Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically relating to a river water ecological management device and a river water ecological management method. Background Technology

[0002] Duckweed is a common floating aquatic plant that reproduces and grows extremely quickly. Duckweed affects the aquatic ecosystem of rivers. When the amount of duckweed on the surface of a river reaches a certain level, the dissolved oxygen in the water decreases. A large amount of duckweed blocks sunlight, which is not conducive to the photosynthesis of aquatic organisms. The reduced contact area between oxygen and the water surface causes oxygen deficiency in the water. In severe cases, it can prevent aquatic plants and animals from surviving normally, leading to rapid deterioration of water quality and a great impact on the aquatic environment. Therefore, the proliferation of duckweed is an indirect cause of water pollution.

[0003] Therefore, for ecological restoration, it is necessary to treat duckweed and algae. Currently, the common practice is for workers to use boats and nets to collect them, which is time-consuming, labor-intensive, and inefficient. To address this issue, a search revealed existing technologies that use mechanical bar screens for collection. However, these devices are relatively large and suitable for large bodies of water, but not very suitable for narrower waterways. Another method is to use a water pump for collection, such as the river water environment treatment equipment disclosed in patent CN216972033U. In use, the pump is activated, creating a negative pressure inside the sealed storage chamber, drawing water and floating duckweed and algae into the chamber. The water is then filtered through a bottom filter screen and discharged. After a period of time, the sealed cover can be removed to clean the inside of the storage chamber. This device is compact, suitable for narrow waterways, and uses negative pressure suction for continuous collection, saving time and labor.

[0004] However, the aforementioned device still has the following technical problems:

[0005] Because duckweed may contain large pieces of trash, such as plastic bottles, plastic bags, and foam boards, these items will be absorbed along with the duckweed, leading to two problems: First, it is impossible to collect the duckweed separately; second, large pieces of trash take up a lot of space, and a few large pieces may fill the storage bin, excessively occupying space and affecting the collection and storage of duckweed; third, some large pieces of trash may block the entrance of the storage bin, causing blockages and affecting the entry of duckweed; fourth, this device can only collect duckweed, which is a physical treatment method, and physical treatment alone has limited effect on the ecological restoration of water bodies and cannot achieve good treatment results. Summary of the Invention

[0006] To address the problems existing in the above-mentioned prior art, a river water ecological management device and a river water ecological management method are proposed.

[0007] Firstly, this technical solution proposes a river water ecological management device, comprising an outer casing, an inner filter cylinder housed inside the outer casing, a water pump mounted on the inner bottom of the outer casing, an ear seat fixed to the outer wall of the outer casing, a support mounted on the top of the outer casing, and the bottom end of the support connected to the ear seat; a rotating shaft rotatably connected to the center of the support, the rotating shaft being connected to a drive mechanism for driving the rotating shaft to rotate; and a wheel fixedly connected to the bottom end of the rotating shaft, the wheel being positioned above the outer casing and between the outer casing and the outer casing. A gap is formed, which serves as a flow channel for collecting duckweed, allowing only duckweed to pass through; the side wall of the wheel is provided with at least one set of anti-clogging components, which include a hinge seat, on which a pin is provided, and a rocker arm is connected to the pin, which can rotate around the pin as a fulcrum; a torsion spring is sleeved on the pin; a guide sleeve is fixedly connected to the bottom surface of the bracket, and the outer wall of the guide sleeve has at least one boss; the top end of the rocker arm can slide along the outer wall of the guide sleeve, and when the rocker arm slides onto the boss, the rocker arm can swing around the pin.

