Description

Technical Field

[0001] The invention belongs to the technical field of breeding equipment, and in particular relates to a Procambarus clarkii breeding pond. Background Art

[0002] The breeding pond of Procambarus clarkii is one of the most critical links in the entire breeding process, which is directly related to the quality and quantity of seedlings. The water source must ensure sufficient and clean water supply and discharge at all times. The water quality must meet fishery standards, be pollution-free, low in heavy metals and low in pesticide residues.

[0003] Chinese Patent Publication No. CN110140682A discloses a dual-purpose pond for breeding and aquaculture of Procambarus clarkii, comprising: a breeding pond, a culturing pond, and a circular pipe. The breeding pond is less deep than the culturing pond and is fixedly disposed adjacent to the culturing pond. A slope is fixedly disposed on the bottom of the breeding pond. The lower end of the circular pipe is vertically fixed on the slope. The upper end of the circular pipe is open, and the upper end surface of the circular pipe is flush with the upper end surface of the culturing pond. A flow hole is provided in the lower portion of the circular pipe. The breeding pond and the culturing pond are connected through the circular pipe. This overcomes the drawback of existing mixed culture of Procambarus clarkii, which results in fighting and cannibalism between Procambarus clarkii at different growth stages, and thus leads to low Procambarus clarkii yield. The breeding process and the culturing process of Procambarus clarkii can be separated, thereby increasing the Procambarus clarkii yield and improving the disease resistance of Procambarus clarkii.

[0004] During the actual use of the above-mentioned breeding pond, there are dead corners in the water at the bottom of the pond, so the dissolved oxygen content will continue to decrease. Due to the high oxygen consumption required for the development of shrimp egg embryos in the early stage of incubation, it is easy to cause insufficient oxygen intake of female shrimps, which in turn leads to the death of shrimp eggs. When using ordinary water changers, due to large water flow fluctuations, excessive water flow impact may cause the slender egg stalk attached to the swimming feet on the abdomen of the female shrimp to break, thereby causing the eggs to fall off, increasing the probability of the female shrimp kicking or eating eggs.

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figure 1-Figure 7 In one embodiment of the present invention, a crayfish breeding pond has a relative first direction x, a second direction y, and a third direction z, and includes a breeding pond module and a pump module. The breeding pond module is used to place female shrimps carrying eggs. One end of the pump module is arranged at the bottom side of the breeding pond module, and is used to return aerated circulating water to the breeding pond to increase the dissolved oxygen content of the bottom water. The circulating water stirs the excrement and feed at the bottom of the pond during the pumping process so that the remaining feed is captured and eaten by the female shrimps; the breeding pond module includes a pond body assembly 1, the pond body assembly 1 includes a breeding pond 101 and a return pond 102, and the breeding pond 101 and the return pond 102 are independently arranged; the pump module includes a pump flow assembly 2 and a flow release assembly 3, the pump flow assembly 2 is used to pump the aerated water in the return pond 102 into the breeding pond 101, and the flow release assembly 3 is used to release the aerated water to the bottom side of the breeding pond.

[0025] In actual application of this embodiment, the breeding pond module includes a pond body component 1, and the pond body component 1 includes a breeding pond 101 and a reflow pond 102. The breeding pond 101 is used to place female shrimps to be hatched, and the reflow pond 102 is used to reflow the breeding water in the breeding pond 101, and increase the dissolved oxygen content in the breeding water by aeration, and pump the high-oxygen breeding water to the bottom side of the breeding pond 101 through the pumping module. Since the oxygen consumption required for embryonic development in the early stage of incubation is high and the dissolved oxygen content of the water body needs to be greater than 5 mg / L, and there is a dead corner in the water body at the bottom of the pond, its dissolved oxygen content continues to decrease with time, which can easily cause insufficient oxygen uptake of the female shrimps at the bottom of the pond. , which leads to the death of shrimp eggs. When using a conventional water changer, due to the large fluctuations in water flow, the strong water flow impact may cause the delicate egg stalk attached to the swimming feet of the female shrimp's abdomen to break, thereby causing the eggs to fall off. Moreover, when the shrimp with eggs feel the strong water flow impact, they will vigorously flap their abdomens to try to protect the egg mass, which in turn increases the probability of the egg mass falling off or the female shrimp kicking / eating the eggs. This embodiment returns the aerated circulating water to the breeding pond and allows the circulating water to flow into the breeding pond at a low speed. While realizing the circulation water exchange from the bottom of the cavity to the top of the cavity, it reduces the direct impact of strong water flow on the shrimp eggs, thereby reducing the energy consumed by the female shrimp to resist the water flow, and preventing it from affecting the normal development of the shrimp eggs.

