Description

Technical Field

[0001] This utility model relates to the field of oxygen-providing fish fry transport boxes, specifically an oxygen-providing fish fry transport box. Background Technology

[0002] Fish fry transportation is a crucial part of aquaculture operations. Because fish fry are small, weak, and have poor disease resistance, they are prone to death or injury during transportation. The main cause of death during transportation is stress. Therefore, to ensure the survival rate of fish fry during transportation, it is necessary to reduce the impact of bumps during transportation.

[0003] In the prior art, such as in publication number CN215422333U, an oxygen-supplied fish fry transport box for fish fry breeding is disclosed. It includes a transport box body, with four sets of self-locking casters evenly distributed at the lower end of the transport box body. Two sets of horizontal plates are symmetrically arranged inside the transport box body. Shock-absorbing components are provided at the upper end of the two sets of horizontal plates. A fish fry box is provided above the shock-absorbing components. An oxygenator is provided on one side of the transport box body. The oxygenator is equipped with multiple sets of oxygen supply pipes located inside the fish fry box. A box door is hinged to the other side of the transport box body. By setting a first spring and a second spring, the vertical and horizontal displacement of the fish fry box is reduced, the water sloshing inside the fish fry box is reduced, and the stress response of the fish fry is reduced, thereby improving the survival rate of fish fry during transport.

[0004] While the aforementioned patent facilitates movement of the device by incorporating self-locking casters and a push rod frame, the vibrations generated during movement are transmitted to the oxygen supply structure. Over time, this can damage the internal hardware of the oxygen supply structure. Furthermore, repairing an accidentally damaged oxygen supply structure during transportation is not feasible, as it cannot be quickly disassembled for the installation of a new one. Therefore, to address these issues, an oxygen-supplying fish fry transport box is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, vibrations generated during movement are transmitted to the oxygen supply structure, which over time can damage the internal hardware structure. Furthermore, repairing an accidentally damaged oxygen supply structure during transportation is not feasible, as it cannot be quickly disassembled for the installation of a new oxygen supply structure. Therefore, this invention proposes an oxygen-supplying fish fry transport box.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides an oxygen-supplied fish fry transport box, including a transport box, a connecting component fixedly connected to the inner side wall of the transport box, an oxygen supply device provided on the side of the connecting component, a buffer structure fixedly connected to the bottom surface of the transport box in an axisymmetric manner, universal wheels fixedly connected to the bottom surface of the buffer structure, and a protective cover covering the buffer structure fixedly connected to the bottom surface of the transport box.

[0007] The connecting assembly includes a limiting plate fixedly connected to the inner side wall of the transport box. A positive and negative screw rod is rotatably connected inside the limiting plate. The two ends of the positive and negative screw rod are threadedly connected to movable blocks that can move in opposite directions. A rubber pad is embedded in the side groove of the movable block. One end of the positive and negative screw rod extends out of the limiting plate and is fixedly connected to a handle.

[0008] The buffer structure includes side plates symmetrically fixedly connected to the bottom of the transport box, a sliding rod fixedly connected between the two side plates, sliders slidably connected to both ends of the sliding rod, a hydraulic buffer rod connected to the slider on the side of the side plate, a clamping plate rotatably connected to the bottom surface of the slider through a connecting rod, a spring sleeved on the surface of the sliding rod between the two sliders, and a universal wheel fixedly installed on the bottom surface of the clamping plate.

[0009] Preferably, the positive and negative lead screws are driven by a rotating handle to slide two moving blocks towards each other along the surface of the positive and negative lead screws, and the rubber pads clamp and fix the side of the oxygen supply equipment.

[0010] Preferably, the two ends of the spring abut against the opposite sides of the two sliders, and one end of the hydraulic buffer rod is fixed to the side of the side plate and the other end is connected to the slider.

[0011] Preferably, the protective cover is a U-shaped cover with an opening at the bottom, and its top edge is welded and fixed to the bottom surface of the transport box, with the opening completely covering the buffer structure.

