Description

Technical Field

[0001] The invention relates to the technical field of fish fry proliferation and release, and in particular to a buffer device for fish fry proliferation and release, which is capable of preventing the fish fry from being damaged. Background Art

[0002] Fish fry enhancement and release refers to the release of artificially cultivated or naturally caught fish fry into natural waters such as rivers, lakes, and oceans to increase the amount of aquatic biological resources, improve the aquatic ecological environment, and restore fishery resources. Its main purpose includes replenishing fishery resources and maintaining the sustainable development of fisheries. For example, in some sea areas where overfishing has led to the decline of fishery resources, by releasing fish fry, after a period of growth and reproduction, fishery resources are restored, and fishermen can catch more fish. At the same time, enhancement and release can also improve the structure and function of aquatic ecosystems. Some fish occupy a key position in aquatic ecosystems. Their presence can regulate the relationship between aquatic organisms and promote the ecological balance of aquatic waters.

At the same time, when the scraper cleans the inner wall of the main body, when the scraper contacts the inner wall of the main body for cleaning, the extrusion force between the scraper and the residue on the inner wall of the main body is greater than the tensile force of the sixth spring, so that the scraper moves in the inner side of the sliding groove through the sliding rod, thereby preventing the extrusion force between the scraper and impurities attached to the inner wall of the main body from being too large, thereby causing friction damage to the scraper and the inner wall of the main body.

[0016] 1. The present invention provides a buffer component, and the fry are placed on the top of the buffer shell from the inside of the transport compartment through an external delivery pipe or a discharge trough, so that the fry in the compartment enters the buffer shell through the discharge trough or pipe.

[0017] 2. The present invention places the fry in front of the main body by setting a connecting component, and turns on the water pump to draw river water into the main body through the connecting pipe, so that the fry are fully soaked before being released into the river water, so that the fry can adapt to the water temperature, water quality and other environmental conditions of the water area. At the same time, when the water flow is continuously extracted, a water outlet pipe is provided on the inner side of the main body. When the external water source that follows the fry into the main body is mixed with the river water in the main body, it can be discharged through the water outlet pipe. At the same time, the height of the water outlet pipe is higher than the river water. When the river water is continuously extracted, the water flow entering the main body is slowly discharged at the same time. Since the river water is usually flowing, the river water in the main body is changed at any time, so that the fry can better adapt to the water quality of the river water before being released.

[0018] 3. The present invention provides a discharge component. When river water continuously enters the inner cavity of the main body through the connecting pipe, when the extrusion force of the weight of the river water stored in the main body on the baffle is greater than the tensile force of the fifth spring on the baffle, the baffle continues to move downward in the inner cavity of the discharge shell, thereby causing the baffle to separate from the discharge shell, so that the fry in the main body flows out through the gap formed by the baffle and the discharge shell. At the same time, when the baffle moves downward, the baffle drives the cleaning mechanism to move downward through the connecting rod, so that the cleaning mechanism cleans the inner side of the main body.

[0019] 4. The present invention sets a scraper assembly. When the baffle moves downward by the weight of the water flow, the baffle drives the cleaning frame to move downward on the inner side of the main body through the connecting rod, so that the scraper cleans the inner side of the main body, thereby preventing mud and algae in the river water from remaining on the inner wall of the main body. At the same time, when the scraper cleans the inner wall of the main body, when the scraper contacts the inner wall of the main body for cleaning, the extrusion force between the scraper and the residue on the inner wall of the main body is greater than the tensile force of the sixth spring, so that the scraper moves on the inner side of the sliding groove through the sliding rod, thereby avoiding excessive extrusion force between the scraper and impurities attached to the inner wall of the main body, which will cause friction damage to the scraper and the inner wall of the main body.

