[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] Please also read Figures 1 to 9Now, a seaweed cultivation device provided by the present invention is described. The seaweed cultivation equipment comprises a culture tank 1, a circulation pipeline 2, a base 3, a temperature control device and a monitoring device; the culture tank 1 comprises a culture chamber 11, a monitoring chamber 12, a filter chamber 13 and a circulation chamber 14; the monitoring chamber 12 is connected to the culture chamber 11 near the bottom; one side of the filter chamber 13 is connected to the monitoring chamber 12, and the other side of the filter chamber 13 is connected to the circulation chamber 14; one end of the circulation pipeline 2 is located in the circulation chamber 14, and the other end is located in the culture chamber 11; wherein the circulation pipeline 2 is provided with a water pump; the base 3 is arranged at the bottom of the culture chamber 11; the temperature control device is arranged in the culture tank 1, and is used to control the temperature of the seawater in the culture tank 1; the monitoring device is arranged in the monitoring chamber 12, and is used to monitor the temperature, salinity, dissolved oxygen content and pH value of the seawater; wherein the base 3 is detachably provided with an enclosure 4, the enclosure 4 is sealed with the base 3, and the height of the enclosure 4 is higher than the liquid level in the culture chamber 11; a coercion cavity is formed between the enclosure 4 and the base 3; when the enclosure 4 is connected to the base 3, the monitoring device is arranged in the coercion cavity. The position where the circulation pipe 2 is connected to the culture chamber 11 is lower than the height of the enclosure 4 to prevent the seawater in the culture chamber 11 from entering the coercion chamber.

[0041] The present invention provides a cultivation device for seaweed. Compared with the prior art, the roots of the seaweed are placed on a base 3, and the root position of the seaweed can be fixed by gravel; the seawater in the culture chamber 11 can be circulated by starting the water pump, that is, the seawater in the culture chamber 11 first enters the monitoring chamber 12, then enters the filter chamber 13, and finally enters the circulation chamber 14. The seawater in the circulation chamber 14 flows back to the culture chamber 11 under the action of the water pump, so that the seawater in the culture chamber 11 circulates; the above-mentioned arrangement facilitates the growth of seaweed in the culture tank 1; during the growth of seaweed, a monitoring device is arranged in the monitoring chamber 12, so that the temperature, salinity, dissolved oxygen content and and pH value, to complete the all-day monitoring of multiple indicators; when it is necessary to monitor the growth of seaweed under the stress of herbicides, petroleum, etc., the enclosure 4 is connected to the base 3, and the seawater inside the enclosure 4 is disconnected from the seawater outside the enclosure 4. At this time, the role of the seawater circulation in the culture tank 1 is to control the seawater temperature in the culture tank 1; stress materials are placed in the seawater inside the enclosure 4. At this time, the temperature, salinity, dissolved oxygen content and pH value of the seawater in the stress chamber can be monitored by the monitoring device; through the above-mentioned settings, the stress materials will not be filtered out by the filter chamber 13, and the experimenters can record the experiments according to the growth of seaweed, which can well reflect the influence of the stress materials on the growth of seaweed.

[0042] It should be noted that the stress materials include herbicides, petroleum materials, microplastics and heavy metals, etc. Since the stress materials are placed in the stress chamber and are not connected to the culture chamber 11, the stress materials in the stress chamber will not enter the culture chamber 11, nor will they be filtered out by the filter chamber 13; through the above arrangement, on the one hand, the stress materials can be prevented from being filtered out; on the other hand, after the experiment is over, it is convenient to separate the stress materials from the culture cylinder 1, that is, the base 3 and the enclosure 4 are lifted out of the culture cylinder 1, so that the stress materials can be separated from the culture cylinder 1.

[0043] Through the above-mentioned setting of the present application, after the experiment is over, the cleaning difficulty of the culture cylinder 1 can be reduced, and only the enclosure 4 and the base 3 need to be cleaned; since the enclosure 4 and the base 3 can be separated, the cleaning difficulty can be reduced. If the stress material is directly placed in the culture chamber 11, it is not convenient to clean the cylinder wall of the culture cylinder 1 after the experiment is over; after the cylinder wall of the culture cylinder 1 is flushed, the water in the culture cylinder 1 is not easy to discharge; therefore, the present application can reduce the cleaning difficulty of the culture cylinder 1 through the setting of the enclosure 4.

[0044] Exemplarily, the temperature control device includes a heating wire, which can heat the seawater in the culture tank 1 when it is powered on, and stop heating when the seawater temperature reaches a preset temperature; the heating method using the heating wire is a prior art and will not be described in detail here. Filter consumables are placed in the filter chamber 13.

[0045] Exemplarily, the monitoring device includes a thermometer, a salinity meter, a dissolved oxygen sensor, and a pH sensor; when measuring the pH of the seawater in the culture tank 1, it can also be detected by a test paper.

