Description

Technical Field

[0001] The invention relates to a fish farming barrel auxiliary fish retrieval device and a use method thereof. Background Art

[0002] In the current fishery field, a fish farming model using a barrel has emerged. When using the barrel farming model, sewage discharge equipment is installed at the bottom of the breeding tank to recycle the residual bait and feces generated during the breeding process, so as to achieve zero discharge of breeding wastewater. The diameter of the existing barrels used for fish farming is generally about 3-4 meters, and the depth is generally about 1.5 meters, so the internal fish farming space is not small. When taking fish from the barrel, due to the special shape of the barrel, the existing traditional fishing nets can no longer be used in the barrel. Using a scoop net to directly catch fish in the barrel not only has low work efficiency, but also has high labor intensity. Summary of the invention

[0003] The object of the present invention is to provide an auxiliary fish taking device for a fish farming barrel and a method for using the same. The fish taking device can smoothly realize the work of taking fish in the barrel, which not only greatly improves the efficiency of taking fish in the barrel, but also reduces the labor intensity of manual fish taking.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a fish farming barrel auxiliary fish retrieval device, including a cylindrical fishing net, an upper line rope, a lower line rope and a rope-collecting counterweight block, the upper end and the lower end of the cylindrical fishing net are respectively provided with an upper opening and a lower opening, the upper line rope is arranged on the circumferential edge of the upper opening, the lower line rope is arranged on the circumferential edge of the lower opening, the rope-collecting counterweight block is arranged outside the edge of the lower opening, and the movable end of the lower line rope passes through the rope-collecting counterweight block, and a plurality of net sinkers are arranged on the circumferential edge of the lower opening.

[0005] Preferably, a plurality of pull rings are provided on the peripheral edge of the lower opening, and the lower line rope is looped inside the pull rings.

[0006] Furthermore, a hanging ring is provided on one side of the upper part of the rope collecting counterweight block, and the hanging ring is connected to the lower part of the cylindrical fishing net through a cable tie.

[0007] Furthermore, a plurality of buoys are arranged on the upper line rope.

[0008] Furthermore, the fish catching device also includes a net lowering auxiliary device, which includes an electric air pump and an annular air bag. The annular air bag is arranged on the inner side of the edge of the lower opening circle, and an air inlet pipe is arranged on the annular air bag. The air inlet pipe is connected to the electric air pump through a ventilation hose.

[0009] The present invention also provides a method for using the above-mentioned fish retrieval device to retrieve fish in a confinement barrel, comprising the following steps:

[0010] S1, moving the fish retrieval device to the side of the enclosure barrel where fish need to be retrieved;

[0011] S2, turning on the power of the electric air pump so that the annular air bag starts to be inflated. When the outer diameter of the annular air bag is slightly smaller than the inner diameter of the enclosure barrel, the power of the electric air pump is turned off, and the annular air bag is kept in a pressure-maintaining state;

[0012] S3, lift the lower end of the cylindrical fishing net, and place the annular inflatable bag on the upper side of the enclosure barrel;

[0013] S4, slowly release the cylindrical fishing net, and the lower end of the cylindrical fishing net and the annular inflatable bag slowly sink to the bottom of the enclosure barrel under the action of the rope counterweight, the net sinker and the pull ring. During the sinking process of the cylindrical fishing net, the movable end of the lower line rope and the connection end of the ventilation hose and the electric air pump should always be located outside the upper part of the enclosure barrel;

[0014] S5. When the lower end of the cylindrical fishing net sinks to the bottom of the enclosure barrel, the upper opening of the cylindrical fishing net is turned outward and clamped on the upper edge of the enclosure barrel, and the upper line rope is fastened to the upper part of the enclosure barrel. At this time, it is necessary to ensure that the movable end of the lower line rope and the connection end of the ventilation hose and the electric air pump are still outside the upper part of the enclosure barrel;

[0015] S6, disconnect the ventilation hose from the electric air pump to deflate the annular air bag; then, slowly pull the movable end of the lower line rope to slowly shrink the lower line rope, and the slow shrinkage of the lower line rope causes the lower opening of the cylindrical fishing net to begin to shrink. When the lower line rope is fully tightened and shrunk, the lower opening of the cylindrical fishing net is in a closed state, so that all the fish in the confinement barrel are located in the cylindrical fishing net;

[0016] S7, continue to pull the lower line rope to lift the lower end of the cylindrical fishing net. As the lower end of the cylindrical fishing net is continuously lifted, the fish in the cylindrical fishing net are continuously gathered to the upper part of the cylindrical fishing net. When the bottom of the cylindrical fishing net is lifted to a certain extent, the fish in the cylindrical fishing net are driven into a corner of the cylindrical fishing net. At this time, the scoop net can be used to smoothly carry out the fish retrieval operation;

[0017] S8. After all the fish in the cylindrical fishing net are taken out, the upper line rope is untied from the upper part of the pen barrel, and then the cylindrical fishing net is taken out from the pen barrel, thereby completing the process of taking out fish from the pen barrel.

