Description

Technical Field

[0001] This application relates to the field of environmental governance technology, and in particular to a microbial agent dispensing device for river management. Background Technology

[0002] In existing river ecological management technologies, adding compound microbial agents to water bodies has become an important bioremediation method. However, traditional methods of agent application often involve direct dumping or simple mechanical spraying. Once in open waterways, the agents are easily diluted and dispersed by the water flow, making it difficult to establish effective ecological advantages in a localized area. To overcome this deficiency, in-situ activator technology has emerged. This device is typically fixed on the riverbank or in shallow water areas, where a controlled microenvironment (such as aeration and slow-release carbon sources) is used to cultivate and acclimate the microbial strains before releasing a high concentration of active bacterial solution into the river. Although in-situ activators significantly improve the survival rate and colonization efficiency of the agents, they still face significant technical bottlenecks in practical engineering applications: when the river surface is wide, the physical location of the agent—either on the bank or at a single fixed point—makes it difficult to evenly cover the entire river cross-section. In waters far from the distribution point, such as the center of the river or the opposite side, the density of the microbial agent decreases sharply. The functional microorganisms cannot reach the critical concentration threshold required for colonization, making it difficult to form a stable ecological advantage and greatly reducing the overall treatment effect.

[0003] Furthermore, the in-situ activator consumes a significant amount of electrical energy during operation, whether maintaining a suitable microenvironment for bacterial growth (e.g., continuous or intermittent aeration, hydraulic circulation) or performing pressurized spraying of the bacterial solution. Since many treated river sections are located in remote or wild areas lack access to municipal power, the equipment typically relies on solar photovoltaic panels for power. However, in actual outdoor operating environments, the actual power generation efficiency is often significantly reduced due to the obstruction of trees and buildings along the riverbanks, and the long-term exposure of solar panels to dust, bird droppings, and moisture, making it difficult to provide a stable and sufficient power supply. When the equipment's energy consumption exceeds the solar power load, the activator will frequently shut down or operate at reduced frequency, not only failing to maintain the activated state of the bacteria but also interrupting the spraying operation, severely impacting the continuity and effectiveness of the treatment. Therefore, how to minimize the overall operating energy consumption of the in-situ activator while ensuring effective coverage and activation of the bacterial agent, enabling long-term, stable, and efficient automated operation under limited solar power conditions, has become a key technical problem urgently needing to be solved in this field. Summary of the Invention

[0004] This application proposes a microbial agent dispensing device for river management. Through a linkage structure of dual activators, adjustable flow baffles, sliding ropes, and central positioning piles, the activators are driven to move laterally back and forth in the river channel by the differential thrust of water flow, achieving low-energy self-driven operation with uniform dispensing of microbial agents across the entire cross section and cascaded energy recovery.

[0005] To achieve the above objectives, this application adopts the following technical solution: a microbial agent dispensing device for river management, comprising:

[0006] Two activators, each equipped with a spray tube, a culture chamber and an energy supply component;

[0007] Positioning stakes are placed in the middle of the river channel and have positioning rings on their tops;

[0008] Two traction posts are set up on both banks of the river;

[0009] A sliding rope is connected to two activators at each end, and passes through a positioning ring in the middle and is slidably connected to the positioning ring.

[0010] The traction component has its two ends connected to the traction pile and the activator on the same side, respectively;

[0011] An adjustable baffle plate is provided on the activator to dynamically adjust the water-facing area of ​​the activator;

[0012] During the administration of the microbial agent, the adjustable flow-blocking plates on both sides adjust the water-facing area when the activator moves to its extreme position, thus minimizing the water-facing area of ​​the activator near the bank. The activators on both sides generate differential thrust under the action of the water flow, and through the linkage between the sliding rope and the traction component, drive the two activators to move laterally back and forth along the river channel, achieving uniform administration of the microbial agent across the entire cross-section of the river.

[0013] Furthermore, the positioning stake and positioning ring are located at the bottom of the river, with the height of the positioning ring not exceeding 0.5 meters, so that it is far enough from the water surface that the floating boat and the inflatable boat can pass between the two activators. The positioning stake includes a base plate, a counterweight is fixedly installed on the top of the base plate, and an anti-slip cone is provided on the bottom of the base plate. The counterweight is provided with a connecting groove, and a hammer rod is detachably connected to the connecting groove for easy disassembly and installation.

