Description

Technical Field

[0001] This utility model relates to the field of capture tool technology, specifically to a fish capture device for aquatic product sampling inspection. Background Technology

[0002] In aquaculture, it is necessary to regularly inspect the growth of aquatic products. Usually, a suitable proportion of aquatic products are selected for random inspection based on the quantity of aquatic products. In fish farming, because fish are very agile in the water, random inspection and capture are relatively difficult. Traditional methods use nets and seine nets for capture. On the one hand, this method is labor-intensive and requires the cooperation of many people. On the other hand, it is easy to cause stress to fish and cause fish injuries. Furthermore, the quantity captured is uncontrollable, which can lead to excessive sampling and waste of effort. In addition, this method is difficult to conduct targeted sampling and capture in some polyculture aquatic products. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides an aquatic product sampling and inspection device that enables precise and targeted fishing, avoiding the damage to fish that can easily occur with nets.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a fish capture device for aquatic product sampling inspection, which has the following beneficial effects:

[0016] 1. By setting up fishing components and a self-priming pump, when it is necessary to sample and catch fish, the fishing components are placed in the water through the main and auxiliary pipes. When fish enter the fishing components, the self-priming pump works to suck in water along with the fish. When the fish enter the suction pipe, the self-priming pump closes, and the fish are discharged through the opening and closing components, achieving a precise catching effect and avoiding damage to fish caused by large-scale net casting. In polyculture aquaculture, different species of fish live in water at different depths, and by placing the fishing components at different heights in the water, it is possible to target the catching of polyculture fish.

[0017] 2. By setting up opening and closing components and a grille, under normal conditions, the second coil spring uses its own elasticity to push the second pin to rotate, so that the second pin drives the sealing plate to seal with the bottom of the connecting cylinder through the support frame. This method can prevent air from entering the self-priming pump through the connecting cylinder, ensuring the airtightness of the self-priming pump. The grille can block fish when the self-priming pump is drawing water, preventing fish from being sucked into the self-priming pump, ensuring the stable operation of the self-priming pump while avoiding damage to the fish.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 A seafood sampling and catching device includes a main pipe 1, a secondary pipe 2 below the main pipe 1, a fishing component 4 at the bottom of the secondary pipe 2, a suction pipe 6 at the top of the main pipe 1, a self-priming pump 5 on the side of the suction pipe 6, a grid 11 inside the suction pipe 6 corresponding to the position of the self-priming pump 5, an opening and closing component 8 below the suction pipe 6, the opening and closing component 8 including a connecting cylinder 801 below the suction pipe 6, a fixing frame 805 on the outside of the connecting cylinder 801, a second pin 804 rotatably connected inside the fixing frame 805, a support frame 803 fixedly provided on the side of the second pin 804, a sealing plate 802 attached to the bottom of the connecting cylinder 801 on the support frame 803, the sealing plate 802 being downwardly split, and a second coil spring 806 connected to the fixing frame 805 on the side of the second pin 804.

[0026] In this invention, a fishing component 4 and a self-priming pump 5 are provided. When it is necessary to sample and catch fish, the fishing component 4 is placed in the water through the main pipe 1 and the auxiliary pipe 2. When fish enter the fishing component 4, the self-priming pump 5 works to suck in water along with the fish. When the fish enter the suction pipe 6, the self-priming pump 5 is turned off, and the fish are discharged through the opening and closing component 8, achieving the effect of precise catching and avoiding damage to fish caused by large-scale net casting. In polyculture aquaculture, different species of fish live in water at different depths, and by placing the fishing component 4 at different heights in the water, it can be used to target the fish in polyculture.

[0027] By setting the opening and closing component 8 and the grille 11, under normal conditions, the second coil spring 806 uses its own elasticity to push the second pin 804 to rotate, so that the second pin 804 drives the sealing plate 802 to seal with the bottom of the connecting cylinder 801 through the support frame 803. In this way, air can be prevented from entering the self-priming pump 5 through the connecting cylinder 801, ensuring the airtightness of the self-priming pump 5. The grille 11 can block fish when the self-priming pump 5 is sucking water, preventing fish from being sucked into the self-priming pump 5, ensuring the stable operation of the self-priming pump 5 while avoiding damage to the fish.

[0028] The support frame 803 is equipped with a solenoid valve 14, the side wall of the connecting cylinder 801 is provided with a corresponding insertion hole 15 for the solenoid valve 14, and the sealing plate 802 is provided with a micro switch 13 that is electrically connected to the solenoid valve 14.

