Description

Technical Field

[0001] The present application relates to the technical field of aquaculture ponds, and in particular to aquaculture ponds with a slag retaining device. Background Art

[0002] Before they grow up, fry are usually placed in aquaculture ponds for cultivation. Activities such as feed addition, biological excretion and plankton formation will cause scum to float on the surface of the aquaculture pond.

[0003] Existing methods for cleaning scum are usually to scoop it up with a net bag. However, in order to increase the dissolved oxygen content in the water, an inlet pipe and an outlet pipe are usually installed in the aquaculture pond to circulate the water in the aquaculture pond. When the operator uses a net bag to scoop up the scum, the flowing water can easily displace the scum, making it more difficult to clean the scum. Summary of the Invention

[0004] In order to improve the convenience of cleaning scum in aquaculture ponds, the present application provides aquaculture pond with a scum blocking device.

[0005] The present application provides a breeding pond with a slag blocking device, which adopts the following technical solution:

[0007] By adopting the above technical solution, when the water in the pool forms a circular flow, the water flows through the debris barrier, and the floating debris in the water flow is intercepted by the debris barrier. When the water in the pool body overflows, the water flows through the filter element and enters the overflow chamber, and then flows out of the debris barrier from the overflow chamber. This allows water to flow into the water inlet pipe while the debris barrier drains water, thereby circulating the water in the pool body and preventing it from overflowing from the top surface of the pool body. The floating debris is easily accumulated on one side of the debris barrier for easy cleaning. The filter element also prevents the cultured organisms in the pool body from entering and being discharged from the debris barrier.

[0014] The top of the mounting tube is provided with a mounting portion, and each of the salvaged pieces is provided with a locking piece, and the locking piece is used to lock with the mounting portion;

[0015] The salvage pieces have a static state and a use state; when the salvage pieces are in the static state, each of the salvage pieces is locked with the connection plate, and the salvage piece located on the upper side of the inlet is locked with the mounting portion by the locking piece;

[0016] When the salvage piece is in use, the salvage piece located at the lower side of the inlet is unlocked from the connecting disk, and then the salvage piece at the lower side of the inlet is moved to abut against the salvage piece located at the upper side of the inlet and re-locked with the connecting disk, so that the salvaged scum is enclosed in the accommodating cavity abutting against the salvage piece, and the inlet is reformed; thereafter, the lock of the mounting portion is unlocked, so that the support cylinder and the filter cylinder can be rotated to lock the mounting portion with the salvage piece on the upper side of the reformed inlet.

[0017] By adopting the above technical solution, the movement of the salvage piece drives the scum to be collected in the accommodating chamber of the salvage piece, and the change in position of the salvage piece drives the change in position of the support tube and the filter tube.

[0041] The following is combined with Figure 1-8 This application is described in further detail.

[0042] Example 1:

[0043] The embodiment of the present application discloses a breeding pond with a slag blocking device. Figure 1 The aquaculture pond with a slag blocking device includes a pond body 1, a water inlet pipe 2 and a slag blocking member.

[0044] The pool body 1 is circular and has an upward-facing opening. A vertically extending, tubular guide rod 21 is fixed to the center of the pool body 1. A water inlet pipe 2 is fixedly mounted on the outer wall of the pool body 1. One end of the water inlet pipe 2 enters the pool body 1 through the top opening and faces the inner wall of the pool body 1. The opposite end of the water inlet pipe 2 is located outside the pool body 1 and connected to a water source (not shown). The water source continuously supplies water to the water inlet pipe 2, causing the water in the water inlet pipe 2 to continuously spray water at an angle toward the inner wall of the pool body 1, forming a circular flow in the pool body 1 that circulates around the guide rod 21.

