Description

Technical Field

[0001] The utility model relates to the technical field of diatom cultivation, in particular to a diatom cultivation device for aquaculture. Background Art

[0002] Diatoms are rich in proteins, polysaccharides, lipids, and various inorganic salts. They do not contain cellulose and can be easily ingested and digested by aquatic animals. They can be used as the starting bait for aquatic animals such as shrimp seedlings, sea cucumber seedlings, and sea urchin seedlings. Compared with other algae, diatoms have strong photosynthesis, which makes the oxygen solubility of the water body high. They grow fast and can have a strong decomposition and absorption effect on pollutants, toxins, and organic matter in the water, increasing the water purification capacity. They can create a growth environment suitable for aquatic animals, improve survival rates, and increase production. Diatoms are heavy and easy to exist at the bottom of the water, and sea urchin seedlings generally live at the bottom of the water. Sea urchin seedlings often feed on diatoms. Therefore, in the cultivation of sea urchin seedlings, the sufficient addition of diatoms can not only ensure the nutritional needs of sea urchin seedlings, improve the disease resistance and immunity of sea urchins, and improve the survival rate, but also increase their growth rate.

[0003] Since diatoms are tiny, they can only be observed under a microscope. When they are cultured, they need an attachment, on which they grow and reproduce, and then they are harvested by scraping the surface of the attachment. Since diatoms are heavy, especially after death, they tend to sink to the bottom. Therefore, when diatoms are cultured, the bottom must be cleaned in time to avoid a large number of diatoms dying and sinking to the bottom, affecting the water quality. The bottom cleaning operation of existing incubators mostly requires complete drainage and termination of diatom culture, which is relatively complicated. In addition, the growth of diatoms is closely related to light. Ordinary incubators are easily shaded, have low light rates, and grow slowly.

[0004] To this end, we propose a diatom cultivation device for aquaculture. Utility Model Content

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] Example 1

[0035] like Figure 1-2 As shown, a diatom culture device for aquaculture includes a transparent circular culture box 100 and an L-shaped ventilation pipe 200. A collection tank 102 is provided on the transparent bottom plate 101 of the circular culture box 100. A drainage valve 107 connected to one end of the collection tank 102 is installed at the bottom of the transparent bottom plate 101. A plurality of transparent attachment plates 300 are mounted on the vertical portion of the ventilation pipe 200, and a scraper 203 is fixedly connected to one side of the lower end of the ventilation pipe 200. The width of the scraper 203 is greater than the width of the collection tank 102. When the scraper 203 covers the collection tank 102, a sewage discharge channel is formed inside the collection tank 102. During implementation, one end of the ventilation pipe 200 is placed at the inner center of the circular culture box 100, and the diameter of the attachment plate 300 is 3-20 mm smaller than the diameter of the circular culture box 100. During implementation, the size matching can be flexibly set.

[0036] like Figure 1 As shown in the figure, a threaded sleeve 301 is fixedly installed in the middle of the attachment plate 300, a threaded portion 201 is provided on the vertical portion of the vent pipe 200, and the threaded sleeve 301 is threadedly installed on the threaded portion 201. Through the arrangement of the threaded portion 201, the spacing and height of the attachment plate 300 can be flexibly adjusted, which is very convenient.

[0037] like Figure 1As shown in , the threaded portion 201 is provided with an aeration port 202 that does not damage the thread function. Air can be introduced into the circular culture box 100 through the aeration port 202 to increase oxygen or carbon dioxide, thereby promoting the growth of diatoms or ensuring their survival. During implementation, a threaded plug is installed at the mouth of the aeration port 202, which can be blocked or opened as needed, and is easy to use.

[0038] When implementing, Figure 1 As shown in FIG. 3 , an exhaust port 302 is provided at the edge of the attachment plate 300. A plurality of exhaust ports 302 are provided, and the exhaust ports 302 at the edges of the plurality of attachment plates 300 can be arranged in an aligned manner.

[0039] like Figure 1 As shown in the figure, it also includes an air pump 500, the outlet of the air pump 500 is connected to one end of the ventilation pipe 200 through a hose 501, and the hose 501 and the ventilation pipe 200 are detachably connected. Aeration is performed by the air pump 500, and the hose 501 and the ventilation pipe 200 can be detached, so that the horizontal part of the L-shaped ventilation pipe 200 can be used as a push handle for rotation, which is convenient for operation.

[0040] Example 2

[0041] Different from Example 1, the bottom of the circular incubator 100 is provided with legs 104, the lower end of the legs 104 is provided with bottom wheels 105, and the legs 104 are provided with mirrors 106 that reflect light upward. The design of the legs 104 and bottom wheels 105 facilitates the circular incubator 100 to be pushed outdoors for cultivation, and the mirrors 106 can increase the reflection rate of sunlight and improve the growth rate of diatoms.

[0042] Example 3

[0043] Different from the first embodiment, a sleeve 204 is connected to the horizontal part of the vent pipe 200, a limiting rod 400 is slidably inserted in the sleeve 204, and the lower end of the limiting rod 400 is inserted into the exhaust port 302. In this way, when the L-shaped vent pipe 200 is rotated, the attachment plate 300 can be rotated synchronously, so as to adjust the light receiving part.

[0044] Example 4

[0045] Different from Example 1, Figure 3 As shown in the figure, it also includes a vertical rod 600. The outer side of the circular incubator 100 is fixedly connected with a limiting cylinder 103. One side of the vertical rod 600 is fixedly connected with a clamping block 601. When the clamping block 601 is slidably inserted into the limiting cylinder 103, the vertical rod 600 penetrates into the exhaust port 302.

[0046] When the vertical rod 600 is inserted into the exhaust port 302, the ventilation tube 200 is rotated, and under the action of the threaded portion 201, multiple attachment plates 300 can be raised synchronously to facilitate rapid harvesting.

[0047] Example 5

[0048] The difference from Example 1 is that it also includes a feeding tool, such as Figure 4 As shown in the figure, the feeding tool includes a feeding tube 700, one end of which is provided with a material box 702, and a manual valve 701 is installed on the feeding tube 700. Through the feeding tool, materials such as sodium silicate, silicon dioxide and probiotics that are beneficial to the growth of diatoms can be added between each attachment plate 300, and the operation is convenient.

[0049] Example 6

[0050] First, the usage method is different from that of Example 1. After the diatom culture is completed, there is no need to harvest. It can be directly sown on the attachment plate 300 (such as sea urchin seeds) for seedling culture. After a period of culture, underwater sowing is carried out. During the culture process, the production speed of diatoms can meet the needs of the initial sea urchin seedlings. When the seedlings grow to be suitable for underwater sowing, they are transferred to underwater sowing.

[0051] More specifically, different from Example 1, Figure 5 As shown in the figure, a retaining edge 303 is provided at the edge of the attachment plate 300, and the retaining edge 303 can play a shielding role to prevent the aquatic product seedlings (such as sea urchin seedlings) from being too scattered during underwater sowing. For example, sea urchins are gregarious animals and are generally sown in a centralized manner; and a hanging ring 205 is fixedly connected to the upper end of the vent pipe 200. After the vent pipe 200 is directly suspended by the hanging ring 205 through a rope, a crane or a winch, it slowly sinks to the bottom of the water for sowing. After sinking to the bottom of the water, it is retained for a period of time to facilitate the spread of the sea urchin seedlings to the surroundings.

[0052] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive. Although the present application is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to perform equivalent replacement of some of the technical features therein. Any equivalent structure made using the contents of the specification and drawings of this application, directly or indirectly used in other related technical fields, is similarly within the scope of patent protection of this application.
