Description

Technical Field

[0001] The present invention relates to the technical field of seawater aquaculture, and in particular to a seawater circulation aquaculture system with a pool bottom cleaning structure. Background Art

[0002] Land-based factory-scale seawater recirculating aquaculture is a new type of marine aquaculture. With the application of intelligent technologies to marine aquaculture, new aquaculture ponds are now equipped with intelligent temperature control, automatic feed delivery, real-time water quality monitoring, and automatic water exchange. This makes land-based factory-scale seawater recirculating aquaculture boast high stocking density, large feed delivery amounts, high yields, and immunity to external environmental interference. Despite these advantages, the high stocking density in the ponds makes precise control of feed delivery difficult. To promote the growth of aquacultured organisms, excessive feed is often applied. This causes the sedimentation and attachment of waste and excess feed, creating an environment ideal for the growth of pathogens and making them susceptible to contamination and disease. While current intelligent technologies can monitor water quality, if it exceeds standards, 40% of the total water volume in the pond can be replaced to regulate water quality. The disadvantage is that this adjustment only replaces part of the water in the breeding pond, which reduces the harmful substances in the breeding pond, but more pollutants settle and adhere to the bottom of the pond, and the pathogens still have a good growth environment. In the existing technology, if the pond bottom is to be cleaned, the farmed organisms must be transferred and the water in the breeding pond must be completely discharged before cleaning. Transferring the farmed organisms will cause obvious losses. Usually, this measure is only taken when there is an outbreak of disease in the breeding pond. Summary of the Invention

DETAILED DESCRIPTION

[0025] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined application purpose, the specific embodiments, structures, features and effects according to the present application are described in detail as follows in combination with the drawings and preferred embodiments.

