[0029] The utility model will be described in detail in combination with the drawings.

[0030] Please refer to Figures 1-4 , the embodiment provides a liftable canvas pool for seawater crab small water physical seedling, which is applied to seawater crab seedling small water body breeding experiment. The canvas pool includes a canvas pool body 1, a frame for supporting the pool opening of the canvas pool body 1, six groups of vertical support steel pipes 4 for supporting the frame, auxiliary lifting pipes 7 sleeved outside the corresponding vertical support steel pipes 4, and PVC hard pipes 8.

[0031] The canvas pool body 1 is made of canvas material, which can be flexibly folded and unfolded. In this embodiment, the unfolded canvas pool body 1 is a rectangular cuboid with a length of 2 m, a width of 1 m and a height of 1 m. The frame includes two groups of long side frame steel pipes 2 and two groups of short side frame steel pipes 3. The two groups of long side frame steel pipes 2 are arranged in parallel and transversely, and the two groups of short side frame steel pipes 3 are arranged between the two groups of long side frame steel pipes 2 and are perpendicular to the long side frame steel pipes 2. The canvas pool body 1 is provided with a sleeve cavity for accommodating the frame, and the ends of the long side frame steel pipes 2 and the short side frame steel pipes 3 extend out of the canvas pool body 1 and do not contact each other.

[0032] The four groups of vertical support steel pipes 4 are evenly arranged at the positions around the canvas pool body 1, and the four corner locking buckles 5 are arranged between the vertical support steel pipes 4 and the frame. The remaining two groups of vertical support steel pipes 4 are arranged at the middle positions of the two groups of long side frame steel pipes 2, and the side locking buckles 6 are arranged between the vertical support steel pipes 4 and the long side frame steel pipes 2. The ends of the adjacent long side frame steel pipes 2 and short side frame steel pipes 3 close to each other are inserted into the corresponding four corner locking buckles 5, and the side locking buckles 6 are arranged at the middle positions of the corresponding long side frame steel pipes 2. The vertical support steel pipes 4 are provided with openings at the top, and the four corner locking buckles 5 are inserted into the corresponding vertical support steel pipes 4 through the openings, and the side locking buckles 6 are inserted into the corresponding vertical support steel pipes 4 through the openings.

[0033] The four corner locking buckles 5 are used to connect the long side frame steel pipes 2, the short side frame steel pipes 3 and the corresponding vertical support steel pipes 4, and are reinforced by screws. The side locking buckles 6 are used to connect the long side frame steel pipes 2 and the corresponding vertical support steel pipes 4, and are also reinforced by screws, so as to form a support frame to support the unfolded canvas pool body 1. The four corner locking buckles 5 used in this embodiment have a structure in which two long 6 cm galvanized steel pipes are vertically combined in the upper half, and a shield shape with a length of 3.5 cm and a width of 0.6 cm in the lower half. The side locking buckles 6 used in this embodiment have an upper half of a galvanized steel pipe with a length of 5 cm and a diameter of 2.8 cm, and a lower half of a shield shape.

[0034] The auxiliary lifting pipe 7 is provided with nine insertion holes on each of the two corresponding side walls, and the nine insertion holes on the same side are arranged in parallel in the vertical direction. The vertical support steel pipe 4 of the embodiment is provided with screw holes of the same specification as the insertion holes at positions 5 cm away from the bottom pipe opening on the two corresponding side walls, and the auxiliary lifting pipe 7 and the corresponding vertical support steel pipe 4 are screwed with a lifting ring bolt through the insertion holes and the screw holes. When the lifting ring bolt is screwed into different positions of the insertion holes, the height of the vertical support steel pipe 4 from the ground changes, thereby achieving the effect of adjusting the canvas pool body 1. The auxiliary lifting pipe 7 of the embodiment uses a hollow steel pipe. Taking the ninth insertion hole from the bottom as an example, the distance between the two adjacent insertion holes is 5 cm. In actual use, the number of screw holes is increased according to the actual load of the canvas pool body 1. In summary, the screw holes and the insertion holes should be aligned to screw in the lifting ring bolt for reinforcement, which will not be described here.

