Description

Technical Field

[0001] The utility model relates to the technical field of ecological treatment, in particular to a lake ecological treatment system. Background Art

[0002] Lake ecological restoration is a comprehensive process aimed at restoring the health and function of lake ecosystems. Lake ecosystems are complex systems that include multiple components such as water bodies, sediments, and biological communities, which are interdependent and interact with each other. However, due to human activities and changes in the natural environment, lake ecosystems are often damaged, resulting in water quality deterioration and biological population decline. The goal of lake ecological restoration is to improve lake water quality, restore the diversity of lake biological communities, and improve the stability and sustainability of lake ecosystems through a series of technical means and management measures.

[0003] A water purification and ecological restoration device is disclosed in a Chinese utility model patent with publication number CN208898600U. The device includes a three-dimensional three-layer structure, which includes, from top to bottom, an emergent plant layer, a submerged plant layer, and an aeration layer. The emergent plant layer and the submerged plant layer are connected by four connecting rods; the emergent plant layer and the aeration layer are connected by a central rotating axis; the three-layer three-dimensional spatial staggered structure allows the submerged plant layer to have a larger sunlight collection area; the four connecting axes can be controlled by solenoid valves to retract and vibrate inward, and submerged plants can be directionally added by remote control and solenoid valve control when the water quality is suitable; the device has a compact structure, complex functions, and can be modularly combined, and is suitable for water bodies of different sizes.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the following defects exist: submerged plants absorb nutrients in the water body during their growth, including nitrogen, phosphorus, etc. For eutrophic lakes, however, submerged plants have a certain growth cycle, and when the submerged plants stop growing, they no longer have the function of regulating water quality. On the contrary, when the submerged plants lose their function, if they remain at the bottom of the lake, it will affect the water quality of the lake itself, thus forming a vicious circle. The annual planned harvesting of submerged plants can be used to transfer excess nutrients in the water body, which plays a positive role in alleviating the eutrophication of the water body. The three-layer structure in the above-mentioned device is fixedly connected, which makes it inconvenient to raise the submerged plants planted at the bottom of the lake to the water surface for replacement. Therefore, it is necessary to improve this scheme. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a lake ecological treatment system.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a lake ecological treatment system, including a floating body, a submerged plant planting assembly is arranged at the bottom of the floating body, the submerged plant planting assembly includes an annular planting box, a plurality of planting pots are arranged in the annular planting box, and a lifting mechanism for driving the annular planting box to move up and down is arranged on the floating body, the lifting mechanism includes a lifting assembly and a driving assembly, the lifting assembly includes a threaded rod passing through the floating body and rotatably connected to the floating body, a guide rod fixed to the bottom of the floating body, a connecting block jointly arranged on the threaded rod and the guide rod, and a connecting plate fixed to the side wall of the connecting block, the threaded rod passes through the connecting block and is threadedly connected to the connecting block, the guide rod passes through the connecting block and slidably cooperates with the connecting block, the connecting plate is fixed to the annular planting box on the side away from the connecting block, and the driving assembly is used to drive the threaded rod to rotate.

[0007] By adopting the above technical solution, when the growth cycle of the submerged plants has ended, the staff drives the threaded rod to rotate by starting the driving assembly. Since the threaded rod is threadedly connected to the connecting block, the guide rod and the connecting block are slidably matched to limit the circumferential movement of the connecting block, so that the connecting block is lifted and lowered in the vertical direction. The connecting block drives the connecting plate and the annular planting box to a position close to the surface of the lake, which is convenient for the staff to move the submerged plants out of the planting pots and plant new submerged plant seedlings in the planting pots again. The submerged plants absorb phosphorus and nitrogen in the lake as nutrients during the growth process, thereby achieving the effect of purifying the lake water quality.

[0008] Furthermore, the driving assembly includes a battery arranged on the top of the floating body, a mounting plate detachably connected to the top of the floating body, a driving motor fixedly connected to the top of the mounting plate, a driving gear fixedly connected to the output end of the driving motor, a rotating shaft rotatably connected to the top of the mounting plate, and a driven gear fixed to the upper end of the rotating shaft and meshing with the driving gear, the driving motor is electrically connected to the battery, a block is fixedly connected to the upper end of the threaded rod, a slot is provided at the lower end of the rotating shaft for engaging with the slot, and a through hole is penetrated at a position corresponding to the slot of the mounting plate.