[0008] Preferably, at least one set of medicine tanks is also fixedly mounted on the support. The medicine tanks are used to store agents for water remediation. The bottom of the medicine tank has an outlet for discharging the agents. A switch assembly adapted and linked to the rocker arm is provided at the outlet. The switch assembly includes a sealing plug, which is movably disposed inside the medicine tank to block the outlet. A piston rod is fixedly mounted at the bottom of the sealing plug and freely extends through the outlet. A flow channel for the agents to flow is formed between the piston rod and the inner wall of the outlet. A pressure cap is fixedly connected to the bottom end of the piston rod, and a compression spring is sleeved on the piston rod. One end of the compression spring is connected to the pressure cap, and the other end of the compression spring is connected to the bottom of the medicine tank. When the rocker arm swings with the pin as the fulcrum, the top of the rocker arm can support the pressure cap, causing the pressure cap to move upward, and at the same time, the sealing plug moves upward, opening the flow channel.

[0009] Preferably, a lever is also fixedly connected to the wall of the rocker arm, one end of which extends into the flow channel, and the lever can rotate circumferentially along the flow channel.

[0010] Preferably, the bracket has a cross-shaped structure, and the bottom of the bracket has a plug; the ear socket has a socket, and the plug is adapted to be inserted into the socket.

[0011] Preferably, the bottom end of the rocker arm is positioned near the plug.

[0012] Preferably, the driving mechanism includes an impeller, which is fixedly sleeved on the top of the rotating shaft. The water pump is connected to a water outlet pipe, and the outlet of the water outlet pipe is located at the impeller position. The water flow sprayed out through the water outlet pipe drives the impeller to rotate.

[0013] Secondly, this technical solution also proposes a method for river water ecological management, which uses river water ecological management equipment. The specific steps are as follows:

[0014] S1. Installation:

[0015] S11. An inclined interception strip is set up in the river channel, and a collection basket is set between one end of the interception strip and the riverbank for collecting garbage;

[0016] S12. Install several parallel river water ecological management devices along the inclined direction of the interception zone;

[0017] S2. Categorized Collection and Processing:

[0018] S21. Duckweed mixed with plastic bottles and bags floats with the water flow. The water pump and drive device are started. The water pump draws in negative pressure, and the duckweed flows through the flow channel and is collected in the inner filter. Plastic bottles that cannot pass through the flow channel are blocked by the wheel. The wheel drives the rocker arm to rotate under the drive device. The rocker arm drives the lever to rotate, clearing the garbage blocking the flow channel. At the same time, when the rocker arm rotates, it can push the plastic bottles to one side. After being pushed by the levers of multiple river water ecological treatment devices, the plastic bottles are guided to the collection basket for collection.

[0019] S22. During the rotation of the wheel, the top of the rocker arm slides along the outer wall of the guide sleeve. When the top of the rocker arm slides from the outer wall of the guide sleeve to the boss, the rocker arm will swing around the pin. During this swing, the top of the rocker arm moves away from the guide sleeve, and the bottom of the rocker arm moves towards the outer sleeve. During the swing of the top of the rocker arm, the top of the rocker arm will squeeze the pressure cap, causing the pressure cap to move upward. At this time, the pressure spring is compressed, the sealing plug moves upward, the flow channel is opened, and the agent flows into the river. As the rocker arm rotates circumferentially, when the rocker arm slides from the boss to the outer wall of the guide sleeve, the sealing plug returns to its original position and the flow channel is closed.

[0020] S23. If a plastic bag is attached to the rocker arm, as the rocker arm swings around the pivot, the top of the rocker arm moves away from the guide sleeve, while the bottom of the rocker arm moves closer to the outer casing. At this time, the tilt angle of the rocker arm increases, and the rocker arm no longer contacts the floating plastic bag. The plastic bag will then be washed away by the river current, thus achieving self-cleaning of the rocker arm and preventing more and more garbage from sticking to and tangling on the rocker arm.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. This invention features a simple structure and compact size, making it suitable for narrow waterways. The negative pressure created by the pump allows for rapid adsorption and collection of duckweed. Furthermore, the invention includes a wheel and anti-clogging components. The rotating wheel serves three functions: firstly, it acts as a limiting mechanism, with the gap between it and the outer casing serving as a duckweed flow channel, allowing only duckweed to pass through while preventing larger debris such as plastic bottles from passing through, thus achieving a classified collection function; secondly, the wheel acts as a guide, guiding and actuating the plastic bottles towards the collection basket; thirdly, it prevents clogging, as the wheel drives the rocker and lever to rotate, clearing blockages in the flow channel; additionally, the rocker, during its circumferential rotation, also guides and actuates the plastic bottles, further enhancing the guiding effect and facilitating rapid collection.