[0035] The canvas pool body 1 is lifted and lowered under the cooperation of the vertical support steel pipe 4 and the corresponding auxiliary lifting pipe 7. When the three groups of vertical support steel pipes 4 on the same side are respectively raised to 60 cm, 35 cm and 10 cm from the ground, the bottom of the canvas pool body 1 forms a 14° slope. In this embodiment, the three groups of vertical support steel pipes 4 on the same side are raised to 60 cm, 35 cm and 10 cm by operating the auxiliary lifting pipe 7 to form a slope of about 14°. At this time, the residual water and crab larvae in the bottom of the canvas pool body 1 can be smoothly drained. Based on the foregoing arrangement, the water and crab larvae in the canvas pool can be completely drained, overcoming the problem that the drainage outlet of the traditional canvas pool is designed on the side of the bottom, and during the breeding process, the water with a height of 3-5 cm remains when the crab larvae are drained. In addition, when cleaning the dirt on the bottom of the canvas pool body 1, the slope adjustment structure is used to form a slope on the bottom of the canvas pool body 1 to drain the dirt, which facilitates the cleaning and maintenance of the canvas pool.

[0036] The canvas pool of the embodiment can determine the inclination angle according to the terrain. For example, the three groups of vertical support steel pipes 4 on the same side are raised to 60 cm, 35 cm and 10 cm by operating the auxiliary lifting pipe 7 to form a slope of about 14° to drain the crab larvae. Compared with the traditional water pump flushing type crab larvae collection method used in the breeding of the flat-bottomed canvas pool, the method can effectively reduce the damage to the crab larvae and improve the collection efficiency of the crab larvae.

[0037] The canvas pool body 1 is provided with a drain opening at a corresponding side position, and a ball valve is externally connected to the drain opening. The PVC hard pipe 8 is located at a corresponding side position of the drain opening. The bottom end of the PVC hard pipe 8 is fixed to the canvas pool body 1, and the top end is connected to the short side frame steel pipe 3 through the fixing buckle 9. In this embodiment, the canvas is fixed when the PVC hard pipe 8 is raised in the canvas pool body 1. In this embodiment, when the ball valve is opened, most of the crab seedlings contained in the canvas pool body 1 flow out to the seedling collector along the drain opening controlled by the ball valve, and the water is filtered out by the seedling collector, and the crab seedlings are collected in the seedling collector. When the water surface is lowered below the drain opening, the auxiliary lifting pipe 7 is operated to make the canvas pool body 1 as a whole in an inclined state, so as to completely drain the water and crab seedlings in the bottom of the canvas pool body 1. The crab seedlings transferred from the canvas are received by the seedling collector. The seedling collector used in this embodiment is a framework composed of eight PVC pipes with a length of 40 cm and four PVC pipes with a height of 10 cm, and the framework is surrounded by a 50-mesh filter screen on four sides and the bottom.

[0038] The canvas pool of this embodiment is an assembled body, which can be disassembled and folded, reduces the occupied space, is convenient to carry and use, can be flexibly selected in the installation location of the device, and improves the use efficiency of the seedling field.

[0039] The use process of the canvas pool in this embodiment is as follows:

[0040] When the ball valve is opened, most of the crab seedlings are discharged through the drain opening. When the water surface is lowered below the drain opening, the ball valve is closed, and then the auxiliary lifting pipe 7 is operated to adjust the long side and the vertical support steel pipe 4 on the opposite side to appropriate heights, so that the canvas pool body 1 forms a certain slope. For example, the long side and the vertical support steel pipe 4 on the opposite side are raised to 60 cm, 35 cm and 10 cm, respectively. At this time, the canvas pool body 1 forms an inclined slope of about 14°. Then, the ball valve is opened to completely drain the water and crab seedlings in the canvas pool.

[0041] In summary, compared with the traditional seawater crab seedling raising measures, the canvas pool of this embodiment has the following advantages: simple structure, small occupied area, low cost, convenient seedling raising, easy daily management, and excellent application prospect in the detection of physical and chemical factors during crab seedling raising and small-scale family construction.

[0042] The names of the various components involved are based on their functions described in the specification as the standard for naming, and are not limited by the specific terms used in the utility model. Those skilled in the art can also use other terms to describe the components of the utility model.
