Description

Technical Field

[0001] This invention relates to the field of aquaculture, and in particular to a device for cultivating the filamentous shells of *Porphyra yezoensis*. Background Technology

[0002] In the seedling stage of *Porphyra yezoensis* filaments, shells are typically used as the substrate for cultivation. Currently, there are two methods for arranging the shells for cultivating *Porphyra yezoensis* filaments: one is to string the shells together with nylon thread and suspend them. This method involves a relatively cumbersome initial threading process, and later, impurities such as algae or soil adhering to the shell surface that affect the attachment and growth of the *Porphyra yezoensis* filaments need to be manually brushed off, which is time-consuming and labor-intensive; the other method is to lay the shells flat in the cultivation pond for cultivation. This method occupies a large space and also requires manual removal of impurities later, which is also time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cultivation device for the filamentous shells of *Porphyra yezoensis*. The device uses a conveying structure to arrange and transport the cultivation platforms, making full use of the cultivation space. It also uses an automatic cleaning mechanism to clean the shells on the water surface, replacing manual labor, improving operational efficiency, and reducing labor costs.

[0004] The present invention adopts the following technical solution: a high-efficiency laver shell attachment substrate placement device, including a culture box and a culture platform set in the culture box. The culture platform is set by a conveying mechanism, which can be raised and lowered in the culture box and can expose the culture platform above the culture water level. A cleaning mechanism for brushing the shells on the culture platform is set above the culture box.

[0005] The conveying mechanism includes a rectangular track, several movable seats evenly arranged in the rectangular track, a transmission chain connected to the movable seats, and a drive motor connected to the transmission chain via a transmission shaft. The number of breeding platforms and movable seats are installed one-to-one. The left and right vertical sides and the bottom horizontal side of the rectangular track provide a place for the breeding platforms to stop, forming several breeding positions for placing shells. The top horizontal side of the rectangular track provides a place for the breeding platforms to stop, forming a washing position for brushing the shells. When the drive motor starts, it drives the transmission chain and movable seats to adjust the position of the breeding platforms and transport the breeding platforms that need to be washed to the washing positions.

[0006] The cleaning mechanism includes several rotating brush heads arranged in a matrix, with an elastic abutment in the middle of each brush head. The brush heads are mounted on rotating cylinders, which are mounted on a lifting frame. The lifting frame is raised and lowered by the rotating cylinders. The culture platform has placement points arranged in a matrix, with each placement point corresponding to a shell. When the culture platform to be cleaned is in the cleaning position, the lifting cylinders are activated to drive the lifting frame, rotating cylinders, and rotating brush heads to descend synchronously, causing the elastic abutment to contact the shell. When the rotating cylinders are activated, the rotating brush heads rotate to clean the shells.

[0007] As an improvement, three breeding positions are set on each of the left and right vertical sides of the rectangular track along the height direction, one breeding position is set in the middle of the lower horizontal side of the rectangular track, and one washing position is set in the middle of the upper horizontal side of the rectangular track.

[0008] As an improvement, an offset brushing station is set relative to the brushing station. The offset brushing station is 1-2cm away from the brushing station. After the breeding platform that needs to be brushed has completed one brushing at the brushing station, the drive motor transports the breeding platform to the offset brushing station for another brushing, thereby covering the elastic abutment parts that were not brushed at the brushing station.

[0009] As an improvement, the rotating brush head is circular and has annular bristles. The elastic abutment is located at the annular position of the bristles, and the bristles are longer than the elastic abutment, so that the bristles fully contact the shell surface when the elastic abutment contacts the shell.

[0010] As an improvement, the breeding box is equipped with magnetic impellers at the bottom and the middle of the rectangular track, and ventilation pipes are arranged corresponding to the magnetic impellers. When gas is introduced into the pipes and the magnetic impellers are activated, oxygen supply to the breeding environment is promoted.

[0011] As an improvement, light sources are installed around the breeding boxes to provide illumination.

[0012] As an improvement, a water quality sensor is also installed in the breeding tank, and inlet and outlet water outlets are set at opposite corners of the breeding tank.

[0013] The beneficial effects of this invention are:

[0014] 1. Make full use of the depth of the breeding box and effectively rely on several breeding platforms at different depths to lay shells for breeding, so as to make better use of space and achieve better breeding results.

[0015] 2. The arrangement and transportation of the breeding platforms are carried out through a conveyor structure, making the arrangement of the breeding platforms more labor-saving and efficient.

[0016] 3. The cleaning mechanism automates the washing of shells on the aquaculture platform, freeing up labor and saving human resources.

[0017] 4. Alternating between multiple culture sites and washing sites facilitates effective observation and recording of the culture status of the filamentous shells of *Porphyra yezoensis*. Attached Figure Description

[0021] Figure 4 This is a top view of the aquaculture platform of the present invention. Detailed Implementation

[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 The image shows a specific embodiment of the Laver Shell Filament Aquaculture Equipment of the present invention.

