Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a mobile fish fry cultivation device. Background Technology

[0002] Fish fry rearing is a crucial step in aquaculture. The quality of the rearing environment directly affects the survival rate and growth quality of the fish fry. In the traditional fish fry rearing model, farmers usually use large ponds or tanks for centralized rearing. Although this method is convenient for managing large quantities of fish fry, its drawbacks are also very obvious.

[0003] When it is necessary to manage fish fry of different species, sizes, or growth stages separately, the integrated structure of large rearing ponds makes it difficult to divide the fry into zones. Farmers find it difficult to provide precise feed, control water quality, or prevent diseases for specific groups of fish. In addition, when it is necessary to sort, count, or transfer some fish fry, it must be done in the entire large pond, which is difficult and can easily cause unnecessary stress damage to the fish fry.

[0004] To address this issue, some solutions have emerged in the industry that involve setting up isolation nets or small rearing boxes within large ponds. While these solutions achieve zoning to some extent, the internal units are often structurally simple, making their movement, fixing, and independent water changes extremely inconvenient. Especially when frequent water changes are required, farmers have to drain and add water to each internal unit individually. This process is not only time-consuming and labor-intensive but also lacks unified and efficient management methods, thus hindering the efficiency of large-scale and refined fish fry rearing.

[0005] Therefore, this utility model proposes a mobile fish fry cultivation device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in fish fry cultivation devices, such as the difficulty in independently moving and efficiently operating the internal cultivation units, the difficulty in achieving centralized and rapid water exchange, and the low management efficiency, this utility model aims to provide a mobile fish fry cultivation device with an improved structure that can effectively solve the above problems.

[0009] Furthermore, a fixed frame is fixedly connected to the bottom surface of the cultivation tank, and a cylinder serving as a power source is fixedly connected to the bottom surface of the fixed frame. A connecting frame is fixedly connected to the output shaft end of the cylinder, and a push rod is fixedly connected to the top surface of the connecting frame. The push rod is located below the cultivation chamber and corresponds to the sealing cover. The cylinder is designed to drive the connecting frame and the push rod to move up and down, so that the push rod passes through the drain pipe and abuts against the sealing cover, thereby realizing centralized drainage control of the cultivation chamber.

[0010] Preferably, a sealing strip is provided on the bottom surface of the sealing cover to enhance the sealing performance when the sealing cover abuts against the top surface of the drain pipe.

[0011] Preferably, the movable fish fry cultivation device further includes a fixing sleeve, a locking rod, a spring, and a locking seat.

A spring is elastically connected between the locking rod and the fixing sleeve. A locking seat that engages with the locking rod is fixed on the outer wall of the cultivation chamber. This locking mechanism is used to automatically fix the cultivation chamber after it enters the opening of the chamber.

[0012] In one specific implementation, the spring is sleeved outside the snap-fit ​​rod and elastically connected between the snap-fit ​​rod and the fixing sleeve, providing reliable elastic force for the snap-fit ​​rod to reset.

[0013] Preferably, a loading plate is rotatably connected to one side of the cultivation tank, and directional support wheels are fixed on the loading plate. When opened, this structure can form a stable ramp to assist the cultivation tank in being smoothly loaded into or removed from the opening by relying on its wheels.

[0022] 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 protection scope of the present utility model.

[0023] Please refer to Figures 1 to 4 This utility model provides a mobile fish fry rearing device, which aims to solve the problems of the existing fish fry rearing pond having a single structure, making it difficult to manage different batches of fish fry in different areas, operate independently, and efficiently change water.

[0024] like Figures 1 to 4 As shown, the movable fish fry rearing device includes a rearing pond 1, which serves as the mounting base for the entire device. A partition 2 is fixed inside the rearing pond 1, dividing the interior of the rearing pond 1 into at least two compartments. It also includes a rearing compartment 202, which is movably accommodated within the compartment. Specifically, the bottom of the rearing compartment 202 is fixed with wheels 203, which support the rearing compartment 202.

[0025] A fixing hole 205 is provided at the center of the bottom surface of the cultivation chamber 202. A drain pipe 206 is fixed in the fixing hole 205. A filter cover 208 is slidably inserted in the drain pipe 206. A sealing cover 207 is fixed on the top surface of the filter cover 208. A sealing strip is provided on the bottom surface of the sealing cover 207.

