Where buried shellfish harvesting for the seafloor generally refers to offshore areas, ranging from hundreds to thousands of meters from shore (differentiated by the gradient of the coast), such use environments, the prior art is for example:
the chinese patent literature with publication No. CN103461290a, publication No. 2013, 12, 25, discloses a shellfish harvester which adopts a water-absorbing shellfish-taking method, and absorbs a large amount of water while digging shellfish from the seabed and sucking the shellfish into a ship from the seabed, resulting in a large energy consumption.
The Chinese patent document with publication number of CN106719492B discloses a double-boat continuous operation type deep sea shellfish collecting and catching system and a collecting and catching method thereof, which are used for collecting seafloor buried shellfish. The device also adopts a water-absorbing shellfish taking method, and absorbs a large amount of water while sucking the shellfish which is fished into the net into the ship, so that the energy consumption is larger; meanwhile, the bottom trawl slides over the seabed, and the organisms passing through the bottom trawl are scanned into the net, so that the ecological damage to the seabed is large.
To sum up, the existing seafloor buried shellfish shipping devices have the following problems:
1) After the shellfish is excavated and collected underwater, the shellfish is extracted by adopting the whole process of water absorption, so that the energy consumption is high, and the whole process refers to the water absorption from the seabed to the whole depth of the sea surface, so that the water consumption is high;
2) After the shellfish is excavated and collected under water, an additional towing rope and a winch are adopted as a power mechanism to lift a container for holding the shellfish under water, so that the requirements on the equipment of a harvesting ship are high, and the operation is complex.
3) The trawl damages the seabed ecology and is forbidden.

Detailed Description
The invention will be further described with reference to the drawings and specific examples.
Referring to fig. 1 and 2, fig. 1 shows an air-floating seafloor shellfish carrier, and fig. 2 shows a side view of the air-floating seafloor shellfish carrier.
First, this embodiment focuses on innovative means made in the process of upward transportation and collection after shellfish are collected in a container on the seafloor, and the process of digging shellfish on the seafloor belongs to the prior art, and this embodiment will not be described in detail. For example, chinese patent document publication No. CN201360480Y, publication No. 2019, 12, 16, discloses an "automatic shellfish product harvesting boat" for harvesting seafloor buried shellfish. The device adopts the hopper to excavate shellfish at the seabed, and the harvesting mode can be applied to the embodiment.
After the shellfish is excavated and collected in the container on the sea floor (the shellfish collector 4 in this embodiment), the shellfish collector 4 needs to be lifted up from the sea floor, and this embodiment focuses on how this is achieved.
Referring to fig. 1-2, the shaft 3 is provided at both ends with connection holes 2. After the guide cable passes through the connecting hole 2, the guide cable is extended above the unmanned ship, and the guide cable is not shown in the drawing.
Wherein the air pump 5 is fixedly arranged on the unmanned ship 1, and the gathering device can be hung by a crane on the ship to place the seabed in a set sea area. The sea area is usually offshore, and the sea depth is usually within 10 meters in the range of several hundred to several kilometers from the coast (depending on the coast gradient).
The guide cable passes through the connecting hole 2 and is fixed on a fixed object (such as a rack) on the sea bottom, and the other end of the guide cable is connected with the unmanned ship; the connecting hole 2 is fixed at one end of the shaft 3, the other end of the shaft 3 is connected with the shellfish collecting device 4, and the shellfish collecting device 4 can rotate around the shaft 3; the head end of the shell collector 4 is provided with an inlet, and the tail end is provided with a sealing plate; the head air bag 6 is arranged below the head part of the shell collector 4, the tail air bag 7 is arranged above the tail part of the shell collector 4, and the two air bags are connected with an air pump on a ship through a pipeline; through the gas quantity in two gasbags, can change the contained angle of album shellfish ware 4 and seabed, realize album shellfish ware 4 heave simultaneously, wherein first gasbag 6 is great, mainly is responsible for album shellfish ware 4 heave, and tail gas bag 7 is less, mainly is responsible for adjusting album shellfish ware 4's angle gesture.
Wherein the connection holes 2 may be rigid or flexible, wherein flexibility is preferred because the guide cables are not easily worn.
Referring to fig. 4, fig. 4 shows the change in position of the shellfish collector, wherein (a) indicates that the shellfish collector is located at the collection site on the seafloor, (b) indicates that the shellfish collector rotates counterclockwise and begins to lift upward, and (c) indicates that the shellfish collector turns over the opening counterclockwise and continues to lift upward.
When the shellfish collecting device 4 rises to the sea surface, the unmanned boat is started by remote control, the shellfish collecting device 4 is pulled to the side of the mother ship, the built-in net tool is taken out together with the shellfish in the shellfish collecting device 4, or the shellfish is sucked out by adopting another pump. The gathering and transporting device is arranged on a harvesting ship (mother ship) and can be hung into the sea by a crane on the harvesting ship.
In this embodiment, the hub 4 is water permeable and may have a flexible/rigid mesh mounted inside.
In this embodiment, a pressure sensor is arranged at the sealing plate of the shellfish collecting device 4, and monitors the pressure of shellfish received by the sealing plate, and when the pressure sensor reaches a threshold value, a starting signal is sent to the console.
During operation, the ship crane puts the gathering and transporting device into the sea, the unmanned ship 1 moves forward, drags the gathering and transporting device to move forward, and then the operation is carried out according to the following steps:
s1, starting a pulse water sprayer, and flushing out sediment on the seabed by using sprayed water columns, and flushing out the shellfish, wherein the flushed shellfish falls into a shellfish collecting device 4 under the action of water flow and partial water columns; (this step may also be replaced by mechanical digging and harvesting);
s2, after the shellfish in the shellfish collecting device 4 accumulates to a certain weight, triggering a pressure sensor arranged in the shellfish collecting device 4, sending a signal to an operating console by the sensor, stopping the unmanned ship 1, inflating the unmanned ship to two air bags by an air pump, and floating the shellfish collecting device 4 under the action of the buoyancy force of the two air bags, so that the shellfish collecting device 4 floats up while rotating anticlockwise until reaching the sea surface, and at the moment, the opening of the shellfish collecting device 4 faces upwards.
And S3, when the shellfish collecting device 4 reaches the sea surface, starting the unmanned ship 1 in a remote control mode, and leaning the shellfish collecting device 4 towards the side of the mother ship along with the inclination of the guide cable. At this time, the built-in net can be manually taken out of the shellfish collector together with shellfish, or the shellfish can be sucked out of the shellfish collector by a pump.
S4, after the shellfish in the shellfish collector 4 is collected, (if the shellfish collector is taken out together with the built-in net, the built-in net is required to be reinstalled), the gas quantity in the two air bags is reduced, so that the shellfish collector 4 can be ensured to form a proper included angle with the seabed through the two air bags while gradually sinking under the dead weight of the shellfish collector 4, and then the unmanned ship 1 is started, so that the next collection is performed.
The foregoing is a preferred embodiment of the present invention, and various changes and modifications may be made therein by those skilled in the art without departing from the general inventive concept, and such changes and modifications should be considered as falling within the scope of the claimed invention.
