Description

A liquid live feed automatic feeding device for jellyfish cultivation

technical field

The invention relates to the technical field of marine organism cultivation equipment, and further relates to an automatic feeding device for liquid live feed for jellyfish cultivation.

Background technique

On the one hand, jellyfish is an important zooplankton, and the study of the living habits and distribution of jellyfish has important scientific significance for the study of the overall ecological environment of the ocean. On the other hand, the shape of jellyfish is very beautiful. With the increase of science popularization in recent years, jellyfish has been known, loved and praised by more and more people, and the demand for breeding of ornamental jellyfish has increased rapidly.

When breeding jellyfish in the laboratory or at home, the feed used is mostly liquid live feed, such as brine shrimp hatched in sea water. In terms of feeding, artificial direct feeding is still the main method at present. This method has the following shortcomings : 1) The feeding time is unscientific and irregular, which is far from the situation of continuous feeding of jellyfish in the natural environment, especially at night, when there is no one feeding for a long time, it is very unfavorable for the growth of jellyfish; 2) The amount of feeding is inappropriate, Inconsistency, it is very likely that there will be too much feeding, the feed will sink to the bottom and affect the water quality, and waste resources, or the feeding amount will be too small to meet the feeding needs of jellyfish, which will seriously affect the growth of jellyfish. 3) artificial feeding has a large workload and low efficiency, so the threshold for family breeding jellyfish is raised, which is not conducive to the popularization of ornamental jellyfish cultivation.

For a long time, people have been pursuing an automatic feeding device that can scientifically feed jellyfish. Most of the current automatic feeding devices try to discharge liquid at regular intervals to achieve quantitative purposes. However, the flow rate of liquid will vary with the height of the liquid level, Real-time changes due to changes in many factors such as liquid density cannot achieve precise feeding, and most of the existing devices are complex in structure, large in size, difficult to operate, and difficult to popularize. More importantly, the existing automatic feeding devices are only developed for liquid feed, but ignore the requirement of maintaining a high activity of live feed during jellyfish cultivation. Shortcomings such as oxygen supply make the existing automatic feeding device unable to meet the requirements of jellyfish cultivation.

Therefore, there is an urgent need for a reasonable structural design, a kind of automatic feeding device that can maintain the activity of live feed, and can realize qualitative, regular, quantitative, and fixed-point scientific feeding.

Contents of the invention

In view of this, the present invention provides an automatic feeding device capable of maintaining the activity of live feed and realizing qualitative, timing, quantitative and fixed-point scientific feeding.

The upper part of the side wall of the middle section of the discharge pipe is provided with a feed port, and the lower part is provided with a discharge port; the feeding assembly is slidably connected Alternately open or close the feed port and the discharge port in the discharge pipe to realize the feed cavity in the upper section of the discharge pipe or the discharge cavity in the lower section of the discharge pipe alternately with the storage bin communication; the controller controls the feeding assembly to slide along the inner cavity wall of the middle section of the discharge tube.

In the present invention, the feeding component is electrically connected with the controller, and the feeding component is controlled by timing, quantification, and fixed-point delivery through the controller, so that the feeding time can be scientific and regular, which is similar to or the same as the continuous feeding of jellyfish in the natural environment , which is conducive to the growth of jellyfish; the amount of feeding is consistent, eliminating the situation of affecting water quality and wasting resources, and meeting the feeding needs of jellyfish; high degree of automation and high efficiency, which is conducive to the popularization of ornamental jellyfish cultivation.

Further, the discharge pipe is cylindrical, and the feeding assembly includes an upper conductor coil, a strong magnetic piston and a lower conductor coil; the upper conductor coil is sleeved on the outer side of the upper part of the discharge pipe, and the lower conductor The snare is arranged on the outer side of the lower part of the discharge pipe, and the upper and lower conducting coils are electrically connected to the controller; the strong magnetic piston controls the current of the upper conducting coil and the lower conducting coil through the controller Leading to and controlling the slide of the strong magnetic piston in the middle of the discharge tube to alternately open or close the feed port and the discharge port.

Further, the outer diameter of the middle part of the discharge pipe is larger than the outer diameters of the upper part and the lower part.

Further, the strong magnetic piston consists of a cylindrical powerful magnet and two rubber pads, the upper part of the cylindrical powerful magnet is an N pole, and the lower part is an S pole, and the two rubber pads are respectively adhered to the cylindrical powerful magnet. The upper and lower parts of the peripheral side, the rubber pad is slidingly connected with the inner wall of the middle section of the discharge pipe.