[0023] 2. This invention also includes a medicine tank, which, in conjunction with physical retrieval, achieves a combined physical and chemical treatment effect. In addition, the switch assembly at the bottom of the medicine tank can be used in conjunction with the anti-clogging assembly. By swinging the rocker arm, the debris wrapped around the rocker arm can be self-cleaned, and the switch assembly can be opened and closed, thereby opening and closing the liquid flow channel. This enables intermittent dosing, which facilitates thorough mixing of the medicine and water, resulting in a slow-release effect.

[0024] 3. This method forms a water treatment system by setting up interception belts, collection baskets, and multiple sets of parallel river water ecological treatment equipment. This system can achieve the classified collection of duckweed and other large pieces of garbage (such as plastic bottles and foam boards), and integrates the advantages of anti-blocking, guidance, classified collection, self-cleaning, intermittent chemical dosing, and physical and chemical treatment.

Detailed Implementation

[0036] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] Example 1

[0038] like Figures 1-8 As shown in the figure, this embodiment proposes a river water ecological management device, including an outer shell 2 with a U-shaped cross-section. An inner filter cylinder 3 is installed inside the outer shell 2. The inner filter cylinder 3 is a basket-type structure with filter holes. A water pump 5 is installed on the bottom of the outer shell 2. The water pump 5 is used to generate negative pressure by suction. In order to facilitate the installation of the inner filter cylinder 3, a partition is fixed on the inner wall of the outer shell 2. The partition is a cross structure or a perforated plate structure.

[0039] A support 6 is also fixed on the outer wall of the outer casing 2. The bottom of the support 6 is connected to a support leg 1. When in use, the support leg 1 of appropriate length is selected according to the actual water conditions.

[0040] The outer wall of the outer casing 2 is fixed with an ear seat 7, and a bracket 6 is provided on the upper part of the outer casing 2. The bottom end of the bracket 6 is connected to the ear seat 7. In this embodiment, in order to facilitate disassembly and assembly, the bracket 6 has a cross-shaped structure and a plug 9 at the bottom of the bracket 6. The ear seat 7 has a socket, and the plug 9 is adapted to the socket for insertion. In use, the plug 9 can be directly inserted into the socket to achieve positioning and installation.

[0041] A rotating shaft 10 is rotatably connected to the center of the bracket 6. The rotating shaft 10 is connected to a drive mechanism for rotating it. A wheel 11 is fixedly connected to the bottom end of the rotating shaft 10. When the rotating shaft 10 rotates, it drives the wheel 11 to rotate. The wheel 11 is positioned above the outer casing 2, forming a gap with it. This gap serves as a flow channel for collecting duckweed, allowing only duckweed to pass through while preventing other debris from passing. At least one set of anti-clogging components is provided on the side wall of the wheel 11; in this embodiment, two sets of anti-clogging components can be provided. The anti-blocking component includes a hinge 12, on which a pin is provided. The pin is connected to a rocker arm 13, which can rotate around the pin as a fulcrum. A torsion spring (not shown in the figure) is sleeved on the pin. A guide sleeve 15 is fixedly connected to the bottom surface of the bracket 6. The outer wall of the guide sleeve 15 has at least one boss 151, which is an arc-shaped structure. The top end of the rocker arm 13 can slide along the outer wall of the guide sleeve 15. When the rocker arm 13 slides onto the boss 151, the rocker arm 13 can swing around the pin. In the initial state, under the elastic force of the torsion spring, the top of the rocker arm 13 is in close contact with the outer wall of the guide sleeve 15. When the rocker arm 13 slides along the outer wall of the guide sleeve 15 to the boss 151, the rocker arm 13 will rotate and swing to a certain extent with the pin as the fulcrum. At this time, the elastic force of the torsion spring increases further. The tilt of the rocker arm 13 increases. The boss 151 mainly plays the role of supporting the top of the rocker arm 13, causing it to move outward.

