The bottom plate 11 is configured to extend from the rear plate 13 along the side plates to the front plate 12 with an inclination greater than 1:200. In the actual breeding process, multiple breeding boxes are assembled and superimposed sequentially from top to bottom to achieve large-scale breeding requirements. The upper end of the front plate 12 of the breeding box body 1 is detachably connected with an upper baffle, and the front plate 12 is shorter and extends obliquely outwards. The user can directly take out the upper baffle so as to facilitate the user's real-time observation. The front plate 12 forms a V-shaped structure, and the upper baffle is provided with a feeding port, so that the user's feeding can effectively prevent the crabs from crawling out of the open chamber, and the user himself can directly observe the status of the crabs through the feeding port. The left and right side plate tops of the culture box body 1 are all provided with openings, and the openings are used for the introduction of water pipes. If necessary, liquid water can be directly introduced into the opening chamber by passing the external water pipes through the openings.

The upper drainage unit 2 is located in the open chamber, and the upper drainage unit 2 communicates with the drainage hole provided at the bottom of the open chamber, and the upper drainage unit 2 is a siphon generating device. The siphon generating device includes a bottom overflow device and a siphon cover plate 24 connected to the upper end of the bottom overflow device. The bottom overflow device includes an inner pipe 21 , an outer pipe 22 sleeved on the inner pipe 21 , and a plurality of connecting parts connecting the inner pipe 21 and the outer pipe 22 . The inner tube 21 is provided with a drainage channel 6 whose lower end communicates with the drainage hole, and an upper gap channel 7 for liquid flow is provided between the upper end of the inner tube 21 and the siphon cover plate 24 . The upper end of the outer tube 22 is sealed and connected to the siphon cover plate 24. There is a gap between the water inlet provided at the lower end of the outer tube 22 and the bottom of the opening chamber. The height value of the gap is set by the farmer according to the water level required by the breed. Currently, it is When the height of the gap is 5-20mm, the cleaning effect is the best. An outer gap channel 8 for liquid flow is provided between the outer tube 22 and the inner tube 21. The outer gap channel 8 communicates with the open chamber, and the outer gap channel 8, the upper gap channel 7, and the drainage channel 6 are connected in sequence. A siphon generation channel for siphon generation is formed. The lower end of the outer tube 22 corresponding to the bottom of the open chamber is the water inlet position of the siphon generating device, and the user can set the height of the water inlet apart from the open chamber according to the required water level of the cultured species. The outer tube 22 is provided with a water inlet hole 9 radially connected to the open chamber, and the inner end of the water inlet hole 9 is connected to the outer gap channel 8 . The diameter of the water inlet hole 9 is larger than 3mm.

Principle: When the water level of the box is higher than the inner pipe 21, the water in the box enters from the water inlet and flows from the inner pipe 21 to the lower drainage unit 3 through the drainage channel 6. When the water flow is small, the flowing water forms a natural drainage state. When the water When the flow rate increases, the air in the siphon cavity will also be discharged, forming a vacuum state, and the siphon effect occurs. At this time, the water flow discharged by the siphon device is greater than the water intake of the box, and the water level of the box continues to drop. When it falls to the siphon device When the water inlet is at the water inlet level, a large amount of air is sucked from the water inlet, destroying the siphon effect, and when the siphon ends, the water level of the box begins to rise, and the cycle repeats.

The connecting parts shown in Figure 3-6 are three connecting plates 23 radially connected to the outer wall of the inner tube 21, and there is a gap between the three connecting plates 23, which is the filter port, opening the liquid in the chamber. First pass through the filtering port and then enter the upper gap channel 7 and the outer gap channel 8, thereby preventing the siphon from clogging the channel. In addition, the opening of the filter port of this patent is vertically downward, so that the adhesion on the filter port will directly slide down and fall under the action of gravity, which improves the self-cleaning effect of the filter port.

The upper end of the outer tube 22 is sealed and connected to the siphon cover plate 24, which can be connected in one piece as shown in Figure 4, or can be connected with a detachable screw thread as shown in Figure 5, or can also be connected as shown in Figure 5. The detachable buckle connection shown in 6 allows the user to disassemble the siphon cover 24 in real time to clean the siphon generating device.

