Description

Technical Field

[0001] This utility model relates to the field of algae cultivation technology, and in particular to an algae seedling cultivation device. Background Technology

[0002] In algae cultivation, parent algae cultivation is a crucial step. This involves transferring the parent algae to a new cultivation tank, where they continue to release gametes before being removed. For example, in the cultivation of *Gracilaria longstemica* (also known as sea grape), the parent algae cultivated during the transition period are transferred to a new cultivation tank with increased light intensity (6000-8000 Lx), a photoperiod of 12 L:12 D, and a water temperature of 27-30℃. The parent algae continue to release gametes, are then removed, and the remaining algae are used for further cultivation in the new tank. Traditional methods of placing parent algae baskets rely on directly placing baskets containing the male and female parent algae in the cultivation tank. However, the lack of an effective positioning and movement mechanism makes it difficult to flexibly arrange the baskets within the limited space of the cultivation tank, resulting in low space utilization and consequently affecting cultivation density and yield. When manually adjusting the position of the parent basket, it is easy for it to collide with other baskets, making it difficult to quickly adjust the position or replace the parent basket in a large-scale breeding environment.

[0022] Example 1

[0023] Please refer to the attached document. Figures 1-3 This application provides an algae cultivation device, including a horizontal bar 1, a parent basket 2, and an operating rod 3. The horizontal bar 1 is installed on a cultivation pond, with a column 4 above it and a track 5 above the column 4. The operating rod 3 is placed on the track 5, and the operating rod 3 has a lever 6 with a first hook 7. The parent basket 2 is connected to a second hook 9 via a pull rope 8. The horizontal bar 1 has several hanging holes 10 for placing the second hook 9. During cultivation, male and female parent plants are placed in the parent basket 2, and the parent basket 2 is hung on the hanging holes 10 via the hooks. Multiple parent baskets 2 can be hung on the horizontal bar 1. Since the parent basket 2 is connected to the second hook 9 by pulling, the horizontal bar 1 is positioned on the water surface of the cultivation pond, and the parent basket 2 is submerged in the cultivation water. The height of the parent basket in the water can be controlled by rotating the pull rope 8 of different lengths. When placing and removing the parent basket 2, place the operating lever 3 on the guide rail and hook the first hook 7 with the second hook 9. Then rotate the lever 6 to the horizontal position, so that the parent basket 2 to be moved is not in a straight line with the other parent baskets 2. The rotation of the lever 6 also makes the height of the parent basket to be moved greater than that of the other parent baskets 2. At this time, the operating lever 3 can be pushed along the guide rail to move the parent basket 2. In this invention, when moving the parent basket 2, the parent basket 2 to be moved is staggered from the other parent baskets 2 in both the horizontal and vertical projection directions by a certain distance, so as to avoid the moving parent basket 2 touching the other parent baskets 2. The position of the parent basket 2 can be moved, added, and changed as needed, making the operation convenient.

[0024] Specifically, the second hook 9 includes an inverted U-shaped portion 11 and an O-shaped portion 12. One end of the inverted U-shaped portion 11 is connected to the pull rope 8, and the other end is hooked into the hook hole 10. The U-shaped portion has the O-shaped portion, and the O-shaped portion 12 is connected to the first hook 7. During operation, the first hook 7 is hooked onto the O-shaped portion, making operation more convenient. The inverted U-shaped portion 11 can be hooked into the hook hole 10, thereby stabilizing the second hook 9 on the crossbar 1.

[0025] Specifically, the side of the crossbar 1 is provided with a chamfer 13. The first hook 7 can slide upward along the chamfer 13, making it convenient for the second hook 9 to be hooked into the hanging hole 10.

[0026] Specifically, the second hook 9 is J-shaped, and a limiting protrusion 14 is provided at the upper end of the second hook 9. After the second hook 9 hooks the first hook 7, it can be lifted up a small distance to put the second hook 9 into the hanging hole 10. When taking out the second hook 9, it can also be lifted up a small distance to facilitate taking the second hook 9 out of the hanging hole 10.

[0027] Specifically, the operating lever 3 has a handle 15 at its middle and end. The handle 15 is perpendicular to the operating lever 3 and parallel to the lever 6. When the operating lever 3 is rotated, the contact area between the operating lever 3 and the track 5 serves as the fulcrum. The handle 15 acts as a power arm, driving the lever 6 and the first hook 7 to rotate, thereby raising and moving the parent basket 2 outward.

[0028] Example 2

[0029] Please refer to the attached document. Figures 1-3 The difference between this embodiment and Embodiment 1 is that the bottom of the crossbar 1 is provided with a mounting base 16, and the bottom of the mounting base 16 is provided with a slot 17 for engaging with the side wall of the cultivation tank. The mounting base 16 is perpendicular to the crossbar 1. Engaging the mounting base 16 with the side wall of the cultivation tank improves the stability of the crossbar 1. The perpendicularity of the mounting base 16 to the crossbar 1 provides good support and stability. The increased support surface of the mounting base 16 allows for better rotation of the operating rod 3.

[0030] Specifically, the parent basket 2 includes a base plate 18 and a baffle 19. Both the base plate 18 and the baffle 19 are provided with several through holes 20. The baffle 19 is located around the base plate 18. The base plate 18 and the baffle form a cavity for placing the parent stock. During seedling cultivation, the parent stock is placed in the cavity to prevent it from falling out of the parent basket 2.

[0031] Specifically, the parent basket 2 is provided with connecting ropes 21 around its perimeter. The upper ends of the connecting ropes 21 are connected to each other, and the connecting ropes 21 are connected to the pull rope 8. The upper ends of the connecting ropes 21 are connected together and then connected to the pull rope 8. The pull rope 8 can prevent the parent basket 2 from tipping over when it is pulled.

[0032] Specifically, the operating lever 3 is cylindrical, and a groove 22 is provided on its side. The cylindrical shape of the operating lever 3 facilitates rotation, and the groove 22 on its side reduces the weight of the operating lever 3, making it easier for operators to use.