[0014] Furthermore, the upper part of the positioning ring is "n"-shaped. This allows it to withstand upward oblique forces effectively without affecting the sliding of the sliding rope.

[0015] Furthermore, the traction component is a rotating arm, and the traction pile is hinged to the traction component. The traction component is equipped with an electrically driven locking cylinder, which has a telescopic head. The traction pile is equipped with a locking hole corresponding to the telescopic head. In windy weather, the traction component can be locked, and the wind force is borne by the traction pile near the shore.

[0016] Furthermore, the traction pile is equipped with an angle sensor, so that the traction component is in the middle position when encountering strong winds. The position of the activator is determined by the angle of the traction component, and the movement status of the activator is monitored.

[0017] Furthermore, a connecting component is provided between the traction component and the activator. This connecting component includes a connecting ring at the end of the traction component, with a floating column movably sleeved around the connecting ring. A float is located at the upper end of the floating column, ensuring the floating column remains near the water surface. A connecting rod is located at the top of the floating column, and this connecting rod is connected to the activator via a connecting rope. The connecting rope is of appropriate length, allowing the activator to pass over the sliding rope without colliding with it when moving towards the positioning stake, and preventing the activator from running aground when moving towards the shore.

[0018] Furthermore, the adjustable flow baffle includes a water-blocking plate and a buoyancy chamber, with the buoyancy chamber connected to an air pump. The position of the water-blocking plate is adjusted by regulating the buoyancy chamber, thereby adjusting the contact area with the water flow.

[0019] Furthermore, the activator includes a main float and an incubator. The incubator has an incubation chamber that is always submerged in water. The incubation chamber is connected to an inlet and a spray pipe. The incubation chamber is connected to an air pump through a pressurization port. The incubation chamber is also equipped with a pressure relief port. The spray pipe, pressure relief port, inlet, and pressurization port are all equipped with solenoid valves.

[0020] Furthermore, the air pump's intake port is connected to the buoyancy chamber via a connecting pipe. When the activator requires increased hydraulic pressure, the buoyancy chamber is connected to the air pump's intake side via the connecting pipe. The air pump transfers the pressure inside the buoyancy chamber to the culture chamber, achieving energy recovery and utilization.

[0021] The beneficial effects of this invention are as follows:

[0022] This application provides a microbial agent dispensing device for river management. It employs a dual-activator system connected by a sliding rope, linked to a central positioning pile and traction piles on both banks. An adjustable baffle dynamically adjusts the water-facing area of ​​the two activators, cleverly converting the natural kinetic energy of the river flow into mechanical energy driving the activators' lateral reciprocating movement. When the water-facing area of ​​one activator increases, the water flow thrust propels it towards the center of the river, while simultaneously pulling the other activator towards the bank via the sliding rope; the reverse is also true. This hydraulically self-driven mode requires no additional power configuration, allowing the two activators to continuously and alternately sweep across the river cross-section, ensuring uniform release of the microbial agent throughout the entire river width and providing a concentration guarantee for the functional microorganisms to establish an ecological advantage across the entire cross-section. More importantly, since the spraying points are dynamically distributed throughout the river as the activator moves, the bacterial solution can be directly discharged into the water body nearby without having to overcome the resistance of long-distance pipeline transportation or high-pressure atomization. This significantly reduces the head requirement and instantaneous power of the spraying pump, thereby reducing the power consumption of the bacterial agent application process from the source and achieving the dual goals of wide coverage and energy saving.

[0031] 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.

[0032] Example 1, please refer to Figures 1-3A microbial agent dispensing device for river management includes two activators 4, each equipped with a spray pipe 406 and corresponding equipment required for cultivating microbial communities, including batteries, solar panels, heaters, pH adjustment devices, etc. The two activators 4 are connected together by a sliding rope 7.

[0033] It also includes a positioning pile 1 set in the middle of the river channel and traction piles 2 set on both banks of the river channel. Two activators 4 are set on both sides of the positioning pile 1. The positioning pile 1 is connected to the sliding rope 7 through the positioning ring 6. The sliding rope 7 passes through the positioning ring 6 and is slidably connected to the positioning ring 6. The sliding rope 7 will not detach from the positioning ring 6. The activator 4 is connected to the traction pile 2 on the same side through the traction component 3.