As shown in Figure 2, the lower drainage unit 3 is a curved pipe, which is composed of a 90° elbow connected to another 90° elbow through a straight pipe section, and is installed under the drain hole. The lower end of the curved tube is located above the opening chamber of the next culture box, and the lower end of the bent tube is close to the rear plate 13 side of the next culture box. Since the bottom plate 11 slopes downward from the rear plate 13 to the front plate 12, the inclination is greater than 1:200, and the curved pipe injects water on the side of the rear plate 13, so that the water flow covers and cleans the bottom surface of the larger open chamber. Under the action of the water flow, feed residues and aquatic product excreta collect on the side of the front plate 12 and enter the sewage tank, which is convenient for the user to intuitively observe the cleaning status of the opening chamber in the breeding box in real time.

On the base plate 11 near the front plate 12, there are sewage grooves, sewage holes and drainage holes. The bottom plate 11 is inclined downward along the direction of the sewage discharge groove 5 , so that the residue stains directly flow into the sewage discharge groove 5 with the water flow. The upper drainage unit 2 is installed on the upper side of the base plate 11, the lower drainage unit 3 is installed on the lower side of the base plate 11, the sewage unit 4 is installed above the sewage hole, and the position of the sewage outlet on the sewage unit 4 is higher than the top of the upper drainage unit 2 and lower than the top of the upper drainage unit 2. on the front panel 12.

The sewage discharge unit 4 is a funnel-shaped structure with a large top and a small bottom, and the sewage discharge unit 4 is connected to a sewage discharge port. The sewage outlet has a downwardly extending cylindrical extension, and the inner side of the cylindrical extension forms a thread fit with the sewage unit 4 to ensure the sealing of the colony box body 1 . In addition, plug-in fit can also be used. If plug-in fit is used, a sealing ring can be added inside the cylindrical extension to improve the sealing performance of the product. The existence of the cylindrical extension also increases the contact area between the sewage discharge unit 4 and the colony box body 1 , and improves the stability of the sewage discharge unit 4 . The sewage discharge unit 4 is detachably installed in the open cavity. When there is too much residue in the sewage discharge tank, the drainage unit of the culture box body 1 is taken out, and the liquid in the open cavity is directly discharged from the sewage outlet into the next culture box body 1 The upper side of the sewage discharge unit 4, and pass down the funnel to the outside in turn.

As shown in FIG. 7 , compared to Embodiment 1, Embodiment 2 has increased the structure of a partition 10 and a sandy layer 012 . The partition 10 is clamped and fixed in the slot 011 provided in the opening chamber, and the partition 10 divides the opening chamber into a first area and a second area, and a sandy layer is provided in the first area. 012, the height of the partition 10 is slightly higher than the sandy layer 012, so as to facilitate the crawling of crabs from the first area and the second area. The upper surface of the sandy layer 012 is fine sand, simulating the living conditions of crabs in nature, avoiding wear and tear on the bottom of the crabs, and improving the appearance of the crabs.

Specific operation method: when the water level of the box is higher than the inner pipe 21, the water in the box enters from the water inlet and flows from the inner pipe 21 to the lower drainage unit 3 through the siphon channel. When the water flow Q is small, the flow Q<0.8 L/min, the flowing water forms a natural drainage state, and a small part of the air in the siphon cavity will be discharged. The probability of siphon phenomenon is small or it takes a long time for siphon phenomenon to occur. When the water flow Q increases, the flow rate is 0.8L /min<Q<2L/min, part of the air in the siphon cavity will be discharged, and the vacuum state will take a long time, and there is a certain probability that the siphon effect will occur. When the water flow Q increases, the flow Q>2L/min , a large amount of air in the siphon generation chamber will be discharged, forming a vacuum state, and a siphon effect occurs. The suction force generated by the siphon effect simultaneously absorbs feed residues and aquatic product excrement. At this time, the water flow discharged by the siphon device is greater than that of the box. The water intake, the water level of the box keeps dropping, when it drops to the position of the water inlet hole 9 of the siphon device, the air is sucked from the water inlet hole 9, destroying the siphon effect, the siphon ends, the box water level starts to rise, and the cycle repeats.
