[0026] In this utility model, such as Figures 1 to 3As shown, a marine ranching device for catching red whelks is provided, including a hollowed-out catching barrel 1. The catching barrel 1 has a whelk inlet hole 2, and the wall of the whelk inlet hole 2 is configured as a funnel shape that gradually narrows from the outside to the inside. The catching barrel 1 is configured as a long barrel, and the whelk inlet hole 2 is located on the side of the catching barrel 1. The catching barrel 1 has a whelk outlet 3 on its side and a door plate 4 that can be opened and closed and installed on the whelk outlet 3. The whelk outlet 3 has a length greater than or equal to 30 cm and a width greater than or equal to 20 cm.
[0027] When using the fishing device of this utility model, the entire fishing bucket 1 is placed in the marine ranch. By placing bait inside the fishing bucket 1, the red whelks can be attracted and enter the fishing bucket 1 through the inlet hole 2. When it is necessary to remove the captured red whelks, the door panel 4 can be removed, and the red whelks inside the fishing bucket 1 can be poured out directly. If some red whelks are attached to the wall of the fishing bucket 1, they can be removed by tapping the wall of the fishing bucket 1 or by inserting a stick through the outlet hole 3.
[0028] The fishing device of this invention adopts a barrel-shaped structure, which is less prone to damage from hooks compared to fishing net-based trapping devices when placed in marine ranches, thus improving its stability. Furthermore, by designing the trapping barrel 1 as an elongated barrel shape, and providing a snail outlet 3 on the side of the trapping barrel 1 that meets the required size (in the embodiment shown, the snail outlet is rectangular), it is easy to pour out the snails from the trapping barrel 1 when it is necessary to remove them. A stick can also be used to assist in cleaning, making it easier to clean. The invention also allows the snail inlet hole to be located at one end of the trapping barrel 1, as shown in the figure, thereby reducing the likelihood of snails entering the trapping barrel 1 moving to the snail inlet hole.
[0029] In a preferred embodiment, more specifically regarding the structure of this utility model, the door panel 4 is connected to the capture bucket 1 via a connecting rope 5.
[0030] In a preferred embodiment, more specifically regarding the structure of this utility model, the capturing barrel 1 includes at least four sides, and the screw outlet 3 and the screw inlet 2 are disposed on two adjacent sides of the capturing barrel 1.
[0031] In the embodiment shown in the figure, the capture bucket 1 is a square bucket-shaped structure with chamfered edges. The screw outlet 3 and the screw hole are located on two adjacent sides of the capture bucket 1, which makes it convenient to clean the inner edge of the screw hole 2 through the screw outlet 3 when cleaning the inside of the capture bucket 1 by opening the door panel 4.
[0032] In a preferred embodiment, specifically regarding the structure of this utility model, the side of the capture bucket 1 is provided with a plurality of water-permeable holes 11, the diameter of which is selected from 0.5 cm to 1.5 cm. As shown in the figure, the water-permeable holes 11 achieve the hollow design of the capture bucket 1. By limiting the diameter of the water-permeable holes 11, the flow of seawater in the capture bucket 1 can be maintained, and the red snails inside can be prevented from escaping through the water-permeable holes 11.
[0033] In a preferred embodiment, more specifically regarding the structure of this utility model, the capturing barrel 1 has a structural hole 6 on the side where the screw inlet 2 is located, the edge of the door panel 4 away from the screw inlet 2 is connected to the edge of the screw outlet 3 by a connecting rope 5, and the edge of the door panel 4 facing the screw inlet 2 is connected to the structural hole 6 by a connecting rope 5.
[0034] As shown in the figure, the edge of the door panel 4 away from the structural hole 6 can be connected by a connecting rope 5 (the shorter connecting rope 5), so that the connecting rope 5 on this side of the door panel 4 is permanently fixed, and the door panel 4 is in a state of approximately one-sided hinge. By fixing the connecting rope 5 (the longer connecting rope 5) to the structural hole 6, the connecting rope 5 can be easily installed and removed on one side of the structural hole 6, so as to facilitate the adjustment of the installation tightness of the door panel 4 and the opening operation of the connecting rope 5.
[0035] In a preferred embodiment, more specifically regarding the structure of this utility model, the fishing device further includes a fixing stake 7 installed in the structural hole 6, the fixing stake 7 being able to fix the connecting rope 5.
[0036] As shown in the figure, the fixed pile is fixed at the position of the structural hole, and the connecting rope 5 is tied to the fixed pile 7 to facilitate the operation of the connecting rope 5.
[0037] In a preferred embodiment, the fixing pile 7 can also serve as a fixing structure for the float.
[0038] In an alternative embodiment, the connecting rope can also be directly attached to the structural hole.
[0039] In a preferred embodiment, specifically regarding the structure of this utility model, the door panel 4 is provided with a positioning ring rib 8 capable of being inserted into the screw outlet 3. This allows the positioning ring rib to limit the movement of the door panel 4 at the edge of the screw outlet, thereby improving the stability of the door panel 4 during installation and also enhancing the sealing effect of the door panel 4 on the screw outlet 3.
[0040] In a preferred embodiment, specifically regarding the structure of this invention, the capturing barrel 1 is detachably fitted with a screw inlet cylinder 9 at the screw inlet hole 2. The cylinder wall of the screw inlet cylinder 9 gradually tapers from the outside to the inside, forming the screw inlet hole. As shown in the figure, this allows for separate processing of the screw inlet cylinder 9 and the capturing barrel 1, facilitating the processing of the gradient structure of the screw inlet hole 2. It also makes it easy to remove the screw inlet cylinder 9 for cleaning, preventing blockage of the screw inlet hole 2.
[0041] In a preferred embodiment, more specifically, regarding the structure of this utility model, the screw inlet 9 and the capture barrel 1 are connected by a threaded connection.
[0042] In a preferred embodiment, more specifically regarding the structure of this utility model, one end of the capturing bucket 1 is provided with a handle 10.
