[0002] In the process of crab farming, in addition to seedling quality, disease, and feed, cannibalism is the main reason for low yield. Cannibalism is their biological nature. During the farming cycle, fighting and cannibalism occur frequently. Newly molted swimming crabs have soft bodies, weak vitality, and their shells have not yet calcified. They have no defense against the aggressive behavior of other individuals and are very easy to be eaten by other individuals.

[0003] Crab molting protection device is an auxiliary device for isolating and protecting crabs during molting. However, the device is inconvenient in terms of space utilization and opening and closing control.

[0004] Therefore, a crab molting protection device is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a crab molting protection device to solve the problem mentioned in the background art that the crab molting protection device is not easy to control.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crab molting protection device, comprising a net cage, a control component, a feeding component, and a support component. The net cage has a partition plate installed inside, and an installation groove is provided at the center of the top of the net cage. A central tube is installed inside the installation groove. The control component is located on the outside of the net cage, the feeding component is located inside the central tube, and the support component is located at the bottom of the net cage.

[0007] As a further technical solution of this utility model, the control component includes an entry slot, an isolation door, a traction platform, a wire buckle, a traction rope, and a pull ring. The entry slot is disposed on the outer side wall of the cage, and an isolation door is movably installed on the outer side of the entry slot. The traction platform is fixed on the outer side wall of the isolation door.

[0008] As a further technical solution of this utility model, four sets of entry slots are provided on the outer side wall of the wire mesh cage, and the four sets of entry slots are distributed in a ring.

[0009] As a further technical solution of this utility model, a wire buckle is fixed on the outer wall of the central tube, a traction rope is provided on the inner side of the wire buckle, a pull ring is fixed at the top of the traction rope, and the bottom end of the traction rope is fixedly connected to the top of the traction platform.

[0010] As a further technical solution of this utility model, the feeding component includes an air pipe, a hose, a distribution plate, a through groove, and an air hole. The air pipe is installed at the center of the inside of the central tube. A hose is installed at the top of the air pipe. A distribution plate is fixed to the outer wall of the air pipe. A through groove is provided at the bottom of the outer wall of the central tube. An air hole is provided at the bottom of the outer wall of the air pipe.

[0011] As a further technical solution of this utility model, a plurality of air holes are provided at the bottom end of the outer wall of the trachea, and the plurality of air holes are distributed at equal intervals.

An isolation door is movably installed on the outside. It is pulled by a traction rope. When in use, the traction rope is moved up to pull the isolation door up and open the entry slot for the crab to enter. Conversely, the traction rope is released and the isolation door moves down to cover the entry slot, thereby closing the inner space and isolating and protecting the crab inside. This makes the crab molting protection device convenient to use.

[0015] By setting up a feeding component, the air tube and four sets of hoses work together to divide the internal space of the central tube into four channels, which correspond to the four spaces inside the net cage. In this way, the four spaces can be fed separately. When the food slides down the channel, it can enter the internal space of the net cage through the groove to feed the crabs. This realizes the auxiliary feeding function when using the crab molting protection device.

[0016] With the support components, four sets of raised platforms are fixed to the bottom of the net cage. The raised platforms have slots inside. When the counterweight bar is inserted into the slot, it can help increase the counterweight at the bottom of the net cage.

[0025] Please see Figure 1-6This utility model provides an embodiment of a crab molting protection device, comprising a net cage 1, a control component 5, a feeding component 6, and a support component 7. A partition plate 2 is installed inside the net cage 1. An installation groove 3 is provided at the center of the top of the net cage 1, and a central tube 4 is installed inside the installation groove 3. The control component 5 is located on the outside of the net cage 1, the feeding component 6 is located inside the central tube 4, and the support component 7 is located at the bottom of the net cage 1. The control component 5 includes an entry groove 501, an isolation door 502, a traction platform 503, a wire buckle 504, and a traction device. Rope 505 and pull ring 506, and entry groove 501 are set on the outer side wall of the net cage 1. There are four sets of entry grooves 501 on the outer side wall of the net cage 1. The four sets of entry grooves 501 are arranged in a ring. An isolation door 502 is movably installed on the outer side of the entry groove 501. A traction platform 503 is fixed on the outer side wall of the isolation door 502. A wire buckle 504 is fixed on the outer side wall of the central tube 4. A traction rope 505 is set on the inner side of the wire buckle 504. A pull ring 506 is fixed at the top of the traction rope 505. The bottom end of the traction rope 505 is fixedly connected to the top of the traction platform 503.