[0026] See also Figure 2 and Figure 3 In a preferred embodiment of the present invention, the pool body assembly 1 further includes an overflow hole 103, a reflux hole 104 and a guide groove 105. The overflow hole 103 is arranged on one side of the cavity wall of the breeding pool 101, and the reflux hole 104 is arranged on one side of the cavity wall of the return pool 102. The guide groove 105 is fixedly arranged outside the breeding pool 101 and the return pool 102, and the guide groove 105 connects the overflow hole 103 and the reflux hole 104.

[0027] In actual application of this embodiment, the overflow hole 103 is set on the cavity wall of the breeding pool 101. When the circulating water of the return pool 102 is continuously pumped into the breeding pool 101, the water level in the breeding pool 101 continues to rise, so that the aquaculture water at the liquid surface end overflows into the guide groove 105 through the overflow hole 103. Since the other end of the guide groove 105 is connected to the return hole 104, the aquaculture water can flow back to the return pool 102 through the return hole 104, thereby realizing the circulation of the aquaculture water.

[0028] See also Figure 5In a preferred embodiment of the present invention, the pump flow assembly 2 includes a pump flow cylinder 201, a shaft 202, a piston 203 and a bubble generator 204. The pump flow cylinder 201 is fixedly arranged in the reflux pool 102. The shaft 202 is movably inserted into one end of the pump flow cylinder 201. The piston 203 is arranged in the inner cavity of the pump flow cylinder 201 and is fixedly connected to the shaft 202. The bubble generator 204 is arranged on the bottom side of the cavity of the reflux pool 102 for pumping air into the reflux pool 102. The pump flow assembly 2 also includes a pre- The suction pipe 205, the front exhaust pipe 206, the rear suction pipe 207, the rear discharge pipe 208 and the water supply tank 209, the pump flow cylinder 201 is provided with a relative first cavity a1 and a second cavity a2 with the piston 203 as a partition layer, the front suction pipe 205 and the front exhaust pipe 206 are both arranged on the side of the first cavity a1, the rear suction pipe 207 and the rear discharge pipe 208 are both arranged on the side of the second cavity a2, and the water supply tank 209 is arranged at the bottom of the breeding tank 101 and is communicated with the rear discharge pipe 208.

[0029] In actual application of this embodiment, the pump flow cylinder 201 is fixedly set in the reflux pool 102, and the shaft 202 reciprocates in the first direction x. Since the pump flow cylinder 201 is provided with a relative first cavity a1 and a second cavity a2 with the piston 203 as a separation layer, when the shaft 202 moves in the positive direction of the first direction x, the first cavity a1 is in a negative pressure state and the second cavity a2 is in a positive pressure state. Similarly, when the shaft 202 moves in the negative direction of the first direction x, the first cavity a1 is in a positive pressure state and the second cavity a2 is in a negative pressure state, so that the first cavity a1 and the second cavity a1 have opposite positive and negative pressure states.

[0030] See also Figure 5 In a preferred embodiment of the present invention, one-way check valves are provided on the front intake pipe 205, the front exhaust pipe 206, the rear intake pipe 207 and the rear discharge pipe 208 to limit the fluid to move in one direction along the front intake pipe 205 to the inner cavity of the pump flow cylinder 201, to limit the fluid to flow in one direction along the inner cavity of the pump flow cylinder 201 to the front exhaust pipe 206, to limit the fluid to flow in one direction along the rear intake pipe 207 to the inner cavity of the pump flow cylinder 201, to limit the fluid to flow in one direction along the inner cavity of the pump flow cylinder 201 to the rear discharge pipe 208.

[0031] In actual application of this embodiment, the front air intake pipe 205 and the front air exhaust pipe 206 are connected to the first cavity a1 side. When the first cavity a1 is in a negative pressure state, the front air intake pipe 205 draws gas from the external environment and pumps it into the first cavity a1. When the first cavity a1 is in a positive pressure state, the front air exhaust pipe 206 pumps the gas in the first cavity a1 into the bubble generator 204. The surface of the bubble generator 204 is provided with a plurality of micro air holes so that the pumped gas is released into the reflux pool 10 in the form of micro bubbles. 2, at the same pumping volume, since the contact area between the microbubbles and the liquid is larger, the solubility in the water can be increased, thereby improving the dissolved oxygen content of the circulating water. When the second cavity a2 is in a negative pressure state, the rear suction pipe 207 draws the circulating water from below the liquid surface of the reflux tank 102 into the second cavity a2. When the second cavity a2 is in a positive pressure state, the rear discharge pipe 208 continuously pumps the circulating water in the second cavity a2 into the water supply tank 209, and releases the circulating water into the breeding tank 101 through the water supply tank 209.

