Description
Technical Field
[0001] This utility model relates to the field of aquaculture pond technology, and in particular to a small green dragon aquaculture pond with a dividing net. Background Technology
[0002] The small green crayfish is a freshwater shrimp species with high economic value. Its scientific name is Redclaw Crayfish, and it is also known as Green Dragon, Green Shell Crayfish, and Salmon. In the process of farming small green crayfish, it is necessary to provide a breeding pond to provide a breeding place for them.
[0003] The current method of raising small green crayfish involves placing the rearing tank on the ground, filling it with fresh water suitable for the crayfish's survival, and then placing the crayfish in the tank for cultivation. However, due to the relatively simple space of the rearing tank, the stocking density of small green crayfish in the tank may be high, leading to an overabundance of shrimp larvae and competition for survival, resulting in an increase in the number of dead or damaged shrimp and affecting the production capacity of the aquaculture. Utility Model Content
[0004] The technical problem this invention aims to solve is that the relatively simple space of the aquaculture tank may lead to a high stocking density of small green crayfish, resulting in an overabundance of shrimp larvae and competition for survival, which in turn increases the number of uninhabited or dead shrimp and affects aquaculture production capacity.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a small green dragon breeding pond with a dividing net, comprising: a breeding trough, which is placed on the ground to carry water and small green dragons; a water outlet pipe, which is installed on the breeding trough and is used to discharge wastewater; and a dividing component, which is placed inside the breeding trough to divide the breeding space inside the breeding trough into multiple areas for the breeding of small green dragons in different areas.
[0006] Preferably, the separating component includes: a screw rod, which is fixedly connected to the inner wall of the aquaculture tank, wherein the surface of the screw rod is threaded with a threaded ring; and a screen, wherein the screen is sleeved on the screw rod by a sleeve, wherein the sleeve is fixed on the screw rod by compression through the threaded ring, and wherein the screen has a double-layer structure.
[0007] The effects achieved by the above components are as follows: By setting up the dividing components, the net is first moved manually, causing the net to move the sleeve. When the sleeve is fully moved and fitted onto the screw, the net is fully inserted into the breeding tank. At this time, the screw hole ring is manually rotated, causing the screw hole ring to move up and down along the surface of the screw. The screw hole ring moves to the position of pressing the sleeve surface, fixing the sleeve and net in place. This fixes the net inside the breeding tank, dividing the breeding area inside the tank into multiple separate breeding spaces. At the same time, it separates the crayfish inside the breeding tank, achieving separate breeding of crayfish. This reduces the situation where the high breeding density of crayfish in the breeding tank leads to overpopulation of crayfish larvae, resulting in competition for survival, an increase in the number of dead or damaged crayfish, and an impact on breeding capacity. This improves the space utilization rate of the breeding tank.
[0008] Preferably, the separating component further includes a screw ring, which is fixed to the screw hole ring, wherein the screw ring is sleeved on the screw, and wherein the surface of the screw ring is provided with a plurality of protrusions.
[0009] The effect achieved by the above components is that by setting the screw ring, the contact area of the screw hole ring can be increased, thereby improving the convenience and stability of manually rotating the screw hole ring.
[0010] Preferably, the separating component further includes a rubber pad, wherein the rubber pad is fixed to the bottom of the barrier net to fill the gap between the barrier net and the aquaculture tank.
[0011] The effect achieved by the above-mentioned components is that by setting rubber pads, the gap between the net and the inner wall of the breeding tank can be filled and sealed, reducing the possibility of shrimp larvae entering other areas through the gaps.
[0012] Preferably, the separating component further includes a sealing cylinder, which is fixedly connected to the inner wall of the aquaculture tank, wherein the sealing cylinder, together with a sealing gasket, wraps around and seals the screw and the sleeve.
[0013] The effect achieved by the above components is as follows: by setting a sealing cylinder, the sealing cylinder can work with the sealing gasket to wrap the sleeve on the screw and fill and seal the gap between the two. At the same time, the sealing cylinder can fill the gap between the screw and the side wall of the breeding tank, reducing the possibility of shrimp larvae turning over to other areas through the gap.
