Description

Technical Field

[0001] The utility model relates to the technical field of grass carp breeding, in particular to grass carp breeding net cage equipment. Background Art

[0002] In the field of aquaculture, grass carp farming has always been an important part of the industry, occupying a considerable market share. Grass carp is deeply loved by consumers for its delicious meat and high nutritional value, and the market demand continues to grow. Aquaculture operators have continuously improved the farming efficiency and quality of grass carp through scientific farming techniques and modern management methods to meet market demand. In addition, grass carp farming has also driven the development of related industrial chains, such as feed production, fish disease prevention and control, processing and sales, etc., and has made positive contributions to the development of the local economy.

[0003] Traditional aquaculture methods often face the problem of poor water flow control. Grass carp needs a suitable water flow environment to grow. The water flow can not only provide sufficient dissolved oxygen, but also simulate the natural water environment to promote the swimming of grass carp, enhance its physique and meat quality. However, ordinary aquaculture facilities have difficulty in controlling the direction and speed of water flow, which can easily cause water flow disorder or local water flow stagnation. Although simple cage farming has improved the mobility and some water quality conditions of aquaculture to a certain extent, it still has obvious shortcomings. Its water flow exchange mainly depends on natural water flow or limited aeration equipment. The water flow has poor fluidity and is difficult to control the direction. Poor water flow will lead to large differences in water quality in different areas of the cage, and problems such as insufficient local dissolved oxygen and uneven distribution of nutrients will frequently occur. Utility Model Content

The circulating water tank 1 is connected with the filter water tank through the installation opening, and a circulating submersible pump is fixedly installed inside the installation opening, and a fixing plate is fixedly installed on the outer wall of the circulating submersible pump.

[0008] A circulating submersible pump is set up. As the core power source of the water circulation and filtration part, the circulating submersible pump can effectively drive the water in the breeding tank to circulate between circulating water tank 1, circulating water tank 2, fish pond and filtration water tank. Through continuous operation, it ensures that the entire breeding water body is in a constant state of movement, avoiding the deterioration of water quality caused by local water stagnation, such as uneven dissolved oxygen distribution, accumulation of harmful substances, etc.

[0009] Preferably, the fixed plate is fixedly installed on the inner wall of the filtered water tank, and the output end and input end of the circulating submersible pump are respectively connected with a bend pipe 1 and a bend pipe 2, the other end of the bend pipe 1 is arranged inside the circulating water tank 1, and the other end of the bend pipe 2 is arranged inside the filtered water tank, and a filter box is arranged inside the filtered water tank.

[0011] A water pump is provided, which can actively pump out the water in the breeding tank and transport it to other components. For example, a circulating submersible pump pumps the water in the circulating water tank to the filter water tank for purification and then returns it, so that the water in the breeding tank can be continuously circulated.

[0012] Preferably, a water pumping branch pipe is provided at the bottom of the fixed sleeve, and the water pumping branch pipe is connected to the water pumping main pipe. A water pumping main pipe support block is fixedly installed on the top of the circulating water tank 2, and an installation groove is provided on the water pumping main pipe support block, and the installation groove is adapted to the water pumping main pipe. The other end of the water pumping branch pipe extends to the interior of the circulating water tank 2, and the output end of the water pump is provided with an output elbow pipe, and the other end of the output elbow pipe extends to the interior of the filtered water tank.

[0013] Preferably, the one-way guide part specifically includes: installation circular openings, equidistantly opened on the inner wall of the isolation wall; installation plates, fixedly installed on both sides of the inner wall of the isolation wall; diversion submersible pumps, equidistantly arranged inside the grass carp breeding box; and a fish pond, opened between the isolation wall and the inner wall of the grass carp breeding box.

[0014] Preferably, the installation circular opening is connected with the through opening, the fish pond is connected through the installation circular opening, and the fish pond is respectively connected with the circulating water tank one and the circulating water tank two through the through opening, the installation plate is fixedly sleeved on the outer wall of the diversion submersible pump, and the diversion submersible pump is respectively fixedly installed inside the installation circular opening and the through opening through the installation plate, the input end of the diversion submersible pump is connected with a diversion elbow, and the output end of the diversion submersible pump is connected with a diversion output pipe, the outer wall of the diversion output pipe is fixedly connected with connecting rods equidistantly around the circumference, the other end of the connecting rod is fixedly connected with a guide plate, and the guide plate is provided with slow flow holes equidistantly around the circumference.