[0024] This embodiment includes a culture box 1 and a culture platform 2 set in the culture box 1. The culture platform 2 is set by a conveying mechanism 3, which can be raised and lowered in the culture box 1 and can expose the culture platform 2 above the culture water level. A cleaning mechanism 4 is set above the culture box 1 to brush the shells on the culture platform 2.

[0025] The conveying mechanism 3 includes a rectangular track 31, several movable seats 32 evenly arranged in the rectangular track 31, a transmission chain 33 connected to the movable seats 32, and a drive motor 34 connected to the transmission chain 33 via a transmission shaft. The number of breeding platforms 2 and movable seats 32 are installed one by one. The left and right vertical sides and the lower horizontal side of the rectangular track 31 are used for the breeding platforms 2 to stop, forming several breeding positions for placing shells. The upper horizontal side of the rectangular track 31 is used for the breeding platforms 2 to stop, forming a washing position for washing shells. When the drive motor 34 starts, it drives the transmission chain 33 and the movable seats 32 to work together, adjust the position of the breeding platforms 2, and convey the breeding platforms 2 that need to be washed to the washing positions.

[0026] The cleaning mechanism 4 includes several rotating brush heads 41 arranged in a matrix. An elastic abutment 42 is provided in the middle of the rotating brush head 41. The rotating brush head 41 is mounted on a rotating cylinder 43. Several rotating cylinders 43 are mounted on a lifting frame 44. The lifting frame 44 is raised and lowered by a lifting cylinder 45. Placement points 21 are arranged in a matrix on the breeding platform 2. Placement points 21 are used for corresponding placement of shells. When the breeding platform 2 to be cleaned is in the cleaning position, the lifting cylinder 45 is activated to drive the lifting frame 44, rotating cylinders 43 and rotating brush heads 41 to descend synchronously, so that the elastic abutment 42 abuts against the shell. When the rotating cylinder 43 is activated, the rotating brush head 41 rotates to clean the shell.

[0027] In use, the brushing position also serves as the feeding and unloading position for the seashells. Aquaculture personnel can manually or automatically place the seashells onto the matrix-arranged placement points 21. This placement ensures effective spacing between the seashells and aligns them with the matrix-arranged rotating brush heads 41 in the cleaning mechanism 4. After placement, the drive motor 34 is activated to transport the cultivation platform 2 into the cultivation box 1 for the cultivation of the filamentous structures of the *Porphyra yezoensis* seashells. The left and right vertical sides and the lower horizontal side of the rectangular track 31 form a sufficient number of cultivation positions. (Refer to...) Figure 1 Using a suitable culture tank 1, the depth of the tank is fully utilized to lay and cultivate shells at different depths, making better use of space and achieving better cultivation results. The culture water may contain silt and other algae, which will deposit or grow on the surface of the shells during the cultivation of *Porphyra yezoensis* shell filaments, thus affecting the normal growth of the shell filaments. The *Porphyra yezoensis* shell filaments will penetrate into the calcareous layer of the shell. Ordinary brushing will not damage the *Porphyra yezoensis* shell filaments already attached to the shell, but it can effectively remove silt and other algae.

[0028] When regular shell cleaning is required, the aquaculture personnel activate the external drive motor 34, which transmits power to the transmission chain 33 via the existing transmission shaft structure. This causes the transmission chain 33 to run, which in turn drives the movable seat 32 along the rectangular track 31, moving the aquaculture platform 2 closest to the cleaning position to the cleaning position. Afterward, the aquaculture personnel can activate the cleaning mechanism 4. Specifically, the lifting cylinder 45 drives the lifting frame 44 to descend, causing the rotating cylinder 43 and rotating brush head 41 to descend synchronously to the elastic contact member 42 to contact the shell. The matrix-arranged rotating brush heads 41 position the shells at their corresponding locations. Then, the rotating cylinder 43 is activated, and the rotating brush head 41 rotates to effectively clean the shells. After cleaning is completed, the cleaning mechanism 4 resets, and the shells on the next aquaculture platform 2 can then be cleaned. The conveying and cleaning processes are mechanized, saving manual labor and resulting in higher efficiency and more thorough cleaning. The alternation between multiple culture stations and washing stations allows culture personnel to effectively observe and record the culture status of the seaweed shell filaments in the washing station, and to promptly replace each culture station so that the cultivated seaweed shell filaments can proceed to subsequent processing.

[0029] As an improved specific implementation, three breeding positions are set on each of the left and right vertical sides of the rectangular track 31 along the height direction, one breeding position is set in the middle of the lower horizontal side of the rectangular track 31, and one washing position is set in the middle of the upper horizontal side of the rectangular track 31.