[0014] Preferably, the separating component further includes a sealing plate, wherein the sealing plate is placed inside the barrier net to completely seal the holes in the barrier net, and wherein the sealing plate is made of rubber.
[0015] The effect achieved by the above components is that by setting up a sealing plate, personnel can insert the sealing plate into the inside of the barrier to seal the holes in the barrier and intercept the water flow, allowing the aquaculture tank to be used for localized aquaculture.
[0016] Preferably, the device further includes: a sunshade device comprising: a threaded rod rotatably mounted on the aquaculture tank via a bearing bracket, wherein the threaded rod is driven by a motor, and the surface of the threaded rod is threadedly connected to a threaded hole rod; a perforated plate fixedly attached to the aquaculture tank; a fabric rolling rod rotatably mounted on the perforated plate via a bearing, wherein a coil spring is fixedly connected between the fabric rolling rod and the perforated plate, wherein one end of the coil spring is fixedly connected to the fabric rolling rod, and the other end is fixedly connected to the perforated plate; and a sunshade cloth, wherein both ends of the sunshade cloth are fixedly connected to the fabric rolling rod and the threaded hole rod respectively, wherein the fabric rolling rod rotates under the drive of the coil spring and rolls up the sunshade cloth.
[0017] The effect achieved by the above-mentioned components is as follows: by setting up a shading device, the motor is first started, which drives the threaded rod to rotate. The threaded rod then moves the threaded hole rod left and right. During the movement, the threaded hole rod pulls the shading cloth rolled on the cloth rolling rod, causing the shading cloth to slowly unfold and gradually cover the top of the breeding tank. The shading cloth covering the breeding tank blocks the outside sunlight, thereby achieving shading treatment for the breeding tank. This reduces the possibility of the breeding tank being exposed to strong sunlight for a long time, which could lead to a sharp rise in water temperature and cause heat stress or even death in shrimp larvae.
[0018] Preferably, the shading device further includes a guide rod, which is fixed to the aquaculture tank, wherein the guide rod is placed inside the threaded rod to limit its movement on the side away from the threaded rod.
[0019] The effect achieved by the above components is that by setting the guide rod, the guide rod can be placed inside the threaded rod to limit the end of the threaded rod away from the threaded rod, thereby reducing the shaking or rotation of the threaded rod during movement.
[0020] The beneficial effects of this utility model are:
[0021] By setting up partition components, the internal breeding space of the breeding tank can be divided into multiple separate spaces, and the crayfish can be raised in different areas. This reduces the situation where the high breeding density of crayfish in the breeding tank leads to an overabundance of crayfish larvae and competition for survival, resulting in an increase in the number of dead or damaged crayfish and affecting the breeding capacity. This improves the space utilization rate of the breeding tank. Attached Figure Description

[0031] Figure 1-5 The illustrated small green dragon breeding pond with a dividing net includes: a breeding tank 1, which is placed on the ground to hold water and small green dragons; a water outlet pipe 2, which is installed on the breeding tank 1 and is used to discharge wastewater; and a dividing component 3, which is placed inside the breeding tank 1 to divide the breeding space inside the breeding tank 1 into multiple areas for the separate breeding of small green dragons.
[0032] Figure 2 , Figure 3 and Figure 4The partition assembly 3 shown includes: a screw 31, which is fixedly connected to the inner wall of the aquaculture tank 1, wherein a threaded ring 33 is threaded onto the surface of the screw 31; and a mesh 36, which is fitted onto the screw 31 by a sleeve 35, wherein the sleeve 35 is fixed onto the screw 31 by the threaded ring 33. The mesh 36 has a double-layer structure. By setting up the partition assembly 3, the mesh 36 is first manually moved, causing the sleeve 35 to move. When the sleeve 35 moves completely onto the screw 31, the mesh 36 is fully inserted into the aquaculture tank 1. At this time, the threaded ring 33 is manually rotated. The screw ring 33 moves up and down along the surface of the screw 31, and moves to the position of the extrusion sleeve 35 to fix the sleeve 35 and the net 36 in place. The net 36 is fixed inside the breeding tank 1, dividing the breeding area inside the breeding tank 1 into multiple separate breeding spaces. At the same time, it separates the crayfish inside the breeding tank 1, achieving separate breeding of crayfish. This reduces the situation where the high breeding density of crayfish in the breeding tank 1 leads to the overpopulation of crayfish seedlings and competition for survival, resulting in an increase in the number of dead or damaged crayfish and affecting the breeding capacity. This improves the space utilization rate of the breeding tank 1.
