Description

Technical Field

[0001] This invention relates to the field of water pollution control technology, and in particular to a device for dispensing microbial carriers for river and lake water treatment and its usage method. Background Technology

[0002] In river and lake wastewater treatment, microorganisms possess characteristics such as rapid reproduction, strong vitality, and safety without toxicity. Microbial bacteria multiply by consuming organic pollutants in the water, thus achieving a good removal effect on organic pollutants in wastewater. Microorganisms are widely used in wastewater treatment; microbial agents are used to degrade pollutants in wastewater, thereby achieving the purpose of wastewater treatment. When adding microorganisms to wastewater, microbial dosing devices are frequently used.

[0003] In the prior art, such as the utility model patent with announcement number "CN223357491U", a "microbial dispensing device for water body ecological restoration" is disclosed. This device sprays microorganisms onto the water surface through the nozzle on the first feeder, which can expand the dispensing range of microorganisms and improve the efficiency of water body ecological restoration by microorganisms.

[0004] However, the device can only spray the microbial mixture onto the surface of the water body and cannot deliver the mixture to the middle and bottom layers of the water. Organic pollutants in rivers and lakes often exhibit vertical stratification, and pollutants in the bottom sediments and deep water layers cannot be effectively degraded, resulting in a long overall treatment cycle, unstable effects, and even the problem of surface water quality meeting standards while deep pollution persists. Summary of the Invention

[0005] To overcome the above deficiencies, the present invention provides a device for dispensing microbial carriers for river and lake water treatment and a method for using it, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device for dispensing microbial carriers for river and lake water treatment, comprising:

[0007] A launch vessel hull, wherein a launch storage box is fixedly connected to the inner bottom wall of the launch vessel hull;

[0008] A delivery mechanism is installed inside a delivery storage box, with a portion of the delivery mechanism located inside the delivery vessel hull and another portion extending to the outside of the delivery vessel hull.

[0009] The dispensing mechanism includes a quantitative dispensing component, a depth dispensing component, and a control dispensing component. The quantitative dispensing component is installed inside the dispensing storage tank, with one end extending into the interior of the dispensing vessel. The outlet end of the quantitative dispensing component is sealed and connected to the depth dispensing component. The depth dispensing component is located outside the dispensing vessel, installed on the side of the dispensing vessel near the dispensing storage tank. The upper end of the external vertical frame of the depth dispensing component is fixedly connected to the rotating sleeve of the control dispensing component, forming a transmission engagement. The control dispensing component is installed on one side of the dispensing vessel.

[0010] Furthermore, the depth delivery component includes a conduit fixedly connected to one side of the delivery vessel hull. The end of the conduit passes through the delivery vessel hull and extends into the interior of the delivery storage box. Several rubber rings are fixedly connected to the surface of the conduit. An outer ring is rotatably connected to the conduit between adjacent rubber rings. An inner connecting pipe communicating with the outer ring is fixedly connected to the lower end of the outer ring. A connecting frame is fitted on the inner connecting pipe. An outer extension pipe is fixedly connected to the connecting frame. The inner wall of the outer extension pipe is slidably connected to the inner connecting pipe.

[0011] Furthermore, the control and release assembly includes two mounting plates fixedly connected to the release vessel hull. A connecting rod is fixedly connected to the mounting plate, and a central shaft is fixedly connected to the other end of the connecting rod. A threaded rotating rod is provided above the connecting rod and is rotatably connected to the mounting plate. A crankshaft is provided between the two threaded rotating rods, and a threaded sleeve is fixedly connected to the end of the crankshaft. The threaded sleeve is threadedly connected to the threaded rotating rod.

[0012] Furthermore, the quantitative dispensing assembly includes an electric push rod disposed inside the dispensing vessel. The telescopic end of the electric push rod extends into the interior of the dispensing storage box and is fixedly connected to an end connecting pipe. An inner tube is sleeved on the outside of the end connecting pipe, and the inner tube is disposed inside the dispensing storage box. A connecting piston is slidably connected to the surface of the end connecting pipe, and the connecting piston is slidably connected to the inner wall of the inner tube. A cup piston is fixedly connected to the end of the inner tube near the electric push rod. The lip of the cup piston faces away from the electric push rod and slides and seals with the outer wall of the end connecting pipe to form a one-way backflow blocking sealing structure.

