Description

Technical Field

[0001] This invention relates to the field of aquaculture, and in particular to a water circulation device for fish farming. Background Technology

[0002] Aquaculture ponds are artificial structures used to raise aquatic economic crops such as fish and shrimp. During the rearing process, fish excrement and uneaten fish feed will sink to the bottom of the pond and need to be cleaned in a timely manner. Generally, equipment that cleans excrement and feed through water circulation is used. After the water moves and collides with each other, the oxygen content in the pond water is greatly reduced. Directly discharging this into the aquaculture pond will cause the oxygen content of the pond water to drop rapidly, which can easily cause stress reactions in the fish and, in severe cases, lead to fish death.

[0003] Therefore, a fish recirculating aquaculture pond with patent number CN221241330U has been developed. While this device solves the above problems, it has the following drawbacks: the fixed sewage pipe makes it difficult to extract particulate impurities that have settled in different areas at the bottom of the pond, thus affecting the cleaning efficiency and effect of impurities at the bottom of the pond. At the same time, after the filter plate filters the liquid containing impurities for a long time, the impurities will accumulate on the top surface of the filter plate and block it. If the filter plate is not cleaned immediately, the accumulation and blockage of the filter plate will undoubtedly affect the filtration efficiency and effect of the liquid. Summary of the Invention

[0004] The purpose of this invention is to provide a water circulation device for fish farming.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A water circulation device for fish farming includes a pond body with a grid plate installed inside the pond. A debris removal mechanism and a cleaning mechanism driven by a motor are respectively installed on the upper and lower sides of the grid plate within the pond body. The motor and the debris removal mechanism are connected via a transmission mechanism. A box body is also installed on one side of the pond body. The top of the pond body and the bottom of the box body are connected via a circulation pipe equipped with a water pump I. The cleaning mechanism is connected to the box body via a connecting pipe equipped with a water pump II. A filtration mechanism is also installed inside the box body.

[0007] The cleaning mechanism includes a lead screw I driven by a motor. A strip seat for the lead screw I to pass through is provided at the bottom of the pool body. A cavity is provided inside the strip seat. A strip plate is provided at the bottom of the strip seat. Water suction holes communicating with the cavity are provided at the bottom of the strip seat on both sides of the strip plate. The cavity is connected to a connecting pipe through a corrugated hose.

[0008] Preferably, the filtration mechanism includes a cylindrical section located at the top of the housing and sealed at both ends. A cylindrical section extends into the housing from within the cylindrical section. A bearing for fixing the cylindrical section is provided on the top wall of the housing. Multiple sets of push plates are radially arranged on the cylindrical section. The connecting pipe is tangentially arranged to the cylindrical section. A recovery pipe extends into the housing from the cylindrical section. A filter basket is provided at the bottom end of the cylindrical section inside the housing. An annular seat is provided at the top of the housing and fitted onto the filter basket. A groove is arranged around the inner side wall of the annular seat. A slider located within the groove is provided at the top of the outer wall of the filter basket.

[0009] Preferably, a support base for fixing the motor is provided on the outside of the pool body, the impurity removal mechanism includes a perforated plate arranged longitudinally at the top of the pool body, a sliding rod I arranged transversely in the pool body passing through a sliding hole on the perforated plate, a protruding plate is also provided on the top of the perforated plate, the protruding plate is provided with a screw hole for screwing to lead screw II, one end of lead screw II extends to the outside of the pool body, and the transmission mechanism includes a pulley arranged at the end of lead screw II and on the output shaft of the motor, wherein the upper and lower sets of pulleys are connected by a transmission belt.

[0010] Preferably, an installation pipe is provided on one side of the top of the pool body, and drainage pipes located above the impurity removal mechanism are evenly arranged at the bottom of the installation pipe, and the circulation pipe is connected to the installation pipe.

[0011] Preferably, the top of the strip seat is provided with a boss, the boss is provided with a screw hole for screwing the lead screw I, and the pool body is also provided with a slide rod II that passes through the slide hole on the boss.

[0012] Preferably, the bottom end of the strip plate is attached to the bottom wall of the pool, and through holes are evenly distributed on the side wall of the strip plate.

