Anchor-shaped portable field aquatic plant collector

Abstract

The utility model relates to the technical field of aquatic plant collecting devices, in particular to an anchor-shaped portable field aquatic plant collector, which can be connected with a mooring rope to collect aquatic plants distant in water, and a plurality of main anchor hooks and auxiliary anchor hooks are arranged at the bottom of a central shaft along the circumferential direction, so that the field aquatic plant collecting device can be used for collecting the aquatic plants. The main anchor hook and the auxiliary anchor hook form a pocket-shaped structure on the periphery of the central shaft, so that aquatic plants with different sizes can be collected. As the tail end of the main anchor hook and the tail end of the auxiliary anchor hook are staggered up and down on the periphery of the central shaft, the main anchor hook is supported in sludge and the auxiliary anchor hook is suspended in water when the anchor hook is located underwater, the resistance of the collector moving forwards underwater is reduced when a mooring rope is pulled, and the anchor hook can be pulled more conveniently; the main anchor hook and the auxiliary anchor hook which are staggered up and down can hook different parts of the rattan of the aquatic plant, so that greater pulling force can be applied to the whole aquatic plant, and the main anchor hook and the auxiliary anchor hook are prevented from intensively hooking the same part of the aquatic plant to cause snap.

Description

Technical Field

[0001] This utility model relates to the technical field of aquatic plant collection tools, specifically to an anchor-shaped portable field aquatic plant collector. Background Technology

[0002] In scientific research and ecological protection of water resources or aquatic plants, it is sometimes necessary to collect aquatic plants. By collecting aquatic plant samples, we can study their growth habits, distribution range, ecological adaptability, etc., and they can also be used to monitor the health status of aquatic ecosystems and detect water pollution and other problems in a timely manner.

[0003] During the collection of aquatic plants, those near the shore can be manually retrieved using nets. However, some aquatic plants are located far from the shore, requiring a retrieval boat to reach the area and collect them using nets and rakes, which is less convenient. Furthermore, since aquatic plants are rooted underwater, pulling too hard with nets or rakes can cause them to break, making it difficult to collect intact plants. Utility Model Content

[0004] The present invention aims to provide an anchor-shaped portable field aquatic plant collector to collect aquatic plants at a distance in the water, and to pull them lightly on the bottom of the water, and to hook different parts of the aquatic plants to avoid breaking them.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] Design an anchor-shaped portable field aquatic plant collector, including a central shaft. Multiple main anchor hooks and secondary anchor hooks are arranged circumferentially at the bottom of the central shaft. The secondary anchor hooks are distributed between adjacent main anchor hooks. One end of each main anchor hook and secondary anchor hook is fixed to the bottom of the central shaft, and the other end extends upward and to the side of the bottom of the central shaft. The end of the secondary anchor hook is lower than the end of the main anchor hook, so that the ends of the main anchor hooks and the ends of the secondary anchor hooks are staggered around the periphery of the central shaft.

[0007] Furthermore, it also includes at least one retaining ring, which contacts each of the main anchor hooks and secondary anchor hooks, and the main anchor hooks and secondary anchor hooks are respectively connected to the retaining ring.

[0008] Furthermore, the ends of the main anchor hook and the auxiliary anchor hook are pointed, and silicone sleeves are respectively fitted onto the pointed ends of the main anchor hook and the auxiliary anchor hook.

[0009] Furthermore, the main anchor hook is arc-shaped, and the main anchor hook includes a continuous downward extension section and an upward extension section, the downward extension section extending downward from the lower end of the central axis; the secondary anchor hook is arc-shaped with a bending direction consistent with the main anchor hook.

[0010] Furthermore, the lower end of the central shaft is provided with an enlarged diameter section, and the heads of the main anchor hook and the auxiliary anchor hook are welded to the bottom surface of the enlarged diameter section.

[0011] Furthermore, the end of the secondary anchor hook is located halfway up the main anchor hook.

[0012] Furthermore, a connecting ring for connecting cables is provided at the top of the central shaft.

[0013] Furthermore, the main anchor hook and the secondary anchor hook gradually taper from the head end to the tail end.

