DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Existing aquatic organism collection and fishing devices will catch all the organisms in the water during the collection process, and then different organisms need to be sorted out manually, resulting in a large time cost problem in subsequent work.

[0022] In view of this, the utility model provides an aquatic life collection and fishing device. Through the cooperation between the first filter net, the second filter net and the third filter net, when the hull moves in the water, it will drive the fishing net at the rear to collect and fish the life. After the aquatic life enters the fishing net, it will pass through the first filter net, the second filter net and the third filter net in sequence. According to the size of the life, it will stay in different areas inside the fishing net. When it goes ashore, the life in each area will be taken out, which solves the problem that the life in the water will be caught together, and then different life will need to be manually sorted out, resulting in a large time cost in subsequent work.

[0023] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0024] Embodiment 1: Figure 1-4 It can be seen that an aquatic life collection and fishing device includes a hull 1, a grading fishing device is installed on one side of the hull 1 through a rope 4, and the grading fishing device includes a ring 5, a fishing net 6, a blocking block 14, a positioning pin shaft 15, a first filter 16, a second filter 17 and a third filter 18. The top of the fishing net 6 is fixed with a ring 5, and the ring 5 is sleeved with a rope 4, so that the hull 1 can pull the fishing net 6 to move forward, and the inside of the fishing net 6 is sequentially installed with the third filter 18, the second filter 17 and the third filter 18 through the positioning pin shaft 15. The organisms entering the fishing net 6 will pass through the third filter 18, the second filter 17 and the first filter 16 in sequence, thus achieving the biological classification treatment. The mesh number of the first filter 16 is greater than the mesh number of the second filter 17, and the mesh number of the second filter 17 is greater than the mesh number of the third filter 18. The tops of the first filter 16, the second filter 17 and the third filter 18 are all attached with a blocking block 14 fixed to the top of the inner wall of the fishing net 6 on one side away from the hull 1.

[0025] In the specific implementation process, it is worth pointing out that the ring 5 is sleeved with a rope 4, so that the hull 1 can pull the fishing net 6 to move forward, and the organisms entering the fishing net 6 will pass through the third filter 18, the second filter 17 and the first filter 16 in sequence. When the hull 1 returns to the shore, the organisms in various areas inside the fishing net 6 can be taken out. When taking away the organisms, the filter nets can be lowered in sequence by rotating the positioning pin 15, which is also convenient for taking away the organisms. The positioning pin 15 can make the filter net realize the effect that the filter net will not move freely without the action of external force;

[0026] Specifically, when using the aquatic life collection and fishing device, when it is necessary to collect aquatic life in a certain area of ​​water, the hull 1 is placed in the water. When the hull 1 moves in the water, the fishing net 6 at the rear catches the life, and the caught life will enter different areas inside the fishing net 6 according to its size, which makes it convenient to classify and process the life after returning to the shore.

[0027] Embodiment 2: By Figure 1-4 It can be seen that a controller 12 is fixedly connected to the top of the hull 1, and the controller 12 contains circuit elements, a signal receiver, a timing signal generator, an interrupt mechanism, etc., and this technology is well known to those skilled in the art and will not be described in detail here. The front and back of the hull 1 are both equipped with lifting propellers 11, which can provide the hull 1 with diving and floating functions;

[0028] In the specific implementation process, it is worth pointing out that after the hull 1 is put into the water, the hull 1 can be made to dive or float in the water by rotating the lifting propeller 11 forward and reversely, and the hull 1 itself has the function of moving forward to collect and catch fish at various locations in the water area;

[0029] Furthermore, the front and back sides of the hull 1 are fixedly connected with a first connecting rod 13, a side of the first connecting rod 13 away from the controller 12 is fixedly connected with an inclined rod 10, the bottoms of the two inclined rods 10 are fixedly connected with support rods 9, and the ends of the two support rods 9 close to the fishing net 6 are fixedly connected by a second connecting rod 8;

[0030] In the specific implementation process, it is worth pointing out that when the hull 1 dives to the bottom of the water, under the action of the inclined rod 10 and the support rod 9, the hull 1 can land on the bottom of the water steadily without capsizing;

[0031] Furthermore, the second connecting rod 8 is fixedly connected to a sleeve 7 on one side close to the fishing net 6, the top of the sleeve 7 is fixedly connected to a telescopic cylinder 2 through a support rod 19, the inner wall of one side of the sleeve 7 is movably connected to an insertion rod 3, the bottom of the telescopic cylinder 2 passes through the sleeve 7 and is inserted into the groove at the top of the insertion rod 3, and the telescopic cylinder 2 fixes the insertion rod 3 and the sleeve 7 together;

[0032] In the specific implementation process, it is worth pointing out that when the hull 1 is fishing on the bottom of the water, if the fishing net 6 gets stuck, the telescopic cylinder 2 is started to pull the bottom of the telescopic cylinder 2 out of the groove at the top of the plug rod 3. At this time, the hull 1 will be separated from the fishing net 6 when moving forward, so that the hull 1 can return to the water surface without causing excessive losses.

[0033] Furthermore, a rope 4 is fixedly connected to the outer wall of the plug rod 3, and the other end of the rope 4 is fixedly connected to the ring 5, and the rope 4 connects the fishing net 6 and the hull 1 together;

[0034] In the specific implementation process, it is worth pointing out that when the hull 1 moves, the fishing net 6 is pulled along by the rope 4 wound around the outer wall of the plug rod 3;

[0035] Specifically, on the basis of the above-mentioned embodiment 1, after the hull 1 is put into the water, the hull 1 can be made to dive or float in the water by the forward and reverse rotation of the lifting propeller 11. The hull 1 itself has the function of moving forward to collect and catch fish at various locations in the water area. When the hull 1 dives to the bottom of the water, under the action of the inclined rod 10 and the support rod 9, the hull 1 can fall steadily to the bottom of the water without capsizing. When the hull 1 is fishing on the bottom of the water, if the fishing net 6 gets stuck, the telescopic cylinder 2 is started to pull the bottom of the telescopic cylinder 2 out of the groove at the top of the insertion rod 3. At this time, the hull 1 will be detached from the fishing net 6 when moving forward, so that the hull 1 can be returned to the water surface without causing excessive losses. When the hull 1 moves, the rope 4 wrapped around the outer wall of the insertion rod 3 is used to pull the fishing net 6 to move forward.
