Description

Technical Field

[0001] This application relates to the field of ecological environment restoration technology, and in particular to a wetland ecological restoration and environmental management device. Background Technology

[0002] Wetlands are shallow water areas with still or flowing water, such as marshes, which are naturally formed or artificially created. Wetlands play a role in regulating climate, protecting biodiversity, purifying water quality, regulating runoff, providing resources, and providing places for tourism and leisure.

[0003] As industrial wastewater, agricultural non-point source pollution, and domestic sewage are discharged into wetland water bodies, the wetland water bodies become polluted. When the pollution of the wetland water bodies exceeds the wetland's own restoration capacity, the wetland water bodies will be severely polluted, turning into black and odorous water bodies, thereby affecting the function of the wetland.

[0004] Studies show that water hypoxia is a significant cause of black and odorous water in wetlands; increasing oxygen levels in wetland water is a crucial technical step in wetland bioremediation. Increased oxygen levels in the water help the aquatic microbial community transition from anaerobic to aerobic. The establishment of an aerobic microbial community stimulates algal growth and forms a natural reoxygenation mechanism in the wetland, thereby eliminating black and odorous water.

[0005] In existing technologies, aeration devices can be used to oxygenate water bodies. The main types of aeration devices include blower aeration (e.g., delivering gas into the water body) and mechanical aeration (e.g., using impellers to beat the water body).

[0006] When an aeration device is working in the working area of ​​a water body, it can increase the water content in the working area in a short period of time. However, when the aeration device leaves the working area, the water in the working area is difficult to replenish with oxygen, causing the oxygen content in the wetland water to gradually decrease, making it difficult to continuously meet the oxygen requirements of beneficial microorganisms in the water. Summary of the Invention

[0007] In order to continuously meet the oxygen demand of aerobic microorganisms in wetland water bodies and improve the efficiency and effectiveness of wetland water body ecological restoration, this application provides a wetland ecological restoration and environmental management device.

[0008] This application provides a wetland ecological restoration and environmental management device, which adopts the following technical solution:

[0009] A wetland ecological restoration and environmental management device includes a floating mechanism, an aeration mechanism, a material throwing mechanism, and a control mechanism. The floating mechanism includes a floating body and a mounting frame, the mounting frame being fixed to the floating body and used for mounting the aeration mechanism and the material throwing mechanism. The floating body carries the aeration mechanism and the material throwing mechanism, which float on the water surface. The aeration mechanism is used to introduce oxygen into the water, and the material throwing mechanism is used to release oxygen-releasing elements into the water. The oxygen-releasing elements fall into the silt layer at the bottom of the water body, and dissolve and release oxygen in the water to increase the oxygen content in the water. The control mechanism is used to control the operation of the aeration mechanism and the material throwing mechanism.

[0010] By adopting the above technical solution, after the treatment device floats on the wetland water, the aeration mechanism delivers air into the water to quickly increase the oxygen content. Meanwhile, the treatment device's material-throwing mechanism releases oxygen-releasing components into the water. These components fall into the silt layer at the bottom of the water, and are partially or completely buried in the silt layer, minimizing contact between the components and the water. Once in contact with the water, the oxygen-releasing components slowly and continuously release oxygen to continuously increase the oxygen content of the wetland water.

[0011] The aeration system rapidly increases the oxygen content of the water by introducing air into it; simultaneously, the material-dispensing system dispenses oxygen-releasing elements into the water, allowing them to slowly and continuously release oxygen. Through the coordinated operation of these two systems, the wetland water can maintain a high oxygen content for an extended period, restoring and enhancing the activity of aerobic microorganisms. This purifies pollutants, improves water quality, eliminates black and odorous conditions, and ultimately achieves the goals of wetland ecological restoration and environmental management.

