Description

Technical Field

[0001] This utility model belongs to the technical field of aquaculture equipment, specifically relating to a device for preventing fish from jumping and getting injured during fish transportation. Background Technology

[0002] In the aquaculture industry, fish transportation (such as inter-regional transport of fry, sales and distribution of adult fish, and separate rearing between ponds) is a crucial link between aquaculture and sales, and its efficiency and fish survival rate directly affect the economic benefits of aquaculture. Currently, the industry commonly uses traditional containers such as ordinary plastic buckets, open metal boxes, or simple canvas pools for fish transportation. These devices lack or are inefficient in preventing jumping.

[0003] Fish are prone to stress during transport due to factors such as vehicle jolting, water quality fluctuations, and unfamiliar environments, leading to frequent jumping behavior. Traditional open containers cannot prevent fish from jumping out, causing them to fall to the ground and die or be seriously injured. Some covered containers use a fully enclosed structure, which is not only inconvenient to operate but also prone to insufficient dissolved oxygen. Furthermore, when fish jump, they still violently impact the cover, causing damage to their body surface, loss of scales, and increasing the risk of infection. Utility Model Content

[0004] The purpose of this invention is to provide a device for preventing fish from jumping and getting injured during fish transport, in order to solve the problems of lack of or inefficiency in the anti-jump protection of existing fish transport equipment mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for preventing fish from jumping and getting injured during fish transport, comprising a fish container and a positioning sleeve fixed to the lower half of the fish container. Multiple flow guide holes are provided around the fish container and on its bottom plate. Positioning posts are fixed at the four corners of the bottom of the positioning sleeve. A support sleeve is fixed to the outer wall of the upper half of the fish container. A limit cover is movably connected to the outer wall of the support sleeve, and a protective net is movably connected inside the limit cover. A limit sleeve is provided at the bottom of the protective net and movably connected to the limit cover. Two fixing mechanisms are symmetrically arranged on the limit cover. The protective net has an open structure at both the top and bottom. A limit rope is provided at the upper edge of the protective net, and a limit mechanism is movably connected to the outside of the limit rope.

[0006] In a further embodiment, the fixing mechanism consists of a guide plate and a fixing pin. The outer walls of both sides of the limiting cover are provided with grooves to accommodate the guide plate. The fixing pin is fixedly connected to the guide plate and extends into the limiting cover. A fixing ring is fixed to the outer wall of the fixing pin.

[0007] In a further embodiment, a fixing spring supporting the fixing ring is sleeved on the outside of the fixing pin, and fixing grooves matching the fixing pin are opened on both outer walls of the limiting sleeve.

[0008] In a further embodiment, the limiting mechanism consists of a limiting buckle and a limiting post. The outer walls on both sides of the limiting buckle and the limiting post are provided with moving holes for the limiting rope to move. The surface of the limiting buckle is provided with a through hole for the limiting post to move.

[0009] In a further embodiment, the bottom of the limiting post is provided with an installation hole, a support spring is fixed in the installation hole, and a limiting ring that is movably connected to the limiting buckle is fixed on the outer wall of the limiting post.

[0010] In a further embodiment, two buckles are fixed to the outer walls of the support sleeve, the inner wall of the limiting cover is provided with a groove that matches the buckles, and the four corners of the support sleeve, the limiting cover and the limiting sleeve are provided with positioning holes that match the positioning posts.

[0011] In a further embodiment, the surface of the limiting sleeve is fixed with a plurality of limiting protrusions, and the limiting cover is provided with a plurality of limiting grooves that match the limiting protrusions.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This device, used to prevent fish from jumping and getting injured during fish transport, features a protective net with openings at both the top and bottom. This not only physically blocks fish from jumping during transport, preventing them from jumping out of the container or hitting the outer wall and causing damage, but also allows for flexible adjustment of the opening size through a limiting mechanism. When loading fish, the opening can be enlarged for quick loading and unloading, while the opening can be locked during transport to prevent jumping, effectively reducing the rate of fish surface injury and mortality.

[0014] The positioning post at the bottom of the positioning sleeve precisely matches the positioning holes of the support sleeve, the limiting cover, and the limiting sleeve, which can achieve stable positioning when multiple devices are stacked vertically, avoiding container slippage and tipping caused by transportation bumps. At the same time, the support sleeve and the limiting cover are connected by a snap and slot structure, which can be quickly disassembled and assembled without tools, and the connection strength is high, which simplifies operation and ensures the overall stability of the device during transportation.

[0015] The fixing mechanism automatically engages the fixing pin with the limiting sleeve via a fixing spring. The limiting sleeve and the protective net can be disassembled and replaced without tools by pulling the guide plate, which makes it easy to adjust the size of the protective net according to the size of the fish and adapt to the transportation needs of different species of fish.