[0045] The slag retaining member is provided through the pool wall on one side of the pool body 1. The portion of the slag retaining member located inside the pool body 1 is located on the water surface of the pool body 1 and is equipped with a filter element. The slag retaining member is also located in the path of the circulating flow. An overflow chamber 3 is formed inside the slag retaining member. One end of the slag retaining member located outside the pool body 1 connects the external environment with the overflow chamber 3. When the circulating flow reaches the slag retaining member, the slag is filtered by the filter element and then enters the overflow chamber 3 of the slag retaining member. The slag is then discharged into the external environment, i.e., out of the pool body 1, through the overflow chamber 3. The water inflow of the water inlet pipe 2 and the water outflow of the slag retaining member form a balance, so that the water flow in the pool body 1 is not easy to overflow the pool body 1, and the floating slag on the water surface of the pool body 1 is intercepted on the side of the slag retaining member for the circulating flow to flow in.

[0046] Reference Figure 1 and Figure 2 Specifically, the slag blocking member in the embodiment of the present application includes a slag blocking pipe 4, which is in the shape of a circular tube, and the overflow chamber 3 is the hollow part of the slag blocking pipe 4. The slag blocking pipe 4 is fixedly penetrated on the wall of the pool body 1 along the radial direction of the pool body 1, and the axial direction of the slag blocking pipe 4 coincides with the radial direction of the pool body 1, and the slag blocking pipe 4 is close to the water inlet pipe 2. The slag blocking pipe 4 is located at one end inside the pool body 1, which is closed and close to the guide rod 21, and the slag blocking pipe 4 is located at one end outside the pool body 1, and a connecting port 5 is provided on the peripheral wall of the slag blocking pipe 4 close to the guide rod 21. The connecting port 5 is located on the side of the slag blocking pipe 4 relative to the entrance of the circulating flow, that is, the connecting port 5 is located on the side of the slag blocking pipe 4 away from the water inlet pipe 2.

[0047] The filter element in this embodiment includes a filter screen 6, which is a grid-shaped arc sheet. The aperture of the holes formed by the filter screen 6 is smaller than the size of the fry in the pool body 1, and the filter screen 6 covers the connecting port 5 of the slag pipe 4, so that the water flow and the slag with a particle size smaller than the aperture of the filter screen 6 can pass through the filter screen 6 into the overflow chamber 3 of the slag pipe 4, and the water flow and slag flowing into the overflow chamber 3 are discharged from the pool body 1 from the overflow pipe, while the slag with a particle size larger than the aperture of the filter screen 6 is intercepted outside the filter screen 6. The operator can salvage the slag accumulated on the side of the slag pipe 4 on the filter screen 6 from the side of the slag pipe 4 facing the circulation entry direction.

[0048] The operating principle of the aquaculture pond with a debris-retaining device according to the embodiment of the present application is as follows: the water inlet pipe 2 continuously sprays water at an angle toward the inner wall of the pond body 1, causing the water in the pond body 1 to circulate circumferentially around the pond body 1, forming a circular flow. The circular flow carries scum on the water surface toward the scum-retaining pipe 4, where it is intercepted by the scum-retaining pipe 4 and the filter screen 6. The water then flows through the filter screen 6 into the scum-retaining pipe 4 and is discharged from the pond body 1 through the scum-retaining pipe 4.

[0049] Example 2:

[0050] The difference between the embodiment of the present application and the first embodiment lies in the difference in the slag retaining element and the filter element.

[0051] The embodiment of the present application discloses a breeding pond with a slag blocking device. Figure 3 and Figure 4 The slag blocking member includes a support tube 7, which is a cylindrical shape with two opposite ends passing through. The support tube 7 is radially penetrated on the wall of the pool body 1, and the axial direction of the support tube 7 coincides with the radial direction of the pool body 1. The two ends of the support tube 7 that are far away from each other are respectively located on the inner and outer sides of the pool body 1, and the overflow chamber 3 is the hollow part of the support tube 7.

[0052] The filter element includes a filter cartridge 8, which is cylindrical with one end open. Made of a hard mesh, the filter cartridge 8 has a pore size smaller than the size of the fry in the tank 1. The outer diameter of the filter cartridge 8 matches that of the support cartridge 7. The end of the filter cartridge 8 with one open end is coaxially fixed to the end of the support cartridge 7 located within the tank 1, ensuring communication between the filter cartridge 8 and the support cartridge 7. The end of the filter cartridge 8 facing away from the support cartridge 7 is adjacent to the guide rod 21. When circulating air flows within the tank 1, scum is intercepted on the side of the filter cartridge 8 and support cartridge 7 facing the incoming flow.