[0018] The beneficial effects of the present invention are as follows: the present invention has a simple structure and is easy to use and operate; in actual use, the upper line rope can be used to ensure that the upper end of the cylindrical fishing net is firmly fixed on the upper opening of the enclosure barrel, thereby facilitating smooth fish retrieval, and the buoy arranged on the upper line rope can ensure that even if the upper opening of the cylindrical fishing net falls off the enclosure barrel, it will not fall into the lower part of the enclosure barrel, thereby ensuring the progress of the fish retrieval; the fixing effect of the rope-collecting and breeding block can be used to achieve smooth contraction of the lower opening of the cylindrical fishing net when the lower line rope is pulled, thereby making all the fish in the enclosure barrel gathered in the cylindrical fishing net, providing convenience for the next step of using a scoop net for centralized fishing; the elastic expansion function of the annular inflatable bag can be used to make the lower opening edge of the cylindrical fishing net close to the side wall of the enclosure barrel and smoothly slide down the bottom of the enclosure barrel when the net is lowered in the enclosure barrel, thereby ensuring that the fish in the enclosure barrel will not remain between the cylindrical fishing net and the side wall of the enclosure barrel, thereby improving the success rate of taking all the fish in the subsequent enclosure barrel at one time.

DETAILED DESCRIPTION

[0028] The following will be combined with specific embodiments and attached Figure 1-7 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the present invention, rather than all the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0029] The present invention provides a fish farming barrel auxiliary fish taking device (such as Figure 1 As shown in the figure, the cylindrical fishing net 1 comprises an upper line rope 2, a lower line rope 3 and a rope-collecting counterweight 4. The upper end and the lower end of the cylindrical fishing net 1 are respectively provided with an upper opening 11 and a lower opening 12. The upper line rope 2 is arranged on the circumferential edge of the upper opening 11. Specifically, the upper line rope 2 can be inserted into the fishing mesh of the upper opening 11. In actual application, when the cylindrical fishing net 1 is used to take fish from the enclosure barrel, the upper line rope 2 is used to fix the upper opening 11 of the cylindrical fishing net 1 to the upper edge of the enclosure barrel 101. In order to prevent the upper line rope 2 from falling off from the enclosure barrel 101 and causing the cylindrical fishing net 1 to sink to the bottom of the enclosure barrel 101, a plurality of buoys 21 are arranged on the upper line rope 2, thereby ensuring that the upper opening 11 of the cylindrical fishing net 1 is always located at the upper part of the enclosure barrel 101, the lower line rope 3 is arranged on the peripheral edge of the lower opening 12, the rope collecting counterweight 4 is arranged outside the edge of the lower opening 12, and the movable end of the lower line rope 3 passes through the rope collecting counterweight 4. In the embodiment, when the two movable ends of the lower rope 3 are pulled, in order to facilitate the contraction of the lower opening 12, a plurality of pull rings 13 are arranged on the peripheral edge of the lower opening 12, and the lower rope 3 is sleeved in the pull rings 13. The lower rope 3 can slide freely in the pull rings 13, which is conducive to the smooth contraction and sealing of the lower opening 12 through the contraction of the lower rope 3. By utilizing the counterweight effect of the rope collecting and breeding block 4, when the two movable ends of the lower rope 3 are pulled, it can be ensured that the lower rope 3 is relative to the pull ring 13. The relative sliding and contracting movement can then smoothly realize the contraction of the lower opening 12. In this specific embodiment, in order to facilitate the connection between the rope collecting and breeding block 4 and the outer side of the lower opening 12, a hanging ring 41 is provided on one side of the upper part of the rope collecting and breeding block 4. The hanging ring 41 is connected to the lower part of the cylindrical fishing net 1 through a cable tie 42. A plurality of net sinkers 14 are provided on the circumferential edge of the lower opening 12. The gravity of the net sinkers 14 is utilized to facilitate the lower opening 12 to sink smoothly to the bottom of the enclosure barrel 101.