[0013] Furthermore, a depth vertical plate is fixedly connected to the upper end of the connecting frame, and an external vertical frame is slidably connected to the surface of the depth vertical plate. The external vertical frame is fixedly connected to the control and dispensing component. Multiple positioning holes are provided on the depth vertical plate, and positioning pins are inserted into the inner walls of the positioning holes. The ends of the positioning pins extend to the outside of the external vertical frame.

[0014] Furthermore, the surface of the central shaft is provided with a plurality of first annular grooves, and a rotating sleeve is rotatably connected to the first annular groove. The lower end of the rotating sleeve is fixedly connected to the depth delivery component, and the upper end of the rotating sleeve is fixedly connected to an adjustment frame.

[0015] Furthermore, the surface of the crankshaft is provided with a plurality of second annular grooves, which are arranged along the crankshaft axial direction and have differentiated eccentric heights in the radial direction of the crankshaft. The inner wall of the second annular groove slides in fit with the inner wall of the control frame.

[0016] Furthermore, the end of the end connecting pipe near the electric push rod has an inlet hole, and a rubber plug is fixedly connected inside the end connecting pipe. An installation screen is provided on the side of the rubber plug away from the electric push rod, and the installation screen is fixedly connected inside the end connecting pipe.

[0017] Furthermore, a spring is fixedly connected to one side of the mounting screen, and a blocking ball is fixedly connected to the other end of the spring, with the blocking ball abutting against the rubber block.

[0018] A method for using a microbial carrier delivery device for river and lake water treatment includes the following steps:

[0019] Step S1: Based on the pollution level, water depth, and treatment requirements of the target river and lake area, prepare a microbial carrier mixture of corresponding concentration and inject the mixture into the release storage tank inside the release vessel; check the pipeline sealing performance, sliding fit accuracy, and transmission connection reliability of the release mechanism; reset each component to its initial state and then drive the release vessel to the preset release point in the target treatment area.

[0020] Step S2: Based on the vertical water depth of the target water area and the requirements for pollution stratification treatment, pull the depth vertical plate to slide along the external vertical frame. Through the connecting frame, drive the external extension pipe to slide synchronously along the outer wall of the internal connecting pipe to adjust the vertical deployment depth of the external extension pipe outlet. After the depth is adjusted to the target position, insert the positioning pin into the corresponding positioning hole on the depth vertical plate and make the end of the positioning pin pass through the external vertical frame to complete the mechanical locking of the deployment depth.

[0021] Step S3: Rotate the threaded rotating rod of the control and dispensing component. Through threaded transmission, drive the threaded sleeve to move axially along the threaded rotating rod, thereby driving the crankshaft to make horizontal linear displacement. During the horizontal displacement of the crankshaft, the second annular grooves arranged axially and having different radial eccentric heights on its surface can simultaneously drive multiple sets of control frames to form different tilt angles. The control frames drive the rotating sleeve to rotate along the first annular groove on the central shaft surface, thereby driving multiple sets of depth dispensing components to form different dispensing tilt angles through the external vertical frame, constructing a three-dimensional dispensing layout with multiple water depths and multiple points. At the same time, the outer ring rotates synchronously around the guide tube with the internal connecting pipe. The rubber ring on the surface of the guide tube forms a dynamic seal during the rotation of the outer ring, ensuring that there is no leakage or pressure drop during the mixed liquid transportation process.

[0022] Step S4: Activate the electric push rod of the quantitative dispensing component, driving the end connecting tube to move the connecting piston in a reciprocating linear motion on the inner wall of the inner tube, completing the entire cycle of a single quantitative dispensing:

[0023] Step S41, Suction Stroke: The electric push rod drives the connecting piston to move closer to the electric push rod, creating a negative pressure in the cavity of the internal tube. The piston cup forms a one-way seal to block the backflow of the mixture. The mixture in the storage tank enters the tube through the liquid inlet of the end connecting tube, pushing the sealing ball to compress the spring and open the flow channel. The mixture is continuously injected into the cavity of the internal tube to complete the liquid injection.

