Background
Lantern fish belongs to small fish, and belongs to the phylum vertebrata, class Osteichthyes, subclasses Radiata, order Langeridae, and family Langeridae. The species of the lantern fishes are many, and about 250 lantern fishes are known globally and belong to 33 genera, including the genera Alopecurus, Iris, Coleus and the like.
The lantern fishes mainly live in deep sea of open sea areas, the distribution areas are wide, the distribution water depth range is wide, and the catching difficulty of the lantern fishes is large. A means of attracting and gradually directing the light into a net over a wide area has been developed to trap the lantern, but no net suitable for this purpose exists in the prior art.

The utility model provides a technical scheme that its technical problem adopted provides a gravity type expansion lantern fish traps netting gear, including toper screen panel, connecting piece, weight piece, bracing piece and haulage rope, screen panel bottom opening, be equipped with a plurality of bracing pieces along the even interval of circumference between the bottom opening of connecting piece and screen panel, the bracing piece outer end is connected with the open end of screen panel, inner and connecting piece rotatable coupling, be equipped with matched with level auto-lock structure between the inner of bracing piece and the connecting piece, the below at the connecting piece is connected to the weight piece, the haulage rope lower extreme is connected with the connecting piece, the upper end is drawn forth from the screen panel top.
The inner that the connecting piece corresponds each bracing piece along circumference is equipped with the notch respectively, be equipped with spacing shoulder in the notch, the bracing piece is inserted through pivot structure and is installed in the notch, the bracing piece rotates when the level position the inner of bracing piece and spacing shoulder level and supports to press and form the auto-lock.
The lower extreme of connecting piece is equipped with the engaging lug, the piece that weighs down is connected with the engaging lug through connecting the rope.
The top end of the connecting piece is provided with a connecting lug, and the lower end of the traction rope is connected with the connecting lug.
The top of screen panel is equipped with the link, the link is equipped with the bullport along the center pin of screen panel, the haulage rope is worn out from the bullport.
Be equipped with on the link and be used for the male spacing hole of pump suction pipe, the pump suction pipe is fixed pump suction pipe through connector and spacing jogged joint.
When the mesh enclosure is in an expanded state, the connecting piece is located at the central axis position of the mesh enclosure.
Advantageous effects
The utility model discloses in, when the screen panel was put in the water, under the action of gravity of weighing down the piece, can stimulate the connecting piece downwards for the bracing piece relative connecting piece takes place to rotate and struts the bottom net gape of screen panel automatically, realizes the automatic expansion of screen panel. When the supporting rod reaches the horizontal position, self-locking is formed between the supporting rod and the connecting piece, and the opening state of the mesh opening of the mesh enclosure can be effectively kept. The connecting piece is pulled upwards through the traction rope, the supporting rod and the net cover can be driven to be folded, the net can be rapidly folded, and the operation is simple and convenient.

Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
As shown in fig. 1, the gravity type expanded lantern fish trapping net comprises a net cover 1, a connecting piece 2, a falling block 3, a supporting rod 4 and a traction rope 5.
The net cover 1 is a conical structure with an opening at the bottom, the top of the net cover 1 is provided with a connecting frame 7, and the netting of the net cover 1 is connected with the connecting frame 7. Be equipped with spacing hole 9 on the link 7, when traping the lantern fish, the catch through on the fishing boat catch thing pump suction transfer device to the catch thing of trapping pump suction transfer, inside the catch thing pump suction transfer device's pump suction pipe inserted screen panel 1 through spacing hole 9 to be connected with spacing hole 9 through the outside screwed joint of pump suction pipe, thereby fix the pump suction pipe.
Six support rods 4 are uniformly arranged between the connecting piece 2 and the bottom opening of the mesh enclosure 1 at intervals along the circumferential direction, the outer ends of the support rods 4 are connected with the opening end of the mesh enclosure 1, the inner ends of the support rods 4 are rotatably connected with the connecting piece 2, and a matched horizontal position self-locking structure is arranged between the inner ends of the support rods 4 and the connecting piece 2. Specifically, as shown in fig. 2, the connecting member 2 is provided with notches 2-1 corresponding to the inner ends of the support rods 4 along the circumferential direction, the notches 2-1 are provided with limiting shoulders 2-2, the support rods 4 are inserted into the notches 2-1 through a rotating shaft structure, and when the support rods 4 rotate to the horizontal position, the inner ends of the support rods 4 are horizontally pressed against the limiting shoulders 2-2 to form self-locking. When the net cover 1 is in an expanded state, the connecting piece 2 is positioned at the central axis position of the net cover 1.
The lower extreme of connecting piece 2 is equipped with the engaging lug, weighs down piece 3 and is connected with the engaging lug through connecting rope 6. The top end of the connecting piece 2 is provided with a connecting lug, and the lower end of the traction rope 5 is connected with the connecting lug. The connecting frame 7 is provided with a guide hole 8 along the central axis of the mesh enclosure 1, the traction rope 5 penetrates through the guide hole 8, and the upper end of the traction rope is led out from the top of the mesh enclosure 1.
This net is traped to gravity type expansion lantern fish when using: insert the pump suction pipe inside screen panel 1 earlier and fix, put in the sea water with screen panel 1 again, under the action of gravity of weighing down piece 3, can stimulate connecting piece 2 downwards for bracing piece 4 takes place to rotate relative connecting piece 2 and struts the bottom net gape of screen panel 1 automatically, realizes the automatic expansion of screen panel 1. When the supporting rod 4 reaches the horizontal position, self-locking is formed between the supporting rod 4 and the connecting piece 1, and the opening state of the mesh opening of the mesh enclosure 1 can be effectively kept. When the catch is induced to enter the inside of the net cover 1, the catch is transferred by a catch pump suction transfer device. After fishing, the connecting piece 2 is pulled upwards through the traction rope 5, the supporting rod 4 and the net cover 1 can be driven to be folded, quick net folding is achieved, and operation is simple and convenient.