[0042] In this embodiment, a lever 14 is also fixedly connected to the wall of the rocker arm 13. One end of the lever 14 extends into the flow channel. The lever 14 can rotate circumferentially along the flow channel. The lever 14 plays a role in circumferential unblocking and prevents other garbage from getting stuck and clogging.

[0043] In this embodiment, the driving mechanism can be a motor, or it can be the following structure: it includes an impeller 16, which is fixedly sleeved on the top of the rotating shaft 10. The water pump 5 is connected to a water outlet pipe 22, and the water outlet of the water outlet pipe 22 is located at the position of the impeller 16. The water flow sprayed out by the water outlet pipe 22 drives the impeller 16 to rotate. The advantage of this method is that no additional power source is required, the water pump 5 is fully utilized, and the energy utilization can be maximized, which is energy-saving and environmentally friendly.

[0044] At least one set of medicine tanks 17 are also fixedly installed on the bracket 6. The medicine tanks 17 are used to store agents for water remediation. The bottom of the medicine tanks 17 has an outlet 171 for discharging the agents. A switch assembly adapted and linked to the rocker arm 13 is provided at the outlet 171. The switch assembly includes a sealing plug 191, which is movably disposed inside the medicine tank 17 to block the outlet 171. A piston rod 19 is fixedly installed at the bottom of the sealing plug 191. The piston rod 19 freely passes through the outlet 171. The piston rod 19 and the inner wall of the outlet 171 are... A flow channel for the dispensing of medicine is formed; a pressure cap 20 is fixedly connected to the bottom end of the piston rod 19, and a pressure spring 21 is sleeved on the piston rod 19. One end of the pressure spring 21 is connected to the pressure cap 20, and the other end of the pressure spring 21 is connected to the bottom of the medicine box 17; when the rocker arm 13 swings with the pin as the fulcrum, the top end of the rocker arm 13 also has an upward movement. Using this upward movement, the top end of the rocker arm 13 can support the pressure cap 20, causing the pressure cap 20 to move upward, and at the same time causing the sealing plug 191 to move upward, opening the outlet 171, and thus opening the flow channel.

[0045] It should be noted that in this embodiment, the bottom end of the rocker arm 13 is located near the plug 9. The purpose of this arrangement is that if some plastic bags 27 or similar garbage are wrapped around the bracket 6, the rocker arm 13 can be used to peel them off as much as possible to prevent them from accumulating more and more.

[0046] Example 2

[0047] Continue to refer to the appendix Figure 1-8 This embodiment also proposes a method for river water ecological management, which uses river water ecological management equipment. The specific steps are as follows:

[0048] S1. Installation:

[0049] S11. An inclined interception strip 24 is set up on the river channel. A collection basket 26 is set between one end of the interception strip 24 and the riverbank to collect garbage. The garbage mainly refers to some large pieces of garbage such as plastic bottles 25, foam boards, etc.

[0050] S12. Install several parallel river water ecological management devices along the inclined direction of the interception zone 24;

[0051] S2. Categorized Collection and Processing:

[0052] S21. Duckweed mixed with plastic bottles 25 and plastic bags 27 floats with the water flow. The water pump 5 and the drive device are started. In this embodiment, the drive rod device is an impeller 16. The water pump 5 draws and generates negative pressure. The duckweed flows through the flow channel and is collected in the inner filter cylinder 3. The plastic bottles 25 that cannot pass through the flow channel are blocked by the wheel 11. The wheel 11 drives the rocker arm 13 to rotate under the drive device. The rocker arm 13 drives the lever 14 to rotate, clearing the garbage blocking the flow channel. At the same time, when the rocker arm 13 rotates, it can push the plastic bottles 25 to one side. After being pushed by the levers 14 of multiple river water ecological treatment devices, the plastic bottles 25 are guided to the collection basket 26 for collection. It should be noted that the wheel 11 itself also rotates. It can also play a certain role in pushing and guiding the plastic bottles 25, which is conducive to the collection of the plastic bottles 25.