[0012] Optionally, the throwing mechanism includes a feeding structure and a guiding structure; the feeding structure includes a hopper, a feeding channel, an intercepting plate, and a linear reciprocating drive; the hopper is fixed on the mounting frame and is used to temporarily store the oxygen-releasing element; the feeding channel is used to transport the oxygen-releasing element in the hopper to the guiding structure; the intercepting plate is disposed at the driving end of the linear reciprocating drive and is disposed within the feeding channel; the intercepting plate is used to control the on / off state of the oxygen-releasing element in the feeding channel; the guiding structure includes a fixed cylinder, a sliding cylinder, and a winch; the fixed... The fixed cylinder is vertically fixed on the mounting frame, the sliding cylinder is disposed inside the fixed cylinder, the winch is fixed on the mounting frame, the traction rope of the winch is fixedly connected to the sliding cylinder, the winch is used to drive the sliding cylinder to slide vertically, and the oxygen-releasing element slides into the sliding cylinder through the feeding channel; when the winch unwinds, the sliding cylinder falls freely, and the insertion end at the bottom of the sliding cylinder is inserted into the silt layer at the bottom of the water body, the oxygen-releasing element impacts the silt layer through the feeding channel and the sliding cylinder, and the oxygen-releasing element is buried in the silt layer.

[0013] By adopting the above technical solution, the accuracy of the oxygen-releasing component's drop position can be improved as it falls along the sliding cylinder, thereby enhancing the uniformity of its distribution within the silt layer. In other words, through the coordinated operation of the guiding structure and the feeding structure, the time for the oxygen-releasing component to release oxygen into the water can be extended, thereby enhancing the activity of aerobic microorganisms in the water, eliminating black and odorous water in wetlands, and further improving the effectiveness of wetland ecological restoration and environmental management.

[0014] Optionally, the guide structure further includes several closed blades, which are movably disposed at the insertion end of the sliding cylinder. The width of the closed blades decreases along the direction away from the sliding cylinder. The contact sides of adjacent closed blades are magnetic, and adjacent closed blades are magnetically attracted to each other to seal the insertion end of the sliding cylinder, thereby preventing water from entering the interior of the sliding cylinder. The oxygen-releasing element falls to force the several closed blades to separate. After passing through the insertion end of the sliding cylinder, the oxygen-releasing element is buried in the silt layer at the bottom of the water body.

[0015] By adopting the above technical solution, the sealing blades seal the insertion end of the sliding cylinder, and the sealing blades form an inclined guide surface at the insertion end of the sliding cylinder, which can increase the insertion depth of the sliding cylinder in the silt layer, thereby increasing the burial depth of the oxygen release component.

[0016] Optionally, along the length of the sliding cylinder, the outer periphery of the sliding cylinder is provided with an abutting protrusion, and the inner periphery of the fixed cylinder is provided with a spiral protrusion. The spiral protrusion is arranged on the vertical sliding path of the abutting protrusion, and the abutting protrusion is used to abut against the spiral protrusion so that the sliding cylinder rotates.

[0017] By adopting the above technical solution, the sliding cylinder is forced to rotate under the action of the abutting protrusion and the spiral protrusion. Thus, when the insertion end of the sliding cylinder is inserted into the silt layer, the insertion depth of the sliding cylinder can be increased, thereby increasing the burial depth of the oxygen-releasing gas.

[0018] Optionally, along the vertically downward direction, the sliding cylinder includes a fixedly connected straight segment and a spiral segment, the straight segment being connected to the spiral segment; the straight segment is slidably connected to the fixed cylinder, and the end of the spiral segment away from the straight segment is the insertion end of the sliding cylinder, the tangent of the insertion end of the spiral segment forming an acute angle with the vertical line.

[0019] By adopting the above technical solution, the sliding cylinder is forced to rotate under the action of the abutting protrusion and the spiral protrusion; while the feeding mechanism releases multiple oxygen-releasing elements at intervals, allowing these elements to be ejected in different directions and at different depths within the silt layer. This enables the oxygen-releasing elements to release oxygen for a longer period, while also ensuring that the water body maintains a high oxygen content for an extended period, thus fully promoting the growth of aerobic microorganisms, improving the water quality of the wetland, and enhancing the effectiveness of wetland ecological restoration.

