Description

Technical Field

[0001] This utility model relates to the field of grass carp fry farming, and in particular to an automatic waste removal and excrement collection device for grass carp fry. Background Technology

[0002] Grass carp is one of the important freshwater aquaculture fish in my country. During the fry rearing stage, it is necessary to provide a good growth environment for the fry to improve their survival rate and growth rate. With the continuous expansion of the aquaculture scale and the increasing prevalence of intensive aquaculture methods, the amount of pollutants in the aquaculture water has increased significantly, so it is necessary to clean up the feces.

[0003] Currently, cleaning grass carp fry typically relies on manual labor to periodically remove feces, uneaten feed, and other pollutants from the rearing ponds. This method is not only labor-intensive but also inefficient, making it difficult to meet the needs of large-scale aquaculture. Furthermore, the frequency of manual cleaning is often limited, failing to remove pollutants in a timely manner, leading to water quality deterioration and affecting the growth and health of grass carp fry. To address these issues, we propose an automatic cleaning and waste collection device for grass carp fry. Utility Model Content

[0004] The purpose of this invention is to provide an automatic waste removal and excrement collection device for grass carp fry to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic waste collection and cleaning device for grass carp fry includes a fry rearing frame, a support base fixedly installed on one side of the fry rearing frame, a waste collection component fixedly installed on the upper surface of the support base, a support base fixedly installed on the bottom surface of the fry rearing frame, a circulating water pump fixedly installed on the upper surface of the support base, a delivery pipe fixedly connected to the output end of the circulating water pump, a connector movably connected to one end of the delivery pipe, a connecting pipe movably connected to one end of the connector, two ammonia nitrogen sensors fixedly installed on the inner bottom wall of the fry rearing frame, and a controller fixedly installed on the outer surface of the fry rearing frame.

[0007] In a further embodiment, the fecal collection assembly includes a fecal collection outer cylinder fixedly mounted on the upper surface of the support base, an annular threaded seat fixedly mounted on the outer surface of the fecal collection outer cylinder, and a fine filter cover provided inside the fecal collection outer cylinder, with a coarse filter plate threadedly connected to the inner wall of the fine filter cover.

[0008] In a further embodiment, the inner ring of the annular threaded seat is threadedly connected to a threaded sealing cap, and a sealing ring is provided on the inner bottom wall of the annular threaded seat. The bottom end of the threaded sealing cap is in close contact with the upper surface of the sealing ring, and the bottom end of the connecting pipe passes through the threaded sealing cap and extends into the interior of the threaded sealing cap.

[0009] In a further embodiment, the input end of the circulating water pump is fixedly connected to an extraction pipe. One end of the extraction pipe passes through the fish fry rearing frame and extends into the interior of the fish fry rearing frame. The interior of the fish fry rearing frame is provided with a drain pipe. One end of the drain pipe passes through the support base and the feces collection outer cylinder in sequence and extends into the interior of the feces collection outer cylinder.

[0010] In a further embodiment, a transparent observation plate is fixedly embedded on the outer surface of the fish fry rearing frame, and two support plates are fixedly installed on the outer surface of the fish fry rearing frame.

[0011] In a further embodiment, the ammonia nitrogen sensor is electrically connected to the controller via a wire, and the controller is electrically connected to the circulating water pump via a wire.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes an ammonia nitrogen sensor installed inside the fish fry rearing frame to monitor water quality in real time. In conjunction with a controller, if the ammonia nitrogen level exceeds the standard, the controller automatically activates a circulating water pump. This pump, along with the delivery pipe, connector, and connecting pipe, extracts and discharges pollutants such as feces and uneaten feed deposited at the bottom of the rearing frame into a waste collection assembly. This achieves continuous automated monitoring and cleaning, improving cleaning efficiency and effectively removing harmful substances like ammonia nitrogen produced from the decomposition of feces and uneaten feed, thus providing an excellent growth environment for the fish fry.

[0022] Please see Figures 1-4This utility model discloses an automatic waste collection and cleaning device for grass carp fry, comprising a fry rearing frame 1, a support base 2 fixedly installed on one side of the fry rearing frame 1, a waste collection component 3 fixedly installed on the upper surface of the support base 2, a support base 7 fixedly installed on the bottom surface of the fry rearing frame 1, a circulating water pump 8 fixedly installed on the upper surface of the support base 7, a delivery pipe 4 fixedly connected to the output end of the circulating water pump 8, a connector 5 movably connected to one end of the delivery pipe 4, a connecting pipe 6 movably connected to one end of the connector 5, two ammonia nitrogen sensors 10 fixedly installed on the inner bottom wall of the fry rearing frame 1, and a controller 14 fixedly installed on the outer surface of the fry rearing frame 1. The fish fry rearing frame 1 is used to accommodate grass carp fry and the aquaculture water, providing a living space for the fry. The support base 2 provides stable support for the waste collection component 3, ensuring stable operation of the waste collection component 3. The ammonia nitrogen sensor 10 can monitor the ammonia nitrogen content in the water in real time, providing data support for water quality changes. The controller 14 receives the data from the ammonia nitrogen sensor 10 and controls the start and stop of the circulating water pump 8 according to the preset threshold, realizing intelligent control of the entire cleaning process. In addition, the electrical components in this utility model are all common electrical devices in the prior art, and this application will not elaborate on their models or internal structures.

