Description

Technical Field

[0001] This invention relates to the field of abalone farming technology, specifically to an automatically flushable abalone seedling cultivation pond. Background Technology

[0002] In abalone farming, to improve production efficiency, abalone larvae are raised in artificial larval rearing ponds until they reach a certain size before being transferred to marine ranches. During the larval rearing process, the rearing ponds require daily routines of feeding, water changes, rinsing off leftover feed, washing away feces, and flushing away dead larvae. Simultaneously, to ensure water quality, the water in the rearing ponds needs to be circulated and refreshed. Furthermore, because abalone are nocturnal, shaded hatching beds must be placed in the rearing ponds. However, the presence of these hatching beds creates many unsanitary corners in the rearing ponds, hindering proper cleaning.

[0003] Chinese utility model patent CN205756533U discloses an abalone pond cleaner, which includes a siphon component, an inlet hose, a suction ball, and an outlet hose. The siphon component includes a nozzle and a handle, with the nozzle connected to the handle. The inlet hose is also connected to the handle, and the inlet hose, suction ball, and outlet hose are sequentially and integrally connected. It also includes a filter body with an inlet and an outlet. The inlet hose includes an inlet section and an outlet section, and the filter body is positioned between the inlet and outlet sections, with its inlet and outlet connected to the inlet and outlet sections, respectively. While this abalone pond cleaner can achieve the purpose of cleaning abalone ponds, its efficiency is clearly very low, and the cleaning is not thorough enough.

[0004] In summary, there is an urgent need to develop an automatically rinsing abalone larvae rearing pond that can not only clean the pond but also improve efficiency and cleaning effectiveness. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an abalone seedling cultivation pond that can be automatically rinsed. It has a built-in rinsing function and uses an automatic spray truck to rinse the cultivation pond. It has a high degree of automation, high cleaning efficiency and more thorough cleaning.

[0006] The technical solution of this invention is as follows:

[0007] An automatically flushable abalone larvae rearing pond includes a pond body with a water supply pipe at one end and a drainage pipe and overflow pipe at the other end. Solenoid valves are installed on the water supply and drainage pipes. An incubation bed is installed inside the pond. An automatic spraying vehicle is installed on the pond body, comprising a frame spanning both sides of the pond body's width. Drive wheels and driven wheels are respectively installed on both sides of the frame, positioned along the edge of the pond body. The drive wheels are driven by a motor. A water storage tank is installed on the frame, with a water inlet at the top. A water replenishment pipe is installed at one end of the pond body, supplying water to the storage tank. The storage tank is connected to a spraying pipe with several nozzles spaced apart.

[0008] Preferably, the incubation bed includes several curtain 1s spaced apart within the pool body, with curtain 2s on the same side of each curtain 1. Curtain 1 and curtain 2 have several through holes spaced apart at their lower parts, and their lengths extend along the length of the pool body. The bottoms of curtain 1 and curtain 2 are fixed to the bottom of the pool body, and the top of curtain 1 is lower than the top of curtain 2. A swing arm mechanism is provided at both ends of the pool body. The swing arm mechanism includes a bottom connecting rod located at the bottom of the pool body, with swing arm 1s hinged to both ends of the bottom connecting rod. The two swing arm 1s are connected to each other on the same side. A second swing arm is provided, which is hinged to the bottom connecting rod. The top of the first swing arm is lower than the top of the second swing arm. The tops of the two first swing arms are connected to the top connecting rod one, and the tops of the two second swing arms are connected to the top connecting rod two. The top of the first bed curtain is connected to the top connecting rod one at both ends via a support rod, and the top of the second bed curtain is connected to the top connecting rod two at both ends via a support rod. Swing arm connecting rods are respectively hinged to the first and second swing arms located on the same side at both ends of the pool. The two swing arm connecting rods are hinged to the upper and lower telescopic mechanism, which is set on the pool.

[0009] Preferably, the upper and lower telescopic mechanism adopts an electric push rod, and the telescopic rod of the electric push rod is hinged to the swing rod connecting rod.

[0010] Preferably, the pool body is provided with cross braces at both ends, and the electric push rod is fixed on the cross braces.

[0011] Preferably, the through hole is elongated.

[0012] Preferably, guide mechanisms are provided on both sides of the frame.

[0013] Preferably, the guiding mechanism includes a connecting plate fixed on the frame, and a guide wheel is connected to one end of the connecting plate near the pool body. The guide wheel contacts the outer wall of the pool body and rolls along the pool body under the drive of the drive wheel.

