Description

Technical Field

[0001] This invention relates to the field of aquaculture systems, and more specifically to a turtle farming pond system with bottom drainage function. Background Technology

[0002] With the continuous development of aquaculture and the increasing stocking density, the pursuit of high-yield and high-efficiency aquaculture measures has caused great pollution to the aquaculture water environment, especially the bottom environment of ponds, and has destroyed the original ecological balance of ponds.

[0003] In turtle farming, it's inevitable that uneaten feed and aquatic organism excrement will not be promptly removed from the pond. Over time, these substances decompose and decompose, causing water quality deterioration. This leads to abnormal changes in nutrients such as nitrogen (N) and phosphorus (P), producing toxic substances like ammonia nitrogen, hydrogen sulfide, and nitrite. This results in eutrophication, increased algae growth, and decreased dissolved oxygen, among other complications. Pond water pollution slows turtle growth, reduces turtle quality, and in severe cases, can cause disease and death. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems by providing a turtle farming pond system with bottom drainage function, which can promptly and conveniently separate the sediment from the bottom of the pond into the farming water, thereby ensuring the health of the farming water.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a turtle farming pond system with bottom drainage function, comprising a pond body, the bottom of which is pot-shaped, and a geomembrane covering the surface of the pond body. A sludge collection tank is located at the lowest point in the center of the pond body, the bottom of which is inverted cone-shaped, and the upper end of which is connected to the geomembrane. A screen is installed at the upper end of the sludge collection tank. A suction pipe is arranged along the upper or lower surface of the geomembrane, one end of which is located in the center of the sludge collection tank near the bottom, and the other end is connected to a wastewater treatment device on the pond bank. A point-type bottom aeration device is installed on the upper surface of the geomembrane, and an exhaust device is installed on the lower surface of the geomembrane. Water-pushing aerators are arranged clockwise or counterclockwise at the four corners of the pond body, and a floating plant bed is installed at the rear end of each water-pushing aerator.

[0006] Furthermore, the point-type bottom aeration device includes a blower, a main air supply pipe, a large plug, a self-sinking pipe, a perforated connecting pipe, a nano-aeration pipe, and a small plug. The main air supply pipe is located on one side of the bank of the main body of the pond. One end of the main air supply pipe is connected to the blower, and the other end is connected to the large plug. The self-sinking pipe is arranged parallel to the upper surface of the geomembrane. One end of the self-sinking pipe is connected to the main air supply pipe, and the other end is connected to the small plug. The perforated connecting pipe is arranged at equal intervals along the self-sinking pipe. Both ends of the perforated connecting pipe are connected to the self-sinking pipe. The nano-aeration pipe is fitted onto the outside of the perforated connecting pipe.

[0007] Furthermore, the exhaust device includes an air pump, an air extraction pipe, and a perforated air extraction branch pipe. The perforated air extraction branch pipe is annular and is located on the lower surface of the geomembrane and connected to the lower surface of the geomembrane. The air pump is located on one side of the bank of the main body of the pond, and the air extraction pipe is located on the lower side of the geomembrane. One end of the air extraction pipe is connected to the air pump, and the other end is connected to the perforated air extraction branch pipe.

[0008] Furthermore, the thickness of the geomembrane is 0.5 mm to 1.5 mm, preferably 0.9 mm.

[0009] Furthermore, the slope of the bottom of the main body of the pond is 2.0% to 5.0%, with a preferred slope of 3.0%.

[0010] The turtle breeding pond system with bottom drainage function of the present invention has the following beneficial effects: (1) The present invention only requires simple modification of the existing turtle breeding pond. With the help of a water pusher and aerator, the feed residue, aquatic organism excrement and other waste in the breeding water can be collected in the sludge collection pond in the center of the breeding pond. The waste sediment in the sludge collection pond can be promptly removed from the breeding water by the tailwater treatment device on the shore of the pond, thereby reducing the purification burden of the pond itself, reducing environmental pollution, and increasing the breeding density and survival rate.

[0011] (2) The point bottom oxygenation device of the present invention can uniformly oxygenate multiple points in the entire aquaculture pond, making oxygenation more efficient and ensuring the oxygen content of the aquaculture water.

[0012] (3) The smooth surface of the geomembrane of the present invention is conducive to the gathering of aquaculture waste into the central sewage collection pond. At the same time, the geomembrane can prevent water leakage in the aquaculture pond and save water resources.

[0013] (4) The exhaust device of the present invention can extract the gas released from the bottom of the pond under the geomembrane to prevent the geomembrane from bulging. Attached Figure Description

[0018] The present invention will now be further described in conjunction with embodiments and accompanying drawings to provide a full understanding of its purpose, features, and effects.

