. The device is then kept on the water surface, and wind power drives the fan blades 302 to rotate the stirring shaft 309. The stirring rod 310 begins mixing the microorganisms and nutrients, while simultaneously regulating the temperature and supplying oxygen, providing favorable conditions for the growth and reproduction of microorganisms. As long as there is wind, the stirring rod 310 will continuously stir to achieve uniform temperature control and oxygen supply. When the microbial culture is complete, the movement of the directional motor I 204 is controlled. The directional motor II 206 controls the deflection of the dispensing shaft 210, and simultaneously starts the main motor 203, causing the rotating drum 201 to rotate. At this time, the hull 101 begins to move. During the movement of the hull 101, the elastic rubber ball 223 will absorb the liquid containing microorganisms in the incubation tank 104, and then evenly dispense the material through the lower ball head. At the same time, the paddle 202 will disperse the dispensed microorganisms and accelerate their diffusion speed. When the microorganisms cultivated in the incubation tank 104 are completely discharged, only the microorganisms in the retention tank 312 remain. At this time, the main motor 203 stops, and the materials in the water tank 102 and the nutrient tank 103 are pumped back into the incubation tank 104 to start the next round of cultivation. This process is repeated until the water and nutrients stored in the water tank 102 and the nutrient tank 103 are used up. After that, the hull 101 returns to shore to replenish water and nutrients and can start the next round of dispensing. The whole process does not require personnel to follow.