[0053] Reference Figure 5 and Figure 6 Furthermore, a salvage piece 9 for salvaging scum is abutted against the outer walls of the filter barrel 8 and the support barrel 7. Multiple salvage pieces 9 are distributed along the circumference of the support barrel 7, and the multiple salvage pieces 9 are abutted in sequence along the circumference of the support barrel 7. In this embodiment, there are ten salvage pieces 9, which are abutted in sequence. Each salvage piece 9 extends at an angle of 30° along the circumference of the support barrel 7. The gap between two salvage pieces 9 located on the edges of the ten salvage pieces 9 forms an inlet 13. Water can flow through the inlet 13 to reach the filter barrel 8 and be filtered by the filter barrel 8. The inlet 13 is located on the side of the filter barrel 8 facing the direction of the circulating flow. The salvage piece 9 can slide along the circumference of the filter barrel 8 and the support barrel 7 to salvage scum accumulated at the inlet 13.

[0054] Reference Figure 3 and Figure 6 Specifically, a connecting disk 10 is coaxially fixed to the end of the filter cylinder 8 away from the support cylinder 7. The connecting disk 10 is disc-shaped, and the outer diameter of the connecting disk 10 is larger than the outer diameter of the filter cylinder 8. A mounting cylinder 11 is coaxially rotatably sleeved on the outer wall of the end of the support cylinder 7 away from the filter cylinder 8. The mounting cylinder 11 is cylindrical, and the outer wall of the mounting cylinder 11 is fixedly penetrated on the pool wall of the pool body 1, and the inner diameter of the mounting cylinder 11 is consistent with the outer diameter of the support cylinder 7. The outer diameter of the mounting cylinder 11 is larger than the outer diameter of the support cylinder 7 and smaller than the outer diameter of the connecting disk 10. Figure 7In order to ensure the stable rotation of the support cylinder 7, a mounting cylinder 11 is extended from one end of the support cylinder 7 away from the filter cylinder 8, and a mounting seat 22 is detachably mounted on the outer wall of the pool body 1 by bolts. The mounting seat 22 is mounted on the outer wall of the support cylinder 7 extending from the mounting cylinder 11 through a bearing sleeve, so that the support cylinder 7 can rotate on the mounting seat 22.

[0055] Reference Figure 6 The two ends of each salvage piece 9, facing away from each other, respectively abut against the surface of the connecting disc 10 that faces the mounting tube 11. Each salvage piece 9 is provided with a positioning member 15 that cooperates with the connecting disc 10. The positioning member 15 allows the salvage piece 9 to be positioned relative to the connecting disc 10. When the salvage piece 9 is released from its position relative to the connecting disc 10, it can move circumferentially along the filter tube 8. Each salvage piece 9 is also provided with a locking member 17. A mounting portion 16 is formed at the top of the mounting tube 11. When the salvage piece 9 located above the inlet 13 is locked with the connecting disc 10, it can be locked with the mounting portion 16 via the locking member 17, thereby locking the salvage piece 9, the support tube 7, the connecting disc 10, and the mounting tube 11 relative to each other.

[0056] Reference Figure 5 and Figure 6 Each salvage piece 9 is formed with a receiving cavity 14 opening toward the adjacent salvage piece 9. The receiving cavity 14 of the salvage piece 9 adjacent to and above the inlet 13 is in communication with the inlet 13, while the openings of the receiving cavities 14 of the remaining salvage pieces 9 are closed by the adjacent salvage pieces 9. A drain outlet 12 is formed at the bottom of the mounting tube 11, extending through the mounting tube 11 and away from both ends. The drain outlet 12 extends through the inner side of the mounting tube 11 where it contacts the support tube 7, and extends at a 60° angle along the circumference of the mounting tube 11.

