Description

Technical Field

[0001] This invention relates to a silt restoration device, specifically a river silt in-situ ecological restoration device. Background Technology

[0002] Currently, there are two main methods for the remediation of river and lake silt: physical and biological methods. Physical remediation primarily involves dewatering the silt through mechanical drying, geotextile bag drying, or natural drying, followed by further treatment. Bioremediation technology utilizes the metabolic activities of microorganisms and plants to degrade, absorb, and transform harmful substances in river and lake silt, thereby achieving the goal of removing these harmful substances. Microbial remediation technology is simple to operate and can be used for large-scale remediation of river and lake silt.

[0003] A microbial dispensing device for water ecological management is disclosed in application number CN202010299465.7. The microbial inoculum dispensing unit moves the device to the set microbial inoculum dispensing position through a GPS positioning module and a power module. After moving to the position, it controls the solenoid valve to dispense the microbial inoculum.

[0004] However, existing delivery methods typically involve using a spray gun to deliver microbial strains. In water, however, using a spray gun cannot guarantee that the microbial strains will be accurately delivered to the desired area. Furthermore, if the spray gun has a strong force, the microbial strains may be damaged when they come into contact with the sludge, thus affecting the subsequent sludge treatment effect. Summary of the Invention

[0005] One objective of this invention is to provide an in-situ ecological restoration device for river silt. The device uses a telescopic mechanism to move a carrier plate connected to microbial cells to a placement position, and then uses an adjustment mechanism inside the placement chamber to separate the carrier plate from the device. This ensures that the microbial cells are inserted into the desired area, thereby improving efficiency.

[0006] This objective is achieved using the following technical solution:

[0007] This device includes a float, a power unit mounted on the float, and microbial inoculants. The power unit moves the float to the desired position. The float is equipped with a telescopic mechanism, with a dispensing chamber at its lower end. The telescopic mechanism moves the dispensing chamber to the desired location, eliminating the need for a spray gun and preventing the microbial inoculants from deviating from their projection path due to water flow. This ensures the microbial inoculants are safely inserted into the desired area.

[0008] Secondly, after the telescopic mechanism drives the carrier plate into the sludge, it is necessary to separate the device from the carrier plate. If it is pulled out directly, the carrier plate will be easily removed from the sludge, affecting the stability of the connection between the sludge and the microbial strains, and thus affecting the efficiency of the subsequent sludge treatment.

[0009] Based on this, the inventors also designed a dispensing chamber, which contains a first movable rod and two second movable rods. When connected, the lower end of the first movable rod passes through and connects to the carrier plate, which in turn connects to the microbial inoculum. When the telescopic mechanism extends or retracts, it can move the carrier plate together. When the carrier plate moves to the desired position and the microbial inoculum is inserted into the sludge, the adjustment mechanism in the dispensing chamber causes the two second movable rods to move downward and the first movable rod to move upward. When the first movable rod moves upward, under the action of the second movable rods, the carrier plate will not move upward with the first movable rod. Therefore, under the action of the second movable rods, the carrier plate remains inserted into the sludge and will not move with the movement of the first movable rod.

[0010] Compared with existing structures, this device can directly release microbial inoculants into the release area without being affected by water flow during release. Furthermore, when the microbial inoculants are inserted into the sludge, the device can quickly separate from the microbial inoculants without extracting them from the sludge during the separation process, thus avoiding any impact on the subsequent sludge treatment efficiency.

[0011] Furthermore, the adjustment mechanism is used to drive the two second moving rods to move downwards simultaneously, while the first moving rod moves upwards simultaneously. In the original state, the lower end of the first moving rod passes through the carrying plate and connects to it. When separation is required, the second moving rod moves downwards and contacts the upper end of the carrying plate, creating downward pressure on the carrying plate. At the same time, the first moving rod moves upwards, creating upward pressure on the carrying plate. The upward and downward pressures cancel each other out, thus ensuring that the carrying plate does not separate from the silt during the process of separating the first moving rod from the carrying plate, guaranteeing the stability of the connection between the carrying plate and the silt.

