Four-layer net structure bat catcher for large cave

Technical Field

The utility model relates to the technical field of bat capturing devices, in particular to a bat catcher with a four-layer net structure for a large cave.

Background

Bats are a class of animals under the phylum chordata, class mammalia, and are the only species that can actually fly. The smallest is the mixed bat, the weight is only 1.9 g, and the span is 16 cm; some bats can weigh more than 1.3 kg and span up to 1.7 meters. The colors are varied, mostly brown, grey and black. The bat is suitable for flying and living at night, and usually has poor vision and abnormal hearing. 70% of bat species feed primarily on insects and other small arthropods; the other species mainly feed on fruits, nectar and pollen; there are 3 kinds of blood sucking bats feeding on blood. Distributed throughout the earth except for the north and south poles and some ocean islands.

Bats can coexist with a variety of viruses, such as: marburg virus, nipa virus, SARS virus, etc., which are natural virus libraries, and thus the study of bats is critical to epidemiological studies. In addition, the bat has important ecological effects in pest control, plant pollination, biological indicators and the like, and has important research values in health and longevity, bionics, language evolution and the like.

The current common bat capture tools and methods can cause varying degrees of damage and impact to operators, caught bats, and other animals, including their habitat and ecological environment, and are less reliable.

The utility model provides a technical scheme that:

example 1

Referring to fig. 1-2, a four-layer net structure bat catcher for a large cave, comprising: the double-layer cloth bag 1, two triangular brackets 2, two hanging cloths 3, two T-shaped brackets 4 and four vertical nets 5;

the two triangular supports 2 are arranged on the left side and the right side, each triangular support 2 is composed of a foot rest rod 6 and a double-layer cloth bag support 7, holes are formed in the surfaces of the triangular supports 2, support cross rod holes 8 are formed in the middle positions of the triangular supports 2, double-layer cloth bag cross rod holes 9 are formed in the tops of the surfaces of the triangular supports 2, lower rod holes 10 are formed in the positions, above the support cross rod holes 8, of the surfaces of the triangular supports 2 on the left side and the right side, support cross rods 8a are arranged in the double-layer cloth bag cross rod holes 9 on the surfaces of the triangular supports 2 on the left side and the right side, lower rods 10a are arranged in the lower rod holes 10 on the surfaces of the triangular supports 2 on the left side and the right side, the T-shaped supports 4 are fixedly connected to the tops of the triangular supports 2 on the left side and the right side, upper rod holes 11 are formed in the tops of the surfaces of the T-shaped supports 4, upper rods 11 are arranged on the tops of the upper rods 11, positions of the lower rods 10a and the upper rods 11a correspond to each other, vertical nets 5 are arranged between the lower rods 10a and the upper rods 11a, hanging cloth bags 3 are arranged on the double-layer cross rods 9a, and the other ends of the hanging cloth 3 are connected with one ends of the double-layer cloth bags 1 respectively.

Further: the space arrangement of the vertical nets 5 should meet the condition that the bat cannot easily fly inside the vertical nets and can drop into the double-layer cloth bag 1 downwards through the gravity of the bat, the net wires of the vertical nets 5 can adopt common white fishing wires, the net wire density of the vertical nets is adjustable, the space arrangement should be carried out according to the size of the body for capturing the bat, and the space between the net wires should generally meet the condition that the space between the net wires is smaller than the span of the bat; the setting of net twine should be in the state of stretching out and tightening, possess certain elasticity and intensity, the frame height-adjustable of T type frame, generally adjust to the net twine of erecting net 5 be in the state of stretching out and tightening out can, the tripod 2 should adopt the great material of dead weight, make the focus of whole device lie in below and stable, the elasticity of its sack is adjusted to double-deck sack 1 accessible limit rope, generally adjust the bat that drops in the top can smoothly slide into the bag can, erect the space of net 5 in both sides tripod 2 department need be covered with plastic film.

In actual operation, when the device is in use, the bat is not detected as flying out or back into the cavity at night, and the presence of the trap vertical net 5 is thereby directly impacted in both directions and passed through the vertical net. The small bat can pass through one layer of vertical net and cannot pass through the second layer of vertical net; for large bats, one or two layers of vertical nets can be penetrated, and more than two layers of vertical nets cannot be penetrated. When the bat passes through the vertical nets from two different directions and enters the device, the bat cannot continuously spread wings to fly due to limited space between the vertical nets, so that the bat can fall into the double-layer cloth bag 1 arranged below along with self gravity or fall onto the hanging cloth 3 and then fall into the double-layer cloth bag 1. Because the opening of the double-layer cloth bag is narrow, the width of the bag body is limited, and the bat cannot spread wings to fly, so that the bat cannot escape from the device finally.

It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.
