Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture, in particular to a liftable sea cucumber culture device. Background Art

[0002] Sea cucumbers are often farmed in breeding boxes located on the seabed. These breeding boxes are mostly made of solid materials with a certain degree of pressure resistance and corrosion resistance to adapt to the seabed environment. They are composed of a frame and a net body. The net body ensures the circulation of seawater and creates a natural habitat for sea cucumbers. The bottom area of ​​the breeding box can also be increased to make it have a larger contact surface with the seabed, disperse pressure, and reduce the risk of tipping.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

When the aquaculture box 1 needs to rise, the sealing mechanism can no longer seal the water inlet hole 7. At this time, seawater will enter the hollow groove 3 from the water inlet hole 7 to push the slide plate 6. At the same time, the first spring will also push the slide plate 6, so that the gas in the hollow groove 3 will enter the elastic block 5 through the air inlet pipe 22 under the push of the slide plate 6, so that the elastic block 5 is inflated. After the elastic block 5 expands to a certain extent, the sealing component will no longer seal the port of the connecting groove 4. At this time, the elastic block 5 will contact the seawater, thereby driving the aquaculture box 1 to rise with the help of buoyancy. The above mechanism can complete the rise and fall of the aquaculture box 1 on the seabed. At the same time, the elastic block 5 can be stored to avoid long-term erosion by seawater and damage, and the sealing of the connecting groove 4 by the sealing component can prevent the elastic block 5 from being difficult to fill with gas due to excessive external water pressure when it expands.

The baffle 12 in the present application can be fixed at the port of the connecting groove 4 by means of the engagement between the block 14 and the slot 15, so that the baffle 12 can seal the port of the connecting groove 4. When the elastic block 5 needs to contact water, the disengagement assembly can be used to disengage the block 14 from the slot 15. At this time, the baffle 12 will slide out of the connecting groove 4, so that the elastic block 5 can contact sea water.

[0025] The inner wall of the connecting groove 4 is provided with symmetrically arranged mounting grooves, and a hollow and elastic sealing frame 19 is fixedly connected in the mounting groove. The sealing frame 19 is arched outward on one side close to the baffle 12 and fits with the baffle 12. When the baffle 12 in the present application seals the port of the connecting groove 4, the arched side of the elastic sealing frame 19 will fit with the baffle 12, thereby improving the sealing effect of the baffle 12 on the connecting groove 4.

[0026] A pair of elastic hollow blocks 20 are fixedly connected to the outer wall of the fixed frame 2, a through groove 21 is provided in the fixed frame 2, a first air inlet hole connected to the through groove 21 is provided on the side wall of the hollow block 20, and a second air inlet hole connected to the through groove 21 is provided on the side of the sealing frame 19 close to the first air inlet hole; after the breeding box 1 in the present application is placed in water, the water pressure will squeeze the hollow block 20, so that the gas in the hollow block 20 enters the sealing frame 19 from the through groove 21, thereby expanding the sealing frame 19, and then the arched side of the sealing frame 19 can better fit with the baffle 12 to further improve the sealing performance.

[0027] The outer side wall of the fixed frame 2 is fixedly connected with a symmetrically arranged connecting block 23, the interior of the connecting block 23 is a hollow structure, and a movable plate 25 is slidably connected inside the connecting block 23. A clamping rod 24 is provided on the side of the movable plate 25 close to the fixed frame 2, and the clamping rod 24 is slidably connected to the side wall of the fixed frame 2, and the clamping rod 24 can pass through the breeding box 1; in the present application, the fixed frame 2 can be clamped on the breeding box 1 by passing the clamping rod 24 through the breeding box 1, and then the breeding box 1 is placed in water, and the clamping rod 24 is moved to the side of the box away from the fixed frame 2, so that the clamping rod 24 is no longer in contact with the breeding box 1, and then the fixed frame 2 can be removed from the breeding box 1.

[0028] The side of the connecting block 23 away from the clamping rod 24 is slidably connected with a connecting rod 26, and the side of the connecting rod 26 close to the fixed frame 2 is fixedly connected to the movable plate 25, and a group of fourth springs are fixedly connected between the side of the movable plate 25 close to the connecting rod 26 and the inner wall of the connecting block 23; when the clamping rod 24 needs to be moved, the movement of the clamping rod 24 can be controlled by the exposed connecting rod 26, and by pulling the connecting rod 26, the movable plate 25 can drive the clamping rod 24 away from the breeding box 1, and after releasing the connecting rod 26, the fourth spring will push the movable plate 25, so that the movable plate 25 drives the clamping rod 24 to pass through the breeding box 1.

