Abstract
Description
Technical Field
[0001] This utility model relates to the field of fish fry breeding technology, and in particular to a fish fry breeding basin. Background Technology
[0002] Fish fry rearing is a crucial step in aquaculture, directly impacting the yield and profitability of subsequent adult fish farming. In small-scale farming, farmers use smaller tools such as rearing basins to facilitate water changes, feeding, and other operations.
[0003] In existing technology, when changing the water in fish fry rearing basins, the water is usually poured out and fresh water is added. During this process, smaller fish fry are likely to be washed out with the dirty water, affecting their survival rate. Furthermore, overturning the basins causes significant disturbance to the fry, which is detrimental to their growth. Therefore, an improved fish fry rearing basin is proposed. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to provide a fish fry breeding basin to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, one embodiment of the present invention provides a fish fry rearing basin, including a basin body, a drain pipe at the bottom of the basin body, a filter screen inside the basin body outside the drain pipe, and a control pipe with a length greater than the height of the basin body inside the filter screen, which can cover the upper end of the drain pipe to prevent water from flowing in.
[0007] Preferably, in any of the above embodiments, the bottom surface of the basin adopts an inclined structure that converges towards the center, and the drain pipe is located in the middle of the basin.
[0008] The above technical solution employs the following: The basin provides a rearing space for the fish fry, and its volume should be sufficient to meet the growth needs of the fish fry. A drain pipe is used to discharge wastewater from the basin. It is positioned in the center of the basin for easy drainage of wastewater from all parts of the basin. The bottom of the basin has a sloping structure to facilitate the flow of feces and uneaten feed from the wastewater to the drain pipe.
[0009] Preferably, in any of the above solutions, the filter screen is fixedly connected to the bottom of the basin by means of waterproof adhesive.
[0010] The above technical solution involves installing a filter screen inside the basin to block the fish fry and prevent them from being discharged with wastewater through the drain pipe. It should be noted that the mesh size of the filter screen should be controlled according to the size of the fish fry, ensuring that the fry cannot pass through. The filter screen is fixed by adhesive, making it readily available and easy to install.
[0011] Preferably, the bottom of the basin is provided with a support block whose bottom surface is lower than the bottom of the drain pipe.
[0012] The above technical solution involves placing the basin above the drainage trough during normal use, ensuring the drain pipe is inside the trough. This allows wastewater to drain directly into the trough. Support blocks are installed at the bottom of the basin to provide height support. There's no need to restrict the basin's placement above the drainage trough, as long as wastewater can be discharged normally, facilitating drainage through the drain pipe.
[0013] Preferably, in any of the above embodiments, the regulating pipe is sleeved on the outside of the drain pipe, and a handle is fixedly connected to the top end of the regulating pipe.
[0014] The above technical solution employs a control pipe to regulate the opening and closing of the upper end of the drain pipe. The control pipe is fitted onto the outside of the drain pipe, blocking the water flow from the outside. Simultaneously, the drain pipe also constrains the control pipe, preventing it from tilting. A handle is installed at the top of the control pipe for easy access by aquaculture personnel.
[0015] Preferably, the bottom end of the control tube has a tapered structure, and when it is fitted onto the drain pipe, the narrowest part of the tapered section is tightly fitted to the outer wall of the drain pipe.
[0016] The above technical solution adopts a tapered structure at the bottom of the control pipe to facilitate its connection to the drainage pipe.
[0017] Preferably, in any of the above embodiments, the control tube is inserted into the drain pipe and its outer wall is tightly fitted to the inner wall of the drain pipe.
[0018] The above technical solution involves inserting a control pipe into the drain pipe to block the water flow from the inside, preventing water from flowing out of the breeding basin when drainage is not required.
[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0020] 1. This fish fry rearing basin, with its structure including a basin body, drain pipe, filter screen, and regulating pipe, is designed for normal use. The basin is placed above the drain trough, with the drain pipe positioned within it. The regulating pipe is installed and ensured to seal the upper end of the drain pipe. When a water change is needed, the regulating pipe is removed, allowing water in the basin to flow into and out of the drain pipe. Simultaneously, the filter screen prevents the fish fry from escaping. Afterward, fresh water is added to the basin, the regulating pipe is reinstalled, and the drain pipe is sealed, completing the water change process. The fish fry are not lost, and the disturbance caused by water changes is minimal, making it highly practical.
[0021] 2. This fish fry rearing basin has a drain pipe positioned in the center of the basin for easy drainage of wastewater from all parts of the basin. The bottom of the basin has a sloping structure to facilitate the flow of feces and uneaten feed in the wastewater towards the drain pipe. Support blocks are installed at the bottom of the basin to provide support and maintain its height. There is no need to restrict the rearing basin to be placed above the drainage trough, as long as the wastewater can be discharged normally, facilitating drainage through the drain pipe.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0031] like Figures 1-4 As shown, this utility model includes a basin 1, a drain pipe 2 at the bottom of the basin 1, a filter screen 3 inside the basin 1 outside the drain pipe 2, and a regulating pipe 4 inside the filter screen 3 with a length greater than the height of the basin 1, which can cover the upper end of the drain pipe 2 to prevent water from flowing in.