[0009] By adopting the above technical solution, when the submerged plants at the bottom of the lake need to be replaced, the staff can take a small boat to approach the floating body, and then install the mounting plate to the top of the floating plate. The driving motor is powered by the battery. After the driving motor works, it drives the driving gear to rotate, and the driving gear drives the driven gear and the rotating shaft fixed to the driven gear to rotate. Since the groove at the bottom of the rotating shaft is engaged with the block at the upper end of the threaded rod, the threaded rod is rotated, thereby driving the annular planting box to rise vertically from the bottom of the lake to the upper surface of the lake water body, so that the staff can replace the submerged plants.

[0010] Furthermore, the annular planting box is arranged in a circular ring shape around the threaded rod, the top of the annular planting box is open, an annular groove body that cooperates with the annular planting box is arranged inside the annular planting box, and the multiple planting pots are arranged in the annular groove body.

[0011] By adopting the above technical solution, when the submerged plant planting assembly rises to the surface of the lake, the staff can manually move the annular trough body to make the annular trough body rotate around the axis of the threaded rod in the annular planting box, so that the staff can replace the submerged plants in the annular planting box away from themselves without moving their own position.

[0012] Furthermore, the inner side and the outer side of the annular groove body are provided with slide grooves, and plastic buckles are symmetrically arranged on both sides of each planting pot, and the plastic buckles are engaged with the slide grooves.

[0013] By adopting the above technical solution, the plastic buckle and the slide groove are clipped together to ensure the connection stability between the planting pot and the annular groove body, reduce the probability of submerged plants changing position due to the impact of water flow in the lake, and help submerged plants purify the surrounding water quality.

[0014] Furthermore, an oxygen pump electrically connected to the battery is provided on the top of the floating body, and an oxygen supply pipe of the oxygen pump extends into the lake water.

[0015] By adopting the above technical solution, the oxygen pump can effectively transport oxygen into the water body, thereby increasing the dissolved oxygen content of submerged plants in the water, which is beneficial to improving the survival rate of submerged plants.

[0016] Furthermore, a controller connected to the drive motor for communication is fixed on the top of the float, a protective cover is provided on the top of the float, the battery, drive assembly, oxygen pump and controller are all arranged in the protective cover, and a protective cover is hinged on the top of the protective cover.

[0017] By adopting the above technical solution, the protective cover can protect the battery, drive assembly, oxygen pump and controller, reducing the probability of the battery, drive assembly, oxygen pump and controller being damaged by moisture due to splashing water.

[0018] Furthermore, a water-emerging planting box is arranged around the floating body, and the side wall of the floating body is fixed to the inner side of the water-emerging planting box by a fixing block.

[0019] By adopting the above technical solution and planting emergent plants in the emergent planting box, it is beneficial to improve the purifying effect of the emergent plants on the lake.

[0020] Furthermore, a plurality of air bags are arranged at the bottom of the floating body.

[0021] By adopting the above technical solution, the airbag provides buoyancy to the floating body, so that the floating body and the components installed on the floating body can float to the water surface.

[0022] Furthermore, a sleeve is fixed at the lower end of the threaded rod, a movable block is slidably arranged in the sleeve, a vertical rod penetrating the bottom of the sleeve is fixed at the bottom of the movable block, and a counterweight block is fixed at the lower end of the vertical rod.

[0023] By adopting the above technical solution, the sleeve, movable block, and vertical rod form a telescopic connection structure, which is used to connect the counterweight block and the lower end of the threaded rod, so that the equipment can be used in lakes within a certain depth range. The sleeve, movable block, and vertical rod work together to ensure that the counterweight block is stably located at the bottom of the lake, while the float and the components on the float can be located on the water surface, reducing the probability of interference caused by the buoyancy of the float and the resistance of the counterweight block. The counterweight block improves the stability of the entire device to a certain extent, reduces the possibility of the float being displaced by water flow and wind, and ensures the purification effect of emergent plants and submerged plants on the area.

[0024] Furthermore, a solar photovoltaic panel and a photoelectric converter electrically connected to the battery are arranged on the top of the floating body. The photoelectric converter converts light energy absorbed by the solar photovoltaic panel into electrical energy and stores it in the battery.

[0025] By adopting the above technical solution, the photoelectric converter is a device that converts light energy into electrical energy. Its working principle is based on the photoelectric effect and the photovoltaic effect. The photoelectric effect refers to the energy of photons being transferred to the material when photons interact with matter, causing quasi-continuous transitions of electrons to occur, generating free electrons and holes. The photoelectric effect occurs when the energy of photons is greater than or equal to the band gap energy of the material. By setting up solar photovoltaic panels and photoelectric converters, light energy can be converted into electrical energy and the battery can be charged, ensuring the smooth operation of electrical equipment in the system.