[0046] In some embodiments, Figures 1 to 9 As shown, two partitions 15 are arranged between the monitoring chamber 12 and the filter chamber 13, and two partitions 15 are also arranged between the filter chamber 13 and the circulation chamber 14. The arrangement form of the two partitions 15 at the position of the monitoring chamber 12 is exactly the same as the arrangement form of the two partitions 15 at the position of the circulation chamber 14. Here, the two partitions 15 at the position of the monitoring chamber 12 are taken as an example for explanation.

[0047] A transverse plate 16 is fixedly arranged in the culture cylinder 1. The transverse plate 16 is located near one side of the culture cylinder 1. The transverse plate 16 divides the culture cylinder 1 into two parts, wherein the larger part is the culture chamber 11 and the smaller part is the processing chamber. The monitoring chamber 12, the filtering chamber 13 and the circulation chamber 14 are all located in the processing chamber. Two partitions 15 span the processing chamber and are fixed in the culture cylinder 1; the top of one partition 15 is in the same plane as the top of the culture cylinder 1, and the bottom of the other partition 15 is fixed to the bottom of the culture cylinder 1; there is a gap between the two partitions 15, which allows seawater to pass through; through the above arrangement, the processing chamber can be divided into the monitoring chamber 12, the filtering chamber 13 and the circulation chamber 14.

[0048] In some embodiments, Figures 1 to 9 As shown, the bottom end of the enclosure 4 is plugged into the base 3 , and the outer peripheral wall of the enclosure 4 is in contact with the inner peripheral wall of the base 3 ; a connecting structure 5 is provided between the enclosure 4 and the base 3 .

[0049] It should be noted that the enclosure 4 and the base 3 are plugged and matched, and the enclosure 4 and the base 3 are sealed and matched, which can ensure that the seawater in the enclosure 4 is separated from the seawater outside the enclosure 4; when the stress material is put into the seawater in the enclosure 4, it can reduce the entry of the stress material into the culture chamber 11. By providing a connecting structure 5 between the enclosure 4 and the base 3, the connection between the enclosure 4 and the base 3 can be strengthened, and the separation of the enclosure 4 and the base 3 can be reduced.

[0050] In some embodiments, Figures 1 to 9 As shown, the connection structure 5 includes a connection frame 51 and a plurality of plug-in boards 52; the connection frame 51 is connected to the outer peripheral wall of the enclosure 4; when the enclosure 4 is plugged into place, the bottom of the connection frame 51 contacts the top of the base 3; a plurality of slots 53 are provided on the connection frame 51 along its circumference; a plurality of plug-in boards 52 correspond to the slots 53 one by one; the plug-in boards 52 are plugged into and matched with the slots 53, and the plug-in boards 52 are elastic; wherein, the top of the plug-in board 52 has a snap-in portion 54, the top of the snap-in portion 54 is a guide slope 541, and the bottom of the snap-in portion 54 is a plane; when the plug-in board 52 and the connection frame 51 are plugged into place, the bottom of the snap-in portion 54 contacts the top of the connection frame 51 to limit the connection frame 51 in the height direction.

[0051] Exemplarily, the guide slope 541 on the clamping portion 54 faces outward, where outward refers to the direction away from the outer wall of the enclosure 4; when the enclosure 4 is separated from the base 3, experiments can be carried out on the growth of seaweed under normal conditions; when the enclosure 4 and the base 3 are plugged in, stress materials can be placed in the enclosure 4 to study the effects of the stress materials on the growth of seaweed.

[0052] During the plug-in process of the enclosure 4 and the base 3, the guiding inclined surface 541 on the clamping part 54 first contacts the bottom edge of the slot 53; as the enclosure 4 is inserted into the base 3, the guiding inclined surface 541 on the clamping part 54 moves from the small end to the large end, and the plug-in board 52 produces elastic deformation toward the outer wall of the enclosure 4; when the enclosure 4 is plugged in place, the clamping part 54 is located at the top of the connection frame 51, at this time the plug-in board 52 is reset, and the bottom of the clamping part 54 contacts the top of the connection frame 51 to limit the position of the connection frame 51 in the height direction. Through the above arrangement, the connection between the enclosure 4 and the base 3 can be strengthened.

[0053] In some embodiments, Figures 1 to 9 As shown, the outer peripheral wall of the base 3 has connecting protrusions 6 corresponding to the plug-in boards 52 one by one, and the connecting protrusions 6 have threaded holes facing the plug-in boards 52; the connecting protrusions 6 are threadedly engaged with connecting bolts 7, and the connecting bolts 7 are used to push the plug-in boards 52 so that the clamping portion 54 is separated from the top of the connecting frame 51; wherein, the outer peripheral wall of the connecting frame 51 has a slide groove 511 connected to the slot 53, and the slide groove 511 is connected to the bottom of the connecting frame 51; the connecting bolts 7 can be inserted into the slide groove 511, and the connecting bolts 7 can be slidably engaged with the slide groove 511.