[0013] The beneficial effects of this invention are as follows: This invention uses a motor-driven cleaning mechanism to reciprocate, causing the strip plate in the cleaning mechanism to scrape off the sediment at the bottom of the tank and mix it with the liquid. At the same time, the water pump II works to extract the liquid mixed with impurities through the connecting pipe, the corrugated hose, the cavity, and the water extraction hole in the cleaning mechanism, thereby improving the cleaning effect and efficiency of sediment at the bottom of the tank. Simultaneously, the extracted liquid is introduced into the cylinder in the filtration mechanism, which pushes the push plate inside the cylinder and drives the rod and filter basket to rotate. At this time, the liquid in the cylinder flows into the filter basket through the recovery pipe. While the filter basket filters the impurities in the liquid, the rotating filter basket causes the impurities inside to generate centrifugal force with the liquid, which accelerates the filtration efficiency of the liquid inside and effectively prevents the impurities from settling and clogging the side wall pores of the filter basket during the filtration process, thus affecting the filtration work.

[0019] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] A water circulation device for fish farming includes a pond body 1, a grid plate 2 installed inside the pond body 1, a debris removal mechanism 3 and a cleaning mechanism 5 driven by a motor 4 respectively installed on the upper and lower sides of the pond body 1, the motor 4 and the debris removal mechanism 3 are connected through a transmission mechanism 6, a box body 7 is also installed on one side of the pond body 1, the top of the pond body 1 and the bottom of the box body 7 are connected by a circulation pipe 9 with a water pump I8 installed, the cleaning mechanism 5 is connected to the box body 7 through a connecting pipe 11 with a water pump II10 installed, and a filter mechanism 12 is also installed inside the box body 7;

[0021] The cleaning mechanism 5 includes a lead screw I51 driven by a motor 4. A strip seat 52 for the lead screw I51 to pass through is provided at the bottom of the pool body 1. A cavity 53 is provided inside the strip seat 52. A strip plate 54 is provided at the bottom of the strip seat 52. Water suction holes 55 communicating with the cavity 53 are provided at the bottom of the strip seat 52 on both sides of the strip plate 54. The cavity 53 is connected to the connecting pipe 11 through a corrugated hose 56.

[0022] The filtration mechanism 12 includes a cylindrical tube 121 located at the top of the housing 7 and sealed at both ends. A cylindrical rod 122 extending into the housing 7 is disposed inside the cylindrical tube 121. A bearing for fixing the cylindrical rod 122 is disposed on the top wall of the housing 7. Multiple sets of push plates 123 are radially disposed on the cylindrical rod 122 inside the cylindrical tube 121. The connecting pipe 11 communicates with the cylindrical tube 121 and the two are tangentially disposed thereto. A recovery pipe 124 extending into the housing 7 is also disposed on the cylindrical tube 121. A filter basket 125 is disposed at the bottom end of the cylindrical rod 122 inside the housing 7. An annular seat 126 is disposed at the top of the housing 7 and is fitted onto the filter basket 125. A groove 127 is arranged around the inner side wall of the annular seat 126. A slider 128 located in the groove 127 is disposed at the top of the outer wall of the filter basket 125.

[0023] The outer side of the pool body 1 is provided with a support base 13 for fixing the motor 4. The impurity removal mechanism 3 includes a perforated plate 31 arranged longitudinally at the top of the pool body 1. A sliding rod I32 is arranged transversely inside the pool body 1, passing through a sliding hole on the perforated plate 31. A protruding plate 33 is also provided at the top of the perforated plate 31. A screw hole is provided on the protruding plate 33 for screwing with a lead screw II34. One end of the lead screw II34 extends to the outer side of the pool body 1. The transmission mechanism 6 includes a pulley 61 arranged at the end of the lead screw II34 and on the output shaft of the motor 4. The upper and lower pulleys 61 are connected by a transmission belt 62.

[0024] like Figure 1 , 4 As shown, an installation pipe 14 is provided on one side of the top of the pool body 1, and drainage pipes 15 are evenly arranged at the bottom of the installation pipe 14 above the impurity removal mechanism 3. The circulation pipe 9 is connected to the installation pipe 14.

[0025] like Figure 4 As shown, the top of the strip seat 52 is provided with a boss 16, and the boss 16 is provided with a screw hole that is screwed to the lead screw I51. The pool body 1 is also provided with a slide rod II that passes through the slide hole on the boss 16.