[0030] like Figure 1As shown, considering the rational use of space, control of overall volume, and control of equipment width, three breeding positions are set on each of the left and right vertical sides along the height direction, one breeding position is set in the middle of the lower horizontal side, and there is a four-layer breeding space. The middle of the uppermost horizontal side is used as a washing position, which can better balance the equipment height, the number of breeding, and the control of factors such as light and oxygen supply.

[0031] As an improved specific implementation, an offset brushing station is set relative to the brushing position. The offset brushing station is 1-2cm away from the brushing position. After the breeding platform 2 that needs to be brushed completes one brushing at the brushing position, the drive motor 34 transports the breeding platform 2 to the offset brushing station for another brushing, thereby covering the elastic abutment 42 that was not brushed at the brushing position.

[0032] like Figure 2 , 3 As shown, in order to achieve proper positioning of the rotating brush head 41 and the shell for effective brushing, an elastic abutment 42 is provided in the middle to form a structural positioning with the shell. In specific implementation, the elastic abutment 42 can be rotatably set in the middle of the rotating brush head 41 by means of a bearing. After the elastic abutment 42 abuts the shell, the pressure of the lifting cylinder 45 keeps the shell and the elastic abutment 42 as a relatively stationary whole, and the rotating brush head 41 is driven by the rotating cylinder 43 to brush the surface of the shell. The elastic contact 42 cannot be brushed during the current brushing process, and due to the differences in shell size, the rotating brush head 41 may not be able to completely brush the entire surface of the shells. Furthermore, the movement trajectory of the rotating brush head 41 remains unchanged during a single brushing, which may result in some stubborn algae not being brushed off. Therefore, an offset brushing station is further set up, 1-2 cm away from the main brushing station. After one brushing cycle at the main brushing station, the culture platform 2 moves to the offset brushing station for another brushing cycle. At the offset brushing station, the elastic contact 42 will abut against another shell location (e.g., ...). Figure 2 , 3 (As shown in the comparison), the areas that were not brushed before can be brushed by the rotating brush head 41 in this brushing. Due to the change in position, the rotating brush head 41 contacts the shell at a completely new angle. This brushing can more thoroughly clean the areas of the shell that may not have been brushed or cleaned before, achieving a better brushing effect.

[0033] As an improved specific implementation, the rotating brush head 41 is circular and has annular bristles. The elastic contact member 42 is located at the annular position of the bristles, and the bristles are longer than the elastic contact member 42, so that the bristles fully contact the shell surface when the elastic contact member 42 contacts the shell.

[0034] like Figure 2 , 3As shown, the ring-shaped bristles are longer than the elastic contact member 42, allowing them to fully contact the shell surface and achieve a better cleaning effect during rotating brushing.

[0035] As an improved specific implementation, the breeding box 1 is equipped with a magnetic impeller 5 at the bottom and the middle of the rectangular track 31, and a ventilation pipe 6 is arranged corresponding to the magnetic impeller 5. When gas is introduced into the pipe 6 and the magnetic impeller 5 is activated, the oxygen supply to the breeding environment is promoted.

[0036] like Figure 1 As shown, since sufficient oxygen supply needs to be considered when cultivating the filamentous shells of *Porphyra yezoensis* at different depths, magnetic impellers 5 are installed at the bottom and middle positions, and gas is introduced through pipes 6. When the magnetic impellers 5 are activated, they will stir and mix the gas and liquid, allowing oxygen to mix into the culture water and diffuse to the entire culture area in the liquid stirring and circulation, thus achieving the effect of oxygen supply to different positions.

[0037] As an improved specific implementation, a light source 7 is provided around the breeding box 1 to provide illumination.

[0038] like Figure 1 As shown, sufficient light needs to be considered when cultivating the filamentous shells of *Porphyra yezoensis* at different depths. Light sources 7 are set around the cultivation box 1 to illuminate different locations. As an optimization, light sources 7 can be set at different heights to improve the lighting effect and promote the growth of the filamentous shells of *Porphyra yezoensis*.

[0039] As an improved specific implementation, the breeding tank 1 is also equipped with a water quality sensor 8, and the breeding tank 1 has an inlet and outlet 9 located diagonally.

[0040] like Figure 1 As shown, relying on the installed water quality sensor 8, the water quality can be fed back to the aquaculture personnel or the automated control system. The aquaculture personnel can then change the aquaculture water, or the control system can automatically control the opening and closing of the inlet and outlet 9 to change the water. Specifically, the inlet and outlet 9 can be set diagonally, with the inlet at a higher position and the outlet at a lower position, thereby promoting water circulation during water changes and facilitating the discharge and replacement of wastewater.

[0041] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
