Description

[0002] Cage aquaculture is a common form of aquaculture in lakes and reservoirs that involves high-density stocking in a local area. It has the characteristics of low input and high output, and can effectively improve the fishery production efficiency of lakes and reservoirs.

[0003] However, the artificial feeding based on experience used in the breeding process is labor-intensive and highly random, and often results in waste of feed and low feed utilization.

A floating chamber 1 is suspended on the outer side of the two opposite upper transverse tubes 2 as a buoyancy supply configuration.

[0040] In the collection system, an ear plate is provided on the top of the upper main connector 3, a transmission gear shaft 16 is installed on the ear plate, gears for transmission are provided at both ends of the transmission gear shaft 16, four ear plates are provided below the frame structure, two transmission rollers are respectively installed on the four ear plates through bearings, the two transmission rollers are respectively an active collection roller 17 and a driven collection roller 20, the active collection roller 17 and the driven collection roller 20 are respectively arranged in parallel at the same height, a roller gear 18 is provided at the outer end of the active collection roller 17, the roller gear 18 and the gear at the end of the transmission gear shaft 16 realize power transmission through the collection system crawler 19.

[0041] The operation process of the collection system is as follows: when the drive motor 14 is used as the driving mechanism of the collection system, the drive motor 14 drives the transmission gear shaft 16 to rotate through the drive gear 15, and the gears at both ends of the transmission gear shaft 16 are used as the power input end and the power output end to drive the collection system crawler 19 to rotate.

In this embodiment, the top rotation range of the collection net 21 moves from left to right, so that the collected materials on the top of the collection net 21 can be transported to the collection trough 28 one by one.

[0042] Example 2

[0043] Based on the low-pollution ecological cage device in the above-mentioned embodiment 1, this embodiment adds a transportation system.

[0044] like Figure 1-Figure 5As shown, the transportation system outside the frame structure includes a collecting gear shaft 22, a transmission gear, a shaft end gear, a collecting gear and a collecting crawler, wherein the transmission gear is mounted outside the collecting gear shaft 22, there are two shaft end gears and are respectively installed at both ends of the collecting gear shaft 22, the collecting gear shaft 22 is installed on the upper side of the frame structure, there are two collecting gears and are respectively installed on the lower side of the frame structure, there are two collecting crawlers, and the collecting crawlers are wrapped around the outside of the shaft end gear and the collecting gear, and the two ends of the collecting trough 28 are hinged to the two collecting crawlers; the collecting trough 28 can be driven by the collecting crawler to move from the end of the rotating section of the collecting net 21 to the top of the frame structure.

[0045] In this embodiment, the upper main connector 3 and the upper secondary connector 4 have a lug structure extending laterally outward on the side, and the collection gear shaft 22 is installed on the lug structure through a bearing, and the left upper driven collection gear and the right upper driven collection gear 25 are installed on the left and right ends of the collection gear shaft 22. At the end position of the upper rotation direction of the collection net 21, the lower main connector 7 has a lug extending laterally, and the left driven collection gear 23 and the right lower driven collection gear 26 are installed on the lug, respectively. The gears at both ends of the collection gear shaft 22 are respectively connected to the left driven collection gear 23 and the right lower driven collection gear 26 through two right collection crawlers 27.

[0046] The operation process of the transportation system is as follows: when the driving motor 14 is used as the power mechanism of the transportation system, the driving gear 15 at the output end of the driving motor 14 meshes with the gear on the collecting gear shaft 22 to drive the collecting gear shaft 22 to rotate, and the left driven collecting gear 23 and the lower right driven collecting gear 26 serve as auxiliary supporting gears. The left collecting crawler 24 and the right collecting crawler 27 can rotate to drive the collecting trough 28 to move vertically. During the vertical movement of the collecting trough 28, since the collecting trough 28 is hinged to the left collecting crawler 24 and the right collecting crawler 27, the collecting trough 28 can maintain a posture with the top opening facing upward.

[0047] The drive motor 14 is rotatably mounted at the top of the frame structure, and has two locking positions, and the drive motor 14 is switchably connected to the collection system and the transportation system in the two locking positions. In one embodiment, the rotation of the drive motor 14 can be achieved by an electric cylinder.

[0048] The collection system crawler 19 and the transport system in the collection system are located on two adjacent sides of the frame structure, which is convenient for the drive motor 14 to switch to drive the collection system or the transport system, and also convenient for the collection net 21 to deliver the collected materials to the collection tank 28.

[0049] The power supply device includes a solar bracket 12 and a solar panel and energy storage device 13, and the solar panel and energy storage device 13 are fixedly installed on the top of the frame structure through the solar bracket 12. In the solar panel and energy storage device 13, the solar panel is arranged horizontally, and the solar panel can absorb solar energy to generate electrical energy and store the electrical energy in the energy storage device, and the energy storage device can power the drive motor 14, the bait throwing drive motor 30, and the control module 38, the camera 39, and the water temperature sensor 40 described below.

