Description

Technical Field

[0001] This utility model relates to the field of ecological floating bed technology, specifically to a filter element mechanism and an ecological floating bed. Background Technology

[0002] Ecological floating beds (also known as ecological floating islands or artificial floating beds) are artificial floating platforms where aquatic plants or selected terrestrial plants are fixed to a floating carrier and placed in eutrophic water bodies. The plant roots directly contact the water, absorbing nutrients such as nitrogen and phosphorus, while simultaneously providing an attachment site for microorganisms, forming a "plant-microorganism" symbiotic system. This reduces eutrophication levels, inhibits algae growth, and improves water transparency. Besides purifying water, ecological floating beds also provide habitats for aquatic animals and enhance the aesthetic appeal of the landscape, making them an ecological engineering technology that integrates ecological restoration, landscape beautification, and biodiversity conservation.

[0003] Ecological floating beds are an environmentally friendly water remediation technology evolved from traditional constructed wetlands. This technology removes pollutants from water through plant absorption, microbial transformation, and natural sedimentation. Ecological floating bed technology primarily relies on the adsorption properties of the plants and fillers grown on the floating bed to absorb pollutants from the water. In existing technologies, multiple planting holes are usually set on the ecological floating bed, and the filler is fixed inside the planting holes. The filler is used to fix the roots of the plants. After the filler is saturated, the adsorption effect decreases and the filler needs to be replaced. However, since the ecological floating bed floats on the water surface, disassembly and installation need to be carried out on the water surface, and the operating space is limited, which brings great inconvenience to the replacement of the filler. Utility Model Content The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a filter element mechanism and an ecological floating bed, solving the problem that after the filler in the ecological floating bed has been used for a period of time, the adsorption effect of the filler decreases after the filler becomes saturated, and it is inconvenient to replace the filler.

[0004] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a filter element mechanism, comprising: The first adsorption element has a receiving cavity and one end is open. The other end of the first adsorption element has an planting hole that communicates with the receiving cavity. The side wall of the first adsorption element has a plurality of filter holes that communicate with the receiving cavity, and the receiving cavity is filled with filler. The second adsorption element has an adsorption cavity and is open at one end. The sidewall of the second adsorption element has at least one planting hole and multiple liquid permeation holes communicating with the adsorption cavity, and the adsorption cavity is filled with packing material; and... A sealing element is detachably connected between one end of the first adsorption element and one end of the second adsorption element. The sealing element is used to close or open the opening at one end of the first adsorption element and the second adsorption element.

[0005] In some embodiments, one end of the first adsorption member is provided with a first external thread, and one end of the second adsorption member is provided with a second external thread; The sealing component includes a connecting seat, and both ends of the connecting seat are provided with internal thread grooves that can cooperate with the first external thread and the second external thread.

Multiple perforations communicating with the filter chamber are opened on the top of the floating bed body. The filter element mechanism can be inserted into the filter chamber through the perforations, and the other end of the second accessory abuts against the inner bottom wall of the filter chamber. The other end of the first adsorption member extends to the outside of the floating bed body.

[0008] In some embodiments, the system further includes an underwater propeller, a solar panel, a battery, and a PLC module. At least one underwater propeller is installed at each end of the floating bed body. The solar panel and the battery are both installed on the top of the floating bed body. The solar panel, the battery, and the underwater propeller are electrically connected in sequence, and the PLC module is electrically connected to the battery and the underwater propeller.

[0009] In some embodiments, a plurality of flow guides are provided on opposite sides of the floating bed body and spaced apart along the length of the strip-shaped through hole. When the floating bed body moves, the plurality of flow guides can guide the water flow into the filter chamber.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] To address the technical problem in existing ecological floating beds where the packing material becomes saturated after a period of use, reducing its adsorption efficiency and making replacement inconvenient, this solution provides a filter element mechanism and ecological floating bed. This allows for easy removal and disassembly of the filter element mechanism for replacement of the packing material. The operation is simple, time-saving, and labor-saving, ensuring the reusability of the filter element mechanism.

