Technical Field

[0001] The present invention relates to offshore aquaculture equipment, in particular to a tidal flat aquaculture system suitable for tidal flat areas. Background Art

[0002] At present, the nearshore tidal flats in China are only suitable for tidal flat aquaculture projects and cannot be used for offshore fish farming. The main reason is that the tidal flat areas cannot store water and are easily affected by typhoon weather. Summary of the Invention

Specific implementation mode

[0021] The present invention will be described in detail below with reference to the accompanying drawings:

[0022] Figures 1-6 As shown: A tidal flat aquaculture system, which includes

[0023] An aquaculture device, which is a cylindrical structure 1 inserted into the tidal flat. A net is provided at the top of the cylindrical structure 1, and an anti-seepage cloth 2 is laid at the bottom of the cylindrical structure 1, thereby forming an aquaculture space;

[0024] A communicating vessel 3, with two ends located inside and outside the aquaculture device respectively, for controlling the water level height inside the aquaculture device.

[0025] The cylindrical structure, the net covering the top of the cylindrical structure and the anti-seepage cloth at the bottom enclose to form an area capable of aquaculture, and water can be stored in this area for aquaculture of fish.

[0026] During high tide, water and food are supplied to the aquaculture device. After the ebb tide, the replenished water remains in the aquaculture device, and the amount of seawater in the aquaculture device is controlled by the communicating vessel.

[0027] The cylindrical structure 1 includes a plurality of enclosing plates 11. The enclosing plates 11 are inserted into the tidal flat and enclose to form the cylindrical structure 1, and any adjacent enclosing plates 11 are hermetically connected to each other.

[0028] The enclosing plate 11 is a precast concrete plate, and criss-cross strengthening bars 111 are provided on the inner or outer side of the precast plate. This can increase the strength of the enclosing plate.

[0029] The left and right side surfaces of the enclosing plate 11 are inclined planes along the front-rear direction, and a sealing strip and locking screw holes are provided on the inclined planes. When actually connecting the enclosing plates, the locking screw holes of adjacent enclosing plates 11 are aligned, a screw rod 41 is directly inserted, and then locked with a nut 42. It should be noted that generally, two rows of locking screw holes are provided from the inside to the outside of the enclosing plate 11, and in order to ensure that the nut can fit with the enclosing plate 11, a notch needs to be added at the position of the enclosing plate 11 corresponding to the locking screw holes.

[0030] The cylindrical structure 1 further includes a plurality of extension pipes 12. A plurality of pipe grooves are formed on the top surface of the enclosing plate 11, and the extension pipes 12 are inserted into the pipe grooves. A surrounding net is suspended on the outer periphery of the extension pipes 12. The barrier net at the top of the cylindrical structure 1 is also placed at the opening above the extension pipes 12.

[0031] The communicating vessel 3 is a drainage channel 31. The water inlet of the drainage channel 31 is located inside the breeding device, and the water outlet of the drainage channel 31 is located outside the breeding device. A grid for preventing the escape of breeding organisms is provided at the water inlet.

[0032] The opening of the water inlet faces downward. This facilitates the discharge of sewage and old water close to the bottom layer.

[0033] The water inlet of the drainage channel 31 faces downward, and a sealing cover 32 is provided at the water inlet. One side of the sealing cover 32 is hinged to the drainage channel 31, and a first floating ball 33 is provided on the other side of the sealing cover 32 so that the sealing cover 32 always blocks the water inlet; a connecting rod 34 extends backward from the hinge of the sealing cover 32, and the end of the connecting rod 34 is connected to a second floating ball 36 by a rope 35; when the second floating ball 36 floats, it will overcome the buoyancy of the first floating ball 33 to open the sealing cover 32.

[0034] The specific usage method of the present invention is as follows:

[0035] The specific usage method of the present invention is as follows. Select a suitable place, and then insert the enclosing plates in sequence and enclose and connect them to form a cylindrical structure. Here, the depth of the enclosing plates inserted downward is approximately one-third of the height of the enclosing plates. This is convenient for fixing, reduces the cross-sectional area, and can reduce the impact of wind and waves. Then, dig downward at the bottom of the cylindrical structure until it is flush with the lower edge of the cylindrical structure, and then lay the anti-seepage cloth 2. Here, a certain depth of beach sand and gravel can be backfilled on the upper part of the anti-seepage cloth 2 for breeding the original beach organisms such as shellfish. After that, install the communicating vessel. Finally, install the extension pipes 12, hang the surrounding net on the extension pipes, and then lay the barrier net in the area above the extension pipes. Small floating balls can also be placed on the barrier net to ensure that the barrier net floats up during high tide, increasing the volume of the space formed by enclosing the cylindrical structure and the extension pipes.

[0036] When the tide is rising, seawater can enter the aquaculture device from the area where the extension pipe is located. Here, floating balls can be added at the top net to ensure that the net bulges and increase the internal space of the cylindrical structure. After the ebb tide, the seawater in the aquaculture device is higher than that on the tidal flat. Under the action of the communicating vessel 3, when the second floating ball 36 drops to the threshold value, the first floating ball floats up so that the sealing cover 32 blocks the water inlet of the drainage channel 31.

[0037] An intelligent monitoring device is provided on the aquaculture device. It includes a camera, a sea condition detection device, etc. The above devices are connected to a handheld terminal, which can ensure that the aquaculture farmers can understand the situation of the aquaculture area in real time.

[0038] Although the present invention is illustrated and described by using specific embodiments and their alternative ways, it should be understood that various changes and modifications can be implemented as long as they do not deviate from the spirit of the present invention. Therefore, it should be understood that the present invention is not limited in any sense except by the limitations of the appended claims and their equivalent conditions.