[0026] A fixing frame 401 is fixed to the bottom surface of the cultivation pool 1, a cylinder 402 is fixed to the bottom surface of the fixing frame 401, a connecting frame 4 is fixed to the output shaft end of the cylinder 402, and a push rod 209 is fixed to the top surface of the connecting frame 4.

[0027] The top rod 209 is located below the cultivation chamber 202 and corresponds to the sealing cover 207. The connecting frame 4 is adapted to move upward under the drive of the cylinder 402 so that the top rod 209 passes through the drain pipe 206 and abuts against the sealing cover 207. Through this centralized control mechanism located outside the cultivation tank 1, the control of the drainage valve inside the cultivation chamber 202 is realized.

[0028] The device also includes a fixing sleeve 3, which is fixedly connected to the inner wall of the partition 2 and the inner wall of the cultivation tank 1. The fixing sleeve 3 has an inner cavity for receiving, and a locking rod 302 is slidably disposed inside it. A spring 301 is also elastically connected between the locking rod 302 and the fixing sleeve 3. In this embodiment, the spring 301 is sleeved on the outside of the locking rod 302 and elastically connected between the locking rod 302 and the fixing sleeve 3. The fixing sleeve 3, the locking rod 302, and the spring 301 together constitute a locking structure, which provides an automatic locking mechanism for the cultivation tank 202. Meanwhile, a corresponding mounting bracket 303 is fixedly installed on the outer wall of the incubation chamber 202. In the assembled state, when the walking wheel 203 of the incubation chamber 202 is pushed in along the bottom surface of the chamber opening, the guide slope of the mounting bracket 303 on the incubation chamber 202 will first compress the locking rod 302. When the incubation chamber 202 is pushed into place, the mounting bracket 303 passes over the locking rod 302, and the elastic force stored in the spring 301 pushes the locking rod 302 to reset and lock into the mounting bracket 303, ensuring the accuracy, reliability and ease of installation of the incubation chamber 202 in the chamber opening.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to facilitate loading and unloading of the cultivation chamber 202, a loading plate 201 is rotatably connected to one side of the cultivation pool 1 via a hinge, and a directional support wheel 204 is fixed on the loading plate 201.

[0030] As another preferred embodiment, in order to add water to the cultivation chamber 202, support plates 5 are fixed on the front and rear sides of the cultivation pool 1, spray pipes 501 are fixed between multiple support plates 5, and connecting holes 502 are provided on the support plates 5.

[0031] As a further definition of the locking structure, in one specific embodiment, the spring 301 is sleeved on the outside of the locking rod 302 and elastically connected between the locking rod 302 and the fixing sleeve 3.

[0032] The working principle of this mobile fish fry cultivation device is as follows: When the culture chamber 202 needs to be loaded, the loading plate 201, which is rotatably connected to one side of the culture tank 1, is first opened. The directional support wheel 204 on the loading plate 201 abuts against the ground to form a ramp. Then, the culture chamber 202 is pushed. The walking wheel 203 at the bottom of the culture chamber 202 allows it to be pushed into the chamber opening separated by the partition 2 along the top surface of the loading plate 201. During the pushing process, the card seat 303 on the outer wall of the culture chamber 202 will first compress the locking rod 302 in the fixing sleeve 3. When the culture chamber 202 is fully pushed into place, the spring 301 pushes the locking rod 302 to reset and lock into the card seat 303, thereby realizing the rapid positioning and locking of the culture chamber 202.

[0033] When it is necessary to change the water in the rearing chamber 202, the cylinder 402, which is fixed on the bottom mounting bracket 401 of the rearing pool 1, is activated. The output shaft of the cylinder 402 pushes the connecting bracket 4 upward, which in turn drives the top rod 209 on the top surface of the connecting bracket 4 upward. The top rod 209 passes through the drain pipe 206 at the bottom of the rearing chamber 202 and abuts against the sealing cover 207, lifting the sealing cover 207. At this time, the water and impurities in the rearing chamber 202 pass through the filter cover 208 and are discharged through the drain pipe 206. After the drainage is completed, the cylinder 402 retracts, the top rod 209 descends, and the sealing cover 207 resets under the action of gravity to achieve sealing. Then, new water is added to the rearing chamber 202 through the spray pipe 501 fixed between the support plates 5. Through the synergistic effect of this movable rearing chamber 202 and the external centralized drainage control mechanism, this utility model solves the problem of the fish fry rearing pool 1 being difficult to manage in sections, operate independently, and change water efficiently in the prior art.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