[0012] The adjustment mechanism can have various structures. For example, it can be a telescopic rod connected to the first moving rod and two second moving rods respectively. The extension and retraction of the three telescopic rods control the downward movement of the second moving rod and the upward movement of the first moving rod. However, the three telescopic rods need to be controlled separately, which is not only cumbersome but also inconvenient to operate. The inventor provides an adjustment mechanism that can act on the first moving rod and two second moving rods simultaneously, enabling them to move at the same time, ensuring synchronization and improving efficiency. Specifically, the adjustment mechanism includes the telescopic rod and an adjustment platform. The telescopic rod drives the adjustment platform to move within the dispensing cavity. The lower end face of the adjustment platform is sequentially provided with a first slide rail, a second slide rail, a third slide rail, and a fourth slide rail. The first slide rail, the second slide rail, the third slide rail, and the fourth slide rail are connected in sequence. In the initial state, the lower end of the first moving rod passes through the lower end of the dispensing cavity and the loading plate, and is connected to the loading plate. The lower end of the second moving rod is inside the dispensing cavity. The upper ends of the two second moving rods are located on the second and fourth slides respectively, and the upper end of the first moving rod is located on the third slide. When the loading plate is inserted into the silt, the telescopic rod extends and drives the adjusting platform to move in the loading chamber. The upper end of one of the second moving rods moves from the second slide to the first slide, and the upper end of the other second moving rod moves from the fourth slide to the third slide. The first moving rod moves from the third slide to the second slide. During the movement, the second moving rod moves downward and the first moving rod moves upward. During the process of the first moving rod moving upward and separating from the loading plate, the lower end of the second moving rod contacts the upper end of the loading plate, accelerating the separation between the first moving rod and the loading plate.

[0013] Furthermore, each of the two second moving rods is equipped with a first spring, and the first moving rod is equipped with a second spring. The first and second springs ensure that the upper ends of both second moving rods and the first moving rod are in contact with the lower end face of the adjustment platform. When the lower end of the first moving rod is connected to the loading plate, the upper end of the first moving rod remains in contact with the adjustment platform under the action of the spring, ensuring that the second moving rod can act on the loading plate when separated.

[0014] Preferably, a connecting groove is provided on the carrier plate, and a rubber layer is provided on the first moving rod. The outer diameter of the rubber layer is larger than the inner diameter of the connecting groove. The first moving rod passes through the connecting groove and is connected to the carrier plate through the rubber layer. The rubber layer has elasticity. When the lower end of the first moving rod is inserted into the connecting groove, the connecting groove squeezes the rubber layer, and the rubber layer deforms and inserts into the connecting groove, thus realizing the connection between this structure and the carrier plate. Therefore, when it is necessary to separate the carrier plate, it can be separated quickly and directly through the action of the second moving rod, which is convenient for operation.

[0015] Furthermore, the power assembly includes a transmission rod and a propeller. A first gear disk is connected to the lower end of the transmission rod, and a second gear disk is mounted on the propeller. The first gear disk meshes with the second gear disk, driving the propeller to rotate circumferentially. A fan blade is mounted on the upper end of the transmission rod. The rotation of the transmission rod drives the second gear disk and the propeller to rotate, thereby propelling the device forward. The power assembly also includes a connecting rod with a rotating rod. A third gear disk is mounted on one end of the rotating rod. When the device moves to the desired position, the third gear disk meshes with the first gear disk, and the rotation of the transmission rod drives the rotating rod to rotate circumferentially. The other end of the rotating rod is connected to a telescopic mechanism. The circumferential rotation of the rotating rod drives the telescopic mechanism to extend and retract. Therefore, this device can directly utilize the rotation of the transmission rod of the power assembly to achieve the extension and retraction of the telescopic mechanism, thus moving the microbial strain to the desired location.