[0029] By setting up solenoid valve 14 and micro switch 13, solenoid valve 14 will open when the sealing plate 802 is closed and connect to the plug hole 15, so that the sealing plate 802 is locked. This prevents the water flow from accidentally squeezing the sealing plate 802 open when the fish is not sucked in, which would cause the airtightness of the self-priming pump 5 to fail. When the fish is caught, the fish triggers micro switch 13, at which time solenoid valve 14 will close, so that the sealing plate 802 will open under the pressure of water flow and fish, achieving the purpose of automatic separation after fishing.

[0030] The sealing plate 802 is equipped with a buffer plate 12 to prevent aquatic products from being injured by collision;

[0031] By setting up a buffer plate 12, the fish can make flexible contact with the sealing plate 802, preventing the fish from colliding or being scratched when squeezing out the sealing plate 802, thus ensuring the health and safety of the fish and avoiding any impact on the sampling results.

[0032] The side wall of the suction pipe 6 is provided with a transparent window 7 for observing its internal condition;

[0033] By setting a transparent window 7, the situation inside the suction pipe 6 can be observed from the outside, and it can be observed whether the fish have been sucked in. This prevents small fish from failing to trigger the micro switch 13 and thus failing to be discharged in time. At the same time, it can be observed whether there are foreign objects blocking the grille 11, which would limit the operation of the self-priming pump 5.

[0034] A water filter rack 9 is provided below the connecting cylinder 801, and the water filter rack 9 is set at an angle.

[0035] By setting up a water filter rack 9, when the opening and closing component 8 is opened, the water will flow vertically downward through the water filter rack 9, while the fish are separated by the water filter rack 9 and flow into the collection device along the inclined water filter rack 9, avoiding the problem of secondary wading for fishing.

[0036] The fishing component 4 includes a fishing tube 401 connected to the secondary tube 2. The fishing tube 401 is provided with a soft baffle 402 that is set inward at an angle. The fishing tube 401 is also provided with a baiting tube 403 for storing bait.

[0037] By setting up a soft baffle 402 and a feeding tube 403, the soft baffle 402 is set in an inward angle, making it easier for fish to swim from the outside to the inside and more difficult to swim from the inside to the outside. This prevents fish from being disturbed and escaping from the fishing tube 401 when the self-priming pump 5 is started. The feeding tube 403 can store bait, which attracts fish into the fishing tube 401 and improves the efficiency of the catch.

[0038] The secondary pipe 2 is slidably connected to the inner wall of the main pipe 1. The secondary pipe 2 is provided with grooves 10 at equal intervals, and the main pipe 1 is provided with a locking component 3 that engages with the grooves 10.

[0039] The locking component 3 includes a connecting frame 301 mounted on the main pipe 1. A first pin 302 is rotatably mounted inside the connecting frame 301. A first coil spring 305 connected to the connecting frame 301 is sleeved on the first pin 302. A bending frame 303 is fixedly connected inside the first pin 302. A snap-fit ​​rod 304 connected to the groove 10 is provided at the front end of the bending frame 303. A rubber handle 306 is provided at the rear end of the bending frame 303.

[0040] By setting the groove 10 and the locking rod 304, the main pipe 1 and the secondary pipe 2 can be adjusted in length by means of sliding engagement, which is convenient for different water depth environments. The locking rod 304 can be locked with the groove 10 by the downward pressure of the first coil spring 305 and the bending frame 303, which can restrict the position of the secondary pipe 2. Furthermore, by pressing the rubber handle 306, the locking rod 304 can be quickly separated from the groove 10, which is convenient for the adjustment of the secondary pipe 2.

[0041] Working principle: The fishing component 4 is placed in the water at a suitable depth through the main pipe 1 and the auxiliary pipe 2, and suitable food is added to the feeding tube 403. When the fish squeeze through the soft baffle 402 and enter the fishing tube 401, the self-priming pump 5 works, drawing water and fish into the suction pipe 6. When the fish triggers the micro switch 13, the self-priming pump 5 stops working, and at the same time, the solenoid valve 14 separates from the plug hole 15. Under the force of the water flow and the weight of the fish, the sealing plate 802 is squeezed open, allowing the fish to fall onto the filter rack 9, thus achieving the purpose of random sampling and capture.

[0042] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
