[0002] In the prior art, a culture platform is arranged on a water area, a culture box is arranged in the center of the culture platform and is communicated with the water area, fry is placed in the culture box for culture, and the water in the culture box is driven to flow by the flowing water of the water area to exchange water quality and substances, and the water flow can also carry away residual bait and part of excrement to help purify the water in the culture box. At present, the flow water culture needs to regulate the flow rate of the water body to some extent. If the water flow is too fast, the physical consumption of the fish will be accelerated, which is easy to cause the death of the fry and is not conducive to the culture of the fry. SUMMARY

[0003] Therefore, the present application provides a culture box capable of adjusting the flow rate of water in the box. When the flow rate of the external water body is low, the water in the culture box and the external water body can be communicated with each other to exchange water quality. When the flow rate of the external water body is high, the culture box and the external water body are disconnected to protect the fry.

[0004] The technical scheme of the present application is as follows:

[0005] The present application provides a culture box capable of adjusting the flow rate of water in the box, which comprises a culture box body, a plurality of water inlet channels are formed in the inner side wall of the culture box, an adjusting sleeve is slidably arranged in the water inlet channel, a water inlet groove is formed in the front end of the adjusting sleeve and communicated with the water inlet channel, a plurality of water inlet holes are formed in the rear end of the water inlet groove, a plurality of water permeable holes are formed in the inner side wall of the culture box and communicated with the water inlet channel, the water inlet holes and the water permeable holes are staggered, the water on the outer side of the culture box flows through the front end of the water inlet channel, the water inlet groove, the water inlet hole, the rear end of the water inlet channel, the water permeable hole and the inner side of the culture box in sequence, when the adjusting sleeve is slid backward under the impact of the water flow and abuts against the rear end of the water inlet channel, the water permeable hole is blocked by the adjusting sleeve, and an elastic reset mechanism is arranged in the water inlet channel to drive the adjusting sleeve to move forward.

[0006] Preferably, the adjusting sleeve is a "convex" structure with a wide part in the front half and a narrow part in the rear half, the water inlet groove is arranged in the wide part, and the water inlet hole is arranged in the narrow part.

[0007] Preferably, the elastic reset mechanism is a reset spring, the reset spring is sleeved on the outer side of the narrow part, the front end of the reset spring abuts against the back surface of the wide part, and the rear end of the reset spring abuts against the inner end of the water inlet channel.

[0008] Preferably, the inner wall of the water inlet channel is provided with a guide tooth in the axial direction, the outer wall of the wide part of the adjusting sleeve is provided with a guide groove in the axial direction, and the adjusting sleeve is connected with the inner wall of the water inlet channel through the guide groove and the guide tooth.

[0009] Preferably, the front end of the water inlet channel is provided with a limiting ring for preventing the adjusting sleeve from falling out, and the limiting ring is fixedly connected with the inner wall of the front end of the water inlet channel.

[0013] The present application provides a breeding tank capable of adjusting the flow rate of water in the tank. The water in the tank and the water in the external water area flow into each other to facilitate water quality exchange, nutrient exchange, etc. Under normal conditions, the elastic return mechanism keeps the front end of the adjusting sleeve abutting against the front end of the water inlet channel, and the external water can enter the breeding tank through the water inlet hole and the water permeable hole. When the flow rate of the water exceeds a certain value, the adjusting sleeve will slide backward along the water inlet channel until the rear end of the adjusting sleeve abuts against the rear end of the water inlet channel, at which time the water permeable hole is closed, thereby blocking the water in the breeding tank from the outside, preventing high-speed water flow from entering the breeding tank and affecting the growth of the fry. Each water inlet channel of the device works independently, and the flow rates of the water on different sides of the breeding tank are not completely the same. When the flow rate of the water at a certain position is too large, the water flow channel at that position can be closed alone, and the remaining positions with slower flow rates are not affected, which greatly improves the rapid adjustment of the device to complex water environments and better and faster adjusts the flow rate of the water entering the breeding net cage.

