Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to an outdoor intelligent aquaculture system. Background Art

[0002] At present, many aquaculture-related scientific research institutions are still conducting breeding experiments indoors, but this is unrealistic for many breeding species. In order to make the breeding test data more scientific, most breeding species should be tested in outdoor places such as breeding ponds, high-level ponds or seawater breeding cages. However, these outdoor places are generally remote, and many scientific researchers cannot be stationed on the front line in real time, especially faculty and staff of colleges and universities, who often cannot understand the breeding situation in a timely or comprehensive manner. On the other hand, when conducting breeding experiments, artificial feeding may bring in some subjective factors. For example, some students may take more careful care of a certain experimental group to make it grow better if they want it to be good. The intelligent automatic breeding system can avoid these factors, and the video recorded during the breeding process can also be used as an important indicator for evaluating the breeding status. In addition, in the process of aquaculture, feeding fish is an important step. It is necessary to mix feeds of different formulas or feeds and medicines, and then use automatic feeders to feed them. This reduces the feeding efficiency, and once the feed is blocked in the automatic feeder, it affects the feeding effect. The automatic feeder has a small coverage area and uneven feeding, which will also affect the smooth feeding of fish, all of which will have an adverse effect on aquaculture. For this reason, we have launched an outdoor intelligent aquaculture system. Summary of the invention

[0056] The scraper mechanism 109 includes a top support ring 1091, a bottom support ring 1093, a truncated cone cylinder 1092 connected between the top support ring 1091 and the bottom support ring 1093, and scrapers 1094 arranged at equal intervals on the truncated cone cylinder 1092 and the bottom support ring 1093; an upper support protrusion ring 1104 is arranged on the outer wall of the inner ring seat 1103, and a lower support protrusion ring 1105 is arranged on the lower part of the inner wall of the outer ring seat 1101, the top support ring 1091 is located on the upper end of the upper support protrusion ring 1104, and the bottom support ring 1093 is located on the upper end of the lower support protrusion ring 1105.

[0057] The stirring mechanism 107 includes a stirring disc 1071 disposed inside the feed temporary storage tank 102 and stirring plates 1072 arranged at equal intervals on the upper end of the stirring disc 1071; the stirring disc 1071 is fixed on the top of the vertical shaft 1131, and the stirring disc 1071 is arranged in a shape that is narrow at the top and wide at the bottom.

[0058] The transmission mechanism 113 includes a motor shaft 1137 at the output end of the motor 115 extending into the transmission box 106 and then connected to a driving gear 1136, a bottom gear 1135 meshed with the lower end of the driving gear 1136, and a top gear 1138 meshed with the top of the driving gear 1136; the diameter of the bottom gear 1135 is smaller than the diameter of the driving gear 1136, so that when the motor 115 drives the driving gear 1136 to rotate, the bottom gear 1135 and the first rotating rod 1138 can be used to rotate the driving gear 1136. 134 drives the fan blades 114 to rotate at high speed so that the fan blades 114 form a negative pressure in the bell mouth 1053; the first rotating rod 1134 fixed at the middle part of the front end of the bottom gear 1135 penetrates the partition 1061 in the transmission box 106 and is connected to the middle part of the fan blade 114, and the second rotating rod 1139 fixed at the middle part of the front end of the top gear 1138 penetrates the partition 1061 and is connected to the worm 1133, and the worm 1133 is engaged with the worm wheel 1132 fixed on the vertical shaft 1131.

[0059] An air inlet groove 1052 is provided on the rear surface of the feeding cylinder 105, the bottom of the inclined tube 111 is connected to the opening 1051 at the front of the upper end of the feeding cylinder 105, and a bell mouth 1053 located in front of the fan blade 114 is provided inside the feeding cylinder 105, and the bell mouth 1053 is set in a shape of being narrow in front and wide in the back. The setting of such a bell mouth 1053 can increase the flow rate of the air blown out through the front end of the bell mouth 1053, thereby forming a negative pressure in the inclined tube 111, so that the feed in the receiving trough 1102 is sucked into the inclined tube 111, and after the feed enters the inside of the feeding cylinder 105, the air blown out from the front end of the bell mouth 1053 blows the feed out evenly, thereby improving the coverage of the feed feeding and feeding more evenly.

[0060] Specifically, when in use, two different sensors 8 are integrated on each row of fish fillets 7, and the sensor 8 is a thermometer, a salinometer, a turbidity meter, a water level sensor, a pH meter or a dissolved oxygen meter; the thermometer is used to detect water temperature data, the salinometer is used to detect water reading data, the turbidity meter is used to detect turbidity data of the water body, the water level sensor is used to detect water level data of the water body, the pH meter is used to detect pH data of the water body, and the dissolved oxygen meter is used to detect dissolved oxygen content data of the water body.

[0061] The experimental cage 9 is equipped with two sets of cameras, one on the water surface and the other on the bottom of the water, for real-time monitoring of fish behavior. This reduces human intervention, making the aquaculture test data more accurate and reliable, while freeing up student labor and allowing students to devote more time to literature reading and data mining.

[0062] The motor 115 works, so that the motor 115 drives the driving gear 1136 to rotate through the motor shaft 1137, and the driving gear 1136 drives the second rotating rod 1139 and the worm 1133 to rotate through the top gear 1138, and the worm 1133 drives the vertical shaft 1131 and the stirring plate 1071 connected to the top of the vertical shaft 1131 to rotate through the worm gear 1132;

[0063] The stirring disc 1071 rotates inside the feed temporary storage trough 102, so that the stirring plate 1072 on the stirring disc 1071 stirs and mixes the feed inside the feed temporary storage trough 102. At the same time, by stirring and mixing the feed inside the feed temporary storage trough 102, the feed can be prevented from being blocked at the bottom of the feed temporary storage trough 102, so that the feed falls into the V-shaped groove 1081 of the annular material guide seat 108 through the gap between the feed temporary storage trough 102 and the stirring disc 1071 under the action of its own gravity; because a plurality of groups of equally spaced leakage ports 1082 are provided at the bottom of the V-shaped groove 1081, the feed in the V-shaped groove 1081 can fall into the receiving trough 1102 through the leakage ports 1082.

[0064] At this time, since the vertical shaft 1131 drives the cone cylinder 1092 through the connecting arm 112, the scraper mechanism 109 rotates as a whole in the receiving trough 1102, so that the scraper 1094 can stir the feed in the receiving trough 1102 again, and prevent the feed from accumulating in the receiving trough 1102; since the driving gear 1136 drives the fan blade 114 to rotate at a high speed through the bottom gear 1135 and the first rotating rod 1134, the fan blade 114 forms a negative pressure in the bell mouth 1053, and the outside air passes through the air intake opening The groove 104 and the air inlet groove 1052 enter into the bell mouth 1053, so that the air is blown out through the front end of the bell mouth 1053 at a faster speed, and a negative pressure is formed in the inclined tube 111. As the scraper 1094 stirs the feed in the receiving trough 1102, the negative pressure formed in the inclined tube 111 sucks the feed in the receiving trough 1102 into the inclined tube 111, and after the feed enters the inside of the feeding tube 105, the air blown out from the front end of the bell mouth 1053 blows the feed out evenly, thereby increasing the coverage of feed feeding and making the feeding more even.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
