Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and relates to a sewage discharge pipe suitable for industrial aquaculture ponds. Background Art

[0002] During the process of aquaculture, maintaining the cleanliness of the pond water is an important factor affecting the yield of aquatic organisms. In order to ensure the cleanliness of the aquaculture pond water, it is necessary to timely discharge the pollutants generated by factors such as the excretion of aquatic organisms, feed feeding, and the reproduction of algae in the water body in the aquaculture pond. In the existing aquaculture technology, a sewage discharge pipe is usually arranged in the aquaculture pond, and the water body containing oily pollutants in the aquaculture pond is timely discharged through the sewage discharge pipe. However, the existing sewage discharge pipes for aquaculture ponds can usually only discharge sewage from the upper layer of the water body, that is, only discharge the floating pollutants floating on the upper layer and the surface of the water body from the aquaculture pond. However, it is difficult to timely discharge the pollutants deposited in the lower layer of the water body in the aquaculture pond. Especially the feces of aquatic organisms and feed sediments deposited in the lower layer of the water body are difficult to be timely discharged through the existing sewage discharge pipes for aquaculture ponds, thereby affecting the cleanliness of the water body in the aquaculture pond.

[0003] Therefore, aiming at the problem that the existing sewage discharge pipes for aquaculture ponds cannot discharge the pollutants in the upper and lower layers of the water body at the same time, the utility model discloses a sewage discharge pipe suitable for industrial aquaculture ponds. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sewage discharge pipe suitable for industrial aquaculture ponds, which can discharge the upper and lower layers of the water body in the aquaculture pond respectively according to the sewage discharge requirements, thereby effectively discharging the upper and lower pollutants in the aquaculture pond in time and ensuring the cleanliness of the water body in the aquaculture pond.

[0005] The utility model is realized through the following technical solutions:

[0006] A sewage discharge pipe suitable for industrial aquaculture ponds includes an outer pipe body and an inner pipe body. A top sewage discharge port is arranged on the top side wall of the outer pipe body, and a bottom sewage discharge port is arranged on the bottom side wall of the outer pipe body. The inner pipe body is coaxially and slidably arranged inside the outer pipe body. A top flexible plug and a top inner port are sequentially arranged on the top outer wall of the inner pipe body corresponding to the top sewage discharge port. A bottom flexible plug and a bottom inner port are sequentially arranged on the bottom outer wall of the inner pipe body corresponding to the bottom sewage discharge port. The top end of the outer pipe body is closed and provided with a driving device for driving the inner pipe body to axially slide; the top flexible plug moves along with the inner pipe body to close the top sewage discharge port while enabling the bottom inner port to communicate with the bottom sewage discharge port; the bottom flexible plug moves along with the inner pipe body to close the bottom sewage discharge port while enabling the top inner port to communicate with the top sewage discharge port.

[0007] The sewage discharge pipe is inserted into the breeding pond. The inner pipe body is driven axially inside the outer pipe body by a driving device, so that the top flexible plug opens the top sewage discharge port at the top of the outer pipe body. At this time, the top inner port is communicated with the top sewage discharge port. At the same time, the bottom flexible plug blocks and closes the bottom sewage discharge port at the bottom of the outer pipe body, so that the water in the upper layer of the breeding pond enters the inner pipe body through the top sewage discharge port, and then the water in the upper layer of the breeding pond is discharged through the inner pipe body. At the same time, since the bottom sewage discharge port is closed, the water in the lower layer of the breeding pond cannot be discharged through the inner pipe body. By driving the inner pipe body to axially move inside the outer pipe body, the top flexible plug closes the top sewage discharge port at the top of the outer pipe body, and at the same time, the bottom flexible plug opens the bottom sewage discharge port at the bottom of the outer pipe body. At this time, the bottom inner port is communicated with the bottom sewage discharge port, so that the water in the lower layer of the breeding pond enters the inner pipe body through the bottom sewage discharge port, and then the water in the lower layer of the breeding pond is discharged through the inner pipe body. At the same time, since the top sewage discharge port is closed, the water in the upper layer of the breeding pond cannot be discharged through the inner pipe body.