[0026] Referring to Figures 1 to 6 , a seawater circulating culture system with a pool bottom cleaning structure, comprising a culture pond 1, an adjusting pool 2 and a treatment pool, a guide rail 8 with aeration function is fixed on the pool bottom 101, the guide rail can be made of stainless steel, the aeration pipe can still be made of PVC pipe or also made of stainless steel pipe, referring to Figure 1 and Figure 5As shown, the guide rail 8 includes straight sections 801 provided with air channels 804 and arc sections 802 connecting two straight sections 801, the arc sections 802 are connected to the upper part of the straight sections 801, the air channels 804 are connected to the aeration pipes 10, the straight sections 801 are provided with hole channels 803 in communication with the air channels 804 for aeration, and the arc sections 802 connect adjacent two straight sections 801. In the embodiment, the air channels 804 are arranged at the lower part of the straight sections 801 of the guide rail 8, so that the pulley 905 does not contact the aeration pipes 10 outside the guide rail 8, avoiding that the aeration pipes 10 hinder the movement of the pool bottom cleaning device 9 when the pool bottom cleaning device 9 turns along the arc sections 802. The pool bottom cleaning device 9 can move along the guide rail 8, and the pool bottom cleaning device 9 includes a cleaning assembly and a walking assembly, the cleaning assembly includes a sweeping disc 901 and a water suction port 903, the outer side of the sweeping disc 901 further includes a housing 902, the housing 902 is provided with the water suction port 903, and the housing 902 surrounds the outer side of the sweeping disc 901 for reducing the overflow of the sewage during cleaning and improving the working efficiency of the water suction port 903. In the embodiment, the cleaning time of the breeding pool is about 0.5 h, and the flow rate of the water suction port during each cleaning is 5 t-10 t / h. The walking assembly includes a propeller 904 arranged above a sealed waterproof box 906 and a pulley 905, the propeller 904 provides the power for movement, and the pulley 905 serves as a position limiter for the pool bottom cleaning device 9 moving along the guide rail 8. In the embodiment, the cross section of the guide rail 8 is T-shaped, the pulley 905 includes a side pulley matched with the side surface of the guide rail 8 and a lower pulley matched with the lower surface of the guide rail 8, the distance between the bottom surface of the sweeping disc 901 and the surface of the lower pulley 905 is slightly greater than the distance from the lower surface of the guide rail 8 to the pool bottom 101, so that the sweeping disc 901 is in close contact with the pool bottom 101, and in the rotating and cleaning process, the sweeping disc 901 will not be separated from the pool bottom 101 due to the complex effects of the water buoyancy and gravity, thereby affecting the cleaning effect. The pool bottom cleaning device 9 further includes a hose connected to the water suction port 903 and a pump, the other end of the hose is arranged in the adjusting pool 2, and the pool bottom cleaning device 9 can be further connected with a cable, the cable is connected to the outside for control or power supply, the adjusting pool 2 is communicated with the breeding pool 1 and the treatment pool, the water level of the adjusting pool 2 is the same as that of the breeding pool 1, and the adjusting pool 2 can directly drain water to the treatment pool.Preferably, grooves 3 are provided on the four corners and / or side walls of the breeding pond 1, and a moving rod 4 is provided in the groove 3. The upper end of the moving rod 4 and the rack 5 are fixed or integrally formed. The rack 5 cooperates with the gear, and the gear can drive the rack 5 and the moving rod 4 to move upward under the drive of the motor 908. A connecting interface 7 suitable for connecting the isolation net 6 is provided on the moving rod 4. The isolation net 6 is fixed on the moving rod 4 through the connecting interface 7. The initial position of the isolation net 6 is set at the bottom of the pond 101; a guide rail 8 is provided below the isolation net 6. The working principle is as follows: when the water quality deteriorates or the bottom of the pond 101 needs to be cleaned regularly, the moving rod 4 is controlled to rise so that the isolation net 6 rises slowly. After the isolation net 6 rises, the organisms in the breeding pond 1 follow to the space above. The isolation net 6 stops after rising to a predetermined height. The upper part is the breeding area and the lower part forms a cleaning space. The pool bottom cleaning device 9 enters the cleaning space, moves along the guide rail 8, and opens the sweeping disc 901 to clean and the water suction port 903 to suck away pollutants and sewage from the bottom of the pond 101. Although the rising isolation net 6 may increase the density of organisms in the culture pond 1, the impact is limited, as the duration is short and the water depth of the culture pond is typically several meters, while the height of the cleaning space is typically no more than half a meter. Once the pool bottom 101 is cleaned, the movable rod 4 moves downward, and the isolation net 6 returns to its original position. In this embodiment, since the isolation net 6 remains on the pool bottom 101 for a long time, it may also absorb pollutants and even overweight the filter, making it difficult to lift. Therefore, the pool bottom cleaning device 9 may also include a sweeping disc facing the isolation net 6, so that the sweeping disc 901 can clean the isolation net 6 to prevent pollutants absorbed on the filter from contaminating the culture pond and causing overweight.

[0027] In the above embodiment, referring to Figure 2 As shown, the isolation net 6 includes a water inlet 601 and an isolation portion connected to the water inlet 601. The pool bottom cleaning device 9 can enter the pool bottom 101 through the water inlet 601. The isolation portion is a columnar grid 602 fixed to the entrance. The grid 602 has a channel 603 defined therein. A guide rail 8 extends outward from the channel 603 of the grid 602 to the ground, where a docking station for the pool bottom cleaning device 9 is provided. When cleaning is required, the user simply follows the guide rail 8 from the water inlet 601 into the cleaning space of the pool bottom 101.

[0028] In the above embodiment, referring to Figure 5 As shown, the cleaning assembly includes a sweeping disc 901, a gear set 907, and a motor 908. The motor 908 and gear set 907 are housed in a sealed, waterproof box 906. The gear set 907 includes a bevel gear that converts the output direction of the motor shaft and a gear driven by the bevel gear. The gear is fixed to the sweeping disc shaft. The sweeping disc 901 is driven by the motor 908 to rotate and clean the pool bottom 101.

[0029] In the above embodiment, referring to Figure 1As shown, the diameter of the sweeping disc 901 is half of the distance between the adjacent aeration pipes. The pool bottom cleaning device 9 can clean most of the pool bottom 101 in a single operation.
