Description

Technical Field

[0001] This invention relates to the field of land-based aquaculture technology, specifically to an energy-saving, automatic siphon-type sewage discharge land-based circular pond. Background Technology

[0002] my country's aquaculture industry has developed rapidly, and people's demand for the nutrition and quality of aquatic products is increasing, making it the world's largest aquaculture country. However, traditional pond aquaculture and methods such as cage and enclosure netting in rivers and reservoirs generally have many problems, such as large land area requirements, serious pollution of aquaculture wastewater, eutrophication, high disease rates in aquatic animals, and poor controllability. These problems are not conducive to the transformation of my country's aquaculture towards green, healthy, and high-quality development. Therefore, there is an urgent need for a new type of green and energy-saving aquaculture equipment and management model. Land-based circular pond aquaculture has been systematically promoted in many places in the past two years due to its advantages such as small land area, no influence from topography, no damage to land properties, and high degree of intensification and intelligence.

[0003] Water pollution has always been a major problem in aquaculture. High-density farming can easily lead to water pollution due to uneaten feed and excrement from fish and shrimp. Therefore, frequent sewage discharge is necessary. Flat-bottomed aquaculture ponds make it difficult to centrally discharge sewage. If the pond is large, the fish and shrimp move around, causing the excrement to scatter, which greatly reduces the efficiency of the system's sewage discharge. Currently, the common method is to use water pumps to filter out the excrement, which increases the daily electricity cost of the aquaculture farm. In addition, due to the high stocking density, some weak and diseased fish and shrimp will inevitably die. Usually, dead fish are manually removed using nets. However, aquaculture ponds are generally deep, which increases the difficulty of removal. Currently, there is a lack of devices for collecting and regularly discharging the collected excrement.

[0004] To solve the above problems, it is necessary to provide an energy-saving automatic siphon-type land-based circular sewage tank. Summary of the Invention

[0005] To solve the above-mentioned technical problems, an energy-saving automatic siphon-type sewage discharge land-based circular pond is provided. This technical solution solves the problem mentioned in the background technology that the electricity cost of using a water pump to filter out excrement is extremely high. In addition, due to the high stocking density, some weak and diseased fish or fry will always die. It is common to manually use nets to catch fish or fry, and the fact that the breeding pond is generally deep increases the difficulty of catching.

[0035] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0036] Reference Figure 1-8 As shown, an energy-saving automatic siphon-type land-based circular sewage discharge tank includes:

[0037] The land-based circular pool body 102 has two supporting columns 101 fixedly connected to its right side.

[0038] The siphon mechanism 300 is located inside the upper right side of the land-based circular pool body 102. The siphon mechanism 300 is used to siphon the excrement and dead fish accumulated at the bottom of the land-based circular pool body 102.

[0039] A lifting mechanism 200 is installed on the top of the support column 101. A siphon mechanism 300 is hung at the bottom of the lifting mechanism 200. The lifting mechanism 200 is used to lift and dump the excrement and dead fish in the siphon mechanism 300.

[0040] Reference Figure 3 and Figure 5Specifically, the lifting mechanism 200 includes a working platform 201. Two lower take-up rollers 205 are rotatably connected to the center of the upper surface of the working platform 201. The lower take-up rollers 205 are symmetrically distributed on both sides of the working platform 201. An upper take-up roller 204 is fixedly connected to the top of each lower take-up roller 205. A secondary bevel gear 209 is fixedly connected to the top of each upper take-up roller 204. Two fixing blocks 202 are fixedly connected to the front and rear sides of the lower take-up rollers 205 on the working platform 201. The fixing blocks 202 are symmetrically distributed on the front and rear sides of the lower take-up rollers 205. A guide pulley 208 is rotatably connected between the two fixing blocks 202. A square hole 203 is provided through the platform 201 near the guide pulley 208. The square hole 203 is located on the outside of the guide pulley 208. A lifting rope 206 is installed on the surface of the lower take-up roller 205 and the upper take-up roller 204. The lifting rope 206 on the surface of the lower take-up roller 205 is guided from the left to the front guide pulley 208, and the lifting rope 206 on the surface of the upper take-up roller 204 is guided from the right to the rear guide pulley 208. The lifting rope 206 extends downward through the square hole 203, and a lifting arm 107 is fixedly connected to the bottom end of the lifting rope 206.