[0008] In order to better implement the present utility model, further, the top sewage discharge port is located below the water surface. A cavity is reserved between the top end and the top sewage discharge port inside the outer pipe body. An air inlet pipe and an exhaust pipe are arranged on the side wall of the cavity.

[0009] In order to better implement the present utility model, further, the air inlet pipe is connected to an air inlet pump, and the exhaust pipe is connected to an exhaust pump.

[0010] In order to better implement the present utility model, further, at least one group of pressure membranes is arranged at the top of the cavity.

[0011] In order to better implement the present utility model, further, the driving device includes a connecting chuck and a driving cylinder. The connecting chuck is clamped to the top end of the inner pipe body. The driving cylinder is arranged at the top end of the outer pipe body. The cylinder rod of the driving cylinder is connected to the top of the connecting chuck.

[0012] In order to better implement the present utility model, further, axial guide strips are arranged on the outer wall of the inner pipe body. Guide grooves are arranged on the inner wall of the outer pipe body between the top sewage discharge port and the bottom sewage discharge port. The guide strips are slidably connected with the guide grooves.

[0013] In order to better implement the present utility model, further, a top funnel is arranged on the outer side of the top of the outer pipe body corresponding to the position of the top sewage discharge port, and a bottom funnel is arranged on the outer side of the bottom of the outer pipe body corresponding to the position of the bottom sewage discharge port.

[0014] In order to better implement the present utility model, further, spiral grooves are arranged on the inner walls of both the top funnel and the bottom funnel.

[0015] To better implement the present utility model, further, a filter structure is provided in the top sewage outlet and the bottom sewage outlet.

[0016] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0017] In the present utility model, a top sewage outlet and a bottom sewage outlet are respectively arranged on the outer side of the top and the outer side of the bottom of the outer pipe body, and an inner pipe body is axially slidably arranged inside the outer pipe body. The inner pipe body is driven by a driving device to axially slide, so that the top flexible plug on the outer side of the top of the inner pipe body closes the top sewage outlet while ensuring that the bottom sewage outlet communicates with the bottom inner opening on the outer wall of the bottom of the inner pipe body, thereby realizing the rapid discharge of the lower-layer water body of the aquaculture pond; by driving the inner pipe body to axially slide through the driving device, the bottom flexible plug on the outer side of the bottom of the inner pipe body closes the bottom sewage outlet while ensuring that the top sewage outlet communicates with the top inner opening on the outer wall of the top of the inner pipe body, thereby realizing the rapid discharge of the upper-layer water body of the aquaculture pond; finally, according to different sewage discharge requirements, the upper-layer water body and the lower-layer water body of the aquaculture pond can be discharged flexibly and efficiently, thereby being able to clean the floating-type pollutants and sediment-type pollutants in the aquaculture pond, and finally ensuring the cleanliness of the water body in the aquaculture pond.

[0033] Embodiment 1:

[0034] A sewage pipe applicable to an industrialized aquaculture pond in this embodiment, such as Figure 1 , Figure 2 , Figure 10As shown, it includes an outer tube body 1 and an inner tube body 2. A top sewage discharge port 3 is provided on the top side wall of the outer tube body 1, and a bottom sewage discharge port 4 is provided on the bottom side wall of the outer tube body 1. The inner tube body 2 is coaxially and slidably arranged inside the outer tube body 1. A top flexible plug 5 and a top inner port 6 are sequentially arranged on the top outer wall of the inner tube body 2 corresponding to the top sewage discharge port 3. A bottom flexible plug 7 and a bottom inner port 8 are sequentially arranged on the bottom outer wall of the inner tube body 2 corresponding to the bottom sewage discharge port 4. The top end of the outer tube body 1 is closed and is provided with a driving device 9 for driving the inner tube body 2 to axially slide; the top flexible plug 5 moves along with the inner tube body 2 to close the top sewage discharge port 3 while making the bottom inner port 8 communicate with the bottom sewage discharge port 4; the bottom flexible plug 7 moves along with the inner tube body 2 to close the bottom sewage discharge port 4 while making the top inner port 6 communicate with the top sewage discharge port 3.