[0020] Optionally, the rotation direction of the sliding cylinder is consistent with the spiral rotation direction of the oxygen-releasing element.

[0021] By adopting the above technical solution, the rotation direction of the sliding cylinder is consistent with the spiral rotation direction of the oxygen release component, so that the sliding cylinder applies a downward force to the oxygen release component, thereby achieving the purpose of accelerating the oxygen release component.

[0022] Optionally, the guide structure further includes a spoiler, one side of which is fixed to the outer periphery of the sliding cylinder, and a clearance distance is provided between the spoiler and the insertion end of the sliding cylinder; the distance between the spoiler and the sliding cylinder increases in the vertical upward direction.

[0023] By adopting the above technical solution, when the winch pulls the sliding cylinder upward, the inclined baffle will push the water around the sliding cylinder; causing the water flow to carry the silt to the buried ground of the oxygen release element, so as to increase the coverage depth of the silt layer on the oxygen release element and delay the reaction process between the oxygen release element and the water.

[0024] Optionally, the aeration mechanism includes a blower and an aeration pipe. The blower is fixed on the mounting frame, the air inlet end of the aeration pipe is connected to the blower, and the air outlet end of the aeration pipe is inserted into the water. Vertically downwards, the aeration pipe includes a fixed aeration pipe and a telescopic aeration pipe. The fixed aeration pipe has several first air vents, and the telescopic aeration pipe has several second air vents. The first and second air vents are buried in the water. The fixed aeration pipe is fixed on the mounting frame, and the end of the telescopic aeration pipe away from the fixed aeration pipe is connected to the sliding cylinder. When the sliding cylinder slides vertically, it forces the telescopic aeration pipe to compress or extend.

[0025] By adopting the above technical solution, through the sliding cooperation of the aeration pipe and the sliding sleeve, as gas overflows from the first or second vent of the aeration pipe into the water body, the diffusion area of ​​the gas in both the horizontal and vertical directions dynamically changes. This allows the air to fully contact different areas of the water, thereby increasing the overall oxygen content in the water. This ensures that the oxygen content in different areas of the water body is sufficient to meet the growth needs of aerobic microorganisms, improving the water quality of the wetland and enhancing the effectiveness of wetland ecological restoration.

[0026] Optionally, the aeration telescopic pipe is a corrugated pipe, and the second vent is provided on the pipe section of the aeration telescopic pipe.

[0027] By adopting the above technical solution, the second vent is set on the pipe section of the aeration telescopic pipe. When the sliding sleeve pulls the aeration telescopic pipe to deform, the depth of the second vent in the water and the angle between the second vent and the vertical plane will change. Thus, when air is ejected from the second vent, the direction of air jet can be dynamically changed to promote the full reaction between air and different areas of the water and increase the overall oxygen content in the water.

[0028] Optionally, the inner peripheral wall of the fixed cylinder is provided with a plurality of balls, which are spaced apart along the length of the fixed cylinder, and the balls abut against the outer peripheral wall of the sliding cylinder.

[0029] By adopting the above technical solution, ball bearings are installed between the fixed cylinder and the sliding cylinder to reduce the resistance to vertical sliding of the sliding cylinder.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The aeration mechanism rapidly increases the oxygen content in the water by introducing air into it; simultaneously, the material-dispensing mechanism dispenses oxygen-releasing elements into the water, allowing them to slowly and continuously release oxygen. Through the coordinated operation of the aeration and material-dispensing mechanisms, the wetland water can maintain a high oxygen content for an extended period, restoring and enhancing the vitality of aerobic microorganisms in the water. This purifies pollutants, improves wetland water quality, eliminates black and odorous conditions, and ultimately achieves the goals of wetland ecological restoration and environmental management.