[0026] In summary, the utility model has the following beneficial effects:

[0027] 1. In the present application, when the growth cycle of the submerged plants has ended, the staff drives the threaded rod to rotate by starting the driving assembly. Since the threaded rod is threadedly connected to the connecting block, the guide rod and the connecting block are slidably matched to limit the circumferential movement of the connecting block, so that the connecting block is lifted and lowered in the vertical direction. The connecting block drives the connecting plate and the annular planting box to move to a position close to the surface of the lake, so that the staff can remove the submerged plants in the planting pot and plant new submerged plant seedlings in the planting pot again. The submerged plants absorb phosphorus and nitrogen in the lake as nutrients during the growth process, thereby achieving the effect of purifying the water quality of the lake;

[0040] The submerged plant planting assembly 3 is arranged at the bottom of the floating body 1, and the submerged plant planting assembly 3 includes an annular planting box 31 and a planting pot 32. The annular planting box 31 is arranged below the floating body 1, and the planting pot 32 is arranged in the annular planting box 31 for planting submerged plant seedlings. The planting pot 32 is provided with nutrient soil for providing nutrients to the submerged plants. The bottoms of the annular planting box 31 and the planting pot 32 are both provided with water-permeable holes 311 for facilitating the flow of lake water.

[0041] The lifting mechanism 2 is arranged on the floating body 1, and is used to drive the submerged plant planting assembly 3 to move up and down, and the lifting mechanism 2 includes a lifting assembly 21 and a driving assembly 22. The lifting assembly 21 includes a threaded rod 211, a guide rod 212, a connecting block 213 and a connecting plate 214. The threaded rod 211 passes through the floating body 1 and is rotatably connected to the floating body 1, the guide rod 212 is fixed to the bottom of the floating body 1, and the connecting block 213 is jointly arranged on the threaded rod 211 and the guide rod 212. The threaded rod 211 and the guide rod 212 are arranged in parallel, the threaded rod 211 passes through the connecting block 213 and is threadedly connected to the connecting block 213, and the guide rod 212 passes through the connecting block 213 and is slidably matched with the connecting block 213. The connecting plate 214 is fixed to the side wall of the connecting block 213, and the side of the connecting plate 214 away from the connecting block 213 is fixed to the inner side of the annular planting box 31.

[0042] The driving assembly 22 is used to drive the threaded rod 211 to rotate. The driving assembly 22 includes a battery 221, a mounting plate 222, a driving motor 223, a driving gear 224, a rotating shaft 225 and a driven gear 226. The battery 221 is arranged on the top of the floating body 1, and the mounting plate 222 is detachably connected to the top of the floating body 1. The driving motor 223 is fixedly connected to the top of the mounting plate 222, and the battery 221 supplies power to the driving motor 223. The driving gear 224 is fixedly connected to the output end of the driving motor 223, and the rotating shaft 225 is rotatably connected to the top of the mounting plate 222. The driven gear 226 is fixed to the upper end of the rotating shaft 225 and meshes with the driving gear 224. A clamping block 2111 is fixedly connected to the upper end of the threaded rod 211, and a clamping groove 2251 is provided at the lower end of the rotating shaft 225 to be clamped and matched with the clamping block 2111. A through hole 2221 is penetrated and provided at a position corresponding to the clamping groove 2251 on the mounting plate 222.

[0043] In order to facilitate the staff to replace the submerged plants in the annular planting box 31 away from the side without moving their own position, the annular planting box 31 is arranged in a circular ring shape on the side of the threaded rod 211, and the top of the annular planting box 31 is open. An annular groove body 312 that cooperates with the annular planting box 31 is arranged in the annular planting box 31, and multiple planting pots 32 are arranged in the annular groove body 312. When the staff drives the annular planting box 31 to rise to the position of the surface of the lake through the driving component 22, the staff can manually move the annular groove body 312 to make the annular groove body 312 rotate around the axis of the threaded rod 211 in the annular planting box 31, thereby replacing the submerged plants in the annular planting box 31 that no longer have a purification effect, and put new submerged plant seedlings into the planting pots 32 again. The submerged plants will absorb nutrients in the water body during their growth, including nitrogen, phosphorus, etc., which plays a positive role in alleviating eutrophication of the water body.

[0044] In order to ensure that the submerged plants will not be displaced by external forces and the impact of water flow when they descend into the lake, slide grooves 3121 are provided on the inner and outer sides of the annular groove body 312, and plastic buckles 321 are symmetrically arranged on both sides of each planting pot 32. The plastic buckles 321 are snap-fitted with the slide grooves 3121 to ensure that the submerged plants will not be displaced by external forces and the impact of water flow when they descend into the lake, thereby ensuring that the submerged plants purify the water quality in the area where they are located.