[0018] Please see Figures 1-4 , Figures 1-4A filter element mechanism according to one embodiment of the present utility model includes a first adsorption element 1, a second adsorption element 2 and a sealing element 3. The first adsorption element 1 has a receiving cavity and one end is open. The other end of the first adsorption element 1 has an planting hole 1a communicating with the receiving cavity. The side wall of the first adsorption element 1 has a plurality of filter holes 1b communicating with the receiving cavity, and the receiving cavity is filled with filler. The second adsorbent 2 has an adsorption cavity and one end is open. The side wall of the second adsorbent 2 has at least one planting hole 2a and multiple liquid permeation holes 2b connected to the adsorption cavity, and the adsorption cavity is filled with filler. The sealing member 3 is detachably connected between one end of the first adsorbent 1 and the second adsorbent 2. The sealing member 3 is used to close or open the opening at one end of the first adsorbent 1 and the second adsorbent 2.

[0019] In practical use, the filter element mechanism is installed on an ecological floating bed. Emergent plants can be planted in planting hole 1a, and submerged plants can be planted in planting hole 2a. Water can enter the containment chamber through multiple filter holes 1b, and the packing material in the containment chamber can adsorb pollutants in the water. Water can also enter the adsorption chamber through multiple liquid permeation holes 2b, and the packing material in the adsorption chamber can adsorb pollutants in the water. When the packing material is saturated, the first adsorption element 1, the second adsorption element 2, and the sealing element 3 can be disassembled, and the packing material in the first adsorption element 1 and the second adsorption element 2 can be replaced so that the first adsorption element 1 and the second adsorption element 2 can be reused for a long time.

[0020] It should be noted that, in one embodiment, one end of the first adsorption member 1 is provided with a first external thread 1c, and one end of the second adsorption member 2 is provided with a second external thread 2c; the sealing member 3 includes a connecting seat, and both ends of the connecting seat are provided with internal thread grooves 3a that can cooperate with the first external thread and the second external thread.

[0021] It is understood that by rotating the first external threaded part with the internal threaded groove 3a at one end of the connecting seat, the first adsorption member 1 can be connected or separated from the connecting seat; after the connecting seat closes the opening at one end of the first adsorption member 1 and the second adsorption member 2, the filler can be confined in the adsorption cavity and the receiving cavity, and the filler can fix the roots and stems of the plants planted in the planting holes 1a and 2a.

[0022] It should be noted that the filler is prepared using river and lake sediment and municipal sludge as the main raw materials, with the addition of a small amount of construction waste, fly ash and corn stalks. After the raw materials are mixed, they are placed in a roller granulator to be formed into round or oval particles with a particle size of 1-3 cm. Then, they are fired at high temperature and cooled to obtain the filler.

[0023] It should be noted that, in one embodiment, the first adsorption element 1, the second adsorption element 2, and the sealing element 3 are all cylindrical; when the first adsorption element 1, the second adsorption element 2, and the sealing element 3 are connected, the axes of the first adsorption element 1, the second adsorption element 2, and the sealing element 3 coincide.

[0024] In addition, it should be noted that planting hole 1a is used for planting emergent plants, such as canna lilies, yellow irises, reeds, and cattails; planting hole 2a is used for planting submerged plants, such as Vallisneria natans and Hydrilla verticillata, which have strong purification capabilities.

[0025] The first adsorption element 1, the second adsorption element 2, and the sealing element 3 are all made of polyethylene material.

[0026] In addition, in one embodiment, a filter chamber is provided inside the floating bed body 4, and strip-shaped through holes 4a communicating with the filter chamber are provided on the opposite side walls of the floating bed body 4. A plurality of perforations 4b communicating with the filter chamber are provided on the top of the floating bed body 4. The filter element mechanism can be inserted into the filter chamber through the perforations 4b, and the other end of the second accessory abuts against the inner bottom wall of the filter chamber. The other end of the first adsorption member 1 extends to the outside of the floating bed body 4.

[0027] It should be noted that, in one embodiment, the inner diameter of the perforation 4b is 15cm, the center interval between two adjacent perforations 4b is 10cm, the outer diameter of the first adsorption member 1 and the second adsorption member 2 is 10cm, and the outer diameter of the sealing member 3 is 11cm.

[0028] In addition, it should be noted that the assembly method of the filter element mechanism and the floating bed body 4 is relatively simple. The filter element mechanism can be removed from the floating bed body 4 during winter or dry season, and then reinstalled for ecological restoration when the time is right. Furthermore, when the filter element mechanism's filler is saturated or the plants die, it can be quickly replaced and repaired without affecting the overall working performance of the floating bed body 4.