[0015] A diversion submersible pump is set up, which plays a key role in guiding water flow in the entire aquaculture cage equipment. Through its reasonable layout and operation, it can accurately control the flow direction of water. The water drawn from the circulating water tank 1 is transported to various areas of the fish pond in an orderly manner under the action of the diversion submersible pump, ensuring that the water flows in the fish pond according to the preset path. In conjunction with the circulating water tank 1, circulating water tank 2 and the filter water tank, the diversion submersible pump effectively promotes the circulation and exchange of the entire aquaculture water body. After the water from the circulating water tank 1 is transported to the fish pond, the water flows in the fish pond and interacts with the grass carp. After absorbing impurities such as grass carp excrement, it flows into the circulating water tank 2. This circulation mode ensures the continuous renewal of the aquaculture water body and maintains the relative stability of the water quality.

[0016] The utility model provides a grass carp breeding cage device, which has the following beneficial effects:

[0017] (1) The utility model provides equidistantly fixed screen plates in the filter box of the water circulation filter part. These screen plates can filter out large particles of impurities in the aquaculture water. Through the filtering effect of the screen plates, the water body can be kept relatively clean, and the accumulation of harmful substances in the water can be reduced, thereby creating a healthy living environment for grass carp. In the process of grass carp aquaculture, if there is no effective water recycling mechanism, the aquaculture water needs to be replaced frequently, which will consume a large amount of water resources and increase the aquaculture cost.

[0018] (2) The utility model can make the water flow in the breeding box flow stably in a specific single direction through the coordinated effect of the one-way guide part, the guide submersible pump, the guide plate and other structures. For grass carp, the stable water flow environment simulates the water flow state in natural water bodies, which helps them maintain good physiological functions and movement habits. It provides water flowing in one direction, and the fish in the cage have a reverse flow time of nearly one month according to their habit of liking to flow against the current. In this way, the meat is firmer and the taste is better. BRIEF DESCRIPTION OF THE DRAWINGS

During the grass carp breeding process, if there is no effective water recycling mechanism, it is necessary to frequently replace the breeding water, which will consume a lot of water resources and increase the breeding cost.

[0034] Embodiment 2:

[0035] On the basis of the first embodiment, a preferred embodiment of a grass carp breeding cage device provided by the utility model is as follows: Figure 1-4 As shown: the one-way guide part 4 specifically includes: a mounting circular opening 411, which is equidistantly opened on the inner wall of the isolation wall 2; a mounting plate 413, which is fixedly installed on both sides of the inner wall of the isolation wall 2; a diversion submersible pump 414, which is equidistantly arranged inside the grass carp breeding box 1; and a fish pond 412, which is opened between the isolation wall 2 and the inner wall of the grass carp breeding box 1.

[0036] The installation circular opening 411 is connected with the through opening 313, the fish pond 412 is connected through the installation circular opening 411, the fish pond 412 is respectively connected with the circulating water tank 1 311 and the circulating water tank 2 312 through the through opening 313, the installation plate 413 is fixedly sleeved on the outer wall of the diversion submersible pump 414, the diversion submersible pump 414 is respectively fixedly installed inside the installation circular opening 411 and the through opening 313 through the installation plate 413, the input end of the diversion submersible pump 414 is connected with a diversion elbow 418, the output end of the diversion submersible pump 414 is connected with a diversion output pipe 415, the outer wall of the diversion output pipe is fixedly connected with connecting rods 416 at equal intervals on the circumference, the other end of the connecting rod 416 is fixedly connected with a guide plate 417, and the guide plate 417 is provided with slow flow holes at equal intervals on the circumference.

[0037] In the process of this embodiment, the diversion submersible pump 414 is started, and the diversion submersible pump 414 sucks water from the circulating water tank 311 through the diversion elbow 418. After the water is sucked in, it is discharged to the fish pond 412 through the diversion output pipe 415. The water discharged from the diversion output pipe 415 changes its flow direction under the action of the guide plate 417. Since the guide plate 417 is provided with slow flow holes at equal intervals on the circumference, the water will form a unidirectional flow in the fish pond 412 in a relatively uniform and stable state, and then the water in the fish pond 412 is transferred to the fish pond 412 by the diversion submersible pump 414. It is discharged into the interior of the circulating water tank 2 312 through the diversion output pipe 415, and circulates in the breeding box 1 according to the set direction, so that the water flow in the breeding box 1 can flow stably in a specific single direction. For grass carp, the stable water flow environment simulates the water flow state in natural water bodies, which helps them maintain good physiological functions and movement habits. It provides water flowing in one direction. The fish in the cage have a reverse flow time of nearly one month according to their own habit of liking countercurrent. This makes the meat firmer and taste better.

