[0065] Now, refer to Figures 1 to 7 Exemplary embodiments according to the present invention will be described in more detail below.

[0066] First Implementation Method

[0067] refer to Figure 1 and Figure 2 The first embodiment of this application provides a crab farming device 100, which includes a box body 101, a flushing section 110, and a sewage discharge section 120. The box body 101 has a first end 102 and a second end 103 opposite to each other along a first horizontal direction D1. The flushing section 110 is located in the box body 101 and is disposed at the first end 102. The flushing section 110 is provided with a first water passage structure and a water inlet 116. The sewage discharge section 120 is located in the box body 101 and is disposed at the second end 103. The sewage discharge section 120 is provided with a second water passage structure and a drain outlet 127. A farming area 130 is formed between the flushing section 110 and the sewage discharge section 120. The farming area 130 is used to set a sandy layer. The farming area 130 is fluidly connected to the flushing section 110 through the first water passage structure and to the sewage discharge section 120 through the second water passage structure.

[0068] According to the crab farming device of this application, by setting up flushing and sewage discharge sections on both sides of the farming area, the water flow with a certain kinetic energy is used to continuously flush the surface of the sand layer in the horizontal direction, which can remove the dirt on the surface of the sand layer without causing the sand layer to be washed away, thus helping to maintain the cleanliness of the water.

[0069] Specifically, the box body 101 includes a bottom wall 104 and side walls 105 surrounding the bottom wall 104. The flushing section 110 includes a first partition 113, which, together with the box body 101, forms a flushing area 111, and a water inlet 116 is disposed in the flushing area 111. Optionally, a water inlet pipe is disposed in the flushing area 111, and the opening of the water inlet pipe forms the aforementioned water inlet 116. The first water passage structure includes a plurality of flushing holes 112, which are disposed on the first partition 113. The plurality of flushing holes 112 are arranged along a second horizontal direction D2, wherein the second horizontal direction D2 is perpendicular to the first horizontal direction D1. The breeding area 130 is connected to the flushing area 111 through the flushing holes 112.

[0070] Preferably, the first partition 113 is generally L-shaped, and includes a first side panel 115 and a first top panel 114. The first side panel 115 is connected to the bottom wall 104 of the box body 101 and spaced apart from the side wall 105 of the box body 101. The first top panel 114 is connected between the top of the first side panel 115 and the side wall 105 of the box body 101. A flushing hole 112 is provided on the upper part of the first side panel 115. As an example, 20-30 flushing holes 112 can be provided on the first partition 113.

[0071] The sewage discharge section 120 includes a second partition 124, which, together with the housing 101, forms a sewage discharge area 121. A drain outlet 127 is disposed in the sewage discharge area 121. Optionally, a drain pipe is provided in the sewage discharge area 121, with the opening of the drain pipe forming the aforementioned drain outlet 127. The second water passage structure includes a plurality of first sewage discharge holes 122, which are disposed on the second partition 124 and arranged along a second horizontal direction D2. The aquaculture area 130 is connected to the sewage discharge area 121 through the first sewage discharge holes 122. A forced sewage discharge pipeline may also be provided in the sewage discharge section 120. The forced sewage discharge pipeline can be opened and closed to connect to the outside, thereby allowing the water in the housing 101 to be replaced through the forced sewage discharge pipeline.

[0072] Preferably, the second partition 124 is generally L-shaped, and includes a second side panel 126 and a second top panel 125. The second side panel 126 is connected to the bottom wall 104 of the box body 101 and spaced apart from the side wall 105 of the box body 101. The second top panel 125 is connected between the top of the second side panel 126 and the side wall 105 of the box body 101. A first drain hole 122 is provided on the first top panel 114.

[0073] Thus, water is injected into the flushing area 111 through the inlet 116. The water flows out from the flushing hole 112, flows through and washes the surface of the sandy layer in the aquaculture area 130, and carries pollutants into the sewage area 121 through the first sewage outlet 122, and finally out of the box 101 through the drain outlet 127. In this way, a flushing water flow is formed along the first horizontal direction D1. As water is continuously injected through the inlet 116, the flushing water flow continuously washes the surface of the sandy layer. In addition, the flow path of the flushing water flow runs through the entire box 101, which can carry away most of the pollutants and there are almost no dead water areas.

[0074] In one implementation, the crab farming device 100 also includes a filter (not shown) and a pump (not shown). The filter is connected to the wastewater discharge area 121, specifically to the drain outlet 127, to receive and filter wastewater. The pump is connected to the filter and also to the flushing area 111. Specifically, the pump is also connected to the inlet 116, allowing for continuous water injection into the flushing area 111, so that the water in the flushing area 111 can flow at a rate of 3-5 m. 3 A flow rate of / h flows out of the flushing hole 112, thus having sufficient impact force to carry away dirt. The pump device can be installed on the pipeline between the drain outlet 127 and the filter device, or on the pipeline between the inlet 116 and the filter device.