[0012] Preferably, the oxygen supply device is fixed to the inner side wall of the transport box by a movable block of the connecting component and a rubber pad.

[0013] Preferably, the clamping plate is fixedly connected to the wheel frame of the omnidirectional wheel by bolts.

[0014] The advantages of this utility model are:

[0015] 1. This utility model, through the structural design of the hydraulic buffer rod and spring in the buffer structure, when the caster wheel encounters bumps, the connecting rod pushes the slider to slide along the slide rod to compress the spring, and at the same time the hydraulic buffer rod absorbs the vibration energy, realizing the function of multi-level shock absorption, solving the problem of damage to internal components of oxygen supply equipment caused by long-term vibration, and effectively reducing the vibration amplitude of the transport box;

[0016] 2. This utility model uses a connecting component with positive and negative screws to drive the moving blocks on both sides to move in opposite directions. The structure design of the oxygen supply equipment is achieved by using rubber pads to elastically clamp the oxygen supply equipment, which realizes the function of quickly completing the disassembly and assembly of the oxygen supply equipment. In case of equipment failure during transportation, it can be replaced immediately, which significantly improves maintenance efficiency. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4As shown, an oxygen-supplied fish fry transport box includes a transport box 1. A connecting component 2 is fixedly connected to the inner side wall of the transport box 1. An oxygen supply device 3 is provided on the side of the connecting component 2. A buffer structure 4 is fixedly connected to the bottom surface of the transport box 1 in an axisymmetric manner. A caster wheel 5 is fixedly connected to the bottom surface of the buffer structure 4. A protective cover 6 covering the buffer structure 4 is fixedly connected to the bottom surface of the transport box 1. The connecting component 2 includes a limiting plate 21 fixedly connected to the inner side wall of the transport box 1. A positive and negative screw rod 22 is rotatably connected inside the limiting plate 21. The two ends of the positive and negative screw rod 22 are threadedly connected to movable blocks 23 that can move in opposite directions. A rubber pad 24 is embedded in the groove on the side of the movable block 23. One end of the positive and negative screw rod 22 extends out of the limiting plate 21 and is fixedly connected to a handle 25.

[0025] During operation, the specific implementation of the connecting component 2 is as follows: The limiting plate 21 welded to the inner side wall of the transport box 1 is equipped with a positive and negative screw rod 22 through a bearing. The threaded sections at both ends of the positive and negative screw rod 22 with opposite directions of rotation respectively engage with two moving blocks 23. A rubber pad 24 with a Shore hardness of 60±5 is bonded to the rectangular groove on the side of the moving block 23. The end of the positive and negative screw rod 22 passes through the limiting plate 21 and is welded with a hexagonal handle 25. When the handle 25 is rotated, the positive and negative screw rod 22 drives the two moving blocks 23 to move towards each other along the guide groove of the limiting plate 21. A small micro air pump of model HIBLOW HP-20 is clamped and fixed by the rubber pad 24 as an oxygen supply device 3. The oxygen delivery hose of the air pump passes through the side wall of the transport box 1 and extends into the water inside the box.

[0026] Furthermore, the buffer structure 4 includes side plates 41 symmetrically fixedly connected to the bottom surface of the transport box 1, a slide rod 42 fixedly connected between the two side plates 41, a slider 43 slidably connected to both ends of the slide rod 42, a hydraulic buffer rod 44 connected to the slider 43 on the side of the side plate 41, a clamping plate 46 rotatably connected to the bottom surface of the slider 43 through a connecting rod 45, a spring 47 sleeved on the surface of the slide rod 42 between the two sliders 43, and a universal wheel 5 fixedly installed on the bottom surface of the clamping plate 46;