DETAILED DESCRIPTION

[0023] In order to better understand the technical content of the present application, the specific embodiments are provided below, and the present application is further described in combination with the drawings.

[0024] Embodiment one

[0025] Referring to Figures 1 to 5 The present application provides a breeding tank capable of adjusting the flow rate of water in the tank, which comprises a breeding tank 1 body with an open top, a plurality of water inlet channels 2 are formed in the inner side wall of the breeding tank 1, an adjusting sleeve 3 is slidably arranged in the water inlet channel 2, a water inlet groove 4 is formed in the front end of the adjusting sleeve 3 and communicates with the water inlet channel 2, a plurality of water inlet holes 5 are formed in the rear end of the water inlet groove 4, a plurality of water permeable holes 6 are formed in the inner side wall of the breeding tank 1 and communicate with the water inlet channel 2, the water inlet holes 5 and the water permeable holes 6 are staggered, water on the outer side of the breeding tank 1 flows through the front end of the water inlet channel 2, the water inlet groove 4, the water inlet hole 5, the rear end of the water inlet channel 2, the water permeable hole 6 and the inner side of the breeding tank 1 in sequence, when the adjusting sleeve 3 is slid backward under the impact of water flow and abuts against the rear end of the water inlet channel 2, the water permeable hole 6 is blocked by the adjusting sleeve 3, and an elastic reset mechanism is arranged in the water inlet channel 2 to drive the adjusting sleeve 3 to move forward.

[0026] The breeding tank 1 is placed in the breeding water area, and the fry is bred in the breeding tank 1, and the water in the breeding tank 1 and the water in the external water area flow into each other to facilitate water quality exchange, nutrient exchange and the like. In the conventional state, the elastic reset mechanism pushes the adjusting sleeve 3 to slide outward, and the front end of the adjusting sleeve 3 abuts against the front end of the water inlet channel 2. When the external water flows into the breeding tank 1, the water flows into the water inlet groove 4 of the adjusting sleeve 3 from the water inlet channel 2, and then the water continues to flow inward from the water inlet hole 5 at the tail of the adjusting sleeve 3, enters the rear half of the water inlet channel 2, and finally flows into the breeding tank 1 through the water permeable hole 6. The reverse is also true. When the water body flows, the water inlet groove 4 will be subjected to an impact force of the water body, thereby exerting a backward thrust on the adjusting sleeve 3. The greater the flow rate of the water body, the greater the thrust on the adjusting sleeve 3. Since the elastic reset mechanism is provided, when the thrust is less than the elastic force exerted by the elastic reset mechanism on the adjusting sleeve 3, the adjusting sleeve 3 remains in a stationary state. When the flow rate of the water body exceeds a certain value, i.e. the thrust is greater than the elastic force of the elastic reset mechanism, the adjusting sleeve 3 will slide backward along the water inlet channel 2 until the rear end of the adjusting sleeve 3 abuts against the rear end of the water inlet channel 2. At this time, the water permeable hole 6 is blocked by the adjusting sleeve 3, and the staggered water inlet holes 5 and water permeable holes 6 cannot form a communicating flow channel, thereby blocking the water body outside the breeding tank 1, preventing high-speed water flow from entering the breeding tank 1, and affecting the growth of the fry. When the flow rate of the water body slows down, the thrust on the adjusting sleeve 3 is less than the elastic force, and the elastic reset mechanism pushes the adjusting sleeve 3 to slide outward to reset, thereby reopening the water flow channel between the inside and outside of the breeding tank 1, and the breeding tank 1 renews the water quality exchange and material exchange with the external water area. Each water inlet channel 2 of the device works independently, can be arranged on the opposite two sides of the breeding tank 1, or can be arranged on multiple sides of the breeding tank 1. Since the flow direction of the water body in the water area varies, the flow rate of the water body on different sides of the breeding tank 1 is not completely the same. Through completely independent water inlet channels 2, when the flow rate of the water body at a certain position is too large, the water flow channel at that position can be closed alone, and the remaining positions with slower flow rate are not affected, which greatly improves the rapid adjustment of the device to the complex environment of the water area. Under the action of the thrust of the water flow, the adjusting sleeve 3 can quickly respond, and through the cooperation of the monitoring elements such as the water flow sensor and the controller and the flow channel closing device, a certain time delay reaction will be generated. Therefore, the device can better and faster adjust the flow rate of the water body entering the breeding net cage.

