Description

Technical Field

[0001] This utility model relates to the field of fishery ecological resource collection technology, and in particular to a fishery ecological resource collection device. Background Technology

[0002] In fishery waters, the collection and detection of phytoplankton and planktonic organisms serve as the "bottom-level data entry point" for fishery ecological resource acquisition. By accurately collecting the distribution, species, and quantity of these microorganisms, we can trace upstream to changes in the resource quantity of economic organisms such as fish, and downstream to analyze the health status of the aquatic environment. Ultimately, this forms a complete data chain of "plankton-environment-fishery resources," providing scientific support for sustainable fishery development, ecological protection, and emergency management.

[0003] Fishery resource surveys mainly include fish population surveys and environmental data sampling. Existing fishery resource survey collection devices are generally either floating or towed submersible. Floating devices cannot collect samples at different depths below the water surface, nor can they understand the distribution of fishery resources at different depths. Towed submersible devices require the use of boats and other tools to achieve collection work at deeper locations, which is more cumbersome to operate.

[0004] The existing patent (publication number: CN221826544U) discloses a fishery resource collection device for ecological monitoring. This device, through the cooperation of a rotating mechanism, a rotating motor and a rotating shaft, can adjust the waterproof detection box in both horizontal and vertical directions. The detection distance of the waterproof detection box can be adjusted by extending and retracting an electric push rod, thereby improving the range of resource collection and the diversity of information.

[0005] To address the aforementioned issues, existing patents offer solutions. However, when sampling and testing fishery water resources, some existing methods only collect partial water samples through containers, which makes it inconvenient to capture and collect phytoplankton and plankton within the fishery water body, affecting the accuracy of subsequent fishery water resource testing and assessment.

[0006] Therefore, a fishery ecological resource collection device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a fishery ecological resource collection device that can solve the problem that when some existing methods of sampling and testing fishery water resources only collect a portion of the water sample through a container, it is inconvenient to capture and collect phytoplankton and plankton inside the fishery water body, which affects the accuracy of subsequent fishery water resource testing and judgment.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fishery ecological resource collection device, including a capture tube, a capture mechanism is provided inside the capture tube, a connecting ring is provided at the top of the capture tube, a primary filtration mechanism is provided at the top of the connecting ring, and a submersible pump is fixedly connected to the bottom of the capture tube;

[0009] The capturing mechanism includes a fixed frame, a fine filter screen, and a limiting ring. The fine filter screen is fixedly connected inside the fixed frame, and the limiting ring is fixedly connected to the inner wall of the capturing cylinder. The bottom of the fixed frame is in movable contact with the top of the limiting ring.

[0010] Preferably, the primary filtration mechanism includes a connecting frame, a coarse filter screen, and a fixing ring. The bottom of the fixing ring is fixedly connected to the top of the connecting ring, the coarse filter screen is fixedly connected inside the fixing ring, and the bottom of the connecting frame is fixedly connected to the top of the fixing ring.

[0011] Preferably, the inner wall of the connecting ring is threadedly connected to the surface of the capture cylinder, and anti-slip blocks are fixedly connected to the surface of the connecting ring. The number of anti-slip blocks is several and they are evenly distributed on the surface of the connecting ring.

[0012] Preferably, a guide cover is fixedly connected to the inner wall of the connecting ring, and the guide cover is flared.

[0013] Preferably, pull rings are fixedly connected to both sides of the top of the fixed frame.

[0014] Preferably, the bottom of the capture tube is fixedly connected to a support rod, and the number of support rods is four and symmetrically distributed at the bottom of the capture tube. The bottom of the support rod is fixedly connected to a counterweight block.

[0015] Preferably, the counterweight block is made of cast iron and is coated with anti-rust paint.

[0016] Preferably, a power cord is provided on the left side of the submersible pump.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up a capture mechanism with a fine filter screen fixed inside a fixed frame. When water flows through, the fine filter screen traps phytoplankton and plankton. The pull ring at the top of the fixed frame makes it easy to remove and clean. By controlling the continuous operation of the submersible pump, a large number of plankton and phytoplankton can be captured inside the capture tube, thereby improving the accuracy of subsequent ecological assessment of fishery water resources.

[0019] 2. This application sets up a primary filtration mechanism, with a coarse filter screen fixed inside the fixed ring. The bottom is connected to the connecting ring, and the top connecting frame is used for external binding. The coarse filter screen blocks larger impurities and small fish in the water, preventing them from entering the capture tube and affecting the capture of plankton and phytoplankton.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A fishery ecological resource collection device includes a capture tube 1, a capture mechanism 8 is provided inside the capture tube 1, a connecting ring 2 is provided at the top of the capture tube 1, a primary filtration mechanism 3 is provided at the top of the connecting ring 2, and a submersible pump 7 is fixedly connected to the bottom of the capture tube 1.

[0029] The capture mechanism 8 includes a fixed frame 801, a fine filter screen 802, and a limiting ring 803. The fine filter screen 802 is fixedly connected inside the fixed frame 801, and the limiting ring 803 is fixedly connected to the inner wall of the capture cylinder 1. The bottom of the fixed frame 801 is in contact with the top of the limiting ring 803.