[0029] In addition, based on the above scheme, in order to facilitate the movement of the floating bed body 4, it specifically includes an underwater propeller 42, a solar panel 43, a battery 44, and a PLC module 45. At least one underwater propeller 42 is installed at both ends of the floating bed body 4. The solar panel 43 and the battery 44 are both installed on the top of the floating bed body 4. The solar panel 43, the battery 44, and the underwater propeller 42 are electrically connected in sequence, and the PLC module 45 is electrically connected to the battery 44 and the underwater propeller 42.

[0030] Specifically, the floating bed body 4 has two mounting holes at both ends that communicate with the filter chamber. Four underwater propellers 42 are installed on the floating bed body 4 and correspond to each mounting hole. When the underwater propellers 42 drive the floating bed body 4 forward or backward, the movement of the underwater propellers 42 can drive the water flow, making the water in the water area flow. The water can be transported to the filter chamber through the mounting holes. The water is continuously drawn in from the head of the floating bed body 4, purified by the filter media and floating bed plants, and discharged from the mounting hole at the tail. On the one hand, the agitation of the underwater propellers 42 can increase the dissolved oxygen in the water, and on the other hand, the continuous flow of water can reduce the phenomenon of "dead water zone".

[0031] Furthermore, based on the above scheme, multiple flow guides 41 are arranged at intervals on opposite sides of the floating bed body 4 along the length direction of the strip-shaped through-hole 4a. When the floating bed body 4 moves, the multiple flow guides 41 can guide the water flow into the filtration chamber. Specifically, the flow guide 41 includes an L-shaped baffle plate, which forms a water-blocking groove with the side wall of the floating bed body 4. When the underwater propeller 42 drives the floating bed body 4 to move, the L-shaped baffle plate can push the fluid through the strip-shaped through-hole 4a into the filtration chamber, further improving the purification performance of the ecological floating bed.

[0032] It should be noted that, in one embodiment, four solar panels 43 are provided on the top of the floating bed body 4, and the four solar panels 43 are respectively located at the four apex corners of the floating bed body 4; and the solar panels 43 are installed at an angle on the top of the floating bed body 4, specifically, the angle between the plane where the solar panel 43 is located and the top plane of the floating bed body 4 is 45°; the battery 44 and the PLC module 45 are both located below the solar panels 43; this installation method can prevent the battery 44 from being directly exposed to the sun, which would affect the battery's lifespan, and can also make full use of the space of the floating bed body 4. In addition, based on the above scheme, a GPS module 46 is also included. The GPS module 46 is installed on the top of the floating bed body 4 and located below the solar panel 43. The GPS module 46 is electrically connected to the PLC module 45. Specifically, the PLC module 45 controls the start and stop of the underwater propeller 42, thereby controlling the movement trajectory of the floating bed body 4. Specifically, by adjusting the movement of the floating bed body through the PLC module and the GPS module, the floating bed body can be turned and moved to accurately reach the target location. In daily mode, dynamic cruise can be set to perform water body restoration according to the movement trajectory set by the GPS module.

[0033] Furthermore, based on the above scheme, it also includes multiple obstacle avoidance sensors 47, all of which are installed on the side wall of the floating bed body 4, and all of which are electrically connected to the PLC module 45.

[0034] Understandably, when the obstacle avoidance sensor 47 detects that the distance between the floating bed body 4 and the obstacle is too close, the obstacle avoidance sensor 47 can send the distance signal to the PLC module 45, and the PLC module 45 can then control the underwater propeller 42 to adjust the movement direction of the floating bed body 4.

[0035] In addition, based on the above scheme, a water quality testing device 48 is also included, which is installed on the side wall of the floating bed body 4. Specifically, the water quality testing device 48 includes a dissolved oxygen sensor, a COD sensor, an NH3-N sensor, a turbidity sensor, a rate sensor, and a liquid level sensor. The water quality is monitored and transmitted to the data center through each sensor. When the water quality in the area meets the standards, the floating bed body 4 is moved to another area for ecological restoration. When the water quality does not meet the standards and cannot be restored for a long time, the packing material in the filter element mechanism needs to be replaced.

[0036] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