Since the river water is usually flowing, the river water in the main body 1 is changed at any time, so that the fry can better adapt to the water quality of the river water before being released. At the same time, when the river water is pumped, impurities in the river water are prevented from being brought into the main body 1. By providing a mesh plate 46 at the bottom of the connecting pipe 41, the mesh plate 46 filters the river water entering the main body 1. At the same time, when the water pump 42 is working, when the river water is pumped, the connecting frame 48 is subjected to the pumping force of the water pump 42, so that the connecting frame 48 is driven by the connecting shaft 47 to move to the side away from the mesh plate 46.

[0045] Example 3: Use Figure 7-Figure 9 The present invention provides a buffer device for preventing fish fry from being damaged and used for proliferation and release as described below.

[0046] like Figure 7-Figure 9 The present invention provides a buffer device for preventing fish fry from being damaged, based on the first embodiment;

[0047] The discharge component 5 includes a connecting rod 51 and a discharge shell 52. The side of the connecting rod 51 is slidably connected to the inner side of the water hole 45. The top of the connecting rod 51 is fixedly connected to the bottom of the cleaning frame 561. The top of the connecting rod 51 is fixedly connected to the cleaning mechanism 56. The bottom of the connecting rod 51 is fixedly connected to the baffle 53. The side of the baffle 53 is provided with a groove 54. The connecting rod 51 is sleeved with a fifth spring 55. The top of the fifth spring 55 is fixedly connected to the bottom of the cleaning frame 561. The bottom of the fifth spring 55 is fixedly connected to the side of the water outlet pipe 43. The top of the discharge shell 52 is fixedly connected to the inner side of the main body 1. When the river water passes through After the connecting tube 41 continues to enter the inner cavity of the main body 1, when the extrusion force of the weight of the river water stored in the main body 1 on the baffle 53 is greater than the tensile force of the fifth spring 55 on the baffle 53, the baffle 53 continues to move downward in the inner cavity of the discharge housing 52, thereby separating the baffle 53 from the discharge housing 52, allowing the fry in the main body 1 to flow out through the gap formed by the baffle 53 and the discharge housing 52. At the same time, when the baffle 53 moves downward, it drives the cleaning mechanism 56 to move downward through the connecting rod 51, so that the cleaning mechanism 56 cleans the inner side of the main body 1.

When the baffle 53 moves downward due to the weight of the water flow, the baffle 53 drives the cleaning frame 561 to move downward inside the main body 1 through the connecting rod 51. Thereby, the scraper 5642 cleans the inner side of the main body 1, thereby preventing the mud and algae in the river water from remaining on the inner wall of the main body 1. At the same time, when the scraper 5642 cleans the inner wall of the main body 1, when the scraper 5642 contacts the inner wall of the main body 1 for cleaning, the extrusion force between the scraper 5642 and the residue on the inner wall of the main body 1 is greater than the tensile force of the sixth spring 5643, so that the scraper 5642 moves on the inner side of the sliding groove 562 through the sliding rod 5641, thereby avoiding excessive extrusion force between the scraper 5642 and impurities attached to the inner wall of the main body 1, which will cause friction damage to the scraper 5642 and the inner wall of the main body 1.

[0050] The specific workflow is as follows:

[0051] During operation, the main body 1 is supported in the water by the supporting component 2, thereby preventing the main body 1 from shaking due to the turbulent river water. By opening the connecting component 4, water in the pond is pumped into the main body 1 through the connecting component 4, and the fry enter the main body 1 through the buffer component 3. When the water volume in the main body 1 reaches a certain weight, the fry in the main body 1 are released through the releasing component 5.

[0052] The device is placed in the river water, and the main body 1 is supported by the support plate 24. When the river water impacts the main body 1, the support shaft 22 slides in the support rod 21, and the first spring 25 acts as a buffer, thereby preventing the river water from impacting the main body 1. This prevents the river water from impacting the main body 1 in windy weather, which may cause turbulent water flow and affect the release effect of fry.

