The mariculture organism multi-network co-harvesting device provided by the embodiment can be used for sampling fishes and shrimps which are cultured in different stages in the aquaculture net so as to check whether the fishes and the shrimps in the aquaculture process are healthy or not. In this embodiment, mount pad 1 is used for the deck fixed connection with the hull, the mounting hole has been seted up on mount pad 1, the accessible bolt is installed it on the deck, coupling mechanism is connected with mount pad 1, fixed pulley 14 rotates the one end that sets up at coupling mechanism, fixed pulley 14 extends to the outside of hull, stay cord 10 passes fixed pulley 14 and connects a plurality of sampling box 5, can drive each sampling box 5 through pulling stay cord 10 and shift up in step, and release stay cord 10, under the effect of balancing weight 503, can drive each sampling box 5 and sink into the aquatic, sample. The number of the balancing weights 503 is plural, not less than three, and the balancing weights are spliced and matched, the soft belt 502 is used for connecting the balancing weights 503 with the top opening of the body 501, the soft belt 502 can be made of rubber, plastic coated cloth and the like, bending of not less than 180 degrees, soft elasticity and no water leakage can be realized, and the soft belt 502 can be respectively connected with the body 501 and the balancing weights 503 in a gluing and screw mode. Under the action of the soft belt 502, the plurality of balancing weights 503 have a splicing state and an un-splicing state, before and during the process that the sampling box 5 sinks into water, the plurality of balancing weights 503 are in the un-splicing state, at this time, the soft belt 502 is turned over outwards, and the opening of the sampling box 5 is opened; when the pull rope 10 is pulled upwards to move the sampling box 5 upwards, the plurality of balancing weights 503 are in a splicing state, and at the moment, the opening of the sampling box 5 is shielded by the soft belt 502 and the balancing weights 503. The plurality of balancing weights 503 are arranged circumferentially and equidistantly with respect to the body 501, so that no matter the plurality of balancing weights 503 are in an un-spliced state or a spliced state, the gravity center of the sampling box 5 is unchanged and is always located on a vertical central line. The open-top of body 501 is the opening of sampling box 5 promptly, the open-top of body 501 is circular, the top surface area of a plurality of balancing weights 503 under the concatenation state also is circular, because the top surface area sum of a plurality of balancing weights 503 is less than the open area of body 501 under the concatenation state (the circular diameter of top surface of a plurality of balancing weights 503 is less than the circular diameter of body 501 opening promptly), make a plurality of balancing weights 503 and soft area 502 form a cone, sampling box 5 is from the opening of body 501 to the top surface of a plurality of balancing weights 503, its cross sectional area reduces gradually, but greatly reduced sampling box 5 is at the aquatic resistance of rebound. The working principle of the multi-network co-production device for marine farmed organisms provided by the invention is that firstly, the balancing weights 503 are in an un-spliced state, so that the opening of the sampling box 5 is opened, the self weight of the body 501 is light, the balancing weights 503 cannot be driven to be in a spliced state, then the pull rope 10 is loosened, under the action of the balancing weights 503, the body 501 is driven to move downwards and sink into seawater together until the body sinks into the net bottom of the aquaculture net, so that the bottom of the sampling box 5 is abutted against the aquaculture net, at the moment, the opening of the sampling box 5 is still opened, seawater is filled into the sampling box 5, fish or shrimps enter the sampling box 5 from the opening, after a period of time, the pull rope 10 is pulled upwards, at the moment, because the seawater is filled into the sampling box 5, the gravity is greatly increased, when the pull rope 10 is pulled upwards, each balancing weight 503 moves upwards until the splicing of each balancing weight 503 is completed, and then the balancing weights 503 drive the soft belt 502 to be pulled straight, and drive body 501 rebound, whole sampling box 5 is seted up rebound this moment, and the top surface area of sampling box 5 under the concatenation state is less to can increase speed, move up on the surface of water sampling box 5 with higher speed, thereby accomplish the sampling. In the prior art, because the culture box (equivalent to the sampling box 5 in the invention) is completely immersed in the sea, and the opening at the top of the culture box has a large diameter, when the culture box is pulled upwards, the culture box is subjected to a large resistance to water, and the pulling speed is higher, the resistance is higher, and when the speed is higher, the culture box is easy to pull upwards difficult and even rope-off, therefore, in the process of pulling the culture box upwards, the resistance of water can be better reduced only by being forced to be reduced to a lower pulling speed, the culture box is smoothly and safely pulled out of the water surface, obviously, the lower pulling speed can cause the culture box to be pulled upwards for a longer time, the physical consumption of operators is increased, and the fatigue state is easy to appear. According to the invention, the balancing weight 503 is designed to be spliced and movable, so that the purpose of reducing the area of the top surface of the sampling box 5 is realized, the resistance of water is reduced, the upward moving speed is increased, and the physical consumption is saved.