[0054] It should be noted that one side of the connecting protrusion 6 is fixed to the outer peripheral wall of the base 3, and the other side of the connecting protrusion 6 is in contact with the wall of the culture cylinder 1; through the above arrangement, the position of the base 3 in the culture cylinder 1 can be determined to prevent the base 3 from sliding left and right in the culture cylinder 1. The thickness of the connecting protrusions 6 at the two sides of the base 3 that are perpendicular to each other may be different, and connecting protrusions 6 of different thicknesses can be selected according to actual conditions.

[0055] The connecting bolt 7 in the present application does not have a nut, and the outer peripheral wall of the connecting bolt 7 has an external thread, and the outer end of the connecting bolt 7 has a hexagonal hole, so that the operator can rotate the connecting bolt 7 with an Allen wrench; in the initial state, all the connecting bolts 7 are located in the threaded hole; during the plug-in process of the enclosure 4 and the base 3, interference of the connecting bolts 7 can be avoided; when the enclosure 4 needs to be removed, the base 3 and the enclosure 4 are both located outside the culture tank 1, so the operator can rotate the connecting bolt 7 with an Allen wrench, and make the connecting bolt 7 push the plug-in plate 52, so that the plug-in plate 52 produces elastic deformation, and then the clamping part 54 is separated from the top of the connecting frame 51; through the above arrangement, it is easy to pull the enclosure 4 out of the base 3; because the connecting bolt 7 is located in the slide groove 511, the connecting bolt 7 will not affect the sliding of the connecting frame 51.

[0056] In some embodiments, Figures 1 to 9 As shown, a sealing gasket is connected to the outer peripheral wall of the plug-in part of the enclosure 4. When the enclosure 4 and the base 3 are plugged into place, the sealing gasket abuts against the inner peripheral wall of the base 3.

[0057] It should be noted that the sealing gasket is located below the connection frame 51 ; by providing the sealing gasket on the outer peripheral wall of the enclosure 4 , the sealing performance between the enclosure 4 and the base 3 can be improved after the enclosure 4 and the base 3 are plugged in and matched.

[0058] In some embodiments, Figures 1 to 9 As shown, the base 3 is connected to a plurality of connecting protrusions 6 along its circumference, and each connecting protrusion 6 is connected to a first sling (not shown in the figure); wherein, a guide ring 41 for the first sling to pass through is provided on the outer peripheral wall of the enclosure 4.

[0059] It should be noted that a lifting hole 61 is provided on the connecting protrusion 6, one end of the first sling passes through the lifting hole 61, and the protruding end of the first sling is fixed to the first sling through a fixing member; by providing a guide ring 41 on the outer peripheral wall of the enclosure 4, a guiding function can be played for the first sling, and during the lifting process, the overturning of the enclosure 4 can be reduced, thereby improving safety performance.

[0060] In some embodiments, Figures 1 to 9 As shown, an anti-slip sling (not shown in the figure) is fixedly provided on the first sling, and an anti-slip plate 8 is fixedly provided on the other end of the anti-slip sling; an anti-slip groove 62 is provided on the top of the connecting protrusion 6, and the anti-slip plate 8 is plugged into the anti-slip groove 62; wherein, the connecting protrusion 6 has a threaded through hole connected to the anti-slip groove 62, and the anti-slip plate 8 has a plug hole, and the plug hole is aligned with the threaded through hole; the connecting protrusion 6 has a connecting bolt 7, the connecting bolt 7 is threadedly matched with the threaded through hole, and the connecting bolt 7 is plugged into the anti-slip plate 8.

[0062] It should be noted that, when the lifting point of the first sling bears the tension, the anti-slip sling is in a relaxed state, so the anti-slip sling is not subjected to force; when the lifting point of the first sling breaks, the anti-slip sling is in a straightened state and bears the tension.

[0063] In addition, when the enclosure 4 is not placed in the culture cylinder 1, the top of the first sling is located outside the culture cylinder 1; when the enclosure 4 needs to be placed in the culture cylinder 1, the first sling is first passed through the guide ring 41 on the outer wall of the enclosure 4, and then the enclosure 4 is plugged into the base 3.

[0064] In some embodiments, Figures 1 to 9 As shown, the cultivation equipment also includes an illuminating lamp (not shown in the figure) arranged above the culture cylinder 1. A supporting frame (not shown in the figure) is provided on the top of the culture cylinder 1, and the illuminating lamp is installed on the supporting frame.