[0024] Step S42, Pushing stroke: The electric push rod drives the connecting piston to move away from the electric push rod. The spring rebounds and causes the sealing ball to abut against the rubber plug to form an end face seal. The connecting piston pushes a metered amount of mixed liquid in the cavity to be transported to the outer ring through the conduit, and then through the inner connecting tube and the outer extension tube in sequence, to be accurately delivered to the preset depth and position of the target water body.

[0025] Step S5: Drive the deployment vessel to travel at a constant speed along the preset treatment route. During the journey, steps S2-S4 can be repeated to dynamically adjust the deployment depth, tilt angle and single deployment amount to complete the uniform deployment of microbial carriers throughout the target water area. After the deployment of the entire water area is completed, turn off the electric push rod, reset the external extension pipe and the control deployment component to the initial position, and use clean water to rinse and maintain the deployment pipeline and components.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In this invention, the sliding and telescopic structure of the internal connecting pipe and the external extension pipe in the depth delivery component allows for flexible adjustment of the delivery depth, adapting to the layered delivery needs of the surface, middle, and bottom layers of water bodies. Simultaneously, with the adjustable angle of the delivery component, multiple sets of delivery pipes at different depths and angles can be simultaneously deployed, constructing a three-dimensional delivery network. This ensures that the microbial carrier mixture is evenly distributed in water bodies of varying depths, solving the problem in existing technologies where the microbial carrier mixture cannot be delivered to different water depths, thus significantly improving the effectiveness and efficiency of river and lake management.

[0028] 2. In this invention, the electric push rod of the quantitative dosing component drives the piston to reciprocate, and in conjunction with the one-way anti-backflow structure of the cup piston, and the one-way valve structure composed of the sealing ball, spring and rubber block, the precise control of the dosing amount per dosing can be achieved. The dosing amount can be flexibly adjusted according to the degree of water pollution and the volume of the water body, avoiding the problems of waste and insufficient dosing of the microbial carrier mixture, and the treatment cost is controllable and the effect is stable.

[0029] 3. In this invention, the tilt angle of multiple sets of delivery tubes can be adjusted synchronously through the transmission structure of the crankshaft and the control frame, and the differentiated angle settings of multiple sets of delivery tubes can be realized. Combined with the movement of the delivery vessel, it can be adapted to rivers and lakes of different widths and shapes, completely eliminating delivery blind spots and greatly improving the efficiency of large-area water management operations.

[0039] 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.

[0040] Example 1

[0041] Reference Figure 1-8 The embodiment provides a microbial carrier delivery device for river and lake water treatment, comprising three main components: a delivery vessel 100, a delivery storage box 200, and a delivery mechanism 300.

[0042] The launch vessel 100 is an unmanned or manned vessel capable of autonomous navigation on river or lake surfaces, providing a mobile carrier and installation foundation for the entire device. The inner bottom wall of the launch vessel 100 is bolted to a launch storage tank 200, which is a sealed tank structure used to store the prepared microbial carrier mixture. The launch storage tank 200 is equipped with a launch mechanism 300, the core function of which is to realize the quantitative delivery, depth adjustment, and angle control of the microbial carrier mixture. Part of the launch mechanism 300 is located inside the launch vessel 100, and another part extends to the outside of the launch vessel 100.

[0043] like Figure 2As shown, the dispensing mechanism 300 includes a quantitative dispensing component 330, a depth dispensing component 320, and a regulating dispensing component 310. The quantitative dispensing component 330 is installed inside the dispensing storage tank 200, and its drive end extends into the dispensing hull 100. The liquid outlet of the quantitative dispensing component 330 is sealed and connected to the liquid inlet of the depth dispensing component 320, for accurately and quantitatively dispensing the microbial carrier mixture to the depth dispensing component 320. The depth dispensing component 320 is entirely disposed outside the dispensing hull 100, and is installed on the side wall of the dispensing hull 100 near the dispensing storage tank 200. The upper end of the external vertical frame 327 of the depth dispensing component 320 is fixedly connected to the rotating sleeve 318 of the regulating dispensing component 310 and forms a transmission engagement, for realizing the vertical dispensing depth adjustment of the microbial carrier mixture. The regulating dispensing component 310 is fixedly installed on the side wall of the dispensing hull 100, for adjusting the dispensing tilt angle of multiple sets of depth dispensing components 320.

