Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a breeding system for culturing crawfish. Background Art

[0002] In the field of aquaculture, some species may have defects in mixed culture due to their aggressive habits. Specifically, taking crayfish as an example, in the traditional pond culture and mixed culture process, the fighting behavior caused by living space, food resources, light and shelter will increase the rate of crayfish limb mutilation and some individuals will develop slowly. Severe fighting behavior may even affect the final survival rate and breeding benefits. In addition, traditional breeding systems usually require a larger area.

[0003] For this purpose, there are in the prior art a breeding box disclosed in the Chinese utility model patent "A crayfish parent breeding device" with patent number CN202220346894.X (publication number CN217160823U), and a breeding device disclosed in the Korean patent "Crab breeding device" with patent number KR20070114982 (publication number KR100821313B1). This type of breeding system adopts box breeding, which occupies a relatively small area, and in order to breed a large number of crayfish in a limited space and avoid fighting between crayfish, the internal space of the box used for breeding is divided into multiple independent spaces of the same size by using partitions, and a crayfish is cultured separately in each independent space to avoid fighting and interference between crayfish.

[0004] However, this type of aquaculture system still has the following defects in actual use: First, the multiple independent spaces divided by the partitions in the existing aquaculture system are often of fixed and uniform specifications, which may require the preparation of multiple sets of partition structures of different specifications when the crawfish are in different growth stages or when different batches of crawfish need to be cultivated. In terms of the production of the partitions, the production of partition structures of different specifications will also increase the cost. Therefore, the overall solution has a relatively high cost and is relatively inconvenient; second, the existing aquaculture system usually also includes a filtering device for circulating and purifying water quality, and the partition is set on the flow path of the aquaculture water, which may hinder the flow of the aquaculture water and affect the filtering effect. Therefore, it is necessary to further improve the existing aquaculture system. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a breeding system which can be adaptively adjusted according to the growth needs of crayfish at different stages in view of the above-mentioned existing technical status.

[0006] The second technical problem to be solved by the present invention is to provide a breeding system capable of reducing the obstruction of the partition to the flow of breeding water in view of the above-mentioned existing technical status.

[0007] The technical solution adopted by the utility model to solve the first technical problem is as follows: the culture system for crawfish includes a frame for providing a culture space for cultured objects, a partition is arranged in the frame, the edge around the partition cooperates with the inner wall of the frame to divide the frame into at least one pair of sub-frame groups, each pair of the sub-frame groups is arranged in parallel, and each group of the sub-frame groups is composed of at least two sub-frames arranged front and back, and is characterized in that: an adjustment member capable of synchronously adjusting the space required by each group of the sub-frame groups is also arranged in the frame.

[0008] In order to enable the adjusting member to synchronously adjust the space required for each group of sub-frames, preferably, the adjusting member is plugged with the separator to synchronously change the space required for the sub-frames arranged front and back in each pair of the sub-frame groups in any row and / or column. It should be noted that, in the case of limited length or width, the space required for the sub-frames arranged front and back in each pair of the sub-frame groups in any row and / or column can also be changed by increasing or reducing the plugged separators or adjusting members.

[0009] In order to realize that the adjusting member can change the space required by the sub-frame by interlocking with the partition, preferably, the partition is a partition, which is divided into two parts along the height direction, including a first section in the shape of a plate and a second section in the shape of a comb strip, and the gap between each two adjacent comb strips forms an insertion part for inserting the adjusting member. Such a design enables the adjusting member to be inserted into different insertion parts on the second section of the partition, thereby realizing synchronous adjustment of the space required by each group of sub-frames.

[0010] Further design, in order to simplify the structure of the partition and the adjusting member, preferably, the adjusting member and the partition have the same structure, and in the mating state, the two are arranged in opposite directions. Since the partition is divided into two in the height direction, when the two are arranged in opposite directions and mated with each other, the end face of the first section of the adjusting member can overlap with the end face of the second section of the partition; in addition, the adjusting member and the partition have the same structure, but can be processed into different lengths according to actual needs.

[0011] In order to strengthen the structure of the mutually mating separator and the adjusting member, preferably, the separator and the adjusting member are arranged perpendicular to each other and a fixing member is sleeved at the mutually staggered position, and the fixing member is provided with a matching portion adapted to the mutually staggered position of the separator and the adjusting member. The matching portion can be set as, for example, a cross-shaped groove, or a clamping structure, etc.

[0012] In order to solve the second technical problem, preferably, the aquaculture system includes a filtering device for circulating and purifying aquaculture water, and the frame is provided with at least one inlet for aquaculture water to pass through, and flows into each of the sub-frames by means of the insertion portion of the partition. Since the insertion portion is the gap between each two adjacent comb strips, the aquaculture water can flow, thereby reducing the obstruction of the partition to the flow of aquaculture water.