[0014] Furthermore, the central shaft has a diameter of 10mm and a length of 30cm; the main anchor hook has a length of 20cm, and the secondary anchor hook has a length of 16cm; the fixing ring is formed by welding together stainless steel bars with a diameter of 3mm.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: This anchor-shaped portable aquatic plant collector can be connected to a cable to collect aquatic plants at a distance in the water. By setting multiple main and secondary anchor hooks circumferentially at the bottom of the central axis, the main and secondary anchor hooks form a pocket-like structure around the central axis. The main and secondary anchor hooks can hook onto vine-like aquatic plants, while smaller aquatic plants can fall into the pocket-like structure formed by the main and secondary anchor hooks, thus enabling the collection of aquatic plants of different sizes. Because the ends of the main and secondary anchor hooks are staggered around the central axis, when underwater, the main anchor hook is supported in the silt, while the secondary anchor hook is suspended in the water. When the cable is pulled, the resistance of the collector moving forward underwater is reduced, making it easier to pull. Furthermore, the staggered main and secondary anchor hooks can hook onto different parts of the aquatic plant vines, which helps to apply greater pulling force to the aquatic plant as a whole and avoids the main and secondary anchor hooks from concentrating on the same part of the aquatic plant, which could lead to breakage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Unless otherwise specified, the unit modules, components, structures, mechanisms, or sensors involved in the following embodiments are all conventional commercially available products. In the description of this application, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first," "second," etc., involved in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] In one embodiment, an anchor-shaped portable field aquatic plant collector is provided, such as... Figure 1-3 As shown, the anchor-shaped portable aquatic plant collector includes a central shaft 1, which is a main support rod made of metal. Multiple main anchor hooks 2 and secondary anchor hooks 3 are arranged circumferentially at the bottom of the central shaft 1. The main anchor hooks 2 and secondary anchor hooks 3 form a hook-like structure with the central shaft 1 to hook aquatic plants. Both the main anchor hooks 2 and secondary anchor hooks 3 are made of metal; for example, the central shaft 1, main anchor hooks 2, and secondary anchor hooks 3 can all be made of stainless steel to prevent deformation under high tensile force. The main anchor hooks 2 are longer than the secondary anchor hooks 3. Secondary anchor hooks 3 are distributed between adjacent main anchor hooks 2. In this embodiment, four main anchor hooks 2 are evenly distributed around the perimeter of the central shaft 1, and two secondary anchor hooks 3 are evenly distributed between adjacent main anchor hooks 2. That is, the anchor-shaped portable aquatic plant collector has four main anchor hooks 2 and eight secondary anchor hooks 3 around the central shaft 1.

[0025] like Figure 1-3As shown, one end of the main anchor hook 2 and the auxiliary anchor hook 3 is fixed to the bottom of the central shaft 1. In this embodiment, the first ends of the main anchor hook 2 and the auxiliary anchor hook 3 are welded to the bottom of the central shaft 1. The other ends of the main anchor hook 2 and the auxiliary anchor hook 3 extend upwards towards the bottom side of the central shaft 1. The end of the auxiliary anchor hook 3 is lower than the end of the main anchor hook 2. This means that when viewed from the side, the end of the auxiliary anchor hook 3 is lower than the end of the main anchor hook 2. This makes the ends of the main anchor hook 2 and the ends of the auxiliary anchor hook 3 staggered around the perimeter of the central shaft 1.

[0026] The anchor-shaped portable aquatic plant collector is used as follows: A cable is attached to the top of the collector's central axis 1, and the collector is thrown into the water where the aquatic plants are located. Under its own weight, the collector will sink to the bottom of the water. The main anchor hook 2 and the secondary anchor hook 3 will work together to catch the vines of the aquatic plants. Then, the collector is pulled back to the shore by the cable. This process can be repeated many times to collect the required types and quantities of aquatic plants.

[0027] This anchor-shaped portable aquatic plant collector has the following advantages: By circumferentially arranging multiple main anchor hooks 2 and secondary anchor hooks 3 at the bottom of the central axis 1, the main anchor hooks 2 and secondary anchor hooks 3 form a pocket-like structure around the central axis 1. The main anchor hooks 2 and secondary anchor hooks 3 can hook onto vine-like aquatic plants, while smaller aquatic plants can fall into the pocket-like structure formed by the main anchor hooks 2 and secondary anchor hooks 3, thus enabling the collection of aquatic plants of different sizes. Because the ends of the main anchor hooks 2 and secondary anchor hooks 3 are staggered around the central axis 1, when underwater, the main anchor hooks 2 are supported in the silt, while the secondary anchor hooks 3 are suspended in the water. This reduces the resistance of the collector moving underwater when the cable is pulled. Furthermore, the staggered main anchor hooks 2 and secondary anchor hooks 3 can hook onto different parts of the aquatic plant vines, which helps to apply greater pulling force to the aquatic plant as a whole and avoids the main anchor hooks 2 and secondary anchor hooks 3 concentrating on the same part of the aquatic plant, which could lead to breakage.

