Description

Technical Field

[0001] The present invention relates to the technical field of marine environmental protection, in particular to a heavy metal treatment device for seaweed protection areas for marine environmental protection. Background Art

[0002] At present, coastal countries and island countries attach great importance to the impact of heavy metals on the marine environment. The so-called heavy metals refer to metals with a density greater than 5g / cm3. Due to the rapid development of industrial and agricultural production, especially the rapid development of light industry and heavy industry in coastal areas, heavy metal pollution in the marine environment has become increasingly serious worldwide. Since most heavy metal elements are input through rivers, which constitute the main way for them to enter the sea, the pollution of heavy metals in estuary waters is relatively serious. Seagrass is a monocotyledonous higher plant that lives in shallow waters in tropical and temperate seas. It is the only angiosperm submerged in shallow sea waters and is widely distributed. In coastal waters, seagrass plays a very important role in the marine ecosystem. It not only absorbs nutrients, improves water quality, and provides habitats, breeding grounds, and food sources for many animals, but also stabilizes the bottom sediment, resists wind and waves, and protects the coast. Seagrass beds also have a huge carbon storage capacity. Heavy metal pollution also has a significant impact on seagrass. Heavy metals reduce photosynthetic efficiency by destroying the ultrastructure of chloroplast membranes and endoplasmic membranes, reducing chloroplast synthesis, blocking electron transfer in electron transporters, and destroying key enzymes in the Calvin cycle and closing stomata, thereby limiting the efficiency of CO2 fixation. Therefore, when protecting seagrass, it is necessary to prevent seagrass from being affected by heavy metals.

[0003] Current heavy metal treatment generally places iron-containing frames in long-term contact with seaweed. The free iron elements in the frames will couple with heavy metal elements, reducing heavy metal pollution. However, in actual application, the height of current seaweed protection frames is generally fixed. The growth height of seaweed varies, and the depth of seawater in different areas also varies, making the current protection frames unable to meet the growth needs of different seaweeds.

[0021] (3) Beneficial effects

[0023] 1. The floating grooves, outer corner guide grooves, and inner corner guide grooves provided inside the fixed outer frame and at its corners provide floating space for the floating inner frame. In combination with the connecting blocks and sliding guide blocks at the corners of the floating inner frame, the position of the floating inner frame is effectively guided and restricted when the floating inner frame floats and rises along the floating grooves, so that the floating inner frame can float more stably inside the fixed outer frame. By connecting the swivel seat and the movable guide wheel, the edges of the floating inner frame are in rolling contact with the movable guide wheel when floating, thereby reducing friction and making the floating inner frame more flexible when rising and falling without any jamming.

[0024] And with the help of the hollow floating blocks at the bottom corners of the floating inner frame and the top floating frame, the floating inner frame can be driven to rise and fall through the buoyancy of the hollow floating blocks and the top floating frame, and the hollow floating blocks and the top floating frame mainly float adaptively according to the depth of the sea water, so that the floating inner frame can adjust its operating height according to the depth of the sea water, so that the floating inner frame can be suitable for sea water of different depths, thereby enabling it to better protect seaweeds of different growing heights.

[0025] 2. The outer protective net set on the edge of the fixed outer frame and the inner protective net set on the edge of the floating inner frame can better protect the aquatic plants inside. The outer protective net, the inner protective net and the separating mesh plate can effectively resist the impact of seawater, so that the aquatic plants can grow better on the inner side of the fixed outer frame and the floating inner frame.

[0027] The cone extrusion head is used to extrude the top of the plurality of L type sliding rods, so that the plurality of L type sliding rods expand outward, the push block compresses the extrusion spring, and the guide rod guides and limits the moving position of the L type sliding rod. Through the outward expansion of the plurality of L type sliding rods, the bottom of the L type sliding rod is pushed out of the push-out slot and extends into the soil, so that after the stable column is inserted into the soil, the support stability of the bottom of the stable column is further reinforced through the expansion of the L type sliding rod, so that it can effectively resist the impact of seawater.

[0028] 4, through the first and second butt joint seats installed on both sides of the stable bottom frame, in combination with the clamping block and clamping groove on the edge of the first butt joint seat, and the support spring sheet, clamping block, inclined slot, clamping groove, pulling groove, pull block and movable slot inside the second butt joint seat, the clamping block can be clamped into the clamping groove when the first and second butt joint seats are connected;

[0029] The clamping block extrudes the clamping block, the inclined slot at the top of the clamping block makes the clamping block retract into the movable slot under the extrusion, and the support spring sheet is compressed.

The top edge of the L-shaped sliding rod 23 is provided with a push block 24, and the end of the push block 24 is connected with a guide rod 25 along its vertical direction.

[0044] Two first docking sockets 31 are symmetrically connected to the right side of the stable bottom frame 1, and two second docking sockets 32 are connected to the left side of the stable bottom frame 1 corresponding to the first docking sockets 31. A clamping block 33 is provided at the top of the first docking socket 31, and a clamping slot 34 is provided inside the clamping block 33;

[0045] The second docking card seat 32 is provided with a movable groove 41 inside, and a clamping groove 38 is provided on one side of the inside of the second docking card seat 32 at a position corresponding to the clamping block 33. A support spring piece 35 is embedded in the inner side of the movable groove 41, and a clamping block 36 is connected to the end of the support spring piece 35.

