[0002] According to the principle of natural ecological balance, an ecological fishpond creates a natural environment where ornamental fish, algae, microorganisms, and higher aquatic plants grow in harmony. The adsorption of microalgae removes or reduces the content of nitrates and nitrites in the water, ensuring that the water entering the fishpond is clean and pollution-free. That is, cultivating microalgae also reduces the occurrence of fish diseases and simultaneously reduces the frequency of water change and the number of times of cleaning filter materials.
[0003] In the prior art, when cultivating microalgae in an ecological fishpond, the microalgae floating on the water surface are intercepted by a baffle, restricting the microalgae within the fishpond to prevent the water flow from washing away the microalgae. However, in summer, this ecological fishpond is exposed to the sun, the water level on the fishpond surface drops, and the microalgae will flow under the baffle and be discharged with the water flow. Summary of the Utility Model

[0028] Example 1
[0029] This embodiment proposes a microalgae cultivation system based on fish pond aquaculture tail water, such as Figure 1 As shown, a raceway-type culture pond 1 has a plurality of hollow partition baffles 2 slidably connected to the inner wall of the raceway-type culture pond 1, and the plurality of partition baffles 2 are equidistantly distributed in a straight line, and microalgae are cultured at the water surface of two adjacent partition baffles 2. Pretreated ammonia nitrogen wastewater flows in the raceway-type culture pond 1, and the ammonia nitrogen element contained in the wastewater is used for microalgae culture.
[0030] like Figure 2 and 3 As shown, the left end of the raceway-type breeding pool 1 is connected to a wastewater pool, and there is a gap between the bottom of the partition baffle 2 and the raceway-type breeding pool 1, through which wastewater flows, and a chute 3 is provided on the inner wall of the raceway-type breeding pool 1, and sliders 4 are fixedly installed on both the front and rear sides of the partition baffle 2, and the sliders 4 slide up and down in the chute 3. The chute 3 and the slider 4 cooperate to guide the lifting and lowering of the partition baffle 2.
[0031] The inner wall of the racetrack-type breeding pond 1 is provided with a water diversion assembly 5, which includes a lever frame 51, a water blocking plate 55 and a wastewater pool baffle 56. The first sliding column 52 is fixedly installed on both the front and rear sides of the partition baffle 2, and the second sliding column 53 is arranged on both the front and rear sides of the water blocking plate 55. The first sliding column 52 and the second sliding column 53 both slide inside the lever frame 51 to prevent the partition baffle 2 and the water blocking plate 55 from getting stuck when the lever frame 51 rotates.
[0032] The water level on the left side of the water blocking plate 55 is higher than that on the right side. A wastewater pool baffle 56 is fixedly installed on the inner wall of the raceway type breeding pond 1. The water blocking plate 55 slides up and down on the side of the wastewater pool baffle 56. When the water level drops, the partition baffle 2 moves down with the water, and the partition baffle 2 moves the water blocking plate 55 upward through the lever frame 51.
[0033] like Figure 3 As shown, a rotating shaft is fixedly installed at the frame body of the lever frame 51, and the lever frame 51 is rotatably connected to the raceway-type breeding pool 1 through the rotating shaft. A support plate is fixedly installed at the top of the raceway-type breeding pool 1, and the rotating shaft at the frame body of the lever frame 51 rotates at the support plate. The lever frame 51 is initially in a horizontal state, and there is a gap between the lever frame 51 and the raceway-type breeding pool 1. Prevent the lever frame 51 from entering the water.
[0034] In the present embodiment, in summer, the sun shines on the water in the fish pond, and the water level of the wastewater from the cultured microalgae decreases. At this time, the partition baffle 2 moves down together with the water, and the partition baffle 2 moves the water blocking plate 55 upward through the lever frame 51. Since the water level on the left side of the water blocking plate 55 is higher than that on the right side, the water on the left side of the water blocking plate 55 is introduced into the right side, and water is injected into the partition baffle 2 to replenish the water for the cultured microalgae in time, so as to prevent the height of the microalgae from being lower than the partition baffle 2, resulting in the microalgae being washed away by the water.
[0035] Example 2
[0036] Based on Example 1, this example proposes a microalgae cultivation system based on fish pond aquaculture tail water, such as Figure 4 As shown, the water blocking plate 55 includes a first slide plate 551, a buffer telescopic rod 552 and a second slide plate 553. The buffer telescopic rod 552 is fixedly installed at the bottom of the first slide plate 551, and the second slide plate 553 is fixedly installed at the bottom of the buffer telescopic rod 552. The outer wall of the second slide plate 553 is wrapped with rubber to improve the sealing effect. The first slide plate 551 slides up and down on the right side of the wastewater tank baffle 56.
[0037] When the first slide plate 551 rises and the buffer telescopic rod 552 is fully extended, the first slide plate 551 further rises to move the second slide plate 553 upward. When the wastewater surface at the partition baffle 2 fluctuates, the second slide plate 553 will not fluctuate.
[0038] The second slide plate 553 is pressed against the side of the wastewater pool baffle 56 to prevent water from flowing between the second slide plate 553 and the wastewater pool baffle 56 , and the clearance plate 54 is fixedly installed on the side of the first slide plate 551 .
[0039] In this embodiment, through the structural design of the second slide plate 553, when the partition baffle 2 drops to the set height, the partition baffle 2 drives the first slide plate 551 to rise through the lever frame 51, and the buffer telescopic rod 552 is fully extended and drives the second slide plate 553 to move upward. When the partition baffle 2 fluctuates with the wastewater surface, the buffer telescopic rod 552 acts as a buffer to prevent the second slide plate 553 from fluctuating and opening.
[0040] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
