Description

Technical Field

[0001] The present invention relates to the technical field of water ecological environment restoration, and in particular to a submerged plant collection device and a collection method. Background Art

[0002] Submerged plants play a core role in the restoration of shallow lakes and are the basis for maintaining the diversity of aquatic ecosystems. The growth of submerged plants can effectively improve water quality, reduce nutrient loads, inhibit eutrophication of water bodies, and control the occurrence of algal blooms. Submerged plants absorb nutrients such as nitrogen and phosphorus in the water, improve underwater oxygen-rich conditions, and thus reduce the total nitrogen and total phosphorus content of the water. Studies have shown that in areas covered by submerged plants, oxygen can penetrate into the surface of the sediment, promote the oxidation of iron ions in the sediment, and further reduce the circulation of nutrients. In addition, submerged plants can also improve the transparency of the water body by controlling the growth of algae, thereby restoring and maintaining the ecological balance of the water body.

[0003] In the water ecological restoration project, the planting of submerged plants needs to go through two stages. The first stage is the start-up stage. During this stage, the entire system is in an unstable state, in which the growth of plants, the number and type of microorganisms and the growth of biofilms are all in a gradual development stage. The plant rhizomes continue to grow, the number of microorganisms continues to increase, and the dominant population is gradually formed. At this time, the system's treatment effect on pollutants and operational stability are still changing. The second stage is the stable and mature stage. During this stage, the system is in dynamic balance. The growth of plants only changes periodically with the seasons, and is in a relatively stable state between years. At this time, the treatment effect of the system is fully exerted and the operation is relatively stable. Throughout the process, it is necessary to conduct regular surveys and observations on the growth of submerged plants to adjust the subsequent replanting and maintenance plans. However, the submerged plants that are successfully planted need to be obtained regularly, and there are certain difficulties due to reasons such as water depth and hard bottom mud. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a submerged plant collection device and a collection method, which can obtain submerged plants in deep water areas and retain part of the fetal mud when transplanting seedlings, thereby avoiding plant damage and improving plant survival rate.

[0005] The present invention is achieved through the following technical solutions:

[0006] A submerged plant collecting device comprises a positioning tube and a device body, wherein the device body comprises two mutually adaptable clips, a limit spring connected to the upper parts of the two clips, two movable rods movably connected to the upper ends of the two clips, and a vertical rod movably connected to the two movable rods. Through the interaction between the limit spring and the clip, when the limit spring is in a natural state, the spacing between the upper ends of the two clips is greater than the spacing between the lower ends of the two clips. When the two clips are inserted into the positioning tube, the limit spring is compressed, so that the two clips are relatively tightly embraced.

[0007] According to the above technical solution, preferably, an extension handle is fixedly connected to the outer side of the positioning tube for inserting the positioning tube into the bottom mud of the water body.

[0008] According to the above technical solution, preferably, one or both of the extension handle and the vertical rod are telescopic structures, wherein the telescopic structure includes a plurality of adjustment rods connected by internal thread joints, and the ends of the adjustment rods are threadedly connected to the internal thread joints.

[0009] According to the above technical solution, preferably, large movable rings are respectively provided on both sides of the lower end of the vertical pole, and the vertical pole and the upper end of the movable rod are movably connected through the large movable rings. A small movable ring is provided on the upper side of the clamp, and the clamp and the lower end of the movable rod are movably connected through the small movable ring.

[0010] According to the above technical solution, preferably, the two clips are an inner clip and an outer clip respectively, and the arc length of the outer clip is greater than that of the inner clip, so that when the limit spring is compressed, the two clips can be relatively tightly held.

[0011] According to the above technical solution, preferably, the upper end of the vertical rod is fixedly connected with a short horizontal rod.

[0012] The present application also discloses a submerged plant collection method, based on the above submerged plant collection device, comprising the following steps:

[0013] S1. Insert the positioning tube into the bottom mud, and the positioning tube is at least 20cm into the soil;

[0014] S2. Press down the short horizontal rod to shrink the limit spring, and the two clips are tightly held and extend into the bottom mud along the positioning tube. After the two tightly held clips are inserted into the soil, the submerged plants are firmly grasped;

[0015] S3. By rotating the short crossbar, the two clips are slowly pulled up. When the two clips are exposed from the positioning tube, the limit spring restores the deformation and the lower ends of the two clips are closed to prevent the submerged plants from leaking out;

[0016] S4. Repeat steps S2 and S3 until all submerged plants are obtained.

[0017] The beneficial effects of the present invention are:

[0018] The invention is simple, convenient, time-saving and labor-saving to operate, reduces costs and greatly improves efficiency. Through the positioning cylinder, 2-3 repeated operations can be performed with the two clamps tightly clamped, so that all submerged plants in a fixed area can be effectively pulled up and part of the fetal mud can be retained after taking them out, thereby ensuring the integrity and freshness of the submerged plant seedlings. It is used for obtaining submerged plants in water ecological restoration projects in deeper water bodies, can avoid manual diving operations, and reduce manual risks.

Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the invention.

[0024] In the description of the invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the invention.

[0025] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Embodiment 1: As shown in the figure, the present invention includes a positioning cylinder 1 and a device body, wherein the device body includes two mutually adapted clips, a limit spring 6 connected to the upper part of the two clips, two movable rods 7 movably connected to the upper ends of the two clips, and a vertical rod 9 movably connected to the two movable rods 7, wherein the upper end of the vertical rod 9 is fixedly connected to a horizontal short rod 10. In this example, the positioning cylinder 1 preferably adopts a customized steel cylinder with a diameter of 400mm and a thickness of 3.7mm, and the vertical rod 9 and the horizontal short rod 10 adopt a DN50 hot-dip galvanized steel pipe with a thickness of 3.0mm to ensure a certain strength and hardness without deformation.

[0027] Through the interaction between the limit spring 6 and the clip, the limit spring 6 is in a natural state, and the spacing between the upper ends of the two clips is greater than the spacing between the lower ends of the two clips. When the two clips are inserted into the positioning tube 1, the limit spring 6 is compressed, so that the two clips are relatively tightly held. Specifically, in this example, the positioning tube 1 and the bottom ends of the two clips after being tightly held are both provided with a conical structure, which is convenient for insertion into the bottom mud, wherein the lower edge of the horizontal projection of the clip is an arc. In addition, preferably, the two clips are respectively an inner clip 4 and an outer clip 11, and the arc length of the outer clip 11 is greater than that of the inner clip 4, so that when the limit spring 6 is compressed, the two clips can be relatively tightly held. In this example, the inner clip 4 and the outer clip 11 are preferably customized with Q235 iron sheets with a thickness of 5mm, an arc length diameter of 350mm for the inner clip 4, an arc length of 380mm for the outer clip 11, and a height of 100mm. The two clips with different arc lengths can be effectively tightly held, so that the opening is reduced to achieve the effect of grabbing mud.

[0028] The outer side of the positioning tube 1 is fixedly connected with an extension handle 2, which is used to insert the positioning tube 1 into the bottom mud of the water body. The extension handle 2 is preferably made of DN40 hot-dip galvanized steel pipe with a thickness of 3.0mm, so that it has greater strength and hardness during operation. Among them, one or two of the extension handle 2 and the vertical pole 9 are telescopic structures, which are not limited by the water depth. The telescopic structure includes a plurality of adjustment rods connected by internal thread joints 3. The ends of the adjustment rods are threadedly connected to the internal thread joints 3. The internal thread joints 3 are DN40 hot-dip galvanized joints with internal threaded teeth, which are matched with the adjustment rods.

[0029] Large movable rings 8 are respectively provided on both sides of the lower end of the vertical pole 9, and the vertical pole 9 is movably connected to the upper end of the movable rod 7 through the large movable rings 8. A small movable ring 5 is provided on the upper side of the clamp, and the clamp is movably connected to the lower end of the movable rod 7 through the small movable ring 5. Specifically, the small movable ring 5 is welded with a diameter of 5mm threaded steel to form a circular ring with a diameter of 20mm, connecting the movable rod 7 and the clamp for easy contraction, or a diameter of 10mm threaded steel is used to ensure a certain strength and hardness without deformation. The large movable ring 8 is welded with a diameter of 5mm threaded steel to form a circular ring with a diameter of 30mm, connecting the vertical pole 9 and the movable rod 7.

[0030] Embodiment 2: The present application also discloses a method for collecting submerged plants, based on the above-mentioned submerged plant collecting device, comprising the following steps:

[0031] S1. According to the water depth of the target water area, insert the positioning tube 1 into the bottom mud through the extended handle 2, and the positioning tube 1 is at least 20 cm into the soil and does not tilt after releasing the handle;

[0032] S2. Press down the short horizontal rod 10. Due to the limit of the positioning tube 1, the limit spring 6 contracts, the two clips hug and extend into the bottom mud along the positioning tube 1. After the two clips are hugged, they enter the soil about 100mm and then firmly grasp the submerged plants 12;

[0033] S3. By rotating the short crossbar, the two clips are slowly pulled up. When the two clips are exposed from the positioning tube 1, the limit spring 6 recovers its deformation and the lower ends of the two clips are closed to prevent the submerged plants 12 from leaking out, and finally the submerged plants 12 are uprooted;

[0034] S4. Repeat steps S2 and S3 until there are no submerged plant seedlings 12 for the last time, and it can be determined that all of them have been pulled out.

[0035] The invention is simple, convenient, time-saving and labor-saving to operate, reduces costs and greatly improves efficiency. Through the positioning cylinder, 2-3 repeated operations can be performed with the two clamps tightly clamped, so that all submerged plants in a fixed area can be effectively pulled up and part of the fetal mud can be retained after taking them out, thereby ensuring the integrity and freshness of the submerged plant seedlings. It is used for obtaining submerged plants in water ecological restoration projects in deeper water bodies, can avoid manual diving operations, and reduce manual risks.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