[0075] In summary, the flushing area 111, the aquaculture area 130, the sewage discharge area 121, the filtration device, and the pump device form an internal water circulation system, continuously circulating and filtering the sewage for reuse.

[0076] Continue to refer to Figure 1 and Figure 2 The aquaculture area includes a sedimentation space 132 and an aquaculture space 131. The aquaculture space 131 is at least partially located above the sedimentation space 132. The second water passage structure also includes multiple second drain holes 123. The second drain holes 123 are disposed on the second partition 124, and the position of the second drain holes 123 is lower than that of the first drain hole 122. The first drain hole 122 connects the aquaculture space 131 and the drain area 121, and the second drain holes 123 connect the sedimentation space 132 and the drain area 121. The second drain holes 123 can be located at the bottom of the second side panel 126 of the second partition 124, for example... Figure 5 As shown, a toothed structure can be formed at the bottom of the second side panel 126, thereby forming a row of second drain holes 123 spaced apart along the second horizontal direction D2.

[0077] In this embodiment, the aforementioned sedimentation space 132 is formed by a support plate 140, with the upper part of the support plate 140 used to support the sandy layer. Specifically, the support plate 140 is located in the aquaculture area 130, and is at least partially spaced from the bottom plate of the box 101, thereby forming the sedimentation space 132 between the support plate 140 and the bottom plate. The support plate 140 is provided with water passage holes 141, allowing some pollutants to permeate downwards from the sandy layer and enter the sedimentation space 132 through the water passage holes 141, thereby preventing the accumulation of pollutants in the sandy layer.

[0078] Preferably, the support plate 140 is inclined relative to the bottom plate, and the two ends of the support plate 140 along the first horizontal direction D1 are respectively connected to the first partition 113 and the second partition 124, and the end of the support plate 140 connected to the second partition 124 is higher than the end of the support plate 140 connected to the first partition 113.

[0079] The box body 101 also includes a water level control unit 150, which is provided with an overflow outlet 152, the height of which limits the water level.

The water level control unit 150 can be provided at the end of the box 101 on one side along the second horizontal direction D2.

[0081] In one implementation, the water level control unit 150 can be an overflow pipe located at a certain height, with an overflow outlet on the overflow pipe. Excess water will flow out from the overflow outlet, controlling the water level at the height of the overflow pipe opening. Preferably, the water level control unit 150 is constructed as an overflow plate 151, with an overflow outlet 152 on the overflow plate 151, and the height of the overflow plate 151 limits the water level. The overflow plate 151 can be horizontally positioned.

[0082] refer to Figure 2 The crab farming device 100 also includes a drain plate 160 and a crawling plate 161, both of which are installed in the farming area 130. The drain plate 160 has multiple drainage holes and is connected to the side wall 105 of the container 101. The drain plate 160 is positioned above the water surface and above the overflow outlet 152, thus creating a relatively dry surface and a waterless area for crabs to move in. The crawling plate 161 is connected to the drain plate 160 and is inclined downwards relative to it. Preferably, the end of the crawling plate 161 extends to near the height of the sandy layer, allowing crabs to move onto the waterless area of ​​the drain plate 160. Preferably, the drain plate 160 and the crawling plate 161 are integrally constructed and are connected to the side wall 105 of the container 101 by bolts or other fasteners.

[0083] The crab farming device 100 also includes a lid 106, such as Figure 7 shown ( Figure 7 (Although the example shown is not of the first embodiment, the lid 106 can also be applied in this embodiment.) The lid 106 is closable and can be installed on the box body 101 to prevent the crab from escaping from the top. An observation port 107 is provided on the lid 106.

The sandy layer is only provided in the carrier box 240 and does not cover the entire farming area 130. The portion of the farming area 130 outside the carrier box 240 forms a deep-water space 133 to provide a deep-water activity area for the crabs.

[0087] The sedimentation space 232 is formed by a support box 240, which is spaced apart from the bottom plate of the box body 101. A water passage hole 241 is provided at the bottom of the support box 240, thereby forming the sedimentation space 232 between the support box 240 and the bottom plate. The deep water space 133 is connected to the sedimentation space 132, so the second drain hole 123 is connected to the sedimentation space 132 through the deep water space 133.

[0088] Specifically, a support block 243 is provided on the bottom plate of the box body 101, and the carrier box 240 is detachably mounted on the support block 243. To facilitate the handling of the carrier box 240, a grip portion 242 is preferably provided on the carrier box 240. As an example, the grip portion 242 can be constructed as a groove for a person's hand to enter. Preferably, the carrier box 240 is disposed adjacent to the first partition 113, and correspondingly, the support block 243 needs to be disposed close to the first partition 113, so that the flushing water flowing out from the flushing hole 112 can directly flush the surface of the sand layer.