[0057] Reference Figure 3 and Figure 6 The salvage piece 9 has a static state and a use state. When the salvage piece 9 is in the static state, all the salvage pieces 9 are locked on the connecting plate 10. The inlet 13 is formed between the middle and top of the support cylinder 7 and the filter cylinder 8. The salvage piece 9 adjacent to the inlet 13 and located on the upper side of the inlet 13 is locked with the mounting cylinder 11. The upper surface of the salvage piece 9 adjacent to the inlet 13 and located on the lower side of the inlet 13 is in a horizontal state extending in the horizontal direction. At this time, the sewage outlet 12 is in contact with the support cylinder 7. The accommodating chambers 14 of the two salvaging pieces 9 at the bottom of the filter cartridge 8 are connected, so that after the circulating flow enters the filter cartridge 8 from the inlet 13, part of the water flow will enter the accommodating chamber 14 of the salvaging piece 9 at the bottom of the filter cartridge 8 through the pores at the bottom of the filter cartridge 8, and flow into the sewage outlet 12 through the accommodating chamber 14 and flow out of the pool body 1 from the sewage outlet 12, and at the same time bring the scum accumulated in the accommodating chamber 14 out of the pool body 1, and part of the water flow will pass through the filter cartridge 8 into the overflow chamber 3 of the support cylinder 7 and flow out of the pool body 1 from the overflow chamber 3.

[0058] When the salvage piece 9 is in use, the salvage piece 9 adjacent to the inlet 13 and located below the inlet 13 is first unlocked from the connecting plate 10, and then the unlocked salvage piece 9 is moved upward along the circumference of the filter cartridge 8 until it abuts against the salvage piece 9 located above the original inlet 13 and is locked with the connecting plate 10. The moved salvage piece 9 brings the scum accumulated at the inlet 13 upward into the accommodating cavity 14 of the adjacent salvage piece 9 for collection, and the accommodating cavity 14 of the adjacent salvage piece 9 is closed, so that the two salvage pieces 9 located on both sides of all the salvage pieces 9 are replaced, so that a new inlet 13 is formed. Afterwards, the lock between the salvage piece 9 located on the upper side of the original inlet 13 and the installation cylinder 11 is released, and then the support cylinder 7, the filter cylinder 8, the salvage piece 9 and the connecting plate 10 are rotated upward 30° as a whole, so that the salvage piece 9 located on the upper side of the new inlet 13 is opposite to the top of the installation cylinder 11, and then the salvage piece 9 located on the upper side of the new inlet 13 is locked with the installation cylinder 11, so that the salvage piece 9 returns to a stationary state.

[0059] Reference Figure 6 and Figure 8 Each salvage element 9 includes a first baffle 91 and a second baffle 92 connected to each other. The first baffle 91 includes an outer frame 911 and a filter gauze 912. The outer frame 911 is in the shape of a hollow square. The filter gauze 912 is fixed to the hollow portion of the outer frame 911. The pore size of the filter gauze 912 is smaller than that of the filter cylinder 8, which can block debris and allow water to flow through. One side of the outer frame 911 abuts against the outer wall of the filter cylinder 8 and the support cylinder 7. The surface of the outer frame 911 extends along the radial extension of the support cylinder 7, and the two ends of the outer frame 911 that are far away from each other abut against the adjacent sides of the connecting plate 10 and the mounting cylinder 11. A circular limiting ring 23 is coaxially fixed on the outer wall of the support tube 7. The end of the longitudinal section of the limiting ring 23 is in a dovetail shape with the width gradually decreasing towards the support tube 7. A limiting groove 24 is provided on the side wall of the outer frame 911 and is slidably sleeved on the outer wall of the limiting ring 23 to guide the movement of the outer frame 911 along the axial direction of the support tube 7 and limit the outer frame 911 from radially leaving the support tube 7 and the filter tube 8 along the support tube 7.

[0060] The second baffle 92 is an arc-shaped plate made of a hard, water-resistant material. One side of the second baffle 92 is fixed to the side of the outer frame 911 of the first baffle 91, away from the outer wall of the support tube 7. The second baffle 92 is coaxially arranged with the support tube 7. The two ends of the second baffle 92, which are spaced apart from each other along its length, respectively abut the adjacent surfaces of the connecting plate 10 and the mounting tube 11. The first baffle 91 and the second baffle 92 form an L-shaped structure, and the central angle corresponding to the arc surface of the second baffle 92 is 30°. The accommodating cavity 14 is formed in the space enclosed by the first baffle 91 and the second baffle 92.