[0030] When the cylindrical fishing net 1 is put into the enclosure barrel 101, in order to facilitate the lower opening 12 to sink along the inner wall of the circumference of the enclosure barrel 101 so that all the fish in the enclosure barrel 101 are enclosed in the cylindrical fishing net 1, a net lowering auxiliary device is provided in the fish retrieval device, and the net lowering auxiliary device includes an electric air pump 52 and an annular air bag 51. The annular air bag 51 is provided on the inner side of the circumference edge of the lower opening 12. Specifically, the annular air bag 51 can be tied and fixed on the inner side of the lower opening 12 with a cable tie, and an air inlet pipe 511 is provided on the annular air bag 51. The air inlet pipe 511 is connected to the electric air pump 52 through a ventilation hose 53. When the net is lowered on the enclosure barrel 101, the electric air pump 52 is first used to blow up the annular air bag 51 to expand the annular air bag 51. When the outer diameter of the annular air bag 51 is slightly smaller than the inner diameter of the enclosure barrel 101, the inflation of the annular air bag 51 is stopped, and then the annular air bag 51 and the lower opening 12 are slowly placed into the opening of the enclosure barrel 101, and then the upper part of the cylindrical fishing net 1 is slowly released, so that the cylindrical fishing net 1 can be placed in the enclosure barrel 101.

[0031] The present invention also provides a method for using the above-mentioned fish catching device to catch fish, comprising the following steps:

[0032] S1, moving the fish retrieval device to the side of the enclosure barrel 101 where fish need to be retrieved;

[0033] S2, turning on the power of the electric air pump 52, so that the annular air bag 51 starts to be inflated. When the outer diameter of the annular air bag 51 is slightly smaller than the inner diameter of the enclosure barrel 101, the power of the electric air pump 52 is turned off, and the annular air bag 51 is kept in a pressure-maintaining state;

[0034] S3, lift the lower end of the cylindrical fishing net 1, and place the annular inflatable bag 51 on the upper side of the enclosure barrel 101;

[0035] S4, slowly release the cylindrical fishing net 1, the lower end of the cylindrical fishing net 1 and the annular inflatable bag 51 slowly sink to the bottom of the enclosure barrel 101 under the action of the gravity of the rope counterweight 4, the net sinker 14 and the pull ring 13. During the sinking process of the cylindrical fishing net 1, the movable end of the lower line rope 3 and the connection end of the ventilation hose 53 and the electric air pump 52 should always be located on the upper outer side of the enclosure barrel 101;

[0036] S5. When the lower end of the cylindrical fishing net 1 sinks into the bottom of the enclosure barrel 101, the upper opening 11 of the cylindrical fishing net 1 is turned outward and clamped on the upper edge of the enclosure barrel 101, and the upper line rope 2 is fastened to the upper part of the enclosure barrel 101. At this time, it is necessary to ensure that the movable end of the lower line rope 3 and the connection end of the ventilation hose 53 and the electric air pump 52 are still on the upper outer side of the enclosure barrel 101;

[0037] S6, disconnect the ventilation hose 53 from the electric air pump 52 to deflate the annular air bag 51; then, slowly pull the movable end of the lower line rope 3 to slowly shrink the lower line rope 3, and the slow shrinkage of the lower line rope 3 causes the lower opening 12 of the cylindrical fishing net 1 to begin to shrink. When the lower line rope 3 is fully tightened and shrunk, the lower opening 12 of the cylindrical fishing net 1 is in a closed state, so that all the fish in the confinement barrel 101 are located in the cylindrical fishing net 1;

[0038] S7, continue to pull the lower line 3, so as to realize the lifting of the lower end of the cylindrical fishing net 1. As the lower end of the cylindrical fishing net 1 is continuously lifted, the fish in the cylindrical fishing net 1 are continuously gathered to the upper part of the cylindrical fishing net 1. When the bottom of the cylindrical fishing net 1 is lifted to a certain extent, the fish in the cylindrical fishing net 1 are driven into a corner of the cylindrical fishing net 1. At this time, the scoop net can be used to smoothly carry out the fish retrieval operation;

[0039] S8. After all the fish in the cylindrical fishing net 1 are taken out, the upper line rope 2 is untied from the upper part of the pen barrel 101, and then the cylindrical fishing net 1 is taken out from the pen barrel 101, thereby completing the process of taking out fish from the pen barrel 101.