[0045] In order to increase the dissolved oxygen content of submerged plants in water, an oxygen pump 11 electrically connected to the battery 221 is arranged on the top of the float 1. The oxygen supply pipe of the oxygen pump 11 extends into the lake water body. The oxygen pump 11 can effectively transport oxygen into the water body, thereby increasing the dissolved oxygen content of submerged plants in water, which is beneficial to improving the survival rate of submerged plants.

[0046] In order to reduce the probability of the battery 221, the drive assembly 22, the oxygen pump 11 and the controller 12 being damaged by moisture due to splashing water, a controller 12 which is communicatively connected to the drive motor 223 is fixed on the top of the float 1, and a protective cover 13 is arranged on the top of the float 1. The battery 221, the drive assembly 22, the oxygen pump 11 and the controller 12 are all arranged in the protective cover 13, and a protective cover 131 is hinged on the top of the protective cover 13.

[0047] In order to further enhance the purification effect of plants on lakes, an emergent planting box 4 is arranged around the float 1. The side wall of the float 1 and the inner side of the emergent planting box 4 are fixed by a fixing block 41. By planting emergent plants in the emergent planting box 4, it is beneficial to enhance the purification effect of the emergent plants on lakes.

[0048] In order to enable the floating body 1 and the components installed on the floating body 1 to float on the water surface, a plurality of air bags 5 are arranged at the bottom of the floating body 1 .

[0049] In order to reduce the probability of interference caused by the buoyancy of the floating body 1 and the resistance of the counterweight, a sleeve 6 is fixed at the lower end of the threaded rod 211, and a movable block 61 is slidably arranged in the sleeve 6. A vertical rod 62 that runs through the bottom of the sleeve 6 is fixed at the bottom of the movable block 61. The sleeve 6, the movable block 61, and the vertical rod 62 form a telescopic connection structure, which is used to connect the counterweight and the lower end of the threaded rod 211, so that the device can be applied to lakes within a certain depth range. The sleeve 6, the movable block 61, and the vertical rod 62 cooperate to ensure that the counterweight is stably located at the bottom of the lake, while the floating body 1 and the components on the floating body 1 can be located on the water surface. In order to improve the stability of the entire device, a counterweight is fixed at the lower end of the vertical rod 62. The counterweight improves the stability of the entire device to a certain extent, reduces the possibility that the floating body 1 will be displaced due to water flow and wind force, and ensures the purification effect of emergent plants and submerged plants on the area.

[0050] The use principle of a lake ecological treatment system in this embodiment is as follows: when it is necessary to replace the submerged plants at the bottom of the lake, the staff can take a small boat to approach the floating body 1, and then install the mounting plate 222 to the top of the floating plate, and power the driving motor 223 through the battery 221. After the driving motor 223 works, it drives the driving gear 224 to rotate, and the driving gear 224 drives the driven gear 226 and the rotating shaft 225 fixed to the driven gear 226 to rotate. Since the card slot 2251 at the bottom of the rotating shaft 225 is engaged with the card block 2111 at the upper end of the threaded rod 211, the threaded rod 211 is engaged with the card slot 2251 at the bottom of the rotating shaft 225. The threaded rod 211 rotates, and since the threaded rod 211 is threadedly connected to the connecting block 213, the guide rod 212 and the connecting block 213 slide together to limit the circumferential movement of the connecting block 213, so that the connecting block 213 is lifted and lowered in the vertical direction. The connecting block 213 drives the connecting plate 214 and the annular planting box 31 to move to a position close to the surface of the lake, which is convenient for the staff to move the submerged plants in the planting pot 32 out and plant new submerged plant seedlings in the planting pot 32 again. The submerged plants absorb phosphorus and nitrogen in the lake as nutrients during the growth process, thereby achieving the effect of purifying the water quality of the lake. Example

[0051] like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that: a solar photovoltaic panel 14 and a photoelectric converter 15 electrically connected to the battery 221 are arranged on the top of the floating body 1. The photoelectric converter 15 converts the light energy absorbed by the solar photovoltaic panel 14 into electrical energy and stores it in the battery 221. The photoelectric converter is a device that converts light energy into electrical energy. Its working principle is based on the photoelectric effect and the photovoltaic effect. The photoelectric effect refers to when photons interact with matter, the energy of photons is transferred to the matter, causing quasi-continuous transition of electrons, generating free electrons and holes. When the energy of photons is greater than or equal to the band gap energy of the material, the photoelectric effect occurs. By setting up the solar photovoltaic panel 14 and the photoelectric converter 15, light energy can be converted into electrical energy and the battery 221 can be charged, ensuring the smooth operation of electrical equipment in the system.