[0026] Specifically, such as Figure 1 and Figure 4 As shown, during use, the pull ring 506 can be used to pull up the traction rope 505. During this process, the bottom side of the traction rope 505 can be flipped upwards at the front isolation door 502, exposing the inner entry slot 501, which allows crabs to enter. Afterwards, the pull ring 506 is released, and the isolation door 502 can be lowered under the assistance of gravity to cover the outside of the air tube 601, blocking the entry slot 501 and isolating and protecting the crabs that have entered.

[0027] The feeding component 6 includes an air pipe 601, a hose 602, a distribution plate 603, a through groove 604, and air holes 605. The air pipe 601 is installed at the center of the central tube 4. The hose 602 is installed at the top of the air pipe 601. The distribution plate 603 is fixed to the outer wall of the air pipe 601. The through groove 604 is provided at the bottom of the outer wall of the central tube 4. The air hole 605 is provided at the bottom of the outer wall of the air pipe 601. Several air holes 605 are provided at the bottom of the outer wall of the air pipe 601, and the several air holes 605 are distributed at equal intervals.

[0028] Specifically, such as Figure 1 and Figure 5 As shown, during use, the feed distribution plate 603 divides the interior of the central tube 4 into four sets of channels. When the feed enters through the four sets of channels, it can enter the interior of the net cage 1 through the through groove 604 to assist in feeding the crabs inside the net cage 1. An air pipe 601 is installed in the center, and the top hose 602 can be connected to an oxygen generator. After oxygen is introduced into the air pipe 601, it can be sent into the interior of the net cage 1 through the air hole 605 on the bottom side to improve the environment inside the net cage 1.

[0029] The support component 7 includes a platform 701, a slot 702, a counterweight 703, and a protruding ring 704. The platform 701 is fixed to the bottom of the wire mesh cage 1. There are four sets of platforms 701 fixed to the bottom of the wire mesh cage 1. The four sets of platforms 701 are symmetrically distributed. The platform 701 is provided with a slot 702 inside. The counterweight 703 is inserted into the slot 702. The outer wall of the counterweight 703 is fixed with a protruding ring 704.

[0030] Specifically, such as Figure 1 and Figure 6 As shown, during use, four sets of lifting platforms 701 are fixed at the bottom of the net cage 1 to help raise the net cage 1 for use. A counterweight 703 can be inserted into the slot 702 inside the lifting platform 701. With the help of the counterweight 703, the bottom side of the net cage 1 can be increased, which helps the net cage 1 to be placed stably for use and prevents it from moving with the water flow.

[0031] Working principle: In use, the net cage 1 is placed in water, with the top opening of the central tube 4 protruding above the liquid surface. Four sets of support platforms 701 are fixed at the bottom of the net cage 1 to help elevate it. Counterweights 703 can be inserted into the slots 702 inside the support platforms 701, increasing the weight on the bottom of the net cage 1 and helping to stabilize it and prevent it from moving with the water flow. Four sets of inlet slots 501 are symmetrically distributed on the outer surface of the net cage 1, corresponding to the four spaces inside the net cage 1 divided by four sets of partition plates 2. An isolation door 502 is movably installed on the outside, and is pulled by a traction rope 505. In use, moving the traction rope 505 upwards will pull the isolation door 502 upwards and open it. The crabs enter through the trough 501. Conversely, by releasing the traction rope 505, the isolation door 502 moves down and covers the trough 501, thus closing the inner space and isolating and protecting the crabs inside. The central tube 4 is located at the center of the four spaces. The air pipe 601 works with the four sets of hoses 602 to divide the internal space of the central tube 4 into four channels, corresponding to the four spaces inside the net cage 1. When food slides down the channels, it can enter the internal space of the net cage 1 through the through trough 604 for feeding the crabs. The air pipe 601 at the center can be connected to an oxygen generator through the hose 602 at the top. After oxygen is introduced into the air pipe 601, it can be sent into the inside of the net cage 1 through the air hole 605 on the bottom side to improve the internal environment of the net cage 1.