[0013] In order to facilitate the residual bait and excrement to leave the sub-frame to keep the breeding environment clean, preferably, the bottom edge of the partition is connected with a filter net that can allow the residual bait and excrement to flow out. The filter net can be connected to the bottom edge of the partition by bonding or other detachable methods. The filter net can, on the one hand, keep the bait in the sub-frame and the residual bait and excrement out of the sub-frame; on the other hand, when the partition is removed from the frame, the breeding object can be taken out at the same time without carrying impurities such as residual bait and excrement.

[0014] In order to connect the filter to the bottom edge of the partition, preferably, a frame is provided on the periphery of the filter, and a slot is provided on the frame for inserting the partition and / or the adjusting member. By inserting the partition and / or the adjusting member into the slot, the filter can be detachably fixed to the bottom edge of the partition; in addition, a supporting structure can be provided under the frame to keep a certain gap between the filter and the bottom of the frame, which is conducive to the residual bait and excrement leaving the sub-frame, and is also conducive to the circulation of aquaculture water.

[0015] In order to cultivate more breeding objects in a limited space and maintain the water quality of breeding water at the same time, preferably, the breeding system includes at least two frames, the filtering device and each frame are connected by a pipe fitting fluid to circulate the breeding water, the filtering device includes a filter box located below the frame, a filter material is arranged in the filter box, the pipe fitting extends from the frame at the downstream end of the breeding water flow path to the bottom of the filter box, and an outflow port is opened in the upper section of the side wall of the filter box. With such a design, the breeding water will flow to the bottom of the filter box and gradually overflow to the upper part of the filter box. In this process, the breeding water will be filtered by the filter material, and the filter material can be selected from filter materials such as moving bed biological fluidized bed fillers; in addition, the structure allows impurities such as residual bait and excrement to settle at the bottom of the filter box. If a valve is arranged at the bottom of the filter box, the residual bait and excrement impurities can be discharged more conveniently; of course, according to actual needs, the arrangement in the filter box can also adopt other applicable forms.

[0016] In order to realize the circulation of aquaculture water, preferably, the filtering device also includes a water storage tank, the outflow port is provided with a pipe extending to the top of the water storage tank, and the water storage tank is provided with a pump body connected to the frame fluid at the upstream head end of the aquaculture water flow path through the pipe. The aquaculture water flows from the water storage tank to the upstream frame through the pump body, and the aquaculture water can flow through all the frames and flow from the downstream frame to the filter box. Finally, the aquaculture water can return to the water storage tank after being filtered by the filter material to complete the cycle; and according to actual needs, other devices such as a temperature control device or an oxygenation device can also be set in the water storage tank.

[0017] The "fluid communication" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.

[0018] Compared with the prior art, the advantages of the utility model are:

[0019] 1. Through the adjustment parts set in the frame, the space required by each group of sub-frames can be adjusted synchronously to meet the needs of different growth stages of the breeding objects, and only one specification of partition can be used, with a simple structure and low cost;

[0020] 2. An insertion portion is formed through the gap between each two adjacent comb strips on the partition, so that the aquaculture water can flow into each sub-frame through the insertion portion, thereby reducing the obstruction of the partition to the flow of aquaculture water.

[0032] The present invention is further described in detail below in conjunction with specific embodiments.

[0033] like Figures 1 to 9 As shown in FIG. , it is a preferred embodiment of the present utility model. Figure 1 As shown, the culture system for crawfish in this embodiment includes a frame 1 for providing a culture space 11 for cultured objects, and a partition 2 is provided in the frame 1. The edge of the partition 2 cooperates with the inner wall of the frame 1 to divide the frame 1 into at least one pair of sub-frame groups 12. Each pair of sub-frame groups 12 is arranged side by side, and each sub-frame group 12 is composed of at least two sub-frames 121 arranged front to back. An adjustment member 3 capable of synchronously adjusting the space required for each sub-frame group 12 is also provided in the frame 1. In addition, the culture system in this embodiment also includes a frame T, on which four frames 1 are provided. Specifically, in order to enable the adjustment member 3 to synchronously adjust the space required for each sub-frame group 12, as shown in FIG. Figure 2 , 3 As shown, the adjusting member 3 is mated with the partition 2 to synchronously change the space required for the sub-frames 121 arranged front to back in each pair of sub-frame groups 12 in any row and / or column. It should be noted that, in the case of limited length or width, the space required for the sub-frames 121 arranged front to back in each pair of sub-frame groups 12 in any row and / or column can also be changed by increasing or decreasing the mated partitions 2 or adjusting members 3.

[0034] Further, see Figure 4, the partition 2 in this embodiment is a partition, which is divided into two parts in the height direction, including a first section 21 in the form of a plate and a second section 22 in the form of a comb strip, and the gap between each two adjacent comb strips 23 forms an insertion section 24 for inserting the adjusting member. The adjusting member 3 and the partition 2 in this embodiment have the same structure, and in the plugged-in state, the two are set in opposite directions. Since the partition is divided into two parts in the height direction, when the two are in the reverse setting and plugged in to each other, the end face of the first section 21 of the adjusting member 3 can coincide with the end face of the second section 22 of the partition 2; in addition, the adjusting member 3 and the partition 2 are the same in structure, but can be processed into different lengths according to actual needs. The partition 2 in this embodiment is slightly shorter than the adjusting member 3. In order to strengthen the structure of the partition 2 and the adjusting member 3 that are plugged in to each other, the partition 2 and the adjusting member 3 are arranged perpendicular to each other and are sleeved with a fixing member 4 at the mutually staggered position, and the fixing member 4 is provided with a matching portion 41 adapted to the mutually staggered position of the partition 2 and the adjusting member 3. As Figure 5 As shown, the matching portion 41 in this embodiment is a cross-shaped groove.