[0053] S22. During the rotation of the wheel 11, the top of the rocker arm 13 slides along the outer wall of the guide sleeve 15. When the top of the rocker arm 13 slides from the outer wall of the guide sleeve 15 to the boss 151, the rocker arm 13 will swing around the pin. The top of the rocker arm 13 moves away from the guide sleeve 15, and the bottom of the rocker arm 13 moves closer to the outer sleeve 2. During the swinging of the top of the rocker arm 13, the top of the rocker arm 13 will squeeze the pressure cap 20, causing the pressure cap 20 to move upward. At this time, the pressure spring 21 is compressed, the sealing plug 191 moves upward, the liquid flow channel is opened, and the agent flows into the river. As the rocker arm 13 rotates circumferentially, when the rocker arm 13 slides from the boss 151 to the outer wall of the guide sleeve 15, the sealing plug 191 returns to its original position, and the liquid flow channel is closed.

[0054] S23. If a plastic bag 27 is attached to the rocker arm 13, during the swinging of the rocker arm 13 around the pin, the top end of the rocker arm 13 moves away from the guide sleeve 15, while the bottom end of the rocker arm 13 moves closer to the outer casing 2. At this time, the tilt angle of the rocker arm 13 increases. (Refer to the attached document.) Figure 8 The joystick 13 no longer comes into contact with the floating plastic bag 27. At this time, the plastic bag 27 will be washed away by the river current, thus realizing the self-cleaning of the joystick 13 and preventing more and more garbage from sticking to and tangling on the joystick 13.

[0055] Application results:

[0056] Firstly, this invention has a simple structure and small size, making it suitable for narrow waterways. The negative pressure created by the pump 5 allows for rapid adsorption and collection of duckweed. Secondly, the invention also includes a wheel 11 and an anti-clogging component. The rotating wheel 11 serves three functions: firstly, it acts as a limiter, with the gap between it and the outer casing 2 serving as a duckweed flow channel. This channel allows only duckweed to pass through, while larger debris such as plastic bottles 25 cannot pass through, thus achieving a classified collection function; secondly, the wheel 11... The rotating wheel 11 has several functions: First, it guides and moves the plastic bottles 25 towards the collection basket 26, where they are collected. Second, it prevents blockages by rotating the rocker arm 13 and lever 14. Lever 14 can clear blockages in the flow channel, thus preventing blockages. Third, the rocker arm 13 can guide and move the plastic bottles 25 during its circumferential rotation. Combined with the rotation of the wheel 11, the guiding effect is stronger, making it easier to collect the plastic bottles 25 quickly.

[0057] Secondly, the present invention also includes a medicine tank 17, which, in conjunction with physical retrieval, achieves the combined effect of physical and chemical treatment. In addition, the switch assembly at the bottom of the medicine tank 17 can be used in conjunction with the anti-clogging assembly. By swinging the rocker arm 13, the garbage wrapped around the rocker arm 13 can be self-cleaned, and the switch assembly can be opened and closed, thereby opening and closing the liquid flow channel. In this way, intermittent dosing is achieved, which is conducive to the full mixing of the medicine and water, and achieves a slow release effect.

[0058] Thirdly, this method forms a water treatment system by setting up interception belts 24, collection baskets 26, and multiple sets of parallel river water ecological treatment equipment. This system can achieve the classified collection of duckweed and other large pieces of garbage (such as plastic bottles 25 and foam boards), and integrates the advantages of anti-blocking, guidance, classified collection, self-cleaning, intermittent chemical dosing, and physical and chemical treatment.

[0059] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