[0026] In this embodiment, the bottom end of the strip plate 54 is attached to the bottom wall of the pool body 1, and through holes are evenly distributed on the side wall of the strip plate 54. When the strip plate 54 moves at the bottom of the pool body 1, the through holes facilitate the flow of liquid on both sides of the strip plate 54 and reduce the resistance caused by the liquid to the movement of the strip plate 54.

[0027] The working principle of this invention is as follows: Excrement and residual feed particles fall through the grid plate 2 into the bottom of the pool 1 and accumulate. At this time, the motor 4 drives the lead screw I51 to rotate in the screw hole in the boss 16, thereby driving the strip seat 52 to move left and right, and at the same time driving the corrugated hose 56 to contract and expand. Due to its own characteristics, the corrugated hose 56, after contraction and curling, will not affect the flow of liquid inside. While the strip seat 52 is moving, it will drive the sliding hole to slide on the slide rod II to prevent the strip seat 52 and the lead screw I51 from rotating together. Furthermore, as the strip seat 52 moves, it will drive the strip plate 54 to move at the bottom of the pool 1. The moving strip plate 54 will scrape off the impurities accumulated at the bottom of the pool 1 and mix them with the liquid. At the same time, the water pump II 10 works to extract the impurities scraped up by both sides of the strip plate 54 along with the liquid at the bottom of the pool through the connecting pipe 11, corrugated hose 56, cavity 53 and water suction hole 55. Thus, the cleaning mechanism 5, which moves left and right, scrapes off the impurities accumulated at the bottom of the pool 1 and extracts them, thereby improving the environment at the bottom of the pool 1.

[0028] After the water pump II10 extracts the impurities mixed with the liquid from the pool 1 through the connecting pipe 11 and the cleaning mechanism 5, it will guide this portion of the liquid into the cylinder 121 to push the push plate 123, thereby causing the round rod 122 to rotate. The rotating round rod 122 then drives the filter basket 125 to rotate. At this time, the liquid in the cylinder 121 will flow into the filter basket 125 through the recovery pipe 124. While the filter basket 125 filters the impurities in the liquid, the rotating filter basket 125 can generate centrifugal force between the impurities and the liquid inside, accelerating the flow of the liquid inside. While improving filtration efficiency, it can effectively prevent impurities from settling and clogging the side wall pores of the filter basket 125 during filtration, thus affecting the filtration process. During the above process, the rotating filter basket 125 will drive the slider 128 to slide in the slide groove 127. After a certain period of use, the switch door on the side wall of the box 7 can be opened to clean the impurities in the filter basket 125. The water pump I8 works to draw the filtered liquid at the bottom of the box 7 into the installation pipe 14 through the circulation pipe 9 and return it to the pool 1 through the outlet pipe 15, thereby achieving the purpose of water circulation in the pool 1.

[0029] When the motor 4 drives the cleaning mechanism 5 to work, the output shaft of the motor 4 will also drive the transmission belt 62 through the pulley 61 to drive the lead screw II 34 to rotate in the screw hole on the convex plate 33. At this time, the convex plate 33 drives the perforated plate 31 to move left and right in the pool body 1. The moving perforated plate 31 will drive the sliding hole on its side wall to slide on the slide rod I 32. The slide rod I 32 indirectly prevents the perforated plate 31 and the lead screw II 34 from rotating together. It should be noted that the perforated plate 31 moves below the drain pipe 15, and the liquid level in the pool body 1 is between the upper and lower ends of the perforated plate 31. The moving direction of the strip seat 52 and the perforated plate 31 is... In the same direction, when the strip seat 52 contacts the side wall of the pool body 1, there is also a gap between the perforated plate 31 and the corresponding side wall of the pool body 1. This gap facilitates the cleaning of the collected floating impurities. The present invention uses the moving perforated plate 31 to push the impurities floating on the top liquid level surface inside the pool body 1 to the top side inside the pool body 1 for easy cleaning. At the same time, the motor 4 drives the cleaning mechanism 5 to clean the impurities at the bottom of the pool body 1, and the motor 4 also drives the impurity removal mechanism 3 to collect the floating impurities at the top of the pool body 1 to the top two sides inside the pool body 1 for easy cleaning.

[0030] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