[0044] like Figure 3 and Figure 5 As shown, the depth dispensing component 320 includes a conduit 321 horizontally fixedly connected to the side wall of the dispensing hull 100. The conduit 321 is a rigid stainless steel pipe. The water inlet end of the conduit 321 penetrates the dispensing hull 100 and extends into the interior of the dispensing storage tank 200, and is sealed and connected to the liquid outlet end of the quantitative dispensing component 330. A plurality of rubber rings 322 are fixedly sleeved on the surface of the water outlet end of the conduit 321. An outer ring 323 is rotatably connected to the outer wall of the conduit 321 between two adjacent rubber rings 322. The outer diameter of the rubber ring 322 is interference-fitted with the inner diameter of the outer ring 323. When the outer ring 323 rotates around the conduit 321... A reliable dynamic seal is formed to completely prevent leakage of the mixed liquid; the lower end of the outer ring 323 is integrally formed with a connection port, and the connection port is fixedly connected to an internal connecting pipe 3210 that communicates with the inside of the outer ring 323. An external extension pipe 324 is sleeved on the outer wall of the internal connecting pipe 3210. The outer wall of the external extension pipe 324 is fixedly connected to the connecting frame 325 by bolts. The inner wall of the external extension pipe 324 is slidably sealed to the outer wall of the internal connecting pipe 3210. By sliding the external extension pipe 324 along the axial direction of the internal connecting pipe 3210, the total length of the entire injection pipeline can be adjusted, thereby adjusting the vertical injection depth of the outlet.

[0045] A depth vertical plate 326 is welded and fixed to the upper end of the connecting frame 325. An external vertical frame 327 is slidably connected to the surface of the depth vertical plate 326. The upper end of the external vertical frame 327 is fixedly connected to the lower end of the rotating sleeve 318 of the control and dispensing component 310. The depth vertical plate 326 has multiple positioning holes 329 evenly spaced along the axial direction. Positioning pins 328 are inserted into the inner wall of the positioning holes 329. The end of the positioning pin 328 extends through to the outside of the external vertical frame 327. By inserting the positioning pin 328 into different positioning holes 329, the relative position of the depth vertical plate 326 and the external vertical frame 327 can be locked, thereby locking the extension length of the external extension tube 324 and completing the precise fixing of the dispensing depth.

[0046] like Figure 4 and Figure 6 As shown, the control and release assembly 310 includes two parallel mounting plates 311 fixedly connected to the side wall of the release hull 100. A central shaft 313 is fixedly connected to the lower part between the two mounting plates 311 via a connecting rod 312. The central shaft 313 is arranged parallel to the guide tube 321. A threaded rotating rod 314 is provided above the connecting rod 312. One end of the threaded rotating rod 314 is rotatably connected to the two mounting plates 311 via a bearing. A crankshaft 315 is provided between the two threaded rotating rods 314. Threaded sleeves 316 are welded and fixed to both ends of the crankshaft 315. The two threaded sleeves 316 are respectively threadedly connected to the surfaces of the two threaded rotating rods 314. By rotating the threaded rotating rod 314, the threaded sleeves 316 can be driven to move axially via threaded transmission, thereby driving the crankshaft 315 to make horizontal displacement.

[0047] The surface of the central shaft 313 is provided with multiple first annular grooves 317. A rotating sleeve 318 is rotatably connected to the inner wall of each first annular groove 317. The lower end of the rotating sleeve 318 is welded and fixed to the upper end of the outer vertical frame 327, and an adjusting frame 319 is welded and fixed to the upper end of the rotating sleeve 318. The surface of the crankshaft 315 is provided with multiple second annular grooves 3110. The multiple second annular grooves 3110 are arranged sequentially along the axial direction of the crankshaft 315, and the central axis of each second annular groove 3110 is radially aligned with the central axis of the crankshaft 315 itself. The upper part has a differentiated eccentric distance, forming a high and low differentiated arrangement structure. The inner wall of each second ring groove 3110 is slidably connected to the upper inner wall of the corresponding control frame 319. When the crankshaft 315 is horizontally displaced, the second ring grooves 3110 with different radial eccentric heights drive multiple sets of control frames 319 to form differentiated tilt angles, thereby driving the rotating sleeve 318 to rotate around the central axis 313, and finally driving multiple sets of depth delivery components 320 to form different delivery tilt angles, realizing multi-point, differentiated three-dimensional delivery.