[0050] Example 3

[0051] In this embodiment, a feeding system for evenly feeding bait into the interior of the frame structure is also installed on the top of the frame structure.

[0052] Specifically, the bait throwing system includes a bait throwing bracket 29, a bait throwing drive motor 30, a bait throwing drive gear 31, a bait throwing gear shaft 32, a bait throwing driven gear 33, a bait throwing crawler 34, a bait trough 35, a bait trough door 36 and a bait trough cover 37. The bait throwing drive gear 31 is connected to the output end of the bait throwing drive motor 30, the bait throwing driven gear 33 and the bait throwing gear shaft 32 are rotatably connected to the bait throwing bracket 29, the bait throwing crawler 34 surrounds the bait throwing driven gear 33 and the bait throwing gear shaft 32, and the bait throwing crawler 34 is connected to the bait throwing driven gear 33 and the bait throwing gear shaft 32. The bait driving gear 31 is connected to the bait throwing gear shaft 32 by power, the bait throwing bracket 29 has a horizontally arranged track, the bait trough 35 is slidably installed on the track, the top of the bait trough 35 has a detachable bait trough cover 37, the bottom of the bait trough 35 has a hollow hole, the bait trough door 36 is hinged to the bait trough 35, and the bait trough door 36 closes the hollow hole at the bottom of the bait trough 35 when in a free state; the power supply device is electrically connected to the bait throwing driving motor 30 to supply power to the bait throwing driving motor 30;

[0053] Both the bait trough 35 and the bait trough door 36 have passive shifting blocks, and the bait casting track 34 has an active shifting block; when the active shifting block is located in the upper rotating section of the bait casting track 34, it can cooperate with the passive shifting block of the bait trough 35 to drive the bait trough 35 to move horizontally in the first direction along the track; when the active shifting block is located in the lower rotating section of the bait casting track 34, it can cooperate with the passive shifting block of the bait trough door 36 to push the bait trough door 36 away from the hollow hole and drive the bait trough 35 to move horizontally in the second direction along the track.

[0054] In the present embodiment, there are two feeding brackets 29, which are respectively arranged on two upper horizontal tubes 2 arranged opposite to each other. The feeding bracket 29 is an inverted U-shaped structure, and the upper part of the feeding bracket 29 is a horizontally arranged track. Both ends of the bait trough 35 have a trough structure matching the cross-sectional shape of the track and are mounted on the track through the trough structure. The bait trough 35 is in the shape of a long strip, and the width of the bait trough 35 basically matches the distance between the two upper horizontal tubes 2 arranged opposite to each other.

[0055] like Figure 5As shown, when the bait feeding drive motor 30 drives the bait feeding gear shaft 32 to rotate, the bait feeding gear shaft 32 drives the bait feeding track 34 to rotate. When the rotating section on the bait feeding track 34 moves to the left, the active shift block on the bait feeding track 34 contacts the passive shift block opened on the side wall of the bait feeding trough 35 to drive the bait feeding trough 35, the bait feeding trough door 36 and the bait feeding trough cover 37 to move to the left as a whole. After the bait feeding trough 35 moves to the leftmost extreme position, the active shift block is driven to rotate by the bait feeding track 34, that is, it is separated from the passive shift block of the bait feeding trough 35. When the active block moves to the lower rotation interval, the active block contacts the passive block of the bait trough door 36. First, the bait trough door 36 is opened, and the bait in the bait trough 35 falls out of the bait trough 35. Then, the passive block on the bait trough door 36 does not separate from the active block, and the active block drags the bait trough 35 to move to the right. The bait continues to spread until the bait trough 35 moves to the rightmost limit position, and the active block separates from the passive block on the bait trough door 36. The bait trough door 36 is driven by gravity to fall and close the hollow hole at the bottom of the bait trough 35, completing a feeding cycle. The number of baits released in a feeding cycle is 1 unit, and the total feeding amount is N units of feeding amount. The drive motor 14 runs N cycles to achieve the target amount of this feeding.

[0056] In addition, the ecological cage device also has the ability to monitor and control. Specifically, the ecological cage device includes a control module 38, a camera 39 and a water temperature sensor 40.

[0057] The camera 39 is mounted on the solar support 12, with its image acquisition end facing the frame structure to acquire the image of the remaining bait;

[0058] A water temperature sensor 40 is installed on the side wall of the frame structure to obtain a water temperature signal;

[0059] The control module 38 is respectively connected to the camera 39 , the bait-casting drive motor 30 and the water temperature sensor 40 for communication. The control module 38 obtains the residual bait image and the water temperature signal, and issues a driving instruction to the bait-casting drive motor 30 .

[0060] The invention can improve the utilization rate of bait fundamentally, effectively reduce bait waste and lower environmental pollution by continuously collecting environmental factors, combining feeding time and residual bait amount, and automatically correcting and calculating each feeding amount.

[0061] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