[0032] Furthermore, the front air intake pipe 205 can be connected to the outside atmosphere or an oxygen tank, and the air supply mode can be adjusted according to the current temperature and dissolved oxygen content.

[0033] See also Figure 6 In a preferred embodiment of the present invention, the flow release assembly 3 includes a groove member 301, a side tube groove 302, a flow release shell 303, a top groove 304, an upper cover 305, a flow release hole 306, a flexible brush 307 and a bottom groove 308. Several of the groove members 301 are arranged in an array on the bottom side of the breeding pool 101 and are connected to the water supply tank 209. The groove members 301 are arranged at intervals, and both sides of the groove member 301 are provided with The side cylinder groove 302, the flow release shell 303 is rotatably set in the side cylinder groove 302 of the two adjacent groups of groove parts 301, and a top groove 304 is arranged at the bottom of the flow release shell 303. An upper cover plate 305 is assembled on the top groove 304. A plurality of flow release holes 306 are arranged in an array on the upper cover plate 305. A plurality of flexible brushes 307 are also fixedly set in the middle of the upper cover plate 305. A bottom groove opening 308 is also provided at the bottom of the flow release shell 303.

[0034] In actual application of this embodiment, several of the shaped groove members 301 are arranged in an array on the bottom side of the cavity of the breeding pool 101, and side tube grooves 302 are provided on both sides of the shaped groove members 301. The flow release shell 303 is rotatably arranged in the side tube grooves 302 of two adjacent groups of shaped groove members 301, and an upper cover 305 is assembled in the top groove 304 on the top of the flow release shell 303. Several flow release holes 306 are arranged on the surface of the upper cover 305. A bottom groove opening 308 is provided at the bottom of the flow release shell 303. The bottom groove opening 308 is connected to the water supply tank 209, so that when the rear discharge pipe 208 pumps the circulating water, the circulating water passes through the water supply tank 2 09 enters the bottom of the groove part 301. Since a flow release shell 303 is rotatably assembled between two adjacent groups of groove parts 301, and a bottom groove opening 308 is arranged at the bottom of the flow release shell 303, the circulating water passes through the bottom groove opening 308 and enters the inner cavity of the flow release shell 303, and is released into the breeding pool 101 along the flow release hole 306 at the top of the flow release shell 303. The water supply tank 209 here is connected with several flow release shells 303, so that the pumped circulating water is synchronously released into the breeding pool 101 through several flow release holes 306. Therefore, the water flow rate pumped in a single flow release shell 303 is very small, and the disturbance to the female shrimp can be ignored, thereby increasing the oxygen uptake of the female shrimp.

[0035] Furthermore, a plurality of flexible brushes 307 are fixedly provided on the surface of the upper cover plate 305. The flexible brushes 307 can gently stroke the eggs of the female shrimp while following the rotation of the flow release shell 303, and can imitate the female shrimp's regular flapping of its swimming feet to remove impurities attached to the surface of the eggs. At the same time, the feed at the bottom of the pond can also be stirred. The two adjacent groups of groove members 301 are provided with a first curved surface b1 and a second curved surface b2 relative to each other. When the flow release shell 303 rotates toward the first curved surface b1, the flexible brushes 307 push the residual feed accumulated on the upper cover plate 305 toward the first curved surface b1. When the flow release shell 303 rotates to the first curved surface b 1, the plurality of discharge holes 306 on the side of the upper cover plate 305 are blocked by the side tube groove 302. Under the Bernoulli principle, the flow velocity on the side of the remaining discharge holes 306 increases, so that the pumped water flow pushes the residual feed out along the inclined wall of the first curved surface b1, so that the remaining feed at the bottom of the pond is in a floating state, thereby increasing the probability of being eaten by female shrimps and preventing the residual feed from accumulating at the bottom of the pond and causing rot and disease. Similarly, when the discharge shell 303 rotates to the side of the second curved surface b2, it can push the feed to the side of the second curved surface b2. In the process of alternating movement, the residual feed at the bottom of the breeding pond 101 can be evenly dispersed.