[0023] In a further embodiment, the waste collection assembly 3 includes a waste collection outer cylinder 301 fixedly mounted on the upper surface of the support base 2. An annular threaded seat 304 is fixedly mounted on the outer surface of the waste collection outer cylinder 301. A fine filter cover 302 is provided inside the waste collection outer cylinder 301. A coarse filter plate 303 is threadedly connected to the inner wall of the fine filter cover 302. A threaded sealing cap 306 is threadedly connected to the inner ring of the annular threaded seat 304. A sealing ring 305 is provided on the inner bottom wall of the annular threaded seat 304. The bottom end of the threaded sealing cap 306 is in close contact with the upper surface of the sealing ring 305. The bottom end of the connecting pipe 6 passes through the threaded sealing cap 306 and extends to... Inside the threaded sealing cover 306, a coarse filter plate 303 and a fine filter cover 302 are installed inside the outer sewage collection cylinder 301. After sewage enters the outer sewage collection cylinder 301, it first passes through the coarse filter plate 303 to intercept large particulate pollutants, and then passes through the fine filter cover 302 to further filter small particulate impurities, thus achieving dual filtration of sewage. In addition, the annular threaded seat 304 is fixed on the outer surface of the outer sewage collection cylinder 301 and can be threadedly connected to the threaded sealing cover 306 for easy disassembly and assembly. The sealing ring 305 can ensure the sealing between the threaded sealing cover 306 and the annular threaded seat 304 to prevent sewage leakage.

[0024] In a further embodiment, the input end of the circulating water pump 8 is fixedly connected to an extraction pipe 9. One end of the extraction pipe 9 passes through the fish fry rearing frame 1 and extends into the interior of the fish fry rearing frame 1. The interior of the fish fry rearing frame 1 is provided with a drain pipe 11. One end of the drain pipe 11 passes through the support base 2 and the waste collection outer cylinder 301 in sequence and extends into the interior of the waste collection outer cylinder 301. A transparent observation plate 12 is fixedly embedded on the outer surface of the fish fry rearing frame 1. Two support plates 13 are fixedly installed on the outer surface of the fish fry rearing frame 1. The ammonia nitrogen sensor 10 is electrically connected to the controller 14 via a wire. The device 14 is electrically connected to the circulating water pump 8 via a wire. With the extraction pipe 9, when the circulating water pump 8 is started, it can extract the sewage containing pollutants from the bottom of the fish fry rearing frame 1 and transport it to the waste collection assembly 3 for treatment through components such as the conveying pipe 4. With the drainage pipe 11, the clean water filtered by the coarse filter plate 303 and the fine filter cover 302 can flow back into the fish fry rearing frame 1, realizing the recycling of the aquaculture water. With the transparent observation plate 12, it is convenient for staff to observe the growth status of the fish fry and the clarity of the water in real time.

[0025] The working principle of this utility model is as follows: First, the fish fry breeding frame 1 contains the breeding water and fish fry. Then, the ammonia nitrogen sensor 10 monitors the ammonia nitrogen content in the water in the fish fry breeding frame 1 and transmits the data to the controller 14. When the ammonia nitrogen sensor 10 detects that the ammonia nitrogen content in the water exceeds the set threshold, it means that the harmful substances produced by the decomposition of pollutants such as feces and uneaten feed in the water have increased. At this time, the controller 14 controls the circulating water pump 8 to start working.

[0026] The circulating water pump 8 draws aquaculture water containing pollutants such as feces and uneaten feed from the bottom of the fish fry rearing frame 1 through the extraction pipe 9. The extracted wastewater enters the waste collection assembly 3 through the delivery pipe 4, connector 5, and connecting pipe 6. The wastewater first passes through the coarse filter plate 303 to intercept larger particles of pollutants, and the fine filter cover 302 further filters out smaller particles of impurities. After double filtration, the relatively clean water flows back into the fish fry rearing frame 1 through the drain pipe 11, realizing the recycling of aquaculture water and ensuring water quality stability. The pollutants such as feces and uneaten feed intercepted by the fine filter cover 302 and the coarse filter plate 303 remain in the waste collection outer cylinder 301. When it is necessary to clean the pollutants, the threaded sealing cap 306 can be unscrewed to easily clean the pollutants in the waste collection outer cylinder 301.
