Description

Technical Field

[0001] This utility model relates to the field of fish farming, specifically a fish catching device for experimental water tank fish farming. Background Technology

[0002] Experimental fish farming refers to fish farming activities conducted under specific experimental conditions for scientific research, teaching, and variety improvement. The materials of the tanks are diverse, such as glass, plastic, and metal. The appropriate type should be selected according to the scale of farming and the species. The tanks should be equipped with filtration systems, aeration equipment, heating or cooling devices, etc., to maintain a good aquatic environment. Experimental fish farming is of great significance in scientific research, production practice, and talent training, and provides strong support for the sustainable development of fisheries and technological innovation.

[0003] Existing experimental fish are raised in multiple tanks. Traditional methods of catching these fish involve using long-pole nets. However, due to the large number of fish and their high activity levels, the fish dart around, making them difficult to catch and easily leading to mistakes or missing fish altogether. Therefore, a fish catching device for experimental tank fish farming is proposed to solve these problems. Utility Model Content

[0026] 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.

[0027] In the embodiments, by Figure 1-4 Presented is a fish catching device for experimental fish tank farming. This utility model includes a support frame 1, a water tank 2 fixedly connected inside the support frame 1, four hydraulic push rods 3 fixedly connected to the outside of the support frame 1, a fixing plate 4 fixedly connected to the top of each of the four hydraulic push rods 3, a limit rod 5 fixedly connected to the top of each of the four fixing plates 4, two catching frames 6 arranged symmetrically on the left and right sides inside the water tank 2, a catching net being set inside each of the two catching frames 6, two limit plates 7 fixedly connected to the outside of each of the two catching frames 6 and located outside the four limit rods 5 respectively, and threaded sleeves 8 threadedly connected to the outside of each of the four limit rods 5 and located above the four limit plates 7 respectively.

[0028] Among them, the four hydraulic push rods 3 are symmetrically distributed in pairs, front and back, left and right, and the four limiting plates 7 are located on the front and back sides of the two salvage frames 6 respectively. The four limiting rods 5 all pass through and extend to the outside of the four limiting plates 7 respectively.

[0029] In this embodiment, during actual use, the four fixed plates 4 can provide support for the four limiting plates 7, while the limiting rods 5 restrict the support direction of the limiting plates 7 and the salvage frame 6, preventing them from shifting or shaking, and stabilizing the placement of the salvage frame 6.

[0030] Among them, the outer sides of the two salvage frames 6 are fixedly connected with connecting plates 9, and the inner threads of the two connecting plates 9 are connected with bolt knobs 10.

[0031] In this embodiment, during actual use, the two salvage frames 6 are raised by the front and rear hydraulic push rods 3 respectively. The synchronous start of the hydraulic push rods 3 enables them to move and rise simultaneously. With the connection plate 9 fixed by the bolt knob 10, the stability of the two salvage frames 6 is enhanced, making their synchronous rise and fall smoother. Removing the bolt knob 10 allows them to rise and fall independently without affecting each other.

[0032] The two salvage frames 6 are provided with clearance grooves on opposite sides, and the opening and closing door frame 11 is rotatably connected inside the two clearance grooves.

[0033] In this embodiment, during actual use, the clearance slot enables internal communication between the two retrieval frames 6, allowing the fish to have more space to move around. The opening and closing door frame 11 can rotate relative to the retrieval frame 6 via a hinge, and can also be closed via a locking block to isolate the interior of the two retrieval frames 6. After isolation, the retrieval frames 6 can be used to individually remove and distinguish the fish that need to be tested.

[0034] Each of the four limiting plates 7 has a handle 12 fixedly connected to its top, and foot pedals 13 are provided on both the left and right sides of the support frame 1.

[0035] In this embodiment, during actual use, after removing the threaded sleeve 8, the salvage frame 6 can be lifted and removed by the handle 12, and the foot pedal 13 provides a higher range of motion, making it easier to remove the salvage frame 6.

[0036] Both salvage frames 6 are rectangular and fit against the inner wall of the water tank 2, and the support frame 1 has a storage slot 14 inside.

[0037] In this embodiment, both the salvage frame 6 and the water tank 2 are rectangular in actual use, which reduces the gap between the salvage frame 6 and the water tank 2, allowing the salvage frame 6 to salvage all the fish in the water tank 2. The storage tank 14 can store the removed threaded sleeve 8 and bolt knob 10 to prevent them from falling into the water tank 2.

[0038] Working principle:

[0039] First, two retrieval frames 6 are arranged inside the water tank 2. The retrieval frames 6 provide support for the arrangement of the retrieval net. The switch door frames 11 inside the two retrieval frames 6 are normally open, allowing the fish to swim normally in the water tank 2. The bolt knobs 10 also lock and fix the two connecting plates 9. When retrievaling fish, four hydraulic push rods 3 can be activated simultaneously. At this time, the two retrieval frames 6 will be raised. Under the action of the retrieval net, the fish will be divided into the left and right retrieval frames 6. The switch door frames 11 of the two retrieval frames 6 are closed. When the fish to be used for the experiment is in a certain retrieval frame 6, the bolt knobs 10 can be removed, and the retrieval frame 6 can be lowered by the corresponding hydraulic push rods 3, so that the fish can return to the water tank 2 to maintain their activity. The experimental fish in the retrieval frame 6 can be directly taken out with the retrieval net, or the threaded sleeve 8 can be removed, and the entire retrieval frame 6 can be raised and removed from the limit rod 5 by the handle 12, so as to facilitate the slow selection of experimental fish.