[0036] Furthermore, when the flow hole 306 is not blocked, the flow rate of the pumped water is very low, and the disturbance to the female shrimp is negligible.

[0037] Furthermore, since shrimps like to hide in grooves, most of the placed female shrimps hide in the grooves between the two sets of groove members 301. When the flow release hole 306 is in a partially blocked state, the pumped water flows along the inclined wall of the curved surface and is not directly pumped out toward one side of the shrimp body. Therefore, the impact on the shrimp can be ignored.

[0038] See also Figure 4 In a preferred embodiment of the present invention, the transmission component 4 includes a driven plate 401, a driven push plate 402, a driving rack 403, a driven gear 404 and a sliding rod 405. The driven plate 401 is slidably arranged on one side of the breeding tank 101, and one end of the driven plate 401 is fixedly connected to the driven push plate 402. The driven plate 401 is also provided with a driving rack 403. Several of the driven gears 404 are arranged outside the breeding tank 101, and several of the driven gears 404 are coaxially fixedly connected to several of the flow release shells 303. One end of the sliding rod 405 is fixedly connected to the driven push plate 402, and the other end of the sliding rod 405 is elastically slidably inserted into one end of the breeding tank 101.

[0039] In actual application of this embodiment, the driven plate 401 is slidably arranged on one side of the breeding pool 101 along the first direction x, and the driving rack 403 on the driven plate 401 is engaged with a plurality of driven gears 404, so that when the driven plate 401 reciprocates in the first direction x, the driving rack 403 engages and drives the plurality of driven gears 404 to rotate reciprocatingly. Since the driven gear 404 and the plurality of flow release shells 303 are coaxially fixedly connected, the plurality of flow release shells 303 can be driven to rotate reciprocatingly in the xoz plane, ensuring that oxygen is evenly delivered to the bottom of the pool while the residual feed is evenly dispersed to the bottom of the pool.

[0040] See also Figure 3 and Figure 4In a preferred embodiment of the present invention, the Procambarus clarkii breeding pond further comprises a driving member 5, which comprises a driver 501, a first transmission wheel 502, a second transmission wheel 503, a third transmission wheel 504, a rotating arm 505, a driven arm 506, a traction arm 507 and a cam 508. The driver 501 is fixedly arranged on one side of the breeding pond 101, one end of the first transmission wheel 502 is connected to the driver 501 for transmission, and the other end of the first transmission wheel 502 is coaxially equipped with the second transmission wheel 503, and the third transmission wheel 504 is fixedly arranged on the other side of the breeding pond 101. One end of the fixed axis is set on one side of the breeding pool 101, and the other end of the third transmission wheel 504 is connected to the second transmission wheel 503 for transmission. One end of the rotating arm 505 is fixedly connected to the third transmission wheel 504, and the other end of the rotating arm 505 is rotationally connected to the driven arm 506. The end of the driven arm 506 is rotationally connected to the traction arm 507, and the traction arm 507 is slidingly arranged on one side of the reflow pool 102 and fixedly connected to the shaft 202. One end of the cam 508 is coaxially connected to the second transmission wheel 503, and the other end of the cam 508 is movably abutted against the driven push plate 402.

[0041] When the third transmission wheel 504 is rotated, the third transmission wheel 504 is driven to rotate by the rotating arm 505. Since the end of the driven arm 506 is rotatably assembled on the traction arm 507, and the traction arm 507 is slidably arranged on one side of the breeding tank 101 along the first direction x, the traction arm 507 can be driven to reciprocate in the first direction x, so that the shaft 202 fixedly connected to the traction arm 507 can reciprocate synchronously. The cam 508 abuts against the driven push plate 402 during the fixed-axis rotation. Since the driven plate 401 is elastically slidably inserted into the side of the breeding tank 101 through the sliding rod 405, the driven plate 401 can be pushed to reciprocate in the first direction x.

[0042] The above embodiment of the present invention provides a breeding pond for Procambarus clarkii. By arranging a pump flow assembly 2 and a flow release assembly 3 with a pump flow between the breeding pond 101 and the return pond 102, the aerated circulating water can be returned to the breeding pond, so that the circulating water flows into the breeding pond at a low speed, thereby realizing the circulation of water to evenly increase the dissolved oxygen content at the bottom of the pond, and evenly distribute the residual feed to the bottom of the pond, thereby reducing the accumulation and rotting of the feed.