[0034] The activator 4 is equipped with an adjustable baffle plate 5, which can adjust the water-facing area of ​​the activator 4. The water-facing areas of the two activators 4 are adjusted alternately. When the water-facing area of ​​one side is larger, the force between it and the water flow is greater, which will pull the other activator 4 to move against the water flow and gradually move towards the positioning pile 1 in the middle. At the same time, under the traction of the traction component 3, the activator 4 on that side will move towards the riverbank. Utilizing the action of the water flow, without the need for additional power, on the one hand, the activator 4 covers the entire river cross section, making the bacterial agent more evenly distributed. On the other hand, the bacterial agent distribution position can be directly set on the activator 4, reducing the demand for distribution pressure and reducing the energy consumption of spraying bacterial agent.

[0035] Please see Figure 4 Because the river management cycle is relatively long, in order not to affect the passage of some floating boats, the positioning pile 1 and positioning ring 6 are located on the riverbed. The height of the positioning ring 6 does not exceed 0.5 meters. Floating boats and inflatable boats can pass between the two activators 4. The positioning pile 1 includes a base plate 101. A counterweight block 103 is fixedly installed on the top of the base plate 101. The positioning pile 1 is stable by its own weight. In order to increase the stability of the base plate 101, an anti-slip cone 102 is provided at the bottom of the base plate 101. A connecting groove 104 is provided on the counterweight block 103. Before the positioning pile 1 is sunk to the riverbed, a hammer rod is inserted into the connecting groove 104. After the positioning pile 1 is sunk, the anti-slip cone 102 is inserted into the riverbed by hammering the hammer rod. After insertion, the hammer rod is pulled out. When the equipment is removed, the positioning pile 1 can be taken out relatively easily. Since the positioning pile 1 is deep into the riverbed, it can be discarded if it cannot be taken out. The upper part of the positioning ring 6 is "n" shaped, which can withstand the upward force well and does not affect the sliding of the sliding rope 7.

[0036] Please see Figure 5The positioning pile 1 can withstand the hydraulic pressure of the two activators 4, but in the event of strong winds, the self-weight of the positioning pile 1 may not be sufficient to maintain stability. The traction component 3 is a rotating arm, and the traction pile 2 is hinged to the traction component 3. The traction pile 2 is a fixed pile foundation, and an angle sensor 201 is provided on the traction pile 2. The traction component 3 is provided with an electrically driven locking cylinder 202, which can be powered by a dry cell battery. The locking cylinder 202 has a telescopic head 203, and the traction pile 2 has a locking hole 204 corresponding to the telescopic head 203. In the event of strong winds, the locking cylinder 202 is powered to drive the telescopic head 203 to extend. When the traction component 3 rotates to the middle position, the telescopic head 203... Align 03 with the locking hole 204 and insert it into the locking hole 204 to lock the traction member 3. The middle position does not refer to the middle position of the rotation angle of the traction member 3, but to the position where the middle position of the sliding rope 7 coincides with the positioning ring 6. At this time, if the activators 4 on both sides are subjected to the same force, they will be symmetrical to each other. Since the traction member 3 cannot rotate with the movement of the activator 4, the wind force is borne by the traction member 3, while the positioning pile 1 is almost unaffected. This prevents the position of the positioning pile 1 from moving when the wind force is too strong. The angle sensor 201 is used to monitor the angle of the traction member 3 and determine the position of the activator 4 by the angle of the traction member 3, thereby monitoring the movement status of the activator 4.

[0037] Please see Figures 1-3 , Figure 6 In the event of strong winds, the activator 4 will move with the wind and may collide with the traction component 3. A connecting component 8 is provided between the traction component 3 and the activator 4. The connecting component 8 includes a connecting ring 801 located at the end of the traction component 3. A floating column 802 is movably sleeved on the connecting ring 801. A float 803 is provided at the upper end of the floating column 802. The float 803 keeps the floating column 802 always near the water surface and adjusts adaptively with the river depth. A connecting rod 804 is provided at the top of the floating column 802. The connecting rod 804 is connected to the activator 4 through a connecting rope 805. The length of the connecting rope 805 is appropriate so that when the activator 4 moves toward the positioning stake 1, it can pass over the sliding rope 7 without colliding with the sliding rope 7. When the activator 4 moves toward the shore, the activator 4 will not run aground.

