Description

Technical Field

[0001] The utility model relates to the technical field of water ecological management and aquatic plant collection equipment, in particular to a submerged plant collection device. Background Art

[0002] The collection of aquatic plants is an important activity involving aquatic ecology and environmental monitoring. Through the collection and research of aquatic plants, scientists can gain a deep understanding of the operating mechanism of aquatic ecosystems and provide a scientific basis for ecological protection and environmental governance.

[0003] In order to improve the efficiency and accuracy of aquatic plant collection, reduce the manpower and material consumption in the collection process, and especially to enhance the safety of the collection process, the prior art proposes a variety of special collector equipment for improving the aquatic plant collection process, such as clip-type aquatic plant collectors, mechanical grabbing aquatic plant collectors, ship-borne aquatic plant collectors, etc.

[0004] However, the existing technologies have deficiencies or defects in actual use. The clip-type aquatic plant collector often needs to manually operate the clip to clamp the aquatic plants and then lift them. Although the solution is simple and low-cost, the operation is cumbersome and inefficient; the mechanical grabbing aquatic plant collector grabs the aquatic plants through a control mechanism, which can be considered as a targeted improvement on the manually operated clip-type aquatic plant collector. It is slightly more efficient than the clip-type collector, but is still limited by the flexibility and operation accuracy of the mechanical device, and the collection effect is not ideal; the ship-borne aquatic plant collector is a special equipment installed on the ship, which collects aquatic plants through the movement of the ship and the operation of the collector. This method is only suitable for large-area waters suitable for ship navigation. It is obviously limited by the accessibility of the ship and the design of the collector, and cannot meet the aquatic plant collection needs in a variety of different environments.

[0005] It can be seen from this that due to the complex growth environment and diverse species of aquatic plants, the collection methods of existing technologies generally have the problems of low efficiency, poor precision, large consumption of manpower and material resources, and may also pose personal safety hazards to collectors during use. Utility Model Content

[0006] In order to address the deficiencies in the prior art, the utility model proposes a submerged plant collection device, which installs an electric device to cut the part of the submerged plants above the bottom mud and performs the collection operation at the same time, thereby completing the biomass collection while obtaining submerged, floating leaves, and floating aquatic plants. The operation process is convenient and effectively reduces manual intervention, which can effectively save manpower and material resources in the process of aquatic plant collection and improve the collection efficiency.

[0007] In order to achieve the above objectives, the technical solutions adopted by the utility model include:

[0008] A submerged plant collection device, characterized in that it comprises a cutting base, a support frame and a cover net;

[0009] The cutting base comprises a main frame of a rectangular body structure and a cutting assembly arranged on the main frame, wherein the cutting assembly is controllably and freely displaced linearly from a first short side of the main frame to a second short side along the long side of the main frame through a sliding mechanism, and a bottom net is further arranged between the cutting assembly and the first short side, and when the cutting assembly is displaced to the second short side, the bottom net is unfolded to cover the bottom side of the main frame;

[0010] The support frame is detachably mounted on the top side of the main frame;

[0011] The cover net is sleeved and installed on the support frame. When the bottom net is unfolded to cover the bottom side of the main frame, the cover net and the bottom net are combined to form a first space for accommodating aquatic plants.

[0012] Furthermore, the sliding mechanism includes a group of rack rails installed on the long sides of both sides of the main frame and a displacement gear group installed on the cutting assembly to match and engage with the rack rails. The displacement gear group is driven to rotate by a first motor and engages with the rack rails to drive the cutting assembly to perform linear displacement along the long sides of the main frame.

[0013] Furthermore, anti-slip rods corresponding to the rack rails are provided on both long sides of the main frame, and sliding wheels corresponding to the anti-slip rods are provided on the cutting assembly. When the cutting assembly performs a linear displacement along the long sides of the main frame, the sliding wheels abut against the anti-slip rods to provide vertical limitation for the cutting assembly.

[0014] Further, the cutting assembly includes a band saw driven by a second motor.

[0015] Furthermore, baffles protruding toward the second short side are provided at both ends of the cutting assembly, and when the cutting assembly performs a linear displacement along the long side of the main frame, the baffles prevent the aquatic plants from escaping from the cutting base.

[0016] Furthermore, the support frame includes a plurality of support tubes of switchable lengths which are installed in combination to form first spaces of various sizes.

DETAILED DESCRIPTION

[0026] In order to more clearly understand the content of the utility model, it will be described in detail with reference to the drawings and embodiments.

[0027] like Figures 1 to 6 The schematic diagram of the structure of a preferred embodiment of the submerged plant collecting device of the utility model is shown, which includes a cutting base 1, a support frame 2 and a cover net 3, wherein the attached Figure 1 To Attachment Figure 3 The specific structure of the cutting base 1 is mainly shown, and the support frame 2 and the cover net 3 are not included. Figure 1 To Attachment Figure 3 Displayed in.

