The bottom surface of the open type base is in a shape like a Chinese character 'pin', three ground iron inserting drill rods are arranged, a U-shaped fixing structure is fixed on the upper surface of the open type base, a net rod is inserted into the U-shaped fixing structure, an elliptical hole is formed in the center of a metal plate, two circular holes are respectively formed in the upper end and the lower end of the metal plate, a punching bolt is inserted into the elliptical hole and penetrates through the net rod, two upper fixing bolts penetrate through the circular holes in the upper end of the metal plate to prop against the outer side of the net rod, and two lower fixing bolts penetrate through the circular holes in the lower end of the metal plate to prop against the inner side of the net rod; the upper end part of the net rod is provided with a fixing hole, the bottom of the external wrapping type folding pointed-end bracket is inserted into the upper end of the net rod, and the bolt penetrates through the fixing hole and the bottom of the external wrapping type folding pointed-end bracket. The utility model can flatly place the net rod to the horizontal state, and can quickly convert the vertical net into the flat net mode so as to play the function of preventing birds from entering the grassland.

Description

Airport is with setting up quick conversion equipment of flat net

Technical Field

The utility model relates to a vertical and horizontal net quick conversion device for an airport.

Background

In order to prevent birds from moving in an airport and reduce the bird attack risk, a certain number of fog nets are laid in an airport flight area and are divided from the aspect of net capture function, the laying mode is mainly divided into a vertical net and a flat net, but the arrangement mode is limited by the trouble of laying the flat net, the arrangement mode of the flat net in the airport is less, but the flat net is an important means for preventing the birds from foraging and inhabiting in the airport grassland, and the night-voyage bird attack probability is more favorably reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a quick conversion device of a vertical net and a flat net for an airport, which achieves the effect of dual purposes of one net, fully improves the use efficiency of a bird net and saves the resource cost.

Aiming at the practical requirement that a flat net needs to be laid in an airport, the utility model provides a vertical and flat net rapid conversion device for the airport, which consists of an open base 1, a perforated bolt 2, an upper fixing bolt 3, a fog net 4, a net rod 5 and an outer wrapping type folding ground-inserting support 8;

the bottom of the open base 1 is in a shape like a Chinese character 'pin', three ground iron inserting drill rods are arranged, a U-shaped fixing structure is fixed on the upper surface of the open base 1, the U-shaped fixing structure is composed of a connecting plate and two vertical and parallel metal plates, a net rod 5 is inserted into the U-shaped fixing structure, an elliptical hole 6 is arranged in the center of each metal plate, two circular holes 7 are respectively arranged at the upper end and the lower end of each metal plate, a perforating bolt 2 is inserted into the elliptical hole 6 and penetrates through the net rod 5, two upper fixing bolts 3 penetrate through the circular holes at the upper end of each metal plate to prop against the outer side of the net rod 5, and two lower fixing bolts penetrate through the circular holes at the lower end of each metal plate to prop against the inner side of the net rod 5; the upper end part of the net rod is provided with a fixing hole, the bottom of the outer wrapping type folding ground inserting support 8 is inserted into the upper end of the net rod, and a bolt penetrates through the fixing hole and the bottom of the outer wrapping type folding ground inserting support 8.

The utility model has the following beneficial effects:

the utility model pulls out the bolts at the two sides of the upper end and the lower end of the metal plate, lifts the net rod a little under the support of the bolts in the elliptical holes, so that the net rod can be horizontally placed to the horizontal state, simultaneously pulls the outer wrapping type folding bracket at the end part of the net rod to be in the vertical state, and inserts the tip into the ground, so that the vertical net can be quickly converted into the flat net mode, and the function of preventing birds from entering the grassland of the net body is exerted.

When the flat net needs to be changed into a vertical net, the inserted support frame at the end part of the net rod is pulled out and collected, the inserted support frame is erected into an upright state by taking the bolt at the base part of the net rod as an axis, and four bolts are inserted into the upper side and the lower side of the base metal plate to fix the net rod, namely, a vertical net mode is formed, so that the function of a net body for blocking birds from flying over a runway is achieved.

Drawings

FIG. 1 is a schematic side view of the present invention;

FIG. 2 is a schematic diagram of a base metal plate structure according to the present invention;

FIG. 3 is a schematic structural view of the "externally wrapped folding insert-ground support" of the present invention.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1-3, a fast vertical and horizontal net switching device for an airport is composed of an open base 1, a perforated bolt 2, an upper fixing bolt 3, a fog net 4, a net rod 5 and an outer-wrapping type folding ground-inserting support 8;

When the device is used, the perforated bolt 2 and the upper fixing bolt 3 of the open base 1 are all inserted, and after the net rods are fixed, the fog net 4 is tied on the two net rods 5, so that a vertical net mode can be formed.

The upper fixing bolt 3 in the metal plate of the open type base 1 is pulled out, the net rod 5 is placed to be in a horizontal state by taking the perforated bolt 2 in the elliptical hole as an axis, the outer wrapping type inserting support 8 at the end part of the net rod 5 is pulled to be in a vertical state, and a flat net mode can be formed after the pointed support is inserted into the ground.