[0027] During operation, a sliding rod 42 is horizontally fixed between the side plates 41 symmetrically welded to the bottom of the transport box 1. Sliding blocks 43 are slidably mounted at both ends of the sliding rod 42. The bottom surface of the sliding block 43 is hinged to a connecting rod 45 via a pin. The bottom end of the connecting rod 45 is hinged to the top surface of the clamping plate 46. The bottom surface of the clamping plate 46 is fixedly mounted with a universal wheel 5 via bolts. The spring 47 sleeved on the surface of the sliding rod 42 abuts against the opposite sides of the two sliding blocks 43 at both ends. A hydraulic buffer rod 44 is installed in a rectangular array on the outside of the side plate 41. One end is welded to the surface of the side plate 41, and the other end is connected to the side of the sliding block 43 via a ball joint. When the universal wheel 5 is subjected to bumps and impacts, the clamping plate 46 pushes the sliding block 43 along the sliding rod 42 to compress the spring 47 via the connecting rod 45. At the same time, the damping piston of the hydraulic buffer rod 44 contracts to buffer the vibration.

[0028] Furthermore, the two ends of the spring 47 abut against the opposite sides of the two sliders 43 respectively, and one end of the hydraulic buffer rod 44 is fixed to the side of the side plate 41 and the other end is connected to the slider 43.

[0029] During operation, the spring 47 is sleeved on the surface of the slide rod 42 and located between the two sliders 43. Its two ends abut against the opposite sides of the two sliders 43 respectively. The other end of the hydraulic buffer rod 44 welded to the side of the side plate 41 is connected to the outer side of the slider 43 through a hinge seat. When the caster wheel 5 is subjected to bumps and impacts, the connecting rod 45 pushes the slider 43 to slide along the slide rod 42 to compress the spring 47. At the same time, the damping piston of the hydraulic buffer rod 44 generates reverse resistance as the slider 43 moves, forming a dual shock absorption mechanism of spring elastic buffer and hydraulic damping shock absorption. This effectively reduces the vertical and horizontal vibration of the transport box 1, avoids wear of the air pump impeller or loosening of the pipeline caused by severe vibration of the oxygen supply equipment 3, and significantly improves the transport stability and service life of the equipment.

[0030] Furthermore, the protective cover 6 is a U-shaped cover with an opening at the bottom, and its top edge is welded and fixed to the bottom surface of the transport box 1, with the opening completely covering the buffer structure 4;

[0031] During operation, the protective cover 6 is formed by bending a U-shaped steel plate. Its top edge is fixed to the bottom surface of the transport box 1 by continuous welding. The bottom opening completely covers the side plate 41, slide bar 42 and hydraulic buffer bar 44 of the buffer structure 4. The bottom edge of the opening maintains a distance of 10-15mm from the top of the caster wheel 5. This structure isolates the buffer structure 4 from external mud and water stains through a rigid cover, and prevents branches or gravel from hitting the hydraulic buffer bar 44 and spring 47 during transportation. At the same time, the bottom opening design avoids interfering with the steering and shock absorption stroke of the caster wheel 5, taking into account both the protective performance and the functional integrity of the buffer structure 4, and extending the maintenance cycle of the shock absorption system.

[0032] Working principle: When the transport box 1 moves, the bumps and impacts encountered by the casters 5 are transmitted to the connecting rod 45 through the clamping plate 46, driving the slider 43 to slide along the slide rod 42 to compress the spring 47. At the same time, the damping piston of the hydraulic buffer rod 44 generates reverse resistance, forming a shock absorption effect of elastic deformation of the spring 47 and hydraulic damping, which greatly reduces the vibration amplitude of the transport box 1. The rotating handle 25 in the connecting assembly 2 drives the positive and negative lead screws 22 to rotate, so that the two moving blocks 23 move towards each other along the guide groove of the limiting plate 21. The oxygen supply equipment 3 is elastically clamped and fixed by the rubber pad 24 to prevent the equipment from shifting or falling off during the shock absorption process. The protective cover 6 isolates external pollutants from entering the buffer structure 4 through the welded U-shaped cover, ensuring that the shock absorption operation of the slide rod 42, spring 47 and hydraulic buffer rod 44 is not disturbed by the outside, maintaining the stable oxygen supply and long-term shock absorption performance of the transport box 1.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