[0035] As Figure 4 shown, three top sewage discharge ports 3 are evenly arranged along the circumferential direction on the outside of the top of the outer tube body 1, and three bottom sewage discharge ports 4 are evenly arranged along the circumferential direction on the outside of the bottom of the outer tube body 1. As Figure 5 shown, three groups of top flexible plugs 5 are arranged along the circumferential direction on the outside of the top of the inner tube body 2, and three top inner ports 6 are arranged along the circumferential direction below the three groups of top flexible plugs 5. Three groups of bottom flexible plugs 7 are arranged along the circumferential direction on the outside of the bottom of the inner tube body 2, and three bottom inner ports 8 are arranged along the circumferential direction above the three groups of bottom flexible plugs 7.

[0036] As Figure 7 described, the driving device 9 drives the inner tube body 2 to axially move inside the outer tube body 1, so that the top flexible plug 5 blocks and closes the top sewage discharge port 3, and at the same time the bottom flexible plug 7 opens the bottom sewage discharge port 4, making the bottom inner port 8 communicate with the bottom sewage discharge port 4. The water in the lower layer of the aquaculture pond enters the inner tube body 2, and the lower layer of water is transported through the inner tube body 2 to the sewage discharge port at the bottom of the aquaculture pond for discharge. At the same time, the top flexible plug 5 blocks and closes the top sewage discharge port 3, so that the water in the upper layer of the aquaculture pond cannot be discharged through the inner tube body 2.

[0037] As Figure 8 shown, the driving device 9 drives the inner tube body 2 to axially move inside the outer tube body 1, so that the top flexible plug 5 opens the top sewage discharge port 3. At this time, the top inner port 6 communicates with the top sewage discharge port 3, making the water in the upper layer of the aquaculture pond enter the inner tube body 2, and the upper layer of water is transported through the inner tube body 2 to the sewage discharge port at the bottom of the aquaculture pond for discharge. At the same time, the bottom flexible plug 7 blocks and closes the bottom sewage discharge port 4, so that the water in the lower layer of the aquaculture pond cannot be discharged through the inner tube body 2.

[0038] The inner tube body 2 is driven axially by the driving device 9, so as to open the top sewage outlet 3 while closing the bottom sewage outlet 4, or to open the bottom sewage outlet 4 while closing the top sewage outlet 3, thereby discharging the water in the upper and lower layers of the aquaculture pond and effectively discharging the dirt in the upper and lower layers of the aquaculture pond.

[0039] Furthermore, the top flexible plug 5 and the bottom flexible plug 7 are made of flexible rubber material.

[0040] Embodiment 2:

[0041] A sewage pipe applicable to an industrial aquaculture pond is improved on the basis of Embodiment 1. As Figure 3 and Figure 4 shown, the top sewage outlet 3 is located below the water surface, and a cavity is reserved between the top end and the top sewage outlet 3 inside the outer tube body 1. An air inlet pipe A1 and an exhaust pipe A2 are arranged on the side wall of the cavity.

[0042] Under normal conditions, the air pressure inside the cavity is equal to the air pressure in the external environment. When it is necessary to accelerate the speed of water flowing into the inner tube body 2, air is injected into the cavity through the air inlet pipe A1, so that the air pressure inside the cavity is greater than the air pressure in the external environment. Under the action of the positive pressure inside the cavity, the water can flow into the inner tube body 2 more quickly and be discharged. When it is necessary to slow down the speed of water flowing into the inner tube body 2, the air inside the cavity is discharged through the exhaust pipe A2, so that the air pressure inside the cavity is less than the air pressure in the external environment. Under the action of the negative pressure inside the cavity, the speed of water flowing into the inner tube body 2 is slowed down.

[0043] Furthermore, the air inlet pipe A1 is connected to an air inlet pump A11, and the exhaust pipe A2 is connected to an exhaust pump A21. Air is supplemented into the cavity through the air inlet pump A11, thereby increasing the air pressure inside the cavity. The air inside the cavity is discharged through the exhaust pump A21, thereby reducing the air pressure inside the cavity.