Through the pulling groove 39 and the pulling block 40, it is convenient to pull the card block 36 to move, thereby facilitating the quick release of the connection restriction between the first docking card seat 31 and the second docking card seat 32.

[0046] The working principle and use process of the present invention are as follows: first, the fixed outer frame 2 and the floating inner frame 4 are placed around the periphery of the water plants, and the stable bottom frame 1 is fixed. The mounting seat 17, the inner tube 18, the stable column 19, the limit plate 20 and the pointed rod 21 symmetrically installed on the edge of the stable bottom frame 1 are used to anchor the bottom of the stable bottom frame 1 so that it can be more stably inserted into the sea, thereby ensuring that the stable bottom frame 1 remains stable during use;

[0047] After the stabilizing column 19 is inserted into the mud in the sea through the pointed rod 21, the rotating disk 30 is rotated, and the driving screw 29 and the conical extrusion head 28 are driven to rotate by the rotating disk 30, so that the driving screw 29 drives the conical extrusion head 28 to move downward, thereby utilizing the conical extrusion head 28 to squeeze the tops of the multiple groups of L-shaped sliding rods 23, thereby causing the multiple groups of L-shaped sliding rods 23 to expand outward, and the push blocks 24 compress the extrusion springs 26, while the guide rods 25 guide and limit the moving positions of the L-shaped sliding rods 23. Through the outward expansion of the multiple groups of L-shaped sliding rods 23, the bottoms of the L-shaped sliding rods 23 pass through the ejection grooves 27 and extend into the mud. Therefore, after the bottom of the stabilizing column 19 is inserted into the mud, the support stability of the bottom of the stabilizing column 19 is further reinforced by the expansion of the L-shaped sliding rods 23, so that it can effectively resist the impact of seawater.

[0048] Next, by the outer protective net 3 provided on the edge of the fixed outer frame 2 and the inner protective net 5 provided on the edge of the floating inner frame 4, the aquatic plants inside are better protected. The outer protective net 3, the inner protective net 5 and the separating mesh plate 7 can effectively resist the impact of seawater, so that the aquatic plants can grow better on the inner side of the fixed outer frame 2 and the floating inner frame 4. The separating mesh plate 7 is snap-fitted into the limiting card slot 6 by snapping. The limiting card slot 6 is provided with multiple groups, so that the position of the separating mesh plate 7 can be adjusted conveniently, thereby meeting the flexibility of the growth of the aquatic plants and further enabling the aquatic plants to grow more freely.

[0049] When the seawater depth in the aquatic plant growth area is constantly changing, the floating grooves 9, the outer corner guide grooves 8 and the inner corner guide grooves 10 provided inside the fixed outer frame 2 and at its corners are conveniently provided with floating space for the floating inner frame 4. In combination with the connecting blocks 14 and the sliding guide blocks 15 at the corners of the floating inner frame 4, the position of the floating inner frame 4 is effectively guided and restricted when the floating inner frame 4 is floating and lifted along the floating grooves 9, so that the floating inner frame 4 can float more stably on the inner side of the fixed outer frame 2. When the floating inner frame 4 floats, the connecting swivel seat 11 and the movable guide wheel 12 are used to make the edge of the floating inner frame 4 roll in contact with the movable guide wheel 12 when floating, thereby reducing friction, making the floating inner frame 4 more flexible during lifting and lowering without jamming.

[0050] With the help of the hollow floating blocks 13 at the bottom corners of the floating inner frame 4 and the top floating frame 16, the floating inner frame 4 can be driven to rise and fall by the buoyancy of the hollow floating blocks 13 and the top floating frame 16. The hollow floating blocks 13 and the top floating frame 16 mainly float adaptively according to the depth of the seawater, so that the floating inner frame 4 can adjust its operating height according to the depth of the seawater, making it suitable for seawater of different depths, thereby enabling it to better protect seaweeds of different growing heights;

[0051] When two or more fixed outer frames 2 need to be combined for use, the stable bottom frames 1 need to be hooked and limited. By using the first docking card seat 31 and the second docking card seat 32 installed on both sides of the stable bottom frame 1, combined with the clamping block 33 and the clamping groove 34 on the edge of the first docking card seat 31, and the supporting spring piece 35, the clamping block 36, the oblique groove 37, the clamping groove 38, the pulling groove 39, the pulling block 40 and the movable groove 41 inside the second docking card seat 32, the clamping block 33 can be clamped into the clamping groove 38 when the first docking card seat 31 and the second docking card seat 32 are connected.

[0052] The clamping block 33 is used to squeeze the clamping block 36, and the inclined groove 37 at the top of the clamping block 36 is used to make the clamping block 36 retreat into the movable groove 41 under the extrusion action, and compress the support spring piece 35. After the end of the clamping block 36 is clamped into the position corresponding to the clamping groove 34, the reset support function of the support spring piece 35 is used to make the clamping block 36 clamp into the clamping groove 34, thereby realizing the clamping limit between the first docking clamping seat 31 and the second docking clamping seat 32, making it more convenient for the two stable bottom frames 1 to be used in combination. By pulling the groove 39 and the pulling block 40, it is convenient to pull the clamping block 36 to move, thereby facilitating the quick removal of the restriction and making the disassembly process more convenient.