[0048] like Figure 3 and Figure 7As shown, the quantitative dispensing component 330 includes an electric push rod 331 fixedly installed inside the dispensing hull 100. The cylinder of the electric push rod 331 is fixedly connected to the outer wall of the dispensing storage tank 200 via a bracket. The telescopic end of the electric push rod 331 penetrates the side wall of the dispensing storage tank 200 and extends into its interior. An end connecting pipe 332 is fixedly connected to the end of the telescopic end. An inner pipe 334 is coaxially sleeved on the outside of the end connecting pipe 332. The inner pipe 334 is entirely located inside the dispensing storage tank 200. The water outlet end of the inner pipe 334 is sealed and fixedly connected to the water inlet end of the conduit 321. A connecting piston 333 is slidably connected to the outer wall of the end connecting pipe 332. The outer wall of the connecting piston 333 is connected to the inner pipe 334. The inner wall of tube 34 is connected in a sliding seal. A cup piston 335 is fixedly connected to the inner wall of the inner tube 334 near the electric push rod 331. The inner wall of the cup piston 335 is slidably sealed to the outer wall of the end connecting tube 332. The lip of the cup piston 335 faces away from the electric push rod 331, forming a one-way anti-backflow structure. During the suction stroke of the connecting piston 333, the lip of the cup piston 335 is tightly fitted with the outer wall of the end connecting tube 332 to form a seal, blocking the backflow of the mixture. During the pushing stroke, the pressure of the mixture can further enhance the sealing effect of the lip, ensuring the stability of quantitative pushing. This ensures that the mixture can only enter the inner tube 334 from the dispensing storage box 200 and cannot flow back in reverse.

[0049] like Figure 8 As shown, the end connecting pipe 332 has an inlet hole 3320 on the side wall near the electric push rod 331, which is used to allow the mixed liquid in the storage tank 200 to enter the end connecting pipe 332. A rubber plug 337 is fixedly connected inside the end connecting pipe 332. A flow hole is opened in the center of the rubber plug 337. An installation screen 336 is provided on the side of the rubber plug 337 away from the electric push rod 331. The installation screen 336 is a porous stainless steel plate and is welded and fixed to the inner wall of the end connecting pipe 332. A spring 339 is fixedly connected to the side of the installation screen 336 facing the rubber plug 337. A sealing ball 338 is fixedly connected to the other end of the spring 339. The diameter of the sealing ball 338 is larger than the diameter of the flow hole in the center of the rubber plug 337. Under the elastic force of the spring 339, the sealing ball 338 abuts against the surface of the rubber plug 337 to form a one-way sealing structure, realizing closed-loop control of quantitative suction and pushing.

[0050] Example 2

[0051] This embodiment discloses a method for using a microbial carrier delivery device for river and lake water treatment, which is based on the microbial carrier delivery device for river and lake water treatment in Embodiment 1, and specifically includes the following steps:

[0052] Step S1, Preparation before deployment: First, conduct an on-site survey of the target river or lake area to detect parameters such as the degree of water pollution, COD concentration, water depth, and width of the water area. Based on the survey results, prepare a microbial carrier mixture with the corresponding concentration and dosage, and inject the mixture into the deployment storage tank 200 inside the deployment vessel 100. Then, check the pipeline sealing performance of the deployment mechanism 300, the sliding fit accuracy between the external extension pipe 324 and the internal connecting pipe 3210, and adjust the transmission connection reliability of the deployment component 310. Reset each component to its initial state (the external extension pipe 324 is fully retracted, and the deployment pipeline is perpendicular to the water surface). Finally, drive the deployment vessel 100 to the preset deployment point in the target water area and complete the vessel anchoring and fixing.

