chinese patent publication No. CN103461290A, published as 12 and 25 in 2013, discloses a shellfish harvester which uses a water-absorbing shellfish-taking method to dig out shellfish from the sea bottom and suck the shellfish into a ship from the sea bottom, and also absorbs a large amount of water, resulting in high energy consumption.
Chinese patent publication No. CN106719492B discloses a "double-ship continuous operation type deep sea shellfish harvesting system and method" for harvesting submerged shellfish on the seabed. The device also adopts a water absorption shellfish taking method, and absorbs a large amount of water while sucking shellfish fished into the net into the ship, thus causing larger energy consumption; meanwhile, the bottom trawl net slides from the seabed and sweeps the organisms passing through the bottom trawl net into the net, so that the ecological damage to the seabed is large.
In summary, the problems of the existing device for transporting the benthic shellfish are as follows:
1) After the shellfish is excavated and collected underwater, the shellfish is taken by absorbing water in the whole course, which results in large energy consumption, and the whole course means that the whole depth from the sea bottom to the sea surface absorbs water, so that the water consumption is large;
2) After the shellfish is excavated and collected underwater, extra towropes and winches are used as power mechanisms to lift the container for containing the shellfish underwater, so that the requirement on ship collecting equipment is high, and the operation is complex.
3) The bottom trawl destroys the seabed ecology and is forbidden.

Detailed Description
The invention is further described with reference to the following figures and specific examples.
With reference to fig. 1 and 2, fig. 1 shows an air-floating ocean-bottom shellfish transporter, and fig. 2 shows a side view of the air-floating ocean-bottom shellfish transporter.
Firstly, the embodiment focuses on the innovative means of the process of upward transportation and collection of shellfish after the shellfish is collected in a container on the seabed, and the shellfish is placed in the seabed for excavation, which belongs to the prior art, and the detailed description thereof is omitted. For example, chinese patent document with publication number CN201360480Y, publication number 12/16/2019, discloses an "automatic shellfish product harvesting boat" for harvesting seabed buried shellfish. The device adopts a hopper to dig the shellfish at the seabed, and the harvesting mode can be applied to the embodiment.
After completing the shellfish excavation and collecting in the container at the sea bottom (the shellfish collector 4 in this embodiment), the shellfish collector 4 needs to be lifted from the sea bottom, and this embodiment focuses on how this is done.
Referring to fig. 1-2, both ends of a shaft 3 are provided with coupling holes 2. After the guide cable penetrates through the connecting hole 2, the guide cable extends to the position above the unmanned boat, and the guide cable is not shown in the attached drawings.
Wherein the air pump 5 is fixedly arranged on the unmanned boat 1, and the collecting and transporting device can be hung on the seabed of the set sea area by a crane on the boat. It should be noted that the sea area is generally offshore, and is in the range of hundreds to thousands of meters from the shore (depending on the slope of the shore), and the depth of the sea water is generally within 10 meters.
The guide cable penetrates through the connecting hole 2 and then is fixed on a fixed object (such as a rack) at the seabed, and the unmanned boat at the other end is connected; the connecting hole 2 is fixed at one end of the shaft 3, the other end of the shaft 3 is connected with the shell collector 4, and the shell collector 4 can rotate around the shaft 3; the head end of the shell collector 4 is provided with an inlet, and the tail end of the shell collector is provided with a sealing plate; the first 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 onboard air pump through pipelines; through adjusting the gas volume in two gasbags, can change the contained angle of collection shellfish ware 4 and seabed, realize the heaving of collection shellfish ware 4 simultaneously, wherein first gasbag 6 is great, is mainly responsible for the heaving of collection shellfish ware 4, and tail gas bag 7 is less, is mainly responsible for adjusting the angle gesture of collection shellfish ware 4.
Wherein the connection hole 2 may be rigid or flexible, wherein flexibility is preferred because the guide cable is not easily worn.
Referring to fig. 4, fig. 4 illustrates the position change of the scallop collector, wherein (a) represents the collection site with the scallop collector on the seafloor, (b) represents the scallop collector rotating counterclockwise and beginning to lift upward, and (c) represents the scallop collector flipping the opening upward counterclockwise and continuing to lift upward.
When the shellfish collector 4 rises to the sea surface, the unmanned boat is remotely controlled to start, the shellfish collector 4 is pulled to the side of the mother ship, and the built-in net is taken out together with the shellfish in the shellfish collector 4 or the shellfish is sucked out by adopting an additional pump. The collecting and transporting device is arranged on a harvesting ship (mother ship) and can be hoisted into the sea by a crane on the harvesting ship.
In this embodiment, the shell collector 4 is water permeable and can be fitted with a flexible/rigid mesh inside.
In this embodiment, a pressure sensor is disposed at the closing plate of the shellfish collecting device 4, and the pressure sensor monitors the pressure of the shellfish received by the closing plate, and sends an actuating signal to the console when the pressure reaches a threshold value.
During operation, the ship crane puts the gathering device into the sea, the unmanned boat 1 moves forwards, drags the gathering device to move forwards, and then the operation is carried out according to the following steps:
s1, starting a pulse water sprayer, flushing sediment at the sea bottom by a sprayed water column, and simultaneously flushing shellfish, wherein the flushed shellfish falls into a shellfish collector 4 under the action of water flow and a part of the water column; (this step can also be replaced by a mechanical excavation and recovery mode);
s2, after the shells in the shell collector 4 accumulate to a certain weight, triggering a pressure sensor arranged in the shell collector 4, sending a signal to a control console by the pressure sensor, stopping the unmanned boat 1, inflating the two air bags by an air pump, floating the shell collector 4 upwards while rotating anticlockwise under the action of buoyancy of the two air bags by the shell collector 4 until the shells reach the sea surface, and enabling an opening of the shell collector 4 to be upward.
And S3, when the shell collector 4 reaches the sea surface, the unmanned ship 1 is remotely controlled to be started, and the shell collector 4 leans against the mother ship along with the inclination of the guide cable. At this time, the built-in net can be taken out from the shellfish collector together with the shellfish manually, or the shellfish can be sucked out from the shellfish collector by a pump.
S4, after the shells in the shell collector 4 are collected, (if the shells are taken out together with the built-in net, the built-in net needs to be installed again), the gas amount in the two air bags is reduced, so that the shell collector 4 can be ensured to form a proper included angle with the seabed through the two air bags while the shell collector 4 gradually sinks under the self weight of the shell collector, and then the unmanned boat 1 is started, so that the next collection is carried out.
While the preferred embodiments of the present invention have been described, those skilled in the art will appreciate that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
