Aquatic insect torrent trapping net

Abstract

The invention discloses an aquatic insect torrent trapping net and belongs to the technical field of traps. The aquatic insect torrent trapping net consists of a net handle, a bracket support ring, a net opening iron ring, a net body, a net bottom connection ring, a net bottom collection bag, a net bottom stone outlet, a support frame, an inclined support rod, a fixing rod, a horizontal bracket, an elastic support rod, a frame support rod, an opening tying band, collection bag opening meshes, a ring fixing wedge, a support ring clamping piece and a movable connector. The aquatic insect torrent trapping net is characterized in that the net bottom collection bag is a cylindrical bag and comprises an inner-layer wall and an outer-layer wall, and the outer-layer wall is made of a piece of commercially available cotton fiber cloth; the inner-layer wall is net-shaped, the middle is separated by the opening tying band, mesh diameters of the part in front of the opening tying band are in a range of 1-2 cm and are called the collection bag opening meshes, and mesh diameters of the part behind the opening tying band are in a range of 0.1-0.2 cm; the net opening iron ring, the support frame, the fixing rod, the horizontal bracket, the elastic support rod and the frame support rod form a triangular guide bracket together. The aquatic insect torrent trapping net is simple to manufacture, diversified in function, high in operability, low in cost and obvious in effect.

Description

technical field [0001] The invention relates to a torrent catch net for aquatic insects, belonging to the technical field of catchers. Background technique [0002] Nets used to catch insects that fly fast, jump and swim in water are commonly known as insect nets. Due to the differences in the habits and living environments of different insects, different insect nets should be used according to the actual catching operations. Insect nets can generally be divided into three types: nets, nets and water nets. Water nets are designed for catching aquatic insects. The materials used to make water nets are required to be strong and durable, and have good water permeability, usually made of spun yarn or linen. The specifications of the net circle of the water net are the same as those of the insect net. The feature is that the net bag is shorter and has a basin-bottom shape, and the net handle is longer. The known water nets have a better effect of catching aquatic insects, but...

Problems solved by technology

[0003] In order to overcome the problem that currently known water nets cannot automatically avoid or block stones trapped in the water flow and efficiently capture aquatic insects living at the bottom of the torrent, the present invention provides a net for capturing aquatic insect torrents. The catch net uses the triangular guide bracket formed by the iron ring of the net mouth, the support frame, the fixed rod, the horizontal bracket, the elastic strut, and the frame strut to guide the larger stones to move to both sides and prevent the larger stones from entering the net. body; with the help of the momentum of the water flow, the small stones in front of the belt are plunged into the bottom of the mesh surrounded by the belt, and the mesh is automatically discharged to avoid the accumulation of small stones and damage the mesh.
