Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a crab spawning and hatching device. Background Technology

[0002] Mud crabs are an important economic crab species for marine aquaculture in my country. Artificial breeding and spawning are key links in large-scale aquaculture. Mud crab spawning and hatching mainly use traditional cement ponds or fiberglass ponds, relying on artificial control of environmental parameters such as water quality, temperature, and dissolved oxygen to meet the needs of parent crabs for spawning and larval hatching.

[0003] Existing incubation devices are typically equipped with basic water circulation, oxygen supply, and temperature control systems to maintain a basic aquatic environment. However, the spawning and larval development of mud crabs have high requirements for water quality stability, dissolved oxygen uniformity, and light conditions. Traditional incubation ponds may face problems such as insufficient dissolved oxygen in local areas, uneven temperature distribution, or low water exchange efficiency during long-term operation. During the incubation process, shading or light transmission conditions need to be adjusted according to the light intensity. However, existing devices mostly use fixed shading nets or manually adjustable structures. Therefore, a mud crab spawning and incubation device is proposed to address the above issues.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a mud crab spawning and hatching device, including a cement pool 1, a water supply component 2, an air supply component 3 and a heating component 4. The cement pool 1 includes a pool body 101, a permeable stone slab 102 is provided at the bottom of the pool body 101, and a hole is opened at the bottom right side of the pool body 101, and a drain pipe 103 is provided in the hole.

[0024] In this embodiment, the cement pool 101 is designed with a length of 6m, a width of 4m, and a depth of 2m, providing ample living space for the mud crabs. The permeable stone slab 102 at the bottom of the pool 101 has a uniformly distributed microporous structure, which can effectively support the sediment at the bottom of the pool and allow for natural water infiltration, preventing the eggs from suffocating due to lack of oxygen caused by water accumulation. The drainage pipe 103 installed at the bottom on the right side forms a cooperative drainage system with the permeable stone slab 102. When water needs to be changed, sewage can be quickly collected through the micropores of the stone slab and discharged through the drainage pipe 103, while the eggs and larvae are blocked and protected by the permeable stone slab 102. This achieves efficient sewage discharge, avoids mechanical damage to the mud crab eggs and larvae, and improves the stability of the hatching environment.

[0025] The water supply component 2 includes a water quality sensor 201, which is located on the left side of the pool body 101. A water supply pipe 202 is fixedly connected to the water quality sensor 201, and a solenoid valve 203 is installed on the water supply pipe 202. The air supply component 3 includes a dissolved oxygen sensor 301, which is located on the front side of the pool body 101. An aeration pipe 302 is fixedly connected to one side of the dissolved oxygen sensor 301. Microporous aeration heads 303 are arrayed on the aeration pipe 302, which is located on the top of the permeable stone slab 102. The heating component 4 includes a temperature sensor 401, which is located on the front side of the pool body 101. A heating pipe 402 is fixedly connected to one side of the temperature sensor 401, and the heating pipe 402 is located on the inner wall of the pool body 101.

[0026] In this embodiment, the water supply component 2 constructs a closed-loop water quality management system through the coordinated operation of the water quality sensor 201, the water supply pipe 202, and the solenoid valve 203. The water quality sensor 201 monitors water temperature, salinity, pH, and other indicators in real time. When abnormal data is detected, it automatically adjusts the mixing ratio of the backup water source to ensure water quality stability. The solenoid valve 203, as the actuator, can intelligently open and close based on sensor data to achieve precise water exchange or replenishment. It can respond promptly to water quality fluctuations and avoid mass mortality caused by excessive ammonia nitrogen or insufficient dissolved oxygen. When the density of larvae increases in the later stages of hatching, the system can automatically increase the water exchange frequency to maintain water cleanliness and provide a continuous and stable growth environment for the mud crab larvae.

[0027] In this embodiment, the dissolved oxygen sensor 301 of the air supply component 3 is linked with the microporous aeration head 303 for distributed air supply. Aeration pipes 302 are evenly laid on the top of the permeable stone slab 102, and microporous aeration heads 303 are set at certain intervals on the aeration pipes 302. The distributed air supply method can make oxygen evenly distributed in the pond water, avoid local hypoxia, and provide sufficient and uniform dissolved oxygen for the mud crabs. The dissolved oxygen sensor 301 detects the oxygen content of the water in real time. When the value is lower than the set threshold, the system automatically starts the aeration program. The fine bubbles generated by the microporous aeration head 303 can greatly improve the oxygen mass transfer efficiency, meet the high dissolved oxygen requirements of mud crab larvae, and reduce the deformity rate of larvae caused by hypoxia.

[0028] In this embodiment, the heating component 4 consists of a temperature sensor 401 and a heating tube 402 forming an intelligent temperature control network. The temperature sensor 401 is embedded in the front of the pool body 101 and can monitor the water temperature distribution at multiple points, overcoming the problem of local overheating caused by traditional heating rods, ensuring that the temperature of the entire incubation space is balanced. During seasonal changes, the system can automatically compensate for changes in ambient temperature and provide a continuous and stable thermal environment for the crab eggs.

[0029] A movable component 5 is provided on the top of the pool body 101. A polycarbonate sheet 6 is fixedly connected to the inner side of the movable component 5. The movable component 5 includes a support block 501. A groove is opened on the inner side of the support block 501. A bidirectional screw 502 is provided in the groove. Two sliders 503 are provided on the bidirectional screw 502. T-blocks 504 are provided on both sliders 503. The polycarbonate sheet 6 includes a plate body 601. T-blocks 504 are fixedly connected to one side of the plate body 601. The plate body 601 is arrayed and snapped together. A slot 602 is provided on the right side of the plate body 601. A block 603 is provided on the left side of the plate body 601. The slot 602 cooperates with the block 603.

[0030] In this embodiment, the moving component 5 drives the slider 503 via the bidirectional screw 502 to achieve intelligent opening and closing control of the polycarbonate sheet 6. The bidirectional screw 502 in the support block 501 is driven by a motor, which drives the two sets of T-blocks 504 to move synchronously in opposite directions. The connection between the locking block 603 and the locking slot 602 of the polycarbonate sheet 6 ensures sealing and facilitates maintenance and replacement. When the weather is sunny, the roof polycarbonate sheet 6 can be opened to allow sunlight to directly irradiate the pond water, promoting the growth of plankton and providing natural food for the juvenile crabs. When the weather is inclement, the roof polycarbonate sheet 6 can be closed to protect the crabs and equipment. It can automatically adjust the light transmittance according to the light intensity to meet the juveniles' need for moderate light.
