DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] like Figure 1-Figure 7 As shown, this embodiment proposes an underwater sea cucumber fishing device, including a slide rod 2, the slide rod 2 is fixedly connected to a bottom plate 1, both ends of the slide rod 2 are rotatably connected to a clamping plate 11 for clamping the sea cucumber through a rotating shaft, the slide rod 2 is rotatably connected to the rotating shaft, the clamping plate 11 is fixedly connected to the rotating shaft, and the rotating shaft is connected to the slide rod 2 through a torsion spring.

[0032] The torsion spring is used for resetting the clamping plate 11. In the initial state, under the action of the torsion spring, the clamping plate 11 can be in an open state, which makes it easy for the sea cucumber to move between the two clamping plates 11. When the clamping plate 11 rotates to clamp the sea cucumber, the torsion spring is deformed.

[0033] The top plate 12 is fixedly connected to the upper end of the clamping plate 11, and the bottom plate 1 is arranged below the clamping plate 11. The top plate 12, the clamping plate 11 and the bottom plate 1 are mutually enclosed to form a clamping space for clamping sea cucumbers. The clamping plate 11 can drive the top plate 12 to move. In the initial state, there is a suitable gap between the top plates 12, so as to facilitate the entry of sea cucumbers.

[0034] The slide rod 2 is also slidably connected with a pull plate 13, which is located between the two clamps 11 and can drive the other end of the clamp 11 to move inward to clamp the sea cucumber. The pull plate 13 and the clamp 11 are in contact with each other. When the pull plate 13 moves, it can drive the clamp 11 to move, and the clamp 11 can drive the top plate 12 to move, thereby enclosing the sea cucumber.

[0035] The operation is convenient. When in use, one only needs to pull the pull rope 22, and the pull rope 22 drives the pull plate 13 to move, so as to clamp the sea cucumber. Moreover, the enclosed clamping space can effectively prevent the sea cucumber from escaping. The sea cucumber can be caught without a large clamping force, which effectively reduces the damage to the sea cucumber.

[0036] The top plate 12, the clamping plate 11 and the bottom plate 1 are all provided with water holes. Under the action of the water holes, the water flow will not remain in the clamping space, thereby reducing the weight of the clamping space and facilitating the movement of the entire device.

[0037] The pull plate 13 is connected to the slide rod 2 through the first spring 21. The first spring 21 is sleeved on the pull plate 13. One end of the first spring 21 is connected to the pull plate 13, and the other end of the first spring 21 is connected to the slide rod 2. In the initial state, under the action of the first spring 21, the pull plate 13 is located on the side close to the rotating shaft. At this time, the clamp 11 is in an open state, and the first spring 21 is used for resetting the pull plate 13.

[0038] It also includes a sleeve 3, the slide rod 2 and the sleeve 3 are slidably connected, a plurality of sliding holes are opened on the inner side of the sleeve 3, and both ends of the slide rod 2 are slidably connected with a block 23 that can slide into the sliding hole. When the block 23 slides into the sliding hole, the slide rod 2 and the sleeve 3 can be relatively locked to achieve length limitation.

[0039] The slide bar 2 is slidably connected to an unlocking rod 25 that moves in the vertical direction. The unlocking rod 25 is located between the two blocks 23. The contact surface between the unlocking rod 25 and the block 23 is an inclined surface. When the unlocking rod 25 moves upward, it can drive the blocks 23 on both sides to move at the same time. The unlocking rod 25 can drive the blocks 23 to slide into the sliding hole.

[0040] The block 23 is connected to the slide bar 2 via a second spring 24 , and the unlocking rod 25 is connected to the slide bar 2 via a third spring 26 . The second spring 24 is used for resetting the block 23 , and the third spring 26 is used for resetting the unlocking rod 25 .

[0041] The elastic force of the third spring 26 is greater than the elastic force of the second spring 24. In the initial state, under the action of the third spring 26, the unlocking rod 25 can be driven to rise, and the unlocking rod 25 drives the block 23 to slide into the sliding hole. At this time, the second spring 24 is deformed. When the unlocking rod 25 descends, under the action of the second spring 24, the block 23 can be moved out of the sliding hole.