[0028] The main body of the cutting base 1 is composed of a main frame 11 of a rectangular structure and a cutting assembly 12 installed on the main frame 11. Among them, the main frame 11 can preferably have a longer side and a shorter side, or artificially define the "longer side" and the "shorter side" on the square structure, so that the cutting assembly 12 can be correctly installed and perform linear displacement along the longer side of the main frame 11. During use, the main frame 11 is used to sink into the water to the depth required for aquatic plant collection, such as contacting the bottom of the water, and used as a calibration for the effective area for collection and cutting. Preferably, since the bottom side of the main frame 11 may directly contact the bottom mud of the water, it can preferably have a structure with a large gap with the bottom mud, so as to minimize the aquatic plants accumulated at the bottom of the device during the sinking process of the device.

[0029] In particular, the cutting assembly 12 includes a band saw driven by the second motor 15, and the cutting assembly 12 is controllably and freely displaced linearly from the first short side 111 of the main frame 11 to the second short side 112 along the long side of the main frame 11 through a sliding mechanism. The sliding mechanism includes a set of rack rails 113 installed on both long sides of the main frame 11 and a displacement gear set 121 installed on the cutting assembly 12 and matched with the rack rails 113. The displacement gear set 121 is driven to rotate by the first motor 14 and engages with the rack rails 113 to drive the cutting assembly 12 to perform linear displacement along the long side of the main frame 11. And preferably, in order to provide the necessary vertical limiting effect for the cutting assembly 12, the long sides of both sides of the main frame 11 are also provided with anti-slip rods 114 corresponding to the rack rails 113, and the cutting assembly 12 is also provided with sliding wheels 122 corresponding to the anti-slip rods 114. When the cutting assembly 12 performs linear displacement along the long sides of the main frame 11, the sliding wheels 122 abut against the anti-slip rods 114 to provide vertical limiting for the cutting assembly 12. In practical applications, the band saw can use a suitable tensioning mechanism under the existing technology to assist in adjusting the tightness of the band saw to ensure that the band saw remains stable during operation. At the same time, it is easy to understand that since the device needs to be operated underwater, the first motor 14 and the second motor 15 should both use products with corresponding waterproof functions, and the main components in the device should also preferably be made of materials such as stainless steel to enable it to have the necessary waterproof and rust-proof capabilities. On the other hand, in order to reduce the friction loss between the moving parts, suitable drag-reducing gaskets, drag-reducing washers, etc. can be preferably added between the moving parts that contact each other.

[0030] In particular, a bottom net 13 is further provided between the cutting assembly 12 and the first short side 111. When the cutting assembly 12 is displaced to the second short side 112, the bottom net 13 is unfolded to cover the bottom side of the main frame 11. The bottom net 13 can be made of a flexible material so that it can be freely contracted and expanded, or it can be made of a mesh material with a pleated leaf structure or the like as required, and has the necessary contraction and expansion capabilities.

[0031] Preferably, baffles 123 protruding toward the second short side 112 are provided at both ends of the cutting assembly 12. When the cutting assembly 12 performs a linear displacement along the long side of the main frame 11, the baffles 123 prevent the aquatic plants from escaping from the cutting base 1.

[0032] The support frame 2 is detachably mounted on the top side of the main frame 11. For example, a pre-set tube combination can be used to form the support frame 2. In particular, a combination of support tubes of various lengths can be preset to form a support frame 2 of various sizes. A length-adjustable tube combination can also be used. When the support frame 2 is mounted on the main frame 11, the cover net 3 is sleeved and installed on the support frame 2, and is combined with the main frame 11 to form a "pocket" structure with an open bottom (such as the attached Figure 6 As shown in FIG. 1 , when the bottom net 13 is unfolded to cover the bottom side of the main frame 11, the cover net 3 and the bottom net 13 are combined to form a first space for accommodating aquatic plants. It is easy to understand that when different sizes of support frames 2 are used, first spaces of different sizes will be formed accordingly, thereby adapting to the collection needs of aquatic plants of different environments and types.

[0033] Preferably, in order to prevent the collected plants from leaking out of the first space, the bottom net 13 may have a structure with a smaller mesh size than the cover net 3 .

[0034] When using the submerged plant collecting device of the preferred embodiment, first assemble the support frame 2 as needed, unfold the cover net 3 (usually foldable for storage) and put it on the support frame 2, and then sink the entire device into the water at a predetermined collecting position. At this time, the cutting assembly 12 should be on the first short side 111 side of the main frame 11, so that the bottom opening of the device (such as the attached Figure 4 When the device descends to a predetermined collection height position (for example, the bottom side of the main frame 11 contacts the bottom of the water), the aquatic plants to be collected enter the cover net 3 through the bottom opening. At this time, the first motor 14 and the second motor 15 are controlled to perform a driving operation, so that the cutting assembly 12 cuts the aquatic plants while linearly moving toward the second short side 112, and at the same time drives the bottom net 13 to gradually expand and close the bottom opening (as shown in the attached figure). Figure 5When the cutting assembly 12 is displaced to the second short side 112, the cutting operation is completed at the same time, and the bottom net 13 is fully unfolded and the bottom opening is closed, forming a first space for accommodating the cut aquatic plants. At this time, the device can be lifted out of the water as a whole. During the process, the water in the first space leaks out from the pores of the bottom net 13 and the cover net 3, and only the required aquatic plants are retained in the first space.

[0035] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