[0016] The limiting protrusion of the limiting sleeve and the limiting groove of the limiting cover can further fix the position of the protective net, prevent the protective net from shifting or being damaged during transportation, and extend the service life of the protective net. This device is used to prevent fish from jumping and getting injured during fish transportation. It can effectively prevent fish from jumping and causing damage during fish transportation, and improve aquaculture efficiency. Attached Figure Description

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] This utility model provides, for example Figure 1-5The device shown is for preventing fish from jumping and getting injured during fish transport. It includes a fish container 1 and a positioning sleeve 2 fixed to the lower half of the fish container 1. Multiple flow guide holes are provided around the fish container 1 and on its bottom plate. Positioning posts 3 are fixed at the four corners of the bottom of the positioning sleeve 2. A support sleeve 4 is fixed to the outer wall of the upper half of the fish container 1. A limit cover 6 is movably connected to the outer wall of the support sleeve 4. Two buckles 5 are fixed to the outer walls of the support sleeve 4. The inner wall of the limit cover 6 has grooves that match the buckles 5, allowing for easy assembly and disassembly of the limit cover 6. A protective net 7 is movably connected inside the limit cover 6. The protective net 7 has an open structure at both the top and bottom, and its bottom is provided with a connection point movably connected to the limit cover 6. The limiting sleeve 8 has multiple limiting protrusions 9 fixed on its surface. The limiting cover 6 has multiple limiting grooves that match the limiting protrusions 9. The limiting protrusions 9 pass through the mesh holes at the bottom of the protective net 7 and are inserted into the limiting grooves, which can fix one end of the protective net 7 to prevent it from falling off. The protective net 7 can prevent fish from jumping and falling and causing damage. The four corners of the support sleeve 4, the limiting cover 6 and the limiting sleeve 8 are all provided with positioning holes that match the positioning posts 3. During transportation, one device is placed on the surface of another device, and the positioning posts 3 are inserted into the positioning holes of the support sleeve 4, the limiting cover 6 and the limiting sleeve 8 to ensure the stability of the two devices stacked, thereby ensuring the stability during transportation.

[0027] Two fixing mechanisms are symmetrically arranged on the limiting cover 6. The fixing mechanism consists of a guide plate 10 and a fixing pin 11. The outer walls of both sides of the limiting cover 6 are provided with grooves to accommodate the guide plate 10. The fixing pin 11 is fixedly connected to the guide plate 10 and extends into the limiting cover 6. A fixing ring 12 is fixed to the outer wall of the fixing pin 11. A fixing spring 13 supporting the fixing ring 12 is sleeved on the outside of the fixing pin 11. The outer walls of both sides of the limiting sleeve 8 are provided with fixing grooves that match the fixing pin 11. The elastic force of the fixing spring 13 can be set according to the actual use requirements. By supporting the fixing ring 12 with the fixing spring 13, the fixing pin 11 is inserted into the fixing groove of the limiting sleeve 8, which can fix the position of the limiting sleeve 8, thereby ensuring the stability of the protective net 7 after installation. By pulling the fixing pin 11 with the guide plate 10, the fixing pin 11 is separated from the limiting sleeve 8, which can quickly remove the limiting sleeve 8 from the limiting cover 6, thereby facilitating the disassembly and replacement of the protective net 7.

[0028] A limiting rope 14 is provided at the upper edge of the protective net 7, and the limiting rope 14 is externally connected to a limiting mechanism. The limiting mechanism consists of a limiting buckle 15 and a limiting post 16. Moving holes for the limiting rope 14 are provided on both outer walls of the limiting buckle 15 and on the limiting post 16. A through hole for the limiting post 16 is provided on the surface of the limiting buckle 15. A mounting hole is provided at the bottom of the limiting post 16, and a support spring 17 is fixed inside the mounting hole. A limiting ring 18, which is movably connected to the limiting buckle 15, is fixed to the outer wall of the limiting post 16. The limiting mechanism is activated by pressing the limiting rope 14. Position post 16 is positioned so that the movable hole on the limiting post 16 and the limiting buckle 15 are on the same horizontal line, which facilitates the movement of the limiting buckle 15 on the limiting rope 14 and adjusts the size of the opening on the protective net 7, making it easy to put fish into or take fish out of the fish container 1. When the limiting post 16 is released, the support spring 17 supports the limiting post 16, causing the limiting buckle 15 and the through hole on the limiting post 16 to be misaligned, thereby fixing the limiting buckle 15 on the limiting rope 14 and locking the size of the opening on the protective net 7 to prevent fish from jumping out of the fish container 1.

[0030] In the description of this utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Working principle:

[0032] This device, used to prevent fish from jumping and getting injured during fish transport, works as follows: When transporting fish, press the limiting post 16 of the limiting mechanism to compress the support spring 17 and move it downward until the limiting post 16 and the moving hole on the limiting buckle 15 are at the same horizontal line. At this time, the limiting buckle 15 can be slid along the limiting rope 14 to adjust the opening size of the upper opening of the protective net 7, so that the fish can be smoothly placed into the fish container 1. After the fish are placed in, release the limiting post 16, and the support spring 17 will reset and push the limiting post 16 upward, so that the limiting post 16 and the moving hole of the limiting buckle 15 are misaligned, thereby locking the position of the limiting buckle 15 and preventing the upper opening of the protective net 7 from being too large and causing the fish to jump out.

[0033] During transportation, if multiple devices need to be stacked, the positioning holes of the upper device's support sleeve 4, limit cover 6, and limit sleeve 8 are aligned with the positioning post 3 at the bottom of the lower device's positioning sleeve 2 and inserted to achieve stable stacking and prevent the devices from sliding and tipping over. The flow hole of the fish container 1 can enable the flow of water to the external environment and maintain the stability of the water quality inside the container.

[0034] After the transfer is completed, pull the guide plates 10 on both sides of the limiting cover 6 to drive the fixing pin 11 to compress the fixing spring 13 and disengage from the fixing groove of the limiting sleeve 8. Then the limiting sleeve 8 and the protective net 7 can be removed, which makes it easier to clean or maintain the fish container 1 and the protective components, and prepare for the next use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