[0032] 2. By using a winch to wind or unwind the sliding cylinder, the insertion end of the sliding cylinder is inserted into the silt layer at the bottom of the water body. This improves the accuracy of the oxygen-releasing element's landing position as it falls along the sliding cylinder, thereby increasing the uniformity of its distribution within the silt layer.

[0033] 3. On the one hand, the sealing blades close the insertion end of the sliding cylinder, and the sealing blades form an inclined guide surface at the insertion end of the sliding cylinder, which can increase the insertion depth of the sliding cylinder in the silt layer, thereby increasing the burial depth of the oxygen-releasing element. On the other hand, the sealing blades close the insertion end of the sliding cylinder, and during the process of the sliding cylinder being inserted into the water body, the sealing blades can prevent water from entering the internal channel of the sliding cylinder; thus, when the oxygen-releasing element slides down the internal channel of the sliding cylinder, the resistance encountered by the oxygen-releasing element can be reduced, the velocity of the oxygen-releasing element when colliding with the silt layer can be increased, and the burial depth of the oxygen-releasing element in the silt layer can be increased.

[0048] The following is in conjunction with the appendix Figure 1 Section 13 provides further details regarding this application.

[0049] Example 1

[0050] This application discloses a wetland ecological restoration and environmental management device. In this embodiment, the wetland water body is a polluted, black and odorous water body. The management device floats on the wetland water body and promotes the growth of aerobic microorganisms by oxygenating and reoxygenating the water body, thereby eliminating the black and odorous water body and improving the water quality of the wetland water body.

[0051] Reference Figure 1The wetland ecological restoration and environmental management device includes a floating mechanism 1, an aeration mechanism 2, a material throwing mechanism 3, and a control mechanism 4. The aeration mechanism 2, material throwing mechanism 3, power mechanism 5, and control mechanism 4 are fixed to the floating mechanism 1, which floats on the wetland water. The aeration mechanism 2 is used to introduce oxygen into the water, and the material throwing mechanism 3 is used to release oxygen-releasing components 6 into the water. These components 6 fall into the silt layer 8 at the bottom of the water body, dissolve, and release oxygen to increase the oxygen content. The control mechanism 4 controls the operation of the aeration mechanism 2, material throwing mechanism 3, and power mechanism 5.

[0052] In this embodiment, the oxygen-releasing component 6 is a block made of materials such as calcium peroxide, plant fiber, coconut shell biochar, and diatomaceous earth. Calcium peroxide is a key component of the oxygen-releasing component 6. Calcium peroxide reacts slowly with water to generate oxygen, thereby increasing the oxygen content in the water and maintaining this high oxygen content for a longer period to meet the needs of aerobic microorganisms.

[0053] Reference Figure 1 The floating mechanism 1 includes a floating body 11 and a mounting frame 12. The mounting frame 12 is fixed on the floating body 11 and is used for mounting the aeration mechanism 2, the material throwing mechanism 3 and the power mechanism 5. The floating body 11 carries the aeration mechanism 2, the material throwing mechanism 3 and the power mechanism 5 and floats on the water surface.

[0054] Reference Figure 1 In this embodiment, the float 11 has a closed hollow plastic cylinder structure, allowing it to float on the water in the wetland. Vertically, the float 11 has a first mounting through-hole 111 and a second mounting through-hole 112. The first mounting through-hole 111 is located in the middle region of the float 11, and multiple second mounting through-holes 112 are provided, with several mounting through-holes surrounding the first mounting through-hole 111.

[0055] Reference Figure 1 In other embodiments, the float 11 can also be made of a low-density material such as foam. The mounting frame 12 includes a first base plate 121, a second base plate 122, connecting bolts 123, and a frame 124. The first base plate 121 and the second base plate 122 are fixed to the upper and lower sides of the float 11. The connecting bolts 123 are disposed in the second mounting through hole 112 and are used to connect the first base plate 121 and the second base plate 122. The first base plate 121 is disposed on the side of the second base plate 122 away from the wetland water body. The frame 124 is disposed on the first base plate 121, and the power mechanism 5 is disposed on the second base plate 122, such that the power mechanism 5 is submerged in the wetland water body.

