Problems solved by technology

[0003] At present, there are few aquatic insect collection devices, and some collection devices with power supply are not practical for long-term use in the field. Ordinary collection water nets are easy to escape after aquatic insects enter, and the collection efficiency is low. Multiple collections are required, and the time cost is high.

Embodiment 1

[0024] Such as figure 1 , 2 The auxiliary device for collecting aquatic insects shown includes a box body 1, and a fixed rod 2 is fixedly installed around the upper end of the box body 1, and a floating ball 3 is installed on the outside of the fixed rod 2. By installing the floating ball 3, the box body 1 Floats under the water surface to collect insects in the water; the inside of the box body 1 is fixedly installed with a first partition 4 and a first inlet 5, the first inlet 5 is funnel-shaped, and the larger end communicates with the outside to facilitate the entry of insects , the inside of the first partition 4 is used to place bait to attract aquatic insects, thereby attracting aquatic insects to enter; the first partition 4 is provided with a second inlet 6 and a first groove 7 matched with the first inlet 5 By setting the first groove 7, it is convenient for aquatic insects to enter between the box body 1 and the first partition net 4, which greatly reduces the poss...

Embodiment 2

[0029] This embodiment is further optimized on the basis of embodiment 1, as image 3 , 4 As shown, the upper end of the box body 1 is fixedly equipped with a connecting rod 12, and the upper end of the connecting rod 12 is fixedly installed with a cover body 13. The winged aquatic insects are collected, and the upper cover 14 is used to place bait to improve the collection efficiency; the third inlet 15 is fixedly installed at the bottom of the cover body 13, and the third inlet 5 is funnel-shaped, and the small end of the opening faces inward; 13 is fixedly installed with a second partition 16 inside. The second partition 16 is provided with a fourth inlet 17 and a second groove 18 matching with the third inlet 15. By setting the second groove 18 to match the third The inlet 15 reduces the possibility of aquatic insects escaping, and cooperates with the fourth inlet 17 to further increase the possibility of preventing aquatic insects from escaping, so that the aquatic insec...

Abstract

The invention relates to an auxiliary device for collecting aquatic insects, and belongs to the technical field of collection devices. The auxiliary device comprises a box body, wherein the periphery of the upper end of the box body is fixedly provided with fixing rods, the outer portions of the fixing rods are provided with floating balls, the inner portion of the box body is fixedly provided with a first screen and a first inlet, the first screen is provided with a second inlet and a first groove cooperating with the first inlet, and the bottom of the box body is provided with a bottom cover rotationally connected with the bottom of the box body. The auxiliary device for collecting the aquatic insects has the advantages that the box body with two-layer funnel-shaped inlets traps and collects the aquatic insects, the collection efficiency is high, the possibility is reduced that the aquatic insects entering the interior escape, a cover body with an adjustable distance arranged above the box body collects the aquatic insects on the water surface, the design of the two-layer funnel-shaped inlets avoids the escape of the aquatic insects entering the interior, the collection depth of the box body is controlled through the cooperation with the addable floating balls, the structure is simple, the operation is convenient, and the collection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of collecting devices, in particular to an auxiliary device for collecting aquatic insects. Background technique [0002] Aquatic insects are one of the food for economic fish, and their larvae can be used in water quality monitoring. Aquatic insect fossils are of great significance to the restoration of aquatic environments in ancient times. Aquatic insects are mainly divided into winged species that live on the water and wingless species in the water. Underwater wingless species include planktonic aquatic insects, which can freely suspend, swim and float on the water surface. As people pay more and more attention to aquatic insects, their research is also deepening, and they need to be collected before research. [0003] At present, there are few aquatic insect collection devices, and some collection devices with power supply are not practical for long-term use in the field. Ordinary collection water net...