[0016] The telescopic mechanism includes a first connecting plate and a second connecting plate. The first connecting plate has two meshing first rotating gears, and the second connecting plate has two meshing second rotating gears. One end of a first rotating gear is connected to a first actuating rod, and the other end of the first actuating rod is hinged to one end of a second actuating rod. The other end of the second actuating rod is connected to the second rotating gear, and the other end of a rotating rod is connected to the first rotating gear. When the rotating rod rotates, it drives the first rotating gear to rotate as well. The two meshing first rotating gears rotate together, and the first rotating gear drives the first actuating rod to rotate. Because the first actuating rod is hinged to the second actuating rod, when the first actuating rod rotates under the action of the first rotating gear, it causes the second actuating rod to rotate as well, extending the distance between the first and second actuating rods and thus extending the telescopic mechanism. When the first rotating gears rotate in the opposite direction, they drive the first and second actuating rods to rotate together, shortening the distance between them and thus shortening the telescopic mechanism.

[0017] In addition, depending on the depth of the river channel, it can also include several telescopic mechanisms. The first rotating gear of two adjacent telescopic mechanisms meshes with the second rotating gear, so that it can be used to treat silt at different depths.

[0018] Preferably, the carrier plate is connected to the microbial inoculum shell, and the microbial inoculum is located inside the microbial inoculum shell. Therefore, when the carrier plate moves the microbial inoculum, the microbial inoculum will not flow out, thus affecting the efficiency of use.

[0019] On the other hand, in this invention, the power assembly also includes an air compressor 26 mounted on a transmission rod, a float plate that is an air storage tank with a floating island function, and a fan blade that drives the transmission rod via an electromagnetic clutch. The transmission rod drives the air compressor to compress and store air in the air storage tank, thus realizing wind energy compressed air energy storage. When the device needs to move, the electromagnetic clutch is disengaged, and wind energy drives the propeller to rotate via the transmission rod, thus moving the device. The device also includes a solar panel that transmits electrical energy to the stator of the air compressor via a controller. The stator of the air compressor starts to rotate, and the stator drives the air compressor to compress and store air in the air storage tank, thus realizing solar energy compressed air energy storage. When the device needs to move, the electromagnetic clutch is disengaged, and the motor drives the propeller to rotate via the transmission rod, thus moving the device.

[0020] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0021] This invention discloses an in-situ ecological restoration device for river silt. This device, through a telescopic mechanism, can directly deliver microbial inoculants to the delivery area via a carrier plate, without being affected by water flow during delivery, and can accurately deliver the microbial inoculants into the silt. At the same time, when the microbial inoculants are inserted into the silt, the device and the microbial inoculants can be quickly separated, and the microbial inoculants will not be extracted from the silt during the separation process, thus not affecting the efficiency of subsequent silt treatment.

[0022] Secondly, the wind directly drives the air compressor motor rotor to work, realizing wind and power synergy and improving work efficiency. This device integrates wind and solar energy to achieve wind, solar and electricity synergy, realize air compression energy storage, has high conversion efficiency and low cost. This device adopts compressed air energy storage and aerodynamic power generation to achieve energy self-sufficiency, without the need for chemical energy storage batteries and mains power supply, is energy-saving and environmentally friendly, has a long service life, and is safe and reliable.

[0023] The telescopic mechanism can extend and retract by rotating the transmission rod in the power assembly, which can further save efficiency. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0037] In the description of this invention, it should be understood that the terms "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "high", "low", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0038] Example 1

[0039] like Figure 1 As shown, the device includes a float 1, a power assembly and microbial strains mounted on the float 1. The power assembly includes a transmission rod 2 and a propeller 5. The lower end of the transmission rod 2 is connected to a first gear disk 3, and a second gear disk 4 is mounted on the propeller 5. The first gear disk 3 can mesh with the second gear disk 4 to drive the propeller 5 to rotate circumferentially.