[0044] Furthermore, at least one group of pressure membranes A3 are arranged at the top of the cavity. At least one installation opening is arranged at the top of the cavity, and the pressure membranes A3 are encapsulated in the installation openings to ensure that the cavity is in a relatively sealed state through the pressure membranes A3. When the air pressure inside the cavity increases or decreases to a threshold value, the pressure difference between the air pressure inside the cavity and the air pressure in the external environment will exceed the tolerance pressure of the pressure membranes A3, thereby causing the pressure membranes A3 to break. At this time, the cavity is communicated with the external environment so that the air pressure inside the cavity is the same as that in the external environment. Thus, it is avoided that the positive pressure or negative pressure inside the cavity is too large and causes damage to the pipe body.

[0045] Other parts of this embodiment are the same as those of Embodiment 1, so they will not be described in detail.

[0046] Embodiment 3:

[0047] A sewage discharge pipe applicable to industrial aquaculture ponds, improved on the basis of Embodiment 1 or 2, such as Figure 3 As shown, the driving device 9 includes a connecting chuck 91 and a driving cylinder 92. The connecting chuck 91 is clamped to the top end of the inner pipe body 2. The driving cylinder 92 is arranged at the top end of the outer pipe body 1, and the cylinder rod body of the driving cylinder 92 is connected to the top of the connecting chuck 91.

[0048] A bayonet is provided at the top end of the inner pipe body 2. The bottom edge of the connecting chuck 91 is correspondingly clamped with the bayonet to realize the quick connection between the connecting chuck 91 and the inner pipe body 2. The top of the connecting chuck 91 is connected to the cylinder rod body of the driving cylinder 92. Through the telescopic movement of the cylinder rod body, the inner pipe body 2 is driven to axially slide inside the outer pipe body 1.

[0049] Furthermore, as Figure 9 shown, axial guide strips 21 are provided on the outer wall of the inner pipe body 2, and guide grooves 11 are provided on the inner wall of the outer pipe body 1 between the top sewage discharge port 3 and the bottom sewage discharge port 4. The guide strips 21 are slidably connected with the guide grooves 11. Through the sliding connection between the guide grooves 11 and the guide strips 21, the axial sliding of the inner pipe body 2 inside the outer pipe body 1 is guided to ensure that the inner pipe body 2 can slide strictly along the axis.

[0050] Other parts of this embodiment are the same as those of Embodiment 1 or 2, so they will not be elaborated here.

[0051] Embodiment 4:

[0052] A sewage discharge pipe applicable to industrial aquaculture ponds, improved on the basis of any one of Embodiments 1 - 3, such as Figure 1 shown, a top funnel 100 is provided at the outer side of the top of the outer pipe body 1 corresponding to the position of the top sewage discharge port 3, and a bottom funnel 200 is provided at the outer side of the bottom of the outer pipe body 1 corresponding to the position of the bottom sewage discharge port 4.

[0053] The top end of the top funnel 100 is arranged below the water surface, and the bottom end of the top funnel 100 is arranged below or flush with the bottom end of the top sewage discharge port 3. The bottom end of the bottom funnel 200 is arranged below or flush with the bottom end of the bottom sewage discharge port 4. By providing the top funnel 100 and the bottom funnel 200, the water in the upper or lower layer of the aquaculture pond can be collected to the top sewage discharge port 3 or the bottom sewage discharge port 4, ensuring that the water can enter the inner pipe body 2 more concentratedly.

[0054] Furthermore, spiral grooves are provided on the inner walls of both the top funnel 100 and the bottom funnel 200. By providing the spiral grooves, a certain swirling effect can be generated when the water enters the top funnel 100 or the bottom funnel 200, and the water is collected through the swirling effect.

[0055] Furthermore, asFigure 6 As shown, a filter structure 300 is provided in the top sewage outlet 3 and the bottom sewage outlet 4. The water body is filtered through the filter structure 300 to prevent larvae such as fry and shrimp fry in the aquaculture pond from being discharged from the aquaculture pond.

[0056] Other parts of this embodiment are the same as any one of Embodiments 1-3, so they will not be described in detail.

[0057] The above are only the preferred embodiments of the present invention, and do not impose any formal restrictions on the present invention. Any simple modifications and equivalent changes made to the above embodiments based on the technical essence of the present invention all fall within the protection scope of the present invention.