[0032] Example 1: The bottom of the basin 1 has an inclined structure that converges towards the center, and the drain pipe 2 is located in the middle of the basin 1. The basin 1 provides a breeding space for fish fry and should have a certain volume to meet the growth needs of the fish fry to be raised. The drain pipe 2 is used to drain the sewage in the basin 1. Its location in the middle of the basin 1 facilitates the discharge of sewage from various parts of the basin 1. The inclined structure of the bottom of the basin 1 facilitates the flow of feces and uneaten feed in the sewage to the drain pipe 2. The filter screen 3 is fixedly connected to the bottom of the basin 1 by waterproof adhesive. The filter screen 3 is installed inside the basin 1 to block the fish fry and prevent them from being discharged with the sewage through the drain pipe 2. It should be noted that the pore size of the filter screen 3 should be controlled according to the size of the fish fry, ensuring that the fish fry cannot pass through. The filter screen 3 is fixed by adhesive, which is readily available and easy to install.
[0033] Example 2: The bottom of the basin 1 is equipped with a support block whose bottom surface is lower than the bottom of the drain pipe 2. During normal use, the basin 1 should be placed above the drainage trough, so that the drain pipe 2 is inside the drainage trough, allowing wastewater discharged from the drain pipe 2 to directly flow into the drainage trough and be discharged away. The support block at the bottom of the basin 1 provides support and a certain height, eliminating the need to restrict the basin's placement above the drainage trough, as long as wastewater can be discharged normally, facilitating drainage through the drain pipe 2.
[0034] The regulating pipe 4 is fitted onto the outside of the drain pipe 2, and a handle is fixedly connected to the top of the regulating pipe 4. The regulating pipe 4 is used to regulate the opening and closing of the upper end of the drain pipe 2. The regulating pipe 4, fitted onto the outside of the drain pipe 2, blocks the water flow from the outside, while the drain pipe 2 also constrains the regulating pipe 4 to prevent it from tilting. A handle is provided at the top of the regulating pipe 4 for easy access by aquaculture personnel. The bottom end of the regulating pipe 4 has a tapered structure, and when fitted onto the drain pipe 2, the narrowest part of the tapered section fits tightly against the outer wall of the drain pipe 2. The tapered structure at the bottom end of the regulating pipe 4 facilitates its fitting onto the drain pipe 2.
[0035] Example 3: The regulating pipe 4 is inserted into the drain pipe 2, and its outer wall is tightly fitted to the inner wall of the drain pipe 2. The regulating pipe 4 is inserted into the drain pipe 2 to block the water flow from the inside, preventing water from flowing out of the breeding basin when drainage is not required.
[0036] The working principle of this utility model is as follows:
[0037] S1. Place basin 1 above the drainage trough, so that drain pipe 2 is inside the drainage trough. Install the regulating pipe 4 and ensure that it blocks the upper end of drain pipe 2;
[0038] S2. When a water change is needed, remove the control pipe 4. The water in the basin 1 will begin to flow into the drain pipe 2 and be discharged through the drain pipe 2. At the same time, the filter screen 3 will block the fish fry and prevent them from flowing away.
[0039] S3. Pour new water into basin 1, reinstall the control pipe 4, and seal the drain pipe 2 to complete the water change.
[0040] Compared with the prior art, the present invention has the following advantages:
[0041] 1. This fish fry rearing basin, consisting of a basin body 1, a drain pipe 2, a filter screen 3, and a regulating pipe 4, is designed for normal use. The basin body 1 is placed above the drain trough, with the drain pipe 2 positioned within it. The regulating pipe 4 is installed and ensured to seal the upper end of the drain pipe 2. When a water change is needed, the regulating pipe 4 is removed, allowing water in the basin body 1 to flow into and out of the drain pipe 2. Simultaneously, the filter screen 3 prevents the fish fry from escaping. New water is then added to the basin body 1, the regulating pipe 4 is reinstalled, and the drain pipe 2 is sealed, completing the water change. The fish fry are not lost, and the disturbance caused by water changes is minimal, making it highly practical.
[0042] 2. In this fish fry rearing basin, the drain pipe 2 is located in the middle of the basin body 1 to facilitate the discharge of wastewater from various parts of the basin body 1. The bottom of the basin body 1 has a sloping structure to facilitate the flow of feces and uneaten feed in the wastewater to the drain pipe 2. A support block is installed at the bottom of the basin body 1 to support it and give it a certain height. There is no need to restrict the rearing basin to be placed above the drainage trough, as long as the wastewater can be discharged normally, it is convenient for the drain pipe 2 to drain water.