Further, the storage silo includes a transparent circular tube with a scale on the cylinder wall, and a rubber piston is provided on the opposite side of the storage silo to the feed port and the discharge port, and the rubber piston is connected to the The cylinder wall of the above-mentioned storage bin is connected in a flexible and sealed manner.

Further, it also includes an LED lamp, the LED lamp is fixed on one side of the discharge nozzle, and the LED lamp is electrically connected to the controller.

Further, an air pump is also included, the air pump is electrically connected to the controller, the feed box is funnel-shaped, and the air pump is connected and communicated with the lower inclined surface of the feed box through an air duct.

Further, it also includes a water immersion sensor, the water immersion sensor is fixed on the outside of the lower slope of the feed box, the induction head of the water immersion sensor extends into the feed box through the wall of the feed box, and the water immersion sensor And it is electrically connected with the controller.

The working principle of the present invention is as follows: the controller is connected with the upper conductor coil, the lower conductor coil, the LED lighting lamp, the water immersion sensor and the air pump through the wire, and controls them. After the device is turned on, the air pump continues to work, continuously blowing air into the feed box through the air duct, providing oxygen for the bait organisms in the feed box, and maintaining the high activity of the bait organisms. The magnetic poles of the powerful magnet are fixed, the upper part is the N pole, and the lower part is the S pole. When the upper conducting coil passes through the current in the clockwise direction (from top to bottom), the lower conducting coil passes through the current in the counterclockwise direction (from top to bottom). When the current is flowing, the upper and lower conducting coils will generate magnetic fields respectively, which are equivalent to two magnets. At this time, the upper part of the upper conducting coil is the S pole and the lower part is the N pole, and the upper part of the lower conducting coil is the N pole and the lower part is the S pole. According to the physical principle of same-sex repulsion and opposite-sex attraction, both the upper and lower conductive coils will give the strong magnetic piston a vertical downward force, and the strong magnetic piston will move downward to the cavity in the middle of the discharge tube. The bottom of the discharge pipe is blocked to block the discharge channel and the outlet of the measuring cylinder to prevent the feed from flowing out of the storage bin and the discharge nozzle. At the same time, the liquid live feed is injected into the storage bin from the upper part of the discharge pipe through the inlet of the measuring cylinder. , until the feed fills the storage bin. Conversely, when the upper conducting coil passes through the current in the counterclockwise direction (viewed from top to bottom), and the lower conducting coil passes through the current in the clockwise direction (viewed from the top to the bottom), the upper part of the upper conducting coil is the N pole, The lower part is the S pole, the upper part of the lower conducting coil is the S pole, and the lower part is the N pole. Both the upper conducting coil and the lower conducting coil will give the strong magnetic piston a vertical upward force, and the strong magnetic piston will move upward quickly to release the force. The top of the cavity in the middle of the feeding tube pushes the liquid feed staying in the middle of the feeding tube back to the feed box, isolates the feed box from the feeding tube, blocks the feeding port of the measuring cylinder, and prevents the feed in the feeding box from flowing down. At the same time, the storage The liquid live feed in the silo flows down through the discharge opening of the measuring cylinder, and then is released from the discharge nozzle until all the feed in the storage silo flows out. The controller is connected with the upper conducting coil and the lower conducting coil respectively, and can respectively control the direction of the current flowing into the upper conducting coil and the lower conducting coil, thereby changing the magnetic field generated by the two coils and controlling the rapid upward or downward movement of the strong magnetic piston. It can realize that the feed first flows into the storage bin for constant volume, and then released from the storage bin to achieve the purpose of quantitative feeding. In addition, the constant volume of the storage bin can be changed by moving the rubber piston left and right, and the volume of a single discharge can be independently set to meet the feeding needs according to the diet of various jellyfish and the number of jellyfish. The controller has a timing function, and the feeding time and the time interval of each feeding can be set through the setting button on the controller, and the above-mentioned set time and time interval are displayed on the display screen.

When feeding, the program board controls the LED lights to turn on, and uses the phototaxis of jellyfish to induce jellyfish to swim under the feeding nozzle to feed, which can effectively improve feed utilization, reduce feed waste, and greatly reduce water pollution caused by feeding. When the liquid level of the liquid live feed in the feed box is lower than the sensor head of the water immersion sensor, the sensor head has no liquid feed as the conductive medium, the current is cut off, the water immersion sensor sends the signal to the controller, and the controller sends out an alarm through its own display screen , to remind the breeder to add feed in time.