[0056] Reference Figure 1In this embodiment, the power mechanism 5 includes two underwater thrusters 51, which are disposed on both sides of the first mounting through hole 111. The control mechanism 4 is connected to the power mechanism 5, and controls the operation of the two underwater thrusters 51 to achieve forward movement and turning of the treatment device on the water surface. In other embodiments, the power mechanism 5 may also be a jet propulsion device, an electric water jet propulsion device, or other similar mechanisms. This embodiment does not limit the specific structure of the power mechanism 5; the power mechanism 5 is used to drive the treatment device to move on the water surface.

[0057] Reference Figure 1 The frame body 124 is fixed on the first base plate 121, and the material throwing mechanism 3 is disposed on the frame body 124. In this embodiment, the material throwing mechanism 3 includes a feeding structure 31 and a guiding structure 32.

[0058] Reference Figure 1 and Figure 2 The feeding structure 31 includes a hopper 311, a feeding channel 312, an intercepting plate 313, and a linear reciprocating drive 314. The hopper 311 is fixed to the mounting frame 12 and is used to temporarily store the oxygen-releasing component 6. The feeding channel 312 is used to transport the oxygen-releasing component 6 from the hopper 311 to the guide structure 32. The intercepting plate 313 is disposed at the drive end of the linear reciprocating drive 314. The feeding channel 312 has a third mounting through hole 3121 through which the intercepting plate 313 passes. The intercepting plate 313 is disposed within the feeding channel 312 and is used to control the flow of the oxygen-releasing component 6 within the feeding channel 312. In this embodiment, the linear reciprocating drive 314 is a cylinder; in other embodiments, the linear reciprocating drive 314 may also be an electric push rod or other drive structures.

[0059] Reference Figure 1 and Figure 2 The guide structure 32 includes a fixed cylinder 321, a sliding cylinder 322, and a winch 323. The fixed cylinder 321 is vertically fixed above the frame, and the sliding cylinder 322 is disposed inside the fixed cylinder 321; the fixed cylinder 321 and the sliding cylinder 322 are vertically arranged, and the fixed cylinder 321 and the sliding cylinder 322 are disposed through the first mounting through hole 111.

[0060] Reference Figure 2 and Figure 3In this embodiment, a plurality of ball bearings 329 are provided on the inner peripheral wall of the fixed cylinder 321. The ball bearings 329 are spaced apart along the length of the fixed cylinder 321, and abut against the outer peripheral wall of the sliding cylinder 322 to reduce the resistance of the vertical sliding of the sliding cylinder 322. The winch 323 is fixedly mounted on the first base plate 121, and a fixed pulley is provided on the frame 124. The traction rope 3231 of the winch 323 is wound around the fixed pulley and is fixedly connected to the sliding cylinder 322. The winch 323 is used to drive the sliding cylinder 322 to slide vertically. When the winch 323 unwinds, the sliding cylinder 322 falls freely, and the insertion end at the bottom of the sliding cylinder 322 is inserted into the silt layer 8 at the bottom of the water body.

[0061] Reference Figure 1 and Figure 2 The control mechanism 4 is connected to the linear reciprocating drive 314 and the winch 323, and is used to control the operation of the linear reciprocating drive 314 and the winch 323. In this embodiment, the feeding channel 312 is connected to the fixed cylinder 321, so that the oxygen releasing component 6 slides into the sliding cylinder 322 through the feeding channel 312.

[0062] Reference Figure 1 and Figure 4 The oxygen-releasing component 6 impacts the silt layer 8 via the feeding channel 312 and the sliding cylinder 322, and is buried in the silt layer 8.

[0063] The working principle of the throwing mechanism 3 is as follows:

[0064] Reference Figure 1 By winding or unwinding the sliding cylinder 322 using the winch 323, the insertion end of the sliding cylinder 322 is inserted into the silt layer 8 at the bottom of the water body. This improves the accuracy of the oxygen-releasing element 6's drop position as it falls along the sliding cylinder 322, thereby enhancing the uniformity of its distribution within the silt layer 8.

