TECHNICAL FIELD
[0001] The utility model relates to biological monitoring equipment technical field, concretely is portable sampler of aquatic organism monitoring. BACKGROUND
[0002] Aquatic organism monitoring refers to the collection and analysis of aquatic organisms such as animals and plants and microorganisms in water bodies to evaluate the health status of aquatic ecosystems. Through aquatic organism monitoring, water quality changes can be effectively tracked, pollution sources can be detected, and ecological risks can be assessed, thereby providing a scientific basis for water environment management. When conducting aquatic organism monitoring, biological samples in the water body are usually collected. Currently, the most common and traditional sampling tool is a dip net, which is widely used in aquatic organism sampling due to its simple structure and convenient operation. When in use, the staff can catch aquatic organisms in the water body by extending the net bag into the water through the hand-held handle. However, this tool also has certain limitations in actual application, such as the aquatic organisms caught easily escaping from the net bag.
[0003] The patent with publication number CN219205619U discloses a kind of aquatic organism sampler, including first frame, second frame, guide rod, pull rope, handle and quick push mechanism, net bag is connected on first frame, first connecting plate is fixedly connected on first frame, multiple guide rods are fixedly connected on first connecting plate, the end of multiple guide rods is jointly connected with second connecting plate, handle is fixedly connected on second connecting plate, the end of handle is closed, a piece of sliding plate is slidably arranged on multiple guide rods, second frame is fixed on sliding plate, net cloth is connected in second frame, pull rope is fixedly connected on sliding plate, quick push mechanism includes push rod and first compression spring, push rod is fixedly connected on sliding plate, push rod penetrates second connecting plate and is arranged in handle, first compression spring is abutted between the end of push rod and the closed end of handle, the end of handle away from second connecting plate is connected with locking mechanism that can lock push rod, the utility model can improve the convenience of collecting aquatic organisms.
[0004] Although the above-mentioned prior art adds a sliding plate, a pull rope and a quick push mechanism to the sampling device, it solves the problems of inconvenient operation and biological escape in part of the aquatic organism sampling process, and improves the fishing efficiency by pressing the swing arm to make the net bag close quickly, but there are still certain defects in actual operation. Since the swing arm is located near the end of the handle, when the sampler holds the handle and moves the hand, the swing arm may be accidentally touched, causing the push rod to move and the net bag to close accidentally. In addition, when sampling aquatic organisms at a long distance, the hand of the staff inevitably needs to move towards the end of the handle, which further increases the risk of misoperation, thereby affecting the smooth progress of the sampling work. Therefore, the operation mode of the prior art still has room for improvement in design, and in view of this, we propose a portable sampler for aquatic organism monitoring. Utility model content