[0040] An air compressor 12 is mounted on the transmission rod 2, and a fan blade 16 is mounted on the upper end of the transmission rod 2. The float plate is an air storage tank with floating island function. The fan blade drives the transmission rod to rotate via an electromagnetic clutch, and the transmission rod drives the air compressor to compress and store air in the air storage tank, realizing wind energy compression and air energy storage. The air compressor 12 is connected to the aeration nozzle 15. When the device needs to be moved, the electromagnetic clutch is disengaged, and the wind energy drives the first gear disk 3 to rotate via the transmission rod. At the same time, the connecting rod of the propeller 5 extends, causing the first gear disk 3 to mesh with the second gear disk 4. When the first gear disk 3 rotates, it drives the propeller 5 to rotate, realizing the movement of the device.

[0041] This device also includes a solar panel 14, which transmits electrical energy to the stator of the air compressor via a controller. The stator of the air compressor begins to rotate, driving the air compressor to compress and store air in an air tank, thus realizing solar-powered compressed air energy storage. When the device needs to be moved, the electromagnetic clutch is engaged, and the air generator 13 drives the propeller 5 to rotate via a transmission rod, thereby moving the device.

[0042] In some embodiments, the float 1 is provided with a connecting rod 6, which is connected to a telescopic mechanism. The lower end of the telescopic mechanism is connected to a carrier plate 25, on which a number of microbial inoculants are provided. The telescopic mechanism extends and retracts to insert the microbial inoculants on the carrier plate into the silt. In some embodiments, the telescopic mechanism is a telescopic rod, which drives the carrier plate to move.

[0043] Example 2

[0044] In some embodiments, such as Figure 2 As shown, a rotating rod 7 is provided on the connecting rod 6. A third gear disk is provided at one end of the rotating rod 7. The third gear disk can mesh with the first gear disk 3 to drive the rotating rod 7 to rotate circumferentially. The other end of the rotating rod 7 is connected to the telescopic mechanism. The circumferential rotation of the rotating rod 7 drives the telescopic mechanism to extend and retract.

[0045] like Figure 3As shown, the telescopic mechanism includes a first connecting plate 8 and a second connecting plate 17. The first connecting plate 8 has two meshing first rotating gears 9, and the second connecting plate 17 has two meshing second rotating gears 18. One end of the first rotating gear 9 is connected to one end of the first actuating rod 10, and the other end of the first actuating rod 10 is hinged to one end of the second actuating rod 11. The other end of the second actuating rod 11 is connected to the second rotating gears 18, and the other end of the rotating rod 7 is connected to one of the first rotating gears 9. In its initial state, the telescopic mechanism is shortened as shown... Figure 3 As shown, when extension is required, the rotating rod extends, causing the third gear disk 3 to mesh with the first gear disk 3. The first gear disk 3 rotates, driving the third gear disk and the first rotating gear 9 to rotate. During the rotation of the first rotating gear, the two meshing first rotating gears rotate together. The first rotating gear drives the first actuating rod to rotate. Because the first actuating rod is hinged to the second actuating rod, the two second rotating gears mesh with each other and rotate together with the second actuating rod. The distance between the first actuating rod and the second actuating rod shortens, as shown. Figure 4 As shown.

[0046] In some embodiments, multiple telescopic mechanisms are included, with the first rotating gear 9 of two adjacent telescopic mechanisms meshing with the second rotating gear 18. In the original state, as... Figure 5 As shown, the device includes two telescopic mechanisms. The second connecting plate 17 of the first telescopic mechanism is connected to the first connecting plate 8 of the second telescopic mechanism, and two first rotating gears 9 and two second rotating gears 18 on the first connecting plate 17 mesh with each other. In the original state, the telescopic mechanism is shortened as shown... Figure 5 As shown, when extension is required, the rotating rod extends, causing the third gear disk 3 to mesh with the first gear disk 3. The first gear disk 3 rotates, driving the third gear disk and the first rotating gear 9 to rotate. During the rotation of the first rotating gear, the two meshing first rotating gears rotate together. The first rotating gear drives the first actuating rod to rotate. Because the first actuating rod is hinged to the second actuating rod, the two second rotating gears mesh with each other and rotate together with the second actuating rod. The meshing of the two second rotating gears with the two first rotating gears drives the first actuating rod of the second telescopic mechanism to rotate, and also drives the second actuating rod of the second telescopic mechanism to rotate. The distance between the first and second actuating rods of the two telescopic mechanisms shortens, as shown. Figure 6 As shown.