[0061] Reference Figure 6 and Figure 8A sliding base 18 is fixed to the side of each second baffle 92 facing away from the support tube 7. The positioning member 15 includes a sliding rod 151 that is slidably inserted into the sliding base 18. The sliding rod 151 corresponds to the second baffle 92 one by one. The sliding rod 151 is in the shape of a round rod, and the sliding rod 151 is inserted into the sliding base 18 in a direction parallel to the axis of the support tube 7. Twelve positioning grooves 19 are evenly spaced along the circumference of the connecting disk 10 on the side facing the mounting tube 11. The positioning grooves 19 are used for inserting the sliding rod 151 when it moves toward the connecting disk 10, so that the second baffle 92 and the connecting disk 10 are relatively positioned. Magnets that can attract each other are embedded in the inner wall of the positioning groove 19 and the end of the sliding rod 151 near the connecting disk 10, so as to improve the stability of the sliding rod 151 when it is inserted into the positioning groove 19. In addition, in order to improve the stability of the sliding rod 151 during movement, a travel block (not shown in the figure) is fixed to the outer wall of the sliding rod 151, and a travel groove (not shown in the figure) is provided on the inner wall of the sliding base 18 for the travel block to slide axially parallel to the support tube 7, so as to limit the rotation of the sliding rod 151 in the sliding base 18.

[0062] Reference Figure 6 and Figure 8 The end of the sliding rod 151 away from the connecting disk 10 is opposite to the outer wall of the mounting tube 11 and is located in the tank body 1. The locking member 17 corresponds to the sliding rod 151 one by one and is arranged at the position opposite to the mounting tube 11. The locking member 17 includes an inserting rod 171, a handle 172 and an elastic portion 173. The inserting rod 171 is in the shape of a round rod and is radially slidably inserted into the sliding rod 151 along the mounting tube 11. The handle 172 is fixed to the end of the inserting rod 171 away from the mounting tube 11. The elastic portion 173 is a spring. The spring is sleeved on the outer wall of the sliding rod 151, and one end of the spring is fixedly connected to the handle 172, and the other end of the spring is fixedly connected to the side of the sliding rod 151 away from the mounting tube 11. The elastic force of the spring gives the handle 172 a tendency to move toward the mounting tube 11.

[0063] The mounting portion 16 is located on the top wall of the mounting tube 11. The mounting tube 11 has a slot 20 formed therein. The slot 20 is for the insertion rod 171 on the sliding rod 151 that moves relative to the mounting portion 16. When the sliding rod 151 is inserted into the positioning groove 19 and faces the mounting portion 16, the insertion rod 171 faces the slot 20. The elastic force of the spring drives the insertion rod 171 downward until it is inserted into the slot 20, thereby positioning the insertion rod 171 relative to the mounting tube 11. When the insertion rod 171 is inserted into the slot 20, the spring is in a stretched state. To release the lock between the insertion rod 171 and the mounting tube 11, pull the handle 172 upward until the insertion rod 171 is disengaged from the slot 20, thereby releasing the lock between the insertion rod 171 and the mounting tube 11, so that the filter tube 8 and the support tube 7 can rotate relative to the mounting tube 11.

[0064] The operating principle of the aquaculture pond with a slag interception device according to the embodiment of the present application is as follows: the circulating flow in the pond body 1 flows through the inlet 13 to the filter cartridge 8. The water flowing to the filter cartridge 8 flows through the pores of the filter cartridge 8 to the accommodating chamber 14 connected to the sewage outlet 12, or flows into the support tube 7 to overflow the pond body 1, and the scum is accumulated on one side of the filter cartridge 8 and the support tube 7. To clean the accumulated scum, the fishing piece 9 located below the inlet 13 is moved to the upper side of the inlet 13 so that the scum is stored in the accommodating chamber 14, and the filter cartridge 8 and the support tube 7 are rotated upward by 30 degrees. When the accommodating chamber 14 storing the scum is connected to the sewage outlet 12, the water flowing from the filter cartridge 8 into the accommodating chamber 14 carries the scum out of the pond body 1 through the sewage outlet 12.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