[0041] Two support plates 213 are fixedly connected to the upper surface of the work platform 201. A driven rod 207 is rotatably connected to the top of the support plate 213. A driven bevel gear 210 is fixedly connected to the rear end of the driven rod 207. The driven bevel gear 210 meshes with the secondary bevel gear 209. A conical transmission wheel 211 is fixedly connected to the front end of the driven rod 207. Two driving rods 214 are rotatably connected to the front side of the upper surface of the work platform 201. A main bevel gear 212 is fixedly connected to the top of the driving rod 214. The main bevel gear 212 meshes with the conical transmission wheel 211. A rotating handle 215 is fixedly connected to the bottom end of the driving rod 214.

[0042] Reference Figure 5 , Figure 6 and Figure 7 In use, turning the rotating handle 215 drives the upper take-up roller 204 and lower take-up roller 205 to rotate via the transmission of the main bevel gear 212, bevel transmission wheel 211, driven bevel gear 210, and secondary bevel gear 209. This causes the upper take-up roller 204 and lower take-up roller 205 to take in the lifting rope 206, thereby moving the siphon mechanism 300 away from the land-based circular pool body 102. When the siphon mechanism 300 has risen to a sufficient height, stop turning the right rotating handle 215 and continue turning the left rotating handle 215. The siphon mechanism 300 will then tilt, and the movable guide plate 316 will rotate to the right and tilt. Figure 6As shown, the movable guide plate 316 is supported by the protruding part of the bottom surface of the siphon trough 307, and the excrement in the siphon mechanism 300 will be poured out. If there is no movable guide plate 316, some excrement will flow into the land-based circular pool body 102 due to the tilting of the siphon trough 307. Then, the siphon mechanism 300 is lowered to its original position, and the movable guide plate 316 is lifted to its original position by the rotation of the edge of the land-based circular pool body 102. The limiting strip 313 limits the position of the movable guide plate 316. The top of the siphon pipe 309 is blocked by related components, which will be explained later.

[0043] Reference Figure 3 , Figure 6 and Figure 7 The siphon mechanism 300 includes a siphon groove 307. Several lifting arms 107 are fixedly connected to the top of the siphon groove 307. The lifting arms 107 are connected to lifting ropes 206. Two inclined supports 312 are fixedly connected to the bottom surface inside the siphon groove 307. A working disc 306 is fixedly connected between the two inclined supports 312. A rotating rod 305 is rotatably connected to the middle of the working disc 306. A rotating arm 304 is fixedly connected to the top of the rotating rod 305. A swing arm 318 is fixedly connected to the bottom of the rotating rod 305. A transmission frame 401 is rotatably connected to the end of the transmission frame 401. A siphon tube 309 is fixedly connected to the bottom of the transmission frame 401. A large opening is provided on the bottom surface of the siphon groove 307. A rubber elastic membrane 317 is fixedly connected to the large opening. The rubber elastic membrane 317 is fixedly connected to the top end of the siphon tube 309. Two auxiliary mounting plates 311 are fixedly connected to the bottom of the siphon groove 307. A rotating frame 310 is rotatably connected between the two auxiliary mounting plates 311. A positioning shaft 308 is rotatably connected to the middle of the side of the rotating frame 310. The positioning shaft 308 is fixedly connected to the siphon tube 309.

[0044] A positioning slide rod 302 is slidably connected to the end of the rotating arm 304. Several limiting holes 303 are opened on the surface of the working disc 306. The limiting holes 303 are evenly distributed around the circumference of the working disc 306. The bottom end of the positioning slide rod 302 is slidably connected in the limiting hole 303. A return spring 301 is sleeved on the upper part of the positioning slide rod 302. The top end of the return spring 301 is fixedly connected to the top end of the positioning slide rod 302. The bottom end of the return spring 301 is fixedly connected to the upper surface of the rotating arm 304.