[0019] Example 1: As Figures 1-3 As shown, a turtle farming pond system with bottom drainage function includes a pond body 1, the bottom of which is pot-shaped, and a geomembrane 2 is laid on the surface of the pond body 1. A sludge collection tank 6 is set at the lowest point in the center of the pond body 1. The bottom of the sludge collection tank 6 is inverted cone-shaped, and the upper end of the sludge collection tank 6 is connected to the geomembrane 2. A screen 7 is set at the upper end of the sludge collection tank 6, and a suction pipe 8 is arranged along the upper or lower surface of the geomembrane 2. One end of the suction pipe 8 is... The wastewater collection tank 6 is located in the center near the bottom, and the other end is connected to the tailwater treatment device 10 on the pond bank. The point-type bottom aeration device 5 is set on the upper surface of the geomembrane 2, and the exhaust device 9 is set on the lower surface of the geomembrane 2. The four corners of the main body of the pond are equipped with water-pushing aerators 3 arranged in a counterclockwise direction. The rear end of the water-pushing aerators 3 is equipped with a plant floating bed 4. The thickness of the geomembrane 2 is 0.9 mm, and the slope of the bottom of the main body of the pond 1 is 3.0%.

[0020] The point-type bottom aeration device 5 includes a blower 51, an air supply main pipe 52, a large plug 53, a self-sinking pipe 54, a perforated connecting pipe 55, a nano-aeration pipe 56, and a small plug 57. The air supply main pipe 52 is located on one side of the bank of the main body of the pond 1. One end of the air supply main pipe 52 is connected to the blower 51, and the other end is connected to the large plug 53. The self-sinking pipe 54 is arranged parallel to the upper surface of the geomembrane 2. One end of the self-sinking pipe 54 is connected to the air supply main pipe 52, and the other end is connected to the small plug 57. The perforated connecting pipe 55 is arranged at equal intervals along the self-sinking pipe 54. Both ends of the perforated connecting pipe 55 are connected to the self-sinking pipe 54. The nano-aeration pipe 56 is fitted onto the outside of the perforated connecting pipe 55.

[0021] The exhaust device 9 includes an air pump 91, an air extraction pipe 92, and a perforated air extraction branch pipe 93. The perforated air extraction branch pipe 93 is annular and is located on the lower surface of the geomembrane 2 and connected to the lower surface of the geomembrane 2. The air pump 91 is located on one side of the bank of the pond body 1, and the air extraction pipe 92 is located on the lower side of the geomembrane 2. One end of the air extraction pipe 92 is connected to the air pump 91, and the other end is connected to the perforated air extraction branch pipe 93.

[0022] The working principle of a turtle farming pond system with bottom drainage function according to the present invention is as follows: the water-pushing aerators 3 at the four corners of the main body of the pond 1 push the aquaculture water in the pond to flow slowly in a counterclockwise direction, forming a circular water flow, which carries the uneaten feed, aquatic organism excrement and other sedimentable aquaculture waste in the aquaculture water to the collection pond 6; the plant floating bed 4 at the rear end of the water-pushing aerator 3 plays a certain role in purifying the aquaculture water in the pond; the net 7 at the upper end of the collection pond 6 can prevent the farmed turtles and other animals from entering the collection pond 6 and stirring up the already settled aquaculture solid waste.

[0023] When the amount of aquaculture solid waste in the collection pond 6 reaches a certain level, the tailwater treatment device 10 on the pond bank can be activated to promptly remove the aquaculture solid waste from the aquaculture water body through the suction pipe 8, thus preventing it from polluting the water body.

[0024] When the oxygen content of the aquaculture water is insufficient, the blower 51 of the point-type bottom aeration device 5 is activated to compress air into the air supply main pipe 52. The air enters the self-sinking branch pipe 54 through the air supply main pipe 52, and then enters the perforated connecting pipe 55 along the self-sinking branch pipe 54. The air in the perforated connecting pipe 55 then enters the nano-oxygenation pipe 56 through the holes on the perforated connecting pipe 55. After being broken down by the numerous micropores on the nano-oxygenation pipe 56, the air enters the water and forms numerous small bubbles, which fully contact and dissolve with the water to achieve the purpose of increasing the dissolved oxygen in the water.

[0025] At certain time intervals, the exhaust pump 91 of the exhaust device 9 is activated. The gas released from the bottom of the pond under the geomembrane 2 enters the perforated exhaust branch pipe 93 through the evenly distributed small holes on the perforated exhaust branch pipe 93, and then enters the exhaust pipe 92. It is then discharged into the atmosphere through the exhaust pump 91 to prevent the geomembrane 2 from bulging due to too much gas accumulating at the bottom.

[0026] The above description is only a specific embodiment of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