[0065] Reference Figure 1 On the other hand, the sliding cylinder 322 is inserted into the silt layer 8 at the bottom of the water body, so that when the oxygen-releasing element 6 falls into the silt layer 8, the burial depth of the oxygen-releasing element 6 in the silt layer 8 can be increased, thereby reducing the contact between the oxygen-releasing element 6 and the water body, reducing the reaction rate between the oxygen-releasing element 6 and the water body, and prolonging the time for the oxygen-releasing element 6 to release oxygen into the water body.

[0066] Reference Figure 1 That is, through the coordinated cooperation of the guiding structure 32 and the feeding structure 31, the time for the oxygen-releasing component 6 to release oxygen into the water body can be extended, thereby enhancing the vitality of aerobic microorganisms in the water body, eliminating the black and odorous water of the wetland, and further improving the effect of wetland ecological restoration and environmental management.

[0067] Reference Figure 1 and Figure 5 The aeration mechanism 2 includes a blower 21, an aeration pipe 22, and a connecting hose 23. The blower 21 is fixed on the first base plate 121. The air inlet end of the aeration pipe 22 is connected to the blower 21, and the air outlet end of the aeration pipe 22 is inserted into the water. In this embodiment, the blower 21 and the aeration pipe 22 are connected by the connecting hose 23.

[0068] Reference Figure 5 and Figure 6 The aeration pipe 22, running vertically downwards, includes an aeration fixed pipe 221 and an aeration telescopic pipe 222. The aeration fixed pipe 221 has several first vent holes 2211, and the aeration telescopic pipe 222 has several second vent holes 2221. The first vent holes 2211 and the second vent holes 2221 are buried in the water. The aeration fixed pipe 221 is fixed on the mounting frame 12, and the end of the aeration telescopic pipe 222 away from the aeration fixed pipe 221 is connected to the sliding cylinder 322. When the sliding cylinder 322 slides vertically, it forces the aeration telescopic pipe 222 to compress or extend. In this embodiment, the end of the aeration telescopic pipe 222 away from the aeration fixed pipe 221 is fixedly connected to the sliding cylinder 322 via a connecting rod 7 to achieve the purpose of the sliding cylinder 322 driving the aeration telescopic pipe 222 to deform.

[0069] The working principle of the aeration mechanism 2 and the material throwing mechanism 3 working together is as follows:

[0070] Reference Figure 1 and Figure 5 When the sliding sleeve slides vertically, it will pull the aeration telescopic tube 222 to compress or extend. After the aeration telescopic tube 222 is stretched and deformed, it will increase the volume of the internal chamber of the aeration tube 22 and reduce the air pressure in the internal chamber of the aeration tube 22. When the aeration telescopic tube 222 is compressed and deformed, it will reduce the internal space of the aeration tube 22 and increase the air pressure in the internal chamber of the aeration tube 22.

[0071] Reference Figure 5 and Figure 6 On the one hand, in the horizontal direction, as the air pressure inside the aeration pipe 22 increases or decreases, when air escapes from the first vent 2211 and the second vent 2221 into the water, it can change the path of the air in the water, thereby changing the gas diffusion area and expanding the gas diffusion range.

[0072] Reference Figure 5 and Figure 6 On the other hand, in the vertical direction, the vertical length of the aeration pipe 22 in the water body is changed by the compression or stretching deformation of the aeration expansion pipe 222, so as to further improve the diffusion range of gas in the water body.

[0073] Reference Figure 5 and Figure 6 In summary, through the sliding engagement of the aeration pipe 22 and the sliding sleeve, as gas overflows from the first vent 2211 or the second vent 2221 of the aeration pipe 22 into the water body, the diffusion area of ​​the gas in both the horizontal and vertical directions dynamically changes. This allows the air to fully contact different areas of the water, thereby increasing the overall oxygen content in the water. This ensures that the oxygen content in different areas of the water body is sufficient to meet the growth needs of aerobic microorganisms, improving the water quality of the wetland and enhancing the effectiveness of wetland ecological restoration.