[0045] A movable guide plate 316 is installed on the right side of the siphon trough 307. The bottom end of the movable guide plate 316 is rotatably connected to the siphon trough 307. The front and rear ends of the movable guide plate 316 abut against the inner wall of the siphon trough 307. A limit strip 313 is fixedly connected to the right side of the inner wall of the siphon trough 307. The right side of the limit strip 313 abuts against the left side of the movable guide plate 316. The bottom surface of the siphon trough 307 extends slightly to the outside of the movable guide plate 316.

[0046] The bottom of the siphon 307 is slidably connected to an outlet pipe 315. The bottom end of the outlet pipe 315 bends and extends to the main body 102 of the land-based circular pool. The outlet pipe 315 is supported and connected to the main body 102 of the land-based circular pool. A filter screen 314 is fixedly connected to the siphon 307 at the position of the outlet pipe 315. Several holes are opened on the surface of the filter screen 314. The filter screen 314 is sleeved on the outside of the top end of the outlet pipe 315. The lower surface of the filter screen 314 is a sealed structure.

[0047] The siphon pipe 309 connects the bottom of the land-based circular pool body 102 and the siphon trough 307 at both ends. When the amount of excrement in the water reaches a certain level, the water inlet pipe 105 is opened to release water, and the water level in the land-based circular pool body 102 rises. Utilizing the liquid level difference, the end of the siphon pipe 309 near the bottom of the land-based circular pool body 102 siphons the excrement that has settled at the bottom into the siphon trough 307. In addition to its sewage discharge function, it also siphons weak or dead fish into the siphon trough 307, making it easier to remove dead fish.

[0048] The siphon tube 309 can move slightly. Farmers can move the position of the tube opening within a certain range according to the bottom of the breeding pond. The positioning slide rod 302 can be pulled out from the limiting hole 303, and the rotating arm 304 can be rotated, which in turn drives the swing arm 318 to rotate. Then the transmission frame 401 will rotate around the rotating rod 305 as the axis. The rubber elastic membrane 317 is elastic. At the same time, the positioning shaft 308 and the rotating frame 310 will cooperate to assist the movement of the siphon tube 309.

[0049] The siphon trough 307 is a semi-enclosed trough located at the top edge of the main body 102 of the land-based circular pond. It is open to the outside atmosphere, allowing fish farmers to easily observe the water turbidity at the bottom of the pond and remove dead fish. The siphon trough 307 has two openings, connected to a siphon pipe 309 and an outlet pipe 315, respectively. The height of the siphon pipe 309 opening is lower than the height of the outlet pipe 315 opening, which in turn is lower than the height of the siphon trough 307. When water enters, the water level in the main body 102 of the land-based circular pond rises. Due to the difference in water levels, wastewater from the bottom of the pond continuously flows into the siphon trough 307, causing the water level to rise to the outlet pipe 315 opening, at which point the wastewater is discharged through the outlet pipe 315.

[0050] The filter screen 314 is nested around the water outlet pipe 315. The height of the filter screen 314 is higher than that of the water outlet pipe 315. It is used to intercept dead fish that are siphoned into the siphon tank 307 and prevent the water outlet pipe 315 from being blocked.

[0051] Reference Figure 8A positioning plate 403 is fixedly connected to the left side of the transmission frame 401. A drive screw 402 is rotatably connected to the middle of the positioning plate 403. A guide groove 405 is opened through the left side of the transmission frame 401. A guide block 404 is slidably connected in the guide groove 405. The guide block 404 is threadedly connected to the lower part of the drive screw 402. A sealing rubber plug 406 is fixedly connected to the right side of the guide block 404. The sealing rubber plug 406 is located in the middle of the transmission frame 401. The shape of the sealing rubber plug 406 is consistent with the shape of the opening of the siphon tube 309.

