Description

Technical Field

[0001] This utility model relates to the field of aquaculture facilities, specifically to a three-dimensional climbing and habitat device for raising juvenile crabs. Background Technology

[0002] During pond rearing, juvenile crabs often live suspended in the water layer. This suspension drives them to swim continuously to maintain their balance and position, resulting in a significant increase in energy consumption, which directly affects their growth and development efficiency and survival rate. To alleviate this problem, farmers usually need to put palm flakes, algae, and other attachment substrates into the water to provide the juveniles with an interface to climb and inhabit. By attaching to these substrate surfaces, the juvenile crabs can effectively reduce unnecessary swimming behavior, reduce energy consumption, and thus promote their normal development and improve the overall rearing effect.

[0003] In existing juvenile crab farming techniques, natural materials such as palm flakes and algae are often used as substrates. However, these materials are easily decomposed when submerged in water for a long time, which not only accelerates water quality deterioration but also consumes dissolved oxygen in the water, leading to a deterioration of the farming environment and causing mass mortality of juvenile crabs. In addition, the palm flakes or algae exposed on the water surface easily attract birds to forage. Juvenile crabs that live on them are easily preyed on by birds due to the lack of shelter, resulting in significant economic losses. Utility Model Content

[0004] The purpose of this utility model is to provide a three-dimensional climbing and habitat device for raising juvenile crabs, and to solve the following technical problems; In the process of raising juvenile crabs, natural materials such as palm flakes and algae are often used as attachment substrates. However, these materials are easily decomposed when submerged in water for a long time. This not only accelerates the deterioration of water quality but also consumes dissolved oxygen in the water, leading to the deterioration of the breeding environment and causing a large number of juvenile crabs to die.

[0005] The objective of this utility model can be achieved through the following technical solutions: A three-dimensional climbing and perching device for raising juvenile crabs includes a perching platform; a bird-repelling component is provided on the perching platform; the bird-repelling component includes a bird-repelling pole; climbing blocks are fixedly connected below the perching platform; multiple climbing blocks are provided and are equidistantly arranged below the perching platform; a protective frame is fixedly connected to the top of the perching platform.

[0006] Furthermore, a fixing plate is fixedly connected to the top of the protective frame; two fixing plates are provided and symmetrically arranged on the top of the protective frame; a rotating rod is rotatably connected to the top of the fixing plate; a bird-repelling block is fixedly connected to the top of the rotating rod; and a bird-repelling rod is fixedly connected to the bird-repelling block.

[0007] Furthermore, a drive rod is rotatably connected to the fixed plate; a drive motor is fixedly connected to the bottom of the fixed plate; the drive motor is connected to the drive rod; a drive gear is fixedly connected to the top of the drive rod; a driven gear is fixedly connected to the rotating rod; and the drive gear meshes with the driven gear.

[0008] Furthermore, a rotating wheel is fixedly connected to the bottom of the rotating rod below the fixed plate; a belt is sleeved on the rotating wheel.

[0009] Furthermore, the protective frame is provided with ventilation holes; there are multiple ventilation holes, which are equidistantly arranged on the protective frame.

[0010] Furthermore, a float is fixedly connected to the perch; two floats are provided and symmetrically arranged on both sides of the perch.

[0011] The beneficial effects of this utility model are: (1) By setting up a habitat in the breeding pond, the crab larvae can climb up using the climbing blocks at the bottom of the habitat. The surface of the climbing blocks is designed with a frosted texture to enhance the adhesion, making it easier for the crab larvae to climb to the top and fix themselves on the habitat to rest. This design effectively solves the problem that traditional natural materials such as palm leaves and algae are prone to decay. It not only prolongs the time that the crab larvae stay on the habitat, but also avoids the negative impact on the pond water quality, thus creating a healthier and more stable growth environment for the crab larvae.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 As shown, this utility model is a three-dimensional climbing and perching device for raising juvenile crabs, including a perching platform 1; a bird deterrent component is provided on the perching platform 1; the bird deterrent component includes a bird deterrent rod 6; climbing blocks 11 are fixedly connected below the perching platform 1; multiple climbing blocks 11 are provided and are arranged at equal intervals below the perching platform 1; a protective frame 3 is fixedly connected to the top of the perching platform 1. By placing the roosting platform 1 in the pond where juvenile crabs are raised, the juvenile crabs in the pond will climb upwards using the climbing blocks 11 at the bottom of the roosting platform 1. The climbing blocks 11 have a frosted texture, which allows the juvenile crabs in the pond to climb to the top of the climbing blocks 11 and fix themselves on the roosting platform 1. The juvenile crabs can then rest on the roosting platform 1, reducing their activity and energy consumption, thus allowing them to develop normally. The protective frame 3 around the roosting platform 1 prevents the juvenile crabs from running around randomly and also prevents birds from landing directly on the roosting platform 1 and preying on them. By setting up the roosting platform 1 and the climbing blocks 11, the problem of easy decay of traditional natural materials such as palm leaves and algae is effectively avoided. This not only allows the juvenile crabs to stay on the roosting platform 1 for a longer time, but also does not have an adverse effect on the water quality of the cultivation pond, thus creating a better living environment for the juvenile crabs.

[0017] Please refer to the attached image. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, specifically, a fixed plate 4 is fixedly connected to the top of the protective frame 3; there are two fixed plates 4, which are symmetrically arranged on the top of the protective frame 3; a rotating rod 8 is rotatably connected to the top of the fixed plate 4; a bird-repelling block 5 is fixedly connected to the top of the rotating rod 8; a bird-repelling pole 6 is fixedly connected to the bird-repelling block 5; when working, the rotating rod 8 on the top of the fixed plate 4 is rotated, and the rotating rod 8 will drive the bird-repelling block 5 and the bird-repelling pole 6 to rotate. This is designed to prevent the device suspended in the pond from attracting birds to stay and thus prey on the juvenile crabs resting on the perch 1.