[0047] Example 3

[0048] Based on the above embodiments, the lower end of the telescopic mechanism is provided with a dispensing cavity 19, and a first moving rod 23 and two second moving rods 22 are provided in the dispensing cavity 19. The lower end of the first moving rod 23 passes through the carrier plate 25, and the carrier plate 25 is connected to the microbial strain. An adjustment mechanism is provided in the dispensing cavity 19. The adjustment mechanism includes the telescopic rod 20 and the adjustment platform 21. The telescopic rod 20 is used to drive the adjustment platform 21 to move in the dispensing cavity 19. A first slide rail 211, a second slide rail 212, a third slide rail 213 and a fourth slide rail 214 are sequentially provided on the lower end surface of the adjustment platform 21.

[0049] In the original state, such as Figure 7 As shown, the lower end of the first moving rod 23 passes through the loading plate 25, the lower ends of the two second moving rods are located in the delivery cavity, the upper ends of the two second moving rods 22 are located on the second slide rail 212 and the fourth slide rail 214 respectively, and the upper end of the first moving rod 23 is located on the third slide rail 213.

[0050] When it is necessary to separate the loading platform, the telescopic rod 20 extends, such as... Figure 8 As shown, the upper end of one of the second moving rods 22 moves from the second slide rail 212 to the first slide rail 211, and the upper end of the other second moving rod 22 moves from the fourth slide rail 214 to the third slide rail 213. The first moving rod moves from the third slide rail 213 to the second slide rail 212. During the movement, the second moving rod moves downward and contacts the upper surface of the carrying plate. The first moving rod moves upward. During the process of the first moving rod moving upward and separating from the carrying plate, it is ensured that the carrying plate is inserted into the silt.

[0051] In some embodiments, each of the two second moving rods 22 is provided with a first spring, and the first moving rod 23 is provided with a second spring. The first spring and the second spring cause the upper ends of the two second moving rods 22 and the first moving rod 23 to contact the lower end face of the adjustment table 21. When the lower end of the first moving rod is connected to the carrying plate, the upper end of the first moving rod remains in contact with the adjustment table under the action of the spring, ensuring that the second moving rod can act on the carrying plate when separated.

[0052] Example 4

[0053] Based on the above embodiment, a connecting groove is provided on the carrier plate 25, and a rubber layer is provided on the first moving rod 23. The outer diameter of the rubber layer is larger than the inner diameter of the connecting groove. The first moving rod 23 passes through the connecting groove and is connected to the carrier plate 25 through the rubber layer. The rubber layer has elasticity. When the lower end of the first moving rod is inserted into the connecting groove, the connecting groove squeezes the rubber layer, and the rubber layer deforms and inserts into the connecting groove, thereby realizing the connection between this structure and the carrier plate. When it is necessary to separate the carrier plate, it can be separated quickly and directly through the action of the second moving rod.

[0054] In the above embodiments, such as Figure 9 As shown, the carrier plate 25 is connected to the microbial inoculum shell, which is located inside the shell. The shell includes a shell layer, a mesh framework, and microbial inoculum within the framework. Both the mesh framework and the microbial inoculum are existing structures. A connecting groove 24 is provided at one end of the shell layer, communicating with the interior of the shell layer. A protective membrane is provided on the connecting groove 24. During release, the protective membrane protects the microbial inoculum within the shell layer, preventing it from flowing out. When the connector is inserted into the sludge, the force of the sludge punctures the protective membrane. Therefore, when the connector is inserted into the sludge for fixation, the microbial inoculum within the mesh framework can also be directly released into the sludge.

[0055] The terms "first" and "second" used in this document are merely for clarity of description and are not intended to restrict any order or emphasize importance. Furthermore, the term "connection" used in this document, unless otherwise specified, can refer to a direct connection or an indirect connection via other components.

[0056] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
