Detailed Description
As shown in figures 1-3, the experimental device for symbiosis of mangrove and marine fish for teaching comprises a main body frame 1, a marine fish culture box 2, a mangrove cultivation box 3 and an intelligent control device.
The intelligent control device 5 comprises a single-chip microcomputer main controller 6, a touch display screen 7, a water quality monitoring sensor 8, an LED lighting lamp tube 9 and a submersible pump 10. The touch display screen 7 and the water quality monitoring sensor 8 are respectively connected with the singlechip main controller 6; the LED lighting lamp tube 9 and the submersible pump 10 are respectively connected with the singlechip main controller 6 through a relay 11 and a relay 12.
The main body frame 1 is formed by assembling stand columns and three layers of partition plates, the marine fish culture box 2 and the mangrove cultivation box 3 are respectively placed on the bottom layer partition plate and the middle layer partition plate of the main body frame 1, and the LED lighting lamp tube 9 is fixedly installed on the bottom surface of the upper layer partition plate. The water quality monitoring sensor 8 and the submersible pump 10 are respectively arranged in the marine fish culture box 2, and a water outlet pipe of the submersible pump 10 extends to the upper part of the inner cavity of the mangrove culture box. A siphon drainage device 4 is arranged in the mangrove cultivation box 3, and a water outlet of the siphon drainage device 4 is arranged above the marine fish cultivation box 2. The immersible pump 10 is taken out the sea water in the sea fish breed case 2 to mangrove cultivation case 3, when the liquid level in the mangrove cultivation case 3 reached the take the altitude, then through siphon drainage device arrange the sea fish breed in the case 2, so the design, can simulate the environment of morning and evening tides.
Further, the water quality monitoring sensor 8 comprises a PH sensor 81, an ammonia nitrogen sensor 82 and a temperature sensor 83. The LED lighting lamp tubes 9 are provided with 6 LED lighting lamp tubes which are arranged side by side and are uniformly distributed and fixed on the bottom surface of the upper layer clapboard.
The touch display screen 7 can display the current time in real time and display data measured by the PH sensor 81, the ammonia nitrogen sensor 82 and the temperature sensor 83. The starting or stopping of the submersible pump 10 and the turning on and off of the LED lighting lamp tube 9 can be controlled manually and in a touch mode.
Preferably, the main body frame 1 is made of stainless steel and coated with a coating for preventing seawater corrosion, thereby prolonging the service life.
Specifically, as shown in fig. 4-6, a mounting hole has been seted up on the mangrove cultivation case 3 bottom surface, siphon drainage device 4 includes overflow pipe 41, outlet pipe 42 and the siphon cover 43 of cover in overflow pipe upper portion outside, is equipped with bar water inlet 431 on the opening part lateral wall of siphon cover 43, and the pipe wall and the mounting hole pore wall sealing connection of mounting hole and overflow pipe are passed to overflow pipe 41 lower part, and outlet pipe 42 is zigzag and one end and overflow pipe 41 lower extreme threaded connection.
The siphon drainage device works as follows: 1. when the submersible pump 10 operates, the water in the marine fish culture tank 2 is pumped to the mangrove cultivation tank 3, the water level of the mangrove cultivation tank 3 begins to rise, water enters the cavity between the siphon cover 43 and the overflow pipe 41 from the strip-shaped water inlet 431 at the bottom of the siphon cover 43, and when the water level continues to rise to the opening of the overflow pipe 41, the water overflows downwards from the opening of the overflow pipe 41. 2. When water flows out from the opening at the other end of the overflow pipe 41, the exchange between the atmosphere in the gap between the siphon cover 43 and the overflow pipe 4-2 and the external atmosphere is blocked, meanwhile, when the submersible pump 10 continuously operates, the water level of the mangrove cultivation box 3 continuously rises, and the water continuously enters the cavity between the siphon cover 43 and the overflow pipe 41 and flows down from the opening at the top of the overflow pipe 41; thus, when water flows down from the opening, the air pressure in the cavity between the siphon bell 43 and the overflow pipe 41 is reduced, and then the siphon effect is caused, so that more water is discharged downwards from the opening of the overflow pipe 41 and circulates. Until the water level of the mangrove cultivation box 3 is lowered to the strip-shaped opening of the water blocking pipe 4-1, the air pressure in the cavity between the siphon hood 43 and the overflow pipe 41 is balanced with the atmospheric pressure outside the siphon hood 43, the siphon action is stopped, and the water is stopped to be discharged downwards from the opening of the overflow pipe 41. 3. When the water level rises again, the return 1 process enters the next siphon cycle.