[0038] In Example 2, the adjustable baffle plate requires additional drive in Example 1. To improve energy utilization and recover the energy used to drive the adjustable baffle plate 5, in Example 2, the adjustable baffle plate 5 includes a water-blocking plate 501 and a buoyancy bladder 502. The buoyancy bladder 502 is connected to an air pump 403, which can inflate and deflate the air. The underwater part of the activator 4 is streamlined, with less resistance to the water flow, thus highlighting the adjustment effect of the water-blocking plate 501. When the water force on the activator 4 needs to be reduced, the buoyancy bladder 502 inflates and expands, the waterline of the activator 4 rises, and the water-blocking plate 501 floats to the surface. Conversely, when the water force is increased, the air is deflated, the activator 4 sinks, and the contact area between the water-blocking plate 501 and the water flow increases.

[0039] A buoyancy tank 502 is located at the bottom of the activator 4. The activator 4 includes a main float 401 and an incubator 402. The incubator 402 has an incubation chamber 404, which is always submerged in water. Bacterial colonies are activated and multiply in the incubation chamber 404. An air pump 403 is installed on the main float 401. The incubation chamber 404 is connected to an inlet 408 and a spray pipe 406. When bacterial agent needs to be sprayed, the air pump 403 is started, the pressurization port 409 is opened, increasing the pressure in the incubation chamber 404. The spray pipe 406 is then opened, and the bacterial solution is sprayed out from the spray pipe 406. The incubation chamber 404 also has a pressure relief port 407. After the bacterial solution is sprayed out, the pressure relief port 407 is opened, the inlet 408 is opened, and the spray pipe 406 and the pressurization port 409 are closed. Under water pressure, river water is poured in from the inlet 408, and the pressure relief port 407 releases pressure simultaneously, allowing water to flow through. The target liquid level is monitored by the water level sensor or by the water filling time. When the target liquid level is reached, the pressure relief port 407 and the water inlet 408 are closed, and a new round of bacterial proliferation begins. The air intake of the air pump 403 is connected to the buoyancy bladder 502 through the connecting pipe 405. A three-way valve is provided at the air intake of the air pump 403. The three-way valve has two air inlets. One air inlet is connected to the atmosphere through a one-way valve, and the other is connected to the connecting pipe 405 through a shut-off valve. When the hydraulic pressure of the activator 4 needs to be increased, the buoyancy bladder 502 is connected to the air intake side of the air pump 403 through the connecting pipe 405. The air pump 403 transfers the pressure in the buoyancy bladder 502 to the culture chamber 404 to realize energy recovery and utilization. The injection pipe 406, pressure relief port 407, water inlet 408 and pressurization port 409 are equipped with corresponding solenoid valves.

[0040] In daily operations, the positions of the two activators 4 are adjusted to the middle position for bacterial activation and proliferation. When spraying is required, the locking cylinder 202 is unlocked, and the two activators 4 move under their respective hydraulic differences, one moving towards the middle of the river and the other towards the riverbank. When they are in position (judged by the angle of the traction component 3), the hydraulic force on the two activators 4 is adjusted. The buoyancy bladder 502 corresponding to the activator 4 near the center is connected to the air pump 403 through the connecting pipe 405, and the air pump 403 is started. Pressurizing the culture chamber 404, opening the spray pipe 406, and spraying bacterial solution, the buoyancy bladder 502 contracts, the height of the activator 4 decreases, the water-blocking plate 501 is submerged underwater, and the hydraulic force it receives increases. The air pump 403 corresponding to the activator 4 near the riverbank is turned on to inflate the buoyancy bladder 502, pressurizing the culture chamber 404 and starting to spray bacterial solution. At the same time, the height of the activator 4 rises, the water-blocking plate 501 floats to the surface, and the hydraulic force it receives decreases. The two sets of activators 4 begin to move in opposite directions to achieve uniform spraying of bacterial solution.