[0053] Step S2, Precise Adjustment of Vertical Deployment Depth: Based on the vertical water depth of the target water area and the requirements for stratified pollution treatment, if the bottom layer of the water body is severely polluted, the extension length of the external extension pipe 324 is increased; if the surface layer of the water body is severely polluted, the extension length is shortened. In specific operation, pull out the positioning pin 328, pull the depth vertical plate 326 to slide axially along the external vertical frame 327, and drive the external extension pipe 324 to slide synchronously along the outer wall of the internal connecting pipe 3210 through the connecting frame 325 to adjust the vertical deployment depth of the outlet of the external extension pipe 324. After the depth is adjusted to the target position, insert the positioning pin 328 into the corresponding positioning hole 329 on the depth vertical plate 326, and make the end of the positioning pin 328 penetrate through the external vertical frame 327 to complete the mechanical locking of the deployment depth. For multiple deployment pipes, differentiated extension lengths can be set to correspond to the surface, middle and bottom layers of the water body, respectively, to achieve synchronous stratified deployment.

[0054] Step S3, Differentiated Adjustment of Dispensing Angle: Rotate the threaded rotating rod 314 of the adjusting dispensing component 310, which drives the threaded sleeve 316 to move axially along the threaded rotating rod 314 through threaded transmission, thereby driving the crankshaft 315 to make horizontal linear displacement; during the horizontal displacement of the crankshaft 315, the second annular grooves 3110 arranged axially and having radially differentiated eccentric heights on its surface can simultaneously drive multiple sets of adjusting frames 319 to form different tilt angles, and the adjusting frames 319 drive the rotating sleeve 318 to move along the first annular groove 317 on the surface of the central shaft 313. The fixed-axis rotation, through the external vertical frame 327, drives multiple sets of depth-dispensing components 320 to form different dispensing tilt angles, constructing a three-dimensional dispensing layout with multiple water depths and multiple points. By controlling the number of rotations of the threaded rotating rod 314, the tilt angle can be precisely controlled to adapt to full coverage dispensing in waters of different widths. At the same time, the outer ring 323 rotates synchronously around the guide tube 321 with the internal connecting pipe 3210. The rubber ring 322 on the surface of the guide tube 321 forms a dynamic seal during the rotation of the outer ring 323, ensuring that there is no leakage or pressure drop during the transportation of the mixed liquid.

[0055] Step S4, Quantitative Dispensing Closed-Loop Operation: The electric push rod 331 of the quantitative dispensing component 330 is activated, driving the end connecting pipe 332 to cause the connecting piston 333 to reciprocate linearly along the inner wall of the inner pipe 334, completing the entire cycle of a single quantitative dispensing operation. This cycle is divided into two strokes:

[0056] Step S41, Suction Stroke: The telescopic end of the electric push rod 331 retracts, driving the connecting piston 333 to move closer to the electric push rod 331. A negative pressure is formed in the cavity of the internal tube 334. The rubber cup piston 335 forms a one-way seal to prevent the mixture from flowing back to the electric push rod 331. The mixture in the storage tank 200 enters the tube through the liquid inlet 3320 of the end connecting tube 332. The pressure of the mixture pushes the sealing ball 338 to compress the spring 339, opening the flow channel of the rubber block 337. The mixture is continuously injected into the cavity of the internal tube 334, completing the liquid injection.

[0057] Step S42, Pushing Stroke: The telescopic end of the electric push rod 331 extends, driving the connecting piston 333 to move away from the electric push rod 331. The pressure of the mixed liquid in the cavity of the internal tube 334 acts in the opposite direction on the sealing ball 338. At the same time, the spring 339 rebounds, causing the sealing ball 338 to abut against the rubber block 337 to form an end face seal, completely blocking the backflow of the mixed liquid. The connecting piston 333 pushes a metered amount of mixed liquid in the cavity to be transported through the conduit 321 to the outer ring 323, and then through the internal connecting tube 3210 and the external extension tube 324 in sequence, accurately releasing it to the preset depth and position of the target water body. By adjusting the telescopic stroke of the electric push rod 331, the single release amount can be adjusted. By adjusting the reciprocating frequency, the speed of the release vessel 100 can be matched to control the total release amount per unit water area.

[0058] Step S5, Full-area deployment and equipment cleanup: Release the vessel anchor and drive the deployment vessel 100 to travel at a constant speed along the preset treatment route. During the journey, steps S2-S4 can be repeated. Adjust the deployment depth, tilt angle and single deployment amount dynamically according to changes in water depth and pollution level to complete the uniform deployment of microbial carriers throughout the target water area. After the full-area deployment is completed, turn off the electric push rod 331, reset the external extension pipe 324 and the control deployment component 310 to their initial state, and drive the deployment vessel 100 back to the shore. Use clean water to rinse and maintain the deployment pipeline, internal pipe 334, end connection pipe 332 and other components to prevent microbial residue from clogging the pipeline, thus completing the entire deployment operation.