[0053] The fry are placed on the top of the buffer shell 31 from the inside of the transport compartment through an external delivery pipe or a discharge trough, so that the fry in the compartment enters the buffer shell 31 through the discharge trough or pipe. At the same time, the fry and the water flow discharged with the fry impact the spiral blade 34, and at the same time, the fry entering the buffer shell 31 can slide into the inner cavity of the main body 1 through the curvature of the spiral blade 34, thereby avoiding the impact and damage caused by directly dumping the fry. When the fry and the water flow impact the spiral blade 34, the spiral blade 34 drives the buffer frame 32 to move downward through the buffer shaft 33, and at the same time, the second spring 36 works to buffer the impact force between the fry and the spiral blade 34.

[0054] The fry are placed in front of the main body 1, and the river water is pumped into the main body 1 through the connecting pipe 41 by turning on the water pump 42, so that the fry are fully soaked before being released into the river water, so that the fry can adapt to the water temperature, water quality and other environmental conditions of the water area. At the same time, when the water flow is continuously extracted, an outlet pipe 43 is provided on the inner side of the main body 1. When the external water source that follows the fry into the main body 1 is mixed with the river water in the main body 1, it can be discharged through the outlet pipe 43. At the same time, the height of the outlet pipe 43 is higher than the river water. When the river water is continuously extracted, the water flow entering the main body 1 is slowly Slow discharge: Since river water is usually flowing, the river water in the main body 1 is changed at any time, so that the fry can better adapt to the water quality of the river water before being released. At the same time, when the river water is extracted, impurities in the river water are prevented from being brought into the main body 1. A mesh plate 46 is provided at the bottom of the connecting pipe 41, so that the mesh plate 46 filters the river water entering the main body 1. At the same time, when the water pump 42 is working, when the river water is extracted, the connecting frame 48 is subjected to the extraction force of the water pump 42, so that the connecting frame 48 is driven by the connecting shaft 47 to move to the side away from the mesh plate 46;

[0055] When the extraction work is completed and the water pump 42 stops working, the connecting frame 48 is pulled by the reset of the third spring 410, so that the connecting frame 48 moves toward the mesh plate 46 through the connecting shaft 47, so that the extrusion rod 491 ejects the impurities stuck in the mesh of the mesh plate 46 through the ejection block 495. At the same time, when the extrusion force between the ejection block 495 and the impurities stuck in the mesh of the mesh plate 46 is greater than the tensile force of the fourth spring 496, the extrusion rod 491 drives the slider 493 through the sliding rod 494 to slide in the slot 492. At the same time, the buffering work of the fourth spring 496 prevents the extrusion force between the ejection block 495 and the impurities stuck in the mesh from being too large, which will cause extrusion damage to the ejection block 495.

[0056] When river water continuously enters the inner cavity of the main body 1 through the connecting pipe 41, when the squeezing force of the weight of the river water stored in the main body 1 on the baffle 53 is greater than the tensile force of the fifth spring 55 on the baffle 53, the baffle 53 continues to move downward in the inner cavity of the discharge housing 52, thereby separating the baffle 53 from the discharge housing 52, so that the fry in the main body 1 flow out through the gap formed by the baffle 53 and the discharge housing 52. At the same time, when the baffle 53 moves downward, it drives the cleaning mechanism 56 to move downward through the connecting rod 51, so that the cleaning mechanism 56 cleans the inner side of the main body 1.

[0057] When the baffle 53 moves downward due to the weight of the water flow, the baffle 53 drives the cleaning frame 561 to move downward on the inner side of the main body 1 through the connecting rod 51, so that the scraper 5642 cleans the inner side of the main body 1, thereby preventing mud and algae in the river water from remaining on the inner wall of the main body 1. At the same time, when the scraper 5642 cleans the inner wall of the main body 1, when the scraper 5642 contacts the inner wall of the main body 1 for cleaning, the extrusion force between the scraper 5642 and the residue on the inner wall of the main body 1 is greater than the tensile force of the sixth spring 5643, so that the scraper 5642 moves on the inner side of the sliding groove 562 through the sliding rod 5641, thereby avoiding excessive extrusion force between the scraper 5642 and impurities attached to the inner wall of the main body 1, which will cause friction damage to the scraper 5642 and the inner wall of the main body 1.