[0014] Preferably, limit switches are provided at both the front and rear ends of the frame.

[0015] Preferably, a water pump is installed on the spray pipeline.

[0016] Preferably, a solenoid valve is installed on the spray pipe.

[0036] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of this invention will be clearly and completely described below in conjunction with the embodiments of this invention.

[0037] Example 1

[0038] like Figure 1 As shown, this embodiment provides an automatically flushable abalone larvae rearing pond, including a pond body 1. One end of the pond body 1 is equipped with a water supply pipe 101, and the other end is equipped with a drain pipe 102 and an overflow pipe 103. Solenoid valves 6 are installed on the water supply pipe 101 and the drain pipe 102. Water is supplied to the rearing pond through the water supply pipe 101, and the water in the rearing pond is discharged through the drain pipe 102. The overflow pipe 103 allows water flowing into the rearing pond to overflow, maintaining a certain liquid level in the rearing pond. Simultaneously, to prevent abalone larvae from being discharged from the rearing pond with the water, mesh screens can be installed at the drain outlet of the drain pipe 102 and the overflow outlet of the overflow pipe 103.

[0039] To achieve automatic flushing of the cultivation tank, such as Figure 1-8 As shown, in this embodiment, an automatic spraying vehicle 3 is installed on the pool body 1. The automatic spraying vehicle 3 includes a frame 301 spanning both sides of the width direction of the pool body 1. A drive wheel 302 and a driven wheel 303 are respectively installed on both sides of the frame 301. The drive wheel 302 and the driven wheel 303 are positioned on the edge of the pool body 1. The drive wheel 302 is driven by a motor to rotate, thereby driving the automatic spraying vehicle 3 to move back and forth along the length direction of the cultivation pool to rinse the cultivation pool. The driven wheel 303 cooperates with the drive wheel 302 to support and balance the automatic spraying vehicle 3. In addition, two guide mechanisms 307 are respectively installed on both sides of the frame 301 to guide the movement of the automatic spraying vehicle 3, ensuring that the automatic spraying vehicle 3 travels in a straight line along the edge of the pool and does not deviate from the edge. Specifically, the guiding mechanism 307 includes a fixing block 3072, which is fixed to the frame 301. The fixing block 3072 has an insertion hole into which a connecting plate 3071 is inserted. The connecting plate 3071 has several bolt holes spaced along its length. The fixing block 3072 also has one bolt hole. The connecting plate 3071 is fixed to the fixing block 3072 by bolts 3073. A guide wheel 3074 is connected to one end of the connecting plate 3071 near the pool body 1. The guide wheel 3074 contacts the outer wall of the pool body 1 and rolls along the pool body 1 under the drive of the drive wheel 302. The distance between the guide wheel 3074 and the outer wall of the pool body 1 can be adjusted by adjusting the position of the bolt 3073 inserted into the bolt hole on the connecting plate 3071, thereby adjusting the pressure of the guide wheel 3074 against the outer wall of the pool body 1. A V-shaped plate 3075 is also provided at one end of the connecting plate 3071 near the pool body 1, which can serve as a guide when the automatic sprinkler cart 3 is initially pushed from one end of the pool body 1 onto the pool. At the same time, limit switches 308 can be provided at both the front and rear ends of the frame 301 to control the travel of the automatic sprinkler cart 3.

[0040] like Figure 1-2 As shown, a water storage tank 304 is installed on the frame 301, with a water inlet 3041 at the top. A water supply pipe 104 is installed at one end of the pool body 1, and a solenoid valve 6 is installed on the water supply pipe 104. The water supply pipe 104 and the water supply pipe 101 are located at the same end of the pool body 1. When the automatic sprinkler truck 3 stops at the end of the water supply pipe 104 of the pool body 1, the outlet of the water supply pipe 104 is located at the water inlet 3041 at the top of the water storage tank 304, and water is supplied to the water storage tank 304 through the water supply pipe 104, so that the water storage tank 304 stores and transports the water required for sprinkler operation. Figure 5 , 8As shown, the water storage tank 304 is connected to a spray pipe 305. The spray pipe 305 is equipped with a water pump 309 and a solenoid valve 6, and has several nozzles 306 spaced apart. When rinsing the cultivation tank, as the automatic spraying vehicle 3 moves above the cultivation tank, water from the water storage tank 304 is sprayed into the tank body 1 through the nozzles 306, thus completing the rinsing operation of the cultivation tank. Simultaneously, the water pump 309 increases the water pressure within the spray pipe 305, improving the spraying effect. Furthermore, as... Figure 2 As shown, a controller 4 and a power supply 5 are also provided on the frame 301. The controller 4 provides automated operation control and program management for the automatic sprinkler truck 3, while the power supply 5 provides power for the operation of the automatic sprinkler truck 3.