10. A method for using a microbial carrier delivery device for river and lake water treatment, characterized in that, Includes the following steps: Step S1: Based on the pollution level, water depth and treatment requirements of the target river and lake water area, prepare a microbial carrier mixture of corresponding concentration and inject the mixture into the release storage tank (200) inside the release vessel (100); check the pipeline sealing performance, sliding fit accuracy and transmission connection reliability of the release mechanism (300), reset each component to the initial state, and then drive the release vessel (100) to the preset release point of the target treatment water area; Step S2: Based on the vertical water depth of the target water area and the requirements for pollution stratification treatment, pull the depth vertical plate (326) to slide along the external vertical frame (327), and drive the external extension pipe (324) to slide synchronously along the outer wall of the internal connecting pipe (3210) through the connecting frame (325) to adjust the vertical placement depth of the outlet of the external extension pipe (324); after the depth is adjusted to the target position, insert the positioning pin (328) into the corresponding positioning hole (329) on the depth vertical plate (326), and make the end of the positioning pin (328) pass through the external vertical frame (327) to complete the mechanical locking of the placement depth; Step S3: Rotate the threaded rotating rod (314) of the control and release assembly (310), and drive the threaded sleeve (316) to move axially along the threaded rotating rod (314) through threaded transmission, thereby driving the crankshaft (315) to make horizontal linear displacement; during the horizontal displacement of the crankshaft (315), the second annular groove (3110) arranged axially and having radially differentiated eccentric heights on its surface can simultaneously drive multiple sets of control frames (319) to form different tilt angles, and the control frame (319) drives the rotating sleeve (318). The first annular groove (317) on the surface of the central axis (313) rotates on a fixed axis, thereby driving multiple sets of depth delivery components (320) to form different delivery tilt angles through the external vertical frame (327), thus constructing a three-dimensional delivery layout with multiple water depths and multiple points; at the same time, the outer ring (323) rotates synchronously around the guide tube (321) with the internal connecting pipe (3210), and the rubber ring (322) on the surface of the guide tube (321) forms a dynamic seal during the rotation of the outer ring (323), ensuring that there is no leakage and no pressure drop during the delivery of the mixed liquid; Step S4: Start the electric push rod (331) of the quantitative dispensing component (330), drive the end connecting tube (332) to drive the connecting piston (333) to reciprocate linearly on the inner wall of the inner tube (334), and complete the full cycle of a single quantitative dispensing: Step S41, Suction stroke: The electric push rod (331) drives the connecting piston (333) to move closer to the electric push rod (331), and a negative pressure is formed in the cavity of the internal tube (334). The piston cup (335) forms a one-way seal to block the backflow of the mixture. The mixture in the storage tank (200) enters the tube through the liquid inlet (3320) of the end connecting tube (332), pushes the sealing ball (338) to compress the spring (339) to open the flow channel, and the mixture is continuously injected into the cavity of the internal tube (334) to complete the liquid injection. Step S42, Pushing stroke: The electric push rod (331) drives the connecting piston (333) to move away from the electric push rod (331). The spring (339) rebounds and drives the sealing ball (338) to abut against the rubber plug (337) to form an end face seal. The connecting piston (333) pushes a quantitative amount of mixed liquid in the cavity to be transported to the outer ring (323) through the conduit (321), and then through the internal connecting pipe (3210) and the external extension pipe (324) in sequence, accurately delivering it to the preset depth and position of the target water body. Step S5: Drive the delivery vessel (100) to travel at a constant speed along the preset treatment route. During the journey, steps S2-S4 can be repeated to dynamically adjust the delivery depth, tilt angle and single delivery amount to complete the uniform delivery of microbial carriers throughout the target water area. After the delivery of the entire water area is completed, turn off the electric push rod (331), reset the external extension pipe (324) and the control delivery component (310) to the initial position, and use clean water to rinse and maintain the delivery pipeline and components.
