Aquaculture system

The present invention relates to an aquaculture system, and more particularly to an aquaculture system that removes dirt from the cylinder and intermittently creates a turbulence to prevent deposits from depositing at the bottom of the cylinder.

According to the current development of the aquarium, more and more people will place fish tanks in their homes or offices to raise water and plants for viewing, improving feng shui or as a hobby. Among them, in order to keep the feeding environment in the aquarium clean, the breeder often changes the water in the aquarium regularly. For example, the Republic of China Patent Publication No. 256996 discloses an excrement collecting device provided at the bottom of an aquarium, which comprises a drain collection box, a suction pipe and a pumping motor. The waste collection box is disposed at the bottom of an aquarium, and the waste collection box has two inclined slopes which are inclined downward toward the center, and the suction pipe is installed in the center of the two inclined surfaces and connected to the pumping motor. And during the use of the waste collection device, the waste in the aquarium is slid down from the two inclined surfaces to the suction pipe by the suction force provided by the pump motor to the suction pipe, and the user can pass through the The liquid supply device continuously fills the aquarium with water, and the pumping motor is set to intermittently absorb the water containing the waste around the suction pipe. In this way, the water level in the aquarium can be changed within a certain interval by the cooperation of the liquid supply device and the pumping motor, and the waste at the bottom of the aquarium can be sucked through the pumping motor.

However, from the disclosure of the above-mentioned 256996 patent, when setting the operating condition of the pumping motor, the user needs to continuously pay attention to the water level drop in the aquarium, and The relationship between the water level drop amplitude and the actuation time or the actuation frequency of the pumping motor can be known from a plurality of settings and adjustments.

Need special instructions Yes, the siphon device 2 defines a low water mark line L1 by the position of the water level control member 24, and a high water level line H1 is defined by the position of the ㄇ type tube 22. For convenience of description, FIG. 3 to 5, 7, 8, and 11 both increase the gap between the low water mark line L1 and the high water mark line H1. However, in the actual product of the present invention, the low water level line L1 The gap with the high water mark H1 will only be close to the top of the cylinder 1 without occupying a large proportion.

In addition, the air hole 25 may be disposed at least one of the liquid inlet tube 21 or the liquid outlet tube 23, and in an embodiment, the liquid inlet tube 21 or the liquid outlet tube 23 is at least One of them has a fitting pipe 26 that provides the connection portion 241, and the air hole 25 is opened in the fitting pipe 26.

Referring to FIG. 3 to FIG. 5, in the implementation of the present invention, a liquid is stored in the cylinder 1 to feed aquatic plants (such as fish or seaweed, etc.), and the braking portion 242 is subjected to buoyancy of the liquid. The reciprocating displacement trajectory closes the air hole 25 (as shown in FIG. 3) when the braking portion 242 is swung to the first position. Specifically, when the braking portion 242 floats on the liquid, the buoyancy structure 243 floats through the air chamber 245 and floats on the liquid, and the abutting surface 246 is closed to the air hole 25. Based on the foregoing state, the user can continuously inject the liquid from the filter cylinder 3 into the cylinder 1 through a liquid extracting member 31, so that the cylinder 1 and the liquid in the liquid inlet tube 21 rise simultaneously, and When the liquid rises to the high water mark H1 and the liquid flows out of the liquid discharge pipe 23, the siphon device 2 enters a first state in which a siphon action is generated (as shown in FIG. 4). In detail, the first state means that the liquid will continue to flow out (ie, the siphon action) from the outlet pipe 23 which is lower than the liquid inlet pipe 21 to drive the liquid inlet pipe 21 to continuously extract the cylinder block 1 The liquid inside is used to remove the waste such as aquatic animal waste or external dirt in the cylinder 1. Further, the liquid outlet tube 23 can extend into the filter cylinder 3, and the filter cylinder 3 can be provided with a filter layer (not shown), so that the liquid discharge tube 23 discharges the waste containing material. The liquid can be filtered through the filter layer, and then The liquid suctioning member 31 replenishes the filtered liquid into the cylinder block 1. When the liquid in the cylinder 1 is lowered by the siphon action of the siphon device 2 to the low water line L1, the siphon device 2 then enters a second state. In detail, the second state means that the braking portion 242 swings to the second position during the reciprocating displacement trajectory due to the loss of some or all of the buoyancy of the liquid. The braking portion 242 releases the air hole 25 (as shown in FIG. 5), so that external air enters the liquid inlet tube 21 from the air hole 25 to destroy the siphoning action, thereby stopping the liquid inlet tube 21 to continuously suck the cylinder body 1 The liquid of the booty. When the siphon device 2 stops discharging the liquid, the liquid in the cylinder 1 will rise to the high water mark H1 with the replenishment of the liquid extracting object 31 to drive the siphon device 2 to enter the first status. In this way, the siphon device 2 can be switched between the first state and the second state, so that the liquid in the cylinder 1 can be between the high water mark H1 and the low water line L1. A rapid fluctuation similar to the tidal phenomenon is generated, and at the same time, the liquid is intermittently sucked through the siphon device 2, thereby sucking the dirt in the cylinder 1 and intermittently generating a turbulence to prevent deposits from depositing on the bottom of the cylinder 1. Furthermore, the user can directly adjust the height of the water level control member 24 to change the position of the low water mark line L1, thereby changing the falling range of the liquid to meet the volume setting or use requirement of the cylinder block 1, thereby solving the problem. The implementation uses an overly cumbersome problem.