In the embodiment, by arranging the matching clump weights 503 in a splicing manner, the sum of the top surface areas of the clump weights 503 is smaller than the opening area of the body 501 in the splicing state, the opening of the body 501 is covered by the soft belt 502 and the clump weights 503 in the splicing state, so that the top surface area of the sampling box 5 is gradually reduced from the opening of the body 501 upwards, and the resistance can be greatly reduced when the sampling box 5 with the reduced top surface area moves upwards in water. And the physical consumption of operators is saved, and the defects in the prior art can be effectively overcome.

In this embodiment, when pulling up sampling box 5, because the opening of sampling box 5 is sheltered from by soft area 502 and balancing weight 503 and is covered for fish or shrimp in sampling box 5 are difficult for wandering out from sampling box 5, guarantee the quantity of sampling.

Utilize vertical rope 7 to make, when the pull-up stay cord 10, the bottom that vertical rope 7 can each oblique stay cord 6 all is close to the center of vertical rope 7 to make each balancing weight 503 be close to the center of vertical rope 7, so that balancing weight 503 gets into the concatenation state smoothly. Meanwhile, the stay cable 6 has a certain length, so that the soft belt 502 and the balancing weight 503 can be turned outwards until the outer side surface of the balancing weight 503 is attached to the outer side surface of the body 501.

Still further, the outer fixed surface of body 501 is provided with the stopper 504 with a plurality of balancing weights 503 one-to-one, stopper 504 passes through sticky mode fixed mounting on the outer surface of body 501, the lateral surface of stopper 504 be provided with balancing weights 503's lateral surface assorted recess, the bottom of recess is provided with the baffle, under the state of not splicing, the lateral surface of each balancing weight 503 is located the recess that corresponds respectively. The heights of the limiting blocks 504 are the same, when the balancing weights 503 are turned outwards until the outer side surfaces of the balancing weights 503 are respectively positioned in the corresponding grooves, and the balancing weights 503 are abutted against the top of the baffle plate, the heights of the balancing weights 503 are the same, so that the gravity center of the sampling box 5 can be ensured to smoothly fall on the vertical central line of the sampling box 5; the groove is used for limiting the balancing weight 503, so that the balancing weight 503 is prevented from swinging left and right to cause the gravity center of the sampling box 5 to swing, and the stability in the sampling process is ensured; and simultaneously, the sampling box 5 is always in the state that the opening is opened before entering the seawater.

Still further, do not guarantee that sampling box 5 sinks the in-process in the sea water, each balancing weight 503 can not appear rocking, balancing weight 503 has metal material to make, it has adsorption magnet (not shown in the figure) to embed in stopper 504, balancing weight 503 is connected with adsorption magnet adsorbs, utilize the adsorption affinity, can guarantee the steadiness of balancing weight 503, simultaneously, the adsorption affinity between each balancing weight 503 and the adsorption magnet is far less than the weight after sampling box 5 pours into the sea water, when guaranteeing to pull-up rope 10, balancing weight 503 can be in the concatenation state smoothly.

In this embodiment, the body 501 includes an upper accommodating body 50101, a middle accommodating body 50102 and a lower inserting body 50103 which are sequentially arranged, and the lower inserting body 50103, the middle accommodating body 50102 and the lower half portion of the upper accommodating body 50101 are formed into a cone shape together, so that in the process that the sampling box 5 moves into seawater under the action of the gravity of the balancing weight 503, the resistance of the seawater to the sampling box 5 can be effectively reduced, and the sampling box 5 can quickly fall into the bottom of the aquaculture net.

Further, the upper receiving body 50101 is made of a hard material which is not easily deformed. The upper housing 50101 serves to support the entire sampling chamber 5 and to fill the chamber of the upper housing 50101 with seawater and fish or shrimp when the sampling chamber 5 is filled with seawater.