[0041] At the same time, because abalone have a nocturnal lifestyle, therefore... Figure 1 As shown, a shaded hatching bed 2 is provided inside the cultivation tank. Specifically, in this embodiment, as... Figure 9-11 As shown, the hatching bed 2 includes four parallel curtains 201 spaced apart within the tank 1. Four curtains 202 are also parallel to each other on the same side of the curtains 201. The curtains 201 and 202 are arranged at equal intervals. The lengths of the curtains 201 and 202 extend along the length of the tank 1, and their bottoms are fixed to the bottom of the tank 1. The lower parts of the curtains 201 and 202 are provided with several elongated through holes 203, providing passageways for abalone to pass through the curtains 201 and 202 in the hatching bed 2. Figure 10 , 12 As shown, the top of curtain 1 201 is lower than the top of curtain 2 202 to create the effect of a short curtain and a long curtain. Both curtain 1 201 and curtain 2 202 are made of fiber fabric with light-blocking and elastic properties, providing conditions for the formation of shaded area 7.

[0042] like Figure 9-13As shown, a swing arm mechanism 204 is provided at both ends of the pool body 1. The swing arm mechanism 204 includes a bottom connecting rod 2041 provided at the bottom of the pool body 1. A swing arm 2042 is hinged to both ends of the bottom connecting rod 2041. A swing arm 2043 is provided on the same side of the two swing arms 2042. The swing arm 2043 is hinged to the bottom connecting rod 2041. Adjacent swing arms 2042 and swing arms 2043 form a group, and each group is located on both sides of the bottom connecting rod 2041. The top of swing arm 1 2042 is lower than the top of swing arm 2043 to create the effect of a short swing arm and a long swing arm. The tops of the two swing arms 1 2042 are connected to the top connecting rod 1 2044, and the tops of the two swing arms 2043 are connected to the top connecting rod 2045. The top of curtain 1 201 is connected to the top connecting rod 1 2044 at both ends via support rod 205, and the top of curtain 2 202 is connected to the top connecting rod 2045 at both ends via support rod 205. The support rod 205 supports curtain 1 201 and curtain 2 202, making them taut. Meanwhile, at both ends of the pool body 1, at one of the sets of swing rods 2042 and 2043, there are vertical telescopic mechanisms respectively. In this embodiment, the vertical telescopic mechanism can be an electric push rod 206. The top of the electric push rod 206 is fixed on the cross brace 105 at both ends of the pool body 1. Its telescopic rod faces downward and is hinged to two symmetrically arranged swing rod connecting rods 2046. The two swing rod connecting rods 2046 are respectively hinged to swing rod 2042 and swing rod 2043.

[0043] Therefore, the parallel swing rods 2042 and 2043 will swing synchronously left and right under the extension and retraction of the electric push rod 206, and the bed curtain 201 will swing synchronously left and right with the swing rod 2042, while the bed curtain 202 will swing synchronously left and right with the swing rod 2043. Figure 14 As shown, when the telescopic rod of the electric push rod 206 extends, its hinge point with the swing rod connecting rod 2046 moves downward. The tops of the swing rod 1 2042 and swing rod 2043 at the electric push rod 206 converge, thereby causing the curtains 1 201 and 202 connected to the top connecting rod 1 2044 and top connecting rod 2045 to move closer together. This causes the higher curtain 202 to cover the lower curtain 1 201, thus forming a triangular shading area 7. The other curtains 1 201 and 202 simultaneously form triangular shading areas 7, and an open area 8 is formed between the shading areas 7. Conversely, as... Figure 15As shown, when the telescopic rod of the electric push rod 206 retracts, the hinge point between it and the swing rod connecting rod 2046 moves upward, and the tops of the swing rod 1 2042 and swing rod 2043 at the electric push rod 206 move away from each other. This causes the curtains 1 201 and curtain 2 202 connected to the top connecting rod 1 2044 and top connecting rod 2045 to move away from each other, thus turning the original shaded area 7 into an open area 8, and the original open area 8 into a shaded area 7. As the shaded area 7 of the incubation bed 2 changes, the different open areas 8 of the incubation bed 2 can be rinsed separately by the automatic spray truck 3, avoiding the problem of dead corners in the rinsing process of the cultivation tank, and making the cleaning more thorough.