[0042] The length of the slide rod 2 can be adjusted, and the unlocking rod 25 and the block 23 are arranged to cooperate with each other. Several blocks 23 can be arranged according to actual needs, which can effectively improve the stability effect. The length of the fishing device can be freely adjusted according to actual use requirements.

[0043] The sleeve 3 is rotatably connected to a rope-collecting wheel 43, a pull rope 22 is wound around the rope-collecting wheel 43, and the other end of the pull rope 22 is connected to the pull plate 13. The rope-collecting wheel 43 can drive the pull rope 22 to wind, and the pull rope 22 can drive the pull plate 13 to move.

[0044] The rope taking-up wheel 43 is connected to a spiral spring 45, and the elastic force of the spiral spring 45 is much smaller than the elastic force of the first spring 21. When the slide rod 2 becomes shorter, the spiral spring 45 can drive the rope taking-up wheel 43 to rotate to achieve rope taking-up, so that the pull rope 22 can always be in a taut state, so that the drive of the pull rope 22 to the pull plate 13 will not be affected by the adjustment of the slide rod length 2.

[0045] When the slide rod 2 becomes longer, the pull rope 22 will drive the rope-collecting wheel 43 to rotate, which will further deform the spiral spring 45. Since the elastic force of the spiral spring 45 is much smaller than the first spring 21, the elastic force of the spiral spring 45 will still be smaller than the first spring 21, so it will not pull the pull plate 13 to move, and the state of the clamping plate 11 will not change.

[0046] The sleeve 3 is slidably connected with a pressure rod 44, which is connected to the sleeve 3 through a fourth spring 46. The fourth spring 46 is used for resetting the pressure rod 44. The pressure rod 44 is fixedly connected with a rack 41, and the rope-collecting wheel 43 is coaxially connected with a gear 42, and the rack 41 and the gear 42 are meshed.

[0047] The two ends of the sleeve 3 are fixedly connected with handles 31, and the pressure rod 44 is located between the two handles 31, so as to be convenient for holding. When the pressure rod 44 moves toward the handle 31 on the right side, the pressure rod 44 can drive the rope collecting wheel 43 to rotate through the gear 42, and the rope collecting wheel 43 realizes rope collection. At this time, the pull rope 22 can drive the pull plate 13 to rotate to clamp the sea cucumber. Since the other end of the pull rope 22 is arranged at the pressure rod 44, it is convenient for the staff to operate and hold it.

[0048] In the initial state, under the action of the fourth spring 46, the rack 41 is located on one side of the gear 42 and is not meshed with the gear 42. Therefore, when the length of the slide bar 2 is adjusted to rotate the rope-collecting wheel 43, the rack 41 will not affect the rotation of the rope-collecting wheel 43.

[0049] The specific working process is as follows: pull the unlocking rod 25 downward, and under the action of the second spring 24, the block 23 moves out of the sliding hole. At this time, relative sliding can occur between the sliding rod 2 and the sleeve 3. According to the required length, adjust the sliding rod 2 to a suitable position, and then release the unlocking rod 25. The third spring 26 drives the unlocking rod 25 to reset upward, and the unlocking rod 25 drives the block 23 to move into the sliding hole, causing the second spring 24 to deform.

[0050] By moving the position of the clamping plate 11, the sea cucumber is moved between the clamping plates 11, and by pinching the pressure rod 44, the pressure rod 44 drives the rack 41 to move, the rack 41 drives the gear 42 to rotate, the gear 42 drives the rope collecting wheel 43 to rotate, the rope collecting wheel 43 drives the pull rope 22 to move, the pull rope 22 drives the pull plate 13 to move, the pull plate 13 drives the clamping plate 11 to rotate, and the clamping plate 11 simultaneously drives the top plate 12 to rotate, thereby clamping the sea cucumber. The top plate 12, the clamping plate 11 and the bottom plate 1 are mutually enclosed to form a clamping space for clamping the sea cucumber. The sea cucumber is located in the clamping space, thereby completing the capture of the sea cucumber.

[0051] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