[0038] Working principle: When in use:

[0039] Step 1: Check the integrity of the grass carp breeding box 1, ensure that the isolation wall 2 is firmly installed on the inner wall of the breeding box 1 without damage or gaps to prevent the grass carp from escaping or abnormal water flow, and check whether the components of the water circulation and filtration part 3, including the circulating water tank 1 311, the circulating water tank 2 312 and the filtered water tank 3118, are installed correctly and well sealed. Check the fixing of the circulating submersible pump 315 at the mounting port 314, ensure that the fixing plate 316 is firmly connected to the circulating submersible pump 315 and the inner wall of the filtered water tank 3118, and that the elbow 1 317 and the elbow 2 3119 are tightly connected without leakage, check the filter box 318 inside the filtered water tank 3118, confirm that the screen plate 319 is firmly installed and not blocked, and the handle is easy to operate for subsequent cleaning and maintenance, check the one-way flow guide part 4, check whether the mounting circular port 411 is unobstructed, the mounting plate 413 is firmly fixed on both sides of the inner wall of the isolation wall 2, the diversion submersible pump 414 is stably installed in the mounting circular port 411 and the through port 313 through the mounting plate 413, the diversion elbow 418 and the diversion output pipe 415 are connected normally, the slow flow hole on the guide plate 417 is not blocked, and the connecting rod 416 is reliably connected;

[0040] Step 2: Start the circulating submersible pump 315. The circulating submersible pump 315 extracts the preliminarily filtered water from the filtered water tank 3118 through the elbow 2 3119, and then transports the water to the circulating water tank 1 311 through the elbow 1 317. At this time, the water accumulates in the circulating water tank 1 311 and flows into the fish pond 412 through the port 313 to guide the submersible pump 414, starting the preliminary process of circulating in the breeding tank 1. Start the water pump 3113. The water pump 3113 flows through the water pumping main 3114 and The water extraction branch pipe 3116 extracts water from the second circulating water tank 312. The water in the second circulating water tank 312 flows into the fish pond 412 through the port 313 and is then extracted by the water extraction pump 3113. The water extraction pump 3113 transports the water back to the filter water tank 3118 through the output elbow pipe 3112. The water entering the filter water tank 3118 is filtered through the screen plate 319 in the filter box 318 to remove impurities, grass carp excrement, leftover bait and other pollutants in the water, thereby realizing the circulation filtration and purification of the aquaculture water and maintaining the stable water quality.

[0041] Step 3: Start the diversion submersible pump 414, which draws water from the circulating water tank 1 311 through the diversion elbow 418. After the water is drawn in, it is discharged to the fish pond 412 through the diversion output pipe 415. The water discharged from the diversion output pipe 415 changes its flow direction under the action of the guide plate 417. Since the guide plate 417 is provided with slow-flow holes equidistantly around the circumference, the water will form a unidirectional flow in the fish pond 412 in a relatively uniform and stable state. Then, the water in the fish pond 412 is discharged into the circulating water tank 2 312 through the diversion output pipe 415 by the diversion submersible pump 414, and circulates in the culture box 1 in the set direction, thereby creating a suitable water flow environment for the grass carp, promoting the growth of the grass carp, and facilitating the uniform mixing and purification of the water quality in the culture box 1.

[0042] Step 4: Regularly check the operating status of the circulation submersible pump 315, the water pump 3113 and the diversion submersible pump 414, including indicators such as sound, vibration, and temperature, to ensure the normal operation of the water pump. If there is any abnormality, shut down the machine for inspection or replacement in time. Regularly check the screen plate 319 in the filter box 318. When it is found that the screen plate 319 is blocked and seriously affects the filtration efficiency, take out the filter box 318 through the handle for cleaning or replace the screen plate 319 to ensure the filtration effect of the water circulation filter part 3, observe whether the water flow direction and speed in the fish pond 412 meet the breeding requirements, if the water flow is abnormal, check whether the guide plate 417 is damaged, whether the working parameters of the diversion submersible pump 414 change, etc., adjust or repair related components in time to ensure the normal operation of the one-way diversion part 4 and maintain a stable water flow environment and good water quality in the breeding box 1.