[0028] Furthermore, in another embodiment, such as Figure 1-3 As shown, the anchor-shaped portable aquatic plant collector also includes two fixing rings 4. The two fixing rings 4 are of different sizes and are distributed vertically on the inner sides of the main anchor hook 2 and the auxiliary anchor hook 3. The two fixing rings 4 are in contact with each of the main anchor hook 2 and the auxiliary anchor hook 3. The main anchor hook 2 and the auxiliary anchor hook 3 are fixedly connected to the fixing rings 4. In this embodiment, the two fixing rings 4 are made of stainless steel ribs. The two fixing rings 4 are welded to the inner sides of each of the main anchor hook 2 and the auxiliary anchor hook 3. By setting the two fixing rings 4, the main anchor hook 2 and the auxiliary anchor hook 3 are more stable and form a mesh structure to prevent aquatic plants from falling out.

[0029] Furthermore, the central shaft 1 of the data collector has a diameter of 10mm and a length of 30cm; the main anchor hook 2 is 20cm long, and the secondary anchor hook 3 is 16cm long; the fixing ring 4 is formed by welding 3mm diameter stainless steel bars. The lengths of the main anchor hook 2 and the secondary anchor hook 3 refer to the overall length of their extension paths. This type of data collector is lightweight and meets the data collection requirements.

[0030] Furthermore, in another embodiment, the ends of the main anchor hook 2 and the secondary anchor hook 3 of the anchor-shaped portable field aquatic plant collector are pointed, and silicone sleeves are respectively fitted onto the pointed ends of the main anchor hook 2 and the secondary anchor hook 3. Combined with Figure 4 As shown, taking the main anchor hook 2 as an example, the silicone sleeve 5 fitted at its tail end has a blind hole in the middle. The silicone sleeve 5 can be tightly fitted at the end of the main anchor hook 2 to prevent the tip from injuring people. Protective sleeves of different materials such as rubber sleeves can also be used.

[0031] like Figure 1-3 As shown, in this embodiment, the end of the secondary anchor hook 3 is located at the mid-section of the main anchor hook 2. The mid-section refers to the middle position in the height direction from the side view of the main anchor hook 2. This staggered shape allows the secondary anchor hook 3 to hook onto the vines of aquatic plants without contacting the silt on the bottom of the water. The main anchor hook 2 and the secondary anchor hook 3 gradually taper from the head to the tail to reduce weight while maintaining strength.

[0032] Furthermore, in another embodiment, such as Figure 3 As shown, the main anchor hook 2 of this anchor-shaped portable aquatic plant collector is arc-shaped, comprising a continuous downward extension section 21 and an upward extension section 22. The downward extension section 21 extends downward from the lower end of the central axis 1, and the upward extension section 22 extends upward from the end of the downward extension section 21. The secondary anchor hook 3 is arc-shaped with a curvature consistent with the main anchor hook 2. This structure allows for a large internal space within the pocket-like structure formed by the main anchor hook 2 and the secondary anchor hook 3, accommodating the collected aquatic plants.

[0033] Furthermore, in another embodiment, such as Figure 1 As shown, the lower end of the central shaft 1 of the anchor-shaped portable field aquatic plant collector is provided with an enlarged diameter section 11 to increase the bottom welding surface, so that the heads of the main anchor hook 2 and the auxiliary anchor hook 3 can be welded to the bottom surface of the enlarged diameter section 11 at different positions.

[0034] Furthermore, in another embodiment, such as Figure 1-3 As shown, the anchor-shaped portable field aquatic plant collector has a connecting ring 6 at the top of the central shaft 1 for connecting a cable. The top of the central shaft 1 has a hole through which the connecting ring 6 passes, and the connecting ring 6 is inserted into the hole.

[0035] Based on the above embodiments, it can be seen that this anchor-shaped portable aquatic plant collector has multiple main anchor hooks 2 arranged around the bottom perimeter of the central shaft 1. Two secondary anchor hooks 3 are added between every two adjacent main anchor hooks 2. The secondary anchor hooks 3 are slightly shorter and thinner than the main anchor hooks 2. A cable is fixedly connected via a connecting ring at the top of the central shaft 1. During use, one hand can hold one end of the cable, and the main collector can be thrown into the water at a distance. After sinking to the bottom, the cable can be pulled, and the collector's own weight will allow it to probe into the bottom sediment and collect the aquatic plants. After use, silicone sleeves can be put on the hook tips to prevent damage, and the cable can be coiled up. This collector is easy to carry, saves space, and can collect aquatic plants from deep water at a distance.

[0036] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various specific parameters in the above embodiments can be changed without departing from the spirit of the invention, resulting in multiple specific embodiments. These are all common variations of the present invention and will not be described in detail here.