[0044] Working principle:

[0045] S1 Abalone Seedling Culture Pond Water Circulation: During the abalone seedling culture pond operation, the solenoid valve 6 of the drainage pipe 102 at one end of the culture pond is closed to stop drainage, and the solenoid valve 6 of the water supply pipe 101 of the culture pond is opened to continuously supply clean water with set water quality parameters such as water volume, temperature, and pH to the culture pond 1. Excess water in the pond 1 is discharged through the overflow port of the overflow pipe 103 located at the opposite end of the water supply pipe 101 of the culture pond, thereby ensuring that the water in the pond 1 is continuously circulated and renewed, maintaining stable water quality and the liquid level is level with the overflow port.

[0046] S2 Rinsing Preparation: After the abalone larvae have been fed at night for 4 hours (during which time the larvae complete their nighttime feeding and defecation), the abalone larvae rearing pond 1 and hatching bed 2 are rinsed to remove residual feed, feces, dead larvae, and other impurities to ensure water quality. During rinsing, the solenoid valve 6 of the water supply pipe 101 is closed to stop the water supply to pond 1, and the solenoid valve 6 of the drain pipe 102 is opened to drain the water from pond 1. At this time, the automatic spray truck 3 moves to one end of the water replenishment pipe 104 of the rearing pond. The outlet of the water replenishment pipe 104 is located at the inlet 3041 at the top of the water storage tank 304. The water replenishment pipe 104 is opened to replenish the water storage tank 304. The opening time of the solenoid valve 6 can be set to ensure that the water replenishment volume can meet the water demand of the automatic spray truck 3 for two round trips during this time. At this time, the electric push rod 206 of the incubation bed 2 is in the extended state. The swing rod 1 2042 and swing rod 2043 at the electric push rod 206 move closer to each other and drive the corresponding bed curtain 1 201 and bed curtain 2 202 to move closer to each other, forming a shaded area 7 for abalone to attach and hide.

[0047] S3 First Rinse: After replenishing water, the automatic spray truck 3 opens the solenoid valve 6 on the water pump 309 and the spray pipe 305 to spray and rinse the inside of the cultivation tank 1 and the sunny side of the hatching bed 2. It then slowly moves along the length of the cultivation tank 1 until the limit switch 308 at the front end of the automatic spray truck 3 touches the cross brace 105 at the end of the cultivation tank, sending a feedback signal to the controller 4. The controller 4 then closes the solenoid valve 6 on the water pump 309 and the spray pipe 305, stopping the spraying onto the tank 1. The automatic spray truck 3 then returns to its initial position.

[0048] S4 Second Rinse: The electric push rod 206 of the incubation bed 2 changes to the retracted state. The swing rod 1 2042 and swing rod 2043 at the electric push rod 206 move away from each other, causing the corresponding curtain 1 201 and curtain 2 202 to move away from each other and move closer together with curtain 1 201 or curtain 2 202 on the other side to form a new shaded area 7. At this time, the original shaded area 7 becomes an open area 8, the original open area 8 becomes a new shaded area 7, and the original shaded side of the curtain becomes the sunny side. At this time, the automatic spray truck 3 turns on the water pump 309 and the solenoid valve 6 on the spray pipe 305 to spray and rinse the inner side of the cultivation tank 1 and the sunny side of the incubation bed 2. It then slowly moves along the length of the cultivation tank 1 until the limit switch 308 at the front end of the automatic spray truck 3 touches the cross brace 105 at the end of the cultivation tank, sending a feedback signal to the controller 4. The controller 4 then turns off the water pump 309 and stops spraying the tank 1. The automatic spray truck 3 returns to its initial position and waits for a set time (after which the water in the water storage tank 304 is completely emptied) before turning off the solenoid valve 6 on the spray pipe 305, completing the entire spraying and rinsing process.

[0049] S5 Incubation Pool Water Replenishment: Close the solenoid valve 6 of the drainage pipe 102 and open the solenoid valve 6 of the water supply pipe 101 to replenish and circulate water in the incubation pool.