[0035] The aquaculture system in this embodiment also includes a filtering device 5 for circulating and purifying aquaculture water, see Figure 7 , the dotted arrow in the figure indicates the flow direction of aquaculture water. The frame 1 is provided with at least one inlet 13 for aquaculture water to pass through, and the water flows into each sub-frame 121 with the help of the insertion part 24 of the partition 2. Since the insertion part 24 is the gap between each two adjacent comb strips 23, it can allow aquaculture water to flow, thereby reducing the obstruction of the partition to the flow of aquaculture water. It is further designed that in order to facilitate the residual bait and excrement to leave the sub-frame 121 to keep the aquaculture environment clean, the bottom edge of the partition 2 is connected with a filter net 6 through which the residual bait and excrement can flow out. The filter net 6 can be connected to the bottom edge of the partition 2 by bonding or other detachable methods. The filter net 6 can, on the one hand, keep the bait in the sub-frame 121 and the residual bait and excrement leave the sub-frame 121; on the other hand, when the partition 2 is removed from the frame 1, the aquaculture object can be taken out at the same time, and impurities such as residual bait and excrement will not be carried. See. Figure 6 In this embodiment, a frame 61 is provided on the periphery of the filter screen 6, and a slot 62 for inserting the partition 2 and / or the adjusting member 3 is provided on the frame 61. By inserting the partition 2 and / or the adjusting member 3 into the slot 62, the filter screen 6 can be detachably fixed to the bottom edge of the partition 2. In addition, in this embodiment, a support structure is provided below the frame 61 to keep a certain gap between the filter screen 6 and the bottom of the frame 1, which is conducive to the residual bait and excrement leaving the sub-frame 121, and is also conducive to the circulation of aquaculture water.

[0036] In addition, in order to breed more aquaculture objects in a limited space and maintain the water quality of aquaculture water, see Figure 8 In this embodiment, the aquaculture system is provided with four frames 1 on the frame T, and the filter device 5 is fluidly connected to each frame 1 through a pipe 51 to allow the aquaculture water to circulate. Fig. 9 As shown, the filter device 5 includes a filter box 52 located below the frame 1, a filter material 53 is arranged in the filter box 52, a pipe 51 extends from the frame 1 at the downstream end of the aquaculture water flow path to the bottom of the filter box 52, and an outflow port 54 is provided on the upper section of the side wall of the filter box 52. With such a design, the aquaculture water will flow to the bottom of the filter box 52 and gradually overflow to the upper part of the filter box 52. In this process, the aquaculture water will be filtered by the filter material 53. The filter material 53 in this embodiment is a moving bed biological fluidized bed filler. In addition, this structure allows impurities such as residual bait and excrement to be deposited at the bottom of the filter box 52, and a valve V is arranged at the bottom of the filter box 52 in this embodiment, so that impurities such as residual bait and excrement can be discharged more conveniently. And a movable base C is arranged below the filter box 52 to facilitate moving the heavier filter box 52 out from under the frame T for cleaning. Finally, in order to realize the circulation of aquaculture water, the filtering device 5 in this embodiment also includes a water storage tank 55, and the outlet 54 is provided with a pipe 51 extending to the top of the water storage tank 55. The water storage tank 55 is provided with a pump body 56 which is in fluid communication with the frame 1 at the upstream head end of the aquaculture water flow path through the pipe 51. The aquaculture water flows from the water storage tank 55 to the upstream frame 1 through the pump body 56, and the aquaculture water can flow through all the frames 1 and flow from the downstream frame 1 to the filter box 52. Finally, the aquaculture water can return to the water storage tank 55 after being filtered by the filter material 53, thereby completing the circulation. In addition, a temperature control device and an oxygenation device are also provided in the water storage tank 55 in this embodiment.

[0037] The specific use process of the separator 2 and the adjusting member 3 provided in this embodiment is as follows:

[0038] See also Fig.10 At this time, the partitions 2 and the adjusting members 3 are in the first state, that is, the six partitions 2 and the five adjusting members 3 divide the breeding space 11 in the frame 1 into five columns and four rows of sub-frames 121; see Fig.11 At this time, the separator 2 and the adjusting member 3 have entered the second state. Compared with the first state, two separators 2 and one adjusting member 3 are reduced, and the sub-frames 121 are changed to three columns and three rows, and the specifications of each sub-frame 121 are increased. In this case, the specifications of all sub-frames 121 are changed synchronously, and of course, the space required for the sub-frames 121 arranged front and back in each pair of sub-frame groups 12 in any row and / or column can also be changed synchronously as needed.