[0074] Reference Figure 5 and Figure 6 In this embodiment, the aeration telescopic pipe 222 is a corrugated pipe, and the second vent 2221 is disposed on the pipe section of the aeration telescopic pipe 222. Because the second vent 2221 is disposed on the pipe section of the aeration telescopic pipe 222, when the sliding sleeve pulls the aeration telescopic pipe 222 to deform, the depth of the second vent 2221 in the water and the angle between the second vent 2221 and the vertical plane will change. Therefore, when air is ejected from the second vent 2221, the direction of air jet can be dynamically changed to promote sufficient reaction between air and different areas of the water, thereby increasing the overall oxygen content in the water.

[0075] The implementation principle of a wetland ecological restoration and environmental management device according to an embodiment of this application is as follows:

[0076] Once the treatment device floats on the wetland water, the aeration unit 2 delivers air into the water to rapidly increase its oxygen content. Meanwhile, the material-throwing mechanism 3 of the treatment device releases oxygen-releasing components 6 into the water. These components fall into the silt layer 8 at the bottom of the water, and are partially or completely buried within the silt layer 8, minimizing contact between the components and the water. Upon contact with the water, the oxygen-releasing components 6 slowly and continuously release oxygen to continuously increase the oxygen content of the wetland water.

[0077] Aeration unit 2 rapidly increases the oxygen content in the water by introducing air into it; simultaneously, material throwing unit 3 throws oxygen-releasing components 6 into the water, allowing them to slowly and continuously release oxygen. Through the coordinated operation of aeration unit 2 and material throwing unit 3, the wetland water can maintain a high oxygen content for a longer period, restoring and enhancing the vitality of aerobic microorganisms in the water. This purifies pollutants, improves water quality, eliminates black and odorous conditions, and ultimately achieves the goals of wetland ecological restoration and environmental management.

[0078] Example 2

[0079] The difference between Example 2 and Example 1 is as follows:

[0080] Reference Figures 7 to 9The guide structure 32 also includes several closed blades 325. The closed blades 325 are movably disposed at the insertion end of the sliding cylinder 322. The width of the closed blades 325 decreases along the direction away from the sliding cylinder 322. The contact sides of adjacent closed blades 325 are magnetic. Adjacent closed blades 325 are magnetically attracted and fixed to each other to seal the insertion end of the sliding cylinder 322, so as to prevent water from entering the interior of the sliding cylinder 322. The oxygen release element 6 falls to force the several closed blades 325 to separate. After passing through the insertion end of the sliding cylinder 322, the oxygen release element 6 is buried in the silt layer 8 at the bottom of the water.

[0081] The implementation principle of a wetland ecological restoration and environmental management device according to an embodiment of this application is as follows:

[0082] On the one hand, the sealing blade 325 seals the insertion end of the sliding cylinder 322, and the sealing blade 325 forms an inclined guide surface at the insertion end of the sliding cylinder 322, which can increase the insertion depth of the sliding cylinder 322 in the silt layer 8, thereby increasing the burial depth of the oxygen-releasing element 6. On the other hand, the sealing blade 325 seals the insertion end of the sliding cylinder 322, and during the process of the sliding cylinder 322 being inserted into the water body, the sealing blade 325 can prevent the water body from entering the internal channel of the sliding cylinder 322; thus, when the oxygen-releasing element 6 slides down the internal channel of the sliding cylinder 322, the resistance encountered by the oxygen-releasing element 6 can be reduced, the speed of the oxygen-releasing element 6 when colliding with the silt layer 8 can be increased, and the burial depth of the oxygen-releasing element 6 in the silt layer 8 can be increased.