[0033] Figure 2 , Figure 3 and Figure 4 The partition assembly 3 also includes a screw ring 34, which is fixed to the screw hole ring 33. The screw ring 34 is sleeved on the screw rod 31. The surface of the screw ring 34 has multiple protrusions. By setting the screw ring 34, the contact area of the screw hole ring 33 can be increased, improving the convenience and stability of manually rotating the screw hole ring 33. The partition assembly 3 also includes a rubber pad 38, which is fixed to the bottom of the net 36 to fill the gap between the net 36 and the aquaculture tank 1. By setting the rubber pad 38, the gap between the net 36 and the inner wall of the aquaculture tank 1 can be filled and sealed, reducing the possibility of shrimp larvae entering other areas through the gap.
[0034] Figure 2 , Figure 3 and Figure 4The partition assembly 3 also includes a sealing cylinder 32, which is fixedly connected to the inner wall of the aquaculture tank 1. The sealing cylinder 32, together with the sealing gasket, wraps and seals the screw 31 and the sleeve 35. By setting the sealing cylinder 32, the sealing cylinder can wrap the sleeve 35 fitted on the screw 31 with the sealing gasket and fill and seal the gap between the two. At the same time, the sealing cylinder 32 can fill the gap between the screw 31 and the side wall of the aquaculture tank 1, reducing the possibility of shrimp larvae crossing over to other areas through the gap. The partition assembly 3 also includes a sealing plate 37, which is placed inside the net 36 to completely seal the holes of the net 36. The sealing plate 37 is made of rubber. By setting the sealing plate 37, personnel can insert the sealing plate 37 into the net 36 to seal the holes of the net 36 and intercept the water flow, so that the aquaculture tank 1 can be used for localized aquaculture.
[0035] Figure 3 and Figure 5 The device also includes: a sunshade device 4, comprising: a threaded rod 41, which is rotatably mounted on the aquaculture tank 1 via a bearing bracket, wherein the threaded rod 41 is driven by a motor, and a threaded hole rod 43 is threadedly connected to the surface of the threaded rod 41; a perforated plate 45, which is fixedly connected to the aquaculture tank 1; a fabric rolling rod 46, which is rotatably mounted on the perforated plate 45 via a bearing, wherein a coil spring is fixedly connected between the fabric rolling rod 46 and the perforated plate 45, wherein one end of the coil spring is fixedly connected to the fabric rolling rod 46 and the other end is fixedly connected to the perforated plate 45; and a sunshade cloth 44, wherein both ends of the sunshade cloth 44 are fixedly connected to the fabric rolling rod 46 and the threaded hole rod 43 respectively, wherein the fabric rolling rod... Driven by the coil spring, 46 rotates and rolls up the shading cloth 44. By setting up the shading device 4, the motor is first started, which drives the threaded rod 41 to rotate. The threaded rod 41 drives the threaded hole rod 43 to move left and right. During the movement, the threaded hole rod 43 pulls the shading cloth 44 rolled on the rolling rod 46, so that the shading cloth 44 slowly unfolds and gradually covers the top of the breeding tank 1. The shading cloth 44 covering the breeding tank 1 blocks the outside sunlight, thereby achieving the shading treatment of the breeding tank 1. This reduces the situation where the breeding tank 1 is exposed to strong sunlight for a long time, which can cause the water temperature to rise sharply and cause heat stress or even death of shrimp larvae.