[0030] In this embodiment: the connecting frame 301 is secured by an external connecting rope, and the submersible pump 7 is powered by an external mobile power supply via a power cord 4. The submersible pump 7 and the capture tube 1 are lowered to the required water depth via the connecting rope. When the submersible pump 7 is working, water carrying plankton and phytoplankton is continuously drawn into the capture tube 1 through the guide cover 10. The coarse filter 302 of the primary filtration mechanism 3 blocks large impurities and small fish, while the fine filter 802 of the capture mechanism 8 traps plankton and phytoplankton. By continuously working, the capture volume can be increased, thus improving the ecological balance of fishery water resources. To ensure accurate condition detection, after power failure, use the connecting rope to pull out the capture tube 1. The support rod 5 and counterweight block 6 stabilize the capture tube 1 in the water. Support the capture tube 1 on the shore, then rotate the connecting ring 2 to open the capture tube 1 and pour out the water and captured objects inside. Hold the pull ring 9 to pull out the fixing frame 801 and fine filter screen 802 to completely remove plankton and phytoplankton, facilitating the detection of fishery water resources. The large-scale capture of plankton and phytoplankton inside the fishery water body makes it easier to accurately determine whether the fishery water body meets the ecological standards.

[0031] Specifically, such as Figure 3 As shown, the primary filtration mechanism 3 includes a connecting frame 301, a coarse filter screen 302, and a fixing ring 303. The bottom of the fixing ring 303 is fixedly connected to the top of the connecting ring 2. The coarse filter screen 302 is fixedly connected inside the fixing ring 303. The bottom of the connecting frame 301 is fixedly connected to the top of the fixing ring 303.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the inner wall of the connecting ring 2 is threadedly connected to the surface of the capture cylinder 1, and anti-slip blocks 11 are fixedly connected to the surface of the connecting ring 2. There are several anti-slip blocks 11, which are evenly distributed on the surface of the connecting ring 2.

[0033] Specifically, such as Figure 1 and Figure 4 As shown, a guide cover 10 is fixedly connected to the inner wall of the connecting ring 2, and the guide cover 10 is flared.

[0034] In this embodiment: the fixing ring 303 in the primary filtration mechanism 3 is fixedly connected to the connecting ring 2. The coarse filter screen 302 can block large impurities and small fish in the water, preventing them from entering the capture tube 1 and affecting the collection of plankton and phytoplankton. The connecting ring 2 is threadedly connected to the capture tube 1, which is convenient for disassembly and assembly. The anti-slip block 11 on its surface can increase friction and facilitate rotation operation. The inner wall funnel-shaped guide cover 10 can guide water to flow in, improve suction efficiency, and the bottom opening is small, which can prevent plankton from escaping from the capture tube 1.

[0035] Specifically, such as Figure 2 As shown, pull rings 9 are fixedly connected to both sides of the top of the fixed frame 801.

[0036] Specifically, such as Figure 1 As shown, the bottom of the capture tube 1 is fixedly connected to a support rod 5. There are four support rods 5, which are symmetrically distributed at the bottom of the capture tube 1. The bottom of the support rod 5 is fixedly connected to a counterweight block 6.

[0037] In this embodiment: the top pull ring 9 of the fixed frame 801 makes it easy to pull out the fixed frame 801 and the fine filter screen 802 by hand, so as to thoroughly clean the captured plankton and algae. The four support rods 5 and the counterweight block 6 at the bottom of the capture tube 1 can increase the weight of the capture tube 1, prevent the capture tube 1 from moving when the submersible pump 7 is working, and the counterweight block 6 can stably support the capture tube 1 on the shore.

[0038] Specifically, such as Figure 1 As shown, the counterweight block 6 is made of cast iron and is coated with anti-rust paint.

[0039] Specifically, such as Figure 1 As shown, a power cord 4 is installed on the left side of the submersible pump 7.

[0040] In this embodiment: the counterweight block 6 is made of cast iron and is treated with anti-rust to prevent the counterweight block 6 from rusting, and the power cord 4 on the left side of the submersible pump 7 is convenient for connecting to an external mobile power supply.

[0041] Working Principle: The submersible pump 7 is powered by an external connecting rope and a connecting frame 301. Power is supplied to the submersible pump 7 via a power cord 4. The submersible pump 7 is lowered to the required depth in the fishery water using the connecting rope. When the submersible pump 7 is working, a large amount of water carrying phytoplankton and plankton is drawn into the capture tube 1 through the funnel-shaped guide hood 10. The coarse filter 302 of the primary filtration mechanism 3 blocks larger impurities and small fish, preventing them from entering the capture tube 1. The water continues to flow through the fine filter 802 of the capture mechanism 8, trapping the phytoplankton and plankton within the capture tube 1. The filtered water is then discharged. This increases the capture volume of plankton and algae, improving the accuracy of fishery water resource ecological status monitoring. After the submersible pump 7 is powered off and stops working, some water and captured material remain in the capture tube 1. The capture tube 1 and submersible pump 7 are then pulled to the shore using the external connecting rope. The four support rods 5 at the bottom of the capture tube 1 and the cast iron, rust-proofed counterweight block 6 provide stable support for the capture tube 1. When the water is near the shore and inside the water body, the weight of the capture tube 1 can be increased to prevent the capture tube 1 from moving around due to the thrust of the submersible pump 7. Then, the connecting ring 2 is rotated. Since the connecting ring 2 is threadedly connected to the capture tube 1, the capture tube 1 can be opened to pour out the water inside and the captured plankton and algae. By holding the pull ring 9 at the top of the fixing frame 801, the fixing frame 801 and the fine filter screen 802 can be pulled out from the capture tube 1, which is convenient for thoroughly cleaning the plankton and algae for testing. A large number of plankton and algae are captured inside the fishery water body, which makes it easier to more accurately determine whether the fishery water body meets the ecological standards. This solves the problem that when some existing fishery water resources are sampled and tested, only a part of the water sample is collected through a container, which is inconvenient to capture and collect the plankton and algae inside the fishery water body, affecting the accuracy of subsequent fishery water resources testing and judgment. It should be noted that the submersible pump 7 is a mature technology that has been published. Its basic waterproof mechanism will not be elaborated here.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