[0083] Example 3

[0084] The difference between Example 3 and Example 2 is as follows:

[0085] Reference Figure 10 The guide structure 32 also includes a spoiler 326, one side of which is fixed on the outer periphery of the sliding cylinder 322, and a clearance distance is provided between the spoiler 326 and the insertion end of the sliding cylinder 322; the distance between the spoiler 326 and the sliding cylinder 322 increases in the vertical upward direction.

[0086] The implementation principle of a wetland ecological restoration and environmental management device according to an embodiment of this application is as follows:

[0087] During the descent of the sliding cylinder 322, the inclined baffle 326 reduces the resistance experienced by the sliding cylinder 322. When the winch 323 pulls the sliding cylinder 322 upward, the inclined baffle 326 pushes the water around the sliding cylinder 322 away from it. The water then flows towards the insertion end of the sliding cylinder 322, carrying silt with it towards the buried surface of the oxygen-releasing element 6. This increases the coverage depth of the silt layer 8 over the oxygen-releasing element 6, thus slowing down the reaction process between the oxygen-releasing element 6 and the water.

[0088] Example 4

[0089] The difference between Example 4 and Example 2 is as follows:

[0090] Reference Figure 11 and Figure 12 Along the length of the straight segment 3221, the outer periphery of the sliding cylinder 322 is provided with abutting protrusions 327, and the inner periphery of the fixed cylinder 321 is provided with spiral protrusions 328. The spiral protrusions 328 are arranged on the vertical sliding path of the abutting protrusions 327. The abutting protrusions 327 and the spiral protrusions 328 abut against each other, so that the sliding cylinder 322 rotates.

[0091] The implementation principle of a wetland ecological restoration and environmental management device according to an embodiment of this application is as follows:

[0092] Under the action of the abutting protrusion 327 and the spiral protrusion 328, the sliding cylinder 322 is forced to rotate. Thus, when the insertion end of the sliding cylinder 322 is inserted into the silt layer 8, the insertion depth of the sliding cylinder 322 can be increased, thereby increasing the burial depth of the oxygen-releasing body.

[0093] Example 5

[0094] The difference between Example 5 and Example 4 is as follows:

[0095] Reference Figure 13 Along a vertically downward direction, the sliding cylinder 322 includes a fixedly connected straight segment 3221 and a spiral segment 3222, with the straight segment 3221 and the spiral segment 3222 communicating with each other. The straight segment 3221 of the sliding cylinder 322 is slidably connected to the fixed cylinder 321, and an abutment protrusion 327 is disposed on the straight segment 3221 of the sliding cylinder 322. The end of the spiral segment 3222 away from the straight segment 3221 is the insertion end of the sliding cylinder 322, and the tangent of the insertion end of the spiral segment 3222 is set at an acute angle to the vertical line; and a sealing blade 325 is disposed at the end of the spiral segment 3222 away from the straight segment 3221. In this embodiment, the rotation direction of the sliding cylinder 322 is consistent with the spiral rotation direction of the oxygen releasing element 6.

[0096] The implementation principle of a wetland ecological restoration and environmental management device according to an embodiment of this application is as follows:

[0097] Under the action of the abutment protrusion 327 and the spiral protrusion 328, the sliding cylinder 322 is forced to rotate; while the feeding mechanism releases multiple oxygen-releasing elements 6 at intervals, allowing the multiple oxygen-releasing elements 6 to be ejected in different directions, and the burial depth of the multiple oxygen-releasing elements 6 in the silt layer 8 is also different. This allows the oxygen-releasing elements 6 to release oxygen for a longer period of time, while also ensuring that the oxygen content in the water body can be maintained for a longer period of time, so as to fully promote the growth of aerobic microorganisms, improve the water quality of the wetland, and enhance the effect of wetland ecological restoration.

[0098] The direction of rotation of the sliding cylinder 322 is consistent with the direction of rotation of the oxygen-releasing component 6, so that the sliding cylinder 322 applies a downward force to the oxygen-releasing component 6, thereby achieving the purpose of accelerating the oxygen-releasing component 6.

[0099] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