[0027] The adjusting sleeve 3 is a "convex" structure with a wide portion 7 in the front half and a narrow portion 8 in the rear half. The water inlet groove 4 is arranged in the wide portion 7, and the water inlet hole 5 is arranged in the narrow portion 8. The water inlet groove 4 communicates with the rear half of the water inlet channel 2 through the water inlet hole 5.

[0028] The elastic reset mechanism is a reset spring 9, the reset spring 9 is sleeved on the outside of the narrow part 8, the front end of the reset spring 9 abuts against the back of the wide part 7, and the rear end of the reset spring 9 abuts against the inner end of the water inlet channel 2. The reset spring 9 applies a forward elastic force to the adjusting sleeve 3, when the adjusting sleeve 3 is flushed to the rear end, and after the water flow gradually slows down, the reset spring 9 can also play a role in resetting the forward movement of the adjusting sleeve 3.

[0029] The inner wall of the water inlet channel 2 is provided with a guide tooth 10 in the axial direction, and the outer wall of the wide part 7 of the adjusting sleeve 3 is provided with a guide groove 11 in the axial direction, and the adjusting sleeve 3 is slidably connected with the inner wall of the water inlet channel 2 through the guide groove 11 and the guide tooth 10. The guide tooth 10 and the guide groove 11 ensure that the adjusting sleeve 3 does not rotate, and ensure that the water inlet hole 5 and the water permeable hole 6 always maintain an interleaved positional relationship, so that the water permeable hole 6 can be closed when the adjusting sleeve 3 moves to the rightmost end.

[0030] The front end of the water inlet channel 2 is provided with a limiting ring 12 for preventing the adjusting sleeve 3 from falling out, and the limiting ring 12 is fixedly connected with the inner wall of the front end of the water inlet channel 2.

[0031] Embodiment two

[0032] See Figures 6 to 7 The difference between the present embodiment and embodiment one is that the inner side wall of the breeding tank 1 is provided with a mounting groove 13, the rear end of the water inlet channel 2 communicates with the mounting groove 13, a fixed plate 14 for shielding the rear end of the water inlet channel 2 is mounted in the mounting groove 13, the fixed plate 14 is detachably connected with the mounting groove 13, and the water permeable hole 6 is formed in the fixed plate 14.

[0033] The fixed plate 14 is detachably connected with the mounting groove 13 by bolts, and the fixed plate 14 is flush with the inner side wall of the breeding tank 1 after being mounted.

[0034] The elastic force of the reset spring 9 itself is related to the material, overall length and thickness of the spring. After the fixed plate 14 is detached from the inner side of the breeding tank 1, the outlet at the rear end of the water inlet channel 2 can be seen, which facilitates the mounting and dismounting of the reset spring 9. When a reset spring 9 with smaller elastic force is replaced, a water flow with smaller flow rate can push the adjusting sleeve 3 to move, and when a reset spring 9 with larger elastic force is replaced, a water flow with larger flow rate is needed to push the adjusting sleeve 3 to move. Therefore, the elastic force of the reset spring 9 can be adjusted by replacing it, so as to adjust the movement threshold of the adjusting sleeve 3, and then set the flow rate limit value for triggering the movement of the adjusting sleeve 3. The test method of the elastic force of the spring will not be described in detail, and it can be completed according to the prior art. After replacement, the fixed plate 14 can be mounted back to the inner wall of the breeding tank 1.

[0035] The above merely provides the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
