Description

Technical Field

[0001] This utility model relates to the field of thorn eel cultivation technology, specifically a temperature-controlled seedling box for cultivating single-ring thorn eel seedlings. Background Technology

[0002] *Ulva unicinctus*, also known as sea cucumber, is an elongated cylindrical annelid, covered in hairless spines, and light yellow in color. Its main habitat is Yantai. Due to overfishing in recent years, the population of *Ulva unicinctus* has declined sharply, severely impacting the regeneration and recovery of its natural resources. Therefore, research on seedling propagation of *Ulva unicinctus* is needed to increase and restore its resources, further mitigating the ecological impact. A search revealed a method for the ecological cultivation of *Ulva unicinctus* disclosed in Chinese patent CN215992388U. The substrate includes a cultivation box, a cultivation cover, a base, and drainage holes. The cultivation box has a cultivation cover on top, and drainage holes are evenly distributed on the inner wall of the bottom of the cultivation box, penetrating the bottom of the cultivation box. A base is located directly below the drainage holes, with its top connected to the bottom of the cultivation box. A groove is formed on the upper surface of the base. A first water outlet pipe and a second water outlet pipe are respectively provided on the outer surfaces of the cultivation box and the base, and their positions are vertically aligned. This biomimetic *Ulva uniringii* growth substrate, by providing closely spaced drainage holes at the bottom of the cultivation box, drains water that cannot be discharged through the first water outlet pipe and removes dirt from the sand at the bottom of the cultivation box, preventing dirt from remaining in the sand and affecting the water quality environment of the cultivation box, thus ensuring the living environment of *Ulva uniringii*.

[0003] Currently, existing seedling boxes typically pile up Ulva monocranium seedlings inside. During the cultivation period, observation requires scooping out each Ulva monocranium individually, which is quite inconvenient. Furthermore, after the cultivation is complete, each Ulva monocranium also needs to be scooped out individually for transfer. Utility Model Content

[0004] To address the problem that existing seedling boxes are inconvenient for removing *Ulva unicinctus*, this invention provides a temperature-controlled seedling box for cultivating *Ulva unicinctus* seedlings.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A temperature-controlled seedling incubator for cultivating *Ulva single-ringed worm* seedlings includes a box body. Inside the box body, a lifting basket assembly is slidably raised and lowered. The lifting basket assembly includes a frame. A filter screen is embedded inside the frame. Handles are installed on both sides of the frame located on the filter screen. Notches are provided at the connection points between the two handles and the frame. Hooks for attaching the handles are installed on both sides of the inner wall of the box body.

[0006] Furthermore, a lid is hinged to the top surface of the box, and a strip-shaped opening is provided on the top surface of the lid, with a feeding hopper connected inside the strip-shaped opening.

[0007] The beneficial effects of adopting the above-mentioned further solutions are that the box lid can reduce the loss of water temperature inside the box, maintain temperature stability, and create a suitable constant temperature growth environment for seedlings; the feeding hopper on the top of the box lid can be used for feeding without opening the box lid, avoiding temperature fluctuations or the entry of external pollutants caused by opening the lid, and ensuring the stability of the cultivation environment; the strip-shaped opening design of the feeding hopper facilitates the even distribution of feed.

[0008] Furthermore, the feeding hopper includes a hopper body, and a diversion plate is installed inside the hopper body. The two sides of the diversion plate are respectively provided with spacing channels with the inner wall of the hopper body.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the diversion plate disperses the feed to the two-sided spacing channels, so that the feed falls evenly into the box from the channels, avoiding feed accumulation caused by a single drop point, ensuring that all seedlings can get food evenly, and promoting uniform seedling growth.

[0010] Furthermore, a lifting cover is engaged at the top of the bucket body.

[0011] The beneficial effects of adopting the above-mentioned further solution are that the lid can close the hopper when not feeding, preventing dust, debris and other pollutants from entering the tank and ensuring water quality; the lid adopts a snap-fit ​​connection method, which is convenient to open and close.

[0012] Furthermore, the bottom surface of the box is provided with a sewage discharge mechanism, which includes a sludge pump. The sludge pump is installed on the bottom surface of the box, and the input end of the sludge pump is connected to a sewage inlet pipe. One end of the sewage inlet pipe is connected to the bottom surface of the box, and the output end of the sludge pump is connected to a sewage discharge pipe.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the sewage discharge mechanism can promptly clean up the feces, uneaten feed and other waste generated during the seedling cultivation process: the sludge pump draws out the sludge and sewage deposited at the bottom of the tank through the sewage inlet pipe and discharges it through the sewage outlet pipe, avoiding the accumulation of waste that leads to water quality deterioration and reducing the risk of seedling diseases.

[0014] Furthermore, support feet for lifting the sludge pump are installed at the four corners of the bottom surface of the box.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the support feet raise the housing, providing installation and operating space for the sludge pump of the sewage discharge mechanism, and avoiding moisture and wear caused by direct contact between the sludge pump and the ground.

[0016] Furthermore, a latch is provided between the box body and the box lid.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the latch can firmly fix the lid to the box body, preventing the lid from loosening or opening due to vibration or collision, ensuring stable internal temperature, and preventing external pollutants from entering.

[0018] Furthermore, a thermometer is embedded in one side of the box, and the sensing end of the thermometer extends into the interior of the box. A water filling valve is connected to the side of the box away from the thermometer.

[0019] The beneficial effects of adopting the above-mentioned further solution are that the temperature sensor end is inserted into the box, which can monitor the water temperature in the box in real time and accurately, making it convenient for operators to grasp the temperature of the seedling environment in a timely manner. Furthermore, through the connection of the water inlet valve, the device can add liquid water of different temperatures into the box according to the growth needs of the *Ulva unicornu* seedlings, thereby achieving the function of adjusting the water temperature and ensuring a suitable temperature.

[0020] Compared with the prior art, the beneficial effects of this utility model are: This temperature-controlled seedling incubator for cultivating *Ulva single-ringed eel* larvae features a basket assembly and hooks for easy placement and removal of the larvae. The sliding basket assembly provides a dedicated cultivation space for the larvae, while an embedded filter allows for free water flow, ensuring adequate oxygen and nutrient supply for larvae growth and preventing escape. Handles on both sides facilitate lifting the basket assembly for easy observation of larvae growth or relocation of the cultivation environment. The handles are precisely attached to hooks on the inner wall of the incubator, ensuring stable fixation of the basket assembly and preventing displacement due to water movement. Furthermore, notches allow the frame and handles to pass smoothly through the hooks, ensuring accurate attachment of the handles inside the incubator. Attached Figure Description