[0029] Embodiment 2: Figure 7As shown, compared with Example 1, another implementation of the present invention is: a rectangular groove 27 is opened on the bottom surface of the baffle 12 at the bottom end, and a buffer plate 28 is slidably connected to the inner wall of the rectangular groove 27, and a group of fifth springs are fixedly connected between the top surface of the buffer plate 28 and the inner wall of the rectangular groove 27, and a group of connecting columns 29 are fixedly connected to the bottom surface of the buffer plate 28; when the breeding box 1 in the present application enters the seabed, the connecting columns 29 will contact the seabed, and at this time, the buffer plate 28 will buffer the breeding box 1 under the action of the fifth spring to prevent the breeding box 1 from being damaged.

[0030] Working principle: by placing the breeding box 1 on the sea surface, the breeding box 1 will descend at sea until it reaches the seabed to breed sea cucumbers. When the breeding box 1 needs to rise, the sealing mechanism will no longer seal the water inlet hole 7. At this time, seawater will enter the hollow groove 3 from the water inlet hole 7 to push the slide plate 6. At the same time, the first spring will also push the slide plate 6, so that the gas in the hollow groove 3 will enter the elastic block 5 through the air inlet pipe 22 under the push of the slide plate 6, so that the elastic block 5 is inflated. After the elastic block 5 expands to a certain extent, the sealing component will no longer seal the port of the connecting groove 4. At this time, the spring The elastic block 5 will come into contact with the seawater, thereby driving the aquaculture box 1 to rise with the help of buoyancy. The aquaculture box 1 can be raised and lowered on the seabed by the above mechanism. At the same time, the elastic block 5 can be stored to avoid being damaged by seawater erosion for a long time, and the sealing of the connecting groove 4 by the sealing component can prevent the elastic block 5 from being difficult to be filled with gas due to excessive external water pressure when it expands. In the present application, the sealing plate 9 is sucked by the electromagnet 11 to make the sealing plate 9 slide in the slide groove 8, so that the through hole 10 on the sealing plate 9 can be aligned with the water inlet hole 7, and then seawater can enter the hollow groove 3 from the water inlet hole 7; The baffle 12 in the present application can be fixed at the port of the connecting groove 4 by means of the clamping connection between the clamping block 14 and the clamping groove 15, so that the baffle 12 can seal the port of the connecting groove 4. When the elastic block 5 needs to contact with water, the clamping block 14 can be disengaged from the clamping groove 15 by means of the disengagement component. At this time, the baffle 12 will slide out of the connecting groove 4, so that the elastic block 5 can contact with seawater; in the process of expansion, the hollow block 20 in the present application will push the fixed plate 17, and at this time the fixed plate 17 will drive the magnetic plate 16 to move downward, so that the magnetic plate 16 can attract the clamping block 14 to disengage from the clamping groove 15, and then the elastic block 5 continues to expand and push the baffle 12, so that the baffle 12 is disengaged from the connecting groove 4, so that the hollow block 20 can contact with water, thereby driving the aquaculture box 1 to rise, and when rising, the connecting rope 18 will pull the baffle 12 to rise together; When the baffle 12 in the present application seals the port of the connecting groove 4, the arched side of the elastic sealing frame 19 will fit with the baffle 12, thereby improving the sealing effect of the baffle 12 on the connecting groove 4; after the breeding box 1 in the present application is placed in water, the water pressure will squeeze the hollow block 20, so that the gas in the hollow block 20 enters the sealing frame 19 from the through groove 21, so that the sealing frame 19 expands, and then the arched side of the sealing frame 19 can better fit with the baffle 12, so as to further improve the sealing performance; The present application can clamp the fixed frame 2 on the breeding box 1 by passing the clamping rod 24 through the breeding box 1, and then the breeding box 1 is placed in the water, and the clamping rod 24 is moved to the side of the box away from the fixed frame 2, so that the clamping rod 24 is no longer in contact with the breeding box 1, and then the fixed frame 2 can be removed from the breeding box 1; when the clamping rod 24 needs to be moved, the present application can control the movement of the clamping rod 24 through the exposed connecting rod 26, and by pulling the connecting rod 26, the movable plate 25 can drive the clamping rod 24 away from the breeding box 1. After the connecting rod 26 is released, the fourth spring will push the movable plate 25, so that the movable plate 25 drives the clamping rod 24 to pass through the breeding box 1.