[0052] When the siphon trough 307 is raised, the drive screw 402 is turned first, causing the sealing rubber plug 406 to descend and block the top of the siphon pipe 309, preventing the excrement from flowing back into the land-based circular pool body 102 when the siphon trough 307 rises.

[0053] A fixing plate 106 is fixedly connected to the upper left of the main body 102 of the land-based circular pool. A water inlet pipe 105 is fixedly connected to the middle of the fixing plate 106. A water outlet is connected to the bottom of the water inlet pipe 105. The water outlet is tangential to the circumference of the main body 102 of the land-based circular pool. A screen 108 is fixedly connected to the bottom of the main body 102 of the land-based circular pool. Several holes are opened on the surface of the screen 108. A sludge collection tank 103 is fixedly connected to the bottom of the screen 108. The sludge collection tank 103 has a hollow structure. A sewage discharge pipe 104 is fixedly connected to the bottom of the sludge collection tank 103.

[0054] A circular sludge collection tank 103 is provided at the bottom of the main body 102 of the land-based circular pool, and a siphon groove 307 is provided at the top edge. A sludge outlet is provided at the bottom of the sludge collection tank 103, and the sludge outlet is connected to a sludge pipe 104. A screen 108 is placed above the sludge collection tank 103 to prevent fish or fish fry from accidentally running into the sludge pipe 104. The height of the pipe opening of the siphon pipe 309 near the siphon groove 307 is lower than the height of the outlet pipe 315. The height of the outlet pipe 104 is lower than the height of the outlet pipe 315. A filter screen 314 is nested outside the outlet pipe 315. The height of the filter screen 314 is higher than the height of the outlet pipe 315. The inlet pipe 105 runs along the edge of the main body 102 of the land-based circular pool and its direction is tangent to the main body 102 of the land-based circular pool.

[0055] The main body 102 of the land-based circular pool is divided into two parts. The upper part is cylindrical to facilitate water flow, while the lower part is conical to facilitate the natural settling and accumulation of fish excrement.

[0056] The inlet pipe 105 is located at the edge of the land-based circular pool body 102, away from the siphon trough 307 and below the water surface. The bottom opening of the inlet pipe 105 is tangent to the land-based circular pool body 102. When water is introduced, a jet will be generated, which will drive the water in the land-based circular pool body 102 to rotate and flow in the same direction along the circular barrel wall. Through the principle of rotating and collecting sewage, the excrement in the land-based circular pool body 102 is collected into the sewage collection tank 103.

[0057] A perforated screen 108 is placed on the upper part of the sludge collection tank 103. The size of the screen 108 is smaller than that of the farmed fish or fry, in order to prevent the fish or fry from accidentally running into the sewage pipe 104. It can be replaced according to the different sizes of the farmed fish or fry.

[0058] The sewage pipe 104 extends upward along the outside of the land-based circular pool body 102. The top of the sewage pipe 104 is U-shaped, and its opening height is lower than that of the water outlet pipe 315. Utilizing the U-shaped pipe principle, when water is introduced, the water level in the land-based circular pool body 102 is higher than the opening height of the pipe. The excrement accumulated at the bottom of the land-based circular pool body 102 will be discharged with the water flow. After the water is stopped, the water level in the sewage pipe 104 will slowly become level with the water surface in the land-based circular pool body 102.

[0059] The working principle and usage process of this invention are as follows: By setting up a sewage pipe 104, a lifting mechanism 200, and a siphon mechanism 300, the sewage pipe 104 can siphon excrement to the outside of the land-based circular pond body 102, the siphon mechanism 300 can siphon dead fish and large excrement particles into the siphon trough 307, the lifting mechanism 200 can lift the siphon mechanism 300 and tilt the siphon mechanism 300, and discharge the dead fish and excrement inside the siphon mechanism 300 from the land-based circular pond body 102. This siphon sewage discharge mode can greatly save the electricity cost of aquaculture. The design of the inlet and conical bottom of the water inlet pipe 105 makes it easier for excrement to settle and concentrate in the sewage collection tank 103 and enter the sewage pipe 104, which can efficiently control water quality and improve the survival rate of fish or fry.
